and

      (w) any other terms of the series.

      All Securities of any one series shall be substantially identical except

such resolution of the Board or in any such indenture supplemental hereto. All
Securities of any one series need not be issued at the same time and may be
issued from time to time, consistent with the terms of this Indenture, if so
provided by or pursuant to such Board Resolution or in any such indenture
supplemental hereto.

      Section 2.04. Authentication and Delivery of Securities. At any time and
from time to time after the execution and delivery of this Indenture, the
Issuer may deliver Securities of any series executed by the Issuer to the
Trustee for authentication, and the Trustee shall thereupon authenticate and
deliver such Securities to or upon the written order of the Issuer, signed by
any two officers of the Issuer authorized by the Board to execute any such
order, without any further action by the Issuer. 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 5.01) shall be fully protected in relying upon:

      (a) a certified copy of any resolution or resolutions of the Board
authorizing the action taken pursuant to the resolution or resolutions delivered
under clause 2.04(b) below;

      (b) a copy of any resolution or resolutions of the Board relating to such
series, in each case certified by the Secretary or an Assistant Secretary of the
Issuer;

                                       9
<PAGE>

      (c) an executed supplemental indenture, if any;

      (d) an Officers' Certificate setting forth the form and terms of the
Securities as required pursuant to Section 2.01 and 2.03, respectively and
prepared in accordance with Section 10.05;

      (e) an Opinion of Counsel, prepared in accordance with Section 10.05, to
the effect that

            (i) that the form or forms and terms of such Securities have been
      established by or pursuant to a resolution of the Board or by a
      supplemental indenture as permitted by Section 2.01 and 2.03 in conformity
      with the provisions of this Indenture;

            (ii) that such Securities, when authenticated and delivered by the
      Trustee and issued by the Issuer in the manner and subject to any
      conditions specified in such Opinion of Counsel, will constitute valid and
      binding obligations of the Issuer;

            (iii) that all laws and requirements in respect of the execution and
      delivery by the Issuer of the Securities have been complied with; and

            (iv) covering such other matters as the Trustee may reasonably
      request.

      The Trustee shall have the right to decline to authenticate and deliver
any Securities under this Section if the Trustee, being advised by counsel,
determines that such action may not lawfully be taken by the Issuer or if the
Trustee in good faith by its board of directors or board of trustees, executive
committee, or a trust committee of directors or trustees or Responsible Officers
shall determine that such action would expose the Trustee to personal liability
to existing Holders.

      Section 2.05. Execution of Securities. The Securities shall be signed on
behalf of the Issuer by any two officers of the Issuer authorized by the Board
to execute such Securities, which Securities may, but need not, be attested.
Such signatures may be the manual or facsimile signatures of the present or any
future such officers. Typographical and other minor errors or defects in any
such reproduction of the seal or any such signature shall not affect the
validity or enforceability of any Security that has been duly authenticated and
delivered by the Trustee.

      In case any officer of the Issuer who shall have signed any of the
Securities shall cease to be such officer before the Security so signed shall be
authenticated and delivered by the Trustee or disposed of by the Issuer, such
Security nevertheless may be authenticated and delivered or disposed of as
though

                                       10
<PAGE>

the person who signed such Security had not ceased to be such officer of the
Issuer; and any Security may be signed on behalf of the Issuer by such persons
as, at the actual date of the execution of such Security, shall be the proper
officers of the Issuer, although at the date of the execution and delivery of
this Indenture any such person was not such an officer.

      Section 2.06. Certificate of Authorization. Only such Securities as shall
bear thereon a certificate of authentication substantially in the form
hereinbefore recited, executed by the Trustee by the manual signature of one of
its authorized officers, shall be entitled to the benefits of this Indenture or
be valid or obligatory for any purpose. Such certificate by the Trustee upon any
Security executed by the Issuer shall be conclusive evidence that the Security
so authenticated has been duly authenticated and delivered hereunder and that
the holder is entitled to the benefits of this Indenture.

      Section 2.07. Denomination and Date of Securities; Payments of Interest.
The Securities shall be issuable as registered securities without coupons and in
denominations as shall be specified as contemplated by Section 2.03. In the
absence of any such specification with respect to the Securities of any series,
the Securities of such series shall be issuable in denominations of $1,000 and
any multiple thereof. The Securities shall be numbered, lettered, or otherwise
distinguished in such manner or in accordance with such plan as the officers of
the Issuer executing the same may determine with the approval of the Trustee as
evidenced by the execution and authentication thereof.

      Each Security shall be dated the date of its authentication, shall bear
interest, if any, from the date and shall be payable on the dates, in each case,
which shall be specified as contemplated by Section 2.03.

      The person in whose name any Security of any series is registered at the
close of business on any record date applicable to a particular series with
respect to any interest payment date for such series shall be entitled to
receive the interest, if any, payable on such interest payment date
notwithstanding any transfer or exchange of such Security subsequent to the
record date and prior to such interest payment date, except if and to the extent
the Issuer shall default in the payment of the interest due on such interest
payment date for such series, in which case such defaulted interest shall be
paid to the persons in whose names Outstanding Securities for such series are
registered at the close of business on a subsequent record date (which shall be
not less than five Business Days prior to the date of payment of such defaulted
interest) established by notice given by mail by or on behalf of the Issuer to
the holders of Securities not less than 15 days preceding such subsequent record
date. The term "record date" as used with respect to any interest payment date
(except a date for payment of defaulted interest) shall mean the date specified
as such in the terms of the Securities of any particular series, or, if no such
date is so specified, if such interest payment date is the first day of a

                                       11
<PAGE>

calendar month, the fifteenth day of the next preceding calendar month or, if
such interest payment date is the fifteenth day of a calendar month, the first
day of such calendar month, whether or not such record date is a Business Day.

      Section 2.08. Regulation, Transfer and Exchange. The Issuer will keep or
cause to be kept at each office or agency to be maintained for the purpose as
provided in Section 3.02 a register or registers in which, subject to such
reasonable regulations as it may prescribe, it will register, and will register
the transfer of, Securities as in this Article provided. Such register shall be
in written form in the English language or in any other form capable of being
converted into such form within a reasonable time. At all reasonable times such
register or registers shall be open for inspection by the Trustee.

      Upon due presentation for registration of transfer of any Security of any
series at any such office or agency to be maintained for the purpose as provided
in Section 3.02, the Issuer shall execute and the Trustee shall authenticate and
deliver in the name of the transferee or transferees a new Security or
Securities of the same series in authorized denominations for a like aggregate
principal amount.

      Any Security or Securities of any series may be exchanged for a Security
or Securities of the same series in other authorized denominations, in an equal
aggregate principal amount. Securities of any series to be exchanged shall be
surrendered at any office or agency to be maintained by the Issuer for the
purpose as provided in Section 3.02, and the Issuer shall execute and the
Trustee shall authenticate and deliver in exchange therefor the Security or
Securities of the same series which the Securityholder making the exchange shall
be entitled to receive, bearing numbers not contemporaneously outstanding.

      All Securities presented for registration of transfer, exchange,
redemption or payment shall (if so required by the Issuer or the Trustee) be
duly endorsed by, or be accompanied by a written instrument or instruments of
transfer in form satisfactory to the Issuer and the Trustee duly executed by,
the holder or his attorney duly authorized in writing.

      The Issuer may require payment of a sum sufficient to cover any tax or
other governmental charge that may be imposed in connection with any exchange or
registration of transfer of Securities. No service charge shall be made for any
such transaction.

      The Issuer shall not be required to exchange or register a transfer of (a)
any Securities of any series for a period of 15 days next preceding the first
mailing of notice of redemption of Securities of such series to be redeemed, or
(b) any Securities selected, called or being called for redemption except, in
the case of any Security where notice has been given that such Security is to be
redeemed in part, the portion thereof not so to be redeemed.

                                       12
<PAGE>

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

      Section 2.09. Mutilated, Defaced, Destroyed, Lost and Stolen Securities.
In case any temporary or definitive Security shall become mutilated, defaced or
be destroyed, lost or stolen, the Issuer in its discretion may execute, and upon
the written request of any officer of the Issuer, the Trustee shall authenticate
and deliver, a new Security of the same series, bearing a number not
contemporaneously outstanding, in exchange and substitution for the mutilated or
defaced Security, or in lieu of and substitution for the Security so destroyed,
lost or stolen. In every case the applicant for a substitute Security shall
furnish to the Issuer and to the Trustee and any agent of the Issuer or the
Trustee such security or indemnity as may be required by them to indemnify and
defend and to save each of them harmless and, in every case of destruction, loss
or theft, evidence to their satisfaction of the destruction, loss or theft of
such Security and of the ownership thereof in the case of mutilation or
defacement shall surrender the Security to the Trustee or such agent.

      Upon the issuance of any substitute Security, the Issuer may require the
payment of a sum sufficient to cover any tax or other governmental charge that
may be imposed in relation thereto and any other expenses (including the fees
and expenses of the Trustee or its agent) connected therewith. In case any
Security which has matured or is about to mature or has been called for
redemption in full shall become mutilated or defaced or be destroyed, lost or
stolen, the Issuer may instead of issuing a substitute Security, pay or
authorize the payment of the same (without surrender thereof except in the case
of a mutilated or defaced Security), if the applicant for such payment shall
furnish to the Issuer and the Trustee and any agent of the Issuer or the Trustee
such security or indemnity as any of them may require to save each of them
harmless, and, in every case of destruction, loss or theft, the applicant shall
also furnish to the Issuer and the Trustee and any agent of the Issuer or the
Trustee evidence to their satisfaction of the destruction, loss or theft of such
Security and of the ownership thereof.

      Every substitute Security of any series issued pursuant to the provisions
of this section by virtue of the fact that any such Security is destroyed, lost
or stolen shall constitute an additional contractual obligation of the Issuer,
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 (but shall be
subject to all the limitations of rights set forth in) this Indenture equally
and proportionately with any and all other Securities of such series duly
authenticated and delivered hereunder. All Securities shall be held and owned
upon the express condition that, to the extent permitted by law, the foregoing
provisions are exclusive with respect to the replacement or payment of
mutilated, defaced or destroyed, lost or stolen

                                       13
<PAGE>

Securities and shall preclude any and all other rights or remedies
notwithstanding any law or statute existing or hereafter enacted to the contrary
with respect to the replacement or payment of negotiable instruments or other
securities without their surrender.

      Section 2.10. Cancellation of Securities. All Securities surrendered for
payment, redemption, registration of transfer or exchange, or for credit against
any payment in respect of a sinking or analogous fund, if surrendered to the
Issuer or any agent of the Issuer or the Trustee, shall be delivered to the
Trustee for cancellation or, if surrendered to the Trustee, shall be cancelled
by it; and no Securities shall be issued in lieu thereof except as expressly
permitted by any of the provisions of this Indenture. The Trustee shall destroy
canceled Securities held by it and deliver a certificate of destruction to the
Issuer. If the Issuer shall acquire any of the Securities, such acquisition
shall not operate as a redemption or satisfaction of the indebtedness
represented by such Securities unless and until the same are delivered to the
Trustee for cancellation.

      Section 2.11. Temporary Securities. Pending the preparation of definitive
Securities for any series, the Issuer may execute and the Trustee shall
authenticate and deliver temporary Securities for such series (printed,
lithographed, typewritten or otherwise reproduced, in each case in form
satisfactory to the Trustee). Temporary Securities of any series shall be
issuable as registered Securities without coupons, of any authorized
denomination, and substantially in the form of the definitive Securities of such
series but with such omissions, insertions and variations as may be appropriate
for temporary Securities, all as may be determined by the Issuer with the
concurrence of the Trustee. Temporary Securities may contain such reference to
any provisions of this Indenture as may be appropriate. Every temporary Security
shall be executed by the Issuer and be authenticated by the Trustee upon the
same conditions and in substantially the same manner, and with like effect, as
the definitive Securities. Without unreasonable delay the Issuer shall execute
and shall furnish definitive Securities of such series and thereupon temporary
Securities of such series may be surrendered in exchange therefor without charge
at each office or agency to be maintained by the Issuer for that purpose
pursuant to Section 3.02, and the Trustee shall authenticate and deliver in
exchange for such temporary Securities of such series a like aggregate principal
amount of definitive Securities of the same series of authorized denominations.
Until so exchanged, the temporary Securities of any series shall be entitled to
the same benefits under this Indenture as definitive Securities of such series
unless otherwise established pursuant to Section 2.03.

                     COVENANTS OF THE ISSUER AND THE TRUSTEE

      Section 3.01. Payment of Principal and Interest. The Issuer covenants and
agrees for the benefit of each series of Securities that it will duly and
punctually pay or cause to be paid the principal of, and interest on, each of
the Securities of such series (together with any additional amounts payable
pursuant to the terms of such Securities) at the place or places, at the
respective times and in the manner provided in such Securities. Subject to any
other provisions that may be established pursuant to Section 2.03, the interest
on Securities (together with any additional amounts payable pursuant to the
terms of such Securities) shall be payable only to or upon the written order of
the Holders thereof and, at the option of the Issuer, may be paid by wire
transfer or by mailing checks for such interest payable to or upon the written
order of such Holders at their last addresses as they appear on the registry
books of the Issuer.

      Section 3.02. Offices for Payments, etc. So long as any of the Securities
remain outstanding, the Issuer will maintain in the Borough of Manhattan, The
City of New York, the following for each series: an office or agency (a) where
the Securities may be presented for payment, (b) where the Securities may be
presented for registration of transfer and for exchange as in this Indenture
provided and (c) where notices and demands to or upon the Issuer in respect of
the Securities or of this Indenture may be served. The Issuer will give to the
Trustee written notice of the location of any such office or agency and of any
change of location thereof. Unless otherwise specified in accordance with
Section 2.03, the Issuer hereby initially designates the Corporate Trust Office
of the Trustee, as the office to be maintained by it for each such purpose. In
case the Issuer shall fail to so designate or maintain any such office or agency
or shall fail to give such notice of the location or of any change in the
location thereof, presentations and demands may be made and notices may be
served at the Corporate Trust Office.

      The Issuer may from time to time designate one or more additional offices
or agencies where the Securities of a series may be presented for payment, where
the Securities of that series may be presented for exchange as provided in this
Indenture and pursuant to Section 2.03 and where the Securities of that series
may be presented for registration of transfer as provided in this Indenture, and
the Issuer may from time to time rescind any such designation, as the Issuer may
deem desirable or expedient; provided, however, that no such designation or
rescission shall in any manner relieve the Issuer of its obligation to maintain
the agencies provided for in this Section. The Issuer will give to the Trustee
prompt written notice of any such designation or rescission thereof.

      Section 3.03. Appointment to Fill a Vacancy in Office of Trustee. The
Issuer, whenever necessary to avoid or fill a vacancy in the office of Trustee,
will

                                       15
<PAGE>

appoint, in the manner provided in Section 5.09, a Trustee, so that there shall
at all times be a Trustee with respect to each series of Securities hereunder.

      Section 3.04. Paying Agents. Whenever the Issuer shall appoint a paying
agent other than the Trustee with respect to the Securities of any series, it
will cause such paying agent to execute and deliver to the Trustee an instrument
in which such agent shall agree with the Trustee, subject to the provisions of
this Section,

      (a) that it will hold all sums received by it as such agent for the
payment of the principal of or interest on the Securities of such series
(whether such sums have been paid to it by the Issuer or by any other obligor on
the Securities of such series) in trust for the benefit of the holders of the
Securities of such series or of the Trustee,

      (b) that it will give the Trustee notice of any failure by the Issuer (or
by any other obligor on the Securities of such series) to make any payment of
the principal of or interest on the Securities of such series when the same
shall be due and payable, and

      (c) that it will pay any such sums so held in trust by it to the Trustee
upon the Trustee's written request at any time during the continuance of the
failure referred to in clause 3.04(b) above.

      The Issuer will, on or prior to each due date of the principal of or
interest on the Securities of such series, deposit with the paying agent a sum
sufficient to pay such principal or interest so becoming due, and (unless such
paying agent is the Trustee) the Issuer will promptly notify the Trustee of any
failure to take such action.

      If the Issuer shall act as its own paying agent with respect to the
Securities of any Series, it will, on or before each due date of the principal
of or interest on the Securities of such series, set aside, segregate and hold
in trust for the benefit of the holders of the Securities of such series a sum
sufficient to pay such principal or interest so becoming due. The Issuer will
promptly notify the Trustee of any failure to take such action.

      Anything in this section to the contrary notwithstanding, the Issuer may
at any time, for the purpose of obtaining a satisfaction and discharge with
respect to one or more or all series of Securities hereunder, or for any other
reason, pay or cause to be paid to the Trustee all sums held in trust for any
such series by the Issuer or any paying agent hereunder, as required by this
Section, such sums to be held by the Trustee upon the trusts herein contained.

                                       16
<PAGE>

      Anything in this section to the contrary notwithstanding, the agreement to
hold sums in trust as provided in this section is subject to the provisions of
Section 9.03 and 9.04.

      Section 3.05. Certificate of the Issuer. The Issuer will furnish to the
Trustee on or before [__] in each year (beginning with [__]) a brief certificate
(which need not comply with Section 10.05) from the principal executive,
financial or accounting officer of the Issuer as to his or her knowledge of the
Issuer's compliance with all conditions and covenants under the Indenture (such
compliance to be determined without regard to any period of grace or requirement
of notice provided under the Indenture). If any Securities are guaranteed by a
guarantor, the guarantor shall also provide such certificates as are required by
this Section.

      Section 3.06. Securityholders Lists. If and so long as the Trustee shall
not be the Security registrar for the Securities of any series, the Issuer will
furnish or cause to be furnished to the Trustee a list in such form as the
Trustee may reasonably require of the names and addresses of the holders of the
Securities of such series pursuant to Section 312 of the Trust Indenture Act of
1939 (a) semi-annually not more than 15 days after each record date for the
payment of interest on such Securities, as hereinabove specified, as of such
record date and on dates to be determined pursuant to Section 2.03 for
non-interest bearing securities in each year, and (b) at such other times as the
Trustee may request in writing, within thirty days after receipt by the Issuer
of any such request as of a date not more than 15 days prior to the time such
information is furnished.

      Section 3.07. Reports by the Issuer. The Issuer covenants to file with the
Trustee, within 15 days after the Issuer is required to file the same with the
Commission, copies of the annual reports and of the information, documents, and
other reports that the Issuer may be required to file with the Commission
pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934.

      Section 3.08. Reports by the Trustee. Any Trustee's report required under
Section 313(a) of the Trust Indenture Act of 1939 shall be transmitted on or
before July 15 in each year following the date hereof, so long as any Securities
are outstanding hereunder, and shall be dated as of a date convenient to the
Trustee no more than 60 nor less than 45 days prior thereto.

      such guarantor and such decree or order shall remain unstayed and in
      effect for a period of 60 consecutive days; or

            (iii) a final and non-appealable order appointing a custodian,

commencement of any insolvency proceedings against it, or the filing by the
Issuer or such guarantor of a petition or answer or consent seeking
reorganization, arrangement, adjustment or composition of the Issuer or relief
under any applicable law, or the consent by the Issuer or such guarantor to the
filing of such petition or to the appointment of or taking possession by a
custodian, receiver, liquidator, assignee, trustee or similar official of the
Issuer or such guarantor or any substantial part of the property of the Issuer
or such guarantor or the making by the Issuer or such guarantor of an assignment
for the benefit of creditors, or the taking of corporate action, including the

furtherance of any such action; or

      (e) any other Event of Default provided in the supplemental indenture or
resolution of the Board under which such series of Securities is issued or in
the form of Security for such series.

      Unless otherwise set forth in any applicable supplemental indenture, if an
Event of Default described in clauses 4.01(a), 4.01(b), or 4.01(e) above (if the
Event of Default under clauses 4.01(b) or 4.01(e) is with respect to less than
all series of Securities then Outstanding) occurs and is continuing, then, and
in each and every such case, except for any series the principal of which shall
have already become due and payable, either the Trustee or the holders of not
less than 25% in aggregate principal amount of the Securities of all series
affected thereby then Outstanding hereunder (treated as one class) by notice in
writing to the Issuer (and to the Trustee if given by Securityholders), may
declare the entire principal (or, if the Securities of any such affected series
are Original Issue Discount Securities, such portion of the principal amount as
may be specified in the terms of such series) of all Securities of such affected
series and the interest accrued thereon, if any, to be due and payable
immediately, and upon any such declaration the same shall become immediately due
and payable. Unless otherwise set forth in any applicable supplemental
indenture, if an Event of Default described in clauses 4.01(b) or 4.01(e) (if
the Event of Default under clauses 4.01(b) or 4.01(e) is with respect to all
series of Securities at the time Outstanding) occurs and is continuing, then and
in each and every such case, unless the principal of all the Securities shall
have already become due and payable, either the Trustee or the holders of not
less than 25% in aggregate principal amount of all the then Outstanding
Securities hereunder (treated as one class) for which any applicable
supplemental indenture does not prevent acceleration under the relevant
circumstances, by notice in writing to the Issuer and the Guarantor (and to the
Trustee if given by Securityholders), may declare the entire principal (or, if
any Securities are Original Issue Discount Securities, such portion of the
principal as may be specified in the terms thereof) of all the Securities then
Outstanding and interest accrued thereon, if any, to be due and payable
immediately, and upon any such declaration the same shall become immediately due
and payable. Unless otherwise set forth in any applicable supplemental
indenture, if an Event of Default described in clauses 4.01(c) or 4.01(d), then
the principal and accrued and

                                       19
<PAGE>

unpaid interest, and premium of any, with respect to any Securities then
Outstanding shall ipso facto become and be immediately due and payable without
any declaration or other act on the part of the Trustee or any Holder.

      The foregoing provisions, however, are subject to the condition that if,
at any time after the principal (or, if the Securities are Original Issue
Discount Securities, such portion of the principal as may be specified in the
terms thereof) of the Securities of any series (or of all the Securities, as the
case may be) shall have been so declared due and payable, and before any
judgment or decree for the payment of the moneys due shall have been obtained or
entered as hereinafter provided, the Issuer shall pay or shall deposit with the
Trustee a sum sufficient to pay all matured installments of interest upon all
the Securities of such series (or of all the Securities, as the case may be) and
the principal of any and all Securities of such series (or of all the
Securities, as the case may be) which shall have become due otherwise than by
acceleration (with interest upon such principal and, to the extent that payment
of such interest is enforceable under applicable law, on overdue installments of
interest, at the same rate as the rate of interest or Yield to Maturity (in the
case of Original Issue Discount Securities) specified in the Securities of such
series (or at the respective rates of interest or Yields to Maturity of all the
Securities, as the case may be) to the date of such payment or deposit) and such
amount as shall be sufficient to cover reasonable compensation to the Trustee,
its agents, attorneys and counsel, and all other expenses and liabilities
incurred, and all advances made, by the Trustee except as a result of negligence
or bad faith, and if any and all Events of Default under the Indenture, other
than the non-payment of the principal of Securities which shall have become due
by acceleration, shall have been cured, waived or otherwise remedied as provided
herein--then and in every such case the holders of a majority in aggregate
principal amount of all the Securities of each such series (or of all the
Securities, as the case may be), then Outstanding (in each case treated as one
class), by written notice to the Issuer and to the Trustee, may waive all
defaults with respect to each such series (or with respect to all the
Securities, as the case may be) and rescind and annul such declaration and its
consequences, but no such waiver or rescission and annulment shall extend to or
shall affect any subsequent default or shall impair any right consequent
thereon.

      For all purposes under this Indenture, if a portion of the principal of
any Original Issue Discount Securities shall have been accelerated and declared
due and payable pursuant to the provisions hereof, then, from and after such
declaration, unless such declaration has been rescinded and annulled, the
principal amount of such Original Issue Discount Securities shall be deemed, for
all purposes hereunder, to be such portion of the principal thereof as shall be
due and payable as a result of such acceleration, and payment of such portion of
the principal thereof as shall be due and payable as a result of such
acceleration, together with interest, if any, thereon and all other amounts
owing thereunder, shall constitute payment in full of such Original Issue
Discount Securities.

      Section 4.02. Collection of Indebtedness by Trustee; Trustee May Prove
Debt. The Issuer covenants that (a) in case default shall be made in the payment
of any installment of interest on any of the Securities of any series when such
interest shall have become due and payable, and such default shall have
continued for a period of 30 days or (b) in case default shall be made in the
payment of all or any part of the principal of any of the Securities of any
series when the same shall have become due and payable, whether upon maturity of
the Securities of such series or upon any redemption or by declaration or
otherwise--then upon demand of the Trustee, the Issuer will pay to the Trustee
for the benefit of the Holders of the Securities of such series the whole amount
that then shall have become due and payable on all Securities of series for
principal or interest, as the case may be (with interest to the date of such
payment upon the overdue principal and, to the extent that payment of such
interest is enforceable under applicable law, on overdue installments of
interest at the same rate as the rate of interest or Yield to Maturity (in the
case of Original Issue Discount Securities) specified in the Securities of such
series); and in addition thereto, such further amount as shall be sufficient to
cover the costs and expenses of collection, including reasonable compensation to
the Trustee and each predecessor Trustee, their respective agents, attorneys and
counsel, and any expenses and liabilities incurred, and all advances made, by
the Trustee and each predecessor Trustee except as a result of its negligence or
bad faith.

