exercise of reasonable care should know, that the opinion, certificate or
representations with respect to the matters upon which his certificate or
opinion is based are erroneous. Any such Opinion of Counsel or certificate or
representations may be based, insofar as it relates to factual matters, upon a
certificate or opinion of, or representations by, an officer or officers of the
Company stating that the information as to such factual matters is in the
possession of the Company, unless such counsel knows that the certificate or
opinion or representations as 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 of the Outstanding Securities of all series or one or more series, as
the case may be, 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. Except as herein otherwise expressly provided, such action
shall become effective when such instrument or instruments or record or both are
delivered to the Trustee and, where it is hereby expressly required, to the
Company. Such instrument or instruments and any such record (and the action
embodied therein and evidenced thereby) are herein sometimes referred to as the
"Act" of the Holders signing such instrument or instruments or so voting at any
such meeting. Proof of execution of any such instrument or of a writing
appointing any such agent, or of the holding by any Person of a Security, shall
be sufficient for

                                      -11-

<PAGE>

any purpose of this Indenture and (subject to Section 612) conclusive in favor
of the Trustee and the Company and any agent of the Trustee or the Company, if
made in the manner provided in this Section. The record of any meeting of
Holders of Securities shall be proved in the manner provided in Section 1506.

         (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 his 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 reasonable manner which the Trustee deems sufficient.

         (c)      The ownership of Registered Securities shall be proved by the
Security Register or by a certificate of the Security Registrar.

         (d)      If the Company shall solicit from the Holders of Registered
Securities any request, demand, authorization, direction, notice, consent,
waiver or other Act, the Company may, at its option, in 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
Securities have authorized or agreed or consented to such request, demand,
authorization, direction, notice, consent, waiver or other Act, and for that
purpose the Outstanding Securities 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 Security shall bind every
future Holder of the same Security and the Holder of every Security issued upon
the registration of transfer thereof or in exchange therefor or in lieu thereof
in respect of anything done, omitted or suffered to be done by the Trustee, any
Security Registrar, any Paying Agent, any Authenticating Agent or the Company in
reliance thereon, whether or not notation of such action is made upon such
Security.

         SECTION 105.      NOTICES, ETC., TO THE TRUSTEE AND COMPANY.

                                      -12-

<PAGE>

         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, Attention:
Corporate Trust Department and referencing this Indenture, 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 of
Registered Securities 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 such Holder affected by such
event, at his address as it appears in the Security 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 of Registered Securities 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 of Registered Securities. 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.

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

         Any request, demand, authorization, direction, notice, consent or
waiver required or permitted under this Indenture shall be in the English
language, except that any published notice may be in an official language of the
country of publication.

         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.

         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 and the
Security Guarantors shall bind each of their respective successors and assigns,
whether so expressed or not.

         SECTION 109.      SEPARABILITY CLAUSE.

         In case any provision in this Indenture or in any Security or any
Security Guarantee 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 any Security Guarantee or in the
Securities, express or implied, shall give to any Person, other than the parties
hereto, any Security Registrar, any Paying Agent, any Authenticating Agent and
their successors hereunder and the Holders any benefit or any legal or equitable
right, remedy or claim under this Indenture.

         SECTION 111.      NO PERSONAL LIABILITY.

         No recourse under or upon any obligation, covenant or agreement
contained in this Indenture, in any Security Guarantee, in any Security, or
because of any indebtedness evidenced thereby, shall be had against any
promoter, as such, or against any past, present or future shareholder, officer
or director, as such, of the Company or any Security Guarantor, or of any
successor of the Company or any Security Guarantor, either directly or through
the Company or such Security Guarantor or any successor, under any rule of law,
statute or constitutional provision or by the enforcement of any assessment or
by any legal or equitable proceeding or otherwise, all such liability being
expressly waived and released by the acceptance of the Securities by the Holders
thereof and as part of the consideration for the issue of the Securities.

         SECTION 112.      GOVERNING LAW.

         This Indenture, the Security Guarantees and the Securities 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 TIA that are required to be
part of this Indenture and shall, to the extent applicable, be governed by such
provisions.

         SECTION 113.      LEGAL HOLIDAYS.

         In any case where any Interest Payment Date, Redemption Date, Repayment
Date, sinking fund payment date, Stated Maturity or Maturity of any Security or
the last date on which a Holder has the right to convert or exchange a Security
at a particular conversion or exchange price shall not be a Business Day at any
Place of Payment, then (notwithstanding any other provision of this Indenture or
any Security other than a provision in the Securities of any series

Make-Whole Amount, if any) need not be made at such Place of Payment on such

date, but may be made on the next succeeding Business Day at such Place of
Payment with the same force and effect as if made on the Interest Payment Date,
Redemption Date, Repayment Date or sinking fund payment date, or at the Stated
Maturity or Maturity or on such last day for conversion or exchange, provided
that no interest shall accrue on the amount so payable for the period from and
after such Interest Payment Date, Redemption Date, Repayment Date, sinking fund
payment date, Stated Maturity or Maturity or on such last day for conversion or
exchange, as the case may be.

         The Securities and the Trustee's certificate of authentication with
respect thereto and the Security Guarantees shall be in substantially the forms
set forth, or referenced, in Exhibit A and Exhibit B, respectively, annexed
hereto, or in such other form or forms as shall be established by or pursuant to

letters, numbers or other marks of identification and such legends or
endorsements placed thereon as may be required to comply with applicable tax
laws or the rules of any securities exchange or as may, consistently herewith,
be determined by the officers executing such Securities and Security Guarantees,
as evidenced by their execution of such Securities and Security Guarantees.

         The definitive Securities and the Security Guarantees shall be printed,
lithographed or engraved or produced by any combination of these methods on a
steel engraved border or steel engraved borders or may be produced in any other
manner, all as determined by the officers of the Company executing such

                                    [_______________], as Trustee

         SECTION 203.      SECURITIES ISSUABLE IN GLOBAL FORM.

         If Securities of or within a series are issuable in global form, as
specified as contemplated by Section 301, then, notwithstanding clause (8) of
Section 301 and the provisions of Section 302, any such Security shall represent
such of the Outstanding Securities of such series as shall be specified therein
and may provide that it shall represent the aggregate amount of Outstanding
Securities of such series from time to time endorsed thereon and that the
aggregate amount of Outstanding Securities of such series represented thereby
may from time to time be increased or decreased to reflect exchanges. Any
endorsement of a Security in global form to reflect the amount, or any increase
or decrease in the amount, of Outstanding Securities represented thereby shall
be made by the Trustee in such manner and upon written instruction given by such
Person or Persons as shall be specified therein or in the Company Order to be
delivered to the Trustee pursuant to Section 303 or 304. Subject to the
provisions of Section 303 and, if applicable, Section 304, the Trustee shall
deliver and redeliver any Security in permanent global form in the manner and
upon written instructions given by the Person or Persons specified therein or in
the applicable Company Order. If a Company Order pursuant to Section 303 or 304
has been, or simultaneously is, delivered, any instructions by the Company with
respect to endorsement or delivery or redelivery of a Security in global form
shall be in writing but need not comply with Section 102 and need not be
accompanied by an Opinion of Counsel.

         The provisions of the last sentence of Section 303 shall apply to any
Security represented by a Security in global form if such Security was never
issued and sold by the Company and the Company delivers to the Trustee the
Security in global form together with written instructions (which need not
comply with Section 102 and need not be accompanied by an Opinion of Counsel)
with regard to the reduction in the principal amount of Securities represented
thereby, together with the written statement contemplated by the last sentence
of Section 303.

         Notwithstanding the provisions of Section 307, unless otherwise
specified as contemplated by Section 301, payment of principal of and any
premium or Make-Whole Amount and interest on any Security in permanent global
form shall be made to the Person or Persons specified therein.

         Notwithstanding the provisions of Section 308 and except as provided in
the preceding paragraph, the Company, the Trustee and any agent of the Company
and the Trustee shall treat as the Holder of such principal amount of
Outstanding Securities represented by a permanent global Security the Holder of
such permanent global Security in registered form.

the form of Exhibit B hereto.

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

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

         If all of the Securities of any series are not to be issued at one time
and if the Board Resolution or supplemental indenture establishing such series
shall so permit, such Company Order may set forth procedures acceptable to the
Trustee for the issuance of such Securities and determining the terms of
particular Securities of such series, such as interest rate or formula, maturity
date, date of issuance and date from which interest shall accrue. In
authenticating such Securities, and accepting the additional responsibilities
under this Indenture in relation to such Securities, the Trustee shall be
entitled to receive, and (subject to Section 612 and TIA Section 315(a) through
315(d)) shall be fully protected in conclusively relying upon:

                  (i)      an Opinion of Counsel complying with Section 102 and
         stating that:

                           (a)      the form or forms of such Securities have
                   been, or will have been upon compliance with such procedures
                   as may be specified therein, established in conformity with
                   the provisions of this Indenture;

                           (b)      the terms of such Securities have been, or
                   will have been upon compliance with such procedures as may be
                   specified therein, established in conformity with the
                   provisions of this Indenture; and

                           (c)      such Securities, when completed pursuant to
                   such procedures as may be specified therein, and executed and
                   delivered by the Company to the Trustee for authentication in
                   accordance with this Indenture, authenticated and delivered
                   by the Trustee in accordance with this Indenture and issued
                   by the

                                      -21-

<PAGE>

                   Company in the manner and subject to any conditions specified
                   in such Opinion of Counsel, will constitute legal, valid and
                   binding obligations of the Company, enforceable in accordance
                   with their terms, subject to applicable bankruptcy,
                   insolvency, reorganization and other similar laws of general
                   applicability relating to or affecting the enforcement of
                   creditors' rights generally and to general equitable
                   principles and to such other matters as may be specified
                   therein; and

                   (ii)    an Officers' Certificate complying with Section 102
         and stating that all conditions precedent provided for in this
         Indenture relating to the issuance of such Securities have been, or
         will have been upon compliance with such procedures as may be specified
         therein, complied with and that, to the best of the knowledge of the
         signers of such certificate, no Event of Default with respect to such
         Securities shall have occurred and be continuing upon such issuance.

         Notwithstanding the provisions of Section 301 and of the preceding
paragraph, if all the Securities of any series are not to be issued at one time,
it shall not be necessary to deliver a Company Order, an Opinion of Counsel or
an Officers' Certificate otherwise required pursuant to the preceding paragraph
at the time of issuance of each Security of such series, but such order, opinion
and certificate, with appropriate modifications to cover such future issuances,
shall be delivered at or before the time of issuance of the first Security of
such series.

         The Trustee shall not be required to authenticate such Securities if
the issue of such Securities pursuant to this Indenture will affect the
Trustee's own rights, duties, obligations or immunities under the Securities and
this Indenture or otherwise in a manner which is not reasonably acceptable to
the Trustee.

         Each Registered Security shall be dated the date of its authentication.

         No Security shall be entitled to any benefit under this Indenture or be
valid or obligatory for any purpose unless there appears on such Security a
certificate of authentication substantially in the form provided for herein duly
executed by the Trustee by manual signature of an authorized officer, and such
certificate upon any Security shall be conclusive evidence, and the only
evidence, that such Security has been duly authenticated and delivered hereunder
and is entitled to the benefits of this Indenture. Notwithstanding the
foregoing, if any Security shall have been authenticated and delivered hereunder
but never issued and sold by the Company, and the Company shall deliver such
Security to the Trustee for cancellation as provided in Section 309 together
with a written statement (which need not comply with Section 102 and need not be
accompanied by an Opinion of Counsel) stating that such Security has never been
issued or sold by the Company, for all purposes of this Indenture such Security
shall be deemed never to have been authenticated and delivered hereunder and
shall never be entitled to the benefits of this Indenture.

         SECTION 304.      TEMPORARY SECURITIES.

         (a)      Pending the preparation of definitive Securities of any
series, the Company may execute, and upon Company Order the Trustee shall
authenticate and deliver, temporary

                                      -22-

<PAGE>

Securities which are printed, lithographed, typewritten, mimeographed or
otherwise produced, in any authorized denomination, substantially of the tenor
of the definitive Securities in lieu of which they are issued, in registered
form, and with such appropriate insertions, omissions, substitutions and other
variations as the officers of the Company executing such Securities may
determine, as conclusively evidenced by their execution of such Securities. In
the case of Securities of any series, such temporary Securities may be in global
form.

         Except in the case of temporary Securities in global form (which shall
be exchanged in accordance with Section 304(b) or as otherwise provided in or
pursuant to a Board Resolution), if temporary Securities of any series are
issued, the Company will cause definitive Securities of that series to be
prepared without unreasonable delay. After the preparation of definitive
Securities of such series, the temporary Securities of such series shall be
exchangeable for definitive Securities of such series upon surrender of the
temporary Securities of such series at the office or agency of the Company in a
Place of Payment for that series, without charge to the Holder. Upon surrender
for cancellation of any one or more temporary Securities of any series, the
Company shall execute and the Trustee shall authenticate and deliver in exchange
therefor a like principal amount of definitive Securities of the same series of
authorized denominations. Until so exchanged, the temporary Securities of any
series shall in all respects be entitled to the same benefits under this
Indenture as definitive Securities of such series.

         (b)      Unless otherwise provided as contemplated in Section 301, this
Section 304(b) shall govern the exchange of temporary Securities issued in
global form other than through the facilities of DTC. If any such temporary
Security is issued in global form, then such temporary global Security shall,
unless otherwise provided therein, be delivered to the London office of a
depository or common depository (the "Common Depository"), for the benefit of
Euroclear and/or Clearstream.

         Without unnecessary delay but in any event not later than the date
specified in, or determined pursuant to the terms of, any such temporary global
Security (the "Exchange Date"), the Company shall deliver to the Trustee
definitive Securities, in an aggregate principal amount equal to the principal
amount of such temporary global Security, executed by the Company. On or after
the Exchange Date, such temporary global Security shall be surrendered by the
Common Depository to the Trustee, as the Company's agent for such purpose, to be
exchanged, in whole or from time to time in part, for definitive Securities
without charge, and the Trustee shall authenticate and deliver, in exchange for
each portion of such temporary global Security, an equal aggregate principal
amount of definitive Securities of or within the same series of authorized
denominations and of like tenor as the portion of such temporary global Security
to be exchanged. The definitive Securities to be delivered in exchange for any
such temporary global Security shall be in registered form or permanent global
registered form, as specified as contemplated by Section 301, and, if any
combination thereof is so specified, as requested by the beneficial owner
thereof; provided, however, that, unless otherwise specified in such temporary
global Security, upon such presentation by the Common Depository, such temporary
global Security is accompanied by a certificate dated the Exchange Date or a
subsequent date and signed by Euroclear as to the portion of such temporary
global Security, if any, held for its account then to be exchanged and a
certificate dated the Exchange Date or a subsequent date and signed by
Clearstream as to the portion of such temporary global Security, if any, held
for its

                                      -23-

<PAGE>

account then to be exchanged, each in the form set forth in Exhibit C-2 to this
Indenture or in such other form as may be established pursuant to Section 301.

         Unless otherwise specified in such temporary global Security, the
interest of a beneficial owner of Securities of a series in a temporary global
Security shall be exchanged for definitive Securities of the same series and of
like tenor following the Exchange Date when the account holder instructs
Euroclear or Clearstream, as the case may be, to request such exchange on his
behalf and delivers to Euroclear or Clearstream, as the case may be, a
certificate in the form set forth in Exhibit C-1 to this Indenture (or in such
other form as may be established pursuant to Section 301), dated no earlier than
15 days prior to the Exchange Date, copies of which certificate shall be
available from the offices of Euroclear or Clearstream, the Trustee, any
Authenticating Agent appointed for such series of Securities and each Paying
Agent. Unless otherwise specified in such temporary global Security, any such
exchange shall be made free of charge to the beneficial owners of such temporary
global Security, except that a Person receiving definitive Securities must bear
the cost of insurance, postage, transportation and the like unless such Person
takes delivery of such definitive Securities in person at the offices of
Euroclear or Clearstream.

         Until exchanged in full as hereinabove provided, the temporary
Securities of any series shall in all respects be entitled to the same benefits
under this Indenture as definitive Securities of the same series and of like
tenor authenticated and delivered hereunder, except that, unless otherwise
specified as contemplated by Section 301, interest payable on a temporary global
Security on an Interest Payment Date for Securities of such series occurring
prior to the applicable Exchange Date shall be payable to Euroclear or
Clearstream on such Interest Payment Date upon delivery by Euroclear or
Clearstream to the Trustee of a certificate or certificates in the form set
forth in Exhibit C-2 to this Indenture (or in such other forms as may be
established pursuant to Section 301), for credit without further interest on or
after such Interest Payment Date to the respective accounts of Persons who are
the beneficial owners of such temporary global Security on such Interest Payment
Date and who have each delivered to Euroclear or Clearstream, as the case may
be, a certificate dated no earlier than 15 days prior to the Interest Payment
Date occurring prior to such Exchange Date in the form set forth as Exhibit C-1
to this Indenture (or in such other forms as may be established pursuant to
Section 301). Notwithstanding anything to the contrary herein contained, the
certifications made pursuant to this paragraph shall satisfy the certification
requirements of the preceding two paragraphs of this Section 304(b) and of the
third paragraph of Section 303 of this Indenture and the interests of the
Persons who are the beneficial owners of the temporary global Security with
respect to which such certification was made will be exchanged for definitive
Securities of the same series and of like tenor on the Exchange Date or the date
of certification if such date occurs after the Exchange Date, without further
act or deed by such beneficial owners. Except as otherwise provided in this
paragraph, no payments of principal or interest owing with respect to a
beneficial interest in a temporary global Security will be made unless and until
such interest in such temporary global Security shall have been exchanged for an
interest in a definitive Security. Any interest so received by Euroclear or
Clearstream and not paid as herein provided shall be returned to the Trustee
prior to the expiration of two years after such Interest Payment Date in order
to be repaid to the Company.

         SECTION 305.      REGISTRATION, REGISTRATION OF TRANSFER AND EXCHANGE.

         The Company shall cause to be kept at the Corporate Trust Office of the
Trustee or in any office or agency of the Company in a Place of Payment a
register for each series of Securities (the registers maintained in such office
or in any such office or agency of the Company in a Place of Payment being
herein sometimes referred to collectively as the "Security Register") in which,
subject to such reasonable regulations as it or the Security Registrar may
prescribe, the Company shall provide for the registration of Registered
Securities and of transfers of Registered Securities. The Security Register
shall be in written form or any other form capable of being converted into
written form within a reasonable time. The Trustee, at its Corporate Trust
Office, is hereby initially appointed "Security Registrar" for the purpose of
registering Registered Securities and transfers of Registered Securities on such
Security Register as herein provided. In the event that the Trustee shall cease
to be Security Registrar, it shall have the right to examine the Security
Register at all reasonable times and to require that a copy of the Security
Register in written form be delivered to it from time to time as reasonably
requested.

