     Section 2.3. Special Meetings.  Special meetings of the stockholders, for
                  ----------------                                            
any purpose or purposes, unless otherwise prescribed by statute or by the
Certificate of Incorporation, may be called at any time by the Chairman of the
Board, the President or shall be called by the President or Secretary at the
request in writing of a majority of the Board of Directors, or at the request in
writing of stockholders holding a majority of the entire capital stock of the
Corporation issued and outstanding and entitled to vote.  Such request shall
state the purpose or purposes of the proposed meeting.  Business transacted at
any special meeting of stockholders shall be limited to the purposes stated in
the notice.

     Section 2.4. Notice of Meetings.  Whenever stockholders are required or
                  ------------------                                        
permitted to take 

 
any action at a meeting, a written notice of the meeting stating the place, date
and hour of the meeting, and, in the case of a special meeting, the purpose of

                  --------------------                                        
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.

     Section 2.6. Quorum.  At each meeting of stockholders the presence in
                  ------                                                  
person or by proxy of the holders of shares of stock having a majority of the
votes which could be cast by the holders of all outstanding shares of stock
entitled to vote at the meeting, shall be necessary and sufficient to constitute
a quorum for the transaction of business except as otherwise provided by
statute, by the Certificate of Incorporation or by these By-laws.  In the
absence of a quorum, the stockholders so present may, by majority vote, adjourn
the meeting from time to time, without notice other than announcement at the
meeting, until a quorum shall be present or represented.  At any such adjourned
meeting at which a quorum shall be present or represented, any business may be
transacted which might have been transacted at the original meeting as
originally notified.  If 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.  Shares of its own stock belonging to the
Corporation or to another corporation, if a majority of the shares entitled to
vote in the election of directors of such other corporation is held, directly or
indirectly, by the Corporation, shall neither be entitled to vote nor be counted
for quorum purposes; provided, however, that the foregoing shall not limit the
                     --------  -------                                        
right of the Corporation to vote stock, including, but not limited, to its own
stock, held by it in a fiduciary capacity.

     Section 2.7. Organization.  Meetings of stockholders shall be presided over
                  ------------                                                  
by the Chairman of the Board, if any, or in his or her absence, by the Vice
Chairman of the Board, if any, or in his or her absence by the President, or in
his or her absence by a Vice President, or in the absence of the foregoing
persons by a chairman designated by the Board of Directors.  The Secretary shall
act as secretary of the meeting, but in his or her absence the chairman of the
meeting may appoint any person to act as secretary of the meeting.

     Section 2.8. Voting: Proxies.  Except as otherwise provided by the
                  ---------------                                      
Certificate of Incorporation, each stockholder entitled to vote at any meeting
of stockholders shall be entitled to one vote for each share of stock held by
such stockholder which has voting power upon the matter in question.  Each
stockholder entitled to vote at a meeting of stockholders may authorize another
person or persons to act for such stockholder by proxy, but no such proxy shall
be voted or acted upon after three years from its date, unless the proxy
provides for a longer period.  A duly executed proxy shall be irrevocable if it
states that it is irrevocable and if, and only as long as, it is coupled with an
interest sufficient in law to support an irrevocable power.  A stockholder may
revoke any proxy which is not irrevocable by attending the meeting and voting in
person or by filing an instrument in writing revoking the proxy or 

 
another duly executed proxy bearing a later date with the Secretary of the
Corporation. Voting at meetings of stockholders need not be by written ballot
and need not be conducted by inspectors of election unless so determined by the
holders of shares of stock having a majority of the votes which could be cast by
the holders of all outstanding shares of stock entitled to vote thereon which
are present in person or by proxy at such meeting. At all meetings of
stockholders for the election of directors a plurality of the votes cast shall
be sufficient to elect. All other elections and questions shall, unless
otherwise provided by law, the Certificate of Incorporation or these By-laws, be
decided by the vote of the holders of shares of stock having a majority of the
votes which could be cast by the holders of all shares of stock entitled to vote
thereon which are present in person or represented by proxy at the meeting.

     Section 2.9. Action without Meeting. Unless otherwise restricted by the
                  ----------------------                                    
Certificate of Incorporation, any action required or permitted to be taken at
any annual or special meeting of 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.

