                              WCA WASTE CORPORATION

                            MANAGEMENT INCENTIVE PLAN

I. BACKGROUND AND OBJECTIVES

The overall executive compensation strategy of WCA Waste Corporation ("WCA" or
"the Company") is to provide key executives with total direct pay opportunity
that generally is competitive with similar waste management companies. The two
primary elements of the WCA cash compensation program are base salary and the
Management Incentive Plan (the "MIP" or the "Plan"). WCA base salaries generally
are competitive with industry standards and are used to reward an executive's
sustained job performance over time. The MIP rewards annual performance and is
described in detail in this document.

The MIP for WCA provides annual incentive compensation opportunity for key
executives for achieving critical financial goals of WCA and individual
performance achievement. The following provisions hereof define MIP eligibility,
the size of potential award opportunities, performance measurement, form and
timing of award payments, administrative guidelines and definitions for ongoing
MIP management.

II. ELIGIBILITY

MIP award eligibility will be approved by the Compensation Committee of the WCA
Board of Directors (the "Compensation Committee") at the beginning of each
performance/award period. Generally, MIP participants will be selected from key
executives who primarily are responsible for the annual growth and profitability
of WCA, i.e., generally senior vice presidents and above. The number of eligible
MIP participants is expected to vary from year to year, as WCA expands and as
the Company's compensation strategy and programs are refined.

III. AWARD OPPORTUNITIES

At the beginning of each fiscal year, each participant in the MIP will be
assigned a targeted award opportunity, expressed as a percent of salary, that
can decrease to zero, based on performance achievement. MIP award opportunities
may be redefined from time to time, as

                                        1
<PAGE>

modifications are made in WCA's executive compensation strategy. For 2005, the
MIP targeted award opportunity for the CEO and COO will be 100% of salary, with
80% of salary targets for two additional senior officer participants.

Within 2 1/2 months after the end of each fiscal year, each participant's salary
rate at the end of the prior fiscal year (just ended) will be multiplied by the
actual MIP award percentage earned to determine the dollar value of the award
for the prior performance cycle.

IV. PERFORMANCE MEASURES

The MIP will provide annual incentive pay at risk, with potential MIP awards
tied to WCA goal achievement and individual executive performance. When MIP
performance goals are met, the MIP awards plus base salary will approximate
total cash pay near the 75th percentile of the market ranges for most plan
participants.

The two primary performance measures for 2005 will be:

      -     TARGETED EBITDA GROWTH, WEIGHTED 40%; AND

      -     TARGETED EPS GROWTH, WEIGHTED 40%.

The Compensation Committee and the senior officers of WCA jointly will set MIP
performance targets at the beginning of each fiscal year. Performance goals for
MIP awards may be equal to or exceed the goals in the WCA business plan. MIP
performance goals may be adjusted by the Compensation Committee during the year,
if a major change occurs in the Company's capital structure, e.g., a major
acquisition.

In addition to the MIP targets, the Compensation Committee and the senior
officers of WCA jointly will establish a minimum acceptable performance goals,
i.e., the performance levels below which no incentive will be paid. MIP awards
will be interpolated for actual performance falling between the minimum
acceptable and targeted goals. Prior to fiscal year end, the WCA senior officers
and Compensation Committee jointly will establish appropriate MIP goals for the
next fiscal year, in support of the new WCA business plan.

Exhibit 1 presents the performance matrix for calculating MIP awards for 2005.
This performance matrix may be revised in the future, as the Company's business
strategy and performance focus of WCA changes.

V. INDIVIDUAL PERFORMANCE MEASURES

After 80% of each MIP award has been determined based on overall WCA
performance, the final 20% will be based on individual performance
contributions. Individual performance contributions will be measured in light of
two to three written goals established at the beginning of each year, plus any
other significant personal contributions made during the year. Sample MIP
calculations covering both corporate and individual MIP performance adjustments
are shown in Exhibit 2.

VI. FORM AND TIMING OF ANNUAL AWARD COMPONENTS

MIP awards will be paid in a lump sum in cash annually within 2 1/2 months after
year-end; provided, however, the Company shall deduct from all MIP awards
payable under this Plan any taxes required to be withheld by the Federal or any
state or local government. No participant shall be permitted to elect to defer
all or any portion of his/her award relating to any relevant measurement period
hereunder.

