"change of control" for purposes of (1) any and all stock options for the
purchase of the Company's stock held by Executive and (2) for purposes of
Executive's Prior Employment Contract, this Agreement and any other agreement to
which the Executive is party which makes reference to a change of control of the
Company or its subsidiaries.

      NOW, THEREFORE, in consideration of the mutual promises and agreements set
forth herein, the parties hereto agree as follows:

      1.    EMPLOYMENT. During the Employment Period (as defined in Section 4
hereof), the Company shall employ Executive, and Executive shall serve, as
President and Chief Operating Officer of the Operations Division of the Company.
Executive's principal place of employment shall be at the Company's principal
corporate offices in Houston, Texas during the Employment Period.

      2.    COMPENSATION. The Company shall pay or cause to be paid to Executive
during the Employment Period an annual base salary for his services under this
Agreement of not less than $175,000, payable in equal semi-monthly installments
in accordance with the Company's normal payroll procedures. Executive's base
salary shall be subject to annual review and may be increased, depending upon
the performance of the Company and Executive, upon the recommendation of the
Chairman or the Board of Directors of the Company (hereafter "BOARD OF
DIRECTORS"). Executive shall be entitled to participate in the bonus "pool" or
other structure established for the Company's top level of management which
currently provides for a bonus up to fifty-percent of base salary if the goals
set by the Board of Directors are satisfied. Nothing contained herein shall
preclude the payment of a bonus, supplemental or incentive compensation to
Executive provided that the Board of Directors authorizes any such compensation
payment. As additional compensation to Executive for the services previously
rendered by him, the services to be rendered by him pursuant to, and Executive's
other duties and obligations arising under this Agreement, including, without
limitation, his obligations under Sections 12 and 14 hereof, the Company has
granted to Executive options to purchase 320,000 shares of common stock of the
Company, par value $.002 per share, at a strike price equal to $2.50.

Period, Executive shall devote his services full time to the business of the
Company and perform the duties and responsibilities assigned to him by the Chief
Executive Officer, Ross M. Patten, or the Board of Directors to the best of his
ability and with reasonable diligence. In determining Executive's duties and
responsibilities, Ross M. Patten and the Board of Directors shall act in good
faith and shall not assign duties and responsibilities to Executive that are not
appropriate or customary with respect to the position of Executive hereunder.
This Section 3 shall not be construed as preventing Executive from engaging in
reasonable volunteer services for charitable, educational or civic
organizations, or from investing his assets in such form or manner as will not
require a material amount of his services in the operations of the companies or
businesses in which such investments are made.

employment hereunder is always 24 months, unless Notice of Termination pursuant
to Section 7 is given by either the Company or Executive to the other party. The
Company and Executive shall each have the right to give Notice of Termination at

      substantiating documentation for expense reimbursement requests as

            Executive is also authorized to seek reimbursement for charges
      attributable to the business use of his personal aircraft up to a maximum
      of $150.00 per hour of business use. This authorization is subject to the
      restrictions, if any, that may be placed upon the use of personal aircraft
      for Company business by a Company insurance policy.

            (b)   EXPENSE ALLOWANCES. Executive shall be entitled to: (i) a car

      extent that he is eligible under the provisions thereof. Executive shall
      also be entitled to participate in any group insurance, hospitalization,
      medical, health and accident, disability or similar plan or program
      established by the Company, to the extent that he is eligible under the
      provisions thereof.

            (d)   PAID VACATION. Executive shall initially be entitled to three
      (3) weeks of paid vacation during each calendar 12-month period of

      basis). Executive shall thereafter be entitled to the number of days of
      paid vacation each year that is accorded under the Company's vacation
      policy as in effect from time to time or three (3) weeks, whichever is
      greater. Unused vacation days up to a maximum of five (5) days in one year
      shall be carried forward for a period not to exceed 12 months in
      accordance with Company's vacation policy as in effect from time to time.

      6.    RIGHTS AND PAYMENTS UPON TERMINATION. The Executive's right to
compensation and benefits for periods after the date on which his employment

be determined in accordance with this Section 6,

            (a)   MINIMUM PAYMENTS. Executive shall be entitled to the following
      payments, in addition to any payments or benefits to which the Executive
      is entitled under the terms of any employee benefit plan or the following
      provisions of this Section 6:

                  (1)   his unpaid salary for the full month in which his
            Termination Date occurred; provided, however, if Executive is
            terminated for Cause pursuant to Section 6(b) below, he shall only
            be entitled to receive his accrued but unpaid salary through his
            Termination Date; and

                  (2)   his accrued but unpaid vacation pay for the period
            ending on his Termination Date in accordance with the Company's
            vacation pay policy as in effect at such time.

            (b)   SEVERANCE PAYMENT. Notwithstanding any other provision of this
      Agreement to the contrary, in the event that: (i) Executive's employment
      hereunder is terminated by the Company at any time for any reason except
      (A) for Cause (as defined below) or (B) Executive's death or Disability
      (as defined below) or (ii) Executive terminates his own employment
      hereunder at any time for Good Reason (as defined below), then, in either
      such event, Executive shall be entitled to receive, and the Company shall
      be obligated to pay, a lump sum cash payment equal to one hundred percent
      (100%) the present value of Executive's annual salary pursuant to Section
      2 or the annual salary then being paid to him, whichever is greater. For
      purposes of the immediately preceding sentence, the "present

                                                             Initials:________

                                                             Initials:________

                                  Page 4 of 23

      value" of such annual salary shall be determined in accordance with the
      regulations under Section 280G of the Code (as defined below). Also,
      except as otherwise specifically provided in this Section 6(b), such
      severance payment shall be in addition to, and shall not reduce or offset,
      any other payments that are due to Executive from the Company or any other
      source or under any other agreements, except any severance pay plan or
      program maintained by the Company that covers employees generally. The
      provisions of this Section 6(b) shall supersede any conflicting provisions
      of this Agreement but shall not be construed to curtail, offset or limit
      Executive's rights to any other payments, whether contingent upon a Change
      in Control (as defined below) or otherwise, under the Agreement or any
      other agreement, contract, plan or other source of payment except as
      specifically provided herein. In addition, in the event of a Change in
      Control, Executive shall be entitled to receive the bonus payment
      described in Section 9 hereof, if applicable.

