                             SHAREHOLDERS


1.1     Annual Meeting.   The annual meeting of the shareholders 
shall be held on the third Wednesday in the month of May in each 
year at the hour of 3:00 p.m., for the purpose of electing 
directors and transacting such other business as may come before 
the meeting.  If the day fixed for the annual meeting is a legal 
holiday, the meeting shall be held on the next succeeding Friday.

1.2     Failure to Hold Annual Meeting.   If the annual meeting is 
not held at the designated time, the President or the Board of 
Directors may call the annual meeting meeting at a time fixed by 
the calling party not more than 60 days after the designated time 
by proper notice designating the meeting as the annual meeting.  
If the annual meeting is not held at the designated time or during 
the 60-day period thereafter, the annual meeting may be called by 
the holders of not less than one-tenth of all the shares entitled 
to vote at the meeting.  In such event, notice shall be given not 
more than 15 days after the expiration of such 60-day period.  The 
notice shall fix the time of the meeting at the earliest date 
permissible under the applicable notice requirements.

1.3     Special Meetings.   Special meetings of the shareholders 
may be called by the President or by the Board of Directors, and 
shall be called by the President at the request of the holders of 
not less than one-tenth of all the outstanding shares of the 
corporation entitled to vote at the meeting.

1.4     Place of Meetings.   Meetings of the shareholders shall be 
held at the principal business office of the corporation or at 
such other place as may be determined by the Board of Directors.

1.5     Notice of Meetings.  Written or printed notice stating the 
place, day and hour of the meeting and, in case of a special 
meeting, the purpose or purposes for which the meeting is called, 
shall be mailed to each shareholder entitled to vote at the 
meeting at the shareholder's address as it appears on the stock 
transfer records of the corporation, with postage thereon prepaid, 
not less than 10 nor more than 60 days before the date of the 
meeting, by or at the direction of the President, the Secretary or 
the officer or persons calling the meeting.

1.6     Waiver of Notice.   Whenever any notice is required to be 
given to any shareholder of the corporation, a waiver thereof in 
writing, signed by the person or persons entitled to such notice, 
whether before or after the time stated therein, shall be deemed 
equivalent to the giving of such notice.

1.7     Record Date.

              (a)        The Board of Directors may fix a record 
date for the purpose of determining shareholders entitled to 
notice of a shareholders' meeting, to demand a special meeting, to 
vote or to take any other action, which date shall not be more 
than 70 days before the meeting or action requiring a 
determination of shareholders.


              (b)        If no record date is fixed for the 
determination of shareholders entitled to notice of and to vote at 
a shareholders' meeting, the record date shall be the close of 
business on the day before the first notice is delivered to 
shareholders.

              (c)        A determination of shareholders 
entitled to notice of or to vote at a shareholders' meeting is 
effective for any adjournment of the meeting unless the Board of 
Directors fixes a new record date, which it must do if the meeting 
is adjourned to a date more than 120 days after the date fixed for 
the original meeting.

1.8     Voting Records.   The officer or agent having charge of 
the stock transfer books for shares of the corporation shall make, 
at least 10 days before each meeting of shareholders, a complete 
record of the shareholders entitled to vote at such meeting, or 
any adjournment thereof, arranged in alphabetical order, with the 
address of and the number of shares held by each, which record, 
for a period of 10 days prior to such meeting, shall be kept on 
file at the registered office of the corporation and shall be 
subject to inspection by any shareholder at any time during usual 
business hours.  Such record shall also be produced and kept open 
at the time and place of the meeting and shall be subject to the 
inspection of any shareholder during the whole time of the 
meeting.  The original stock transfer book shall be prima facie 
evidence as to who are the shareholders entitled to examine such 
record or transfer books or to vote at any meeting of 
shareholders.  Failure to comply with the requirements of this 
section shall not affect the validity of any action taken at such 
meeting.

