common stock pursuant to a certain Stock Purchase Agreement dated as of May 4,
2006. MSR I SBIC, L.P. is an entity ultimately controlled by Levinson.
Accordingly, Levinson may be deemed to beneficially own 786,937 shares of common
stock held by MSR I SBIC, L.P. (including the 240,000 shares issued to MSR SBIC
I, L.P. on May 8, 2006) as well as (i) 3,000 shares of common stock held by
Tri-Lev LLC, (ii) 50,000 shares of common stock underlying warrants held by MSR
Advisors, Inc. and (iii) 5,000 shares of common stock underlying a stock option
held by Levinson. The source of funds for the purchase of the 240,000 shares of
common stock was working capital of MSR I SBIC, L.P.

ITEM 4.  PURPOSE OF TRANSACTION

      The Common Stock has been acquired for the purpose of making an investment
in the Issuer and not with the present intention of acquiring control of the
Issuer's business. Levinson participates directly in the management of the
Issuer through representation on the Issuer's Board of Directors (the "Board")
by virtue of Levinson's appointment to fill a vacancy on the Board effective as
of May 1, 2003.

      The Reporting Persons intend to review the investment in the Issuer on the
basis of various factors, including the Issuer's business, financial condition,
results of operations and prospects, general economic and industry conditions,
the securities markets in general and those for the Issuer's securities in
particular, as well as other developments and other investment opportunities.
Based upon such review, the Reporting Persons will take such actions in the
future as they may deem appropriate in light of the circumstances existing from
time to time. If the Reporting Persons believe that further investment in the
Issuer is attractive, whether because of the market price of the Issuer's
securities or otherwise, they may acquire shares of Common Stock or other
securities of the Issuer either in the open market or in privately-negotiated
transactions. Similarly, depending on market conditions and other factors, the
Reporting Persons may determine to dispose of some or all of the securities
currently owned by the Reporting Persons or otherwise acquired by the Reporting
Persons either in the open market or in privately negotiated transactions.

      Except as set forth above, the Reporting Persons have not formulated any
plans or proposals that relate to or would result in:

      (a)   The acquisition by any person of additional securities of the
            Issuer, or the disposition of securities of the Issuer;

--------------------------------------------------------------------------------

      (b)   An extraordinary corporate transaction, such as a merger,
            reorganization or liquidation involving the Issuer or any of its
            subsidiaries;

      (c)   A sale or transfer of a material amount of assets of the Issuer or
            any of its subsidiaries;

      (d)   Any change in the present Board of Directors or management of the
            Issuer, including any plans or proposals to change the number of or
            term of directors or to fill any existing vacancies on the Board;

      (e)   Any material change in the present capitalization or dividend policy
            of the Issuer;

      (f)   Any other material change in the Issuer's business or corporate
            structure;

      (g)   Changes in the Issuer's charter, by-laws, or instruments
            corresponding thereto or other actions that may impede the
            acquisition of control of the Issuer by any person;

      (h)   Causing a class of the securities of the Issuer to be delisted from
            a national securities exchange or cease to be authorized to be
            quoted in an inter-dealer quotation system of a registered national
            securities association;

      (i)   A class of equity securities of the Issuer becoming eligible for
            termination of registration pursuant to Section 12(g)(4) of the
            Securities Exchange Act of 1934, as amended; or

      (j)   Any action similar to any of those listed above.

ITEM 5.  INTEREST IN SECURITIES OF THE ISSUER

      (a) and (b) As a result of certain relationships, each of the Reporting
Persons may be deemed to directly and/or indirectly beneficially own up to
844,937 shares of Common Stock, representing in the aggregate approximately
18.3% of the outstanding shares of Common Stock, based on (i) the number of
shares of Common Stock reported to be outstanding as of December 12, 2005, in
the Issuer's Quarterly Report on Form 10-QSB for the period ended October 31,
2005, as filed with the Securities and Exchange Commission (the "SEC") on
December 14, 2005, together with (ii) an aggregate of 760,000 shares of Common
Stock issued by the Issuer on or about May 8, 2006 (including 240,000 shares of
Common Stock which are the subject of this Schedule 13D), (iii) 50,000 shares
underlying warrants and (iv) 5,000 shares underlying a stock option. The table
below sets forth the number of shares of Common Stock that may be deemed to be
directly and indirectly beneficially owned by each Reporting Person. Each
Reporting Person expressly disclaims beneficial ownership of any securities
beneficially owned by any other Reporting Person.

      Due to their relationship with one another, the Reporting Persons may be
deemed to constitute a "group" under Section 13(d) of the Securities Exchange
Act of 1934, as amended (the "Act"), with respect to their beneficial ownership
of the shares of Common Stock, warrants and stock option. The Reporting Persons,
however, expressly disclaim such status and declare that the filing of this
Schedule 13D is not and should not be deemed an admission that any Reporting
Person, for purposes of Section 13(d) of the Act or otherwise, is the beneficial
owner of the shares of Common Stock or warrants held by any other Reporting
Person.
