                  BUTLER MANUFACTURING COMPANY AND SUBSIDIARIES
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1 - BASIS OF PRESENTATION
The accompanying unaudited consolidated condensed financial statements have been
prepared in accordance with the accounting policies described in the
consolidated financial statements and related notes included in Butler
Manufacturing Company's 2000 Form 10-K. It is suggested that those consolidated
statements be read in conjunction with this report. The year-end financial
statements presented were derived from the company's audited financial
statements. In the opinion of management, the accompanying consolidated
financial statements reflect all adjustments necessary for a fair presentation
of the financial position of Butler Manufacturing Company and the results of its
operations.

NOTE 2 - NEW ACCOUNTING PRONOUNCEMENT
In July 2001, the Financial Accounting Standards Board (SFAS), issued Statement
No. 141, "Business Combinations, and SFAS No. 142, "Goodwill and Other
Intangible Assets." SFAS No. 141 requires all future acquisitions after June
30, 2001, to be accounted for under the purchase method of accounting. In
addition, if further clarifies the criteria for recognition of intangible
assets separately from goodwill. SFAS No. 142 provides guidance on the
accounting and reporting for goodwill and intangible assets. Goodwill will no
longer be amortized over its estimated useful life, but will be assessed
annually for impairment using a fair value based test.

The Company will adopt these new standards on January 1, 2002. At the end of
the second quarter the company had goodwill of $6.0 million. The Company is in
the process of evaluating the application of these pronouncements.

NOTE 3 - BUSINESS SEGMENTS
The Company groups its operations into five business segments: North American
Building Systems, International Building Systems, Architectural Products,
Construction Services, and Real Estate.

The North American Building Systems segment includes the North American metal
buildings and the wood buildings businesses. These business units supply steel
and wood frame pre-engineered building systems for a wide variety of commercial,
community, industrial, and agricultural applications.

The International Buildings Systems segment includes the Company's Asian and
European metal buildings businesses. These businesses supply pre-engineered
metal buildings for commercial, community, industrial, and agricultural
applications primarily for the Chinese and European markets.

The Architectural Products segment includes the operations of the Vistawall
Group. The group's businesses design, manufacture, and market architectural
aluminum systems for nonresidential construction, including curtain wall,
storefront systems, windows, doors, skylights, and roof accessories.

The Construction Services segment provides comprehensive design and construction
planning, execution, and management services for major purchasers of
construction. Projects are usually executed in conjunction with the dealer
representatives of other Butler divisions.

The Real Estate segment provides real estate build-to-suit-to-lease development
services in cooperation with Butler dealers.

The accounting policies for the segments are the same as those described in the
summary of significant accounting policies as included in the company's 2000
form 10-K. Butler Manufacturing Company's reportable segments are strategic
business units that offer products and services for different markets. They are
managed separately because each business requires different technology and
expertise.

The Other classification represents unallocated corporate expenses and
unallocated assets, including corporate offices, deferred taxes, pension
accounts, interest expense, and intersegment eliminations.

Assets represent both tangible and intangible assets used by each business
segment. Other represents cash and cash equivalents, assets held for sale,
corporate equipment, and miscellaneous other assets which are not related to a
specific business segment. In prior periods, the North American Building
Systems and International Building Systems were reported as a single segment.
Because of reorganization and management changes, two segments were formed.

NOTE 4 - RESTRUCTURING AND ASSET IMPAIRMENT CHARGES
In December 1998, the company's board of directors approved a restructuring of
the South American and European metal buildings businesses. As a result, the
company recorded a $7.1 million pretax charge in connection with the
restructuring. In addition, the company recorded a $6.5 million pretax charge
for the impairment of certain assets. The actions leading to the restructuring
charge were the closing of manufacturing operations in Brazil and repositioning
of European operations. Estimates of realizable asset sales values were obtained
from outside appraisals and the company's experience in selling redundant
assets.

During the first quarter of 1999, the company recorded an additional $1.5
million restructuring charge for currency translation losses on its remaining
Brazilian net asset exposure.

At the end of the first quarter 2000, $.9 million of the restructuring accrual
remained. Final activities related to restructuring were completed in the second
quarter 2000, resulting in a $.4 million reversal of the remaining accrual.

NOTE 5 - CHANGE IN ACCOUNTING FOR PENSION COSTS
Effective January 2001, the company changed its method for the recognition of
deferred gains and losses considered in the calculation of the annual net
pension expense for its base retirement pension plan under SFAS 87, "Employers'
Accounting for Pensions. " The company has changed from the market value method
of asset valuation to the market-related value method. Under the previous
accounting method all gains and losses, subject to a ten-percent corridor, were
recognized and amortized in determining the net periodic pension costs. The new
method recognizes and amortizes 20 percent of the cumulative investment gains or
losses in determining net periodic pension costs. The new method is commonly
used by the manufacturing sector and is preferable because it more accurately
matches expense to accounting periods for which benefits are earned. The new
method also improves year-to-year comparability of net period costs for this
plan.