1.9     Quorum.   A majority of the outstanding shares of the 
corporation entitled to vote, represented in person or by proxy, 
shall constitute a quorum at a meeting of shareholders.  If a 
quorum is present at a meeting, a majority may adjourn the meeting 
from time to time to a different time and place without further 
notice.  At such adjourned meeting at which a quorum is present, 
any business may be transacted which might have been transacted at 
the meeting as originally held.  The shareholders present at a 
duly organized meeting may continue to transact business until 
adjournment, notwithstanding the withdrawal of enough shareholders 
to leave less than a quorum.

1.10    Manner of Acting.  Unless otherwise required by law or 
the articles of incorporation, any question submitted to the 
shareholders shall be approved if the number of shares voted in 
favor of such question exceeds the number of shares voted in 
opposition.  Any action which is required or permitted to be taken 
by the shareholders at a meeting may be taken without a meeting if 
a consent in writing setting forth the action so taken is signed 
by all of the shareholders entitled to vote on the matter.  The 
action shall be effective on the date when the last signature is 
placed on the consent or at such earlier time as is set forth 
therein.  Such consent, which shall have the same effect as a 
unanimous vote of the shareholders, shall be filed with the 
minutes of the corporation.

1.11     Proxies.   At all meetings of shareholders, a 
shareholder may vote by proxy executed in writing by the 
shareholder or by a duly authorized attorney in fact.  The proxy 
shall be filed with the Secretary of the corporation before or at 
the time of the meeting.  No proxy shall be valid after 11 months 
from the date of its execution, unless otherwise provided in the 
proxy.

1.12     Voting of Shares by Certain Holders.

        (a)        Shares standing in the name of another 
corporation may be voted by such officer, agent or proxy as the 
bylaws of such corporation may prescribe, or, in the absence of 
such provision, as the board of directors of such corporation may 
determine.

        (b)        Shares held be an administrator, executor, 
guardian or conservator may be voted by the holder, either in 
person or by proxy, without a transfer of such shares into the 
holder's name.  Shares standing in the  name of a trustee may be 
voted by that trustee, either in person or by proxy, but no 
trustee shall be entitled to vote shares without a transfer of 
such shares into the trustee's name.

        (c)        Shares standing in the name of a receiver may 
be voted by such receiver, and shares held by or under the control 
of a receiver may be voted by such receiver without the transfer 
thereof into the receiver's name if authority to do so is 
contained in an appropriate order of the court by which such 
receiver was appointed.

        (d)        A shareholder whose shares are pledged shall be 
entitled to vote such shares until the shares have been 
transferred into the name of the pledgee, and thereafter the 
pledgee shall be entitled to vote the shares so transferred.

        (e)        Neither treasury shares, nor shares of its own 
stock held by the corporation in a fiduciary capacity, nor shares 
held by another corporation if a majority of the shares entitled 
to vote for the election of directors of such other corporation is 
held by the corporation, shall be voted at any meeting or counted 
in determining the total number of outstanding shares at any given 
time. 

1.13     Acquisition of Control Shares.  As provided in Section 
10, Chapter 820, Oregon Laws 1987 and to the fullest extent 
permitted by that section, the corporation shall be authorized to 
require a holder of control shares to sell the control shares to 
the corporation for fair value.  The term "control shares" shall 
have the same meaning as that term has in Chapter 820, Oregon Laws 
1987.  The procedures for acquisition of control shares pursuant 
to this section shall be that the Board of Directors shall 
determine the fair value of the control shares and shall give 
notice to the holder of the control shares of the fair value and 
the time at which payment for the control shares will be 
available.  The corporation will then make payment for the control 
shares against delivery of the shares.

                              ARTICLE II

                          BOARD OF DIRECTORS


2.1     General Powers.   The business and affairs of the 
corporation shall be managed by its Board of Directors.

2.2     Number, Tenure and Qualification.   The number of 
directors of the corporation shall be seven.  The directors shall 
hold office until the next annual meeting of shareholders and 
until their successors shall have been elected and qualified.  
Directors need not be residents of the State of Oregon or 
shareholders of the corporation.  The number of directors may be 
increased or decreased from time to time by amendment to the 
bylaws, but no decrease shall have the effect of shortening the 
term of any incumbent director.

