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

1.   Definitions

          (a)  The following definitions are hereby added to Section 1.01 of the
     Credit Agreement, in the correct alphabetical order, to read as follows:

          "Quoted Rate" has the meaning set forth in Section 2.01A(c)(ii).

   2
          "Quoted Rate Swing Line Loan" means a Swing Line Loan accruing
     interest at a Quoted Rate.

          (b)  The definition of "Base Rate Loans" in Section 1.01 of the
     Credit Agreement is amended in its entirety to read as follows:

          "Base Rate Loans" means the Revolving Loans and the Swing Line Loans
     accruing interest at the Base Rate.

          (c) The first sentence of the definition of "Interest Payment Date" in
     Section 1.01 of the Credit Agreement is amended in its entirety to read as
     follows:

          "Interest Payment Date" means (a) as to Base Rate Loans, the last day
     of each month, (b) as to Quoted Rate Swing Line Loans, the last day of the
     Interest Period for each Quoted Rate Swing Line Loan, (c) as to CD Rate
     Loans and Eurodollar Loans, the last day of each applicable Interest
     Period; provided that if the Interest Period for a Eurodollar Loan is
     greater than 3 months or the Interest Period for a CD Rate Loan is greater
     than 90 days, then the Interest Payment Date shall be the last day of each
     fiscal quarter of the Borrower and the last day of the applicable Interest
     Period and (d) as to Competitive Bid Loans, the last day of the Interest
     Period for each Competitive Bid Loan; provided that if the Interest Period
     on a Competitive Bid Loan is greater than 90 days then the Interest Payment
     Date shall be the last day of each fiscal quarter of the Borrower and the
     last day of the applicable Interest Period.

          (d)  The definition of "Interest Period" is amended by deleting the
     word "and" directly before subsection (c), by inserting a comma after the
     word "borrowing" directly before subsection (c) and by inserting the
     following subsection directly before the semicolon:

          and (d) with respect to Quoted Rate Swing Line Loans a period
     beginning on the date of advance and ending on the date specified in the
     respective Swing Line Loan Request, which shall not be more than 7 days in
     duration

2.   Amendment to Section 2.01A(c)(ii). Section 2.01A(c)(ii) of the Credit
     Agreement is amended in its entirety to read as follows:

              (ii) Swing Line Borrowings. By no later than 2:00 p.m. on the date
          of the requested borrowing of Swing Line Loans, the Borrower shall
          submit a Swing Line Loan Request to NationsBank setting forth (A) the
          amount of the requested Swing Line Loan (which shall not be less than
          $500,000 and in integral multiples of $500,000 in excess thereof), (B)
          the date of the requested Swing Line Loan and (C) whether such Swing
          Line Loan is to be a Base Rate Loan or a Quoted Rate Swing


                                        2
   3
          Line Loan and if it is a Quoted Rate Swing Line Loan, the
          applicable Interest Period and complying in all respects with Section
          5. If the Borrower has requested a Quoted Rate Swing Line Loan,
          NationsBank shall provide to the Borrower, no later than 2:30 p.m. on
          the date of the request, the rate at which NationsBank would be
          willing to provide such Swing Line Loan (the "Quoted Rate"). The
          Borrower shall notify NationsBank by 3:00 p.m. on such date whether it
          wishes to accept the Quoted Rate. Failure of the Borrower to timely
          accept the Quoted Rate shall make the Quoted Rate and the
          corresponding Swing Line Loan Request void.

3.   Amendment to Section 2.01A(c)(iii). The first three sentences and the last
     two sentences of Section 2.01A(c)(iii) of the Credit Agreement are amended
     in their entirety to read as follows:

               (iii) Additional Swing Line Loan Provisions. The Borrower agrees
          to repay all Swing Line Loans that are Base Rate Loans within one
          Business Day of demand therefor by NationsBank and all Swing Line
          Loans that are Quoted Rate Swing Line Loans at the end of the
          applicable Interest Period. Each repayment of a Swing Line Loan may be
          accomplished by requesting Revolving-A Loans in accordance with
          Section 2.02. In the event that the Borrower shall fail to repay any
          Swing Line Loan within three Business Days after demand therefor by
          NationsBank or the termination of the applicable Interest Period, and
          in any event upon (1) a request by NationsBank, (2) the occurrence of
          an Event of Default described in Section 9.01(f) or (3) the
          acceleration of any Loan or termination of any Commitment pursuant to
          Section 9.01, each other Lender shall irrevocably and unconditionally
          purchase from NationsBank, without recourse or warranty, an undivided
          interest and participation in such Swing Line Loan in an amount equal
          to such other Lender's Commitment Percentage thereof, by directly
          purchasing a participation in such Swing Line Loan in such amount
          (regardless of whether the conditions precedent thereto set forth in
          Section 5.02 hereof are then satisfied, whether or not the Borrower
          has made an Advance Request and whether or not the Revolving-A Loan
          Commitments are then in effect, any Event of Default exists or all the
          Loans have been accelerated) and paying the proceeds thereof to
          NationsBank at the address provided in Section 11.01, or at such other
          address as NationsBank may designate, in Dollars and in immediately
          available funds; provided that a Lender is not required to purchase a
          participation in a Swing Line Loan that was made by NationsBank during
          the existence of a Default or an Event of Default that was known to
          exist by NationsBank when it made such Swing Line Loan.




