         INVESTOR  THAT,  PRIOR TO SUCH  TRANSFER,  FURNISHES  TO THE  TRUSTEE A
         SIGNED  LETTER  CONTAINING  CERTAIN   REPRESENTATIONS   AND  AGREEMENTS
         RELATING  TO THE  RESTRICTIONS  ON  TRANSFER  OF THIS NOTE (THE FORM OF
         WHICH LETTER CAN BE OBTAINED FROM THE  TRUSTEE),  AND, IF SUCH TRANSFER
         IS IN RESPECT OF AN AGGREGATE  PRINCIPAL  AMOUNT OF LESS THAN $250,000,

         LEGEND.  IN  CONNECTION  WITH ANY TRANSFER OF THIS NOTE WITHIN THE TIME
         PERIOD REFERRED TO ABOVE, THE HOLDER MUST CHECK THE APPROPRIATE BOX SET
         FORTH ON THE REVERSE HEREOF RELATING TO THE MANNER OF SUCH TRANSFER AND
         SUBMIT THIS CERTIFICATE TO THE TRUSTEE.  IF THE PROPOSED  TRANSFEREE IS
         AN INSTITUTIONAL  ACCREDITED  INVESTOR,  THE HOLDER MUST, PRIOR TO SUCH
         TRANSFER,  FURNISH TO THE TRUSTEE AND THE COMPANY SUCH  CERTIFICATIONS,
         LEGAL  OPINIONS OR OTHER  INFORMATION  AS EITHER OF THEM MAY REASONABLY
         REQUIRE TO CONFIRM  THAT SUCH  TRANSFER  IS BEING MADE  PURSUANT  TO AN
         EXEMPTION  FROM, OR IN A TRANSACTION  NOT SUBJECT TO, THE  REGISTRATION
         REQUIREMENTS OF THE SECURITIES ACT. AS USED HEREIN, THE TERMS "OFFSHORE
         TRANSACTION," "UNITED STATES" AND "U.S. PERSON" HAVE THE MEANINGS GIVEN
         TO THEM BY  REGULATION  S  UNDER  THE  SECURITIES  ACT.  THE  INDENTURE
         CONTAINS A PROVISION  REQUIRING  THE TRUSTEE TO REFUSE TO REGISTER  ANY
         TRANSFER OF THIS NOTE IN VIOLATION OF THE FOREGOING RESTRICTIONS.

         Each Global Note,  whether or not an Exchange Note, shall also bear the
following legend on the face thereof:

         UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF
         THE  DEPOSITORY  TRUST  COMPANY,  TO  THE  COMPANY  OR  ITS  AGENT  FOR
         REGISTRATION  OF  TRANSFER,  EXCHANGE OR PAYMENT,  AND ANY  CERTIFICATE
         ISSUED IS  REGISTERED IN THE NAME OF CEDE & CO. OR IN SUCH OTHER ENTITY
         AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST
         COMPANY (AND ANY PAYMENT  HEREON IS MADE TO CEDE & CO. OR TO SUCH OTHER
         ENTITY  AS  IS  REQUESTED  BY  AN  AUTHORIZED   REPRESENTATIVE  OF  THE
         DEPOSITORY TRUST COMPANY), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR
         VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL SINCE THE REGISTERED
         OWNER HEREOF, CEDE & CO., HAS AN INTEREST HEREIN.

         THIS  SECURITY IS A GLOBAL NOTE WITHIN THE MEANING OF THE INDENTURE AND
         IS  REGISTERED  IN THE  NAME OF  CEDE & CO.  THIS  SECURITY  MAY NOT BE
         EXCHANGED  IN  WHOLE  OR IN  PART  FOR A  SECURITY  REGISTERED,  AND NO
         TRANSFERS OF THIS GLOBAL NOTE IN WHOLE OR IN PART MAY BE REGISTERED, IN
         THE NAME OF ANY PERSON OTHER THAN NOMINEES OF CEDE & CO. OR A SUCCESSOR
         THEREOF OR SUCH  SUCCESSOR'S  NOMINEE AND TRANSFERS OF PORTIONS OF THIS
         GLOBAL NOTE SHALL BE LIMITED TO TRANSFERS  MADE IN ACCORDANCE  WITH THE
         RESTRICTIONS SET FORTH IN SECTION 2.08 OF THE INDENTURE.

         SECTION 2.03. Execution,  Authentication and Denominations.  Subject to
                       --------------------------------------------
Article Four and applicable law, the aggregate  principal  amount of Notes which
may be authenticated and delivered under this Indenture is unlimited.  The Notes
shall be  executed  by two  Officers  of the

                                     - 9 -


Company.  The  signature  of these  Officers on the Notes may be by facsimile or
manual signature in the name and on behalf of the Company.

         If an Officer whose  signature is on a Note no longer holds that office
at the time the Trustee or authenticating agent authenticates the Note, the Note
shall be valid nevertheless.

         A Note shall not be valid  until the  Trustee or  authenticating  agent
manually  signs the  certificate  of  authentication  on the Note. The signature
shall be  conclusive  evidence that the Note has been  authenticated  under this
Indenture.

         At any  time  and  from  time  to  time  after  the  execution  of this
Indenture,  the  Trustee or an  authenticating  agent  shall  upon  receipt of a
Company Order  authenticate for original issue Notes in the aggregate  principal
amount  specified  in such Company  Order;  provided  that the Trustee  shall be
entitled to receive an  Officers'  Certificate  and an Opinion of Counsel of the
Company in  connection  with such  authentication  of Notes.  Such Company Order
shall specify the amount of Notes to be authenticated  and the date on which the
original  issue of Notes is to be  authenticated  and, in case of an issuance of
Notes  pursuant  to  Section  2.14,  shall  certify  that  such  issuance  is in
compliance with Article Four.

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

         The Notes shall be issuable only in registered form without coupons and
only in denominations  of $1,000 in principal  amount and any integral  multiple
thereof.

         SECTION 2.04. Registrar and Paying Agent. The Company shall maintain an
                       --------------------------
office or agency where Notes may be presented  for  registration  of transfer or
for exchange (the "Registrar"), an office or agency where Notes may be presented
                   ---------
for  payment  (the  "Paying  Agent") and an office or agency  where  notices and
                     -------------
demands to or upon the Company in respect of the Notes and this Indenture may be
served,  which shall be in the Borough of Manhattan,  The City of New York.  The
Company  shall cause the  Registrar to keep a register of the Notes and of their
transfer and exchange (the "Security Register").  The Security Register shall be
                            -----------------
in written form or any other form capable of being  converted  into written form
within a reasonable time. The Company may have one or more Co-Registrars and one
or more additional Paying Agents.

         The Company shall enter into an appropriate  agency  agreement with any
Agent  not a  party  to  this  Indenture.  The  agreement  shall  implement  the
provisions of this Indenture  that relate to such Agent.  The Company shall give
prompt  written  notice to the Trustee of the name and address of any such Agent
and any change in the address of such Agent.  If the Company fails to maintain a
Registrar,  Paying Agent  and/or  agent for service of notices and demands,  the
Trustee  shall act as such  Registrar,  Paying Agent and/or agent for service of
notices and  demands.  The Company may remove any Agent upon  written  notice to
such Agent and the Trustee; provided that no such removal shall become effective
until (i) the acceptance of an appointment by a successor Agent to such Agent as
evidenced by an  appropriate  agency

                                     - 10 -


agreement  entered into by the Company and such successor Agent and delivered to
the Trustee or (ii)  notification to the Trustee that the Trustee shall serve as
such Agent until the  appointment of a successor Agent in accordance with clause
(i) of this proviso. The Company, any Subsidiary of the Company or any Affiliate
of any of them may act as Paying Agent, Registrar or Co-Registrar,  and/or agent
for service of notice and demands.

         The Company initially appoints the Trustee as Registrar,  Paying Agent,
authenticating  agent and agent for service of notice and  demands.  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 Holders and shall  otherwise
comply with TIA Section 312(a). If the Trustee is not the Registrar, the Company
shall  furnish to the  Trustee as of each Record Date and at such other times as
the Trustee may  reasonably  request the names and  addresses of Holders as they
appear in the Security  Register,  including the aggregate  principal  amount of
Notes held by each Holder.

         SECTION 2.05. Paying Agent to Hold Money in Trust. Not later than 10:00
                       -----------------------------------
a.m.  (New York City time) on each due date of any  principal  of or interest on
any Notes,  the Company shall deposit with the Paying Agent money in immediately
available  funds  sufficient to pay such principal and interest so becoming due.
The Company  shall  require each Paying Agent other than the Trustee to agree in
writing  that such  Paying  Agent  shall  hold in trust for the  benefit  of the
Holders or the  Trustee  all money held by the Paying  Agent for the  payment of
principal of and interest on the Notes  (whether  such money has been paid to it
by the Company or any other  obligor on the Notes),  and such Paying Agent shall
promptly  notify the Trustee of any default by the Company (or any other obligor
on the Notes) in making any such payment.  The Company at any time may require a
Paying  Agent to pay all money held by it to the  Trustee  and  account  for any
funds  disbursed,  and the Trustee may at any time during the continuance of any
payment  default,  upon written  request to a Paying Agent,  require such Paying
Agent to pay all money held by it to the  Trustee  and to account  for any funds
disbursed.  Upon doing so, the Paying Agent shall have no further  liability for
the money so paid over to the Trustee.  If the Company or any  Subsidiary of the
Company or any  Affiliate of any of them acts as Paying  Agent,  it will,  on or
before each due date of any principal of or interest on the Notes, segregate and
hold in a  separate  trust fund for the  benefit  of the  Holders a sum of money
sufficient  to pay such  principal or interest so becoming due until such sum of
money shall be paid to such Holders or otherwise disposed of as provided in this
Indenture, and will promptly notify the Trustee of its action or failure to act.

         SECTION  2.06.  Transfer and  Exchange.  The Notes are issuable only in
                         ----------------------
registered form. A Holder may transfer a Note only by written application to the
Registrar  stating the name of the proposed  transferee and otherwise  complying
with the terms of this Indenture.  No such transfer shall be effected until, and
such  transferee  shall  succeed  to the  rights of a Holder  only  upon,  final
acceptance  and  registration  of the transfer by the  Registrar in the Security
Register.  Prior to the  registration  of any  transfer  by a Holder as provided
herein,  the Company,  the Trustee and any agent of the Company  shall treat the
person  in whose  name the  Note is  registered  as the  owner  thereof  for all
purposes whether or not the Note shall be overdue,  and none of the Company, the
Trustee  or any  such  agent  shall  be  affected  by  notice  to the  contrary.
Furthermore,  any Holder of a Global Note shall,  by  acceptance  of such Global
Note,  agree that  transfers of beneficial  interests in such Global Note may be
effected  only  through a book  entry  system  maintained  by the Holder of such
Global Note (or its agent) and that  ownership of a  beneficial  interest in the

                                     - 11 -


Note shall be required to be reflected in a book entry. When Notes are presented
to the Registrar or a Co-Registrar with a request to register the transfer or to
exchange  them  for an equal  principal  amount  of  Notes  of other  authorized
denominations (including an exchange of Notes for Exchange Notes), the Registrar
shall   register  the  transfer  or  make  the  exchange  as  requested  if  its
requirements  for such  transactions are met (including that such Notes are duly
endorsed or accompanied by a written instrument of transfer in form satisfactory
to the  Trustee  and  Registrar  duly  executed  by the Holder  thereof or by an
attorney who is authorized in writing to act on behalf of the Holder);  provided
that no exchanges of Notes for Exchange  Notes shall occur until a  Registration
Statement  shall have been  declared  effective by the  Commission  and that any
Notes that are exchanged  for Exchange  Notes shall be cancelled by the Trustee.
To permit  registrations  of transfers and exchanges,  the Company shall execute
and the Trustee shall authenticate Notes at the Registrar's  request. No service
charge shall be made for any  registration of transfer or exchange of the Notes,
but the Company may require  payment of a sum  sufficient  to cover any transfer
tax or similar  governmental charge payable in connection  therewith (other than
any such  transfer  taxes or other  similar  governmental  charge  payable  upon
exchanges pursuant to Section 2.11 or 9.05).