            Notwithstanding any provision of this Section 6(b) to the contrary,
      the Executive must first execute an appropriate release and waiver
      agreement whereby Executive agrees to release and waive, in return for the
      severance payment described in this Section 6(b), any claims that he may
      have against the Company for (1) unlawful discrimination (including,
      without limitation, age discrimination) and (2) severance pay under any
      other severance pay plan or program maintained by the Company that covers
      Executive; provided, however, such agreement shall not release or waive
      any claims that may be brought by Executive for payments that may be due
      under this Agreement, without Executive's express written consent. Any
      severance payment required under this Section 6(b) shall be paid to
      Executive within twenty (20) days after Executive executes such release
      and waiver agreement, unless the parties agree in writing before then to
      another payment date or method of payment, e.g., installment payments.
      Executive shall not be required to mitigate any damages under this Section
      6(b) or any other provision of this Agreement.

            A `Change of Control' of the Company shall be deemed to have
      occurred if any of the following shall have taken place: (a) Any Person or
      group of Persons (within the meaning of Section 13 or 14 of the Securities

      or the Lender and new directors whose election by the Board or whose
      nomination for election by the Company's shareholders was approved by a
      vote of at least majority of the directors who either were directors at
      beginning of such period or whose election or nomination was previously so
      approved) cease for any reason to constitute a

      able to agree on the choice of a physician, each shall select a physician
      who, in turn, shall select a third physician to render such certification.

                  required of Executive by the Company or its successor; or

                        (D)   the Company or its successor fails to continue in
                  effect any pension plan, health-and-accident plan, or

                  Executive with substantially equal and similar benefits), or
                  the taking of any action by the Company or its successor which
                  would adversely affect Executive's participation in or

      Executive's resignation for Good Reason or Executive's termination without
      Cause, all unvested stock options previously granted to Executive shall
      immediately vest and be exercisable as set forth below. In the event that
      there is a termination of Executive's employment hereunder for any reason,
      Executive shall be entitled to exercise any and all stock options that
      were previously granted to him by the Company, and are outstanding, vested
      and unexercised as of his Termination Date, during the exercise period
      ending on the greater of (i) two (2) years from his

                                                             Initials:________

                                                             Initials:________

                                  Page 7 of 23

      Termination Date or (ii) the expiration date of the stock option as
      specified in the stock option plan or stock option agreement, as
      applicable, notwithstanding any provision in such plan or agreement that
      provides for a more limited time period to exercise stock options
      following termination of employment; provided however, if said stock
      option plan or stock option agreement provides therein for a longer period
      of time to exercise such outstanding, vested and unexercised stock options
      following his Termination Date, then such stock option plan or agreement
      shall control and the remaining provisions of this Section 6(c) shall be
      inapplicable and without further force or effect. In the event that there
      is a termination of Executive's employment hereunder for Cause or
      Executive voluntarily resigns without Good Reason within one year from the
      date of this Agreement, Executive shall forfeit any and all stock options
      that were previously granted to him by the Company, and are unvested and
      unexercised as of his Termination Date.

            During the extension period specified in the previous paragraph, if
      applicable, the Executive shall be considered an employee of the Company
      who shall make himself available to provide consulting services to the
      Company in consideration for such extension of the option exercise period
      and any post-termination payments provided to Executive under Section 6(a)
      or (b) of this Agreement. In this regard, Executive agrees to be
      classified as an employee of the Company solely for the limited purpose of
      making himself available to provide consulting services on an as-needed
      basis; provided, however, Executive hereby specifically waives any right,
      entitlement, claim or demand to (i) any additional compensation for such
      consulting services and (ii) coverage or benefits under any of the
      Company's employee benefit plans or programs, or other perquisites, terms
      and conditions of employment, except as expressly specified in other
      provisions of this Agreement. Except as expressly provided in this Section
      6(c), the provision of consulting services by Executive shall not expand
      his rights or duties under this Agreement. Executive hereby agrees to
      provide, upon request of the Company, consulting services to the Company
      on the following terms and conditions:

            (1)   Executive will make himself available, on an as-needed basis,
                  to provide consulting services to the Company for up to three
                  (3) days per month during the period beginning on the day
                  after his Termination Date and ending on the last day of the
                  extension period for exercising stock options as provided in
                  the first paragraph of Section 6(c) above, subject to the

                        spouse, or children;

                  (C)   There is no prior commitment of Executive including,

                        affairs; and

                                                             Initials:________

                                                             Initials:________

                  (D)   No travel is required of Executive in excess of 200
                        miles round-trip.

                  Executive, in any particular instance, may waive any or all of
                  the conditions set forth in clauses (A), (B), (C) or (D) above
                  in his complete discretion. Any such waiver shall not be a
                  continuing waiver and shall not release Executive of any of
                  his rights hereunder.

            (2)   Executive agrees to provide such information, services, advice
                  and recollection of events as may from time to time be
                  reasonably requested by, or on behalf of, the Company
                  regarding corporate, regulatory or business matters of which
                  Executive may have knowledge, information or understanding,
                  including testifying truthfully in any litigation or other
                  proceedings involving the Employer, provided that (i)
                  Executive first determines that his interests are not adverse,
                  or potentially adverse, to those of the Company, and (ii) the
                  Company has indemnified Executive to his satisfaction
                  including, without limitation, for reasonable attorney's fees
                  and costs. The parties hereto agree that it is the quality,
                  and not the quantity, of the consulting services to be
                  provided by Executive that is important to the Company.

            (3)   The Company will reimburse Executive for all reasonable
                  out-of-pocket expenses incurred by Executive in the course of
                  his performance of consulting services, including, without
                  limitation, supplies, mileage and travel expenses. Executive
                  agrees not to incur any expense, obligation, or liability on
                  behalf of the Company without its prior written consent.

            (4)   The provision of consulting services by Executive for the
                  Company is non-exclusive and shall not, in any way, limit the
                  rights of Executive to seek and maintain other employment or
                  to perform compensatory services on behalf of any other person
                  or entity.