2.3     Regular Meetings.   A regular meeting of the Board of 
Directors shall be held without other notice than this bylaw 
immediately after, and at the same place as, the annual meeting of 
shareholders.  The Board of Directors may provide, by resolution, 
the time and place, either within or without the State of Oregon, 
for the holding of additional regular meetings without other 
notice than the resolution.

2.4     Special Meetings.   Special meetings of the Board of 
Directors may be called by or at the request of the President or 
by one-third of the directors.  The person or persons authorized 
to call special meetings of the Board of Directors may fix any 
place, either within or without the State of Oregon, as the place 
for holding any special meeting of the Board of Directors called 
by them.

2.5     Notice.   Written notice of any special meeting of the 
Board of Directors shall be given at least 10 days prior to the 
meeting by personal delivery, by mail or by telegram.  If mailed, 
notice shall be deemed to be given when deposited in the United 
States mails addressed to the director at the director's business 
address, with postage thereon prepaid.  If by telegram, notice 
shall be deemed to be given when the telegram is delivered to the 
telegraph company.  The attendance of a director at a meeting 
shall constitute a waiver of notice of such meeting, except where 
a director attends a meeting for the express purpose of objecting 
to the transaction of any business because the meeting is not 
lawfully called or convened.  Neither the business to be 
transacted at, nor the purpose of, any regular or special meeting 
of the Board of Directors need be specified in the notice or 
waiver of notice of such meeting.

2.6     Waiver of Notice.   Whenever any notice is required to 
be given to any director of the corporation, a waiver thereof in 
writing, signed by the person or persons entitled to such notice, 
whether before or after the time stated therein, shall be deemed 
equivalent to the giving of such notice.

2.7     Quorum.   A majority of the number of directors fixed 
by  Section 2.2 of this Article II shall constitute a quorum for 
the transaction of business at any meeting of the Board of 
Directors.

2.8     Manner of Acting.

       (a)        The act of the majority of the directors 
present at a meeting at which a quorum is present shall be the act 
of the Board of Directors, unless a different number is provided 
by law, the articles of incorporation or these bylaws.

       (b)        Members of the Board of Directors may hold a 
board meeting by conference telephone or similar communications 
equipment by means of which all persons participating in the 
meeting can hear each other.  Participation in such a meeting 
shall constitute presence in person at the meeting.

       (c)        Any action which is required or permitted to be 
taken by the directors at a meeting may be taken without a meeting 
if a consent in writing setting forth the action so taken is 
signed by all of the directors entitled to vote on the matter.  
The action shall be effective on the date when the last signature 
is placed on the consent or at such earlier time as is set forth 
therein.  Such consent, which shall have the same effect as a 
unanimous vote of the directors, shall be filed with the minutes 
of the corporation.

2.9     Vacancies.   Except as hereinafter provided, any 
vacancy occurring in the Board of Directors may be filled by the 
affirmative vote of a majority of the remaining directors though 
less than a quorum of the Board of Directors, or by a sole 
remaining director.  Any directorship to be filled by reason of 
any increase in the number of directors of the corporation fixed 
by the bylaws may be filled by the affirmative vote of a majority 
of the number of directors fixed by the bylaws prior to such 
increase; provided that not more than two such directorships may 
be filled by the directors during any one period between annual 
meetings of the shareholders of the corporation.  Any such 
directorship not so filled by the directors shall be filled by 
election at the next annual meeting of shareholders or at a 
special meeting of shareholders called for that purpose.  A 
director elected to fill a vacancy shall be elected to serve until 
the next annual meeting of shareholders and until a successor 
shall be elected and qualified.

2.10     Compensation.   By resolution of the Board of 
Directors, the directors may be paid their expenses, if any, of 
attendance at each meeting of the Board of Directors, and may be 
paid a fixed sum for attendance at each meeting of the Board of 
Directors or a stated salary as director.  No such payment shall 
preclude any director from serving the corporation in any other 
capacity and receiving compensation therefor.

