The Reporting Persons will continuously evaluate their ownership of Common Stock and the Issuer's business and industry. Depending on market conditions and other factors that the Reporting Persons may deem material to their investment decision, including the availability of other investment opportunities, each Reporting Person may from time to time acquire additional shares of Common Stock that such Reporting Person now owns or may hereafter acquire. Page 9 Without limitation of the foregoing (and consistent with their investment purpose), the Reporting Persons will continue to consider alternative courses of action and will in the future take such actions with respect to their investment in the Issuer as they deem appropriate in light of the circumstances existing from time to time. Such actions, in addition to that discussed above, may include making recommendations to members of management concerning various business strategies, acquisitions, policies, seeking to acquire control of the Issuer through a merger, proxy solicitation, tender offer, significant equity investment, exchange offer or otherwise, or such other actions as the Reporting Persons may deem appropriate. ________________________________________________________________________________ Item 5.
