            (b) Global Securities. The Initial Securities are being offered and
sold by the Issuers to the Purchasers pursuant to the Purchase Agreements.

            Initial Securities offered and sold to the Purchasers, as provided

Global Security in global form without interest coupons substantially in the
form of Exhibit A hereto, with such applicable legends as are set forth in
Exhibit A hereto, except as otherwise permitted herein (the "IAI Global
Security"). On the Issue Date a similar Global Security, (the "144A Global
Security" and, together with the IAI Global Security, the "U.S. Global
Securities") in global form shall also be issued to accommodate offers and sales
of Securities in reliance on Rule 144A. The U.S. Global Securities shall be
deposited initially with the Book-Entry Depositary pursuant to the terms of the
Depositary Agreement, duly executed by the Issuers and authenticated by the
Trustee as hereinafter provided. The aggregate principal amount of each U.S.
Global Security may from time to time be increased or decreased by adjustments
made by annotation or endorsement thereon by the Trustee on behalf of the
Issuers (or by the issue of a further U.S. Global Security of the same type), in
connection with a corresponding decrease or increase in the aggregate principal
amount of the other U.S. Global Security or the Regulation S Global Security or
in consequence of the issue of Definitive Securities or additional U.S.
Securities, as hereinafter provided. The U.S. Global Securities and all other
Initial Securities evidencing the debt, or any portion of the debt, initially
evidenced by such U.S. Global Securities, other than Securities transferred or
exchanged upon certification as provided in Section 2.14(a)(i)(1), (2) or (6),
shall collectively be referred to herein as the "U.S. Securities".

            Initial Securities offered and sold in reliance on Regulation S as
provided in the Purchase Agreements, shall be issued initially in the form of a
single Global Security in global form without interest coupons substantially in
the form of Exhibit A hereto, with such applicable legends as are set forth in
Exhibit A hereto, except as otherwise permitted herein, which shall be deposited
initially with the Book-Entry Depositary pursuant to the terms of the Debenture
Depositary Agreement, duly executed by the Issuers and authenticated by the
Trustee as hereinafter provided. Such Global Security shall be referred to
herein as the "Regulation S Global Security". The aggregate principal amount of
the Regulation S Global Security may from time to time be increased or decreased
by adjustments made by annotation or endorsement thereon by the Trustee on
behalf of the Issuers (or by the issue of a further Regulation S Global
Security), in connection with a corresponding decrease or increase in the
aggregate principal amount of a U.S. Global Security or in consequence of the
issue of Definitive Securities or additional Regulation S Securities, as
hereinafter provided. The Regulation S Global Security and all other Initial
Securities that are not U.S. Global Securities shall collectively be referred to
herein as the "Regulation S Securities".

            SECTION 2.02 Execution and Authentication. One or more Officers
shall sign the Securities for the Issuers by manual or facsimile signature.

            If an Officer whose signature is on a Security no longer holds that

valid nevertheless.


                                      -25-


            A Security shall not be valid until an authorized officer of the
Trustee manually signs the certificate of authentication on the Security. The
signature shall be conclusive evidence that the Security has been authenticated
under this Indenture.

            The Trustee shall authenticate and make available for delivery (1)
Initial Securities for original issue in an aggregate principal amount at
maturity of $53,133,016, and (2) Exchange Securities for issue only in a
Registered Exchange Offer, pursuant to the Exchange and Registration Rights
Agreement for Initial Securities for a like principal amount of Initial
Securities exchanged pursuant thereto, in each case upon a written order of the
Issuers signed by one Officer thereof. Such order shall specify the amount of
the Securities to be authenticated, the date on which the original issue of
Securities is to be authenticated, whether the Securities are to be Initial
Securities or Exchange Securities whether the Securities shall bear the Private
Placement Legend, or such other information as the Trustee may reasonably
request. The aggregate principal amount at maturity of Securities outstanding at
any time may not exceed $53,133,016 except as provided in Section 2.07.

            The Trustee may appoint an authenticating agent reasonably
acceptable to the Issuers to authenticate the Securities. Any such appointment
shall be evidenced by an instrument signed by an authorized officer of the
Trustee, a copy of which shall be furnished to the Issuers, and the Trustee
shall notify the Holders of the name and address of any agent not a party to
this Indenture. Unless limited by the terms of such appointment, an
authenticating agent may authenticate Securities whenever the Trustee may do so.
Each reference in this Indenture to authentication by the Trustee includes
authentication by such agent. An authenticating agent has the same rights as any
Registrar, Paying Agent or agent for service of notices and demands.

            SECTION 2.03 Registrar and Paying Agent. The Issuers shall maintain
an office or agency where Securities may be presented for registration of
transfer or for exchange (the "Registrar") and an office or agency where
Securities may be presented for payment (the "Paying Agent"). The Registrar
shall keep a register of the Securities and of their transfer and exchange. The
Issuers may have one or more co-registrars and one or more additional paying
agents. The term "Paying Agent" includes any additional paying agent.

            The Issuers shall enter into an appropriate agency agreement with
any Registrar, Paying Agent or co-registrar not a party to this Indenture, which
shall incorporate the terms of the TIA. The agreement shall implement the
provisions of this Indenture that relate to such agent. The Issuers shall notify
the Trustee of the name and address of any such agent. The Issuers may remove
any Paying Agent, Registrar or co-registrar without prior notice to any Holder.
If the Issuers fail to maintain a Registrar or Paying Agent, the Trustee shall
act as such and shall be entitled to appropriate compensation therefor pursuant
to Section 7.07.

            The Issuers initially appoint the Trustee as Registrar and Paying
Agent in connection with the Securities.

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


                                      -26-


            The Issuers may remove any Registrar or Paying Agent upon written
notice to such Registrar or Paying Agent and to the Trustee; provided, however,
that no such removal shall become effective until (1) acceptance of an
appointment by a successor as evidenced by an appropriate agreement entered into
by the Issuers and such successor Registrar or Paying Agent, as the case may be,
and delivered to the Trustee or (2) notification to the Trustee that the Trustee
shall serve as Registrar or Paying Agent until the appointment of a successor in
accordance with clause (1) above and shall otherwise comply with TIA ss.312(a).
The Registrar or Paying Agent may resign at any time upon written notice.

            The Paying Agent shall comply with all withholding tax, information
reporting and backup withholding tax requirements under the United States
Internal Revenue Code of 1986, as amended (the "Code"), and the Treasury
Regulations issued thereunder in respect of any payment on, or in respect of,
the Securities (including, without limitation, furnishing to the Holders and
collecting Internal Revenue Service ("IRS") Forms 1001, 4224, W-8 or W-9 (or any
successor forms), as the case may be, and filing IRS Forms 1042 and 1042-S with
respect thereto). As promptly as possible after the payment of any withholding
tax, the Paying Agent shall deliver to each Holder appropriate documentation
showing the payment thereof, together with such additional documentary evidence
as such Holders may reasonably request from time to time.

            SECTION 2.04 Paying Agent to Hold Money in Trust. Prior to 10:00
A.M., New York City time, on each due date of the principal, interest and
Additional Amounts, if any, on any Security, the Issuers shall deposit with the
Paying Agent a sum sufficient to pay such principal, interest and Additional
Amounts, if any, then so becoming due. The Issuers shall require each Paying
Agent (other than the Trustee) to agree in writing that the Paying Agent shall
hold in trust for the benefit of Securityholders or the Trustee all money held
by the Paying Agent for the payment of principal of or interest on the
Securities and shall notify the Trustee of any default by the Issuers in making
any such payment. The Issuers at any time may require a Paying Agent to pay all
money held by it to the Trustee and to account for any funds disbursed by the
Paying Agent. Upon complying with this Section, the Paying Agent shall have no
further liability for the money delivered to the Trustee.

            Any money deposited with any Paying Agent in trust for the payment
of principal, interest or Additional Amounts, if any, on any Security and
remaining unclaimed for two years after such principal and interest has become
due and payable shall be paid to the relevant Issuer at its request; and the
Securityholders shall thereafter, as unsecured general creditors, look only to
the Issuers for payment thereof, and all liability of the Paying Agent with
respect to such money shall thereupon cease.

            SECTION 2.05 Securityholder 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 Securityholders and shall otherwise comply with
TIA ss.312(a). If the Trustee is not the Registrar, the Issuers shall furnish,
or cause the Registrar to 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 Securityholders.


                                      -27-


            SECTION 2.06 Transfer and Exchange. The Securities shall be issued
in registered form and the transfer of the Securities shall be registerable only
upon the surrender of a Security for registration of transfer. When a Security
is presented to the Registrar or a co-registrar with a request to register a
transfer, the Registrar shall register the transfer as requested if its
requirements therefor are met. When Securities are presented to the Registrar or
a co-registrar with a request to exchange them for an equal principal amount of
Securities of other denominations, the Registrar shall make the exchange as
requested if its requirements therefor are met. To permit registration of
transfers and exchanges, the Issuers shall execute and the Trustee shall
authenticate Securities at the Registrar's or co-registrar's request. The
Issuers may require payment by the Holder of a sum sufficient to pay all taxes,
assessments or other governmental charges in connection with any transfer or
exchange pursuant to this Section. The Issuers shall not be required to make and
the Registrar need not register transfers or exchanges of Securities selected
for redemption (except, in the case of Securities to be redeemed in part, the
portion thereof not to be redeemed) or any Securities for a period of 15 days
before a selection of Securities to be redeemed.

            Prior to the due presentation for registration of transfer of any
Security, the Issuers, the Company, the Trustee, the Paying Agent, the Registrar
or any co-registrar may deem and treat the Person in whose name a Security is
registered as the absolute owner of such Security for the purpose of receiving
payment of principal of and, subject to the record date provisions of this
Indenture, interest, if any, on such Security and for all other purposes
whatsoever, whether or not such Security is overdue, and none of the Issuers,
the Company, the Trustee, the Paying Agent, the Registrar or any co-registrar
shall be affected by notice to the contrary.

            The Company may require payment of a sum sufficient to pay all
taxes, assessments or other governmental charges in connection with any transfer
or exchange pursuant to Section 2.06 (other than in respect of the Exchange
Offer, except as otherwise provided in the Registration Rights Agreement).

            All Securities issued upon any registration of transfer or exchange
pursuant to this Section 2.06 will evidence the same debt and will be entitled
to the same benefits under this Indenture as the Securities surrendered upon
such registration of transfer or exchange.

            SECTION 2.07 Replacement Securities. If a mutilated Security is
surrendered to the Registrar or if the Holder of a Security claims that the
Security has been lost, destroyed or wrongfully taken, the Issuers shall issue
and the Trustee shall authenticate a replacement Security if the Trustee's
requirements therefor are met, such that the Holder (i) provides evidence to the
satisfaction of the Issuers or the Trustee within a reasonable time after such
Holder has notice of such loss, destruction or wrongful taking and the Registrar
does not register a transfer prior to receiving such notification, (ii) makes
such a request to the Issuers or the Trustee prior to the Security being
acquired by a bona fide purchaser and (iii) satisfies any other reasonable
requirements of the Trustee. If required by the Trustee or the Issuers, such
Holder shall furnish an indemnity bond sufficient in the judgment of the Trustee
to protect the Issuers, the Trustee, the Paying Agent, the Registrar and any
co-registrar from any loss that any of them may suffer if a Security is
replaced. The Issuers and the Trustee may charge the Holder for their expenses
in replacing a Security. In the event any such mutilated, lost, destroyed or
wrongfully taken Security 


                                      -28-


has become or is about to become due and payable, the Issuers in their
discretion may pay such Security instead of issuing a new Security in
replacement thereof.

            Every replacement Security is an additional obligation of the
Issuers.

            The provisions of this Section 2.07 are exclusive and shall preclude
(to the extent lawful) all other rights and remedies with respect to the
replacement or payment of mutilated, lost, destroyed or wrongfully taken
Securities.

            SECTION 2.08 Outstanding Securities. Securities outstanding at any
time are all Securities authenticated by the Trustee except for those canceled
by it, those delivered to it for cancellation and those described in this
Section as not outstanding. A Security does not cease to be outstanding because
the Issuers or an Affiliate of the Issuers holds the Security.

            If a Security is replaced pursuant to Section 2.07, such replaced
Security ceases to be outstanding unless the Trustee and the Issuers receive
proof satisfactory to them that such replaced Security is held by a bona fide
purchaser.

            If the Paying Agent segregates and holds in trust, in accordance
with this Indenture, on a redemption date or maturity date money sufficient to
pay all principal and interest payable on that date with respect to the
Securities (or portions thereof) to be redeemed or maturing, as the case may be,
and the Paying Agent is not prohibited from paying such money to the
Securityholders on that date pursuant to the terms of this Indenture, then on
and after the date such Securities (or portions thereof) cease to be outstanding
and interest on them ceases to accrue.

            In determining whether the Holders of the required principal amount
of Securities have concurred in any direction, waiver or consent, Securities
owned by the Issuers or any of their Affiliates shall be disregarded, except
that, for the purposes of determining whether the Trustee shall be protected in
relying on any such direction, waiver or consent, only Securities which a Trust
Officer of the Trustee knows or has reason to know are so owned shall be
disregarded.

            SECTION 2.09 Temporary Securities. Until Definitive Securities are
ready for delivery, the Issuers may prepare and the Trustee shall authenticate
temporary Securities. Temporary Securities shall be substantially in the form of
Definitive Securities but may have variations that the Issuers consider
appropriate for temporary Securities. Without unreasonable delay, the Issuers
shall prepare and the Trustee shall authenticate Definitive Securities and
deliver them in exchange for temporary Securities at the office or agency of the
Issuers, without charge to the Holder.

            SECTION 2.10 Cancellation. The Issuers at any time may deliver
Securities to the Trustee for cancellation. The Registrar and the Paying Agent
shall forward to the Trustee any Securities surrendered to the Registrar or
Paying Agent for registration of transfer, exchange, payment or cancellation.
The Trustee and no one else shall cancel all Securities surrendered for
registration of transfer, exchange, payment or cancellation and shall dispose of
canceled Securities in accordance with its customary procedures unless otherwise
directed by written direction of an 


                                      -29-


Officer of the Issuers. The Issuers may not issue new Securities to replace
Securities it has redeemed, paid or delivered to the Trustee for cancellation.
The Trustee shall not authenticate Securities in place of canceled Securities
other than pursuant to the terms of this Indenture.

            SECTION 2.11 Defaulted Interest. If the Issuers default in a payment
of interest on the Securities, the Issuers shall pay the defaulted interest
(plus interest on such defaulted interest to the extent lawful) in any lawful
manner. The Issuers shall pay the defaulted interest to, in the case of
Definitive Securities, the Persons who are Securityholders or, in the case of a
Global Security, to the Holder thereof on a subsequent special record date. The
Issuers shall fix or cause to be fixed any such special record date and payment
date to the reasonable satisfaction of the Trustee and shall promptly mail or
cause to be mailed to each Securityholder a notice that states the special
record date, the payment date and the amount of defaulted interest to be paid.

            The Issuers may make payment of any defaulted interest in any other
lawful manner not inconsistent with the requirements (if applicable) of any
securities exchange on which the Securities may be listed, and upon such notice
as may be required by such exchange, if, after notice given by the Issuers to
the Trustee of the proposed payment pursuant to this paragraph, such manner of
payment shall be deemed practicable by the Trustee.

            SECTION 2.12 CUSIP Numbers. The Issuers in issuing the Securities
may use "CUSIP" numbers (if then generally in use) and, if so, the Trustee shall
use "CUSIP" numbers in notices of redemption or exchange as a convenience to
Holders; provided, however, that any such notice may state that no
representation is made as to the correctness of such numbers either as printed
on the Securities or as contained in any notice of a redemption or exchange and
that reliance may be placed only on the other identification numbers printed on
the Securities, and any such redemption shall not be affected by any defect in
or omission of such numbers. The Issuers will promptly notify the Trustee of any
change in the CUSIP numbers.

