the equal and proportionate benefit of all Holders of the Securities, as
follows:

                                   ARTICLE 1.

                        Definitions and Other Provisions
                             of General Application

Section 1.01. DEFINITIONS.

                  For all purposes of this Indenture, except as otherwise
expressly provided or unless the context otherwise requires:

                  (1) the terms defined in this Article have the meanings
         assigned to them in this Article and include the plural as well as the
         singular;

                  (2) all other terms used herein which are defined in the Trust
         Indenture Act, either directly or by reference therein, have the
         meanings assigned to them therein;

                  (3) whenever this Indenture requires that a particular ratio
         or amount be calculated with respect to a specified period after giving
         effect to certain transactions or events on a PRO FORMA basis, such
         calculation will be made as if the transactions or events occurred on
         the first day of such period, unless otherwise specified herein, and
         all accounting terms not otherwise defined herein have the meanings
         assigned to them in accordance with generally accepted accounting
         principles (whether or not such is indicated herein), and, except as
         otherwise herein expressly provided, the term "generally accepted
         accounting principles" with respect to any computation required or
         permitted

<PAGE>

         hereunder shall mean such accounting principles as are generally
         accepted at the date of such computation;

                  (4) unless the context otherwise requires, any reference to an
         "Article" or a "Section" refers to an Article or Section, as the case
         may be, of this Indenture;

                  (5) the words "herein", "hereof' and "hereunder" and other
         words of similar import refer to this Indenture as a whole and not to
         any particular Article, Section or other subdivision; and

                  (6) each reference herein to a rule or form of the Commission
         shall mean such rule or form and any rule or form successor thereto, in

                  Certain terms, used principally in Article 6, are defined in
         that Article.

                  Whenever this Indenture requires that a particular ratio or
amount be calculated with respect to a specified period after giving effect to
certain transactions or events on a PRO FORMA basis, such calculation shall be
made as if the transactions or events occurred on the first day of such period,
unless otherwise specified.

individual signing such instrument or writing acknowledged to him the
execution thereof. Where such execution is by a signer acting in a capacity
other than his individual capacity, such certificate or affidavit shall also

executing the same, may also be proved in any other manner which the Trustee
deems sufficient.

                  The ownership of Securities shall be proved by the Security
Register.

                  Any request, demand, authorization, direction, notice,
consent, waiver or other Act of the Holder of any Security shall bind every
future Holder of the same Security and the Holder of every Security issued
upon the registration of transfer thereof or in exchange therefor or in lieu
thereof in respect of anything done, omitted or suffered to be done by the
Trustee or the Company in reliance thereon, whether or not notation of such
action is made upon such Security.

                  The Company may set any day as a record date for the
purpose of determining the Holders of Outstanding Securities entitled to give
or take any request, demand, authorization, direction, notice, consent,
waiver or other action provided or permitted by this Indenture to be given or
taken by Holders of Securities, PROVIDED that the Company may not set a
record date for,

                                      28
<PAGE>

and the 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 unless it is also Outstanding on
the date such action is to become effective. 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 with no 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
Company at its own expense, shall cause notice of such record date, the
proposed action by Holders and the applicable Record Expiration Date to be
given to the Trustee in writing and to each Holder of Securities in the
manner set forth in Section 1.06.

                  The Trustee may set any day as a record date for the
purpose of determining 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

                                      29
<PAGE>

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 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.

                                      30

<PAGE>

                  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.

impaired thereby.

                  In any case where any Interest Payment Date, Redemption Date,

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

                                       31

existing under the laws of the State of Delaware (herein called the

hereinafter referred to), for value received, hereby promises to pay to
_________, or registered assigns, the principal amount of _________ Dollars

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

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

(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

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.

                  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 Notes 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 Notes originally issued
remain outstanding immediately after the occurrence of any such redemption
(excluding Notes 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.

                  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

                                       36
<PAGE>

(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.

expressly provided in the Indenture with respect to matters requiring the
consent of each holder of Securities affected thereby, the consent of holders of
not less than a majority in aggregate principal amount at Stated Maturity of the
Securities.

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 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.

pursuant to Section 10.13.

              The Securities shall be known and designated as the "Senior

and they shall bear cash interest at the rate of 11% per annum, from
September 15, 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.

by the Company for such purpose; PROVIDED, HOWEVER, that at the option of the

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

              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 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

                                      44
<PAGE>

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.

              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

                                      45
<PAGE>

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

                                      46
<PAGE>

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

                  (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

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 3.07. SPECIAL TRANSFER PROVISIONS.

                  Unless and until a Security is exchanged for an Exchange
Security or sold in connection with an effective Shelf Registration Statement
pursuant to the Registration Rights Agreement, the following provisions shall
apply:

                  (a)   TRANSFERS TO QIBS. The following provisions shall apply
with respect to the registration of any proposed transfer of a Physical Security
or an interest in the Global Security prior to the removal of the Private
Placement Legend to a QIB (excluding Non-U.S. Persons):

                  (i)   If the Security to be transferred consists of (x) (A)
         U.S. Physical Securities or (B) an interest in an Offshore Global
         Security prior to the removal of the Private Placement Legend, the
         Security Registrar shall register the transfer if such transfer is
         being made by a proposed transferor who has checked the box provided
         for on the form of security 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 Rule 144A, to a transferee
         who has signed the certification provided for on the form of Security
         stating, or has otherwise advised the Company and the Security
         Registrar in writing, that it is purchasing the Security for its own
         account or an account with respect to which it exercises sole
         investment discretion and that it and any such account is a QIB within
         the meaning of Rule 144A, and is aware that the sale to it is being
         made in reliance on Rule 144A and acknowledges that it has received
         such information regarding the Company as it has requested pursuant to
         Rule 144A or has determined not to request such information and that it
         is aware that the transferor is relying upon its foregoing
         representations in order to claim the exemption from registration
         provided by Rule 144A or (y) an interest in a U.S. Global Security, the
         transfer of such interest may be effected only through the book entry
         system maintained by the Depository.

                  (ii)  If the proposed transferee is an Agent Member, and the
         Security to be transferred consists of U.S. Physical Securities, upon
         receipt by the Security Registrar of the documents referred to in
         clause (i) and instructions given in accordance with the Depository's
         and the Security Registrar's procedures, the Security Registrar shall
         reflect in the Security Register the date and an increase in the
         principal amount at maturity of the U.S. Global Security in an amount
         equal to the principal amount at maturity of the U.S. Physical
         Securities to be transferred, and the Trustee shall cancel the U.S.
         Physical Securities so transferred.

                  (b)   TRANSFERS TO NON-QIB INSTITUTIONAL ACCREDITED INVESTORS.
The following provisions shall apply with respect to the registration of any
proposed transfer of a Security to any Institutional Accredited Investor which
is not a QIB (excluding Non-U.S. Persons):

                  (i)   The Security Registrar shall register the transfer of
         any Security, whether or not such Security bears the Private Placement
         Legend, if (x) the requested transfer is after the time period referred
         to in Rule 144(k) under the Securities Act as in effect with respect to
         such transfer or (y) the proposed transferee has delivered to the
         Security

                                      48
<PAGE>

         Registrar (A) a certificate substantially in the form of EXHIBIT B
         hereto and (B) if the aggregate principal amount of the Notes being
         transferred is less than $250,000 at the time of such transfer, an
         Opinion of Counsel acceptable to the Company that such transfer is in
         compliance with the Securities Act.

