Attachment A

The provisions of this Attachment A shall determine the extent, if any, that the awarded Performance Units become earned and payable.

1. Performance Period. The Performance Period shall be the period beginning July 1, 2006 and ending June 30, 2009. In the event of a Corporate Change, the Performance Period shall be the period beginning on July 1,
2006 and ending on the date of the Corporate Change.

2. Total Return to Shareholders (TRS). The payment of a Performance Unit will be
determined based on the comparison of the TRS (as defined below) of the Companys common stock for the Performance Period relative to the TRS of each of the common stocks of the Peer Group for the Performance Period. TRS shall be determined by
calculating the value of $100 invested in Company common stock on the first day of the Performance Period, with dividends reinvested, compared to $100 invested in each of the Peer Group companies, with dividend reinvestment, during the same period.
The TRS will be measured for the Company and the peer group companies from the first to the last trading day of the Performance Period. Notwithstanding the foregoing, no payment shall be made unless the Company has a TSR of at least 5.21 % (the
3-year U.S. Treasury bill rate as of June 30, 2006) for the Performance Period.

3. Peer Group. The Peer Group companies will be the companies
comprising the Philadelphia Stock Exchanges Oil Service Sector Index (or its successor) on the last trading day of the Performance Period.

4.
Performance Standards and Awards Paid. For the Performance Units to be earned and payable, the Companys TSR at the end of the Performance Period must equal or exceed a relative threshold of 40% compared to the Peer Group companies. At
the threshold, 50% of the Performance Units awarded shall be earned. The Committee has established a target performance level at which the Companys TSR at the end of the Performance Period would equal or exceed a relative threshold of 50%
compared to the Peer Group companies, at which 100% of the Performance Units awarded shall be earned. The Committee has established a maximum performance level at which the Companys TSR at the end of the Performance Period would equal or
exceed a relative threshold of 75% compared to the Peer Group companies, at which 200% of the Performance Units awarded shall be earned. Awards earned will be calculated using straight-line interpolation for performance between the threshold and
target performance levels and the target and maximum performance levels. The maximum amount of compensation that may be paid under all performance awards paid in cash to any one individual during any calendar year may not exceed $5 million.

The following table illustrates certain performance/payout relationships for the Performance Units.
