This Amendment (the "Amendment") and the attached Schedule A are entered into as
of the 30th day of April, 2001 by Del Webb Corporation, a Delaware corporation
(the "Company"), and Anne L. Mariucci. To the extent there is any actual or
apparent conflict between this Amendment and the terms of the Employment
Agreement, this Amendment shall prevail.

Whereas, Company and the Employee desire to amend the Agreement in certain
respects;

Now therefore, the Agreement is hereby amended as follows:

         Section 2 of the Agreement is hereby amended as follows:

         "(e) Merger with Pulte Corporation. Notwithstanding anything in this
         Agreement to the contrary, upon the effective date of the merger of
         Company and Pulte Acquisition Corp. pursuant to the merger agreement
         dated April 30, 2001 (the "Merger Effective Date") between Company,
         Pulte Corporation and Pulte Acquisition Corporation, Employee will, at
         her election, either continue as an at will employee of Company or
         become a consultant to Company for the period (the "Post-Merger
         Period") beginning on the Merger Effective Date and continuing until
         the first to occur of (1) the first anniversary of the Merger Effective
         Date and (2) termination of the Employee's employment or consulting
         arrangement because of Employee's death or disability, or termination
         by Company (if Company terminates, she will automatically become a
         consultant for the remainder of the one-year period following the
         Merger Effective Date). If Employee elects to continue as an Employee,
         she may, at any time during the Post-Merger Period, elect to cease
         being an employee and then must continue as a consultant, on an
         as-needed basis by Company (making herself available as reasonably
         requested by the Company) until the end of the Post-Merger Period. Once
         Employee elects to be a consultant, she may not return to employee
         status without the consent of Company."

         Section 11 is amended as follows:

         "For purposes of this Section, a Competing Business is defined as a
         business whose primary business is conventional homebuilding and/or
         age-restricted homebuilding. The Restrictive Covenant of this Section
         11 will continue until the end of the Post-Merger Period."

         Section 11 (a) (2) is amended as follows:

         "During the Post-Merger Period, directly or indirectly, for herself, or
         on behalf of, or in conjunction with, any other person or entity, seek
         or hire and/or hire any

         individual who is employed by Company and/or Pulte Acquisition Corp.,
         unless previously terminated by the Company and/or Pulte Acquisition
         Corp."

         Section 11 (f) is amended by the addition of the following at the end
thereof:

         "Notwithstanding the foregoing, if the Change-in-Control results from
         the merger of Company and Pulte Acquisition Corp. pursuant to the
         merger agreement described in Section 2(e) above, the restrictive
         covenant contained in this Section 11 will continue until the end of
         the Post-Merger Period."

Breach and Opportunity to Cure: No damages for any breach of the foregoing
provisions, including Schedule A, shall be available in the absence of providing
