                              EMPLOYMENT AGREEMENT


         This EMPLOYMENT AGREEMENT (the "Agreement") effective as of June 1,
1999 by and between American Eco Corporation, an Ontario, Canada corporation
whose principal executive offices are in Houston, Texas (the "Company"), and
Matthew D. Hill (the "Executive").

                                 R E C I T A L S

         Executive will serve as Senior Vice President - Chief Operating
Officer.

         The Chief Executive Officer of the Company has determined that it is in
the best interests of the Company to retain the Executive"s services and to
reinforce and encourage the continued attention and dedication of members of the
Company's management, including the Executive, 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 employees.

         Both the Company and the Executive recognize the increased risk of
litigation and other claims being asserted against officers and directors of
companies in today"s environment.

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

         Costs, limits in coverage and availability of directors" and officers"
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.

         In recognition of the Executive"s need for substantial protection
against personal liability to enhance and induce the Executive"s continued
service to the Company in an effective manner and the Executive"s reliance on
the Bylaws, and in part to provide the Executive with specific contractual
assurance that the protection promised by the Bylaws will be available to the
Executive (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 employment of the Executive and the
indemnification of, and the advancing of expenses to, the Executive to the full
extent (whether partial or complete) permitted by law and as set forth in this
Agreement, and, to the extent insurance is maintained, for the coverage of the
Executive under the Company's directors" and officers" liability insurance
policies.

         The Company wishes to assure itself of the services of the Executive
for the period provided in this Agreement and the Executive wishes to serve in
the employ of the Company on the terms and conditions hereinafter provided.

                           notwithstanding the foregoing, an acquisition shall
                           not constitute a Change in Control hereunder if the

                                    (6) subject to applicable law, in a Chapter
                           11 bankruptcy proceeding, the appointment of a
                           trustee or the conversion of a case involving the

         reasonable detail the basis for such termination and shall indicate
         whether termination is being made for Cause, Without Cause or for
         Disability (if the Company has terminated the Agreement) or for Company
         Breach, upon a Change in Control or Without Good Reason (if the
         Executive has terminated the Agreement).

                  (h) Date of Termination. "Date of Termination" shall mean the
         date on which Notice of Termination is sent or given under this
         Agreement.

         1.6 Compensation During Disability or Upon Termination.

                  (a) During Disability. During any period that the Executive

                  (b) Termination for Disability. If the Company shall terminate

         no further obligation to make any payment under this Agreement which
         has not already become payable, but has not yet been paid, except that
         the Company shall continue to provide the Executive with the benefits
         set forth in Section 1.6(f) (Employee Benefits) for the period
         described therein. The Company also shall make any additional payments

                  (c) Termination for Cause or Without Good Reason. If the
         Company shall terminate the Executive"s employment for Cause or if the
         Executive shall terminate his employment Without Good Reason, then the
         Company shall have no further obligation to make any payment under this
         Agreement which has not already become payable, but has not yet been
         paid, except as may otherwise be provided under the terms of any
         employee benefit programs in which the Executive is participating.

                  (d) Termination Without Cause or for Company Breach. If the
         Company shall terminate the Executive"s employment Without Cause or if
         the Executive shall terminate his employment for Company Breach, then
         the Company shall pay to the Executive, as severance pay in a lump sum
         no later than the 15th day following the Date of Termination, the
         following amounts:

                           (i) any payment of Base Salary (at the rate in effect
                  as of the Date of Termination) or Annual Bonus which has
                  already become payable, but has not yet been paid, through the
                  Date of Termination;

                           (ii) his Annual Bonus for the fiscal year in which
                  the Date of Termination occurs, as pro-rated through the Date
                  of Termination. If such Annual Bonus is dependent upon
                  financial results for the fiscal year that are unknown at the
                  Date of Termination, his Annual Bonus received for the past
                  fiscal year shall substitute as his Annual Bonus for the
                  fiscal year in which the Date of Termination occurs; and

                           (iii) in lieu of any further Base Salary and Annual
                  Bonus for periods subsequent to the Date of Termination, an
                  amount equal to the product of (A) the sum of the Executive"s
                  Base Salary at the rate in effect as of the Date of
                  Termination, multiplied by (B) the number two (2).

