                         officers of the Company will be eligible to receive
                         annual bonus awards in amounts that are competitive

                                travel and other out-of-pocket expenses
                                reasonably incurred by Executive in the

                                Agreement and in accordance with the Company's
                                policy for officers, including, without
                                limitation, continuing education, license and

                                without limitation, participation in the various
                                employee benefit plans or programs provided to
                                the employees of the Company in general, subject
                                to the regular eligibility requirements with
                                respect to each of such benefit plans or
                                programs, and such other benefits or
                                prerequisites as may be approved for Executive
                                by the Board during the term of this Agreement,
                                all on a basis as favorable to Executive as may
                                be provided or offered by the Company to other
                                comparable officers (in terms of position) of
                                the Company. Notwithstanding the above, until
                                the Company establishes employee welfare and
                                pension benefit plans for its officers,
                                Executive shall participate in such plans of the
                                AMPAM Companies as may be designated.

Notwithstanding the above, the Board may offer or provide to Executive, or to
any other officer of executive of the Company or any AMPAM Company, special
compensation, benefits, and/or perquisites, in order to attract or retain that
executive of officer where the Board determine, in its discretion, that the
offer or provision of such special compensation, benefits, an/or perquisites are
in the best interests of AMPAM or any AMPAM Company. Should the Board make such
determination and offer or provide special compensation, benefits, and/or
perquisites to an officer or executive, Executive will not automatically be
entitled to such special compensation, benefits, and/or perquisites.

                         (iii)  Until such time as Executive becomes eligible
                                for a coverage under a group health plan of
                                AMPAM, the Company shall monthly reimburse
                                Executive for any COBRA continuation premiums
                                paid by Executive for his coverage after the
                                Effective Date.

         3.       Non-Competition Agreement.

                  (a)    Executive acknowledges that as a consequence of their
                         employment with the Company, he will be furnished or
                         have access to Confidential Information (as defined
                         below). Executive further recognizes that the Company's
                         willingness to enter into this Agreement is based in
                         material part on Executive's agreement to the
                         provisions of this paragraph 3 and that Executive's
                         breach of the provisions of this paragraph 3 could
                         materially damage the Company. Subject to the further
                         provisions of this Agreement, Executive will not,

                         termination of such employment for any reason, directly
                         or indirectly, for himself or on behalf of or in
                         conjunction with any other person, company,
                         partnership, corporation or business of whatever

                                capacity, whether paid or unpaid, in any

                                service business or operation, or any ancillary
                                constructing, installation or services business
                                directly relating thereto (such business and
                                operations referred to herein as the "Plumbing
                                and Mechanical Business"), in direct competition

                                employment (the "Territory");

                                knowledge after due inquiry, either called upon
                                by the AMPAM Companies or for which the AMPAM
                                Companies made an acquisition analysis, for the
                                purpose of acquiring such entity;

                                extent that the AMPAM Companies have, in the
                                past, disclosed such information to the public
                                for valid business reasons; or

                         (vi)   Testify as an expert witness in matters related
                                to the Plumbing and Mechanical Business for an

                                litigation; provided, that nothing contained in
                                this paragraph 3(a) (vi) shall interfere with
                                Executive's duty to testify as a witness if
                                required by law.

acquisition. EXECUTIVE SHALL IMMEDIATELY DISCLOSE ANY OWNERSHIP INTEREST IN ANY
BUSINESS THAT IS IN COMPETITION WITH THE AMPAM COMPANIES TO THE BOARD.

                  (b)    Because of the difficulty of measuring economic losses
                         to the Company as a result of a breach of the foregoing
                         covenant, and because of the immediate and irreparable
                         damage that could be caused to the Company for which
                         they would have no other adequate remedy, Executive
                         agrees that foregoing covenant may be enforced by the
                         Company, in the event of breach by him, by injunctions,
                         restraining orders, and orders of specific performance
                         issued by a court of competent jurisdiction. Executive
                         further agrees to waive any requirement for the
                         Company's securing or posting of any bond in connection
                         with such remedies.

                  (c)    It is agreed by the parties that the foregoing
                         covenants in this paragraph 3 impose a reasonable
                         restraint on Executive in light of the activities and
                         business of the AMPAM Companies on the date of the
                         execution of this Agreement and the current plans of
                         the AMPAM Companies; but it is also the intent of the
                         Company and Executive that, subject to paragraph 3(g)
                         hereof, such covenants be construed and enforced in
                         accordance with the changing activities, business and
                         locations of the AMPAM Companies throughout the term of
                         this covenant, whether before of after the date of
                         termination of the employment of Executive, unless the
                         Executive was conducting such new business prior to the
                         AMPAM Companies conducting such new business. For
                         example, if, during the term of Executive's employment,
                         any of the AMPAM Companies engages in new and different
                         activities, enters a new business or establishes new
                         locations for its current or new activities or business
                         in addition to or other than the activities or business
                         enumerated under the Recitals above or the locations
                         currently established therefor, then, subject to
                         paragraph 3(g) hereof, through the term of this
                         covenant Executive will be precluded from soliciting
                         the customers or executives of such new activities or
                         business or from such new location and from directly
                         competing with such new business activities, or
                         locations within 100 miles of where such new
                         activities, business or locations are conducted, unless
                         Executive was conducting such new activities or
                         business prior to any AMPAM Companies conducting such
                         new activities or business.

