     SECTION 1.  Annual Meeting.  The annual meeting of stockholders shall be
                 --------------                                              
held at the hour, date and place within or without the United States which is
fixed by the majority of the Board of Directors, the Chairman of the Board, if
one is elected, or the President, which time, date and place may subsequently be
changed at any time by vote of the Board of Directors.  If no annual meeting has
been held for a period of thirteen months after the Corporation's last annual
meeting of stockholders, a special meeting in lieu thereof may be held, and such
special meeting shall have, for the purposes of these By-laws or otherwise, all
the force and effect of an annual meeting.  Any and all references hereafter in
these By-laws to an annual meeting or annual meetings also shall be deemed to
refer to any special meeting(s) in lieu thereof.
 
     SECTION 2.  Matters to be Considered at Annual Meetings.  At any annual
                 -------------------------------------------                
meeting of stockholders or any special meeting in lieu of annual meeting of
stockholders (the "Annual Meeting"), only such business shall be conducted, and
only such proposals shall be acted upon, as shall have been properly brought
before such Annual Meeting.  To be considered as properly brought before an
Annual Meeting, business must be:  (a) specified in the notice of meeting, (b)
otherwise properly brought before the meeting by, or at the direction of, the
Board of Directors, or (c) otherwise properly brought before the meeting by any
holder of record (both as of the time notice of such proposal is given by the
stockholder as set forth below and as of the record date for the Annual Meeting
in question) of any shares of capital stock of the Corporation entitled to vote
at such Annual Meeting who complies with the requirements set forth in this
Section 2.
 
     In addition to any other applicable requirements, for business to be
properly brought before an Annual Meeting by a stockholder of record of any
shares of capital stock entitled to vote at such Annual Meeting, such
stockholder shall:  (a) give timely notice as required by this Section 2 to the
Secretary of the Corporation and (b) be present at such meeting, either in
person or by a representative.  For the first Annual Meeting following the
initial public offering of common stock of the Corporation, a stockholder's
notice shall be timely if delivered to, or mailed to and received by, the
<PAGE>
 
Corporation at its principal executive office not later than the close of
business on the later of (a) the 75th day prior to the scheduled date of such
Annual Meeting or (b) the 15th day following the day on which public
announcement of the date of such Annual Meeting is first made or sent by the
Corporation.  For all subsequent Annual Meetings, a stockholder's notice shall
be timely if delivered to, or mailed to and received by, the Corporation at its
principal executive office not less than 75 days nor more than 120 days prior to
the anniversary date of the immediately preceding Annual Meeting (the
"Anniversary Date"); provided, however, that in the event the Annual Meeting is
                     --------  -------                                         
scheduled to be held on a date more than 30 days before the Anniversary Date or
more than 60 days after the Anniversary Date, a stockholder's notice shall be
timely if delivered to, or mailed to and received by, the Corporation at its
principal executive office not later than the close of business on the later of
(a) the 75th day prior to the scheduled date of such Annual Meeting or (b) the
15th day following the day on which public announcement of the date of such
Annual Meeting is first made by the Corporation.
 
     For purposes of these By-laws, "public announcement" shall mean:  (a)
disclosure in a press release reported by the Dow Jones News Service, Associated
Press or comparable national news service, (b) a report or other document filed
publicly with the Securities and Exchange Commission (including, without
limitation, a Form 8-K), or (c) a letter or report sent to stockholders of
record of the Corporation at the time of the mailing of such letter or report.
 
     A stockholder's notice to the Secretary shall set forth as to each matter
proposed to be brought before an Annual Meeting:  (a) a brief description of the
business the stockholder desires to bring before such Annual Meeting and the
reasons for conducting such business at such Annual Meeting, (b) the name and
address, as they appear on the Corporation's stock transfer books, of the
stockholder proposing such business, (c) the class and number of shares of the
Corporation's capital stock beneficially owned by the stockholder proposing such
business, (d) the names and addresses of the beneficial owners, if any, of any
capital stock of the Corporation registered in such stockholder's name on such
books, and the class and number of shares of the Corporation's capital stock
beneficially owned by such beneficial owners, (e) the names and addresses of
other stockholders known by the stockholder proposing such business to support
such proposal, and the class and number of shares of the Corporation's capital
stock beneficially owned by such other stockholders, and (f) any material
interest of the stockholder proposing to bring such business before such meeting
(or any other stockholders known to be supporting such proposal) in such
proposal.
 
     If the Board of Directors or a designated committee thereof determines that
any stockholder proposal was not made in a timely fashion in accordance with the
provisions of this Section 2 or that the information provided in a stockholder's
notice does not satisfy the information requirements of this Section 2 in any
material respect, such proposal shall not be presented for action at the Annual
Meeting in question.  If neither the Board of Directors nor such committee makes
a determination as to the 
<PAGE>
 
validity of any stockholder proposal in the manner set forth above, the
presiding officer of the Annual Meeting shall determine whether the stockholder
proposal was made in accordance with the terms of this Section 2. If the
presiding officer determines that any stockholder proposal was not made in a
timely fashion in accordance with the provisions of this Section 2 or that the
information provided in a stockholder's notice does not satisfy the information
requirements of this Section 2 in any material respect, such proposal shall not
be presented for action at the Annual Meeting in question. If the Board of
Directors, a designated committee thereof or the presiding officer determines
that a stockholder proposal was made in accordance with the requirements of this
Section 2, the presiding officer shall so declare at the Annual Meeting.
 
     Notwithstanding the foregoing provisions of this By-law, a stockholder
shall also comply with all applicable requirements of the Securities Exchange
Act of 1934, as amended (the "Exchange Act"), and the rules and regulations
thereunder with respect to the matters set forth in this Section 2, and nothing
in this Section 2 shall be deemed to affect any rights of stockholders to
request inclusion of proposals in the Corporation's proxy statement pursuant to
Rule 14a-8 under the Exchange Act.
 
     SECTION 3.  Special Meetings.  Except as otherwise required by law and
                 ----------------                                          
subject to the rights, if any, of the holders of any series of preferred stock,
special meetings of the stockholders of the Corporation may be called only by
the Chairman of the Board, if one is elected, or the Board of Directors pursuant
to a resolution approved by the affirmative vote of a majority of the directors
then in office.
 
     SECTION 4.  Matters to be Considered at Special Meetings.  Only those
                 --------------------------------------------             
matters set forth in the notice of the special meeting may be considered or
acted upon at a special meeting of stockholders of the Corporation, unless
otherwise provided by law.
 
     SECTION 5.  Notice of Meetings; Adjournments.  A written notice of each
                 --------------------------------                           
Annual Meeting stating the hour, date and place of such Annual Meeting shall be
given by the Secretary or an Assistant Secretary (or other person authorized by
these By-laws or by law) not less than 10 days nor more than 60 days before the
Annual Meeting, to each stockholder entitled to vote thereat and to each
stockholder who, by law or under the Certificate of Incorporation of the
Corporation (as the same may hereafter be amended and/or restated, the
"Certificate") or under these By-laws, is entitled to such notice, by delivering
such notice to him or by mailing it, postage prepaid, addressed to such
stockholder at the address of such stockholder as it appears on the
Corporation's stock transfer books.  Such notice shall be deemed to be given
when hand delivered to such address or deposited in the mail so addressed, with
postage prepaid.
 
     Notice of all special meetings of stockholders shall be given in the same
manner as provided for Annual Meetings, except that the written notice of all
special meetings shall state the purpose or purposes for which the meeting has
been called.
<PAGE>
 
     Notice of an Annual Meeting or special meeting of stockholders need not be
given to a stockholder if a written waiver of notice is signed before or after
such meeting by such stockholder or if such stockholder attends such meeting,
unless such attendance was for the express purpose of objecting at the beginning
of the meeting to the transaction of any business because the meeting was not
lawfully called or convened.  Neither the business to be transacted at, nor the
purpose of, any Annual Meeting or special meeting of stockholders need be
specified in any written waiver of notice.
 
     The Board of Directors may postpone and reschedule any previously scheduled
Annual Meeting or special meeting of stockholders and any record date with
respect thereto, regardless of whether any notice or public disclosure with
respect to any such meeting has been sent or made pursuant to Section 2 of this
Article I or Section 3 of Article II hereof or otherwise.   In no event shall
the public announcement of an adjournment, postponement or rescheduling of any
previously scheduled meeting of stockholders commence a new time period for the
giving of a stockholder's notice under Section 2 of Article I and Section 3 of
Article II of these By-laws.
 
     When any meeting is convened, the presiding officer may adjourn the meeting
if (a) no quorum is present for the transaction of business, (b) the Board of
Directors determines that adjournment is necessary or appropriate to enable the
stockholders to consider fully information which the Board of Directors
determines has not been made sufficiently or timely available to stockholders,
or (c) the Board of Directors determines that adjournment is otherwise in the
best interests of the Corporation.  When any Annual Meeting or special meeting
of stockholders is adjourned to another hour, date or place, notice need not be
given of the adjourned meeting other than an announcement at the meeting at
which the adjournment is taken of the hour, date and place to which the meeting
is adjourned; provided, however, that if the adjournment is for more than 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 thereat and each stockholder who, by law or under the
Certificate or these By-laws, is entitled to such notice.
 
     SECTION 6.  Quorum.  The holders of shares of voting stock representing a
                 ------                                                       
majority of the voting power of the outstanding shares of voting stock issued,
outstanding and entitled to vote at a meeting of stockholders, represented in
person or by proxy at such meeting, shall constitute a quorum; but if less than
a quorum is present at a meeting, the holders of voting stock representing a
majority of the voting power present at the meeting or the presiding officer may
adjourn the meeting from time to time, and the meeting may be held as adjourned
without further notice, except as provided in Section 5 of this Article I.  At
such adjourned meeting at which a quorum is present, any business may be
transacted which might have been transacted at the meeting as originally
noticed.  The stockholders present at a duly constituted meeting may continue to
transact business until adjournment, notwithstanding the withdrawal of enough
stockholders to leave less than a quorum.
<PAGE>
 
     SECTION 7.  Voting and Proxies.  Stockholders shall have one vote for each
                 ------------------                                            
share of stock entitled to vote owned by them of record according to the books
of the Corporation, unless otherwise provided by law or by the Certificate.
Stockholders may vote either in person or by proxy, but no proxy shall be voted
or acted upon after three years from its date, unless the proxy provides for a
longer period.  Proxies shall be filed with the Secretary of the meeting before
being voted.  Except as otherwise limited therein or as otherwise provided by
law, proxies shall entitle the persons authorized thereby to vote at any
adjournment of such meeting, but they shall not be valid after final adjournment
of such meeting.  A proxy with respect to stock held in the name of two or more
persons shall be valid if executed by or on behalf of any one of them unless at
or prior to the exercise of the proxy the Corporation receives a specific
written notice to the contrary from any one of them.  A proxy purporting to be
executed by or on behalf of a stockholder shall be deemed valid, and the burden
of proving invalidity shall rest on the challenger.
 
     SECTION 8.  Action at Meeting.  When a quorum is present, any matter before
                 -----------------                                              
any meeting of stockholders shall be decided by the vote of a majority of the
voting power of shares of voting stock present in person or represented by proxy
at such meeting and entitled to vote on such matter, except where a larger vote
is required by law, by the Certificate or by these By-laws.  Any election of
directors by stockholders shall be determined by a plurality of the votes cast,
except where a larger vote is required by law, by the Certificate or by these
By-laws.  The Corporation shall not directly or indirectly vote any shares of
its own stock that belong to the Corporation; provided, however, that the
                                              --------  -------          
Corporation may vote shares which it holds in a fiduciary capacity to the extent
permitted by law.
 
     SECTION 9.  Stockholder Lists.  The Secretary or an Assistant Secretary (or
                 -----------------                                              
the Corporation's transfer agent or other person authorized by these By-laws or
by law) shall prepare and make, at least 10 days before every Annual Meeting or
special 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, 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 hour, date and place of
the meeting during the whole time thereof, and may be inspected by any
stockholder who is present.
 
     SECTION 10.  Presiding Officer.  The Chairman of the Board, if one is
                  -----------------                                       
elected, or if not elected or in his or her absence, the President, shall
preside at all Annual Meetings or special meetings of stockholders and shall
have the power, among other things, to adjourn such meeting at any time and from
time to time, subject to Sections 5 
<PAGE>
 
and 6 of this Article I. The order of business and all other matters of
procedure at any meeting of the stockholders shall be determined by the
presiding officer.
<PAGE>
 
