        VOTING AGREEMENT (this "Agreement"), dated as of February 10, 2004, by and between Allied Motion Technologies, Inc., a Colorado corporation ("Parent"), and The John F. Northway, Sr. Trust ("Shareholder").

        WHEREAS, concurrently herewith, Parent, AMOT, Inc., a Pennsylvania corporation and wholly owned subsidiary of Parent ("Merger Sub") and Owosso Corporation, a Pennsylvania corporation (the "Company"), are entering into an Agreement and Plan of Merger of even date herewith (the "Merger Agreement"), pursuant to which each share of Company Common Stock and Company Preferred Stock will cease to be existing and outstanding and shall be automatically converted into the right to receive the Common Merger Consideration or the Preferred Merger Consideration, as applicable, and the Merger Sub will be merged with the Company, with the Merger Sub being the surviving entity. Capitalized terms used but not defined herein shall have the meanings set forth in the Merger Agreement.

        WHEREAS, as of the date hereof, Shareholder owns 687,949 shares of Company Common Stock (the "Shares") (for purposes of this Agreement the "Shares" shall also include any shares of the Company acquired by Shareholder after the date of this Agreement but prior to the Effective Time, whether upon the exercise of options, conversion of convertible securities or otherwise); and

        WHEREAS, as a condition to their willingness to enter into the Merger Agreement, Parent and the Merger Sub have required that Shareholder agree, and Shareholder hereby agrees, to take the actions set forth herein;

        WHEREAS, the Shareholder has agreed to enter into this Agreement strictly in his capacity as owner of the Shares and not in any other capacity, including, without limitation, as a director or officer of the Company.

        NOW, THEREFORE, to induce Parent and Merger Sub to enter into the Merger Agreement, and in consideration of the premises and for other good and valuable consideration given to each party hereto, the receipt of which is hereby acknowledged, the parties agree as follows:

        1.      Agreement to Vote.

        1.1    Voting. Shareholder hereby agrees that during the period commencing on the date hereof and continuing until this Agreement terminates pursuant to Section 2 hereof, at any meeting of the Shareholders, however called, Shareholder shall: (a) vote the Shares in favor of the Merger; (b) vote the Shares against any action or agreement that would result in a breach of any covenant, representation or warranty or any other obligation or agreement of the Company under the Merger Agreement; and (c) vote the Shares against any action or agreement (other than the Merger Agreement or the transactions contemplated thereby) that would impede, interfere with, delay, postpone or attempt to discourage the Merger, including, but not limited to: (i) any extraordinary corporate transaction, such as a merger, consolidation or other business combination involving the Company or any of its subsidiaries; (ii) a sale or transfer of a material amount of assets of the Company or any of its subsidiaries or a reorganization, recapitalization or liquidation of the Company and its subsidiaries; (iii) any change in the management or board of directors of the Company, except as otherwise agreed to in writing by the Parent and the Merger Sub; (iv) any material change in the present capitalization or dividend policy of the Company; or (v) any other material change in the Company's corporate structure or business or (vi) any other action which is intended, or could be reasonably expected, to impede, interfere with, delay, postpone or adversely effect the merger and the transactions contemplated by this Agreement and the Merger Agreement. In the event that any corporate action consistent with this Agreement is taken by the shareholders of the company by written consent (including any action to approve the Merger Agreement and the transactions contemplated

thereby), each Shareholder hereby waives any right to receive notice of the taking of such corporate action without a meeting pursuant to Section 1766 of the PBCL or otherwise.

        1.2    Grant of Irrevocable Proxy; Appointment of Proxy.

        (i)    During the period commencing on the date hereof and continuing until this Agreement terminates pursuant to Section 2 hereof, Shareholder hereby irrevocably grants to, and appoints, Richard Smith and Richard Warzala, or either of them, in their respective capacities as officers of Parent, and any individual who shall hereafter succeed to any such office of Parent, and each of them individually, Shareholder's proxy and attorney-in-fact (with full power of substitution), for and in the name, place and stead of Shareholder, to vote (or cause to be voted) the Shares at any meeting of the Shareholders, however called: (a) in favor of the Merger; (b) against any action or agreement that would result in a breach of any covenant, representation or warranty or any other obligation or agreement of the Company under the Merger Agreement; and (c) against any action or agreement (other than the Merger Agreement or the transactions contemplated thereby) that would impede, interfere with, delay, postpone or attempt to discourage the Merger, including, but not limited to: (i) any extraordinary corporate transaction, such as a merger, consolidation or other business combination involving the Company or any of its subsidiaries; (ii) a sale or transfer of a material amount of assets of the Company or any of its subsidiaries or a reorganization, recapitalization or liquidation of the Company and its subsidiaries; (iii) any change in the management or board of directors of the Company, except as otherwise agreed to in writing by the Parent and the Merger Sub; (iv) any material change in the present capitalization or dividend policy of the Company; or (v) any other material change in the Company's corporate structure or business or (vi) any other action which is intended, or could be reasonably expected, to impede, interfere with, delay, postpone or adversely effect the merger and the transactions contemplated by this Agreement and the Merger Agreement.

        (ii)   Shareholder represents that any proxies heretofore given in respect of the Shares are not irrevocable, and that any such proxies are hereby revoked.

        (iii)  Shareholder hereby affirms that the proxy set forth in this Section 1.2 is coupled with an interest and is irrevocable until such time as this Agreement terminates in accordance with its terms. Shareholder understands and acknowledges that Parent is entering into the Merger Agreement in reliance upon Shareholder's execution and delivery of this Agreement. Shareholder hereby affirms that the irrevocable proxy set forth in this Section 1.2 is given in connection with the execution of the Merger Agreement, and that such irrevocable proxy is given to secure the performance of the duties of Shareholder under this Agreement. Shareholder hereby further affirms that the irrevocable proxy is coupled with an interest and may under no circumstances be revoked. Shareholder hereby ratifies and confirms all that such irrevocable proxy may lawfully do or cause to be done by virtue hereof. Such irrevocable proxy is executed and intended to be irrevocable.

        (iv)  The vote of the proxyholder shall control in any conflict between the vote by the proxyholder of such Shareholder's Shares and a vote by such Shareholder of such Shareholder's Shares.

        1.3    No Inconsistent Arrangements. Shareholder hereby covenants and agrees that, except as contemplated by this Agreement and the Merger Agreement, he shall not: (i) except to Parent or the Merger Sub, transfer (which term shall include, without limitation, any sale, gift, pledge or other disposition), or consent to any transfer of, any or all of the Shares or any interest therein; (ii) enter into any contract, option or other agreement or understanding with respect to any transfer of any or all of the Shares or any interest therein; (iii) grant any proxy, power-of-attorney or other authorization, other than pursuant to Section 1.2 of this Agreement, in or with respect to the Shares; (iv) deposit any Shares into a voting trust or enter into a voting agreement or arrangement with respect to the Shares; or (v) take any other action that would in any way restrict, limit or interfere with the performance of his obligations hereunder or the transactions contemplated hereby or by the Merger Agreement or which would make any representation or warranty of Shareholder hereunder untrue or incorrect.
