       (ix)   (A) A person or entity  "beneficially  owns" voting  shares of the

Corporation  if such  person or entity,  directly  or  indirectly,  through  any

contract, arrangement,  understanding,  relationship, or otherwise has or shares

(1) voting power which  includes the power to vote,  or to direct the voting of,

such voting shares, or (2) investment power which includes the power to dispose,

or to direct the disposition of, such voting shares. Any person or entity which,

directly  or  indirectly,  creates or uses a trust,  proxy,  power of  attorney,

pooling  arrangement  or any other  contract,  arrangement,  or device


with the  purpose or effect of  divesting  such  person or entity of  beneficial

ownership of voting shares of the  Corporation or preventing the vesting of such

beneficial  ownership  as part of a plan or scheme to avoid  becoming  a Related

Person shall be deemed for purposes of this Article V to be the beneficial owner

of such voting shares.  All voting shares of the Corporation  beneficially owned

by a person or entity,  regardless of the form which such  beneficial  ownership

takes,  shall be  aggregated in  calculating  the number of voting shares of the

Corporation  beneficially  owned by such person or entity.  Any voting shares of

the Corporation  that any person or entity has the right to acquire  pursuant to

any agreement, contract,  arrangement, or understanding, or upon exercise of any

conversion right,  warrant, or option, or pursuant to the automatic  termination

of a trust, discretionary account or similar arrangement,  or otherwise shall be

deemed  beneficially  owned by such person or entity.  Any voting  shares of the

Corporation  not  outstanding  which any person or entity has a right to acquire

shall be deemed to be outstanding for the purpose of computing the percentage of

outstanding  voting shares of the Corporation  beneficially owned by such person

or entity but shall not be deemed to be outstanding for the purpose of computing

the  percentage of  outstanding  voting shares of the  Corporation  beneficially

owned by any other person or entity.


              (B) Notwithstanding  the  foregoing   provisions  of  subparagraph

(b)(ix)(A) hereof:


              (1) A member of a national securities exchange shall not be deemed

to be a beneficial  owner of voting shares of the  Corporation  held directly or

indirectly  by it on behalf of  another  person or entity  solely  because  such

member is the record holder of such voting shares and,  pursuant to the rules of

such exchange,  may direct the vote of such voting shares,  without instruction,

on other than  contested  matters or matters that may affect  substantially  the

rights or privileges of the holders of the voting shares of the  Corporation  to

be voted,  but is otherwise  precluded by the rules of such exchange from voting

without instruction;


              (2) A commercial bank, broker or dealer or insurance company which

in the  ordinary  course  of  business  is a  pledgee  of  voting  shares of the

Corporation  under a  written  pledge  agreement  shall  not be deemed to be the

beneficial  owner of such pledged  voting shares until the pledgee has taken all

formal  steps  necessary to declare a default and  determines  that the power to

vote or to direct the vote or to dispose  or to direct the  disposition  of such

pledged  securities  will be exercised,  provided that the pledgee  agreement is

bona fide and was not  entered  into  with the  purpose  nor with the  effect of

changing or influencing  the control of the  Corporation  nor in connection with

any  transaction  having such purpose or effect and, prior to default,  does not

grant to the  pledgee  the  power to vote or to direct  the vote of the  pledged

voting shares of the Corporation; and


              (3) A person or entity  engaged in business as an  underwriter  of

securities  who  acquires   voting  shares  of  the   Corporation   through  its

participation in good faith in a firm commitment  underwriting  registered under

the  Securities  Act of 1933, or comparable  successor  law, rule or regulation,

shall not be deemed to be the  beneficial  owner of such voting shares until the

expiration of forty days after the date of such acquisition.


              (x) A merger shall mean a statutory merger or consolidation.


              (c) For the purposes of this Article V the Continuing Directors by

a vote  of not  less  than  the  greater  of (A)  two-thirds  or (B)  two of the

Continuing Directors shall have the power to make a good faith determination, on

the basis of  information  known to them, of: (i) the number of voting shares of

the Corporation that any person or entity  "beneficially  owns",  (ii) whether a

person or entity is an  Affiliate or  Associate  of another,  (iii)  whether the

assets  subject  to  any  Related  Person  Business  Transaction   constitute  a

Substantial  Part,  (iv)  whether  any  business  transaction  is one in which a

Related Person has an interest, and (v) such other matters with respect to which

a determination is required under this Article V.


            (d) The  provisions  set forth in this  Article  V,  including  this

paragraph  (d), may not be repealed or amended in any respect unless such action

is approved by the  affirmative  vote of the holders of not less than two-thirds

of the voting power of the outstanding voting shares of the Corporation.


                                   ARTICLE VI


            No director of the Corporation  shall be personally  liable to the

Corporation  or its  shareholders  for monetary  damages for breach of fiduciary

duty as a director;  provided, however, that this Article VI shall not eliminate

or limit the liability of a director to the extent  provided by  applicable  law

(i) for any breach of the director's  duty of loyalty to the  Corporation or its

shareholders,  (ii)  for acts or  omissions  not in good  faith or that  involve

intentional  misconduct  or a knowing  violation  of law,  (iii)  under  section

302A.559 or 80A.23 of the  Minnesota  Statutes,  (iv) for any  transaction  from

which the director derived an improper personal  benefit,  or (v) for any act or

omission  occurring prior to the effective date of this Article VI. No amendment

to or  repeal  of this  Article  VI shall  apply to or have  any  effect  on the

liability or alleged  liability of any director of the  Corporation  for or with

respect  to any  acts or  omissions  of such  director  occurring  prior to such

amendment or repeal.
