     1.1  Place of Meetings.  All meetings of stockholders shall be held at such
          -----------------
place within or without the State of Delaware as may be designated from time to
time by the Board of Directors or the President or, if not so designated, at the

     1.2  Annual Meeting.     The annual meeting of stockholders for the
          --------------
election of directors and for the transaction of such other business as may
properly be brought before the meeting shall be held on a date to be fixed by
the Board of Directors or the President (which date shall not be a legal holiday
in the place where the meeting is to be held) at the time and place to be fixed
by the Board of Directors or the President and stated in the notice of the
meeting. If no annual meeting is held in accordance with the foregoing
provisions, the Board of Directors shall cause the meeting to be held as soon
thereafter as convenient. If no annual meeting is held in accordance with the
foregoing provisions, a special meeting may be held in lieu of the annual
meeting, and any action taken at that special meeting shall have the same effect
as if it had been taken at the annual meeting, and in such case all references
in these By-laws to the annual meeting of the stockholders shall be deemed to
refer to such special meeting.

     1.3  Special Meetings.   Special meetings of stockholders may be called at
          ----------------
any time by the President or by the Board of Directors.  Business transacted at
any special meeting of stockholders shall be limited to matters relating to the
purpose or purposes stated in the notice of meeting.

     1.4  Notice of Meetings. Except as otherwise provided by law, written
          ------------------
notice of each meeting of stockholders, whether annual or special, shall be
given not less than 10 nor more than 60 days before the date of the meeting to
each stockholder entitled to vote at such meeting.  The notices of all meetings
shall state the place, date and hour of the meeting.  The notice of a special
meeting shall state, in addition, the purpose or purposes for which the meeting
is called.  If mailed, notice is given when deposited in the United States mail,
postage prepaid, directed to the stockholder at his address as it appears on the
records of the corporation.

                                      -1-

     1.5  Voting List.  The officer who has charge of the stock ledger of the
          -----------
corporation shall prepare, at least 10 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
10 days prior to the meeting, at a place within the city 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 of the meeting, and may be inspected by any
stockholder who is present.

     1.6  Quorum.  Except as otherwise provided by law, the Certificate of
          ------
Incorporation or these By-laws, the holders of a majority of the shares of the
capital stock of the corporation issued and outstanding and entitled to vote at
the meeting, present in person or represented by proxy, shall constitute a
quorum for the transaction of business.

     1.7  Adjournments.  Any meeting of stockholders may be adjourned to any
          ------------
other time and to any other place at which a meeting of stockholders may be held
under these By-laws by the stockholders present or represented at the meeting
and entitled to vote, although less than a quorum, or, if no stockholder is
present, by any officer entitled to preside at or to act as Secretary of such
meeting.  It shall not be necessary to notify any stockholder of any adjournment
of less than 30 days if the time and place of the adjourned meeting are
announced at the meeting at which adjournment is taken, unless after the
adjournment a new record date is fixed for the adjourned meeting.  At the
adjourned meeting, the corporation may transact any business which might have
been transacted at the original meeting.

     1.8  Voting and Proxies.  Each stockholder shall have one vote for each
          ------------------
share of stock entitled to vote held of record by such stockholder and a
proportionate vote for each fractional share so held, unless otherwise provided
in the Certificate of Incorporation.  Each stockholder of record entitled to
vote at a meeting of stockholders, or to express consent or dissent to corporate
action in writing without a meeting, may vote or express such consent or dissent
in person or may authorize another person or persons to vote or act for him by
written proxy executed by the stockholder or his authorized agent and delivered
to the Secretary of the corporation. No such proxy shall be voted or acted upon
after three years from the date of its execution, unless the proxy expressly
provides for a longer period.

     1.9  Action at Meeting.  When a quorum is present at any meeting, the
          -----------------
holders of shares of stock representing a majority of the votes cast on a matter
(or if there are two or more classes of stock entitled to vote as separate
classes, then in the case of each such class, the holders of shares of stock of
that class representing a

                                      -2-
<PAGE>

majority of the votes cast on a matter) shall decide any matter to be voted upon
by the stockholders at such meeting, except when a different vote is required by
express provision of law, the Certificate of Incorporation or these By-Laws.
When a quorum is present at any meeting, any election by stockholders shall be
determined by a plurality of the votes cast on the election.

     1.10 Action without Meeting.  Any action required or permitted to be taken
          ----------------------
at any annual or special meeting of stockholders of the corporation may be taken
without a meeting, without prior notice and without a vote, if a consent in
writing, setting forth the action so taken, is 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 on such action were present and voted.  Prompt notice of the
taking of corporate action without a meeting by less than unanimous written
consent shall be given to those stockholders who have not consented in writing.


                            ARTICLE 2  - Directors
                            ----------------------


     2.1  General Powers.  The business and affairs of the corporation shall be
          --------------
managed by or under the direction of a Board of Directors, who may exercise all
of the powers of the corporation except as otherwise provided by law or the
Certificate of Incorporation.  In the event of a vacancy in the Board of
Directors, the remaining directors, except as otherwise provided by law, may
exercise the powers of the full Board until the vacancy is filled.

     2.2  Number; Election and Qualification.  The number of directors which
          ----------------------------------
shall constitute the whole Board of Directors shall be determined by resolution
of the stockholders or the Board of Directors, but in no event shall be less
than one.  The number of directors may be decreased at any time and from time to
time either by the stockholders or by a majority of the directors then in
office, but only to eliminate vacancies existing by reason of the death,
resignation, removal or expiration of the term of one or more directors.  The
directors shall be elected at the annual meeting of stockholders by such
stockholders as have the right to vote on such election. Directors need not be
stockholders of the corporation.

