stated in the notice of the meeting.
Section 1.3. NOTICE OF MEETINGS. Whenever shareholders are required or
permitted to take any action at a meeting, a written notice of the meeting shall
be given which shall state the place, date and hour of the meeting, and, in the
case of a special meeting, the purpose or purposes for which the meeting is
called. Unless otherwise provided by law, the written notice of any meeting
shall be given not less than ten nor more than sixty days before the date of the
meeting to each shareholder entitled to vote at such meeting. If mailed, such
notice shall be deemed to be given when deposited in the United States mail,
postage prepaid, directed to the shareholder at such shareholder's address as it
appears on the records of the Corporation.
Section 1.4. ADJOURNMENTS. Any meeting of shareholders, annual or
special, may be adjourned from time to time, to reconvene at the same or some
other place, and notice need not be given of any such adjourned meeting if the
time and place thereof are announced at the meeting at which the adjournment is
taken. At the adjourned meeting the Corporation may transact any business which
might have been transacted at the original meeting. If the adjournment is for
more than thirty days, or if after the adjournment a new record date is fixed
for the adjourned meeting, a notice of the adjourned meeting shall be given to
each shareholder of record entitled to vote at the meeting.
Section 1.5. QUORUM. At each meeting of shareholder, except where
otherwise provided by law or the articles of incorporation or these by-laws, the
holders of a majority of the outstanding shares of stock entitled to vote on a
matter at the meeting, present in person or represented by proxy, shall
constitute a quorum. In the absence of a quorum of the holders of any class of
stock entitled to vote on a matter, the holders of such class so present or
represented may, by majority vote, adjourn the meeting of such class from time

present or represented. Shares of its own capital stock belonging on the record
date for the meeting to the Corporation or to another corporation, if a majority
of the shares entitled to vote in the election of directors of such other
corporation is held, directly or indirectly, by the Corporation, shall neither
be entitled to vote nor be counted for quorum purposes; provided, however, that
the foregoing shall not limit the right of the Corporation to vote stock,
including but not limited to its own stock, held by it in a fiduciary capacity.
Section 1.6. ORGANIZATION. Meetings of shareholders shall be presided
over by the Chairman of the Board, if any, or in the absence of the Chairman of
the Board by the Vice Chairman of the Board, if any, or in the absence of the

by a Vice President, or in the absence of the foregoing persons by a chairman
designated by the Board of Directors, or in the absence of such designation by a
chairman chosen at the meeting. The Secretary, or in the absence of the

meeting may appoint any person to act as secretary of the meeting.
Section 1.7. VOTING; PROXIES. Unless otherwise provided in the
articles of incorporation, each shareholder entitled to vote at any meeting of
shareholders shall be entitled to one vote for each share of stock held by such
shareholder which has voting power upon the matter in question. Each shareholder
entitled to vote at a meeting of shareholders or to express consent or dissent
to corporate action in writing without a meeting may authorize another person or
persons to act for such shareholder by proxy, but no such proxy shall be voted
or acted upon after three years from its date, unless the proxy provides for a
longer period. A duly executed proxy shall be irrevocable if it states that it
is irrevocable and if, and only as long as, it is coupled with an interest
sufficient in law to support an irrevocable power, regardless of whether the
interest with which it is coupled is an interest in the stock itself or an
interest in the Corporation generally. A shareholder may revoke any proxy which
is not irrevocable by attending the meeting and voting in person or by filing an
instrument in writing revoking the proxy or another duly executed proxy bearing
a later date with the Secretary of the Corporation. Voting at meetings of
shareholders need not be by written ballot and need not be conducted by
inspectors unless the holders of a majority of the outstanding shares of all
classes of stock entitled to vote thereon present in person or represented by
proxy at such meeting shall so determine. Directors shall be elected by a
plurality of the votes of the shares present in person or represented by proxy
at the meeting and entitled to vote on the election of directors. In all other
matters, unless otherwise provided by law or by the articles of incorporation or
these by-laws, the affirmative vote of the holders of a majority of the shares
present in person or represented by proxy at the meeting and entitled to vote on
the subject matter shall be the act of the shareholders. Where a separate vote
by class or classes is required, the affirmative vote of the holders of a
majority of the shares of such class or classes present in person or represented
by proxy at the meeting shall be the act of such class or classes, except as
otherwise provided by law or by the articles of incorporation or these by-laws.

