      then listed;

the Merger Agreement and (b) any securities issued or issuable with respect to
such Common Stock by way of a stock dividend or stock split or in connection

reorganization; provided that any such share or security shall be deemed to be
Registrable Securities only if and so long as it is a Transfer Restricted
Security.

      Registration Statement: Any registration statement which covers
Registrable Securities pursuant to the provisions of this Agreement, including

securities transaction or sold in a transaction exempt from the registration and
prospectus delivery requirements of the Securities Act under Rule 144(k)
promulgated thereunder (or any successor rule other than Rule 144A). A security
shall cease being a Transfer Restricted Security if (i) all stop transfer
instructions or notations and restrictive legends with respect to such security
are eligible to be removed, and (ii) the holder of such security has received an
opinion of counsel to the Company, to the effect that such shares in such
holder's hands are freely transferable in any public or private transaction
without registration under the Securities Act (or such holder has waived receipt
of such opinion).

      Underwritten Registration or Underwritten Offering: A registration in
which securities of the Company are sold to an underwriter for distribution to

      2.    Registrations.

            (a)   [Intentionally Omitted].

            (b)   Piggyback Registration. Each time the Company decides to file
      a Registration Statement under the Securities Act (other than the
      Registration Statement on Form S-1 the Company originally filed with the
      SEC on March 9, 2004, as amended from time to time thereafter, and other
      than on Forms S-4 or S-8 or any successor form for the registration of
      securities issued or to be issued in connection with a merger or
      acquisition or employee benefit plan), the Company shall give written
      notice thereof to the Holders. The Company shall include in such
      Registration Statement such shares of Registrable

                                       2
<PAGE>

      Securities for which it has received written requests to register such
      shares within 30 days after such written notice has been given. If in the
      good faith judgment of the managing underwriter in any Underwritten
      Offering, the inclusion of all of the shares of Registrable Securities and
      any other Common Stock requested to be registered by third parties holding
      similar registration rights would interfere with the successful marketing
      of a smaller number of such shares, then the number of shares of
      Registrable Securities and other Common Stock to be included in the
      offering (except for shares to be issued by the Company in an offering
      initiated by the Company) shall be reduced as provided herein. The Company
      shall advise all holders of securities requesting registration of the
      underwriters' decision, and the number of shares of securities that are
      entitled to be included in the Underwritten Registration shall be
      allocated first to the Company for securities being sold for its own
      account and thereafter as set forth in paragraph (c) below. If any person
      does not agree to the terms of any such underwriting, he shall be excluded
      therefrom by written notice from the Company or the underwriter. Any
      Registrable Securities or other securities excluded or withdrawn from such
      underwriting shall be withdrawn from such registration. If shares are so
      withdrawn from the registration or if the number of shares of Registrable
      Securities to be included in such registration was previously reduced as a
      result of marketing factors, the Company shall then offer to all persons
      who have retained the right to include securities in the registration the
      right to include additional securities in the registration in an aggregate
      amount equal to the number of shares so withdrawn, with such shares to be
      allocated among the persons, requesting additional inclusion in accordance
      with paragraph (c) below.

            (c)   In any circumstance in which all of the Registrable Securities
      and other shares of Common Stock of the Company (including shares of
      Common Stock issued or issuable upon conversion of shares of any currently
      unissued series of preferred stock of the Company) with registration
      rights (the "Other Shares") requested to be included in a registration on
      behalf of the Holders or other selling stockholders cannot be so included
      as a result of limitations of the aggregate number of shares of
      Registrable Securities and Other Shares that may be so included, the
      number of shares of Registrable Securities and Other Shares that may be so
      included shall be allocated among the Holders and other selling
      stockholders requesting inclusion of shares pro rata on the basis of the
      number of shares Registrable Securities and Other Shares that would be
      held by such Holders and other selling stockholders, assuming conversion.
      If any Holder or other selling stockholder does not request inclusion of
      the maximum number of shares of Registrable Securities and Other Shares
      allocated to him pursuant to the above-described procedure, the remaining
      portion of his allocation shall be reallocated among those requesting
      Holders and other selling stockholders whose allocations did not satisfy
      their requests pro rata on the basis of the number of Registrable
      Securities and Other Shares which would be held by such Holders and other
      selling stockholders, assuming conversion, and this procedure shall be
      repeated until all of the shares of Registrable Securities and Other
      Shares which may be included in the registration on behalf of Holders and
      other selling stockholders have been so allocated.

