           ROBERTSON-CECO CORPORATION AMENDS OFFER TO $24.50 PER SHARE
                                     IN CASH
    RCC NEGOTIATES ADDITIONAL FINANCING COMMITMENT TO FINANCE THE TRANSACTION

         CHICAGO, April 22, 2004. Robertson-Ceco Corporation, a Delaware
corporation ("RCC"), today improved its offer to provide liquidity to
shareholders of Butler Manufacturing Company in a combination with the operating
businesses of RCC. Under the improved proposal, Butler shareholders will have
the right to continue their ownership of shares in the combined company or
alternatively to choose to have their Butler shares converted into the right to
receive $24.50 per share in cash. All Butler shareholders may elect to receive
$24.50 per share in cash for all of their shares.

         In addition to the financing provided by Longleaf Partners Small-Cap
Fund ("Longleaf") and The Heico Companies ("Heico"), RCC has negotiated a bridge



facility to fund/refinance the outstanding debt of Butler. The financing is not
dependent upon the assets or credit rating of Butler.

         In addition to the above bridge financing, Longleaf has proposed to
purchase up to $100 million shares of the combined entity at a purchase price of
$23 per share. The funds received from Longleaf would be used to pay the cash
conversion price for Butler shares, at a purchase price of $24.50 per share. If
additional funding is needed to pay for Butler shares exchanged for cash, The
Heico Companies (owner of 97% of RCC) would purchase additional newly issued
Butler shares at $23 per share to cover the additional funding requirements. 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 cash conversion of Butler shares will be applied to
reduce Butler debt. It should be emphasized that the Longleaf and Heico
investments will be in the common equity of the combined enterprise and will
therefore rank equally with outstanding shares issued to current Butler
shareholders who elect to retain stock ownership.

         RCC's amended proposal is clearly SUPERIOR to the proposal by Blue
Scope. 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 opportunity for
shareholders to participate in the increased values which RCC expects will
result from an improved business cycle for pre-engineered metal buildings, as
well as the synergies and improved margins which could be realized in a combined
enterprise.

         "We believe that RCC and our financial partners bring all the requisite
resources to successfully fund this transaction." said Michael E. Heisley, Sr.,
Chief Executive Officer of Robertson-Ceco.

this filing that has been taken from such documents is inaccurate or incomplete,
RCC does not take any responsibility for the accuracy or completeness of such
information.

         This announcement is neither an offer to purchase nor a solicitation of
an offer to sell shares of Butler or the combined company. Investors and
security holders are urged to read the disclosure documents regarding the
proposed RCC/Butler transaction, when they become available, because they will

from its shareholders or from the shareholders of Butler. However, in connection
with its proposal to merge with Butler, certain directors and officers of RCC
may participate in meetings or discussions with RCC shareholders some of whom

shareholders. RCC does not believe that any of these persons is a "participant"
as defined in Schedule 14A promulgated under the Securities Exchange Act of
1934, as amended, in the solicitation of proxies or consents, or that Schedule
14A requires the disclosure of certain information concerning any of them.

         If in the future RCC does engage in a solicitation of proxies or
consents from its shareholders or the shareholders of Butler in connection with
its proposal to merge with Butler it will amend the information provided above
to disclose the information concerning participants in that solicitation
required by Rule 14a-12 under the Securities Exchange Act of 1934.
