         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 for so long as such failure shall continue.  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  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; provided, however,
that neither the Company, a Subsidiary of the Company nor an Affiliate of any of
them shall act as Paying Agent in connection with the defeasance of the Notes or
the discharge of this Indenture under Article Eight.

         The Company initially appoints the Trustee as Registrar,  Paying Agent,
authenticating  agent and agent for  service of notice and  demands.  If, at any
time,  the Trustee is not the Registrar,  the Registrar  shall make available to
the Trustee on or before each  Interest  Payment Date and at such other times as
the Trustee may  reasonably  request,  the names and addresses of the Holders as
they appear in the Note Register.

         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 the principal,  premium,  if any, or
interest on any Notes,  the Company shall deposit with the Paying Agent money in
immediately  available funds sufficient to pay such principal,  premium, if any,
or interest so becoming due. The Company  shall  require each Paying  Agent,  if
any,  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,  premium,  if any, or interest
on the Notes (whether such money has been paid to it by the Company or any other
obligor on the Notes),  and that 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, premium, if any, 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,  premium, if any, 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 as required by this Section 2.05.


<PAGE>

         SECTION  2.06.  Transfer and  Exchange.  The Notes are issuable only in
registered  form.  A Holder may  transfer a Note 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  registration
of the transfer by the Registrar in the Note Register. Prior to the registration
of any transfer by a Holder as provided herein,  the Company,  the Trustee,  and
any agent of the Company or the Trustee 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 neither the Company, the Trustee, nor 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 Depository (or its agent),  and that ownership of a beneficial
interest  in the 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;  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  in  accordance  with  the  terms,
conditions and  restrictions  hereof,  the Company shall execute and the Trustee
shall authenticate Notes at the Registrar's  request. No service charge shall be
made to any Holder for any registration of transfer or exchange or redemption 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 transfers,  exchanges or redemptions  pursuant to Section 2.11, 3.08, 4.11,
4.12 or 9.04).

         The Registrar shall not be required (i) to issue, register the transfer
of or exchange any Note during a period  beginning at the opening of business 15
days before the day of the mailing of a notice of redemption  of Notes  selected
for  redemption  under  Section  3.03 or Section 3.08 and ending at the close of
business  on the day of such  mailing,  or (ii) to register  the  transfer of or
exchange any Note so selected  for  redemption  in whole or in part,  except the
unredeemed portion of any Note being redeemed in part.

         SECTION  2.07.   Book-Entry  Provisions  for  Global  Notes.  (a)  Each
Restricted  Global and Regulation S Global  initially shall (i) be registered in
the  name  of the  Depository  for  such  Global  Note  or the  nominee  of such
Depository,  (ii) be delivered to the Trustee as custodian  for such  Depository
and (iii) bear legends as set forth in Section 2.02 hereof.

         Members of, or Participants in, the Depository  ("Agent Members") shall
have no rights  under this  Indenture  with  respect to any Global  Note held on
their behalf by the  Depository,  or the Trustee as its custodian,  or under any
Global Note, and the  Depository 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

<PAGE>

authorization  furnished by the Depository or impair,  as between the Depository
and its Agent  Members,  the  operation of  customary  practices  governing  the
exercise of the rights of a beneficial owner 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  Depository,  its  successors or
their respective nominees.  Transfers of interests in one Global Note to parties
who will hold the interests through the same Global Note will be effected in the
ordinary way in accordance with the respective rules and operating procedures of
the DTC,  Euroclear  or  Cedelbank,  as the case may be, and the  provisions  of
Section  2.08 hereof.  In  addition,  U.S.  Certificated  Notes or  Regulation S
Certificated Notes shall be transferred to all beneficial owners in exchange for
their  beneficial  interests  in a  Restricted  Global or a Regulation S Global,
respectively,  if (i) the Depository  with respect to such Global Notes notifies
the Company  that it is unwilling  or unable to continue as  Depository  for the
Restricted  Global  or the  Regulation  S  Global,  as the  case  may be,  and a
successor  depository  is not  appointed  by the Company  within 90 days of such
notice  or (ii) an Event of  Default  has  occurred  and is  continuing  and the
Registrar has received a request to the foregoing  effect from the Depository or
the Trustee.

         (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 the
other Global Note will,  upon  transfer,  cease to be an interest in such Global
Note and become an interest  in the 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  pursuant to paragraph (b) of this
Section 2.07 of a portion of the beneficial  interests in a Restricted Global or
Regulation S Global to beneficial  owners who are required to hold  Certificated
Notes,  the  Registrar  shall  reflect on its books and  records  the date and a
decrease in the  principal  amount of such  Restricted  Global or  Regulation  S
Global in an amount equal to the principal amount of the beneficial  interest in
such Restricted Global or Regulation S Global to be transferred, and the Company
shall execute,  and the Trustee shall authenticate and deliver, one or more U.S.
Certificated  Notes or Regulation S Certificated  Notes,  as the case may be, of
like tenor and amount.

         (e) In connection with the transfer of all the beneficial  interests in
a Restricted  Global or  Regulation S Global to  beneficial  owners  pursuant to
paragraph  (b) of this  Section  2.07,  the  Restricted  Global or  Regulation S
Global, 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 Depository in exchange
for its beneficial  interest in the Restricted Global or Regulation S Global, as
the case may be, an equal aggregate principal amount of U.S.  Certificated Notes
or  Regulation  S  Certificated  Notes,  as  the  case  may  be,  of  authorized
denominations.

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


<PAGE>

         (g) Any  Regulation S  Certificated  Note  delivered in exchange for an
interest in a Regulation S Global  pursuant to paragraph (b), (d) or (e) of this
Section 2.07 shall, except as otherwise provided by paragraphs (f)(i)(x) and (d)
of  Section  2.08  hereof,  bear  the  legend  regarding  transfer  restrictions
applicable  to the  Regulation  S  Certificated  Note set forth in Section  2.02
hereof.

         (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.

         (i) QIBs that are  beneficial  owners of interests in a Global Note may
receive  Certificated  Notes (which shall bear the Private  Placement  Legend if
required by Section 2.02) in accordance  with the procedures of the  Depository.
In  connection  with  the  execution,   authentication   and  delivery  of  such
Certificated  Notes,  the  Registrar  shall  reflect on its books and  records a
decrease  in the  principal  amount of the  relevant  Global  Note  equal to the
principal  amount of such  Certificated  Notes and the Company shall execute and
the Trustee shall authenticate and deliver one or more Certificated Notes having
an equal aggregate principal amount.

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

         SECTION 2.08. Special Transfer  Provisions.  Unless and until a Note is
exchanged  for an Exchange  Note in  connection  with an effective  Registration
Statement  pursuant  to  the  Registration   Rights  Agreement,   the  following
provisions shall apply:

         (a)  Transfers  to QIBs.  The  following  provisions  shall  apply with
respect to the registration of any proposed transfer of a U.S. Certificated Note
or an interest in a Restricted Global to a QIB (excluding Non-U.S. Persons):

         (i) If the Note to be  transferred  consists  of (x) U.S.  Certificated
    Notes,  the Registrar  shall register the transfer if such transfer is being
    made by a proposed  transferor  who has checked the box  provided for on 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 a QIB within the meaning of Rule 144A,  and
    is aware  that the 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 a  Restricted,  the  transfer of
    such interest may be effected only through the book-entry  system maintained
    by the Depository.


<PAGE>

         (ii) If the proposed  transferee is an Agent Member, and the Note to be
    transferred  consists  of  U.S.  Certificated  Notes,  upon  receipt  by the
    Registrar of the documents  referred to in clause (i) and instructions given
    in accordance  with the  Depository'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 such  Restricted  Global in an amount equal to the
    principal amount of the U.S.  Certificated Notes to be transferred,  and the
    Trustee shall cancel the Certificated Note so transferred.

         (b)  Transfers  of Interests  in  Regulation  S Global or  Regulation S
Certificated  Notes to U.S. Persons.  The following  provisions shall apply with
respect to any transfer of  interests  in a Regulation S Global or  Regulation S
Certificated Notes to U.S. Persons:

         (i)  prior  to the  removal  of the  Private  Placement  Legend  from a
    Regulation S Global or a Regulation S Certificated  Note pursuant to Section
    2.02, the Registrar shall refuse to register such transfer; and

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

         (c) 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.  Certificated  Note or an
    interest  in  a  Restricted  Global  only  upon  receipt  of  a  certificate
    substantially in the form of Exhibit E from the proposed transferor.

         (ii) (a) If the  proposed  transferor  is an  Agent  Member  holding  a
    beneficial interest in a Restricted Global, upon receipt by the Registrar of
    (x)  the  documents  required  by  paragraph  (i) and  (y)  instructions  in
    accordance  with  the  Depository'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 such  Restricted  Global in an amount equal to the
    principal amount of the beneficial  interest in the Restricted  Global 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
    Depository'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
    such  Regulation S Global in an amount equal to the principal  amount of the
    U.S.  Certificated Notes or the Restricted Global, as the case may be, to be
    transferred,  and the Trustee shall cancel the Certificated Note, if any, so
    transferred or decrease the amount of the Restricted Global.

         (d)  Private  Placement  Legend.  Upon the  registration  of  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 registration of transfer,  exchange or replacement of Notes bearing the
Private Placement  Legend,  the Registrar shall deliver only Notes that bear the
Private  Placement  Legend unless either (i) the Private  Placement Legend is no
longer  required by Section 2.02 or (ii) there is delivered to the  Registrar an

<PAGE>

Opinion of Counsel reasonably satisfactory to the Company and the Trustee to the
effect that  neither  such legend nor the related  restrictions  on transfer are
required in order to maintain  compliance  with the provisions of the Securities
Act.

         (e)  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 to an  Institutional
Accredited  Investor,  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,   in  accordance   with  its  customary
procedures,  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.

         (f)  Transfers  to  Non-QIB  Institutional  Accredited  Investors.  The
following  provisions  shall  apply  with  respect  to the  registration  of any
proposed  transfer of a Note to any Institutional  Accredited  Investor which is
not a QIB (excluding Non-U.S. Persons):

         (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 as in  effect  with  respect  to  such  transfer  or (y) the
    proposed  transferee  has  delivered  to  the  Registrar  (A) a  certificate
    substantially  in the  form of  Exhibit  F hereto  and (B) if the  aggregate
    principal amount of the Notes being transferred is less than $100,000 at the
    time of such transfer,  an Opinion of Counsel 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 a  Restricted  Global,  upon  receipt by the  Registrar  and the
    Company of (x) the  documents,  if any,  required by  paragraph  (i) and (y)
    instructions  given in accordance with the  Depository'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 such  Restricted  Global in an
    amount  equal to the  principal  amount of the  beneficial  interest  in the
    Restricted Global to be transferred,  and the Company shall execute, and the
    Trustee shall authenticate and deliver, one or more U.S.  Certificated Notes
    of like tenor and amount.


<PAGE>

         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, 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 and the  second  paragraph  of Section  2.10 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
reasonably  satisfactory  to them that the replaced  Note is held by a bona fide
purchaser.

         If the Paying  Agent  (other  than the Company or an  Affiliate  of the
Company) holds on the maturity date or a redemption date money sufficient to pay
all principal,  premium,  if any, and interest payable on that date with respect
to the Notes (or portions  thereof) to be redeemed or 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 knows 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 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

<PAGE>

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
registration  of  transfer,  exchange,  purchase or payment.  The Trustee  shall
cancel all Notes surrendered for registration of transfer,  exchange,  purchase,
payment or  cancellation  and shall  return all such Notes to the  Company.  The
Company  shall not issue Notes to replace Notes it has paid in full or delivered
to the Trustee for cancellation.

         SECTION 2.13.  CUSIP Numbers.  The Company in issuing the Notes may use
"CUSIP," "CINS," or "ISIN" numbers,  or common codes (if then generally in use),
as the case may be, in notices of  redemption  or 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  redemption  or exchange  and that  reliance  may be
placed  only on the other  identification  numbers  printed  on the  Notes.  The
Company shall  promptly  advise the Trustee of any change in the CUSIP,  CINS or
ISIN numbers or common codes for the Notes.

         SECTION 2.14. Defaulted Interest.  If the Company defaults in a payment
of interest on the Notes,  it shall pay, or shall  deposit with the Paying Agent
money in immediately  available funds sufficient to pay, the defaulted interest,
plus (to the extent lawful) interest on the defaulted  interest,  to the Persons
who are Holders on a subsequent  special  record date. A special record date, as
used in this Section 2.14 with respect to the payment of any defaulted interest,
shall mean the 15th day next  preceding  the date fixed by the  Company  for the
payment of  defaulted  interest,  whether or not such day is a Business  Day. At
least 15 days before the subsequent  special record date, the Company shall mail
to each Holder and to the Trustee a notice  that states the  subsequent  special
record date, the payment date and the amount of defaulted interest to be paid.

         SECTION 2.15. Issuance of Additional Notes. The Company may, subject to
Article Four of this Indenture, issue additional Notes under this Indenture. All
Notes issued  pursuant to this Indenture  shall be treated as a single class for
all purposes under this Indenture.

