                              EMPLOYMENT AGREEMENT

     This Employment Agreement (this "Agreement") is effective as of April 1,
2001, between ENCOMPASS MANAGEMENT CO., a Delaware corporation (the "Company")
and RAY NAIZER, a resident of __________ County, Texas ("Employee").  Encompass
Services Corporation, a Texas corporation ("Encompass") has joined herein solely
for the purpose of guaranteeing the performance by the Company of its
obligations hereunder, as provided in Section 28 of this Agreement.  In
consideration of the premises and the mutual covenants contained herein, the
parties agree as follows:

     1.   Employment.  The Company hereby agrees to employ Employee and Employee
hereby agrees to work for the Company as its President - Electrical Technologies
Group.  So long as Employee is employed by the Company, Employee shall devote
Employee's skill, energy and substantially all of his business-related efforts
to the faithful discharge of Employee's duties as an employee of the Company.
Employee will work from his offices in Dallas, Texas but will spend such time in
the Kansas City, Kansas office of Encompass as is required to effectively
discharge his responsibilities under this Agreement.  In providing services
hereunder, Employee shall comply with and follow all directives, policies,
standards and regulations from time to time established by the Board of
Directors of the Company or Encompass, which are applicable to the Company.  If
Employee is elected as a director or an officer of any of the Company's
Affiliates, Employee will fulfill his duties as such director or officer without
additional compensation.

     2.   Term of Employment.  Employee's employment by the Company pursuant to
this Agreement shall continue in effect for a term of two (2) years from the
date of this Agreement (the "Initial Period"), which shall be automatically
extended, without any action on the part of Employee or the Company, for
additional, successive one-year periods (each such one-year period, an
"Additional Period" and all of such one-year periods collectively, the
"Additional Periods") commencing on the second anniversary date of this
Agreement and on each anniversary date thereafter, unless either party gives
notice of non-renewal of this Agreement, as provided in Section 10(e) of this
Agreement, or otherwise terminates this Agreement, in accordance with the other
provisions of Section 10 hereof.

     3.  Representations and Warranties.  Employee represents and warrants that
Employee is under no contractual or other restrictions or obligations that will
limit in any way Employee's activities on behalf of the Company or its
Affiliates or will prohibit or limit the disclosure or use by Employee of any
information that directly or indirectly relates to the businesses of the Company
or its Affiliates, or the services to be rendered by Employee under this
Agreement.

     4.  Compensation.  Subject to the provisions of Section 10 of this
Agreement, Employee will be entitled to the compensation and benefits set forth
in this Section 4.
<PAGE>

     (a) During the Initial Period, the Company shall pay Employee an Annual
Base Salary, payable semi-monthly, in equal installments, at a rate equal to
$265,000 per year for the first calendar year or portion thereof occurring
during the term of this Agreement.  In each subsequent calendar year, or portion
thereof, occurring during the term of this Agreement, the Company shall pay to
Employee an Annual Base Salary determined by the Compensation Committee of
Encompass following its annual salary and performance review.  Employee's Annual
Base Salary for each succeeding calendar year (or portion thereof) occurring
during the term of this Agreement will be reviewed at least annually following
the fourth quarter of each calendar year of Employee's employment hereunder,
commencing after the fourth quarter of calendar year 2001.  Employee's Annual
Base Salary shall be pro-rated for any partial calendar year remaining following
the commencement of employment with the Company under this Agreement.  In the
event this Agreement is terminated or expires during any calendar year, the
amount of such Annual Base Salary owed by the Company to Employee, if any, will
be determined pursuant to Section 10 of this Agreement.

     (b) Employee shall be eligible to receive an annual bonus pursuant to the
incentive compensation program in effect, if any, from time to time for group
president level employees of the Company.  The target bonus of Employee under
such program shall not be less than 135% of Employee's Annual Base Salary in
effect for the calendar year with respect to which such bonus is earned (pro-
rated for any partial calendar year in which employment under his Agreement
commences).  The bonus, if any, will be earned for Employee's performance during
each calendar year (or portion thereof) occurring during the term of this
Agreement, but will be finally determined and paid following the closing of the
books and records of the Company for such calendar year and review of same by
the Compensation Committee of Encompass and the Company's independent auditors.
In the event this Agreement is terminated or expires during any calendar year,
the amount of such bonus, if any, owed by the Company to Employee will be
determined pursuant to Section 10 of this Agreement.

