                    AMENDED AND RESTATED EMPLOYMENT AGREEMENT

         This Amended and Restated Employment Agreement (the "Agreement"), by
and between Quanta Services, Inc., a Delaware corporation ("Employer"), and Luke
T. Spalj ("Employee"), is hereby entered into and effective as of this 21st day
of May 2003.

                                 R E C I T A L S

         A.       As of the date of this Agreement, Employer is engaged
primarily in the business of specialty electrical contracting for electric
utilities, telecommunications and cable television providers, and
transportation, commercial and industrial customers.

         B.       Employee is employed hereunder by Employer in a confidential
relationship wherein Employee, in the course of Employee's employment with
Employer, has and will continue to become familiar with and aware of non-public
information of Employer, including but not limited to, Employer's customers,
specific manner of doing business, including the processes, techniques and trade
secrets utilized by Employer, and future plans with respect thereto
("Confidential Information"), all of which has been and will be established and
maintained at great expense to Employer; this information is a trade secret and
constitutes the valuable goodwill of Employer.

                               A G R E E M E N T S

         In consideration of the mutual promises, terms, covenants and
conditions set forth herein and the performance of each, the parties hereto
hereby agree as follows:

         1.       Employment and Duties.

         (a)      Employer hereby employs Employee as President of
Telecommunications and Cable Operations of the Employer. As such, Employee shall
have responsibilities, duties and authority reasonably accorded to and expected
of a President of Telecommunications and Cable Operations of the Employer and
will report directly to the Chief Executive Officer of Employer. Employee hereby
accepts this employment upon the terms and conditions herein contained and,
subject to Paragraph 1(c) hereof, agrees to devote Employee's time, attention
and efforts to promote and further the business of Employer.

         (b)      Employee shall faithfully adhere to, execute and fulfill all
reasonable policies established by the Board of Directors of Employer (the
"Board").

<PAGE>

         (c)      Employee shall not, during the term of his employment
                  hereunder, be engaged in any other business activity pursued
                  for gain, profit or other pecuniary advantage if such activity
                  interferes with Employee's duties and responsibilities
                  hereunder. The foregoing limitations shall not be construed as
                  prohibiting Employee from making personal investments in such
                  form or manner as will neither require Employee's significant
                  services in the operation or affairs of the companies or
                  enterprises in which such investments are made nor violate the
                  terms of Paragraph 4 hereof.

         (d)      Following termination of Employee's employment with Employment
                  with Employer for any reason, Employee shall immediately
                  resign form any and all offices and positions he holds with
                  Employer or any subsidiary, or affiliated entity, of Employer.

         2.       Compensation.

         For all services rendered by Employee, Employer shall compensate
Employee during Employee's period of employment hereunder as follows:

         (a)      Base Salary. The base salary payable to Employee shall be
$300,000 per year, payable on a regular basis in accordance with Employer's
standard payroll procedures but not less than monthly. On at least an annual
basis, the Board will review Employee's performance and may make increases to
such base salary if, in its discretion, any such increase is warranted. Such
recommended increase would, in all likelihood, require approval by the Board or
a duly constituted committee thereof.

         (b)      Incentive Bonus Plan. Employee shall participate in Employer's
Management Incentive Bonus Plan for the fiscal year ending December 31, 2003 at
a level commensurate with Employee's position, and subject to adjustment
periodically based on competitive practices of the peer group used by Employer
for purposes of competitive compensation benchmarking payable in cash or
equities as determined by Employer in its sole discretion. Employee will
participate in other current and future incentive bonus plans as determined by
the Board or a duly constituted committee thereof.

         (c)      Executive Perquisites, Benefits, and Other Compensation.
Employee shall be entitled to receive additional benefits and compensation from
Employer in such form and to such extent as specified below:

                  (i)      Payment of all premiums for coverage for Employee and
         Employee's dependent family members under health, hospitalization,
         disability, dental, life and other insurance plans that Employer may
         have in effect from time to time.

