                            2001 STOCK INCENTIVE PLAN

         1. AMENDMENT AND RESTATEMENT. The Quanta Services, Inc. Amended and
Restated 1997 Stock Option Plan is amended and restated as set forth herein as
the "Quanta Services, Inc. 2001 Stock Incentive Plan", effective as of

effect with respect to such Options prior to the Effective Date and Options
granted after the Effective Date shall be subject to the terms and conditions of
the Plan as set forth herein, as it may be amended from time to time.

         2. PURPOSE. The purposes of the Plan are to attract and retain for the
Company and its Affiliates the best available personnel, to provide additional
incentive to Employees, Directors and Consultants and to increase their interest
in the Company's welfare, and to promote the success of the business of the
Company and its Affiliates.

Company's financial statements.

Non-Employee Directors, in accordance with Rule 16b-3, as necessary in each case
to satisfy such requirements with respect to Awards granted under the Plan.
Within the scope of such authority, the Committee may (i) delegate to a
committee of one or more members of the Board who are not Outside Directors the
authority to grant Options to eligible persons who are either (A) not then
Covered Employees and are not expected to be Covered Employees at the time of
recognition of income resulting from such Options or (B) not persons with
respect to whom the Company wishes to comply with Section 162(m) of the Code
and/or (ii) delegate to a committee of one or more members of the Board who are
not Non-Employee Directors the authority to grant Options to eligible persons
who are not then subject to Section 16 of the Exchange Act. Notwithstanding the
foregoing provisions, the Chief Executive Officer has the authority to grant
Non-Qualified Stock Options to certain Employees, as described in Section 6 of
this Plan.

         (h) "Common Stock" means the Common Stock, $0.0001 par value per share,
of the Company or the common stock that the Company may in the future be
authorized to issue (as long as the common stock varies from that currently
authorized, if at all, only in amount of par value).

         (i) "Company" means Quanta Services, Inc., a Delaware corporation.

         (j) "Consultant" means any person (other than an Employee or a

or Form S-8 promulgated under the Securities Act.

Agreement, service shall not be considered interrupted or terminated for this
purpose in the case of (i) any approved leave of absence, (ii) transfers among
the Company, any Affiliate, or any successor, in any capacity of Employee,
Director or Consultant, or (iii) any change in status as long as the individual
remains in the service of the Company or an Affiliate in any capacity of
Employee, Director or Consultant. An approved leave of absence shall include
sick leave, military leave, or any other authorized personal leave. For purposes
of each Incentive Stock Option, if such leave exceeds ninety (90) days, and
re-employment upon expiration of such leave is not guaranteed by statute or
contract,

such ninety (90)-day period.

         (l) "Covered Employee" means the Chief Executive Officer and the four

an Affiliate.

         (n) "Disability" means the "disability" of a person as defined in a
then effective long-term disability plan maintained by the Company that covers
such person, or if such a plan does not exist at any relevant time, "Disability"
means the permanent and total disability of a person within the meaning of
Section 22(e)(3) of the Code. For purposes of determining the time during which
an Incentive Stock Option may be exercised under the terms of an Option
Agreement, "Disability" means the permanent and total disability of a person
within the meaning of Section 22(e)(3) of the Code. Section 22(e)(3) of the Code
provides that an individual is totally and permanently disabled if he is unable
to engage in any substantial gainful activity by reason of any medically
determinable physical or mental impairment which can be expected to result in
death or which has lasted or can be expected to last for a continuous period of
not less than twelve (12) months.

         (o) "Employee" means any person, including an Officer or Director, who
is employed, within the meaning of Section 3401 of the Code, by the Company or
an Affiliate. The provision of compensation by the Company or an Affiliate to a
Director solely with respect to such individual rendering services in the
capacity of a Director, however, shall not be sufficient to constitute
"employment" by the Company or that Affiliate.

         (p) "Exchange Act" means the Securities Exchange Act of 1934, as
amended, and any successor statute. Reference in the Plan to any section of the
Exchange Act shall be deemed to include any amendments or successor provisions
to such section and any rules and regulations relating to such section.

         (q) "Fair Market Value" means, as of any date, the value of the Common
Stock determined as follows:

                  (i) If the Common Stock is listed on any established stock
         exchange or traded on the Nasdaq National Market or the Nasdaq SmallCap
         Market, the Fair Market Value of a share of Common Stock shall be the
         closing sales price for such a share of Common Stock (or the closing
         bid, if no sales were reported) as quoted on such exchange or market
         (or the exchange or market with the greatest volume of trading in the
         Common Stock) on the day of determination (or if no such price or bid
         is reported on that day, on last market trading day prior to the day of
         determination), as reported in The Wall Street Journal or such other
         source as the Committee deems reliable.

                  (ii) In the absence of any such established markets for the
         Common Stock, the Fair Market Value shall be determined in good faith
         by the Committee.

<PAGE>   6

         5. SHARES SUBJECT TO PLAN. Subject to adjustment pursuant to Section
11(a) hereof, the total amount of Common Stock with respect to which Awards may
be granted under the Plan shall not exceed the greater of (i) 3,571,275 shares
and (ii) 15 percent of the total number of shares of Stock, determined at the
time of a particular Award, outstanding or reserved for issuance upon the

share from time to time. Notwithstanding the foregoing, the total amount of
Common Stock with respect to which Incentive Stock Options may be granted under
the Plan shall not exceed 3,571,275 shares (subject to adjustment pursuant to
Section 11(a) hereof. Any shares of Common Stock covered by an Award (or a
portion of an Award) that is forfeited or canceled, or that expires shall be
deemed not to have been issued for purposes of determining the maximum aggregate
number of shares of Common Stock which may be issued under the Plan and shall
again be available for Awards under the Plan. At all times during the term of
the Plan, the Company shall reserve and keep available such number of shares of
Common Stock as will be required to satisfy the requirements of outstanding
Awards under the Plan. Nothing in this Section 5 shall impair the right of the
Company to reduce the number of outstanding shares of Common Stock pursuant to
repurchases, redemptions, or otherwise; provided, however, that no reduction in
the number of outstanding shares of Common Stock shall (a) impair the validity
of any outstanding Award, whether or not that Award is fully exercisable or
fully vested, or (b) impair the status of any shares of Common Stock previously
issued pursuant to an Award as duly authorized, validly issued, fully paid, and
nonassessable. The shares to be delivered under the Plan shall be made available
from (a) authorized but unissued shares of Common Stock, (b) Common Stock held
in the treasury of the Company, or (c) previously issued shares of Common Stock
reacquired by the Company, including shares purchased on the open market, in
each situation as the Committee may determine from time to time in its sole
discretion.

         6. ELIGIBILITY. Awards other than Incentive Stock Options may be
granted to Employees, Officers, Directors, and Consultants. Incentive Stock
Options may be granted only to Employees (including Officers and Directors who
are also Employees), as limited by clause (iii) of Section 3(a). The Committee
in its sole discretion shall select the recipients of Awards; provided, however,
that the Chief Executive Officer in his sole discretion may select the
recipients of Non-Qualified Stock Options if (i) such recipients are not
Officers, (ii) the aggregate number of shares of Common Stock subject to such
Options does not exceed 100,000 shares in any one calendar quarter, and (iii) no
individual may be granted an Option in any one calendar quarter to purchase more
than 20,000 shares of Common Stock. A Grantee may be granted more than one Award
under the Plan, and Awards may be granted at any time or times during the term
of the Plan. The grant of an Award to an Employee, Officer, Director or
Consultant shall not be deemed either to entitle that individual to, or to
disqualify that individual from, participation in any other grant of Awards
under the Plan.

         7. LIMITATION ON INDIVIDUAL AWARDS. Subject to the provisions of
Section 11(a), the maximum number of shares of Common Stock that may be subject
to Awards granted to any one person under the Plan shall not exceed 1,500,000
shares of Common Stock. The limitation set forth in the preceding sentence shall
be applied in a manner which will permit compensation generated under the Plan
to constitute "performance-based" compensation for purposes of Section 162(m) of
the Code, including counting against such maximum number of shares, to the
extent required under Section 162(m) of the Code and applicable interpretive

authority thereunder, any shares of Common Stock subject to Options that are
canceled or repriced.

         8. TERMS AND CONDITIONS OF OPTIONS. The Committee, and if applicable
pursuant to Section 6, the Chief Executive Officer, shall determine (a) whether
each Option shall be granted as an Incentive Stock Option or a Non-Qualified
Stock Option and (b) the provisions, terms and conditions of each Option
including, but not limited to, the vesting schedule, the number of shares of
Common Stock subject to the Option, the exercise price of the Option, the period
during which the Option may be exercised, repurchase provisions, forfeiture
provisions, methods of payment, and all other terms and conditions of the
Option, subject to the following:

         (a) Form of Option Grant. Each Option granted under the Plan shall be
evidenced by a written Option Agreement in such form (which need not be the same
for each Optionee) as the Committee, or if applicable the Chief Executive
Officer, from time to time approves, but which is not inconsistent with the
Plan, including any provisions that may be necessary to assure that any Option
that is intended to be an Incentive Stock Option will comply with Section 422 of
the Code.