2.11     Presumption of Assent.   A director of the corporation 
who is present at a meeting of the Board of Directors at which 
action on any corporate matter is taken shall be presumed to have 
assented to the action taken unless the director's dissent to the 
action is entered in the minutes of the meeting or unless a 
written dissent to the action is filed with the person acting as 
the secretary of the meeting before the adjournment thereof or 
forwarded by certified or registered mail to the Secretary of the 
corporation immediately after the adjournment of the meeting.  The 
right to dissent shall not apply to a director who voted in favor 
of the action.

2.12     Transactions with Directors.

        (a)        Any contract or other transaction or 
determination between the corporation and one or more of its 
directors, or between the corporation and another party in which 
one or more of its directors are interested, shall be valid 
notwithstanding the relationship or interest or the presence or 
participation of such director or directors in a meeting of the 
Board of Directors or a committee thereof which acts upon or in 
reference to such contract, transaction, or determination, if:  
the fact of such relationship or interest is disclosed or known to 
the Board of Directors or committee and it authorizes, approves or 
ratifies the contract, transaction or determination by a vote or 
consent sufficient for the purpose without counting the votes or 
consents of such interested directors; or the fact of such 
relationship or interest is disclosed or known to the shareholders 
entitled to vote and they authorize, approve or ratify such 
contract, transaction or determination by vote or written consent; 
or the contract, transaction or determination is fair and 
reasonable to the corporation.

        (b)        Common or interested directors may be counted 
in determining the presence of a quorum at a meeting of the Board 
of Directors or committee which authorizes or ratifies such 
contract, transaction or determination.  The interested directors 
shall not be disqualified from voting as shareholders for 
ratification or approval of such contract, transaction or 
determination.

        (c)        None of the provisions of this section shall 
invalidate any contract, transaction or determination which would 
otherwise be valid under applicable law.

2.13     Removal.   All or any number of the directors may be 
removed, with or without cause, at a meeting called expressly for 
that purpose, by a vote of the holders of a majority of the shares 
then entitled to vote at an election of directors.

                            ARTICLE III

                         EXECUTIVE COMMITTEE

3.1      Designation.   The Board of Directors may designate two 
or more directors to constitute an executive committee.  The 
designation of an executive committee, and the delegation of 
authority to it, shall not operate to relieve the Board of 
Directors, or any member thereof, of any responsibility imposed by 
law.  No member of the executive committee shall continue to be a 
member thereof after ceasing to be a director of the corporation.  
The Board of Directors shall have the power at any time to 
increase or decrease the number of members of the executive 
committee, to fill vacancies thereon, to change any member thereof 
and to change the functions or terminate the existence thereof.

3.2      Powers.   During the interval between meetings of the 
Board of Directors, and subject to such limitations as may be 
imposed by resolution of the Board of Directors, the executive 
committee may have and may exercise all the authority of the Board 
of Directors in the management of the corporation, provided that 
the executive committee shall not have the authority of the Board 
of Directors in reference to amending the articles of 
incorporation; adopting a plan of merger or consolidation; 
recommending to the shareholders the sale, lease, exchange, 
mortgage, pledge or other disposition of all or substantially all 
the property and assets of the corporation otherwise than in the 
usual regular course of its business; recommending to the 
shareholders a voluntary dissolution of the corporation or a 
revocation thereof; or amending the bylaws of the corporation.

3.3      Procedures; Meetings; Quorum.

        (a)        The Board of Directors shall appoint a chairman 
from among the members of the executive committee and shall 
appoint a secretary who may, but need not, be a member of the 
executive committee.  The chairman shall preside at all meetings 
of the executive committee and the secretary of the executive 
committee shall keep a record of its acts and proceedings.