          Upon the purchase of a participation in respect of such Swing Line
          Loan by a Lender pursuant to this Section 2.01A(c), the amount so
          funded by the purchasing


                                       3
   4
          Lender shall become a Revolving-A Loan accruing interest at the Base
          Rate and shall no longer be a Swing Line Loan. On the date that the
          Lenders are required to purchase participations in Swing Line Loans
          under this Section 2.01A(c), NationsBank's pro rata share of such
          Swing Line Loans shall no longer be a Swing Line Loan hereunder but
          shall be a Revolving-A Loan accruing interest at the Base Rate.

4.   Amendment to Section 3.01(a)(ix). Section 3.01(a)(ix) of the Credit
     Agreement is amended in its entirety to read as follows:

                    (ix) All Swing Line Loans shall accrue interest at the Base
               Rate or if such Swing Line Loan is a Quoted Rate Swing Line Loan,
               then such Swing Line Loan shall accrue interest at the Quoted
               Rate applicable thereto.

5.   Amendment to Section 3.02(a). Section 3.02(a) of the Credit Agreement is
     amended in its entirety to read as follows:

               (a) Voluntary Prepayments. The Borrower shall have the right to
          prepay Loans in whole or in part from time to time without premium or
          penalty; provided, however, that (i) Eurodollar Loans and CD Rate
          Loans may only be prepaid on three Business Day' prior written notice
          to the Agent and any prepayment of Eurodollar Loans or CD Rate Loans
          will be subject to Section 4.01(d); (ii) each such partial prepayment
          of Loans shall be in the minimum principal amount of $1,000,000; and
          (iii) Competitive Bid Loans and Quoted Rate Swing Line Loans may not
          be prepaid unless a breakage fee equal to the amount of actual damages
          suffered by the Lender whose Competitive Bid Loan or Quoted Rate Swing
          Line Loan is prepaid is paid to such Lender; provided that such Lender
          shall provide the Borrower with the calculation of such damages.
          Amounts prepaid hereunder shall be applied as the Borrower may elect;
          provided, that if the Borrower fails to specify a voluntary prepayment
          then such prepayment shall be applied first to Revolving Loans that
          are Base Rate Loans, then to CD Rate Loans in direct order of Interest
          Period maturities, then to Eurodollar Loans in direct order of
          Interest Period maturities, then to Swing Line Loans (first to Swing
          Line Loans that are Base Rate Loans and then to Quoted Rate Swing Line
          Loans in direct order of Interest Period maturities) and then to
          Competitive Bid Loans pro rata among all Lenders holding same.

  6.      Amendment to Section 3.02(b). The last sentence of Section 3.02(b) of
          the Credit Agreement is amended in its entirety to read as follows:

               (b) Mandatory Prepayments. Any payments made under this Section
          3.02(b) shall be applied first to Revolving Loans that are Base Rate
          Loans, then to CD Rate Loans in direct order of Interest Period
          maturities, then to Eurodollar Loans in direct order

                                        4
   5
of Interest Period maturities, then to Swing Line Loans (first to Swing Line
Loans that are Base Rate Loans and then to Quoted Rate Swing Line Loans in
direct order of Interest Period maturities) and then to Competitive Bid Loans
pro rata among all Lenders holding same.

     its entirety and replaced by the new Exhibit 2.01A(c) attached hereto as

     effect on the financial condition of the Consolidated Pulte Group taken as
     a whole, (c) except as previously disclosed in its annual and quarterly
     filings with the Securities and Exchange Commission (none of which
     disclosed matters the Borrower deems to be material), there are no actions,
     suits or legal, equitable, arbitration or administrative proceedings
     pending or, to the knowledge of the Borrower, threatened against any member
     of the Consolidated Pulte Group which, if adversely determined, would
     likely have a material adverse effect on the financial or business
     condition of the Consolidated Pulte Group taken as a whole and (d) no
     Default or Event of Default exists and is continuing.
