stockholders, only such business shall be conducted as shall have been properly

business must be specified in the notice of meeting (or any supplement thereto)
given by or at the direction of the Board of Directors, otherwise properly
brought before the meeting by or at the direction of the Board of Directors or
otherwise properly brought before the meeting by a stockholder.  In addition to
any other applicable requirements, for business to be properly brought before an
annual meeting by a stockholder, the stockholder must have given timely notice
thereof in writing to the Secretary of the Corporation.  To be timely, a
stockholder's notice must be delivered to or mailed and received at the
principal executive offices of the Corporation, not less than sixty days nor
more than ninety days prior to the meeting; provided, however, that in the event
that less than seventy days' notice or prior public disclosure of the date of
the meeting is given or made to stockholders, notice by the stockholder to be
timely must be so received not later than the close of business on the tenth day
following the day on which such notice of the date of the 

                                       2
<PAGE>
 
annual meeting was mailed or such public disclosure was made. A stockholder's

business desired to be brought before the annual meeting and the reasons for
conducting such business at the annual meeting, (ii) the name and record address

stockholder and any material interest of the stockholder in such business, and
(v) a representation that the stockholder intends to appear in person or by
proxy at the annual meeting to bring such business before the meeting.

     Notwithstanding anything in the Bylaws to the contrary, no business shall
be conducted at the annual meeting except in accordance with the procedures set
forth in this Article II, Section 11, provided, however, that nothing in this
Article II, Section 11 shall be deemed to preclude discussion by any stockholder
of any business properly brought before the annual meeting in accordance with
said procedure.

     The Chairman of an annual meeting shall, if the facts warrant, determine
and declare to the meeting that business was not properly brought before the
meeting in accordance with the provisions of this Article II, Section 11, and if
he should so determine, he shall so declare to the meeting and any such business
not properly brought before the meeting shall not be transacted.

     Section 12.  Nominations of Persons for Election to the Board of Directors.
                  ------------------------------------------------------------- 
In addition to any other applicable requirements, only persons who are nominated
in accordance with the following procedures shall be eligible for election as
Directors.  Nominations of persons for election to the Board of Directors of the
Corporation may be made at a meeting of stockholders by or at the direction of
the Board of Directors, by any nominating committee or person appointed by the
Board of Directors or by any stockholder of the Corporation entitled to vote for
the election of Directors at the meeting who complies with the notice procedures
set forth in this Article II, Section 12.  Such 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.  To be timely, a
stockholder's notice shall be delivered to or mailed and received at the
principal executive offices of the Corporation not less than sixty days nor more
than ninety days prior to the meeting; provided, however, that in the event that
less than seventy days' notice or prior public disclosure of the date of the
meeting is given or made to stockholders, notice by the stockholders to be
timely must be so received not later than the close of business on the tenth day
following the day on which such notice of the date of the meeting was mailed or
such public disclosure was made.  Such stockholder's notice shall set forth (a)
as to each person whom the stockholder proposes to nominate for election or re-
election as a Director, (i) the name, age, business address and residence
address of the person, (ii) the principal occupation or employment of the
person, (iii) the class and number of shares of the Corporation which are
beneficially owned by the person and (iv) any other information relating to the
person that is required to be disclosed in solicitations for proxies for
election of Directors pursuant to Section 14 of the Securities Exchange Act of
1934, as amended (the "Exchange Act"), and the rules and regulations promulgated
thereunder; and (b) as to the stockholder giving the notice, (i) the name and
record address of the stockholder, (ii) the class or series and number of shares
of capital stock of the Corporation which are owned beneficially or of record by
the stockholder, (iii) a description of all arrangements or understandings
between the stockholder and each proposed nominee and any other person or
persons (including their names) pursuant to which the nominations(s) are to be
made by the stockholder, (iv) a representation that such stockholder intends to
appear in person or by proxy at the meeting to nominate the persons named in
such notice and (v) any other information relating to the stockholder that would
be required to be disclosed in a proxy statement or other filings required to be
made in connection with solicitations of proxies for the election of Directors
pursuant to Section 14 of the Exchange Act and the rules and regulations
promulgated thereunder.  Such notice must be accompanied by a written consent of
each proposed nominee being named as a nominee and to serve as a Director if
elected.  The Corporation may 

                                       3
<PAGE>
 
require any proposed nominee to furnish such other information as may reasonably
be required by the Corporation to determine the eligibility of such proposed
nominee to serve as a Director of the Corporation. No person shall be eligible
for election as a Director of the Corporation unless nominated in accordance
with the procedures set forth herein. The provisions of this Article II, Section
12 shall not apply to Directors governed by Section 14 of Article III.

