INSTRUCTIONS FOR SCHEDULE 13G

Instructions for Cover Page

(l) Names and I.R.S. Identification Numbers of Reporting
Persons--Furnish the full legal name of each person for whom
the report is filed--i.e., each person required to sign the
schedule 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 13G" 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.

(5)-(9), Aggregate Amount Beneficially Owned By Each Reporting Person,
(11) Etc.--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 (17 CFR
240.13d-4} under the Securities Exchange Act of 1934.
3

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

Category Symbol

Broker Dealer BD
Bank BK
Insurance Company IC
Investment Company IV
Investment Adviser IA
Employee Benefit Plan, Pension Fund, or Endowment Fund EP
Parent Holding Company/Control Person HC
Savings Association SA
Church Plan CP
Corporation CO
Partnership PN
Individual IN
Other OO



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 14D1) 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 laws and rules
promulgated thereunder.