            (5)   The consulting services contemplated under this Section 6(c)
                  shall not be considered part of Executive's Employment Period
                  pursuant to Section 4, nor affect his Termination Date.

      7.    NOTICE OF TERMINATION. Any termination by the Company or the
Executive shall be communicated by Notice of Termination to the other party
hereto. For purposes of this Agreement, the term "NOTICE OF TERMINATION" means a
written notice which indicates the specific termination provision of this
Agreement relied upon and sets forth in reasonable detail the facts and

                                                             Initials:________

circumstances claimed to provide a basis for termination of the Executive's
employment under the provision so indicated.

      8.    NO MITIGATION REQUIRED. Executive shall not be required to mitigate
the amount of any payment provided for under this Agreement by seeking other
employment or in any other manner.

      9.    CHANGE IN CONTROL: REQUIREMENT OF BONUS PAYMENT IN CERTAIN
CIRCUMSTANCES.

            (a)   In the event that Executive is deemed to have received an
      "excess parachute payment" (as such term is defined in Section 280G(b) of
      the Code) which is subject to the excise taxes (the "EXCISE TAXES")
      imposed by Section 4999 of the Code in respect of any payment pursuant to
      this Agreement, or any other agreement, plan, instrument or obligation, in
      whatever form, the Company shall make the Bonus Payment (defined below) to
      Executive promptly after the date on which Executive received or is deemed
      to have received any excess parachute payment notwithstanding any contrary
      provision herein.

            (b)   The term "BONUS PAYMENT" means a cash payment in an amount
      equal to the sum of (i) all Excise Taxes payable by Executive, plus (ii)
      all additional Excise Taxes and federal or state income taxes to the
      extent such taxes are imposed in respect of the Bonus Payment, such that
      Executive shall be in the same after-tax position and shall have received
      the same benefits that he would have received if the Excise Taxes had not
      been imposed. For purposes of calculating any income taxes attributable to
      the Bonus Payment, Executive shall be deemed for all purposes to be paying
      income taxes at the highest marginal federal income tax rate, taking into
      account any applicable surtaxes and other generally applicable taxes which
      have the effect of increasing the marginal federal income tax rate and, if
      applicable, at the highest marginal state income tax rate, to which the
      Bonus Payment and Executive are subject. An example of the calculation of
      the Bonus Payment is set forth below: Assume that the Excise Tax rate is
      20%, the highest federal marginal income tax rate is 40% and Executive is
      not subject to state income taxes. Further assume that Executive has
      received an excess parachute payment in the amount of $200,000, on which
      $40,000 in Excise Taxes are payable. The amount of the required Bonus
      Payment is thus $100,000. The Bonus Payment of $100,000, less additional
      Excise Taxes on the Bonus Payment of $20,000 (i.e., 20% x $100,000) and
      income taxes of $40,000 (i.e., 40% x $100,000), yields $40,000, the amount
      of the Excise Taxes payable in respect of the original excess parachute
      payment.

            (c)   Executive agrees to reasonably cooperate with the Company to
      minimize the amount of the excess parachute payments, including, without
      limitation, assisting the Company in establishing that some or all of the
      payments received by Executive that are "contingent on a change", as
      described in Section 280G(b)(2)(A)(i) of the Code, are reasonable
      compensation for personal services actually rendered by Executive before
      the date

                                                             Initials:________

                                                             Initials:________

                                 Page 10 of 23
<PAGE>
      of such change or to be rendered by Executive on or after the date of such
      change. In the event that the Company is able to establish that the amount
      of the excess parachute payments is less than originally anticipated by
      Executive, Executive shall refund to the Company any excess Bonus Payment
      to the extent not required to pay Excise Taxes or income taxes (including
      those incurred in respect of receipt of the Bonus Payment).
      Notwithstanding the foregoing, Executive shall not be required to take any
      action which his attorney or tax advisor advises him in writing (i) is
      improper or (ii) exposes Executive to material personal liability.
      Executive may require the Company to deliver to Executive an
      indemnification agreement in form and substance satisfactory to Executive
      as a condition to taking any action required by this subsection (c).

            (d)   The Company shall make any payment required to be made under
      this Section 9 in cash and on demand. Any payment required to be paid by
      the Company under this Section 9 which is not paid within 30 days of
      receipt by the Company of Executive's written demand therefor shall
      thereafter be deemed delinquent, and the Company shall pay to Executive
      immediately upon demand interest at the highest nonusurious rate per annum
      allowed by applicable law from the date such payment becomes delinquent to
      the date of payment of such delinquent sum with interest.

            (e)   In the event that there is any change to the Code which
      results in the recodification of Section 280G or Section 4999 of the Code,
      or in the event that either such section of the Code is amended, replaced
      or supplemented by other provisions of the Code of similar import
      ("SUCCESSOR PROVISIONS"), then this Agreement shall be applied and
      enforced with respect to such new Code provisions in a manner consistent
      with the intent of the parties as expressed herein, which is to assure
      that Employee is in the same after-tax position and has received the same
      benefits that he would have been in and received if any taxes imposed by
      Section 4999 or any Successor Provisions had not been imposed.

      10.   POST-TERMINATION MEDICAL COVERAGE. If the employment of Executive is
terminated for any reason except for Cause (as defined in Section 6(b)), death
or voluntary resignation without Good Reason, then the Company shall provide
post-employment medical coverage in accordance with the terms and conditions of
this Section 10. The Company shall continue to cover Executive and his spouse
(hereinafter referred to as "SPOUSE") and his eligible dependent children, if
any, from the Termination Date until two (2) years following the Termination
Date, under the group health care plan maintained by the Company to provide
major medical insurance coverage for employees and their dependents (such group
medical plan or its successor shall be hereinafter referred to as the "HEALTH
CARE PLAN").

      Executive, on behalf of himself and his Spouse and other dependents, if
any, shall be required to pay premiums for their coverage under the Health Care
Plan at the rates, if any, charged by the Company to active employees who are
senior officers of the Company at the time the premium is charged. Any
post-employment coverage under the Health Care Plan provided under

                                                             Initials:________

                                 Page 11 of 23
<PAGE>
this Section 10 shall run concurrently with COBRA continuation coverage under
the Health Care Plan and, therefore, Executive and the other qualifying
beneficiaries shall elect any COBRA continuation coverage offered to them under
the Health Care Plan following the Termination Date. The Company shall not be
responsible for the payment of any income or other taxes which may be imposed on
Executive, or on his Spouse or dependents, as the result of receiving coverage
under the Health Care Plan pursuant to this Section 10.

