to take any action under any provision of this Indenture, the Company shall
furnish to the Trustee an Officer's Certificate stating that all conditions
precedent, if any, provided for in this Indenture (including any covenant
compliance with which constitutes a condition precedent) relating to the
proposed action have been complied with and an Opinion of Counsel stating that
in the opinion of such counsel all such conditions precedent, if any, have been
complied with, except that in the case of any such application or request as to
which the furnishing of such documents is specifically required by any provision
of this Indenture relating to such particular application or request, no
additional certificate or opinion need be furnished.

                  Every certificate or opinion with respect to compliance with a

         individual, such condition or covenant has been complied with.


SECTION 103.  Form of Documents Delivered to Trustee.


                  In any case where several matters are required to be certified
by, or covered by an opinion of, any specified Person, it is not necessary that
all such matters be certified by, or covered by the opinion of, only one such
Person, or that they be so certified or covered by only one document, but one
such Person may certify or give an opinion with respect to some matters and one
or more other such Persons as to other matters, and any such Person may certify
or give an opinion as to such matters in one or several documents.

                  Any certificate or opinion of an officer of the Company may be
based, insofar as it relates to legal matters, upon a certificate or opinion of,
or representations by, counsel, unless such officer knows, or in the exercise of
reasonable care should know, that the certificate or opinion or representations
with respect to the matters upon which his certificate or opinion is based are
erroneous. Any such certificate or Opinion of Counsel may be based, insofar as
it relates to factual matters, upon a certificate or opinion of, or
representations by, an officer or

   28

                                                                              22


officers of the Company stating that the information with respect to such
factual matters is in the possession of the Company, unless such counsel knows,
or in the exercise of reasonable care should know, that the certificate or
opinion or representations with respect to such matters are erroneous.

                  Where any Person is required to make, give or execute two or
more applications, requests, consents, certificates, statements, opinions or
other instruments under this Indenture, they may, but need not, be consolidated
and form one instrument.

SECTION 104.  Acts of Holders.

                  (a) Any request, demand, authorization, direction, notice,
consent, waiver or other action provided by this Indenture to be given or taken
by Holders may be embodied in and evidenced by one or more instruments of
substantially similar tenor signed by such Holders in person or by agents duly
appointed in writing; and, except as herein otherwise expressly provided, such
action shall become effective when such instrument or instruments are delivered
to the Trustee and, where it is hereby expressly required, to the Company. Such
instrument or instruments (and the action embodied therein and evidenced
thereby) are herein sometimes referred to as the "Act" of the Holders signing
such instrument or instruments. Proof of execution of any such instrument or of
a writing appointing any such agent shall be sufficient for any purpose of this
Indenture and conclusive in favor of the Trustee and the Company, if made in the
manner provided in this Section.

                  (b) The fact and date of the execution by any Person of any
such instrument or writing may be proved by the affidavit of a witness of such
execution or by a certificate of a notary public or other officer authorized by
law to take acknowledgments of deeds, certifying that the 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 constitute sufficient proof
of authority. The fact and date of the execution of any such instrument or
writing, or the authority of the Person executing the same, may also be proved
in any other manner that the Trustee deems sufficient.

                  (c) The principal amount and serial numbers of Notes held by
any Person, and the date of holding the same, shall be proved by the Register.

                  (d) If the Company shall solicit from the Holders of Notes any
request, demand, authorization, direction, notice, consent, waiver or other Act,
the Company may, at its option, by or pursuant to a Board Resolution, fix in
advance a record date for the determination of Holders entitled to give such
request, demand, authorization, direction, notice, consent, waiver or other Act,
but the Company shall have no obligation to do so. Notwithstanding TIA Section
316(c), such record date shall be the record date specified in or pursuant to
such Board Resolution, which shall be a date not earlier than the date 30 days
prior to the first solicitation of Holders generally in connection therewith and
not later than the date such solicitation is completed. If such a record date is
fixed, such request, demand, authorization, direction, notice, consent, waiver
or other Act may be given before or after such record date, but only the Holders
of record at the close of business on such record date shall be deemed to be
Holders for the purposes of determining whether Holders of the requisite
proportion of Outstanding Notes have authorized or agreed or consented to such
request, demand, authorization, direction, notice, consent, waiver or

   29

                                                                              23

other Act, and for that purpose the Outstanding Notes shall be computed as of
such record date; provided that no such authorization, agreement or consent by
the Holders on such record date shall be deemed effective unless it shall become
effective pursuant to the provisions of this Indenture not later than eleven
months after the record date.

                  (e) Any request, demand, authorization, direction, notice,
consent, waiver or other Act of the Holder of any Note shall bind every future
Holder of the same Note and the Holder of every Note 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 Note.

SECTION 105.   Notices, Etc., to Trustee, 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 to or with the Trustee at its Corporate Trust Office,
         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 Indenture, or at any
         other address previously furnished in writing to the Trustee by the
         Company.

SECTION 106.   Notice to Holders; Waiver.

                  Where this Indenture provides for notice of any event to
Holders by the Company or the Trustee, 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 Register, not later than the latest date, and not
earlier than the earliest date, 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. Any notice
mailed to a Holder in the manner herein prescribed shall be conclusively deemed
to have been received by such Holder, whether or not such Holder actually
receives such notice. Where this Indenture provides for notice in any manner,
such notice may be waived in writing by the Person entitled to receive such
notice, either before or after the event, and such waiver shall be the
equivalent of such notice. Waivers of notice by Holders shall be filed with the
Trustee, but such filing shall not be a condition precedent to the validity of
any action taken in reliance upon such waiver.

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

   30

                                                                              24

SECTION 107.  Effect of Headings and Table of Contents.

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

SECTION 108.  Successors and Assigns.

                  All covenants and "agreements" in this Indenture by the
Company shall bind its successors and assigns, whether so expressed or not.

SECTION 109.  Separability Clause.

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

SECTION 110.  Benefits of Indenture.

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

SECTION 111.  Governing Law.

                  This Indenture and the Notes shall be governed by and
construed in accordance with the laws of the State of New York. This Indenture
is subject to the provisions of the Trust Indenture Act that are required to be

Indenture or the Notes and waives any rights to which it may be entitled on
account of place of residence or domicile.

SECTION 112.  Legal Holidays.

                  In any case where any Interest Payment Date, Redemption Date,
sinking fund payment date or Stated Maturity or Maturity of any Note shall not
be a Business Day, then (notwithstanding any other provision of this Indenture
or of the Notes) payment of principal (or premium, if any) or interest need not
be made on such date, but may be made on the next succeeding Business Day with
the same force and effect as if made on such Interest Payment Date, Redemption
Date or sinking fund payment date, or at the Stated Maturity or Maturity;
provided that no interest shall accrue for the period from and after such
Interest Payment Date, Redemption Date, sinking fund payment date, Stated
Maturity or Maturity, as the case may be.

the Notes may be manual or facsimile signatures of the present or any future
such authorized officer and may be imprinted or otherwise reproduced on the
Notes.

                  Notes bearing the manual or facsimile signatures of
individuals who were at any time the proper officers of the Company shall bind

to hold such offices prior to the authentication and delivery of such Notes or
did not hold such offices at the date of such Notes.

Company to the Trustee for authentication, together with a Company Order for
the authentication and delivery of such Notes directing the Trustee to
authenticate the Notes and certifying that all conditions precedent to the
issuance of Notes contained herein have been fully complied with, and the

and an Opinion of Counsel of the Company that it may reasonably request in
connection with such authentication of Notes. Such order shall specify the
amount of Notes to be authenticated and the date on which the original issue of
Notes is to be authenticated.

or be valid or obligatory for any purpose unless there appears on such Note a
certificate of authentication, substantially in the form provided for in
Exhibit A, duly executed by the Trustee by manual signature of an authorized
officer, and such certificate upon any Note shall be conclusive evidence, and
the only evidence, that such Note has been duly authenticated and delivered
hereunder and is entitled to the benefits of this Indenture.

                  In case the Company, pursuant to Article Eight, shall be
consolidated or merged with or into any other Person or shall convey, transfer,
lease or otherwise dispose of its properties and assets substantially as an
entirety in a transaction or a series of transactions to any Person, and the
successor Person resulting from such consolidation, or surviving such merger,
or into which the Company shall have been merged, or the Person which shall
have received a conveyance, transfer, lease or other disposition as aforesaid,
shall have executed an indenture supplemental hereto with the Trustee pursuant
to Article Eight, any of the Notes authenticated or delivered prior to such
consolidation, merger, conveyance, transfer, lease or other disposition may,
from time to time, at the request of the successor Person, be exchanged for
other Notes executed in the name of the successor Person with such changes in
phraseology and form as may be appropriate, but otherwise in substance of like
tenor as the Notes surrendered for such exchange and of like principal amount;
and the Trustee, upon Company Request of the successor Person, shall
authenticate and deliver Notes as specified in such request for the purpose of
such exchange. If Notes shall at any time be authenticated and delivered in any
new name of a successor Person pursuant to this Section in exchange or
substitution for or upon registration of transfer of any Notes, such successor
Person, at the option of the Holders but without expense to them, shall provide
for the exchange of all Notes at the time Outstanding for Notes authenticated
and delivered in such new name.

                                                                              28


SECTION 304. Temporary Notes.

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

                  If temporary Notes are issued, the Company shall cause
definitive Notes to be prepared without unreasonable delay. After the
preparation of definitive Notes, the temporary Notes shall be exchangeable for
definitive Notes upon surrender of the temporary Notes at the office or agency
of the Company designated for such purpose pursuant to Section 1002 without
charge to the Holder. Upon surrender for cancellation of any one or more
temporary Notes, the Company shall execute and upon Company Order the Trustee
shall authenticate and deliver in exchange therefor a like principal amount of
definitive Notes of authorized denominations. Until so exchanged, the temporary
Notes shall in all respects be entitled to the same benefits under this
Indenture as definitive Notes.

SECTION 305. 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 1002 being herein
sometimes referred to as the "Register") in which, subject to such reasonable
regulations as it may prescribe, the Company shall provide for the registration
of Notes and of transfers of Notes. The Register shall be in written form or
any other form capable of being converted into written form within a reasonable
time. At all reasonable times, the Register shall be open to inspection by the
Trustee. The Trustee is hereby initially appointed as security registrar (the
"Registrar") for the purpose of registering Notes and transfers of Notes as
herein provided.

                  Upon surrender for registration of transfer of any Note at
the office or agency of the Company designated pursuant to Section 1002, the
Company shall execute, and the Trustee shall authenticate and deliver, in the
name of the designated transferee or transferees, one or more new Notes of any
authorized denomination or denominations of a like aggregate principal amount.