                  (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 PHYSICAL SECURITIES. The following provisions shall apply with
respect to any transfer of interests in the Offshore Global Securities or
Offshore Physical Securities:

                  (i)   prior to removal of the Private Placement Legend from an
         Offshore Global Security or Offshore Physical Security pursuant to
         Section 2.05, the Security Registrar shall refuse to register such
         transfer unless such transfer complies with Section 3.07(a) or Section
         3.07(d), as the case may be; and

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

                  (d)   TRANSFERS TO NON-U.S. PERSONS AT ANY TIME. The following
provisions shall apply with respect to any transfer of a Security to a Non-U.S.
Person:

                  (i)   The Security Registrar shall register any proposed
         transfer to any Non-U.S. Person if the Security to be transferred is a
         U.S. Physical 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 (y) instructions 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 such 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 (B) if the proposed transferee is an Agent Member,
         upon receipt by the Security Registrar of 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 an increase in the principal amount of the
         Offshore Global Security in an amount equal to the principal amount
         of the U.S. Physical

                                      49
<PAGE>

         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.

                                      50

<PAGE>

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

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

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

                  The 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.

                                      51
<PAGE>

         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 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.

                                   ARTICLE 4.

                           Satisfaction and Discharge

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

                  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

                           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 have been complied with.

Notwithstanding the satisfaction and discharge of this Indenture pursuant to

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),

                           (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

                                       57
<PAGE>

                  (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 exercise of any power granted herein, or to enforce any other proper remedy.

Section 5.04. TRUSTEE MAY FILE PROOFS OF CLAIM.

                  In case of any judicial proceeding relative to the Company (or
any other 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 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.

                  Any money collected by the Trustee pursuant to this Article
shall be applied 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;

                  (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

                                       59
<PAGE>

                  (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

                                       60
<PAGE>

remedy given by this Article or by law to the Trustee or to the Holders may
be exercised from time to time, and as often as may be deemed expedient, by
the Trustee or by the Holders, as the case may be.

Section 5.12. CONTROL BY HOLDERS.

                  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

                  (1)  in the payment of the principal of (or premium, if any)
         or interest 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.

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.

Section 6.02. NOTICE OF DEFAULTS.

                  The Trustee shall give the Holders notice of any Default
hereunder as and to the extent provided by the Trust Indenture Act; PROVIDED,

thereof.

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

                  (d)  the Trustee may consult with counsel of its selection and

accordance with the applicable requirements of Section 6.11.

              (b)     The Trustee may resign at any time by giving written

competent jurisdiction for the appointment of a successor Trustee.

              (c)     The Trustee may be removed at any time by Act of the

              (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

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

              (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

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

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

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 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.

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

                                      67
<PAGE>

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 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.

              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

                                      68
<PAGE>

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.

         to Purchase, on or after the applicable Purchase Date), or

              (2)     reduce the percentage in principal amount at Stated

furnish the Trustee with the address thereof, such presentations, surrenders,
notices and demands may be made or served at the Corporate Trust Office of
the Trustee, and the Company hereby appoints the Trustee as its agent to
receive all such presentations, surrenders, notices and demands. In the event
any such notice or demands are so made or served on the Trustee, the Trustee
will promptly forward copies thereof to the Company.

               The Company may also from time to time designate one or more
other offices 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 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.

HOWEVER, that the Company shall not be required to preserve any

                                       76

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;

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.

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.

Section 10.08. LIMITATION ON CONSOLIDATED DEBT.

                  The Company shall not, and shall not permit any Restricted

and the receipt and application of the net proceeds therefrom (including,
without limitation, the application or use of the net proceeds therefrom to

Annualized Operating Cash Flow Ratio would be less than 7.0 to 1.0, or (b) in

                           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 Redeemable Stock), or any options,

                           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
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).

<PAGE>

                  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 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.

                                      81
<PAGE>

                  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

                                      82
<PAGE>

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) 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

                                      83
<PAGE>

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 nonassignment 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

                                      84
<PAGE>

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

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 of the occurrence of a Default or an Event of Default, an
Officers' Certificate 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 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

                                      85
<PAGE>

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 Notes
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

                                       86
<PAGE>

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 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 Notes and all holders of other Debt that is pari passu with the
Notes 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 Notes 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 Notes tendered into such Asset Sale Offer surrendered by
Holders thereof exceeds the amount of Excess Proceeds, the Trustee shall
select the Notes 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.

remain outstanding immediately after the occurrence of any such redemption

PROVIDED, FURTHER, that such redemption occurs within 60 days after
consummation of any such sale.

Section 11.02. APPLICABILITY OF ARTICLE.

               Redemption of Securities at the election of the Company, as
permitted by this Indenture and the provisions of the Securities, shall be

Section 11.03. ELECTION TO REDEEM; NOTICE TO TRUSTEE.

               The election of the Company to redeem any Securities pursuant
to Section 11.01 shall be evidenced by a Board Resolution. In case of any
redemption at the election of the Company pursuant to Section 11.01, the
Company shall, at least 45 days prior to the Redemption Date fixed by the
Company (unless a shorter notice shall be satisfactory to the Trustee),
notify the Trustee of such Redemption Date and of the principal amount of
Securities to be redeemed.

Section 11.04. SELECTION BY TRUSTEE OF SECURITIES TO BE REDEEMED.

               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,

               (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.

                                       89
<PAGE>

               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 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

                                       90

<PAGE>

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

                                       91
<PAGE>

         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 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).

                                       92
<PAGE>

               (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 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

                                       93
<PAGE>

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.

DONALDSON, LUFKIN & JENRETTE
SECURITIES CORPORATION
277 Park Avenue
New York, New York 10172

Ladies and Gentlemen:

                  Nextel Partners, Inc., a Delaware corporation (the "COMPANY"),
proposes to issue and sell to Donaldson, Lufkin & Jenrette Securities
Corporation, (the "INITIAL PURCHASER") an aggregate of $200,000,000 in principal
amount of its 11% Senior Notes due 2010 (the "SERIES A NOTES"), subject to the
terms and conditions set forth herein. The Series A Notes are to be issued
pursuant to the provisions of an indenture (the "INDENTURE"), to be dated as of
the Closing Date (as defined below), among the Company and The Bank of New York,
as trustee (the "TRUSTEE"). The Series A Notes and the Series B Notes (as
defined below) issuable in exchange therefor are collectively referred to
herein as the "NOTES." Capitalized terms used but not defined herein shall have
the meanings given to such terms in the Indenture.

                  The Company intends to use the gross proceeds from the sale to
the Initial Purchaser of the Series A Notes for general corporate purposes,
including to fund the Network Build-out (as defined in the Offering Memorandum),
operating losses and working capital through 2003.

                  1. OFFERING MEMORANDUM. The Series A Notes will be offered and
sold to the Initial Purchaser pursuant to one or more exemptions from the
registration requirements under the Securities Act of 1933, as amended (the
"ACT"). The Company has prepared a final offering memorandum, dated February 28,
2000 (the "OFFERING MEMORANDUM"), relating to the Series A Notes.