      Executive, on behalf of himself and his Spouse and dependents, hereby
agrees and consents to acquire and maintain any coverage that any of them are
entitled to at any time during the two year period (as specified above in this
Section 10) under the Medicare program or any similar or succeeding plan or
program that is sponsored or maintained by the United States Government or any
agency thereof (hereinafter referred to as "MEDICARE"). The coverage described
in the immediately preceding sentence includes, without limitation, parts A and
B of Medicare and any additional or successor parts of Medicare. Executive, on
behalf of himself and his Spouse, further agrees and consents to pay all
required premiums and other costs for Medicare coverage from their personal
funds. Medicare coverage shall be primary payor to the coverage provided under
the Health Care Plan to the extent permitted by applicable federal law.

      11.   CONFLICTS OF INTEREST. In keeping with his fiduciary duties to
Company, Executive hereby agrees that he shall not become involved in a conflict
of interest, or upon discovery thereof, allow such a conflict to continue at any
time during the Employment Period. Moreover, Executive agrees that he shall
immediately disclose to the Board of Directors any facts that might involve a
conflict of interest that has not been approved by the Board of Directors.

      Executive and Company recognize and acknowledge that it is not possible to
provide an exhaustive list of actions or interests that may constitute a
"conflict of interest." Moreover, Company and Executive recognize there are many
borderline situations. In some instances, full disclosure of facts by the
Executive to the Board of Directors may be all that is necessary to enable
Company to protect its interests. In others, if no improper motivation appears
to exist and Company's interests have not demonstrably suffered, prompt
elimination of the outside interest may suffice. In other egregious instances,
it may be necessary for Company to terminate Executive's employment for Cause
pursuant to Section 6(b) hereof. The Board of Directors reserves the right to
take such action as, in its good faith judgment, will resolve the conflict of
interest.

      Executive hereby agrees that any direct or indirect interest in,
connection with, or benefit from any outside activities, particularly commercial
activities, which interest might adversely affect the Company or any of its
affiliated entities, involves a possible conflict of interest. Circumstances in
which a conflict of interest on the part of Executive would or might arise, and
which should be reported immediately to the Board of Directors, include, but are
not limited to, any of the following:

            (a)   Ownership of more than a de minimis interest in any lender,
      supplier, contractor, customer or other entity with which Company or any
      of its affiliated entities does business;

            (b)   Misuse of information, property or facilities to which
      Executive has access in a manner which is demonstrably injurious to the
      interests of Company or any of its affiliated entities, including its
      business, reputation or goodwill; or

            (c)   Materially trading in products or services connected with
      products or services designed or marketed by or for the Company or any of
      its affiliated entities.

      For purposes of this Agreement, "AFFILIATED ENTITY" means any entity which
owns or controls, is owned or controlled by, or is under common ownership or
control with, the Company.

      12.   CONFIDENTIAL INFORMATION.

            (a)   CONFIDENTIAL INFORMATION DEFINED. Executive hereby
      acknowledges that in his senior management position, he will create,
      acquire and have access to confidential information and trade secrets
      pertaining to the business of Company (hereafter "Confidential
      Information" as defined below). Executive hereby acknowledges that such
      Confidential Information is unique and valuable to Company's business and
      that Company would suffer irreparable injury if Confidential Information
      was divulged to the public or to persons or entities in competition with
      Company. Therefore, Executive hereby covenants and agrees to keep in
      strict secrecy and confidence, both during and after the Employment
      Period, any Confidential Information. Executive specifically agrees that
      he will not at any time disclose to others, use, copy or permit to be
      copied, except in pursuance of his duties on behalf of Company or with the
      prior consent of Company, Confidential Information relating to the Company
      or any of its affiliated entities. For purposes of this Agreement,
      "CONFIDENTIAL INFORMATION" shall mean and include, without limitation,
      information related to the business affairs, property, methods of
      operation, future plans, financial information, customer or client
      information, or other data which relates to the business or operations of
      Company or any of its affiliated entities, and all other information
      obtained by Executive from and during the Employment Period which concerns
      the affairs of Company or any of its affiliated entities and which Company
      has requested be held in confidence or could reasonably be expected to
      desire be held in confidence, or the disclosure of which would likely be
      embarrassing, detrimental or disadvantageous to the Company or any of its
      affiliated entities, or its and their directors, officers, employees or
      shareholders. Confidential Information, however, shall not include
      information that is at the time of receipt by Executive in the public
      domain or is otherwise generally known in the industry or subsequently
      enters the public domain or becomes generally known in the industry
      through no fault of Executive or breach of his duty under this Section 12.

            (b)   REQUIRED DISCLOSURE. In the event that Executive is required
      by law which cannot be waived to disclose any Confidential Information,
      Executive agrees that he will provide prompt notice of such potential
      disclosure to Company so that an appropriate protective order may be
      sought and/or a waiver of compliance with the provisions of this Agreement
      may be granted. In the event that (i) such protection or other remedy is
      not obtained or (ii) Company waives in writing the compliance by Executive
      with this provision, Executive agrees that he may furnish only that
      portion of the Confidential Information which Executive is advised by
      written opinion of counsel is legally required to be disclosed, and
      Executive shall exercise his best efforts to obtain assurances that
      confidential treatment will be accorded such Confidential Information.

            (c)   DELIVERY OF DOCUMENTS. Executive further agrees to deliver to
      Company at the termination of his employment, all correspondence,
      memoranda, notes, records, drawings, plans, customer lists or other
      documents, and all copies thereof made, composed or received by Executive,
      solely or jointly with others, and which are in Executive's possession,
      custody or control at such date and which relate in any manner to the
      past, present or anticipated business of Company or any of its affiliated
      entities.