Section 1.8. FIXING DATE FOR DETERMINATION OF SHAREHOLDERS OF RECORD.
In order that the Corporation may determine the shareholders entitled to notice

the date upon which the resolution fixing the record date is adopted by the
Board of Directors, and which record date shall not be more than sixty nor less
than ten days before the date of such meeting. If no record date is fixed by the
Board of Directors, the record date for determining shareholders entitled to

If no record date has been fixed by the Board of Directors and prior action by
the Board of Directors is required by law, the record date for determining
shareholders entitled to consent to corporate action in writing without a
meeting shall be at the close of business on the day on which the Board of
Directors adopts the resolution taking such prior action.
In order that the Corporation may determine the shareholders entitled
to receive payment of any dividend or other distribution or allotment of any
rights or the shareholders entitled to exercise any rights in respect of any
change, conversion or exchange of stock, or for the purpose of any other lawful
action, the Board of Directors may fix a record date, which record date shall
not precede the date upon which the resolution fixing the record date is
adopted, and which record date shall be not more than sixty days prior to such
action. If no record date is fixed, the record date for determining shareholders
for any such purpose shall be at the close of business on the day on which the
Board of Directors adopts the resolution relating thereto.

shall prepare and make, at least ten days before every meeting of shareholders,
a complete list of the shareholders entitled to vote at the meeting, arranged

open to the examination of any shareholder, for any purpose germane to the
meeting, during ordinary business hours, for a period of at least ten days prior
to the meeting, either at a place within the city where the meeting is to be
held, which place shall be specified in the notice of the meeting, or, if not so
specified, at the place where the meeting is to be held. The list shall also be
produced and kept at the time and place of the meeting during the whole time
thereof and may be inspected by any shareholder who is present.

otherwise provided in the articles of incorporation or by law, any action
required by law to be taken at any annual or special meeting of shareholders of
the Corporation, or any action which may be taken at any annual or special
meeting of such shareholders, may be taken without a meeting, without
<Page>
prior notice and without a vote, if a consent or consents in writing, setting
forth the action so taken, shall be signed by the holders of outstanding stock
having not less than the minimum number of votes that would be necessary to
authorize or take such action at a meeting at which all shares entitled to vote
thereon were present and voted and shall be delivered to the Corporation by
delivery to (a) its registered office in the State of Nebraska by hand or by
certified mail or registered mail, return receipt requested, (b) its principal
place of business or (c) an officer or agent of the Corporation having custody
of the book in which proceedings of meetings of shareholders are recorded. Every
written consent shall bear the date of signature of each shareholder who signs
the consent and no written consent shall be effective to take the corporate
action referred to therein unless, within sixty days of the earliest dated
consent delivered in the manner required by this by-law to the Corporation,
written consents signed by a sufficient number of holders to take action are
delivered to the Corporation by delivery to (a) its registered office in the
State of Nebraska by hand or by certified or registered mail, return receipt
requested, (b) its principal place of business, or (c) an officer or agent of
the Corporation having custody of the book in which proceedings of meetings of
shareholders are recorded. Prompt notice of the taking of the corporate action
without a meeting by less than unanimous written consent shall be given to those
shareholders who have not consented in writing.

number. In case at any meeting of the Board a quorum shall not be present, the
members of the Board present may adjourn the meeting from time to time until a
quorum shall be present.

Section 2.9. COMPENSATION OF DIRECTORS. Unless otherwise restricted by
the articles of incorporation or these by-laws, the Board of Directors shall

passed by a majority of the whole Board, designate one or more committees, each
committee to consist of one or more of the directors of the Corporation. The
Board may designate one or more directors as alternate members of any committee,
who may replace any absent or disqualified member at any meeting of the
committee. In the absence of disqualification of a member of a committee, the
member or members thereof present at any meeting and not disqualified from
voting, whether or not such member or members constitute a quorum, may
unanimously appoint another member of the Board to act at the meeting in the
place of any such absent or disqualified member. Any such committee, to the
extent provided in the resolution of the Board of Directors or in these by-laws,
shall have and may exercise all the powers and authority of the Board of
Directors in the management of the business and affairs of the Corporation, and
may authorize the seal of the Corporation to be affixed to all papers which may
require it; but no such committee shall have the power or authority in reference
to amending the articles of incorporation (except that a committee may, to the
extent authorized in the resolution or resolutions providing for the issuance of
shares of stock adopted by the Board of Directors, fix the designations and any
of the preferences or rights of such shares relating to dividends, redemption,
dissolution, any distribution of assets of the Corporation or the conversion
into, or the exchange of such shares for, shares of any other class or classes
or any other series of the same or any other class or classes of stock of the
Corporation or fix the number of shares of any series of stock or authorize the
increase or decrease of the shares of any series), adopting an agreement of
merger or consolidation, recommending to the shareholders the sale, lease or
exchange of all or substantially all of the Corporation's property and assets,
recommending to the shareholders a dissolution of the Corporation or a
revocation of a dissolution, removing or indemnifying directors or amending
these by-laws; and, unless the resolution, these by-laws or the articles of
incorporation expressly so provides, no such committee shall have the power or
authority to declare a dividend, to authorize the issuance of stock or to adopt
a certificate of ownership and merger.
Section 3.2. COMMITTEE RULES. Unless the Board of Directors otherwise
provides, each committee designated by the Board may adopt, amend and repeal
rules for the conduct of its business. In the absence of a provision by the
Board or a provision in the rules of such committee to the contrary, a majority
of the entire authorized number of members of such committee shall constitute a
quorum for the transaction of business, the vote of a majority of the members
present at a meeting at the time of such vote if a quorum is then present shall
be the act of such committee, and in other respects each committee shall conduct
its business in the same manner as the Board conducts its business pursuant to
Article II of these by-laws.
ARTICLE IV: OFFICERS
Section 4.1. OFFICERS; ELECTION. As soon as practicable after the
annual meeting of shareholders in each year, the Board of Directors shall elect
a President and a Secretary, and it may, if it so determines, elect from among