All awards payable under this Plan shall be the obligation of the Company. If
the Company determines that any person entitled to payments under this Plan is
physically or mentally incompetent to receive or properly receipt for such
payments, the Company shall make such payments to the legal guardian or other
personal representative of such person for the use and benefit of such person.
If the Company for any reason is unable to determine with reasonable certainty
the proper person to pay pursuant to the terms of the immediately preceding
sentence, the Company shall pay any amounts due hereunder into a court of
competent jurisdiction in an interpleader proceeding for purposes of being
directed by such court as to the proper disposition of any such amounts due
hereunder. Any such payments so made by the Company, to the extent of the
amounts thereof, shall fully discharge the Company's obligations hereunder.

Should the participant die prior to receiving all amounts due under this Plan,
any unpaid amounts due hereunder shall be made to the participant's spouse, if
such spouse survives the participant,

                                        3
<PAGE>

or, if there is no surviving spouse, to the legal representative of the
participant's estate, or if no administration is had on the estate, to the
person or persons to whom participant's property shall pass by applicable laws
of descent and distribution.

VII. ADMINISTRATIVE GUIDELINES AND DEFINITIONS

The MIP shall be administered by the Compensation Committee. The Compensation
Committee shall have such authority and powers and may consult with WCA's CEO or
such other person or persons as it shall deem necessary or advisable to
facilitate the intent and purpose of the MIP. All decisions made by the
Compensation Committee shall be final and binding.

      -     Employee Termination - A participant must be an employee of the
            Company on the final day of the measurement period.

      -     New Hires - Newly hired participants shall earn MIP awards on a
            pro-rata basis, based on their date of employment.

      -     Base Salary Rate - Base salary for MIP award calculations shall be
            the annualized base rate in effect at the end of the performance
            cycle for which the award is paid.

      -     Support Documentation - The WCA CFO shall be responsible for
            maintaining all necessary support documentation regarding
            performance and bonus calculations under the MIP.

VIII. MISCELLANEOUS

            (i)   Give the participant any rights whatsoever with respect to any
                  MIP award until such award becomes vested, nonforfeitable and
                  distributable in accordance with the terms of this Plan;

            (ii)  Limit in any way the right of the Company to terminate the
                  participant's employment by the Company at any time;

                                        4
<PAGE>

            (iii) Give the participant or any other person any interest in any
                  fund or in any specific asset or assets of the Company;

            (iv)  Give the participant or any other person any interest or right
                  other than those of any unsecured general creditor of the
                  Company; or

            (v)   Be evidence of any agreement or understanding, express or
                  implied, that the Company will employ the participant in any
                  particular position or at any particular rate of remuneration.

      (b)   NONALIENATION OF BENEFITS. No right or benefit under this Plan shall
            be subject to anticipation, alienation, sale, assignment, pledge,
            encumbrance, or charge, and any attempt to anticipate, alienate,
            sell, assign, pledge, encumber, or charge the same will be void. No
            right to interest hereunder shall in any manner be liable for or
            subject to any debts, contracts, liabilities, or torts of the person
            entitled to such right or interest.

      (c)   PREREQUISITES TO BENEFITS. Neither the participant, nor any person
            claiming through the participant, shall have any right or interest
            in this Plan, or any MIP award hereunder, unless and until all the
            terms, conditions, and provisions of this Plan which affect the
            participant or such other person shall have been complied with as
            specified herein.

      (d)   SECTION 162m COMPLIANCE. Should any participant in the Plan be or
            become a "covered employee" as such term is defined in section
            1.162-27(c)(2) of the Treasury Regulations, then notwithstanding
            anything herein to the contrary, with respect to any action taken
            under the Plan by the Compensation Committee in respect of any such
            covered employee, the Compensation Committee shall be comprised
            solely of two or more "outside directors" of the Company as such
            term is defined in section 1.162-27(e)(3) of the Treasury
            Regulations, the material terms of the Plan shall be disclosed to
            and approved by the stockholders of the Company prior to the payment
            of any MIP awards and the Plan shall, in all other respects, meet
            the requirements of section 162(m) of the Code and the regulations

                                        5
<PAGE>

            promulgated pursuant thereto, prior to any payments hereunder. In
            furtherance of the above provisions of this Section VIII(d), the
            Compensation Committee shall bifurcate the Plan so as to restrict,
            limit or condition the use or application of any provision of the
            Plan to participants who are covered employees without so
            restricting, limiting or conditioning the Plan with respect to other
            participants, unless the Compensation Committee, in its sole
            discretion, determines to apply such restrictions, limitations or
            conditions to participants who are not covered employees.

