         net income per share includes all dilutive common stock
         equivalents in the weighted average shares outstanding. The
         reconciliation between basic and diluted earnings per share

         5.  ACQUISITIONS

         On December 1, 1999, the Company purchased all the
         outstanding capital stock of Hughes Manufacturing,
         Inc.(Hughes)for approximately $11.5 million in cash.
         Hughes manufactures a broad line of fully engineered, code-
         approved steel lumber connectors and other metal hardware
         products.

         On November 1, 1999, the Company purchased all the
         outstanding capital stock of Brazing Concepts Company
         (Brazing Concepts) for approximately $25 million in cash.
         Brazing Concepts provides a wide variety of value-added
         brazing (i.e., metal joining), assembly and other
         metallurgical heat treating services on customer-owned
         materials.

         On August 1, 1999, the Company purchased the assets and
         business of Hi-Temp Incorporated (Hi-Temp) for
         approximately $24 million in cash.
         Hi-Temp provides metallurgical heat treating services in
         which customer-owned parts are exposed to precise
         temperature and other conditions to improve their material
         properties, strength and durability.


                                7 of 12

         On July 1, 1999, the Company purchased all the outstanding
         capital stock of K & W Metal Fabricators, Inc. d/b/a
         Weather Guard Building Products (Weather Guard) for
         approximately $7 million in cash.  Weather Guard
         manufactures a full line of metal building products,
         including rain-carrying systems, metal roofing and roofing
         accessories, for industrial, commercial and residential
         applications.

         These acquisitions have been accounted for under the
         purchase method with the results of their operations
         consolidated with the Company's results of operations from
         the respective acquisition dates. The aggregate excess of
         the purchase prices of these acquisitions over the fair
         market values of the net assets of the acquired companies
         is being amortized over 35 years from the acquisition dates
         using the straight-line method.

         The following information presents the pro forma
         consolidated condensed results of operations as if the
         acquisitions had occurred on January 1, 1999.
         The pro forma amounts may not
         be indicative of the results that actually would have been
         achieved had the acquisitions occurred as of January 1,
         1999 and are not necessarily indicative of future results
         of the combined companies.

         Item 2.  Management's Discussion and Analysis of Financial
         Condition and Results of Operations


         Results of Operations

         Net sales increased $23.8 million, or 16.6%, to $167.6
         million for the first quarter ended March 31, 2000 from
         $143.8 million for the prior year's first quarter. This
         increase resulted from including net sales of Weather Guard
         (acquired July 1, 1999), Hi-Temp (acquired August 1, 1999),
         Brazing Concepts (acquired November 1, 1999)and Hughes
         (acquired December 1, 1999)(collectively, the Acquisitions)
         together with sales growth at existing operations.

         Cost of sales as a percentage of net sales decreased to
         79.4% for the first quarter of 2000 from 80.2% in 1999.
         This improvement was primarily due to the Acquisitions,
         which have historically generated higher margins than the
         Company's existing operations.

         Selling, general and administrative expenses as a
         percentage of net sales increased to 12.1% for the first
         quarter of 2000 from 11.6% for the same period of 1999.
         This increase was primarily due to higher costs as a
         percentage of sales attributable to the Acquisitions and
         performance based compensation linked to the Company's
         sales and profitability.

         Interest expense increased $.9 million from 1999 to 2000
         primarily due to higher borrowings in 2000 related to the
         four acquisitions completed during the second half of 1999,
         and a higher effective borrowing rate in 2000.

         As a result of the above, income before taxes increased by
         $1.7 million for the first quarter ended March 31, 2000
         compared to 1999.

         Income taxes approximated $4.1 million and $3.4 million for
         the first quarter of 2000 and 1999, respectively, based on
         an effective tax rate of 40.5% in both periods.


         Liquidity and Capital Resources

         During the first three months of 2000, the Company's
         working capital increased by $12.5 million to $125.5
         million.  Additionally, shareholders' equity increased by
         $5.8 million at March 31, 2000 to $191.2 million.

         The Company's principal capital requirements are to fund
         its operations, including working capital, the purchase and
         funding of improvements to its facilities, machinery and
         equipment and to fund acquisitions.

         Net income of $6.0 million and depreciation and
         amortization of $5.1  million combined with an increase in
         accounts payable and accrued expenses of $5.4 million to
         provide cash of $16.5 million.  This was primarily offset
         by $18.2 million used for working capital purposes to
         service increased sales levels.




                                9 of 12

         During the first three months of 2000, $7.1 million of net
         proceeds from the sale of property and equipment and $1.7
         million of cash on hand at the beginning of the period were
         used to fund operations, capital expenditures of $5.3
         million and cash dividends of $.3 million, and to reduce
         long-term debt by $1.1 million.

         At March 31, 2000 the Company's aggregate credit facilities
         available approximated $280 million, with borrowings of
         approximately $230 million and an additional availability
         of approximately $50 million.

         The Company believes that availability of funds under its
         credit facilities together with cash generated from
         operations will be sufficient to provide the Company with
         the liquidity and capital resources necessary to support
         its existing operations.


         Recent Accounting Pronouncement

         In June 1998, the Financial Accounting Standards Board
         issued Statement of Financial Accounting Standards No. 133
         Accounting for Derivative Instruments and Hedging
         Activities (FAS No. 133) which requires recognition of the
         fair value of derivatives in the statement of financial
         position, with changes in the fair value recognized either
         in earnings or as a component of other comprehensive income
         dependent upon the hedging nature of the derivative.
         Implementation of FAS No. 133 is required for fiscal 2001.
         The Company does not believe that FAS No. 133 will have a
         material impact on its earnings or other comprehensive
         income.


         Safe Harbor Statement

         The Company wishes to take advantage of the Safe Harbor
         provisions included in the Private Securities Litigation