         SECTION 2.07. Book-Entry Provisions for Global Notes.
                       --------------------------------------

         (a) The U.S. Global Notes and Offshore Global Notes initially shall (i)
be registered in the name of the Depositary for such Global Notes or the nominee
of such  Depositary,  (ii) be  delivered  to the Trustee as  custodian  for such
Depositary and (iii) bear legends as set forth in Section 2.02.

         Members of, or participants in, the Depositary  ("Agent Members") shall
have no rights  under this  Indenture  with  respect to any Global  Note held on
their behalf by the Depositary,  or the Trustee as its custodian,  or under such
Global Note, and the  Depositary may be treated by the Company,  the Trustee and
any agent of the  Company or the  Trustee as the  absolute  owner of such Global
Note for all purposes whatsoever.  Notwithstanding the foregoing, nothing herein
shall  prevent  the  Company,  the  Trustee  or any agent of the  Company or the
Trustee,  from  giving  effect  to any  written  certification,  proxy  or other
authorization  furnished by the Depositary or impair,  as between the Depositary
and its Agent  Members,  the  operation of  customary  practices  governing  the
exercise of the rights of a holder of any Note.

         (b)  Transfers  of a Global Note shall be limited to  transfers of such
Global Note in whole,  but not in part,  to the  Depositary,  its  successors or
their respective nominees. Interests of beneficial owners in Global Notes may be
transferred  in accordance  with the rules and  procedures of the Depositary and
the  provisions of Section 2.08. In addition,  U.S.  Physical Notes and Offshore
Physical Notes shall be  transferred  to all  beneficial  owners in exchange for
their  beneficial  interests in the U.S.  Global  Notes or the  Offshore  Global
Notes, as the case may be, if (i) the Depositary notifies the Company that it is
unwilling or unable to continue as Depositary  for the U.S.  Global Notes or the

         (c)  Any  beneficial  interest  in one  of the  Global  Notes  that  is
transferred to a person who takes delivery in the form of an interest in another
Global Note will, upon transfer, cease to be an interest in such Global Note and
become an interest in such other Global Note and,  accordingly,  will thereafter
be subject to all transfer restrictions, if any, and other procedures applicable
to beneficial interests in such other Global Note for as long as it remains such
an interest.

         (d) In  connection  with any  transfer  of a portion of the  beneficial
interests in a Global Note to  beneficial  owners  pursuant to paragraph  (b) of
this Section 2.07, the Registrar shall reflect on its books and records the date
and a decrease in the principal amount of such Global Note in an amount equal to
the  principal  amount of the  beneficial  interest  in such  Global  Note to be
transferred,  and the Company shall execute,  and the Trustee shall authenticate
and deliver,  one or more U.S. Physical Notes or Offshore Physical Notes, as the
case may be, of like tenor and amount.

         (e) In  connection  with the  transfer of the U.S.  Global Notes or the
Offshore Global Notes, in whole, to beneficial  owners pursuant to paragraph (b)
of this Section 2.07,  the U.S.  Global Notes or Offshore  Global Notes,  as the
case may be, shall be deemed to be surrendered to the Trustee for  cancellation,
and the Company shall execute,  and the Trustee shall  authenticate and deliver,
to each  beneficial  owner  identified  by the  Depositary  in exchange  for its
beneficial  interest in the U.S.  Global Notes or Offshore  Global Notes, as the
case may be,  an equal  aggregate  principal  amount of U.S.  Physical  Notes or
Offshore Physical Notes, as the case may be, of authorized denominations.

         (f) Any U.S. Physical Note delivered in exchange for an interest in the
U.S.  Global Notes  pursuant to  paragraph  (b), (d) or (e) of this Section 2.07
shall,  except as otherwise  provided by paragraph (h) of Section 2.08, bear the
legend regarding transfer restrictions  applicable to the U.S. Physical Note set
forth in Section 2.02.

         (g) Any Offshore Physical Note delivered in exchange for an interest in
the Offshore  Global Notes pursuant to paragraph (b), (d) or (e) of this Section
2.07 shall,  except as otherwise provided by paragraph (h) of Section 2.08, bear
the legend regarding transfer  restrictions  applicable to the Offshore Physical
Note set forth in Section 2.02.

         (h) The  registered  holder  of a Global  Note may  grant  proxies  and
otherwise  authorize  any person,  including  Agent Members and persons that may
hold  interests  through  Agent  Members,  to take any action  which a Holder is
entitled to take under this Indenture or the Notes.

         SECTION 2.08. Special Transfer  Provisions.  Unless and until a Note is
                       ----------------------------

                           (i) The Registrar  shall register the transfer of any
                  Note,  whether  or not such Note bears the  Private  Placement
                  Legend, if (x) the requested transfer is after the time period
                  referred to in Rule 144(k) under the Securities Act or (y) the
                  proposed  transferee  has  delivered  to the  Registrar  (A) a
                  certificate  substantially in the form of Exhibit C hereto and
                  (B) if the  aggregate  principal  amount  of the  Notes  being

                  acceptable  to the Company that such transfer is in compliance
                  with the Securities Act.

                           (ii) If the  proposed  transferor  is an Agent Member
                  holding a beneficial  interest in the U.S. Global Notes,  upon
                  receipt  by  the  Registrar  of (x)  the  documents,  if  any,
                  required by paragraph (i) above and (y) instructions  given in
                  accordance   with  the   Depositary's   and  the   Registrar's
                  procedures,  the  Registrar  shall  reflect  on its  books and
                  records the date and a decrease in the principal amount of the
                  U.S.  Global Notes in an amount equal to the principal  amount
                  of the  beneficial  interest  in the U.S.  Global  Notes to be
                  transferred,  and the Company shall  execute,  and the Trustee

                      -----------------
         with respect to the registration of any proposed  transfer of a Note to
         a QIB (excluding Non-U.S. Persons):

                           (i) If the  Note to be  transferred  consists  of (x)
                  either  Offshore  Physical  Notes  prior to the removal of the
                  Private Placement Legend or U.S. Physical Notes, the Registrar
                  shall  register the transfer if such transfer is being made by

                  the form of Note stating, or has otherwise advised the Company
                  and the  Registrar in writing,  that the sale has been made in
                  compliance  with the  provisions  of Rule 144A to a transferee
                  who has signed the  certification  provided for on the form of
                  Note  stating,  or has  otherwise  advised the Company and the
                  Registrar in writing,  that it is purchasing  the Note for its
                  own account or an account  with  respect to which it exercises
                  sole investment discretion and that it and any such account is

                  sale  to it is  being  made  in  reliance  on  Rule  144A  and
                  acknowledges  that it has received such information  regarding
                  the Company as it has  requested  pursuant to Rule 144A or has
                  determined  not to  request  such  information  and that it is
                  aware  that the  transferor  is  relying  upon  its  foregoing
                  representations   in  order  to  claim  the   exemption   from
                  registration  provided  by Rule 144A or (y) an interest in the
                  U.S.  Global  Notes,  the  transfer  of such  interest  may be
                  effected only through the book-entry  system maintained by the
                  Depositary.

                           (ii) If the proposed  transferee  is an Agent Member,
                  and  the  Note to be  transferred  consists  of U.S.  Physical

                  Registrar  shall reflect on its books and records the date and
                  an increase in the principal amount of U.S. Global Notes in an
                  amount  equal to the  principal  amount  of the U.S.  Physical

                                     - 14 -


                  Notes to be transferred, and the Trustee shall cancel the U.S.
                  Physical Notes so transferred.

                  (c)  Transfers of  Interests  in the Offshore  Global Notes or
                       ---------------------------------------------------------
         Offshore  Physical  Notes.  The following  provisions  shall apply with
         -------------------------
         respect to any  transfer  of  interests  in  Offshore  Global  Notes or
         Offshore Physical Notes:

                           (i) prior to the  removal  of the  Private  Placement
                  Legend from the  Offshore  Global  Notes or Offshore  Physical
                  Notes pursuant to Section 2.02, the Registrar  shall refuse to
                  register  such  transfer  unless such  transfer  complies with
                  Section 2.08(b) or Section 2.08(d), as the case may be, and

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

                  (d) Transfers to Non-U.S.  Persons at Any Time.  The following
                      ------------------------------------------
         provisions  shall  apply with  respect to any  transfer  of a Note to a
         Non-U.S. Person:

                           (i)  The  Registrar   shall   register  any  proposed
                  transfer to any Non-U.S.  Person if the Note to be transferred
                  is a U.S.  Physical Note or an interest in U.S.  Global Notes,
                  upon  receipt of a  certificate  substantially  in the form of
                  Exhibit D hereto from the proposed transferor.

                           (ii)  (a)  If the  proposed  transferor  is an  Agent
                  Member holding a beneficial interest in the U.S. Global Notes,
                  upon receipt by the  Registrar of (x) the  documents,  if any,
                  required by paragraph (ii) and (y)  instructions in accordance
                  with the  Depositary's  and the  Registrar's  procedures,  the
                  Registrar  shall reflect on its books and records the date and
                  a decrease in the principal amount of the U.S. Global Notes in
                  an amount  equal to the  principal  amount  of the  beneficial
                  interest in the U.S. Global Notes to be  transferred,  and (b)
                  if the proposed transferee is an Agent Member, upon receipt by
                  the Registrar of  instructions  given in  accordance  with the
                  Depositary's  and the  Registrar's  procedures,  the Registrar
                  shall  reflect  on its  books  and  records  the  date  and an
                  increase in the principal  amount of the Offshore Global Notes
                  in an  amount  equal  to the  principal  amount  of  the  U.S.
                  Physical Notes or the U.S.  Global Notes,  as the case may be,
                  to be  transferred,  and the Trustee shall cancel the Physical
                  Note,  if any, so  transferred  or decrease  the amount of the
                  U.S. Global Notes.

                  (e) Private Placement Legend.  Upon the transfer,  exchange or
                      ------------------------
         replacement  of Notes not  bearing the Private  Placement  Legend,  the
         Registrar  shall deliver  Notes that do not bear the Private  Placement
         Legend. Upon the transfer, exchange or replacement of Notes bearing the
         Private Placement  Legend,  the Registrar shall deliver only Notes that
         bear the Private  Placement  Legend  unless (i) the  Private  Placement
         Legend is no longer  required by Section 2.02,  (ii) the  circumstances
         contemplated by paragraph (a)(i)(x) of this Section 2.08 exist or (iii)
         there is  delivered to the  Registrar an Opinion of Counsel  reasonably
         satisfactory  to the Company and the Trustee to the effect that neither
         such

                                     - 15 -


         legend nor the related  restrictions  on transfer are required in order
         to maintain compliance with the provisions of the Securities Act.

                  (f) General. By its acceptance of any Note bearing the Private
                      -------
         Placement  Legend,   each  Holder  of  such  a  Note  acknowledges  the
         restrictions  on transfer of such Note set forth in this  Indenture and
         in the Private  Placement  Legend and agrees that it will transfer such
         Note  only as  provided  in this  Indenture.  The  Registrar  shall not
         register a transfer of any Note unless such transfer  complies with the
         restrictions on transfer of such Note set forth in this  Indenture.  In
         connection  with any  transfer  of  Notes,  each  Holder  agrees by its
         acceptance  of the Notes to furnish the  Registrar  or the Company such
         certifications,  legal opinions or other  information as either of them
         may  reasonably  require to confirm  that such  transfer  is being made
         pursuant to an exemption  from,  or a  transaction  not subject to, the
         registration  requirements  of the  Securities  Act;  provided that the
         Registrar  shall  not be  required  to  determine  (but  may  rely on a
         determination  made by the Company with respect to) the  sufficiency of
         any such certifications, legal opinions or other information.