         Subject to the provisions of this Section 305, upon surrender for
registration of transfer of any Registered Security of any series at any office
or agency of the Company in a Place of Payment for that series, the Company
shall execute, and the Trustee shall authenticate and deliver, in the name of
the designated transferee or transferees, one or more new Registered Securities
of the same series, of any authorized denominations and of a like aggregate
principal amount, bearing a number not contemporaneously outstanding, and
containing identical terms and provisions.

         Subject to the provisions of this Section 305, at the option of the
Holder, Registered Securities of any series may be exchanged for other
Registered Securities of the same series, of any authorized denomination or
denominations and of a like aggregate principal amount, containing identical
terms and provisions, upon surrender of the Registered Securities to be
exchanged at any such office or agency. Whenever any such Registered Securities
are so surrendered for exchange, the Company shall execute, and the Trustee
shall authenticate and deliver, the Registered Securities which the Holder
making the exchange is entitled to receive.

         Notwithstanding the foregoing, except as otherwise specified as
contemplated by Section 301, any permanent global Security shall be exchangeable
only as provided in this paragraph. If the depository for any permanent global
Security is DTC, then, unless the terms of such global Security expressly permit
such global Security to be exchanged in whole or in part for definitive
Securities, a global Security may be transferred, in whole but not in part, only
to a nominee of DTC, or by a nominee of DTC to DTC, or to a successor to DTC for
such global Security selected or approved by the Company or to a nominee of such
successor to DTC. If at any time DTC notifies the Company that it is unwilling
or unable to continue as depository for the applicable global Security or
Securities or if at any time DTC ceases to be a clearing agency registered under
the Exchange Act if so required by applicable law or regulation, the Company
shall appoint a successor depository with respect to such global Security or
Securities. If (x) a successor depository for such global Security or Securities
is not appointed by the Company within 90 days after the Company receives such
notice or becomes aware of such unwillingness, inability or ineligibility, (y)
an Event of Default has occurred and is continuing and the beneficial

                                      -25-

<PAGE>

owners representing a majority in principal amount of the applicable series of
Securities represented by such global Security or Securities advise DTC to cease
acting as depository for such global Security or Securities or (z) the Company,
in its sole discretion, determines at any time that all Outstanding Securities
(but not less than all) of any series issued or issuable in the form of one or
more global Securities shall no longer be represented by such global Security or
Securities (provided, however, the Company may not make such determination
during the 40-day restricted period provided by Regulation S under the
Securities Act or during any other similar period during which the Securities
must be held in global form as may be required by the Securities Act), then the
Company (i) shall notify the Trustee of the occurrence of any of the events
specified in (x), (y) or (z) and (ii) shall execute, and, upon receipt of a
Company Order, the Trustee shall authenticate and deliver definitive Securities
of like series, rank, tenor and terms in definitive form in an aggregate
principal amount equal to the principal amount of such global Security or
Securities and registered to such holder or holders as specified by DTC. If any
beneficial owner of an interest in a permanent global Security is otherwise
entitled to exchange such an interest for Securities of such series and of like
tenor and principal amount of another authorized form and denomination, as
specified as contemplated by Section 301 and provided that any applicable notice
provided in the permanent global Security shall have been given, then without
unnecessary delay but in any event not later than the earliest date on which
such interest may be so exchanged, the Company shall execute, and the Trustee
shall authenticate and deliver definitive Securities in aggregate principal
amount equal to the principal amount of such beneficial owner's interest in such
permanent global Security. On or after the earliest date on which such interests
may be so exchanged, such permanent global Security shall be surrendered for
exchange by DTC or such other depository as shall be specified in the Company
Order with respect thereto to the Trustee, as the Company's agent for such
purpose; provided, however, that no such exchanges may occur during a period
beginning at the opening of business 15 days before any selection of Securities
to be redeemed and ending on the relevant Redemption Date if the Security for
which exchange is requested may be among those selected for redemption. If a
Registered Security is issued in exchange for any portion of a permanent global
Security after the close of business at the office or agency where such exchange
occurs on (i) any Regular Record Date and before the opening of business at such
office or agency on the relevant Interest Payment Date, or (ii) any Special
Record Date and before the opening of business at such office or agency on the
related proposed date for payment of Defaulted Interest, interest or Defaulted
Interest, as the case may be, will not be payable on such Interest Payment Date
or proposed date for payment, as the case may be, in respect of such Registered
Security, but will be payable on such Interest Payment Date or proposed date for
payment, as the case may be, only to the Person to whom interest in respect of
such portion of such permanent global Security is payable in accordance with the
provisions of this Indenture.

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

         Every Registered Security presented or surrendered for registration of
transfer or for exchange or redemption shall (if so required by the Company or
the Security Registrar) be duly endorsed, or be accompanied by a written
instrument of transfer in form satisfactory to the

                                      -26-

<PAGE>

Security Registrar, duly executed by the Holder thereof or his attorney duly
authorized in writing.

         No service charge shall be made for any registration of transfer or
exchange of Securities, but the Company may require payment of a sum sufficient
to cover any tax or other governmental charge that may be imposed in connection
with any registration of transfer or exchange of Securities, other than
exchanges pursuant to Section 304, 906, 1107 or 1305 not involving any transfer.

         The Company or the Trustee, as applicable, shall not be required (i) to
issue, register the transfer of or exchange any Security if such Security may be
among those selected for redemption during a period beginning at the opening of
business 15 days before selection of the Securities to be redeemed under Section
1103 and ending at the close of business on the day of the mailing of the
relevant notice of redemption, or (ii) to register the transfer of or exchange
any Registered Security so selected for redemption in whole or in part, except,
in the case of any Registered Security to be redeemed in part, the portion
thereof not to be redeemed, or (iii) to issue or to register the transfer or
exchange of any Security which has been surrendered for repayment at the option
of the Holder, except the portion, if any, of such Security not to be so repaid.

         SECTION 306.      MUTILATED, DESTROYED, LOST AND STOLEN SECURITIES.

         If any mutilated Security is surrendered to the Trustee or the Company,
together with such security or indemnity as may be required by the Company or
the Trustee to save each of them or any agent of either of them harmless, the
Company shall execute and the Trustee shall authenticate and deliver in exchange
therefor a new Security of the same series and principal amount, and the
Security Guarantors shall execute a replacement Security Guarantee, containing
identical terms and provisions and bearing a number not contemporaneously
outstanding.

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

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

         Upon the issuance of any new Security under this Section, the Company
may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed

                                      -27-

<PAGE>

in relation thereto and any other expenses (including the fees and expenses of
the Trustee) connected therewith.

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

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

         SECTION 307.      PAYMENT OF INTEREST; INTEREST RIGHTS PRESERVED.

         Except as otherwise specified with respect to a series of Securities in
accordance with the provisions of Section 301, interest on any Registered
Security that is payable, and is punctually paid or duly provided for, on any
Interest Payment Date shall be paid to the Person in whose name that Security
(or one or more Predecessor Securities) is registered at the close of business
on the Regular Record Date for such interest at the office or agency of the
Company maintained for such purpose pursuant to Section 1002; provided, however,
that each installment of interest on any Registered Security may at the
Company's option be paid by (i) mailing a check for such interest, payable to or
upon the written order of the Person entitled thereto pursuant to Section 308,
to the address of such Person as it appears on the Security Register or (ii)
transfer to an account maintained by the payee located inside the United States.

         Unless otherwise provided as contemplated by Section 301, every
permanent global Security will provide that interest, if any, payable on any
Interest Payment Date will be paid to DTC, Euroclear and/or Clearstream, as the
case may be, with respect to that portion of such permanent global Security held
for its account by DTC, Euroclear or Clearstream, as the case may be, for the
purpose of permitting such party to credit the interest received by it in
respect of such permanent global Security to the accounts of the beneficial
owners thereof.

         Except as otherwise specified with respect to a series of Securities in
accordance with the provisions of Section 301, any interest on any Registered
Security of any series that is payable, but is not punctually paid or duly
provided for, on any Interest Payment Date (herein called "Defaulted Interest")
shall forthwith cease to be payable to the registered Holder thereof on the
relevant Regular Record Date by virtue of having been such Holder, and such
Defaulted Interest may be paid by the Company, at its election in each case, as
provided in clause (1) or (2) below:

         (1)      The Company may elect to make payment of any Defaulted
Interest to the Persons in whose names the Registered Securities of such series
(or their respective Predecessor Securities) are registered at the close of
business on a Special Record Date for the payment of such Defaulted Interest,
which shall be fixed in the following manner. The Company shall notify the
Trustee in writing of the amount of Defaulted Interest proposed to be paid on
each Registered

                                      -28-

<PAGE>

Security of such series and the date of the proposed payment (which shall not be
less than 20 days after such notice is received by the Trustee), and at the same
time the Company shall deposit with the Trustee an amount of money in the
currency or currencies, currency unit or units or composite currency or
currencies in which the Securities of such series are payable (except as
otherwise specified pursuant to Section 301 for the Securities of such series)
equal to the aggregate amount proposed to be paid in respect of such Defaulted
Interest or shall make arrangements satisfactory to the Trustee for such deposit
on or prior to the date of the proposed payment, such money when deposited to be
held in trust for the benefit of the Persons entitled to such Defaulted Interest
as in this clause provided. Thereupon the Trustee shall fix a Special Record
Date for the payment of such Defaulted Interest which shall be 10 days after the
receipt by the Trustee of the notice of the proposed payment. The Trustee shall
promptly notify the Company of such Special Record Date and, in the name and at
the expense of the Company, shall cause notice of the proposed payment of such
Defaulted Interest and the Special Record Date therefor to be mailed,
first-class postage prepaid, to each Holder of Registered Securities of such
series at his address as it appears in the Security Register not less than 10
days prior to such Special Record Date. Notice of the proposed payment of such
Defaulted Interest and the Special Record Date therefor having been mailed as
aforesaid, such Defaulted Interest shall be paid to the Persons in whose names
the Registered Securities of such series (or their respective Predecessor
Securities) are registered at the close of business on such Special Record Date
and shall no longer be payable pursuant to the following clause (2).

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

         Subject to the foregoing provisions of this Section and Section 305,
each Security delivered under this Indenture upon registration of transfer of or
in exchange for or in lieu of any other Security shall carry the rights to
interest accrued and unpaid, and to accrue, which were carried by such other
Security.

         Subject to the provisions of Section 1402 and except as otherwise
specified with respect to a series of Securities in accordance with the
provisions of Section 301, in the case of any Security which is converted or
exchanged after any Regular Record Date and on or prior to the next succeeding
Interest Payment Date (other than any Security, the principal of (or premium, if
any, on) which shall become due and payable, whether at a Stated Maturity or by
declaration of acceleration, call for redemption, or otherwise, prior to such
Interest Payment Date), interest whose Stated Maturity is on such Interest
Payment Date shall be payable on such Interest Payment Date notwithstanding such
conversion or exchange, and such interest (whether or not punctually paid or
duly provided for) shall be paid to the Person in whose name that Security (or
one or more Predecessor Securities) is registered at the close of business on
such Regular Record Date. Except as otherwise expressly provided in the
immediately preceding sentence, in the case of any Security which is converted
or exchanged, interest whose Stated Maturity is after the date of conversion or
exchange of such Security shall not be payable.

         Prior to due presentment of a Registered Security for registration of
transfer, the Company, the Trustee and any agent of the Company or the Trustee
may treat the Person in whose name such Registered Security is registered as the
owner of such Security for the purpose of receiving payment of principal of (and
premium or Make-Whole Amount, if any), and (subject to Sections 305 and 307)
interest on, such Registered Security and for all other purposes whatsoever,
whether or not such Registered Security be overdue, and neither the Company, the
Trustee nor any agent of the Company or the Trustee shall be affected by notice
to the contrary.

         None of the Company, the Trustee, any Paying Agent or the Security
Registrar will have any responsibility or liability for any aspect of the
records relating to or payments made on account of beneficial ownership
interests of a Security in global form or for maintaining, supervising or
reviewing any records relating to such beneficial ownership interests.

         Notwithstanding the foregoing, with respect to any global Security,
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 any depository, as a Holder, with respect to
such global Security or impair, as between such depository and owners of
beneficial interests in such global Security, the operation of customary
practices governing the exercise of the rights of such depository (or its
nominee) as Holder of such global Security.

         SECTION 309.      CANCELLATION.

         All Securities surrendered for payment, redemption, repayment at the
option of the Holder, registration of transfer or exchange or for credit against
any sinking fund payment shall, if surrendered to any Person other than the
Trustee, be delivered to the Trustee, and any such Securities surrendered
directly to the Trustee for any such purpose shall be promptly canceled by it.
The Company may at any time deliver to the Trustee for cancellation any
Securities previously authenticated and delivered hereunder which the Company
may have acquired in any manner whatsoever, and may deliver to the Trustee (or
to any other Person for delivery to the Trustee) for cancellation any Securities
previously authenticated hereunder which the Company has not issued and sold,
and all Securities so delivered shall be promptly cancelled by the Trustee. If
the Company shall so acquire any of the Securities, however, such acquisition
shall not operate as a redemption or satisfaction of the indebtedness
represented by such Securities unless and until the same are surrendered to the
Trustee for cancellation. No Securities shall be authenticated in lieu of or in
exchange for any Securities canceled as provided in this Section, except as
expressly permitted by this Indenture. Cancelled Securities held by the Trustee
shall be destroyed by the Trustee, subject to applicable records retention
requirements, and, if required in writing by the Company, the Trustee shall
deliver a certificate of such destruction to the Company, unless by a Company
Order the Company directs their return to it.

Additional Amounts, as provided in Section 1010), and the Trustee, upon receipt
of a Company Order, and at the expense of the Company, shall execute proper

                  series which have been destroyed, lost or stolen and which
                  have been replaced or paid as provided in Section 306, and
                  (ii) Securities of such series for whose payment money has

                                    (i)     have become due and payable, or

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

                                    (iii)   if redeemable at the option of the

                           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

                  entire indebtedness on such Securities, for principal (and

                                      -31-

<PAGE>

                  premium or Make-Whole Amount, if any) and interest, and any
                  Additional Amounts with respect thereto, to the date of such
                  deposit (in the case of Securities which have become due and
                  payable) or the Stated Maturity or Redemption Date, as the
                  case may be;

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

         (3)      The Company has delivered to the Trustee an Officers'
Certificate and an Opinion of Counsel, each stating that all conditions
precedent herein provided for relating to the satisfaction and discharge of this
Indenture as to such series have been complied with.

         Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Trustee and any predecessor Trustee under
Section 606, the obligations of the Company to any Authenticating Agent under
Section 611 and, if money shall have been deposited with and held by the Trustee

outstanding hereunder, the Trustee shall be required to execute an instrument
acknowledging satisfaction and discharge of this Indenture only if requested to
do so with respect to Securities of a particular series as to which it is
Trustee and if the other conditions thereto are met.

money deposited with the Trustee pursuant to Section 401 shall be held in trust
and applied by it, in accordance with the provisions of the Securities 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 Persons entitled thereto, of the principal (and premium or
Make-Whole Amount, if any), and any interest and Additional Amounts for whose
payment such money has been deposited with or received by the Trustee, but such
money need not be segregated from other funds except to the extent required by
law.

Company is directly responsible or liable as obligor or guarantor), having a
principal amount outstanding in excess of $10,000,000 (other than indebtedness
which is non-recourse to the Company or the Subsidiaries), whether such
indebtedness now exists or shall hereafter be created, which default shall have
resulted in such indebtedness being declared due and payable prior to the date
on which it would otherwise have become due and payable, without such

such Security Guarantee in accordance with Section 1707 hereof) and such
condition shall have continued for a period of 30 days after written notice of
such condition requiring the same to be remedied and stating that such notice is

                  (D)      makes a general assignment for the benefit of its
         creditors; or

         (8)      a court of competent jurisdiction enters an order or decree

time Outstanding 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
Outstanding Securities of each such affected series (voting as a single class)
by written notice to the Company and the Trustee may declare the principal (or,
if any Securities are Original Issue Discount Securities or Indexed Securities,
such portion of the principal as may be specified in the terms thereof) of, and
the Make-Whole Amount, if any, on, all the Securities of that series to be due
and payable immediately, by a notice in writing to the Company (and to the
Trustee if given by the Holders), and upon any such declaration such principal
or specified portion thereof shall become immediately due and payable.

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

         (1)      the Company has paid or deposited with the Trustee a sum
sufficient to pay in the currency, currency unit or composite currency in which
the Securities of such series is payable (except as otherwise specified pursuant
to Section 301 for the Securities of such series):

                  (A)      all overdue installments of interest on and any
         Additional Amounts payable in respect of all Outstanding Securities of
         that series;

                  (B)      the principal of (and premium or Make-Whole Amount,
         if any, on) any Outstanding Securities of that series which have become
         due otherwise than by such declaration of acceleration and interest
         thereon at the rate or rates borne by or provided for in such
         Securities;

                  (C)      to the extent that payment of such interest is
         lawful, interest upon overdue installments of interest and any
         Additional Amounts at the rate or rates borne by or provided for in
         such Securities; and

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

         (2)      all Events of Default with respect to Securities of that
series, other than the nonpayment of the principal of (or premium or Make-Whole
Amount, if any) or interest on Securities of that series which have become due
solely by such declaration of acceleration, have been cured or waived as
provided in Section 513.

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

         SECTION 503.      COLLECTION OF INDEBTEDNESS AND SUITS FOR ENFORCEMENT
BY TRUSTEE.

         The Company covenants that if:

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

         (2)      default is made in the payment of the principal of (or premium
or Make-Whole Amount, if any, on) any Security of any series at its Maturity,
then the Company will, upon demand of the Trustee, pay to the Trustee, for the
benefit of the Holders of such Securities of

                                      -35-

<PAGE>

such series, the whole amount then due and payable on such Securities for
principal (and premium or Make-Whole Amount, if any) and interest and Additional
Amounts, with interest upon any overdue principal (and premium or Make-Whole
Amount, if any) and, to the extent that payment of such interest shall be
legally enforceable, upon any overdue installments of interest or Additional
Amounts, if any, at the rate or rates borne by or provided for in such
Securities, and, in addition thereto, such further amount as shall be sufficient
to cover the costs and expenses of collection, including the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel.