     SECTION 11.  Voting Procedures and Inspectors of Elections.  The
                  ---------------------------------------------      
Corporation shall, in advance of any meeting of stockholders, appoint one or
more inspectors to act at the meeting and make a written report thereof.  The
Corporation may designate one or more persons as alternate inspectors to replace
any inspector who fails to act.  If no inspector or alternate is able to act at
a meeting of stockholders, the presiding officer shall appoint one or more
inspectors to act at the meeting.  Any inspector may, but need not, be an
officer, employee or agent of the Corporation.  Each inspector, before entering
upon the discharge of his or her duties, shall take and sign an oath faithfully
to execute the duties of inspector with strict impartiality and according to the
best of his or her ability.  The inspectors shall perform such duties as are
required by the General Corporation Law of the State of Delaware, as amended
from time to time (the "DGCL"), including the counting of all votes and ballots.
The inspectors may appoint or retain other persons or entities to assist the
inspectors in the performance of the duties of the inspectors.  The presiding
officer may review all determinations made by the inspectors, and in so doing
the presiding officer shall be entitled to exercise his or her sole judgment and
discretion and he or she shall not be bound by any determinations made by the
inspectors.  All determinations by the inspectors and, if applicable, the
presiding officer, shall be subject to further review by any court of competent
jurisdiction.

                                  ----------
                                        
                                   Directors
                                   ---------
 
     SECTION 1.  Powers.  The business and affairs of the Corporation shall be
                 ------                                                       
managed by or under the direction of the Board of Directors except as otherwise
provided by the Certificate or required by law.
 
     SECTION 2.  Number and Terms.  The number of directors of the Corporation
                 ----------------                                             
shall be fixed by resolution duly adopted from time to time by the Board of
Directors.  The directors shall hold office in the manner provided in the
Certificate.
 
     SECTION 3.  Director Nominations.  Nominations of candidates for election
                 --------------------                                         
as directors of the Corporation at any Annual Meeting may be made only (a) by,
or at the direction of, a majority of the Board of Directors or (b) by any
holder of record (both as of the time notice of such nomination is given by the
stockholder as set forth below and as of the record date for the Annual Meeting
in question) of any shares of the capital stock of the Corporation entitled to
vote at such Annual Meeting who complies with the timing, informational and
other requirements set forth in this Section 3.  Any stockholder who has
complied with the timing, informational and other requirements set forth in this
Section 3 and who seeks to make such a nomination, or his, her or its
representative, must be present in person at the Annual Meeting.  Only persons
nominated in accordance with the procedures set forth in this Section 3 shall be
eligible for election as directors at an Annual Meeting.
<PAGE>
 
     Nominations, other than those made by, or at the direction of, the Board of
Directors, shall be made pursuant to timely notice in writing to the Secretary
of the Corporation as set forth in this Section 3.  For the first Annual Meeting
following the initial public offering of common stock of the Corporation, a
stockholder's notice shall be timely if delivered to, or mailed to and received
by, the Corporation at its principal executive office not later than the close
of business on the later of (a) the 75th day prior to the scheduled date of such
Annual Meeting or (b) the 15th day following the day on which public
announcement of the date of such Annual Meeting is first made or sent by the
Corporation.  For all subsequent Annual Meetings, a stockholder's notice shall
be timely if delivered to, or mailed to and received by, the Corporation at its
principal executive office not less than 75 days nor more than 120 days prior to
the Anniversary Date; provided, however, that in the event the Annual Meeting is
                      --------  -------                                         
scheduled to be held on a date more than 30 days before the Anniversary Date or
more than 60 days after the Anniversary Date, a stockholder's notice shall be
timely if delivered to, or mailed and received by, the Corporation at its
principal executive office not later than the close of business on the later of
(a) the 75th day prior to the scheduled date of such Annual Meeting or (b) the
15th day following the day on which public announcement of the date of such
Annual Meeting is first made by the Corporation.
 
     A stockholder's notice to the Secretary shall set forth as to each person
whom the stockholder proposes to nominate for election or re-election as a
director:  (a) the name, age, business address and residence address of such
person, (b) the principal occupation or employment of such person, (c) the class
and number of shares of the Corporation's capital stock which are beneficially
owned by such person on the date of such stockholder notice, and (d) the consent
of each nominee to serve as a director if elected.  A stockholder's notice to
the Secretary shall further set forth as to the stockholder giving such notice:
(a) the name and address, as they appear on the Corporation's stock transfer
books, of such stockholder and of the beneficial owners (if any) of the
Corporation's capital stock registered in such stockholder's name and the name
and address of other stockholders known by such stockholder to be supporting
such nominee(s), (b) the class and number of shares of the Corporation's capital
stock which are held of record, beneficially owned or represented by proxy by
such stockholder and by any other stockholders known by such stockholder to be
supporting such nominee(s) on the record date for the Annual Meeting in question
(if such date shall then have been made publicly available) and on the date of
such stockholder's notice, and (c) a description of all arrangements or
understandings between such stockholder and each nominee and any other person or
persons (naming such person or persons) pursuant to which the nomination or
nominations are to be made by such stockholder.
 
     If the Board of Directors or a designated committee thereof determines that
any stockholder nomination was not made in accordance with the terms of this
Section 3 or that the information provided in a stockholder's notice does not
satisfy the informational requirements of this Section 3 in any material
respect, then such 
<PAGE>
 
nomination shall not be considered at the Annual Meeting in question. If neither
the Board of Directors nor such committee makes a determination as to whether a
nomination was made in accordance with the provisions of this Section 3, the
presiding officer of the Annual Meeting shall determine whether a nomination was
made in accordance with such provisions. If the presiding officer determines
that any stockholder nomination was not made in a timely fashion in accordance
with the terms of this Section 3 or that the information provided in a
stockholder's notice does not satisfy the informational requirements of this
Section 3 in any material respect, then such nomination shall not be considered
at the Annual Meeting in question. If the Board of Directors, a designated
committee thereof or the presiding officer determines that a nomination was made
in accordance with the terms of this Section 3, the presiding officer shall so
declare at the Annual Meeting and ballots shall be provided for use at the
meeting with respect to such nominee.
 
     Notwithstanding anything to the contrary in the second sentence of the
second paragraph of this Section 3, in the event that the number of directors to
be elected to the Board of Directors of the Corporation is increased and there
is no public announcement by the Corporation naming all of the nominees for
director or specifying the size of the increased Board of Directors at least 75
days prior to the Anniversary Date, a stockholder's notice required by this
Section 3 shall also be considered timely, but only with respect to nominees for
any new positions created by such increase, if such notice shall be delivered
to, or mailed to and received by, the Corporation at its principal executive
office not later than the close of business on the 15th day following the day on
which such public announcement is first made by the Corporation.
 
     No person shall be elected by the stockholders as a director of the
Corporation unless nominated in accordance with the procedures set forth in this
Section.  Election of directors at an Annual Meeting need not be by written
ballot, unless otherwise provided by the Board of Directors or presiding officer
at such Annual Meeting.  If written ballots are to be used, ballots bearing the
names of all the persons who have been nominated for election as directors at
the Annual Meeting in accordance with the procedures set forth in this Section
shall be provided for use at the Annual Meeting.
 
     SECTION 4.  Qualification.  No director need be a stockholder of the
                 -------------                                           
Corporation.
 
     SECTION 5.  Vacancies.  Subject to the rights, if any, of the holders of
                 ---------                                                   
any series of preferred stock to elect directors and to fill vacancies in the
Board of Directors relating thereto, any and all vacancies in the Board of
Directors, however occurring, including, without limitation, by reason of an
increase in size of the Board of Directors, or the death, resignation,
disqualification or removal of a director, shall be filled solely by the
affirmative vote of a majority of the remaining directors then in office, even
if less than a quorum of the Board of Directors.  Any director appointed in
accordance with the preceding sentence shall hold office for the remainder of
the full term of the class of directors in which the new directorship was
created or the vacancy occurred 
<PAGE>
 
and until such director's successor shall have been duly elected and qualified
or until his or her earlier resignation or removal. Subject to the rights, if
any, of the holders of any series of preferred stock to elect directors, when
the number of directors is increased or decreased, the Board of Directors shall
determine the class or classes to which the increased or decreased number of
directors shall be apportioned; provided, however, that no decrease in
                                --------  ------- 
the number of directors shall shorten the term of any incumbent director. 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 of
Directors until the vacancy is filled.
 
     SECTION 6.  Removal.  Directors may be removed from office in the manner
                 -------                                                     
provided in the Certificate.
 
     SECTION 7.  Resignation.  A director may resign at any time by giving
                 -----------                                              
written notice to the Chairman of the Board, if one is elected, the President or
the Secretary.  A resignation shall be effective upon receipt, unless the
resignation otherwise provides.
 
     SECTION 8.  Regular Meetings.  The regular annual meeting of the Board of
                 ----------------                                             
Directors shall be held, without notice other than this Section 8, on the same
date and at the same place as the Annual Meeting following the close of such
meeting of stockholders.  Other regular meetings of the Board of Directors may
be held at such hour, date and place as the Board of Directors may by resolution
from time to time determine without notice other than such resolution.
 
     SECTION 9.  Special Meetings.  Special meetings of the Board of Directors
                 ----------------                                             
may be called, orally or in writing, by or at the request of a majority of the
directors, the Chairman of the Board, if one is elected, or the Chief Executive
Officer.  The person calling any such special meeting of the Board of Directors
may fix the hour, date and place thereof.
 
     SECTION 10.  Notice of Meetings.  Notice of the hour, date and place of all
                  ------------------                                            
special meetings of the Board of Directors shall be given to each director by
the Secretary or an Assistant Secretary, or in case of the death, absence,
incapacity or refusal of such persons, by the Chairman of the Board, if one is
elected, or the President or such other officer designated by the Chairman of
the Board, if one is elected, or the President.  Notice of any special meeting
of the Board of Directors shall be given to each director in person, by
telephone, or by facsimile, telex, telecopy, telegram, or other written form of
electronic communication, sent to his or her business or home address, at least
24 hours in advance of the meeting, or by written notice mailed to his or her
business or home address, at least 48 hours in advance of the meeting.  Such
notice shall be deemed to be delivered when hand delivered to such address, read
to such director by telephone, deposited in the mail so addressed, with postage
thereon prepaid if mailed, dispatched or transmitted if faxed, telexed or
telecopied, or when delivered to the telegraph company if sent by telegram.
<PAGE>
 
     When any Board of Directors meeting, either regular or special, is
adjourned for 30 days or more, notice of the adjourned meeting shall be given as
in the case of an original meeting.  It shall not be necessary to give any
notice of the hour, date or place of any meeting adjourned for less than 30 days
or of the business to be transacted thereat, other than an announcement at the
meeting at which such adjournment is taken of the hour, date and place to which
the meeting is adjourned.
 
     A written waiver of notice signed before or after a meeting by a director
and filed with the records of the meeting shall be deemed to be equivalent to
notice of the meeting.  The attendance of a director at a meeting shall
constitute a waiver of notice of such meeting, except where a director attends a
meeting for the express purpose of objecting at the beginning of the meeting to
the transaction of any business because such meeting is not lawfully called or
convened.  Except as otherwise required by law, by the Certificate or by these
By-laws, neither the business to be transacted at, nor the purpose of, any
meeting of the Board of Directors need be specified in the notice or waiver of
notice of such meeting.
 
     SECTION 11.  Quorum.  At any meeting of the Board of Directors, a majority
                  ------                                                       
of the directors then in office shall constitute a quorum for the transaction of
business, but if less than a quorum is present at a meeting, a majority of the
directors present may adjourn the meeting from time to time, and the meeting may
be held as adjourned without further notice, except as provided in Section 10 of
this Article II.  Any business which might have been transacted at the meeting
as originally noticed may be transacted at such adjourned meeting at which a
quorum is present.
 
     SECTION 12.  Action at Meeting.  At any meeting of the Board of Directors
                  -----------------                                           
at which a quorum is present, a majority of the directors present may take any
action on behalf of the Board of Directors, unless otherwise required by law, by
the Certificate or by these By-laws.
 
     SECTION 13.  Action by Consent.  Any action required or permitted to be
                  -----------------                                         
taken at any meeting of the Board of Directors may be taken without a meeting if
all members of the Board of Directors consent thereto in writing.  Such written
consent shall be filed with the records of the meetings of the Board of
Directors and shall be treated for all purposes as a vote at a meeting of the
Board of Directors.

                 ----------------------------------------                 
operation of Section 4 of this Article V, each Non-Officer Employee may, in the

Officer Employee or on such Non-Officer Employee's behalf in connection with any
threatened, pending or completed Proceeding, or any claim, issue or matter
therein, which such Non-Officer Employee is, or is threatened to be made, a
party to or participant in by reason of such Non-Officer Employee's Corporate
Status, if such Non-Officer Employee acted in good faith and in a manner such
Non-Officer Employee reasonably believed to be in or not opposed to the best
interests of the Corporation and, with respect to any criminal proceeding, had
no reasonable cause to believe his or her conduct was unlawful.  The rights of

designated by a majority vote of the Disinterested Directors (even though less

<PAGE>
 
Director's Corporate Status within 10 days after the receipt by the Corporation
of a written statement from such Director requesting such advance or advances
from time to time, whether prior to or after final disposition of such
Proceeding. Such statement or statements shall reasonably evidence the Expenses
incurred by such Director and shall be preceded or accompanied by an undertaking
by or on behalf of such Director to repay any Expenses so advanced if it shall
ultimately be determined that such Director is not entitled to be indemnified
against such Expenses.

                 -------------------------------------------------------------
Prior to Final Disposition.
- --------------------------

the Board of Directors of the Corporation, advance any or all Expenses incurred
by or on behalf of any Officer in connection with any Proceeding in which such
is involved by reason of such Officer's Corporate Status upon the receipt by the
Corporation of a statement or statements from such Officer requesting such
advance or advances from time to time, whether prior to or after final
disposition of such Proceeding.  Such statement or statements shall reasonably
evidence the Expenses incurred by such Officer and shall be preceded or
accompanied by an undertaking by or on behalf of such to repay any Expenses so
advanced if it shall ultimately be determined that such Officer is not entitled
to be indemnified against such Expenses.
 
     (b)  Advancement to Non-Officer Employees.  The Corporation may, at the
          ------------------------------------                              
discretion of the Board of Directors or of any Officer who is authorized to act
on behalf of the Corporation, advance any or all Expenses incurred by or on
behalf of any Non-Officer Employee in connection with any Proceeding in which
such Non-Officer Employee is involved by reason of such Non-Officer Employee's
Corporate Status upon the receipt by the Corporation of a statement or
statements from such Non-Officer Employee requesting such advance or advances
from time to time, whether prior to or after final disposition of such
Proceeding.  Such statement or statements shall reasonably evidence the Expenses
incurred by such Non-Officer Employee and shall be preceded or accompanied by an
undertaking by or on behalf of such Non-Officer Employee to repay any Expenses
so advanced if it shall ultimately be determined that such Non-Officer Employee
is not entitled to be indemnified against such Expenses.
 
     SECTION 7.  Contractual Nature of Rights.  The foregoing provisions of this
                 ----------------------------                                   
Article V shall be deemed to be a contract between the Corporation and each
Director and Officer entitled to the benefits hereof at any time while this
Article V is in effect, and any repeal or modification thereof shall not affect
any rights or obligations then existing with respect to any state of facts then
or theretofore existing or any Proceeding theretofore or thereafter brought
based in whole or in part upon any such state of facts.  If a claim for
indemnification or advancement of Expenses hereunder by a Director or Officer is
not paid in full by the Corporation within (a) 60 days after receipt by the
Corporation of a written claim for indemnification, or (b) in the case of a
Director, 10 days after receipt by the Corporation of documentation of Expenses
and the required 
<PAGE>
 
undertaking, such Director or Officer may at any time thereafter bring suit
against the Corporation to recover the unpaid amount of the claim, and if
successful in whole or in part, such Director or Officer shall also be entitled
to be paid the expenses of prosecuting such claim. The failure of the
Corporation (including its Board of Directors or any committee thereof,
independent legal counsel, or stockholders) to make a determination concerning
the permissibility of such indemnification or, in the case of a Director,
advancement of Expenses, under this Article V shall not be a defense to the
action and shall not create a presumption that such indemnification or
advancement is not permissible.
 
     SECTION 8.  Non-Exclusivity of Rights.  The rights to indemnification and
                 -------------------------                                    
advancement of Expenses set forth in this Article V shall not be exclusive of
any other right which any Director, Officer, or Non-Officer Employee may have or
hereafter acquire under any statute, provision of the Certificate or these By-
laws, agreement, vote of stockholders or Disinterested Directors or otherwise.
<PAGE>
 
     SECTION 9.  Insurance.  The Corporation may maintain insurance, at its
                 ---------                                                 
expense, to protect itself and any Director, Officer or Non-Officer Employee
against any liability of any character asserted against or incurred by the
Corporation or any such Director, Officer or Non-Officer Employee, or arising
out of any such person's Corporate Status, whether or not the Corporation would
have the power to indemnify such person against such liability under the DGCL or
the provisions of this Article V.
