other than Non-Recourse Debt; (b) such Subsidiary does not own any Equity

shall be allowed to provide such representations, warranties, covenants and
indemnities as are customarily required in such transactions so long as no such

payment or recourse against credit losses.

designated as an "Unrestricted Subsidiary" would fail to meet the foregoing
requirements (other than by reason of such Subsidiary no longer being a

          (b) Manner of Production. The certificates representing the Notes
shall be typed, printed, lithographed or engraved or produced by any combination
of these methods or may be produced in any other manner permitted by the rules
of any securities exchange on which the Notes may be listed, all as determined
by the Officers of the Issuer executing such Notes, as evidenced by their
execution of such Notes.

          (c) Sales of Notes. The Notes will be offered and sold initially in a
transaction not subject to the registration requirements of the Securities Act
or any other applicable securities law and, accordingly, may not be sold or
otherwise transferred under any circumstances that would result in a violation
of the registration requirements of the Securities Act or such other law.

          SECTION 2.02. Execution, Authentication and Denominations.

          (a) Execution. Two Officers shall execute the Notes for the Issuer by
facsimile or manual signature in the name and on behalf of the Issuer. The seal
of the Issuer, if any, shall be reproduced on the Notes. If an Officer whose
signature is on a Note no longer holds that office at the time the Trustee or
authenticating agent authenticates the Note, the Note shall be valid
nevertheless.

          (b) Issuance of Notes. The Trustee or any duly appointed
authenticating agent shall authenticate and deliver Notes upon receipt of an
Issuer Order and an Officers' Certificate and, if so requested by the Trustee,
an Opinion of Counsel of the Issuer or the Company that it may reasonably
request in connection with such authentication of Notes. Such Issuer Order shall
specify the amount of Notes to be authenticated and the date on which the
original issue of Notes is to be authenticated. Unless otherwise specified in
such Issuer Order, the Notes shall be issued as Global Notes. On the date
hereof, the aggregate principal amount of Notes outstanding shall equal
$200,000,000, and the aggregate principal amount of Notes outstanding at any
time thereafter shall not exceed said amount, except for Notes authenticated and
delivered upon registration of transfer of, or in exchange for, or in lieu of,
other Notes pursuant to Section 2.05, 2.06, 2.07 or 2.08 hereof.

          (c) Authentication Agents. The Trustee may appoint an authenticating
agent to authenticate Notes. Unless limited by the terms of such appointment, an
authenticating agent may authenticate Notes whenever the Trustee may do so. Each
reference in this Indenture to authentication by the Trustee includes
authentication by such authenticating agent. An authenticating agent has the
same rights as an Agent to deal with the Issuer or an Affiliate of the Issuer.

          (d) Certificates of Authentication. A Note shall not be valid until
the Trustee or any duly appointed authenticating agent manually signs the
certificate of authentication on the Note. The signature shall be conclusive
evidence that the Note has been authenticated under this Indenture.

          (e) Global Notes. Unless otherwise specified in an Issuer Order as
contemplated by Section 2.02(b) hereof, the Notes shall be issued in the form of

Company or any successor thereof.

registered form, without coupons, in minimum denominations of one U.S. Dollar
($1.00).

          SECTION 2.03. Registrar and Paying Agent.

          (a) Registrar. The Issuer shall maintain an office or agency where
Notes may be presented for registration of transfer or for exchange (the
"Registrar") and, through the Trustee as provided in Section 2.03(d) hereof, an
office or agency where Notes may be presented for payment (the "Paying Agent").
The Registrar shall keep a register of the Notes and of their transfer and
exchange (the "Note Register"). The Note Register shall be kept for both the
Global Notes and Definitive Notes and shall record (at minimum) information
relating to the names and addresses of the transferor and transferee of any
Notes transferred or exchanged, the amount so transferred or exchanged, the date
or dates of such transfer or exchange, any payments made with respect to the
Notes and any other information the Registrar reasonably deems appropriate. The
Issuer may have one or more co-registrars and one or more additional Paying
Agents. The term "Paying Agent" includes any additional paying agents.

          (b) Agents. The Issuer shall enter into an appropriate agency
agreement with any Agent not a party to this Indenture which shall incorporate
the terms of the TIA, to the extent required under the TIA. Such agreement shall
implement the provisions of this Indenture that relate to such Agent. The Issuer
shall give prompt written notice to the Trustee of the name and address of any
such Agent and any change in the address of such Agent. If the Issuer fails to
maintain a Registrar and/or Paying Agent, the Trustee shall act as such
Registrar, Paying Agent and/or agent for service of notices and demands. The
Issuer may remove any Agent upon written notice to such Agent and the Trustee;
provided that no such removal shall become effective until (i) the acceptance of
an appointment by a successor Agent to such Agent as evidenced by an appropriate
agency agreement entered into by the Issuer and such successor Agent and
delivered to the Trustee or (ii) notification to the Trustee that the Trustee
shall serve as such Agent until the appointment of a successor Agent in
accordance with clause (i) of this proviso. None of the Company, any Subsidiary
of the Company or any Affiliate of any of them may act as Paying Agent,
Registrar or co-registrar.

          (c) Initial Appointments. The Issuer initially appoints the Trustee as
Registrar and Paying Agent. If, at any time, the Trustee is not the Registrar,
the Registrar shall make available to the Trustee, on or before each Interest
Payment Date and at such other times as the Trustee may reasonably request, the
names and addresses of the Holders as they appear in the Note Register.

          (d) Trustee to Act as Paying Agent. Notwithstanding anything to the
contrary herein, the Trustee shall at all times act as the Paying Agent
hereunder (although the Trustee may appoint one or more additional Paying
Agents).

interest on any Notes, the Issuer shall deposit with the Paying Agent money in
immediately available funds sufficient to pay such principal, premium, if any,
and interest so becoming due, such sum to be held in trust for the benefit of
the Persons entitled to such principal, premium, if any, or interest, if any,
and (unless such Paying Agent is the Trustee) the Issuer will promptly notify
the Trustee of such action or any failure so to act.

          The Issuer will cause each Paying Agent other than the Trustee to
execute and deliver to the Trustee an instrument in which such Paying Agent
shall agree with the Trustee, subject to the provisions of this Section 2.04,
that such Paying Agent will:

          (a) hold all sums held by it for the payment of the principal of,
     premium, if any, or interest on Notes in trust for the benefit of the
     Persons entitled thereto until such sums shall be paid to such Persons or
     otherwise disposed of as herein provided;

          (b) give the Trustee notice of any default by the Issuer (or any other
     obligor upon the Notes) in the making of any payment of principal, premium,
     if any, or interest, if any;

          (c) at any time during the continuance of any such default, upon the
     written request of the Trustee, forthwith pay to the Trustee all sums so
     held in trust by such Paying Agent; and

          (d) acknowledge, accept and agree to comply in all respects with the
     provisions of this Indenture relating to the duties, rights and obligations
     of such Paying Agent.

          The Issuer may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, pay, or
direct any Paying Agent to pay, to the Trustee all sums held in trust by the
Issuer or such Paying Agent, such sums to be held by the Trustee upon the same
trusts as those upon which such sums were held by the Issuer or such Paying
Agent; and, upon such payment by any Paying Agent to the Trustee, such Paying
Agent shall be released from all further liability with respect to such money.

          Any money deposited with the Trustee or any Paying Agent and remaining
unclaimed for two years after such principal, premium, if any, or interest has
become due and payable shall be paid to the Issuer at the request of the Issuer,
and the Holder of such Note shall thereafter, as an unsecured general creditor,
look only to the

Issuer for payment thereof, and all liability of the Trustee or such Paying
Agent with respect to such trust money shall thereupon cease; provided that the
Trustee or such Paying Agent, before being required to make any such repayment,
shall at the expense of the Issuer cause notice to be promptly sent to each
Holder that such money remains unclaimed and that, after a date specified
therein, which shall not be less than 30 days from the date of such
notification, any unclaimed balance of such money then remaining will be repaid
to the Issuer.

          SECTION 2.05. Transfer and Exchange.

          (a) Transfer and Exchange of Global Notes. A Global Note may not be
transferred as a whole except by the Depositary to a nominee of the Depositary,
by a nominee of the Depositary to the Depositary or to another nominee of the
Depositary, or by the Depositary or any such nominee to a successor Depositary
or a nominee of such successor Depositary. All Global Notes will be exchanged by
the Issuer for Definitive Notes (i) in whole if the Issuer delivers to the
Trustee notice from the Depositary that it is unwilling or unable to continue to
act as Depositary or that it is no longer a clearing agency registered under the
Exchange Act and, in either case, a successor Depositary is not appointed by the
Issuer within 120 days after the date of such notice from the Depositary, (ii)

whole but not in part) should be exchanged for Definitive Notes and delivers a
written notice to such effect to the Trustee, (iii) in part with respect to the
portion thereof attributable to the requesting Holder at any time at the request
of such Holder or (iv) in part at the request of the Depositary on behalf of any
holder of a beneficial interest in a Global Note. Upon the occurrence of any of
the events in the preceding clause (i), (ii), (iii) or (iv), Definitive Notes
shall be issued in such names and in such amounts, as the Depositary shall
instruct the Trustee. Global Notes also may be exchanged or replaced, in whole
or in part, as provided in this Section 2.05 and Sections 2.06 and 2.08 hereof.
Every Note authenticated and made available for delivery in exchange for, or in
lieu of, a Global Note or any portion thereof, pursuant to this Section 2.05 or
Section 2.06 or 2.08 hereof, shall be authenticated and, except as provided in
the second sentence of this Section 2.05(a), be made available for delivery in
the form of, and shall be, a Global Note. A Global Note may not be exchanged for
another Note other than as provided in this Section 2.05(a); provided that
beneficial interests in a Global Note may be transferred and exchanged
consistent with the provisions hereof.

          (b) Transfer and Exchange of Beneficial Interests in the Global Notes.
The transfer and exchange of beneficial interests in the Global Notes shall be
effected through the Depositary, in accordance with the provisions of this
Indenture and the Applicable Procedures. If the beneficial interest in the
Global Note to be transferred or exchanged is in a Global Note required to bear
the Restricted Legend, such Person's request shall provide that such Notes are
being transferred or exchanged pursuant to an effective registration statement
under the Securities Act or pursuant to clause (i) or (ii) below, and are

          (i) if such beneficial interest is being transferred to the Person
     designated by DTC as being the beneficial owner, a certification from such
     Person that such Person is the beneficial owner; or

     Act and as to compliance with the restrictions set forth in the legend set
     forth in Section 2.06(d)(ii) hereof.

          (c) Transfer and Exchange of Definitive Notes. Upon request by a
Holder of Definitive Notes and such Holder's compliance with the provisions of
this Section 2.05(c), the Registrar shall register the transfer or exchange of
Definitive Notes. Prior to such registration of transfer or exchange, the
requesting Holder shall present or surrender to the Registrar the Definitive
Notes duly endorsed or accompanied by a written instruction of transfer in form
satisfactory to the Registrar duly executed by such Holder or by its attorney,
duly authorized in writing. If such Definitive Notes are required to bear the
Restricted Legend, such Holder's request shall provide that such Notes are being
transferred or exchanged pursuant to an effective registration statement under
the Securities Act or pursuant to clause (i), (ii) or (iii) below, and are
accompanied by the following additional information and documents, as
applicable:

     Holder for registration in the name of such Holder, without transfer, a

     exemption from registration in reliance upon an exemption from the
     requirements of the Securities Act: (A) a certification to that effect and

     hereof.

          (d) Legends.

          (i) Each Global Note shall bear a legend in substantially the
     following form (the "Global Note Legend"):

          IN PART, TO NOMINEES OF DTC OR TO A SUCCESSOR THEREOF OR SUCH
          SUCCESSOR'S NOMINEE AND, IF IN PART, TO TRANSFERS MADE IN ACCORDANCE
          WITH THE RESTRICTIONS SET FORTH IN THE INDENTURE REFERRED TO ON THE
          REVERSE HEREOF."

          (ii) Each Note shall, except as otherwise provided in this Indenture,
     bear a legend in substantially the following form (the "Restrictive
     Legend"):

          "THIS NOTE HAS NOT BEEN REGISTERED UNDER THE UNITED STATES SECURITIES
          ACT OF 1933, AS AMENDED, OR ANY OTHER APPLICABLE SECURITIES LAW AND,
          ACCORDINGLY, MAY NOT BE SOLD OR OTHERWISE TRANSFERRED UNDER THE
          CIRCUMSTANCES THAT WOULD RESULT IN A VIOLATION OF THE REGISTRATION
          REQUIREMENTS OF SAID ACT OR SUCH OTHER LAW."

          (e) Cancellation and/or Adjustment of Global Notes. At such time as
all beneficial interests in a particular Global Note have been exchanged for
Definitive Notes or a particular Global Note has been redeemed, repurchased or
canceled in whole and not in part, each such Global Note shall be returned to or
retained and canceled by the Trustee in accordance with Section 2.09 hereof. At
any time prior to such cancellation, if any beneficial interest in a Global Note
is exchanged for or transferred to a Person who will take delivery thereof in
the form of Definitive Notes, the principal amount of Notes represented by such
Global Note shall be reduced accordingly and an endorsement shall be made on
such Global Note, by the Trustee or by the Depositary at the direction of the
Trustee, to reflect such reduction. At any time prior to such cancellation,
subject to Section 2.05(c) hereof, if any Definitive Note is exchanged for or
transferred to a Person who will take delivery in the form of a beneficial
interest in a Global Note, the principal amount of Notes represented by such
Global Note shall be increased accordingly and an endorsement shall be made on
such Global Note, by the Trustee or by the Depositary at the direction of the
Trustee, to reflect such increase.

                                      -41-

Transfers or exchanges of Definitive Notes for beneficial interests in Global
Notes may only be affected pursuant to Applicable Procedures.

          (f) General Provisions Relating to Transfers and Exchanges.

          (i) To permit registrations of transfers and exchanges, the Issuer
     shall execute and the Trustee shall authenticate Global Notes and
     Definitive Notes upon receipt of an Issuer Order or at the Registrar's
     request.

          (ii) No service charge shall be made to a holder of a beneficial
     interest in a Global Note or to a Holder of a Definitive Note for any
     registration of transfer or exchange, provided that the Issuer may require
     a payment of a sum sufficient to cover transfer tax, assessments, or
     similar governmental charges payable in connection therewith.

          (iii) The Registrar shall not be required to register the transfer of
     or exchange any Note that is to be redeemed in whole or in part, except the
     unredeemed portion of any Note being redeemed in part.

          (iv) All Global Notes and Definitive Notes issued upon any
     registration of transfer or exchange of Global Notes or Definitive Notes
     shall constitute the valid obligations of the Issuer, evidencing the same
     debt, and entitled to the same benefits under this Indenture, as the Global
     Notes or Definitive Notes surrendered upon such registration of transfer or
     exchange.

          (v) Neither the Issuer nor the Registrar shall be required (A) to
     issue, to register the transfer of or to exchange Notes during a period
     beginning at the opening of business 15 days before the date of any
     redemption of Notes under Article III hereof and ending at the close of
     business on the date of such redemption or (B) to register the transfer of
     or to exchange a Note between a Record Date and the Interest Payment Date
     corresponding thereto.

          (vi) Prior to due presentment for the registration of a transfer of
     any Note, the Issuer, the Trustee and any Agent may deem and treat the
     Person in whose name any Note is registered as the absolute owner of such
     Note for the purpose of receiving payment of principal of, premium, if any,
     and interest on such Notes and for all other purposes, and none of the
     Issuer, the Guarantors, the Trustee or any Agent shall be affected by
     notice to the contrary.

          (g) Restrictive Legend and Removal of Legends. If Notes are issued
upon the transfer, exchange or replacement of Notes subject to restrictions on
transfer and bearing the Restrictive Legend set forth on the form of Note
attached hereto as Exhibit A, or if a request has been made to remove the
Restrictive Legend on a Note, the Note so issued shall bear the Restrictive
Legend, or the Restrictive Legend shall not be removed, as the case may be,
unless there is delivered to the Issuer and the Registrar satisfactory evidence,
which shall include an Opinion of Counsel, as may reasonably be required by

                                    Indenture

<PAGE>

                                      -42-

the Company and the Registrar, that neither the Restrictive Legend nor the
restrictions on transfer set forth therein are required to ensure that transfers
thereof comply with the provisions of the Securities Act, including, if
applicable, that such Note are not "restricted securities" within the meaning of
Rule 144 under the Securities Act and may be transferred pursuant to the
requirements of Rule 144 under the Securities Act. Upon (i) provision of such
satisfactory evidence, or (ii) notification by the Company to the Trustee and
the Registrar of the effectiveness of a registration statement with respect to
the Notes, the Trustee, upon the receipt of an Issuer Order, shall authenticate
and deliver a Note that does not bear the Restrictive Legend.

          SECTION 2.06. Replacement Notes.

          (a) Mutilated Notes, Etc. If a mutilated Note is surrendered to
the Registrar or if the Holder claims that the Note has been lost, destroyed or
wrongfully taken, the Issuer shall issue and the Trustee shall authenticate a
replacement Note of like tenor in the absence of notice to the Issuer or the
Trustee that such Note has been acquired by a bona fide purchaser and if the
Holder satisfies any other reasonable requirements of the Trustee. If required
by the Trustee or the Issuer, an indemnity bond must be supplied by the Holder
sufficient in the judgment of the Trustee and the Issuer to protect the Issuer
and the Trustee and any agent of the Issuer and the Trustee from any loss which
any of them may suffer if a Note is replaced. In case any such mutilated, lost,
destroyed or wrongfully taken Note has become or is about to become due and
payable, the Issuer in its discretion may redeem such Note instead of issuing a
new Note in replacement thereof.

          (b) Replacement Notes. Every replacement Note is an additional
obligation of the Issuer and shall be entitled to the benefits of this Indenture
and of the Security Documents.

          SECTION 2.07. Outstanding Notes.

          (a) Outstanding Generally. Notes outstanding at any time shall include
all Notes that have been authenticated by the Trustee except for those cancelled
by it, those delivered to it for cancellation and those described in this
Section 2.07 as not outstanding. If a Note is replaced pursuant to Section 2.06
hereof, it ceases to be outstanding unless and until the Trustee receives proof
satisfactory to it that the replaced Note is held by a bona fide purchaser. If
the Paying Agent separates and holds in trust, on a maturity date, money
sufficient to pay Notes on such date, then on and after such date, such Notes
cease to be outstanding hereunder and interest thereon shall cease to accrue.

          (b) Notes Held by Issuer or Affiliates. Subject to Section 7.07
hereof, a Note does not cease to be outstanding because the Issuer or one of its
Affiliates holds such Note, provided that in determining whether the Holders of
the requisite principal amount of the outstanding Notes have given any request,
demand, authorization, direction, notice, consent or waiver hereunder, Notes
owned by the Issuer, any Credit Party or any other obligor upon the Notes shall
be disregarded and deemed not to be

                                    Indenture

<PAGE>

                                      -43-

outstanding (in determining whether the Trustee shall be protected in relying
upon any such request, demand, authorization, direction, notice, consent or
waiver, only Notes which a Responsible Officer of the Trustee knows to be so
owned, as conclusively evidenced by the Note Register, shall be so disregarded).
Notes so owned which have been pledged in good faith may be regarded as
outstanding if the pledgee establishes to the satisfaction of the Trustee the
pledgee's right so to act with respect to such Notes and that the pledgee is not
the Issuer or any other obligor upon the Notes.

          On the Issue Date, the Issuer shall furnish the Trustee with an
Officers' Certificate certifying the names of all Subsidiaries of the Company.
The Issuer shall update such information from time to time by further Officers'
Certificates delivered promptly, after each request therefor from the Trustee.
The Trustee may conclusively rely on the most recent such Officers' Certificate
received by it.

          To the extent of any inconsistency between the TIA and the provisions
of this Section 2.07 the provisions of the TIA shall be controlling.

          SECTION 2.08. Temporary Notes.

          Until definitive Notes are ready for delivery, the Issuer may prepare
and the Trustee shall authenticate temporary Notes. Temporary Notes shall be
substantially in the form of definitive Notes but may have insertions,
substitutions, omissions and other variations determined to be appropriate by
the Officers of the Issuer executing the temporary Notes, as evidenced by their
execution of such temporary Notes. If temporary Notes are issued, the Issuer
shall cause definitive Notes to be prepared without unreasonable delay. After
the preparation of definitive Notes, the temporary Notes shall be exchangeable
for definitive Notes upon surrender of the temporary Notes at the office or
agency of the Issuer designated for such purpose pursuant to Section 2.03
hereof, without charge to the Holder. Upon surrender for cancellation of any one
or more temporary Notes, the Issuer shall execute and the Trustee shall
authenticate and deliver in exchange therefor a like principal amount of
definitive Notes of authorized denominations. Until so exchanged, the temporary
Notes shall be entitled to the same benefits under this Indenture as definitive
Notes.

          SECTION 2.09. Cancellation.

          The Issuer at any time may deliver Notes to the Trustee for
cancellation (and shall deliver to the Trustee for cancellation any Notes
purchased by it pursuant to Section 4.10 or 4.15 hereof). The Registrar and the
Paying Agent shall forward to the Trustee any Notes surrendered to them for
transfer, exchange or payment. The Trustee and no other Person shall cancel all
Notes surrendered for registration of transfer, exchange, payment or
cancellation and shall dispose of them in accordance with its normal procedure.
The Issuer may not issue new Notes to replace Notes it has paid in full or
delivered to the Trustee for cancellation.

          SECTION 2.10. CUSIP Numbers.

          The Issuer in issuing the Notes may use "CUSIP" numbers (if then
generally in use), and the Trustee shall use CUSIP numbers in notices of
redemption or exchange as a convenience to Holders. Any such notice may state
that no representation is made as to the correctness of such numbers either as
printed on the Notes or as contained in any notice of redemption or exchange and
that reliance may be placed only on the other identification numbers, if any,
printed on the Notes.

          SECTION 2.11. Defaulted Interest.

          If the Issuer defaults in a payment of interest on the Notes, it shall
pay or cause to be paid, or shall deposit or cause to be deposited with the
Paying Agent money in immediately available funds sufficient to pay, the
defaulted interest plus (to the extent lawful) any interest payable on the
defaulted interest, to the Persons who are Holders on a subsequent Special
Record Date. The Issuer shall fix or cause to be fixed any such Special Record
Date and payment date to the reasonable satisfaction of the Trustee and shall,
at least 15 days before the subsequent Special Record Date, mail to each Holder
and the Trustee a notice that states the Special Record Date, the payment date
and the amount of defaulted interest to be paid. A "Special Record Date", as
used in this Section 2.11 with respect to the payment of any defaulted interest,
shall mean the fifteenth day next preceding the date fixed by the Issuer for the
payment of defaulted interest, whether or not such day is a Business Day.

          SECTION 2.12. Noteholder Lists.

          The Trustee shall preserve in as current a form as is reasonably
practicable the most recent list available to it of the names and addresses of
Holders. If the Trustee is not the Registrar, the Credit Parties shall furnish
to the Trustee, in writing at least five Business Days before each Interest
Payment Date and at such other times as the Trustee may request in writing, a
list in such form and as of such date as the Trustee may reasonably require of
the names and addresses of Holders.

          SECTION 2.13. Communication By Holders with Other Holders.

Pursuant to Section 312(b) of the TIA, Holders may communicate with other
Holders with respect to their rights under this Indenture or the Notes. The
Issuer, the Trustee, the Registrar and the Paying Agent shall be entitled to the
protections of Section 312(c) of the TIA.

                      ARTICLE III REDEMPTION AND PREPAYMENT

          SECTION 3.01. Notices to Trustee.

          If the Issuer elects to redeem Notes pursuant to Section 3.07 hereof,
or is required to redeem Notes pursuant to Section 3.08 hereof, it shall furnish
to the Trustee, at least 30 days but not more than 60 days before the redemption
date, an Officers'

                                    Indenture

<PAGE>

                                      -45-

Certificate setting forth (i) the provision of this Indenture pursuant to which
the redemption shall occur, (ii) the redemption date, (iii) the principal amount
of Notes to be redeemed and (iv) the redemption price.

          SECTION 3.02. Selection of Notes to Be Redeemed.


          If less than all of the Notes are to be redeemed or purchased in an
offer to purchase at any time, the Trustee shall redeem or purchase Notes, or
portions thereof, in such amounts as shall be necessary so that such redemption
or purchase is applied to the principal amount of the Notes on a pro rata basis.
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 3.03. Notice of Redemption.

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

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

          (a) the redemption date;

          (b) the redemption price;

          (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 shall 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 Issuer defaults in making such redemption
     payment, interest on Notes called for redemption ceases to accrue on and
     after the redemption date; and

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

          At the Issuer's request, the Trustee shall give the notice of
redemption in the Issuer's name and at its expense, provided that the Issuer
shall have delivered to the Trustee, at least 45 days prior to the redemption
date, an Officers' Certificate requesting that the Trustee give such notice and
setting forth the information to be stated in such notice as provided in the
preceding paragraph.

          SECTION 3.04. Effect of Notice of Redemption.

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

          SECTION 3.05. Deposit of Redemption Price.

          Prior to 10 a.m. on the applicable redemption date, the Issuer shall,
to the extent sufficient funds are not already on deposit with the Trustee in
the Specified Subsidiary Asset Sale Proceeds Account, deposit with the Trustee
or with the Paying Agent U.S. Dollars sufficient to pay the redemption price of
and accrued interest on all Notes to be redeemed on that date. The Trustee or
the Paying Agent shall promptly return to the Issuer any U.S. Dollars deposited
with the Trustee or the Paying Agent by the Issuer in excess of the amounts
necessary to pay the redemption price of, and accrued interest on, all Notes to
be redeemed.

          If the Issuer complies with the provisions of the preceding paragraph,
on and after the redemption date, interest shall cease to accrue on the Notes or
the portions of Notes called for redemption. 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 shall 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 shall not be so paid upon surrender for redemption
because of the failure of the Issuer to comply with the preceding paragraph,
interest shall 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 4.01 hereof.

          SECTION 3.06. Notes Redeemed in Part.

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

          SECTION 3.07. Optional Redemption.

          The Issuer may at any time, and from time to time, at its option,
redeem the Notes in whole or in part, in a minimum aggregate redemption amount
of $5,000,000, upon not less than 30 nor more than 60 days' notice, at a
redemption price equal to 100% of the principal amount of thereof, plus accrued
and unpaid interest thereon, if any, to the applicable redemption date (subject
to the right of Holders of record on the relevant interest Record Date to
receive interest due on the relevant Interest Payment Date). Any redemption
pursuant to this Section 3.07 shall be made pursuant to the provisions of
Sections 3.01 through 3.06 hereof.

          SECTION 3.08. Mandatory Redemption.