                  (ii)     Reimbursement for all business travel and other
         out-of-pocket expenses reasonably incurred by Employee in the
         performance of Employee's services pursuant to this Agreement. Employee
         shall appropriately document, in reasonable detail, all reimbursable

                                                                               2

<PAGE>

         expenses upon submission of any request for reimbursement, and in a
         format and manner consistent with Employer's expense reporting policy.

                  (iii)    Employer shall provide Employee with other executive
         perquisites as may be available to or deemed appropriate for Employee
         by the Board and participation in all other Employer-wide employee
         benefits as available from time to time.

         3.       [Intentionally left blank.]

         4.       Non-Competition.

         (a)      Employee hereby agrees that Employee will not (without
Employer's consent), during the period of Employee's employment with Employer,
and for a period of one (1) year following Employee's voluntary termination with
Employer or any direct or indirect subsidiary of Employer, or the termination of
Employee's employment with Employer or any direct or indirect subsidiary of
Employer "for cause," directly or indirectly, for himself or on behalf of or in
conjunction with any other person, persons, company, partnership, corporation or
business of whatever nature:

                  (i)      engage, as an officer, director, shareholder, owner,
         partner, joint venturer or in a managerial capacity, whether as an
         employee, independent contractor, consultant or advisor or as a sales
         representative, in any business that competes with Employer or any
         direct or indirect subsidiary of Employer within 150 miles of (A) where
         Employer or any of its subsidiaries conducts business, or has conducted
         business within the past three (3) years or (B) where Employer or any
         direct or indirect subsidiary of Employer conducts business that is,
         within six (6) months prior to the date of termination of employment,
         business under his supervision or managerial authority (such areas
         being herein referred to as the "Territory");

                  (ii)     call upon any person who is, at that time, an
         employee or consultant of Employer (including the direct or indirect
         subsidiaries thereof) for the purpose or with the intent of enticing
         such employee or consultant away from or out of the employ of Employer
         (including the direct or indirect subsidiaries thereof); or

                  (iii)    call upon any person or entity which is, at that
         time, or which has been, within one (1) year prior to that time, a
         customer of Employer (including the direct or indirect subsidiaries
         thereof) within the Territory for the purpose of soliciting or selling
         products or services in direct competition with Employer or any direct
         or indirect subsidiary of Employer within the Territory.

         Notwithstanding the above, the foregoing covenant shall not be deemed
to prohibit (A) Employee from acquiring, as a passive investor with no
involvement in the operations of the business, not more than one percent (1%) of
the capital stock of a competing business, whose stock is traded on a national
securities exchange, the Nasdaq Stock market or over-the-counter, (B) the
ownership of Employee of equity interests in Rice Lake Contracting or Deerwood
Bancshares, Inc. ("Deerwood"), (C) the financing, in the ordinary course of
business, of any Competitive Business or any subcontractor of Employer by
Deerwood or an Affiliate of Deerwood.

                                                                               3

<PAGE>

         (b)      Because of the difficulty of measuring economic losses to
Employer as a result of a breach of the foregoing covenant, and because of the
immediate and irreparable damage that could be caused to Employer for which it
would have no other adequate remedy, Employee agrees that the foregoing covenant
may be enforced by Employer in the event of breach by him, by injunctions,
restraining orders, and other equitable actions.

         (c)      It is agreed by the parties that the foregoing covenants in
this Paragraph 4 impose a reasonable restraint on Employee in light of the
activities and business of Employer (including Employer's direct and indirect
subsidiaries) on the date of the execution of this Agreement and the current
plans of Employer (including Employer's direct and indirect subsidiaries); but
it is also the intent of Employer and Employee that such covenants be construed
and enforced in accordance with the changing activities, business and locations
of Employer (including Employer's direct and indirect subsidiaries) throughout
the term of this Agreement, whether before or after the date of termination of
the employment of Employee. For example, if, during the term of this Agreement,
Employer (including Employer's direct and indirect subsidiaries) engages in new
and different activities, enters a new business or establishes new locations for
its current activities or business in addition to or other than the activities
or business enumerated under the Recitals above or the locations currently
established therefor, then Employee will be precluded from soliciting the
customers or employees of such new activities or business or from such new
location and from directly competing with such new business within 100 miles of
its then-established operating location(s) through the term of this Agreement.

