            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.

            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 


                                                                              36


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 or
Additional Amounts, if any, 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.

            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 


                                                                              37


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 


                                                                              38


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 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 cancelation 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. 


                                                                              39


            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. Cancelation. The Issuers at any time may deliver
Securities to the Trustee for cancelation. 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 cancelation. The
Trustee and no one else shall cancel all Securities surrendered for registration
of transfer, exchange, payment or cancelation and shall dispose of canceled
Securities in accordance with its customary procedures unless otherwise directed
by written direction of an Officer of the Issuers. The Issuers may not issue new
Securities to replace Securities it has redeemed, paid or delivered to the
Trustee for cancelation. 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 


                                                                              40


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. 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 Note 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
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 Depositary and its Agent Members, the
operation 


                                                                              41


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 


                                                                              42


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. A Global Security may not be exchanged for a Definitive
Security other than as provided in 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 


                                                                              43


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 a U.S. Global Security wishes at any time after the
expiration of the Restricted Period to transfer such interest to a Person who

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 


                                                                              44


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

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.

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.

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

            (6) Exchanges of U.S. Global Security for Regulation S Global

                                                                              46


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

            (9) Other Exchanges. In the event that an Initial Global Security or
any portion thereof is exchanged for Initial Securities in definitive form

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

            (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 


                                                                              47


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

            SECTION 2.15. Allocation of Purchase Price. Based on the Company's
estimate of the relative fair market values of the Initial Securities and the
warrants issued in conjunction with the Initial Securities (the "Warrants"), the
Issuers and the Trustee (on behalf of the Securityholders) agree to treat for
U.S. federal income tax purposes $955.70 of each $1,000 of principal amount of
the Initial Securities as allocable to the Initial Securities (which amount the
Company will treat as the issue price of such Securities for U.S. federal income
tax purposes) and $44.30 as allocable to the Warrants.


                                   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


                                                                              48


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 fewer than
all the Securities are to be redeemed, the Trustee shall select the Securities
to be redeemed by lot; provided, however, that if a partial redemption is made
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 $1,000. Securities and portions
of them the Trustee selects shall be in amounts of $1,000 or a whole multiple of
$1,000. 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;


                                                                              49


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

            (5) if fewer than all the outstanding Securities are to be redeemed,
      the certificate numbers and principal amounts of the particular Securities
      to be redeemed;

            (6) that, unless the Issuers default in making such redemption
      payment, interest on Securities (or portion thereof) called for redemption
      ceases to accrue on and after the redemption date;

            (7) the paragraph of the Securities pursuant to which the Securities
      called for redemption are being redeemed;

            (8) the CUSIP number, if any, printed on the Securities being
      redeemed; and

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

            At the Issuers' request, the Trustee shall give the notice of
redemption in the Issuers' name and at the Issuers' expense. In such event, the
Issuers shall provide the Trustee with the information required by this Section
at least 40 days (unless a shorter period shall be acceptable to the Trustee)
prior to the redemption date.

            SECTION 3.04. Effect of Notice of Redemption. Once notice of
redemption is mailed, Securities called for redemption become due and payable on
the redemption date and at the redemption price stated in the notice. Upon
surrender to the Paying Agent, such Securities shall be paid at the redemption
price stated in the notice, plus accrued interest, if any, to the redemption
date; provided that installments of interest due on an interest payment date
that is on or prior to the redemption date shall be payable to the
Securityholder of the redeemed Securities registered on the relevant record
date. Failure to give notice or any defect in the notice to any Holder shall not
affect the validity of the notice to any other Holder.

            SECTION 3.05. Deposit of Redemption Price. Prior to 10:00 A.M., New
York City time, on the Business Day immediately preceding the redemption date,
the Issuers shall deposit with the Paying Agent money sufficient to pay the
redemption price of and accrued interest on all Securities


                                                                              50


to be redeemed on the redemption date other than Securities or portions of
Securities called for redemption that have been delivered by the Issuers to the
Trustee for cancelation.

            SECTION 3.06. Securities Redeemed in Part. Upon surrender of a
Security that is redeemed in part, the Issuers shall execute and the Trustee
shall authenticate for the Holder (at the Issuers' expense) a new Security equal
in principal amount to the unredeemed portion of the Security surrendered.

            SECTION 3.07. Optional Redemption. (a) Except as set forth in the
next two paragraphs, the Securities may not be redeemed prior to February 1,
2003. On and after that date, the Issuers may redeem the Securities in whole at
any time or in part from time to time at the following redemption prices
(expressed in percentages of principal amount at maturity), plus accrued
interest to the redemption date (subject to the right of Holders of record on
the relevant record date to receive interest due on the relevant Interest
Payment Date), if redeemed during the 12-month period beginning on or after
February 1 of the years set forth below:

                                                              Redemption       
Period                                                          Price          
- ------                                                        ----------
                                                                               
2003 ...................................................      106.1250%        
2004 ...................................................      104.0417         
2005 ...................................................      103.0625
2006 and thereafter ....................................      100.0000

            (b) Notwithstanding the foregoing, at any time prior to February 1,
2001, the Company may redeem in the aggregate up to 35% of the original
aggregate principal amount at maturity of Securities with the net cash proceeds
of one or more Public Equity Offerings, at a redemption price (expressed as a
percentage of principal amount at maturity thereof) of 112.25% plus accrued
interest, if any, to the redemption date (subject to the right of Holders of
record on the relevant record date to receive interest due on the relevant
Interest Payment Date); provided, however, that after any such redemption the
aggregate principal amount at maturity of the Securities outstanding must equal
or exceed $132,000,000.

            (c) The Securities may be redeemed at the option of the Issuers, in
whole but not in part, or paid in full but not in part prior to maturity at the
option of the Company, upon not less than 30 nor more than 60 days' notice


                                                                              51


given as provided in Section 3.03, at any time at 103% of the Accreted Value
thereof, 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 (or any political subdivision or taxing authority of either
jurisdiction) and (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;
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 


                                                                              52


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.


                                   ARTICLE IV

      does not exceed U.S.$20 million.

            (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

sole discretion, will classify such item of Indebtedness at the time of its
Incurrence and shall only be required to include the amount and type of such
Indebtedness in one of the above clauses, and (ii) an item of Indebtedness may

Issuers or the Company will, nor will the Company permit any Restricted
Subsidiary to, directly or indirectly:

      payment on or in respect of its Capital Stock (including dividends or
      distributions of the Capital Stock of any Restricted Subsidiary), or make

      substantially concurrent issue and sale for cash (other than to a
      Restricted Subsidiary) of other Capital Stock (other than Disqualified
      Stock) of the Company; provided that the Net Cash Proceeds from the
      issuance of such shares of 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 or acquisitions shall be
      excluded from the calculation of the amount of Restricted Payments;

            (iii) any repurchase, redemption, defeasance, retirement or
      acquisition for value or payment of principal of any Subordinated
      Indebtedness in exchange for, or out of the net proceeds of, a

      refinancing, acquisition for value or payment of principal of any
      Subordinated Indebtedness (other than Disqualified Stock) or Pari Passu
      Indebtedness (a "refinancing") through the issuance of new Subordinated
      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

      Securities, and purchase all Securities tendered, in such Stage III
      Tender.