                  At the option of the Holder, Notes may be exchanged for other
Notes of any authorized denomination and of a like aggregate principal amount,
upon surrender of the Notes to be exchanged at such office or agency. Whenever
any Notes are so surrendered for exchange, the Company shall execute, and the
Trustee shall authenticate and deliver, the Notes which the Holder making the
exchange is entitled to receive.

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

                  Every Note presented or surrendered for registration of
transfer or for exchange

   35
                                                                              29


shall be duly endorsed and be accompanied by a written instrument of transfer,
in form satisfactory to the Company and the 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 or redemption of Notes, 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
Notes, other than exchanges pursuant to Section 304, 906, 1010, 1017 or 1108
not involving any transfer.

                  The Company shall not be required (i) to issue, register the
transfer of or exchange any Note during a period beginning at the opening of
business 15 days before the selection of Notes to be redeemed under Section
1104 and ending at the close of business on the day of such mailing of the
relevant notice of redemption, or (ii) to register the transfer of or exchange
any Note so selected for redemption in whole or in part, except the unredeemed
portion of any Note being redeemed in part.

SECTION 306. Mutilated, Destroyed, Lost and Stolen Notes.

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

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

                  Upon the issuance of any new Note under this Section 306, 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 Note issued pursuant to this Section 306 in lieu of
any mutilated, destroyed, lost or stolen Note shall constitute an original
additional contractual obligation of the Company, whether or not the mutilated,
destroyed, lost or stolen Note shall be at any time enforceable by anyone, and
shall be entitled to all benefits of this Indenture equally and proportionately
with any and all other Notes duly issued hereunder.

                  The provisions of this Section 306 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 Notes.

   36

                                                                              30


SECTION 307. Payment of Interest; Interest Rights Preserved.

                  Interest on any Note 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 such Note (or Predecessor Notes) is registered at the close of
business on the Regular Record Date (or if a Predecessor Note is outstanding on
such Regular Record Date, such Predecessor Note) for such interest at the
office or agency of the Company maintained for such purpose pursuant to Section
1002 or, at the option of the Company, interest may be paid by check mailed to
the address of the Person entitled thereto as such address shall appear on the
Register; provided that all payments with respect to Global Notes the Holders
of which have given wire transfer instructions to the Company will be required
to be made by wire transfer of immediately available funds to the accounts
specified by the Holders thereof.

                  Any interest on any Note which is payable, but is not
punctually paid or duly provided for, on any Interest Payment Date shall
forthwith cease to be payable to the Holder on the Regular Record Date by
virtue of having been such Holder, and such defaulted interest and (to the
extent lawful) interest on such defaulted interest at the rate borne by the
Notes (such defaulted interest and interest thereon herein collectively called
"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 Notes (or their respective
         Predecessor Notes) are registered at the close of business on a
         special record date ("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 Note and the date of the proposed
         payment, and at the same time the Company shall deposit with the
         Trustee an amount of money equal to the aggregate amount proposed to
         be paid in respect of such Defaulted Interest or shall make
         arrangements satisfactory to the Trustee for such deposit prior to the
         date of the proposed payment, such money when deposited to be held in
         trust for the benefit of the Persons entitled to such Defaulted
         Interest as in this clause provided. Thereupon the Trustee shall fix a
         Special Record Date for the payment of such Defaulted Interest which
         shall be not more than 15 days and not less than 10 days prior to the
         date of the proposed payment and not less than 10 days after the
         receipt by the Trustee of the notice of the proposed payment. The
         Trustee shall promptly notify the Company of such Special Record Date
         and, in the name and at the expense of the Company, shall cause notice
         of the proposed payment of such Defaulted Interest and the Special
         Record Date therefor to be given in the manner provided for in Section
         106 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 given, such Defaulted Interest shall be
         paid to the Persons in whose names the Notes (or their respective
         Predecessor Notes) 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 Notes 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.

   37

                                                                              31


                  Subject to the foregoing provisions of this Section 307, each
Note delivered under this Indenture upon registration of transfer of or in
exchange for or in lieu of any other Note shall carry the rights to interest
accrued and unpaid, and to accrue, which were carried by such other Note.

SECTION 308. Persons Deemed Owners.

                  Prior to the due presentment of a Note 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 Note is registered as the owner of such
Note for the purpose of receiving payment of principal of (and premium, if any)
and (subject to Sections 305 and 307) interest on such Note and for all other
purposes whatsoever, whether or not such Note be overdue, and none of the
Company, the Trustee or any agent of the Company or the Trustee shall be
affected by notice to the contrary.

SECTION 309. Cancellation.

                  All Notes surrendered for payment, redemption, registration
of transfer or exchange shall, if surrendered to any Person other than the
Trustee, be delivered to, and promptly cancelled by, the Trustee. The Company
may at any time deliver to the Trustee for cancellation any Notes previously
authenticated and delivered hereunder which the Company may have acquired in
any manner whatsoever, and may deliver to the Trustee (or to any other Person
for delivery to the Trustee) for cancellation any Notes previously
authenticated hereunder which the Company has not issued and sold, and all
Notes so delivered shall be promptly cancelled by the Trustee. If the Company
shall so acquire any of the Notes, however, such acquisition shall not operate
as a redemption or satisfaction of the Indebtedness represented by such Notes
unless and until the same are surrendered to the Trustee for cancellation. No
Notes shall be authenticated in lieu of or in exchange for any Notes cancelled
as provided in this Section, except as expressly permitted by this Indenture.
All cancelled Notes held by the Trustee shall be disposed of by the Trustee in
accordance with its customary procedures and certification of their disposal
delivered to the Company unless by Company Order the Company shall direct that
cancelled Notes be returned to it after being appropriately designated as
cancelled.

SECTION 310. Computation of Interest.

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

SECTION 311. Book-Entry Provisions for Global Notes.

                  (a) Each Global Note initially shall (i) be registered in the
name of the Depositary for such Global Notes or the nominee of such Depositary,
(ii) be delivered to the Trustee as custodian for such Depositary and (iii)
bear legends as set forth in Section 202.

                  Except as provided in Section 311(b), owners of beneficial
interests in the Global Notes will not have Notes registered in their names,
will not receive physical delivery of Notes in

   38

                                                                              32


certificated form and will not be considered the registered owner or Holder
thereof under this Indenture for any purpose.

                  Members of, or Participants in, the Depositary shall have no
rights under this Indenture with respect to any Global Note, and the Depositary
may be treated by the Company, the Trustee and any agent of the Company or the
Trustee as the absolute owner of such Global Note for all purposes whatsoever.
Notwithstanding the foregoing, nothing herein shall prevent the Company, the
Trustee or any agent of the Company or the Trustee from giving effect to any
written certification, proxy or other authorization furnished by the Depositary
or impair, as between the Depositary and its Participants, the operation of
customary practices governing the exercise of the rights of a beneficial owner
of any Note. The registered Holder of a Global Note may grant proxies and
otherwise authorize any person, including Participants and persons that may
hold interests through Participants, to take any action which a Holder is
entitled to take under this Indenture or the Notes.

                  (b) Interests of beneficial owners in a Global Note may be
transferred in accordance with the applicable rules and procedures of the
Depositary. Transfers of a Global Note shall be limited to transfers of such
Global Note in whole, but not in part, to the Depositary, a nominee of the
Depositary, its successors or their respective nominees. Interests of
beneficial owners in the Global Notes may be transferred in accordance with the
rules and procedures of the Depositary. Notes in certificated form shall be
transferred to beneficial owners in exchange for their beneficial interests in
the Global Note, as the case may be, if (i) the Depositary (A) notifies the
Company that it is unwilling or unable to continue as depository for the Global
Notes and the Company thereupon fails to appoint a successor depository or (B)
has ceased to be a clearing agency registered under the Exchange Act; (ii)
there shall have occurred and be continuing an Event of Default with respect to
the Notes; or (iii) the Company, at its option, notifies the Trustee in writing
that it elects to cause issuance of the Notes in certificated form. In
connection with a transfer of an entire Global Note to beneficial owners
pursuant to clause (i), (ii) or (iii) of this paragraph (b), the applicable
Global Note shall be deemed to be surrendered to the Trustee for cancellation,
and the Company shall execute, and the Trustee shall authenticate and deliver,
to each beneficial owner identified by the Depositary in exchange for its
beneficial interest in the applicable Global Note, an equal aggregate principal
amount of certificated notes of authorized denominations.

                  destroyed, lost or stolen and which have been replaced or

                           within one year under arrangements satisfactory to

                           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
                  irrevocably deposited or caused to be deposited with the
                  Trustee as trust funds in trust for such purpose in an amount
                  sufficient to pay and discharge the entire Indebtedness on
                  such Notes 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 Notes
                  which have become due and payable) or to the Stated Maturity
                  or Redemption Date, as the case may be, together with
                  irrevocable instructions from the Company directing the
                  Trustee to apply such funds to the payment thereof at Stated
                  Maturity or redemption, 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
                  Officer's 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, the obligations of the Company to the Trustee under Section 606 and,
if money shall have been deposited with the Trustee pursuant to subclause (B)
of clause (1) of this Section, the obligations of the Trustee under Section 402
and the last paragraph of Section 1003 shall survive.

SECTION 402. Application of Trust Money

or through any Paying Agent (including the Company acting as its own Paying
Agent) as the Trustee may determine, to the Persons entitled thereto, of the
principal (and premium, if any) and interest for whose payment such money has
been deposited with the Trustee.

         all such final judgments or orders against all such Persons (treating
         any deductibles, self-insurance or retention as not so covered) shall
         be rendered against the Company or any Restricted Subsidiary and shall
         not be paid or discharged, and there shall be any period of 30
         consecutive days following entry of the final judgment or order that
         causes the aggregate amount for all such final judgments or orders
         outstanding and not paid or discharged against all such Persons to
         exceed $5 million during which a stay of enforcement of such final
         judgment or order, by reason of a pending appeal or otherwise, shall
         not be in effect; or

                  (9) a court having jurisdiction in the premises enters a
         decree or order for (A) relief in respect of the Company or any of its
         Significant Subsidiaries in an involuntary case under any applicable
         bankruptcy, insolvency or other similar law now or hereafter in
         effect, (B) appointment of a receiver, liquidator, assignee,
         custodian, trustee, sequestrator or similar official of the Company or
         any of its Significant Subsidiaries or for all or substantially all of
         the property and assets of the Company or any of its Significant
         Subsidiaries or (C) the winding up or liquidation of the affairs of
         the Company or any of its Significant Subsidiaries and, in each case,
         such decree or order shall remain unstayed and in effect for a period
         of 30 consecutive days; or

                  (10) the Company or any of its Significant Subsidiaries (A)
         commences a voluntary case under any applicable bankruptcy, insolvency
         or other similar law now or hereafter in effect, or consents to the
         entry of an order for relief in an involuntary case under any such
         law, (B) consents to the appointment of or taking possession by a
         receiver, liquidator, assignee, custodian, trustee, sequestrator or
         similar official of the Company or any of its Significant Subsidiaries
         or for all or substantially all of the property and assets of the
         Company or any of its Significant Subsidiaries or (C) effects any
         general assignment for the benefit of creditors; or

                  (11) the Company asserts in writing that the Pledge Agreement

         obligations thereunder.
   42

                                                                              36


SECTION 502. Acceleration of Maturity; Rescission and Annulment.

