As Advisor to the Board of Directors
of Butler Manufacturing Company

Dear John:

         This letter renews the proposal set forth in the letter of
Robertson-Ceco Corporation ("RCC") to the Board of Directors of Butler
Manufacturing Company, dated April 13, 2004. In addition, this letter identifies
the financing sources for the proposed transaction.

         Enclosed is a copy of a proposal from the Longleaf Partners Small-Cap
Fund to provide up to $100 million of capital to facilitate the purchase of
Butler shares from shareholders who make the cash election. Also enclosed is a
proposal from LaSalle Bank National Association to provide up to $225 million of
financing in connection with the proposed combination.

         RCC is prepared to deliver to Butler audited financial statements for
its five past fiscal years, upon receipt of a customary confidentiality
agreement.

         RCC believes that its proposal is a "Superior Proposal" under Butler's
Agreement and Plan of Merger with BlueScope Steel Limited and requests Butler to
cooperate with the identified capital sources and RCC to confirm the available
funding, and ultimately to withdraw its recommendation that the Butler
shareholders vote for approval of the BlueScope proposal.

                                             Very truly yours,

                                             Robertson-Ceco Corporation

Attn: Mr. Michael Heisley

Dear Mr. Heisley:

         We are pleased to present, for your consideration, our proposal for an
investment by Longleaf Partners Small-Cap Fund of between sixty million dollars
($60,000,000) and one hundred million dollars ($100,000,000) in Butler
Manufacturing Company ("Butler") concurrently with a proposed transaction for
the combination of Butler with the three operating divisions of Robertson Ceco
Corporation as described in the proposal letter attached hereto as Exhibit A
(the "Transaction). As set forth in more detail in the attached term sheet, the
investment would be made concurrently with the closing of the Transaction.

         The term sheet attached hereto as Exhibit B is for discussion purposes
only and, except as set forth therein, is not binding. The completion of the
transactions contemplated by the term sheet would be subject, among other
things, to our satisfactory completion of financial and legal due diligence, as
well as the execution of definitive agreements acceptable to us with respect to
the proposed investment and the Transaction.

         We are excited about the proposed investment and very much look forward
to working with you in implementing a transaction that would be in the best
interests of all parties involved.

                                    Very truly yours,

The Board of Directors
Butler Manufacturing Company
1540 Genessee Street
Kansas City, Missouri 64102

Gentlemen:

         This letter sets forth a proposal for the combination of the businesses
of Butler Manufacturing Company, a Delaware corporation ("Butler"), and the
three operating divisions of Robertson Ceco Corporation, a Delaware corporation
("RCC"), and an opportunity for liquidity for Butler shareholders who desire it.
The three operating divisions of RCC, each of which is engaged in North America
in the design, fabrication and sale of pre-engineered buildings, are Star
Building Systems ("Star"), Ceco Building Systems ("Ceco") and Robertson Building
Systems Canada ("RBS").

         Under our proposal, Butler shareholders will have the right to elect to
receive in cash $23 per share or alternatively to continue their ownership of
shares in the combined company. We believe the shares in the publicly traded,
combined company will have a long term value significantly above $23 per share.

         We have arranged to refinance outstanding Butler debt, including
letters of credit. We are prepared to purchase all three series of the 8.02%,
the 6.57% and the 7.87% Senior Notes issued by Butler and further extend the
Noteholder Amendment and Acknowledgement Agreements. In connection therewith, we
are prepared to offer the existing noteholders a value of par plus accrued
interest plus the "make-whole" payment at the completion of the transaction.

         We believe that our proposal as set forth below is superior to the
BlueScope buyout proposal. Accordingly, we respectfully suggest that the Butler
Board of Directors should determine in fulfillment of its fiduciary duties to
withdraw its recommendation that the Butler shareholders vote for approval of
the BlueScope proposal.

         The combined net sales and EBITDA of Star, Ceco and RBS for the year
ended December 31, 2003, and the average annual combined net sales and EBITDA of
Star, Ceco and RBS for the five years ended December 31, 2003 are as follows:

Net sales           $287.6 million                 $291.9 million

EBITDA              $ 16.6 million                 $ 27.3 million


A combined balance sheet for the three divisions at December 31, 2003, excluding
all assets and liabilities to be retained by RCC, is attached hereto as Exhibit
A.

