INSTRUCTIONS FOR COVER PAGE

(1)      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 the 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:

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 (Schedules 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 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.