         The  Registrar  shall retain  copies of all letters,  notices and other
written  communications  received pursuant to Section 2.07 or this Section 2.08.
The Company shall have the right to inspect and make copies of all such letters,
notices or other written  communications  at any reasonable time upon the giving
of reasonable written notice to the Registrar.

         SECTION 2.09.  Replacement Notes. If a mutilated Note is surrendered to
                        -----------------
the Trustee or if the Holder  claims that the Note has been lost,  destroyed  or
wrongfully  taken,  then, in the absence of notice to the Company or the Trustee
that such Note has been  acquired by a bona fide  purchaser,  the Company  shall
issue and the Trustee shall  authenticate  a replacement  Note of like tenor and
principal  amount  and  bearing  a  number  not  contemporaneously  outstanding;
provided that the  requirements of this Section 2.09 are met. If required by the
Trustee or the Company,  an indemnity  bond must be furnished that is sufficient
in the judgment of both the Trustee and the Company to protect the Company,  the
Trustee  or any  Agent  from any loss  that any of them may  suffer if a Note is
replaced.  The Company may charge such Holder for its  expenses and the expenses
of the Trustee in replacing a Note. In case any such mutilated,  lost, destroyed
or wrongfully  taken Note has become or is about to become due and payable,  the
Company  in its  discretion  may pay such Note  instead of issuing a new Note in
replacement thereof.

         Every  replacement Note is an additional  obligation of the Company and
shall be entitled to the benefits of this Indenture.

         SECTION 2.10.  Outstanding Notes. Notes outstanding at any time are all
                        -----------------
Notes that have been  authenticated by the Trustee except for those cancelled by
it, those delivered to it for  cancellation  and those described in this Section
2.10 as not outstanding.

         If a Note is  replaced  pursuant  to  Section  2.09,  it  ceases  to be
outstanding  unless  and  until  the  Trustee  and  the  Company  receive  proof
satisfactory to them that the replaced Note is held by a bona fide purchaser.

                                     - 16 -


         If the Paying  Agent  (other  than the Company or an  Affiliate  of the
Company)  holds on the Maturity  Date money  sufficient  to pay Notes payable on
that date,  then on and after that date such Notes cease to be  outstanding  and
interest on them shall cease to accrue.

         A Note does not cease to be  outstanding  because the Company or one of
its Affiliates holds such Note, provided,  however,  that in determining whether
the Holders of the  requisite  principal  amount of the  outstanding  Notes have
given any request, demand,  authorization,  direction, notice, consent or waiver
hereunder, Notes owned by the Company or any other obligor upon the Notes or any
Affiliate  of the  Company or of such other  obligor  shall be  disregarded  and
deemed not to be  outstanding,  except that, in determining  whether the Trustee
shall be  protected  in relying upon any such  request,  demand,  authorization,
direction,  notice, consent or waiver, only Notes which a Responsible Officer of
the Trustee has actual  knowledge to be so owned shall be so disregarded.  Notes
so owned which have been pledged in good faith may be regarded as outstanding if
the pledgee  establishes to the  satisfaction of the Trustee the pledgee's right
so to act with  respect to such Notes and that the pledgee is not the Company or
any other  obligor  upon the Notes or any  Affiliate  of the  Company or of such
other obligor.

         SECTION 2.11.  Temporary  Notes.  Until  definitive Notes are ready for
                        ----------------
delivery, the Company may prepare and execute and the Trustee shall authenticate
temporary  Notes.  Temporary  Notes  shall  be  substantially  in  the  form  of
definitive  Notes but may have  insertions,  substitutions,  omissions and other
variations  determined to be appropriate by the Officers executing the temporary
Notes,  as evidenced by their  execution of such temporary  Notes.  If temporary
Notes are issued, the Company will cause definitive Notes to be prepared without
unreasonable  delay.  After the preparation of definitive  Notes,  the temporary
Notes shall be exchangeable for definitive Notes upon surrender of the temporary
Notes at the  office  or  agency  of the  Company  designated  for such  purpose
pursuant to Section  4.02,  without  charge to the Holder.  Upon  surrender  for
cancellation  of any one or more  temporary  Notes the Company shall execute and
the Trustee shall authenticate and deliver in exchange therefor a like principal
amount of definitive Notes of authorized denominations.  Until so exchanged, the
temporary  Notes shall be entitled to the same benefits  under this Indenture as
definitive Notes.

         SECTION 2.12. Cancellation.  The Company at any time may deliver to the
                       ------------
Trustee  for  cancellation  any Notes  previously  authenticated  and  delivered
hereunder which the Company may have acquired in any manner whatsoever,  and may
deliver to the  Trustee  for  cancellation  any Notes  previously  authenticated
hereunder  which the  Company  has not issued and sold.  The  Registrar  and the
Paying  Agent shall  forward to the Trustee  any Notes  surrendered  to them for
transfer,  exchange or payment.  The Trustee shall cancel all Notes  surrendered
for transfer,  exchange,  payment or  cancellation  and shall dispose of them in
accordance with its normal procedure.

         SECTION 2.13.  CUSIP Numbers.  The Company in issuing the Notes may use
                        -------------
"CUSIP",  "CINS" or "ISIN"  numbers (if then  generally in use), and the Company
and the Trustee shall use CUSIP,  CINS or ISIN  numbers,  as the case may be, in
notices of exchange as a convenience  to Holders;  provided that any such notice
shall state that no representation is made as to the correctness of such numbers
either as printed on the Notes or as  contained  in any notice of  exchange  and
that reliance may be placed only on the other identification  numbers printed on

                                     - 17 -


the Notes.  The  Company  shall  promptly  notify  the  Trustee of any change in
"CUSIP", "CINS" or "ISIN" numbers for the Notes.

         SECTION 2.14. Issuance of Additional Notes. The Company may, subject to
                       ----------------------------
Article Four of this Indenture and applicable law, issue  additional Notes under
this  Indenture.  The Notes issued on the Closing Date and any additional  Notes
subsequently  issued shall be treated as a single  class for all purposes  under
this Indenture.

                                  ARTICLE THREE

                                   REDEMPTION

         SECTION 3.01.  Right of Redemption.  The Notes are not redeemable prior
                        -------------------
to the Maturity Date.

ARTICLE Four

                                    COVENANTS

         SECTION 4.01.  Payment of Notes. The Company shall pay the principal of
                        ----------------
and  interest on the Notes on the dates and in the manner  provided in the Notes
and this Indenture.  An installment of principal or interest shall be considered
paid on the date due if the Trustee or Paying Agent  (other than the Company,  a
Subsidiary  of the Company or any  Affiliate  of any of them) holds on that date
money  designated for and sufficient to pay the  installment.  If the Company or
any  Subsidiary  of the Company or any  Affiliate  of any of them acts as Paying
Agent,  an installment of principal or interest shall be considered  paid on the
due date if the entity acting as Paying Agent complies with the last sentence of
Section 2.05. As provided in Section 6.10, upon any bankruptcy or reorganization
procedure relative to the Company,  the Trustee shall serve as the Paying Agent,
if any, for the Notes.

         SECTION 4.02.  Maintenance  of Office or Agency.  So long as any of the
                        --------------------------------
Notes shall  remain  outstanding,  the Company  will  maintain in the Borough of
Manhattan,  The  City  of New  York an  office  or  agency  where  Notes  may be
surrendered  for  registration of transfer or exchange or for  presentation  for
payment  and where  notices and demands to or upon the Company in respect of the
Notes and this  Indenture  may be served.  The Company will 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 address of the Trustee set forth in Section 11.02.

         The  Company  may also from time to time  designate  one or more  other
offices or agencies where the Notes may be presented or  surrendered  for any or
all such purposes and may from time to time rescind such designations;  provided
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

                                     - 18 -


notice to the Trustee of any such designation or rescission and of any change in
the location of any such other office or agency.

- ----------
will not, directly or indirectly,  create, issue, assume, incur or guarantee any
indebtedness  for money borrowed which is secured by a mortgage,  pledge,  lien,
security  interest or other  encumbrance  of any nature on any of the present or
future common stock of any  Significant  Subsidiary (or any company,  other than
the Company,  having direct or indirect control of any Significant  Subsidiary),
which common stock is directly or  indirectly  owned by the Company,  unless the
Notes (together with, if the Company so determines,  any other  indebtedness for
money  borrowed of the Company then existing or thereafter  created which is not
subordinate to the Notes) shall be secured  equally and ratably with (or, at the
option of the  Company,  prior to) such  other  secured  indebtedness  for money
borrowed so long as such indebtedness shall be secured.

         SECTION 4.04. Compliance Certificates. The Company shall deliver to the
                       -----------------------

Certificate signed by the Company's chief financial officer, principal executive
officer or principal  accounting officer stating whether or not the signers have
knowledge  of any  Default or Event of  Default.  If any of the  Officers of the
Company  signing such  certificate  has  knowledge of such a Default or Event of
Default,  the Officers'  Certificate shall describe any such Default or Event of
Default and the nature thereof.

         SECTION 4.05. Interest Rate Adjustment.
                       ------------------------


         (a) In the event  that  either  Moody's  or S&P  downgrades  the credit
rating ascribed to the Company's  senior  unsecured debt below A3 in the case of
Moody's or below A- in the case of S&P, the  interest  rate payable on the Notes
will be  increased  by 0.25%  for  each  Rating  Category  downgrade  below  the
applicable level by each rating agency.

         (b) If following an event described in Section 4.05(a),  Moody's or S&P
subsequently  increases the rating  ascribed to the Company's  senior  unsecured
debt, then the interest rate payable on the Notes will be decreased by 0.25% for
each Rating Category upgrade by either rating agency, provided, however, that in
no event  will the  interest  rate  payable on the Notes be reduced to below the
initial interest rate as a result of this Section 4.05(b).

         (c) Any such  interest  rate  increase  or  decrease  will take  effect
commencing  on the  Interest  Payment  Date next  following  the related  rating
downgrade or upgrade, as the case may be, subject to the further adjustments and
limitations set forth under Section 4.05(b).  There is no limit to the number of
times the interest rate payable on the Notes can be adjusted.

                       ---------------------------
particular instance to comply with any term, provision or condition set forth in
Section  4.03 if before the time for such  compliance  the Holders of at least a
majority in aggregate  principal  amount of the Notes  shall,  by action of such
Holders,  either  waive such  compliance  in such  instance or  generally  waive
compliance  with such term,  provision  or  condition,  but no such waiver shall
extend to or affect such term,  provision or condition,  except to the extent so
expressly waived, and, until such waiver shall become effective, the obligations
of the  Company  and the  duties of the  Trustee  in  respect  of any such term,
provision or condition shall remain in full force and effect.

