report 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>
