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.

#### VIII.
Post-Termination Transactions

If you are aware of material nonpublic information when you terminate service as a director, officer or employee of the Company, you may not trade in Company Securities until that information has become public or is no longer material. In all other respects, the procedures set forth in this Addendum will cease to apply to your transactions in Company Securities upon the expiration of any “blackout period” that is applicable to your transactions at the time of your termination of service.

#### IX.
General

Company Assistance . Any person who has a question about the Policy or this Addendum or their application to any proposed transaction may obtain additional guidance from the Chief Financial Officer or the Company’s legal counsel. In addition, if you have any doubt as to whether you are in possession of material nonpublic information or whether a trade may otherwise violate the Policy or this Addendum, you should contact the Company’s Chief Financial Officer or legal counsel before trading any securities of the Company.

Ultimately, however, the responsibility for adhering to the Policy and this Addendum and avoiding unlawful transactions rests with the individual director, officer and employee.

Other Procedures . The Company may change these procedures or adopt such other procedures in the future as the Company considers appropriate in order to carry out the purposes of the Policy and this Addendum or to comply with the federal securities laws. Wherever this Policy refers to, or calls for action by or involving the Company’s Chief Financial Officer, such reference shall include such other person as the Chief Financial Officer may designate from time to time, if the Chief Financial Officer is unavailable or otherwise unable to act for any reason.