         SECTION  3.01.  Right of  Redemption.  The Notes may be redeemed at the
election of the Company,  in whole or in part, at any time and from time to time
on or after March 15, 2004 and prior to maturity, upon not less than 30 nor more
than 60 days' prior notice  mailed by  first-class  mail to each  Holder's  last
address as it appears in the Note Register,  at the following  Redemption Prices
(expressed in percentages of their  principal  amount),  plus accrued and unpaid
interest,  if any, to the  Redemption  Date  (subject to the right of Holders of
record on the relevant Regular Record Date that is on or prior to the Redemption
Date to receive interest due on an Interest Payment Date) if redeemed during the
12-month period commencing on March 15 of the applicable year set forth below:


Year                                                            Redemption Price
- ----                                                            ----------------

2004..................................................                  105.750%
2005..................................................                  103.833%
2006..................................................                  101.917%
2007 and thereafter...................................                  100.000%


         (b) In addition,  at any time prior to March 15, 2002, the Company may,
at its option,  redeem up to 35% of the aggregate  principal amount of the Notes
with the net  proceeds of one or more Public  Equity  Offerings,  at any time or
from time to time in part, at a Redemption  Price  (expressed as a percentage of
the principal amount) of 111.500%, provided (i) that Notes representing at least
65% of the principal  amount of the Notes  initially  issued remain  outstanding
immediately  after  each  such  redemption  and (ii)  that  notice  of each such
redemption is mailed within 60 days of each such Public Equity Offering.

         SECTION 3.02. Notices to Trustee. If the Company elects to redeem Notes
pursuant  to  Section  3.01,  it shall  notify  the  Trustee  in  writing of the
Redemption Date and the principal amount of Notes to be redeemed.

         The Company shall give each notice provided for in this Section 3.02 in
an Officers'  Certificate at least 45 days before the Redemption  Date (unless a
shorter period shall be satisfactory to the Trustee).

         SECTION  3.03.  Selection of Notes to Be Redeemed.  If less than all of
the Notes are to be redeemed at any time,  the Trustee shall select the Notes to
be  redeemed in  compliance  with the  requirements  of the  principal  national
securities  exchange,  if any, on which the Notes are listed or if the Notes are
not listed on a national securities exchange,  by lot or by such other method as
the  Trustee  in its sole  discretion  shall  deem to be fair  and  appropriate;
provided  that no Notes of $1,000 in principal  amount or less shall be redeemed
in part.

         The Trustee shall make the selection from the Notes outstanding and not
previously called for redemption.  Notes in denominations of $1,000 in principal
amount may only be  redeemed in whole.  The  Trustee  may select for  redemption
portions (equal to $1,000 in principal amount or any integral  multiple thereof)
of Notes  that  have  denominations  larger  than  $1,000 in  principal  amount.
Provisions  of this  Indenture  that apply to Notes called for  redemption  also

<PAGE>

apply to portions of Notes called for  redemption.  The Trustee shall notify the
Company and the Registrar  promptly in writing of the Notes or portions of Notes
to be called for redemption.

         SECTION 3.04.  Notice of Redemption.  With respect to any redemption of
Notes  pursuant  to  Section  3.01,  at least 30 days but not more  than 60 days
before a Redemption Date, the Company,  or at the Company's request the Trustee,
shall mail a notice of redemption by first class mail to each Holder whose Notes
are to be redeemed.

         The notice shall identify the Notes to be redeemed and shall state:

         (i) the Redemption Date;

         (ii) the Redemption Price;

         (iii) the name and address of the Paying Agent;

         (iv) that Notes called for redemption must be surrendered to the Paying
    Agent in order to collect the Redemption Price;

         (v) that, unless the Company defaults in making the redemption payment,
    interest on Notes (or  portions  thereof)  called for  redemption  ceases to
    accrue on and after the Redemption  Date and the only remaining right of the
    Holders is to receive payment of the Redemption  Price plus accrued interest
    to the Redemption Date upon surrender of the Notes to the Paying Agent;

         (vi) that,  if any Note is being  redeemed in part,  the portion of the
    principal  amount  (equal  to  $1,000 in  principal  amount or any  integral
    multiple  thereof)  of such Note to be redeemed  and that,  on and after the
    Redemption  Date,  upon  surrender  of such  Note,  a new  Note or  Notes in
    principal amount equal to the unredeemed portion thereof,  will be reissued;
    and

         (vii)  that,  if any Note  contains a CUSIP,  CINS or ISIN  number or a
    common code, as provided in Section 2.13, no representation is being made as
    to the  correctness  of the CUSIP,  CINS or ISIN  number or the common  code
    either as printed on the Notes or as contained in the notice of redemption.

At the  Company's  request  (which  request may be revoked by the Company at any
time prior to the time at which the Trustee  shall have given such notice to the
Holders),  made in  writing  to the  Trustee  at least 45 days (or such  shorter
period as shall be satisfactory  to the Trustee)  before a Redemption  Date, the
Trustee  shall give the notice of  redemption  in the name and at the expense of
the Company.  If,  however,  the Company  gives such notice to the Holders,  the
Company  shall  concurrently  deliver  to the  Trustee a copy of such  notice of
redemption.

         SECTION 3.05. Effect of Notice of Redemption. Once notice of redemption
is mailed,  Notes called for redemption become due and payable on the Redemption
Date and at the  Redemption  Price.  Upon  surrender  of any Notes to the Paying
Agent,  such Notes shall be paid at the Redemption Price, plus accrued interest,
if any, to the Redemption Date. Notice of redemption shall be deemed to be given

<PAGE>

when  mailed,  whether  or not the Holder  receives  the  notice.  In any event,
failure  to give such  notice,  or any  defect  therein,  shall not  affect  the
validity of the  proceedings for the redemption of Notes held by Holders to whom
such notice was properly given.

         SECTION  3.06.  Deposit  of  Redemption  Price.  On  or  prior  to  any
Redemption  Date,  the Company  shall  deposit with the Paying Agent (or, if the
Company,  one of its Subsidiaries or any of their Affiliates is acting as Paying
Agent,  shall  segregate  and hold in trust as provided  in Section  2.05) money
sufficient to pay the Redemption  Price of and accrued  interest on all Notes to
be  redeemed  on that date  other  than  Notes or  portions  thereof  called for
redemption  on that date that have been  delivered by the Company to the Trustee
for cancellation.

         SECTION  3.07.  Payment of Notes  Called for  Redemption.  If notice of
redemption has been given in the manner provided above,  the Notes or portion of
Notes  specified  in such notice to be redeemed  shall become due and payable on
the  Redemption  Date at the  Redemption  Price stated  therein,  together  with
accrued interest to such Redemption Date, and on and after such date (unless the
Company shall default in the payment of such Notes at the  Redemption  Price and
accrued  interest to the  Redemption  Date, in which case the  principal,  until
paid, shall bear interest from the Redemption Date at the rate prescribed in the
Notes),  such Notes shall cease to accrue  interest.  Upon surrender of any Note
for  redemption in accordance  with a notice of  redemption,  such Note shall be
paid and redeemed by the Company at the Redemption Price,  together with accrued
interest, if any, to the Redemption Date; provided that installments of interest
whose Stated  Maturity is on or prior to the Redemption Date shall be payable to
the Holders  registered as such at the close of business on the relevant Regular
Record Date.

         SECTION 3.08.  Notes Redeemed in Part.  Upon surrender of any Note that
is  redeemed  in  part,   the  Company  shall  execute  and  the  Trustee  shall
authenticate  and deliver to the Holder a new Note equal in principal  amount to
the unredeemed portion of such surrendered Note.

                                    COVENANTS

         SECTION 4.01. Payment of Notes. The Company shall pay the principal of,
premium,  if any,  and  interest  on the Notes on the  dates  and in the  manner
provided in the Notes and this Indenture. An installment of principal,  premium,
if any, 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,
premium,  if any, 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 6.09,  upon any  bankruptcy or  reorganization  procedure
relative  to the  Company,  the  Trustee  shall  serve as the  Paying  Agent and
conversion agent, if any, for the Notes.

         The Company shall pay interest on overdue principal,  premium,  if any,
and interest on overdue  installments of interest,  to the extent lawful, at the
rate per annum specified in the Notes.


<PAGE>

         SECTION  4.02.  Maintenance  of  Office or  Agency.  The  Company  will
maintain an office or agency in the Borough of Manhattan,  the City of New York,
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
hereof.

         The  Company  may also from time to time  designate  one or more  other
offices or agencies  (in or outside the City of New York) 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 will give prompt written  notice to the Trustee of any such  designation
or  rescission  and of any change in the  location  of any such other  office or
agency.

         The Company hereby  initially  designates the Corporate Trust Office of
the Trustee,  located in the Borough of Manhattan, the City of New York, as such
office of the Company in accordance with Section 2.04.

         SECTION 4.03. Limitation on Indebtedness. (a) The Company will not, and
will not permit any of its Restricted  Subsidiaries  to, Incur any  Indebtedness
(other  than  the  Notes,  the  Senior  Dollar  Notes  and the  Euro  Notes  and
Indebtedness  existing on the Closing Date); provided that the Company may Incur
Indebtedness if, after giving effect to the Incurrence of such  Indebtedness and
the receipt and application of the proceeds therefrom, the Consolidated Leverage
Ratio would be greater than zero and less than 6:1.

         Notwithstanding   the   foregoing,   the  Company  and  any  Restricted
Subsidiary (except as specified below) may Incur each and all of the following:

(i)      Indebtedness  outstanding at any time in an aggregate  principal amount
         not to exceed $100 million of  Indebtedness  that is pari passu with or
         subordinated  to the Notes and $150  million  of  Indebtedness  that is
         subordinated  to the  Notes,  less  any  amount  of  such  Indebtedness
         permanently repaid as provided under Section 4.11 hereof;

(ii)     Indebtedness  owed (A) by any  Restricted  Subsidiary to the Company or
         another  Restricted  Subsidiary or (B) by the Company to any Restricted
         Subsidiary;   provided  that  any  event  which  results  in  any  such
         Restricted  Subsidiary  ceasing to be a  Restricted  Subsidiary  or any
         subsequent  transfer of such Indebtedness (other than to the Company or
         another  Restricted  Subsidiary)  shall be  deemed,  in each  case,  to
         constitute  an Incurrence  of such  Indebtedness  not permitted by this
         clause (ii);

(iii)    Indebtedness  issued in exchange  for, or the net proceeds of which are
         used to repay,  redeem,  defease,  refinance,  refund,  extend,  renew,
         replace,   discharge   or   otherwise   retire  any  then   outstanding
         Indebtedness (other than Indebtedness  Incurred under clause (i), (ii),

<PAGE>

         (iv),  (vi),  (viii),   (xi)  or  (xii)  of  this  paragraph)  and  any
         refinancings  thereof  in  an  amount  not  to  exceed  the  amount  so
         refinanced or refunded (plus  premiums,  penalties,  accrued  interest,
         fees and expenses);  provided that  Indebtedness  the proceeds of which
         are used to refinance or refund the Notes or Indebtedness  that is pari
         passu  with,  or  subordinated  in right of payment to, the Notes shall
         only be permitted  under this clause (iii) if (A) in case the Notes are
         refinanced in part or the  Indebtedness  to be refinanced is pari passu
         with the Notes, such new Indebtedness,  by its terms or by the terms of
         any agreement or instrument  pursuant to which such new Indebtedness is
         outstanding, is expressly made pari passu with, or subordinate in right
         of payment to, the remaining  Notes, (B) in case the Indebtedness to be
         refinanced is subordinated  in right of payment to the Notes,  such new
         Indebtedness,  by  its  terms  or by the  terms  of  any  agreement  or
         instrument pursuant to which such new Indebtedness is issued or remains
         outstanding,  is expressly made  subordinate in right of payment to the
         Notes at least to the extent that the  Indebtedness to be refinanced is
         subordinated to the Notes and (C) such new Indebtedness,  determined as
         of the date of  Incurrence  of such new  Indebtedness,  does not mature
         prior to the Stated  Maturity of the  Indebtedness  to be refinanced or
         refunded,  and the Average  Life of such new  Indebtedness  is at least
         equal  to  the  remaining  Average  Life  of  the  Indebtedness  to  be
         refinanced  or  refunded;  and  provided  further  that in no event may
         Indebtedness of the Company be refinanced by means of any  Indebtedness
         of any Restricted Subsidiary pursuant to this clause (iii);

(iv)     Indebtedness  (A) in respect  of  performance,  surety or appeal  bonds
         provided  in the  ordinary  course  of  business,  (B)  under  Currency
         Agreements and Interest Rate Agreements;  provided that such agreements
         (a) are designed solely to protect the Company or any of its Restricted
         Subsidiaries against fluctuations in foreign currency exchange rates or
         interest rates and (b) do not increase the  Indebtedness of the obligor
         outstanding  at any time  other  than as a result  of  fluctuations  in
         foreign currency exchange rates or interest rates or by reason of fees,
         indemnities and compensation  payable thereunder,  and (C) arising from
         agreements providing for indemnification,  adjustment of purchase price
         or similar obligations, or from Guarantees or letters of credit, surety
         bonds or performance  bonds securing any  obligations of the Company or
         any of its Restricted Subsidiaries pursuant to such agreements,  in any
         case  Incurred in  connection  with the  disposition  of any  business,
         assets or Restricted  Subsidiary (other than Guarantees of Indebtedness
         Incurred by any Person  acquiring all or any portion of such  business,
         assets or  Restricted  Subsidiary  for the  purpose of  financing  such
         acquisition),  in a principal  amount not to exceed the gross  proceeds
         actually  received  by the  Company  or any  Restricted  Subsidiary  in
         connection with such disposition;

(v)      Indebtedness of the Company, to the extent the net proceeds thereof are
         promptly  (A) used to purchase  Notes  tendered in an Offer to Purchase
         made as a result of a Change in Control or (B) deposited to defease the
         Notes as described below under Article Eight hereof;


<PAGE>

(vi)     Guarantees of the Notes and Guarantees of  Indebtedness  of the Company
         by  any   Restricted   Subsidiary   provided  the   Guarantee  of  such
         Indebtedness  is permitted by and made in accordance  with Section 4.07
         hereof;

