shall be held on the first Tuesday in the month of May at the hour of three
o'clock p.m., or such other time as may be determined by resolution of the Board
of Directors, beginning with the year 1986, for the purpose of electing
Directors and for the transaction of such other business as may come before the

State of Oklahoma, such meeting shall be held on the next succeeding business
day. If the election of Directors shall not be held on the day designated herein
for any annual meeting of the shareholders, or at any adjournment thereof, the
Board of Directors shall cause the election to be held at a special meeting of
the shareholders as soon thereafter as conveniently may be.

            SECTION 2. Special Meeting. Special meetings of the shareholders for
any purpose or purposes, unless otherwise prescribed by statute, may be called
by the President or by the Board of Directors.

            SECTION 3. Place of Meeting. The Board of Directors may designate
any place, either within or without the State of Oklahoma, unless otherwise
prescribed by statute, as the place of meeting for any annual meeting or for any
special meeting called by the Board of Directors. A waiver of notice signed by
all shareholders entitled to vote at a meeting may designate any place, either
within or without the State of Oklahoma, unless otherwise prescribed by statute,
as the place for the holding of such meeting. If no designation is made, or if a
special meeting be otherwise called, the place of meeting shall be the principal
office of the Corporation in the State of Oklahoma.

            SECTION 4. Notice of Meeting. Written or printed notice stating the
place, day and hour of the meeting and, in case of a special meeting or if
otherwise required by law, the purpose or purposes for which the meeting is
called, shall be delivered not less than three nor more than sixty (60) days
before the date of the meeting either personally or by mail, by or at the
direction of the President or the Secretary, or the office or persons calling
the meeting, to each shareholder of record entitled to vote at such meeting. If
mailed, such notice shall be deemed to be delivered when deposited in the United
States mail, addressed to the shareholder at his address as it appears on the
transfer books of the Corporation, with postage thereon prepaid.

            SECTION 5. Fixing of Record Date. For the purpose of determining
shareholders entitled to notice of or to vote at any meeting of shareholders or
any adjournment thereof, or shareholders entitled to receive payment of any
dividend, or in order to make a determination of shareholders for any other
proper purpose, the Board of Directors may fix a time, not exceeding sixty (60)
days preceding the date of any meeting of shareholders or the day fixed for the
payment of any dividend or distribution or the date for the allotment of rights
or the date when any change or conversion or exchange of shares shall be made or
go



Bylaws of O.I. Corporation                                                     2


into effect, as a record date for the determination of the shareholders
entitled to notice of and to vote at such meeting or entitled to receive
payments of any such dividend, distribution, or allotment of rights, or to
exercise rights in respect to any such change, conversion, or exchange of
shares. In the event a record date shall have been fixed as aforesaid for any
specified purpose, the stock transfer books of the Corporation shall not be
closed in connection therewith.

            SECTION 6. Voting Lists. The officer or agent having charge of the
stock ledger of the Corporation shall make, at least two full days before each
meeting of the shareholders, a complete list 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 shareholder,
which list, together with the stock ledger, or a duplicate thereof, shall be
kept at the place of such meeting for a period of one full day prior to the
convening of such meeting, and shall be subject to inspection at any time during
such period by any shareholder or person representing any shareholder.
Notwithstanding the foregoing, in the event the original or duplicate stock
ledger reasonably shows in understandable form all persons entitled to represent
shares at such meeting with the number of shares entitled to be voted by each
shareholder, it shall not be necessary to prepare and produce the list of
shareholders herein above referred to.

            SECTION 7. 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 less than a majority of the
outstanding shares are represented at meeting, a majority of the shares so
represented may adjourn the meeting from time to time for not more than a total
of twenty-nine (29) days without further notice. At such adjourned meeting at
which a quorum shall be present or represented, any business may be transacted
which might have been transacted at the meeting as originally notified. 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. Any previously scheduled annual or
special meeting, may be postponed by resolution of the Board of Directors upon
public notice given prior to the date previously scheduled for such meeting. In
addition, annual or special meetings of the shareholders may be adjourned,
whether or not a quorum is present, by the President or pursuant to a resolution
of the Board of Directors. A share shall be treated as being present at a
meeting if the holder of such share is (i) present in person at the meeting; or
(ii) represented at the meeting by a valid proxy, whether the instrument
granting such proxy is marked as casting of vote or abstaining, is left blank or
does not empower such proxy to vote with respect to some or all matters to be
voted upon at the meeting.

            SECTION 8. Proxies. At all meetings of shareholders, a shareholder
may vote in person or by proxy in a dated, written appointment signed by the
shareholder, which appointment shall be filed with the Secretary of the
Corporation at or before the meeting at which the shares are to be voted.