            SECTION 2.13 Book-Entry Provisions for Global Securities. (a) Each
Global Security initially shall be registered in the name of The Chase Manhattan
Bank as Book-Entry Depositary ("Book-Entry Depositary") pursuant to the terms of
the Debenture Depositary Agreement. The Book-Entry Depositary will issue one or
more certificateless depositary interests to the Depositary. Upon confirmation
by the Depositary that the Book-Entry Depositary has custody of the Global
Security and upon acceptance by the Depositary of the certificateless depositary
interest pursuant to the applicable letter of representations, the Depositary
will record a beneficial interest in such Global Security. Each Global Security
shall be delivered to the Book-Entry Depositary. Beneficial interests in the
Global Securities may be held indirectly through members of or participants in
("Agent Members") the Depositary (including Cedel and Euroclear in the case of
the Regulation S Global Security).

            Agent Members shall have no rights under this Indenture with respect
to any Global Security held on their behalf by the Depositary, or the Book-Entry
Depositary, or under such Global Security, and the Book-Entry Depositary may be
treated by the Issuers, the Company, the Trustee and any agent of the Issuers,
the Company or the Trustee as the absolute owner of such Global Security for all
purposes whatsoever, except as otherwise provided herein. Notwithstanding the
foregoing, nothing herein shall prevent the Issuers, the Company, the Trustee or


                                      -30-


any agent of the Issuers, the Company or the Trustee from giving effect to any
written certification, proxy or other authorization furnished by the Book-Entry
Depositary or shall impair, as between the Book-Entry Depositary and its Agent
Members, the operation of customary practices governing the exercise of the
rights of a Holder of any Security.

            (b) Transfers of a non-certificated depositary interest in a Global
Security shall be limited to transfers of such non-certificated depositary
interest in a Global Security in whole, but not in part, to the Depositary, its
successors or their respective nominees. Interests of beneficial owners in a
Global Security may be transferred in accordance with the rules and procedures
of the Depositary (and Agent Member, if applicable) and the provisions of
Sections 2.06 and 2.14. Definitive Securities shall be transferred to all
beneficial owners in exchange for their beneficial interests in a Global
Security if (i) the Depositary notifies the Issuers that it is unwilling or
unable to continue as Depositary for such Global Security or the Depositary
ceases to be a clearing agency registered under the Exchange Act, at a time when
the Depositary is required to be so registered in order to act as Depositary,
and in each case a successor depositary is not appointed by the Issuers within
90 days of such notice, or (ii) Book-Entry Depositary notifies the Issuers that
it is unwilling or unable to continue as Book-Entry Depositary and a successor
book-entry depositary is not appointed by the Issuers within 90 days of such
notice or (iii) an Event of Default has occurred and is continuing and the
Registrar has received a request from the Depositary or the Trustee to permit
such transfers.

            (c) Any Initial Securities which are presented to the Registrar for
exchange pursuant to the Exchange Offer shall be exchanged for Exchange
Securities of equal principal amount upon surrender to the Registrar of the
Initial Securities to be exchanged; provided, however, that the Initial
Securities so surrendered for exchange shall be duly endorsed and accompanied by
a letter of transmittal or written instrument of transfer in form satisfactory
to the Issuers, the Trustee and the Registrar duly executed by the Holder
thereof or his attorney who shall be duly authorized in writing to execute such
document. Whenever any Initial Securities are so surrendered for exchange, the
Issuers shall execute, and the Trustee shall authenticate and deliver to the
Holder the same aggregate principal amount of Exchange Securities as those
Initial Securities that have been surrendered.

            (d) The registered holder of a Global Security may grant proxies and
otherwise authorize any Person, including Agent Members and Persons that may
hold interests through Agent Members, to take any action which a Holder is
entitled to take under this Indenture or the Securities. Whenever all of a
Global Security is exchanged for one or more Definitive Securities, it shall be
surrendered by the Holder thereof to the Trustee for cancellation. Whenever a
part of a Global Security is exchanged for one or more Definitive Securities the
Global Security shall be surrendered by the Holder thereof to the Trustee who
shall cause an adjustment to be made to Schedule A of such Global Security such
that the principal amount of such Global Security will be equal to the portion
of such Global Security not exchanged and shall thereafter return such Global
Security to such Holder. All Definitive Securities issued in exchange for a
Global Security or any portion thereof shall be registered in such names as the
Depositary, after conferring with the Registrar, shall instruct the Trustee.
Every Security authenticated and delivered in exchange for or in lieu of a
Global Security, or any portion thereof, pursuant to Section 2.14(a), 2.14(b) or
otherwise, shall be authenticated and delivered in the form of, and shall be, a
Global Security or a 


                                      -31-


Definitive Security. A Global Security may not be exchanged for a Definitive
Security other than as provided in this Section 2.13(b).

            (e) Holders of Initial Securities (or holders of interests therein)
and prospective purchasers designated by such Holders (or holders of interests
therein) will have the right to obtain from the Issuers or the Company upon
request by such Holders (or holders of interests therein) or prospective
purchasers, during any period in which the Issuers or the Company is not subject
to Section 13 or 15(d) of the Exchange Act, or is exempt from reporting pursuant
to 12g3-2(b) under the Exchange Act, the information required by paragraph
d(4)(i) of Rule 144A in connection with any transfer or proposed transfer of
such Securities.

            SECTION 2.14 Special Transfer Provisions. (a) Provisions Applicable
Solely to Initial Securities. The following procedures and restrictions shall
not apply with respect to Initial Securities transferred or exchanged for the
account of a Person who is not an Affiliate of the Issuers at the time of the
transfer or exchange and has not been an Affiliate during the preceding three
months, provided a period of at least two years has elapsed since the later of
the date the Initial Securities were acquired from the Issuers or from an
Affiliate of the Issuers.

            (i) Notwithstanding any other provisions of this Indenture or the
      Securities, transfers and exchanges of interests in an Initial Global
      Security of the kinds described in clauses (1) through (5) below and
      exchanges of interests in Initial Global Securities or of other Initial
      Securities as described in clauses (6) through (9) below, shall be made
      only in accordance with this Section 2.14(a), and all transfers of an
      interest in the Regulation S Global Security shall comply with clause (10)
      below.

                  (1) Transfers of U.S. Global Security to Regulation S Global
            Security During the Restricted Period. If the holder of a beneficial
            interest in a U.S. Global Security wishes at any time during the
            Restricted Period to transfer such interest to a Person who wishes
            to take delivery thereof in the form of a beneficial interest in the
            Regulation S Global Security, such transfer may be effected, subject
            to the rules and procedures of the Depositary, the Euroclear
            Operator and Cedel, to the extent applicable (the "Applicable
            Procedures"), only in accordance with the provisions of this Section
            2.14(a)(i)(1). Upon receipt by the Book-Entry Depositary of a
            certificate in substantially the form set forth in Exhibit C given
            by the transferor, the Book-Entry Depositary shall present the
            Initial Global Securities to the Trustee on behalf of the Issuers to
            reduce the principal amount of the U.S. Global Security and to
            increase the principal amount of the Regulation S Global Security,
            by the principal amount of the beneficial interest in the U.S.
            Global Security to be so transferred, by annotation thereon.

                  (2) Transfers of U.S. Global Security to Regulation S Global
            Security After the Expiration of the Restricted Period. If the
            holder of a beneficial interest in the U.S. Global Security wishes
            at any time after the expiration of the Restricted Period to
            transfer such interest to a Person who wishes to take delivery
            thereof in the form of a beneficial interest in the Regulation S
            Global Security, such transfer may be effected, subject to the
            Applicable Procedures, only in accordance with this 


                                      -32-


            Section 2.14(a)(i)(2). Upon receipt by the Book-Entry Depositary of
            a certificate in substantially the form set forth in Exhibit D given
            by the transferor, the Book-Entry Depositary shall present the
            Initial Global Securities to the Trustee on behalf of the Issuers to
            reduce the principal amount of the U.S. Global Security, and to
            increase the principal amount of the Regulation S Global Security,
            by the principal amount of the beneficial interest in the U.S.
            Global Security to be so transferred, by annotation thereon.

                  (3) Transfers of Regulation S Global Security to U.S. Global
            Security. If the holder of a beneficial interest in the Regulation S
            Global Security wishes at any time to transfer such interest to a
            Person who wishes to take delivery thereof in the form of a
            beneficial interest in a U.S. Global Security, such transfer may be
            effected, subject to the Applicable Procedures, only in accordance
            with this Section 2.14(a)(i)(3). Upon compliance with the Applicable
            Provisions, the Book-Entry Depositary shall present the Initial
            Global Securities to the Trustee on behalf of the Issuers to reduce
            the principal amount of the Regulation S Global Security, and to
            increase the principal amount of the applicable U.S. Global
            Security, by the principal amount of the beneficial interest in the
            Regulation S Global Security to be so transferred, by annotation
            thereon; provided, however, that, prior to the expiration of the
            Restricted Period, such transfer shall be made only if, in addition,
            the Book Entry Depositary has received a certificate in
            substantially the form set forth in Exhibit E given by the
            transferor (and, in the case of a transfer to the IAI Global
            Security, a signed letter from the transferee in substantially the
            form set forth in Annex A thereto)

                  (4) Transfers of IAI Global Security to Rule 144A Global
            Security. If the holder of a beneficial interest in the IAI Global
            Security (whether during the Restricted Period or after the
            expiration of the Restricted Period) wishes to transfer such
            interest to a Person who wishes to take delivery thereof in the form
            of a beneficial interest in the Rule 144A Global Security, such
            transfer may be effected, subject to the Applicable Procedures, only
            in accordance with this Section 2.14(a)(i)(4). Upon receipt by the
            Book-Entry Depositary of a certificate in substantially the form set
            forth in Exhibit F given by the transferor, the Book-Entry
            Depositary shall present the Initial Global Securities to the
            Trustee on behalf of the Issuers to reduce the principal amount of
            the IAI Global Security from which such transfer is to be made, and
            to increase the principal amount of the Rule 144A Global Security,
            by the principal amount of the beneficial interest in the IAI Global
            Security to be so transferred, by annotation thereon.

                  (5) Transfers of Rule 144A Global Security to IAI Global
            Security. If the holder of a beneficial interest in the Rule 144A
            Global Security (whether during the Restricted Period or after the
            expiration of the Restricted Period) wishes to transfer such
            interest to a Person who wishes to take delivery thereof in the form
            of a beneficial interest in the IAI Global Security, such transfer
            may be effected, subject to the Applicable Procedures, only in
            accordance with this Section 2.14(a)(i)(5). Upon receipt by the
            Book-Entry Depositary of a certificate 


                                      -33-


            in substantially the form set forth in Exhibit G given by the
            transferor and a signed letter from the transferee substantially in
            the form set forth in Annex A thereto, the Book-Entry Depositary on
            behalf of the Issuers shall present the Initial Global Securities to
            the Trustee to reduce the principal amount of the Rule 144A Global
            Security from which such transfer is to be made, and to increase the
            principal amount of the IAI Global Security, by the principal amount
            of the beneficial interest in the Rule 144A Global Security to be so
            transferred, by annotation thereon.

                  (6) Exchanges of U.S. Global Security for Regulation S Global
            Security. If the holder of a beneficial interest in a U.S. Global
            Security wishes at any time to exchange such interest for a
            beneficial interest in the Regulation S Global Security, such
            exchange may be effected, subject to the Applicable Procedures, only
            in accordance with the provisions of this Section 2.14(a)(i)(6).
            Upon receipt by the Book-Entry Depositary of a certificate in
            substantially the form set forth in Exhibit H, given by the holder
            of the beneficial interest, the Book-Entry Depositary shall present
            the Initial Global Securities to the Trustee on behalf of the
            Issuers to reduce the principal amount of such U.S. Global Security,
            and to increase the principal amount of the Regulation S Global
            Security, by the principal amount of the beneficial interest in such
            U.S. Global Security to be so exchanged, by annotation thereon.

                  (7) Exchanges of Regulation S Global Security for U.S. Global
            Security. If the holder of a beneficial interest in the Regulation S
            Global Security wishes at any time to exchange such interest for a
            beneficial interest in a U.S. Global Security, such exchange may be
            effected, subject to the Applicable Procedures, only in accordance
            with the provisions of this Section 2.14(a)(i)(7). Upon receipt by
            the Book-Entry Depositary of a certificate in substantially the form
            set forth in Exhibit I, given by the holder of the beneficial
            interest, the Book-Entry Depositary shall present the Initial Global
            Securities to the Trustee on behalf of the Issuers or its agent to
            reduce the principal amount of the Regulation S Global Security, and
            to increase the principal amount of the applicable U.S. Global
            Security, by the principal amount of the beneficial interest in the
            Regulation S Global Security to be so exchanged, by annotation
            thereon.

                  (8) Exchanges of U.S. Global Security for another U.S. Global
            Security. If the holder of a beneficial interest in a U.S. Global
            Security wishes at any time to exchange such interest for a
            beneficial interest in the other U.S. Global Security, such exchange
            may be effected, subject to the Applicable Procedures, only in
            accordance with the provisions of this Section 2.14(a)(i)(8). Upon
            receipt by the Book-Entry Depositary of a certificate in
            substantially the form set forth in Exhibit J given by the holder of
            the beneficial interest (and including, in the case of an exchange
            into the IAI Global Security, a signed letter substantially in the
            form set forth in Annex A thereto), the Book-Entry Depositary shall
            present the Initial Global Securities to the Trustee on behalf of
            the Issuers to reduce the principal amount of the U.S. Global
            Security to be exchanged, and to increase the principal 


                                      -34-


            amount of the other U.S. Global Security, by the principal amount of
            the beneficial interest in the U.S. Global Security to be so
            exchanged, by annotation thereon.

                  (9) Other Exchanges. In the event that an Initial Global
            Security or any portion thereof is exchanged for Initial Securities
            in definitive form pursuant to Section 2.13(b) hereof, such
            Definitive Securities may in turn be exchanged (on transfer or
            otherwise) for other Definitive Securities and only in accordance
            with such procedures, which shall be substantially consistent with
            the provisions of clauses (1) through (8) above and (10) below)
            (including the certification requirements intended to ensure that
            transfers and exchanges of beneficial interests in an Initial
            Security comply with Rule 144A or Regulation S, as the case may be)
            and any Applicable Procedure as may from time to time be adopted by
            the Issuers and the Registrar.

                  (10) Interests in Regulation S Global Security to be Held
            Through the Euroclear Operator or Cedel. Until the expiration of the
            Restricted Period, interests in the Regulation S Global Security may
            be held only through the Euroclear Operator and Cedel; provided,
            however, that this clause (10) shall not prohibit any transfer in
            accordance with Section 2.14(a)(i)(3).

            (ii) Each Initial Security issued hereunder shall, upon issuance,
      bear the legend set forth on the form of the Security attached hereto as
      Exhibit A and such legend shall not be removed from such Initial Security
      except as provided in the next sentence. The legend required for an
      Initial Security may be removed from an Initial Security if there is
      delivered to the Issuers such satisfactory evidence, which may include an
      opinion of independent counsel licensed to practice law in the State of
      New York, as may be reasonably required by the Issuers, that neither such
      legend nor the restrictions on transfer set forth therein are required to
      ensure that transfers of such Security will not violate the registration
      requirements of the Securities Act. Upon provision of such satisfactory
      evidence, the Trustee, at the direction of the Issuers, shall authenticate
      and deliver in exchange for such Security another Security or Securities
      having an equal aggregate principal amount that does not bear such legend.
      If such a legend required for an Initial Security has been removed from an
      Initial Security as provided above, no other Security issued in exchange
      for all or any part of such Security shall bear such legend, unless the
      Issuers have reasonable cause to believe that such other Security is a
      "restricted security" within the meaning of Rule 144 and instructs the
      Trustee to cause a legend to appear thereon.

