3.4 No Trading During Blackout Periods – No Company Personnel who are “Blacked Out Personnel” (as defined below) should trade in Company securities including the exercise of stock options during any “regularly scheduled blackout period” or “discretionary blackout period” (defined below) that the Disclosure Committee may designate and which will be communicated promptly on designation, generally by e-mail or other manner as appropriate in the circumstances. No Company Personnel should disclose to any persons that are not Company Personnel that a discretionary blackout period has been designated.
a. "regularly scheduled blackout periods" means periods in each case beginning the 10th day prior to the day on which the Company expects to release its annual or quarterly financial statements and ending 48 hours following such release of annual or quarterly financial statements.
b. "discretionary blackout periods" are imposed from time to time on Company Personnel by the Executive Chairman, or the CEO and at least one (1) other member of the Disclosure Committee (typically the Chairman of the CGNC), in addition to the regularly scheduled blackout periods, following consultation with the CEO, CFO, Chairman of the CGNC and Board as may be appropriate in the circumstances.
