           WHEREAS, for its lawful corporate purposes, the Company has duly
authorized the issue of its 5 1/4% Convertible Senior Notes due 2010 (the
"Notes"), in an aggregate principal amount not to exceed $1,000,000,000 (or
$1,200,000,000 if the option set forth in Section 3 of the Purchase Agreement
dated January 21, 2000 between the Company and the Placement Agent is exercised
in full) and, to provide the terms and conditions upon which the Notes are to be
authenticated, issued and delivered, the Company has duly authorized the
execution and delivery of this Indenture; and

           WHEREAS, the Notes, the certificate of authentication to be borne by
the Notes, a form of assignment, a form of option to elect repayment upon a
Fundamental Change, and a form of conversion notice to be borne by the Notes are
to be substantially in the forms hereinafter provided for; and

           WHEREAS, all acts and things necessary to make the Notes, when
executed by the Company and authenticated and delivered by the Trustee or a duly
authorized authenticating agent, as in this Indenture provided, the valid,
binding and legal obligations of the Company, and to constitute these presents a
valid agreement according to its terms, have been done and performed, and the
execution of this Indenture and the issue hereunder of the Notes have in all
respects been duly authorized.

           NOW, THEREFORE, THIS INDENTURE WITNESSETH:

           That in order to declare the terms and conditions upon which the
Notes are, and are to be, authenticated, issued and delivered, and in
consideration of the premises and of the purchase and acceptance of the Notes by
the holders thereof, the Company covenants and agrees with the Trustee for the
equal and proportionate benefit of the respective holders from time to time of
the Notes (except as otherwise provided below), as follows:

           The Person in whose name any Note (or its Predecessor Note) is
registered on the Note register at the close of business on any record date with
respect to any interest payment date shall be entitled to receive the interest
(including Liquidated Damages Amount, if any) payable on such interest payment
date, except (i) that the interest (including Liquidated Damages Amount, if

principal is payable and (ii) as set forth in the next succeeding sentence. In
the case of any Note (or portion thereof) which is converted into Common Stock

Repurchase Date (as defined in Section 3.5) which occurs during such period, the
Company shall not be required to pay interest on such interest payment date in
respect of any such Note (or portion thereof) except to the extent required to
be paid upon redemption of such Note or portion thereof pursuant to Section 3.3
or 3.5 hereof or (ii) if otherwise, any Note (or portion thereof) submitted for
conversion during such period must be accompanied by funds equal to the interest
payable on such succeeding interest payment date on the principal amount so
converted. Interest (including Liquidated Damages Amount, if any) shall be
payable at the office of the Company maintained by the Company for such purposes
in the Borough of Manhattan, The City of New York, which shall initially be an
office or agency of the Trustee and may, as the Company shall specify to the
paying agent in writing by each record date, be paid either (i) by check mailed
to the address of the Person entitled thereto as it appears in the Note register
(provided that any holder of Notes with an aggregate principal amount in excess
of $10,000,000 shall, at the written election of such holder, filed on or before
the relevant record date with the Trustee, be paid by wire transfer in
immediately available funds) or (ii) by transfer to an account maintained by

which is payable, but is not punctually paid or duly provided for, on any
January 15 or July 15 (herein called "Defaulted Interest") shall forthwith cease
to be payable to the Noteholder on the relevant record date by virtue of his
having been such Noteholder; and such Defaulted Interest shall be paid by the
Company, at its election in each case, as provided in clause (1) or (2) below:

               (1) The Company may elect to make payment of any Defaulted
Interest to the Persons in whose names the Notes (or their respective
Predecessor Notes) 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 to be paid on each Note and the date of the payment (which
shall be not less than 25 days after the receipt by the Trustee of such notice,
unless the Trustee shall consent to an earlier date), and at the same time the
Company shall deposit with the Trustee an amount of money equal to the aggregate
amount to be paid in respect of such Defaulted Interest or shall make
arrangements satisfactory to the Trustee for such deposit prior to the date of
the proposed payment, such money when deposited to be held in trust for the
benefit of the Person 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 ten days prior to the date of the proposed payment, and not less than ten
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 Noteholder at his

                                       8
   16

address as it appears in the Note register, not less than ten 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 Notes (or their
respective Predecessor Notes) were registered at the close of business on such
special record date and shall no longer be payable pursuant to the following
clause (2) of this Section 2.3.

               (2) The Company may make payment of any Defaulted Interest in any
other lawful manner not inconsistent with the requirements of any securities
exchange or automated quotation system on which the Notes may be listed or
designated for issuance, and upon such notice as may be required by such
exchange or automated quotation system, 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.

          SECTION 2.4 EXECUTION OF NOTES. The Notes (a) shall be signed in the

Secretary or any of its Assistant Secretaries or its Finance Director,
Treasurer, Controller or any of its Assistant Treasurers or any other officer

certificate of authentication substantially in the form set forth on the form of
Note attached as Exhibit A hereto, manually executed by the Trustee (or an
authenticating agent appointed by the Trustee as provided by Section 15.11),
shall be entitled to the benefits of this Indenture or be valid or obligatory
for any purpose. Such certificate by the Trustee (or such an authenticating
agent) upon any Note executed by the Company shall be conclusive evidence that
the Note so authenticated has been duly authenticated and delivered hereunder
and that the holder is entitled to the benefits of this Indenture.

          In case any officer of the Company who shall have signed any of the
Notes shall cease to be such officer before the Notes so signed shall have been
authenticated and delivered by the Trustee, or disposed of by the Company, such
Notes nevertheless may be authenticated and delivered or disposed of as though
the person who signed such Notes had not ceased to be such officer of the
Company; and any Note may be signed on behalf of the Company by such persons as,
at the actual date of the execution of such Note, shall be the proper officers
of the Company, although at the date of the execution of this Indenture any such
person was not such an officer.

Trustee shall authenticate and deliver, in the name of the designated transferee
or transferees, one or more new Notes of any authorized denominations and of a
like aggregate principal amount and bearing such restrictive legends as may be
required by this Indenture.

denominations and of a like aggregate principal amount, upon surrender of the
Notes to be exchanged at any such office or agency maintained by the Company
pursuant to Section 4.2. Whenever any Notes are so surrendered for exchange, the
Company shall execute, and the Trustee shall authenticate and deliver, the Notes
which the Noteholder making the exchange is entitled to receive bearing
registration numbers not contemporaneously outstanding.

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

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

exchange of Notes, but the Company may require payment of a sum sufficient to
cover any tax, assessment or other governmental charge that may be imposed in
connection with any registration of transfer or exchange of Notes.

          Neither the Company nor the Trustee nor any Note registrar shall be
required to exchange or register a transfer of (a) any Notes for a period of 15
days next preceding any selection of Notes to be redeemed or (b) any Notes or
portions thereof called for redemption pursuant to Section 3.1 or (c) any Notes
or portions thereof surrendered for conversion pursuant to Article XIV or (d)
any Notes or portions thereof tendered for repurchase (and not withdrawn)
pursuant to Section 3.5.

               (b) So long as the Notes are eligible for book-entry settlement
with the Depositary, or unless otherwise required by law, all Notes that, upon
initial issuance are beneficially owned by QIBs or as a result of a sale or
transfer after initial issuance are beneficially owned by QIBs, will be
represented by one or more Notes in global form registered in the name of the
Depositary or the nominee of the Depositary (the "Global Note"), except as
otherwise specified below. The transfer and exchange of beneficial interests in
any such Global Note shall be effected through the Depositary in accordance with
this Indenture and the procedures of the Depositary therefor. The Trustee shall
make appropriate endorsements to reflect increases or decreases in the principal
amounts of any such Global Note as set forth on the


                                       10

   18

face of the Note ("Principal Amount") to reflect any such transfers. Except as
provided below, beneficial owners of a Global Note 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 Notes in global form.

               (c) So long as the Notes are eligible for book-entry settlement,
or unless otherwise required by law, upon any transfer of a definitive Note to a
QIB in accordance with Rule 144A, and upon receipt of the definitive Note or
Notes being so transferred, together with a certification, substantially in the
form on the reverse of the Note, from the transferor that the transfer is being
made in compliance with Rule 144A (or other evidence satisfactory to the
Trustee), the Trustee shall make an endorsement on the Global Note to reflect an
increase in the aggregate Principal Amount of the Notes represented by such Note
in global form, and the Trustee shall cancel such definitive Note or Notes in
accordance with the standing instructions and procedures of the Depositary;
provided that no definitive Note, or portion thereof, in respect of which the
Company or an Affiliate of the Company held any beneficial interest shall be
included in such Note in global form until such definitive Note is freely
tradable in accordance with Rule 144(k); provided further that the Trustee shall
issue Notes in definitive form upon any transfer of a beneficial interest in the
Note in global form to the Company or any Affiliate of the Company.

          Any Note in global form may be endorsed with or have incorporated in
the text thereof such legends or recitals or changes not inconsistent with the
provisions of this Indenture as may be required by the Custodian, the Depositary
or by the National Association of Securities Dealers, Inc. in order for the
Notes to be tradeable on The Portal Market or as may be required for the Notes
to be tradeable on any other market developed for trading of securities pursuant
to Rule 144A or required to comply with any applicable law or any regulation
thereunder or with the rules and regulations of any securities exchange or
automated quotation system upon which the Notes may be listed or traded or to
conform with any usage with respect thereto, or to indicate any special
limitations or restrictions to which any particular Notes are subject.

          Prior to any sale or transfer of a Note to an Institutional
Accredited Investor (other than pursuant to a registration statement that has
been declared effective under the Securities Act), (i) such Institutional
Accredited Investor shall furnish to the Company and/or the Trustee a signed
letter containing representations and agreements relating to restrictions on
transfer substantially in the form set forth in Exhibit B to this Indenture, and
(ii) the seller or transferor must furnish to the Trustee such certifications,
legal opinions or other information as the Trustee reasonably requires to
confirm that such sale or transfer is being made pursuant to an exemption from,
or in a transaction not subject to, the registration requirements of the
Securities Act. Upon any transfer of a beneficial interest in the Global Note to
an Institutional Accredited Investor, the Trustee shall make an endorsement on
the Global Note to reflect a decrease in the aggregate Principal Amount of the
Notes represented by such Note in global form, and the Company shall execute a
definitive Note or Notes in exchange therefor, and the Trustee, upon receipt of
such definitive Note or Notes and the written order of the Company, shall
authenticate and deliver such definitive Note or Notes.

               (d) Every Note that bears or is required under this Section
2.5(d) to bear the legend set forth in this Section 2.5(d) (together with any
Common Stock issued upon conversion of the Notes and required to bear the legend
set forth in Section 2.5(e), collectively, the

                                       11

forth in this Section 2.5(d) (including those set forth in the legend set forth

of the Company, and the holder of each such Restricted Security, by such
holder's acceptance thereof, agrees to be bound by all such restrictions on
transfer. As used in Sections 2.5(d) and 2.5(e), the term "transfer" encompasses
any sale, pledge, transfer or other disposition whatsoever, directly or
indirectly, of any Restricted Security or any interest therein.

          Until the expiration of the holding period applicable to sales
thereof under Rule 144(k) under the Securities Act (or any successor provision),
any certificate evidencing such Note (and all securities issued in exchange
therefor or substitution thereof, other than Common Stock, if any, issued upon
conversion thereof, which shall bear the legend set forth in Section 2.5(e), if
applicable) shall bear a legend in substantially the following form, unless such
Note has been sold pursuant to a registration statement that has been declared
effective under the Securities Act (and which continues to be effective at the
time of such transfer), or unless otherwise agreed by the Company in writing,
with written notice thereof to the Trustee:

          THE NOTE EVIDENCED HEREBY HAS NOT BEEN REGISTERED UNDER THE UNITED
          STATES SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), OR
          ANY STATE SECURITIES LAWS, AND, ACCORDINGLY, MAY NOT BE OFFERED OR
          SOLD WITHIN THE UNITED STATES OR TO, OR FOR THE ACCOUNT OR BENEFIT OF,
          UNITED STATES PERSONS EXCEPT AS SET FORTH IN THE FOLLOWING SENTENCE.
          BY ITS ACQUISITION HEREOF, THE HOLDER (1) REPRESENTS THAT (A) IT IS A
          "QUALIFIED INSTITUTIONAL BUYER" (AS DEFINED IN RULE 144A UNDER THE
          SECURITIES ACT) OR (B) IT IS AN INSTITUTIONAL "ACCREDITED INVESTOR"
          (AS DEFINED IN RULE 501(A)(1), (2), (3) OR (7) UNDER THE SECURITIES
          ACT) ("INSTITUTIONAL ACCREDITED INVESTOR") ACQUIRING THIS NOTE OTHER
          THAN IN THE OFFERING DISTRIBUTION FROM THE INITIAL PURCHASER THEREOF;
          (2) AGREES THAT IT WILL NOT, PRIOR TO EXPIRATION OF THE HOLDING PERIOD
          APPLICABLE TO SALES OF THE NOTE EVIDENCED HEREBY UNDER RULE 144(K)
          UNDER THE SECURITIES ACT (OR ANY SUCCESSOR PROVISION), RESELL OR
          OTHERWISE TRANSFER THE NOTE EVIDENCED HEREBY OR THE COMMON STOCK
          ISSUABLE UPON CONVERSION OF SUCH NOTE EXCEPT (A) TO NEXTEL
          COMMUNICATIONS, INC. OR ANY SUBSIDIARY THEREOF, (B) TO A QUALIFIED
          INSTITUTIONAL BUYER IN COMPLIANCE WITH RULE 144A UNDER THE SECURITIES
          ACT, (C) TO AN INSTITUTIONAL ACCREDITED INVESTOR THAT, PRIOR TO SUCH
          TRANSFER, FURNISHES TO HARRIS TRUST AND SAVINGS BANK, AS TRUSTEE (OR A
          SUCCESSOR TRUSTEE), A SIGNED LETTER CONTAINING CERTAIN REPRESENTATIONS
          AND AGREEMENTS RELATING TO THE RESTRICTIONS ON TRANSFER OF THE NOTE
          EVIDENCED HEREBY (THE FORM OF WHICH LETTER CAN BE OBTAINED FROM THE
          TRUSTEE), (D) PURSUANT TO THE EXEMPTION FROM REGISTRATION PROVIDED BY
          RULE 144 UNDER THE

                                       12
   20

          SECURITIES ACT (IF AVAILABLE) OR (E) PURSUANT TO A REGISTRATION
          STATEMENT WHICH HAS BEEN DECLARED EFFECTIVE UNDER THE SECURITIES ACT
          (AND WHICH CONTINUES TO BE EFFECTIVE AT THE TIME OF SUCH TRANSFER);
          (3) PRIOR TO SUCH TRANSFER (OTHER THAN A TRANSFER PURSUANT TO CLAUSE
          (2)(E) ABOVE), IT WILL FURNISH TO HARRIS TRUST AND SAVINGS BANK, AS
          TRUSTEE (OR A SUCCESSOR TRUSTEE, AS APPLICABLE), SUCH CERTIFICATIONS,
          LEGAL OPINIONS OR OTHER INFORMATION AS IT MAY REASONABLY REQUIRE TO
          CONFIRM THAT SUCH TRANSFER IS BEING MADE PURSUANT TO AN EXEMPTION
          FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION
          REQUIREMENTS OF THE SECURITIES ACT AND (4) AGREES THAT IT WILL DELIVER
          TO EACH PERSON TO WHOM THE NOTE EVIDENCED HEREBY IS TRANSFERRED A
          NOTICE SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND. IN CONNECTION WITH
          ANY TRANSFER OF THE NOTE EVIDENCED HEREBY PRIOR TO THE EXPIRATION OF
          THE HOLDING PERIOD APPLICABLE TO SALES OF THE NOTE EVIDENCED HEREBY
          UNDER RULE 144(K) UNDER THE SECURITIES ACT (OR ANY SUCCESSOR
          PROVISION), THE HOLDER MUST CHECK THE APPROPRIATE BOX SET FORTH ON THE
          REVERSE HEREOF RELATING TO THE MANNER OF SUCH TRANSFER AND SUBMIT THIS
          CERTIFICATE TO HARRIS TRUST AND SAVINGS BANK, AS TRUSTEE (OR A
          SUCCESSOR TRUSTEE, AS APPLICABLE). IF THE PROPOSED TRANSFEREE IS AN
          INSTITUTIONAL ACCREDITED INVESTOR, THE HOLDER MUST, PRIOR TO SUCH
          TRANSFER, FURNISH TO HARRIS TRUST AND SAVINGS BANK, AS TRUSTEE (OR A
          SUCCESSOR TRUSTEE, AS APPLICABLE), SUCH CERTIFICATIONS, LEGAL OPINIONS
          OR OTHER INFORMATION AS SUCH TRUSTEE MAY REASONABLY REQUIRE TO CONFIRM
          THAT SUCH TRANSFER IS BEING MADE PURSUANT TO AN EXEMPTION FROM, OR IN
          A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE
          SECURITIES ACT. THIS LEGEND WILL BE REMOVED UPON THE EARLIER OF THE
          TRANSFER OF THE NOTE EVIDENCED HEREBY PURSUANT TO CLAUSE (2)(E) ABOVE
          OR UPON ANY TRANSFER OF THE NOTES EVIDENCED HEREBY UNDER RULE 144(K)
          UNDER THE SECURITIES ACT (OR ANY SUCCESSOR PROVISION). AS USED HEREIN,
          THE TERMS "UNITED STATES" AND "UNITED STATES PERSONS" HAVE THE
          MEANINGS GIVEN TO THEM BY REGULATION S UNDER THE SECURITIES ACT.

          Any Note (or security issued in exchange or substitution therefor) as
to which such restrictions on transfer shall have expired in accordance with
their terms or as to conditions for removal of the foregoing legend set forth
therein have been satisfied may, upon surrender of such Note for exchange to the
Note registrar in accordance with the provisions of this Section 2.5, be
exchanged for a new Note or Notes, of like tenor and aggregate principal amount,
which shall not bear the restrictive legend required by this Section 2.5(d).

                                       13
   21

           Notwithstanding any other provisions of this Indenture (other than
the provisions set forth in the third paragraph of Section 2.5(c) and in this
Section 2.5(d)), a Note in global form may not be transferred as a whole or in
part except by the Depositary to a nominee of the Depositary or by a nominee of
the Depositary to the Depositary or another nominee of the Depositary or by the
Depositary or any such nominee to a successor Depositary or a nominee of such
successor Depositary.

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

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

          If a Note in certificated form is issued in exchange for any portion
of a Note in global form after the close of business at the office or agency
where such exchange occurs on any record date and before the opening of business
at such office or agency on the next succeeding interest payment date, interest
will not be payable on such interest payment date in respect of such Note, but
will be payable on such interest payment date, subject to the provisions of
Section 2.3, only to the Person to whom interest in respect of such portion of
such Note in global form is payable in accordance with the provisions of this
Indenture.

          Notes in certificated form issued in exchange for all or a part of a
Note in global form pursuant to this Section 2.5 shall be registered in such
names and in such authorized denominations as the Depositary, pursuant to
instructions from its direct or indirect participants or otherwise, shall
instruct the Trustee. Upon execution and authentication, the Trustee shall
deliver such Notes in certificated form to the Persons in whose names such Notes
in certificated form are so registered.

          At such time as all interests in a Note in global form have been
redeemed, converted, canceled, exchanged for Notes in certificated form, or
transferred to a transferee who receives Notes in certificated form thereof,
such Note in global form shall, upon receipt thereof, be canceled by the Trustee
in accordance with standing procedures and instructions existing between the
Depositary and the Custodian. At any time prior to such cancellation, if any
interest in a global Note is exchanged for Notes in certificated form, redeemed,
converted, repurchased or canceled, exchanged for Notes in certificated form or
transferred to a transferee who receives Notes in certificated form therefor or
any Note in certificated form is exchanged or transferred for part of a Note in
global form, the principal amount of such Note in global form shall, in
accordance with the standing procedures and instructions existing between the
Depositary and the Custodian, be appropriately reduced or increased, as the case
may be, and an endorsement

                                       14
   22

shall be made on such Note in global form, by the Trustee or the Custodian, at
the direction of the Trustee, to reflect such reduction or increase.