            (b) General. By its acceptance of any Security bearing the Private
Placement Legend, each Holder of such a Security acknowledges the restrictions
on transfer of such Security set forth in this Indenture and in the Private
Placement Legend and agrees that it shall transfer such Security only as
provided in this Indenture.

            The Registrar shall retain in accordance with its customary
procedures copies of all letters, notices and other written communications
received pursuant to Section 2.14. The Issuers shall have the right to inspect
and make copies of all such letters, notices or other written 


                                      -35-


communications at any reasonable time upon the giving of reasonable written
notice to the Registrar.

                                   ARTICLE III

                                   Redemption

            SECTION 3.01 Notices to Trustee. If the Issuers elect to redeem
Securities pursuant to paragraph 5 of the Securities, they shall notify the
Trustee in writing of the redemption date, the principal amount of Securities to
be redeemed and the paragraph of the Securities pursuant to which the redemption
will occur.

            The Issuers shall give each notice to the Trustee provided for in
this Section at least 60 days before the redemption date unless the Trustee
consents to a shorter period. Such notice shall be accompanied by an Officers'
Certificate from the Issuers to the effect that such redemption will comply with
the conditions herein. Any such notice may be canceled at any time prior to
notice of such redemption being mailed to any Holder and shall thereby be void
and of no effect.

            SECTION 3.02 Selection of Securities to Be Redeemed. If a partial
redemption is made pursuant to Section 3.07(a) or with the proceeds of a Public
Equity Offering pursuant to Section 3.07(b), the Trustee shall select the
Securities to be redeemed only on a pro rata basis (to the extent practicable)
or by lot, unless such method is otherwise prohibited by applicable legal and
securities exchange requirements, if any. The Trustee shall make the selection
from outstanding Securities not previously called for redemption. The Trustee
may select for redemption portions of the principal of Securities that have
denominations larger than $1. Securities and portions of them the Trustee
selects shall be in amounts of $1 or a whole multiple of $1. Provisions of this
Indenture that apply to Securities called for redemption also apply to portions
of Securities called for redemption. The Trustee shall notify the Issuers
promptly (and, in any event, at least 30 days prior to redemption) of the
Securities or portions of Securities to be redeemed.

            SECTION 3.03 Notice of Redemption. At least 30 days but not more
than 60 days before a date for redemption of Securities, the Issuers shall mail
a notice of redemption by first-class mail to each Holder of Securities to be
redeemed.

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

            (1) the redemption date;

            (2) the redemption price;

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

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


                                      -36-


            (5) if fewer than all the outstanding Securities are to be redeemed,

plus accrued and unpaid interest to the date fixed for such payment if, as a
result of any change in or amendment to the laws, regulations or governmental
policy having the force of law of the Cayman Islands or Thailand (or of any
political subdivision or taxing authority thereof or therein) or any execution
of or amendment to, any treaty or treaties affecting taxation of which the
Cayman Islands or Thailand (or such political subdivision or taxing authority)
is a party, which becomes effective on or after the date of the Indenture (i)
(A) the Issuers are required, or would be required on the next succeeding
Interest Payment Date, to pay Additional Amounts in respect of payments on the
Securities in excess of the 15% withholding requirement as of the Closing Date
as a result of the imposition of Taxes imposed by the Cayman Islands or Thailand
(or any political subdivision or taxing authority of either jurisdiction); (B)
the Company is, or on the next succeeding interest payment date would be, unable
for reasons outside of its control, to procure payment by the Issuers and, with
respect to any payment due, or to become due, under the Securities or the
Guaranty, the Company is required, or would be required on the next succeeding
Interest Payment Date, to pay Additional Amounts as a result of the imposition
of Taxes by the Cayman Islands or Thailand or (C) with respect to any payment to
an Issuer to enable an Issuer to make any payments under the Securities, the
Company or NSM Cayman is, or on the next Interest Payment Date would be,
required to deduct or withhold Taxes imposed by the Cayman Islands or Thailand

(ii) the payment of such Additional Amounts cannot be avoided by the use of any
reasonable measures available to the Issuers or the Company that do not require
undue effort or costs (including, without limitation, the Company making
payments directly to holders under the Guaranty). In addition, the Issuers or
the Company, as the case may be, will also pay to holders on the redemption date
any Additional Amounts which would otherwise be payable; 


                                      -38-


provided, however, that no such notice of redemption shall be given earlier than
90 days prior to the earliest date on which the Issuers or the Company, as the
case may be, would be obligated to pay such Additional Amounts if a payment in
respect of the Securities or a Guaranty were then due.

            Prior to the publication of the notice of redemption in accordance
with the foregoing, the Issuers or the Company shall deliver to the Trustee an
Officers' Certificate stating that (x) the Issuers are or the Company is
entitled to effect such redemption based on a written opinion of counsel or
written advice of a nationally recognized independent tax counsel, such opinion
or advice being reasonably acceptable to the Trustee, that the condition
referred to in either of subclauses (A) or (B) or (C) of clause (i) of the
immediately preceding paragraph is satisfied as a result of such change,
amendment or executed or amended treaty and (y) the condition described in (ii)
of the immediately preceding paragraph is satisfied. Such notice, once delivered
by the Issuers or the Company to the Trustee, will be irrevocable.

            (c) Notwithstanding the foregoing, neither the Issuers nor the
Company may incur any Indebtedness if such Indebtedness is expressly subordinate
in right of payment to any Specified Senior Indebtedness unless such
Indebtedness is expressly subordinated in right of payment to the Securities to
at least the same extent as such Specified Senior Indebtedness.

            (d) Notwithstanding the foregoing, neither the Company nor the
Issuers shall Incur any Indebtedness pursuant to the foregoing paragraph (b) if

            (i) the payment of any dividend or distribution within 60 days after
      the date of declaration thereof, if at such date of declaration such
      payment would be permitted by the provisions of paragraph (a) of this
      section and such payment will be deemed to have been paid on (and included
      in the calculation of the amount of Restricted Payments) such date of
      declaration for purposes of the calculation required by paragraph (a) of
      this section;

            (ii) the repurchase, redemption or other acquisition or retirement
      of any shares of Capital Stock of the Company in exchange for (including

      fractional shares or scrip), or out of the Net Cash Proceeds of a
      substantially concurrent issue and sale for cash (other than to a
      Restricted Subsidiary) of other Capital Stock (other than Disqualified

      substantially concurrent issuance and sale for cash (other than to any
      Restricted Subsidiary of the Company) of any Capital Stock (other than
      Disqualified Stock) of the Company; provided that the Net Cash Proceeds
      from the issuance of such Capital Stock (other than Disqualified Stock)
      are excluded from clauses (3)(B) and (3)(C) of paragraph (a) of this
      section, and such repurchases, redemptions, defeasances, retirements or
      acquisitions shall be excluded from the calculation of the amount of
      Restricted Payments; and

            (iv) the repurchase, redemption, defeasance, retirement,
      refinancing, acquisition for value or payment of principal of any
      Subordinated Indebtedness (other than Disqualified Stock) or Pari Passu

      Indebtedness of the Company; provided that any such new Subordinated
      Indebtedness (1) shall be in a principal amount that does not exceed the
      principal amount so refinanced (or, if the Subordinated Indebtedness so
      refinanced provides for an amount less than the principal amount thereof
      to be due and payable upon a declaration or acceleration thereof, then
      such lesser amount as of the date of determination), plus the amount of
      any premium required to be paid in connection with such refinancing
      pursuant to the terms of such refinanced Indebtedness and any reasonable
      out-of-pocket expenses of the Company incurred in connection with such
      refinancing; (2) has an Average Life to Stated Maturity greater than the

            For purposes of this Section, if the Board of Directors designates a
Restricted Subsidiary as an Unrestricted Subsidiary, or a Restricted Subsidiary
is deemed to be so 


                                      -43-


designated, a "Restricted Payment" shall be deemed to have been made in an
amount equal to the fair value of the Investment of the Company and its other
Restricted Subsidiaries in such Restricted Subsidiary as determined by the Board
of Directors with the concurrence of a majority of the Independent Directors
(there being at least one Independent Director), whose good-faith determination
shall be conclusive. If a particular Restricted Payment involves a noncash
payment, including a distribution of assets, then such Restricted Payment shall
be deemed to be in an amount equal to the fair market value of the noncash
portion of such Restricted Payment as determined by the Board of Directors,
whose good-faith determination shall be conclusive.

            SECTION 4.05 Limitation on Liens. Neither the Issuers nor the
Company will affirm or permit to exist any Lien of any kind securing any Pari
Passu Indebtedness or Subordinated Indebtedness of the Issuers or the Company
(including any assumption, guarantee or other liability with respect thereto by
any Subsidiary) upon any property or assets (including any intercompany notes)
of the Issuers or the Company or any Subsidiary owned on the date of the
Indentures or acquired after the date of the Indentures, or any income or
profits therefrom, other than Permitted Liens.

            SECTION 4.06 Limitation on Sales of Assets and Subsidiary Stock. (a)
The Company shall not, and shall not permit either of the Issuers or any
Restricted Subsidiary to, make any Asset Disposition unless (i) the Company, the
Issuers or such Restricted Subsidiary receives consideration at the time of such
Asset Disposition at least equal to the fair market value, as determined in good
faith by the Company's Board of Directors (including as to the value of all
non-cash consideration), of the shares and assets subject to such Asset
Disposition, (ii) at least 80% of the consideration thereof received by the
Company, the Issuers or such Restricted Subsidiary is in the form of cash or
Cash Equivalents, (iii) an amount equal to 100% of the Net Available Cash from
such Asset Disposition is applied: (A) if at the time of the Asset Disposition
the Company has not yet achieved Profitable Operations, pro rata to a mandatory
offer by the Issuers and the Company to purchase Securities at 101% of the
Accreted Value thereof on the date of purchase, plus accrued and unpaid interest
and Additional Amounts, if any, thereon, and the repayment of principal and
accrued and unpaid interest, if any, under the Bank Credit Facility and (B) if
at the time of the Asset Disposition the Company has achieved Profitable
Operations, at the Company's option either to (1) the investment in or
acquisition of Additional Assets within 365 days from the later of such Asset
Disposition and the receipt of such Net Available Cash or (2) pro rata to a
mandatory offer by the Issuers and the Company to purchase Securities at 101% of
the Accreted Value thereof on the date of purchase plus accrued and unpaid
interest and Additional Amounts, if any, thereon, and the repayment of principal
and accrued and unpaid interest, if any, under the Bank Credit Facility;
provided that the Issuers and the Company shall be required to purchase
Indebtedness pursuant to clause (2) to the extent of the balance of such Net
Available Cash after application in accordance with clause (1). The Issuers
shall not be required to make an offer to purchase Securities pursuant to this
covenant if the Net Available Cash available therefor (after application of the
proceeds as provided in clause (A)) is less than U.S.$10 million for any
particular Asset Disposition (which lesser amounts shall be carried forward for
purposes of determining whether an offer is required with respect to the Net
Available Cash from any subsequent Asset Disposition). Notwithstanding the
foregoing provisions, Net Available Cash shall not be required to be applied in
accordance herewith to the extent that the aggregate 


                                      -44-


Net Available Cash from all Asset Dispositions which are not applied in
accordance with this covenant at any time does not exceed U.S.$10 million.

            Notwithstanding the foregoing, to the extent the Senior Note
Indenture and the Senior Subordinated Note Indenture limits the repurchase of
Securities, the Issuers shall not be required to make an offer hereunder for the
repurchase of Securities.

            For the purposes of this Section 4.06, the following will be deemed
to be cash: (x) the assumption by transferee of Senior Indebtedness of the
Company, the Issuers or any Restricted Subsidiary and the release of the
Company, the Issuers or any Restricted Subsidiary from all liability on such
Senior Indebtedness in connection with such Asset Disposition and (y) securities
received by the Company, the Issuers or any Restricted Subsidiary from the
transferee that are promptly (and in any event within 60 days) converted by the
Company, the Issuers or such Restricted Subsidiary into cash.

            (b) In the event of an Asset Disposition that requires the purchase
of Securities pursuant to Section 4.06(a)(iii)(A) or (B)(2), the Issuers shall
be required to purchase Securities tendered by the Holders pursuant to an offer
by the Company for the Securities (the "Offer") at a purchase price (the
"Purchase Price") of 101% of the Accreted Value thereof on the date of purchase,
plus accrued and unpaid interest and Additional Amounts, if any, thereon to the
Purchase Date (as defined below) in accordance with the procedures (including
prorationing in the event of oversubscription) set forth in Section 4.06(c).

            (c) (1) Promptly, and in any event within 10 days after the Issuers
become obligated to make an Offer, the Issuers shall be obligated to deliver to
the Trustee and send, by first-class mail to each Holder, a written notice
stating that the Holder may elect to have his Securities purchased by the
Issuers either in whole or in part (subject to prorationing as hereinafter
described in the event the Offer is oversubscribed) in integral multiples of $1
of principal amount, at the Purchase Price. The notice shall specify a purchase
date not less than 30 days nor more than 60 days after the date of such notice
(the "Purchase Date") and shall contain such information concerning the business
of the Issuers which the Issuers in good faith believes will enable such Holders
to make an informed decision (which at a minimum shall include (i) the most
recently filed annual report (including audited consolidated financial
statements) of the Issuers and any other information provided by the Issuers to
its public shareholders generally on an annual basis, the most recently filed
Reports, and any current reports of the Issuers filed subsequent to such Report,
other than current reports describing Asset Dispositions otherwise described in
the offering materials (or corresponding successor reports), (ii) a description
of material developments in the Issuers' business subsequent to the date of the
latest of such reports, and (iii) if material, appropriate pro forma financial
information) and all instructions and materials necessary to tender Securities
pursuant to the Offer, together with the address referred to in clause (3).

            (2) Not later than the date upon which written notice of an Offer is
delivered to the Trustee as provided above, the Issuers shall deliver to the
Trustee an Officers' Certificate as to (i) the amount of the Offer (the "Offer
Amount"), (ii) the allocation of the Net Available Cash from the Asset
Dispositions pursuant to which such Offer is being made and (iii) the compliance


                                      -45-


of such allocation with the provisions of Section 4.06(a). On such date, the
Issuers shall also irrevocably deposit with the Trustee or with the Paying Agent
an amount equal to the Offer Amount to be invested at the written direction of
the Issuers in Cash Equivalents and to be held for payment in accordance with
the provisions of this Section. Upon the expiration of the period for which the
Offer remains open (the "Offer Period"), the Issuers shall deliver to the
Trustee for cancellation the Securities or portions thereof that have been
properly tendered to and are to be accepted by the Issuers. The Trustee (or the
Paying Agent, if not the Trustee) shall, on the Purchase Date, mail or deliver
payment to each tendering Holder in the amount of the purchase price. In the
event that the aggregate purchase price of the Securities delivered by the
Issuers to the Trustee is less than the Offer Amount, the Trustee shall deliver
the excess to the Issuers promptly after the expiration of the Offer Period for
application in accordance with this Section.

            (3) Holders electing to have a Security purchased shall be required
to surrender the Security, with an appropriate form duly completed, to the
Issuers at the address specified in the notice at least three Business Days
prior to the Purchase Date. Holders shall be entitled to withdraw their election
if the Trustee or the Issuers receives not later than one Business Day prior to
the Purchase Date, a telegram, telex, facsimile transmission or letter setting
forth the name of the Holder, the principal amount of the Security which was
delivered by the Holder for purchase and a statement that such Holder is
withdrawing his election to have such Security purchased. If at the expiration
of the Offer Period the aggregate principal amount of Securities surrendered by
Holders exceeds the Offer Amount, the Issuers shall select the Securities to be
purchased on a pro rata basis (with such adjustments as may be deemed
appropriate by the Issuers so that only Securities in denominations of $1, or
integral multiples thereof, shall be purchased). Holders whose Securities are
purchased only in part will be issued new Securities equal in principal amount
to the unpurchased portion of the Securities surrendered.

