                         INSTRUCTIONS FOR SCHEDULE 13G

INSTRUCTIONS FOR COVER PAGE

 (1) Names and Social Security 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 are also requested to
     furnish their Social Security or 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 such membership is expressly affirmed, please check
     row 2(a).  If the membership in a group is disclaimed or the reporting
     person describes a relationship with other persons but does not affirm the
     existence of a group, please check row 2(b) [unless a joint filing pursuant
     to Rule 13d-1(e)(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 Company IV Investment Adviser IA Employee Benefit Plan, Pension Fund, or Endowment Fund EP Patent Holding Company HC Corporation CO Partnership PN Individual IN Other OO
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 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 Page 6 of 12 pages holders of certain issuers. Disclosure of the information specified in this schedule is mandatory, except for Social Security or 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 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 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 Social Security or 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. GENERAL INSTRUCTIONS A. Statements containing the information required by this schedule shall be filed not later than February 14 following the calendar year covered by the statement or within the time specified in Rule 13d-1(b)(2), if applicable. B. Information contained in a form which is required to be filed by rules under section 13(f) (15 U.S.C. 78m(f)) for the same calendar as that covered by a statement on this schedule may be incorporated by reference in response to any of the items of this schedule. If such information is incorporated by reference in this schedule, copies of the relevant pages of such form shall be filed as an exhibit to this schedule. C. The item numbers and captions of the items shall be included but the text of the items is to be omitted. The answers to the items shall be so prepared as to indicate clearly the coverage of the items without referring to the text of the items. Answer every item. If an item is inapplicable or the answer is in the negative, so state. ITEM 1. (a)Name of Issuer (b)Address of Issuer's Principal Executive Offices ITEM 2. (a)Name of Person Filing (b)Address of Principal Business Office or, if none, Residence (c)Citizenship (d)Title of Class of Securities (e)CUSIP Number ITEM 3.