      Until such demand is made by the Trustee, the Issuer may pay the principal
of and interest on the Securities of any series to the registered holders,
whether or not the principal of and interest on the Securities of such series be
overdue.

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

      In case there shall be pending proceedings relative to the Issuer or any
other obligor upon the Securities under Title 11 of the United States Code or
any other applicable Federal or state bankruptcy, insolvency or other similar
law, or in case a receiver, assignee or trustee in bankruptcy or reorganization,
liquidator, sequestrator or similar official shall have been appointed for or
taken possession of the Issuer or its property or such other obligor, or in case
of any other comparable judicial proceedings relative to the Issuer or other
obligor upon the Securities of any series, or to the creditors or property of
the Issuer or such other

                                       21
<PAGE>

obligor, the Trustee, irrespective of whether the principal of any Securities
shall then be due and payable as therein expressed or by declaration or
otherwise and irrespective of whether the Trustee shall have made any demand
pursuant to the provisions of this Section, shall be entitled and empowered, by
intervention in such proceedings or otherwise:

            (a) to file and prove a claim or claims for the whole amount of
      principal and interest (or, if the Securities of any series are Original
      Issue Discount Securities, such portion of the principal amount as may be
      specified in the terms of such series) owing and unpaid in respect of the
      Securities of any series, and to file such other papers or documents as
      may be necessary or advisable in order to have the claims of the Trustee
      (including any claim for reasonable compensation to the Trustee and each
      predecessor Trustee, and their respective agents, attorneys and counsel,
      and for reimbursement of all expenses and liabilities incurred, and all
      advances made, by the Trustee and each predecessor Trustee, except as a
      result of negligence or bad faith) and of the Securityholders allowed in
      any judicial proceedings relative to the Issuer or other obligor upon the
      Securities of any series, or to the creditors or property of the Issuer or
      such other obligor,

            (b) unless prohibited by applicable law and regulations, to vote on
      behalf of the holders of the Securities of any series in any election of a
      trustee or a standby trustee in arrangement, reorganization, liquidation
      or other bankruptcy or insolvency proceedings or person performing similar
      functions in comparable proceedings, and

            (c) to collect and receive any moneys or other property payable or
      deliverable on any such claims, and to distribute all amounts received
      with respect to the claims of the Securityholders and of the Trustee on
      their behalf; and any trustee, receiver, or liquidator, custodian or other
      similar official is hereby authorized by each of the Securityholders to
      make payments to the Trustee, and, in the event that the Trustee shall
      consent to the making of payments directly to the Securityholders, to pay
      to the Trustee such amounts as shall be sufficient to cover reasonable
      compensation to the Trustee, each predecessor Trustee and their respective
      agents, attorneys and counsel, and all other expenses and liabilities
      incurred, and all advances made, by the Trustee and each predecessor
      Trustee except as a result of negligence or bad faith.

      Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or vote for or accept or adopt on behalf of any
Securityholder any plan or reorganization, arrangement, adjustment or
composition affecting the Securities of any series or the rights of any Holder
thereof, or to authorize the Trustee to vote in respect of the claim of any

                                       22
<PAGE>

Securityholder in any such proceeding except, as aforesaid, to vote for the
election of a trustee in bankruptcy or similar person.

      All rights of action and of asserting claims under this Indenture, or
under any of the Securities, may be enforced by the Trustee without the
possession of any of the Securities or the production thereof on any trial or
other proceedings relative thereto, and any such action or proceedings
instituted by the Trustee shall be brought in its own name as trustee of an
express trust, and any recovery of judgment, subject to the payment of the
expenses, disbursements and compensation of the Trustee, each predecessor
Trustee and their respective agents and attorneys, shall be for the ratable
benefit of the holders of the Securities in respect of which such action was
taken.

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

      Section 4.03. Application of Proceeds. Any moneys collected by the Trustee
pursuant to this Article in respect of any series shall be applied in the
following order at the date or dates fixed by the Trustee and, in case of the
distribution of such moneys on account of principal or interest, upon
presentation of the several Securities in respect of which monies have been
collected and stamping (or otherwise noting) thereon the payment, or issuing
Securities of such series in reduced principal amounts in exchange for the
presented Securities of like series if only partially paid, or upon surrender
thereof if fully paid:

            FIRST: To the payment of costs and expenses applicable to such
      series in respect of which monies have been collected, including
      reasonable compensation to the Trustee and each predecessor Trustee and
      their respective agents and attorneys and of all expenses and liabilities
      incurred, and all advances made, by the Trustee and each predecessor
      Trustee except as a result of negligence or bad faith;

            SECOND: In case the principal of the Securities of such series in
      respect of which moneys have been collected shall not have become and be
      then due and payable, to the payment of interest on the Securities of such
      series in default in the order of the maturity of the installments of such
      interest, with interest (to the extent that such interest has been
      collected by the Trustee) upon the overdue installments of interest at the
      same rate as the rate of interest or Yield to Maturity (in the case of
      Original Issue Discount Securities) specified in such Securities, such
      payments to be made ratably to the persons entitled thereto, without
      discrimination or preference;

                                       23
<PAGE>

            THIRD: In case the principal of the Securities of such series in
      respect of which moneys have been collected shall have become and shall be
      then due and payable, to the payment of the whole amount then owing and
      unpaid upon all the Securities of such series for principal and interest,
      with interest upon the overdue principal, and (to the extent that such
      interest has been collected by the Trustee) upon overdue installments of
      interest at the same rate as the rate of interest or Yield to Maturity (in
      the case of Original Issue Discount Securities) specified in the
      Securities of such series; and in case such moneys shall be insufficient
      to pay in full the whole amount so due and unpaid upon the Securities of
      such series, then to the payment of such principal and interest or Yield
      to Maturity, without preference or priority of principal over interest or
      Yield to Maturity, or of interest or Yield to Maturity over principal, or
      of any installment of interest over any other installment of interest, or
      of any Security of such series over any other Security of such series,
      ratably to the aggregate of such principal and accrued and unpaid interest
      or Yield to Maturity; and

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

      Section 4.04. Suits for Enforcement. In case an Event of Default has
occurred, has not been waived and is continuing, the Trustee may in its
discretion proceed to protect and enforce the rights vested in it by this
Indenture by such appropriate judicial proceedings as the Trustee shall deem
most effectual to protect and enforce any of such rights, either at law or in
equity or in bankruptcy or otherwise, whether for the specific enforcement of
any covenant or agreement contained in this Indenture or in aid of the exercise
of any power granted in this Indenture or to enforce any other legal or
equitable right vested in the Trustee by this Indenture or by law.

      Section 4.05. Restoration of Rights on Abandonment of Proceeding. In case
the Trustee shall have proceeded to enforce any right under this Indenture and
such proceedings shall have been discontinued or abandoned for any reason, or
shall have been determined adversely to the Trustee, then and in every such case
the Issuer and the Trustee shall be restored respectively to their former
positions and rights hereunder, and all rights, remedies and powers of the
Issuer, the Trustee and the Securityholders shall continue as though no such
proceedings had been taken.

      Section 4.06. Limitations on Suits by Securityholder. No holder of any
Security of any series shall have any right by virtue or by availing of any
provision of this Indenture to institute any action or proceeding at law or in
equity or in bankruptcy or otherwise upon or under or with respect to this
Indenture, or for the appointment of a trustee, receiver, liquidator, custodian
or other similar official or for any other remedy hereunder, unless such Holder
previously shall

                                       24
<PAGE>

have given to the Trustee written notice of default and of the continuance
thereof, as hereinbefore provided, and unless also the Holders of not less than
25% in aggregate principal amount of the Securities of each affected series then
Outstanding (treated as a single class) shall have made written request upon the
Trustee to institute such action or proceedings in its own name as trustee
hereunder and shall have offered to the Trustee such reasonable indemnity as it
may require against the costs, expenses and liabilities to be incurred therein
or thereby and the Trustee for 60 days after its receipt of such notice, request
and offer of indemnity shall have failed to institute any such action or
proceeding and no direction inconsistent with such written request shall have
been given to the Trustee pursuant to Section 4.09; it being understood and
intended, and being expressly covenanted by the taker and Holder of every
Security with every other taker and Holder and the Trustee, that no one or more
Holders of Securities of any series shall have any right in any manner whatever
by virtue or by availing of any provision of this Indenture to affect, disturb
or prejudice the rights of any other such Holder of Securities, or to obtain or
seek to obtain priority over or preference to any other such Holder or to
enforce any right under this Indenture, except in the manner herein provided and
for the equal, ratable and common benefit of all Holders of Securities of the
applicable series. For the protection and enforcement of the provisions of this
Section, each and every Securityholder and the Trustee shall be entitled to such
relief as can be given either at law or in equity.

      Section 4.07. Unconditional Right of Securityholders to Institute Certain
Suits. Notwithstanding any other provision in this Indenture and any provision
of any Security, the right of any Holder of any Security to receive payment of
the principal of and interest on such Security on or after the respective due
dates expressed in such Security, or to institute suit for the enforcement of
any such payment on or after such respective dates, shall not be impaired or
affected without the consent of such Holder.

      Section 4.08. Powers and Remedies Cumulative; Delay or Omission Not Waiver
of Default. Except as provided in Section 4.06, no right or remedy herein
conferred upon or reserved to the Trustee or to the Securityholders 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.

      No delay or omission of the Trustee or of any Securityholder to exercise
any right or power accruing upon any Event of Default occurring and continuing
as aforesaid shall impair any such right or power or shall be construed to be a
waiver of any such Event of Default or an acquiescence therein; and, subject to
Section 4.06, every power and remedy given by this Indenture or by law to the

                                       25
<PAGE>

Trustee or to the Securityholders may be exercised from time to time, and as
often as shall be deemed expedient, by the Trustee or by the Securityholders.

      Section 4.09. Control by Securityholders. The Holders of a majority in
aggregate principal amount of the Securities of each series affected (with all
such series voting as a single class) at the time Outstanding 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 by this Indenture;
provided that such direction shall not be otherwise than in accordance with law
and the provisions of this Indenture and provided further that (subject to the
provisions of Section 5.01) the Trustee shall have the right to decline to
follow any such direction if the Trustee, being advised by counsel, shall
determine that the action or proceeding so directed may not lawfully be taken or
if the Trustee in good faith by its board of directors, the executive committee,
or a trust committee of directors or Responsible Officers of the Trustee shall
determine that the action or proceedings so directed would involve the Trustee
in personal liability or if the Trustee in good faith shall so determine that
the actions or forebearances specified in or pursuant to such direction would be
unduly prejudicial to the interests of Holders of the Securities of all series
so affected not joining in the giving of said direction, it being understood
that (subject to Section 5.01) the Trustee shall have no duty to ascertain
whether or not such actions or forebearances are unduly prejudicial to such
Holders.

      Nothing in this Indenture shall impair the right of the Trustee in its
discretion to take any action deemed proper by the Trustee and which is not
inconsistent with such direction or directions by Securityholders.

      Section 4.10. Waiver of Past Defaults. Prior to the acceleration of the
maturity of any Securities as provided in Section 4.01, the Holders of a
majority in aggregate principal amount of the Securities of all series at the
time Outstanding with respect to which an Event of Default shall have occurred
and be continuing (voting as a single class) may on behalf of the Holders of all
such Securities waive any past default or Event of Default described in Section
4.01 and its consequences, except a default in respect of a covenant or
provision hereof which cannot be modified or amended without the consent of the
Holder of each Security affected. In the case of any such waiver, the Issuer,
the Guarantor, the Trustee and the Holders of all such Securities shall be
restored to their former positions and rights hereunder, respectively; but no
such waiver shall extend to any subsequent or other default or impair any right
consequent thereon.

      Upon any such waiver, such default shall cease to exist and be deemed to
have been cured and not to have occurred, and any Event of Default arising
therefrom shall be deemed to have been cured, and not to have occurred for every

                                       26
<PAGE>

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 4.11. Trustee to Give Notice of Default, But May Withhold in
Certain Circumstances. The Trustee shall give to the Securityholders of any
series, as the names and addresses of such Holders appear on the registry books,
notice by mail of all defaults known to the Trustee which have occurred with
respect to such series, such notice to be transmitted within 90 days after the
occurrence thereof, unless such defaults shall have been cured before the giving
of such notice (the term "default" or "defaults" for the purposes of this
section being hereby defined to mean any event or condition which is, or with
notice or lapse of time or both would become, an Event of Default); provided
that, except in the case of default in the payment of the principal of or
interest on any of the Securities of such series, or in the payment of any
sinking or purchase fund installment with respect to the Securities of such
series, the Trustee shall be protected in withholding such notice if and so long
as the board of directors, the executive committee, or a trust committee of
directors or trustees and/or Responsible Officers of the Trustee in good faith
determines that the withholding of such notice is in the interests of the
Securityholders of such series.

      Section 4.12. Right of Court to Require Filing of Undertaking to Pay
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 in any suit against the Trustee for any action taken, suffered
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 Securityholder or group of
Securityholders of any series holding in the aggregate more than 10% in
aggregate principal amount of the Securities of such series, or, in the case of
any suit relating to or arising under clauses 4.01(b) or 4.01(e) (if the suit
relates to Securities of more than one but less than all series), 10% in
aggregate principal amount of Securities Outstanding affected thereby, or in the
case of any suit relating to or arising under clauses 4.01(b) or 4.01(e) (if the
suit relates to all the Securities then Outstanding), 4.01(c) or 4.01(d), 10% in
aggregate principal amount of all Securities Outstanding, or to any suit
instituted by any Securityholder for the enforcement of the payment of the
principal of or interest on any Security on or after the due date expressed in
such Security.

                             CONCERNING THE TRUSTEE

      Section 5.01. Duties and Responsibilities of the Trustee; During Default;
Prior to Default. With respect to the Holders of any series of Securities
issued hereunder, the Trustee, prior to the occurrence of an Event of Default
with respect to the Securities of a particular series and after the curing or
waiving of all Events of Default which may have occurred with respect to such
series, undertakes to perform such duties and only such duties as are
specifically set forth in this Indenture. In case an Event of Default with
respect to the Securities of a series has occurred (which has not been cured or
waived) the Trustee shall exercise with respect to such series of Securities
such of the rights and powers vested in it by this Indenture, and use the same
degree of care and skill in their exercise, as a prudent person would exercise
or use under the circumstances in the conduct of his or her own affairs.

      No provision of this Indenture shall be construed to relieve the Trustee
from liability for its own negligent action, its own negligent failure to act or
its own willful misconduct, except that

      (a) prior to the occurrence of an Event of Default with respect to the
Securities of any series and after the curing or waiving of all such Events of
Default with respect to such series which may have occurred:

            (i) the duties and obligations of the Trustee with respect to the
      Securities of any Series shall be determined solely by the express
      provisions of this Indenture, and the Trustee shall not be liable except
      for the performance of such duties and obligations as are specifically set
      forth in this Indenture, and no implied covenants or obligations shall be
      read into this Indenture against the Trustee; and

            (ii) in the absence of bad faith on the part of the Trustee, the
      Trustee may conclusively rely, as to the truth of the statements and the
      correctness of the opinions expressed therein, upon any statements,
      certificates or opinions furnished to the Trustee and conforming to the
      requirements of this Indenture; but in the case of any such statements,
      certificates or opinions which by any provision hereof are specifically
      required to be furnished to the Trustee, the Trustee shall be under a duty
      to examine the same to determine whether or not they conform to the
      requirements of this Indenture;

      (b) the Trustee shall not be liable for any error of judgment made in good
faith by a Responsible Officer or Responsible Officers of the Trustee, unless it
shall be proved that the Trustee was negligent in ascertaining the pertinent
facts; and

                                       28
<PAGE>

      (c) the Trustee shall not be liable with respect to any action taken or
omitted to be taken by it in good faith in accordance with the direction of the
holders pursuant to Section 4.09 relating to the time, method and place of
conducting any proceeding for any remedy available to the Trustee, or exercising
any trust or power conferred upon the Trustee, under this Indenture.

      None of the provisions contained in this Indenture shall require the
Trustee to expend or risk its own funds or otherwise incur personal financial
liability in the performance of any of its duties or in the exercise of any of
its rights or powers, if there shall be reasonable ground for believing that the
repayment of such funds or adequate indemnity against such liability is not
reasonably assured to it.

      The provisions of this Section 5.01 are in furtherance of and subject to
Sections 315 and 316 of the Trust Indenture Act of 1939.

      Section 5.02. Certain Rights of the Trustee. In furtherance of and subject
to the Trust Indenture Act of 1939, and subject to Section 5.01:

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

      (b) any request, direction, order or demand of the Issuer mentioned herein
shall be sufficiently evidenced by an Officers' Certificate (unless other
evidence in respect thereof be herein specifically prescribed); and any
resolution of the Board may be evidenced to the Trustee by a copy thereof
certified by the secretary or an assistant secretary of the Issuer;

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

      (d) the Trustee shall be under no obligation to exercise any of the trusts
or powers vested in it by this Indenture at the request, order or direction of
any of the Securityholders pursuant to the provisions of this Indenture, unless
such Securityholders shall have offered to the Trustee reasonable security or
indemnity against the costs, expenses and liabilities which might be incurred
therein or thereby;

                                       29
<PAGE>

      (e) the Trustee shall not be liable for any action taken or omitted by it
in good faith and believed by it to be authorized or within the discretion,
rights or powers conferred upon it by this Indenture;

      (f) prior to the occurrence of an Event of Default hereunder and after the
curing or waiving of all Events of Default, 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, consent,
order, approval, appraisal, bond, debenture, note, coupon, security, or other
paper or document unless requested in writing so to do by the holders of not
less than a majority in aggregate principal amount of the Securities of all
series affected then outstanding; provided that, if the payment within a
reasonable time to the Trustee of the costs, expenses or liabilities likely to
be incurred by it in the making of such investigation is, in the opinion of the
Trustee, not reasonably assured to the Trustee by the security afforded to it by
the terms of this Indenture, the Trustee may require reasonable indemnity
against such expenses or liabilities as a condition to proceeding; the
reasonable expenses of every such investigation shall be paid by the Issuer or,
if paid by the Trustee or any predecessor trustee, shall be repaid by the Issuer
upon demand; and

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

      Section 5.03. Trustee Not Responsible for Recitals, Disposition of
Securities or Application of Proceeds Thereof. The recitals contained herein and
in the Securities, except the Trustee's certificates of authentication, shall be
taken as the statements of the Issuer, and the Trustee assumes no responsibility
for the correctness of the same. The Trustee makes no representation as to the
validity or sufficiency of this Indenture or of the Securities. The Trustee
shall not be accountable for the use or application by the Issuer of any of the
Securities or of the proceeds thereof.

      Section 5.04. Trustee and Agents May Hold Securities; Collections, etc.
The Trustee or any agent of the Issuer or the Trustee, in its individual or any
other capacity, may become the owner or pledgee of Securities with the same
rights it would have if it were not the Trustee or such agent and may otherwise
deal with the Issuer and receive, collect, hold and retain collections from the
Issuer with the same rights it would have if it were not the Trustee or such
agent.

      Section 5.05. Moneys Held by Trustee. Subject to the provisions of Section
9.04 hereof, all moneys received by the Trustee shall, until used or applied as
herein provided, be held in trust for the purposes for which they were

                                       30
<PAGE>

received, but need not be segregated from other funds except to the extent
required by mandatory provisions of law. Neither the Trustee nor any agent of
the Issuer or the Trustee shall be under any liability for interest on any
moneys received by it hereunder.

      Section 5.06. Compensation and Indemnification of Trustee and its Prior
Claim. The Issuer covenants and agrees to pay to the Trustee from time to time,
and the Trustee shall be entitled to, reasonable compensation (which shall not
be limited by any provision of law in regard to the compensation of a trustee of
an express trust) and the Issuer covenants and agrees to pay or reimburse the
Trustee and each predecessor Trustee upon its request for all reasonable
expenses, disbursements and advances incurred or made by or on behalf of it in
accordance with any of the provisions of this Indenture (including the
reasonable compensation and the expenses and disbursements of its counsel and of
all agents and other persons not regularly in its employ) except to the extent
any such expense, disbursement or advance may arise from its negligence or bad
faith. The Issuer also covenants to indemnify the Trustee and each predecessor
Trustee for, and to hold it harmless against, any loss, liability or expense
arising out of or in connection with the acceptance or administration of this
Indenture or the trusts hereunder and the performance of its duties hereunder,
including the costs and expenses of defending itself against or investigating
any claim of liability in the premises, except to the extent such loss liability
or expense is due to the negligence or bad faith of the Trustee, its agents or
employees or such predecessor Trustee. The obligations of the Issuer under this
section to compensate and indemnify the Trustee and each predecessor Trustee and
to pay or reimburse the Trustee and each predecessor Trustee for expenses,
disbursements and advances shall constitute additional indebtedness hereunder
and shall survive the satisfaction and discharge of this Indenture. Such
additional indebtedness shall be a senior claim to that of the Securities upon
all property and funds held or collected by the Trustee as such, except funds
held in trust for the benefit of the holders of particular Securities, and the
Securities are hereby subordinated to such senior claim.

      Section 5.07. Right of Trustee to Reply on Officers' Certificate, etc.
Subject to Sections 5.01 and 5.02, whenever in the administration of the trusts
of this Indenture the Trustee shall deem it necessary or desirable that a matter
be proved or established prior to taking or suffering or omitting any action
hereunder, such matter (unless other evidence in respect thereof be herein
specifically prescribed) may, in the absence of negligence or bad faith on the
part of the Trustee, be deemed to be conclusively proved and established by an
Officers' Certificate delivered to the Trustee, and such certificate, in the
absence of negligence or bad faith on the part of the Trustee, shall be full
warrant to the Trustee for any action taken, suffered or omitted by it under the
provisions of this Indenture upon the faith thereof.

                                       31
<PAGE>

      Section 5.08. Persons Eligible for Appointment as Trustee. The Trustee for
each series of Securities hereunder shall at all times be a corporation
organized and doing business under the laws of the United States of America or
the District of Columbia having a combined capital and surplus of at least
$50,000,000, and which is eligible in accordance with the provisions of Section
310(a) of the Trust Indenture Act of 1939. If such corporation publishes reports
of condition at least annually, pursuant to law or to the requirements of a
Federal, State or District of Columbia supervising or examining authority, then
for the purposes of this Section, the combined capital and surplus of such
corporation shall be deemed to be its combined capital and surplus as set forth
in its most recent report of condition so published.

      Section 5.09. Resignation and Removal; Appointment of Successor Trustee.
(a) The Trustee, or any trustee or trustees hereafter appointed, may at any time
resign with respect to one or more or all series of Securities by giving written
notice of resignation to the Issuer and by mailing notice thereof by first class
mail to Holders of the applicable series of Securities at their last addresses
as they shall appear on the Security register. Upon receiving such notice of
resignation, the Issuer shall promptly appoint a successor trustee or trustees
with respect to the applicable series by written instrument in duplicate,
executed by authority of the Board, one copy of which instrument shall be
delivered to the resigning Trustee and one copy to the successor trustee or
trustees. If no successor trustee shall have been so appointed with respect to
any series and have accepted appointment within 30 days after the mailing of
such notice of resignation, the resigning trustee may petition any court of
competent jurisdiction for the appointment of a successor trustee, or any
Securityholder who has been a bona fide Holder of a Security or Securities of
the applicable series for at least six months may, subject to the provisions of
Section 4.12, on behalf of himself and all others similarly situated, petition
any such court for the appointment of a successor trustee. Such court may
thereupon, after such notice, if any, as it may deem proper and prescribe,
appoint a successor trustee.

      (b) In case at any time any of the following shall occur:

            (i) the Trustee shall fail to comply with the provisions of Section
      310(b) of the Trust Indenture Act of 1939 with respect to any series of
      Securities after written request therefor by the Issuer or by any
      Securityholder who has been a bona fide Holder of a Security or Securities
      of such series for at least six months; or

            (ii) the Trustee shall cease to be eligible in accordance with the
      provisions of Section 310(a) of the Trust Indenture Act of 1939 and shall
      fail to resign after written request therefor by the Issuer or by any
      Securityholder; or

                                       32
<PAGE>

            (iii) the Trustee shall become incapable of acting with respect to
      any series of Securities, or shall be adjudged a bankrupt or insolvent, or
      a receiver or liquidator 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, the Issuer may remove the Trustee with respect to the
applicable series of Securities and appoint a successor trustee for such series
by written instrument, in duplicate, executed by order of the Board of the
Issuer, one copy of which instrument shall be delivered to the Trustee so
removed and one copy to the successor trustee, or, subject to Section 315(e) of
the Trust Indenture Act of 1939, any Securityholder who has been a bona fide
Holder of a Security or Securities 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 removal of the Trustee and the appointment of a
successor trustee with respect to such series. Such court may thereupon, after
such notice, if any, as it may deem proper and prescribe, remove the Trustee and
appoint a successor trustee.

