            itself--including each member of a group. Do not include the name of
            a person required to be identified in the report but who is not a
            reporting person. Reporting persons that are entities are also
            requested to furnish their I.R.S. identification numbers, although
            disclosure of such numbers is voluntary, not mandatory (see "SPECIAL
            INSTRUCTIONS FOR COMPLYING WITH SCHEDULE l3G" below).

      (2)   If any of the shares beneficially owned by a reporting person are
            held as a member of a group and that membership is expressly
            affirmed, please check row 2(a). If the reporting person disclaims
            membership in a group or describes a relationship with other persons
            but does not affirm the existence of a group, please check row 2(b)
            [unless it is a joint filing pursuant to Rule 13d1(k)(1) in
            which case it may not be necessary to check row 2(b).

      (3)   The third row is for SEC internal use; please leave blank.

      (4)   Citizenship or Place of Organization--Furnish citizenship if the
            named reporting person is a natural person. Otherwise, furnish place
            of organization.

     (11)   Etc.-- Rows(5) through (9) inclusive, and (11) are to be completed

            percentages are to be rounded off to the nearest tenth (one place
            after decimal point).

     (10)   Check if the aggregate amount reported as beneficially owned in row
            (9) does not include shares as to which beneficial ownership is
            disclaimed pursuant to Rule l3d-4 (17 CFR 240.13d-4] under the
            Securities Exchange Act of 1934.

Notes:      Attach as many copies of the second part of the cover page as are
            needed, one reporting person per page.

            Filing persons may, in order to avoid unnecessary duplication,
            answer items on the schedules (Schedule 13D, 13G or 14D) by
            appropriate cross references to an item or items on the cover
            page(s). This approach may only be used where the cover page item or
            items provide all the disclosure required by the schedule item.
            Moreover, such a use of a cover page item will result in the item
            becoming a part of the schedule and accordingly being considered as
            "filed" for purposes of Section 18 of the Securities Exchange Act or
            otherwise subject to the liabilities of that section of the Act.

            Reporting persons may comply with their cover page filing
            requirements by filing either completed copies of the blank forms
            available from the Commission, printed or typed facsimiles, or
            computer printed facsimiles, provided the documents filed have
            identical formats to the forms prescribed in the Commission's
            regulations and meet existing Securities Exchange Act rules as to
            such matters as clarity and size (Securities Exchange Act Rule
            12b-12).


              SPECIAL INSTRUCTIONS FOR COMPLYING WITH SCHEDULE 13G

Under Sections 13(d), 13(g), and 23 of the Securities Exchange Act of 1934 and
the rules and regulations thereunder, the Commission is authorized to solicit
the information required to be supplied by this schedule by certain security
holders of certain issuers.

Disclosure of the information specified in this schedule is mandatory, except
for I.R.S. identification numbers, disclosure of which is voluntary. The
information will be used for the primary purpose of determining and disclosing
the holdings of certain beneficial owners of certain equity securities. This
statement will be made a matter of public record. Therefore, any information
given will be available for inspection by any member of the public.

Because of the public nature of the information the Commission can use it for a
variety of purposes, including referral to other governmental authorities or
securities self-regulatory organizations for investigatory purposes or in
connection with litigation involving the Federal securities laws or other civil,
criminal or regulatory statutes or provisions. I.R.S. identification numbers, if
furnished, will assist the Commission in identifying security holders and,
therefore, in promptly processing statements of beneficial ownership of
securities.

Failure to disclose the information requested by this schedule, except for
I.R.S. identification numbers, may result in civil or criminal action against
the persons involved for violation of the Federal securities
