              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                     Six Months Ended June 30, 2001 and 2000

(1)   The accompanying unaudited condensed consolidated financial statements
      include the accounts of Carlisle Companies Incorporated and its
      wholly-owned subsidiaries (together, the "Company"). Intercompany
      transactions and balances have been eliminated in consolidation. The
      unaudited condensed consolidated financial statements have been prepared
      in accordance with Article 10-01 of Regulation S-X of the Securities and
      Exchange Commission and, as such, do not include all information required
      by generally accepted accounting principles. However, in the opinion of
      the Company, these financial statements contain all adjustments,
      consisting of only normal recurring adjustments, necessary to present
      fairly the financial statements for the interim period presented herein.
      Results of operations for the three months and six months ended June 30,
      2001 are not necessarily indicative of the operating results for the full
      year.

      While the Company believes that the disclosures presented are adequate to
      make the information not misleading, it is suggested that these financial
      statements be read in conjunction with the financial statements and notes
      included in the Company's 2000 Annual Report to Stockholders and 2000 Form
      10-K.

(3)   On June 29, 2001, upon expiration of its $200 million 364-Day Revolving
      Credit Facility, the Company renewed the 364-Day facility and increased
      the amount available to $225 million.

(4)   The Company has recently completed several acquisitions and has
      tentatively considered the carrying value of the acquired assets to
      approximate their fair value, with all of the excess of those acquisition
      costs being attributable to goodwill. The Company is in the process of
      fully evaluating the assets acquired and, as a result, the purchase price
      allocation among the tangible and intangible assets acquired and their
      useful lives may change.

(5)   Diluted earnings per share of common stock are based on the weighted
      average number of shares outstanding of 30,494,023 for the three months
      ended June 30, 2001 and 30,499,166 for the six months ended June 30, 2001,
      assuming the exercise of dilutive stock options.

(6)   RECENT ACCOUNTING STANDARDS -

      Effective January 1, 2001, the Company implemented SFAS No. 133,
      "Accounting for Derivative Instruments and Hedging Activities". This
      statement standardizes the accounting for derivatives and hedging
      activities and requires that all derivatives be recognized in the
      statement of financial position as either assets or liabilities at fair
      value. Changes in the fair value of derivatives that do not meet the hedge
      accounting criteria are to be reported in earnings. Implementation of this
      pronouncement did not have a material effect since the Company has not
      utilized derivative financial instruments or entered into hedging
      transactions.

      In June 2001, the Financial Accounting Standards Board (FASB) issued
      Statement of Financial Standards (SFAS) Number 141, "Business
      Combinations" which establishes that all business combinations be
      accounted for by the purchase method of accounting and establishes new
      standards for recognizing goodwill and intangible assets. Under the
      provisions of this pronouncement, an intangible asset is recognized apart
      from goodwill if it arises from contractual or other legal rights or if it
      is separable. The Statement applies to all business combinations initiated
      after June 30, 2001 and to all business combinations accounted for by the
      purchase method of accounting for which the acquisition date is July 1,
      2001 or later. Additionally, this Statement requires that the provisions
      regarding the recognition of goodwill and intangibles under SFAS 142 be
      applied to its business combinations accounted for by the purchase method
      of accounting for which the acquisition date was prior to July 1, 2001.

      In June 2001, the FASB also issued SFAS 142, "Goodwill and Other
      Intangible Assets" which establishes new standards for how goodwill and
      other intangible assets are to be accounted for subsequent to their
      acquisition. This statement must be adopted by the company January 1,
      2002. Under this statement, goodwill is classified as an infinite-lived
      asset and is no longer subject to amortization but rather will be
      evaluated on at least an annual basis for impairment based on fair-value.
      To comply with the provisions of this statement, the Company is required
      to reassess the useful lives of its intangible assets acquired on or
      before June 30, 2001. The Company will also be required to perform
      impairment tests on all goodwill recorded as of January 1, 2002 and record
      any impairment charges by December 31, 2002. Additionally, in the initial
      period of adoption and in each subsequent period thereafter until all
      periods presented are consistent with the provisions of this
      pronouncement, the Company is required to present adjusted net income for
      prior periods. The Company is currently evaluating what impact SFAS 141
      and SFAS 142 will have on its results of operations.