      (c) The Holders of a majority in aggregate principal amount of the
Securities of each series at the time outstanding may at any time remove the
Trustee with respect to Securities of such series and appoint a successor
trustee with respect to the Securities of such series by delivering to the
Trustee so removed, to the successor trustee so appointed and to the Issuer the
evidence provided for in Section 6.01 of the action in that regard taken by the
Securityholders.

      (d) Any resignation or removal of the Trustee with respect to any series
and any appointment of a successor trustee with respect to such series pursuant
to any of the provisions of this Section 5.09 shall become effective upon
acceptance of appointment by the successor trustee as provided in Section 5.10.

      Section 5.10. Acceptance of Appointment By Successor Trustee. Any
successor trustee appointed as provided in Section 5.09 shall execute and
deliver to the Issuer and to its predecessor trustee an instrument accepting
such appointment hereunder, and thereupon the resignation or removal of the
predecessor trustee with respect to all or any applicable series shall become
effective and such successor trustee, without any further act, deed or
conveyance, shall become vested with all rights, powers, duties and obligations
with respect to such series of its predecessor hereunder, with like effect as if
originally named as trustee for such series hereunder; but, nevertheless, on the
written request of the Issuer or of the successor trustee, upon payment of its
charges then unpaid, the trustee ceasing to act shall, subject to Section 9.04,
pay over to the successor trustee all moneys at the time held by it hereunder
and shall execute and deliver an instrument transferring to such successor
trustee all such rights, powers, duties

                                       33
<PAGE>

and obligations. Upon request of any such successor trustee, the Issuer shall
execute any and all instruments in writing for more fully and certainly vesting
in and confirming to such successor trustee all such rights and powers. Any
trustee ceasing to act shall, nevertheless, retain a prior claim upon all
property or funds held or collected by such trustee to secure any amounts then
due it pursuant to the provisions of Section 5.06.

      If a successor trustee is appointed with respect to the Securities of one
or more (but not all) series, the Issuer, the predecessor Trustee and each
successor trustee with respect to the Securities of any applicable series shall
execute and deliver an indenture supplemental hereto which shall contain such
provisions as shall be deemed necessary or desirable to confirm that all the
rights, powers, trusts and duties of the predecessor Trustee with respect to the
Securities of any series as to which the predecessor Trustee is not retiring
shall continue to be vested in the predecessor Trustee, and 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 under separate
indentures.

      Upon acceptance of appointment by any successor trustee as provided in
this Section 5.10, the Issuer shall mail notice thereof by first-class mail to
the Holders of Securities of any series for which such successor trustee is
acting as trustee at their last addresses as they shall appear in the Security
register. If the acceptance of appointment is substantially contemporaneous with
the resignation, then the notice called for by the preceding sentence may be
combined with the notice called for by Section 5.09. If the Issuer fails to mail
such notice within ten days after acceptance of appointment by the successor
trustee, the successor trustee shall cause such notice to be mailed at the
expense of the Issuer.

      Section 5.11. Merger, Conversion, Consolidation or Succession to Business
of Trustee. 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 the corporate trust business of the Trustee, shall be
the successor of the Trustee hereunder, provided that such corporation shall be
eligible under the provisions of Section 5.08, without the execution or filing
of any paper or any further act on the part of any of the parties hereto,
anything herein to the contrary notwithstanding.

      In case at the time such successor to the Trustee shall succeed to the
trusts created by this Indenture any of the Securities of any series shall have
been authenticated but not delivered, any such successor to the Trustee may
adopt the certificate of authentication of any predecessor Trustee and deliver
such Securities

                                       34
<PAGE>

so authenticated; and, in case at that time any of the Securities of any series
shall not have been authenticated, any successor to the Trustee may authenticate
such Securities either in the name of any predecessor hereunder or in the name
of the successor Trustee; and in all such cases such certificate shall have the
full force which it is anywhere in the Securities of such series or in this
Indenture provided that the certificate of the Trustee shall have; provided,
that the right to adopt the certificate of authentication of any predecessor
Trustee or to authenticate Securities of any series in the name of any
predecessor Trustee shall apply only to its successor or successors by merger,
conversion or consolidation.

                                    ARTICLE 6
                         CONCERNING THE SECURITYHOLDERS

      Section 6.01. Evidence of Action Taken by Securityholders. 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 Securityholders 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 Securityholders 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 Sections 5.01 and 5.02) conclusive in favor of the Trustee and the
Issuer, if made in the manner provided in this Article.

      Section 6.02. Proof of Execution of Instruments and of Holding of
Securities; Record Date. Subject to Sections 5.01 and 5.02, the execution of any
instrument by a Securityholder 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. The holding of
Securities shall be proved by the Security register or by a certificate of the
registrar thereof. The Issuer may set a record date for purposes of determining
the identity of holders of Securities of any series entitled to vote or consent
to any action referred to in Section 6.01, which record date may be set at any
time or from time to time by notice to the Trustee, for any date or dates (in
the case of any adjournment or reconsideration) not more than 60 days nor less
than five days prior to the proposed date of such vote or consent, and
thereafter, notwithstanding any other provisions hereof, only holders of
Securities of such series of record on such record date shall be entitled to so
vote or give such consent or revoke such vote or consent.

      Section 6.03. Holders to be Treated as Owners. The Issuer, the Trustee and
any agent of the Issuer or the Trustee may deem and treat the person in whose

                                       35
<PAGE>

name any Security shall be registered upon the Security register for such series
as the absolute owner of such Security (whether or not such Security shall be
overdue and notwithstanding any notation of ownership or other writing thereon)
for the purpose of receiving payment of or on account of the principal of and,
subject to the provisions of this Indenture, interest on such Security and for
all other purposes; and neither the Issuer nor the Trustee nor any agent of the
Issuer or the Trustee shall be affected by any notice to the contrary. All such
payments so made to any such person, or upon his order, shall be valid, and, to
the extent of the sum or sums so paid, effectual to satisfy and discharge the
liability for moneys payable upon any such Security.

      Section 6.04. Securities Owned by Issuer Deemed Not Outstanding. In
determining whether the Holders of the requisite aggregate principal amount of
Outstanding Securities of any or all series have concurred in any direction,
consent or waiver under this Indenture, Securities which are owned by the Issuer
or any other obligor on the Securities with respect to which such determination
is being made or by any person directly or indirectly controlling or controlled
by or under direct or indirect common control with the Issuer or any other
obligor on the Securities with respect to which such determination is being made
shall be disregarded and deemed not to be Outstanding for the purpose of any
such determination, except that for the purpose of determining whether the
Trustee shall be protected in relying on any such direction, consent or waiver
only Securities which the Trustee knows are so owned shall be so disregarded.
Securities so owned which have been pledged in good faith may be regarded as
Outstanding if the pledgee establishes to the satisfaction of the Trustee the
pledgee's right so to act with respect to such Securities and that the pledgee
is not the Issuer or any other obligor upon the Securities or any person
directly or indirectly controlling or controlled by or under direct or indirect
common control with the Issuer or any other obligor on the Securities. In case
of a dispute as to such right, the advice of counsel shall be full protection in
respect of any decision made by the Trustee in accordance with such advice. Upon
request of the Trustee, the Issuer shall furnish to the Trustee promptly an
Officers' Certificate listing and identifying all Securities, if any, known by
the Issuer to be owned or held by or for the account of any of the
above-described persons; and, subject to Sections 5.01 and 5.02, the Trustee
shall be entitled to accept such Officers' Certificate as conclusive evidence of
the facts therein set forth and of the fact that all Securities not listed
therein are Outstanding for the purpose of any such determination.

      Section 6.05. Right of Revocation of Action Taken. At any time prior to
(but not after) the evidencing to the Trustee, as provided in Section 6.01, of
the taking of any action by the Holders of the percentage in aggregate principal
amount of the Securities of any or all series, as the case may be, specified in
this Indenture in connection with such action, any Holder of a Security the
serial number of which is shown by the evidence to be included among the serial

                                       36
<PAGE>

numbers of the Securities the Holders of which have consented to such action
may, by filing written notice at the Corporate Trust Office and upon proof of
holding as provided in this Article, revoke such action so far as concerns such
Security. Except as aforesaid any such action taken by the Holder of any
Security shall be conclusive and binding upon such Holder and upon all future
Holders and owners of such Security and of any Securities issued in exchange or
substitution therefor or on registration of transfer thereof, irrespective of
whether or not any notation in regard thereto is made upon any such Security.
Any action taken by the Holders of the percentage in aggregate principal amount
of the Securities of any or all series, as the case may be, specified in this
Indenture in connection with such action shall be conclusively binding upon the
Issuer, the Trustee and the Holders of all the Securities affected by such
action.

                                    ARTICLE 7
                             SUPPLEMENTAL INDENTURES

      Section 7.01. Supplemental Indentures Without Consent of Securityholders.
The Issuer, when authorized by a resolution of its Board (which resolutions may
provide general authorization for such action and may provide that the specific
terms of such action may be determined by officers of the Issuer authorized
thereby), and the Trustee may from time to time and at any time enter into an
indenture or indentures supplemental hereto for one or more of the following
purposes:

      (a) to convey, transfer, assign, mortgage or pledge to the Trustee as
security for the Securities of one or more series any property or assets;

      (b) to evidence the succession of another legal entity to the Issuer, or
successive successions, and the assumption by the successor legal entity of the
covenants, agreements and obligations of the Issuer pursuant to Article 8;

      (c) to add to the covenants of the Issuer such further covenants,
restrictions, conditions or provisions as the Issuer and the Trustee shall
consider to be for the protection of the Holders of Securities, and to make the
occurrence, or the occurrence and continuance, of a default in any such
additional covenants, restrictions, conditions or provisions an Event of Default
permitting the enforcement of all or any of the several remedies provided in
this Indenture as herein set forth; provided, that in respect of any such
additional covenant, restriction, condition or provision 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 an Event of Default or may
limit the remedies available to the Trustee upon such an Event of Default or may
limit the right of the Holders of

                                       37
<PAGE>

a majority in aggregate principal amount of the Securities of such series to
waive such an Event of Default;

      (d) to cure any ambiguity or to correct or supplement any provision
contained herein or in any supplemental indenture which may be defective or
inconsistent with any other provision contained herein or in any supplemental
indenture; or to make such other provisions in regard to matters or questions
arising under this Indenture or under any supplemental indenture as the Board
may deem necessary or desirable and which shall not adversely affect the
interests of the Holders of the Securities in any material respect;

      (e) to establish the form or terms of Securities of any series as
permitted by Sections 2.01 and 2.03; and

      (f) 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 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, pursuant to the requirements of Section 5.10.

      The Trustee is hereby authorized to join with the Issuer in the execution
of any such supplemental indenture, to make any further appropriate agreements
and stipulations which may be therein contained and to accept the conveyance,
transfer, assignment, mortgage or pledge of any property thereunder, but the
Trustee shall not be obligated to enter into any such supplemental indenture
which affects the Trustee's own rights, duties or immunities under this
Indenture or otherwise.

      Any supplemental indenture authorized by the provisions of this section
may be executed without the consent of the Holders of any of the Securities at
the time outstanding, notwithstanding any of the provisions of Section 7.02.

      Section 7.02. Supplemental Indentures With Consent of Securityholders.
With the consent (evidenced as provided in Article 6) of the Holders of not less
than a majority in aggregate principal amount of the Securities at the time
Outstanding of all series affected by such supplemental indenture (voting as one
class), the Issuer, when authorized by a resolution of its Board (which
resolutions may provide general authorization for such action and may provide
that the specific terms of such action may be determined by officers of the
Issuer authorized thereby), and the Trustee may, from time to time and at any
time, enter into an indenture or indentures supplemental hereto for the purpose
of adding any provisions to or changing in any manner or eliminating any of the
provisions of this Indenture or of any supplemental indenture or of modifying in
any manner the rights of the Holders of the Securities of each such series;
provided, that no such supplemental indenture shall (a) (i) extend the final
maturity of any Security,

                                       38
<PAGE>

(ii) reduce the principal amount thereof, (iii) reduce the rate or extend the
time of payment of interest thereon, (iv) reduce any amount payable on
redemption thereof, (v) make the principal thereof (including any amount in
respect of original issue discount), or interest thereon payable in any coin or
currency other than that provided in the Securities or in accordance with the
terms thereof, (vi) modify or amend any provisions for converting any currency
into any other currency as provided in the Securities or in accordance with the
terms thereof, (vii) reduce the amount of the principal of an Original Issue
Discount Security that would be due and payable upon an acceleration of the
maturity thereof pursuant to Section 4.01 or the amount thereof provable in
bankruptcy pursuant to Section 4.02, (viii) modify or amend any provisions
relating to the conversion or exchange of the Securities for securities of the
Issuer or a guarantor of the Securities or of other entities or other property
(or the cash value thereof), including the determination of the amount of
securities or other property (or cash) into which the Securities shall be
converted or exchanged, other than as provided in the antidilution provisions or
other similar adjustment provisions of the Securities or otherwise in accordance
with the terms thereof, (ix) alter the provisions of Section 10.11 or Section
10.13 or impair or affect the right of any Securityholder to institute suit for
the payment thereof or, if the Securities provide therefor, any right of
repayment at the option of the Securityholder, in each case without the consent
of the Holder of each Security so affected, or (b) reduce the aforesaid
percentage of Securities of any series, the consent of the Holders of which is
required for any such supplemental indenture, without the consent of the Holders
of each Security so affected.

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

      Upon the request of the Issuer, accompanied by a copy of a resolution of
the Board (which resolutions may provide general authorization for such action
and may provide that the specific terms of such action may be determined by
officers of the Issuer authorized thereby) certified by the secretary or an
assistant secretary of the Issuer authorizing the execution of any such
supplemental indenture, and upon the filing with the Trustee of evidence of the
consent of Securityholders as aforesaid and other documents, if any, required by
Section 6.01, the Trustee shall join with the Issuer in the execution of such
supplemental indenture unless such supplemental indenture affects the Trustee's
own rights, duties or immunities under this Indenture or otherwise, in which
case the Trustee may in its discretion, but shall not be obligated to, enter
into such supplemental indenture.

                                       39

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

      Promptly after the execution by the Issuer and the Trustee of any
supplemental indenture pursuant to the provisions of this Section, the Trustee
shall give notice thereof by (a) first class mail to the Holders of Securities
of each series affected thereby at their addresses as they shall appear on the
registry books of the Issuer or (b) by any other means set forth in such
supplemental indenture, setting forth in general terms the substance of such
supplemental indenture. Any failure of the Trustee to mail such notice, or any
defect therein, shall not, however, in any way impair or affect the validity of
any such supplemental indenture.

      Section 7.03. Effect of Supplemental Indenture. Upon the execution of any
supplemental indenture pursuant to the provisions hereof, this Indenture shall
be and be deemed to be modified and amended in accordance therewith and the
respective rights, limitations of rights, obligations, duties and immunities
under this Indenture of the Trustee, the Issuer and the Holders of Securities of
each series affected thereby shall thereafter be determined, exercised and
enforced hereunder subject in all respects to such modifications and amendments,
and all the terms and conditions of any such supplemental indenture shall be and
be deemed to be part of the terms and conditions of this Indenture for any and
all purposes.

      Section 7.04. Documents to Be Given to Trustee. The Trustee, subject to
the provisions of Sections 5.01 and 5.02, may receive an Officers' Certificate
and an Opinion of Counsel as conclusive evidence that any supplemental indenture
executed pursuant to this Article 7 complies with the applicable provisions of
this Indenture.

      Section 7.05. Notation On Securities In Respect Of Supplemental
Indentures. Securities of any series authenticated and delivered after the
execution of any supplemental indenture pursuant to the provisions of this
Article may bear a notation in form approved by the Trustee for such series as
to any matter provided for by such supplemental indenture or as to any action
taken by Securityholders. If the Issuer or the Trustee shall so determine, new
Securities of any series so modified as to conform, in the opinion of the
Trustee and the Board, to any modification of this Indenture contained in any
such supplemental indenture may be prepared by the Issuer, authenticated by the
Trustee and delivered in exchange for the Securities of such series then
Outstanding.

                    CONSOLIDATION, MERGER, SALE OR CONVEYANCE

      Section 8.01. Issuer May Consolidate, etc., on Certain Terms. The Issuer
covenants that it will not merge or consolidate with any other Person or sell or
convey all or substantially all of its assets to any Person, unless (i) either
the Issuer shall be the continuing legal entity, or the successor legal entity
or the Person which acquires by sale or conveyance substantially all the assets
of the Issuer (if other than the Issuer) shall expressly assume the due and
punctual payment of the principal of and interest on all the Securities,
according to their tenor, and the due and punctual performance and observance of
all of the covenants and conditions of this Indenture to be performed or
observed by the Issuer, by supplemental indenture satisfactory to the Trustee,
executed and delivered to the Trustee by such legal entity, and (ii) the Issuer
or such successor legal entity, as the case may be, shall not, immediately after
such merger or consolidation, or such sale or conveyance, be in default in the
performance of any such covenant or condition.

      Section 8.02. Successor Substituted. In case of any such consolidation,
merger, sale or conveyance, and following such an assumption by the successor
legal entity, such successor legal entity shall succeed to and be substituted
for the Issuer, with the same effect as if it had been named herein. Such
successor legal entity may cause to be signed, and may issue either in its own
name or in the name of the Issuer prior to such succession any or all of the
Securities issuable hereunder which theretofore shall not have been signed by
the Issuer and delivered to the Trustee; and, upon the order of such successor
legal entity instead of the Issuer 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 Issuer to the Trustee for authentication, and
any Securities which such successor legal entity thereafter shall cause to be
signed and delivered to the Trustee for that purpose. All of 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 phrasing and form (but not in substance) may be made in the
Securities thereafter to be issued as may be appropriate.

      In the event of any such sale or conveyance (other than a conveyance by
way of lease) the Issuer or any successor legal entity which shall theretofore
have become such in the manner described in this Article shall be discharged
from all obligations and covenants under this Indenture and the Securities and
may be liquidated and dissolved.

      Section 8.03. Opinion of Counsel to Trustee. The Trustee, subject to the
provisions of Sections 5.01 and 5.02, may receive an Opinion of Counsel,
prepared in accordance with Section 10.05, as conclusive evidence that any such
consolidation, merger, sale, lease or conveyance, and any such assumption, and
any such liquidation or dissolution, complies with the applicable provisions of
this Indenture.

            SATISFACTION AND DISCHARGE OF INDENTURE; UNCLAIMED MONEYS

      Section 9.01. Satisfaction and Discharge of Indenture. (a) If at any time
(i) the Issuer shall have paid or caused to be paid the principal of and
interest on all the Securities of any series outstanding hereunder (other than
Securities of such series which have been destroyed, lost or stolen and which
have been replaced or paid as provided in Section 2.09) as and when the same
shall have become due and payable, or (ii) the Issuer shall have delivered to
the Trustee for cancellation all Securities of any series theretofore
authenticated (other than any Securities of such series which shall have been
destroyed, lost or stolen and which shall have been replaced or paid as provided
in Section 2.09) or (iii) (A) all the securities of such series not theretofore
delivered to the Trustee for cancellation shall have become due and payable, or
are by their terms to become due and payable within one year or are to be called
for redemption within one year under arrangements satisfactory to the Trustee
for the giving of notice of redemption, and (B) the Issuer shall have
irrevocably deposited or caused to be deposited with the Trustee as trust funds
the entire amount in cash (other than moneys repaid by the Trustee or any paying
agent to the Issuer in accordance with Section 9.04) in the case of any series
of Securities the payments on which may only be made in United States dollars,
direct obligations of the United States of America, backed by its full faith and
credit ("U.S. Government Obligations"), maturing as to principal and interest at
such times and in such amounts as will insure the availability of cash, or a
combination thereof, sufficient to pay at maturity or upon redemption all
Securities of such series (other than any Securities of such series which shall
have been destroyed, lost or stolen and which shall have been replaced or paid
as provided in Section 2.09) not theretofore delivered to the Trustee for
cancellation, including principal and interest due or to become due on or prior
to such date of maturity as the case may be, and if, in any such case, the
Issuer shall also pay or cause to be paid all other sums payable hereunder by
the Issuer with respect to Securities of such series, then this Indenture shall
cease to be of further effect with respect to Securities of such series (except
as to (i) rights of registration of transfer and exchange of securities of such
series, and the Issuer's right of optional redemption, if any, (ii) substitution
of mutilated, defaced, destroyed, lost or stolen Securities, (iii) rights of
holders to receive payments of principal thereof and interest thereon upon the
original stated due

                                       42
<PAGE>

date therefor (but no upon acceleration), and remaining rights of the holders to
receive mandatory sinking fund payments, if any, (iv) the rights, obligations
and immunities of the Trustee hereunder and (v) the rights of the
Securityholders of such series as beneficiaries hereof with respect to the
property so deposited with the Trustee payable to all or any of them), and the
Trustee, on demand of the Issuer accompanied by an Officers' Certificate and an
Opinion of Counsel and at the cost and expense of the Issuer, shall execute
proper instruments acknowledging such satisfaction of and discharging this
Indenture with respect to such series; provided, that the rights of Holders of
the Securities to receive amounts in respect of principal of and interest on the
Securities held by them shall not be delayed longer than required by
then-applicable mandatory rules or policies of any securities exchange upon
which the Securities are listed. The Issuer agrees to reimburse the Trustee for
any costs or expenses thereafter reasonably and properly incurred and to
compensate the Trustee for any services thereafter reasonably and properly
rendered by the Trustee in connection with this Indenture or the Securities of
such series.

      (b) The following provisions shall apply to the Securities of each series
unless specifically otherwise provided in a Board Resolution, Officers'
Certificate or indenture supplemental hereto provided pursuant to Section 2.03.
In addition to discharge of the Indenture pursuant to the next preceding
paragraph, in the case of any series of Securities the exact amounts (including
the currency of payment) of principal of and interest due on which can be
determined at the time of making the deposit referred to in clause 9.01(b)(i)
below, the Issuer shall be deemed to have paid and discharged the entire
indebtedness on all the Securities of such a series on the 91st day after the
date of the deposit referred to in clause 9.01(b)(i) below, and the provisions
of this Indenture with respect to the Securities of such series thereto shall no
longer be in effect (except as to (1) rights of registration of transfer and
exchange of Securities of such series and the Issuer's right of optional
redemption, if any, (2) substitution of mutilated, defaced, destroyed, lost or
stolen Securities, (3) rights of Holders of Securities to receive payments of
principal thereof and interest thereon, upon the original stated due dates
therefor (but not upon acceleration), and remaining rights of the Holders to
receive mandatory sinking fund payments, if any, (4) the rights, obligations,
duties and immunities of the Trustee hereunder, (5) the rights of the Holders of
Securities of such series as beneficiaries hereof with respect to the property
so deposited with the Trustee payable to all or any of them and (6) the
obligations of the Issuer under Section 3.02) and the Trustee, at the expense of
the Issuer and any guarantor of the Securities, shall at the Issuer's or such
guarantor's request, execute proper instruments acknowledging the same, if

            (i) with reference to this provision the Issuer or such guarantor
      has irrevocably deposited or caused to be irrevocably deposited with the
      Trustee as trust funds in trust, specifically pledged as security for, and
      dedicated solely to, the benefit of the Holders of the Securities of such

                                       43
<PAGE>

      series (A) cash in an amount, or (B) in the case of any series of
      Securities the payments on which may only be made in Dollars, U.S.
      Government Obligations, maturing as to principal and interest at such
      times and in such amounts as will insure the availability of cash or (C) a
      combination thereof, sufficient, in the opinion of a nationally recognized
      firm of independent public accountants expressed in a written
      certification thereof delivered to the Trustee, to pay (1) the principal
      and interest on all Securities of such series and Coupons appertaining
      thereto on each date that such principal or interest is due and payable
      and (2) any mandatory sinking fund payments on the dates on which such
      payments are due and payable in accordance with the terms of the Indenture
      and the Securities of such series;

            (ii) such deposit will not result in a breach or violation of, or
      constitute a default under, any agreement or instrument to which the
      Issuer is a party or by which it is bound;

            (iii) the Issuer or such guarantor has delivered to the Trustee an
      Opinion of Counsel based on the fact that (x) the Issuer has received
      from, or there has been published by, the Internal Revenue Service a
      ruling or (y) since the date hereof, there has been a change in the
      applicable Federal income tax law, in either case to the effect that, and
      such opinion shall confirm that, the Holders of the Securities of such
      series and Coupons appertaining thereto will not recognize income, gain or
      loss for Federal income tax purposes as a result of such deposit,
      defeasance and discharge and will be subject to Federal income tax on the
      same amount and in the same manner and at the same times, as would have
      been the case if such deposit, defeasance and discharge had not occurred;
      and

            (iv) the Issuer or such guarantor has delivered to the Trustee an
      Officers' Certificate or guarantor's Officers' Certificate and an Opinion
      of Counsel, each stating that all conditions precedent provided for
      relating to the defeasance contemplated by this provision have been
      complied with.

