12.      MISCELLANEOUS

         12.1     This Agreement and the Schedule hereto constitute the entire
                  agreement and understanding between the parties as to its
                  subject matter and the Executive acknowledges that he has not
                  entered into this Agreement in reliance upon any
                  representation, warranty or undertaking which is not set out
                  in this Agreement or referred to in this Agreement as forming
                  part of the contract of employment of the Executive.

         12.2     The various provisions of this Agreement are severable and if
                  any provision is held to be invalid or unenforceable by any
                  court of competent jurisdiction then such invalidity or
                  unenforceability shall not affect the remaining provisions of
                  this Agreement.

         12.3     Notices by either party shall be given in writing and may be
                  delivered personally or sent by letter addressed to the other
                  party at its registered office for the time being or the last
                  known address. Any such notice given by letter shall be deemed
                  to have been given at the time at which the letter would be
                  delivered in the ordinary course of post if sent by post and
                  on the date of delivery if delivered personally.

         12.4     Any reference in this Agreement to an Act of Parliament shall
                  be deemed to include any statutory modification or
                  re-enactment thereof whenever made. The headings shall be
                  disregarded in construing this Agreement.

                                  THE SCHEDULE

                       Particulars of Terms of Employment

In accordance with the Employment Protection (Consolidation) Act 1978 the
following terms of the Employment apply from the Effective Date as provided in
the Agreement:-

(a)      JOB TITLE

         See clause 2.1

(b)      SALARY

         See clause 4.

(c)      HOURS OF WORK

         The Executive shall work such hours as may be necessary or appropriate
         from time to time to carry out his duties properly and effectively.

(d)      HOLIDAYS

         See clause 8.

(e)      COMPANY CAR

         The Company will provide the Executive with a company car, the type and
         model to be agreed by the Managing Director of Pearson, within limits
         established by the Remuneration Committee.

(f)      SICKNESS OR INJURY

         If the Executive is absent from work because of illness or injury his
         salary will continue to be paid for at least 180 days in any one
         calendar year subject to submission of a doctor's or self-certification
         certificate for each period of absence. The Company reserves the right
         to seek a separate medical report from the Company's doctor at any
         time. If absence exceeds 180 days (or if shorter periods of absence in
         total exceed 180 days) within any period of a calendar year, the
         Company will consider whether or not circumstances justify the
         continued payment of salary in whole or in part. If the Executive is
         totally incapacitated, his salary will continue to be paid by the
         Company for the first six months of his absence. All the foregoing is
         subject to clause 9.4.

(g)      MEDICAL INSURANCE

         The Company will provide free family coverage for the Executive under
         the Pearson Group Health Care Scheme. Coverage will be continued into
         retirement.

(h)      PENSION AND LIFE ASSURANCE

         The Executive will be eligible to join the Pearson Group Pension Plan,
         details of which

                                      -8-
<PAGE>

         will be advised separately, together with any special arrangements
         which may apply.

(i)      NOTICE

         See clauses 2.2 and 9.1.

(j)      DISCIPLINARY PROCEDURES

         The Executive will be subject to the disciplinary procedures of the
         Company in force from time to time, save in so far as they are modified
         by clause 9.2.

         The attention of the Executive is drawn to the fact that as a director
         of Pearson he is subject to such terms and conditions contained in the
         articles of association of Pearson as are applicable to directors and
         to the duties and obligations placed on him by the UK Companies Acts
         and other legislation and also, where appropriate, Stock Exchange
         regulations, including rules governing share dealings by directors and
         other employees adopted by the Board (the "Rules"), a copy of which has
         been handed to the Executive. The Executive may neither buy nor sell
         shares or loan stock of Pearson without first receiving clearance from
         another director in accordance with the Rules. The Executive may also
         neither buy nor sell securities of any other company the market price
         of which, as a result of unpublished information obtained by him by
         virtue of his employment with Pearson or the Company, he believes may
         be affected by action of Pearson or any of its subsidiaries. These
         restrictions are equally applicable to dealings by the Executive's
         spouse, children under the age of eighteen and other connected persons.
         The attention of the Executive is drawn to the further restrictions on
         "insider dealing" contained in the Criminal Justice Act 1993 in
         relation to the shares and loan stock of Pearson which apply throughout
         his employment and six months thereafter.

(k)      GRIEVANCE PROCEDURE

         If the Executive has a grievance in connection with his employment he
         should raise the matter in the first instance with the Managing
         Director of Pearson.

provisions of this paragraph shall not apply with respect to, the giving or
making of any notice, declaration, request or direction referred to in the next
paragraph. If any record date is set pursuant to this paragraph, the Holders of
Outstanding Securities on such record date, and no other Holders, shall be
entitled to take the relevant action, whether or not such Holders remain Holders
after such record date; PROVIDED that no such action shall be effective
hereunder unless taken on or prior to the applicable Record Expiration Date by
Holders of the requisite principal amount of Outstanding Securities on such
record date; and PROVIDED, FURTHER, that for the purpose of determining whether
Holders of the requisite principal amount of such Securities have taken such
action, no Security shall be deemed to have been Outstanding on such record date

Nothing in this paragraph shall prevent the Company from setting a new record
date for any action for which a record date has previously been set pursuant to
this paragraph (whereupon the record date previously set shall automatically and

the Holders of Outstanding Securities entitled to join in the giving or making
of (i) any Notice of Default, (ii) any declaration of acceleration referred to
in Section 5.02, (iii) any request to institute proceedings referred to in
Section 5.07(2), (iv) any direction referred to in Section 5.12 or (v) the
Required Consent. If any record date is set pursuant to this paragraph, the
Holders of Outstanding Securities on such record date, and no other Holders,
shall be entitled to join in such notice, declaration, request or direction,
whether or not such Holders remain Holders after such record date; PROVIDED that
no such action shall be effective hereunder unless taken on or prior to the
applicable Record Expiration Date by Holders of the requisite principal amount
of Outstanding Securities on such record date; and PROVIDED, FURTHER, that for
the purpose of determining whether Holders of the requisite principal amount of
such Securities have taken such action, no Security shall be deemed to have been
Outstanding on such record date unless it is also Outstanding on the date such
action is to become effective. Nothing in this paragraph shall be construed to
prevent the Trustee from setting a new record date for any action (whereupon the
record date previously set shall automatically and without any action by any
Person be canceled and of no effect), nor shall anything in this paragraph be
construed to render ineffective any action taken by Holders of the requisite
principal amount of Outstanding Securities on the date such action is taken.
Promptly after any record date is set pursuant to this paragraph, the Trustee,
at the Company's expense, shall cause notice of such record date, the matter(s)
to be submitted for potential action by Holders and the applicable Record
Expiration Date to be given to the Company in writing and to each Holder of
Securities in the manner set forth in Section 1.06.

    With respect to any record date set pursuant to this Section, the party
hereto that sets such record date may designate any day as the "Record
Expiration Date" and from time to time may change the Record Expiration Date to
any earlier or later day, provided that no such change shall be effective unless
notice of the proposed new Record Expiration Date is given to the other party
hereto in writing, and to each Holder of Securities in the manner set forth in
Section 1.06, on or before the existing Record

                                       21
<PAGE>
Expiration Date. If a Record Expiration Date is not designated with respect to
any record date set pursuant to this Section, the party hereto that set such
record date shall be deemed to have initially designated the 180th day after
such record date as the Record Expiration Date with respect thereto, subject to
its right to change the Record Expiration Date as provided in this paragraph.
Notwithstanding the foregoing, no Record Expiration Date shall be later than the
180th day after the applicable record date.

    Without limiting the foregoing, a Holder entitled hereunder to take any
action hereunder with regard to any particular Security may do so with regard to
all or any part of the principal amount of such Security or by one or more duly
appointed agents each of which may do so pursuant to such appointment with
regard to all or any part of such principal amount.

Section 1.05.  NOTICES, ETC., TO TRUSTEE AND COMPANY.

    Any request, demand, authorization, direction, notice, consent, waiver or
Act of Holders or other document provided or permitted by this Indenture to be
made upon, given or furnished to, or filed with,

        (1) the Trustee by any Holder or by the Company shall be sufficient for
    every purpose hereunder if made, given, furnished or filed in writing and
    mailed, first-class postage prepaid, to or with the Trustee at its Corporate
    Trust Office, Attention: Corporate Trust Administration, or

        (2) the Company by the Trustee or by any Holder shall be sufficient for
    every purpose hereunder (unless otherwise herein expressly provided) if in
    writing and mailed, first-class postage prepaid, to the Company addressed to
    it at the address of its principal office specified in the first paragraph
    of this instrument or at any other address previously furnished in writing
    to the Trustee by the Company.

Section 1.06.  NOTICE TO HOLDERS; WAIVER.

    Where this Indenture provides for notice to Holders of any event, such
notice shall be sufficiently given (unless otherwise herein expressly provided)
if in writing and mailed, first-class postage prepaid, to each Holder affected
by such event, at his address as it appears in the Security Register, not later
than the latest date (if any), and not earlier than the earliest date (if any),
prescribed for the giving of such notice. In any case where notice to Holders is
given by mail, neither the failure to mail such notice, nor any defect in any
notice so mailed, to any particular Holder shall affect the sufficiency of such
notice with respect to other Holders. Where this Indenture provides for notice
in any manner, such notice may be waived in writing by the Person entitled to
receive such notice, either before or after the event, and such waiver shall be
the equivalent of such notice. Waivers of notice by Holders 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 1.07.  CONFLICT WITH TRUST INDENTURE ACT.

    If any provision hereof limits, qualifies or conflicts with a provision of
the Trust Indenture Act that is required under such Act to be part of and govern
this Indenture, the latter provision shall control. If any provision of this
Indenture modifies or excludes any provision of the Trust Indenture Act that may
be so modified or excluded, the latter provision shall be deemed to apply to
this Indenture as so modified or to be excluded, as the case may be.

Section 1.08.  EFFECT OF HEADINGS AND TABLE OF CONTENTS.

    The Article and Section headings herein and the Table of Contents are for
convenience only and shall not affect the construction hereof.

successors and assigns, whether so expressed or not.

Section 1.10.  SEPARABILITY CLAUSE.

    In case any provision in this Indenture or in the Securities shall be
invalid, illegal or unenforceable, the validity, legality and enforceability of
the remaining provisions shall not in any way be affected or impaired thereby.

Section 1.11.  BENEFITS OF INDENTURE.

    Nothing in this Indenture or in the Securities, express or implied, shall
give to any Person, other than the parties hereto and their successors hereunder
and the Holders of Securities, any benefit or any legal or equitable right,
remedy or claim under this Indenture.

Section 1.12.  GOVERNING LAW.

    This Indenture and the Securities shall be governed by and construed in
accordance with the laws of the State of New York, without regard to principles
of conflicts of laws.

Section 1.13.  LEGAL HOLIDAYS.

    In any case where any Interest Payment Date, Redemption Date, Purchase Date
or Stated Maturity of any Security shall not be a Business Day, then
(notwithstanding any other provision of this Indenture or of the Securities)
payment of interest or principal (and premium, if any) need not be made on such
date, but may be made on the next succeeding Business Day with the same force
and effect (including with respect to the accrual of interest) as if made on the
Interest Payment Date, Redemption Date or Purchase Date, or at the Stated
Maturity.

Section 1.14.  NO RECOURSE AGAINST OTHERS.

    No recourse for the payment of the principal of, premium, if any, or
interest on any of the Securities, 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 contained in this Indenture, or in any of the
Securities, or because of the creation of any indebtedness represented thereby,
shall be had against any incorporator or against any past, present or future
partner, shareholder, other equity holder, officer, director, employee or
controlling person, as such, 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; 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
Securities.

    Nextel Partners, Inc., a corporation duly organized and existing under the
laws of the State of Delaware (herein called the "Company", which term includes
any successor Person under the Indenture hereinafter referred to), for value
received, hereby promises to pay to ____________, or registered assigns, the
principal amount of ______ Dollars on March 15, 2010 and to pay cash interest
thereon from July 27, 2000 or from the most recent Interest Payment Date to
which interest has been paid or duly provided for, semiannually in arrears on
March 15 and September 15 in each year, commencing September 15, 2000 at the
rate of 11% per annum, until the principal hereof is paid or duly provided for,
PROVIDED that any principal and premium, and any such installment of interest,
which is overdue shall bear interest at the rate of 11% per annum (to the extent
that the payment of such interest shall be legally enforceable), from the dates
such amounts are due until they are paid or duly provided for, and such interest
shall be payable on demand. The interest so payable, and punctually paid or duly
provided for, on any Interest Payment Date will, as provided in such Indenture,
be paid to the Person in whose name this Security (or one or more

                                       24

Predecessor Securities) is registered at the close of business on the Regular
Record Date for such interest, which shall be the March 1 or September 1
(whether or not a Business Day), as the case may be, next preceding such
Interest Payment Date. Any such interest not so punctually paid or duly provided
for will forthwith cease to be payable to the Holder on such Regular Record Date
and may either be paid to the Person in whose name this Security (or one or more
Predecessor Securities) is registered at the close of business on a Special
Record Date for the payment of such Defaulted Interest to be fixed by the
Trustee, notice whereof shall be given to Holders of Securities not less than
10 days prior to such Special Record Date, or be paid at any time in any other
lawful manner not inconsistent with the requirements of any securities exchange
on which the Securities may be listed, and upon such notice as may be required
by such exchange, all as more fully provided in said Indenture.