(7)   In the first quarter of 2001, the Company recorded a restructuring charge
      of $37.7 million ($24.0 million after tax or $0.79 per diluted share)
      primarily composed of costs to exit and realign facilities that have
      under-performed in the automotive components and transportation
      businesses. Included in this total are facility closures and write-downs
      of property, plant and equipment, inventory and goodwill of $29.5 million
      and severance and other employee costs of $8.2 million. As of June 30,
      2001, payments of $0.9 million have been made for these charges. The
      Company anticipates that the remaining costs and actions required to exit
      and realign these operations will be completed by the end of the first
      quarter of 2002.

      For facilities to be closed, the tangible assets to be disposed of have
      been written down to their estimated fair value, less cost of disposal.
      All intangible assets associated with the facility closures have been
      evaluated and the carrying value of goodwill adjusted if necessary. The
      carrying value of intangible assets was evaluated based upon expected
      future operating cash


                                  Page 6 of 12
<Page>

      flows. Considerable management judgment is necessary to estimate fair
      value, accordingly, actual results could vary significantly from such
      estimates. The restructuring initiative provides for a reduction of
      approximately 980 employees related to position eliminations from the
      facility closures and streamlining of operations. As of June 30, 2001,
      approximately 40% of these reductions have been made.

                     MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                  FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Carlisle Companies Incorporated ("Carlisle" or the "Company") reported record
sales of $490.4 million, up 2% over 2000. Net earnings of $16.6 million or $0.54
per share (diluted), compared to $1.04 per share in the second quarter 2000.
Second quarter sales were driven by increased volume in the Construction
Materials segment and growth through acquisition in the General Industry
segment. The reduction in earnings is primarily attributable to the continued
decline in demand at operations serving transportation, telecommunications, and
outdoor power equipment markets. As the slow market conditions experienced in
the beginning of the year continued into the second quarter, Carlisle management
reduced production at several manufacturing operations in order to control
inventory levels. Diminished absorption of fixed costs on lower production,
continued pricing pressures to maintain market share, and higher utility and raw
material costs were the primary factors responsible for the lower gross margin.
Manufacturing costs continued to receive the utmost attention and cost reduction
programs continued. However, the favorable impact of these initiatives was more
than offset by lower production levels. Acquisitions made in the last twelve
months contributed $27 million of sales growth and $.4 million of earnings.

Net sales in the first half of 2001 were $953.6 million, a 4% increase over
2000. Current year to date net earnings of $6.4 million or $0.21 per share,
include the $24.0 million or $0.79 per share, after tax restructuring charge
recorded in the first quarter. After factoring out the effect of the
restructuring charge, net earnings from operations were $30.4 million or $1.00
per share. This result compares to $1.87 per share over the same period in 2000.

Construction Materials sales of $130 million in the second quarter increased 29%
over 2000 second quarter sales of $101 million. The increase was primarily in
the domestic roofing market on higher shipments of rubber membrane and
accessories, thermoplastic polyolefin (TPO) roofing membrane, and insulation
shipments. Although operating earnings improved 9% over last year the increase
did not keep pace with sales. Steps implemented in 2000 to reduce selling and
administrative costs had a positive impact on current year operating costs, but
did not offset the market pressures on selling prices, and increased raw
material costs. Comparative results were also impacted by stronger sales of
lower margin products.

