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),(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"

                                       3


               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.
