               (20) if the  Securities of the series shall be issued in whole or
in part in global  form,  (A) the  Depositary  for such Global  Securities,  (B)
whether beneficial owners of interests in any Securities of the series in global
form may exchange such interests for certificated  Securities of such series, to
be registered in the names of or to be held by such  beneficial  owners or their
nominees and to be of like tenor of any authorized  form and  denomination,  and
(C) if other than as provided in Section 2.08, the circumstances under which any
such exchange may occur;

               (21) the designation of the Depositary;

               (22) any restrictions on the  registration,  transfer or exchange
of the Securities;

               (23) if the  Securities  of the series may be issued or delivered
(whether upon original issuance or upon exchange of a temporary Security of such

                                       9

series or  otherwise),  or any  installment of principal or interest is payable,
only upon receipt of certain  certificates or other documents or satisfaction of
other conditions in addition to those specified in this Indenture,  the form and
terms of such certificates, documents or conditions;

               (24) the terms and conditions of any right to convert or exchange
Securities  of the  series  into or for  other  securities  or  property  of the
Company;

               (25)  whether the  Securities  are secured or  unsecured,  and if
secured,  the security and related terms in connection therewith (which shall be
provided  for  in  a  separate  security   agreement  and/or  other  appropriate
documentation); and

               (26) any other  terms of the  series  (which  terms  shall not be
inconsistent  with the provisions of this  Indenture)  including any terms which
may be required by or  advisable  under  United  States laws or  regulations  or
advisable (as  determined  by the Company) in  connection  with the marketing of
Securities of the series.

         (c) All Securities of any one series shall be  substantially  identical
except as to denomination and except as may otherwise be provided (i) by a Board
Resolution,  (ii) by action taken pursuant to a Board  Resolution and set forth,
or determined in the manner provided,  in the related  Officers'  Certificate or
(iii) in an indenture supplemental hereto. All Securities of any one series need
not be issued at the same time and, unless otherwise  provided,  a series may be
reopened,  without the  consent of the  Holders,  for  issuances  of  additional
Securities of such series.

         (d) If any of the terms of the Securities of any series are established
by action taken pursuant to a Board Resolution,  a copy of such Board Resolution
shall be delivered  to the Trustee at or prior to the delivery of the  Officers'
Certificate setting forth, or providing the manner for determining, the terms of
the  Securities of such series,  and an  appropriate  record of any action taken
pursuant  thereto in  connection  with the  issuance of any  Securities  of such
series  shall  be  delivered  to the  Trustee  prior to the  authentication  and
delivery thereof.

SECTION 2.03.     DENOMINATIONS.

                  Unless  otherwise  provided as  contemplated  by Section 2.02,
Securities of a series denominated in Dollars shall be issuable in denominations
of U.S. $1,000 and any integral  multiple thereof.  Securities  denominated in a
foreign currency shall be issuable in such denominations as are established with
respect to such Securities in or pursuant to this Indenture.

SECTION 2.04.     EXECUTION AND AUTHENTICATION.

                  An Officer shall sign the Securities for the Company by manual
or facsimile signature.

                  If an Officer whose signature is on a Security no longer holds
that  office  at the  time a  Security  is  authenticated,  the  Security  shall
nevertheless be valid.

                                       10

<page>

                  A  Security  shall  not be valid  until  authenticated  by the
manual signature of the Trustee. The signature shall be conclusive evidence that
the Security has been authenticated under this Indenture.

                  The Trustee shall,  upon a written order of the Company signed
by  an  Officer  (an  "AUTHENTICATION   ORDER"),   together  with  an  Officers'
Certificate  and an Opinion of Counsel,  authenticate  Securities  for  original
issue in the aggregate principal amount stated in the Authentication Order.

                  The Trustee may appoint an authenticating  agent acceptable to
the Company to authenticate Securities. An authenticating agent may authenticate
Securities  whenever the Trustee may do so. Each  reference in this Indenture to
authentication  by  the  Trustee  includes  authentication  by  such  agent.  An
authenticating  agent has the same rights as an Agent to deal with Holders or an
Affiliate of the Company.

                  Notwithstanding the foregoing, if any Security shall have been
authenticated and delivered  hereunder but never issued and sold by the Company,
and the Company shall deliver such Security to the Trustee for  cancellation  as
provided in Section 2.13  together  with a written  statement  stating that such
Security has never been issued and sold by the Company, for all purposes of this
Indenture  such Security  shall be deemed never to have been  authenticated  and
delivered hereunder and shall not be entitled to the benefits of this Indenture.

SECTION 2.05.     REGISTRAR AND PAYING AGENT; APPOINTMENT OF DEPOSITARY.

                  The  Company   shall   maintain  an  office  or  agency  where
Securities  may be  presented  for  registration  of  transfer  or for  exchange
("REGISTRAR")  and an office or agency where  Securities  may be  presented  for
payment ("PAYING AGENT").  The Registrar shall keep a register of the Securities
and of  their  transfer  and  exchange.  The  Company  may  appoint  one or more
co-registrars  and one or more additional  paying agents.  The term  "REGISTRAR"
includes any  co-registrar  and the term "PAYING AGENT"  includes any additional
paying  agent.  The Company  may change any Paying  Agent or  Registrar  without
notice to any Holder.  The Company shall promptly  notify the Trustee in writing
of the name and  address  of any  Agent  not a party to this  Indenture.  If the
Company  fails to appoint or  maintain  another  entity as  Registrar  or Paying
Agent, the Trustee shall act as such. The Company or any of its Subsidiaries may
act as Paying Agent or Registrar.

                  The Company initially appoints The Depository Trust Company to
act as Depositary with respect to the Global Securities.

                  The  Company  initially  appoints  the  Trustee  to act as the
Registrar  and  Paying  Agent  with  respect  to  the  Securities  and to act as
Custodian with respect to the Global Securities.

SECTION 2.06.     PAYING AGENT TO HOLD MONEY IN TRUST.

                  The Company  shall  require  each Paying  Agent other than the
Trustee  to agree in writing  that the  Paying  Agent will hold in trust for the
benefit  of Holders or the  Trustee  all money held by the Paying  Agent for the
payment of principal, premium or interest on the Securities or other payments in

                                       11

<page>

respect of the  Securities  or otherwise  held by it as Paying  Agent,  and will
notify the Trustee of any default by the Company in making any such payment when
due. While any such default continues, the Trustee may require a Paying Agent to
pay all money held by it to the  Trustee.  The Company at any time may require a
Paying  Agent to pay all money held by it to the  Trustee.  Upon payment over to
the Trustee,  the Paying Agent (if other than the Company or a Subsidiary) shall
have no further  liability for the money. If the Company or a Subsidiary acts as
Paying  Agent,  it shall  segregate  and hold in a  separate  trust fund for the
benefit of the Holders all money held by it as Paying Agent. Upon any bankruptcy
or reorganization  proceedings  relating to the Company, the Trustee shall serve
as Paying Agent for the Securities.

SECTION 2.07.     HOLDER LISTS.

                  The  Trustee  shall  preserve  in  as  current  a  form  as is
reasonably  practicable  the most recent list  available  to it of the names and
addresses of all Holders and shall otherwise  comply with TIA ss.312(a).  If the
Trustee is not the Registrar,  the Company shall furnish to the Trustee at least
seven Business Days before each Interest Payment Date and at such other times as
the Trustee  may request in writing,  a list in such form and as of such date as
the Trustee may reasonably  require of the names and addresses of the Holders of
Securities, and the Company shall otherwise comply with TIA ss.312(a).

SECTION 2.08.     TRANSFER AND EXCHANGE.

         (a) Upon  surrender for  registration  of transfer of any  certificated
Security  of any series at the office or agency  maintained  pursuant to Section
4.02 in a place of payment for that series,  the Company shall execute,  and the
Trustee shall authenticate and deliver, in the name of the designated transferee
or transferees,  one or more new certificated  Securities of the same series, of
any authorized  denominations and of a same aggregate  principal amount and like
tenor and containing identical terms and provisions.

         (b) At the option of the  Holder,  Securities  of any series  (except a
Security  in global  form) may be  exchanged  for other  Securities  of the same
series, of any authorized  denominations,  of a same aggregate  principal amount
and like tenor and containing identical terms and provisions,  upon surrender of
the Securities to be exchanged at such office or agency. Whenever any Securities
are so  surrendered  for exchange,  the Company shall  execute,  and the Trustee
shall  authenticate  and deliver,  the  Securities  which the Holder  making the
exchange is entitled to receive.

         (c)  Notwithstanding  any other  provision of this Section,  unless and
until it is exchanged in whole or in part for Securities in certificated form, a
Security in global form  representing  all or a portion of the  Securities  of a
series  may not be  transferred  except  as a whole by the  Depositary  for such
series to a nominee of such  Depositary  or by a nominee of such  Depositary  to
such  Depositary or another  nominee of such Depositary or by such Depositary or
any such nominee to a successor  Depositary for such series or a nominee of such
successor Depositary.

         (d) If at any  time  the  Depositary  for the  Securities  of a  series
notifies the Company  that it is  unwilling or unable to continue as  Depositary
for the  Securities  of such  series  or if at any time the  Depositary  for the

                                       12

<page>

Securities of such series shall no longer be registered  and in good standing as
a clearing  agency under the Exchange Act, the Company shall appoint a successor
Depositary  with  respect  to the  Securities  of such  series.  If a  successor
Depositary  for the  Securities  of such series is not  appointed by the Company
prior to the  resignation  of the Depositary  and, in any event,  within 90 days
after the Company  receives such notice or becomes aware of such  ineligibility,
the Company's  designation  of the  Depositary  pursuant to Section  2.02(b)(21)
shall no longer be effective  with respect to the  Securities of such series and
the Company shall execute,  and the Trustee,  upon receipt of an  Authentication
Order for the  authentication  and delivery of  certificated  Securities of such
series of like tenor, shall authenticate and deliver,  Securities of such series
of like  tenor in  certificated  form,  in  authorized  denominations  and in an
aggregate  principal  amount  equal to the  principal  amount of the Security or
Securities  of such  series of like tenor in global  form in  exchange  for such
Security or Securities in global form.

         (e) The Company may at any time in its sole  discretion  determine that
all (but not less than all)  Securities  of a series issued in global form shall
no longer be  represented  by such a Security or  Securities  in global form. In
such event the  Company  shall  execute,  and the  Trustee,  upon  receipt of an
Authentication  Order  for  the  authentication  and  delivery  of  certificated
Securities  of such  series  of like  tenor,  shall  authenticate  and  deliver,
Securities  of such series of like tenor in  certificated  form,  in  authorized
denominations and in an aggregate principal amount equal to the principal amount
of the  Security  or  Securities  of such series of like tenor in global form in
exchange for such Security or Securities in global form.

         (f) If specified  by the Company  pursuant to Section 2.02 with respect
to a series of  Securities,  the  Depositary  for such  series may  surrender  a
Security  in  global  form of such  series in  exchange  in whole or in part for
Securities of such series in  certificated  form on such terms as are acceptable
to the Company and such Depositary.  Thereupon,  the Company shall execute,  and
the Trustee shall authenticate and deliver, without service charge,

                  (i)   to  each  Person  specified  by  such  depositary  a new
                        certificated  Security or  Securities of the same series
                        of  like  tenor,  of  any  authorized   denomination  as
                        requested by such Person in aggregate  principal  amount
                        equal to and in exchange  for such  Person's  beneficial
                        interest in the Security in global form;

                        and

                  (ii)  to such Depositary a new Security in global form of like
                        tenor in a denomination equal to the difference, if any,
                        between the principal amount of the surrendered Security
                        in global  form and the  aggregate  principal  amount of
                        certificated Securities delivered to Holders thereof.