         It is further agreed by the parties hereto that, in the event that
Employee shall cease to be employed hereunder, and shall enter into a business
or pursue other activities not in competition with Employer (including
Employer's direct and indirect subsidiaries), or similar activities, or business
in locations the operation of which, under such circumstances, does not violate
clause (a) (i) of this Paragraph 4, and in any event such new business,
activities or location are not in violation of this Paragraph 4 or of employee's
obligations under this Paragraph 4, if any, Employee shall not be chargeable
with a violation of this Paragraph 4 if Employer (including Employer's direct
and indirect subsidiaries) shall thereafter enter the same, similar or a
competitive (i) business, (ii) course of activities or (iii) location, as
applicable.

         (d)      The covenants in this Paragraph 4 are severable and separate,
and the unenforceability of any specific covenant shall not affect the
provisions of any other covenant. Moreover, in the event any court of competent
jurisdiction shall determine that the scope, time or territorial restrictions
set forth are unreasonable, then it is the intention of the parties that such
restrictions be enforced to the fullest extent which the court deems reasonable,
and the Agreement shall be reformed in accordance therewith.

         (e)      All of the covenants in this Paragraph 4 shall be construed as
an agreement independent of any other provision in this Agreement, and the
existence of any claim or cause of action of Employee against Employer, whether
predicated on this Agreement or otherwise, shall not constitute a defense to the
enforcement by Employer of such covenants.

                                                                               4

<PAGE>

         (f)      Notwithstanding any other provision of this Agreement, if
Employee's employment is terminated by Employer for other than good cause, then
no non-competition provision shall be enforceable for any period of time
following expiration of the Severance Period as defined in Paragraph 6(d) below.

         5.       Place of Performance.

         Nothing contained herein shall be deemed to require Employee to
relocate from Employee's current residence to a geographic location other than
the Houston, Texas metropolitan area to carry out Employee's duties and
responsibilities under this Agreement.

         6.       Term; Termination; Rights on Termination.

         The term of this Agreement shall begin on the date hereof and continue
for three (3) years (the "Initial Term"), and thereafter, unless terminated
sooner as herein provided, shall automatically renew for consecutive one-year
terms on the same terms and conditions in effect as of the time of each such
renewal (each such one-year term, a "Renewal Term" and, all Renewal Terms
together with the Initial Term, the "Term"). This Agreement and/or Employee's
employment may be terminated in any one of the followings ways:

         (a)      Death. The death of Employee shall immediately terminate this
Agreement with no severance compensation due to Employee's estate.

         (b)      Disability. If, as a result of incapacity due to physical or
mental illness or injury, Employee shall have been absent from Employee's
full-time duties hereunder for four (4) consecutive months, then thirty (30)
days after receiving written notice (which notice may occur before or after the
end of such four (4) month period, but which shall not be effective earlier than
the last day of such four (4) month period), Employer may terminate Employee's
employment hereunder provided Employee is unable to resume Employee's full-time
duties at the conclusion of such notice period. Also, Employee may terminate
Employee's employment hereunder if his health should become impaired to an
extent that makes the continued performance of Employee's duties hereunder
hazardous to Employee's physical or mental health or life, provided that
Employee shall have furnished Employer with a written statement from a qualified
doctor to such effect and provided, further, that, at Employer's request made
within thirty (30) days of the date of such written statement, Employee shall
submit to an examination by a doctor selected by Employer who is reasonably
acceptable to Employee or Employee's doctor and such doctor shall have concurred
in the conclusion of Employee's doctor. In the event this Agreement is
terminated as a result of Employee's disability, Employee shall receive from
Employer, in a lump-sum payment due within ten (10) days of the effective date
of termination, the base salary at the rate then in effect for whatever time
period is remaining under the Term of this Agreement or for one (1) year,
whichever amount is greater.