     (c) All payments of salary and other compensation to Employee shall be made
after deduction of any taxes required to be withheld with respect thereto under
applicable federal, state and local laws.

     5.   Fringe Benefits; Expenses.

     (a) During the term of employment of Employee hereunder, Employee shall
participate in all employee benefit plans sponsored by the Company for its group
president level employees, which may include, but will not be limited to, stock
purchase and stock option plans, sick leave and disability leave, health
insurance, dental insurance and pension and/or profit sharing plans; provided,
however, that except as provided below, the existence, nature, amount and
limitations of such plans shall be determined from time to time by the Board of
Directors of the Company or Encompass.

     (b) The Company will reimburse Employee for all reasonable business
expenses incurred by Employee in the scope of Employee's employment; provided,
however, that Employee must file expense reports with respect to such expenses
in accordance with the

                                      -2-
<PAGE>

Company's policies as are in effect from time to time, and any expenses
requiring the approval of any officer or the Board of Directors of the Company
or Encompass pursuant to any policies of the Company then in effect shall have
been so approved.

     (c) During the term of employment of Employee hereunder, Employee shall be
entitled to a minimum of three weeks paid vacation during each calendar year and
to paid holidays and other paid leave set forth in the Company's policies in
effect from time to time.  Any vacation not used during a calendar year may not
be used during any subsequent period. Vacation time shall be prorated for any
partial calendar year of employment.

     (d) During the term of employment of Employee hereunder, the Company will
pay all license fees, occupation taxes and reasonable educational costs and
expenses necessary to maintain Employee's good standing under any professional
licenses required in connection with Employee's employment by the Company.

     (e) During the term of this Agreement, the Company shall use its reasonable
efforts to provide to Employee (i) life insurance payable to Employee's
designated beneficiary or beneficiaries in an amount at least three times
Employee's Annual Base Salary and (ii) to the extent provided to its other group
president level employees, as such coverage may change from time to time,
disability insurance on behalf of Employee which, as a goal, shall provide for
salary continuation in the event of permanent disability in an amount equal to
the lesser of (i) 60% of Employee's Annual Base Salary, or (ii) $10,000 per
month.

     6.  Indemnification and Insurance.  The Company shall indemnify Employee
with respect to matters relating to Employee's services as an officer and/or
director of the Company or any of its Affiliates, occurring during the course
and scope of Employee's employment with the Company, to the extent and pursuant
to the procedures set forth in the Company's By-laws, and in accordance with the
terms and procedures of any other indemnification which is generally applicable
to group president level employees of the Company and that may be provided by
the Company from time to time.  The foregoing indemnity is contractual and will
survive any adverse amendment to or repeal of the By-laws.  The Company will
also cover Employee under a policy of officers' and directors' liability
insurance providing coverage that is comparable to that provided now or
hereafter to any other group president level employee of the Company.  The
provisions of this Section 6 will survive the termination of this Agreement for
any reason.

     7.  Change in Control.  If a Change of Control occurs and if during the
Protected Period, Employee's employment is terminated or not renewed pursuant to
Section 10, whether by the Company or by Employee, then the Company shall
promptly pay or otherwise provide to Employee the benefits set forth below:

     (a) An amount equal to the sum of (i) Employee's Annual Base Salary then in
effect and (ii) an amount equal to the lesser of (a) Employee's actual bonus
earned with respect to the preceding calendar year and (b) the amount of
Employee's target bonus established by the Compensation Committee of Encompass
at the beginning of the calendar year in which the Employee's employment is
terminated or not renewed, which target bonus amount shall not be

                                      -3-
<PAGE>

less that 135% of the Annual Base Salary for such year, payable in a single lump
sum by certified or bank cashier's check within 30 days of such termination; and

     (b) An amount equal to the product of (i) the maximum monthly premium
payment that may be charged to continue coverage for Employee and Employee's
dependents under the Company's health insurance plan under COBRA, and under all
life insurance and disability policies provided by the Company for Employee,
multiplied by (ii) 18.  Such amount shall be payable semi-monthly in accordance
with the Company's policies then in effect over a period of eighteen (18)
calendar months beginning in the first calendar month following the effective
date of such termination.  Any unpaid amounts under this clause (b) will cease
if Employee obtains substantially similar coverage under new employment.