         We propose to combine the operating divisions of RCC and Butler in a
transaction that values the shares of Butler common stock at $26,00 per share.
The RCC operating divisions would be valued at 6.7x the average EBITDA of the
divisions for the five years ended December 31, 2003. The multiple of 6.7x
EBITDA when applied to Butler's average annual EBITDA for the same period
results in a value of $22,50 per Butler common share, as proposed to be paid by
BlueScope. Based on these values, we believe the combination of Butler and the
RCC operating divisions is immediately accretive to Butler's shareholders. See
Exhibit B, As part of the transaction proposed by us, Butler shareholders who do
not wish to continue their ownership of shares in the combined enterprise would
be given the opportunity to receive $23.00 per Butler common share in cash.

         We propose that the transaction will be effected as follows:

                  1.       RCC will transfer all of the operating assets and
                           liabilities of each of Star, Ceco and RBS to newly
                           formed corporations for each respective division. In
                           addition, each division will assume any currently
                           outstanding indebtedness relating to its business and
                           assets. RCC will retain certain intercompany
                           obligations owed to it by affiliates and certain
                           liabilities (including contingent claims) relating to
                           discontinued operations.

                  2.       RCC will transfer the stock of the newly formed
                           corporations to a newly formed corporation ("Newco"),
                           and Newco will form an acquisition subsidiary ("Newco
                           Acquisition").

                  3.       Butler will commit to issue shares of its common
                           stock at a price of $23.00 per share immediately
                           prior to the merger described below, in an amount
                           sufficient to fund the cash portion of the merger
                           described in item 4 below, but not less than $60
                           million of newly issued shares. RCC has identified
                           investors who are prepared to commit to purchase the
                           shares to be issued.

                  4.       Newco Acquisition will merge with and into Butler.
                           Butler shareholders will elect to either receive cash
                           at $23 per share or receive one registered Newco
                           share for each Butler share. Newco will own 100% of
                           Butler, will change its name to Butler ("New
                           Butler"), and will become the public

                           reporting company. It is anticipated that following
                           the merger, a minimum of approximately 43.1% of the
                           New Butler shares will be held by RCC and 16.6% by
                           the new investors.

                  5.       Following the merger, RCC nominees will constitute a
                           majority of the board of directors of New Butler. At
                           least three (3) current Butler directors will be
                           asked to continue as members of the board of New
                           Butler.

                  6.       The Butler management contracts will be honored.

                  7.       Outstanding indebtedness of Butler will be
                           refinanced.

                  8.       RCC will continue in existence with substantial net
                           worth and will discharge its liabilities as they come
                           due.

         As a result of (a) the refinancing of Butler debt, (b) the synergies
derived from the combined operations, (c) value associated with the successful
conclusion of the Louisiana Pacific litigation and (d) input from RCC designated
board members, we believe that the market value of the New Butler shares will
significantly exceed the current BlueScope valuation of $22.50 per share.
Recognizing that the business cycle for the pre-engineered metal buildings
businesses in which Butler and RCC participate was at a five-year low in 2003,
we expect that Butler shareholders would also benefit from being able to
continue their share ownership when the business cycle improves. For these
reasons, we believe our proposal is superior for Butler shareholders than the
current BlueScope buyout proposal.

         RCC is ready to immediately negotiate and sign a definitive agreement
for the transaction, without contingencies. We believe that HSR clearance should
be obtained expeditiously. We suggest that any review by Butler of the Star,
Ceco and RBS businesses could be commenced immediately and concluded during the
next week or so while definitive agreements are prepared. Because we have also
conducted significant due diligence during our participation in your sale
process in late 2003, we have substantially completed our review of Butler. We
believe the transaction structure proposed herein allows us to put a value on
Butler above our valuation arrived at during the 2003 sales process.

         Provided that Butler's Board of Directors withdraws not later than
April 23, 2004 its recommendation that its shareholders approve the BlueScope
buyout proposal, our proposal will remain open until the close of business on
April 30, 2004. Please contact the undersigned at (312) 419-8220 to indicate
your acceptance of our proposal and with any questions you may have.