         (c)      Good Cause; Good Reason. Employer may terminate the Agreement
ten (10) days after delivery of written notice to Employee for "good cause",
which shall be: (i) Employee's willful, material and irreparable breach of this
Agreement; (ii) Employee's gross negligence in the performance or intentional
nonperformance or inattention continuing for ten (10) days after receipt of

                                                                               5

<PAGE>

written notice of need to cure of any of Employee's material duties and
responsibilities hereunder; (iii) Employee's willful dishonesty, fraud or
material misconduct with respect to the business or affairs of Employer; (iv)
Employee's conviction of a felony crime; or (v) chronic alcohol abuse or illegal
drug abuse by Employee. In the event of a termination for good cause, as
enumerated above, Employee shall have no right to any severance compensation.

         Employee may terminate his employment under this Agreement ten (10)
days after delivery of written notice to Employer for "good reason", which shall
exist if, within twelve (12) months following a Change in Control, Employee (i)
is offered a Lesser Position (as defined below), or (ii) is required to relocate
in violation of Paragraph 5 of this Agreement. "Lesser Position" shall mean a
new position or a change in the Employee's position, which, compared with
Employee's position with Employer immediately prior to the Change in Control,
(i) offers a lower level of compensation (including base salary, fringe benefits
and target bonuses under any corporate-performance based bonus or incentive
programs), or (ii) materially reduces Employee's duties or level of
responsibility. In the event of such a termination of his employment, Employee
shall be entitled to receive severance benefits as provided in Paragraph 13 (d)
below.

         (d)      Without Good Cause. At any time after the commencement of
employment, either Employee or Employer may, without good reason or good cause,
respectively, terminate this Agreement and Employee's employment, effective
thirty (30) days after written notice is provided to the other party. Should
Employee be terminated by Employer without good cause during the Term, Employer
shall deliver to Employee promptly a waiver and release agreement waiving and
releasing any claims Employee may have against Employer under the terms of this
Agreement in form reasonably satisfactory to Employer and Employee, and upon
Employee's execution thereof, Employee shall receive from Employer, in a
lump-sum payment due on the effective date of termination, the base salary at
the rate then in effect for whatever time period is remaining under the Term
(the Initial Term or the then current Renewal Term, as applicable) or for one
(1) year, whichever amount is greater (such period of time, the "Severance
Period"). If Employee resigns or otherwise terminates Employee's employment
without good reason pursuant to this Paragraph 6(d), Employee shall receive no
severance compensation.

         (e)      Change in Control of Employer. In the event of a "Change in
Control of Employer" (as defined below) during the Term, refer to Paragraph 13
below.

         Upon termination of his employment for any reason provided above,
Employee shall be entitled to receive all compensation earned and all benefits
and reimbursements due through the effective date of termination. Additional
compensation subsequent to termination, if any, will be due and payable to
Employee only to the extent and in the manner expressly provided above or in
Paragraph 13 hereof. All other rights and obligations of Employer and Employee
under this Agreement shall cease as of the effective date of termination, except
that Employer's obligations under Paragraph 10 hereof and Employee's obligations
under Paragraphs 4, 7, 8, 9, 11 and 18 hereof shall survive such termination in
accordance with their terms.

         If termination of Employee's employment arises out of Employer's
failure to pay Employee on a timely basis the amounts to which he is entitled
under this Agreement or as a result of any other

                                                                               6

<PAGE>

breach of this Agreement by Employer, as determined by a court of competent
jurisdiction or pursuant to the provisions of Paragraph 18 below, Employer shall
pay all amounts and damages to which Employee may be entitled as a result of
such breach, including interest thereon and all reasonable legal fees and
expenses and other costs incurred by Employee to enforce Employee's rights
hereunder.

         7.       Return of Company Property.

         All records, designs, patents, business plans, financial statements,
manuals, memoranda, lists and other property delivered to or compiled by
Employee by or on behalf of Employer, or its representatives, vendors or
customers which pertain to the business of Employer shall be and remain the
property of Employer, and be subject at all times to its discretion and control.
Likewise, all correspondence, reports, records, charts, advertising materials,
and other similar data pertaining to the business, activities or future plans of
Employer which is collected by Employee shall be delivered promptly to Employer
without request by it upon termination of Employee's employment.

