ARTICLE I
SHAREHOLDERS: MEETINGS AND VOTING

Section 1.    PLACE OF MEETINGS

        Meetings of the shareholders of WHITE, MACK AND WART, INC. (the Corporation) shall be held at the principal office of the Corporation, or any other place, either within or without the state of Oregon, selected by the Board of Directors.

Section 2.    ANNUAL MEETINGS

        (a)   The annual meeting of the shareholders shall be held on the third Monday in January of each year, if not a legal holiday, and if a legal holiday then on the next succeeding business day, at such time as may be prescribed by the Board of Directors and specified in the notice of the meeting. The Board of Directors shall have the discretion to designate a different annual meeting date for any year provided that the date so designated is within 60 days of the date specified in the preceding sentence. At the annual meeting, the shareholders shall elect by vote a Board of Directors, consider reports of the affairs of the Corporation and transact such other business as may properly be brought before the meeting.

        (b)   If the annual meeting is not held within the earlier of six months after the end of the Corporation's fiscal year or 15 months after its last annual meeting, the circuit court of the county where the Corporation's principal office is located, or, if the principal office is not in Oregon, where the registered office of the Corporation is or was last located, may summarily order a meeting to be held upon the application of any shareholder of the Corporation entitled to participate in an annual meeting.

Section 3.    SPECIAL MEETINGS

        (a)   The Corporation shall hold a special meeting of shareholders upon the call of the President or the Board of Directors, or if the holders of at least 10 percent of all votes entitled to be cast on any issue proposed to be considered at the proposed special meeting sign, date and deliver to the Secretary of the Corporation one or more written demands for the meeting describing the purpose or purposes for which it is to be held.

        (b)   The circuit court of the county where the Corporation's principal office is located, or, if the principal office is not in Oregon, where the registered office of the Corporation is or was last located, may summarily order a special meeting to be held upon the application of a shareholder of the Corporation who signed a valid demand for a special meeting if notice of the special meeting was not given within 30 days after the date the demand was delivered to the Corporation's Secretary or if the special meeting was not held in accordance with the notice.

Section 4.    NOTICE OF MEETINGS

        (a)   The Corporation shall notify shareholders in writing of the date, time and place of each annual and special shareholders meeting not earlier than 60 days nor less than ten days before the meeting date. Except as otherwise required by applicable law or the Articles of Incorporation, the Corporation is required to give notice only to shareholders entitled to vote at the meeting. Such notice is effective when mailed if it is mailed postage prepaid and is correctly addressed to the shareholder's address shown in the Corporation's current record of shareholders. Except as otherwise required by

applicable law or by the Articles of Incorporation, notice of an annual meeting need not include a description of the purpose or purposes for which the meeting is called. Notice of a special meeting shall include a description of the purpose or purposes for which the meeting is called.

        (b)   If an annual or special shareholders meeting is adjourned to a different date, time or place, notice need not be given of the new date, time or place if the new date, time or place is announced at the meeting before adjournment. If a new record date for the adjourned meeting is fixed, or is required by law to be fixed, notice of the adjourned meeting shall be given to persons who are shareholders as of the new record date. 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.

        (c)   A shareholder's attendance at a meeting waives objection to (i) lack of notice or defective notice of the meeting, unless the shareholder at the beginning of the meeting objects to holding the meeting or transacting business at the meeting; and (ii) consideration of a particular matter at the meeting that is not within the purpose or purposes described in the meeting notice, unless the shareholder objects to considering the matter when it is presented.

        (d)   A shareholder may at any time waive any notice required by law, the Articles of Incorporation or these Bylaws. Except as otherwise provided in paragraph (c) of Section 4 of this Article 1, the waiver must be in writing, be signed by the shareholder entitled to the notice, and be delivered to the Corporation for inclusion in the minutes or filing with the corporate records.

Section 5.    QUORUM AND VOTING REQUIREMENTS FOR VOTING GROUPS

        (a)   Shares entitled to vote as a separate voting group may take action on a matter at a meeting only if a quorum of those shares exists with respect to that matter. Unless otherwise required by law, a majority of the votes entitled to be cast on the matter by the voting group constitutes a quorum of that voting group for action on that matter. Once a share is represented for any purpose at a meeting, it is deemed present for quorum purposes for the remainder of the meeting and for any adjournment of that meeting unless a new record date is or must be set for that adjourned meeting.

        (b)   In the absence of a quorum, a majority of those present in person or represented by proxy may adjourn the meeting from time to time until a quorum exists. Any business that might have been transacted at the original meeting may be transacted at the adjourned meeting if a quorum exists.