        (b)        Regular meetings of the executive committee, of 
which no notice shall be necessary, shall be held on such days and 
at such places as shall be fixed by resolution adopted by the 
executive committee.  Special meetings of the executive committee 
shall be called at the request of the President or of any member 
of the executive committee, and shall be held upon such notice as 
is required by these bylaws for special meetings of the Board of 
Directors, provided that notice by word of mouth or telephone 
shall be sufficient if received in the city where the meeting is 
to be held not later than the day immediately preceding the day of 
the meeting.

        (c)        Attendance of any member of the executive 
committee at a meeting shall constitute a waiver of notice of the 
meeting.  A majority of the executive committee, from time to 
time, shall be necessary to constitute a quorum for the 
transaction of any business, and the act of a majority of the 
members present at a meeting at which a quorum is present shall be 
the act of the executive committee.  Members of the executive 
committee may hold a meeting of such committee by means of 
conference telephone or similar communications equipment by means 
of which all persons participating in the meeting can hear each 
other, and participation in such a meeting shall constitute 
presence in person at the meeting.

        (d)        Any action which may be taken at a meeting of 
the executive committee may be taken without a meeting if a 
consent in writing setting forth the actions so taken shall be 
signed by all members of the executive committee entitled to vote 
with respect to the subject matter thereof.  The action shall be 
effective on the date when the last signature is placed on the 
consent or at such earlier time as is set forth therein.  The 
consent shall have the same effect as a unanimous vote of the 
executive committee.

        (e)        The Board of Directors may vote to pay the 
members of the executive committee a reasonable fee as 
compensation for attendance at meetings of the executive 
committee.

                            OFFICERS

4.1     Number.   The officers of the corporation shall be a

qualified or until the officer's death, resignation or removal in 
the manner hereinafter provided.

4.3     Removal.   Any officer or agent appointed by the Board 
of Directors may be removed by the Board of Directors whenever in 
its judgment the best interests of the corporation would be served 
thereby, but removal shall be without prejudice to the contract 
rights, if any, of the person so removed.  Appointment of an 
officer or agent shall not of itself create contract rights.

4.4     Vacancies.   A vacancy in any office because of death, 
resignation, removal, disqualification or otherwise, may be filled 
by the Board of Directors for the unexpired portion of the term.

4.5     Chairman of the Board.   The Chairman of the Board of

act of the Executive Vice President, the Vice President (or in the 
event there be more than one Vice President, the Vice Presidents

President, and when so acting shall have all of the powers of, and 
be subject to all the restrictions upon, the Executive Vice 
President.  Any Vice President shall perform such other duties as 
may be assigned from time to time by the President or the Board of 
Directors.

                            ARTICLE V

           INDEMNIFICATION OF OFFICERS, DIRECTORS, EMPLOYEES
                         AND OTHER AGENTS

5.1     Directors and Officers.   The corporation shall 
indemnify its directors and officers to the fullest extent 
permitted by the Oregon Business Corporation Act (Act), as the 
same exists or may hereafter be amended (but, in the case of 
alleged occurrences of actions or omissions preceding any such 
amendment, only to the extent that such amendment permits the 
corporation to provide broader indemnification rights than the Act 
permitted the corporation to provide prior to such amendment).

5.2     Employees and Other Agents.   The corporation shall 
have power to indemnify its employees and other agents as set 
forth in the Act.

5.3     No Presumption of Bad Faith.  The termination of any 
proceeding by judgment, order, settlement, conviction or upon a 
plea of nolo contendere or its equivalent shall not, of itself, 
create a presumption that the person did not act in good faith and 
in a manner which the person reasonably believed to be in or not 
opposed to the best interests of the corporation, and, with 
respect to any criminal proceeding, that the person had reasonable 
cause to believe that the conduct was unlawful.

5.4     Advances of Expenses.   The expenses incurred by a 
director or officer in any proceeding shall be paid by the 
corporation in advance at the written request of the director or 
officer, if the director or officer:

        (a)        furnishes the corporation a written affirmation 
of such person's good faith belief that such person is entitled to 
be indemnified by the corporation; and

        (b)        furnishes the corporation a written undertaking 
to repay such advance to the extent that it is ultimately 
determined by a court that such person is not entitled to be 
indemnified by the corporation.  Such advances shall be made 
without regard to the person's ability to repay such expenses and 
without regard to the person's ultimate entitlement to 
indemnification under this bylaw or otherwise.

