INDEPENDENT AUDITORS' REPORT

Motor Products—Owosso Corporation and Motor Products—Ohio Corporation
Michigan, Ohio

        We have audited the accompanying combined balance sheets of Motor Products—Owosso Corporation and Motor Products—Ohio Corporation (the "Company"), wholly-owned subsidiaries of Owosso Corporation (the "Parent") as of October 28, 2001 and October 29, 2000, and the related combined statements of income, stockholder's equity, and cash flows for each of the two fiscal years ended October 28, 2001. These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements based on our audits.

        We conducted our audits in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

        In our opinion, such combined financial statements present fairly, in all material respects, the financial position of the Company as of October 28, 2001 and October 29, 2000 and the results of its operations and its cash flows for the two fiscal years ended October 28, 2001 in conformity with accounting principles generally accepted in the United States of America.

        As discussed in Notes 3 and 6, certain expenses included in the Company's financial statements represent allocations of amounts incurred by the Parent. As a result, the financial statements may not be indicative of conditions that would have existed or results that would have occurred had the Company operated as an unaffiliated entity.

        The accompanying financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 2 to the financial statements, the Company, along with the Parent and various other wholly-owned subsidiaries of the Parent, collectively referred to as the "Co-Borrowing Group," is a party to a lending agreement with banks whereby the Company and each other member of the Co-Borrowing Group are jointly and severally liable for repayment of the borrowings under the lending agreement, the Parent's recurring losses from operations, working capital deficiency, default under terms of its credit agreement, and inability to comply with the covenants of its credit agreement raise substantial doubt about the Company's ability to continue as a going concern. Management's plans concerning these matters are also described in Note 2. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.

MOTOR PRODUCTS—OWOSSO CORPORATION AND
MOTOR PRODUCTS—OHIO CORPORATION

NOTES TO COMBINED FINANCIAL STATEMENTS

FISCAL YEARS ENDED OCTOBER 28, 2001 AND OCTOBER 29, 2000

1. NATURE OF BUSINESS

        The Company—The combined financial statements represent the combined financial position, results of operations and cash flows of Motor Products—Owosso Corporation and Motor Products—Ohio Corporation (collectively, "Motor Products" or "the Company"). The Company is a wholly-owned subsidiary of Owosso Corporation (the "Parent"). The Company manufactures fractional and integral horsepower motors. Significant markets include commercial products and equipment, healthcare, recreation, and non-automotive transportation.

2. LIQUIDITY AND FINANCING

        The Company, along with the Parent and various other wholly-owned subsidiaries of the Parent, collectively referred to as the "Co-Borrowing Group", is a party to a lending agreement with banks, which provide the Co-Borrowing Group with a $24,000,000 revolving credit facility, of which approximately $2,000,000 was available as of October 28, 2001. As of April 28, 2002, $17,700,000 (unaudited) was outstanding under the Co-Borrowing Group's revolving credit facility. To date, all borrowings under the revolving credit facility have been made by the Parent. Accordingly, the full amount of the outstanding borrowing is reflected on the Parents' financial statements and none of such borrowings are reflected on the financial statements of the Company or other subsidiaries of the Parent. However, under the terms of the revolving credit facility, the Parent, the Company and each other subsidiary of the Parent are jointly and severally liable for the borrowings. Substantially all the assets and the common stock of the Company secure the Parent's borrowings.