                  If an Event of Default (other than an Event of Default
specified in Section 501(9) or 501(10)) occurs and is continuing, then and in
every such case the Trustee or the Holders of not less than 25% in aggregate
principal amount of the Notes Outstanding by a notice in writing to the Company
(and to the Trustee if such notice given by such Holders), may, and the Trustee
at the request of such Holders shall, declare the principal of, premium, if
any, and accrued but unpaid interest on all the Notes to be immediately due and
payable. Upon any such declaration of acceleration, such principal of, premium,
if any, and accrued interest shall become immediately due and payable. If an
Event of Default specified in Section 501(9) or 501(10) occurs, then the
principal of, premium, if any, and accrued interest shall ipso facto become and
be immediately due and payable without any declaration or other act on the part
of the Trustee or any Holder.

                  At any time after a declaration of acceleration has been
made, the Holders of at least a majority in aggregate principal amount of the
Notes Outstanding, by written notice to the Company and the Trustee, may
rescind and annul such declaration and its consequences if:

                  (1) all existing Events of Default, other than the nonpayment
         of amounts of principal of, premium, if any, and accrued and unpaid
         interest on the Notes which have become due solely by such declaration
         of acceleration, have been cured or waived subject to the limitations
         set forth in Section 513; and

                  (2) the rescission, in the opinion of counsel, would not
         conflict with any judgment or decrees of a court of competent
         jurisdiction.

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

                  Notwithstanding the preceding paragraph, in the event of a
declaration of acceleration in respect of the Notes because an Event of Default
specified in Section 501(7) shall have occurred and be continuing, such
declaration of acceleration shall be automatically annulled if the Indebtedness
that is the subject of such Event of Default has been discharged or the Holders
thereof have rescinded their declaration of acceleration in respect of such
Indebtedness, and written notice of such discharge or rescission, as the case
may be, shall have been given to the Trustee by the Company and countersigned
by the Holders of such Indebtedness or a trustee, fiduciary or agent for such
Holders, within 60 days after such declaration of acceleration in respect of
the Notes, and no other Event of Default has occurred during such 60-day period
which has not been cured or waived during such period.

SECTION 503. Collection of Indebtedness and Suits for Enforcement by Trustee.

                  The Company covenants that if

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

   43

                                                                              37


                  (b) default is made in the payment of the principal of (or
         premium, if any, on) any Note at the Maturity thereof,

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

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

                  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 504. Trustee May File Proofs of Claim.

                  In case of the pendency of any receivership, insolvency,
liquidation, bankruptcy, reorganization, arrangement, adjustment, composition
or other judicial proceeding relative to the Company or any other obligor upon
the Notes or the property of the Company or of such other obligor or their
creditors, the Trustee (irrespective of whether the principal of the Notes
shall then be due and payable as therein expressed or by declaration or
otherwise and irrespective of whether the Trustee shall have made any demand on
the Company for the payment of overdue principal, premium, if any, or interest)
shall be entitled and empowered, by intervention in such proceeding or
otherwise,

                  (i) to file and prove a claim for the whole amount of
         principal (and premium, if any) and interest owing and unpaid in
         respect of the Notes and to file such other papers or documents and
         take other actions as the Trustee may deem necessary or advisable in
         order to have the claims of the Trustee (including any claim for the
         reasonable compensation, expenses, disbursements and advances of the
         Trustee, its agents and counsel) and of the Holders allowed in such
         judicial proceeding, and

                  (ii) 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
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

   44

                                                                              38


to the Holders, to pay 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 606.

                  Nothing herein contained shall be deemed to authorize the
Trustee to authorize or consent to or accept or adopt on behalf of any Holder
any plan of reorganization, arrangement, adjustment or composition affecting
the Notes 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.

SECTION 505. Trustee May Enforce Claims Without Possession of Notes.

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

SECTION 506. 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 Notes 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 606;

                  SECOND: To the payment of the amounts then due and unpaid for
         principal of (and premium, if any) and interest on the Notes 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 Notes for principal
         (and premium, if any) and interest, respectively; and

                  THIRD: The balance, if any, to the Person or Persons entitled
         thereto.

SECTION 507. Limitation on Suits.

                  Except to enforce the right to receive payment of principal
or premium, if any, or interest when due, no Holder of any Notes 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 the following conditions have been met:

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

                  (2) the Holders of not less than 25% in aggregate principal
         amount of the

   45

                                                                              39


         Outstanding Notes shall have made written request to the Trustee to
         pursue the remedy in respect of such Event of Default in its own name
         as trustee hereunder;

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

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

                  (5) during such 60-day period, no direction inconsistent with
         such written request has been given to the Trustee by the Holders of a
         majority or more in aggregate principal amount of the Outstanding
         Notes;

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 508. Unconditional Right of Holders to Receive Principal, Premium and
Interest.

                  Notwithstanding any other provision in this Indenture, the
Holder of any Note shall have the right, which is absolute and unconditional,
to receive payment, as provided herein (including, if applicable, Article
Thirteen) and in such Note of the principal of (and premium, if any) and
(subject to Section 307) interest on such Note on the respective Stated
Maturities expressed in such Note (or, in the case of redemption, on the
Redemption Date) and to institute suit for the enforcement of any such payment
on or after such Stated Maturities, and such rights shall not be impaired
without the consent of such Holder.

SECTION 509. 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.
   46

                                                                              40


SECTION 510. Rights and Remedies Cumulative.

                  Except as otherwise provided with respect to the replacement
or payment of mutilated, destroyed, lost or stolen Notes in the last paragraph
of Section 306, 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 511. Delay or Omission Not Waiver.

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

SECTION 512. Control by Holders.

                  The Holders of not less than a majority in aggregate
principal amount of the Outstanding Notes 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) the Trustee need not take any action that conflicts with
         law or this Indenture, which might involve the Trustee in personal
         liability or which, in the good faith determination of the Trustee,
         may be unduly prejudicial to rights Holders not joining in the giving
         of such direction, and

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

SECTION 513. Waiver of Past Defaults.

                  The Holders of not less than a majority in aggregate
principal amount of the Outstanding Notes may on behalf of the Holders of all
the Notes waive any past default hereunder and its consequences, except a
default

                  (1) in respect of the payment of the principal of (or
         premium, if any) or interest on any Note, or

                  (2) in respect of a covenant or provision hereof which under
         Article Nine cannot be modified or amended without the consent of the
         Holder of each Outstanding Note affected.
   47

                                                                              41


                  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 Event of Default or impair any right consequent
thereon.

SECTION 514. Waiver of Stay or Extension Laws.

                  The Company covenants (to the extent that it may lawfully do
so) that it shall not at any time insist upon, or plead, or in any manner
whatsoever claim or take the benefit or advantage of, any 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 shall not hinder, delay or impede the
execution of any power herein granted to the Trustee, but shall suffer and
permit the execution of every such power as though no such law had been
enacted.


                                  ARTICLE SIX

                                  THE TRUSTEE

SECTION 601. Notice of Defaults.

                  Within 90 days after the occurrence of any Default hereunder,
the Trustee shall transmit in the manner and to the extent provided in TIA
Section 313(c), notice of such Default hereunder of the Trustee, unless such
Default shall have been cured or waived; provided, however, that, except in the
case of a Default in the payment of the principal of (or premium, if any) or
interest on any Note, the Trustee shall be protected in withholding such notice
if and so long as the board of directors, the executive committee or a trust
committee of directors and/or Responsible Officers of the Trustee in good faith
determines that the withholding of such notice is in the interest of the
Holders; and provided further that in the case of any Default of the character
specified in Section 501(7), no such notice to Holders shall be given until at
least 30 days after the occurrence thereof.

                  In case an Event of Default has occurred and is continuing,
the Trustee shall exercise such of the rights and powers vested in it by this
Indenture, and use the same degree of care and skill in their exercise, as a
prudent person would exercise or use under the circumstances in the conduct of
his or her own affairs.

SECTION 602. Certain Rights of Trustee.

                  Subject to the provisions of TIA Sections 315(a) through
315(d):

         order, bond, debenture, note, other evidence of indebtedness or other
         paper or document believed by it to be genuine and to have been signed
         or presented by

   48

                                                                              42


         the proper party or parties;

                  (2) any request or direction of the Company mentioned herein

         and any resolution of the Board of Directors may be sufficiently
         evidenced by a Board Resolution;

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

                  (4) the Trustee may consult with counsel and the written
         advice of such counsel or any Opinion of Counsel shall be full and
         complete authorization and protection in respect of any action taken,
         suffered or omitted by it hereunder in good faith and in reliance
         thereon;

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

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

                  (7) the Trustee may execute any of the trusts or powers
         hereunder or perform any duties hereunder either directly or by or
         through agents or attorneys and the Trustee shall not be responsible
         for any misconduct or negligence on the part of any agent or attorney
         appointed with due care by it hereunder;

                  (8) the Trustee shall not be liable for any action taken,

         authorized or within the discretion or rights or powers conferred upon
         it by this Indenture;

                  (9) any permissive right or power available to the Trustee
         under this Indenture or any supplement hereto shall not be construed
         to be a mandatory duty or obligation;

                  (10) the Trustee shall not be charged with knowledge of any
         matter (including any default, other than as described in Section
         501(1), (2) or (3)) unless and except to the extent actually known to
         a Responsible Officer of the Trustee or to the extent written notice
         thereof is received by the Trustee at the Corporate Trust Office; and
   49

                                                                              43


                  (11) the Trustee shall have no liability for any inaccuracy
         in the books or records of, or for any actions or omissions of the
         Depositary.

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.

                  The Trustee shall not be required to examine any of the
reports and documents filed with it pursuant to Sections 703 or 1009 to
determine whether or not the Company is in compliance with the covenants set
forth at Sections 1010 through 1021.

SECTION 603. Trustee Not Responsible for Recitals or Issuance of Notes.