may also elect one or more Vice Presidents, one or more Assistant Vice
Presidents, one or more Assistant Secretaries, a Treasurer and one or more
<Page>
Assistant Treasurers and such other officers as the Board may deem desirable or
appropriate and may give any of them such further designations or alternate
titles as it considers desirable. Any number of offices may be held by the same
person unless the articles of incorporation or these by-laws otherwise provide.
Section 4.2. TERM OF OFFICE; RESIGNATION; REMOVAL; VACANCIES. Unless
otherwise provided in the resolution of the Board of Directors electing any
officer, each officer shall hold office until his or her successor is elected
and qualified or until his or her earlier resignation or removal. Any officer
may resign at any time upon written notice to the Board or to the President or
the Secretary of the Corporation. Such resignation shall take effect at the time
specified therein, and unless otherwise specified therein no acceptance of such
resignation shall be necessary to make it effective. The Board may remove any
officer with or without cause at any time. Any such removal shall be without
prejudice to the contractual rights of such officer, if any, with the
Corporation, but the election of any officer shall not of itself create
contractual rights. Any vacancy occurring in any office of the Corporation by
death, resignation, removal or otherwise may be filled by the Board at any
regular or special meeting.
Section 4.3. POWERS AND DUTIES. The officers of the Corporation shall
have such powers and duties in the management of the Corporation as shall be
stated in these by-laws or in a resolution of the Board of Directors which is
not inconsistent with these by-laws and, to the extent not so stated, as
generally pertain to their respective offices, subject to the control of the
Board. Securities of other corporations held by the Corporation may be voted by
any officer designated by the Board and, in the absence of any such designation,
by the President, any Vice President, the Secretary or the Treasurer. The
Secretary shall have the duty to record the proceedings of the meetings of the
shareholders, the Board of Directors and any committees in a book to be kept for
that purpose. The Board may require any officer, agent or employee to give
security for the faithful performance of his or her duties.

shall be entitled to have a certificate signed by or in the name of the
Corporation by the Chairman or Vice Chairman of the Board of Directors, if any,
or the President or a Vice President, and by the Treasurer or an Assistant
Treasurer, or the Secretary or an Assistant Secretary, of the Corporation,
representing the number of shares of stock in the Corporation owned by such
holder. If such certificate is manually signed by one officer or manually
countersigned by a transfer agent or by a registrar, any other signature on the
certificate may be a facsimile. In case any officer, transfer agent or registrar
who has signed or whose facsimile signature has been placed upon a certificate
shall have ceased to be such officer, transfer agent or registrar before such
certificate is issued, it may be issued by the Corporation with the same effect
as if such person were such officer, transfer agent or registrar at the date of
issue.
Section 5.2. LOST, STOLEN OR DESTROYED STOCK CERTIFICATES; ISSUANCE OF
NEW CERTIFICATES. The Corporation may issue a new certificate of stock in the
place of any certificate theretofore issued by it, alleged to have been lost,
stolen or destroyed, and the Corporation may require the owner of the lost,
stolen or destroyed certificate, or such owner's legal representative, to give
the Corporation a bond sufficient to indemnify it against any claim that may be
made against it on account of the alleged loss, theft or destruction of any such
certificate or the issuance of such new certificate.
ARTICLE VI: MISCELLANEOUS

determined by the Board of Directors.
Section 6.2. SEAL. The Corporation may have a corporate seal which
shall have the name of the Corporation inscribed thereon and shall be in such

