The
Reporting Persons intend to review and evaluate their investment in the
Common Stock on an ongoing basis and may, depending upon their evaluation
of the business and prospects of the Company, or such other considerations
as they may deem relevant, determine to increase, decrease, or dispose of
their holdings of Common Stock. As a part of such review and
evaluation, the Reporting Persons may hold discussions with the Company’s
management and directors, other shareholders and other interested
parties.
Except
as otherwise described in this Item 4, the Reporting Persons do not have
present plans or proposals that relate to or would result in any of the
following (although the Reporting Persons reserve the right to develop
such plans or proposals or any other plans relating to the Company and to
take action with respect thereto): (i) the acquisition by any
person of additional securities of the Company, or the disposition of
securities of the Company; (ii) an extraordinary corporate
transaction, such as a merger, reorganization, or liquidation, involving
the Company or any of its subsidiaries; (iii) a sale or transfer of a
material amount of assets of the Company or any of its subsidiaries;
(iv) any change in the present board of directors or management of
the Company, including any plans or proposals to change the number or term
of directors or to fill any existing vacancies on the board; (v) any
material change in the present capitalization or dividend policy of the
Company; (vi) any other material change in the Company’s business or
corporate structure; (vii) changes in the Company’s certificate of
incorporation, bylaws, or instruments corresponding thereto or other
actions that may impede the acquisition of control of the Company by any
person; (viii) causing a class of securities of the Company 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; (ix) a class of equity securities of the
Company becoming eligible for termination of registration pursuant to
Section 12(g)(4) of the Securities Exchange Act of 1934, as
amended; or (x) any action similar to any of those enumerated
above.