            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 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.


                                                                              59

            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

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

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


                                                                              60


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 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 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 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
$1,000 of principal amount, at the applicable 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


                                                                              61


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
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 cancelation 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 


                                                                              62


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 $1,000, 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.

Offshore Reserve Account to undertake an offer to purchase Securities (and, at
the Company's election, Senior Notes and Debentures) pro rata at 100% of the
Accreted Value thereof on the date of purchase, plus accrued and unpaid interest
and Additional Amounts, if any, thereon ("Stage III Tender").

            (b) The Issuers will be required to conduct a Stage III Tender and
to purchase tendered Securities in


                                                                              63

Restricted Subsidiary to issue any Capital Stock (other than to the Issuers or
the Company or any Wholly Owned Restricted Subsidiary) or (ii) any Person (other
than the Issuers or the Company or a Wholly Owned Restricted Subsidiary) to

Company or any Restricted Subsidiary, except upon the sale of all of the
outstanding Capital Stock of such Restricted Subsidiary owned by the Issuers or
the Company or another Restricted Subsidiary and the designation of such
Subsidiary as an Unrestricted Subsidiary; provided, however, that the Issuers or
the Company or a Restricted Subsidiary may issue or sell common stock of a
Restricted Subsidiary to a Person that is not an Affiliate of the Company so
long as, on or prior to the consummation of such issuance or sale, such
Restricted Subsidiary issues and delivers a supplemental indenture to the
Indentures providing for the guarantee of the Securities, which guarantee shall
be a senior obligation of such Restricted Subsidiary.

            SECTION 4.09. Limitation on Dividends and Other Payment Restrictions
Affecting Restricted Subsidiaries. Neither the Issuers or the Company will, and
the Company will not permit any of its Restricted Subsidiaries to, directly or
indirectly, create or otherwise cause or permit to exist or become effective any
encumbrance or restriction on the ability of any Restricted Subsidiary to (a)
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
Investment in the Issuers or the Company or (d) transfer any of its properties
or assets to the Issuers or the Company or any Restricted Subsidiary, except (i)
any encumbrance or restriction pursuant to or in connection with the Bank Credit
Facility or the Securities as in effect on the Issue Date, (ii) any encumbrance
or restriction, with respect to a Restricted Subsidiary that is not a Restricted

Restricted Subsidiary and (iv) any encumbrance or restriction existing under 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

the Holders than those under or pursuant to the agreement evidencing such
Refinancing Indebtedness so extended, renewed, refinanced or replaced.

            SECTION 4.10. Change of Control. (a) Upon the occurrence of a Change
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
cash equal to 101% of the Accreted Value thereof on the date of purchase, plus
accrued and unpaid interest and Additional Amounts, if any, to date of
repurchase (subject to the right of Holders of record on the relevant record

      Section, that a Holder must follow in order to have its Securities

Company (an "Affiliate Transaction") unless: (a) the terms of such Affiliate

or on account of any present or future taxes, levies, duties, fees, assessments
or other governmental charges of whatever nature ("Taxes") imposed, levied,
collected or 


                                                                              68


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,
payable or due but for the existence of any present or former connection between
the holder (or the beneficial owner of, or person ultimately entitled to obtain
an interest in, such Securities) and the Cayman Islands or Thailand, as the case
may be, other than the mere holding of the Securities; (ii) which would not have
been imposed, payable or due if the Securities are held in definitive registered
form ("Definitive Registered Securities") and the presentation of Definitive
Registered Securities for 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.


                                                                              69


            (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.

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


                                                                              70


penalties) payable in the Cayman Islands or in Thailand (or any political
subdivision or taxing authority of either jurisdiction) and in the United States
in respect of the creation, issue, offering, execution or enforcement of the
Securities, the Guaranty or any documentation with respect thereto.

            SECTION 4.21. Maintenance of Office or Agency. (a) The Issuers shall
maintain in the Borough of Manhattan, in the City of New York, an office or
agency (which may be an office of the Trustee or an Affiliate of the Trustee,
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 obligations 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
office or agency.

            (c) The Issuers hereby designate the Corporate Trust Office of the
Trustee as one such office or agency of the Company in accordance with Section
2.03.

            SECTION 4.22. Stay, Extension and Usury Laws. Each of the Issuers
and the Company covenants (to the extent it may lawfully do so) that it shall
not at any time insist upon, plead or in any manner whatsoever claim or take the
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


                                                                              71


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.

            SECTION 4.23. Insurance. The Company shall as soon as practicable
after the Issue Date obtain, and thereafter at all times maintain in full force
and effect insurance in such amounts, covering such risks and liabilities and
with such deductibles or self-insured retentions as are in accordance with
normal industry practice. The Company shall furnish when obtained and annually
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.

            SECTION 4.24. Compliance with Statutes. The Company shall, and shall
cause each Subsidiary to, comply with all applicable statutes, regulations and
orders of, and all applicable restrictions imposed by, all governmental bodies,
Thailand or foreign, in respect of the conduct of its business and the ownership
of its property other than those the non-compliance with which would not
reasonably be expected to have a material adverse effect on the condition
(financial or otherwise), results of operations, business or prospects of the
Company and its Subsidiaries taken as a whole.

            SECTION 4.25. Corporate Existence. Subject to Section 5.01, the
Company and the Issuers shall do or cause to be done all things necessary to
preserve and keep in full force and effect their corporate existence, in
accordance with their respective organizational documents (as the same may be
amended from time to time) and the rights (charter and statutory), licenses and
franchises of the Company and the Issuers.

            SECTION 4.26. Independent Engineer. Not later than the 90th day
following the Issue Date, the Company shall have hired (and thereafter shall at
all times retain) the Independent Engineer to perform the duties set forth
herein together with such other duties as the Company and such Independent
Engineer may agree.

            SECTION 4.27. Securities Cash Flow Sweep. No later than the
fifteenth day following the last day of each fiscal quarter of the Company (as
the Company's fiscal year is in effect on the Issue Date), the Company shall
deposit


                                                                              72


into the Notes Net Fund Account an amount equal to the Cash Flow Sweep Amount.

            SECTION 4.28. Payment of Taxes. The Company will pay or discharge or
cause to be paid or discharged, before the same shall become delinquent, (i) all
material taxes, assessments and governmental charges levied or imposed upon the
Company or the Issuers or upon the income, profits or property of the Company or
the Issuers; provided, however, that the Company shall not be required to pay or
discharge or cause to be paid or discharged any such tax, assessment, charge or
claim whose amount, applicability or validity is being contested in good faith
by appropriate proceedings, and against which adequate reserves are being
maintained.