      (c) Each of the Issuer and any guarantor of the Securities shall be
released from its obligations under Section 8.01 with respect to the Securities
of any Series, Outstanding, and under any guarantee in respect thereof, on and
after the date the conditions set forth below are satisfied (hereinafter,
"covenant defeasance"). For this purpose, such covenant defeasance means that,
with respect to the Outstanding Securities of any Series, and under a guarantee
in respect thereof, the Issuer and any guarantor of the Securities may omit to
comply with and shall have no liability in respect of any term, condition or
limitation set forth in such Sections, whether directly or indirectly by reason
of any reference elsewhere herein to such Sections or by reason of any reference
in such Sections to any other provision herein or in any other document and such
omission to

                                       44
<PAGE>

comply shall not constitute an Event of Default under Section 4.01, but the
remainder of this Indenture and such Securities and Coupons and the Guarantee
shall be unaffected thereby. The following shall be the conditions to
application of this subsection (c) of this Section 9.01:

            (i) The Issuer or such guarantor has irrevocably deposited or caused
      to be deposited with the Trustee 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 the Securities of
      such series, (A) cash in an amount, or (B) in the case of any series of
      Securities the payments on which may only be made in Dollars, U.S.
      Government Obligations maturing as to principal and interest at such times
      and in such amounts as will insure the availability of cash or (C) a
      combination thereof, sufficient, in the opinion of a nationally recognized
      firm of independent public accountants expressed in a written
      certification thereof delivered to the Trustee, to pay (1) the principal
      and interest on all Securities of such series and Coupons appertaining
      thereto and (2) any mandatory sinking fund payments on the day on which
      such payments are due and payable in accordance with the terms of the
      Indenture and the Securities of such series.

            (ii) No Event of Default or event which with notice or lapse of time
      or both would become an Event of Default with respect to the Securities
      shall have occurred and be continuing on the date of such deposit or,
      insofar as subsections 4.01(c) and 4.01(d) 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).

            (iii) Such covenant defeasance shall not cause the Trustee to have a
      conflicting interest for purposes of the Trust Indenture Act of 1939 with
      respect to any securities of the Issuer.

            (iv) Such covenant defeasance shall not result in a breach or
      violation of, or constitute a default under, this Indenture or any other
      agreement or instrument to which the Issuer or such guarantor is a party
      or by which either of them is bound.

            (v) Such covenant defeasance shall not cause any Securities then
      listed on any registered national securities exchange under the Securities
      Exchange Act of 1934, as amended, to be delisted.

            (vi) The Issuer or such guarantor shall have delivered to the
      Trustee an Officers' Certificate or guarantor's Officers' Certificate, as
      the case may be, and Opinion of Counsel to the effect that the Holders of
      the

                                       45
<PAGE>

      Securities of such series 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.

            (vii) The Issuer or such guarantor shall have delivered to the
      Trustee an Officers' Certificate or guarantor's Officers' Certificate, as
      the case may be, and an Opinion of Counsel, each stating that all
      conditions precedent provided for relating to the covenant defeasance
      contemplated by this provision have been complied with.

      Section 9.02. Application by Trustee of Funds Deposited for Payment of
Securities. Subject to Section 9.04 and any subordination provisions applicable
to the Securities, all moneys deposited with the Trustee pursuant to Section
9.01 shall be held in trust and applied by it to the payment, either directly or
through any paying agent (including the Issuer acting as its own paying agent),
to the Holders of the particular Securities of such series for the payment or
redemption of which such moneys have been deposited with the Trustee, of all
sums due and to become due thereon for principal and interest; but such money
need not be segregated from other funds except to the extent required by law.

      Section 9.03. Repayment of Moneys Held by Paying Agent. In connection with
the satisfaction and discharge of this Indenture with respect to Securities of
any series, all moneys then held by any paying agent under the provisions of
this Indenture with respect to such series of Securities shall, upon demand of
the Issuer, be repaid to it or paid to the Trustee and thereupon such paying
agent shall be released from all further liability with respect to such moneys.

      Section 9.04. Return of Moneys Held by Trustee and Paying Agent Unclaimed
for Two Years. Any moneys deposited with or paid to the Trustee or any paying
agent for the payment of the principal of or interest on any Security of any
series and not applied but remaining unclaimed for two years after the date upon
which such principal or interest shall have become due and payable, shall, upon
the written request of the Issuer and unless otherwise required by mandatory
provisions of applicable escheat or abandoned or unclaimed property law, be
repaid to the Issuer by the Trustee for such series or such paying agent, and
the Holder of the Security of such series shall, unless otherwise required by
mandatory provisions of applicable escheat or abandoned or unclaimed property
laws, thereafter look only to the Issuer for any payment which such Holder may
be entitled to collect, and all liability of the Trustee or any paying agent
with respect to such moneys shall thereupon cease.

                            MISCELLANEOUS PROVISIONS

      Section 10.01. Incorporators, Stockholders, Members, Officers and
Directors of Issuer Exempt from Individual Liability. No recourse under or upon
any obligation, covenant or agreement contained in this Indenture, or in any
Security, or because of any indebtedness evidenced thereby, shall be had against
any incorporator, as such or against any past, present or future stockholder,
member, officer or director, as such, of the Issuer or of any successor, either
directly or through the Issuer 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 10.02. Provisions of Indenture for the Sole Benefit of Parties and
Securityholders. Nothing in this Indenture or in the Securities, expressed or
implied, shall give or be construed to give to any person, firm or corporation,
other than the parties hereto and their successors and the Holders of the
Securities, any legal or equitable right, remedy or claim under this Indenture
or under any covenant or provision herein contained, all such covenants and
provisions being for the sole benefit of the parties hereto and their successors
and of the Holders of the Securities.

      Section 10.03. Successors and Assigns of Issuer Bound by Indenture. All
the covenants, stipulations, promises and agreements in this Indenture contained
by or in behalf of the Issuer shall bind its successors and assigns, whether so
expressed or not.

      Section 10.04. Notices and Demands on Issuer, Trustee and Securityholders.
Any notice or demand which by any provision of this Indenture is required or
permitted to be given or served by the Trustee or by the Holders of Securities
to or on the Issuer may be given or served by being deposited postage prepaid,
first-class mail (except as otherwise specifically provided herein) addressed
(until another address of the Issuer is filed by the Issuer with the Trustee) to
ABN AMRO Holding N.V. at the following address:

      ABN AMRO Holding N.V.

      Any notice, direction, request or demand by the Issuer or any
Securityholder to or upon the Trustee shall be deemed to have been sufficiently
given or made, for all purposes, if given or made to its Corporate Trust Office
at [__].

      Where this Indenture provides for notice to Holders, such notice shall be
sufficiently given (unless otherwise herein expressly provided) if in writing
and mailed, first-class postage prepaid, to each Holder entitled thereto, at his
last address as it appears in the Security register. In any case where notice to
Holders is given by mail, neither the failure to mail such notice, nor any
defect in any notice so mailed, to any particular Holder shall affect the
sufficiency of such notice with respect to other Holders. Where this Indenture
provides for notice in any manner, such notice may be waived in writing by the
person entitled to receive such notice, either before or after the event, and
such waiver shall be the equivalent of such notice. Waivers of notice by Holders
shall be filed with the Trustee, but such filing shall not be a condition
precedent to the validity of any action taken in reliance upon such waiver.

      In case, by reason of the suspension of or irregularities in regular mail
service, it shall be impracticable to mail notice to the Issuer and
Securityholders when such notice is required to be given pursuant to any
provision of this Indenture, then any manner of giving such notice as shall be
satisfactory to the Trustee shall be deemed to be a sufficient giving of such
notice.

      Section 10.05. Officers' Certificates and Opinions of Counsel; Statements
to be Contained Therein. Upon any application or demand by the Issuer to the
Trustee to take any action under any of the provisions of this Indenture, the
Issuer shall furnish to the Trustee an Officers' Certificate stating that all
conditions precedent provided for in this Indenture relating to the proposed
action have been complied with and an Opinion of Counsel stating that in the
opinion of such counsel all such conditions precedent have been complied with,
except that in the case of any such application or demand as to which the
furnishing of such documents is specifically required by any provision of this
Indenture relating to such particular application or demand, no additional
certificate or opinion need be furnished.

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

                                       48
<PAGE>

statement as to whether or not, in the opinion of such person, such condition or
covenant has been complied with.

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

      Any certificate, statement or opinion of an officer of the Issuer or of
counsel may be based, insofar as it relates to accounting matters, upon a
certificate or opinion of or representations by an accountant or firm of
accountants in the employ of the Issuer, unless such officer or counsel, as the
case may be, knows that the certificate or opinion or representations with
respect to the accounting matters upon which his certificate, statement or
opinion may be based as aforesaid are erroneous, or in the exercise of
reasonable care should know that the same are erroneous.

      Any certificate or opinion of any independent firm of public accountants
filed with the Trustee shall contain a statement that such firm is independent.

      Section 10.06. Payments Due on Saturdays, Sundays and Holidays. If the
date of maturity of interest on or principal of the Securities of any series or
the date fixed for redemption or repayment of any such Security shall not be a
Business Day, then payment of interest or principal need not be made on such
date, but may be made on the next succeeding Business Day with the same force
and effect as if made on the date of maturity or the date fixed for redemption,
and no interest shall accrue for the period after such date.

      Section 10.07. Conflict of any Provision of Indenture with Trust Indenture
Act of 1939. If and to the extent that any provision of this Indenture limits,
qualifies or conflicts with another provision included in this Indenture by
operation of Sections 310 to 317, inclusive, of the Trust Indenture Act of 1939
(an "incorporated provision"), such incorporated provision shall control.

      Section 10.08. New York Law to Govern. This Indenture and each Security
shall be deemed to be a contract under the laws of the State of New

                                       49
<PAGE>

York, and for all purposes shall be construed in accordance with the laws of
such State, except as may otherwise be required by mandatory provisions of law.

      Section 10.09. Counterparts. This Indenture may be executed in any number
of counterparts, each of which shall be an original; but such counterparts shall
together constitute but one and the same instrument.

      Section 10.10. Effect of Headings. The Article and Section headings herein
and the Table of Contents are for convenience only and shall not affect the
construction hereof.

      Section 10.11. Securities in a Non-U.S. Currency. Unless otherwise
specified in an Officers' Certificate delivered pursuant to Section 2.03 of this
Indenture with respect to a particular series of Securities, whenever for
purposes of this Indenture any action may be taken by the Holders of a specified
percentage in aggregate principal amount of Securities of all series or all
series affected by a particular action at the time Outstanding and, at such
time, there are Outstanding Securities of any series which are denominated in a
coin or currency other than Dollars, then the principal amount of Securities of
such series which shall be deemed to be Outstanding for the purpose of taking
such action shall be that amount of Dollars that could be obtained for such
amount at the Market Exchange Rate. For purposes of this Section 10.11, Market
Exchange Rate shall mean the noon Dollar buying rate in New York City for cable
transfers of that currency as published by the Federal Reserve Bank of New York.
If such Market Exchange Rate is not available for any reason with respect to
such currency, the Trustee shall use, in its sole discretion and without
liability on its part, such quotation of the Federal Reserve Bank of New York as
of the most recent available date, or quotations from one or more major banks in
The City of New York or in the country of issue of the currency in question, or
such other quotations as the Trustee shall deem appropriate. The provisions of
this paragraph shall apply in determining the equivalent principal amount in
respect of Securities of a series denominated in a currency other than Dollars
in connection with any action taken by Holders of Securities pursuant to the
terms of this Indenture.

      All decisions and determinations of the Trustee regarding the Market
Exchange Rate or any alternative determination provided for in the preceding
paragraph shall be in its sole discretion and shall, in the absence of manifest
error, be conclusive to the extent permitted by law for all purposes and
irrevocably binding upon the Issuer and all Holders.

      Section 10.12. Submission to Jurisdiction. The Issuer agrees that any
legal suit, action or proceeding arising out of or based upon this Indenture may
be instituted in any State or Federal court in the Borough of Manhattan, City
and State of New York, and, to the fullest extent permitted by law, waives any
objection which it may now or hereafter have to the laying of venue of any such

                                       50
<PAGE>

proceeding, and irrevocably submits to the jurisdiction of such court in any
suit, action or proceeding. The Issuer has appointed [Willie J. Miller, Jr.,
Esq., Chief Legal Officer and Executive Vice President], ABN AMRO North America,
Inc., as its authorized agent (the "Authorized Agent") upon which process may be
instituted in any State or Federal court in the Borough of Manhattan, City and
State of New York and the Issuer expressly accepts the jurisdiction of any such
court in respect of such action. Such appointment shall be irrevocable unless
and until a successor authorized agent, located or with an office in the Borough
of Manhattan, City and State of New York, shall have been appointed by the
Issuer and such appointment shall have been accepted by such successor
authorized agent. The Issuer represents and warrants that the Authorized Agent
has agreed to act as said agent for service of process, and the Issuer agrees to
take any and all action, including the filing of any and all documents and
instruments, that may be necessary to continue such appointment in full force
and effect as aforesaid. Service of process upon the Authorized Agent and
written notice of such service to the Issuer shall be deemed, in every respect,
effective service of process upon the Issuer.

      Section 10.13. Judgment Currency. The Issuer agrees, to the fullest extent
that it may effectively do so under applicable law, that (a) if for the purpose
of obtaining judgment in any court it is necessary to convert the sum due in
respect of the principal of or interest on the Securities of any series (the
"Required Currency") into a currency in which a judgment will be rendered (the
"Judgment Currency"), the rate of exchange used shall be the rate at which in
accordance with normal banking procedures the Trustee could purchase in The City
of New York the Required Currency with the Judgment Currency on the day on which
final unappealable judgment is entered, unless such day is not a New York
Banking Day, then, to the extent permitted by applicable law, the rate of
exchange used shall be the rate at which in accordance with normal banking
procedures the Trustee could purchase in The City of New York the Required
Currency with the Judgment Currency on the New York Banking Day preceding the
day on which final unappealable judgment is entered and (b) its obligations
under this Indenture to make payments in the Required Currency (i) shall not be
discharged or satisfied by any tender, or any recovery pursuant to any judgment
(whether or not entered in accordance with subsection (a)), in any currency
other than the Required Currency, except to the extent that such tender or
recovery shall result in the actual receipt, by the payee, of the full amount of
the Required Currency expressed to be payable in respect of such payments, (ii)
shall be enforceable as an alternative or additional cause of action for the
purpose of recovering in the Required Currency the amount, if any, by which such
actual receipt shall fall short of the full amount of the Required Currency so
expressed to be payable and (iii) shall not be affected by judgment being
obtained for any other sum due under this Indenture. For purposes of the
foregoing, "New York Banking Day" means any day except a Saturday, Sunday or a
legal holiday in

                                       51
<PAGE>

The City of New York or a day on which banking institutions in The City of New
York are authorized or required by law or executive order to close.

                                   ARTICLE 11
                   REDEMPTION OF SECURITIES AND SINKING FUNDS

      Section 11.01. Applicability Of Article. The provisions of this Article
shall be applicable to the Securities of any series which are redeemable before
their maturity or to any sinking fund for the retirement of Securities of a
series except as otherwise specified as contemplated by Section 2.03 for
Securities of such series.

      Section 11.02. Notice Of Redemption; Partial Redemptions. Notice of
redemption to the Holders of Securities of any series to be redeemed as a whole
or in part at the option of the Issuer shall be given by mailing notice of such
redemption by first class mail, postage prepaid, at least 30 days and not more
than 60 days prior to the date fixed for redemption to such Holders of
Securities of such series at their last addresses as they shall appear upon the
registry books. Any notice which is mailed in the manner herein provided shall
be conclusively presumed to have been duly given, whether or not the Holder
receives the notice. Failure to give notice by mail, or any defect in the notice
to the Holder of any Security of a series designated for redemption as a whole
or in part shall not affect the validity of the proceedings for the redemption
of any other Security of such series.

      The notice of redemption to each such Holder shall specify the principal
amount of each Security of such series held by such Holder to be redeemed, the
date fixed for redemption, the redemption price, the place or places of payment,
that payment will be made upon presentation and surrender of such Securities,
that such redemption is pursuant to the mandatory or optional sinking fund, or
both, if such be the case, that interest accrued to the date fixed for
redemption will be paid as specified in such notice and that on and after said
date interest thereon or on the portions thereof to be redeemed will cease to
accrue. In case any Security of a series is to be redeemed in part only the
notice of redemption shall state the portion of the principal amount thereof to
be redeemed and shall state that on and after the date fixed for redemption,
upon surrender of such Security, a new Security or Securities of such series in
principal amount equal to the unredeemed portion thereof will be issued.

      The notice of redemption of Securities of any series to be redeemed at the
option of the Issuer shall be given by the Issuer or, at the Issuer's request,
by the Trustee in the name and at the expense of the Issuer.

                                       52
<PAGE>

      On or before the redemption date specified in the notice of redemption
given as provided in this Section, the Issuer will deposit with the Trustee or
with one or more paying agents (or, if the Issuer is acting as its own paying
agent, set aside, segregate and hold in trust as provided in Section 3.04) an
amount of money or other property sufficient to redeem on the redemption date
all the Securities of such series so called for redemption at the appropriate
redemption price, together with accrued interest to the date fixed for
redemption. If less than all the outstanding Securities of a series are to be
redeemed, the Issuer will deliver to the Trustee at least 70 days prior to the
date fixed for redemption an Officers' Certificate stating the aggregate
principal amount of Securities to be redeemed.

      If less than all the Securities of a series are to be redeemed, the
Trustee shall select, in such manner as it shall deem appropriate and fair,
Securities of such Series to be redeemed in whole or in part. Securities may be
redeemed in part in multiples equal to the minimum authorized denomination for
Securities of such series or any multiple thereof. The Trustee shall promptly
notify the Issuer in writing of the Securities of such series selected for
redemption and, in the case of any Securities of such series 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 of any series 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 11.03. Payment of Securities Called for Redemption. If notice of
redemption has been given as above provided, the Securities or portions of
Securities specified in such notice shall become due and payable on the date and
at the place stated in such notice at the applicable redemption price, together
with interest accrued to the date fixed for redemption, and on and after said
date (unless the Issuer shall default in the payment of such Securities at the
redemption price, together with interest accrued to said date) interest on the
Securities or portions of Securities so called for redemption shall cease to
accrue and, except as provided in Sections 5.05 and 9.04, such Securities shall
cease from and after the date fixed for redemption to be entitled to any benefit
or security under this Indenture, and the Holders thereof shall have no right in
respect of such Securities except the right to receive the redemption price
thereof and unpaid interest to the date fixed for redemption. On presentation
and surrender of such Securities at a place of payment specified in said notice,
said Securities or the specified portions thereof shall be paid and redeemed by
the Issuer at the applicable redemption price, together with interest accrued
thereon to the date fixed for redemption; provided that any semiannual payment
of interest becoming due on the date fixed for redemption shall be payable to
the Holders of such Securities registered as such on the relevant record date
subject to the terms and provisions of Sections 2.03 and 2.04 hereof.

                                       53
<PAGE>

      If any Security called for redemption shall not be so paid upon surrender
thereof for redemption, the principal shall, until paid or duly provided for,
bear interest from the date fixed for redemption at the rate of interest or
Yield to Maturity (in the case of an Original Issue Discount Security) borne by
such Security.

      Upon presentation of any Security redeemed in part only, the Issuer shall
execute and the Trustee shall authenticate and deliver to or on the order of the
Holder thereof, at the expense of the Issuer, a new Security or Securities of
such series, of authorized denominations, in principal amount equal to the
unredeemed portion of the Security so presented.

      Section 11.04. Exclusion of Certain Securities from Eligibility for
Selection for Redemption. Securities shall be excluded from eligibility for
selection for redemption if they are identified by registration and certificate
number in a written statement signed by an authorized officer of the Issuer and
delivered to the Trustee at least 40 days prior to the last date on which notice
of redemption may be given as being owned of record and beneficially by, and not
pledged or hypothecated by either (a) the Issuer or (b) an entity specifically
identified in such written statement as directly or indirectly controlling or
controlled by or under direct or indirect common control with the Issuer.

      Section 11.05. Mandatory and Optional Sinking Funds. The minimum amount of
any sinking fund payment provided for by the terms of the 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 Securities
of any series is herein referred to as an "optional sinking fund payment". The
date on which a sinking fund payment is to be made is herein referred to as the
"sinking fund payment date".

      In lieu of making all or any part of any mandatory sinking fund payment
with respect to any series of Securities in cash, the Issuer may at its option
(a) deliver to the Trustee Securities of such series theretofore purchased or
otherwise acquired (except upon redemption pursuant to the mandatory sinking
fund) by the Issuer or receive credit for Securities of such series (not
previously so credited) theretofore purchased or otherwise acquired (except as
aforesaid) by the Issuer and delivered to the Trustee for cancellation pursuant
to Section 2.07, (b) receive credit for optional sinking fund payments (not
previously so credited) made pursuant to this Section, or (c) receive credit for
Securities of such series (not previously so credited) redeemed by the Issuer
through any optional redemption provision contained in the terms of such series.
Securities so delivered or credited shall be received or credited by the Trustee
at the sinking fund redemption price specified in such Securities.

                                       54
<PAGE>

      On or before the sixtieth day next preceding each sinking fund payment
date for any series, the Issuer will deliver to the Trustee a written statement
(which need not contain the statements required by Section 10.05) signed by an
authorized officer of the Issuer (a) specifying the portion of the mandatory
sinking fund payment to be satisfied by payment of cash and the portion to be
satisfied by credit of Securities of such series, (b) stating that none of the
Securities of such series has theretofore been so credited, (c) stating that no
defaults in the payment of interest or Events of Default with respect to such
series have occurred (which have not been waived or cured) and are continuing
and (d) stating whether or not the Issuer intends to exercise its right to make
an optional sinking fund payment with respect to such series and, if so,
specifying the amount of such optional sinking fund payment which the Issuer
intends to pay on or before the next succeeding sinking fund payment date. Any
Securities of such series to be credited and required to be delivered to the
Trustee in order for the Issuer to be entitled to credit therefor as aforesaid
which have not theretofore been delivered to the Trustee shall be delivered for
cancellation pursuant to Section 2.10 to the Trustee with such written statement
(or reasonably promptly thereafter if acceptable to the Trustee). Such written
statement shall be irrevocable and upon its receipt by the Trustee the Issuer
shall become unconditionally obligated to make all the cash payments or payments
therein referred to, if any, on or before the next succeeding sinking fund
payment date. Failure of the Issuer, on or before any such sixtieth day, to
deliver such written statement and Securities specified in this paragraph, if
any, shall not constitute a default but shall constitute, on and as of such
date, the irrevocable election of the Issuer (i) that the mandatory sinking fund
payment for such series due on the next succeeding sinking fund payment date
shall be paid entirely in cash without the option to deliver or credit
Securities of such series in respect thereof and (ii) that the Issuer will make
no optional sinking fund payment with respect to such series as provided in this
Section.

      If the sinking fund payment or payments (mandatory or optional or both) to
be made in cash on the next succeeding sinking fund payment date plus any unused
balance of any preceding sinking fund payments made in cash shall exceed $50,000
(or a lesser sum if the Issuer shall so request) with respect to the Securities
of any particular series, such cash shall be applied on the next succeeding
sinking fund payment date to the redemption of Securities of such series at the
sinking fund redemption price together with accrued interest to the date fixed
for redemption. If such amount shall be $50,000 or less and the Issuer makes no
such request then it shall be carried over until a sum in excess of $50,000 is
available. The Trustee shall select, in the manner provided in Section 11.02,
for redemption on such sinking fund payment date a sufficient principal amount
of Securities of such series to absorb said cash, as nearly as may be, and shall
(if requested in writing by the Issuer) inform the Issuer of the serial numbers
of the Securities of such series (or portions thereof) so selected. Securities
of any series which are (a) owned by the Issuer or an entity known by the
Trustee to be

                                       55
<PAGE>

directly or indirectly controlling or controlled by or under direct or indirect
common control with the Issuer, as shown by the Security register, and not known
to the Trustee to have been pledged or hypothecated by the Issuer or any such
entity or (b) identified in an Officers' Certificate at least 60 days prior to
the sinking fund payment date as being beneficially owned by, and not pledged or
hypothecated by, the Issuer or an entity directly or indirectly controlling or
controlled by or under direct or indirect common control with the Issuer shall
be excluded from Securities of such series eligible for selection for
redemption. The Trustee, in the name and at the expense of the Issuer (or the
Issuer, if it shall so request the Trustee in writing) shall cause notice of
redemption of the Securities of such series to be given in substantially the
manner provided in Section 11.02 (and with the effect provided in Section 11.03)
for the redemption of Securities of such series in part at the option of the
Issuer. The amount of any sinking fund payments not so applied or allocated to
the redemption of Securities of such series shall be added to the next cash
sinking fund payment for such series and, together with such payment, shall be
applied in accordance with the provisions of this Section. Any and all sinking
fund moneys held on the stated maturity date of the Securities of any particular
series (or earlier, if such maturity is accelerated), which are not held for the
payment or redemption of particular Securities of such series shall be applied,
together with other moneys, if necessary, sufficient for the purpose, to the
payment of the principal of, and interest on, the Securities of such series at
maturity.

