   RE:   USS/KOBE - RTI OPCO CONSENTS AND NOTICES REGARDING TRANSTAR, INC.
         AND LAKE TERMINAL RAILROAD - AGREEMENTS ON ATTACHED SCHEDULE

Dear Bob:

         USS/Kobe Steel Company ("USS/Kobe") has decided to combine (the
"Combination") its business of manufacturing and selling hot-rolled and
cold-finished carbon and alloy steel bars (the "Bar Business") with the Bar
Businesses of Republic Engineered Steels, Inc. ("Republic") and Bar Technologies
Inc. ("Bar Tech"). The Combination, which is expected to be completed on August
13, 1999, will result in a new company to be called "Republic Technologies
International, LLC" ("RTI"). Following the Combination, USX Corporation and Kobe
Steel, the current owners of USS/Kobe, are expected to own 30% of RTI and
affiliates of The Blackstone Group and Veritas Capital Management, the current
owners of Republic and Bar Tech, and certain other investors are expected to own
70% of RTI. Prior to the Combination, USS/Kobe's business of the manufacture and
sale of high-quality hot-rolled carbon and alloy seamless tubes will be
transferred to a new company to be owned by USX Corporation and Kobe Steel, Ltd.
The parties are confident that the Combination will be effectuated in a smooth
manner and that their customers, distributors and suppliers will continue to
obtain the same quality services for which they are each well known.

         The Combination requires assignment of the agreements on the attached
schedule ("Agreements") from USS/Kobe to RTI. Upon assignment, RTI will assume
all rights of USS/Kobe and all obligations to Transtar, Inc, The Lake Terminal
Railroad Company, and USS Great Lakes Fleet, Inc. under the Agreements. These
Agreements to RTI's knowledge, constitute all written agreements presently in
effect between USS/Kobe, on the one hand, and Transtar, Inc., The Lake Terminal
Railroad Company or USS Great Lakes Fleet, Inc., on the other. Some of the
Agreements require consent to assignment, while some do not require such
consent. By this letter, USS/Kobe and RTI are seeking Transtar's written
consent, on its behalf and on behalf of The Lake Terminal Railroad Company and
USS Great Lakes Fleet, Inc., as the case may be, to assignments by USS/Kobe to
RTI of the scheduled Agreements which require consent to be transferred, and are
providing notice of the assignment of those Agreements on the attached schedule
which do not require consent to assignment. RTI represents that the relationship
with Transtar, Inc., The Lake Terminal Railroad Company and USS Great Lakes
Fleet, Inc. under

each of the Agreements to be assigned, and the provision of services by The Lake
Terminal Railroad Company and USS Great Lakes Fleet, Inc. under the Agreements,
will not be affected by the Combination inasmuch as RTI will continue to utilize
the services of The Lake Terminal Railroad Company and USS Great Lakes Fleet,
Inc. which these entities have had rights to provide to USS/Kobe under the
Agreements, either directly for its own account or indirectly by arranging for
the use of such services by the successors and assigns of USS/Kobe going
forward, in accordance with the terms of the Agreements. With respect to those
Agreements which are easements, Transtar, on its own behalf and on behalf of The
Lake Terminal Railroad Company, acknowledges and agrees that those easements
were granted for the benefit of the entire USS/Kobe parcel, and after the
Combination the respective portions of the USS/Kobe parcel will each continue to
have full benefit of all the existing easements, which will be shared by RTI and
an affiliate of USS/Kobe. We would appreciate it if you would execute and return
the enclosed copy of this letter evidencing such consent and confirmation in the
self-addressed envelope provided at your earliest possible convenience.

         If you have any questions regarding this matter, please contact me at
(216) 348-5432.

                                     Sincerely,

                                     /s/ Paul N. Edwards

                                     Paul N. Edwards, Counsel to RTI

CONSENTED TO AND CONFIRMED:

REPUBLIC TECHNOLOGIES                TRANSTAR, INC. on behalf of itself
INTERNATIONAL, LLC                   and The Lake Terminal Railroad Company
                                     and USS Great Lakes Fleet, Inc.