         (b) Date of Grant. The date of grant of an Option will be the date on
which the Committee, or if applicable the Chief Executive Officer, makes the
determination to grant such Option unless otherwise specified by the Committee.
The Option Agreement evidencing the Option will be delivered to the Optionee
with a copy of the Plan and other relevant Option documents, within a reasonable
time after the date of grant.

         (c) Exercise Price. The exercise price of a Non-Qualified Stock Option
shall be not less than 85% of the Fair Market Value of the shares of Common
Stock on the date of grant of the Option. The exercise price of any Incentive
Stock Option shall be not less than 100% of the Fair Market Value of the shares
of Common Stock on the date of grant of the Option. The exercise price of any
Incentive Stock Option granted to a Ten Percent Shareholder shall not be less
than 110% of the Fair Market Value of the shares of Common Stock on the date of
grant of the Option.

         (d) Exercise Period. Options shall be exercisable within the time or
times or upon the event or events determined by the Committee and set forth in
the Option Agreement; provided, however, that no Option shall be exercisable
after the expiration of ten (10) years from the date of grant of the Option, and
provided further, that no Incentive Stock Option granted to a Ten Percent
Shareholder shall be exercisable after the expiration of five (5) years from the
date of grant of the Option.

         (e) Limitations on Incentive Stock Options. The aggregate Fair Market
Value (determined as of the date of grant of an Option) of Common Stock which
any Employee is first eligible to purchase during any calendar year by exercise
of Incentive Stock Options granted under the Plan and by exercise of incentive
stock options (within the meaning of Section 422 of the Code) granted under any
other incentive stock option plan of the Company or an Affiliate shall not
exceed $100,000. If the Fair Market Value of stock with respect to which all
incentive

<PAGE>   8

stock options described in the preceding sentence held by any one Optionee are
exercisable for the first time by such Optionee during any calendar year exceeds
$100,000, the Options (that are intended to be Incentive Stock Options on the
date of grant thereof) for the first $100,000 worth of shares of Common Stock to
become exercisable in such year shall be deemed to constitute incentive stock
options within the meaning of Section 422 of the Code and the Options (that are
intended to be Incentive Stock Options on the date of grant thereof) for the
shares of Common Stock in the amount in excess of $100,000 that become
exercisable in that calendar year shall be treated as Non-Qualified Stock
Options. If the Code or the Treasury regulations promulgated thereunder are
amended after the effective date of the Plan to provide for a different limit
than the one described in this Section 8(e), such different limit shall be
incorporated herein and shall apply to any Options granted after the effective
date of such amendment.

         (f) Transferability of Options. Options granted under the Plan, and any
interest therein, shall not be transferable or assignable by the Optionee, and
may not be made subject to execution, attachment or similar process, otherwise
than by will or by the laws of descent and distribution, and shall be
exercisable during the lifetime of the Optionee only by the Optionee; provided,
that the Optionee may, however, designate persons who or which may exercise his
Options following his death. Notwithstanding the preceding sentence,
Non-Qualified Stock Options may be transferred to such family members, family
member trusts and charitable institutions as the Committee, in its sole
discretion, may provide for at the date of the grant of such Option in the
Optionee's Option Agreement.

         (g) Acquisitions and Other Transactions. The Committee may, from time
to time, assume outstanding options granted by another entity, whether in
connection with an acquisition of such other entity or otherwise, by either (i)
granting an Option under the Plan in replacement of or in substitution for the
option assumed by the Company, or (ii) treating the assumed option as if it had
been granted under the Plan if the terms of such assumed option could be applied
to an Option granted under the Plan. Such assumption shall be permissible if the
holder of the assumed option would have been eligible to be granted an Option
hereunder if the other entity had applied the rules of this Plan to such grant.
The Committee also may grant Options under the Plan in settlement of or
substitution for, outstanding options or obligations to grant future options in
connection with the Company or an Affiliate acquiring another entity, an
interest in another entity or an additional interest in an Affiliate whether by
merger, stock purchase, asset purchase or other form of transaction.
Notwithstanding the foregoing provisions of this Section 8, in the case of an
Option issued or assumed pursuant to this Section 8(g), the exercise price for
the Option shall be determined in accordance with the principles of Section
424(a) of the Code and the Treasury regulations promulgated thereunder.

         (h) Grants of Options to Non-Employee Directors. In addition to any
other Non-Qualified Stock Options that the Committee may in its discretion grant
to Non-Employee Directors, each individual who is elected or appointed to become
a new, first-time Non-Employee Director during the term of the Plan and agrees
to become a Non-Employee Director as a result of such election or appointment
shall receive, without the exercise of the discretion of any person, a
Non-Qualified Stock Option to purchase 15,000 shares of Common Stock on the
effective date of such election or appointment (subject to adjustment pursuant
to Section 11(a) hereof). In addition, on the day after each annual meeting of
the Company's stockholders, each

<PAGE>   9

person who is a continuing Non-Employee Director on any such date and who has
been a Non-Employee Director for at least six months as of such date shall
receive, without the exercise of the discretion of any person, a Non-Qualified
Stock Option to purchase of 7,500 shares of Common Stock (subject to adjustment
pursuant to Section 11(a) hereof). In the event that there are not sufficient
shares available under the Plan to allow for the grant to each Non-Employee
Director of a Non-Qualified Stock Option for the number of shares provided for
in this Section 8(h), each Non-Employee Director shall receive a Non-Qualified
Stock Option for his pro rata share of the total number of shares of Common
Stock available under the Plan. The exercise price of each share of Common Stock
subject to an Option granted to a Non-Employee Director shall equal the Fair
Market Value of a share of Common Stock on the date such Option is granted. Each
Option granted to a Non-Employee Director shall become exercisable six months
from, the date the Grantee becomes a Non-Employee Director and shall have a term
of ten (10) years from the date the Option is granted. Notwithstanding the
exercise period of any Option granted to a Non-Employee Director, all such
Options shall immediately become exercisable upon (i) the death of a
Non-Employee Director while serving as such or (ii) a Change in Control.

         9. EXERCISE OF OPTIONS.

         (a) Notice. Options may be exercised only by delivery to the Company of
a written exercise agreement approved by the Committee (which need not be the
same for each Optionee), stating the number of shares of Common Stock being
purchased, the restrictions imposed on the shares of Common Stock, if any, and
such representations and agreements regarding the Optionee's investment intent
and access to information and other matters, if any, as may be required by the
Company to comply with applicable securities laws, or as may be deemed
appropriate by the Company in connection with the issuance of shares of Common
Stock upon exercise of the Option, together with payment in full of the exercise
price for the number of shares of Common Stock being purchased. Such exercise
agreement may be part of an Optionee's Option Agreement.

         (b) Early Exercise. An Option Agreement may, but need not, include a
provision that permits the Optionee to elect at any time while an Employee,
Director or Consultant, to exercise any part or all of the Option prior to full
vesting of the Option. Any unvested shares of Common Stock received pursuant to
such exercise may be subject to a repurchase right in favor of the Company or an
Affiliate or to any other restriction the Committee, or if applicable the Chief
Executive Officer, determines to be appropriate

         (c) Payment. Payment for the shares of Common Stock to be purchased
upon exercise of an Option may be made in cash (by check) or, where approved by
the Committee in its sole discretion at the date of grant and stated in the
Option Agreement and where permitted by law: (i) if a public market for the
Common Stock exists, through a "same day sale" commitment from the Optionee and
a broker-dealer that is a member of the National Association of Securities
Dealers, Inc. (an "NASD Dealer") whereby the Optionee irrevocably elects to
exercise the Option and to sell a portion of the shares of Common Stock so
purchased to pay for the exercise price and whereby the NASD Dealer irrevocably
commits upon receipt of such shares of Common Stock to forward the exercise
price directly to the Company; (ii) if a public market for the Common Stock
exists, through a "margin" commitment from the Optionee and an NASD

Dealer whereby the Optionee irrevocably elects to exercise the Option and to
pledge the shares of Common Stock so purchase to the NASD Dealer in a margin
account as security for a loan from the NASD Dealer in the amount of the
exercise price, and whereby the NASD Dealer irrevocably commits upon receipt of
such shares of Common Stock to forward the exercise price directly to the
Company; (iii) by surrender for cancellation of Qualifying Shares at the Fair
Market Value per share at the time of exercise (provided that such surrender
does not result in an accounting charge for the Company); (iv) by delivery of
the Optionee's promissory note with such recourse, interest, security,
redemption and other provisions as the Committee may require; or (v) by any
combination of the foregoing. No shares of Common Stock may be issued until full
payment of the purchase price therefor has been made.