      On or before each sinking fund payment date, the Issuer shall pay to the
Trustee in cash or shall otherwise provide for the payment of all interest
accrued to the date fixed for redemption on Securities to be redeemed on the
next following sinking fund payment date.

      The Trustee shall not redeem or cause to be redeemed any Securities of a
series with sinking fund moneys or give any notice of redemption of Securities
for such series by operation of the sinking fund during the continuance of a
default in payment of interest on such Securities or of any Event of Default
except that, where the mailing of notice of redemption of any Securities shall
theretofore have been made, the Trustee shall redeem or cause to be redeemed
such Securities, provided that it shall have received from the Issuer a sum
sufficient for such redemption. Except as aforesaid, any moneys in the sinking
fund for such series at the time when any such default or Event of Default shall
occur, and any moneys thereafter paid into the sinking fund, shall, during the
continuance of such default or Event of Default, be deemed to have been
collected under Article 4 and held for the payment of all such Securities. In
case such Event of Default shall have been waived as provided in Section 4.09 or
the default cured on or before the sixtieth day preceding the sinking fund
payment date in any year, such moneys shall thereafter be applied on the next
succeeding sinking fund payment date in accordance with this Section to the
redemption of such Securities.

            (iii) that all laws and requirements in respect of the execution and
      delivery by the Issuer of the Securities have been complied with; and

            (iv) covering such other matters as the Trustee may reasonably
      request.

      The Trustee shall have the right to decline to authenticate and deliver
any Securities under this Section if the Trustee, being advised by counsel,
determines that such action may not lawfully be taken by the Issuer or if the
Trustee in good faith by its board of directors or board of trustees, executive
committee, or a trust committee of directors or trustees or Responsible Officers
shall determine that such action would expose the Trustee to personal liability
to existing Holders.

      Section 2.05. Execution of Securities. The Securities shall be signed on
behalf of the Issuer by any two officers of the Issuer authorized by the Board
to execute such Securities, which Securities may, but need not, be attested.
Such signatures may be the manual or facsimile signatures of the present or any
future such officers. Typographical and other minor errors or defects in any
such reproduction of the seal or any such signature shall not affect the
validity or enforceability of any Security that has been duly authenticated and
delivered by the Trustee.

      In case any officer of the Issuer who shall have signed any of the
Securities shall cease to be such officer before the Security so signed shall be
authenticated and delivered by the Trustee or disposed of by the Issuer, such
Security nevertheless may be authenticated and delivered or disposed of as
though

                                       10
<PAGE>

the person who signed such Security had not ceased to be such officer of the
Issuer; and any Security may be signed on behalf of the Issuer by such persons
as, at the actual date of the execution of such Security, shall be the proper
officers of the Issuer, although at the date of the execution and delivery of
this Indenture any such person was not such an officer.

      Section 2.06. Certificate of Authorization. Only such Securities as shall
bear thereon a certificate of authentication substantially in the form
hereinbefore recited, executed by the Trustee by the manual signature of one of
its authorized officers, shall be entitled to the benefits of this Indenture or
be valid or obligatory for any purpose. Such certificate by the Trustee upon any
Security executed by the Issuer shall be conclusive evidence that the Security
so authenticated has been duly authenticated and delivered hereunder and that
the holder is entitled to the benefits of this Indenture.

      Section 2.07. Denomination and Date of Securities; Payments of Interest.
The Securities shall be issuable as registered securities without coupons and in
denominations as shall be specified as contemplated by Section 2.03. In the
absence of any such specification with respect to the Securities of any series,
the Securities of such series shall be issuable in denominations of $1,000 and
any multiple thereof. The Securities shall be numbered, lettered, or otherwise
distinguished in such manner or in accordance with such plan as the officers of
the Issuer executing the same may determine with the approval of the Trustee as
evidenced by the execution and authentication thereof.

      Each Security shall be dated the date of its authentication, shall bear
interest, if any, from the date and shall be payable on the dates, in each case,
which shall be specified as contemplated by Section 2.03.

      The person in whose name any Security of any series is registered at the
close of business on any record date applicable to a particular series with
respect to any interest payment date for such series shall be entitled to
receive the interest, if any, payable on such interest payment date
notwithstanding any transfer or exchange of such Security subsequent to the
record date and prior to such interest payment date, except if and to the extent
the Issuer shall default in the payment of the interest due on such interest
payment date for such series, in which case such defaulted interest shall be
paid to the persons in whose names Outstanding Securities for such series are
registered at the close of business on a subsequent record date (which shall be
not less than five Business Days prior to the date of payment of such defaulted
interest) established by notice given by mail by or on behalf of the Issuer to
the holders of Securities not less than 15 days preceding such subsequent record
date. The term "record date" as used with respect to any interest payment date
(except a date for payment of defaulted interest) shall mean the date specified
as such in the terms of the Securities of any particular series, or, if no such
date is so specified, if such interest payment date is the first day of a

                                       11
<PAGE>

calendar month, the fifteenth day of the next preceding calendar month or, if
such interest payment date is the fifteenth day of a calendar month, the first
day of such calendar month, whether or not such record date is a Business Day.

      Section 2.08. Regulation, Transfer and Exchange. The Issuer will keep or
cause to be kept at each office or agency to be maintained for the purpose as
provided in Section 3.02 a register or registers in which, subject to such
reasonable regulations as it may prescribe, it will register, and will register
the transfer of, Securities as in this Article provided. Such register shall be
in written form in the English language or in any other form capable of being
converted into such form within a reasonable time. At all reasonable times such
register or registers shall be open for inspection by the Trustee.

      Upon due presentation for registration of transfer of any Security of any
series at any such office or agency to be maintained for the purpose as provided
in Section 3.02, the Issuer shall execute and the Trustee shall authenticate and
deliver in the name of the transferee or transferees a new Security or
Securities of the same series in authorized denominations for a like aggregate
principal amount.

      Any Security or Securities of any series may be exchanged for a Security
or Securities of the same series in other authorized denominations, in an equal
aggregate principal amount. Securities of any series to be exchanged shall be
surrendered at any office or agency to be maintained by the Issuer for the
purpose as provided in Section 3.02, and the Issuer shall execute and the
Trustee shall authenticate and deliver in exchange therefor the Security or
Securities of the same series which the Securityholder making the exchange shall
be entitled to receive, bearing numbers not contemporaneously outstanding.

      All Securities presented for registration of transfer, exchange,
redemption or payment shall (if so required by the Issuer or the Trustee) be
duly endorsed by, or be accompanied by a written instrument or instruments of
transfer in form satisfactory to the Issuer and the Trustee duly executed by,
the holder or his attorney duly authorized in writing.

      The Issuer may require payment of a sum sufficient to cover any tax or
other governmental charge that may be imposed in connection with any exchange or
registration of transfer of Securities. No service charge shall be made for any
such transaction.

      The Issuer shall not be required to exchange or register a transfer of (a)
any Securities of any series for a period of 15 days next preceding the first
mailing of notice of redemption of Securities of such series to be redeemed, or
(b) any Securities selected, called or being called for redemption except, in
the case of any Security where notice has been given that such Security is to be
redeemed in part, the portion thereof not so to be redeemed.

                                       12
<PAGE>

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

      Section 2.09. Mutilated, Defaced, Destroyed, Lost and Stolen Securities.
In case any temporary or definitive Security shall become mutilated, defaced or
be destroyed, lost or stolen, the Issuer in its discretion may execute, and upon
the written request of any officer of the Issuer, the Trustee shall authenticate
and deliver, a new Security of the same series, bearing a number not
contemporaneously outstanding, in exchange and substitution for the mutilated or
defaced Security, or in lieu of and substitution for the Security so destroyed,
lost or stolen. In every case the applicant for a substitute Security shall
furnish to the Issuer and to the Trustee and any agent of the Issuer or the
Trustee such security or indemnity as may be required by them to indemnify and
defend and to save each of them harmless and, in every case of destruction, loss
or theft, evidence to their satisfaction of the destruction, loss or theft of
such Security and of the ownership thereof in the case of mutilation or
defacement shall surrender the Security to the Trustee or such agent.

      Upon the issuance of any substitute Security, the Issuer may require the
payment of a sum sufficient to cover any tax or other governmental charge that
may be imposed in relation thereto and any other expenses (including the fees
and expenses of the Trustee or its agent) connected therewith. In case any
Security which has matured or is about to mature or has been called for
redemption in full shall become mutilated or defaced or be destroyed, lost or
stolen, the Issuer may instead of issuing a substitute Security, pay or
authorize the payment of the same (without surrender thereof except in the case
of a mutilated or defaced Security), if the applicant for such payment shall
furnish to the Issuer and the Trustee and any agent of the Issuer or the Trustee
such security or indemnity as any of them may require to save each of them
harmless, and, in every case of destruction, loss or theft, the applicant shall
also furnish to the Issuer and the Trustee and any agent of the Issuer or the
Trustee evidence to their satisfaction of the destruction, loss or theft of such
Security and of the ownership thereof.

      Every substitute Security of any series issued pursuant to the provisions
of this section by virtue of the fact that any such Security is destroyed, lost
or stolen shall constitute an additional contractual obligation of the Issuer,
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 (but shall be
subject to all the limitations of rights set forth in) this Indenture equally
and proportionately with any and all other Securities of such series duly
authenticated and delivered hereunder. All Securities shall be held and owned
upon the express condition that, to the extent permitted by law, the foregoing
provisions are exclusive with respect to the replacement or payment of
mutilated, defaced or destroyed, lost or stolen

                                       13
<PAGE>

Securities and shall preclude any and all other rights or remedies
notwithstanding any law or statute existing or hereafter enacted to the contrary
with respect to the replacement or payment of negotiable instruments or other
securities without their surrender.

      Section 2.10. Cancellation of Securities. All Securities surrendered for
payment, redemption, registration of transfer or exchange, or for credit against
any payment in respect of a sinking or analogous fund, if surrendered to the
Issuer or any agent of the Issuer or the Trustee, shall be delivered to the
Trustee for cancellation or, if surrendered to the Trustee, shall be cancelled
by it; and no Securities shall be issued in lieu thereof except as expressly
permitted by any of the provisions of this Indenture. The Trustee shall destroy
canceled Securities held by it and deliver a certificate of destruction to the
Issuer. If the Issuer shall acquire any of the Securities, such acquisition
shall not operate as a redemption or satisfaction of the indebtedness
represented by such Securities unless and until the same are delivered to the
Trustee for cancellation.

      Section 2.11. Temporary Securities. Pending the preparation of definitive
Securities for any series, the Issuer may execute and the Trustee shall
authenticate and deliver temporary Securities for such series (printed,
lithographed, typewritten or otherwise reproduced, in each case in form
satisfactory to the Trustee). Temporary Securities of any series shall be
issuable as registered Securities without coupons, of any authorized
denomination, and substantially in the form of the definitive Securities of such
series but with such omissions, insertions and variations as may be appropriate
for temporary Securities, all as may be determined by the Issuer with the
concurrence of the Trustee. Temporary Securities may contain such reference to
any provisions of this Indenture as may be appropriate. Every temporary Security
shall be executed by the Issuer and be authenticated by the Trustee upon the
same conditions and in substantially the same manner, and with like effect, as
the definitive Securities. Without unreasonable delay the Issuer shall execute
and shall furnish definitive Securities of such series and thereupon temporary
Securities of such series may be surrendered in exchange therefor without charge
at each office or agency to be maintained by the Issuer for that purpose
pursuant to Section 3.02, and the Trustee shall authenticate and deliver in
exchange for such temporary Securities of such series a like aggregate principal
amount of definitive Securities of the same series of authorized denominations.
Until so exchanged, the temporary Securities of any series shall be entitled to
the same benefits under this Indenture as definitive Securities of such series
unless otherwise established pursuant to Section 2.03.

                                    ARTICLE 3
                     COVENANTS OF THE ISSUER AND THE TRUSTEE

      Section 3.01. Payment of Principal and Interest. The Issuer covenants and
agrees for the benefit of each series of Securities that it will duly and
punctually pay or cause to be paid the principal of, and interest on, each of
the Securities of such series (together with any additional amounts payable
pursuant to the terms of such Securities) at the place or places, at the
respective times and in the manner provided in such Securities. Subject to any
other provisions that may be established pursuant to Section 2.03, the interest
on Securities (together with any additional amounts payable pursuant to the
terms of such Securities) shall be payable only to or upon the written order of
the Holders thereof and, at the option of the Issuer, may be paid by wire
transfer or by mailing checks for such interest payable to or upon the written
order of such Holders at their last addresses as they appear on the registry
books of the Issuer.

      Section 3.02. Offices for Payments, etc. So long as any of the Securities
remain outstanding, the Issuer will maintain in the Borough of Manhattan, The
City of New York, the following for each series: an office or agency (a) where
the Securities may be presented for payment, (b) where the Securities may be
presented for registration of transfer and for exchange as in this Indenture
provided and (c) where notices and demands to or upon the Issuer in respect of
the Securities or of this Indenture may be served. The Issuer will give to the
Trustee written notice of the location of any such office or agency and of any
change of location thereof. Unless otherwise specified in accordance with
Section 2.03, the Issuer hereby initially designates the Corporate Trust Office
of the Trustee, as the office to be maintained by it for each such purpose. In
case the Issuer shall fail to so designate or maintain any such office or agency
or shall fail to give such notice of the location or of any change in the
location thereof, presentations and demands may be made and notices may be
served at the Corporate Trust Office.

      The Issuer may from time to time designate one or more additional offices
or agencies where the Securities of a series may be presented for payment, where
the Securities of that series may be presented for exchange as provided in this
Indenture and pursuant to Section 2.03 and where the Securities of that series
may be presented for registration of transfer as provided in this Indenture, and
the Issuer may from time to time rescind any such designation, as the Issuer may
deem desirable or expedient; provided, however, that no such designation or
rescission shall in any manner relieve the Issuer of its obligation to maintain
the agencies provided for in this Section. The Issuer will give to the Trustee
prompt written notice of any such designation or rescission thereof.

      Section 3.03. Appointment to Fill a Vacancy in Office of Trustee. The
Issuer, whenever necessary to avoid or fill a vacancy in the office of Trustee,
will

                                       15
<PAGE>

appoint, in the manner provided in Section 5.09, a Trustee, so that there shall
at all times be a Trustee with respect to each series of Securities hereunder.

      Section 3.04. Paying Agents. Whenever the Issuer shall appoint a paying
agent other than the Trustee with respect to the Securities of any series, it
will cause such paying agent to execute and deliver to the Trustee an instrument
in which such agent shall agree with the Trustee, subject to the provisions of
this Section,

      (a) that it will hold all sums received by it as such agent for the
payment of the principal of or interest on the Securities of such series
(whether such sums have been paid to it by the Issuer or by any other obligor on
the Securities of such series) in trust for the benefit of the holders of the
Securities of such series or of the Trustee,

      (b) that it will give the Trustee notice of any failure by the Issuer (or
by any other obligor on the Securities of such series) to make any payment of
the principal of or interest on the Securities of such series when the same
shall be due and payable, and

      (c) that it will pay any such sums so held in trust by it to the Trustee
upon the Trustee's written request at any time during the continuance of the
failure referred to in clause 3.04(b) above.

      The Issuer will, on or prior to each due date of the principal of or
interest on the Securities of such series, deposit with the paying agent a sum
sufficient to pay such principal or interest so becoming due, and (unless such
paying agent is the Trustee) the Issuer will promptly notify the Trustee of any
failure to take such action.

      If the Issuer shall act as its own paying agent with respect to the
Securities of any Series, it will, on or before each due date of the principal
of or interest on the Securities of such series, set aside, segregate and hold
in trust for the benefit of the holders of the Securities of such series a sum
sufficient to pay such principal or interest so becoming due. The Issuer will
promptly notify the Trustee of any failure to take such action.

      Anything in this section to the contrary notwithstanding, the Issuer may
at any time, for the purpose of obtaining a satisfaction and discharge with
respect to one or more or all series of Securities hereunder, or for any other
reason, pay or cause to be paid to the Trustee all sums held in trust for any
such series by the Issuer or any paying agent hereunder, as required by this
Section, such sums to be held by the Trustee upon the trusts herein contained.

                                       16
<PAGE>

      Anything in this section to the contrary notwithstanding, the agreement to
hold sums in trust as provided in this section is subject to the provisions of
Section 9.03 and 9.04.

      Section 3.05. Certificate of the Issuer. The Issuer will furnish to the
Trustee on or before [__] in each year (beginning with [__]) a brief certificate
(which need not comply with Section 10.05) from the principal executive,
financial or accounting officer of the Issuer as to his or her knowledge of the
Issuer's compliance with all conditions and covenants under the Indenture (such
compliance to be determined without regard to any period of grace or requirement
of notice provided under the Indenture). If any Securities are guaranteed by a
guarantor, the guarantor shall also provide such certificates as are required by
this Section.

      Section 3.06. Securityholders Lists. If and so long as the Trustee shall
not be the Security registrar for the Securities of any series, the Issuer will
furnish or cause to be furnished to the Trustee a list in such form as the
Trustee may reasonably require of the names and addresses of the holders of the
Securities of such series pursuant to Section 312 of the Trust Indenture Act of
1939 (a) semi-annually not more than 15 days after each record date for the
payment of interest on such Securities, as hereinabove specified, as of such
record date and on dates to be determined pursuant to Section 2.03 for
non-interest bearing securities in each year, and (b) at such other times as the
Trustee may request in writing, within thirty days after receipt by the Issuer
of any such request as of a date not more than 15 days prior to the time such
information is furnished.

      Section 3.07. Reports by the Issuer. The Issuer covenants to file with the
Trustee, within 15 days after the Issuer is required to file the same with the
Commission, copies of the annual reports and of the information, documents, and
other reports that the Issuer may be required to file with the Commission
pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934.

      Section 3.08. Reports by the Trustee. Any Trustee's report required under
Section 313(a) of the Trust Indenture Act of 1939 shall be transmitted on or
before July 15 in each year following the date hereof, so long as any Securities
are outstanding hereunder, and shall be dated as of a date convenient to the
Trustee no more than 60 nor less than 45 days prior thereto.

                                    ARTICLE 4
         REMEDIES OF THE TRUSTEE AND SECURITYHOLDERS ON EVENT OF DEFAULT

furtherance of any such action; or

      (e) any other Event of Default provided in the supplemental indenture or
resolution of the Board under which such series of Securities is issued or in
the form of Security for such series.

      Unless otherwise set forth in any applicable supplemental indenture, if an
Event of Default described in clauses 4.01(a), 4.01(b), or 4.01(e) above (if the
Event of Default under clauses 4.01(b) or 4.01(e) is with respect to less than
all series of Securities then Outstanding) occurs and is continuing, then, and
in each and every such case, except for any series the principal of which shall
have already become due and payable, either the Trustee or the holders of not
less than 25% in aggregate principal amount of the Securities of all series
affected thereby then Outstanding hereunder (treated as one class) by notice in
writing to the Issuer (and to the Trustee if given by Securityholders), may
declare the entire principal (or, if the Securities of any such affected series
are Original Issue Discount Securities, such portion of the principal amount as
may be specified in the terms of such series) of all Securities of such affected
series and the interest accrued thereon, if any, to be due and payable
immediately, and upon any such declaration the same shall become immediately due
and payable. Unless otherwise set forth in any applicable supplemental
indenture, if an Event of Default described in clauses 4.01(b) or 4.01(e) (if
the Event of Default under clauses 4.01(b) or 4.01(e) is with respect to all
series of Securities at the time Outstanding) occurs and is continuing, then and
in each and every such case, unless the principal of all the Securities shall
have already become due and payable, either the Trustee or the holders of not
less than 25% in aggregate principal amount of all the then Outstanding
Securities hereunder (treated as one class) for which any applicable
supplemental indenture does not prevent acceleration under the relevant
circumstances, by notice in writing to the Issuer and the Guarantor (and to the
Trustee if given by Securityholders), may declare the entire principal (or, if
any Securities are Original Issue Discount Securities, such portion of the
principal as may be specified in the terms thereof) of all the Securities then
Outstanding and interest accrued thereon, if any, to be due and payable
immediately, and upon any such declaration the same shall become immediately due
and payable. Unless otherwise set forth in any applicable supplemental
indenture, if an Event of Default described in clauses 4.01(c) or 4.01(d), then
the principal and accrued and

                                       19
<PAGE>

unpaid interest, and premium of any, with respect to any Securities then
Outstanding shall ipso facto become and be immediately due and payable without
any declaration or other act on the part of the Trustee or any Holder.

      The foregoing provisions, however, are subject to the condition that if,
at any time after the principal (or, if the Securities are Original Issue
Discount Securities, such portion of the principal as may be specified in the
terms thereof) of the Securities of any series (or of all the Securities, as the
case may be) shall have been so declared due and payable, and before any
judgment or decree for the payment of the moneys due shall have been obtained or
entered as hereinafter provided, the Issuer shall pay or shall deposit with the
Trustee a sum sufficient to pay all matured installments of interest upon all
the Securities of such series (or of all the Securities, as the case may be) and
the principal of any and all Securities of such series (or of all the
Securities, as the case may be) which shall have become due otherwise than by
acceleration (with interest upon such principal and, to the extent that payment
of such interest is enforceable under applicable law, on overdue installments of
interest, at the same rate as the rate of interest or Yield to Maturity (in the
case of Original Issue Discount Securities) specified in the Securities of such
series (or at the respective rates of interest or Yields to Maturity of all the
Securities, as the case may be) to the date of such payment or deposit) and such
amount as shall be sufficient to cover reasonable compensation to the Trustee,
its agents, attorneys and counsel, and all other expenses and liabilities
incurred, and all advances made, by the Trustee except as a result of negligence
or bad faith, and if any and all Events of Default under the Indenture, other
than the non-payment of the principal of Securities which shall have become due
by acceleration, shall have been cured, waived or otherwise remedied as provided
herein--then and in every such case the holders of a majority in aggregate
principal amount of all the Securities of each such series (or of all the
Securities, as the case may be), then Outstanding (in each case treated as one
class), by written notice to the Issuer and to the Trustee, may waive all
defaults with respect to each such series (or with respect to all the
Securities, as the case may be) and rescind and annul such declaration and its
consequences, but no such waiver or rescission and annulment shall extend to or
shall affect any subsequent default or shall impair any right consequent
thereon.

      For all purposes under this Indenture, if a portion of the principal of
any Original Issue Discount Securities shall have been accelerated and declared
due and payable pursuant to the provisions hereof, then, from and after such
declaration, unless such declaration has been rescinded and annulled, the
principal amount of such Original Issue Discount Securities shall be deemed, for
all purposes hereunder, to be such portion of the principal thereof as shall be
due and payable as a result of such acceleration, and payment of such portion of
the principal thereof as shall be due and payable as a result of such
acceleration, together with interest, if any, thereon and all other amounts
owing thereunder, shall constitute payment in full of such Original Issue
Discount Securities.

      Section 4.02. Collection of Indebtedness by Trustee; Trustee May Prove
Debt. The Issuer covenants that (a) in case default shall be made in the payment
of any installment of interest on any of the Securities of any series when such
interest shall have become due and payable, and such default shall have
continued for a period of 30 days or (b) in case default shall be made in the
payment of all or any part of the principal of any of the Securities of any
series when the same shall have become due and payable, whether upon maturity of
the Securities of such series or upon any redemption or by declaration or
otherwise--then upon demand of the Trustee, the Issuer will pay to the Trustee
for the benefit of the Holders of the Securities of such series the whole amount
that then shall have become due and payable on all Securities of series for
principal or interest, as the case may be (with interest to the date of such
payment upon the overdue principal and, to the extent that payment of such
interest is enforceable under applicable law, on overdue installments of
interest at the same rate as the rate of interest or Yield to Maturity (in the
case of Original Issue Discount Securities) specified in the Securities of such
series); and in addition thereto, such further amount as shall be sufficient to
cover the costs and expenses of collection, including reasonable compensation to
the Trustee and each predecessor Trustee, their respective agents, attorneys and
counsel, and any expenses and liabilities incurred, and all advances made, by
the Trustee and each predecessor Trustee except as a result of its negligence or
bad faith.

      Until such demand is made by the Trustee, the Issuer may pay the principal
of and interest on the Securities of any series to the registered holders,
whether or not the principal of and interest on the Securities of such series be
overdue.

