                                                                  Execution Copy
                             CONSULTING AGREEMENT


                               Eugene E. Prince


THIS CONSULTING AGREEMENT, dated and effective as of September 1, 1998, is
between Hathaway Corporation, a Colorado corporation ("Company"), and Eugene E.
Prince ("Consultant").

                                   RECITALS

Consultant has served for many years as the Chief Executive Officer of the
Company and is now retiring.  He has acknowledged skills and experience in the
business conducted by the Company, and the Company desires to obtain the
continuing benefit of Consultant's knowledge, skills and experience and assure
itself of the ongoing right to Consultant's services from and after the date
hereof, and is willing to do so on the terms and conditions set forth in this
Agreement.  Consultant is willing and able to continue to render services to the
Company, from and after the date hereof, on the terms and conditions set forth
in this Agreement.


                                 AGREEMENT

NOW THEREFORE, the Company and Consultant agree as follows:

     1.   Consultant Relationship.  The Company hereby retains Consultant to
provide consulting services to the Company primarily on matters involving the
Company's motion control products, but also on other matters as requested by the
President and CEO.  Consultant shall report to the President and CEO as
requested.  Consultant shall devote such time to the Company's business as is
reasonably necessary to carry out assigned responsibilities, but it is not
expected that Consultant will be required to give more than 60 hours per month
of service under this Agreement.  It is expected that Consultant will devote
about 40 hours per month on motion control products and about 20 hours per month
on other matters.  Consultant will serve as a director of subsidiary entities of
the Company as requested.  Consultant will do such traveling as reasonably may
be required in connection with the performance of consulting duties and
responsibilities.  Consultant is an independent contractor.

     2.   Term.  The term of this Agreement shall commence on September 1, 1998,
and continue until terminated by either party upon 30 days written notice.

     3.   Service on Company Board.  So long as Consultant owns at least 10% of
the issued shares of the Company, the board of directors of the Company shall
nominate Consultant for election to the board of directors.  If Consultant is
elected to the board of directors of the Company, the board of directors will
request that Consultant be nominated for the position of chairman of the board
of directors, but failure to elect Consultant as chairman of the board of
directors for any reason shall not constitute resignation from the board or
termination of Consultant's services under this Agreement.

     4.   Compensation.  Consultant will be compensated at the standard rate
paid by the Company to directors for consulting services, which at the time of
this Agreement is $250 per hour.  If the rate paid to directors for consultation
services should be increased during the term of this Agreement, the rate paid to
Consultant shall be likewise increased.  As a member of the board of directors,
Consultant will be paid the standard compensation for nonemployee directors for
attending board or committee meetings and other services as a director.
Consultant is not eligible for benefits and perquisites provided by the Company
to its employees but is eligible for benefits and perquisites provided by the
Company to its directors.  Consultant will be paid at the rate of $250 per hour
for travel time.

     5.   Existing Agreements.  This Agreement constitutes a retirement
arrangement as contemplated by Section 4.2 of Consultant's Employment Agreement
with the Company, dated as of July 1, 1993 (the "Employment Agreement").
Effective August 13, 1998, Consultant resigned as President and Chief Executive
Officer of the Company and continued as an employee through August 31, 1998.
The Employment Agreement is terminated effective August 31, 1998, except for
benefits thereunder which, by its terms, were intended to survive termination.
Consultant is also a party to a letter agreement dated June 15, 1989 ("Severance
Agreement") between the Company and Consultant providing certain benefits to
Consultant upon a change in control of the Company.  Effective August 31, 1998,
the Severance Agreement is terminated except for benefits which, by its terms,
were intended to survive termination.

     6.   Expenses. The Company promptly shall reimburse Consultant, upon
presentation of appropriate receipts and vouchers, for any reasonable business
expenses incurred by Consultant in connection with the performance of his duties
and responsibilities thereunder.

     7.   Stock Options.   No unexercised stock options shall be terminated by
reason of the termination of Consultant's Employment Agreement pursuant to
Section 5 hereof, and all unexercised stock options shall continue to be
exercisable by Consultant as a director of the Company.

     8.   Confidential Information.

          8.1    Disclosure and Use.  Consultant shall not disclose, either
     during or subsequent to Consultant's consulting relationship with the
     Company, any confidential information or proprietary data of the Company,
     whether or not developed by Consultant, except (i) as may be required for
     Consultant to perform Consultant's duties with the Company; (ii) to the
     extent such information has been disclosed to Consultant by a third party
     who is not subject to restriction on the dissemination of such information;
     (iii) as such information becomes generally available to the public other
     than as a result of a disclosure by Consultant; (iv) to the extent such
     information is independently developed by Consultant; (v) information which
     must be disclosed as a result of a subpoena or other legal process, or (vi)
     if Consultant shall first secure the Company's prior written authorization.
     This covenant shall survive the termination of Consultant's consulting
     relationship with the Company, and shall remain in effect and be
     enforceable against Consultant for so long as any such Company confidential
     information or proprietary data retains economic value, whether actual or
     potential, from not being generally known to other persons who can obtain
     economic value from its disclosure or use.

          8.2    Return of Materials.  Upon termination of this consultant
     relationship, Consultant shall promptly deliver to the Company all customer
     lists, specifications, drawings, listings, documentation, manuals, letters,
     notes, note books, reports, and copies thereof, and all other materials of
     a secret or confidential nature relating to the Company's business, which
     are in the possession or under the control of Consultant.

     9.   Inventions and Discoveries.  Consultant hereby assigns to the Company
all of Consultant's rights, title and interest in and to all inventions,
discoveries, processes, designs and other intellectual property which relates to
any business of the Company which, at the time of the invention, discovery or
design, is a source of substantial revenue for the Company (hereinafter referred
to collectively as the "Inventions"), and all improvements on existing
Inventions made or discovered by Consultant during the term of Consultant's
relationship with the Company.  Promptly upon the development or making of any
such Invention or improvement thereon, Consultant shall disclose the same to the
Company and shall execute and deliver to the Company such reasonable documents
as the Company may request to confirm the assignment of Consultant's rights
therein and, if requested by the Company, shall assist the Company in applying
for and prosecuting any patents which may be available in respect thereof.  This
Section 9 does not apply to any Invention other than one which relates to any
business of the Company which, at the time of invention, is a source of
substantial revenue for the Company, regardless of when, where or how developed.