            (d)   REMEDIES. In the event of a breach or threatened breach of any
      of the provisions of this Section 12, Company shall be entitled to an
      injunction ordering the return of all such documents, and any and all
      copies thereof, and restraining Executive from using or disclosing, for
      his benefit or the benefit of others, in whole or in part, any
      Confidential Information, including, but not limited to, the Confidential
      Information which such documents contain, constitute or embody. Executive
      further agrees that any breach or threatened breach of any of the
      provisions of this Section 12 would cause irreparable injury to Company,
      for which it would have no adequate remedy at law. Nothing herein shall be
      construed as prohibiting Company from pursuing any other remedies
      available to it for any such breach or threatened breach, including the
      recovery of damages.

      13.   PROPERTY RIGHTS. In keeping with his fiduciary duties to Company,
Executive hereby covenants and agrees that during his Employment Period, and for
a period of one (1) year following his Termination Date,Executive shall promptly
disclose in writing to Company any and all information, ideas, concepts,
improvements, discoveries, inventions and other intellectual properties, whether
patentable or not, and whether or not reduced to practice, which are conceived,
developed, made or acquired by Executive, either individually or jointly with
others, and which relate to the business, products or services of Company or any
of its affiliated entities. In consideration for his employment hereunder,
Executive hereby specifically sells, assigns and transfers to Company all of his
worldwide right, title and interest in and to all such information, ideas,
concepts, improvements, discoveries, inventions and other intellectual
properties.

      If during the Employment Period, Executive creates any original work of
authorship or other property fixed in any tangible medium of expression which
(a) is the subject matter of copyright (including computer programs) and (b)
relates to Company's present or planned business, products, or services, whether
such property is created solely by Executive or jointly with others, such
property shall be deemed a work for hire, with the copyright automatically
vesting in Company. To the extent that any such writing or other property is
determined not to be a work for hire for whatever reason, Executive hereby
consents and agrees to the unconditional waiver of "moral rights" in such
writing or other property, and to assign to Company all of his right, title and
interest, including copyright, in such writing or other property.

      Executive hereby agrees to (a) assist Company or its nominee at all times
in the protection of any and all property subject to this Section 13, (b) not to
disclose any such property to others without the written consent of Company or
its nominee, except as required by his employment hereunder, and (c) at the
request of Company, to execute such assignments, certificates or other interests
as Company or its nominee may from time to time deem desirable to evidence,
establish, maintain, perfect, protect or enforce its rights, title or interests
in or to any such property.

      14.   AGREEMENT NOT TO COMPETE. Executive hereby recognizes and
acknowledges that: (a) in his executive capacity with Company he will be given
knowledge of, and access to, the Confidential Information (as described in
Section 12); (b) in the event that Executive was to enter into competition with
Company, Executive's knowledge of such Confidential Information would be of
invaluable benefit to a competitor of Company, and could cause irreparable harm
to Company's business interests; and (c) Executive's consent and agreement to
enter into the noncompetition provisions and covenants set forth herein is an
integral condition of this Agreement, without which Company would not have
agreed to provide Confidential Information to Executive, nor to his
compensation, benefits, and other terms of this Agreement. Accordingly, in
consideration for his employment, compensation, benefits, access to and
entrustment of Confidential Information, the goodwill, training and experience
provided to Executive during his Employment Period, Executive hereby covenants,
consents and agrees (regardless of whether or not there has been a Change of
Control) that during the Employment Period, and for a period two (2) years after
his employment is terminated for any reason, Executive shall not, directly or
indirectly, acting alone or in conjunction with others, for his own account or
for the account of others, including, without limitation, as an officer,
director, stockholder, owner, partner, member, manager, joint venturer,
employee, promoter, consultant, agent, lender, guarantor, representative, or
otherwise:

      customer of Company for himself or any other person or entity engaged in a
      "Similar Business to Company" (as defined below);

            (b)   Engage or participate in any Similar Business to Company
      within any states of the United States in which the Company transacts
      business on Executive's termination of

      termination date (referred to herein as the "RESTRICTED AREA");

            (c)   Request or advise any service provider, supplier, or customer
      to reduce or cancel any business that it may transact with Company or any
      of its affiliated entities;

            (d)   Solicit, induce, or otherwise attempt to influence any
      employee of the Company or any of its affiliated entities, to terminate
      his or her relationship with the Company or any of its affiliated
      entities; or

            (e)   Make any statement or perform any act intended to advance an
      interest of an existing or prospective competitor of the Company or any of
      its affiliated entities in any way that demonstrably injures the
      reputation, goodwill or any other business interest of Company or any of
      its affiliated entities.

      For purposes of this Agreement, "SIMILAR BUSINESS TO COMPANY" means any
business or other enterprise that is competitive with the current or planned
businesses, products, services or operations of the Company or any of its
affiliated entities at the time of termination of Executive's employment
including, without limitation, handling, processing or transporting municipal
biosolids, industrial organic residuals and manure.

      Executive hereby agrees that the limitations set forth above on his rights
to compete with Company after his termination of employment are reasonable and
necessary for the protection of Company. In this regard, Executive specifically
agrees that such limitations as to the period of time, geographic area and types
and scopes of restriction on his activities, as specified above, are reasonable
and necessary to protect the goodwill and other business interests of Company.
However, should the time period, the geographic area or any other
non-competition provision set forth herein be deemed invalid or unenforceable in
any respect, then Executive acknowledges and agrees that, as set forth in
Section 15 hereof, reformation may be made with respect to such time period,
geographic area or other non-competition provision in order to protect Company's
reasonable business interests to the maximum permissible extent.

      15.   REMEDIES. In the event of any pending, threatened or actual breach
of any of the covenants or provisions of Section 11, 12, 13 or 14, it is
understood and agreed by Executive that the remedy at law for a breach of any of
the covenants or provisions of these Sections may be inadequate, and, therefore,
Company shall be entitled to a restraining order or injunctive relief from any
court of competent jurisdiction, in addition to any other remedies at law and in
equity. In the event that Company seeks to obtain a restraining order or
injunctive relief, Executive hereby agrees that Company shall not be required to
post any bond in connection therewith. Should a court of competent jurisdiction
or an arbitrator (pursuant to Section 25) declare any provision of Section 11,

                                                             Initials:________

                                 Page 16 of 23
<PAGE>
12, 13 or 14 to be unenforceable due to an unreasonable restriction of duration
or geographical area, or for any other reason, such court or arbitrator is
hereby granted the consent of each of Executive and the Company to reform such
provision and/or to grant the Company any relief, at law or in equity,
reasonably necessary to protect the reasonable business interests of Company or
any of its affiliated entities. Executive hereby acknowledges and agrees that
all of the covenants and other provisions of Sections 11, 12, 13 and 14 are
reasonable and necessary for the protection of the Company's reasonable business
interests. Executive hereby agrees that if the Company prevails in any action,
suit or proceeding with respect to any matter arising out of or in connection
with Section 11, 12, 13 or 14, Company shall be entitled to all equitable and
legal remedies, including, but not limited to, injunctive relief and
compensatory damages.