Notwithstanding the foregoing, Employee shall not be entitled to any benefits
under this Section 7 if such termination is (i) due to Employee's death, (ii) by
the Company on account of Employee's disability as provided in Section 10(d)
below, (iii) by the Company for Cause or (iv) by Employee for other than Good
Reason as provided in Section 10 below.

     8.   Gross-Up of Parachute Payments.

     (a) To provide Employee with adequate protection in connection with
Employee's ongoing employment with the Company, this Agreement or other
incentive plans of the Company provide Employee with various benefits in the
event of termination of Employee's employment with the Company during the
Protected Period following a Change of Control.  If Employee's employment is
terminated or not renewed pursuant to Section 10 during a Protected Period
following a Change of Control, or otherwise in connection with a "change of
control" of Encompass, within the meaning of Section 280G of the Internal
Revenue Code of 1986, as amended (the "Code"), a portion of those benefits could
be characterized as "excess parachute payments" within the meaning of Section
280G of the Code.  The parties hereto acknowledge that the protections set forth
in this Section 8 are important, and it is agreed that Employee should not have
to bear the full burden of the excise tax that might be levied under Section
4999 of the Code or any similar provision of federal, state of local law, in the
event that any portion of the benefits payable to Employee pursuant to this
Agreement or the other incentive plans of the Company are treated as an excess
parachute payment.  The parties, therefore, have agreed as set forth in this
Section 8.

     (b) Anything in this Agreement to the contrary notwithstanding, if it shall
be determined that any payment or distribution (including income recognized by
Employee upon the early vesting of restricted property or upon the exercise of
options whose exercise date has been accelerated) by the Company or any other
Person to or for the benefit of Employee (whether paid or payable or distributed
or distributable pursuant to the terms of this Agreement or otherwise, but
determined without regard to any additional payments required under this Section
8) (a "Payment") would be subject to the excise tax imposed by Section 4999 of
the Code or any similar provision of any federal, state or local law or any
interest or penalties are incurred by Employee with respect to such excise tax
(such excise tax, together with any such interest and penalties, are hereinafter
collectively referred to as the "Excise Tax"), then the Company shall

                                      -4-
<PAGE>

pay an additional payment, not to exceed $250,000 in the aggregate (a "Gross-Up
Payment"), in an amount such that after payment by Employee of all taxes
(including any interest or penalties imposed with respect to such taxes),
including, without limitation, any income taxes (and any interest and penalties
imposed with respect thereto) and Excise Tax imposed on the Gross-Up Payment,
Employee retains an amount of the Gross-Up Payment equal to fifty percent (50%)
of the Excise Tax imposed on the Payments. Employee will bear the cost of the
remaining 50% until the aggregate Gross-Up Payments from the Company have
reached $250,000, and will thereafter bear all additional taxes, interest or
penalties.

     (c) In the event of any dispute as to the applicability or amount of any
Gross-Up Payment, all determinations required to be made under this Section 8,
including whether and when a Gross-Up Payment is required and the amount of such
Gross-Up Payment and the assumptions to be utilized in arriving at such
determination, shall be made by the independent public accounting firm regularly
employed by the Company (the "Accounting Firm") which shall provide detailed
supporting calculations both to the Company and to Employee within 15 business
days after the receipt of notice from Employee that there has been a Payment, or
such earlier time as is requested by the Company. All fees and expenses of the
Accounting Firm will be borne by the Company.  If the Accounting Firm determines
that no Excise Tax is payable by Employee, it shall furnish Employee with a
written statement that failure to report the Excise Tax on Employee's applicable
federal income tax return would not result in the imposition of a negligence or
similar penalty.  Any determination by the Accounting Firm shall be binding on
the Company and Employee unless and until a final determination is received from
the Internal Revenue Service indicating a contrary result.  As a result of
uncertainty in the application of Section 4999 of the Code at the time of the
initial determination by the Accounting Firm hereunder, it is possible that
Gross-Up Payments may not have been made by the Company that should have been
made ("Underpayment"), consistent with the calculations required to be made
hereunder.  If Employee thereafter is required to make a payment of any Excise
Tax, the Accounting Firm shall determine the amount of the Underpayment that has
occurred and any such Underpayment shall be promptly paid by the Company to or
for the benefit of Employee, consistent with the maximum limitation stated in
Section 8(b) above.  In the event it is determined by the Accounting Firm that
the Gross Payments previously made by the Company exceeded the limitations
stated in Section 8(b) above, upon written notice from the Company, accompanied
by a copy of the Accounting Firm's calculation of same, the amount of such
overpayment shall be promptly paid by Employee to the Company.