          (a) Specified Subsidiary Asset Sales. Except as provided in
Section 3.08(b) hereof, in the event of one or more Specified Subsidiary Asset
Sales, the Company shall, upon receipt by the Company or the applicable
Subsidiary of the Net Cash Proceeds of such Specified Subsidiary Asset Sale,
deposit, or cause to be deposited, and thereafter retain, the entire amount of
such Net Cash Proceeds into the Specified Subsidiary Asset Sale Proceeds
Account. Once the aggregate amount of such Net Cash Proceeds shall exceed
$5,000,000 or more then, upon not less than 30 nor more than 60 days' notice
(but in no event more than 70 days after such Specified Subsidiary Asset Sale),
the Issuer shall instruct the Trustee to use the Net Cash Proceeds then held in
the Specified Subsidiary Asset Sale Proceeds Account to redeem the maximum
principal amount of the Notes that may be redeemed out of such Net Cash Proceeds
at a redemption price of 100% of the principal amount thereof, plus accrued and
unpaid interest thereon, if any, to the applicable redemption date (subject to
the right of Holders of record on the relevant Record Date to receive interest
due on the relevant Interest Payment Date). Amounts so deposited into the
Specified Subsidiary Asset Sale Proceeds Account may not be withdrawn except to
effect such redemption as provided herein unless all Notes have been redeemed or
otherwise paid in full in cash or discharged in accordance with the provisions
of this Indenture.

          (b) Non-Cash Consideration. To the extent that the Company or any of
its Restricted Subsidiaries receive consideration as a result of or in
connection with a Specified Subsidiary Asset Sale that are not Net Cash Proceeds
thereof, such consideration shall become part of the Collateral and, with
respect to such consideration, the Issuer shall not be required to comply with
Section 3.08(a) hereof.

          (c) General Redemption Provisions Applicable. Any redemption pursuant
to this Section 3.08 shall be made pursuant to the provisions of Sections 3.01
through 3.06 hereof.

          SECTION 3.09. Offer to Purchase by Application of Excess Proceeds.

          In the event that, pursuant to Section 4.10(a) hereof, the Issuer
shall be required to commence an Asset Sale Offer, it shall follow the
procedures specified below.

          The Asset Sale Offer shall remain open for a period of 20 Business
Days following its commencement and no longer, except to the extent that a
longer period is required by applicable law (the "Offer Period"). No later than
five Business Days after the termination of the Offer Period (the "Purchase
Date"), the Issuer shall purchase the principal amount of Notes required to be
purchased pursuant to Section 4.10 hereof (the "Offer Amount") or, if less than
the Offer Amount has been tendered, all Notes tendered in response to the Asset
Sale Offer. Payment for any Notes so purchased shall be made in the same manner
as interest payments are made.

<PAGE>

                                      -48-

          If the Purchase Date is on or after a Record Date and on or before the
related Interest Payment Date, any accrued and unpaid interest shall be paid to
the Person in whose name a Note is registered at the close of business on such
Record Date, and no additional interest shall be payable to Holders who tender
Notes pursuant to the Asset Sale Offer.

          Upon the commencement of an Asset Sale Offer, the Issuer shall send,
by first class mail, a notice to the Trustee and each of the Holders, with a
copy to the Trustee. The notice shall contain all instructions and materials
necessary to enable such Holders to tender Notes pursuant to the Asset Sale
Offer. The Asset Sale Offer shall be made to all Holders. The notice, which
shall govern the terms of the Asset Sale Offer, shall state:

          (a) that the Asset Sale Offer is being made pursuant to this Section
     3.09 and Section 4.10(a) hereof and the length of time the Asset Sale Offer
     shall remain open;

          (b) the Offer Amount, the purchase price and the Purchase Date;

          (c) that any Note not tendered or accepted for payment shall continue
     to accrue interest;

          (d) that, unless the Issuer defaults in making such payment, any Note
     accepted for payment pursuant to the Asset Sale Offer shall cease to accrue
     interest after the Purchase Date;

          (e) that Holders electing to have a Note purchased pursuant to any
     Asset Sale Offer shall be required to surrender the Note, with the form
     entitled "Option of Holder to Elect Purchase" on the reverse of the Note
     completed, or transfer by book-entry transfer, to the Issuer, a Depositary,
     if appointed by the Issuer, or a Paying Agent at the address specified in
     the notice at least three days before the Purchase Date;

          (f) that Holders shall be entitled to withdraw their election if the
     Issuer, the Depositary or the Paying Agent, as the case may be, receives,
     not later than the expiration of the Offer Period, a telegram, telex,
     facsimile transmission or letter setting forth the name of the Holder, the
     principal amount of the Note the Holder delivered for purchase, and a
     statement that such Holder is withdrawing his election to have such Note
     purchased;

          (g) that, if the aggregate principal amount of Notes surrendered by
     Holders exceeds the Offer Amount, the Issuer shall select the principal of
     the Notes to be purchased on a pro rata basis; and

                                    Indenture

          (h) that Holders whose Notes were purchased only in part shall be
     issued new Notes equal in principal amount to the unpurchased portion of
     the Notes surrendered (or transferred by book-entry transfer).

          On or before 10:00 a.m. on the Purchase Date, the Issuer shall, to the
extent lawful, accept for payment, on a pro rata basis to the extent necessary,
the Offer Amount or portions thereof tendered pursuant to the Asset Sale Offer,
or if less than the Offer Amount has been tendered, all Notes tendered, and
shall deliver to the Trustee an Officers' Certificate stating that such Notes or
portions thereof were accepted for payment by the Issuer in accordance with the
terms of this Section 3.09. The Issuer, the Depositary or the Paying Agent, as
the case may be, shall promptly (but in any case not later than five days after
the Purchase Date) mail or deliver to each tendering Holder an amount equal to
the purchase price of the Notes tendered by such Holder and accepted by the
Issuer for purchase, and the Issuer shall promptly issue a new Note, and the
Trustee, upon written request from the Issuer shall authenticate and mail or
deliver such new Note to such Holder, in a principal amount equal to any
unpurchased portion of the Note surrendered. Any Note not so accepted shall be
promptly mailed or delivered by the Issuer to the Holder thereof. The Issuer
shall publicly announce the results of the Asset Sale Offer on the Purchase
Date.

          Other than as specifically provided in this Section 3.09, any purchase
pursuant to this Section 3.09 shall be made pursuant to the provisions of
Sections 3.01 through 3.06 hereof.

                              ARTICLE IV COVENANTS

          SECTION 4.01. Payment of Notes.

          The Issuer shall pay or cause to be paid the principal of, premium, if
any, and interest, if any, on the Notes on the dates and in the manner provided
in the Notes. Principal, premium, if any, and interest, if any, shall be
considered paid on the date due if the Paying Agent, if other than the Company
or a Subsidiary or Affiliate thereof, holds as of 10:00 a.m. Eastern Time on the
due date money deposited by the Issuer in immediately available funds and
designated for and sufficient to pay all principal, premium, if any, and
interest, if any, then due.

          The Issuer shall pay interest (including post-petition interest in any

          The Issuer shall maintain in the Borough of Manhattan, the City of New

of the Trustee, Registrar or co-registrar) where Notes may be surrendered for
registration of transfer or for exchange and where notices and demands (which,
with respect to demands, must be an office or agency of the Issuer and may not

all such purposes and may from time to time rescind such designations, provided
that no such designation or rescission shall in any manner relieve the Issuer of
its obligation to maintain an office or agency in the Borough of Manhattan, the
City of New York for such purposes. The Issuer shall give prompt written notice
to the Trustee of any such designation or rescission and of any change in the
location of any such other office or agency.

the best of his or her knowledge the Credit Parties have kept, observed,
performed and fulfilled each and every covenant contained in this Indenture and

certification of such financial statements, nothing has come to their attention
that would lead them to believe that the Company has violated any provisions of
Section 3.08, 3.09, Article IV, V or VI hereof or, if any such

                                    Indenture

<PAGE>

                                      -52-

it being understood that such accountants shall not be liable directly or
indirectly to any Person for any failure to obtain knowledge of any such
violation.

          (c) Notice of Defaults. In the event that any Credit Party becomes
aware of any events which would constitute a Default or Event of Default, the
Company within five Business Days after it becomes aware thereof, shall give to
the Trustee written notice of such events, their status and the nature of any
actions taken or proposed to be taken by the Company in respect of such events.

          (d) Certain Inspection and Information Rights. So long as any Holder
that is a Bank and that is party to the Credit Agreement on the Issue Date shall
continue to hold any of the Notes distributed to it on the Issue Date (any such
Holder being herein called a "Designated Holder"), the Company will, in order to
permit such Designated Holder to continue to hold the Notes issued to it in
accordance with safe and sound banking practices, following a written request
therefor delivered to the Company 30 days prior to the date requested for
review, furnish to such Designated Holder, in addition to the financial
information, reports, certificates and other information required to be
delivered from time to time pursuant to Sections 4.03 hereof, such other
information regarding the operations, business affairs and financial condition
of the Company and its Subsidiaries as such Designated Holder may reasonably
request. No Holders other than Designated Holders (including any transferee of
the Notes from any Designated Holder) shall be entitled to the benefits of this
Section 4.04(d).

          Each of the Issuer and the Guarantors agrees (to the extent that it
may lawfully do so) that it shall not at any time insist upon, or plead, or in

premium, if any, or interest on the Notes as contemplated herein or any payments
required under any Security Documents, wherever enacted, now or at any time
hereafter in force, or that may affect the covenants or the performance of this
Indenture; and (to the extent that it may lawfully do so) each of the Issuer and
the Guarantors hereby expressly waives all benefit or advantage of any such law
and covenants that it shall not hinder, delay or impede the execution of any
power herein granted to the Trustee, but shall suffer and permit the execution
of every such power as though no such law had been enacted.

have been permitted to be made at such time under this Section 4.07, the Company
shall be deemed to be in breach of this Section 4.07).

          SECTION 4.08. Certain Dividend and Other Payment Restrictions.

          The Company will not, and will not permit any of its Restricted
Subsidiaries to, directly or indirectly, create or otherwise cause or suffer to

     Indebtedness being refinanced;

          (h) Liens securing Purchase Money Indebtedness referred to in clause
     (k) of the definition of Permitted Liens that limit the right of the

on the Issue Date (and, to the extent that such Indebtedness would not have been
permitted to be Incurred at such time under this Section 4.09, the Company shall

          SECTION 4.10. Asset Sales and Specified Subsidiary Asset Sales and
Casualty Events.

          (a) Asset Sales. The Company shall not, and shall not permit any of
its Restricted Subsidiaries to, consummate 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 (if other than a Casualty Event) at least equal to
the Fair Market Value (taking into account the value of all consideration
received in connection therewith and set forth in an Officers' Certificate
delivered to the Trustee) of the Property or Equity Interests that are the
subject of such Asset Sale, (ii) at least 80% of the consideration therefor (if
other than a Casualty Event) is in the form of Qualified Cash Equivalents, (iii)
the Net Cash Proceeds received by the Company (or such Restricted Subsidiary, as
the case may be) from such Asset Sale shall be remitted, subject to any
Intercreditor Agreement, to the Trustee for deposit into the Asset Sale Proceeds
Account free of any Lien (other than the Liens of the Security Documents and any
Working Capital Facility), and (iv) the Company (or such Restricted Subsidiary,
as the case may be) shall take such action as shall be necessary under 6.03
hereof in order to maintain the Lien of the Trustee on any other consideration
received in such Asset Sale. The Net Cash Proceeds from such Asset Sale shall be
retained in the Asset Sale Proceeds Account and shall be available pursuant to
Sections 9.03 and 9.04 hereof (x) in the case of Net Cash Proceeds of a Casualty
Event, to be applied to the repair, rebuilding or replacement of the Property
subject to such Casualty Event and (y) in the case of any other Net Cash
Proceeds of such Asset Sale, to the reinvestment into Property that is used or
useful in a Permitted Business, provided that to the extent all of the Net Cash
Proceeds have not been so applied to such repair, rebuilding, replacement or
reinvestment within 365 days following the receipt of such Net Cash Proceeds (or
within such shorter period as shall be specified by the Company), such remaining
Net Cash Proceeds shall be applied to the making of an Asset Sale Offer as
provided in the next-following paragraph. The aggregate amount of the Net Cash
Proceeds remaining at the end of such period after the application of such Net
Cash

                                    Indenture

<PAGE>

                                      -62-

Proceeds to the repair, rebuilding, replacement or reinvestment referred to
therein, shall constitute "Excess Proceeds."

          When the aggregate amount of Excess Proceeds equals or exceeds
$10,000,000, the Issuer will be required to make an offer to all Holders (an
"Asset Sale Offer") to purchase the maximum principal amount of Notes that may
be purchased out of the Excess Proceeds, at a purchase price in cash in an
amount equal to 100% of the principal amount thereof, plus accrued and unpaid
interest thereon, if any, to the date of purchase, in accordance with the
procedures set forth in Article III hereof. To the extent that any Excess
Proceeds remain after consummation of an Asset Sale Offer, the Issuer may use
such Excess Proceeds for any purpose not otherwise prohibited by this Indenture.
If the aggregate principal amount of Notes tendered in such Asset Sale Offer
exceeds the amount of Excess Proceeds, the Trustee shall select the Notes to be
purchased on a pro rata basis. Upon completion of such Asset Sale Offer, the
amount of Excess Proceeds shall be reset at zero for purposes of the first
sentence of this paragraph.

          (b) Specified Subsidiary Asset Sales and Casualty Events. The Company
shall not, and shall not permit any of its Restricted Subsidiaries to,
consummate any Specified Subsidiary Asset Sale unless (i) the Company (or such
Restricted Subsidiary, as the case may be) shall ensure that the consideration
received at the time of such Specified Subsidiary Asset Sale is at least equal
to the Fair Market Value (including as to the value of all consideration other
than Qualified Cash Equivalents and set forth in an Officers' Certificate
delivered to the Trustee) of the Property or Equity Interests issued or sold or
otherwise disposed of, (ii) at least 80% of the consideration therefor shall be
in the form of Qualified Cash Equivalents (provided that the foregoing
requirement that 80% of the consideration be in the form of Qualified Cash
Equivalents shall not apply to a Qualified GCUK Asset Sale), (iii) in the case
of any sale of Global Marine, GCUK or any of their Subsidiaries, any
Indebtedness of the Company or any of its Subsidiaries to the entity being sold
shall have been repaid or satisfied, (iv) the Net Cash Proceeds received by the
Company (or such Restricted Subsidiary, as the case may be) from such Specified
Subsidiary Asset Sale shall be remitted to the Trustee for deposit into the
Specified Subsidiary Asset Sale Proceeds Account free of any Lien (other than
the Lien of the Security Documents, the Camelot Deed, the FTN Agreement, the
GCUK Finance Lease, the Deed of Grant of Use and the Freenet Agreement), and the
Company (or such Restricted Subsidiary, as the case may be) shall take such
action as shall be necessary under 6.03 hereof in order to maintain the Lien of
the Trustee on any other consideration received in such Specified Subsidiary
Asset Sale and (v) such Net Cash Proceeds shall be applied in accordance with
Section 3.08 hereof; provided that, notwithstanding anything in this Section
4.10(b), any Property subject to (A) the RNSA and the Camelot Deed, (B) the FTN
Agreement, (C) the GCUK Finance Lease and the Deed of Grant of Use and (D) the
Freenet Agreement may be transferred in accordance therewith, any proceeds from
the sale or other disposition of such Property shall be remitted promptly to
Camelot, ESC, Network Rail or Ericcson, respectively, to the extent of the
obligations owed to such respective parties under those respective agreements,
and may be retained by those respective parties to such extent, and the Trustee
shall hold in trust and promptly deliver to any such respective party any
Property which the Trustee

                                    Indenture

                                      -63-

receives and for which the Trustee has been informed in writing by the Company
as set forth in an Officers' Certificate of the Company that such Property is
subject to Liens under such respective aforementioned agreement, until such time
as the obligations under such agreements, respectively, have been paid and
performed in full.

          Upon any Specified Subsidiary Casualty Event, (i) the Net Cash
Proceeds received by the Company (or any of its Restricted Subsidiaries) from
such Specified Subsidiary Casualty Event shall be remitted to the Trustee for
deposit into the Specified Subsidiary Casualty Event Proceeds Account free of
any Lien (other than the Lien of the Security Documents, the Camelot Deed, the
FTN Agreement, the GCUK Finance Lease, the Deed of Grant of Use and the Freenet
Agreement) and (ii) such Net Cash Proceeds shall be retained in the Specified
Subsidiary Casualty Event Proceeds Account and applied to the repair, rebuilding
or replacement of the Property subject to such Specified Subsidiary Casualty
Event, provided that if such Net Cash Proceeds shall not have been so applied
within 360 days following the receipt of such Net Cash Proceeds (or within such
shorter period as shall be specified by the Company), the balance of such Net
Cash Proceeds shall be transferred to the Specified Subsidiary Asset Sale
Proceeds Account and shall be applied in accordance with the provisions of the
preceding paragraph as if such Net Cash Proceeds constituted proceeds of a
Specified Subsidiary Asset Sale; provided further that, notwithstanding anything
in this Section 4.10(b), any proceeds from any Specified Subsidiary Casualty
Event in respect of Property subject to (A) the Camelot Deed or the RNSA, to the
extent of the obligations owed to Camelot under the Camelot Deed or the RNSA, as
the case may be, shall promptly be remitted to Camelot and may be retained by
Camelot, (B) the FTN Agreement, to the extent of the obligations owed to ECS,
shall be remitted promptly to ECS and may be retained by ECS, (C) the GCUK
Finance Lease and the Deed of Grant of Use, to the extent of the obligations
owed to Network Rail, shall be remitted promptly to Network Rail and may be
retained by Network Rail and (D) the Freenet Agreement, to the extent of the
obligations owed to Freenet , shall be remitted promptly to Freenet and may be
retained by Freenet, and the Trustee shall hold in trust and promptly deliver to
any such respective party any Property which the Trustee receives and for which
the Trustee has been informed in writing by the Company as set forth in an
Officers' Certificate of the Company that such Property is subject to Liens
under such respective aforementioned agreement, until such time as the
obligations under such agreements, respectively, have been paid and performed in
full.

          For the avoidance of doubt, nothing in this Indenture shall be deemed
to imply any right of Global Crossing (UK) Telecommunications Limited to act in
contravention of the Camelot Deed or the RNSA.

          (c) Determination of Cash Proceeds. The amount of (i) any liabilities
of the Company or any Restricted Subsidiary of the Company (other than
contingent liabilities and liabilities that are by their terms subordinated to
the Notes or Note Guarantees), in each case as shown on the Company's (or such
Restricted Subsidiary's, as the case may be) most recent balance sheet, that are
assumed by the transferee of any such Property pursuant to an agreement that
releases the Company and any Restricted Subsidiary, as applicable, from all
liability in respect thereof, (ii) Indebtedness of any

                                    Indenture

                                      -64-

Restricted Subsidiary of the Company that is no longer a Restricted Subsidiary
of the Company as a result of an Asset Sale or Specified Subsidiary Asset Sale,
to the extent that the Company and each other Restricted Subsidiary of the
Company are released from any Guarantee of payment of the principal amount of
such Indebtedness in connection with such Asset Sale or Specified Subsidiary
Asset Sale and such Indebtedness is Non-Recourse Debt and (iii) any securities,
notes or other obligations received by the Company (or such Restricted
Subsidiary, as the case may be) from such transferee that are contemporaneously
(subject to ordinary settlement periods) converted by the Company (or such
Restricted Subsidiary, as the case may be) into Qualified Cash Equivalents (to
the extent of the Qualified Cash Equivalents received), will be deemed to be
Qualified Cash Equivalents for purposes of determining the percentage of the
consideration received in connection with any Asset Sale or Specified Subsidiary
Asset Sale that consists of Qualified Cash Equivalents.

          (d) Compliance with Applicable Law. To the extent that the provisions
of any securities laws or regulations conflict with the Asset Sale, Specified
Subsidiary Asset Sale or Specified Subsidiary Casualty Event provisions of this
Indenture, the Issuer shall comply with the applicable securities laws and
regulations and shall not be deemed to have breached its obligations under the
Asset Sale, Specified Subsidiary Asset Sale or Specified Subsidiary Casualty
Event provisions of this Indenture, as the case may be, by virtue thereof.

          SECTION 4.11. Transactions with Affiliates.

          The Company will not, and will not permit any of its Restricted
Subsidiaries to, make any payment to, or sell, lease, transfer or otherwise
dispose of any of its Property to, or purchase any Property from, or enter into
or make or amend any transaction, contract, agreement, understanding, loan,
advance or Guarantee with, or for the benefit of, any Affiliate of the Company
or of its Restricted Subsidiaries (each of the foregoing, an "Affiliate
Transaction"), unless (a) such Affiliate Transaction is on terms that are not
materially less favorable to the Company or the relevant Restricted Subsidiary
thereof than those that would have been obtained in a comparable transaction by
the Company or such Restricted Subsidiary with an unrelated Person and (b) the
Company delivers to the Trustee (i) with respect to any Affiliate Transaction or
series of related Affiliate Transactions involving aggregate consideration in
excess of $2,000,000, a resolution of the Board of Directors of the Company set

complies with the preceding clause (a) and that such Affiliate Transaction has
been approved by a majority of the disinterested members of such Board of
Directors and (ii) with respect to any Affiliate Transaction or series of
related Affiliate Transactions involving consideration in excess of $10,000,000,

     thereof and any Unrestricted Subsidiary or other Affiliate (provided that
     in the case of this clause (h), such agreements are on terms that are no
     less favorable to the Company or the relevant Restricted Subsidiary than
     those that could have been obtained at the time of such transaction in an
     arm's-length transaction with an unrelated third party or, in the case of a
     transaction with an Unrestricted Subsidiary, are either (i) entered into in
     connection with a transaction involving the selection by a customer of

     providing such services;

          (i) any transaction entered into in the ordinary course of business
     between the Company or any Restricted Subsidiary thereof and any
     Unrestricted Subsidiary (provided that in the case of this clause (i), such
     agreements are on terms that are no less favorable to the Company or the

Subsidiaries and the Company or any of its other Subsidiaries or (ii) Global
Marine or any of its Subsidiaries and the Company or any of its other
Subsidiaries, shall in each case be on terms that are not materially less
favorable to GCUK or such Subsidiary, or Global Marine or such Subsidiary, as

          The Company will not, and will not permit any of its Restricted

          SECTION 4.14. Corporate Existence.

          Subject to Article V hereof, the Company shall do or cause to be done
all things necessary to preserve and keep in full force and effect (a) its
corporate existence, and the corporate, partnership or other existence of each
of its Subsidiaries, in accordance with the respective organizational documents
(as the same may be amended from time to time) of the Company or any such
Subsidiary and (b) the rights (charter and statutory), licenses and franchises
of the Company and its Subsidiaries, provided that the Company shall not be
required to preserve any such right, license or franchise, or the corporate,
partnership or other existence of any of its Subsidiaries, if the Board of
Directors of the Company shall determine 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 is not adverse in any
material respect to the Holders. The Issuer shall do or cause to be done all
things necessary to preserve and keep in full force and effect its corporate
existence in accordance with its organizational documents (as the same may be
amended from time to time).

          SECTION 4.15. Offer to Repurchase Upon Change of Control.

          (a) Change of Control Offer. Upon the occurrence of a Change of
Control, each Holder of Notes will have the right to require the Issuer to
purchase all or any part of such Holder's Notes pursuant to the offer described
below (the "Change of Control Offer") at a purchase price in cash (the "Change
of Control Payment") equal to 101% of the aggregate principal amount thereof,
plus accrued and unpaid interest, if any, thereon to the date of purchase
(subject to the right of Holders of record on the relevant Record Date to
receive interest due on the relevant Interest Payment Date), provided that the
Issuer shall not be obligated to repurchase Notes pursuant to this covenant in
the event that it has exercised its rights to redeem all of the Notes as
described in Section 3.07 hereof. Within 30 days following any Change of
Control, the Issuer will mail a notice to each Holder describing the transaction
or transactions that constitute the Change of Control and offering to purchase
Notes on the date specified in such notice, which date shall be no earlier than
30 and no later than 60 days from the date such notice is mailed (the "Change of
Control Payment Date"), in accordance with the procedures required by this
Indenture and described in such notice. The Issuer will comply with the
requirements of Rule 14e-l under the Exchange Act and any other securities laws
and regulations to the extent such laws and regulations are applicable in
connection with the purchase of Notes as a result of a Change of Control. To the
extent that the provisions of any securities laws or regulations conflict with
any of the provisions of this Section 4.15, the Issuer will comply with the
applicable securities laws and regulations and will be deemed not to have
breached its obligations under this covenant by virtue thereof.

          (b) Change of Control Payment Date. On the Change of Control Payment
Date, the Issuer will, to the extent lawful, (l) accept for payment all Notes or
portions thereof properly tendered pursuant to the Change of Control Offer, (2)
deposit with the Paying Agent an amount equal to the Change of Control Payment
in respect of all Notes or portions thereof so tendered and (3) deliver or cause
to be delivered to the

                                    Indenture

<PAGE>

                                      -68-

Trustee Notes so accepted together with an Officers' Certificate stating the
aggregate principal amount of Notes or portions thereof being purchased by the
Issuer. The Paying Agent will promptly mail or deliver to each Holder of Notes
so tendered the Change of Control Payment for such Notes, and the Trustee will
promptly authenticate and mail or deliver (or cause to be transferred by book
entry) to each Holder a new Note equal in principal amount to any unpurchased
portion of Notes surrendered, if any. The Issuer will publicly announce the
results of the Change of Control Offer on or as soon as practicable after the
Change of Control Payment Date.

          (c) Offers by Third Parties. Notwithstanding anything to the contrary
in this Section 4.15, the Issuer shall not be required to make a Change of
Control Offer upon the occurrence of 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 Section 4.15, and purchases
all Notes validly tendered and not withdrawn under such Change of Control Offer.

          (d) Other Change of Control Offers. Nothing herein shall be deemed to
prohibit the Company or any of its Subsidiaries from entering into similar
change of control repurchase, redemption or prepayment provisions with respect
to any other Indebtedness permitted hereunder (it being understood that no
subordinated Indebtedness may be repurchased, redeemed or prepaid prior to the
Change of Control Payment Date referred to in paragraph (a) of this Section
4.15, except as otherwise permitted by this Indenture).

          SECTION 4.16. Business Activities; Holding Company Status.

          The Company will not, and will not permit any of its Restricted
Subsidiaries to, engage in any business other than a Permitted Business.

          The Company will not engage in any business or other activity other
than the business of holding Equity Interests in its Subsidiaries and activities
reasonably related thereto, including (a) the Incurrence of Indebtedness
permitted to be Incurred hereunder and (b) the payment of (i) directors' fees,
salaries and fees, costs and expenses in respect of professional and related
services which may be rendered on behalf of the Company and its Subsidiaries
from time to time, including the fees and expenses of accountants, lawyers,
investment bankers and other consultants retained in connection with matters
affecting the Company and its Subsidiaries collectively, (ii) premiums, fees and
expenses in connection with insurance policies and employee benefit programs
(including workmen's compensation) and other Employee Entitlements maintained on
behalf of the Company or any of its Subsidiaries and (iii) fees, costs and
expenses incurred in connection with sales, dispositions, transfers,
acquisitions and financings/refinancings including banking and underwriting fees
(including underwriters discounts).

          SECTION 4.17. Issuances and Sales of Certain Equity Interests.