                  Upon original issuance thereof, and until such time as the
same is no longer required pursuant to the Indenture, the Series A Notes (and
all securities issued in exchange therefor, in substitution thereof or upon
conversion thereof) shall bear the following legend:

                  "THIS NOTE (OR ITS PREDECESSOR) HAS NOT BEEN REGISTERED UNDER
         THE U.S. SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"),
         AND, ACCORDINGLY, MAY NOT BE OFFERED, SOLD, PLEDGED OR

<PAGE>

         OTHERWISE TRANSFERRED WITHIN THE UNITED STATES OR TO, OR FOR THE
         ACCOUNT OR BENEFIT OF, U.S. PERSONS, EXCEPT AS SET FORTH IN THE NEXT
         SENTENCE. BY ITS ACQUISITION HEREOF OR OF A BENEFICIAL INTEREST HEREIN,
         THE HOLDER:

              (1) REPRESENTS THAT IT IS A "QUALIFIED INSTITUTIONAL BUYER" (AS
              DEFINED IN RULE 144A UNDER THE SECURITIES ACT) (A "QIB"),

              (2) AGREES THAT IT WILL NOT RESELL OR OTHERWISE TRANSFER THIS NOTE
              EXCEPT (A) TO THE COMPANY OR ANY OF ITS SUBSIDIARIES, (B) TO A
              PERSON WHOM THE SELLER REASONABLY BELIEVES IS A QIB PURCHASING FOR
              ITS OWN ACCOUNT OR FOR THE ACCOUNT OF A QIB IN A TRANSACTION
              MEETING THE REQUIREMENTS OF RULE 144A, (C) IN AN OFFSHORE
              TRANSACTION MEETING THE REQUIREMENTS OF RULE 903 OR 904 OF THE
              SECURITIES ACT, (D) IN A TRANSACTION MEETING THE REQUIREMENTS OF
              RULE 144 UNDER THE SECURITIES ACT, (E) TO AN INSTITUTIONAL
              "ACCREDITED INVESTOR" (AS DEFINED IN RULE 501(A)(1), (2), (3) OR
              (7) OF REGULATION D UNDER THE SECURITIES ACT) THAT, PRIOR TO SUCH
              TRANSFER, FURNISHES THE TRUSTEE A SIGNED LETTER CONTAINING CERTAIN
              REPRESENTATIONS AND AGREEMENTS RELATING TO THE TRANSFER OF THIS
              NOTE (THE FORM OF WHICH CAN BE OBTAINED FROM THE TRUSTEE) AND, IF
              SUCH TRANSFER IS IN RESPECT OF AN AGGREGATE PRINCIPAL AMOUNT OF
              NOTES LESS THAN $250,000, AN OPINION OF COUNSEL ACCEPTABLE TO THE
              COMPANY THAT SUCH TRANSFER IS IN COMPLIANCE WITH THE SECURITIES
              ACT, (F) IN ACCORDANCE WITH ANOTHER EXEMPTION FROM THE
              REGISTRATION REQUIREMENTS OF THE SECURITIES ACT (AND BASED UPON AN
              OPINION OF COUNSEL ACCEPTABLE TO THE COMPANY) OR (G) PURSUANT TO
              AN EFFECTIVE REGISTRATION STATEMENT AND, IN EACH CASE, IN
              ACCORDANCE WITH THE APPLICABLE SECURITIES LAWS OF ANY STATE OF
              THE UNITED STATES OR ANY OTHER APPLICABLE JURISDICTION AND

              (3) AGREES THAT IT WILL DELIVER TO EACH PERSON TO WHOM THIS NOTE
              OR AN INTEREST HEREIN IS TRANSFERRED A NOTICE SUBSTANTIALLY TO THE
              EFFECT OF THIS LEGEND.

         AS USED HEREIN, THE TERMS "OFFSHORE TRANSACTION" AND "UNITED STATES"
         HAVE THE MEANINGS GIVEN TO THEM BY RULE 902 OF REGULATION S UNDER THE
         SECURITIES ACT. THE INDENTURE CONTAINS A PROVISION REQUIRING THE
         TRUSTEE TO REFUSE TO REGISTER ANY TRANSFER OF THIS NOTE IN VIOLATION OF
         THE FOREGOING."

                  2. AGREEMENTS TO SELL AND PURCHASE.

                  On the basis of the representations, warranties and covenants
contained in this Agreement, and subject to the terms and conditions contained
herein, the Company agrees to issue and sell to the Initial Purchaser, and the
Initial Purchaser agrees to purchase from the Company, an aggregate principal
amount of $200,000,000 of Series A Notes at a purchase price equal to 97.5% of
the principal amount thereof (the "PURCHASE PRICE").

                  3. TERMS OF OFFERING.

                  The Initial Purchaser has advised the Company that the Initial
Purchaser will make offers (the "EXEMPT RESALES") of the Series A Notes
purchased hereunder on the terms set forth in the Offering Memorandum, as
amended or supplemented, solely to persons whom the Initial Purchaser reasonably
believes to be "qualified institutional buyers" as defined in Rule 144A under
the Act ("QIBS") (such persons specified in this clause being referred to herein
as the "ELIGIBLE PURCHASERS"). The Initial Purchaser will offer the Series A
Notes to Eligible Purchasers initially at a price equal to 100.0% of the
principal amount thereof. Such price may be changed at any time without notice.

                  Holders (including subsequent transferees) of the Series A
Notes will have the registration rights set forth in the registration rights
agreement (the "REGISTRATION RIGHTS AGREEMENT"), to be dated the Closing Date,
in substantially the form of Exhibit A hereto, for so long as such Series A
Notes constitute "TRANSFER RESTRICTED SECURITIES" (as defined in the
Registration Rights Agreement). Pursuant to the Registration Rights Agreement,
the Company will agree to file with the Securities and Exchange Commission (the
"COMMISSION") under the circumstances set forth therein, (i) a registration
statement under the Act (the "EXCHANGE OFFER REGISTRATION STATEMENT") relating
to the Company's 11% Series B Senior Notes due 2010 (the "SERIES B NOTES"), to
be offered in exchange for the Series A Notes (such offer to exchange being
referred to as the "EXCHANGE OFFER") and (ii) a shelf registration statement
pursuant to Rule 415 under the Act (the "SHELF REGISTRATION STATEMENT" and,
together with the Exchange Offer Registration Statement, the "REGISTRATION
STATEMENTS") relating to the resale by certain holders of the Series A Notes and
to use its best efforts to cause such Registration Statements to be declared and
remain effective and usable for the periods specified in the Registration Rights
Agreement and to consummate the Exchange Offer. This Agreement, the Indenture,
the Notes and the Registration Rights Agreement are hereinafter sometimes
referred to collectively as the "OPERATIVE DOCUMENTS."

                  4. DELIVERY AND PAYMENT.

                          (a) Delivery of, and payment of the Purchase Price
for, the Series A Notes shall be made at the offices of Latham & Watkins, 885
Third Avenue, Suite 1000, New York, New York, 10022, or such other location
as may be mutually acceptable. Such delivery and payment shall be made at
9:00 a.m. New York City time, on or before March 10, 2000 or at such other
time on the same date or such other date as shall be agreed upon by the
Initial

                                        3
<PAGE>

Purchaser and the Company in writing. The time and date of such delivery and the
payment for the Series A Notes are herein called the "CLOSING DATE."