                  The recitals contained in this Indenture and in the Notes,
except for the Trustees certificates of authentication, shall be taken as the
statements of the Company, and the Trustee assumes no responsibility for their
correctness. The Trustee makes no representations as to the validity or
sufficiency of this Indenture or of the Notes, except that the Trustee
represents that it is duly authorized to execute and deliver this Indenture,
authenticate the Notes and perform its obligations hereunder and that the
statements made by it in a Statement of Eligibility on Form T-1 supplied to the
Company are true and accurate, subject to the qualifications set forth therein.
The Trustee shall not be accountable for the use or application by the Company
of Notes or the proceeds thereof.

SECTION 604. May Hold Notes.

                  The Trustee, any Paying Agent, any Registrar or any other
agent of the Company or of the Trustee, in its individual or any other
capacity, may become the owner or pledgee of Notes and, subject to TIA Sections
310(b) and 311, may otherwise deal with the Company with the same rights it
would have if it were not Trustee, Paying Agent, Registrar or such other agent.

SECTION 605. Money Held in Trust.

                  Money held by the Trustee in trust hereunder shall be
segregated from other funds. The Trustee shall be under no liability for
interest on any money received by it hereunder.

SECTION 606. Compensation and Reimbursement.

                  The Company agrees:

                  (1) to pay to the Trustee from time to time reasonable
         compensation for all services rendered by it hereunder and under the
         Pledge Agreement (which compensation shall not be limited by any
         provision of law in regard to the compensation of a trustee of an
         express trust);

                  (2) except as otherwise expressly provided herein, to
         reimburse the Trustee upon its request for all reasonable expenses,
         disbursements and advances incurred or made by

   50

                                                                              44


         the Trustee in accordance with any provision of this Indenture and
         under the Pledge Agreement (including the reasonable compensation and
         the expenses and disbursements of its agents and counsel), except any
         such expense, disbursement or advance as may be attributable to its
         negligence or bad faith; and

                  (3) to indemnify the Trustee for, and to hold it harmless
         against, any loss, liability or expense incurred without gross
         negligence or bad faith on its part, arising out of or in connection
         with the acceptance and administration of its duties under the Pledge
         Agreement or the acceptance or administration of this trust, including
         the costs and expenses of defending itself against any claim or
         liability in connection with the exercise or performance of any of its
         powers or duties hereunder.

                  The obligations of the Company under this Section to
compensate the Trustee, to pay or reimburse the Trustee for expenses,
disbursements and advances and to indemnify and hold harmless the Trustee shall
constitute additional indebtedness hereunder and shall survive the satisfaction
and discharge of this Indenture. As security for the performance of such
obligations of the Company, the Trustee shall have a claim prior to the Notes
upon all property and funds held or collected by the Trustee as such, except
funds held in trust for the payment of principal of (and premium, if any) or
interest on particular Notes.

                  When the Trustee incurs expenses or renders services in
connection with an Event of Default specified in Section 501(8) or (9), the
expenses (including the reasonable charges and expenses of its counsel) of and
the compensation for such services are intended to constitute expenses of
administration under any applicable federal or state bankruptcy, insolvency or
other similar law; provided, however, that if any such amounts are not paid as
expenses of administration, they may be collected by the Trustee as amounts
payable to it pursuant to Section 506.

                  The provisions of this Section 606 shall survive the
termination of this Indenture.

SECTION 607. Corporate Trustee Required; Eligibility.

                  There shall be at all times a Trustee hereunder which shall
be eligible to act as Trustee under TIA Section 310(a)(1) and shall have a
combined capital and surplus of at least $50 million. If such corporation
publishes reports of condition at least annually, pursuant to law or to the
requirements of federal, state, territorial or District of Columbia supervising
or examining authority, then for the purposes of this Section, the combined
capital and surplus of such corporation shall be deemed to be its combined
capital and surplus as set forth in its most recent report of condition so
published. If at any time the Trustee shall cease to be eligible in accordance
with the provisions of this Section 607, it shall resign immediately in the
manner and with the effect hereinafter specified in this Article.

SECTION 608. Resignation and Removal; Appointment of Successor.

                  (a) No resignation or removal of the Trustee and no

accordance with the applicable requirements of Section 609.
   51

                                                                              45


                  (b) The Trustee may resign at any time by giving written
notice thereof to the Company. If the instrument of acceptance by a successor
Trustee required by Section 609 shall not have been delivered to the Trustee
within 30 days after the giving of such notice of resignation, the resigning
Trustee may petition any court of competent jurisdiction for the appointment of
a successor Trustee.

                  (c) The Trustee may be removed at any time by Act of the
Holders of not less than a majority in aggregate principal amount of the
Outstanding Notes, delivered to the Trustee and to the Company.

                  (d) If at any time:

                           (1) the Trustee shall fail to comply with the
                  provisions of TIA Section 310(b) after written request
                  therefor by the Company or by any Holder who has been a bona
                  fide Holder of a Note for at least six months, or

                           (2) the Trustee shall cease to be eligible under
                  Section 607 and shall fail to resign after written request
                  therefor by the Company or by any Holder who has been a bona
                  fide Holder of a Note for at least six months, or

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

then, in any such case, (i) the Company, by a Board Resolution, may remove the
Trustee, or (ii) subject to TIA Section 315(e), any Holder who has been a bona
fide Holder of a Note for at least six months may, on behalf of himself and all
others similarly situated, petition any court of competent jurisdiction for the
removal of the Trustee and the appointment of a successor Trustee.

                  (e) If the Trustee shall resign, be removed or become
incapable of acting, or if a vacancy shall occur in the office of Trustee for
any cause, the Company, by a Board Resolution, shall promptly appoint a
successor Trustee. If, within one year after such resignation, removal or
incapability, or the occurrence of such vacancy, a successor Trustee shall be
appointed by Act of the Holders of a majority in aggregate principal amount of
the Outstanding Notes delivered to the Company and the retiring Trustee, the
successor Trustee so appointed shall, forthwith upon its acceptance of such
appointment, become the successor Trustee and supersede the successor Trustee
appointed by the Company. If no successor Trustee shall have been so appointed
by the Company or the Holders and accepted appointment in the manner
hereinafter provided, any Holder who has been a bona fide Holder of a Note 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.

                  (f) The Company shall give notice of each resignation and
each removal of the Trustee and each appointment of a successor Trustee to the
Holders in the manner provided for in Section 106. Each notice shall include
the name of the successor Trustee and the address of its Corporate Trust
Office.
   52

                                                                              46


SECTION 609. 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 610. Merger, Conversion, Consolidation or Succession to Business.

                  Any corporation into which the Trustee may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which the Trustee shall be a
party, or any corporation succeeding to all or substantially all of 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 Notes 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 Notes so authenticated with the
same effect as if such successor Trustee had itself authenticated such Notes.
In case at that time any of the Notes shall not have been authenticated, any
successor Trustee may authenticate such Notes either in the name of any
predecessor hereunder or in the name of the successor Trustee. In all such
cases such certificates shall have the full force and effect which this
Indenture provides for the certificate of authentication of the Trustee shall
have; provided, however, that the right to adopt the certificate of
authentication of any predecessor Trustee or to authenticate Notes in the name
of any predecessor Trustee shall apply only to its successor or successors by
merger, conversion or consolidation.

                                   COVENANTS

SECTION 1001.  Payment of Principal, Premium, if Any, and Interest.

             The Company covenants and agrees for the benefit of the Holders
that it shall duly and punctually pay the principal of (and premium, if any)
and interest on the Notes in accordance with the terms of the Notes and this
Indenture.

SECTION 1002.  Maintenance of Office or Agency.

             The Company shall maintain in The City of New York, an office or
agency where Notes may be surrendered for registration of transfer or exchange
and where notices and demands to or upon the Company in respect of the Notes
and this Indenture may be served. The office of the Trustee located at 40 Broad
Street, Suite 550, New York, New York 10004 shall be such office or agency of
the Company, unless the Company shall designate and maintain some other office
or agency for one or more of such purposes. In addition, the Company shall
maintain an office or agency where the Notes may be presented or surrendered
for payment (which shall be the Corporate Trust Office of the Trustee, unless
the Company shall designate and maintain some other office or agency for one or
more such purposes). The Company shall give prompt written notice to the
Trustee of any change in the location of any such office or agency. If at any
time the Company shall fail to maintain any such required office or agency or
shall fail to furnish the Trustee with the address thereof, such presentations,
surrenders, notices and demands may be made or served at the Corporate Trust
Office of the Trustee, and the Company hereby appoints the Trustee as its agent
to receive all such presentations, surrenders, notices and demands.

             The Company may also from time to time designate one or more other
offices or agencies where the Notes may be presented or surrendered for any or
all such purposes and may from time to time rescind any such designation;
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
City of New York for such purposes. The Company shall give prompt written
notice to the Trustee of any such designation or rescission and any change in
the location of any such other office or agency.

SECTION 1003.  Money for Note Payments to Be Held in Trust.

             If the Company shall at any time act as its own Paying Agent, it
shall, on or before each due date of the principal of (or premium, if any) or
interest on any of the Notes, segregate and hold in trust for the benefit of
the Persons entitled thereto a sum sufficient to pay the principal of (or
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 shall promptly
notify the Trustee of its action or failure so to act.

             Whenever the Company shall have one or more Paying Agents for the
Notes, it
   59

shall, on or before each due date of the principal of (or premium, if any) or
interest on any Notes, 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 in trust for the benefit of the Persons entitled to such principal,
premium or interest, and (unless such Paying Agent is the Trustee) the Company
shall promptly notify the Trustee of such action or any failure so to act.

             The Company shall 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 1003,
that such Paying Agent shall:

             (1) hold all sums held by it for the payment of the principal of
      (and premium, if any) or interest on Notes in trust for the benefit of
      the Persons entitled thereto until such sums shall be paid to such
      Persons or otherwise disposed of as herein provided;

             (2) give the Trustee notice of any default by the Company (or any
      other obligor upon the Notes) in the making of any payment of principal
      (and premium, if any) or interest on the Notes; and

             (3) at any time during the continuance of any such default, upon
      the written request of the Trustee, forthwith pay to the Trustee all sums
      so held in trust by such Paying Agent.

             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 terms 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 sums.

             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 (or premium,
if any) or interest on any Note and remaining unclaimed for two years after
such principal, premium 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 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;
provided, however, that the Trustee or such Paying Agent, before being required
to make any such repayment, may at the expense of the Company cause to be
published once, in a newspaper published in the English language, customarily
published on each Business Day and of general circulation in the Borough of
Manhattan, The City of New York, notice that such money remains unclaimed and
that, after a date specified therein, which shall not be less than 30 days from
the date of such publication, any unclaimed balance of such money then
remaining shall be repaid to the Company.

