   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

                                 TRANSTAR, INC.

                       SAVINGS PLAN FOR SALARIED EMPLOYEES
               (As Amended and Restated Effective January 1, 1989)

         The Transtar, Inc. Savings Plan for Salaried Employees shall be amended
effective January 1, 2000 as follows:

1.       Section 4.2 shall be amended to read as follows:

         NON-PARTICIPATING EMPLOYEE. Each other Employee shall become eligible
         to participate in the Plan on the day an Employee completes six (6)
         months of service as described in Section 3.1 or 3.4, whichever is
         applicable.

2.       Section 5.9 subsection (a) shall be amended to read as follows:

         a)       Subject to Article IX, an Eligible Employee may elect to have
                  the Employers pay on his behalf into the Plan during each
                  payroll period, through a reduction in his compensation, at
                  least one percent (1%) of his compensation (before such
                  contribution) for such payroll period and additional amounts
                  in one-half percent (1/2%) increments, but not more than ten
                  percent (10%) of his compensation (taking into account amounts
                  contributed as Voluntary Employee After-Tax Contributions).
                  Notwithstanding the foregoing, effective for Plan years
                  commencing on or after January 1, 1995, the previous sentence
                  shall be amended by substituting "fifteen percent (15%)" for
                  "ten percent (10%), and effective for Plan years commencing on
                  or after January 1, 2000, the previous sentence shall be
                  amended by substituting "eighteen percent (18%)" for "ten
                  percent (10%)" with respect to any Eligible Employee who was
                  not classified as a Highly Compensated Employee in the Plan
                  year prior to the Plan year for which the Pre-Tax Contribution
                  is made. The amounts so contributed shall constitute such
                  Participant's Pre-Tax Contribution, and shall be one hundred
                  percent (100%) non-forfeitable at all times. No Employer
                  contribution (other than a Matching Contribution to this Plan
                  or any other plan sponsored by the Employees shall be affected
                  by or conditioned upon a Participant's election to make
                  Pre-Tax Contributions. The Employer shall remit such Pre-Tax
                  Contributions to the Plan no later than (90 days after the
                  close of the month in which such contributions were withheld.

                  However, any Participant's election may be reduced (as
                  described in Section 5.9(b) and Article IX) by the Plan
                  Manager as necessary to assure compliance with IRC Sections