     9.   Options and Other Stock-Related Plans.    Except to the extent
otherwise provided in this Section 9 below, the terms and conditions of any
option, stock bonus, restricted stock, stock award or other stock-related plan
or program with respect to capital stock of Encompass, which may be granted to
Employee, or in which Employee may participate, shall be governed by the
applicable Encompass or Company plan, if any, and/or separate agreement(s)
between the Company or Encompass, and Employee with respect thereto.

     (a) The exercise period for vested stock options held by Employee at the
time of any termination of this Agreement shall be the greater of (i) ninety
(90) days from the effective date of termination of employment other than under
Section 10(b) of this Agreement, (ii) thirty (30)

                                      -5-
<PAGE>

days from the effective date of termination of employment under Section 10(b) of
this Agreement, (iii) the exercise period established in or under the terms of
the stock option plan or stock option agreement to which such stock options are
subject, or (iv) the exercise period established in or under the terms of any
other written agreement between Employee and Encompass or the Company with
respect to such stock options.

     10.  Termination or Non-Renewal of Employment.

     (a)  Termination by Either Party; General Provisions. Either the Company or
Employee may terminate this Agreement and Employee's employment hereunder at any
time during the term of this Agreement by delivery of written notice by the
terminating party to the other party at least thirty (30) days prior to the
effective date of such termination as set forth in such notice; provided that
notice under this Section 10(a) shall only be effective to terminate this
Agreement in situations not governed by Section 10(e) of this Agreement. Within
thirty (30) days after such termination is effective, in addition to any other
payments or benefits provided in this Section 10, the Company shall pay to
Employee an amount equal to the sum of (i) Employee's unpaid Annual Base Salary
prorated through the date of termination of this Agreement at the rate in effect
at the time of such termination, (ii) vacation pay earned pursuant to the
policies of the Company then in effect but not taken to the date of such
termination, and (iii) all other amounts previously deferred by Employee or
earned by Employee as reflected in the books and records of the Company but not
paid as of such date under all Company incentive or deferred compensation plans
or programs.

     (b)  Termination for Cause; Resignation without Good Reason. If the Company
terminates Employee's employment for Cause, or Employee terminates his
employment without Good Reason, the payments due to Employee shall be limited to
the amounts described in Section 10(a) of this Agreement.

     (c)  Termination Without Cause; Termination for Good Reason. If the Company
terminates Employee's employment without Cause (except as provided in Section
10(d) below), or if Employee terminates Employee's employment for Good Reason,
the Company shall promptly pay or otherwise provide to Employee the following
amounts in addition to those set forth in Section 10(a) of this Agreement:

          (i) An amount equal to the sum of (A) Employee's Annual Base Salary
     then in effect and (B) the lesser of (1) the amount of Employee's actual
     bonus earned with respect to the preceding calendar year and (2) the amount
     of Employee's target bonus established by the Compensation Committee of
     Encompass at the beginning of the calendar year in which such termination
     occurs, which target bonus amount shall not be less than 135% of the Annual
     Base Salary for such year, payable in a single lump sum by certified or
     bank cashier's check within 30 days of such termination; and

                                      -6-
<PAGE>

          (ii) An amount equal to the product of (A) the maximum monthly premium
     payment that may be charged to continue coverage for Employee and
     Employee's dependents under the Company's health insurance plan under
     COBRA, and under all life insurance and disability policies provided by the
     Company for Employee multiplied by (B) 18.  Such amount shall be payable
     semi-monthly in accordance with the Company's policies then in effect over
     a period of eighteen (18) calendar months beginning in the first calendar
     month following the effective date of such termination.  Any unpaid amounts
     under this clause (ii) will cease if Employee obtains substantially similar
     coverage under new employment.

     (d)  Termination on Disability. If at any time during the term of
Employee's employment hereunder, Employee is unable to perform the essential
functions of Employee's job with or without reasonable accommodation, the
Company shall continue payment of Employee's compensation as provided in Section
4 of this Agreement during the first twelve (12) month period of such disability
to the extent not covered by the Company's disability insurance policies (the
Company may offset against its obligations in this sentence the amounts actually
received by Employee under such policies). Upon the expiration of such 12 month
period, the Company, at its sole option, may continue payment of Employee's
salary for such additional periods as the Company elects, or may terminate
Employee's employment hereunder without any further compensation obligations to
Employee hereunder. If Employee should die during the term of Employee's
employment hereunder, Employee's employment and the Company's obligations
hereunder for compensation payments shall terminate as of the end of the month
in which Employee's death occurs.

