NPK International Inc.

In the ordinary course of conducting our business, we become involved in litigation and other claims from private party actions, as well as judicial and administrative proceedings involving governmental authorities at the federal, state, and local levels. In addition, in connection with the Sale Transaction, we have indemnified the Purchaser for certain pre-closing contingencies of the Fluids Systems business. While the outcome of litigation or other proceedings against us, including pre-closing contingencies of the Fluids Systems business, cannot be predicted with certainty, management does not expect that any loss resulting from such litigation or other proceedings, in excess of any amounts accrued or covered by insurance, will have a material adverse impact on our consolidated financial statements.