        The revolving credit facility between the banks and the Co-Borrowing Group was entered into on January 22, 1999, and was to originally expire in December 2002. The agreement included financial and other covenants, including fixed charge, cash flow and net worth ratios and restrictions on certain asset sales, mergers and other significant transactions. The Co-Borrowing Group was not in compliance with such covenants at October 29, 2000. In February 2001, the Co-Borrowing Group entered into an amendment to its revolving credit facility, wherein the lenders agreed to forbear from exercising their rights and remedies under the facility in connection with such non-compliance until February 15, 2002, at which time the facility was to mature. The amendment to the revolving credit facility, which has been further amended since February 2001, called for reductions in the outstanding balance during calendar 2001 and modified the interest rates charged. Borrowings under the revolving credit facility that are In-Formula (as defined) are charged interest at the Prime Rate plus 1.5% (7.0% at October 28, 2001). Borrowings under the revolving credit facility that are Out of Formula (as defined) are charged interest at the Prime Rate plus 2.0% (7.5% at October 28, 2001). Borrowings and letters of credit are limited to a Borrowing Base, consisting of eligible accounts receivable and inventory. Borrowings that equal an amount up to and including the Borrowing Base, will be defined as In-Formula borrowings. Total borrowings less In-Formula borrowings, are defined as Out of Formula borrowings. The amendment required additional collateral, effectively all of the assets of the Co-Borrowing Group, and reporting requirements, as well as, the addition of a covenant requiring minimum operating profits. The amendment also required the suspension of principal and interest payments on subordinated debt of the Parent, with an aggregate outstanding balance of $2,046,000 at October 28, 2001. Furthermore, the amendment to the revolving credit facility prohibits the payment of preferred or common stock dividends by the Parent. Beginning in August 2001, the Co-Borrowing Group was not in compliance with the minimum operating profit covenant. In February 2002, the

9

---

Co-Borrowing Group entered into a further amendment to the revolving credit facility which extends the maturity date to December 31, 2002. The amendment calls for reductions in the outstanding balance based on expected future asset sales, increases the interest rate charged and requires minimum EBITDA.

        In addition, the Parent has experienced significant losses from operations in each of the past two fiscal years.

        Summarized financial information of the Co-Borrowing Group as of October 28, 2001 and for the fiscal year then ended follows:

        The accompanying combined financial statements of the Company have been prepared on a going concern basis of accounting and do not reflect any adjustments that might result if the Company is unable to continue as a going concern. The Company and each other member of the Co-Borrowing Group are liable jointly and severally for repayment of the borrowings under the Parent's revolving credit loan, the Parent's recurring losses from operations, working capital deficiency, default under the terms of its revolving credit agreement and inability to comply with debt covenants raise substantial doubt about the Company's ability to continue as a going concern.

        Since the second half of fiscal 2000, management of the Parent has taken a series of steps intended to stabilize and improve the operating results of the Parent, including disposition of several unprofitable operations, the implementation of cost and personnel reductions at the corporate office and reductions in fixed costs of the remaining operating units, commensurate with reductions in sales volume. In October 2001, the Parent's corporate staff was reduced from nine individuals to four and the Parent's president and chief executive officer agreed to a 20% reduction in salary. In addition, the Parent intends to further reduce corporate office costs through the merger of the corporate office

10

---

function into the Parent's largest subsidiary, resulting in an expected savings of approximately $3.5 million.

        The Parent intends to dispose of the Company and certain other assets. Proceeds from these sales, which are expected to be between $12.0 and $14.0 million will be utilized to reduce the Co-Borrowing Group's revolving credit facility and secure, for the Company, a release from any further obligation under the terms of the lending agreement with the Banks (See Note 12). There can be no assurance that any asset sales will be finalized.

        Management believes that, with the sale of assets, available cash and cash equivalents, cash flows from operations and available borrowings under the Co-Borrowing Group's revolving credit facility will be sufficient to fund the Parent's remaining operating and investing activities and the debt maturities for fiscal 2002. In addition, management believes that the Co-Borrowing Group will be in compliance with its debt covenant requirements throughout fiscal 2002. It is management's intent to refinance the Co-Borrowing Group's revolving credit facility prior to its maturity in December 2002. However, there can be no assurance that management's plans will be successfully executed.

3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

        Basis of Presentation—The combined financial statements of the Company include the accounts of Motor Products—Owosso Corporation and Motor Products—Ohio Corporation. The Company does not maintain stand-alone corporate, human resources, finance or similar support functions; therefore, certain expenses related to these functions included in the financial statements represent allocations of amounts incurred by the Parent. Such allocations of the Parent's direct costs are based principally on actual expenses or other applicable activity, which management believes is a reasonable allocation method. The Company believes that such allocations may not necessarily be indicative of the conditions that would have existed or results that would have occurred if the Company had operated as an unaffiliated entity. Allocated costs were $809,000 and $856,000 for 2001 and 2000, respectively. See Note 6 for additional information. All intercompany accounts, transactions, and profits have been eliminated.