Adoption of this change reduced income from operations and net income for the
three months ending June 30 and March 31, 2001 by $.2 million and $.1 million,
respectively. The per share impact on each quarter was $.02. The effect on net
earnings if these changes were adopted in prior years is immaterial.

The company also changed effective April 1, 2001, the period used to amortize
prior service costs associated with retroactive amendments of benefits for its
hourly pension plans. Previously, the effect of these amendments was amortized
over the average future working lifetime of those expected to receive benefits.
The new period used for amortization of prior service costs attributed to the
amendments is the number of years in which the benefit is earned. The effect of
this change is to increase net periodic pension costs and decrease income from
continuing operations by $.2 million for the three months ending June 30, 2001.

NOTE 6 - INDEBTEDNESS
The company entered into a new $50 million bank credit facility and issued $50
million of senior unsecured notes pursuant to a note agreement at the end of
June, allowing domestic bank borrowings to be reduced to zero.

The new credit agreement was entered into with the Bank of America, N.A. as
administrative lender and certain other lenders. Interest on advances under the
new credit facility are based on either (a) the higher of the federal funds rate
plus .50% or the Administrative Lender's prime rate, which is payable quarterly,
or (b) LIBOR, which is payable at the end of periods ranging from one to six
months. The new credit agreement provides for a commitment fee on unused
advances ranging from .20% to .30%. Commitments under the new credit facility
expire on June 30, 2004, at which time any outstanding advances are payable. The
agreement contains certain operating covenants, including restrictions on liens,
investments, acquisitions, asset sales and mergers. The agreement also requires
the Company to maintain a capitalization ratio, as defined, of .5 to 1, a fixed
charge coverage ratio, as defined, of 1.7 to 1, and a leverage ratio, as defined
of 3.25 to 1 through June 30, 2002 and 3.0 to 1 thereafter.

The senior notes bear interest, payable semi-annually on June 30 and December
30, at the rate of 7.91% per annum. Principal of the Senior Notes is payable in
annual installments of $4.55 million on December 30th of each year, commencing
December 30, 2006, with the balance due on the December 30, 2016 maturity date.
The Note Agreement contains certain operating covenants, including restrictions
on liens, additional indebtedness and asset sales, and requires the Company to
maintain adjusted consolidated net worth, as defined, of $125 million plus the
cumulative sum of 50% of consolidated net income for each fiscal quarter after
March 31, 2001 and a fixed charge coverage ratio, as defined, of 1.5 to 1.0.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS

RESULTS OF OPERATIONS
Net sales for the second quarter were $214 million, down 12% for the same period
a year ago primarily due to lower sales in the North America Building Systems,
Construction Services, and Real Estate segments. The North American Building
Systems segment sales, which includes the pre-engineered steel and wood
buildings businesses, declined 13% in the second quarter compared to the prior
year. This segment continues to be effected by a weakening U.S. economy and
poorer weather through most of the second quarter, resulting in lower
non-residential building sales. Construction Services segment sales declined 25%
during the second quarter 2001 compared to the prior year as anticipated, due to
the decision to focus this business primarily on material-erect opportunities.
Real Estate segment sales decreased from a year ago, due to lower project sales.
Architectural Products segment sales increased 4% in the second quarter 2001
compared with the same period a year ago as demand for storefront and
curtain-wall products remained strong. The International Building Systems
segment, which includes the Chinese and European metal buildings businesses, was
reported separately for the first time in the second quarter 2001. These
businesses were previously reported with domestic pre-engineered steel and wood
buildings businesses. Their second quarter sales increased 8% compared with the
prior year primarily due to somewhat stronger pre-engineered metal buildings
sales in the Asian markets.

For the six months ended June 30, 2001 net sales were $409 million compared with
$463 million in 2000, a decrease of 12%. Declining sales in the North American
Building Systems and Construction Services segments make up most of the six
month decline in sales, offset somewhat by improved sales in the Architectural
Products, Real Estate and International Building Systems segment.

Pretax earnings for the quarter ended June 30, 2001 were $5.2 million compared
with $10.6 million, a year ago. For the six months ended June 30, 2001, pretax
earnings were $.7 million versus $14.3 million in 2000. The sluggish U.S.
economy, and slowing China and European markets, have resulted in competitive
pricing which has unfavorably effected pretax earnings in all business segments.