                  (d)    It is further agreed by the parties hereto that, in the
                         event that Executive shall cease to be employed
                         hereunder and shall enter into a business or pursue
                         other activities not in competition with the Plumbing
                         and Mechanical Business activities of the AMPAM
                         Companies or related activities or business in
                         locations the


                                       6

   7

                         operation of which, under such circumstances, does not
                         violate clause (a)(i) of this paragraph 3, and in any
                         event such new business, activities or location are not
                         in violation of this paragraph 3 or of Executive's
                         obligations under this paragraph 3, if any, Executive
                         shall not be chargeable with a violation of this
                         paragraph 3 if the AMPAM Companies shall at any time
                         after the termination of Executive's employment, enter
                         the same, similar or a competitive (i) business, (ii)
                         course of activities or (iii) location, as applicable.

                  (e)    The covenants in this paragraph 3 are severable and
                         separate, and the unenforceability of any specific
                         covenant shall not affect the provisions of any other
                         covenant. Moreover, in the event any court of competent
                         jurisdiction shall determine that the scope, time or
                         territorial restrictions set forth are unreasonable,
                         then it is the intention of the parties that such
                         restrictions be enforced to the fullest extent, which
                         the court deems reasonable, and the Agreement shall
                         thereby be reformed.

                  (f)    All of the covenants in this paragraph 3 shall be
                         construed as an agreement independent of any other
                         provision in this Agreement, and the existence of any
                         claim or cause of action of Executive against any of
                         the AMPAM Companies, whether predicated on this
                         Agreement or otherwise, shall not constitute a defense
                         to the enforcement by the Company of such covenants. It
                         is specifically agreed that the period of two years
                         (subject to the further provisions of this Agreement)
                         following termination of employment stated at the
                         beginning of this paragraph 3, during which the
                         agreements and covenants of Executive made in this
                         paragraph 3 shall be effective, shall be computed by
                         excluding from such computation any time during which
                         Executive is in violation of any provision of this
                         paragraph 3.

                  (g)    The Company and the Executive hereby agree that this
                         covenant is a material and substantial part of this
                         transaction.

         4.       Term; Termination; Rights on Termination. The term of this
                  Agreement shall begin on the Effective Date and continue for
                  five years (the "Initial Term"), unless terminated sooner as
                  herein provided; however, beginning on the fifth anniversary
                  of the Effective Date and on each anniversary thereafter the
                  term shall automatically continue for one year on the same
                  terms and conditions contained herein in effect as of the time
                  of renewal (the "Extended Term") unless not less than six
                  months prior to any such anniversary either party shall give
                  written notice to the other party that the term shall not be
                  so extended; provided further, however, upon a Change in
                  Control (as defined in paragraph 11 (e) during the Initial
                  Term or any


                                       7

   8

                  Extended Term, the term of this Agreement shall automatically
                  continue following such Change in Control for a period equal
                  to the then remaining term or two years, whichever period is
                  longer (such longer period being an Extended Term), unless
                  earlier terminated as provided in paragraph 11. This Agreement
                  and Executive's employment may be terminated in any one of the
                  followings ways:

                  (a)    Death. The death of Executive shall immediately
                         terminate this Agreement with no severance compensation
                         due Executive's estate; provided, however, for the
                         90-day period following Executive's death, the Company,
                         at its sole cost and expense, shall continue to provide
                         Executive's then qualified beneficiaries with coverage
                         under the Company's group health plan in which
                         Executive participated immediately prior to his death
                         or a successor plan thereto, subject to the terms of
                         such plan as it may be amended ("Company Health Plan").
                         Thereafter, the Company shall provide continuation of
                         coverage elections to such qualified beneficiaries as
                         are required by law.

                  (b)    Disability. If Executive becomes entitled to and
                         receives benefits under an insured long-term disability
                         plan of the AMPAM Companies (incurs a "Disability"),
                         the Company, with the approval of a majority of the
                         members of the Board may terminate this Agreement and
                         Executive's employment hereunder. In the event this
                         Agreement is terminated as a result of Executive's
                         Disability, Executive shall have no right to any
                         severance compensation; provided, however, (i) for
                         twelve months thereafter or until Executive's death, if
                         earlier, the Company shall continue to pay Executive an
                         amount equal to Executive's monthly adjusted Base
                         Salary (computed by reference to Executive's annual
                         adjusted Base Salary at the time of his termination)
                         reduced by any cash benefits payable to Executive under
                         such long term disability plan and (ii) the Company, at
                         its sole cost and expense, shall continue the coverage
                         of Executive and his qualified beneficiaries (for as
                         long as they are qualified beneficiaries thereunder)
                         under the Company Health Plan for as long as Executive
                         continues to qualify for and receive benefits under
                         such long term disability plan, but not to exceed five
                         years. Thereafter, the Company shall provide
                         continuation of coverage elections to Executive and his
                         qualified beneficiaries as required by law.

