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).


Under Sections 13(d), 13(9), 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 Social Security or l.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
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 statutes or provisions, Social Security or l.R.S.
identification numbers, if furnished, will assist the Commission in identifying
security holders and, therefore, in prompt processing statements of beneficial
ownership of securities. Failure to disclose the information requested by this
schedule, except for Social Security or l.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.