     (e)  Non-Renewal of Employment; General Provisions. Either the Company or
Employee may elect not to renew Employee's employment hereunder at the end of
the Initial Period, or at the end of any Additional Period thereafter, by
delivery of written notice by the electing party to the other party at least
sixty (60) days prior to the effective date of such termination, as set forth in
such notice. Within thirty (30) days after the expiration of the employment term
(in addition to any other amounts provided in Section 10(f) below in the case of
a non-renewal by the Company), the Company shall pay to Employee an amount equal
to the sum of (i) Employee's unpaid Annual Base Salary, if any, prorated through
the date of termination of this Agreement at the rate then in effect at the time
of such non-renewal and (ii) vacation pay earned pursuant to the policies of the
Company then in effect but not taken to the date of such non-renewal. In the
event of a non-renewal by Employee, the amounts due Employee shall be limited to
the amounts specified in clause (i) and (ii) of the preceding sentence.

     (f)  Non-Renewal by the Company at End of Initial Period or Additional
Period. If the Company elects not to continue this Agreement and renew
Employee's employment as of the end of the Initial Period or an Additional
Period, and provided in the Company's reasonable good faith determination,
Employee continues to perform Employee's duties and responsibilities through the
end of such Initial Period or Additional Period, as the case may be, then the
Company shall promptly pay or otherwise provide to Employee the following
amounts in addition to those set forth in Section 10(a):

                                      -7-
<PAGE>

          (i)  An amount equal to Employee's Annual Base Salary then in effect,
     payable in a single lump sum by certified or bank cashier's check within 30
     days of such non-renewal; and

          (ii) An amount equal to the product of (A) the maximum monthly
     premium payment that may be charged to continue coverage for Employee and
     Employee's dependents under the Company's health insurance plan under
     COBRA, and under all life insurance and disability policies provided by the
     Company for Employee multiplied by (B) 12. Such amount shall be payable
     semi-monthly in accordance with the Company's policies then in effect over
     a period of twelve (12) calendar months beginning in the first calendar
     month following the effective date of such non-renewal. Any unpaid amounts
     under this clause (ii) will cease if Employee obtains substantially similar
     coverage under new employment.

     (g)  Waiver of Claims.  In the event this Agreement expires as a result of
non-renewal by the Company, or is terminated by the Company without Cause or
because Employee is unable to perform the essential functions of his or her job,
with or without reasonable accommodation, in accordance with Section 10(d)
hereof, or is terminated by Employee with Good Reason, Employee agrees to
accept, in full settlement of any and all claims, losses, damages and other
demands that Employee may have arising out of such termination or non-renewal,
as liquidated damages and not as a penalty, the payments, benefits and vesting
of rights set forth in this Agreement. Employee waives any and all rights
Employee may have to bring any cause of action or proceeding contesting any such
termination or non-renewal. Under no circumstances shall Employee be entitled to
any compensation or confirmation of any benefits under this Agreement for any
period of time following Employee's date of termination if Employee's
termination is for Cause, or Employee's election to not renew this Agreement at
the end of the Initial Period or any Additional Period, or Employee's election
to terminate his or her employment without Good Reason.

     (h)  Lock-ups, etc.  During the one (1) year period after Employee
receives the lump sum payments as provided in Section 10(c) or (f) above,
Employee shall sign any lock-up letters, standstill agreements, or other similar
documentation specifically required by an underwriter from such Employee in
connection with a public offering of securities by the Company or Encompass or
take other actions reasonably related thereto as requested by the Board of
Directors of the Company or Encompass; provided, however, that equivalent
agreements are being required of Company management and the period of any such
lock-up or standstill agreements shall not exceed the shorter of (i) 180 days or
(ii) the balance of the one (1) year period. In the event Employee fails to sign
any such letters, agreements or similar documentation or take any such action,
the Company may seek and obtain specific performance of such covenant,
including, without limitation, any injunction requiring execution thereof or the
taking of any such actions, and Employee hereby appoints the then president of
the Company in office from time to time to sign any such documents on Employee's
behalf so long as such documents are prepared on the same basis as other
shareholders generally or as all Company management shareholders.