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

         If an Event of Default with respect to Securities of any series occurs
and is continuing, the Trustee may in its discretion proceed to protect and
enforce its rights and the rights of the Holders of Securities of such series 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 any Security Guarantee 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, any Security Guarantor or any other
obligor upon the Securities or the property of the Company, any Security
Guarantor or of such other obligor or their creditors, the Trustee (irrespective
of whether the principal of the Securities of any series 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 or any Security
Guarantor for the payment of overdue principal, premium or Make-Whole Amount, 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, or such lesser
amount as may be provided for in the Securities of such series, of principal
(and premium or Make-Whole Amount, if any) and interest and Additional Amounts,
if any, owing and unpaid in respect of the Securities and to file such other
papers or documents and take such other actions (such as sitting on a committee
of creditors) as may be 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

                                      -36-

<PAGE>

         (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
other similar official) in any such judicial proceeding is hereby authorized by
each Holder of Securities of such series to make such payments to the Trustee,
and in the event that the Trustee shall consent to the making of such payments
directly to the Holders, to pay to the Trustee any amount due to it for the
reasonable compensation, expenses, disbursements and advances of the Trustee and
any predecessor Trustee, their agents and counsel, and any other amounts due the
Trustee or any predecessor 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 of a Security
any plan of reorganization, arrangement, adjustment or composition affecting the
Securities or the rights of any Holder thereof, or to authorize the Trustee to
vote in respect of the claim of any Holder of a Security in any such proceeding.

         SECTION 505.      TRUSTEE MAY ENFORCE CLAIMS WITHOUT POSSESSION OF
SECURITIES.

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

         SECTION 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 or
Make-Whole Amount, if any) or interest and any Additional Amounts, upon
presentation of the Securities, and the notation thereon of the payment if only
partially paid and upon surrender thereof if fully paid:

                  FIRST:   To the payment of all amounts due the Trustee and any

                           upon the Securities for principal (and premium or
                           Make-Whole Amount, if any) and interest and any
                           Additional Amounts payable, 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 aggregate amounts due and
                           payable on such Securities for principal (and premium
                           or Make-Whole Amount, if any), interest and
                           Additional Amounts, respectively, and

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

         SECTION 507.      LIMITATION ON SUITS.

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

         (1)      such Holder has previously given written notice to the Trustee
of a continuing Event of Default with respect to the Securities of that series;

         (2)      the Holders of not less than 25% in principal amount of the
Outstanding Securities of that series shall have made written request to the
Trustee to institute proceedings in respect of such Event of Default in its own
name as Trustee hereunder;

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

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

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

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

         SECTION 508.      UNCONDITIONAL RIGHT OF HOLDERS TO RECEIVE PRINCIPAL,
PREMIUM OR MAKE-WHOLE AMOUNT, IF ANY, INTEREST AND ADDITIONAL AMOUNTS.

         Notwithstanding any other provision in this Indenture, the Holder of
any Security shall have the right which is absolute and unconditional to receive
payment of the principal of (and premium or Make-Whole Amount, if any) and
(subject to Sections 305 and 307) interest on, and any Additional Amounts in
respect of, such Security on the due date expressed in such Security (or, in the
case of redemption, on the Redemption Date), to convert or exchange such
Securities in accordance with Article Sixteen and to institute suit for the
enforcement of any such payment, and such rights shall not be impaired without
the consent of such Holder.

         SECTION 509.      RESTORATION OF RIGHTS AND REMEDIES.

                                      -38-

<PAGE>

         If the Trustee or any Holder of a Security has instituted any
proceeding to enforce any right or remedy under this Indenture or any Security
Guarantee 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 the Company, the Security Guarantors, the Trustee and the
Holders of Securities shall, subject to any determination in such proceeding, 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 has been instituted.

         SECTION 510.      RIGHTS AND REMEDIES CUMULATIVE.

         Except as otherwise provided with respect to the replacement or payment
of mutilated, destroyed, lost or stolen Securities in the last paragraph of
Section 306, no right or remedy herein conferred upon or reserved to the Trustee
or to the Holders of Securities 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 Security to
exercise any right or remedy accruing upon any Event of Default shall impair any
such right or remedy or constitute a waiver of any such Event of Default or any
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 of Securities, as
the case may be.

         SECTION 512.      CONTROL BY HOLDERS OF SECURITIES.

         The Holders of not less than a majority in principal amount of the
Outstanding Securities of any series shall have the right to direct the time,
method and place of conducting any proceeding for any remedy available to the
Trustee or exercising any trust or power conferred on the Trustee with respect
to the Securities of such series, provided that

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

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

         (3)      the Trustee need not take any action which might involve it in
personal liability or be unduly prejudicial to the Holders of Securities of such
series not joining therein (but the Trustee shall have no obligation as to the
determination of such undue prejudice).

                                      -39-

<PAGE>

         SECTION 513.      WAIVER OF PAST DEFAULTS.

         The Holders of not less than a majority in principal amount of the
Outstanding Securities of any series may on behalf of the Holders of all the
Securities of such series consent to the waiver of any past default hereunder
with respect to such series and its consequences, except a default

         (1)      in the payment of the principal of (or premium or Make-Whole
Amount, if any) or interest on or Additional Amounts payable in respect of any
Security of such series, 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 Security of such series affected.

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

         SECTION 514.      WAIVER OF STAY OR EXTENSION LAWS.

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

         SECTION 515.      UNDERTAKING FOR COSTS.

         All parties to this Indenture agree, and each Holder of any Security by
his acceptance thereof shall be deemed to have agreed, that any court may in its
discretion require, in any suit for the enforcement of any right or remedy under
this Indenture or any Security Guarantee, or in any suit against the Trustee for
any action taken or omitted by it as Trustee, the filing by any party litigant
in such suit of an undertaking to pay the costs of such suit, and that such
court may in its discretion assess reasonable costs, including reasonable
attorneys' fees, against any party litigant in such suit having due regard to
the merits and good faith of the claims or defenses made by such party litigant;
but the provisions of this Section shall not apply to any suit instituted by the
Trustee, to any suit instituted by any Holder, or group of Holders, holding in
the aggregate more than 10% in principal amount of the Outstanding Securities,
or to any suit instituted by any Holder for the enforcement of the payment of
the principal of (or premium or Make-Whole Amount, if any) or interest on or
Additional Amounts payable with respect to any Security on or

                                      -40-

<PAGE>

after the respective Stated Maturities expressed in such Security (or in the
case of redemption, on or after the Redemption Date) or to enforce the right to
convert or exchange any Security in accordance with Article Sixteen.

                                   ARTICLE SIX

                                   THE TRUSTEE

         SECTION 601.      NOTICE OF DEFAULTS.

         Within 90 days after the occurrence of any default hereunder actually
known to a Responsible Officer of the Trustee with respect to the Securities of
any series, the Trustee shall transmit in the manner and to the extent provided
in TIA Section 313(c), notice of such default hereunder, 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 or Make-Whole Amount,
if any) or interest on or any Additional Amounts with respect to any Security of
such series, or in the payment of any sinking fund installment with respect to
the Securities of such series, the Trustee shall be protected in withholding
such notice if and so long as Responsible Officers of the Trustee in good faith
determine that the withholding of such notice is in the interests of the Holders
of the Securities of such series; and provided further that in the case of any
default or breach of the character specified in Section 501(4) with respect to
the Securities of such series, no such notice to Holders shall be given until at
least 60 days after the occurrence thereof, unless such default shall have been
cured or waived. For the purpose of this Section, the term "default" means any
event which is, or after notice or lapse of time or both would become, an Event
of Default with respect to the Securities of such series.

         SECTION 602.      CERTAIN RIGHTS OF TRUSTEE.

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

         (1)      the Trustee shall perform only such duties as are expressly
undertaken by it to perform under this Indenture and no implied covenants or
obligations shall be read into this Indenture against the Trustee;

         (2)      the Trustee may conclusively rely and shall be fully protected
in acting or refraining from acting upon any resolution, certificate, statement,
instrument, opinion, report, notice, request, direction, consent, order, bond,
debenture, note, coupon or other paper or document believed by it to be genuine
and to have been signed or presented by the proper party or parties;

         (3)      any request or direction of the Company mentioned herein shall
be sufficiently evidenced by a Company Request or Company Order (other than
delivery of any Security to the Trustee for authentication and delivery pursuant
to Section 303 which shall be sufficiently evidenced as provided therein) and
any resolution of the Board of Directors may be sufficiently evidenced by a
Board Resolution;

                                      -41-

<PAGE>

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

         (5)      the Trustee may consult with counsel and as a condition to the
taking, suffering or omission of any action hereunder may demand an Opinion of
Counsel, and the 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;

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

         (7)      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, coupon 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 or any Security Guarantor, personally or by
agent or attorney;

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

         (9)      the Trustee shall not be liable for any action taken, suffered
or omitted by it in good faith and reasonably believed by it to be authorized or
within the discretion or rights or powers conferred upon it by this Indenture or
any Security Guarantee. The Trustee shall not be required to expend or risk its
own funds or otherwise incur any financial liability in the performance of any
of its duties hereunder, or in the exercise of any of its rights or powers, if
it shall have reasonable grounds for believing that repayment of such funds or
indemnity satisfactory to the Trustee against such risk or liability is not
reasonably assured to it;

         (10)     the Trustee shall not be deemed to have knowledge of any
default or Event of Default or fact or event which might require the Trustee to
take (or refrain from taking) any action or give any notice unless one of its
Responsible Officers has actual knowledge thereof;

         (11)     whether or not therein expressly provided, this Section shall
govern every provision of this Indenture that in any way relates to the Trustee;

                                      -42-

<PAGE>

         (12)     delivery of any reports, information and documents to the
Trustee pursuant to Sections 703 and 1008 hereof is for informational purposes
only and the Trustee's receipt of such shall not constitute notice of any
information contained therein or determinable from information contained
therein, including the Company's compliance with any of its covenants hereunder
(as to which the Trustee is entitled to rely exclusively on the certificate
delivered under Section 1009 hereof;

         (13)     the rights, privileges, immunities and benefits given to the
Trustee hereunder, including without limitation, its right to be indemnified,
are extended to, and shall be enforceable by, the Trustee in each of its
capacities hereunder, and to each agent, custodian and other Person employed by
the Trustee consistent with the terms of this Indenture to act hereunder; and

         (14)     any permissive right or authority granted to the Trustee shall
not be construed as a mandatory duty.

         SECTION 603.      NOT RESPONSIBLE FOR RECITALS OR ISSUANCE OF
SECURITIES.

         The recitals contained herein and in the Securities and the Security
Guarantees, except the Trustee's certificate of authentication, shall be taken
as the statements of the Company and the Security Guarantors, as the case may
be, and neither the Trustee nor any Authenticating Agent assumes any
responsibility for their correctness. The Trustee makes no representations as to
the validity or sufficiency of this Indenture, any Security Guarantee or of the
Securities, except that the Trustee represents that it is duly authorized to
execute and deliver this Indenture and the Security Guarantees, authenticate the
Securities and perform its obligations hereunder. Neither the Trustee nor any
Authenticating Agent shall be accountable for the use or application by the
Company or any Security Guarantor of Securities or the proceeds thereof.

         SECTION 604.      MAY HOLD SECURITIES.

         The Trustee, any Paying Agent, Security Registrar, Authenticating Agent
or any other agent of the Company, in its individual or any other capacity, may
become the owner or pledgee of Securities and, subject to Section 613 and TIA
Sections 310(b) and 311, may otherwise deal with the Company and any Security
Guarantor with the same rights it would have if it were not Trustee, Paying
Agent, Security Registrar, Authenticating Agent or such other agent.

         SECTION 605.      MONEY HELD IN TRUST.

         Money held by the Trustee in trust hereunder need not be segregated
from other funds except to the extent required by law. The Trustee shall be
under no liability for interest on, or investment of, any money received by it
hereunder.

         SECTION 606.      COMPENSATION AND REIMBURSEMENT.

         The Company agrees:

                                      -43-

<PAGE>

         (1)      to pay to the Trustee from time to time reasonable
compensation for all services rendered by it hereunder, including extraordinary
services rendered in connection with or during the continuation of a default
hereunder (which compensation shall not be limited by any provision of law in
regard to the compensation of a trustee of an express trust);

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

         (3)      to indemnify each of the Trustee and any predecessor Trustee
and each of their respective directors, officers, agents and employees for, and
to hold each of them harmless against, any loss, liability or expense, arising
out of or in connection with the acceptance or administration of the trust or
trusts or the performance of its duties hereunder, 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 except to
the extent any such loss, liability or expense may be attributable to its own
gross negligence or bad faith.

         As security for the performance of the obligations of the Company under
this Section, the Trustee shall have a lien prior to the Securities upon all
property and funds held or collected by the Trustee as such, except funds held
in trust for the payment of principal of (or premium or Make-Whole Amount, if
any) or interest on particular Securities.

         When the Trustee incurs expenses or renders services in connection with
an Event of Default described in Section 501(7) and (8), such expenses
(including the fees and expenses of its counsel) and the compensation for such
services are intended to constitute expenses of administration under any
Bankruptcy Law.

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

         SECTION 607.      CORPORATE TRUSTEE REQUIRED; ELIGIBILITY.

         There shall at all times be 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 $50,000,000 or is a subsidiary of a corporation which
shall be a Person that has a combined capital and surplus of at least
$50,000,000 and which unconditionally guarantees the obligations of the Trustee
hereunder. If such Trustee or Person publishes reports of condition at least
annually, pursuant to law or 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 Trustee or Person
shall be deemed to be its combined capital and surplus as set forth in its most
recent report of condition so published. If at any time the Trustee shall cease
to be eligible in accordance with the provisions of this Section, it shall
resign immediately in the manner and with the effect hereinafter specified in
this Article.

                                      -44-

<PAGE>

         SECTION 608.      RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR.

         (a)      No resignation or removal of the Trustee and no appointment of
a successor Trustee pursuant to this Article shall become effective until the
acceptance of appointment by the successor Trustee in accordance with the
applicable requirements of Section 609.

         (b)      The Trustee may resign at any time with respect to the
Securities of one or more series by giving written notice thereof to the
Company. If an instrument of acceptance by a successor Trustee 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 with respect to the
Securities of any series by Act of the Holders of a majority in principal amount
of the Outstanding Securities of such series delivered to the Trustee and to the
Company.

         (d)      If at any time:

                  (1)      the Trustee shall fail to comply with the provisions
         of Section 613 or TIA Section 310(b) after written request therefor by
         the Company or by any Holder of a Security who has been a bona fide
         Holder of a Security 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 of a Security who has been a bona fide Holder
         of a Security 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 or pursuant to a Board Resolution may
remove the Trustee and appoint a successor Trustee with respect to all
Securities, or (ii) subject to TIA Section 315(e), any Holder of a Security who
has been a bona fide Holder of a Security for at least six months may, on behalf
of himself and all others similarly situated, petition any court of competent
jurisdiction for the removal of the Trustee with respect to all Securities and
the appointment of a successor Trustee or Trustees.

         (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 with
respect to the Securities of one or more series, the Company, by or pursuant to
a Board Resolution, shall promptly appoint a successor Trustee or Trustees with
respect to the Securities of that or those series (it being understood that any
such successor Trustee may be appointed with respect to the Securities of one or
more or all of such series and that at any time there shall be only one Trustee
with respect to the Securities of any particular series). If, within one year
after such resignation, removal or incapability, or the occurrence of such
vacancy, a successor Trustee with respect to the Securities

                                      -45-

<PAGE>

of any series shall be appointed by Act of the Holders of a majority in
principal amount of the Outstanding Securities of such series 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
with respect to the Securities of such series and to that extent supersede the
successor Trustee appointed by the Company. If no successor Trustee with respect
to the Securities of any series shall have been so appointed by the Company or
the Holders of Securities and accepted appointment in the manner hereinafter
provided, any Holder of a Security who has been a bona fide Holder of a Security
of such series 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 with respect to Securities of such series.

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

         SECTION 609.      ACCEPTANCE OF APPOINTMENT BY SUCCESSOR.

         (a)      In case of the appointment hereunder of a successor Trustee
with respect to all Securities, every such successor Trustee 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, subject nevertheless to its
claim, if any, provided for in Section 606.

         (b)      In case of the appointment hereunder of a successor Trustee
with respect to the Securities of one or more (but not all) series, the Company,
the retiring Trustee and each successor Trustee with respect to the Securities
of one or more series shall execute and deliver an indenture supplemental
hereto, pursuant to Article Nine hereof, wherein each successor Trustee shall
accept such appointment and which (1) shall contain such provisions as shall be
necessary or desirable to transfer and confirm to, and to vest in, each
successor Trustee all the rights, powers, trusts and duties of the retiring
Trustee with respect to the Securities of that or those series to which the
appointment of such successor Trustee relates, (2) if the retiring Trustee is
not retiring with respect to all Securities, shall contain such provisions as
shall be deemed necessary or desirable to confirm that all the rights, powers,
trusts and duties of the retiring Trustee with respect to the Securities of that
or those series as to which the retiring Trustee is not retiring shall continue
to be vested in the retiring Trustee, and (3) shall add to or change any of the
provisions of this Indenture as shall be necessary to provide for or facilitate
the administration of the trusts hereunder by more than one Trustee, it being
understood that nothing herein or in such supplemental indenture shall
constitute such Trustees co-trustees of the same trust and that each such
Trustee shall be trustee of a trust or trusts hereunder separate and apart from
any trust or

                                      -46-

<PAGE>

trusts hereunder administered by any other such Trustee; and upon the execution
and delivery of such supplemental indenture the resignation or removal of the
retiring Trustee shall become effective to the extent provided therein and each
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 with respect to the Securities of that or those series to which the
appointment of such successor Trustee relates; but, on request of the Company or
any successor Trustee, such retiring Trustee shall duly assign, transfer and
deliver to such successor Trustee all property and money held by such retiring
Trustee hereunder with respect to the Securities of that or those series to
which the appointment of such successor Trustee relates.

         (c)      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 referred
to in paragraph (a) or (b) of this Section, as the case may be.

         (d)      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.

         (e)      All monies due and owing to the Trustee shall be paid before
the Successor Trustee takes over.

         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 Securities shall have been
authenticated, but not delivered, by the Trustee then in office, any successor
by merger, conversion or consolidation to such authenticating Trustee may adopt
such authentication and deliver the Securities so authenticated with the same
effect as if such successor Trustee had itself authenticated such Securities. In
case any Securities shall not have been authenticated by such predecessor
Trustee, any such successor Trustee may authenticate and deliver such
Securities, in either its own name or that of its predecessor Trustee, with the
full force and effect which this Indenture provides for the certificate of
authentication of the Trustee.