     Section 2.10.  Fixing Date for Determination of Stockholders of Record.  In
                    -------------------------------------------------------     
order that the Corporation may determine the stockholders entitled to notice of
or to vote at any meeting of stockholders or any adjournment thereof, or to
express consent to corporate action in writing without a meeting, or to receive
payment of any dividend or other distribution or allotment of any rights, or to
exercise any rights in respect of any change, conversion or exchange of stock or
for the purpose of any other lawful action, the Board of Directors may fix a
record date, which record date shall not precede the date upon which the
resolution fixing the record date is adopted by the Board of Directors and which
record date: (1) in the case of determination of stockholders entitled to vote
at any meeting of stockholders or adjournment thereof, shall, unless otherwise
required by law, not be more than sixty nor less than ten days before the date
of such meeting; (2) in the case of determination of stockholders entitled to
express consent to corporate action in writing without a meeting, shall not be
more than ten days from the date upon which the resolution fixing the record
date is adopted by the Board of Directors; and (3) in the case of any other
action, shall not be more than sixty days prior to such other action.  If no
record date is fixed: (1) the record date for determining stockholders entitled
to notice of or to vote at a meeting of stockholders shall be at the close of
business on the day next preceding the day on which notice is given, or, if
notice is waived, at the close of business on the day next preceding the day on
which the meeting is held; (2) the record date for determining stockholders
entitled to express consent to corporate action in writing without a meeting
when no prior action of the Board of Directors is required by law, shall be the
first date on which a signed written consent setting forth the action taken or
proposed to be taken is delivered to the Corporation in accordance with
applicable law, or, if prior action by the Board of Directors is required by
law, shall be at the close of business on the day on which the Board of
Directors adopts the resolution taking such prior action; and (3) the record
date for determining stockholders for any other purpose shall be at the close of
business on the day on which the Board of Directors adopts the resolution
relating thereto.  A determination of stockholders of record entitled to notice
of or to vote at a meeting of stockholders shall apply to any adjournment of the
meeting; provided, however, that the Board of Directors may fix a new record
         --------  -------                                                  
date for the adjourned meeting.

 
                                  ARTICLE III

                              Board of Directors


     Section 3.1. Number; Qualifications.  The Board of Directors shall consist
                  ----------------------                                       
of not less than five nor more than eleven members, as shall be determined from
time to time by resolution of the Board of Directors, subject to the power of
the stockholders to change such action.  At least three of the directors shall
be "Independent Directors".  For purposes of these By-laws "Independent
Director" shall mean a person, other than an officer or employee of the
Corporation or its subsidiaries or any other individual who has a relationship
with the Corporation which, in the opinion of the Board of Directors, would
interfere with the exercise of independent judgment in carrying out the
responsibilities of a director.  The directors need not be stockholders.

          Section 3.2.  Election and Terms of Directors; Board Action.   The
                        ---------------------------------------------       
directors, other than those who may be elected pursuant to the Certificate of
Incorporation by the holders of any series of preferred stock voting separately
as a single class, shall be divided, with respect to the time for which they
severally hold office, into three classes with the initial term of office of the
first class to expire at the 1997 annual meeting of stockholders, the initial
term of office of the second class to expire at the 1998 annual meeting of
stockholders and the initial term of office of the third class to expire at the
1999 annual meeting of stockholders, with each such director to hold office
until his or her successor shall have been duly elected and qualified.  At each
annual meeting of stockholders, commencing with the 1997 annual meeting of
stockholders, (i) directors elected to succeed those directors whose terms then
expire shall be elected for a term of office to expire at the third succeeding
annual meeting of stockholders after their election and until his or her
successor shall have been duly elected and qualified, and (ii) if authorized by
a resolution of the Board of Directors and except as otherwise provided in the
Certificate of Incorporation with respect to the rights of the holders of any
series of preferred stock to elect directors, directors may be elected to fill
any vacancy on the Board of Directors, regardless of how such vacancy shall have
been created.  Any director who may be elected pursuant to the Certificate of
Incorporation by the holders of any series of preferred stock voting separately
as a single class, shall, at each annual meeting of stockholders, be elected for
a term of office to expire at the next annual meeting of stockholders and until
his or her successor shall have been duly elected and qualified or until such
director resigns or is removed from office by the holders of such series of
preferred stock; provided, however, that the term of office of any such director
                 --------  -------                                              
shall expire at the next annual meeting that follows the date as of which any
such preferred stock shall no longer be outstanding.

