           1.1  Matrix Parties Covenant Not to Compete; Right of First Refusal.
Brown, Matrix and GSAC each hereby covenants and agrees with Caldwell and
Caldwell Tanks that for a period of five (5) years following the date hereof,
Brown, Matrix and GSAC shall not, and shall not cause or permit any of their

or (b) engage in any manner in the business of designing equipment, facilities
or methodologies for, procuring or selling equipment or facilities for,
contracting equipment or facilities for, providing project management regarding
equipment or facilities for, or otherwise consulting or providing other services
in connection with, cooling the air for combustion turbines used in any
industry; in either case anywhere within the "Territory" (as defined in Section
74.), whether for its own account or for the account of any other Person;
provided, that the foregoing covenants and agreements of Brown, Matrix and GSAC
shall not


prohibit them (or any of their Affiliates) from engaging in any of the following
activities at any time within the Territory: (i) providing goods and services to
customers pursuant to any warranty, guaranty or other similar obligations under
contracts or agreements that are Retained Obligations as of the date hereof; or
(ii) serving in the capacity as a general contractor (or its equivalent) in
connection with the design, repair, construction, installation, retrofit or
refurbishment of any cogeneration power production facilities (or any portions
thereof) that include or involve equipment or processes for cooling the air for
combustion turbines used in such facilities. In the event Brown, Matrix, GSAC or
any of their Affiliates serve in the capacity as a general contractor (or its
equivalent) as contemplated in (ii) above, and in the event its duties or
authority include the performances of services and/or the provision of equipment
or other goods in connection with or relating to cooling the air for combustion
turbines used in such facilities, or the retention of one or more subcontractors
to perform those services or provide that equipment or those goods, then Matrix
shall, and shall cause Brown, GSAC, its other relevant Affiliate or the relevant
customer (as applicable) to, first afford Caldwell Tanks or its designated
Affiliate the right and option to perform or provide the same services,
equipment and/or goods for the benefit of Brown, Matrix, GSAC, their Affiliate
or the relevant customer (as applicable) as would be performed or provided by
Brown, Matrix, GSAC, their Affiliate or the relevant subcontractor(s), upon
terms that are no less favorable to Caldwell Tanks (or such Affiliate) than
those available to Brown, Matrix, GSAC, their Affiliate or the relevant
subcontractor(s). Matrix agrees to promptly notify Caldwell Tanks of each
opportunity to provide such services, equipment or goods, and shall include with
such notice a copy of any relevant contract(s) or subcontract(s), and a
description in reasonable detail of the nature of the services, equipment and/or
goods to be provided and the terms and conditions thereof. Caldwell Tanks shall
have a period of ten (10) days following its receipt of all such information to
exercise its right and option upon written notice delivered to Matrix or the
relevant customer (in the case of a right and option directly granted by that
customer).

          1.2  Caldwell and Caldwell Tanks Covenants Not to Compete.  Caldwell

install, market, sell, design, lease or license, operate, maintain or repair
above-ground petroleum storage tanks for the petro-chemical industry anywhere
within the Territory, whether for its own account or for the account of any
other Person (other than for Matrix or its Affiliates); provided, that the
covenants and agreements of Caldwell and Caldwell Tanks set forth in this
Section 1.2 shall immediately terminate and become null and void in the event,
during the above-described five-year period (a) Caldwell Tanks shall sell,
convey or transfer substantially all of its assets and properties to any
Person(s) that is not presently an Affiliate of Caldwell Tanks or of any of its
current shareholders (each a "Third-Party"), or (b) greater than 50% of the
outstanding voting common stock of Caldwell Tanks becomes owned of record or
beneficially by any one or more Third-Parties, in either case whether pursuant
to one transaction or a series of related transactions with Caldwell Tanks
and/or its current shareholders.

provided, that such activities shall not be deemed to be exclusive of any other
actions which may also violate those covenants and agreements:
