    Re:   Request for Stockholder Information

Dear Mr. Kruse:

          I represent PL Capital, LLC in connection with its request for a
stockholder list and certain other information which was sent to your attention
on December 18, 2000. A copy of my client's request is enclosed for your
convenience. In your January 4, 2001 response to this request, you indicated
that Wells Financial Corp. ("Wells") does not have in its possession a current
list or "breakdown" of the various brokerage firms holding Wells stock in the
names of central depository systems such as CEDE & Co.

          On behalf of PL Capital, LLC I am requesting that you obtain a current
list of brokerage firms holding Wells stock in the name of any central
depository system and that you provide this information to my client. The Courts
which have addressed this issue have universally held that a public corporation,
such as Wells, cannot provide a meaningful response to a request for a
stockholder list without this information. Because the brokerage firms own the
stock for the benefit of their customers, but hold title in the name of the
central depository, a stockholder cannot ascertain the identity of his fellow
stockholders without this information, which can be obtained by Wells quickly
and easily upon request.

          Your cooperation in this matter is greatly appreciated. Please call me
at your earliest convenience with any questions or concerns.

                                        Very truly yours,

                                        /s/ Phillip M. Goldberg

                                        Phillip M. Goldberg

Enclosure(s)