         SECTION 5.01.  When Company May Merge,  Etc. So long as any Notes shall
                        ----------------------------

which  leases,  the  properties  and assets of the Company  substantially  as an
entirety  shall be a corporation  organized  and existing  under the laws of the
United  States of America,  any State  thereof or the  District of Columbia  and
shall  expressly  assume,  by an  indenture  supplemental  hereto,  executed and
delivered to the Trustee,  the due and punctual  payment of the principal of and
interest on the Notes and the performance of every covenant of this Indenture on
the part of the Company to be performed or observed;

         (b)  immediately  after giving effect to such  transaction and treating
any indebtedness  which becomes an obligation of the Company as a result of such
transaction  as  having  been  incurred  by the  Company  at the  time  of  such
transaction,  no Event of Default,  and no event which, after notice or lapse of
time or both,  would  become an Event of  Default,  shall have  happened  and be
continuing;

         (c) if, as a result of any such  consolidation  or merger or such sale,
conveyance,  transfer,  lease or other disposition,  properties or assets of the
Company would become subject to a mortgage,  pledge,  lien, security interest or
other  encumbrance of any nature which would not be permitted by this Indenture,
the Company or such successor  corporation or such Person,  firm or corporation,
as the case may be, shall take such steps as shall be necessary  effectively  to
secure  the Notes  (together  with,  if the  Company  so  determines,  any other
indebtedness  for money  borrowed of the  Company  then  existing or  thereafter
created which is not  subordinate to the Notes) equally and ratably with (or, at
the option of the Company, prior to) all indebtedness secured thereby; and

         (d) the Company has  delivered to the Trustee an Officers'  Certificate
and an Opinion of Counsel,  each stating that such consolidation,  merger, sale,
conveyance,  transfer,  lease  or

                                     - 20 -


other  disposition  and, if a  supplemental  indenture is required in connection
with such transaction, such supplemental indenture comply with this Article Five
and  that  all  conditions  precedent  herein  provided  for  relating  to  such
transaction have been complied with.

be substituted for, and may exercise every right and power of, the Company under
this Indenture  with the same effect as if such successor  Person had been named
as the Company herein;  provided that the Company shall not be released from its
obligation  to pay the  principal  of or  interest on the Notes in the case of a
lease of all or substantially all of its property and assets.

                                   ARTICLE SIX

                              DEFAULT AND REMEDIES

         SECTION  6.01.  Events of Default.  Any of the  following  events shall
                         -----------------
constitute an "Event of Default" hereunder:
               ----------------

         (a) default in the payment of the  principal of any of the Notes as and
when the same shall become due and payable either at maturity, by declaration or
otherwise; or

         (b) default in the payment of any installment of interest on any of the
Notes as and when the same shall become due and payable, and continuance of such
default for a period of 30 days; or

         (c) failure on the part of the  Company  duly to observe or perform any
other  of the  covenants  or  agreements  on the  part  of the  Company  in this
Indenture  applicable  to the Notes  for a period  of 90 days  after the date on
which written notice of such failure,  specifying such failure and requiring the
Company to remedy the same and stating that such notice is a "Notice of Default"
hereunder,  shall  have been  given to the  Company  by the  Trustee,  or to the
Company and the Trustee by the  Holders of at least 25% in  aggregate  principal
amount of the Notes at the time outstanding; or

         (d) a court having jurisdiction in the premises shall enter a decree or
order for  relief in respect of the  Company  in an  involuntary  case under any
applicable  bankruptcy,  insolvency  or other  similar law now or  hereafter  in
effect,  or appointing a receiver,  liquidator,  assignee,  custodian,  trustee,
sequestrator (or similar official) of the Company or for any substantial part of
its property,  or ordering the winding-up or liquidation of its affairs and such
decree or order shall remain unstayed and in effect for a period of 90 days; or

         (e) the Company shall  commence a voluntary  case under any  applicable
bankruptcy, insolvency or other similar law now or hereafter in effect, or shall
consent  to the entry of any order for relief in an  involuntary  case under any
such law,  or shall  consent to the  appointment  of or taking  possession  by a
receiver,  liquidator,  assignee, trustee,  custodian,  sequestrator (or

                                     - 21 -


similar official) of the Company or for any substantial part of its property, or
shall make any general assignment for the benefit of creditors.

         SECTION 6.02. Acceleration. If an Event of Default (other than an Event
                       ------------
of  Default  specified  in clause (d) or (e) of Section  6.01 that  occurs  with
respect to the  Company)  occurs and is  continuing  under this  Indenture,  the
Trustee or the  Holders  of at least 25% in  aggregate  principal  amount of the
Notes then outstanding,  by written notice to the Company (and to the Trustee if
such  notice is given by the  Holders),  may,  and the Trustee at the request of
such Holders shall,  declare the principal of and accrued and unpaid interest on
all the Notes to be immediately due and payable, any provision of this Indenture
or  the  Notes  to  the  contrary   notwithstanding.   Upon  a  declaration   of
acceleration,   such  principal  and  accrued  and  unpaid   interest  shall  be
immediately  due and  payable.  In the event of a  declaration  of  acceleration
because an Event of Default set forth in clause (c) of Section 6.01 has occurred
and is continuing,  such  declaration  of  acceleration  shall be  automatically
rescinded and annulled if the event of default  triggering such Event of Default
pursuant  to clause (c) shall be  remedied  or cured by the Company or waived by
the Holders within 60 days after the  declaration of  acceleration  with respect
thereto.  If an Event of Default  specified in clause (d) or (e) of Section 6.01
occurs  with  respect to the  Company,  the  principal  and  accrued  and unpaid
interest  on  the  Notes  then  outstanding  shall  ipso  facto  become  and  be
immediately  due and payable without any declaration or other act on the part of
the Trustee or any Holder.

         At any time  after  such  declaration  of  acceleration,  but  before a
judgment  or decree for the  payment of the money due has been  obtained  by the
Trustee,  the  Holders  of at  least  a  majority  in  principal  amount  of the
outstanding Notes by written notice to the Company and to the Trustee, may waive
all past Defaults and rescind and annul a declaration  of  acceleration  and its
consequences  if (a) the  Company has paid or  deposited  with the Trustee a sum
sufficient to pay (i) all sums paid or advanced by the Trustee hereunder and the
reasonable  compensation,  expenses,  disbursements and advances of the Trustee,
its agents and counsel,  (ii) all overdue  interest on all Notes,  and (iii) the
principal of any Notes that have become due otherwise  than by such  declaration
or  occurrence  of  acceleration  and  interest  thereon at the rate  prescribed
therefor  by such Notes,  (b) all  existing  Events of  Default,  other than the
non-payment  of the  principal  of and accrued and unpaid  interest on the Notes
that have become due solely by such declaration of acceleration, have been cured
or waived and (c) the rescission  would not conflict with any judgment or decree
of a court of competent jurisdiction.

         SECTION  6.03.  Other  Remedies.  If an Event of Default  occurs and is
                         ---------------
continuing,  the Trustee may, and at the  direction of the Holders of at least a
majority  in  principal  amount  of the  outstanding  Notes  shall,  pursue  any
available  remedy by  proceeding  at law or in equity to collect  the payment of
principal  of or  interest  on the Notes or to enforce  the  performance  of any
provision of the Notes or this Indenture.

         The Trustee may maintain a  proceeding  even if it does not possess any
of the Notes or does not produce any of them in the proceeding.

         SECTION 6.04.  Waiver of Past Defaults.  Subject to Sections 6.02, 6.08
                        -----------------------
and  9.02,  the  Holders  of at least a  majority  in  principal  amount  of the
outstanding  Notes, by notice to the Trustee,  may waive an existing  Default or
Event of  Default  and its  consequences,  except a

                                     - 22 -


Default in the payment of  principal  of or interest on any Note as specified in
clause (a) or (b) of Section  6.01 or in respect of a covenant or  provision  of
this  Indenture  which cannot be modified or amended  without the consent of the
Holder of each  outstanding  Note affected.  Upon any such waiver,  such Default
shall cease to exist, and any Event of Default arising therefrom shall be deemed
to have been  cured,  for every  purpose of this  Indenture;  but no such waiver
shall extend to any  subsequent  or other  Default or Event of Default or impair
any right consequent thereto.

         SECTION 6.05.  Control by Majority.  The Holders of at least a majority
                        -------------------
in  aggregate  principal  amount of the  outstanding  Notes may direct the time,
method and place of conducting any  proceeding  for any remedy  available to the
Trustee or exercising any trust or power conferred on the Trustee; provided that
the Trustee may refuse to follow any direction if the Trustee,  being advised by
counsel, determines that the actions or proceedings so directed may not lawfully
be taken or if the Trustee in good faith by its board of  directors or executive
committee  or a trust  committee of  directors  or trustees  and/or  responsible
officers  shall  determine  that the actions or  proceedings  so directed  would
involve  the Trustee in  personal  liability;  and  provided  further,  that the
Trustee may take any other action it deems proper that is not inconsistent  with
any such direction received from Holders of Notes.

         SECTION  6.06.  Payment of Securities on Default;  Suit  Therefor.  The
                         -------------------------------------------------
Company  covenants  that (a) in case default shall be made in the payment of any
installment  of interest on any of the Notes,  as and when the same shall become
due and payable,  and such default shall have continued for a period of 30 days,
or (b) in case  default  shall be made in the payment of principal of any of the
Notes,  as and when the same shall have  become due and  payable,  whether  upon
maturity of the Notes or upon declaration or otherwise,  then upon demand of the
Trustee,  the Company will pay to the  Trustee,  for the benefit of the Holders,
the whole  amount  that then  shall have  become  due and  payable on all of the
Notes, for principal or interest, if any, as the case may be, with interest upon
the  overdue  principal  and (to the extent  that  payment of such  interest  is
enforceable  under  applicable law), upon overdue  installments of interest,  if
any, at the same rate as the rate of interest  specified  in the Notes;  and, in
addition thereto, such further amount as shall be sufficient to cover reasonable
compensation to the Trustee,  its agents,  attorneys and counsel,  and all other
reasonable  expenses and  liabilities  incurred,  and all advances  made, by the
Trustee except as a result of its negligence or bad faith.

         SECTION  6.07.  Limitation  on Suits.  A Holder may not  institute  any
                         --------------------
proceeding,  judicial or otherwise, with respect to this Indenture or the Notes,
or for the  appointment  of a  receiver  or  trustee,  or for any  other  remedy
hereunder, unless:

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

                  (ii) the Holders of at least 25% in aggregate principal amount
         of outstanding  Notes shall have made a written  request to the Trustee
         to pursue such remedy;

                  (iii)  such  Holder or  Holders  offer the  Trustee  indemnity
         satisfactory to the Trustee against any costs, liability or expense;

                                     - 23 -


                  (iv) the Trustee  does not comply  with the request  within 60
         days after receipt of the request and the offer of indemnity; and

                  (v) during  such 60-day  period,  the Holders of a majority in
         aggregate  principal  amount of the  outstanding  Notes do not give the
         Trustee a direction that is inconsistent with the request.

         For purposes of Section 6.05 of this  Indenture  and this Section 6.07,
the Trustee shall comply with TIA Section 316(a) in making any  determination of
whether the Holders of the required  aggregate  principal  amount of outstanding
Notes have  concurred  in any request or  direction of the Trustee to pursue any
remedy available to the Trustee or the Holders with respect to this Indenture or
the Notes or otherwise under the law.

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

         SECTION 6.08. Rights of Holders to Receive Payment. Notwithstanding any
                       ------------------------------------
other provision of this Indenture,  the right of any Holder of a Note to receive
payment of the  principal  of or  interest on such Note or to bring suit for the
enforcement  of any such  payment,  on or after  the due date  expressed  in the
Notes, shall not be impaired or affected without the consent of such Holder.

