                                     SHARES

      SECTION 4.1. AUTHORIZED CLASS AND NUMBER OF SHARES. The capital stock of
the Corporation shall be of one class and kind, which shall be referred to as
Common Stock. The total number of shares which the Corporation has authority to
issue shall be 10,000,000 shares of Common Stock. The Corporation's shares of
Common Stock do not have any par or stated value except that, solely for the
purpose of any statute or regulation imposing any tax or fee based upon the
capitalization of the Corporation, each of the Corporation's shares of Common
Stock shall be deemed to have a par value of $0.01 per share.

      SECTION 4.2. VOTING RIGHTS OF SHARES. Except as otherwise provided by the
Corporation Law and subject to such shareholder disclosure and recognition
procedures (which may include voting prohibition sanctions) as the Corporation
may by action of its Board of Directors establish, the Corporation's shares of
Common Stock have unlimited voting rights and each outstanding share of Common
Stock shall, when validly issued by the Corporation, entitle the record holder
thereof to one vote at all shareholders' meetings on all matters submitted to a
vote of the shareholders of the Corporation.

      SECTION 4.3. OTHER TERMS OF SHARES. The Corporation's shares of Common
Stock shall be equal in every respect insofar as their relationship to the
Corporation is concerned (but such equality of rights shall not imply equality
of treatment as to redemption or other acquisition of shares by the
Corporation). The holders of shares of Common Stock shall be entitled to share
ratably in such dividends or other distributions (other than purchases,
redemptions or other acquisitions of shares by the Corporation), if any, as are
declared and paid from time to time on the shares at the discretion of the Board
of Directors. In the event of any liquidation, dissolution or winding up of the
Corporation, either voluntary or involuntary, the holders of shares of Common
Stock shall be entitled to share, ratably according to the number of shares of
Common Stock held by them, in all remaining assets of the Corporation available
for distribution to its shareholders.

      Shares of Common Stock of the Corporation purchased, redeemed or otherwise
acquired by it shall constitute authorized but unissued shares, unless prior to
any such purchase redemption or other acquisition, or within thirty (30) days
thereafter, the Board of Directors adopts a resolution providing that such
shares constitute authorized and issued but not outstanding shares.

                                   ARTICLE V

                                    DIRECTORS

      SECTION 5.1. NUMBER. The Board of Directors at the time of adoption of
these Restated Articles of Incorporation by the Board of Directors is composed
of nine (9) members, and the number of Directors shall be fixed by the By-Laws
and may be changed from time to time by amendment to the By-Laws. The By-Laws
may also provide for staggering the terms of the members of the Board of
Directors by dividing the total number of Directors into two (2) or three (3)
groups (with each group containing one-half (1/2) or one-third (1/3) of the
total, as near as may be) whose terms of office expire at different times.

                                      -2-

      SECTION 5.2. VACANCIES. Vacancies occurring in the Board of Directors
shall be filled in the manner for the filling of vacancies, in the manner
provided in the By-Laws or, if the By-Laws do not provide for the filling of
vacancies, in the manner provided by the Corporation Law. The By-Laws may also
provide that in certain circumstances specified therein, vacancies occurring in
the Board of Directors may be filled by vote of the shareholders at a special
meeting called for that purpose or at the next annual meeting of shareholders.

                                   ARTICLE VI

               PROVISIONS RELATING TO BY-LAWS AND INDEMNIFICATION

      SECTION 6.1. BY-LAWS. The Board of Directors shall have the exclusive
power to make, alter, amend or repeal, or to waive provisions of, the By-Laws of
the Corporation by the affirmative vote of a majority of the entire number of
Directors at the time, except as expressly provided by the Corporation Law.

      SECTION 6.2. INDEMNIFICATION OF DIRECTORS, OFFICERS AND OTHER ELIGIBLE
PERSONS.

   (a) To the extent not inconsistent with applicable law, every Eligible Person
shall be indemnified by the Corporation against all Liability and reasonable
Expense that may be incurred by such Eligible Person in connection with or
resulting from any Claim, (i) if such Eligible Person is Wholly Successful with
respect to the Claim, or (ii) if not Wholly Successful, then if such Eligible
Person is determined, as provided in either Section 6.2(f) or 6.2(g), to have
acted in good faith, in what the Eligible Person reasonably believed to be the
best interests of the Corporation or at least not opposed to its best interest
and, in addition, with respect to any criminal claim is determined to have had
reasonable cause to believe that his conduct was lawful or had no reasonable
cause to believe that his conduct was unlawful. The termination of any Claim, by
judgment, order, settlement (whether with or without court approval), or
conviction or upon a plea of guilty or of NOLO CONTENDERE, or its equivalent,
shall not create a presumption that an Eligible Person did not meet the
standards of conduct set forth in clause (ii) of this subsection (a). The
actions of an Eligible Person with respect to an employee benefit plan subject
to the Employee Retirement Income Security Act of 1974 shall be deemed to have
been taken in what the Eligible Person reasonably believed to be the best
interests of the Corporation or at least not opposed to its best interests if
the Eligible Person reasonably believed he was acting in conformity with the
requirements of such Act or he reasonable believed his actions to be in the
interests of the participants in or beneficiaries of the plan.

   (b) The term "Claim" as used in this Section 6.2 shall include every pending,
threatened or completed claim, action, suit or proceeding and all appeals
thereof (whether brought by or in the right of this Corporation or any other
corporation or otherwise), civil, criminal, administrative or investigative,
formal or informal, in which an Eligible Person may become involved, as a party
or otherwise.

