                        end of the Performance Period and the determination of
                        the Company's Earnings Per Share Growth Rate (as defined

                        Period but before distribution of any shares pursuant to
                        this Award Agreement, the distribution of the shares

            5.    PERFORMANCE CRITERIA AND ADJUSTMENTS.

                  ADJUSTMENT OF BASE GRANT. The Base Grant will increase or
                  decrease based upon the Company's "Earnings Per Share Growth
                  Rate" as compared to the Earnings Per Share Growth Rate of the
                  Index during the Performance Period, as follows:



IF THE COMPANY'S EARNINGS PER SHARE COMPOUND GROWTH RATE              THE NUMBER OF
  OVER THE PERFORMANCE PERIOD AS COMPARED TO THE INDEX IS:       PERFORMANCE SHARES WILL BE:
- ----------------------------------------------------------       ---------------------------
                                                            
              ___th Percentile or Greater                           ___ X Base Grant
                    ___th Percentile                                ___ X Base Grant
                    ___th Percentile                                   Base Grant
                    ___th Percentile                                ___ X Base Grant
               Less than ___th Percentile                       [None / ___X Base Grant]


                        If intermediate percentiles are achieved, the number of
                  Performance Shares awarded will be prorated (partial shares
                  will be rounded down to the nearest whole share when
                  applicable). For example, if the Company's Earnings Per Share
                  Growth Rate during the Performance Period places the Company's
                  performance in the ___th percentile, then the number of
                  Performance Shares would be increased to ______ multiplied by
                  the Base Grant. In no event will Employee be entitled to
                  receive a number of Performance Shares greater than ___ times
                  the Base Grant, even if the Company's Earnings Per Share
                  Growth Rate during the Performance Period places the Company's
                  performance higher than the ____th percentile. Attachment B
                  provides a generic example of the operation of an award
                  granted under this Award Agreement.

            6.    EARNINGS PER SHARE GROWTH RATE. "Earnings Per Share Growth
                  Rate" for the Performance Period is the compounded
                  annual-growth rate (CAGR) of a company's earnings per share
                  from continuing operations, on a fully diluted basis, during
                  the Performance Period provided, however, that for purposes
                  of calculating the Company's Earnings Per Share Growth Rate,
                  SunCor Development Company's earnings from discontinued
                  operations will be considered earnings from continuing
                  operations for each fiscal year during the Performance
                  Period. Only those companies which were in the Index at both
                  the beginning and the ending of the Performance Period will be
                  considered. The



Page 3
Performance Share Agreement

                  Earnings Per Share Growth Rate of the companies in the Index
                  will be determined using an independent third party data
                  system. If the Index is discontinued, the Committee shall
                  select the most comparable index then in use for the sector
                  comparison. In addition, if the sector comparison is no longer
                  representative of the Company's industry or business, the
                  Committee shall replace the index with the most representative
                  index then in use. Once the CAGR of the Company and all
                  relevant companies in the Index have been determined, the
                  member companies will be ranked from greatest to least CAGR.
                  Percentiles will be calculated based on a company's relative
                  ranking. For example, company 1 out of 26 companies is given a
                  percentile of 96.2% (1.0 - 1/26). Percentiles will be carried
                  out to one (1) decimal place. If the Company is not in the
                  Index, then its percentile will be interpolated between the
                  companies listed in the relative ranking. These calculations
                  will be verified by the Company's internal auditors.

            7.    TERMINATION OF AWARD. This Award Agreement will terminate and
                  be of no further force or effect on the date that Employee is
                  no longer actively employed by the Company or any of its
                  subsidiaries, whether due to voluntary or involuntary
                  termination, death, retirement, disability, or otherwise.
                  Subject to Section 4, Employee will, however, be entitled to
                  receive any Common Stock and dividend equivalents payable
                  under Section 4 of this Award Agreement if Employee's
                  employment terminates after the Performance Period but before
                  Employee's receipt of such Common Stock and dividend
                  equivalents. For avoidance of doubt, no acceleration of
                  Performance Shares or the Performance Period will occur on a
                  change of control of the Company.

            8.    TAX WITHHOLDING. Employee must pay, or make arrangements
                  acceptable to the Company for the payment of any and all
                  federal, state, and local income and payroll tax withholding
                  that in the opinion of the Company is required by law. Unless
                  Employee satisfies any such tax withholding obligation by
                  paying the amount in cash or by check, the Company will
                  withhold shares of Common Stock having a Fair Market Value on
                  the date of withholding sufficient to cover the withholding
                  obligation.

            9.    NON-TRANSFERABILITY. Neither this award nor any rights under
                  this Award Agreement may be assigned, transferred, or in any
                  manner encumbered except by will or the laws of descent and
                  distribution, and any attempted assignment, transfer,
                  mortgage, pledge or encumbrance except as herein authorized,
                  will be void and of no effect.

            10.   DEFINITIONS: COPY OF PLAN AND PLAN PROSPECTUS. To the extent
                  not specifically defined in this Award Agreement, all
                  capitalized terms used in this Award Agreement will have the
                  same meanings ascribed to them in the Plan. By signing this
                  Award Agreement, Employee acknowledges receipt of a copy of
                  the Plan and the related Plan Prospectus.

            11.   CHOICE OF LAW. This Agreement will be governed by the laws of
                  the State of Arizona, excluding any conflicts or choice of law
                  rule or principle that might otherwise refer construction or
                  interpretation of this Agreement to another jurisdiction.

      An authorized representative of the Company has signed this Award
Agreement, and Employee has signed this Award Agreement to evidence Employee's
acceptance of the award on the terms specified in this Award Agreement, all as
of the Date of Grant.