                          (b) One or more of the Series A Notes in definitive
global form, registered in the name of Cede & Co., as nominee of the
Depository Trust Company ("DTC"), having an aggregate principal amount
corresponding to the aggregate principal amount of the Series A Notes
(collectively, the "GLOBAL NOTE"), shall be delivered by the Company to the
Initial Purchaser (or as the Initial Purchaser directs) in each case with any
transfer taxes thereon duly paid by the Company against payment by the
Initial Purchaser of the Purchase Price thereof by wire transfer in
immediately available funds to the order of the Company. The Global Note
shall be made available to the Initial Purchaser for inspection not later
than 9:30 a.m., Now York City time, on the business day immediately preceding
the Closing Date.

                  5. AGREEMENTS OF THE COMPANY.

                  The Company hereby agrees with the Initial Purchaser as
follows:

                          (a) To advise the Initial Purchaser promptly and,
if requested by the Initial Purchaser, confirm such advice in writing, (i) of
the issuance by any state securities commission of any stop order suspending
the qualification or exemption from qualification of any Series A Notes for
offering or sale in any jurisdiction designated by the Initial Purchaser
pursuant to Section 5(e) hereof, or the initiation of any proceeding by any
state securities commission or any other federal or state regulatory
authority for such purpose and (ii) of the happening of any event during the
period referred to in Section 5(c) below that makes any statement of a
material fact made in the Offering Memorandum untrue or that requires any
additions to or changes in the Offering Memorandum in order to make the
statements therein not misleading. The Company shall use all commercially
reasonable efforts to prevent the issuance of any stop order or order
suspending the qualification or exemption of any Series A Notes under any
state securities or Blue Sky laws and, if at any time any state securities
commission or other federal or state regulatory authority shall issue an
order suspending the qualification or exemption of any Series A Notes under
any state securities or Blue Sky laws, the Company shall use all commercially
reasonable efforts to obtain the withdrawal or lifting of such order at the
earliest possible time.

                          (b) To furnish the Initial Purchaser and those
persons identified by the Initial Purchaser to the Company as many copies of
the Offering Memorandum, and any amendments or supplements thereto, as the
Initial Purchaser may reasonably request for the time period specified in
Section 5(c). Subject to the Initial Purchaser's compliance with its
representations and warranties and agreements set forth in Section 7 hereof,
the Company consents to the use of the Offering Memorandum, and any
amendments and supplements thereto required pursuant hereto, by the Initial
Purchaser in connection with Exempt Resales.

                          (c) During such period as in the opinion of counsel
for the Initial Purchaser an Offering Memorandum is required by law to be
delivered in connection with Exempt Resales by the Initial Purchaser, (i) not
to make any amendment or supplement to the

                                        4
<PAGE>

Offering Memorandum of which the initial Purchaser shall not previously have
been advised or to which the Initial Purchaser shall reasonably object after
being so advised and (ii) to prepare promptly upon the Initial Purchaser's
reasonable request, any amendment or supplement to the Offering Memorandum
which may be necessary or advisable in connection with such Exempt Resales.

               (d)    If, during the period referred to in Section 5(c)
above, any event shall occur or condition shall exist as a result of which,
in the opinion of counsel to the Initial Purchaser, it becomes necessary to
amend or supplement the Offering Memorandum in order to make the statements
therein, in the light of the circumstances when such Offering Memorandum is
delivered to an Eligible Purchaser, not misleading, or if, in the opinion of
counsel to the Initial Purchaser, it is necessary to amend or supplement the
Offering Memorandum to comply with any applicable law, forthwith to prepare
an appropriate amendment or supplement to such Offering Memorandum so that
the statements therein, as so amended or supplemented, will not, in the light
of the circumstances when it is so delivered, be misleading, or so that such
Offering Memorandum will comply with applicable law, and to furnish to the
Initial Purchaser and such other persons as the Initial Purchaser may
designate such number of copies thereof as the Initial Purchaser may
reasonably request.

               (e)    Prior to the sale of all Series A Notes pursuant to
Exempt Resales as contemplated hereby, to cooperate with the Initial
Purchaser and counsel to the Initial Purchaser in connection with the
registration or qualification of the Series A Notes for offer and sale to the
Initial Purchaser and pursuant to Exempt Resales under the securities or Blue
Sky laws of such jurisdictions as the Initial Purchaser may request and to
continue such registration or qualification in effect so long as required for
Exempt Resales and to file such consents to service of process or other
documents as may be necessary in order to effect such registration or
qualification; PROVIDED, HOWEVER, that the Company shall not be required in
connection therewith to qualify as a foreign corporation in any jurisdiction
in which it is not now so qualified or to take any action that would subject
it to general consent to service of process or taxation other than as to
matters and transactions relating to the Offering Memorandum or Exempt
Resales, in any jurisdiction in which it is not now so subject.

               (f)    So long as the Notes are outstanding, (i) to furnish as
soon as practicable after the end of each fiscal year to the record holders
of the Notes a financial report of the Company and its subsidiaries on a
consolidated basis (and a similar financial report of all unconsolidated
subsidiaries, if any), all such financial reports to include a consolidated
balance sheet, a consolidated statement of operations, a consolidated
statement of cash flows and a consolidated statement of shareholders' equity
as of the end of and for such fiscal year, together with comparable
information as of the end of and for the preceding year, certified by the
Company's independent public accountants and (ii) to furnish as soon as
practicable after the end of each quarterly period (except for the last
quarterly period of each fiscal year) to such holders, a consolidated
balance sheet, a consolidated statement of operations and a consolidated
statement of cash flows (and similar financial reports of all unconsolidated
subsidiaries, if any) as of the end of and for such period, and for the
period from the beginning of such year to the close of

                                      5
<PAGE>

such quarterly period, together with comparable information for the
corresponding periods of the preceding year.

               (g)    So long as the Notes are outstanding, to furnish to the
Initial Purchaser as soon as available copies of all reports or other
communications furnished by the Company to its security holders or furnished
to or filed with the Commission or any national securities exchange on which
any class of securities of the Company is listed and such other publicly
available information concerning the Company and/or its subsidiaries as the
Initial Purchaser may reasonably request (without documents incorporated

material fact required to be stated therein or necessary to make the
statements therein, in the light of the circumstances under which they were
made, not misleading, except that the representations and warranties
contained in this paragraph (a) shall not apply to statements in or omissions
from the Offering Memorandum (or any supplement or amendment thereto) based

is in good standing as a foreign corporation authorized to do business in
each jurisdiction in which the nature of its business or its ownership or
leasing of property requires such qualification, except where the failure to
be so qualified would not have a material adverse effect on the business,
prospects, financial condition or results of operations of the Company and
its subsidiaries, taken as a whole (a "MATERIAL ADVERSE EFFECT").

               (c)    All outstanding shares of capital stock of the Company

whole, to which the Company or any of its subsidiaries is a party or by which
the Company or any of its subsidiaries or their respective property is bound.