                                      Very truly yours,

                                                          April 13, 2004

CONFIDENTIAL
The Board of Directors
Butler Manufacturing Company
1540 Genessee Street
Kansas City, Missouri 64102

Gentlemen:

         This letter sets forth a proposal for the combination of the businesses
of Butler Manufacturing Company, a Delaware corporation ("Butler"), and the
three operating divisions of Robertson Ceco Corporation, a Delaware corporation
("RCC"), and an opportunity for liquidity for Butler shareholders who desire it.
The three operating divisions of RCC, each of which is engaged in North America
in the design, fabrication and sale of pre-engineered buildings, are Star
Building Systems ("Star"), Ceco Building Systems ("Ceco") and Robertson Building
Systems Canada ("RBS").

         Under our proposal, Butler shareholders will have the right to elect to
receive in cash $23 per share or alternatively to continue their ownership of
shares in the combined company. We believe the shares in the publicly traded,
combined company will have a long term value significantly above $23 per share:

         We have arranged to refinance outstanding Butler debt, including
letters of credit. We are prepared to purchase all three series of the 8.02%,
the 6.57% and the 7.87% Senior Notes issued by Butler and further extend the
Noteholder Amendment and Acknowledgement Agreements. In connection therewith, we
are prepared to offer the existing noteholders a value of par plus accrued
interest plus the "make-whole" payment at the completion of the transaction.

         We believe that our proposal as set forth below is superior to the
BlueScope buyout proposal. Accordingly, we respectfully suggest that the Butler
Board of Directors should determine in fulfillment of its fiduciary duties to
withdraw its recommendation that the Butler shareholders vote for approval of
the BlueScope proposal.

         The combined net sales and EBITDA of Star, Ceco and RBS for the year
ended December 31, 2003, and the average annual combined net sales and EBITDA of
Star, Ceco and RBS for the five years ended December 31, 2003 are as follows:

                  ----------------------------         -----------------------------
                                                 
Net sales                 $287.6 million                    $291.9 million

EBITDA                    $ 16.6 million                    $ 27.3 million


A combined balance sheet for the three divisions at December 31, 2003, excluding
all assets and liabilities to be retained by RCC, is attached hereto as Exhibit
A.

         We propose to combine the operating divisions of RCC and Butler in a
transaction that values the shares of Butler common stock at $26.00 per share.
The RCC operating divisions would be valued at 6.7x the average EBITDA of the
divisions for the five years ended December 31, 2003. The multiple of 6.7x
EBITDA when applied to Butler's average annual EBITDA for the same period
results in a value of $22.50 per Butler common share, as proposed to be paid by
BlueScope. Based on these values, we believe the combination of Butler and the
RCC operating divisions is immediately accretive to Butler's shareholders. See
Exhibit B. As part of the transaction proposed by us, Butler shareholders who do
not wish to continue their ownership of shares in the combined enterprise would
be given the opportunity to receive $23.00 per Butler common share in cash.

         We propose that the transaction will be effected as follows:

               1.   RCC will transfer all of the operating assets and
                    liabilities of each of Star, Ceco and RBS to newly formed
                    corporations for each respective division. In addition, each
                    division will assume any currently outstanding indebtedness
                    relating to its business and assets. RCC will retain certain
                    intercompany obligations owed to it by affiliates and
                    certain liabilities (including contingent claims) relating
                    to discontinued operations.

               2.   RCC will transfer the stock of the newly formed corporations
                    to a newly formed corporation ("Newco"), and Newco will form
                    an acquisition subsidiary ("Newco Acquisition").

               3.   Butler will commit to issue shares of its common stock at a
                    price of $23.00 per share immediately prior to the merger
                    described below, in an amount sufficient to fund the cash
                    portion of the merger described in item 4 below, but not
                    less than $60 million of newly issued shares. RCC has
                    identified investors who are prepared to commit to purchase
                    the shares to be issued.

               4.   Newco Acquisition will merge with and into Butler. Butler
                    shareholders will elect to either receive cash at $23 per
                    share or receive one registered Newco share for each Butler
                    share. Newco will own 100% of Butler, will change its name
                    to Butler ("New Butler"), and will become the public

                    reporting company. It is anticipated that following the
                    merger, a minimum of approximately 43.1% of the New Butler
                    shares will be held by RCC and 16.6% by the new investors.

               5.   Following the merger, RCC nominees will constitute a
                    majority of the board of directors of New Butler. At least
                    three (3) current Butler directors will be asked to continue
                    as members of the board of New Butler.