            (4) At the time the Issuers deliver Securities to the Trustee which
are to be accepted for purchase, the Issuers shall also deliver an Officers'
Certificate stating that such Securities are to be accepted by the Issuers
pursuant to and in accordance with the terms of this Section. A Security shall
be deemed to have been accepted for purchase at the time the Trustee, directly
or through an agent, mails or delivers payment therefor to the surrendering
Holder.

            (d) The Issuers shall comply, to the extent applicable, with the
requirements of Section 14(e) of the Exchange Act and any other securities laws
or regulations in connection with the repurchase of Securities pursuant to this
Section. To the extent that the provisions of any securities laws or regulations
conflict with provisions of this Section, the Issuers shall comply with the
applicable securities laws and regulations and shall not be deemed to have
breached its obligations under this Section by virtue thereof.

Operations. (a) If the Company does not achieve Profitable Operations prior to

thereof on the date of purchase, plus accrued and unpaid interest and Additional
Amounts, if any, thereon ("Stage III Tender").

be a senior obligation of such Restricted Subsidiary.

            SECTION 4.09 Limitation on Dividends and Other Payment Restrictions

pay dividends or make any other distribution on its Capital Stock to the Issuers
or the Company or any other Restricted Subsidiary, (b) pay any Indebtedness owed
to the Issuers or the Company or any other Restricted Subsidiary, (c) make any

agreement effecting a Refinancing of Indebtedness referred to in clause (i),
(ii) or (iii) above or this clause (iv); provided that the terms and conditions
of any such encumbrances or restrictions are not materially less favorable to
the Holders than those under or pursuant to the agreement evidencing such
Refinancing, Indebtedness so extended, renewed, refinanced or replaced.

of Control, each Holder shall have the right to require that the Issuers
repurchase all or any part of such Holder's Securities at a purchase price in

collected or assessed by or on behalf of any taxing authority within the Cayman
Islands or Thailand, unless the Issuers are or the Company is, as the case may
be, required to withhold or deduct or if the Issuers are or the Company is
otherwise required to pay any amount for or on account of Taxes imposed by a
taxing authority within the Cayman Islands or Thailand from or in respect of any
payment made under or with respect to the Securities or the Guaranty, in which
case the Issuers or the Company, as the case may be, will pay such additional
amounts ("Additional Amounts") as may be necessary so that the net amount
received by each holder and beneficial owner of Securities (including Additional
Amounts) after such withholding or deduction or other payment of Taxes will not
be less than the amount the holder and beneficial owner would have received if
such Taxes had not been withheld or deducted or paid; provided, however, that no
Additional Amounts will be payable with respect to a payment made to a holder of
Securities with respect to any Tax: (i) which would not have been imposed,

form ("Definitive Registered Securities") and the presentation of Definitive
Registered Securities for 


                                      -50-


payment had occurred within 30 days after the date such payment was due and
payable or was provided for, whichever is later, except for Additional Amounts
with respect to Taxes that would have been imposed had the holder presented the
Security for payment within such 30-day period; (iii) that is an estate,
inheritance, gift, sales, transfer, personal property or similar Tax; (iv) that
is imposed or withheld by reason of the failure of the holder or beneficial
owner of a Security to comply, at the reasonable request of the Issuers or the
Company, as the case may be, with certification, information or other reporting
requirements concerning the nationality, residence or identity of the holder or
such beneficial owner if such compliance is required or imposed by a statute,
treaty, regulation or administrative practice of the taxing jurisdiction as a
precondition to exemption from all or part of such Tax; (v) if the beneficial
owner of, or person ultimately entitled to obtain an interest in, such
Securities had been the holder of the Securities and would not be entitled to
the payment of Additional Amounts; or (vi) payable otherwise than by withholding
from payments on or in respect of any Security.

            (b) The Issuers or the Company, as the case may be, will also (i)
make such withholding or deduction and (ii) remit the full amount deducted or
withheld to the relevant authority in accordance with applicable law. The
Issuers or the Company, as the case may be, will make reasonable efforts to
obtain certified copies of tax receipts evidencing the payment of any Taxes so
deducted or withheld from each taxing authority imposing such Taxes. The Issuers
or the Company, as the case may be, will furnish to the holders of the
Securities, within 60 days after the date the payment of any Taxes so deducted
or withheld is due pursuant to applicable law, either certified copies of tax
receipts evidencing such payment by the Issuers or the Company, as the case may
be, or, if such receipts are not obtainable, other evidence of such payments by
the Issuers or the Company.

            (c) In addition, the Issuers or the Company, as the case may be,
will, upon written request of each holder of Securities (subject to the
exclusions set forth in (i), (ii), (iii), (iv), (v) and (vi) of paragraph (a)
above), and provided that reasonable supporting documentation is provided,
reimburse each such holder for the amount of any Taxes levied or imposed by the
Cayman Islands or Thailand and paid by such holder as a result of payments made
under or with respect to the Securities or under the Guaranty. Any payment
pursuant to this section shall be an Additional Amount.

            (d) At least 30 days prior to each date on which any payment under
or with respect to the Securities or under the Guaranty is due and payable, if
the Issuers or the Company will be obligated to pay Additional Amounts with
respect to such payment, the Issuers or the Company will deliver to the Trustee
an Officers' Certificate stating the fact that such Additional Amounts will be
payable and the amounts so payable and will set forth such other information
necessary to enable the Trustee to pay such Additional Amounts to the holders of
Securities on the payment date. Whenever in this Indenture or in the Securities
there is mentioned, in any context, the payment of amounts based upon the
principal of, premium, if any, interest or of any other amount payable under or
with respect to any Security or either Guaranty such mention shall be deemed to
include mention of the payment of Additional Amounts to the extent that, in such
context, Additional Amounts are, were or would be payable in respect thereof.


                                      -51-


            (e) In addition, the Issuers will pay any stamp, issue,
registration, documentary, value added or other similar taxes and other duties
(including interest and penalties) payable in the Cayman Islands or in Thailand

the United States in respect of the creation, issue, offering, execution or
enforcement of the Securities, the Guaranty or any documentation with respect
thereto.

Registrar or co-registrar) where Securities may be surrendered for registration
of transfer or exchange and where notices and demands to or upon the Issuers in
respect of the Securities, this Indenture and the Guaranty may be served. The
Issuers shall give prior written notice to the Trustee of the location, and any
change in the location, of such office or agency. If at any time the Issuers
shall fail to maintain any such required office or agency or shall fail to
furnish the Trustee with the address thereof, such presentations, surrenders,
notices and demands may be made or served at the Corporate Trust Office of the
Trustee.

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

benefit or advantage of, any stay, extension or usury law wherever enacted, now
or at any time hereafter in force, that may affect the covenants or the
performance of this Indenture (including, but not limited to, the payment of the
principal of or interest on the Securities); and the Issuers and the Company (to
the extent that they may lawfully do so) hereby expressly waive all benefit or
advantage of any such law, and covenant that they shall not, by resort to any
such law, 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 has been enacted.

thereafter to the Collateral Agent a summary of the insurance carried by it
together with certificates of insurance and other evidence of such insurance, if
any, naming the Collateral Agent as an additional insured and/or loss payee.

      Subsidiaries with the Company's officers, and (with the consent of the

            SECTION 4.32 Other Covenants. (a) The Company will not consent to

                                      -56-


            (c) The Majority Holders shall be entitled, at each annual meeting
      of stockholders or special meeting to elect directors, to elect one member
      of the Board of Directors of the Company. The Company shall take all
      action necessary for one member of the Board of Directors to be elected by
      the Majority Holders at each annual meeting of stockholders or special
      meeting to elect directors. The Majority Holders shall notify the Company
      of the name of the member of the Board of Directors selected by the
      Majority Holders pursuant to this Section 4.32(b). Notwithstanding the
      foregoing, for so long as John Hancock Mutual Life Insurance Co.
      ("Hancock") or any of its Affiliates are Holders of any of the Securities,
      then Hancock shall be entitled to exercise such nomination rights.

            (d) The Company shall cause to be deposited in the Offshore
      Sub-Account all non-Baht revenue, including all proceeds from the sale of
      goods and services, all insurance proceeds, all proceeds from the Working
      Capital Credit Facility and all other amounts received by the Company that
      are otherwise not required to be deposited in the Notes DSR Account or the
      Offshore Reserve Account. Amounts held in the Offshore Sub-Account may be
      used by the Company for payments and other uses permitted by the
      Indentures but (other than payments of interest on the Senior Notes, the
      Senior Subordinated Notes and the Securities or deposits into the Notes
      Sinking Fund Account) only to the extent all other amounts on deposit in
      the US$ Revenue Account and Baht Revenue Account (both as defined in the
      Security Sharing Agreement) are insufficient to make such payments.

            (e) Commencing with the first fiscal quarter of the Company ending
      after the first anniversary of the Issue Date, and for each fiscal quarter
      thereafter, the Company will deposit into the Notes Sinking Fund Account
      the greater of $15 million or one-fourth the amount of $ U.S. denominated
      interest on indebtedness of the Company or the Issuers due in the fiscal
      year in which such fiscal quarter falls; provided, however, that any
      amounts so deposited may be withdrawn at any time in order to pay interest
      and/or principal on any $ U.S. denominated indebtedness of the Company or
      the Issuers or, in the event that the Company reasonably believes that it
      or the Issuers is about to default on any Baht denominated indebtedness,
      to pay interest and/or principal on such Baht denominated indebtedness. By
      way of clarification, notwithstanding the fact that Section 2.3(c) of
      Annex A to the Security Sharing Agreement would otherwise allow the
      Company to do so, the Company agrees that it shall not withdraw funds from
      the Notes Sinking Fund Account solely as a result of obtaining Profitable
      Operations, and shall only withdraw funds therefrom if otherwise permitted
      hereunder and under the terms of the Security Sharing Agreement.

            (f) Upon any discharge of any one or more of the Credit Facilities,
      the Senior Notes or the Senior Subordinated Notes, the Issuers and the
      Company hereby agree to enter into such conforming changes to the Security
      Documents as shall be reasonably satisfactory to the Trustee in order to
      confirm the rights provided to the Holders (including the second priority
      interests granted thereunder), which conforming changes shall mutatis
      mutandis give effect to the discharge of the Credit Facilities, the Senior
      Notes or the Senior Subordinated Notes, as applicable.

Agreement, the Security Documents, and the Securities remain and will be in full
force and effect against all applicable parties and the Liens with respect to

                                      -58-

                                      -60-


            However, a Default under clauses (d) or (e) will not constitute an
Event of Default until the Trustee or the holders of 25% in principal amount at
maturity of the outstanding Securities, notify the Issuers (with a copy to the
Trustee if given by the holders) of the Default and such default is not cured
within the time specified in clause (d) or (e) after receipt of such notice. The
written notice must specify the Default, demand that it be remedied and state
that the notice is a "Notice of Default".

            The term "Bankruptcy Law" means Title 11, United States Code, or any
similar U.S. Federal, state or local law for the relief of debtors or any
comparable or similar foreign laws (including any Thai law) relating to
bankruptcy, receivership, liquidation, dissolution or similar proceeding. The
term "Custodian" means any receiver, trustee, assignee, liquidator, custodian or
similar official under any Bankruptcy Law.

            The Issuers shall deliver to the Trustee, within 30 days after the
occurrence thereof, written notice in the form of an Officers' Certificate of
any Event of Default and of any event which with the giving of notice or the
lapse of time would become an Event of Default under clause (a), (d), (e), (g),
(j) or (k), its status and what action the Issuers is taking or proposes to take
with respect thereto.

            SECTION 6.02 Acceleration. If an Event of Default (other than an
Event of Default with respect to clauses (h) or (i) of Section 6.01 occurs and
is continuing, the Trustee or the Holders of at least 25% in principal amount at
maturity of the outstanding Securities by notice to the Issuers and the Trustee
(if the notice is given by the holders) may declare the Accreted Value of, and
accrued and unpaid interest, if any, on all the Securities to be due and
payable. Upon such a declaration, such Accreted Value and accrued and unpaid
interest shall be due and payable immediately. If an Event of Default with
respect to the Securities pursuant to clauses (h) and (i) of Section 6.01
(together, the "bankruptcy provision") occurs, the Accreted Value of, and
accrued and unpaid interest on, such Securities will become and be immediately
due and payable without any declaration or other act on the part of the Trustee
or any holders. The Holders of a special majority of 60% in principal amount of
the outstanding Securities by notice to the Trustee may rescind an acceleration
and its consequences if (i) the rescission would not conflict with any judgment
or decree, (ii) all existing Events of Default have been cured or waived except
nonpayment of principal or interest that has become due solely because of
acceleration and (iii) all amounts due to the Trustee under Section 7.07 have
been paid. No such rescission shall affect any subsequent Default or Event of
Default or impair any right consequent thereto. Upon any such acceleration,
Securityholders holding a majority and principal amount at maturity of the
Securities shall have the right under the Security Documents to vote to cause
the Trustee to direct the Collateral Agent to act thereunder. Except as directed
by the Securityholders, the Trustee shall have no responsibility before or after
an Event of Default to foreclose or take any other action with respect to the
Collateral or the Security Documents.

            SECTION 6.03 Other Remedies. If an Event of Default occurs and is
continuing, the Trustee may pursue any available remedy to collect the payment
of principal of or interest on the Securities or to enforce the performance of
any provision of the Securities or this Indenture.


                                      -61-


            The Trustee may maintain a proceeding even if it does not possess
any of the Securities or does not produce any of them in the proceeding. A delay
or omission by the Trustee or any Securityholder 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. No remedy is
exclusive of any other remedy. All available remedies are cumulative.

            SECTION 6.04 Waiver of Defaults. The Majority Holders by notice to
the Trustee may waive an existing Default and its consequences except (i) a
Default in the payment of the principal of or interest on a Security or (ii) a
Default in respect of a provision that under Section 9.02 cannot be amended
without the consent of each Securityholder affected. When a Default is waived,
it is deemed cured, but no such waiver shall extend to any subsequent or other
Default or impair any consequent right.

            SECTION 6.05 Control by Majority. The Majority Holders may direct
the time, method and place of conducting any proceeding for any remedy available
to the Trustee or of exercising any trust or power conferred on the Trustee.
However, the Trustee may refuse to follow any direction that conflicts with law
or this Indenture or, subject to Section 7.01, that the Trustee determines is
unduly prejudicial to the rights of other Securityholders or would involve the
Trustee in personal liability; provided, however, that the Trustee may take any
other action deemed proper by the Trustee that is not inconsistent with such
direction. Prior to taking any action hereunder, the Trustee shall be entitled
to indemnification satisfactory to it in its sole discretion against all losses
and expenses caused by taking or not taking such action.

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

            (1) the Holder gives to the Trustee written notice stating that an
      Event of Default is continuing;

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

            (3) such Holder or Holders offer to the Trustee reasonable security
      or indemnity against any loss, liability or expense;

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

            (5) the Holders of a majority in principal amount of the outstanding
      Securities do not give the Trustee a direction inconsistent with the
      request during such 60-day period.

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

            SECTION 6.07 Rights of Holders to Receive Payment. Notwithstanding
any other provision of this Indenture, the right of any Holder to receive
payment of principal of and 


                                      -62-


liquidated damages and interest on the Securities held by such Holder, on or
after the respective due dates expressed in the Securities, or to bring suit for
the enforcement of any such payment on or after such respective dates, shall not
be impaired or affected without the consent of such Holder.

            SECTION 6.08 Collection Suit by Trustee. If an Event of Default
specified in Section 6.01(a) or (b) occurs and is continuing, the Trustee may
recover judgment in its own name and as trustee of an express trust against the
Company for the whole amount then due and owing (together with interest on any
unpaid interest to the extent lawful) and the amounts provided for in Section
7.07.

