the meeting or (ii) by any shareholder who is a holder of record at the time of
the giving of the notice provided for in this Section 12, who is or will be
entitled to vote at the meeting and who complies with the procedures set forth

      For business (other than the nomination or election of directors) properly
to be brought before an annual meeting by a shareholder, the shareholder must
have given timely notice thereof in proper written form to the Secretary. To be
timely, a shareholder's notice must be addressed to the Secretary and delivered
to or mailed and received at the principal executive offices of the Corporation
not less than 60 days nor more than 90 days prior to the anniversary date of the
immediately preceding annual meeting; provided, however, that in the event that
                                      --------  -------                        
the date of the annual meeting is more than 30 days earlier or more than 60 days
later than such anniversary date, notice by the shareholder to be timely must be
so delivered or received not earlier than the 90th day prior to such annual
meeting and not later than the close of business on the later of the 60th day
prior to such annual meeting or the 10th day following the day on which public
announcement of the date of such meeting is first made. To be in proper written
form, a shareholder's notice to the Secretary shall set forth in writing as to
each matter the shareholder proposes to bring before the annual meeting: (i) a
brief description of the business desired to be brought before the annual
meeting and the reasons for conducting such business at the annual meeting; (ii)
the name and address, as they appear on the Corporation's books, of the
shareholder proposing such business; (iii) the class and number of shares of the
Corporation which are beneficially owned by the shareholder; (iv) a
representation that the shareholder is or will be entitled to vote at such
annual meeting and intends to appear in person (or send a qualified
representative) or by proxy to present such proposal at the meeting; and (v) any
material interest of the shareholder in such business. The foregoing notice
requirements shall be deemed satisfied by a shareholder if the shareholder has
notified the Corporation of his or her intention to present a proposal at an
annual meeting and such shareholder's proposal has been included in a proxy
statement that has been prepared by management of the Corporation to solicit
proxies for such annual meeting; provided, however, that if such shareholder
                                 --------  -------                          
does not appear in person (or send a qualified representative) or by proxy to
present such proposal at such annual meeting, the Corporation need not present
such proposal for a vote at such meeting, notwithstanding that proxies in
respect of such vote may have been received by the Corporation. Notwithstanding
anything in the By-Laws to the contrary, no business shall be conducted at any
annual meeting except in accordance with the procedures set forth in this
Section 12. The chairman of an annual meeting shall, if the facts warrant,
determine that business was not properly brought before the annual meeting in
accordance with the provisions of this

3/21/83
<PAGE>
 
                                  (6)



Section 12 and, if he should so determine, he shall so declare to the annual
meeting and any such business not properly brought before the annual meeting
shall not be transacted and any proposal contemplated by such business shall be
void.

(a)  Generally.
     ----------

      To the full extent authorized or permitted by law, the Corporation shall
indemnify any person ("indemnified Person") made, or threatened to be made, a
party to any action or proceeding, whether civil, at law, in equity, criminal,
administrative, investigative or otherwise, including any action

by or in the right of the Corporation, by reason of the fact that he, his
testator or intestate, ("Responsible Person"), whether before or after adoption
of this Section 12, (1) is or was a director or officer of the Corporation, or
(2), if a director or officer of the Corporation, is serving or served, in any
capacity, at the request of the Corporation, any other corporation, or any
partnership, joint venture, trust, employee benefit plan or other enterprise, or
(3), if not a director or officer of the Corporation, is serving or served, at
the request of the


3/21/83
*Revised 2/16/87
<PAGE>
 
                                      (11)



Corporation, as a director or officer of any other corporation or any
partnership, joint venture, trust, employee benefit plan or other enterprise,
against all judgments, fines, penalties, amounts paid in settlement (provided
the Corporation shall have given its prior consent to such settlement, which
consent shall not be unreasonably withheld by it) and reasonable expenses,
including attorneys' fees, incurred by such Indemnified Person with respect to
any such threatened or actual action or proceeding, and any appeal therein,
provided only that (x) acts of the Responsible Person which were material to the
cause of action so adjudicated or otherwise disposed of were not (i) committed
in bad faith or (ii) were not the result of active and deliberate dishonesty,
and (y) the Responsible Person did not personally gain in fact a financial
profit or other advantage to which he was not legally entitled.