                  (c)    Cause. The Company may terminate this Agreement and
                         Executive's employment for "Cause", which shall be:


                                        8

   9

                         (1) Executive's willful and material breach of this
                         Agreement (which remains uncured at the end of such
                         30-day period); provided, that none of the following
                         shall constitute Cause for purposes of this clause (1):
                         isolated incidences of (A) bad judgment, (B)
                         negligence, or (C) any act or omission that Executive
                         believed in good faith to have been in or not opposed
                         to the interest of the Company; (2) Executive's gross
                         negligence in the performance or intentional
                         nonperformance (in either case continuing for 30 days
                         after receipt of written notice of need to cure) of any
                         of Executive's material duties and responsibilities
                         hereunder; (3) Executive's dishonesty or fraud with
                         respect to the business, reputation or affairs of the
                         AMPAM Companies; or (4) Executive's conviction of a
                         felony crime involving moral turpitude. Any termination
                         for Cause must be approved by the majority of the
                         eligible members of the Board (FOR THIS PURPOSE, ANY
                         MEMBER OF THE BOARD REASONABLY BELIEVED BY A MAJORITY
                         OF THE BOARD TO BE AT FAULT IN THE EVENTS LEADING THE
                         BOARD TO CONSIDER TERMINATING EXECUTIVE FOR CAUSE SHALL
                         ALSO BE EXCLUDED, INCLUDING EXECUTIVE IF EXECUTIVE IS A
                         MEMBER OF THE BOARD). For purposes hereof, no act, or
                         failure to act, on Executive's part shall be deemed
                         "willful" unless done, or omitted to be done, by
                         Executive not in good faith and without reasonable
                         belief that Executive's action or omission was in the
                         best interest of the Company. Notwithstanding the
                         foregoing, Executive shall not be deemed to have been
                         terminated for Cause unless and until there shall have
                         been delivered to Executive, a Notice of Termination
                         and a copy of a resolution duly adopted by the Board,
                         finding that, in the good faith opinion of the Board,
                         Executive was guilty of conduct set forth above and
                         specifying the particulars thereof in detail. In the
                         event of a termination for Cause, Executive shall have
                         no right to any severance compensation.

                         i.     The Company may not terminate Executive's
                                employment for Cause unless:

                                (1)   No fewer than 30 days prior to the Date of
                                      Termination, the Company provides
                                      Executive with written notice (the "Notice
                                      of Consideration") of its intent to
                                      consider termination of Executive's
                                      employment for Cause, including a detailed
                                      description of the specific reasons that
                                      form the basis for such consideration;

                                (2)   for a period of not less than 25 days
                                      after the date Notice of Consideration is
                                      provided, Executive shall have the
                                      opportunity to appear before the Board,

                                      9

   10

                                      with or without legal representation, at
                                      Executive's election, to present arguments
                                      and evidence on his own behalf; and

                                (3)   following the presentation to the Board as
                                      provided in (2) above or Executive's
                                      failure to appear before the Board at a
                                      date and time specified in the Notice of
                                      Consideration (which date shall not be
                                      more than 30 days after the date the
                                      Notice of Consideration is provided),
                                      Executive may be terminated for Cause only
                                      if the Board, by majority vote of its
                                      eligible voters, determines that the
                                      actions or inactions of Executive
                                      specified in the Notice of Consideration,
                                      or reasonably related and/or
                                      later-discovered actions or inactions,
                                      occurred, that such actions or inactions
                                      constitute Cause, and that Executive's
                                      employment should accordingly be
                                      terminated for Cause;

                         ii.    Unless the Company (A) complies with the
                                substantive and procedural requirements of this
                                Section 4.c. prior to a Termination of
                                Employment for Cause, and (B) concludes, in its
                                good faith discretion that Executive's action or
                                inaction specified in the Notice of Termination
                                of Employment for Cause did occur and
                                constituted Cause, any Termination of Employment
                                shall be deemed a termination without Cause for
                                all purposes of this Agreement.

                         iii.   After providing a notice of need to cure of
                                Notice of Consideration pursuant to the
                                provisions of this Section 4.c., the Board may,
                                by the affirmation vote of all of its members
                                (excluding for this purpose, Executive, if he is
                                a member of the Board, to be at fault in the
                                events leading to issuing the Notice of
                                Consideration), suspend Executive without pay
                                until a final determination pursuant to this
                                Section 4.c. has been made.

                  (d)    Without Cause or For Good Reason. Executive may only be
                         terminated without Cause and other than due to
                         Disability by the Company during either the Initial
                         Term or the Extended Term if such termination is
                         approved by the majority of the members of the Board.
                         Should Executive be terminated by the Company without
                         Cause and other than due to Disability or should
                         Executive terminate with Good Reason during the Initial
                         Term, Executive shall receive from the Company, in
                         addition to any accrued but unpaid salary, bonus and
                         benefits, in a lump sum