(vii)    Indebtedness  (including  Guarantees)  Incurred  to  finance  the  cost
         (including the cost of design, development, acquisition,  construction,

         equipment,  inventory or network assets (including  acquisitions by way
         of Capitalized  Lease and acquisitions of the Capital Stock of a Person
         that becomes a Restricted  Subsidiary  to the extent of the fair market

         Company or a Restricted Subsidiary after the Closing Date;

(viii)   Indebtedness of the Company not to exceed, at any one time outstanding,
         two times (A) the Net Cash  Proceeds  received by the Company after the

         its Capital Stock (other than  Disqualified  Stock) to a Person that is
         not a  Subsidiary  of the  Company,  to the  extent  (I)  such  capital
         contribution or Net Cash Proceeds have not been used pursuant to clause
         (C)(2) of the first  paragraph or clause (iii),  (iv), (vi) or (vii) of
         the  second  paragraph  of  Section  4.04  hereof to make a  Restricted
         Payment and (II) if such capital  contribution or Net Cash Proceeds are
         used to consummate a transaction  pursuant to which the Company  Incurs
         Acquired  Indebtedness,  the amount of such Net Cash  Proceeds  exceeds
         one-half of the amount of Acquired Indebtedness so Incurred and (B) 80%
         of the  fair  market  value  of  property  (other  than  cash  and cash
         equivalents)  received by the Company  after the Closing  Date from the
         sale of its Capital Stock (other than  Disqualified  Stock) to a Person
         that is not a Subsidiary of the Company, to the extent (I) such capital
         contribution  or sale of Capital  Stock has not been used  pursuant  to

         fair market  value of the  property  received  exceeds  one-half of the
         amount  of  Acquired   Indebtedness  so  Incurred  provided  that  such
         Indebtedness  does not mature prior to the Stated Maturity of the Notes
         and has an Average Life longer than the Notes;

         the ordinary  course of business,  provided that such  Indebtedness  is
         extinguished within three Business Days of Incurrence.

maximum amount of Indebtedness  that the Company or a Restricted  Subsidiary may
Incur  pursuant to this Section  4.03 shall not be deemed to be  exceeded,  with
respect to any outstanding Indebtedness due solely to the result of fluctuations
in the exchange rates of currencies.

under this Section 4.03, (1)  Guarantees,  Liens or obligations  with respect to

determination of such particular  amount shall not be included and (2) any Liens
granted pursuant to the equal and ratable provisions referred to in Section 4.09

such clauses.

         (i) (A) declare or pay any dividend or make any distribution on or with
    respect to its Capital  Stock  (other than (1)  dividends  or  distributions

    Restricted Subsidiaries held by minority stockholders) held by Persons other
    than the Company or any of its Restricted  Subsidiaries  or (B) pay any cash

    right of payment to the Notes or

         (iv)  make any  Investment  (after  the  Closing  Date),  other  than a
    Permitted  Investment,  in any Person  (such  payments or any other  actions
    described in clauses (i) through (iv) above being  collectively  "Restricted
    Payments")

if, at the time of, and after giving effect to, the proposed Restricted Payment:
(A) a Default or Event of Default shall have occurred and be continuing, (B) the
Company could not Incur at least $1.00 of Indebtedness under the first paragraph
of Section 4.03 hereof or (C) the aggregate  amount of all  Restricted  Payments
(the amount,  if other than in cash, to be determined in good faith by the Board
of Directors,  whose  determination shall be conclusive and evidenced by a Board

<PAGE>

Resolution)  made after the Closing  Date shall exceed the sum of (1) 50% of the
aggregate  amount of the Adjusted  Consolidated  Net Income (or, if the Adjusted
Consolidated  Net  Income is a loss,  minus  100% of the  amount  of such  loss)
(determined  by  excluding  income  resulting  from  transfers  of assets by the
Company or a Restricted  Subsidiary to an Unrestricted  Subsidiary) accrued on a
cumulative basis during the period (taken as one accounting period) beginning on
the first day of the fiscal quarter  immediately  following the Closing Date and
ending on the last day of the last fiscal quarter preceding the Transaction Date
for which reports have been filed with the Commission or provided to the Trustee
pursuant  to  Section  4.18  hereof  plus (2) the  aggregate  Net Cash  Proceeds
received by the Company after the Closing Date as a capital contribution or from
the issuance and sale  permitted by this  Indenture of its Capital  Stock (other
than  Disqualified  Stock) to a Person who is not a  Subsidiary  of the Company,
including an issuance or sale permitted by this Indenture of Indebtedness of the
Company for cash  subsequent  to the Closing  Date upon the  conversion  of such
Indebtedness into Capital Stock (other than Disqualified  Stock) of the Company,
or from the issuance to a Person who is not a  Subsidiary  of the Company of any
options,  warrants or other rights to acquire  Capital  Stock of the Company (in
each case, exclusive of any Disqualified Stock or any options, warrants or other
rights that are  redeemable  at the option of the holder,  or are required to be
redeemed, prior to the Stated Maturity of the Notes), in each case except to the
extent such Net Cash Proceeds are used to Incur Indebtedness  pursuant to clause
(viii) of the second  paragraph  under  Section 4.03 hereof,  plus (3) an amount
equal to the net reduction in  Investments  (other than  reductions in Permitted
Investments) in any Person  resulting from payments of interest on Indebtedness,
dividends,  repayments of loans or advances,  or other  transfers of assets,  in
each  case to the  Company  or any  Restricted  Subsidiary  or from the Net Cash
Proceeds from the return of capital,  redemption, or sale of any such Investment
(except,  in each case,  to the extent any such payment or proceeds are included
in the calculation of Adjusted  Consolidated Net Income), or from redesignations
of Unrestricted  Subsidiaries as Restricted Subsidiaries (valued in each case as
provided  in the  definition  of  "Investments"),  or from  the  release  of any
Guarantee that constituted a Restricted  Payment, to the extent of such release,
not to exceed,  in each case, the amount of Investments  previously  made by the
Company or any Restricted Subsidiary in such Person or Unrestricted Subsidiary.

         The foregoing provision shall not be violated by reason of:

         (i)    the  payment of any  dividend within 60 days  after  the date of
    declaration  thereof if, at said date of  declaration,  such  payment  would
    comply with the foregoing paragraph;

         (ii)   the  redemption, repurchase, defeasance or other  acquisition or

    interest,  with the proceeds of, or in exchange for,  Indebtedness  Incurred
    under  clause  (iii) of the second  paragraph  of part (a) of  Section  4.03
    hereof;

         (iii)  the repurchase, redemption or other acquisition of Capital Stock
    of the Company or an Unrestricted Subsidiary (or options,  warrants or other

<PAGE>

    of, shares of Capital Stock (other than  Disqualified  Stock) of the Company
    (or options, warrants or other rights to acquire such Capital Stock);

         (iv)   the  making  of  any  principal   payment  or  the   repurchase,
    redemption,  retirement,  defeasance  or  other   acquisition for  value  of
    Indebtedness of the Company which is subordinated in right of payment to the
    Notes in exchange for, or out of the  proceeds of a capital contribution  or
    a  substantially concurrent offering of,  shares of the Capital Stock (other
    than  Disqualified  Stock) of  the Company (or  options,  warrants  or other
    rights to acquire such Capital Stock);

         (v)    payments or distributions to dissenting stockholders pursuant to
    applicable law, pursuant to or in connection with a consolidation, merger or
    transfer of assets that complies with the provisions of Article Five hereof;

         (vi)   Investments  in any Person  the  primary  business  of  which is
    related, ancillary or complementary to the business of the Company or any of
    its Restricted  Subsidiaries on the date of such Investments;  provided that
    the aggregate  amount of Investments  made pursuant to this clause (vi) does
    not exceed $30 million at any one time outstanding;

         (vii)  Investments acquired in  exchange for Capital  Stock (other than
    Disqualified  Stock)  of the  Company  or the Net  Cash  Proceeds  from  the
    issuance and sale of such Capital Stock,  provided that such proceeds are so
    used within 180 days of the receipt thereof;

         (viii) the redemption,  repurchase,  retirement or other acquisition of
    any Capital  Stock of the Company (or  options,  warrants or other rights to
    acquire  such  Capital  Stock) from an  employee  or former  employee of the
    Company or any of its Subsidiaries  (or from such person's estate,  heirs or
    representatives)  in connection  with such employee's  death,  disability or
    termination  of  employment,  provided  that the aggregate  amount  expended
    pursuant  to this  clause  does not  exceed $1  million  per annum  plus the
    cumulative  amount of such per annum  limit not used in prior  years and the
    cash  proceeds from such  Investments,  provided that such proceeds are used
    within 180 days of the receipt thereof;

         (ix)   Investments  in permitted  Wholesale  Consortiums  and Permitted
    Joint Ventures not exceeding, at the time of the  Investment, the sum of (A)
    10% of the consolidated  revenue of  the Company  (excluding with respect to
    Persons in whom  an  equity  interest  is owned  by Persons  other  than the
    Company and its Restricted Subsidiaries, the pro  rata share of such revenue
    attributable to such other  equity  holders)  accrued on a cumulative  basis
    during the period (taken as one  accounting  period)  beginning on the first
    day of the first full fiscal quarter immediately  following the Closing Date
    and ending on the  last  day of the  last fiscal quarter  preceding the date
    of such Investment  and  (B) the Net  Cash  Proceeds  from  the  disposition
    of the  Company's  interest in  any such Permitted  Wholesale  Consortium or
    Permitted Joint Venture;

         (x)    the  repurchase of Subordinated  Convertible  Debentures  upon a
    Change of Control  pursuant to an Offer to Purchase;  provided that an Offer
    to Purchase is consummated with respect to the Notes prior to any repurchase
    of the Subordinated Debentures; and


<PAGE>

         (xi)   other  Restricted  Payments in an aggregate amount not to exceed
    $10 million, increased by the amount of any Restricted Payment made pursuant
    to this clause (xiii) that is an Investment and is not outstanding;

provided that,  except in the case of clauses (i) and (iii), no Default or Event
of Default shall have  occurred and be  continuing or occur as a consequence  of
the actions or payments set forth therein.

         Each Restricted Payment permitted  pursuant to the preceding  paragraph
(other  than the  Restricted  Payment  referred to in clause  (ii)  thereof,  an
exchange  of Capital  Stock for  Capital  Stock or  Indebtedness  referred to in
clause  (iii) or (iv)  thereof  and an  Investment  referred  to in clause  (vi)
thereof),  and the Net  Cash  Proceeds  from  any  capital  contribution  or any
issuance of Capital Stock referred to in clauses (iii),  (iv) and (vi), shall be
included  in  calculating  whether  the  conditions  of clause  (C) of the first
paragraph  of this  Section  4.04 have been met with  respect to any  subsequent
Restricted  Payments.  In the event the proceeds of an issuance of Capital Stock
of the Company are used for the redemption,  repurchase or other  acquisition of
the Notes, or Indebtedness  that is pari passu with the Notes, then the Net Cash
Proceeds of such issuance shall be included in clause (C) of the first paragraph
of this  Section  4.04 only to the extent  such  proceeds  are not used for such
redemption, repurchase or other acquisition of Indebtedness.

         Any Restricted Payments made in other than cash shall be valued at fair
market value.  The amount of any Investment  "outstanding"  at any time shall be
deemed to be equal to the amount of such  Investment on the date made,  less the
return  of  capital,  repayment  of loans,  return on  capital  and  release  of
Guarantees,  in each case of or to the Company and its  Restricted  Subsidiaries
with respect to such Investment (up to the amount of such investment on the date
made).

         SECTION 4.05.  Limitation  on Dividend and Other  Payment  Restrictions
Affecting Restricted Subsidiaries. The Company will not, and will not permit any
Restricted Subsidiary to, create or otherwise cause or suffer to exist or become
effective any  consensual  encumbrance or restriction of any kind on the ability
of  any   Restricted   Subsidiary  to  (i)  pay  dividends  or  make  any  other
distributions  permitted  by  applicable  law  on  any  Capital  Stock  of  such
Restricted  Subsidiary owned by the Company or any other Restricted  Subsidiary,
(ii)  pay  any  Indebtedness  owed  to  the  Company  or  any  other  Restricted
Subsidiary,  (iii) make loans or advances to the Company or any other Restricted
Subsidiary  or (iv) transfer any of its property or assets to the Company or any
other Restricted Subsidiary.

         The  foregoing  provisions  shall  not  restrict  any  encumbrances  or
restrictions:

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


<PAGE>

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

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

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

         (v) with respect to a Restricted  Subsidiary and imposed pursuant to an
    agreement  that has been entered into for the sale or  disposition of all or
    substantially  all of the Capital  Stock of, or property and assets of, such
    Restricted Subsidiary;

         (vi)  contained  in the  terms  of any  Indebtedness  or any  agreement
    pursuant to which such  Indebtedness  was issued if (A) the  encumbrance  or
    restriction applies only in the event of a payment default or a default with
    respect to a financial covenant contained in such Indebtedness or agreement,
    (B) the encumbrance or restriction is not materially more disadvantageous to
    the Holders of the Notes than is  customary  in  comparable  financings  (as
    determined  by the  Company)  and (C) the Company  determines  that any such
    encumbrance or restriction will not materially  affect the Company's ability
    to make principal or interest payments on the Notes; or

         (vii) imposed in connection with a transaction  described in clause (f)
    of the proviso to the  definition  of "Asset Sale" and relating  solely to a
    Restricted  Subsidiary  that transfers  assets to the special purpose entity
    referred to therein;  provided  that the  Company  determines  that any such
    encumbrance or restriction will not materially  affect the Company's ability
    to make principal or interest payments on the Notes.

Nothing  contained  in this  Section  4.05  shall  prevent  the  Company  or any
Restricted  Subsidiary  from (1) creating,  incurring,  assuming or suffering to
exist any Liens  otherwise  permitted in Section 4.09 hereof or (2)  restricting
the sale or other disposition of property or assets of the Company or any of its
Restricted  Subsidiaries  that secure  Indebtedness of the Company or any of its
Restricted Subsidiaries.

