#### I.
The Need For A Policy Statement

Under the federal securities laws, it is illegal to trade in transactions in the Company’s securities (collectively referred to in this Policy as “Company Securities”) while in the possession of material nonpublic information about the Company. It is also illegal to disclose or give material nonpublic information to others who may trade on the basis of that information or to advise others how to trade while in possession of material nonpublic information. Any person who possesses material nonpublic information about the Company is deemed to be an “insider.” The category of insiders isNOTlimited to officers and directors of the Company.

Insider trading violations are pursued vigorously by the Securities and Exchange Commission (the “SEC”) and the U.S. Department of Justice, and such violations are punished severely. While the regulatory authorities concentrate their efforts on the individuals who trade, or who tip inside information to others who trade, the federal securities laws also impose potential liability on companies and other controlling persons if they fail to take reasonable steps to prevent insider trading by company personnel. Both the SEC and the New York Stock Exchange are very effective at detecting and pursuing insider trading cases. The SEC has successfully prosecuted cases against employees trading through foreign accounts, trading by family members and friends, and trading involving only a small number of shares.

The Company has adopted this Statement of Company Policy Regarding Insider Trading (the “Policy”) both to satisfy the Company’s obligation to prevent insider trading and to help Company personnel avoid the severe consequences associated with violations of the insider trading laws. The Policy is also intended to prevent even the appearance of improper conduct on the part of anyone employed by or associated with the Company (not just the officers or directors of the Company). For clarity, this Policy also applies to family members, other members of a person’s household and entities controlled by a person covered by this Policy, as described below. The Company may also determine that other persons should be subject to this Policy, such as contractors or consultants who have access to material nonpublic information.

Each individual is responsible for making sure that he, she or they complies with this Policy, and that any family member, household member or entity whose transactions are subject to this Policy, as discussed below, also comply with this Policy.