               (e) Until the expiration of the holding period applicable to
sales thereof under Rule 144(k) under the Securities Act (or any successor
provision), any stock certificate representing Common Stock issued upon
conversion of any Note shall bear a legend in substantially the following form,
unless such Common Stock has been sold pursuant to a registration statement that
has been declared effective under the Securities Act (and which continues to be
effective at the time of such transfer) or such Common Stock has been issued
upon conversion of Notes that have been transferred pursuant to a registration
statement that has been declared effective under the Securities Act, or unless
otherwise agreed by the Company in writing with written notice thereof to the
transfer agent:

               THE COMMON STOCK EVIDENCED HEREBY HAS NOT BEEN REGISTERED UNDER
          THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES
          ACT"), OR ANY STATE SECURITIES LAWS, AND, ACCORDINGLY, MAY NOT BE
          OFFERED OR SOLD WITHIN THE UNITED STATES OR TO, OR FOR THE ACCOUNT OR
          BENEFIT OF, UNITED STATES PERSONS EXCEPT AS SET FORTH IN THE FOLLOWING
          SENTENCE. THE HOLDER HEREOF AGREES THAT UNTIL THE EXPIRATION OF THE
          HOLDING PERIOD APPLICABLE TO SALES OF THE SECURITY EVIDENCED HEREBY
          UNDER RULE 144(K) UNDER THE SECURITIES ACT (OR ANY SUCCESSOR
          PROVISION), (1) IT WILL NOT RESELL OR OTHERWISE TRANSFER THE COMMON
          STOCK EVIDENCED HEREBY EXCEPT (A) TO NEXTEL COMMUNICATIONS, INC. OR
          ANY SUBSIDIARY THEREOF, (B) TO A "QUALIFIED INSTITUTIONAL BUYER" (AS
          DEFINED IN RULE 144A UNDER THE SECURITIES ACT) OR TO AN INSTITUTIONAL
          "ACCREDITED INVESTOR" (AS DEFINED IN RULE 501(A)(1), (2), (3) OR (7)
          UNDER THE SECURITIES ACT) THAT PRIOR TO SUCH TRANSFER, FURNISHES TO
          EQUISERVE LLP, AS TRANSFER AGENT (OR A SUCCESSOR TRANSFER AGENT, AS
          APPLICABLE), A SIGNED LETTER CONTAINING CERTAIN REPRESENTATIONS AND
          AGREEMENTS RELATING TO THE RESTRICTIONS ON TRANSFER OF THE COMMON
          STOCK EVIDENCED HEREBY (THE FORM OF WHICH LETTER CAN BE OBTAINED FROM
          SUCH TRANSFER AGENT OR A SUCCESSOR TRANSFER AGENT, AS APPLICABLE), (C)
          PURSUANT TO THE EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144 UNDER
          THE SECURITIES ACT (IF AVAILABLE), OR (D) PURSUANT TO A REGISTRATION
          STATEMENT WHICH HAS BEEN DECLARED EFFECTIVE UNDER THE SECURITIES ACT
          (AND WHICH CONTINUES TO BE EFFECTIVE AT THE TIME OF SUCH TRANSFER);
          (2) PRIOR TO SUCH TRANSFER (OTHER THAN A TRANSFER PURSUANT TO CLAUSE
          (1)(D) ABOVE), IT WILL FURNISH TO EQUISERVE LLP, AS TRANSFER AGENT (OR
          A SUCCESSOR TRANSFER AGENT, AS APPLICABLE), SUCH CERTIFICATIONS, LEGAL
          OPINIONS OR OTHER INFORMATION AS THE TRANSFER AGENT MAY REASONABLY
          REQUIRE TO CONFIRM THAT SUCH TRANSFER IS BEING MADE PURSUANT TO AN
          EXEMPTION FROM, OR IN A

                                       15
   23

          TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE
          SECURITIES ACT AND (3) IT WILL DELIVER TO EACH PERSON TO WHOM THE
          COMMON STOCK EVIDENCED HEREBY IS TRANSFERRED (OTHER THAN A TRANSFER
          PURSUANT TO CLAUSE 1(D) ABOVE) A NOTICE SUBSTANTIALLY TO THE EFFECT OF
          THIS LEGEND. THIS LEGEND WILL BE REMOVED UPON THE EARLIER OF THE
          TRANSFER OF THE COMMON STOCK EVIDENCED HEREBY PURSUANT TO CLAUSE
          (1)(D) ABOVE OR UPON ANY TRANSFER OF THE COMMON STOCK EVIDENCED HEREBY
          AFTER THE EXPIRATION OF THE HOLDING PERIOD APPLICABLE TO SALES OF THE
          SECURITY EVIDENCED HEREBY UNDER RULE 144(K) UNDER THE SECURITIES ACT
          (OR ANY SUCCESSOR PROVISION). AS USED HEREIN, THE TERMS "UNITED
          STATES" AND "UNITED STATES PERSONS" HAVE THE MEANINGS GIVEN TO THEM BY
          REGULATION S UNDER THE SECURITIES ACT.

          Any such Common Stock as to which such restrictions on transfer shall
have expired in accordance with their terms or as to which the conditions for
removal of the foregoing legend set forth therein have been satisfied may, upon
surrender of the certificates representing such shares of Common Stock for
exchange in accordance with the procedures of the transfer agent for the Common
Stock, be exchanged for a new certificate or certificates for a like number of
shares of Common Stock, which shall bear the restrictive legend required by this
Section 2.5(e).

               (f) Any Note or Common Stock issued upon the conversion or
exchange of a Note that, prior to the expiration of the holding period
applicable to sales thereof under Rule 144(k) under the Securities Act (or any
successor provision), is purchased or owned by the Company or any Affiliate
thereof may not be resold by the Company or such Affiliate unless registered
under the Securities Act or resold pursuant to an exemption from the
registration requirements of the Securities Act in a transaction which results
in such Notes or Common Stock, as the case may be, no longer being "restricted
securities" (as defined under Rule 144).

          SECTION 2.6 MUTILATED, DESTROYED, LOST OR STOLEN NOTES. In case any
Note shall become mutilated or be destroyed, lost or stolen, the Company in its
discretion may execute, and upon its written request the Trustee or an
authenticating agent appointed by the Trustee shall authenticate and make
available for delivery, a new Note, bearing a number not contemporaneously
outstanding, in exchange and substitution for the mutilated Note, or in lieu of
and in substitution for the Note so destroyed, lost or stolen. In every case the
applicant for a substituted Note shall furnish to the Company, to the Trustee
and, if applicable, to such authenticating agent such security or indemnity as
may be required by them to save each of them harmless for any loss, liability,
cost or expense caused by or connected with such substitution, and, in every
case of destruction, loss or theft, the applicant shall also furnish to the
Company, to the Trustee and, if applicable, to such authenticating agent
evidence to their satisfaction of the destruction, loss or theft of such Note
and of the ownership thereof.

          Following receipt by the Trustee or such authenticating agent, as the
case may be, of satisfactory security or indemnity and evidence, as described in
the preceding paragraph, the Trustee or such authenticating agent may
authenticate any such substituted Note and make available for delivery such
Note. Upon the issuance of any substituted Note, the Company may

                                       16
   24

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 connected
therewith. In case any Note which has matured or is about to mature or has been
called for redemption or has been tendered for repurchase (and not withdrawn) or
is about to be converted into Common Stock shall become mutilated or be
destroyed, lost or stolen, the Company may, instead of issuing a substitute
Note, pay or authorize the payment of or convert or authorize the conversion of
the same (without surrender thereof except in the case of a mutilated Note), as
the case may be, if the applicant for such payment or conversion shall furnish
to the Company, to the Trustee and, if applicable, to such authenticating agent
such security or indemnity as may be required by them to save each of them
harmless for any loss, liability, cost or expense caused by or connected with
such substitution, and, in case of destruction, loss or theft, evidence
satisfactory to the Company, the Trustee and, if applicable, any paying agent or
conversion agent of the destruction, loss or theft of such Note and of the
ownership thereof.

          Every substitute Note issued pursuant to the provisions of this
Section 2.6 by virtue of the fact that any Note is destroyed, lost or stolen
shall constitute an additional contractual obligation of the Company, whether or
not the destroyed, lost or stolen Note shall be found at any time, and shall be
entitled to all the benefits of (but shall be subject to all the limitations set
forth in) this Indenture equally and proportionately with any and all other
Notes duly issued hereunder. To the extent permitted by law, all Notes shall be
held and owned upon the express condition that the foregoing provisions are
exclusive with respect to the replacement or payment or conversion of mutilated,
destroyed, lost or stolen Notes and shall preclude any and all other rights or
remedies notwithstanding any law or statute existing or hereafter enacted to the
contrary with respect to the replacement or payment or conversion of negotiable
instruments or other securities without their surrender.

          SECTION 2.7 TEMPORARY NOTES. Pending the preparation of Notes in
certificated form, the Company may execute and the Trustee or an authenticating
agent appointed by the Trustee shall, upon the written request of the Company,
authenticate and deliver temporary Notes (printed or lithographed). Temporary
Notes shall be issuable in any authorized denomination, and substantially in the
form of the Notes in certificated form, but with such omissions, insertions and
variations as may be appropriate for temporary Notes, all as may be determined
by the Company. Every such temporary Note shall be executed by the Company and
authenticated by the Trustee or such authenticating agent upon the same
conditions and in substantially the same manner, and with the same effect, as
the Notes in certificated form. Without unreasonable delay the Company will
execute and deliver to the Trustee or such authenticating agent Notes in
certificated form (other than in the case of Notes in global form) and thereupon
any or all temporary Notes (other than any such Note in global form) may be
surrendered in exchange therefor, at each office or agency maintained by the
Company pursuant to Section 4.2 and the Trustee or such authenticating agent
shall authenticate and make available for delivery in exchange for such
temporary Notes an equal aggregate principal amount of Notes in certificated
form. Such exchange shall be made by the Company at its own expense and without
any charge therefor. Until so exchanged, the temporary Notes shall in all
respects be entitled to the same benefits and subject to the same limitations
under this Indenture as Notes in certificated form authenticated and delivered
hereunder.

          SECTION 2.8 CANCELLATION OF NOTES PAID, ETC. All Notes surrendered
for the purpose of payment, redemption, repurchase, conversion, exchange or
registration of transfer shall, if

                                       17
   25

surrendered to the Company or any paying agent or any Note registrar or any
conversion agent, be surrendered to the Trustee and promptly canceled by it, or,
if surrendered to the Trustee, shall be promptly canceled by it, and no Notes
shall be issued in lieu thereof except as expressly permitted by any of the
provisions of this Indenture. The Trustee shall dispose of such canceled Notes
in accordance with its customary procedures. If the Company shall acquire any of
the Notes, such acquisition shall not operate as a redemption or satisfaction of
the indebtedness represented by such Notes unless and until the same are
delivered to the Trustee for cancellation.

          SECTION 2.9 CUSIP NUMBERS. The Company in issuing the Notes 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 Noteholders;
provided that any such notice may state that no representation is made as to the
correctness of such numbers either as printed on the Notes or as contained in
any notice of a redemption and that reliance may be placed only on the other
identification numbers printed on the Notes, 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.

                                   ARTICLE III

                        REDEMPTION OR REPURCHASE OF NOTES

          SECTION 3.1 REDEMPTION BY THE COMPANY. At any time on or after
January 18, 2003 and prior to maturity, the Notes may be redeemed at the option
of the Company (an "Optional Redemption"), in whole or in part, upon notice as
set forth in Section 3.2, at the following optional redemption prices (expressed
as percentages of the principal amount), together in each case with accrued and
unpaid interest, if any (including Liquidated Damages Amount, if any), to, but
excluding, the date fixed for redemption.

          If redeemed during the period beginning January 18, 2003 and ending
on January 14, 2004, at a redemption price of 103.500% and if redeemed during
the 12-month period beginning January 15:



                        Year                               Redemption Price
                                                       
                        2004...................................102.917%
                        2005...................................102.333%
                        2006...................................101.750%
                        2007...................................101.167%
                        2008...................................100.583%


and 100% if on or after January 15, 2009; provided that if the date fixed for
redemption is after an interest payment record date and on or before January 15
or July 15, then the interest payable on the redemption date will be paid to the
Person who, on the preceding January 1 or July 1, respectively, is the holder of
record.

          SECTION 3.2 NOTICE OF REDEMPTION; SELECTION OF NOTES FOR REDEMPTION.
In case the Company shall desire to exercise the right to redeem all or, as the
case may be, any part of the Notes pursuant to Section 3.1, it shall fix a date
for redemption and it or, at its written request

                                       18
   26

received by the Trustee not fewer than 45 days prior (or such shorter period of
time as may be acceptable to the Trustee) to the date fixed for redemption, the
Trustee in the name of and at the expense of the Company, shall publish in
certain newspapers a notice pursuant to Section 15.3 and mail or cause to be
mailed a notice of such redemption not fewer than 30 days prior to the date
fixed for redemption to the holders of Notes so to be redeemed as a whole or in
part, at their last addresses as the same appear on the Note register and shall
also give notice of any such redemption by a release made to Reuters Economic
Services and Bloomberg Business News within the same time period; provided that
if the Company shall give such notice, it shall also give written notice, and
written notice of the Notes to be redeemed to the Trustee. The Company may not
give notice of any redemption of any of the Notes if a default in payment of
interest or premium on the Notes or any other Event of Default has occurred and
is continuing. Such mailing shall be by first class mail and by publication in
certain newspapers pursuant to Section 15.3. The notice if mailed in the manner
herein provided shall be conclusively presumed to have been duly given, whether
or not the holder receives such notice. In any case, failure to give such notice
by mail or any defect in the notice to the holder of any Note designated for
redemption as a whole or in part shall not affect the validity of the
proceedings for the redemption of any other Note.

          Each notice of redemption shall specify the aggregate principal
amount of Notes to be redeemed, the CUSIP number or numbers of the Notes being
redeemed, the date fixed for redemption (which shall be a Business Day), the
redemption price at which Notes are to be redeemed, the place or places of
payment, that payment will be made upon presentation and surrender of such
Notes, that interest accrued to the date fixed for redemption will be paid as
specified in said notice, and that on and after said date interest thereon or on
the portion thereof to be redeemed will cease to accrue. Such notice shall also
state the current Conversion Price and the date on which the right to convert
such Notes or portions thereof into Common Stock will expire. If fewer than all
the Notes are to be redeemed, the notice of redemption shall identify the Notes
to be redeemed (including CUSIP numbers, if any). In case any Note is to be
redeemed in part only, the notice of redemption shall state the portion of the
principal amount thereof to be redeemed and shall state that, on and after the
date fixed for redemption, upon surrender of such Note, a new Note or Notes in
principal amount equal to the unredeemed portion thereof will be issued.

          On or prior to the redemption date specified in the notice of
redemption given as provided in this Section 3.2, the Company will deposit with
the Trustee or with one or more paying agents (or, if the Company is acting as
its own paying agent, set aside, segregate and hold in trust as provided in
Section 4.4) an amount of money in immediately available funds sufficient to
redeem on the redemption date all the Notes (or portions thereof) so called for
redemption (other than those theretofore surrendered for conversion into Common
Stock) at the appropriate redemption price, together with accrued interest to,
but excluding, the date fixed for redemption; provided that if such payment is
made on the redemption date it must be received by the Trustee or paying agent,
as the case may be, by 10:00 a.m. New York City time on such date. If any Note
called for redemption is converted pursuant hereto prior to such redemption, any
money deposited with the Trustee or any paying agent or so segregated and held
in trust for the redemption of such Note shall be paid to the Company upon its
written request, or, if then held by the Company, shall be discharged from such
trust.

                                       19
   27

          Whenever any Notes are to be redeemed, the Company will give the
Trustee written notice in the form of an Officers' Certificate not fewer than 45
days (or such shorter period of time as may be acceptable to the Trustee) prior
to the redemption date as to the aggregate principal amount of Notes to be
redeemed.

          If fewer than all the Notes are to be redeemed, the Trustee shall
select the Notes or portions thereof of the Global Note or the Notes in
certificated form to be redeemed (in principal amounts of $1,000 or integral
multiples thereof), by lot or by another method the Trustee deems fair and
appropriate.

          Upon any redemption of fewer than all Notes, the Company and the
Trustee may (but need not), solely for purposes of determining the pro rata
allocation among such Notes as are unconverted and outstanding at the time of
redemption, treat as outstanding any Notes surrendered for conversion during the
period of 15 days next preceding the mailing of a notice of redemption and may
(but need not) treat as outstanding any Note authenticated and delivered during
such period in exchange for the unconverted portion of any Note converted in
part during such period.

          SECTION 3.3 PAYMENT OF NOTES CALLED FOR REDEMPTION. If notice of
redemption has been given as above provided, the Notes or portion of Notes with
respect to which such notice has been given shall, unless converted into Common
Stock pursuant to the terms hereof, become due and payable on the date fixed for
redemption and at the place or places stated in such notice at the applicable
redemption price, together with interest accrued to (but excluding) the date
fixed for redemption, and on and after said date (unless the Company shall
default in the payment of such Notes at the redemption price, together with
interest accrued to said date) interest on the Notes or portion of Notes so
called for redemption shall cease to accrue and such Notes shall cease after the
close of business on the Business Day next preceding the date fixed for
redemption to be convertible into Common Stock and, except as provided in
Sections 7.11 and 12.4, to be entitled to any benefit or security under this
Indenture, and the holders thereof shall have no right in respect of such Notes
except the right to receive the redemption price thereof and unpaid interest to
(but excluding) the date fixed for redemption. On presentation and surrender of
such Notes at a place of payment in said notice specified, the said Notes or the
specified portions thereof shall be paid and redeemed by the Company at the
applicable redemption price, together with interest accrued thereon to (but
excluding) the date fixed for redemption; provided that, if the applicable
redemption date is an interest payment date, the semi-annual payment of interest
becoming due on such date shall be payable to the holders of such Notes
registered as such on the relevant record date instead of the holders
surrendering such Notes for redemption on such date.

          Upon presentation of any Note redeemed in part only, the Company
shall execute and the Trustee shall authenticate and make available for delivery
to the holder thereof, at the expense of the Company, a new Note or Notes, of
authorized denominations, in principal amount equal to the unredeemed portion of
the Notes so presented.

          Notwithstanding the foregoing, the Trustee shall not redeem any Notes
or mail any notice of redemption during the continuance of a default in payment
of interest or premium on the Notes or if any other Event of Default has
occurred and is continuing. If any Note called for redemption shall not be so
paid upon surrender thereof for redemption, the principal and

                                       20
   28

premium, if any, shall, until paid or duly provided for, bear interest from the
date fixed for redemption at the rate borne by the Note and such Note shall
remain convertible into Common Stock until the principal and premium, if any,
shall have been paid or duly provided for.

          SECTION 3.4 CONVERSION ARRANGEMENT ON CALL FOR REDEMPTION. In
connection with any redemption of Notes, the Company may arrange for the
purchase and conversion of any Notes by an agreement with one or more investment
bankers or other purchasers to purchase such Notes by paying to the Trustee in
trust for the Noteholders, on or before the date fixed for redemption, an amount
not less than the applicable redemption price, together with interest accrued to
(but excluding) the date fixed for redemption, of such Notes. Notwithstanding
anything to the contrary contained in this Article III, the obligation of the
Company to pay the redemption price of such Notes, together with interest
accrued to (but excluding) the date fixed for redemption shall be deemed to be
satisfied and discharged to the extent such amount is so paid by such
purchasers. If such an agreement is entered into, a copy of which will be filed
with the Trustee prior to the date fixed for redemption, any Notes not duly
surrendered for conversion by the holders thereof may, at the option of the
Company, be deemed, to the fullest extent permitted by law, acquired by such
purchasers from such holders and (notwithstanding anything to the contrary
contained in Article XIV) surrendered by such purchasers for conversion, all as
of immediately prior to the close of business on the date fixed for redemption
(and the right to convert any such Notes shall be extended through such time),
subject to payment of the above amount as aforesaid. At the direction of the
Company, the Trustee shall hold and dispose of any such amount paid to it in the
same manner as it would monies deposited with it by the Company for the
redemption of Notes. Without the Trustee's prior written consent, no arrangement
between the Company and such purchasers for the purchase and conversion of any
Notes shall increase or otherwise affect any of the powers, duties,
responsibilities or obligations of the Trustee as set forth in this Indenture.

          SECTION 3.5 REPURCHASE AT OPTION OF HOLDERS.

               (a) If there shall occur a Fundamental Change at any time prior
to maturity, conversion or redemption of the Notes, then each Noteholder shall
have the right, at such holder's option, to require the Company to repurchase
all of such holder's Notes, or any portion thereof that is an integral multiple
of $1,000 principal amount, on the date (the "Repurchase Date") that is 30 days
after the date of the Company Notice (as defined in Section 3.5(b) below) of
such Fundamental Change (or, if such 30th day is not a Business Day, the
immediately preceding Business Day) at a repurchase price equal to 100% of the
principal amount thereof, together with accrued interest to (but excluding) the
Repurchase Date; provided that, if such Repurchase Date is after January 1 or
July 1 and on or before January 15 or July 15, then the interest payable on the
Repurchase Date will be paid to the Person who, on the preceding January 1 or
July 1, respectively, is the holder of record.

          Upon presentation of any Note redeemed in part only, the Company
shall execute and, upon the Company's written direction to the Trustee, the
Trustee shall authenticate and deliver to the holder thereof, at the expense of
the Company, a new Note or Notes, of authorized denominations, in principal
amount equal to the unredeemed portion of the Notes so presented.

               (b) On or before the tenth day after the occurrence of a
Fundamental Change, the Company or, at its written request (which must be
received by the Trustee at least five

                                       21
   29

Business Days prior to the date the Trustee is requested to give notice as
described below, unless the Trustee shall agree in writing to a shorter period),
the Trustee in the name of and at the expense of the Company, shall mail or
cause to be mailed to all holders of record on the date of the Fundamental
Change a notice (the "Company Notice") of the occurrence of such Fundamental
Change and of the repurchase right at the option of the holders arising as a
result thereof. Such notice shall be mailed in the manner and with the effect
set forth in the first paragraph of Section 3.2 (without regard for the time
limits set forth therein), shall be published pursuant to Section 15.3 and shall
be given by a release made to Reuters Economic Services and Bloomberg Business
News within the same time period. If the Company shall give such notice, the
Company shall also deliver a copy of the Company Notice to the Trustee at such
time as it is mailed to Noteholders.