               6.   The Butler management contracts will be honored.

               7.   Outstanding indebtedness of Butler will be refinanced.

               8.   RCC will continue in existence with substantial net worth
                    and will discharge its liabilities as they come due.

         As a result of (a) the refinancing of Butler debt, (b) the synergies
derived from the combined operations, (c) value associated with the successful
conclusion of the Louisiana Pacific litigation and (d) input from RCC designated
board members, we believe that the market value of the New Butler shares will
significantly exceed the current BlueScope valuation of $22.50 per share.
Recognizing that the business cycle for the pre-engineered metal buildings
businesses in which Butler and RCC participate was at a five-year low in 2003,
we expect that Butler shareholders would also benefit from being able to
continue their share ownership when the business cycle improves. For these
reasons, we believe our proposal is superior for Butler shareholders than the
current BlueScope buyout proposal.

         RCC is ready to immediately negotiate and sign a definitive agreement
for the transaction, without contingencies. We believe that HSR clearance should
be obtained expeditiously. We suggest that any review by Butler of the Star,
Ceco and RBS businesses could be commenced immediately and concluded during the
next week or so while definitive agreements are prepared. Because we have also
conducted significant due diligence during our participation in your sale
process in late 2003, we have substantially completed our review of Butler. We
believe the transaction structure proposed herein allows us to put a value on
Butler above our valuation arrived at during the 2003 sales process.

         Provided that Butler's Board of Directors withdraws not later than
April 23, 2004 its recommendation that its shareholders approve the BlueScope
buyout proposal, our proposal will remain open until the close of business on
April 30, 2004. Please contact the undersigned at (312) 419-8220 to indicate
your acceptance of our proposal and with any questions you may have.

                                                          Very truly yours,

                                    action being taken or threatened by any
                                    competent authority which would restrain,
                                    prevent or otherwise impose adverse
                                    conditions on the Acquisition or the
                                    financing thereof contemplated by the

                                    third party approvals the failure to obtain
                                    which could not individually or in the
                                    aggregate, reasonably be expected to have a
                                    material adverse effect on the condition
                                    (financial or otherwise), business, assets,
                                    liabilities, properties, results of
                                    operations or prospects of the Loan Parties
                                    taken as a whole.

                                    Documents") shall have satisfactory terms
                                    and conditions, and no provision of such

                                    in any material respect. The Loan Parties
                                    shall have no debt other than the

                                    in all respects.

                                    that, since December 31, 2003, there has
                                    been no material adverse change in the

                                    condition (financial or otherwise), results

                           Upon acceptance of this Term Sheet, the Company
                           agrees to pay on demand all reasonable out-of-pocket
                           costs and expenses of the Administrative Agent

                           with the preparation, execution and delivery
                           (including the costs of Intralinks (or other similar

Taxes and Yield            The Company will indemnify the Lenders for
Protection:                withholding taxes. The definitive loan documents will
                           also contain customary tax gross-up, yield protection

Voting:                    Required Lenders shall be equal to 66-2/3% or more of
                           commitments under the Facilities, except that (a) the
                           consent of each Lender directly affected thereby
                           shall be required with respect to (i) reductions in
                           the amount of, or extensions of the scheduled date of
                           amortization or final maturity of, any loan, (ii)

                           of 100% of the Lenders shall be required with respect
                           to (i) modifications of the voting percentages and

                           of the guarantees or all or substantially all of the

Syndication:               Upon acceptance of this term sheet, LaSalle may
                           initiate discussions with potential lenders relating
                           to the syndication of the Facilities. LaSalle will
                           syndicate the transaction with the assistance of the
                           Company. Such assistance shall include, but not be
                           limited to: (i) prompt assistance in the preparation
                           of an information memorandum and verification of the
                           accuracy and completeness of the information
                           contained therein; (ii) preparation of other
                           materials and projections by the Company and its
                           advisors taking into account the proposed Facilities;
                           (iii) providing LaSalle with all information
                           reasonably deemed necessary by LaSalle to
                           successfully complete the syndication; (iv)
                           confirmation as to the accuracy and completeness of
                           such offering materials, projections and information
                           and (v) participation of the Company's senior
                           management in meetings and

                                       7



                           conference calls with potential lenders and rating
                           agencies, if applicable, at such times and places as
                           LaSalle may reasonably request.