LIQUIDITY AND CAPITAL RESOURCES
Since December 2000, cash and equivalents increased $1.4 million. Capital
expenditures, the payment of dividends and short-term debt were the primary uses
of cash. Sources of cash were from operations, including a decrease in working
capital, and an increase in long-term debt relate to the new $50 million bank
credit facility. For the six months ended June 30, 2001, domestic short-term
borrowings averaged $40 million for 181 days compared to $11 million for 108
days in 2000.

The company entered into a new $50 million bank credit facility and signed a new
$50 million private placement agreement at the end of June allowing domestic
bank borrowings to be reduced to zero. The company's foreign operations maintain
separate lines of credit with local banks of approximately $7 million, with $2
million utilized at current exchange rates at June 30, 2001. Management believes
the company's operating cash flow, along with the bank credit lines, are
sufficient to meet future liquidity requirements.

Capital expenditures were $19 million for the first six months of 2001 compared
to $15 million for the same period in 2000. Total capital expenditures for 2001
are expected to be $54 million. It is estimated that approximately $26 million
will be used to construct the Company's new headquarters building. Other
expenditures include costs to complete the installation of process lines in the
new Vistawall extrusion plant in Tennessee and expansion of the Shanghai, China
office facility.

Cash paid for taxes and interest totaled $.4 million and $1.3 million in the
second quarter 2001, compared with $3.9 million and $1.1 million for the same
period a year ago. Cash paid for taxes and interest for the six month period
were $1.8 million and $3.0 million, compared with $4.8 million and $2.3 million
for the same period a year ago.

During the second quarter of 2001, treasury stock purchases were minimal
compared with the prior year, and dividends paid totaled $1 million. Total
backlog of $342 million increased 2% from comparable backlog of a year ago.
Higher margin product backlog was equal to a year ago and construction backlog
increased 10% for the same period.

MARKET PRICE RISK
The company's principal exposure to market risk is from changes in commodity
prices, interest rates, and currency exchange rates. To limit exposure and to
manage volatility related to these risks, the company enters into select
commodity and currency hedging transactions, as well as forward purchasing
arrangements. The company does not use financial instruments for trading
purposes.

Commodity Price Exposure: The company's primary commodities are steel, aluminum,
and wood. Steel is the company's largest purchased commodity. The company enters
into forward steel purchase arrangements in its metal buildings business for
periods of less than one year duration to protect against potential price
increases. To the extent there are increases in the company's steel costs, they
are generally recaptured in the company's product sales prices.

Aluminum hedge contracts of less than one year duration are purchased to hedge
the engineered products backlog of the Vistawall group against potential losses
caused by increases in aluminum costs. This product line is sensitive to
material cost movements due to the longer lead times from project quoting to
manufacture. Gains or losses recorded on hedge contracts are offset against the
actual aluminum costs incurred. The change in fair value of aluminum contracts
and their associated risk are immaterial.

The company's wood frame building business enters into forward purchase
arrangements for commercial grade lumber for periods of less than one year
duration. Lumber costs are generally more volatile than steel costs. To offset
increases in lumber costs, the company adjusts product prices accordingly.

Interest Rates: The majority of the company's long-term debt carries a fixed
interest rate, therefore the company's interest expense is relatively stable and
not influenced by changes in market interest rates.

Foreign Currency Fluctuation: The majority of the company's business is
transacted in U.S. dollars, therefore limiting the company's exposure to foreign
currency fluctuations. Where the company has foreign-based operations, the local
currency has been adopted as the functional currency. As such, the company has
both transaction and translation foreign exchange exposure in those operations.
Due to relative cost and limited availability, the company does not hedge its
foreign net asset exposure. The company does hedge short-term foreign currency
transaction exposures related to sales activity in Canada. Forward Canadian
dollar sale contracts of less than one year duration are purchased to cover the
exposure. The change in fair value of such contracts are immaterial.

OTHER
The company announced that Donald H. Pratt, chairman of the board will retire at
the end of the year. John J. Holland, president and chief executive officer,
will succeed Mr. Pratt. Ronald E. Rutledge, currently executive vice president,
will become president and chief operating officer.

ITEM 2.  CHANGES OF SECURITIES AND USE OF PROCEEDS

On June 27, 2001 the Company issued $50.0 million of its 7.87% Senior Notes due
December 30, 2016 pursuant to a note purchase agreement dated as of June 20,
2001. It requires the Company to maintain adjusted consolidated net worth, as
defined, of $125 million plus the cumulative sum of 50% of consolidated net
income for each fiscal quarter after March 31, 2001, and a consolidated income
available for fixed charges to fixed charge ratio, as defined, of 1.5 to 1.0. At