         SECTION  4.06.  Limitation on the Issuance and Sale of Capital Stock of
Restricted  Subsidiaries.  The  Company  will not sell,  and will not permit any
Restricted Subsidiary,  directly or indirectly,  to issue or sell, any shares of
Capital Stock of a Restricted Subsidiary  (including options,  warrants or other
rights to purchase  shares of such Capital Stock) except (i) to the Company or a
Wholly-Owned  Restricted  Subsidiary;  (ii)  issuances of director's  qualifying
shares or sales to  foreign  nationals  of shares of  Capital  Stock of  foreign
Restricted  Subsidiaries,  to the extent  required by applicable  law; (iii) if,

<PAGE>

immediately  after  giving  effect to such  issuance  or sale,  such  Restricted
Subsidiary would no longer constitute a Restricted Subsidiary and any Investment
in such Person remaining after giving effect to such issuance or sale would have
been  permitted to be made under Section 4.04 hereof if made on the date of such
issuance or sale; (iv) a pledge or hypothecation of or Lien on any Capital Stock
of a Subsidiary to the extent not prohibited  under Section 4.09 hereof;  or (v)
sales by the Company or Restricted  Subsidiaries of Common Stock of a Restricted
Subsidiary,  provided that the Company or such Restricted Subsidiaries apply the
Net Cash Proceeds, if any, of any such sale in accordance with clause (A) or (B)
of Section 4.11 hereof.

         SECTION  4.07.  Limitation  on Issuances of  Guarantees  by  Restricted
Subsidiaries. The Company will not permit any Restricted Subsidiary, directly or
indirectly,  to Guarantee  any  Indebtedness  of the Company which is pari passu
with  or   subordinate   in  right  of   payment   to  the  Notes   ("Guaranteed
Indebtedness"),  unless (i) such Restricted Subsidiary  simultaneously  executes
and  delivers  a  supplemental  indenture  to  this  Indenture  providing  for a
Guarantee (a "Subsidiary  Guarantee") of payment of the Notes by such Restricted
Subsidiary  and (ii)  such  Restricted  Subsidiary  waives,  and will not in any
manner  whatsoever  claim or take the  benefit  or  advantage  of, any rights of
reimbursement,  indemnity or subrogation or any other rights against the Company
or any other Restricted Subsidiary as a result of any payment by such Restricted
Subsidiary  under its Subsidiary  Guarantee;  provided that this paragraph shall
not be applicable to any Guarantee of any Restricted  Subsidiary that existed at
the time such Person  became a  Restricted  Subsidiary  and was not  Incurred in
connection  with,  or in  contemplation  of, such Person  becoming a  Restricted
Subsidiary.  If the  Guaranteed  Indebtedness  is (A) pari passu with the Notes,
then the Guarantee of such Guaranteed  Indebtedness shall be pari passu with, or
subordinated to, the Subsidiary Guarantee or (B) subordinated to the Notes, then
the  Guarantee of such  Guaranteed  Indebtedness  shall be  subordinated  to the
Subsidiary Guarantee at least to the extent that the Guaranteed  Indebtedness is
subordinated to the Notes.

         Notwithstanding the foregoing, any Subsidiary Guarantee by a Restricted
Subsidiary  may  provide  by its  terms  that  it  shall  be  automatically  and
unconditionally released and discharged upon (i) any sale, exchange or transfer,
to any Person not an Affiliate of the Company,  of all of the Company's and each
Restricted Subsidiary's Capital Stock in, or all or substantially all the assets
of,  such  Restricted  Subsidiary  (which  sale,  exchange  or  transfer  is not
prohibited by this  Indenture) or (ii) the release or discharge of the Guarantee
which resulted in the creation of such Subsidiary Guarantee,  except a discharge
or release by or as a result of payment under such Guarantee.

         SECTION  4.08.   Limitation  on  Transactions   with  Shareholders  and
Affiliates.  The Company will not, and will not permit any Restricted Subsidiary
to,  directly  or  indirectly,  enter  into,  renew or  extend  any  transaction
(including,  without  limitation,  the  purchase,  sale,  lease or  exchange  of
property or assets,  or the  rendering of any  service)  with any holder (or any
Affiliate  of such  holder) of 5% or more of any class of  Capital  Stock of the
Company  or with any  Affiliate  of the  Company or any  Restricted  Subsidiary,
except upon fair and  reasonable  terms no less favorable to the Company or such
Restricted  Subsidiary than could be obtained,  at the time of such  transaction
or, if such transaction is pursuant to a written  agreement,  at the time of the
execution of the  agreement  providing  therefor,  in a comparable  arm's-length
transaction with a Person that is not such a holder or an Affiliate.


<PAGE>

         The foregoing limitation does not limit, and shall not apply to:

         (i)  transactions  (A)  approved  by a  majority  of the  disinterested
    members  of the  Board  of  Directors  or (B) for  which  the  Company  or a
    Restricted  Subsidiary  delivers  to the  Trustee  a  written  opinion  of a
    nationally  recognized  investment banking firm stating that the transaction
    is fair to the Company or such Restricted  Subsidiary from a financial point
    of view;

         (ii)  any  transaction  solely  between  the  Company  and  any  of its
    Restricted Subsidiaries or solely between Restricted Subsidiaries;

         (iii) the payment of reasonable and customary regular fees to directors
    of the Company who are not employees of the Company;

         (iv) any  payments or other  transactions  pursuant to any  tax-sharing
    agreement  between the  Company and any other  Person with which the Company
    files a  consolidated  tax  return or with  which the  Company  is part of a
    consolidated group for tax purposes;

         (v)  compensation,  indemnification  and  other  benefits  paid or made
    available to officers,  directors  and  employees in the ordinary  course of
    business in connection with services  actually  rendered and consistent with
    past practice;

         (vi)   transactions  in  accordance   with  the  Existing   Stockholder
    Agreements as in effect on the Closing Date; or

         (vii) any  Restricted  Payments not  prohibited by Section 4.04 hereof.
    Notwithstanding  the  foregoing,   any  transaction  or  series  of  related
    transactions  covered by the first  paragraph  of this  Section 4.08 and not
    covered by clauses (ii) through (v) of this paragraph,  the aggregate amount
    of which exceeds $2.0 million in value, must be approved or determined to be
    fair in the  manner  provided  for in clause  (i)(A) or (B) of this  Section
    4.08.

         SECTION 4.09.  Limitation on Liens.  The Company will not, and will not
permit any Restricted  Subsidiary to, create,  incur,  assume or suffer to exist
any Lien on any of its assets or properties of any character (including, without
limitation,  licenses),  or any shares of Capital Stock or  Indebtedness  of any
Restricted  Subsidiary,  without making effective provision for all of the Notes
and all other amounts due under this  Indenture to be directly  secured  equally
and ratably with (or, if the  obligation or liability to be secured by such Lien
is  subordinated  in right of payment to the Notes,  prior to) the obligation or
liability secured by such Lien.

         The foregoing limitation does not apply to:

         (i) Liens existing on the Closing Date;

         (ii)  Liens  granted  after the  Closing  Date on any assets or Capital
    Stock of the Company or its Restricted  Subsidiaries created in favor of the
    Holders;


<PAGE>

         (iii)  Liens  with  respect to the  assets of a  Restricted  Subsidiary
    granted by such  Restricted  Subsidiary  to the  Company  or a  Wholly-Owned
    Restricted  Subsidiary to secure  Indebtedness  owing to the Company or such
    other Restricted Subsidiary;

         (iv) Liens securing Indebtedness  permitted to be Incurred under clause
    (iii) of the second  paragraph  of Section  4.03 hereof which is Incurred to
    refinance secured Indebtedness; provided that such Liens do not extend to or
    cover any  property  or assets of the Company or any  Restricted  Subsidiary
    other  than  the  property  or  assets  securing  the   Indebtedness   being
    refinanced;

         (v) Liens on the  Capital  Stock of, or any  property  or assets  of, a
    Restricted  Subsidiary securing  Indebtedness of such Restricted  Subsidiary
    permitted under Section 4.03 hereof;

         (vi) Liens on the Capital Stock of Restricted  Subsidiaries  that own a
    substantial  portion of assets  financed with  Indebtedness  Incurred  under
    clause  (vii) of  Section  4.03  hereof,  if such  liens  secure  only  such
    Indebtedness; or

         (vii) Permitted Liens.

         SECTION 4.10.  Limitation on Sale-Leaseback  Transactions.  The Company
will not,  and will not  permit any  Restricted  Subsidiary  to,  enter into any
sale-leaseback transaction involving any of its assets or properties whether now
owned or  hereafter  acquired,  whereby the Company or a  Restricted  Subsidiary
sells or transfers such assets or properties and then or thereafter  leases such
assets or properties or any part thereof or any other assets or properties which
the Company or such  Restricted  Subsidiary,  as the case may be, intends to use
for  substantially the same purpose or purposes as the assets or properties sold
or transferred; provided that a sale-leaseback transaction shall not include any
lease in connection with which the Company or a Restricted  Subsidiary  acquires
assets or property in anticipation of the substantially  contemporaneous sale or
transfer to the lessor under such lease.

         The  foregoing   restriction  does  not  apply  to  any  sale-leaseback
transaction if:

         (i) the  lease is for a period,  including  renewal  rights,  of not in
    excess of three years;

         (ii) the lease  secures or relates to  industrial  revenue or pollution
    control bonds;

         (iii) the  transaction is solely between the Company and any Restricted
    Subsidiary or solely between Restricted Subsidiaries; or

         (iv) the Company or such Restricted Subsidiary,  within 12 months after
    the sale or transfer of any assets or properties  is  completed,  applies an
    amount not less than the net proceeds  received from such sale in accordance
    with clause (A) or (B) of the first paragraph of Section 4.11 hereof.


<PAGE>

         SECTION 4.11. Limitation on Asset Sales. The Company will not, and will
not permit any Restricted  Subsidiary to,  consummate any Asset Sale, unless (i)
the  consideration  received by the Company or such Restricted  Subsidiary is at
least equal to the fair market  value of the assets sold or disposed of and (ii)
at least 75% of the  consideration  received  consists of cash or Temporary Cash
Investments.  In the event and to the extent that the Net Cash Proceeds received
by the  Company  or any of its  Restricted  Subsidiaries  from one or more Asset
Sales  occurring  on or after the Closing  Date in any period of 12  consecutive
months exceed 10% of Adjusted Consolidated Net Tangible Assets (determined as of
the date  closest  to the  commencement  of such  12-month  period  for  which a
consolidated  balance sheet of the Company and its  Subsidiaries  has been filed
with the Commission pursuant to Section 4.18 hereof),  then the Company shall or
shall cause the relevant Restricted Subsidiary to (i) within 12 months after the
date Net Cash  Proceeds so  received  exceed 10% of  Adjusted  Consolidated  Net
Tangible  Assets,  (A) apply an amount equal to such excess Net Cash Proceeds to
permanently repay unsubordinated  Indebtedness of the Company, or any Restricted
Subsidiary  providing a Subsidiary  Guarantee pursuant to Section 4.07 hereof or
Indebtedness of any other Restricted Subsidiary,  in each case owing to a Person
other than the Company or any of its  Restricted  Subsidiaries  or (B) invest an
equal amount, or the amount not so applied pursuant to clause (A) (or enter into
a definitive  agreement  committing to so invest within 12 months after the date
of such agreement),  either in property or assets (other than current assets) of
a nature or type or that are used in a business, or in a company having property
and assets of a nature or type, or engaged in a business, in either case similar
or related to the nature or type of the  property and assets of, or the business
of, the Company or any of its  Restricted  Subsidiaries  existing on the date of
such  investment (as  determined in good faith by the Board of Directors,  whose
determination  shall be conclusive and evidenced by a Board Resolution) and (ii)
apply (no later than the end of the 12-month  period  referred to in clause (i))
such excess Net Cash Proceeds (to the extent not applied pursuant to clause (i))
as provided in the following  paragraph of this Section 4.11. The amount of such
excess Net Cash  Proceeds  required  to be  applied  (or to be  committed  to be
applied) during such 12-month period as set forth in clause (i) of the preceding
sentence  and  not  applied  as so  required  by the end of  such  period  shall
constitute "Excess Proceeds."

         If, as of the first day of any calendar month,  the aggregate amount of
Excess Proceeds not theretofore subject to an Offer to Purchase pursuant to this
Section 4.11 totals at least $10 million,  the Company must commence,  not later
than the  fifteenth  Business  Day of such  month,  and  consummate  an Offer to
Purchase from the Holders on a pro rata basis an aggregate  principal  amount of
Notes equal to the Excess  Proceeds on such date,  at a purchase  price equal to
101% of the principal amount of the Notes on the relevant Payment Date, plus, in
each case, accrued interest (if any) to the Payment Date.

         SECTION 4.12. Repurchase of Notes upon a Change of Control. The Company
must  commence,  within 30 days of the  occurrence  of a Change of Control,  and
consummate  an  Offer to  Purchase  for all the  Notes  then  outstanding,  at a
purchase  price  equal  to 101% of the  principal  amount  of the  Notes  on the
relevant Payment Date, plus accrued interest (if any) to the Payment Date.