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

      In case there shall be pending proceedings relative to the Issuer or any
other obligor upon the Securities under Title 11 of the United States Code or
any other applicable Federal or state bankruptcy, insolvency or other similar
law, or in case a receiver, assignee or trustee in bankruptcy or reorganization,
liquidator, sequestrator or similar official shall have been appointed for or
taken possession of the Issuer or its property or such other obligor, or in case
of any other comparable judicial proceedings relative to the Issuer or other
obligor upon the Securities of any series, or to the creditors or property of
the Issuer or such other

                                       21
<PAGE>

obligor, the Trustee, irrespective of whether the principal of any Securities
shall then be due and payable as therein expressed or by declaration or
otherwise and irrespective of whether the Trustee shall have made any demand
pursuant to the provisions of this Section, shall be entitled and empowered, by
intervention in such proceedings or otherwise:

            (a) to file and prove a claim or claims for the whole amount of
      principal and interest (or, if the Securities of any series are Original
      Issue Discount Securities, such portion of the principal amount as may be
      specified in the terms of such series) owing and unpaid in respect of the
      Securities of any series, and to file such other papers or documents as
      may be necessary or advisable in order to have the claims of the Trustee
      (including any claim for reasonable compensation to the Trustee and each
      predecessor Trustee, and their respective agents, attorneys and counsel,
      and for reimbursement of all expenses and liabilities incurred, and all
      advances made, by the Trustee and each predecessor Trustee, except as a
      result of negligence or bad faith) and of the Securityholders allowed in
      any judicial proceedings relative to the Issuer or other obligor upon the
      Securities of any series, or to the creditors or property of the Issuer or
      such other obligor,

            (b) unless prohibited by applicable law and regulations, to vote on
      behalf of the holders of the Securities of any series in any election of a
      trustee or a standby trustee in arrangement, reorganization, liquidation
      or other bankruptcy or insolvency proceedings or person performing similar
      functions in comparable proceedings, and

            (c) to collect and receive any moneys or other property payable or
      deliverable on any such claims, and to distribute all amounts received
      with respect to the claims of the Securityholders and of the Trustee on
      their behalf; and any trustee, receiver, or liquidator, custodian or other
      similar official is hereby authorized by each of the Securityholders to
      make payments to the Trustee, and, in the event that the Trustee shall
      consent to the making of payments directly to the Securityholders, to pay
      to the Trustee such amounts as shall be sufficient to cover reasonable
      compensation to the Trustee, each predecessor Trustee and their respective
      agents, attorneys and counsel, and all other expenses and liabilities
      incurred, and all advances made, by the Trustee and each predecessor
      Trustee except as a result of negligence or bad faith.

      Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or vote for or accept or adopt on behalf of any
Securityholder any plan or reorganization, arrangement, adjustment or
composition affecting the Securities of any series or the rights of any Holder
thereof, or to authorize the Trustee to vote in respect of the claim of any

                                       22
<PAGE>

Securityholder in any such proceeding except, as aforesaid, to vote for the
election of a trustee in bankruptcy or similar person.

      All rights of action and of asserting claims under this Indenture, or
under any of the Securities, may be enforced by the Trustee without the
possession of any of the Securities or the production thereof on any trial or
other proceedings relative thereto, and any such action or proceedings
instituted by the Trustee shall be brought in its own name as trustee of an
express trust, and any recovery of judgment, subject to the payment of the
expenses, disbursements and compensation of the Trustee, each predecessor
Trustee and their respective agents and attorneys, shall be for the ratable
benefit of the holders of the Securities in respect of which such action was
taken.

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

      Section 4.03. Application of Proceeds. Any moneys collected by the Trustee
pursuant to this Article in respect of any series shall be applied in the
following order at the date or dates fixed by the Trustee and, in case of the
distribution of such moneys on account of principal or interest, upon
presentation of the several Securities in respect of which monies have been
collected and stamping (or otherwise noting) thereon the payment, or issuing
Securities of such series in reduced principal amounts in exchange for the
presented Securities of like series if only partially paid, or upon surrender
thereof if fully paid:

            FIRST: To the payment of costs and expenses applicable to such
      series in respect of which monies have been collected, including
      reasonable compensation to the Trustee and each predecessor Trustee and
      their respective agents and attorneys and of all expenses and liabilities
      incurred, and all advances made, by the Trustee and each predecessor
      Trustee except as a result of negligence or bad faith;

            SECOND: In case the principal of the Securities of such series in
      respect of which moneys have been collected shall not have become and be
      then due and payable, to the payment of interest on the Securities of such
      series in default in the order of the maturity of the installments of such
      interest, with interest (to the extent that such interest has been
      collected by the Trustee) upon the overdue installments of interest at the
      same rate as the rate of interest or Yield to Maturity (in the case of
      Original Issue Discount Securities) specified in such Securities, such
      payments to be made ratably to the persons entitled thereto, without
      discrimination or preference;

                                       23
<PAGE>

            THIRD: In case the principal of the Securities of such series in
      respect of which moneys have been collected shall have become and shall be
      then due and payable, to the payment of the whole amount then owing and
      unpaid upon all the Securities of such series for principal and interest,
      with interest upon the overdue principal, and (to the extent that such
      interest has been collected by the Trustee) upon overdue installments of
      interest at the same rate as the rate of interest or Yield to Maturity (in
      the case of Original Issue Discount Securities) specified in the
      Securities of such series; and in case such moneys shall be insufficient
      to pay in full the whole amount so due and unpaid upon the Securities of
      such series, then to the payment of such principal and interest or Yield
      to Maturity, without preference or priority of principal over interest or
      Yield to Maturity, or of interest or Yield to Maturity over principal, or
      of any installment of interest over any other installment of interest, or
      of any Security of such series over any other Security of such series,
      ratably to the aggregate of such principal and accrued and unpaid interest
      or Yield to Maturity; and

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

      Section 4.04. Suits for Enforcement. In case an Event of Default has
occurred, has not been waived and is continuing, the Trustee may in its
discretion proceed to protect and enforce the rights vested in it by this
Indenture by such appropriate judicial proceedings as the Trustee shall deem
most effectual to protect and enforce any of such rights, either at law or in
equity or in bankruptcy or otherwise, whether for the specific enforcement of
any covenant or agreement contained in this Indenture or in aid of the exercise
of any power granted in this Indenture or to enforce any other legal or
equitable right vested in the Trustee by this Indenture or by law.

      Section 4.05. Restoration of Rights on Abandonment of Proceeding. In case
the Trustee shall have proceeded to enforce any right under this Indenture and
such proceedings shall have been discontinued or abandoned for any reason, or
shall have been determined adversely to the Trustee, then and in every such case
the Issuer and the Trustee shall be restored respectively to their former
positions and rights hereunder, and all rights, remedies and powers of the
Issuer, the Trustee and the Securityholders shall continue as though no such
proceedings had been taken.

      Section 4.06. Limitations on Suits by Securityholder. No holder of any
Security of any series shall have any right by virtue or by availing of any
provision of this Indenture to institute any action or proceeding at law or in
equity or in bankruptcy or otherwise upon or under or with respect to this
Indenture, or for the appointment of a trustee, receiver, liquidator, custodian
or other similar official or for any other remedy hereunder, unless such Holder
previously shall

                                       24
<PAGE>

have given to the Trustee written notice of default and of the continuance
thereof, as hereinbefore provided, and unless also the Holders of not less than
25% in aggregate principal amount of the Securities of each affected series then
Outstanding (treated as a single class) shall have made written request upon the
Trustee to institute such action or proceedings in its own name as trustee
hereunder and shall have offered to the Trustee such reasonable indemnity as it
may require against the costs, expenses and liabilities to be incurred therein
or thereby and the Trustee for 60 days after its receipt of such notice, request
and offer of indemnity shall have failed to institute any such action or
proceeding and no direction inconsistent with such written request shall have
been given to the Trustee pursuant to Section 4.09; it being understood and
intended, and being expressly covenanted by the taker and Holder of every
Security with every other taker and Holder and the Trustee, that no one or more
Holders of Securities of any series shall have any right in any manner whatever
by virtue or by availing of any provision of this Indenture to affect, disturb
or prejudice the rights of any other such Holder of Securities, or to obtain or
seek to obtain priority over or preference to any other such Holder or to
enforce any right under this Indenture, except in the manner herein provided and
for the equal, ratable and common benefit of all Holders of Securities of the
applicable series. For the protection and enforcement of the provisions of this
Section, each and every Securityholder and the Trustee shall be entitled to such
relief as can be given either at law or in equity.

      Section 4.07. Unconditional Right of Securityholders to Institute Certain
Suits. Notwithstanding any other provision in this Indenture and any provision
of any Security, the right of any Holder of any Security to receive payment of
the principal of and interest on such Security on or after the respective due
dates expressed in such Security, or to institute suit for the enforcement of
any such payment on or after such respective dates, shall not be impaired or
affected without the consent of such Holder.

      Section 4.08. Powers and Remedies Cumulative; Delay or Omission Not Waiver
of Default. Except as provided in Section 4.06, no right or remedy herein
conferred upon or reserved to the Trustee or to the Securityholders 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.

      No delay or omission of the Trustee or of any Securityholder to exercise
any right or power accruing upon any Event of Default occurring and continuing
as aforesaid shall impair any such right or power or shall be construed to be a
waiver of any such Event of Default or an acquiescence therein; and, subject to
Section 4.06, every power and remedy given by this Indenture or by law to the

                                       25
<PAGE>

Trustee or to the Securityholders may be exercised from time to time, and as
often as shall be deemed expedient, by the Trustee or by the Securityholders.

      Section 4.09. Control by Securityholders. The Holders of a majority in
aggregate principal amount of the Securities of each series affected (with all
such series voting as a single class) at the time Outstanding 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 by this Indenture;
provided that such direction shall not be otherwise than in accordance with law
and the provisions of this Indenture and provided further that (subject to the
provisions of Section 5.01) the Trustee shall have the right to decline to
follow any such direction if the Trustee, being advised by counsel, shall
determine that the action or proceeding so directed may not lawfully be taken or
if the Trustee in good faith by its board of directors, the executive committee,
or a trust committee of directors or Responsible Officers of the Trustee shall
determine that the action or proceedings so directed would involve the Trustee
in personal liability or if the Trustee in good faith shall so determine that
the actions or forebearances specified in or pursuant to such direction would be
unduly prejudicial to the interests of Holders of the Securities of all series
so affected not joining in the giving of said direction, it being understood
that (subject to Section 5.01) the Trustee shall have no duty to ascertain
whether or not such actions or forebearances are unduly prejudicial to such
Holders. Nothing in this Indenture shall impair the right of the Trustee in its
discretion to take any action deemed proper by the Trustee and which is not
inconsistent with such direction or directions by Securityholders.

      Section 4.10. Waiver of Past Defaults. Prior to the acceleration of the
maturity of any Securities as provided in Section 4.01, the Holders of a
majority in aggregate principal amount of the Securities of all series at the
time Outstanding with respect to which an Event of Default shall have occurred
and be continuing (voting as a single class) may on behalf of the Holders of all
such Securities waive any past default or Event of Default described in Section
4.01 and its consequences, except a default in respect of a covenant or
provision hereof which cannot be modified or amended without the consent of the
Holder of each Security affected. In the case of any such waiver, the Issuer,
the Guarantor, the Trustee and the Holders of all such Securities shall be
restored to their former positions and rights hereunder, respectively; but no
such waiver shall extend to any subsequent or other default or impair any right
consequent thereon.

      Upon any such waiver, such default shall cease to exist and be deemed to
have been cured and not to have occurred, and any Event of Default arising
therefrom shall be deemed to have been cured, and not to have occurred for every

                                       26
<PAGE>

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 4.11. Trustee to Give Notice of Default, But May Withhold in
Certain Circumstances. The Trustee shall give to the Securityholders of any
series, as the names and addresses of such Holders appear on the registry books,
notice by mail of all defaults known to the Trustee which have occurred with
respect to such series, such notice to be transmitted within 90 days after the
occurrence thereof, unless such defaults shall have been cured before the giving
of such notice (the term "default" or "defaults" for the purposes of this
section being hereby defined to mean any event or condition which is, or with
notice or lapse of time or both would become, an Event of Default); provided
that, except in the case of default in the payment of the principal of or
interest on any of the Securities of such series, or in the payment of any
sinking or purchase fund installment with respect to the Securities of such
series, the Trustee shall be protected in withholding such notice if and so long
as the board of directors, the executive committee, or a trust committee of
directors or trustees and/or Responsible Officers of the Trustee in good faith
determines that the withholding of such notice is in the interests of the
Securityholders of such series.

      Section 4.12. Right of Court to Require Filing of Undertaking to Pay
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 in any suit against the Trustee for any action taken, suffered
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 Securityholder or group of
Securityholders of any series holding in the aggregate more than 10% in
aggregate principal amount of the Securities of such series, or, in the case of
any suit relating to or arising under clauses 4.01(b) or 4.01(e) (if the suit
relates to Securities of more than one but less than all series), 10% in
aggregate principal amount of Securities Outstanding affected thereby, or in the
case of any suit relating to or arising under clauses 4.01(b) or 4.01(e) (if the
suit relates to all the Securities then Outstanding), 4.01(c) or 4.01(d), 10% in
aggregate principal amount of all Securities Outstanding, or to any suit
instituted by any Securityholder for the enforcement of the payment of the
principal of or interest on any Security on or after the due date expressed in
such Security.

                             CONCERNING THE TRUSTEE

      Section 5.01. Duties and Responsibilities of the Trustee; During Default;
Prior to Default. With respect to the Holders of any series of Securities
issued hereunder, the Trustee, prior to the occurrence of an Event of Default
with respect to the Securities of a particular series and after the curing or
waiving of all Events of Default which may have occurred with respect to such
series, undertakes to perform such duties and only such duties as are
specifically set forth in this Indenture. In case an Event of Default with
respect to the Securities of a series has occurred (which has not been cured or
waived) the Trustee shall exercise with respect to such series of Securities
such of the rights and powers vested in it by this Indenture, and use the same
degree of care and skill in their exercise, as a prudent person would exercise
or use under the circumstances in the conduct of his or her own affairs.

      No provision of this Indenture shall be construed to relieve the Trustee
from liability for its own negligent action, its own negligent failure to act or
its own willful misconduct, except that

      (a) prior to the occurrence of an Event of Default with respect to the
Securities of any series and after the curing or waiving of all such Events of
Default with respect to such series which may have occurred:

            (i) the duties and obligations of the Trustee with respect to the
      Securities of any Series shall be determined solely by the express
      provisions of this Indenture, and the Trustee shall not be liable except
      for the performance of such duties and obligations as are specifically set
      forth in this Indenture, and no implied covenants or obligations shall be
      read into this Indenture against the Trustee; and

            (ii) in the absence of bad faith on the part of the Trustee, the
      Trustee may conclusively rely, as to the truth of the statements and the
      correctness of the opinions expressed therein, upon any statements,
      certificates or opinions furnished to the Trustee and conforming to the
      requirements of this Indenture; but in the case of any such statements,
      certificates or opinions which by any provision hereof are specifically
      required to be furnished to the Trustee, the Trustee shall be under a duty
      to examine the same to determine whether or not they conform to the
      requirements of this Indenture;

      (b) the Trustee shall not be liable for any error of judgment made in good
faith by a Responsible Officer or Responsible Officers of the Trustee, unless it
shall be proved that the Trustee was negligent in ascertaining the pertinent
facts; and

                                       28
<PAGE>

      (c) the Trustee shall not be liable with respect to any action taken or
omitted to be taken by it in good faith in accordance with the direction of the
holders pursuant to Section 4.09 relating to the time, method and place of
conducting any proceeding for any remedy available to the Trustee, or exercising
any trust or power conferred upon the Trustee, under this Indenture.

      None of the provisions contained in this Indenture shall require the
Trustee to expend or risk its own funds or otherwise incur personal financial
liability in the performance of any of its duties or in the exercise of any of
its rights or powers, if there shall be reasonable ground for believing that the
repayment of such funds or adequate indemnity against such liability is not
reasonably assured to it.

      The provisions of this Section 5.01 are in furtherance of and subject to
Sections 315 and 316 of the Trust Indenture Act of 1939.

      Section 5.02. Certain Rights of the Trustee. In furtherance of and subject
to the Trust Indenture Act of 1939, and subject to Section 5.01:

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

      (b) any request, direction, order or demand of the Issuer mentioned herein
shall be sufficiently evidenced by an Officers' Certificate (unless other
evidence in respect thereof be herein specifically prescribed); and any
resolution of the Board may be evidenced to the Trustee by a copy thereof
certified by the secretary or an assistant secretary of the Issuer;

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

      (d) the Trustee shall be under no obligation to exercise any of the trusts
or powers vested in it by this Indenture at the request, order or direction of
any of the Securityholders pursuant to the provisions of this Indenture, unless
such Securityholders shall have offered to the Trustee reasonable security or
indemnity against the costs, expenses and liabilities which might be incurred
therein or thereby;

                                       29
<PAGE>

      (e) the Trustee shall not be liable for any action taken or omitted by it
in good faith and believed by it to be authorized or within the discretion,
rights or powers conferred upon it by this Indenture;

      (f) prior to the occurrence of an Event of Default hereunder and after the
curing or waiving of all Events of Default, 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, consent,
order, approval, appraisal, bond, debenture, note, coupon, security, or other
paper or document unless requested in writing so to do by the holders of not
less than a majority in aggregate principal amount of the Securities of all
series affected then outstanding; provided that, if the payment within a
reasonable time to the Trustee of the costs, expenses or liabilities likely to
be incurred by it in the making of such investigation is, in the opinion of the
Trustee, not reasonably assured to the Trustee by the security afforded to it by
the terms of this Indenture, the Trustee may require reasonable indemnity
against such expenses or liabilities as a condition to proceeding; the
reasonable expenses of every such investigation shall be paid by the Issuer or,
if paid by the Trustee or any predecessor trustee, shall be repaid by the Issuer
upon demand; and

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

      Section 5.03. Trustee Not Responsible for Recitals, Disposition of
Securities or Application of Proceeds Thereof. The recitals contained herein and
in the Securities, except the Trustee's certificates of authentication, shall be
taken as the statements of the Issuer, and the Trustee assumes no responsibility
for the correctness of the same. The Trustee makes no representation as to the
validity or sufficiency of this Indenture or of the Securities. The Trustee
shall not be accountable for the use or application by the Issuer of any of the
Securities or of the proceeds thereof.

      Section 5.04. Trustee and Agents May Hold Securities; Collections, etc.
The Trustee or any agent of the Issuer or the Trustee, in its individual or any
other capacity, may become the owner or pledgee of Securities with the same
rights it would have if it were not the Trustee or such agent and may otherwise
deal with the Issuer and receive, collect, hold and retain collections from the
Issuer with the same rights it would have if it were not the Trustee or such
agent.

      Section 5.05. Moneys Held by Trustee. Subject to the provisions of Section
9.04 hereof, all moneys received by the Trustee shall, until used or applied as
herein provided, be held in trust for the purposes for which they were

                                       30
<PAGE>

received, but need not be segregated from other funds except to the extent
required by mandatory provisions of law. Neither the Trustee nor any agent of
the Issuer or the Trustee shall be under any liability for interest on any
moneys received by it hereunder.

      Section 5.06. Compensation and Indemnification of Trustee and its Prior
Claim. The Issuer covenants and agrees to pay to the Trustee from time to time,
and the Trustee shall be entitled to, reasonable compensation (which shall not
be limited by any provision of law in regard to the compensation of a trustee of
an express trust) and the Issuer covenants and agrees to pay or reimburse the
Trustee and each predecessor Trustee upon its request for all reasonable
expenses, disbursements and advances incurred or made by or on behalf of it in
accordance with any of the provisions of this Indenture (including the
reasonable compensation and the expenses and disbursements of its counsel and of
all agents and other persons not regularly in its employ) except to the extent
any such expense, disbursement or advance may arise from its negligence or bad
faith. The Issuer also covenants to indemnify the Trustee and each predecessor
Trustee for, and to hold it harmless against, any loss, liability or expense
arising out of or in connection with the acceptance or administration of this
Indenture or the trusts hereunder and the performance of its duties hereunder,
including the costs and expenses of defending itself against or investigating
any claim of liability in the premises, except to the extent such loss liability
or expense is due to the negligence or bad faith of the Trustee, its agents or
employees or such predecessor Trustee. The obligations of the Issuer under this
section to compensate and indemnify the Trustee and each predecessor Trustee and
to pay or reimburse the Trustee and each predecessor Trustee for expenses,
disbursements and advances shall constitute additional indebtedness hereunder
and shall survive the satisfaction and discharge of this Indenture. Such
additional indebtedness shall be a senior claim to that of the Securities upon
all property and funds held or collected by the Trustee as such, except funds
held in trust for the benefit of the holders of particular Securities, and the
Securities are hereby subordinated to such senior claim.

      Section 5.07. Right of Trustee to Reply on Officers' Certificate, etc.
Subject to Sections 5.01 and 5.02, whenever in the administration of the trusts
of this Indenture the Trustee shall deem it necessary or desirable that a matter
be proved or established prior to taking or suffering or omitting any action
hereunder, such matter (unless other evidence in respect thereof be herein
specifically prescribed) may, in the absence of negligence or bad faith on the
part of the Trustee, be deemed to be conclusively proved and established by an
Officers' Certificate delivered to the Trustee, and such certificate, in the
absence of negligence or bad faith on the part of the Trustee, shall be full
warrant to the Trustee for any action taken, suffered or omitted by it under the
provisions of this Indenture upon the faith thereof.

      Section 5.08. Persons Eligible for Appointment as Trustee. The Trustee for
each series of Securities hereunder shall at all times be a corporation
organized and doing business under the laws of the United States of America or
the District of Columbia having a combined capital and surplus of at least
$50,000,000, and which is eligible in accordance with the provisions of Section
310(a) of the Trust Indenture Act of 1939. If such corporation publishes reports
of condition at least annually, pursuant to law or to the requirements of a
Federal, State or District of Columbia supervising or examining authority, then
for the purposes of this Section, the combined capital and surplus of such
corporation shall be deemed to be its combined capital and surplus as set forth
in its most recent report of condition so published.

      Section 5.09. Resignation and Removal; Appointment of Successor Trustee.
(a) The Trustee, or any trustee or trustees hereafter appointed, may at any time
resign with respect to one or more or all series of Securities by giving written
notice of resignation to the Issuer and by mailing notice thereof by first class
mail to Holders of the applicable series of Securities at their last addresses
as they shall appear on the Security register. Upon receiving such notice of
resignation, the Issuer shall promptly appoint a successor trustee or trustees
with respect to the applicable series by written instrument in duplicate,
executed by authority of the Board, one copy of which instrument shall be
delivered to the resigning Trustee and one copy to the successor trustee or
trustees. If no successor trustee shall have been so appointed with respect to
any series and have accepted appointment within 30 days after the mailing of
such notice of resignation, the resigning trustee may petition any court of
competent jurisdiction for the appointment of a successor trustee, or any
Securityholder who has been a bona fide Holder of a Security or Securities of
the applicable series for at least six months may, subject to the provisions of
Section 4.12, on behalf of himself and all others similarly situated, petition
any such court for the appointment of a successor trustee. Such court may
thereupon, after such notice, if any, as it may deem proper and prescribe,
appoint a successor trustee.

      (b) In case at any time any of the following shall occur:

            (i) the Trustee shall fail to comply with the provisions of Section
      310(b) of the Trust Indenture Act of 1939 with respect to any series of
      Securities after written request therefor by the Issuer or by any
      Securityholder who has been a bona fide Holder of a Security or Securities
      of such series for at least six months; or

            (ii) the Trustee shall cease to be eligible in accordance with the
      provisions of Section 310(a) of the Trust Indenture Act of 1939 and shall
      fail to resign after written request therefor by the Issuer or by any
      Securityholder; or

                                       32
<PAGE>

            (iii) the Trustee shall become incapable of acting with respect to
      any series of Securities, or shall be adjudged a bankrupt or insolvent, or
      a receiver or liquidator 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, the Issuer may remove the Trustee with respect to the
applicable series of Securities and appoint a successor trustee for such series
by written instrument, in duplicate, executed by order of the Board of the
Issuer, one copy of which instrument shall be delivered to the Trustee so
removed and one copy to the successor trustee, or, subject to Section 315(e) of
the Trust Indenture Act of 1939, any Securityholder who has been a bona fide
Holder of a Security or Securities 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 removal of the Trustee and the appointment of a
successor trustee with respect to such series. Such court may thereupon, after
such notice, if any, as it may deem proper and prescribe, remove the Trustee and
appoint a successor trustee.

      (c) The Holders of a majority in aggregate principal amount of the
Securities of each series at the time outstanding may at any time remove the
Trustee with respect to Securities of such series and appoint a successor
trustee with respect to the Securities of such series by delivering to the
Trustee so removed, to the successor trustee so appointed and to the Issuer the
evidence provided for in Section 6.01 of the action in that regard taken by the
Securityholders.

      (d) Any resignation or removal of the Trustee with respect to any series
and any appointment of a successor trustee with respect to such series pursuant
to any of the provisions of this Section 5.09 shall become effective upon
acceptance of appointment by the successor trustee as provided in Section 5.10.