SECTION 1004.  Corporate Existence.

             Subject to Article Eight, the Company shall do or cause to be done
all things necessary to preserve and keep in full force and effect the
corporate existence (or in the case of

   60

its Subsidiaries, existence under the applicable statutes for non-corporate
business entities such as partnerships and limited liability companies), rights
(charter and statutory) and franchises of the Company and each Subsidiary;
provided, however, that the Company shall not be required to preserve any such
right or franchise if the Board of Directors shall determine that the
preservation thereof is no longer desirable in the conduct of the business of
the Company and its Subsidiaries as a whole and that the loss thereof is not
disadvantageous in any material respect to the Holders.

SECTION 1005.  Payment of Taxes and Other Claims.

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

SECTION 1006.  Maintenance of Properties.

             The Company shall cause all properties owned by the Company or any
Subsidiary or used or held for use in the conduct of its business or the
business of any Subsidiary to be maintained and kept in good condition, repair
and working order and supplied with all necessary equipment and shall 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 maintenance of any of
such properties if such discontinuance is, in the judgment of the Company,
desirable in the conduct of its business or the business of any Subsidiary and
not disadvantageous in any material respect to the Holders.

SECTION 1007.  Insurance.

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

SECTION 1008.  Statement by Officers as to Default.

             (a) The Company shall deliver to the Trustee, within 120 days
after the end of each fiscal year, an Officer's Certificate from the principal

fulfilled its obligations thereunder or, if there has been a default in the
fulfillment of any such obligation, specifying each such default and the nature
and status thereof. For purposes of this Section 1008(a), such compliance shall
be determined without regard to any

   61

period of grace or requirement of notice under this Indenture.

             (b) When any Default has occurred and is continuing under this
Indenture, or if the trustee for or the Holder of any other evidence of

Indebtedness in the principal amount of less than $1,000,000) shall deliver to

Section 1011, in the event that an item of Indebtedness meets the criteria of
more than one of the types of Indebtedness described in the above clauses, the
Company, in its sole discretion may, at the time of such Incurrence, (i)
classify such item of Indebtedness under and comply with either of paragraph

             (A) a Default or Event of Default shall have occurred and be
      continuing;

             (B) the Company could not Incur at least $1.00 of Indebtedness
      under paragraph (a) of Section 1011; and

             (C) the aggregate amount of all Restricted Payments declared or
      made from and after the Exchange Date would exceed the sum of:

      to a Person, which is not a Subsidiary of the Company, of Capital Stock
      of the Company (other than Redeemable Stock) or of debt securities of the
      Company which have been converted into or exchanged for such Capital
      Stock (except to the extent such Net Cash Proceeds are used to Incur new
      Indebtedness outstanding pursuant to clause (viii) of paragraph (b) of
      Section 1011); and

             (3) to the extent any Permitted Investment that was made after the
      Exchange Date is sold for cash or otherwise liquidated or repaid for
      cash, the lesser of (i) the cash return of capital with respect to such
      Permitted Investment (less the cost of disposition, if any) and (ii) the
      initial amount of such Permitted Investment.

             The foregoing provision shall not be violated by reason of: (i)
the payment of any dividend within 60 days after the date of declaration
thereof if, at said date of declaration, such payment would comply with the
foregoing paragraph; (ii) the redemption, repurchase, defeasance or other
acquisition or retirement for value of Indebtedness that is subordinated in

in the event that The 1818 Fund III, L.P. ("The 1818 Fund") exercises its
option to purchase up to 20,000 additional shares of Senior Preferred Stock,
then such additional shares as well and (B) 23,174 outstanding shares of 4.25%
Cumulative Junior Convertible Preferred Stock, Series B, par value $0.01 per
share (the "Junior Preferred Stock"); (vii) the conversion of the Senior

or payments set forth therein.
   68

             Each Restricted Payment permitted pursuant to the immediately
preceding paragraph (other than the Restricted Payment referred to in clause
(ii) thereof) and the Net Cash Proceeds from any capital contributions to the
Company or issuance of Capital Stock referred to in clauses (iii) and (iv) of
the immediately preceding paragraph, shall be included in calculating whether
the conditions of clause (C) of the first paragraph of this Section 1012 have
been met with respect to any subsequent Restricted Payments. In the event the
proceeds of an issuance of Capital Stock of the Company are used for the
redemption, repurchase or other acquisition of the Notes, then the Net Cash
Proceeds of such issuance shall be included in clause (C) of the first
paragraph of this Section 1012 only to the extent such proceeds are not used
for such redemption, repurchase or other acquisition of the Notes.

SECTION 1013. Limitation on Dividend and Other Payment Restrictions Affecting
              Restricted Subsidiaries.

             So long as any of the Notes are Outstanding, the Company shall
not, and shall not permit any Restricted Subsidiary to, create or otherwise
cause or suffer to exist or become effective any consensual encumbrance or
restriction of any kind on the ability of any Restricted Subsidiary to do any
one of the following:

             (i) pay dividends or make any other distributions permitted by
      applicable law on any Capital Stock of such Restricted Subsidiary owned
      by the Company or any other Restricted Subsidiary;

             (ii) pay any Indebtedness owed to the Company or any other
      Restricted Subsidiary;

             (iii) make loans or advances to the Company or any other
      Restricted Subsidiary; or

             (iv) transfer any of its property or assets (including the Capital
      Stock of any Restricted Subsidiary) to the Company or any other
      Restricted Subsidiary.

             The foregoing provisions shall not restrict any encumbrances or
restrictions:

             (i) existing on the Exchange Date in this Indenture or any other
      agreements or instruments in effect on the Exchange Date, and any
      extensions, refinancings, renewals or replacements of such agreements;
      provided that the encumbrances and restrictions in any such extensions,
      refinancings, renewals or replacements are no less favorable in any
      material respect to the Holders than those encumbrances or restrictions
      that are then in effect and that are being extended, refinanced, renewed
      or replaced;

             (ii) contained in the terms of any Indebtedness or any agreement
      pursuant to which such Indebtedness was issued if the encumbrance or
      restriction applies only in the event of a default with respect to a
      financial covenant contained in such Indebtedness or agreement and such
      encumbrance or restriction is not materially, more disadvantageous to the
      Holders than is customary in comparable financing (as determined by the
      Company) and the Company determines that any such encumbrance or
      restriction will not
   69


      materially affect the Company's ability to make principal or interest
      payments on the Notes;

             (iii) existing under or by reason of applicable law;

             (iv) existing with respect to any Person or the property or assets
      of such Person acquired by the Company or any Restricted Subsidiary,
      existing at the time of such acquisition and not incurred in
      contemplation thereof, which encumbrances or restrictions are not
      applicable to any Person or the property or assets of any Person other
      than such Person or the property or assets of such Person so acquired;

             (v) in the case of clause (iv) of the first paragraph of this
      Section 1013, (A) that restrict in a customary manner the subletting,
      assignment or transfer of any property or asset that is, or is subject
      to, a lease, purchase mortgage obligation, license, conveyance or
      contract or similar property or asset, (B) existing by virtue of any
      transfer of, agreement to transfer, option or right with respect to, or
      Lien on, any property or assets of the Company or any Restricted
      Subsidiary not otherwise prohibited by this Indenture or (C) arising or
      agreed to in the ordinary course of business, not relating to any
      Indebtedness, and that do not, individually or in the aggregate, detract
      from the value of property or assets of the Company or any Restricted
      Subsidiary in any manner material to the Company or any Restricted
      Subsidiary; or

             (vi) with respect to a Restricted Subsidiary and imposed pursuant
      to an agreement that has been entered into for the sale or disposition of
      all or substantially all of the Capital Stock of, or property and assets
      of, such Restricted Subsidiary. Nothing contained in this Section 1013
      shall prevent the Company or any Restricted Subsidiary from (1) creating,
      incurring, assuming or suffering to exist any Liens otherwise permitted
      in Section 1016 or (2) restricting the sale or other disposition of
      property or assets of the Company or any of its Restricted Subsidiaries
      that secure Indebtedness of the Company or any of its Restricted
      Subsidiaries.

SECTION 1014. Limitation on the Issuance and Sale of Capital Stock of
              Restricted Subsidiaries.

             The Company shall not, and shall not permit any Restricted
Subsidiary, directly or indirectly, to issue, transfer, distribute, convey,
sell, lease or otherwise dispose of any shares of Capital Stock (including
options, warrants or other rights to purchase shares of such Capital Stock) of
such or any other Restricted Subsidiary (other than to the Company or a Wholly
Owned Restricted Subsidiary or in respect of any director's qualifying shares
or sales of shares of Capital Stock to foreign nationals mandated by applicable
law or pursuant to the exercise of employee or non-employee options to purchase
the Capital Stock of the Company) to any Person unless (A) the Net Cash
Proceeds from such issuance, transfer, conveyance, sale, lease or other
disposition are applied in accordance with Section 1017, (B) immediately after
giving effect to such issuance, transfer, conveyance, sale, lease or other
disposition, such Restricted Subsidiary would no longer constitute a Restricted
Subsidiary and (C) any Investment in such Person remaining after giving effect
to such issuance, transfer, conveyance, sale, lease or other disposition would
have been permitted to be made under Section 1012 if made on the date of such
issuance, transfer, conveyance, sale, lease or other disposition (valued as
provided in the
   70


definition of "Investment" contained in Section 101).

SECTION 1015.  Limitation on Transactions with Stockholders and Affiliates.

             The Company shall not, and shall not permit any Restricted
Subsidiary to, directly or indirectly, enter into, renew or extend any
transaction (including, without limitation, the purchase, sale, lease or
exchange of property or assets, or the rendering of any service) with any
holder (or any Affiliate of such holder) of 5% or more of any class of Capital
Stock of the Company or any Restricted Subsidiary or with any Affiliate of the
Company or any Restricted Subsidiary, unless the following conditions have been
met:

             (i) such transaction or series of transactions is on terms no less
      favorable to the Company or such Restricted Subsidiary than those that
      could be obtained in a comparable arm's-length transaction with a Person
      that is not such a holder or an Affiliate;

             (ii) if such transaction or series of transactions involves
      aggregate consideration in excess of $2 million, then such transaction or
      series of transactions is approved by a majority of the Board of
      Directors of the Company and is evidenced by a resolution therein; and

             (iii) if such transaction or series of transactions involves
      aggregate consideration in excess of $10 million, then the Company or
      such Restricted Subsidiary shall deliver to the Trustee a written opinion
      as to the fairness to the Company or such Restricted Subsidiary of such
      transaction from a financial point of view from a nationally recognized
      investment banking firm (or, if an investment banking firm is generally
      not qualified to give such an opinion, by a nationally recognized
      appraisal firm or accounting firm).

