        (a)     Name of Issuer

Item 2.

        (a)     Name of Person Filing

                This statement is being filed by (i) MicroCapital LLC, a
                Delaware limited liability company and registered investment
                adviser ("IA"), (ii) Ian P. Ellis ("Managing Member"), (iii)
                MicroCapital Fund LP, (iv) MicroCapital Fund Ltd., and (iv)
                Price Trust UTA Dated 10/5/84, As Amended (collectively, the
                "Reporting Persons"). Managing Member controls IA by virtue of
                Managing Member's position as managing member and majority owner
                of IA.

                IA's beneficial ownership of the Common Stock is direct as a
                result of IA's discretionary authority to buy, sell, and vote
                shares of such Common Stock for its investment advisory clients.
                Managing Member's beneficial ownership of Common Stock is
                indirect as a result of Managing Member's ownership and
                management of IA. The beneficial ownership of Managing Member is
                reported solely because Rules 13d-1(a) and (b) under the
                Securities Exchange Act of 1934, as amended, require any person
                who is "directly or indirectly" the beneficial owner of more
                than five percent of any equity security of a specified class to
                file a Schedule 13G. The answers in blocks 6, 8, 9 and 11 above
                and the response to item 4 by Managing Member are given on the
                basis of the "indirect" beneficial ownership referred to in such
                Rule, based on the direct beneficial ownership of Common Stock
                by IA and the relationship of Managing Member to IA referred to
                above.

                Information with respect to each Reporting Person is given
                solely by the respective Reporting Person, and no Reporting
                Person undertakes hereby any responsibility for the accuracy or
                completeness or such information concerning any other Reporting
                Person.

        (b)     Address of Principal Business office or, if None, Residence