        Fiscal Year—The Company's fiscal year consists of the 52 or 53 weeks ending on the last Sunday in October. Both fiscal year 2001 and 2000 consisted of 52 weeks.

        Cash and Cash Equivalents—Cash and cash equivalents consist of cash and highly liquid investments with an original maturity of three months or less.

        Inventories—Inventories of the Company are recorded at lower of cost or market. At October 28, 2001 and October 29, 2000, cost for 56% and 63%, respectively, of the inventories was determined on the last-in, first-out (LIFO) basis, and the remainder on the first-in, first-out (FIFO) basis.

        Information related to the FIFO method may be useful in comparing operating results to those of companies not on LIFO. If the FIFO method of inventory, which approximates replacement cost, had been used by the Company for all inventories, inventory would have been approximately $746,000 and $790,000 higher than reported at October 28, 2001 and October 29, 2000, respectively. Additionally, income from operations would have decreased by approximately $44,000 and $13,000 in 2001 and 2000,

11

---

respectively. These amounts reflect the combined effects, in each year, of changes in inventory quantities and unit costs.

        Property, Plant and Equipment—Items of property, plant and equipment are stated at cost and are depreciated principally on the straight-line method over their estimated useful lives as follows:

        Use of Estimates—The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America 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 may differ from those estimates and assumptions.

        Asset Impairment—The Company evaluates the carrying value of long-term assets based upon current and anticipated undiscounted cash flows, and recognizes an impairment when such estimated cash flows will be less than the carrying value of the asset. Measurement of the amount of impairment, if any, is based upon the difference between carrying value and fair value.

        Revenue Recognition—Revenue is recognized at the time the product is shipped and title of ownership has passed.

        Income Taxes—Deferred income taxes are determined based on the difference between the financial reporting and tax bases of assets and liabilities. Deferred income tax expense represents the change during the reporting period in the deferred tax assets and deferred tax liabilities, net of the effect of acquisitions and dispositions. Deferred tax assets include tax loss and credit carryforwards and are reduced by a valuation allowance if, based on available evidence, it is more likely than not that some portion or all of the deferred tax assets will not be realized.

        New Accounting Pronouncements—In July 2001, the Financial Accounting Standards Board issued SFAS No. 141, Business Combinations, and SFAS No. 142, Goodwill and Other Intangible Assets. SFAS No. 141 requires business combinations initiated after June 30, 2001 to be accounted for using the purchase method of accounting, and broadens the criteria for recording intangible assets separate from goodwill. Recorded goodwill and intangibles will be evaluated against this new criteria and may result in certain intangibles being subsumed into goodwill, or alternatively, amounts initially recorded as goodwill may be separately identified and recognized apart from goodwill. SFAS No. 142 requires the use of a nonamortization approach to account for purchased goodwill and certain intangibles. Under a nonamortization approach, goodwill and certain intangibles will not be amortized into results of operations but, instead, would be reviewed for impairment and written down and charged to results of operations only in the periods in which the recorded value of goodwill and certain intangibles is more than its fair value. The provisions of each statement which apply to goodwill and intangible assets acquired prior to June 30, 2001 are required to be adopted for fiscal years beginning after December 15, 2001. The Company has not yet completed its analysis of the effects of adopting these statements on its combined financial position or results of operations.

12

---

        In August 2001, the Financial Accounting Standards Board issued SFAS No. 144, Accounting for the Impairment or Disposal of Long-Lived Assets. SFAS No. 144, which addresses financial accounting and reporting for the impairment of long-lived assets and for long-lived assets to be disposed of, supersedes SFAS No. 121 and is effective for fiscal years beginning after December 15, 2001. The Company has not yet completed its analysis of the effects of adopting the statement on its combined financial position or results of operations.