            SECTION 4.29 Intercompany Notes and Capital Contributions. (a) On
the Issue Date, the Company shall issue an intercompany note or notes to the
Issuers obligating the Company to make payments in respect of such intercompany
note or notes on any date and in the same amount that any payment (whether a
payment of principal when due at Stated Maturity, upon optional redemption, upon
required repurchase, upon declaration or otherwise or a payment in respect of
any interest) is due on the Securities; provided, however, if after the Issue
Date the Issuers and the Company determine in good faith that such an
intercompany note obligation will result in a material adverse tax consequence
to the Issuers or the Company, the Issuers and the Company may cancel such
intercompany note obligation and the Company shall thereafter comply with clause
(b) below.

            (b) In the event that at any time the intercompany note referenced
in the preceding sentence has been canceled or otherwise declared inoperative or
unenforceable, then on or prior to any Interest Payment Date in respect of any
Security, or any date upon which any payment of principal of any Security is
required to be made when due at its Stated Maturity, upon optional redemption,
upon required repurchase, upon declaration or otherwise, the Company shall make
a cash contribution to NSM Cayman in the amount of such interest or principal
payment, as the case may be.

consolidate with or merge with or into, or convey, transfer or lease all or
substantially all its 


                                                                              73

the laws of the United States of America, any state thereof or the District of
Columbia or Thailand, and the Successor Company (if not the Company) shall
expressly assume, by indenture supplemental to this Indenture, executed and

such transaction as having been Incurred by the Successor Company at the time of
such transaction), no Default or Event of Default shall have occurred and be
continuing (or would result therefrom); (iii) immediately after giving effect to
such transaction on a pro forma basis (and treating any Indebtedness which

transaction), the Successor Company would be able to incur an additional
U.S.$1.00 of Indebtedness pursuant to the first paragraph of Section 4.03; (iv)
immediately after giving effect to such transaction on a pro forma basis (and
treating any Indebtedness which becomes an obligation of the Successor Company
or any Restricted Subsidiary as a result of such transaction as having been
Incurred by the Successor Company or such Restricted Subsidiary at the time of
such transaction), the Successor Company shall have Consolidated Net Worth in an
amount which is not less than the Consolidated Net Worth of the Company
immediately prior to such transaction; (v) the Successor Company shall have
delivered to the Trustee an Opinion of Counsel to the effect that the holders of
the Securities will not recognize income, gain, or loss for United States
Federal income tax purposes as a result of such transaction, and will be subject
to United States Federal income tax on the same amounts and at the same times as
would be the case as if the transaction had not occurred, and there will be no
additional Thai Taxes and no Taxes of any other jurisdiction imposed on any
payments made pursuant to the Securities or the Guaranty; and (vi) each of the
Company and the Issuers shall have delivered to the Trustee an Officers'
Certificate and an Opinion of Counsel, stating that such consolidation, merger,
conveyance, transfer or lease and such supplemental indentures comply with this
Indenture, and this Indenture (including the Guaranty), the Security Sharing
Agreement, the Security Documents, and the Securities remain and will be in full
force and effect against all applicable parties 


                                                                              74


and the Liens with respect to the Collateral (which shall be first priority
perfected Liens unless otherwise contemplated by the Security Documents)
continue in full force and effect.

            The Successor Company shall be the successor to the Company and
shall succeed to, and be substituted for, and may exercise every right and power
of, the Company under this Indenture, but the predecessor Company in the case of
a conveyance, transfer or lease shall not be released from the obligation to pay
the principal of and interest on the Securities.

            The Issuers shall not consolidate or merge with or into any other
Person, or convey, transfer or lease all or substantially all its assets to any
other Person, and all of its outstanding Capital Stock shall at all times be
owned by the Company free and clear of all Liens (other than Liens securing the
Securities, the Senior Notes and the Debentures).


                                   ARTICLE VI

                             Defaults and Remedies

            SECTION 6.01. Events of Default. Each of the following constitutes

            (d) the failure by the Issuers or the Company to comply for 30 days
      after notice with any of their respective obligations under Article IV
      (other than Section 4.29 and other than a failure to purchase Securities
      pursuant to Section 4.06, 4.07 or 4.10, which shall constitute an Event of

      (b) or (c) above;

            (e) the failure by the Issuers or the Company to comply for 60 days

      million (or its foreign currency equivalent at the time) and such default
      shall not have been cured or such acceleration rescinded after a 10-day
      period;

            (h) the Company, the Issuers or any Subsidiary pursuant to or within
      the meaning of any Bankruptcy Law:

                  (i) commences a voluntary case;

                  (ii) consents to the entry of an order for relief against it
            in an involuntary case;

                  (iii) consents to the appointment of a Custodian of it or for

            (i) a court of competent jurisdiction enters an order or decree

                                                                              76


                  (ii) appoints a Custodian of the Company, the Issuers or any
            Subsidiary or for any substantial part of its property; or

                  (iii) orders the winding up or liquidation of the Company, the
            Issuers or any Subsidiary;

            (j) any judgment or decree for the payment of money in excess of
      U.S.$5 million (or its foreign currency equivalent at the time) (to the
      extent not covered by insurance) is rendered against the Company, the
      Issuers or any Subsidiary and such judgment or decree shall remain
      undischarged or unstayed for a period of 60 days after such judgment
      becomes final and nonappealable (the "judgment default provision");

            (k) any Account or amount therein is not maintained as required or
      any drawing under or deposit into any Account is not made when required to
      be made and in any such case such failure continues unremedied for five
      Business Days (or, in the case of a failure to fund or maintain any
      required amount in, or to make a drawing under, the Notes DSR Account, 30

            (l) the Security Documents shall cease to grant the holders any of

      of any insurance proceeds the Mill is abandoned in whole or in substantial
      part or is destroyed or made permanently inoperable in whole or in
      substantial part (the "abandonment provision").

            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 


                                                                              77


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, 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 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.


                                                                              78


            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.

            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 Past Defaults. The Holders of a majority in
principal amount of the Securities 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 Holders of a majority in
principal amount of the outstanding Securities 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;


                                                                              79


            (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 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 


                                                                              80


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; and

            THIRD: 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 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 


                                                                              81


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 wilful 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.


                                                                              82


            (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 wilful
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 


                                                                              83


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.

            (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.


                                                                              84


            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
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 


                                                                              85


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 wilful 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 Note 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 


                                                                              86


in such event being referred to herein as the retiring Trustee), the Issuers
shall promptly appoint a successor Trustee (subject to the preceding paragraph).

            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 


                                                                              87


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.


                                  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 cancelation 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 


                                                                              88


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 only to the Company and its
Subsidiaries other than 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.

            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;


                                                                              89


            (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 


                                                                              90


      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.

            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
jointly and severally shall 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 


                                                                              91


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;

            (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 


                                                                              92


      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 Holders of at least a majority in principal amount of the Securities then
outstanding. 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;

            (6) impair the right of any 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


                                                                              93


            (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.


                                                                              94


            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 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 


                                                                              95


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 equal and ratable with the rights
that may be created in favor of the creditors under the Bank Credit Facility and
prior to the rights that may be created in favor of the holders of the
Debentures.

