      substituted as a party to that Project Document in place of the Assignor
      by the assignment under this Agreement to either of them of the rights,
      title, interest and obligations of the Assignor under the relevant Project

      Agent or the Designee, as the case may be.

      done pursuant to Clause 2.1 of this Agreement) (and until such time as
      such Transfer Notice is rescinded in accordance with the terms of the
      Security Sharing Agreement), the Collateral Agent or, as the case may be,
      any Designee, may, with respect to any Project Document:


                                                                          Page 5


      (a)   exercise fully any rights and/or perform any obligations of the
            Assignor under such Project Document in all respects as though

            available to it by law or otherwise as transferee of all or part of
            the Assignor's rights, and obligations under each Project Document,
            which are transferred pursuant to this Agreement and the Transfer
            Notice.

      in addition to, independent of and without prejudice to, and shall not be

      the Trustees, or, as the case may be, the Debenture Trustee (as a second
      priority lien) for the due payment, performance and discharge by the
      Assignor of the Obligations.

5.2   This Agreement and the assignments and transfer herein contained is a
      continuing security and shall remain in full force and effect
      notwithstanding the liquidation, bankruptcy or other incapacity of the

      change in the constitution thereof or any or all indebtedness by whatever
      reason (other than by full performance and discharge of the Obligations)
      or other matter or thing whatever.

5.3   If after the date of this Agreement:

      (a)   any settlement or discharge of any or all of the Obligations of the
            Assignor is nullified for any reason whatsoever; and/or

      (b)   an order or judgment is made against the Thai Lenders, the Trustees
            or, as the case may be, the Debenture Trustee or the holders of the
            Notes or the Debentures under Section 237 of the Civil and
            Commercial Code of Thailand (or any modification or re-enactment
            thereof) or under any of Sections 113, 114 and 115 of the Bankruptcy
            Act of Thailand (or any modification or re-enactment thereof)
            directing Thai Lenders, the Trustee or, as the case may be, the
            Debenture Trustee, to pay any sum received or held by it from the
            Assignor or any other person to settle all or part of the debt of

      shall be recoverable from the Assignor on demand.

      or remedies preclude any further or other exercise of such rights, power
      or remedies or the exercise of any other of such rights, powers or
      remedies.

Attention:  Tracy Shellabarger

Dear Sirs:

We refer to the Shareholders' Agreement dated 12 March 1998 between Nakornthai
Strip Mill Public Company Limited (the "Assignor") and yourselves (the "Project
Document").

We hereby give you notice that pursuant to the Conditional Assignment of Project
Documents made between the Assignor, the Thai Lenders, the Trustees, the
Debenture Trustee and the Collateral Agent (each as defined therein) dated 12
March 1998 (the "Conditional Assignment") the Assignor conditionally assigned
all rights, title and interest in and to the Project Document and conditionally
transferred all of its obligations under the Project Document to the Collateral
Agent for the benefit of the Thai Lenders, holders of the Notes and the holders
of Debentures, and agreed that when such conditional assignment becomes
effective, the Thai Lenders, the holders of the Notes and the holders of
Debentures may substitute the Collateral Agent or its Designee as a party to the
Project Document in the place of the Assignor.

This substitution shall become effective and binding upon giving a Transfer
Notice (and until such time as such Transfer Notice is rescinded in accordance
with the terms of the Security Sharing Agreement) to you confirming that the
conditional assignment and transfer by way of novation has become effective (the
"Transfer and Novation").

Upon the Transfer and Novation the Collateral Agent or the Designee, as the case
may be, shall acquire all rights, title and interest in the Project Document
identical to those of the Assignor and shall assume obligations toward you
identical to those obligations owed by the Assignor to you under the Project
Document. Upon the Transfer and Novation, the Assignor shall cease to be
entitled to exercise such rights, title and interest but shall undertake to
remain, jointly and severally with the Collateral Agent or the Designee, liable
to perform such obligations. After delivery of such Transfer Notice all
references in the Project Document to the Assignor shall be deemed as references
to the Collateral Agent or the Designee, as the case may be.