                           Neither LaSalle nor any of its affiliates (i) can
                           provide any assurances that a syndicate of Lenders
                           can be arranged, and (ii) shall not have any
                           liability should a syndicate not materialize. LaSalle
                           intends to fully underwrite the loans on the closing
                           date subject to receiving commitments from other
                           Lenders acceptable to the Company and LaSalle. These
                           Lenders shall have committed, on terms acceptable to
                           the Company and LaSalle, in an amount no less than
                           $150.0 million. Subsequent to the closing date, if
                           less than all required commitments are obtained, the
                           Agent may make adjustments to the pricing, structure,
                           terms or amount of the Facilities required to effect
                           a successful syndication. The agreement in the
                           foregoing sentence shall survive closing of the loans
                           and continue in effect until a successful syndication
                           has been completed. For purposes of the foregoing,
                           "successful syndication" means that LaSalle has
                           achieved its target hold level of $50.0 million.

                           LaSalle may provide to industry trade organizations
                           information with respect to the Facilities that is
                           necessary and customary for inclusion in league table
                           measurements.

Assignments and            Each Lender may at any time sell assignments in the
Participations:            Facilities to eligible financial institutions or
                           commercial banks in minimum amounts of $5.0 million
                           (or all of such Lender's remaining loans and
                           commitments) subject to the consent of the
                           Administrative Agent, the Issuing Lender (for
                           assignments of the Revolving Credit Facility only)
                           and (so long as no event of default has occurred and
                           is continuing) the Company (which shall not be
                           unreasonably withheld or delayed). Each Lender may
                           sell participations in all or any part of the
                           Facilities, provided such participants shall only
                           have voting rights with respect to certain customary
                           or affected Lender consent items.

Governing Law and          The loan documents will be governed by Illinois law.
Forum:                     The Loan Parties will submit to the jurisdiction and
                           venue of the federal and state courts located in Cook
                           County in the State of Illinois and will waive any
                           right to trial by jury.

Counsel to the             To be determined.

                           reserve requirements.

                           Base Rate: The higher of (a) the rate publicly
                           announced from time to time by the Administrative

                           daily unutilized portion of the Revolving Credit
                           Facility. Such fee will be payable monthly in arrears
                           on the last day of each calendar month. The undrawn
                           amount of letters of credit will count as utilization
                           of the Revolving Credit Facility for purposes of
                           calculating this fee.

                           by reference to the Pricing Grid will be payable on

                           on the last day of each calendar month. In addition,
                           the Company will pay the Issuing Lender for its own

                           in the amount separately agreed to between the
                           Company and the Issuing Lender and (b) such other
                           standard issuance, negotiation, processing and/or
                           administration fees as may be charged by the Issuing
                           Lender.

Default Rate:              Upon the occurrence and during the continuance of a
                           default, unless the Required Lenders otherwise
                           consent, the obligations under the Facilities will
                           bear interest at a rate equal to an additional two
                           percent (2%) per annum over the rate otherwise
                           applicable, with such interest payable on demand.
                           Imposition of the default rate will be automatic for
                           payment and insolvency defaults.

Upfront Fees:              2.00% on the Facilities payable at close. It is
                           understood and agreed that no other Lender shall
                           receive compensation from the Company in order to
                           obtain its commitment therein.

EXHIBIT B

BUTLER MANUFACTURING COMPANY DIRECTORS CONCLUDE:
ROBERTSON-CECO PROPOSAL MORE UNCERTAIN, CONTINGENT
THAN HAD BEEN ORIGINALLY SUSPECTED

         KANSAS CITY, MO, April 19, 2004 -- After review and consultation with
its financial advisors and outside legal counsel, the Board of Directors of
Butler Manufacturing Company (BBR:NYSE) has determined that the additional
information provided by Robertson-Ceco Corporation ("RCC") on April 16, 2004
only served to highlight the vagueness and uncertainty of RCC's proposal to
acquire Butler.

         "The Board believes the RCC proposal is riddled with contingencies,"
said John Holland, Chairman and Chief Executive Officer of Butler. "Because the
RCC proposal is too vague and uncertain for the Board to conclude that it
represents a Superior Proposal, Butler is precluded under the merger agreement
with BlueScope Steel Limited ("BlueScope") from entering into or participating
in discussions with RCC at this time. The Board continues to recommend that
Butler stockholders vote for approval and adoption of the BlueScope merger
agreement."