         SECTION 611.      APPOINTMENT OF AUTHENTICATING AGENT.

         At any time when any of the Securities remain Outstanding, the Trustee
may appoint an Authenticating Agent or Agents with respect to one or more series
of Securities which shall be authorized to act on behalf of the Trustee to
authenticate Securities of such series issued upon exchange, registration of
transfer or partial redemption or repayment thereof or pursuant to Section 306,
and Securities so authenticated shall be entitled to the benefits of this
Indenture and shall be valid and obligatory for all purposes as if authenticated
by the Trustee hereunder. Any such appointment shall be evidenced by an

of the Trustee, a copy of which instrument shall be promptly furnished to the
Company. Wherever reference is made in this Indenture to the authentication and
delivery of Securities by the Trustee or the Trustee's certificate of
authentication, such reference shall be deemed to include authentication and
delivery on behalf of the Trustee by an Authenticating Agent and a certificate
of authentication executed on behalf of the Trustee by an Authenticating Agent.
Each Authenticating Agent shall be reasonably acceptable to the Company and,
except as may otherwise be provided pursuant to Section 301, shall at all times
be a bank or trust company or corporation organized and doing business and in
good standing under the laws of the United States of America or of any State or
the District of Columbia, authorized under such laws to act as Authenticating
Agent, having a combined capital and surplus of not less than $25,000,000 and
subject to supervision or examination by Federal or State authorities. If such
Authenticating Agent publishes reports of condition at least annually, pursuant
to law or the requirements of the aforesaid supervising or examining authority,
then for the purposes of this Section, the combined capital and surplus of such
Authenticating Agent shall be deemed to be its combined capital and surplus as
set forth in its most recent report of condition so published. In case at any
time an Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, such Authenticating Agent shall resign immediately
in the manner and with the effect specified in this Section.

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

         An Authenticating Agent for any series of Securities may at any time
resign by giving written notice of resignation to the Trustee for such series
and to the Company. The Trustee for any series of Securities may at any time
terminate the agency of an Authenticating Agent by giving written notice of
termination to such Authenticating Agent and to the Company. Upon receiving such
a notice of resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, the Trustee for such series may appoint a successor
Authenticating Agent which shall be acceptable to the Company and shall give
notice of such appointment to all Holders of Securities of or within the series
with respect to which such Authenticating Agent will serve in the manner set
forth in Section 106. Any successor Authenticating Agent upon acceptance of its
appointment hereunder shall become vested with all the rights, powers and duties
of its predecessor hereunder, with like effect as if originally named as an
Authenticating Agent herein. No successor Authenticating Agent shall be
appointed unless eligible under the provisions of this Section.

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

                                      -48-

         If an appointment with respect to one or more series is made pursuant
to this Section, the Securities of such series may have endorsed thereon, in
addition to or in lieu of the Trustee's certificate of authentication, an
alternate certificate of authentication substantially in the following form:

         This is one of the Securities of the series designated therein referred
to in the within-mentioned Indenture.

                                    [_________________], as Trustee

                                    By:   ___________________________
                                          as Authenticating Agent

                                    By:   ___________________________
                                          Authorized Officer

         SECTION 612.      CERTAIN DUTIES AND RESPONSIBILITIES.

         No provision of this Indenture or any Security Guarantee shall require
the Trustee to expend or risk its own funds or otherwise incur any financial
liability in the performance of any of its duties hereunder, or in the exercise
of any of its rights or powers, if it shall have reasonable grounds for
believing that repayment of such funds or indemnity satisfactory to the Trustee
against such risk or liability is not reasonably assured to it. Whether or not
therein expressly so provided, every provision of this Indenture and any
Security Guarantee relating to the conduct or affecting the liability of or
affording protection to the Trustee shall be subject to the provisions of this
Section.

         SECTION 613.      CONFLICTING INTERESTS.

         If the Trustee has or shall acquire a conflicting interest within the
meaning of the Trust Indenture Act, the Trustee shall either eliminate such
interest or resign, to the extent and in the manner provided by, and subject to
the provisions of, the Trust Indenture Act and this Indenture. To the extent
permitted by such Act, the Trustee shall not be deemed to have a conflicting
interest by virtue of being a trustee under this Indenture with respect to
Securities of more than one series. In case an Event of Default shall occur and
be continuing, the Trustee shall exercise such of its rights and powers under
the applicable 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 own affairs.

         The Trustee may be appointed, and may serve contemporaneously with its
service hereunder, as trustee under an Indenture among the Company, the Senior
Guarantors and it providing for issuance by the Company of debt instruments
subordinated to the Securities (the "Subordinated Indenture") and shall not be
considered to be conflicted in its duties under either the Subordinated
Indenture or this Indenture by reason of its acting as trustee under the other.
After an Event of Default (as defined in the respective Indentures) under either
Indenture and in order that it might not be conflicted in the performance of its
duties under either Indenture, the

                                      -49-

<PAGE>

Trustee shall resign as trustee under one of the Indentures; provided, however,
that until the appointment of a successor Trustee, the Trustee shall not be
considered to have violated the standard set forth in Section 7.01(a) hereof by
continuing to act as Trustee under both the Subordinated Indenture and this
Indenture if it separates the performance of its discretionary duties under the
Subordinated Indenture and this Indenture within its corporate trust department
and retains separate counsel for itself as trustee under each of such
Indentures.

with the Company and the Trustee that neither the Company nor the Trustee nor
any Authenticating Agent nor any Paying Agent nor any Security Registrar nor any

reason of the disclosure of any information as to the names and addresses of the

any of the foregoing as the Commission may from time to time by rules and
regulations prescribe) which the Company may be required to file with the
Commission pursuant to Section 13 or Section 15(d) of the Exchange Act; or, if
the Company is not required to file information, documents or reports pursuant
to either of such Sections, then it will file with the Trustee and the

reports required to be filed by the Company pursuant to paragraphs (1) or (2) of
this Section as may be required by rules and regulations prescribed from time to

Date for interest for each series of Securities, a list, in such form as the
Trustee may reasonably require, of the names and addresses of the Holders of
Registered Securities of such series as of such Regular Record Date, or if there
is no Regular Record Date for interest for such series of Securities,
semi-annually, upon such dates as are set forth in the Board Resolution or
indenture supplemental hereto authorizing such series, and

         (b)      at such other times as the Trustee may request in writing,
within 30 days after the receipt by the Company of any such request, a list of
similar form and content as of a date not more than 15 days prior to the time

provided, however, that, so long as the Trustee is the Security Registrar, no
such lists shall be required to be furnished.

                                  ARTICLE EIGHT

                CONSOLIDATION, MERGER, SALE, LEASE OR CONVEYANCE

         SECTION 801.      CONSOLIDATIONS AND MERGERS OF COMPANY AND SALES,
LEASES AND CONVEYANCES PERMITTED SUBJECT TO CERTAIN CONDITIONS.

         The Company may consolidate with, or sell, lease or convey all or
substantially all of its assets to, or merge with or into any other Person,
provided that in any such case, (i) either the Company shall be the continuing
entity, or the successor (if other than the Company) entity shall be a Person
organized and existing under the laws of the United States or a State thereof
and such successor entity shall expressly assume the due and punctual payment of
the principal of (and premium or Make-Whole Amount, if any) and any interest
(including all Additional Amounts, if any, payable pursuant to Section 1010) on
all of the Securities, according to their tenor, the conversion or exchange
rights shall be provided for in accordance with Article Sixteen, if applicable,
or as otherwise specified pursuant to Section 301, and the due and punctual

                                      -51-

<PAGE>

performance and observance of all of the covenants and conditions of this
Indenture to be performed by the Company by supplemental indenture, complying
with Article Nine hereof, reasonably satisfactory to the Trustee, executed and
delivered to the Trustee by such Person and (ii) immediately after giving effect
to such transaction and treating any indebtedness which becomes an obligation of
the Company or any Subsidiary as a result thereof as having been incurred by the
Company or such Subsidiary at the time of such transaction, no Event of Default,
and no event which, after notice or the lapse of time, or both, would become an
Event of Default, shall have occurred and be continuing.

         SECTION 802.      RIGHTS AND DUTIES OF SUCCESSOR CORPORATION.

         In case of any such consolidation, merger, sale, lease or conveyance
and upon any such assumption by the successor entity, such successor entity
shall succeed to and be substituted for the Company, with the same effect as if
it had been named herein as the party of the first part, and the predecessor
entity, except in the event of a lease, shall be relieved of any further
obligation under this Indenture and the Securities. Such successor entity
thereupon may cause to be signed, and may issue either in its own name or in the
name of the Company, any or all of the Securities issuable hereunder which
theretofore shall not have been signed by the Company and delivered to the
Trustee; and, upon the order of such successor entity, instead of the Company,
and subject to all the terms, conditions and limitations in this Indenture
prescribed, the Trustee shall authenticate and shall deliver any Securities
which previously shall have been signed and delivered by the officers of the
Company to the Trustee for authentication, and any Securities which such
successor entity thereafter shall cause to be signed and delivered to the
Trustee for that purpose. All the Securities so issued shall in all respects
have the same legal rank and benefit under this Indenture as the Securities
theretofore or thereafter issued in accordance with the terms of this Indenture
as though all of such Securities had been issued at the date of the execution
hereof.

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

         SECTION 803.      OFFICERS' CERTIFICATE AND OPINION OF COUNSEL.

         Any consolidation, merger, sale, lease or conveyance permitted under
Section 801 is also subject to the condition that the Trustee receive an
Officers' Certificate and an Opinion of Counsel to the effect that any such
consolidation, merger, sale, lease or conveyance, and the assumption by any
successor entity, complies with the provisions of this Article and that all
conditions precedent herein provided for relating to such transaction have been
complied with.

<PAGE>

         Without the consent of any Holders of Securities, the Company and the
Security Guarantors, when authorized by or pursuant to a Board Resolution of the
Company and each Security Guarantor, and the Trustee, at any time and from time
to time, may enter into one or more indentures supplemental hereto, in form
satisfactory to the Trustee, for any of the following purposes:

         (1)      to evidence the succession of another Person to the Company or
a Security Guarantor and the assumption by any such successor of the covenants
of the Company or such Security Guarantor herein, in any Security Guarantee and
in the Securities contained; or

         (2)      to add to the covenants of the Company or any Security
Guarantor for the benefit of the Holders of all or any series of Securities
(and, if such covenants are to be for the benefit of less than all series of
Securities, stating that such covenants are expressly being included solely for
the benefit of such series) or to surrender any right or power herein conferred
upon the Company or any Security Guarantor; or

         (3)      to add any additional Events of Default for the benefit of the
Holders of all or any series of Securities (and if such Events of Default are to
be for the benefit of less than all series of Securities, stating that such
Events of Default are expressly being included solely for the benefit of such
series); provided, however, that in respect of any such additional Events of
Default such supplemental indenture may provide for a particular period of grace
after default (which period may be shorter or longer than that allowed in the
case of other defaults) or may provide for an immediate enforcement upon such
default or may limit the remedies available to the Trustee upon such default or
may limit the right of the Holders of a majority in aggregate principal amount
of that or those series of Securities to which such additional Events of Default
apply to waive such default; or

         (4)      to permit or facilitate the issuance of Securities in
uncertificated form, provided that any such action shall not adversely affect
the interests of the Holders of Securities of any series in any material
respect; or

         (5)      to add to, change or eliminate any of the provisions of this
Indenture or any Security Guarantee in respect of any series of Securities,
provided that any such addition, change or elimination shall (i) neither (A)
apply to any Security of any series created prior to the execution of such
supplemental indenture and entitled to the benefit of such provision, nor (B)
modify the rights of the Holder of any such Security with respect to such
provision; or (ii) become effective only when there is no Security Outstanding;
or

         (6)      to secure the Securities; or

         (7)      to establish the form or terms of Securities of any series as
permitted by Sections 201 and 301, including the provisions and procedures
relating to Securities convertible into or exchangeable for other securities or
property of the Company; or

         (8)      to evidence and provide for the acceptance of appointment
hereunder by a successor Trustee with respect to the Securities of one or more
series and to add to or change any

                                      -53-

<PAGE>

of the provisions of this Indenture or any Security Guarantee as shall be
necessary to provide for or facilitate the administration of the trusts
hereunder by more than one Trustee; or

         (9)      to make provision with respect to the conversion or exchange
rights of Holders pursuant to the requirements of Article Sixteen, including
providing for the conversion or exchange of the Securities into any security or
property of the Company; or

         (10)     to cure any ambiguity, to correct or supplement any provision
herein or in any Security Guarantee which may be defective or inconsistent with
any other provision herein or therein, or to make any other provisions with
respect to matters or questions arising under this Indenture or any Security
Guarantee which shall not be inconsistent with the provisions of this Indenture
or such Security Guarantee or to make any other changes, provided that in each
case, such provisions shall not adversely affect the interests of the Holders of
Securities of any series in any material respect; or

         (11)     to close this Indenture with respect to the authentication and
delivery of additional series of Securities or to qualify, or maintain
qualification of, this Indenture under the TIA; or

         (12)     to supplement any of the provisions of this Indenture or any
Security Guarantee to such extent as shall be necessary to permit or facilitate
the defeasance and discharge of any series of Securities pursuant to Sections
401, 1402 and 1403; provided in each case that any such action shall not
adversely affect the interests of the Holders of Securities of such series or
any other series of Securities in any material respect.

         SECTION 902.      SUPPLEMENTAL INDENTURES WITH CONSENT OF HOLDERS.

         With the consent of the Holders of not less than a majority in
principal amount of all Outstanding Securities affected by such supplemental
indenture, by Act of said Holders delivered to the Company and the Trustee, the
Company and each Security Guarantor, when authorized by or pursuant to a Board
Resolution, and the Trustee may enter into an indenture or indentures
supplemental hereto for the purpose of adding any provisions to or changing in
any manner or eliminating any of the provisions of this Indenture or any
Security Guarantee or of modifying in any manner the rights of the Holders of
Securities under this Indenture; provided, however, that no such supplemental
indenture shall, without the consent of the Holder of each Outstanding Security
affected thereby:

         (1)      change the Stated Maturity of the principal of (or premium or
Make-Whole Amount, if any, on) or any installment of principal of or interest
on, any Security; or reduce the principal amount thereof or the rate or amount
of interest thereon or any Additional Amounts payable in respect thereof, or any
premium or Make-Whole Amount payable upon the redemption thereof, or change any
obligation of the Company to pay Additional Amounts pursuant to Section 1010
(except as contemplated by Section 801(i) and permitted by Section 901(1)), or
reduce the amount of the principal of an Original Issue Discount Security or
Make-Whole Amount, if any, that would be due and payable upon a declaration of
acceleration of the Maturity thereof pursuant to Section 502 or the amount
thereof provable in bankruptcy pursuant to Section 504, or adversely affect any
right of repayment at the option of the Holder of any

                                      -54-

<PAGE>

Security, or change any Place of Payment where, or the currency or currencies,
currency unit or units or composite currency or currencies in which, the
principal of any Security or any premium or Make-Whole Amount or any Additional
Amounts payable in respect thereof or the interest thereon is payable, or impair
the right to institute suit for the enforcement of any such payment on or after
the Stated Maturity thereof (or, in the case of redemption or repayment at the
option of the Holder, on or after the Redemption Date or the Repayment Date, as
the case may be); or

         (2)      reduce the percentage in principal amount of the Outstanding
Securities of any series, the consent of whose Holders is required for any such
supplemental indenture, or the consent of whose Holders is required for any
waiver with respect to such series (or compliance with certain provisions of
this Indenture or certain defaults hereunder and their consequences) provided
for in this Indenture, or reduce the requirements of Section 1504 for quorum or
voting; or

         (3)      modify any of the provisions of this Section, Section 513 or
Section 1011, except to increase the required percentage to effect such action
or to provide that certain other provisions of this Indenture cannot be modified
or waived without the consent of the Holder of each Outstanding Security
affected thereby; or make any change that adversely affects the right to convert
or exchange any Security as provided in Article Sixteen or pursuant to Section
301 (except as permitted by Section 901(9) or decrease the conversion or
exchange rate or increase the conversion or exchange price of any such Security;
or

         (4)      make any change that adversely affects the right to convert or
exchange any Security as provided in Article Sixteen or pursuant to Section 301
(except as permitted by Section 901(9)) or decrease the conversion or exchange
rate or increase the conversion or exchange price of any such Security; or

         (5)      release any Security Guarantor from any of its obligations
under its Security Guarantee or this Indenture otherwise than in accordance with
this Indenture.

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

         A supplemental indenture which changes or eliminates any covenant or
other provision of this Indenture or any Security Guarantee which has expressly
been included for the benefit of one or more particular series of Securities, or
which modifies the rights of the Holders of Securities of such series with
respect to such covenant or other provision, shall be deemed not to affect the
rights under this Indenture or such Security Guarantee of the Holders of
Securities of any other series.

         SECTION 903.      EXECUTION OF SUPPLEMENTAL INDENTURES.

         In executing, or accepting the additional trusts created by, any
supplemental indenture permitted by this Article or the modification thereby of
the trusts created by this Indenture, the Trustee shall be entitled to receive,
and shall be fully protected in relying upon, an Opinion of

                                      -55-

<PAGE>

Counsel and an Officer's Certificate stating that the execution of such
supplemental indenture is authorized or permitted by this Indenture and that all
conditions precedent to the execution of such supplemental indenture have been

such supplemental indenture which affects the Trustee's own rights, duties or
immunities under this Indenture or otherwise.

         SECTION 904.      EFFECT OF SUPPLEMENTAL INDENTURES.

         Upon the execution of any supplemental indenture under this Article,
this Indenture and/or the applicable Security Guarantee shall be modified in
accordance therewith, and such supplemental indenture shall form a part of this
Indenture and/or the applicable Security Guarantee for all purposes; and every
Holder of Securities theretofore or thereafter authenticated and delivered
hereunder shall be bound thereby.

         SECTION 905.      CONFORMITY WITH TRUST INDENTURE ACT.

         Every supplemental indenture executed pursuant to this Article shall
conform to the requirements of the Trust Indenture Act as then in effect.

         SECTION 906.      REFERENCE IN SECURITIES TO SUPPLEMENTAL INDENTURES.

         Securities of any series authenticated and delivered after the
execution of any supplemental indenture pursuant to this Article may, and shall
if required by the Trustee, bear a notation in form approved by the Trustee as
to any matter provided for in such supplemental indenture. If the Company shall
so determine, new Securities of any series so modified as to conform, in the
opinion of the Trustee and the Company, to any such supplemental indenture may
be prepared and executed by the Company and authenticated and delivered by the
Trustee in exchange for Outstanding Securities of such series.