    In accordance with the terms of the Registration Rights Agreement (i) if the
Company fails to file an Exchange Offer Registration Statement with the
Commission on or prior to November 24, 2000, (ii) if the Exchange Offer
Registration Statement is not declared effective by the Commission on or prior
to January 23, 2001, (iii) if the Exchange Offer is not consummated on or before
the 30th business day after the Exchange Offer Registration Statement is
declared effective, (iv) if obligated to file the Shelf Registration Statement
and the Company fails to file the Shelf Registration Statement with the
Commission on or prior to the 60th day after such filing obligation arises,
(v) if obligated to file a Shelf Registration Statement and the Shelf
Registration Statement is not declared effective on or prior to the 90th day
after the obligation to file a Shelf Registration Statement arises, or (vi) if
the Exchange Offer Registration Statement or the Shelf Registration Statement,
as the case may be, is declared effective but thereafter ceases to be effective
or useable in connection with resales of the Transfer Restricted Securities, for
such time of non-effectiveness or non-usability (each, a "Registration
Default"), the Company agrees to pay to each Holder of Transfer Restricted
Securities affected thereby liquidated damages ("Liquidated Damages") in an
amount equal to $0.05 per week per $1,000 in principal amount of Transfer
Restricted Securities held by such Holder for each week or portion thereof that
the Registration Default continues for the first 90 day period immediately
following the occurrence of such Registration Default. The amount of the
Liquidated Damages shall increase by an additional $0.05 per week per $1,000 in
principal amount of Transfer Restricted Securities with respect to each
subsequent 90 day period until all Registration Defaults have been cured, up to
a maximum amount of Liquidated Damages of $0.50 per week per $1,000 in principal
amount of Transfer Restricted Securities. The Company shall not be required to
pay Liquidated Damages for more than one Registration Default at any given time.
Following the cure of all Registration Defaults, the accrual of Liquidated
Damages will cease.

    All accrued Liquidated Damages shall be paid by the Company to Holders
entitled thereto by wire transfer to the accounts specified by them or by
mailing checks to their registered address if no such accounts have been
specified.

    The Holder of this Security is entitled to the benefits of such Registration
Rights Agreement.

    Payment of the principal of (and premium, if any) and any interest on this
Security will be made at the office or agency of the Company maintained for that
purpose in the Borough of Manhattan, The City of New York, in such coin or
currency of the United States of America as at the time of payment is legal
tender for payment of public and private debts; PROVIDED, HOWEVER, that at the
option of the Company payment of interest may be made by check mailed to the
address of the Person entitled thereto as such address shall appear in the
Security Register.

Section 2.03.  FORM OF REVERSE OF SECURITY.

    This Security is one of a duly authorized issue of Securities of the Company
designated as its Senior Notes due 2010 (herein called the "Securities"),
limited in aggregate principal amount at Stated Maturity to $400,000,000, issued
and to be issued under an Indenture, dated as of July 27, 2000 (herein called
the "Indenture", which term shall have the meaning assigned to it in such
instrument), between the Company and The Bank of New York, as Trustee (herein

Indenture), and reference is hereby made to the Indenture for a statement of the
respective rights, limitations of rights, duties and immunities thereunder of

    In addition, in the event of one or more sales by the Company on or prior to
March 15, 2003 of at least $75.0 million of its Capital Stock (other than
Redeemable Stock), the Company may redeem up to 35% of the aggregate principal
amount of the Securities originally issued with the proceeds of such sale at a
Redemption Price equal to 111% of such principal amount on the Redemption Date,
plus accrued and unpaid interest and Liquidated Damages, if any thereon, to the
Redemption Date; provided that at least 65% of the aggregate principal amount of
the Securities originally issued remain outstanding immediately after the
occurrence of any such redemption (excluding Securities held by the Company and
its Restricted Subsidiaries); and provided, further, that such redemption occurs
within 60 days after consummation of any such sale.

    The Securities do not have the benefit of any sinking fund obligations.

    In the event of redemption, or purchase pursuant to an Offer to Purchase, of
this Security in part only, a new Security or Securities for the unredeemed or
unpurchased portion hereof will be issued in the name of the Holder hereof upon
the cancellation hereof.

                                       26
<PAGE>
    The Indenture contains provisions for defeasance at any time of the entire
indebtedness of this Security or certain restrictive covenants and Events of
Default with respect to this Security, in each case upon compliance with certain
conditions set forth in the Indenture.

    If an Event of Default shall occur and be continuing, there may be declared
due and payable the Default Amount of the Securities, in the manner and with the
effect provided in the Indenture. The Default Amount in respect of this Security
as of any particular date shall equal 100% of the principal amount payable in
respect of this Security at the Stated Maturity hereof. Upon payment of (i) the
Default Amount so declared due and payable and any overdue installment of
interest in respect of this Security, (ii) any overdue principal or premium
payable on redemption or repurchase of this Security and (iii) as provided on
the face hereof, any interest on any overdue Default Amount, principal, premium
or interest in respect of this Security (to the extent that the payment of such
interest shall be legally enforceable), all of the Company's obligations in
respect of the payment of the principal of and any premium and interest on this
Security shall terminate.

    The Indenture provides that, subject to certain conditions, if a Change of
Control occurs, the Company shall be required to make an Offer to Purchase for
all of the Securities.

    Unless the context otherwise requires, references herein to the principal
amount of any Security mean, as of any day, (i) with respect to any portion
thereof required hereunder to be redeemed or repurchased on any redemption or
repurchase date on or prior to such day, the amount due and payable in respect
of such portion upon such redemption or repurchase date (excluding premium and
interest), (ii) with respect to any portion thereof not required to be so
redeemed or repurchased, but which has been declared due and payable prior to
the Stated Maturity thereof as provided in the Indenture, the Default Amount in
respect of such portion as of such day and (iii) with respect to any portion
thereof not required so to be redeemed or repurchased and not so declared due
and payable, such portion of the principal amount of such Security payable at
Stated Maturity thereof.

    The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders of the Securities under the Indenture at
any time by the Company and the Trustee after having received the Required
Consent (defined as follows). The Indenture also contains provisions permitting
those Persons giving the Required Consent, on behalf of the Holders of all the
Securities, to waive compliance by the Company with certain provisions of the
Indenture and certain past defaults under the Indenture and their consequences.
Any such consent or waiver by the Holder of this Security shall be conclusive
and binding upon such Holder and upon all future Holders of this Security and of
any Security issued upon the registration of transfer hereof or in exchange
herefor or in lieu hereof, whether or not notation of such consent or waiver is
made upon this Security.

    As used herein, "Required Consent" means, except as otherwise expressly
provided in the Indenture with respect to matters requiring the consent of each
holder of Securities (including Additional Securities) affected thereby, the
consent of holders of not less than a majority in aggregate principal amount at
Stated Maturity of the Securities (including Additional Securities).

    As provided in and subject to the provisions of the Indenture, the Holder of
this Security shall not have the right to institute any proceeding with respect
to the Indenture or for the appointment of a receiver or trustee or for any
other remedy thereunder, unless such Holder shall have previously given the
Trustee written notice of a continuing Event of Default with respect to the
Securities, the Holders of not less than a majority in principal amount at
Stated Maturity of the Securities at the time Outstanding shall have made
written request to the Trustee to institute proceedings in respect of such Event
of Default as Trustee and offered the Trustee indemnity satisfactory to the
Trustee and the Trustee shall not have received from the Holders of a majority
in principal amount at Stated Maturity of Securities at the time Outstanding a
direction inconsistent with such request, and shall have failed to institute any
such proceeding, within 60 days after receipt of such notice, request and offer
of indemnity. The foregoing shall

                                       27
<PAGE>
not apply to certain suits described in the Indenture, including any suit
instituted by the Holder of this Security for the enforcement of any payment of
principal hereof or any premium or interest hereon on or after the respective
due dates expressed herein (or, in the case of redemption, on or after the
Redemption Date or, in the case of any purchase of this Security required to be
made pursuant to an Offer to Purchase, on or after the Purchase Date.)

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

    As provided in the Indenture and subject to certain limitations therein set
forth, the transfer of this Security is registrable in the Security Register,
upon surrender of this Security for registration of transfer at the office or
agency of the Company in the Borough of Manhattan, The City of New York, duly
endorsed by, or accompanied by a written instrument of transfer in form
satisfactory to the Company and the Security Registrar duly executed by, the
Holder hereof or his attorney duly authorized in writing, and thereupon one or
more new Securities, of authorized denominations and for the same aggregate
principal amount, will be issued to the designated transferee or transferees.

    The Securities are issuable only in registered form without coupons in
denominations of $1,000 and any integral multiple thereof. As provided in the
Indenture and subject to certain limitations therein set forth, the Securities
are exchangeable for a like aggregate principal amount of Securities of like

                                 THE SECURITIES

Section 3.01.  TITLE AND TERMS.

    The aggregate principal amount at Stated Maturity of Securities which may be
authenticated and delivered under this Indenture is limited to $400,000,000 of
which $200,000,000 will be issued on the date hereof, except for Securities

for, or in lieu of, other Securities pursuant to Section 3.04, 3.05, 3.08, 9.06
or 11.08 or in connection with an Offer to Purchase pursuant to Section 10.13.

    The Securities shall be known and designated as the "Senior Notes due 2010"
of the Company. Their Stated Maturity shall be March 15, 2010 and they shall
bear cash interest at the rate of 11% per annum, from July 27, 2000 or from the
most recent Interest Payment Date to which interest has been paid or duly
provided for, as the case may be, payable semi-annually on March 15 and
September 15, commencing September 15, 2000 until the principal thereof is paid
or made available for payment.

    The principal of (and premium, if any) and interest on the Securities shall
be payable at the office or agency of the Company in the Borough of Manhattan,
The City of New York maintained for such purpose and at any other office or
agency maintained by the Company for such purpose; PROVIDED, HOWEVER, that at
the option of the Company, payment of interest may be made by check mailed to
the address of the Person entitled thereto as such address shall appear in the
Security Register.

    The Company may be required to make an Offer to Purchase the Securities as
provided in Section 10.13.

    The Securities shall be redeemable as provided in Article 2 and Article 11.

    The Securities shall be subject to Defeasance and/or Covenant Defeasance as
provided in Article 12.

Section 3.02.  DENOMINATIONS.

    The Securities shall be issuable only in registered form without coupons and
only in denominations of $1,000 principal amount and any integral multiple
thereof.

Section 3.03.  EXECUTION, AUTHENTICATION, DELIVERY AND DATING.

    The Securities shall be executed on behalf of the Company by its Chairman of
the Board, its President or one of its Vice Presidents. The signature of any of
these officers on the Securities may be manual or facsimile.

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

    At any time and from time to time after the execution and delivery of this
Indenture, the Company may deliver Securities executed by the Company to the
Trustee for authentication, together with a Company Order for the authentication
and delivery of such Securities; and the Trustee in accordance with

                                       33
<PAGE>
such Company Order shall authenticate and deliver such Securities as in this
Indenture provided and not otherwise.

    Each Security shall be dated the date of its authentication.

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

Section 3.04.  TEMPORARY SECURITIES.

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

    If temporary Securities are issued, the Company will cause definitive
Securities to be prepared without unreasonable delay. After the preparation of
definitive Securities, the temporary Securities shall be exchangeable for
definitive Securities upon surrender of the temporary Securities at any office
or agency of the Company designated pursuant to Section 10.02, without charge to
the Holder. Upon surrender for cancellation of any one or more temporary
Securities the Company shall execute and the Trustee shall authenticate and
deliver in exchange therefor a like principal amount of definitive Securities of
authorized denominations and of a like tenor. Until so exchanged the temporary
Securities shall in all respects be entitled to the same benefits under this
Indenture as definitive Securities.

Section 3.05.  REGISTRATION, REGISTRATION OF TRANSFER AND EXCHANGE.

    The Company shall cause to be kept at the Corporate Trust Office of the
Trustee a register (the register maintained in such office and in any other
office or agency designated pursuant to Section 10.02 being herein sometimes
collectively referred to as the "Security Register") in which, subject to such
reasonable regulations as it may prescribe, the Company shall provide for the
registration of Securities and of transfers of Securities. The Trustee is hereby
appointed "Security Registrar" for the purpose of registering Securities and
transfers of Securities as herein provided.

    Upon surrender for registration of transfer of any Security at an office or
agency of the Company designated pursuant to Section 10.02 for such purpose, the
Company shall execute, and the Trustee shall authenticate and deliver, in the
name of the designated transferee or transferees, one or more new Securities of
any authorized denominations and of a like aggregate principal amount and tenor.
No such transfer shall be effected until, and such transferee shall succeed to
the rights of a Holder only upon, final acceptance and registration of the
transfer by the Security Registrar in the Security Register. Prior to the
registration of any transfer by a Holder as provided herein, the Company, the
Trustee and any agent of the Company shall treat the person in whose name the
Security is registered as the owner thereof for all purposes whether or not the
Security shall be overdue, and neither the Company, the Trustee, nor any such
agent shall be affected by notice to the contrary. Furthermore, any Holder of a
Global Security shall, by acceptance of such Global Security, agree that
transfers of beneficial interests in such Global Security may be effected only
through a book entry system maintained by the Holder of such Global Security (or
its agent) and that ownership of a beneficial interest in the Security shall be
required to be reflected in a book entry.