          Each Company Notice shall specify the circumstances constituting the
Fundamental Change, the Repurchase Date, the price at which the Company shall be
obligated to repurchase Notes, the latest time (not less than 30 days after the
date of the Company's notice of a Fundamental Change) on the Repurchase Date by
which the holder must exercise the repurchase right (the "Fundamental Change
Expiration Time"), that the holder shall have the right to withdraw any Notes
surrendered prior to the Fundamental Change Expiration Time, a description of
the procedure which a Noteholder must follow to exercise such repurchase right
and to withdraw any surrendered Notes, the place or places where the holder is
to surrender such holder's Notes, and the amount of interest accrued on each
Note to the Repurchase Date.

          No failure of the Company to give the foregoing notices and no defect
therein shall limit the Noteholders' repurchase rights or affect the validity of
the proceedings for the repurchase of the Notes pursuant to this Section 3.5.

               (c) For a Note to be so repaid at the option of the holder, the
Company must receive at the office or agency of the Company maintained for that
purpose or, at the option of such holder, the Corporate Trust Office, such Note
with the form entitled "Option to Elect Repayment Upon A Fundamental Change" on
the reverse thereof duly completed, together with such Notes duly endorsed for
transfer, on or before the Fundamental Change Expiration Time. All questions as
to the validity, eligibility (including time of receipt) and acceptance of any
Note for repayment shall be determined by the Company, whose determination shall
be final and binding absent manifest error.

               (d) Not later than the Business Day following the Repurchase
Date, the Company will deposit with the Trustee or with one or more paying
agents (or, if the Company is acting as its own paying agent, set aside,
segregate and hold in trust as provided in Section 4.4) an amount of money
sufficient to repay on the Repurchase Date all the Notes to be repaid on such
date at the appropriate repurchase price, together with accrued interest to (but
excluding) the Repurchase Date; provided that if such payment is made on the
Repurchase Date it must be received by the Trustee or paying agent, as the case
may be, by 10:00 a.m. New York City time, on such date. Payment for Notes
surrendered for repurchase (and not withdrawn) prior to the Fundamental Change
Expiration Time will be made promptly (but in no event more than five Business
Days) following the Repurchase Date by mailing checks for the amount payable to
the holders of such Notes entitled thereto as they shall appear on the Note
register.

                                       22
   30

               (e) In the case of a reclassification, change, consolidation,
merger, combination, sale or conveyance to which Section 14.6 applies, but which
does not constitute a Fundamental Change, then the Person formed by such
consolidation or resulting from such merger or which acquires such assets, as
the case may be, shall execute and deliver to the Trustee a supplemental
indenture (accompanied by an Opinion of Counsel stating that, in addition to the
requirements of Section 15.5, such supplemental indenture complies with the
Trust Indenture Act as in force at the date of execution of such supplemental
indenture) modifying the provisions of this Indenture relating to the right of
holders of the Notes to cause the Company to repurchase the Notes following a
Fundamental Change, including without limitation the applicable provisions of
this Section 3.5 and the definitions of Common Stock and Fundamental Change, as
appropriate, as determined in good faith by the Company (which determination
shall be conclusive and binding), to make such provisions apply to the common
stock and the issuer thereof if different from the Company and Common Stock of
the Company (in lieu of the Company and the Common Stock of the Company).

               (f) The Company will comply with the provisions of Rule 13e-4 and
any other tender offer rules under the Exchange Act to the extent then
applicable in connection with the repurchase rights of the holders of Notes in
the event of a Fundamental Change.

               (g) Notwithstanding any provision of this Section 3.5 to the
contrary, the Company may omit to comply with its obligation to repurchase any
Notes upon the occurrence of a Fundamental Change if, prior to the occurrence of
such Fundamental Change, the holders of at least a majority in aggregate
principal amount of the Notes at the time outstanding shall have waived such
compliance, but no such waiver shall extend to or affect the Company's
obligations as set forth in Section 3.5 of this Indenture except to the extent
so expressly waived, and, until such waiver shall become effective, the
obligations of the Company and the duties of the Trustee in respect of Section
3.5 of this Indenture shall remain in full force and effect with respect to any
subsequent or different Fundamental Change.

                                   ARTICLE IV

                       PARTICULAR COVENANTS OF THE COMPANY

          SECTION 4.1 PAYMENT OF PRINCIPAL, PREMIUM AND INTEREST. The Company
covenants and agrees that it will duly and punctually pay or cause to be paid
the principal of and premium, if any, and interest (including Liquidated Damages
Amount, if any), on each of the Notes at the places, at the respective times and
in the manner provided herein and in the Notes.

          SECTION 4.2 MAINTENANCE OF OFFICE OR AGENCY. The Company will
maintain an office or agency in the Borough of Manhattan, The City of New York,
where the Notes may be surrendered for registration of transfer or exchange or
for presentation for payment or for conversion, redemption or repurchase and
where notices and demands to or upon the Company in respect of the Notes 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 not designated or appointed by the Trustee. 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

                                       23
   31

presentations, surrenders, notices and demands may be made or served at the
Corporate Trust Office of the Trustee or an affiliate thereof in the Borough of
Manhattan, The City of New York.

          The Company may also from time to time designate co-registrars and
one or more offices or agencies where the Notes may be presented or surrendered
for any or all such purposes and may from time to time rescind such
designations. The Company will give prompt written notice of any such
designation or rescission and of any change in the location of any such other
office or agency.

          The Company hereby initially designates the Trustee as paying agent,
Note registrar, Custodian and conversion agent and the Corporate Trust Office of
the Trustee or an affiliate thereof in the Borough of Manhattan, The City of New
York as the office or agency of the Company for each of the aforesaid purposes.

          So long as the Trustee is the Note registrar, the Trustee agrees to
mail, or cause to be mailed, the notices set forth in Section 7.8. If
co-registrars have been appointed in accordance with this Section, the Trustee
shall mail such notices only to the Company and the holders of Notes it can
identify from its records.

          SECTION 4.3 APPOINTMENTS TO FILL VACANCIES IN TRUSTEE'S OFFICE. The
Company, whenever necessary to avoid or fill a vacancy in the office of Trustee,
will appoint, in the manner provided in Section 7.8, a Trustee, so that there
shall at all times be a Trustee hereunder.

          SECTION 4.4 PROVISIONS AS TO PAYING AGENT.

               (a) If the Company shall appoint a paying agent other than the
Trustee, or if the Trustee shall appoint such a paying agent, the Company will
cause such paying agent to execute and deliver to the Trustee an instrument in
which such agent shall agree with the Trustee, subject to the provisions of this
Section 4.4:

                    (1) that it will hold all sums held by it as such agent for
the payment of the principal of and premium, if any, or interest on the Notes
(whether such sums have been paid to it by the Company or by any other obligor
on the Notes) in trust for the benefit of the holders of the Notes;

                    (2) that it will give the Trustee notice of any failure by
the Company (or by any other obligor on the Notes) to make any payment of the
principal of and premium, if any, or interest on the Notes when the same shall
be due and payable; and

                    (3) that at any time during the continuance of an Event of
Default, upon request of the Trustee, it will forthwith pay to the Trustee all
sums so held in trust.

          The Company shall, on or before each due date of the principal of,
premium, if any, or interest on the Notes, deposit with the paying agent a sum
sufficient to pay such principal, premium, if any, or interest, and (unless such
paying agent is the Trustee) the Company will promptly notify the Trustee of any
failure to take such action; provided that if such deposit is made on the due
date, such deposit shall be received by the paying agent by 10:00 a.m. New York
City time, on such date.

                                       24
   32



               (b) If the Company shall act as its own paying agent, it will, on
or before each due date of the principal of, premium, if any, or interest
(including Liquidated Damages Amount, if any) on the Notes, set aside, segregate
and hold in trust for the benefit of the holders of the Notes a sum sufficient
to pay such principal, premium, if any, or interest (including Liquidated
Damages Amount, if any) so becoming due and will promptly notify the Trustee of
any failure to take such action and of any failure by the Company (or any other
obligor under the Notes) to make any payment of the principal of, premium, if
any, or interest (including Liquidated Damages Amount, if any) on the Notes when
the same shall become due and payable.

               (c) Anything in this Section 4.4 to the contrary notwithstanding,
the Company may, at any time, for the purpose of obtaining a satisfaction and
discharge of this Indenture, or for any other reason, pay or cause to be paid to
the Trustee all sums held in trust by the Company or any paying agent hereunder
as required by this Section 4.4, such sums to be held by the Trustee upon the
trusts herein contained and upon such payment by the Company or any paying agent
to the Trustee, the Company or such paying agent shall be released from all
further liability with respect to such sums.

               (d) Anything is this Section 4.4 to the contrary notwithstanding,
the agreement to hold sums in trust as provided in this Section 4.4 is subject
to Sections 12.3 and 12.4.

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

          SECTION 4.5 EXISTENCE. Subject to Article XI, the Company will do or
cause to be done all things necessary to preserve and keep in full force and
effect its existence and rights (charter and statutory); provided, however, that
the Company shall not be required to preserve any such right if the Company
shall determine that the preservation thereof is no longer desirable in the
conduct of the business of the Company and that the loss thereof is not
disadvantageous in any material respect to the holders.

          SECTION 4.6 MAINTENANCE OF PROPERTIES. The Company will cause all
properties used or useful in the conduct of its business or the business of any
Significant Subsidiary to be maintained and kept in good condition, repair and
working order and supplied with all necessary equipment and will cause to be
made all necessary repairs, renewals, replacements, betterments and improvements
thereof, all as in the judgment of the Company may be necessary so that the
business carried on in connection therewith may be properly and advantageously
conducted at all times; provided, however, that nothing in this Section shall
prevent the Company from discontinuing the operation or maintenance of any of
such properties if such discontinuance is, in the judgment of the Company,
desirable in the conduct of its business or the business of any Significant
Subsidiary and not disadvantageous in any material respect to the holders.

          SECTION 4.7 PAYMENT OF TAXES AND OTHER CLAIMS. The Company will pay
or discharge, or cause to be paid or discharged, before the same may become
delinquent, (i) all taxes, assessments and governmental charges levied or
imposed upon the Company or any Significant Subsidiary or upon the income,
profits or property of the Company or any Significant

                                       25
   33
Subsidiary, (ii) all claims for labor, materials and supplies which, if unpaid,
might by law become a lien or charge upon the property of the Company or any
Significant Subsidiary and (iii) all stamps and other duties, if any, which may
be imposed by the United States or any political subdivision thereof or therein
in connection with the issuance, transfer, exchange or conversion of any Notes
or with respect to this Indenture; provided, however, that, in the case of
clauses (i) and (ii), the Company shall not be required to pay or discharge or
cause to be paid or discharged any such tax, assessment, charge or claim (A) if
the failure to do so will not, in the aggregate, have a material adverse impact
on the Company, or (B) if the amount, applicability or validity is being
contested in good faith by appropriate proceedings.

          SECTION 4.8 RULE 144A INFORMATION REQUIREMENT. Within the period
prior to the expiration of the holding period applicable to sales thereof under
Rule 144(k) under the Securities Act (or any successor provision), the Company
covenants and agrees that it shall, during any period in which it is not subject
to Section 13 or 15(d) under the Exchange Act, make available to any holder or
beneficial holder of Notes or any Common Stock issued upon conversion thereof
which continue to be Restricted Securities in connection with any sale thereof
and any prospective purchaser of Notes or such Common Stock from such holder or
beneficial holder, the information required pursuant to Rule 144A(d)(4) under
the Securities Act upon the request of any holder or beneficial holder of the
Notes or such Common Stock and it will take such further action as any holder or
beneficial holder of such Notes or such Common Stock may reasonably request, all
to the extent required from time to time to enable such holder or beneficial
holder to sell its Notes or Common Stock without registration under the
Securities Act within the limitation of the exemption provided by Rule 144A, as
such Rule may be amended from time to time. Upon the request of any holder or
any beneficial holder of the Notes or such Common Stock, the Company will
deliver to such holder a written statement as to whether it has complied with
such requirements.

          SECTION 4.9 STAY, EXTENSION AND USURY LAWS. The Company covenants (to
the extent that it may lawfully do so) that it shall not at any time insist
upon, plead, or in any manner whatsoever claim or take the benefit or advantage
of, any stay, extension or usury law or other law which would prohibit or
forgive the Company from paying all or any portion of the principal of, premium,
if any, or interest (including Liquidated Damages Amount, if any) on the Notes
as contemplated herein, wherever enacted, now or at any time hereafter in force,
or which may affect the covenants or the performance of this Indenture and the
Company (to the extent it may lawfully do so) hereby expressly waives all
benefit or advantage of any such law, and covenants that it will not, by resort
to any such law, hinder, delay or impede the execution of any power herein
granted to the Trustee, but will suffer and permit the execution of every such
power as though no such law had been enacted.

          SECTION 4.10 COMPLIANCE CERTIFICATE. The Company shall deliver to the
Trustee, within 120 days after the end of each fiscal year of the Company, a
certificate signed by either the principal executive officer, principal
financial officer or principal accounting officer of the Company, stating
whether or not to the best knowledge of the signer thereof the Company is in
default in the performance and observance of any of the terms, provisions and
conditions of this Indenture (without regard to any period of grace or
requirement of notice provided hereunder) and, if the Company shall be in
default, specifying all such defaults and the nature and the status thereof of
which the signer may have knowledge.

                                       26
   34

          The Company will deliver to the Trustee, forthwith (and in any event
within five Business Days) upon becoming aware of any default in the performance
or observance of any covenant, agreement or condition contained in this
Indenture, any event which, with notice or the lapse of time or both, would
constitute an Event of Default or any Event of Default, an Officers' Certificate
specifying with particularity such default or Event of Default and further
stating what action the Company has taken, is taking or proposes to take with
respect thereto.

          Any notice required to be given under this Section 4.10 shall be
delivered to a Responsible Officer of the Trustee at its Corporate Trust Office.

                                    ARTICLE V

          NOTEHOLDERS' LISTS AND REPORTS BY THE COMPANY AND THE TRUSTEE

          SECTION 5.1 NOTEHOLDERS' LISTS. The Company covenants and agrees that
it will furnish or cause to be furnished to the Trustee, semiannually, not more
than 15 days after each January 1 and July 1 in each year beginning with July 1,
2000, and at such other times as the Trustee may request in writing, within 30
days after receipt by the Company of any such request (or such lesser time as
the Trustee may reasonably request in order to enable it to timely provide any
notice to be provided by it hereunder), a list in such form as the Trustee may
reasonably require of the names and addresses of the holders of Notes as of a
date not more than 15 days (or such other date as the Trustee may reasonably
request in order to so provide any such notices) prior to the time such
information is furnished, except that no such list need be furnished by the
Company to the Trustee so long as the Trustee is acting as the sole Note
registrar.

          SECTION 5.2 PRESERVATION AND DISCLOSURE OF LISTS.

               (a) The Trustee shall preserve, in as current a form as is
reasonably practicable, all information as to the names and addresses of the
holders of Notes contained in the most recent list furnished to it as provided
in Section 5.1 or maintained by the Trustee in its capacity as Note registrar or
co-registrar in respect of the Notes, if so acting. The Trustee may destroy any
list furnished to it as provided in Section 5.1 upon receipt of a new list so
furnished.

               (b) The rights of Noteholders to communicate with other holders
of Notes with respect to their rights under this Indenture or under the Notes,
and the corresponding rights and duties of the Trustee, shall be as provided by
the Trust Indenture Act.

               (c) Every Noteholder, by receiving and holding the same, agrees
with the Company and the Trustee that neither the Company nor the Trustee nor
any agent of either of them shall be held accountable by reason of any
disclosure of information as to names and addresses of holders of Notes made
pursuant to the Trust Indenture Act.

          SECTION 5.3 REPORTS BY TRUSTEE.

               (a) Within 60 days after July 1 of each year commencing with the
year 2000, the Trustee shall transmit to holders of Notes such reports dated as
of July 1 of the year in which such reports are made concerning the Trustee and
its actions under this Indenture as may be

                                       27
   35

required pursuant to the Trust Indenture Act at the times and in the manner
provided pursuant thereto.

               (b) A copy of such report shall, at the time of such transmission
to holders of Notes, be filed by the Trustee with each stock exchange and
automated quotation system upon which the Notes are listed and with the Company.
The Company will promptly notify the Trustee in writing when the Notes are
listed on any stock exchange or automated quotation system or delisted
therefrom.

          SECTION 5.4 REPORTS BY COMPANY. The Company shall file with the
Trustee (and the Commission if at any time after the Indenture becomes qualified
under the Trust Indenture Act), and transmit to holders of Notes, such
information, documents and other reports and such summaries thereof, as may be
required pursuant to the Trust Indenture Act at the times and in the manner
provided pursuant to such Act, whether or not the Notes are governed by such
Act; provided that any such information, documents or reports required to be
filed with the Commission pursuant to Section 13 or 15(d) of the Exchange Act
shall be filed with the Trustee within 15 days after the same is so required to
be filed with the Commission. 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 its covenants hereunder (as to which the
Trustee is entitled to rely exclusively on Officers' Certificates).

                                   ARTICLE VI

                     REMEDIES OF THE TRUSTEE AND NOTEHOLDERS
                             ON AN EVENT OF DEFAULT

          SECTION 6.1 EVENTS OF DEFAULT. In case one or more of the following
Events of Default (whatever the reason for such Event of Default and whether it
shall be voluntary or involuntary or be effected by operation of law or pursuant
to any judgment, decree or order of any court or any order, rule or regulation
of any administrative or governmental body) shall have occurred and be
continuing:

               (a) default in the payment of any installment of interest
(including Liquidated Damages Amount, if any) upon any of the Notes as and when
the same shall become due and payable, and continuance of such default for a
period of 30 days; or

               (b) default in the payment of the principal of or premium, if
any, on any of the Notes as and when the same shall become due and payable
either at maturity or in connection with any redemption or repurchase pursuant
to Article III, by acceleration or otherwise; or

               (c) failure on the part of the Company duly to observe or perform
any other of the covenants or agreements on the part of the Company in the Notes
or in this Indenture (other than a covenant or agreement a default in whose
performance or whose breach is elsewhere in this Section 6.1 specifically dealt
with) continued for a period of 60 days after the date on which written notice
of such failure, requiring the Company to remedy the same, shall have been given

                                       28
   36

to the Company by the Trustee, or the Company and a Responsible Officer of the
Trustee by the holders of at least 25% in aggregate principal amount of the
Notes at the time outstanding determined in accordance with Section 8.4; or

               (d) the Company or any Significant Subsidiary shall commence a
voluntary case or other proceeding seeking liquidation, reorganization or other
relief with respect to itself or any Significant Subsidiary or its or such
Significant Subsidiary's debts under any bankruptcy, insolvency or other similar
law now or hereafter in effect or seeking the appointment of a trustee,
receiver, liquidator, custodian or other similar official of it or any
Significant Subsidiary or any substantial part of the property of the Company or
any Significant Subsidiary, or shall consent to any such relief or to the
appointment of or taking possession by any such official in an involuntary case
or other proceeding commenced against it or any Significant Subsidiary, or shall
make a general assignment for the benefit of creditors, or shall fail generally
to pay its debts as they become due; or

               (e) an involuntary case or other proceeding shall be commenced
against the Company or any Significant Subsidiary seeking liquidation,
reorganization or other relief with respect to it or any Significant Subsidiary
or its or such Significant Subsidiary's debts under any bankruptcy, insolvency
or other similar law now or hereafter in effect or seeking the appointment of a
trustee, receiver, liquidator, custodian or other similar official of it or any
Significant Subsidiary or any substantial part of the property of the Company or
any Significant Subsidiary, and such involuntary case or other proceeding shall
remain undismissed and unstayed for a period of 90 consecutive days;

then, and in each and every such case (other than an Event of Default specified
in Section 6.1(d) or (e) with respect to the Company), unless the principal of
all of the Notes shall have already become due and payable, either the Trustee
or the holders of not less than 25% in aggregate principal amount of the Notes
then outstanding hereunder determined in accordance with Section 8.4, by notice
in writing to the Company (and to the Trustee if given by Noteholders), may
declare the principal of and premium, if any, on all the Notes and the interest
accrued thereon (including Liquidated Damages Amount, if any) to be due and
payable immediately, and upon any such declaration the same shall become and
shall be immediately due and payable, anything in this Indenture or in the Notes
contained to the contrary notwithstanding. If an Event of Default specified in
Section 6.1(d) or (e) with respect to the Company occurs, the principal of all
the Notes and the interest accrued thereon shall (including Liquidated Damages
Amount, if any) be immediately and automatically due and payable without
necessity of further action. This provision, however, is subject to the
conditions that if, at any time after the principal of the Notes shall have been
so declared due and payable, and before any judgment or decree for the payment
of the monies due shall have been obtained or entered as hereinafter provided,
the Company shall pay or shall deposit with the Trustee a sum sufficient to pay
all matured installments of interest upon (including Liquidated Damages Amount,
if any) all Notes and the principal of and premium, if any, on any and all Notes
which shall have become due otherwise than by acceleration (with interest on
overdue installments of interest (including Liquidated Damages Amount, if any)
(to the extent that payment of such interest is enforceable under applicable
law) and on such principal and premium, if any, at the rate borne by the Notes,
to the date of such payment or deposit) and amounts due to the Trustee pursuant
to Section 7.7, and if any and all defaults under this Indenture, other than the
nonpayment of principal of and premium, if any, and accrued interest on
(including Liquidated Damages Amount, if any) Notes

                                       29
   37

which shall have become due by acceleration, shall have been cured or waived
pursuant to Section 6.7, then and in every such case the holders of a majority
in aggregate principal amount of the Notes then outstanding, by written notice
to the Company and to the Trustee, may waive all defaults or Events of Default
and rescind and annul such declaration and its consequences; but no such waiver
or rescission and annulment shall extend to or shall affect any subsequent
default or Event of Default, or shall impair any right consequent thereon. The
Company shall notify a Responsible Officer of the Trustee, promptly (and in any
event within five Business Days) upon becoming aware thereof, of any Event of
Default.

