 event-specific blackout should not disclose the existence of the blackout to any other person.

Rule 10b5-1 Plans Exception. The requirement for pre-clearance, the quarterly trading restrictions and event-specific trading restrictions do not apply to transactions conducted pursuant to approved Rule 10b5-1 plans, described under the heading “Rule 10b5-1 Plans” in the Policy.

Hardship Exception. A person who is subject to a quarterly earnings blackout period and who has an unexpected and urgent need to sell Company’s securities in order to generate cash may, in appropriate and very limited and rare circumstances, be permitted to sell such securities even during the blackout period. A hardship exception may be granted only by the Audit Committee of the Board of Directors of the Company, at its sole discretion, and such exception must be requested at least five business days in advance of the proposed trade. A hardship exception may be granted only if the Audit Committee concludes that the Company’s earnings information for the applicable quarter does not constitute material nonpublic information or if the Company does not have sufficient insight as to the Company’s earnings information as of that time. It is highly unlikely that a hardship exception will be granted.
