Dear Jim:

    On behalf of the Board of Directors of Mechanical Technology Incorporated,
I am pleased to offer you the position of Vice President and General Manager of
Ling Electronics, Inc., effective March 24, 1997.

    As such, you will be responsible for all aspects of the operations and
performance of Ling.  You will report to the President and Chief Operating
Officer of MTI and will work closely with the Chief Executive Officer and the
Board of Directors to develop and implement strategies and goals designed to
return the Ling to profitability and to position it for future growth and
profitability.

    We have agreed to employ you for three years at a base annual salary of
$115,000. From time to time, but not less than annually, your performance will
be reviewed and you may be eligible for salary adjustments at the discretion of
the Compensation Committee of MTI's Board of Directors.  

    You will also be eligible for cash incentive compensation as follows:

              3% of Annual Pretax Income up to $1,000,000
              2% of Annual Pretax Income in excess of $1,000,000

    You will be awarded options to purchase 15,000 shares of MTI common stock at
a price to be set on the day you sign this agreement.  Vesting in these options
will occur as follows:

              Year 1  5,000 options if Pre Tax Income exceeds $1,000,000
              Year 2  5,000 options if Pre Tax Income exceeds $1,400,000
              Year 3  5,000 options if Pre Tax Income exceeds $1,700,000

    Pre Tax Income will be defined as income prior to corporate assessments and
taxes.  Cash incentive compensation and vesting in options will be subject to
the review of operating results by the Company's independent auditors. Normally,
we expect such payments and vesting to occur in December or January following
the close of the fiscal year on September 30.
	
    You will be eligible for three weeks paid vacation annually and to
participate in the standard employee benefit packages offered to individuals in
comparable positions in the Company.  An employee handbook explaining these
benefits will be provided under separate cover.
	
    MTI will advance to you the sum of $30,000 in conformance with the enclosed
agreement and promissory note.  Of this amount, $10,000 will be advanced upon
execution of this letter; $10,000 will be advanced on the effective date of your
employment (anticipated to be March 24, 1997); and the balance will be advanced
within 30 days of the effective date of employment.  This advance is to cover
your cash flow needs during the transition period of your relocation, including
but not limited to temporary living expenses (housing, food and travel) for the
first three months of your employment, security deposits on housing rental, etc.
Reimbursement for normal business expenses will be in accordance with Company
policy.  Should you buy a home during the first 18 months of employment,
refunded security deposits may be applied to closing costs associated therewith.
	
    You will be eligible for reimbursement of ordinary relocation costs
associated with your move to the Anaheim area, including: two visits by you and
your spouse to explore living arrangements; personal transportation and expenses
for you and your spouse during relocation; packing, transportation, and
insurance associated with moving household goods; temporary living arrangements
pending the availability of housing; and reasonable closing costs associated
with the purchase of a primary residence.  Reimbursement for the costs of moving
your personal, household possessions will be "grossed up" to reflect the tax
consequences of such reimbursement.

    If MTI decides to sell or discontinue the operations of Ling during the
period of this agreement, and if a buyer of Ling does not continue your
employment, you will be paid severance allowance equivalent to one year's base
salary.  If you leave employment on your own initiative within one year, the
relocation costs cited above will be reimbursed to the Company.

    NOW THEREFORE, the parties hereto agree as follows:

    1.  MTI will pay bonuses to Employee on March 24, 1998, March 24, 1999, and

to the Employee, and subject to standard payroll withholdings.

    2.  In the event that Employee ceases to be employed by MTI for any reason
whatsoever prior to any of the dates set forth in Paragraph 1 above, then