         (g) Upon the  exchange of a Security in global form for  Securities  in
certificated  form,  such  Security  in global  form  shall be  canceled  by the
Trustee.  Securities in  certificated  form issued in exchange for a Security in
global form  pursuant to this Section  shall be  registered in such names and in
such  authorized  denominations  as the  Depositary  for such Security in global
form,  pursuant  to  instructions  from its direct or Indirect  Participants  or
otherwise, shall instruct the Trustee in writing. The Trustee shall deliver such
Securities to the Persons in whose names such Securities are so registered.

                                       13

<page>

         (h) Whenever any Securities are surrendered  for exchange,  the Company
shall execute,  and the Trustee shall  authenticate and deliver,  the Securities
which the Holder making the exchange is entitled to receive.

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

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

         (k) No service charge shall be made for any registration of transfer or
for any  exchange of  Securities,  but the Company may require  payment of a sum
sufficient to cover any tax or other governmental  charge that may be imposed in
connection with any  registration  or transfer or exchange of Securities,  other
than exchanges pursuant to Section 2.12 or 3.06 not involving any transfer.

         (l) The  Company  shall  not be  required  (i) to issue,  register  the
transfer of, or exchange any Securities for a period beginning at the opening of
business 15 days before any selection for redemption of Securities of like tenor
and of the  series of which such  Security  is a part and ending at the close of
business on the earliest  date on which the  relevant  notice of  redemption  is
deemed to have been given to all Holders of Securities of like tenor and of such
series to be  redeemed;  or (ii) to register  the  transfer  of or exchange  any
Security so selected for redemption,  in whole or in part, except the unredeemed
portion of any Security being redeemed in part.

         (m) The foregoing  provisions  relating to  registration,  transfer and
exchange may be modified,  supplemented or superseded with respect to any series
of Securities by a Board  Resolution or in one or more  indentures  supplemental
hereto.

         (n) The  following  legend  shall  appear  on the  face  of all  Global
Securities unless specifically  stated otherwise in the applicable  provision of
this Indenture:

         "THIS  GLOBAL  SECURITY  IS HELD BY THE  DEPOSITARY  (AS DEFINED IN THE
         INDENTURE  GOVERNING  THIS  SECURITY) OR ITS NOMINEE IN CUSTODY FOR THE
         BENEFIT OF THE BENEFICIAL  OWNERS HEREOF,  AND,  UNLESS AND UNTIL IT IS
         EXCHANGED  FOR  SECURITIES IN  DEFINITIVE  FORM IN ACCORDANCE  WITH THE
         INDENTURE,  (I) IS NOT TRANSFERABLE EXCEPT AS A WHOLE BY THE DEPOSITARY
         TO A NOMINEE OF THE  DEPOSITARY,  OR BY A NOMINEE OF THE  DEPOSITARY TO
         THE  DEPOSITARY  OR  ANOTHER  NOMINEE  OF  THE  DEPOSITARY,  OR BY  THE
         DEPOSITARY  OR ANY SUCH NOMINEE TO A SUCCESSOR  DEPOSITARY OR SUCCESSOR
         NOMINEE,  AND (II) MAY NOT BE  EXCHANGED  OR  CANCELLED  EXCEPT  IN THE
         LIMITED CIRCUMSTANCES DESCRIBED IN THE INDENTURE."

                                       14

<page>

         (o) At such time as all  beneficial  interests in a  particular  Global
Security have been  exchanged for definitive  Securities or a particular  Global
Security has been  redeemed,  repurchased  or canceled in whole and not in part,
each such Global  Security  shall be returned to or retained and canceled by the
Trustee  in  accordance  with  Section  2.13  hereof.  At any time prior to such
cancellation,  if any beneficial  interest in a Global Security is exchanged for
or  transferred  to a Person  who will take  delivery  thereof  in the form of a
beneficial interest in another Global Security or for definitive Securities, the
principal  amount of Securities  represented  by such Global  Security  shall be
reduced  accordingly and an endorsement shall be made on such Global Security by
the Trustee or by the Depositary at the direction of the Trustee to reflect such
reduction;  and if the beneficial interest is being exchanged for or transferred
to a Person who will take delivery thereof in the form of a beneficial  interest
in another  Global  Security,  such other  Global  Security  shall be  increased
accordingly  and an  endorsement  shall be made on such  Global  Security by the
Trustee or by the  Depositary  at the  direction  of the Trustee to reflect such
increase.

         (p) Prior to due presentment for the  registration of a transfer of any
Security,  the Trustee,  any Agent and the Company may deem and treat the Person
in whose name any Security is registered as the absolute  owner of such Security
for the  purpose of  receiving  payment of  principal  of and  interest  on such
Securities and for all other  purposes,  and neither the Trustee,  any Agent nor
the Company  shall be affected by notice to the  contrary.  Notwithstanding  the
foregoing, with respect to any Global Security, nothing herein shall prevent the
Company,  the  Trustee or any agent of the  Company or the  Trustee  from giving
effect to any written certification,  proxy or other authorization  furnished by
any Depositary,  as a Holder, with respect to such Global Security or impair, as
between  such  Depositary  and owners of  beneficial  interests  in such  Global
Security,  the  operation of customary  practices  governing the exercise of the
rights of such Depositary (or its nominee) as Holder of such Global Security.

SECTION 2.09.     REPLACEMENT SECURITIES.

                  If any mutilated Security is surrendered to the Trustee or the
Company  and  the  Trustee   receives   evidence  to  its  satisfaction  of  the
destruction,  loss or theft of any  Security,  the  Company  shall issue and the
Trustee,   upon  receipt  of  an  Authentication  Order,  shall  authenticate  a
replacement  Security if the Trustee's  requirements are met. If required by the
Trustee or the Company, an indemnity bond must be supplied by the Holder that is
sufficient  in the  judgment  of the  Trustee  and the  Company to  protect  the
Company,  the Trustee, any Agent and any authenticating agent from any loss that
any of them may suffer if a Security is replaced. The Company may charge for its
expenses in replacing a Security.

                  Every replacement Security is an additional  obligation of the
Company and shall be entitled to all of the benefits of this  Indenture  equally
and proportionately with all other Securities duly issued hereunder.

SECTION 2.10.     OUTSTANDING SECURITIES.

                  The Securities  outstanding at any time are all the Securities
authenticated by the Trustee except for those canceled by it, those delivered to
it for  cancellation,  those  reductions  in the  interest in a Global  Security

                                       15

<page>

effected by the Trustee in  accordance  with the  provisions  hereof,  and those
described  in this  Section as not  outstanding.  Except as set forth in Section
2.11 hereof, a Security does not cease to be outstanding  because the Company or
an Affiliate of the Company holds the Security.

                  If a Security is replaced  pursuant to Section 2.09 hereof, it
ceases to be outstanding  unless the Trustee  receives proof  satisfactory to it
that the  replaced  Security  is held by a  "protected  purchaser"  (within  the
meaning of Article 8 of the Uniform Commercial Code) or a Person with comparable
status under other applicable law.

                  If the  principal  amount of any Security is  considered  paid
under Section 4.01 hereof, it ceases to be outstanding and interest on it ceases
to accrue.

                  If the Paying Agent (other than the Company,  a Subsidiary  or
an Affiliate of any thereof) holds, on a redemption date or maturity date, money
sufficient to pay Securities  payable on that date,  then on and after that date
such Securities  shall be deemed to be no longer  outstanding and shall cease to
accrue interest.

SECTION 2.11.     TREASURY SECURITIES.

                  In determining  whether the Holders of the required  principal
amount of  Securities  have  concurred  in any  direction,  waiver  or  consent,
Securities  owned  by the  Company,  or by any  Person  directly  or  indirectly
controlling or controlled by or under direct or indirect common control with the
Company,  shall be  considered  as though not  outstanding,  except that for the
purposes of determining whether the Trustee shall be protected in relying on any
such direction, waiver or consent, only Securities that the Trustee knows are so
owned shall be so disregarded.

SECTION 2.12.     TEMPORARY SECURITIES.

                  Until  certificates  representing  Securities  are  ready  for
delivery,  the  Company  may  prepare  and  the  Trustee,  upon  receipt  of  an
Authentication  Order,  shall  authenticate   temporary  Securities.   Temporary
Securities shall be substantially in the form of certificated Securities but may
have variations that the Company considers  appropriate for temporary Securities
and as shall be  reasonably  acceptable  to the  Trustee.  Without  unreasonable
delay, the Company shall prepare and the Trustee shall  authenticate  definitive
Securities in exchange for temporary Securities.

                  Holders of  temporary  Securities  shall be entitled to all of
the benefits of this Indenture.

SECTION 2.13.     CANCELLATION.

                  The Company at any time may deliver  Securities to the Trustee
for  cancellation.  The  Registrar and Paying Agent shall forward to the Trustee
any Securities  surrendered to them for  registration  of transfer,  exchange or
payment. The Trustee and no one else shall cancel all Securities surrendered for
registration of transfer,  exchange,  payment,  replacement or cancellation  and
shall destroy canceled Securities  (subject to the record retention  requirement
of  the  Exchange  Act).  Certification  of  the  destruction  of  all  canceled
Securities  shall be  delivered  to the  Company.  The Company may not issue new

                                       16

<page>

Securities to replace Securities that it has paid or that have been delivered to
the Trustee for cancellation.

SECTION 2.14.     DEFAULTED INTEREST.

                  If the  Company  defaults  in a  payment  of  interest  on the
Securities,  it shall pay the  defaulted  interest in any lawful manner plus, to
the extent lawful,  interest payable on the defaulted  interest,  to the Persons
who are Holders on a subsequent  special  record date,  in each case at the rate
provided in the  Securities.  The Company shall notify the Trustee in writing of
the amount of defaulted  interest  proposed to be paid on each  Security and the
date of the proposed  payment.  The Company  shall fix or cause to be fixed each
such special record date and payment date,  PROVIDED that no such special record
date  shall be less  than 10 days  prior to the  related  payment  date for such
defaulted interest. At least 15 days before the special record date, the Company
(or, upon the written request of the Company, the Trustee in the name and at the
expense  of the  Company)  shall  mail or cause to be mailed to Holders a notice
that states the special record date, the related  payment date and the amount of
such interest to be paid.  Subject to the foregoing  provisions of this Section,
each Security delivered under this Indenture upon registration of transfer of or
in  exchange  for or in lieu of any other  Security  shall  carry the  rights to
interest  accrued and unpaid,  and to accrue,  which were  carried by such other
Security.

                                   ARTICLE 3.
                            REDEMPTION AND PREPAYMENT

SECTION 3.01.     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 2.02 for Securities of such series.

SECTION 3.02.     SELECTION OF SECURITIES TO BE REDEEMED.