      16.   DEFENSE OF CLAIMS. Executive agrees that, during the Employment
Period and for a period of two (2) years after his Termination Date, upon
reasonable request from the Company, he will cooperate with the Company and its
affiliated entities in the defense of any claims or actions that may be made by
or against the Company or any of its affiliated entities that affect his prior
areas of responsibility, except if Executive's reasonable interests are adverse
to the Company (or affiliated entity) in such claim or action. To the extent
travel is required to comply with the requirements of this Section 16, the
Company shall, to the extent possible, provide Executive with notice at least 10
days prior to the date on which such travel would be required. The Company
agrees to promptly pay or reimburse Executive upon demand for all of his
reasonable travel and other direct expenses incurred, or to be reasonably
incurred, to comply with his obligations under this Section 17.

      17.   DETERMINATIONS BY THE BOARD OF DIRECTORS.

            (a)   TERMINATION OF EMPLOYMENT. Prior to a Change in Control (as
      defined in Section 6(b)), any question as to whether and when there has
      been a termination of Executive's employment, and the cause of such
      termination, shall be determined by the Board of Directors in its
      discretion.

            (b)   COMPENSATION. Prior to a Change in Control (as defined in
      Section 6(b)), any question regarding salary, bonus and other compensation
      payable to Executive pursuant to this Agreement shall be determined by the
      Board of Directors in its discretion.

      18.   WITHHOLDINGS: RIGHT OF OFFSET. Company may withhold and deduct from
any benefits and payments made or to be made pursuant to this Agreement (a) all
federal, state, local and other taxes as may be required pursuant to any law or
governmental regulation or ruling, (b) all other normal employee deductions made
with respect to Company's employees generally, and (c) any advances made to
Executive and owed to Company.

      19.   NONALIENATION. The right to receive payments under this Agreement
shall not be subject in any manner to anticipation, alienation, sale, transfer,
assignment, pledge or encumbrance

by Executive, his dependents or beneficiaries, or to any other person who is or
may become entitled to receive such payments hereunder. The right to receive
payments hereunder shall not be subject to or liable for the debts, contracts,
liabilities, engagements or torts of any person who is or may become entitled to
receive such payments, nor may the same be subject to attachment or seizure by
any creditor of such person under any circumstances, and any such attempted
attachment or seizure shall be void and of no force and effect.

      20.   INCOMPETENT OR MINOR PAYEES. Should the Board of Directors determine
that any person to whom any payment is payable under this Agreement has been
determined to be legally incompetent or is a minor, any payment due hereunder
may, notwithstanding any other provision of this Agreement to the contrary, be
made in any one or more of the following ways: (a) directly to such minor or
person; (b) to the legal guardian or other duly appointed personal
representative of the person or estate of such minor or person; or (c) to such
adult or adults as have, in the good faith knowledge of the Board of Directors,
assumed custody and support of such minor or person; and any payment so made
shall constitute full and complete discharge of any liability under this
Agreement in respect to the amount paid.

      21.   SEVERABILITY. It is the desire of the parties hereto that this
Agreement be enforced to the maximum extent permitted by law, and should any
provision contained herein be held unenforceable by a court of competent
jurisdiction or arbitrator (pursuant to Section 24), the parties hereby agree
and consent that such provision shall be reformed to create a valid and
enforceable provision to the maximum extent permitted by law; provided, however,
if such provision cannot be reformed, it shall be deemed ineffective and deleted
here from without affecting any other provision of this Agreement.

      22.   TITLE AND HEADINGS; CONSTRUCTION. Titles and headings to Sections
hereof are for the purpose of reference only and shall in no way limit, define
or otherwise affect the provisions hereof. Any and all Exhibits referred to in
this Agreement are, by such reference, incorporated herein and made a part

compounds of the word "here" shall refer to the entire Agreement and not to any
particular provision hereof.

      23.   CHOICE OF LAW. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF TEXAS, WITHOUT REGARD TO THE PRINCIPLES
OF CONFLICTS OF LAW. VENUE SHALL BE LIMITED TO THE STATE AND FEDERAL COURTS

      24.   ARBITRATION.

            (a)   ARBITRABLE MATTERS. If any dispute or controversy arises
      between Executive and the Company as to their respective rights or
      obligations under this Agreement, then

                                                             Initials:________

                                                             Initials:________

                                 Page 18 of 23
<PAGE>
      either party may submit the dispute or controversy to arbitration under
      the then-current National Employment Dispute Resolution Rules of the
      American Arbitration Association (AAA) (the "RULES"); provided, however,
      the Company shall retain its rights to seek a restraining order or
      injunctive relief pursuant to Section 16. Any arbitration hereunder shall
      be conducted before a single arbitrator unless the parties mutually agree
      to a panel of three arbitrators. The site for any arbitration hereunder
      shall be in Montgomery County or Harris County, Texas, unless otherwise
      mutually agreed by the parties.

            (b)   SUBMISSION TO ARBITRATION. The party submitting any matter to
      arbitration shall do so in accordance with the Rules. Notice to the other
      party shall state the question or questions to be submitted for decision
      or award by arbitration. Notwithstanding any provision in this Section 25,
      Executive shall be entitled to seek specific performance of the
      Executive's right to be paid during the pendency of any dispute or
      controversy arising under this Agreement. In order to prevent irreparable
      harm, the arbitrator may grant temporary or permanent injunctive or other
      equitable relief for the protection of property rights.

