ON FORWARD-LOOKING STATEMENTS
This
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’s current view and estimates of future

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 “anticipates,” “believes,” “estimates,” “expects,” “plans”
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

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.