         SECTION 4.13.  Existence.  Except as otherwise provided or permitted in
Articles  Four and Five of this  Indenture,  the Company  will do or cause to be
done all  things  necessary  to  preserve  and keep in full force and effect its
existence and the existence of each of its Restricted Subsidiaries in accordance
with the  respective  organizational  documents  of the  Company  and each  such

<PAGE>

Subsidiary  (as the same  may be  amended  from  time to  time)  and the  rights
(whether pursuant to charter,  partnership  certificate,  agreement,  statute or
otherwise),  material  licenses  and  franchises  of the  Company  and each such
Subsidiary; provided that the Company shall not be required to preserve any such
right, license or franchise,  or the existence of any Restricted Subsidiary,  if
the maintenance or preservation thereof is no longer desirable in the conduct of
the business of the Company and its Restricted Subsidiaries taken as a whole.

         SECTION 4.14.  Payment of Taxes and Other Claims.  The Company will pay
or discharge and shall cause each of its  Subsidiaries  to pay or discharge,  or
cause to be paid or discharged,  before the same shall become delinquent (i) all
material taxes,  assessments and governmental charges levied or imposed upon (a)
the  Company  or any such  Subsidiary,  (b) the  income or  profits  of any such
Subsidiary which is a corporation or (c) the property of the Company or any such
Subsidiary and (ii) all material lawful claims for labor, materials and supplies
that, if unpaid,  might by law become a Lien upon the property of the Company or
any such  Subsidiary;  provided that the Company shall not be required to pay or
discharge, or cause to be paid or discharged,  any such tax, assessment,  charge
or claim the amount,  applicability  or validity of which is being  contested in
good faith by appropriate  proceedings,  for which  adequate  reserves have been
established.

         SECTION 4.15. Maintenance of Properties and Insurance. The Company will
cause all  properties  used or  useful in the  conduct  of its  business  or the
business of any of its  Restricted  Subsidiaries,  to be maintained  and kept in
good  condition,  repair and working order (ordinary wear and tear excepted) and
supplied  with all  necessary  equipment and will cause to be made all necessary
repairs, renewals, replacements, betterments and improvements thereof, all as in
the judgment of the Company may be necessary so that the business  carried on in
connection therewith may be properly and advantageously  conducted at all times;
provided that nothing in this Section 4.15 shall prevent the Company or any such
Subsidiary from  discontinuing the use,  operation or maintenance of any of such
properties or disposing of any of them, if such  discontinuance  or disposal is,
in the judgment of the Company,  desirable in the conduct of the business of the
Company or such Subsidiary.

         The Company will  provide or cause to be  provided,  for itself and its
Restricted  Subsidiaries,   insurance  (including  appropriate   self-insurance)
against loss or damage of the kinds customarily  insured against by corporations
similarly  situated and owning like properties,  with reputable insurers or with
the government of the United States of America,  or an agency or instrumentality
thereof, in such amounts,  with such deductibles and by such methods as shall be

business.

and the principal financial officer of the Company shall certify, on or before a
date not more than 90 days  after the end of each  fiscal  year of the  Company,

Restricted  Subsidiaries  and the  Company's  and its  Restricted  Subsidiaries'
performance  under  this  Indenture  and  that the  Company  has  fulfilled  all

<PAGE>

obligations hereunder, or, if there has been a default in the fulfillment of any
such obligation, specifying each such default and the nature and status thereof.
The  Company  shall also  notify the  Trustee of any  default or defaults in the
performance  of any covenants or agreements  under this  Indenture.  The Company
shall also comply with the other provisions of Section 314(a) of the TIA.

         SECTION 4.18.  Commission Reports and Reports to Holders.  At all times
from and after the  earlier of (i) the date of the  commencement  of an Exchange
Offer   or  the   effectiveness   of  a  Shelf   Registration   Statement   (the
"Registration")  and (ii) the date that is six months after the date of issuance
of the Notes,  in either  case,  whether or not the Company is then  required to
file reports with the Commission, the Company shall file with the Commission all
such  reports  and other  information  as it would be  required to file with the
Commission by Sections 13(a) or 15(d) under the Securities  Exchange Act of 1934
if it were subject thereto. The Company shall supply the Trustee and each Holder
or shall supply to the Trustee for forwarding to each such Holder,  without cost
to such Holder,  copies of such reports and other information.  In addition,  at
all times prior to the earlier of the date of the Registration and the date that
is six months after the date of issuance of the Notes, the Company shall, at its
cost,  deliver  to  each  Holder  of the  Notes  quarterly  and  annual  reports
substantially  equivalent  to those which would be required by the Exchange Act.
In  addition,  at all times prior to the  Registration,  upon the request of any
Holder or any  prospective  purchaser of the Notes  designated by a Holder,  the
Company  shall  supply  to  such  Holder  or  such  prospective   purchaser  the
information required under Rule 144A under the Securities Act.

         Delivery of such reports,  information  and documents to the Trustee is
for  informational  purposes  only and the  Trustee's  receipt of such shall not
constitute   constructive  notice  of  any  information   contained  therein  or
determinable  from  information  contained  therein,   including  the  Company's
compliance  with any of its  covenants  hereunder  (as to which the  Trustee  is
entitled to rely exclusively on Officers' Certificates).

         SECTION  4.19.  Waiver of Stay,  Extension  or Usury Laws.  The Company
covenants  (to the extent  that it may  lawfully  do so) that it will not at any
time  insist  upon,  or plead,  or in any  manner  whatsoever  claim or take the
benefit or advantage of, any stay or extension law or any usury law or other law
that would prohibit or forgive the Company from paying all or any portion of the
principal of, premium, if any, or interest on the Notes as contemplated  herein,
wherever enacted,  now or at any time hereafter in force, or that may affect the
covenants or the performance of this  Indenture;  and (to the extent that it may
lawfully do so) the Company hereby  expressly waives all benefit or advantage of
any such  law and  covenants  that it will  not  hinder,  delay  or  impede  the
execution of any power herein granted to the Trustee, but will suffer and permit
the execution of every such power as though no such law had been enacted.

otherwise  dispose of all or substantially all of its property and assets (as an
entirety or  substantially an entirety in one transaction or a series of related

    Consolidated Net Worth of the Company immediately prior to such transaction;

         (iv)   immediately  after  giving effect  to such  transaction on a pro
    forma basis, the Company, or any  Person  becoming the  successor obligor of
    the Notes,  could  Incur at least  $1.00 of  Indebtedness  under  the  first
    paragraph of Section  4.03 hereof;  provided that this clause (iv) shall not
    apply to (1) a  consolidation, merger or sale of all (but not less than all)
    of the assets of the Company if all Liens and Indebtedness of the Company or
    any Person becoming the successor  obligor on the Notes, as the case may be,
    and  its  Restricted   Subsidiaries  outstanding   immediately  after   such
    transaction  would,  if  Incurred  a  such  time,  have been permitted to be
    Incurred  (and  all such  Liens  and  Indebtedness,  other  than  Liens  and
    Indebtedness  of the Company  and its  Restricted  Subsidiaries  outstanding
    immediately prior to the transaction, shall be deemed to have been Incurred)

    clauses (iii) and (iv) of this Section 5.01) and Opinion of Counsel, in each

    supplemental  indenture complies with this provision and that all conditions
    precedent  provided  for  herein  relating  to such  transaction  have  been
    complied with;

provided, however, that clauses (iii) and (iv) of this Section 5.01 do not apply
if,  in  the  good  faith  determination  of  the  Board  of  Directors,   whose
determination shall be evidenced by a Board Resolution, the principal purpose of
such  transaction is to change the state of  incorporation  of the Company;  and
provided further that any such transaction shall not have as one of its purposes
the evasion of the foregoing limitations.

                                   ARTICLE SIX
                              DEFAULT AND REMEDIES

         SECTION 6.01. Events of Default. An "Event of Default" shall occur with
respect to the Notes if:

         (a) the Company defaults in the payment of principal of (or premium, if
    any, on) any Note when the same  becomes due and payable at  maturity,  upon
    acceleration, redemption or otherwise;

         (b) the  Company  defaults  in the payment of interest on any Note when
    the same becomes due and payable, and such default continues for a period of
    30 days;  provided  that a failure to make any of the first three  scheduled
    interest  payments on the Notes in a timely manner will  constitute an Event
    of Default with no grace or cure period;

         (c) the Company defaults in the performance or breach of the provisions
    of Article Five hereof or fails to make or  consummate  an Offer to Purchase
    in accordance with Section 4.11 or Section 4.12 hereof;

    6.01) and such default or breach  continues  for a period of 30  consecutive
    days after  written  notice by the  Trustee or the Holders of 25% or more in
    aggregate principal amount of the Notes;

         (e) there occurs with respect to any issue or issues of Indebtedness of
    the Company or any Significant  Subsidiary  having an outstanding  principal
    amount of $10  million or more in the  aggregate  for all such issues of all
    such Persons,  whether such  Indebtedness  now exists or shall  hereafter be
    created,  (I) an event of default  that has  caused  the  holder  thereof to
    declare such Indebtedness to be due and payable prior to its Stated Maturity
    and such  Indebtedness has not been discharged in full or such  acceleration
    has not been  rescinded  or  annulled  within  30 days of such  acceleration
    and/or (II) the  failure to make a  principal  payment at the final (but not
    any interim) fixed  maturity and such defaulted  payment shall not have been
    made, waived or extended within 30 days of such payment default;

         (f) any final  judgment  or order (not  covered by  insurance)  for the
    payment  of money in excess of $10  million  in the  aggregate  for all such
    final   judgments  or  orders   against  all  such  Persons   (treating  any
    deductibles,  self-insurance  or  retention  as not  so  covered)  shall  be
    rendered against the Company or any Significant  Subsidiary and shall not be
    paid or  discharged,  and there shall be any period of 60  consecutive  days
    following  entry of the final  judgment or order that  causes the  aggregate
    amount for all such final  judgments or orders  outstanding  and not paid or

<PAGE>

    discharged  against all such  Persons to exceed $10 million  during  which a
    stay of enforcement of such final judgment or order,  by reason of a pending
    appeal or otherwise, shall not be in effect;

         (g) a court  having  jurisdiction  in the  premises  enters a decree or

    of the property and assets of the Company or any  Significant  Subsidiary or
    (C) the  winding up or  liquidation  of the  affairs  of the  Company or any
    Significant  Subsidiary and, in each case, such decree or order shall remain

         (h) the Company or any Significant Subsidiary (A) commences a voluntary
    case under any applicable bankruptcy, insolvency or other similar law now or

    involuntary  case under any such law, (B) consents to the  appointment of or
    taking possession by a receiver,  liquidator,  assignee, custodian, trustee,
    sequestrator  or  similar   official  of  the  Company  or  any  Significant
    Subsidiary or for all or substantially all of the property and assets of the
    Company or any Significant  Subsidiary or (C) effects 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 (g) or (h) 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  amount of,  premium,  if any, and
accrued  interest  on the  Notes  to be  immediately  due  and  payable.  Upon a
declaration of  acceleration,  such principal  amount of,  premium,  if any, and
accrued  interest  shall  be  immediately  due and  payable.  In the  event of a
declaration of acceleration  because an Event of Default set forth in clause (e)
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 (e) shall be remedied or cured by the
Company or the relevant  Significant  Subsidiary or waived by the holders of the
relevant  Indebtedness within 60 days after the declaration of acceleration with
respect  thereto.  If an Event of  Default  specified  in  clause  (g) or (h) of
Section  6.01 occurs  with  respect to the  Company,  the  principal  amount of,
premium,  if any, and accrued 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.

         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 (i)  all  existing  Events  of  Default,  other  than  the
nonpayment of the principal of, premium,  if any, and interest on the Notes that
have become due solely by such declaration of  acceleration,  have been cured or

<PAGE>

waived and (ii) 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 pursue any available remedy by proceeding at law or
in equity to collect the payment of principal of,  premium,  if any, 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 Section 9.02, at any
time after such a 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 aggregate 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  (except a
Default in the payment of principal of premium,  if any, or interest on any Note
as  specified  in clause (a) or (b) of Section 6.01 (but not as a result of such
acceleration)  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) if (i) all existing Events of Default, other than the
nonpayment  of the  principal  amount of,  premium,  if any, and interest on the
Notes that have become due solely by such declaration of acceleration, have been
cured or waived and (ii) the rescission  would not conflict with any judgment or
decree of a court of competent jurisdiction.  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.  However, the
Trustee  may  refuse to follow any  direction  that  conflicts  with law or this
Indenture,  that may  involve the  Trustee in  personal  liability,  or that the
Trustee  determines  in good  faith may be unduly  prejudicial  to the rights of
Holders of the Notes,  not joining in the giving of such  direction and may take
any  other  action  it  deems  proper  that is not  inconsistent  with  any such
direction received from Holders of the Notes.

         SECTION 6.06.  Limitation on Suits.  A Holder may not pursue any remedy
with respect to this Indenture or the Notes unless:

         (i) the Holder gives the Trustee  written notice of a continuing  Event
    of Default;

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

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


<PAGE>

         (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 6.06,
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 6.07. 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 principal of,  premium,  if any, or interest on such Holder's Note on
or after the respective  due dates  expressed on such Note, or to bring suit for
the enforcement of any such payment on or after such respective dates, shall not
be impaired or affected without the consent of such Holder.

         SECTION  6.08.  Collection  Suit by Trustee.  If an Event of Default in
payment of  principal,  premium or  interest  specified  in clause (a) or (b) of
Section 6.01 of this Indenture 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, premium, if
any, and accrued interest  remaining  unpaid,  together with interest on overdue
principal,  premium, if any, and, to the extent that payment of such interest is
lawful,  interest on overdue installments of interest,  in each case at the rate
specified in the Notes,  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, and
any other amounts due the Trustee under Section 7.07 hereof.

         SECTION  6.09.  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 the  Trustee  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 agent 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

<PAGE>

composition  affecting  the Notes or the  rights of any  Holder  thereof,  or to
authorize  the Trustee to vote in respect of the claim of any Holder in any such
proceeding.