                                       34
<PAGE>
    At the option of the Holder, Securities may be exchanged for other
Securities (including an exchange of securities for Exchange Securities) of any
authorized denominations and of a like aggregate principal amount and tenor,
upon surrender of the Securities to be exchanged at such office or agency
PROVIDED, that no exchange of Securities for Exchange Securities shall occur
until a Registration Statement shall have been declared effective by the
Commission and that Securities that are exchanged for Exchange Securities
pursuant to such Registration Statement shall be canceled by the Trustee.
Whenever any Securities are so surrendered for exchange, the Company shall
execute, and the Trustee shall authenticate and deliver, the Securities which
the Holder making the exchange is entitled to receive.

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

    Every Security presented or surrendered for registration of transfer or for
exchange shall (if so required by the Company or the Trustee) be duly endorsed,
or be accompanied by a written instrument of transfer in form satisfactory to
the Company and the Security Registrar duly executed, by the Holder thereof or
his attorney duly authorized in writing.

    No service charge shall be made for any registration of transfer or exchange
of Securities, but the Company may require payment of a sum sufficient to cover
any tax or other governmental charge that may be imposed in connection with any
registration of transfer or exchange of Securities, other than exchanges
pursuant to Section 3.04, 9.06 or 11.08 or in accordance with any Offer to
Purchase pursuant to Section 10.13, and in any such case not involving any
transfer.

    The Company shall not be required (i) to issue, register the transfer of or
exchange any Security during a period beginning at the opening of business
15 days before the day of the mailing of a notice of redemption of Securities
selected for redemption under Section 11.04 and ending at the close of business
on the day of such mailing, or (ii) to register the transfer of or exchange any
Security so selected for redemption in whole or in part, except the unredeemed
portion of any Security being redeemed in part.

Section 3.06.  BOOK-ENTRY PROVISIONS FOR GLOBAL SECURITY.

    (a)  The Global Security initially shall (i) be registered in the name of
the Depository for such Global Security or the nominee of such Depository;
(ii) be delivered to the Trustee as custodian for such Depository; and
(iii) bear legends as set forth in Section 2.05.

    Members of, or participants in, the Depository ("Agent Members") shall have
no rights under this Indenture with respect to any Global Security held on their
behalf by the Depository, or the Trustee as its custodian, or under the Global
Security and the Depository may be treated by the Company, the Trustee and any
agent of the Company or the Trustee as the absolute owner of such Global
Security for all purposes whatsoever. Notwithstanding the foregoing, nothing
herein shall prevent the Company, the Trustee or any agent of the Company or the
Trustee, from giving effect to any written certification, proxy or other
authorization furnished by the Depository or impair, as between the Depository
and its Agent Members, the operation of customary practices governing the
exercise of the rights of a holder of any Security.

    (b)  Transfers of a Global Security shall be limited to transfers of such
Global Security in whole, but not in part, to the Depository, its successors or
their respective nominees. Interests of beneficial owners in a Global Security
may be transferred in accordance with the rules and procedures of the Depository
and the provisions of Section 3.07. In addition, U.S. Physical Securities and
Offshore Physical Securities shall be transferred to all beneficial owners in
exchange for their beneficial interests in the U.S. Global Securities or
Offshore Global Securities, respectively, if (i) the Depository notifies the
Company that it is unwilling or unable to continue as Depository for the U.S.
Global Securities or Offshore Global Securities, as the case may be, and a
successor depository is not appointed by the Company within 90 days of such

                                       35
<PAGE>
notice, (ii) an Event of Default has occurred and is continuing and the Security
Registrar has received a request therefor from the Depository or (iii) in
accordance with the rules and procedures of the Depository and the provisions of
Section 3.07.

    (c)  In connection with any transfer of a portion of the beneficial
interests in the Global Security to beneficial owners pursuant to paragraph (b)
of this Section, the Security Registrar shall reflect on the Security Register
the date and a decrease in the principal amount of the Global Security in an
amount equal to the principal amount of the beneficial interest in the Global
Security to be transferred, and the Company shall execute, and the Trustee shall
authenticate and deliver, one or more Physical Securities of like tenor and
amount.

    (d)  In connection with the transfer of an entire U.S. Global Security or
Offshore Global Security to beneficial owners pursuant to paragraph (b) of this
Section, such U.S. Global Security or Offshore Global Security shall be deemed
to be surrendered to the Trustee for cancellation, and the Company shall
execute, and the Trustee shall authenticate and deliver, to each beneficial
owner identified by the Depository in exchange for its beneficial interest in
such U.S. Global Security or Offshore Global Security, as the case may be, an
equal aggregate principal amount of U.S. Physical Securities or Offshore
Physical Securities of authorized denominations.

    (e)  Any Physical Security delivered in exchange for an interest in the
Global Security pursuant to paragraph (b), (c) or (d) of this Section shall,
except as otherwise provided by paragraph (d) of Section 3.07 bear the legend
regarding transfer restrictions applicable to the Physical Securities set forth
in Section 2.05.

    (f)  The registered holder of a Global Security may grant proxies and
otherwise authorize any person, including Agent Members and persons that may
hold interests through Agent Members, to take any action which a Holder is
entitled to take under this Indenture or the Securities.

    stating, or has otherwise advised the Company and the Security Registrar in
    writing, that the sale has been made in compliance with the provisions of

        (i)  The Security Registrar shall register the transfer of any Security,
    whether or not such Security bears the Private Placement Legend, if (x) the

        (ii)  If the proposed transferor is an Agent Member holding a beneficial
    interest in the U.S. Global Security, upon receipt by the Security Registrar
    of (x) the documents, if any, required by the preceding paragraph (i), and
    (y) instructions given in accordance with the Depositary's and the Security
    Registrar's procedures, the Security Registrar shall reflect on its books
    and records the date and a decrease in the principal amount of the U.S.
    Global Security in an amount equal to the principal amount of the beneficial
    interest in the U.S. Global Security to be transferred, and the Company
    shall execute, and the Trustee shall authenticate and deliver, one or more
    U.S. Physical Securities of like tenor and amount.

    (c)  TRANSFERS OF INTERESTS IN THE OFFSHORE GLOBAL SECURITIES OR OFFSHORE

Securities:

        (i)  prior to removal of the Private Placement Legend from an Offshore

    be; and

        (ii)  after such removal, the Security Registrar shall register the
    transfer of any such Security without requiring any additional
    certification.

        (i)  The Security Registrar shall register any proposed transfer to any

    Security or an interest in a U.S. Global Security only upon receipt of a
    certificate substantially in the form of Exhibit C hereto from the proposed
    transferor.

        (ii)  (A) If the proposed Transferor is an Agent Member holding a
    beneficial interest in a U.S. Global Security, upon receipt by the Security
    Registrar of (x) the documents required by paragraph (i) and

    Registrar's procedures, the Security Registrar shall reflect on its books

    Security Registrar's procedures, the Security Registrar shall reflect on its

                                       37
<PAGE>
    records the date and an increase in the principal amount of the Offshore

    Physical Securities or the U.S. Global Security, as the case may be, to be
    transferred, and the Trustee shall cancel the Physical Security, if any, so
    transferred or decrease the amount of the U.S. Global Security.

    (e)  PRIVATE PLACEMENT LEGEND. Upon the transfer, exchange or replacement of
Securities not bearing the Private Placement Legend, the Security Registrar
shall deliver Securities that do not bear the Private Placement Legend. Upon the
transfer, exchange or replacement of securities bearing the Private Placement
Legend, the Security Registrar shall deliver only Securities that bear the
Private Placement Legend unless either (i) the circumstances contemplated by
Section 2.05 exist or (ii) there is delivered to the Trustee an Opinion of
Counsel reasonably satisfactory to the Company and the Trustee to the effect
that neither such legend nor the related restrictions on transfer are required
in order to maintain compliance with the provisions of the Securities Act.

    (f)  GENERAL. By its acceptance of any Security bearing the Private
Placement Legend, each Holder of such a Security acknowledges the restrictions
on transfer of such Security set forth in this Indenture and in the Private
Placement Legend and agrees that it will transfer such Security only as provided
in this Indenture. The Security Registrar shall not register a transfer of any
Security unless such transfer complies with the restrictions on transfer of such
Security set forth in the Private Placement Legend and in this Indenture. In
connection with any transfer of Securities, each Holder agrees by its acceptance
of the Securities to furnish the Trustee or the Company such certifications,
legal opinions or other information as either of them may reasonably require to
confirm that such transfer is being made pursuant to an exemption from, or a
transaction not subject to, the registration requirements of the Securities Act;
PROVIDED that the Trustee shall not be required to determine (but may rely on a
determination made by the Company with respect to) the sufficiency of any such
certifications, legal opinions or other information.

    The Trustee shall retain copies of all letters, notices and other written
communications received pursuant to Section 3.06 or this Section 3.07. The
Company shall have the right to inspect and make copies of all such letters,
notices or other written communications at any reasonable time upon the giving
of reasonable written notice to the Trustee.

Section 3.08.  MUTILATED, DESTROYED, LOST AND STOLEN SECURITIES.

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

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

    In case any such mutilated, destroyed, lost or stolen Security has become or
is about to become due and payable, the Company in its discretion may, instead
of issuing a new Security, pay such Security.

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

    Every new Security issued pursuant to this Section in lieu of any destroyed,
lost or stolen Security shall constitute an original additional contractual
obligation of the Company, whether or not the destroyed, lost

                                       38
<PAGE>
or stolen Security shall be at any time enforceable by anyone, and shall be
entitled to all the benefits of this Indenture equally and proportionately with
any and all other Securities duly issued hereunder.

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

Section 3.09.  PAYMENT OF INTEREST; INTEREST RIGHTS PRESERVED.

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

    Any interest on any Security which is payable, but is not punctually paid or
duly provided for, on any Interest Payment Date (herein called "Defaulted
Interest") shall forthwith cease to be payable to the Holder on the relevant
Regular Record Date by virtue of having been such Holder, and such Defaulted
Interest may be paid by the Company, at its election in each case, as provided
in Clause (1) or (2) below:

        (1)  The Company may elect to make payment of any Defaulted Interest to
    the Persons in whose names the Securities (or their respective Predecessor
    Securities) are registered at the close of business on a Special Record Date
    for the payment of such Defaulted Interest, which shall be fixed in the
    following manner. The Company shall notify the Trustee in writing of the
    amount of Defaulted Interest proposed to be paid on each Security and the
    date of the proposed payment, and at the same time the Company shall deposit
    with the Trustee an amount of money equal to the aggregate amount proposed
    to be paid in respect of such Defaulted Interest or shall make arrangements
    satisfactory to the Trustee for such deposit prior to the date of the
    proposed payment, such money when deposited to be held in trust for the
    benefit of the Persons entitled to such Defaulted Interest as in this Clause
    provided. Thereupon the Trustee shall fix a Special Record Date for the
    payment of such Defaulted Interest which shall be not more than 15 days and
    not less than 10 days prior to the date of the proposed payment and not less
    than 10 days after the receipt by the Trustee of the notice of the proposed
    payment. The Trustee shall promptly notify the Company of such Special
    Record Date and, in the name and at the expense of the Company, shall cause
    notice of the proposed payment of such Defaulted Interest and the Special
    Record Date therefor to be given to each Holder in the manner specified in
    Section 1.06, not less than 10 days prior to such Special Record Date.
    Notice of the proposed payment of such Defaulted Interest and the Special
    Record Date therefor having been so mailed, such Defaulted Interest shall be
    paid to the Persons in whose names the Securities (or their respective
    Predecessor Securities) are registered at the close of business on such
    Special Record Date and shall no longer be payable pursuant to the following
    Clause (2).

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

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

Section 3.10.  PERSONS DEEMED OWNERS.

    Prior to due presentment of a Security for registration of transfer, the
Company, the Trustee and any agent of the Company or the Trustee may treat the
Person in whose name such Security is registered as the owner of such Security
for the purpose of receiving payment of principal of (and premium, if any) and
(subject to Section 3.09) interest on such Security and for all other purposes
whatsoever, whether or not

                                       39
<PAGE>
such Security be overdue, and neither the Company, the Trustee nor any agent of
the Company or the Trustee shall be affected by notice to the contrary.

Section 3.11.  CANCELLATION.

    All Securities surrendered for payment, redemption, registration of transfer
or exchange or for credit against any Offer to Purchase pursuant to
Section 10.13 shall, if surrendered to any Person other than the Trustee, be
delivered to the Trustee and shall be promptly canceled by it. The Company may
at any time deliver to the Trustee for cancellation any Securities previously
authenticated and delivered hereunder which the Company may have acquired in any
manner whatsoever, and all Securities so delivered shall be promptly canceled by
the Trustee. No Securities shall be authenticated in lieu of or in exchange for
any Securities canceled as provided in this Section, except as expressly
permitted by this Indenture. All canceled Securities held by the Trustee shall
be disposed of as directed by a Company Order; PROVIDED, HOWEVER, that the
Trustee shall not be required to destroy canceled Securities.

Section 3.12.  COMPUTATION OF INTEREST.

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

Section 3.13.  CUSIP, CINS AND ISIN NUMBERS.

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

Section 4.01.  SATISFACTION AND DISCHARGE OF INDENTURE.