                  If less than all of the  Securities  of any  series  are to be
redeemed at any time,  the Trustee shall select the Securities of such series to
be redeemed  among the Holders of the  Securities  of such series in  compliance
with the requirements of the principal national securities exchange,  if any, on
which the  Securities  of such series are listed or, if the  Securities  of such
series are not so listed, to be redeemed among the Holders of Securities of such
series on a PRO RATA basis,  by lot or by such method as the Trustee  deems fair
and appropriate; PROVIDED that no Securities of $1,000 or less shall be redeemed
in part. In the event of partial redemption by lot, the particular Securities of
such series to be redeemed shall be selected,  unless otherwise provided herein,
not less  than 30 nor more  than 60 days  prior  to the  redemption  date by the
Trustee from the outstanding  Securities of the series not previously called for
redemption.

                  The Trustee  shall  promptly  notify the Company in writing of
the Securities selected for redemption and, in the case of any Security selected
for partial redemption, the principal amount thereof to be redeemed.  Securities
and  portions  of  Securities  selected  shall be in  amounts of $1,000 or whole
multiples  of  $1,000;  except  that if all of the  Securities  of a series of a

                                       17

Holder are to be redeemed,  the entire  outstanding amount of Securities of such
series held by such Holder, even if not a multiple of $1,000, shall be redeemed.
A new  Security of the same series in principal  amount equal to the  unredeemed
portion  thereof  will  be  issued  in the  name  of  the  Holder  thereof  upon
cancellation of the original  Security.  Securities  called for redemption shall
become due on the redemption  date. On and after the redemption  date,  interest
will  cease  to  accrue  on the  Securities  or  portions  of  them  called  for
redemption.  Except  as  provided  in  this  Section  3.02,  provisions  of this
Indenture  that apply to Securities  called for  redemption  shall also apply to
portions of Securities called for redemption.

SECTION 3.03.     NOTICE OF REDEMPTION.

                  At least 30 days but not more than 60 days before a redemption

notice of redemption to each Holder whose  Securities  are to be redeemed at its
registered address.

                  The notice  shall  identify  the  Securities  to be  redeemed,
including the series thereof, and shall state:

         (a) the redemption date;

         (b) the redemption price;

         (d) that  Securities  called for redemption  must be surrendered to the
Paying Agent to collect the redemption price;

         (e)  that,  unless  the  Company  defaults  in making  such  redemption
payment,  interest on Securities  called for redemption  will cease to accrue on
and after the redemption date;

         (f) that any  Security  being  redeemed  in part,  the  portion  of the
principal  amount of such Security to be redeemed and that, after the redemption
date upon surrender of such  Security,  a new Security or Securities of the same
series in principal amount equal to the unredeemed  portion shall be issued upon
cancellation of the original;

         (g) the paragraph of the  Securities  and/or  Section of this Indenture
pursuant to which the Securities called for redemption are being redeemed; and

         (h) that no representation is made as to the correctness or accuracy of
the CUSIP number, if any, listed in such notice or printed on the Securities.

                  At the Company's request, the Trustee shall give the notice of
redemption  in  the  Company's  name  and at the  Company's  expense;  PROVIDED,
HOWEVER,  that the Company shall have delivered to the Trustee, at least 30 days
prior to the  redemption  date,  an Officers'  Certificate  requesting  that the
Trustee give such notice and setting forth the  information to be stated in such
notice as provided in the preceding paragraph.

                                       18

SECTION 3.04.     EFFECT OF NOTICE OF REDEMPTION.

                  Once notice of redemption is mailed in accordance with Section
3.03 hereof, Securities called for redemption become irrevocably due and payable
on the redemption  date at the redemption  price. A notice of redemption may not
be conditional.

SECTION 3.05.     DEPOSIT OF REDEMPTION OR PURCHASE PRICE.

                  One Business  Day prior to 10:00 a.m.,  Eastern  Time,  on any
redemption  date,  the Company shall deposit with the Trustee or with the Paying
Agent money in immediately  available funds  sufficient to pay the redemption or
purchase price of and accrued interest, if any, on all Securities to be redeemed
or purchased on that date. The Trustee or the Paying Agent shall promptly return
to the Company any money  deposited  with the Trustee or the Paying Agent by the
Company in excess of the amounts  necessary  to pay the  redemption  or purchase
price of, and accrued interest on, all Securities to be redeemed or purchased.

SECTION 3.06.     SECURITIES REDEEMED OR PURCHASED IN PART.

                  Upon  surrender of a Security that is redeemed or purchased in
part,  the Company  shall issue and,  upon the Company's  written  request,  the
Trustee  shall  authenticate  for the Holder at the expense of the Company a new
Security of the same  series  equal in  principal  amount to the  unredeemed  or
unpurchased portion of the Security surrendered.

SECTION 3.07.     MANDATORY REDEMPTION; SINKING FUND.

                  The Company shall not be required to make mandatory redemption
or sinking  fund  payments  with  respect to the  Securities,  unless  otherwise
specified in the terms of a particular  series of Securities.  If a mandatory or
optional  sinking  fund is  specified  in the  terms of a  particular  series of
Securities,  the  following  provisions  will apply  thereto  (unless  otherwise
specified):

                  The minimum amount of any sinking fund payment provided for by
the terms of  Securities  of any series is herein  referred  to as a  "mandatory
sinking fund payment", and any payment in excess of such minimum amount provided
for by the  terms of  Securities  of any  series  is  herein  referred  to as an
"optional  sinking fund payment." The last date on which any such payment may be
made is herein referred to as a "sinking fund payment date."

                  In lieu of  making  all or any part of any  mandatory  sinking
fund payment with respect to any Securities of a series in cash, the Company may
at its option (a) deliver to the Trustee  Securities of that series  theretofore
purchased by the Company and (b) may apply as a credit Securities of that series
which have been redeemed  either at the election of the Company  pursuant to the
terms of such  Securities or through the  application  of optional  sinking fund
payments pursuant to the next succeeding paragraph, in each case in satisfaction
of all or any part of any  mandatory  sinking fund  payment,  provided that such
Securities have not been previously so credited. Each such Security so delivered
or applied as a credit  shall be credited at the sinking fund  redemption  price
for such  Securities  and the  amount of any  mandatory  sinking  fund  shall be

                                       19

<page>

reduced  accordingly.  If the  Company  intends  so to  deliver  or credit  such
Securities  with respect to any mandatory  sinking fund payment it shall deliver
to the  Trustee  at least 45 days  prior to the  next  succeeding  sinking  fund
payment date for such series (a) a certificate  signed by any Officer specifying
the portion of such sinking fund payment,  if any, to be satisfied by payment of
cash and the  portion  of such  sinking  fund  payment,  if any,  which is to be
satisfied by delivering and crediting such  Securities and (b) any Securities to
be so delivered.  All  Securities so delivered to the Trustee shall be cancelled
by the Trustee and no Securities shall be authenticated in lieu thereof.  If the
Company fails to deliver such  certificate  and Securities at or before the time
provided  above,  the Company  shall not be  permitted to satisfy any portion of
such mandatory sinking fund payment by delivery or credit of Securities.

                  At its option the Company  may pay into the  sinking  fund for
the retirement of Securities of any particular series, on or before each sinking
fund payment date for such series,  any  additional  sum in cash as specified by
the terms of such series of Securities.  If the Company  intends to exercise its
right to make any such optional  sinking fund  payment,  it shall deliver to the
Trustee at least 45 days prior to the next succeeding  sinking fund payment date
for such series of Securities a certificate  signed by any Officer  stating that
the Company  intends to exercise such optional  right and  specifying the amount
which the Company  intends to pay on such  sinking  fund  payment  date.  If the
Company fails to deliver such  certificate at or before the time provided above,
the Company  shall not be permitted  to make any  optional  sinking fund payment
with respect to such sinking fund payment date. To the extent that such right is
not exercised in any year it shall not be  cumulative or carried  forward to any
subsequent year.

                  If  the  sinking  fund  payment  or  payments   (mandatory  or
optional)  made in cash plus any unused  balance of any  preceding  sinking fund
payments made in cash shall exceed $50,000 (or a lesser sum if the Company shall
so request) with respect to the Securities of any particular series, it shall be
applied  by the  Trustee  or one or more  Paying  Agents 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.  The Trustee  shall select,  in the manner  provided in Section
3.02,  for  redemption on such sinking fund payment date a sufficient  principal
amount of  Securities  of such series to exhaust said cash, as nearly as may be,
and the Trustee shall, at the expense and in the name of the Company,  thereupon
cause  notice  of  redemption  of  Securities  of such  series  to be  given  in
substantially  the manner and with the effect provided in Sections 3.02 and 3.03
for the  redemption  of  Securities  of that series in part at the option of the
Company,  except  that the  notice  of  redemption  shall  also  state  that the
Securities of such series are being  redeemed for the sinking fund.  Any sinking
fund moneys not so applied or  allocated  by the Trustee or any Paying  Agent to
the  redemption  of  Securities  of that series  shall be added to the next cash
sinking fund payment  received by the Trustee or the Paying Agent and,  together
with such payment,  shall be applied in accordance  with the  provisions of this
Section 3.07.  Any and all sinking fund moneys held by the Trustee or any Paying
Agent on the maturity date of the Securities of any particular  series,  and not
held for the payment or  redemption  of  particular  Securities  of such series,
shall be  applied by the  Trustee  or such  Paying  Agent,  together  with other
moneys, if necessary, to be deposited sufficient for the purpose, to the payment
of the principal of the Securities of that series at maturity. On or before each
sinking fund  payment  date,  the Company  shall pay to the Trustee or to one or
more Paying Agents in cash a sum equal to all interest accrued to the date fixed
for redemption on Securities to be redeemed on the next  following  sinking fund
payment date pursuant to this Section.  Neither the Trustee nor any Paying Agent
shall  redeem any  Securities  of a series with  sinking  fund  moneys,  and the
Trustee shall not mail any notice of redemption of Securities for such series by
operation of the sinking fund, during the continuance of a default in payment of

                                       20

<page>

interest on such  Securities or of any Event of Default  (other than an Event of
Default occurring as a consequence of this paragraph), except that if the notice
of redemption of any Securities shall theretofore have been mailed in accordance
with the  provisions  hereof,  the Trustee or any paying agent shall redeem such
Securities  if cash  sufficient  for that purpose  shall be  deposited  with the
Trustee or such paying  agent for that purpose in  accordance  with the terms of
this  Article 3. 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 held as  security  for the payment of all
such  Securities;  provided,  however,  that in case such  Event of  Default  or
default  shall have been cured or waived as provided  herein,  such moneys shall
thereafter be applied on the next succeeding  sinking fund payment date on which
such moneys may be applied pursuant to the provisions of this Section 3.07.

premium,  if any, and interest on the  Securities on the dates and in the manner
provided in the Securities.  Principal,  premium,  if any, and interest shall be
considered  paid on the date due if the Paying Agent,  if other than the Company

an affiliate of the Trustee,  Registrar or co-Registrar) where Securities may be
surrendered  for  registration of transfer or for exchange and where notices and
demands to or upon the Company in respect of the  Securities  and this Indenture
may be served.  The Company shall give prompt  written  notice to the Trustee of
the location,  and any change in the location,  of such office or agency.  If at
any time the Company shall fail to maintain any such  required  office or agency
or  shall  fail  to  furnish  the  Trustee  with  the  address   thereof,   such
presentations,  surrenders,  notices  and  demands  may be made or served at the
Trustee's  principal  agency in the Borough of Manhattan,  the City of New York,
which currently is located at -----------------------------------------.

