Item 4. Ownership.

Reference is hereby made to Items 5-9 and 11 of page two (2) and

reference herein.

Of the 911,109 shares of the Company listed on page three (3) of
this Schedule, 875,709 shares are held by Wentworth (as reported on page
two (2) of this Schedule). Because Wentworth is a wholly owned subsidiary
of LNFG, it is possible that LNFG may be deemed a beneficial owner of the
shares held by Wentworth by virtue of the definition of "beneficial owner"
in Rule 13d-3 under the Securities Exchange Act of 1934. The filing of
this Schedule shall not be construed as an admission by LNFG that it is a
beneficial owner of any securities of the Company held by Wentworth.

The additional 35,400 shares of the Company listed on page
three (3) of this Schedule are held by Laird Norton Trust Company ("LNTC"),
another wholly owned subsidiary of LNFG. As with the shares held by
Wentworth, the filing of this Schedule shall not be construed as an
admission by LNFG that it is a beneficial owner of any of the securities of
the Company held by LNTC.

In addition, it is possible that the individual general partners,
directors, executive officers, members, and/or managers of Wentworth or
LNFG might be deemed the "beneficial owners" of some or all of the
securities to which this Schedule relates in that they might be deemed to
share the power to direct the voting or disposition of such securities.
Neither the filing of this Schedule nor any of its contents shall be deemed
to constitute an admission that any of such individuals is, for any purpose, the
beneficial owner of any of the securities to which this Schedule relates,
and such beneficial ownership is expressly disclaimed.

Item 5. Ownership of Five Percent or Less of a Class.

Not applicable.

Item 6. Ownership of More Than Five Percent on Behalf of
Another Person.

Wentworth is deemed to be the beneficial owner of the number of
securities reflected in Items 5-9 and 11 of page two (2) of this Schedule
13G pursuant to separate arrangements whereby Wentworth acts as investment
adviser to certain persons. Each person for whom the reporting person acts
as investment adviser has the right to receive or the power to direct the
receipt of dividends from, or the proceeds from the sale of, the Common
Stock purchased or held pursuant to such arrangements.

Wentworth is an investment adviser in accordance with Rule 13d-1(b)(1)
(ii)(E). LNTC is a bank in accordance with Rule 13d-1(b)(1)(ii)(B).

Item 8. Identification and Classification of Members of the
Group.

Not applicable.

Item 9. Notice of Dissolution of Group.

Not applicable.

Item 10. Certification.