         SECTION  6.09.  Collection  Suit by Trustee.  If an Event of Default in
                         ---------------------------
payment of principal or interest  specified in clause (a) or (b) of Section 6.01
occurs and is continuing,  the Trustee may recover  judgment in its own name and
as trustee of an express  trust  against the Company or any other obligor of the
Notes for the whole amount of principal and accrued interest  remaining  unpaid,
together with interest on overdue principal, 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  6.10.  Trustee May File Proofs of Claim.  The Trustee may file
                         --------------------------------
such  proofs of claim  and other  papers or  documents  as may be  necessary  or
advisable  in order to have the claims of the Trustee  (including  any claim for
the  reasonable  compensation,  expenses,  disbursements  and  advances  of  the
Trustee,  its agents and counsel,  and any other  amounts due the Trustee  under
Section 7.07) and the Holders  allowed in any judicial  proceedings  relative to
the Company (or any other  obligor of the Notes),  its creditors or its property
and  shall be  entitled  and  empowered  to  collect  and  receive  any  monies,
securities or other property  payable or deliverable upon conversion or exchange
of the  Notes  or upon any such  claims  and to  distribute  the  same,  and any
custodian,  receiver,  assignee,  trustee,  liquidator,  sequestrator  or  other
similar  official in any such judicial  proceeding is hereby  authorized by each
Holder to make such  payments to the Trustee  and, in the event that the Trustee
shall consent to the making of such payments directly to the Holders,  to pay to
the  Trustee  any amount due 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.  Nothing herein  contained  shall be
deemed to empower the Trustee to  authorize or consent to, or accept or adopt on
behalf of any Holder,  any plan of  reorganization,  arrangement,  adjustment or
composition  affecting  the Notes

                                     - 24 -


or the rights of any Holder  thereof,  or to  authorize  the  Trustee to vote in

         principal  of and  interest on the Notes in respect of which or for the
         benefit of which such money has been collected,  with interest upon the
         overdue  installments  of interest,  to the extent lawful,  at the same

         such Notes for principal and interest, respectively; and

                  Third:  to the Company or any other obligors of the Notes,  as
         their interests may appear, or as a court of competent jurisdiction may

litigant in such suit to file an  undertaking  to pay the costs of the suit, and
the court may assess reasonable  costs,  including  reasonable  attorneys' fees,

faith of the claims or defenses  made by the party  litigant.  This Section 6.12
does not apply to a suit by the Trustee,  a suit by a Holder pursuant to Section
6.08,  or a suit  by  Holders  of  more  than  10% in  principal  amount  of the
outstanding Notes.

         SECTION 6.13. Restoration of Rights and Remedies. If the Trustee or any
                       ----------------------------------
Holder has  instituted  any proceeding to enforce any right or remedy under this
Indenture and such proceeding has been discontinued or abandoned for any reason,
or has been determined  adversely to the Trustee or to such Holder, then, and in
every such case,  subject to any determination in such proceeding,  the Company,
the Trustee and the Holders  shall be restored  severally  and  respectively  to
their former  positions  hereunder and thereafter all rights and remedies of the
Company, Trustee and the Holders shall continue as though no such proceeding had
been instituted.

                       ------------------------------
conferred  upon or  reserved  to the Trustee or to the Holders is intended to be
exclusive of any other right or remedy, and every right and remedy shall, to the
extent  permitted by law, be cumulative and in addition to every other right and

                                     - 25 -


otherwise, shall not prevent the concurrent assertion or employment of any other

Trustee or of any Holder to exercise any right or remedy accruing upon any Event
of Default  shall impair any such right or remedy or  constitute a waiver of any
such Event of Default or an acquiescence  therein.  Every right and remedy given

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

                       -------------------------
through (d):

                  (i) the Trustee may conclusively  rely, and shall be protected
         in acting or refraining from acting, upon any resolution,  certificate,
         statement,  instrument,  opinion,  report, notice, request,  direction,
         consent,  order, bond, debenture,  note, other evidence of indebtedness

                  (ii) before the Trustee acts or refrains  from acting,  it may
         require an Officers' Certificate or an Opinion of Counsel,  which shall
         conform  to  Section  11.04.  The  Trustee  shall not be liable for any
         action  it takes or omits  to take in good  faith in  reliance  on such

         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 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;

                                     - 26 -


                  (v) 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
         its rights or powers,  provided  that the  Trustee's  conduct  does not
         constitute negligence or bad faith;

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

                  (vii) the Trustee shall not be bound to make any investigation
         into the  facts  or  matters  stated  in any  resolution,  certificate,

         consent,  order, bond, debenture,  note, other evidence of indebtedness
         or other paper or document,  but the Trustee,  in its  discretion,  may
         make such further inquiry or  investigation  into such facts or matters
         as it may see fit,  and, if the Trustee  shall  determine  to make such
         further inquiry or  investigation,  it shall be entitled to examine the
         books,  records and premises of the Company  personally  or by agent or
         attorney;

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

                  (ix) the  Trustee  shall not be  deemed to have  notice of any
         Default or Event of Default unless a Responsible Officer of the Trustee
         has  actual  knowledge  thereof or unless  written  notice of any event
         which is in fact such a  Default  is  received  by the  Trustee  at the
         Corporate Trust Office of the Trustee,  and such notice  references the
         Notes and this Indenture;

                  (x)  the  rights,  privileges,   protections,  immunities  and
         benefits given to the Trustee, including, without limitation, its right
         to be  indemnified,  are extended to, and shall be enforceable  by, the

         and other Person employed to act hereunder; and

                  (xi) the  Trustee  may  request  that the  Company  deliver an
         Officers'  Certificate  setting forth the names of  individuals  and/or
         titles of Officers  authorized at such time to take  specified  actions
         pursuant to this Indenture,  which Officers'  Certificate may be signed
         by any Person  authorized to sign an Officers'  Certificate,  including
         any  Person   specified  as  so  authorized  in  any  such  certificate
         previously delivered and not superseded.

         SECTION  7.03.  Individual  Rights  of  Trustee.  The  Trustee,  in its
                         -------------------------------
individual or any other  capacity,  may become the owner or pledgee of Notes and
may otherwise  deal with the Company or its  Affiliates  with the same rights it
would  have if it were not the  Trustee.  Any  Agent  may do the same  with like
rights. However, the Trustee is subject to TIA Sections 310(b) and 311.

         SECTION  7.04.   Trustee's   Disclaimer.   The  Trustee  (i)  makes  no
                          ----------------------
representation  as to the  validity or adequacy of this  Indenture or the Notes,
(ii)  shall not be  accountable  for

                                     - 27 -


the Company's use or  application of the proceeds from the Notes and (iii) shall
not be responsible  for any statement in the Notes other than its certificate of
authentication.

         SECTION 7.05. Notice of Default. If any Default or any Event of Default
                       -----------------
occurs and is  continuing  and if such Default or Event of Default is known to a
Responsible Officer of the Trustee, the Trustee shall mail to each Holder in the
manner and to the extent provided in TIA Section 313(c) notice of the Default or
Event of Default within 45 days after it occurs, unless such Default or Event of
Default has been cured; provided, however, that, except in the case of a default
in the payment of the principal of or interest on any Note, the Trustee shall be
protected in  withholding  such notice if and so long as the board of directors,
the executive  committee or a trust  committee of directors  and/or  Responsible
Officers of the Trustee in good faith  determine  that the  withholding  of such
notice is in the interest of the Holders.

         SECTION 7.06. Reports by Trustee to Holders.  Within 60 days after each
                       -----------------------------
July 15,  beginning with July 15, 2002, the Trustee shall mail to each Holder as
provided in TIA Section 313(c) a brief report, if and as required by TIA Section
313(a), dated as of such July 15.

         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 Commission and each
stock exchange on which the Securities are listed in accordance with TIA Section
313(d).  The Company shall  promptly  notify the Trustee when the Securities are
listed on any stock exchange or of any delisting thereof.

         SECTION 7.07. Compensation and Indemnity.  The Company shall pay to the
                       --------------------------
Trustee  such  compensation  as shall be agreed upon in writing for its services
hereunder.  The  compensation  of the Trustee shall not be limited by any law on
compensation  of a trustee of an express trust.  The Company shall reimburse the
Trustee upon  request for all  reasonable  disbursements,  expenses and advances
incurred or made by the  Trustee  without  negligence  or bad faith on its part.
Such expenses  shall  include the  reasonable  compensation  and expenses of the
Trustee's agents and counsel.

         The Company  shall  indemnify the Trustee and any  predecessor  trustee
for,  and hold it harmless  against,  any and all loss or  liability  or expense
incurred by it without  negligence or bad faith on its part in  connection  with
the  acceptance or  administration  of this  Indenture and its duties under this
Indenture and the Notes,  including  the costs and expenses of defending  itself
against any claim or liability and of complying  with any process served upon it
or any of its officers in connection  with the exercise or performance of any of
its powers or duties  under this  Indenture  and the Notes.  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,  unless the Company is materially prejudiced thereby.
The  Company  shall  defend the claim and the  Trustee  shall  cooperate  in the
defense.  Unless  otherwise  set forth  herein,  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.

         To secure the Company's  payment  obligations in this Section 7.07, the
Trustee  shall have a lien prior to the Notes on all money or  property  held or
collected by the Trustee,  in its capacity

                                     - 28 -


as Trustee,  except  money or  property  held in trust to pay  principal  of and
interest on particular Notes.

         If the Trustee incurs expenses or renders services after the occurrence
of an Event of  Default  specified  in clause (d) or (e) of  Section  6.01,  the
expenses and the  compensation  for the services  will be intended to constitute
expenses of  administration  under Title 11 of the United States Bankruptcy Code
or any applicable federal or state law for the relief of debtors.

         The  provisions of this Section 7.07 shall survive the  termination  of
this Indenture and the resignation and removal of the Trustee.

         The Trustee shall comply with the  provisions of TIA Section  313(b)(2)
to the extent applicable.

         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
7.08.

         The  Trustee  may  resign at any time by so  notifying  the  Company in
writing  at least 30 days  prior to the date of the  proposed  resignation.  The
Holders of a majority in principal  amount of the  outstanding  Notes may at any
time remove the Trustee by so notifying  the Trustee and may appoint a successor
Trustee.  The  Company  may remove the  Trustee if: (i) the Trustee is no longer
eligible  under  Section  7.10;  (ii) the  Trustee is  adjudged a bankrupt or an
insolvent;  (iii) a receiver or other public officer takes charge of the Trustee
or its property; or (iv) 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 Holders
of a  majority  in  principal  amount of the  outstanding  Notes  may  appoint a
successor Trustee to replace the successor Trustee appointed by the Company.  If
the successor  Trustee does not deliver its written  acceptance  required by the
next succeeding paragraph of this Section 7.08 within 30 days after the retiring
Trustee resigns or is removed,  the retiring Trustee, the Company or the Holders
of a majority in principal  amount of the outstanding  Notes may, at the expense
of the Company, petition any court of competent jurisdiction for 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.  Immediately  after the
delivery of such  written  acceptance,  subject to the lien  provided in Section
7.07, (i) the retiring Trustee shall transfer all property held by it as Trustee
to the  successor  Trustee,  (ii) the  resignation  or removal  of the  retiring
Trustee shall become  effective  and (iii) the successor  Trustee shall have all
the rights,  powers and duties of the Trustee under this Indenture.  A successor
Trustee shall mail notice of its succession to each Holder. No successor Trustee
shall  accept  its  appointment  unless  at the  time  of such  acceptance  such
successor Trustee shall be qualified and eligible under this Article.

         If the Trustee is no longer  eligible  under Section 7.10 or shall fail
to comply with TIA Section 310(b),  any Holder who satisfies the requirements of
TIA Section  310(b) may  petition any court of  competent  jurisdiction  for the
removal of the Trustee and the  appointment  of a

                                     - 29 -


successor  Trustee.  If at any time the  Trustee  shall  cease to be eligible in
accordance  with the  provisions of this Section 7.08,  the Trustee shall resign
immediately in the manner and with the effect provided in this Section.

         The Company shall give notice of any resignation and any removal of the
Trustee and each appointment of a successor Trustee to all Holders.  Each notice
shall include the name of the successor Trustee and the address of its Corporate
Trust Office.

         Notwithstanding  replacement  of the Trustee  pursuant to this  Section
7.08, the Company's obligation under Section 7.07 shall continue for the benefit
of the retiring Trustee.

