                   DEFINITIONS AND INCORPORATION BY REFERENCE

SECTION 1.1.  DEFINITIONS.

          "Accounts" means all present and future rights of the Company and each
Restricted  Subsidiary  to  payment  for goods  sold or  leased or for  services
rendered,  which are not evidenced by instruments or chattel paper,  and whether
or not earned by performance.

          "Acquired  Debt" means,  with  respect to any  specified  Person,  (i)
Indebtedness  of any other  Person  existing  at the time such  other  Person is
merged with or into or becomes a Subsidiary of such specified Person, including,
without   limitation,   Indebtedness   incurred  in   connection   with,  or  in
contemplation  of,  such  other  Person  merging  with  or into  or  becoming  a
Subsidiary  of such  specified  Person and (ii)  Indebtedness  secured by a Lien
encumbering any asset acquired by such specified Person.

          "Affiliate" of any specified Person means any other Person directly or
indirectly  controlling  or  controlled  by or under  direct or indirect  common
control with such specified Person.  For purposes of this definition,  "control"
(including,  with correlative meanings, the terms "controlling," "controlled by"
and "under common control with"), as used with respect to any Person,  will mean
the  possession,  directly  or  indirectly,  of the power to direct or cause the
direction  of the  management  or policies of such Person,  whether  through the

<PAGE>

          "Agent" means any Registrar or Paying Agent.

          "Applicable Law," except as the context may otherwise  require,  means
all  applicable  laws,  rules,  regulations,   ordinances,  judgments,  decrees,
injunctions,  writs and orders of any court or governmental  agency or authority
and rules,  regulations,  orders,  licenses and permits of any United  States or
Brazilian federal, state, provincial, municipal, regional, or other governmental
body,  instrumentality,  agency or authority, in each case in any way applicable

or use  thereof) and with  respect to ITSA Ltd.,  the Company or any  Guarantor,
such  Person's  "Estatutos  Sociales,"  Articles of  Association,  Memorandum of
Association and/or other organizational or governing documents.

          "Asset  Sale"  means  (i)  the  sale,   lease,   conveyance  or  other
disposition of any assets or rights (including,  without limitation, by way of a

the ordinary course of business  consistent  with past  practices;  and (ii) the
issuance or sale by the Company or any of its Restricted  Subsidiaries of Equity
Interests of any of the Company's Restricted  Subsidiaries.  Notwithstanding the
foregoing, none of the following will be deemed an Asset Sale: (a) a transfer of
assets by the Company to a  Restricted  Subsidiary  that is a Guarantor  or by a
Restricted Subsidiary to the Company or to another Restricted Subsidiary that is
a Guarantor;  (b) a Restricted  Payment that is permitted under Section 4.7; (c)
dispositions  in any fiscal year with Net  Proceeds in the  aggregate  amount of
US$500,000 (or the equivalent  thereof at time of determination) or less; (d) an

received for such sales or other dispositions; and (k) sales or issuances of the
Capital  Stock of a Restricted  Subsidiary  to Persons other than the Company or
another  Restricted  Subsidiary in consideration of the transfer or contribution
to the  Restricted  Subsidiary of assets that (i) have a value at least equal to
the Fair Market Value of such Capital Stock at the time of such  transaction and
(ii)  would  constitute  a  Related  Business  Investment  if  acquired  by such
Restricted Subsidiary with Net Proceeds of an Asset Sale; PROVIDED that, if such
Restricted  Subsidiary  is a Guarantor,  such sale or issuance of Capital  Stock
will not impair the Guarantee given by such Restricted Subsidiary and, PROVIDED,
further, that the acquisition of such assets constitutes a Permitted Investment.

          "Asset Swap" means the  execution of a definitive  agreement,  subject
only to  approvals of the Ministry of  Communications  or such other  applicable
Brazilian   governmental   authority  or  agency  and  other  customary  closing
conditions,  that the Company in good faith  believes will be  satisfied,  for a
substantially  concurrent purchase and sale, or exchange,  of Telecommunications
Assets  between the Company or any of its  Restricted  Subsidiaries  and another
Person or group of Persons who are Affiliates of one another;  PROVIDED that any
amendment to or waiver of any closing  condition  which  individually  or in the
aggregate is material to the Asset Swap will be deemed to be a new Asset Swap.

          "Attributable  Debt" in  respect of a sale and  leaseback  transaction
means, at the time of  determination,  the present value (discounted at the rate
of interest implicit in such transaction, determined in accordance with GAAP) of
the obligation of the lessee for net rental  payments  during the remaining term
of the lease  included in such sale and  leaseback  transaction  (including  any

                                    THE NOTES

SECTION 2.1.  FORM AND DATING.

          (a)  Provisions  relating  to the Notes are set forth in this  Section
2.1. The Notes shall be  substantially  in the form of Exhibit A hereto which is
hereby  incorporated in and expressly made a part of this  Indenture.  Each Note
shall be dated the date of its authentication.

          (b) Global Notes. Notes issued to a Person who has an account with, or
is a member of, the Depository (a  "Participant")  shall be issued  initially in
the form of one or more permanent  global Notes in definitive,  fully registered
form  without  interest  coupons  with the  global  securities  legend and other
securities legend set forth in Exhibit A hereto (each, a " Global Note"),  which
shall be  deposited  on behalf of the Holders of the Notes  represented  thereby
with the Note  Custodian,  and  registered  in the name of the  Depository  or a
nominee of the Depository, duly executed by the Company and authenticated by the
Trustee as hereinafter  provided.  The aggregate  principal amount of the Global
Notes may from time to time be increased or decreased by adjustments made on the
records of the Trustee and the Depository or its nominee, as the case may be, as
hereinafter provided.

          (c) Book-Entry Provisions. This Section 2.1(c) shall apply only to the
Global Notes deposited with or on behalf of the Depository.

          The Company shall execute and the Trustee  shall,  in accordance  with
this Section 2.1(c), authenticate and deliver initially one or more Global Notes
that (a) shall be registered in the name of the Depository or the nominee of the
Depository  and (b) shall be  delivered  by the  Trustee  to the  Depository  or
pursuant to the  Depository's  instructions  or held by the Trustee as custodian
for the Depository.

          Participants shall have no rights under this Indenture with respect to
any Global Note held on their behalf by the  Depository or by the Trustee as the
custodian of the Depository or under such 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 authorization furnished by the Depository
or impair,  as between the  Depository  and its  Participants,  the operation of
customary practices of such Depository governing the exercise of the rights of a
holder of a beneficial interest in any Global Note.

          (d)  Certificated  Notes.  Except as  provided  in this  Section  2.1,
Section 2.6 or Section 2.7, owners of beneficial  interests in Global Notes will
not be entitled to receive physical delivery of Certificated Notes. Notes issued
to a Person who is not a Participant  or will not be holding the Notes through a
Participant  will  receive  Certificated  Notes;  PROVIDED,  HOWEVER,  that upon
transfer of such Certificated Notes to a Participant or a Person holding through
a Participant, such Certificated Notes will, unless the relevant Global Note has
previously  been  exchanged,  be  exchanged  for an  interest  in a Global  Note
pursuant to the provisions of Section 2.6.

          (e) Provisions  Applicable to Forms of Notes.  The Notes may also have
such additional  provisions,  omissions,  variations or substitutions as are not
inconsistent  with the provisions of this Indenture,  and may have such letters,
numbers or other marks of identification and such legends or endorsements placed
thereon as may be required to comply with this Indenture,  any Applicable Law or
with  any  rules  made  pursuant  thereto  or with the  rules of any  securities
exchange or governmental agency or as may be determined consistently herewith by
the Officer of the Company  executing such Notes, as  conclusively  evidenced by
his/her  execution  of such  Notes.  All Notes will be  otherwise  substantially
identical except as provided herein.

                                       16
<PAGE>

          Subject to the provisions of this Article 2, a registered  Holder of a
beneficial  interest in a Global Note may grant proxies and otherwise  authorize
any  Person to take any  action  that a Holder is  entitled  to take  under this
Indenture or the Notes.

SECTION 2.2.  EXECUTION AND AUTHENTICATION.

          An Officer  will sign the Notes for the Company by manual or facsimile
signature.  The  Company's  seal may be  reproduced  on the  Notes and may be in
facsimile form.

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

          A Note will not be valid or obligatory  for any purpose or entitled to
the benefits of this Indenture until  authenticated  by the manual  signature of
the  Trustee or its  authenticating  agent.  The  signature  will be  conclusive
evidence that the Note has been authenticated under this Indenture.

          The Trustee shall authenticate and deliver Notes for original issue in
an  aggregate  principal  amount of  US$35,000,000  upon a written  order of the
Company signed by two Officers. Such order shall specify the amount of the Notes
to be authenticated and the date on which the original issue of securities is to
be  authenticated.  The aggregate  principal amount of Notes  outstanding at any
time may not exceed  US$35,000,000  except (i) as provided in Section  2.8,  and
(ii) that the  principal  amount of the Notes  will  increase  if, on any of the
first four Interest  Payment Dates occurring after the date hereof,  interest on
the Notes is, at the  option of the  Company,  to be paid in kind  instead of in
cash. Upon such an event,  the Company will issue to each Holder of the Notes on
any such  Interest  Payment  Date,  and the Trustee  will  authenticate,  upon a
written  order  of the  Company  signed  by two  Officers,  an  additional  Note
substantially  in the form set forth in Exhibit A registered in the name of such
Holder and having a principal  amount  equal to the amount of  interest  paid in
kind  on all of the  outstanding  Notes  held by such  Holder  on such  Interest
Payment Date.

          The Trustee may appoint an authenticating agent reasonably  acceptable
to the Company to authenticate Notes.

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

                                       17

SECTION 2.3.  TRUSTEE, REGISTRAR AND PAYING AGENT.

          The  Company  will  maintain  an office or agency  where  Notes may be
presented  for  registration  of transfer or for exchange  ("Registrar")  and an
office or agency where Notes may be presented for payment ("Paying Agent").  The
Registrar will keep a register  ("Register")  of the Notes and of their transfer
and  exchange.  The  Company  may also  from  time to time  appoint  one or more
co-registrars  and one or more additional  paying agents.  The term  "Registrar"
includes any  co-registrar  and the term "Paying Agent"  includes any additional
paying agent. The Company may change any Paying Agent or Registrar in accordance
with the terms of the Amended and Restated Paying Agent  Agreement,  dated as of
July 20, 2000, among the Company,  Deutsche Trust Bank Limited and Deutsche Bank
AG  London,  as the same may be  amended  from time to time (the  "Paying  Agent
Agreement").  The  Company  will  notify the  Trustee in writing of the name and
address of any Paying Agent not a party to this Indenture.  If the Company fails
to appoint or maintain  another entity as Registrar or Paying Agent, the Trustee
will act,  subject to the last  paragraph  of this  Section  2.3,  as such.  The
Company  or any of its  Subsidiaries  may  act as  Paying  Agent  or  Registrar;
PROVIDED,  HOWEVER, that none of the Company, its Subsidiaries or the Affiliates
of the foregoing  will act (i) as Paying Agent in connection  with  redemptions,
offers to purchase,  discharges and defeasance,  as otherwise  specified in this
Indenture,  and (ii) as  Paying  Agent or  Registrar  if a  Default  or Event of
Default has occurred and is continuing.

          The Company  hereby  appoints The Bank of New York,  at its  Corporate
Trust Office,  as the Trustee  hereunder and The Bank of New York hereby accepts
such appointment.  The Trustee will have the powers and authority granted to and
conferred  upon it in the Notes and hereby and such further powers and authority
to act on behalf of the  Company as may be  mutually  agreed upon by the Company
and the Trustee,  and the Trustee will keep a copy of this  Indenture  available
for inspection during normal business hours at its Corporate Trust Office.

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

          The Company initially appoints the Trustee to act as the Registrar and
to act as Note Custodian  with respect to the Global Notes.  Deutsche Trust Bank
Limited will continue to act in its capacity as principal  Paying Agent pursuant
to the terms and conditions of the Paying Agent Agreement.

          All of the  terms and  provisions  with  respect  to such  powers  and
authority  contained  in the Notes are subject to and  governed by the terms and
provisions hereof.

          The Trustee may resign as Registrar or Paying  Agent,  if  applicable,
upon 30 calendar days prior written notice to the Company.

SECTION 2.4.  PAYING AGENT TO HOLD MONEY IN TRUST.

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

SECTION 2.5.  HOLDER LISTS.

          The  Trustee  will  preserve  in as  current  a form as is  reasonably
practicable  the most recent list  available to it of the names and addresses of
all Holders pursuant to TIA Section 312(a). If the Trustee is not the Registrar,

                                       18
<PAGE>

the Company will furnish to the Trustee at least seven Business Days before each
Interest  Payment  Date and at such other  times as the  Trustee  may request in
writing,  a list in such form and as of such date as the  Trustee may require of
the names and  addresses of the Holders of Notes and the Company  will  strictly
comply with TIA Section 312(a).

SECTION 2.6.  TRANSFER AND EXCHANGE.

          (a) Transfer and Exchange of Certificated Notes. If Certificated Notes
are presented by a Holder to the Registrar with a request:

          (i) to register the transfer of the Certificated Notes; or

          (ii) to exchange such Certificated Notes for an equal principal amount
of Certificated Notes of other authorized denominations,

the  Registrar  will  register the transfer or make the exchange as requested if
its requirements  for such  transactions are met;  PROVIDED,  HOWEVER,  that the
Certificated Notes presented or surrendered for register of transfer or exchange
shall be duly endorsed or  accompanied  by a written  instruction of transfer in
form  satisfactory  to the  Registrar  duly  executed  by such Holder or by such
Holder's attorney, duly authorized in writing.

          (b) Restrictions on Transfer of a Certificated Note for a beneficial
interest  in a Global  Note.  A  Certificated  Note may not be  exchanged  for a
beneficial   interest  in  a  Global  Note  except  upon   satisfaction  of  the
requirements  set forth  below.  Upon  receipt by the Trustee of a  Certificated
Note,  duly endorsed or accompanied by appropriate  instruments of transfer,  in
form satisfactory to the Trustee, together with:

          (i   certification  from the Holder thereof (in substantially the form
               of  Exhibit  B  hereto)  that  such  Certificated  Note is  being
               transferred   to  a  Participant   or  will  be  held  through  a
               Participant; and

          (ii  written  instructions  from  the  Holder  thereof  directing  the
               Trustee to make,  or to direct  the Note  Custodian  to make,  an
               adjustment  on its books and records  with  respect to the Global
               Note to reflect an increase in the aggregate  principal amount of
               the Notes  represented by such Global Note, such  instructions to
               contain  information  regarding  the  Depository  account  to  be
               credited with such increase;

then the Trustee shall cancel such  Certificated  Note and cause,  or direct the
Note  Custodian  to cause,  in  accordance  with the standing  instructions  and
procedures existing between the Depository and the Note Custodian, the aggregate
principal amount of Notes  represented by the Global Note to be increased by the
aggregate  principal amount of the  Certificated  Note to be exchanged and shall
credit or cause to be credited to the  account of the Person  specified  in such
instructions  a beneficial  interest in such Global Note equal to the  principal
amount of the Certificated  Note so canceled.  If no applicable Global Notes are
then  outstanding,  the Company shall issue and the Trustee shall  authenticate,
upon written order of the Company in the form of an Officers' Certificate, a new
Global Note in the appropriate principal amount.

          (c  Transfer  and  Exchange  of Global  Notes.  (i) The  transfer  and
exchange  of  Global  Notes or  beneficial  interests  in Global  Notes  will be
effected  through the Depository,  in accordance with this Indenture  (including
applicable restrictions on transfer set forth herein, if any) and the procedures
of the Depository  therefor.  A transferor of a beneficial  interest in a Global
Note to another Global Note shall deliver to the  Registrar:  (A) if applicable,
instructions given in accordance with the Depository's  procedures directing the
Trustee  to  credit  or  cause  to be  credited  a  beneficial  interest  in the
applicable  Global  Note in an amount  equal to the  beneficial  interest in the
Global Note to be exchanged;  and (B) a written  order given in accordance  with
the Depository's  procedures  containing  information  regarding the Participant
account of the Depository to be credited with such increase.

          The Registrar  shall, in accordance with such  instructions,  instruct
the Depository to increase and reduce,  as applicable,  the principal  amount of
each applicable  Global Note to the extent required and to credit to the account
of the Person  specified  in such  instructions  a  beneficial  interest  in the
applicable  Global Note and to debit from the  account of the Person  making the
transfer the beneficial interest in the Global Note being transferred.

                                       19
<PAGE>

          (ii) Notwithstanding  any provision of this Indenture  (other than the
               provisions  set forth in Section  2.7),  a Global Note may not be
               transferred  as a whole except by the  Depository to a nominee of
               the  Depository  or  by  a  nominee  of  the  Depository  to  the
               Depository  or  another  nominee  of  the  Depository  or by  the
               Depository  or any such  nominee to a successor  Depository  or a
               nominee of such successor Depository.

          (d  Transfer  of  a  Beneficial  Interest  in  a  Global  Note  for  a
Certificated Note. (i) Any person having a beneficial  interest in a Global Note
may transfer such  beneficial  interest in the form of a Certificated  Note to a
Person that is acquiring the Note and is not a Participant or is not holding the
Note through a Participant  upon receipt by the Trustee of an instruction,  duly
endorsed  or  accompanied  by  appropriate  instruments  of  transfer,  in  form
satisfactory to the Trustee,  together with written instructions from the Holder
thereof  directing the Trustee to make, or to direct the Note Custodian to make,
an  adjustment  on its books and  records  with  respect to the  Global  Note to
reflect a decrease in the aggregate principal amount of the Notes represented by
such  Global  Note,  such  instructions  to contain  information  regarding  the
Participant  account  to be  debited  with such  decrease.  Upon  receipt by the
Trustee of such instructions and instruments, the Trustee or the Note Custodian,
at the direction of the Trustee,  will cause,  in  accordance  with the standing
instructions  and  procedures  existing  between  the  Depository  and the  Note
Custodian,  the aggregate  principal  amount of the Global Note to be reduced on
its books and records and,  following such  reduction,  the Company will execute
and the Trustee will authenticate, upon a written order of the Company signed by
two Officers,  and deliver to the  transferee a  Certificated  Note equal to the
principal amount of the Global Note being reduced.

          (ii) Certificated  Notes issued in exchange for a beneficial  interest
               in a  Global  Note  pursuant  to this  Section  2.6(d)  shall  be
               registered in such names and in such authorized  denominations as
               the Depository, pursuant to instructions from its Participants or
               otherwise,  shall instruct the Trustee. The Trustee shall deliver
               such Certificated  Notes to the persons in whose names such Notes
               are so  registered  in accordance  with the  instructions  of the
               Depository.

          (e  Authentication of Certificated  Notes in Absence of Depository. If
at any time:

          (i)  the  Depository  for the  Notes  notifies  the  Company  that the
               Depository is unwilling or unable to continue as  Depository  for

Notes,  redeemed,  repurchased or canceled, all Global Notes will be returned to

2.12 hereof. At any time prior to such cancellation,  if any beneficial interest
in a Global Note is exchanged for Certificated Notes,  redeemed,  repurchased or
canceled,  the principal amount of Notes represented by such Global Note will be
reduced  accordingly and an endorsement will be made on such Global Note, by the
Trustee or the Note Custodian,  at the direction of the Trustee, to reflect such
reduction.

          (h General Provisions Relating to Transfers and Exchanges.

          (i   To permit  registrations of transfers and exchanges,  the Company
               will execute and the Trustee will authenticate Certificated Notes
               and Global Notes at the Registrar's request.

          (ii  No service  charge will be made to a Holder for any  registration
               of transfer or exchange, 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  similar  governmental  charge  payable  upon
               exchange or transfer  pursuant to Sections 2.2,  2.11,  3.6, 3.7,

               Trustee will authenticate  Certificated Notes and Global Notes in
               accordance with the provisions of Section 2.2 hereof.

SECTION 2.7.  CERTIFICATED NOTES.

          (a  A Global Note deposited with the Depository or with the Trustee as
custodian for the Depository pursuant to Section 2.1 shall be transferred to the
beneficial  owners  thereof in the form of  Certificated  Notes in an  aggregate
principal  amount equal to the principal amount of such Global Note, in exchange
for such Global Note,  only if such  transfer  complies with Section 2.6 and (i)
the  Depository  notifies the Company that it is unwilling or unable to continue
as Depository for such Global Note or if at any time such  Depository  ceases to
be a  "clearing  agency"  registered  under  the  Exchange  Act and a  successor
depository  is not  appointed  by the Company  within 90  calendar  days of such
notice,  or (ii) an Event of Default has occurred and is continuing or (iii) the
Company, in its sole discretion,  notifies the Trustee in writing that it elects
to cause the issuance of Certificated Notes under this Indenture.

          (b  Any Global  Note that is  transferable  to the  beneficial  owners
thereof  pursuant to this Section 2.7 shall be  surrendered by the Depository to
the Trustee located in the Borough of Manhattan,  The City of New York, to be so
transferred,  in whole or from  time to time in part,  without  charge,  and the
Trustee shall  authenticate,  upon a written order of the Company  signed by two
Officers,  and deliver,  upon such transfer of each portion of such Global Note,
an  equal  aggregate  principal  amount  of  Certificated  Notes  of  authorized
denominations. Any portion of a Global Note transferred pursuant to this Section
2.7 shall be executed,  authenticated  and delivered  only in  denominations  of
$1,000 and any integral  multiple  thereof and  registered  in such names as the
Depository shall direct.

          (c  In the event of the  occurrence of any of the events  specified in
Section  2.7(a),  the Company  will  promptly  make  available  to the Trustee a
reasonable  supply of Certificated  Notes in definitive,  fully  registered form
without interest coupons.

SECTION 2.8.  REPLACEMENT NOTES.

          If any mutilated Note is  surrendered  to the Trustee,  or the Company
and the Trustee receive evidence to their satisfaction of the destruction,  loss
or theft of any Note, the Company will,  upon the written  request of the Holder
thereof,  issue and the Trustee, upon the written order of the Company signed by
two  Officers  of the  Company,  will  authenticate  a  replacement  Note if the
Trustee's  requirements  are met. If required by the Trustee or the Company,  an
indemnity  bond  must be  supplied  by such  Holder  that is  sufficient  in the
judgment of the Trustee and the Company to protect the Company, the Trustee, any
Agent and any authenticating  agent from any loss that any of them may suffer if
a Note is replaced. The Company may charge for its expenses in replacing a Note.

                                       22
<PAGE>

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

          The provisions of this Section 2.8 are exclusive and will preclude (to
the extent lawful) all other rights and remedies with respect to the replacement
or payment of mutilated, destroyed, lost or stolen Notes.

SECTION 2.9.  OUTSTANDING NOTES.

          The Notes  outstanding at any time are all the Notes  authenticated by
the Trustee except for those canceled by it (or its agent),  those  delivered to
it (or its agent) for cancellation, those reductions in the interest in a Global
Note effected by the Trustee in accordance with the provisions hereof, and those
described  in this  Section as not  outstanding.  Except as set forth in Section
2.10 hereof,  a Note does not cease to be outstanding  because the Company or an
Affiliate of the Company holds the Note.

          If a Note is replaced  pursuant to Section 2.8 hereof, it ceases to be
outstanding  unless  the  Trustee  receives  proof  satisfactory  to it that the
replaced Note (other than a mutilated Note  surrendered for replacement) is held
by a bona  fide  purchaser  (as such term is  defined  in  Section  8-302 of the
Uniform Commercial Code as in effect in the State of New York).

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

          If  the  Paying   Agent   (other  than  the  Company  or  any  of  its
Subsidiaries)  holds,  on a  redemption  date  or  maturity  date,  cash or Cash
Equivalents sufficient to pay Notes payable on that date, then on and after that
date such  Notes  will be deemed to be no longer  outstanding  and will cease to
accrue interest.

SECTION 2.10.  TREASURY NOTES.

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

SECTION 2.11.  TEMPORARY NOTES.

          Until  Certificated  Notes are ready for  delivery,  the  Company  may
prepare and the Trustee will  authenticate  temporary Notes upon a written order
of the Company  signed by two Officers of the Company.  Temporary  Notes will be
substantially in the form of Certificated Notes but may have variations that the
Company  considers  appropriate  for  temporary  Notes and as will be reasonably
acceptable to the Trustee.  Without unreasonable delay, the Company will prepare
and the Trustee will authenticate, upon a written order of the Company signed by
two Officers, Certificated Notes in exchange for temporary Notes.

          Until such  exchange,  Holders of temporary  Notes will be entitled to
all of the benefits of this Indenture.

SECTION 2.12.  CANCELLATION.