            SECTION 6.09 Trustee May File Proofs of Claim. The Trustee may file
such proofs of claim and other papers or documents as may be necessary or
advisable in order to have the claims of the Trustee and the Securityholders
allowed in any judicial proceedings relative to the Issuers, any Subsidiary or
the Company, their creditors or their property and, unless prohibited by law or
applicable regulations, may vote on behalf of the Holders in any election of a
trustee in bankruptcy or other Person performing similar functions, and any
Custodian in any such judicial proceeding is hereby authorized by each Holder to
make 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 it for the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and its counsel, and any other amounts due
the Trustee under Section 7.07.

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

            FIRST: to the Trustee for amounts due under Section 7.07;

            SECOND: subject to Articles XI and XIII, to Securityholders for
      amounts due and unpaid on the Securities for principal and interest,
      ratably, and any liquidated damages without preference or priority of any
      kind, according to the amounts due and payable on the Securities for
      principal, any liquidated damages and interest, respectively;

            THIRD: any other amounts to the Securityholders hereunder, under the
      Purchase Agreements, the Security Documents, and under any other documents
      delivered in connection herewith or therewith, which amounts shall be
      shared pro rata (based on amount owed) among all Securityholders owed any
      such amounts; and

            FOURTH: to the Company.

            The Trustee may fix a record date and payment date for any payment
to Securityholders pursuant to this Section.

            SECTION 6.11 Undertaking for Costs. In any suit for the enforcement
of any right or remedy under this Indenture or in any suit against the Trustee
for any action taken or omitted by it as Trustee, a court in its discretion may
require the filing by any party litigant in the 


                                      -63-


suit of an undertaking to pay the costs of the suit, and the court in its
discretion may assess reasonable costs, including reasonable attorneys' fees,
against any party litigant in the suit, having due regard to the merits and good
faith of the claims or defenses made by the party litigant. This Section does
not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 6.07
or a suit by Holders of more than 10% in principal amount of the Securities.

                                   ARTICLE VII

                                     Trustee

            SECTION 7.01 Duties of Trustee. (a) If an Event of Default has
occurred and is continuing, the Trustee shall exercise the rights and powers
vested in it by this Indenture and use the same degree of care and skill in
their exercise as a prudent person would exercise or use under the circumstances
in the conduct of such person's own affairs.

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

            (1) the Trustee undertakes to perform such duties and only such
      duties as are specifically set forth in this Indenture and no implied
      covenants or obligations shall be read into this Indenture against the
      Trustee; and

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

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

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

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

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

            (d) Every provision of this Indenture that in any way relates to the
Trustee is subject to paragraphs (a), (b) and (c) of this Section.

            (e) The Trustee shall not be liable for interest on any money
received by it except as the Trustee may agree in writing with the Company.

            (f) Money held in trust by the Trustee need not be segregated from
other funds except to the extent required by law.


                                      -64-


            (g) No provision of this Indenture shall require the Trustee to
expend or risk its own funds or otherwise incur 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 to believe that repayment
of such funds or adequate indemnity against such risk or liability is not
reasonably assured to it.

            (h) 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 Section and to the provisions of the TIA.

            SECTION 7.02 Rights of Trustee. Subject to Section 7.01: (a) The
Trustee may rely on any document believed by it to be genuine and to have been
signed or presented by the proper Person. The Trustee need not investigate any
fact or matter stated in the document.

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

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

            (d) The Trustee shall not be liable for any action it takes or omits
to take in good faith which it believes to be authorized or within its rights or
powers; provided, however, that the Trustee's conduct does not constitute
willful misconduct or negligence.

            (e) The Trustee may consult with counsel, and the advice or opinion
of counsel with respect to legal matters relating to this Indenture and the
Securities shall be full and complete authorization and protection from
liability in respect to any action taken, omitted or suffered by it hereunder in
good faith and in accordance with the advice or opinion of such counsel.

            (f) The Trustee shall not be bound to make any investigation into
the facts or matters stated in any resolution, certificate, statement,
instrument, opinion, report, notice, request, consent, order, approval, bond,
debenture, note or other paper or document unless requested in writing to do so
by the Holders of not less than a majority in principal amount of the Securities
at the time outstanding, but the Trustee, in its discretion, may make such
further inquiry or investigation into such facts or matters as it may see fit,
and, if the Trustee shall determine to make such further inquiry or
investigation, it shall be entitled to examine the books, records and premises
of the Issuers or the Company, personally or by agent or attorney.

            (g) The Trustee shall not be charged with knowledge of any Default
or Event of Default unless either a Trust Officer of the Trustee assigned to the
Corporate Trust Department of the Trustee (or any successor division or
department of the Trustee) shall have actual knowledge of such Default or Event
of Default or written notice of such Default or Event of Default shall have been
given to the Trustee by the Company or any Holder.


                                      -65-


            (h) Except as expressly provided in Section 10.04, the Trustee shall
at no time have any responsibility or liability for or with respect to the
legality, validity or enforceability of any Collateral or any arrangement or
agreement between the Collateral Agent and any Person with respect thereto, or
the perfection or priority of any security interest created in any of the
Collateral or the maintenance of any such perfection and priority, or for or
with respect to the sufficiency of the Collateral following any Event of
Default. The Trustee shall have no responsibility for the maintenance of any
Account or the investment of any funds deposited therein or the release of any
funds therefrom.

            SECTION 7.03 Individual Rights of Trustee. The Trustee in its
individual or any other capacity may become the owner or pledgee of Securities
and may otherwise deal with the Issuers or their Affiliates with the same rights
it would have if it were not Trustee. Any Paying Agent, Registrar, co-registrar
or co-paying agent may do the same with like rights. However, the Trustee must
comply with Sections 7.10 and 7.11.

            SECTION 7.04 Trustee's Disclaimer. The Trustee shall not be
responsible for and makes no representation as to the validity or adequacy of
this Indenture, the Securities, the Guaranty, any Collateral or any Account, it
shall not be accountable for the Issuers' use of the proceeds from the
Securities, and it shall not be responsible for any statement of the Issuers in
this Indenture or in any document issued in connection with the sale of the
Securities or in the Securities other than the Trustee's certificate of
authentication.

            SECTION 7.05 Notice of Defaults. If a Default occurs and is
continuing and if it is known to the Trustee, the Trustee shall mail to each
Securityholder notice of the Default within 30 days after it is known to a Trust
Officer or written notice of it is received by the Trustee. Except in the case
of a Default in payment of principal of, premium (if any) or interest on any
Security (including payments pursuant to the mandatory redemption provisions of
such Security, if any), the Trustee may withhold the notice if and so long as a
committee of its Trust Officers in good faith determines that withholding the
notice is in the interests of Securityholders.

            SECTION 7.06 Reports by Trustee to Holders. As promptly as
practicable after each May 15 beginning with the May 15 following the date of
this Indenture, and in any event prior to July 15 in each year, the Trustee
shall mail to each Securityholder a brief report dated as of May 15 that
complies with Section 313(a) of the TIA. The Trustee shall also comply with
Section 313(b) of the TIA.

            A copy of each report at the time of its mailing to Securityholders
shall be filed with the SEC and each stock exchange (if any) on which the
Securities are listed. The Issuers agree to notify promptly the Trustee whenever
the Securities become listed on any stock exchange and of any delisting thereof.

            SECTION 7.07 Compensation and Indemnity. The Issuers and the Company
jointly and severally agree to pay to the Trustee from time to time reasonable
compensation for its services as set forth in a separate fee letter. The
Trustee's compensation shall not be limited by any law on compensation of a
trustee of an express trust. The Issuers and the Company jointly and severally
agree to reimburse the Trustee upon request for all reasonable out-of-pocket


                                      -66-


expenses incurred or made by it, including costs of collection, in addition to
the compensation for its services. Such expenses shall include the reasonable
compensation and expenses, disbursements and advances of the Trustee's agents,
counsel, accountants and experts. The Issuers and the Company, jointly and
severally shall indemnify the Trustee against any and all loss, liability or
expense (including reasonable attorneys' fees) incurred by it without negligence
or bad faith on its part in connection with the administration of this trust and
the performance of its duties hereunder. The Trustee shall notify the Issuers of
any claim for which it may seek indemnity promptly upon obtaining actual
knowledge thereof; provided that any failure so to notify the Issuers shall not
relieve the Issuers or the Company of its indemnity obligations hereunder. The
Issuers shall defend the claim and the indemnified party shall provide
reasonable cooperation at the Issuers' expense in the defense. Such indemnified
parties may have separate counsel and the Issuers shall pay the fees and
expenses of such counsel. The Issuers need not reimburse any expense or
indemnify against any loss, liability or expense incurred by an indemnified
party through such party's own willful misconduct, negligence or bad faith.

            To secure the Issuers' payment obligations in this Section, the
Trustee shall have a lien prior to the Securities on all money or property held
or collected by the Trustee other than money or property held in trust to pay
principal of and interest and any liquidated damages on particular Securities.

            The Issuers' payment obligations pursuant to this Section shall
survive the satisfaction or discharge of this Indenture, any rejection or
termination of this Indenture under any bankruptcy law or the resignation or
removal of the Trustee. Without prejudice to any other rights available to the
Trustee under applicable law, when the Trustee incurs expenses after the
occurrence of an Event of Default specified in Section 6.01(h) or (i) with
respect to the Issuers, the expenses are intended to constitute expenses of
administration under the Bankruptcy Law.

            SECTION 7.08 Replacement of Trustee. The Trustee may resign at any
time by so notifying the Issuers; provided that such resignation shall not be
effective until a successor is appointed. The Holders of a majority in principal
amount of the Securities may remove the Trustee by so notifying the Trustee and
may appoint a successor Trustee. The Issuers shall remove the Trustee if:

            (1) the Trustee fails to comply with Section 7.10 of this Indenture
      or fails to qualify as Book-Entry Depositary pursuant to Section 3.07 of
      the Debenture Depositary Agreement;

            (2) the Trustee is adjudged bankrupt or insolvent;

            (3) a receiver or other public officer takes charge of the Trustee
      or its property; or

            (4) the Trustee otherwise becomes incapable of acting.

            If the Trustee resigns, is removed or if a vacancy exists in the
office of Trustee for any reason (the Trustee in such event being referred to
herein as the retiring Trustee), the Issuers shall promptly appoint a successor
Trustee (subject to the preceding paragraph).


                                      -67-


            A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Issuers. Thereupon the
resignation or removal of the retiring Trustee shall become effective, and the
successor Trustee shall have all the rights, powers and duties of the Trustee
under this Indenture. The successor Trustee shall mail a notice of its
succession to Securityholders. The retiring Trustee shall promptly transfer all
property held by it as Trustee to the successor Trustee, subject to the lien
provided for in Section 7.07.

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

            If the Trustee fails to comply with Section 7.10, any Securityholder
may petition any court of competent jurisdiction for the removal of the Trustee
and the appointment of a successor Trustee.

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

            SECTION 7.09 Successor Trustee by Merger. If the Trustee
consolidates with, merges or converts into, or transfers all or substantially
all its corporate trust business or assets to, another corporation or banking
association, the resulting, surviving or transferee corporation without any
further act shall be the successor Trustee.

            In case at the time such successor or successors by merger,
conversion or consolidation to the Trustee shall succeed to the trusts created
by this Indenture any of the Securities shall have been authenticated but not
delivered, any such successor to the Trustee may adopt the certificate of
authentication of any predecessor trustee, and deliver such Securities so
authenticated; and in case at that time any of the Securities shall not have
been authenticated, any successor to the Trustee may authenticate such
Securities either in the name of any predecessor hereunder or in the name of the
successor to the Trustee; and in all such cases such certificates shall have the
full force which it is anywhere in the Securities or in this Indenture provided
that the certificate of the Trustee shall have.

            SECTION 7.10 Eligibility; Disqualification. The Trustee shall at all
times satisfy the requirements of TIA ss. 310(a). The Trustee shall have a
combined capital and surplus of at least $50,000,000 as set forth in its most
recent published annual report of condition. The Trustee shall comply with TIA
ss. 310(b); provided, however, that there shall be excluded from the operation
of TIA ss. 310(b)(1) any indenture or indentures under which other securities or
certificates of interest or participation in other securities of the Issuers are
outstanding if the requirements for such exclusion set forth in TIA ss.
310(b)(1) are met.

            SECTION 7.11 Preferential Collection of Claims Against Issuers. The
Trustee shall comply with TIA ss. 311(a), excluding any creditor relationship
listed in TIA ss. 311(b). A Trustee who has resigned or been removed shall be
subject to TIA ss. 311(a) to the extent indicated.


                                      -68-


                                  ARTICLE VIII

                       Discharge of Indenture; Defeasance

            SECTION 8.01 Discharge of Liability on Securities; Defeasance. (a)
When (i) the Issuers deliver to the Trustee all outstanding Securities (other
than Securities replaced pursuant to Section 2.07) for cancellation or (ii) all
outstanding Securities have become due and payable, whether at maturity or as a
result of the mailing of a notice of redemption pursuant to Article III hereof
and the Issuers irrevocably deposit with the Trustee funds or U.S. Government
Obligations on which payment of principal and interest when due will be
sufficient to pay at maturity or upon redemption all outstanding Securities,
including interest thereon to maturity or such redemption date (other than
Securities replaced pursuant to Section 2.07), and if in either case the Issuers
pay all other sums payable hereunder by the Issuers, then this Indenture shall,
subject to Section 8.01(c), cease to be of further effect. The Trustee shall
acknowledge satisfaction and discharge of this Indenture on demand of the
Issuers accompanied by an Officers' Certificate and an Opinion of Counsel and at
the cost and expense of the Issuers.

            (b) Subject to Sections 8.01(c) and 8.02, the Issuers at any time
may terminate (i) all of their obligations under the Securities and this
Indenture ("legal defeasance option") or (ii) their obligations under Article IV
(other than those in Sections 4.01, 4.11, 4.21 and 4.29), Sections 5.01(iii) and
5.01(iv) and the operation of Section 6.01(d) (except with respect to Sections
4.01, 4.11, 4.21 and 4.29), 6.01(g), 6.01(h) (with respect to Subsidiaries of
the Issuers only), 6.01(i) (with respect to Subsidiaries of the Issuers only),
6.01(j), 6.01(k) and 6.01(l) ("covenant defeasance option"). The Issuers may
exercise their legal defeasance option notwithstanding their prior exercise of
their covenant defeasance option. If the Issuers exercise their legal defeasance
option or their covenant defeasance option, the Company shall be released from
all of its obligations with respect to its Guaranty and all the Collateral will
be released.

            If the Issuers exercise their legal defeasance option, payment of
the Securities may not be accelerated because of an Event of Default. If the
Issuers exercise their covenant defeasance option, payment of the Securities may
not be accelerated because of an Event of Default specified in Section 6.01(d)
(except with respect to Section 4.01, 4.11, 4.21 and 4.29), 6.01(e), 6.01(f),
6.01(g), 6.01(h) (with respect only to the Company and its Subsidiaries other
than the Issuers only), 6.01(i) (with respect to Subsidiaries of the Issuers
only), 6.01(j), 6.01(k) or 6.01(l) or because of the failure of the Issuers to
comply with (iii) and (iv) of Section 5.01.

            Upon satisfaction of the conditions set forth herein and upon
request of the Issuers, the Trustee shall acknowledge in writing the discharge
of those obligations that the Issuers terminate.

            (c) Notwithstanding clauses (a) and (b) above, the Issuers'
obligations in Sections 2.03, 2.04, 2.05, 2.06, 2.07, 7.07, 7.08, 8.04, 8.05 and
8.06 shall survive until the Securities have been paid in full. Thereafter, the
Issuers' obligations in Sections 7.07, 8.04 and 8.05 shall survive.