(b)  Advancement of Expenses.
     ------------------------

      All expenses reasonably incurred by an Indemnified Person in connection
with a threatened or actual action or proceeding with respect to which such
person is or may be entitled to indemnification under this Section 12 shall be
advanced or promptly reimbursed by the Corporation to him in advance of the
final disposition of such action or proceeding, upon receipt of an undertaking
by him or on his behalf to repay the amount of such advances, if any, as to
which he is ultimately found not to be entitled to indemnification or, where
indemnification is granted, to the extent such advances exceed the
indemnification to which he is entitled. Such person shall cooperate in good
faith with any request by the Corporation that common counsel be used by the
parties to an action or proceeding who are similarly situated unless to do so
would be inappropriate due to an actual or potential conflict of interest.

(c)  Procedure for Indemnification.
     ------------------------------

      (1) Not later than thirty (30) days following final disposition of an
action or proceeding with respect to which the Corporation has received written
request by an Indemnified Person for indemnification pursuant to this Section
12, if such indemnification has not been ordered by a court, the Board of
Directors shall meet and find whether the Responsible Person met the standard of
conduct set forth in paragraph (a) of this Section 12, and, if it finds that he
did, or to the extent it so finds, shall authorize such indemnification.


3/21/83
<PAGE>
 
                                      (12)



      (2) Such standard shall be found to have been met unless (a) a judgment or
other final adjudication adverse to the Indemnified Person establishes that
subparagraphs (x) or (y) of paragraph (a) of this Section 12 were violated, or
(b) if the action or proceeding was disposed of other than by judgment or other
final adjudication, the Board finds in good faith that, if it had been disposed
of by judgment or other final adjudication, such judgment or other final
adjudication would have been adverse to the Indemnified Person and would have
established a violation of subparagraphs (x) or (y) of paragraph (a) of this
Section 12.

      (3) If indemnification is denied, in whole or part, because of an adverse
finding by the Board in the absence of a judgment or other final adjudication,
or because the Board believes the expenses for which indemnification is
requested to be unreasonable, such action by the Board shall in no way affect
the right of the Indemnified Person to make application therefor in any court
having jurisdiction thereof, and in such action or proceeding the issue shall be
whether the Responsible Person met the standard of conduct
set forth in paragraph (a) of this Section 12, or whether the expenses were
reasonable, as the case may be (not whether the finding of the Board with
respect thereto was correct) and the determination of such issue shall not be
affected by the Board's finding.  If the judgment or other final adjudication in
such action or proceeding establishes that the Responsible Person met the
standard set forth in paragraph (a) of this Section 12, or that the disallowed
expenses were reasonable, or to the extent that it does, the Board shall then
find such standard to have been met or the expenses to be reasonable, and shall
grant such indemnification, and shall also grant to the Indemnified Person
indemnification of the expenses incurred by him in connection with the action or
proceeding resulting in the judgment or other final adjudication that such
standard of conduct was met, or if pursuant to such court determination such
person is entitled to less than the full amount of indemnification denied by the
Corporation, the portion of such expenses proportionate to the amount of such
indemnification so awarded.

      (4) A finding by the Board pursuant to this paragraph (c) that the
standard of conduct set forth in paragraph (a) of this Section 12 has been met
shall mean a finding of the Board or shareholders as provided by law.

(d)   Contractual Article.
      --------------------

      This Section 12 shall be deemed to constitute a contract between the
Corporation and each person who is a Responsible Person

3/21/83
<PAGE>
 
                                      (13)



at any time while this Section 12 is in effect.  No repeal or amendment of this
Section 12, insofar as it reduces the extent of the indemnification of any
person who could be a Responsible Person shall without his written consent be
effective as to such person with respect to any event, act or omission occurring
or allegedly occurring prior to (1) the date of such repeal or amendment if on
that date he is not serving in any capacity for which he could be a Responsible
Person, or (2) the thirtieth (30th) day following delivery to him of written
notice of such repeal or amendment as to any capacity in which he is serving on
the date of such repeal or amendment, other than as a director or officer of the
Corporation, for which he could be a Responsible Person, or (3) the later of the