          The Company (a) will not, and will not permit any of its Restricted
Subsidiaries to, transfer, convey, sell, lease or otherwise dispose of any
Equity Interests in any Wholly-Owned Restricted Subsidiary of the Company to any
Person (other than the Company or a Wholly Owned Restricted Subsidiary of the
Company), unless (i) such transfer, conveyance, sale, lease or other disposition
is of all the Equity Interests in such Wholly Owned Restricted Subsidiary and
(ii) the Net Cash Proceeds from such transfer, conveyance, sale, lease or other
disposition are applied in accordance with Sections 3.08 or 3.09 hereof, as the
case may be, and 4.10 hereof, as applicable, and (b) will not permit any Wholly
Owned Restricted Subsidiary of the Company to issue any of its Equity Interests
(other than, if necessary, shares of its Capital Stock constituting directors'
qualifying shares) to any Person other than to the Company or a Wholly Owned
Restricted Subsidiary of the Company. Notwithstanding the foregoing, the Company
will not, and will not permit any of its Subsidiaries to, sell, transfer or
otherwise dispose of any Equity Interest in the Issuer if, after giving effect
thereto, the Issuer shall cease to be a Wholly Owned Restricted Subsidiary of
the Company.

          SECTION 4.18. Designation and Revocation of Designation of
Unrestricted Subsidiaries.

          The Company may designate a Restricted Subsidiary that is a
Receivables Entity to be an Unrestricted Subsidiary if (1) such designation is
in compliance with the provisions of the definition of "Unrestricted
Subsidiary," and (2) such designation is evidenced to the Trustee by delivering
to the Trustee of a copy of a Board Resolution of the Company giving effect to
such designation and an Officers' Certificate certifying that (a) such
designation complies with the requirements of the definition of Unrestricted
Subsidiary and (b) the Company was permitted to make a Permitted Investment or
Restricted Investment at the time of such designation in an amount equal to the
Company's interest in the Fair Market Value of such Subsidiary on such date.

          The Company may revoke the designation of a Subsidiary as an
Unrestricted Subsidiary by delivering to the Trustee a Board Resolution of the
Company, provided that the Company shall not revoke such designation unless (x)
no Default or Event of Default shall have occurred and be continuing at the time
of or after giving effect to such revocation and (y) all Liens and Indebtedness
of such Unrestricted Subsidiary outstanding immediately following such
revocation would, if Incurred by a Restricted Subsidiary at such time, have been
permitted to be Incurred at such time for all purposes under this Indenture. To
be effective, any such revocation delivered to the Trustee shall be accompanied
by an Officers' Certificate of the Company to the effect that the requirements
of this Section 4.18 shall have been satisfied with respect to such revocation.

          SECTION 4.19. Guarantee Supplements.

          If at any time after the date hereof the Company shall form or acquire
any new Subsidiary that shall constitute a Material Subsidiary (other than a
Receivables Entity), or if after the Issue Date any Subsidiary not a Material
Subsidiary (whether or not in existence on the Issue Date) shall become a
Material Subsidiary (other than a Receivables Entity), the Company will within
10 days thereof cause such new or existing Subsidiary to execute and deliver to
the Trustee a Guarantee Supplement in substantially the form of Exhibit B
hereto, and thereby to become a "Guarantor" and a "Credit Party" hereunder and
under the Global Security Agreement, and will (i) deliver such Opinions of
Counsel in New York and applicable foreign jurisdictions as to (x) the valid
existence of such Guarantor, (y) the due authorization, execution and
enforceability of such Guarantee Supplement and (z) such other matters as the
Trustee may reasonably request and (ii) take such action (including executing
and delivering such Security Documents, instruments of further assurance and
amendments or supplements thereto, and delivering such additional Opinions of
Counsel and other documents or instruments as required under Section 6.03(c)
hereof), in order that such new or existing Subsidiary shall grant Liens on all
Property of such Subsidiary then existing or thereafter arising that are
included in the definition of "Collateral" in Section 1.01 hereof (but subject
to Section 6.02 hereof).

          Notwithstanding the foregoing, the Company shall not be required to
cause a Subsidiary of the Company to comply with the first paragraph of this
Section 4.19 in connection with a Qualified GCUK Asset Sale, or any Restricted
Investment by the Company in any Restricted Subsidiary (including the surviving
or continuing entity following a Qualified GCUK Asset Sale), so long as after
giving effect thereto, such surviving or continuing entity, or such Restricted
Subsidiary, is a Qualified Restricted Subsidiary; provided that if the surviving
or continuing entity in such Qualified GCUK Asset Sale or any Subsidiary
thereof, or if any Qualified Restricted Subsidiary or any Subsidiary thereof,
Guarantees any Indebtedness or other obligations of any Credit Party, or grants
a Lien upon the Property of such entity or Qualified Restricted Subsidiary or
any Subsidiary of either thereof securing any Indebtedness or other obligations
of any Credit Party (including any Indebtedness under any Working Capital
Facility) then the Company shall be required to comply with the first paragraph
of this Section 4.19 with respect to such entity, Qualified Restricted
Subsidiary or Subsidiary, as the case may be, and the Property thereof.

          SECTION 4.20. Further Instruments and Acts.

          Each Credit Party agrees that at any time and from time to time, upon
the written request of the Trustee, it shall promptly and duly execute and
deliver or cause to be duly executed and delivered any and all such further
instruments and documents as the Trustee may reasonably deem desirable in
obtaining the full benefits of this Indenture and of the rights and powers
herein granted.

          SECTION 4.21. Payments for Consent.

          Neither the Company nor any of its Subsidiaries shall, directly or
indirectly, pay or cause to be paid any consideration, whether by way of
interest, fee or otherwise, to any Holder for or as an inducement to any
consent, waiver or amendment of any of the terms or provisions of this
Indenture, the Notes or any of the Security Documents unless such consideration
is offered to be paid or is paid to all Holders that consent, waive or agree to
amend such terms or provisions of this Indenture, the Notes or the Security
Documents in the time frame set forth in the solicitation documents relating to
such consent, waiver or agreement.

              ARTICLE V CONSOLIDATION, MERGER AND SALE OF PROPERTY

          SECTION 5.01. Merger, Consolidation, or Sale of Property.

          The Company will not, directly or indirectly, consolidate or merge
with or into (whether or not the Company is the surviving corporation), or sell,
assign, transfer, convey or otherwise dispose of all or substantially all of the
Property of the Company and its Restricted Subsidiaries, taken as a whole, in
one or more related transactions, to another Person unless: (a) the Company is
the surviving corporation or the Person formed by or surviving any such
consolidation or merger (if other than the Company) or to which such sale,
assignment, transfer, conveyance or other disposition shall have been made is a
corporation organized or existing under the laws of the United States, any state
thereof or the District of Columbia, France, Germany, the United Kingdom,
Switzerland, Luxembourg, Belgium, the Netherlands or Bermuda; (b) the Person
formed by or surviving any such consolidation or merger (if other than the
Company) or the Person to which such sale, assignment, transfer, conveyance or
other disposition shall have been made assumes all the obligations of the
Company under its Note Guarantee, this Indenture and the Security Documents
pursuant to agreements in form and substance satisfactory to the Trustee; (c)
immediately after such transaction no Default or Event of Default has occurred
and is continuing, unremedied and unwaived; and (d) the Company or the Person
formed by or surviving any such consolidation or merger (if other than the
Company), or to which such sale, assignment, transfer, conveyance or other
disposition shall have been made will, immediately after such transaction and
after giving pro forma effect thereto and any related financing transactions as
if the same had occurred at the beginning of the applicable four-quarter period,
(i) be permitted to Incur at least $1.00 of additional Indebtedness pursuant to
the first paragraph of Section 4.09 hereof or (ii) not have a higher
Consolidated Leverage Ratio than the Consolidated Leverage Ratio of the Company
and its Restricted Subsidiaries immediately prior to such sale, assignment,
transfer, conveyance or other disposition. The Company will not, directly or
indirectly, lease all or substantially all of its Property, in one or more
related transactions, to any other Person. The provisions of this Section 5.01
will not be applicable to a sale, assignment, transfer, conveyance or other
disposition of Property between or among the Company and the other Credit
Parties.

          SECTION 5.02. Successor Entity Substituted.

          Upon any consolidation or merger, or any sale, assignment, transfer,
lease, conveyance or other disposition described in Section 5.01 hereof, the
successor entity formed by such consolidation or into or with which the Company
is merged or to which such sale, assignment, transfer, lease, conveyance or
other disposition is made shall succeed to, and be substituted for (so that from
and after the date of such consolidation, merger, sale, lease, conveyance or
other disposition, the provisions of this Indenture and the Security Documents
referring to the Company shall refer instead to the successor entity and not to
the Company), and may exercise every right and power of the Company under this
Indenture and the Security Documents with the same effect as if such successor
Person had been named as the Company herein and therein; provided that the
predecessor Company shall not be relieved from its obligations in respect of the
Notes or the Note Guarantee, as applicable, except in the case of a sale of all
of the Company's and its Restricted Subsidiaries' Property that meets the
requirements of Section 5.01 hereof.

                          ARTICLE VI SECURITY DOCUMENTS

          SECTION 6.01. Collateral and Security Documents.

          (a) Execution of Security Documents. On the Issue Date, the Credit
Parties and the Trustee (and, to the extent contemplated in Section 11.05, the
Belgian Floating Charge Lienholder), for the benefit of itself and the Holders,
will enter into the Global Security Agreement, and such other security
agreements, pledge agreements, assignments, mortgages or other similar
instruments or documents as shall be necessary to create, perfect and make
enforceable Liens upon the Property subject to the Lien of the Global Security
Agreement as provided in the last paragraph of Section 3 of the Global Security
Agreement (but subject to Sections 6.02 and 6.03 hereof), in order that the
Trustee shall enjoy, for the benefit of the Trustee and the Holders, a Lien on
substantially all of the Property of the Credit Parties described in the
definition of "Collateral" in Section 1.01 hereof, now existing or hereafter
arising, and wherever located (or, in the case of the floating charge in Belgium
referred to in Section 11.05(a) hereof, Liens in favor of the Belgian Floating
Charge Lienholder securing the Parallel Debt referred to in said Section
11.05(a)). Concurrently with the execution and delivery of the agreements,
assignments, mortgages and other instruments or documents referred to above, the
Credit Parties will, in accordance with the requirements of Exhibit F furnish to
the Trustee Opinions of Counsel, documents and instruments, and will take the
actions, identified on Exhibit F hereto, each of which shall be deemed
reasonably satisfactory to the Holders unless the Trustee receives notification
to the contrary.

          The Trustee and the Credit Parties hereby acknowledge and agree that
the Trustee holds the Collateral in trust for the benefit of the Trustee and the
Holders, in each case pursuant to the terms of this Indenture and the Security
Documents. The Trustee is hereby appointed and authorized to act as agent on
behalf of and in the name of the Holders in connection with the Security
Documents and the Collateral, including taking,

                                    Indenture

<PAGE>

                                      -73-

managing, releasing and enforcing security, and any and all matters incidental
or related thereto; and each Holder, by accepting a Note, shall be deemed to
have agreed to such appointment and authorization. Each Holder, by accepting a
Note, shall be deemed to have agreed to all the terms and provisions of the
Security Documents.

          (b) Equal and Ratable Lien. As among the Holders, the Collateral shall
be held for the equal and ratable benefit of the Holders without preference,
priority or distinction of any thereof over any other.

          (c) Use of Collateral. In the absence of notice to the Issuer of a
continuing, unremedied and unwaived Event of Default and subject to the
provisions of this Indenture and the applicable Security Documents, the Credit
Parties shall be suffered and permitted to possess, divest, charter, lease, use,
manage, operate and enjoy the Collateral and all rights appurtenant thereto
(other than any (i) Cash Collateral constituting part of the Collateral and
deposited or required to be deposited with the Trustee in (w) the Specified
Subsidiary Asset Sale Proceeds Account, (x) the Asset Sale Proceeds Account, (y)
the Specified Subsidiary Casualty Event Proceeds Account or (z) for any payment
on or redemption or purchase of any Notes and (ii) Possessory Collateral to the
extent not otherwise permitted under this Indenture or applicable Security
Documents).

          (d) Authorization to Trustee. Each Holder, by accepting a Note,
authorizes and directs the Trustee to enter into the Intercreditor Agreement and
each of the Security Documents contemplated hereby and to perform all of the
obligations of the Trustee thereunder.

          (e) General Notification Agreement. Each Credit Party agrees on the
Issue Date to become a party to a General Notification Agreement in
substantially the form of Exhibit H hereto, and thereafter whenever a Subsidiary
shall become a Guarantor hereunder to cause such Subsidiary to similarly become
a party to such General Notification Agreement.

          SECTION 6.02. Exclusion of Certain Liens.

          Notwithstanding anything in Section 6.01 or 6.03 hereof (except as
otherwise provided in clauses (i) through (vi) of Section 6.03(a)) or in any of
the Security Documents to the contrary (but without limiting the obligation of
each Credit Party to execute and deliver the Global Security Agreement), the
Credit Parties shall not be required to take any action to create, perfect and
make enforceable any Lien on any Property of any Credit Party in any
jurisdiction outside of the United States to the extent that any of the
following conditions shall be applicable, the determination of such
applicability to be (x) deemed acceptable to the Holders unless the Trustee
receives notification to the contrary, and (y) made by the Company with respect
to any such determination to be made after the Issue Date, it being understood
that if the Company shall determine after the Issue Date that any of such
conditions are applicable with respect to any Property of any Credit Party in
any jurisdiction acquired after the Issue Date, the Company shall deliver an
Officers' Certificate to such effect to the Trustee

<PAGE>

                                      -74-

identifying the Property as to which such condition is applicable and the basis
upon which such determination has been made:

          (i) the taking of such action to create, perfect or make enforceable
     such Lien with respect to such Property is (x) prohibited under applicable
     law, or (y) requires that a governmental or regulatory approval or
     registration (other than merely ministerial acts, notices and the like) or
     a third party consent be obtained, which approval, registration or consent
     has not yet been obtained or has been denied; provided that each Credit
     Party agrees to use its commercially reasonable efforts to obtain any such
     governmental or regulatory approval, registration or third party consent on
     or before the Issue Date (with respect to any such Property owned by it on
     the Issue Date), and as promptly as practicable thereafter (with respect to
     any such Property owned by it on the Issue Date if governmental approval or
     third party consent has not been obtained on the Issue Date, and with
     respect to Property acquired by it after the Issue Date), it being
     understood that the failure, after expending commercially reasonable
     efforts, to so obtain an approval or consent shall not constitute an Event
     of Default hereunder;

          (ii) any of the following conditions shall exist, namely (x) no law is
     applicable to the taking of a Lien on such Property (such as with respect
     to undersea cables in international waters) or (y) applicable law requires
     a metes and bounds description (or equivalent) in order to create, perfect
     or make enforceable a Lien on such Property and it is not practicable to
     prepare such a description; provided that to the extent that a generic
     description of such Property may be sufficient to create, perfect or make
     enforceable such Lien and thereby gain priority over certain creditors of
     the Credit Party (even though such Lien would not be enforceable against
     all creditors to the same extent as a Lien under the Uniform Commercial
     Code is enforceable against creditors with respect to Property in the
     United States of a debtor located in the United States), such Credit Party
     will nevertheless take such action as shall be appropriate to create,
     perfect and make enforceable such Lien against such smaller category of
     creditors;

          (iii) the aggregate cost of obtaining and maintaining a Lien upon the
     Property (other than real property or real property interests) of such
     Credit Party and other Credit Parties in such jurisdiction through the
     Stated Maturity of the Notes (including all recording and stamp fees,
     taxes, notary fees and local counsel legal expenses, but excluding fees of
     any Credit Party's counsel other than local counsel in the jurisdiction of
     any such Lien or Property, New York counsel to the Trustee and the Holders
     and any costs that arise at the time of the enforcement of such Lien) is
     (A) reasonably estimated to exceed 5% of the aggregate Fair Market Value of
     the Property of such Credit Party located in such jurisdiction; provided
     that the foregoing shall not be applicable to any jurisdiction to the
     extent that such costs shall not be greater than $80,000 with respect to
     Liens being taken in such jurisdiction on the Issue Date, or not be greater
     than $80,000 during any calendar year with respect to Liens being taken in
     such jurisdiction after the Issue Date and (B) such Property is immaterial
     in relation to the aggregate value of the Property

                                    Indenture

<PAGE>

                                      -75-

     of all of the Credit Parties in which the Trustee is obtaining a valid,
     perfected and enforceable Lien and is not a necessary link or equipment
     (assuming no cable or fiber capacity or rights thereto are available from
     any other provider) to enable any Material Subsidiary to conduct any
     material portion of its operations or business and

          (iv) such Property consists of a parcel of real property or real
     property interests and the aggregate cost of obtaining and maintaining a
     Lien upon such Property in such jurisdiction through the Stated Maturity of
     the Notes (including all recording and stamp fees, taxes, notary fees and
     local counsel legal expenses, but excluding fees of New York counsel to the
     Trustee and the Holders and any costs that arise at the time of the
     enforcement of such Lien) are reasonably estimated to exceed 5% of the
     aggregate Fair Market Value of such parcel and shall be greater than
     $80,000 with respect to Liens being taken in such jurisdiction on the Issue
     Date, and greater than $80,000 during any calendar year with respect to
     Liens being taken in such jurisdiction after the Issue Date, or greater
     than $30,000 for any individual parcel of Property (such latter estimate to
     be taken as an average of the costs of taking Liens on all parcels of real
     property or real property interests in the respective jurisdiction on the
     Issue Date and thereafter, and not on the cost of obtaining a Lien on any
     particular parcel in such jurisdiction) and such Property is immaterial in
     relation to the aggregate value of the Property of all of the Credit
     Parties in which the Trustee is obtaining a valid, perfected and
     enforceable Lien and is not a necessary link (assuming no cable or fiber
     capacity or rights thereto are available from any other provider) to enable
     any Material Subsidiary to conduct any material portion of its operations
     or business; and

provided, however, that:

          (x) in the event that any Credit Party shall take action to create,
     perfect or make enforceable Liens in favor of any Working Capital Facility
     on Property of any Credit Party in any jurisdiction, the foregoing
     conditions shall be deemed inapplicable to such Property;

          (y) none of the foregoing conditions shall be applicable to the taking
     of any Lien in Possessory Collateral, or in the Equity Interests of any
     Issuer under and as defined in the Global Security Agreement or, after the
     occurrence and during the continuance of an unremedied and unwaived Event
     of Default and delivery of notice thereof to the Issuer, Cash Collateral
     not held in the Asset Sale Proceeds Account, the Specified Subsidiary Asset
     Sale Proceeds Account or the Specified Subsidiary Casualty Event Proceeds
     Account and

          (z) so long as no Event of Default shall have occurred and be
     continuing, unremedied and unwaived, the Credit Parties shall not be
     required to take any action to create, perfect and make enforceable any
     Lien in Cash Collateral (other than any Cash Collateral held in the Asset
     Sale Proceeds

     Specified Subsidiary Casualty Event Proceeds Account); provided, however,
     that the Credit Parties will create Liens on Cash Collateral only to the
     extent of a floating charge, blanket lien or similar filing which does not
     provide the Trustee with any ability to exercise any control over or
     dominion of the Cash Collateral prior to the occurrence and continuance of
     an Event of Default that is unremedied and unwaived.

          In determining under this Section 6.02 whether a Lien may be created,
perfected or made enforceable with respect to any Property in any particular
jurisdiction, the Credit Parties acknowledge that it is not the intent of this
Section 6.02 to dispense with the requirement that action be taken with respect
to a Lien simply because there may be qualifications or exceptions to the Liens
taken, or because there may be qualifications or exceptions to any required
opinion of counsel in the applicable jurisdiction by reason of legal
uncertainties as to the manner in which a Lien is to be taken, as to the
applicable law or for any other reason. In addition, to the extent that,
although there may be uncertainty under applicable local law as to the manner in
which to create, perfect or make enforceable a Lien on any Property, there is an
accepted practice in the relevant jurisdiction that is typically undertaken to
take a Lien on such Property, it is nevertheless the intent of the Credit
Parties that the actions and Security Documents customarily adopted in such
jurisdiction shall be taken and executed, as applicable. Without limiting the
generality of the foregoing, it is recognized by the parties that Liens in
certain countries (such as Mexico, Colombia, Venezuela or Argentina) may be
granted to creditors not through a direct pledge, but through a transfer of
title in Property to a trustee, such as under a fideicomiso, and that creating,
perfecting and making enforceable a Lien in such manner is agreed to be an
acceptable method of taking a Lien on Property in any jurisdiction. The parties
hereto also recognize that it may be necessary in certain countries to appoint a
local trust company to act as a trustee in such country or countries for the
Holders.

          For purposes of clause (i) of the first paragraph of this Section
6.02, notwithstanding that a Lien may to a certain extent or in certain
circumstances be prohibited under applicable law, the respective Credit Party
shall nevertheless take action to create, perfect and make enforceable such Lien
if the relevant Security Document states that such Lien is being taken "to the
maximum extent permitted under applicable law" (or words of similar import),
unless such Credit Party delivers an Opinion of Counsel from the respective
jurisdiction that such a qualification in such Security Document would be
ineffective for purposes of avoiding a violation of law.

          For purposes of clauses (iii) and (iv) of the first paragraph of this
Section 6.02, the term "jurisdiction" shall refer to a country (such as Canada
or Mexico) and not to the particular provinces, States or other political
subdivisions within such country.

                                    Indenture

                                      -77-

          SECTION 6.03. Maintenance of Liens.

          (a) Maintenance and Preservation of Liens. The Credit Parties will
(subject to Section 6.02 hereof) take or cause to be taken all action required
to maintain, preserve and protect the Liens on the Collateral granted by the
Security Documents, including causing any Security Document, instruments of
further assurance and all amendments or supplements thereto, to be promptly
recorded, registered and filed and at all times (except as otherwise permitted
to be released pursuant to this Indenture or applicable Security Documents) to
be kept recorded, registered and filed, and will execute and file statements and
cause to be issued and filed statements, all in such manner and in such places
and at such times as are prescribed in the Security Documents or in this
Indenture and as may be required by law to fully preserve and protect the rights
of the Holders and the Trustee under this Indenture and the Security Documents
to the Collateral. In that connection, it is understood and agreed that:

          (i) as to Property of any Credit Party located in any jurisdiction
     owned by such Credit Party on the Issue Date that is not covered by the
     Lien of a particular Security Document other than the Global Security
     Agreement, such Credit Party shall be deemed to have complied with the
     requirements of this paragraph if, as contemplated by Exhibit F hereto,
     unless the initial Holders of the Notes shall have given notice to the
     Trustee that the conditions set forth in said Exhibit F have not been
     satisfied;

          (ii) as to Property of any Credit Party located in any jurisdiction,
     whether now owned or hereafter acquired, that is covered by the Lien of a
     particular Security Document other than the Global Security Agreement (or
     that is contemplated by such Security Document to be covered by such Lien
     if acquired after the Issue Date), such Credit Party shall be deemed to
     have complied with the requirements of this paragraph if such Credit Party
     complies with the requirements of such Security Document;

          (iii) as to all other Property hereafter acquired by any Credit Party,
     such Credit Party shall (subject to Section 6.02) comply with the
     requirements of this paragraph (except with respect to Property in any
     jurisdiction to the extent that a Security Document expressly provides that
     the respective Credit Party need not take action to create, perfect or make
     enforceable a Lien with respect to such Property);

          (iv) as to any contract or agreement to which any Credit Party is a
     party on the Issue Date that requires the consent of a third party in order
     to create a lien in such contract or agreement, such Credit Party shall be
     deemed to have complied with the requirements of this paragraph if, after
     utilizing commercially reasonable efforts to so obtain such consent, as
     contemplated by Exhibit F hereto, unless the initial Holders of the Notes
     shall notify the Trustee that the conditions set forth in said Exhibit F
     have not been satisfied;

                                    Indenture

<PAGE>

                                      -78-

          (v) as to any contract or agreement to which any Credit Party becomes
     a party after the Issue Date that requires the consent of a third party in
     order to create a lien in such contract or agreement, such Credit Party
     shall be deemed to have complied with the requirements of this paragraph,
     notwithstanding that such consent has been refused, if it shall have used
     commercially reasonable efforts to obtain such consent (and shall so
     certify in the first Officers' Certificate delivered pursuant to paragraph
     (c)(ii)(B) below after the date of such refusal); and

          (vi) as to any portion of the cable network and its related equipment
     in the Netherlands that is deemed to be immovable Property under Dutch law,
     the Credit Parties shall not be required to create and grant any mortgage
     on any such Property until such Property has been registered in the Public
     Register of The Netherlands.

          Without limiting the generality of the foregoing, if after the Issue
Date the Company or any of its Restricted Subsidiaries shall create, incur,
assume or otherwise cause or suffer to exist or become effective any Lien of any
kind upon any of its Property to secure any Working Capital Facility (which
Property is not already subject to the Lien of the Security Documents or to
perfection thereunder), the Company shall, or shall cause such Restricted
Subsidiary to, as the case may be, (i) execute and file, as applicable, any and
all further Security Documents and other instruments required under applicable
law, upon substantially the same terms as the security documents securing a
Working Capital Facility, as shall be necessary to effectuate a Lien subject to
any Working Capital Facility and the Permitted Liens referred to in clauses (e),
(h), (i), (j), (k), (l), (m), (n) and (o) of the definition of such term in
Section 1.01 hereof upon such Property for the benefit of the Holders, unless
such Lien cannot be effectuated under applicable law and (ii) deliver an Opinion
of Counsel reasonably satisfactory to the Trustee that such Security Documents
are valid, binding and enforceable obligations, it being understood that in no
event will any Working Capital Facility be entitled to the benefit of any Liens
on any of the Indenture Exclusive Collateral.

          (b) Recording and Filing Fees. The Credit Parties will, from time to
time promptly pay and discharge all recording or filing fees, charges and taxes
relating to the filing or registration of this Indenture and the Security
Documents, any amendments thereto and any other instruments of further
assurance.

          (c) Confirmatory Action Regarding Liens. The Credit Parties will
furnish to the Trustee:

          (i) without limiting the provisions of Exhibit F hereto with respect
     to documents to be delivered on the Issue Date (which provisions shall
     govern documents to be delivered on the Issue Date) and subject to Section
     6.02 hereof, promptly after the execution and delivery of this Indenture,
     the Security Documents, each amendment or supplement to a Security Document
     or other instrument of further assurance, an Opinion or Opinions of Counsel
     stating that, in the opinion of such counsels, this Indenture, the Security
     Documents, any such

                                    Indenture

<PAGE>

                                      -79-

     amendment or supplement to a Security Document and other instruments of
     further assurance have been properly recorded, endorsed, registered and
     filed, or have been received by the applicable governmental authority for
     recording, filing or registration, to the extent necessary (but subject to
     Section 6.02 hereof) to make effective and perfect the Liens intended to be
     created by this Indenture and the Security Documents and reciting the
     details of such action or referring to prior Opinions of Counsel in which
     such details are given, or stating that, in the opinion of such counsel, no
     such action is necessary to make such Liens effective;

          (ii) on or before February 28 in each year beginning with February 28,
     2005, (A) an Opinion or Opinions of Counsel, dated as of a date not earlier
     than 60 days prior to such date, either stating that, in the opinion of
     such counsels, such action has been taken with respect to the recording,
     registering, filing, re-recording, re-registering and re-filing of this
     Indenture, the Security Documents, of all amendments or supplements to the
     Security Documents, financing statements, continuation statements or other
     instruments of further assurances as is necessary (but subject to Section
     6.02 hereof) to maintain the Lien of the Security Documents (including the
     Lien on any Property acquired by the Issuer or any Guarantor since the end
     of the preceding calendar year) to the extent required under the provisions
     of the applicable Security Documents and the provisions of this Article VI,
     and reciting the details of such action or referring to prior Opinions of
     Counsel in which such details are given, or stating that, in the opinion of
     such counsel, no such action is necessary to maintain such Lien and (B) an
     Officers' Certificate of the Issuer, dated as of a date not earlier than 60
     days prior to such date, stating that all fees required to be paid under
     each Security Document have been paid and that the Credit Parties have used
     commercially reasonable efforts to obtain any consent referred to in clause
     (v) of paragraph (a) above; and

          (iii) from time to time, notice of any recording, registration,
     filing, payment or other action taken in accordance with the provisions of
     Section 6.03(a) hereof, in each case as promptly as practicable after
     taking any such action.