                                       10



   11

                         payment due on the effective date of termination, an
                         amount equivalent to the annual adjusted base salary at
                         the rate then in effect for (i) whatever time period is
                         remaining under the Initial Term (but in no event more
                         than two years) or (ii) for one year, whichever amount
                         is greater. Should Executive be terminated by the
                         Company. without Cause and other than due to Disability
                         or should the Executive terminate with Good Reasons
                         during the Extended Term, Executive shall receive from
                         the Company., in a lump sum payment due on the
                         effective date of termination, an amount equivalent to
                         the base salary at the rate then in effect for one
                         month. Further, any termination by the Company without
                         Cause or due to Disability or by Executive for Good
                         Reason whether during the Initial Term or any Extended
                         Term shall operate to shorten the period set forth in
                         paragraph 3(a) and during which the terms of paragraph
                         3 apply to one year from the date of termination of
                         employment. If Executive resigns or otherwise
                         terminates his employment without Good Reason, rather
                         than the Company terminating his employment pursuant to
                         that paragraph 4.d., Executive shall receive no
                         severance compensation.

                  e.     Executive shall have "Good Reason" to terminate his
                         employment hereunder as a consequence of any of the
                         following events, unless such event is agreed to in
                         writing by Executive: (a) a material reduction in his
                         authority, title, responsibilities or duties; (b)
                         Executive's adjusted Base Salary is reduced below that
                         in effect on the Effective Date; (c) the relocation of
                         the Company's principal Executive offices to a location
                         outside the state of Texas without a commensurate
                         adjustment in Executive's Base Annual Salary to reflect
                         any increase in cost of living as measured by comparing
                         the applicable regional or local consumer price
                         indices; (d) the assignment to Executive of any duties
                         or responsibilities which are materially inconsistent
                         with Executive's title, position or responsibilities as
                         in effect immediately prior to such assignment; (e) the
                         failure by the Company to continue in effect any
                         executive benefit plan in which Executive participates
                         and/or any perquisite provided Executive, which is
                         (are) material to Executive's total compensation and
                         benefits, unless an equitable arrangement (embodied in
                         an ongoing substitute or alternative plan) has been
                         made with respect to such plan or perquisite, or the
                         failure by the Company to continue Executive's
                         participation therein, or any action by the Company
                         which would materially reduce Executive's participation
                         therein or reward opportunities thereunder; (f) the
                         failure of the Company to obtain a satisfactory
                         agreement from any successor or assign of the Company
                         to assume and agree to perform this Agreement, as
                         contemplated in paragraph 10; or (g) a material breach
                         of this Agreement by the Company (including

                                       11

   12

                         failure of the Company to pay Executive on a timely
                         basis the amounts to which Executive is entitled under
                         this Agreement); provided, however, Good Reason shall
                         exist with respect to a matter only if such matter is
                         not corrected by the Company within 30 days of its
                         receipt of written notice of such matter from
                         Executive, and in no event shall a termination by
                         Executive occurring more than 60 days following the
                         date of an event described above be a termination for
                         Good Reason due to such event.

                  f.     If termination of Executive's employment arises out of
                         the Company's failure to pay Executive on a timely
                         basis the amounts to which Executive is entitled under
                         this Agreement or as a result of any other breach of
                         this Agreement by the Company, as determined by a court
                         of competent jurisdiction or pursuant to the provisions
                         of paragraph 18. below, the Company shall pay all
                         amounts and damages to which Executive ma be entitled
                         as a result of such breach, including interest thereon
                         and all reasonable legal fees and expenses and other
                         costs incurred by Executive to enforce his rights
                         hereunder. Further, none of the provisions of paragraph
                         3. shall apply in the event this Agreement is
                         terminated as a result off a breach by the Company.

                  g.     Resignation Without Good Reason. Executive may, without
                         Good Reason (as hereinafter defined), terminate this
                         Agreement and Executive's employment, effective 30 days
                         after written notice is provided by the Company. If
                         Executive resigns or otherwise terminates his
                         employment without Good Reason, rather than the Company
                         terminating his employment pursuant to that paragraph
                         4.d., Executive shall receive all accrued but unpaid
                         salary, bonus and benefits. Under no circumstance where
                         Executive terminates Executive's employment at the time
                         of the determination or award for eligibility.

                  h.     Upon termination of this Agreement for any reason
                         provided above, in addition to the above payments, if
                         any, Executive shall be entitled to receive all
                         compensation earned, accrued vacation and
                         reimbursements due through the effective date of
                         termination, paid to Executive in a lump sum on the
                         effective date of termination. In addition, a
                         termination of this Agreement shall not alter or impair
                         any of Executive's vested rights or benefits, if any,
                         under any (i) executive benefit plan of the AMPAM
                         Companies or (ii) deferred compensation plan,
                         including, without limitation, any stock option plan,
                         of the AMPAM Companies. In addition, notwithstanding
                         any other provision of this Agreement, upon termination
                         of this Agreement other than (i) by the Company for

                         Cause, (ii) by Executive without Good Reason and in the
                         absence of a Change in Control or (iii) at the
                         expiration of the Initial Term or any Extended Term
                         pursuant to a timely notice, all options to purchase
                         stock of the Company (or any successor thereof) and all
                         similar equity-based awards, outstanding granted or
                         issued on the date hereof shall, at the time of such
                         termination, become vested without regard to any
                         vesting schedule thereof and in the case of the
                         options, shall be exercisable for the greater of two
                         years from the date of such termination or the period
                         provided in such award. All other rights and
                         obligations of the Company and Executive under this
                         Agreement shall cease as of the effective date of
                         termination, except that Executive's obligations under
                         paragraphs 3, 5, 6, 7, and 8 herein and the Company's
                         obligations under paragraph 11. g and 14. shall survive
                         such termination in accordance with their terms, unless
                         or except as expressly provided otherwise in this
                         Agreement.