         SECTION  7.09.  Successor  Trustee  by  Merger,  Etc.  If  the  Trustee
                         ------------------------------------
consolidates  with,  merges or converts into, or transfers all or  substantially
all of its corporate trust business to, another  corporation or national banking
association,  the  resulting,  surviving or transferee  corporation  or national
banking  association without any further act shall be the successor Trustee with
the same  effect  as if the  successor  Trustee  had been  named as the  Trustee
herein,  provided  such  corporation  shall be otherwise  qualified and eligible
under this Article.

         SECTION 7.10.  Eligibility.  This Indenture shall always have a Trustee
                        -----------
who satisfies the requirements of TIA Section 310(a)(1).  The Trustee shall have
a combined capital and surplus of at least $100 million as set forth in its most
recent  published annual report of condition that is subject to the requirements
of applicable  Federal or state  supervising or examining  authority.  If at any
time the Trustee shall cease to be eligible in accordance with the provisions of
this Section,  the Trustee shall resign  immediately  in the manner and with the
effect specified in this Article.

         SECTION 7.11.  Money Held in Trust. The Trustee shall not be liable for
                        -------------------
interest  on any money  received  by it except as the Trustee may agree with the
Company.  Money held in trust by the Trustee need not be  segregated  from other
funds  except to the extent  required  by law and except for money held in trust
under Article Eight of this Indenture.

         than  destroyed,  lost or stolen Notes that have been replaced or Notes
         that are paid pursuant to Section 4.01 or Notes for whose payment money
         or securities have theretofore been held in trust and thereafter repaid
         to the Company, as provided in Section 8.05) have been delivered to the
         Trustee for  cancellation  and the Company has paid all sums payable by
         it hereunder; or

                  (ii) (A) the Notes  mature  within one year,  (B) the  Company
         irrevocably  deposits  in trust with the Trustee  during such  one-year
         period,  under the terms of an

         irrevocable  trust agreement in form and substance  satisfactory to the
         Trustee,  as trust funds solely for the benefit of the Holders for that
         purpose,  money  or  U.S.  Government  Obligations  sufficient  (in the
         opinion  of  a  nationally   recognized  firm  of  independent   public
         accountants  expressed in a written  certification thereof delivered to
         the Trustee), without consideration of any reinvestment of any interest
         thereon, to pay principal and interest on the Notes to maturity, and to
         pay all other sums payable by it hereunder,  (C) no Default or Event of
         Default with respect to the Notes shall have occurred and be continuing
         on the date of such  deposit,  (D) such  deposit  will not  result in a
         breach or violation of, or constitute a default  under,  this Indenture
         or any other agreement or instrument to which the Company is a party or
         by which it is bound and (E) the Company has  delivered  to the Trustee
         an  Officers'  Certificate  and an  Opinion  of  Counsel,  in each case
         stating that all conditions  precedent  provided for herein relating to
         the  satisfaction  and discharge of this  Indenture  have been complied
         with.

         With respect to the  foregoing  clause (i), the  Company's  obligations
under Section 7.07 shall survive. With respect to the foregoing clause (ii), the
Company's  obligations in Sections 2.02,  2.03,  2.04,  2.05,  2.06, 2.07, 2.08,
2.09,  4.01, 4.02, 7.07, 7.08, 8.04, 8.05 and 8.06 shall survive until the Notes
are no  longer  outstanding.  Thereafter,  only  the  Company's  obligations  in
Sections 7.07,  8.04,  8.05 and 8.06 shall survive.  After any such  irrevocable
deposit,  the Trustee upon request shall acknowledge in writing the discharge of
the Company's  obligations  under the Notes and this Indenture  except for those
surviving obligations specified above.

         SECTION 8.02.  Defeasance and Discharge of Indenture.  The Company will
                        -------------------------------------
be deemed to have paid and will be discharged  from any and all  obligations  in
respect of the Notes on the 91st day after the date of the  deposit  referred to
in clause (a) of this Section 8.02, and the provisions of this Indenture will no
longer be in effect with respect to the Notes,  and the Trustee,  at the expense
of the Company, shall execute proper instruments acknowledging the same if:

         (a) with  reference to this Section 8.02,  the Company has  irrevocably
deposited  or caused to be  irrevocably  deposited  with the Trustee (or another
trustee  satisfying  the  requirements  of Section 7.10) and conveyed all right,
title and  interest to the Trustee  for the  benefit of the  Holders,  under the
terms of an irrevocable  trust  agreement in form and substance  satisfactory to
the Trustee as trust funds in trust, specifically pledged to the Trustee for the
benefit of the Holders as security for payment of the principal of and interest,
if any, on the Notes,  and dedicated  solely to, the benefit of the Holders,  in
and to (1) money in an amount, (2) U.S. Government Obligations that, through the
payment of interest and principal in respect  thereof in  accordance  with their
terms,  will provide,  not later than one day before the due date of any payment
referred to in this clause (a), money in an amount or (3) a combination  thereof
in an amount  sufficient,  in the  opinion of a  nationally  recognized  firm of
independent  public  accountants  expressed in a written  certification  thereof
delivered to the Trustee,  to pay and discharge,  without  consideration  of the
reinvestment of such interest and after payment of all federal,  state and local
taxes or other  charges  and  assessments  in  respect  thereof  payable  by the
Trustee,  the principal of and interest on the  outstanding  Notes on the Stated
Maturity of such  principal or interest;  provided  that the Trustee  shall have
been  irrevocably  instructed  to apply such money or the  proceeds of such U.S.
Government  Obligations  to the  payment of such  principal  and  interest  with
respect to the Notes;

                                     - 31 -


         (b) the Company has  delivered to the Trustee  either (x) an Opinion of
Counsel to the effect that Holders will not recognize  income,  gain or loss for
federal income tax purposes as a result of the Company's  exercise of its option
under this  Section  8.02 and will be subject to federal  income tax on the same
amount and in the same  manner and at the same times as would have been the case
if such option had not been  exercised,  which Opinion of Counsel shall be based
upon (and  accompanied by a copy of) a ruling of the Internal Revenue Service to
the same effect unless there has been a change in applicable  federal income tax
law after the  Closing  Date such that a ruling is no longer  required  or (y) a
ruling directed to the Trustee received from the Internal Revenue Service to the
same effect as the aforementioned Opinion of Counsel.

         (c)  immediately  after giving effect to such  deposit,  on a pro forma
basis,  no Default or Event of Default  shall have occurred and be continuing on
the date of such  deposit  or,  insofar as  Sections  6.01(d)  and  6.01(e)  are
concerned,  at any time during the period ending on the 91st day after such date
of such deposit;

         (d) if the Notes are then listed on a national securities exchange, the
Company  has  delivered  to the Trustee an Opinion of Counsel to the effect that
the Notes  will not be  delisted  as a result of such  deposit,  defeasance  and
discharge; and

         (e) the Company has  delivered to the Trustee an Officers'  Certificate
and an Opinion of Counsel,  in each case stating that all  conditions  precedent
provided for herein relating to the defeasance contemplated by this Section 8.02
have been complied with.

         Notwithstanding  the  foregoing,  prior to the end of the 91-day period
referred  to in  clause  (c)  of  this  Section  8.02,  none  of  the  Company's
obligations  under this Indenture shall be discharged.  Subsequent to the end of

the rights, powers, trusts, duties and immunities of the Trustee hereunder shall
survive  until  the  Notes  are no  longer  outstanding.  Thereafter,  only  the
Company's obligations in Sections 7.07, 8.04, 8.05 and 8.06 shall survive.

         After any such  irrevocable  deposit,  the Trustee upon  request  shall
acknowledge  in writing the  discharge of the  Company's  obligations  under the
Notes  and  this  Indenture  except  for  those  surviving  obligations  in  the
immediately preceding paragraph.

and 5.01 and clause (c) of Section 6.01 with respect to Sections 4.03,  4.05 and
5.01,  and  clause  (c) of  Section  6.01  shall be deemed not to be an Event of

         benefit  of the  Holders,  under  the  terms  of an  irrevocable  trust
         agreement in form and  substance  satisfactory  to the Trustee as trust
         funds in trust,  specifically pledged to the Trustee for the benefit of
         the Holders as security for payment of the  principal of and  interest,
         if any,  on the Notes,  and  dedicated  solely  to, the  benefit of

                                     - 32 -


         the  Holders,  in and to (A) money in an  amount,  (B) U.S.  Government
         Obligations  that,  through the payment of interest  and  principal  in
         respect thereof in accordance with their terms, will provide, not later
         than one day before  the due date of any  payment  referred  to in this
         clause  (i),  money in an amount  or (C) a  combination  thereof  in an
         amount  sufficient,  in the opinion of a nationally  recognized firm of
         independent  public  accountants  expressed in a written  certification
         thereof  delivered  to the  Trustee,  to  pay  and  discharge,  without
         consideration of the reinvestment of such interest and after payment of
         all federal,  state and local taxes or other charges and assessments in
         respect thereof  payable by the Trustee,  the principal of and interest
         on the  outstanding  Notes on the Stated  Maturity of such principal or
         interest;  provided  that  the  Trustee  shall  have  been  irrevocably
         instructed to apply such money or the proceeds of such U.S.  Government
         Obligations  to the payment of such principal and interest with respect
         to the Notes;

                  (ii) the  Company has  delivered  to the Trustee an Opinion of
         Counsel to the effect that the Holders will not recognize income,  gain
         or loss for federal income tax purposes as a result of such deposit and
         defeasance  of certain  covenants  and  Events of  Default  and will be
         subject to federal income tax on the same amount and in the same manner
         and at the same times as would have been the case if such  deposit  and
         defeasance had not occurred;

                  (iii) immediately after giving effect to such deposit on a pro
         forma basis,  no Default or Event of Default shall have occurred and be
         continuing on the date of such deposit or, insofar as Sections  6.01(d)
         and 6.01(e) are concerned,  at any time during the period ending on the
         91st day after such date of such deposit;

                  (iv) if the Notes are then  listed  on a  national  securities
         exchange,  the  Company  has  delivered  to the  Trustee  an Opinion of
         Counsel to the effect  that the Notes will not be  delisted as a result
         of such deposit, defeasance and discharge; and

                  (v) the Company  has  delivered  to the  Trustee an  Officers'
         Certificate  and an Opinion of Counsel,  in each case  stating that all
         conditions  precedent  provided for herein  relating to the  defeasance
         contemplated by this Section 8.03 have been complied with.

         SECTION 8.04.  Application of Trust Money. Subject to Section 8.06, the
                        --------------------------
Trustee or Paying Agent shall hold in trust money or U.S. Government Obligations
deposited  with it pursuant to Section  8.01,  8.02 or 8.03, as the case may be,
and  shall  apply  the  deposited  money  and the  money  from  U.S.  Government
Obligations  in accordance  with the Notes and this  Indenture to the payment of
principal  of and interest on the Notes;  but such money need not be  segregated
from other funds except to the extent required by law.

         SECTION 8.05.  Repayment to Company.  Subject to Sections  7.07,  8.01,
                        --------------------
8.02 and 8.03,  the  Trustee  and the Paying  Agent  shall  promptly  pay to the
Company upon request set forth in an Officers' Certificate any excess money held
by them at any time and  thereupon  shall be relieved  from all  liability  with
respect to such money. The Trustee and the Paying Agent shall pay to the Company
upon  request  any money held by them for the payment of  principal  or interest
that remains unclaimed for two years;  provided that the Trustee or Paying Agent
before  being  required  to make any payment  may cause to be  published  at the
expense of the Company once in

                                     - 33 -


a  newspaper  of  general  circulation  in The  City of New York or mail to each
Holder  entitled  to such money at such  Holder's  address  (as set forth in the
Security  Register)  notice that such money  remains  unclaimed and that after a
date  specified  therein  (which shall be at least 30 days from the date of such
publication or mailing) any unclaimed  balance of such money then remaining will
be repaid to the Company. After payment to the Company, Holders entitled to such
money  must look to the  Company  for  payment as  general  creditors  unless an
applicable law designates  another Person,  and all liability of the Trustee and
such Paying Agent with respect to such money shall cease.