               (k)    Except as disclosed in the Offering Memorandum, the
execution, delivery and performance of this Agreement and the other Operative
Documents by the Company, compliance by the Company with all provisions
hereof and thereof and the

                                       9

<PAGE>

consummation of the transactions contemplated hereby and thereby will not (i)
require any consent, approval, authorization or other order of, or
qualification with, any court or governmental body or agency (except such as
may be required under the securities or Blue Sky laws of the various states),
(ii) conflict with or constitute a breach of any of the terms or provisions
of, or a default under, the charter or by-laws of the Company or any of its
subsidiaries or any indenture, loan agreement, mortgage, lease or other
agreement or instrument that is material to the Company and its subsidiaries,
taken as a whole, to which the Company or any of its subsidiaries is a party
or by which the Company or any of its subsidiaries or their respective
property is bound, (iii) violate or conflict with any applicable law or any
rule, regulation, judgment, order or decree of any court or any governmental
body or agency having jurisdiction over the Company, any of its subsidiaries
or their respective property, (iv) result in the imposition or creation of
(or the obligation to create or impose) a Lien under, any agreement or
instrument to which the Company or any of its subsidiaries is a party or by
which the Company or any of its subsidiaries or their respective property is
bound, or (v) result in the termination, suspension or revocation of any
Authorization (as defined below) of the Company or any of its subsidiaries or
result in any other impairment of the rights of the holder of any such
Authorization.

                  (l)   Except as disclosed in the Offering Memorandum, there
are no legal or governmental proceedings pending or threatened to which the
Company or any of its subsidiaries is or could be a party or to which any of
their respective property is or could be subject, which would, if adversely
determined, result, singly or in the aggregate, in a Material Adverse Effect.

                  (m)   Neither the Company nor any of its subsidiaries has
violated any foreign, federal, state or local law or regulation relating to
the protection of human health and safety, the environment or hazardous or
toxic substances or wastes, pollutants or contaminants ("ENVIRONMENTAL
LAWS"), any provisions of the Employee Retirement Income Security Act of
1974, as amended ("ERISA"), or any provisions of the Foreign Corrupt
Practices Act or the rules and regulations promulgated thereunder, except for
such violations which, singly or in the aggregate, would not have a Material
Adverse Effect.

                  (n)   There are no costs or liabilities associated with
Environmental Laws (including, without limitation, any capital or operating
expenditures required for clean-up, closure of properties or compliance with
Environmental Laws or any Authorization, any related constraints on operating
activities and any potential liabilities to third parties) which would,
singly or in the aggregate, have a Material Adverse Effect.

                  (o)   Except as disclosed in the Offering Memorandum, each
of the Company and its subsidiaries has such permits, licenses, consents,
exemptions, franchises, authorizations and other approvals (each, an
"AUTHORIZATION") of, and has made all filings with and notices to, all
governmental or regulatory authorities and self-regulatory organizations and
all courts and other tribunals, including without limitation, under any
applicable Environmental Laws, as are necessary to own, lease, license and
operate its respective properties and to conduct its business, except where
the failure to have any such Authorization or to make any such filing

                                       10
<PAGE>

or notice would not, singly or in the aggregate, have a Material Adverse
Effect. Each such Authorization is valid and in full force and effect and
each of the Company and its subsidiaries is in compliance with all the terms
and conditions thereof and with the rules and regulations of the authorities
and governing bodies having jurisdiction with respect thereto; and no event
has occurred (including, without limitation, the receipt of any notice from
any authority or governing body) which allows or, after notice or lapse of
time or both, would allow, revocation, suspension or termination of any such
Authorization or results or, after notice or lapse of time or both, would
result in any other impairment of the rights of the holder of any such
Authorization; and such Authorizations contain no restrictions that are
burdensome to the Company or any of its subsidiaries; except where such
failure to be valid and in full force and effect or to be in compliance, the
occurrence of any such event or the presence of any such restriction would
not, singly or in the aggregate, have a Material Adverse Effect.

                  (p)   The PRO FORMA balance sheets included in the Offering
Memorandum have been prepared in accordance with generally accepted
accounting principles in the United States and give effect to assumptions
used in the preparation thereof on a reasonable basis and in good faith and
present fairly, in all material respects, the proposed transactions
contemplated by the Offering Memorandum. The other PRO FORMA financial and
statistical information and data included in the Offering Memorandum are, in
all material respects, accurately presented and prepared on a basis
consistent with the PRO FORMA balance sheet.

                  (q)   The Company is not and, after giving effect to the
offering and sale of the Series A Notes and the application of the net
proceeds thereof as described in the Offering Memorandum, will not be, an
"investment company," as such term is defined in the Investment Company Act
of 1940, as amended.

                  (r)   Other than the Amended and Restated Shareholders'
Agreement (as defined in the Offering Memorandum), the Restated Certificate
of Incorporation and the Registration Rights Agreement, there are no
contracts, agreements or understandings between the Company and any person
granting such person the right to require the Company to file a registration
statement under the Act with respect to any securities of the Company or to
require the Company to include such securities with the Notes registered
pursuant to any Registration Statement.

                  (s)   Neither the Company nor any of its subsidiaries nor
any agent thereof acting on the behalf of them has taken, and none of them
will take, any action that might cause this Agreement or the issuance or sale
of the Series A Notes to violate Regulation T (12 C.F.R. Part 220),
Regulation U (12 C.F.R. Part 221) or Regulation X (12 C.F.R. Part 224) of
the Board of Governors of the Federal Reserve System.

                  (t)   No "nationally recognized statistical rating
organization" as such term is defined for purposes of Rule 436(g)(2) under
the Act (i) has imposed (or has informed the Company that it is considering
imposing) any condition (financial or otherwise) on the Company's retaining
any rating assigned to the Company, any securities of the Company or (ii) has
indicated to the Company that it is considering (a) the downgrading,
suspension, or

                                       11
<PAGE>

withdrawal of, or any review for a possible change that does not indicate the
direction of the possible change in, any rating so assigned or (b) any change
in the outlook for any rating of the Company, or any securities of the
Company.

                  (u)   Since the respective dates as of which information is
given in the Offering Memorandum other than as set forth in the Offering
Memorandum (exclusive of any amendments or supplements thereto subsequent to

change or any development involving a prospective material adverse change in
the condition, financial or otherwise, or the earnings, business, management
or operations of the Company and its subsidiaries, taken as a whole, (ii)
there has not been any material adverse change or any development involving a
prospective material adverse change in the capital stock or in the long-term
debt of the Company or any of its subsidiaries and (iii) neither the Company
nor any of its subsidiaries has incurred any material liability or
obligation, direct or contingent.

                  (v)   The Offering Memorandum, as of its date, contains all
the information specified in, and meeting the requirements of, Rule
144A(d)(4) under the Act.

                  (w)   When the Series A Notes are issued and delivered
pursuant to this Agreement, the Series A Notes will not be of the same class
(within the meaning of Rule 144A under the Act) as any security of the
Company that is listed on a national securities exchange registered under
Section 6 of the Exchange Act or that is quoted in a United States automated
inter-dealer quotation system.

                  (x)   No form of general solicitation or general
advertising (as defined in Regulation D under the Act) was used by the
Company or any of its respective representatives (other than the Initial
Purchaser, as to whom the Company makes no representation) in connection with
the offer and sale of the Series A Notes contemplated hereby, including, but
not limited to, articles, notices or other communications published in any
newspaper, magazine, or similar medium or broadcast over television or radio,
or any seminar or meeting whose attendees have been invited by any general
solicitation or general advertising. No securities of the same class as the
Series A Notes have been issued and sold by the Company within the six-month
period immediately prior to the date hereof.