        In June 1998, the Financial Accounting Standards Board issued SFAS No. 133, Accounting for Derivative Instruments and Hedging Activities. This statement establishes accounting and reporting standards for derivative instruments, (including certain derivative instruments embedded in other contracts collectively referred to as derivatives), and for hedging activities. It requires that entities recognize all derivatives as either assets or liabilities in the statement of financial position and measure those assets or liabilities at fair value. SFAS No. 133 was amended in June 2000 by SFAS No. 138, Accounting for Certain Derivative Instruments and Certain Hedging Activities, which addressed a limited number of issues causing implementation difficulties. SFAS No. 133, as amended, is effective for years beginning after June 15, 2000. The Company adopted SFAS No. 133 as of October 30, 2000. There was no transition adjustment impact upon adoption and there has been no impact on reported results since adoption.

4. INVENTORIES

        Inventories consist of the following at December 31, 2001 and 2000:

13

---

5. PROPERTY, PLANT AND EQUIPMENT

        Property, plant and equipment consists of the following at December 31, 2001 and 2000:

6. RELATED PARTY TRANSACTIONS

        At the end of each accounting period, the Company's net cash on its main disbursement and lock box accounts is reduced to $0 through either a forwarding to the Parent or a loan from the Parent. These balances are classified in stockholder's equity. As of April 28, 2002 (unaudited), October 28, 2001 and October 29, 2000, the Company has made net advances to the Parent in the amounts of $8,310,000 (unaudited), $7,230,000 and $6,237,000, respectively. No interest is charged to the Parent on these advances and there is no contractual due date.

        The Parent charges a corporate fee to all of its subsidiaries equal to 3% of net sales. Such fee is charged to cover corporate salary and benefit costs, corporate overhead costs, legal and professional and other costs incurred at the Parent level. For 2001 and 2000, corporate expenses allocated to the Company totaled $759,000 and $806,000, respectively. In addition, the Parent charged the Company with $50,000 of other items in both 2001 and 2000.

        Expenses for insurance and information technology are allocated from corporate based on the actual costs for the subsidiary. For 2001 and 2000, insurance and information technology costs allocated to the Company totaled approximately $455,000 and $197,000, respectively. These expenses are included in cost of products sold and selling, general and administrative expenses in the combined statements of income.

        The Company has made sales of $88,000 and $98,000 to one of Parent's other subsidiaries in 2001 and 2000, respectively. These balances were recorded at cost.

7. LONG-TERM DEBT

        Long-term debt consists of the following at December 31, 2001 and 2000:

        The aggregate amount of required payments on long-term debt is as follows:

8. PENSION PLAN

        Pension Plans—The Parent sponsors a defined contribution 401(k) plan covering substantially all of its employees, except for Motor Products' hourly union employees, who are covered under the defined benefit pension plan described below. Eligible employees may contribute up to 15% of their compensation to this plan and their contributions are matched by the Parent at a rate of 50% on the first 4% of the employees' contributions. The plan also provides for a fixed contribution of 3% of eligible employees' compensation. Pension expense related to this plan was $146,000 and $138,000 for 2001 and 2000, respectively.

        Motor Products has a defined benefit pension plan covering substantially all of its hourly union employees. The benefits are based on years of service, the employee's compensation during the last three years of employment, and accumulated employee contributions.

The Company recognizes the expected cost of providing such post-retirement benefits during an employee's active service period.

        The following tables provide a reconciliation of the change in the accumulated postretirement benefit obligation and the net amount recognized in the combined balance sheets:

17

---

        Net periodic postretirement benefit cost included the following components:

        For measurement purposes, a 10% annual rate of increase in the per capita cost of covered health care benefits was assumed. The rate was assumed to decrease gradually to 4.5% for 2012, and remain at that level thereafter. The healthcare cost trend rate assumption has a significant effect on the amounts reported. To illustrate, increasing the assumed healthcare cost trend rates by one percentage point in each year would increase the accumulated postretirement benefit obligation as of October 28, 2001 by $551,000 and the aggregate of the service cost and interest cost components of the net periodic postretirement benefit cost for the year then ended by $78,000. Decreasing the assumed healthcare postretirement benefit obligation as of October 28, 2001 by 1% decreases the accumulated postretirement benefit obligation by $418,000 and the aggregate of the service cost and interest cost components of the net periodic postretirement benefit cost for the year then ended by $57,000. The weighted average discount rate used in determining the accumulated postretirement benefit obligation was 6.5% as of October 28, 2001 and 7.5% as of October 29, 2000.

