shareholders, any officer entitled to preside at, or to act as Secretary of,

in the election of Directors ("Voting Stock"), by the Corporation's Chairman 
of the Board, by its President or by the Board of Directors pursuant to a

Corporation Act, (the "Act") as the same exists or may hereafter be amended, 
a director of the Corporation shall not be liable to the Corporation or its

for or with respect to any acts or omissions of such director occurring prior
to such amendment or repeal. 

Page 3

 
	5.2  Restriction on Amendment 
 
	In addition to any requirements of law and any other provisions 
herein or in the terms of any class or series of stock having a preference

affirmative vote of the holders of two-thirds or more of the voting power of 
the then outstanding Voting Stock, voting together as a single class, shall 
be required to amend, alter or repeal any provision of this Article V. 
 
             ARTICLE VI  INDEMNIFICATION OF DIRECTORS, OFFICERS, 
                             EMPLOYEES AND AGENTS  
 
     1.  The Corporation shall have the following powers: 
 
         (a)	The Corporation may indemnify and hold harmless to the 
fullest extent not prohibited by applicable law each person who was or is 
made a party to or is threatened to be made a party to or is involved 
(including, without limitation, as a witness) in any actual or threatened 
action, suit or other proceeding, whether civil, criminal, derivative, 
administrative or investigative, by reason of that fact that he or she is or 
was a director, officer, employee or agent of the Corporation or, being or 
having been such a director, officer, employee or agent of the Corporation, 
he or she is or was serving at the request of the Corporation as a director, 
officer, employee, agent, trustee, or in any other capacity of another 
corporation or of a partnership, joint venture, trust or other enterprise, 
including service with respect to employee benefit plans, whether the 
basis of such proceeding is alleged action or omission in an official 
capacity or in any other capacity while serving as a director, officer, 
employee, agent trustee or in any other capacity, against all expense, 
liability and loss (including, without limitation, attorneys' fees, 
judgments, fines, ERISA excise taxes or penalties and amounts to be paid in 
settlement) actually or reasonably incurred or suffered by such person in 
connection therewith.  Such indemnification may continue as to a person who 
has ceased to be a director, officer, employee or agent of the Corporation 
and shall inure to the benefit of his or her heirs and personal 
representatives. 
 
         (b)	The Corporation may pay expenses incurred in defending 
any such proceeding in advance of the final disposition of any such 
proceeding; provided, however, that the payment of such expenses in advance 
of the final disposition of a proceeding shall be made to or on behalf of a 
director, officer, employee or agent only upon delivery to the Corporation of 
an undertaking, by or on behalf of such director, officer, employee or agent, 
to repay all amounts so advanced if it shall ultimately be determined that 
such director, officer, employee or agent is not entitled to be indemnified 

Page 4


under this Article VI or otherwise, which undertaking may be unsecured 
and may be accepted without reference to financial ability to make repayment. 
 
         (c)	The Corporation may enter into contracts with any person 
who is or was a director, officer, employee and agent of the Corporation in 
furtherance of the provisions of this Article VI and may create a trust fund, 
grant a security interest in property of the Corporation, or use other means 
(including, without limitation, a letter of credit) to ensure the payment of 
such amounts as may be necessary to effect indemnification as provided in 
this Article VI. 
 
         (d)	If the Act is amended in the future to expand or increase the 
power of the Corporation to indemnify, to pay expenses in advance of final 
disposition, to enter into contracts, or to expend or increase any similar 
or related power, then, without any further requirement of action by the 
shareholders or directors of the Corporation, the powers described in this 
Article VI shall be expanded and increased to the fullest extent permitted 
by the Act, as so amended. 
 
         (e)	No indemnification shall be provided under this Article VI 
to any such person if the Corporation is prohibited by the nonexclusive 
provisions of the Act or other applicable law as then in effect from paying 
such indemnification.  For example, no indemnification shall be provided to 
any director in respect of any proceeding, whether or not involving action 
in his or her official capacity, in which he or she shall have been finally 
adjudged to be liable on the basis of intentional misconduct or knowing 
violation of law by the director, or from conduct of the director in 
violation of Section 23B.08.310 of the Act, or that the director personally 
received a benefit in money, property or services to which the director was 
not legally entitled. 
 
     2.	The Corporation shall indemnify and hold harmless any person 
who is or was a director or officer of the Corporation, and pay expenses in 
advance of final disposition of a proceeding, to the full extent to which the 
Corporation is empowered. 
 
     3.	The Corporation may, by action of its Board of Directors from time 
to time, indemnify and hold harmless any person who is or was an employee or 
agent of the Corporation, and pay expenses in advance of final disposition of a 
proceeding, to the full extent to which the Corporation is empowered, or to a 
lesser extent which the Board of Directors may determine. 
 
     4.	The rights to indemnification and payment of expenses in advance 
of final disposition of a proceeding conferred by or pursuant to this 
Article VI shall be contract rights. 
 
Page 5



     5.	A director, officer, employee or agent ("claimant") shall be 
presumed to be entitled to indemnification and/or payment of expenses under 
this Article VI upon submission of a written claim (and, in an action brought
to enforce a claim for expenses incurred in defending any proceeding in 
advance of its final disposition, where the undertaking in subsection 1(b) 
above has been delivered to the Corporation) and thereafter the Corporation 
shall have the burden of proof to overcome the presumption that the claimant 
is so entitled. 
 
