On December 31, 2015, Nabors Industries Ltd. (the “Company”) and Nabors Industries, Inc. (“Nabors Delaware”) entered into a third amendment to the executive employment agreement with Anthony G. Petrello, Chairman, President and Chief Executive Officer of each of the Company and Nabors Delaware, effective as of January 1, 2013 (the “Petrello Employment Agreement”). This amendment extends the 10% reduction in the annual rate of base salary payable under the Petrello Employment Agreement from $1.75 million per year to $1.575 million per year through June 30, 2016.

On December 31, 2015, the Company and Nabors Delaware entered into a third amendment to the executive employment agreement with William Restrepo, Chief Financial Officer of each of the Company and Nabors Delaware, effective as of March 3, 2014 (the “Restrepo Employment Agreement”). This amendment extends the 10% reduction in the annual rate of base salary payable under the Restrepo Employment Agreement from $650,000 per year to $585,000 per year through June 30, 2016.

The reduction in base salaries of Messrs. Petrello and Restrepo was initially implemented in December 2014 for an interim 6-month period commencing January 1, 2015 and ending June 30, 2015 pursuant to a first amendment to the employment agreements, and was further extended for an additional 6-month period ending December 31, 2015 pursuant to a second amendment to the employment agreements, as part of an initiative to reduce costs in light of the decline in industry conditions. The salary reductions do not affect the calculation or payment of any ancillary benefits. The Petrello Employment Agreement and the Restrepo Employment Agreement were filed as Exhibit 99.1 to our Form 8-K, dated March 7, 2013 and Exhibit 10.1 to our Form 8-K, dated March 3, 2014, respectively. The first amendment to the Petrello Employment Agreement and the first amendment to the Restrepo Employment Agreement were filed as Exhibit 99.1 and Exhibit 99.2, respectively, to our Form 8-K, filed on December 19, 2014. The second amendment to the Petrello Employment Agreement and the second amendment to the Restrepo Employment Agreement were filed as Exhibit 99.1 and Exhibit 99.2, respectively, to our Form 8-K, filed on June 8, 2015.

The foregoing descriptions of the third amendments are qualified in their entirety by reference to such amendments, which are attached hereto as Exhibit 99.1 for the Petrello Employment Agreement and Exhibit 99.2 for the Restrepo Employment Agreement and are incorporated by reference herein.
