Filing notes and footnotes

Explanation of responses 1 footnote

Footnote F1

The Reporting Person elected to receive stock options in lieu of the quarterly cash payment he would normally receive as a Nabors director. The number of options was determined by dividing the foregone cash payment of $37,500 by the option price on the date of grant calculated in accordance with the Black-Scholes valuation model, or $35.51 per share. The options are fully vested as of the date of grant, and have an exercise price of $78.12 per share, which is the market price of Nabors' common shares on the date of grant.