     2.3  Enlargement of the Board.  The number of directors may be increased at
          ------------------------
any time and from time to time by the stockholders or by a majority of the
directors then in office.

          ------
and until his successor is elected and qualified, or until his earlier death,
resignation or removal.

                                      -3-
<PAGE>

     2.5  Vacancies.  Unless and until filled by the stockholders, any vacancy
          ---------
in the Board of Directors, however occurring, including a vacancy resulting from
an enlargement of the Board, may 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 for the
unexpired term of his predecessor in office, and a director chosen to fill a
position resulting from an increase in the number of directors shall hold office
until the next annual meeting of stockholders and until his successor is elected
and qualified, or until his earlier death, resignation or removal.

     2.6  Resignation.  Any director may resign by delivering his written
          -----------
resignation to the corporation at its principal office or to the President or
Secretary. Such resignation shall be effective upon receipt unless it is
specified to be effective at some other time or upon the happening of some other
event.

     2.7  Regular Meetings.  Regular meetings of the Board of Directors may be
          ----------------
held without notice at such time and place, either within or without the State
of Delaware, as shall be determined from time to time by the Board of Directors;
provided that any director who is absent when such a determination is made shall
be given notice of the determination.  A regular meeting of the Board of
Directors may be held without notice immediately after and at the same place as
the annual meeting of stockholders.

     2.8  Special Meetings.  Special meetings of the Board of Directors may be
          ----------------
held at any time and place, within or without the State of Delaware, designated
in a call by the Chairman of the Board, President, two or more directors, or by
one director in the event that there is only a single director in office.

     2.9  Notice of Special Meetings.  Notice of any special meeting of
          --------------------------
directors shall be given to each director by the Secretary or by the officer or
one of the directors calling the meeting.  Notice shall be duly given to each
director (i) by giving notice to such director in person or by telephone at
least 48 hours in advance of the meeting, (ii) by sending a telegram or telex,
or delivering written notice by hand, to his last known business or home address
at least 48 hours in advance of the meeting, or (iii) by mailing written notice
to his last known business or home address at least 72 hours in advance of the
meeting.  A notice or waiver of notice of a meeting of the Board of Directors
need not specify the purposes of the meeting.

     2.10 Meetings by Telephone Conference Calls.  Directors or any members of
          --------------------------------------
any committee designated by the directors may participate in a meeting of the
Board of Directors or such committee by means of conference telephone or similar
communications equipment by means of which all persons participating in the

                                      -4-
<PAGE>

meeting can hear each other, and participation by such means shall constitute
presence in person at such meeting.

     2.11 Quorum.  A majority of the total number of the whole Board of
          ------
Directors shall constitute a quorum at all meetings of the Board of Directors.
In the event one or more of the directors shall be disqualified to vote at any
meeting, then the required quorum shall be reduced by one for each such director
so disqualified; provided, however, that in no case shall less than one-third
(1/3) of the number so fixed constitute a quorum.  In the absence of a quorum at
any such meeting, a majority of the directors present may adjourn the meeting
from time to time without further notice other than announcement at the meeting,
until a quorum shall be present.

     2.12 Action at Meeting.  At any meeting of the Board of Directors at which
          -----------------
a quorum is present, the vote of a majority of those present shall be sufficient
to take any action, unless a different vote is specified by law, the Certificate
of Incorporation or these By-Laws.

     2.13 Action by Consent.  Any action required or permitted to be taken at
          -----------------
any meeting of the Board of Directors or of any committee of the Board of
Directors may be taken without a meeting, if all members of the Board or
committee, as the case may be, consent to the action in writing, and the written
consents are filed with the minutes of proceedings of the Board or committee.

     2.14 Removal.  Except as otherwise provided by the General Corporation Law
          -------
of Delaware, any one or more or all of the directors may be removed, with or
without cause, by the holders of a majority of the shares then entitled to vote
at an election of directors, except that the directors elected by the holders of
a particular class or series of stock may be removed without cause only by vote
of the holders of a majority of the outstanding shares of such class or series.

     2.15 Committees.  The Board of Directors may designate one or more
          ----------
committees, each committee to consist of one or more of the directors of the
corporation.  The Board may designate one or more directors as alternate members
of any committee, who may replace any absent or disqualified member at any
meeting of the committee.  In the absence or disqualification of a member of a
committee, the member or members of the committee present at any meeting and not
disqualified from voting, whether or not he or they constitute a quorum, may
unanimously appoint another member of the Board of Directors to act at the
meeting in the place of any such absent or disqualified member.  Any such
committee, to the extent provided in the resolution of the Board of Directors
and subject to the provisions of the General Corporation Law of the State of
Delaware, shall have and may exercise all the powers and authority of the Board
of Directors in the management of the business and affairs of the corporation
and may authorize the seal of the corporation

                                      -5-
<PAGE>

to be affixed to all papers which may require it. Each such committee shall keep
minutes and make such reports as the Board of Directors may from time to time
request. Except as the Board of Directors may otherwise determine, any committee
may make rules for the conduct of its business, but unless otherwise provided by
the directors or in such rules, its business shall be conducted as nearly as
possible in the same manner as is provided in these By-laws for the Board of
Directors.

     2.16 Compensation of Directors.  Directors may be paid such compensation
          -------------------------
for their services and such reimbursement for expenses of attendance at meetings
as the Board of Directors may from time to time determine.  No such payment
shall preclude any director from serving the corporation or any of its parent or
subsidiary corporations in any other capacity and receiving compensation for
such service.