          In case the Trustee shall have proceeded to enforce any right under
this Indenture and such proceedings shall have been discontinued or abandoned
because of such waiver or rescission and annulment or for any other reason or
shall have been determined adversely to the Trustee, then and in every such case
the Company, the holders of Notes, and the Trustee shall be restored
respectively to their several positions and rights hereunder, and all rights,
remedies and powers of the Company, the holders of Notes, and the Trustee shall
continue as though no such proceeding had been taken.

          SECTION 6.2 PAYMENTS OF NOTES ON DEFAULT; SUIT THEREFOR. The Company
covenants that (a) in case default shall be made in the payment of any
installment of interest upon (including Liquidated Damages Amount, if any) any
of the Notes as and when the same shall become due and payable, and such default
shall have continued for a period of 30 days, or (b) in case default shall be
made in the payment of the principal of or premium, if any, on any of the Notes
as and when the same shall have become due and payable, whether at maturity of
the Notes or in connection with any redemption or repurchase, upon a declaration
of acceleration or otherwise and upon demand of the Trustee, the Company will
pay to the Trustee, for the benefit of the holders of the Notes, the whole
amount that then shall have become due and payable on all such Notes for
principal and premium, if any, or interest (including Liquidated Damages Amount,
if any), as the case may be, with interest upon the overdue principal and
premium, if any, and (to the extent that payment of such interest is enforceable
under applicable law) upon the overdue installments of interest (including
Liquidated Damages Amount, if any) at the rate borne by the Notes; and, in
addition thereto, such further amount as shall be sufficient to cover the costs
and expenses of collection, including reasonable compensation to the Trustee,
its agents, attorneys and counsel, and all other amounts due the Trustee under
Section 7.7. Until such demand by the Trustee, the Company may pay the principal
of and premium, if any, and interest on (including Liquidated Damages Amount, if
any) the Notes to the registered holders, whether or not the Notes are overdue.

          In case the Company shall fail forthwith to pay such amounts upon
such demand, the Trustee, in its own name and as trustee of an express trust,
shall be entitled and empowered to institute any actions or proceedings at law
or in equity for the collection of the sums so due and unpaid, and may prosecute
any such action or proceeding to judgment or final decree, and may enforce any
such judgment or final decree against the Company or any other obligor on the
Notes and collect in the manner provided by law out of the property of the
Company or any other obligor on the Notes wherever situated the monies adjudged
or decreed to be payable.

          In case there shall be pending proceedings for the bankruptcy or for
the reorganization of the Company or any other obligor on the Notes under Title
11 of the United States Code, or any other applicable law, or in case a
receiver, assignee or trustee in bankruptcy or reorganization,

                                       30
   38

liquidator, sequestrator or similar official shall have been appointed for or
taken possession of the Company or such other obligor, the property of the
Company or such other obligor, or in the case of any other judicial proceedings
relative to the Company or such other obligor upon the Notes, or to the
creditors or property of the Company or such other obligor, the Trustee,
irrespective of whether the principal of the Notes shall then be due and payable
as therein expressed or by declaration or otherwise and irrespective of whether
the Trustee shall have made any demand pursuant to the provisions of this
Section 6.2, shall be entitled and empowered, by intervention in such
proceedings or otherwise, to file and prove a claim or claims for the whole
amount of principal, premium, if any, and interest (including Liquidated Damages
Amount, if any) owing and unpaid in respect of the Notes, and, in case of any
judicial proceedings, to file such proofs of claim and other papers or documents
as may be necessary or advisable in order to have the claims of the Trustee and
of the Noteholders allowed in such judicial proceedings relative to the Company
or any other obligor on the Notes, its or their creditors, or its or their
property, and to collect and receive any monies or other property payable or
deliverable on any such claims, and to distribute the same after the deduction
of any amounts due the Trustee under Section 7.7; and any receiver, assignee or
trustee in bankruptcy or reorganization, liquidator, custodian or similar
official is hereby authorized by each of the Noteholders to make such payments
to the Trustee, and, in the event that the Trustee shall consent to the making
of such payments directly to the Noteholders, to pay to the Trustee any amount
due it for reasonable compensation, expenses, advances and disbursements,
including counsel fees incurred by it up to the date of such distribution. To
the extent that such payment of reasonable compensation, expenses, advances and
disbursements out of the estate in any such proceedings shall be denied for any
reason, payment of the same shall be secured by a lien on, and shall be paid out
of, any and all distributions, dividends, monies, securities and other property
which the holders of the Notes may be entitled to receive in such proceedings,
whether in liquidation or under any plan of reorganization or arrangement or
otherwise.

          All rights of action and of asserting claims under this Indenture, or
under any of the Notes, may be enforced by the Trustee without the possession of
any of the Notes, or the production thereof at any trial or other proceeding
relative thereto, and any such suit or proceeding instituted by the Trustee
shall be brought in its own name as trustee of an express trust, and any
recovery of judgment shall, after provision for the payment of the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agent and
counsel, be for the ratable benefit of the holders of the Notes.

          In any proceedings brought by the Trustee (and in any proceedings
involving the interpretation of any provision of this Indenture to which the
Trustee shall be a party) the Trustee shall be held to represent all the holders
of the Notes, and it shall not be necessary to make any holders of the Notes
parties to any such proceedings.

          SECTION 6.3 APPLICATION OF MONIES COLLECTED BY TRUSTEE. Any monies
collected by the Trustee pursuant to this Article VI shall be applied in the
following order, at the date or dates fixed by the Trustee for the distribution
of such monies, upon presentation of the several Notes, and stamping thereon the
payment, if only partially paid, and upon surrender thereof, if fully paid:

               FIRST: To the payment of costs and expenses of collection,
          including all sums paid or advanced by the Trustee hereunder and the
          reasonable compensation, expenses

                                       31
   39

          and disbursements of the Trustee, its agents and counsel and all
          other amounts due the Trustee under Section 7.7;

               SECOND: In case the principal of the outstanding Notes shall not
          have become due and be unpaid, to the payment of interest on
          (including Liquidated Damages Amount, if any) the Notes in default in
          the order of the maturity of the installments of such interest, with
          interest (to the extent that such interest has been collected by the
          Trustee) upon the overdue installments of interest (including
          Liquidated Damages Amount, if any) at the rate borne by the Notes,
          such payments to be made ratably to the Persons entitled thereto;

               THIRD: In case the principal of the outstanding Notes shall have
          become due, by declaration or otherwise, and be unpaid to the payment
          of the whole amount then owing and unpaid upon the Notes for principal
          and premium, if any, and interest (including Liquidated Damages
          Amount, if any), with interest on the overdue principal and premium,
          if any, and (to the extent that such interest has been collected by
          the Trustee) upon overdue installments of interest (including
          Liquidated Damages Amount, if any) at the rate borne by the Notes; and
          in case such monies shall be insufficient to pay in full the whole
          amounts so due and unpaid upon the Notes, then to the payment of such
          principal and premium, if any, and interest (including Liquidated
          Damages Amount, if any) without preference or priority of principal
          and premium, if any, over interest (including Liquidated Damages
          Amount, if any), or of interest (including Liquidated Damages Amount,
          if any) over principal and premium, if any, or of any installment of
          interest over any other installment of interest, or of any Note over
          any other Note, ratably to the aggregate of such principal and
          premium, if any, and accrued and unpaid interest; and

               FOURTH: To the payment of the remainder, if any, to the Company
          or any other Person lawfully entitled thereto.

          SECTION 6.4 PROCEEDINGS BY NOTEHOLDER. No holder of any Note shall
have any right by virtue of or by availing of any provision of this Indenture to
institute any suit, action or proceeding in equity or at law upon or under or
with respect to this Indenture, or for the appointment of a receiver, trustee,
liquidator, custodian or other similar official, or for any other remedy
hereunder, unless such holder previously shall have given to the Trustee written
notice of an Event of Default and of the continuance thereof, as hereinbefore
provided, and unless also the holders of not less than 25% in aggregate
principal amount of the Notes then outstanding shall have made written request
upon the Trustee to institute such action, suit or proceeding in its own name as
Trustee hereunder and shall have offered to the Trustee such indemnity as it may
require against the costs, expenses and liabilities to be incurred therein or
thereby, and the Trustee for 60 days after its receipt of such notice, request
and offer of indemnity, shall have neglected or refused to institute any such
action, suit or proceeding and no direction inconsistent with such written
request shall have been given to the Trustee pursuant to Section 6.7; it being
understood and intended, and being expressly covenanted by the taker and holder
of every Note with every other taker and holder and the Trustee, that no one or
more holders of Notes shall have any right in any manner whatever by virtue of
or by availing of any provision of this Indenture to affect, disturb or
prejudice the rights of any other holder of Notes, or to obtain or seek to
obtain priority over or preference to any other such holder, or to enforce any
right under this Indenture, except in the manner herein provided and for the
equal, ratable and common benefit of all holders of Notes (except as otherwise
provided herein). For the

                                       32
   40

protection and enforcement of this Section 6.4, each and every Noteholder and
the Trustee shall be entitled to such relief as can be given either at law or in
equity.

          Notwithstanding any other provision of this Indenture and any
provision of any Note, the right of any holder of any Note to receive payment of
the principal of and premium, if any (including the redemption price or
repurchase price, if any, upon a redemption or a repurchase pursuant to Article
III), and accrued interest on (including Liquidated Damages Amount, if any) such
Note, on or after the respective due dates expressed in such Note or in the
event of redemption, or to institute suit for the enforcement of any such
payment on or after such respective dates against the Company shall not be
impaired or affected without the consent of such holder.

          Anything in this Indenture or the Notes to the contrary
notwithstanding, the holder of any Note, without the consent of either the
Trustee or the holder of any other Note, in its own behalf and for its own
benefit, may enforce, and may institute and maintain any proceeding suitable to
enforce, its rights of conversion as provided herein.

          SECTION 6.5 PROCEEDINGS BY TRUSTEE. In case of an Event of Default,
the Trustee may, in its discretion, proceed to protect and enforce the rights
vested in it by this Indenture by such appropriate judicial proceedings as are
necessary to protect and enforce any of such rights, either by suit in equity or
by action at law or by proceeding in bankruptcy or otherwise, whether for the
specific enforcement of any covenant or agreement contained in this Indenture or
in aid of the exercise of any power granted in this Indenture, or to enforce any
other legal or equitable right vested in the Trustee by this Indenture or by
law.

          SECTION 6.6 REMEDIES CUMULATIVE AND CONTINUING. Except as provided in
Section 2.6, all powers and remedies given by this Article VI to the Trustee or
to the Noteholders shall, to the extent permitted by law, be deemed cumulative
and not exclusive of any thereof or of any other powers and remedies available
to the Trustee or the holders of the Notes, by judicial proceedings or
otherwise, to enforce the performance or observance of the covenants and
agreements contained in this Indenture, and no delay or omission of the Trustee
or of any holder of any of the Notes to exercise any right or power accruing
upon any default or Event of Default occurring and continuing as aforesaid shall
impair any such right or power, or shall be construed to be a waiver of any such
default or any acquiescence therein; and, subject to the provisions of Section
6.4, every power and remedy given by this Article VI or by law to the Trustee or
to the Noteholders may be exercised from time to time, and as often as shall be
deemed expedient, by the Trustee or by the Noteholders.

          SECTION 6.7 DIRECTION OF PROCEEDINGS AND WAIVER OF DEFAULTS BY
MAJORITY OF NOTEHOLDERS. The holders of a majority in aggregate principal amount
of the Notes at the time outstanding determined in accordance with Section 8.4
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; 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 which is not inconsistent with such direction and
(iii) the Trustee may decline to take any action that would benefit any
Noteholder to the detriment of any other Noteholder. The holders of a majority
in aggregate principal amount of the Notes at the time outstanding determined in
accordance with Section 8.4 may, on behalf of the holders of all of the Notes,

                                       33
   41

waive any past default or Event of Default hereunder and its consequences except
(w) a default in the payment of interest (including Liquidated Damages Amount,
if any) or premium, if any, on, or the principal of, the Notes, (x) a failure by
the Company to convert any Notes into Common Stock, (y) a default in the payment
of the redemption price or repurchase price, if any, pursuant to Article III or
(z) a default in respect of a covenant or provisions hereof which under Article
X cannot be modified or amended without the consent of the holders of each or
all Notes then outstanding or affected thereby. Upon any such waiver, the
Company, the Trustee and the holders of the Notes shall be restored to their
former positions and rights hereunder; but no such waiver shall extend to any
subsequent or other default or Event of Default or impair any right consequent
thereon. Whenever any default or Event of Default hereunder shall have been
waived as permitted by this Section 6.7, said default or Event of Default shall
for all purposes of the Notes and this Indenture be deemed to have been cured
and to be not continuing; but no such waiver shall extend to any subsequent or
other default or Event of Default or impair any right consequent thereon.

          SECTION 6.8 UNDERTAKING TO PAY COSTS. All parties to this Indenture
agree, and each holder of any Note by his acceptance thereof shall be deemed to
have agreed, that any court may, in its discretion, require, in any suit for the
enforcement of any right or remedy under this Indenture, or in any suit against
the Trustee for any action taken 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; provided that the provisions of this Section 6.8
(to the extent permitted by law) shall not apply to any suit instituted by the
Trustee, to any suit instituted by any Noteholder, or group of Noteholders,
holding in the aggregate more than ten percent in principal amount of the Notes
at the time outstanding determined in accordance with Section 8.4, or to any
suit instituted by any Noteholder for the enforcement of the payment of the
principal of or premium, if any, or interest on any Note on or after the due
date expressed in such Note or to any suit for the enforcement of the right to
convert any Note in accordance with the provisions of Article XIV.

                                   ARTICLE VII

                             CONCERNING THE TRUSTEE

          SECTION 7.1 GENERAL. The duties and responsibilities of the Trustee
shall be as provided by the TIA and as set forth herein and no implied covenants
or obligations shall be read into this Indenture against the Trustee.
Notwithstanding the foregoing, no provision of this Indenture shall require the
Trustee to expend or risk its own funds or otherwise incur any financial
liability in the performance of any of its duties hereunder, or in the exercise
of any of its rights or powers, if it shall have reasonable grounds for
believing that repayment of such funds or adequate indemnity against such risk
or liability is not reasonably assured to it. Whether or not herein expressly so
provided, every provision of this Indenture relating to the conduct or affecting
the liability of or affording protection to the Trustee shall be subject to the
provisions of this Article VII.

          SECTION 7.2 CERTAIN RIGHTS OF TRUSTEE. Subject to TIA Sections 315(a)
through (d):

                                       34
   42

               (i) the Trustee may rely, and shall be protected in acting or
          refraining from acting, upon any resolution, certificate, statement,
          instrument, opinion, report, notice, request, direction, consent,
          order, bond, debenture, note, other evidence of indebtedness or other
          paper or document believed by it to be genuine and to have been signed
          or presented by the proper person. The Trustee need not investigate
          any fact or matter stated in any such document;

               (ii) before the Trustee acts or refrains from acting, it may
          require an Officers' Certificate or an Opinion of Counsel, which shall
          conform to Section 15.5. The Trustee shall not be liable for any
          action it takes or omits to take in good faith in reliance on such
          certificate or opinion;

               (iii) the Trustee may act through its attorneys and agents and
          shall not be responsible for the misconduct or negligence of any
          attorney or agent appointed with due care;

               (iv) the Trustee shall be under no obligation to exercise any of
          the rights or powers vested in it by this Indenture at the request or
          direction of any of the holders, unless such holders shall have
          offered to the Trustee reasonable security or indemnity against the
          costs, expenses and liabilities that might be incurred by it in
          compliance with such request or direction;

               (v) the Trustee shall not be liable for any action it takes or
          omits to take in good faith that it believes to be authorized or
          within its rights or powers or for any action it takes or omits to
          take in accordance with the written direction of the holders of a
          majority in principal amount of the outstanding Notes relating to the
          time, method and place of conducting any proceeding for any remedy
          available to the Trustee, or exercising any trust or power conferred
          upon the Trustee, under this Indenture;

               (vi) whenever in the administration of this Indenture the Trustee
          shall deem it desirable that a matter be proved or established prior
          to taking, suffering or omitting any action hereunder, the Trustee
          (unless other evidence be herein specifically prescribed) may, in the
          absence of bad faith on its part, rely upon an Officers' Certificate;

               (vii) the Trustee shall not be bound to make any investigation
          into the facts or matters stated in any resolution, certificate,
          statement, instrument, opinion, report, notice, request, direction,
          consent, order, bond, debenture, note, other evidence of indebtedness
          or other paper or document, but the Trustee, in its discretion, may
          make such further inquiry or investigation into such facts or matters
          as it may see fit, and, if the Trustee shall determine to make such
          further inquiry or investigation, it shall be entitled to examine the
          books, records and premises of the Company personally or by agent or
          attorney;

               (viii) the Trustee shall not be required to give any bond or
          surety in respect of the performance of its powers and duties
          hereunder;

                                       35
   43

               (ix) the Trustee shall not be bound to ascertain or inquire as to
          the performance or observance of any covenants, conditions or
          agreements on the part of the Company, except as otherwise set forth
          herein, but the Trustee may require of the Company full information
          and advice as to the performance of the covenants, conditions and
          agreements contained herein and shall be entitled in connection
          herewith to examine the books, records and premises of the Company;
          and

               (x) the permissive rights of the Trustee to do things enumerated
          in this Indenture shall not be construed as a duty and the Trustee
          shall not be answerable for other than its negligence or willful
          default.

          SECTION 7.3 INDIVIDUAL RIGHTS OF TRUSTEE. The Trustee, in its
individual or any other capacity, may become the owner or pledgee of Notes and
may otherwise deal with the Company or its Affiliates with the same rights it
would have if it were not the Trustee. Any registrar, co-registrar, paying
agent, conversion agent or authenticating agent may do the same with like
rights. However, the Trustee is subject to TIA Sections 310(b) and 311.

          SECTION 7.4 TRUSTEE'S DISCLAIMER. The Trustee (i) makes no
representation as to the validity or adequacy of this Indenture or the Notes,
(ii) shall not be accountable for the Company's use or application of the
proceeds from the Notes and (iii) shall not be responsible for any statement in
the Notes other than its certificate of authentication.

          SECTION 7.5 NOTICE OF DEFAULT. If any Default or any Event of Default
occurs and is continuing and if such Default or Event of Default is known to a
Responsible Officer of the Trustee, the Trustee shall mail to each holder in the
manner and to the extent provided in TIA Section 313(c) notice of the Default or
Event of Default within 45 days after it occurs, unless such Default or Event of
Default has been cured; provided, however, that, except in the case of a default
in the payment of the principal of, premium, if any, or interest (including
Liquidated Damages Amount, if any) on any Note, the Trustee shall be protected
in withholding such notice if and so long as the board of directors, the
executive committee or a trust committee of directors and/or Responsible
Officers of the Trustee in good faith determine that the withholding of such
notice is in the interest of the Noteholders.

          SECTION 7.6 CONFLICTING INTERESTS OF TRUSTEE. If the Trustee has or
shall acquire a conflicting interest within the meaning of the TIA, the Trustee
shall either eliminate such interest or resign, to the extent and in the manner
provided by, and subject to the provisions of the TIA and this Indenture.

          SECTION 7.7 COMPENSATION AND INDEMNITY. The Company shall pay to the
Trustee, and the Trustee will be entitled to, such compensation as shall be
agreed upon in writing for its services. The compensation of the Trustee shall
not be limited by any law on compensation of a trustee of an express trust. The
Company shall reimburse the Trustee upon request for all reasonable
out-of-pocket expenses and advances incurred or made by the Trustee. 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 losses,
liabilities, obligations, damages, penalties, judgments, actions, suits,
proceedings, reasonable costs and expenses (including reasonable fees and
disbursements of counsel) of any kind whatsoever which

                                       36
   44

may be incurred by the Trustee in connection with any investigative,
administrative or judicial proceeding (whether or not such indemnified party is
designated a party to such proceeding) arising out of or in connection with the
acceptance or administration of its duties under this Indenture; provided,
however, that the Company need not reimburse any expense or indemnify against
any loss, obligation, damage, penalty, judgment, action, suit, proceeding,
reasonable cost or expense (including reasonable fees and disbursements of
counsel) of any kind whatsoever which may be incurred by the Trustee in
connection with any investigative, administrative or judicial proceeding
(whether or not such indemnified party is designated a party to such proceeding)
in which it is determined that the Trustee acted with negligence, bad faith or
willful misconduct. The Trustee shall notify the Company promptly of any claim
for which it may seek indemnity. Failure by the Trustee to so notify the Company
shall not relieve the Company of its obligations hereunder, unless the Company
is materially prejudiced thereby. The Company shall defend the claim and the
Trustee shall cooperate in the defense. Unless otherwise set forth herein, the
Trustee may have separate counsel and the Company shall pay the reasonable fees
and expenses of such counsel. The Company need not pay for any settlement made
without its consent, which consent shall not be unreasonably withheld. The
obligations of the Company under this Section to compensate the Trustee, to pay
or reimburse the Trustee for expenses, disbursements and advances and to
indemnify and hold harmless the Trustee shall survive the satisfaction and
discharge of this Indenture and the resignation or removal of the Trustee.

