                                    AGREEMENT

         This AGREEMENT (the "Agreement") is effective as of May 1, 1999 by and
between American Eco Corporation, an Ontario, Canada corporation whose principal
executive offices are in Houston, Texas (the "Company"), and Windrush
Corporation, an Ontario Company, (the "Consultant") and John Pennie ("Pennie").

                                R E C I T A L S

         WHEREAS Consultant employs John Pennie on a full time basis as its
President;

         AND WHEREAS the Consultant has directed its President to serve as
Chairman of the Board of Directors of the Company, and previously, other
management capacities from the date of the initial engagement by the Company of
the Consultant in January of 1992.

         AND WHEREAS the Board of Directors of the Company has determined that
it is in the best interests of the Company to retain the Consultant's services
and to reinforce and encourage the continued attention and dedication of members
of the Company's management, and the Consultant to their assigned duties without
distraction in potentially disturbing circumstances arising from the possibility
of a change in control of the Company or the assertion of claims and actions
against the Company, its employees and consultants.

         AND WHEREAS both the Company and the Consultant recognize the increased
risk of litigation and other claims being asserted against officers and
directors of companies in today's business environment.

         AND WHEREAS the Bylaws of the Company require the Company to indemnify
its directors and officers to the full extent permitted by law.

         AND WHEREAS costs, limits in coverage and availability of director's
and officer's liability insurance policies and developments in the application,
amendment and enforcement of statutory and bylaw indemnification provisions
generally have raised questions concerning the adequacy and reliability of the
protection afforded to directors and officers and have increased the difficulty
of attracting and retaining qualified persons to serve as directors and
officers.

         AND WHEREAS in recognition of the Consultant and its President's need
for substantial protection against liability and to enhance and induce the
Consultant's continued service to the Company in an effective manner and the
Consultant's reliance on the Bylaws, and in part to provide the Consultant with
specific contractual assurance that the protection promised by the Bylaws will
be available to the Consultant (regardless of, among other things, any amendment
to or revocation of the Bylaws or any change in the composition of the Company's
Board of Directors or acquisition transaction relating to the Company), the
Company wishes to provide in this Agreement for the continuing Engagement of the
Consultant and the indemnification of,

President under the Company's directors' and officers' liability insurance
policies.

           AND WHEREAS the Company wishes to assure itself of the services of
the Consultant for the period provided in this Agreement and the Consultant

                 and Pennie are participating (or plans providing substantially
                 similar benefits), the taking of any action by the Company
                 which would adversely affect the Consultant and Pennie's
                 participation in or materially reduce their benefits under any
                 of such plans or deprive them of any material fringe benefit.

                 (vi) any material breach of this Agreement by the Company;
                 provided, however, that a material breach of this Agreement by

                 Consultant notifies the Company in writing of the breach and
                 stating that such breach is grounds for Company Breach, and
                 unless the Company fails to cure such breach within thirty (30)

                 ii) In lieu of any further Base Fee and Annual Profit
                 Participation for the five year period subsequent to the Date
                 of Termination, an amount equal to the product of (A) the sum
                 of the Annual Base Fee at the rate in effect as of the Date of
                 Termination, plus the average Annual Profit Participation paid
                 to the Consultant during the preceding two (2) years, or such
                 shorter period for which any Annual Profit Participation has
                 been paid), multiplied by (B) the number five (5).

             If the Consultant terminates its Engagement for Company Breach
based upon a reduction by the Company of the Consultant's Base Fee, then for
purposes of this Section 1.6(c) (Termination Without Cause or for Company
Breach), the Consultant's Base Fee as of the Date of Termination shall be deemed
to be the Consultant's Base Fee immediately prior to the said reduction that the
Consultant claims as grounds for Company Breach.

             (d) Termination Upon a Change in Control. If the Consultant
terminates their Engagement after a Change in Control pursuant to Section 1.5(d)
(Change in Control), then the Company shall pay to the Consultant as severance
pay and as liquidated damages (because actual damages are difficult to
ascertain), in a lump sum, in cash on the Date of Termination, an amount equal
to the amounts provided in Section 1.6(c) above. In addition, if the Consultant
is liable for the payment of any excise or GST taxes (the "Basic Excise Tax")
because of Section 4999 of the Internal Revenue Code of 1986 (USA), as amended
(the "Code"), and the Revenue Canada regulations, or any successor or similar
provisions, with respect to any payments or benefits received or to be received
from the Company or its affiliates, or any successor to the Company or its
affiliates, whether provided under this Agreement or otherwise, the Company
shall pay the Consultant an amount (the "Special Reimbursement") which, after
payment by the Consultant (or on the Consultant's behalf) of any federal, state,
provincial, and local taxes applicable thereto, including, without limitation,
any further excise tax under such Section 4999 of the Code, Revenue Canada
regulations, on, with respect to or resulting from the Special Reimbursement,
equal the net amount of the Basic Excise Tax. The determination of the amount of
the payment described in this Section 1.6(d) shall be made by the Company's
independent auditors acting reasonably.

             (e) No Mitigation. The Consultant shall not be required to
mitigate the amount of any payment provided for in this Section 1.6
(Compensation Upon Termination) by seeking other Engagement's or otherwise.

             (f) Liquidated Claim. The parties agree that any payments
stipulated hereunder constitute a reasonable estimate of the damages which
would be incurred in the event of termination of the Engagement of the
Consultant and in no event shall such payments be construed as a penalty.

         1.7 Death of Consultant's President. If the Consultant's President dies
prior to the expiration of this Agreement, and the Company is unwilling to
accept an alternative employee of the Consultant's to serve in a management
capacity, the obligations under this Agreement
