              ROBERTSON-CECO CORPORATION EXPRESSES DISMAY AT BUTLER
         MANUFACTURING COMPANY'S REFUSAL TO CONSIDER SUPERIOR PROPOSAL

          RCC BELIEVES THAT THE BUTLER BOARD WILL VIOLATE ITS FIDUCIARY
            DUTIES IF IT FAILS TO MEET WITH RCC TO DISCUSS RCC'S $23
               PER SHARE MERGER OFFER AND FINANCING ARRANGEMENTS

         CHICAGO, April 20, 2004. Robertson-Ceco Corporation, a Delaware
corporation ("RCC"), today expressed its dismay at the refusal of Butler
Manufacturing Company's board to explore the proposed combination of RCC's
operating divisions with Butler.

         On Friday, RCC provided Butler with proposals from Longleaf Partners
Small-Cap Fund ("Longleaf") and LaSalle Bank N.A. ("LaSalle") to provide equity
and debt financing for the transaction. In a statement issued on Monday, Butler
described the proposal, which offers shareholders the option of receiving $23 in
cash or shares in the combined company valued at $26 per share, as vague and
uncertain. RCC is dismayed by Butler's response.



         RCC'S PROPOSAL IS NOT VAGUE: Under RCC's proposal, all Butler
         shareholders will have the right to elect to continue their ownership
         of shares in the combined company of Butler and Robertson-Ceco. Or
         alternatively to choose to have their Butler shares converted into the
         right to receive $23 per share in cash. "Given the improving industry
         fundamentals for pre-engineered metal buildings and the clear
         opportunity to enhance the financial performance of Butler, we are
         dismayed that the Butler Board would deny shareholders the opportunity
         to go forward with more advantageous clear options for the Butler
         shareholders," noted Michael E. Heisley, Sr., Chief Executive Officer
         of Robertson-Ceco.

         RCC'S PROPOSAL IS NOT UNCERTAIN: RCC has received financing proposals
         described below and previously described to the Butler Board.
         Considering the projections of Butler for this year (projected EBITDA
         of approximately $39 million for 2004), RCC believes that the debt of
         the combined enterprise would be less than 2x EBITDA, which RCC
         believes eliminates the uncertainty of available financing. Indeed, RCC
         has arranged for financing, and all the Butler Board must do to
         determine its certainty is to allow the lenders to make simplistic and
         technical confirmations. It seems that the Butler Board has not taken
         into consideration the improved operations in assessing the certainty
         of the financing.

         Longleaf has submitted a proposal to purchase up to $100 million (but
not less than $60 million) of newly issued Butler shares at a purchase price of
$23 per share. The funds received from Longleaf would be used to repurchase
Butler shares, also at a purchase price of $23 per share, from shareholders who
elect to take cash rather than continue as a shareholder in the combined
enterprise. The Heico Companies and its affiliates would provide any additional
funding necessary to purchase outstanding Butler shares if shares having a value
over $100 million are exchanged for cash. If less than $60 million is required
to repurchase shares, Longleaf's investment would be reduced to $60 million and
any excess by which $60 million exceeds the amount necessary to fund the
repurchase of shares will be applied to reduce Butler debt. It should be
emphasized that the Longleaf and Heico investments will be into the common
equity of the combined enterprise and will therefore rank equally with
outstanding shares issued to current Butler shareholders.

         The Blue Scope proposal forces all Butler shareholders to accept $22.50
per share in cash, an amount determined at a low point in the business cycle.
Acceptance of the Blue Scope proposal will eliminate the benefits to
shareholders from the increased values which RCC expects will result from the
rapidly improving business cycle for the pre-engineered metal buildings
business. RCC expects the improving business cycle, as well as synergies and
significantly improved margins which should be realized in a combined
enterprise, will inure to the benefit of shareholders who would continue their
ownership of shares. In addition, since RCC believes the Butler debt can be
readily refinanced, acceptance of the Blue Scope proposal cannot reasonably be
based on the inability to refinance Butler debt.

         "We believe that RCC and our financial partners bring more than
adequate resources to successfully fund this transaction. The availability of
financing could be confirmed quite easily if Butler would agree to cooperate
with Longleaf and LaSalle and share current financial information with them. We
are disappointed by the board's lack of commitment to the process, given that



our proposal would result in a more favorable outcome for Butler's
shareholders," said Heisley.

         Contrary to Butler's assertion, Heisley noted that RCC OPERATED ON A
PROFITABLE BASIS FOR THE PAST 8 YEARS. RCC reiterated that it is prepared to
finalize a merger agreement and either refinance or purchase all of the senior
notes and further extend the Noteholder Amendment Agreement prior to April 30,
2004, when it expires.

         RCC believes that the Butler Board should determine in fulfillment of
its fiduciary duties to withdraw its recommendation that the Butler shareholders
vote for approval of the Blue Scope proposal.