         SECTION 8.06.  Reinstatement.  If the Trustee or Paying Agent is unable
                        -------------
to apply any money or U.S.  Government  Obligations  in accordance  with Section
8.01, 8.02 or 8.03, as the case may be, by reason of any legal  proceeding or by
reason  of  any  order  or  judgment  of any  court  or  governmental  authority
enjoining,  restraining or otherwise prohibiting such application, the Company's
obligations  under this  Indenture and the Notes shall be revived and reinstated
as though no deposit had occurred pursuant to Section 8.01, 8.02 or 8.03, as the
case may be,  until such time as the  Trustee or Paying  Agent is  permitted  to
apply all such money or U.S.  Government  Obligations in accordance with Section
8.01,  8.02 or 8.03, as the case may be;  provided that, if the Company has made
any  payment  of  principal  of  or  interest  on  any  Notes   because  of  the
reinstatement of its obligations,  the Company shall be subrogated to the rights
of the  Holders  of such Notes to receive  such  payment  from the money or U.S.
Government Obligations held by the Trustee or Paying Agent.

                       AMENDMENTS, SUPPLEMENTS AND WAIVERS

         SECTION 9.01. Without Consent of Holders. The Company,  when authorized
                       --------------------------
by a resolution of its Board of Directors  (as  evidenced by a Board  Resolution
delivered  to the  Trustee),  and the  Trustee  may  amend  or  supplement  this
Indenture or the Notes without notice to or the consent of any Holder:

                  (i) to cure any  ambiguity,  defect or  inconsistency  in this
         Indenture;

                  (ii) to comply with Article Five;

                  (iii) to comply with any  requirements  of the  Commission  in
         connection with any qualification of this Indenture under the TIA;

                  (iv) to evidence and provide for the acceptance of appointment

         of the Holders, to add any additional Events of Default with respect to
         the  Notes,  or to  surrender  any  right or power  conferred  upon the
         Company; or

                                     - 34 -


(vii)    to make any  change  that,  in the good  faith  opinion of the Board of
         Directors as evidenced by a Board  Resolution,  does not materially and
         adversely affect the rights of any Holder.

         SECTION  9.02.  With Consent of Holders.  Subject to Sections  6.04 and
                         -----------------------
6.08 and without prior notice to the Holders,  the Company,  when  authorized by
its Board of  Directors  (as  evidenced by a Board  Resolution  delivered to the
Trustee),  and the  Trustee  may amend  this  Indenture  and the Notes  with the
written  consent of the Holders of a majority in aggregate  principal  amount of
the Notes then outstanding, and the Holders of a majority in aggregate principal
amount of the Notes then  outstanding by written notice to the Trustee may waive
future  compliance  by the Company with any  provision of this  Indenture or the
Notes.

         Notwithstanding  the  provisions  of this  Section  9.02,  without  the
consent of each Holder  affected,  an  amendment  or waiver,  including a waiver
pursuant to Section 6.04, may not:

                  (i) change the Stated  Maturity  of the  principal  of, or any
         installment of interest on, any Note;

                  (ii)  reduce the  principal  amount of or interest on any Note
         except as provided in this Indenture;

                  (iii)  change any place or currency of payment of principal of
         or interest on any Note;

                  (iv) impair the right to institute suit for the enforcement of
         any payment on or after the Stated Maturity on any Note;

                  (v) reduce the  percentage or principal  amount of outstanding
         Notes the consent of whose Holders is necessary to modify or amend this
         Indenture or to waive compliance with certain  provisions of or certain
         Defaults under this Indenture;

                  (vi)  waive  a  default  in the  payment  of  principal  of or
         interest on any Note; or

                  (vii)  modify  any of the  provisions  of this  Section  9.02,
         except to increase any such percentage or to provide that certain other
         provisions of this  Indenture  cannot be modified or waived without the
         consent of the Holder of each outstanding Note affected thereby.

         It shall not be  necessary  for the consent of the  Holders  under this
Section  9.02  to  approve  the  particular  form  of  any  proposed  amendment,
supplement 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  affected  thereby a
notice briefly describing the amendment,  supplement or waiver. The Company will
mail supplemental indentures to Holders upon request. 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 supplemental indenture or waiver.


                                     - 35 -


         SECTION  9.03.  Action  by  Holders;  Record  Dates.  Whenever  in this
                         -------------------
Indenture  it is provided  that the Holders of a specified  aggregate  principal
amount of the outstanding Notes may take any action (including the making of any
demand or request, the giving of any notice,  consent or waiver or the taking of
any  other  action),  the fact that at the time of taking  any such  action  the
Holders of such specified amount have joined therein may be evidenced (a) by any
instrument  or any number of  instruments  of  similar  tenor  executed  by such
Holders in person or by agent or proxy  appointed in writing,  or (b) the record
of the Holders voting in favor thereof at any meeting of the Holders duly called
and  held  in  accordance  with  the  provisions  of  Article  Ten,  or (c)  any
combination  of such  instrument  or  instruments  and any such record of such a
meeting of the Holders.

         Subject to the  provisions  of  Sections  7.02 and 10.05,  proof of the
execution  of any  instrument  by a  Holder  or its  agent  or  proxy  shall  be
sufficient  if the  ownership  of the Notes shall be proved by (a) the  Security
Register or by a certificate  of the Registrar;  or (b) in accordance  with such
reasonable  rules and  regulations as may be prescribed by the Trustee or in any
other manner which the Trustee may deem sufficient.

         The Company may,  but shall not be obligated  to, fix a record date for
the purpose of  determining  the Holders  entitled to consent to any  amendment,
supplement or waiver. If a record date is fixed, then,  notwithstanding the last
two sentences of the  immediately  preceding  paragraph,  those persons who were
Holders at such record date (or their duly  designated  proxies)  and only those
persons shall be entitled to consent to such amendment,  supplement or waiver or
to revoke any consent previously given,  whether or not such persons continue to
be Holders  after such record date.  No such consent shall be valid or effective
for more than 90 days after such record date.

         After an amendment,  supplement or waiver becomes  effective,  it shall
bind every Holder unless it is of the type described in the second  paragraph of
Section  9.02.  In case of an amendment  or waiver of the type  described in the
second paragraph of Section 9.02, the amendment or waiver shall bind each Holder
who has consented to it and every subsequent Holder of a Note that evidences the
same indebtedness as the Note of the consenting Holder.

         SECTION 9.04.  Revocation and Effect of Consent.  Until an amendment or
                        --------------------------------
waiver becomes effective, a consent to it by a Holder is a continuing consent by
the  Holder  and every  subsequent  Holder of a Note or  portion  of a Note that
evidences the same debt as the Note of the consenting  Holder,  even if notation
of the consent is not made on any Note.  However,  any such Holder or subsequent
Holder  may revoke  the  consent  as to its Note or  portion  of its Note.  Such
revocation  shall be  effective  only if the  Trustee  receives  the  notice  of
revocation  before  the  date  the  amendment,   supplement  or  waiver  becomes
effective. An amendment,  supplement or waiver shall become effective on receipt
by the Trustee of written consents from the Holders of the requisite  percentage
in principal amount of the outstanding Notes.

         SECTION  9.05.  Notation  on or  Exchange  of Notes.  If an  amendment,
                         -----------------------------------
supplement  or waiver  changes the terms of a Note,  the Trustee may require the
Holder to  deliver  such Note to the  Trustee.  At the  Company's  expense,  the
Trustee may place an  appropriate  notation on the Note about the changed  terms
and return it to the Holder,  and the Trustee may place an appropriate  notation
on any Note  thereafter  authenticated.  Alternatively,  if the  Company  or the

                                     - 36 -


Trustee so determines,  the Company in exchange for the Note shall issue and the
Trustee shall  authenticate a new Note that reflects the changed terms.  Failure
to make the  appropriate  notation,  or issue a new Note,  shall not  affect the
validity and effect of such amendment, supplement or waiver.

         SECTION  9.06.  Trustee to Sign  Amendments,  Etc. The Trustee shall be
                         ---------------------------
entitled to receive, and shall be fully protected in relying upon, an Opinion of
Counsel  stating  that the  execution  of any  amendment,  supplement  or waiver
authorized  pursuant to this  Article  Nine is  authorized  or permitted by this
Indenture and that it will be valid and binding upon the Company. Subject to the
preceding sentence, the Trustee shall sign such amendment,  supplement or waiver
if the same  does not  adversely  affect  the  rights,  duties,  liabilities  or
immunities  of the Trustee.  The Trustee  may,  but shall not be  obligated  to,
execute any such amendment,  supplement or waiver that affects the Trustee's own
rights, duties or immunities under this Indenture or otherwise.

         SECTION 9.07.  Conformity with Trust Indenture Act. Every  supplemental
                        -----------------------------------
indenture   executed  pursuant  to  this  Article  Nine  shall  conform  to  the
requirements of the TIA as then in effect

         under applicable law.

as provided in Section 10.02.

                  Attention:  Corporate Trust Administration

         The  Company  or the  Trustee  by notice  to the  other  may  designate
additional or different addresses for subsequent notices or communications.

         Any notice or communication mailed to a Holder shall be mailed to it at
its address as it appears on the Security Register by first-class mail and shall
be sufficiently given to him if so mailed within the time prescribed. Any notice
or communication  shall also be so mailed to any Person described in TIA Section
313(c),  to the extent required by the TIA. Copies of any such  communication or
notice to a Holder  shall  also be mailed to the  Trustee  and each Agent at the
same time.

         Failure  to mail a notice  or  communication  to a Holder  as  provided
herein or any defect in any such  notice or  communication  shall not affect its
sufficiency  with respect to other Holders.  Except for a notice to the Trustee,
which is deemed given only when  received,  and except as otherwise  provided in
this Indenture, if a notice or communication is mailed in the manner provided in
this Section 11.02, it is duly given, whether or not the addressee receives it.

         Where this Indenture provides for notice in any manner, such notice may
be waived in writing by the Person  entitled  to  receive  such  notice,  either
before or after the  event,  and such  waiver  shall be the  equivalent  of such
notice.  Waivers of notice by Holders shall be filed with the Trustee,  but such
filing shall not be a condition precedent to the validity of any action taken in
reliance upon such waiver.

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

         Holders  may  communicate  pursuant  to TIA  Section  312(b) with other
Holders  with respect to their  rights  under this  Indenture or the Notes.  The
Company, the Trustee, the Registrar and anyone else shall have the protection of

2001 to, and  excluding,  the first  Interest  Payment  Date and then from,  and
including, the immediately preceding Interest Payment Date to which interest has
been paid or duly provided for to, but excluding, the next Interest Payment Date
or the Maturity Date, as the case may be; provided that, if there is no existing
default in the  payment of  interest  and this Note is  authenticated  between a
Record  Date  referred to on the face  hereof and the next  succeeding  Interest
Payment Date,  interest shall accrue from such Interest  Payment Date.  Interest
will be computed on the basis of a 360-day year of twelve 30-day months.

2.       Interest Rate Adjustment.
         ------------------------

         In the event that either Moody's or S&P downgrades the rating  ascribed
to the Company's  senior unsecured debt below A3 in the case of Moody's or below
A- in the case of S&P, the interest  rate payable on the Notes will be increased
by 0.25% for each Rating Category downgrade below the applicable level by either
rating agency. If following such an event, Moody's or S&P subsequently increases
the rating  ascribed to the Company's  senior  unsecured d

                                      A-5


ebt,  then the interest rate payable on the Notes will be decreased by 0.25% for
each Rating Category upgrade by either rating agency; provided, however, that in
no event will interest rate payable on the Notes be reduced to below the initial
interest rate as a result of this provision.  Any such interest rate increase or
decrease  will take effect from the  Interest  Payment Date next  following  the
related rating downgrade or upgrade, as the case may be.