          The Company at any time may deliver  Notes to the Trustee or its Agent
for cancellation. The Registrar and Paying Agent will forward to the Trustee any
Notes surrendered to them for registration of transfer, exchange or payment. The
Trustee  (or its Agent) and no one else will  cancel all Notes  surrendered  for
registration of transfer,  exchange,  payment,  replacement or cancellation  and
will  dispose  of  canceled  Notes in  accordance  with its  procedures  for the
disposition of canceled  securities in effect as of the date of such disposition
(subject to the record retention requirement of the Exchange Act). Certification

                                       23
<PAGE>

of the  disposition  of all canceled Notes will be delivered to the Company from
time to time.  The Company may not issue new Notes to replace  Notes that it has
paid or that have been delivered to the Trustee (or its Agent) for cancellation.
If the Company acquires any of the Notes, such acquisition will not operate as a
redemption or satisfaction of the indebtedness  represented by such Notes unless
and  until  the  same  are  surrendered  to  the  Trustee  (or  its  Agent)  for
cancellation pursuant to this Section 2.12.

SECTION 2.13.  DEFAULTED INTEREST.

          If the Company defaults in a payment of interest on the Notes, it will
pay the  defaulted  interest in any lawful  manner plus,  to the extent  lawful,
interest payable on the defaulted interest,  to the Persons who are Holders on a
subsequent  special  record date, in each case at the rate provided in the Notes
and in Section 4.1 hereof. The Company will notify the Trustee in writing of the
amount of  defaulted  interest  proposed to be paid on each Note and the date of
the  proposed  payment.  The  Company  will fix or cause to be fixed  each  such
special record date and payment date,  PROVIDED that no such special record date
will be less than 10 calendar  days prior to the related  payment  date for such
defaulted  interest.  At least 15 calendar days before the special  record date,
the Company (or,  upon the written  request of the  Company,  the Trustee in the
name and at the  expense  of the  Company)  will  mail or cause to be  mailed to
Holders a notice that states the special record date,  the related  payment date
and the amount of such defaulted interest to be paid.

SECTION 2.14.  PERSONS DEEMED OWNERS.

          Prior to due  presentment  for the  registration  of a transfer of any
Note,  the Trustee,  any Agent,  the Company and any agent of the foregoing will
deem and treat the Person in whose name any Note is  registered  as the absolute
owner of such Note for all purposes  (including the purpose of receiving payment
of principal of and interest on such Note; PROVIDED that defaulted interest will
be paid as set forth in Section 2.13),  and none of the Trustee,  any Agent, the
Company  or any  agent  of the  foregoing  will be  affected  by  notice  to the
contrary.

SECTION 2.15.  CUSIP NUMBERS.

          Pursuant to a  recommendation  promulgated by the Committee on Uniform
Security Identification  Procedures, the Company will print CUSIP numbers on the
Notes,  and the  Trustee  may use CUSIP  numbers in notices  of  redemption  and
purchase as a convenience to Holders;  PROVIDED,  HOWEVER, that any such notices
may state that no  representation  is made as to the correctness of such numbers
as  printed  on the Notes  and that  reliance  may be  placed  only on the other
identification numbers printed on the Notes, and any such redemption or purchase
will not be affected by any defect or omission in such numbers.

                            REDEMPTION AND PREPAYMENT

SECTION 3.1.  NOTICES TO TRUSTEE.

          If the  Company  elects  to  redeem  Notes  pursuant  to the  optional
redemption  provisions of Section 3.7 hereof, it will furnish to the Trustee, at
least 30 days but not more than 60 days before a redemption  date,  an Officers'
Certificate  setting  forth (i) the clause of Section 3.7  pursuant to which the
redemption will occur,  (ii) the redemption  date, (iii) the principal amount of
Notes to be redeemed,  (iv) the redemption price and accrued and unpaid interest
and (v) whether it requests the Trustee to give notice of such  redemption.  Any
such  notice may be  canceled at any time prior to the mailing of notice of such
redemption to any Holder and will thereby be void and of no effect.

SECTION 3.2.  SELECTION OF NOTES TO BE REDEEMED.

          If less  than all of the  Notes are to be  redeemed  at any time,  the
Trustee  will select the Notes to be redeemed  among the Holders of the Notes in
compliance  with the  requirements  of any applicable  Depository and securities
exchange  requirements or, if the Notes are not so listed,  on a pro rata basis,

                                       24
<PAGE>

by lot or in  accordance  with any other method the Trustee  considers  fair and
appropriate  and in such manner as complies with any such  requirements  and any
applicable legal requirements; PROVIDED that no Notes of $1,000 principal amount
or less will be redeemed in part. In the event of partial redemption by lot, the
particular  Notes to be redeemed  will be selected,  unless  otherwise  provided
herein,  not less than 30 nor more than 60 days prior to the redemption  date by
the Trustee from the outstanding Notes not previously called for redemption.

          The Trustee will  promptly  notify the Company in writing of the Notes
selected  for  redemption  and,  in the case of any Note  selected  for  partial
redemption,  the principal amount thereof to be redeemed.  Notes and portions of
Notes selected will be in amounts of $1,000 or whole multiples of $1,000; except
that if all of the Notes of a Holder are to be redeemed,  the entire outstanding
amount of Notes held by such Holder,  even if not a multiple of $1,000,  will be
redeemed.  Except as  provided in the  preceding  sentence,  provisions  of this
Indenture  that apply to Notes called for  redemption  also apply to portions of
Notes called for redemption.

SECTION 3.3.  NOTICE OF REDEMPTION.

          At least 30 days but not more than 60 days before a  redemption  date,
the Company  will mail or cause to be mailed,  by first class mail,  a notice of
redemption  to each  Holder  whose  Notes are to be  redeemed  at such  Holder's
registered address.

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

          (a the redemption date;

          (b the redemption price and accrued and unpaid interest;

          (c if any Note is being redeemed in part, the portion of the principal
amount of such Note to be  redeemed  and that,  after the  redemption  date upon
surrender  of such Note,  a new Note or Notes in  principal  amount equal to the
unredeemed portion will be issued upon cancellation of the original Note;

          (d the name and address of the Paying Agent;

          (e that Notes called for redemption  must be surrendered to the Paying
Agent to collect the redemption price;

          (f that,  unless  the  Company  defaults  in  making  such  redemption
payment,  interest on Notes called for redemption  ceases to accrue on and after
the redemption date and the only remaining right of the Holders of such Notes is
to receive payment of the redemption price upon surrender to the Paying Agent of
the Notes redeemed;

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

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

          At the  Company's  request,  the  Trustee  will  give  the  notice  of
redemption in the Company's name and at its expense; PROVIDED, HOWEVER, that the
Company  will  have  delivered  to the  Trustee,  at least 40 days  prior to the
redemption  date (unless a shorter  period is  acceptable  to the  Trustee),  an
Officers'  Certificate  requesting that the Trustee give such notice and setting
forth the  information  to be stated in such notice as provided in the preceding
paragraph.

                                       25
<PAGE>

SECTION 3.4.  EFFECT OF NOTICE OF REDEMPTION.

          Unless otherwise  stated therein,  once notice of redemption is mailed
in  accordance  with  Section 3.3 hereof,  Notes  called for  redemption  become
irrevocably due and payable on the redemption date at the redemption price.

SECTION 3.5.  DEPOSIT OF REDEMPTION PRICE.

          On or prior to the redemption  date, the Company will deposit with the
Paying  Agent  (other  than  the  Company  or  any of  its  Subsidiaries)  money
sufficient in immediately  available  funds to pay the redemption  price of, and
accrued  interest on all,  Notes to be redeemed on that date.  The Paying  Agent
will promptly return to the Company any money deposited with the Paying Agent by
the Company in excess of the amounts  necessary to pay the redemption  price of,
and accrued interest on, all Notes to be redeemed.  If the money is deposited on
the redemption date, such deposit will be made by 11:00 a.m. New York City time.

          If  the  Company   complies  with  the  provisions  of  the  preceding
paragraph,  on and after the redemption  date,  interest will cease to accrue on
the Notes or the  portions of Notes  called for  redemption  whether or not such
Notes are presented for payment,  and the only remaining right of the Holders of
such Notes will be to receive payment of the redemption  price upon surrender to
the Paying  Agent of the Notes  redeemed.  If a Note is  redeemed on or after an
interest record date but on or prior to the related  interest payment date, then
any  accrued and unpaid  interest  will be paid to the Person in whose name such
Note was  registered  at the close of business on such record date.  If any Note
called for redemption will not be so paid upon surrender for redemption  because
of the failure of the Company to comply with the preceding  paragraph,  interest
will be paid on the  unpaid  principal  from  the  redemption  date  until  such
principal  is paid and to the extent  lawful,  on any  interest not paid on such
unpaid principal,  in each case at the rate provided in the Notes and in Section
4.1 hereof.

SECTION 3.6.  NOTES REDEEMED IN PART.

          Upon  surrender  of a Note that is redeemed in part,  the Company will
issue and, upon the Company's written request, the Trustee will authenticate for
the Holder at the expense of the Company a new Note equal in principal amount to
the unredeemed portion of the Note surrendered.

SECTION 3.7.  OPTIONAL REDEMPTION.

          (a) The Notes  will be  subject  to  redemption  at the  option of the
Company,  in  whole or in part,  upon  not less  than 30 nor more  than 60 days'
notice,  at the redemption prices (expressed as percentages of principal amount)
set forth  below,  plus  accrued  and unpaid  interest,  if any,  thereon to the
applicable redemption date, if redeemed during the twelve month period beginning
on December 20 of the years indicated below:

2003 and thereafter                      100.0000%

          (b Any  redemption  pursuant to this Section 3.7 will be made pursuant
to the provisions of Sections 3.1 through 3.6 hereof.

SECTION 3.8.  MANDATORY REDEMPTION.

          Except as set forth under  Sections 4.10 and 4.14 hereof,  the Company
will not be required to make mandatory  redemption or sinking fund payments with

accrued interest) in excess of the amounts paid on the Notes.

          The Company will pay interest (including post-petition interest in any

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.

          (b The  provisions of Section 4.7(a) will not prohibit (i) the payment

a  Default.   For  purposes  of  making  such  determination,   all  outstanding
Investments by the Company and its Restricted Subsidiaries (except to the extent
repaid in cash) in the Subsidiary so designated  will be deemed to be Restricted
Payments at the time of such  designation  and will reduce the amount  available
for Restricted  Payments under Section 4.7(a). All such outstanding  Investments
will be deemed to  constitute  Investments  in an amount equal to the greater of
(i) the net book value of such Investments at the time of such designation, (ii)
the Fair Market Value of such  Investments at the time of such  designation  and
(iii) the original Fair Market Value of such  Investments  at the time they were
made. Such designation  will only be permitted if such Restricted  Payment would
be permitted at such time and if such Restricted  Subsidiary otherwise meets the
definition  of an  Unrestricted  Subsidiary.  Upon  being  so  designated  as an
Unrestricted  Subsidiary,  any Guarantee  which was previously  executed by such
Unrestricted Subsidiary will be deemed terminated.

of the  Board  of  Directors  of  the  Company  and  described  in an  Officers'
Certificate  delivered to the Trustee) on the date of the Restricted  Payment of
the  asset(s)  proposed  to be  transferred  by the  Company  or any  Restricted
Subsidiary,  as the case may be, pursuant to the Restricted  Payment.  Not later

the Company will deliver to the Trustee an  Officers'  Certificate  stating that
all Restricted Payments during such quarter were permitted and setting forth the
basis upon which the  calculations  required by this Section 4.7 were  computed,
which  calculations may be based upon the Company's  latest available  financial
statements.

by the Company or any of its Restricted Subsidiaries as in effect at the time of
such  acquisition  (except to the  extent  such  Indebtedness  was  incurred  in
connection with or in contemplation of such  acquisition),  which encumbrance or
restriction is not applicable to any Person,  or the properties or assets of any
Person,  other than the Person,  or the  property  or assets of the  Person,  so

than  those  contained  in  the  agreements  governing  the  Indebtedness  being
refinanced or (H)  provisions  in  agreements  with other persons who own Equity
Interests in a  Restricted  Subsidiary  which have the effect of requiring  that
transactions  described  in clauses  (ii) or (iii) above be effected on terms no
more  favorable to the Company or its  Restricted  Subsidiaries  than a PRO RATA
basis in accordance with Equity Interests owned in such Restricted Subsidiary.

         (a) The  Company  will not,  and will not permit any of its  Restricted

               Indebtedness  to a Person  that is not  either  the  Company or a

               any Indebtedness that is permitted by the terms of this Indenture
               to be  outstanding  or for  the  purpose  of  fixing  or  hedging

SECTION 4.10.  LIMITATION ON ASSET SALES.

          (a) The Company  will not,  and will not permit any of its  Restricted
Subsidiaries  to,  engage  in an  Asset  Sale  unless  (i) the  Company  or such
Restricted Subsidiary, as the case may be, receives consideration at the time of
such Asset Sale at least equal to the Fair Market  Value  (which,  if it exceeds
US$1,000,000  (or the  equivalent  thereof  at time of  determination),  will be
determined  by, and set forth in, a resolution  of the Board of Directors of the
Company and described in an Officers'  Certificate  of the Company  delivered to
the  Trustee)  of the  assets or Equity  Interests  issued or sold or  otherwise
disposed  of, (ii) at least 75% of the  consideration  therefor  received by the
Company  or  such  Restricted  Subsidiary  is  in  the  form  of  cash  or  Cash

such  Restricted  Subsidiary's  most recent balance sheet) of the Company or any
Restricted  Subsidiary  (other than contingent  liabilities and liabilities that
are by their terms  subordinated  to the Notes) that are  canceled or assumed by
the  transferee of any such assets  pursuant to a customary  novation  agreement
that releases the Company or such Restricted  Subsidiary from further liability,
and (2) notes or other  obligations  received by the Company or such  Restricted
Subsidiary from such  transferee that are promptly (but in any event,  within 30
calendar days) converted by the Company or such Restricted  Subsidiary into cash
or Cash Equivalents (to the extent of the cash or Cash Equivalents  received) in
each case will be deemed to be cash or Cash  Equivalents  for  purposes  of this
provision,  (iii)  such  Asset  Sale is not  made by the  Company  to any of its
Restricted  Subsidiaries,   (iv)  the  Company  shall  cause  the  Net  Proceeds
consisting  of  cash or Cash  Equivalents  received  in  respect  thereof  to be
deposited  in the  Collateral  Account and the other  consideration  received to
become  Collateral  as and when  received  by the  Company or by any  Restricted
Subsidiary,  (v) no  Default  or Event of Default  shall  have  occurred  and be
continuing on the date of such proposed Asset Sale and (vi) such Asset Sale will
not materially  adversely affect or materially impair the value of the remaining
Collateral or materially  interfere  with the Trustee's  ability to realize such

                                       32
<PAGE>

value and will not  materially  impair  the  maintenance  and  operation  of the
remaining  Collateral,  as  determined by the Board of Directors of the Company,
which determination shall be set forth in a resolution of the Board of Directors
and described in an Officers' Certificate delivered to the Trustee.

          (b) The Company shall apply,  or cause such  Restricted  Subsidiary to
apply,  the Net  Proceeds  of such  Asset  Sale and any  Insurance  Proceeds  or
Condemnation  Proceeds,  as the case may be, resulting from a Loss Event, within
270 calendar days of  consummation  of such Asset Sale or the collection of such
Insurance  Proceeds  or  Condemnation  Proceeds,  as the  case  may be,  for the
following purposes, individually or in combination:

          (i)  (A)  to  purchase  or  otherwise   invest  in  Related   Business
               Investments  which shall constitute  additional  Collateral under
               the relevant  Security  Documents and which shall be subject to a
               first  priority  Lien in favor of the  Trustee for the benefit of
               the  Holders,  subject  to Liens  permitted  under  the  Security
               Documents  in  respect  of  the  relevant  item  of   Collateral;
               PROVIDED,  that such purchase or Investment  shall be made by the
               Company or such Restricted  Subsidiary,  (B) to purchase Notes in
               open-market  transactions;  PROVIDED,  that the Company  shall be
               deemed to have applied such Net Proceeds,  Insurance  Proceeds or
               Condemnation Proceeds pursuant to this clause (B) in satisfaction
               of the  requirements  of this  covenant in an amount equal to the
               lesser  of (x)  the  purchase  price  paid  in  such  open-market
               transactions  and (y) 100% of the  principal  amount of the Notes
               repurchased;  PROVIDED,  further that the aggregate amount of Net
               Proceeds, Insurance Proceeds or Condemnation Proceeds that may be
               deemed to be applied pursuant to this clause (B) shall not exceed
               US$5,000,000 in the aggregate from the Effective Date, and (C) to
               repay  senior  secured   Indebtedness   of  the  Company  or  its
               Restricted  Subsidiaries  incurred  pursuant  to  clause  (i)  of
               Section 4.9(b); and

          (ii) if and to the  extent  that the  Company  fails to expend any Net
               Proceeds,  Insurance Proceeds or Condemnation  Proceeds remaining
               after application  pursuant to the preceding  subparagraph (b)(i)
               (the "Excess Proceeds  Amount"),  the Company shall make an offer
               to  repurchase  Notes  (an  "Asset  Sale  Offer")  in  an  amount
               (expressed  as an  integral  multiple of  US$1,000)  equal to the
               maximum aggregate principal amount of Notes that may be purchased
               with the Excess Proceeds Amount at a purchase price equal to 100%
               of the principal  amount thereof plus accrued and unpaid interest
               thereon,  if any (the "Net Proceeds Offer Price"), to the date of
               purchase (the "Net Proceeds  Purchase  Date") in accordance  with
               the  procedures  set forth in this Section 4.10.  The Company may
               defer the Asset Sale Offer until the aggregate  unutilized Excess
               Proceeds  Amount equals or exceeds  US$10,000,000  resulting from
               one or more Asset Sales or Loss Events (at which time, the entire
               unutilized  Excess  Proceeds  Amount,  and not just the amount in
               excess of US$10,000,000, shall be applied as required pursuant to
               this paragraph).  All amounts remaining after the consummation of
               any Asset Sale Offer  pursuant  to this  paragraph  shall  remain
               subject to the Lien of the Security  Documents and may be used by
               the  Company  only to  purchase  or  otherwise  invest in Related
               Business   Investments   (which   shall   constitute   additional
               Collateral under the Security  Documents) or to purchase Notes in
               open  market  transactions  up to the maximum set forth in clause
               (i)(B) of this paragraph (b) or to permanently repay Indebtedness
               of the Company or any Guarantor that is not  subordinated  to the
               Notes.

          (c) Each  notice of an Asset Sale Offer shall be mailed by first class
mail to the record  Holders as shown on the register of Holders not less than 30
calendar  days nor more than 60 calendar  days before the Net Proceeds  Purchase
Date, with a copy to the Trustee, and shall comply with the procedures set forth
in this Indenture.  Upon receiving  notice of the Asset Sale Offer,  Holders may
elect  to  tender  their  Notes in whole  or in part in  integral  multiples  of
US$1,000  principal  amount in exchange for cash. To the extent Holders properly
tender  Notes in an  amount  exceeding  the  Excess  Proceeds  Amount,  Notes of
tendering  Holders  will be  purchased  on a PRO RATA  basis  (based on  amounts
tendered).  An Asset Sale Offer  shall  remain  open for a period of 20 Business
Days and until the close of business on the Net Proceeds  Purchase  Date or such
longer  period as may be  required  by law.  Each  notice of an Asset Sale Offer
shall contain all instructions and materials necessary to enable such Holders to
tender  Notes  pursuant  to the Asset  Sale Offer and shall  identify  the Notes
(including CUSIP number) and shall state the following terms: (i) that the Asset

                                       33
<PAGE>

Sale  Offer is being  made  pursuant  to this  Section  4.10 and that all  Notes
tendered will be accepted for payment; PROVIDED,  HOWEVER, that if the aggregate
principal  amount of Notes tendered in an Asset Sale Offer plus accrued interest
at the  expiration of such offer exceeds the aggregate  amount of the Asset Sale
Offer,  the Company  shall  select the Notes to be purchased on a PRO RATA basis
(with such adjustments as may be deemed  appropriate by the Company so that only
Notes in  denominations  of US$1,000 or multiples  thereof shall be  purchased);
(ii) the Net Proceeds Offer Price and the Net Proceeds Purchase Date; (iii) that
any Note not tendered will continue to accrue  interest;  (iv) that,  unless the
Company  defaults in making  payment  therefor,  any Note  accepted  for payment
pursuant to the Asset Sale Offer shall  cease to accrue  interest  after the Net
Proceeds  Purchase  Date;  (v) that  Holders  electing to have a Note  purchased
pursuant to an Asset Sale Offer will be required to surrender the Note, with the
form  entitled  "Option of Holder to Elect  Purchase" on the reverse of the Note
completed,  to the Paying Agent at the address  specified in the notice prior to
the close of  business  on the  third  Business  Day  prior to the Net  Proceeds
Purchase Date;  (vi) that Holders will be entitled to withdraw their election if
the Paying Agent  receives,  not later than five  Business Days prior to the Net
Proceeds  Purchase  Date, a facsimile  transmission  or letter setting forth the
name of the Holder,  the principal  amount of the Notes the Holder delivered for
purchase and a statement  that such Holder is  withdrawing  his election to have
such Note  purchased;  and (vii) that Holders whose Notes are purchased  only in
part will be issued new Notes in a  principal  amount  equal to the  unpurchased
portion of the Notes surrendered; PROVIDED that each Note purchased and each new
Note issued shall be in an original  principal amount of US$1,000 or an integral
multiple thereof.

          On or before 11:00 a.m. on the Net Proceeds Purchase Date, the Company
shall (i) accept for payment Notes or portions thereof tendered  pursuant to the
Asset Sale Offer which are to be  purchased  in  accordance  with clause (ii) of
paragraph  (b) above,  (ii)  deposit  with the Paying  Agent U.S.  Legal  Tender
sufficient to pay the Net Proceeds  Offer Price of all Notes to be purchased and
(iii)  deliver to the  Trustee  Notes so  accepted  together  with an  Officers'
Certificate  stating  the  Notes or  portions  thereof  being  purchased  by the
Company.  The  Paying  Agent  shall  promptly  mail to the  Holders  of Notes so
accepted  payment  in an  amount  equal to the Net  Proceeds  Offer  Price.  For
purposes of this Section 4.10, the Trustee shall act as the Paying Agent.

          If an offer is made to repurchase  the Notes pursuant to an Asset Sale
Offer,  the Company will comply with the  requirements  of Section  14(e) of the
Exchange Act, if  applicable,  the  provisions of Rule 13e-4 and Rule 14e-1,  if
applicable,  and any other  tender  offer rules under the  Exchange Act or other
relevant United States Federal and state securities  legislation  which may then
be  applicable  and will  file  Schedule  13E-4 or any other  schedule  required
thereunder  in  connection  with any  offer by the  Company  to  purchase  Notes
pursuant to an Asset Sale  Offer.  Notes  repurchased  pursuant to an Asset Sale
Offer shall be  delivered  to the Trustee for  cancellation  pursuant to Section
2.12.

          (d) All Net Proceeds,  Insurance  Proceeds and  Condemnation  Proceeds
from Loss Events and  non-cash  consideration  from Asset Sales,  including  all
Excess  Proceeds  Amounts,  shall be deposited in the Collateral  Account and be
subject to the perfected  first priority Lien in favor of the Collateral  Agent,
for the benefit of the  Trustee  and the Holders of the Notes,  subject to Liens
permitted  under the  Security  Documents  in  respect of the  relevant  item of
Collateral.  To the extent not applied as set forth above,  such Excess Proceeds
Amounts shall remain on deposit in the  Collateral  Account in  accordance  with
this Indenture and the Security Documents.  Excess Proceeds Amounts so deposited
in the Collateral  Account may be withdrawn from the Collateral Account pursuant
to Section 4.10(b).