      3.    Registration Procedures. If and whenever the Company is required to
register Registrable Securities, the Company will use its best efforts to effect
such registration to permit

                                       3
<PAGE>

the sale of such Registrable Securities in accordance with the intended plan of
distribution thereof, and pursuant thereto the Company will as expeditiously as
possible:

            (a)   prepare and file with the SEC as soon as practicable a
      Registration Statement with respect to such Registrable Securities and use
      its best efforts to cause such Registration Statement to become effective
      and remain effective until the Registrable Securities covered by such
      Registration Statement have been sold;

            (b)   prepare and file with the SEC such amendments and
      post-effective amendments to the Registration Statement, and such
      supplements to the Prospectus, as may be requested by the Holders or any
      underwriter of Registrable Securities or as may be required by the rules,
      regulations or instructions applicable to the registration form used by
      the Company or by the Securities Act or rules and regulations thereunder
      to keep the Registration Statement effective until all Registrable
      Securities covered by such Registration Statement are sold in accordance
      with the intended plan of distribution set forth in such Registration
      Statement or supplement to the Prospectus;

            (c)   deliver to the Holders and the underwriters, if any, without
      charge, as many copies of each Prospectus (and each preliminary
      prospectus) as such Persons may reasonably request (the Company hereby
      consenting to the use of each such Prospectus (or preliminary prospectus)
      by the selling Holders and the underwriters, if any, in connection with
      the offering and sale of the Registrable Securities covered by such
      Prospectus (or preliminary prospectus) and a reasonable number of copies
      of the then-effective Registration Statement and any post-effective
      amendments thereto and any supplements to the Prospectus, including
      financial statements and schedules, all documents incorporated therein by
      reference and all exhibits (including those incorporated by reference);

            (d)   prior to any public offering of Registrable Securities,
      register or qualify or cooperate with the Holders, the underwriters, if
      any, and their respective counsel in connection with the registration or
      qualification of such Registrable Securities for offer and sale under the
      securities or blue sky laws of such jurisdictions as such selling Holders
      or underwriters may designate in writing and do anything else necessary or
      advisable to enable the disposition in such jurisdictions of the
      Registrable Securities covered by the Registration Statement; provided
      that the Company shall not be required to qualify generally to do business
      in any jurisdiction where it is not then so qualified or to take any
      action which would subject it to general service of process in any such
      jurisdiction where it is not then so subject;

            (e)   cause all such Registrable Securities to be listed on each
      securities exchange or automated quotation system on which similar
      securities issued by the Company are then listed;

            (f)   provide a transfer agent and registrar for all such
      Registrable Securities not later than the effective date of such
      Registration Statement;

                                       4
<PAGE>

            (g)   advise each seller of such Registrable Securities, promptly
      after it shall receive notice or obtain knowledge thereof, of the issuance
      of any stop order by the SEC suspending the effectiveness of such
      Registration Statement or the initiation or threatening of any proceeding
      for such purpose and promptly use its reasonable best efforts to prevent
      the issuance of any stop order or to obtain its withdrawal if such stop
      order should be issued;

            (h)   at least three days prior to the filing of any Registration
      Statement or prospectus or any amendment or supplement to such
      Registration Statement or prospectus or any document that is to be
      incorporated by reference into such Registration Statement or prospectus,
      furnish a copy thereof to each seller of such Registrable Securities or
      their counsel;

