BUSCH CO. NOTES TO FINANCIAL STATEMENTS DECEMBER 31, 1996 NOTE 1 - ORGANIZATION Busch Co. (the Company) designs and manufactures air handling units for the metals industry. Also, they are manufacturer's representatives for vendors that supply components related to this industry. The customer base includes steel and aluminum producers worldwide and the Company extends credit to these customers. The Company performs ongoing credit evaluations of its customers' financial condition and, generally, requires no collateral from its customers. NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES A summary of significant accounting policies consistently applied by management in the preparation of the accompanying financial statements follows. Revenue recognition - Revenue from contracts is recognized on the percentage of completion method as more fully described below. Revenue from sales of product related to the Company's service representative and distributor relationships is generally recognized upon shipment to customers. Management estimates - The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Cash - The Company maintains cash deposits in various banks which at times exceed federally insured amounts. Inventory - Cost is stated at the lower of cost or market. Cost is determined using the first-in, first- out (FIFO) method. Property and equipment - Depreciation is provided on the straight-line method over estimated useful lives. Repairs and maintenance which do not extend the lives of the applicable assets are charged to expense as incurred. Profit or loss resulting from the retirement or other disposition of assets is included in income. Patent - Included in other assets in the accompanying balance sheet is approximately $85,000 related to patent costs. Amortization is provided on the straight-line basis over estimated useful lives and accumulated amortization approximated $8,000 at December 31, 1996. Contracts - Revenues from the design and manufacture of air handling units are recognized on the percentage of completion method, measured by the percentage of contract costs incurred to date to estimated total contract costs for each contract. This method is used because management considers contract costs to be the best available measure of progress on these contracts. 5

BUSCH CO. NOTES TO FINANCIAL STATEMENTS DECEMBER 31, 1996 NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued) Contract costs include direct material, labor cost and those indirect costs related to contract performance, such as indirect labor, supplies, tools, repairs and depreciation costs. General and administrative costs are charged to expense as incurred. Provisions for estimated losses on uncompleted contracts are made in the period in which such losses are determined. Changes in job performance, job conditions and estimated profitability may result in revisions to contract revenue and costs and are recognized in the period in which the revisions are made. The asset, "costs and estimated earnings in excess of billings on uncompleted contracts," represents revenues recognized in excess of amounts billed, the liability, "billings in excess of costs and estimated earnings on uncompleted contracts," represents billings in excess of revenues recognized. Income taxes - The corporation has elected to be taxed as an S corporation. Accordingly, the taxable income or loss of the corporation is included in the personal tax returns of the stockholders. Therefore, no provision for federal or state income taxes is included in the accompanying financial statements. NOTE 3 - SUBSEQUENT EVENT In 1997, the Company entered into a letter of intent which provides for the transfer of certain assets, and all rights and interests of the Company. As of the date of this report, no agreements have been consummated. NOTE 4 - FAIR VALUE OF FINANCIAL INSTRUMENTS The carrying amounts of the Company's cash and cash equivalents, accounts receivable and note payable approximate their fair value.

BUSCH CO. NOTES TO FINANCIAL STATEMENTS DECEMBER 31, 1996 NOTE 9 - EMPLOYEE RETIREMENT PLANS The Company has a defined contribution profit sharing plan covering substantially all full-time employees.

NOTE 10 - LEASES The Company leases its corporate offices from an entity related through common ownership. The lease provides for monthly rental payments of approximately $11,000 and is due to expire on July 31, 1999. In addition, the Company also leases automobiles and certain office equipment. Total rent expense approximated $203,000 for the year ended December 31, 1996. Following is a schedule, by year, of the future minimum rental payments required under operating leases that have initial or remaining noncancelable lease terms in excess of one year as of December 31, 1996: 1997 $214,000 1998 198,000 1999 103,000 2000 13,000 2001 2,000 -------- $530,000 ======== NOTE 11 - BACKLOG The following schedule shows a reconciliation of backlog representing the amount of revenue the Company expects to realize from work to be performed on uncompleted contracts in progress at December 31, 1996 and from contractual agreements on which work has not yet begun: Balance, December 31, 1995 $ 4,763,531 Contract adjustments 45,123 New contracts, 1996 10,930,030 ------------ 15,738,684 Less contract revenue recognized, 1996 9,347,755 ------------ Balance, December 31, 1996 $ 6,390,929 ============ As of December 31, 1996, certain contracts have been omitted from the backlog reconciliation due to management's uncertainty as to the continuation of these contracts. The total contract price, contract revenue recognized during 1996 and backlog associated with these contracts, amounted to approximately $2,547,000, $104,000 and $2,443,000, respectively. In addition, between January 1, 1997 and June 30, 1997, the Company entered into additional contracts with a value of approximately $6,880,000. 8