Section 6.    VOTING RIGHTS

        (a)   The persons entitled to receive notice of and to vote at any shareholders meeting shall be determined from the records of the Corporation on the close of business on the day before the mailing of the notice or on such other date not more than 70 nor less than ten days before such meeting as may be fixed in advance by the Board of Directors.

        (b)   Except as otherwise provided in the Articles of Incorporation or by applicable law and except for the election of directors, each outstanding share, regardless of class, is entitled to one vote on each matter voted on at a shareholders meeting. Only shares are entitled to vote.

        (c)   Except as otherwise provided in the Articles of Incorporation or by applicable law, if a quorum exists, action on a matter, other than the election of directors, by a voting group shall be approved if the votes cast within the voting group favoring the action exceed the votes cast within the voting group opposing the action.

2

        (d)   Except as otherwise provided in the Articles of Incorporation, directors shall be elected by a plurality of the votes cast by holders of the shares entitled to vote in the election at a meeting at which a quorum is present.

Section 7.    VOTING OF SHARES BY CERTAIN HOLDERS

        (a)   If the name signed on a vote, consent, waiver or proxy appointment corresponds to the name of a shareholder, the Corporation, if acting in good faith, is entitled to accept the vote, consent, waiver or proxy appointment and give it effect as the act of the shareholder. If the name signed on a vote, consent, waiver or proxy appointment does not correspond to the name of its shareholder, the Corporation, if acting in good faith, is nevertheless entitled to accept the vote, consent, waiver or proxy appointment and give it effect as the act of the shareholder if:

        (i)    The shareholder is an entity and the name signed purports to be that of an officer or agent of the entity;

        (ii)   The name signed purports to be that of an administrator, executor, guardian or conservator representing the shareholder and, if the Corporation requests, evidence of fiduciary status acceptable to the Corporation has been presented with respect to the vote, consent, waiver or proxy appointment;

        (iii)  The name signed purports to be that of a receiver or trustee in bankruptcy of the shareholder and, if the Corporation requests, evidence of this status acceptable to the Corporation has been presented with respect to the vote, consent, waiver or proxy appointment;

        (iv)  The name signed purports to be that of a pledgee, beneficial owner or attorney-in-fact of the shareholder and, if the Corporation requests, evidence acceptable to the Corporation of the signatory's authority to sign for the shareholder has been presented with respect to the vote, consent, waiver or proxy appointment; or

        (v)   Two or more persons are the shareholder as co-tenants or fiduciaries and the name signed purports to be the name of at least one of the co-owners and the person signing appears to be acting on behalf of all co-owners.

        (b)   Shares of the Corporation are not entitled to be voted if (i) they are owned, directly or indirectly, by another domestic or foreign corporation, and (ii) the Corporation owns, directly or indirectly, a majority of the shares entitled to be voted for directors of such other corporation. This paragraph does not limit the power of a corporation to vote any shares, including its own shares, held by it in a fiduciary capacity.

        (c)   Any redeemable shares that the Corporation may issue are not entitled to be voted after notice of redemption is mailed to the holders and a sum sufficient to redeem the shares has been deposited with a bank, trust company or other financial institution under an irrevocable obligation to pay the holders the redemption price on surrender of the shares.

Section 8.    PROXIES

        A shareholder may vote shares either in person or by proxy. A shareholder may appoint a proxy to vote or otherwise act for the shareholder by signing an appointment form, either personally or by the shareholder's attorney-in-fact. An appointment of a proxy is effective when received by the Secretary or other officer or agent of the Corporation authorized to tabulate votes. An appointment is valid for 11 months unless a longer period is expressly provided in the appointment form. An appointment of a proxy is revocable by the shareholder unless the appointment form conspicuously states that it is irrevocable and the appointment is coupled with an interest.

Section 9.    SHAREHOLDER LISTS

        (a)   After fixing a record date for a meeting, the Corporation shall prepare an alphabetical list of the names of all of its shareholders who are entitled to notice of the meeting. The list shall be arranged by voting group, and within each voting group, by class or series of shares and show the address of and the number of shares held by each shareholder.

        (b)   The shareholder list shall be available for inspection by any shareholder, beginning two business days after notice of the meeting for which the list was prepared is given and continuing through the meeting. Such list shall be kept on file at the Corporation's principal office or at a place identified in the meeting notice in the city where the meeting will be held. A shareholder, or the shareholder's agent or attorney, shall be entitled on written demand to inspect and, subject to the requirements of law, to copy the list during regular business hours and at the shareholder's expense during the period it is available for inspection.

        (c)   The Corporation shall make the shareholder list available at the meeting, and any shareholder, or the shareholder's agent or attorney, is entitled to inspect the list at any time during the meeting or any adjournment.

