#### Forward Looking Statements
Statements in this release that are not historical are forward-looking statements within the meaning of the U.S. Private Securities Litigation Reform Act of 1995. These forward-looking statements, which are subject to known and unknown risks, uncertainties and assumptions about us, may include, without limitation, statements regarding the intended conduct, timing and terms of the proposed Notes offering and any future actions by us in respect of the Notes offering. These statements are only predictions based on our current expectations and projections about future events. There are important factors that could cause our actual results to differ materially from those expressed or implied by the forward-looking statements. Significant risks and uncertainties may relate to, but are not limited to, macroeconomic conditions; policy changes affecting international trade, including import/export restrictions and tariffs; inflationary pressures and energy costs; currency movements; political instability, including the ongoing conflicts in Eastern Europe and the Middle East and any expansion of such conflicts, and other geopolitical events; supply chain disruptions; market conditions and price volatility for titanium dioxide, zircon and other feedstock materials, as well as global and regional economic downturns, that adversely affect the demand for our end-use products; disruptions in production at our mining and manufacturing facilities; and other financial, economic, competitive, environmental, political, legal and regulatory factors. These and other risk factors are discussed in the Company's filings with the Securities and Exchange Commission.

Moreover, we operate in a very competitive and rapidly changing environment. New risks and uncertainties emerge from time to time, and it is not possible for our management to predict all risks and uncertainties, nor can management assess the impact of all factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements. Although we believe the expectations reflected in the forward-looking statements are reasonable, we cannot guarantee future results, level of activity, performance, synergies or achievements. Neither we nor any other person assumes responsibility for the accuracy or completeness of any of these forward-looking statements. You should not rely upon forward-looking statements as predictions of future events. Unless otherwise required by applicable laws, we undertake no obligation to update or revise any forward-looking statements, whether because of new information or future developments.