         SECTION 6.10. Priorities. If the Trustee collects any money pursuant to
this Article Six, it shall pay out the money in the following order:

         First: to the Trustee for all amounts due under Section 7.07;

         Second:  to Holders for amounts then due and unpaid for  principal  of,
    premium,  if any,  and  interest on the Notes in respect of which or for the
    benefit of which such money has been collected,  ratably, without preference
    or  priority of any kind,  according  to the amounts due and payable on such
    Notes for principal, premium, if any, and interest, respectively; and

         Third: to the Company as its interests may appear.

         The Trustee, upon prior written notice to the Company, may fix a record
date and payment date for any payment to Holders pursuant to this Section 6.10.

         SECTION 6.11. Undertaking for Costs. In any suit for the enforcement of
any right or remedy under this  Indenture or in any suit against the Trustee for
any action  taken or omitted by it as  Trustee,  a court may  require  any party
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 and
expenses, against any party litigant in the suit having due regard to the merits
and good  faith of the  claims  or  defenses  made by the party  litigant.  This
Section  6.11  does  not  apply  to a suit by the  Trustee,  a suit by a  Holder
pursuant to Section  6.07 of this  Indenture,  or a suit by Holders of more than
10% in principal amount of the outstanding Notes.

         SECTION 6.12. 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, the Trustee and the Holders shall continue as though no such proceeding
had been instituted.

         SECTION  6.13.  Rights and  Remedies  Cumulative.  Except as  otherwise
provided with respect to the  replacement  or payment of  mutilated,  destroyed,
lost or  wrongfully  taken  Notes in  Section  2.09,  no right or remedy  herein
conferred  upon or  reserved  to the Trustee or to the Holders is intended to be
exclusive of any other right or remedy, and every right and remedy shall, to the
extent  permitted by law, be cumulative and in addition to every other right and
remedy  given  hereunder  or now or  hereafter  existing  at law or in equity or
otherwise.  The  assertion or employment  of any right or remedy  hereunder,  or
otherwise, shall not prevent the concurrent assertion or employment of any other
appropriate right or remedy.

         SECTION 6.14. Delay or Omission Not Waiver. No delay or omission of the
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

<PAGE>

such Event of Default or an acquiescence  therein.  Every right and remedy given
by this  Article Six or by law to the Trustee or to the Holders may be exercised
from time to time, and as often as may be deemed expedient, by the Trustee or by
the Holders, as the case may be.


                                  ARTICLE SEVEN
                                     TRUSTEE

         SECTION 7.01. General.  The duties and  responsibilities of the Trustee
shall be as provided  by the TIA and as set forth  herein.  Notwithstanding  the
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 therein 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
Article Seven.

         SECTION 7.02. Certain Rights of Trustee. Subject to TIA Sections 315(a)
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  or other paper or
    document  (whether in its original or facsimile  form)  believed by it to be
    genuine  and to have been  signed or  presented  by the proper  person.  The
    Trustee need not  investigate  any fact or matter stated in the document and
    may in good faith  conclusively  rely as to the truth of the  statements and
    the correctness of the opinions therein;

         (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  10.04 of this  Indenture.  The Trustee  shall not be liable for any
    action  it  takes  or  omits  to take  in good  faith  in  reliance  on such
    certificate,  opinion and/or an  accountants'  certificate if required under
    the TIA;

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

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

         (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 or for any  action it takes or omits to take in  accordance  with the

<PAGE>

    direction  of  the  Holders  of  a  majority  in  principal  amount  of  the
    outstanding  Notes relating to the time,  method and place of conducting any
    proceeding for any remedy available to the Trustee,  or exercising any trust
    or power conferred upon the Trustee, under this Indenture; 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  to take any action  hereunder,  the Trustee  (unless
    other evidence be herein specifically prescribed) may, in the absence of bad
    faith on its part, rely upon an Officers' Certificate;

         (vii) the Trustee shall not be bound to make any investigation into the
    facts  or  matters  stated  in  any  resolution,   certificate,   statement,
    instrument,  opinion,  report, notice, request,  direction,  consent, order,
    bond,  debenture,  note,  other evidence of  indebtedness  or other paper or
    document, but the Trustee, in its discretion,  may make such further inquiry
    or  investigation  into such facts or matters as it may see fit, and, if the
    Trustee shall  determine to make such further inquiry or  investigation,  it
    shall be  entitled  at the sole cost of the  Company to  examine  the books,
    records and premises of the Company  personally  or by agent or attorney and
    shall incur no  liability or  additional  liability of any kind by reason of
    such inquiry or investigation;

         (viii) the Trustee  shall not be charged with  knowledge of any Default
    or Event of Default,  the identity of any  Restricted  Subsidiary  or of the
    existence  of any  Change of  Control  or Asset  Sale  unless  either  (i) a
    Responsible Officer shall have actual knowledge thereof, or (ii) the Trustee
    shall have received written notice thereof from the Company or any Holder of
    the Notes; and

         (ix) 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 to be taken by it hereunder in good faith and in reliance thereon.

         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  (a)  makes  no
representation  as to the  validity or adequacy of this  Indenture or the Notes,
(b)  shall  not be  accountable  for the  Company's  use or  application  of the
proceeds of the Notes and (c) 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 90 days after it occurs, unless such Default or Event of
Default has been cured; provided, however, that, except in the case of a default

<PAGE>

in the payment of the  principal of,  premium,  if any, or interest on any Note,
the Trustee shall be protected in withholding  such notice if and as 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.  If an Event of
Default has occurred and is continuing, the Trustee shall use the same degree of
care and skill in its  exercise  of the rights and powers  invested  in it under
this Indenture as a prudent person would exercise under the circumstances in the
conduct of such person's own affairs.

         SECTION 7.06. Reports by Trustee to Holders.  Within 60 days after each
May 15,  beginning  with May 15, 2000,  the Trustee shall mail to each Holder as
provided in TIA Section  313(c) a brief  report that  complies  with TIA Section
313(a) dated as of such May 15, if required by TIA Section 313(a).

         SECTION 7.07. Compensation and Indemnity.  The Company shall pay to the
Trustee such  compensation  as shall be agreed upon from time to time in writing
for its services.  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 out-of-pocket expenses and
advances  incurred  or made by the  Trustee.  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, claim, damage or liability
or  expense  (including  taxes  other  than  taxes  based upon the income of the
Trustee)  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 asserted against the
Trustee for which it may seek indemnity.  The Company shall defend the claim and
the Trustee shall provide reasonable cooperation at the Company's expense in the
defense.  The Trustee may have separate counsel of its selection and the Company
shall pay the reasonable fees and expenses of such counsel;  provided,  that the
Company  will not be  required  to pay such fees and  expenses if it assumes the
Trustee's  defense and there is no conflict of interest  between the Company and
the Trustee in connection  with such  defense.  The Company need not pay for any
settlement made without its written consent.

         To secure the Company's  payment  obligations in this Section 7.07, the
Trustee shall have a lien prior to the Noteholders on all money or property held
or  collected  by the  Trustee,  in its  capacity  as Trustee,  except  money or
property  held in trust to pay principal  of,  premium,  if any, and interest on
particular Notes.

         If the Trustee incurs expenses or renders services after the occurrence
of an Event of  Default  specified  in clause (h) or (i) 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.


<PAGE>

         The rights, privileges,  protections and benefits given to the Trustee,
including,  without limitation,  its rights to be indemnified,  are extended to,
and shall be enforceable by, the Trustee in each of its capacities hereunder.

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

         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 its  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 remove
the Trustee by so  notifying  the Trustee in writing and may appoint a successor
Trustee with the consent of the Company.  The Company may at any time remove the
Trustee,  by  Company  Order  given at  least  30 days  prior to the date of the
proposed  removal;  provided  that, at such date, no Event of Default shall have
occurred and be continuing.

         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 petition at the
expense of the Company 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 of this  Indenture,  (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.

         If the  Trustee  is no  longer  eligible  under  Section  7.10  of this
Indenture,  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 successor Trustee.

         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.

         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

<PAGE>

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.

         SECTION 7.10.  Eligibility.  This Indenture shall always have a Trustee
who satisfies the  requirements  of TIA Sections  310(a)(1) and  310(a)(5).  The
Trustee shall have a combined capital and surplus of at least $50,000,000 as set
forth in its most recent published annual report of condition.

         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 in writing.  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.

         SECTION 7.12. Withholding Taxes. The Trustee, as agent for the Company,
shall exclude and withhold from each payment of principal and interest and other
amounts  due  hereunder  or  under  the  Notes  any  and all  withholding  taxes
applicable  thereto  as  required  by law.  The  Trustee  agrees  to act as such
withholding agent and, in connection  therewith,  whenever any present or future
taxes or similar charges are required to be withheld with respect to any amounts
payable in respect of the Notes,  to  withhold  such  amounts and timely pay the
same to the appropriate authority in the name of and on behalf of the Holders of
the Notes, that it will file any necessary withholding tax returns or statements
when due, and that, as promptly as possible after the payment  thereof,  it will
deliver  to each  Holder  of a Note  appropriate  documentation  evidencing  the
payment  thereof,  together with such  additional  documentary  evidence as such
Holders may reasonably request from time to time.


                                  ARTICLE EIGHT
                             DISCHARGE OF INDENTURE

         SECTION  8.01.  Termination  of the  Company's  Obligations.  Except as
otherwise  provided  in  this  Section  8.01,  the  Company  may  terminate  its
obligations under the Notes and this Indenture if:

         (i) all  Notes  previously  authenticated  and  delivered  (other  than
    destroyed,  lost or stolen  Notes that have been  replaced or Notes that are
    paid  pursuant to Section  4.01 hereof 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  hereof)  have been  delivered to the
    Trustee for  cancellation  and the  Company has paid all sums  payable by it
    hereunder; or

         (ii) (A) all of the Notes mature  within one year or all of them are to
    be called for redemption within one year under arrangements  satisfactory to
    the Trustee for giving the notice of redemption, (B) the Company 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 to pay principal,
    premium,  if, any, and interest on the Notes to maturity or  redemption,  as
    the case may be, and to pay all other sums payable by it  hereunder,  (C) no

<PAGE>

    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, (E) if at such time the Notes are listed on a
    national securities exchange,  the Notes will not be delisted as a result of
    such  deposit,  defeasance or discharge and (F) 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 hereof 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, 2.14, 4.01, 4.02, 7.07, 7.08, 8.04, 8.05 and 8.06 of this Indenture
shall survive until the Notes are no longer  outstanding.  Thereafter,  only the
Company's  obligations in Sections 7.07,  8.05 and 8.06 of this Indenture  shall
survive.  After any such  irrevocable  deposit,  the Trustee upon request  shall
acknowledge in writing the discharge of the Company's  obligations,  as the case
may be,  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 123rd day after the deposit  referred to below,  and

<PAGE>

the provisions of this Indenture will no longer be in effect with respect to the
Notes if:

         (A) the Company has deposited with the Trustee,  in trust, money and/or
    U.S.  Government  Obligations  that  through  the  payment of  interest  and
    principal  in respect  thereof in  accordance  with their terms will provide
    money in an amount sufficient to pay the principal of, premium,  if any, and
    accrued  interest on the Notes on the Stated  Maturity  of such  payments in
    accordance with the terms of this Indenture and the Notes;

         (B) the Company has  delivered to the Trustee (i) either (1) 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  deposit,  defeasance  and  discharge  had not
    occurred,  which Opinion of Counsel must 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 (2) a ruling
    directed to the Trustee  received from the Internal  Revenue  Service to the
    same effect as the aforementioned  Opinion of Counsel and (ii) an Opinion of
    Counsel to the effect  that the  creation of the  defeasance  trust does not
    violate the Investment Company Act of 1940 and after the passage of 123 days
    following  the deposit,  the trust fund will not be subject to the effect of
    Section 547 of the United  States  Bankruptcy  Code or Section 15 of the New
    York Debtor and Creditor Law;

         (C)  immediately  after  giving  effect to such  deposit on a pro forma
    basis,  no Event of  Default,  or event  that  after the giving of notice or
    lapse of time or both would become an Event of Default,  shall have occurred
    and be continuing on the date of such deposit or during the period ending on
    the 123rd day after the date of such  deposit,  and such  deposit  shall not
    result in a breach or violation of, or constitute a default under, any other
    agreement or instrument to which the Company or any of its Subsidiaries is a
    party or by which the Company or any of its Subsidiaries is bound; and

         (D) if at such  time the  Notes are  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.

         Notwithstanding  the foregoing,  prior to the end of the 123-day period
referred  to in clause  (B)(ii)  of this  Section  8.02,  none of the  Company's
obligations  under this Indenture shall be discharged.  Subsequent to the end of
such 123-day period with respect to this Section 8.02, the Company's obligations
in Sections 2.02,  2.03,  2.04,  2.05, 2.06, 2.07, 2.08, 2.09, 2.14, 4.01, 4.02,
4.17,  7.07,  7.08,  8.05 and 8.06 shall  survive  until the Notes are no longer
outstanding.  Thereafter,  only the Company's obligations in Sections 7.07, 8.05
and 8.06 shall survive.  If and when a ruling from the Internal  Revenue Service
or an Opinion of Counsel  referred to in clause  (B)(i) of this Section 8.02 may
be  provided  specifically  without  regard to, and not in  reliance  upon,  the
continuance of the Company's  obligations under Section 4.01, then the Company's
obligations  under such Section 4.01 shall cease upon delivery to the Trustee of

<PAGE>

such  ruling or Opinion  of Counsel  and  compliance  with the other  conditions
precedent  provided for herein  relating to the defeasance  contemplated by this
Section 8.02.

         After the 123 day period  referred to in clause (B)(ii) of this Section
8.02, the Trustee upon Company Order 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.