                                      -69-


            SECTION 8.02 Conditions to Defeasance. The Issuers may exercise
their legal defeasance option or its covenant defeasance option only if:

            (1) the Issuers irrevocably deposit in trust with the Trustee money
      in the form of U.S. dollars or U.S. Government Obligations for the payment
      of principal and interest on the Securities to maturity or redemption, as
      the case may be;

            (2) the Issuers deliver to the Trustee a certificate from a
      nationally recognized firm of independent accountants expressing their
      opinion that the payments of principal and interest when due and without
      reinvestment of the deposited U.S. Government Obligations plus any
      deposited money without investment will provide cash at such times and in
      such amounts as will be sufficient to pay principal and interest when due
      on all the Securities to maturity or redemption, as the case may be;

            (3) 123 days, or such longer period as may be relevant under any
      applicable foreign Bankruptcy Laws, pass after the deposit is made and
      during the 123-day or such applicable other period no Default specified in
      Section 6.01(h) or (i) with respect to the Issuers occurs which is
      continuing at the end of the period;

            (4) the deposit does not constitute a default under any other
      agreement binding on the Issuers;

            (5) the Issuers deliver to the Trustee an Opinion of Counsel to the
      effect that the trust resulting from the deposit does not constitute, or
      is qualified as, a regulated investment company under the Investment
      Company Act of 1940;

            (6) in the case of the legal defeasance option, the Issuers shall
      have delivered to the Trustee an Opinion of Counsel stating that (i) the
      Issuers have received from, or there has been published by, the Internal
      Revenue Service a ruling, or (ii) since the date of this Indenture there
      has been a change in the applicable federal income tax or Thailand tax
      law, in either case to the effect that, and based thereon such Opinion of
      Counsel shall confirm that, the Securityholders will not recognize income,
      gain or loss for Federal income or Thailand tax purposes as a result of
      such defeasance and will be subject to federal income or Thailand tax on
      the same amounts, in the same manner and at the same times as would have
      been the case if such defeasance had not occurred;

            (7) in the case of the covenant defeasance option, the Issuers shall
      have delivered to the Trustee an Opinion of Counsel to the effect that the
      Securityholders will not recognize income, gain or loss for Federal income
      or Thailand tax purposes as a result of such covenant defeasance and will
      be subject to Federal income and Thailand tax on the same amounts, in the
      same manner and at the same times as would have been the case if such
      covenant defeasance had not occurred; and

            (8) the Issuers deliver to the Trustee an Officers' Certificate and
      an Opinion of Counsel, each stating that all conditions precedent to the
      defeasance and discharge of the Securities as contemplated by this Article
      VIII have been complied with.


                                      -70-


            Before or after a deposit, the Issuers may make arrangements
satisfactory to the Trustee for the redemption of Securities at a future date in
accordance with Article III.

            SECTION 8.03 Application of Trust Money. The Trustee shall hold in
trust money or U.S. Government Obligations deposited with it pursuant to this
Article VIII. It shall apply the deposited money and the money from U.S.
Government Obligations through the Paying Agent and in accordance with this
Indenture to the payment of principal of and interest on the Securities.

            SECTION 8.04 Repayment to Issuers. The Trustee and the Paying Agent
shall promptly turn over to the Issuers upon request any excess money or
securities held by them at any time.

            Subject to any applicable abandoned property law, the Trustee and
the Paying Agent shall pay to the Issuers upon written request any money held by
them for the payment of principal or interest that remains unclaimed for two
years, and, thereafter, Securityholders entitled to the money must look to the
Issuers for payment as general creditors.

            SECTION 8.05 Indemnity for Government Obligations. The Issuers shall
jointly and severally pay and shall indemnify the Trustee against any tax, fee
or other charge imposed on or assessed against deposited U.S. Government
Obligations or the principal and interest received on such U.S. Government
Obligations.

            SECTION 8.06 Reinstatement. If the Trustee or Paying Agent is unable
to apply any money or U.S. Government Obligations in accordance with this
Article VIII by reason of any legal proceeding or by reason of any order or
judgment of any court or Governmental Authority enjoining, restraining or
otherwise prohibiting such application, the Issuers' obligations under this
Indenture and the Securities shall be revived and reinstated as though no
deposit had occurred pursuant to this Article VIII until such time as the
Trustee or Paying Agent is permitted to apply all such money or U.S. Government
Obligations in accordance with this Article VIII; provided, however, that, if
the Issuers have made any payment of interest on or principal of any Securities
because of the reinstatement of its obligations, the Issuers shall be subrogated
to the rights of the Holders of such Securities to receive such payment from the
money or U.S. Government Obligations held by the Trustee or Paying Agent.

                                   ARTICLE IX

                                   Amendments

            SECTION 9.01 Without Consent of Holders. The Issuers, the Company
and the Trustee may amend this Indenture, any Security Documents, the Securities
or the Guaranty without notice to or consent of any Securityholder:

            (1) to cure any ambiguity, omission, defect or inconsistency;

            (2) to comply with Article V;


                                      -71-


            (3) to provide for uncertificated Securities in addition to or in
      place of certificated Securities; provided, however, that the
      uncertificated Securities are issued in registered form for purposes of
      Section 163(f) of the Code or in a manner such that the uncertificated
      Securities are described in Section 163(f)(2)(B) of the Code;

            (4) to add further Guaranties with respect to the Securities or to
      further secure the Securities;

            (5) to add to the covenants of the Issuers for the benefit of the
      Holders or to surrender any right or power herein conferred upon the
      Issuers or any Securityholder;

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

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

            (8) to provide for the issuance of the Exchange Securities, which
      shall have terms substantially identical in all material respects to the
      Initial Securities (except that the transfer restrictions contained in the
      Initial Securities shall be modified or eliminated, as appropriate), and
      which shall be treated, together with any outstanding Initial Securities,
      as a single issue of securities.

            After an amendment under this Section becomes effective, the Issuers
shall mail to Securityholders a notice briefly describing such amendment. The
failure to give such notice to all Securityholders, or any defect therein, shall
not impair or affect the validity of an amendment under this Section.

            SECTION 9.02 With Consent of Holders. The Issuers, the Company and
the Trustee may amend this Indenture, any Security Documents, the Securities or
the Guaranty without notice to any Securityholder but with the written consent
of the Majority Holders. However, without the consent of each Securityholder
affected, an amendment, supplement or waiver may not:

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

            (2) reduce the stated rate of or extend the stated time for payment
      of interest or any liquidated damages on any Security;

            (3) reduce the principal of or extend the Stated Maturity of any
      Security;

            (4) reduce the premium payable upon the redemption of any Security
      or change the time at which any Security may be redeemed or repurchased in
      accordance with Article III;

            (5) make any Security payable in money other than that stated in the
      Security;


                                      -72-


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

            (7) make any change in Section 6.04 or 6.07 or this Section; or

            (8) release the Guaranty, all or substantially all of the Collateral
      or the requirement to maintain any Account.

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

            After an amendment under this Section becomes effective, the Issuers
shall mail to Securityholders a notice briefly describing such amendment. The
failure to give such notice to all Securityholders, or any defect therein, shall
not impair or affect the validity of an amendment under this Section.

            SECTION 9.03 Compliance with Trust Indenture Act. Every amendment to
this Indenture or the Securities shall comply with the TIA as then in effect.

            SECTION 9.04 Revocation and Effect of Consents and Waivers. A
consent to an amendment or a waiver by a Holder of a Security shall bind the
Holder and every subsequent Holder of that Security or portion of the Security
that evidences the same debt as the consenting Holder's Security, even if
notation of the consent or waiver is not made on the Security. However, any such
Holder or subsequent Holder may revoke the consent or waiver as to such Holder's
Security or portion of the Security if the Trustee receives the notice of
revocation before the date the amendment or waiver becomes effective. After an
amendment or waiver becomes effective, it shall bind every Securityholder. An
amendment or waiver becomes effective once the requisite number of consents are
received by the Issuers or the Trustee.

            The Issuers may, but shall not be obligated to, fix a record date
for the purpose of determining the Securityholders entitled to give their
consent or take any other action described above or required or permitted to be
taken pursuant to this Indenture. If a record date is fixed, then
notwithstanding the immediately preceding paragraph, those Persons who were
Securityholders at such record date (or their duly designated proxies), and only
those Persons, shall be entitled to give such consent or to revoke any consent
previously given or to take any such action, whether or not such Persons
continue to be Holders after such record date. No such consent shall be valid or
effective for more than 120 days after such record date.

            SECTION 9.05 Notation on or Exchange of Securities. If an amendment
changes the terms of a Security, the Trustee may require the Holder of the
Security to deliver it to the Trustee. The Trustee may place an appropriate
notation on the Security regarding the changed terms and return it to the
Holder. Alternatively, if the Issuers or the Trustee so determines, the Issuers
in exchange for the Security shall issue and the Trustee shall authenticate a
new Security

                                      -73-


that reflects the changed terms. Failure to make the appropriate notation or to
issue a new Security shall not affect the validity of such amendment.

            SECTION 9.06 Trustee to Sign Amendments. The Trustee shall sign any
amendment authorized pursuant to this Article IX if the amendment does not
adversely affect the rights, duties, liabilities or immunities of the Trustee.
If it does, the Trustee may but need not sign it. In signing such amendment the
Trustee shall be entitled to receive indemnity reasonably satisfactory to it and
to receive, and (subject to Section 7.01) shall be fully protected in relying
upon, an Officers' Certificate and an Opinion of Counsel stating, in addition to
the requirements of Section 12.04, that such amendment is authorized or
permitted by this Indenture that such amendment is the legal, valid and binding
obligation of the Issuers and the Company enforceable against them in accordance
with its terms, subject to customary exceptions, and complies with the
provisions hereof (including Section 9.03).

            SECTION 9.07 Payment for Consent. Neither the Issuers nor any
Affiliate of the Issuers 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 or the Securities unless such consideration is
offered to be paid to all Holders that so consent, waive or agree to amend in
the time frame set forth in solicitation documents relating to such consent,
waiver or agreement.

                                    ARTICLE X

                               Security Documents

            SECTION 10.01 Collateral and Security Documents. (a) To secure the
due and punctual payment of the obligations of the Issuers and the Company under
this Indenture and the Securities, the Issuers, the Company, the Trustee and the
Collateral Agent have entered into the Security Documents to create the security
interests and related matters. The Trustee, the Issuers and the Company hereby
acknowledge and agree that the Collateral Agent holds the Collateral in trust
for the benefit of the Holders and the Trustee and the other parties secured
under the Security Documents pursuant to the terms of the Security Documents.

            (b) Each Holder, by accepting a Security, agrees to all of the terms
and provisions of the Security Documents, as the same may be amended from time
to time pursuant to the provisions of the Security Documents and this Indenture,
and authorizes and directs the Collateral Agent to perform its obligations and
exercise its rights under the Security Documents in accordance therewith;
provided, however, that if any provisions of the Security Documents limit,
qualify or conflict with the duties imposed by the provisions of the TIA, the
TIA will control.

            (c) As more fully set forth in, and subject to the provisions of,
the Security Documents, the Holders, and the Trustee on behalf of such Holders,
have rights in and to the Collateral which are second in priority and
subordinated to the rights created in favor of the creditors under the Bank
Credit Facility and the holders of the Notes.


                                      -74-


            (d) As set forth in and governed by the Security Documents, the
Collateral as now or hereafter constituted shall be held for the benefit of the
Secured Creditors (as defined in the Security Documents) with the preference,
priority or distinction set forth in the Security Documents. 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.

            SECTION 10.02 Release of Collateral. Collateral may be released from
the security interest created by the Security Documents at any time or from time
to time in accordance with the provisions of the Security Documents. The release
of any Collateral from the terms hereof and of the Security Documents or the
release of, in whole or in part, the Liens created by the Security Documents,
will not be deemed to impair the Lien on the Collateral in contravention of the
provisions hereof if and to the extent the Collateral or Liens are released
pursuant to the applicable Security Documents and pursuant to the terms of this
Article 10. The Trustee and each of the Holders acknowledge that a release of
Collateral or a Lien strictly in accordance with the terms of the Security
Documents and of this Article 10 will not be deemed for any purpose to be an
impairment of the Lien on the Collateral in contravention of the terms of this
Indenture. To the extent applicable, the Company and each obligor on the
Securities shall cause ss. 314(d) of the TIA relating to the release of property
or securities from the Lien hereof and of the Security Documents to be complied
with. Any certificate or opinion required by ss. 314(d) of the TIA may be made
by an officer of the Company, except in cases which ss. 314(d) of the TIA
requires that such certificate or opinion be made by an independent person.

            SECTION 10.03 Certificates and Opinions. (a) The Issuers and the
Company shall deliver to the Trustee:

            (i) promptly after the execution and delivery of this Indenture, an
      Opinion of Counsel either stating that in the opinion of such counsel the
      Indenture and the Security Documents (including financing statements or
      other instruments) have been properly recorded and filed so as to make
      effective the security interest intended to be created for the benefit of
      the Securityholders, and reciting the details of such action, or stating
      that in the opinion of such counsel no such action is necessary to make
      such Lien effective; and

            (ii) on or before March 1 of each year, an Opinion of Counsel either
      stating that in the opinion of such counsel such action has been taken
      with respect to the recording, filing, re-recording and re-filing of the
      Indenture and the Security Documents (including financing statements or
      other instruments) as is necessary to maintain the security interest
      intended to be created thereby for the benefit of the Securityholders, and
      reciting the details of such action, or stating that in the opinion of
      such counsel no such action is necessary to maintain such Lien.

            (b) The Company shall comply with TIA ss. 314(d), relating to, among
other matters, the release of Collateral from the Lien of the Security Documents
and Officers' Certificates or other documents regarding fair value of the
Collateral, to the extent such provisions are applicable. Any certificate or
opinion required by TIA ss. 314(d) may be executed and delivered by an Officer
of the Company to the extent permitted by TIA ss. 314(d).


                                      -75-


            SECTION 10.04 Directions to Collateral Agent. Except during the
continuance of an Event of Default, the Trustee in directing the Collateral
Agent to take or refrain from taking actions under the Security Documents may
rely on an Officers' Certificate and Opinion of Counsel delivered to it by the
Company to the effect that the action to be taken or not taken does not
adversely affect the interests of the Securityholders or impair the security of
the Securityholders in contravention of the provisions of the Security Documents
or this Indenture.

                                   ARTICLE XI

                           Subordination of Securities

            SECTION 11.01 Agreement to Subordinate. The Issuers agree, and each
Securityholder by accepting a Security agrees, that the Indebtedness evidenced
by the Securities is subordinated in right of payment to the extent and in the
manner provided in this Article XI, to the prior payment in full in cash or cash
equivalents of all Specified Senior Indebtedness of the Issuers and that the
subordination is for the benefit of and enforceable by the holders of such
Specified Senior Indebtedness. The Securities shall in all respects rank pari
passu with all other Senior Indebtedness of the Issuers and only Indebtedness of
the Issuers which is Specified Senior Indebtedness shall rank senior to the
Securities in accordance with the provisions set forth herein. All provisions of
this Article XI shall be subject to Section 11.12.

            SECTION 11.02 Liquidation, Dissolution, Bankruptcy. Upon any payment
or distribution of the assets of the Issuers to creditors upon a total or
partial liquidation or a total or partial dissolution of the Issuers or in a
bankruptcy, reorganization, insolvency, receivership or similar proceeding
relating to the Issuers or their property:

            (1) holders of Specified Senior Indebtedness of the Issuers shall be
      entitled to receive payment in full in cash or cash equivalents of such
      Specified Senior Indebtedness before Securityholders shall be entitled to
      receive any payment of principal of, interest on or any other amount
      payable in respect of the Securities; and

            (2) until such Specified Senior Indebtedness is paid in full in cash
      or cash equivalents, any distribution to which Securityholders would be
      entitled but for this Article XI shall be made to holders of such
      Specified Senior Indebtedness as their interests may appear, except that
      Securityholders may receive shares of stock and any debt securities that
      are subordinated to such Specified Senior Indebtedness, and to any debt
      securities received by holders of Specified Senior Indebtedness of the
      Issuers, to at least the same extent as the Securities are subordinated to
      Specified Senior Indebtedness of the Issuers.