    This Indenture shall cease to be of further effect (except as to any
surviving rights of registration of transfer or exchange of Securities herein
expressly provided for), and the Trustee, on demand of and at the expense of the
Company, shall execute proper instruments acknowledging satisfaction and
discharge of this Indenture, when

        (1) either

           (A) all Securities theretofore authenticated and delivered (other
       than (i) Securities which have been destroyed, lost or stolen and which
       have been replaced or paid as provided in Section 3.08 and
       (ii) Securities for whose payment money has theretofore been deposited in
       trust or segregated and held in trust by the Company and thereafter
       repaid to the Company or discharged from such trust, as provided in
       Section 10.03) have been delivered to the Trustee for cancellation; or

           (B) all such Securities not theretofore delivered to the Trustee for
       cancellation

               (i) have become due and payable, or

               (ii) will become due and payable at their Stated Maturity within
           one year, or

               (iii) are to be called for redemption within one year under
           arrangements satisfactory to the Trustee for the giving of notice of
           redemption by the Trustee in the name, and at the expense, of the
           Company,

           and the Company, in the case of (i), (ii) or (iii) above, has
           deposited or caused to be deposited with the Trustee as trust funds
           in trust for the purpose an amount sufficient to pay and discharge
           the entire indebtedness on such Securities not theretofore delivered
           to the Trustee for cancellation, for principal (and premium, if any)
           and interest to the date of such deposit (in the case of Securities
           which have become due and payable) or to the Stated Maturity or
           Redemption Date, as the case may be;

        (2) the Company has paid or caused to be paid all other sums payable
    hereunder by the Company; and

        (3) the Company has delivered to the Trustee an Officers' Certificate
    and an Opinion of Counsel, each stating that all conditions precedent herein
    provided for relating to the satisfaction and discharge of this Indenture

Notwithstanding the satisfaction and discharge of this Indenture pursuant to
this Article 4, the obligations of the Company to the Trustee under
Section 6.07, the obligations of the Trustee to any Authenticating Agent under
Section 6.14 and, if money shall have been deposited with the Trustee pursuant

(including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Persons entitled thereto, of

                                       41
<PAGE>
the principal (and premium, if any) and interest for whose payment such money
has been deposited with the Trustee.

Section 5.02.  ACCELERATION OF MATURITY; RESCISSION AND ANNULMENT.

    If an Event of Default (other than an Event of Default specified in
Section 5.01(8) or (9)) occurs and is continuing, then and in every such case
the Trustee or the Holders of not less than 25% in aggregate principal amount at
Stated Maturity of the Outstanding Securities may declare the Default Amount of
all the Securities to be due and payable immediately, by a notice in writing to
the Company (and to the Trustee if given by Holders), and upon any such
declaration such Default Amount and any accrued interest shall become
immediately due and payable. If an Event of Default specified in
Section 5.01(8) or (9) occurs, the Default Amount of and any accrued interest on
the Securities then Outstanding shall IPSO FACTO become immediately due and
payable without any declaration or other Act on the part of the Trustee or any
Holder.

    The Default Amount in respect of any particular Security as of any
particular date shall equal 100% of the principal amount payable in respect of
the Security at the Stated Maturity thereof.

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

        (1) the Company has paid or deposited with the Trustee a sum sufficient
    to pay

           (A) all overdue interest on all Securities (without duplication of
       any amount thereof paid or deposited pursuant to Clause (B) or
       (C) below),

           (B) the principal of (and premium, if any, on) any Securities which
       have become due otherwise than by such declaration of acceleration
       (including any Securities required to have been purchased on the Purchase
       Date pursuant to an Offer to Purchase made by the Company) and, to the
       extent that payment of such interest is lawful, interest thereon at the
       rate provided by the Securities (without duplication of any amount
       thereof paid or deposited pursuant to Clause (A) above or Clause (C)
       below),

                                       43
<PAGE>
           (C) to the extent that payment of such interest is lawful, interest
       upon overdue interest at the rate provided by the Securities (without
       duplication of any amount thereof paid or deposited pursuant to
       Clause (A) or (B) above), and

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

    and

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

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

    Unless the context otherwise requires, references in this Indenture to the
principal amount of any Security mean, as of any day, (i) with respect to any
portion thereof required thereunder to be redeemed or repurchased on any
redemption or repurchase date on or prior to such day, the amount due and
payable in respect of such portion upon such redemption or repurchase date
(excluding premium and interest), (ii) with respect to any portion thereof not
required to be so redeemed or repurchased, but which has been declared due and
payable prior to the Stated Maturity thereof, the Default Amount in respect of
such portion as of such day and (iii) with respect to any portion thereof not
required so to be redeemed or repurchased and not so declared due and payable,
such portion of the principal amount of such Security payable at Stated Maturity
thereof.

Section 5.03.  COLLECTION OF INDEBTEDNESS AND SUITS FOR ENFORCEMENT BY TRUSTEE.

    The Company covenants that if

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

        (2) default is made in the payment of the principal of (or premium, if
    any, on) any Security at the Maturity thereof or, with respect to any
    Security required to have been purchased pursuant to an Offer to Purchase
    made by the Company, at the Purchase Date thereof,

the Company will, upon demand of the Trustee, pay to the Trustee, for the
benefit of the Holders of such Securities, the whole amount then due and payable
on such Securities for principal (and premium, if any) and interest, and, to the
extent that payment of such interest shall be legally enforceable, interest on
any overdue principal (and premium, if any) and on any overdue interest, at the
rate provided by the Securities, and, in addition thereto, such further amount
as shall be sufficient to cover the costs and expenses of collection, including
the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel.

    If an Event of Default occurs and is continuing, the Trustee may in its
discretion proceed to protect and enforce its rights and the rights of the
Holders by such appropriate judicial proceedings as the Trustee shall deem most
effectual to protect and enforce any such rights, whether for the specific
enforcement of any covenant or agreement in this Indenture or in aid of the

obligor upon the Securities), its property or its creditors, the Trustee shall
be entitled and empowered, by intervention in such proceeding or otherwise, to
take any and all actions authorized under the Trust Indenture Act in order to
have claims of the Holders and the Trustee allowed in any such proceeding. In
particular, the Trustee shall

                                       44

be authorized to collect and receive any moneys or other property payable or
deliverable on any such claims and to distribute the same; and any custodian,
receiver, assignee, trustee, liquidator, sequestrator or other similar official
in any such judicial proceeding is hereby authorized by each Holder to make such
payments to the Trustee and, in the event that the Trustee shall consent to the
making of such payments directly to the Holders, to pay to the Trustee any
amount due it for the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel, and any other amounts due the
Trustee under Section 6.07.

    No provision of this Indenture shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder any plan of
reorganization, arrangement, adjustment or composition affecting the Securities
or the rights of any Holder thereof or to authorize the Trustee to vote in
respect of the claim of any Holder in any such proceeding; provided, however,
that the Trustee may, on behalf of the Holders, vote for the election of a
trustee in bankruptcy or similar official and be a member of a creditors' or
other similar committee.

Section 5.05.  TRUSTEE MAY ENFORCE CLAIMS WITHOUT POSSESSION OF SECURITIES.

    All rights of action and claims under this Indenture or the Securities may
be prosecuted and enforced by the Trustee without the possession of any of the
Securities or the production thereof in any proceeding relating thereto, and any
such proceeding instituted by the Trustee shall be brought in its own name as
trustee of an express trust, and any recovery of judgment shall, after provision
for the payment of the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel, be for the ratable benefit of
the Holders of the Securities in respect of which such judgment has been
recovered.

Section 5.06.  APPLICATION OF MONEY COLLECTED.

in the following order, at the date or dates fixed by the Trustee and, in case
of the distribution of such money on account of principal (or premium, if any)
or interest, upon presentation of the Securities and the notation thereon of the
payment if only partially paid and upon surrender thereof if fully paid:

        FIRST:  To the payment of all amounts due the Trustee under
    Section 6.07; and

        SECOND:  To the payment of the amounts then due and unpaid for principal
    of (and premium, if any) and interest on the Securities in respect of which
    or for the benefit of which such money has been collected, ratably, without
    preference or priority of any kind, according to the amounts due and payable
    on such Securities for principal (and premium, if any) and interest,
    respectively.

Section 5.07.  LIMITATION ON SUITS.

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

        (1) such Holder has previously given written notice to a Responsible
    Officer of the Trustee of a continuing Event of Default;

        (2) the Holders of a majority in aggregate principal amount at Stated
    Maturity of the Outstanding Securities shall have made written request to a
    Responsible Officer of the Trustee to institute proceedings in respect of
    such Event of Default in its own name as Trustee hereunder;

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

                                       45
<PAGE>
        (4) the Trustee for 60 days after its receipt of such notice, request
    and offer of indemnity has failed to institute any such proceeding; and

        (5) no direction inconsistent with such written request has been given
    to the Trustee during such 60-day period by the Holders of a majority in
    principal amount at Stated Maturity of the Outstanding Securities;

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

Section 5.08.  UNCONDITIONAL RIGHT OF HOLDERS TO RECEIVE PRINCIPAL, PREMIUM AND
  INTEREST.

    Notwithstanding any other provision in this Indenture, the Holder of any
Security shall have the right, which is absolute and unconditional, to receive
payment of the principal of (and premium, if any) and (subject to Section 3.09)
interest on such Security on the respective Stated Maturities expressed in such
Security (or, in the case of redemption, on the Redemption Date or in the case
of an Offer to Purchase made by the Company and required to be accepted as to
such Security, on the Purchase Date) and to institute suit for the enforcement
of any such payment, and such rights shall not be impaired without the consent
of such Holder.

Section 5.09.  RESTORATION OF RIGHTS AND REMEDIES.

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

Section 5.10.  RIGHTS AND REMEDIES CUMULATIVE.

    Except as otherwise provided with respect to the replacement or payment of
mutilated, destroyed, lost or stolen Securities in the last paragraph of
Section 3.08, no right or remedy herein conferred upon or reserved to the
Trustee or to the Holders is intended to be exclusive of any other right or
remedy, and every right and remedy shall, to the extent permitted by law, be
cumulative and in addition to every other right and remedy given hereunder or
now or hereafter existing at law or in equity or otherwise. The assertion or
employment of any right or remedy hereunder, or otherwise, shall not prevent the
concurrent assertion or employment of any other appropriate right or remedy.

Section 5.11.  DELAY OR OMISSION NOT WAIVER.

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

    By giving the Required Consent, those Persons giving the Required Consent
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 that

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

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

Section 5.13.  WAIVER OF PAST DEFAULTS.

    By giving the Required Consent, those Persons giving the Required Consent
may, on behalf of the Holders of all the Securities, waive any past default
hereunder and its consequences, except a default

    on any Security (including any Security which is required to have been
    purchased pursuant to an Offer to Purchase which has been made by the
    Company), or

        (2) in respect of a covenant or provision hereof which under Article 9
    cannot be modified or amended without the consent of the Holder of each
    Outstanding Security affected.

    Upon any such waiver, such default shall cease to exist, and any Event of
Default arising therefrom shall be deemed to have been cured, for every purpose
of this Indenture; but no such waiver shall extend to any subsequent or other
default or impair any right consequent thereon.

Section 5.14.  UNDERTAKING FOR COSTS.

    In any suit for the enforcement of any right or remedy under this Indenture,
or in any suit against the Trustee for any action taken, suffered or omitted by
it as Trustee, a court may require any party litigant in such suit to file an
undertaking to pay the costs of such suit, and may assess costs against any such
party litigant, in the manner and to the extent provided in the Trust Indenture
Act; PROVIDED, that neither this Section nor the Trust Indenture Act shall be
deemed to authorize any court to require such an undertaking or to make such an
assessment in any suit instituted by the Company.

Section 5.15.  WAVIER OF STAY OF EXTENSION LAWS.

    The Company covenants (to the extent that it may lawfully do so) that it
will not at any time insist upon, or plead, or in any manner whatsoever claim or
take the benefit or advantage of, any usury, stay or extension law wherever
enacted, now or at any time hereafter in force, which may affect the covenants
or the performance of this Indenture; and the Company (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such law
and covenants that it will not hinder, delay or impede the execution of any
power herein granted to the Trustee, but will suffer and permit the execution of
every such power as though no such law had been enacted.

    The duties and responsibilities of the Trustee shall be as provided by the
Trust Indenture Act. 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 therein
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 Section.

    to act hereunder; and

        (k) the Trustee may request that the Company deliver an Officers'
    Certificate setting forth the names of individuals and/or titles of officers
    authorized at such time to take specified actions pursuant to this
    Indenture, which Officers' Certificate may be signed by any person
    authorized to sign an Officers' Certificate, including any person specified
    as so authorized in any such certificate previously delivered and not
    superseded.

Section 6.04.  NOT RESPONSIBLE FOR RECITALS OR ISSUANCE OF SECURITIES.

    The recitals contained herein and in the Securities, except the Trustee's
certificates of authentication, shall be taken as the statements of the Company,
and the Trustee assumes no responsibility for their correctness. The Trustee

of the Securities. The Trustee shall not be accountable for the use or
application by the Company of Securities or the proceeds thereof.

Section 6.05.  MAY HOLD SECURITIES.

        (1) to pay to the Trustee from time to time such compensation as the
    Company and the Trustee shall from time to time agree in writing for all
    services rendered by it hereunder (which compensation

                                       49
<PAGE>

    of a trustee of an express trust);

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

        (3) to indemnify the Trustee and any predecessor Trustee for, and to

is eligible pursuant to the Trust Indenture Act to act as such and has a

Office in the Borough of Manhattan, The City of New York. If such Person
publishes reports of condition at least annually, pursuant to law or to the
requirements of said supervising or examining authority, then for the purposes
of this Section and to the extent permitted by the Trust Indenture Act, the
combined capital and surplus of such Person shall be deemed to be its combined
capital and surplus as set forth in its most recent report of condition so
published. If at any time the Trustee shall cease to be eligible in accordance
with the provisions of this Section, it shall resign immediately in the manner
and with the effect hereinafter specified in this Article.

