Item 4  Ownership

 The securities reported herein are beneficially owned by one or more
 registered investment companies or other managed accounts that are
 investment management clients of Royce & Associates, LP ("RALP"), an
 indirect majority owned subsidiary of Franklin Resources, Inc.("FRI").
 When an investment management contract (including a sub advisory
 agreement) delegates to RALP investment discretion or voting power over
 the securities held in the investment advisory accounts that are
 subject to that agreement, FRI treats RALP as having sole investment
 discretion or voting authority, as the case may be, unless the
 agreement specifies otherwise. Accordingly, RALP reports on Schedule
 13G that it has sole investment discretion and voting authority over
 the securities covered by any such investment management agreement,
 unless otherwise noted in this Item 4. As a result, for purposes of
 Rule 13d 3 under the Act, RALP may be deemed to be the beneficial owner
 of the securities reported in this Schedule 13G.

 Beneficial ownership by investment management subsidiaries and other
 affiliates of FRI is being reported in conformity with the guidelines
 articulated by the SEC staff in Release No. 34 39538 (January 12, 1998)
 relating to organizations, such as FRI, where related entities exercise
 voting and investment powers over the securities being reported
 independently from each other. The voting and investment powers held by
 RALP are exercised independently from FRI (RALP's parent holding
 company) and from all other investment management subsidiaries of FRI
 (FRI, its affiliates and investment management subsidiaries other than
 RALP are, collectively, "FRI affiliates"). Furthermore, internal
 policies and procedures of RALP and FRI affiliates establish
 informational barriers that prevent the flow between RALP and the FRI
 affiliates of information that relates to the voting and investment
 powers over the securities owned by their respective investment
 management clients. Consequently, RALP and the FRI affiliates report
 the securities over which they hold investment and voting power
 separately from each other for purposes of Section 13 of the Act.

 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 stockholders of FRI. However,
 because RALP exercises voting and investment powers on behalf of its
 investment management clients independently of FRI affiliates,
 beneficial ownership of the securities reported by RALP is not
 attributed to the Principal Shareholders. RALP disclaims any pecuniary
 interest in any of the securities reported in this Schedule 13G.  In
 addition, the filing of this Schedule 13G on behalf of RALP should not
 be construed as an admission that it is, and it disclaims that it is,
 the beneficial owner, as defined in Rule 13d 3, of any of such
 securities.

 Furthermore, RALP believes that it is not a "group" with FRI
 affiliates, the Principal Shareholders, or their respective affiliates
 within the meaning of Rule 13d 5 under the Act and that none of them is
 otherwise required to attribute to any other the beneficial ownership
 of the securities held by such person or by any persons or entities for
 whom or for which RALP or the FRI affiliates provide investment
 management services.