                  The Company shall also continue to provide the Executive with
         the employee benefits set for in Section 1.6(f) (Employee Benefits) for
         the period described therein.

                  If the Executive terminates his employment for Company Breach
         based upon a material reduction by the Company of the Executive"s Base
         Salary, then for purposes of this Section 1.6(d) (Termination Without
         Cause or for Company Breach), the Executive"s Base Salary as of the
         Date of Termination shall be deemed to be the Executive"s Base Salary
         immediately prior to the reduction that the Executive claims as grounds
         for Company Breach.

                  (e) Termination Upon a Change in Control. If the Executive
         terminates his employment after a Change in Control pursuant to Section
         1.5(e) (Change in Control), then the Company shall pay to the Executive
         as severance pay and as liquidated damages (because actual damages are
         difficult to ascertain), in a lump sum, in cash, within 15 days after
         termination, an amount equal to the amounts provided in Sections
         1.6(d)(i), (ii), and (iii) above. In addition, if the Executive is
         liable for the payment of any excise tax (the "Basic Excise Tax")
         because of Section 4999 of the Internal Revenue Code of 1986, as
         amended (the "Code"), or any successor or similar provision, with
         respect to any payments or benefits received or to be received from the
         Company or its affiliates, or any successor to the





                                       8

         Company or its affiliates, whether provided under this Agreement or
         otherwise, the Company shall pay the Executive an amount (the "Special
         Reimbursement") which, after payment by the Executive (or on the
         Executive"s behalf) of any federal, state and local taxes applicable
         thereto, including, without limitation, any further excise tax under
         such Section 4999 of the Code, 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(e) shall be made by the Company's independent auditors.

                  (f) Employee Benefits. Unless the Company terminates the
         Executive"s employment for Cause or the Executive terminates his
         employment Without Good Reason, the Company shall maintain in full
         force and effect, for the continued benefit of the Executive and, if
         applicable, his wife and children, the employee benefits set forth in
         Sections 1.4(d) (Life Insurance) and 1.4(e) (Disability Insurance), and
         any hospitalization, medical and dental coverage included in Section
         1.4(f) (Fringe Benefits and Perquisites) above that he was entitled to
         receive immediately prior to the Date of Termination (subject to the
         general terms and conditions of the plans and programs under which he
         receives such benefits) for the balance of the Term or for the period
         provided for under the terms and conditions of such plans and programs,
         whichever is longer, with the full amount of any applicable premiums to
         be borne by the Company.

                  (g) No Mitigation. The Executive shall not be required to
         mitigate the amount of any payment provided for in this Section 1.6
         (Compensation During Disability or Upon Termination) by seeking other
         employment or otherwise.

         1.7 Death of Executive. If the Executive dies prior to the expiration
of this Agreement, the obligations under this Agreement shall automatically
terminate and all compensation to which the Executive is or would have been
entitled hereunder (including without limitation under Sections 1.4(a) (Base
Salary) and 1.4(b) (Annual Bonus)) shall terminate as of the end of the month in
which the Executive"s death occurs; provided, however, that (i) the Company
shall pay to the Executive"s estate, as soon as practicable, a prorated Annual
Bonus, if earned in accordance with the Company's annual bonus plan; (ii) for
the balance of the Term, the Executive"s wife and children shall be entitled to
continue participation in the Company's group hospitalization, medical and
dental plans (if any), with the full amount of any premium to be borne by the
Company; and (iii) the Executive"s named beneficiary or beneficiaries shall
receive the benefits payable pursuant to Section 1.4(d) (Life Insurance) hereof
and such reimbursement as may have been due to the Executive pursuant to Section
1.4(h) (Payment and Reimbursement of Expenses) hereof.

                  if (x) such securities are listed on any national or regional

                  or for the benefit of any other person or entity, solicit,

         open to the Executive. Moreover, the Executive acknowledges that he has
         other means available to him for the pursuit of his livelihood.