         (d) Withholding Taxes. The Committee may establish such rules and
procedures as it considers desirable in order to satisfy any obligation of the
Company to withhold the statutory prescribed minimum amount of federal or state
income taxes or other taxes with respect to the exercise of any Option granted
under the Plan. Prior to issuance of the shares of Common Stock upon exercise of
an Option, the Optionee shall pay or make adequate provision acceptable to the
Committee for the satisfaction of the statutory minimum prescribed amount of any
federal or state income or other tax withholding obligations of the Company, if
applicable. Upon exercise of an Option, the Company shall withhold or collect
from the Optionee an amount sufficient to satisfy such tax withholding
obligations.

         (e) Exercise of Option Following Termination of Continuous Service.

                  (i) An Option may not be exercised after the expiration date
         of such Option set forth in the Option Agreement and may be exercised
         following the termination of an Optionee's Continuous Service only to
         the extent provided in the Option Agreement.

                  (ii) Where the Option Agreement permits an Optionee to
         exercise an Option following the termination of the Optionee's
         Continuous Service for a specified period, the Option shall terminate
         to the extent not exercised on the last day of the specified period or
         the last day of the original term of the Option, whichever occurs
         first.

                  (iii) Any Option designated as an Incentive Stock Option, to
         the extent not exercised within the time permitted by law for the
         exercise of Incentive Stock Options following the termination of an
         Optionee's Continuous Service, shall convert automatically to a
         Non-Qualified Stock Option and thereafter shall be exercisable as such
         to the extent exercisable by its terms for the period specified in the
         Option Agreement.

                  (iv) The Committee shall have discretion to determine whether
         the Continuous Service of an Optionee has terminated and the effective
         date on which such Continuous Service terminates and whether the
         Optionee's Continuous Service terminated as a result of the Disability
         of the Optionee.

         (f) Limitations on Exercise.

                  (i) The Committee, or if applicable the Chief Executive
         Officer, may specify a reasonable minimum number of shares of Common
         Stock or a percentage of the shares subject to an Option that may be
         purchased on any exercise of an Option; provided, that such minimum
         number will not prevent Optionee from exercising the full number of
         shares of Common Stock as to which the Option is then exercisable.

                  (ii) The obligation of the Company to issue any shares of
         Common Stock pursuant to the exercise of any Option shall be subject to
         the condition that such exercise and the issuance and delivery of such
         shares pursuant thereto comply with the Securities Act, all applicable
         state securities laws and the requirements of any stock exchange or
         national market system upon which the shares of Common Stock may then
         be listed or quoted, as in effect on the date of exercise. The Company
         shall be under no obligation to register the shares of Common Stock
         with the Securities and Exchange Commission or to effect compliance
         with the registration, qualification or listing requirements of any
         state securities laws or stock exchange or national market system, and
         the Company shall have no liability for any inability or failure to do
         so.

                  (iii) As a condition to the exercise of an Option, the Company
         may require the person exercising such Option to represent and warrant
         at the time of any such exercise that the shares of Common Stock are
         being purchased only for investment and without any present intention
         to sell or distribute such shares of Common Stock if, in the opinion of
         counsel for the Company, such a representation is required by any
         securities or other applicable laws.

         (g) Modification, Extension And Renewal of Options . The Committee
shall have the power to modify, extend or renew outstanding Options and to
authorize the grant of new Options in substitution therefor, provided that
(except as permitted by Section 11 of this Plan) any such action may not,
without the written consent of any Optionee, impair any rights under any Option
previously granted to such Optionee. Any outstanding Incentive Stock Option that
is modified, extended, renewed or otherwise altered will be treated in
accordance with Section 424(h) of the Code.

         (h) Privileges of Stock Ownership. No Optionee will have any of the
rights of a shareholder with respect to any shares of Common Stock subject to an
Option until such Option is properly exercised and the purchased shares are
issued and delivered to the Optionee, as evidenced by an appropriate entry on
the books of the Company or of a duly authorized transfer agent of the Company.
No adjustment shall be made for dividends or distributions or other rights for
which the record date is prior to such date of issuance and delivery, except as
provided in the Plan.

         10. TERMS AND CONDITIONS OF RESTRICTED STOCK AWARDS. Each Restricted
Stock Agreement shall be in such form and shall contain such terms and
conditions as the Committee shall deem appropriate. The terms and conditions of
such Restricted Stock Agreements may change from time to time, and the terms and
conditions of separate Restricted

Quanta Services, Inc.

<PAGE>   12

Stock Agreements need not be identical, but each such Restricted Stock Agreement
shall be subject to the terms and conditions of this Section 10.

         (a) Forfeiture Restrictions. Shares of Common Stock that are the
subject of a Restricted Stock Award shall be subject to restrictions on
disposition by the Grantee and to an obligation of the Grantee to forfeit and
surrender the shares to the Company under certain circumstances (the "Forfeiture
Restrictions"). The Forfeiture Restrictions shall be determined by the Committee
in its sole discretion, and the Committee may provide that the Forfeiture
Restrictions shall lapse on the passage of time, the attainment of one or more
performance targets established by the Committee, or the occurrence of such
other event or events determined to be appropriate by the Committee. The
Forfeiture Restrictions applicable to a particular Restricted Stock Award (which
may differ from any other such Restricted Stock Award) shall be stated in the
Restricted Stock Agreement.

         (b) Restricted Stock Awards. At the time any Restricted Stock Award is
granted under the Plan, the Company and the Grantee shall enter into a
Restricted Stock Agreement setting forth each of the matters addressed in this
Section 10 and such other matters as the Committee may determine to be
appropriate. Shares of Common Stock awarded pursuant to a Restricted Stock Award
shall be represented by a stock certificate registered in the name of the
Grantee of such Restricted Stock Award. The Grantee shall have the right to
receive dividends with respect to the shares of Common Stock subject to a
Restricted Stock Award, to vote the shares of Common Stock subject thereto and
to enjoy all other stockholder rights with respect to the shares of Common Stock
subject thereto, except that, unless provided otherwise in the Restricted Stock
Agreement, (i) the Grantee shall not be entitled to delivery of the shares of
Common Stock certificate until the Forfeiture Restrictions have expired, (ii)
the Company or an escrow agent shall retain custody of the shares of Common
Stock until the Forfeiture Restrictions have expired, (iii) the Grantee may not
sell, transfer, pledge, exchange, hypothecate or otherwise dispose of the shares
of Common Stock until the Forfeiture Restrictions have expired, and (iv) a
breach of the terms and conditions established by the Committee pursuant to the
Restricted Stock Agreement shall cause a forfeiture of the Restricted Stock
Award. At the time of such Award, the Committee may, in its sole discretion,
prescribe additional terms, conditions or restrictions relating to Restricted
Stock Award, including rules pertaining to the termination of the Grantee's
Continuous Service (by retirement, Disability, death or otherwise) prior to
expiration of the Forfeiture Restrictions. Such additional terms, conditions or
restrictions shall also be set forth in a Restricted Stock Agreement made in
connection with the Restricted Stock Award.

         (c) Rights and Obligations of Grantee. One or more stock certificates
representing shares of Common Stock, free of Forfeiture Restrictions, shall be
delivered to the Grantee promptly after, and only after, the Forfeiture
Restrictions have expired. Each Restricted Stock Agreement shall require that
(i) the Grantee, by his or her acceptance of the Restricted Stock Award, shall
irrevocably grant to the Company a power of attorney to transfer any shares so
forfeited to the Company and agrees to execute any documents requested by the
Company in connection with such forfeiture and transfer, and (ii) such
provisions regarding transfers of forfeited shares of Common Stock shall be
specifically performable by the Company in a court of equity or law.

<PAGE>   13

         (d) Restriction Period. The Restriction Period for a Restricted Stock
Award shall commence on the date of grant of the Restricted Stock Award and,
unless otherwise established by the Committee and stated in the Restricted Stock
Award Agreement, shall expire upon satisfaction of the conditions set forth in
the Restricted Stock Agreement pursuant to which the Forfeiture Restrictions
will lapse.

         (e) Securities Restrictions. The Committee may impose other conditions
on any shares of Common Stock subject to a Restricted Stock Award as it may deem
advisable, including (i) restrictions under applicable state or federal
securities laws, and (ii) the requirements of any stock exchange or national
market system upon which shares of Common Stock are then listed or quoted.

         (f) Payment for Restricted Stock. The Committee shall determine the
amount and form of any payment for shares of Common Stock received pursuant to a
Restricted Stock Award; provided, that in the absence of such a determination,
the Grantee shall not be required to make any payment for shares of Common Stock
received pursuant to a Restricted Stock Award, except to the extent otherwise
required by law.