            (c)   ARBITRATION PROCEDURES. The arbitrator shall set the date,
      time and place for each hearing, and shall give the parties advance
      written notice in accordance with the Rules. Any party may be represented
      by counsel or other authorized representative at any hearing. The
      arbitration shall be governed by the Federal Arbitration Act, 9
      U.S.C. Sections 1 et. seq. (or its successor). The arbitrator shall
      apply the substantive law (and the law of remedies, if applicable) of the
      State of Texas to the claims asserted to the extent that the arbitrator
      determines that federal law is not controlling.

            (d)   COMPLIANCE WITH AWARD.

                  (1)   Any award of an arbitrator shall be final and binding
            upon the parties to such arbitration, and each party shall
            immediately make such changes in its conduct or provide such
            monetary payment or other relief as such award requires. The parties
            agree that the award of the arbitrator shall be final and binding
            and shall be subject only to the judicial review permitted by the
            Federal Arbitration Act.

                  (2)   The parties hereto agree that the arbitration award may
            be entered with any court having jurisdiction and the award may then
            be enforced as between the parties, without further evidentiary
            proceedings, the same as if entered by the court at the conclusion
            of a judicial proceeding in which no appeal was taken. The Company
            and the Executive hereby agree that a judgment upon any award
            rendered by an arbitrator may be enforced in other jurisdictions by
            suit on the judgment or in any other manner provided by law.

<PAGE>
            (e)   COSTS AND EXPENSES. Each party shall pay any monetary amount
      required by the arbitrator's award, and the fees, costs and expenses for
      its own counsel, witnesses and exhibits, unless otherwise determined by
      the arbitrator in the award. The compensation and costs and expenses
      assessed by the arbitrator and AAA shall be paid by the losing party
      unless otherwise determined by the arbitrator in the award. If court
      proceedings to stay litigation or compel arbitration are necessary, the
      party who unsuccessfully opposes such proceedings shall pay all associated
      costs, expenses, and attorney's fees which are reasonably incurred by the
      other party as determined by the arbitrator.

      25.   BINDING EFFECT: THIRD PARTY BENEFICIARIES. This Agreement shall be
binding upon and inure to the benefit of the parties hereto, and to their
respective heirs, executors, personal representatives, successors and permitted
assigns hereunder, but otherwise this Agreement shall not be for the benefit of
any third parties.

      26.   ENTIRE AGREEMENT AND AMENDMENT. This Agreement contains the entire
agreement of the parties with respect to Executive's employment and the other
matters covered herein; moreover, this Agreement supersedes all prior and
contemporaneous agreements and understandings, oral or written, including the
Prior Employment Contract, between the parties hereto concerning the subject
matter hereof. This Agreement may be amended, waived or terminated only by a
written instrument executed by both parties hereto.

      27.   SURVIVAL OF CERTAIN PROVISIONS. Wherever appropriate to the
intention of the parties hereto, the respective rights and obligations of said
parties, including, but not limited to, the rights and obligations set forth in
Sections 6 through 18 and 25 hereof, shall survive any termination or expiration
of this Agreement.

      28.   WAIVER OF BREACH. No waiver by either party hereto of a breach of
any provision of this Agreement by any other party, or of compliance with any
condition or provision of this Agreement to be performed by such other party,
will operate or be construed as a waiver of any subsequent breach by such other
party or any similar or dissimilar provision or condition at the same or any
subsequent time. The failure of either party hereto to take any action by reason
of any breach will not deprive such party of the right to take action at any
time while such breach continues.

      29.   SUCCESSORS AND ASSIGNS. This Agreement shall be binding upon and
inure to the benefit of Company and its affiliated entities, and its and their
successors, and upon any person or entity acquiring, whether by merger,
consolidation, purchase of assets or otherwise, all or substantially all of the
assets and business of Company. Any reference herein to "Company" shall mean the
Company as first written above, as well as any successor or successors thereto.

hereunder without the consent of the

preceding provisions of this paragraph, this Agreement shall be binding upon and

                    EMPLOYMENT AND CONFIDENTIALITY AGREEMENT

      THIS EMPLOYMENT AND CONFIDENTIALITY AGREEMENT (this "Agreement") is made
between Synagro - WWT, Inc. ("Synagro "), a Maryland corporation with its
principal place of business at 1111 Benfield Blvd., Millersville, MD. 21108, and
JAMES P. CARMICHAEL, residing at 14 Thomasina Lane, Darien, CT
06820.("CARMICHAEL").

      WHEREAS, Synagro Technologies, Inc. ("Synagro Technologies") has purchased
all the outstanding capital stock of Wheelabrator Water Technologies, Inc., a
Maryland corporation, and various other Waste Management subsidiaries
(collectively "BIO GRO") pursuant to the terms of that certain Stock Purchase
Agreement (the "Stock Purchase Agreement") by and between Synagro Technologies
and Waste Management, Inc. et.al., dated August 14, 2000 (the "Closing Date");

      WHEREAS, CARMICHAEL, Synagro and BIO GRO desire and agree to dissolve any
prior employment relationship that may have existed between BIO GRO and
CARMICHAEL prior to Synagro Technologies' acquisition of BIO GRO and formalize
the employment relationship that commenced between Synagro or one of its related
companies (collectively referred to herein as "SYNAGRO"), and CARMICHAEL
beginning upon the acquisition of BIO GRO by Synagro Technologies.

      NOW, THEREFORE, in consideration of the promises and mutual covenants
herein contained, and other good and valuable consideration, the receipt and
sufficiency of which is hereby acknowledged, it is mutually covenanted and
agreed by and between the parties as follows.

      1.    BASE COMPENSATION. For the services rendered by CARMICHAEL to
SYNAGRO, SYNAGRO, effective September 1, 2001, shall pay CARMICHAEL a base
salary at the rate of $177,718 per year (the "Base Compensation"), which will be
reviewed annually in the second quarter each year and may be increased from time
to time. Base Compensation shall be reviewed annually and increased based on
individual and company performance and is paid in equal installments in
accordance with SYNAGRO's pay policy, but not less frequently than monthly.

