Dear
Mr. Warzala:

Allied
Motion Technologies Inc. f/k/a Hathaway Corporation (the "Company") entered into an agreement with you dated May 1, 2002 (the "Agreement"), under which the Company
agreed to provide you with certain severance benefits in the event your employment with the Company is Terminated
following a change in control of the Company. In order to comply with the requirements of Section 409A of the Internal Revenue Code, as amended (the "Code"), as well as to incorporate certain
changes to the Agreement approved by the board of directors of the Company (the "Board"), the Company and you hereby agree to amend and restate the Agreement as follows:

The
Company has determined that it is essential to the best interests of the Company and its shareholders to foster the continuous employment of key management personnel including you as
COO of the Company. The Board recognizes that, as is the case with many publicly held corporations, the possibility of a change in control of the Company exists. Such possibility and the uncertainty
and questions which it may raise among management, may result in the departure or distraction of management personnel to the detriment of the Company and its shareholders. In addition, the Company
seeks your unequivocal support in realizing the maximum value per share to shareholders in the event of a disposition of the Company. In the event of a change of control, we also seek your cooperation
in a smooth transition of management. These objectives require employment arrangements that provide security to you in the face of uncertainty.

The
Board has determined that appropriate steps should be taken to reinforce and encourage the continued attention and dedication of members of management, including yourself, to their
assigned duties without distraction in the face of potentially disturbing circumstances arising from the possibility of a change in control of the Company.

In
order to induce you to remain in the employ of the Company, and in consideration of your agreements set forth in Section 2(ii), the Company agrees that you shall receive the
severance benefits set forth in this Agreement in the event your employment with the Company is Terminated subsequent to a change in control of the Company (as defined in Section 2 hereof)
under the circumstances described below.

1.Term of Agreement.As originally drafted, this Agreement commenced on May 1, 2002, and continued in
effect through December 31, 2002. Commencing on January 1, 2003 and each January 1 thereafter, the term of this Agreement automatically extended for one additional year (meaning
that as of each January 1 this Agreement shall then have a term of two years which shall reduce during the ensuing 12 months but shall again be extended on the next following
January 1 to a term of two years) and shall continue to do so unless, not later than the September 30 immediately preceding each such January 1, the Company shall have given
notice that it does not wish to extend this Agreement; provided further, if a change in control of the Company shall have occurred during the original or extended term of this Agreement, this
Agreement shall continue in effect for a period of 24 months beyond the month in which such event occurred.

2.     (i)Change in Control of the Company.    No benefits shall be payable hereunder unless there shall have been a
change in control of the Company, as set forth below. For purposes of this Agreement, a "change in control of the Company" shall be deemed to have occurred (A) if any "Person" (as such term is
used in Sections 13(d) and 14(d) of the Securities Exchange Act of 1934, as

amended
(the "Exchange Act"), other than (1) a trustee or other fiduciary holding securities under an employee benefit plan of the Company, or any Person or entity organized, appointed or
established by the Company for or pursuant to the terms of any such plan, or (2) any Person who, on the date hereof, is a director or officer of the Company or whose shares of common stock of
the Company are treated as beneficially owned (as defined in Rule 13d-3 under the Exchange Act) by any such director or officer, is or becomes the beneficial owner, directly or
indirectly, of securities of the Company representing more than 45% of the combined voting power of the Company's then outstanding securities; or (B) upon the first purchase of outstanding
shares of the Company's outstanding common stock pursuant to a tender or exchange offer (other than a tender or exchange offer made by the Company, by an employee benefit plan established or
maintained by the Company or by any of their respective affiliates); or (C) if during any period of two consecutive years, individuals who, at the beginning of such period, constitute the Board
and any new director (other than a director designated by a person who has entered into an agreement with the Company to effect a transaction described in clauses (A) or (D) of this
Subsection) whose election by the Board or nomination for election by the Company's shareholders was approved by a vote of at least two-thirds (2/3) of the Company directors
then still in office who either (1) were directors at the beginning of the period or (2) whose election or nomination for election was previously so approved, cease for any reason to
constitute a majority thereof; or (D) if the shareholders of the Company approve a merger or consolidation of the Company with any other corporation, other than a merger or consolidation which
would result in the voting securities of the Company outstanding immediately prior thereto continuing to represent (either by remaining outstanding or by being converted into voting securities of the
surviving entity) at least 80% of the combined voting power of the voting securities of the Company or such surviving entity outstanding immediately after such merger or consolidation; or
(E) the shareholders of the Company approve a plan of complete liquidation of the Company or an agreement for the sale or disposition by the Company of all or substantially all of the Company's
assets;

provided, however, a spinoff distribution to shareholders of the Company of all or part of the Company's equity interest in a subsidiary
entity shall not constitute a change in control of the Company.

(ii)Potential Change in Control of the Company.For purposes of this Agreement, a "potential change in control
of the Company" shall be deemed to have occurred if (A) the Company enters into an agreement, the consummation of which would result in the occurrence of a change in control of the Company;
(B) any Person (including the Company) publicly announces an intention to take or to consider taking actions which if consummated would constitute a change in control of the Company;
(C) any Person, other than (1) a trustee or other fiduciary holding securities under an employee benefit plan of the Company, or (2) any Person or entity organized, appointed or
established by the Company for or pursuant to the terms of any such plan, or (3) any Person who, on the date hereof, is a director or officer of the Company or whose shares of common stock of
the Company are treated as beneficially owned by any such director or officer, increases his beneficial ownership of such securities by 8% or more of the shares of the Company issued and outstanding
on the date of such determination; or (D) the Board adopts a resolution to the effect that, for purposes of this Agreement, a potential change in control of the Company has occurred. You agree
that, subject to the terms and conditions of this Agreement, in the event of a potential change in control of the Company, you will remain in the employ of the Company until the earliest of
(1) a date which is twelve (12) months after the occurrence of such potential change in control of the Company, (2) the Termination by you of your employment by reason of death or
Disability or Retirement, as defined in Section 3(i), or (3) the occurrence of a change in control of the Company.

Agreement upon your Termination of employment shall not be made until at least six months following your separation from service. At that time, all amounts, if any, that would have been paid during