             The foregoing limitation does not limit, and will not apply to (i)
any transaction between the Company and any of its Restricted Subsidiaries or
between Restricted Subsidiaries; (ii) the payment of reasonable and customary
regular fees to directors of the Company who are not employees of the Company;
(iii) any Restricted Payments not prohibited by Section 1012; (iv) loans and
advances to officers or employees of the Company and its Subsidiaries not
exceeding at any one time outstanding $1.5 million in the aggregate, made in the
ordinary course of business; (v) arrangements with TMG, Armstrong and/or its
subsidiaries existing on the date of the Original Indenture and listed on
Schedule A attached thereto as such arrangements may be extended or renewed;
provided that the terms of any arrangement altered by any such extension or
renewal may not be altered in a manner adverse to the Company or the Holders of
the Notes; (vi) the issuance of up to 20,000 additional shares of Senior
Preferred Stock to The 1818 Fund pursuant to an option agreement existing on the
date of this Indenture; (vii) the sale to and purchase by the Company from MCI
WorldCom, Inc. and its Affiliates of telecommunications services and equipment
in the ordinary course of business; (viii) the issuance and sale by the Company
of Common Stock whether pursuant to the conversion of the Senior Preferred
Stock, the Junior Preferred Stock, the Company"s Convertible Preferred Stock,
Series C, par value $0.01 per share, or any other class or series of Preferred
Stock into Capital Stock of the Company, the exercise of any employee or
non-employee options to purchase the Capital Stock of the Company; and (ix) the
Company"s and any of its Restricted Subsidiaries" arrangements with the World
Access Charitable Trust listed on
   71

Schedule A attached hereto as such arrangements exist on the Exchange Date and
as such arrangements may be amended; provided that the terms of any such
amendments are not materially adverse to the Company, any Restricted Subsidiary
or the Holders of the Notes.

SECTION 1016.  Limitation on Liens.

             The Company shall not, and shall not permit any Restricted
Subsidiary to, directly or indirectly, create, incur, assume or suffer to exist
any Lien (other than Permitted Liens) on any of its assets or properties of any
character (including, without limitation, licenses and trademarks), or any
shares of Capital Stock or Indebtedness of any Restricted Subsidiary, whether
owned at the date of this Indenture or thereafter acquired, or any income,
profits or proceeds therefrom, or assign or otherwise convey any right to
receive income thereof, without making effective provision for all of the Notes
and all other amounts ranking pari passu with the Notes to be directly secured
equally and ratably with the obligation or liability secured by such Lien or,
if such obligation or liability is subordinated to the Notes and other amounts
ranking pari passu with the Notes, without making provision for the Notes and
such other amounts to be directly secured prior to the obligation or liability
secured by such Lien.

SECTION 1017.  Limitation on Asset Sales.

             The Company shall not, and shall not permit any Restricted
Subsidiary to, make any Asset Sale unless (i) the Company or the Restricted
Subsidiary, as the case may be, receives consideration at the time of such sale
or other disposition at least equal to the Fair Market Value of the assets sold
or disposed of as determined by the good faith judgment of the Board of
Directors evidenced by a Board Resolution and (ii) at least 80% of the
consideration received for such sale or other disposition consists of cash or
cash equivalents or the assumption of unsubordinated Indebtedness; provided
that any securities, notes or other obligations issued by an Investment Grade
Company with a Total Equity Market Capitalization in excess of $25 billion
determined at the time any commitment to effect any such Asset Sale is entered
into which are received by the Company or the Restricted Subsidiary, as the
case may be, and are converted within 180 days thereof into cash or cash
equivalents shall be deemed to be cash or cash equivalents; provided further
that the amount of cash or cash equivalents realized upon the sale of any such
securities, notes or other obligations must be included within the amount of
Net Cash Proceeds for purposes of clause (i)(B) of the next paragraph.

             The Company shall, or shall cause the relevant Restricted
Subsidiary to, within 270 days after the date of receipt of the Net Cash
Proceeds from an Asset Sale, (i) (A) apply an amount equal to such Net Cash
Proceeds to permanently repay unsubordinated Indebtedness of the Company or
Indebtedness of any Restricted Subsidiary, in each case owing to a Person other
than the Company or any of its Restricted Subsidiaries, or (B) if the Net Cash
Proceeds from such Asset Sale exceed $15 million, apply an amount equal to such
Net Cash Proceeds to make an offer to purchase (an "Offer to Purchase") from
the Holders on a pro rata basis an aggregate principal amount of Notes equal to
such Net Cash Proceeds, at a purchase price equal to 100% of the principal
amount of the Notes, plus, in each case, accrued and unpaid interest to the
date of purchase and less the product of (a) the Market Value per share of the
Common Stock of the Company and (b) the number of shares (including any portion
of a share) of such Common Stock determined by dividing $50 by the Market Price
of the Common Stock for each $1,000 in principal amount of Notes accepted for
purchase by the Company (the "Offer to Purchase
   72

Payment"), provided that the Company shall not be obligated to make any Offer
to Purchase after it has made one or more Offers to Purchase, which Offer or
Offers to Purchase, in the aggregate, were for an aggregate principal amount of
Notes equal to the aggregate principal amount of Notes issued on the Exchange
Date (regardless of the actual aggregate principal amount of Notes actually
tendered in such Offer or Offers to Purchase), or (C) if the Company has made
sufficient Offers to Purchase such that it has satisfied its obligation as
described in the final proviso to clause (B), invest an equal amount, or the
amount not so applied pursuant to clause (A), in property or assets of a nature
or type or that are used in a business (or in a company having property and
assets of a nature or type, or engaged in a business) similar or related to the
nature or type of the property and assets of, or the business of, the Company
and its Restricted Subsidiaries existing on the date of such investment (as
determined in good faith by the Board of Directors, whose determination shall
be conclusive and evidenced by a Board Resolution) and (ii) apply (no later
than the end of the 270-day period referred to above) such excess Net Cash
Proceeds (to the extent not applied pursuant to clause (i)) as provided in the
following paragraphs of this Section 1017. The amount of such Net Cash Proceeds
required to be applied (or to be committed to be applied) during such 270-day
period referred to above in the preceding sentence and not applied as so
required by the end of such period shall constitute "Excess Proceeds".

             If, as of the first day of any calendar month, the aggregate
amount of Excess Proceeds not theretofore subject to an Excess Proceeds Offer
(as defined below) totals at least $10 million, the Company must, not later
than the 30th Business Day thereafter, make an offer (an "Excess Proceeds
Offer") to purchase from the Holders on a pro rata basis an aggregate principal
amount of Notes equal to the Excess Proceeds on such date, at a purchase price
equal to 100% of the principal amount of the Notes, plus, in each case, accrued
and unpaid interest to the date of purchase less the product of (a) the Market
Value per share of the Common Stock of the Company and (b) the number of shares
(including any portion of a share) of such Common Stock determined by dividing
$50 by the Market Price of the Common Stock for each $1,000 in principal amount
of Notes accepted for purchase by the Company (the "Excess Proceeds Payment").

             The Company shall commence an Offer to Purchase or an Excess
Proceeds Offer by mailing a notice to the Trustee and each Holder stating: (i)
that the Offer to Purchase or Excess Proceeds Offer, as applicable, is being
made pursuant to this Section 1017 and that all Notes validly tendered will be
accepted for payment on a pro rata basis; (ii) the purchase price and the date
of purchase (which shall be a Business Day no earlier than 30 days nor later
than 60 days from the date such notice is mailed) (the "Offer Payment Date");
(iii) that any Note not tendered will continue to accrue interest pursuant to
its terms; (iv) that, unless the Company defaults in the payment of the Offer
to Purchase Payment or the Excess Proceeds Payment, as applicable, any Note
accepted for payment pursuant to the Offer to Purchase or the Excess Proceeds
Offer, as applicable, shall cease to accrue interest on and after the
applicable Offer Payment Date; (v) that Holders electing to have a Note
purchased pursuant to the Offer to Purchase or the Excess Proceeds Offer, as
applicable, will be required to surrender the Note, together with the form
entitled "Option of the Holder to Elect Purchase" on the reverse side of the
Note completed, to the Paying Agent at the address specified in the notice
prior to the close of business on the Business Day immediately preceding the
applicable Offer Payment Date; (vi) that Holders shall be entitled to withdraw
their election if the Paying Agent receives, not later than the close of
business on the third Business Day immediately preceding the applicable Offer
Payment Date, a telegram, facsimile transmission or letter setting forth the
name of such Holder,
   73

the principal amount of Notes delivered for purchase and a statement that such
Holder is withdrawing his election to have such Notes purchased; and (vii) that
Holders whose Notes are being purchased only in part will be issued new Notes
equal in principal amount to the unpurchased portion of the Notes surrendered;
provided that each Note purchased and each new Note issued shall be in a
principal amount of $1,000 or integral multiples thereof.

             On the applicable Offer Payment Date, the Company shall (i) accept
for payment on a pro rata basis Notes or portions thereof tendered pursuant to
the Offer to Purchase or the Excess Proceeds Offer, as applicable; (ii) deposit
with the Paying Agent money sufficient to pay the purchase price of all Notes
or portions thereof so accepted; and (iii) deliver, or cause to be delivered,
to the Trustee all Notes or portions thereof so accepted together with an
Officer's Certificate specifying the Notes or portions thereof accepted for
payment by the Company. The Paying Agent shall promptly mail to the Holders of
Notes so accepted payment in an amount equal to the purchase price, and the
Trustee shall upon Company Order promptly authenticate and mail to such Holders
a new Note equal in principal amount to any unpurchased portion of the Note
surrendered; provided that each Note purchased and each new Note issued shall
be in a principal amount of $1,000 or integral multiples thereof. With respect
to any Excess Proceeds Offer, to the extent that the aggregate principal amount
of Notes tendered is less than the Excess Proceeds, the Company may use any
remaining Excess Proceeds for general corporate purposes. The Company shall
publicly announce the results of the Excess Proceeds Offer as soon as
practicable after the Offer Payment Date. For purposes of this Section 1017,
the Trustee shall act as the Paying Agent.

             The Company shall comply with Rule 14e-1 under the Exchange Act
and any other securities laws and regulations thereunder to the extent such
laws and regulations are applicable, in the event that the Company undertakes
an Offer to Purchase or Excess Proceeds Offer under this Section 1017.

SECTION 1018. Limitation on Issuances of Guarantees of Indebtedness by
              Restricted Subsidiaries.