          (e) Notwithstanding the foregoing,  any disposition of Collateral that
is governed under and complies with Article 5 shall not be deemed to be an Asset
Sale,  except that in the event of the  transfer of  substantially  all (but not
all) of the  Property  of the  Company  and its  Subsidiaries  to a Person  in a
transaction permitted under Article 5, the successor corporation shall be deemed
to have sold the Collateral  not so  transferred  for purposes of this covenant,
and shall  comply with the  provisions  of this  covenant  with  respect to such
deemed sale as if it were an Asset Sale.  In addition,  the Fair Market Value of
such  Property  of the  Company or its  Subsidiaries  deemed to be sold shall be
deemed to be Net Proceeds for purposes of this Section 4.10.

dispose of any of its  properties  or assets to, or  purchase  any  property  or
assets  from,  or  enter  into  or  make  or  amend  any  contract,   agreement,
understanding,  loan,  advance or  guarantee  with,  or for the  benefit of, any
Affiliate (other than the Company or a Wholly Owned Restricted Subsidiary) (each
of the  foregoing,  an  "Affiliate  Transaction"),  unless  (i)  such  Affiliate
Transaction  is on  terms  that  are no less  favorable  to the  Company  or the
relevant  Restricted  Subsidiary  than those that would have been  obtained in a
comparable transaction with an unrelated Person and (ii) the Company delivers to
the Trustee (a) with respect to any Affiliate  Transaction  or series of related
Affiliate   Transactions   after  the   Effective   Date   involving   aggregate
consideration  in excess of US$2,000,000  (or the equivalent  thereof at time of
determination),  a resolution described in an Officers' Certificate,  certifying
that  such  Affiliate  Transaction  complies  with  clause  (i)  above  and such
Affiliate  Transaction  has been  approved  by a majority  of the  disinterested
members of the Board of  Directors  of the Company  and (b) with  respect to any
Affiliate  Transaction  or series of related  Affiliate  Transactions  after the
Effective Date involving  aggregate  consideration in excess of US$5,000,000 (or
the equivalent thereof at time of determination),  an opinion as to the fairness
to the Holders of the Notes of such Affiliate Transaction from a financial point
of view  issued  by an  accounting,  appraisal  or  investment  banking  firm of
recognized  national standing in Brazil;  PROVIDED that (1) any transaction with
an  officer  or  director  of the  Company  or  any  Restricted  Subsidiary  (in
connection  with such  person's  compensation,  employee  benefit  or  severance
arrangements) entered into by the Company or any of its Restricted  Subsidiaries
in the ordinary  course of business and customary in the industry of the Company
or such Restricted Subsidiary, (2) transactions between or among the Company and
its Restricted  Subsidiaries,  (3) the Programming Agreement,  (4) any Operating

          The  Company  will  not,  and will not  permit  any of its  Restricted
Subsidiaries to, directly or indirectly, create, incur, affirm, assume or suffer
to exist any Lien of any kind on any  property  or asset now owned or  hereafter
acquired,  or any income or profits  therefrom  or assign or convey any right to
receive  income  therefrom,   except  for  Liens  securing  any  senior  secured
Indebtedness incurred pursuant to clause (i) of Section 4.9(b), PROVIDED that no
such Lien shall be senior to the Liens on the Collateral  granted to the Trustee
under the Security  Documents;  PROVIDED,  HOWEVER,  that the foregoing will not
prohibit or restrict Permitted Liens.

SECTION 4.13.  GUARANTORS.

          (a) If at any time on or after  the  Effective  Date,  and at any time
that any of the Obligations  remain  outstanding,  the Company or any Restricted
Subsidiary establishes or creates a Restricted Subsidiary and either the Company
elects  to  have  such   Restricted   Subsidiary   become  a  Guarantor  or  the
establishment  or creation of such Restricted  Subsidiary  would be a Restricted
Investment  unless it becomes a Guarantor,  then the Company (or the  Restricted
Subsidiary  directly owning Capital Stock of such other  Restricted  Subsidiary)
shall (i) cause each such  Restricted  Subsidiary  to execute and deliver to the
Trustee  a  supplemental  indenture  pursuant  to  which  each  such  Restricted
Subsidiary  shall  guarantee  the  Obligations  of the Company on a senior basis
together  with an opinion of counsel  (which  counsel  may be an employee of the
Company) to the effect that the  supplemental  indenture  has been duly executed
and  delivered by each such  Restricted  Subsidiary  and is in compliance in all
material  respects with the terms of this Indenture,  (ii) cause such Restricted
Subsidiary  to  execute  and  deliver  to the  Collateral  Agent  such  Security

forth in the Master Security Agreement,  deliver to the Collateral Agent for the

          (b) The Company will not permit any  Restricted  Subsidiary  that is a
Guarantor  to issue or sell any  Capital  Stock  other than to the  Company or a
Restricted  Subsidiary,  (i) if such issuance or sale could adversely  affect or
impair the  legality  or  enforceability  of, or the  ability of the  Trustee to
realize upon, the Guarantee  granted by such  Restricted  Subsidiary  hereunder;
(ii) if such issuance or sale would result in any Person or Persons  (other than
the  Company or a  Restricted  Subsidiary),  directly or  indirectly,  owning or
controlling  15% or more of the Capital Stock of any Restricted  Subsidiary that
is a  Guarantor;  PROVIDED,  HOWEVER,  that  any sale of 100% of the  shares  of
Capital  Stock of any  Restricted  Subsidiary  that is a  Guarantor  effected in
accordance with Section 4.10 or Section 5.1 shall be permitted; and (iii) unless
such  Restricted  Subsidiary  receives  the Fair Market  Value for such  Capital
Stock.

SECTION 4.14.  OFFER TO REPURCHASE UPON CHANGE OF CONTROL.

          (a) Upon the occurrence of a Change of Control,  the Company will make
an offer (a "Change of Control  Offer") to repurchase  all or any part (equal to
US$1,000 or an integral  multiple  thereof) of each  Holder's  Notes at an offer
price in cash equal to 101% of the  aggregate  principal  amount  thereof,  plus
accrued and unpaid  interest,  if any,  thereon to the date of  repurchase  (the
"Change of Control  Payment").  Within 30 calendar days  following any Change of
Control,  the  Company  will  mail  a  notice  to  each  Holder  describing  the
transaction  that  constitutes  the Change of Control and offering to repurchase
Notes  pursuant to the  procedures  required by this  Indenture and described in

the Exchange Act and any other securities laws and regulations thereunder to the
extent  such  laws  and  regulations  are  applicable  in  connection  with  the
repurchase  of the  Notes as a result  of a Change  of  Control.  The  Change of
Control provisions  described in this Section 4.14 will be applicable whether or
not any other provisions of this Indenture are applicable.

          (b) Notice of a Change of Control Offer will be mailed by the Company,
with a copy to the Trustee,  or, at the Company's option, by the Trustee (at the
Company's expense) not more than 30 calendar days after the Change of Control to
each Holder of the Notes at such Holder's last registered  address  appearing in
the Register.  In such notice,  the Company will describe the  transaction  that
constitutes the Change of Control and offer to repurchase  Notes pursuant to the
procedures  established  by this Section 4.14 and described in such notice.  The
notice will contain all instructions  and materials  necessary to enable Holders

nor later than 90  calendar  days after the  Change of Control  (the  "Change of
Control Payment Date"); (iii) that any Note not tendered will continue to accrue
interest; (iv) that, unless the Company defaults in the payment of the Change of
Control  Payment,  all Notes  accepted  for  payment  pursuant  to the Change of
Control Offer will cease to accrue  interest after the Change of Control Payment
Date; (v) that Holders electing to have any Notes purchased pursuant to a Change
of Control  Offer will be required to deliver the Notes,  with the form entitled
"Option of Holder to Elect Purchase" on the reverse of the Notes  completed,  or

the Company),  or the Paying Agent at the address  specified in the notice prior
to the close of  business  on the third  Business  Day  preceding  the Change of
Control  Payment  Date;  (vi) that  Holders  will be entitled to withdraw  their
election if the Company, the Depository or the Paying Agent, as the case may be,
receives,  not  later  than the close of  business  on the  third  Business  Day
preceding the Change of Control Payment Date, a telegram, facsimile transmission
or letter  setting forth the name of the Holder,  the principal  amount of Notes
delivered  for purchase,  and a statement  that such Holder is  withdrawing  his
election to have the Notes  purchased;  and (vii) that  Holders  whose Notes are
being purchased only in part will be issued new Notes equal in principal  amount
to  the  unpurchased  portion  of  the  Notes  surrendered  (or  transferred  by
book-entry  transfer),  which  unpurchased  portion  must be  equal  to at least
US$1,000 in principal amount or an integral multiple thereof.

                                       36
<PAGE>

          (c) On the Change of Control Payment Date, the Company will (i) accept
for payment Notes or portions thereof validly tendered pursuant to the Change of
Control Offer, (ii) deposit with the Paying Agent money in immediately available
funds  sufficient to pay the purchase price of all Notes or portions  thereof so
accepted,  and (iii) deliver to the Trustee  Notes so accepted  together with an
Officers' Certificate stating the Notes or portions thereof accepted for payment
by the Company.  If the Company  complies with its  obligations set forth in the
immediately preceding sentence, whether or not a Default or Event of Default has
occurred and is  continuing on the Change of Control  Payment  Date,  the Paying
Agent will as promptly as practicable mail or deliver to each Holder of Notes so
accepted  payment in an amount equal to the purchase price, and the Company will
execute and the Trustee will as promptly as practicable authenticate and mail or
deliver to such Holder a new Note equal in principal  amount to any  unpurchased
portion of the Note  surrendered;  PROVIDED that each such new Note will be in a
principal amount of US$1,000 or an integral multiple  thereof.  Any Notes not so
accepted will be as promptly as  practicable  mailed or delivered by the Trustee
to the Holders  thereof.  The Company will publicly  announce the results of the
Change of Control  Offer on or as  promptly as  practicable  after the Change of
Control Payment Date. For purposes of this Section 4.14, the Trustee will act as
the Paying Agent.

          (d) Prior to complying with the other provisions of this Section 4.14,

consents,  if any, under all agreements  governing  outstanding  Indebtedness to
permit the repurchase of Notes required by this Section 4.14.

          (e) The Company will not be required to make a Change of Control Offer
upon a Change of Control if a third party  makes the Change of Control  Offer in
the manner,  at the times and otherwise in compliance with the  requirements set
forth in this  Indenture  applicable  to a Change of  Control  Offer made by the
Company and purchases all Notes  validly  tendered and not withdrawn  under such
Change of Control Offer.

SECTION 4.15.  CORPORATE EXISTENCE.

          Except  as  otherwise  permitted  pursuant  to the terms  hereof,  the
Company will do or cause to be done all things necessary to preserve and keep in
full  force  and  effect  (i)  its  corporate  existence,   and  the  corporate,

accordance with their  respective  organizational  documents (as the same may be
amended  from  time  to  time),  and  (ii)  the  material  rights  (charter  and
statutory),  licenses and  franchises of the Company and each of its  Restricted
Subsidiaries;  PROVIDED,  HOWEVER,  that the  Company  will not be  required  to
preserve  any such right,  license or  franchise  belonging  to it or any of its
Restricted Subsidiaries, or the corporate, partnership or other existence of any
of its  Restricted  Subsidiaries,  if the  Board  of  Directors  of the  Company
determines that the  preservation  thereof is no longer desirable in the conduct
of the business of the Company and its Subsidiaries,  taken as a whole, and that
the loss thereof would not  reasonably be expected to be adverse in any material
respect to the Holders of the Notes.

SECTION 4.16.  LIMITATION ON ASSET SWAPS.

          The  Company  will  not,  and will not  permit  any of its  Restricted
Subsidiaries  to,  in one or a  series  of  related  transactions,  directly  or
indirectly, engage in any Asset Swaps, unless:

          (i)  at the time of  entering  into the  agreement  to swap assets and
               immediately  after giving  effect to the proposed  Asset Swap, no
               Default or Event of Default shall have occurred and be continuing
               or would occur as a consequence thereof;

          (ii) the respective  Fair Market Values of the assets being  purchased
               and sold by the Company or any of its Restricted Subsidiaries are
               substantially the same at the time of entering into the agreement
               to swap assets; and

          (iii)at the time of the  consummation  of the proposed Asset Swap, the
               percentage  of any decline in the Fair Market  Value of the asset
               or  assets  being  acquired  by the  Company  and its  Restricted
               Subsidiaries   will  not  be   significantly   greater  than  the
               percentage  of any decline in the Fair Market Value of the assets
               being disposed of by the Company or its Restricted  Subsidiaries,
               calculated from the time the agreement to swap assets was entered
               into.

<PAGE>

          The  Company  will  not,  and will not  permit  any of its  Restricted
Subsidiaries  to, enter into any sale and leaseback  transaction;  PROVIDED that
the Company may enter into a sale and leaseback transaction if the Company could
have (i)  incurred  Indebtedness  in an amount  equal to the  Attributable  Debt
relating  to such sale and  leaseback  transaction  and (ii)  incurred a Lien to
secure such Indebtedness pursuant to Section 4.12.

SECTION 4.18.  MAINTENANCE OF BUSINESS, PROPERTIES AND INSURANCE.

          (a) The Company  will not,  and will not permit any of its  Restricted
Subsidiaries  to,  engage  in any  business  other  than the  Telecommunications
Business and such  business  activities as are  incidental  or directly  related
thereto.

          (b)  The  Company  shall,  and  shall  cause  each  of the  Restricted
Subsidiaries  to,  maintain its material  properties  in good working  order and
condition (subject to ordinary wear and tear) and make all reasonably  necessary
repairs, renewals, replacements, additions, betterments and improvements thereto
to actively conduct and carry on its business;  PROVIDED,  HOWEVER, that nothing
in  this  Section  4.18  shall  prevent  the  Company  or any of the  Restricted
Subsidiaries  from  discontinuing  the operation and  maintenance  of any of its
properties,  if such  discontinuance is, in the good faith judgment of the Board
of Directors of the Company or such Restricted  Subsidiary,  as the case may be,
desirable   in  the  conduct  of  their   respective   businesses   and  is  not
disadvantageous  in any  material  respect to the Holders as  determined  by the
Board of Directors of the Company.

          (c) The Company shall provide or cause to be provided,  for itself and
each  of  its  Restricted   Subsidiaries,   insurance   (including   appropriate
self-insurance)  against  loss or damage of the kinds  that,  in the good  faith
judgment of the Board of Directors of the Company,  are adequate and appropriate
for the conduct of the business of the Company and its  Restricted  Subsidiaries
in a prudent manner, with reputable insurers or with the government of Brazil or
an agency or instrumentality  thereof,  in such amounts,  with such deductibles,
and by such  methods as shall be  customary,  in the good faith  judgment of the
Board of  Directors of the Company,  for  companies in Brazil and for  companies
similarly situated in the industry;  PROVIDED,  HOWEVER,  that the Company shall
provide  or  cause  to be  provided,  for  itself  and  each  of its  Restricted
Subsidiaries,   directors  and  officers  liability   insurance  with  reputable
insurers.

          (d)  The  Company  shall,  and  shall  cause  each  of its  Restricted
Subsidiaries to comply with all Applicable  Laws of any Authority  except to the
extent that noncompliance  could not, singly or in the aggregate,  reasonably be
expected  to  have  a  material  adverse  effect  on the  business,  properties,
condition (financial or otherwise) or prospects of the Company or its Restricted
Subsidiaries, as determined by the Board of Directors of the Company.

          (e) The Company will not permit the  Operating  Agreement to terminate
or be  modified  in any way  which  prevents  the  Company  and  the  Restricted
Subsidiaries  from  operating pay television  systems  relating to the Company's
authorizations, licenses or Permits.

SECTION 4.19.  IMPAIRMENT OF SECURITY INTEREST.

          Neither the Company nor any of its  Subsidiaries  will take or omit to
take any action which action or omission  could  reasonably  be expected to have
the result of  materially  and adversely  affecting or materially  impairing the
security  interests in favor of the Collateral  Agent,  on behalf of the Trustee
and the Holders, with respect to the Collateral.  Neither the Company nor any of
its  Subsidiaries  will enter into any agreement or instrument that by its terms
requires the Net Proceeds  received from any sale of Collateral to be applied to
repay,  redeem,  defease or otherwise  acquire or retire any Indebtedness of any
Person prior to the repayment in full of the Notes,  other than the Indebtedness
permitted  under  Section  4.9(b)(i) to the extent such  repayment,  redemption,
defeasance, acquisition or retirement is permitted under Section 4.10(b).

SECTION 4.20.  PAYMENT OF ADDITIONAL AMOUNTS.

                                       38
<PAGE>

          All  payments by the Company in respect of the Notes or any  Guarantor
in respect  of its  Guarantee  of the Notes  shall be made free and clear of and
without  withholding  or  deduction  for or on account of any  present or future
taxes,  duties,  assessments or other  governmental  charges of whatever nature,
including penalties, interest and any other liabilities related thereto, imposed
or  levied  by or on  behalf  of  Brazil  or any  relevant  jurisdiction  or any
political  subdivision  or  authority  thereof  or therein  having  power to tax
("Taxes").  In the event that the Company or any Guarantor,  as the case may be,
is required to make any  withholding or deduction for or on account of any Taxes
from any payment made under or with respect to the Notes,  or its Guarantee,  as
the case may be, the Company or any Guarantor, as the case may be, will pay such
additional  amounts  ("Additional  Amounts") as may be necessary so that the net
amount  received  by each  Holder  (including  Additional  Amounts)  after  such
withholding  or deduction will not be less than the amount the Holder would have
received  had such  Taxes  not been  withheld  or  deducted;  PROVIDED,  that no
Additional  Amounts will be payable to a Holder (an "Excluded  Holder") (i) with
which the Company or any  Guarantor,  as the case may be, does not deal at arm's
length at the time of making such  payment,  (ii) which is subject to such Taxes
by reason of its being  connected  with Brazil or any political  subdivision  or
authority thereof otherwise than by the mere holding of the Notes or the receipt
of payments  thereunder,  (iii) which presents any Note for payment of principal
more than 60  calendar  days  after  the later of (x) the date on which  payment
first became due and (y) if the full amount payable has not been received by the
Trustee on or prior to such due date, the date on which, the full amount payable
having  been so  received,  notice to that  effect  shall have been given to the
Holders by the  Company,  except to the extent  that the Holder  would have been
entitled to such  Additional  Amounts on presenting such Note for payment on the
last day of the applicable  60-day period,  (iv) which failed to duly and timely
comply with a timely request of the Company to provide information, documents or
other evidence concerning the Holder's  nationality,  residence,  entitlement to
treaty benefits, identity or connection with Brazil or any political subdivision
or authority  thereof,  if and to the extent that due and timely compliance with
such request would have reduced or eliminated  any Taxes as to which  Additional
Amounts  would have  otherwise  been  payable to such Holder but for this clause
(iv), (v) on account of any estate, inheritance,  gift, sale, transfer, personal
property or other similar Tax, (vi) which is a fiduciary, a partnership,  or not
the  beneficial  owner of any  payment on a Note,  if and to the extent that any
beneficiary or settlor of such fiduciary,  any partner in such  partnership,  or
the  beneficial  owner of such  payment (as the case may be) would not have been
entitled to receive  Additional  Amounts  with  respect to such  payment if such
beneficiary,  settlor,  partner or beneficial  owner had been the Holder of such
Note or (vii) any combination of the foregoing numbered clauses of this proviso.

          The Company or any  Guarantor,  as the case may be, will also (i) make
such  withholding  or deduction as required by applicable law and (ii) remit the
full amount  deducted or withheld to the relevant  authority in accordance  with
applicable law. The Company or any Guarantor,  as the case may be, will furnish,
within 60 calendar  days after the date the payment of any Taxes is due pursuant
to applicable  law, to the Trustee copies of tax receipts  evidencing  that such
payment has been made by the Company or such  Guarantor,  as the case may be, in
such form as provided in the normal course by the taxing authority imposing such
Taxes and as is reasonably  available to the Company or such  Guarantor,  as the
case may be. The Trustee  shall make such  evidence  available to the Holders of
Notes upon written request.

          If the  Company  or any  Guarantor,  as the case may be,  has paid any
Additional  Amounts to any Holder or, if different,  the beneficial owners of an
interest  in any Note,  and such  person is entitled to a refund of the Taxes to
which such  Additional  Amounts are  attributable  from any  competent  taxation
authority or other  governmental  body, then (a) such person shall so notify the
Company or such  Guarantor  as promptly as  practicable  after  learning of such
entitlement, and as soon as practicable but in any event within 30 calendar days
after receiving a written  request  therefor from the Company or such Guarantor,
as the case may be,  comply  with any  administrative  procedure  to obtain such
refund and (b) upon receipt of such refund, promptly pay over such refund to the
Company or such Guarantor, as the case may be. If Additional Amounts are paid to
a Holder, or, if different, the beneficial owner of an interest in any Note, and
it is  subsequently  determined  that  such  Person  was  not  entitled  to such
Additional  Amounts,  then such Person shall  promptly  refund to the Company or
such Guarantor,  as the case may be, the amount of all such  Additional  Amounts
previously paid to such Person.

          The Company will indemnify and hold harmless each Holder of Notes that
are outstanding on the date that withholding or deduction was required  pursuant
to  applicable  law (other than an Excluded  Holder)  and upon  written  request
reimburse  each such Holder for the amount of (i) any taxes so levied or imposed
and paid by such  Holder as a result of payments  made under or with  respect to
the  Notes  or  any Guarantee, as the case may be, (ii) any liability (including

                                       39
<PAGE>

penalties, interest and expenses) arising therefrom or with respect thereto, and
(iii) any taxes  imposed with respect to any  reimbursement  under clause (i) or
(ii) above.

          Whenever in this Indenture there is mentioned, in any context, (a) the
payment of principal (and premium,  if any),  (b) purchase  prices in connection
with a repurchase of Notes,  (c) interest or (d) any other amount  payable on or
with  respect  to any of the  Notes,  such  mention  shall be deemed to  include
mention of the payment of Additional Amounts provided for in this section to the
extent that, in such context,  Additional  Amounts are, were or would be payable
in respect thereof.

Subsidiaries (or the payment of which is guaranteed by the Company or any of its
Restricted  Subsidiaries),  whether such Indebtedness or Guarantee now exists or
is created after the Effective Date, which default (i) is caused by a failure to
pay principal of or premium, if any, or interest on such Indebtedness  following
the expiration of the grace period provided in such  Indebtedness on the date of
such default (a "Payment  Default") or (ii) results in the  acceleration of such
Indebtedness  prior to its express  maturity  and, in each case,  the  principal

stayed for a period of 60 calendar  days after such  judgments  become final and
non-appealable;

          (h) the Company or any Restricted  Subsidiary of the Company  pursuant
to or within the meaning of any  Bankruptcy  Law: (i) commences a voluntary case
or  proceeding,  (ii) consents to the entry of an order for relief against it in
an  involuntary  case or  proceeding,  (iii)  consents to the  appointment  of a
Custodian of it or for all or  substantially  all of its property,  (iv) makes a
general  assignment for the benefit of its creditors,  (v) admits in writing its
inability  to pay its  debts  generally  as they  become  due or (vi)  takes any
comparable action under any foreign laws relating to insolvency;

                                       42

          (i) a court of competent  jurisdiction enters an order or decree under
any  Bankruptcy  Law  that:  (i)  is  for  relief  against  the  Company  or any
Significant Subsidiary of the Company in an involuntary case or proceeding, (ii)
appoints a Custodian of the Company or any Significant Subsidiary of the Company
or for all or substantially  all of its respective  properties,  or (iii) orders
the liquidation of the Company or any Significant  Subsidiary of the Company, or
any similar relief is granted under any foreign laws, and in each case the order
or decree remains unstayed and in effect for 60 calendar days;

          (j) (a) a default in the  observance or performance of any covenant or
agreement  contained in any Security  Document  which  default  continues for 20
calendar  days  after  notice has been  given to the  Company by the  Collateral
Agent,  the  Trustee or the holders of at least 25% in  principal  amount of the
outstanding Notes, or (b) for any reason other than the satisfaction in full and
discharge of all  obligations  secured  thereby or any action or inaction of the
Collateral  Agent,  the Trustee or the  Holders  after  receiving  notice of the
requirement  to take  any such  action  from the  Company,  any of the  Security
Documents  ceases to be in full force and effect (other than in accordance  with
its  respective  terms),  or any of the  Security  Documents  ceases to give the
Collateral  Agent the Liens,  rights,  powers  and  privileges  purported  to be
created  thereby,  or any Security  Document is declared  null and void,  or the
Company or any of its  Restricted  Subsidiaries  denies  any of its  obligations
under any  Security  Document,  in each  case with  respect  to  Collateral  the
aggregate value of which is in excess of US$100,000,  or the Collateral  becomes
subject to one or more Liens other than  Permitted  Liens  securing  one or more
obligations in excess of US$100,000 in the aggregate; or

          (k) any  Guarantee  is declared  null and void or ceases to be in full
force and effect  (except as permitted  under this  Indenture)  or any Guarantor
shall deny or disaffirm its obligations under its Guarantee.

          Notwithstanding  the  foregoing,  if an Event of Default  specified in
clause  (f) above  occurs  and is  continuing,  such  Event of  Default  and all
consequences  thereof  (including,   without  limitation,  any  acceleration  or
resulting  payment  default) will be annulled and rescinded,  automatically  and
without  any  action by the  Trustee or the  Holders  of the  Notes,  if (i) the
Indebtedness  that is the subject of such Event of Default has been  repaid,  or
(ii) the default  relating to such  Indebtedness is waived or cured (and if such
Indebtedness has been accelerated, when the holders thereof have rescinded their
declaration of acceleration in respect of such Indebtedness).

          In the case of any Event of Default occurring by reason of any willful
action (or  inaction)  taken (or not taken) by or on behalf of the Company  with
the intention of avoiding payment of the premium that the Company would have had
to pay if the  Company  then had  elected  to redeem the Notes  pursuant  to the
optional  redemption  provisions of this Indenture,  an equivalent  premium will
also become and be  immediately  due and payable to the extent  permitted by law
upon the acceleration of the Notes.