Section 6.10.  RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR.

    (a) No resignation or removal of the Trustee and no appointment of a
successor Trustee pursuant to this Article shall become effective until the
acceptance of appointment by the successor Trustee in accordance with the
applicable requirements of Section 6.11.

    (b) The Trustee may resign at any time by giving written notice thereof to
the Company. If an instrument of acceptance by a successor Trustee in accordance
with the applicable requirements of Section 6.11 shall not have been delivered
to the Trustee within 30 days after the giving of such notice of

                                       50
<PAGE>
resignation, the resigning Trustee may petition any court of competent
jurisdiction for the appointment of a successor Trustee.

    (c) The Trustee may be removed at any time by Act of the Holders of a
majority in principal amount at Stated Maturity of the Outstanding Securities,
delivered to the Trustee and to the Company. If an instrument of acceptance by a
successor Trustee in accordance with the applicable requirements of
Section 6.11 shall not have been delivered to the Trustee within 30 days after

competent jurisdiction for the appointment of a successor Trustee.

    (d) If at any time:

        (2) the Trustee shall fail to comply with Section 6.08 after written
    request therefor by the Company or by any Holder who has been a bona fide
    Holder of a Security for at least six months, or

        (3) the Trustee shall cease to be eligible under Section 6.09 and shall
    fail to resign after written request therefor by the Company or by any such
    Holder, or

        (4) the Trustee shall become incapable of acting or shall be adjudged a
    bankrupt or insolvent or a receiver of the Trustee or of its property shall
    be appointed or any public officer shall take charge or control of the
    Trustee or of its property or affairs for the purpose of rehabilitation,
    conservation or liquidation,

then, in any such case, (i) the Company by a Board Resolution may remove the
Trustee, or (ii) subject to Section 5.14, any Holder who has been a bona fide
Holder of a Security for at least six months may, on behalf of himself and all
others similarly situated, petition any court of competent jurisdiction for the
removal of the Trustee and the appointment of a successor Trustee.

    (a) If the Trustee shall resign, be removed or become incapable of acting,
or if a vacancy shall occur in the office of Trustee for any cause, the Company,
by a Board Resolution, shall promptly appoint a successor Trustee. If, within
one year after such resignation, removal or incapability, or the occurrence of
such vacancy, a successor Trustee shall be appointed by Act of the Holders of a
majority in principal amount at Stated Maturity of the Outstanding Securities
delivered to the Company and the retiring Trustee, the successor Trustee so
appointed shall, forthwith upon its acceptance of such appointment in accordance
with the applicable requirements of Section 6.11, become the successor Trustee
and supersede the successor Trustee appointed by the Company. If no successor
Trustee shall have been so appointed by the Company or the Holders and accepted
appointment in accordance with the applicable requirements of Section 6.11, any
Holder who has been a bona fide Holder of a Security for at least six months
may, on behalf of himself and all others similarly situated, petition any court
of competent jurisdiction for the appointment of a successor Trustee.

    (b) The Company shall give notice of each resignation and each removal of
the Trustee and each appointment of a successor Trustee to all Holders in the
manner provided in Section 1.06. Each notice shall include the name of the
successor Trustee and the address of its Corporate Trust Office.

Section 6.11.  ACCEPTANCE OF APPOINTMENT BY SUCCESSOR.

    Every successor Trustee appointed hereunder shall execute, acknowledge and
deliver to the Company and to the retiring Trustee an instrument accepting such
appointment, and thereupon the resignation or removal of the retiring Trustee
shall become effective and such successor Trustee, without any further act, deed
or conveyance, shall become vested with all the rights, powers, trusts and
duties of the retiring Trustee; but, on request of the Company or the successor
Trustee, such retiring Trustee shall, upon payment of its charges, execute and
deliver an instrument transferring to such successor Trustee all the rights,
powers and trusts of the retiring Trustee and shall duly assign, transfer and
deliver to such successor Trustee all property and money held by such retiring
Trustee hereunder. Upon request of any such

                                       51
<PAGE>
successor Trustee, the Company shall execute any and all instruments for more
fully and certainly vesting in and confirming to such successor Trustee all such
rights, powers and trusts.

    No successor Trustee shall accept its appointment unless at the time of such
acceptance such successor Trustee shall be qualified and eligible under this
Article.

Section 6.12.  MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO BUSINESS.

    Any corporation into which the Trustee may be merged or converted or with
which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all the corporate trust business
of the Trustee, shall be the successor of the Trustee hereunder, provided such
corporation shall be otherwise qualified and eligible under this Article,
without the execution or filing of any paper or any further act on the part of
any of the parties hereto. In case any Securities shall have been authenticated,
but not delivered, by the Trustee then in office, any successor by merger,
conversion or consolidation to such authenticating Trustee may adopt such
authentication and deliver the Securities so authenticated with the same effect
as if such successor Trustee had itself authenticated such Securities.

Section 6.13.  PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY.

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

Section 6.14.  APPOINTMENT OF AUTHENTICATING AGENT.

    The Trustee may appoint an Authenticating Agent or Agents which shall be
authorized to act on behalf of the Trustee to authenticate Securities (including
Additional Securities) issued upon original issue and upon exchange,
registration of transfer or partial redemption or partial purchase or pursuant
to Section 3.08, and Securities so authenticated shall be entitled to the
benefits of this Indenture and shall be valid and obligatory for all purposes as
if authenticated by the Trustee hereunder. Wherever reference is made in this
Indenture to the authentication and delivery of Securities by the Trustee or the
Trustee's certificate of authentication, such reference shall be deemed to
include authentication and delivery on behalf of the Trustee by an
Authenticating Agent and a certificate of authentication executed on behalf of
the Trustee by an Authenticating Agent. Each Authenticating Agent shall be
acceptable to the Company and shall at all times be a corporation organized and
doing business under the laws of the United States of America, any State thereof
or the District of Columbia, authorized under such laws to act as Authenticating
Agent, having a combined capital and surplus of not less than $50,000,000 and
subject to supervision or examination by Federal or State authority. If such
Authenticating Agent publishes reports of condition at least annually, pursuant
to law or to the requirements of said supervising or examining authority, then
for the purposes of this Section, the combined capital and surplus of such
Authenticating Agent shall be deemed to be its combined capital and surplus as
set forth in its most recent report of condition so published. If at any time an
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, such Authenticating Agent shall resign immediately
in the manner and with the effect specified in this Section.

    Any corporation into which an Authenticating Agent may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which such Authenticating Agent
shall be a party, or any corporation succeeding to all or substantially all the
corporate agency or corporate trust business of an Authenticating Agent, shall
continue to be an Authenticating Agent, provided such corporation shall be
otherwise eligible under this Section, without the execution or filing of any
paper or any further act on the part of the Trustee or the Authenticating Agent.

                                       52
<PAGE>
    An Authenticating Agent may resign at any time by giving written notice
thereof to the Trustee and to the Company. The Trustee may at any time terminate
the agency of an Authenticating Agent by giving written notice thereof 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 such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, the Trustee may appoint a successor Authenticating
Agent which shall be acceptable to the Company and shall give notice of such
appointment in the manner provided in Section 1.06, to all Holders as their
names and addresses appear in the Security Register. Any successor
Authenticating Agent upon acceptance of its appointment hereunder shall become
vested with all the rights, powers and duties of its predecessor hereunder, with
like effect as if originally named as an Authenticating Agent. No successor
Authenticating Agent shall be appointed unless eligible under the provisions of
this Section.

    The Company agrees to pay to each Authenticating Agent from time to time
reasonable compensation for its services under this Section.

    If an appointment is made pursuant to this Section, the Securities may have
endorsed thereon, in addition to the Trustee's certificate of authentication, an
alternative certificate of authentication in the following form:

    This is one of the Securities described in the within-mentioned Indenture.

exchange and where notices and demands to or upon the Company in respect of the
Securities and this Indenture may be served. The Company will give prompt
written notice to the Trustee of the location, and any change in the location,
of such office or agency. If at any time the Company shall fail to maintain any
such required office or agency or shall fail to furnish the Trustee with the
address thereof, such presentations, surrenders, notices and demands may be made
or served at the Corporate Trust Office of the Trustee, and the Company hereby
appoints the Trustee as its agent to receive all such presentations, surrenders,

or agencies (in or outside the Borough of Manhattan, The City of New York) where
the Securities may be presented or surrendered for any or all such purposes and
may from time to time rescind such designations; PROVIDED, HOWEVER, that no such
designation or rescission shall in any manner relieve the Company of its
obligation to maintain an office or agency in the Borough of Manhattan, The City
of New York, for such purposes. The Company will give prompt written notice to
the Trustee of any such designation or rescission and of any change in the
location of any such other office or agency.

Section 10.03.  MONEY FOR SECURITY PAYMENTS TO BE HELD IN TRUST.

    If the Company shall at any time act as its own Paying Agent, it will, on or
before each due date of the principal of (and premium, if any) or interest on
any of the Securities, segregate and hold in trust for the benefit of the
Persons entitled thereto a sum sufficient to pay the principal (and premium, if
any) or interest so becoming due until such sums shall be paid to such Persons
or otherwise disposed of as herein provided and will promptly notify the Trustee
of its action or failure so to act.

    Whenever the Company shall have one or more Paying Agents, it will, prior to
each due date of the principal of (and premium, if any) or interest on any
Securities, deposit with a Paying Agent a sum sufficient to pay the principal
(and premium, if any) or interest so becoming due, such sum to be held as
provided by the Trust Indenture Act, and (unless such Paying Agent is the
Trustee) the Company will promptly notify the Trustee of its action or failure
so to act.

    The Company will cause each Paying Agent other than the Trustee to execute
and deliver to the Trustee an instrument in which such Paying Agent shall agree
with the Trustee, subject to the provisions of this Section, that such Paying
Agent will: (i) comply with the provisions of the Trust Indenture Act applicable
to it as Paying Agent and (ii) during the continuance of any default by the
Company (or any other obligor upon the Securities) in the making of any payment
in respect of the Securities, upon the written request of the Trustee, forthwith
pay to the Trustee all sums held in trust by such Paying Agent as such.

    The Company may at any time, for the purpose of obtaining the satisfaction
and discharge of this Indenture or for any other purpose, pay, or by Company
Order direct any Paying Agent to pay, to the

                                       58
<PAGE>
Trustee all sums held in trust by the Company or such Paying Agent, such sums to
be held by the Trustee upon the same trusts as those upon which such sums were
held by the Company or such Paying Agent; and, upon such payment by any Paying
Agent to the Trustee, such Paying Agent shall be released from all further
liability with respect to such money.

    Any money deposited with the Trustee or any Paying Agent, or then held by
the Company, in trust for the payment of the principal of (and premium, if any)
or interest on any Security and remaining unclaimed for two years after such
principal (and premium, if any) or interest has become due and payable shall be
paid to the Company on Company Request, or (if then held by the Company) shall
be discharged from such trust; and the Holder of such Security shall thereafter,
as an unsecured general creditor, look only to the Company for payment thereof,
and all liability of the Trustee or such Paying Agent with respect to such trust
money, and all liability of the Company as trustee thereof, shall thereupon
cease.

Section 10.04.  EXISTENCE.

    Subject to Article 8, the Company will do or cause to be done all things
necessary to preserve and keep in full force and effect its existence, rights
(charter and statutory) and material franchises; PROVIDED, HOWEVER, that the
Company shall not be required to preserve any such right or franchise if the
Board of Directors in good faith 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 10.05.  MAINTENANCE OF PROPERTIES.

    The Company will cause all material properties used or useful in the conduct
of its business or the business of any Restricted 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 material properties if
such discontinuance is, as determined by the Board of Directors in good faith,
desirable in the conduct of its business or the business of any Restricted
Subsidiary and not disadvantageous in any material respect to the Holders.

Section 10.06.  PAYMENT OF TAXES AND OTHER CLAIMS.

    The Company will pay or discharge or cause to be paid or discharged, before
the same shall become delinquent, (1) all taxes, assessments and governmental
charges levied or imposed upon the Company or any of its Restricted Subsidiaries
or upon the income, profits or property of the Company or any of its Restricted
Subsidiaries, and (2) all lawful claims for labor, materials and supplies which,
if unpaid, might by law become a lien upon the property of the Company or any of
its Restricted Subsidiaries; PROVIDED, HOWEVER, that the Company shall not be
required to pay or discharge or cause to be paid or discharged any such tax,
assessment, charge or claim whose amount, applicability or validity is being
contested in good faith by appropriate proceedings.

Section 10.07.  MAINTENANCE OF INSURANCE.