         SECTION 907.      NOTICE OF SUPPLEMENTAL INDENTURES.

         Promptly after the execution by the Company and the Trustee of any
supplemental indenture pursuant to the provisions of Section 902, the Company
shall give notice thereof to the Holders of each Outstanding Security affected,
in the manner provided for in Section 106, setting forth in general terms the
substance of such supplemental indenture.

                                   ARTICLE TEN

                                    COVENANTS

         SECTION 1001.     PAYMENT OF PRINCIPAL, PREMIUM OR MAKE-WHOLE AMOUNT,
IF ANY, INTEREST AND ADDITIONAL AMOUNTS.

         The Company covenants and agrees for the benefit of the Holders of each
series of Securities that it will duly and punctually pay the principal of (and
premium or Make-Whole Amount, if any) and interest on and any Additional Amounts
payable in respect of the Securities

                                      -56-

<PAGE>

of that series in accordance with the terms of such series of Securities and
this Indenture. Unless otherwise specified with respect to Securities of any
series pursuant to Section 301, at the option of the Company, all payments of
principal may be paid by check to the registered Holder of the Registered
Security or other person entitled thereto against surrender of such Security.

         SECTION 1002.     MAINTENANCE OF OFFICE OR AGENCY.

         If Securities of a series are issuable only as Registered Securities,
the Company shall maintain in each Place of Payment for any series of Securities
an office or agency where Securities of that series may be presented or
surrendered for payment or conversion, where Securities of that series may be
surrendered for registration of transfer or exchange, where Securities of that
series may be converted or exchanged in accordance with Article Sixteen, and
where notices and demands to or upon the Company and each Security Guarantor in
respect of the Securities of that series and this Indenture and any Security
Guarantee may be served. 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 its agent to receive all such presentations, surrenders,
notices and demands.

         The Company may from time to time designate one or more other offices
or agencies where the Securities of one or more series may be presented or
surrendered for any or all of such purposes, and may from time to time rescind
such designations; provided, however, that no such designation or rescission
shall in any manner relieve the Company of its obligation to maintain an office
or agency in accordance with the requirements set forth above for Securities of
any series for such purposes. The Company will give prompt written notice to the
Trustee of any such designation or rescission and of any change in the location
of any such other office or agency.

         Unless otherwise specified with respect to any Securities pursuant to
Section 301, if and so long as the Securities of any series (i) are denominated
in a Foreign Currency or (ii) may be payable in a Foreign Currency, or so long
as it is required under any other provision of the Indenture, then the Company
will maintain with respect to each such series of Securities, or as so required,
at least one exchange rate agent.

         SECTION 1003.     MONEY FOR SECURITIES PAYMENTS TO BE HELD IN TRUST.

         If the Company shall at any time act as its own Paying Agent with
respect to any series of any Securities, it will, on or before each due date of
the principal of (and premium or Make-Whole Amount, if any), or interest on or
Additional Amounts in respect of, any of the Securities of that series,
segregate and hold in trust for the benefit of the Persons entitled thereto a
sum in the currency or currencies, currency unit or units or composite currency
or currencies in which the Securities of such series are payable (except as
otherwise specified pursuant to Section 301 for the Securities of such series)
sufficient to pay the principal (and premium or Make-Whole Amount, if any) or
interest or Additional Amounts so becoming due until such sums shall be paid to
such Persons or otherwise disposed of as herein provided, and will promptly
notify the Trustee of its action or failure so to act.

                                      -57-

<PAGE>

         Whenever the Company shall have one or more Paying Agents for any
series of Securities, it will, on or before each due date of the principal of
(and premium or Make-Whole Amount, if any), or interest on or Additional Amounts
in respect of, any Securities of that series, deposit with a Paying Agent a sum
(in the currency or currencies, currency unit or units or composite currency or
currencies described in the preceding paragraph) sufficient to pay the principal
(and premium or Make-Whole Amount, if any) or interest or Additional Amounts, so
becoming due, such sum to be held in trust for the benefit of the Persons
entitled to such principal, premium, Make-Whole Amount or interest or Additional
Amounts and (unless such Paying Agent is the Trustee) the Company will promptly
notify the Trustee of its action or failure so to act.

         The Company will cause each Paying Agent other than the Trustee to
execute and deliver to the Trustee an instrument in which such Paying Agent
shall agree with the Trustee, subject to the provisions of this Section, that
such Paying Agent will:

         (1)      hold all sums held by it for the payment of principal of (and
premium or Make-Whole Amount, if any) or interest on Securities or Additional
Amounts 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 written notice of any default by the Company,
any Security Guarantor (or any other obligor upon the Securities) in the making
of any such payment of principal (and premium or Make-Whole Amount, if any) or
interest or Additional Amounts; 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 trusts as those upon which such sums were held by the Company or
such Paying Agent; and, upon such payment by any Paying Agent to the Trustee,
such Paying Agent shall be released from all further liability with respect to
such sums.

         Except as otherwise provided in the Securities of any series, any money
deposited with the Trustee or any Paying Agent, or then held by the Company, in
trust for the payment of the principal of (and premium or Make-Whole Amount, if
any) or interest on, or any Additional Amounts in respect of, any Security of
any series and remaining unclaimed for two years after such principal (and
premium or Make-Whole Amount, if any), interest or Additional Amounts has become
due and payable shall be paid to the Company upon Company Request or (if then
held by the Company) shall be discharged from such trust; and the Holder of such
Security shall thereafter, as an unsecured general creditor, look only to the
Company for payment of such principal of (and premium or Make-Whole Amount, if
any) or interest on, or any Additional Amounts in respect of, any Security,
without interest thereon, and all liability of the Trustee or such Paying Agent
with respect to such trust money, and all liability of the Company as trustee

                                      -58-

<PAGE>

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 an Authorized Newspaper,
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 will be repaid to the
Company.

         SECTION 1004.     EXISTENCE.

         Subject to Article Eight, the Company will do or cause to be done all
things necessary to preserve and keep in full force and effect the existence,
rights (charter and statutory) and franchises of the Company and its
Subsidiaries; provided, however, that the Company shall not be required to
preserve any 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 of Securities of any
series.

         SECTION 1005.     MAINTENANCE OF PROPERTIES.

         The Company will cause all of its material properties used or useful 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 will cause to be made all necessary repairs, renewals,
replacements, betterments and improvements thereof, all as in the judgment of
the Company may be necessary so that the business carried on in connection
therewith may be properly and advantageously conducted at all times; provided,
however, that nothing in this Section shall prevent the Company or any
Subsidiary from selling or otherwise disposing of its properties in the ordinary
course of its business.

         SECTION 1006.     INSURANCE.

         The Company will, and will cause each of its Subsidiaries to, keep all
its insurable properties insured against loss or damage with commercially
reasonable amounts and types of insurance provided by insurers of recognized
responsibility.

         SECTION 1007.     PAYMENT OF TAXES AND OTHER CLAIMS.

         The Company will pay or discharge or cause to be paid or discharged,
before the same shall become delinquent, (1) all taxes, assessments and
governmental charges levied or imposed upon it or any Subsidiary or upon the
income, profits or property of the Company or any Subsidiary, and (2) all lawful
claims for labor, materials and supplies which, if unpaid, might by law become a
lien upon the property of the Company or any 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 1008.

                                      -59-

<PAGE>

         SECTION 1009.     STATEMENT AS TO COMPLIANCE.

         The Company will deliver to the Trustee within 120 days after the end
of each fiscal year, a brief certificate from the principal executive officer,
principal financial officer or principal accounting officer as to his or her
knowledge of the Company's compliance with all conditions and covenants under
this Indenture and, in the event of any noncompliance, specifying such
noncompliance and the nature and status thereof. For purposes of this Section
1009, such compliance shall be determined without regard to any period of grace
or requirement of notice under this Indenture.

         SECTION 1010.     ADDITIONAL AMOUNTS.

         If any Securities of a series provide for the payment of Additional
Amounts, the Company will pay to the Holder of any Security of such series
Additional Amounts as may be specified as contemplated by Section 301. Whenever
in this Indenture there is mentioned, in any context except in the case of
Section 502(1), the payment of the principal of or any premium, Make-Whole
Amount or interest on, or in respect of, any Security of any series or the net
proceeds received on the sale or exchange of any Security of any series, such
mention shall be deemed to include mention of the payment of Additional Amounts
provided by the terms of such series established pursuant to Section 301 to the
extent that, in such context, Additional Amounts are, were or would be payable
in respect thereof pursuant to such terms and express mention of the payment of
Additional Amounts (if applicable) in any provisions hereof shall not be
construed as excluding Additional Amounts in those provisions hereof where such
express mention is not made.

         Except as otherwise specified as contemplated by Section 301, if the
Securities of a series provide for the payment of Additional Amounts, at least
10 days prior to the first Interest Payment Date with respect to that series of
Securities (or if the Securities of that series will not bear interest prior to
Maturity, the first day on which a payment of principal and any premium is
made), and at least 10 days prior to each date of payment of principal and any
premium or Make-Whole Amount or interest if there has been any change with
respect to the matters set forth in the below-mentioned Officers' Certificate,
the Company will furnish the Trustee and the Company's principal Paying Agent or
Paying Agents, if other than the Trustee, with an Officers' Certificate
instructing the Trustee and such Paying Agent or Paying Agents whether such
payment of principal of and any premium or interest on the Securities of that
series shall be made to Holders of Securities of that series who are not United
States persons without withholding for or on account of any tax, assessment or
other governmental charge described in the Securities of or within the series.
If any such withholding shall be required, then such Officers' Certificate shall
specify by country the amount, if any, required to be withheld on such payments
to such Holders of Securities of that series and the Company will pay to the
Trustee or such Paying Agent the Additional Amounts, if any, required by the
terms of such Securities. In the event that the Trustee or any Paying Agent, as
the case may be, shall not so receive the above mentioned certificate, then the
Trustee or such Paying Agent shall be entitled (i) to assume that no such
withholding or deduction is required with respect to any payment of principal or
interest with

                                      -60-

<PAGE>

respect to any Securities of a series until it shall have received a certificate
advising otherwise and (ii) to make all payments of principal and interest with
respect to the Securities of a series without withholding or deductions until
otherwise advised. The Company covenants to indemnify the Trustee and any Paying
Agent and their respective officers, directors, employees and agents for, and to
hold them harmless against, any loss, liability or expense (including legal fees
and expenses) reasonably incurred without gross negligence or bad faith on their
part arising out of or in connection with actions taken or omitted by any of
them in reliance on any Officers' Certificate furnished pursuant to this Section
or in reliance on the Company's not furnishing such an Officers' Certificate.

         SECTION 1011.     WAIVER OF CERTAIN COVENANTS.

         The Company may omit in any particular instance to comply with any
term, provision or condition set forth in Sections 1004 to 1008, inclusive, and
with any other term, provision or condition with respect to the Securities of
any series specified in accordance with Section 301 (except any such term,
provision or condition which could not be amended without the consent of all
Holders of Securities of such series pursuant to Section 902), if before or
after the time for such compliance the Holders of at least a majority in
principal amount of all outstanding Securities of such series, by Act of such
Holders, either waive such compliance in such instance or generally waive
compliance with such covenant or condition, but no such waiver shall extend to
or affect such covenant or condition except to the extent so expressly waived,
and, until such waiver shall become effective, the obligations of the Company
and the duties of the Trustee in respect of any such term, provision or
condition shall remain in full force and effect.

         SECTION 1012.     SECURITY GUARANTEES.

         Each of the Security Guarantors and the Company will, and the Company
will cause each of the Security Guarantors to, ensure at all times that, unless
otherwise permitted by this Indenture, each Security Guarantee will remain in
full force and effect and shall not be subordinated by written agreement in
right of payment to any indebtedness or other obligations of the Security
Guarantors, unless required by applicable law.

                                 ARTICLE ELEVEN

                            REDEMPTION OF SECURITIES

         SECTION 1101.     APPLICABILITY OF ARTICLE.

         Securities of any series which are redeemable before their Stated
Maturity shall be redeemable in accordance with their terms and (except as
otherwise specified as contemplated by Section 301 for Securities of any series)
in accordance with this Article.

         SECTION 1102.     ELECTION TO REDEEM; NOTICE TO TRUSTEE.

         The election of the Company to redeem any Securities shall be evidenced
by or pursuant to a Board Resolution. In case of any redemption at the election
of the Company of less than all

                                      -61-

<PAGE>

of the Securities of any series, the Company shall, at least 45 days prior to
the giving of the notice of redemption in Section 1104 (unless a shorter notice
shall be satisfactory to the Trustee), notify the Trustee, in writing, of such
Redemption Date and of the principal amount of Securities of such series to be
redeemed. In the case of any redemption of Securities prior to the expiration of
any restriction on such redemption provided in the terms of such Securities or
elsewhere in this Indenture, the Company shall furnish the Trustee with an
Officers' Certificate and Opinion of Counsel evidencing compliance with such
restriction.

         SECTION 1103.     SELECTION BY TRUSTEE OF SECURITIES TO BE REDEEMED.

         If less than all the Securities of any series issued on the same day
with the same terms are to be redeemed, the particular Securities to be redeemed
shall be selected not more than 60 days prior to the Redemption Date by the
Trustee, from the Outstanding Securities of such series issued on such date with
the same terms not previously called for redemption, by such method as the
Trustee shall deem fair and appropriate and which may provide for the selection
for redemption of portions (equal to the minimum authorized denomination for
Securities of that series or any integral multiple thereof) of the principal
amount of Securities of such series of a denomination larger than the minimum
authorized denomination for Securities of that series.

         If any Security selected for partial redemption is converted or
exchanged in part before termination of the conversion or exchange right with
respect to the portion of the Security so selected, the converted or exchanged
portion of such Security shall be deemed (so far as may be) to be the portion
selected for redemption. Securities which have been converted or exchanged
during a selection of Securities to be redeemed shall be treated by the Trustee
as Outstanding for the purposes of such selection. In any case where more than
one Security is registered in the same name, the Trustee in its discretion may
treat the aggregate principal amount so registered as if it were represented by
one Security.

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

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

         SECTION 1104.     NOTICE OF REDEMPTION.

         Notice of redemption shall be given in the manner provided in Section
106, not less than 30 days nor more than 60 days prior to the Redemption Date,
unless a shorter period is specified by the terms of such series established
pursuant to Section 301, to each Holder of Securities to be redeemed, but
failure to give such notice in the manner herein provided to the Holder of any
Security designated for redemption as a whole or in part, or any defect in the
notice to any such Holder, shall not affect the validity of the proceedings for
the redemption of any other such Security or portion thereof.

                                      -62-

<PAGE>

         Any notice that is mailed to the Holders of Registered Securities in
the manner herein provided shall be conclusively presumed to have been duly
given, whether or not the Holder receives the notice.

         All notices of redemption shall state:

         (1)      the Redemption Date;

         (2)      the Redemption Price, accrued interest to the Redemption Date
payable as provided in Section 1106, if any, and Additional Amounts, if any;

         (3)      if less than all Outstanding Securities of any series are to
be redeemed, the identification (and, in the case of partial redemption, the
principal amount) of the particular Security or Securities to be redeemed;

         (4)      in case any Security is to be redeemed in part only, that on
and after the Redemption Date, upon surrender of such Security, the holder will
receive, without a charge, a new Security or Securities of authorized
denominations for the principal amount thereof remaining unredeemed;

         (5)      that on the Redemption Date the Redemption Price and accrued
interest to the Redemption Date payable as provided in Section 1106, if any,
will become due and payable upon each such Security, or the portion thereof, to
be redeemed and, if applicable, that interest thereon shall cease to accrue on
and after said date;

         (6)      the Place or Places of Payment where such Securities maturing
after the Redemption Date are to be surrendered for payment of the Redemption
Price and accrued interest, if any, or for conversion or exchange;

         (7)      that the redemption is for a sinking fund, if such is the
case;

         (8)      the CUSIP number of such Security, if any, provided that
neither the Company nor the Trustee shall have any responsibility for any such
CUSIP number; and

         (9)      if applicable, that a Holder of Securities who desires to
convert or exchange Securities to be redeemed must satisfy the requirements for
conversion or exchange contained in such Securities, the then existing
conversion or exchange price or rate and the date and time when the option to
convert or exchange shall expire and the place or places where such Securities
may be surrendered for conversion or exchange.

         Notice of redemption of Securities to be redeemed 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 1105.     DEPOSIT OF REDEMPTION PRICE.

                                      -63-

<PAGE>

         On or 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, which it may not do in the case of a sinking fund payment under Article
Twelve, segregate and hold in trust as provided in Section 1003) an amount of
money in the currency or currencies, currency unit or units or composite
currency or currencies in which the Securities of such series are payable
(except as otherwise specified pursuant to Section 301 for the Securities of
such series) sufficient to pay on the Redemption Date the Redemption Price of,
and (except if the Redemption Date shall be an Interest Payment Date) accrued
interest on, all the Securities or portions thereof which are to be redeemed on
that date.

         SECTION 1106.     SECURITIES PAYABLE ON REDEMPTION DATE.

         Notice of redemption having been given as aforesaid, the Securities so
to be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified in the currency or currencies, currency unit
or units or composite currency or currencies in which the Securities of such
series are payable (except as otherwise specified pursuant to Section 301 for
the Securities of such series) (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 Securities
shall, if the same were interest-bearing, cease to bear interest. Upon surrender
of any such Security for redemption in accordance with said notice, such
Security shall be paid by the Company at the Redemption Price, together with
accrued interest, if any, to the Redemption Date; provided, however, that except
as otherwise provided with respect to Securities convertible or exchangeable
into other securities or property (including securities of other issuers,
provided that such securities are registered under Section 12 of the Exchange
Act and such issuer is then eligible to use Form S-3 (or any successor form) for
a primary offering of its securities) of the Company, installments of interest
on Registered Securities whose Stated Maturity is on or prior to the Redemption
Date shall be payable to the Holders of such securities, or one or more
Predecessor securities, registered as such at the close of business on the
relevant Record Dates according to their terms and the provisions of Section
307.

         If any Security called for redemption shall not be so paid upon
surrender thereof for redemption, the principal, (and premium or Make-Whole
Amount, if any) shall, until paid, bear interest from the Redemption Date at the
rate borne by the Security.

         SECTION 1107.     SECURITIES REDEEMED IN PART.