      (e)   BONUS ARRANGEMENT. This Plan is intended to be a bonus program that
            is designed to provide an on-going, pecuniary incentive for the
            participant to produce the participant's best efforts to increase
            the value of the Company. This Plan is not intended to provide
            retirement income or to defer the receipt of payments hereunder to
            the termination of the participant's covered employment or beyond.
            This Plan is strictly an incentive bonus program (as described in
            U.S. Department of Labor Regulation Section 2510.3-2(c) or any
            successor thereto), and not a pension or welfare benefit plan that
            is subject to the Employee Retirement Income Security Act of 1974,
            as amended ("ERISA"). All interpretations and determinations
            hereunder shall be made on a basis consistent with the status of the
            Plan as a bonus program.

      (f)   AMENDMENT. This Plan may be modified or terminated by the Company at
            any time; provided, however, that no such modification or
            termination shall affect any right to any MIP awards that are vested
            at the time of such modification or termination except with the
            written consent of the affected participant.

      (g)   POWERS OF THE COMPANY. The existence of outstanding and unpaid
            contingent interests under the Plan shall not affect in any way the
            right or power of the Company to make or authorize any adjustments,
            recapitalization, reorganization or other changes in the Company's
            capital structure or in its business, or any merger or consolidation
            of the Company, or any issue of bonds, debentures, common or
            preferred stock, if applicable, or the dissolution or liquidation of
            the

                                        6
<PAGE>

            Company, or any sale or transfer of all or any part of its assets or
            business, or any other act or proceeding, whether of a similar
            character or otherwise.

      (h)   WAIVER. A waiver by the Company, or the participant, of any of the
            terms or conditions contained in the Plan shall not be construed as
            a general waiver by such party of any other terms or conditions
            contained in this Plan.

      (i)   SEPARABILITY. If any provision or provisions of this Plan shall be
            found to be invalid, illegal, or unenforceable in any respect, such
            invalid, illegal, or unenforceable provision shall be severed from
            this Plan and shall not affect the validity, legality and
            enforceability of the remainder of this Plan.

      (j)   GENDER, TENSE AND HEADINGS. Whenever the context requires, words of
            the masculine gender used herein shall include the feminine and
            neuter, and words used in singular shall include plural. Headings of
            Articles and Sections, as used herein, are inserted solely for
            convenience and reference and constitute no part of this Plan.

      (k)   GOVERNING LAW. This Plan shall be subject to and governed by the
            laws of the State of Texas and, to the extent applicable, the laws
            of the United States.

      (l)   NOTICE. Any notice required or permitted to be given under this Plan
            shall be sufficient if in writing and hand delivered, or sent by
            registered or certified mail, to the Compensation Committee, the
            Company, participant or beneficiary, as applicable, at the address
            last furnished by such person. Such notice shall be deemed given as
            of the date of delivery or, if delivery is made by mail, as of the
            dates shown on the postmark on the receipts for registration or
            certification.

      (m)   EFFECTIVE DATE. This Plan is effective as of January 1, 2005 and any
            amendment of this Plan shall be effective as of the date provided
            therein.

                    2004 WCA WASTE CORPORATION INCENTIVE PLAN

                             RESTRICTED STOCK GRANT

      1. GRANT OF RESTRICTED SHARES. WCA Waste Corporation, a Delaware
corporation (the "Company"), hereby grants to ___ ("Participant") all rights,
title and interest in the record and beneficial ownership of ___ (___) shares
(the "Restricted Shares") of common stock, $0.01 par value per share, of the
Company ("Common Stock"), subject to the conditions described in this grant of
Restricted Stock (the "Grant") and in the 2004 WCA Waste Corporation Incentive
Plan (the "Plan"). The Restricted Shares are granted, effective as of ___,
20___ (the "Grant Date"). All capitalized terms not otherwise defined herein
shall have the meaning set forth in the Plan.

      2. ISSUANCE AND TRANSFERABILITY. Certificates representing the shares
granted hereunder shall be registered in the name of the Participant and during
the Restricted Period shall be left on deposit with the Company, and shall be
marked with the following legend:

      "The shares represented by this certificate have been issued pursuant to
      the terms of the 2004 WCA Waste Corporation Incentive Plan and may not be
      sold, pledged, transferred, assigned or otherwise encumbered in any manner
      except as is set forth in the terms of such award effective as of ___,
      20___."