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

constitute   constructive  notice  of  any  information   contained  therein  or
determinable  from  information  contained  therein,   including  the  Company's
compliance  with any of its  covenants  hereunder  (as to which the  Trustee  is

Section 6.01 hereof) occurs and is continuing,  the Trustee or the Holders of at
least 25% in principal amount of the then  outstanding  Securities of all series
with respect to which an Event of Default  shall have occurred and be continuing
(treating all such series as a single  class) may declare all the  Securities of
all such series to be due and payable  immediately.  Upon any such  declaration,
the principal of, premium,  if any, and accrued and unpaid interest with respect
to the  Securities of all such series shall become due and payable  immediately.
Notwithstanding the foregoing, if an Event of Default specified in clause (e) or
(f) of Section 6.01 hereof occurs with respect to the Company,  all  outstanding
Securities of all series shall be due and payable  immediately  without  further
action or notice.

                                       25

SECTION 6.03.     OTHER REMEDIES.

                  If an Event of Default occurs and is  continuing,  the Trustee
may pursue any available remedy to collect the payment of principal, premium, if
any,  and  interest  on the  Securities  or to enforce  the  performance  of any
provision of the Securities or this Indenture.

                  The  Trustee  may  maintain a  proceeding  even if it does not
possess any of the Securities or does not produce any of them in the proceeding.
A delay or omission by the Trustee or any Holder of a Security in exercising any
right or remedy  accruing upon an Event of Default shall not impair the right or
remedy or constitute a waiver of or  acquiescence  in the Event of Default.  All
remedies are cumulative to the extent permitted by law.

SECTION 6.04.     WAIVER OF PAST DEFAULTS; RESCISSION OF ACCELERATION.

                  Holders of a majority  in  aggregate  principal  amount of the
then outstanding  Securities of all series affected (treating all such series as
a single  class) may, by notice to the Trustee,  on behalf of the Holders of all
of the  Securities  of all such  series,  waive an existing  Default or Event of
Default and its consequences hereunder (including in connection with an offer to
purchase or  exchange),  except a continuing  Default or Event of Default in the
payment of the principal of, premium,  if any,  interest on, or any sinking fund
payment with respect to, the Securities of such series,  and except a continuing
Default or Event of Default under any provision of this  Indenture  that,  under
Section  9.02,  cannot be  modified  or waived  without the consent of a greater
number of Holders or of each Holder affected. Upon any such waiver, such Default
or Event of Default shall be deemed to have been cured for every purpose of this
Indenture; but no such waiver shall extend to any subsequent or other Default or
Event of  Default  or impair  any right  consequent  thereon.  The  Holders of a
majority in aggregate principal amount of the then outstanding Securities of all
series affected (treating all such series as a single class) may also rescind an
acceleration and its consequences with respect to all such series, including any
related payment default that resulted from such acceleration,  but not including
any other payment default.

SECTION 6.05.     CONTROL BY MAJORITY.

                  Holders  of  a  majority  in  principal  amount  of  the  then
outstanding  Securities  of all series with respect to which an Event of Default
shall have  occurred  and be  continuing  (treating  all such series as a single
class) may direct the time,  method and place of conducting  any  proceeding for
exercising any remedy  available to the Trustee or exercising any trust or power
conferred on it;  provided that

                  (i)   such direction shall not be in conflict with any law  or
               rule or with this Indenture;

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

                  (iii) the Trustee need not take any action which might involve
               it in personal  liability or be unduly prejudicial to the Holders
               of Securities of such series not joining therein.

                                       26

SECTION 6.06.     LIMITATION ON SUITS.

                  A Holder of a Security  of any series may pursue a remedy with
respect to this Indenture or the Securities of such series only if:

             (a) the Holder of a Security of any or all series affected gives to
the Trustee written notice of a continuing Event of Default;

             (b) the  Holders  of at least 25% in  principal  amount of the then
outstanding  Securities  of all affected  series  (treating all such series as a
single class) make a written request to the Trustee to pursue the remedy;

             (c) such Holder or Holders offer and, if requested,  provide to the
Trustee  indemnity  satisfactory to the Trustee  against any loss,  liability or
expense;

             (d) the Trustee  does not comply  with the  request  within 30 days
after receipt of the request and the offer and, if  requested,  the provision of
indemnity; and

             (e)  during  such  30-day  period  the  Holders  of a  majority  in
principal amount of the then outstanding Securities of all such series (treating
all  such  series  as a  single  class)  do not give  the  Trustee  a  direction
inconsistent with the request.

                  A Holder of a Security may not use this Indenture to prejudice
the rights of another Holder of a Security or to obtain a preference or priority
over another Holder of a Security.

SECTION 6.07.     RIGHTS OF HOLDERS OF SECURITIES TO RECEIVE PAYMENT.

                  Notwithstanding  any other  provision of this  Indenture,  the
right of any Holder of a Security of any series to receive payment of principal,
premium,  if any, and interest on such Security,  on or after the respective due
dates  expressed in such  Security  (including  in  connection  with an offer to
purchase),  or to bring 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 6.08.     COLLECTION SUIT BY TRUSTEE.

                  If an Event of Default  specified  in  Section  6.01(a) or (b)
occurs and is continuing  with respect to any series of Securities,  the Trustee
is authorized  to recover  judgment in its own name and as Trustee of an express
trust against the Company for the whole amount of principal of, premium, if any,
and  interest  remaining  unpaid on such  Securities  and  interest  on  overdue
principal and, to the extent  lawful,  interest and such further amount as shall
be  sufficient  to cover the costs and  expenses of  collection,  including  the
reasonable  compensation,  expenses,  disbursements and advances of the Trustee,
its agents and counsel.

SECTION 6.09.     TRUSTEE MAY FILE PROOFS OF CLAIM.

                  The  Trustee is  authorized  to file such  proofs of claim and
other  papers or documents as may be necessary or advisable in order to have the

                                       27

<page>

claims of the  Trustee  (including  any claim for the  reasonable  compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel) and
the Holders of the Securities of any series allowed in any judicial  proceedings
relative  to the  Company  (or any  other  obligor  upon  the  Securities),  its
creditors  or its  property  and shall be  entitled  and  empowered  to collect,
receive and distribute any money or other property payable or deliverable on any
such  claims  and any  custodian  in any  such  judicial  proceeding  is  hereby
authorized by each Holder to make such payments to the Trustee, and in the event
that the Trustee shall  consent to the making of such  payments  directly to the
Holders,  to  pay to the  Trustee  any  amount  due  to it  for  the  reasonable
compensation,  expenses,  disbursements and advances of the Trustee,  its agents
and counsel, and any other amounts due the Trustee under Section 7.07 hereof. To
the extent that the payment of any such  compensation,  expenses,  disbursements
and advances of the Trustee,  its agents and counsel,  and any other amounts due
the Trustee under Section 7.07 hereof out of the estate in any such  proceeding,
shall be denied for any  reason,  payment of the same shall be secured by a lien
on,  and  shall be paid out of,  any and all  distributions,  dividends,  money,
securities and other  properties  that the Holders may be entitled to receive in
such proceeding  whether in liquidation or under any plan of  reorganization  or
arrangement or otherwise.  Nothing herein contained shall be deemed to authorize
the  Trustee  to  authorize  or  consent  to or accept or adopt on behalf of any
Holder  any  plan of  reorganization,  arrangement,  adjustment  or  composition
affecting  the  Securities  of any  series or the  rights of any  Holder,  or to
authorize  the Trustee to vote in respect of the claim of any Holder in any such
proceeding.

SECTION 6.10.     PRIORITIES.

                  If the Trustee  collects any money or other property  pursuant
to this Article,  it shall pay out the money or other  property in the following
order:

                  FIRST:  to the Trustee,  its agents and  attorneys for amounts
due under Section 7.07 hereof,  including payment of all  compensation,  expense
and  liabilities  incurred,  and all advances made, by the Trustee and the costs
and expenses of collection;

                  SECOND: to Holders of Securities for amounts due and unpaid on
the Securities for principal,  premium,  if any, interest and any other amounts,
ratably,  without  preference or priority of any kind,  according to the amounts
due and payable on the Securities for principal,  premium,  if any, interest and
other amounts, respectively; and

                  THIRD: to the Company or to such party as a court of competent
jurisdiction shall direct.

                  The Trustee  may fix a record  date and  payment  date for any
payment to Holders of Securities pursuant to this Section 6.10.

SECTION 6.11.     UNDERTAKING FOR COSTS.

                  In any suit for the  enforcement  of any right or remedy under
this  Indenture  or in any suit  against  the  Trustee  for any action  taken or
omitted by it as a Trustee,  a court in its discretion may require the filing by
any party  litigant in the suit of an  undertaking to pay the costs of the suit,
and  the  court  in  its  discretion  may  assess  reasonable  costs,  including
reasonable  attorneys' fees,  against any party litigant in the suit, having due
regard to the merits and good faith of the claims or defenses  made by the party
litigant.  This  Section  does not apply to a suit by the  Trustee,  a suit by a

                                       28

<page>

Holder of a Security  pursuant to Section 6.07  hereof,  or a suit by Holders of
more than 10% in  principal  amount of the then  outstanding  Securities  of any
series.

                                   ARTICLE 7.
                                    TRUSTEE

SECTION 7.01.     DUTIES OF TRUSTEE.

             (a) If an Event of Default  has  occurred  and is  continuing,  the
Trustee  shall  exercise  such of the  rights  and  powers  vested in it by this
Indenture or an indenture  supplemental  hereto, and use the same degree of care
and skill in its exercise,  as a prudent  person would exercise or use under the
circumstances in the conduct of its own affairs.

             (b) Except during the continuance of an Event of Default:

                  (i) the duties of the Trustee  shall be  determined  solely by
             the  express   provisions   of  this   Indenture  or  an  indenture
             supplemental hereto, and the Trustee need perform only those duties
             that are  specifically  set forth in this Indenture or an indenture
             supplemental  hereto and no others,  and no  implied  covenants  or
             obligations  shall be read  into  this  Indenture  or an  indenture
             supplemental hereto against the Trustee; and

                  (ii) in the absence of bad faith on its part,  the Trustee may
             conclusively  rely,  as to the  truth  of the  statements  and  the
             correctness of the opinions expressed therein, upon certificates or
             opinions   furnished   to  the  Trustee  and   conforming   to  the
             requirements of this Indenture.  However, the Trustee shall examine
             the  certificates  and  opinions to  determine  whether or not they
             conform to the requirements of this Indenture.

             (c) The Trustee may not be relieved  from  liabilities  for its own
negligent  action,  its  own  negligent  failure  to  act,  or its  own  willful
misconduct, except that:

                  (i) this  paragraph does not limit the effect of paragraph (b)
             of this Section;

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

                  (iii) the  Trustee  shall not be liable  with  respect  to any
             action it takes or omits to take in good faith in accordance with a
             direction received by it pursuant to Section 6.05 hereof.

             (d) Whether or not therein  expressly so provided,  every provision
of  this  Indenture  that  in any way  relates  to the  Trustee  is  subject  to
paragraphs (a), (b), and (c) of this Section.

