                 o        DILLON READ UNDERSTANDS THIS COURSE OF ACTION

                          -       Eliminates management distractions related to
                                  governance, IR, etc.

                          -       Simplifies cash flow and accounting

                          -       If financed properly, can be modestly
                                  accretive to TIN

                          -       Little benefit to valuation for either Company
                                  under current structure

                 o        DILLON READ IS WILLING TO ASSIST TIN IN EVALUATING

OVERVIEW OF PROCESS

         o       DILLON READ EXPECTS THE CONTEMPLATED TRANSACTION WILL BE
                 STRAIGHTFORWARD AND LIKELY COMPLETED IN APPROXIMATELY FOUR
                 MONTHS FROM ANNOUNCEMENT OF OFFER:

                             Day of May 22    Presentation to TIN
                                              Board of Directors Offer made

                                              announcement made

                           Week of July 21    File proxy statement with SEC

                         Week of August 18    Mail proxy materials to
                                              shareholders

OVERVIEW OF STRATEGIC RATIONALE

         o       TIN HAS DELIVERED SUBSTANTIAL SHARE APPRECIATION TO INVESTORS
                 WHILE CAN HAS TRAILED TIN OVER THE LAST FIVE YEARS. DESPITE A
                 RECENT PULLBACK IN THE STOCK RELATED TO THE ANNOUNCEMENT OF
                 CAN EAST, TIN HAS STILL DELIVERED SUPERIOR RETURNS TO
                 INVESTORS.

REASONS FOR BUY-IN

         o       CURRENT CONFIGURATION (85% OWNERSHIP) DOES NOT APPEAR TO
                 ENHANCE:

                 -        Valuation

                 -        Credit standing

                 -        Capital raising capabilities

         o       BUY-IN STREAMLINES TIN CREDIT PROFILE:

                 -        Ability to consolidate debt at holding company level
              
                 -        Capture of 100% of cash flow from CAN that is
                          substantially greater than amount TIN receives in
                          dividends

                 -        Cash flows of TIN could be available to CAN

         o       ELIMINATES MINORITY INTEREST ACCOUNTING FROM CONSOLIDATED
                 FINANCIAL STATEMENTS

TRANSACTION IMPLICATIONS - INVESTOR PERSPECTIVE

              o       ELIMINATION OF PURE "STEEL" PLAY OPPORTUNITY

                      -   Current illiquidity makes CAN a difficult investment
                          for institutions

                      -   Many current investors own the stock based upon
                          financial or technical play and not as a "Steel"
                          company

                      -   Potential loss of steel analyst coverage

              o       BUY-IN INCREASES STEEL PROFILE OF TIN

              o       CAPITAL EXPENDED TO FUND BUY-IN

================================================================================
TRANSACTION IMPLICATIONS - FINANCIAL

         o       TIN MAY INCUR ADDITIONAL GOODWILL FROM THE TRANSACTION

                 -        Purchase price may exceed minority share book value
                          in CAN

         o       DEPENDING ON SOURCE AND COST OF FUNDS USED, TRANSACTIONS CAN
                 BE MODESTLY ACCRETIVE TO TIN EARNINGS PER SHARE

         o       GIVEN PRIOR CONSIDERATIONS, TRANSACTIONS WILL LIKELY HAVE