                                      -8-

     11.  No Mitigation Obligation.  All amounts paid to Employee under this
Agreement following Employee's termination of employment and this Agreement
are acknowledged by the Company and Employee to be reasonable and to be
liquidated damages, and Employee will not be required to reduce the amount of
such payments by seeking other employment or otherwise, nor will any profits,
income, earnings or other benefits from any source whatsoever (including from
other employment) create any mitigation, offset, reduction or any other
obligation on the part of Employee under this Agreement.

     12.  Covenant Not to Compete.

     (a)  During Employee's employment with the Company or any of its
Affiliates, and thereafter during the Restricted Period, in order to help, among
other things, ensure the security of the Company's Confidential Information,
regardless of the reason for the termination of Employee's employment and this
Agreement, Employee will not engage in or carry on, directly or indirectly,
either for himself or as a member of a partnership or as a shareholder,
investor, owner, officer or director of a company or other entity, or as an
employee, agent, associate or consultant of any person, partnership, corporation
or other entity, any business in any State of the United States or in any other
part of the world that directly competes with any services or products produced,
sold, conducted, developed, or in the process of development by the Company or
its Affiliates on the date of termination of Employee's employment.

     (b)  Notwithstanding the foregoing, Employee shall not be deemed to be
in violation of Section 12(a) based solely on the ownership of less than one
percent of any class of securities of a publicly-held company whose gross assets
exceed $100,000,000.

     (c)  Employee acknowledges that (i) during the term of this Agreement,
Employee will be provided training by the Company or its Affiliates and access
to certain Confidential Information related to the business and operations of
the Company and its Affiliates and (ii) the limitations set forth herein on
Employee's rights to compete with the Company and its Affiliates are reasonable
and necessary for the protection of the Company and its Affiliates. In this
regard, Employee specifically agrees that the limitations as to period of time
and geographic area, as well as all other restrictions on Employee's activities
specified herein, are reasonable and necessary for the protection of the Company
and its Affiliates.  In particular, Employee acknowledges that the parties
anticipate that Employee will be actively seeking markets for the products and
services of the Company and its Affiliates throughout the United States and
elsewhere in the world during Employee's employment with the Company.

     (d)  Employee further agrees that during Employee's employment with
the Company or any of its Affiliates, and thereafter during the Restricted
Period, Employee shall not (i) request, induce or attempt to influence any
supplier of goods or services to the Company or any of its Affiliates to curtail
or cancel any business they may transact with the Company or any of its
Affiliates, (ii) request, induce or attempt to influence any customers or
potential customers of the Company or any of its Affiliates to curtail or cancel
any business they may transact with the Company or any of its Affiliates, or
(iii) request, induce or attempt to influence any employee of

                                      -9-
<PAGE>

the Company or any of its Affiliates to terminate his or her employment with the
Company or any of its Affiliates.

     (e)  In the event that there shall be any violation of the covenant
not to compete set forth in this Section 12, then the time limitation thereof
shall be extended for a period of time equal to the period of time during which
such violation continues; and in the event the Company is required to seek
relief from such violation in any court, board of arbitration or other tribunal,
then the covenant shall be extended for a period of time equal to the pendency
of such proceedings, including all appeals.

     (e)  In the event Employee should violate any of the terms of this
Section 12, the Company shall have the right, in addition to pursuing damages
resulting from such violation, to reimbursement of all amounts paid to Employee,
if any, pursuant to Section 10(c),  Furthermore, Employee agrees that the remedy
at law for any breach by Employee of this Section 12 will be inadequate and that
the Company shall also be entitled to injunctive relief.

     13.  Confidential Information.  During the term of Employee's
employment hereunder, and for five (5) years after Employee's termination of
employment, Employee shall not use or disclose, without the prior written
consent of the Company, Confidential Information relating to the Company or any
of its Affiliates, and upon termination of Employee's employment will return to
the Company all written materials in Employee's possession embodying such
Confidential Information.  Employee will promptly disclose to the Company all
Confidential Information, as well as any business opportunity related to the
Company which comes to Employee's attention during the term of Employee's
employment with the Company.  Employee will not take advantage of or divert any
such business opportunity for the benefit of Employee or any other Person
without the prior written consent of the Company. Employee agrees that the
remedy at law for any breach by Employee of this Section 13 will be inadequate