             (e) No provision  of this  Indenture  shall  require the Trustee to
expend or risk its own funds or incur any liability.  The Trustee shall be under
no obligation  to exercise any of its rights and powers under this  Indenture at

                                       29

<page>

the  request of any  Holders,  unless  such  Holders  shall have  offered to the
Trustee security and indemnity satisfactory to it against any loss, liability or
expense.

             (f) The  Trustee  shall not be  liable  for  interest  on any money
received  by it except as the  Trustee  may agree in writing  with the  Company.
Money held in trust by the  Trustee  need not be  segregated  from  other  funds
except to the extent required by law.

SECTION 7.02.     RIGHTS OF TRUSTEE.

             (a) The Trustee may conclusively rely upon any document believed by
it to be genuine and to have been signed or presented by the proper Person.  The
Trustee need not investigate any fact or matter stated in the document.

             (b) Before the Trustee acts or refrains from acting, it may require
an Officers' Certificate or an Opinion of Counsel or both. The Trustee shall not
be liable for any action it takes or omits to take in good faith in  reliance on
such Officers'  Certificate or Opinion of Counsel.  The Trustee may consult with
counsel,  and the written advice of such counsel or any Opinion of Counsel shall
be full and complete  authorization  and protection from liability in respect of
any action  taken,  suffered  or omitted  by it  hereunder  in good faith and in
reliance thereon.

             (c) The Trustee may act through its  attorneys and agents and shall
not be responsible  for the misconduct or negligence of any agent appointed with
due care.

             (d) The  Trustee  shall  not be liable  for any  action it takes or
omits to take in good  faith that it  believes  to be  authorized  or within the
rights or powers conferred upon it by this Indenture.

             (e) Unless otherwise  specifically provided in this Indenture,  any
demand,  request,  direction or notice from the Company  shall be  sufficient if
signed by an Officer of the Company.

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

SECTION 7.03.     INDIVIDUAL RIGHTS OF TRUSTEE.

                  The Trustee in its individual or any other capacity may become
the owner or pledgee of Securities  and may  otherwise  deal with the Company or
any  Affiliate  of the Company with the same rights it would have if it were not
Trustee.  However,  in the  event  that the  Trustee  acquires  any  conflicting
interest  (within  the  meaning  of TIA  ss.  310(b))  it  must  eliminate  such
conflicting  interest  within  90  days  after  Default,  apply  to the  SEC for
permission  to continue as  trustee,  or resign.  Any Agent may do the same with
like rights and duties.

                                       30

<page>

SECTION 7.04.     TRUSTEE'S DISCLAIMER.

                  The  Trustee  shall  not  be  responsible  for  and  makes  no
representation  as to  the  validity  or  adequacy  of  this  Indenture  or  the
Securities;  it shall not be  accountable  for the Company's use of the proceeds
from the  Securities  or any money  paid to the  Company  or upon the  Company's
direction under any provision of this Indenture; it shall not be responsible for
the use or  application of any money received by any Paying Agent other than the
Trustee;  and it shall not be responsible for any statement or recital herein or
any  statement in the  Securities or any other  document in connection  with the
sale of the Securities or pursuant to this Indenture  other than its certificate
of authentication.

SECTION 7.05.     NOTICE OF DEFAULTS.

                  If a Default or Event of Default  occurs and is continuing and
if a Responsible  Officer of the Trustee has actual knowledge of such Default or
Event of Default,  the Trustee  shall mail to Holders of  Securities a notice of
the  Default or Event of Default  within 90 days after it occurs.  Except in the
case of a Default or Event of Default in payment of  principal  of, or  interest
on,  any  Security,  the  Trustee  may  withhold  the notice if and so long as a
committee of its Responsible  Officers in good faith determines that withholding
the notice is in the interests of the Holders of the Securities.

SECTION 7.06.     REPORTS BY TRUSTEE TO HOLDERS OF THE SECURITIES.

                  On or before July 31 of each year,  beginning with the July 31
following the date on which  Securities  are first issued under this  Indenture,
and for so long as Securities remain outstanding,  the Trustee shall mail to the
Holders of the  Securities a brief report dated as of such  reporting  date that
complies  with TIA ss.  313(a) (but if no event  described in TIA ss. 313(a) has
occurred  within the twelve months  preceding the reporting date, no report need
be  transmitted).  The Trustee  also shall  comply with TIA ss.  313(b)(2).  The
Trustee shall also transmit by mail all reports as required by TIA ss. 313(c). A
copy of each  report at the time of its  mailing to the  Holders  of  Securities
shall be mailed to the Company and filed with the SEC and each stock exchange on
which the Securities are listed in accordance  with TIA ss. 313(d).  The Company
shall  promptly  notify the Trustee when the  Securities are listed on any stock
exchange.

SECTION 7.07.     COMPENSATION AND INDEMNITY.

                  The Company  shall pay to the  Trustee  from time to time such
compensation for its acceptance of this Indenture and services  hereunder as the
Company and Trustee have separately agreed. The Trustee's compensation shall not
be limited by any law on  compensation  of a trustee  of an express  trust.  The

                                       31

<page>

Company  shall  reimburse the Trustee  promptly upon request for all  reasonable
disbursements,  advances and expenses  incurred or made by it in addition to the
compensation  for its  services.  Such  expenses  shall  include the  reasonable
compensation, disbursements and expenses of the Trustee's agents and counsel.

                  The Company shall  indemnify  the Trustee  against any and all
losses,  liabilities or expenses  incurred by it arising out of or in connection
with the  acceptance  or  administration  of its duties  under  this  Indenture,
including the costs and expenses of enforcing this Indenture against the Company
(including  this Section 7.07) and defending  itself  against any claim (whether
asserted  by the  Company or any Holder or any other  person)  or  liability  in
connection  with the  exercise  or  performance  of any of its  powers or duties
hereunder,  except to the  extent  any such loss,  liability  or expense  may be
attributable to its negligence or willful  misconduct.  The Trustee shall notify
the Company  promptly of any claim for which it may seek  indemnity.  Failure by
the  Trustee to so notify  the  Company  shall not  relieve  the  Company of its
obligations hereunder. The Company shall defend the claim, and the Trustee shall
cooperate in the defense. The Trustee may have separate counsel, and the Company
shall pay the reasonable fees and expenses of such counsel. The Company need not
pay for any  settlement  made without its consent,  which  consent  shall not be
unreasonably withheld.

                  The  obligations  of the Company under this Section 7.07 shall
survive the  satisfaction  and discharge of this  Indenture,  and the removal or
resignation of the Trustee.

                  To secure the Company's  payment  obligations in this Section,
the Trustee  shall have a lien prior to the  Securities on all money or property
held or collected by the Trustee, except that held in trust to pay principal of,
premium, if any, and interest on particular Securities.  Such lien shall survive
the satisfaction and discharge of this Indenture.

                  When the Trustee incurs expenses or renders  services after an
Event of Default specified in Section 6.01(e) or (f) hereof occurs, the expenses
and the  compensation  for the services  (including the fees and expenses of its
agents and counsel) are intended to constitute expenses of administration  under
any Bankruptcy Law.

SECTION 7.08.     REPLACEMENT OF TRUSTEE.

                  A resignation  or removal of the Trustee and  appointment of a
successor  Trustee  shall become  effective  only upon the  successor  Trustee's
acceptance of appointment as provided in this Section.

                  The  Trustee  may  resign  with  respect to one or more or all
series of Securities at any time and be discharged from the trust hereby created
by so notifying  the Company in writing.  The Holders of a majority in principal
amount of the then  outstanding  Securities of any series may remove the Trustee
with  respect to such  series by so  notifying  the  Trustee  and the Company in
writing. The Company may remove the Trustee if:

         (a) the Trustee  ceases to be eligible in accordance  with Section 7.10
hereof;

         (b) the  Trustee is  adjudged  bankrupt  or  insolvent  or an order for
relief is entered with respect to the Trustee under any Bankruptcy Law;

         (c) a custodian  or public  officer  takes charge of the Trustee or its
property; or

         (d) the Trustee becomes incapable of acting.

                  If the Trustee resigns or is removed or if a vacancy exists in
the office of Trustee  for any  reason,  the Company  shall  promptly  appoint a
successor Trustee. Within one year after the successor Trustee takes office, the

                                       32

<page>

Holders of a majority in principal amount of the then outstanding  Securities of
a series  may  appoint a  successor  Trustee to replace  the  successor  Trustee
appointed by the Company with respect to that series of Securities.

                  If a successor  Trustee  does not take  office  within 60 days
after the retiring  Trustee  resigns or is removed,  the retiring  Trustee,  the
Company,  or the  Holders  of at  least  10% in  principal  amount  of the  then
outstanding  Securities may petition any court of competent jurisdiction for the
appointment of a successor Trustee.

                  If the  Trustee,  after  written  request  by any  Holder of a
Security who has been a Holder of a Security for at least six months,  ceases to
be eligible in  accordance  with  Section  7.10,  such Holder of a Security  may
petition any court of competent  jurisdiction for the removal of the Trustee and
the appointment of a successor Trustee.

                  A successor Trustee shall deliver a written  acceptance of its
appointment  to  the  retiring  Trustee  and  to  the  Company.  Thereupon,  the
resignation or removal of the retiring Trustee shall become  effective,  and the
successor  Trustee  shall have all the rights,  powers and duties of the Trustee
under  this  Indenture.  The  successor  Trustee  shall  mail  a  notice  of its
succession to Holders of the  Securities.  The retiring  Trustee shall  promptly
transfer all property held by it as Trustee to the successor  Trustee,  PROVIDED
all sums owing to the Trustee  hereunder  have been paid and subject to the lien
provided for in Section 7.07 hereof.  Notwithstanding replacement of the Trustee
pursuant to this Section  7.08,  the  Company's  obligations  under Section 7.07
hereof shall continue for the benefit of the retiring Trustee.

