               AMENDED AND RESTATED REVOLVING CREDIT AND TERM LOAN
                                    AGREEMENT

     Reference is made to that AMENDED AND RESTATED REVOLVING CREDIT AND TERM
LOAN AGREEMENT (as amended and in effect from time to time, the "Credit
Agreement") dated as of the 22nd day of October, 2003, by and among WASTE
CONNECTIONS, INC., a Delaware corporation (the "Parent"), its Subsidiaries
(together with the Parent, collectively the "Borrowers"), such banks or other
financial institutions which may become a party thereto (the "Lenders"), and
FLEET NATIONAL BANK as Administrative Agent for the Lenders (the "Administrative
Agent"). Capitalized terms used herein without definition shall have the
respective meanings set forth in the Credit Agreement.

     WHEREAS, pursuant to the Credit Agreement, the original Term Loan Lenders
(the "Original Term Loan Lenders") made a term loan to the Borrowers in the
original principal amount of $175,000,000 (the "Original Term Loan");

     WHEREAS, the Borrowers wish to refinance the Original Term Loan in full
from the proceeds of a Refinancing Term Loan in the aggregate principal amount
of $200,000,000; and

     WHEREAS, the Borrowers have requested that the Refinancing Term Loan
Lenders and the Administrative Agent enter into this Refinancing Facility
Amendment in accordance with the terms of ss.4.7 of the Credit Agreement as set
forth herein (hereafter, this "Amendment");

     NOW, THEREFORE, in consideration of the foregoing, and for other good and
valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties hereby agree as follows:

     ss.1. REFINANCING TERM LOAN.

     (a)  Subject to the terms and conditions set forth herein, each of the
          undersigned financial institutions identified on the signature pages
          hereto as a "Refinancing Term Loan Lender" (individually, a
          "Refinancing Term Loan Lender" and collectively, the "Refinancing Term
          Loan Lenders") agrees to lend to the Borrowers on the Effective Date
          (defined below) that amount set forth opposite its signature hereto of
          the Refinancing Term Loan, which shall be in the aggregate principal
          amount of $200,000,000. For the avoidance of doubt, each of the
          Refinancing Term Loan Lenders hereby acknowledges and agrees that on
          the Effective Date that portion of such Refinancing Term Loan Lender's
          Original Term Loan which is in an amount equal to or less than the
          amount set forth opposite such Refinancing Term Loan Lender's
          signature hereto of the Refinancing Term Loan shall be deemed to have
          been repaid in full and automatically, without any action on the part
          of any Person, deemed to have been readvanced in an identical equal
          amount, with such readvanced amount constituting such Refinancing Term
          Loan Lender's Refinancing Term Loan. Upon the request and at the
          direction of the Administrative Agent, each of the Refinancing Term
          Loan Lenders hereby agrees to make any necessary wire transfers to
          such other Term Loan Lenders as directed by the Administrative Agent
          in order for each Refinancing Term Loan Lender's portion of the
          Refinancing Term Loan to be consistent with that amount set forth
          opposite its signature hereto.
<PAGE>
     (b)  Upon payment of the Original Term Loan (the "March 2004 Prepayment"),
          the Refinancing Term Loan shall be thereafter the "Term Loan" referred
          to and as defined in the Credit Agreement, shall constitute an
          Obligation of the Borrowers, shall amortize on the schedule and be
          subject to the mandatory and optional prepayment provisions as set
          forth in ss.4 of the Credit Agreement for the Term Loan, and the
          outstanding principal amount thereof shall be due and payable on the
          Term Loan Maturity Date. The Refinancing Term Loan shall bear interest
          from and after the Effective Date as set forth in ss.4.6 of the Credit
          Agreement (as amended by this Amendment). The Borrowers jointly and
          severally promise to pay to the Administrative Agent for the account
          of the Refinancing Term Loan Lenders the principal of and interest on
          the Refinancing Term Loan in accordance with the provisions of ss.4 of
          the Credit Agreement (as amended by this Amendment).