SECTION 6.2.  ACCELERATION.

          If any Event of Default  (other than an Event of Default  specified in
Section  6.1 (h) or (i))  occurs  and is  continuing,  then the  Trustee  or the
Holders of at least 25% in  principal  amount of the then  outstanding  Notes by
written  notice to the Company and the Trustee may declare the unpaid  principal
of,  and  any  accrued  interest  on,  all  the  Notes  to be  due  and  payable
immediately.  If any Event of Default  specified in Section 6.1(h) or (i) hereof
occurs with respect to the Company, any Significant Subsidiary of the Company or
any group of Restricted Subsidiaries of the Company that, taken together,  would
constitute a Significant  Subsidiary of the Company,  all outstanding  principal
and  interest  on the Notes will be  immediately  due and  payable  without  any
declaration  or other act on the part of the Trustee or any Holder.  The Holders
of a majority  in  principal  amount of the Notes then  outstanding,  by written
notice to the Trustee and to the Company, may rescind an acceleration (except an
acceleration  due to a default  in payment  of the  principal  of, or premium or
interest on, any of the Notes) if the  rescission  would not  conflict  with any
judgment or decree and if all existing Events of Default  (except  nonpayment of
principal,  premium,  interest  that  have  become  due  solely  because  of the
acceleration) have been cured or waived.

SECTION 6.3.  OTHER REMEDIES.

                                       43
<PAGE>

          Subject  to  Section  6.2,  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 any payment due on the Notes or to enforce the  performance
of any provision of the Notes, this Indenture or the Security Documents.

          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.  A delay or
omission  by the  Trustee  or any  Holder of a Note in  exercising  any right or
remedy  accruing upon an Event of Default will not impair the right or remedy or
constitute a waiver of or acquiescence in the Event of Default. All remedies are
cumulative to the extent permitted by law.

SECTION 6.4.  WAIVER OF PAST DEFAULTS.

          Subject to Section 9.2,  Holders of a majority in aggregate  principal
amount of the then outstanding  Notes by notice to the Trustee may, on behalf of
the Holders of all of the Notes,  waive an existing  Default or Event of Default
and its consequences  hereunder  (including without limitation  acceleration and
its consequences,  including any related payment default that resulted from such
acceleration)  except a continuing Default or Event of Default in the payment of
the  principal  of, or premium or interest on the Notes.  Upon any such  waiver,
such Default  will cease to exist,  and any Event of Default  arising  therefrom
will be deemed to have been cured for every  purpose of this  Indenture;  but no
such waiver will extend to any  subsequent  or other Default or impair any right
consequent thereon.

SECTION 6.5.  CONTROL BY MAJORITY.

          The Holders of a majority in  aggregate  principal  amount of the then
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 it.  However,  the Trustee may refuse to follow any direction
that conflicts with law or this Indenture or that the Trustee  determines may be
unduly  prejudicial to the rights of another Holder or that involves the Trustee
in personal  liability.  The Trustee may take any other action  deemed proper by
the Trustee that is not inconsistent with such direction.

SECTION 6.6.  LIMITATION ON SUITS.

          Subject to the  provisions of Section 6.7 hereof,  no Holder of a Note
may pursue any remedy with respect to this  Indenture  or the Notes  (including,
without  limitation,  the institution of any proceeding,  judicial or otherwise,
with respect to the Notes or this Indenture or for the appointment of a receiver
or trustee for the Company and/or any of its Subsidiaries) unless:

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

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

          (c) such  Holders  have  offered to provide to the  Trustee  indemnity
reasonably satisfactory to the Trustee against any loss, liability or expense;

          (d) the Trustee has not complied  with the request  within 60 calendar
days after receipt of the request and the offer of indemnity; and

          (e) during such 60-day period,  the Holders of a majority in aggregate
principal  amount of the Notes  then  outstanding  have not given the  Trustee a
direction  which,  in the  opinion  of the  Trustee,  is  inconsistent  with the
request.

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

                                       44

SECTION 6.7.  RIGHTS OF HOLDERS OF NOTES TO RECEIVE PAYMENT.

          The right of any Holder of a Note to receive  payment of principal of,
and premium,  if any, or interest on, such Note, on or after the  respective due
dates  expressed  in such  Note  (including  in the  case of a  redemption,  the
applicable redemption price on the applicable redemption date), or to bring suit
for the enforcement of any such payment on or after such respective  dates, will
not be impaired or affected without the consent of such Holder.

SECTION 6.8.  COLLECTION SUIT BY TRUSTEE.

          If an Event of Default  specified in Section  6.1(a) or (b) occurs and
is continuing, the Trustee is authorized to recover judgment in its own name and
as trustee of an express trust against the Company for principal of, premium, if
any, and interest  on, the Notes and interest on overdue  principal  and, to the
extent lawful,  interest, and such further amount as will 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 to the Trustee under Section 7.7.

SECTION 6.9.  TRUSTEE MAY FILE PROOFS OF CLAIM.

          The  Trustee  is  authorized  to file  such  proofs of claim and other
papers or documents as may be necessary or advisable in order to have the claims
of the Trustee (including any claim for the reasonable  compensation,  expenses,
disbursements  and  advances of the  Trustee,  its agents and  counsel)  and the
Holders of the Notes allowed in any judicial proceedings relative to the Company
(or any other obligor upon the Notes), its creditors or its property and will be
entitled and  empowered to collect,  receive and  distribute  any money or other
property payable or deliverable on any such claims and any custodian in any such
judicial proceeding is hereby authorized by each Holder to make such payments to
the Trustee,  and in the event that the Trustee  shall  consent to the making of
such payments  directly to the Holders,  to pay to the Trustee any amount due to
it for the reasonable compensation,  expenses, disbursements and advances of the
Trustee,  its agents and counsel,  and any other  amounts due the Trustee  under
Section  7.7  hereof.  To the extent  that the  payment  of any such  reasonable
compensation,  expenses,  disbursements and advances of the Trustee,  its agents
and counsel,  and any other amounts due the Trustee under Section 7.7 hereof out
of the estate in any such proceeding, shall be denied for any reason, payment of
the same  will be  secured  by a Lien on,  and will be paid out of,  any and all
distributions,  dividends,  money,  securities  and  other  properties  that the
Holders may be entitled to receive in such proceeding  whether in liquidation or
under any plan of  reorganization  or arrangement  or otherwise.  Nothing herein
contained  will be deemed to authorize the Trustee to authorize or consent to or
accept or adopt on behalf of any Holder any plan of reorganization, arrangement,
adjustment or composition affecting the Notes or the rights of any Holder, or to
authorize  the Trustee to vote in respect of the claim of any Holder in any such
proceeding.

SECTION 6.10.  PRIORITIES.

          If the Trustee  collects any money pursuant to this Article 6, it will
pay out the money in the following order:

          First: to the Trustee,  its agents and attorneys for amounts due under
Section  7.7  hereof,  including  payment  of  all  compensation,   expense  and
liabilities  incurred,  and all advances  made, by the Trustee and the costs and
expenses of collection;

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

          Third:  the  remainder  to the  Company or to such party as a court of
competent jurisdiction may direct.

                                       45
<PAGE>

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

SECTION 6.11.  UNDERTAKING FOR COSTS.

          In any suit for the  enforcement  of any  right or remedy  under  this
Indenture  or in any suit against the Trustee for any action taken or omitted by
it as a Trustee,  each party to this  Indenture  agrees,  and each Holder by its
acceptance  of its Notes  will be deemed to have  agreed,  that any court in its
discretion  may  require  the  filing  by any party  litigant  in the suit of an
undertaking  to pay the costs of the suit,  and the court in its  discretion may
assess reasonable costs, including reasonable attorneys' fees, against any party
litigant  in the suit,  having  due  regard to the  merits and good faith of the
claims or defenses made by the party litigant.  This Section does not apply to a
suit by the  Trustee,  a suit by a Holder  of a Note  pursuant  to  Section  6.7
hereof,  or a suit by Holders of more than 10% in  principal  amount of the then
outstanding Notes.

                                    ARTICLE 7
                                     TRUSTEE

SECTION 7.1.  DUTIES OF TRUSTEE.

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

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

              (i)   the  Trustee  will not be liable  hereunder  except for such
                    duties of the Trustee which will be determined solely by the
                    express  provisions  of this  Indenture and the Trustee need
                    perform only those duties that are specifically set forth in
                    this  Indenture and no others,  and no implied  covenants or
                    obligations  will be read into this  Indenture  against  the
                    Trustee; and

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

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

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

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

              (iii) the Trustee will not be liable with respect to any action it
                    takes or omits to take in good  faith in  accordance  with a
                    direction received by it pursuant to Section 6.5 hereof.

          (d) Whether or not therein  expressly so provided,  every provision of
this  Indenture  that in any way relates to the Trustee is subject to paragraphs
(a), (b) and (c) of this Section 7.1.

          (e) No provision of this  Indenture will require the Trustee to expend
or risk its own funds or incur any liability  whatsoever in the  performance  of
any of its duties  hereunder  or in the  exercise of any of its rights or powers

                                       46
<PAGE>

hereunder. The Trustee will be under no obligation to exercise any of its 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 and
indemnity  satisfactory to the Trustee in its sole subjective  discretion (which
discretion  will be  exercised  in good faith)  against the costs,  expenses and
liabilities  that might be incurred  by it in  compliance  with such  request or
direction.

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

          (g) In the  event  the  Company  incurs  senior  secured  Indebtedness
pursuant to clause (i) of Section  4.9(b),  the Trustee  shall,  and the Holders
shall be deemed to have  authorized  the  Trustee  to,  enter  into  appropriate
intercreditor  agreements  providing for the ratable  sharing of the  Collateral
between  the  holders of senior  secured  Indebtedness  and the  Trustee for the
benefit  of  the  Holders  of the  Notes  and  otherwise  giving  effect  to the
provisions of clause (i) of Section  4.9(b).  For this purpose,  the Trustee may
consult with counsel and rely on Opinions of Counsel and Officers' Certificates.

SECTION 7.2.  RIGHTS OF TRUSTEE.

          (a) Subject to Section 7.1, the Trustee may conclusively rely upon any
document  believed by it to be genuine and to have been signed or  presented  by
the proper Person. The Trustee need not investigate any fact or matter stated in
the document.

          (b) Before the Trustee acts or refrains  from  acting,  it may consult
with  counsel and require an Officers'  Certificate  or an Opinion of Counsel or
both. The Trustee will not be liable for any action it takes or omits to take in
good faith in reliance on such Officers' Certificate or Opinion of Counsel.

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

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

          (e) The  permissive  right of the Trustee to act hereunder will not be
construed as a duty.

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

          (g) The Trustee  will 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  satisfactory  to the  Trustee  in its  sole  subjective
discretion (which discretion will be exercised in good faith) against the costs,
expenses and  liabilities  that might be incurred by it in compliance  with such
request or direction.

          (h) The Trustee  will not be required to take notice or deemed to have
notice of any Event of Default hereunder,  except failure by the Company to make
any of the payments to the Trustee  pursuant to Section 6.1(a) or (b),  unless a
Responsible  Officer of the Trustee has actual  knowledge  thereof or unless the
Trustee  shall be  specifically  notified in writing of such Event of Default by
the  Company or by one or more of the Holders  and such  notice  references  the
Notes and this Indenture.

          (i) The Trustee may conclusively rely and shall be protected in acting
or  refraining  from  acting  upon  any  resolution,   certificate,   statement,

                                       47
<PAGE>

instrument,  opinion, report, notice, request, direction,  consent, order, bond,
debenture,  note,  other  evidence  of  indebtedness  or other paper or document
believed by it to be genuine and to have been signed or  presented by the proper
party or parties.

          (j) 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 to examine the
books,  records and premises of the Company,  personally or by agent or attorney
at the sole cost of the  Company  and shall  incur no  liability  or  additional
liability of any kind by reason of such inquiry or investigation.

          (k) The rights, privileges, protections, immunities and benefits given
to the Trustee, including,  without limitation, its right to be indemnified, are
extended to, and shall be enforceable  by, the Trustee in each of its capacities
hereunder,  and to each  agent,  custodian  and  other  Person  employed  to act
hereunder.

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

SECTION 7.3.  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 any
Affiliate  of the  Company  with the same  rights  it would  have if it were not
Trustee.  However,  in the  event  that the  Trustee  acquires  any  conflicting
interest (as such term is defined in TIA Section 310(b)), it must eliminate such
conflict within 90 calendar days, apply to the SEC for permission to continue as
trustee (to the extent permitted under TIA Section 310(b)) or resign.  Any Agent
may do the same with like  rights and  duties.  The  Trustee is also  subject to
Sections 7.10 and 7.11 hereof.

SECTION 7.4.  TRUSTEE'S DISCLAIMER.

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

SECTION 7.5.  NOTICE OF DEFAULTS.

          If a Default or Event of Default occurs and is continuing and if it is
known to the Trustee,  the Trustee will mail to Holders of Notes a notice of the
Default or Event of Default  within 90  calendar  days after such event  occurs.
Except in the case of a Default or Event of Default under Section  6.1(a) or (b)
(including,  without limitation, the payment of the Change of Control Payment on
the Change of Control  Payment Date,  the payment of the  applicable  redemption
price on the redemption  date and the payment of the Net Proceeds Offer Price on
the Net Proceeds  Purchase  Date),  the Trustee may  withhold  such notice if it
determines that withholding the notice is in the interests of the Holders of the
Notes.

                                       48
<PAGE>

SECTION 7.6.  REPORTS BY TRUSTEE TO HOLDERS OF THE NOTES.

          Within 60 calendar  days after each May 15  beginning  with the May 15
following the Effective Date, and for so long as Notes remain  outstanding,  the
Trustee  will mail to the Holders of the Notes a brief  report  dated as of such
reporting date that complies with TIA Section 313(a) (but if no event  described
in TIA  Section  313(a) has  occurred  within the twelve  months  preceding  the
reporting  date,  no report need be  transmitted).  The Trustee also will comply
with TIA Section  313(b)(2).  The Trustee will also transmit by mail all reports
as required by TIA Section 313(c).

          A copy of each  report at the time of its  mailing  to the  Holders of
Notes  will be  mailed to the  Company  and  filed  with the SEC and each  stock
exchange,  if any, on which the Notes are listed in  accordance  with and to the
extent  required by TIA Section  313(d).  The Company will  promptly  notify the
Trustee if the Notes become listed on any stock exchange or automatic  quotation
system or any delisting thereof.

SECTION 7.7.  COMPENSATION AND INDEMNITY.

          Absent any other  agreement to the  contrary,  the Company will pay to
the  Trustee  from time to time  compensation  as may be agreed  upon in writing
between the Company and the Trustee for its  acceptance  of this  Indenture  and
services hereunder. The Trustee's compensation will not be limited by any law on
compensation  of a trustee of an express  trust.  The Company will reimburse the
Trustee  promptly upon request for all  reasonable  disbursements,  advances and
expenses  incurred  or  made  by it in  addition  to the  compensation  for  its
services. Such expenses will include the reasonable compensation,  disbursements
and expenses of the Trustee's agents and counsel.

          The Company will indemnify the Trustee and any predecessor Trustee and
their agents, against any and all losses, liabilities or expenses incurred by it
arising out of or in connection  with the  acceptance or  administration  of its
duties under this Indenture,  including the costs and expenses of enforcing this
Indenture against the Company  (including this Section 7.7) and defending itself
against  any claim  (whether  asserted by the Company or any Holder or any other
Person) or liability in connection  with the exercise or  performance  of any of
its powers or duties hereunder, except to the extent any such loss, liability or
expense may be  attributable to its gross  negligence or bad faith.  The Trustee
will promptly  notify the Company of any claim for which it may seek  indemnity.
The Company will defend the claim and the Trustee will cooperate in the defense.
The Trustee may have  separate  counsel and the Company will 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 with
counsel  acceptable  to and  approved by the Trustee  (such  approval  not to be
unreasonably  withheld) 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,  which  consent will not be
unreasonably  withheld.  The  Company  need not  reimburse  the  Trustee for any
expense or indemnity  against any liability or loss of the Trustee to the extent
such expense,  liability or loss is  attributable to the gross  negligence,  bad
faith or willful misconduct of the Trustee.

          The obligations of the Company under this Section 7.7 will survive the
satisfaction and discharge of this Indenture.

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

          When the Trustee incurs expenses or renders services after an Event of
Default  specified in Section 6.1(h) or (i) hereof occurs,  the expenses and the
compensation for the services (including the fees and expenses of its agents and
counsel)  are  intended  to  constitute  expenses  of  administration  under any
Bankruptcy Law.

          The Trustee will comply with the provisions of TIA Section 313(b)(2) .

SECTION 7.8.  REPLACEMENT OF TRUSTEE.

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

          The Trustee may resign in writing upon 30 calendar  days notice and be
discharged from the trust hereby created by so notifying the Company in writing.
The Holders of a majority in principal amount of the then outstanding  Notes may
remove the  Trustee by so  notifying  the Trustee and the Company in writing and
may appoint a successor trustee with the consent of the Company. The Company may
remove the Trustee if:

          (a) the Trustee fails to comply with Section 7.10 hereof;

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

          (c) a  receiver,  Custodian  or  public  officer  takes  charge of the
Trustee or its property; or

          (d) the Trustee becomes incapable of acting.

          If the  Trustee  resigns or is  removed or if a vacancy  exists in the
office of Trustee for any reason,  the Company will promptly  appoint or request
the Trustee to appoint a successor Trustee.  Within one year after the successor
Trustee takes office,  the Holders of a majority in principal amount of the then
outstanding  Notes may  appoint a  successor  Trustee to replace  the  successor
Trustee appointed by the Company.

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

          If the Trustee,  after written request by any Holder of a Note who has
been a Holder of a Note for at least six months,  fails to comply  with  Section
7.10,  such Holder may  petition  any court of  competent  jurisdiction  for the
removal of the Trustee and the appointment of a successor Trustee.

          A  successor  Trustee  will  deliver  a  written   acceptance  of  its
appointment  to  the  retiring  Trustee  and  to  the  Company.  Thereupon,  the
resignation or removal of the retiring  Trustee will become  effective,  and the
successor  Trustee  will have all the  rights,  powers and duties of the Trustee
under this Indenture. The successor Trustee will mail a notice of its succession
to Holders  of the Notes.  The  retiring  Trustee  will  promptly  transfer  all
property held by it as Trustee to the successor Trustee, provided all sums owing
to the Trustee  hereunder have been paid and subject to the Lien provided for in
Section 7.7 hereof.  Notwithstanding replacement of the Trustee pursuant to this
Section 7.8, the  Company's  obligations  under Section 7.7 hereof will continue
for the benefit of the retiring Trustee.

SECTION 7.9.  SUCCESSOR TRUSTEE BY MERGER, ETC.

          If the Trustee consolidates, merges or converts into, or transfers all
or  substantially  all of its corporate trust business to, another  corporation,
the resulting, surviving or transferee corporation without any further act will,
if the  resulting,  surviving or transferee  corporation  is otherwise  eligible
hereunder, be the successor Trustee.

SECTION 7.10.  ELIGIBILITY; DISQUALIFICATION.

          There will at all times be a Trustee  hereunder  that is a corporation
organized and doing  business  under the laws of the United States of America or
of any state  thereof that is authorized  under such laws to exercise  corporate
trustee power, that is subject to supervision or examination by federal or state
authorities   and  that  has  a  combined   capital  and  surplus  of  at  least
US$100,000,000  as set  forth in its most  recent  published  annual  report  of
condition.

          This   Indenture   will  always  have  a  Trustee  who  satisfies  the
requirements  of TIA Section  310(a) (1), (2) and (5). The Trustee  shall comply
with TIA Section 310(b) .

SECTION 7.11.  PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY.

          The Trustee is subject to TIA Section  311(a),  excluding any creditor
relationship  listed in TIA Section  311(b).  A Trustee who has resigned or been
removed will be subject to TIA Section 311(a) to the extent indicated therein.

SECTION 7.12.  LIMITATION   ON   DUTY   OF  TRUSTEE  IN  RESPECT  OF COLLATERAL;
               INDEMNIFICATION

          (a) Beyond the exercise of reasonable care in the custody thereof, the
Trustee shall have no duty as to any  Collateral in its possession or control or
in the  possession or control of any agent or bailee or any income thereon or as
to preservation  of rights against prior parties or any other rights  pertaining
thereto and the Trustee  shall not be  responsible  for filing any  financing or
continuation  statements or recording any documents or instruments in any public
office  at any  time  or  times  or  otherwise  perfecting  or  maintaining  the
perfection  of any security  interest in the  Collateral.  The Trustee  shall be
deemed to have exercised reasonable care in the custody of the Collateral in its
possession if the Collateral is accorded treatment  substantially  equal to that
which it accords its own property and shall not be liable or responsible for any
loss or diminution in the value of any of the  Collateral,  by reason of the act
or omission of any carrier,  forwarding agency or other agent or bailee selected
by the Trustee in good faith.

          (b)  The  Trustee  shall  not  be   responsible   for  the  existence,
genuineness or value of any of the  Collateral or for the validity,  perfection,
priority  or  enforceability  of the  Liens  in any of the  Collateral,  whether
impaired  by  operation  of law or by reason of any action or omission to act on
its part  hereunder,  except to the extent such  action or omission  constitutes
gross negligence, bad faith or wilful misconduct on the part of the Trustee, for
the validity or  sufficiency  of the  Collateral  or any agreement or assignment
contained therein, for the validity of the title of the Company or any Guarantor
to the  Collateral,  for  insuring the  Collateral  or for the payment of taxes,
charges,  assessments  or  Liens  upon the  Collateral  or  otherwise  as to the
maintenance  of the  Collateral.  The Trustee shall have no duty to ascertain or
inquire  as to the  performance  or  observance  of any of  the  terms  of  this
Indenture, the Master Security Agreement, the Collateral Agency Agreement or the
Mortgage by the Company, any Guarantors, or the Collateral Agent. ARTICLE 8

SECTION 8.1.  OPTION TO EFFECT LEGAL DEFEASANCE OR COVENANT DEFEASANCE.

          The Company may, at the option of its Board of Directors  evidenced by
a resolution set forth in an Officers'  Certificate,  at any time, elect to have
either  Section  8.2  or  8.3  hereof  applied  to all  outstanding  Notes  upon
compliance with the conditions set forth below in this Article 8.

                                       51
<PAGE>

SECTION 8.2.  LEGAL DEFEASANCE.

          Upon the  Company's  exercise  under  Section 8.1 hereof of the option
applicable to this Section 8.2, the Company will, subject to the satisfaction of
the  conditions  set  forth in  Section  8.4  hereof,  be  deemed  to have  been
discharged  from its obligations  with respect to all  outstanding  Notes on the
date  the  conditions  set  forth  below  are  satisfied  (hereinafter,   "Legal
Defeasance").  For this purpose, Legal Defeasance means that the Company will be
deemed to have paid and  discharged the entire  Indebtedness  represented by the
outstanding  Notes, which will thereafter be deemed to be "outstanding" only for
the  purposes  of Section 8.6 hereof and the other  Sections  of this  Indenture
referred  to in (a)  and  (b)  below,  and  to  have  satisfied  all  its  other
obligations  under such Notes and this Indenture (and the Trustee,  on demand of
and at the expense of the Company, will execute proper instruments acknowledging
the  same),  except  for the  following  provisions  which  will  survive  until
otherwise terminated or discharged pursuant to this Indenture: (a) the rights of
Holders of outstanding  Notes to receive solely from the trust fund described in
Section 8.4  hereof,  and as more fully set forth in such  Section,  payments in
respect of the  principal  of, and premium,  if any, and interest on, such Notes
when such payments are due, (b) the Company's  obligations  with respect to such
Notes under Article 2 and, to the extent such  obligations  are not satisfied by
payment  from such trust  fund,  Section 4.1  hereof,  (c) the  rights,  powers,
trusts,  duties  and  immunities  of the  Trustee  hereunder  and the  Company's
obligations  in  connection  therewith  and  (d)  this  Article  8.  Subject  to
compliance  with this  Article 8, the Company may exercise its option under this
Section 8.2  notwithstanding  the prior exercise of its option under Section 8.3
hereof.

SECTION 8.3.  COVENANT DEFEASANCE.