We hereby confirm that you may rely conclusively upon any Transfer Notice, when
duty issued and delivered to you and that you shall not be concerned to inquire
whether any Event of Default (as defined in the Bank Credit Facility, the
Indentures and the Debenture Indenture, as the case 


                                                                         Page 12


may be) has happened upon which any of the powers, authority and discretion
conferred upon the Collateral Agent by or pursuant to the Conditional Assignment
in relation to the rights, title and interests under and in respect of the
Project Document or any part thereof is or may be exercisable by the Collateral
Agent or otherwise as to the appropriateness of acts purporting or intended to
be in exercise of any such powers.

This notice may not be revoked without the consent of the Thai Lenders, the
Trustees and the Debenture Trustee.

For the avoidance of doubt, references in this notice to the Project Document
shall be construed as references to the Project Document as the same may have
been or may from time to time be amended, novated or supplemented and shall
include any document which is supplemental to, is expressed to be related to or
is entered into pursuant to or in accordance with the terms of the Project
Document. Except as otherwise provided herein, all words and expressions in this
notice shall have the same respective meanings as described in the Conditional
Assignment.

Please acknowledge receipt of this notice and confirm your agreement to the
terms hereof and to the Conditional Assignment in the form of Acknowledgment
attached hereto (the "Acknowledgment") by duly executing and returning one copy
of the Acknowledgment to the Collateral Agent at The Chase Manhattan Bank,
Bubhajit Building, 20 North Sathorn Road, Bangkok 10500 and another copy to the
Assignor.

This notice and the Acknowledgment shall be governed by and construed in
accordance with the laws of the Kingdom of Thailand.

Attention: David Stickler

Dear Sirs:

We refer to the Management Agreement dated 12 March 1998 between Nakornthai
Strip Mill Public Company Limited (the "Assignor") and yourselves on behalf of
NSM Management Co. LLC (the "Project Document").

We hereby give you notice that pursuant to the Conditional Assignment of Project
Documents made between the Assignor, the Thai Lenders, the Trustees, the
Debenture Trustee and the Collateral Agent (each as defined therein) dated 12
March 1998 (the "Conditional Assignment") the Assignor conditionally assigned
all rights, title and interest in and to the Project Document and conditionally
transferred all of its obligations under the Project Document to the Collateral
Agent for the benefit of the Thai Lenders, holders of the Notes and the holders
of the Debentures, and agreed that when such conditional assignment becomes
effective, the Thai Lenders, the holders of the Notes and the holders of the
Debentures may substitute the Collateral Agent or its Designee as a party to the
Project Document in the place of the Assignor.

This substitution shall become effective and binding upon giving a Transfer
Notice (and until such time as such Transfer Notice is rescinded in accordance
with the terms of the Security Sharing Agreement) to you confirming that the
conditional assignment and transfer by way of novation has become effective (the
"Transfer and Novation").

Upon the Transfer and Novation the Collateral Agent or the Designee, as the case
may be, shall acquire all rights, title and interest in the Project Document
identical to those of the Assignor and shall assume obligations toward you
identical to those obligations owed by the Assignor to you under the Project

to perform such obligations. After delivery of such Transfer Notice all
references in the Project Document to the Assignor shall be deemed as references
to the Collateral Agent or the Designee, as the case may be.


                                                                         Page 22


We hereby confirm that you may rely conclusively upon any Transfer Notice, when
duly issued and delivered to you and that you shall not be concerned to inquire
whether any Event of Default (as defined in the Bank Credit Facility, the
Indentures and the Debenture Indenture, as the case may be) has happened upon
which any of the powers, authority and discretion conferred upon the Collateral
Agent by or pursuant to the Conditional Assignment in relation to the rights,
title and interests under and in respect of the Project Document or any part
thereof is or may be exercisable by the Collateral Agent or otherwise as to the
appropriateness of acts purporting or intended to be in exercise of any such
powers.

