                                EXPLANATORY NOTE


         Nabors Industries Ltd. (the "Company") is furnishing this Current
Report on Form 8-K/A to include certain supplemental historical financial
information in segment reporting format previously furnished in the Current
Report on Form 8-K dated July 29, 2003 (the "Original 8-K").

         The Company presented its adjusted cash flow derived from operating
activities and adjusted income derived from operating activities for all
quarterly and annual periods presented in the Original 8-K. The components of
adjusted cash flow derived from operating activities and adjusted income derived
from operating activities are computed using amounts determined in accordance
with accounting principles generally accepted in the United States of America
("GAAP"). Adjusted cash flow derived from operating activities is computed by:
subtracting direct costs and general and administrative expenses from Operating
revenues and then adding Earnings from unconsolidated affiliates. Adjusted
income derived from operating activities is computed by: subtracting direct
costs, general and administrative expenses, and depreciation and amortization
expense from Operating revenues and then adding Earnings from unconsolidated
affiliates.

         As part of this Current Report on Form 8-K/A, we have provided a
reconciliation, for all quarterly and annual periods presented in the Original
8-K, of adjusted cash flow derived from operating activities and adjusted income
derived from operating activities, which are "non-GAAP" financial measures under
Regulation G, to net cash provided by operating activities from our consolidated
statements of cash flows and consolidated income before income taxes,
respectively, which are the most comparable GAAP financial measures. This
Current Report on Form 8-K/A amends, restates and supercedes the Original 8-K in
its entirety.

         The Company included its adjusted cash flow derived from operating
activities and adjusted income derived from operating activities in the Original
8-K because management evaluates the performance of its business units and the
consolidated Company based on several criteria, including adjusted cash flow
derived from operating activities and adjusted income derived from operating
activities, and because it believes these financial measures are an accurate
reflection of the ongoing profitability of the Company.
