     Section 5.12 Private Offering by the Company. Neither the Company nor anyone acting on its behalf has offered the Series A Cumulative Convertible Preferred Stock or any similar securities for sale to, or solicited any offer to buy any of the same from, or otherwise approached or negotiated in respect thereof with, any person other than the Purchasers. Neither the Company nor anyone acting on its behalf has taken, or will take, any action that would subject the issuance or sale of the Series A Cumulative Convertible Preferred Stock to the registration requirements of Section 5 of the Securities Act or to the registration requirements of any securities or blue sky laws of any applicable jurisdiction.

     Section 5.13 Status under Certain Statutes. Neither the Company nor any Subsidiary is subject to regulation under the Investment Company Act of 1940, as amended (except in its capacity as an investment advisor to companies which are so regulated), the ICC Termination Act of 1995, as amended, or the Federal Power Act, as amended.