          To secure the Company's payment obligations in this Section 7.7, the
Trustee shall have a lien prior to the Notes on all money or property held or
collected by the Trustee, in its capacity as Trustee, except money or property
held in trust to pay principal of, premium, if any, and interest on particular
Notes.

          If the Trustee incurs expenses or renders services after the
occurrence of an Event of Default specified in clause (d) or (e) of Section 6.1,
the expenses and the compensation for the services will be intended to
constitute expenses of administration under Title 11 of the United States
Bankruptcy Code or any applicable federal or state law for the relief of
debtors.

          SECTION 7.8 REPLACEMENT OF TRUSTEE. A resignation or removal of the
Trustee and appointment of a successor Trustee shall become effective only upon
the successor Trustee's acceptance of appointment as provided in this Section
7.8.

          The Trustee may resign at any time by so notifying the Company in
writing at least 30 days prior to the date of the proposed resignation. The
holders of a majority in principal amount of the outstanding Notes may remove
the Trustee by so notifying the Trustee in writing and may appoint a successor
Trustee with the consent of the Company. The Company may remove the Trustee if:
(i) the Trustee is no longer eligible under Section 7.10; (ii) the Trustee is
adjudged a bankrupt or an insolvent; (iii) a receiver or other public officer
takes charge of the Trustee or its property; or (iv) the Trustee becomes
incapable of acting.

          If the Trustee resigns or is removed, or if a vacancy exists in the
office of Trustee for any reason, the Company shall promptly appoint a successor
Trustee. Within one year after the successor Trustee takes office, the holders
of a majority in principal amount of the outstanding Notes may appoint a
successor Trustee to replace the successor Trustee appointed by the Company. If
the successor Trustee does not deliver its written acceptance required by the
next succeeding paragraph of this Section 7.8 within 30 days after the retiring
Trustee resigns or is

                                       37
   45

removed, the retiring Trustee, the Company or the holders of a majority in
principal amount of the outstanding Notes may petition any court of competent
jurisdiction for the appointment of a successor Trustee.

          A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Company. Immediately after the
delivery of such written acceptance, subject to the lien provided in Section
7.7, (i) the retiring Trustee shall transfer all property held by it as Trustee
to the successor Trustee, (ii) the resignation or removal of the retiring
Trustee shall become effective and (iii) the successor Trustee shall have all
the rights, powers and duties of the Trustee under this Indenture. A successor
Trustee shall mail notice of its succession to each holder.

          If the Trustee is no longer eligible under Section 7.10, any holder
who satisfies the requirements of TIA Section 310(b) may petition any court of
competent jurisdiction for the removal of the Trustee and the appointment of a
successor Trustee.

          The Company shall give notice of any resignation and any removal of
the Trustee and each appointment of a successor Trustee to all holders. Each
notice shall include the name of the successor Trustee and the address of its
Corporate Trust Office.

          Notwithstanding replacement of the Trustee pursuant to this Section
7.8, the Company's obligation under Section 7.7 shall continue for the benefit
of the retiring Trustee.

          SECTION 7.9 SUCCESSOR TRUSTEE BY MERGER, ETC. If the Trustee
consolidates with, merges or converts into, or transfers all or substantially
all of its corporate trust business to, another corporation or national banking
association, the resulting, surviving or transferee corporation or national
banking association without any further act shall be the successor Trustee with
the same effect as if the successor Trustee had been named as the Trustee
herein.

          SECTION 7.10 ELIGIBILITY. This Indenture shall always have a Trustee
who satisfies the requirements of TIA Section 310(a)(1) and (5). The Trustee (or
the bank holding company to which the Trustee is a member) shall have a combined
capital and surplus of at least $25 million as set forth in its most recent
published annual report of condition.

          SECTION 7.11 MONEY HELD IN TRUST. Subject to the provisions of
Section 12.4, all monies received by the Trustee shall, until used or applied as
herein provided, be held in trust for the purposes for which they were received.
The Trustee shall not be liable for interest on any money received by it except
as the Trustee may agree with the Company. Money held in trust by the Trustee
need not be segregated from other funds except to the extent required by law and
except for money held in trust under Article XII of this Indenture.

          SECTION 7.12 WITHHOLDING TAXES. The Trustee, as agent for the
Company, shall exclude and withhold from each payment of principal and interest
and other amounts due hereunder or under the Notes any and all withholding taxes
applicable thereto as required by law. The Trustee agrees to act as such
withholding agent and, in connection therewith, whenever any present or future
taxes or similar charges are required to be withheld with respect to any amounts
payable in respect of the Notes, to withhold such amounts and timely pay the
same to the appropriate authority in the name of and on behalf of the holders of
the Notes, that it will file any

                                       38
   46

necessary withholding tax returns or statements when due, and that, as promptly
as possible after the payment thereof, it will deliver to each holder of a Note
appropriate documentation showing the payment thereof, together with such
additional documentary evidence as such holders may reasonably request from time
to time.

          SECTION 7.13 PREFERENTIAL COLLECTION OF CLAIMS. If and when the
Trustee shall be or become a creditor of the Company (or any other obligor upon
the Notes), the Trustee shall be subject to the provisions of the Trust
Indenture Act regarding the collection of the claims against the Company (or any
such other obligor).

          SECTION 7.14 TRUSTEE'S APPLICATION FOR INSTRUCTIONS FROM THE COMPANY.
Any application by the Trustee for written instructions from the Company (other
than with regard to any action proposed to be taken or omitted to be taken by
the Trustee that affects the rights of the holders of the Notes under this
Indenture) may, at the option of the Trustee, set forth in writing any action
proposed to be taken or omitted by the Trustee under this Indenture and the date
on and/or after which such action shall be taken or such omission shall be
effective. The Trustee shall not be liable for any action taken by, or omission
of, the Trustee in accordance with a proposal included in such application on or
after the date specified in such application (which date shall not be less than
three Business Days after the date any officer of the Company actually receives
such application, unless any such officer shall have consented in writing to any
earlier date) unless prior to taking any such action (or the effective date in
the case of an omission), the Trustee shall have received written instructions
in response to such application specifying the action to be taken or omitted.

                                  ARTICLE VIII

                           CONCERNING THE NOTEHOLDERS

          SECTION 8.1 ACTION BY NOTEHOLDERS. Whenever in this Indenture it is
provided that the holders of a specified percentage in aggregate principal
amount of the Notes may take any action (including the making of any demand or
request, the giving of any notice, consent or waiver or the taking of any other
action), the fact that at the time of taking any such action, the holders of
such specified percentage have joined therein may be evidenced (a) by any
instrument or any number of instruments of similar tenor executed by Noteholders
in person or by agent or proxy appointed in writing, or (b) by the record of the
holders of Notes voting in favor thereof at any meeting of Noteholders duly
called and held in accordance with the provisions of Article IX, or (c) by a
combination of such instrument or instruments and any such record of such a
meeting of Noteholders. Whenever the Company or the Trustee solicits the taking
of any action by the holders of the Notes, the Company or the Trustee may fix in
advance of such solicitation, a date as the record date for determining holders
entitled to take such action (except that in respect of any amended consent
solicitation, the record date in respect of such amended consent solicitation
may be the same as the record date of the original consent solicitation). The
record date shall be not more than 15 days prior to the date of commencement of
solicitation of such action.

          SECTION 8.2 PROOF OF EXECUTION BY NOTEHOLDERS. Subject to the
provisions of Sections 7.1, 7.2 and 9.5, proof of the execution of any
instrument by a Noteholder or its agent or proxy shall be sufficient if made in
accordance with such reasonable rules and regulations as may

                                       39
   47

be prescribed by the Trustee or in such manner as shall be satisfactory to the
Trustee. The holding of Notes shall be proved by the Note register or by a
certificate of the Note registrar.

          The record of any Noteholders' meeting shall be proved in the manner
provided in Section 9.6.

          SECTION 8.3 WHO ARE DEEMED ABSOLUTE OWNERS. The Company, the Trustee,
any paying agent, any conversion agent and any Note registrar may deem the
Person in whose name such Note shall be registered upon the Note register to be,
and may treat it as, the absolute owner of such Note (whether or not such Note
shall be overdue and notwithstanding any notation of ownership or other writing
thereon) for the purpose of receiving payment of or on account of the principal
of, premium, if any, and interest on such Note, for conversion of such Note and
for all other purposes; and neither the Company nor the Trustee nor any paying
agent nor any conversion agent nor any Note registrar shall be affected by any
notice to the contrary. All such payments so made to any holder for the time
being, or upon his order, shall be valid, and, to the extent of the sum or sums
so paid, effectual to satisfy and discharge the liability for monies payable
upon any such Note.

          SECTION 8.4 COMPANY-OWNED NOTES DISREGARDED. In determining whether
the holders of the requisite aggregate principal amount of Notes have concurred
in any direction, consent, waiver or other action under this Indenture, Notes
which are owned by the Company or any other obligor on the Notes or any
Affiliate of the Company or any other obligor on the Notes shall be disregarded
and deemed not to be outstanding for the purpose of any such determination;
provided that, for the purposes of determining whether the Trustee shall be
protected in relying on any such direction, consent, waiver or other action,
only Notes which a Responsible Officer knows are so owned shall be so
disregarded. Notes so owned which have been pledged in good faith may be
regarded as outstanding for the purposes of this Section 8.4 if the pledgee
shall establish to the satisfaction of the Trustee the pledgee's right to vote
such Notes and that the pledgee is not the Company, any other obligor on the
Notes or any Affiliate of the Company or any such other obligor. In the case of
a dispute as to such right, any decision by the Trustee taken upon the advice of
counsel shall be full protection to the Trustee. Upon request of the Trustee,
the Company shall furnish to the Trustee promptly an Officers' Certificate
listing and identifying all Notes, if any, known by the Company to be owned or
held by or for the account of any of the above described Persons; and, subject
to Section 7.1, the Trustee shall be entitled to accept such Officers'
Certificate as conclusive evidence of the facts therein set forth and of the
fact that all Notes not listed therein are outstanding for the purpose of any
such determination.

          SECTION 8.5 REVOCATION OF CONSENTS; FUTURE HOLDERS BOUND. At any time
prior to (but not after) the evidencing to the Trustee, as provided in Section
8.1, of the taking of any action by the holders of the percentage in aggregate
principal amount of the Notes specified in this Indenture in connection with
such action, any holder of a Note which is shown by the evidence to be included
in the Notes the holders of which have consented to such action may, by filing
written notice with the Trustee at its Corporate Trust Office and upon proof of
holding as provided in Section 8.2, revoke such action so far as concerns such
Note. Except as aforesaid, any such action taken by the holder of any Note shall
be conclusive and binding upon such holder and upon all future holders and
owners of such Note and of any Notes issued in exchange or substitution
therefor, irrespective of whether any notation in regard thereto is made upon
such Note or any Note issued in exchange or substitution therefor.

                                       40
   48

                                   ARTICLE IX

                              NOTEHOLDERS' MEETINGS

           SECTION 9.1 PURPOSE OF MEETINGS. A meeting of Noteholders may be
called at any time and from time to time pursuant to the provisions of this
Article IX for any of the following purposes:

                    (1) to give any notice to the Company or to the Trustee or

                    (2) to remove the Trustee and nominate a successor trustee

                    (4) to take any other action authorized to be taken by or on
behalf of the holders of any specified aggregate principal amount of the Notes
under any other provision of this Indenture or under applicable law.

Nothing in this Article IX imposes any limitation on the Company's ability to
solicit the Noteholders' taking any action (including, without limitation, the
actions in clauses (1) through (4) above) without a meeting in accordance with
Article VIII.

          SECTION 9.2 CALL OF MEETINGS BY TRUSTEE. The Trustee may at any time
call a meeting of Noteholders to take any action specified in Section 9.1, to be
held at such time and at such place as the Trustee shall determine. Notice of
every meeting of the Noteholders, setting forth the time and the place of such
meeting and in general terms the action proposed to be taken at such meeting and
the establishment of any record date pursuant to Section 8.1, shall be mailed at
the expense of the Company to holders of Notes at their addresses as they shall
appear on the Note register. Such notice shall also be mailed to the Company.
Such notices shall be mailed not less than 20 nor more than 90 days prior to the
date fixed for the meeting.

          Any meeting of Noteholders shall be valid without notice if the
holders of all Notes then outstanding are present in person or by proxy or if
notice is waived before or after the meeting by the holders of all Notes
outstanding, and if the Company and the Trustee are either present by duly
authorized representatives or have, before or after the meeting, waived notice.

          SECTION 9.3 CALL OF MEETINGS BY COMPANY OR NOTEHOLDERS. In case (x) at
any time the Company, pursuant to a resolution of its Board of Directors, (y) at
any time when a Default or Event of Default has occurred and is continuing, the
holders of at least 10% in aggregate principal amount of the Notes then
outstanding or (z) the holders of at least 25% in aggregate principal amount of
the Notes then outstanding, shall have requested the Trustee to call a meeting

                                       41
   49

of Noteholders, by written request setting forth in reasonable detail the action
proposed to be taken at the meeting, and the Trustee shall not have mailed the
notice of such meeting within 20 days after receipt of such request, then the
Company or such Noteholders may determine the time and the place for such
meeting and may call such meeting to take any action authorized in Section 9.1,
by mailing notice thereof as provided in Section 9.2.

          SECTION 9.4 QUALIFICATIONS FOR VOTING. To be entitled to vote at any
meeting of Noteholders a person shall (a) be a holder of one or more Notes on
the record date pertaining to such meeting or (b) be a person appointed by an
instrument in writing as proxy by a holder of one or more Notes on the record
date pertaining to such meeting. The only persons who shall be entitled to be
present or to speak at any meeting of Noteholders shall be the persons entitled
to vote at such meeting and their counsel and any representatives of the Trustee
and its counsel and any representatives of the Company and its counsel.

          SECTION 9.5 REGULATIONS. Notwithstanding any other provisions of this
Indenture, the Trustee may make such reasonable regulations as it may deem
advisable for any meeting of Noteholders, in regard to proof of the holding of
Notes and of the appointment of proxies, and in regard to the appointment and
duties of inspectors of votes, the submission and examination of proxies,
certificates and other evidence of the right to vote, and such other matters
concerning the conduct of the meeting as it shall think fit.

          The Trustee shall, by an instrument in writing, appoint a temporary
chairman of the meeting, unless the meeting shall have been called by the
Company or by Noteholders as provided in Section 9.3, in which case the Company
or the Noteholders calling the meeting, as the case may be, shall in like manner
appoint a temporary chairman. A permanent chairman and a permanent secretary of
the meeting shall be elected by vote of the holders of a majority in principal
amount of the Notes represented at the meeting and entitled to vote at the
meeting.

          Subject to the provisions of Section 8.4, at any meeting each
Noteholder or proxyholder shall be entitled to one vote for each $1,000
principal amount of Notes held or represented by him; provided, however, that no
vote shall be cast or counted at any meeting in respect of any Note challenged
as not outstanding and ruled by the chairman of the meeting to be not
outstanding. The chairman of the meeting shall have no right to vote other than
by virtue of Notes held by him or instruments in writing as aforesaid duly
designating him as the proxy to vote on behalf of other Noteholders. Any meeting
of Noteholders duly called pursuant to the provisions of Section 9.2 or 9.3 may
be adjourned from time to time by the holders of a majority of the aggregate
principal amount of Notes represented at the meeting, whether or not
constituting a quorum, and the meeting may be held as so adjourned without

the meeting and there shall be attached to said record the original reports of
the inspectors of votes on any vote by ballot taken thereat and

verified by the affidavits of the permanent chairman and secretary of the
meeting and one of the duplicates shall be delivered to the Company and the
other to the Trustee to be preserved by the Trustee, the latter to have attached
thereto the ballots voted at the meeting.

          Any record so signed and verified shall be conclusive evidence of the
matters therein stated.

          SECTION 9.7 EXERCISE OF RIGHTS OF TRUSTEE OR NOTEHOLDERS MAY NOT BE
HINDERED OR DELAYED BY CALL OF MEETING. Nothing contained in this Article IX
will be deemed or construed to authorize or permit, by reason of any call of a
meeting of Noteholders or any rights expressly or impliedly conferred hereunder
to make such call, any hindrance or delay in the exercise of any right or rights
conferred upon or reserved to the Trustee or to the Noteholders under any of the
provisions of this Indenture or the Notes.

          SECTION 9.8 PROCEDURES NOT EXCLUSIVE. The procedures set forth in
this Article IX are not exclusive and the rights and obligations of the Company,
the Trustee and the Noteholders under other Articles of this Indenture will in
no way be limited by the provisions of this Article IX.

supplemental hereto for one or more of the following purposes:

                    (a) to make provision with respect to the conversion rights
of the holders of Notes pursuant to the requirements of Section 14.6 and the
repurchase obligations of the Company pursuant to the requirements of Section
3.5(e);

                    (b) to convey, transfer, assign, mortgage or pledge to the
Trustee as security for the Notes, any property or assets;

                    (c) to evidence the succession of another Person to the
Company, or successive successions, and the assumption by the successor Person
of the covenants, agreements and obligations of the Company pursuant to Article
XI;

                    (d) to add to the covenants of the Company such further
covenants, restrictions or conditions, or grant to the Noteholders such other or
further rights, as the Board of Directors and the Trustee shall consider to be
for the benefit of the holders of Notes, and to make the occurrence, or the
occurrence and continuance, of a default in any such additional covenants,

                                       43
   51

restrictions or conditions a default or an Event of Default permitting the
enforcement of all or any of the several remedies provided in this Indenture as
herein set forth; provided, however, that in respect of any such additional
covenant, restriction or condition, such supplemental indenture may provide for
a particular period of grace after default (which period may be shorter or
longer than that allowed in the case of other defaults), procedures or
requirements relating to the waiver of such default (which procedures or
requirements may be more or less stringent than those applicable in the case of
other defaults) or may provide for an immediate enforcement upon such default or
may limit the remedies available to the Trustee upon such default;

                    (e) to provide for the issuance under this Indenture of
Notes in coupon form (including Notes registrable as to principal only) and to
provide for exchangeability of such Notes with the Notes issued hereunder in
fully registered form and to make all appropriate changes for such purpose;

                    (f) to cure any ambiguity or to correct or supplement any
provision contained herein or in any supplemental indenture that may be
defective or inconsistent with any other provision contained herein or in any
supplemental indenture, or to make such other provisions in regard to matters or
questions arising under this Indenture that shall not materially adversely
affect the interests of the holders of the Notes (as determined in good faith by
the Board of Directors);

                    (g) to evidence and provide for the acceptance of
appointment hereunder by a successor Trustee with respect to the Notes; or

Indenture to such extent as shall be necessary to effect the qualifications of
this Indenture under the Trust Indenture Act, or under any similar federal
statute hereafter enacted.

          Upon the written request of the Company, accompanied by a copy of the
resolutions of the Board of Directors certified by its Secretary or Assistant
Secretary authorizing the execution of any supplemental indenture, the Trustee
is hereby authorized to join with the Company in the execution of any such
supplemental indenture, to make any further appropriate agreements and
stipulations that may be therein contained and to accept the conveyance,
transfer and assignment of any property thereunder, but the Trustee shall not be
obligated to, but may in its discretion, enter into any supplemental indenture
that affects the Trustee's own rights, duties or immunities under this Indenture
or otherwise.

          Any supplemental indenture authorized by the provisions of this
Section 10.1 may be executed by the Company and the Trustee without the consent
of the holders of any of the Notes at the time outstanding, notwithstanding any
of the provisions of Section 10.2.

          Notwithstanding any other provision of the Indenture or the Notes,
the Registration Rights Agreement and the obligation to pay Liquidated Damages
Amount thereunder may be amended, modified or waived in accordance with the
provisions of the Registration Rights Agreement.

          SECTION 10.2 SUPPLEMENTAL INDENTURE WITH CONSENT OF NOTEHOLDERS. With
the consent (evidenced as provided in Article VIII) of the holders of not less
than a majority in

                                       44
   52

aggregate principal amount of the Notes at the time outstanding, the Company,
when authorized by the resolutions of the Board of Directors, and the Trustee
may, from time to time and at any time, enter into an indenture or indentures
supplemental hereto for the purpose of adding any provisions to or changing in
any manner or eliminating any of the provisions of this Indenture or any
supplemental indenture or of modifying in any manner the rights of the holders
of the Notes; provided, however, that no such supplemental indenture shall (i)
extend the fixed maturity of any Note, or reduce the interest rate or extend the
time for payment of interest thereon, or reduce the principal amount thereof or
premium, if any, thereon, or reduce any amount payable on redemption or
repurchase thereof, or impair the right of any Noteholder to institute suit for
the payment thereof, or make the principal thereof or interest or premium, if
any, thereon payable in any coin or currency other than that provided in the
Notes, or after the occurrence of a Fundamental Change, and subject to the terms
of Section 3.5(g), change the obligation of the Company to repurchase any Note
because of that Fundamental Change in a manner adverse to the holder of Notes,
or impair the right to convert the Notes into Common Stock subject to the terms
set forth herein, including Section 14.6, in each case, without the consent of
the holder of each Note so affected, or (ii) reduce the aforesaid percentage of
Notes, the holders of which are required to consent to any such supplemental
indenture, without the consent of the holders of all Notes then outstanding and
further, provided, that this Section 10.2 shall not preclude the right of the
Noteholders to waive a default specified in Section 6.1(a) or Section 6.1(b) of
this Indenture in accordance with the provisions of Section 6.1.