          The Credit Parties will comply with Section 314(b) of the TIA.

          (d) Insurance. The Company will cause all casualty insurance
maintained by the Company or any of the other Credit Parties with respect to any
of the Collateral to designate the Trustee as the loss payee thereof (or, in the
case of Shared Collateral, to designate the agent under a Working Capital
Facility as loss payee, with the Trustee being designated as an additional
insured), as its interests may be, and shall provide copies of certificates for
or endorsements to any such policies (showing such designation) to the Trustee
on the Issue Date and annually thereafter on each February 28, beginning with
February 28, 2005, and shall deliver an Officers' Certificate, together with
copies of appropriate certificates or endorsements, showing that such
designation continues to be in effect; provided that the Company shall not be
required to undertake

                                    Indenture

<PAGE>

                                      -80-

any of the foregoing with respect to any insurance policies maintained by a
Credit Party (x) for the benefit of any governmental authority as required by
law or (y) covering Motor Vehicles.

          (e) Amendments to Security Documents. The Company will not, and will
not permit any Restricted Subsidiary thereof to, take or omit to take any action
which action or omission might or would have the result of impairing the Lien
with respect to the Collateral for the benefit of the Trustee and the Holders,
and the Company shall not, and shall not permit any Restricted Subsidiary
thereof to, grant to any Person other than the Trustee, for the benefit of the
Trustee and the Holders, any interest whatsoever in any of the Collateral,
except as expressly permitted under this Indenture and the Security Documents;
provided that nothing herein shall be deemed to prohibit any amendment,
modification or supplement of this Indenture or any Security Document (i) in
order to effectuate the subordination of the Lien of the Trustee and the Holders
under the Security Documents to any Lien securing a Working Capital Facility as
contemplated by Section 6.04 hereof or (ii) in connection with the release by
the Trustee of any Lien upon any Property of the Company or any Restricted
Subsidiary thereof that is the subject of a sale or other disposition (including
any Asset Sale or any Specified Subsidiary Asset Sale) permitted hereunder or
under the Security Documents, to the extent such release is required pursuant to
Section 6.05 hereof.

          SECTION 6.04. Subordination to Working Capital Facilities.

          The Liens created pursuant to the Security Documents shall be subject
to no other Lien other than (a) in the case of any Collateral, Permitted Liens
referred to in clauses (e), (h), (i), (j), (k), (l), (m), (n) and (o) of the
definition of such term in Section 1.01 hereof and (b) in the case of the Shared
Collateral, Liens securing the obligations of the Credit Parties under and in
respect of any Working Capital Facility. In the event that the Company or any of
its Restricted Subsidiaries shall at any time Incur Indebtedness in respect of
any Working Capital Facility and such Indebtedness shall be secured by any of
the Property of the Company or any of its Restricted Subsidiaries, the Trustee
shall, upon receipt of an Issuer Order to such effect, execute and deliver an
Intercreditor Agreement in substantially the form of Exhibit C hereto, together
with such other documents and instruments as shall be necessary, and to the
maximum extent permitted under applicable law, to effect the subordination of
the Liens of the Security Documents to the Liens securing such Working Capital
Facility, insofar as relating to the Shared Collateral, in each case to the
extent set forth in an Issuer Order and an Opinion of Counsel. Each Holder, by
acceptance of the Notes, agrees to be bound by the provisions of the
Intercreditor Agreement upon execution and delivery thereof.

          SECTION 6.05. Release of Liens.

          (a) Releases Generally. Subject to paragraphs (b), (c) and (d) of this
Section 6.05 hereof, Collateral may be released from the Lien and security
interest created by the Security Documents at any time or from time to time in
accordance with the provisions of this Indenture, the Security Documents, the
Intercreditor Agreement, and the Trust Indenture Act. Collateral shall be
released at any time that the Notes have

                                    Indenture

<PAGE>

                                      -81-

been irrevocably paid in full or otherwise irrevocably discharged pursuant to
the terms of this Indenture.

          (b) Releases upon Issuer Request. So long as no Default or Event of
Default shall have occurred and be continuing unremedied and unwaived, or would
be caused thereby, upon the request of the Issuer pursuant to an Issuer Request,
accompanied by an Officers' Certificate certifying, that all conditions
precedent to such release hereunder have been met, and without the consent of
any Holder, the Credit Parties will be entitled to release of Property included
in the Collateral from the Liens securing the Notes under any one or more of the
following circumstances:

          (i) to enable the Issuer or any Guarantor to consummate any sale,
     lease, conveyance or other disposition (including by way of merger or
     consolidation) of any Property in compliance with and not prohibited by
     Articles IV and V hereof, and any other provision hereunder; provided that
     (A) all other Liens on such Property securing any Working Capital Facility
     are similarly released and (B) only the Property issued, sold, leased,
     conveyed or otherwise disposed (including by way of merger or
     consolidation) is subject to such release;

          (ii) to permit a Credit Party to incur and suffer to exist any
     Permitted Lien on Property described under clauses (k), (m) or (o) of the
     definition of "Permitted Liens" in Section 1.01 hereof, if (A) such
     Permitted Lien would not be prohibited under Article IV hereof or any other
     provision hereunder, (B) the release of such Lien is reasonably necessary
     to effect any such Permitted Lien, (C) such release does not extend to any
     Property other than that subject to such Permitted Lien and (D) all Liens
     on such Property securing Obligations under all Working Capital Facilities
     are released;

          (iii) if, in compliance with Section 4.18 hereof, the Company shall
     designate a Restricted Subsidiary as an Unrestricted Subsidiary, such
     Subsidiary shall be released from its obligations under its Note Guarantee
     and from the Lien created by this Indenture and the Security Documents;
     provided that all guarantees of such Subsidiary in favor of any Working
     Capital Facility, and all Liens on such Property securing all Working
     Capital Facilities, are released;

          (iv) pursuant to an amendment, supplement or waiver entered into in
     accordance with Article 9 hereof; and

          (v) pursuant to a Qualified Lien Release.

          In the case of any release of Collateral from the Liens securing the
Notes in accordance with one or more of the foregoing clauses in this paragraph
that constitutes an Asset Sale or Specified Subsidiary Asset Sale, it shall also
be a condition precedent to any release that, (x) the Company shall have
delivered an Officers' Certificate to the Trustee setting forth the aggregate
amount of the Net Cash Proceeds to be received upon such Asset Sale or Specified
Subsidiary Asset Sale, (y) the Trustee shall have receipt of

                                   Indenture

<PAGE>

                                      -82-

such Net Cash Proceeds for deposit into the Specified Subsidiary Asset Sale
Proceeds Account or the Asset Sale Proceeds Account, as applicable and (z) the
Company shall have taken all actions necessary to create, perfect and make
enforceable the Lien on any other consideration received in connection with such
Asset Sale or Specified Subsidiary Asset Sale.

          Upon receipt of such required Officers' Certificate or Officers'
Certificates, as the case may be, and any required Opinion of Counsel, pursuant
and subject to the provisions of this Section 6.05 hereof, the Collateral Agent
shall execute, deliver or acknowledge, at the expense of the Credit Parties, any
reasonably necessary or proper instruments of termination, satisfaction or
release to evidence the release (prepared by the Issuer or the Company) of any
Collateral permitted to be released (and the release of any Guarantee, if
applicable) pursuant to this Indenture, the Intercreditor Agreement and the
Security Documents.

          (c) No Impairment of Continuing Security. The release of any
Collateral from the Lien of the Security Documents will not be deemed to impair
the security under this Indenture in contravention of the provisions hereof, if
and to the extent Collateral is released pursuant to the terms hereof and of the
Security Documents. Notwithstanding anything to the contrary contained herein,
the Company and its Restricted Subsidiaries are authorized to sell Collateral in
the ordinary course of business free of all Liens of the Trustee and the Holders
under the Security Documents without any action on the part of the Trustee, the
Holders or otherwise; provided that upon receipt by the Trustee of an Issuer
Order requesting confirmation by the Trustee in writing of such release (which
Issuer Order shall be accompanied by an Officers' Certificate in substantially
the form of Exhibit G hereto to the effect that the particular Collateral the
subject of such request was sold in the ordinary course of business), the
Trustee shall so confirm that such Property has been released from the Lien of
the Security Documents. The Trustee shall have no duty or obligation to verify
the facts or statements set forth in the Issuer Order or Officers' Certificate
to be provided to the Trustee in accordance with this Section. In connection
herewith, the Company agrees that, unless not required by the TIA, every
February 28 and August 31 of each year commencing February 28, 2004 after the
Issue Date, the Company shall deliver to the Trustee, on behalf of the Holders,
an Officers' Certificate stating that all sales of Collateral in the six months
preceding the date of delivery of such certificate either (i) were in the
ordinary course of business or (ii) otherwise complied with the terms of this
Section 6.05, the other terms of this Indenture and the Security Documents and
the terms of the TIA.

          (d) Compliance with TIA. The Issuer will cause TIA Section 313(b)
(including the provisions thereof relating to the delivery of reports), and TIA
Section 314(d) (including the provisions thereof relating to the release of
property or securities from the Lien and security interest of the Security
Documents), to be complied with. Any certificate or opinion required by Section
314(d) of the Trust Indenture Act may be made by any Officer of the Issuer or
the Company; provided that, to the extent required by Section 314(d) of the
Trust Indenture Act, any such certificate or opinion shall be

                                   Indenture

<PAGE>

                                      -83-

made by an "independent appraiser" or other "expert" (as such terms are set
forth in Section 314(d) of the Trust Indenture Act).

          SECTION 6.06. Collateral Agent.

          (a) Trustee Acting as Collateral Agent. The Trustee shall act as
Collateral Agent and shall be authorized to appoint co-Collateral Agents as
necessary in its sole discretion. The Collateral Agent shall be accountable only
for amounts that it actually receives as a result of the exercise of such
powers, and neither the Collateral Agent nor any of its officers, directors,
employees or agents shall be responsible for any act or failure to act
hereunder, except for its own negligence or willful misconduct. For so long as
the Trustee shall act as Collateral Agent hereunder, the Collateral Agent shall
be afforded the same rights, protections, immunities and indemnities provided
the Trustee herein. The Trustee shall not be liable for the acts, omissions,
fees or expenses of any co-Collateral Agent appointed by it with due care. The
Credit Parties agree to pay the fees and expenses of any such co-Collateral
Agents.

          (b) Authorization to Collateral Agent. The Trustee, as Collateral
Agent, is authorized and directed to (i) enter into the Security Documents, (ii)
enter into the Intercreditor Agreement, (iii) bind the Holders on the terms as
set forth in this Indenture, the Security Documents and the Intercreditor
Agreement and (iv) perform and observe its obligations under this Indenture, the
Security Documents and the Intercreditor Agreement.

          (c) Release Certificates of the Trustee. In the event that the Issuer
wishes to release Collateral in accordance with this Indenture and the Security
Documents at a time when the Trustee is not itself also the Collateral Agent,
the Trustee will determine whether it has received all documentation required by
this Indenture in connection with such release and, based on such determination,
will deliver a certificate to the Collateral Agent setting forth such
determination.

          (d) Termination of Security Interest. Upon payment or irrevocable
discharge in accordance with the terms of this Indenture in full of the
principal of, premium, if any, and accrued and unpaid interest on the Notes and
all other Obligations under this Indenture, the Note Guarantees and the Security
Documents that are due and payable at or prior to the time such principal,
premium, if any, and accrued and unpaid interest are paid, including pursuant to
the last paragraph of Section 4.01 hereof and Section 8.07 hereof, in the event
that the Trustee is not itself also the Collateral Agent, the Trustee will, at
the request of the Issuer, deliver a certificate to the Collateral Agent stating
that such Obligations have been paid in full or otherwise irrevocably discharged
in accordance with the terms of this Indenture, and instruct the Collateral
Agent to release and terminate the Liens granted pursuant to the Security
Documents.

          SECTION 6.07. Trustee in its Individual Capacity.

          The parties hereto acknowledge that the Trustee is executing certain
of the Security Documents in its individual capacity, and not as Trustee for the
benefit of the

                                   Indenture

<PAGE>

                                      -84-

Holders under this Indenture. Accordingly, the parties hereto agree that with
regard to such Security Documents the Trustee, acting in such individual
capacity, shall be subject to the duties and responsibilities of the Trustee and
receive the benefits of the indemnities set forth in this Indenture.

                        ARTICLE VII DEFAULT AND REMEDIES

          SECTION 7.01. Events of Default.

          The following events shall, so long as the same shall have occurred
and be continuing, constitute an "Event of Default" hereunder:

          (a) default for 30 or more successive days in the payment when due of
     interest on the Notes;

          (b) default in the payment when due (at Stated Maturity, upon
     redemption, upon required repurchase, upon declaration or otherwise) of the
     principal of or premium, if any, on the Notes;

          (c) failure by the Company or any of its Restricted Subsidiaries to
     comply with Section 3.08, 3.09 or 4.15 hereof, or with Article V hereof;

     comply with Section 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.13, 4.14, 4.16,
     4.17 or 4.19 for 20 or more successive days after notice specifying such
     failure shall have been given to the Company by the Trustee or the Holders
     of at least 25% or more in aggregate principal amount of the Notes then
     outstanding;

          (e) failure by the Company or any of its Restricted Subsidiaries for
     45 or more days after notice from the Trustee, or Holders of 25% or more of
     the aggregate principal amount of the Notes, to comply with any of its
     other agreements in this Indenture or any of the Security Documents;

          (f) default in the payment when due (whether at stated maturity, by
     acceleration or otherwise) of any sums 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 by 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 date of this Indenture, to
     the extent that the aggregate amount of Indebtedness in respect of which
     such default occurs is $2,500,000 or more;

          (g) failure by the Company or any of its Restricted Subsidiaries to
     pay final judgments not subject to appeal aggregating in excess of
     $2,500,000 or more (net of applicable insurance coverage which is

     recordation or possession is required herein or therein and is permissible
     or achievable under applicable law) in favor of the Trustee for the benefit
     of the Holders hereunder, free and clear of all other Liens (other than

     jurisdiction, that any such Lien is invalid or unenforceable.

          SECTION 7.02. Acceleration.

          If any Event of Default occurs and is continuing, unremedied and
unwaived, by written notice to the Issuer, the Trustee or the Holders of a
majority in aggregate principal amount of the then-outstanding Notes may declare
the unpaid principal of, premium, if any, accrued and unpaid interest, and any
other amounts due on all the Notes to be due and payable immediately.
Notwithstanding the foregoing, if an Event of Default specified in paragraph (i)
or (j) of Section 7.01 hereof occurs, all outstanding Notes shall be due and
payable immediately without further action or notice. The Holders of a majority
in aggregate principal amount of the then-outstanding Notes by written notice to
the Trustee may on behalf of all of the Holders rescind an acceleration and its
consequences if the rescission would not conflict with any judgment or decree
and if all existing Events of Default (except nonpayment of principal, premium,
if any, or interest that has become due solely because of the acceleration) have
been cured or waived.

          SECTION 7.03. Other Remedies.

          If an Event of Default with respect to outstanding Notes occurs and is
continuing, unremedied and unwaived, the Trustee may pursue any available remedy
to collect the payment of principal of, premium, if any, interest and any other
amounts due, if any, 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 shall not impair the right or remedy or
constitute a waiver of or acquiescence in the Event of Default. All remedies are
cumulative to the extent permitted by law.

          SECTION 7.04. Waiver of Past Defaults.

          Subject to Sections 7.02, 7.07 and 10.02 hereof, Holders of not less
than a majority in aggregate principal amount of the then outstanding Notes by
written 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,
except a continuing Default or Event of Default in the payment of the principal
of, premium, if any, and interest on the Notes

                                   Indenture

<PAGE>

                                      -87-

(including in connection with a required redemption or an offer to purchase).
Upon any such waiver, such Default shall cease to exist, and any Event of
Default arising therefrom shall be deemed to have been cured for every purpose
of this Indenture; but no such waiver shall extend to any subsequent or other
Default or impair any right consequent thereon.

          SECTION 7.05. Control by Majority.

          Holders of a majority in principal amount of the then outstanding
Notes may direct the time, method and place of conducting any proceeding for
exercising any remedy available to the Trustee or exercising any trust or power
conferred on it. However, the Trustee may refuse to follow any direction that
conflicts with law or this Indenture that the Trustee determines may be unduly
prejudicial to the rights of other Holders of Notes or that may involve the
Trustee in personal liability.

          SECTION 7.06. Limitation on Suits.

          A Holder of a Note may pursue a remedy with respect to this Indenture
to the extent it relates to the Notes, this Indenture or the Security Documents
only if:

          (a) the Holder gives to the Trustee written notice of a continuing
     Event of Default and the remedy requested, or the Trustee shall have
     distributed notice of an Event of Default to Holders in accordance with the
     provisions of this Indenture;

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

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

          (d) the Trustee does not comply with the request within 15 days after
     receipt of the request and the offer and any requested provision of
     indemnity; and

          (e) during such 15-day period the Holders of a majority in principal
     amount of the then outstanding Notes do not give the Trustee a direction
     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.

          SECTION 7.07. Rights of Holders of Notes to Receive Payment.

          Notwithstanding any other provision of this Indenture, the right of
any Holder of a Note to receive payment of principal of, premium, if any, and
interest on such Note on or after the respective due dates expressed in such
Note (including in connection

                                   Indenture

<PAGE>

                                      -88-

with a required redemption or an offer to purchase), or to bring suit for the
enforcement of any such payment on or after such respective dates, shall not be
impaired or affected without the consent of such Holder.

          SECTION 7.08. Collection Suit by Trustee.

          (a) Suit Upon Payment Default. If an Event of Default specified in
Section 7.01(a) or (b) hereof occurs and is continuing with respect to the
Notes, the Trustee is authorized to recover judgment in its own name and as
trustee of an express trust against the Issuer and the Guarantors for the whole
amount of principal of, premium, if any, and interest remaining unpaid on the
Notes and interest on overdue principal and, to the extent lawful, interest and
such further amount as shall be sufficient to cover the costs and expenses of
collection, including the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel.

          (b) Suit Generally Upon Default. If an Event of Default occurs and is
continuing, unremedied and unwaived, the Trustee may in its discretion proceed
to protect and enforce its rights and the rights of the Holders by such
appropriate judicial proceedings as the Trustee shall deem most effectual to
protect and enforce any such rights, whether for the specific enforcement of any
covenant or agreement in this Indenture or, in any Security Document, or in aid
of the exercise of any power granted herein or therein, or to enforce any other
proper remedy, subject, however, to Section 7.05 hereof.

          SECTION 7.09. Trustee May File Proofs of Claim.

          The Trustee is authorized to file such proofs of claim and other
papers or documents as may be necessary or advisable in order to have the 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 allowed in any judicial proceedings relative to the Issuer or any
Guarantor (or any other obligor upon the Notes), its creditors or its Property
and shall be entitled and empowered to participate as a member, voting or
otherwise, of any official committee of creditors appointed in such matter and
shall be entitled and empowered to collect, receive and distribute any money or
other Property payable or deliverable on any such claims and any custodian in
any such judicial proceeding is hereby authorized by each Holder to make such
payments to the Trustee, and in the event that the Trustee shall consent to the
making of such payments directly to the Holders, to pay to the Trustee any
amount due to it for the reasonable compensation, expenses and disbursements of
the Trustee, its agents and counsel, and any other amounts due the Trustee under
Section 8.07 hereof. To the extent that the payment of any such compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel, and
any other amounts due the Trustee under Section 8.07 hereof out of the estate in
any such proceeding, shall be denied for any reason, payment of the same shall
be paid out of any and all distributions, dividends, money, securities and other
Property that the Holders may be entitled to receive in such proceeding whether
in liquidation or under any plan of reorganization or arrangement or otherwise.
Nothing herein contained shall be deemed to authorize the Trustee to

                                   Indenture

<PAGE>

                                      -89-

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 7.10. Priorities.

          If the Trustee collects any money with respect to any Notes pursuant
to this Article VII, or pursuant to any of the Security Documents, it shall,
after any application required pursuant to any Intercreditor Agreement, pay out
the money in the following order:

          First: to the Trustee, its agents and attorneys (including the
     Collateral Agent and the Belgian Floating Charge Lienholder) for amounts
     due and payable under Section 8.07 hereof, including payment of all
     compensation, expense and liabilities incurred, and all advances made, by
     the Trustee and the costs and expenses of collection;

          Second: to Holders of 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: to the Credit Parties or to such party as a court of competent
     jurisdiction shall direct.

          The Trustee may fix a Record Date and payment date for any payment to
Holders of Notes pursuant to this Section 7.10.

          SECTION 7.11. Undertaking for Costs.

          In any suit for the enforcement of any right or remedy under this
Indenture or in any suit against the Trustee for any action taken or omitted by
it as a Trustee, a court in its discretion may require the filing by any party
litigant in the suit of an undertaking to pay the costs of the suit, and the
court in its discretion may assess reasonable costs, including reasonable
attorneys' fees, against any party litigant in the suit, having due regard to
the merits and good faith of the claims or defenses made by the party litigant.
This Section 7.11 does not apply to a suit by the Trustee, a suit by a Holder of
a Note pursuant to Section 7.06 hereof, or a suit by Holders of more than 10% in
principal amount of the then outstanding Notes.

          SECTION 7.12. Rights and Remedies Cumulative.

          Except as otherwise provided with respect to the replacement or
payment of mutilated, destroyed, lost or wrongfully taken Notes in Section 2.06
hereof, no right or remedy herein conferred upon or reserved to the Trustee or
to the Holders is intended to be exclusive of any other right or remedy, and
every right and remedy shall, to the extent

                                   Indenture

<PAGE>

                                      -90-

permitted by law, be cumulative and in addition to every other right and remedy
given hereunder or now or hereafter existing at law or in equity or otherwise.
The assertion or employment of any right or remedy hereunder, or otherwise,
shall not prevent the concurrent assertion or employment of any other
appropriate right or remedy.

          SECTION 7.13. Delay or Omission Not Waiver.

          No delay or omission of the Trustee or of any Holder to exercise any
right or remedy accruing upon any Event of Default shall impair any such right
or remedy or constitute a waiver of any such Event of Default or an acquiescence
therein. Every right and remedy given by this Article VII or by law to the
Trustee or to the Holders may be exercised from time to time, and as often as
may be deemed expedient, by the Trustee or by the Holders, as the case may be.

          SECTION 7.14. Restoration of Rights and Remedies.

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

          SECTION 7.15. Power of Attorney for Collateral in Quebec.

          For the purposes of the security on the Collateral located in the
Province of Quebec, Canada, the validity, publication or perfection of which is
governed by the laws of the Province of Quebec, each of the Holders, by
acceptance of the benefits hereof, hereby irrevocably grants to the Trustee, for
the purposes of holding, on behalf of and for the benefit of all present and
future Holders, the Liens granted by any Credit Party covering property located
in the Province of Quebec, a power of attorney within the meaning of Section
2692 of the Civil Code of Quebec (the "Power of Attorney"). The Trustee hereby
accepts such Power of Attorney for the purposes of holding such Liens on behalf
of and for the benefit of all present and future Holders. Without limiting the
generality of the foregoing, to the extent that any Person becomes a Holder by
accepting, purchasing or acquiring a Note, such Person shall be automatically
deemed to have ratified and consented to the Power of Attorney constituted
hereunder. Each Holder, by acceptance of the benefits hereof, agrees that,
notwithstanding the provisions of Section 32 of An Act Respecting the Special
Powers of Legal Persons (Quebec), the Trustee shall not, as the Person holding
the Power of Attorney, be prohibited from acquiring any title to any
indebtedness secured by any hypothec executed in its favor pursuant to this
Indenture or the Notes or any other document contemplated hereunder (including
acquiring for its own account title to any of the Notes issued hereunder).

          SECTION 8.01. General.

          The duties and responsibilities of the Trustee shall be as provided by
the TIA and as specifically set forth herein, and no implied covenants or
obligations shall be read into this Indenture against the Trustee.
Notwithstanding the foregoing, no provision of this Indenture shall require the
Trustee to expend or risk its own funds or otherwise incur any financial
liability in the performance of any of its duties hereunder, or in the exercise
of any of its rights or powers, if it shall have reasonable grounds for
believing that repayment of such funds or adequate indemnity against such risk
or liability is not reasonably assured to it. If an Event of Default has
occurred and is continuing, unremedied and unwaived the Trustee shall exercise
the rights and powers vested in it by this Indenture and the Security Documents
and use the same degree of care and skill in such exercise as a prudent person
would exercise or use under the circumstances in the conduct of such person's
own affairs. Whether or not therein expressly so provided, every provision of
this Indenture relating to the conduct or affecting the liability of or
affording protection to the Trustee shall be subject to the provisions of this
Article VIII. The rights, privileges, immunities and indemnities of the Trustee
set forth in this Article VIII shall apply to the Trustee under each of the
Security Documents as if fully set forth therein.