            SECTION 9. Voting of Shares. Each outstanding share entitled to vote
shall be entitled to one vote upon each matter submitted to a vote at meeting of
shareholders. The voting of shares held otherwise than by an individual shall be
governed by the provisions of the Oklahoma Business Corporation Act. In
determining the number of shares entitled to vote on any matter, shares not
voted on a matter (including elections) will not be treated as entitled to vote.

            SECTION 10. Consent and Waiver of Notice.

            (a) Any transactions of the shareholders of the Corporation at any
meeting thereof, regardless how or whether call was made or notice given, shall
be as valid as though transacted at a meeting duly held after regular call and
notice:

                                  thereafter approved and ratified at a regular
                                  or special shareholders' meeting held upon
                                  regular call or notice; or

                      (ii)        if a quorum be present either in person or by
                                  proxy and if, either before or after the
                                  meeting, each of the shareholders entitled to
                                  vote and not present in person or by proxy
                                  sign a written waiver of notice, or a consent
                                  to the holding of such meeting, or any
                                  approval of the minutes thereof. All such
                                  waivers, consents or approvals shall be filed
                                  with the Secretary or made a part of the

            (b) A waiver of notice, in writing, signed by the person or persons
entitled to such notice, whether signed before or after the time stated therein,
shall be deemed equivalent to the actual giving of any such notice required by
the Oklahoma Business Corporation Act, the Articles of Incorporation of this
Corporation or by these Bylaws.

            (c) Any action which pursuant to the Oklahoma Business Corporation
Act, the Articles of Incorporation of this Corporation or these Bylaws which
might be taken at a meeting of the shareholders, may be taken without a meeting
if a record or memorandum thereof be made in writing and signed by all of the
holders of shares who would be entitled to vote at meeting for such purpose and
such record or memorandum be filed with the Secretary of the Corporation and
made a part of the corporate records.

Incorporation, the number of Directors may be increased to as many as (13) or
decreased to as few as three (3) by resolutions adopted 80% or more of the

least three days prior thereto by written notice delivered personally or mailed
to each director at his business address, or by telegram. Such notice shall
specify the time, place and purpose of the meeting. If mailed, such notice shall

the Directors may be paid their expenses, if any, of attendance at each meeting

payment shall preclude any Director from serving the Corporation in any other
capacity and receiving compensation therefor.

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 his dissent shall be entered in the minutes of the meeting or unless he
shall file his written dissent to such action with the person acting as the
secretary of the meeting before the adjournment thereof or shall forward such
dissent by registered mail to the Secretary of the Corporation within two days
after the adjournment of the meeting. No director who voted in favor of such
action at the meeting shall have any right to dissent from such action.

            SECTION 11. Executive Committee. The Board of Directors, by
resolution adopted by a majority of the entire Board, may designate two or more
directors to constitute an Executive Committee, which committee shall have and
exercise all of the authority of the Board of Directors in the management of the

Committee shall act only in the interval between meetings of the Board of

            SECTION 12. Action Without Meeting. Any action which might be taken
at a meeting of the Board of Directors or of the Executive Committee may be
taken without a meeting if a record or memorandum thereof be made in writing and
signed by all of the members of the Board of Directors or the Executive
Committee, as the case may be, and such record or memorandum is filed with and
made a part of the permanent records of the Corporation.

            SECTION 13. Other Committees. In addition to the Executive Committee
which may be established pursuant to Section 11 of this Article III, the Board
of Directors, by resolution adopted by a majority of the entire Board, may

officer shall hold office until his successor shall have been duly elected and
shall have qualified or until his death or until he shall resign or shall have
been removed in the manner hereinafter provided.

            SECTION 3. Removal. Any officer or agent elected or 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 such
removal shall be without prejudice to the contract rights, if any, of the person
so removed.

powers of and be subject to all the restrictions upon the President. The Vice
President shall perform such other duties as from time to time may be assigned
to him by the President or by the Board of Directors. If there be more than one
Vice President, this Section shall apply to such Vice Presidents in the same