9. COMMITMENTS AND CONTINGENCIES

        The Company is jointly and severally liable for borrowings of the Co-Borrowing Group under the terms of the lending agreement with banks. See Note 2.

        The Company leases certain equipment and facilities under operating leases. Operating lease expense was approximately $126,000 and $124,000 for 2001 and 2000, respectively. Future minimum rental payments under non-cancelable operating leases are as follows:

        The Company is subject to federal, state and local environmental regulations with respect to its operations. The Company believes that it is operating in substantial compliance with applicable environmental regulations. Manufacturing and other operations at the Company's various facilities may result, and may have resulted, in the discharge and release of hazardous substances and waste from time to time. The Company routinely responds to such incidents as deemed appropriate pursuant to applicable federal, state and local environmental regulations.

18

---

10. MAJOR CUSTOMERS

        Sales to the Company's largest customer represented approximately 12% and 8% of total sales for 2001 and 2000, respectively.

11. INCOME TAX EXPENSE

        The Company is a wholly-owned subsidiary of Owosso Corporation and is included in the Parent's consolidated federal tax returns. Income tax expense or benefit is allocated to the Company on a separate return basis. The Company is obligated to make payment to or receive payment from the Parent for tax expense (benefit) determined on this basis.

        The income tax provision consists of the following:

        The components of the Company's net deferred tax assets and liabilities are as follows:

        The Company has recorded a valuation allowance which management has determined is sufficient to reduce its deferred tax assets to an amount which is more likely than not to be realized. The difference between the Company's effective tax rate and the statutory rate is predominantly due to non-deductible expenses.

19

---

12. SUBSEQUENT EVENT

        The Parent is currently engaged in negotiations for the sale of the Company, although no definitive sale agreement is currently in place. It is anticipated that the majority of the proceeds from the sale of the Company will be used to reduce the borrowing of the Co-Borrowing Group. It is further anticipated that, if the events in the preceding sentence occur, the Company will be released from any obligation under the terms of the lending agreement with the banks.

NOTES TO COMBINED FINANCIAL STATEMENTS

(Unaudited)

1. BASIS OF PREPARATION AND PRESENTATION

        The accompanying unaudited combined financial statements as of July 28, 2002 and July 28, 2001 and for the nine-months then ended include the accounts of Motor Products—Owosso Corporation and Motor Products—Ohio Corporation (the Company). On July 30, 2002, the Company was sold to Allied Motion Technologies, Inc. (formerly Hathaway Corporation), a publicly held corporation, for $11,800,000.

        The combined financial statements included herein have been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission and include all adjustments which are, in the opinion of management, necessary for a fair presentation. Certain information and footnote disclosures normally included in financial statements that are prepared in accordance with accounting principles generally accepted in the United States have been condensed or omitted pursuant to such rules and regulations. The Company believes that the disclosures herein are adequate to make the information presented not misleading. The financial data for the interim periods may not necessarily be indicative of results to be expected for the year.

        The preparation of financial statements in accordance with accounting principles generally accepted in the United States requires management to make certain estimates and assumptions. Such estimates and assumptions affect the reported amounts of assets and liabilities as well as disclosure of contingent assets and liabilities at the date of the consolidated financial statements, and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.

        It is suggested that the accompanying condensed interim financial statements be read in conjunction with the Combined Financial Statements and related Notes to such statements as of and for the Fiscal Years Ended October 29, 2001 and October 29, 2000.

2. RELATED PARTY TRANSACTIONS

        As of July 28, 2002, the Company has made net advances to the Parent of $8,325,000. No interest is charged to the Parent on these advances and there is no contractual due date.