          Upon the written request of the Company, accompanied by a copy of the
resolutions of the Board of Directors certified by its Secretary or Assistant
Secretary and authorizing the execution of any such supplemental indenture, and
upon the filing with the Trustee of evidence of the consent of Noteholders as
aforesaid, the Trustee shall join with the Company in the execution of such
supplemental indenture unless such supplemental indenture affects the Trustee's
own rights, duties or immunities under this Indenture or otherwise, in which
case the Trustee may in its discretion, but shall not be obligated to, enter
into such supplemental indenture.

          It shall not be necessary for the consent of the Noteholders under
this Section 10.2 to approve the particular form of any proposed supplemental
indenture, but it shall be sufficient if such consent shall approve the
substance thereof.

          SECTION 10.3 EFFECT OF SUPPLEMENTAL INDENTURE. Any supplemental
indenture executed pursuant to the provisions of this Article X shall comply
with the Trust Indenture Act, as then in effect, provided that this Section 10.3
shall not require such supplemental indenture or the Trustee to be qualified
under the Trust Indenture Act prior to the time such qualification is in fact
required under the terms of the Trust Indenture Act or the Indenture has been
qualified under the Trust Indenture Act, nor shall it constitute any admission
or acknowledgment by any party to such supplemental indenture that any such
qualification is required prior to the time such qualification is in fact
required under the terms of the Trust Indenture Act or the Indenture has been
qualified under the Trust Indenture Act. Upon the execution of any supplemental
indenture pursuant to the provisions of this Article X, this Indenture shall be
and be deemed to be modified and amended in accordance therewith and the
respective rights, limitation of rights, obligations, duties and immunities
under this Indenture of the Trustee, the Company and the holders of Notes
shall thereafter be determined, exercised and enforced hereunder, subject in all
respects to such modifications and amendments and all the term and conditions of
any such supplemental

                                       45
   53

indenture shall be and be deemed to be part of the terms and conditions of this
Indenture for any and all purposes.

          SECTION 10.4 NOTATION ON NOTES. Notes authenticated and delivered
after the execution of any supplemental indenture pursuant to the provisions of
this Article X may bear a notation in form approved by the Trustee as to any
matter provided for in such supplemental indenture. If the Company or the
Trustee shall so determine, new Notes so modified as to conform, in the opinion
of the Trustee and the Board of Directors, to any modification of this Indenture
contained in any such supplemental indenture may, at the Company's expense, be
prepared and executed by the Company, authenticated by the Trustee (or an
authenticating agent duly appointed by the Trustee pursuant to Section 15.11)
and delivered in exchange for the Notes then outstanding, upon surrender of such
Notes then outstanding.

          SECTION 10.5 EVIDENCE OF COMPLIANCE OF SUPPLEMENTAL INDENTURE TO BE
FURNISHED TO TRUSTEE. Prior to entering into any supplemental indenture, the
Trustee may request an Officers' Certificate and an Opinion of Counsel meeting
the requirements set forth in Section 15.5 as conclusive evidence that any
supplemental indenture executed pursuant hereto complies with the requirements
of this Article X. The Opinion of Counsel shall also state that the Supplemental
Indenture will be valid and binding upon the Company, subject to customary
exceptions.

                                   ARTICLE XI

                CONSOLIDATION, MERGER, SALE, CONVEYANCE AND LEASE

          SECTION 11.1 COMPANY MAY CONSOLIDATE, ETC., ON CERTAIN TERMS. Subject
to the provisions of Section 11.2, nothing contained in this Indenture or in any
of the Notes shall prevent any consolidation or merger of the Company with or
into any other Person or Persons (whether or not affiliated with the Company),
or successive consolidations or mergers in which the Company or its successor or
successors shall be a party or parties, or shall prevent any sale, conveyance or
lease (or successive sales, conveyances or leases) of all or substantially all
of the property of the Company, to any other Person (whether or not affiliated
with the Company), authorized to acquire and operate the same and that shall be
organized under the laws of the United States of America, any state thereof or
the District of Columbia; provided that upon any such consolidation, merger,
sale, conveyance or lease, the due and punctual payment of the principal of and
premium, if any, and interest (including Liquidated Damages Amount, if any) on
all of the Notes, according to their tenor and the due and punctual performance
and observance of all of the covenants and conditions of this Indenture to be
performed by the Company, shall be expressly assumed, by supplemental indenture
satisfactory in form to the Trustee, executed and delivered to the Trustee by
the Person (if other than the Company) formed by such consolidation, or into
which the Company shall have been merged, or by the Person that shall have
acquired or leased such property, and such supplemental indenture shall provide
for the applicable conversion rights set forth in Section 14.6.

          SECTION 11.2 SUCCESSOR CORPORATION TO BE SUBSTITUTED. In case of any
such consolidation, merger, sale, conveyance or lease and upon the assumption by
the successor Person, by supplemental indenture, executed and delivered to the
Trustee and satisfactory in

                                       46
   54

form to the Trustee, of the due and punctual payment of the principal of and
premium, if any, and interest on all of the Notes and the due and punctual
performance of all of the covenants and conditions of this Indenture to be
performed by the Company, such successor Person shall succeed to and be
substituted for the Company, with the same effect as if it had been named herein
as the Company. Such successor Person thereupon may cause to be signed, and may
issue either in its own name or in the name of Nextel Communications, Inc. any
or all of the Notes, issuable hereunder that theretofore shall not have been
signed by the Company and delivered to the Trustee; and, upon the order of such
successor Person instead of the Company and subject to all the terms, conditions
and limitations in this Indenture prescribed, the Trustee shall authenticate and
shall deliver, or cause to be authenticated and delivered, any Notes that
previously shall have been signed and delivered by the officers of the Company
to the Trustee for authentication, and any Notes that such successor Person
thereafter shall cause to be signed and delivered to the Trustee for that
purpose. All the Notes so issued shall in all respects have the same legal rank
and benefit under this Indenture as the Notes theretofore or thereafter issued
in accordance with the terms of this Indenture as though all of such Notes had
been issued at the date of the execution hereof. In the event of any such
consolidation, merger, sale, conveyance or lease, the Person named as the
"Company" in the first paragraph of this Indenture or any successor that shall
thereafter have become such in the manner prescribed in this Article XI may be
dissolved, wound up and liquidated at any time thereafter and such Person shall
be released from its liabilities as obligor and maker of the Notes and from its
obligations under this Indenture.

          In case of any such consolidation, merger, sale, conveyance or lease,
such changes in phraseology and form (but not in substance) may be made in the
Notes thereafter to be issued as may be appropriate.

          SECTION 11.3 OPINION OF COUNSEL TO BE GIVEN TRUSTEE. The Trustee
shall receive an Officers' Certificate and an Opinion of Counsel as conclusive
evidence that any such consolidation, merger, sale, conveyance or lease and any
such assumption complies with the provisions of this Article XI.

                                       47

                                   ARTICLE XII

                     SATISFACTION AND DISCHARGE OF INDENTURE

          SECTION 12.1 DISCHARGE OF INDENTURE. When (a) the Company shall
deliver to the Trustee for cancellation all Notes theretofore authenticated
(other than any Notes that have been destroyed, lost or stolen and in lieu of or
in substitution for which other Notes shall have been authenticated and
delivered) and not theretofore canceled, or (b) all the Notes not theretofore
canceled or delivered to the Trustee for cancellation shall have become due and
payable, or are by their terms to become due and payable within one year or are
to be called for redemption within one year under arrangements satisfactory to
the Trustee for the giving of notice of redemption, and the Company shall
deposit with the Trustee, in trust, funds sufficient to pay at maturity or upon
redemption of all of the Notes (other than any Notes that shall have been
mutilated, destroyed, lost or stolen and in lieu of or in substitution for which
other Notes shall have been authenticated and delivered) not theretofore
canceled or delivered to the Trustee for cancellation, including principal and
premium, if any, and interest due or to become due to such date of maturity or
redemption date, as the case may be, accompanied by a verification report, as to
the sufficiency of the deposited amount, from an independent certified
accountant or other financial professional satisfactory to the Trustee, and if
the Company shall also pay or cause to be paid all other sums payable hereunder
by the Company, then this Indenture and the Notes shall cease to be of further
effect (except as to (i) remaining rights of registration of transfer,
substitution and exchange and conversion of Notes, (ii) rights hereunder of
Noteholders to receive payments of principal of and premium, if any, and
interest on, the Notes and the other rights, duties and obligations of
Noteholders, as beneficiaries hereof, in each case, solely with respect to the
amounts, so deposited with the Trustee and (iii) the rights, obligations and
immunities of the Trustee hereunder), and the Trustee, on written demand of the
Company accompanied by an Officers' Certificate and an Opinion of Counsel as
required by Section 15.5 and at the cost and expense of the Company, shall
execute proper instruments acknowledging satisfaction of and discharging this
Indenture; the Company, however, hereby agreeing to reimburse the Trustee for
any costs or expenses thereafter reasonably and properly incurred by the Trustee
and to compensate the Trustee for any services thereafter reasonably and
properly rendered by the Trustee in connection with this Indenture or the Notes.

          SECTION 12.2 DEPOSITED MONIES TO BE HELD IN TRUST BY TRUSTEE. Subject
to Section 12.4, all monies deposited with the Trustee pursuant to Section 12.1
shall be held in trust for the sole benefit of the Noteholders and such monies
shall be applied by the Trustee to the payment, either directly or through any
paying agent (including the Company if acting as its own paying agent), to the
holders of the particular Notes for the payment or redemption of which such
monies have been deposited with the Trustee, of all sums due and to become due
thereon for principal and interest and premium, if any.

          SECTION 12.3 PAYING AGENT TO REPAY MONIES HELD. Upon the satisfaction
and discharge of this Indenture, all monies then held by any paying agent of the
Notes (other than the Trustee) shall, upon written request of the Company set
forth in an Officer's Certificate, be repaid to it or paid to the Trustee, and
thereupon such paying agent shall be released from all further liability with
respect to such monies.

          SECTION 12.4 RETURN OF UNCLAIMED MONIES. Subject to the requirements
of applicable law, any monies deposited with or paid to the Trustee for payment
of the principal of, premium,

                                       48
   56

if any, or interest on Notes and not applied but remaining unclaimed by the
holders of Notes for two years after the date upon which the principal of,
premium, if any, or interest on such Notes, as the case may be, shall have
become due and payable, shall be repaid to the Company by the Trustee on demand
and all liability of the Trustee shall thereupon cease with respect to such
monies; and the holder of any of the Notes shall thereafter look only to the
Company for any payment that such holder may be entitled to collect unless an
applicable abandoned property law designates another Person. Notwithstanding the
foregoing, this Section 12.4 shall not be applicable to monies deposited with or
paid to the Trustee in respect of any holder of Notes to the extent any such
holder is no longer entitled to the receipt of any such monies, and the Trustee
shall repay any such monies to the Company on demand.

          SECTION 12.5 REINSTATEMENT. If the Trustee or the paying agent is
unable to apply any money in accordance with Section 12.2 by reason of any order
or judgment of any court or governmental authority enjoining, restraining or
otherwise prohibiting such application, the Company's obligations under this
Indenture and the Notes shall be revived and reinstated as though no deposit had
occurred pursuant to Section 12.1 until such time as the Trustee or the paying
agent is permitted to apply all such money in accordance with Section 12.2;
provided, however, that if the Company makes any payment of interest on or
principal of any Note following the reinstatement of its obligations, the
Company shall be subrogated to the rights of the holders of such Notes to
receive such payment from the money held by the Trustee or paying agent.

                                  ARTICLE XIII

         IMMUNITY OF INCORPORATORS, STOCKHOLDERS, OFFICERS AND DIRECTORS

          SECTION 13.1 INDENTURE AND NOTES SOLELY CORPORATE OBLIGATIONS. No
recourse for the payment of the principal of or premium, if any, or interest on
any Note, or for any claim based thereon or otherwise in respect thereof, and no
recourse under or upon any obligation, covenant or agreement of the Company in
this Indenture or in any supplemental indenture or in any Note, or because of
the creation of any indebtedness represented thereby, shall be had against any
incorporator, stockholder, employee, agent, officer, director or subsidiary, as
such, past, present or future, of the Company or of any successor corporation,
either directly or through the Company or any successor corporation, whether by
virtue of any constitution, statute or rule of law, or by the enforcement of any
assessment or penalty or otherwise; it being expressly understood that all such
liability is hereby expressly waived and released as a condition of, and as a
consideration for, the execution of this Indenture and the issue of the Notes.

   57

                                   ARTICLE XIV

                               CONVERSION OF NOTES

          SECTION 14.1 RIGHT TO CONVERT. Subject to and upon compliance with
the provisions of this Indenture, the holder of any Note shall have the right,
at its option, at any time after the original issuance of the Notes hereunder
through the close of business on the Business Day prior to the date of
repurchase, redemption or final maturity of the Notes (except as provided in
Section 3.4 and except that, with respect to any Note or portion of a Note that
shall be called for redemption or tendered for repurchase pursuant to Section
3.5, such right shall not terminate, if the Company shall default in payment due
upon redemption or purchase thereof) to convert the principal amount of any such
Note, or any portion of such principal amount which is $1,000 or an integral
multiple thereof, into that number of fully paid and non-assessable shares of
Common Stock (as such shares shall then be constituted) obtained by dividing the
principal amount of the Note or portion thereof surrendered for conversion by
the Conversion Price in effect at such time, by surrender of the Note so to be
converted in whole or in part in the manner provided, together with any required
funds, in Section 14.2. A Note in respect of which a holder is exercising its
option to require repurchase upon a Fundamental Change pursuant to Section 3.5
may be converted only if such holder withdraws its election to exercise in
accordance with Section 3.5. A holder of Notes is not entitled to any rights of
a holder of Common Stock until such holder has converted his Notes to Common
Stock, and only to the extent such Notes are deemed to have been converted to
Common Stock under this Article XIV.

          SECTION 14.2 EXERCISE OF CONVERSION PRIVILEGE; ISSUANCE OF COMMON
STOCK ON CONVERSION; NO ADJUSTMENT FOR INTEREST OR DIVIDENDS. In order to
exercise the conversion privilege with respect to any Note in certificated form,
the holder of any such Note to be converted in whole or in part shall surrender
such Note, duly endorsed, at an office or agency maintained by the Company
pursuant to Section 4.2, accompanied by the funds, if any, required by this
Section 14.2, and shall give written notice of conversion in the form provided
on the Notes (or such other notice which is acceptable to the Company) to the
office or agency that the holder elects to convert such Note or the portion
thereof specified in said notice. Such notice shall also state the name or names
(with address or addresses) in which the certificate or certificates for shares
of Common Stock which shall be issuable on such conversion shall be issued, and
shall be accompanied by transfer taxes, if required pursuant to Section 14.7.
Each such Note surrendered for conversion shall, unless the shares issuable on
conversion are to be issued in the same name as the registration of such Note,
be duly endorsed by, or be accompanied by instruments of transfer in form
satisfactory to the Company duly executed by, the holder or his duly authorized
attorney.

          In order to exercise the conversion privilege with respect to any
interest in a Note in global form, the holder must complete the appropriate
instruction form for conversion pursuant to the Depository's book-entry
conversion program, deliver by book-entry delivery an interest in such Note in
global form, furnish appropriate endorsements and transfer documents if required
by the Company or the Trustee or conversion agent, and pay the funds, if any,
required by this Section 14.2 and any transfer taxes if required pursuant to
Section 14.7.

          As promptly as practicable after satisfaction of the requirements for
conversion set forth above, subject to compliance with any restrictions on
transfer if shares issuable on conversion are

                                       50
   58

to be issued in a name other than that of the Noteholder (as if such transfer
were a transfer of the Note or Notes (or portion thereof) so converted), the
Company shall issue and shall deliver to such holder at the office or agency
maintained by the Company for such purpose pursuant to Section 4.2, a
certificate or certificates for the number of full shares of Common Stock
issuable upon the conversion of such Note or portion thereof in accordance with
the provisions of this Article and, if applicable, a check or cash in respect of
any fractional interest in respect of a share of Common Stock arising upon such
conversion, as provided in Section 14.3.

          Each conversion shall be deemed to have been effected as to any such
Note (or portion thereof) on the date on which the requirements set forth above
in this Section 14.2 have been satisfied as to such Note (or portion thereof),
and the Person in whose name any certificate or certificates for shares of
Common Stock shall be issuable upon such conversion shall be deemed to have
become on said date the holder of record of the shares represented thereby;
provided, however, that any such surrender on any date when the stock transfer
books of the Company shall be closed shall constitute the Person in whose name
the certificates are to be issued as the record holder thereof for all purposes
on the next succeeding day on which such stock transfer books are open, but such
conversion shall be at the Conversion Price in effect on the date upon which
such Note shall be surrendered in accordance with the applicable terms of the
Indenture.

          Any Note or portion thereof surrendered for conversion during the
period from the close of business on the record date for any interest payment
date to the close of business on the Business Day next preceding the following
interest payment date must (unless such Note or portion thereof being converted
shall have been called for redemption on a redemption date, or tendered for
repurchase on a repurchase date, that occurs during the period from the close of
business on such record date to the close of business on the Business Day next
preceding the following interest payment date), be accompanied by payment, in
same day funds or other funds acceptable to the Company, of an amount equal to
the interest otherwise payable on such interest payment date on the principal
amount being converted; provided, however, that no such payment need be made if
there shall exist at the time of conversion a default in the payment of interest
on the Notes. Except as provided above in this Section 14.2, no payment or other
adjustment shall be made for interest accrued on any Note converted or for
dividends on any shares issued upon the conversion of such Note as provided in
this Article.

          Upon the conversion of an interest in a Note in global form, the
Trustee (or other conversion agent appointed by the Company), or the Custodian
at the direction of the Trustee (or other conversion agent appointed by the
Company), shall make a notation on such Note in global form as to the reduction
in the principal amount represented thereby. Upon the conversion of an interest
in a Note in definitive form, the Trustee (or other conversion agent appointed
by the Company), or the Custodian at the direction of the Trustee (or the
conversion agent appointed by the Company), shall authenticate and deliver to
the holder of the Note so surrendered, without charge to him, a new Note or
Notes in authorized denominations in an aggregate principal amount equal to the
unconverted portion of the surrendered Note. The Company shall notify the
Trustee in writing of any conversions of Notes effected through any conversion
agent other than the Trustee.

          SECTION 14.3 CASH PAYMENTS OR ROUNDING UP IN LIEU OF FRACTIONAL
SHARES. No fractional shares of Common Stock or scrip representing fractional
shares shall be issued upon conversion of Notes. If more than one Note shall be
surrendered for conversion at one time by the same holder, the number of full
shares that shall be issuable upon conversion shall be

                                       51
   59

computed on the basis of the aggregate principal amount of the Notes (or
specified portions thereof to the extent permitted thereby) so surrendered. If
any fractional share of stock would be issuable upon the conversion of any Note
or Notes, the Company shall, at its option, make an adjustment and payment
therefor in cash at the Closing Price thereof on the last Business Day
immediately preceding the day on which the Notes (or specified portions thereof)
are deemed to have been converted to the holder of Notes or round up the number
of shares to be received to the nearest whole share.

          SECTION 14.4 CONVERSION PRICE. The conversion price shall be as
specified in the form of Note (herein called the "Conversion Price") attached as
Exhibit A hereto, subject to adjustment as provided in this Article XIV.