         2.3 Injunctive Relief. Because of the Executive"s experience and
reputation in the industries in which the Company operates, and because of the
unique nature of the Confidential Information, the Executive acknowledges,
understands and agrees that the Company will suffer immediate and irreparable
harm if the Executive fails to comply with any of his obligations under Article
2 (Non-Competition and Confidentiality) of this Agreement, and that monetary
damages will be inadequate to compensate the Company for such breach.
Accordingly, the Executive agrees that the Company shall, in addition to any
other remedies available to it at law or in equity, be entitled to injunctive
relief to enforce the terms of Article 2 (Non-Competition and Confidentiality),
without the necessity of proving inadequacy of legal remedies or irreparable
harm.

                                    ARTICLE 3

                                 INDEMNIFICATION

         3.1 Basic Indemnification Arrangement.

                  (a) Claims Arising from the Executive"s Position with the
         Company. In addition to any separate agreements between the Executive
         and the Company relating to indemnification, the Company will indemnify
         and hold harmless the Executive, to the fullest extent permitted by
         applicable law, in respect of any liability, damage, cost or expense
         (including reasonable counsel fees) incurred in connection with the
         defense of any claim, action, suit or proceeding to which he is a
         party, or threat thereof, by reason of his being or having been an
         officer or director of the Company or any subsidiary or affiliate of
         the Company, or his serving or having served at the request of the
         Company as a director, officer, employee or agent of another
         corporation or of a partnership, joint venture, trust,



                                       12
<PAGE>   13

         business organization, enterprise or other entity, including service
         with respect to employee benefit plans. Without limiting the generality
         of the foregoing, the Company will pay the expenses (including
         reasonable counsel fees) of defending any such claim, action, suit or
         proceeding in advance of its final disposition.

                  (b) Contests of this Agreement. The Company agrees to pay
         promptly as incurred, to the full extent permitted by law, all legal
         fees and expenses which the Executive may reasonably incur as a result
         of any contest (regardless of the outcome thereof) by the Company, the
         Executive or others of the validity or enforceability of, or liability
         under any provision of this Agreement or any guarantee of performance
         thereof (including as a result of any contest by the Executive about
         the amount of any payment pursuant to this Agreement), plus in each
         case interest on any delayed payment at the applicable Federal rate
         provided for in Section 7872(f)(2)(A) of the Code.

                  (c) Liability Insurance. During the Term, the Company agrees
         to continue on the Executive"s behalf, directors and officers insurance
         or any other indemnity policy presently carried on behalf of the
         Executive, and further agrees to supplement any such existing policy to
         cover all actions taken by the Executive in connection with his
         employment by the Company.

                                    ARTICLE 4

                                  MISCELLANEOUS

         4.1 Period of Limitations. No legal action shall be brought and no
cause of action shall be asserted by or on behalf of the Company or any
Affiliate of the Company against the Executive, the Executive"s spouse, heirs,
executors or personal or legal representatives after the expiration of two years
from the date of accrual of such cause of action, and any claim or cause of
action of the Company or any Affiliate shall be extinguished and deemed released
unless asserted by the timely filing of a legal action within such two-year
period; provided, however, that if any shorter period of limitations is
otherwise applicable to any such cause of action such shorter period shall
govern.

         4.2 Counterparts. This Agreement may be executed in two or more
counterparts, each of which shall be deemed to be an original but all of which
together will constitute one and the same instrument.

         4.3 Indulgences, Etc. Neither the failure nor any delay on the part of
either party to exercise any right, remedy, power or privilege under this
Agreement shall operate as a waiver thereof, nor shall any single or partial
exercise of any right, remedy, power or privilege preclude any other or further
exercise of the same or of any right, remedy, power or privilege, nor shall any
waiver of any right, remedy, power, or privilege with respect to any occurrence
be construed as a waiver of such right, remedy, power or privilege with respect
to any other occurrence.