         (g) Forfeiture of Restricted Stock. Subject to the provisions of the
particular Restricted Stock Agreement, on termination of the Grantee's
Continuous Service during the Restriction Period, the shares of Common Stock
subject to the Restricted Stock Award shall be forfeited by the Grantee. Upon
any forfeiture, all rights of the Grantee with respect to the forfeited shares
of the Common Stock subject to the Restricted Stock Award shall cease and
terminate, without any further obligation on the part of the Company, except
that if so provided in the Restricted Stock Agreement applicable to the
Restricted Stock Award, the Company shall repurchase each of the shares of
Common Stock forfeited for the purchase price per share paid by the Grantee. The
Committee will have discretion to determine whether the Continuous Service of a
Grantee has terminated and the date on which such Continuous Service terminates
and whether the Grantee's Continuous Service terminated as a result of the
Disability of the Grantee.

         (h) Lapse of Forfeiture Restrictions in Certain Events; Committee's
Discretion. Notwithstanding the provisions of Section 10(g) or any other
provision in the Plan to the contrary, the Committee may, in its discretion and
as of a date determined by the Committee, fully vest any or all Common Stock
awarded to the Grantee pursuant to a Restricted Stock Award, and upon such
vesting, all Forfeiture Restrictions applicable to such Restricted Stock Award
shall lapse or terminate. Any action by the Committee pursuant to this Section
10(h) may vary among individual Grantees and may vary among the Restricted Stock
Awards held by any individual Grantee. Notwithstanding the preceding provisions
of this Section 10(h), the Committee may not take any action described in this
Section 10(h) with respect to a Restricted Stock Award that has been granted to
a Covered Employee if such Award has been designed to meet the exception for
performance-based compensation under Section 162(m) of the Code.

         11. ADJUSTMENT UPON CHANGES IN CAPITALIZATION AND CORPORATE EVENTS.

         (a) Capital Adjustments. The number of shares of Common Stock (i)
covered by each outstanding Award granted under the Plan, the exercise or
purchase price of such outstanding Award, and any other terms of the Award that
the Committee determines requires adjustment and (ii) available for issuance
under Sections 5, 7 and 8(h) shall be adjusted to reflect, as deemed appropriate
by the Committee, any increase or decrease in the number of shares of Common
Stock resulting from a stock dividend, stock split, reverse stock split,
combination, reclassification or similar change in the capital structure of the
Company without receipt of consideration, subject to any required action by the
Board or the shareholders of the Company and compliance with applicable
securities laws; provided, however, that a fractional share will not be issued
upon exercise of any Award, and either (i) any fraction of a share of Common
Stock that would have resulted will be cashed out at Fair Market Value or (ii)
the number of shares of Common Stock issuable under the Award will be rounded up
to the nearest whole number, as determined by the Committee. Except as the
Committee determines, no issuance by the Company of shares of capital stock of
any class, or securities convertible into shares of capital stock of any class,
shall affect, and no adjustment by reason hereof shall be made with respect to,
the number or price of shares of Common Stock subject to an Award.

         (b) Dissolution or Liquidation. The Committee shall notify the Grantee
at least twenty (20) days prior to any proposed dissolution or liquidation of
the Company. Unless provided otherwise in an individual Option Agreement or
Restricted Stock Agreement or in a then-effective written employment agreement
between the Grantee and the Company or an Affiliate, to the extent that an Award
has not been previously exercised, the Company's repurchase rights relating to
an Award have not expired or the Forfeiture Restrictions have not lapsed, any
such Award that is an Option shall expire and any such Award that is a
Restricted Stock Award shall be forfeited and the shares of Common Stock subject
to such Award shall be returned to the Company, in each case, immediately prior
to consummation of such dissolution or liquidation, such Award shall terminate
immediately prior to consummation of such dissolution or liquidation.

         (c) Change in Control. If, during the effectiveness of the Plan (i) any
"person" (as such term is used in Sections 13(d) and 14(d) of the Exchange Act)
is or becomes the "beneficial owner" (as defined in Rule 13d-3 under the
Exchange Act), directly or indirectly, of securities of the Company representing
50 percent or more of the combined voting power of the Company's then
outstanding securities; (ii) as a result of, or in connection with, any tender
offer or exchange offer, merger, or other business combination (a
"Transaction"), the persons who were directors of the Company immediately before
the Transaction shall cease to constitute a majority of the Board of Directors
of the Company or any successor to the Company; (iii) the Company is merged or
consolidated with another corporation and as a result of the merger or
consolidation less than 75 percent of the outstanding voting securities of the
surviving or resulting corporation shall then be owned in the aggregate by the
former stockholders of the Company; (iv) a tender offer or exchange offer is
made and consummated for the ownership of securities of the Company representing
50 percent or more of the combined voting power of the Company's then
outstanding voting securities; or (v) the Company transfers substantially all of
its assets to another corporation which is not controlled by the Company (any
such event described in this Section 11(c), a "Change in Control"), (A) each
Option which is at the time outstanding under the Plan shall (1) except as
provided otherwise in an individual Option Agreement, automatically

<PAGE>   15

become, subject to all other terms of the Option Agreement, fully vested and
exercisable and be released from any repurchase or forfeiture rights,
immediately prior to the specified effective date of such Change in Control, for
all of the shares of Common Stock at the time represented by such Option, and
(2) notwithstanding any contrary terms in the Option Agreement (other than terms
providing for a specific exercise period following a Change in Control), expire
twenty (20) days after the Committee gives written notice to Optionees
specifying the terms and conditions of the acceleration of the Options, except
as provided otherwise in a then-effective written employment agreement between
the Grantee and the Company or an Affiliate or as provided otherwise
specifically with respect to a Change in Control in an individual Option
Agreement and (B) the Forfeiture Restrictions applicable to all outstanding
Restricted Stock Awards shall lapse and shares of Common Stock subject to such
Restricted Stock Awards shall be released from escrow, if applicable, and
delivered to the Grantees of the Awards free of any Forfeiture Restriction.

         To the extent that an Optionee exercises his Option before or on the
effective date of the Change in Control, the Company shall issue all Common
Stock purchased by exercise of that Option, and those shares of Common Stock
shall be treated as issued and outstanding for purposes of the Change in
Control.

         12. STOCKHOLDER APPROVAL. The Company shall obtain the approval of the
Plan by the Company's stockholders to the extent required to satisfy Section
162(m) of the Code or to satisfy or comply with any applicable laws or the rules
of any stock exchange or national market system on which the Common Stock may be
listed or quoted. No Award that is issued as a result of any increase in the
number of shares of Common Stock authorized to be issued under the Plan may be
exercised or forfeiture restrictions lapse prior to the time such increase has
been approved by the stockholders of the Company, and all such Awards granted
pursuant to such increase will similarly terminate if such shareholder approval
is not obtained.

         13. ADMINISTRATION. This Plan shall be administered by the Committee.
The Committee shall interpret the Plan and any Awards granted pursuant to the
Plan and shall prescribe such rules and regulations in connection with the
operation of the Plan as it determines to be advisable for the administration of
the Plan. The Committee may rescind and amend its rules and regulations from
time to time. The interpretation by the Committee of any of the provisions of
this Plan or any Award granted under this Plan shall be final and binding upon
the Company and all persons having an interest in any Option or any shares of
Common Stock acquired pursuant to an Award.

         14. EFFECT OF PLAN. Neither the adoption of the Plan nor any action of
the Board or the Committee shall be deemed to give any Employee, Director or
Consultant any right to be granted an Award or any other rights except as may be
evidenced by the Option Agreement or Restricted Stock Agreement, or any
amendment thereto, duly authorized by the Committee, or if applicable the Chief
Executive Officer, and executed on behalf of the Company, and then only to the
extent and on the terms and conditions expressly set forth therein. The
existence of the Plan and the Awards granted hereunder shall not affect in any
way the right of the Board, the Committee or the stockholders of the Company to
make or authorize any adjustment, recapitalization, reorganization or other
change in the Company's capital structure or its

business, any merger or consolidation or other transaction involving the
Company, any issue of bonds, debentures, or shares of preferred stock ahead of
or affecting the Common Stock or the rights thereof, the dissolution or
liquidation of the Company or any sale or transfer of all or any part of the
Company's assets or business, or any other corporate act or proceeding by or for
the Company. Nothing contained in the Plan or in any Option Agreement,
Restricted Stock Agreement, or in other related documents shall confer upon any
Employee, Director or Consultant any right with respect to such person's
Continuous Service or interfere or affect in any way with the right of the
Company or an Affiliate to terminate such person's Continuous Service at any
time, with or without cause.