            a) The Corporation shall indemnify any person who was or is a party
or is threatened to be made a party to any threatened, pending or completed
action, suit or proceeding, whether civil, criminal, administrative or
investigative (other than an action by or in the right of the Corporation) by
reason of the fact that such person is or was, at any time prior to or during
which this Article XI is in effect, a director, officer, employee or agent of
the Corporation, or is or was, at any time prior to or during which this Article
XI is in effect, serving at the request of the Corporation as a director,
officer, employee or agent of another Corporation, partnership, joint venture,
trust, other enterprise or employee benefit plan against reasonable expenses
(including attorneys' fees), judgments, fines, penalties, amounts paid in
settlement and other liabilities actually and reasonably incurred by such person
in connection with such action, suit or proceeding if such person acted in good
faith and in a manner he reasonably believed to be in or not opposed to the best
interests of the Corporation, and, with respect to any criminal action or
proceeding, has no reasonable cause to believe that his conduct was unlawful.
The termination of any action, suit or proceeding by judgment, order,
settlement, conviction or upon a plea of nolo contendere or its equivalent,
shall not, of itself, create a presumption that such person did not act in good
faith and in a manner which he reasonably believed to be in or not opposed to
the best interests of the Corporation, and, with respect to any criminal action
or proceeding, had reasonable cause to believe that his conduct was unlawful.

            b) The Corporation shall indemnify any person who was or is a party
or is threatened to be made a party to any threatened, pending or completed
action or suit by or in the right of the Corporation to procure judgment in its
favor by reason of the fact that such person is or was, at any time prior to or
during which this Article XI is in effect, a director, officer, employee or
agent of the Corporation, or is or was, at any time prior to or during which
this Article XI is in effect, serving at the request of the Corporation as a

Bylaws of O.I. Corporation                                                    11



director, officer, employee or agent of another Corporation, partnership, joint
venture, trust or other enterprise against expenses (including attorneys' fees),
actually and reasonably incurred by such person in connection with the defense
or settlement of such action or suit if such person acted in good faith and in a
manner he reasonably believed to be in or not opposed to the best interests of
the Corporation; provided, that no indemnification shall be made under this
sub-section (b) in respect of any claim, issue or matter as to which such person
shall have been adjudged to be liable to the Corporation unless and only to the
extent that a court of appropriate jurisdiction shall determine upon application
that, despite the adjudication of liability but in view of all the circumstances
of the case, such person is fairly and reasonably entitled to indemnity of such
expenses which the court of appropriate jurisdiction shall deem proper.

            c) Any indemnification under sub-sections (a) or (b) (unless ordered
by a court of appropriate jurisdiction) shall be made by the Corporation only as
authorized in the specific case upon a determination that indemnification of
such person is proper in the circumstances because he has met the applicable
standard of conduct set forth in sub-sections (a) and (b). Such determination
shall be made (1) by the Board of Directors by a majority vote of a quorum
consisting of directors not parties to such action, suit or proceeding; or (2)
if such a quorum is not obtainable, or, even if obtainable a quorum of
disinterested directors so directs, by independent legal counsel, in written
opinion, selected by the Board of Directors; or (3) by the shareholders. In the
event a determination is made under this sub-section (c) that the director,
officer, employee or agent has met the applicable standard of conduct as to some
matters but not as to others, amounts to be indemnified may be reasonably
prorated.

            d) Expenses incurred by a person who is or was a director or officer
of the Corporation in appearing at, participating in or defending any
threatened, pending or completed action, suit or proceeding, whether civil,
criminal, administrative or investigative, shall be paid by the Corporation at
reasonable intervals in advance of the final disposition of such action, suit or
proceeding upon receipt of any undertaking by or on behalf of the director or
officer to repay such amount if it shall ultimately be determined that he is not
entitled to be indemnified by the Corporation as authorized by this Article XI.

            e) It is the intention of the Corporation to indemnify the persons
referred to in this Article XI to the fullest extent permitted by law and with
respect to any action, suit or proceeding arising from events which occur at any
time prior to or during which this Article XI is in effect. The indemnification
provided herein shall be applicable whether or not negligence or gross
negligence of the persons referred to in this Article XI is alleged or proven.
The indemnification and advancement of expenses provided by this Article XI
shall not be deemed exclusive of any other rights to which those seeking
indemnification or advancement of expenses may be or become entitled under any
laws, the Certification of Incorporation, these Bylaws, agreement, the vote of
shareholders or disinterested directors or otherwise, or under any policy or
policies of insurance purchased and maintained by the Corporation on behalf of
any such person, both as to action in his official capacity and as to action in
another capacity while holding such office, and shall continue as to a person
who has ceased to be a director, officer, employee or agent and shall inure to
the benefit of the heirs, executors and administrators of such person.

            f) The indemnification provided by this Article XI shall be subject
to all valid and applicable laws, and, in the event this Article or any of the
provisions hereof or the indemnification contemplated hereby are found to be
inconsistent with or contrary to any such valid laws, the latter shall be deemed
to control and this Article XI shall be regarded as modified accordingly, and,
as so modified, to continue in full force and effect.
