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 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.

          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"

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 13G                                                         Page 4 of 7

          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.