         15. NO EFFECT ON RETIREMENT AND OTHER BENEFIT PLANS. Except as
specifically provided in a retirement or other benefit plan of the Company or an
Affiliate, Awards shall not be deemed compensation for purposes of computing
benefits or contributions under any retirement plan of the Company or an
Affiliate, and shall not affect any benefits under any other benefit plan of any
kind or any benefit plan subsequently instituted under which the availability or
amount of benefits is related to level of compensation. The Plan is not a
"Retirement Plan" or "Welfare Plan" under the Employee Retirement Income
Security Act of 1974, as amended.

         16. AMENDMENT OR TERMINATION OF PLAN. The Board in its discretion may,
at any time or from time to time after the date of adoption of the Plan,
terminate or amend the Plan in any respect, including amendment of any form of
Option Agreement, Restricted Stock Agreement, exercise agreement or instrument
to be executed pursuant to the Plan; provided, however, to the extent necessary
to comply with the Code, including Sections 162(m) and 422 of the Code, other
applicable laws, or the applicable requirements of any stock exchange or
national market system, the Company shall obtain stockholder approval of any
Plan amendment in such manner and to such a degree as required. No Award may be
granted after termination of the Plan. Any amendment or termination of the Plan
shall not affect Awards previously granted, and such Awards shall remain in full
force and effect as if the Plan had not been amended or terminated, unless
mutually agreed otherwise in a writing (including an Option Agreement or
Restricted Stock Agreement) signed by the Grantee and the Company.

         17. EFFECTIVE DATE AND TERM OF PLAN. The amendment and restatement of
Plan as set forth herein shall become effective upon its adoption by the Board.
It shall continue in effect for a term of ten (10) years from December 22, 1997,
the original effective date of the Plan, unless sooner terminated by action of
the Board. Subject to the terms and conditions of the Plan, as amended and
restated herein, and applicable laws, Awards may be granted under the Plan upon
its adoption.

         18. SEVERABILITY AND REFORMATION. The Company intends all provisions of
the Plan to be enforced to the fullest extent permitted by law. Accordingly,
should a court of competent jurisdiction determine that the scope of any
provision of the Plan is too broad to be enforced as written, the court should
reform the provision to such narrower scope as it determines to be enforceable.
If, however, any provision of the Plan is held to be wholly illegal, invalid, or
unenforceable under present or future law, such provision shall be fully
severable and severed, and the Plan shall be construed and enforced as if such
illegal, invalid, or

unenforceable provision were never a part hereof, and the remaining provisions
of the Plan shall remain in full force and effect and shall not be affected by
the illegal, invalid, or unenforceable provision or by its severance.

         19. GOVERNING LAW. The Plan shall be construed and interpreted in
accordance with the laws of the State of Texas.

         20. INTERPRETIVE MATTERS. Whenever required by the context, pronouns
and any variation thereof shall be deemed to refer to the masculine, feminine,
or neuter, and the singular shall include the plural, and visa versa. The term
"include" or "including" does not denote or imply any limitation. The captions
and headings used in the Plan are inserted for convenience and shall not be
deemed a part of the Plan for construction or interpretation.

                              EMPLOYMENT AGREEMENT

         This Employment Agreement (the "Agreement"), by and among Quanta
Services, Inc., a Delaware corporation ("Employer"), and Peter T. Dameris
("Employee"), is hereby entered into this April 1, 2001 (the "Execution Date").

                                    RECITALS

         A. As of the Execution Date, Employer is engaged primarily in the
business of specialized construction contracting and/or maintenance services to:
electric utilities; telecommunication, cable television and natural gas
operators; governmental entities; the transportation industry; and 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
Confidential Information (as defined in Section 9), all of which has been and
will be established and maintained at great expense to Employer and all or part
of which constitutes "trade secrets" of Employer and the valuable goodwill of
Employer.

                                   AGREEMENTS

         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 Executive Vice
         President and Chief Operating Officer of Employer effective as of
         February 5, 2001 (the "Effective Date"). As such, Employee shall have
         responsibilities, duties and authority reasonably accorded to and
         expected of an Executive Vice President and Chief Operating Officer of
         Employer and will report directly to the Chief Executive Officer of
         Employer (the "CEO"). Employee hereby accepts this employment upon the
         terms and conditions herein contained and, subject to Section 1(c),
         agrees to devote Employee's work time, attention and efforts to promote
         and further the business of Employer.

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

                  (c) Employee shall not, during the Term (as defined in Section
         5) of this Agreement, be engaged in any other business activity pursued
         for gain, profit or other pecuniary advantage if such activity
         substantially 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 services in the operation or
         affairs of the companies or enterprises in which such investments are
         made nor violate the terms of Section 3.

         2. Compensation. For all services rendered by Employee, Employer shall
compensate Employee as follows:

                  (a) Base Salary. The base salary payable to Employee beginning
         as of the Effective Date 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) Bonus.

                           (i) Employee will participate in the Management
                  Incentive Bonus Plan developed by Employer for the fiscal year
                  ending December 31, 2001. The maximum bonus for which Employee
                  will be eligible pursuant to such plan will be 100% of his
                  base salary; provided, however, in no event will Employee's
                  bonus for the fiscal year ending December 31, 2001 be less
                  than $200,000.

                           (ii) Employee will participate in the Management
                  Incentive Bonus Plan developed by Employer for the fiscal year
                  ending December 31, 2002. The maximum bonus for which Employee
                  will be eligible pursuant to such plan will be 100% of
                  Employee's base salary. Employee will participate in future
                  incentive bonus plans made available by Employer during the
                  Term of this Agreement, provided that the maximum bonus for
                  which Employee will be eligible pursuant to any such plan will
                  be 100% of his base salary at the time the bonus is given.

                  (c) Executive Perquisites, Benefits, and Other Compensation.
         Employee shall be entitled to receive, beginning as of the Effective
         Date, 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 will have in effect.

                           (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.
                  All reimbursable expenses shall be appropriately documented in
                  reasonable detail by Employee 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 that are available to other executives
                  generally and participation in all other benefits and
                  compensation plans or programs as available to other
                  executives from time to time.

                           (iv) Four weeks paid vacation per year.

<PAGE>   3

                           (v) Payment of attorney's fees, up to a maximum of
                  $6,000, incurred by Employee for his review and negotiation of
                  this Agreement.

                  (d) Restricted Stock. Subject to the provisions of Section 20,
         on or before the first to occur of (i) the adoption by Employer of an
         employee benefit plan providing for the issuance of restricted stock
         grants, (ii) a vesting event under clause (G) of Section 20(a)(xiii) or
         (iii) June 1, 2001, Employer agrees that it shall issue to Employee
         72,701 shares of Common Stock, $.00001 par value per share (the "Common
         Stock"), of Employer.

                  (e) Stock Options. On or before the Execution Date, Employer
         shall grant Employee nonqualified options to purchase 175,000 shares of
         Common Stock under Employer's 1997 Stock Option Plan. Except for
         extraordinary circumstances, on each successive anniversary of the
         Effective Date during the Term of this Agreement, Employer shall grant
         Employee nonqualified options to purchase 50,000 shares of Common Stock
         under Employer's 1997 Stock Option Plan, as it may be amended from time
         to time, or under, and subject to, the provisions of any similar plan
         providing for the grant of nonqualified stock options that may be
         adopted by Employer after the Execution Date. Options granted pursuant
         to this subsection shall be granted at an exercise price per share
         equal to the closing price of the Common Stock on the date of such
         grant and shall be substantially in the form of the grant agreement
         attached hereto as Exhibit A (the "Stock Option Agreement").

         3. Non-Competition.

                  (a) Employee hereby agrees that Employee will not, during the
         Term (as defined in Section 5) of this Agreement, and for a period of
         one (1) year following the end of the Term, for any reason whatsoever,
         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 Competitive
                  Business (as defined in Section 3(c)) or within 100 miles of
                  any other geographic area in which Employer or any of
                  Employer's direct or indirect subsidiaries conducts business,
                  including any territory serviced by Employer or any of its
                  subsidiaries (the "Territory");

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

                           (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

Employment Agreement -- Peter T. Dameris      3

<PAGE>   4

                  soliciting or selling products or services in a Competitive
                  Business within the Territory; or

                           (iv) call upon any prospective acquisition candidate,
                  on Employee's own behalf or on behalf of any competitor, which
                  candidate was, to Employee's actual knowledge after due
                  inquiry, either called upon by Employer including the direct
                  or indirect subsidiaries thereof) or for which Employer made
                  an acquisition analysis, for the purpose of acquiring such
                  entity.

         Notwithstanding the above, the foregoing covenant shall not be deemed
to prohibit Employee from acquiring as an investment not more than two percent
(2%)of the capital stock of a competing business, whose stock is traded on a
national securities exchange or over-the-counter.

                  (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 and restraining orders.

