INSTRUCTIONS FOR SCHEDULE 13G
INSTRUCTIONS FOR COVER PAGE
(1) Name 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 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), (11) Aggregate Amount Beneficially Owned by Each Reporting Person, 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.
(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 Advisor 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, reporting one 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 part of the schedule and accordingly being considered as "filed"
for the 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.
Page 3 of 7
<PAGE> 4
Disclosure of 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 in violation of the Federal securities laws and
rules promulgated thereunder.