          SECTION 8.02. Certain Rights of Trustee; Reliance on Certificate.

     refraining from acting, upon any document believed by it to be genuine and
     to have been signed or presented by the proper person and conforming to the
     requirements of this Indenture (and the Trustee need not investigate any
     fact or matter stated in such document);

          (ii) before the Trustee acts or refrains from acting, it may require
     an Officers' Certificate or an Opinion of Counsel, which shall conform to
     Section 12.04 hereof and the Trustee shall not be liable for any action it
     takes or omits to take in good faith in reliance on such certificate or
     opinion;

          (iii) the Trustee may act through its attorneys, agents, custodians
     and nominees (including any agent, including the Collateral Agent, for the
     purpose of holding or foreclosing on Collateral in any jurisdiction) and
     shall not be responsible for the misconduct or negligence of any attorney,
     agent, custodian or nominee appointed with due care;

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

          (v) the Trustee shall not be liable for any action it takes or omits

     or omitted to be taken by it in good faith in accordance with the direction
     of the Holders of at least a majority in aggregate principal amount of the
     Notes at the time outstanding relating to the time, method and place of
     conducting any proceeding for any remedy available to the Trustee or
     involving the exercise of any right, duty, trust or power conferred upon
     the Trustee under the TIA or this Indenture;

     Subsidiary Asset Sale or Specified Subsidiary Casualty Event, or (D) any
     default under any Security Documents unless the Trustee shall have received
     written notice thereof from the Issuer or any Holder;

          (viii) in no event shall the Trustee be liable for any failure or
     delay in the performance of its obligations hereunder because of
     circumstances beyond the Trustee's control, including, but not limited to,
     acts of God, flood, war (whether declared or undeclared), terrorism, fire,
     riot, embargo, government action, including any laws, ordinances,
     regulations, governmental action or the like which delay, restrict or
     prohibit the providing of the services contemplated by this Indenture;

          (ix) in the absence of bad faith on the part of the Trustee, the
     Trustee may conclusively rely and shall be fully protected in acting or
     refraining from acting upon any resolution, certificate, statement,
     instrument, opinion, report, notice, request, consent, order, approval or

     been signed or presented by the proper party or parties and shall not be
     required to investigate or verify the facts or matters stated therein;

          (x) the Trustee shall 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 or acted with willful
     misconduct;

     subject to the provisions of the TIA as they relate to this Indenture, in
     no event shall the Trustee be liable for special, indirect or consequential
     loss or damage of any kind whatsoever (including but not limited to lost
     profits), even if the Trustee has been advised of the likelihood of such
     loss or damage regardless of the form of action;

          (xii) the Trustee shall not be bound to make any investigation into

     stated maturity or the failure of a secured party to provide timely written
     investment direction;

     respect to the preparation, execution or filing of any report or
     certification to be delivered to the SEC with respect to the Issuer;

          (xv) in the absence of bad faith on the part of the Trustee, the
     Trustee may conclusively rely, as to the truth of the statements and the
     correctness of the opinions expressed therein, upon any certificates or
     opinions furnished to the Trustee which conform to the requirements of this
     Indenture;

          (xvi) the Trustee may consult with counsel and the advice or any
     opinion of counsel shall be full and complete authorization and protection
     in respect of any action taken or omitted by it hereunder in good faith and
     in accordance with such advice or opinion of counsel; provided that the
     Trustee's conduct does not constitute negligence or willful misconduct;

          (xvii) except as expressly instructed by the Holders of the Notes or
     the Issuer or any other Credit Party as contemplated in this Indenture and
     the Security Documents, the Trustee shall (x) have no obligation to give,
     execute, deliver, file, record, authorize or obtain any financing
     statements, notices, instruments, documents, agreements, consents or other

          (xviii) the Trustee is hereby authorized to provide powers of attorney
     to such Persons as it deems necessary and desirable to fulfill its
     obligations under this Indenture and the Security Documents and in no event
     shall the Trustee be liable for the acts or omissions of such Persons in

          (b) Instructions by Beneficial Owners of Notes. Notwithstanding the
provisions of the foregoing paragraph (a), the Trustee, in receiving
instructions of Holders, shall be entitled to conclusively rely and shall follow
the instruction of any Person that it reasonably believes to be a Beneficial

Holders, shall consent to such action, in which event any certificate filed
under any of such Sections shall omit the statement to the effect that no
Default or Event of Default has occurred and is continuing, unremedied and
unwaived. This Section 9.05 shall not apply, however, during the continuance of
an Event of Default of the type specified in Section 7.01(i) or (j) hereof.

          SECTION 9.06. Powers Exercisable by Trustee or Receiver.

          In case the Collateral (other than any Cash Collateral, Possessory
Collateral and other Property held by, or required to be deposited or pledged
with the Trustee hereunder or under the Security Documents) shall be in the
possession of a receiver or trustee lawfully appointed, the powers hereinbefore
in this Article IX conferred upon the Credit Parties with respect to the
withdrawal or application of Trust Moneys may be exercised by such receiver or
trustee, in which case a certificate signed by such receiver or trustee shall be
deemed the equivalent of any Officers' Certificate required by this Article IX.
If the Trustee shall be in possession of any of the Collateral hereunder or
under the Security Documents, such powers may be exercised by the Trustee in its
discretion (it being understood that the Trustee shall have no obligation to
exercise such powers).

          SECTION 9.07. Disposition of Notes Retired.

          All Notes received by the Trustee and for whose purchase Trust Moneys
are applied under this Article IX, if not otherwise cancelled, shall be promptly
cancelled and disposed of by the Trustee pursuant to Section 2.09 hereof.

          SECTION 9.08. Investment and Use of Trust Moneys.

          (a) Investment of Trust Moneys. All or any part of any Trust Moneys
held by the Trustee hereunder shall from time to time be invested by the
Trustee, upon the specific instructions of the Company, in Qualified Cash
Equivalents, and any interest on such investments which may be received by the
Trustee shall be retained by the Trustee as Trust Moneys. Such deposits shall be
held by the Trustee as a part of the Collateral, subject to the same provisions
hereof. The Trustee shall not be liable or responsible for any loss resulting
from such deposits except only for its own grossly negligent action, its own
grossly negligent failure to act or its own willful misconduct in complying with
this Section 9.08.

          (b) Application by Trustee of Trust Moneys. If the Company shall fail
to perform any of its covenants in this Indenture or under any Security

time to time, use, apply and advance any Trust Moneys held by it under this
Article IX or make advances to effect performance of any such covenant on behalf
of the Company as contemplated by this Indenture or the Security Documents;
provided that (i) the Trustee shall not be required to make any such advances
from its own funds and (ii) all moneys so used or advanced by the Trustee,
together (in the case of funds advanced by the Trustee) with interest at the
rate borne by the Notes shall be repaid by the Issuer upon demand and shall be
entitled to the benefit of the Liens of the Security Documents. For repayment of
all such advances the Trustee shall have the right to use and apply any Trust
Moneys at any time held by it under this Article IX but no such use of Trust
Moneys or advance shall relieve the Issuer from any Default or Event of Default.

     Supplements;

          (iv) to provide additional security for the Notes;

     Parties;

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

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

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

     subject to the Lien of this Indenture or the Security Documents, or to
     subject additional Property to the Lien of this Indenture or the Security
     Documents, or to release Property subject to the Lien of this Indenture or
     any Security Document in accordance with the provisions of this Indenture
     and the Security Documents.

          After an amendment, supplement or waiver under this Section 10.01
becomes effective, the Issuer make available to the Holders on a Qualified
Internet Site notice briefly describing the amendment, supplement or waiver. Any
failure of the Issuer to mail such notice, or any defect therein, shall not,
however, in any way impair or affect the validity of any such amendment,
supplement or waiver.

          SECTION 10.02. Consent of Holders.

          (a) Consent by Majority Holders. Without prior notice to the Holders,
the Credit Parties, when authorized by their respective Board of Directors (as
evidenced by a Board Resolution), and the Trustee may amend this Indenture, the
Notes, the Security Documents and the Intercreditor Agreement with the written
consent of the Holders of not less than a majority in aggregate principal amount
of the Notes then outstanding, and the Holders of at least a majority of the
principal amount of the Notes then outstanding by written notice to the Trustee
may waive future compliance by any Credit Party with any provision of this

the Security Documents. The consent of the Holders shall not be required for any
amendment, modification or supplement of this Indenture or any Security Document

                                    Indenture

<PAGE>

                                     -106-

solely (i) in order to effectuate the subordination of the Lien of the Security
Documents to any Lien securing a Working Capital Facility as contemplated by
Section 6.04 hereof or (ii) in connection with the release by the Trustee of any
Lien upon any Property of the Company or any Subsidiary that is the subject of a
sale or other disposition permitted hereunder, to the extent such release is
required pursuant to Section 6.05 hereof.

          (b) Consent by Each Holder. Notwithstanding the provisions of
paragraph (a) of this Section 10.02, without the consent of each Holder
affected, an amendment or waiver, including a waiver pursuant to Section 7.04
hereof, may not:

          (i) reduce the amount of Notes whose Holders must consent to an
     amendment;

          (ii) reduce the rate of or extend the time for payment of interest on
     any Note;

          (iii) reduce the principal of, premium on, or extend the Stated
     Maturity of any Note;

          (iv) change any place of payment where, or the currency in which, any
     Note or the interest thereon is payable;

          (v) impair the right of any Holder to receive payment of principal of,
     premium, if any, and interest on such Holder's Notes on or after the due
     dates therefor or to institute suit for the enforcement of any payment on
     or with respect to such Holder's Notes;

          (vi) make any change in the amendment provisions or in the waiver
     provisions of this Indenture (including the provisions of this Article X
     and Section 7.02 hereof) which require the consent of Holders of all or a
     specified percentage in principal amount of outstanding Notes;

          (vii) change the time at which any Note may be redeemed pursuant to
     Article III hereof; or

          (viii) amend the provisions of Section 3.08, 3.09, 4.10 or 4.15
     hereof.

          (c) Form of Consents. It shall not be necessary for the consent of the
Holders under this Section 10.02 to approve the particular form of any proposed
amendment, supplement or waiver, but it shall be sufficient if such consent
approves the substance thereof.

          (d) Notice of Amendment. After an amendment, supplement or waiver
under this Section 10.02 becomes effective, the Issuer shall mail to the Holders
affected thereby a notice briefly describing the amendment, supplement or
waiver. The Issuer shall mail copies of any such amendment, supplement or waiver
to Holders upon

                                    Indenture

<PAGE>

                                     -107-

request. Any failure of the Issuer to mail such notice, or any defect therein,
shall not, however, in any way impair or affect the validity of any such
amendment, supplement or waiver.

          SECTION 10.03. Revocation and Effect of Consent.

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

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

          SECTION 10.04. Notation on or Exchange of Notes.

          If an amendment, supplement or waiver changes the terms of a Note, the
Trustee may require the Holder to deliver it to the Trustee. The Trustee may
place an appropriate notation on the Note about the changed terms and return it
to the Holder and the Trustee may place an appropriate notation on any Note
thereafter authenticated. Alternatively, if the Issuer or the Trustee so
determines, the Issuer in exchange for a Note shall issue, and the Trustee shall
authenticate, a new Note that reflects the changed terms.

          SECTION 10.05. Trustee to Sign Amendments, Etc.

          The Trustee shall be entitled to receive, and shall be fully protected
in relying upon, an Officers' Certificate and Opinion of Counsel (at the cost
and expense of the Issuer) meeting the requirements of Sections 12.03 and 12.04
hereof and stating that the execution of any amendment, supplement or waiver
authorized pursuant to this Article X is authorized or permitted by this
Indenture and that all conditions precedent have been satisfied. The Trustee
may, but shall not be obligated to, execute any such amendment, supplement or
waiver that affects the Trustee's own rights, duties or immunities under this
Indenture or otherwise.

          SECTION 10.06. Conformity with Trust Indenture Act.

          Every amendment, supplement and waiver executed pursuant to this
Article X shall conform to the requirements of the TIA as then in effect.

          SECTION 10.07. Amendments to Security Documents.

          Except as otherwise provided in Sections 10.01 and 10.02 hereof, the
Credit Parties shall not amend, modify or supplement, or permit or consent to
any amendment, modification or supplement of, this Indenture, the Notes or the
Security Documents.

                            ARTICLE XI NOTE GUARANTEE

          SECTION 11.01. Note Guarantee.

          Subject to this Article XI, each of the Guarantors hereby, jointly and
severally, unconditionally guarantees to each Holder of a Note 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,
the Security Documents or the obligations of the Issuer hereunder or thereunder,
that: (a) the principal of, premium, if any, and interest on the Notes will be
promptly paid in full when due, whether at maturity, by acceleration, redemption
or otherwise, and interest on the overdue principal of, premium, if any, and
interest on the Notes, if any, if lawful, and all other obligations of the
Issuer to the Holders or the Trustee hereunder or thereunder will be promptly
paid in full or performed, all in accordance with the terms hereof and thereof;
and (b) in case of any extension of time of payment or renewal of any Notes or
any of such other obligations, that the same will be promptly paid in full when
due or performed in accordance with the terms of the extension or renewal,
whether at stated maturity, by acceleration or otherwise. Failing payment when
due of any amount so guaranteed or any performance so guaranteed for whatever
reason, the Guarantors shall be jointly and severally obligated to pay the same
immediately. Each Guarantor agrees that this is a guarantee of payment and not a
guarantee of collection.

          The obligations of the Guarantors under this Article XI are absolute
and unconditional, joint and several, irrespective of the value, genuineness,
validity, regularity or enforceability of the obligations of the Issuer under
this Indenture, the Notes or the Security Documents, or any other agreement or
instrument referred to herein or therein, or any substitution, release or
exchange of any other guarantee of or security for any of the Guaranteed
Obligations, and, to the fullest extent permitted by applicable law,
irrespective of any other circumstance whatsoever that might otherwise
constitute a legal or equitable discharge or defense of a surety or guarantor,
it being the intent of this Article XI that the obligations of the Guarantors
hereunder shall be absolute and unconditional, joint and several, under any and
all circumstances. Without limiting the generality of the foregoing, it is
agreed that the occurrence of any one or more of the

                                    Indenture

<PAGE>

                                     -109-

following shall not alter or impair the liability of the Guarantors hereunder,
which shall remain absolute and unconditional as described above:

          (i) at any time or from time to time, without notice to the
     Guarantors, the time for any performance of or compliance with any of the
     Guaranteed Obligations shall be extended, or such performance or compliance
     shall be waived;

          (ii) any of the acts mentioned in any of the provisions of this
     Indenture, the Notes or the Security Documents, or any other agreement or
     instrument referred to herein or therein shall be done or omitted;

          (iii) the maturity of any of the Guaranteed Obligations shall be
     accelerated, or any of the Guaranteed Obligations shall be modified,
     supplemented or amended in any respect, or any right under this Indenture,
     the Notes or the Security Documents, or any other agreement or instrument
     referred to herein or therein, shall be waived or any other guarantee of
     any of the Guaranteed Obligations or any security therefor shall be
     released or exchanged in whole or in part or otherwise dealt with; or

          (iv) any Lien granted to, or in favor of, the Trustee as security for
     any of the Guaranteed Obligations (including pursuant to any of the
     Security Documents) shall fail to be perfected.

The Guarantors hereby expressly waive diligence, presentment, demand of payment,
protest and all notices whatsoever, and any requirement that the Trustee or any
Holder exhaust any right, power or remedy or proceed against the Issuer under
this Indenture, the Notes or the Security Documents, or any other agreement or
instrument referred to herein or therein, or against any other Person (including
any other Guarantor hereunder) under any other guarantee of, or security for,
any of the Guaranteed Obligations.

          If any Holder or the Trustee is required by any court or otherwise to
return to the Issuer, the Guarantors or any custodian, trustee, liquidator or
other similar official acting in relation to either the Issuer or the
Guarantors, any amount paid by either to the Trustee or such Holder, this Note
Guarantee, to the extent theretofore discharged, shall be reinstated in full
force and effect.

          Each Guarantor agrees that it shall not be entitled to any right of
subrogation in relation to the Holders in respect of any obligations guaranteed
hereby until payment in full of all obligations guaranteed hereby. Each
Guarantor further agrees that, as between the Guarantors, on the one hand, and
the Holders and the Trustee, on the other hand, (x) the maturity of the
Guaranteed Obligations may be accelerated as provided in Article VII hereof for
the purposes of this Note Guarantee, notwithstanding any stay, injunction or
other prohibition preventing such acceleration in respect of the Guaranteed
Obligations and (y) in the event of any declaration of acceleration of such
obligations as provided in Article VII hereof, such obligations (whether or not
due and

                                    Indenture

<PAGE>

                                     -110-

payable) shall forthwith become due and payable by the Guarantors for the
purpose of this Note Guarantee.

          SECTION 11.02. Limitation on Guarantor Liability.

          Each Guarantor, and by its acceptance of Notes, each Holder, hereby
confirms that it is the intention of all such parties that the Note Guarantee of
such Guarantor not constitute a fraudulent transfer or conveyance for purposes
of any Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform
Fraudulent Transfer Act or any similar foreign, federal or state law to the
extent applicable to any Note Guarantee. To effectuate the foregoing intention,
the Trustee, the Holders and the Guarantors hereby irrevocably agree that the
obligations of such Guarantor under its Note Guarantee and this Article XI shall
be limited to the maximum amount as will, after giving effect to such maximum
amount and all other contingent and fixed liabilities of such Guarantor that are
relevant under such laws, and after giving effect to any collections from,
rights to receive contribution from, or payments made by or on behalf of, any
other Guarantor in respect of the obligations of such other Guarantor under this
Article XI, result in the obligations of such Guarantor under its Note Guarantee
not constituting a fraudulent transfer or conveyance. Without limiting the
generality of the foregoing, the obligations of each Guarantor identified in
Schedule 3 hereto shall be limited as set forth therein.

          SECTION 11.03. Rights of Contribution.

          The Guarantors hereby agree, as between themselves, that if any
Guarantor shall become an Excess Funding Guarantor (as defined below) by reason
of the payment by such Guarantor of any Guaranteed Obligations, each other
Guarantor shall, on demand of such Excess Funding Guarantor (but subject to the
next sentence), pay to such Excess Funding Guarantor an amount equal to such
Guarantor's Pro Rata Share (as defined below and determined, for this purpose,
without reference to the Property, debts and liabilities of such Excess Funding
Guarantor) of the Excess Payment (as defined below) in respect of such
Guaranteed Obligations. The payment obligation of a Guarantor to any Excess
Funding Guarantor under this Section 11.03 shall be subordinate and subject in
right of payment to the prior payment in full of the obligations of such
Guarantor under the other provisions of this Article XI and such Excess Funding
Guarantor shall not exercise any right or remedy with respect to such excess
until payment and satisfaction in full of all of such obligations.

          For purposes of this Section 11.03, (i) "Excess Funding Guarantor"
means, in respect of any Guaranteed Obligations, a Guarantor that has paid an
amount in excess of its Pro Rata Share of such Guaranteed Obligations, (ii)
"Excess Payment" means, in respect of any Guaranteed Obligations, the amount
paid by an Excess Funding Guarantor in excess of its Pro Rata Share of such
Guaranteed Obligations and (iii) "Pro Rata Share" means, for any Guarantor, the
ratio (expressed as a percentage) of (x) the amount by which the aggregate
present fair saleable value of all Property of such Guarantor (excluding any
shares of stock of any other Guarantor) exceeds the amount of all the debts and
liabilities of such Guarantor (including contingent, subordinated,

                                    Indenture

<PAGE>

                                     -111-

unmatured and unliquidated liabilities, but excluding the obligations of such
Guarantor hereunder and any obligations of any other Guarantor that have been
Guaranteed by such Guarantor) to (y) the amount by which the aggregate fair
saleable value of all Property of all of the Guarantors exceeds the amount of
all the debts and liabilities (including contingent, subordinated, unmatured and
unliquidated liabilities, but excluding the obligations of the Issuer and the
Guarantors hereunder and under the Security Documents) of all of the Guarantors,
determined (A) with respect to any Guarantor that is a party hereto on the date
hereof, as of the Issue Date and (B) with respect to any other Guarantor, as of
the date such Guarantor becomes a Guarantor hereunder.

          SECTION 11.04. Parallel Debt Structure - Relevant Jurisdictions.

          (a) Creation of Parallel Obligations. For purposes of (x) creating a
Lien in the Collateral in or subject to the laws of any jurisdiction (each being
herein called a "Relevant Jurisdiction"), such as Austria, France, Hungary,
Luxembourg, The Netherlands, Spain, Sweden or Switzerland, but excluding Belgium
(as to which the provisions of Section 11.05 hereof shall be applicable) that
only permits Liens of a certain type to be granted to the Trustee to secure
obligations directly held by the Trustee and (y) ensuring the continued validity
of any such Lien, the Trustee and the Credit Parties, and each Holder by
acceptance of the Notes, agrees that notwithstanding anything to the contrary
contained in this Indenture or any Note or Security Document:

          (i) for purposes of this Section 11.04, "Principal Obligations" means
     in respect of each Relevant Jurisdiction and in relation to a Credit Party
     having assets in such Relevant Jurisdiction, any sums owing by it to the
     Holders under this Indenture, the Notes or any Security Document;

          (ii) such Credit Party shall be obligated to the Trustee an amount
     equal to, and in the same currency of, its Principal Obligations as and
     when the same become due and payable under this Indenture, the Notes or the
     relevant Security Document (the "Parallel Obligations"); provided that the
     total amount of the Parallel Obligations of such Credit Party shall never
     exceed the total amount of the Principal Obligations of such Credit Party;

          (iii) the rights of the Holders to receive payment of the Principal
     Obligations are several from the rights of the Trustee to receive payment
     of the Parallel Obligations;

          (iv) the Trustee shall have an independent right, in its own name and
     stead, to demand payment of the Parallel Obligations by the Credit Parties
     upon the occurrence and during the continuance of an unremedied and
     unwaived Event of Default (except that, in the case of an Event of Default
     specified in paragraph (i) or (j) of Section 7.01 hereof, the Parallel
     Obligations shall be due and payable immediately without any such demand or
     other action or notice);

                                    Indenture

<PAGE>

                                     -112-

          (v) the payment by such Credit Party of its Parallel Obligations to
     the Trustee in accordance with this Section 11.04 (whether through direct
     payment by such Credit Party or enforcement of its Note Guarantee or any
     Lien held by the Trustee securing the Parallel Obligations) shall discharge
     the corresponding Principal Obligations of such Credit Party, and,
     similarly, the payment by such Credit Party of its Principal Obligations
     (whether through direct payment by such Credit Party or enforcement of its
     Note Guarantee or any Lien held by the Trustee securing the Principal
     Obligations) shall discharge its corresponding Parallel Obligations owed to
     the Trustee under this Section 11.04; and

          (vi) nothing in this Section 11.04 shall in any way limit the
     Trustee's right to act in the protection or preservation of, the rights
     under, or to enforce any, Security Document as contemplated by this
     Indenture or any Security Document.

          (b) No Limitation of Principal Obligations. Nothing in this Section
11.04 shall in any way negate or affect the obligations of any Credit Party to
the Holders under this Indenture, the Notes and the Security Documents.

          (c) Role and Undertaking of Trustee. For purposes of this Section
11.04, the Trustee acts in its own name and stead and not as agent or trustee of
any Holder, and the security granted under the Security Documents to the Trustee
to secure the Parallel Obligations is granted to the Trustee in its capacity as
a direct creditor in respect of the Parallel Obligations, and not as a trustee
or agent for the Holders. The Trustee undertakes to pay to the Holders an amount
equal to any amount collected or received by it which it has applied in
reduction of the Parallel Obligations as if the corresponding Principal
Obligations had not been discharged pursuant to Section 11.04(a)(v) hereof.

          SECTION 11.05. Parallel Debt Structure - Belgium.

          (a) Creation of Parallel Obligations. For purposes of (x) creating a
floating charge by each Guarantor organized under the law of Belgium (herein, a
"Belgian Guarantor"), and a mortgage by GC Pan European Global Crossing Belgie
BVBA in or subject to the laws of Belgium and (y) ensuring the continued
validity of any such Lien, the Trustee and the Belgian Guarantors, and each
Holder by acceptance of the Notes, agrees that notwithstanding anything to the
contrary contained in this Indenture or any Note or Security Document:

          (i) for purposes of this Section 11.05, "Principal Obligations" means
     in respect of Belgium and in relation to a Belgian Guarantor, any sums
     owing by it to the Holders under this Indenture, the Notes or any Security
     Document;

          (ii) the respective Belgian Guarantor shall pay to the Trustee, with
     respect to the mortgage granted by GC Pan European Crossing Belgie BVBA,
     and to a bank that qualifies as an "EU Credit Institution" under Belgium
     law and that is designated by the Trustee (the "Belgian Floating Charge
     Lienholder"), with respect to the floating charge granted by such Belgian
     Guarantor over its

     commercial business, an amount equal to, and in the same currency of, its
     Principal Obligations as and when the same become due and payable under
     this Indenture, the Notes and the Security Documents (the "Parallel
     Obligations"); provided that the total amount of the Parallel Obligations
     of such Belgium Guarantor shall never exceed the total amount of the
     Principal Obligations of such Belgium Guarantor;

          (iii) the rights of the Holders to receive payment of the Principal
     Obligations are several from the rights of the Trustee and the Belgian
     Floating Charge Lienholder to receive payment of the Parallel Obligations;

          (iv) each of the Trustee and the Belgian Floating Charge Lienholder
     shall have an independent right, in its own name and stead, to demand
     payment of the Parallel Obligations by the respective Belgian Guarantor
     upon the occurrence and during the continuance of an unremedied and
     unwaived Event of Default (except that, in the case of an Event of Default
     specified in paragraph (i) or (j) of Section 7.01 hereof, the Parallel
     Obligations shall be due and payable immediately without any such demand or
     other action or notice);

          (v) the payment by a Belgian Guarantor of its Parallel Obligations to
     the Trustee or, as the case may be, the Belgian Floating Charge Lienholder,
     in accordance with this Section 11.05 (whether through direct payment by
     such Belgian Guarantor or enforcement of its Note Guarantee or any Lien
     held by the Trustee or the Belgian Floating Charge Lienholder securing the
     Parallel Obligations) shall discharge the corresponding Principal
     Obligations of such Belgian Guarantor, and, similarly, the payment by a
     such Belgian Guarantor of the Principal Obligations (whether through direct
     payment by such Belgian Guarantor or enforcement of its Note Guarantee or
     any Lien held by the Trustee securing the Principal Obligations) shall
     discharge the corresponding Parallel Obligations owed to the Trustee or, as
     the case may be, the Belgian Floating Charge Lienholder, under this Section
     11.05; and

          (vi) nothing in this Section 11.05 shall in any way limit the
     Trustee's or the Belgian Floating Charge Lienholder's, right to act in the
     protection or preservation of, the rights under, or to enforce any,
     Security Document as contemplated by this Indenture or any Security
     Document.

          (b) No Limitation of Principal Obligations. Nothing in this Section
11.05 shall in any way negate or affect the obligations of any Belgian Guarantor
to the Holders under this Indenture, the Notes and the Security Documents.

          (c) Role and Undertaking of Trustee and Belgian Floating Charge
Lienholder. For purposes of this Section 11.05, each of the Trustee and the
Belgian Floating Charge Lienholder acts in its own name and stead and not as
agent or trustee of any Holder, and the security granted under the Security
Documents to the Trustee or, as the case may be, the Belgian Floating Charge
Lienholder to secure the Parallel

Obligations is granted to the Trustee or, as the case may be, the Belgian
Floating Charge Lienholder in its capacity as a direct creditor in respect of
the Parallel Obligations, and not as a trustee or agent for the Holders. The
Trustee undertakes (and the Belgian Floating Charge Lienholder, pursuant to the
floating charge referred to in Section 11.05(a)(ii) hereof will undertake) to
pay to the Holders an amount equal to any amount collected or received by it
which it has applied in reduction of the Parallel Obligations as if the
corresponding Principal Obligations had not been discharged pursuant to Section
11.05(a)(v) hereof.

          SECTION 11.06. Guarantee Limitations.