      Section 5.10. Acceptance of Appointment By Successor Trustee. Any
successor trustee appointed as provided in Section 5.09 shall execute and
deliver to the Issuer and to its predecessor trustee an instrument accepting
such appointment hereunder, and thereupon the resignation or removal of the
predecessor trustee with respect to all or any applicable series shall become
effective and such successor trustee, without any further act, deed or
conveyance, shall become vested with all rights, powers, duties

                                       33
<PAGE>

and obligations with respect to such series of its predecessor hereunder, with
like effect as if originally named as trustee for such series hereunder; but,
nevertheless, on the written request of the Issuer or of the successor trustee,
upon payment of its charges then unpaid, the trustee ceasing to act shall,
subject to Section 9.04, pay over to the successor trustee all moneys at the
time held by it hereunder and shall execute and deliver an instrument
transferring to such successor trustee all such rights, powers, duties and
obligations. Upon request of any such successor trustee, the Issuer shall
execute any and all instruments in writing for more fully and certainly vesting
in and confirming to such successor trustee all such rights and powers. Any
trustee ceasing to act shall, nevertheless, retain a prior claim upon all
property or funds held or collected by such trustee to secure any amounts then
due it pursuant to the provisions of Section 5.06.

      If a successor trustee is appointed with respect to the Securities of one
or more (but not all) series, the Issuer, the predecessor Trustee and each
successor trustee with respect to the Securities of any applicable series shall
execute and deliver an indenture supplemental hereto which shall contain such
provisions as shall be deemed necessary or desirable to confirm that all the
rights, powers, trusts and duties of the predecessor Trustee with respect to the
Securities of any series as to which the predecessor Trustee is not retiring
shall continue to be vested in the predecessor Trustee, and 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 under separate
indentures.

      Upon acceptance of appointment by any successor trustee as provided in
this Section 5.10, the Issuer shall mail notice thereof by first-class mail to
the Holders of Securities of any series for which such successor trustee is
acting as trustee at their last addresses as they shall appear in the Security
register. If the acceptance of appointment is substantially contemporaneous with
the resignation, then the notice called for by the preceding sentence may be
combined with the notice called for by Section 5.09. If the Issuer fails to mail
such notice within ten days after acceptance of appointment by the successor
trustee, the successor trustee shall cause such notice to be mailed at the
expense of the Issuer.

      Section 5.11. Merger, Conversion, Consolidation or Succession to Business
of Trustee. 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 the corporate trust business of the Trustee, shall be
the successor of the Trustee hereunder, provided that such corporation shall be
eligible under the provisions of Section 5.08, without the execution or filing
of any paper or any further act on the part of any of the parties hereto,
anything herein to the contrary notwithstanding.

      In case at the time such successor to the Trustee shall succeed to the
trusts created by this Indenture any of the Securities of any series shall have
been authenticated but not delivered, any such successor to the Trustee may
adopt the certificate of authentication of any predecessor Trustee and deliver
such Securities

                                       34
<PAGE>

so authenticated; and, in case at that time any of the Securities of any series
shall not have been authenticated, any successor to the Trustee may authenticate
such Securities either in the name of any predecessor hereunder or in the name
of the successor Trustee; and in all such cases such certificate shall have the
full force which it is anywhere in the Securities of such series or in this
Indenture provided that the certificate of the Trustee shall have; provided,
that the right to adopt the certificate of authentication of any predecessor
Trustee or to authenticate Securities of any series in the name of any
predecessor Trustee shall apply only to its successor or successors by merger,
conversion or consolidation.

                                    ARTICLE 6
                         CONCERNING THE SECURITYHOLDERS

      Section 6.01. Evidence of Action Taken by Securityholders. 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 Securityholders 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 Securityholders 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 Sections 5.01 and 5.02) conclusive in favor of the Trustee and the
Issuer, if made in the manner provided in this Article.

      Section 6.02. Proof of Execution of Instruments and of Holding of
Securities; Record Date. Subject to Sections 5.01 and 5.02, the execution of any
instrument by a Securityholder 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. The holding of
Securities shall be proved by the Security register or by a certificate of the
registrar thereof. The Issuer may set a record date for purposes of determining
the identity of holders of Securities of any series entitled to vote or consent
to any action referred to in Section 6.01, which record date may be set at any
time or from time to time by notice to the Trustee, for any date or dates (in
the case of any adjournment or reconsideration) not more than 60 days nor less
than five days prior to the proposed date of such vote or consent, and
thereafter, notwithstanding any other provisions hereof, only holders of
Securities of such series of record on such record date shall be entitled to so
vote or give such consent or revoke such vote or consent.

      Section 6.03. Holders to be Treated as Owners. The Issuer, the Trustee and
any agent of the Issuer or the Trustee may deem and treat the person in whose

                                       35
<PAGE>

name any Security shall be registered upon the Security register for such series
as the absolute owner of such Security (whether or not such Security shall be
overdue and notwithstanding any notation of ownership or other writing thereon)
for the purpose of receiving payment of or on account of the principal of and,
subject to the provisions of this Indenture, interest on such Security and for
all other purposes; and neither the Issuer nor the Trustee nor any agent of the
Issuer or the Trustee shall be affected by any notice to the contrary. All such
payments so made to any such person, or upon his order, shall be valid, and, to
the extent of the sum or sums so paid, effectual to satisfy and discharge the
liability for moneys payable upon any such Security.

      Section 6.04. Securities Owned by Issuer Deemed Not Outstanding. In
determining whether the Holders of the requisite aggregate principal amount of
Outstanding Securities of any or all series have concurred in any direction,
consent or waiver under this Indenture, Securities which are owned by the Issuer
or any other obligor on the Securities with respect to which such determination
is being made or by any person directly or indirectly controlling or controlled
by or under direct or indirect common control with the Issuer or any other
obligor on the Securities with respect to which such determination is being made
shall be disregarded and deemed not to be Outstanding for the purpose of any
such determination, except that for the purpose of determining whether the
Trustee shall be protected in relying on any such direction, consent or waiver
only Securities which the Trustee knows are so owned shall be so disregarded.
Securities so owned which have been pledged in good faith may be regarded as
Outstanding if the pledgee establishes to the satisfaction of the Trustee the
pledgee's right so to act with respect to such Securities and that the pledgee
is not the Issuer or any other obligor upon the Securities or any person
directly or indirectly controlling or controlled by or under direct or indirect
common control with the Issuer or any other obligor on the Securities. In case
of a dispute as to such right, the advice of counsel shall be full protection in
respect of any decision made by the Trustee in accordance with such advice. Upon
request of the Trustee, the Issuer shall furnish to the Trustee promptly an
Officers' Certificate listing and identifying all Securities, if any, known by
the Issuer to be owned or held by or for the account of any of the
above-described persons; and, subject to Sections 5.01 and 5.02, the Trustee
shall be entitled to accept such Officers' Certificate as conclusive evidence of
the facts therein set forth and of the fact that all Securities not listed
therein are Outstanding for the purpose of any such determination.

      Section 6.05. Right of Revocation of Action Taken. At any time prior to
(but not after) the evidencing to the Trustee, as provided in Section 6.01, of
the taking of any action by the Holders of the percentage in aggregate principal
amount of the Securities of any or all series, as the case may be, specified in
this Indenture in connection with such action, any Holder of a Security the
serial number of which is shown by the evidence to be included among the serial

                                       36
<PAGE>

numbers of the Securities the Holders of which have consented to such action
may, by filing written notice at the Corporate Trust Office and upon proof of
holding as provided in this Article, revoke such action so far as concerns such
Security. Except as aforesaid any such action taken by the Holder of any
Security shall be conclusive and binding upon such Holder and upon all future
Holders and owners of such Security and of any Securities issued in exchange or
substitution therefor or on registration of transfer thereof, irrespective of
whether or not any notation in regard thereto is made upon any such Security.
Any action taken by the Holders of the percentage in aggregate principal amount
of the Securities of any or all series, as the case may be, specified in this
Indenture in connection with such action shall be conclusively binding upon the
Issuer, the Trustee and the Holders of all the Securities affected by such
action.

                                    ARTICLE 7
                             SUPPLEMENTAL INDENTURES

      Section 7.01. Supplemental Indentures Without Consent of Securityholders.
The Issuer, when authorized by a resolution of its Board (which resolutions may
provide general authorization for such action and may provide that the specific
terms of such action may be determined by officers of the Issuer authorized
thereby), and the Trustee may from time to time and at any time enter into an
indenture or indentures supplemental hereto for one or more of the following
purposes:

      (a) to convey, transfer, assign, mortgage or pledge to the Trustee as
security for the Securities of one or more series any property or assets;

      (b) to evidence the succession of another legal entity to the Issuer, or
successive successions, and the assumption by the successor legal entity of the
covenants, agreements and obligations of the Issuer pursuant to Article 8;

      (c) to add to the covenants of the Issuer such further covenants,
restrictions, conditions or provisions as the Issuer and the Trustee shall
consider to be for the protection of the Holders of Securities, and to make the
occurrence, or the occurrence and continuance, of a default in any such
additional covenants, restrictions, conditions or provisions an Event of Default
permitting the enforcement of all or any of the several remedies provided in
this Indenture as herein set forth; provided, that in respect of any such
additional covenant, restriction, condition or provision 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 an Event of Default or may
limit the remedies available to the Trustee upon such an Event of Default or may
limit the right of the Holders of

                                       37
<PAGE>

a majority in aggregate principal amount of the Securities of such series to
waive such an Event of Default;

      (d) to cure any ambiguity or to correct or supplement any provision
contained herein or in any supplemental indenture which may be defective or
inconsistent with any other provision contained herein or in any supplemental
indenture; or to make such other provisions in regard to matters or questions
arising under this Indenture or under any supplemental indenture as the Board
may deem necessary or desirable and which shall not adversely affect the
interests of the Holders of the Securities in any material respect;

      (e) to establish the form or terms of Securities of any series as
permitted by Sections 2.01 and 2.03; and

      (f) 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 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, pursuant to the requirements of Section 5.10.

      The Trustee is hereby authorized to join with the Issuer in the execution
of any such supplemental indenture, to make any further appropriate agreements
and stipulations which may be therein contained and to accept the conveyance,
transfer, assignment, mortgage or pledge of any property thereunder, but the
Trustee shall not be obligated to enter into any such supplemental indenture
which affects the Trustee's own rights, duties or immunities under this
Indenture or otherwise.

      Any supplemental indenture authorized by the provisions of this section
may be executed without the consent of the Holders of any of the Securities at
the time outstanding, notwithstanding any of the provisions of Section 7.02.

      Section 7.02. Supplemental Indentures With Consent of Securityholders.
With the consent (evidenced as provided in Article 6) of the Holders of not less
than a majority in aggregate principal amount of the Securities at the time
Outstanding of all series affected by such supplemental indenture (voting as one
class), the Issuer, when authorized by a resolution of its Board (which
resolutions may provide general authorization for such action and may provide
that the specific terms of such action may be determined by officers of the
Issuer authorized thereby), and the Trustee may, from time to time and at any
time, enter into an indenture or indentures supplemental hereto for the purpose
of adding any provisions to or changing in any manner or eliminating any of the
provisions of this Indenture or of any supplemental indenture or of modifying in
any manner the rights of the Holders of the Securities of each such series;
provided, that no such supplemental indenture shall (a) (i) extend the final
maturity of any Security,

                                       38
<PAGE>

(ii) reduce the principal amount thereof, (iii) reduce the rate or extend the
time of payment of interest thereon, (iv) reduce any amount payable on
redemption thereof, (v) make the principal thereof (including any amount in
respect of original issue discount), or interest thereon payable in any coin or
currency other than that provided in the Securities or in accordance with the
terms thereof, (vi) modify or amend any provisions for converting any currency
into any other currency as provided in the Securities or in accordance with the
terms thereof, (vii) reduce the amount of the principal of an Original Issue
Discount Security that would be due and payable upon an acceleration of the
maturity thereof pursuant to Section 4.01 or the amount thereof provable in
bankruptcy pursuant to Section 4.02, (viii) modify or amend any provisions
relating to the conversion or exchange of the Securities for securities of the
Issuer or a guarantor of the Securities or of other entities or other property
(or the cash value thereof), including the determination of the amount of
securities or other property (or cash) into which the Securities shall be
converted or exchanged, other than as provided in the antidilution provisions or
other similar adjustment provisions of the Securities or otherwise in accordance
with the terms thereof, (ix) alter the provisions of Section 10.11 or Section
10.13 or impair or affect the right of any Securityholder to institute suit for
the payment thereof or, if the Securities provide therefor, any right of
repayment at the option of the Securityholder, in each case without the consent
of the Holder of each Security so affected, or (b) reduce the aforesaid
percentage of Securities of any series, the consent of the Holders of which is
required for any such supplemental indenture, without the consent of the Holders
of each Security so affected.

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

      Upon the request of the Issuer, accompanied by a copy of a resolution of
the Board (which resolutions may provide general authorization for such action
and may provide that the specific terms of such action may be determined by
officers of the Issuer authorized thereby) certified by the secretary or an
assistant secretary of the Issuer authorizing the execution of any such
supplemental indenture, and upon the filing with the Trustee of evidence of the
consent of Securityholders as aforesaid and other documents, if any, required by
Section 6.01, the Trustee shall join with the Issuer in the execution of such
supplemental indenture unless such supplemental indenture affects the Trustee's
own rights, duties or immunities under this Indenture or otherwise, in which
case the Trustee may in its discretion, but shall not be obligated to, enter
into such supplemental indenture.

                                       39
<PAGE>

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

      Promptly after the execution by the Issuer and the Trustee of any
supplemental indenture pursuant to the provisions of this Section, the Trustee
shall give notice thereof by (a) first class mail to the Holders of Securities
of each series affected thereby at their addresses as they shall appear on the
registry books of the Issuer or (b) by any other means set forth in such
supplemental indenture, setting forth in general terms the substance of such
supplemental indenture. Any failure of the Trustee to mail such notice, or any
defect therein, shall not, however, in any way impair or affect the validity of
any such supplemental indenture.

      Section 7.03. Effect of Supplemental Indenture. Upon the execution of any
supplemental indenture pursuant to the provisions hereof, this Indenture shall
be and be deemed to be modified and amended in accordance therewith and the
respective rights, limitations of rights, obligations, duties and immunities
under this Indenture of the Trustee, the Issuer and the Holders of Securities of
each series affected thereby shall thereafter be determined, exercised and
enforced hereunder subject in all respects to such modifications and amendments,
and all the terms and conditions of any such supplemental indenture shall be and
be deemed to be part of the terms and conditions of this Indenture for any and
all purposes.

      Section 7.04. Documents to Be Given to Trustee. The Trustee, subject to
the provisions of Sections 5.01 and 5.02, may receive an Officers' Certificate
and an Opinion of Counsel as conclusive evidence that any supplemental indenture
executed pursuant to this Article 7 complies with the applicable provisions of
this Indenture.

      Section 7.05. Notation On Securities In Respect Of Supplemental
Indentures. Securities of any series authenticated and delivered after the
execution of any supplemental indenture pursuant to the provisions of this
Article may bear a notation in form approved by the Trustee for such series as
to any matter provided for by such supplemental indenture or as to any action
taken by Securityholders. If the Issuer or the Trustee shall so determine, new
Securities of any series so modified as to conform, in the opinion of the
Trustee and the Board, to any modification of this Indenture contained in any
such supplemental indenture may be prepared by the Issuer, authenticated by the
Trustee and delivered in exchange for the Securities of such series then
Outstanding.

                    CONSOLIDATION, MERGER, SALE OR CONVEYANCE

      Section 8.01. Issuer May Consolidate, etc., on Certain Terms. The Issuer
covenants that it will not merge or consolidate with any other Person or sell or
convey all or substantially all of its assets to any Person, unless (i) either
the Issuer shall be the continuing legal entity, or the successor legal entity
or the Person which acquires by sale or conveyance substantially all the assets
of the Issuer (if other than the Issuer) shall expressly assume the due and
punctual payment of the principal of and interest on all the Securities,
according to their tenor, and the due and punctual performance and observance of
all of the covenants and conditions of this Indenture to be performed or
observed by the Issuer, by supplemental indenture satisfactory to the Trustee,
executed and delivered to the Trustee by such legal entity, and (ii) the Issuer
or such successor legal entity, as the case may be, shall not, immediately after
such merger or consolidation, or such sale or conveyance, be in default in the
performance of any such covenant or condition.

      Section 8.02. Successor Substituted. In case of any such consolidation,
merger, sale or conveyance, and following such an assumption by the successor
legal entity, such successor legal entity shall succeed to and be substituted
for the Issuer, with the same effect as if it had been named herein. Such
successor legal entity may cause to be signed, and may issue either in its own
name or in the name of the Issuer prior to such succession any or all of the
Securities issuable hereunder which theretofore shall not have been signed by
the Issuer and delivered to the Trustee; and, upon the order of such successor
legal entity instead of the Issuer 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 Issuer to the Trustee for authentication, and
any Securities which such successor legal entity thereafter shall cause to be
signed and delivered to the Trustee for that purpose. All of 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 phrasing and form (but not in substance) may be made in the
Securities thereafter to be issued as may be appropriate.

      In the event of any such sale or conveyance (other than a conveyance by
way of lease) the Issuer or any successor legal entity which shall theretofore
have become such in the manner described in this Article shall be discharged
from all obligations and covenants under this Indenture and the Securities and
may be liquidated and dissolved.

(i) the Issuer shall have paid or caused to be paid the principal of and
interest on all the Securities of any series outstanding hereunder (other than
Securities of such series which have been destroyed, lost or stolen and which
have been replaced or paid as provided in Section 2.09) as and when the same
shall have become due and payable, or (ii) the Issuer shall have delivered to
the Trustee for cancellation all Securities of any series theretofore
authenticated (other than any Securities of such series which shall have been
destroyed, lost or stolen and which shall have been replaced or paid as provided
in Section 2.09) or (iii) (A) all the securities of such series not theretofore
delivered to the Trustee for cancellation shall have become due and payable, or
are by their terms to become due and payable within one year or are to be called

for the giving of notice of redemption, and (B) the Issuer shall have
irrevocably deposited or caused to be deposited with the Trustee as trust funds
the entire amount in cash (other than moneys repaid by the Trustee or any paying
agent to the Issuer in accordance with Section 9.04) in the case of any series
of Securities the payments on which may only be made in United States dollars,
direct obligations of the United States of America, backed by its full faith and
credit ("U.S. Government Obligations"), maturing as to principal and interest at
such times and in such amounts as will insure the availability of cash, or a
combination thereof, sufficient to pay at maturity or upon redemption all
Securities of such series (other than any Securities of such series which shall
have been destroyed, lost or stolen and which shall have been replaced or paid
as provided in Section 2.09) not theretofore delivered to the Trustee for
cancellation, including principal and interest due or to become due on or prior
to such date of maturity as the case may be, and if, in any such case, the
Issuer shall also pay or cause to be paid all other sums payable hereunder by
the Issuer with respect to Securities of such series, then this Indenture shall
cease to be of further effect with respect to Securities of such series (except
as to (i) rights of registration of transfer and exchange of securities of such
series, and the Issuer's right of optional redemption, if any, (ii) substitution
of mutilated, defaced, destroyed, lost or stolen Securities, (iii) rights of
holders to receive payments of principal thereof and interest thereon upon the
original stated due

date therefor (but no upon acceleration), and remaining rights of the holders to
receive mandatory sinking fund payments, if any, (iv) the rights, obligations
and immunities of the Trustee hereunder and (v) the rights of the
Securityholders of such series as beneficiaries hereof with respect to the
property so deposited with the Trustee payable to all or any of them), and the
Trustee, on demand of the Issuer accompanied by an Officers' Certificate and an
Opinion of Counsel and at the cost and expense of the Issuer, shall execute
proper instruments acknowledging such satisfaction of and discharging this
Indenture with respect to such series; provided, that the rights of Holders of
the Securities to receive amounts in respect of principal of and interest on the
Securities held by them shall not be delayed longer than required by
then-applicable mandatory rules or policies of any securities exchange upon
which the Securities are listed. The Issuer agrees to reimburse the Trustee for
any costs or expenses thereafter reasonably and properly incurred and to
compensate the Trustee for any services thereafter reasonably and properly
rendered by the Trustee in connection with this Indenture or the Securities of
such series.

      (b) The following provisions shall apply to the Securities of each series
unless specifically otherwise provided in a Board Resolution, Officers'
Certificate or indenture supplemental hereto provided pursuant to Section 2.03.
In addition to discharge of the Indenture pursuant to the next preceding
paragraph, in the case of any series of Securities the exact amounts (including
the currency of payment) of principal of and interest due on which can be
determined at the time of making the deposit referred to in clause 9.01(b)(i)
below, the Issuer shall be deemed to have paid and discharged the entire
indebtedness on all the Securities of such a series on the 91st day after the
date of the deposit referred to in clause 9.01(b)(i) below, and the provisions
of this Indenture with respect to the Securities of such series thereto shall no
longer be in effect (except as to (1) rights of registration of transfer and
exchange of Securities of such series and the Issuer's right of optional
redemption, if any, (2) substitution of mutilated, defaced, destroyed, lost or
stolen Securities, (3) rights of Holders of Securities to receive payments of

duties and immunities of the Trustee hereunder, (5) the rights of the Holders of
Securities of such series as beneficiaries hereof with respect to the property
so deposited with the Trustee payable to all or any of them and (6) the
obligations of the Issuer under Section 3.02) and the Trustee, at the expense of
the Issuer and any guarantor of the Securities, shall at the Issuer's or such
guarantor's request, execute proper instruments acknowledging the same, if

            (i) with reference to this provision the Issuer or such guarantor
      has irrevocably deposited or caused to be irrevocably deposited with the
      Trustee as trust funds in trust, specifically pledged as security for, and
      dedicated solely to, the benefit of the Holders of the Securities of such

                                       43
<PAGE>

      series (A) cash in an amount, or (B) in the case of any series of
      Securities the payments on which may only be made in Dollars, U.S.
      Government Obligations, maturing as to principal and interest at such
      times and in such amounts as will insure the availability of cash or (C) a
      combination thereof, sufficient, in the opinion of a nationally recognized
      firm of independent public accountants expressed in a written
      certification thereof delivered to the Trustee, to pay (1) the principal
      and interest on all Securities of such series and Coupons appertaining
      thereto on each date that such principal or interest is due and payable
      and (2) any mandatory sinking fund payments on the dates on which such
      payments are due and payable in accordance with the terms of the Indenture
      and the Securities of such series;

            (ii) such deposit will not result in a breach or violation of, or
      constitute a default under, any agreement or instrument to which the
      Issuer is a party or by which it is bound;

            (iii) the Issuer or such guarantor has delivered to the Trustee an
      Opinion of Counsel based on the fact that (x) the Issuer has received
      from, or there has been published by, the Internal Revenue Service a
      ruling or (y) since the date hereof, there has been a change in the
      applicable Federal income tax law, in either case to the effect that, and
      such opinion shall confirm that, the Holders of the Securities of such
      series and Coupons appertaining thereto will not recognize income, gain or
      loss for Federal income tax purposes as a result of such deposit,
      defeasance and discharge and will be subject to Federal income tax on the
      same amount and in the same manner and at the same times, as would have
      been the case if such deposit, defeasance and discharge had not occurred;
      and

            (iv) the Issuer or such guarantor has delivered to the Trustee an
      Officers' Certificate or guarantor's Officers' Certificate and an Opinion
      of Counsel, each stating that all conditions precedent provided for
      relating to the defeasance contemplated by this provision have been
      complied with.

      (c) Each of the Issuer and any guarantor of the Securities shall be
released from its obligations under Section 8.01 with respect to the Securities
of any Series, Outstanding, and under any guarantee in respect thereof, on and
after the date the conditions set forth below are satisfied (hereinafter,
"covenant defeasance"). For this purpose, such covenant defeasance means that,
with respect to the Outstanding Securities of any Series, and under a guarantee
in respect thereof, the Issuer and any guarantor of the Securities may omit to
comply with and shall have no liability in respect of any term, condition or
limitation set forth in such Sections, whether directly or indirectly by reason
of any reference elsewhere herein to such Sections or by reason of any reference
in such Sections to any other provision herein or in any other document and such
omission to

                                       44
<PAGE>

comply shall not constitute an Event of Default under Section 4.01, but the
remainder of this Indenture and such Securities and Coupons and the Guarantee
shall be unaffected thereby. The following shall be the conditions to
application of this subsection (c) of this Section 9.01:

            (i) The Issuer or such guarantor has irrevocably deposited or caused
      to be deposited with the Trustee 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 the Securities of
      such series, (A) cash in an amount, or (B) in the case of any series of
      Securities the payments on which may only be made in Dollars, U.S.
      Government Obligations maturing as to principal and interest at such times
      and in such amounts as will insure the availability of cash or (C) a
      combination thereof, sufficient, in the opinion of a nationally recognized
      firm of independent public accountants expressed in a written
      certification thereof delivered to the Trustee, to pay (1) the principal
      and interest on all Securities of such series and Coupons appertaining
      thereto and (2) any mandatory sinking fund payments on the day on which
      such payments are due and payable in accordance with the terms of the
      Indenture and the Securities of such series.