                  (c) It is agreed by the parties that the foregoing covenants
         in this Section 3 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). "Competitive Business" means any
         business that provides specialized construction contracting and/or
         maintenance services to: electric utilities; telecommunication, cable
         television or natural gas pipeline operators; governmental entities;
         the transportation industry; or commercial and/or industrial customers.

         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 the operation of which does not violate clause (a)(i)
of this Section 3, and such new business or activities are not in violation of
this Section 3 or of employee's obligations under this Section 3, Employee shall
not be chargeable with a violation of this Section 3 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 Section 3 are severable and
         separate, and the unenforceability of any specific covenant shall not
         affect the provisions of any other covenant. Moreover, in the event any
         court of competent jurisdiction shall determine that the scope, time or
         territorial restrictions set forth are unreasonable, then it is the
         intention of the parties that such restrictions be enforced to the
         fullest extent which the court deems reasonable, and the Agreement
         shall be reformed in accordance therewith.

                  (e) All of the covenants in this Section 3 shall be construed
         as an agreement independent of any other provision in this Agreement,
         and the existence of any claim or

Employment Agreement -- Peter T. Dameris      4

<PAGE>   5

         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.

                  (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 during which or for which the Employee is not receiving
         or has not received severance compensation.

         4. Place of Performance. Nothing contained herein shall be deemed to
require Employee to relocate from Employee's current residence to geographic
location other than the Houston, Texas metropolitan area to carry out Employee's
duties and responsibilities under this Agreement. In the event (i) Employer
requires Employee to relocate or (ii) Employer relocates its principal executive
office outside a 75-mile radius of the City of Houston, Texas without Employee's
written consent and as a result of such relocation Employee is the only
executive officer of Employer still based in Texas, Employee may immediately
terminate this Agreement, in which case (a) Employee shall receive from
Employer, in a lump-sum payment due on the effective date of termination of this
Agreement pursuant to the provisions of this Section 4, an amount equal to two
times Employee's base salary at the rate then in effect, (b) all options to
purchase Common Stock granted to Employee shall immediately vest and, for the
sole purpose of being eligible to exercise such options, Employee's employment
shall be deemed to continue for whatever time period is remaining under the
Initial Term or the then current Renewal Term of this Agreement, disregarding
the earlier termination of Employee's employment under this Section 4 and (c)
the Issued Shares (as defined in Section 20) shall vest in accordance with
clause (G) of the Vesting Schedule (as defined in Section 20(a)).

         5. Term; Termination; Rights on Termination. The term of this Agreement
shall begin on the Effective Date and continue for three (3) years (the "Initial
Term"), and, unless terminated sooner as herein provided, shall continue
thereafter on a year-to-year basis (each a "Renewal Term" and together with the
Initial Term, the "Term") on the same terms and conditions contained herein in
effect as of the time of renewal. This Agreement and 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,
         other than any payments provided for under any employee benefit plan or
         program.

                  (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

Employment Agreement -- Peter T. Dameris      5

<PAGE>   6

         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,
         Employee's base salary at the rate then in effect for whatever time
         period is remaining under the Initial Term or the then current Renewal
         Term of this Agreement, as applicable, or for one (1) year, whichever
         amount is greater and any other required payments provided under any
         welfare or benefit plan or program in which Employee is a participant.

                  (c) Good Cause Termination By Employer. Employer may terminate
         the Agreement thirty (30) days after delivery of written notice to
         Employee for good cause, which shall be: (1) Employee's willful,
         material and irreparable breach of this Agreement; (2) Employee's gross
         negligence in the performance or intentional nonperformance or
         inattention continuing for thirty (30) days after receipt of written
         notice of need to cure of any of Employee's material duties and
         responsibilities hereunder; (3) Employee's willful dishonesty, fraud or
         material misconduct with respect to the business or affairs of
         Employer; (4) Employee's conviction of a felony crime; or (5) 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.

                  (d) Without Good Cause. At any time after the commencement of
         employment, either Employee or Employer may, without good cause,
         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,
         (i) Employee shall receive from Employer, in a lump-sum payment due on
         the effective date of termination, an amount equal to two times
         Employee's base salary at the rate then in effect, (ii) any options to
         purchase Common Stock granted to Employee that would have vested on the
         next succeeding anniversary of the grant date following such
         termination shall vest pro rata from the first day following the
         anniversary of the grant date of such options immediately preceding
         such termination, up to and including the effective date of termination
         computed based on a 365-day year (or, if such termination occurs within
         the first year, the number of days that have elapsed subsequent to the
         Effective Date), and, for the sole purpose of being eligible to
         exercise all of his vested options, Employee's employment shall be
         deemed to continue for whatever time period is remaining under the
         Initial Term or the then current Renewal Term of this Agreement,
         disregarding its earlier termination on Employee's termination of
         employment under this Section 5(d) and (iii) the Issued Shares shall
         vest in accordance with clause (G) of the Vesting Schedule. If Employee
         resigns or otherwise terminates Employee's employment without cause
         pursuant to this Section 5(d), Employee shall receive no severance
         compensation.

Employment Agreement -- Peter T. Dameris      6

<PAGE>   7

                  (e) Change in Control of Employer. In the event of a Change in
         Control (as defined in Section 13) of Employer during the Term of this
         Agreement, refer to Section 13.

                  (f) Non-Renewal. In the event that Employer chooses not to
         renew this Agreement upon the expiration of the Initial Term or the
         then current Renewal Term of this Agreement, it shall give Employee
         written notice of this intent ninety (90) days before the expiration of
         such Initial Term or Renewal Term. In case of such non-renewal,
         Employee shall receive from Employer, in a lump-sum payment due on the
         date of expiration of such Initial Term or Renewal Term, an amount
         equal to Employee's base salary then in effect. If Employee resigns or
         otherwise terminates Employee's employment without cause pursuant to
         this Section 5(f), Employee shall receive no severance compensation.

                  (g) Change in Place of Performance. If there is a change in
         Employee's place of performance as set forth in Section 4, then
         Employee may terminate this Agreement pursuant to the terms of Section
         4.

                  (h) Other Effects of Termination Under Section 5(a)-(g). Upon
         termination of this Agreement 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 in this Section 5 or in Sections 4, 13 or 20(a)(xiii)(G). 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 Section 10 hereof and any other
         statutorily required obligations and Employee's obligations under
         Sections 3, 7, 8, 9, 11 and 17 hereof shall survive such termination in
         accordance with their terms.

         6. Good Cause Termination By Employee. 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 breach of this Agreement by Employer, Employer shall pay all amounts and
damages to which Employee may be entitled as a result of such breach, including
interest thereon at the maximum non-usurious rate and all reasonable legal fees
and expenses and other costs incurred by Employee to enforce Employee's rights
hereunder. A termination under this Section 6 will relieve Employee of all
obligations under Section 3.

         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. Because of the difficulty of measuring economic losses to
Employer as a result of a breach of this Section 7, and because of

Employment Agreement -- Peter T. Dameris      7

<PAGE>   8

the immediate and irreparable damage that could be caused to Employer for which
it would have no other remedy, Employee agrees that this Section 7 may be
enforced by Employer in the event of breach by him, by injunctions and
restraining orders.

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

                  (a) Both during the term of Employee's employment and after
         the termination of Employee's employment for any reason (including
         wrongful termination), Employee shall hold all Confidential Information
         in strict confidence, and shall not use any Confidential Information
         except for the benefit of Employer, in accordance with the duties
         assigned to Employee by Employer. Employee shall not, at any time
         (either during or after the term of Employee's employment), disclose
         any Confidential Information to any person or entity (except other
         employees of Employer who have a need to know the information in
         connection with the performance of their employment duties), or copy,
         reproduce, modify, decompile or reverse engineer any Confidential
         Information, or remove any Confidential Information from Employer's
         premises, without the prior written consent of Employer, or permit any
         other person to do so. Employee shall take reasonable precautions to
         protect the physical security of all documents and other material
         containing Confidential Information (regardless of the medium on which
         the Confidential Information is stored). This Agreement applies to all
         Confidential Information, whether now known or later to become known to
         Employee. It shall not be a violation of this Section 9(a) for Employee
         to disclose Confidential Information to the extent he is required to do
         so by law or order of any court; provided, however, that Employer shall
         be given notice of any such required disclosure.

                  (b) Upon the termination of Employee's employment with
         Employer for any reason (including wrongful termination), and upon
         request of Employer at any other time, Employee shall promptly
         surrender and deliver to Employer all documents and other written
         material of any nature containing or pertaining to any Confidential
         Information

Employment Agreement -- Peter T. Dameris      8

         and shall not retain any such document or other material. Within five
         days of any such request, Employee shall certify to Employer in writing
         that all such materials have been returned.