No right or benefit hereunder shall in any manner be liable for or subject to
any debts, contracts, liabilities, or torts of Participant.

      3. RISK OF FORFEITURE. Except as otherwise provided in this Grant,
Participant shall immediately forfeit all rights to any nonvested portion of the
Restricted Shares in the event of termination, resignation or removal from Board
service under circumstances that do not cause Participant to become fully vested
under the terms of the Plan.

      4. VESTING. Subject to Paragraph 3 hereof, Participant shall fully vest in
his or her rights under the Restricted Shares and the Company's right to
repurchase such shares shall lapse with respect to 100% of the Restricted Shares
on January 1, 20___. Notwithstanding the provisions of the immediately preceding
sentence to the contrary, 100% of any otherwise nonvested Restricted Shares
shall become fully vested upon termination of Participant's Board service on
account of his death, Disability or a Change in Control.

      5. OWNERSHIP RIGHTS. Subject to the restrictions set forth in this Grant,
the Plan and Paragraph 8, Participant is entitled to all voting and ownership
rights applicable to the Restricted Shares, including the right to receive any
cash dividends which shall be accrued during the restriction period and shall be
paid as the Restricted Shares vest.

      6. CERTAIN RESTRICTIONS. By executing this Grant, Participant acknowledges
that he or she has received a copy of the Plan and that the Restricted Shares
are subject to all of the restrictions set forth in the Plan, and agrees that he
or she will enter into such written representations, warranties and agreements
and execute such documents as the Company may reasonably request in order to
comply with the securities law or any other applicable laws, rules or
regulations, or with this document or the terms of the Plan.

      7. REORGANIZATION OF THE COMPANY. The existence of this Grant shall not
affect in any way the right or power of the Company or its stockholders to make
or authorize any or all adjustments, recapitalizations, reorganizations or other
changes in the Company's capital structure or its business; any merger or
consolidation of the Company; any issue of bonds, debentures, preferred or prior
preference stock ahead of or affecting the Restricted Shares or the rights
thereof; the dissolution or liquidation of the Company, or any sale or transfer
of all or any part of its assets or business, or any other corporate act or
proceeding, whether of a similar character or otherwise.

      8. RECAPITALIZATION EVENTS. In the event of stock dividends, spin-offs of
assets or other extraordinary dividends, stock splits, combinations of shares,
recapitalizations, mergers, consolidations, reorganizations, liquidations,
issuances of rights or warrants and similar transactions or events involving the
Company ("Recapitalization Events"), then for all purposes references herein to
Common Stock or to Restricted Shares shall mean and include all securities or
other property (other than cash) that holders of Common Stock of the Company are
entitled to receive in respect of Common Stock by reason of each successive
Recapitalization Event, which securities or other property (other than cash)
shall be treated in the same manner and shall be subject to the same
restrictions as the underlying Restricted Shares.

      9. AMENDMENT AND TERMINATION. No amendment or termination of this Grant
shall be made by the Company at any time without the written consent of
Participant.

      10. WITHHOLDING OF TAXES. Participant agrees that, if he makes an election
under Section 83(b) of the Internal Revenue Code of 1986, as amended, with
regard to the Restricted Shares, he will so notify the Company in writing within
two (2) days after making such election, so as to enable the Company to timely
comply with any applicable governmental reporting requirements. The Company
shall have the right to take any action as may be necessary or appropriate to
satisfy any federal, state or local tax withholding obligations.

      11. NO GUARANTEE OF TAX CONSEQUENCES. The Company makes no commitment or
guarantee to Participant that any federal or state tax treatment will apply or
be available to any person eligible for benefits under this Grant.

      12. NO GUARANTEE OF BOARD SERVICE. Nothing herein shall be construed as
limiting any right which the Board or the stockholders may have to terminate at
any time, with or without cause, the Board service of any person.

      13. SEVERABILITY. In the event that any provision of this Grant shall be
held illegal, invalid, or unenforceable for any reason, such provision shall be
fully severable and shall not affect the remaining provisions of this Grant, and
the Grant shall be construed and enforced as if the illegal, invalid, or
unenforceable provision had never been included herein.

      14. GOVERNING LAW. The Grant shall be construed in accordance with the
laws of the State of Delaware to the extent that federal law does not supersede
and preempt Delaware law.