          SECTION 14.5 ADJUSTMENT OF CONVERSION PRICE. The Conversion Price
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 Price 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 shall be reduced by multiplying such
Conversion Price by a fraction the numerator of which shall be the number of
shares of the Common Stock outstanding at the close of business on the date
fixed for such determination and the denominator of which shall be the sum of
such number of shares and the total number of shares constituting such dividend
or other distribution, such reduction, subject to the Company's rights under
Section 14.5(l), to become effective immediately after the opening of business
on the day following the date fixed for such determination. The Company will not
pay any dividend or make any distribution on shares of Common Stock held in the
treasury of the Company. If any dividend or distribution of the type described
in this Section 14.5(a) is declared but not so paid or made, the Conversion
Price shall again be adjusted to the Conversion Price 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 45 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
defined below) on the date fixed for determination of stockholders entitled to
receive such rights or warrants, the Conversion Price shall be adjusted so that
the same shall equal the price determined by multiplying the Conversion Price in
effect immediately prior to the date fixed for determination of stockholders
entitled to receive such rights or warrants by a fraction the numerator of which
shall be the number of shares of Common Stock outstanding at the close of
business on the date fixed for determination of stockholders entitled to receive
such rights and warrants plus the number of shares that the aggregate offering
price of the total number of shares so offered would purchase at such Current
Market Price, and the denominator of which shall be the number of shares of
Common Stock outstanding on the date fixed for determination of stockholders
entitled to receive such rights and warrants plus the total number of additional
shares of Common Stock offered for subscription or purchase. Such adjustment
shall be successively made whenever any such rights and warrants are issued, and
shall, subject to the Company's rights under Section 14.5(l), become effective
immediately after the opening

                                       52
   60

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 Price shall be readjusted to the Conversion Price 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. In the event that such rights or
warrants are not so issued, the Conversion Price shall again be adjusted to be
the Conversion Price 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 Common Stock at less than such
Current Market Price, and in determining the aggregate offering price of such
shares of Common Stock, there shall be taken into account any consideration
received by the Company for such rights or warrants, the value of such
consideration, if other than cash, to be determined by the Board of Directors,
whose determination shall be conclusive and described in a resolution of 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 Price
in effect at the opening of business on the day following the day upon which
such subdivision becomes effective shall be proportionately reduced, and
conversely, in case outstanding shares of Common Stock shall be combined into a
smaller number of shares of Common Stock, the Conversion Price in effect at the
opening of business on the day following the day upon which such combination
becomes effective shall be proportionately increased, such reduction or
increase, 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 shares of any class of capital
stock of the Company (other than any dividends or distributions to which Section
14.5(a) applies) or evidences of its indebtedness or assets (including
securities, but excluding any rights or warrants referred to in Section 14.5(b),
and excluding any dividend or distribution (x) paid exclusively in cash or (y)
referred to in Section 14.5(a) (any of the foregoing hereinafter in this Section
14.5(d) called the "Securities")), then, in each such case (unless the Company
elects to reserve such Securities for distribution to the Noteholders upon the
conversion of the Notes so that any such holder converting Notes will receive
upon such conversion, in addition to the shares of Common Stock to which such
holder is entitled, the amount and kind of such Securities which such holder
would have received if such holder had converted its Notes into Common Stock
immediately prior to the Record Date (as defined in Section 14.5(h) for such
distribution of the Securities), the Conversion Price shall be reduced so that
the same shall be equal to the price determined by multiplying the Conversion
Price in effect on the Record Date with respect to such distribution by a
fraction the numerator of which shall be the Current Market Price per share of
the Common Stock 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 Securities so distributed applicable to one share of Common Stock
and the denominator of which shall be the Current Market Price per share of the
Common Stock on such Record Date, such reduction, subject to the Company's
rights under Section 14.5(l), to become effective immediately prior to the
opening of business on the day following such Record Date; provided, however,
that in the event the then fair market value (as so determined) of the portion
of the Securities so distributed applicable to one share of Common Stock is
equal to or greater

                                       53
   61

than the Current Market Price of the Common Stock on such Record Date, in lieu
of the foregoing adjustment, adequate provision shall be made so that each
Noteholder shall have the right to receive upon conversion the amount of
Securities such holder would have received had such holder converted each Note
on such Record Date. In the event that such dividend or distribution is not so
paid or made, the Conversion Price shall again be adjusted to be the Conversion
Price 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 14.5(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 of the Common Stock.

          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 14.5 (and no adjustment to the
Conversion Price under this Section 14.5 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 Price shall be made under this Section 14.5(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 Price under this Section 14.5
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 Price shall be readjusted upon such final redemption or repurchase to
give effect to such distribution or Trigger Event, as the case may be, as though
it were a cash distribution, equal to the per share redemption or repurchase
price received by a holder 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 redemption or
repurchase, and (2) in the case of such rights or warrants that shall have
expired or been terminated without exercise by any holders thereof, the
Conversion Price shall be readjusted as if such rights and warrants had not been
issued.

          For purposes of this Section 14.5(d) and Sections 14.5(a) and (b),
any dividend or distribution to which this Section 14.5(d) is applicable that
also includes shares of Common Stock, or rights or warrants to subscribe for or
purchase shares of Common Stock (or both), shall be deemed instead to be (1) a
dividend or distribution of the evidences of indebtedness, assets or shares of
capital stock other than such shares of Common Stock or rights or warrants (and
any Conversion Price reduction required by this Section 14.5(d) with respect to
such dividend or distribution shall then be made) immediately followed by (2) a
dividend or distribution of such

                                       54
   62

shares of Common Stock or such rights or warrants (and any further Conversion
Price reduction required by Sections 14.5(a) and (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" and "the date fixed for such determination" within the meaning of
Sections 14.5(a) and (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
14.5(a).

               (e) In case the Company shall, by dividend or otherwise,
distribute to all holders of its Common Stock cash (excluding (x) any quarterly
cash dividend on the Common Stock to the extent the aggregate cash dividend per
share of Common Stock in any fiscal quarter does not exceed the greater of (A)
the amount per share of Common Stock of the next preceding quarterly cash
dividend on the Common Stock to the extent that such preceding quarterly
dividend did not require any adjustment of the Conversion Price pursuant to this
Section 14.5(e) (as adjusted to reflect subdivisions, or combinations of the
Common Stock), and (B) 3.75% of the arithmetic average of the Closing Price
(determined as set forth in Section 14.5(h)) during the ten Trading Days (as
defined in Section 14.5(h)) immediately prior to the date of declaration of such
dividend, and (y) any dividend or distribution in connection with the
liquidation, dissolution or winding up of the Company, whether voluntary or
involuntary), then, in such case, the Conversion Price shall be reduced so that
the same shall equal the price determined by multiplying the Conversion Price in
effect immediately prior to the close of business on such Record Date by a
fraction the numerator of which shall be the Current Market Price of the Common
Stock on the Record Date less the amount of cash so distributed (and not
excluded as provided above) applicable to one share of Common Stock and the
denominator of which shall be such Current Market Price of the Common Stock,
such reduction, subject to the Company's rights under Section 14.5(l), to be
effective immediately prior to the opening of business on the day following the
Record Date; provided, however, that in the event the portion of the cash so
distributed applicable to one share of Common Stock is equal to or greater
than the Current Market Price of the Common Stock on the Record Date, in lieu of
the foregoing adjustment, adequate provision shall be made so that each
Noteholder shall have the right to receive upon conversion the amount of cash
such holder would have received had such holder converted each Note on the
Record Date. In the event that such dividend or distribution is not so paid or
made, the Conversion Price shall again be adjusted to be the Conversion Price
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
14.5(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
amount of the quarterly cash dividend permitted to be excluded pursuant hereto.
If an adjustment is required to be made as set forth in this Section 14.5(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 (other than any tender
offer or exchange offer that is made and consummated for any and all shares of
the Common Stock) shall expire and such tender or exchange offer (as in effect
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

                                       55
   63

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 Current Market Price of the
Common Stock on the Trading Day next succeeding the Expiration Time, the
Conversion Price shall be reduced so that the same shall equal the price
determined by multiplying the Conversion Price in effect immediately prior to
the Expiration Time by a fraction the numerator of which shall be the number of
shares of Common Stock outstanding (including any tendered or exchanged shares)
on the Expiration Time multiplied by the Current Market Price of the Common
Stock on the Trading Day next succeeding the Expiration Time and the denominator
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) on the Expiration Time and the
Current Market Price of the Common Stock on the Trading Day next succeeding the
Expiration Time, such reduction to become effective immediately prior to the
opening of business on the second Trading Day following the Expiration Time. In
the event that the Company is obligated to purchase shares pursuant to any such
tender or exchange offer, but the Company is permanently prevented by applicable
law from effecting any such purchases or all such purchases are rescinded, the
Conversion Price shall again be adjusted to be the Conversion Price that would
then be in effect if such tender or exchange offer had not been made.

               (g) In the case of a tender or exchange offer made by a Person
other than the Company or any Subsidiary (a) for an amount that increases the
offeror's ownership of Common Stock to more than 25% of the Common Stock
outstanding (provided that in the case of any offeror whose ownership percentage
of the Common Stock is 15% or more prior to the commencement of the tender offer
or exchange offer, this requirement would not be met unless the tender offer or
exchange offer would increase the offeror's ownership of Common Stock by more
than 10% of the total shares of Common Stock outstanding), (b) that involves the
payment by such Person of consideration per share of Common Stock having a fair
market value (as determined by the Board of Directors, whose determination shall
be conclusive, and described in a resolution of the Board of Directors) at the
last time (the "Offer Expiration Time") tenders or exchanges may be made
pursuant to such tender or exchange offer (as it shall have been amended) that
exceeds the Current Market Price of the Common Stock on the Trading Day next
succeeding the Offer Expiration Time, (c) in which, as of the Offer Expiration
Time, the Board of Directors is not recommending rejection of the offer and (d)
in which the average of the daily Closing Price per share of the Common Stock
for the ten consecutive Trading Days ending ten Trading Days prior to the public
announcement of the tender offer or exchange offer (the "Pre- Offer Reference
Price") exceeds 105% of the average of the daily Closing Price per share of the
Common Stock for the ten Trading Days commencing ten Trading Days following the
Offer Expiration Time (the "Post-Offer Reference Price") the Conversion Price
shall be reduced so that the same shall equal the price determined by
subtracting from the Conversion Price in effect immediately prior to the Offer
Expiration Time an amount determined by multiplying the Conversion Price in
effect immediately prior to the Offer Expiration Time by a fraction, the
numerator of which shall be (x) the difference between the Pre-Offer Reference
Price and the Post-Offer Reference Price multiplied by (y) the number of shares
of Common Stock outstanding immediately prior to the Offer Expiration Time (less
all shares validly tendered or exchanged and

                                       56
   64

not withdrawn as of the Offer Expiration Time) and the denominator of which
shall be the product of the Pre-Offer Reference Price and the number of shares
of Common Stock outstanding immediately prior to the Offer Expiration Time
(including any tendered or exchanged shares). Any reduction in the Conversion
Price provided for in this Section 14.5(g) shall become effective retroactive to
immediately prior to the opening of business on the day following the Offer
Expiration Time. In the event that such Person is obligated to purchase shares
pursuant to any such tender or exchange offer, but such Person is permanently
prevented by applicable law from effecting any such purchases or all such
purchases are rescinded, the Conversion Price shall again be adjusted to be the
Conversion Price which would then be in effect if such tender or exchange offer
had not been made. Notwithstanding the foregoing, the adjustment described in
this Section 14.5(g) shall not be made if, as of the Offer Expiration Time, the
offering documents with respect to such offer disclose a plan or intention to
cause the Company to engage in any transaction described in Article XI.

               (h) For purposes of this Section 14.5, the following terms shall
have the meaning indicated:

                    (1) "Closing Price" with respect to any securities on any
day means the closing sale price, regular way, on such day or, in case no such
sale takes place on such day, the average of the reported closing bid and asked
prices, regular way, in each case as quoted on the Nasdaq National Market or, if
such security is not quoted or listed or admitted to trading on such Nasdaq
National Market, on the principal national security exchange or quotation system
on which such security is quoted or listed or admitted to trading or, if not
quoted or listed or admitted to trading on any national securities exchange or
quotation system, the average of the closing bid and asked prices of such
security on the over-the-counter market on the day in question as reported by
the National Quotation Bureau Incorporated, or a similar generally accepted
reporting service, or if not so available, in such manner as furnished by any
New York Stock Exchange member firm selected from time to time by the Board of
Directors for that purpose, or a price determined in good faith by the Board of
Directors or, to the extent permitted by applicable law, a duly authorized
committee thereof, whose determination shall be conclusive.

                    (2) "Current Market Price" means the average of the daily
Closing Prices per share of Common Stock for the ten consecutive Trading Days
immediately prior to the date in question. The Current Market Price shall be
appropriately adjusted to take into account the occurrence during the period
commencing on the first of such Trading Days during such ten- Trading Day period
and ending on the date in question of any other events that would require an
adjustment of the Conversion Price pursuant to Section 14.5 of this Indenture.

                    (3) "fair market value" means the amount which a willing
buyer would pay a willing seller in an arm's-length transaction.

                    (4) "Record Date" means, 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).

                                       57
   65

                    (5) "Trading Day" means (x) if the applicable security is
quoted on the Nasdaq National Market, a day on which trades may be made thereon
or (y) if the applicable security is listed or admitted for trading on the New
York Stock Exchange or another national security exchange, a day on which the
New York Stock Exchange or another national security exchange is open for
business or (z) if the applicable security is not so listed, admitted for
trading or quoted, any day other than a Saturday or Sunday or a day on which
banking institutions in the State of New York are authorized or obligated by law
or executive order to close.

               (i) The Company may make such reductions in the Conversion Price,
in addition to those required by Sections 14.5(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 reduce the Conversion Price by any amount for any period of time if the
period is at least 20 days, the reduction is irrevocable during the period and
the Board of Directors shall have made a determination that such reduction would
be in the best interests of the Company, which determination shall be
conclusive. Whenever the Conversion Price is reduced pursuant to the preceding
sentence, the Company shall mail to holders of record of the Notes a notice of
the reduction at least 15 days prior to the date the reduced Conversion Price
takes effect, and such notice shall state the reduced Conversion Price and the
period during which it will be in effect.

               (j) No adjustment in the Conversion Price shall be required
unless such adjustment would require an increase or decrease of at least 1% in
such price; provided, however, that any adjustments that by reason of this
Section 14.5(j) are not required to be made shall be carried forward and taken
into account in any subsequent adjustment. All calculations under this Article
XIV shall be made by the Company and shall be made to the nearest tenth of one
cent or to the nearest one-hundredth (1/100) of a share, as the case may be. No
adjustment need be made for rights to purchase Common Stock pursuant to a
Company plan for reinvestment of dividends or interest. To the extent the Notes
become convertible into cash, assets, property or securities (other than capital
stock of the Company), no adjustment need be made thereafter as to the cash,
assets, property or such securities. Interest will not accrue on the cash.

               (k) Whenever the Conversion Price 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 Price
after such adjustment and setting forth a brief statement of the facts requiring
such adjustment. Promptly after delivery of such certificate, the Company shall
prepare a notice of such adjustment of the Conversion Price setting forth the
adjusted Conversion Price and the date on which each adjustment becomes
effective and shall mail such notice of such adjustment of the Conversion Price
to the holder of each Note at his last address appearing on the Note register
provided for in Section 2.5 of this Indenture, within 20 days after execution
thereof. Failure to deliver such notice shall not affect the legality or
validity of any such adjustment.

               (l) In any case in which this Section 14.5 provides that an
adjustment shall become effective immediately after a record date for an event
or any other date specified herein,

                                       58
   66

occurring prior to the event, that is the basis for such adjustment, the Company
may defer until the occurrence of such event (i) issuing to the holder of any
Note converted after such record or other specified date or other date and
before the occurrence of such event the additional shares of Common Stock
issuable upon such conversion by reason of the adjustment required by such event
over and above the Common Stock issuable upon such conversion before giving
effect to such adjustment and (ii) paying to such holder any amount in cash or
additional shares in lieu of any fraction pursuant to Section 14.3.

               (m) For purposes of this Section 14.5, the number of shares of
Common Stock at any time outstanding shall not include shares held in the
treasury of the Company but shall include shares issuable in respect of scrip
certificates issued in lieu of fractions of shares of Common Stock. The Company
will not pay any dividend or make any distribution on shares of Common Stock
held in the treasury of the Company.

          SECTION 14.6 EFFECT OF RECLASSIFICATION, CONSOLIDATION, MERGER OR
SALE. 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 14.5(c) applies), (ii) any consolidation, merger 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 conveyance 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 each supplemental indenture) providing that the Notes 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, combination, sale or conveyance by a holder of a number
of shares of Common Stock issuable upon conversion of such Notes (assuming, for
such purposes, a sufficient number of authorized shares of Common Stock
available to convert all such Notes) immediately prior to such reclassification,
change, consolidation, merger, combination, sale or conveyance assuming such
holder of Common Stock did not exercise his rights of election, if any, as to
the kind or amount of securities, cash or other property receivable upon such
reclassification, change, consolidation, merger, combination, sale or conveyance
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 conveyance 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 14.6 the kind and amount of securities, cash or other property
receivable upon such reclassification, change, consolidation, merger,
combination, sale or conveyance 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.

          The Company shall cause notice of the execution of such supplemental
indenture to be mailed to each holder of Notes, at its address appearing on the
Note register provided for in


                                       59
   67

Section 2.5 of this Indenture, within 20 days after execution thereof. Failure
to deliver such notice shall not affect the legality or validity of such
supplemental indenture.

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

          If this Section 14.6 applies to any event or occurrence, Section
14.5 shall not apply.

          SECTION 14.7 TAXES ON SHARES ISSUED. The issue of stock certificates
on conversions of Notes shall be made without charge to the converting
Noteholder for any tax in respect of the issue thereof. The Company shall not,
however, be required to pay any tax which may be payable in respect of any
transfer involved in the issue and delivery of stock in any name other than that
of the holder of any Note converted, and the Company shall not be required to
issue or deliver any such stock certificate unless and until the Person or
Persons requesting the issue thereof shall have paid to the Company the amount
of such tax or shall have established to the satisfaction of the Company that
such tax has been paid.

          SECTION 14.8 RESERVATION OF SHARES; SHARES TO BE FULLY PAID;
COMPLIANCE WITH GOVERNMENTAL REQUIREMENTS; LISTING OF COMMON STOCK. 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 Notes from time to time as such Notes are presented
for conversion.

          Before taking any action which would cause an adjustment reducing the
Conversion Price below the then par value, if any, of the shares of Common Stock
issuable upon conversion of the Notes, the Company will take all corporate
action 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 Price.

          The Company covenants that all shares of Common Stock which may be
issued upon conversion of Notes will upon issue be fully paid and non-assessable
by the Company and free from all taxes, liens and charges with respect to the
issue thereof.

          The Company covenants that, subject to the terms of this Indenture,
the Registration Rights Agreement and the compliance by the holders of the Notes
to be converted with applicable law, if any shares of Common Stock to be
provided for the purpose of conversion of Notes 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 endeavor to secure such registration
or approval, as the case may be.

          The Company further covenants that, subject to the terms of this
Indenture, the Registration Rights Agreement and compliance by the holders of
the Notes with applicable law, if at any time the Common Stock shall be listed
on the Nasdaq National Market 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 Notes; provided, however, that,
if the rules of such

                                       60
   68

exchange or automated quotation system permit the Company to defer the listing
of such Common Stock until the first conversion of the Notes into Common Stock
in accordance with the provisions of this Indenture, the Company covenants to
list such Common Stock issuable upon conversion of the Notes in accordance with
the requirements of such exchange or automated quotation system at such time.

          SECTION 14.9 RESPONSIBILITY OF TRUSTEE. The Trustee and any other
conversion agent shall not at any time be under any duty or responsibility to
any holder of Notes to determine the Conversion Price or whether any facts exist
which may require any adjustment of the Conversion Price, or with respect to the
nature or extent or calculation of any such adjustment when made, or with
respect to the method employed, or herein or in any supplemental indenture
provided to be employed, in making the same. The Trustee and any other
conversion agent shall not be accountable with respect to the validity or value
(or the kind or amount) of any shares of Common Stock, or of any securities or
property, which may at any time be issued or delivered upon the conversion of
any Note; and the Trustee and any other conversion agent make no representations
with respect thereto. Neither the Trustee nor any conversion agent shall be
responsible for any failure of the Company to issue, transfer or deliver any
shares of Common Stock or stock certificates or other securities or property or
cash upon the surrender of any Note for the purpose of conversion or to comply
with any of the duties, responsibilities or covenants of the Company contained
in this Article. Without limiting the generality of the foregoing, neither the
Trustee nor any conversion agent shall be under any responsibility to determine
the correctness of any provisions contained in any supplemental indenture
entered into pursuant to Section 14.6 relating either to the kind or amount of
shares of stock or securities or property (including cash) receivable by
Noteholders upon the conversion of their Notes after any event referred to in
such Section 14.6 or to any adjustment to be made with respect thereto, but,
subject to the provisions of Section 7.1, may accept as conclusive evidence of
the correctness of any such provisions, and shall be protected in relying upon,
the Officers' Certificate (which the Company shall be obligated to file with the
Trustee prior to the execution of any such supplemental indenture) with respect
thereto.

          SECTION 14.10 NOTICE TO HOLDERS PRIOR TO CERTAIN ACTIONS. In
case:

               (a) the Company shall declare a dividend (or any other
distribution) on its Common Stock that would require an adjustment in the
Conversion Price pursuant to Section 14.5; or

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

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

                                       61
   69

               (d) of the voluntary or involuntary dissolution, liquidation or
winding up of the Company or any Significant Subsidiary;

the Company shall cause to be filed with the Trustee and to be mailed to each
holder of Notes at his address appearing on the Note register provided for in
Section 2.5 of this Indenture, as promptly as possible but in any event at least
ten days prior to the applicable date hereinafter specified, a notice stating
(x) the date on which a record is to be taken for the purpose of such dividend,
distribution or rights or warrants, or, if a record is not to be taken, the date
as of which the holders of Common Stock of record to be entitled to such
dividend, distribution or rights are to be determined, or (y) the date on which
such reclassification, consolidation, merger, sale, transfer, dissolution,
liquidation or winding up is expected to become effective or occur, and the date
as of which it is expected that holders of Common Stock of record shall be
entitled to exchange their Common Stock for securities or other property
deliverable upon such reclassification, consolidation, merger, sale, transfer,
dissolution, liquidation or winding up. Failure to give such notice, or any
defect therein, shall not affect the legality or validity of such dividend,
distribution, reclassification, consolidation, merger, sale, transfer,
dissolution, liquidation or winding up.