                                      -3-

   (c) The term "Eligible Person" as used in this Section 6.2 shall mean every
person (and the estate, heirs and personal representatives of such person) who
is or was a Director, officer, employee or agent of the Corporation or is or was
serving at the request of the Corporation as a foreign or domestic corporation,
partnership, joint venture, trust, employee benefit plan or other organization
or entity whether for profit or not. An Eligible Person shall also be considered
to have been serving an employee benefit plan at the request of the Corporation
if the Eligible Person's duties to the Corporation also imposed duties on, or
otherwise involved services by, the Eligible Person to the plan or to
participants in or beneficiaries of the plan.

   (d) The terms "Liability" and "Expense" as used in this Section 6.2 shall
include, but shall not be limited to, counsel fees and disbursements and amounts
of judgments, fines or penalties against (including excise taxes assessed with
respect to an employee benefit plan), and amounts paid in settlement by or on
behalf of, an Eligible Person.

   (e) The term "Wholly Successful" as used in this Section 6.2 shall mean (i)
termination of any claim against the Eligible Person in question without any
finding of liability or guilt against him, (ii) approval by a court, with
knowledge of the indemnity herein provided, of a settlement of any Claim, or
(iii) the expiration of a reasonable period of time after the making or
threatened making of any Claim without the institution of the same, without any
payment or promise made to induce a settlement.

   (f) Every Eligible Person claiming indemnification hereunder (other than one
who has been Wholly Successful with respect to any Claim) shall be entitled to
indemnification (i) if special independent legal counsel, which may be regular
counsel of the Corporation or other disinterested person or persons, in either
case selected by the Board of Directors, whether or not a disinterested quorum
exists (such counsel or person or persons being hereinafter called the
"Referee"), shall deliver to the Corporation a written finding that such
Eligible Person has met the standards of conduct set forth in Section
6.2(a)(ii), and (ii) if the Board of Directors, acting upon such written
finding, so determines. The Board of Directors shall, if an Eligible Person is
found to be entitled to indemnification pursuant to the preceding sentence, also
determine the reasonableness of the Eligible Person's Expenses.

   (g) If an Eligible Person claiming indemnification pursuant to Section 6.2(f)
is found not to be entitled thereto, or if the Board of Directors fails to
select a Referee under Section 6.2(f) within a reasonable amount of time
following a written request of an Eligible Person for the selection of a
Referee, or if the Referee or the Board of Directors fails to make a
determination under Section 6.2(f) within a reasonable amount of time following
the selection of a Referee, the Eligible Person may apply for indemnification
with respect to a Claim to a court of competent jurisdiction, including a court
in which the Claim is pending against the Eligible Person. On receipt of an
application, the court, after giving notice to the Corporation and giving the
Corporation ample opportunity to present to the court any information or
evidence relating to the claim for indemnification that the Corporation deems
appropriate, may order indemnification if it determines that the Eligible Person
is entitled to indemnification with respect to the Claim because such Eligible
Person met the standards of conduct set forth in Section 6.2(a)(ii). If the
court determines that the Eligible Person is entitled to indemnification, the
court shall also determine the reasonableness of the Eligible Person's Expenses.

                                      -4-

   (h) The rights of indemnification provided in this Section 6.2 shall be in
addition to any rights to which any Eligible Person may otherwise be entitled.
Irrespective of the provisions of this Section 6.2, the Board of Directors may,
at any time and from time to time, (i) approve indemnification of any Eligible
Person to the full extent permitted by the provisions of applicable law at the
time in effect, whether on account of past or future transactions, and (ii)
authorize the Corporation to purchase and maintain insurance on behalf of any
Eligible Person against any Liability asserted against such Eligible Person and
incurred by him in any such capacity, or arising out of the Eligible Person's
status as such, whether or not the Corporation would have the power to indemnify
him against such liability.

   (i) Expenses incurred by an Eligible Person with respect to any Claim, may be
advanced by the Corporation (by action of the Board of Directors, whether or not
a disinterested quorum exists) prior to the final disposition thereof upon
receipt of an undertaking by or on behalf of the Eligible Person to repay such
amount unless he is determined to be entitled to indemnification.

   (j) The provisions of this Section 6.2 shall be deemed to be a contract
between the Corporation and each Eligible Person, and an Eligible Person's
rights hereunder shall not be diminished or otherwise adversely affected by any
repeal, amendment or modification of this Section 6.2 that occurs subsequent to
such person becoming an Eligible Person.

   (k) The provisions of this Section 6.2 shall be applicable to Claims made or
commenced after the adoption hereof, whether arising from acts or omissions to
act occurring before or after the adoption hereof.

                                  ARTICLE VII

                            MISCELLANEOUS PROVISIONS

      SECTION 7.1. AMENDMENT OR REPEAL. Except as otherwise expressly provided
for in these Restated Articles of Incorporation, the Corporation shall be
deemed, for all purposes, to have reserved the right to amend, alter, change or
repeal any provision contained in these Restated Articles of Incorporation to
the extent and in the manner now or hereafter permitted or prescribed by
statute, and all rights herein conferred upon shareholders are granted subject
to such reservations.

      SECTION 7.2. REDEMPTION OF SHARES ACQUIRED IN CONTROL SHARE ACQUISITIONS.
If and whenever the provisions of IC 23-1-42 apply to the Corporation, it is
authorized to redeem its securities pursuant to IC 23-1-42-10.

                                      -5-