         Any Security which is to be redeemed only in part (pursuant to the
provisions of this Article or of Article Twelve) shall be surrendered at a Place
of Payment therefor (with, if the Company or the Trustee so requires, due
endorsement by, or a written instrument of transfer in form satisfactory to the
Company and the Trustee duly executed by, the Holder thereof or his attorney
duly authorized in writing) and the Company shall execute and the Trustee shall
authenticate and deliver to the Holder of such Security without service charge a
new Security or Securities of the same series, 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 Security so surrendered.

                                 ARTICLE TWELVE

                                  SINKING FUNDS

         SECTION 1201.     APPLICABILITY OF ARTICLE.

         The provisions of this Article shall be applicable to any sinking fund
for the retirement of Securities of a series except as otherwise specified as
contemplated by Section 301 for Securities of such series.

         The minimum amount of any sinking fund payment provided for by the
terms of Securities of any series is herein referred to as a "mandatory sinking
fund payment," and any payment in excess of such minimum amount provided for by
the terms of such Securities of any series is herein referred to as an "optional
sinking fund payment." If provided for by the terms of any Securities of any
series, the cash amount of any mandatory sinking fund payment may be subject to
reduction as provided in Section 1202. Each sinking fund payment shall be
applied to the redemption of Securities of any series as provided for by the
terms of Securities of such series.

         SECTION 1202.     SATISFACTION OF SINKING FUND PAYMENTS WITH
SECURITIES.

         The Company may, in satisfaction of all or any part of any mandatory
sinking fund payment with respect to the Securities of a series, (1) deliver
Outstanding Securities of such series (other than any previously called for
redemption) and (2) apply as a credit Securities of such series which have been
redeemed either at the election of the Company pursuant to the terms of such
Securities or through the application of permitted optional sinking fund
payments pursuant to the terms of such Securities, as provided for by the terms
of such Securities, or which have otherwise been acquired by the Company;
provided that such Securities so delivered or applied as a credit have not been
previously so credited. Such Securities shall be received and credited for such
purpose by the Trustee at the applicable Redemption Price specified in such
Securities for redemption through operation of the sinking fund and the amount
of such mandatory sinking fund payment shall be reduced accordingly.

         SECTION 1203.     REDEMPTION OF SECURITIES FOR SINKING FUND.

         Not less than 60 days prior to each sinking fund payment date for
Securities of any series, the Company will deliver to the Trustee an Officers'
Certificate specifying the amount of the next ensuing mandatory sinking fund
payment for that series pursuant to the terms of that series, the portion
thereof, if any, which is to be satisfied by payment of cash in the currency or
currencies, currency unit or units or composite currency or currencies in which
the Securities of such series are payable (except as otherwise specified
pursuant to Section 301 for the Securities of such series) and the portion
thereof, if any, which is to be satisfied by delivering and crediting Securities
of that series pursuant to Section 1202, and the optional amount, if any, to be
added in cash to the next ensuing mandatory sinking fund payment, and will also
deliver to the Trustee any Securities to be so delivered and credited. If such
Officers' Certificate shall specify an

                                      -65-

<PAGE>

optional amount to be added in cash to the next ensuing mandatory sinking fund
payment, the Company shall thereupon be obligated to pay the amount therein
specified. Not less than 30 days before each such sinking fund payment date the
Trustee shall select the Securities to be redeemed upon such sinking fund
payment date in the manner specified in Section 1103 and cause notice of the
redemption thereof to be given in the name of and at the expense of the Company
in the manner provided in Section 1104. Such notice having been duly given, the
redemption of such Securities shall be made upon the terms and in the manner
stated in Sections 1106 and 1107.

                                ARTICLE THIRTEEN

                       REPAYMENT AT THE OPTION OF HOLDERS

         SECTION 1301.     APPLICABILITY OF ARTICLE.

         Repayment of Securities of any series before their Stated Maturity at
the option of Holders thereof shall be made in accordance with the terms of such
Securities, if any, and (except as otherwise specified by the terms of such
series established pursuant to Section 301) in accordance with this Article.

         SECTION 1302.     REPAYMENT OF SECURITIES.

         Securities of any series subject to repayment in whole or in part at
the option of the Holders thereof will, unless otherwise provided in the terms
of such Securities, be repaid at a price equal to the principal amount thereon,
together with interest, if any, thereof accrued to the Repayment Date specified
in or pursuant to the terms of such Securities. The Company covenants that on or
before the Repayment Date it will 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 in the currency or
currencies, currency unit or units or composite currency or currencies in which
the Securities of such series are payable (except as otherwise specified
pursuant to Section 301 for the Securities of such series) sufficient to pay the
principal (or, if so provided by the terms of the Securities of any series, a
percentage of the principal) of, and (except if the Repayment Date shall be an
Interest Payment Date) accrued interest on, all the Securities or portions
thereof, as the case may be, to be repaid on such date.

         SECTION 1303.     EXERCISE OF OPTION.

         Securities of any series subject to repayment at the option of the
Holders thereof will contain an "Option to Elect Repayment" form on the reverse
of such Securities. In order for any Security to be repaid at the option of the
Holder, the Trustee must receive at the Place of Payment therefor specified in
the terms of such Security (or at such other place or places of which the
Company shall from time to time notify the Holders of such Securities) not
earlier than 60 days nor later than 30 days prior to the Repayment Date (1) the
Security so providing for such repayment together with the "Option to Elect
Repayment" form on the reverse thereof duly completed by the Holder (or by the
Holder's attorney duly authorized in writing) or (2) a

telegram, telex, facsimile transmission or a letter from a member of a national
securities exchange, or the National Association of Securities Dealers, Inc.
("NASD"), or a commercial bank or trust company in the United States setting
forth the name of the Holder of the Security, the principal amount of the
Security, the principal amount of the Security to be repaid, the CUSIP number,
if any, or a description of the tenor and terms of the Security, a statement
that the option to elect repayment is being exercised thereby and a guarantee
that the Security to be repaid, together with the duly completed form entitled
"Option to Elect Repayment" on the reverse of the Security, will be received by
the Trustee not later than the fifth Business Day after the date of such
telegram, telex, facsimile transmission or letter; provided, however, that such
telegram, telex, facsimile transmission or letter shall only be effective if
such Security and form duly completed are received by the Trustee by such fifth
Business Day. If less than the entire principal amount of such Security is to be
repaid in accordance with the terms of such Security, the principal amount of
such Security to be repaid, in increments of the minimum denomination for
Securities of such series, and the denomination or denominations of the Security
or Securities to be issued to the Holder for the portion of the principal amount
of such Security surrendered that is not to be repaid, must be specified. The
principal amount of any Security providing for repayment at the option of the
Holder thereof may not be repaid in part if, following such repayment, the
unpaid principal amount of such Security would be less than the minimum
authorized denomination of Securities of or within the series of which such
Security to be repaid is a part. Except as otherwise may be provided by the
terms of any Security providing for repayment at the option of the Holder
thereof, exercise of the repayment option by the Holder shall be irrevocable
unless waived by the Company.

         SECTION 1304.     WHEN SECURITIES PRESENTED FOR REPAYMENT BECOME DUE
AND PAYABLE.

         If Securities of any series providing for repayment at the option of
the Holders thereof shall have been surrendered as provided in this Article and
as provided by or pursuant to the terms of such Securities, such Securities or
the portions thereof, as the case may be, to be repaid shall become due and
payable and shall be paid by the Company on the Repayment Date therein
specified, and on and after such Repayment Date (unless the Company shall
default in the payment of such Securities on such Repayment Date) such
Securities shall, if the same were interest bearing, cease to bear interest.
Upon surrender of any such Security for repayment in accordance with such
provisions, the principal amount of such security so to be repaid shall be paid
by the Company, together with accrued interest, if any, to the Repayment Date;
provided, however, that, in the case of Registered Securities, installments of
interest, if any, whose Stated Maturity is on or prior to the Repayment Date
shall be payable (but without interest thereon, unless the Company shall default
in the payment thereof) to the Holders of such Securities, or one or more
Predecessor Securities, registered as such at the close of business on the
relevant Record Dates according to their terms and the provisions of Section
307.

         If the principal amount of any Security surrendered for repayment shall
not be so repaid upon surrender thereof, such principal amount (together with
interest, if any, thereon accrued to such Repayment Date) shall, until paid,
bear interest from the Repayment Date at the rate of interest or Yield to
Maturity (in the case of Original Issue Discount Securities) set forth in such
Security.

         SECTION 1305.     SECURITIES REPAID IN PART.

         Upon surrender of any Registered Security which is to be repaid in part
only, the Company shall execute and the Trustee shall authenticate and deliver
to the Holder of such Security, without service charge and at the expense of the
Company, a new Registered Security or Securities of the same series, of any
authorized denomination specified by the Holder, in an aggregate principal
amount equal to and in exchange for the portion of the principal of such
Security so surrendered which is not to be repaid.

                                ARTICLE FOURTEEN

                       DEFEASANCE AND COVENANT DEFEASANCE

         SECTION 1401.     APPLICABILITY OF ARTICLE; COMPANY'S OPTION TO EFFECT
DEFEASANCE OR COVENANT DEFEASANCE.

         If, pursuant to Section 301, provision is made for either or both of
(a) defeasance of the Securities of or within a series under Section 1402 or (b)
covenant defeasance of the Securities of or within a series under Section 1403
to be applicable to the Securities of any series, then the provisions of such
Section or Sections, as the case may be, together with the other provisions of
this Article (with such modifications thereto as may be specified pursuant to
Section 301 with respect to any Securities), shall be applicable to such
Securities, and the Company may at its option by Board Resolution at any time,
with respect to such Securities, elect to defease such Outstanding Securities
pursuant to Section 1402 (if applicable) or Section 1403 (if applicable) upon
compliance with the conditions set forth below in this Article.

         SECTION 1402.     DEFEASANCE AND DISCHARGE.

         Upon the Company's exercise of the above option applicable to this
Section with respect to any Securities of or within a series, the Company and
each Security Guarantor shall be deemed to have been discharged from its
obligations with respect to such Outstanding Securities on the date the
conditions set forth in Section 1404 are satisfied (hereinafter, "defeasance").
For this purpose, such defeasance means that the Company and each Security
Guarantor shall be deemed to have paid and discharged the entire indebtedness
represented by such Outstanding Securities, which shall thereafter be deemed to
be "Outstanding" only for the purposes of Section 1405 and the other Sections of
this Indenture referred to in clauses (A) and (B) below, and to have satisfied
all of its other obligations under such Securities and this Indenture and any
Security Guarantee insofar as such Securities 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 such Outstanding
Securities to receive, solely from the trust fund described in Section 1404 and
as more fully set forth in such Section, payments in respect of the principal of
(and premium or Make-Whole Amount, if any) and interest, if any, on such
Securities when such payments are due, (B) the Company's obligations with
respect to such Securities under Sections 305, 306, 1002 and 1003 and with
respect to the payment of Additional Amounts, if any, on such

                                      -68-

<PAGE>

Securities as contemplated by Section 1010, (C) the rights, powers, trusts,
duties and immunities of the Trustee hereunder and (D) this Article. Subject to
compliance with this Article Fourteen, the Company may exercise its option under
this Section notwithstanding the prior exercise of its option under Section 1403
with respect to such Securities.

         SECTION 1403.     COVENANT DEFEASANCE.

         Upon the Company's exercise of the above option applicable to this
Section with respect to any Securities of or within a series, the Company and
each Security Guarantor shall be released from their obligations under Sections
1004 to 1008, inclusive, and, if specified pursuant to Section 301, their
obligations under any other covenant, with respect to such Outstanding
Securities, and any relating Security Guarantee, on and after the date the
conditions set forth in Section 1404 are satisfied (hereinafter, "covenant
defeasance"), and such Securities, and any relating Security Guarantee, shall
thereafter be deemed to be not "Outstanding" for the purposes of any direction,
waiver, consent or declaration or Act of Holders (and the consequences of any
thereof) in connection with Sections 1004 to 1008, inclusive, or such other
covenant, but shall continue to be deemed "Outstanding" for all other purposes
hereunder. For this purpose, such covenant defeasance means that, with respect
to such Outstanding Securities, and any relating Security Guarantee, the Company
and each Security Guarantor may omit to comply with and shall have no liability
in respect of any term, condition or limitation set forth in any such Section or
such other covenant, whether directly or indirectly, by reason of any reference
elsewhere herein to any such Section or such other covenant or by reason of
reference in any such Section or such other 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(4) or 501(8) or otherwise, as
the case may be, but, except as specified above, the remainder of this Indenture
and such Securities shall be unaffected thereby.

         SECTION 1404.     CONDITIONS TO DEFEASANCE OR COVENANT DEFEASANCE.

         The following shall be the conditions to application of Section 1402 or
Section 1403 to any Outstanding Securities of or within a series:

         (a)      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
Fourteen 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 Securities, (1) an amount in such
currency, currencies or currency unit in which such Securities are then
specified as payable at Stated Maturity, or (2) Government Obligations
applicable to such Securities (determined on the basis of the currency,
currencies or currency unit in which such Securities are then specified as
payable at Stated Maturity) which through the scheduled payment of principal and
interest in respect thereof in accordance with their terms will provide, not
later than one day before the due date of any payment of principal of (and
premium or Make-Whole Amount, if any) and interest, if any, on such Securities,
money in an amount, or (3) a combination thereof in an amount, sufficient,
without consideration of any reinvestment of such principal and interest, in the
opinion of a nationally recognized firm of independent public accountants
expressed in a written certification

                                      -69-

<PAGE>

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 or Make-Whole Amount, if any) and interest, if
any, on such Outstanding Securities on the Stated Maturity of such principal or
installment of principal or interest and (ii) any mandatory sinking fund
payments or analogous payments applicable to such Outstanding Securities on the
day on which such payments are due and payable in accordance with the terms of
this Indenture and of such Securities; provided, that the Trustee shall have
been irrevocably instructed to apply such money or the proceeds of such
Government Obligations to said payments with respect to such Securities. Before
such a deposit, the Company may give to the Trustee, in accordance with Section
1102 hereof, a notice of its election to redeem all or any portion of such
Outstanding Securities at a future date in accordance with the terms of the
Securities of such series and Article Eleven hereof, which notice shall be
irrevocable. Such irrevocable redemption notice, if given, shall be given effect
in applying the foregoing.

         (b)      Such defeasance or covenant defeasance shall not result in a
breach or violation of, or constitute a default under, this Indenture or any
other material agreement or instrument to which the Company is a party or by
which it is bound (and shall not cause the Trustee to have a conflicting
interest pursuant to Section 310(b) of the TIA with respect to any Security of
the Company).

         (c)      No Event of Default or event which with notice or lapse of
time or both would become an Event of Default with respect to such Securities
shall have occurred and be continuing on the date of such deposit or, insofar as
Sections 501(7) and 501(8) are concerned, at any time during the period ending
on the 91st day after the date of such deposit (it being understood that this
condition shall not be deemed satisfied until the expiration of such period).

         (d)      In the case of an election under Section 1402, the Company
shall have delivered to the Trustee an Opinion of Counsel stating that (i) the
Company has received from, or there has been published by, the Internal Revenue
Service a ruling, or (ii) since the date of execution of this Indenture, there
has been a change in the applicable Federal income tax law, in either case to
the effect that, and based thereon such opinion shall confirm that, the Holders
of such Outstanding Securities 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.

         (e)      In the case of an election under Section 1403, the Company
shall have delivered to the Trustee an Opinion of Counsel to the effect that the
Holders of such Outstanding Securities 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.

         (f)      The Company shall have delivered to the Trustee an Officers'
Certificate and an Opinion of Counsel, each stating that all conditions
precedent to the defeasance under Section 1402 or the covenant defeasance under
Section 1403 (as the case may be) have been complied

                                      -70-

<PAGE>

with and an Opinion of Counsel to the effect that either (i) as a result of a
deposit pursuant to subsection (a) above and the related exercise of the
Company's option under Section 1402 or Section 1403 (as the case may be)
registration is not required under the Investment Company Act of 1940, as
amended, by the Company, with respect to the trust funds representing such
deposit or by the Trustee for such trust funds or (ii) all necessary
registrations under said Act have been effected.

         (g)      After the 91st day following the deposit, the trust funds will
not be subject to the effect of any applicable bankruptcy, insolvency,
reorganization or similar laws affecting creditors' rights generally.

         (h)      Notwithstanding any other provisions of this Section, such
defeasance or covenant defeasance shall be effected in compliance with any
additional or substitute terms, conditions or limitations which may be imposed
on the Company in connection therewith pursuant to Section 301.

         SECTION 1405.     DEPOSITED MONEY AND GOVERNMENT OBLIGATIONS TO BE HELD
IN TRUST; OTHER MISCELLANEOUS PROVISIONS.

         Subject to the provisions of the last paragraph of Section 1003, all
money and Government Obligations (or other property as may be provided pursuant
to Section 301) (including the proceeds thereof) deposited with the Trustee (or
other qualifying trustee, collectively for purposes of this Section 1405, the
"Trustee") pursuant to Section 1404 in respect of any Outstanding Securities of
any series shall be held in trust and applied by the Trustee, in accordance with
the provisions of such Securities and this Indenture, to the payment, either
directly or through any Paying Agent (including the Company acting as its own
Paying Agent) as the Trustee may determine, to the Holders of such Securities of
all sums due and to become due thereon in respect of principal (and premium or
Make-Whole Amount, if any) and interest and Additional Amounts, if any, but such
money need not be segregated from other funds except to the extent required by
law.

         Unless otherwise specified with respect to any Security pursuant to
Section 301, if, after a deposit referred to in Section 1404(a) has been made,
the Holder of a Security in respect of which such deposit was made is entitled
to, and does, elect pursuant to Section 301 or the terms of such Security to
receive payment in a currency or currency unit other than that in which the
deposit pursuant to Section 1404(a) has been made in respect of such Security,
the indebtedness represented by such Security shall be deemed to have been, and
will be, fully discharged and satisfied through the payment of the principal of
(and premium or Make-Whole Amount, if any), and interest, if any, on such
Security as the same becomes due out of the proceeds yielded by converting (from
time to time as specified below in the case of any such election) the amount or
other property deposited in respect of such Security into the currency or
currency unit in which such Security becomes payable as a result of such
election based on the applicable market exchange rate for such currency or
currency unit in effect on the second Business Day prior to each payment date.

                                      -71-

<PAGE>

         The Company shall pay and indemnify the Trustee against any tax, fee or
other charge imposed on or assessed against the Government Obligations deposited
pursuant to Section 1404 or the principal and interest received in respect
thereof other than any such tax, fee or other charge which by law is for the
account of the Holders of such Outstanding Securities.