corporate seal may be used by causing it or a facsimile thereof to be impressed
or affixed or in any other manner reproduced.
Section 6.3. WAIVER OF NOTICE OF MEETINGS OF SHAREHOLDERS, DIRECTORS
AND COMMITTEES. Whenever notice is required to be given by law or under any
provision of the articles of incorporation or these by-laws, a written waiver
thereof, signed by the person entitled to notice, whether before or after the
time stated therein, shall be deemed equivalent to notice. Attendance of a
person at a meeting shall constitute a waiver of notice of such meeting, except
when the person attends a meeting for the express purpose of objecting, at the
beginning of the meeting, 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 shareholders,
directors or members of a committee of directors need be specified in any
written waiver of notice unless so required by the articles of incorporation or
these by-laws.
<Page>
Section 6.4. INDEMNIFICATION OF DIRECTORS, OFFICERS AND EMPLOYEES. The
Corporation shall indemnify to the full extent permitted by law any person made
or threatened to be made a party to any action, suit or proceeding, whether
civil, criminal, administrative or investigative, by reason of the fact that
such person or such person's testator or intestate is or was a director, officer
or employee of the Corporation or serves or served at the request of the
Corporation any other enterprise as a director, officer or employee. Expenses
incurred by any such person in defending any such action, suit or proceeding
shall be paid or reimbursed by the Corporation promptly upon receipt by it of an
undertaking of such person to repay such expenses if it shall ultimately be
determined that such person is not entitled to be indemnified by the
Corporation. The rights provided to any person by this by-law shall be
enforceable against the Corporation by such person who shall be presumed to have
relied upon it in serving or continuing to serve as a director, officer or
employee as provided above. No amendment of this by-law shall impair the rights
of any person arising at any time with respect to events occurring prior to such
amendment. For purposes of this by-law, the term "Corporation" shall include any
predecessor of the Corporation and any constituent corporation (including any
constituent of a constituent) absolved by the corporation in a consolidation or
merger; the term "other enterprise" shall include any corporation, partnership,
joint venture, trust or employee benefit plan; service "at the request of the
Corporation" shall include service as a director, officer or employee of the
Corporation which imposes duties on, or involves services by, such director,
officer or employee with respect to an employee benefit plan, its participants
or beneficiaries.
Section 6.5. INTERESTED DIRECTORS; QUORUM. No contract or transaction
between the Corporation and one or more of its directors or officers, or between
the Corporation and any other corporation, partnership, association or other
organization in which one or more of its directors or officers are directors or
officers, or have a financial interest, shall be void or voidable solely for
this reason, or solely because the director or officer is present at or
participates in the meeting of the Board of Directors or the committee thereof
which authorizes the contract or transaction, or solely because his or her or
their votes are counted for such purpose, if (1) the material facts as to his or
her relationship or interest and as to the contract or transaction are disclosed
or are known to the Board or the committee, and the Board or the committee in
good faith authorizes the contract or transaction by the affirmative vote of a
majority of the disinterested directors, even though the disinterested directors
be less than a quorum; or (2) the material facts as to his or her relationship
or interest and as to the contract or transaction are disclosed or are known to
the shareholders entitled to vote thereon, and the contract or transaction is
specifically approved in good faith by vote of the shareholders; or (3) the
contract or transaction is fair to the Corporation as of the time it is
authorized, approved or ratified, by the Board, a committee thereof or the
shareholders. Common or interested directors may be counted in determining the
presence of a quorum at a meeting of the Board of Directors or of a committee
which authorizes the contract or transaction.
Section 6.6. FORM OF RECORDS. Any records maintained by the
Corporation in the regular course of its business, including its stock ledger,
books of account and minute books, may be kept on, or be in the form of, punch
cards, magnetic tape, photographs,
<Page>
microphotographs or any other information storage device, provided that the
records so kept can be converted into clearly legible form within a reasonable
time. The Corporation shall so convert any records so kept upon the request of
any person entitled to inspect the same.
Section 6.7. AMENDMENT OF BY-LAWS. These by-laws may be amended or
repealed, and new by-laws adopted, by the Board of Directors, except that
directors may not amend or repeal a by-law which prohibits their doing so, or
adopt a by-law requiring more than a majority of shareholders for a quorum or
action at their meeting, except where the articles of incorporation or law
establish a higher percentage. Notwithstanding the foregoing, a majority of
shareholders entitled to vote may adopt additional by-laws and may amend or
repeal any by-law whether or not adopted by them. As permitted by law, the board
of directors may adopt emergency by-laws that are effective only in a
catastrophic event that prevents a quorum of directors from being readily
assembled. Any such emergency by-laws may make all provisions for running the
Corporation during the emergency, including but not limited to procedures for
calling meeting, quorum requirements and designation of substitute or additional
directors.