                  (y)   Prior to the effectiveness of any Registration
Statement, the Indenture is not required to be qualified under the TIA.

                  (z)   No registration under the Act of the Series A Notes
is required for the sale of the Series A Notes to the Initial Purchaser as
contemplated hereby or for the Exempt Resales assuming the accuracy of the
Initial Purchaser's representations and warranties and agreements set forth
in Section 7 hereof.

                  (aa)   Each certificate signed by any officer of the
Company and delivered to the Initial Purchaser or counsel for the Initial
Purchaser shall be deemed to be a representation and warranty by the Company
to the Initial Purchaser as to the matters covered thereby.

                                       12

         The Company acknowledges that the Initial Purchaser and, for
purposes of the opinions to be delivered to the Initial Purchaser pursuant to
Section 9 hereof, counsel to the Company and counsel to the Initial Purchaser
will rely upon the accuracy and truth of the foregoing representations and
hereby consents to such reliance.

         7.       INITIAL PURCHASER'S REPRESENTATIONS AND WARRANTIES.

         The Initial Purchaser represents and warrants to, and agrees with, the
Company:

                  (b)   Such Initial Purchaser (A) is not acquiring the

<PAGE>

counsel acceptable to the Company that such transfer is in compliance with
the Act, (VI) in accordance with another exemption from the registration

         8.       INDEMNIFICATION.

                  (a)   The Company agrees to indemnify and hold harmless the
Initial Purchaser, its directors, its officers and each person, if any, who
controls such Initial Purchaser within the meaning of Section 15 of the Act
or Section 20 of the Exchange Act, from and against any and all losses,
claims, damages, liabilities and judgments (including, without limitation,
any legal or other expenses incurred in connection with investigating or
defending any matter, including any action, that could give rise to any such
losses, claims, damages, liabilities or judgments) caused by any untrue
statement or alleged untrue statement of a material fact contained in the
Offering Memorandum (or any amendment or supplement thereto) or any Rule 144A
Information provided by the Company to any holder or prospective purchaser of
Series A Notes pursuant to Section 5(h) or caused by any omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, except insofar as
such losses, claims, damages, liabilities or judgments are caused by any such
untrue statement or omission or alleged untrue statement or omission based
upon information relating to the Initial Purchaser furnished in writing to
the Company by such Initial Purchaser.

                  (b)   The Initial Purchaser agrees to indemnify and hold
harmless the Company, and its directors and officers and each person, if any,
who controls (within the meaning of Section 15 of the Act or Section 20 of
the Exchange Act) the Company, to the same extent as the foregoing indemnity
from the Company to the Initial Purchaser but only with reference to
information relating to the Initial Purchaser furnished in writing to the
Company by the Initial Purchaser expressly for use in the Offering Memorandum.

                  (c)   In case any action shall be commenced involving any
person in respect of which indemnity may be sought pursuant to Section 8(a)
or 8(b) (the "INDEMNIFIED PARTY"), the indemnified party shall promptly
notify the person against whom such indemnity may be sought (the
"INDEMNIFYING PARTY") in writing and the indemnifying party shall assume the
defense of such action, including the employment of counsel reasonably
satisfactory to the indemnified party and the payment of all fees and
expenses of such counsel, as incurred (except that in the case of any action
in respect of which indemnity may be sought pursuant to both

                                       14

<PAGE>

Sections 8(a) and 8(b), the Initial Purchaser shall not be required to assume
the defense of such action pursuant to this Section 8(c), but may employ
separate counsel and participate in the defense thereof, but the fees and
expenses of such counsel, except as provided below, shall be at the expense of
the Initial Purchaser). Any indemnified party shall have the right to employ
separate counsel in any such action and participate in the defense thereof, but
the fees and expenses of such counsel shall be at the expense of the indemnified
party unless (i) the employment of such counsel shall have been specifically
authorized in writing by the indemnifying party, (ii) the indemnifying party
shall have failed to assume the defense of such action or employ counsel
reasonably satisfactory to the indemnified party or (iii) the named parties to
any such action (including any impleaded parties) include both the indemnified
party and the indemnifying party, and the indemnified party shall have been
advised by such counsel that there may be one or more legal defenses available
to it which are different from or additional to those available to the
indemnifying party (in which case the indemnifying party shall not have the
right to assume the defense of such action on behalf of the indemnified party).
In any such case, the indemnifying party shall not, in connection with any one
action or separate but substantially similar or related actions in the same
jurisdiction arising out of the same general allegations or circumstances, be
liable for the fees and expenses of more than one separate firm of attorneys (in
addition to any local counsel) for all indemnified parties and all such fees and
expenses shall be reimbursed as they are incurred. Such firm shall be designated
in writing by Donaldson, Lufkin & Jenrette Securities Corporation, in the case
of the parties indemnified pursuant to Section 8(a), and by the Company, in the
case of parties indemnified pursuant to Section 8(b). The indemnifying party
shall indemnify and hold harmless the indemnified party from and against any and
all losses, claims, damages, liabilities and judgments by reason of any
settlement of any action (i) effected with its written consent or (ii) effected
without its written consent if the settlement is entered into more than twenty
business days after the indemnifying party shall have received a request from
the indemnified party for reimbursement for the fees and expenses of counsel (in
any case where such fees and expenses are at the expense of the indemnifying
party) and, prior to the date of such settlement, the indemnifying party shall
have failed to comply with such reimbursement request. No indemnifying party
shall, without the prior written consent of the indemnified party, effect any
settlement or compromise of, or consent to the entry of judgment with respect
to, any pending or threatened action in respect of which the indemnified party
is or could have been a party and indemnity or contribution may be or could have
been sought hereunder by the indemnified party, unless such settlement,
compromise or judgment (i) includes an unconditional release of the indemnified
party from all liability on claims that are or could have been the subject
matter of such action and (ii) does not include a statement as to or an
admission of fault, culpability or a failure to act, by or on behalf of the
indemnified party.

                  (d) To the extent the indemnification provided for in this
Section 8 is unavailable to an indemnified party or insufficient in respect of
any losses, claims, damages, liabilities or judgments referred to therein, then
each indemnifying party, in lieu of indemnifying such indemnified party, shall
contribute to the amount paid or payable by such indemnified party as a result
of such losses, claims, damages, liabilities and judgments (i) in such
proportion as is appropriate to reflect the relative benefits received by the
Company, on the one hand, and the Initial Purchaser on the other hand from the
offering of the Series A Notes or (ii) if the allocation

                                       15

<PAGE>

provided by clause 8(d)(i) above is not permitted by applicable law, in such
proportion as is appropriate to reflect not only the relative benefits referred
to in clause 8(d)(i) above but also the relative fault of the Company, on the
one hand, and the Initial Purchaser, on the other hand, in connection with the
statements or omissions which resulted in such losses, claims, damages,
liabilities or judgments, as well as any other relevant equitable
considerations. The relative benefits received by the Company, on the one hand
and the Initial Purchaser, on the other hand, shall be deemed to be in the same
proportion as the total net proceeds from the offering of the Series A Notes
(after underwriting discounts and commissions, but before deducting expenses)
received by the Company, and the total discounts and commissions received by the
Initial Purchaser bear to the total price to investors of the Series A Notes, in
each case as set forth in the table on the cover page of the Offering
Memorandum. The relative fault of the Company, on the one hand, and the Initial
Purchaser, on the other hand, shall be determined by reference to, among other
things, whether the untrue or alleged untrue statement of a material fact or the
omission or alleged omission to state a material fact relates to information
supplied by the Company, on the one hand, or the Initial Purchaser, on the other
hand, and the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission.