        On July 30, 2002, the Company was released from any obligation under the Parent's lending agreement with banks.

b)

Pro Forma Financial Information.

Unaudited Pro Forma Consolidated Financial Statements

        The following unaudited pro forma financial statements give effect to the acquisition of Motor Products Company on July 30, 2002. The purchase price for Motor Products was $11,800,000 plus acquisition costs of $712,000, resulting in a total purchase price of $12,512,000. The Company paid $11,500,000 in cash at closing and $300,000 was paid in January 2003. The Company borrowed $4,000,000 under an amended credit agreement in July 2002 to fund a portion of the purchase price.

        The following presents the Company's unaudited pro forma financial information for the fiscal year ended June 30, 2002, and the six-month periods ended December 31, 2002 and 2001. The

24

---

unaudited pro forma statement of operations for the fiscal year ended June 30, 2002 and for six months ended December 31, 2001 gives effect to the acquisition of Motor Products as if it had occurred on July 1, 2001. The unaudited pro forma statement of operations for the six months ended December 31, 2002 gives effect to the acquisition of Motor Products as if it had occurred on July 1, 2002. An unaudited pro forma balance sheet as of December 31, 2002 has not been included as the acquisition of Motor Products has already been reflected in the December 31, 2002 consolidated balance sheet included in the Company's Transitional Report on Form 10-K filed on March 31, 2003. Because Motor Products fiscal year end was October 28, 2001, for purposes of these pro forma financial statements, Motor Products results of operations were recast to conform to the Company's operating results.

        The unaudited pro forma consolidated financial statements should be read together with the Company's consolidated financial statements as of December 31, 2002, including the notes thereto, included in the Allied Motion Technologies, Inc. Transitional Report on Form 10-K for the fiscal year ended December 31, 2002 as well as the audited and unaudited financial statements of Motor Products which are included in this current report.

        In addition, the unaudited pro forma information should be read in conjunction with the unaudited pro forma financial information and the unaudited historical financial statements of the Power and Process Business, which were included in the Company's previously filed proxy statement dated June 24, 2002. The Power and Process Business was sold on July 29, 2002, and as a result, the Power and Process Business has been presented as a discontinued operation in the Company's consolidated financial statements.

        The pro forma financial information is for informational purposes only and does not purport to present what the Company's results would actually have been had these transactions actually occurred on the dates presented or to project the Company's results of operations or financial position for any future period.

        The acquisition of Motor Products was recorded as a purchase for accounting purposes, and accordingly, the assets acquired and liabilities assumed were recorded at their estimated respective fair market values. The pro forma adjustments do not reflect adjustments for anticipated operating efficiencies which the Company expects to achieve as a result of this acquisition. The allocation of the consideration paid by the Company was based on a review of the fair market values of assets acquired and liabilities assumed at the closing date of the acquisition.

NOTES TO UNAUDITED PRO FORMA CONSOLIDATED FINANCIAL STATEMENTS

Note 1—Basis of Presentation

        The accompanying unaudited pro forma consolidated financial statements reflect the acquisition of 100% of Motor Products—Owosso Corporation and Motor Products—Ohio Corporation (the "acquisition of Motor Products") by Allied Motion Technologies, Inc. (Allied).

        In accordance with SFAS No. 144, the historical consolidated statements of operations have been recast to present the Company's Power and Process Segment as a discontinued operation due to the sale of the Power and Process segment operations in July 2002 and March 2003.

        The accompanying unaudited pro forma consolidated statements of operations for the year ended June 30, 2002 and the six month periods ended December 31, 2002 and 2001 assume that the acquisition of Motor Products occurred at the beginning of such period.

        The purchase price for the acquisition of Motor Products was $11,800,000 which included $7,500,000 in cash paid at closing, $4,000,000 loan from Silicon Valley Bank and $300,000 note payable to the seller. In addition, the Company incurred estimated acquisition costs of $712,000. As such, the total purchase price of Motor Products was $12,512,000.