3.       Method of Payment.
         -----------------

         The Company will pay interest on the  principal  amount of the Notes as
provided above on each January 15 and July 15,  commencing  July 15, 2002 to the
persons who are Holders (as  reflected in the Security  Register at the close of
business  on  the  fifteenth  calendar  day,  whether  or  not a  Business  Day,
immediately preceding the Interest Payment Date), in each case, even if the Note
is cancelled on  registration of transfer or registration of exchange after such
Record  Date;  provided  that,  with  respect to the payment of  principal,  the
Company  will make payment to the Holder that  surrenders  this Note to a Paying
Agent on or after January 15, 2007.

         The Company  will pay  principal  and, as provided  above,  interest in
money of the  United  States  that at the time of  payment  is legal  tender for
payment of public and private debts.  However, the Company may pay principal and
interest by its check payable in such money.  It may mail an interest check to a
Holder's  registered  address (as  reflected in the Security  Register).  If any
Interest Payment Date or the Maturity Date falls on a day that is not a Business
Day, the payment of principal and interest  will be made on the next  succeeding
Business Day as if made on the date such  payment was due, and no interest  will
accrue on such  payment for the period from and after the  Maturity  Date to the
date of such payment on the next succeeding Business Day.

4.       Paying Agent, Calculation Agent and Registrar.
         ---------------------------------------------

         Initially,  the Trustee will act as authenticating agent, Paying Agent,
Calculation  Agent and  Registrar.  The  Company  may change any  authenticating
agent, Paying Agent, Calculation Agent or Registrar without notice. The Company,
any  Subsidiary  or any  Affiliate  of any of  them  may  act as  Paying  Agent,
Registrar or Co-Registrar.

5.       Indenture; Limitations.
         ----------------------

         The Company  issued the Notes under an Indenture,  dated as of December
13, 2001 (the  "Indenture"),  between  the Company and The Bank of New York,  as
trustee  (the  "Trustee").  Capitalized  terms herein are used as defined in the
Indenture  unless  otherwise  indicated.  The terms of the Notes  include  those
stated in the Indenture and those made part of the Indenture by reference to the
Trust  Indenture  Act. The Notes are subject to all such terms,  and Holders are
referred to the  Indenture  and the Trust  Indenture  Act for a statement of all
such  terms.  To the extent  permitted  by  applicable  law, in the event of any
inconsistency between the terms of this Note and the terms of the Indenture, the
terms of the Indenture shall control.

         The Notes are general unsecured obligations of the Company.

         The  Company  may,  subject  to  Article  Four  of  the  Indenture  and
applicable law, issue additional Notes under the Indenture.

                                      A-6


6.       Redemption.
         ----------

         The Notes are not redeemable prior to the Maturity Date.

7.       Denominations; Transfer; Exchange.
         ---------------------------------

         The Notes are in registered  form without coupons in  denominations  of
$1,000 of principal  amount and multiples of $1,000 in excess thereof.  A Holder
may register the transfer or exchange of Notes in accordance with the Indenture.
The Registrar may require a Holder,  among other things, to furnish  appropriate
endorsements  and transfer  documents  and to pay any taxes and fees required by
law or permitted by the Indenture.

8.       Persons Deemed Owners.
         ---------------------

         A Holder shall be treated as the owner of a Note for all purposes.

9.       Unclaimed Money.
         ---------------

         If money for the payment of principal or interest remains unclaimed for
two  years,  the  Trustee  and the  Paying  Agent will pay the money back to the
Company at its request.  After that,  Holders entitled to the money must look to
the Company for payment,  unless an abandoned  property law  designates  another
Person,  and all  liability of the Trustee and such Paying Agent with respect to
such money  shall  cease.  In no event will  interest  accrue on such  unclaimed
monies.

10.      Discharge Prior to Maturity.
         ---------------------------

         If the  Company  deposits  with the  Trustee  money or U.S.  Government
Obligations  sufficient to pay the then outstanding principal of and accrued and
unpaid  interest on the Notes (a) to maturity,  the Company  will be  discharged
from the Indenture and the Notes,  except in certain  circumstances  for certain
provisions  thereof,  and  (b) to the  Stated  Maturity,  the  Company  will  be
discharged from certain covenants set forth in the Indenture.

11.      Amendment; Supplement; Waiver.
         -----------------------------

         Subject to certain  exceptions,  (a) the  Indenture or the Notes may be
amended or  supplemented  with the consent of the Holders of at least a majority
in principal  amount of the Notes then  outstanding and (b) any existing default
or  compliance  with any provision may be waived with the consent of the Holders
of at least a  majority  in  principal  amount  of the Notes  then  outstanding.
Without notice to or the consent of any Holder, the parties thereto may amend or
supplement  the  Indenture  or the  Notes  to,  among  other  things,  cure  any
ambiguity,  defect or inconsistency and make any change that does not materially
and adversely affect the rights of any Holder.

12.      Restrictive Covenants.
         ---------------------

         The  Indenture  imposes  certain  limitations  on  the  ability  of the
Company,  among other  things,  to (a) create  security  interests in the common
stock of any Significant Subsidiary to

                                      A-7


secure debt or (b) merge,  consolidate or transfer or lease substantially all of
its assets.  On or before a date not more than four months after the end of each
fiscal year,  the Company shall deliver to the Trustee an Officers'  Certificate
stating  whether  or not the  signers  thereof  know of any  Default or Event of
Default under such restrictive covenants.

13.      Successor Persons.
         -----------------

         When a successor  Person or other entity assumes all the obligations of
its predecessor under the Notes and the Indenture,  the predecessor  person will
be released from those obligations.

14.      Defaults and Remedies.
         ---------------------

         Any of the following events constitutes an "Event of Default" under the
Indenture:

         (a) default in the payment of the  principal of any of the Notes as and
when the same shall become due and payable either at maturity, by declaration or
otherwise; or

         (b) default in the payment of any installment of interest on any of the
Notes as and when the same shall become due and payable, and continuance of such
default for a period of 30 days; or

         (c) failure on the part of the  Company  duly to observe or perform any
other  of the  covenants  or  agreements  on the  part  of the  Company  in this
Indenture  applicable  to the Notes  for a period  of 90 days  after the date on
which written notice of such failure,  specifying such failure and requiring the
Company to remedy the same and stating that such notice is a "Notice of Default"
hereunder,  shall  have been  given to the  Company  by the  Trustee,  or to the
Company and the Trustee by the  Holders of at least 25% in  aggregate  principal
amount of the Notes at the time outstanding; or

         (d) a court having jurisdiction in the premises shall enter a decree or
order for  relief in respect of the  Company  in an  involuntary  case under any
applicable  bankruptcy,  insolvency  or other  similar law now or  hereafter  in
effect,  or appointing a receiver,  liquidator,  assignee,  custodian,  trustee,
sequestrator (or similar official) of the Company or for any substantial part of
its property,  or ordering the winding-up or liquidation of its affairs and such
decree or order shall remain unstayed and in effect for a period of 90 days; or

         (e) the Company shall  commence a voluntary  case under any  applicable
bankruptcy, insolvency or other similar law now or hereafter in effect, or shall
consent  to the entry of any order for relief in an  involuntary  case under any
such law,  or shall  consent to the  appointment  of or taking  possession  by a
receiver,  liquidator,  assignee, trustee,  custodian,  sequestrator (or similar
official) of the Company or for any substantial  part of its property,  or shall
make any general assignment for the benefit of creditors.

         If an Event of  Default,  as  defined in the  Indenture,  occurs and is
continuing, the Trustee may, and at the direction of the Holders of at least 25%
in aggregate  principal amount of the Notes then outstanding shall,  declare all
the Notes to be due and payable.  If a  bankruptcy  or  insolvency  default with
respect to the Company occurs and is continuing,  the Notes

                                      A-8


automatically  become due and payable.  Holders may not enforce the Indenture or
the Notes except as provided in the Indenture. The Trustee may require indemnity
satisfactory  to it before it enforces the  Indenture  or the Notes.  Subject to
certain  limitations,  Holders of at least a majority in principal amount of the
Notes then  outstanding  may direct the Trustee in its  exercise of any trust or
power.

15.      Trustee Dealings with the Company.
         ---------------------------------

         The  Trustee  under  the  Indenture,  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.

16.      No Recourse Against Others.
         --------------------------

         No  incorporator or any past,  present or future partner,  stockholder,
other equityholder,  officer, director, employee or controlling person, as such,
of the  Company or of any  successor  Person  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 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.

17.      Authentication.
         --------------

         This Note shall not be valid until the Trustee or authenticating  agent
signs the certificate of authentication on the other side of this Note.

18.      Abbreviations.
         -------------

Dear Sirs:

         This  letter  relates  to U.S.  $__________  principal  amount of Notes
represented  by a Note (the  "Legended  Note")  which  bears a legend  outlining
restrictions  upon transfer of such Legended  Note.  Pursuant to Section 2.02 of

of) a person outside the United States to whom the Notes could be transferred in
accordance with Rule 904 of Regulation S promulgated  under the U.S.  Securities

certificate for an unlegended  certificate  representing an identical  principal

         You and the  Company  are  entitled  to rely upon this  letter  and are

                       6.20% Notes due 2007 (the "Notes")
                       ----------------------------------

Dear Sirs:

         In  connection  with our  proposed  purchase of  $__________  aggregate
principal amount of the Notes, we confirm that:

         1. We understand  that any subsequent  transfer of the Notes is subject
to certain  restrictions  and conditions set forth in the Indenture  dated as of
December 13, 2001 (the  "Indenture")  relating to the Notes and the  undersigned
agrees to be bound by, and not to resell, pledge or otherwise transfer the Notes
except in compliance  with such  restrictions  and conditions and the Securities
Act of 1933, amended (the "Securities Act").

         2. We  understand  that the offer  and sale of the Notes  have not been
registered  under the  Securities  Act,  and that the Notes may not be  offered,
sold,  pledged or otherwise  transferred  except as  permitted in the  following
sentence. We agree, on our own behalf and on behalf of any accounts for which we
are acting as  hereinafter  stated,  that if we should sell any Notes within the
time period referred to in Rule 144(k) of the Securities Act as in effect on the
date of  transfer  of the  Notes,  we will do so only (A) to the  Company or any
subsidiary thereof, (B) in accordance with Rule 144A under the Securities Act to
a "qualified  institutional  buyer" (as defined therein),  (C) inside the United
States to an institutional  "accredited investor" (as defined below) that, prior
to  such  transfer,  furnishes  (or  has  furnished  on  its  behalf  by a  U.S.
broker-dealer)  to you and to the Company a signed letter  substantially  in the
form of this  letter  and,  if  such  transfer  is in  respect  of an  aggregate
principal amount of less than $250,000,  an opinion of counsel acceptable to the
Company that such transfer is in compliance with the Securities Act, (D) outside
the  United  States  in  accordance  with  Rule 904 of  Regulation  S under  the
Securities Act, (E) pursuant to the exemption from registration provided by Rule
144 under the  Securities  Act (if  available)  or (F)  pursuant to an effective
registration statement under the Securities Act, and we further agree to provide
to any  person  purchasing  any of the  Notes  from us a  notice  advising  such
purchaser that resales of the Notes are restricted as stated herein.

         3. We understand  that, on any proposed resale of any Notes, we will be
required to furnish to you and the Company such  certifications,  legal opinions
and other  information as you
