             2.6  Notice of Meetings of Stockholders. Except as otherwise
                  ----------------------------------
provided in Sections 2.5 and 2.7 of the By-laws, whenever under the General
Corporation Law or the Certificate of Incorporation or the By-laws, stockholders
are required or permitted to take any action at a meeting, written notice shall
be given stating 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. A copy
of the notice of any meeting shall be given, personally or by mail, not less
than ten nor more than sixty days before the date of the meeting, to each
stockholder entitled to notice of or to vote at such meeting. If mailed, such
notice shall be deemed to be given when deposited in the United States mail,
with postage prepaid, directed to the stockholder at his address as it appears
on the records of the Corporation. An affidavit of the Secretary or an Assistant
Secretary or of the transfer agent of the Corporation that the notice required
by this section has been given 

                                       5

 
shall, in the absence of fraud, be prima facie evidence of the facts stated
therein. When a meeting is adjourned to another time or place, notice need not
be given of the adjourned meeting if the time and place thereof are announced at
the meeting at which the adjournment is taken, and at the adjourned meeting any
business may be transacted that might have been transacted at the meeting as
originally called. If, however, 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 stockholder of record
entitled to vote at the meeting.

             2.7  Waivers of Notice. Whenever notice is required to be given to 
                  -----------------
any stockholder under any provision of the General Corporation Law or of the
Certificate of Incorporation or the By-laws, a written waiver thereof, signed by
the stockholder entitled to notice, whether before or after the time stated
therein, shall be deemed equivalent to notice. Attendance of a stockholder at a
meeting shall constitute a waiver of notice of such meeting, except when the
stockholder 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 stockholders need be
specified in any written waiver of notice.

                                       6

 
             2.8  List of Stockholders. The Secretary shall prepare and make, or
                  --------------------
cause to be prepared and made, at least ten days before every meeting of
stockholders, a complete list of the stockholders entitled to vote at the
meeting, arranged in alphabetical order, and showing the address of each
stockholder and the number of shares registered in the name of each stockholder.
Such list shall be open to the examination of any stockholder, 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 stockholder who is
present.

             2.9  Quorum of Stockholders; Adjournment. The holders of one-third
                  -----------------------------------
of the shares of stock entitled to vote at any meeting of stockholders, present
in person or represented by proxy, shall constitute a quorum for the transaction
of any business at such meeting. When a quorum is once present to organize a
meeting of stockholders, it is not broken by the subsequent withdrawal of any
stockholders. The holders of a

                                       7

 
majority of the shares of stock present in person or represented by proxy at any
meeting of stockholders, including an adjourned meeting, whether or not a quorum
is present, may adjourn such meeting to another time and place.

             2.10 Voting; Proxies. Unless otherwise provided in the Certificate
                  ---------------
of Incorporation every stockholder of record shall be entitled at every meeting
of stockholders to one vote for each share of capital stock standing in his name
on the record of stockholders determined in accordance with Section 2.5 of the
By-laws. If the Certificate of Incorporation provides for more or less than one
vote for any share, on any matter, every reference in the By-laws or the General
Corporation Law to a majority or other proportion of stock shall refer to such
majority or other proportion of the votes of such stock. The provisions of
Sections 212 and 217 of the General Corporation Law shall apply in determining
whether any shares of capital stock may be voted and the persons, if any,
entitled to vote such shares; but the Corporation shall be protected in treating
the persons in whose names shares of capital stock stand on the record of
stockholders as owners thereof for all purposes. At any meeting of stockholders
(at which a quorum was present to organize the meeting), all matters, except as
otherwise provided by law or by the Certificate of Incorporation or by the By-
laws, shall be decided by a majority of the votes 

                                       8

 
cast at such meeting by the holders of shares present in person or represented
by proxy and entitled to vote thereon, whether or not a quorum is present when
the vote is taken. All elections of directors shall be by written ballot unless
otherwise provided in the Certificate of Incorporation. In voting on any other
question on which a vote by ballot is required by law or is demanded by any
stockholder entitled to vote, the voting shall be by ballot. Each ballot shall
be signed by the stockholder voting or by his proxy, and shall state the number
of shares voted. On all other questions, the voting may be viva voce. Every
                                                           ---- ----  
stockholder entitled to vote at a meeting of stockholders or to express consent
or dissent without a meeting may authorize another person or persons to act for
him by proxy. The validity and enforceability of any proxy shall be determined
in accordance with Section 212 of the General Corporation Law. 


             2.11 Selection and Duties of Inspectors at Meetings of
                  -------------------------------------------------
Stockholders. The Board, in advance of any meeting of stockholders, may appoint
- ------------
one or more inspectors to act at the meeting or any adjournment thereof. If
inspectors are not so appointed, the person presiding at such meeting may, and
on the request of any stockholder entitled to vote thereat shall, appoint one or
more inspectors. In case any person 

                                       9

 
appointed fails to appear or act, the vacancy may be filled by appointment made
by the Board in advance of the meeting or at the meeting by the person presiding
thereat. Each inspector, before entering upon the discharge of his duties, shall
take and sign an oath faithfully to execute the duties of inspector at such
meeting with strict impartiality and according to the best of his ability. The
inspector or inspectors shall determine the number of shares outstanding and the
voting power of each, the shares represented at the meeting, the existence of a
quorum, the validity and effect of proxies, and shall receive votes, ballots or
consents, hear and determine all challenges and questions arising in connection
with the right to vote, count and tabulate all votes, ballots or consents,
determine the result, and do such acts as are proper to conduct the election or
vote with fairness to all stockholders. On request of the person presiding at
the meeting or any stockholder entitled to vote thereat, the inspector or
inspectors shall make a report in writing of any challenge, question or matter
determined by him or them and execute a certificate of any fact found by him or
them. Any report or certificate made by the inspector or inspectors shall be
prima facie evidence of the facts stated and of the vote as certified by him or
them.

             2.12 Organization. At every meeting of stockholders, the President,
                  ------------
or in the absence of the President a Vice President, and in case more than one
Vice President shall be present, that Vice President designated by the Board (or
in the absence of any such designation, the most senior Vice President, based on
age, present), shall act as chairman of the meeting. The Secretary, or in his
absence one of the Assistant Secretaries, shall act as secretary of the meeting.
In case none of the officers above designated to act as chairman or secretary of
the meeting, respectively, shall be present, a chairman or a secretary of the
meeting, as the case may be, shall be chosen by a majority of the votes cast at
such meeting by the holders of shares of capital stock present in person or
represented by proxy and entitled to vote at the meeting.

             2.13 Order of Business. The order of business at all meetings of
                  -----------------
stockholders shall be as determined by the chairman of the meeting, but the
order of business to be followed at any meeting at which a quorum is present may
be changed by a majority of the votes cast at such meeting by the holders of
shares of capital stock present in person or represented by proxy and entitled
to vote at the meeting.
      
             2.14 Written Consent of Stockholders Without a Meeting. Unless
                  -------------------------------------------------
otherwise provided in the Certificate of Incor-

                                       11

 
poration, any action required by the General Corporation Law to be taken at any
annual or special meeting of stockholders of the Corporation, or any action
which may be taken at any annual or special meeting of such stockholders, may be
taken without a meeting, without prior notice and without a vote, if a consent
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. Prompt notice of the taking of
the corporate action without a meeting by less than unanimous written consent
shall be given to those stockholders who have not consented in writing.