         5.       Return of Company Property. All records, designs, patents,
                  business plans, financial statements, manuals, memoranda,
                  lists and other property delivered to or compiled by Executive
                  by or on behalf of any AMPAM Companies or their

                  Likewise, all correspondence, reports, records, charts,
                  advertising materials and other similar data pertaining to the
                  business, activities or future plans of the AMPAM Companies
                  which is collected by Executive shall be delivered promptly to
                  the AMPAM. without request by it upon termination of
                  Executive's employment and Executive shall not retain any
                  copies of the same.

         6.       Intellectual Property. Executive shall disclose promptly to
                  the Company and all conceptions, ideas, designs, plans,
                  know-how, processes, improvements and other discoveries,
                  whether patentable or not, which (i) are conceived or made by
                  Executive, solely or jointly with another, during the period
                  of employment or thereafter, (ii) are directly related to the

         7.       Trade Secrets. Executive agrees that he will not, during or
                  after the term of this Agreement, disclose the specific terms
                  of the AMPAM. Companies' relationships or agreements with its
                  respective vendors or customers or any other trade secret of
                  the AMPAM Companies, whether in existence or proposed, to any
                  person, firm, partnership, corporation or business for any
                  reason or purpose whatsoever, except as required by law and
                  prior to any such disclosure Executive shall give the Company
                  prior written notice thereof and the opportunity to contest
                  such disclosure.

         8.       Confidentiality.

                  (a)    Executive acknowledges and agrees that all Confidential
                         Information (as defined below) of the Company. is
                         confidential and a valuable, special and unique asset
                         of the Company that gives the Company an advantage over
                         its actual and potential, current and future
                         competitors. Executive further acknowledges and agrees
                         that Executive owes the Company a fiduciary duty to
                         preserve and protect all Confidential Information from
                         unauthorized disclosure or unauthorized use, that
                         certain Confidential Information constitutes "trade
                         secrets" under applicable laws and, that unauthorized
                         disclosure or unauthorized use of the Confidential
                         Information would irreparably injure the Company.

                  (b)    Both during the term of Executive's employment and
                         after the termination of Executive's employment for any
                         reason (including wrongful termination), Executive
                         shall hold all Confidential Information in strict
                         confidence, and shall not use any Confidential
                         Information except for the benefit of the Company, in
                         accordance with the duties assigned to Executive.
                         Executive shall not, at any time (either during or
                         after the term of Executive's employment), disclose any
                         Confidential Information to any person or entity
                         (except other executives of the Company who have a need
                         to know the information in connection with the
                         performance of their employment duties, and who have
                         been informed of the confidential nature of the
                         confidential information and have agreed to keep it
                         confidential), or copy, reproduce, modify, transmit,
                         including electronic transmission, decompile or reverse
                         engineer any Confidential Information, or remove any
                         Confidential Information from the Company's premises,
                         without the prior written consent of the Company Board,
                         or permit any other person to do so. Executive shall
                         take reasonable precautions to protect the physical
                         security of all documents and other material containing
                         Confidential Information (regardless of the medium on
                         which the Confidential Information is stored). This
                         Agreement applies to all

                                       14





   15

                         Confidential Information, whether now known or later to
                         become known to Executive.

                  (c)    Upon the termination of Executive's employment with the
                         Company for any reason, and upon written request of the
                         Company at any other time, Executive shall promptly
                         surrender and deliver to the Company all documents and
                         other written material of any nature containing or
                         pertaining to any Confidential Information and shall
                         not retain any such document or other material. Within
                         ten days of any such written request, Executive shall
                         certify to the Company in writing that all such
                         materials have been returned.

                  (d)    As used in this Agreement, the term "Confidential
                         Information" shall mean any information or material
                         known to or used by or for the AMPAM Companies (whether
                         or not owned or developed by the AMPAM Companies and
                         whether or not developed by Executive) that is not
                         generally known to persons in the Plumbing and
                         Mechanical Business. Confidential Information includes,
                         but is not limited to, the following: all trade secrets
                         of the AMPAM Companies; all information that the AMPAM
                         Companies as marked as confidential or has otherwise
                         described to Executive (either in writing or orally) as
                         confidential; all nonpublic information concerning the
                         AMPAM Companies products, services, prospective
                         products or services, research, product designs,
                         prices, discounts, costs, marketing plans, marketing
                         techniques, market studies, test data, customers,
                         customer lists and records, suppliers and contracts;
                         all AMPAM Companies business records and plans; all
                         AMPAM Companies personnel files; all financial
                         information of or concerning the AMPAM Companies; all
                         information relating to operating system software,
                         application software, software and system methodology,
                         hardware platforms, technical information, inventions,
                         computer programs and listings, source codes, object
                         codes, copyrights and other intellectual property; all
                         technical specifications; any proprietary information
                         belonging to the AMPAM Companies; all computer hardware
                         or software manuals; all training or instruction
                         manuals; and all data and all computer system passwords
                         and user codes. For purposes hereof, Confidential
                         Information shall not include such information (i)
                         which becomes or is already known to the public through
                         no fault of Executive; or (ii) the disclosure of which
                         (x) is required by law (including regulations and
                         rulings) or the order of any competent governmental
                         authority or (y) Executive reasonably believes is
                         required in connection with the defense of a lawsuit
                         against Executive, provided that in either case, prior
                         to disclosing any information, Executive shall give
                         prior written notice thereof

                                       15

   16

                         to the Company and provide the Company with the
                         opportunity to contest such disclosure.