          Notwithstanding anything in this Indenture to the contrary, (a) the
obligations of any of GCUK or any of its Subsidiaries that are Guarantors shall
not in the aggregate exceed $225,000,000 under any Note Guarantee (and,
accordingly, the maximum aggregate amount that GCUK and its Subsidiaries are
required to pay pursuant to this Article XI shall not exceed $225,000,000) and
(b) the obligations of any of Global Marine or any of its Subsidiaries that are
Guarantors shall not in the aggregate exceed $44,200,000 under any Note
Guarantee (and, accordingly, the maximum aggregate amount that Global Marine and
its Subsidiaries are required to pay pursuant to this Article XI shall not
exceed $44,200,000).

                            ARTICLE XII MISCELLANEOUS

          SECTION 12.01. Trust Indenture Act of 1939.

          This Indenture shall be subject to the provisions of the TIA that are
required to be a part of this Indenture and shall, to the extent applicable,
incorporate and be governed by such provisions.

          SECTION 12.02. Notices.

          (a) Addresses for Notices. Any notice or communication shall be
sufficiently given if in writing and delivered in person, telecopied or mailed
by first class mail addressed as follows:

     if to the Issuer or any Guarantor:

          Office of the General Counsel
          Global Crossing Limited
          200 Park Avenue, M Suite 300
          Florham Park, NJ 07932
          Facsimile: 973-360-0538

                                    Indenture

<PAGE>

                                     -115-

     if to the Trustee:

          Wells Fargo Bank Minnesota, N.A.
          Corporate Trust
          Sixth Street and Marquette Avenue
          MAC N 9303-120
          Minneapolis, MN 55479
          Attention: Corporate Trust
          Facsimile: 612-667-9825

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

          (b) Mailing of Notices to Holders. Any notice or communication mailed
to a Holder shall be mailed to him/her at his/her address as it appears on the
Note Register by first class mail and shall be sufficiently given to him/her if
so mailed within the time prescribed. Copies of any such communication or notice
to a Holder shall also be mailed to the Trustee and each Agent at the same time.
In case by reason of the suspension of first class mail service or by reason of
any other cause it shall be impracticable to give such notice by first class
mail, then such notification by nationally recognized national or international
courier shall constitute a sufficient notification for every purpose hereunder
in lieu of notification by first class mail.

          (c) Effectiveness of Notices. Failure to mail a notice or
communication to a Holder or any defect in it shall not affect its sufficiency
with respect to other Holders. All notices shall be effective upon receipt by
the party to which such notice is directed. If any such notice shall be
delivered on a non-Business Day, such notice shall be deemed effective on the
next Business Day.

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

          SECTION 12.03. Certificate and Opinion as to Conditions Precedent.

          Upon any request or application by any Credit Party to the Trustee to
take any action under this Indenture, such Credit Party shall furnish to the
Trustee:

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

                                    Indenture

<PAGE>

                                     -116-

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

          The Credit Parties shall otherwise comply with Section 314(c) of the
TIA.

          SECTION 12.04. Statements Required in Certificate or Opinion.

          Each certificate or opinion with respect to compliance with a
condition or covenant provided for in this Indenture shall include:

          (a) a statement that the person making such certificate or opinion has
     read such covenant or condition;

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

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

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

          SECTION 12.05. Rules by Trustee, Paying Agent or Registrar.

          The Trustee may make reasonable rules for action by or at a meeting of
Holders. The Paying Agent and the Registrars may each make reasonable rules for
its functions.

          SECTION 12.06. Payment Date Other Than a Business Day.

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

                                     -117-

          SECTION 12.07. Governing Law.

          THE LAW OF THE STATE OF NEW YORK SHALL GOVERN THIS INDENTURE, THE
NOTES AND, TO THE EXTENT PROVIDED THEREIN, THE SECURITY DOCUMENTS, IN EACH CASE
WITHOUT GIVING EFFECT TO APPLICABLE PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT
THAT THE APPLICATION OF THE LAW OF ANOTHER JURISDICTION WOULD BE REQUIRED
THEREBY.

          SECTION 12.08. No Adverse Interpretation of Other Agreements; Use of
English Language.

          This Indenture may not be used to interpret another indenture, loan or
debt agreement of the Company or any Subsidiary of the Company. Any such
indenture, loan or debt agreement may not be used to interpret this Indenture.

          This Indenture has been executed in the English language. All
certificates, reports, notices and other documents and communications given or
delivered pursuant to this Agreement (including any modifications or supplements
hereto) shall be in the English language, or accompanied by a certified English
translation thereof. In connection with the registration of Security Documents
outside of the United States of America, it may be necessary that this Indenture
be translated into other languages; provided that it is understood and agreed
that the sole official version of this Indenture is the English language version
executed by the parties hereto.

          SECTION 12.09. No Recourse Against Others.

          Except for the Note Guarantee provided for in Article XI hereof, no
director, officer, employee, incorporator, equity holder or shareholder of the
Issuer shall have any liability for any obligations of the Issuer under the
Notes or this Indenture or any Security Documents or for any claim based on, in
respect of, or by reason of, such obligations or their creation. No director,
officer, employee, incorporator, equity holder or stockholder of any of the
Guarantors shall have any liability for any obligations of the Guarantors under
the Note Guarantees, this Indenture or the Security Documents or for any claim
based on, in respect of, or by reason of, such obligations or their creation.
Each Holder, by accepting a Note, waives and releases all such liabilities. Such
waiver and release are part of the consideration for the issuance of the Notes.
Such waiver may not be effective to waive liabilities under federal securities
laws and it is the current view of the Commission that such a waiver is against
public policy.

          SECTION 12.10. Successors.

          All agreements of the Issuer and the Guarantors in this Indenture and
the Notes shall bind each of its successors and its assigns by way of merger,
amalgamation or otherwise. All agreements of the Trustee in this Indenture shall
bind its successor. All agreements made on behalf of the Holders shall bind each
successor Holder and its assigns.

                                     -118-

          SECTION 12.11. Multiple Originals.

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

          SECTION 12.12. Severability.

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

          SECTION 12.13. Qualification of Indenture.

          The Issuer shall qualify this Indenture under the TIA and shall pay
all reasonable costs and expenses (including attorneys' fees for the Issuer, the
Trustee and the Holders) incurred in connection therewith, including, but not
limited to, costs and expenses of qualification of this Indenture and printing
this Indenture. The Trustee shall be entitled to receive from the Issuer any
such Officers' Certificates, Opinions of Counsel or other documentation as it
may reasonably request in connection with any such qualification of this
Indenture under the TIA.

          SECTION 12.14. Table of Contents, Headings, Etc.

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

          SECTION 12.15. Consent to Jurisdiction.

          Each Credit Party hereby irrevocably submits to the non-exclusive
jurisdiction of any New York State or Federal court sitting in New York City and
any appellate court from any thereof for the purposes of (and solely for the
purposes of) any suit, action or other proceeding arising out of or relating to
this Indenture or any of the transactions contemplated hereby, and each Credit
Party hereby irrevocably agrees that all claims in respect of such action or
proceeding may be heard and determined in such New York State court or in such
Federal court. Each Credit Party hereby (to the fullest extent it may
effectively do so) irrevocably waives and agrees not to assert, by way of
motion, as a defense, or otherwise in any such suit, action or proceeding, any
claim that it is not personally subject to the jurisdiction of the above-named
courts for any reason whatsoever, that such suit, action or proceeding is
brought in an inconvenient forum or that the venue of such suit, action or
proceeding is improper, or that this Indenture or the subject matter hereof may
not be enforced in such courts.

          Each Credit Party hereby irrevocably appoints Corporation Services
Company, presently located at 1177 Avenue of the Americas, New York, New York
10036 as its agent (the "Authorized Agent") to receive on behalf of such Credit
Party and its Property service of copies of the summons and complaint and any
other process which

                                    Indenture

<PAGE>

                                     -119-

may be served in any such suit, action or proceeding and in any suit, action or
proceeding arising out of or relating to this Indenture to which such Credit
Party is a party. Such service may be made by mailing or delivering a copy of
such process to the Authorized Agent, and each Credit Party hereby irrevocably
authorize and direct the Authorized Agent to accept such service on its behalf.
As an alternative method of service, each Credit Party also irrevocably consents
to the service of any and all process in any such suit, action or proceeding by
the mailing of copies of such process to such Credit Party at its address
specified in Section 12.02 hereof. Each Credit Party agrees to take any and all
action, including the filing of any and all documents and instruments, that may
be necessary to continue such appointment in full force and effect as aforesaid.

          Service of process upon the Authorized Agent and written notice of
such service to the applicable Credit Party in accordance with Section 12.02 of
this Indenture shall be deemed, in every respect, effective service of process
upon such Credit Party. Each Credit Party agrees that a final judgment in any
such suit, action or proceeding shall be conclusive and may be enforced in other
jurisdictions by suit on the judgment or in any other manner provided by law.
Nothing in this Section 12.15 shall affect the right of the Trustee to serve
legal process in any other manner permitted by law or affect the right of the
Trustee to bring any action or proceeding against any Credit Party or its
Property in the courts of any other jurisdictions.

          SECTION 12.16. Waiver of Jury Trial.

          EACH OF THE CREDIT PARTIES AND THE TRUSTEE HEREBY IRREVOCABLY WAIVES,
TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY
JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS INDENTURE OR THE
TRANSACTIONS CONTEMPLATED HEREBY.

          SECTION 12.17. Judgment Currency.

          The Credit Parties shall jointly and severally indemnify each Holder
against any loss incurred by such Holder as a result of any judgment or order
being given or made for any amount due under this Indenture, the Notes or the
Note Guarantees and such judgment or order being expressed and paid in a
currency (the "Judgment Currency") other than U.S. Dollars and as a result of
any variation as between the rate of exchange at which the U.S. Dollar amount is
converted into the Judgment Currency for the purpose of such judgment or order
and the spot rate of exchange in The City of New York at which such Holder on
the date of payment of such judgment or order is able to purchase U.S. Dollars
with the amount of the Judgment Currency actually received by such Holder. The
foregoing indemnity shall constitute a separate and independent obligation of
the Credit Parties and shall continue in full force and effect notwithstanding
any such judgment or order as aforesaid.

          The Credit Parties shall jointly and severally indemnify the Trustee
and its and its officers, directors, employees, representatives and agents and
the Belgian Floating Charge Lienholder (collectively, the "Indemnified Parties")
against any loss incurred by

                                    Indenture

<PAGE>

                                     -120-

any such Indemnified Party as a result of any judgment or order being given or
made for any amount due under this Indenture, the Notes or the Note Guarantees
and such judgment or order being expressed and paid in a Judgment Currency other
than U.S. Dollars and as a result of any variation as between the rate of
exchange at which the U.S. Dollar amount is converted into the Judgment Currency
for the purpose of such judgment or order and the spot rate of exchange in The
City of New York at which such Indemnified Party on the date of payment of such
judgment or order is able to purchase U.S. Dollars with the amount of the
Judgment Currency actually received by such Indemnified Party. The foregoing
indemnity shall constitute a separate and independent obligation of the Credit
Parties and shall continue in full force and effect notwithstanding any such
judgment or order as aforesaid.

          For purposes of this Section 12.17, the term "spot rate of exchange"
shall include any premiums and costs of exchange payable in connection with the
purchase of, or conversion into, U.S. Dollars.

          SECTION 12.18. Immunity.

          To the extent that any Credit Party may be or become entitled, in any
jurisdiction in which judicial proceedings may at any time be commenced with
respect to this Indenture, the Notes, the Note Guarantees or any of the Security
Documents, to claim for itself or its properties or revenues any immunity from
suit, court jurisdiction, attachment prior to judgment, attachment in aid of
execution of a judgment, execution of a judgment or from any other legal process
or remedy relating to its obligations under this Indenture, the Notes, the Note
Guarantees or any of the Security Documents, and to the extent that in any such
jurisdiction there may be attributed such an immunity (whether or not claimed),
such Credit Party hereby irrevocably agrees not to claim and hereby irrevocably
waives such immunity to the fullest extent permitted by the laws of such
jurisdiction and consents generally for the purposes of the State Immunity Act
of 1978 of the United Kingdom to the giving of any relief or the issue of any
process.

          SECTION 12.19. Status of Indenture under Japanese Law.

          This Indenture shall be referred to as "_________________" (Saimu
Bensai Keiyaku) under the laws of Japan and
"_____15___11____12____________________________" (Saimu Bensai Keiyaku dated
December 9, 2003), which shall appear in the registration of the Japanese
mortgage on the motor vessel "WAVE MERCURY", shall mean this Indenture.

                   [Provisions Relating to Certain Guarantors]

Belgium

          The obligations of any Guarantor organized under the laws of Belgium
(herein, a "Belgian Guarantor") under the Indenture and any Security Documents
to which it is a party shall be limited to the extent that payment of such
obligations would cause such Belgian Guarantor's Net Assets to be reduced below
one-half of the amount of its registered share capital in accordance with
Article 332 of the Belgian Code of Companies (as amended from time to time), or
where such Belgian Guarantor's Net Assets already are below one-half of the
amount of its registered share capital, cause such Belgian Guarantor's Net
Assets to be further reduced (and in that connection, such Belgian Guarantor
agrees not to increase its registered share capital if the effect thereof would
be to reduce the amount of the limitation hereunder).

          For purposes hereof, "Net Assets" shall have the meaning given to it
by Article 320 of the Belgian Code of Companies (as amended from time to time).

France

          The obligations of any Guarantor organized under the laws of France
(herein, a "French Guarantor") under the Indenture (and specifically Article XI
thereof, and under any Security Documents to which it is a party, shall be
limited to an aggregate amount equal to the 85% of the higher of (i) the Net
Worth of such French Guarantor at the Issue Date and (ii) the Net Worth of such
French Guarantor at the time of the enforcement of such obligations.

          For purposes hereof, "Net Worth" means, in respect of any French
Guarantor, such French Guarantor's net worth ("capitaux propres") (including the
registered share capital, share premium, legal and statutory reserves, other
reserves, profits or losses carried forward, investment subsidies and regulated
provisions) as shown in the most recent financial statements (comptes annuels)
of such French Guarantor as certified by the statutory auditors and available at
the Issue Date or the date of its enforcement hereunder as the case may be.

Germany

          The obligations of any Guarantor organized under the laws of Germany
(herein, a "German Guarantor") under the Indenture and any Security Documents to
which it is a party shall be limited to the extent that enforcement of such
obligations would cause such German Guarantor's Net Assets (Reinvermogen) to be
reduced below the amount of its registered share capital protected by sections
30 and 31 of the German

                                    Indenture

<PAGE>

                                      -2-

Limited Liability Companies Act (GmbHG), or where such German Guarantor's Net
Assets already are below the amount of its registered share capital, cause such
amount to be further reduced.

          For the purpose of this Schedule 3, "Net Assets" shall be defined as
the total assets (Section 266(2) German Commercial Code) of the relevant German
Guarantor less (i) its accruals (Section 266(3)(B) German Commercial Code), (ii)
its liabilities (Section 266(3)(C) German Commercial Code) and (iii) its
deferred income (Section 266(3)(D) German Commercial Code); provided that for
the purposes of calculating the Net Assets of the relevant German Guarantor the
following balance sheet items shall be adjusted as follows:

          (A) the amount of any increase of the registered share capital out of
     retained earnings (Kapitalerhohung aus Gesellschaftsmitteln) after the
     Issue Date shall be deducted from the registered share capital of the
     relevant German Guarantor; and

          (B) loans and other contractual liabilities incurred in violation of
     the provisions of the Indenture or any security document, including any of
     the German Security Documents shall be disregarded.

          Furthermore, if and to the extent legally permissible and commercially
justifiable in respect of the relevant German Guarantor`s business, the relevant
German Guarantor shall, in the situation where

          (i) it does not have sufficient assets to maintain its capital; and

          (ii) its obligations under the Indenture and any Security Documents to
     which it is a party would therefore be limited under this Schedule 3 in
     whole or in part,

realize any and all of its assets that are shown in the balance sheet with a
book value (Buchwert) which is lower than the market value of such assets, and
are not essentially necessary for the German Guarantors' business
(betriebsnotwendig).

          If and to the extent legally permissible, the limitations provided for
in this Schedule 3 shall cease to apply if the relevant German Guarantor and the
shareholder(s) of the German Guarantor enter into a domination agreement
(Beherrschungsvertrag) and such domination agreement is registered in the
commercial register (Handelsregister) unless such shareholder(s) are unable to
fulfill their obligations under such domination agreement due to circumstances
that would allow the initiation of insolvency proceedings against it.

                                      -3-

          The obligations of any Guarantor organized under the laws of Italy
(herein, an "Italian Guarantor") under the Indenture and any Security Documents
to which it is a party shall be limited to such amount as would not cause such
Italian Guarantor's net assets (e.g. net equity as per the Italian Guarantor's
Italian financial statements) to be reduced below the amount of its registered
share capital as defined by the Italian Civil Code, or where such Italian
Guarantor's net assets already are below the amount of its registered share
capital cause such amount to be further reduced (and in that connection, such
Italian Guarantor, and each Credit Party that is a shareholder of such Italian
Guarantor, agrees not to increase its registered share capital (capitale
sociale), except to the extent required under mandatory provisions of Italian
law).

Luxembourg

          The obligations of any Guarantor organized under the laws of
Luxembourg (herein, a "Luxembourg Guarantor") under the Indenture and any
Security Documents to which it is a party shall be limited to an amount equal to
95% of the Luxembourg Guarantor's equity (including the share capital, share

forward, investment subsidies and regulated provisions) as shown on the latest
financial statements available at the date of the relevant payment and approved
by such Luxembourg Guarantor's shareholders and certified by the statutory or
the independent auditor, as the case may be.

Norway

          Without limiting the generality of the foregoing, the obligations of
each Guarantor incorporated in Norway shall not cover any Indebtedness which, if
covered, would cause an infringement of sections 8-7 or 8-10 cfr. Section 1-4 of
the Norwegian Companies Act.

Sweden

          The obligations of any Guarantor organized under the laws of the
Kingdom of Sweden (herein, a "Swedish Guarantor") under the Indenture, and under
any Security Documents to which it is a party, shall be limited to such amount
as would not cause such Swedish Guarantor's Net Assets to be reduced below an
amount equal to its registered share capital, or where such Swedish Guarantor's
Net Assets already are below the amount of its registered share capital, cause
such Swedish Guarantor's Net Assets to be further reduced (and in that
connection, such Swedish Guarantor, and each Credit Party that is a shareholder
of such Swedish Guarantor, does not agree to increase its registered share
capital).

          For purposes hereof, "Net Assets" means, in respect of any Swedish
Guarantor, such Swedish Guarantor's equity (including the registered share
capital, share premium, legal and statutory reserves, other reserves, profits or
losses carried forward, investment subsidies and regulated provisions) as shown
on the latest financial statements

Switzerland

          The obligations of any Guarantor organized under the laws of
Switzerland (herein, a "Swiss Guarantor") under the Indenture and any Documents
to which it is a party shall be limited to the maximum amount of profits
available for distribution by such Swiss Guarantor as dividends at the time or
times the obligations of such Swiss Guarantor fall due (being the balance sheet

with the Articles 804 et seq. of the Swiss Code of Obligations), as evidenced by
an interim balance sheet of the respective Swiss Guarantor.

100% of the principal amount thereof, plus accrued and unpaid interest thereon,

Article III of the Indenture, it being understood that, to the extent any such

the Excess Proceeds remaining after such payment shall be applied to the making
of an Asset Sale Offer. To the extent that any Excess Proceeds remain after
consummation of an Asset Sale Offer, the Company may use such Excess Proceeds
for any purpose not otherwise prohibited by the Indenture. If the aggregate

of Excess Proceeds, the Trustee shall select the Notes to be purchased on a pro

Proceeds shall be reset at zero for purposes of the first sentence of this
paragraph.

is continuing, unremedied and unwaived, the Notes may be declared due and
payable in the manner and with the effect provided in the Indenture.

          11. Amendment, Modification and Waiver.

with certain exceptions as therein provided, the Holders of not less than a

Default shall cease to exist, and any Event of Default arising therefrom shall
be deemed to have been cured for every purpose of the Indenture and this Note,
but no waiver shall extend to any subsequent or other Default or impair any
right consequent thereon.

a party. Such service may be made by mailing or delivering a copy of such
process to the Additional Guarantor in care of the Process Agent at the Process
Agent's above address, and the Additional Guarantor hereby irrevocably authorize
and direct the Process Agent to accept such service on its behalf. As an
alternative method of service, the Additional Guarantor also irrevocably
consents to the service of any and all process in any such suit, action or
proceeding by the mailing of copies of such process to the Additional Guarantor
at its address specified in Section 12.02 of the Indenture. The Additional
Guarantor agrees that a final judgment in any such suit, action or proceeding
shall be conclusive and may be enforced in other jurisdictions by suit on the
judgment or in any other manner provided by law. Nothing herein shall affect the
right of the Trustee to serve legal process in any other manner permitted by law
or affect the right of the Trustee to bring any action or proceeding against the
Additional Guarantor or its Property in the courts of any other jurisdictions.

WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO
TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS

          The Trustee, on behalf of itself and the Noteholders, hereby agrees
that, regardless of the relative times of attachment or perfection thereof or
the order of filing of financing statements, mortgages or other documents or any
provision of the Uniform Commercial Code or any other applicable law to the

<PAGE>

                                       -8-

shall in all respects be junior and subordinate to the Liens granted or to be
granted to the Agent as security for the Working Capital Facility Secured
Obligations, in each case to the extent that such Liens in favor of the Agent
are valid, perfected and enforceable under the Uniform Commercial Code and all
other applicable law. The Trustee further agrees, on behalf of itself and the
Noteholders, that it shall not (and hereby waives any right to) take any action
to contest or challenge the validity, priority, enforceability or perfection of
the Liens of the Agent on the Shared Collateral.

          The Agent, on behalf of itself and the Working Capital Facility
Lenders, hereby confirms that, except for the Shared Collateral, none of the
assets of the Credit Parties or any of their Subsidiaries constitutes collateral
security for any of the Working Capital Facility Secured Obligations, and that
none of the Specified Subsidiaries is or shall be or become obligated, directly
or indirectly, in respect of any of the Working Capital Facility Secured
Obligations.

          Except as expressly set forth in this Agreement, each of the Trustee
and the Agent shall have any and all rights it may have as a creditor under
applicable bankruptcy or insolvency law, including the rights to exercise all
rights and remedies in foreclosure or otherwise with respect to any of the
Shared Collateral, provided that any such exercise by the Trustee, and any sale
of the Shared Collateral by the Trustee, shall be subject to the Liens of the
Agent on the Shared Collateral, and to the provisions of this Agreement,
including paragraph (c) or Article III hereof.

          In exercising rights and remedies with respect to the Shared
Collateral, the Agent and the Working Capital Facility Lenders may enforce the
provisions of, and exercise remedies under, the Working Capital Facility
Agreement and Working Capital Facility Security Documents, and the Trustee may
enforce the provisions of and exercise remedies under the Indenture and the
Indenture Security Documents, in each case in such order and in such manner as
the respective party enforcing such rights or exercising such remedies may
determine in its sole discretion. In the event of any sale, transfer, swap or
other disposition of any Shared Collateral constituting Equity Interests in any
Credit Party (other than the Issuer) upon the exercise of any remedies by the
Agent under the Working Capital Facility Security Documents, the Trustee agrees,
upon written request of the Agent (which request shall include a certification
to the effect that the conditions set forth in this sentence shall have been
satisfied), to release such Credit Party and any Subsidiaries of such Credit
Party from their respective obligations under the Indenture, the Note Guarantee
and the Indenture Security Documents so long as (i) such sale, transfer, swap or
other disposition is to a party other than an Affiliate of the Agent or any
Working Capital Facility Lender and (ii) the Agent and the Working Capital
Facility Lenders are concurrently releasing such Credit Party and its
Subsidiaries from their respective obligations under and in respect of the
Working Capital Facility Agreement and the Working Capital Facility Security
Documents.

                                   ARTICLE III

                               Further Assurances

          The Trustee and the Agent each agree with the other that, to the
extent it shall be necessary in any jurisdiction with respect to any Shared
Collateral to execute and deliver any additional documents, or take any
additional action, to either (i) implement the subordination of the Liens of the
Trustee on such Shared Collateral to the Liens of the Agent on such Shared
Collateral, or (ii) evidence further that the Agent has no claim against any of
the Property of the Specified Subsidiaries (other than Shared Continuing
Collateral), then each of the Trustee and Agent agree, upon request of the
other, to so execute and deliver such documents and take such additional action,
provided that the Trustee shall not be required to execute and deliver any such
documents or take any such action unless the request of the Agent shall be
accompanied by an Opinion of Counsel to the effect that such documents are in
fact required to be executed, or such action is in fact required to be taken, to
implement such subordination.

          Without limiting the generality of the foregoing, it is acknowledged
and agreed that, if requested by the Agent as provided above:

          (a) with respect to any Cash Collateral at any time held by the
     Trustee, the Trustee shall transfer (together with any necessary
     endorsements) any such Cash Collateral, including any thereof held in the
     Asset Sale Proceeds Account established under the Indenture, to an account
     established by the Agent at a bank or trust company in New York City (the
     "Cash Collateral Intermediary") unaffiliated with either the Trustee or the
     Agent and not constituting a Noteholder or Working Capital Facility Lender
     pursuant to a control or similar agreement to be entered into between the
     Cash Collateral Intermediary and the Trustee and Agent, which agreement
     shall provide that each of the Trustee and the Agent shall have "control"
     (as such term is defined in the Uniform Commercial Code) over such account
     and all Cash Collateral therein, and confirming that the Lien and security
     interest of the Trustee in such account and Cash Collateral shall be junior
     and subordinate to the Lien and security interest of the Agent in such
     account and Cash Collateral (and the Agent agrees that it shall not permit
     the balance held in such account to be invested at any time other than in
     Qualified Cash Equivalents), provided that any Cash Collateral held in such
     account may be released to the Company or any of its Subsidiaries (and the
     respective agreement with the Cash Collateral Intermediary shall so
     provide) only (i) upon the joint authorization of the Trustee and the Agent
     (which the Trustee has separately agreed to do upon satisfaction of the
     conditions in Article IX of the Indenture) to the Cash Collateral
     Intermediary or (ii) for application by the Agent to the payment of the
     Working Capital Facility Secured Obligations, so long as the Agent shall
     first have certified to the Trustee and the Cash Collateral Intermediary
     that a default in payment of Working Capital Facility Obligations has
     occurred and is continuing, unremedied and unwaived, and that the proceeds
     of such Cash Collateral are to be immediately applied to the payment of
     such defaulted Working Capital Facility Obligations (it being understood
     that (i) as provided in the definition of "Working Capital Facility Limit"
     in Section 1.01 of the Indenture, such Working Capital Facility Limit"
     shall be reduced by an amount equal to each payment of principal in respect
     of Working

     Capital Facility Secured Obligations made as a result of such turn over and
     (ii) nothing in the foregoing clauses (i) or (ii) shall be deemed to
     prohibit the exercise by the Agent upon any default under the Working
     Capital Facility Agreement of any rights and remedies it may have with
     respect to such Cash Collateral);

          (b) with respect to any Possessory Collateral at any time held by the
     Trustee, the Trustee will deliver any such Possessory Collateral (including
     any shares of Capital Stock or other Equity Interests) held by the Trustee
     in its possession to a bank or trust company in New York City (the
     "Possessory Collateral Intermediary") unaffiliated with either the Trustee
     or the Agent and not constituting a Noteholder or a Working Capital
     Facility Lender pursuant to a control or similar agreement to be entered
     into between the Possessory Collateral Intermediary and the Trustee and
     Agent, which agreement shall provide that each of the Trustee and the Agent
     shall have "control" (as such term is defined in the Uniform Commercial
     Code) over such Possessory Collateral, and confirming that the Lien and
     security interest of the Trustee in such Possessory Collateral shall be
     junior and subordinate to the Lien and security interest of the Agent in
     such Possessory Collateral, provided that such Possessory Collateral may be
     released to the Company or any of its Subsidiaries (and the respective
     agreement with the Possessory Collateral Intermediary shall so provide)
     only upon the joint authorization of the Trustee and the Agent (which the
     Trustee has separately agreed to do upon satisfaction of the conditions in
     Article IX of the Indenture) to the Possessory Collateral Intermediary (it
     being understood that nothing in this proviso shall be deemed to prohibit
     the exercise by the Agent upon default in the payment of any Working
     Capital Facility Obligations of any rights and remedies it may have with
     respect to such Possessory Collateral); and

          (c) with respect to any proceeds of Payment Collateral (including
     amounts paid or collected on account thereof) at any time received,
     collected, or held by the Trustee as a result of the exercise by the
     Trustee of any rights and remedies under the Indenture Security Documents,
     the Trustee agrees to forthwith turn over and transfer any such proceeds of
     Payment Collateral (together with any necessary endorsements) to the Agent
     for application by the Agent to the payment of the Working Capital Facility
     Secured Obligations and the Agent shall apply such proceeds immediately to
     the payment of Working Capital Facility Obligations (it being understood
     that (i) as provided in the definition of "Working Capital Facility Limit"
     in Section 1.01 of the Indenture, such Working Capital Facility Limit"
     shall be reduced by an amount equal to each payment of principal in respect
     of Working Capital Facility Secured Obligations made as a result of such
     turn over and (ii) nothing in the foregoing shall be deemed to prohibit the
     exercise by the Agent upon any default under the Working Capital Facility
     Agreement of any rights and remedies it may have with respect to such
     Payment Collateral).

