Identity and Background (a) The name, residence or business address, and the principal occupation or employment and the name, principal business and address of any corporation or other organization in which such employment is conducted, of each executive officer and director and each controlling person, if any, of the reporting persons named above is set forth in Exhibit A hereto. To the best knowledge of the persons listed in Item 2 hereof, each person listed on Exhibit A is a United States citizen except where otherwise noted and, during the last five years, no person listed in Exhibit A attached (i) has been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors) or (ii) has been a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to, a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities such laws. Item 3. Source and Amount of Funds or Other Consideration The securities reported herein were acquired with funds of approximately $31 million (including brokerage commissions). FAI's advisory clients provided all such funds. Item 4. Purpose of Transaction The securities covered by this Statement were acquired by FAI's advisory clients for the purpose of investment. Neither FAI, nor any executive officer or director of FAI, has any present plans or intentions to acquire or dispose of any securities of the Issuer other than on behalf of FAI's clients for the purpose of investment. The Issuer's proxy statement solicits shareholder approval of a proposed preferred stock financing and certain other matters. Franklin Advisers, Inc ("FAI") believes that this proposed financing is excessively dilutive of the Issuer's equity shareholders and that certain members of management and the Board of Directors of the Issuer have interests in connection with the proposed financing that maybe in conflict with the interests of the Issuer's equity shareholders. Accordingly FAI intends to vote AGAINST all proposals in the proxy and may discuss its views with other shareholders of the Issuer. In the future, FAI may decide to purchase on behalf of its advisory clients' additional shares of the Common Stock or other securities of the Issuer. In addition, FAI may cause its advisory clients to dispose of any or all securities of the Issuer in any manner permitted by applicable securities laws. FAI's advisory clients reserve the right to exercise any and all of their respective rights as a stockholder of the Issuer in a manner consistent with their equity interests. Other than as described above, neither FAI nor any executive officer or director of FAI, has any present plans or proposals, which relate to or would result in: i) an extraordinary corporate transaction, such as a merger, reorganization or liquidation, involving the Issuer or any of its subsidiaries; (ii) the sale or transfer of a material amount of assets of the Issuer or any of its subsidiaries; (iii) any change in the present board of directors or management of the Issuer, including any plans or proposals to change the number or term of directors or to fill any existing vacancies on the board; (iv) any material change in the present capitalization or dividend policy of the Issuer; (v) any other material change in the Issuer's business or corporate structure; (vi) changes in the Issuer's charter, bylaws or instruments corresponding thereto or other actions, which may impede the acquisition of control of the Issuer by any person; (vii) causing a class of securities of the Issuer to be delisted from a national securities exchange or to cease to be authorized to be quoted in an inter-dealer quotation system of a registered national securities association; (viii) a class of equity security of the Issuer becoming eligible for termination of registration pursuant to Section 12(g)(4) of the Securities Exchange Act of 1934; or (ix) any action similar to any of those enumerated above. Item 5. Interest in Securities of the Issuer (a-b) FAI's advisory clients are the owners of 3,907,612 shares of the Common Stock representing approximately 9.95% of the outstanding shares of Common Stock. Since FAI's advisory contracts with its clients grant to FAI sole investment power over the securities owned by its advisory clients, FAI may be deemed to be, for purposes of Rule 13d-3 under the 1934 Act (the "1934 Act"), the beneficial owner of the securities covered by this statement. FAI is a wholly owned subsidiary of Franklin Resources, Inc. ("FRI"). Charles B. Johnson and Rupert H. Johnson, Jr. (the "Principal Shareholders") each own in excess of 10% of the outstanding Common Stock of FRI and are the principal shareholders of FRI. FRI and the Principal Shareholders therefore may be deemed to be, for purposes of Rule 13d-3 under the 1934 Act, the beneficial owner of securities held by persons and entities advised by FRI or its subsidiaries. FAI, FRI and the Principal Shareholders each disclaim any economic interest or beneficial ownership in any of the securities covered by this Statement owned by advisory clients of FRI subsidiaries. Furthermore, FRI, FAI, and the Principal Shareholders are of the view that they are not acting as a "group" for purposes of Section 13(d) under the 1934 Act and that they are not otherwise required to attribute to each other the "beneficial ownership" of securities held by any of them or by any persons or entities advised by FRI subsidiaries. (c) There were the following transactions in the shares of the Common Stock within the past sixty days (see Exhibit B). (d) No person other than respective advisory clients of FAI have the right to receive or the power to direct the receipt of dividends from, or the proceeds of the sale of the securities being reported herein. (e) Not applicable. Item 6. Contracts, Arrangements, Understandings, or Relationships with Respect to Securities of the Issuer Other than as disclosed above, no persons named in Item 2 herein, nor to the best of such person's knowledge, no person named in Exhibit A hereto, has any contract, arrangement, understanding or relationship (legal or otherwise) with any person with respect to any securities of the Issuer, including, but not limited to, transfer or voting of any securities, finders' fees, joint ventures, loan or option arrangements, puts or calls, guarantees of profits, division of profits or losses, or the giving or withholding of proxies. Item 7. Materials to be Filed as Exhibits Exhibit A Executive Officers and Directors of Reporting Persons Exhibit B Summary of transactions within the last sixty days After reasonable inquiry, and to the best of my knowledge and belief, I certify that the information set forth in this statement is true, complete, and correct.