5.5     Enforcement.   Without the necessity of entering into 
an express contract, all rights to indemnification and advances 
under this bylaw shall be deemed to be contractual rights and be 
effective to the same extent and as if provided for in a contract 
between the corporation and the director or officer who serves in 
such capacity at any time while this bylaw and relevant provisions 
of the Act and other applicable law, if any, are in effect.  Any 
right to indemnification or advances granted by  this bylaw to a 
director or officer shall be enforceable by or on behalf of the 
person holding such right in any court of competent jurisdiction 
if (a) the claim for indemnification or advances is denied, in 
whole or in part, or (b) no disposition of such claim is made 
within ninety (90) days of request therefor.  The claimant in such 
enforcement action, if successful in whole or in part, shall be 
entitled to be paid also the expense of prosecuting a claim.  It 
shall be a defense to any such action (other than an action 
brought to enforce a claim for expenses incurred in connection 
with any proceeding in advance of its final disposition when the 
required affirmation and undertaking have been tendered to the 
corporation) that the claimant has not met the standards of 
conduct which make it permissible under the Act for the 
corporation to indemnify the claimant for the amount claimed, but 
the burden of proving such defense shall be on the corporation.  
Neither the failure of the corporation (including its Board of 
Directors, independent legal counsel or its shareholders) to have 
made a determination prior to the commencement of such action that 
indemnification of the claimant is proper in the circumstances 
because the claimant has met the applicable standard of conduct 
set forth in the Act, nor an actual determination by the 
corporation (including its Board of Directors, independent legal 
counsel or its shareholders) that the claimant has not met such 
applicable standard of conduct, shall be a defense to the action 
or create a presumption that the claimant has not met the 
applicable standard of conduct.

5.6     Non-Exclusivity of Rights.   The rights conferred on 
any person by this bylaw shall not be exclusive of any other right 
which such 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, both 
as to action in the person's official capacity and as to action in 
another capacity while holding office.  The corporation is 
specifically authorized to enter into individual contracts with 
any or all of its directors, officers, employees or agents 
respecting indemnification and advances, to the fullest extent 
permitted by the law.

5.7     Survival of Rights.   The rights conferred on any 
person by this bylaw shall continue as to a person who has ceased 
to be a director, officer, employee or other agent and shall inure 
to the benefit of the heirs, executors and administrators of such 
a person.

5.8     Insurance.   To the fullest extent permitted by the 
Act, the corporation, upon approval by the Board of Directors, may 
purchase insurance on behalf of any person required or permitted 
to be indemnified pursuant to this bylaw.

5.9     Amendments.   Any repeal of this bylaw shall only be 
prospective and no repeal or modification hereof shall adversely 
affect the rights under this bylaw  in effect at the time of the 
alleged occurrence of any action or omission to act that is the 
cause of any proceeding against any agent of the corporation.

5.10    Savings Clause.   If this bylaw or any portion hereof 
shall be invalidated on any ground by any court of competent 
jurisdiction, the corporation shall indemnify each director, 
officer or other agent to the fullest extent permitted by any 
applicable portion of this bylaw that shall not have been 
invalidated, or by any other applicable law.

5.11    Certain Definitions.   For the purposes of this bylaw, 
the following definitions shall apply:

        (a)           The term "proceeding" shall be broadly 
construed and shall include, without limitation, the 
investigation, preparation, prosecution, defense, settlement and 
appeal of any threatened, pending or completed action, suit or 
proceeding, whether civil, criminal, administrative or 
investigative.

        (b)           The term "expenses" shall be broadly 
construed and shall include, without limitation, expense of 
investigations, judicial or administrative proceedings or appeals, 
attorneys' fees and disbursements and any expenses of establishing 
a right to indemnification under Section 5.5 of this bylaw, but 
shall not include amounts paid in settlement, judgments or fines.