            (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 X. 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 X 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,


                                                                              96


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).

            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 


                                                                              97


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 subor-


                                                                              98


      dinated 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 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 


                                                                              99


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 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 


                                                                             100


      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).


                                                                             101


            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 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 


                                                                             102


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.

            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


                                                                             103


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 including
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).

            (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


                                                                             104


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 Security 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:


                                                                             105


            (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 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 


                                                                             106


      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.

            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 


                                                                             107


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


                                                                             108


            (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 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 of the Company, 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 


                                                                             109


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 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 


                                                                             110


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 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; 


                                                                             111


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


                                                                             112


7.02 shall be applicable to all actions or omissions of actions by the Trustee
pursuant to this Article 12.

            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

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

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

            Authorized Officer


                                                                               5


                   [FORM OF REVERSE SIDE OF INITIAL SECURITY]

               12 1/4% Senior Subordinated Mortgage Note Due 2008

1. Interest

            NSM Steel (Delaware), Inc., a company organized under the laws of
Delaware, and NSM Steel Company, Ltd., a company organized under the laws of the
Cayman Islands (such companies, and their successors and assigns under the
Indenture hereinafter referred to, being herein called the "Issuers"), promise
to pay interest on the principal amount of this Security at the rate per annum
shown above. The Issuers will pay interest semiannually on February 1 and August
1 of each year. Interest on the Securities will accrue from the most recent date
to which interest has been paid or, if no interest has been paid, from March 12,
1998. Interest will be computed on the basis of a 360-day year of twelve 30-day
months. The Issuers shall pay interest on overdue principal at the rate borne by
the Securities plus 1% per annum, and they shall pay interest on overdue
installments of interest at the same rate to the extent lawful.

            The Issuers and the Company will use their best efforts to have the
Exchange Offer Registration Statement or, if applicable, the Shelf Registration
Statement (each a "Registration Statement") declared effective by the Commission
as promptly as practicable after the filing thereof. If (i) the Exchange Offer
Registration Statement is not filed within 90 days following the Issue Date,
additional interest shall accrue on the Securities over and above the stated
interest at a rate of .50% per annum commencing on the 91st day after the Issue
Date and such additional interest rate shall increase by .50% per annum on the
first day of each 90 day period thereafter; (ii) the Exchange Offer Registration
Statement is not declared effective within 180 days following the Issue Date or,
if applicable, the Shelf Registration Statement is not declared effective within
245 days following the Issue Date, additional interest shall accrue on the
Securities over and above the stated interest at a rate of .50% per annum
commencing on the 181st day after the Issue Date and such additional interest
rate shall increase by .50% per annum on the first day of each 90 day period
thereafter; or (iii) (A) the Issuers have not exchanged all Securities validly
tendered in accordance with the terms of the Exchange Offer on or prior to 210
days after the Issue Date or (B) the Exchange Offer Registration Statement
ceases to be effective at any time prior to the time that the Exchange Offer is


                                                                               6


consummated or (C) if applicable, the Shelf Registration Statement has been
declared effective and such Shelf Registration Statement ceases to be effective
at any time prior to the second anniversary of the Issue Date (unless all the
Securities have been sold thereunder), then additional interest shall accrue on
the Securities over and above the stated interest at a rate of .50% per annum
commencing on (x) the 211th day after the Issue Date with respect to the
Securities validly tendered and not exchanged by the Company, in the case of (A)
above, or (y) the day the Exchange Offer Registration Statement ceases to be
effective or usable for its intended purpose in the case of (B) above, or (z)
the day such Shelf Registration Statement ceases to be effective in the case of
(C) above and such additional interest rate shall increase by .50% per annum on
the first day of each 90 day period thereafter; provided, however, that the
additional interest rate on the Securities may not exceed in the aggregate 1.5%
per annum (each such event referred to in clauses (i) through (iii), a
"Registration Default"). All accrued additional interest shall be paid to
Holders in the same manner as interest payments on the Securities on semi-annual
payment dates which correspond to interest payment dates for the Securities.
Following the cure of all Registration Defaults, the accrual of additional
interest will cease. The Trustee shall have no responsibility with respect to
the determination of the amount of any such additional interest. For purposes of
the foregoing, "Registrable Securities" means (i) each Initial Security until
the date on which such Initial Security has been exchanged for a freely
transferable Exchange Security in the Exchange Offer, (ii) each Initial Security
until the date on which such Initial Security has been effectively registered
under the Securities Act and disposed of in accordance with the Shelf
Registration Statement or (iii) each Initial Security until the date on which
such Initial Security is distributed to the public pursuant to Rule 144 under
the Securities Act or is saleable pursuant to Rule 144(k) under the Securities
Act.

2. Method of Payment

            The Issuers will pay interest on the Securities (except defaulted
interest) to the Persons who are registered Holders of Securities at the close
of business on the January 15 or July 15 next preceding the interest payment
date even if Securities are canceled after the record date and on or before the
interest payment date. Holders must surrender Securities to a Paying Agent to
collect principal payments. The Issuers will pay principal and interest in money
of the United States that at the time 


                                                                               7


of payment is legal tender for payment of public and private debts. However, the
Issuers may pay principal and interest by check payable in such money. They may
mail an interest check to a Holder's registered address.

3. Paying Agent and Registrar

            Initially, THE CHASE MANHATTAN BANK, a New York banking corporation
("Trustee"), will act as Paying Agent and Registrar. The Issuers may appoint and
change any Paying Agent, Registrar or co-registrar without notice.

4. Indenture

            The Issuers issued the Securities under an Indenture dated as of
March 1, 1998 (the "Indenture"), among the Issuers, Nakornthai Strip Mill Public
Company Limited (the "Company") and the Trustee. The terms of the Securities
include those stated in the Indenture and those made part of the Indenture by
reference to the Trust Indenture Act of 1939 (15 U.S.C. ss.ss. 77aaa-77bbbb) as
in effect on the date of the Indenture, except as otherwise provided in the
Indenture (the "Act"). Terms defined in the Indenture and not defined herein
have the meanings ascribed thereto in the Indenture. The Securities are subject
to all such terms, and Securityholders are referred to the Indenture and the Act
for a statement of those terms.

            The Securities are secured, senior subordinated obligations of the
Issuers limited to US$203,500,000 aggregate principal amount (subject to Section
2.07 of the Indenture). The Indenture imposes certain limitations on the
Incurrence of Indebtedness by the Issuers and certain of their Subsidiaries, the
payment of dividends on, and redemption of, the Capital Stock of the Issuers and
their Subsidiaries and the redemption of certain subordinated obligations of the
Issuers and their subsidiaries, restricted payments, the creation or existence
of certain Liens, the sale or transfer of assets and Subsidiary stock, the
issuance or sale of Capital Stock of Restricted Subsidiaries, the business
activities and investments of the Issuers and certain of their Subsidiaries,
consolidations, mergers and transfers of all or substantially all the assets of
the Issuers or certain Subsidiaries, and transactions with Affiliates. In
addition, the Indenture limits the ability of the Issuers and certain of their
Subsidiaries to restrict distributions and dividends from Subsidiaries.