         4.4 Executive"s Sole Remedy. The Executive"s sole remedy shall be
against the Company for any claim, liability or obligation of any nature
whatsoever arising out of or relating to this Agreement or an alleged breach of
this Agreement or for any other claim arising out of the




                                       13

directors, former directors, officers, former officers, employees, former
employees, stockholders, former stockholders, agents, former agents or the
Independent Counsel in their individual capacities arising out of or relating to
any Executive Claim. The Executive hereby releases and covenants not to sue any
person other than the Company over any Executive Claim. The persons described in
this Section 4.4 (other than the Company and the Executive) shall be third-party
beneficiaries of this Agreement for purposes of enforcing the terms of this
Section 4.4 (Executive"s Sole Remedy) against the Executive.

         4.8 Headings; Index. The headings of paragraphs and Index of Defined
Terms herein are included solely for convenience of reference and shall not
control the meaning or interpretation of any of the provisions of this
Agreement.

         4.9 Governing Law. This Agreement shall be governed by and construed in
accordance with the laws of the State of Texas, without giving effect to
principles of conflict of laws.

         4.10 Dispute Resolution. Subject to the Company's right to seek
injunctive relief in court as provided in Section 2.3 (Injunctive Relief) of
this Agreement and the Executive"s right to such a judicial determination that
the Executive should be indemnified by the Company (as provided in Section
3.1(b) (Conditions) of this Agreement), any dispute, controversy or claim
arising out of or in relation to or connection with this Agreement, including
without limitation any dispute as to the construction, validity, interpretation,
enforceability or breach of this Agreement, shall be exclusively and finally
settled by arbitration, and any party may submit such dispute, controversy or
claim, including a claim for indemnification under this Section 4.10 (Dispute
Resolution), to arbitration.

                  (a) Arbitrators. The arbitration shall be heard and determined
         by one arbitrator, who shall be impartial and who shall be selected by
         mutual agreement of the parties; provided, however, that if the dispute
         involves more than $2,000,000, then the arbitration shall be heard and
         determined by three (3) arbitrators. If three (3) arbitrators are
         necessary as provided above, then (i) each side shall appoint an
         arbitrator of its choice within thirty (30) days of the submission of a
         notice of arbitration and (ii) the party-appointed arbitrators shall in
         turn appoint a presiding arbitrator of the tribunal within thirty (30)
         days following the appointment of the last party-appointed arbitrator.
         If (x) the parties cannot agree on the sole arbitrator, (y) one party
         refuses to appoint its party-appointed arbitrator within said thirty
         (30) day period or (z) the party-appointed arbitrators cannot reach
         agreement on a presiding arbitrator of the tribunal, then the
         appointing authority for the implementation of such procedure shall be
         the Senior United States District Judge for the Southern District of
         Texas, who shall appoint an independent arbitrator who does not have
         any financial interest in the dispute, controversy or claim. If the
         Senior United States District Judge for the Southern District of Texas
         refuses or fails to act as the appointing authority within ninety (90)
         days after being requested to do so, then the appointing authority
         shall be the Chief Executive Officer of the American Arbitration
         Association, who shall appoint an independent arbitrator who does not
         have any financial interest in the dispute, controversy or claim. All
         decisions and awards by the arbitration tribunal shall be made by
         majority vote.