         9.       No Prior Agreements. Executive hereby represents and warrants
                  to the Company that the execution of this Agreement by
                  Executive and his employment by the Company and the
                  performance of his duties hereunder will not violate or be a
                  breach of any agreement, including any non-competition
                  agreement, invention or secrecy agreement, with a former
                  employer, client or any other person or entity. Further,
                  Executive agrees to indemnify the Company for any loss,
                  including, but not limited to, reasonable attorneys' fees and
                  expenses, the Company may incur based upon or arising out of
                  Executive's breach of this paragraph 9.

         10.      Assignment; Binding Effect. Executive understands that he has
                  been selected for employment by the Company on the basis of
                  his personal qualifications, experience and skills. Executive
                  agrees, therefore, that he cannot assign all or any portion of
                  his performance under this Agreement. Subject to the preceding
                  two sentences and the express provisions of paragraph 12
                  below, this Agreement shall be binding upon, inure to the
                  benefit of and be enforceable by the parties hereto and their
                  respective heirs, legal representatives, successors and
                  assigns. The Company will require any successor (whether
                  direct or indirect, by purchase, merger, consolidation or
                  otherwise) to all or substantially all of the business and
                  assets of the Company to expressly assume and agree in writing
                  reasonably satisfactory to Executive to perform this Agreement
                  in the same manner and to the same extent that the Company
                  would be required to perform it if no such succession had
                  taken place. Failure of the AMPAM Companies to obtain such
                  written agreement prior to the effectiveness of any such
                  succession shall be a material breach of this Agreement.

         11.      Change in Control

                  a.     Executive understands and acknowledges that the Company
                         may be merged or consolidated with or into another
                         entity and that such entity shall automatically succeed
                         to the rights and obligations of the Company hereunder
                         or that the Company may undergo a Change in Control (as
                         defined below). In the event a Change in Control is
                         initiated or occurs during the Initial Term or an
                         Extended Term, than the provisions of this paragraph
                         11. shall be applicable.

                  b.     In the event of a Change in Control wherein the Company
                         and Executive have not received written notice at least
                         ten business days prior to the date of the event giving
                         rise to the Change in Control from the successor to all
                         of a substantial portion of the

                                       16

   17

                         company's business and/or assets that such successor is
                         willing as of the closing to assume and agrees to
                         perform, or continue to cause the Company to perform,
                         the Company's obligations under the Agreement in the
                         same manner and to the same extent that the Company is
                         hereby required to perform, then Executive may, at
                         Executive's sole discretion, elect to terminate
                         Executive's employment on the effective date of such
                         Change in Control by providing written notice to the
                         Board at least five business days prior to the closing
                         date of the transaction giving rise to the Change in
                         Control. In such case, Executive shall be deemed to
                         have terminated Executive's employment for Good Reason
                         on such date; provided, however, the amount of the lump
                         sum severance payment due Executive shall be triple the
                         amount calculated under the terms of paragraph 4.d.,
                         but shall in no event, exceed nine times Executive's
                         Base Annual Salary as in effect at the time of the
                         termination.

                  c.     In any Change of Control situation, Executive may, at
                         Executive's sole discretion, elect to terminate
                         Executive's employment upon the effective date of such
                         Change in Control by providing written notice to the
                         Board at least five business days prior to the closing
                         of the transaction giving rise to the Change in
                         Control. In such case, Executive shall be deemed to
                         have terminated Executive's employment for Good Reason
                         on such date; provided, however, the amount of the lump
                         sum severance payment due Executive shall be double the
                         amount calculated under the terms of paragraph 4.d.,
                         but shall in no event exceed six times Executive's Base
                         Annual Salary as in effect at the time of the
                         termination.

                  d.     If, on or within two years following the effective date
                         of a Change of Control, the Company terminates
                         Executive's employment other than for Cause or
                         Disability or Executive terminates his employment for
                         Good Reason, or if Executive's employment is terminated
                         by the Company within three months before the effective
                         date of a Change in Control and it is reasonably
                         demonstrated that such termination (i) was at the
                         request of a third party that has taken steps
                         reasonably calculated to effect a Change in Control or
                         (ii) otherwise arose in connection with or anticipation
                         of a Change in Control, then Executive shall receive
                         from the Company, in a lump sum, payment due on the
                         effective date of termination, the greater of (i) the
                         equivalent of three times Executive' s Base Annual
                         Salary at the rate then in effect, or (ii) the Base
                         Salary for whatever period is then remaining on the
                         Initial Term, if any, which payment shall be in lieu of
                         any amounts otherwise payable pursuant to paragraph
                         4.d.