         8.       Inventions.

         Employee shall disclose promptly to Employer any and all significant
conceptions and ideas for inventions, improvements and valuable discoveries,
whether patentable or not, which are conceived or made by Employee, solely or
jointly with another, during the period of employment or within one (1) year
hereafter, and which are directly related to the business or activities of
Employer and which Employee conceives as a result of Employee's employment by
Employer. Employee hereby assigns and agrees to assign all of Employee's
interests therein to Employer or its nominee. Whenever requested to do so by
Employer, Employee shall execute any and all applications, assignments or other
instruments that Employer shall deem necessary to apply for and obtain Letters
Patent of the United States or any foreign country or to otherwise protect
Employer's interest therein.

         9.       Trade Secrets.

         Employee agrees that he will not, during or after the Term of this
Agreement with Employer, disclose the specific terms of Employer's or its
subsidiaries' relationships or agreements with its significant vendors or
customers or any other significant and material trade secret of Employer or its
subsidiaries, whether in existence or proposed, to any person, firm,
partnership, corporation or business for any reason or purpose whatsoever other
than in the course of performing Employee's duties hereunder.

         10.      Indemnification.

         In the event Employee is made a party to any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative or
investigative (other than an action by Employer against Employee), by reason of
the fact that Employee is or was performing services under this Agreement, then
Employer shall indemnify Employee against all expenses (including attorneys'
fees), judgments, fines and amounts paid in settlement, as actually and
reasonably incurred by Employee in connection therewith except to the extent
that such expenses result from Employee's

                                                                               7

<PAGE>

gross, willful or wanton negligence or misconduct or fraud or criminal acts. In
the event that both Employee and Employer are made a party to the same
third-party action, complaint, suit or proceeding, Employer agrees to engage
competent legal representation, and Employee agrees to use the same
representation, provided that if counsel selected by Employer shall have a
conflict of interest that prevents such counsel from representing Employee,
Employee may engage separate counsel and Employer shall pay all attorneys' fees
of such separate counsel. Further, while Employee is expected at all times to
use Employee's best efforts to faithfully discharge his duties under this
Agreement, Employee cannot be held liable to Employer for errors or omissions
made in good faith where Employee has not exhibited gross, willful or wanton
negligence or misconduct or performed criminal and fraudulent acts that
materially damage the business of Employer.

         11.      No Prior Agreements.

         Employee hereby represents and warrants to Employer that the execution
of this Agreement by Employee and his employment by Employer and the performance
of Employee's duties hereunder will not violate or be a breach of any agreement
with a former employer, client or any other person or entity. Further, Employee
agrees to indemnify Employer for any claim, including but not limited to
attorneys' fees and expenses of investigation, by any such third party that such
third party may now have or may hereafter come to have against Employer based
upon or arising out of any noncompetition agreement, invention or secrecy
agreement between Employee and such third party which was in existence as of the
date of this Agreement.

         12.      Assignment; Binding Effect.

         Employee understands that Employer has selected him for employment on
the basis of Employee's personal qualifications, experience and skills.
Employee, therefore, shall not assign all or any portion of Employee's
performance under this Agreement, or any benefits received by Employee pursuant
to this Agreement except by will or the laws of descent.. Subject to the
preceding two sentences and the express provisions of Paragraph 13 below, this
Agreement shall be binding upon, inure to the benefit of and be enforceable by
the parties hereto and their respective heirs, legal representatives, successors
and assigns.

         13.      Change in Control.

         (a)      Employee understands and acknowledges that Employer may be
merged or consolidated with or into another entity and that such entity shall
automatically succeed to the rights and obligations of Employer hereunder or
that Employer may undergo another type of Change in Control. In the event such a
merger or consolidation or other Change in Control is initiated prior to the end
of the Term, then the provisions of this Paragraph 13 shall be applicable.