         SECTION 8.03.  Defeasance of Certain Obligations.  The Company may omit
to comply with any term,  provision or condition  set forth in clauses (iii) and
(iv) of Section 5.01 and  Sections  4.03  through  4.11 of this  Indenture,  and
clause (c) of  Section  6.01 with  respect to clauses  (iii) and (iv) of Section
5.01 of this  Indenture  and clause (d) of Section 6.01 with respect to Sections
4.01, 4.02 and 4.12 through 4.19 hereof, and clauses (e) and (f) of Section 6.01
hereof shall be deemed not to be Events of Default, upon:

         (a) the  deposit,  in  trust,  with the  Trustee  (or  another  trustee
    satisfying  the  requirements  of Section  7.10 hereof) of money and/or U.S.
    Government  Obligations that,  through the payment of interest and principal
    in respect thereof in accordance with their terms,  will provide money in an
    amount  sufficient  to pay the principal  of,  premium,  if any, and accrued
    interest on the Notes on the Stated  Maturity of such payments in accordance
    with the terms of this Indenture and the Notes;

         (b) the satisfaction of the provisions  described in clauses B(ii), (C)
    and (D) of Section 8.02 hereof;

         (c)  delivery by the Company to the Trustee of 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 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; and

         (d) the  Company  shall have  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,  premium,  if any, 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 any excess  money,  as  determined  by a nationally  recognized  firm of
independent  public  accountants  expressed in a written  certification  thereof
delivered to the Trustee,  and 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,  premium,  if any, or interest that remains  unclaimed
for two years;  provided  that the Trustee or such  Paying  Agent  before  being
required  to make any payment  may cause to be  published  at the expense of the

<PAGE>

Company  once in 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 Note Register)  notice that such money remains  unclaimed  provided
that the Trustee or such Paying Agent before being  required to make any payment
may give notice in  accordance  with Section  11.02(b)  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 the 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,  premium,  if any, 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.

         SECTION 8.07.  Defeasance  and Certain Other Events of Default.  In the
event that the Company  exercises  its option to omit  compliance  with  certain
covenants and provisions of this Indenture with respect to the Notes pursuant to
Section  8.03 and  such  Notes  are  declared  due and  payable  because  of the
occurrence of an Event of Default that remains  applicable,  the amount of money
and/or  U.S.  Government  Obligations  on  deposit  with  the  Trustee  will  be
sufficient  to pay  amounts  due on  such  Notes  at the  time of  their  Stated
Maturity.  If, in the event the Company  exercises its option to omit compliance
with certain  covenants  and  provisions of this  Indenture  with respect to the
Notes  pursuant  to Section  8.03 and such Notes are  declared  due and  payable
because of the  occurrence of an Event of Default that remains  applicable,  the
amount of money and/or U.S.  Government  Obligations on deposit with the Trustee
is insufficient to pay amounts due on the Notes at the time of the  acceleration
resulting from such Events of Default pursuant to Section 6.02, the Company will
remain liable for such payments.


                                  ARTICLE NINE
                       AMENDMENTS, SUPPLEMENTS AND WAIVERS

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


<PAGE>

         (a) to cure any ambiguity,  defect or  inconsistency in this Indenture;
    provided  that,  in the good faith  opinion of the Board of Directors of the
    Company evidenced by a Board  Resolution,  such amendments or supplements do
    not adversely affect the interests of the Holders in any material respect;

         (b) to comply with Article Five;

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

         (d) to evidence and provide for the acceptance of appointment hereunder
    by a successor Trustee; or

         (e) to make any change that,  in the good faith opinion of the Board of
    Directors  of  the  Company  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  6.07 and
without prior notice to the Holders,  the Company,  when authorized by its Board
of Directors  (as  evidenced by a Board  Resolution),  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 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  thereby,  an amendment or waiver,  including a
waiver pursuant to Section 6.04 hereof, may not:

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

         (b) reduce the principal amount of, or premium, if any, or interest on,
    any Note;

         (c)  change  the place or  currency  of  payment  of  principal  of, or
    premium, if any, or interest on, any Note;

         (d)  impair  the right to  institute  suit for the  enforcement  of any
    payment on or after the Stated Maturity (or, in the case of a redemption, on
    or after the Redemption Date) of any Note;

         (e)  reduce the  above-stated  percentage  of  outstanding  Notes,  the
    consent of whose Holders is necessary to modify or amend this Indenture;

         (f) waive a default in the payment of principal of, premium, if any, or
    interest on the Notes; or

         (g) reduce the percentage or aggregate  principal amount of outstanding
    Notes the consent of whose  Holders is  necessary  for waiver of  compliance
    with certain provisions of this Indenture or for waiver of certain defaults.

         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.


<PAGE>

         After an  amendment,  supplement  or waiver  under  this  Section  9.02
becomes  effective,  the Trustee  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.

         SECTION 9.03.  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.

         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 any of  clauses  (i)
through  (vii) of Section  9.02.  In case of an  amendment or waiver of the type
described in clauses (i) through (vii) 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.  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  it to the  Trustee.  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  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.

         SECTION  9.05.  Trustee to Sign  Amendments,  Etc. The Trustee shall be
entitled to receive,  and shall be fully  protected in relying upon, in addition
to the documents  required by Section 11.03,  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.  Subject to the
preceding sentence, the Trustee shall sign such amendment,  supplement or waiver
if the same does not  adversely  affect the rights 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.


<PAGE>

         SECTION 9.06.  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.


                                   ARTICLE TEN
                                    SECURITY

         SECTION  10.01.  Security.  (a) On the  issue  date of the  Notes,  the
Company shall (i) enter into the Pledge  Agreement and comply with the terms and
provisions thereof and (ii) purchase the Pledged Securities to be pledged to the
Trustee for the benefit of the Holders in such amount as will be sufficient upon
receipt  of  scheduled  interest  and/or  principal  payments  of  such  Pledged
Securities to provide for payment in full of the first three scheduled  interest
payments  due on the  Notes.  The  Pledged  Securities  shall be  pledged by the
Company to the  Trustee  for the benefit of the Holders and shall be held by the
Trustee  in the  Pledge  Account  pending  disposition  pursuant  to the  Pledge
Agreement.

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

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


<PAGE>

         (d) The Company shall cause TIA Section 314(b), relating to opinions of
counsel regarding the Lien under the Pledge Agreement,  to be complied with. The
Trustee  may  accept,  to the  extent  permitted  by  Sections  4.18 and 7.06 as
conclusive evidence of compliance with the foregoing provisions, the appropriate
statements contained in such instruments.

         (e) The Trustee may, in its sole  discretion and without the consent of
the Holders, on behalf of the Holders, take all reasonable actions in accordance
with the Pledge  Agreement  necessary or appropriate in order to (i) enforce any
of the terms of the Pledge  Agreement  and (ii)  collect and receive any and all
amounts  payable in respect of the  obligations of the Company  thereunder.  The
Trustee shall have power to institute and to maintain such suits and proceedings
as the  Trustee  may  reasonably  deem  expedient  to  preserve  or protect  its
interests and the interests of the Holders in the Pledged Securities  (including
power to institute and maintain suits or proceedings to restrain the enforcement
of or compliance with any legislative or other governmental  enactment,  rule or
order that may be  unconstitutional  or otherwise invalid if the enforcement of,
or  compliance  with,  such  enactment,  rule or order would impair the security
interest  hereunder or be  prejudicial to the interests of the Holders or of the
Trustee).


                                 ARTICLE ELEVEN
                                  MISCELLANEOUS

extent applicable, be governed by such provisions.

              Attention: Anthony Harvin

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

         All notices and communications (other than those sent to Holders) shall
be deemed to have been duly given:  at the time delivered by hand, if personally
delivered;  five  Business  Days  after  being  deposited  in the mail,  postage
prepaid,  if mailed;  when receipt  acknowledged,  if  telecopied;  and the next
Business Day after  timely  delivery to the  courier,  if sent by overnight  air

         (b) Any notice or  communication  mailed to a Holder shall be mailed to
him at his  address as it appears on the Note  Register  by first class mail and
shall be  sufficiently  given to him if so mailed  within  the time  prescribed.
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 or any defect in
it 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.

         (c) 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.

         SECTION 11.03. Certificate and Opinion as to Conditions Precedent. Upon
any  request or  application  by the  Company to the  Trustee to take any action
under this Indenture, the Company shall furnish to the Trustee:


<PAGE>

         (a) an  Officers'  Certificate  stating  that,  in the  opinion  of the
    signers,  all conditions  precedent,  if any, provided for in this Indenture
    relating to the proposed action have been complied with; and

         (b) an Opinion of Counsel stating that, in the opinion of such Counsel,
    all such conditions precedent have been complied with.

         SECTION 11.04.  Statements  Required in  Certificate  or Opinion.  Each

provided for in this Indenture shall include:

         (a) a statement  that each person  signing such  certificate or opinion
    has read such  covenant or condition  and the  definitions  herein  relating
    thereto;

         (b) a brief  statement as to the nature and scope of the examination or
    investigation  upon  which  the  statement  or  opinion  contained  in  such
    certificate or opinion is based;

         (c) a statement  that, in the opinion of each such person,  he has made
    such  examination or  investigation as is necessary to enable him to express
    an informed opinion as to whether or not such covenant or condition has been
    complied with; and

         (d) a  statement  as to  whether  or not,  in the  opinion of each such
    person,  such  condition  or  covenant  has been  complied  with;  provided,
    however,  that,  with respect to matters of fact,  an Opinion of Counsel may
    rely on an Officers' Certificate or certificates of public officials.

         SECTION 11.05. Rules by Trustee, Paying Agent or Registrar. The Trustee
may make reasonable  rules for action by or at a meeting of Holders.  The Paying
Agent or Registrar may make reasonable rules for its functions.

         SECTION  11.06.  Payment Date Other Than a Business Day. If an Interest
Payment Date, Redemption Date, Payment Date, Stated Maturity or date of maturity
of any Note shall not be a Business Day, then payment of principal of,  premium,
if any, or  interest on such Note,  as the case may be, need not be made on such
date,  but may be made on the next  succeeding  Business Day with the same force
and effect as if made on the Interest Payment Date,  Payment Date, or Redemption
Date, or at the Stated Maturity or date of maturity of such Note;  provided that
no interest  shall  accrue for the period from and after such  Interest  Payment
Date, Payment Date, Redemption Date, Stated Maturity or date of maturity, as the
case may be.

         SECTION 11.07.  Governing Law;  Submission to  Jurisdiction;  Agent for
Service. This Indenture and the Notes shall be governed by the laws of the State
of New York. The Company hereby appoints CT Corporation  System as its agent for
service  of  process  in any suit,  action or  proceeding  with  respect to this
Indenture or the Notes and for actions  brought under the U.S.  federal or state
securities laws brought in any federal or state court located in the City of New
York and the Company agrees to submit to the jurisdiction of any such court.

         SECTION 11.08.  No Adverse  Interpretation  of Other  Agreements.  This
Indenture may not be used to interpret another indenture, loan or debt agreement
of the Company or any  Subsidiary of the Company.  Any such  indenture,  loan or
debt agreement may not be used to interpret this Indenture.

any claim based thereon or otherwise in respect  thereof,  and no recourse under
or upon any obligation,  covenant or agreement of the Company  contained in this
Indenture,  or in  any  of  the  Notes,  or  because  of  the  creation  of  any
Indebtedness  represented  thereby,  shall be had  against any  incorporator  or
against any past, present or future partner,  stockholder,  other equity holder,
officer, director, employee or controlling person, as such, of the Company or of
any successor  Person,  either  directly or through the Company or any successor
Person, whether by virtue of any constitution, statute or rule of law, or by the
enforcement  of any  assessment  or penalty  or  otherwise;  it being  expressly
understood that all such liability is hereby  expressly waived and released as a
condition of, and as a  consideration  for, the execution of this  Indenture and
the issue of the Notes.

         SECTION  11.10.  Successors.  All  agreements  of the  Company  in this
Indenture and the Notes shall bind its successors. All agreements of the Trustee
in this Indenture shall bind its successors.

         SECTION 11.11. Duplicate Originals.  The parties may sign any number of
copies of this Indenture. Each signed copy shall be an original, but all of them
together represent the same agreement.

         SECTION 11.12. Separability. In case any provision in this Indenture or
in the Notes shall be invalid, illegal or unenforceable,  the validity, legality
and enforceability of the remaining  provisions shall not in any way be affected
or impaired thereby.

         SECTION 11.13. Table of Contents, Headings, Etc. The Table of Contents,
Cross-Reference  Table  and  headings  of the  Articles  and  Sections  of  this
Indenture have been inserted for  convenience  of reference  only, are not to be
considered a part hereof and shall in no way modify or restrict any of the terms
and provisions hereof.

         SECTION 11.14. Counterparts. This Indenture may be signed in any number
of counterparts,  each of which shall be an original, with the same effect as if
the signatures thereto and hereto were upon the same instrument.

                       11.50% Senior Dollar Note due 2009



1.   Principal and Interest.

         The Company will pay the principal of this Note on March 15, 2009.

         The Company  promises to pay interest on the  principal  amount of this
Note on each Interest  Payment  Date, as set forth below,  at the rate per annum
shown above.

         Interest will be payable semiannually in cash (to the holders of record
of the Notes at the close of business on the March 1 or September 1  immediately
preceding the Interest Payment Date) on each Interest  Payment Date,  commencing
March 15,  2000.  Interest  will be computed  on the basis of a 360-day  year of
twelve 30-day months.