                                                                               8


            To secure the due and punctual payment of the principal and
additional interest and interest, if any, on the Securities and all other
amounts payable by the Issuers under the Indenture and the Securities when and
as the same shall be due and payable, whether at maturity, by acceleration or
otherwise, according to the terms of the Securities and the Indenture, the
Company has unconditionally guaranteed the Securities on a senior (other than in
respect of any Specified Senior Indebtedness of the Company) basis pursuant to
the terms of the Indenture.

5. Optional Redemption

            (a) Except as set forth in the two next succeeding paragraphs, the
Securities may not be redeemed prior to February 1, 2003. On and after that
date, the Issuers may redeem the Securities in whole or in part, upon no less
than 30 nor more than 60 days' prior notice, at the following redemption prices
(expressed in percentages of principal amount at maturity), plus accrued
interest, if any, to the redemption date (subject to the right of Holders of
record on the relevant record date to receive interest due on the relevant
Interest Payment Date), if redeemed during the 12-month period commencing on
February 1 of the years set forth below:

            Period                        Percentages
            ------                        -----------

            2003                          106.1250%
            2004                          104.0417%
            2005                          103.0625%
            2006 and thereafter           100.0000%


            (b) At any time prior to February 1, 2001, the Issuers may redeem in
the aggregate up to 35% of the aggregate principal amount at maturity of
Securities with the net proceeds of one or more Public Equity Offerings by the
Issuers, at a redemption price of 112.25% of the principal amount at maturity
thereof at the redemption date plus accrued interest, if any, to the redemption
date (subject to the right of Holders of record on the relevant record date to
receive interest due on the related interest payment date); provided, however,
that after any such redemption the aggregate principal amount at maturity of the
Securities outstanding must equal or exceed US$132,000,000. In order to effect
the foregoing redemption with the proceeds of any Public Equity Offering, the
Issuers must make such redemption not more than 60 days after the consummation
of any such Public Equity Offering.


                                                                               9


            (c) The Securities may be redeemed at the option of the Issuers or
paid in full at the option of the Company, in whole but not in part, upon not
less than 30 nor more than 60 days' notice given as provided in the Indenture,
at any time at 103% of the principal amount thereof, 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 as a result of the imposition
of Taxes imposed by the Cayman Islands or Thailand (or any political subdivision
or taxing authority or 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 any political subdivision or taxing authority of either
jurisdiction); 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 Steel
Company, Ltd. is, or on the next Interest Payment Date would be, required to
deduct or withhold taxes imposed by the Cayman Islands or Thailand (or any
political subdivision or taxing authority of either jurisdiction) and (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; 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 the Guaranty were then due.

            Prior to the publication of the notice of redemption in accordance
with the foregoing, the Issuers or 


                                                                              10


the Company shall deliver to the Trustee an Officers' Certificate stating that
(x) the Issuers or the Company are 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 clause (ii) of the immediately preceding paragraph is
satisfied. Such notice, once delivered by the Issuers or the Company to the
Trustee, will be irrevocable.

6. Notice of Redemption

            Notice of redemption will be mailed at least 30 days but not more
than 60 days before the redemption date to each Holder of Securities to be
redeemed at his registered address. Securities in denominations larger than
US$1,000 may be redeemed in part but only in whole multiples of US$1,000. If
money sufficient to pay the redemption price of and accrued interest on all
Securities (or portions thereof) to be redeemed on the redemption date is
deposited with the Paying Agent on or before the redemption date and certain
other conditions are satisfied, on and after such date interest ceases to accrue
on such Securities (or such portions thereof) called for redemption.

7. Put Provisions

            Upon a Change of Control, any Holder of Securities will have the
right, subject to certain conditions, to cause the Issuers to repurchase all or
any part of the Securities of such Holder at a purchase price in cash equal to
101% of the Accreted Value of the Securities on the date of purchase plus
accrued and unpaid interest and Additional Amounts, if any, to the date of
repurchase (subject to the right of Holders of record on the relevant record
date to receive interest due on the related Interest Payment Date) as provided
in, and subject to the terms of, the Indenture.

8. Additional Amounts

            (a) All payments made by the Issuers under or with respect to the
Securities and by the Company under the Guaranty will be made free and clear of
and without withholding or deduction for or on account of any present or 


                                                                              11


future taxes, levies, duties, fees, assessments or other governmental charges of
whatever nature ("Taxes") imposed, levied, 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 Taxes by law or by the interpretation or administration thereof. If the
Issuers are or the Company is 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, 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 such Holder or 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 or beneficial owner of Securities with respect to any Tax: (i)
which would not have been imposed, payable or due but for the existence of any
present or former connection between such Holder (or the beneficial owner of, or
Person ultimately entitled to obtain an interest in, such Securities) and the
Cayman Islands or Thailand, as the case may be, other than the mere holding of
such Securities; (ii) which would not have been imposed, payable or due if such
Securities had been held in definitive registered form ("Definitive Registered
Securities") and the presentation of Definitive Registered Securities for
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 such
Securities for payment on any date during 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 such Holder or
beneficial owner 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 such Holder or
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 


                                                                              12


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, 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 (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 the Indenture or in this Security
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 the 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.


                                                                              13

            (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 Thailand (or
any political subdivision or taxing authority of either jurisdiction) and in the
United States in respect of the creation, issue, offering, execution or
enforcement of the Securities, the Guaranty or any documentation with respect
thereto.

9. Denominations; Transfer; Exchange

            The Securities are in registered form without coupons in
denominations of US$1,000 and any integral multiple of US$1,000. A Holder may
transfer or exchange Securities in accordance with the Indenture. The Registrar
may require a Holder, among other things, to furnish appropriate endorsements or
transfer documents and to pay any taxes and fees required by law or permitted by
the Indenture. The Registrar need not register the transfer of or exchange any
Securities selected for redemption (except, in the case of a Security to be
redeemed in part, the portion of the Security not to be redeemed) or any
Securities for a period of 15 days before a selection of Securities to be
redeemed or 15 days before an interest payment date.

10. Persons Deemed Owners

            The registered Holder of this Security may be treated as the owner
of it for all purposes.

11. Unclaimed Money

            If money for the payment of principal or interest remains unclaimed
for two years, the Trustee or Paying Agent shall pay the money back to the
Issuers at their written request unless an abandoned property law designates
another Person. After any such payment, Holders entitled to the money must look
only to the Issuers and not to the Trustee for payment.


                                                                              14


12. Discharge and Defeasance

            Subject to certain conditions, the Issuers at any time may terminate
some or all of their obligations under the Securities and the Indenture if the
Issuers deposit with the Trustee money or U.S. Government Obligations for the
payment of principal, premium (if any) and interest on the Securities to
redemption or maturity, as the case may be.