            SECTION 11.03 Default on Specified Senior Indebtedness of the
Issuers. The Issuers may not pay the principal of, interest on or any other
amount payable in respect of the Securities or make any deposit pursuant to
Section 8.01 and may not repurchase, redeem or defease any Securities
(collectively, "pay the Securities") if (i) any Specified Senior Indebtedness of
the Issuers is not paid when due or (ii) any other default on such Specified
Senior Indebtedness occurs and the maturity of such Specified Senior
Indebtedness is accelerated in accordance with its terms unless, in either case,
(x) the default has been cured or waived and any such acceleration 


                                      -76-


has been rescinded or (y) such Specified Senior Indebtedness has been paid in
full; provided, however, that the Issuers may pay the Securities without regard
to the foregoing if the Issuers and the Trustee receive written notice approving
such payment from the Representative of such Specified Senior Indebtedness with
respect to which either of the events set forth in clause (i) or (ii) of this
sentence has occurred and is continuing. During the continuance of any default
(other than a default described in clause (i) or (ii) of the preceding sentence)
with respect to any Specified Senior Indebtedness of the Issuers pursuant to
which the maturity thereof may be accelerated immediately without further notice
(except such notice as may be required to effect such acceleration) or after the
expiration of any applicable grace periods, the Issuers may not pay the
Securities for a period (a "Payment Blockage Period") commencing upon the
receipt by the Issuers and the Trustee of written notice (a "Blockage Notice")
of such default from the Representative of such Specified Senior Indebtedness
specifying an election to effect a Payment Blockage Period and ending 179 days
thereafter (or earlier if such Payment Blockage Period is terminated (i) by
written notice to the Trustee and the Issuers from the Person or Persons who
gave such Blockage Notice, (ii) because the Specified Senior Indebtedness has
been repaid in full or (iii) because the default giving rise to such Blockage
Notice is no longer continuing). Notwithstanding the provisions described in the
immediately preceding sentence (but subject to the provisions contained in the
first sentence of this Section), unless the holders of Specified Senior
Indebtedness of the Issuers or the Representative of such holders shall have
accelerated the maturity of such Specified Senior Indebtedness, the Issuers may
resume payments on the Securities after such Payment Blockage Period. The
Securities shall not be subject to more than one Payment Blockage Period in any
consecutive 360-day period, irrespective of the number of defaults with respect
to Specified Senior Indebtedness of the Issuers during such period. For purposes
of this Section, no default or event of default which existed or was continuing
on the date of the commencement of any Payment Blockage Period with respect to
the Specified Senior Indebtedness initiating such Payment Blockage Period shall
be, or be made, the basis of the commencement of a subsequent Payment Blockage
Period by the Representative of such Specified Senior Indebtedness, whether or
not within a period of 360 consecutive days, unless such default or event of
default shall have been cured or waived for a period of not less than 90
consecutive days.

            SECTION 11.04 Acceleration of Payment of Securities. If payment of
the Securities is accelerated because of an Event of Default, the Issuers or the
Trustee shall promptly notify the holders of the Specified Senior Indebtedness
of the Issuers (or their Representative) of the acceleration.

            SECTION 11.05 When Distribution Must Be Paid Over. If a distribution
is made to Securityholders that because of this Article XI should not have been
made to them, the Securityholders who receive the distribution shall hold it in
trust for holders of Specified Senior Indebtedness of the Issuers and pay it
over to them as their interests may appear.

            SECTION 11.06 Subrogation. After all Specified Senior Indebtedness
of the Issuers is paid in full in cash or cash equivalents and until the
Securities are paid in full, the Securityholders shall be subrogated to the
rights of holders of such Specified Senior Indebtedness to receive distributions
applicable to such Specified Senior Indebtedness. A distribution made under this
Article XI to holders of such Specified Senior Indebtedness which otherwise
would 


                                      -77-


have been made to Securityholders is not, as between the Issuers and
Securityholders, a payment by the Issuers on such Specified Senior Indebtedness.

            SECTION 11.07 Relative Rights. This Article XI defines the relative
rights of Securityholders and holders of Specified Senior Indebtedness of the
Issuers. Nothing in this Indenture shall:

            (1) impair, as between the Issuers and Securityholders, the
      obligation of the Issuers, which is absolute and unconditional, to pay
      principal of and interest on the Securities in accordance with their
      terms; or

            (2) prevent the Trustee or any Securityholder from exercising its
      available remedies upon a Default or Event of Default, subject to the
      rights of holders of Specified Senior Indebtedness of the Issuers to
      receive distributions otherwise payable to Securityholders.

            SECTION 11.08 Subordination May Not Be Impaired by Issuers. No right
of any holder of Specified Senior Indebtedness of the Issuers to enforce the
subordination of the Indebtedness evidenced by the Securities shall be impaired
by any act or failure to act by the Issuers or by its failure to comply with
this Indenture.

            SECTION 11.09 Rights of Trustee and Paying Agent. Notwithstanding
Section 11.03, the Trustee or Paying Agent may continue to make payments on the
Securities and shall not be charged with knowledge of the existence of facts
that would prohibit the making of any such payments unless, not less than two
Business Days prior to the date of such payment, a Trust Officer of the Trustee
receives notice satisfactory to it that payments may not be made under this
Article XI. The Issuers, the Registrar or co-registrar, the Paying Agent, a
Representative or a holder of Senior Indebtedness may give the notice; provided,
however, that, if the holders of Specified Senior Indebtedness of the Issuers
have a Representative, only the Representative may give the notice.

            The Trustee in its individual or any other capacity may hold
Specified Senior Indebtedness of the Issuers with the same rights it would have
if it were not Trustee. The Registrar and co-registrar and the Paying Agent may
do the same with like rights. The Trustee shall be entitled to all the rights
set forth in this Article XI with respect to any Specified Senior Indebtedness
of the Issuers which may at any time be held by it, to the same extent as any
other holder of such Specified Senior Indebtedness; and nothing in Article 7
shall deprive the Trustee of any of its rights as such holder. Nothing in this
Article XI shall apply to claims of, or payments to, the Trustee under or
pursuant to Section 7.07.

            SECTION 11.10 Distribution or Notice to Representative. Whenever a
distribution is to be made or a notice given to holders of Specified Senior
Indebtedness of the Issuers, the distribution may be made and the notice given
to their Representative (if any).

            SECTION 11.11 Article XI Not to Prevent Events of Default or Limit
Right to Accelerate. The failure to make a payment pursuant to the Securities by
reason of any provision 


                                      -78-


in this Article XI shall not be construed as preventing the occurrence of a
Default or Event of Default. Nothing in this Article XI shall have any effect on
the right of the Securityholders or the Trustee to accelerate the maturity of
the Securities.

            SECTION 11.12 Trust Moneys Not Subordinated. Notwithstanding
anything contained herein to the contrary, payments from money or the proceeds
of U.S. Government Obligations held in trust under Article 8 hereunder by the
Trustee for the payment of principal of and interest on the Securities shall not
be subordinated to the prior payment of any Specified Senior Indebtedness or
subject to the restrictions set forth in this Article XI, and none of the
Securityholders shall be obligated to pay over any such amount to the Issuers or
any holder of Specified Senior Indebtedness of the Issuers or any other creditor
of the Issuers.

            SECTION 11.13 Trustee Entitled to Rely. Upon any payment or
distribution pursuant to this Article XI, the Trustee and the Securityholders
shall be entitled to rely (i) upon any order or decree of a court of competent
jurisdiction in which any proceedings of the nature referred to in Section 11.02
are pending, (ii) upon a certificate of the liquidating trustee or agent or
other Person making such payment or distribution to the Trustee or to the
Securityholders or (iii) upon the Representative for the holders of Specified
Senior Indebtedness of the Issuers for the purpose of ascertaining the Persons
entitled to participate in such payment or distribution, the holders of such
Specified Senior Indebtedness, the amount thereof or payable thereon, the amount
or amounts paid or distributed thereon and all other facts pertinent thereto or
to this Article XI. In the event that the Trustee determines, in good faith,
that evidence is required with respect to the right of any Person as a holder of
Specified Senior Indebtedness of the Issuers to participate in any payment or
distribution pursuant to this Article XI, the Trustee may request such Person to
furnish evidence to the reasonable satisfaction of the Trustee as to the amount
of such Specified Senior Indebtedness held by such Person, the extent to which
such Person is entitled to participate in such payment or distribution and other
facts pertinent to the rights of such Person under this Article XI and, if such
evidence is not furnished, the Trustee may defer any payment to such Person
pending judicial determination as to the right of such Person to receive such
payment. The provisions of Sections 7.01 and 7.02 shall be applicable to all
actions or omissions of actions by the Trustee pursuant to this Article XI.

            SECTION 11.14 Trustee to Effectuate Subordination. Each
Securityholder by accepting a Security authorizes and directs the Trustee on his
behalf to take such action as may be necessary or appropriate to acknowledge or
effectuate the subordination between the Securityholders and the holders of
Specified Senior Indebtedness of the Issuers as provided in this Article XI and
appoints the Trustee as attorney-in-fact for any and all such purposes.

            SECTION 11.15 Trustee Not Fiduciary for Holders of Specified Senior
Indebtedness. The Trustee shall not be deemed to owe any fiduciary duty to the
holders of Specified Senior Indebtedness and shall not be liable to any such
holders if it shall mistakenly pay over or distribute to Securityholders or the
Issuers or any other Person, money or assets to which any holders of Specified
Senior Indebtedness of the Issuers shall be entitled by virtue of this Article
XI or otherwise.


                                      -79-


            SECTION 11.16 Reliance by Holders of Specified Senior Indebtedness
on Subordination Provisions. Each Securityholder by accepting a Security
acknowledges and agrees that the foregoing subordination provisions are, and are
intended to be, an inducement and a consideration to each holder of any
Specified Senior Indebtedness of the Issuers, whether such Specified Senior
Indebtedness was created or acquired before or after the issuance of the
Securities, to acquire and continue to hold, or to continue to hold, such
Specified Senior Indebtedness and such holder of such Specified Senior
Indebtedness shall be deemed conclusively to have relied on such subordination
provisions in acquiring and continuing to hold, or in continuing to hold, such
Specified Senior Indebtedness.

                                   ARTICLE XII

                        Guaranty of Securities, Indemnity

            SECTION 12.01 Guaranty. (a) The Company, as principal obligor and
not merely as surety, hereby irrevocably and unconditionally guarantees to each
Holder of a Security authenticated and delivered by the Trustee and to the
Trustee and its successors and assigns, that: (i) principal of, premium, if any,
and interest on the Securities (including any Additional Amounts payable in
respect thereof) will be promptly paid in full when due, subject to any
applicable grace period, whether on the relevant Stated Maturity, on an interest
payment date, by acceleration, by call for redemption or upon repurchase or
purchase pursuant to Article 3, Sections 4.06, 4.07 or 4.10 or otherwise and
interest on the overdue principal and premium, if any, and purchase price and
interest on any interest, to the extent lawful (in each case Post-Petition
Interest relating to the Issuers or the Company), on the Securities and all
other amounts payable under the Securities and obligations of the Issuers to the
Holders or the Trustee hereunder or thereunder will be promptly paid in full or
performed when the same shall become due and payable, whether on the relevant
maturity date, upon acceleration, by call for redemption, upon repurchase or
purchase pursuant to a Change of Control, any Asset Disposition, any repurchase
of Securities pursuant to Section 4.07 or otherwise, all in accordance with the
terms hereof and thereof; and (ii) in case of any extension of time of payment
or renewal of any Securities or of any 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, subject to any applicable grace period, whether at
maturity, on an interest payment date, by acceleration, required repurchase or
otherwise. All payments under this Guaranty shall be made in United States
Dollars.

            (b) All payments made by the Company under the Guaranty with respect
to the Securities will be made in United States Dollars free and clear of and
without withholding or deduction for or on account of any present or future
Taxes imposed or levied by or on behalf of Thailand (or any political
subdivision or taxing authority of Thailand), unless the Company is required to
withhold or deduct such Taxes by law or by the interpretation or administration
thereof. In the event that payments under the Guaranty are subject to
withholding or deduction for or on account of any present or future Taxes
imposed by Thailand (or any political subdivision or taxing authority of or in
Thailand), the Company shall pay Additional Amounts in such amounts and to the
extent set forth in Section 4.20(a).


                                      -80-


            (c) The Company hereby agrees that its obligations hereunder shall
be unconditional and irrevocable, irrespective of the validity, regularity or
enforceability of the Securities or this Indenture or the obligations of the
Issuers hereunder or thereunder, the absence of any action to enforce the same,
any waiver or consent by any Holder of the Securities with respect to any
provisions hereof or thereof, the recovery of any judgment against the Issuers,
any action to enforce the same or any other circumstance which might otherwise
constitute a legal or equitable discharge or defense of a guarantor.

            (d) The Company hereby waives diligence, presentment, demand of
payment, filing of claims with a court in the event of insolvency or bankruptcy
of the Issuers, any right to require a proceeding first against the Issuers, any
right to pursue or exhaust its legal or equitable remedies against the Issuers
(including any right which the Company may have to require the seizure and sale
of the assets of the Issuers to satisfy the outstanding principal of, interest
on or any other amounts payable under each Note prior to recourse against the
Company or its assets), protest, notice and all demands whatsoever and covenants
that the Guaranty will not be discharged except by complete performance of the
obligations contained in the Securities and this Indenture. If any
Securityholder or the Trustee is required by any court or otherwise to return to
the Issuers, the Company, or any custodian, trustee, liquidator or other similar
official acting in relation to the Issuers or the Company any amount paid by the
Issuers or the Company to the Trustee or such Securityholder, the Guaranty to
the extent theretofore discharged, shall be reinstated in full force and effect.

            (e) The Company agrees that, as between the Company, on the one
hand, and the Holders and the Trustee, on the other hand, (x) the maturity of
the obligations guaranteed hereby may be accelerated as provided in Article VI
for the purposes of the Guaranty, notwithstanding any stay, injunction or other
prohibition preventing such acceleration in respect of the obligations
guaranteed hereby, and (y) in the event of any acceleration of such obligations
as provided in Section 6.02, such obligations (whether or not then due and
payable) shall forthwith become due and payable by the Company for the purposes
of the Guaranty.

            (f) The Company also agrees, to pay any and all costs and expenses
(including reasonable attorneys' fees and expenses) incurred by the Trustee or
any Holders in enforcing any rights under the Guaranty.

            (g) The Company hereby waives, in favor of the Holders and the
Trustee, any and all of its rights, protections, privileges and defenses
provided by law to a guarantor and in particular any applicable provisions of
the Thailand Civil Code and:

            (i) waives any right of set-off which the Company may have against
      the registered Holder of a Security in respect of any amounts which are or
      may become payable by the registered Holder of a Security to the Issuers;

            (ii) agrees that the Company is still under an obligation to make
      payment to the registered Holder of a Security or the Trustee under this
      Guaranty upon demand by the registered Holder of a Security even though
      the registered Holder of a Security has not made any demand upon the
      Issuers, the Trustee or the Collateral Agent or taken any steps 


                                      -81-


      or proceedings against the Issuers to seize and sell its assets or
      property to recover the secured indebtedness or, if such steps or
      proceedings are taken, the registered Holder of a Security is otherwise
      unable to satisfy the Indebtedness under this Indenture from such assets
      or property;

            (iii) relinquishes any right or privilege which it may have to
      demand from any court that the registered Holder of a Security or the
      Trustee should split or apportion the Indebtedness under this Indenture
      either proportionately or otherwise against the Company and any other
      person who has given any Guaranty or other security to the registered
      Holder of a Security in respect of the Indebtedness under this Indenture;

            (iv) agrees that (subject to the other provisions of this Guaranty)
      the Company shall not be entitled to claim from the Issuers any
      compensation or release in respect of the obligations and liabilities of
      the Company under this Guaranty in circumstances where the Company has not
      made any actual payment under this Guaranty;

            (v) agrees that the Company shall not make use of any of the
      exceptions or defenses against the registered Holder of a Security or the
      Trustee which are or may be available to the Issuers and which concerns
      the Indebtedness under this Indenture;

            (vi) agrees that the Company shall still be bound by and liable
      under this Guaranty even though due to the fault of the registered Holder
      of a Security or the Trustee, the Company can no longer be subrogated to
      the rights, security interests and other privileges of the registered
      Holder of a Security against the Issuers;

            (vii) agrees that the Company shall not have the right to demand the
      Issuers to repay the Indebtedness under this Indenture to the registered
      Holder of a Security, or to release the Company from its liability under
      this Guaranty in circumstances where the registered Holder of a Security
      has granted any time or other indulgence to the Issuers.