                                   ARTICLE XV

                            MISCELLANEOUS PROVISIONS

          SECTION 15.1 PROVISIONS BINDING ON COMPANY'S SUCCESSORS. All the
covenants, stipulations, promises and agreements by the Company contained in
this Indenture shall bind its successors and assigns whether so expressed or
not.

          SECTION 15.2 OFFICIAL ACTS BY SUCCESSOR CORPORATION. Any act or
proceeding by any provision of this Indenture authorized or required to be done

done and performed with like force and effect by the like board, committee or
officer of any Person that shall at the time be the lawful sole successor of the

          SECTION 15.3 ADDRESSES FOR NOTICES, ETC. Any notice or demand which
by any provision of this Indenture is required or permitted to be given or
served by the Trustee or by the holders of Notes on the Company shall be deemed
to have been sufficiently given or made, for all purposes, if given or served by
being deposited postage prepaid by registered or certified mail in a post office
letter box addressed (until another address is filed by the Company with the
Trustee) to Nextel Communications, Inc., 2001 Edmund Halley Drive, Reston,
Virginia 20191, Attention: Secretary. Any notice, direction, request or demand
hereunder to or upon the Trustee shall be deemed to have been sufficiently given
or made, for all purposes, if given or served by being deposited, postage
prepaid, by registered or certified mail in a post office letter box addressed
to the Corporate Trust Office, which office is, at the date as of which this
Indenture is dated, located at 311 West Monroe Street, Chicago, Illinois 60606,

   70

          Any notice or communication mailed to a Noteholder shall be mailed to
him by first class mail, postage prepaid, at his address as it appears on the
Note register and shall be sufficiently given to him if so mailed within the
time prescribed. In respect of notices pursuant to Sections 3.1 and 3.5, in
addition to notices sent by mail as set forth in the first sentence of this
paragraph, the Company shall make a public announcement of the information
contained in such notice by release made to Reuters Economic Services and
Bloomberg Business News.

          Failure to mail a notice or communication to a Noteholder or any
defect in it shall not affect its sufficiency with respect to other Noteholders.
If a notice or communication is mailed in the manner provided above, it is duly
given, whether or not the addressee receives it.

          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 or after the event, and such waiver shall be the equivalent of such
notice. Waivers of notice by Noteholders shall be filed with the Trustee, but
such filing shall not be a condition precedent to the validity of any action
taken in reliance upon such waiver.

          In case by reason of the suspension of regular mail service or by
reason of any other cause it shall be impracticable to give such notice by mail,
then such notification as shall be made with the approval of the Trustee shall
constitute a sufficient notification for every purpose hereunder.

          SECTION 15.4 GOVERNING LAW. This Indenture and each Note shall be
deemed to be a contract made under the laws of the State of New York, and for
all purposes shall be construed in accordance with the laws of the State of New
York without giving effect to any conflicts or choice of law principles which
otherwise might be applicable. The Trustee, the Company and the Noteholders
agree to submit to the jurisdiction of the courts of the state of New York in
any action or proceeding arising out of or relating to this Indenture or the
Notes.

          SECTION 15.5 EVIDENCE OF COMPLIANCE WITH CONDITIONS PRECEDENT;

conditions precedent have been complied with.

          Each certificate or opinion provided for in this Indenture and
delivered to the Trustee with respect to compliance with a condition or covenant
provided for in this Indenture shall include: (1) a statement that the person
making such certificate or opinion has read such covenant or condition; (2) a
brief statement as to the nature and scope of the examination or investigation
upon which the statement or opinion contained in such certificate or opinion is
based; (3) a statement that, in the opinion of such person, he has made such
examination or investigation as is necessary to enable him to express an
informed opinion as to whether or not such covenant or condition has been
complied with; and (4) a statement as to whether or not, in the opinion of such

          SECTION 15.6 LEGAL HOLIDAYS. In any case in which the date of
maturity of interest on or principal of the Notes or the date fixed for
redemption of any Note will not be a Business Day, then payment of such interest
on or principal of the Notes need not be made on such date, but may be made on
the next succeeding Business Day with the same force and effect as if made on
the date of maturity or the date fixed for redemption, and no interest shall
accrue for the period from and after such date.

          SECTION 15.7 TRUST INDENTURE ACT. This Indenture is hereby made
subject to, and shall be governed by, the provisions of the Trust Indenture Act
required to be part of and to govern indentures qualified under the Trust
Indenture Act; provided, however, that, unless otherwise required by law,
notwithstanding the foregoing, this Indenture and the Notes issued hereunder
shall not be subject to the provisions of subsections (a)(1), (a)(2), and (a)(3)
of Section 314 of the Trust Indenture Act as now in effect or as hereafter
amended or modified; provided further that this Section 15.7 shall not require
this Indenture or the Trustee to be qualified under the Trust Indenture Act
prior to the time such qualification is in fact required under the terms of the
Trust Indenture Act, nor shall it constitute any admission or acknowledgment by
any party to the Indenture that any such qualification is required prior to the
time such qualification is in fact required under the terms of the Trust
Indenture Act. If any provision hereof limits, qualifies or conflicts with
another provision hereof which is required to be included in an indenture
qualified under the Trust Indenture Act, such required provision shall control.

          SECTION 15.8 NO SECURITY INTEREST CREATED. Nothing in this Indenture
or in the Notes, expressed or implied, shall be construed to constitute a
security interest under the Uniform Commercial Code or any other legislation, as
now or hereafter enacted and in effect, in any jurisdiction in which property of
the Company or its subsidiaries is located.

          SECTION 15.9 BENEFITS OF INDENTURE. Nothing in this Indenture or in
the Notes, express or implied, shall give to any Person, other than the parties
hereto, any paying agent, any authenticating agent, any Note registrar and their
successors hereunder and the holders of Notes, any benefit or any legal or
equitable right, remedy or claim under this Indenture.

          SECTION 15.10 TABLE OF CONTENTS, HEADINGS, ETC. The table of contents
and the titles and headings of the articles and sections of this Indenture have
been inserted for convenience of reference only, are not to be considered a part
hereof, and shall in no way modify or restrict any of the terms or provisions
hereof.

          SECTION 15.11 AUTHENTICATING AGENT. The Trustee may appoint an
authenticating agent that shall be authorized to act on its behalf, and subject
to its direction, in the authentication and delivery of Notes in connection with
the original issuance thereof and transfers and exchanges of Notes hereunder,
including under Sections 2.4, 2.5, 2.6, 2.7, 3.3 and 3.5, as fully to all
intents and purposes as though the authenticating agent had been expressly
authorized by this Indenture and those Sections to authenticate and deliver
Notes. For all purposes of this Indenture, the authentication and delivery of
Notes by the authenticating agent shall be deemed to be authentication and
delivery of such Notes "by the Trustee" and a certificate of authentication
executed on behalf of the Trustee by an authenticating agent shall be deemed to
satisfy any requirement hereunder or in the Notes for the Trustee's certificate
of authentication. Such

                                       64
   72

authenticating agent shall at all times be a Person eligible to serve as trustee
hereunder pursuant to Section 7.11.

          Any corporation into which any authenticating agent may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, consolidation or conversion to which any authenticating agent
shall be a party, or any corporation succeeding to the corporate trust business
of any authenticating agent, shall be the successor of the authenticating agent
hereunder, if such successor corporation is otherwise eligible under this
Section 15.11, without the execution or filing of any paper or any further act
on the part of the parties hereto or the authenticating agent or such successor
corporation.

          Any authenticating agent may at any time resign by giving written
notice of resignation to the Trustee and to the Company. The Trustee may at any
time terminate the agency of any authenticating agent by giving written notice
of termination to such authenticating agent and to the Company. Upon receiving
such a notice of resignation or upon such a termination, or in case at any time
any authenticating agent shall cease to be eligible under this Section, the
Trustee shall either promptly appoint a successor authenticating agent or itself
assume the duties and obligations of the former authenticating agent under this
Indenture and, upon such appointment of a successor authenticating agent, if
made, shall give written notice of such appointment of a successor
authenticating agent to the Company and shall mail notice of such appointment of
a successor authenticating agent to all holders of Notes as the names and
addresses of such holders appear on the Note register.

          The Company agrees to pay to the authenticating agent from time to
time such reasonable compensation for its services as shall be agreed upon in
writing between the Company and the authenticating agent.

          The provisions of Sections 7.2, 7.3, 7.4, 8.3 and this Section 15.11
shall be applicable to any authenticating agent.

          SECTION 15.12 EXECUTION IN COUNTERPARTS. This Indenture may be
executed in any number of counterparts, each of which shall be an original, but
such counterparts shall together constitute but one and the same instrument.

          Harris Trust and Savings Bank hereby accepts the trusts in this
Indenture declared and provided, upon the terms and conditions herein above set
forth.

                                       65

designated as its 5 1/4% Convertible Senior Notes due 2010 (herein called the
"Notes"), limited to the aggregate principal amount of $1,000,000,000 (or
$1,200,000,000 if the option set forth in Section 3 of the Purchase Agreement,
dated January 21, 2000 between the Company and Morgan Stanley & Co.
Incorporated, is exercised in full), all issued or to be issued under and
pursuant to an indenture dated as of January 26, 2000 (herein called the
"Indenture"), between the Company and Harris Trust and Savings Bank, as trustee
(herein called the "Trustee"), to which Indenture and all indentures
supplemental thereto reference is hereby made for a description of the rights,
limitations of rights, obligations, duties and immunities thereunder of the
Trustee, the Company and the holders of the Notes.

          In case an Event of Default, as defined in the Indenture, shall have
occurred and be continuing, the principal of, premium, if any, and accrued
interest (including Liquidated Damages Amount (as defined in the Indenture), if
any) on all Notes may be declared, and upon said declaration shall become, due
and payable, in the manner, with the effect and subject to the conditions
provided in the Indenture.

          The Indenture contains provisions permitting the Company and the
Trustee, with the consent of the holders of not less than a majority in
aggregate principal amount of the Notes at the time outstanding, evidenced as in
the Indenture provided, to execute supplemental indentures adding any provisions
to or changing in any manner or eliminating any of the provisions of the
Indenture or of any supplemental indenture or modifying in any manner the rights
of the holders of the Notes; provided, however, that no such supplemental
indenture shall (i) extend the fixed maturity of any Note, or reduce the rate or
extend the time for payment of interest thereon, or reduce the principal amount
thereof or premium, if any, thereon, or reduce any amount payable on redemption
thereof, or impair the right of any Noteholder to institute suit for the payment
thereof, or make the principal thereof or interest or premium, if any, thereon
payable in any coin or currency other than that provided in the Note, or after
the occurrence of a Fundamental Change, and subject to the terms of Section 3.5
of the Indenture, change the obligation of the Company to repurchase any Note
because of that Fundamental Change (as defined in the Indenture) in a manner
adverse to the holder of the Notes, or impair the right to convert the Notes
into Common Stock subject to the terms set forth in the Indenture, including
Section 14.6 thereof, without the consent of the holder of each Note so affected
or (ii) reduce the aforesaid percentage of Notes, the holders of which are
required to consent to any such supplemental indenture, without the consent of
the holders of all Notes then outstanding. Subject to the provisions of the
Indenture, the holders of a majority in aggregate principal amount of the Notes
at the time outstanding may on behalf of the holders of all of the Notes waive
any past default or Event of Default under the Indenture and its consequences
except a default in the payment of interest (including Liquidated Damages
Amount, if any) or any premium on or the principal of any of the Notes, a
default in the payment of redemption or repurchase price pursuant to Article III
or a failure by the Company to convert any Notes into Common Stock of the
Company or a




                                       A-7


   81

default in respect of a covenant or provisions hereof which under Article X
cannot be modified without the consent of the holders of each or all Notes then
outstanding or affected thereby. Any such consent or waiver by the holder of
this Note (unless revoked as provided in the Indenture) shall be conclusive and
binding upon such holder and upon all future holders and owners of this Note and
any Notes which may be issued in exchange or substitute hereof, irrespective of
whether or not any notation thereof is made upon this Note or such other Notes.

          No reference herein to the Indenture and no provision of this Note or
of the Indenture shall alter or impair the obligation of the Company, which is
absolute and unconditional, to pay the principal of and any premium and interest
(including Liquidated Damages Amount, if any) on this Note at the place, at the
respective times, at the rate and in the coin or currency herein prescribed.

          Interest on the Notes shall be computed on the basis of a 360-day year
of twelve 30-day months.

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

          At any time on or after January 18, 2003, and prior to maturity, the
Notes may be redeemed at the option of the Company, in whole or in part, upon
notice as set forth in the Indenture, at the following optional redemption
prices (expressed as percentages of the principal amount), together in each case
with accrued and unpaid interest, if any (including Liquidated Damages Amount,
if any) to, but excluding, the date fixed for redemption.

          If redeemed during the period beginning January 18, 2003 and ending on
January 14, 2004, at a redemption price of 103.500% and if redeemed during the
12-month period beginning January 15:

                            2005...................................102.333%
                            2006...................................101.750%
                            2007...................................101.167%
                            2008...................................100.583%



and 100% if on or after January 15, 2009; provided that if the date fixed for
redemption is after an interest payment record date and on or before January 15
or July 15, then the interest payable on the redemption date will be paid to the
person who, on the preceding January 1 or July 1, respectively, is the holder of
record.

          The Company shall not give notice of any redemption if a default in
the payment of interest on the Notes has occurred and is continuing.

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

          If a Fundamental Change occurs at any time prior to maturity or
redemption of the Notes, the Notes will be redeemable on the 30th day after
notice thereof at the option of the holder at a repurchase price equal to 100%
of the principal amount thereof, together with accrued interest to (but
excluding) the date of repurchase; provided that, if such Repurchase Date is
January 15 or July 15, the interest payable on the Repurchase Date will be paid
to the person who, on the preceding January 1 or July 1, respectively, is the
holder of record; provided, further, that the Company may omit to comply with
its obligation to repurchase any Notes upon the occurrence of a Fundamental
Change if, prior to the occurrence of such Fundamental Change, the holders of at
least a majority in aggregate principal amount of the Notes at the time
outstanding shall have waived such compliance, but no such waiver shall extend
to or affect the Company's obligations as set forth in Section 3.5 of the
Indenture except to the extent so expressly waived, and, until such waiver shall
become effective, the obligations of the Company and the duties of the Trustee
in respect of Section 3.5 of the Indenture shall remain in full force and
effect. The Notes will be repurchased in multiples of $1,000 principal amount.
The Company shall mail to all holders of record of the Notes a notice of the
occurrence of a Fundamental Change and of the repurchase right arising as a
result thereof on or before the tenth day after the occurrence of such
Fundamental Change. For a Note to be so repaid at the option of the holder, the
Company must receive at the office or agency of the Company maintained for that
purpose in accordance with the terms of the Indenture, such Note with the form
entitled "Option to Elect Repayment Upon a Fundamental Change" on the reverse
thereof duly completed, together with such Notes duly endorsed for transfer, on
or before the 30th day after the date of such notice (or if such 30th day is not
a Business Day, the immediately preceding Business Day).

          Subject to the provisions of the Indenture, the holder hereof has the
right, at its option, at any time after the original issuance of any Notes
through the close of business on the Business Day prior to the date of
repurchase, redemption or final maturity date of the Notes (unless the Company
shall default in payment due upon redemption or repurchase thereof) to convert
the principal hereof or any portion of such principal which is $1,000 or an
integral multiple thereof into that number of shares of the Company's Common
Stock, as said shares shall be constituted at the date of conversion, obtained
by dividing the principal amount of this Note or portion thereof to be converted
by the Conversion Price of $148.80 or such Conversion Price as adjusted from
time to time as provided in the Indenture, upon surrender of this Note, together
with a conversion notice as provided in the Indenture, to the Company at the
office or agency of the Company maintained for that purpose in accordance with
the terms of the Indenture, or at the option of such holder, the Corporate Trust
Office, and, unless the shares issuable on conversion are to be issued in the
same name as this Note, duly endorsed by, or accompanied by instruments of
transfer in form satisfactory to the Company duly executed by, the holder or by
his duly authorized attorney. No adjustment in respect of interest or dividends
will be made upon any conversion; provided, however, that if this Note shall be
surrendered for conversion during the period from the close of business on any
record date for the payment of interest to the close of business on the Business
Day preceding the interest payment date, this Note (unless it or the portion
being converted shall have been called for redemption or repurchase during the
period from the close of business on any record date for the payment of interest
to the close of business on the Business Day preceding the interest payment
date) must be accompanied by an amount, in same day funds or other funds
acceptable to the Company, equal to the interest payable on such



                                      A-9
   83

interest payment date on the principal amount being converted. No fractional
shares will be issued upon any conversion, but either an adjustment in cash will
be made, as provided in the Indenture, in respect of any fraction of a share
which would otherwise be issuable upon the surrender of any Note or Notes for
conversion or the number of shares shall be rounded up to full shares. A Note in
respect of which a holder is exercising its right to require repurchase upon a
Fundamental Change may be converted only if such holder withdraws its election
to exercise such right in accordance with the terms of the Indenture.

          Upon due presentment for registration of transfer of this Note at the
office or agency of the Company maintained for that purpose in accordance with
the terms of the Indenture, or at the option of the holder of this Note, at the
Corporate Trust Office, a new Note or Notes of authorized denominations for an
equal aggregate principal amount will be issued to the transferee in exchange
thereof; subject to the limitations provided in the Indenture, without charge
except for any tax or other governmental charge imposed in connection therewith.

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

          No recourse for the payment of the principal of or any premium or
interest on this Note, or for any claim based hereon or otherwise in respect
hereof; and no recourse under or upon any obligation, covenant or agreement of
the Company in the Indenture or any indenture supplemental thereto or in any
Note, or because of the creation of any indebtedness represented thereby, shall
be had against any incorporator, stockholder, employee, agent, officer or
director or subsidiary, as such, past, present or future, of the Company or of
any successor Person, either directly or through the Company or any successor
Person, whether by virtue of any constitution, statute or rule of law or by the
enforcement of any assessment or penalty or otherwise, all such liability being,
by acceptance hereof and as part of the consideration for the issue hereof,
expressly waived and released.

           This Note shall be deemed to be a contract made under the laws of New
York, and for all purposes shall be construed in accordance with the laws of New
York, without regard to principles of conflicts of laws.

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

                       FORM OF ACCREDITED INVESTOR LETTER

Harris Trust and Savings Bank
311 West Monroe Street
Chicago, Illinois 60606
Attention:  Indenture Trust

Ladies and Gentlemen:

          In connection with our proposed purchase of 5 1/4% Convertible Senior
Notes due 2010 (the "Notes") of Nextel Communications, Inc., a Delaware
corporation ("Nextel"), we confirm that:

          1. We understand that any subsequent transfer of Notes is subject to
certain restrictions and conditions set forth in the Indenture dated as of
January 26, 2000 (the "Indenture") relating to the Notes and the undersigned
agrees to be bound by, and not to resell, pledge or otherwise transfer the Notes
except in compliance with the Securities Act of 1933, as amended (the
"Securities Act"), and all applicable state securities laws.

          2. We understand that the offer and sale of the Notes have not been
registered under the Securities Act or pursuant to any state securities laws,
and that the Notes may therefore not be offered or sold within the United States
or to, for the account or benefit of, U.S. persons except as permitted in the
following sentence. We agree, on our own behalf and on behalf of any accounts
for which we are acting as hereinafter stated, that if we should sell any Notes,
we will do so only (i) to Nextel or any subsidiary thereof, (ii) inside the
United States in accordance with Rule 144A promulgated under the Securities Act
to a "qualified institutional buyer" (as defined therein), (iii) to an
"institutional accredited investor" (as defined below), provided that prior to
such transfer, such "institutional accredited investor" furnishes (or has
furnished on its behalf by a United States broker-dealer) to Nextel and the
Trustee (as defined in the Indenture) a signed letter containing certain
representations and agreements relating to the restrictions on transfer of the
Notes (the form of which letter can be obtained from the Trustee), (iv) pursuant
to the exemption from registration provided by Rule 144 promulgated under the
Securities Act (if applicable), or (v) pursuant to an effective registration
statement under the Securities Act, and we further agree to provide to any
person purchasing any of the Notes from us a notice advising such purchaser that
any resale of the Securities are restricted as stated herein.

          3. We understand that, on any proposed resale of any Notes, we will be
required to furnish to the Trustee and Nextel such certifications, written legal
opinions and other information as the Trustee and Nextel may reasonably require
to confirm that the proposed sale complies with the foregoing restrictions. We
further understand that the Notes purchased by us will bear a legend to the
foregoing effect.

           4. We are an institutional "accredited investor" (as defined in Rule
501(a)(1), (2), (3) or (7) of Regulation D promulgated under the Securities Act)
and have such knowledge and



                                       B-1

experience in financial and business matters as to be capable of evaluating the
merits and risks of our investment in the Notes, and we and any accounts for
which we are acting are each able to bear the economic risk of our or their
investment, as the case may be.

          5. We are acquiring the Notes purchased by us (i) other than in the
offering distribution from the initial purchaser thereof, and (ii) for our
account or for one or more accounts (each of which is an institutional
"accredited investor") as to each of which we exercise sole investment
discretion.

          You, Nextel and the Trustee, and their respective counsel are entitled
to rely upon this letter and are irrevocably authorized to produce this letter
or a copy hereof to any interested party in any administrative or legal
proceeding or official inquiry with respect to the matters covered hereby.

          THIS LETTER SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH,
THE INTERNAL LAWS OF THE STATE OF NEW YORK.

                                         Very truly yours,