        (d)   Refusal or failure to prepare or make available the shareholder list does not affect the validity of action taken at the meeting.

        (ii)   the person is or was serving as a fiduciary within the meaning of the Employee Retirement Income Security Act of 1974 with respect to any employee benefit plan of the Corporation or any of its subsidiaries; or

        (iii)  the person is or was serving, at the request of the Corporation or any of its subsidiaries, as a director or officer, or as a fiduciary of an employee benefit plan, of another corporation, partnership, joint venture, trust or other enterprise.

        (i)    furnishes the Corporation a written affirmation of his or her good faith belief that he or she is entitled to be indemnified by the Corporation; and

        (ii)   furnishes the Corporation a written undertaking to repay such advance to the extent that it is ultimately determined by a court that he or she is not entitled to be indemnified by the Corporation.

Section 4.    NONEXCLUSIVITY OF RIGHTS

ARTICLE 9
LIMITATION OF DIRECTOR LIABILITY

        To the fullest extent permitted by law, no director of the Corporation shall be personally liable to the Corporation or its shareholders for monetary damages for conduct as a director. For example, without limiting the generality of the foregoing, if the Oregon Revised Statutes are amended, after this Article 9 becomes effective, to authorize corporate action further eliminating or limiting the personal liability of directors of the Corporation, then the liability of directors of the Corporation shall be eliminated or limited to the fullest extent permitted by the Oregon Revised Statutes, as so amended. No amendment or repeal of this Article 9, nor the adoption of any provision of these Bylaws inconsistent with this Article 9, nor a change in the law, shall adversely affect any right or protection that is based upon this Article 9 and pertains to conduct that occurred prior to the time of such amendment, repeal, adoption or change. No change in the law shall reduce or eliminate the rights and protections set forth in this Article 9 unless the change in the law specifically requires such reduction or elimination.

ARTICLE 10
TRANSACTIONS BETWEEN CORPORATION AND INTERESTED DIRECTORS

Section 1.    VALIDITY OF TRANSACTION

        (a)   No transaction involving the Corporation shall be voidable by the Corporation solely because of a director's direct or indirect interest in the transaction if:

        (i)    The material facts of the transaction and the director's interest were disclosed or known to the Board of Directors or a committee of the Board of Directors, and the Board of Directors or committee authorized, approved or ratified the transaction;

        (ii)   The material facts of the transaction and the director's interest were disclosed or known to the shareholders entitled to vote and a majority of those shareholders authorized, approved or ratified the transaction; or

        (iii)  The transaction was fair to the Corporation.

        (b)   This Article 10 shall not invalidate any contract, transaction or determination that would otherwise be valid under applicable law.

Section 2.    INDIRECT INTEREST

        Solely for purposes of this Article 10, a director of the Corporation has an indirect interest in a transaction if:

        (a)   Another entity in which the director has a material financial interest or in which the director is a general partner is a party to the transaction; or

        (b)   Another entity of which the director is a director, officer or trustee is a party to the transaction and the transaction is or should be considered by the Board of Directors.

Section 3.    AUTHORIZATION BY BOARD

        For purposes of Section 1 of this Article 10, a transaction in which a director has an interest is authorized, approved or ratified by the Board of Directors if it receives the affirmative vote of a majority of the directors on the Board of Directors, or on the committee, who have no direct or indirect interest in the transaction. A transaction may not be authorized, approved or ratified under this Article 10 by a single director. If a majority of the directors who have no direct or indirect interest in the transaction vote to authorize, approve or ratify the transaction, a quorum shall be present for the

13

purpose of taking action under this Article 10. The presence of, or a vote cast by, a director with a direct or indirect interest in the transaction shall not affect the validity of any action taken under Section 1 of this Article 10 by the Board of Directors or a committee thereof, if the transaction is otherwise authorized, approved or ratified as provided in Section 1 of this Article 10.

Section 4.    AUTHORIZATION BY SHAREHOLDERS

        For purposes of Section 1 of this Article 10, a transaction in which a director has an interest is authorized, approved or ratified if it receives the vote of a majority of the shares entitled to be counted under this Article 10, voting as a single voting group. Shares owned by or voted under the control of a director who has a direct or indirect interest in the transaction, and shares owned by or voted under the control of any entity described in paragraph (a) of Section 2 of this Article 10 may be counted in a vote of shareholders to determine whether to authorize, approve or ratify a transaction by vote of the shareholders under Section 1 of this Article 10. A majority of the shares, whether or not present, that are entitled to be counted in a vote on the transaction under this Article 10 constitutes a quorum for the purpose of taking action under this Article 10.