    The Company shall, and shall cause its Restricted Subsidiaries to, keep at
all times all of their properties which are of an insurable nature insured
against loss or damage with insurers believed by the Company to be responsible
to the extent that property of similar character is usually so insured by
corporations similarly situated and owning like properties in accordance with
good business practice.

       or investment banking firm of national standing and evidenced by a
       written opinion of such firm), received by the Company from the issuance
       and sale (other than to a Restricted Subsidiary) on or after
       February 24, 2000 of shares of its Capital Stock (other than Redeemable
       Stock), or any options, warrants or other rights to purchase such Capital
       Stock (other than Redeemable Stock), other than shares of Capital Stock
       or options, warrants or other rights to purchase Capital Stock (or shares
       issuable upon exercise thereof), the proceeds of the issuance of which is
       used to make a Directed Investment (unless such designation has been
       revoked by the Board of Directors and the Company is able to make such
       Investment pursuant to this Section 10.09 (other than as a Directed
       Investment)), plus

           (3)  the aggregate net proceeds, including the fair market value of
       property other than cash (as determined, (A) in the case of any property
       other than cash with a value less than $25.0 million, by the Board of
       Directors, whose good faith determination shall be conclusive and as
       evidenced by a Board Resolution, or (B) in the case of any property other
       than cash with a value equal to or greater than $25.0 million, by an
       accounting, appraisal or investment banking firm of national standing and
       evidenced by a written opinion of such firm), received by the Company
       from the issuance or sale (other than to a Restricted Subsidiary) after
       February 24, 2000 of any Capital Stock of the Company (other than

       such Capital Stock (other than Redeemable Stock), upon the conversion of,
       or exchange for, Debt of the Company or a Restricted Subsidiary.

    The foregoing limitations in this Section 10.09 do not limit or restrict the
making of any Permitted Distribution, Permitted Investment or Directed
Investment, and neither a Permitted Distribution nor a Permitted Investment
shall be counted as a Restricted Payment for purposes of clause (c) above. In
addition, the foregoing limitations do not prevent the Company from (I) paying a
dividend on Capital Stock of the Company within 60 days after the declaration
thereof if, on the date when the dividend was declared, the Company could have
paid such dividend in accordance with the provisions of this Indenture,
(II) repurchasing Capital Stock of the Company (including options, warrants or
other rights to acquire such Capital Stock) from former employees or Directors
of the Company or any Subsidiary thereof for consideration not to exceed (A) in
the case of all such employees or directors (other than Itemized Executives),
$500,000 in the aggregate in any fiscal year, with amounts not used in any given
fiscal year being carried over into subsequent fiscal years, and (B) in the case
of any Itemized Executive, $2.0 million per Itemized Executive (plus the amount
of any proceeds of any key man life insurance received by the Company in respect
of such Itemized Executive) in any fiscal year, with the aggregate amount of
such repurchases under this clause (II)(B) not to exceed $5.0 million in any
fiscal year; PROVIDED that the aggregate amount of all such repurchases made
pursuant to this clause (II) does not exceed $17.0 million in the aggregate (not
including the amount of any proceeds of key man life insurance received by the
Company in respect to any Itemized Executive), (III) the repurchase, redemption
or other acquisition for value of Capital Stock of the Company to the extent
necessary to prevent the loss or secure the renewal or reinstatement of any
license or franchise held by the Company or any of its Subsidiaries from any
governmental agency, (IV) making a loan in the aggregate principal amount of
approximately $2.2 million to certain officer(s) of the Company as described in
the Memorandum (with Restricted Payments pursuant to this clause not being
counted as Restricted Payments for purposes of clause (c) above), (V) the
redemption, repurchase, defeasance or other acquisition or retirement for value
of Indebtedness that is

                                       61
<PAGE>
subordinated in right of payment to the Securities, including premium, if any,
and accrued and unpaid interest, with the proceeds of, or in exchange for,
(a) the proceeds of a capital contribution or a substantially concurrent
offering of, shares of Capital Stock (other than Redeemable Stock) of the
Company (or options, warrants or other rights to acquire such Capital Stock) the
proceeds of which are not designated as a Directed Investment, or (b) Debt that
is at least as subordinated in right of payment to the Securities, including
premium, if any, and accrued and unpaid interest, as the Debt being purchased,
(with Restricted Payments pursuant to this clause not being counted as
Restricted Payments for purposes of clause (c) above), (VI) the repurchase,
redemption or other acquisition of Capital Stock of the Company (or options,
warrants or other rights to acquire such Capital Stock) in exchange for, or out
of the proceeds of a capital contribution or a substantially concurrent offering
of, shares of Common Stock (other than Redeemable Stock) of the Company (or
options, warrants or other rights to acquire such Capital Stock) the proceeds of
which are not designated as a Directed Investment or (VII) other Restricted
Payments not to exceed $5.0 million in the aggregate at any time outstanding
(with Restricted Payments pursuant to this clause not being counted as
Restricted Payments for purposes of clause (c) above).

    Notwithstanding the foregoing, no Investment in a Person that immediately
thereafter would be a Restricted Subsidiary will be a Restricted Payment. In
addition, if any Person in which an Investment is made, which Investment
constitutes a Restricted Payment when made, thereafter becomes a Restricted
Subsidiary, all such Investments previously made in such Person shall no longer
be counted as Restricted Payments for purposes of calculating the aggregate
amount of Restricted Payments pursuant to clause (c) of the third preceding
paragraph or the aggregate amount of Investments pursuant to clause (V)(a) of
the immediately preceding paragraph, in each case to the extent such Investments
would otherwise be so counted.

    For purposes of clause (c)(3) above, the net proceeds received by the
Company from the issuance or sale of its Capital Stock either upon the
conversion of, or exchange for, Debt of the Company or any Restricted Subsidiary
shall be deemed to be an amount equal to (a) the sum of (i) the principal amount
or accreted value (whichever is less) of such Debt on the date of such
conversion or exchange and (ii) the additional cash consideration, if any,
received by the Company upon such conversion or exchange, less any payment on
account of fractional shares, MINUS (b) all expenses incurred in connection with
such issuance or sale. In addition, for purposes of clause (c)(3) above, the net
proceeds received by the Company from the issuance or sale of its Capital Stock
upon the exercise of any options or warrants of the Company or any Restricted
Subsidiary shall be deemed to be an amount equal to (a) the additional cash
consideration, if any, received by the Company upon such exercise, MINUS
(b) all expenses incurred in connection with such issuance or sale.

    For purposes of this Section 10.09, if a particular Restricted Payment
involves a non-cash payment, including a distribution of assets, then such
Restricted Payment shall be deemed to be an amount equal to the cash portion of
such Restricted Payment, if any, plus an amount equal to the fair market value
of the non-cash portion of such Restricted Payment, as determined by the Board
of Directors (whose good faith determination shall be conclusive and evidenced
by a Board Resolution).

    The amount of any Investment outstanding at any time shall be deemed to be
equal to the amount of such Investment on the date made, less the return of
capital, repayment of loans and return on capital (including interest and
dividends), in each case, received in cash, up to the amount of such Investment
on the date made.

Section 10.10.  RESTRICTED SUBSIDIARIES.

    Subject to compliance with Section 10.09, the Board of Directors may
designate any Restricted Subsidiary as an Unrestricted Subsidiary.

    The designation by the Board of Directors of a Restricted Subsidiary as an
Unrestricted Subsidiary shall, for all purposes of Section 10.09 (including
clause (b) thereof), be deemed to be a Restricted

                                       62
<PAGE>
Payment of an amount equal to the fair market value of the Company's ownership
interest in such Subsidiary (including, without duplication, such indirect
ownership interest in all Subsidiaries of such Subsidiary), as determined by the
Board of Directors in good faith and evidenced by a Board Resolution.

    Notwithstanding the foregoing provisions of this Section 10.10, the Board of
Directors may not designate a Subsidiary of the Company to be an Unrestricted
Subsidiary if, after such designation, (a) the Company or any of its other
Restricted Subsidiaries (i) provides credit support for, or a Guarantee of, any
Debt of such Subsidiary (including any undertaking, agreement or instrument
evidencing such Debt) or (ii) is directly or indirectly liable for any Debt of
such Subsidiary, (b) a default with respect to any Debt of such Subsidiary
(including any right which the holders thereof may have to take enforcement
action against such Subsidiary) would permit (upon notice, lapse of time or
both) any holder of any other Debt of the Company or any Restricted Subsidiary
to declare a default on such other Debt or cause the payment thereof to be
accelerated or payable prior to its final scheduled maturity or (c) such
Subsidiary owns any Capital Stock of, or owns or holds any Lien on any property
of, any Restricted Subsidiary which is not a Subsidiary of the Subsidiary to be
so designated.

    The Board of Directors, from time to time, may designate any Person that is
about to become a Subsidiary of the Company as an Unrestricted Subsidiary, and
may designate any newly-created Subsidiary of the Company as an Unrestricted
Subsidiary, if at the time such Subsidiary is created it contains no assets
(other than such DE MINIMIS amount of assets then required by law for the
formation of corporations) and no Debt. Subsidiaries of the Company that are not
designated by the Board of Directors as Restricted or Unrestricted Subsidiaries
shall be deemed to be Restricted Subsidiaries. Notwithstanding any provisions of
this Section 10.10, all Subsidiaries of an Unrestricted Subsidiary shall be
Unrestricted Subsidiaries.

Section 10.11.  TRANSACTIONS WITH AFFILIATES.

    The Company shall not, and shall not permit any Restricted Subsidiary to,
directly or indirectly, enter into any transaction (including the purchase,
sale, lease or exchange of any property or the rendering of any service) or
series of related transactions with any Affiliate of the Company on terms that
are less favorable to the Company or such Restricted Subsidiary, as the case may
be, than those which might be obtained at the time of such transaction from a
Person that is not such an Affiliate; PROVIDED, HOWEVER, that this
Section 10.11 shall not limit, or be applicable to, (i) any transaction between
Unrestricted Subsidiaries not involving the Company or any Restricted
Subsidiary, (ii) any transaction between the Company and any Restricted
Subsidiary or between Restricted Subsidiaries or (iii) any Permitted
Transactions. In addition, any transaction or series of related transactions,
other than Permitted Transactions, between the Company or any Restricted
Subsidiary and any Affiliate of the Company (other than a Restricted Subsidiary)
involving an aggregate consideration of $5 million or more must be approved in
good faith by a majority of the Company's Disinterested Directors (of which
there must be at least one) and evidenced by a Board Resolution, or if there is
no Disinterested Director at such time or such transaction involves aggregate
consideration of $25.0 million or more, by an opinion as to fairness ("Fairness
Opinion") to the Company or such Subsidiary from a financial point of view
issued by an accounting, appraisal or investment banking firm of national
standing. For purposes of this Section 10.11, any transaction or series of
related transactions between the Company or any Restricted Subsidiary and an
Affiliate of the Company that is approved by a majority of the Disinterested
Directors (of which there must be at least one to utilize this method of
approval) and evidenced by a Board Resolution or for which a Fairness Opinion
has been issued shall be deemed to be on terms as favorable as those that might
be obtained at the time of such transaction (or series of transactions) from a
Person that is not such an Affiliate and thus shall be permitted under this
Section 10.11.

Section 10.12.  LIENS.

    The Company shall not and shall not permit any of its Restricted
Subsidiaries to create, incur, assume or otherwise cause or suffer to exist or
become effective any Lien of any kind (other than Permitted Liens)

                                       63
<PAGE>
upon any of their property or assets, now owned or hereafter acquired, unless
all payments due under this Indenture and the Securities are secured on an equal
and ratable basis with the obligations so secured until such time as such
obligations are no longer secured by a Lien.

Section 10.13.  CHANGE OF CONTROL.

    Upon the occurrence of a Change of Control, the Company shall be required to
make an Offer to Purchase all or any part of Outstanding Securities at a cash
purchase price equal to 101% of the aggregate principal amount thereof, plus
accrued and unpaid interest and Liquidated Damages, if any, to the Purchase
Date. The Offer to Purchase must be made within 30 days following a Change of
Control, must remain open for at least 30 and not more than 180 days and must
comply with the requirements of Rule 14e-1 under the Exchange Act and any other
applicable securities laws and regulations.

Section 10.14.  DIVIDEND AND OTHER PAYMENT RESTRICTIONS AFFECTING SUBSIDIARIES.

    The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, directly or indirectly, create or otherwise cause or suffer to
exist or become effective any encumbrance or restriction on the ability of any
Restricted Subsidiary to (i)(a) pay dividends or make any other distributions to
the Company or any of its Restricted Subsidiaries (1) on its Capital Stock or
(2) with respect to any other interest or participation in, or measured by, its
profits, or (b) pay any indebtedness owed to the Company or any of its
Restricted Subsidiaries, (ii) make loans or advances to the Company or any of
its Restricted Subsidiaries or (iii) transfer any of its properties or assets to
the Company or any of its Restricted Subsidiaries. However, the foregoing
restrictions will not apply to encumbrances or restrictions existing under or by
reason of (a) existing Debt as in effect on the date hereof, (b) any Credit
Facility as in effect as of the date hereof (or in the case of the New Credit
Facility, as initially executed by the parties thereto), and any amendments,
modifications, restatements, renewals, increases, supplements, refundings,
replacements or refinancings thereof, provided that such amendments,
modifications, restatements, renewals, increases, supplements, refundings,
replacements or refinancings are no more restrictive, taken as a whole, with
respect to such dividend and other payment restrictions than those contained in
such Credit Facility as in effect on the date hereof (as conclusively determined
in good faith by the Board of Directors and set forth in a Board Resolution),
(c) this Indenture and the Securities, (d) applicable law, (e) any instrument
governing Debt (and any amendments, modifications, restatements, renewals,
increases, supplements, refundings, replacements or refinancings thereof,
provided that such amendments, modifications, restatements, renewals, increases,
supplements, refundings, replacement or refinancings are no more restrictive,
taken as a whole, with respect to such dividend and other payment restrictions
than those contained in such Debt as in effect on the date of its incurrence by
the Company or any Restricted Subsidiary (as conclusively determined in good
faith by an executive officer of the Company)) or Capital Stock of a Person
acquired by the Company or any of its Restricted Subsidiaries as in effect at
the time of such acquisition (except to the extent such Debt was incurred in
connection with or in contemplation of such acquisition), which encumbrance or
restriction is not applicable to any Person, or the properties or assets of any
Person, other than the Person, or the property or assets of the Person, so
acquired, provided that, in the case of Debt, such Debt was permitted by the
terms of this Indenture to be incurred, (f) customary non-assignment provisions
in leases entered into in the ordinary course of business, (g) purchase money
obligations for property acquired in the ordinary course of business that impose
restrictions of the nature described in clause (iii) above on the property so
acquired, (h) any agreement for the sale or other disposition of a Restricted
Subsidiary that restricts distributions by that Subsidiary pending its sale or
other disposition, (i) Liens securing Debt otherwise permitted to be incurred
pursuant to the provisions of the covenant described above under Section 10.12
that limit the right of the Company or any of its Restricted Subsidiaries to
dispose of the assets subject to such Lien, (j) provisions with respect to the
disposition or distribution of assets or property in joint venture agreements
and other similar agreements entered into in the ordinary course of business and
(k) restrictions on cash or other deposits or net worth imposed by customers
under contracts entered into in the ordinary course of business.