            (ii) No Event of Default or event which with notice or lapse of time
      or both would become an Event of Default with respect to the Securities
      shall have occurred and be continuing on the date of such deposit or,
      insofar as subsections 4.01(c) and 4.01(d) 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).

            (iii) Such covenant defeasance shall not cause the Trustee to have a
      conflicting interest for purposes of the Trust Indenture Act of 1939 with
      respect to any securities of the Issuer.

            (iv) Such covenant defeasance shall not result in a breach or
      violation of, or constitute a default under, this Indenture or any other
      agreement or instrument to which the Issuer or such guarantor is a party
      or by which either of them is bound.

            (v) Such covenant defeasance shall not cause any Securities then
      listed on any registered national securities exchange under the Securities
      Exchange Act of 1934, as amended, to be delisted.

            (vi) The Issuer or such guarantor shall have delivered to the
      Trustee an Officers' Certificate or guarantor's Officers' Certificate, as
      the case may be, and Opinion of Counsel to the effect that the Holders of
      the

                                       45
<PAGE>

      Securities of such series 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.

            (vii) The Issuer or such guarantor shall have delivered to the
      Trustee an Officers' Certificate or guarantor's Officers' Certificate, as
      the case may be, and an Opinion of Counsel, each stating that all
      conditions precedent provided for relating to the covenant defeasance
      contemplated by this provision have been complied with.

      Section 9.02. Application by Trustee of Funds Deposited for Payment of
Securities. Subject to Section 9.04 and any subordination provisions applicable
to the Securities, all moneys deposited with the Trustee pursuant to Section
9.01 shall be held in trust and applied by it to the payment, either directly or
through any paying agent (including the Issuer acting as its own paying agent),
to the Holders of the particular Securities of such series for the payment or
redemption of which such moneys have been deposited with the Trustee, of all
sums due and to become due thereon for principal and interest; but such money
need not be segregated from other funds except to the extent required by law.

      Section 9.03. Repayment of Moneys Held by Paying Agent. In connection with
the satisfaction and discharge of this Indenture with respect to Securities of
any series, all moneys then held by any paying agent under the provisions of
this Indenture with respect to such series of Securities shall, upon demand of
the Issuer, be repaid to it or paid to the Trustee and thereupon such paying
agent shall be released from all further liability with respect to such moneys.

      Section 9.04. Return of Moneys Held by Trustee and Paying Agent Unclaimed
for Two Years. Any moneys deposited with or paid to the Trustee or any paying
agent for the payment of the principal of or interest on any Security of any
series and not applied but remaining unclaimed for two years after the date upon
which such principal or interest shall have become due and payable, shall, upon
the written request of the Issuer and unless otherwise required by mandatory
provisions of applicable escheat or abandoned or unclaimed property law, be
repaid to the Issuer by the Trustee for such series or such paying agent, and
the Holder of the Security of such series shall, unless otherwise required by
mandatory provisions of applicable escheat or abandoned or unclaimed property
laws, thereafter look only to the Issuer for any payment which such Holder may
be entitled to collect, and all liability of the Trustee or any paying agent
with respect to such moneys shall thereupon cease.

                            MISCELLANEOUS PROVISIONS

      Section 10.01. Incorporators, Stockholders, Members, Officers and
Directors of Issuer Exempt from Individual Liability. No recourse under or upon
any obligation, covenant or agreement contained in this Indenture, or in any
Security, or because of any indebtedness evidenced thereby, shall be had against
any incorporator, as such or against any past, present or future stockholder,
member, officer or director, as such, of the Issuer or of any successor, either
directly or through the Issuer 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 10.02. Provisions of Indenture for the Sole Benefit of Parties and
Securityholders. Nothing in this Indenture or in the Securities, expressed or
implied, shall give or be construed to give to any person, firm or corporation,
other than the parties hereto and their successors and the Holders of the
Securities, any legal or equitable right, remedy or claim under this Indenture
or under any covenant or provision herein contained, all such covenants and
provisions being for the sole benefit of the parties hereto and their successors
and of the Holders of the Securities.

      Section 10.03. Successors and Assigns of Issuer Bound by Indenture. All
the covenants, stipulations, promises and agreements in this Indenture contained
by or in behalf of the Issuer shall bind its successors and assigns, whether so
expressed or not.

      Section 10.04. Notices and Demands on Issuer, Trustee and Securityholders.
Any notice or demand which by any provision of this Indenture is required or
permitted to be given or served by the Trustee or by the Holders of Securities
to or on the Issuer may be given or served by being deposited postage prepaid,
first-class mail (except as otherwise specifically provided herein) addressed
(until another address of the Issuer is filed by the Issuer with the Trustee) to
ABN AMRO Bank N.V. at the following address:

      ABN AMRO Bank N.V.

      Any notice, direction, request or demand by the Issuer or any
Securityholder to or upon the Trustee shall be deemed to have been sufficiently
given or made, for all purposes, if given or made to its Corporate Trust Office
at [__].

      Where this Indenture provides for notice to Holders, such notice shall be
sufficiently given (unless otherwise herein expressly provided) if in writing
and mailed, first-class postage prepaid, to each Holder entitled thereto, at his
last address as it appears in the Security register. In any case where notice to
Holders is given by mail, neither the failure to mail such notice, nor any
defect in any notice so mailed, to any particular Holder shall affect the
sufficiency of such notice with respect to other Holders. Where this Indenture
provides for notice in any manner, such notice may be waived in writing by the
person entitled to receive such notice, either before or after the event, and
such waiver shall be the equivalent of such notice. Waivers of notice by Holders
shall be filed with the Trustee, but such filing shall not be a condition
precedent to the validity of any action taken in reliance upon such waiver.

      In case, by reason of the suspension of or irregularities in regular mail
service, it shall be impracticable to mail notice to the Issuer and
Securityholders when such notice is required to be given pursuant to any
provision of this Indenture, then any manner of giving such notice as shall be
satisfactory to the Trustee shall be deemed to be a sufficient giving of such
notice.

      Section 10.05. Officers' Certificates and Opinions of Counsel; Statements
to be Contained Therein. Upon any application or demand by the Issuer to the
Trustee to take any action under any of the provisions of this Indenture, the
Issuer shall furnish to the Trustee an Officers' Certificate stating that all
conditions precedent provided for in this Indenture relating to the proposed
action have been complied with and an Opinion of Counsel stating that in the
opinion of such counsel all such conditions precedent have been complied with,
except that in the case of any such application or demand as to which the
furnishing of such documents is specifically required by any provision of this
Indenture relating to such particular application or demand, no additional
certificate or opinion need be furnished.

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

                                       48
<PAGE>

statement as to whether or not, in the opinion of such person, such condition or
covenant has been complied with.

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

      Any certificate, statement or opinion of an officer of the Issuer or of
counsel may be based, insofar as it relates to accounting matters, upon a
certificate or opinion of or representations by an accountant or firm of
accountants in the employ of the Issuer, unless such officer or counsel, as the
case may be, knows that the certificate or opinion or representations with
respect to the accounting matters upon which his certificate, statement or
opinion may be based as aforesaid are erroneous, or in the exercise of
reasonable care should know that the same are erroneous.

      Any certificate or opinion of any independent firm of public accountants
filed with the Trustee shall contain a statement that such firm is independent.

      Section 10.06. Payments Due on Saturdays, Sundays and Holidays. If the
date of maturity of interest on or principal of the Securities of any series or
the date fixed for redemption or repayment of any such Security shall not be a
Business Day, then payment of interest or principal need not be made on such
date, but may be made on the next succeeding Business Day with the same force
and effect as if made on the date of maturity or the date fixed for redemption,
and no interest shall accrue for the period after such date.

      Section 10.07. Conflict of any Provision of Indenture with Trust Indenture
Act of 1939. If and to the extent that any provision of this Indenture limits,
qualifies or conflicts with another provision included in this Indenture by
operation of Sections 310 to 317, inclusive, of the Trust Indenture Act of 1939
(an "incorporated provision"), such incorporated provision shall control.

      Section 10.08. New York Law to Govern. This Indenture and each Security
shall be deemed to be a contract under the laws of the State of New

                                       49
<PAGE>

York, and for all purposes shall be construed in accordance with the laws of
such State, except as may otherwise be required by mandatory provisions of law.

      Section 10.09. Counterparts. This Indenture may be executed in any number
of counterparts, each of which shall be an original; but such counterparts shall
together constitute but one and the same instrument.

      Section 10.10. Effect of Headings. The Article and Section headings herein
and the Table of Contents are for convenience only and shall not affect the
construction hereof.

      Section 10.11. Securities in a Non-U.S. Currency. Unless otherwise
specified in an Officers' Certificate delivered pursuant to Section 2.03 of this
Indenture with respect to a particular series of Securities, whenever for
purposes of this Indenture any action may be taken by the Holders of a specified
percentage in aggregate principal amount of Securities of all series or all
series affected by a particular action at the time Outstanding and, at such
time, there are Outstanding Securities of any series which are denominated in a
coin or currency other than Dollars, then the principal amount of Securities of
such series which shall be deemed to be Outstanding for the purpose of taking
such action shall be that amount of Dollars that could be obtained for such
amount at the Market Exchange Rate. For purposes of this Section 10.11, Market
Exchange Rate shall mean the noon Dollar buying rate in New York City for cable
transfers of that currency as published by the Federal Reserve Bank of New York.
If such Market Exchange Rate is not available for any reason with respect to
such currency, the Trustee shall use, in its sole discretion and without
liability on its part, such quotation of the Federal Reserve Bank of New York as
of the most recent available date, or quotations from one or more major banks in
The City of New York or in the country of issue of the currency in question, or
such other quotations as the Trustee shall deem appropriate. The provisions of
this paragraph shall apply in determining the equivalent principal amount in
respect of Securities of a series denominated in a currency other than Dollars
in connection with any action taken by Holders of Securities pursuant to the
terms of this Indenture.

      All decisions and determinations of the Trustee regarding the Market
Exchange Rate or any alternative determination provided for in the preceding
paragraph shall be in its sole discretion and shall, in the absence of manifest
error, be conclusive to the extent permitted by law for all purposes and
irrevocably binding upon the Issuer and all Holders.

      Section 10.12. Submission to Jurisdiction. The Issuer agrees that any
legal suit, action or proceeding arising out of or based upon this Indenture may
be instituted in any State or Federal court in the Borough of Manhattan, City
and State of New York, and, to the fullest extent permitted by law, waives any
objection which it may now or hereafter have to the laying of venue of any such

                                       50
<PAGE>

proceeding, and irrevocably submits to the jurisdiction of such court in any
suit, action or proceeding. The Issuer has appointed [Willie J. Miller, Jr.,
Esq., Chief Legal Officer and Executive Vice President], ABN AMRO North America,
Inc., as its authorized agent (the "Authorized Agent") upon which process may be
instituted in any State or Federal court in the Borough of Manhattan, City and
State of New York and the Issuer expressly accepts the jurisdiction of any such
court in respect of such action. Such appointment shall be irrevocable unless
and until a successor authorized agent, located or with an office in the Borough
of Manhattan, City and State of New York, shall have been appointed by the
Issuer and such appointment shall have been accepted by such successor
authorized agent. The Issuer represents and warrants that the Authorized Agent
has agreed to act as said agent for service of process, and the Issuer agrees to
take any and all action, including the filing of any and all documents and
instruments, that may be necessary to continue such appointment in full force
and effect as aforesaid. Service of process upon the Authorized Agent and
written notice of such service to the Issuer shall be deemed, in every respect,
effective service of process upon the Issuer.

      Section 10.13. Judgment Currency. The Issuer agrees, to the fullest extent
that it may effectively do so under applicable law, that (a) if for the purpose
of obtaining judgment in any court it is necessary to convert the sum due in
respect of the principal of or interest on the Securities of any series (the
"Required Currency") into a currency in which a judgment will be rendered (the
"Judgment Currency"), the rate of exchange used shall be the rate at which in
accordance with normal banking procedures the Trustee could purchase in The City
of New York the Required Currency with the Judgment Currency on the day on which
final unappealable judgment is entered, unless such day is not a New York
Banking Day, then, to the extent permitted by applicable law, the rate of
exchange used shall be the rate at which in accordance with normal banking
procedures the Trustee could purchase in The City of New York the Required
Currency with the Judgment Currency on the New York Banking Day preceding the
day on which final unappealable judgment is entered and (b) its obligations
under this Indenture to make payments in the Required Currency (i) shall not be
discharged or satisfied by any tender, or any recovery pursuant to any judgment
(whether or not entered in accordance with subsection (a)), in any currency
other than the Required Currency, except to the extent that such tender or
recovery shall result in the actual receipt, by the payee, of the full amount of
the Required Currency expressed to be payable in respect of such payments, (ii)
shall be enforceable as an alternative or additional cause of action for the
purpose of recovering in the Required Currency the amount, if any, by which such
actual receipt shall fall short of the full amount of the Required Currency so
expressed to be payable and (iii) shall not be affected by judgment being
obtained for any other sum due under this Indenture. For purposes of the
foregoing, "New York Banking Day" means any day except a Saturday, Sunday or a
legal holiday in

                                       51
<PAGE>

The City of New York or a day on which banking institutions in The City of New
York are authorized or required by law or executive order to close

                   REDEMPTION OF SECURITIES AND SINKING FUNDS

      Section 11.01. Applicability Of Article. The provisions of this Article
shall be applicable to the Securities of any series which are redeemable before
their maturity or to any sinking fund for the retirement of Securities of a
series except as otherwise specified as contemplated by Section 2.03 for
Securities of such series.

      Section 11.02. Notice Of Redemption; Partial Redemptions. Notice of
redemption to the Holders of Securities of any series to be redeemed as a whole
or in part at the option of the Issuer shall be given by mailing notice of such
redemption by first class mail, postage prepaid, at least 30 days and not more
than 60 days prior to the date fixed for redemption to such Holders of
Securities of such series at their last addresses as they shall appear upon the
registry books. Any notice which is mailed in the manner herein provided shall
be conclusively presumed to have been duly given, whether or not the Holder
receives the notice. Failure to give notice by mail, or any defect in the notice
to the Holder of any Security of a series designated for redemption as a whole
or in part shall not affect the validity of the proceedings for the redemption
of any other Security of such series.

      The notice of redemption to each such Holder shall specify the principal
amount of each Security of such series held by such Holder to be redeemed, the
date fixed for redemption, the redemption price, the place or places of payment,
that payment will be made upon presentation and surrender of such Securities,
that such redemption is pursuant to the mandatory or optional sinking fund, or
both, if such be the case, that interest accrued to the date fixed for
redemption will be paid as specified in such notice and that on and after said
date interest thereon or on the portions thereof to be redeemed will cease to
accrue. In case any Security of a series is to be redeemed in part only the
notice of redemption shall state the portion of the principal amount thereof to
be redeemed and shall state that on and after the date fixed for redemption,
upon surrender of such Security, a new Security or Securities of such series in
principal amount equal to the unredeemed portion thereof will be issued.

      The notice of redemption of Securities of any series to be redeemed at the
option of the Issuer shall be given by the Issuer or, at the Issuer's request,
by the Trustee in the name and at the expense of the Issuer.

      On or before the redemption date specified in the notice of redemption
given as provided in this Section, the Issuer will deposit with the Trustee or
with one or more paying agents (or, if the Issuer is acting as its own paying
agent, set aside, segregate and hold in trust as provided in Section 3.04) an
amount of money or other property sufficient to redeem on the redemption date
all the Securities of such series so called for redemption at the appropriate
redemption price, together with accrued interest to the date fixed for
redemption. If less than all the outstanding Securities of a series are to be
redeemed, the Issuer will deliver to the Trustee at least 70 days prior to the
date fixed for redemption an Officers' Certificate stating the aggregate
principal amount of Securities to be redeemed.

      If less than all the Securities of a series are to be redeemed, the
Trustee shall select, in such manner as it shall deem appropriate and fair,
Securities of such Series to be redeemed in whole or in part. Securities may be
redeemed in part in multiples equal to the minimum authorized denomination for
Securities of such series or any multiple thereof. The Trustee shall promptly
notify the Issuer in writing of the Securities of such series selected for
redemption and, in the case of any Securities of such series 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 of any series 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 11.03. Payment of Securities Called for Redemption. If notice of
redemption has been given as above provided, the Securities or portions of
Securities specified in such notice shall become due and payable on the date and
at the place stated in such notice at the applicable redemption price, together
with interest accrued to the date fixed for redemption, and on and after said
date (unless the Issuer shall default in the payment of such Securities at the
redemption price, together with interest accrued to said date) interest on the
Securities or portions of Securities so called for redemption shall cease to
accrue and, except as provided in Sections 5.05 and 9.04, such Securities shall
cease from and after the date fixed for redemption to be entitled to any benefit
or security under this Indenture, and the Holders thereof shall have no right in
respect of such Securities except the right to receive the redemption price
thereof and unpaid interest to the date fixed for redemption. On presentation
and surrender of such Securities at a place of payment specified in said notice,
said Securities or the specified portions thereof shall be paid and redeemed by
the Issuer at the applicable redemption price, together with interest accrued
thereon to the date fixed for redemption; provided that any semiannual payment
of interest becoming due on the date fixed for redemption shall be payable to
the Holders of such Securities registered as such on the relevant record date
subject to the terms and provisions of Sections 2.03 and 2.04 hereof.

                                       53
<PAGE>

      If any Security called for redemption shall not be so paid upon surrender
thereof for redemption, the principal shall, until paid or duly provided for,
bear interest from the date fixed for redemption at the rate of interest or
Yield to Maturity (in the case of an Original Issue Discount Security) borne by
such Security.

      Upon presentation of any Security redeemed in part only, the Issuer shall
execute and the Trustee shall authenticate and deliver to or on the order of the
Holder thereof, at the expense of the Issuer, a new Security or Securities of
such series , of authorized denominations, in principal amount equal to the
unredeemed portion of the Security so presented.

      Section 11.04. Exclusion of Certain Securities from Eligibility for
Selection for Redemption. Securities shall be excluded from eligibility for
selection for redemption if they are identified by registration and certificate
number in a written statement signed by an authorized officer of the Issuer and
delivered to the Trustee at least 40 days prior to the last date on which notice
of redemption may be given as being owned of record and beneficially by, and not
pledged or hypothecated by either (a) the Issuer or (b) an entity specifically
identified in such written statement as directly or indirectly controlling or
controlled by or under direct or indirect common control with the Issuer.

      Section 11.05. Mandatory and Optional Sinking Funds. The minimum amount of
any sinking fund payment provided for by the terms of the 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 Securities
of any series is herein referred to as an "optional sinking fund payment". The
date on which a sinking fund payment is to be made is herein referred to as the
"sinking fund payment date".

      In lieu of making all or any part of any mandatory sinking fund payment
with respect to any series of Securities in cash, the Issuer may at its option
(a) deliver to the Trustee Securities of such series theretofore purchased or
otherwise acquired (except upon redemption pursuant to the mandatory sinking
fund) by the Issuer or receive credit for Securities of such series (not
previously so credited) theretofore purchased or otherwise acquired (except as
aforesaid) by the Issuer and delivered to the Trustee for cancellation pursuant
to Section 2.07, (b) receive credit for optional sinking fund payments (not
previously so credited) made pursuant to this Section, or (c) receive credit for
Securities of such series (not previously so credited) redeemed by the Issuer
through any optional redemption provision contained in the terms of such series.
Securities so delivered or credited shall be received or credited by the Trustee
at the sinking fund redemption price specified in such Securities.

                                       54
<PAGE>

      On or before the sixtieth day next preceding each sinking fund payment
date for any series, the Issuer will deliver to the Trustee a written statement
(which need not contain the statements required by Section 10.05) signed by an
authorized officer of the Issuer (a) specifying the portion of the mandatory
sinking fund payment to be satisfied by payment of cash and the portion to be
satisfied by credit of Securities of such series, (b) stating that none of the
Securities of such series has theretofore been so credited, (c) stating that no
defaults in the payment of interest or Events of Default with respect to such
series have occurred (which have not been waived or cured) and are continuing
and (d) stating whether or not the Issuer intends to exercise its right to make
an optional sinking fund payment with respect to such series and, if so,
specifying the amount of such optional sinking fund payment which the Issuer
intends to pay on or before the next succeeding sinking fund payment date. Any
Securities of such series to be credited and required to be delivered to the
Trustee in order for the Issuer to be entitled to credit therefor as aforesaid
which have not theretofore been delivered to the Trustee shall be delivered for
cancellation pursuant to Section 2.10 to the Trustee with such written statement
(or reasonably promptly thereafter if acceptable to the Trustee). Such written
statement shall be irrevocable and upon its receipt by the Trustee the Issuer
shall become unconditionally obligated to make all the cash payments or payments
therein referred to, if any, on or before the next succeeding sinking fund
payment date. Failure of the Issuer, on or before any such sixtieth day, to
deliver such written statement and Securities specified in this paragraph, if
any, shall not constitute a default but shall constitute, on and as of such
date, the irrevocable election of the Issuer (i) that the mandatory sinking fund
payment for such series due on the next succeeding sinking fund payment date
shall be paid entirely in cash without the option to deliver or credit
Securities of such series in respect thereof and (ii) that the Issuer will make
no optional sinking fund payment with respect to such series as provided in this
Section.

      If the sinking fund payment or payments (mandatory or optional or both) to
be made in cash on the next succeeding sinking fund payment date plus any unused
balance of any preceding sinking fund payments made in cash shall exceed $50,000
(or a lesser sum if the Issuer shall so request) with respect to the Securities
of any particular series, such cash shall be applied on the next succeeding
sinking fund payment date to the redemption of Securities of such series at the
sinking fund redemption price together with accrued interest to the date fixed
for redemption. If such amount shall be $50,000 or less and the Issuer makes no
such request then it shall be carried over until a sum in excess of $50,000 is
available. The Trustee shall select, in the manner provided in Section 11.02,
for redemption on such sinking fund payment date a sufficient principal amount
of Securities of such series to absorb said cash, as nearly as may be, and shall
(if requested in writing by the Issuer) inform the Issuer of the serial numbers
of the Securities of such series (or portions thereof) so selected. Securities
of any series which are (a) owned by the Issuer or an entity known by the
Trustee to be

                                       55
<PAGE>

directly or indirectly controlling or controlled by or under direct or indirect
common control with the Issuer, as shown by the Security register, and not known
to the Trustee to have been pledged or hypothecated by the Issuer or any such
entity or (b) identified in an Officers' Certificate at least 60 days prior to
the sinking fund payment date as being beneficially owned by, and not pledged or
hypothecated by, the Issuer or an entity directly or indirectly controlling or
controlled by or under direct or indirect common control with the Issuer shall
be excluded from Securities of such series eligible for selection for
redemption. The Trustee, in the name and at the expense of the Issuer (or the
Issuer, if it shall so request the Trustee in writing) shall cause notice of
redemption of the Securities of such series to be given in substantially the
manner provided in Section 11.02 (and with the effect provided in Section 11.03)
for the redemption of Securities of such series in part at the option of the
Issuer. The amount of any sinking fund payments not so applied or allocated to
the redemption of Securities of such series shall be added to the next cash
sinking fund payment for such series and, together with such payment, shall be
applied in accordance with the provisions of this Section. Any and all sinking
fund moneys held on the stated maturity date of the Securities of any particular
series (or earlier, if such maturity is accelerated), which are not held for the
payment or redemption of particular Securities of such series shall be applied,
together with other moneys, if necessary, sufficient for the purpose, to the
payment of the principal of, and interest on, the Securities of such series at
maturity.

      On or before each sinking fund payment date, the Issuer shall pay to the
Trustee in cash or shall otherwise provide for the payment of all interest
accrued to the date fixed for redemption on Securities to be redeemed on the
next following sinking fund payment date.

      The Trustee shall not redeem or cause to be redeemed any Securities of a
series with sinking fund moneys or give any notice of redemption of Securities
for such series by operation of the sinking fund during the continuance of a
default in payment of interest on such Securities or of any Event of Default
except that, where the mailing of notice of redemption of any Securities shall
theretofore have been made, the Trustee shall redeem or cause to be redeemed
such Securities, provided that it shall have received from the Issuer a sum
sufficient for such redemption. Except as aforesaid, any moneys in the sinking
fund for such series at the time when any such default or Event of Default shall
occur, and any moneys thereafter paid into the sinking fund, shall, during the
continuance of such default or Event of Default, be deemed to have been
collected under Article 4 and held for the payment of all such Securities. In
case such Event of Default shall have been waived as provided in Section 4.09 or
the default cured on or before the sixtieth day preceding the sinking fund
payment date in any year, such moneys shall thereafter be applied on the next
succeeding sinking fund payment date in accordance with this Section to the
redemption of such Securities.