                  If a  successor  Trustee  is  appointed  with  respect  to the
Securities  of one or more  (but not all)  series,  the  Company,  the  retiring
Trustee  and each  successor  Trustee  with  respect  to the  Securities  of 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 retiring 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

         (a) The Company may, at the option of its Board of Directors  evidenced

obligation  of the Company to convert or exchange  Securities  of such series as

establishing  such Series) (1) if (i) all Securities of such series  theretofore
authenticated and delivered  (except lost,  stolen or destroyed  Securities that
have been  replaced  or paid and  Securities  for whose  payment  cash in United
States dollars has theretofore been deposited in trust or segregated and held in
trust by the Company and  thereafter  repaid to the Company or  discharged  from
such trust as provided in Section  8.06) have been  delivered to the Trustee for

pursuant  to Article 3, have given  notice to the Trustee and mailed a notice of
redemption to each Holder of Securities of such series of the  redemption of all
of such Securities under arrangements satisfactory to the Trustee for the giving
of such notice or (B) all  Securities of such series have  otherwise  become due
and payable  hereunder or will become due and payable within one year;  (ii) the
Company  shall have  irrevocably  deposited or caused to be  deposited  with the
Trustee  (or a  trustee  satisfactory  to the  Trustee,  under  the  terms of an
irrevocable trust agreement in form and substance  satisfactory to the Trustee),

such series for that purpose, cash in United States dollars in such amount as is
sufficient  without  consideration of reinvestment of interest or other earnings

                                       35

on such cash, to pay the entire  indebtedness on such Securities not theretofore
delivered to the Trustee for  cancellation,  for the principal of,  premium,  if
any, and interest on the  outstanding  Securities  of such series to the date of
such deposit (in the case of Securities which have become due and payable) or to
the stated maturity or redemption  date, as the case may be; (iii) no Default or
Event of Default with respect to this  Indenture  or the  Securities  shall have
occurred  and be  continuing  on the date of such  deposit  or shall  occur as a
result of such deposit and such deposit will not result in a breach or violation

bound;  (iv) the Company  shall have paid all other sums payable by it hereunder
in  respect  of  Securities  of such  series;  and (v) the  Company  shall  have
delivered  to the Trustee an  Officers'  Certificate  and an Opinion of Counsel,

discharge of this Indenture have been complied with.

obligations in Sections 2.07, 2.08, 2.09, 2.10, 4.01, including any provision of
the applicable Board Resolution or indenture supplemental hereto relating to the
payment of  principal,  premium or  interest,  4.02,  7.07,  8.06 and 8.07 shall
survive with respect to the Securities of the  applicable  series until they are
no longer outstanding  pursuant to the last paragraph of Section 2.10. After the
Securities  of the  applicable  series are no longer  outstanding,  the Issuer's
obligations  in  Sections  7.07,  8.06 and 8.07  shall  survive  in  respect  of
Securities of the applicable series.

                  After such delivery or irrevocable  deposit,  the Trustee upon
request shall acknowledge in writing the discharge of the Company's  obligations
under the  Securities of the  applicable  series and the  Company's  obligations
under this Indenture  with respect to the Securities of such series,  except for
those surviving obligations specified above.

SECTION 8.02.     LEGAL DEFEASANCE AND DISCHARGE.

                  Upon the Company's  exercise  under Section 8.01 hereof of the
option  applicable  to this  Section  8.02  relating  to one or more  series  of
Securities, the Company shall, upon the satisfaction of the conditions set forth
in Section 8.04 hereof,  be deemed to have been  discharged from its obligations
with  respect  to all  outstanding  Securities  of such  series  on the date the
conditions set forth below are satisfied (hereinafter,  "LEGAL DEFEASANCE"). For
this purpose,  Legal  Defeasance  means that the Company shall be deemed to have
paid and  discharged  the entire  indebtedness  represented  by the  outstanding
Securities  of the  applicable  series,  which shall  thereafter be deemed to be
"OUTSTANDING"  only for the  purposes  of  Section  8.05  hereof  and the  other
Sections  of  this  Indenture  referred  to in (a) and  (b)  below,  and to have
satisfied all of its other  obligations  under the  Securities of the applicable
series and under the provisions of this Indenture applicable to such series (and
the  Trustee,  on demand of and at the  expense of the  Company,  shall  execute
proper instruments  acknowledging the same), except for the following provisions
which shall survive until otherwise terminated or discharged hereunder:  (a) the
rights of Holders of outstanding  Securities of the applicable series to receive
solely from the trust fund  described in Section 8.04 hereof,  and as more fully
set forth in such Section,  payments in respect of the principal of, premium, if
any,  and  interest,  on such  Securities  when such  payments  are due, (b) the
Company's  obligations  with  respect  to such  Securities  under  Article 2 and
Section 4.02 hereof, (c) the rights,  powers,  trusts,  duties and immunities of
the Trustee hereunder, and the Company's obligations in connection therewith and
(d) this Article 8. Subject to  compliance  with this Article 8, the Company may

                                       35

<page>

exercise its option under this Section 8.02  notwithstanding  the prior exercise
of its option under Section 8.03 hereof.

SECTION 8.03.     COVENANT DEFEASANCE.

                  Upon the Company's  exercise  under Section 8.01 hereof of the
option  applicable  to this  Section  8.03  relating  to one or more  series  of
Securities, the Company shall, upon the satisfaction of the conditions set forth
in Section 8.04 hereof,  be released  from its  obligations  under the covenants
contained  in Sections  4.03,  4.04,  4.05 and 4.06  hereof with  respect to the
outstanding  Securities of the applicable  series, and under any other covenants
specified in the supplemental  indenture or other terms of the applicable series
as  covenants  to which  this  Section  8.03  apply,  on and  after the date the
conditions set forth below are satisfied  (hereinafter,  "COVENANT DEFEASANCE"),
and the  Securities  of the  applicable  series shall  thereafter  be deemed not
"OUTSTANDING" for the purposes of any direction,  waiver, consent or declaration
or act of Holders (and the  consequences of any thereof) in connection with such
covenants,  but shall continue to be deemed "OUTSTANDING" for all other purposes
hereunder (it being  understood  that the  Securities of the  applicable  series
shall not be deemed  outstanding  for  accounting  purposes).  For this purpose,
Covenant Defeasance means that, with respect to the "OUTSTANDING"  Securities of
the  applicable  series,  the  Company may omit to comply with and shall have no
liability in respect of any term,  condition or limitation set forth in any such
covenant,  whether directly or indirectly,  by reason of any reference elsewhere
herein to any such  covenant or by reason of any  reference in any such covenant
to any other  provision  herein or in any other  document  and such  omission to
comply shall not  constitute a Default or an Event of Default under Section 6.01
hereof, but, except as specified above, the remainder of this Indenture and such
Securities shall be unaffected thereby.

SECTION 8.04.     CONDITIONS TO LEGAL OR COVENANT DEFEASANCE.

                  The following  shall be the  conditions to the  application of
either Section 8.02 or 8.03 hereof to the outstanding  Securities of one or more
series:

                  In order to  exercise  either  Legal  Defeasance  or  Covenant
Defeasance:

         (a) the Company must irrevocably deposit with the Trustee,  (or another
trustee  satisfying the  requirements of Section 7.10, who shall agree to comply
with the  provisions  of this  Article 8  applicable  to it) in  trust,  for the
benefit of the Holders of the Securities of the applicable series, (i) an amount
of cash in United States dollars, (ii) non-callable U.S. Government  Obligations
which, through scheduled payment of principal and interest in respect thereof in
accordance  with their  terms,  will  provide,  not later than one  Business Day
before the due date of any payment of principal of, premium, if any, or interest
on the  Securities  of such series,  cash in an amount,  or (iii) a  combination
thereof,  sufficient,  in  the  opinion  of  a  nationally  recognized  firm  of
independent public  accountants,  to pay the principal of, interest and premium,
if any, on the  outstanding  Securities of the  applicable  series on the Stated
Maturity  or on the  applicable  redemption  date,  as the case may be,  and any
mandatory  sinking fund payments  applicable to the Securities of such series on
the day on which such payments are due, and the Company must specify whether the
Securities  of the  applicable  series are being  defeased  to  maturity or to a
particular redemption date;

                                       36

<page>

         (b) in the case of an election  under Section 8.02 hereof,  the Company
shall have  delivered to the Trustee an Opinion of Counsel in the United  States
reasonably  acceptable  to the  Trustee  confirming  that  (i) the  Company  has
received  from, or there has been published by, the Internal  Revenue  Service a
ruling or (ii) since the date of this Indenture,  there has been a change in the
applicable  federal income tax law, in either case to the effect that, and based
thereon  such  Opinion  of  Counsel  shall  confirm  that,  the  Holders  of the
outstanding  Securities of the applicable series will not recognize income, gain
or loss for federal income tax purposes as a result of such Legal 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 Legal  Defeasance  had
not occurred;

         (c) in the case of an election  under Section 8.03 hereof,  the Company
shall have  delivered to the Trustee an Opinion of Counsel in the United  States
reasonably  acceptable  to  the  Trustee  confirming  that  the  Holders  of the
outstanding  Securities of the applicable 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;

         (d)  no  Default  or  Event  of  Default  shall  have  occurred  and be
continuing on the date of such deposit (other than a Default or Event of Default
resulting  from the borrowing of funds to be applied to such deposit) or insofar
as  Sections  6.01(e)  or (f) hereof  are  concerned,  at any time in the period
ending on the 91st day after the date of deposit (or  greater  period of time in
which any such  deposit of trust  funds may  remain  subject  to  bankruptcy  or
insolvency laws insofar as those apply to the deposit by the Company);

         (e) the  Company  shall have  delivered  to the  Trustee  an  Officers'
Certificate  and an  Opinion  of  Counsel,  each  stating  that  all  conditions
precedent  provided  for or relating  to the Legal  Defeasance  or the  Covenant
Defeasance have been complied with.

SECTION 8.05.     DEPOSITED MONEY AND U.S. GOVERNMENT OBLIGATIONS TO BE HELD IN
                  TRUST; OTHER MISCELLANEOUS PROVISIONS.

                  Subject to Section  8.06  hereof,  all money and  non-callable
U.S. Government  Obligations (including the proceeds thereof) deposited with the
Trustee (or other qualifying trustee,  collectively for purposes of this Section
8.05,  the  "TRUSTEE")  pursuant  to  Section  8.04  hereof  in  respect  of the
outstanding  Securities  of the  applicable  series  shall be held in trust  and
applied by the Trustee, in accordance with the provisions of such Securities and
this  Indenture,  to the  payment,  either  directly or through any Paying Agent
(including the Company acting as Paying Agent) as the Trustee may determine,  to
the  Holders of such  Securities  of all sums due and to become  due  thereon in
respect of principal,  premium, if any, and interest, but such money need not be
segregated from other funds except to the extent required by law.

                  The Company shall pay and  indemnify  the Trustee  against any
tax, fee or other charge imposed on or assessed against the cash or non-callable
U.S.  Government  Obligations  deposited  pursuant to Section 8.04 hereof or the

                                       37

<page>

principal and interest  received in respect thereof other than any such tax, fee
or  other  charge  which  by law is  for  the  account  of  the  Holders  of the
outstanding Securities of the applicable series.

                  Anything in this  Article 8 to the  contrary  notwithstanding,
the  Trustee  shall  deliver  or pay to the  Company  from time to time upon the
request of the Company any money or  non-callable  U.S.  Government  Obligations
held by it as  provided  in  Section  8.04  hereof  which,  in the  opinion of a
nationally  recognized  firm of independent  public  accountants  expressed in a
written certification thereof delivered to the Trustee (which may be the opinion
delivered  under Section  8.04(a)  hereof),  are in excess of the amount thereof
that  would then be  required  to be  deposited  to effect an  equivalent  Legal
Defeasance or Covenant Defeasance of the applicable series.

SECTION 8.06.     REPAYMENT TO COMPANY.

                  Any money and U.S. Government  Obligations  deposited with the
Trustee  or any  Paying  Agent,  or then held by the  Company,  in trust for the
payment of the principal  of,  premium or interest on any Security and remaining
unclaimed for two years after such principal,  and premium,  if any, or interest
has become due and  payable  shall be paid to the  Company on its request or (if
then held by the Company) shall be discharged from such trust; and the Holder of
such Security shall thereafter look only to the Company for payment thereof, and
all liability of the Trustee or such Paying Agent with respect to such money and
U.S.  Government  Obligations,  and all  liability  of the  Company  as  trustee
thereof,  shall thereupon  cease;  PROVIDED,  HOWEVER,  that the Trustee or such
Paying  Agent,  before  being  required to make any such  repayment,  may at the
expense of the Company cause to be published once, in the NEW YORK TIMES and THE
WALL STREET JOURNAL (national edition), notice that such money remains unclaimed
and that, after a date specified  therein,  which shall not be less than 30 days
from the date of such notification or publication, any unclaimed balance of such
money then remaining will be repaid to the Company.