This notice may not be revoked without the consent of the Thai Lenders, the
Trustees and the Debenture Trustee.

For the avoidance of doubt, references in this notice to the Project Document
shall be construed as references to the Project Document as the same may have
been or may from time to time be amended, novated or supplemented and shall
include any document which is supplemental to, is expressed to be related to or
is entered into pursuant to or in accordance with the terms of the Project
Document. Except as otherwise provided herein, all words and expressions in this
notice shall have the same respective meanings as described in the Conditional
Assignment.

Please acknowledge receipt of this notice and confirm your agreement to the
terms hereof and to the Conditional Assignment in the form of Acknowledgment
attached hereto (the "Acknowledgment") by duly executing and returning one copy

Attention:  Mr. Chamni Janchai

Dear Sirs:

We refer to the Shareholders' Agreement dated 12 March 1998 between Nakornthai
Strip Mill Public Company Limited (the "Assignor") and yourselves (the "Project
Document").

We hereby give you notice that pursuant to the Conditional Assignment of Project
Documents made between the Assignor, the Thai Lenders, the Trustees, the
Debenture Trustee and the Collateral Agent (each as defined therein) dated 12
March 1998 (the "Conditional Assignment") the Assignor conditionally assigned
all rights, title and interest in and to the Project Document and conditionally
transferred all of its obligations under the Project Document to the Collateral
Agent for the benefit of the Thai Lenders, holders of the Notes and the holders
of Debentures, and agreed that when such conditional assignment becomes
effective, the Thai Lenders, the holders of the Notes and the holders of
Debentures may substitute the Collateral Agent or its Designee as a party to the
Project Document in the place of the Assignor.

This substitution shall become effective and binding upon giving a Transfer
Notice (and until such time as such Transfer Notice is rescinded in accordance
with the terms of the Security Sharing Agreement) to you confirming that the
conditional assignment and transfer by way of novation has become effective (the
"Transfer and Novation").

Upon the Transfer and Novation the Collateral Agent or the Designee, as the case
may be, shall acquire all rights, title and interest in the Project Document
identical to those of the Assignor and shall assume obligations toward you
identical to those obligations owed by the Assignor to you under the Project
Document. Upon the Transfer and Novation, the Assignor shall cease to be
entitled to exercise such rights, title and interest but shall undertake to
remain, jointly and severally with the Collateral Agent or the Designee, liable
to perform such obligations. After delivery of such Transfer Notice all
references in the Project Document to the Assignor shall be deemed as references
to the Collateral Agent or the Designee, as the case may be. We hereby confirm
that you may rely conclusively upon any Transfer Notice, when duly issued and
delivered to you and that you shall not be concerned to inquire whether any
Event of Default (as defined in the Bank Credit Facility, the Indentures and the
Debenture Indenture, as the case may be) has happened upon which any of the
powers, authority and discretion conferred upon the Collateral Agent by or


                                                                         Page 27


pursuant to the Conditional Assignment in relation to the rights, title and
interests under and in respect of the Project Document or any part thereof is or
may be exercisable by the Collateral Agent or otherwise as to the
appropriateness of acts purporting or intended to be in exercise of any such
powers.

This notice may not be revoked without the consent of the Thai Lenders, the
Trustees and the Debenture Trustee.

For the avoidance of doubt, references in this notice to the Project Document
shall be construed as references to the Project Document as the same may have
been or may from time to time be amended, novated or supplemented and shall
include any document which is supplemental to, is expressed to be related to or
is entered into pursuant to or in accordance with the terms of the Project
Document. Except as otherwise provided herein, all words and expressions in this
notice shall have the same respective meanings as described in the Conditional
Assignment.