              The Company and the Initial Purchaser agree that it would not be
just and equitable if contribution pursuant to this Section 8(d) were determined
by pro rata allocation or by any other method of allocation which does not take
account of the equitable considerations referred to in the immediately preceding
paragraph. The amount paid or payable by an indemnified party as a result of the
losses, claims, damages, liabilities or judgments referred to in the immediately
preceding paragraph shall be deemed to include, subject to the limitations set
forth above, any legal or other expenses incurred by such indemnified party in
connection with investigating or defending any matter, including any action,
that could have given rise to such losses, claims, damages, liabilities or
judgments. Notwithstanding the provisions of this Section 8, the Initial
Purchaser shall not be required to contribute any amount in excess of the amount
by which the total discounts and commissions received by such Initial Purchaser
exceeds the amount of any damages which such Initial Purchaser has otherwise
been required to pay by reason of such untrue or alleged untrue statement or
omission or alleged omission. No person guilty of fraudulent misrepresentation
(within the meaning of Section 11(f) of the Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent
misrepresentation.

                  (e) The remedies provided for in this Section 8 are not
exclusive and shall not limit any rights or remedies which may otherwise be
available to any indemnified party at law or in equity.

              9.  CONDITIONS OF INITIAL PURCHASER'S OBLIGATIONS.

              The obligations of the Initial Purchaser to purchase the Series A
Notes under this Agreement are subject to the satisfaction of each of the
following conditions:

                                       16

<PAGE>

                  (a)   All the representations and warranties of the Company
contained in this Agreement shall be true and correct on the Closing Date with
the same force and effect as if made on and as of the Closing Date.

                  (b)   On or after the date hereof, (i) there shall not have
occurred any downgrading, suspension or withdrawal of nor shall any notice
have been given of any potential or intended downgrading, suspension or
withdrawal of, or of any review (or of any potential or intended review) for
a possible change that does not indicate the direction of the possible change
in, any rating of the Company or any securities of the Company (including,
without limitation, the placing of any of the foregoing ratings on credit
watch with negative or developing implications or under review with an
uncertain direction) by any "nationally recognized statistical rating
organization" as such term is defined for purposes of Rule 436(g)(2) under
the Act, (ii) there shall not have occurred any change, nor shall any notice
have been given of any potential or intended change, in the outlook for any
rating of the Company or any securities of the Company by any such rating
organization and (iii) no such rating organization shall have given notice
that it has assigned (or is considering assigning) a lower rating to the
Notes than that on which the Notes were marketed.

                  (c)   Since the respective dates as of which information is
given in the Offering Memorandum other than as set forth in the Offering
Memorandum (exclusive of any amendments or supplements thereto subsequent to the
date of this Agreement), (i) there shall not have occurred any change or any
development involving a prospective change in the condition, financial or
otherwise, or the earnings, business, management or operations of the Company
and its subsidiaries, taken as a whole, (ii) there shall not have been any
change or any development involving a prospective change in the capital stock or
in the long-term debt of the Company or any of its subsidiaries and (iii)
neither the Company nor any of its subsidiaries shall have incurred any
liability or obligation, direct or contingent, the effect of which, in any such
case described in clause 9(c)(i), 9(c)(ii) or 9(c)(iii), in your judgment, is
material and adverse and, in your judgment, makes it impracticable to market the
Series A Notes on the terms and in the manner contemplated in the Offering
Memorandum.

                  (d)   You shall have received on the Closing Date a
certificate dated the Closing Date, signed by the President and the Chief
Financial Officer of the Company, confirming the matters set forth in Sections
9(a), 9(b) and 9(c) and stating that the Company has complied with all the
agreements and satisfied all of the conditions herein contained and required to
be complied with or satisfied on or prior to the Closing Date.

                  (e)   You shall have received on the Closing Date an opinion
(satisfactory to you and counsel for the Initial Purchaser), dated the Closing
Date, of Friedman Kaplan & Seiler, special counsel for the Company to the effect
that:

                        (i)       each of the Company and its subsidiaries has

                  business in each jurisdiction in which the nature of its
                  business or its ownership or leasing of property requires such
                  qualification, except where the failure to be so qualified
                  would not have a Material Adverse Effect;

                        (iii)     all the outstanding shares of capital stock of
                  the Company as set forth in the Offering Memorandum have been
                  duly authorized and validly issued and are fully paid,

                  Restated Certificate of Incorporation or the Amended and
                  Restated Shareholders' Agreement;

                        (iv)      all of the outstanding shares of capital stock
                  of each of the Company's subsidiaries have been duly
                  authorized and validly issued and are fully paid and
                  non-assessable, and, to the best of such counsel's knowledge,

                  of equitable remedies may be limited by equitable principles
                  of general applicability;

                  duly authorized, executed and delivered by the Company and is

                        (xi)      Except for the post-closing authorizations and
                  approvals referred to in the Offering Memorandum, the

                  lease or other agreement or instrument that is material to the

                  suspension or revocation of any Authorization (as defined
                  above) of the Company or any of its subsidiaries or result in
                  any other impairment of the rights of the holder of any such
                  Authorization except as enforcement of rights to indemnity or
                  contribution may be limited by Federal or state securities
                  laws or principles of public policy;

                           (xii) the Company is not and, after giving effect to
                  the offering and sale of the Series A Notes and the
                  application of the net proceeds thereof as described in the
                  Offering Memorandum, will not be, an "investment company" as
                  such term is defined in the Investment Company Act of 1940, as
                  amended;

                           (xiii) the Indenture complies as to form in all
                  material respects with the requirements of the TIA, and the
                  rules and regulations of the Commission applicable to an
                  indenture which is qualified thereunder. It is not necessary
                  in connection with the offer, sale and delivery of the Series
                  A Notes to the Initial Purchaser in the manner contemplated by
                  this Agreement or in connection with the Exempt Resales to
                  qualify the Indenture under the TIA;

                           (xiv) no registration under the Act of the Series A
                  Notes is required for the sale of the Series A Notes to the
                  Initial Purchaser as contemplated by this Agreement or for the
                  Exempt Resales assuming that (i) the Initial Purchaser is a
                  QIB, (ii) the accuracy of, and compliance with, the Initial
                  Purchaser's representations and agreements contained in
                  Section 7 of this Agreement, (iii) the accuracy of the
                  representations of the Company set forth in Sections 6(v), (w)
                  and (x) of this Agreement; and

                           (xv) after due inquiry, such counsel does not know of
                  any legal or governmental proceedings pending or threatened to
                  which the Company or any of its subsidiaries is or could be a
                  party or to which any of their respective property is or could
                  be subject, which might result, singly or in the aggregate, in
                  a Material Adverse Effect.

