shall be held for the election of directors at such date, time and place, either
within or without the State of Delaware, as may be designated by resolution of
the Board of Directors from time to time.  Any other proper business may be
transacted at the annual meeting.

          Section 1.2.  Special Meetings.  Special meetings of stockholders for
                        ----------------                                       
any purpose or purposes may be called at any time by the Board of Directors, or
by a committee of the Board of Directors that has been duly designated by the
Board of Directors and whose powers and authority, as expressly provided in a
resolution of the Board of Directors, include the power to call such meetings,
but such special meetings may not be called by any other person or persons.

          Section 1.3.  Notice of Meetings.  Whenever stockholders are required
                        -------------------                                    
or permitted to take any  action at a meeting, a written notice of the meeting
shall be given that shall state 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.  Unless otherwise provided by law, the certificate of incorporation or
these by-laws, the written notice of any meeting shall be given not less than
ten (10) nor more than sixty (60) days before the date of the meeting to each
stockholder entitled to vote at such meeting.  If mailed, such notice shall be
deemed to be 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.

          Section 1.4.  Adjournments.  Any meeting of stockholders, annual or
                        ------------                                         
special, may adjourn from time to time to reconvene at the same or some other
place, and notice need not be given of any such adjourned meeting if the time
and place thereof are announced at the meeting at which the adjournment is
taken.  At the adjourned meeting the corporation may transact any business which
might have been transacted at the original meeting.  If the adjournment is for
more than thirty (30) days, or if after the adjournment a new record date is
fixed for the adjourned meeting, notice of the adjourned meeting shall be given
to each stockholder of record entitled to vote at the meeting.

          Section 1.5.  Quorum.  Except as otherwise provided by law, the
                        -------                                          
certificate of incorporation or these by-laws, at each meeting of stockholders
the presence in person or by proxy of the holders of a majority in voting power
of the outstanding shares of stock entitled to 

 
vote at the meeting shall be necessary and sufficient to constitute a quorum. In
the absence of a quorum, the stockholders so present may, by majority vote,
adjourn the meeting from time to time in the manner provided in Section 1.4 of
these by-laws until a quorum shall attend. 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 or any subsidiary of the corporation to vote
stock, including but not limited to its own stock, held by it in a fiduciary
capacity.

          Section 1.6.  Organization.  Meetings of stockholders shall be
                        ------------                                    
presided over by the Chairman of the Board, if any, or in his absence by the
Vice Chairman of the Board, if any, or in his absence by the President, or in
his absence by a Vice President, or in the absence of the foregoing persons by a
chairman designated by the Board of Directors, or in the absence of such
designation by a chairman chosen at the meeting.  The Secretary shall act as
secretary of the meeting, but in his absence the person presiding over the
meeting may appoint any person to act as secretary of the meeting.  The person
presiding over the meeting shall announce at the meeting of stockholders the
date and time of the opening and the closing of the polls for each matter upon
which the stockholders will vote.

          Section 1.7.  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 (1) vote for each share of stock held
by him which has voting power upon the matter in question.  Each stockholder
entitled to vote at a meeting of stockholders or to express consent or dissent
to corporate action in writing without a meeting may authorize another person or
persons to act for him by proxy, but no such proxy shall be voted or acted upon
after three (3) years from its date, unless the proxy provides for a longer
period.  A 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 with the
Secretary of the corporation an instrument in writing revoking the proxy or by
delivering a proxy in accordance with applicable law bearing a later date to the
Secretary of the corporation.  Voting at meetings of stockholders need not be by
written ballot. At all meeting 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 affirmative vote of the
holders of a majority in voting power of the shares of stock which are present
in person or by proxy and entitled to vote thereon.

          Section 1.8.  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 entitled to
receive payment of any dividend or other distribution or allotment of any
rights, or entitled to exercise any rights in respect to 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 

                                       2

 
record date is adopted by the Board of Directors, and which record date: (i) 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 (60) nor less than ten (10) days before the date of such
meeting; (ii) 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 (10) days from the date upon which the resolution fixing the record date is
adopted by the Board of Directors; and (iii) in the case of determination of
stockholders for the purpose of any other lawful action, shall not be more than
sixty (60) days prior to such other action. If no record date is fixed: (iv) 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; (v) 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 (vi) the record date for determining stockholders for the
purpose of any other lawful action, shall be at the close of business on the day
on which the Board of Director 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.

          Section 1.9.  List of Stockholders Entitled to Vote.  The Secretary
                        -------------------------------------                
shall prepare and make, at least ten (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
ten (10) 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.  Upon the willful neglect or refusal of the directors to produce such a
list at any meeting for the election of directors, they shall be ineligible for
election to any office at such meeting.  Except as otherwise provided by law,
the stock ledger shall be the only evidence as to who are the stockholders
entitled (i) to examine the stock ledger, the list of stockholders entitled to
vote at the meeting or the books of the corporation, (ii)  to vote in person or
by proxy at any meeting of stockholders, or (iii) to express consent or dissent
to corporate action in writing without a meeting.

