Item 4.   Ownership.

          Reference is hereby made to Items 5-9 and 11 of page two (2) and
page three (3) of this Schedule 13G, which Items are incorporated by
reference herein.

          Of the 1,204,025 shares of the Company listed on page three (3)
of this Schedule, 1,052,025 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 152,000 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.

          Which Acquired the Security Being Reported on by the
          Parent Holding Company.

LNTC.  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 9.   Notice of Dissolution of Group.

          Not applicable.
