                             2004            2,500,000

Operations will be the greater of (a) $1,209,000 or (b) the EBIT from the
Michigan Regional Operations for the fiscal year in which the Earnout is to
be calculated.

For purposes of calculating EBIT, no reduction shall be made for (1)
interest charges on any indebtedness, (2) costs attributable to the

(4) any management fees charged by Purchaser to the Earnout Companies that

a material portion of the assets of the Earnout Companies, whether directly
or indirectly (through a transfer of such assets, a sale of stock, a merger
or otherwise), so as to, in the reasonable judgment of Sellers, have an
adverse effect on their receipt of the Maximum Earnout Payment (a "Change
in Control"), each Seller may, at such Seller's option, either:

(a) continue the Earnout as outlined in Section 1.4(c), or

(b) receive, at the time of a Change in Control, an amount equal to 70% of
the sum of (a) such Seller's pro rata portion of the Maximum Earnout
Payment less (b) all prior Earnout Payments paid by the Purchaser to such
Seller.  

The amount, if any, payable in respect of each of the fiscal years set
forth shall be payable, without interest, as soon as practicable after the
completion of the audit for such fiscal year, but in any event within 120
days following the end of such fiscal year.

Section 1.5 Earnout Procedures.  (a) Purchaser agrees to maintain
accounting records sufficient to allow the computation and verification of
the computation of the payments by the Purchaser to the Sellers under
Section 1.4(c) (each, an "Earnout Payment").

(b) In connection with the making of each Earnout Payment the Purchaser
shall deliver to the Sellers a copy of the audited consolidated financial
statements of Matrix Service Company, together with certain supplemental
income data of the Earnout Companies, a schedule setting forth the
computation of such payment and a copy of any other financial information
used in making such computation.  The Sellers shall have the right
following their receipt of an Earnout Payment to cause an accounting firm
chosen by the Sellers (the "Sellers' Accountants") to conduct an accounting
audit of the Earnout Companies at Sellers' expense (except as provided
below) solely for the purpose of determining the amount of such Earnout
Payment, provided that such audit shall be conducted upon reasonable
advance notice at Matrix Service Company at 10701 East Ute Street, Tulsa,
Oklahoma 74116, during normal business hours and in a manner which does not
unduly interfere with the business operations of the Earnout Companies. 
The Sellers shall give the Purchaser written notice of such an accounting
audit within twenty days following Sellers' receipt of the Earnout Payment
and the accompanying required schedule and financial information (the
"Delivery Date"). The Purchaser's computation of any Earnout Payment shall
be conclusive and binding upon the parties hereto unless, within twenty
days following the Delivery Date or, if Sellers have elected to have an
accounting audit conducted, within ten days of Sellers' receipt of the
report from Sellers' Accountants regarding the Earnout Payment, any Seller
notifies the Purchaser in writing (the "Seller's Notice") that such Seller,
either individually or on behalf of such Seller and the other Sellers
identified in the Seller's Notice (individually or collectively, as the
case may be, the "Notifying Seller"), disagrees with the Purchaser's
computation of the Earnout Payment.  The Seller's Notice shall include a
schedule setting forth the Notifying Seller's computation of the Earnout
Payment, together with a copy of any financial information, other than that
previously supplied by the Purchaser to the Sellers, used in making the
Notifying Seller's computation.  The Notifying Seller shall send a copy of
the Seller's Notice to each Seller who is not a Notifying Seller.

The Notifying Seller's computation of the Earnout Payment under this
Section 1.5(b) shall be conclusive and binding upon the parties hereto
unless, within twenty days following the Purchaser's receipt of the
Seller's Notice, the Purchaser notifies the Sellers in writing that it
disagrees with the Notifying Seller's computation of the Earnout Payment. 
If the Purchaser disagrees with the Notifying Seller's computation of the
Earnout Payment, the Purchaser and the Notifying Seller shall request a
national firm of independent certified public accountants mutually
agreeable to the Purchaser and the Notifying Seller to compute the amount
of the Earnout Payment as promptly as possible, which computation shall be
conclusive and binding upon the Purchaser and the Notifying Seller.  In the
event that the Purchaser and the Notifying Seller cannot agree on such a
national firm of independent certified public accountants, then the names
of the national accounting firms, exclusive of any such firm which is
rendering or has within the past three years rendered services to the
Purchaser or the Notifying Seller or their Affiliates, shall be selected by
lottery until one such firm is willing to compute the disputed payment for
purposes of this Agreement.  The expenses of any computation by any such
national accounting firm selected by the Purchaser and the Notifying Seller
to resolve computational disputes hereunder shall be borne half by the
Purchaser and half by the Notifying Seller.

In the event the amount of Earnout Payment to be paid by the Purchaser to
the Sellers in accordance with Section 1.4(c) is recomputed in accordance
with this Section 1.5, the adjustment to the amount of the Earnout Payment
shall be paid by the Purchaser to the Notifying Sellers within ten business
days after the date of final recomputation of such payment.  If any final
determination of the Earnout Payment shall exceed the Purchaser's original
computation of such Earnout Payment by more than ten percent (10%), then
the Earnout Payment shall also include interest on such difference from the
date upon which the original computation was delivered by the Purchaser to
the Sellers to the date of payment of the Earnout Payment, at a per annum
rate equal to the rate of the Note and the Purchaser shall reimburse the
Notifying Sellers or pay directly for the fees and expenses of Sellers'
accountants.

Sellers who are not Notifying Sellers may become Notifying Sellers by
delivering a written request to be treated as such to the Notifying Seller
and the Purchaser within ten days of receipt of the Seller's Notice given
by the Notifying Seller, whereupon such Seller shall be deemed to have been
a Notifying Seller identified in the Seller's Notice, with all rights and
obligations of a Notifying Seller provided in this Section 1.5.

Each of the Sellers hereby appoints James D. Hammond to serve as the
Notifying Seller on his or her behalf with full power and authority to make
the determinations and to take or refrain from taking the actions within
the authority of the Notifying Seller.  Each Seller shall have the right to
withdraw said appointment upon written notice to the Purchaser and each of
the other Sellers.

Section 1.6 Delivery of Certificates Representing the Shares.  At the
Closing, the Sellers shall deliver to Purchaser stock certificates
representing the Shares, duly endorsed in blank for transfer or accompanied
by appropriate stock powers duly executed in blank with all taxes, direct
or indirect, attributable to the transfer of such Shares paid or provided
for.

Section 1.7 Employment and Non-Competition Agreements.  At the Closing,
James D. Hammond, James W. Buhler, Tor F. Larson, and Douglas P. Leh shall
enter into employment and  non-competition agreements (the "Employment and
Non-Competition Agreements") with Purchaser in the form of Exhibit 1.7

plan is or may become insolvent.  Seller Corp. has paid all premiums (and
interest charges and penalties for late payment, if applicable) due to the

required pursuant to Section 412(m) of the Code with respect to any Plan
have been paid by Seller Corp. on or before the due date for such
contributions.  No accumulated funding deficiency (as defined in Section
302 of ERISA and Section 412 of the Code), whether or not waived, exists

Corp. has made or shall make full and timely payment of or has accrued or
shall accrue all amounts which are required under the terms of the Plans to
be paid as a contribution to each such Plan with respect to the period from
the end of the last plan year ending before the date of this Agreement to
the Closing Date.

(8) All contributions made to or accrued with respect to all Plans are