          Section 1.10.  Action By Consent of Stockholders.  Unless otherwise
                         ---------------------------------                   
restricted by the certificate of incorporation, any action required or permitted
to be taken at any annual or special meeting of the stockholders may be taken
without a meeting, without prior notice and without a vote, if a consent or
consents in writing, setting forth the action so taken, shall be signed by the

                                       3

 
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 and shall be
delivered (by hand or by certified or registered mail, return receipt requested)
to the corporation by delivery to its registered office in the State of
Delaware, its principal place of business, or an officer or agent of the
corporation having custody of the book in which minutes of proceedings of
meetings of stockholders are recorded.  Prompt notice of taking 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 1.11.  Inspectors of Election.  The corporation may, and shall
                         ----------------------                                 
if required by law, in advance of any meeting of stockholders, appoint one (1)
or more inspectors of election, who may be employees of the corporation, to act
at the meeting or any adjournment thereof and to make a written report thereof.
The corporation may designate one (1) or more persons as alternate inspectors to
replace any inspector who fails to act.  In the event that no inspector so
appointed or designated is able to act at a meeting of the stockholders, the
person presiding at the meeting shall appoint one (1) or more inspectors to act
at the meeting.  Each inspector, before entering upon the discharge of his or
her duties, shall take and sign an oath to execute faithfully the duties of
inspector with strict impartiality and according to the best of his or her
ability.  The inspector or inspectors so appointed or designated shall (i)
ascertain the number of shares of capital stock of the corporation outstanding
and the voting power of each such share, (ii) determine the shares of capital
stock of the corporation represented at the meeting and the validity of proxies
and ballots, (iii) count all votes and ballots, (iv) determine and retain for a
reasonable period a record of the disposition of any challenges made to any
determination by the inspectors, and (v) certify their determination of the
number of shares of capital stock of the corporation represented at the meeting
and such inspector's or inspectors' count of all votes and ballots.  Such
certification and report shall specify such other information as may be required
by law.  In determining validity and counting of proxies and ballots cast at any
meeting of stockholders of the corporation, the inspectors may consider such
information as is permitted by applicable law.  No person who is a candidate for
an office at an election may serve as an inspector at such election.

          Section 1.12.  Conduct of Meetings.  The Board of Directors of the
                         -------------------                                
corporation may adopt by resolution such rules and regulations for the conduct
of the meeting of stockholders as it shall deem appropriate.  Except to the
extent inconsistent with such rules and regulations as adopted by the Board of
Directors, the person presiding over any meeting of stockholders shall have the
right and authority to prescribe such rules, regulations and procedures and to
do all such acts as, in the judgment of such person, are appropriate for the
proper conduct of the meeting.  Such rules, regulations or procedures, whether
adopted by the Board of Directors or prescribed by the person presiding over the
meeting, may include, without limitation, the following:  (i) the establishment
of an agenda or order of business for the meeting; (ii) rules and procedures for
maintaining order at the meeting and the safety of those present; (iii)
limitations on attendance at or participation in the meeting to stockholders of
record of the corporation, their duly authorized and constituted proxies or such
other persons as the person presiding over the meeting shall determine; (iv)
restrictions on entry to the meeting after the time fixed for the commencement
thereof; and (v) limitations on the time allotted to questions or comments by
participants.  Unless 

                                       4

 
and to the extent determined by the Board of Directors or the person presiding
over the meeting, meetings of stockholders shall not be required to be held in
accordance with the rules of parliamentary procedure.

should ultimately be determined that the indemnitee is not entitled to be
indemnified under this Article or otherwise.

          Section 6.3.  Claims.  If a claim for indemnification or advancement

disinterested directors or otherwise.

          Section 6.5.  Other Indemnification.  The corporation's obligation, if

any, to indemnify any person who was or is serving at its request as a director,
officer, employee or agent of another corporation, partnership, joint venture,
trust, enterprise or non-profit entity shall be reduced by any amount such
person may collect as indemnification from such other corporation, partnership,
joint venture, trust, enterprise or non-profit entity.

          Section 7.1.  Fiscal Year.  The fiscal year of the corporation shall
                        -----------

notice, whether before or after the time stated therein, shall be deemed
equivalent to notice. Attendance of a person at a meeting shall constitute a
waiver of notice of such meeting, except when the person 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, directors, or members of a
committee of directors need be specified in any written waiver of notice.

          Section 7.4.  Interested Directors; Quorum.  No contract or

transaction between the corporation and one (1) or more of its directors or
officers, or between the corporation and any other corporation, partnership,
association, or other organization in which one (1) or more of its directors or
officers are directors or officers, or have a financial interest, shall be void
or voidable solely for this reason, or solely because the director or officer is
present at or participates in the meeting of the Board of Directors or committee
thereof which authorizes the contract or transaction, or solely because his or
their votes are counted for such purpose, if:  (i)  the material facts as to his
relationship or interest and as to the contract or transaction are disclosed or
are known to the Board of Directors or the committee, and the Board of Directors
or committee in good faith authorizes the contract or transaction by the
affirmative votes of a majority of the disinterested directors, even though the
disinterested directors be less than a quorum; or (ii)  the material facts as to
his relationship or interest and as to the contract or transaction are disclosed
or are known to the stockholders entitled to vote thereon, and the contract or
transaction is specifically approved in good faith by vote of the stockholders;
or (iii) the contract or transaction is fair as to the corporation as of the
time it is authorized, approved or ratified, by the Board of Directors, a
committee thereof, or the stockholders.  Common or interested directors may be
counted in determining the presence of a quorum at a meeting of the Board of
Directors or of a committee which authorizes the contract or transaction.

microphotographs, or any other information storage device, provided that the
records so kept can be converted into clearly legible form within a reasonable
time.
          Section 7.6.  Amendment of By-Laws.  These by-laws may be altered or
                        --------------------                                  
repealed, and new by-laws made, by the Board of Directors to the extent
permitted by the certificate of incorporation, but the stockholders may make
additional by-laws and may alter and repeal any by-laws whether adopted by them
or otherwise.