13. Amendment, Waiver

            Subject to certain exceptions set forth in the Indenture, (i) the
Indenture or the Securities may be amended with the written consent of the
Holders of at least a majority in principal amount at maturity of the Securities
then outstanding and (ii) any existing Default and its consequences or
noncompliance with any provisions may be waived with the written consent of the
Holders of a majority in principal amount at maturity of the Securities then
outstanding. Subject to certain exceptions set forth in the Indenture, without
the consent of any Securityholder, the Issuers, the Company and the Trustee may
amend the Indenture (and the Trustee and the Company may amend the Guaranty) or
the Securities to cure any ambiguity, omission, defect or inconsistency, or to
comply with Article 5 of the Indenture, to provide for uncertificated Securities
in addition to or in place of certificated Securities, to add further Guaranties
with respect to the Securities or to further secure the Securities, to add
additional covenants or surrender rights and powers conferred upon the Issuers
or the Company, to comply with any request of the SEC in connection with
qualifying the Indenture under the Act or to make any change that does not
adversely affect the rights of any Securityholder.

14. Defaults and Remedies

            Under the Indenture, Events of Default include (i) a default in any
payment of interest on any Security when due, continued for 30 days, (ii) a
default in the payment of principal of any Security when due at its Stated
Maturity, upon optional redemption, upon required repurchase, upon declaration
or otherwise, (iii) the failure by the Issuers or the Company to comply with its
obligations under Section 5.01 of the Indenture, (iv) the failure (A) by the
Issuers or the Company to comply for 30 days after notice

with any of its obligations under Article 4 of the Indenture or (B) by the
Company or the Issuers or any Restricted Subsidiary to comply for 30 days after

a failure to purchase Securities which shall constitute an Event of Default
under clause (ii) above), other than as described in clause (i), (ii) or (iii)
above, (v) the failure by the Issuers or the Company to comply with other
agreements in the Securities, the Indenture or the Note Guaranty, in certain
cases subject to notice and lapse of time, (vi) the Guaranty ceases to be in
full force and effect (except as contemplated by the terms thereof) or the
Company denies or disaffirms its obligations under the Indenture or the
Guaranty, (vii) the failure by the Company, the Issuers or any Restricted
Subsidiary to pay any Indebtedness within any applicable grace period after
final maturity or the acceleration of any such Indebtedness by the holders
thereof because of a default if the total amount of such Indebtedness unpaid or
accelerated exceeds US$5 million and such default shall not have been cured or
such acceleration rescinded after a 10-day period, (viii) certain events of
bankruptcy, insolvency or reorganization of the Company, the Issuers or any
Subsidiary, (ix) the rendering of any judgment or decree for the payment of
money in excess of US$5 million (to the extent not covered by insurance) against
the Company, the Issuers or a Subsidiary if (A) an enforcement proceeding
thereon is commenced or (B) such judgment or decree remains outstanding for a
period of 60 days following such judgment and is not discharged, waived or
stayed, (x) any Account is not maintained as required or any drawing under any
Account is not made when required to be made and in any such case such failure
continues unremedied for five Business Days (or, in the case of a failure to
maintain any required amount in, or to make a drawing under, the Notes DSR
Account, 30 days), (xi) the Security Documents shall cease to grant the Holders
any of the material collateral or rights purported to be granted thereunder or

Event of Default with respect to the Securities occurs (other than an Event of
Default with respect to the Issuers or the Company pursuant to certain events of
bankruptcy or insolvency) and is continuing, the Trustee or the Holders of at
least 25% in principal amount at maturity of the outstanding Securities may
declare the Accreted Value as of the date on which the Securities first became
due and payable plus accrued and unpaid interest, if any, on all the Securities

            (b) The obligations of the Company under its Guaranty will be
secured equally and ratably by (i) a first mortgage over the land and buildings
comprising the Mill (except for the Co-Gen Facility); (ii) a security interest

purposes of the Security Sharing Agreement in connection with any communications
or other dealings with the Collateral Agent, and the Collateral Agent shall not
be required to accept communications from any party other than the Trustee, with
respect to any request, instruction, direction, approval, consent, agreement or
other instruction of the Holders under the Indenture or the Security Sharing
Agreement.

to it by the Issuers or its Affiliates and may otherwise deal with the Issuers
or its Affiliates with the same rights it would have if it were not Trustee.

17. No Recourse Against Others

            A director, officer, employee or stockholder, as such, of the
Issuers, shall not have any liability for any obligations of the Issuers under
the Securities or the Indenture or for any claim based on, in respect of or by

                   [FORM OF REVERSE SIDE OF INITIAL SECURITY]

               12 1/4% Senior Subordinated Mortgage Note Due 2008

1. Interest

            NSM Steel (Delaware), Inc., a company organized under the laws of
Delaware, and NSM Steel Company, Ltd., a company organized under the laws of the
Cayman Islands (such companies, and their successors and assigns under the
Indenture hereinafter referred to, being herein called the "Issuers"), promise
to pay interest on the principal amount of this Security at the rate per annum
shown above. The Issuers will pay interest semiannually on February 1 and August
1 of each year. Interest on the Securities will accrue from the most recent date
to which interest has been paid or, if no interest has been paid, from March 12,
1998. Interest will be computed on the basis of a 360-day year of twelve 30-day
months. The Issuers shall pay interest on overdue principal at the rate borne by
the Securities plus 1% per annum, and they shall pay interest on overdue
installments of interest at the same rate to the extent lawful.

2. Method of Payment

            The Issuers will pay interest on the Securities (except defaulted
interest) to the Persons who are registered Holders of Securities at the close
of business on the January 15 or July 15 next preceding the interest payment
date even if Securities are canceled after the record date and on or before the
interest payment date. Holders must surrender Securities to a Paying Agent to
collect principal payments. The Issuers will pay principal and interest in money
of the United States that at the time of payment is legal tender for payment of
public and private debts. However, the Issuers may pay principal and interest by
check payable in such money. They may mail an interest check to a Holder's
registered address.

3. Paying Agent and Registrar

            Initially, THE CHASE MANHATTAN BANK, a New York banking corporation
("Trustee"), will act as Paying Agent and Registrar. The Issuers may appoint and
change any Paying Agent, Registrar or co-registrar without notice.


                                                                               5


4. Indenture

            The Issuers issued the Securities under an Indenture dated as of
March 1, 1998 (the "Indenture"), among the Issuers, Nakornthai Strip Mill Public
Company Limited (the "Company") and the Trustee. The terms of the Securities
include those stated in the Indenture and those made part of the Indenture by
reference to the Trust Indenture Act of 1939 (15 U.S.C. ss.ss. 77aaa-77bbbb) as
in effect on the date of the Indenture, except as otherwise provided in the
Indenture (the "Act"). Terms defined in the Indenture and not defined herein
have the meanings ascribed thereto in the Indenture. The Securities are subject
to all such terms, and Securityholders are referred to the Indenture and the Act
for a statement of those terms.