Industrial Component sales decreased 8% from the second quarter 2000 with
operating earnings down 58%. Most of the change was the result of lower sales
and earnings at Carlisle Tire & Wheel Company. Shipments to original equipment
customers were significantly off when compared to a year ago, particularly in
the lawn and garden markets. As a result of the sharp decline in orders from
these customers, CT&W reduced production throughout many of its operations. In
addition, competitive pricing pressures in other markets, and rising energy and
raw material costs negatively impacted operating earnings. Carlisle Industrial
Brake & Friction and Motion Control also reported lower sales and earnings. The
market softness experienced during the first quarter in the heavy duty truck,
heavy construction and mining equipment markets continued into the second
quarter. Sales at Tensolite were up in the second quarter as a result of the
acquisition of UniTrek, in July 2000, and Connecting Devices, in March of this
year. Tensolite earnings continued to be negatively impacted by softness in the
telecommunications market.

Automotive Components sales for the quarter were down 12%, which reflect lower
automotive build levels. Operating earnings of $4.2 million, decreased 39% as
compared to the same period last year as production levels were adjusted to
coincide with softer demand. The benefits of reduced overhead and labor costs,
as a result of the restructuring charge recorded in the first quarter, were more
than offset by the under absorption of fixed costs due to lower production
levels.

General Industry sales of $121 million were up 6% over the second quarter 2000,
while operating earnings were down 55%. Reduced production volume at most of the
operations in this business segment was the primary factor behind the
deterioration in earnings. Excluding the contribution of acquisitions,
Transportation Products net sales were below the second quarter 2000, and
earnings declined due to competitive pricing, unabsorbed fixed costs associated
with lower production levels, and increased utility costs. Carlisle FoodService
sales and earnings were down from last year as consumer discretionary spending
continued to be limited due to the uncertainty in the economy. Lower sales,
coupled with production cutbacks, are the primary factors causing the decrease
in earnings. Sales at Carlisle Systems & Equipment increased primarily as a
result of acquisitions completed over the last nine months. Earnings in this
business have been negatively impacted by depressed conditions in the perishable
food delivery markets served by Johnson Truck Bodies.

CASH FLOWS

Cash flow from operations in the second quarter was $37 million, up from $35
million in 2000. For the six months ended June 30, 2001, cash generated from
operations of $56 million was equal to a year ago. The increase for the quarter
was attributable to working capital improvements as demonstrated by a $28
million reduction in inventory. Higher receivable balances, principally due to
special dating programs in the roofing business, dampened working capital
improvements.

BACKLOG

The June 30, 2001 backlog of $290 million was 10% over June 30, 2000 of $264
million. Improved backlog positions at Tensolite and Carlisle Systems &
Equipment were driven by acquisitions and increased market demand.

FIRST QUARTER 2001 RESTRUCTURING UPDATE

In the first quarter of 2001, the Company recorded a $24.0 million after tax, or
$0.79 per share, restructuring charge to earnings. The $24.0 million after tax
restructuring charge was primarily (84%) composed of costs related to exiting
and realigning facilities that had under performed in the automotive components
and transportation businesses and were not forecasted to perform at our
standard. Approximately $18.8 million after tax (78%) of the total charge is
related to machinery, equipment, inventory and goodwill write-offs. The
remainder of $5.2 million after tax represents anticipated cash expenses from
involuntary employee terminations and other restructuring costs. The Company is
proceeding with the exit and realignment of certain facilities and expects to
have these actions completed by the first quarter of 2002. To date, 40% of the
workforce reductions have taken place. The Company expects the future savings of
reduced depreciation and employee expense to approximate $1.8 million, or $0.06
per share, on an annual basis.

ITEM 3.     QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISKS.

            The Company has not utilized derivative financial instruments or
            derivative commodity instruments in its cash and cash equivalents.
            Our transactions are predominantly conducted, and our accounts are
            primarily denominated, in United States dollars. Accordingly, the
            Company had limited exposure to significant foreign currency risk.
            Even so, our financial results could be significantly affected by
            factors such as changes in foreign currency exchange rates or weak
            economic conditions in our markets.