Section 10.15.  ACTIVITIES OF THE COMPANY AND RESTRICTED SUBSIDIARIES.

    The Company shall not, and shall not permit any Restricted Subsidiary to,
engage in any business other than the telecommunications business and related
activities and services, including such businesses, activities and services as
the Company and the Restricted Subsidiaries are engaged in on the Closing Date.

Section 10.16.  PROVISION OF FINANCIAL INFORMATION.

    Whether or not the Company is subject to Section 13(a) or 15(d) of the
Exchange Act, or any successor provision thereto, the Company shall file with
the Commission the annual reports, quarterly reports and other documents which
the Company would have been required to file with the Commission pursuant to
such Section 13(a) or 15(d) or any successor provision thereto if the Company
were subject thereto, such documents to be filed with the Commission on or prior
to the respective dates (the "Required Filing Dates") by which the Company would
have been required to file them. The Company shall also in any event (a) within
15 days of each Required Filing Date (i) transmit by mail to all Holders, as
their names and addresses appear in the Security Register, without cost to such
Holders, and (ii) file with the Trustee copies of the annual reports, quarterly
reports and other documents which the Company would have been required to file
with the Commission pursuant to Section 13(a) or 15(d) of the Exchange Act or
any successor provisions thereto if the Company were subject thereto and (b) if
filing such documents by the Company with the Commission is not permitted under
the Exchange Act, promptly upon written request supply copies of such documents
to any prospective Holder. The Trustee's receipt of such reports, information
and documents shall not constitute constructive notice of any information
contained therein or determinable from information contained therein.

    In addition, for so long as any Securities remain outstanding, the Company
shall furnish to the Holders and to securities analysts and prospective
investors, upon their request, the information required to be delivered pursuant
to Rule 144A under the Securities Act.

Section 10.17.  STATEMENT BY OFFICERS AS TO DEFAULT: COMPLIANCE CERTIFICATES.

    (a)  The Company shall deliver to the Trustee, within 120 days after the end
of each fiscal year of the Company ending after the date hereof an Officers'
Certificate, stating whether or not to the best knowledge of the signers 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 status thereof of
which they may have knowledge.

    (b)  The Company shall deliver to a Responsible Officer of the Trustee, as
soon as possible and in any event within 10 days after the Company becomes aware

setting forth the details of such Default or Event of Default, and the action
which the Company proposes to take with respect thereto.

Section 10.18.  WAIVER OF CERTAIN COVENANTS.

    The Company may omit in any particular instance to comply with any covenant
or condition set forth in Section 8.01, provided pursuant to Section 9.01(2) and
set forth in Sections 10.04 to 10.16, inclusive, if before the time for such
compliance the Holders of at least a majority in principal amount at Stated
Maturity of the Outstanding Securities shall, by Act of such Holders, either
waive such compliance in such instance or generally waive compliance with such
covenant or condition, but no such waiver shall extend to or affect such
covenant or condition 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 any such covenant or condition shall remain in full
force and effect; PROVIDED, HOWEVER, with respect to an Offer to Purchase as to
which an Offer has been mailed, no such waiver may be made or shall be effective
against

                                       65
<PAGE>
any Holder tendering Securities pursuant to such Offer, and the Company may not
omit to comply with the terms of such Offer as to such Holder.

Section 10.19.  LIMITATION ON ISSUANCES AND SALES OF EQUITY INTERESTS IN WHOLLY
  OWNED SUBSIDIARIES.

    The Company (i) shall not, and shall not permit any Restricted Subsidiary of
the Company to, transfer, convey, sell or otherwise dispose ("Transfer") of any
Capital Stock in any Wholly Owned Restricted Subsidiary of the Company to any
Person (other than the Company or a Wholly Owned Restricted Subsidiary of the
Company) unless (a) such Transfer is of all the Capital Stock in such Wholly
Owned Restricted Subsidiary and (b) the cash Net Proceeds from such Transfer are
applied in accordance with the covenant described below under Section 10.21 and
(ii) will not permit any Wholly Owned Restricted Subsidiary of the Company to
issue any of its Capital Stock (other than, if necessary, shares of its Capital
Stock constituting directors' qualifying shares) to any Person other than to the
Company or a Wholly Owned Restricted Subsidiary of the Company. The foregoing
restrictions shall not apply to (i) the creation of Permitted Joint Ventures;
(ii) any Transfer required by applicable law or regulation, (iii) the issuance
of Redeemable Stock that is otherwise permitted to be issued pursuant to the
terms of this Indenture, and (iv) Transfers in which the Company or a Restricted
Subsidiary acquired at the same time not less than its proportionate share in
such issuance of Capital Stock.

Section 10.20.  PAYMENTS FOR CONSENT.

    Neither the Company nor any of its Restricted Subsidiaries shall, directly
or indirectly, pay or cause to be paid any consideration, whether by way of
interest, fee or otherwise, to any Holder of any Securities for or as an
inducement to any consent, waiver or amendment of any of the terms or provisions
of this Indenture or the Securities unless such consideration is offered to be
paid or is paid to all Holders of the Securities that consent, waive or agree to
amend in the time frame set forth in the solicitation documents relating to such
consent, waiver or agreement.

Section 10.21.  ASSET SALES.

    The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, consummate an Asset Sale unless (i) the Company (or the
Restricted Subsidiary, as the case may be) receives consideration at the time of
such Asset Sale at least equal to the fair market value (which shall be
conclusively evidenced by a resolution of the Board of Directors set forth in an
Officers' Certificate delivered to the Trustee) of the assets or Capital Stock
issued or sold or otherwise disposed of and (ii) at least 80% of the
consideration therefor received by the Company or such Subsidiary is in the form
of cash; provided that the amount of (x) any liabilities (as shown on the
Company's or such Restricted Subsidiary's most recent balance sheet), of the
Company or any Restricted Subsidiary (other than contingent liabilities and
liabilities that are by their terms subordinated to the Securities or any
guarantee thereof) that are assumed by the transferee of any such assets and
(y) any securities, notes or other obligations received by the Company or any
such Restricted Subsidiary from such transferee that are contemporaneously
(subject to ordinary settlement periods) converted by the Company or such
Subsidiary into cash (to the extent of the cash received), shall be deemed to be
cash for purposes of this provision.

    Within 360 days after the receipt of any Net Proceeds from an Asset Sale,
the Company may apply such Net Proceeds, at its option, (a) to repay Debt under
a Credit Facility or any Vendor Financing Debt or (b) to make a capital
expenditure in the same or similar line of business as the Company is engaged in
on the date hereof or in a business reasonably related thereto, or (c) to
acquire (i) Capital Stock of an entity that is or becomes a Restricted
Subsidiary or (ii) other long-term assets that are used or useful in the same or
similar line of business as the Company or such Restricted Subsidiaries were
engaged in on the date hereof or in businesses reasonably related thereto.
Pending the final application of any such Net Proceeds, the Company may
temporarily reduce revolving credit borrowings or otherwise invest such Net
Proceeds in any manner that is not prohibited by this Indenture. Any Net
Proceeds from Asset Sales that are not

                                       66
<PAGE>
applied or invested as provided in the first sentence of this paragraph will be
deemed to constitute "Excess Proceeds." When the aggregate amount of Excess
Proceeds exceeds $5.0 million, the Company will be required to make an offer (an
"Asset Sale Offer") to all Holders of Securities and all holders of other Debt
that is PARI PASSU with the Securities containing provisions similar to those
set forth in this Indenture with respect to offers to purchase or redeem with
the proceeds of sales of assets to purchase the maximum principal amount at
maturity of Securities and such other PARI PASSU Debt that may be purchased out
of the Excess Proceeds. The offer price for such Asset Sale Offer shall be an
amount in cash equal to 100% of the principal amount thereof plus accrued and
unpaid interest thereon, if any, to the date of purchase, in accordance with the
procedures set forth in this Indenture and the instrument or instruments
governing such other PARI PASSU Debt, respectively. To the extent that any
Excess Proceeds remain after consummation of an Asset Sale Offer, the Company
may use such Excess Proceeds for any purpose not otherwise prohibited by this
Indenture. If the aggregate principal amount of Securities tendered into such
Asset Sale Offer surrendered by Holders thereof exceeds the amount of Excess
Proceeds, the Trustee shall select the Securities to be purchased on a pro rata
basis. Upon completion of such offer to purchase, the amount of Excess Proceeds
shall be reset at zero.

Redeemable Stock), the Company may redeem up to 35% of the aggregate principal
amount of the Securities originally issued with the proceeds of such sale at a
Redemption Price equal to 111% of such principal amount on the Redemption Date,

    In the case of any partial redemption, selection of the Securities for
redemption will be made by the Trustee in compliance with the requirements of
the principal national securities exchange, if any, on which the Securities are
listed or, if the Securities are not listed on a national securities exchange,
on a PRO RATA basis, by lot or by such other method as the Trustee shall deem to
be fair and appropriate; PROVIDED that no Security of $1,000 in principal amount
or less shall be redeemed in part.

    The Trustee shall promptly notify the Company and each Security Registrar in
writing of the Securities selected for redemption and, in the case of any
Securities selected for partial redemption, the principal amount thereof to be
redeemed.

    For all purposes of this Indenture and of the Securities, unless the context
otherwise requires, all provisions relating to the redemption of Securities
shall relate, in the case of any Securities redeemed or to be redeemed only in
part, to the portion of the principal amount of such Securities which has been
or is to be redeemed.

Section 11.05.  NOTICE OF REDEMPTION.

    Notice of redemption shall be given by first-class mail, postage prepaid,
mailed not less than 30 nor more than 45 days prior to the Redemption Date, to
each Holder of Securities to be redeemed, at his address appearing in the
Security Register.

    All notices of redemption shall state (including CUSIP, CINS and ISIN
numbers, if any):

        (1)  the Redemption Date,

        (2)  the Redemption Price,

        (3)  if less than all the Outstanding Securities are to be redeemed, the
    identification (and, in the case of partial redemption, the principal
    amounts) of the particular Securities to be redeemed, including CUSIP, CINS
    and ISIN numbers,

        (4)  that on the Redemption Date the Redemption Price will become due
    and payable upon each such Security to be redeemed and that cash interest
    thereon will cease to accrue on and after said Redemption Date,

        (5)  the place or places where such Securities are to be surrendered for
    payment of the Redemption Price, and

        (6)  if the redemption is being made pursuant to the provisions of the
    Securities set forth in the third paragraph of Section 2.03, a brief
    description of the nature and amount of Capital Stock sold by the Company,
    the aggregate purchase price thereof and the net cash proceeds therefrom
    available for such redemption, the date or dates on which such sale was
    completed and the percentage of the aggregate principal amount of
    Outstanding Securities being redeemed.

    Notice of redemption of Securities to be redeemed at the election of the
Company shall be given by the Company or, at the Company's request, by the
Trustee in the name and at the expense of the Company and shall be irrevocable.

Section 11.06.  DEPOSIT OF REDEMPTION PRICE.

    On or before 10:00 a.m. New York time on any Redemption Date, the Company
shall deposit with the Trustee or with a Paying Agent (or, if the Company is
acting as its own Paying Agent, segregate and hold in trust as provided in
Section 10.03) an amount of money sufficient to pay the Redemption Price of, and
(except if the Redemption Date shall be an Interest Payment Date) any applicable
accrued interest on, all the Securities which are to be redeemed on that date.

Section 11.07.  SECURITIES PAYABLE ON REDEMPTION DATE.

    Notice of redemption having been given as aforesaid, the Securities so to be
redeemed shall, on the Redemption Date, become due and payable at the Redemption
Price therein specified, and from and after such date (unless the Company shall
default in the payment of the Redemption Price and any applicable accrued
interest) such Securities shall not bear interest. Upon surrender of any such
Security for redemption in accordance with said notice, such Security shall be
paid by the Company at the Redemption Price, together with any applicable
accrued and unpaid interest to the Redemption Date; PROVIDED, HOWEVER, that
installments of interest whose Stated Maturity is on or prior to the Redemption
Date shall be payable to the Holders of such Securities, or one or more
Predecessor Securities, registered as such at the close of business on the
relevant Record Dates according to their terms and the provisions of
Section 3.09.