            The Securities are secured, senior subordinated obligations of the
Issuers limited to $203,500,000 aggregate principal amount (subject to Section
2.07 of the Indenture). The Indenture imposes certain limitations on the
Incurrence of Indebtedness by the Issuers and certain of their Subsidiaries, the
payment of dividends on, and redemption of, the Capital Stock of the Issuers and
their Subsidiaries and the redemption of certain subordinated obligations of the
Issuers and their subsidiaries, restricted payments, the creation or existence
of certain Liens, the sale or transfer of assets and Subsidiary stock, the
issuance or sale of Capital Stock of Restricted Subsidiaries, the business
activities and investments of the Issuers and certain of their Subsidiaries,
consolidations, mergers and transfers of all or substantially all the assets of
the Issuers or certain Subsidiaries, and transactions with Affiliates. In
addition, the Indenture limits the ability of the Issuers and certain of their
Subsidiaries to restrict distributions and dividends from Subsidiaries.

            To secure the due and punctual payment of the principal and
interest, if any, on the Securities and all other amounts payable by the Issuers
under the Indenture and the Securities when and as the same shall be due and
payable, whether at maturity, by acceleration or otherwise, according to the
terms of the Securities and the Indenture, the Company has unconditionally
guaranteed the Securities on a senior (other than in respect of any Specified
Senior Indebtedness of the Company) basis pursuant to the terms of the
Indenture.


                                                                               6


5. Optional Redemption

            (a) Except as set forth in the two next succeeding paragraphs, the

date, the Issuers may redeem the Securities in whole or in part, upon no less
than 30 nor more than 60 days' prior notice, at the following redemption prices
(expressed in percentages of principal amount at maturity), plus accrued
interest, if any, to the redemption date (subject to the right of Holders of
record on the relevant record date to receive interest due on the relevant
Interest Payment Date), if redeemed during the 12-month period commencing on
February 1 of the years set forth below:

            Period                        Percentages
            ------                        -----------

            2003                          106.1250%
            2004                          104.0417%
            2005                          103.0625%
            2006 and thereafter           100.0000%


            (b) At any time prior to February 1, 2001, the Issuers may redeem in
the aggregate up to 35% of the aggregate principal amount at maturity of
Securities with the net proceeds of one or more Public Equity Offerings by the
Issuers, at a redemption price of 112.25% of the principal amount at maturity
thereof at the redemption date plus accrued interest, if any, to the redemption
date (subject to the right of Holders of record on the relevant record date to
receive interest due on the related interest payment date); provided, however,
that after any such redemption the aggregate principal amount at maturity of the
Securities outstanding must equal or exceed US$132,000,000. In order to effect
the foregoing redemption with the proceeds of any Public Equity Offering, the
Issuers must make such redemption not more than 60 days after the consummation
of any such Public Equity Offering.

            (c) The Securities may be redeemed at the option of the Issuers or
paid in full at the option of the Company, in whole but not in part, upon not
less than 30 nor more than 60 days' notice given as provided in the Indenture,
at any time at 103% of the principal amount thereof, 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 


                                                                               7


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 as a result of the imposition of Taxes
imposed by the Cayman Islands or Thailand (or any political subdivision or
taxing authority or 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 any political subdivision or taxing authority of either
jurisdiction); 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 Steel
Company, Ltd. is, or on the next Interest Payment Date would be, required to
deduct or withhold taxes imposed by the Cayman Islands or Thailand (or any
political subdivision or taxing authority of either jurisdiction) and (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; 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 the 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 or the Company are 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 clause (ii) of the
immediately preceding paragraph is 


                                                                               8


satisfied. Such notice, once delivered by the Issuers or the Company to the
Trustee, will be irrevocable.

6. Notice of Redemption

            Notice of redemption will be mailed at least 30 days but not more
than 60 days before the redemption date to each Holder of Securities to be
redeemed at his registered address. Securities in denominations larger than
US$1,000 may be redeemed in part but only in whole multiples of US$1,000. If
money sufficient to pay the redemption price of and accrued interest on all
Securities (or portions thereof) to be redeemed on the redemption date is
deposited with the Paying Agent on or before the redemption date and certain
other conditions are satisfied, on and after such date interest ceases to accrue
on such Securities (or such portions thereof) called for redemption.

7. Put Provisions

            Upon a Change of Control, any Holder of Securities will have the
right, subject to certain conditions, to cause the Issuers to repurchase all or
any part of the Securities of such Holder at a purchase price in cash equal to
101% of the Accreted Value of the Securities on the date of purchase plus
accrued and unpaid interest and Additional Amounts, if any, to the date of
repurchase (subject to the right of Holders of record on the relevant record
date to receive interest due on the related Interest Payment Date) as provided
in, and subject to the terms of, the Indenture.

8. Additional Amounts

            (a) All payments made by the Issuers under or with respect to the
Securities and by the Company under the Guaranty will be made free and clear of
and without withholding or deduction for or on account of any present or future
taxes, levies, duties, fees, assessments or other governmental charges of
whatever nature ("Taxes") imposed, levied, 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 Taxes by law or by the interpretation or administration thereof. If the
Issuers are or the Company is 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 


                                                                               9


any payment made under or with respect to the Securities or the Guaranty, 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 such Holder or 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 or
beneficial owner of Securities with respect to any Tax: (i) which would not have
been imposed, payable or due but for the existence of any present or former
connection between such Holder (or the beneficial owner of, or Person ultimately
entitled to obtain an interest in, such Securities) and the Cayman Islands or
Thailand, as the case may be, other than the mere holding of such Securities;
(ii) which would not have been imposed, payable or due if such Securities had
been held in definitive registered form ("Definitive Registered Securities") and
the presentation of Definitive Registered Securities for 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 such Securities for
payment on any date during 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 such Holder or beneficial
owner 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 such Holder or 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 


                                                                              10


withheld from each taxing authority imposing such Taxes. The Issuers or the
Company, as the case may be, will furnish to the Holders, 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 (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 the Indenture or in this Security
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 the 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.

            (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 Thailand (or
any political subdivision or taxing authority of either jurisdiction) and in the
United States in respect of the creation, issue, offering, execution or
enforcement of the Securities, the Guaranty or any documentation with respect
thereto.


                                                                              11


9. Denominations; Transfer; Exchange

            The Securities are in registered form without coupons in
denominations of US$1,000 and any integral multiple of US$1,000. A Holder may
transfer or exchange Securities in accordance with the Indenture. The Registrar
may require a Holder, among other things, to furnish appropriate endorsements or
transfer documents and to pay any taxes and fees required by law or permitted by
the Indenture. The Registrar need not register the transfer of or exchange any
Securities selected for redemption (except, in the case of a Security to be
redeemed in part, the portion of the Security not to be redeemed) or any
Securities for a period of 15 days before a selection of Securities to be
redeemed or 15 days before an interest payment date.

10. Persons Deemed Owners

            The registered Holder of this Security may be treated as the owner
of it for all purposes.