                  (c) As used in this Agreement, the term "Confidential
         Information" shall mean any information or material known to or used by
         or for Employer or any entity controlled by or under common control
         with Employer (each, an "Affiliate") (whether or not owned or developed
         by Employer or such Affiliate and whether or not developed by Employee)
         that (i) is not generally known to the public and (ii) was not
         disclosed to Employee by a third party having a legal right to disclose
         such information. Confidential Information includes, but is not limited
         to, the following: (A) all trade secrets of Employer and its
         Affiliates; (B) all information that Employer or any Affiliate has
         marked as confidential or has otherwise described to Employee (either
         in writing or orally) as confidential; (C) all nonpublic information
         concerning Employer's and its Affiliates' products, services,
         prospective products or services, research, product designs, prices,
         discounts, costs, marketing plans, marketing techniques, market
         studies, competition, test data, customers, customer lists and records,
         suppliers or contracts; (D) all business records and plans of Employer
         and its Affiliates; (E) all personnel files of Employer and its
         Affiliates; (F) all financial information of or concerning Employer and
         its Affiliates; (G) all information relating to operating system
         software, application software, software and system methodology,
         hardware platforms, technical information, inventions, computer
         programs and listings, source codes, object codes, copyrights, or other
         intellectual property; (H) all technical specifications; (I) any
         proprietary information belonging to Employer or any Affiliate; and (J)
         all of Employer's or any Affiliate's computer hardware or software,
         training or instruction manuals and data and computer system passwords
         and user codes.

         Because of the difficulty of measuring economic losses to Employer as a
result of a breach of this Section 9, 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 this Section 9 may be enforced by
Employer in the event of a breach by Employee by injunctions and restraining
orders.

         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. 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,

Employment Agreement -- Peter T. Dameris      9

<PAGE>   10

willful or wanton negligence or misconduct or performed criminal and fraudulent
acts which 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 Effective Date.

         12. Assignment; Binding Effect. Employee understands that he has been
selected for employment by Employer 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. Subject to the
preceding two (2) sentences and the express provisions of Section 13, 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 in no event
         shall the Term of this Agreement expire prior to the first anniversary
         of such Change in Control and the provisions of this Section 13 shall
         be applicable during such period.

                  (b) In any Change in Control situation, Employee may, at his
         sole discretion, elect to terminate this Agreement by providing written
         notice to Employer at least five (5) business days prior to the
         anticipated closing of the transaction giving rise to the Change in
         Control. In such case, the applicable provisions of Section 5(d) will
         apply as though Employer had terminated this Agreement without cause;
         provided, however, under such circumstances (i) the amount of the
         lump-sum severance payment due to the Employee shall be equal to one
         and one-half times the amount calculated under the terms of Section
         5(d)(i), (ii) all options to purchase Common Stock granted to Employee
         shall immediately vest (to the extent not already fully vested under
         the terms of the Stock Option Agreement) and, for the sole purpose of
         being eligible to exercise such options, Employee's employment shall be
         deemed to continue for whatever time period is remaining under the
         Initial Term or the then current Renewal Term of this Agreement,
         disregarding the earlier termination of Employee's employment under
         this Section 13, (iii) the Issued Shares shall vest in accordance with
         clause (G) of the Vesting Schedule as applicable to a Change in Control
         and (iv) the noncompetition provisions of Section 3 shall not apply.

Employment Agreement -- Peter T. Dameris      10

<PAGE>   11

                  (c) For purposes of applying Section 5 under the circumstances
         described in subsection (b) above, the effective date of termination
         will be the closing date of the transaction giving rise to the Change
         in Control and all compensation, reimbursements and lump-sum payments
         due Employee must be paid in full by Employer at or prior to such
         closing. Further, 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, any subsequent plan and/or the Stock Option Agreement,
         such that Employee may convert the options to shares of 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 that it will assume Employer's obligations under
         this Agreement and Employee chooses not to terminate this Agreement
         pursuant to the provisions of subsection (b) above, and at the time of
         or within twelve (12) months following such Change in Control either
         (i) Employee incurs a change that constitutes a Lesser Position (as
         defined in Section 13(f)) or (ii) Employee is terminated other than
         pursuant to Section 5(c), then effective as of the date Employee is
         caused to be in a Lesser Position or the effective date of such
         termination, whichever is applicable, such event shall be deemed to be
         a termination of this Agreement by Employer without good cause during
         the Term and the applicable portions of Section 5(d) will apply;
         provided, however, under such circumstances, (A) the amount of the
         lump-sum severance payment due to the Employee shall be equal to one
         and one-half times the amount calculated under the terms of Section
         5(d)(i), (B) all options to purchase Common Stock granted to Employee
         shall immediately vest (to the extent not already fully vested under
         the terms of the Stock Option Agreement) and, for the sole purpose of
         being eligible to exercise such options, Employee's employment shall be
         deemed to continue for whatever time period is remaining under the
         Initial Term or the then current Renewal Term of this Agreement,
         disregarding the earlier termination of Employee's employment under
         this Section 13, (C) the Issued Shares shall vest in accordance with
         clause (G) of the Vesting Schedule as applicable to a Change in Control
         and (D) the noncompetition provisions of Section 3 shall not apply.

                  (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;

                           (ii) John R. Colson is not the Chief Executive
                  Officer of Employer, unless Employee has immediately succeeded
                  John R. Colson as Chief Executive Officer;

Employment Agreement -- Peter T. Dameris      11

<PAGE>   12

                           (iii) the stockholders of Employer shall approve a
                  merger, consolidation, recapitalization or reorganization of
                  Employer, a reverse stock split of outstanding voting
                  securities or consummation of any such transaction if
                  stockholder approval is not obtained, other than any such
                  transaction which would result in at least 75% of the total
                  voting power represented by the voting securities of the
                  surviving entity outstanding immediately after such
                  transaction being Beneficially Owned by at least 75% of the
                  holders of outstanding voting securities of Employer
                  immediately prior to the transaction, with the voting power of
                  each such continuing holder relative to other such continuing
                  holders not substantially altered in the transaction; or

                           (iv) the stockholders of Employer shall approve a
                  plan of complete liquidation of Employer or 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).

                  (f) "Lesser Position" shall mean a new position or a change in
         Employee's position, which, compared with Employee's position
         immediately prior to the Change in Control, (i) reduces Employee's
         compensation (including base salary, fringe benefits or incentive
         compensation opportunities (as determined in good faith by Employee)
         under any corporate-performance based bonus and incentive programs), or
         (ii) materially reduces Employee's duties, status, reporting
         requirements or level of responsibility, or (iii) requires Employee to
         change his place of performance as provided in Section 4.

                  (g) Employee shall be reimbursed by Employer or its successor
         for all excise taxes that Employee incurs under Section 4999 of the
         Internal Revenue Code of 1986, as amended (the "Code"), as a result of
         any "change in control," within the meaning of Section 280G of the Code
         without regard as to whether such "parachute payment" is made pursuant
         to this Agreement. In addition, Employee shall be reimbursed by
         Employer or its successor for all taxes (including any penalties and
         interest) and additional excise taxes attributable to the payment
         pursuant to the preceding sentence and the payment pursuant to this
         sentence. Such amount will be due and payable by Employer or its
         successor on the date Employer is required to withhold such excise tax,
         and in no event not later than within ten (10) days after Employee
         delivers a written request for reimbursement accompanied by a copy of
         Employee's tax return(s) showing the excise tax actually incurred by
         Employee. Such amount 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 by Employer when due, the amount due under this
         subsection shall bear interest at the maximum non-usurious rate allowed
         by law from the due date to the date of payment.

         14. Complete Agreement. This Agreement supersedes any other agreements
or understandings, written or oral, between Employer and Employee, and Employee
has no oral representations, understandings or agreements with Employer or any
of its officers, directors or representatives covering the same subject matter
as this Agreement. This written Agreement is the final, complete and exclusive
statement and expression of the agreement between Employer and Employee and of
all the terms of this Agreement, and it cannot be varied, contradicted or

supplemented by evidence of any prior or contemporaneous oral or written
agreements. This written Agreement may not be later modified except by a written
instrument signed by a duly authorized officer of Employer and Employee, and no
term of this Agreement may be waived except by a written instrument signed by
the party waiving the benefit of such term

                                    (G) Notwithstanding anything to the contrary
                           in clauses (A)-(F) above, Employee shall immediately
                           acquire a vested interest in, and the Cancellation
                           Right shall lapse with respect to, (1) all of the
                           Issued Shares upon a Change in Control as defined in
                           Section 13 or if Employee's employment is terminated
                           pursuant to Section 4, and (2) if Employee's
                           employment is terminated by Employer pursuant to
                           Section 5(d), a pro rata number of the Issued Shares
                           that would have vested on the next succeeding
                           anniversary of the Effective Date following such
                           termination shall vest on such termination date based
                           on the number of days that have lapsed since the
                           anniversary of the Effective Date immediately
                           preceding such termination (or, if such termination
                           occurs within the first year, the number of days that
                           have lapsed subsequent to the Effective Date) up to
                           and including the date of such termination over 365.