          Upon the  Company's  exercise  under  Section 8.1 hereof of the option
applicable  to  this  Section  8.3,  and  subject  to  the  satisfaction  of the
conditions  set forth in Section 8.4 hereof,  the Company will be released  from
its  obligations  under the covenants  contained in Sections 4.3, 4.4, 4.5, 4.7,
4.8, 4.9, 4.10,  4.11,  4.12, 4.13, 4.14, 4.16, 4.17, 4.18, 4.19, 4.20, 5.1, and
5.2 with respect to the  outstanding  Notes on and after the date the conditions
set forth below are  satisfied  (hereinafter,  "Covenant  Defeasance"),  and the
Notes  will  thereafter  be deemed not  "outstanding"  for the  purposes  of any
direction,   waiver,   consent  or  declaration  or  act  of  Holders  (and  the
consequences  of any  thereof)  in  connection  with  such  covenants,  but will
continue to be deemed  "outstanding" for all other purposes  hereunder (it being
understood  that  such  Notes  will not be  deemed  outstanding  for  accounting
purposes). For this purpose, Covenant Defeasance means that, with respect to the
outstanding  Notes,  the Company need not comply with and will have no liability
in respect of any term,  condition or limitation set forth in any such covenant,
whether directly or indirectly,  by reason of any reference  elsewhere herein to
any such  covenant  or by reason of any  reference  in any such  covenant to any
other provision herein or in any other document and such omission to comply will
not  constitute a Default or an Event of Default under Section 6.1 hereof,  but,
except as specified  above,  the remainder of this Indenture and such Notes will
be unaffected  thereby.  In addition,  upon the Company's exercise under Section
8.1 hereof of the option  applicable to this Section 8.3 hereof,  subject to the
satisfaction of the conditions set forth in Section 8.4 hereof, Sections 6.1(d),
(f) and (g) hereof will not constitute Events of Default.

SECTION 8.4.  CONDITIONS TO LEGAL OR COVENANT DEFEASANCE.

          In order to exercise either Legal  Defeasance or Covenant  Defeasance,
the Company must irrevocably deposit, or cause to be deposited, with the Trustee
(or another trustee satisfying the requirements of this Indenture), in trust for
such purpose,  (1) money in an amount,  (2) non-callable  Government  Securities
which through the scheduled payment of principal,  interest and premium, if any,
in respect  thereof in  accordance  with their terms will provide not later than
one day  before  the due  date  of any  payment  money  in an  amount,  or (3) a
combination  thereof,  sufficient,  without  reinvestment,  in the  opinion of a
nationally  recognized  firm of independent  public  accountants  expressed in a
written certification thereof delivered to the Trustee, to pay the principal of,
and premium,  if any, and interest on, the outstanding Notes at maturity or upon
redemption,  together with all other  amounts  payable by the Company under this
Indenture.  Such Legal  Defeasance or Covenant  Defeasance will become effective
123 calendar days after such deposit if and only if:

                                       52
<PAGE>

          (i)  no Default or Event of Default  with  respect to the Notes  shall
               have occurred and be continuing  immediately prior to the time of
               such deposit;

          (ii) no  Default  or Event of Default  pursuant  to Section  6.1(h) or
               6.1(i)  shall have  occurred at any time in the period  ending on
               the  123rd  day  after  the  date of  such  deposit  and  will be
               continuing on such 123rd day;

          (iii)such  defeasance  does not result in a breach or violation of, or
               constitute  a default  under,  any other  material  agreement  or
               instrument  to  which  the  Company  is a party or by which it is
               bound (and, in furtherance of such condition, no Default or Event
               of Default will result under this Indenture due to the incurrence
               of  Indebtedness  to fund such deposit and the  entering  into of
               customary documentation in connection therewith, even though such
               documentation  may contain  provisions  that would otherwise give
               rise to a Default or Event of Default); and

          (iv) the Company has  delivered  to the Trustee (A) (1) in the case of
               Legal  Defeasance,  an Opinion of Counsel to the effect  that (x)
               there has been published by the Internal Revenue Service a ruling
               or (y) since the Effective  Date,  there has been a change in the
               applicable  federal  income tax law, in either case to the effect
               that,  and based  thereon  such  Opinion of Counsel  will confirm
               that, the Holders of the Notes will not recognize income, gain or
               loss for  federal  income tax  purposes as a result of such Legal
               Defeasance  and will be subject to federal income tax on the same
               amounts,  in the same  manner and at the same times as would have
               been the case if such Legal  Defeasance had not occurred,  or (2)
               in the case of Covenant Defeasance,  an Opinion of Counsel to the
               effect that the Holders of the Notes will not  recognize  income,
               gain or loss for federal  income tax purposes as a result of such
               Covenant  Defeasance and will be subject to federal income tax on
               the same  amount,  in the same  manner  and at the same  times as
               would  have  been the case if such  Covenant  Defeasance  had not
               occurred;  (B) an Opinion of Counsel to the effect that after the
               123rd day after the date of such  deposit,  the trust  funds will
               not be  subject  to the  effect  of  any  applicable  bankruptcy,
               insolvency,  reorganization or similar laws affecting  creditors'
               rights generally;  (C) an Officers' Certificate stating that such
               deposit was not made by the Company with the intent of preferring
               the Holders of Notes over the other creditors of the Company with
               the  intent  of  defeating,  hindering,  delaying  or  defrauding
               creditors  of  the  Company  or  others;  and  (D)  an  Officers'
               Certificate  and an Opinion of  Counsel,  each  stating  that all
               conditions   precedent  relating  to  such  Legal  Defeasance  or
               Covenant Defeasance have been complied with.

SECTION 8.5.  DISCHARGE.

          If   (i)  either  (a) all such  Notes  theretofore  authenticated  and
               delivered  except lost,  stolen or destroyed Notes that have been
               replaced  or  paid  and  Notes  for  whose   payment   money  has
               theretofore   been  deposited  in  trust  with  the  Trustee  and
               thereafter  repaid to the Company or discharged  from such trust)
               have been delivered to the Trustee for  cancellation;  or (b) all
               such  Notes  not   heretofore   delivered   to  the  Trustee  for
               cancellation  have  become due and payable by their terms and the
               Company has irrevocably  deposited or caused to be deposited with
               the  Trustee  funds  in  an  amount  of  money  in  U.S.  dollars
               sufficient to pay and discharge  the entire  indebtedness  on the
               Notes not theretofore  delivered to the Trustee for cancellation,
               for the principal  amount,  premium,  if any,  accrued and unpaid
               interest,  to the date of such deposit  together with irrevocable
               instructions from the Company directing the Trustee to apply such
               funds to the payment thereof; (ii) the Company has paid all other
               sums  payable by it under this  Indenture;  and (iii) the Company
               has delivered  irrevocable  instructions  to the Trustee to apply
               the deposited money toward the payment of the Notes (except lost,
               stolen or  destroyed  Notes that have been  replaced  or paid and
               Notes for whose payment money has been  theretofore  deposited in
               trust with the  Trustee and  thereafter  repaid to the Company or
               discharged from such trust) at maturity, as the case may be, then
               this  Indenture  will cease to be of further force or effect and,
               at  the  written  request  of  the  Company,  accompanied  by  an
               Officers'  Certificate and Opinion of Counsel,  each stating that
               all  conditions  precedent  provided  for herein  relating to the
               satisfaction  and discharge of this  Indenture have been complied
               with,  and  upon  payment  of the  costs,  charges  and  expenses
               incurred or to be incurred by the Trustee in relation  thereto or
               in carrying out the  provisions  of this  Indenture,  the Trustee
               will satisfy and discharge this Indenture ("Discharge"); PROVIDED
               that the  Company's  obligations  with  respect to the payment of
               principal, premium, if any, and interest will not terminate until
               the Trustee shall apply the moneys so deposited to the payment to
               the Holders of Notes of all sums due and to become due thereon.

SECTION 8.6.  DEPOSITED  MONEY  AND  GOVERNMENT  SECURITIES TO BE HELD IN TRUST;
              OTHER MISCELLANEOUS PROVISIONS.

          Subject to Section 8.7  hereof,  all money and  Government  Securities
(including the proceeds thereof) deposited with the Trustee (or other qualifying
trustee,  collectively for purposes of this Section 8.6, the "Trustee") pursuant
to Section 8.4 or 8.5 hereof in respect of the outstanding Notes will be held in
trust and applied by the Trustee,  in  accordance  with the  provisions  of such
Notes and this Indenture,  to the payment, either directly or through any Paying
Agent (including the Company or any of its Subsidiaries or Affiliates  acting as
Paying Agent) as the Trustee may determine,  to the Holders of such Notes of all
sums due and to become due thereon in respect of principal, premium, if any, and
interest  but such money need not be  segregated  from other funds except to the
extent required by law.

          The Company will pay and indemnify the Trustee against any tax, fee or
other charge imposed on or assessed  against the money or Government  Securities
deposited pursuant to this Section 8.6 or the principal and interest received in
respect thereof other than any such tax, fee or other charge which by law is for
the account of the Holders of the outstanding Notes.

          Anything  in  this  Article  8 to the  contrary  notwithstanding,  the
Trustee will deliver or pay to the Company from time to time upon the request of
the Company any money or  Government  Securities  held by it as provided in this
Section 8.6 which, in the opinion of a nationally recognized firm of independent
public accountants expressed in a written certification thereof delivered to the
Trustee (which may be the opinion  delivered  under Section 8.4 hereof),  are in
excess of the amount  thereof  that would then be  required to be  deposited  to
effect an equivalent Legal Defeasance, Covenant Defeasance or Discharge.

SECTION 8.7.  REPAYMENT TO COMPANY.

          Any money deposited with the Trustee or any Paying Agent, or then held
by the  Company  or any of its  Subsidiaries  or  Affiliates,  in trust  for the
payment of the  principal  of, or premium,  if any, or interest on, any Note and
remaining  unclaimed  for one year after such  principal,  premium,  if any,  or
interest  has become due and payable  will be paid to the Company on its request
or (if then held by the Company or any of its  subsidiaries or Affiliates)  will
be discharged from such trust; and the Holder of such Note will  thereafter,  as
an unsecured general creditor, look only to the Company for payment thereof, and

                                       54
<PAGE>

all  liability  of the Trustee or such Paying  Agent with  respect to such trust
money, and all liability of the Company or any of its Subsidiaries or Affiliates
as trustee thereof, will thereupon cease; PROVIDED, HOWEVER, that the Trustee or
such Paying Agent,  before being required to make any such repayment,  shall, at
the pre-paid expense of the Company, cause to be published once, in The New York
Times and The Wall Street  Journal  (national  edition),  notice that such money
remains  unclaimed and that, after a date specified  therein,  which will not be
less than 30 calendar days from the date of such  notification  or  publication,
any  unclaimed  balance  of such  money  then  remaining  will be  repaid to the
Company.

SECTION 8.8.  REINSTATEMENT.

          If the  Trustee or Paying  Agent is unable to apply any United  States
dollars or  Government  Securities  in  accordance  with Section 8.2, 8.3 or 8.5
hereof,  as the case may be, by reason of any order or  judgment of any court or
governmental  authority  enjoining,  restraining or otherwise  prohibiting  such
application,  then the Company's  obligations under this Indenture and the Notes
will be revived and  reinstated  as though no deposit had  occurred  pursuant to
Section 8.2, 8.3 or 8.5 hereof until such time as the Trustee or Paying Agent is
permitted  to apply all such assets in  accordance  with Section 8.2, 8.3 or 8.5
hereof,  as the case may be; PROVIDED,  HOWEVER,  that, if the Company makes any
payment of principal of, or premium,  if any, or interest on, any Note following
the  reinstatement  of its  obligations,  the Company will be  subrogated to the
rights of the Holders of such Notes to receive  such  payment  from the money or
Government Securities held by the Trustee or Paying Agent.

                                    ARTICLE 9
                        AMENDMENT, SUPPLEMENT AND WAIVER

SECTION 9.1.  WITHOUT CONSENT OF HOLDERS OF NOTES.

          Notwithstanding  Section  9.2 of this  Indenture,  the Company and the
Trustee may amend or supplement  this Indenture,  the Security  Documents or the
Guarantees without the consent of any Holder:

          (a) to cure any ambiguity, defect or inconsistency;

          (b) to provide for uncertificated  Notes in addition to or in place of
Certificated Notes;

          (c) to provide for the assumption of the Company's  obligations to the
Holders of Notes in the case of a merger or consolidation  pursuant to Article 5
hereof;

          (d) to make any change  that would  provide any  additional  rights or
benefits to the Holders of the Notes or that does not adversely affect the legal
rights hereunder of any such Holder; or

          (e) to  comply  with  requirements  of the SEC in order to  effect  or
maintain the qualification of this Indenture under the TIA as then in effect.

          Upon the request of the Company  accompanied  by a  resolution  of its
Board of Directors authorizing the execution of any such amended or supplemental
Indenture, and upon receipt by the Trustee of the documents described in Section
7.2 hereof,  the  Trustee  will join with the  Company in the  execution  of any
amended or supplemental  Indenture  authorized or permitted by the terms of this
Indenture and to make any further  appropriate  agreements and stipulations that
may be therein contained.

SECTION 9.2.  WITH CONSENT OF HOLDERS OF NOTES.

          Except as  provided  in  Section  9.1 and in this  Section  9.2,  this
Indenture, the Notes, the Security Documents or the Guarantees may be amended or
supplemented by the Company, each Guarantor, and the Trustee with the consent of
the  Holders  of at least a  majority  in  principal  amount of the  Notes  then
outstanding (including, without limitation, consents obtained in connection with
a purchase of, or tender offer or exchange offer for,  Notes),  and,  subject to

                                       55
<PAGE>

Sections  6.4 and 6.7 and the  second to last  paragraph  of  Section  6.1,  any
existing Default,  Event of Default (other than a Default or Event of Default in
the payment of principal of, premium,  if any, or interest on, the Notes, except
a payment  default  resulting from an  acceleration  that has been rescinded) or
non-compliance  with any provision of this  Indenture,  the Notes,  the Security
Documents or the  Guarantees  may be waived with the consent of the Holders of a
majority in principal amount of the then outstanding  Notes (including  consents
obtained in connection  with a purchase of, or a tender offer or exchange  offer
for, the Notes).

          Upon the request of the Company  accompanied  by a  resolution  of its
Board of Directors authorizing the execution of any such amended or supplemental
Indenture  (or  amendment  or  supplement  to  the  Security  Documents  or  the
Guarantees,  as the case  may be),  and upon  the  filing  with the  Trustee  of
evidence  satisfactory  to the Trustee of the consent of the Holders of Notes as
aforesaid, and upon receipt by the Trustee of the documents described in Section
7.2 hereof,  the Trustee  will join with the  Company in the  execution  of such
amended or  supplemental  Indenture  (or amendment or supplement to the Security
Documents  or the  Guarantees,  as the  case may  be),  and to make any  further
appropriate  agreements and stipulations that may be therein contained,  but the
Trustee  will not be  obligated  to enter  into  such  amended  or  supplemental
Indenture or any other document in connection with this Indenture that adversely
affects its own rights,  duties,  liabilities or immunities under this Indenture
or otherwise.

          It will not be necessary for the consent of the Holders of Notes under
this Section 9.2 to approve the  particular  form of any  proposed  amendment or
waiver,  but it will  be  sufficient  if such  consent  approves  the  substance
thereof.

          After an  amendment,  supplement  or waiver  under  this  Section  9.2
becomes  effective,  the  Company  will mail to the  Holders  of Notes  affected
thereby a notice briefly  describing the  amendment,  supplement or waiver.  Any
failure of the Company to mail such  notice,  or any defect  therein,  will not,
however,  in any way  impair or  affect  the  validity  of any such  amended  or
supplemental  Indenture or waiver.  Subject to Sections 6.4 and 6.7 hereof,  the
Holders of a majority  in  principal  amount of the Notes then  outstanding  may
waive  compliance in a particular  instance by the Company with any provision of
this  Indenture  or the Notes.  However,  without  the  consent  of each  Holder
affected,  an amendment  or waiver may not (with  respect to any Notes held by a
non-consenting Holder):

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

          (b) reduce the  principal of or change the fixed  maturity of any Note
or alter the provisions  with respect to the redemption of the Notes (other than
provisions relating to Section 3.7);

          (c) reduce the rate of or change the time for  payment of  interest on
any Note;

          (d) waive a Default or Event of Default  in the  payment of  principal
of, or  premium,  if any,  or  interest  on the Notes  (except a  rescission  of
acceleration  of the Notes by the  Holders of at least a majority  in  aggregate
principal  amount of the Notes and a waiver of the payment default that resulted
from  such  acceleration)  or reduce  the  Change of  Control  Payment,  the Net
Proceeds Offer Price or the applicable redemption price;

          (e) make any Note  payable  in money  other  than  that  stated in the
Notes;

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

          (g) waive a  redemption  payment  with respect to any Note (other than
provisions relating to Section 3.7);

          (h)  release  any  Collateral  from the Lien  created by the  Security
Documents, except in accordance with the terms thereof, or amend such terms; or

          (i) make any change in the foregoing amendment and waiver provisions.

                                       56

SECTION 9.3.  COMPLIANCE WITH TRUST INDENTURE ACT.

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

SECTION 9.4.  REVOCATION AND EFFECT OF CONSENTS.

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

          The Company may,  but will 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
sentence of the immediately preceding paragraph,  those Persons who were Holders
at such record date (or their duly designated proxies),  and only those Persons,
will be  entitled to consent to such  amendment  or waiver or revoke any consent
previously given,  whether or not such Persons continue to be Holders after such
record date.  No consent  will be valid or  effective  for more than 90 calendar
days after such record date  except to the extent that the  requisite  number of
consents to the amendment,  supplement or waiver have been obtained  within such
90-day period or as set forth in the next paragraph of this Section 9.4.

          After an amendment,  supplement or waiver becomes  effective,  it will
bind every  Holder,  unless it makes a change  described  in any of clauses  (a)
through (i) of Section 9.2, in which case, the  amendment,  supplement or waiver
will  bind  only  each  Holder  of a Note  who  has  consented  to it and  every
subsequent  Holder  of a Note or  portion  of a Note  that  evidences  the  same
indebtedness  as the  consenting  Holder's  Note,  PROVIDED that any such waiver
shall not impair or affect the right of any other  Holder to receive  payment of
principal,  premium, or interest on a Note, on or after the respective dates set
for such amounts to become due and payable  expressed in such Note,  or to bring
suit for the enforcement of any such payment on or after such respective dates.

SECTION 9.5.  NOTATION ON OR EXCHANGE OF NOTES.

          If an amendment, supplement or waiver changes the terms of a Note, the
Trustee  may  require  the Holder of the Note to  deliver  it to the  Trustee or
require the Holder to put an  appropriate  notation on the Note. The Trustee may
place an appropriate  notation on the Note about the changed terms and return it
to the Holder.  Alternatively,  if the Company or the Trustee so determines, the
Company in exchange for the Note will issue and the Trustee will  authenticate a
new Note that reflects the changed  terms.  Any failure to make the  appropriate
notation or to issue a new Note shall not affect the validity of such amendment,
supplement or waiver.

SECTION 9.6.  TRUSTEE TO SIGN AMENDMENTS, ETC.

          The Trustee will sign any amended or supplemental Indenture authorized
pursuant to this Article 9 if the  amendment or  supplement  does not  adversely
affect  the  rights,  duties,  liabilities  or  immunities  of the  Trustee.  In
executing any amended or supplemental indenture, the Trustee will be entitled to
receive and (subject to Section 7.1) will be fully protected in relying upon, an
Officers' Certificate and an Opinion of Counsel to the effect that the execution
of such amended or  supplemental  indenture is  authorized  or permitted by this
Indenture.

SECTION 9.7.  PAYMENTS FOR CONSENT.

          The Company will not, and will not permit any of its  Subsidiaries to,
directly or indirectly,  pay or cause to be paid any  consideration,  whether by
way of  interest,  fee or  otherwise,  to any  Holder  of any Notes for or as an
inducement  to any consent,  waiver or amendment of any terms or  provisions  of
this Indenture,  the Notes, the Security Documents or the Guarantees unless such
consideration  is offered to be paid or is paid to all Holders of the Notes that
so consent,  waive or agree to amend in the time frame set forth in solicitation
documents relating to such consent, waiver or agreement.

                                   ARTICLE 10
                             COLLATERAL AND SECURITY

SECTION 10.1.  SECURITY DOCUMENTS.

          The due and punctual payment of the principal and premium, if any, of,
and  interest  on,  the  Notes  when and as the same  shall be due and  payable,
whether on an Interest Payment Date, at maturity,  by acceleration,  repurchase,
redemption or otherwise,  interest on the overdue  principal of and interest (to
the extent  permitted by law), if any, on the Notes and performance of all other
Obligations  of the Company to the  Holders of the Notes and the  Trustee  under
this  Indenture  with respect to the Notes,  shall be secured as provided in the
Security Documents.

          The Company shall, and shall cause each of its Restricted Subsidiaries
to,  do or cause to be done all such  acts and  things  as may be  necessary  or
proper,  or as may be required by the provisions of the Security  Documents,  to
assure and confirm to the Trustee and the Collateral  Agent,  for the benefit of
the  Trustee  and  the  Holders  of the  Notes,  the  security  interest  in the
Collateral  contemplated hereby and by the Security  Documents,  as from time to
time  constituted,  so as to render  the same  available  for the  security  and
benefit of this  Indenture  and the Notes  according  to the intent and purposes
herein and therein  expressed.  The Company  shall,  and shall cause each of its
Restricted  Subsidiaries to, take, upon request of the Trustee or the Collateral
Agent,  any and all actions  required to cause the Security  Documents to create
and maintain,  valid and enforceable,  perfected  (except as expressly  provided
herein  or  therein),  Liens  in and on all  the  Collateral,  in  favor  of the
Collateral  Agent for the  benefit of the  Trustee  and the Holders of the Notes
superior to and prior to the rights of all other third  Persons,  and subject to
no other Liens, other than Permitted Liens.

          The  Company  represents,  covenants  and agrees  that it has,  at all
relevant times has had, and that it and its Restricted Subsidiaries shall at all
times have,  full right,  power and lawful  authority to grant,  bargain,  sell,
release, convey, hypothecate, assign, mortgage, pledge, transfer and confirm the
property  constituting  the  Collateral,  in the manner and form provided in the
Security  Documents,   free  and  clear  of  all  Liens,  pledges,  charges  and
encumbrances  whatsoever  (other  than  Permitted  Liens),  and that (i) it will
forever  warrant  and  defend  the title to the same  against  the claims of all
persons whatsoever  (except as to Permitted Liens),  (ii) to the extent provided
by the  Master  Security  Agreement,  it and  the  Restricted  Subsidiaries,  as
applicable,  will  execute,  acknowledge  and  deliver  to  the  Trustee  or the
Collateral  Agent  such  further  assignments,  transfers,  assurances  or other
instruments  as the Trustee or the Collateral  Agent may  reasonably  require or
request,  and (iii) to the extent provided by the Master Security Agreement,  it
and the Restricted Subsidiaries,  as applicable, will do or cause to be done all
such acts and things as may be necessary or proper, or as may be required by the
Trustee or the  Collateral  Agent,  to assign and confirm to the Trustee and the
Collateral  Agent  the  Collateral,  or any part  thereof,  as from time to time
constituted,  so as to render the same available for the security and benefit of
the  Security  Documents,  this  Indenture  and the Notes.  The Company and each
Restricted  Subsidiary  further  covenants  and agrees that the Master  Security
Agreement  and the Mortgage  each creates or will create,  as the case may be, a
valid  first-ranking Lien (subject to Permitted Liens) on the Collateral subject
thereto.

SECTION 10.2.  OPINIONS.

          The Company  shall  furnish to the Trustee  within  three months after
each  anniversary  of the date hereof,  an Opinion of Counsel,  dated as of such
date of delivery,  stating  either that (i) in the opinion of such counsel,  all
action has been taken with respect to the recording,  registering,  filing,  re-
recording,  re-registering  and  refiling  of the  Security  Documents  and  all
supplements  thereto or to this Indenture,  financing  statements,  continuation
statements or other instruments of further assurance as is necessary to maintain
the Liens of the Security  Documents  and reciting the details of such action or
(ii) in the opinion of such  Counsel,  no such action is  necessary  to maintain
such  Liens,  which  Opinion of Counsel  also shall  state what  actions it then
believes are  necessary to maintain the  effectiveness  of such Liens during the
next two years.

SECTION 10.3.  RELEASE OF COLLATERAL.

          (a) Unless a Default or Event of Default  shall have  occurred  and be
continuing,  Collateral shall be released from the Liens created by the Security
Documents from time to time at the sole cost and expense of the Company:

          (i)upon payment in full of the Notes and all other  Obligations of the
Company to the Holders of the Notes and the Trustee  under this  Indenture  with
respect to the Notes then due and owing, or

          (ii) upon the sale or other disposition of such Collateral pursuant to
an Asset Sale made in  accordance  with  Section  4.10  hereof or  pursuant to a
transaction  which  is  deemed  not  to be an  Asset  Sale  as  provided  in the
definition of such term,

PROVIDED,  that the Trustee shall not release any Lien on any Collateral  unless
and until it shall have received an Officers'  Certificate  certifying  that all
conditions  precedent  hereunder have been met and such other documents required
by Section 10.4 hereof.  Upon compliance with the above provisions,  the Trustee
shall  execute,  deliver or  acknowledge  any necessary or proper  instrument of
termination,  satisfaction  or release to evidence the release of any Collateral
permitted to be released pursuant to this Indenture or the Security Documents;

          (b) The disposition of Inventory or Accounts in the ordinary course of
business may be made without delivery to the Trustee of certificates required by
TIA ss.314(d); and

          (c) The  release  of any  Collateral  from the  terms of the  Security
Documents  shall not be deemed to impair the  security  under this  Indenture in
contravention of the provisions  hereof and of the Security  Documents if and to
the extent the  Collateral is released  pursuant to the terms of this  Indenture
and the Security Documents.

