Item 2. 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.
