Implications of Being a Smaller Reporting Company

We are a “smaller reporting
company” meaning that the market value of our Common Stock held by non-affiliates is less than $250.0 million measured on the last
business day of our second fiscal quarter or our annual revenue is less than $100.0 million during the most recent completed fiscal year
and the market value of our Common Stock held by non-affiliates is less than $700.0 million measured on the last business day of our second
fiscal quarter. Accordingly, we may provide less public disclosure than larger public companies, including the inclusion of only two years
of audited financial statements and only two years of management’s discussion and analysis of financial condition and results of
operations disclosure. As a result, the information that we provide to our stockholders may be different than you might receive from other
public reporting companies in which you hold equity interests.
