This excerpt taken from the DUSA DEF 14A filed Apr 20, 2009.
SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE
Under the securities laws of the United States, the Companys directors, officers and any person holding more than ten percent (10%) of our Common Stock are required to report their ownership of securities and any changes in that ownership to the Securities and Exchange Commission on Forms 3, 4 and 5. Based on our review of the copies of such forms we have received, we believe that all of our officers, directors and shareholders holding ten percent (10%) or more of our Common Stock complied with all filing requirements applicable to them with respect to their reporting obligations. In making these statements, we have relied on the written representations of our directors and officers and copies of the reports that they and any person holding more than ten percent (10%) of our Common Stock have filed with the Securities and Exchange Commission.