    If any Security called for redemption in accordance with the election of the
Company made pursuant to Section 11.01 shall not be so paid upon surrender
thereof for redemption, the principal (and premium, if any) shall, until paid,
bear interest from the Redemption Date at the rate provided by the Security.

Section 11.08.  SECURITIES REDEEMED IN PART.

    Any Security which is to be redeemed only in part shall be surrendered at an
office or agency of the Company designated for that purpose pursuant to
Section 10.02 (with, if the Company or the Trustee so requires, due endorsement
by, or a written instrument of transfer in form satisfactory to the Company and
the Trustee duly executed by, the Holder thereof or his attorney duly authorized
in writing), and the Company shall execute, and the Trustee shall authenticate
and deliver to the Holder of such Security without service charge, a new
Security or Securities, of any authorized denomination as requested by such
Holder, in aggregate principal amount at Stated Maturity equal to and in
exchange for the unredeemed portion of the principal amount at Stated Maturity
of the Security so surrendered.

                       DEFEASANCE AND COVENANT DEFEASANCE

Section 12.01.  COMPANY'S OPTION TO EFFECT DEFEASANCE OR COVENANT DEFEASANCE.

    The Company may elect, at its option at any time, to have Section 12.02 or
Section 12.03 applied to the Outstanding Securities (as a whole and not in part)
upon compliance with the conditions set forth below in this Article. Any such
election shall be evidenced by a Board Resolution.

Section 12.02.  DEFEASANCE AND DISCHARGE.

    Upon the Company's exercise of its option to have this Section applied to
the Outstanding Securities (as a whole and not in part), the Company shall be
deemed to have been discharged from its obligations with respect to such
Securities as provided in this Section on and after the date the conditions set
forth in Section 12.04 are satisfied (hereinafter called "Defeasance"), and
thereafter such Securities shall not be subject to redemption pursuant thereto.
For this purpose, such Defeasance means that the Company shall be deemed to have
paid and discharged the entire indebtedness represented by such Securities and
to have satisfied all its other obligations under such Securities and this
Indenture insofar as such Securities are

                                       69
<PAGE>
concerned (and the Trustee, at the expense of the Company, shall execute proper
instruments acknowledging the same), subject to the following which shall
survive until otherwise terminated or discharged hereunder: (1) the rights of
Holders of such Securities to receive, solely from the trust fund described in
Section 12.04 and as more fully set forth in such Section, payments in respect
of the principal of and any premium and interest on such Securities when
payments are due, (2) the Company's obligations with respect to such Securities
under Sections 3.04, 3.05, 3.08, 10.02 and 10.03, (3) the rights, powers,
trusts, duties and immunities of the Trustee hereunder and (4) this Article.
Subject to compliance with this Article, the Company may exercise its option to
have this Section applied to the Outstanding Securities (as a whole and not in
part) notwithstanding the prior exercise of its option to have Section 12.03
applied to such Securities.

Section 12.03.  COVENANT DEFEASANCE.

    Upon the Company's exercise of its option to have this Section applied to
the Outstanding Securities (as a whole and not in part), (1) the Company shall
be released from its obligations under Section 8.01(iii), Sections 10.05 through
10.16, inclusive, and 10.19 through 10.21, inclusive and any covenant provided
pursuant to Section 9.01(2) and (2) the occurrence of any event specified in
Section 5.01(4) (with respect to Section 8.01(iii)), Section 5.01(5) (with
respect to any of Sections 10.05 through 10.16, inclusive and 10.19 through
10.21, inclusive, and any such covenants provided pursuant to Section 9.01(2)),
Section 5.01(6) or Section 5.01(7) shall be deemed not to be or result in an
Event of Default, in each case with respect to such Securities as provided in
this Section on and after the date the conditions set forth in Section 12.04 are
satisfied (hereinafter called "Covenant Defeasance"). For this purpose, such
Covenant Defeasance means that, with respect to such Securities, the Company may
omit to comply with and shall have no liability in respect of any term,
condition or limitation set forth in any such specified Section (to the extent
so specified in the case of Sections 5.01(4) and 5.01(5)), whether directly or
indirectly by reason of any reference elsewhere herein to any such Section or by
reason of any reference in any such Section to any other provision herein or in
any other document, but the remainder of this Indenture and such Securities
shall be unaffected thereby.

Section 12.04.  CONDITIONS TO DEFEASANCE OR COVENANT DEFEASANCE.

    The following shall be the conditions to the application of Section 12.02 or
Section 12.03 to the Outstanding Securities:

        (1)  The Company shall irrevocably have deposited or caused to be
    deposited with the Trustee (or another trustee which satisfies the
    requirements contemplated by Section 6.09 and agrees to comply with the
    provisions of this Article applicable to it) as trust funds in trust for the
    purpose of making the following payments, specifically pledged as security
    for, and dedicated solely to, the benefits of the Holders of such
    Securities, (A) money in an amount, or (B) U.S. Government Obligations which
    through the scheduled payment of principal and interest in respect thereof
    in accordance with their terms will provide, not later than one day before
    the due date of any payment, money in an amount, or (C) a combination
    thereof, in each case sufficient, in the opinion of a nationally recognized
    firm of independent public accountants expressed in a written certification
    thereof delivered to the Trustee, to pay and discharge, and which shall be
    applied by the Trustee (or any such other qualifying trustee) to pay and
    discharge, the principal of and any installment of interest on such
    Securities on the respective Stated Maturities thereof, in accordance with
    the terms of this Indenture and such Securities. As used herein, "U.S.
    Government Obligation" means (x) any security which is (i) a direct
    obligation of the United States of America for the payment of which the full
    faith and credit of the United States of America is pledged or (ii) an
    obligation of a Person controlled or supervised by and acting as an agency
    or instrumentality of the United States of America the payment of which is
    unconditionally guaranteed as a full faith and credit obligation by the
    United States of America, which, in either case (i) or (ii), is not callable
    or redeemable at the option of the issuer

                                       70
<PAGE>
    thereof, and (y) any depository receipt issued by a bank (as defined in
    Section 3(a)(2) of the Securities Act) as custodian with respect to any U.S.
    Government Obligation which is specified in Clause (x) above and held by
    such bank for the account of the holder of such depository receipt, or with
    respect to any specific payment of principal of or interest on any U.S.
    Government Obligation which is so specified and held, PROVIDED that (except
    as required by law) such custodian is not authorized to make any deduction
    from the amount payable to the holder of such depository receipt from any
    amount received by the custodian in respect of the U.S. Government
    Obligation or the specific payment of principal or interest evidenced by
    such depository receipt.

        (2)  In the event of an election to have Section 12.02 apply to the
    Outstanding Securities, the Company shall have delivered to the Trustee an
    Opinion of Counsel stating that (A) the Company has received from, or there
    has been published by, the Internal Revenue Service a ruling or (B) since
    the Closing Date there has been a change in the applicable Federal income
    tax law, in either case (A) or (B) to the effect that, and based thereon
    such opinion shall confirm that, the Holders of such Securities will not
    recognize gain or loss for Federal income tax purposes as a result of the
    deposit, Defeasance and discharge to be effected with respect to such
    Securities and will be subject to Federal income tax on the same amount, in
    the same manner and at the same times as would be the case if such deposit,
    Defeasance and discharge were not to occur.

        (3)  In the event of an election to have Section 12.03 apply to the
    Outstanding Securities, the Company shall have delivered to the Trustee an
    Opinion of Counsel to the effect that the Holders of such Securities will
    not recognize gain or loss for Federal income tax purposes as a result of
    the deposit and Covenant Defeasance to be effected with respect to such
    Securities and will be subject to Federal income tax on the same amount, in
    the same manner and at the same times as would be the case if such deposit
    and Covenant Defeasance were not to occur.

        (4)  No Default with respect to the Outstanding Securities shall have
    occurred and be continuing at the time of such deposit or, with regard to
    any such event specified in Sections 5.01(8) and (9), at any time on or
    prior to the 90th day after the date of such deposit (it being understood
    that this condition shall not be deemed satisfied until after such 90th
    day).

        (5)  Such Defeasance or Covenant Defeasance shall not cause the Trustee
    to have a conflicting interest within the meaning of the Trust Indenture Act
    (assuming all Securities are in default within the meaning of such Act).

        (6)  Such Defeasance or Covenant Defeasance shall not result in a breach
    or violation of, or constitute a default under, any other agreement or
    instrument to which the Company is a party or by which it is bound.

        (7)  Such Defeasance or Covenant Defeasance shall not result in the
    trust arising from such deposit constituting an investment company within
    the meaning of the Investment Company Act unless such trust shall be
    registered under such Act or exempt from registration thereunder.

        (8)  The Company shall have delivered to the Trustee an Officers'
    Certificate and an Opinion of Counsel, each stating that all conditions
    precedent with respect to such Defeasance or Covenant Defeasance have been
    complied with.

Section 12.05.  DEPOSITED MONEY AND U.S. GOVERNMENT OBLIGATIONS TO BE HELD IN
                TRUST; MISCELLANEOUS PROVISIONS.

    Subject to the provisions of the last paragraph of Section 10.03, all money
and U.S. Government Obligations (including the proceeds thereof) deposited with
the Trustee or other qualifying trustee (solely for purposes of this Section and
Section 12.06, the Trustee and any such other trustee are referred to
collectively as the "Trustee") pursuant to Section 12.04 in respect of the
Outstanding Securities shall be held in trust and applied by the Trustee, in
accordance with the provisions of such Securities and this

                                       71
<PAGE>
Indenture, to the payment, either directly or through any such Paying Agent
(including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Holders of such Securities, of all sums due and to become due
thereon in respect of principal and any premium and interest, but money so held
in trust need not be segregated from other funds except to the extent required
by law.

    The Company shall pay and indemnify the Trustee against any tax, fee or
other charge imposed on or assessed against the U.S. Government Obligations
deposited pursuant to Section 12.04 or the principal and interest received in
respect thereof other than any such tax, fee or other charge which by law is for
the account of the Holders of Outstanding Securities.

    Anything in this Article to the contrary notwithstanding, the Trustee shall
deliver or pay to the Company from time to time upon Company Request any money
or U.S. Government Obligations held by it as provided in Section 12.04 which, in
the opinion of a nationally recognized firm of independent public accountants
expressed in a written certification thereof delivered to the Trustee, are in
excess of the amount thereof which would then be required to be deposited to
effect the Defeasance or Covenant Defeasance, as the case may be, with respect
to the Outstanding Securities.

Section 12.06.  REINSTATEMENT.

    If the Trustee or the Paying Agent is unable to apply any money in
accordance with this Article with respect to any Securities by reason of any
order or judgment of any court or governmental authority enjoining, restraining
or otherwise prohibiting such application, then the obligations under this
Indenture and such Securities from which the Company has been discharged or
released pursuant to Section 12.02 or 12.03 shall be revived and reinstated as
though no deposit had occurred pursuant to this Article with respect to such
Securities, until such time as the Trustee or Paying Agent is permitted to apply
all money held in trust pursuant to Section 12.05 with respect to such
Securities in accordance with this Article; PROVIDED, HOWEVER, that if the
Company makes any payment of principal of or any premium or interest on any such
Security following such reinstatement of its obligations, the Company shall be
subrogated to the rights (if any) of the Holders of such Securities to receive
such payment from the money so held in trust.

                            ------------------------

    This instrument may be executed in any number of counterparts, each of which
so executed shall be deemed to be an original, but all such counterparts shall

executed, all as of the day and year first above written.

    Re: Nextel Partners, Inc. (the "Company")
       11% Senior Notes due 2010 (the "Notes")

Dear Sirs:

    In connection with our proposed purchase of U.S. $            aggregate
principal amount at stated maturity of the Notes, we confirm that:

    1. We understand that any subsequent transfer of the Notes is subject to
certain restrictions and conditions set forth in the Indenture dated as of
July 27, 2000 (the "Indenture"), relating to the Notes, and we agree to be bound
by, and not to resell, pledge or otherwise transfer the Notes except in
compliance with, such restrictions and conditions and the Securities Act of
1933, as amended (the "Securities Act").

    2. We understand that the offer and sale of the Notes have not been
registered under the Securities Act, and that the Notes may not be offered or
sold 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 offer or sell any Notes, we will do so only (A) to the Company
or any subsidiary thereof, (B) in accordance with Rule 144A under the Securities
Act to a "qualified institutional buyer" (as defined therein), (C) to an
institutional "accredited investor" (as defined below) that, prior to such
transfer, furnishes (or has furnished on its behalf by a U.S. broker-dealer) to
you and to the Company a signed letter substantially in the form of this letter,
(D) pursuant to the exemption from registration provided by Rule 144 under the
Securities Act, (E) pursuant to an effective registration statement under the
Securities Act, or (F) outside the United States in accordance with Rule 904 of
Regulation S 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
resales of the Notes are restricted as stated herein.

    3. We understand that, on any proposed resale of any Notes, we will be
required to furnish to you and the Company such certifications, legal opinions
and other information as you and the Company 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 under the Securities Act) and
have such knowledge and 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 its investment.

                                      A-2
<PAGE>
    5. We are acquiring the Notes purchased by us for our own 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 and the Company 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 proceedings or official inquiry with
respect to the matters covered hereby.

                                          Very truly yours,