             The Company shall not permit any Restricted Subsidiary, directly
or indirectly, to Guarantee, assume or in any other manner become liable with
respect to any Indebtedness of the Company, other than Indebtedness under
Credit Facilities incurred under clause (iii) of paragraph (b) in Section 1011,
unless (i) such Restricted Subsidiary simultaneously executes and delivers a
supplemental indenture to this Indenture providing for a Guarantee of the Notes
on terms substantially similar to the Guarantee of such Indebtedness, except
that if such Indebtedness is by its express terms subordinated in right of
payment to the Notes, any such assumption, Guarantee or other liability of such
Restricted Subsidiary with respect to such Indebtedness shall be subordinated
in right of payment to such Restricted Subsidiary's assumption, Guarantee or
other liability with respect to the Notes substantially to the same extent as
such Indebtedness is subordinated to the Notes and (ii) such Restricted
Subsidiary waives, and shall not in any manner whatsoever claim or take the
benefit or advantage of, any rights of reimbursement, indemnity or subrogation
or any other rights against the Company or any other Restricted Subsidiary as a
result of any payment by such Restricted Subsidiary under its Guarantee.

             Notwithstanding the foregoing, any Guarantee by a Restricted
Subsidiary may provide by its terms that it will be automatically and
unconditionally released and discharged
   74

upon (i) any sale, exchange or transfer, to any Person not an Affiliate of the
Company, of all of the Company's and each Restricted Subsidiary's Capital Stock
in, or all or substantially all of the assets of, such Restricted Subsidiary
(which sale, exchange or transfer is not prohibited by this Indenture) or (ii)
the release or discharge of the guarantee which resulted in the creation of
such Guarantee, except a discharge or release by or as a result of payment
under such Guarantee.

SECTION 1019. Business of the Company; Restriction on Transfers of Existing
              Business.

             The Company shall not, and shall not permit any Restricted
Subsidiary to, be principally engaged in any business or activity other than a
Permitted Business. In addition, the Company and any Restricted Subsidiary
shall not be permitted to, directly or indirectly, transfer to any Unrestricted
Subsidiary (i) any of the licenses, material agreements or instruments, permits
or authorizations used in the Permitted Business of the Company and any
Restricted Subsidiary on the Exchange Date or (ii) any material portion of the
"property and equipment" (as such term is used in the Company's consolidated
financial statements) of the Company or any Restricted Subsidiary used in the
licensed service areas of the Company and any Restricted Subsidiary as they
exist on the Exchange Date.

SECTION 1020. Limitation on Investments in Unrestricted Subsidiaries.

             The Company shall not make, and shall not permit any of its
Restricted Subsidiaries to make, any Investments in Unrestricted Subsidiaries
if, at the time thereof, the aggregate amount of such Investments together with
any other Restricted Payments made after the Exchange Date would exceed the
amount of Restricted Payments then permitted to be made pursuant to Section
1012. Any Investments in Unrestricted Subsidiaries permitted to be made
pursuant to this covenant (i) shall be treated as the making of a Restricted
Payment in calculating the amount of Restricted Payments made by the Company or
a Subsidiary and (ii) may be made in cash or property (if made in property, the
Fair Market Value thereof as determined by the Board of Directors of the
Company (whose determination shall be conclusive and evidenced by a Board
Resolution) shall be deemed to be the amount of such Investment for the purpose
of clause (i) of this Section 1020).


SECTION 1021. Limitation on Sale-Leaseback Transactions.

             The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, enter into any Sale-Leaseback Transaction with respect to any
property of the Company or any of its Restricted Subsidiaries.

             Notwithstanding the foregoing, the Company may enter into
Sale-Leaseback Transactions; provided, however, that (a) the Attributable Value
of such Sale-Leaseback Transaction shall be deemed to be Indebtedness of the
Company and (b) after giving pro forma effect to any such Sale-Leaseback
Transaction and the foregoing clause (a), other than any Sale-Leaseback
Transaction involving NACT Telecommunications, Inc."s facility in Provo, Utah,
the Company would be able to incur $1.00 of additional Indebtedness (other than
Permitted Indebtedness) pursuant to Section 1011.

SECTION 1022. Waiver of Certain Covenants.
   75

             The Company may omit in any particular instance to comply with any
term, provision or condition set forth in Section 803 or Sections 1007 through
1021, inclusive, if before or after the time for such compliance the Holders of
at least a majority in aggregate principal amount of the Outstanding Notes, by
Act of such Holders, waive such compliance in such instance with such term,
provision or condition, but no such waiver shall extend to or affect such term,
provision 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 term, provision or condition shall
remain in full force and effect.

             (b) Notwithstanding the foregoing, prior to January 15, 2001, the
Company may redeem up to 35% of the originally issued aggregate principal
amount of the Notes on one or more occasions with the Net Cash Proceeds of one
or more Public Equity Offerings at a redemption price equal to 110.5% of the
aggregate principal amount thereof, plus accrued interest, if any, thereon to
the Redemption Date (subject to the right of Holders of record on the relevant
Regular Record Date to receive interest due on an Interest Payment Date);
provided that, immediately after giving effect to such redemption, at least 65%
of the originally issued aggregate principal amount of the Notes remains
Outstanding; and provided further that notice of such redemptions shall be
given within 60 days of the date of closing of any such Public Equity Offering.

SECTION 1102.  Applicability of Article.

             Redemption of Notes at the election of the Company or otherwise,
as permitted or required by any provision of this Indenture, shall be made in
accordance with such provision and this Article.

SECTION 1103.  Election to Redeem; Notice to Trustee.

             The election of the Company to redeem any Notes pursuant to
Section 1101 shall be evidenced by a Board Resolution. In case of any
redemption at the election of the Company, the Company shall, at least 60 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 Redemption Price and of the principal amount of Notes to be
redeemed and shall deliver to the Trustee such documentation and records as
shall enable the Trustee to select the Notes to be redeemed pursuant to Section
1104.
   76

SECTION 1104.  Selection by Trustee of Notes to Be Redeemed.

             If less than all the Notes are to be redeemed, the particular
Notes to be redeemed shall be selected not more than 60 days prior to the
Redemption Date by the Trustee, from the Outstanding Notes not previously
called for redemption, in compliance with the requirements of the principal
national securities exchange, if any, on which the Notes are listed or, if the
Notes are not listed on a national securities exchange, on a pro rata basis;
provided, however, that no such partial redemption shall reduce the portion of
the principal amount of a Note not redeemed to less than $1,000.

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

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

SECTION 1105.  Notice of Redemption.

             Notice of redemption shall be given in the manner provided for in
Section 106 not less than 30 nor more than 60 days prior to the Redemption
Date, to each Holder of Notes to be redeemed.

             All notices of redemption shall state:

             (1) the Redemption Date;

             (2) the Redemption Price and the amount of accrued interest to the
      Redemption Date payable as provided in Section 1107, if any;

             (3) if less than all Outstanding Notes are to be redeemed, the
      identification (and, in the case of a partial redemption, the principal
      amounts) of the particular Notes to be redeemed;

             (4) in case any Note is to be redeemed in part only, the notice
      which relates to such Note shall state that on and after the Redemption
      Date, upon surrender of such Note, the Holder shall receive, without
      charge, a new Note or Notes of authorized denominations for the principal
      amount thereof remaining unredeemed;

             (5) that on the Redemption Date the Redemption Price (and accrued
      interest, if any, to the Redemption Date payable as provided in Section
      1107) will become due and payable upon each such Note, or the portion
      thereof, to be redeemed, and that interest thereon will cease to accrue
      on and after said date; and

             (6) the place or places where such Notes are to be surrendered for
      payment of the Redemption Price and accrued interest, if any.
   77

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

SECTION 1106.  Deposit of Redemption Price.

             Prior to 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 1003) an amount of
money sufficient to pay the Redemption Price of, and accrued interest on, all
the Notes which are to be redeemed on that date.

SECTION 1107. Notes Payable on Redemption Date.

             Notice of redemption having been given as aforesaid, the Notes so
to be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified (together with accrued interest, if any, to
the Redemption Date), and from and after such date (unless the Company shall
default in the payment of the Redemption Price and accrued interest) such Notes
shall cease to bear interest. Upon surrender of any such Note for redemption in
accordance with said notice, such Note shall be paid by the Company at the
Redemption Price, together with accrued interest, if any, 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
Notes, or one or more Predecessor Notes, registered as such at the close of
business on the relevant Regular Record Dates according to their terms and the
provisions of Section 307.

             If any Note called for redemption 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 borne by the
Notes.

SECTION 1108. Notes Redeemed in Part.

             Any Note which is to be redeemed only in part (pursuant to the
provisions of this Article Eleven) shall be surrendered at the office or agency
of the Company maintained for such purpose pursuant to Section 1002 (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 such Holder's attorney duly authorized in
writing), and the Company shall execute, and the Trustee shall upon Company
Order authenticate and deliver to the Holder of such Note without service
charge, a new Note or Notes, of any authorized denomination as requested by
such Holder, in aggregate principal amount equal to and in exchange for the
unredeemed portion of the principal of the Note so surrendered.

                                                                             72


                                 ARTICLE TWELVE

                                    SECURITY

SECTION 1201.      Security.

                  (a) On the Exchange Date, the pro rata portion of the total
amount of the FaciliCom Pledged Securities based on the percentage of the
aggregate principal amount of the FaciliCom Notes exchanged for Notes shall be
released from the FaciliCom Pledge Account and deposited in the Pledge Account
by the Company to be held pursuant to the Pledge Agreement. The Pledged
Securities shall be pledged by the Company to the Trustee for the benefit of
the Holders and shall be held by the Trustee in the Pledge Account pending
disposition pursuant to the Pledge Agreement.

                  (b) Each Holder, by its acceptance of a Note, consents and
agrees to the terms of the Pledge Agreement (including, without limitation, the
provisions providing for foreclosure and release of the Pledged Securities) as
the same may be in effect or may be amended from time to time in accordance
with its terms, and authorizes and directs the Trustee to enter into the Pledge
Agreement and to perform its respective obligations and exercise its respective
rights thereunder in accordance therewith. The Company shall do or cause to be
done all such acts and things as may be necessary or proper, or as may be
required by the provisions of the Pledge Agreement, to assure and confirm to
the Trustee the security interest in the Pledged Securities contemplated
hereby, by the Pledge Agreement or any part thereof, as from time to time
constituted, so as to render the same available for the security and benefit of
this Indenture and of the Notes secured hereby, according to the intent and
purposes herein expressed. The Company shall take, or shall cause to be taken,
any and all actions reasonably required (and any action reasonably requested by
the Trustee) to cause the Pledge Agreement to create and maintain, as security
for the obligations of the Company under this Indenture and the Notes, valid
and enforceable first priority liens in and on all the Pledged Securities, in
favor of the Trustee, superior to and prior to the rights of third Persons and
subject to no other Liens.