            (i)   notify the Holders at any time when a prospectus relating to
      such Registration Statement is required to be delivered under the
      Securities Act, of the happening of any event as a result of which the
      prospectus included in such Registration Statement, as then in effect,
      includes a Misstatement, and then to correct such Misstatement as set
      forth in Section 7; and

            (j)   permit a representative of the Holders, the underwriters, if
      any, and any attorney or accountant retained by such Holders or
      underwriter to participate, at each such Person's own expense, in the
      preparation of the Registration Statement, and cause the Company's
      officers, directors and employees to supply all information reasonably
      requested by any such representative, underwriter, attorney or accountant
      in connection with the Registration; provided, however, that such
      representatives, underwriters, attorneys or accountants enter into a
      confidentiality agreement, in form and substance reasonably satisfactory
      to the Company, prior to the release or disclosure of any such
      information.

      4.    Registration Expenses. The Registration Expenses of all
Registrations shall be borne by the Company. It is acknowledged by the Holders
that the Holders will bear all incremental selling expenses relating to the sale
of the Registrable Securities, such as underwriters' commissions and discounts,
brokerage fees, underwriter marketing costs and fees and expenses of counsel to
the Holders.

      5.    Requirements for Participation in Underwritten Offerings. No person
may participate in any Underwritten Offering for equity securities of the
Company pursuant to a Registration initiated by the Company hereunder unless
such Person (a) agrees to sell such Person's securities on the basis provided in
any underwriting arrangements approved by the Company and (b) completes and
executes all questionnaires, powers of attorney, indemnities, lock-up
agreements, underwriting agreements and other documents required under the terms
of such underwriting arrangements.

      6.    Indemnification.

            (a)   The Company agrees to indemnify, to the extent permitted by
      law, the holder of Registrable Securities, its officers and directors and
      each Person who controls

                                       5
<PAGE>

      such holder (within the meaning of the Securities Act) against all losses,
      claims, damages, liabilities and expenses (including attorneys' fees)
      caused by any untrue or alleged untrue statement of material fact
      contained in any Registration Statement, prospectus or preliminary
      prospectus or any amendment thereof or supplement thereto or any omission
      or alleged omission of a material fact required to be stated therein or
      necessary to make the statements therein not misleading, except insofar as
      the same are caused by or contained in any information furnished in
      writing to the Company by such holder expressly for use therein or by such
      holder's failure to deliver a copy of the Registration Statement or
      prospectus or any amendments or supplements thereto after the Company has
      furnished such holder with a sufficient number of copies of the same. The
      Company will indemnify the underwriters, their officers and directors and
      each Person who controls such underwriters (within the meaning of the
      Securities Act) to the same extent as provided above with respect to the
      indemnification of the holder.

            (b)   In connection with any Registration Statement in which a
      holder of Registrable Securities is participating, such holder will
      furnish to the Company in writing such information and affidavits as the
      Company reasonably requests for use in connection with any such
      Registration Statement or prospectus and, to the extent permitted by law,
      will indemnify the Company, its directors and officers and agents and each
      Person who controls the Company (within the meaning of the Securities Act)
      against any losses, claims, damages, liabilities and expenses (including
      without limitation reasonable attorneys' fees) resulting from any untrue
      statement of material fact contained in the Registration Statement,
      prospectus or preliminary prospectus or any amendment thereof or
      supplement thereto or any omission of a material fact required to be
      stated therein or necessary to make the statements therein not misleading,
      but only to the extent that such untrue statement or omission is contained
      in any information or affidavit so furnished in writing by such holder
      expressly for use therein; provided that the obligation to indemnify will
      be several, not joint and several, among such holders of Registrable
      Securities, and the liability of each such holder of Registrable
      Securities will be in proportion to and limited to the gross amount
      received by such holder from the sale or Registrable Securities pursuant
      to such Registration Statement. The holders of Registrable Securities will
      indemnify the underwriters, their officers, directors and each Person who
      controls such underwriters (within the meaning of the Securities Act) to
      the same extent as provided above with respect to indemnification of the
      Company.

