        Funds for the purchase of the Shares reported herein were derived from

ITEM 4.           PURPOSE OF TRANSACTION.

          The Reporting Persons originally acquired Shares for investment in the
ordinary course of business because they believed that the Shares, when
purchased, were undervalued and represented an attractive investment
opportunity. On December 19, 2006, CGI delivered a letter to the Issuer stating
its belief that the market price of the Shares fails to reflect the stand-alone
value of the Issuer's operating subsidiaries. The letter also indicated CGI's
desire to work constructively with the Issuer's management to continue to
evaluate multiple strategic alternatives for the Issuer, including, but not
limited to, a tax-free spin-off or sale to strategic acquirors of one or more of
the Issuer's subsidiaries, or a going-private transaction for the Issuer. A copy
of this letter is attached hereto as Exhibit B and is incorporated herein by
reference.

         Except as set forth herein or as would occur upon completion of any of
the actions discussed herein, including in any Exhibits hereto, the Reporting
Persons have no present plan or proposal that would relate to or result in any
of the matters set forth in subparagraphs (a)-(j) of Item 4 of Schedule 13D. The
Reporting Persons intend to review their investment in the Issuer on a
continuing basis and may engage in discussions with management, the board of
directors, other shareholders of the Issuer and other relevant parties
concerning the business, operations, management, strategy and future plans of
the Issuer. Depending on various factors including, without limitation, the
Issuer's financial position and strategic direction, the outcome of the
discussions and actions referenced above, actions taken by the board of
directors, price levels of the Shares, other investment opportunities available
to the Reporting Persons, conditions in the securities market and general
economic and industry conditions, the Reporting Persons may in the future take
such actions with respect to their investment in the Issuer as they deem
appropriate including, without limitation, purchasing additional Shares or
selling some or all of their Shares, engaging in short selling of or any hedging
or similar transactions with respect to the Shares and/or otherwise changing
their intention with respect to any and all matters referred to in Item 4 of
Schedule 13D.

ITEM 5.           INTEREST IN SECURITIES OF THE ISSUER.

          (a) As of the close of business on December 19, 2006, the Reporting
Persons beneficially owned an aggregate of 1,538,944 Shares, constituting
approximately 5.2% of the Shares outstanding.

          The aggregate percentage of Shares beneficially owned by the Reporting
Persons is based upon 29,824,789 Shares outstanding, which is the total number
of Shares outstanding as of December 8, 2006 as reported in the Issuer's Annual
Report on Form 10-K for the period ended September 30, 2006.

          (b) By virtue of investment management agreements with each of CMSF
and CSO, CGI has the power to vote or direct the voting, and to dispose or
direct the disposition, of all of the 1,433,244 Shares held by CMSF and the
105,700 Shares held by CSO. By virtue of his direct and indirect control of CGI,
George Hall is deemed to have shared voting power and shared dispositive power
with respect to all Shares as to which CGI has voting power or dispositive
power. By virtue of his position as managing director and senior portfolio
manager of CGI, Conrad Bringsjord is also deemed to have shared voting power and
shared dispositive power with respect to all Shares as to which CGI has voting
power or dispositive power. Accordingly, CGI, George Hall and Conrad Bringsjord
are deemed to have shared voting and shared dispositive power with respect to an
aggregate of 1,538,944 Shares.

          (c) Information concerning transactions in the Shares effected by the
Reporting Persons during the past sixty days is set forth in Schedule B hereto
and is incorporated herein by reference. Unless otherwise indicated, all of such
transactions were effected in the open market.

          (d) No person other than the Reporting Persons is known to have the
right to receive or the power to direct the receipt of dividends from, or the
proceeds from the sale of, the Shares.

          (e) Not applicable.

Item 6.           CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH
                  RESPECT TO SECURITIES OF THE ISSUER.

          The Reporting Persons may, from time to time, enter into and dispose
of cash-settled equity swap or other similar derivative transactions with one or
more counterparties that are based upon the value of Shares, which transactions
may be significant in amount. The profit, loss and/or return on such contracts
may be wholly or partially dependent on the market value of the Shares, the
relative value of Shares in comparison to one or more other financial
instruments, indexes or securities, a basket or group of securities in which
Shares may be included, or a combination of any of the foregoing. In addition to
the Shares that they beneficially own without reference to these contracts, the
Reporting Persons currently have long economic exposure to 559,200 Shares
through such contracts. These contracts do not give the Reporting Persons direct
or indirect voting, investment or dispositive control over any securities of the
Issuer and do not require the counterparties thereto to acquire, hold, vote or
dispose of any securities of the Issuer. Accordingly, the Reporting Persons
disclaim any beneficial ownership in any securities that may be referenced in
such contracts or that may be held from time to time by any counterparties to
such contracts.

          Except as otherwise set forth herein, the Reporting Persons do not
have any contract, arrangement, understanding or relationship with any person
with respect to the securities of the Issuer.