          Section 3.3.  Newly Created Directorships and Vacancies; Resignation;
                        -------------------------------------------------------
Removal.  Subject to applicable law and to the rights of the holders of any
- -------                                                                    
series of preferred stock to elect directors as provided in the Certificate of
Incorporation, and unless the Board of Directors otherwise determines, newly
created directorships resulting from any increase in the authorized number of
directors or any vacancies on the Board of Directors resulting from death,
resignation, retirement, disqualification, removal from office or other cause
shall be filled only by a majority vote of the directors then in office, though
less than a quorum, and directors so chosen shall hold office for a term
expiring at the annual meeting of stockholders at which the term of office of
the class to which they have been elected expires and until such director's
successor shall have been duly elected and qualified.  If there are no directors
in office, subject to the rights of the holders of any series of preferred stock
to elect directors as provided in the Certificate of Incorporation, then an
election of directors may be held in the manner provided by statute.  If, at the
time of filling any newly created directorship or any vacancy, the directors
then in office shall constitute less than a majority of the whole Board (as
constituted immediately prior to any such increase), the Court of Chancery may,
upon application of any stockholder or stockholders holding 

 
at least ten percent of the total number of shares at the time outstanding
having the right to vote for such directors, summarily order an election to fill
any such newly created directorships or vacancies, or to replace the directors
chosen by the directors then in office. No decrease in the number of authorized
directors constituting the entire Board of Directors shall shorten the term of
any incumbent director. If a director elected by the holders of any series of
preferred stock entitled to vote separately as a single class is removed by such
holders, and if the holders of such series of preferred stock for any reason
fail to elect anyone to fill any such directorship, such position shall remain
vacant until such time as the holders of such series of preferred stock elect a
director to fill such position and shall not be filled by resolution or vote of
the Corporation's Board of Directors or the Corporation's other stockholders.
Any director may resign at any time upon written notice to the Corporation. Any
director classified pursuant to Section 3.2, or all such directors, may be
removed from office at any time, but only for cause and only by the affirmative
vote of the holders of at least 75 percent of the voting power of all of the
then outstanding shares entitled to vote generally in the election of directors,
voting together as a single class. Any director who may be elected pursuant to
the Certificate of Incorporation by the holders of any series of preferred stock
voting separately as a single class may be removed from office at any time, with
or without cause, by the affirmative vote of the holders of a majority of the
shares of such series of preferred stock voting separately as a single class.

     Section 3.4. Powers.  The business of the Corporation shall be managed by
                  ------

stockholders at which such directors are elected and no notice of such meeting
shall be necessary to the newly elected directors in order legally to constitute
the meeting.

                  ----------------

State of Delaware as shall from time to time be determined by the Board.

notice to each director, either personally or by mail, by telegram, facsimile or

like manner and on like notice on the written request of two directors.

     Section 3.9. Quorum.  At all meetings of the Board of Directors a majority
                  ------                                                       
of the total number of directors shall constitute a quorum for the transaction
of business and the act of a majority of the directors present at any meeting at
which there is a quorum shall be the act of the Board of Directors, except as
may be otherwise specifically provided by statute or by the Certificate of
Incorporation.  If a quorum shall not be present at any meeting of the Board of
Directors the directors present thereat may adjourn the meeting from time to
time, without notice other than announcement at the meeting, until a quorum
shall be present.

     Section 3.10. Conference Telephone.  Members of the Board of Directors (or
                   --------------------                                        
any committee designated by the Board) may participate in a meeting of the Board
or committee thereof by means of 

 
conference telephone or similar communications equipment by means of which all
persons participating in the meeting can hear each other. Participation in a

may be taken without a meeting, if all members of the Board or committee, as the
case may be, consent thereto in writing, and the writing or writings are filed
with the minutes of proceedings of the Board or committee.

     Section 3.13. Committees.  The Board of Directors may, by resolution passed
                   ----------                                                   
by a majority of the whole Board, designate one or more committees, each
committee to consist of two or more of the directors of the Corporation.  The
Board of Directors may designate one or more directors as alternate members of

committee or committees, the member or members thereof present at any meeting

Directors to act at the meeting in the place of any such absent or disqualified
