IN WITNESS WHEREOF, the Company and Haddrill have duly executed this Eighth Amendment as of the date first above written.

Schedule A-8

ADDITIONAL RESTRICTED STOCK UNITS

1.                                       The number of shares of common stock subject to the Additional Restricted Stock Units was determined by dividing $4.0 million dollars by the average per share closing price of the Company’s common stock on the stock exchange in which the stock is principally traded for the 20 business days immediately prior to the date of the grant (the “Average Price”).

2.                                       The Additional Restricted Stock Units shall vest: (i) with respect to a number of Additional Restricted Stock Units determined by dividing $2.5 million dollars by the Average Price, in four equal installments on each of February 15, 2011, May 15, 2011, August 15, 2011, and November 15, 2011, and (ii) with respect to a number of Additional Restricted Stock Units determined by dividing $1.5 million dollars by the Average Price, in full on July 1, 2012, so long as Haddrill remains in continuous service with the Company through such date.

3.                                       If Haddrill’s employment with the Company is terminated under paragraphs 7(b) or 7(c) of the Employment Agreement, in addition to the other compensation and benefits provided under the Employment Agreement, the vesting of the Additional Restricted Stock Units will accelerate in full as of the termination date.

4.                                       In addition to the above, notwithstanding any provision of the Employment Agreement, or the Plan to the contrary, in the event of a Change of Control (as defined in the Employment Agreement), the Additional Restricted Stock Units shall become immediately and fully vested and exercisable effective as of immediately prior to such Change of Control.

5.                                       Each vested Additional Restricted Stock Unit represents Haddrill’s right to receive one share of the Company’s common stock on the applicable vesting date (subject to the terms and conditions of the Plan, including the satisfaction of any tax withholding obligations).

6.                                       Except as described in this Schedule A-8, upon a termination of Haddrill’s service with the Company (or any successor) for any reason, the unvested portion of the Additional Restricted Stock Units granted hereunder at the time of such termination of service (after giving effect to the accelerated vesting, if any, described in this Schedule A-8, if any) shall be forfeited effective as of the date of termination.
