                          FIRST SUPPLEMENTAL INDENTURE

                  This First Supplemental Indenture (this "SUPPLEMENTAL
INDENTURE"), dated as of August 23, 2004, among ISG Chicago Cold Rolling, LLC, a
Delaware limited liability company, ISG Columbus Coatings LLC, a Delaware
limited liability company, ISG Columbus Processing LLC, a Delaware limited
liability company, Hibbing Land Corporation, a Delaware corporation, Pristine
Resources, Inc., a Delaware corporation, Tow Path Valley Business Park
Development Company, a Delaware corporation, Tecumseh Redevelopment Inc., a
Delaware corporation, ISG Weirton Inc., a Delaware corporation, and ISG
Georgetown Inc., a Delaware corporation (each, a "GUARANTEEING SUBSIDIARY", and
collectively, the "GUARANTEEING SUBSIDIARIES"), each, a subsidiary of
International Steel Group Inc., a Delaware corporation (the "COMPANY"), the
Company, the other Guarantors and The Bank of New York, a New York banking
corporation, as trustee under the Indenture referred to below (the "TRUSTEE").
All capitalized terms used herein and not otherwise defined shall have the
meanings ascribed thereto in that certain Indenture (the "INDENTURE"), dated as
of April 14, 2004, among the Company, the Trustee, and the other Guarantors
party thereto (the "OTHER GUARANTORS").

                               W I T N E S S E T H

                  WHEREAS, each of the Company and the Other Guarantors has
heretofore executed and delivered to the Trustee the Indenture, providing for
the issuance of the Notes and have issued the Notes and the Guarantees;

                  WHEREAS, the Guaranteeing Subsidiaries desire to
unconditionally guarantee all of the Company's obligations under the Notes and
the Indenture on the terms and conditions set forth herein and on the Notation
of Guarantee attached hereto as Annex A (the "SUBSIDIARY GUARANTEES"); and

                  WHEREAS, pursuant to clause (4) of Section 9.01 of the
Indenture, the Trustee is authorized to execute and deliver any Supplemental
Indenture that makes any change that would provide any additional rights or
benefits to the Holders of the Notes or that does not adversely affect the legal
rights under the Indenture of any Holder.

                  NOW, THEREFORE, in consideration of the foregoing and for
other good and valuable consideration, the receipt of which is hereby
acknowledged, the parties hereto agree for the equal and ratable benefit of the
Holders of the Notes as follows:

                  1. Agreement to Guarantee. The Guaranteeing Subsidiaries and
the Other Guarantors shall provide an unconditional Guarantee on the terms and
subject to the conditions set forth in the Subsidiary Guarantees and in the
Indenture including but not limited to Article 10 thereof and to endorse the
Notation of Guarantee attached hereto as Annex A.

                  2. No Recourse Against Others. No past, present or future
director, manager, officer, employee, incorporator, organizer, member,
stockholder or agent of the Guaranteeing Subsidiaries or the Other Guarantors,
as such, shall have any liability for any obligations of the Company or any
Guaranteeing Subsidiary under the Notes, any Subsidiary Guarantee, the

<PAGE>

Indenture or this Supplemental Indenture or for any claim based on, in respect
of, or by reason of, such obligations or their creation. Each Holder of the
Notes by accepting a Note waives and releases all such liability. The waiver and
release are part of the consideration for issuance of the Notes. Such waiver may
not be effective to waive liabilities under the federal securities laws and it
is the view of the SEC that such a waiver is against public policy.

                  3. GOVERNING LAW. THIS SUPPLEMENTAL INDENTURE WILL BE GOVERNED
BY AND CONSTRUED IN ACCORDANCE WITH THE LAW OF THE STATE OF NEW YORK 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.

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

                  5. Effect of Headings. The Section headings herein are for
convenience only and shall not affect the construction hereof.

                  6. The Trustee. The Trustee shall not be responsible in any
manner whatsoever for or in respect of the validity or sufficiency of this
Supplemental Indenture or for or in respect of the recitals contained herein,
all of which recitals are made solely by the Guaranteeing Subsidiaries and the
Company.