SECTION 10.4.  CERTIFICATES OF THE COMPANY.

          The  Company  shall  furnish  to the  Trustee  prior to each  proposed
release  of  Collateral  other  than by reason of  transactions  referred  to in
Section 10.3(b),  all documents  required by TIA ss. 314(d). The Trustee may, to
the extent  permitted  by  Sections  7.1 and 7.2  hereof,  accept as  conclusive
evidence of compliance with the foregoing provisions the appropriate  statements
contained in such  instruments.  Any certificate or opinion  required by TIA ss.
314(d) may be made by an Officer of the  Company  except in cases  where TIA ss.
314(d)  requires  that such  certificate  or opinion  be made by an  independent
engineer, appraiser or other expert within the meaning of TIA ss. 314(d).

SECTION 10.5. AUTHORIZATION OF  ACTIONS  TO  BE  TAKEN  BY THE TRUSTEE UNDER THE
              SECURITY DOCUMENTS.

Holders,  on behalf of the  Holders,  take all  actions  it deems  necessary  or
appropriate  in order to (a) enforce any of the terms of the Security  Documents
and (b)  collect  and  receive  any and all  amounts  payable  in respect of the
Obligations of the Company and the Guarantors hereunder.  The Trustee shall have
the power to institute and to maintain such suits and proceedings as it may deem

                                       59
<PAGE>

expedient to prevent any  impairment  of the  Collateral by any acts that may be
unlawful or in violation of the Security  Documents or this Indenture,  and such
suits and  proceedings  as the Trustee may deem expedient to preserve or protect
its  interests  and the  interests of the Holders in the  Collateral  (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 the
Trustee).

SECTION 10.6. AUTHORIZATION  OF  RECEIPT  OF  FUNDS  BY  THE  TRUSTEE  UNDER THE
              SECURITY DOCUMENTS.

          The Trustee is  authorized to receive any funds for the benefit of the
Holders  distributed  under  the  Security   Documents,   and  to  make  further
distributions  of such funds to the Holders  according to the provisions of this
Indenture and the Security Documents.

SECTION 10.7.TRUSTEE NOT LIABLE FOR ACTIONS OF COLLATERAL AGENT.

                                   ARTICLE 11
                               GUARANTEE OF NOTES

SECTION 11.1.  GUARANTEE.

          (a) Each  Guarantor  hereby  jointly  and  severally  irrevocably  and
unconditionally  guarantees,  as a primary  obligor  and not a  surety,  to each
Holder of a Note now or hereafter authenticated and delivered by the Trustee and
to the Trustee and its successors and assigns,  irrespective of the validity and
enforceability  of this  Indenture,  the Notes or the Obligations of the Company
hereunder  or  thereunder,  (i) the due and punctual  payment of the  principal,
premium,  if any, interest (including  post-petition  interest in any proceeding
under any Bankruptcy Law whether or not an allowed claim in such  proceeding) on
overdue principal,  premium,  if any, and interest,  if lawful on such Note, and
(ii) all other monetary Obligations payable by the Company, under this Indenture
(including  under Section 7.7 hereof) and the Notes (all of the foregoing  being
hereinafter collectively called the "Guaranteed  Obligations"),  when and as the
same shall become due and payable,  whether by  acceleration  thereof,  call for
redemption  or  otherwise  (including  amounts that would become due but for the
operation of the automatic stay under Section 362(a) of the Bankruptcy Code), in
accordance  with  the  terms of any such  Note and of this  Indenture,  subject,
however,  in the case of (i) and (ii)  above,  to the  limitations  set forth in
Section  11.3  hereof.   Each  Guarantor   hereby  agrees  that  the  Guaranteed
Obligations hereunder shall be absolute and unconditional,  irrespective of, and
shall be unaffected  by, any failure to enforce the  provisions of any such Note
or this Indenture, any waiver, modification or indulgence granted to the Company
with respect  thereto,  the recovery of any  judgment  against the Company,  any
action  to  enforce  the  same  by the  Holders  or the  Trustee,  or any  other
circumstances which might otherwise constitute a legal or equitable discharge of
a surety or guarantor.  Each  Guarantor  hereby waives  diligence,  presentment,
filing of claims  with a court in the  event of a merger  or  bankruptcy  of the
Company,  any right to require a  proceeding  first  against  the  Company,  the
benefit of  discussion,  protest or notice with  respect to any such Note or the
Indebtedness  evidenced thereby and all demands  whatsoever,  and covenants that
this Guarantee  shall not be discharged as to any such Note except by payment in
full of the  principal  thereof,  premium,  if any,  and  all  accrued  interest
thereon.

          (b) Each Guarantor  further  agrees that this Guarantee  constitutes a
guarantee of payment,  performance  and compliance when due (and not a guarantee
of  collection)  and waives  any right to require  that any resort be had by any
Holder  or  the  Trustee  to  any  Note  held  for  payment  of  the  Guaranteed
Obligations.

                                       60
<PAGE>

          (c) Each  Guarantor  agrees  that it will not  exercise  any  right of
subrogation  in  relation  to the  Holders  or the  Trustee  in  respect  of any
Guaranteed  Obligations  until  such time as the Notes and all other  Guaranteed
Obligations are indefeasibly  paid in full. Each Guarantor  further agrees that,
as between such Guarantor,  on the one hand, and the Holders and the Trustee, on
the  other  hand,  (i)  the  maturity  of  the  Guaranteed  Obligations  may  be
accelerated  as  provided  in  Article 6 for the  purposes  of such  Guarantor's
Guarantee,  notwithstanding any stay, injunction or other prohibition preventing
such  acceleration  in respect of the  Guaranteed  Obligations,  and (ii) in the
event of any  declaration  of  acceleration  of such  Guaranteed  Obligations as
provided in Article 6 hereof,  such Guaranteed  Obligations  (whether or not due
and payable)  shall  forthwith  become due and payable by such Guarantor for the
purpose of this Article 11.

          (d) Each  Guarantor  also agrees to pay any and all costs and expenses
(including  reasonable  attorneys' fees and expenses) incurred by the Trustee or
any Holder in enforcing any rights under this Article 11.

          (e) The  Guarantee  set forth in this Article 11 shall not be valid or
become  obligatory for any purpose with respect to a Note until the  certificate
of  authentication  on such Note shall  have been  signed by or on behalf of the
Trustee.

          (f) Each  Guarantee is secured by a first priority  security  interest
(subject to Permitted Liens) in the Collateral.

SECTION 11.2.  GUARANTEE UNCONDITIONAL, ETC.

          Upon  failure of payment  when due of any  Guaranteed  Obligation  for
whatever reason,  each Guarantor will be obligated to pay the same  immediately.
Each Guarantor hereby agrees that its obligations hereunder shall be continuing,
absolute  and  unconditional,  irrespective  of: the  recovery  of any  judgment
against  the  Company or any  Guarantor;  any  extension,  renewal,  settlement,
compromise,  waiver or release in respect of any obligation of the Company under
this Indenture or any Note, by operation of law or otherwise;  any  modification
or amendment of or supplement to this  Indenture or any Note;  any change in the
corporate  existence,  structure or ownership of the Company, or any insolvency,
bankruptcy,  reorganization or other similar proceeding affecting the Company or
its  assets or any  resulting  release or  discharge  of any  obligation  of the
Company  contained in this  Indenture or any Note;  the  existence of any claim,
set-off or other  rights  which any  Guarantor  may have at any time against the
Company,  the Trustee,  any Holder or any other  Person,  whether in  connection
herewith or any  unrelated  transactions;  PROVIDED,  that nothing  herein shall
prevent  the  assertion  of any  such  claim  by  separate  suit  or  compulsory
counterclaim;  any  invalidity  or  unenforceability  relating to or against the
Company  for any  reason of this  Indenture  or any Note,  or any  provision  of
applicable  law or regulation  purporting to prohibit the payment by the Company
of the  principal,  premium,  if any,  or  interest  on any  Note  or any  other
Guaranteed Obligation;  or any other act or omission to act or delay of any kind
by the  Company,  the  Trustee,  any  Holder  or any  other  Person or any other
circumstance  whatsoever  which might,  but for the  provisions  of this Section
11.2,  constitute a legal or equitable discharge of the Guarantors'  obligations
hereunder.  Subject to Section 11.5,  each  Guarantor  hereby waives  diligence,
presentment,  demand of  payment,  filing of claims with a court in the event of
insolvency or bankruptcy of the Company, any right to require a proceeding first
against the Company,  protest,  notice and all demand  whatsoever  and covenants
that this Guarantee will not be discharged except by the complete performance of
the obligations  contained in the Notes,  this Indenture and in this Article 11.
Each  Guarantor's  obligations  hereunder  shall remain in full force and effect
until the Indenture  shall have  terminated and the principal of and interest on
the Notes and all other Guaranteed  Obligations shall have been paid in full. If
at any time any payment of the principal of or interest on any Note or any other
payment  in  respect  of any  Guaranteed  Obligation  is  rescinded  or  must be
otherwise restored or returned upon the insolvency, bankruptcy or reorganization
of the Company or otherwise, each Guarantor's obligations hereunder with respect
to such payment  shall be reinstated as though such payment had been due but not
made at such time,  and this  Article  11, to the extent  therefore  discharged,
shall be reinstated in full force and effect. Each Guarantor  irrevocably waives
any  and  all  rights  to  which  it may be  entitled,  by  operation  of law or
otherwise,  upon making any payment  hereunder to be subrogated to the rights of
the payee  against the Company  with  respect to such payment or otherwise to be
reimbursed, indemnified or exonerated by the Company in respect thereof.

SECTION 11.3.  LIMITATION OF GUARANTOR'S LIABILITY.

          Each  Guarantor  and by  its  acceptance  hereof  each  Holder  hereby
confirms that it is the intention of all such parties that the guarantee by such
Guarantor  pursuant to its  Guarantee  not  constitute a fraudulent  transfer or
conveyance  for purposes of the  Bankruptcy  Law,  federal,  state or provincial
fraudulent  conveyance  laws  or  other  legal  principles.  To  effectuate  the
foregoing  intention,  the Holders and each Guarantor hereby  irrevocably  agree
that the  obligations of each Guarantor  under its Guarantee shall be limited to
the maximum amount which,  after giving effect to all other contingent and fixed
liabilities of such Guarantor and after giving effect to any collections from or
payments  made  by or on  behalf  of  any  other  Guarantor  in  respect  of the
obligations of such other Guarantor under its Guarantee of the Notes or pursuant
to Section 11.4 hereof,  will result in the  obligations of such Guarantor under
its Guarantee not  constituting  such  fraudulent  transfer or conveyance  under
applicable law.

SECTION 11.4.  CONTRIBUTION.

          In order to  provide  for just and  equitable  contribution  among the
Guarantors,  the  Guarantors  agree,  INTER SE, that in the event any payment or
distribution  is  made  by any  Guarantor  (a  "Funding  Guarantor")  under  its
Guarantee,  such Funding  Guarantor shall be entitled to a contribution from all
other  Guarantors  in a PRO RATA amount based on the Adjusted Net Assets of each
Guarantor (including the Funding Guarantor), determined in accordance with GAAP,
for all  payments,  damages and expenses  incurred by that Funding  Guarantor in
discharging  the  Company's  obligations  with respect to the Notes or any other
Guarantor's obligations with respect to the Guarantee.

SECTION 11.5.  RELEASE.

          Upon the  sale or  disposition  of all of the  Equity  Interests  of a
Guarantor to an entity which is not the Company or a  Restricted  Subsidiary  of
the  Company,  which is  otherwise  in  compliance  with  this  Indenture,  such
Guarantor shall be deemed released from all its obligations under this Indenture
without  any further  action  required on the part of the Trustee or any Holder;
PROVIDED,  HOWEVER,  that any such  termination  shall  occur if and only to the
extent that all  Obligations of such  Guarantor  under all of its guarantees of,
and under all of its pledges of assets which secure, Indebtedness of the Company
and the  other  Guarantors  shall  also  terminate  upon such  release,  sale or
transfer;  PROVIDED further,  that without limiting the foregoing,  any proceeds
received by the Company or any  Restricted  Subsidiary  of the Company from such
transaction  shall be applied as provided  in Section  4.10.  The Trustee  shall
deliver an  appropriate  instrument  evidencing  such  release upon receipt of a
request by the Company accompanied by an Officers' Certificate  certifying as to
the compliance  with this Section 11.5. Any Guarantor not released in accordance
with the first sentence of this Section 11.5, remains liable for the full amount
of  principal,  premium,  if any,  and interest on the Notes as provided in this
Article 11.

SECTION 11.6.  ADDITIONAL GUARANTORS.

          Any Person that was not a Guarantor on the Effective Date may become a
Guarantor  by  executing  and  delivering  to  the  Trustee  (a) a  supplemental
indenture in form and substance satisfactory to the Trustee, which subjects such
Person to the provisions (including, without limitation, the representations and
warranties  in this Article 11 and Article 10) of this  Indenture as a Guarantor
and (b) an Opinion of Counsel to the effect that such supplemental indenture has
been duly  authorized  and  executed by such Person and  constitutes  the legal,
valid,  binding  and  enforceable  obligation  of such  Person  (subject to such
customary  exceptions  concerning  creditors' rights and equitable principles as
may be  acceptable  to the Trustee in its  discretion).  The  Guarantee  of each
Person described in this Section 11.6 shall apply to all Notes whether executed,
authenticated  and delivered on, before or after the date such Person  becomes a
Guarantor.

SECTION 11.7.  GUARANTORS MAY CONSOLIDATE, ETC., ON CERTAIN TERMS.

                                       62
<PAGE>

          Nothing  contained  in this  Indenture  or in any of the  Notes  shall
prevent any  consolidation  or merger of a Guarantor with or into the Company or
another  Guarantor or shall  prevent any sale or conveyance of the property of a
Guarantor  as an entirety or  substantially  as an  entirety,  to the Company or
another Guarantor. Upon any such consolidation,  merger, sale or conveyance, the
Guarantee given by such Guarantor shall no longer have any force or effect.

SECTION 11.8.  SUCCESSORS AND ASSIGNS.

          This  Article  11  shall  be  binding  upon  each  Guarantor  and  its
successors  and assigns and shall  inure to the  benefit of the  successors  and
assigns of the Trustee and the Noteholders  and, in the event of any transfer or
assignment  of rights by any Holder or the  Trustee,  the rights and  privileges
conferred upon that party in this Indenture and in the Notes shall automatically
extend to and be vested in such transferee or assignee, all subject to the terms
and conditions of this Indenture.

SECTION 11.9.  WAIVER OF STAY, EXTENSION OR USURY LAWS.

          Each  Guarantor  covenants  (to the extent that it may lawfully do so)
that it will not at any time insist  upon,  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  such  Guarantor  from
performing its Guarantee as contemplated herein, wherever enacted, now or at any
time hereafter in force, or which may affect the covenants or the performance of
this  Indenture;  and (to the  extent  that it may  lawfully  do so)  each  such
Guarantor  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.

<PAGE>

          By the  execution  and delivery of this  Indenture or any amendment or
supplement hereto,  each of the Company and the Guarantors (i) acknowledges that
it has, by separate  written  instrument,  designated and appointed  Corporation
Service  Company  currently  located at Two World Trade Center,  Suite 8746, New
York, New York  10048-0203,  as its  authorized  agent upon which process may be
served in any suit,  action or  proceeding  with respect to,  arising out of, or
relating to, the Notes, this Indenture (other than an insolvency, liquidation or
bankruptcy  proceeding  or any other  proceeding  in the  nature of an in rem or
quasi in rem  proceeding),  that may be instituted in any Federal or state court
in the State of New York,  The City of New York,  the Borough of  Manhattan,  or
brought  under  Federal  or state  securities  laws or  brought  by the  Trustee
(whether in its  individual  capacity or in its capacity as Trustee  hereunder),
and acknowledges that Corporation Service Company has accepted such designation,
(ii) submits to the  jurisdiction of any such court in any such suit,  action or
proceeding,  and (iii) agrees that service of process upon  Corporation  Service
Company shall be deemed in every respect  effective  service of process upon the
Company in any such suit,  action or  proceeding.  Each of the  Company and each
Guarantor further agrees to take any and all action, including the execution and
filing of any and all such  documents  and  instruments  as may be  necessary to
continue such designation and appointment of Corporation Service Company in full
force and effect so long as this  Indenture  shall be in full force and  effect;
PROVIDED  that the  Company  and each  Guarantor  may and shall  (to the  extent
Corporation  Service  Company  ceases  to be  able  to be  served  on the  basis
contemplated  herein),  by  written  notice  to  the  Trustee,   designate  such
additional or alternative agents for service of process under this Section 12.15
that (i) maintains an office  located in the Borough of  Manhattan,  The City of
New York in the State of New York,  (ii) are either (a)  counsel for the Company
or the Guarantor,  as the case may be, or (b) a corporate  service company which
acts as agent for service of process for other persons in the ordinary course of
its  business  and (iii)  agrees  to act as agent  for  service  of  process  in
accordance with this Section 12.15.  Such notice shall identify the name of such
agent for  process  and the  address of such agent for process in the Borough of
Manhattan,  The City of New York,  State of New York.  Upon the  request  of any
Holder of a Note,  the Trustee  shall deliver such  information  to such Holder.
Notwithstanding the foregoing,  there shall, at all times, be at least one agent
for service of process for the Company and each  Guarantor  appointed and acting
in accordance with this Section 12.15.

          To the extent that the Company or any  Guarantor  has or hereafter may
acquire any immunity  from  jurisdiction  of any court or from any legal process
(whether through service of notice, attachment prior to judgment,  attachment in
aid of  execution,  execution  or  otherwise)  with  respect  to  itself  or its
property,  the Company or the Guarantor,  as the case may be, hereby irrevocably
waives such immunity in respect of its obligations  under this Indenture and the
Notes, to the extent permitted by law.

SECTION 12.16.   CURRENCY OF ACCOUNT; CONVERSION  OF  CURRENCY; FOREIGN EXCHANGE
                 RESTRICTIONS.

          (a) U.S.  dollars are the sole currency of account and payment for all
sums  payable  by the  Company  under or in  connection  with the  Notes or this
Indenture,  including  damages.  Any amount  received or recovered in a currency
other than U.S.  dollars  (whether as a result of, or of the  enforcement  of, a
judgment  or  order  of a  court  of  any  jurisdiction,  in the  winding-up  or
dissolution  of the Company or  otherwise) by any Holder of a Note in respect of
any sum  expressed  to be due to it from the  Company  will  only  constitute  a
discharge  to the  Company to the  extent of the U.S.  dollar  amount  which the
recipient  is able to purchase  with the amount so received or recovered in that
other  currency  on the  date of that  receipt  or  recovery  (or,  if it is not
practicable to make that purchase on that date, on the first date on which it is
practicable to do so). If that U.S.  dollar amount is less than the U.S.  dollar
amount  expressed to be due to the  recipient  under any Note,  the Company will
indemnify  it  against  any loss  sustained  by it as a result  as set  forth in
Section 12.16(b). In any event, the Company will indemnify the recipient against
the cost of making any such purchase. For the purposes of this Section 12.16, it
will be sufficient for the Holder of a Note to certify in a satisfactory  manner
(indicating  sources of information used) that it would have suffered a loss had
an actual purchase of U.S. dollars been made with the amount so received in that
other  currency  on the date of receipt or  recovery  (or, if a purchase of U.S.
dollars  on such date had not been  practicable,  on the first  date on which it
would have been  practicable,  it being  required  that the need for a change of
date be certified in the manner mentioned  above).  The indemnities set forth in
this Section 12.16 constitute a separate and independent cause of action,  shall
apply  irrespective of any indulgence  granted by any Holder of a Note and shall
continue in full force and effect despite any other  judgment,  order,  claim or
proof for a liquidated amount in respect of any sum due under any Note.

                                       67
<PAGE>

          (b) The Company  covenants  and agrees that the  following  provisions
shall  apply  to  conversion  of  currency  in the  case of the  Notes  and this
Indenture:

               (i) If for the purpose of obtaining judgment in, or enforcing the
          judgment of, any court in any country, it becomes necessary to convert
          into a currency (the  "judgment  currency") an amount due in any other
          currency (the "Base  Currency"),  then the conversion shall be made at
          the rate of exchange  (as defined in clause (v) below)  prevailing  on
          the  Business Day before the day on which the judgment is given or the
          order of enforcement is made, as the case may be (unless a court shall
          otherwise determine).

               (ii) If  there is a change  in the  rate of  exchange  prevailing
          between the Business Day before the day on which the judgment is given
          or an order of  enforcement is made, as the case may be (or such other
          date as a court  shall  determine),  and the  date of  receipt  of the
          amount due, the Company will pay such  additional (or, as the case may
          be,  such  lesser)  amount,  if any, as may be  necessary  so that the
          amount paid in the  judgment  currency  when  converted at the rate of
          exchange  prevailing on the date of receipt will produce the amount in
          the Base Currency originally due.

               (iii) In the event of the  winding-up  of the Company at any time
          while any amount or damages owing under the Notes and this  Indenture,
          or any  judgment or order  rendered in respect  thereof,  shall remain
          outstanding,  the Company will  indemnify  and hold the Holders of the
          Notes and the  Trustee  harmless  against  any  deficiency  arising or
          resulting from any variation in rates of exchange between (1) the date
          as  of  which  the  U.S.  Dollar  Equivalent  of  the  amount  due  or
          contingently  due under the Notes and this Indenture (other than under
          this  subsection  (b) (iii) is  calculated  for the  purposes  of such
          winding-up and (2) the final date for the filing of proofs of claim in
          such  winding-up.  For the purpose of this  subsection (b) (iii),  the
          final date for the filing of proofs of claim in the  winding-up of the
          Company  will be the date  fixed by the  liquidator  or  otherwise  in
          accordance with the relevant provisions of applicable law as being the
          latest  practicable date as at which liabilities of the Company may be
          ascertained for such winding-up  prior to payment by the liquidator or
          otherwise in respect thereof.

               (iv) The obligations  contained in subsections  (a), (b) (ii) and
          (b)  (iii)  of  this  Section  12.16  shall  constitute  separate  and
          independent  obligations  from the other Indenture  obligations of the
          Company,  shall give rise to separate and independent causes of action
          against  the  Company,  shall  apply  irrespective  of any  waiver  or
          extension  granted by any Holder of a Note or the Trustee or either of
          them from time to time and shall  continue  in full  force and  effect
          notwithstanding  any  judgment  or order or the filing of any proof of
          claim in the winding-up of the Company for a liquidated sum in respect
          of amounts due hereunder (other than under subsection (b) (iii) above)
          or under any such judgment or order.  Any such deficiency as aforesaid
          shall be deemed to  constitute  a loss  suffered by the Holders of the
          Note or the  Trustee,  as the case may be, and no proof or evidence of
          any actual loss shall be required by the Company or the  liquidator or
          otherwise or any of them. In the case of  subsection  (b) (iii) above,
          the amount of such deficiency shall not be deemed to be reduced by any
          variation in rates of exchange  occurring  between the said final date
          and the date of any liquidating distribution.

               (v)The term "rate(s) of exchange" shall mean the rate of exchange
          quoted  by  Reuters  at 10:00  a.m.  (New  York  City  time)  for spot
          purchases of the Base Currency with the judgment  currency  other than
          the Base  Currency  referred  to in  subsections  (b) (i) and (b) (ii)
          above and includes any premiums and costs of exchange payable.

          (c) In the event that on any payment date in respect of the Notes, any
restrictions or prohibition of access to the Brazilian  foreign  exchange market
exists,  the Company  agrees to pay all amounts  payable  under the Notes in the
currency  of  the  Notes  by all  reasonable  means  (which  shall  not  include
commencement  of legal  proceedings  against the  Central  Bank of Brazil or any
other  governmental  agency or authority or central  bank),  on any due date for
payment  under the Notes,  for the purchase of the  currency of such Notes.  All
costs and taxes payable in connection  with the  procedures  referred to in this
Section 12.16 shall be borne by the Company.

                        12% Senior Secured Notes due 2004

          Capitalized  terms used herein but not defined  will have the meanings
assigned to them in the Indenture referred to below unless otherwise indicated.