     If a claim under this Article is not paid in full by the Corporation 
within sixty (60) days after a written claim has been received by the 
Corporation, except in the case of a claim for expenses incurred in defending
a proceeding in advance of its final disposition, in which case the 
applicable period shall be twenty (20) days, the claimant may at any time 
thereafter bring suit against the Corporation to recover the unpaid amount of
the claim and, to the extent successful in whole or in part, the claimant 
shall be entitled to be paid also the expense of prosecuting such claim.  
Neither the failure of the Corporation (including its board of directors, 
its shareholders or independent legal counsel) to have made a determination 
prior to the commencement of such action that indemnification of or 
reimbursement or advancement of expenses to the claimant is proper in the 
circumstances nor an actual determination by the Corporation (including its 
board of directors, its shareholders or independent legal counsel) that the 
claimant is not entitled to indemnification or to the reimbursement or 
advancement of expenses shall be a defense to the action or create a 
presumption that the claimant is not so entitled. 
 
     6.	The right to indemnification and payment of expenses in advance 
of final disposition of a proceeding conferred in this Article shall not be 
exclusive of any other right which any person may have or hereafter acquire 
under any statute, provision of the Articles of Incorporation, Bylaws, 
agreement, vote of shareholders or disinterested directors or otherwise. 
 
     7.	The Corporation may purchase and maintain insurance, at its 
expense, to protect itself and any director, officer, employee, agent or 
trustee of the Corporation or another corporation, partnership, joint venture, 
trust or other  enterprise against any expense, liability or loss, whether or
not the corporation would have the power to indemnify such person against 
such expense, liability or loss under the Act. 
 
     8.	Any repeal or modification of this Article VI shall not adversely 
affect any right of any person existing at the time of such repeal or 
modification. 
 
     9.	If any provision of this Article VI or any application thereof 
shall be invalid, unenforceable or contrary to applicable law, the remainder 
of 

Page 6


this Article VI, or the application of such provision to persons or 
circumstances other than those as to which it is held invalid, unenforceable 
or contrary to applicable law, shall not be affected thereby and shall 
continue in full force and effect. 
 
     10.	For the purposes of this Article VI, "applicable law" shall at 
all times be construed as the applicable law in effect at the date 
indemnification may be sought, or the law in effect at the date of the 
action, omission or other event giving rise to the situation for which 
indemnification may be sought, whichever is selected by the person seeking 
indemnification.  As of the date hereof, applicable law shall include 
Section 23B.08.500 through .600 of the Act. 
 
 
                     ARTICLE VII  DIRECTORS AND OFFICERS   
 
      7.1  Number of Directors 
 
     The number of directors of the Corporation shall be specified in 
the Bylaws, and such number may from time to time be increased or decreased 
in such manner as may be prescribed in the Bylaws.  The officers of the 
Corporation shall be appointed in such manner as described in the Bylaws. 
 
     7.2  Election of Directors 
 
     Unless otherwise provided for pursuant to the authority granted in 
Section 3.2 of Article III hereof, shareholders of the Corporation shall not 
have the right to cumulative votes in the election of directors. 
 
 
                    ARTICLE VIII.  MERGERS, SHARE EXCHANGES  
                            AND OTHER TRANSACTIONS 
 
     Except as otherwise expressly provided in these Articles of 
Incorporation, a merger, share exchange, sale of substantially all of the 
Corporation's assets other than in the regular course of business, or 
dissolution must be approved by the affirmative vote of a majority of the 
Corporation's outstanding shares entitled to vote, or if separate voting by 
voting groups is required, then by not less than a majority of all the votes 
entitled to be cast by that voting group. 

 
             ARTICLE IX.  CORPORATION'S ACQUISITION OF OWN SHARES 
 
     The Corporation may purchase, redeem receive, take or otherwise 
acquire, own and hold, sell, lend, exchange, transfer or otherwise dispose 
pledge, use and otherwise deal with and in its own shares.  As a specific 
modification of Section 23B.06.310 of the Act, pursuant to the authority in

Page 7

 
Section 23B.02.020(5)(c) of the Act to include provisions related to the 
management of the business and the regulation of the affairs of the 
Corporation, shares of the Corporation's stock acquired by it shall be 
considered "Treasury Stock" and so held by the Corporation.  The shares so 
acquired by the Corporation shall not be considered as authorized but 
unissued but rather authorized, issued and held by the Corporation but not 
outstanding.  The shares so acquired shall not be regarded as canceled or as 
a reduction to the authorized capital of the Corporation unless specifically 
so designated by the Board of Directors in an amendment to these Articles of 
Incorporation.  The provisions of this Article IX do not alter or affect the 
status of the Corporation's acquisition of its shares as a 
"distribution" by the Corporation as defined in Section 23B.01.400(6) of the 
Act nor alter or affect the limitations of distributions by the Corporation 
set forth in Section 23B.06.400 of the Act.  Any shares so acquired the 
Corporation, unless specifically designated by the Board of Directors, at 
the time of acquisition, shall be considered on subsequent disposition as 
transferred rather than reissued.  Nothing in this Article IX limits or 
restricts the right of the Corporation to resell or otherwise dispose of any 
of its shares previously acquired for such consideration and according to 
such procedures as established by the Board of Directors.
