ALLIED MOTION REPORTS PROFITS FOR THE
QUARTER AND YEAR ENDED DECEMBER 31, 2003

        DENVER, COLORADO—Allied Motion Technologies, Inc. (NASDAQ: AMOT) (formerly Hathaway Corporation) today announced it achieved income from continuing operations for the fourth quarter of $392,000 or $.07 per diluted share compared to $97,000 or $.02 per diluted share for the same period last year. Revenue for the quarter ended December 31, 2003 was $10,684,000 compared to $9,171,000 last year.

        For the year ended December 31, 2003, the Company recognized income from continuing operations of $948,000 or $.19 per diluted share compared to a loss from continuing operations of $59,000 or $.01 per diluted share for the year ended December 31, 2002. Included in the current year's continuing operating results are a pre-tax restructuring charge of $211,000 and a tax benefit of $298,000 related to the realization of a prior year state income tax refund. Revenue for the year ended December 31, 2003 was $39,434,000 compared to $25,046,000 last year. This year's revenue includes revenue from Motor Products Corporation for the full year whereas last year's revenue included only five months. Backlog at December 31, 2003 was $13,383,000.

        The results from discontinued operations for the fourth quarter of this year were zero compared to income of $40,000 for the same period last year. Results from discontinued operations were zero for the year ended December 31, 2003 compared to net income of $284,000 for the year ended December 31, 2002.

        Net income for the fourth quarter was $392,000 or $.07 per diluted share compared to net income of $137,000 or $.03 per diluted share for the fourth quarter last year. Net income for the year ended December 31, 2003 was $948,000 or $.19 per diluted share compared to a net income of $225,000 or $.05 per diluted share for the year ended December 31, 2002.

        "We are very pleased with the results for 2003," commented Dick Smith, CEO of Allied Motion. "During 2003, we achieved the profit goals we set for the year and we also further strengthen our organization which will enhance our ability to successfully grow the Company in the future. We've made significant improvements to our operating efficiencies and are committed to our programs of continuous improvement. While we are pleased with our progress, we will continue to concentrate on building the foundation that will be necessary for us to achieve our long-term goals for growth in sales and profitability. Concurrently, we continue to actively pursue new acquisition opportunities to further our expansion into the motion control industry, as evidenced by our recent announcement regarding the acquisition of Owosso Corporation and its wholly-owned subsidiary, Stature Electric."

        Dick Warzala, President of Allied Motion, added, "During 2003, we exhibited a stable level of sales and maintained our emphasis on internal cost reductions to improve our bottom line. The focused efforts of our dedicated team of employees resulted in an increase of approximately $1 million in revenues and $1.2 million in operating profits in 2003 as compared to 2002 on a proforma basis with Motor Products included for the full year. While we are substantially complete with the restructuring from seven separate operations to three facilities, part of the savings realized was redeployed to add to and enhance the critical engineering resources in our organization. The addition of critical engineering resources is fundamental to the ultimate success of our defined strategy and we are confident this will accelerate our top line growth in the future. In addition, the continued implementation of our lean manufacturing initiatives and an increased emphasis on reducing product costs through strategic sourcing and product re-design efforts will improve our cost effectiveness and further enhance our ability to win new business opportunities in the future."

        Headquartered in Denver, Colorado, Allied Motion designs, manufactures and sells motion control products into applications that serve many industry sectors. Allied Motion is a leading supplier of precision and specialty motion control components and systems to a broad spectrum of customers throughout the world.

The Company's ability to compete in this market depends upon its capacity to anticipate the need for new products, and to continue to design and market those products to meet customers' needs in a competitive world. Actual results, events and performance may differ materially. Readers are cautioned not to place undue reliance on these forward-looking statements as a prediction of actual results.
