This excerpt taken from the HPC DEF 14A filed Mar 21, 2007.
SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE
Section 16(a) of the Securities Exchange Act of 1934, as amended, requires our directors, executive officers and holders of more than ten percent (10%) of our common stock to file with the SEC and the New York Stock Exchange reports of beneficial ownership and changes in beneficial ownership of the common stock and other equity securities of Hercules within two (2) days of the changes. These persons are required by SEC rules to furnish Hercules with copies of all Section 16(a) forms they file.
Based solely on a review of the copies of those reports furnished to Hercules, we believe that, during 2006, our directors, executive officers and holders of more than ten percent of our common stock complied with all applicable Section 16(a) filing requirements.
