Item 4.     Ownership.

           This Schedule 13G restates and amends the previous Schedule 13G
filed with the Securities and Exchange Commission on May 12, 2005 by the
Reporting Persons which incorrectly aggregated the securities held by
Partners and Master Fund listed in Items 5-9 on pages three (3) and four
(4) of the previous Schedule 13G.

           Reference is hereby made to Items 5-9 and 11 of pages two (2),
three (3), four (4) and five (5) of this Schedule 13G, which Items are
incorporated by reference herein.

           Partners is the record owner of 276,506 shares of the Issuer's
common stock and Master Fund is the record owner of 220,196 shares of the
Issuer's common stock (collectively, the "Securities").  MMR as general
partner and investment manager of Partners and investment manager of Master
Fund and C. Fred Toney as managing member of MMR may be deemed to
beneficially own the Securities owned by Partners and Master Fund in that
they may be deemed to have the power to direct the voting or disposition of
the shares.

           Neither the filing of this Schedule 13G nor any of its contents
shall be deemed to constitute an admission that either MMR or Mr. Toney is,
for any purpose, the beneficial owner of any such Securities to which this
Schedule relates, and MMR and Mr. Toney disclaim beneficial ownership as to
the Securities, except to the extent of their respective pecuniary interests
therein.


MMR is an investment adviser.
C. Fred Toney is a control person.

           Under the definition of "beneficial ownership" in Rule 13d-3 under
the Securities Exchange Act of 1934, it is also possible that the individual
general partners, directors, executive officers, and members of the foregoing
entities might be deemed the "beneficial owners" of some or all of the
securities to which this Schedule relates in that they might be deemed to
share the power to direct the voting or disposition of such securities.
Neither the filing of this Schedule nor any of its contents shall be deemed
to constitute an admission that any of such individuals is, for any purpose,
the beneficial owner of any of the securities to which this Schedule relates,
and such beneficial ownership is expressly disclaimed.

Item 5.    Ownership of Five Percent or Less of a Class.

           If this statement is being filed to report the fact that as of the
date hereof the reporting person has ceased to be the beneficial owner of
more than five percent of the class of securities, check the following [X] as
to Partners and Master Fund.

Item 6.    Ownership of More Than Five Percent on Behalf of Another Person.

           Not applicable.

           the Security Being Reported on by the Parent Holding Company.