         (b)      In the event of a pending Change in Control wherein Employer
and Employee have not received written notice at least five (5) business days
prior to the anticipated closing date of the transaction giving rise to the
Change in Control from the successor to all or a substantial portion of
Employer's business and/or assets that such successor is willing as of the
closing to assume and agree to perform Employer's obligations under this
Agreement in the same manner and to the same extent

                                                                               8

<PAGE>

that Employer is hereby required to perform, then such Change in Control shall
be deemed to be a termination of this Agreement by Employer without good cause
during the Term, and (i) the noncompetition provision of Paragraph 4 shall not
apply; (ii) Employee shall receive from Employer, in a lump-sum payment due on
the effective date of such termination, an amount equal to three times the sum
of (A) the Employee's annual Base Salary and (B) the higher of (x) the highest
annual bonus paid to Employee under the Company's Annual Incentive Plan in
effect on the date hereof or a direct predecessor thereto or replacement thereof
for the past three fiscal years and (y) the Employee's annual bonus paid or
payable, including any bonus or portion thereof which has been earned but
deferred, under the Company's Annual Incentive Plan in effect on the date hereof
or a direct predecessor thereto or replacement thereof (and annualized for any
fiscal year during which the Employee was employed for less than 12 full
months), for the most recently completed or current fiscal year during the Term;
and (iii) until the third anniversary of the effective date of such termination,
Employee and, if applicable, Employee's dependents shall be eligible for
participation in and shall receive all benefits under welfare benefit plans,
practices, policies and programs provided by the Employer and its affiliated
companies (including, without limitation, medical, prescription, dental,
disability, employee life, group life, accidental death and travel accident
insurance plans and programs) (collectively, "Employer Welfare Programs") to the
extent applicable generally to other peer executives of Employer and its
affiliated companies at the same after-tax cost to Employee as if Employee was
employed by Employer, but in no event shall such Employer Welfare Programs
provide Employee with benefits that are less favorable, in the aggregate, than
the most favorable of such Employer Welfare Programs in effect for Employee at
any time during the 120-day period immediately preceding the date of such
termination; provided, however if Employer is unable to provide Employee and/or,
if applicable, any of Employee's dependents, with any benefits to which Employee
or such dependent is entitled pursuant to the terms of this Section 13(b)(iii)
under any of the Employer Welfare Programs, Employer shall at its cost provide
such benefit at a level no less favorable to Executive than would have been
provided under the Employer Welfare Programs under another plan or arrangement,
including an individual policy purchased by Employer for Employee or such
dependent(s). Employee agrees that if any benefit to be provided under the
Employer Welfare Programs is subject to the provisions of Part 6 of Subtitle B
of Title I of the Employee Retirement Income Security Act of 1974, as amended
("COBRA"), Employee shall make a timely COBRA election to continue such benefit
under COBRA during the applicable COBRA continuation period and Employer shall
reimburse Employee for the amount of the COBRA premiums, if any, required to be
paid by Employee for such coverage.

         (c)      Employee will be given sufficient time and opportunity to
elect whether to exercise all or any of Employee's vested options to purchase
Employer Common Stock, including any options with accelerated vesting under the
provisions of Employer's 1997 Stock Option Plan, or any other Employer stock
incentive plan, such that Employee may convert the options to shares of Employer
Common Stock at or prior to the closing of the transaction giving rise to the
Change in Control, if Employee so desires.

         (d)      In the event that a successor in a pending Change in Control
gives notice pursuant to Paragraph 13(b) that it will assume Employer's
obligations under this Agreement and at the time of or within twelve (12) months
following such Change in Control Employee either (i) terminates this Agreement
for good reason (as defined in Paragraph 6(c) of this Agreement) or (ii) is