SECTION 8.07.     REINSTATEMENT.

                  If the  Trustee or Paying  Agent is unable to apply any United
States dollars or non-callable U.S. Government Obligations deposited pursuant to
Section  8.02 or 8.03  hereof,  as the case may be,  by  reason  of any order or
judgment  of any  court or  governmental  authority  enjoining,  restraining  or
otherwise  prohibiting  such  application,  then the  obligations of the Company
under this  Indenture  and the  Securities  shall be revived and  reinstated  as
though no deposit had  occurred  pursuant to Section  8.02 or 8.03 hereof  until
such time as the Trustee or Paying Agent is permitted to apply all such money in
accordance  with  Section  8.02 or 8.03  hereof,  as the case may be;  PROVIDED,
HOWEVER,  that,  if the Company  makes any payment of principal  of,  premium or
interest on any Security  following the  reinstatement of its  obligations,  the
Company shall be  subrogated to the rights of the Holders of such  Securities to
receive such payment from the money held by the Trustee or Paying Agent.

SECTION 9.01.     WITHOUT CONSENT OF HOLDERS OF SECURITIES.

                  Notwithstanding  Section 9.02 of this  Indenture,  the Company
and the Trustee may amend or supplement this Indenture or the Securities without
the consent of any Holder of a Security:

         (a) to evidence the  succession  of another  Person to the Company,  or
successive  successions,  and the  assumption  by the  successor  Person  of the
covenants,  agreements  and  obligations  of the  Company  pursuant to Article 5
hereof;

         (b) to add to the  covenants  of the Company  such  further  covenants,
restrictions  or  conditions  for the  protection  of the  Holders of all or any
series of  Securities  (and if such  covenants are to be for the benefit of less
than all series of Securities  stating that such  covenants are expressly  being
included  for the  benefit  of such  series) as the Board of  Directors  and the
Trustee  shall  consider  to be for  the  protection  of  the  Holders  of  such
Securities, and to make the occurrence, or the occurrence and continuance,  of a
default  in any of such  additional  covenants,  restrictions  or  conditions  a
default or an Event of Default  permitting the  enforcement of all or any of the
several  remedies  provided  in this  Indenture  as herein set forth;  provided,
however,  that in  respect  of any  such  additional  covenant,  restriction  or
condition  such  supplemental  indenture may provide for a particular  period of
grace after default  (which period may be shorter or longer than that allowed in
the case of other  defaults)  or may provide for an immediate  enforcement  upon
such  default  or may limit the  remedies  available  to the  Trustee  upon such
default;

         (c) to provide for the issuance  under this  Indenture of Securities in
coupon form  (including  Securities  registrable  as to  principal  only) and to
provide  for  exchangeability  of such  Securities  with the  Securities  issued
hereunder in fully registered form and to make all appropriate  changes for such
purpose;

         (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;  provided that any such action shall not adversely
affect the interests of the Holders of the Securities;

         (e) 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
7.08;

         (f) to make any change that does not adversely affect the rights of any
Holder; or

         (g) to provide for the issuance of and establish the form and terms and
conditions  of the  Securities  of any  series,  to  establish  the  form of any
certifications  required to be furnished pursuant to the terms of this Indenture
or any  series of  Securities,  or to add to the  rights of the  Holders  of any
series of Securities.

                  Upon the  request of the  Company  accompanied  by a copy of a
Board  Resolution,  certified by the Secretary or an Assistant  Secretary of the
Company to have been duly  adopted by the Board of  Directors  and to be in full
force and effect on the date of the  certificate,  authorizing  the execution of
any such amended or supplemental  indenture,  and upon receipt by the Trustee of
the documents  described in Section 7.02 hereof, the Trustee shall join with the
Company in the execution of any amended or supplemental  indenture authorized or
permitted  by the terms of this  Indenture  and to make any further  appropriate
agreements and stipulations that may be therein contained, but the Trustee shall
not be  obligated  to enter into such  amended or  supplemental  indenture  that
affects its own rights, duties or immunities under this Indenture or otherwise.

SECTION 9.02.     WITH CONSENT OF HOLDERS OF SECURITIES.

                  Except as provided below in this Section 9.02, the Company and
the Trustee may amend or supplement  this  Indenture,  or the  Securities of any
series may be  amended or  supplemented,  with the  consent of the  Holders of a
majority in principal  amount of the Securities  then  outstanding of all series
affected by such supplemental  indenture (voting as a single class)  (including,
without  limitation,  consents  obtained in  connection  with a purchase  of, or
tender offer or exchange offer for,  Securities),  and, subject to Sections 6.04
and 6.07 hereof,  any existing Default or Event of Default (other than a Default
or Event of Default in the payment of the principal  of,  premium or interest on
the  Securities)  or  compliance  with any  provision  of this  Indenture or the
Securities  of such  series may be waived  with the  consent of the Holders of a
majority in principal  amount of the Securities  then  outstanding of all series
affected  by  such  waiver  (voting  as  a  single  class)  (including,  without
limitation,  consents obtained in connection with a purchase of, or tender offer
or exchange offer for the Securities).

                  Upon the  request of the  Company  accompanied  by a copy of a
Board  Resolution,  certified by the Secretary or an Assistant  Secretary of the
Company to have been duly  adopted by the Board of  Directors  and to be in full
force and effect on the date of the  certificate,  authorizing  the execution of
any such amended or supplemental indenture, and upon the filing with the Trustee
of  evidence  satisfactory  to the  Trustee  of the  consent  of the  Holders of
Securities of each such series as aforesaid,  and upon receipt by the Trustee of
the documents  described in Section 7.02(b) hereof,  the Trustee shall join with
the Company in the execution of such amended or  supplemental  indenture  unless
such amended or 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 amended or
supplemental indenture.

                  It shall not be  necessary  for the  consent of the Holders of
Securities  under  this  Section  9.02 to  approve  the  particular  form of any
proposed  amendment  or  waiver,  but it shall  be  sufficient  if such  consent
approves the substance thereof.

                  After an  amendment,  supplement  or waiver under this Section
9.02 becomes  effective,  the Company shall mail to the Holders of Securities of
such  series  affected  thereby  a  notice  briefly  describing  the  amendment,
supplement  or waiver.  Any failure of the Company to mail such  notice,  or any
defect therein,  shall not, however, in any way impair or affect the validity of
any such amended or supplemental indenture or waiver.

<page>

                  However,  without  the  consent of each  Holder of  Securities
affected, an amendment or waiver may not (with respect to any Securities held by
a non-consenting Holder):

         (a) reduce the principal  amount of the  Securities  whose Holders must
consent to an amendment, supplement or waiver;

         (b)  reduce  the  principal  of or  change  the fixed  maturity  of the
principal of, premium,  if any, or mandatory  sinking fund  obligation,  if any,
with  respect  to any  Securities  of any  series or alter the  provisions  with
respect to the redemption of the Securities;

         (c)  reduce the rate of or change  the time for  payment  of  interest,
including default interest, on any Security of any series;

         (d) waive a Default or Event of Default in the payment of  principal of
or interest or premium on the  Securities of any series  (except a rescission of
acceleration  of the  Securities  by the  Holders  of a  majority  in  aggregate
principal  amount of the Securities of one or more affected  series and a waiver
of the payment default that resulted from such acceleration);

         (e) make any Security of any series payable in currency other than that
stated in the Securities of such series;

         (f) make any change in the  provisions  of this  Indenture  relating to
waivers of past  Defaults  or the rights of  Holders  of  Securities  to receive
payments of principal of or interest or premium on the Securities;

         (g) waive a redemption payment with respect to any Security; or

SECTION 9.03.     COMPLIANCE WITH TRUST INDENTURE ACT.

                  Every  amendment  or  supplement  to  this  Indenture  or  the
Securities  shall be set forth in an  amended  or  supplemental  indenture  that
complies with the TIA as then in effect.

SECTION 9.04.     REVOCATION AND EFFECT OF CONSENTS.

                  Until an amendment,  supplement or waiver becomes effective, a
consent to it by a Holder of a Security is a continuing consent by the Holder of
a Security  and every  subsequent  Holder of a Security or portion of a Security
that  evidences the same debt as the  consenting  Holder's  Securities,  even if
notation of the consent is not made on any Securities.  However, any such Holder
of a Security or  subsequent  Holder of a Security  may revoke the consent as to
its Securities if the Trustee receives  written notice of revocation  before the
date the waiver,  supplement  or  amendment  becomes  effective.  An  amendment,
supplement  or  waiver  becomes  effective  in  accordance  with its  terms  and
thereafter binds every Holder.

SECTION 9.05.     NOTATION ON OR EXCHANGE OF SECURITIES.

                  The  Trustee  may  place  an  appropriate  notation  about  an
amendment, supplement or waiver on any Securities thereafter authenticated.  The
Company  in  exchange  for  all  Securities  may  issue  and the  Trustee  shall
authenticate new Securities that reflect the amendment, supplement or waiver.

                  Failure  to make the  appropriate  notation  or to  issue  new
Securities  shall  not  affect  the  validity  and  effect  of  such  amendment,
supplement or waiver.

SECTION 9.06.     TRUSTEE TO SIGN AMENDMENTS, ETC.

                  The  Company  may  not  sign  an  amendment  or   supplemental
indenture  until its Board of Directors  approves it. The Trustee shall sign any
amendment or supplemental indenture authorized pursuant to this Article 9 if the
amendment  or  supplement  does  not  adversely   affect  the  rights,   duties,
liabilities or immunities of the Trustee.  If it does, the Trustee may, but need
not,  sign it. In signing or refusing  to sign such  amendment  or  supplemental
indenture, the Trustee shall be entitled to receive and shall be fully protected
in  relying  upon,  an  Officers'  Certificate  and an  Opinion  of  Counsel  as
conclusive evidence that such amendment or supplemental  indenture is authorized
or permitted by this Indenture,  that it is not inconsistent  herewith, and that
it will be valid and binding upon the Company in accordance with its terms.

SECTION 10.04.    QUORUM; ACTION.

                  The Persons entitled to vote a majority in principal amount of

of Holders of Securities of such series;  provided,  however, that if any action
is to be taken at such  meeting  with  respect to a consent or waiver which this
Indenture (or any Board Resolution or indenture supplemental hereto establishing
a series of Securities hereunder) expressly provides may be given by the Holders
of  more  or  less  than a  majority  in  principal  amount  of the  outstanding
Securities  of a  series,  the  Persons  entitled  to vote  such  percentage  in
principal amount of the outstanding Securities of such series shall constitute a
quorum.  In the absence of a quorum within 30 minutes  after the time  appointed
for any such meeting,  the meeting shall,  if convened at the request of Holders
of Securities of such series, be dissolved. In any other case the meeting may be
adjourned for a period of not less than 10 days as determined by the chairman of
the meeting prior to the adjournment of such meeting. In the absence of a quorum
at any such adjourned  meeting,  such adjourned meeting may be further adjourned
for a period  of not less  than 10 days as  determined  by the  chairman  of the
meeting  prior to the  adjournment  of such  adjourned  meeting.  Notice  of the
reconvening of any such adjourned  meeting shall be given as provided in Section
10.02(a),  except  that such  notice  need be given only once not less than five
days  prior to the date on which the  meeting  is  scheduled  to be  reconvened.
Notice of the  reconvening  of an adjourned  meeting  shall state  expressly the
percentage,  as  provided  above,  of the  principal  amount of the  outstanding
Securities of such series which shall constitute a quorum.