         On April 16, Butler received additional information from RCC regarding
its unsolicited proposal to acquire Butler. RCC also issued a related press
release on April 16 purporting to describe this additional information. While
RCC chose to publish and file with the SEC its original April 13, 2004 letter to
Butler's Board of Directors, RCC chose not to publish in full the April 16
information. In the interest of full disclosure, Butler is today filing with the
SEC a complete copy of the April 16 information delivered by RCC to Butler.

         As previously announced and described in the proxy statement mailed to
Butler stockholders on March 26, 2004, Butler has entered into an Agreement and
Plan of Merger with BlueScope whereby Butler stockholders would be entitled to
receive $22.50 per share in cash. A special meeting of Butler stockholders is
scheduled on April 27, 2004 to vote on the proposed merger with BlueScope. As
previously announced on April 16, Butler expects to meet the financial
milestones established in the BlueScope merger agreement for the quarter ended
March 31, 2004 that are a condition to BlueScope's obligation to consummate the
merger.

         Under the terms of the merger agreement with BlueScope, a Superior
Proposal is defined as an acquisition transaction that is reasonably likely to
be consummated on the terms proposed, taking into account all legal, financial,
regulatory and other aspects, and would result in a more favorable outcome than
the BlueScope merger from a financial point of view to Butler stockholders if
consummated, taking into account the proposed timing.

         The April 16 information purported to provide evidence of equity
financing that was available to RCC from Longleaf Partners Small-Cap Fund
("Longleaf") and debt financing from LaSalle Bank N.A. ("LaSalle"). In reviewing
these materials, the Board had the following observations and concerns:




         o  The Longleaf and LaSalle proposals are non-binding term sheets--in
            the case of Longleaf "for discussion purposes only", and in the case
            of LaSalle "does not constitute a commitment"--and do not represent
            any promise to provide funding;

         o  The Longleaf and LaSalle proposals clearly indicate any funding
            would be subject to detailed documentation and legal, financial and
            business due diligence on both Butler and the RCC companies,
            including environmental and other field audits and the like, as well
            as special comfort on other matters such as available insurance
            coverage and trends regarding RCC's asbestos claims and the solvency
            of RCC before and after the transaction, all of which would
            reasonably be expected to be a lengthy process, even if successfully
            concluded;

         o  Nothing in the Longleaf and LaSalle proposals alters the fact that
            the RCC proposal is complex, multi-party, highly contingent and
            conditional, and lacks any formal agreements, timetable or
            assurances that it would ever be consummated;

         o  The $26.00 per share value referenced by RCC is not a cash payment
            to Butler stockholders but merely a hypothetical value used as a
            means for establishing an exchange ratio for Butler's stock relative
            to RCC's stock in a merger transaction. Despite RCC's implications
            to the contrary in the April 16 press release, RCC has given no
            assurance that the actual trading value for Butler's stock in the
            market would be $26.00 per share following the completion of a
            transaction;

         o  The proposed combined balance sheet provided for the three RCC
            operating entities reflects $42 million of cumulative losses;

         o  The Board continues to be mindful of the existing Noteholder
            Amendment Agreement, dated December 30, 2003, that requires Butler
            to conclude a transaction that provides for payment in full of all
            Butler's obligations to its senior noteholders by April 30, 2004,
            and believes that the merger with BlueScope will be closed, subject
            to stockholder approval, immediately following the special meeting
            of Butler stockholders on April 27.

         The Board weighed the relative certainty of the BlueScope merger
against the apparent risk and uncertainty associated with consummating the
transactions outlined in the RCC proposal. In light of Butler's current
financial condition, the Board also considered the risks of continuing to
operate Butler's business for the extended period of time necessary to seek to
conclude the transactions proposed by RCC. These factors also contributed to the
Board's evaluation of the RCC proposal.

         "We are convinced that the merger with BlueScope represents the best
available transaction for Butler shareholders," said Holland.

         Butler Manufacturing Company is the world's leading producer of
pre-engineered building systems, a leading supplier of architectural aluminum
systems and components, and provides construction and real estate services for
the nonresidential construction market.