         If an  exchange  offer  registered  under  the  Securities  Act  is not
consummated,  and a shelf  registration  statement under the Securities Act with
respect to resales of the Notes is not declared effective by the Commission,  on
or before  the date  that is six  months  after  the issue  date of this Note in
accordance  with the terms of the  Registration  Rights  Agreement,  dated as of
December 8, 1999,  between the  Company and Morgan  Stanley & Co.  Incorporated,
annual  interest  (in  addition  to  interest  otherwise  due on the Notes) will
accrue, at an annual rate of .5% per annum of the principal  amount,  payable in
cash  semiannually,  in  arrears  on March  15 and  September  15 of each  year,
commencing  September 15, 2000 until the  consummation of a registered  exchange
offer or the  effectiveness  of a  shelf-registration  statement with respect to
resale of this Note. The Holder of this Note is entitled to the benefits of such
Registration Rights Agreement.

         The  Holder  of this  Note is  entitled  to the  benefits  of a  Pledge
Agreement, dated as of December 8, 1999, between the Company and The Bank of New
York,  as trustee (the  "Trustee"),  pursuant to which the Company has placed in
the Pledge Account cash or Government  Securities  sufficient to provide for the
payment of the first three interest payments on this Note.

         The Company  shall pay interest on overdue  principal  and premium,  if
any, and interest on overdue installments of interest,  to the extent lawful, at
a rate per annum that is 11.50% per annum.

2.   Method of Payment.

         The Company will pay principal as provided  above and interest  (except
defaulted  interest) on the principal  amount of the Notes as provided  above on
each March 15 and  September 15 to the Persons who are Holders (as  reflected in
the Note  Register  at the close of business  on such March 1 and  September  1,
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 not make payment to the Holder unless this Note is surrendered to a
Paying Agent.


<PAGE>

         The Company will pay principal, premium, if any, and as provided above,
interest  in the  currency  of the United  States that at the time of payment is
legal tender for the payment of public and private debts.  However,  the Company
may pay  principal,  premium,  if any, and interest by its check payable in such
currency.  It may mail an interest  check to a Holder's  registered  address (as
reflected  in the Note  Register).  If a  payment  date is a date  other  than a
Business  Day at a place of  payment,  payment  may be made at that place on the
next  succeeding day that is a Business Day and no interest shall accrue for the
intervening period.

3.   Paying Agent and Registrar.

         Initially,  the Trustee  will act as Paying  Agent and  Registrar.  The
Company may change any Paying 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.

4.   Indenture; Issuance of Additional Notes.

         This  Note is one of a duly  authorized  issue of Notes of the  Company
designated  its 11.50%  Senior  Dollar  Notes due 2009,  issued and to be issued

principal amount of the Notes with the net proceeds of one or more Public Equity

in original denominations larger than $1,000 of principal amount may be redeemed

portions of Notes  called for  redemption,  unless the  Company  defaults in the
payment of the Redemption Price.

Registration  Rights  Agreement) which have been registered under the Securities
Act,  in like  principal  amount  and having  terms  identical  in all  material
respects  as the  initial  Notes.  The  Holders of the  initial  Notes  shall be
entitled  to receive  certain  additional  interest  payments  in the event such
exchange  offer  is not  consummated  and upon  certain  other  conditions,  all
pursuant and in accordance with the terms of the Registration Rights Agreement.

         If money for the  payment of  principal,  premium,  if any, 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.

12.  Discharge Prior to Redemption or Maturity.

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.

14.  Restrictive Covenants.

any  Restricted  Subsidiary  occurs and is continuing,  the Notes  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.

         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.

18.  No Recourse Against Others.

         No  incorporator or any past,  present or future partner,  stockholder,
other equity holder, 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.

                       11.50% Senior Dollar Note due 2009

1.       Principal and Interest.

         The Company will pay the principal of this Note on March 15, 2009.

         The Company  promises to pay interest on the  principal  amount of this
Note on each Interest  Payment  Date, as set forth below,  at the rate per annum
shown above.

         Interest will be payable semiannually in cash (to the holders of record
of the Notes at the close of business on the March 1 or September 1  immediately
preceding the Interest Payment Date) on each Interest  Payment Date,  commencing
March 15,  2000.  Interest  will be computed  on the basis of a 360-day  year of
twelve 30-day months.

         If an  exchange  offer  registered  under  the  Securities  Act  is not
consummated,  and a shelf  registration  statement under the Securities Act with
respect to resales of the Notes is not declared effective by the Commission,  on
or before  the date  that is six  months  after  the issue  date of this Note in
accordance  with the terms of the  Registration  Rights  Agreement,  dated as of
December 8, 1999,  between the  Company and Morgan  Stanley & Co.  Incorporated,
annual  interest  (in  addition  to  interest  otherwise  due on the Notes) will
accrue, at an annual rate of 0.5% per annum of the principal amount,  payable in
cash  semiannually,  in  arrears  on March  15 and  September  15 of each  year,
commencing  September 15, 2000 until the  consummation of a registered  exchange
offer or the  effectiveness  of a  shelf-registration  statement with respect to
resale of this Note. The Holder of this Note is entitled to the benefits of such
Registration Rights Agreement.

         The  Holder  of this  Note is  entitled  to the  benefits  of a  Pledge
Agreement, dated as of December 8, 1999, between the Company and The Bank of New
York,  as trustee (the  "Trustee"),  pursuant to which the Company has placed in
the Pledge Account cash or Government  Securities  sufficient to provide for the
payment of the first three interest payments on this Note.

         The Company  shall pay interest on overdue  principal  and premium,  if
any, and interest on overdue installments of interest,  to the extent lawful, at
a rate per annum that is 11.50% per annum.

2.       Method of Payment.

         The Company will pay principal as provided  above and interest  (except
defaulted  interest) on the principal  amount of the Notes as provided  above on
each March 15 and  September 15 to the Persons who are Holders (as  reflected in
the Note  Register  at the close of business  on such March 1 and  September  1,
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 not make payment to the Holder unless this Note is surrendered to a
Paying Agent.


<PAGE>

         The Company will pay principal, premium, if any, and as provided above,
interest  in the  currency  of the United  States that at the time of payment is
legal tender for the payment of public and private debts.  However,  the Company
may pay  principal,  premium,  if any, and interest by its check payable in such
currency.  It may mail an interest  check to a Holder's  registered  address (as
reflected  in the Note  Register).  If a  payment  date is a date  other  than a
Business  Day at a place of  payment,  payment  may be made at that place on the
next  succeeding day that is a Business Day and no interest shall accrue for the
intervening period.

3.       Paying Agent and Registrar.

         Initially,  the Trustee  will act as Paying  Agent and  Registrar.  The
Company may change any Paying 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.

4.       Indenture; Issuance of Additional Notes.

         This  Note is one of a duly  authorized  issue of Notes of the  Company
designated  its 11.50%  Senior  Dollar  Notes due 2009,  issued and to be issued
under an Indenture, dated as of December 8, 1999 (the "Indenture"),  between the

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

              2007 and thereafter                   100.000%


<PAGE>

         In addition,  at any time or from time to time on or prior to March 15,
2002,  the  Company  may,  at its  option,  redeem  up to  35% of the  aggregate
principal amount of the Notes with the net proceeds of one or more Public Equity
Offerings, at a Redemption Price (expressed as a percentage of principal amount)
of 111.500%, provided, (i) that Notes representing at least 65% of the principal
amount  of the  Notes  originally  issued  remain  outstanding  after  each such
redemption and (ii) that notice of each such redemption is mailed within 60 days
of each such Public Equity Offering.

6.       Notice of Redemption.

         Notice of any optional  redemption  will be mailed at least 30 days but
not more than 60 days before the  Redemption  Date to each Holder of Notes to be
redeemed  at his last  address  as it  appears  in the Note  Register.  Notes in
original denominations larger than $1,000 of principal amount may be redeemed in
part. On and after the Redemption  Date,  interest  ceases to accrue on Notes or
portions of Notes  called for  redemption,  unless the  Company  defaults in the
payment of the Redemption Price.

7.       Repurchase Upon Change in Control.

         Upon the  occurrence  of any Change of Control,  each Holder shall have
the right to require the repurchase of its Notes by the Company in cash pursuant
to the offer described in the Indenture at a purchase price equal to 101% of the
principal amount thereof plus accrued and unpaid  interest,  if any, to the date
of purchase (the "Change of Control Payment").

         A notice of such Change of Control will be mailed within 30
days after any Change of Control occurs to each Holder at his last address as it
appears in the Note Register. Notes in original denominations larger than $1,000
of principal amount may be sold to the Company in part. On and after the date of
the Change of Control Payment, interest ceases to accrue on Notes or portions of
Notes  surrendered for purchase by the Company,  unless the Company  defaults in
the payment of the Change of Control Payment.

8.       Registration Rights

obligated, within six months after the issue date of this Note, to consummate an

the Pledge Account cash or Government  Securities  sufficient to provide for the
payment of the first three interest payments on this Note.

         The Company  shall pay interest on overdue  principal  and premium,  if
any, and interest on overdue installments of interest,  to the extent lawful, at
a rate per annum that is 11.50% per annum.

2.       Method of Payment.

         The Company will pay principal as provided  above and interest  (except
defaulted  interest) on the principal  amount of the Notes as provided  above on
each March 15 and  September 15 to the Persons who are Holders (as  reflected in
the Note  Register  at the close of business  on such March 1 and  September  1,
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 not make payment to the Holder unless this Note is surrendered to a
Paying Agent.

         The Company will pay principal, premium, if any, and as provided above,
interest  in the  currency  of the United  States that at the time of payment is
legal tender for the payment of public and private debts.  However,  the Company
may pay  principal,  premium,  if any, and interest by its check payable in such
currency.  It may mail an interest  check to a Holder's  registered  address (as
reflected  in the Note  Register).  If a  payment  date is a date  other  than a
Business  Day at a place of  payment,  payment  may be made at that place on the
next  succeeding day that is a Business Day and no interest shall accrue for the
intervening period.

3.       Paying Agent and Registrar.

         Initially, the Trustee will act as U.S. Paying Agent and Registrar. The
Company may change any Paying 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.

4.       Indenture; Issuance of Additional Notes.

2002,  the  Company  may,  at its  option,  redeem  up to  35% of the  aggregate
principal amount of the Notes with the net proceeds of one or more Public Equity

amount  of the  Notes  originally  issued  remain  outstanding  after  each such
redemption and (ii) that notice of each such redemption is mailed within 60 days
of each such Public Equity Offering.

original denominations larger than $1,000 of principal amount may be redeemed in
part. On and after the Redemption  Date,  interest  ceases to accrue on Notes or
portions of Notes  called for  redemption,  unless the  Company  defaults in the
payment of the Redemption Price.

principal amount thereof plus accrued and unpaid  interest,  if any, to the date
of purchase (the "Change of Control Payment").

         A notice of such Change of Control will be mailed  within 30 days after
any Change of Control occurs to each Holder at his last address as it appears in

<PAGE>



Act,  in like  principal  amount  and having  terms  identical  in all  material
respects  as the  initial  Notes.  The  Holders of the  initial  Notes  shall be
entitled  to receive  certain  additional  interest  payments  in the event such
exchange  offer  is not  consummated  and upon  certain  other  conditions,  all
pursuant and in accordance with the terms of the Registration Rights Agreement.

furnish appropriate endorsements and transfer documents and to pay any taxes and
fees  required by law or  permitted by the  Indenture.  The  Registrar  need not
register the transfer or exchange of any Notes selected for redemption. Also, it
need not  register the transfer or exchange of any Notes for a period of 15 days
before a selection of Notes to be redeemed is made.

10.      Persons Deemed Owners.

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

11.      Unclaimed Money.

         If money for the  payment of  principal,  premium,  if any, 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.

12.      Discharge Prior to Redemption or Maturity.

payment at the final (but not any interim)  fixed  maturity  and such  defaulted

payment default;  (f) any final judgment or order (not covered by insurance) for
the  payment  of money in excess of $10  million in the  aggregate  for all such

Company or any Significant  Subsidiary and shall not be paid or discharged,  and

         If an Event of Default  (other  than an Event of Default  specified  in
clause (g) or (h) above that occurs with respect to the  Company)  occurs and is
continuing  under the  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,

amount of, premium,  if any, and accrued interest on the Notes to be immediately
due and payable.

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

<PAGE>



any  Restricted  Subsidiary  occurs and is continuing,  the Notes  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

power.

Affiliates as if it were not the Trustee.

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.

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 March  19,  1999,  relating  to the  Notes  (the
        "Indenture")  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,
        as 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 or sold  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, 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) 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,  (D) outside the United States in accordance with Rule 904
         of  Regulation  S under  the  Securities  Act and  Section  2.02 of the
         Indenture,  provided  this clause (D) will not be  effective  until the
         later of (i) June 8,  2000 or (ii) the date the placement  agent of the
         Note has completed its securities  distribution activities with respect
         thereto,  (E)  pursuant  to  the  provisions  of  Rule  144  under  the
         Securities Act, 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  and  the  Company  may
        reasonably  require to confirm that the proposed  sale complies with the
        foregoing  restrictions.  We further understand that the Notes purchased
        by us will bear a legend to the foregoing effect.

                4. We are an institutional  "accredited investor" (as defined in
        Rule  501(a)(1),  (2), (3) or (7) of  Regulation D under the  Securities
        Act) and have such  knowledge  and  experience in financial and business
        matters  as to be  capable  of  evaluating  the  merits and risks of our
        investment in the Notes, and we and any accounts for which we are acting
        are each able to bear the economic risk of our or its investment.

                5.  We are  acquiring  the  Notes  purchased  by us for  our own
        account or for one or more accounts  (each of which is an  institutional
        "accredited  investor") as to each of which we exercise sole  investment
        discretion.

                You and the  Company  are  entitled to rely upon this letter and
are  irrevocably  authorized  to  produce  this  letter or a copy  hereof to any
interested party in any  administrative or legal proceedings or official inquiry