         Anything in this Article to the contrary notwithstanding, the Trustee
shall deliver or pay to the Company from time to time upon Company Request any
money or Government Obligations (or other property and any proceeds therefrom)
held by it as provided in Section 1404 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 a defeasance or
covenant defeasance, as applicable, in accordance with this Article.

proposed to be taken at the meeting, and the Trustee shall not have made the

                  waiver or other action has been made, given or taken under
                  this Indenture.

         SECTION 1505.     DETERMINATION OF VOTING RIGHTS; CONDUCT AND
ADJOURNMENT OF MEETINGS.

         (a)      Notwithstanding any provisions of this Indenture, the Trustee
may make such reasonable regulations as it may deem advisable for any meeting of
Holders of Securities of a series in regard to proof of the holding of
Securities of such series and of the appointment of proxies and in regard to the
appointment and duties of inspectors of votes, the submission and examination of
proxies, certificates and other evidence of the right to vote, and such other
matters concerning the conduct of the meeting as it shall deem appropriate.
Except as otherwise permitted or required by any such regulations, the holding
of Securities shall be proved in the manner specified in Section 104 and the
appointment of any proxy shall be proved in the manner specified in Section 104.
Such regulations may provide that written instruments appointing proxies,
regular on their face, may be presumed valid and genuine without the proof
specified in Section 104 or other proof.

         (b)      The Trustee shall, by an instrument in writing, appoint a
temporary chairman of the meeting, unless the meeting shall have been called by
the Company or by Holders of Securities as provided in Section 1502(b), in which
case the Company or the Holders of Securities of or within the series calling
the meeting, as the case may be, shall in like manner appoint a temporary
chairman. A permanent chairman and a permanent secretary of the meeting shall be
elected by vote of the Persons entitled to vote a majority in principal amount

proxy shall be entitled to one vote for each $1,000 principal amount of the
Outstanding Securities of such series held or represented by him; provided,
however, that no vote shall be cast or counted at any meeting in respect of any
Security challenged as not Outstanding and ruled by the chairman of the meeting
to be not Outstanding. The chairman of the meeting shall have no right to vote,
except as a Holder of a Security of such series or proxy.

Securities of any series shall be by written ballots on which shall be
subscribed the signatures of the Holders of Securities of such series or of
their representatives by proxy and the principal amounts and serial numbers of
the Outstanding Securities of such series held or represented by them. The
permanent chairman of the meeting shall appoint two inspectors of votes who
shall count all votes cast at the meeting for or against any resolution and who
shall make and file with the secretary of the meeting their verified written
reports in duplicate of all votes cast at the meeting. A record, at least in
duplicate, of the proceedings of each meeting of Holders of Securities of any
series shall be prepared by the secretary of the meeting and there shall be
attached to said record the original reports of the inspectors of votes on any
vote by ballot taken thereat and affidavits by one or more persons having
knowledge of the fact, setting forth a copy of the notice of the meeting and
showing that said notice was given as provided in Section 1502 and, if
applicable, Section 1504. Each copy shall be signed and verified by the
affidavits of the permanent chairman and secretary of the meeting and one such
copy shall be delivered to the Company and another to the Trustee to be
preserved by the Trustee, the latter to have attached thereto the ballots voted
at the meeting. Any record so signed and verified shall be conclusive evidence
of the matters therein stated.

         SECTION 1507.     EVIDENCE OF ACTION TAKEN BY HOLDERS.

         Any request, demand, authorization, direction, notice, consent, waiver
or other action provided by this Indenture to be given or taken by a specified
percentage in principal amount of the Holders of any or all series may be
embodied in and evidenced by one or more instruments of substantially similar
tenor signed by such specified percentage of Holders in person or by agent 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. Proof of execution of any instrument or of a writing appointing
any such agent shall be sufficient for any purpose of this Indenture and
(subject to Article Six) conclusive in favor of the Trustee and the Company, if
made in the manner provided in this Article.

         SECTION 1508.     PROOF OF EXECUTION OF INSTRUMENTS.

         Subject to Article Six, the execution of any instrument by a Holder or
his agent or proxy may be proved in accordance with such reasonable rules and
regulations as may be prescribed by the Trustee or in such manner as shall be
satisfactory to the Trustee.

                                 ARTICLE SIXTEEN
                      CONVERSION OR EXCHANGE OF SECURITIES

         SECTION 1601.     APPLICABILITY OF ARTICLE.

         The provisions of this Article shall be applicable to the Securities of
any series which are convertible or exchangeable for other securities or
property (including securities of other issuers, provided that such securities
are registered under Section 12 of the Exchange Act and such issuer is then
eligible to use Form S-3 (or any successor form) for a primary offering of its
securities) of the Company, except as otherwise specified as contemplated by
Section 301 for the Securities of such series.

         SECTION 1602.     ELECTION TO EXCHANGE; NOTICE TO TRUSTEE AND HOLDERS.

         The election of the Company to exchange any Securities shall be
evidenced by a Board Resolution or in another manner specified as contemplated
by Section 301 for such Securities. On or prior to the seventh Business Day
prior to Maturity of the Securities, the Company shall provide written notice to
the Holders of record of the Securities and to the Trustee and will publish a
notice in an Authorized Newspaper stating whether the Company has made such
election.

         SECTION 1603.     NO FRACTIONAL SHARES.

         No fractional shares or fractional securities shall be delivered upon
exchanges of Securities of any series. If more than one Security shall be
surrendered for exchange at one time by the same Holder, the number of full
shares or units which shall be delivered upon exchange shall be computed on the
basis of the aggregate principal amount of the Securities (or specified portions
thereof to the extent permitted hereby) so surrendered. If, except for the
provisions of this Section 1603, any Holder of a Security or Securities would be
entitled to a fractional share or unit of a security upon the exchange of such
Security or Securities, or specified portions thereof, the Company shall pay to
such Holder an amount in cash equal to the current market value of such
fractional share computed on the basis of the Closing Price of such security on
the date preceding the date on which the conversion or exchange shall be
effected in accordance with Section 1610. The "Closing Price" of any security on
any date of determination means, (i) if such security is listed or admitted to
unlisted trading privileges on a national securities exchange, the last reported
sales price on the composite tape on such exchange, or (ii) if such security is
not at the time so listed or admitted to unlisted trading privileges on a
national securities exchange, the average of the bid and asked prices of such
security in the over-the-counter market, as reported by Nasdaq or the National
Quotation Bureau, Incorporated or similar organization if neither Nasdaq nor the
National Quotation Bureau, Incorporated is no longer reporting such information,
or if not so available, the market price as determined by a nationally
recognized investment banking firm retained for this purpose by the Company.

         SECTION 1604.     ADJUSTMENT OF EXCHANGE RATE.

         The exchange rate of Securities of any series that is exchangeable for
other securities or property (including securities of other issuers, provided
that such securities are registered under Section 12 of the Exchange Act and
such issuer is then eligible to use Form S-3 (or any successor form) for a
primary offering of its securities) shall be adjusted for any stock dividends,
stock splits, reclassification, combinations or similar transactions or any
consolidation, merger or other reorganization event in accordance with the terms
of the supplemental indenture or Board Resolution setting forth the terms of the
Securities of such series.

         Whenever the exchange rate is adjusted, the Company shall compute the
adjusted exchange rate in accordance with terms of the applicable Board
Resolution or supplemental indenture and shall prepare an Officers' Certificate
setting forth the adjusted exchange rate and showing in reasonable detail the
facts upon which such adjustment is based, and such certificate shall forthwith
be filed at each office or agency maintained for the purpose of exchange of
Securities pursuant to Section 1002 and, if different, with the Trustee. The
Company shall forthwith cause a notice setting forth the adjusted exchange rate
to be mailed, first class postage prepaid, to each Holder of Securities of such
series at its address appearing on the Security Register and to any exchange
agent other than the Trustee.

         SECTION 1605.     PAYMENT OF CERTAIN TAXES UPON EXCHANGE.

         The Company will pay any and all taxes that may be payable in respect
of the transfer and delivery of shares of other securities or property
(including securities of other issuers, provided that such securities are
registered under Section 12 of the Exchange Act and such issuer is then eligible
to use Form S-3 (or any successor form) for a primary offering of its
securities) of the Company on exchange of Securities pursuant hereto. The
Company shall not, however, be required to pay any tax which may be payable in
respect of any transfer involved in the delivery of shares of securities in a
name other than that of the Holder of the Security or Securities to be
exchanged, and no such transfer or delivery shall be made unless and until the
person requesting such transfer has paid to the Company the amount of any such
tax, or has established, to the satisfaction of the Company, that such tax has
been paid.

         SECTION 1606.     SHARES FREE AND CLEAR.

         The Company hereby warrants that upon exchange of Securities of any
series, the Holder of a Security shall receive all rights held by the Company in
such security for which such Security is at such time exchangeable under this
Article Sixteen, free and clear of any and all liens, claims, charges and
encumbrances other than any liens, claims, charges and encumbrances which may
have been placed on any such security by the prior owner thereof, prior to the
time such security was acquired by the Company. Except as provided in Section
1604, the Company will pay all taxes and charges with respect to the delivery of
such security delivered in exchange for Securities hereunder.

                                      -77-

<PAGE>

         SECTION 1607.     CANCELLATION OF SECURITY.

         Upon receipt by the Trustee of Securities of any series delivered to it
for exchange under this Article Sixteen, the Trustee shall cancel and dispose of
the same as provided in Section 309.

         SECTION 1608.     DUTIES OF TRUSTEE REGARDING EXCHANGE.

         Neither the Trustee nor any exchange agent shall at any time be under
any duty or responsibility to any Holder of Securities of any series that is
exchangeable into other securities or property (including securities of other
issuers, provided that such securities are registered under Section 12 of the
Exchange Act and such issuer is then eligible to use Form S-3 (or any successor
form) for a primary offering of its securities) of the Company to determine
whether any facts exist which may require any adjustment of the exchange rate,
or with respect to the nature or extent of any such adjustment when made, or
with respect to the method employed, whether herein or in any supplemental
indenture, any resolutions of the Board of Directors or written instrument
executed by one or more officers of the Company provided to be employed in
making the same. Neither the Trustee nor any exchange agent shall be accountable
with respect to the validity or value (or the kind or amount) of any securities
or property (including securities of other issuers, provided that such
securities are registered under Section 12 of the Exchange Act and such issuer
is then eligible to use Form S-3 (or any successor form) for a primary offering
of its securities) of the Company, or of any Securities and neither the Trustee
nor any exchange agent makes any representation with respect thereto. Subject to
the provisions of Section 612, neither the Trustee nor any exchange agent shall
be responsible for any failure of the Company to issue, transfer or deliver any
stock certificates or other securities or property (including securities of
other issuers, provided that such securities are registered under Section 12 of
the Exchange Act and such issuer is then eligible to use Form S-3 (or any
successor form) for a primary offering of its securities) upon the surrender of
any Security for the purpose of exchange or to comply with any of the covenants
of the Company contained in this Article Sixteen or in the applicable
supplemental indenture, resolutions of the Board of Directors or written
instrument executed by one or more duly authorized officers of the Company.

         SECTION 1609.     REPAYMENT OF CERTAIN FUNDS UPON EXCHANGE.

         Any funds which at any time shall have been deposited by the Company or
on its behalf with the Trustee or any other paying agent for the purpose of
paying the principal of, and premium, if any, and interest, if any, on any of
the Securities (including funds deposited for the sinking fund referred to in
Article Twelve hereof) and which shall not be required for such purposes because
of the exchange of such Securities as provided in this Article Sixteen shall
after such exchange be repaid to the Company by the Trustee upon the Company's
written request.

         SECTION 1610.     EXERCISE OF CONVERSION OR EXCHANGE PRIVILEGE.

         In order to exercise a conversion or exchange privilege, the Holder of
a Security of a series with such a privilege shall surrender such Security to
the Company at the office or agency maintained for that purpose pursuant to
Section 1002, accompanied by written notice to the

                                      -78-

<PAGE>

Company that the Holder elects to convert or exchange such Security or a
specified portion thereof. Such notice shall also state, if different from the
name or names (with address) in which the Securities are registered, the name or
names in which the Securities or property (including securities of other
issuers, provided that such securities are registered under Section 12 of the
Exchange Act and such issuer is then eligible to use Form S-3 (or any successor
form) for a primary offering of its securities) of the Company which shall be
issuable on such conversion or exchange shall be issued. Securities surrendered
for conversion or exchange shall (if so required by the Company or the Trustee)
be duly endorsed by or accompanied by instruments of transfer in forms
satisfactory to the Company and the Trustee duly executed by the registered
Holder or its attorney duly authorized in writing; and Securities so surrendered
for conversion or exchange during the period from the close of business on any
Regular Record Date to the opening of business on the next succeeding Interest
Payment Date (excluding Securities or portions thereof called for redemption
during such period) shall also be accompanied by payment in funds acceptable to
the Company of an amount equal to the interest payable on such Interest Payment
Date on the principal amount of such Security then being converted, and such
interest shall be payable to such registered Holder notwithstanding the
conversion or exchange of such Security, subject to the provisions of Section
307 relating to the payment of Defaulted Interest by the Company. As promptly as
practicable after the receipt of such notice and of any payment required
pursuant to a Board Resolution and, subject to Section 303, set forth, or
determined in the manner provided, in an Officers' Certificate, or established
in one or more indentures supplemental hereto setting forth the terms of such
series of Security, and the surrender of such Security in accordance with such
reasonable regulations as the Company may prescribe, the Company shall issue and
shall deliver, at the office or agency at which such Security is surrendered, to
such Holder or on its written order, securities or property (including
securities of other issuers, provided that such securities are registered under
Section 12 of the Exchange Act and such issuer is then eligible to use Form S-3
(or any successor form) for a primary offering of its securities) of the Company
issuable or deliverable upon the conversion or exchange of such Security (or
specified portion thereof), in accordance with the provisions of such Board
Resolution, Officers' Certificate or supplemental indenture, and cash as
provided therein in respect of any fractional share otherwise issuable upon such
conversion or exchange. Such conversion or exchange shall be deemed to have been
effected immediately prior to the close of business on the date on which such
notice and such payment, if required, shall have been received in proper order
for conversion or exchange by the Company and such Security shall have been
surrendered as aforesaid (unless such Holder shall have so surrendered such
Security and shall have instructed the Company to effect the conversion or
exchange on a particular date following such surrender and such Holder shall be
entitled to convert or exchange such Security on such date, in which case such
conversion or exchange shall be deemed to be effected immediately prior to the
close of business on such date) and at such time the rights of the Holder of
such Security as such Security Holder shall cease and the person or persons in
whose name or names any securities or property (including securities of other
issuers, provided that such securities are registered under Section 12 of the
Exchange Act and such issuer is then eligible to use Form S-3 (or any successor
form) for a primary offering of its securities) of the Company shall be issuable
or deliverable upon such conversion or exchange shall be deemed to have become
the Holder or Holders of record of the shares represented thereby. Except as set
forth above and subject to the final paragraph of Section 307, no payment or
adjustment shall be made upon any conversion or exchange on account of any
interest accrued on the Securities

                                      -79-

<PAGE>

surrendered for conversion or exchange or on account of any interest or
dividends on the Securities or property (including securities of other issuers,
provided that such securities are registered under Section 12 of the Exchange
Act and such issuer is then eligible to use Form S-3 (or any successor form) for
a primary offering of its securities) of the Company issued or delivered upon
such conversion or exchange.

         In the case of any Security which is converted or exchanged in part
only, upon such conversion or exchange the Company shall execute and the Trustee
shall authenticate and deliver to or on the order of the Holder thereof, at the
expense of the Company, a new Security or Securities of the same series, of
authorized denominations, in aggregate principal amount equal to the unconverted
or unexchanged portion of such Security.

         SECTION 1611.     EFFECT OF CONSOLIDATION OR MERGER ON CONVERSION
PRIVILEGE.

         In case of any consolidation of the Company with, or merger of the
Company into or with any other Person, or in case of any sale of all or
substantially all of the assets of the Company, the Company or the Person formed
by such consolidation or the Person into which the Company shall have been
merged or the Person which shall have acquired such assets, as the case may be,
shall execute and deliver to the Trustee a supplemental indenture providing that
the Holder of each Security then outstanding of any series that is convertible
into securities of the Company shall have the right, which right shall be the
exclusive conversion right thereafter available to said Holder (until the
expiration of the conversion right of such Security), to convert such Security
into the kind and amount of shares of stock or other securities or property
(including cash) receivable upon such consolidation, merger or sale by a holder
of the number of shares or units of securities of the Company into which such
Security might have been converted immediately prior to such consolidation,
merger or sale, subject to compliance with the other provisions of this
Indenture, such Security and such supplemental indenture. Such supplemental
indenture shall provide for adjustments which shall be as nearly equivalent as
may be practicable to the adjustments provided for in such Security. The above
provisions of this Section shall similarly apply to successive consolidations,
mergers or sales. It is expressly agreed and understood that anything in this
Indenture to the contrary notwithstanding, if, pursuant to such merger,
consolidation or sale, holders of outstanding shares of Common Stock of the
Company or other securities, into which the Security is convertible do not
receive shares of common stock or corresponding other securities of the
surviving corporation, but receive other securities, cash or other property or
any combination thereof, Holders of Securities shall not have the right to
thereafter convert their Securities into common stock or other securities having
substantially identical terms as the Company securities, into which the Security
was originally convertible, of the surviving corporation or the corporation
which shall have acquired such assets, but rather, shall have the right upon
such conversion to receive the other securities, cash or other property
receivable by a holder of the number of shares of Common Stock or such or other
securities of the Company into which the Securities held by such holder might
have been converted immediately prior to such consolidation, merger or sale, all
as more fully provided in the first sentence of this Section 1611. Anything in
this Section 1611 to the contrary notwithstanding, the provisions of this
Section 1611 shall not apply to a merger or consolidation of another corporation
with or into the Company pursuant to which both of the following conditions are
applicable: (i) the Company is the surviving corporation and (ii) the
outstanding shares of

                                      -80-

<PAGE>

Company Common Stock or other securities of the Company into which the Security
was originally convertible are not changed or converted into any other
securities or property (including cash) or reclassified pursuant to the terms of
such merger or consolidation.

         As evidence of the kind and amount of shares of stock or other
securities or property (including cash) into which Securities may properly be
convertible after any such consolidation, merger or sale, or as to the
appropriate adjustments of the conversion prices applicable with respect
thereto, the Trustee shall be furnished with and may accept the certificate or
opinion of an independent certified public accountant with respect thereto; and,
in the absence of bad faith on the part of the Trustee, the Trustee may
conclusively rely thereon, and shall not be responsible or accountable to any
Holder of Securities for any provision in conformity therewith or approved by
such independent certified accountant which may be contained in said
supplemental indenture.

