                           CHANGE OF CONTROL AGREEMENT



      This Agreement is made this __ day of ___________________, 199__ between (
the "Executive") and Electroglas, Inc., a Delaware corporation (the "Company").

      WHEREAS, the Executive is employed by the Company; and

      WHEREAS, the Company desires to retain the services of Executive in the
event of a change of control (as hereinafter defined) of the Company.

      NOW, THEREFORE, in consideration of the mutual covenants contained herein,
the parties hereto agree as follows:


      1.    Definitions.

            (a)   Change of Control. For purposes of this Agreement only, a
"Change of Control" shall be defined as:

                  (i)   a merger or consolidation in which the Company is not
the surviving entity, except for (1) a transaction in which the principal
purpose is to change the state of the Company's incorporation, or (2) a
transaction in which the Company's stockholders immediately prior to such merger
or consolidation hold (by virtue of securities received in exchange for their
shares in the Company) securities of the surviving entity representing more than
fifty percent (50%) of the total voting power of such entity immediately after
such transaction;

                  (ii)  the sale, transfer or other disposition of all or
substantially all of the assets of the Company, unless the Company's
stockholders immediately prior to such sale, transfer or other disposition hold
(by virtue of securities received in exchange for their shares in the Company)
securities of the purchaser or other transferee representing more than fifty
percent (50%) of the total voting power of such entity immediately after such
transaction; or

                  (iii) any reverse merger in which the Company is the surviving
entity but in which the Company's stockholders immediately prior to such merger
do not hold (by virtue of their shares in the Company held immediately prior to
such transaction) securities of the Company representing more than fifty percent
(50%) of the total voting power of the Company immediately after such
transaction.

            (b)   Cause. For purposes of this Agreement only, the Company shall
have "Cause" to terminate the Executive's employment hereunder only on the basis
of (i) fraud, (ii) misappropriation, (iii) embezzlement or (iv) willful
engagement by the Executive in misconduct, which misconduct is demonstrably and
materially injurious to the Company and its subsidiaries, taken as a whole. No
act, or failure to act, on the part of the Executive shall be considered
"willful" unless done, or omitted to be done, by the Executive without a
reasonable and actual belief that the action or omission was in the best
interests of the Company and its subsidiaries.

            (c)   Good Reason. "Good Reason" shall exist if: (i) there is an
assignment to the Executive of any duties materially inconsistent with or which
constitutes a material change in the Executive's position, duties,
responsibilities or status with the Company, or a material change in the
Executive's reporting responsibilities, titles or offices; or removal of the
Executive from or failure to reelect the Executive to any of such positions,
except in connection with the termination of employment for Cause, or due to
disability, retirement, death or termination of employment by the Executive
other than for Good Reason; (ii) there is a reduction by the Company in the
Executive's annual salary then in effect, other than a reduction similar in
percentage to a reduction generally applicable to similarly situated employees
of the Company; (iii) the Company acts in any way that would adversely affect
the Executive's participation in or materially reduce the Executive's benefits
under any benefit plan of the Company in which the Executive is participating or
deprive the Executive of any material fringe benefit enjoyed by the Executive,
except those changes generally affecting similarly situated employees of the
Company; or (iv) the Company reduces the number of paid vacation days to which
the Executive is then entitled.

            (d)   Closing Date. "Closing Date" shall mean the date of the first
closing of any transactions constituting a Change of Control.

            (e)   Termination Date. "Termination Date" shall mean the date the
Executive's employment is terminated by the Company other than for Cause or is
terminated by the Executive for Good Reason.

            (f)   Company. "Company" shall mean Electroglas, Inc. and its
successors or assigns (including without limitation, any entity, entities or
persons acquiring control of the Company through a Change of Control).

      2.    Continuation of Salary and Benefits; Vesting of Equity Incentives.
If, during the twelve (12) month period following the Closing Date of a Change
of Control, the Company shall terminate the Executive's employment other than

in such event:

            (a)   Continuation of Salary. The Company shall continue to pay the
Executive's base salary in effect as of the Termination Date for a period of
twelve (12) months after the Termination Date. Such salary shall be paid to the
Executive in accordance with the Company's regular payroll practices then

            (b)   Bonus. In addition to the salary continuation set forth in
Section 2(a) above, the Company shall pay the Executive a bonus according to the
following formula:

                  (i)   If the Termination Date occurs after the Executive's
bonus for the last completed fiscal year has been determined by the Compensation
Committee of the Board of Directors (the "Compensation Committee") and paid to
the Executive, then the Executive shall receive a bonus in the amount of no less
than:

                         X1 + X1(Y/365)

                  (ii)  If the Termination Date occurs before the Executive's
bonus for the last completed fiscal year has been determined by the Compensation
Committee and paid to the Executive, then the Executive shall receive a bonus in
the amount of no less than:

                        2(X2) + X2(Y/365)

                  where:

                        "X1" = the bonus amount paid to the Executive for the
                        last completed fiscal year;

                        "X2" = the bonus amount paid to the Executive for the
                        fiscal year prior to the last completed fiscal year; and

                        "Y" = the number of days in the current fiscal year
                        prior to and including the Termination date.

            The bonus shall be paid in equal monthly payments over a period of
twelve (12) months after the Termination Date. Such amount shall be payable to
the Executive regardless of the Company's financial performance, and shall not
be conditioned on the Company's continued satisfaction of any goals or criteria
required by any compensation plan;

            (c)   Medical and Dental Benefits. For the period that salary
continuation payments are being made, the Company shall either: (i) continue the
Executive's medical and dental benefits as such benefits are generally offered
to the Company's employees as of the Termination Date, or (ii) reimburse the
Executive for COBRA payments made by the Executive to maintain his medical and
dental benefits, as applicable under the Company's insurance policies;

but unused vacation time as of the Termination Date;

            (f)   Stock Options, Performances Shares or Units and Restricted

share or unit shall vest in its entirety and become exercisable or, with respect
to such performance share or unit or restricted share or unit, be released from
restrictions on transfer and repurchase rights, immediately prior to the
Termination Date; provided that, at least one (1) year has elapsed between the
date of this Agreement and the Termination Date; and

            (g)   Extension of Stock Option Exercise Term. All vested stock
options held by the Executive as of the Termination Date shall expire six (6)
months after the Termination Date.

      3.    No Employment Agreement, Employment at Will. Executive and the
Company each acknowledge and agree that: (i) this Agreement does not provide for
the terms and conditions of Executive's employment with the Company prior to any
Change of Control and does not require or obligate Executive to provide services
to the Company or the Company to continue to employ Executive; and (ii)
Executive's employment with the Company is and remains an employment
relationship terminable at will and without advance notice by either Executive
or the Company.

      4.    Release of the Company and Its Affiliates. Upon a termination of
Executive's employment with the Company following a Change of Control for which

and subject to full performance by the Company of its obligations hereunder,
Executive hereby forever and completely releases and discharges the following
