         or, if notice is waived, at the close of business on the day next
         preceding the day on which the meeting is held;

                 2.4.2 The record date for determining Stockholders entitled to

         2.5 NOTICE OF MEETINGS OF STOCKHOLDERS. Except as otherwise provided
in Sections 2.4 and 2.6 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 2.5 has been given 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 


                                      -5-
   9
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.

         2.6 WAIVERS OF NOTICE. Whenever notice is required to be given to any
Stockholder under any provision of the General Corporation Law or 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.

         2.7 LISTS 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 


                                      -6-
   10
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.

         2.8 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
Stockholder or Stockholders. The holders of a 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.

         2.9 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 2.4 of the
By-laws. If the Certificate of Incorporation provides for more or less than one
vote for any share, on any matter, every 


                                      -7-
   11
reference in the Bylaws 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 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 at the commencement of the meeting 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 shall be by voice vote. Every Stockholder entitled to vote
at a meeting of Stockholders may authorize another person or persons to act for


                                      -8-
   12
him by proxy. The validity and enforceability of any proxy shall be determined
in accordance with Section 212 of the General Corporation Law.

         2.10 SELECTION AND DUTIES OF INSPECTORS AT MEETINGS OF STOCKHOLDERS.
The Board in accordance with Section 231 of the General Corporation Law, in
advance of any meeting of Stockholders, shall appoint one or more inspectors to
act at the meeting or any adjournment thereof. In case any person appointed
fails to appear or act, the vacancy shall 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, 


                                      -9-
   13
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.

         2.11 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.

         2.12 ORDER OF BUSINESS. The order of business at all meetings of
Stockholders shall be as determined exclusively by the chairman of the meeting.

                                   DIRECTORS


         3.1 GENERAL POWERS. Except as otherwise provided in the Certificate of
Incorporation, the business and affairs of the Corporation shall be managed by
or under the direction of the Board. The Board may adopt such rules and
regulations, not inconsistent with the Certificate of Incorporation or the
By-laws or applicable laws, as it may deem proper for the conduct of its
meetings and the management of the Corporation. In addition to the powers
expressly conferred by the By-laws, the Board may exercise all powers and
perform all acts which are not required, by the By-laws or the Certificate of
Incorporation or by law, to be exercised and performed by the Stockholders.

         3.2 NOMINATIONS FOR DIRECTORS. Nominations for election to the Board
may be made by the Board or by any holder of shares of any outstanding class of
capital stock of the Corporation entitled to vote for the election of directors.
Nominations other than those made by the Board shall be made by notification in
writing delivered to the Secretary not less than twenty nor more than fifty days
prior to any annual or special meeting of Stockholders called for the election
of directors; provided, however that if less than twenty-eight days notice of
such meeting is given to Stockholders, such nomination shall be delivered to the
Secretary not later than the close of business on the seventh 


                                      -11-

Stockholders.

         3.3 NUMBER; QUALIFICATION; TERM OF OFFICE. The Board shall consist of
not less than one nor more than fifteen members. The total number of directors
shall be fixed initially by the incorporator and may thereafter be changed from
time to time by the Board pursuant to a resolution adopted by a majority of the
Whole Board. Directors need not be Stockholders. Each director shall hold office
until his successor is elected and qualified or until his earlier death,
resignation or removal.

         3.4 ELECTION. Directors shall, except as otherwise required by law or
by the Certificate of Incorporation, be elected by a plurality of the votes cast
at a meeting of Stockholders by the holders of shares entitled to vote in the
election.

         3.5 NEWLY CREATED DIRECTORSHIPS AND VACANCIES. Unless otherwise
provided in the Certificate of Incorporation, newly created directorships
resulting from an increase in the number of directors and vacancies occurring in
the Board for any other reason, including the removal of directors, shall be
filled by vote of a majority of the directors then in office, although less than
a quorum, or by a sole remaining director. A director elected to fill a vacancy
shall be elected to hold office for a term expiring at the annual meeting of
Stockholders at which the term of 


                                      -12-
   16
the class of directors to which he has been elected expires, or until his
earlier death, resignation or removal.

         3.6 RESIGNATIONS. Any director may resign at any time by written
notice to the Corporation. Such resignation shall take effect at the time
therein specified, and, unless otherwise specified, the acceptance of such
resignation shall not be necessary to make it effective.

         3.7 REMOVAL OF DIRECTORS. Any or all of the directors may be removed
from office at any time, with or without cause, but only by the affirmative vote
of the holders of at least two-thirds of the voting power of all of the shares
of the Corporation entitled to vote for the election of directors.

         3.8 COMPENSATION. Each director, in consideration of his service as
such, shall be entitled to receive from the Corporation such amount per annum or
such fees for attendance at directors' meetings, or both, as the Board may from
time to time determine, together with reimbursement for the reasonable expenses
incurred by him in connection with the performance of his duties. Each director
who shall serve as a member of any committee of directors in consideration of
his serving as such shall be entitled to such additional amount per annum or
such fees for attendance at committee meetings, or both, as the Board may from
time to time determine, together with reimbursement for the reasonable expenses
incurred by him in the performance of his duties. Nothing contained in this
section shall preclude any 


                                      -13-
   17
director from serving the Corporation or its subsidiaries in any other capacity
and receiving proper compensation therefor.

         3.9 PLACE AND TIME OF MEETINGS OF THE BOARD. Meetings of the Board,
regular or special, may be held at any place within or without the State of
Delaware. The times and places for holding meetings of the Board may be fixed
from time to time by resolution of the Board or (unless contrary to resolution
of the Board) in the notice of the meeting.

         3.10 ANNUAL MEETINGS. On the day when and at the place where the
annual meeting of Stockholders for the election of directors is held, and as
soon as practicable thereafter, the Board may hold its annual meeting, without

registration of transfer of capital stock of the Corporation may be imposed

         discretion, it may think proper, as a reserve fund to meet
         contingencies, or for equalizing dividends or for the purpose of
         maintaining or increasing the property or business of the Corporation,
         or for any purpose it may think conducive to the best interests of the