11. Unclaimed Money

            If money for the payment of principal or interest remains unclaimed
for two years, the Trustee or Paying Agent shall pay the money back to the
Issuers at their written request unless an abandoned property law designates
another Person. After any such payment, Holders entitled to the money must look
only to the Issuers and not to the Trustee for payment.

12. Discharge and Defeasance

            Subject to certain conditions, the Issuers at any time may terminate
some or all of their obligations under the Securities and the Indenture if the
Issuers deposit with the Trustee money or U.S. Government Obligations for the
payment of principal, premium (if any) and interest on the Securities to
redemption or maturity, as the case may be.

13. Amendment, Waiver

            Subject to certain exceptions set forth in the Indenture, (i) the
Indenture or the Securities may be amended with the written consent of the
Holders of at least 


                                                                              12


a majority in principal amount at maturity of the Securities then outstanding
and (ii) any existing Default and its consequences or noncompliance with any
provisions may be waived with the written consent of the Holders of a majority
in principal amount at maturity of the Securities then outstanding. Subject to
certain exceptions set forth in the Indenture, without the consent of any
Securityholder, the Issuers, the Company and the Trustee may amend the Indenture
(and the Trustee and the Company may amend the Guaranty) or the Securities to
cure any ambiguity, omission, defect or inconsistency, or to comply with Article
5 of the Indenture, to provide for uncertificated Securities in addition to or
in place of certificated Securities, to add further Guaranties with respect to
the Securities or to further secure the Securities, to add additional covenants
or surrender rights and powers conferred upon the Issuers or the Company, to
comply with any request of the SEC in connection with qualifying the Indenture
under the Act or to make any change that does not adversely affect the rights of
any Securityholder.

14. Defaults and Remedies

            Under the Indenture, Events of Default include (i) a default in any
payment of interest on any Security when due, continued for 30 days, (ii) a
default in the payment of principal of any Security when due at its Stated

or otherwise, (iii) the failure by the Issuers or the Company to comply with its
obligations under Section 5.01 of the Indenture, (iv) the failure (A) by the
Issuers or the Company to comply for 30 days after notice with any of its

disaffirms its obligations under the Indenture or the Guaranty, (vii) the
failure by the Company, the Issuers or any Restricted Subsidiary to pay any
Indebtedness within any applicable grace period after final maturity or the
acceleration of any such Indebtedness by the holders thereof because of a
default if the total amount of 


                                                                              13


such Indebtedness unpaid or accelerated exceeds US$5 million and such default
shall not have been cured or such acceleration rescinded after a 10-day period,
(viii) certain events of bankruptcy, insolvency or reorganization of the
Company, the Issuers or any Subsidiary, (ix) the rendering of any judgment or
decree for the payment of money in excess of US$5 million (to the extent not
covered by insurance) against the Company, the Issuers or a Subsidiary if (A) an
enforcement proceeding thereon is commenced or (B) such judgment or decree
remains outstanding for a period of 60 days following such judgment and is not
discharged, waived or stayed, (x) any Account is not maintained as required or
any drawing under any Account is not made when required to be made and in any
such case such failure continues unremedied for five Business Days (or, in the
case of a failure to maintain any required amount in, or to make a drawing
under, the Notes DSR Account, 30 days), (xi) the Security Documents shall cease
to grant the Holders any of the material collateral or rights purported to be
granted thereunder or (xii) after giving effect to the anticipated receipt and
application of any insurance proceeds, the Mill is abandoned in whole or in
substantial part or is destroyed or made permanently inoperable in whole or in
substantial part. If an Event of Default with respect to the Securities occurs
(other than an Event of Default with respect to the Issuers or the Company
pursuant to certain events of bankruptcy or insolvency) and is continuing, the
Trustee or the Holders of at least 25% in principal amount at maturity of the
outstanding Securities may declare the Accreted Value as of the date on which
the Securities first became due and payable plus 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.

            Securityholders may not enforce the Indenture or the Securities
except as provided in the Indenture. The Trustee may refuse to enforce the
Indenture or the Securities unless it receives reasonable indemnity or security.
Subject to certain limitations, Holders of a majority in principal amount of the
Securities may direct the Trustee in its exercise of any trust or power. The
Trustee may withhold from Securityholders notice of any continuing Default
(except a Default in payment of principal or interest) if it determines that
withholding notice is in the interest of the Holders.


                                                                              14

secured by pledges of the capital stock of NSM Steel (Delaware), Inc.

            (b) The obligations of the Company under its Guaranty will be
secured equally and ratably by (i) a first mortgage over the land and buildings
comprising the Mill (except for the Co-Gen Facility); (ii) a security interest
in all amounts in the Notes DSR Account and Offshore Reserve Account; (iii) a
security interest in all machinery and movable property located at the Mill;

basis, certain existing Indebtedness under the Bank Credit Facility. In
addition, all Collateral will secure, on a second priority basis, the
obligations of the Company in respect of the Debenture Guaranty.

            (c) To secure the due and punctual payment of the obligations of the
Issuers and the Company under the Indenture, the Securities and the Guaranty,
the Issuers and the Company have entered into the Security Documents. The
Issuers and the Trustee hereby acknowledge and agree that the Collateral Agent
holds the Collateral in trust for the benefit of the Holders and other
beneficiaries pursuant to the terms of the Security Sharing Agreement. Each
Holder, by accepting or holding a Security, shall be deemed to have agreed to
all the terms and provisions of the Security Sharing Agreement.

            (d) Each Holder, by accepting a Security, shall be deemed to have
authorized the Trustee to act as the representative of the Holders for the
purposes of the Security Sharing Agreement in connection with any communications
or other dealings with the Collateral Agent, and the Collateral Agent shall not
be required to accept communications from any party other than the Trustee, with
respect to any request, instruction, direction, approval, 


                                                                              15


consent, agreement or other instruction of the Holders under the Indenture or
the Security Sharing Agreement.

16. Trustee Dealings with the Issuers

            Subject to certain limitations imposed by the Act, the Trustee under
the Indenture, in its individual or any other capacity, may become the owner or
pledgee of Securities and may otherwise deal with and collect obligations owed
to it by the Issuers or its Affiliates and may otherwise deal with the Issuers
or its Affiliates with the same rights it would have if it were not Trustee.

17. No Recourse Against Others

            A director, officer, employee or stockholder, as such, of the
Issuers, shall not have any liability for any obligations of the Issuers under
the Securities or the Indenture or for any claim based on, in respect of or by
reason of such obligations or their creation. By accepting a Security, each
Securityholder waives and releases all such liability. The waiver and release
are part of the consideration for the issue of the Securities.

WITH, THE LAWS OF THE STATE OF NEW YORK BUT WITHOUT GIVING EFFECT TO APPLICABLE
PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT THAT THE APPLICATION OF THE LAWS OF
ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY. THE VARIOUS AGREEMENTS CREATING
AND GOVERNING THE COLLATERAL WILL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE
WITH, THE LAWS OF THE STATE OF NEW YORK AND THAILAND.