Employer other than for good cause (as defined in Paragraph 6(c) of this
Agreement), then effective as of the date of such termination, (A) the
noncompetition provisions of Paragraph 4 shall no longer apply, (B) Employee
shall receive from Employer, in a lump-sum payment due on the effective date of
such termination, an amount equal to three times the sum of (1) the Employee's
annual Base Salary and (2) the higher of (x) the highest annual bonus paid to
Employee under the Company's Annual Incentive Plan in effect on the date hereof
or a direct predecessor thereto or replacement thereof, for the past three
fiscal years and (y) the Employee's annual bonus paid or payable, including any
bonus or portion thereof which has been earned but deferred, under the Company's
Annual Incentive Plan in effect on the date hereof or a direct predecessor
thereto or replacement thereof (and annualized for any fiscal year during which
the Employee was employed for less than 12 full months), for the most recently
completed or current fiscal year during the Term and (C) until the third
anniversary of the effective date of such termination, Employee and, if
applicable, Employee's dependents shall be eligible for participation in and
shall receive all benefits under welfare benefit plans, practices, policies and
programs provided by the Employer and its affiliated companies (including,
without limitation, medical, prescription, dental, disability, employee life,
group life, accidental death and travel accident insurance plans and programs)
(collectively, "Employer Welfare Programs") to the extent applicable generally
to other peer executives of Employer and its affiliated companies at the same
after-tax cost to Employee as if Employee was employed by Employer, but in no
event shall such Employer Welfare Programs provide Employee with benefits that
are less favorable, in the aggregate, than the most favorable of such Employer
Welfare Programs in effect for Employee at any time during the 120-day period
immediately preceding the date of such termination; provided, however if
Employer is unable to provide Employee and/or, if applicable, any of Employee's
dependents, with any benefits to which Employee or such dependent is entitled
pursuant to the terms of this Section 13(b)(iii) under any of the Employer
Welfare Programs, Employer shall at its cost provide such benefit at a level no
less favorable to Executive than would have been provided under the Employer
Welfare Programs under another plan or arrangement, including an individual
policy purchased by Employer for Employee or such dependent(s). Employee agrees
that if any benefit to be provided under the Employer Welfare Programs is
subject to the provisions of Part 6 of Subtitle B of Title I of the Employee
Retirement Income Security Act of 1974, as amended ("COBRA"), Employee shall
make a timely COBRA election to continue such benefit under COBRA during the
applicable COBRA continuation period and Employer shall reimburse Employee for
the amount of the COBRA premiums, if any, required to be paid by Employee for
such coverage.

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

                  (i)      any person or entity, other than Employer or an
                           employee benefit plan of Employer, acquires directly
                           or indirectly the Beneficial Ownership (as defined in
                           Section 13(d) of the Securities Exchange Act of 1934,
                           as amended) of any voting security of Employer and
                           immediately after such acquisition such person or
                           entity is, directly or indirectly, the Beneficial
                           Owner of voting securities representing 50% or more
                           of the total voting power of all of the
                           then-outstanding voting securities of Employer;

                                                                              10

                           individuals who, as of the date hereof, constitute
                           the Board (the "Current Directors"); (B) the
                           individuals who thereafter are elected to the Board
                           and whose election, or nomination of election, to the
                           to the Board was approved by a vote of at least
                           two-thirds (2/3) of the Current Directors then still
                           in office (such directors becoming "Additional
                           Current Directors" immediately following their
                           election); and (C) the individuals who are elected to
                           the Board and whose election, or nomination for
                           election, to the Board was approved by a vote of at
                           least two-thirds (2/3) of the Current Directors and
                           Additional Current Directors then still in office
                           (such directors also becoming "Additional Current
                           Directors" immediately following their election); or

                  (iii)    the stockholders of Employer shall approve an
                           agreement for the sale or disposition by Employer of
                           all or a substantial portion of Employer's assets
                           (i.e., 50% or more of the total assets of Employer).

all excise taxes that Employee incurs under Section 4999 of the Internal Revenue
Code of 1986, as amended, as a result of any Change in Control, such amount
determined by Employer or by an accounting firm chosen by Employer. In addition,

accompanied by a copy of Employee's tax return(s) as filed reflecting the excise
tax paid by Employee; provided however, if Employee's tax return reflects an
excise tax amount that is less than the amount determined by the Employer or its
accounting firm pursuant to this paragraph (g), the Employer shall be required
to reimburse Employee in an amount equal to such lesser amount. In addition, if
at any time the Employee receives a refund from all the Internal Revenue Service
of all or any portion of the amount of the excise tax or federal, state or local
income taxes described in this paragraph (g) that were paid to Employee by
Employer, Employee shall pay Employer the amount of the refund with in ten (10)
days of Employee's receipt of such refund. The amount reimbursed by Employer
hereunder shall not be subject to offset or reduction for any amount owed or
claimed to be owed to Employer or its successor by Employee. If not paid within
ten (10) days from date of demand, the amount due under this subsection shall
bear interest at the maximum non-usurious rate allowed by law from the date of
demand to the date of payment.
