The first two executives ensnared in the nation’s stock options scandal pleaded not guilty Wednesday in federal court to charges of making false statements to securities regulators, falsifying records and other charges.

Gregory Reyes, former chief executive of Brocade Communications Systems Inc. and Stephanie Jensen, Brocade’s former vice president of human resources, were originally charged with one count each of securities fraud in a criminal complaint on July 20 and indicted with additional charges Aug. 10.