     (c)  Immediately following the March 2004 Prepayment (i) the Credit
          Agreement shall be amended in accordance with the provisions of
          ss.ss.2 through 4 below, (ii) all references in the Credit Agreement
          and the other Loan Documents to the words "Term Loan" shall be deemed
          to be references to or to relate to the Refinancing Term Loan advanced
          pursuant to this ss.1, (iii) the Refinancing Term Loan shall be
          governed by and subject to all of the provisions, terms and conditions
          set forth in the Credit Agreement and the other Loan Documents in
          every respect as though such Refinancing Term Loan had been originally
          referred to therein as the "Term Loan", and (iv) thereafter the
          Refinancing Term Loan shall be referred to as the Term Loan. In
          furtherance of and not in limitation of the foregoing, and
          notwithstanding anything to the contrary contained herein, the
          amendments effected by the provisions of ss.ss.2 through 4 below shall
          only be applicable to the Refinancing Term Loan and shall not be
          applicable to the Original Term Loan.

     (d)  Each Refinancing Term Loan Lender, by execution of this Amendment,
          hereby agrees to be bound by, and shall be entitled to the benefits
          of, all of the terms, conditions and provisions of the Credit
          Agreement applicable to the Term Loan Lenders as if such Refinancing
          Term Loan Lender had been one of the lending institutions originally
          executing the Credit Agreement as a "Term Loan Lender"; provided that
          nothing herein shall be construed as making any Refinancing Term Loan
          Lender liable to the Borrowers or the other Lenders in respect of any
          acts or omissions of any party to the Credit Agreement or in respect
          of any other event occurring prior to the Effective Date (except where
          such Refinancing Term Loan Lender was also an Original Term Loan
          Lender). Each Refinancing Term Loan Lender (a) represents and warrants
          that (i) it is duly and legally authorized to enter into this
          Amendment, (ii) the execution, delivery and performance of this
          Amendment does not conflict with any provision of law or of the
          charter or by-laws of the Refinancing Term Loan Lender, or of any
          agreement binding on the Refinancing Term Loan Lender, (iii) all acts,
          conditions and things required to be done and performed and to have
          occurred prior to the execution, delivery and performance of this
          Amendment, and to render the same the legal, valid and binding
          obligation of the Refinancing Term Loan Lender, enforceable against it
          in accordance with its terms, have been done and performed and have
          occurred in due and strict compliance with all applicable laws; (b)
          confirms that it has received a copy of the Credit Agreement and the
          Loan Documents, together with copies of the most recent financial
          statements delivered pursuant toss.ss.6.4 and 7.4 thereof and such
          other documents and information as it has deemed appropriate to make
          its own credit analysis and decision to enter into this Amendment; (c)
          agrees that it will, independently and without reliance upon the other
          Lenders or the Administrative Agent and based on such documents and
          information as it shall deem appropriate at the time, continue to make
          its own credit decisions in taking or not taking action under the

                                       -2-
<PAGE>
          Credit Agreement; (d) represents and warrants that it is eligible to
          become a party to the Credit Agreement under the terms and conditions
          of the Credit Agreement as amended hereby; (e) appoints and authorizes
          the Administrative Agent to take such action on its behalf and to
          exercise such powers under the Credit Agreement and the other Loan
          Documents as are delegated to the Administrative Agent by the terms
          thereof, together with such powers as are reasonably incidental
          thereto; and (f) agrees that it will perform in accordance with their
          terms all of the obligations which by the terms of the Credit
          Agreement are required to be performed by it as a Term Loan Lender.

     (e)  The Borrowers shall, within five (5) days after a request by a
          Refinancing Term Loan Lender to the Administrative Agent, deliver to
          each such requesting Refinancing Term Loan Lender a Term Note
          evidencing such Refinancing Term Loan Lender's portion of the Term
          Loan.

     SS.2. AMENDMENT TOSS.4.5 OF THE CREDIT AGREEMENT. Section 4.5 of the Credit
Agreement is hereby amended by inserting the following sentence at the end of
such section:

          "Notwithstanding anything to the contrary above, if the Borrowers

          Loan made pursuant ss.4.7, the Borrowers shall pay a premium with

          prepaid."

          during such Interest Period at the Base Rate plus 0.25%."

          "(b) To the extent that all or any portion of the Refinancing Term
          Loan bears interest during such Interest Period at the Eurodollar

          interest during such Interest Period at the rate per annum equal to
          the Eurodollar Rate plus 1.75%."

Credit Agreement to reflect each Refinancing Term Loan Lender's Term Loan

upon the date each of the following conditions precedent is satisfied (the