         Nothing has come to the attention of such counsel that has led them
to believe that, as of the date of the Offering Memorandum or as of the
Closing Date, the Offering Memorandum, as amended or supplemented, if
applicable (except for the financial data included therein (including the
supporting notes), as to which such counsel does not express any belief)
contains any untrue statement of a material fact or omits to state a material
fact necessary in order to make the statements therein, in the light of the
circumstances under which they were made, not misleading.

         The statement of Friedman Kaplan & Seiler, in the penultimate
paragraph of this section 9(e) shall be rendered to you at the request of the
Company and shall so state therein. In

                                       20
<PAGE>

providing such statement with respect to the matters covered by the penultimate
paragraph of this Section 9(e), Friedman Kaplan & Seiler, may state that their
statement is based upon their participation in the preparation of the Offering
Memorandum and any amendments or supplements thereto and review and discussion
of the contents thereof, but is without independent check or verification except
as specified.

                  (f) You shall have received on the Closing Date an opinion
(satisfactory to you and counsel for the Initial Purchaser), dated the Closing
Date, of Willkie Farr & Gallagher, special FCC counsel for the Company, to the
effect that:

                           (i) The execution and delivery by the Company of, and
                  the performance by the Company of its obligations under, this
                  Agreement and any other agreement executed in connection with
                  the transactions contemplated thereby do not violate (i) the
                  Federal Communications Act of 1934, as amended (the
                  "Communications Act"), (ii) any rules or regulations of the
                  Federal Communications Commission ("FCC") applicable to the
                  Company, or (iii) to the best of such counsel's knowledge, any
                  decree from any court or tribunal, and (B) no authorization of
                  or filing with the FCC is necessary for the execution and
                  delivery of or the performance by the Company of its
                  obligations under this Agreement or any other agreement
                  executed in connection with the transactions contemplated
                  thereby in accordance with the terms thereof, except such as
                  have been obtained;

                           (ii) The Company and its subsidiaries have all
                  certificates, orders, permits, licenses, authorizations,
                  consents and approvals of and from, and have made all reports,
                  filings and registrations with, and paid all fees required by,
                  the FCC necessary to own, lease, license and use its
                  properties and assets and to conduct its business in the
                  manner described in the Offering Memorandum, except where such
                  failure would not materially affect their business operations
                  as a whole; and (B) to the best of such counsel's knowledge,
                  the Company and each subsidiary have not received any notice
                  of proceedings relating to the violation, revocation or
                  modification of any such certificates, orders, permits,
                  licenses, authorizations, consents or approvals, or the
                  qualifications or rejection of any such filing or
                  registration, the effect of which, singly or in the aggregate,
                  would have a Material Adverse Effect on the business or
                  operations of the Company and its subsidiaries, taken as a
                  whole;

                  of, or in default under, the Communications Act or the
                  telecommunications rules or regulations of the FCC, the effect
                  of which, singly or in the aggregate, would have a Material

                           (iv) To the best of such counsel's knowledge (A) no
                  adverse judgment, decree or order of the FCC has been issued
                  against the Company or any of its subsidiaries and (B) no
                  litigation, proceeding inquiry or investigation has been
                  commenced or threatened against the Company or any of its
                  subsidiaries before or by the FCC which, if decided adversely
                  to its interest, would have a Material Adverse Effect on the
                  Company and its subsidiaries, taken as a whole; and

                           (v) The statements set forth in the Offering
                  Memorandum under captions "Risk Factors--Risk Factors
                  Relating To Our Industry--Regulatory authorities exercise
                  considerable power over our operations, which could be
                  exercised against our interests and impose additional
                  unanticipated costs" and "Regulation", insofar as they purport
                  to describe the provisions of the laws and documents referred
                  to therein, are accurate, complete and fair;

                               Nothing has come to the attention of such
                  counsel that has led them to believe that, as of the date of
                  the Offering Memorandum or as of the Closing Date, the
                  Offering Memorandum, as amended or supplemented, if applicable
                  (except for the financial statements and other financial data
                  included therein (including the supporting notes), as to which
                  such counsel does not express any belief) contains any untrue
                  statement of a material fact or omits to state a material fact
                  necessary in order to make the statements therein, in the
                  light of the circumstances under which they were made, not
                  misleading.

         The statement of Willkie Farr & Gallagher in the penultimate paragraph
of this Section 9(f) shall be rendered to you at the request of the Company and
shall so state therein. In providing such statement with respect to the matters
covered by the penultimate paragraph of this Section 9(f), Willkie Farr &
Gallagher may state that their statement is based upon their participation in
the preparation of the Offering Memorandum and any amendments or supplements
thereto and review and discussion of the contents thereof, but is without
independent check or verification except as specified.

                  (g) You shall have received on the Closing Date an opinion
(satisfactory to you and counsel for the Initial Purchaser), dated the Closing
Date, of Donald Manning, Esq., general counsel of the Company, to the effect
that:

                           (i) each of the Company and its subsidiaries has such
                  Authorizations of, and has made all filings with and notices
                  to, all governmental or regulatory authorities and
                  self-regulatory organizations and all courts and other
                  tribunals, including without limitation, under any applicable
                  Environmental Laws, as are necessary to own, lease, license
                  and operate its respective properties and to conduct its
                  business, except where the failure to have any such
                  Authorization or to make any such

                                       22
<PAGE>

                  filing or notice would not reasonably be expected to, singly
                  or in the aggregate, have a Material Adverse Effect and except
                  for such matters as are disclosed in the Offering Memorandum.
                  Each such Authorization is valid and in full force and effect
                  and each of the Company and its subsidiaries is in compliance
                  with all the terms and conditions thereof and with the rules
                  and regulations of the authorities and governing bodies having
                  jurisdiction with respect thereto; and to the best of such
                  counsel's knowledge, no event has occurred (including the
                  receipt of any notice from any authority or governing body)
                  which allows or, after notice or lapse of time or both, would
                  allow, revocation, suspension or termination of any such
                  Authorization or results or, after notice or lapse of time or
                  both, would result in any other impairment of the rights of
                  the holder of any such Authorization; except where such
                  failure to be valid and in full force and effect or to be in
                  compliance or the occurrence of any such event would not
                  reasonably be expected to, singly or in the aggregate, have a
                  Material Adverse Effect and except for such matters as are
                  disclosed in the Offering Memorandum;

                           (ii) neither the Company nor any of its subsidiaries
                  is in violation of its respective charter or by-laws and, to
                  the best of such counsel's knowledge after due inquiry,
                  neither the Company nor any of its subsidiaries is in default
                  in the performance of any obligation, agreement, covenant or
                  condition contained in any indenture, loan agreement,
                  mortgage, lease or other agreement or instrument that is
                  material to the Company and its subsidiaries, taken as a
                  whole, to which the Company or any or its subsidiaries is a
                  party or by which the Company or any of its subsidiaries or
                  their respective property is bound; and

                           (iii) to the best of such counsel's knowledge after
                  due inquiry other than the Amended and Restated Shareholders'
                  Agreement and the Resated Certificate of Incorporation, there
                  are no contracts, agreements or understandings between the
                  Company and any person granting such person the right to
                  require the Company to file a registration statement under the
                  Act with respect to any securities of the Company or to
                  require the Company to include such securities with the Notes
                  registered pursuant to any Registration Statement.