            SECTION 12.02 Indemnity. (a) The Company hereby irrevocably and
unconditionally agrees as a primary obligor to indemnify (the "Indemnity") fully
the Holders of the Securities and the Trustee for and against any amounts owed
by the Issuers in respect of the Securities and this Indenture that otherwise
would be payable under the Guaranty in the event that the Guaranty is for any
reason deemed to be unenforceable. Except as otherwise indicated herein or as
the context may otherwise require, all references herein and in the Securities
shall be deemed to constitute references to the Indemnity.

            (b) The obligations of the Company assumed under this Indenture with
respect to the Indemnity are independent undertakings and constitute the
Company's own debt and obligation, as meant by or in accordance with any
applicable provisions of the Thailand Civil Code, separate from the Guaranty
contained in Section 12.01, not accessory to any of the Security Documents, and
with respect to which Indemnity of any such provision of the Thailand Civil Code
does not therefore apply.


                                      -82-


            SECTION 12.03 Representation and Warranty. The Company hereby
represents and warrants that all acts, conditions and things required to be done
and performed and to have happened precedent to the creation and issuance of the
Guaranty and the Indemnity, and to constitute the same legal, valid and binding
obligations of the Company enforceable in accordance with their respective
terms, have been done and performed and have happened in compliance with all
applicable laws.

            SECTION 12.04 Waiver of Subrogation. The Company hereby irrevocably
waives any claim or other rights which it may now or hereafter acquire against
the Issuers that arise from the existence, payment, performance or enforcement
of the Company's obligations under the Guaranty, the Indemnity and this
Indenture, including, without limitation, any right of subrogation,
reimbursement, exoneration, indemnification, any right to participate in any
claim or remedy of any Holder of Securities against the Issuers whether or not
such claim, remedy or right arises in equity, or under contract, statute or
common law, including, without limitation, the right to take or receive from the
Issuers, directly or indirectly, in cash or other property or by setoff or in
any other manner, payment or security on account of such claim or other rights.
If any amount shall be paid to the Company in violation of the preceding
sentence and the Securities shall not have been paid in full, such amount shall
have been deemed to have been paid to the Company for the benefit of, and held
in trust for the benefit of, the Holders of the Securities, and shall forthwith
be paid to the Trustee for the benefit of such Holders to be credited and
applied upon the Securities, whether matured or unmatured, in accordance with
the terms of this Indenture. The Company acknowledges that it will receive
direct and indirect benefits from the financing arrangements contemplated by
this Indenture and that the waiver set forth in this Section 12.04 is knowingly
made in contemplation of such benefits.

                                  ARTICLE XIII

                            Subordination of Guaranty

            SECTION 13.01 Agreement to Subordinate. The Company agrees, and each
Securityholder by accepting a Security agrees, that the obligations of the
Company under the Guaranty (the "Obligations") are subordinated in right of
payment, to the extent and in the manner provided in this Article XIII, to the
prior payment in full in cash or cash equivalents of all Specified Senior
Indebtedness of the Company and that the subordination is for the benefit of and
enforceable by the holders of such Specified Senior Indebtedness. The
Obligations of the Company shall in all respects rank pari passu with all other
Senior Indebtedness of the Company and only Indebtedness of the Company which is
Specified Senior Indebtedness shall rank senior to the Guaranty in accordance
with the provisions set forth herein.

            SECTION 13.02 Liquidation, Dissolution, Bankruptcy. Upon any payment
or distribution of the assets of the Company to creditors upon a total or
partial liquidation or a total or partial dissolution of the Company or in a
bankruptcy, reorganization, insolvency, receivership or similar proceeding
relating to the Company or its property:

            (1) holders of Specified Senior Indebtedness of the Company shall be
      entitled to receive payment in full of such Specified Senior Indebtedness
      in cash or cash 


                                      -83-


      equivalents before Securityholders shall be entitled to receive any
      payment pursuant to any Obligations of the Company; and

            (2) until the Specified Senior Indebtedness of the Company is paid
      in full in cash or cash equivalents, any distribution to which
      Securityholders would be entitled but for this Article XIII shall be made
      to holders of such Specified Senior Indebtedness of the Company as their
      interests may appear, except that Securityholders may receive shares of
      stock and any debt securities of the Company that are subordinated to
      Specified Senior Indebtedness, and to any debt securities received by
      holders of Specified Senior Indebtedness of the Company, to at least the
      same extent as the Obligations of the Company are subordinated to
      Specified Senior Indebtedness of the Company.

            SECTION 13.03 Default on Specified Senior Indebtedness of the
Company. The Company may not make any payment pursuant to any of its Obligations
or repurchase, redeem or otherwise retire or defease any Securities or other
Obligations (collectively, "pay its Guaranty") if (i) any Specified Senior
Indebtedness of the Company is not paid when due or (ii) any other default on
Specified Senior Indebtedness of the Company occurs and the maturity of such
Specified Senior Indebtedness is accelerated in accordance with its terms
unless, in either case, (x) the default has been cured or waived and any such
acceleration has been rescinded or (y) such Specified Senior Indebtedness has
been paid in full; provided, however, that the Company may pay its Guaranty
without regard to the foregoing if the Company and the Trustee receive written
notice approving such payment from the Representative of the Specified Senior
Indebtedness with respect to which either of the events set forth in clause (i)
or (ii) of this sentence has occurred and is continuing. During the continuance
of any default (other than a default described in clause (i) or (ii) of the
preceding sentence) with respect to any Specified Senior Indebtedness of the
Company pursuant to which the maturity thereof may be accelerated immediately
without further notice (except such notice as may be required to effect such
acceleration) or the expiration of any applicable grace periods, the Company may
not pay its Guaranty for a period (a "Guaranty Payment Blockage Period")
commencing upon the receipt by the Trustee (with a copy to the Company) of
written notice (a "Guaranty Blockage Notice") of such default from the
Representative of the holders of such Specified Senior Indebtedness specifying
an election to effect a Guaranty Payment Blockage Period and ending 179 days
thereafter (or earlier if such Guaranty Payment Blockage Period is terminated
(i) by written notice to the Trustee and the Company from the Person or Persons
who gave such Guaranty Blockage Notice, (ii) because the default giving rise to
such Guaranty Blockage Notice is no longer continuing or (iii) because such
Specified Senior Indebtedness has been repaid in full). Notwithstanding the
provisions described in the immediately preceding sentence (but subject to the
provisions contained in the first sentence of this Section), unless the holders
of Specified Senior Indebtedness giving such Guaranty Blockage Notice or the
Representative of such holders shall have accelerated the maturity of such
Specified Senior Indebtedness, the Company shall resume payments pursuant to its
Obligations after the end of such Guaranty Payment Blockage Period. The Guaranty
shall not be subject to more than one Guaranty Payment Blockage Period in any
consecutive 360-day period, irrespective of the number of defaults with respect
to Specified Senior Indebtedness of the Company during such period. For purposes
of this Section, no default or event of default which existed or was continuing
on the date of the commencement of any Guaranty Payment Blockage Period with
respect to the Specified Senior Indebtedness initiating such Guaranty Payment


                                      -84-


Blockage Period shall be, or be made, the basis of the commencement of a
subsequent Guaranty Payment Blockage Period by the Representative of such
Specified Senior Indebtedness, whether or not within a period of 360 consecutive
days, unless such default or event of default shall have been cured or waived
for a period of not less than 90 consecutive days.

            SECTION 13.04 Demand for Payment. If a demand for payment (upon
receipt of the requisite information from the Company) is made on the Company
pursuant to Article XIII, the Company or the Trustee shall promptly notify the
holders of Specified Senior Indebtedness (or their Representatives) of the
Company of such demand.

            SECTION 13.05 When Distribution Must Be Paid Over. If a distribution
is made to Securityholders that because of this Article XIII should not have
been made to them, the Securityholders who receive the distribution shall hold
it in trust for holders of the relevant Specified Senior Indebtedness and pay it
over to them or their Representative as their interests may appear.

            SECTION 13.06 Subrogation. After all Specified Senior Indebtedness
of the Company is paid in full and until the Securities are paid in full,
Securityholders shall be subrogated to the rights of holders of such Specified
Senior Indebtedness to receive distributions applicable to Specified Senior
Indebtedness. A distribution made under this Article XIII to holders of such
Specified Senior Indebtedness which otherwise would have been made to
Securityholders is not, as between the Company and Securityholders, a payment by
the Company on such Specified Senior Indebtedness.

            SECTION 13.07 Relative Rights. This Article XIII defines the
relative rights of Securityholders and holders of Specified Senior Indebtedness
of the Company. Nothing in this Indenture shall:

            (1) impair, as between the Company and Securityholders, the
      obligation of the Company, which is absolute and unconditional, to pay its
      Obligations to the extent set forth in Article XIII; or

            (2) prevent the Trustee or any Securityholder from exercising its
      available remedies upon a default by the Company under its Obligations,
      subject to the rights of holders of Specified Senior Indebtedness of the
      Company to receive distributions otherwise payable to Securityholders.

            SECTION 13.08 Subordination May Not Be Impaired by the Company. No
right of any holder of Specified Senior Indebtedness of the Company to enforce
the subordination of the Obligations of the Company shall be impaired by any act
or failure to act by the Company or by its failure to comply with this
Indenture.

            SECTION 13.09 Rights of Trustee and Paying Agent. Notwithstanding
Section 13.03, the Trustee or Paying Agent may continue to make payments
pursuant to the Guaranty and shall not be charged with knowledge of the
existence of facts that would prohibit the making of any such payments unless,
not less than two Business Days prior to the date of such payment, a 


                                      -85-


Trust Officer of the Trustee receives written notice satisfactory to it that
payments may not be made under this Article XIII. The Company, the Trustee, the
Registrar or co-registrar, the Paying Agent, a Representative or a holder of
Specified Senior Indebtedness of the Company may give the notice; provided,
however, that, if an issue of Specified Senior Indebtedness of the Company has a
Representative, only the Representative may give the notice.

            The Trustee in its individual or any other capacity may hold
Specified Senior Indebtedness of the Company with the same rights it would have
if it were not Trustee. The Registrar and co-registrar and the Paying Agent may
do the same with like rights. The Trustee shall be entitled to all the rights
set forth in this Article 12 with respect to any Specified Senior Indebtedness
of the Company which may at any time be held by it, to the same extent as any
other holder of such Specified Senior Indebtedness of the Company; and nothing
in Article 7 shall deprive the Trustee of any of its rights as such holder.
Nothing in this Article 12 shall apply to claims of, or payments to, the Trustee
under or pursuant to Section 7.07.

            SECTION 13.10 Distribution or Notice to Representative. Whenever a
distribution is to be made or a notice given to holders of Specified Senior
Indebtedness of the Company, the distribution may be made and the notice given
to their Representative (if any).

            SECTION 13.11 Article XIII Not to Prevent Defaults Under the
Guaranty or Limit Right to Demand Payment. The failure to make a payment
pursuant to the Guaranty by reason of any provision in this Article shall not be
construed as preventing the occurrence of a default under the Guaranty. Nothing
in this Article XIII shall have any effect on the right of the Securityholders
or the Trustee to make a demand for payment on the Company pursuant to Article
XIII.

            SECTION 13.12 Trustee Entitled to Rely. Upon any payment or
distribution pursuant to this Article XIII, the Trustee and the Securityholders
shall be entitled to rely (i) upon any order or decree of a court of competent
jurisdiction in which any proceedings of the nature referred to in Section 13.02
are pending, (ii) upon a certificate of the liquidating trustee or agent or
other Person making such payment or distribution to the Trustee or to the
Securityholders or (iii) upon the Representative for the holders of Specified
Senior Indebtedness of the Company for the purpose of ascertaining the Persons
entitled to participate in such payment or distribution, the holders of such
Senior Indebtedness and other indebtedness of the Company, the amount thereof or
payable thereon, the amount or amounts paid or distributed thereon and all other
facts pertinent thereto or to this Article XIII. In the event that the Trustee
determines, in good faith, that evidence is required with respect to the right
of any Person as a holder of Specified Senior Indebtedness of the Company to
participate in any payment or distribution pursuant to this Article XIII, the
Trustee may request such Person to furnish evidence to the reasonable
satisfaction of the Trustee as to the amount of Specified Senior Indebtedness of
the Company held by such Person, the extent to which such Person is entitled to
participate in such payment or distribution and other facts pertinent to the
rights of such Person under this Article XIII, and, if such evidence is not
furnished, the Trustee may defer any payment to such Person pending judicial
determination as to the right of such Person to receive such payment. The
provisions of Sections 7.01 and 7.02 shall be applicable to all actions or
omissions of actions by the Trustee pursuant to this Article 12.


                                      -86-


            SECTION 13.13 Trustee to Effectuate Subordination. Each
Securityholder by accepting a Security authorizes and directs the Trustee on his
behalf to take such action as may be necessary or appropriate to acknowledge or
effectuate the subordination between the Securityholders and the holders of
Specified Senior Indebtedness of the Company as provided in this Article XIII
and appoints the Trustee as attorney-in-fact for any and all such purposes.

            SECTION 13.14 Trustee Not Fiduciary for Holders of Senior
Indebtedness of the Company. The Trustee shall not be deemed to owe any
fiduciary duty to the holders of Specified Senior Indebtedness of the Company
and shall not be liable to any such holders if it shall mistakenly pay over or
distribute to Securityholders or any other Person, money or assets to which any
holders of such Specified Senior Indebtedness shall be entitled by virtue of
this Article XIII or otherwise.

            SECTION 13.15 Reliance by Holders of Specified Senior Indebtedness
of the Company on Subordination Provisions. Each Securityholder by accepting a
Security acknowledges and agrees that the foregoing subordination provisions
are, and are intended to be, an inducement and a consideration to each holder of
any Specified Senior Indebtedness of the Company, whether such Specified Senior
Indebtedness was created or acquired before or after the issuance of the
Security, to acquire and continue to hold, or to continue to hold, such
Specified Senior Indebtedness and such holder of Specified Senior Indebtedness
shall be deemed conclusively to have relied on such subordination provisions in
acquiring and continuing to hold, or in continuing to hold, such Specified
Senior Indebtedness.

                                   ARTICLE XIV

                                  Miscellaneous

            SECTION 14.01 Trust Indenture Act Controls. If any provision of this
Indenture limits, qualifies or conflicts with another provision which is
required to be included in this Indenture by the TIA, the required provision
shall control.

            SECTION 14.02 Notices. Any notice or communication shall be in
writing and delivered in person or mailed by first-class mail addressed as
follows:

            (a) if to the Issuers:

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

            Any notice or communication mailed to a Securityholder shall be
mailed to the Securityholder at the Securityholder's address as it appears on
the registration books of the Registrar and shall be sufficiently given if so
mailed within the time prescribed.

            Failure to mail a notice or communication to a Securityholder or any
defect in it shall not affect its sufficiency with respect to other
Securityholders. If a notice or communication is mailed in the manner provided
above, it is duly given, whether or not the addressee receives it.

            SECTION 14.03 Communication by Holders with Other Holders.
Securityholders may communicate pursuant to TIA ss. 312(b) with other
Securityholders with respect to their rights under this Indenture or the
Securities. The Issuers, the Trustee, the Registrar and anyone else shall have
the protection of TIA ss. 312(c).

            SECTION 14.04 Certificate and Opinion as to Conditions Precedent.
Upon any request or application by the Issuers to the Trustee to take or refrain