Please acknowledge receipt of this notice and confirm your agreement to the
terms hereof and to the Conditional Assignment in the form of Acknowledgment
attached hereto (the "Acknowledgment") by duly executing and returning one copy
of the Acknowledgment to the Collateral Agent at The Chase Manhattan Bank,
Bubhajit Building, 20 North Sathorn Road, Bangkok 10500 and another copy to the
Assignor.

This notice and the Acknowledgment shall be governed by and construed in
accordance with the laws of the Kingdom of Thailand.

            800 Superior Avenue
            Cleveland, OH 44114

Attention:  Mr. David Stickler Managing Director

Dear Sirs:

We refer to the SDI Management Agreement dated 12 March 1998 between Nakornthai
Strip Mill Public Company Limited (the "Assignor") and yourselves
(the "Project Document").

We hereby give you notice that pursuant to the Conditional Assignment of Project
Documents made between the Assignor, the Thai Lenders, the Trustees, the
Debenture Trustee and the Collateral Agent (each as defined therein) dated 12
March 1998 (the "Conditional Assignment") the Assignor conditionally assigned
all rights, title and interest in and to the Project Document and conditionally
transferred all of its obligations under the Project Document to the Collateral
Agent for the benefit of the Thai Lenders, holders of the Notes and the holders
of Debentures, and agreed that when such conditional assignment becomes
effective, the Thai Lenders, the holders of the Notes and the holders of
Debentures may substitute the Collateral Agent or its Designee as a party to the
Project Document in the place of the Assignor.

This substitution shall become effective and binding upon giving a Transfer
Notice (and until such time as such Transfer Notice is rescinded in accordance
with the terms of the Security Sharing Agreement) to you confirming that the
conditional assignment and transfer by way of novation has become effective (the
"Transfer and Novation").

Upon the Transfer and Novation the Collateral Agent or the Designee, as the case
may be, shall acquire all rights, title and interest in the Project Document
identical to those of the Assignor and shall assume obligations toward you
identical to those obligations owed by the Assignor to you under the Project
Document. Upon the Transfer and Novation, the Assignor shall cease to be
entitled to exercise such rights, title and interest but shall undertake to
remain, jointly and severally with the Collateral Agent or the Designee, liable
to perform such obligations. After delivery of such Transfer Notice all
references in the Project Document to the Assignor shall be deemed as references
to the Collateral Agent or the Designee, as the case may be.

We hereby confirm that you may rely conclusively upon any Transfer Notice, when
duly issued and delivered to you and that you shall not be concerned to inquire
whether any Event of Default (as defined in the Bank Credit Facility, the
Indentures and the Debenture Indenture, as the case may be) has happened upon
which any of the powers, authority and discretion conferred upon the Collateral
Agent by or pursuant to the Conditional Assignment in relation to the rights,
title and 


                                                                         Page 44


interests under and in respect of the Project Document or any part thereof is or
may be exercisable by the Collateral Agent or otherwise as to the
appropriateness of acts purporting or intended to be in exercise of any such
powers.

This notice may not be revoked without the consent of the Thai Lenders, the
Trustees and the Debenture Trustee.

For the avoidance of doubt, references in this notice to the Project Document
shall be construed as references to the Project Document as the same may have
been or may from time to time be amended, novated or supplemented and shall
include any document which is supplemental to, is expressed to be related to or
is entered into pursuant to or in accordance with the terms of the Project
Document, Except as otherwise provided herein, all words and expressions in this
notice shall have the same respective meanings as described in the Conditional
Assignment.

Please acknowledge receipt of this notice and confirm agreement to the terms
hereof and to the Conditional Assignment in the form of Acknowledgment attached
hereto (the "Acknowledgment") by duly executing and returning one copy of the
Acknowledgment to the Collateral Agent at The Chase Manhattan Bank, Bubhajit
Building, 20 North Sathorn Road, Bangkok 10500 and another copy to the Assignor.