          1. INTEREST.

          On any of the first four Interest  Payment Dates  occurring  after the
date of the  Indenture,  interest  on the  Notes  shall,  at the  option  of the
Company,  be paid in kind  instead of in cash.  Upon such an event,  the Company
will issue to Holders of the Notes on any such Interest  Payment  Date,  and the
Trustee will  authenticate,  an additional Note substantially in the form hereof
registered in the name of such Holder and having a principal amount equal to the
amount of  interest  paid in kind on all of the  outstanding  Notes held by such
Holder on such  Interest  Payment  Date.  The Notes will mature on December  20,
2004. The Company  promises to pay interest on the principal amount of this Note
from  December  20,  1999  until   maturity.   The  Company  will  pay  interest
semi-annually on June 20 and December 20 of each year,  commencing  December 20,
2000, or if any such day is not a Business Day, on the next succeeding  Business
Day (each an "Interest Payment Date").  Interest on the Notes will accrue at the
rate of 12% per annum from the most recent date to which  interest has been paid
or, if no interest has been paid,  from December 20, 1999.  The Company will pay
interest  (including   post-petition   interest  in  any  proceeding  under  any
Bankruptcy Law to the extent that such interest is an allowed claim  enforceable
against the debtor under such Bankruptcy Law) on overdue  principal and premium,
if any,  from time to time on demand at the rate equal to 1% per annum in excess
of the then applicable  interest rate on this Note to the extent lawful; it will
pay  interest  (including  post-petition  interest in any  proceeding  under any
Bankruptcy  Law to the extent that such interest is an allowed claim against the
debtor under such Bankruptcy Law) on overdue  installments of interest  (without
regard to any applicable  grace periods) from time to time on demand at the same
rate to the extent  lawful.  Interest will be computed on the basis of a 360-day
year comprised of twelve 30-day months.

          2. METHOD OF PAYMENT.

          The Company will pay the principal  of, and premium,  and interest on,
the Notes on the dates and in the manner  provided  herein and in the Indenture.
Principal, premium, if any, and interest on, Certificated Notes will be payable,
and  Certificated  Notes  may be  presented  for  registration  of  transfer  or
exchange,  at the office or agency of the Company  maintained  for such purpose.
Principal  of, and premium and interest on,  Global Notes will be payable by the
Company  through the Trustee to the Depository in immediately  available  funds.
Holders of Certificated  Notes will be entitled to receive interest  payments by
wire  transfer in  immediately  available  funds if  appropriate  wire  transfer
instructions  have been  received  in  writing by the  Trustee  not less than 15
calendar  days  prior  to  the  applicable  Interest  Payment  Date.  Such  wire
instructions,  upon receipt by the Trustee,  will remain in effect until revoked
by such Holder.  If wire instructions have not been received by the Trustee with
respect to any Holder of a Certificated Note, payment of interest may be made by
check in  immediately  available  funds mailed to such Holder at the address set
forth upon the Register maintained by the Registrar.

          3. PAYING AGENT AND REGISTRAR.

          Initially,  Deutsche  Trust Bank Limited will act as principal  Paying
Agent,  and The Bank of New York, the Trustee under the  Indenture,  will act as
Registrar.  The Company may change any Paying Agent or  Registrar in  accordance
with  the  terms  of the  Paying  Agent  Agreement.  The  Company  or any of its
Subsidiaries may act in any such capacity,  PROVIDED,  HOWEVER, that none of the
Company,  its  Subsidiaries  or the  Affiliates of the foregoing will act (i) as
Paying Agent in connection with any redemption,  offer to purchase, discharge or
defeasance, as otherwise specified in the Indenture, and (ii) as Paying Agent or
Registrar if a Default or Event of Default has occurred and is continuing.

          4. INDENTURE.

                                      A-4
<PAGE>

          The Company  issued the Notes under an Indenture  dated as of July 20,
2000 (as such may be amended,  supplemented  or restated from time to time,  the
"Indenture") between the Company and the Trustee. The terms of the Notes include
those stated in the  Indenture and those made part of the Indenture by reference
to the  Trust  Indenture  Act  of  1939,  as  amended  (15  U.S.  Code  Sections
77aaa-77bbbb). The Notes are subject to all such terms, and Holders are referred
to the  Indenture  and such Act for a  statement  of such  terms.  The Notes are
senior  obligations  of the Company  ranking PARI PASSU in right of payment with
all existing and future senior Indebtedness of the Company and ranking senior in
right of payment to any future subordinated Indebtedness of the Company.

          5. OPTIONAL REDEMPTION.

          The Notes will be subject to  redemption at the option of the Company,
in whole or in part, upon not less than 30 nor more than 60 days' notice, at the
redemption  prices  (expressed  as  percentages  of principal  amount) set forth
below,  plus  accrued  and unpaid  interest  if any,  thereon to the  applicable
redemption  date,  if  redeemed  during the twelve  month  period  beginning  on
December 20 of the years indicated below:

                         Year                                 Percentage
                        ------                               ------------

                         2000                                 106.4375%

                         2001                                 104.2917%

                         2002                                 102.1458%

                         2003 and thereafter                  100.0000%

          6. MANDATORY REDEMPTION.

          Except as set forth in  paragraph  7 below,  the  Company  will not be
required to make  mandatory  redemption or sinking fund payments with respect to
the Notes.

          7. REPURCHASE AT OPTION OF HOLDER.

          (a) Upon a Change of Control,  the Company will be required to make an
offer to Holders to repurchase all or any part (equal to US$1,000 or an integral
multiple thereof) of each Holder's Notes at an offer price in cash equal to 101%
of the aggregate  principal  amount  thereof,  plus accrued and unpaid  interest
thereon to the date of  repurchase  as provided in, and subject to the terms of,
the Indenture.

          (b) If the Company or any Restricted Subsidiary  consummates any Asset
Sale,  the Company may be required,  subject to the terms and  conditions of the
Indenture, to utilize a certain portion of the proceeds received from such Asset
Sale to repurchase  Notes at a purchase  price equal to Net Proceeds Offer Price
on the Net Proceeds Purchase Date.

          8. DENOMINATIONS, TRANSFER, EXCHANGE.

          The Notes are in registered form without coupons in  denominations  of
US$1,000  and  integral  multiples  of  US$1,000.  The  transfer of Notes may be
registered  and  Notes  may be  exchanged  as  provided  in the  Indenture.  The
Registrar and the Trustee may require a Holder,  among other things,  to furnish
appropriate  endorsements  and transfer  documents and the Company may require a
Holder to pay any taxes and fees required by law or permitted by the  Indenture.
The Company need not exchange or register the transfer of any Note or portion of
a Note selected for  redemption,  except for the unredeemed  portion of any Note
being  redeemed in part.  Also, it need not exchange or register the transfer of
any Notes for a period of 15 calendar  days  before a  selection  of Notes to be
redeemed  or during the  period  between a record  date and the next  succeeding
Interest Payment Date.

                                      A-5
<PAGE>

          9. PERSONS DEEMED OWNERS.

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

          10. UNCLAIMED MONEY.

          If money for the payment of  principal,  premium or  interest  remains
unclaimed for one year, the Trustee and the Paying Agent will pay the money back
to the Company at its request. After that, all liability of the Trustee and such
Paying Agent with respect to such money will cease.

          11. DEFEASANCE PRIOR TO REDEMPTION OR MATURITY.

          Subject to certain conditions contained in the Indenture,  the Company
at any time may terminate some or all of its obligations under the Notes and the
Indenture  if  the  Company  deposits  with  the  Trustee  money  or  Government
Securities  sufficient to pay the principal  of,  premium,  and interest on, the
Notes to redemption or maturity, as the case may be.

          12. AMENDMENT, SUPPLEMENT AND WAIVER.

          Subject  to  certain  exceptions,  the  Indenture  or the Notes may be
amended or  supplemented  with the consent of the Holders of at least a majority
in principal amount of the Notes then  outstanding,  and any existing Default or
Event or Default or compliance  with any provision of the Indenture or the Notes
may be waived with the consent of the Holders of a majority in principal  amount
of the then outstanding Notes.  Without the consent of any Holder of a Note, the
Indenture  or the Notes may be amended or  supplemented  to cure any  ambiguity,
defect or inconsistency,  to provide for uncertificated  Notes in addition to or
in place of  Certificated  Notes, to provide for the assumption of the Company's
obligations  to Holders of Notes in case of a merger or  consolidation,  to make
any change that would provide any  additional  rights or benefits to the Holders
of the Notes or that  does not  adversely  affect  the  legal  rights  under the
Indenture of any such Holder,  or to comply with the  requirements of the SEC in
order to effect or maintain the  qualification of the Indenture under the TIA as
then in effect.

          13. DEFAULTS AND REMEDIES.

          An  "Event  of  Default"  occurs if one of the  following  shall  have
occurred and be continuing:

          (a) the  Company  defaults  in the  payment  when due of any  interest
payable with respect to the Notes at any time,  which  default  continues  for a
period of 30 calendar days;

          (b) the Company  defaults in payment  when due of the  principal of or
premium, if any, on the Notes at maturity,  upon repurchase (including,  without
limitation,  pursuant to a Change of Control Offer or an Asset Sale Offer), upon
acceleration, redemption or otherwise;

          (c) the granting by the Company or any  Restricted  Subsidiary  of any
Lien to secure  Indebtedness  in excess of  US$100,000  (other  than a Permitted
Lien);

          (d) the Company fails to comply with the  provisions of Sections 4.10,
4.14, 4.19 or 5.1 of the Indenture;

          (e) the Company  fails to comply with any of its other  agreements  in
this  Indenture or the Notes and such  failure  continues  for 30 calendar  days
after notice from the Trustee or Holders of at least 25% in aggregate  principal
amount of the Notes then outstanding;

          (f) the Company  defaults under any mortgage,  indenture or instrument
under which  there may be issued or by which  there may be secured or  evidenced
any  Indebtedness  for money  borrowed of the  Company or any of its  Restricted
Subsidiaries (or the payment of which is guaranteed by the Company or any of its
Restricted  Subsidiaries),  whether such Indebtedness or Guarantee now exists or
is created after the Effective Date, which default (i) is caused by a failure to

                                      A-6
<PAGE>

pay principal of or premium, if any, or interest on such Indebtedness  following
the expiration of the grace period provided in such  Indebtedness on the date of
such default (a "Payment  Default") or (ii) results in the  acceleration of such
Indebtedness  prior to its express  maturity  and, in each case,  the  principal
amount of any such Indebtedness, together with the principal amount of any other
such  Indebtedness  under which there has been a Payment Default or the maturity
of which has been so  accelerated,  aggregates  US$5,000,000  (or the equivalent
thereof at time of determination) or more;

          (g) the  Company or any of its  Restricted  Subsidiaries  fails to pay
final  non-appealable  judgments  rendered  against  the  Company  or any of its
Restricted Subsidiaries aggregating in excess of US$2,500,000 (or the equivalent
thereof at time of determination),  which judgments are not paid,  discharged or
stayed for a period of 60 calendar  days after such  judgments  become final and
non-appealable;

          (h) the Company or any Restricted  Subsidiary of the Company  pursuant
to or within the meaning of any  Bankruptcy  Law: (i) commences a voluntary case
or  proceeding,  (ii) consents to the entry of an order for relief against it in
an  involuntary  case or  proceeding,  (iii)  consents to the  appointment  of a
Custodian of it or for all or  substantially  all of its property,  (iv) makes a
general  assignment for the benefit of its creditors,  (v) admits in writing its
inability  to pay its  debts  generally  as they  become  due or (vi)  takes any
comparable action under any foreign laws relating to insolvency;

          (i) a court of competent  jurisdiction enters an order or decree under
any  Bankruptcy  Law  that:  (i)  is  for  relief  against  the  Company  or any
Significant Subsidiary of the Company in an involuntary case or proceeding, (ii)
appoints a Custodian of the Company or any Significant Subsidiary of the Company
or for all or substantially  all of its respective  properties,  or (iii) orders
the liquidation of the Company or any Significant  Subsidiary of the Company, or
any similar relief is granted under any foreign laws, and in each case the order
or decree remains unstayed and in effect for 60 calendar days;

          (j) (a) a default in the  observance or performance of any covenant or
agreement  contained in any Security  Document  which  default  continues for 20
calendar  days after  notice has been given to the Company by the Trustee or the
holders of at least 25% in principal amount of the outstanding Notes, or (b) for
any reason other than the  satisfaction in full and discharge of all obligations
secured  thereby or any action or inaction  of the Trustee or the Holders  after
receiving  notice of the  requirement  to take any such action from the Company,
any of the Security  Documents ceases to be in full force and effect (other than
in  accordance  with its  respective  terms),  or any of the Security  Documents
ceases to give the Trustee the Liens, rights, powers and privileges purported to
be created thereby,  or any Security  Document is declared null and void, or the
Company or any of its  Restricted  Subsidiaries  denies  any of its  obligations
under any  Security  Document,  in each  case with  respect  to  Collateral  the
aggregate value of which is in excess of US$100,000,  or the Collateral  becomes
subject to one or more Liens other than  Permitted  Liens  securing  one or more
obligations in excess of US$100,000 in the aggregate; or

          (k) any  Guarantee  is declared  null and void or ceases to be in full
force and effect  (except as permitted  under this  Indenture)  or any Guarantor
shall deny or disaffirm its obligations under its Guarantee.

          Notwithstanding  the  foregoing,  if an Event of Default  specified in
clause  (f) above  occurs  and is  continuing,  such  Event of  Default  and all
consequences  thereof  (including,   without  limitation,  any  acceleration  or
resulting  payment  default) will be annulled and rescinded,  automatically  and
without  any  action by the  Trustee or the  Holders  of the  Notes,  if (i) the
Indebtedness  that is the subject of such Event of Default has been  repaid,  or
(ii) the default  relating to such  Indebtedness is waived or cured (and if such
Indebtedness has been accelerated, when the holders thereof have rescinded their
declaration of acceleration in respect of such Indebtedness).

          In the case of any Event of Default occurring by reason of any willful
action (or  inaction)  taken (or not taken) by or on behalf of the Company  with
the intention of avoiding payment of the premium that the Company would have had
to pay if the  Company  then had  elected  to redeem the Notes  pursuant  to the
optional  redemption  provisions of this Indenture,  an equivalent  premium will
also become and be  immediately  due and payable to the extent  permitted by law
upon the acceleration of the Notes.

                                      A-7
<PAGE>

          If any Event of Default  (other than an Event of Default  specified in
clause  (h) or (i) above  occurs  and is  continuing),  then the  Trustee or the
Holders of at least 25% in  principal  amount of the then  outstanding  Notes by
written  notice to the Company and the Trustee may declare the unpaid  principal
of,  and  any  accrued  interest  on,  all  the  Notes  to be  due  and  payable
immediately.  If any Event of Default with  respect to the Company  specified in
clause (h) or (i) hereof  occurs with  respect to the Company,  any  Significant
Subsidiary of the Company or any group of Restricted Subsidiaries of the Company
that, taken together,  would constitute a Significant Subsidiary of the Company,
all outstanding  principal and interest on the Notes will be immediately due and
payable  without any  declaration or other act on the part of the Trustee or any
Holder.  The  Holders  of a  majority  in  principal  amount of the  Notes  then
outstanding, by written notice to the Trustee and to the Company, may rescind an
acceleration  (except  an  acceleration  due  to a  default  in  payment  of the
principal  of, or premium or  interest  on, any of the Notes) if the  rescission
would not conflict  with any  judgment or decree and if all  existing  Events of
Default (except nonpayment of principal,  premium, interest that have become due
solely because of the acceleration) have been cured or waived.

          Subject to the preceding paragraph,  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 any payment  due, or to enforce the  performance  of any
provision,  under the Notes,  this  Indenture  or the  Security  Documents.  The
Trustee  may refuse to enforce  the  Indenture  or the Notes  unless it receives
indemnity or security  reasonably  satisfactory  to it. Holders of Notes may not
enforce the Indenture or the Notes except as provided in the Indenture.  Subject
to certain  limitations,  Holders of a majority in principal amount of the Notes
may direct the Trustee in its  exercise  of any trust or power.  The Trustee may
withhold from Holders of the Notes notice of any continuing  Default or Event of
Default  (except  under  clauses  (a)  or  (b)  above)  if  it  determines  that
withholding notice is in their interest.

          14. 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 any
Affiliate  of the  Company  with the same  rights  it would  have if it were not
Trustee.  However,  in the  event  that the  Trustee  acquires  any  conflicting
interest (as such term is defined in TIA Section 310(b)), it must eliminate such
conflict within 90 calendar days, apply to the SEC for permission to continue as
trustee (to the extent permitted under TIA Section 310(b)) or resign.  Any Agent
may do the same with like rights and duties.

          15. NO  PERSONAL  LIABILITY  OF  DIRECTORS,  OFFICERS,  EMPLOYEES  AND
OTHERS.

          No past, present or future director, officer, employee,  incorporator,
partner or stockholder of either of the Company or any of its  Subsidiaries,  as
such,  will  have  any  liability  for any  obligations  of the  Company  or its
Subsidiaries  under the Notes,  the Security  Documents,  the  Guarantees or the
Indenture  or for any  claim  based  on,  in  respect  of or by  reason  of such
obligations or their creation.  Each Holder of a Note by accepting a Note waives
and  releases  all  such  liability.  The  waiver  and  release  are part of the
consideration for issuance of the Notes and the Guarantees.

          16. AUTHENTICATION.

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

          17. ABBREVIATIONS.

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

          18. CUSIP NUMBERS.

                                      A-8
<PAGE>

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

          19. GOVERNING LAW.

PAYMENT -           (c)  Additional  Rent  shall  be  paid  and   adjusted  with
ADDITIONAL RENT     reference to a fiscal period of twelve (12) calendar  months
                    ("Fiscal Period"), which shall be a calendar year unless the

                    Period which is not a calendar year by written notice to the
                    Tenant.

                           The  Landlord  shall  advise the Tenant in writing of
                    its  estimate  of the  Additional  Rent to be payable by the

                    Fiscal  Period,  as the case may be,  if  applicable  at the
                    commencement  or end of the term or  because  of a change in
                    Fiscal Period) which commenced upon the commencement date of
                    the Term and for each  succeeding  Fiscal  Period  or broken
                    portion  thereof  which  commences  during  the  Term.  Such
                    estimate  shall in every case be a reasonable  estimate and,
                    if  requested  by  the  Tenant,   shall  be  accompanied  by
                    reasonable  particulars  of  the  manner  in  which  it  was
                    calculated.  The Additional Rent payable by the Tenant shall
                    be paid in equal monthly installments in advance at the same
                    time as payment of Basic Rent is due hereunder  based on the
                    Landlord's  estimate as  aforesaid.  From time to time,  the
                    Landlord may re-estimate,  on a reasonable basis, the amount
                    of Additional  Rent for any Fiscal Period or broken  portion
                    thereof,  in which case the Landlord shall advise the Tenant
                    in writing  of such  re-estimate  and fix new equal  monthly
                    installments for the remaining balance of such Fiscal Period
                    or broken portion thereof. After the end of each such Fiscal
                    Period or broken portion  thereof the Landlord shall provide
                    the Tenant with a statement  of the actual  Additional  Rent
                    payable in respect of such Fiscal  Period or broken  portion
                    thereof  and a  calculation  of the  amounts  by  which  the
                    Additional  Rent  payable by the  Tenant  exceeds or is less
                    than (as the case may be) the aggregate installments paid by
                    the  Tenant on account of  Additional  Rent for such  Fiscal
                    Period.

                           Within thirty (30) days after the  submission of such
                    statement  either the Tenant  shall pay to the  Landlord any
                    amount by which the amount found  payable by the Tenant with
                    respect  to such  Fiscal  Period or broken  portion  thereof
                    exceeds the aggregate of the monthly  payments made by it on
                    account  thereof during such Fiscal Period or broken portion
                    thereof,  or the Landlord shall pay to the Tenant any amount
                    by which the amount found  payable as aforesaid is less than
                    the aggregate of such monthly payments.

RECOVERY OF RENT    (d) In this Lease "Rent" means all amounts  required
                    to be paid by the Tenant  pursuant  to this Lease  including
                    without limitation Basic Rent and Additional Rent.

                    accruing  from day to day,  and for an  irregular  period of

                    apportioned  and  adjusted  by the  Landlord  for the Fiscal
                    Periods of the Landlord in which the tenancy  created hereby
                    commences and expires.  Where the  calculation of Additional
                    Rent for a period cannot be made until after the termination
                    of  this  Lease,   the  obligation  of  the  Tenant  to  pay
                    Additional  Rent shall  survive the  termination  hereof and
                    Additional  Rent for such  period  shall be  payable  by the
                    Tenant upon demand by the Landlord. If the Term commences or
                    expires on any day other than the first or the last day of a
                    month, Basic Rent and Additional Rent for such fraction of a
                    month shall be  apportioned  and adjusted as  aforesaid  and
                    paid by the  Tenant  on the  commencement  date of the Term.

                    Dispute Notice shall set out in reasonable detail the reason
                    why  such  statement,  document  or  writing  is in error or
                    otherwise should not be binding on the Tenant. If the Tenant
                    disputes the amount of the Additional Rent as aforesaid, and

                    (ii)  not  to  permit  or  suffer  any  substance  which  is
                    hazardous  or  is  prohibited,   restricted,   regulated  or
                    controlled under any  Environmental Law to be present at, on
                    or in the Leased Premises,  excluding normal office supplies
                    in  customary  quantities,  unless it has received the prior
                    written  consent  of  the  Landlord  which  consent  may  be
                    arbitrarily withheld;

 RULES AND          (f)  to observe  and  perform,  and to cause its  employees,
 REGULATIONS        invitees and others over whom the Tenant can reasonably
                    be expected to exercise control to observe and perform,  the

                    mortgage  or encumber  this Lease or the Leased  Premises or
                    any part  thereof,  or suffer or permit the occupation of
                    all or any part  thereof  by others  (each of
                    which is a "Transfer")  without the prior written consent of
                    the Landlord,  which  consent the Landlord  covenants not to
                    withhold  unreasonably (i) as to any assignee,  subtenant or
                    occupant  (the   "Transferee")  who  is  in  a  satisfactory
                    financial  condition,  agrees to use the Leased Premises for
                    those  purposes  permitted  hereunder,  and  (ii)  as to any
                    portion  of the Leased  Premises  which,  in the  Landlord's
                    reasonable  judgment,  is a proper and rational  division of
                    the  Leased  Premises,  subject to the  Landlord's  right of
                    termination  arising under this paragraph.  This prohibition
                    against a  Transfer  shall  not be  construed  to  include a
                    prohibition  against any  Transfer by  operation  of law. As
                    used herein  "Transfer"  shall not include any assignment by
                    Tenant to a  subsidiary  of the  Tenant so long as  Sections
                    7(d) and 7(e) hereof are  complied  with by the Tenant,  and

                    inconsistent  with the Lease,  and the  acceptance  of which
                    would  not  breach  any  provision  of  this  Lease  if this
                    paragraph  is  complied   with  and  which  the  Tenant  has
                    determined  to  accept  subject  to  this  paragraph   being
                    complied with, and

                           (ii) it shall have first  requested  and obtained the
                    consent in  writing  of the  Landlord  thereto  pursuant  to
                    Section 7(a).

                    Any request for consent shall be in writing and  accompanied
                    by a copy of the offer  certified  by the  Tenant to be true
                    and  complete,  and the Tenant shall furnish to the Landlord

                    requested  by  the   Landlord  as  to  the   responsibility,
                    financial standing and business of the proposed  Transferee.
                    Notwithstanding  the provisions of sub-paragraph (a), within
                    twenty (20) days after the  receipt by the  Landlord of such
                    request  for  consent  and  of  all  information  which  the
                    Landlord shall have requested hereunder,  the Landlord shall
                    have the right upon written notice of termination  submitted
                    to the  Tenant,  if the  request is to assign  this Lease or
                    sublet  the whole of the  Leased  Premises,  to  cancel  and
                    terminate this Lease,  or if the request is to sublet a part
                    of the Leased  Premises  only, to cancel and terminate  this
                    Lease  with  respect  to such  part,  in  each  case as of a
                    termination   date  to  be   stipulated  in  the  notice  of
                    termination  which shall be not less than sixty (60) days or
                    more than  ninety  (90) days  following  the  giving of such
                    notice.  In such event the Tenant shall  surrender the whole
                    or part,  as the  case may be,  of the  Leased  Premises  in
                    accordance  with such notice of  termination  and Basic Rent
                    and  Additional  Rent shall be  apportioned  and paid to the
                    date of surrender and, if a part only of the Leased Premises
                    is  surrendered,  Basic Rent and Additional Rent shall after
                    the date of surrender abate proportionately. If such consent
                    shall be given the Tenant  shall  effect the  Transfer  only
                    upon  the  terms  set  out in  the  offer  submitted  to the
                    Landlord as aforesaid and not  otherwise.  Any consent shall
                    be given without  prejudice to the  Landlord's  rights under
                    the Lease and shall be limited to the particular Transfer in
                    respect  of which it was given and shall not be deemed to be
                    an  authorization  for or  consent  to any  further or other
                    Transfer.