                  (c) The release of any Pledged Securities pursuant to the
Pledge Agreement will not be deemed to impair the security under this Indenture
in contravention of the provisions hereof if and to the extent the Pledged
Securities are released pursuant to this Indenture and the Pledge Agreement. To
the extent applicable, the Company shall cause TIA Section 314(d) relating to
the release of property or securities from the Lien and security interest of
the Pledge Agreement (other than pursuant to Sections 7(e) and 7(g) thereof)
and relating to the substitution therefor of any property or securities to be
subjected to the Lien and security interest of the Pledge Agreement to be
complied with. Any certificate or opinion required by TIA Section 314(d) may be
made by an officer of the Company, except in cases where TIA Section 314(d)
requires that such certificate or opinion be made by an independent Person,
which Person shall be an independent engineer, appraiser or other expert
selected by the Company.

                  (d) The Trustee, in its sole discretion and without the
consent of the Holders, may, and at the request of the Holders of at least 25%
in aggregate principal amount of Notes then Outstanding shall, on behalf of the
Holders, take all actions it deems necessary or appropriate in order to (i)
enforce any of the terms of the Pledge Agreement and (ii) collect and receive
any and all amounts payable in respect of the obligations of the Company
thereunder.

   79
                                                                             73


The Trustee shall have power to institute and to maintain such suits and
proceedings as the Trustee may deem expedient to preserve or protect its
interests and the interests of the Holders in the Pledged Securities (including
power to institute and maintain suits or proceedings to restrain the
enforcement of or compliance with any legislative or other governmental
enactment, rule or order that may be unconstitutional or otherwise invalid if
the enforcement of, or compliance with, such enactment, rule or order would
impair the security interest hereunder or be prejudicial to the interests of
the Holders or of the Trustee).

                                ARTICLE THIRTEEN

                       DEFEASANCE AND COVENANT DEFEASANCE

SECTION 1301.      Company's Option to Effect Defeasance or Covenant Defeasance

                  The Company may, at its option by Board Resolution, at any
time, with respect to the Notes, elect to have either Section 1302 or Section
1303 be applied to all Outstanding Notes upon compliance with the conditions
set forth below in this Article Thirteen.

SECTION 1302.      Defeasance and Discharge

                  Upon the Company"s exercise under Section 1301 of the option
applicable to this Section 1302, the Company shall be deemed to have been
discharged from its obligations with respect to all Outstanding Notes on the
date the conditions set forth in Section 1304 are satisfied (hereinafter,
"defeasance"). For this purpose, such defeasance means that the Company shall
be deemed to have paid and discharged the entire indebtedness represented by
the Outstanding Notes, which shall thereafter be deemed to be "Outstanding"
only for the purposes of Section 1305 and the other Sections of this Indenture
referred to in (A) and (B) below, and to have satisfied all its other
obligations under such Notes and this Indenture insofar as such Notes are
concerned (and the Trustee, at the expense of the Company, shall execute proper
instruments acknowledging the same), except for the following which shall
survive until otherwise terminated or discharged hereunder: (A) the rights of
Holders of Outstanding Notes to receive payments, (solely from monies deposited
in trust) in respect of the principal of, premium, if any, and interest on such
Notes when such payments are due, (B) the Company's obligations with respect to
such Notes under Sections 304, 305, 306, 1002 and 1003, (C) the rights, powers,
trusts, duties and immunities of the Trustee hereunder and (D) this Article
Thirteen. Subject to compliance with this Article Thirteen, the Company may
exercise its option under this Section 1302 notwithstanding the prior exercise
of its option under Section 1303 with respect to the Notes.

SECTION 1303.      Covenant Defeasance

                  Upon the Company's exercise under Section 1301 of the option
applicable to this Section 1303, the Company shall be released from its
obligations under any covenant contained in Section 801(3) and (4) and Section
803 and in Sections 1007 through 1022 with respect to the Outstanding Notes on
and after the date the conditions set forth below are satisfied (hereinafter,
"covenant defeasance"), and the Notes shall thereafter be deemed not to be
"Outstanding" for the purposes of any direction, waiver, consent or declaration
or Act of Holders (and the

   80
                                                                             74


consequences of any thereof) in connection with such covenants, but shall
continue to be deemed "Outstanding" for all other purposes hereunder. For this
purpose, such covenant defeasance means that, with respect to the Outstanding
Notes, 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 covenant,
whether directly or indirectly, by reason of any reference elsewhere herein to
any such covenant or by reason of any reference in any such covenant to any
other provision herein or in any other document and such omission to comply
shall not constitute a Default or an Event of Default under Section 501(6),
but, except as specified above, the remainder of this Indenture and such Notes
shall be unaffected thereby.


SECTION 1304.      Conditions to Defeasance or Covenant Defeasance

                  The following shall be the conditions to application of
either Section 1302 or Section 1303 to the Outstanding Notes:

                  (1) The Company shall irrevocably have deposited or caused to
         be deposited with the Trustee (or another trustee satisfying the
         requirements of Section 607 who shall agree to comply with the
         provisions of this Article Thirteen 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
         benefit of the Holders of such Notes, (A) cash in United States
         dollars, or (B) U.S. Government Obligations or (C) a combination
         thereof, in such amounts as will be 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 other
         qualifying trustee) to pay and discharge, (i) the principal of (and
         premium, if any), and interest on, the Outstanding Notes on the Stated
         Maturity (or Redemption Date, if applicable) of such principal (and
         premium, if any) or installment of interest and (ii) any mandatory
         sinking fund payments or analogous payments applicable to the
         Outstanding Notes on the day on which such payments are due and
         payable in accordance with the terms of this Indenture and of such
         Notes; provided that the Trustee shall have been irrevocably
         instructed to apply such money or the proceeds of such U.S. Government
         Obligations to said payments with respect to the Notes. Before such a
         deposit, the Company may give to the Trustee, in accordance with
         Section 1103 hereof, a notice of its election to redeem all of the
         Outstanding Notes at a future date in accordance with Article Eleven
         hereof, which notice shall be irrevocable. Such irrevocable redemption
         notice, if given, shall be given effect in applying the foregoing. For
         this purpose, "U.S. Government Obligations" means securities that are
         (x) direct obligations of the United States of America for the timely
         payment of which its full faith and credit is pledged or (y)
         obligations of a Person controlled or supervised by and acting as an
         agency or instrumentality of the United States of America the timely
         payment of which is unconditionally guaranteed as a full faith and
         credit obligation by the United States of America, which, in either
         case, are not callable or redeemable at the option of the issuer
         thereof, and shall also include a depository receipt issued by a bank
         (as defined in Section 3(a)(2) of the Securities Act), as custodian
         with respect to any such U.S. Government Obligation or a specific
         payment of principal of or interest on any such U.S. Government
         Obligation held by such custodian for the account of the holder of
         such depository receipt, 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

   81
                                                                             75


         from any amount received by the custodian in respect of the U.S.
         Government Obligation or the specific payment of principal of or
         interest on the U.S. Government Obligation evidenced by such
         depository receipt.

                  (2) No Default or Event of Default with respect to the Notes
         shall have occurred and be continuing on the date of such deposit or,
         insofar as paragraph (9) or (10) of Section 501 hereof is concerned,
         at any time during the period ending on the 123rd day after the date
         of such deposit.

                  (3)  [Reserved]

                  (4) Such defeasance or covenant defeasance shall not result
         in a breach or violation of, or constitute a default under any
         material agreement or instrument (other than this Indenture) to which
         the Company is a party or by which it is bound.

                  (5) In the case of an election under Section 1302, the
         Company shall have delivered to the Trustee an Opinion of Counsel
         stating that (x) the Company has received from, or there has been
         published by, the Internal Revenue Service a ruling, or (y) since
         January 15, 1998, there has been a change in the applicable federal
         income tax law, in either case to the effect, and based thereon such
         opinion shall confirm, that Holders will not recognize income, gain or
         loss for federal income tax purposes as a result of such defeasance
         and will be subject to federal income tax on the same amounts, in the
         same manner and at the same times as would have been the case if such
         defeasance had not occurred.

                  (6) In the case of an election under Section 1303, the
         Company shall have delivered to the Trustee an Opinion of Counsel to
         the effect that the Holders will not recognize income, gain or loss
         for federal income tax purposes as a result of such covenant
         defeasance and will be subject to federal income tax on the same
         amounts, in the same manner and at the same times as would have been
         the case if such covenant defeasance had not occurred.

                  (7) The Company shall have delivered to the Trustee an
         Officer's Certificate and an Opinion of Counsel, each stating that all
         conditions precedent provided for relating to either the defeasance
         under Section 1302 or the covenant defeasance under Section 1303 (as
         the case may be) have been complied with.

SECTION 1305.     Deposited Money and U.S. Government Obligations to Be Held in
                  Trust; Other Miscellaneous Provisions

                  Subject to the provisions of the last paragraph of Section
1003, all money and U.S. Government Obligations (including the proceeds
thereof) deposited with the Trustee (or other qualifying trustee, collectively
for purposes of this Section 1305, the "Trustee") pursuant to Section 1304 in
respect of the Outstanding Notes shall be held in trust and applied by the
Trustee, in accordance with the provisions of such Notes and this Indenture, to
the payment, either directly or through any Paying Agent (including the Company
acting as its own Paying Agent) as the Trustee may determine, to the Holders of
such Notes of all sums due and to become due thereon in respect of principal
(and premium, if any) and interest, but such money


   82
                                                                             76


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. Governmental
Obligations deposited pursuant to Section 1304 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.

                  Anything in this Article Thirteen 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 1304 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 an equivalent defeasance or
covenant defeasance, as applicable, in accordance with this Article.

SECTION 1306.     Reinstatement

                  If the Trustee or any Paying Agent is unable to apply any
money in accordance with Section 1305 by reason of any order or judgment of any
court or governmental authority enjoining, restraining or otherwise prohibiting
such application, then the Company's obligations under this Indenture and the
Notes shall be revived and reinstated as though no deposit had occurred
pursuant to Section 1302 or 1303, as the case may be, until such time as the
Trustee or Paying Agent is permitted to apply all such money in accordance with
Section 1305; provided, however, that if the Company makes any payment of
principal of (or premium, if any) or interest on any Note following the
reinstatement of its obligations, the Company shall be subrogated to the rights
of the Holders of such Notes to receive such payment from the money held by the
Trustee or Paying Agent.

                  This Indenture may be signed in any number of counterparts
each of which so executed shall be deemed to be an original, but all such
counterparts shall together constitute but one and the same Indenture.
