Corporation (the "Company") solely to report the information set forth in Item 1
hereof.

Item 1.           Registrant's Business and Operations

         Item 1.01         Entry into a Material Definitive Agreement

                  a.       Salary Continuation Plan Amendments

         For some  years,  the  Company  has had a Salary  Continuation  Plan in
effect, as described most recently in the Company's proxy statement for its 2004
Annual  Meeting of  Shareholders.  The plan is  designed  to attract  and retain
senior  management  and provide for  continuity of management in the event of an
actual or threatened  change in control of the Company.  It covered  officers of
the  Company at the level of vice  president  or above,  under the age of 65 and
having at least  one year of  Company  service  (presently  including  Walter C.
Johnsen,  Brian S.  Olschan,  Paul G.  Driscoll,  James A. Benkovic and Larry H.
Buchtmann).

         The  plan  provided  that,  in the  event of a change  in  control  (as
described in the plan),  each covered  officer  would have  specific  rights and
receive  certain  benefits if,  within one year after such change in control (or
two years in the case of  officers  who are also  directors),  the  officer  was
actually or constructively  discharged either by: (i) involuntary termination of
the  officer's  employment  by the  Company;  (ii)  reduction  in the  officer's
responsibility,  status or  compensation;  or (iii) transfer of the officer to a
location  unreasonably  distant  from  his  or her  current  location.  In  such
circumstances,  the compensation  which the officer would be entitled to receive
would be a lump sum  payment  equal to: (x) nine  months  compensation  for vice
presidents; (y) eighteen months compensation for senior vice presidents; and (z)
thirty months for officers at the senior vice president level and above who were
also directors  ("director/officers").  Compensation was based upon the level of
the officer's  non-deferred  compensation  in effect  immediately  preceding the
change in control. In addition,  any vice president,  senior vice president,  or
director/officer  resigning  within six months (one year for  director/officers)
after specified  changes in control (as described in the plan) would be entitled
to six months, twelve months, or twenty-four months compensation, respectively.

         On  September  28, 2004,  the Company  adopted  certain  changes to the
Salary Continuation Plan, including the following:

         1. The  requirement  that a covered  officer be employed by the Company
for one year prior to qualifying for benefits under the plan was eliminated.

         2. The  number  of months  compensation  payable  to a vice  president,
senior  vice  president  or  director/officer  under the plan in the event of an
actual or  constructive  discharge  was  increased  from nine  months,  eighteen
months,  or thirty  months,  respectively,  to twenty-four  months,  twenty-four
months  or  thirty-six  months,  respectively.  (The  distinction  between  vice
presidents and senior vice presidents was eliminated).





         3. The number of months compensation payable to an officer in the event
of the  officer's  resignation  was increased to be the same number of months as
would be payable in the event of an involuntary termination.

         4. Life and medical  insurance  coverage was added to the plan and will
continue over the number of months that compensation is payable.

         5. Incentive bonus payments have been added to the compensation payable
based on prior incentive bonus payments.

         b.     Severance Pay Plan Amendments

         For some years, the Company has had a Severance Pay Plan in effect,  as
described  most  recently in the Company's  proxy  statement for its 2004 Annual
Meeting of  Shareholders.  The plan is designed to enable the Company to attract
and retain key  employees.  It covered  officers  of the Company at the level of
vice  president  or above,  under the age of 65 and  having at least one year of
Company service (presently including Walter C. Johnsen,  Brian S. Olschan,  Paul
G. Driscoll, James A. Benkovic and Larry H. Buchtmann).

         The plan provided that, in the event the key employee's  employment was
terminated  by the  Company  involuntarily  (for any  reason  other  than  gross
misconduct);  his or her responsibility,  status or compensation was reduced; or
he or she was  transferred  to a location  unreasonably  distant from his or her
current  location,  he or she shall be entitled to benefits  under the plan.  In
such  circumstances,  the  compensation  which the employee would be entitled to
receive  would be a lump sum payment  equal to one month  compensation  for each
year of service to the Company,  with vice presidents receiving a minimum of two
months  and a  maximum  of nine  months  compensation,  senior  vice  presidents
receiving  a  minimum  of  four   months  and  a  maximum  of  eighteen   months
compensation,  and presidents and executive vice presidents  receiving a minimum
of six months and a maximum of twenty months compensation. This plan would apply
only if the Salary  Continuation Plan (described above) does not apply, and only
if the employee was not eligible for his or her full pension from the Company at
the time of termination.

         The plan also provided that, in the event a vice president, senior vice
president  or  president/executive  vice  president  died in office,  his or her
beneficiaries  would be entitled to a lump sum payment equal to two months, four
months, or six months compensation, respectively.
On September 28, 2004, the Company  adopted certain changes to the Severance Pay
Plan, including the following:

         1. The requirement  that an employee be employed by the Company for one
year prior to qualifying for benefits under the plan was eliminated.

         2. The  distinction  between vice presidents and senior vice presidents
was eliminated for purposes of  calculating  benefits under the plan,  with vice
presidents being entitled to receive the same benefits as senior vice presidents
(as described in paragraphs 3, 4 and 5 below).





         3. The minimum  compensation  payable to a vice president,  senior vice
president or  president/executive  vice president upon termination was increased
from two months,  four months, or six months,  respectively,  to six months, six
months, or nine months, respectively.

         4. The maximum  compensation  payable to a vice president,  senior vice
president or  president/executive  vice president upon termination was increased
from nine months, eighteen months, or twenty months,  respectively,  to eighteen
months, eighteen months, or thirty months, respectively.

         5. The compensation  payable to the  beneficiaries of a vice president,
senior vice  president or  president/executive  vice president upon the death of
such  officer  was  increased  from two  months,  four  months,  or six  months,
respectively, to six months, six months, or nine months, respectively.

         Pursuant to the  requirements  of the Securities  Exchange Act of 1934,