                  (b) Purchase Price. Employer shall issue the Issued Shares,
         subject to the terms and conditions set forth in this Section 20, upon
         payment by Employee to Employer in cash of the Purchase Price.

                  (c) Stockholder Rights. Until such time as Employer exercises
         the Cancellation Right, Employee shall have all the rights of a
         stockholder (including voting, dividend and liquidation rights) with
         respect to the Issued Shares, subject, however, to the restrictions
         contained in this Section 20.

                  (d) Securities Law Compliance.

                           (i) Restricted Securities. If the Issued Shares have
                  not been registered under the 1933 Act and are being issued to
                  Employee in reliance upon the exemption for such registration
                  provided by Section 4(2) of the 1933 Act, Employee hereby
                  confirms that Employee has been informed that the Issued
                  Shares will be restricted securities under the 1933 Act and
                  may not be resold or transferred unless the Issued Shares are
                  first registered under the federal securities laws or unless
                  an exemption from such registration is available. Accordingly,
                  subject to the further provisions of this Section 20, Employee
                  hereby acknowledges that Employee is prepared to hold the
                  Issued Shares for an indefinite period and that Employee is
                  aware of the requirements of Rule 144 and other exemptions
                  from the registration requirements of the 1933 Act.

                           (ii) Restrictions on Disposition of Issued Shares.
                  Subject to the further provisions of this Section 20, if the
                  Issued Shares have not been registered under the 1933 Act, the
                  Employee shall make no disposition of the Issued Shares (other
                  than a Permitted Transfer) unless and until there is
                  compliance with all of the following requirements:

                                    (A) Employee shall have furnished Employer
                           with a written summary of the terms and conditions of
                           the proposed disposition.

                                    (B) Employee shall have complied with all
                           requirements of this Agreement applicable to the
                           disposition of the Issued Shares.

                                    (C) Employee shall have provided Employer
                           with written assurances, in form and substance
                           satisfactory to Employer, that (1) the proposed
                           disposition does not require registration of the
                           Issued Shares under the 1933 Act or (2) all
                           appropriate action necessary for compliance with the
                           registration requirements of the 1933 Act or any
                           exemption from registration available under the 1933
                           Act (including Rule 144) has been taken.

                           (iii) Restrictive Legends.

                                    (A) If the Issued Shares have not been
                           registered under the 1933 Act, the stock certificates
                           (and separate certificates may be issued for each
                           regularly scheduled vesting tranche) for all of the
                           Issued Shares shall be endorsed with the following
                           restrictive legend:

                                    "THE SHARES REPRESENTED BY THIS CERTIFICATE
                           HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF

                           IN THE ABSENCE OF (a) AN EFFECTIVE REGISTRATION
                           STATEMENT FOR THE SHARES UNDER SUCH ACT, (b) A `NO
                           ACTION' LETTER OF THE SECURITIES AND EXCHANGE
                           COMMISSION WITH RESPECT TO SUCH SALE OR OFFER OR (c)
                           SATISFACTORY ASSURANCES TO THE ISSUER THAT

                           RESPECT TO SUCH SALE OR OFFER."

                                    (B) In addition to any restrictive legend
                           required pursuant to clause (A) above, stock
                           certificates (and separate certificates may be issued
                           for each regularly scheduled vesting tranche)
                           representing Unvested Shares (as defined below) shall
                           be endorsed with the following restrictive legend:

                                    "THE SHARES REPRESENTED BY THIS CERTIFICATE
                           ARE SUBJECT TO CERTAIN CANCELLATION RIGHTS GRANTED TO

                           TRANSFERRED, ENCUMBERED, OR IN ANY MANNER DISPOSED OF

                           AGREEMENT DATED AS OF MARCH 12, 2001 BETWEEN THE
                           ISSUER AND THE REGISTERED HOLDER OF THE SHARES FOR
                           THE PREDECESSOR IN INTEREST TO THE SHARES. A COPY OF
                           SUCH AGREEMENT IS MAINTAINED AT THE ISSUER'S
                           PRINCIPAL CORPORATE OFFICES.

                  (e) Transfer Restrictions.

                           (i) Restrictions on transfer. Except for a Permitted
                  Transfer, Employee shall not transfer, assign, encumber or
                  otherwise dispose of any of the Issued Shares that are subject
                  to the Cancellation Right.

<PAGE>   18

                           (ii) Transferee Obligations. Each person to whom the
                  Issued Shares are transferred by means of a Permitted Transfer
                  must, as a condition precedent to the validity of such
                  transfer, acknowledge in writing to Employer that such person
                  is bound by the provisions of this Agreement and that the
                  transferred shares are subject to the Cancellation Right, to
                  the same extent such shares would be so subject if retained by
                  Employee.

                           (iii) Employer Obligations. Employer shall not be
                  required (A) to transfer on its books any Issued Shares that
                  have been sold or transferred in violation of the provisions
                  of this Agreement or (B) to treat as the owner of the Issued
                  Shares, or otherwise to accord voting, dividend or liquidation
                  rights to, any transferee to whom the Issued Shares have been
                  transferred in contravention of this Agreement.

                  (f) Cancellation Right.

                           (i) Grant. Employer is hereby granted the right (the
                  "Cancellation Right"), exercisable at any time during the
                  ninety (90) day period following the date Employee ceases for
                  any reason to remain in Service to cancel, without any
                  additional consideration, all or any portion of the Issued
                  Shares in which Employee is not, at the time of his cessation
                  of Service, vested in accordance with the Vesting Schedule,
                  including clause (G) thereof, (such shares to be hereinafter
                  referred to as the "Unvested Shares").

                           (ii) Exercise of the Cancellation Right. The
                  Cancellation Right shall be exercisable by written notice
                  delivered to Employee and any recipient of a Permitted
                  Transfer of Unvested Shares prior to the expiration of the
                  ninety (90) day exercise period. The notice shall indicate the
                  number of Unvested Shares to be cancelled. The cancellation
                  shall be effective immediately after giving of notice in
                  accordance with the terms of this Agreement and with no
                  further action on the part of the holder of Unvested Shares.
                  The certificates representing the shares so cancelled shall be
                  promptly delivered to Employer, but failure to deliver such
                  certificates shall not affect the effectiveness of such
                  cancellation.

                           (iii) Termination of the Cancellation Right. The
                  Cancellation Right shall terminate with respect to any
                  Unvested Shares for which it is not timely exercised under
                  Section 20(f)(ii). In addition, the Cancellation Right shall
                  terminate and cease to be exercisable with respect to any and
                  all Issued Shares in which Employee vests in accordance with
                  the Vesting Schedule, including clause (G) thereof.

                           (iv) Recapitalization. Any new substituted or
                  additional securities or other property (including cash paid
                  other than as a regular cash dividend) which is by reason of
                  any Recapitalization distributed with respect to the Issued
                  Shares shall be immediately subject to the Cancellation Right,
                  but only to the extent the related Issued Shares are at the
                  time covered by such right, and such Cancellation Right shall
                  lapse as to such other securities or property at the same time
                  as it

                  lapses or would lapse) with respect to the related Issued
                  Shares. Appropriate adjustments to reflect such distribution
                  shall be made to the number and/or class of Issued Shares
                  subject to this Agreement to reflect the effect of any such
                  Recapitalization upon Employer's capital structure.

                  (v) Corporate Transaction.

                           (A) The Cancellation Right shall be assignable to the
                  successor entity in any Corporate Transaction. However, to the
                  extent the successor entity does not accept such assignment,
                  the Cancellation Right shall lapse immediately prior to the
                  consummation of the Corporate Transaction.

                           (B) To the extent the Cancellation Right remains in
                  effect following a Corporate Transaction, such right shall
                  apply to the new capital stock or other property (including
                  any cash payments) received in exchange for the Issued Shares
                  in consummation of the Corporate Transaction, but only to the
                  extent the Issued Shares are at the time covered by such
                  right.

                  (g) Withholding of Taxes. At the time and to the extent vested
         Issued Shares become compensation income to Employee for federal or
         state income tax purposes, Employee either shall deliver to Employer
         such amount of money as required to meet Employer's minimum obligation
         under applicable tax laws or regulations, or, in lieu of cash,
         Employee, in his sole discretion, may elect to surrender, or direct
         Employer to withhold from the Issued Shares, shares of Common Stock
         (valued at their fair market value on the date of surrender or
         withholding of such shares) in such number as necessary to satisfy
         either (i) Employer's minimum tax withholding obligations or (ii)
         Employee's tax obligation as anticipated by Employee, by reason of such
         compensation income, whichever Employee elects.