                                       17

   18

                  e.     A "Change in Control" shall be deemed to have occurred
                         if:

                         i.     any person, entity or group (as such terms are
                                used in Sections 13.d. and 14 (d)(2) of the
                                Securities Exchange Act of 1934, as amended (the
                                "Act)), other than persons and entities which
                                owned any capital stock of the Company at the
                                closing date of the transactions contemplated in
                                the Acquisition Agreements, the AMPAM Companies
                                or an employee benefit plan of the AMPAM
                                Companies, acquires, directly or indirectly, the
                                beneficial ownership (as defined in Section
                                13(d) of the Act) of any voting security of the
                                Company and immediately after such acquisition
                                such person, entity of group is, directly or
                                indirectly, the beneficial owner of voting
                                securities representing [35]% or more of the
                                total voting power of all of the then
                                outstanding voting securities of the Company
                                entitled to vote generally in the election of
                                directors;

                         ii.    upon the first purchase of the Company's common
                                stock pursuant to a tender or exchange
                                offer(other than a tender or exchange offer make
                                by the Company);

                         iii.   the stockholders of the Company shall approve a
                                merger, consolidation, recapitalization or
                                reorganization of the Company, or a reverse
                                stock split of outstanding voting securities, or
                                consummation of any such transaction which would
                                result in at least 75% of the total voting power
                                represented by the voting securities of the
                                surviving entity outstanding immediately after
                                such transaction being beneficially owned by the
                                holders of all of the outstanding voting
                                securities of the Company immediately prior to
                                the transactions with the voting power of each
                                such continuing holder relative to other such
                                continuing holders not substantially altered in
                                the transaction.

                         iv.    the stockholders of the Company shall approve a
                                plan of complete liquidation or dissolution of
                                the Company or an agreement for the sale or
                                disposition by the Company of all or
                                substantially all of the Company's assets; or

                         v.     if, at any time during any period of two
                                consecutive years, individuals who at the
                                beginning of such period constitute the Board
                                cease for any reason to constitute at least a
                                majority thereof, unless the election or
                                nomination for the election by the Company's
                                stockholders of each new director was approved a
                                vote of at least two-thirds of the

                                directors at the beginning of the period.

                         f.     Notwithstanding anything in this Agreement to
                                the contrary, a termination pursuant to
                                paragraph 11.b., c., or d. shall operate to
                                automatically waive in full, the non-competition
                                restrictions imposed on Executive pursuant to
                                paragraph 3.

                         g.     If it shall be determined that any payment made
                                or benefit provided to Executive in connection
                                with Change in Control (as defined in Section
                                280G of the Internal Revenue Code of 1986, as
                                amended (the "Code), or any successor thereto)
                                of the Company occurring after the Effective
                                Date and on or before the termination of this
                                Agreement, whether or not make or provided
                                pursuant to this Agreement, is subject to the
                                excise tax imposed by Section 499 of the Code,
                                the Company shall pay Executive an amount of
                                cash (the "Additional Amount") such that the net
                                amount received by Executive after paying all
                                applicable taxes on such Additional Amount and
                                any penalties, interest and other reasonable
                                costs incurred as a result of such excise tax or
                                additional payment, shall be equal to the amount
                                that Executive would have received if Section
                                4999 were not available.

         12.      No Mitigation or Offset. Executive shall not be required to
                  mitigate the amount of any AMPAM. payment provided for in this
                  Agreement by seeking other employment or otherwise. The amount
                  of any payment required to be paid to Executive by the Company
                  pursuant to this Agreement shall not be reduced by any amounts
                  that are owed to the Company by Executive, provided that
                  Executive (i) executes and delivers to the Company a
                  promissory note evidencing a promise by Executive to pay the
                  full amount of any amounts owed to the Company within 12
                  months from the date of Executive's termination of employment
                  and (ii) provides such collateral reasonably satisfactory to
                  the Company to ensure payment of such promissory note.

         13.      Release. Notwithstanding anything in this Agreement to the
                  contrary, Executive shall not be entitled to receive any
                  severance payments pursuant to paragraphs 4.or11. of this
                  Agreement unless Executive has executed (and not revoked) a
                  general release of all claims Executive may have against the
                  Company , its subsidiaries, their directors, officers and
                  employees, in a form of such release reasonably acceptable to
                  the Company.

         14.      Indemnification. In the event Executive is made a party to an
                  threatened, pending or completed action, suit or proceeding,
                  whether civil, criminal, administrative or investigative
                  (other than an action by the Company