            (c)   Any person entitled to indemnification herein will (i) give
      prompt written notice to the indemnifying party of any claim with respect
      to which it seeks indemnification and (ii) unless in such indemnified
      party's reasonable judgment a conflict of interest between such
      indemnified and indemnifying parties may exist with respect to such claim,
      permit such indemnifying party to assume the defense of such claim with
      counsel reasonably satisfactory to the indemnified party. If such defense
      is assumed, the indemnifying party will not be subject to any liability
      for any settlement made by the indemnified party without its consent (but
      such consent will not be unreasonably withheld). An indemnifying party who
      is not entitled to, or elects not to, assume the defense of a claim will
      not be obligated to pay the fees and expenses of more than one counsel for
      all parties indemnified by such indemnifying party with respect to such
      claim, unless in the reasonable judgment of any indemnified party a
      conflict of

                                       6
<PAGE>

      interest may exist between such indemnified party and any other of such
      indemnified parties with respect to such claim.

            (d)   The indemnification provided for under this Agreement will
      remain in full force and effect regardless of any investigation made by or
      on behalf of the indemnified party or any officer, director or controlling
      person of such indemnified party and will survive the transfer of
      securities. The Company and each holder of Registrable Securities
      participating in the offering also agrees to make such provisions as are
      reasonably requested by any indemnified party for contribution to such
      party in the event the Company's or such holder's indemnification is
      unavailable for any reason.

            (e)   Notwithstanding the foregoing, to the extent that the
      provisions on indemnification and contribution contained in the
      underwriting agreement entered into in connection with an Underwritten
      Offering are in conflict with the foregoing provisions, the provisions of
      the underwriting agreement shall control.

      7.    Suspension of Sales. Upon receipt of written notice from the Company
that a Registration Statement or Prospectus contains a Misstatement, each of the
Holders shall forthwith discontinue disposition of Registrable Securities until
it has received copies of a supplemented or amended Prospectus correcting the
Misstatement (it being understood that the Company hereby covenants to prepare
and file such supplement or amendment as soon as practicable after the time of
such notice), or until it is advised in writing by the Company that the use of
the Prospectus may be resumed.

      8.    Termination of Prior Registration Rights Agreements. Each of the
parties to this Agreement hereby agrees that, upon the effectiveness of this
Agreement, that certain Registration Rights Agreement, dated as of January 20,
1999, by and among Waste Corporation of America, Inc., WCA Partners, L. P. and
EFO Co-Investment Partners, and that certain Registration Rights Agreement,
dated as of September 28, 2000, by and between Waste Corporation of America,
Inc. and WCA Partners, L.P., are terminated, and no party to either such
registration rights agreement shall thereafter have any further rights or
obligations with respect to such registration rights agreements.

      9.    Miscellaneous.

            (a)   Notices. All notices and other communications provided for or
      permitted hereunder shall be made in accordance with the notice provisions
      contained in the Purchase Agreement.

            (b)   Successors and Assigns. This Agreement shall inure to the
      benefit of and be binding upon the successors and assigns of the Company.
      No rights under this Agreement may be assigned by any Holder without the
      prior written consent of the Company.

            (c)   Counterparts. This Agreement may be executed in any number of
      counterparts and by the parties hereto in separate counterparts, each of
      which when so executed shall be deemed to be an original and all of which
      taken together shall constitute one and the same agreement.

                                       7
<PAGE>

            (d)   Governing Law. This Agreement shall be governed by and
      construed in accordance with the laws of the State of Texas.

            (e)   Amendment. This Agreement may be amended only by a written
      instrument executed by the Company and Holders who hold a majority of the
      Registrable Securities.

            (f)   Termination. This Agreement shall terminate and the
      registration rights granted hereunder shall expire on the date that is
      four (4) years and six (6) months after the effective date of the
      Company's IPO; provided that such termination and expiration shall not
      affect registration rights exercised prior to such date.

                                       8

      IN WITNESS WHEREOF, the parties have executed this Agreement as of the
date first written above.