      2.    INCENTIVE  COMPENSATION  AND  BONUSES.  In  addition  to the  Base
Compensation,  CARMICHAEL  shall  also  receive  or  be  eligible  to  receive
additional  compensation in the form of incentive  compensation and bonuses as

per share, at an exercise price of $2.50 per share.

            (b)   BONUSES. CARMICHAEL will be eligible to participate in the
SYNAGRO bonus program that may be established from time to time. Such bonus
program changes from time to time and SYNAGRO makes no guarantee that any bonus
shall be paid. Any such bonus paid will be discretionary and based on the
financial performance of the companies and CARMICHAEL's individual job
performance as determined by SYNAGRO management. CARMICHAEL will be eligible to
participate in the bonus program at the Division President level.

                                  Page 1 of 8
<PAGE>
SYNAGRO represents that it will provide CARMICHAEL with a true copy of the bonus
Program when it is adopted by SYNAGRO for the year 2001. CARMICHAEL shall be
entitled to participate in the year 2000 bonus program pro-rated from the
Closing Date under the Stock Purchase Agreement to the end of the year at the
discretion of senior officers of SYNAGRO. In the event, during the term of this
Agreement, SYNAGRO adopts an employee stock option plan, CARMICHAEL shall be
eligible to participate in such program at the Division President level.

            (c)   COMPENSATION. All payments of salary and other compensation to
CARMICHAEL shall be made after deduction of any taxes and other amounts which

right or privilege, which action, proceeding or suspension could have a material
adverse effect on the reputation, prospects, condition or operations of SYNAGRO;

herein as the "Restricted Area"), carry on or be engaged or otherwise take part

employment term in the event CARMICHAEL has been terminated for any reason,
other than by CARMICHAEL due to SYNAGRO's material breach of this Agreement,
CARMICHAEL agrees to comply with the restrictions set forth in subparagraphs (i)
through (v) of this paragraph 10(a).

Section 10, CARMICHAEL shall be deemed to be engaged in a particular business if
he (whether alone or in association with one or more other persons) is an owner,
proprietor, partner, stockholder, officer, employee, independent contractor,
director or joint venturer of, or a consultant or lender to, or an investor in
any manner in, any person who or which is directly or indirectly engaged in such
business. Notwithstanding the foregoing provisions of this Section 10,

an affiliate of the issuer of such securities and (ii) does not, directly or
indirectly, beneficially own more than 5% of the class of which securities are a

            (c)   CARMICHAEL acknowledges and agrees that the limitations
imposed by this non-competition covenant as to time, geographical area, and
scope of activity being restrained are reasonable and do not impose a greater
restraint than is necessary to protect the goodwill or other business interest
of SYNAGRO. CARMICHAEL further acknowledges that the stock options referred to
in Section 2 and severance provisions of Section 3 above are given in exchange
for the terms and conditions of this Agreement and to compensate CARMICHAEL for
the reductions in value between this Agreement and his prior employment
agreement with BIO GRO.

or other fiduciary or is directly or indirectly the beneficial owner of 10% or
more of any class of equity security thereof or other financial interest
therein; (ii) if such person is an individual, the spouse of such individual,
and any entity of which his spouse is an executive officer, director, partner,
trustee or other fiduciary or is directly or indirectly the beneficial owner of
10% or more of any class of equity security thereof or other financial interest
therein; (iii) if such person is an entity, any director, executive officer,
partner, trustee or other fiduciary or any direct or indirect beneficial owner
of 10% or more of any class of equity security of, or other financial interest
in, such entity; or (iv) any person that directly, or indirectly through one or
more intermediaries, controls, is controlled by, or is under common control with
the person specified. For purposes of this definition, "control" (including

the management and policies of a person, whether through the ownership of voting
securities, by contract or otherwise.

waste disposal.

      11.   REMEDIES. CARMICHAEL agrees that this Agreement is intended to
protect and preserve legitimate business interests of SYNAGRO. It is further
agreed that any breach of this Agreement may render irreparable harm to SYNAGRO.
In the event of a breach by CARMICHAEL, SYNAGRO shall have available to it all
remedies provided by law, including, but not limited to, permanent injunctive
relief to restrain CARMICHAEL from violating this Agreement. SYNAGRO shall also
be entitled to commence legal action against CARMICHAEL for any breach of any
confidentiality agreement and/or confidentiality programs in effect at any time
between CARMICHAEL and SYNAGRO. Notwithstanding any legal remedies available to
SYNAGRO as a result of a breach of this Agreement, in the event of a breach by
CARMICHAEL, SYNAGRO shall immediately be entitled to withhold and avoid payment
of any sums of money or other benefits then due or to become due under this or
any other Agreement between CARMICHAEL and SYNAGRO.

      12.   REFORMATION OF COVENANTS. CARMICHAEL acknowledges that the covenants
contained in Sections 9 and 10 are reasonable in geographical and temporal scope
and in all other respects. If any court determines that any of such covenants,
or any part thereof, are unenforceable, then (a) the remainder of such covenants
shall not be affected by such determination and (b) those

                                  Page 6 of 8
<PAGE>
of such covenants that are determined to be unenforceable because of the
duration or scope thereof shall be reformed by the court to reduce their
duration or scope so as to render the same enforceable against CARMICHAEL.

      13.   CONFLICTS WITH EMPLOYEE HANDBOOK. CARMICHAEL understands and agrees
that it is his responsibility to obtain and read the SYNAGRO Employee Handbook
and to abide by the rules, policies, and standards set forth in this Employee
Handbook. CARMICHAEL also acknowledges that Synagro reserves the right to
revise, delete, and add to the provisions of the SYNAGRO Employee Handbook.
Before implementation, all such revisions, deletions, or additions to this
Employee Handbook must be in writing and must be signed by the Chief Executive
Officer, President, or Chief Financial Officer of SYNAGRO. No oral statements or
representations can change the provisions of the SYNAGRO Employee Handbook or
this employment agreement. CARMICHAEL and SYNAGRO further understand that
CARMICHAEL's employment agreement controls in the event of any conflicts with
the SYNAGRO Employee Handbook.

      14.   GENERAL PROVISIONS.

         a. NO WAIVER. The failure of SYNAGRO to terminate this Agreement for

SYNAGRO's right to terminate for subsequent breaches of the same or other