   20

                  against Executive and a derivative action shall not be
                  considered and action by the Company), by reason of the fact
                  that he is or was performing services for the Company or any
                  of the AMPAM Companies or any present of future subsidiary
                  thereof, or as an executive officer of the AMPAM Companies
                  prior to the date of this Agreement, then the Company shall
                  indemnify Executive against all expenses (including attorneys'
                  fees), judgments, fines and amounts paid in settlement, as
                  actually and reasonably incurred by Executive in connection
                  therewith. In the event that both Executive and the Company
                  are made a party to the same third-party action, complaint,
                  suit or proceeding, the Company agrees to engage competent
                  legal representation, and Executive agrees to use the same
                  representation, provided that if counsel selected by the
                  Company shall have a conflict of interest that prevents such
                  counsel from representing Executive, Executive may engage
                  separate counsel and the Company shall pay, as incurred, all
                  reasonable attorneys' fees and reasonable expenses of such
                  separate counsel provided further, that Executive, may at any
                  time, at Executive's sole expense, hire separate counsel to
                  represent Executive in such matter. Further, while Executive
                  is expected at all times to use his best efforts to faithfully
                  discharge his duties under this Agreement, Executive cannot be
                  held liable to the Company for errors or omissions made in
                  good faith where Executive has not exhibited gross, willful
                  and wanton negligence and misconduct nor performed criminal
                  and fraudulent acts which materially damage the business of
                  the Company. The Company shall indemnify Executive against and
                  hold Executive harmless from any costs, liabilities, losses
                  and exposures for Executive's services as an executive,
                  officer and director of the Company (or any of the AMPAM
                  Companies or any successor) to the maximum extent permitted
                  under applicable law. The indemnification required by this
                  paragraph 14. shall be made by the Company by periodic
                  payments promptly as and when bills are received or
                  liabilities are incurred. The provisions of this paragraph
                  shall survive the termination of this Agreement.

         15.      Complete Agreement. This Agreement supersedes, and replaces in
                  full, all representations, ------------------- understandings
                  and agreements (oral or written) between Executive and the
                  Company or any of the AMPAM Companies or any of their
                  officers, directors or representatives existing as of the
                  Effective Date and covering the same subject matter as this
                  Agreement. This written Agreement is the final, complete and
                  exclusive statement and expression of the agreement between
                  the Company and Executive and of all the terms of this
                  Agreement, and it cannot be varied, contradicted or
                  supplemented by evidence of any prior or contemporaneous oral
                  or written agreements. This written Agreement may not be
                  modified after the Effective Date except by a further writing
                  signed by a duly authorized officer of the Company and
                  Executive, and no term of this Agreement may be waived except
                  by writing signed by the party waiving the benefit of such
                  term.

                  Without limiting the generality of the foregoing, either
                  party's failure to insist on strict compliance with this
                  Agreement shall not be deemed a waiver thereof.

         16.      Notice. Whenever any notice is required hereunder, it shall be
                  given in writing addressed as follows:

         To the Company:            American Plumbing & Mechanical, Inc

                  Notice shall be deemed given and effective on the earlier of
                  three days after the deposit in the U.S. mail of a writing
                  addressed as above and sent first class mail, certified,
                  return receipt requested, or when actually received. Either
                  party may change the address for notice by notifying the other
                  party of such change in accordance with this paragraph 16.

         17.      Severability; Headings. If any portion of this Agreement is
                  held invalid or inoperative, the other portions of this
                  Agreement shall be deemed valid and operative and, so far as
                  is reasonable and possible, effect shall be given to the
                  intent manifested by the portion held invalid or inoperative.
                  The paragraph headings herein are for reference purposes only
                  and are not intended in any way to describe, interpret, define
                  or limit the extent or intent of the Agreement or of any part
                  hereof.

         18.      Dispute Resolutions. Except with respect to injunctive relief
                  as provided in paragraph 3(b), neither party shall institute a
                  proceeding in any court or administrative agency to resolve a
                  dispute between the parties before that party has sought to
                  resolve the dispute through direct negotiation with the other
                  party. If the dispute is not resolved within two weeks after a
                  demand for direct negotiation, the parties shall attempt to
                  resolve the dispute through mediation. If the parties do not
                  promptly agree on a mediator, the parties shall request the
                  Association of Attorney Mediators in Williamson County, Texas
                  to appoint a mediator certified by the Supreme Court of Texas.

                  dispute within a reasonable period of time, as determined by
                  the mediator, the mediator shall issue a written statement to
                  the parties to that effect and any unresolved dispute or
                  controversy arising under or in connection with this Agreement
                  shall be settled exclusively by arbitration, conducted before
                  a single Arbitrator in Round Rock, Texas, in accordance with
                  the

                                       21

   22

                  Commercial Arbitration Rules of the American Arbitration
                  Association then in effect. The arbitrator shall have the
                  authority to order back-pay, severance compensation, vesting
                  of options (or cash compensation in lieu of vesting of
                  options), reimbursement of costs and expenses, including those
                  incurred to enforce this Agreement, including reasonable
                  attorneys' fees, and interest thereon in the event the
                  arbitrator determines that Executive was involuntarily
                  terminated by the Company without Disability or Cause, as
                  defined in paragraphs 4.b and 4.c., respectfully, or that the
                  Company has otherwise materially breached this Agreement. A
                  decision by a majority by the arbitrator shall be final and
                  binding. Judgment may be entered on the arbitrators' award in
                  any court having jurisdiction.

         17.      Governing Law. This Agreement shall in all respects be
                  construed according to the laws of the State of Texas without
                  regard to its conflicts of law provisions.

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

         19.      Additional Provisions The additional provision set forth in
                  Annex A hereto shall apply.

         IN WITNESS WHEREOF, the parties hereto have executed this Agreement