                  (b) Proceedings. Unless otherwise expressly agreed in writing
         by the parties to the arbitration proceedings:

                           (i) The arbitration proceedings shall be held in
                  Houston, Texas, at a site chosen by mutual agreement of the
                  parties, or if the parties cannot reach agreement on a
                  location within thirty (30) days of the appointment of the
                  last arbitrator, then at a site chosen by the arbitrators;



                                       15
<PAGE>   16

                           (ii) The arbitrators shall be and remain at all times
                  wholly independent and impartial;

                           (iii) The arbitration proceedings shall be conducted
                  in accordance with the Commercial Arbitration Rules of the
                  American Arbitration Association, as amended from time to
                  time;

                           (iv) Any procedural issues not determined under the
                  arbitral rules selected pursuant to item (iii) above shall be
                  determined by the law of the place of arbitration, other than
                  those laws which would refer the matter to another
                  jurisdiction;

                           (v) The costs of the arbitration proceedings
                  (including attorneys" fees and costs) shall be borne in the
                  manner determined by the arbitrators;

                           (vi) The decision of the arbitrators shall be reduced
                  to writing; final and binding without the right of appeal; the
                  sole and exclusive remedy regarding any claims, counterclaims,
                  issues or accounting presented to the arbitrators; made and
                  promptly paid in United States dollars free of any deduction
                  or offset; and any costs or fees incident to enforcing the
                  award shall, to the maximum extent permitted by law, be
                  charged against the party resisting such enforcement;

                           (vii) The award shall include interest from the date
                  of any breach or violation of this Agreement, as determined by
                  the arbitral award, and from the date of the award until paid
                  in full, at 6% per annum; and

                           (viii) Judgment upon the award may be entered in any
                  court having jurisdiction over the person or the assets of the
                  party owing the judgment or application may be made to such
                  court for a judicial acceptance of the award and an order of
                  enforcement, as the case may be.

         4.11 Survival. The covenants and agreements of the parties set forth in
Article 2 (Non-Competition and Confidentiality), Article 3 (Indemnification) and
Article 4 (Miscellaneous) are of a continuing nature and shall survive the
expiration, termination or cancellation of this Agreement, regardless of the
reason therefor.

         4.12 No Duplication of Payments; Subrogation. The Company shall not be
liable under this Agreement to make any payment in connection with any claim
made against the Executive to the extent the Executive has otherwise actually
received payment (under any insurance policy, Bylaw or otherwise) of the amounts
otherwise indemnifiable hereunder. In the event the Executive actually receives
payment (under any insurance policy, Bylaw or otherwise) of any amount with
respect to which the Company has already indemnified or subsequently indemnifies
the Executive, the Company shall be subrogated to the extent of such payment to
all of the rights of recovery of the Executive, who shall execute all papers
required and shall do everything that may be necessary to secure such rights,
including the execution of such documents necessary to enable the Company
effectively to bring suit to enforce such rights.

         4.13 Binding Effect, Etc. This Agreement shall be binding upon and
inure to the benefit of and be enforceable by the parties hereto and their
respective successors, assigns (including any direct or indirect successor by
purchase, merger, consolidation or otherwise to all or substantially all of the
business or assets of the Company), spouses, heirs, and personal and legal
representatives. The Company shall require and cause any successor (whether
direct or indirect by purchase, merger, consolidation or otherwise) to all,
substantially all, or a substantial part, of the business or assets of the
Company, by written agreement in form and substance satisfactory to the
Executive, expressly to assume and agree to perform this Agreement in the same
manner and to the same extent that the Company would be required to perform if
no such succession had taken place. The indemnity provisions of this Agreement
shall continue in effect regardless of whether the Executive continues to serve
as an employee of the Company.

         4.14 Contribution. If the indemnity contained in this Agreement is
unavailable or insufficient to hold the Executive harmless in a Claim for an
Indemnifiable Event, then separate from and in addition to the indemnity
provided elsewhere herein, the Company shall contribute to Expenses, judgments,
penalties, fines and amounts paid in settlement actually and reasonably incurred
by or on behalf of the Executive in connection with such Claim in such
proportion as appropriately reflects the relative benefits received by, and
fault of, the Company on the one hand and the Executive on the other in the
acts, transactions or matters to which the Claim relates and other equitable
considerations.

         4.15 This Agreement supercedes and rescinds any existing employment
contracts now in effect between the Company and the Executive.
