Instructions

(1)

Names 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.

(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 another person but does not affirm the existence of the group, please check row 2(b) [unless it is 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) Aggregated 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).

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 TO) 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 12-b12).