Pending the execution and delivery of an agreement pursuant to the foregoing
paragraphs (a) or (b), or the transfer or proceeds of Payment Collateral
pursuant to the foregoing paragraph (c), the Trustee hereby agrees that any Cash
Collateral or Possessory Collateral or proceeds of Payment Collateral received
or held by it under the Indenture or the Indenture Security Documents is held by
it also as an agent for the Agent under the Working Capital Facility Security
Documents and

                                      -11-

that the Lien of the Trustee in such Cash Collateral and Possessory Collateral
is subordinate to the Lien of the Agent in such Cash Collateral and Possessory
Collateral.

          In the event that an agreement of the type referred to in paragraph
(a) or (b) above is executed and delivered between the Cash Collateral
Intermediary or Possessory Collateral Intermediary (as applicable), and the
Trustee and the Agent, then the Trustee agrees, except as provided in paragraph
(c) above, that any proceeds of Shared Collateral received by it at any time and
constituting either Cash Collateral or Possessory Collateral shall be forthwith
transferred to the Cash Collateral Intermediary (together with any necessary
endorsements) or Possessory Collateral Intermediary (as applicable) to be held
by the Cash Collateral Intermediary or Possessory Collateral Intermediary in
accordance with the agreement executed and delivered pursuant to said paragraph
(a) or (b) and that, pending such transfer, the Trustee shall be deemed to hold
such Cash Collateral and Possessory Collateral in trust for the benefit of the
Agent and the Working Capital Facility Lenders.

          The parties hereto acknowledge that, pursuant to an Affiliate
Subordination Agreement dated as of the Issue Date between each of the Credit
Parties and the Trustee, all intercompany indebtedness or intercompany accounts
payable or other intercompany obligations at any time owing by any Credit Party
to any other Credit Party is subordinated, inter alia, to all obligations of the
Credit Parties in respect of the Notes, the Note Guarantees and the Working
Capital Facility Agreement and that any payment, purchase, redemption,
defeasance or other acquisition or retirement of any such indebtedness, accounts
payable or obligations is prohibited at any time that an Event of Default shall
have occurred and be continuing, unremedied and unwaived, in respect of the
Indenture. Accordingly, the parties hereto agree that any such payment,
purchase, redemption, defeasance or other acquisition or retirement made after
any such Event of Default shall have occurred and is continuing, unremedied and
unwaived, has been wrongfully made by the Credit Party obligated in respect
thereof and, accordingly, that the proceeds of any such payment, purchase,
redemption, defeasance or other acquisition or retirement received by the
Trustee or the Agent shall be promptly turned over to the Agent or the Trustee,
as applicable, in such proportions as shall be appropriate, so that the benefits
of such payment, purchase, redemption, defeasance or other acquisition or
retirement is shared ratably between the Noteholders and the Working Capital
Facility Lenders hereunder and under any other Working Capital Facility (as
defined in the Indenture) to which the Credit Parties may be party ratably in
accordance with the then outstanding principal amount of Indenture Secured
Obligations, Working Capital Facility Secured Obligations and obligations in
respect of any such other Working Capital Facility. Notwithstanding the
foregoing, it is understood and agreed that the proceeds of any such payment,
purchase, redemption, defeasance or other acquisition or retirement in respect
of Specified Subsidiary Intercompany Claims received by the Agent, shall be
forthwith turned over to the Trustee upon such receipt and shall not be subject
to any obligation on the part of the Trustee to share the same with the Agent or
the Working Capital Facility Lenders.

     administrative resolution or through contractual rights) with respect to,
     the Collateral in which it purports to grant a security interest pursuant
     to Section 3 hereof and no Lien exists upon such Collateral except for

     thereto, the security interest created pursuant hereto constitutes a valid
     security interest in the Collateral in which such Credit Party purports to
     grant a security interest pursuant to Section 3 hereof, which, upon
     perfection of such security interest under applicable law (to the extent

     prohibited and legally possible and not excluded from a perfection
     requirement pursuant to Section 6.02 of the Indenture), will be subject to
     no equal or prior Lien other than Permitted Liens referred to in clauses
     (e), (f), (h), (i), (j), (k), (l), (m), (n) or (o) of the definition of
     such term in Section 1.01 of the Indenture and other than as provided in
     any Intercreditor Agreement.

          (b) Names, Etc. The full and correct legal name, type of organization,
     jurisdiction of organization, organizational ID number (if applicable) and
     mailing address of such Credit Party as of the date hereof are correctly
     set forth in Annex 1. Annex 1 correctly specifies (x) the place of business
     of such Credit Party or, if such Credit Party has more than one place of
     business, the location of the chief executive office of such Credit Party,
     and (y) each country where Equipment, Fixtures, network assets (including
     ducts or cable under IRU's), network equipment, office equipment,
     Inventory, Deposit Accounts, spares and other Goods in excess of $30,000 of
     such Credit Party is located (other than Motor Vehicles constituting
     Equipment, ships, Inventory in transit, Goods in transit and Equipment
     being repaired).

          (c) Changes in Circumstances. Except as specified in Annex 1, such
     Credit Party has not (i) within the period of four months prior to the date
     hereof, changed its "location" (as defined in Section 9-307 of the Uniform
     Commercial Code), (ii) heretofore changed its name, or (iii) heretofore
     become a "new debtor" (as defined in Section 9-102(a)(56) of the Uniform
     Commercial Code) with respect to a currently effective security agreement
     previously entered into by any other Person.

          (d) Pledged Stock. The Pledged Stock, if any, identified under the
     name of such Credit Party in Annex 3 is duly authorized, validly issued,
     fully paid and non-assessable and none of such Pledged Stock is subject to
     any contractual restriction, or any restriction under the charter, by-laws
     or other organizational document of the respective Equity

                            Global Security Agreement

                                       -5-

     Issuer of such Pledged Stock, upon the transfer of such Pledged Stock
     (except for any restriction contained herein or under such organizational
     documents).

          The Pledged Stock, if any, identified under the name of such Credit
     Party in Annex 3 constitutes all the issued and outstanding shares of
     capital stock of whatever class of such Equity Issuer beneficially owned by
     such Credit Party on the date hereof (whether or not registered in the name
     of such Credit Party); Annex 3 correctly identifies, as at the date hereof,
     the respective Equity Issuers of such Pledged Stock and the respective
     class and par value or other identifying characteristics of the shares
     constituting such Pledged Stock and the respective number of shares (and
     registered owners thereof) represented by each such certificate.

          (e) Pledged Indebtedness. The Pledged Indebtedness, if any, identified
     under the name of such Credit Party in Annex 8 constitutes all Indebtedness
     held by any Credit Party that is evidenced by an Instrument and Annex 8
     correctly identifies, as of the date hereof, the respective obligors in
     respect of such Pledged Indebtedness, the amount and maturity thereof, and
     any collateral security or Guarantees therefor.

          (f) Intellectual Property. Annexes 4, 5, and 6, respectively, set
     forth under the name of such Credit Party a complete and correct list of
     all Copyrights, Patents and Trademarks (in each case to the extent
     encompassed within the definition of "Intellectual Property" in Section
     1(b) hereof) owned by such Credit Party on the date hereof, and all
     registrations listed in Annexes 4, 5, and 6, are properly issued and in
     full force and effect. Annex 7 sets forth under the name of such Credit
     Party all licenses and other user agreements pursuant to which such Credit
     Party has been granted the right to use any Copyrights, Patents or
     Trademarks owned by others.

          To such Credit Party's knowledge, (i) except as set forth in Annex 4,
     5 or 6, there is no violation by others of any right of such Credit Party
     with respect to any Copyright, Patent or Trademark listed in Annexes 4, 5,
     and 6, respectively, under the name of such Credit Party and (ii) such
     Credit Party is not infringing upon any copyright, patent or trademark of
     any other Person (other than any other Credit Party, as to which no
     representation or warranty is made) by virtue of the conduct of its
     business; and no proceedings have been instituted, threatened or are
     pending against such Credit Party, and no claim against such Credit Party
     has been received by such Credit Party, alleging any such violation, except
     as may be set forth in Annex 7.

          Section 3. Collateral. As collateral security for the prompt payment
in full when due (whether at stated maturity, by acceleration or otherwise) of
the Secured Obligations, each Credit Party hereby pledges, charges and grants to
the Trustee, for the benefit of the Trustee and the Holders as hereinafter
provided, a security interest in and to all of such Credit Party's right, title
and interest in the following property, whether now owned by such Credit Party

     authority and power of such Equity Issuer with respect to such Equity
     Interests, in each case together with the certificates, instruments and

          IT BEING UNDERSTOOD, HOWEVER, that, notwithstanding anything to the
contrary set forth herein, in the Indenture or any other Security Document (but
without limiting the undertakings of the Credit Parties under Article VI of the
Indenture), in no event shall the Collateral consist of, or the security
interest granted under this Section 3 attach, (A) to any lease, license,
governmental authorization, permit, concession, contract, property rights,
application or agreement to which any Credit Party is a party (or to any of its
rights or interests thereunder) if the grant of such security interest would
constitute or result in either (i) the abandonment, invalidation or
unenforceability of any right, title or interest of any Credit Party therein or
(ii) in a breach, cancellation, withdrawal or termination pursuant to the terms
of, or a default under, any such lease, license, governmental authorization,

Sections 9-406, 9-407, 9-408 or 9-409 of the Uniform Commercial Code or other
applicable law), (B) without limiting the provisions of Section 6.02 of the

approval has not yet been obtained), (C) to any Excluded Collateral or (D) to
any Property located in The Netherlands or, in the case of Receivables, governed
by Netherlands law, and over which a valid security interest is or will be
created by any Dutch Security Document.

          It is contemplated that, with respect to Collateral of any Credit
Party that (x) consists of any real property or real property interest (wherever
located), (y) any Collateral of any Credit Party that may be located outside of
the United States, and (z) any Collateral wherever located of any Credit Party
that may be organized or that conducts business outside of

the United States, such Credit Party will concurrently with the execution and
delivery of this Agreement (but subject to Section 6.02 of the Indenture)
execute and deliver such additional security agreements, pledge agreements,
assignments, mortgages and other similar instruments or documents as shall be
necessary or appropriate (and permitted under applicable law) in order to
create, perfect and make enforceable Liens upon and other security interests in
the Collateral owned by such Credit Party under the law of the jurisdiction in
which such Collateral is located or in which such Credit Party is organized or
conducts business. Any such additional security agreements, pledge agreements,
assignments, mortgages and similar instruments and documents shall be deemed to
supplement and not supersede the Liens and security interests provided herein.

          Anything herein to the contrary notwithstanding, no Credit Party shall
be required to perform any action which is illegal or which may violate any
applicable law or that carries a material risk of jeopardizing the rights it
holds in the Collateral.

          Section 4. Further Assurances; Remedies. In furtherance of the grant
of the pledge, charge and security interest pursuant to Section 3 hereof, the
Credit Parties hereby jointly and severally agree with the Trustee (but subject
to the provisions of Section 6.02 of the Indenture) as follows:

          4.01 Delivery and Other Perfection. Each Credit Party shall:

          (a) if any of the shares, securities, moneys or property required to
     be pledged and charged by such Credit Party under clauses (c)(i) and
     (c)(ii) of Section 3 hereof are received by such Credit Party forthwith,
     either (x) transfer and deliver to the Trustee (or to the Agent or third
     party under any Intercreditor Agreement as provided in Article III thereof)
     such shares, securities, moneys or property so received by such Credit
     Party (together with the certificates, if any, for any such shares and
     securities duly endorsed in blank or accompanied by undated stock powers
     duly executed in blank), all of which thereafter shall be held by the
     Trustee (or the Agent or third party), pursuant to the terms of this
     Agreement, as part of the Collateral or (y) take such other action as shall
     be necessary to duly record the Lien created hereunder in such shares,
     securities, moneys or property in said clauses (c)(i) and (c)(ii),
     including, with respect to the Lien on the shares of an Equity Issuer which
     are not represented by certificates, the registration in the shareholders
     register of such Equity Issuer of appropriate entries evidencing said Lien;

          (b) deliver and pledge to the Trustee (or to the Agent or third party
     under any Intercreditor Agreement as provided in Article III thereof) any
     and all Instruments (other than checks) constituting part of the Collateral
     in which such Credit Party purports to grant a security interest hereunder,
     endorsed and/or accompanied by such instruments of assignment and transfer
     in such form and substance necessary to effectuate the security interest
     granted hereunder; provided, that so long as no Event of Default shall have
     occurred and be continuing, unremedied and unwaived, such Credit Party may
     retain for collection in the ordinary course any Instruments received by
     such Credit Party in the ordinary course of its business and the Trustee
     shall, promptly upon request of such Credit Party through the Company, make
     arrangements against trust receipt or like

                            Global Security Agreement

<PAGE>

                                       -9-

     document for making any Instrument pledged by such Credit Party available
     to such Credit Party for purposes of presentation, collection or renewal;

          (c) deliver and pledge to the Trustee (or to the Agent or third party
     under any Intercreditor Agreement as provided in Article III thereof) any
     and all promissory notes or other instruments constituting part of the
     Collateral and evidencing any of the Pledged Indebtedness in excess of
     $200,000, endorsed and/or accompanied by such instruments of assignment and
     transfer in such form as shall be necessary to perfect the Lien of the
     Trustee in such promissory notes and instruments;

          (d) give, execute, deliver, file, record, authorize or obtain all such
     financing statements, notices, instruments, documents, agreements or
     consents or other papers as, subject to Section 6.02 of the Indenture,
     shall be necessary to create, preserve, perfect or validate the security
     interest granted pursuant hereto and the priority thereof or to enable the
     Trustee to exercise and enforce its rights hereunder with respect to such
     security interest, including, without limitation, causing any or all of the
     Stock Collateral to be transferred of record into the name of the Trustee
     or its nominee (and the Trustee agrees that if any Stock Collateral is
     transferred into its name or the name of its nominee, the Trustee will
     thereafter promptly upon request therefor by the Company give to such
     Credit Party copies of any notices and communications received by it with
     respect to the Stock Collateral pledged and charged by such Credit Party
     hereunder);

          (e) keep accurate books and records relating to the Collateral, and
     stamp or otherwise mark such books and records in such manner as shall be
     necessary in order to reflect the security interests granted by this
     Agreement;

          (f) following the occurrence and during the continuance, unremedied
     and unwaived, of an Event of Default, permit representatives of the
     Trustee, upon reasonable notice, at any time during normal business hours
     to inspect and make abstracts from its books and records pertaining to the
     Collateral, and permit representatives of the Trustee to be present at such
     Credit Party's place of business to receive copies of all communications
     and remittances relating to the Collateral, and forward copies of any
     notices or communications received by such Credit Party with respect to the
     Collateral, all in such manner as the Trustee may reasonably require; and

          (g) subject to Section 6.02 of the Indenture, execute and deliver and
     cause to be filed, such continuation statements, and do such other acts and
     things, as may be necessary to maintain the perfection and priority of the
     security interest granted pursuant hereto.

          Anything herein to the contrary notwithstanding, it is understood and
agreed that, as provided in Section 6.03(a) of the Indenture:

          (i) as to Property of any Credit Party located in any jurisdiction
     owned by such Credit Party on the date hereof that is not covered by the
     Lien of a particular Security Document other than this Agreement, such
     Credit Party shall be deemed to have complied with the requirements of this
     Section 4.01 if, as contemplated by Exhibit F to

                            Global Security Agreement

<PAGE>

                                      -10-

     the Indenture, the Administrative Agent and the Official Creditors'
     Committee confirm in writing to the Trustee that the conditions set forth
     in said Exhibit F have been satisfied;

          (ii) as to Property of any Credit Party located in any jurisdiction,
     whether now owned or hereafter acquired, that is covered by the Lien of a
     particular Security Document other than this Agreement (or that is
     contemplated by such Security Document to be covered by such Lien if
     acquired after the date hereof), such Credit Party shall be deemed to have
     complied with the requirements of this Section 4.01 if such Credit Party
     complies with the requirements of such Security Document;

          (iii) as to all other Property hereafter acquired by any Credit Party,
     such Credit Party shall (subject to Section 6.02 of the Indenture) comply
     with the requirements of this Section 4.01;

          (iv) as to any contract or agreement to which any Credit Party is a
     party on the date hereof that requires the consent of a third party in
     order to create a lien in such contract or agreement, such Credit Party
     shall be deemed to have complied with the requirements of this Section 4.01
     if, after utilizing commercially reasonable efforts in an attempt to so
     obtain such consent, as contemplated by Exhibit F to the Indenture, the
     Administrative Agent and the Official Creditors' Committee confirm in
     writing to the Trustee that the conditions set forth in said Exhibit F have
     been satisfied; and

          (v) as to any contract or agreement to which any Credit Party becomes
     a party after the date hereof that requires the consent of a third party in
     order to create a Lien in such contract or agreement, such Credit Party
     shall be deemed to have complied with the requirements of this Section
     4.01, notwithstanding that such consent has been refused, if it shall have
     used commercially reasonable efforts to obtain such consent (and shall so
     certify in the first Officers' Certificate delivered pursuant to Section
     6.03(c)(ii)(B) of the Indenture after the date of such refusal).

          4.02 Other Financing Statements and Liens. Except for Permitted Liens,
no Credit Party shall (i) file or suffer to be on file, or authorize or permit
to be filed or to be on file, in any jurisdiction, any financing statement or
like instrument or (ii) create or permit the creation of any Lien or allow any
Lien to subsist, with respect to the Collateral in which the Trustee is not
named as the sole secured party for the benefit of the Trustee and the Holders.

          4.03 Preservation of Rights. The Trustee shall not be required to take
steps necessary to preserve any rights against prior parties to any of the
Collateral, provided that the Trustee shall cooperate with the Credit Parties in
any request for documentation or evidence in any action taken by a Credit Party
to protect or preserve its rights in the Collateral, to the extent such request
is made pursuant to an Issuer Order.

          4.04 Special Provisions Relating to Certain Collateral.

          (a) Stock Collateral. The Credit Parties will cause the Stock
Collateral to constitute at all times 100% of all the total number of shares of
Capital Stock of each Equity Issuer then issued and outstanding held by the
Credit Parties.

                            Global Security Agreement

<PAGE>

                                      -11-

          So long as no Event of Default shall have occurred and be continuing,
unremedied and unwaived, the Credit Parties shall have the right to exercise all
voting, consensual and other powers of ownership pertaining to the Stock
Collateral for all purposes not inconsistent with the terms of this Agreement,
the Indenture or any other Security Document or any other instrument or
agreement referred to herein or therein, provided that the Credit Parties
jointly and severally agree that they will not vote the Stock Collateral in any
manner that results in a violation of the terms of this Agreement, the
Indenture, the Security Documents or any such other instrument or agreement; and
the Trustee shall execute and deliver to the Credit Parties or cause to be
executed and delivered to the Credit Parties all such proxies, powers of
attorney, dividend and other orders, and all such instruments, without recourse,
as the Credit Parties may reasonably request pursuant to an Issuer Request for
the purpose of enabling the Credit Parties to exercise the rights and powers
that they are entitled to exercise pursuant to this Section 4.04.

          (b) Intellectual Property. Notwithstanding the pledge of its
Intellectual Property hereunder and any requirement contained in the Indenture
or any other Security Document, until notice to the Credit Parties has been
given by the Trustee following the occurrence and during the continuance,
unremedied and unwaived, of an Event of Default, each Credit Party shall have
the right to exploit and use the Intellectual Property in connection with its
business, including but not limited to the development, marketing, promotion,
distribution and sale of the underlying services related to such Intellectual
Property.

          4.05 Events of Default, Etc. During the period during which an Event
of Default shall have occurred and be continuing, unremedied and unwaived:

          (a) each Credit Party shall, at the request of the Trustee, assemble
     the Collateral owned by it at such place or places, reasonably convenient
     to both the Trustee and such Credit Party, designated in the Trustee's
     request;

          (b) the Trustee may make any reasonable compromise or settlement
     deemed desirable with respect to any of the Collateral and may extend the
     time of payment, arrange for payment in installments, or otherwise modify
     the terms of, any of the Collateral;

          (c) the Trustee shall have all of the rights and remedies with respect
     to the Collateral of a secured party under the Uniform Commercial Code
     (whether or not the Uniform Commercial Code is in effect in the
     jurisdiction where the rights and remedies are asserted) and such
     additional rights and remedies to which a secured party is entitled under
     the laws in effect in any jurisdiction where any rights and remedies
     hereunder or under any of the other Security Documents may be asserted,
     including the right, to the fullest extent permitted by applicable law, to
     exercise all voting, consensual and other powers of ownership pertaining to
     the Collateral as if the Trustee were the sole and absolute owner thereof
     (and each Credit Party agrees to take all such action as may be appropriate
     to give effect to such right);

          (d) the Trustee may, in its name or in the name of any Credit Party or
     otherwise, demand, sue for, collect or receive any money or property at any
     time payable or

                            Global Security Agreement

<PAGE>

                                      -12-

     receivable on account of or in exchange for any of the Collateral, but
     shall be under no obligation to do so; and

          (e) the Trustee may, upon ten Business Days' prior written notice to
     the Credit Parties of the time and place, with respect to the Collateral or
     any part thereof which shall then be or shall thereafter come into the
     possession, custody or control of the Trustee, or any of its agents, sell,
     lease, assign or otherwise dispose of all or any part of such Collateral,
     at such place or places as the Trustee deems best, and for cash or for
     credit or for future delivery (without thereby assuming any credit risk),
     at public or private sale, without demand of performance or notice of
     intention to effect any such disposition or of the time or place thereof
     (except such notice as is required above or by applicable statute and
     cannot be waived), and the Trustee or any other Holder or anyone else may
     be the purchaser, lessee, assignee or recipient of any or all of the
     Collateral so disposed of at any public sale (or, to the extent permitted
     by law, at any private sale) and thereafter, to the fullest extent
     permitted by law, hold the same absolutely, free from any claim or right of
     whatsoever kind, including any right or equity of redemption (statutory or
     otherwise), of the Credit Parties, any such demand, notice and right or
     equity being hereby expressly waived and released, to the fullest extent
     permitted by law. The Trustee may, without notice or publication, adjourn
     any public or private sale or cause the same to be adjourned from time to
     time by announcement at the time and place fixed for the sale, and such
     sale may be made at any time or place to which the sale may be so
     adjourned.

          In the event of any sale, assignment, or other disposition of any of
     the Trademark Collateral, the goodwill connected with and symbolized by the
     Trademark Collateral subject to such disposition shall be included, and the
     Credit Parties shall supply to the Trustee or its designee, for inclusion
     in such sale, assignment or other disposition, all Intellectual Property
     relating to such Trademark Collateral.

The proceeds of each collection, sale or other disposition under this Section
4.05 shall be applied in accordance with Section 4.09 hereof.

          The Credit Parties recognize that, by reason of certain prohibitions
contained in the Securities Act of 1933, as amended, and applicable state
securities laws, the Trustee may be compelled, with respect to any sale of all
or any part of the Collateral, to limit purchasers to those who will agree,
among other things, to acquire the Collateral for their own account, for
investment and not with a view to the distribution or resale thereof. The Credit
Parties acknowledge that any such private sales may be at prices and on terms
less favorable to the Trustee than those obtainable through a public sale
without such restrictions, and, notwithstanding such circumstances, agree that
any such private sale shall be deemed to have been made in a commercially
reasonable manner and that the Trustee shall have no obligation to engage in
public sales and no obligation to delay the sale of any Collateral for the
period of time necessary to permit the Credit Parties or issuer thereof to
register it for public sale.

          4.06 Deficiency. If the proceeds of sale, collection or other
realization of or upon the Collateral pursuant to Section 4.05 hereof are
insufficient to cover the costs and expenses of such realization and the payment
in full of the Secured Obligations, the Credit Parties shall remain liable for
any deficiency.

                                      -13-

          4.07 Locations; Names. Without at least 30 days' prior written notice
to the Trustee, and (in the case of a change of its name) delivery of an Opinion
of Counsel and an Issuer Order identifying any action required to be taken by
such Credit Party or the Trustee to perfect or continue the perfection of the
Liens hereunder granted by such Credit Party and protect the priority thereof,
no Credit Party shall change its "location" (as defined in Section 9-307 of the
Uniform Commercial Code) or change its name from the name shown as its current
legal name on Annex 1.

          Without the prior written consent of the Trustee, any Credit Party may
remove items of Collateral outside of any jurisdiction in which such Credit
Party conducts business, or in which such items are located, in order to have
them repaired or upgraded, subject to the obligation of returning such items to
their original location in such jurisdiction as soon as their repair or upgrade
has been completed and, if required in order to transport or relocate any such
item of Collateral, the Trustee shall, upon delivery to it of an Issuer Order
requesting a release (which shall state that such release is authorized under
this Section 4.07), promptly execute and deliver to such Credit Party such
release statement and such other documentation as shall be specified by such
Credit Party in such Issuer Order to effect the temporary release of the Lien on
such item of Collateral in order that it may be removed or relocated.