                                ARTICLE SEVENTEEN
                             GUARANTEE OF SECURITIES

         SECTION 1701.     SECURITY GUARANTEES.

         (a)      Each Security Guarantor hereby unconditionally and irrevocably
guarantees to each Holder and to the Trustee and its successors and assigns (a)
the full and punctual payment of principal of, premium, if any, and interest on
the Securities when due, whether at maturity, by acceleration, by redemption or
otherwise, and all other monetary obligations of the Company under this
Indenture and the Securities and (b) the full and punctual performance within
applicable grace periods of all other obligations of the Company under this
Indenture and the Securities to which this Article Seventeen is made applicable
(all the foregoing being hereinafter collectively called the "Guarantee
Obligations"). Each Security Guarantor further agrees that the Guarantee
Obligations may be extended or renewed, in whole or in part, without notice or
further assent from such Security Guarantor and that such Security Guarantor
will remain bound under this Article Seventeen notwithstanding any extension or
renewal of any Guarantee Obligation.

         (b)     Each Security Guarantor waives presentation to, demand of,
payment from and protest to the Company of any of the Guarantee Obligations and
also waives notice of protest for nonpayment. Each Security Guarantor waives
notice of any default under the Securities or the Guarantee Obligations. The
obligations of each Security Guarantor hereunder shall not be affected by (a)
the failure of any Holder or the Trustee to assert any claim or demand or to
enforce any right or remedy against the Company or any other Person under this
Indenture, the Securities or any other agreement or otherwise; (b) any extension
or renewal of any thereof, (c) any rescission, waiver, amendment or modification
of any of the terms or provisions of this Indenture, the Securities or any other
agreement; (d) the release of any security held by any Holder or the Trustee for
the Guarantee Obligations or any of them; (e) the failure of any Holder or
Trustee to exercise any right or remedy against any other guarantor of the
Guarantee Obligations; or (f) any change in the ownership of any Security
Guarantor.

         (c)      Each Security Guarantor further agrees that its Security
Guarantee herein constitutes a guarantee of payment, performance and compliance
when due (and not a guarantee of

                                      -81-

<PAGE>

collection) and waives any right to require that any resort be had by any Holder
or the Trustee to any security held for payment of the Guarantee Obligations.

         (d)      Except as otherwise set forth herein, the Guarantee
Obligations of each Security Guarantor hereunder shall not be subject to any
reduction, limitation, impairment or termination for any reason, including any
claim of waiver, release, surrender, alteration or compromise, and shall not be
subject to any defense of setoff, counterclaim, recoupment or termination
whatsoever or by reason of the invalidity, illegality or unenforceability of the
Guarantee Obligations or otherwise. Without limiting the generality of the
foregoing, the Guarantee Obligations of each Security Guarantor herein shall not
be discharged or impaired or otherwise affected by the failure of any Holder or
the Trustee to assert any claim or demand or to enforce any remedy under this
Indenture, the Securities or any other agreement, by any waiver or modification
of any thereof, by any default, failure or delay, willful or otherwise, in the
performance of the Guarantee Obligations, or by any other act or thing or
omission or delay to do any other act or thing which may or might in any manner
or to any extent vary the risk of each Security Guarantor or would otherwise
operate as a discharge of such Security Guarantor as a matter of law or equity.

         (f)      Each Security Guarantor further agrees that its Security
Guarantee herein shall continue to be effective or be reinstated, as the case
may be, if at any time payment, or any part thereof, of principal, premium, if
any, or interest on any Guarantee Obligation is rescinded or must otherwise be
restored by any Holder or the Trustee upon the bankruptcy or reorganization of
the Company or otherwise.

         (g)      In furtherance of the foregoing and not in limitation of any
other right which any Holder or the Trustee has at law or in equity against any
Security Guarantor by virtue hereof, upon the failure of the Company to pay the
principal of, premium, if any or interest on any Guarantee Obligation when and
as the same shall become due, whether at maturity, by acceleration, by
redemption or otherwise, or to perform or comply with any other Guarantee
Obligation, each Security Guarantor hereby promises to and will, upon receipt of
written demand by the Trustee, forthwith pay, or cause to be paid, in cash or
cash equivalents, to the Trustee an amount equal to the sum of (i) the unpaid
amount of such Guarantee Obligations, (ii) accrued and unpaid interest on such
Guarantee Obligations (but only to the extent not prohibited by law) and (iii)
all other monetary Guarantee Obligations of the Company to the Holders and the
Trustee.

         (h)      Each Security Guarantor agrees that it shall not be entitled
to any right of subrogation in respect of any Guarantee Obligations guaranteed
hereby until payment in full in cash or cash equivalents of all Guarantee
Obligations. Each Security Guarantor further agrees that, as between it, on the
one hand, and the Holders and the Trustee, on the other hand, (x) the maturity
of the Guarantee Obligations guaranteed hereby may be accelerated as provided
herein for the purposes of such Security Guarantor's Security Guarantee herein,
notwithstanding any stay, injunction or other prohibition preventing such
acceleration in respect of the Guarantee Obligations guaranteed hereby, and (y)
in the event of any declaration of acceleration of such Guarantee Obligations as
provided herein, such Guarantee Obligations (whether or not due and

                                      -82-

<PAGE>

payable) shall forthwith become due and payable by such Security Guarantor for
the purposes of this Section 1701.

         (i)      Each Security Guarantor also agrees to pay any and all costs
and expenses (including reasonable attorneys' fees) incurred by the Trustee or
any Holder in enforcing any rights under this Section 1701.

         SECTION 1702.     SUCCESSORS AND ASSIGNS.

         This Article Seventeen shall be binding upon each Security Guarantor
and its successors and assigns and shall inure to the benefit of the successors
and assigns of the Trustee and the Holders and, in the event of any transfer or
assignment of rights by any Holder or the Trustee, the rights and privileges
conferred upon that party in this Indenture and in the Securities shall
automatically extend to and be vested in such transferee or assignee, all
subject to the terms and conditions of this Indenture

         SECTION 1703.     NO WAIVER.

         Neither a failure nor a delay on the part of either the Trustee or the
Holders in exercising any right, power or privilege under this Article Seventeen
shall operate as a waiver thereof, nor shall a single or partial exercise
thereof preclude any other or further exercise of any right, power or privilege.
The rights, remedies and benefits of the Trustee and the Holders herein
expressly specified are cumulative and not exclusive of any other rights,
remedies or benefits which either may have under this Article Seventeen at law,
in equity, by statute or otherwise.

         SECTION 1704.     MODIFICATION.

         No modification, amendment or waiver of any provision of this Article
Seventeen, nor the consent to any departure by any Security Guarantor therefrom,
shall in any event be effective unless the same shall be in writing and signed
by the Trustee, and then such waiver or consent shall be effective only in the
specific instance and for the purpose for which given. No notice to or demand on
any Security Guarantor in any case shall entitle such Security Guarantor to any
other or further notice or demand in the same, similar or other circumstances.

         SECTION 1705.     LIMITATION OF SECURITY GUARANTOR'S LIABILITY.

         Each Security Guarantor, and by its acceptance hereof each Holder,
hereby confirms that it is the intention of all such parties that the Security
Guarantee of such Security Guarantor not constitute a fraudulent transfer or
conveyance for purposes of the Bankruptcy Law, federal and state fraudulent
conveyance laws or any similar federal, state or foreign law. To effectuate the
foregoing intention, the Holders and each Security Guarantor hereby irrevocably
agrees that the obligations of each Security Guarantor under this Article
Seventeen shall be limited to the maximum amount as will, after giving effect to
all other contingent and fixed liabilities of such Security Guarantor and after
giving effect to any collections from or payments made by or on behalf of any
other Security Guarantor in respect of the Guarantee Obligations of such other
Security Guarantor under this Article Seventeen, result in the obligations of
such Security Guarantor under its Security

                                      -83-

<PAGE>

Guarantee not constituting a fraudulent transfer or conveyance under applicable
federal, state or foreign law.

         SECTION 1706.     ADDITIONAL SECURITY GUARANTORS.

         Any Person that was not a Security Guarantor on the date of this
Indenture may become a Security Guarantor by executing and delivering to the
Trustee (a) a supplemental indenture in form and substance reasonably
satisfactory to the Trustee, which subjects such person to the provisions
(including the representations and warranties) of this Indenture as a Security
Guarantor, and (b) an Opinion of Counsel to the effect that such supplemental
indenture has been duly authorized and executed by such Person and constitutes
the legal, valid and binding obligation of such Person (subject to such
customary assumptions and exceptions as may be acceptable to the Trustee in its
reasonable discretion).

         SECTION 1707.     RELEASE OF A SECURITY GUARANTOR.

         Upon the sale, exchange, transfer or other disposition (by merger or
otherwise), other than a lease, of a Subsidiary of the Company that is a
Security Guarantor of all of the capital stock of such Subsidiary or all, or
substantially all, the assets of such Subsidiary, to any person that is not an
Affiliate of the Company, and which sale or other disposition is otherwise in
compliance with the terms of this Indenture, such Security Guarantor shall be
deemed automatically and unconditionally released and discharged from all
obligations under this Article Seventeen without any further action required on
the part of the Trustee or any Holder. The Trustee shall deliver an appropriate
instrument evidencing such release upon receipt of a request of the Company
accompanied by an Officers' Certificate certifying as to the compliance with
this Section. Any Security Guarantor not so released will remain liable for the
full amount of principal of, premium, if any, and interest on the Securities as
provided in this Article Seventeen.

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

                                      -84-

<PAGE>

         IN WITNESS WHEREOF, the parties hereto have caused this Indenture to be
duly executed by their respective officers hereunto duly authorized, all as of
the day and year first above written.

                  1.       Indenture. This Security is one of a duly authorized
issue of Securities of the Company designated as its [___]% Securities due
[___]. The Securities are limited (except as otherwise provided in the Indenture
referred to below) in aggregate principal amount to $[_____], which may be
issued under an indenture (herein called the "Indenture") dated as of
[_____________], by and among the Company, each of the Security Guarantors named
in the Indenture (the "Security Guarantors") and WACHOVIA BANK, NATIONAL
ASSOCIATION, as trustee (herein called the "Trustee," which term includes any
successor Trustee under the Indenture), to which Indenture and all indentures
supplemental thereto reference is hereby made for a statement of the respective
rights, limitations of rights, duties, obligations and immunities thereunder of
the Company, the Trustee, the Security Guarantors and the Holders of the
Securities, and of the terms upon which the Securities are, and are to be,
authenticated and delivered.

                  All capitalized terms used in this Security which are defined
in the Indenture and not otherwise defined herein shall have the meanings
assigned to them in the Indenture.

                  The terms of the Securities include those stated in the
Indenture and those made part of the Indenture by reference to the Trust
Indenture Act of 1939 (15 U.S.C. Sections 77aaa-77bbbb) (the "TIA"), as in
effect on the date of the Indenture. Notwithstanding anything to the contrary
herein, the Securities are subject to all such terms, and Holders of Securities
are referred to the Indenture and the TIA for a statement of such terms.

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

                  [2.      Security Guarantees. This Security is initially
entitled to the benefits of the certain Security Guarantees of the Security
Guarantors and may thereafter be entitled to certain other Security Guarantees
made for the benefit of the Holders. Reference is hereby made to
Article Seventeen of the Indenture and to the Security Guarantees endorsed on
this Security for a statement of the respective rights, limitations of rights,
duties and obligations thereunder of the Security Guarantors, the Trustee and
the Holders.]

                  3.       Redemption. The Securities will be redeemable, in
whole or in part, at the option of the Company, at any time or from time to
time, upon not less than 30 and not more than 60 days' notice mailed to each
Holder of Securities to be redeemed as shown in the security register for the
Securities, on any date prior to their maturity date at a price equal to [_____]
(subject to the right of persons in whose name the Securities are registered on
the

                                      B-4

<PAGE>

relevant record date to receive interest due on an Interest Payment Date that is
on or prior to the Redemption Date).

                  4.       Notice of Redemption. Notice of redemption will be
mailed by first-class mail at least 30 days but not more than 60 days before the
Redemption Date to each Holder of Securities to be redeemed at its registered
address. In the event that less than all of the Securities are to be redeemed at
any time pursuant to an optional redemption, selection of such Securities for
redemption will be made by the Trustee in compliance with the requirements of
the principal national securities exchange, if any, on which the Securities are
listed or, if the Securities are not then listed on a national securities
exchange, on a pro rata basis, by lot or by such method as the Trustee shall
deem fair and appropriate; provided, however, that no Securities of a principal
amount of each class of $1,000 or less shall be redeemed in part; provided,
further, however, that if a partial redemption is made pursuant to the
provisions described in paragraph 3, selection of the Securities or portions
thereof for redemption shall be made by the Trustee only on a pro rata basis or
on as nearly a pro rata basis as is practicable (subject to the procedures of
The Depository Trust Company), unless such method is otherwise prohibited.

                  If any Security is to be redeemed in part only, the notice of
redemption that relates to such Security shall state the portion of the
principal amount thereof to be redeemed. A new Security in a principal amount
equal to the unredeemed portion thereof will be issued in the name of the Holder
thereof upon surrender of the original Security. On and after the Redemption
Date, interest will cease to accrue on Securities or portions thereof called for
redemption as long as the Company has deposited with the Paying Agent for the
Securities funds in satisfaction of the Redemption Price pursuant to the
Indenture.

                  5.       Defaults and Remedies. If an Event of Default occurs
and is continuing, the principal of all of the Outstanding Securities, plus all
accrued and unpaid interest, if any, to and including the date the Securities
are paid, may be declared due and payable in the manner and with the effect
provided in the Indenture.

                  6        Defeasance. The Indenture contains provisions (which
provisions apply to this Security) for defeasance at any time of (a) the entire
indebtedness of the Company and the Security Guarantors on this Security and (b)
certain restrictive covenants and related Defaults and Events of Default, in
each case upon compliance by the Company with certain conditions set forth
therein.

                  7.       Amendments and Waivers. The Indenture permits, with
certain exceptions as provided therein, the amendment thereof and the
modification of the rights and obligations of the Company and the rights of the
Holders under the Indenture at any time by the Company and the Trustee with the
consent of the Holders of not less than a majority in aggregate principal amount
of the Securities at the time Outstanding. The Indenture also contains
provisions permitting the Holders of specified percentages in aggregate
principal

                                      B-5

<PAGE>

amount of the Securities at the time Outstanding, on behalf of the Holders of
all the Securities, to waive compliance by the Company with certain provisions
of the Indenture and certain past defaults under the Indenture and this Security
and their consequences. Any such consent or waiver by or on behalf of the Holder
of this Security shall be conclusive and binding upon such Holder and upon all
future Holders of this Security and of any Security issued upon the registration
of transfer hereof or in exchange herefor or in lieu hereof whether or not
notation of such consent or waiver is made upon this Security.

                  8.       Denominations, Transfer and Exchange. The Securities
are issuable only in registered form without coupons in denominations of $1,000
and any integral multiple thereof. As provided in the Indenture and subject to
certain limitations therein set forth, the Securities are exchangeable for a
like aggregate principal amount of Securities of a different authorized
denomination, as requested by the Holder surrendering the same.

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

                  No service charge shall be made for any registration of
transfer or exchange or redemption of Securities, but the Company may require
payment of a sum sufficient to cover any tax or other governmental charge
payable in connection therewith.

                  9.       Persons Deemed Owners. Prior to and at the time of
due presentment of this Security for registration of transfer, the Company, the
Trustee and any agent of the Company or the Trustee may treat the person in
whose name this Security is registered as the owner hereof for all purposes,
whether or not this Security shall be overdue, and neither the Company, the
Trustee nor any agent shall be affected by notice to the contrary.

                  10.      GOVERNING LAW. THE INDENTURE, THIS SECURITY AND EACH
SECURITY GUARANTEE SET FORTH BELOW SHALL BE GOVERNED BY, AND CONSTRUED IN
ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK WITHOUT GIVING EFFECT TO
PRINCIPLES OF CONFLICTS OF LAW.

                  The Company will furnish to any Holder of a Security upon
written request and without charge a copy of the Indenture. Requests may be made
to: Accredo Health, Incorporated, 1640 Century City Parkway, Suite 101, Memphis,

         [Insert title or sufficient description of Securities to be delivered]

         This is to certify that, as of the date hereof, and except as set forth
below, the above-captioned Securities held by you for our account (i) are owned
by person(s) that are not citizens or residents of the United States, domestic
partnerships, domestic corporations or any estate or trust the income of which
is subject to United States federal income taxation regardless of its source
("United States person(s)"), (ii) are owned by United States person(s) that are
(a) foreign branches of United States financial institutions (financial
institutions, as defined in United States Treasury Regulations Section 1.
165-12(c)(1)(v) are herein referred to as "financial institutions") purchasing
for their own account or for resale, or (b) United States person(s) who acquired
the Securities through foreign branches of United States financial institutions
and who hold the Securities through such United States financial institutions on
the date hereof (and in either case (a) or (b), each such United States
financial institution hereby agrees, on its own behalf or through its agent,
that you may advise__________________ or its agent that such financial
institution will provide a certificate within a reasonable time stating that it
agrees to comply with the requirements of Section 165(j)(3)(A), (B) or (C) of
the United States Internal Revenue Code of 1986, as amended, and the regulations
thereunder), or (iii) are owned by a financial institution for purposes of
resale during the restricted period (as defined in United States Treasury
Regulations Section 1. 1635(c)(2)(i)(D)(7)), and, such financial institution
described in clause (iii) above (whether or not also described in clause (i) or
(ii)), certifies that it has not acquired the Securities for purposes of resale
directly or indirectly to a United States person or to a person within the
United States or its possessions.

         As used herein, "United States" means the United States of America
(including the States and the District of Columbia); and its "possessions"
include Puerto Rico, the U. S. Virgin Islands, Guam, American Samoa, Wake Island
and the Northern Mariana Islands.

         We undertake to advise you promptly by tested telex on or prior to the
date on which you intend to submit your certification relating to the
above-captioned Securities held by you for our account in accordance with your
Operating Procedures if any applicable statement herein is not correct on such
date, and in the absence of any such notification it may be assumed that this
certification applies as of such date. This certificate excepts and does not
relate to [U.S. $] of such interest in the above-captioned Securities in respect
of which we are not able to certify and as to which we understand an exchange
for an interest in a permanent global Security or an exchange for and delivery
of definitive Securities (or, if relevant, collection of any interest) cannot be
made until we do so certify.

<PAGE>

         We understand that this certificate may be required in connection with
certain tax legislation in the United States. If administrative or legal
proceedings are commenced or threatened in connection with which this
