on Form 6-K may contain forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. These
statements are statements that are not historical facts, and are based on our management&rsquo;s current view and estimates of future
economic and other circumstances, industry conditions, company performance and financial results, including any potential or projected
impact of the geological event in Alagoas and related legal proceedings and of COVID-19 on our business, financial condition and operating
results. The words &ldquo;anticipates,&rdquo; &ldquo;believes,&rdquo; &ldquo;estimates,&rdquo; &ldquo;expects,&rdquo; &ldquo;plans&rdquo;
and similar expressions, as they relate to the company, are intended to identify forward-looking statements. Statements regarding the
potential outcome of legal and administrative proceedings, the implementation of principal operating and financing strategies and capital
expenditure plans, the direction of future operations and the factors or trends affecting our financial condition, liquidity or results
of operations are examples of forward-looking statements. Such statements reflect the current views of our management and are subject
to a number of risks and uncertainties, many of which are outside of the our control. There is no guarantee that the expected events,
trends or results will actually occur. The statements are based on many assumptions and factors, including general economic and market
conditions, industry conditions, and operating factors. Any changes in such assumptions or factors, including the projected impact of
the geological event in Alagoas and related legal proceedings and the unprecedented impact of COVID-19 pandemic on our business, employees,
service providers, stockholders, investors and other stakeholders, could cause actual results to differ materially from current expectations.
Please refer to our annual report on Form 20-F for the year ended December 31, 2019 filed with the SEC, as well as any subsequent filings
made by us pursuant to the Exchange Act, each of which is available on the SEC&rsquo;s website (www.sec.gov), for a full discussion of
the risks and other factors that may impact any forward-looking statements in this presentation.</P>
