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 person but does not
affirm the existence of a group, please check row 2(b)[unless it is a
joint filing pursuant to Rule 13d-1(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.

(5)-(9), Aggregated Amount Beneficially Owned By Each Reporting Person, etc.--
(11)	Rows (5) through (9) inclusive, and (11) are to be completed in
accordance with the provisions of Item 4 of Schedule 13G. All
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 13d-4 under the Securities Exchange Act of 1934.

(12)	Type of Reporting Person--Please classify each "reporting person"
according to the following breakdown (see Item 3 of Schedule 13G) and

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-1) 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 utilize 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 statues 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 laws and rules
promulgated thereunder.