EXCESS  TRANSFER    (c) In the  event the   Landlord  consents to any  Transfer,

                    "Excess  Transfer  Rent"),  if  any,  as  Rent.  The  Excess
                    Transfer  Rent  shall be  determined  in accordance with the
                    following:

                    It  shall  be a  condition  to  Landlord's  consent  to  any
                    subleasing,  assignment or other  transfer of part or all of
                    Tenant's interest in the Premises  (hereinafter  referred to
                    as  a  "Transfer")  that  upon  Landlord's  consent  to  any
                    Transfer, Tenant shall pay and continue to pay as Additional

                    assignment,  and/or the value of any stock warrants or stock
                    options  given  as   consideration   for  an  assignment  or
                    subletting,  and/or  any  consideration  or  money  paid  in

                    and reasonable  attorney's fees to effect such assignment or
                    subletting.

                    transfer  effective  voting  control of the  corporation  to
                    others than the shareholder or shareholders having effective
                    voting control of the corporation  immediately prior to such
                    transfer or  issuance,  shall be deemed for all  purposes of
                    this  paragraph  7 to  be a  Transfer  and,  accordingly,  a
                    violation of this paragraph 7 respecting  assignment of this
                    Lease  unless the prior  written  consent of the Landlord is
                    first obtained,  and the Landlord shall have all of the same
                    rights in respect  thereof as though  any such  transfer  or
                    issuing  of shares or  proposed  transferring  or issuing of
                    shares were a Transfer.  The  Landlord  shall have access at
                    all times to the corporate  books and records of the Tenant,

                    or its  representatives  upon request,  for  inspection  and
                    copying  at all times in order to  ascertain  whether or not
                    there has at any time  during  the Term of this Lease been a
                    transfer or issuing of shares  sufficient  to  constitute  a
                    change in the effective  voting control of the Tenant.  This
                    subparagraph  7 (f) shall not apply to the Tenant if and for
                    so long as the  Tenant is a  corporation  whose  shares  are
                    listed and traded on any recognized stock exchange in Canada
                    or the United  States,  and shall not apply to a corporation
                    that  controls  the Tenant if such  controlling  corporation
                    itself is a  corporation  with a net worth of at least Fifty

                    (g) Notwithstanding  anything in this Lease to the contrary,
                    the  Tenant  shall  not be  permitted  without  the  written
                    consent of the Landlord pursuant to this Section 7 to effect
                    a  Transfer  to  tenants  currently  occupying  space in the
                    Property.  Landlord  consents  to a sublease  to the current
                    tenant,  Nick Talesfore,  dba Talesfore Design,  pursuant to
                    Section  7 (a),  provided  that  Tenant  complies  with  the

                    this  paragraph but for  the  exclusion therefrom of defects
                    not   sufficient to  impair the  Tenant's use of  the Leased
                    Premises while using them in a  manner  consistent with this
                    Lease. The  Landlord  may enter the Leased  Premises  at all
                    reasonable  times and  view the  condition  thereof  and the
                    Tenant  covenants with  the Landlord to repair, maintain and
                    keep  the  Leased Premises  in  good  and substantial repair
                    according  to  notice  in  writing, reasonable wear and tear
                    excepted. If  the  Tenant shall  fail to repair as aforesaid
                    after  reasonable  notice  to do so, the Landlord may effect
                    the  repairs  and  the Tenant  shall pay the reasonable cost
                    thereof to the Landlord on demand. The Tenant covenants with
                    the Landlord that the Tenant  will   at the  expiration   of
                    the  Term  or sooner termination thereof peaceably surrender
                    the   Leased   Premises  and  appurtenances  in   good   and
                    substantial  repair and  condition, reasonable wear and tear
                    excepted.

Indemnification     (d) If any  part  of the  Property  becomes  out of  repair,
                    damaged or destroyed  through the  negligence  of, or misuse
                    by, the Tenant or its employees,  agents, invitees or others
                    under its  control,  the Tenant  shall pay the  Landlord  on
                    demand the expense of repairs or replacements, including the
                    Landlord's   reasonable   administration   charge   thereof,
                    necessitated by such negligence or misuse.

DAMAGE AND          (e)    It is agreed between the Landlord and the Tenant
DESTRUCTION                that:

                           (i) in the event of damage to the  Property or to any
                           part  thereof,  if in the  reasonable  opinion of the
                           Landlord the damage is such that the Leased  Premises
                           or any  substantial  part  thereof  is  rendered  not
                           reasonably capable of use and occupancy by the Tenant
                           for the  purposes of its  business  for any period of
                           time in excess of ten (10) days, then

                                  (1)   unless  the  damage  was  caused  by the
                                        fault or negligence of the Tenant or its
                                        employees,  agents,  invitees  or others
                                        under  its  control,  from  the  date of
                                        occurrence  of the  damage and until the
                                        Leased  Premises  are  again  reasonably
                                        capable   for  use  and   occupancy   as
                                        aforesaid,  the Rent payable pursuant to
                                        this Lease shall abate from time to time
                                        in  proportion  to the  part or parts of

                                        the  Leased   Premises  not   reasonably
                                        capable of such use and occupancy, and

                                  (2)   unless  this  Lease  is   terminated  as
                                        hereinafter  provided,  the  Landlord or
                                        the Tenant as the case may be (according
                                        to the  nature of the  damage  and their
                                        respective   obligations  to  repair  as
                                        provided in sub-paragraphs  (a), (b) and
                                        (c) of this paragraph) shall repair such
                                        damage  with all  reasonable  diligence,
                                        but to the  extent  that any part of the
                                        Leased   Premises   is  not   reasonably
                                        capable  of such  use and  occupancy  by
                                        reason  of damage  which  the  Tenant is
                                        obligated  to  repair   hereunder,   any
                                        abatement  of Rent to which  the  Tenant
                                        would  otherwise  be entitled  hereunder
                                        shall not extend  later than the time by
                                        which, in the reasonable  opinion of the
                                        Landlord, repairs by the Tenant ought to
                                        have  been  completed  with   reasonable
                                        diligence;

                             (ii) if the damage is such that the Leased Premises
                           are rendered  untenantable,  in whole or in part, and
                           if, in the opinion of the Landlord, the damage cannot
                           be  repaired  with  reasonable  diligence  within one
                           hundred and eighty  (180) days from the  happening of
                           the damage, then the Landlord may, within thirty (30)
                           days  after the date of the  damage,  terminate  this
                           Lease by  notice  to the  Tenant.  Upon the  Landlord
                           giving such notice, this Lease shall be terminated as
                           of the date of the  damage and the Rent and all other
                           payments  for  which the  Tenant is liable  under the
                           terms of this Lease shall be apportioned  and paid in
                           full  to the  date  of  the  damage.  If  the  Leased
                           Premises are not  repaired  within 180 days after the
                           date of damage,  the Tenant may, within 30 days after
                           such 180th day, terminate this Lease by notice to the
                           Landlord.  Upon the Tenant  giving such notice,  this
                           Lease  shall be  terminated  as of the date of damage
                           and the Rent and all  other  payments  for  which the
                           Tenant is liable  under the terms of this Lease shall
                           be  apportioned  and  paid  in  full  to the  date of
                           damage;

                           (iii) the Landlord shall not be required to use plans
                           and  specifications  and working drawings used in the
                           original  construction of the Building and nothing in
                           this  Section  requires  the  Landlord to rebuild the
                           Building  in the  condition  and state  that  existed
                           before the damage, but the Building, as rebuilt, will
                           have  reasonably  similar  facilities and services to
                           those in the Building prior to the damage; and

                           (iv) if  premises  whether  of the  Tenant  or  other
                           tenants of the Property  comprising  in the aggregate
                           half or more of the total  number  of square  feet of
                           rentable  office area in the Property or half or more
                           of the total number of square feet of rentable office
                           area in the Building (as  determined by the Landlord)
                           or portions of the Property  which  affect  access or
                           services essential thereto, are substantially damaged
                           or  destroyed  by any cause and if in the  reasonable
                           opinion of the Landlord the damage cannot  reasonably
                           be repaired  within one hundred and eighty (180) days
                           after the occurrence thereof,  then the Landlord may,
                           by written  notice to the Tenant given within  thirty
                           (30) days  after  the  occurrence  of such  damage or
                           destruction,  terminate  this  Lease,  in which event
                           neither the Landlord nor the Tenant shall be bound to
                           repair as provided in sub-paragraphs  (a) (b) and (c)
                           of this  paragraph,  and  the  Tenant  shall  instead
                           deliver up possession  of the Leased  Premises to the
                           Landlord with reasonable  expedition but in any event
                           within sixty (60) days after  delivery of such notice
                           of  termination,  and Rent shall be  apportioned  and
                           paid  to  the  date  upon  which   possession  is  so
                           delivered up (but  subject to any  abatement to which
                           the Tenant may be entitled  under  sub-paragraph  (e)
                           (i) of this paragraph).

                           9. INSURANCE AND LIABILITY

LANDLORD'S          (a) The  Landlord  shall take out and keep in force  during
INSURANCE           the Term insurance  with  respect to the  Property    except
                    for the  "Leasehold Improvements" (as hereinafter defined)
                    in the Leased Premises.  The insurance to be
                    maintained by the Landlord shall be in respect of perils and
                    in amounts  and on terms and  conditions  which from time to
                    time are  insurable  at a  reasonable  premium and which are
                    normally insured by reasonable  prudent owners of properties
                    similar to the Property, all as from time to time determined
                    at reasonable  intervals by insurance  advisors  selected by
                    the Landlord, and whose opinion shall be conclusive.  Unless
                    and until the insurance  advisors  shall state that any such
                    perils  are not  customarily  insured  against  by owners of
                    properties similar to the Property, the perils to be insured
                    against by the Landlord shall include,  without  limitation,
                    public liability,  boilers and machinery,  fire and extended
                    perils and may include at the option of the Landlord  losses
                    suffered by the Landlord in its capacity as Landlord through
                    business interruption. The insurance to be maintained by the
                    Landlord shall contain a waiver by the insurer of any rights
                    of  subrogation  or  indemnity or any other claim over which
                    the insurer might  otherwise be entitled  against the Tenant
                    or the agents or employees of the Tenant.

TENANT'S            (b) The Tenant  shall take out and keep in force during the
INSURANCE           Term:

                    (i)    comprehensive general public  liability  insurance
                           all on an  occurrence basis  with  respect  to the
                           business carried on in or from the Leased Premises
                           and the Tenant's use and occupancy of the

                                      9
<PAGE>

                            Leased Premises and of any other part of the
                            Property, with coverage for any one occurrence or
                            claim of not less than Five Million Dollars
                            ($5,000,000) or such other amount as the Landlord
                            may reasonably require upon not less than one (1)
                            month notice at any time during the Term, which
                            insurance shall include the Landlord as a named
                            insured and shall contain a cross liability
                            clause protecting the Landlord in respect of claims
                            by the Tenant as if the Landlord were separately
                            insured; and,

                           (ii)   insurance  against  such  other  perils and in
                                  such  amounts as the Landlord may from time to
                                  time  reasonably  require  upon not less  than
                                  ninety  (90)  days'   written   notice,   such
                                  requirement  to be made on the basis  that the
                                  required  insurance  is  customary at the time
                                  for similarly  situated  tenants of properties
                                  similar to the Property.

                    All insurance  required to be maintained by the Tenant shall
                    be on terms and with insurers  satisfactory to the Landlord.
                    Each policy  shall  contain:  (A) a waiver by the insurer of
                    any rights of  subrogation  or  indemnity or any other claim
                    over to  which  the  insurer  might  otherwise  be  entitled
                    against  the  Landlord  or the  agents or  employees  of the
                    Landlord,   (B)  a  cross   liability   clause  and  (C)  an
                    undertaking  by the insurer that no material  change adverse
                    to the  Landlord or the Tenant will be made,  and the policy
                    will not lapse or be  canceled,  except  after not less than
                    thirty  (30) days'  written  notice to the  Landlord  of the
                    intended  change,  lapse or  cancellation.  The Tenant shall
                    furnish to the  Landlord,  if and whenever  requested by it,
                    certificates or other  evidences  acceptable to the Landlord
                    as to the insurance from time to time effected by the Tenant
                    and its  renewal or  continuation  in force,  together  with
                    evidence  as  to  the  method  of   determination   of  full
                    replacement  cost of the  Tenant's  Leasehold  Improvements,
                    trade fixtures, furniture and equipment, and if the Landlord
                    reasonably concludes that the full replacement cost has been
                    underestimated,  the Tenant shall forthwith  arrange for any
                    consequent increase in coverage required under sub-paragraph
                    (b). If the Tenant shall fail to take out, renew and keep in
                    force such insurance,  or if the evidences  submitted to the
                    Landlord  are  unacceptable  to the  Landlord  (or  no  such
                    evidences  are  submitted  within a reasonable  period after
                    request  therefor by the  Landlord),  then the  Landlord may
                    give to the Tenant written notice requiring  compliance with
                    this  sub-paragraph and specifying the respects in which the
                    Tenant is not then in compliance with this sub-paragraph. If
                    the Tenant does not within  forty-eight  (48) hours  provide
                    appropriate  evidence of compliance with this sub-paragraph,
                    the Landlord may (but shall not be obligated to) obtain some

                           re-letting of the Leased  Premises which has occurred
                           at the time of the  aforesaid  demand by the Landlord
                           to  the  Tenant.  The  Tenant  agrees  to  pay to the
                           Landlord the  difference  between  items (i) and (ii)
                           above for the period  through and  including the date
                           on which this Lease would have  expired if it had not
                           been  terminated.  The Landlord  shall be entitled to
                           any excess with no credit to the Tenant. The Landlord
                           may,  in its  sole  discretion,  make  demand  on the
                           Tenant as aforesaid on any one or more occasions, and
                           any  suit   brought  by  the   Landlord   to  enforce
                           collection of such difference for any one month shall
                           not  prejudice  the  Landlord's  right to enforce the
                           collection of any difference for any subsequent month
                           or months. In addition to the foregoing,  and without
                           regard to  whether  this  Lease has been  terminated,
                           Tenant shall pay to the  Landlord all costs  incurred
                           by  the  Landlord,  including  reasonable  attorneys'
                           fees,   with   respect  to  any   lawsuit  or  action
                           instituted  or taken by the  Landlord  to enforce the
                           provisions  of this  Lease.  The  Tenant's  liability
                           shall survive the institution of summary  proceedings
                           and the issuance of any warrant hereunder.

                           If the Landlord  determines that it is  impracticable
                           or  extremely  difficult  to fix the actual  damages,
                           then,  as an  alternative  to the remedy set forth in
                           the preceding  paragraph,  the Tenant will pay to the
                           Landlord  on  demand,  liquidated  and  agreed  final
                           damages  for  the  Tenant's  default   calculated  in
                           accordance  with this paragraph.  Liquidated  damages
                           hereunder  shall be an  amount  equal to the  present
                           value at a rate of six percent  (6%) per annum of the
                           excess,  if any, of (i) all Rent  payable  under this
                           Lease from the date of such  demand for what would be
                           the then  unexpired Term of this Lease in the absence
                           of such  termination  over (ii) the then fair  market
                           rental value of the Leased Premises (as determined by
                           the  Landlord).  If any law shall  limit  the  amount
                           agreed upon,  the  Landlord  shall be entitled to the
                           maximum  amount  allowable  under  such law.  Nothing
                           herein shall be construed to affect or prejudice  the
                           Landlord's right to prove, and claim in full,  unpaid
                           rent accrued prior to termination of this Lease. Upon
                           termination  of this  Lease and the Term,  the Tenant
                           shall immediately deliver up possession of the Leased
                           Premises  to  the  Landlord,  and  the  Landlord  may
                           forthwith re-enter and take possession of them.

                    (c)    The Tenant  shall pay to the  Landlord  on demand all
                           costs and expenses, including lawyers' fees, incurred
                           by the Landlord in enforcing  any of the  obligations
                           of the Tenant under this Lease.

                              ADDITIONAL PROVISIONS

COMMON AREAS        11.    The Tenant  acknowledges and  agrees that  the common
                    areas of  the  Property  shall  at  all  times  be   subject
                    to the  exclusive  management  and control of the  Landlord.
                    Without limiting the generality of the foregoing, the Tenant
                    specifically  acknowledges  and agrees that the Landlord may
                    temporarily  close or restrict the use of all or any part of
                    the common  areas of the  Property in an  emergency,  or for
                    security or crowd control  purposes,  to facilitate  tenants
                    moving  in or out of the  building,  or for the  purpose  of
                    making  repairs,  alterations or  renovations.  The Landlord
                    agrees not to  permanently  alter such  common  areas in any
                    manner  which  would  deny  reasonable  access to the Leased
                    Premises.  In the  event of any such  temporary  closure  or
                    restriction  of use or if  changes  are made to such  common
                    areas by the Landlord,  the Landlord shall not be subject to
                    any  liability  nor shall  the  Tenant  be  entitled  to any
                    compensation or any diminution or abatement of Rent and such
                    closures,  restriction and changes shall not be deemed to be
                    a  constructive  or  actual  eviction  or a  breach  of  the
                    Landlord's covenant for quiet enjoyment.

                    12.      [Intentionally omitted]

SUBORDINATION  AND  13. This Lease and all rights of the Tenant hereunder are
ATTORNMENT          subject and subordinate to all underlying leases and
                    charges, or mortgages now or hereafter existing (including
                    charges, and mortgages by way of debenture, note, bond,
                    deeds of trust and mortgage and all instruments supplemental
                    thereto) which may now or hereafter affect the Property or
                    any part thereof and to all renewals, modifications,
                    consolidations, replacements and extensions thereof provided
                    the lessor, chargee, mortgagee or trustee agrees to accept
                    this Lease if not in default; and in recognition of the
                    foregoing the Tenant agrees that it will, whenever
                    requested, attorn to such lessor, chargee, mortgagee as a
                    tenant upon all the terms of this Lease. The Tenant agrees
                    to execute promptly whenever requested by the Landlord or by
                    the holder of any such lease, charge, or mortgage an
                    instrument of subordination or attornment as may be required
                    of it.

CERTIFICATES        14.  The  Tenant  agrees  that it  shall  promptly  whenever
                    requested  by the  Landlord  from time to time  execute  and
                    deliver to the Landlord, and if required by the Landlord, to
                    any lessor, chargee, or mortgagee (including any trustee) or
                    other person  designated by the Landlord,  an acknowledgment
                    in writing as to the then status of this Lease, including as
                    to whether it is in full force and  effect,  is  modified or
                    unmodified,  confirming  the Rent payable  hereunder and the
                    state of the accounts between  Landlord and the Tenant,  the
                    existence  or  non-existence  of  defaults,  and  any  other
                    matters  pertaining  to this Lease as to which the  Landlord
                    shall request an acknowledgment.

INSPECTION OF AND   15. The Landlord shall be permitted at any time and from
ACCESS TO THE       time to time to enter and to have its authorized agents,
LEASED  PREMISES    employees and contractors enter the Leased Premises for the
                    purposes of inspection, window cleaning, maintenance,
                    providing janitor service, making repairs, alterations or
                    improvements to the Leased Premises or the Property, or to
                    have access to utilities and services (including all ducts
                    and access panels (if any), which the Tenant agrees not to
                    obstruct) and the Tenant shall provide free and unhampered
                    access for the purpose, and shall not be entitled to
                    compensation or any diminution or abatement of Rent for any
                    inconvenience, nuisance or discomfort caused thereby. The
                    Landlord and its authorized agents and employees shall be
                    permitted entry to the Leased Premises for the purpose of
                    exhibiting them to prospective tenants. The Landlord in
                    exercising its rights under this paragraph shall do so to
                    the extent reasonably necessary so as to minimize
                    interference with the Tenant's use and enjoyment of the
                    Leased Premises provided that in an emergency the Landlord
                    or persons authorized by it may enter the Leased Premises
                    without regard to minimizing interference.

DELAY               16. Except as herein otherwise  expressly  provided,  if and
                    whenever  and to the extent that either the  Landlord or the
                    Tenant  shall be  prevented,  delayed or  restricted  in the
                    fulfillment  of any  obligation  hereunder in respect of the
                    supply or provision of any service or utility, the making of
                    any repair,  the doing of any work or any other thing (other
                    than the payment of moneys required to be paid by the Tenant
                    to the Landlord hereunder) by reason of:

                           (a)    strikes or work stoppages;
                           (b)    being unable to obtain any material, service,
                                  utility or labor required to fulfill such
                                  obligation;
                           (c)    any  statute,   law  or   regulation   of,  or
                                  inability  to obtain any  permission  from any
                                  government     authority     having     lawful
                                  jurisdiction    preventing,     delaying    or
                                  restricting such fulfillment; -or-
                           (d)    other unavoidable occurrence,

                                       13
<PAGE>

                    the  time  for  fulfillment  of  such  obligation  shall  be
                    extended  during  the  period  in  which  such  circumstance
                    operates  to  prevent,  delay or  restrict  the  fulfillment
                    thereof,  and the  other  party to this  Lease  shall not be
                    entitled to compensation for any inconvenience,  nuisance or
                    discomfort  thereby  occasioned;  provided that nevertheless
                    the Landlord will use its best efforts to maintain  services
                    essential to the use and  enjoyment  of the Leased  Premises
                    and  provided   further  that  if  the  Landlord   shall  be
                    prevented,  delayed or restricted in the  fulfillment of any
                    such   obligation   hereunder   by  reason  of  any  of  the
                    circumstances set out in sub-paragraph (c) of this paragraph
                    15  and  to  fulfill  such  obligation  could  not,  in  the
                    reasonable  opinion of the  Landlord,  be completed  without
                    substantial additions to or renovations of the Property, the
                    Landlord  may on sixty  (60)  days'  written  notice  to the
                    Tenant terminate this Lease.

WAIVER              17. If either the  Landlord  or the Tenant  shall  overlook,
                    excuse,    condone   or   suffer   any   default,    breach,
                    non-observance, improper compliance or non-compliance by the
                    other of any obligation hereunder, this shall not operate as
                    a waiver of such  obligation in respect of any continuing or
                    subsequent default,  breach, or non-observance,  and no such
                    waiver  shall be  implied  but shall  only be  effective  if
                    expressed in writing.

SALE, DEMOLITION    18.  (a)      The  term  "Landlord"  as used in this  Lease,
AND RENOVATION           means  only  the  owner  for  the  time  being  of  the
                         Property,  so that in the event of any sale or sales or
                         transfer or transfers of the Property, or the making of
                         any  lease or leases  thereof,  or the sale or sales or
                         the  transfer  or  transfers  or  the   assignment   or
                         assignments  of any  such  lease  or  leases,  previous
                         landlords  shall  be and  hereby  are  relieved  of all
                         covenants and  obligations  of Landlord  hereunder.  It
                         shall be deemed and construed without further agreement
                         between the parties,  or their  successors in interest,
                         or between the parties and the  transferee or acquirer,
                         at any such sale, transfer or assignment,  or lessee on
                         the  making  of any such  lease,  that the  transferee,
                         acquirer  or lessee has assumed and agreed to carry out
                         any  and  all  of  the  covenants  and  obligations  of
                         Landlord  hereunder  to  Landlord's  exoneration,   and
                         Tenant shall thereafter be bound to and shall attorn to
                         such  transferee,  acquirer or lessee,  as the case may
                         be, as Landlord under this Lease;

                           (b)    Notwithstanding  anything  contained  in  this
                                  Lease  to  the  contrary,  in  the  event  the
                                  Landlord  intends to  demolish  or to renovate
                                  substantially  all  the  Building,   then  the
                                  Landlord,  upon  giving the Tenant one hundred
                                  and eighty (180) days' written  notice,  shall
                                  have the  right to  terminate  this  Lease and
                                  this  Lease  shall  thereupon  expire  on  the
                                  expiration  of one  hundred  and eighty  (180)
                                  days  from  the  date  of the  giving  of such
                                  notice without compensation of any kind to the
                                  Tenant.

PUBLIC TAKING       19. The Landlord and Tenant shall co-operate,  each with the
                    other,  in  respect  of any  Public  Taking  of  the  Leased
                    Premises or any part  thereof so that the Tenant may receive
                    the  maximum  award  to  which  it is  entitled  in law  for
                    relocation  costs and business  interruption and so that the
                    Landlord  may  receive  the  maximum  award  for  all  other
                    compensation  arising from or relating to such Public Taking
                    (including  all  compensation  for the value of the Tenant's
                    leasehold interest subject to the Public Taking) which shall
                    be the property of the Landlord,  and the Tenant's rights to
                    such  compensation  are hereby assigned to the Landlord.  If
                    the whole or any part of the  Leased  Premises  is  Publicly
                    Taken,  as between  the  parties  hereto,  their  respective
                    rights and obligations under this Lease shall continue until
                    the  day  on  which  the  Public  Taking   authority   takes
                    possession  thereof.  If the whole or any part of the Leased
                    Premises  is Publicly  Taken,  the  Landlord  shall have the
                    option,  to be exercised by written notice to the Tenant, to