                  Except as  otherwise  provided in Section  6.02 or 9.02 (or in
any Board Resolution or indenture  supplemental  hereto establishing a series of
Securities  hereunder),  any  resolution  presented  to a meeting  or  adjourned
meeting duly reconvened at which a quorum is present as aforesaid may be adopted
only by the affirmative vote of the Holders of a majority in principal amount of
the outstanding  Securities of that series;  provided,  however, that, except as
otherwise  provided  in  Section  6.02 or 9.02 (or in any  Board  Resolution  or
indenture  supplemental hereto  establishing a series of Securities  hereunder),
any resolution with respect to any request,  demand,  authorization,  direction,
notice, consent, waiver or other action which this Indenture or any supplemental
indenture  expressly  provides  may be made,  given or taken by the Holders of a
specified  percentage  in principal  amount of the  outstanding  Securities of a
series may be adopted at a meeting or an adjourned  meeting duly  reconvened and
at which a quorum is present as aforesaid by the affirmative vote of the Holders

                                       43

of such specified  percentage in principal amount of the outstanding  Securities
of such series.

                  Any  resolution  passed or  decision  taken at any  meeting of
Holders of Securities  of any series duly held in  accordance  with this Section
shall be binding on all the Holders of Securities of such series, whether or not
such  Holders  were  present  or  represented  at the  meeting.  SECTION  10.05.
DETERMINATION OF VOTING RIGHTS; CONDUCT AND ADJOURNMENT OF MEETINGS.

         (a) Notwithstanding any other provisions of this Indenture, the Trustee
may make such reasonable regulations as it may deem advisable for any meeting of
Holders  of  Securities  of a  series  in  regard  to proof  of the  holding  of
Securities of such series and of the appointment of proxies and in regard to the
appointment and duties of inspectors of votes, the submission and examination of
proxies,  certificates  and other  evidence of the right to vote, and such other
matters  concerning  the  conduct of the  meeting as it shall deem  appropriate.
Except as otherwise  permitted or required by any such regulations,  the holding
of  Securities  shall be proved in the manner  specified in Section 1.05 and the
appointment  of any proxy  shall be proved in the  manner  specified  in Section
1.05. Such regulations may provide that written instruments  appointing proxies,
regular on their  face,  may be  presumed  valid and  genuine  without the proof
specified in Section 1.05 or other proof.

         (b) The Trustee shall, by an instrument in writing, appoint a temporary
chairman  of the  meeting,  unless the  meeting  shall  have been  called by the
Company or by Holders of  Securities as provided in Section  10.02(b),  in which
case the Company or the Holders of Securities of the series calling the meeting,
as the case  may be,  shall in like  manner  appoint  a  temporary  chairman.  A
permanent chairman and a permanent  secretary of the meeting shall be elected by
vote of the Persons  entitled to vote at least a majority in principal amount of
the outstanding Securities of such series represented at the meeting.

         (c) At any  meeting  each  Holder of a Security of such series or proxy
shall be entitled to one vote for each $25 principal  amount of the  outstanding
Securities of such series held or represented by him; provided, however, that no
vote  shall  be cast or  counted  at any  meeting  in  respect  of any  Security
challenged as not outstanding and ruled by the chairman of the meeting to be not
outstanding.  The chairman of the meeting shall have no right to vote, except as
a Holder of a Security of such series or proxy.

         (d) Any  meeting of Holders of  Securities  of any series  duly  called
pursuant  to Section  10.02 at which a quorum is present may be  adjourned  from
time to time by Persons entitled to vote at least a majority in principal amount
of the outstanding Securities of such series represented at the meeting; and the
meeting may be held as so adjourned without further notice.

SECTION 10.06.    COUNTING VOTES AND RECORDING ACTION OF MEETINGS.

         (a) The vote upon any resolution submitted to any meeting of Holders of
Securities  of any  series  shall  be by  written  ballots  on  which  shall  be
subscribed  the  signatures  of the Holders of  Securities  of such series or of
their  representatives  by proxy and the principal amounts and serial numbers of

                                       44

<page>

the  outstanding  Securities  of such series held or  represented  by them.  The
permanent  chairman of the meeting  shall  appoint two  inspectors  of votes who
shall count all votes cast at the meeting for or against any  resolution and who
shall make and file with the  secretary of the meeting  their  verified  written
reports in  duplicate of all votes cast at the  meeting.  A record,  at least in
duplicate,  of the  proceedings  of each meeting of Holders of Securities of any
series  shall be  prepared  by the  secretary  of the meeting and there shall be
attached to said record the original  reports of the  inspectors of votes on any
vote by ballot  taken  thereat  and  affidavits  by one or more  persons  having
knowledge  of the facts  setting  forth a copy of the notice of the  meeting and
showing  that said  notice  was given as  provided  in  Section  10.02  and,  if
applicable,  Section  10.04.  Each copy  shall be  signed  and  verified  by the
affidavits of the  permanent  chairman and secretary of the meeting and one such
copy  shall be  delivered  to the  Company,  and  another  to the  Trustee to be
preserved by the Trustee,  the latter to have attached thereto the ballots voted
at the meeting.  Any record so signed and verified shall be conclusive  evidence
of the matters therein stated.

of 15 days before a selection of Notes to be redeemed.

                  9. PERSONS DEEMED OWNERS.  The registered Holder of a Note may
be treated as its owner for all purposes.

                  10.  AMENDMENT,  SUPPLEMENT  AND  WAIVER.  Subject  to certain
exceptions,  the Indenture or the Notes may be amended or supplemented  with the
consent of the Holders of a majority in principal amount of the then outstanding
Notes and other series of Securities affected (treating the Notes and such other
series as a single  class),  and any  existing  default or  compliance  with any
provision  of the  Indenture,  the Notes may be waived  with the  consent of the
Holders of a majority  in  principal  amount of the then  outstanding  Notes and
other series of Securities affected (treating the Notes and such other series as
a single  class).  Without the consent of any Holder of a Note, the Indenture or
the  Notes may be  amended  or  supplemented  to cure any  ambiguity,  defect or
inconsistency, to provide for uncertificated Notes in addition to or in place of
certificated  Notes, to provide for the assumption of the Company's  obligations
to Holders of the Notes in case of a merger or consolidation, to make any change
that would provide any additional rights or benefits to the Holders of the Notes
or that does not  adversely  affect the legal rights under the  Indenture of any
such Holder, or to comply with the requirements of the SEC in order to effect or
maintain the qualification of the Indenture under the TIA.

                  11. DEFAULTS AND REMEDIES.  Each of the following  constitutes
an Event of  Default:  (i)  default by the Company in the payment of interest on
the Notes when the same  becomes due and payable  and  default  continues  for a
period of 30 days;  (ii) default by the Company in the payment of the  principal
of or  premium,  if any,  on the Notes when the same  becomes due and payable at
maturity,  upon redemption or otherwise;  (iii) failure by the Company to comply
with  Section  5.01 of the  Indenture;  (iv)  failure by the Company for 30 days
after notice to comply with any of its other  agreements in the Indenture or the
Notes and (v) certain  events of bankruptcy  or  insolvency  with respect to the
Company.  If any Event of Default occurs and is  continuing,  the Trustee or the
Holders of at least 25% in principal  amount of the then  outstanding  Notes and
other series of Securities affected (treating the Notes and such other series as
a single  class) may declare  all the Notes to be due and  payable  immediately.
Notwithstanding  the foregoing,  in the case of an Event of Default arising from
certain  events of  bankruptcy or  insolvency  with respect to the Company,  all
outstanding  Notes will become due and payable without further action or notice.
Holders  of the Notes  may not  enforce  the  Indenture  or the Notes  except as
provided in the Indenture. Subject to certain limitations, Holders of a majority
in principal amount of the then outstanding Notes and other series of Securities
affected (treating the Notes and such other series as a single class) may direct
the Trustee in its exercise of any trust or power. The Trustee may withhold from
Holders  of the  Notes  notice of any  continuing  Default  or Event of  Default
(except a Default or Event of Default  relating to the payment of  principal  or
interest) if it determines that  withholding  notice is in their  interest.  The
Holders  of a  majority  in  aggregate  principal  amount of the Notes and other
series of  Securities  affected  (treating  the Notes and such other series as a

                                       53

<page>

single  class) and other series of Securities  affected  (treating the Notes and
such other series as a single class) then  outstanding  by notice to the Trustee
may on behalf of the Holders of all of the Notes waive any  existing  Default or
Event of Default and its  consequences  under the Indenture  except a continuing
Default or Event of Default in the payment of principal,  interest or premium on
the  Notes.  The  Company is  required  to  deliver  to the  Trustee  annually a
statement regarding  compliance with the Indenture,  and the Company is required
upon  becoming  aware of any  Default  or Event of  Default,  to  deliver to the
Trustee a statement specifying such Default or Event of Default.

                  12.  TRUSTEE  DEALINGS WITH THE COMPANY.  The Trustee,  in its
individual or any other  capacity,  may make loans to, accept deposits from, and
perform services for the Company or its Affiliates,  and may otherwise deal with
the Company or its Affiliates, as if it were not the Trustee.

                  13.  NO  RECOURSE  AGAINST  OTHERS.   No  director,   officer,
employee,  incorporator  or  stockholder of the Company shall have any liability
for any  obligations  of the Company under the Notes or the Indenture or for any
claim  based on, in  respect  of, or by reason  of,  such  obligations  or their
creation.  Each Holder of Notes by accepting a Note waives and releases all such
liability. The waiver and release are part of the consideration for the issuance
of the Notes.

                  14.  AUTHENTICATION.  This  Note  shall  not  be  valid  until
authenticated by the manual signature of the Trustee or an authenticating agent.

                  15. ABBREVIATIONS.  Customary abbreviations may be used in the
name of a Holder or an assignee, such as: TEN COM (= tenants in common), TEN ENT
(=  tenants  by  the  entireties),  JT  TEN  (=  joint  tenants  with  right  of
survivorship and not as tenants in common),  CUST (= Custodian),  and U/G/M/A (=
Uniform Gifts to Minors Act).

                  16. CUSIP NUMBERS. Pursuant to a recommendation promulgated by
the Committee on Uniform  Security  Identification  Procedures,  the Company has
caused  CUSIP  numbers to be printed on the Notes and the  Trustee may use CUSIP
numbers in notices of redemption as a convenience to Holders.  No representation
is made as to the accuracy of such numbers  either as printed on the Notes or as
contained  in any notice of  redemption  and  reliance may be placed only on the
other identification numbers placed thereon.

          The  Company  will  furnish to any Holder  upon  written  request  and
without charge a copy of the Indenture. Requests may be made to:
