<PAGE>

         1.  RESIGNATION.  It is agreed and understood that Andrade will
             -----------
tender his written resignation to the Company effective August 31, 2001. The
form of Andrade's resignation is attached hereto and made a part hereof as
Exhibit A.

         2.  DUTIES PENDING RESIGNATION. It is agreed and understood that
             --------------------------
between the date of this Agreement and November 15, 2001, Andrade shall continue
his employment with the Company as an employee but not as President or Chief
Operating Officer. Even though Andrade will continue his employment until
November 15, 2001, it is agreed that his responsibilities and duties will
significantly change from the duties that Andrade provided in the past. It is
agreed and understood that Andrade shall continue to provide such duties as may
be reasonably required by the Company to provide for a smooth transition between
the date of this Agreement and November 15, 2001. It is further agreed and
understood that Andrade shall provide such services as may be reasonably agreed
upon by Andrade and the CEO of the Company including, but not limited to,
working with banks that provide credit facilities to the Company; working with
the indenture holders; working with major customers of the Company; working with
dealers, and working with the Company employees all with a view to providing a
smooth transition after Andrade resigns as an employee of the Company on
November 15, 2001. These services shall be provided by Andrade at the reasonable
request of the CEO; however, it is further agreed and understood that all such
duties shall be with reasonable prior arrangements and notification between the
CEO and Andrade. It is specifically agreed and understood that the Company shall
not require Andrade to be at the Company's offices on a full-time basis and, in
fact, it is contemplated that Andrade will be absent from the Company's offices
for substantial periods in September and October.

                                       2

<PAGE>

         It is further agreed and understood that Andrade shall be entitled to
continue to receive his compensation and all benefits which were heretofore
provided by practice and/or pursuant to Andrade's employment agreement between
the date this Agreement is executed and November 15, 2001. It is further agreed
that the Company will reimburse Andrade for any and all reasonable business
expense incurred on or before November 15, 2001, even though the bills are
actually received by the Company on or after November 15, 2001.

         3.  RESIGNATION AND PAYMENTS. As of November 15, 2001, Andrade shall no
             ------------------------
longer be entitled to the compensation and benefits he previously received as an
employee and which are more particularly defined in his employment agreement
dated August 30, 2000. As of November 15, 2001, Andrade shall only be entitled
to the consideration which is specially set forth in this Agreement.

         Effective November 15, 2001, Andrade shall be entitled to severance
payments for eighteen (18) months which shall be computed at Andrade's current
salary of Three Hundred Ten Thousand Dollars ($310,000.00) per annum which will
be payable in equal twice-monthly installments commencing on November 30, 2001,
i.e. the sum of $25,833.33 per month or $12,916.66 per pay period on the 15th
and last day of each month. The Company shall issue Andrade an IRS form 1099
each year.

         Andrade shall not be required to mitigate the amount of any payment
provided for in this Agreement in connection with or following termination of
his employment by seeking other employment or otherwise, nor shall the amount of
any payments provided for herein be reduced by any compensation earned by
Andrade as the result of any future employment or services as a director,
consultant or otherwise.

         4.  PERSONAL PROPERTY LOCATED WITHIN ANDRADE'S OFFICE. It is agreed and
             -------------------------------------------------
understood that Andrade shall be entitled without any cost to him to remove any
and all items of personal property currently located within his office at the
time Andrade vacates his offices, i.e., on or before November 15, 2001. It is
agreed and understood that Andrade shall be entitled to take all such items of
personal property regardless of whether those items of personal property were
purchased by the Company or by Andrade. In other words, it is agreed and
understood that at the time Andrade vacates his offices he shall be entitled to
take any and all desks, chairs, bookcases, files, other furniture, pictures,
books, and computer(s) and any other items of personal property. The only
exception to the foregoing is that it is agreed and understood that Andrade
shall not be allowed to take any personal property that would be considered
confidential and/or proprietary in nature by the Company, i.e., certain computer
programs, data, etc. In addition, Andrade shall be entitled to retain the cell
phone equipment and accessories which he is currently using without cost to him.

         5.  PRIOR EMPLOYMENT AGREEMENT. As of November 15, 2001, it is agreed
             --------------------------
and understood that the employment agreement heretofore entered into between the
parties and dated as of August 30, 2000, shall be effectively cancelled and
shall have no further force or effect, i.e., Andrade shall not be entitled to
any further salary or benefits from the Company except as expressly set forth
herein.

         6.  COVENANT NOT TO COMPETE. As previously stated, the parties hereto
             -----------------------
are entering into a Stock Purchase Agreement at the same time this Agreement is
being executed. The obligations of the parties in this Agreement are in no way
contingent upon any of the terms and conditions of said Stock Purchase
Agreement. However, if the all of the terms and provisions of the Stock Purchase
Agreement are fully effectuated, it is agreed and understood that Andrade shall
not

                                       4

<PAGE>

be employed by or otherwise engage in or be interested in any business in
competition with the Company for a period of eighteen (18) months commencing
November 15, 2001; provided, however, that Andrade's ownership of stock in any
such business shall not be considered a violation of this paragraph if the stock
of such business is traded on a national securities exchange or NASDAQ and
Andrade owns less than one (1) percent of the equity thereof; and provided
further, that the foregoing shall not limit or prevent Andrade from (i) serving
on the board of directors of any corporation on which Andrade is now serving, or
(ii) investing in any business in which Andrade currently has an investment. For
purposes of this Agreement a business that is "in competition" with the Company
shall mean an entity that is engaged in the same or similar business as the
Company and derives at least fifty percent (50%) of its revenue from the
manufacture of grain storage systems, poultry feeding equipment and/or swine
producing equipment.

         7.  CONFIDENTIALITY. Andrade agrees he will not divulge or appropriate
             ---------------
for his own use or for the use of a business in competition with the Company,
any secret or confidential information or knowledge pertaining to the business
of the Company, or of any of its subsidiaries, obtained by Andrade in any way
while he was employed by the Company. Further, the Company agrees it will not
divulge or release any confidential, secret, or personal information regarding
Andrade.

         8.  PERSONAL GUARANTEES. The Company believes that Andrade has not
             -------------------
personally guaranteed any of the obligations of GSI, however, GSI will review
its records to attempt to identify any such personal undertakings by Andrade.
The Company agrees it shall request in writing to any person or entity to whom
Andrade may have provided a personal guarantee that Andrade be released from
such guarantee. It is agreed that other than the Company making this

                                       5

<PAGE>

request in writing it shall not be obligated to take any other action, however,
it is also agreed and understood that to the extent Andrade is required to
satisfy any such obligation that Andrade may obtain reimbursement from the
Company regarding any such personal guarantee.

         9.    MUTUAL RELEASES.
               ---------------

period of three (3) years from November 15, 2001, without the prior written