          4.08 Private Sale. The Trustee and the Holders shall incur no
liability as a result of the sale of the Collateral, or any part thereof, at any
private sale pursuant to Section 4.05 hereof conducted in a commercially
reasonable manner. Each Credit Party hereby waives any claims against the
Trustee or any Holder arising by reason of the fact that the price at which the
Collateral may have been sold at such a private sale was less than the price
which might have been obtained at a public sale or was less than the aggregate
amount of the Secured Obligations, even if the Trustee accepts the first offer
received and does not offer the Collateral to more than one offeree.

          4.09 Application of Proceeds. The proceeds of any collection, sale or
other realization of all or any part of the Collateral pursuant hereto, and any
other cash at the time held by the Trustee under this Section 4, shall be
applied by the Trustee in the manner set forth in Article IX of the Indenture.

          4.10 Attorney-in-Fact. Without limiting any rights or powers granted
by this Agreement to the Trustee while no Event of Default has occurred and is
continuing, upon the occurrence and during the continuance, unremedied and
unwaived, of any Event of Default the Trustee is hereby appointed the
attorney-in-fact of each Credit Party for the purpose of carrying out the
provisions of this Section 4 and taking any action and executing any instruments
which the Trustee may reasonably deem necessary or advisable to accomplish the
purposes hereof, which appointment as attorney-in-fact is irrevocable and
coupled with an interest. Without limiting the generality of the foregoing, so
long as the Trustee shall be entitled under this Section 4 to make collections
in respect of the Collateral, the Trustee shall have the right and power to
receive, endorse and collect all checks made payable to the order of any Credit
Party representing any dividend, payment or other distribution in respect of the
Collateral or any part thereof and to give full discharge for the same.

                            Global Security Agreement

<PAGE>

                                      -14-

          4.11 Perfection. Each Credit Party consents that Uniform Commercial
Code financing statements may be filed describing the Collateral as "all assets"
or "all personal property" of such Credit Party (provided that no such
description shall be deemed to modify the description of Collateral set forth in
Section 3 hereof).

          Anything herein to the contrary notwithstanding, the obligations of
the Credit Parties to take any action to perfect the Liens granted hereunder and
under any other Security Document on any Collateral shall be subject to the
provisions of Sections 6.02 and 6.03 of the Indenture.

          4.12 Certain Releases of Collateral.

          (a) Releases Upon Asset Sales, Etc. If at any time a Credit Party
consummates an Asset Sale, a Specified Subsidiary Asset Sale, or a Qualified
Receivables Transaction, in accordance with the terms of the Indenture and
satisfies all of the conditions precedent set forth in Section 6.05(b) of the
Indenture with respect thereto, the Trustee shall, upon the request of such
Credit Party, execute, deliver or acknowledge any necessary or proper
instruments of termination, satisfaction or release prepared by such Credit
Party reasonably required to effect the release of the Liens on the Collateral
which is the subject of such Asset Sale, Specified Subsidiary Asset Sale, or
Qualified Receivables Transaction.

          (b) Releases Upon Other Asset Sales. If at any time a Credit Party
sells, transfers, leases, conveys, substitutes, converts, abandons or otherwise
disposes of any item of Collateral in a transaction (i) not deemed to be an
Asset Sale under the Indenture as set forth in clauses (a) through (f),
inclusive, and (h) of the definition of "Asset Sale" therein or (ii) otherwise
permitted under the Indenture and for which such Credit Party has complied with
all requirements in respect thereof (each such transaction listed in clause (i)
and (ii) hereinabove, a "Permitted Sale"), any Lien on such item of Collateral
shall be automatically released and, if a formal, documented termination of

          Accordingly, upon the execution and delivery of any such Guarantee
Supplement by any such Subsidiary, such Subsidiary shall automatically and
immediately, and without any further action on the part of any Person, become a
"Guarantor" and a "Credit Party" for all purposes of this Agreement, and Annexes

          (b) except as expressly instructed by the Holders or the Issuer or any
     other Credit Party, the Trustee shall have no obligation to give, execute,
     deliver, file, record, authorize or obtain any financing statements,
     notices, instruments, documents, agreements, consents or other papers as
     shall be necessary to create, preserve, perfect or validate the security

     enforce its rights hereunder with respect to such pledge and security
     interest, and the Trustee have no responsibility or liability (i) in
     connection with the acts or omissions of the Credit Parties in respect of
     the foregoing or (ii) for or with respect to the legality, validity and
     enforceability of any security interest created in the Collateral or the
     perfection and priority of such security interest; and

          (c) the Trustee shall have no obligation to obtain title to any piece
     of real property by foreclosure, deed in lieu of foreclosure or otherwise,
     or take any other action with respect to any real property, if, in its
     reasonable, good faith judgment, it shall determine that, as a result of
     such action, the Trustee would be liable, in its individual capacity for
     any environmental liability in connection with, or responsibility for the
     clean-up or remediation of, such real property under any applicable
     environmental laws and regulations.

provided in the applicable Intercreditor Agreement.

except to the extent otherwise provided in Section 7.06 of the Indenture, each
Holder agrees that this

upon the Collateral or other security given to secure the payment and
performance of the Secured Obligations.

FARGO BANK MINNESOTA, N.A., as trustee and agent under the below-referenced
Indenture (in such capacity, together with its successors in such capacity, the

          Pursuant to an Indenture dated as of               , 2003 (as modified
                                               --------------
and supplemented and in effect from time to time, the "Indenture") by and
between the Credit Parties and the Trustee for the benefit of the holders of the
Notes (as hereinafter defined), the Issuer has issued $200,000,000 of its 11%
Senior Secured Notes due 2006 (the "Notes") and the Guarantors have
unconditionally guaranteed all of the obligations of the Issuer under and in
respect of the Notes.

          To induce the holders of the Notes to accept the same on the terms and
conditions as provided in the Indenture, and in accordance with Section

     modified and supplemented from time to time, and including all agreements
     extending, renewing or refinancing the same); and

          (b) all interest accruing after the commencement of any proceedings
     referred to in Section 2.01(ii) below, whether or not such interest is an
     allowed claim in such proceeding.

Credit Party and its successors and assigns, the "Affiliate Holder"), and the
payment from whatever source of the principal of, and interest and premium (if
any) on, such Subordinated Indebtedness, are hereby expressly made subordinate
and subject in right of payment to the prior payment in full in cash of all
Senior Indebtedness:

          (i) The holders of Senior Indebtedness shall be entitled to receive
     payment in full in cash of all amounts constituting Senior Indebtedness
     before such Affiliate Holder is entitled to receive any payment on account
     of the Subordinated Indebtedness held by it (and unless and until all
     Senior Indebtedness has been so paid, such Affiliate Holder will not (x)
     ask, demand, sue for, take or receive from any Credit Party obligated in
     respect of such Subordinated Indebtedness (each, a "Credit Party Obligor"),
     by set-off or in any other manner, or (y) seek any other remedy allowed at
     law or in equity against any Credit Party Obligor for breach of such Credit
     Party Obligor's obligations under any Subordinated Indebtedness Document,
     provided that, so long as at the time thereof and after giving effect
     thereto no Event of Default shall have occurred and be continuing,
     unremedied and unwaived, under the Indenture, any Credit Party Obligor may
     make, and such Affiliate Holder shall be entitled to receive and retain,
     payments in respect of the principal of and interest of the Subordinated
     Indebtedness.

          (ii) In the event of any insolvency or bankruptcy proceedings, and any
     receivership, liquidation, reorganization or other similar proceedings in
     connection therewith, relative to any Credit Party Obligor or to its
     creditors, as such, or to its property, and in the event of any proceedings
     for voluntary liquidation, dissolution or other winding up of any Credit
     Party Obligor, whether or not involving insolvency or bankruptcy, then the
     holders of Senior Indebtedness shall be entitled to receive payment in full
     of all amounts constituting Senior Indebtedness before such Affiliate
     Holder is entitled to receive, or make any demand for, any payment on
     account of the Subordinated Indebtedness, and to that end the holders of
     Senior Indebtedness shall be entitled to receive for application in payment
     thereof any payment or distribution of any kind or character, whether in
     cash or property or securities.

<PAGE>

                                      -3-

          (iii) If any payment or distribution of any character, whether in
     cash, securities or other property, in respect of any Subordinated
     Indebtedness shall (despite these subordination provisions) be received by
     such Affiliate Holder before all Senior Indebtedness shall have been paid
     in full in cash, such payment or distribution shall be held in trust for
     the benefit of, and shall be paid over or delivered to, the holders of
     Senior Indebtedness (or their representatives), and to holders of any other
     Indebtedness to which the Subordinated Indebtedness is similarly
     subordinated, ratably according to the respective aggregate amounts
     remaining unpaid thereon, to the extent necessary to pay all Senior
     Indebtedness, and all such other Indebtedness, in full.

          No present or future holder of Senior Indebtedness shall be prejudiced
in its right to enforce subordination of any Subordinated Indebtedness or any
Subordinated Indebtedness Document by any act or failure to act on the part of
any Credit Party Obligor or by any act or failure to act, in good faith on the
part of such holder or any trustee or agent for such holder. The foregoing
provisions are solely for the purpose of defining the relative rights of the
holders of Senior Indebtedness on the one hand, and each Affiliate Holder on the
other hand, and nothing herein shall impair, as between any Credit Party Obligor
and any Affiliate Holder, the obligation of such Credit Party Obligor, which is
unconditional and absolute, to pay to such Affiliate Holder any principal of
Subordinated Indebtedness and interest thereon in accordance with the terms of
any Subordinated Indebtedness Document.

          2.02 Subrogation. Subject to the payment in full in cash of all Senior
Indebtedness, each Affiliate Holder shall be subrogated to the rights of the
holders of such Senior Indebtedness to receive payments and distributions of
cash, property and securities applicable to the Senior Indebtedness until the
principal of, and interest on, the Subordinated Indebtedness held by such
Affiliate Holder shall be paid in full in cash. For purposes of such
subrogation, no payments or distributions to the holders of Senior Indebtedness
of any cash, property or securities to which any Affiliate Holder would be
entitled except for the provisions of Section 2.01, and no payments over
pursuant to the provisions of Section 2.01 to the holders of Senior Indebtedness
by any Affiliate Holder, shall, as between the applicable Credit Party Obligor,
its creditors other than holders of Senior Indebtedness, and such Affiliate
Holder, be deemed to be a payment or distribution by such Credit Party Obligor
to or on account of the Senior Indebtedness.

          2.03 Defaults. If after payment in full in cash of the Senior
Indebtedness, any payment of Subordinated Indebtedness is not made when due or
any other event of default shall occur in respect of such Subordinated
Indebtedness, the applicable Affiliate Holder may declare all amounts owing in
respect of such Subordinated Indebtedness due and payable, provided that if
after repayment in full of the Senior Indebtedness, any payments of Senior
Indebtedness shall at any time be rescinded or otherwise must be returned by the
holder of any Senior Indebtedness, such demand, if made, shall be automatically
rescinded.

          3.01 Notices. All notices, waivers, requests, consents, demands,

                                   ARTICLE ONE

                                   DEFINITIONS

from time to time, and including all agreements extending, renewing or
refinancing the same), (c) all other Indebtedness of the [Credit Party] for

modified and supplemented from time to time, and including all agreements
extending, renewing or refinancing the same) and (d) all interest accruing after
the commencement of any bankruptcy or insolvency proceedings, whether or not

          Section 2.01. Subordinated Debt Instruments Subordinated to Senior
Indebtedness.

          The [Credit Party] covenants and agrees, and [the Subordinated Debt

          Section 2.02. No Payment on Subordinated Debt Instruments in Certain
Circumstances.

          (a) Payment Blockage. No direct or indirect payment (excluding any
payment or distribution of Permitted Junior Securities) by or on behalf of the
[Credit Party] of principal of or interest on the Subordinated Debt Instruments,
whether pursuant to the terms of the Subordinated Debt Instruments, upon
acceleration, pursuant to an offer to purchase or otherwise, shall be made if,
at the time of such payment, there exists a default in the payment of all or any
portion of the obligations on any Designated Senior Indebtedness, whether at
maturity, on account of mandatory redemption or prepayment, acceleration or
otherwise, and such default shall not have been cured or waived or the benefits
of this sentence waived by or on behalf of the holders of such Designated Senior
Indebtedness. In addition, during the continuance of any non-payment event of
default with respect to any Designated Senior Indebtedness pursuant to which the
maturity thereof may be immediately accelerated, and upon receipt by the
[Debtholders] [Subordinated Debt Trustee] of written notice (a "Payment Blockage
Notice") from the holder or holders of such Designated Senior Indebtedness or a
trustee or agent acting on behalf of such Designated Senior Indebtedness, then,
unless and until such non-payment event of default has been cured or waived or
has ceased to exist or such Designated Senior Indebtedness has been discharged
or repaid in full in cash or the benefits of these provisions have been waived
by the holders of such Designated Senior Indebtedness, no direct or indirect
payment (excluding any payment or distribution of Permitted Junior Securities)
shall be made by or on behalf of the [Credit Party] of principal of or interest
on the Subordinated Debt Instruments, to such holders, during a period (a
"Payment Blockage Period") commencing on the date of receipt of such notice by
[the Debtholders] [the Subordinated Debt Trustee] and ending 179 days
thereafter.

          Notwithstanding anything herein or in the Subordinated Debt
Instruments to the contrary, (x) in no event shall a Payment Blockage Period
extend beyond 179 days from the date the Payment Blockage Notice in respect
thereof was given, (y) there shall be a period of at least 181 consecutive days
in each 360-day period when no Payment Blockage Period is in effect and (z) not
more than one Payment Blockage Period may be commenced with respect to the
Subordinated Debt Instruments during any period of 360 consecutive days. No
non-payment event of default that existed or was continuing on the date of
commencement of any Payment Blockage Period with respect to the Designated
Senior Indebtedness initiating such Payment Blockage Period (to the extent the
holder of Designated Senior Indebtedness, or trustee or agent, giving notice
commencing such Payment Blockage Period had knowledge of such existing or
continuing event of default) may be, or be made, the basis for the commencement
of any other Payment Blockage Period by the holder or holders of such Designated
Senior Indebtedness or a trustee or agent acting on behalf of such Designated
Senior Indebtedness, whether or not within a period of 360 consecutive days,
unless such non-payment event of default has been cured or waived for a period
of not less than 90 consecutive days.

          (b) Payments Held in Trust. In the event that, notwithstanding the
foregoing, either

          (i) the [Credit Party] shall have made payment to [the Subordinated
     Debt Trustee or] any Debtholder when such payment is prohibited by Section
     2.02(a), or

          (ii) if during any Payment Blockage Period [the Subordinated Debt
     Trustee or] any Debtholder shall receive any payment representing the
     proceeds of a turnover to [the Subordinated Debt Trustee or] any Debtholder
     of a payment made in respect of an obligation that is subordinated to the
     Subordinated Debt Instruments,

then in each such case such payment shall be held in trust for the benefit of,
and shall be paid over or delivered by [the Subordinated Debt Trustee (if the
notice required by Section 2.06 has been received by the Subordinated Debt
Trustee) or] such Debtholder to, holders of Designated Senior Indebtedness or
their respective representatives, or to the trustee or trustees under any
indenture pursuant to which any of such Designated Senior Indebtedness may have
been issued, as their respective interests may appear[, but only to the extent
that, upon notice from the Subordinated Debt Trustee to the holders of
Designated Senior Indebtedness that such prohibited payment has been made, the
holders of the Designated Senior Indebtedness (or their representative or
representatives or a trustee or trustees) notify the Subordinated Debt Trustee
in writing of the amounts then due and owing on the Designated Senior
Indebtedness, if any, and only the amounts specified in such notice to the
Subordinated Debt Trustee shall be paid to the holders of Designated Senior
Indebtedness]/1/.

          Section 2.03. Payment Over of Proceeds upon Dissolution, etc.

          (a) Payment Over upon Dissolution. Upon any payment or distribution of
assets or securities of the [Credit Party] of any kind or character, whether in
cash, property or securities (excluding any payment or distribution of Permitted
Junior Securities), upon any dissolution or winding-up or total liquidation or
reorganization of the [Credit Party], whether voluntary or involuntary or in
bankruptcy, insolvency, receivership or other proceedings, all Senior
Indebtedness shall first be paid in full in cash before the holders of the
Subordinated Debt Instruments [or the Subordinated Debt Trustee on behalf of
such holders] shall be entitled to receive any payment by the [Credit Party] of
the principal of or interest on the Subordinated Debt Instruments, or any
payment by the [Credit Party] to acquire any of the Subordinated Debt
Instruments for cash, property or securities, or any distribution with respect
to the Subordinated Debt Instruments of any cash, property or securities
(excluding any payment or distribution of Permitted Junior Securities). Before
any payment may be made by, or on behalf of, the [Credit Party] of the principal
of or interest on the Subordinated Debt Instruments upon any such dissolution or
winding-up or total liquidation or reorganization, any payment or distribution
of assets or securities of the [Credit Party] of any kind or character, whether
in cash, property or securities (excluding any payment or distribution of
Permitted Junior Securities), to which the holders of the Subordinated Debt
Instruments [or the Subordinated Debt Trustee on their behalf] would be
entitled, but for the subordination provisions of this [Subordinated Debt
Agreement],

shall be made by the [Credit Party] or by any receiver, trustee in bankruptcy,
liquidation trustee, agent or other Person making such payment or distribution,
directly to the holders of the Senior Indebtedness (pro rata to such holders on
the basis of the respective amounts of Senior Indebtedness held by such holders)
or their representatives or to the trustee or trustees or agent or agents under
any agreement or [Subordinated Debt Agreement] pursuant to which any of such
Senior Indebtedness may have been issued, as their respective interests may
appear, to the extent necessary to pay all such Senior Indebtedness in full in
cash after giving effect to any prior or concurrent payment, distribution or
provision therefor to or for the holders of such Senior Indebtedness.

          (b) Payments Held in Trust. In the event that, notwithstanding the
foregoing provision prohibiting such payment or distribution, if before all
obligations in respect of Senior Indebtedness are paid in full in cash either

          (i) any payment or distribution of assets or securities of the [Credit
     Party] of any kind or character, whether in cash, property or securities
     (excluding any payment or distribution of Permitted Junior Securities),
     shall be paid by the [Credit Party] to [the Subordinated Debt Trustee or]
     any holder of the Subordinated Debt Instruments or

          (ii) [the Subordinated Debt Trustee or] any Debtholder shall receive
     any payment representing the proceeds of a turnover to [the Subordinated
     Debt Trustee or] any Debtholder of a payment made in respect of an
     obligation that is subordinated to the Subordinated Debt Instruments,

in either case at a time when such payment or distribution is prohibited by

          Section 2.04. Subrogation.

          Upon the payment in full in cash of all Senior Indebtedness, or
provision for payment, the holders of the Subordinated Debt Instruments shall be
subrogated to the rights of the holders of Senior Indebtedness to receive
payments or distributions of cash, property or securities of the [Credit Party]
made on such Senior Indebtedness until the principal of and interest on the
Subordinated Debt Instruments shall be paid in full in cash; and, for the
purposes of such subrogation, no payments or distributions to the holders of the
Senior Indebtedness of any cash, property or securities to which the holders of
the Subordinated Debt Instruments [or the Subordinated Debt Trustee on their
behalf] would be entitled except for the provisions of this Article Two, and no
payment over pursuant to the provisions of this Article Two to the holders of
Senior Indebtedness by holders of the Subordinated Debt Instruments [or the
Subordinated Debt Trustee on their behalf] shall, as between the [Credit Party],
its creditors other than holders of Senior Indebtedness, and the holders of the
Subordinated Debt Instruments, be deemed to be a payment by the [Credit Party]
to or on account of the Senior Indebtedness. It is understood that the
provisions of this Article Two are and are intended solely for the purpose of
defining the relative rights of the holders of the Subordinated Debt
Instruments, on the one hand, and the holders of the Senior Indebtedness, on the
other hand.

          If any payment or distribution to which the holders of the
Subordinated Debt Instruments would otherwise have been entitled but for the
provisions of this Article Two shall have been applied, pursuant to the
provisions of this Article Two, to the payment of all amounts payable under
Senior Indebtedness, then and in such case, the holders of the Subordinated Debt
Instruments shall be entitled to receive from the holders of such Senior
Indebtedness any payments or distributions received by such holders of Senior
Indebtedness in excess of the amount required to make payment in full in cash of
such Senior Indebtedness.

          Section 2.05. Obligations of [Credit Party] Unconditional.

          Nothing contained in this Article Two or elsewhere in this
[Subordinated Debt Agreement] or in the Subordinated Debt Instruments is
intended to or shall impair, as among the [Credit Party] and the holders of the
Subordinated Debt Instruments, the obligation of the [Credit Party], which is
absolute and unconditional, to pay the holders of the Subordinated Debt
Instruments the principal of and interest on the Subordinated Debt Instruments
as and when the same shall become due and payable in accordance with their
terms, or is intended to or shall affect the relative rights of the holders of
the Subordinated Debt Instruments and creditors of the [Credit Party] other than
the holders of the Senior Indebtedness, nor shall anything herein or therein
prevent the holders of any Subordinated Debt Instrument [or the Subordinated
Debt Trustee on their behalf] from exercising all remedies otherwise permitted
by applicable law upon default under this [Subordinated Debt Agreement], subject
to the rights, if any, under this Article Two of the holders of the Senior
Indebtedness in respect of cash, property or securities of the [Credit Party]
received upon the exercise of any such remedy.

          Without limiting the generality of the foregoing, nothing contained in
this Article Two shall restrict the right of [the Subordinated Debt Trustee or]
the holders of Subordinated Debt Instruments to take any action to declare the
Subordinated Debt Instruments to be due and

payable prior to their stated maturity or to pursue any rights or remedies
hereunder; provided, however, that all Senior Indebtedness then due and payable
shall first be paid in full in cash before the holders of the Subordinated Debt
Instruments [or the Subordinated Debt Trustee on their behalf] are entitled to
receive any direct or indirect payment from the [Credit Party] of principal of
or interest on the Subordinated Debt Instruments.

          Section 2.06. Notice to [Debtholders] [Subordinated Debt Trustee].

          The [Credit Party] shall give prompt written notice to the
[Debtholders] [Subordinated Debt Trustee] of any fact known to the [Credit
Party] which would prohibit the making of any payment to [the Debtholders] [or
by the Subordinated Debt Trustee] in respect of the Subordinated Debt
Instruments pursuant to the provisions of this Article Two. The [Debtholders]
[Subordinated Debt Trustee] shall not be charged with knowledge of the existence
of any event of default with respect to any Senior Indebtedness or of any other
facts which would prohibit the making of any payment to [the Debtholders] [or by
the Subordinated Debt Trustee] unless and until the [Debtholders] [Subordinated
Debt Trustee] shall have received notice in writing at             to that
                                                       -----------
effect signed by a [designated officer] of the [Credit Party], or by a holder of
Senior Indebtedness or trustee or agent therefor; and prior to the receipt of
any such written notice, the [Debtholders] [Subordinated Debt Trustee] shall be
entitled to assume that no such facts exist[; provided, however, that if the
Subordinated Debt Trustee shall not have received the notice provided for in
this Section 2.06 at least two Business Days prior to the date upon which by the
terms of this [Subordinated Debt Agreement] any moneys shall become payable for
any purpose (including, without limitation, the payment of the principal of or
interest on any Subordinated Debt Instrument), then, regardless of anything
herein to the contrary, the Subordinated Debt Trustee shall have full power and
authority to receive any moneys from the [Credit Party] and to apply the same to
the purpose for which they were received, and shall not be affected by any
notice to the contrary which may be received by it on or after such prior
date]./2/ Nothing contained in this Section 2.06 shall limit the right of the
holders of Senior Indebtedness to recover payments as contemplated by Section
2.03. The Subordinated Debt Trustee shall be entitled to rely on the delivery to
it of a written notice by a Person representing himself or itself to be a holder
of any Senior Indebtedness (or a trustee on behalf of, or other representative
of, such holder) to establish that such notice shall been given by a holder of
such Senior Indebtedness or a trustee or representative on behalf of any such
holder.

          In the event that [any Debtholder] [the Subordinated Debt Trustee]
determines in good faith that any evidence is required with respect to the right
of any Person as a holder of Senior Indebtedness to participate in any payment
or distribution pursuant to this Article Two, [such Debtholder] [the
Subordinated Debt Trustee] may request such Person to furnish evidence to the
reasonable satisfaction of [such Debtholder] [the Subordinated Debt Trustee] as
to the amount of Senior Indebtedness held by such Person, the extent to which
such Person is entitled to participate in such payment or distribution and any
other facts pertinent to the rights of such Person under this Article Two, and
if such evidence is not furnished, [such Debtholder] [the Subordinated Debt
Trustee] may defer any payment to such Person pending judicial determination as
to the right of such Person to receive such payment.

Agent.

          Upon any payment or distribution of assets or securities referred to
in this Article Two, the [Subordinated Debt Trustee and the] holders of the
Subordinated Debt Instruments shall be entitled to rely upon any order or decree
made by any court of competent jurisdiction in which bankruptcy, dissolution,
winding-up, liquidation or reorganization proceedings are pending, or upon a
certificate of the receiver, trustee in bankruptcy, liquidating trustee, agent
or other person making such payment or distribution, delivered to [the

to enforce subordination as provided herein shall at any time in any way be
prejudiced or impaired by any act or failure to act on the part of the [Credit
Party] or by any act or failure to act, in good faith, by any such holder, or by
any noncompliance by the [Credit Party] with the terms of this [Subordinated
Debt Agreement], regardless of any knowledge thereof which any such holder may
have or otherwise be charged with. The provisions of this Article Two are
intended to be for the benefit of, and shall be enforceable directly by, the
holders of Senior Indebtedness.

          Section 2.09. This Article Not To Prevent Events of Default.

          The failure to make a payment on account of principal of or interest
on the Subordinated Debt Instruments by reason of any provision of this Article
Two shall not be construed as preventing the occurrence of an Event of Default
specified in [payment default Sections].

of or notice to [the Subordinated Debt Trustee or] the holders of the
Subordinated Debt Instruments, without incurring responsibility to the holders
of the Subordinated Debt Instruments and without impairing or releasing the
subordination provided in this Article Two or the obligations hereunder of the
holders of the Subordinated Debt Instruments to the holders of Senior
Indebtedness, do any one or more of the following: (a) change the manner, place
or terms of payment or extend the time of payment of, or renew or alter, Senior

          The Subordinated Debt Trustee shall be entitled to all the rights set
forth in this Article Two with respect to any Senior Indebtedness which may at
any time be held by it in its individual or any other capacity to the same
extent as any other holder of Senior Indebtedness, and nothing in this
[Subordinated Debt Agreement] shall deprive the Subordinated Debt Trustee of any
of its rights as such holder.

holders if the Subordinated Debt Trustee shall in good faith mistakenly pay over
or distribute to holders of Subordinated Debt Instruments or to the [Credit
Party] or to any other person cash, property or securities to which any holder
of Senior Indebtedness shall be entitled by virtue of this Article Two or
otherwise.

balance of its Subordinated Debt Instruments in the form required in those
proceedings.

          Section 2.14. Subordinated Debt Trustee's Compensation Not Prejudiced.