        (c)          The term "corporation" shall include, in 
addition to the resulting or surviving corporation, any 
constituent corporation (including any constituent of a 
constituent) absorbed in a consolidation or merger which, if its 
separate existence had continued, would have had power and 
authority to indemnify its directors, officers, employees or 
agents, so that any person who is or was a director, officer, 
employee or agent of such constituent corporation, or is or was 
serving at the request of such constituent corporation as a 
director, officer, employee or agent of another corporation, 
partnership, joint venture, trust or other enterprise, shall stand 
in the same position under the provisions of this bylaw with 
respect to the resulting or surviving corporation as the person 
would have with respect to such constituent corporation if its 
separate existence had continued.

        (d)           References to a "director," "officer," 
"employee," or "agent" of the corporation shall include, without 
limitation, situations where such person is serving at the request 
of the corporation as a director, officer, employee, trustee or 
agent of another corporation, partnership, joint venture, trust or 
other enterprise.

        (e)          References to "other enterprises" shall 
include employee benefit plans; references to "fines" in the Act 
shall include any excise taxes assessed on a person with respect 
to an employee benefit plan; and references to "serving at the 
request of the corporation" shall include any service as a 
director, officer, employee or agent of the corporation which 
imposes duties on, or involves services by, such director, 
officer, employee, or agent with respect to an employee benefit 
plan, its participants, or beneficiaries; and a person who acted 
in good faith and in a manner the person  reasonably believed to 
be in the interest of the participants and beneficiaries of an 
employee benefit plan shall be deemed to have acted in a manner 
"not opposed to the best interests of the corporation" as referred 
to in this bylaw.


                            ARTICLE VI

              CERTIFICATES FOR SHARES AND THEIR TRANSFER

6.1     Certificates for Shares.

        (a)        Certificates representing shares of the 
corporation shall be in such form as shall be determined by the 
Board of Directors.  Such certificates shall be signed by the 
President or a Vice President and by the Secretary or an Assistant 
Secretary and may be sealed with the seal of the corporation or a 
facsimile thereof.  All certificates for shares shall be 
consecutively numbered or otherwise identified.

        (b)        The name and address of the person to whom the 
shares represented thereby are issued, with the number of shares 
and date of issue, shall be entered on the stock transfer books of 
the corporation.  All certificates surrendered to the corporation 
for transfer shall be cancelled and no new certificate shall be 
issued until the former certificate for a like number of shares 
shall have been surrendered and cancelled, except that in case of 
a lost, destroyed or mutilated certificate a new one may be issued 
therefor upon such terms and indemnity to the corporation as the 
Board of Directors may prescribe.

6.2     Transfer of Shares.   Transfer of shares of the 
corporation shall be made only on the stock transfer books of the 
corporation by the holder of record thereof or by the holder's 
legal representative, who shall furnish proper evidence of 
authority to transfer, or by the holder's attorney thereunto 
authorized by power of attorney duly executed  and filed with the 
Secretary of the corporation.  The person in whose name shares 
stand on the books of the corporation shall be deemed by the 
corporation to be the owner thereof for all purposes.

6.3     Transfer Agent and Registrar.   The Board of Directors 
may from time to time appoint one or more Transfer Agents and one 
or more Registrars for the shares of the corporation, with such 
powers and duties as the Board of Directors shall determine by 
resolution.  The signatures of the President or Vice President and 
the Secretary or Assistant Secretary upon a certificate may be 
facsimiles if the certificate is manually signed on behalf of a 
Transfer Agent or by a Registrar other than the corporation itself 
or an employee of the corporation.

6.4     Officer Ceasing to Act.   In case any officer who has 
signed or whose facsimile signature has been placed upon a stock 
certificate shall have ceased to be such officer before such 
certificate is issued, it may be issued by the corporation with 
the same effect as if the signer were such officer at the date of 
its issuance.

6.5     Fractional Shares.   The corporation shall not issue 
certificates for fractional shares.

7.3     Checks, Drafts, etc.   All checks, drafts or other