     The Chairman of the meeting shall, if the facts warrant, determine and
declare to the meeting that a nomination was not made in accordance with the
foregoing procedure, and if he should so determine, he shall so declare to the
meeting and the defective nomination shall be disregarded.


                                  ARTICLE III
                                   DIRECTORS

     Section 1.  General Powers.  The business of the Corporation shall be
                 --------------                                           
managed by or under the direction of its Board of Directors which may exercise
all such powers of the Corporation and do all such lawful acts and things as are
not by law or by the Certificate of Incorporation or by these Bylaws directed or
required to be exercised or done by the stockholders.

     Section 2.  Number and Term of Office; Removal.  The number of Directors of
                 ----------------------------------                             
the Corporation shall be fixed from time to time by these Bylaws.  Until these
Bylaws are further amended, the number of Directors shall be no less than nine,
and no more than fifteen.  The Directors shall be divided into three classes.
Each such class shall consist, as nearly as may be possible, of one-third of the
total number of Directors, and any remaining Directors shall be included within
such group or groups as the Board of Directors shall designate.  The first class
will be elected for a term which expires in 1996.  The second class will be
elected for a term which expires in 1997.  The third class will be elected for a
term which expires in 1998.  At each annual meeting of stockholders, successors
to the class of Directors whose term expires at that annual meeting shall be
elected for a three-year term.  If the number of Directors is changed, any
increase or decrease shall be apportioned among the classes so as to maintain
the number of Directors in each class as nearly equal as possible, but in no
case shall a decrease in the number of Directors shorten the term of any
incumbent Director.  A Director may be removed from office for cause only and,
subject to such removal, death, resignation, retirement or disqualification,
shall hold office until the annual meeting of stockholders for the year in which
his term expires and until his successor shall be elected and qualify.  No
alteration, amendment or repeal of these Bylaws shall be effective to shorten
the term of any Director holding office at the time of such alteration,
amendment or repeal, to permit any such Director to be removed without cause, or
to increase the number of Directors in any class or in the aggregate from that
existing at the time of such alteration, amendment or repeal until the
expiration of the terms of office of all Directors then holding office, unless
such alteration, amendment or repeal has been approved by either the holders of
all shares of stock entitled to vote thereon or by a vote of a majority of the
entire Board of Directors.  The provisions of this Section 2 shall not apply to
Directors governed by Section 14 of this Article III.

     Section 3.  Vacancies.  Vacancies and newly created directorships resulting
                 ---------                                                      
from any increase in the authorized number of Directors may be filled by a
majority of the Directors then in office, though less than a quorum, or by a
sole remaining Director, in accordance with the provisions of the Certificate of
Incorporation, and the Directors so chosen shall hold office until the next
annual election and until their successors are duty elected and shall qualify,
unless sooner displaced.  If there are no Directors in office, then an election
of Directors may be held in the manner provided by law.  If, at the time of
filling any vacancy or any newly created directorship, 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 of the State of
Delaware may, upon application of any stockholder or stockholders holding at
least ten percent of the total number of the shares at the time outstanding
having the right to vote for such Directors, summarily order an election to 

                                       4
<PAGE>
 
be held to fill any such vacancies or newly created directorships, or to replace
the Directors chosen by the Directors then in office.

     Section 4.  Meetings.  The Board of Directors of the Corporation may hold
                 --------                                                     
meetings, both regular and special, either within or without the State of
Delaware.

     Section 5.  Initial Meeting.  The first meeting of each newly elected Board
                 ---------------                                                
of Directors shall be held at such time and place as shall be fixed by the vote
of the stockholders at the annual meeting of stockholders and no notice of such
meeting shall be necessary to the newly elected Directors in order legally to
constitute the meeting, provided a quorum shall be present.  In the event of the
failure of the stockholders to fix the time or place of such first meeting of
the newly elected Board of Directors, or in the event such meeting is not held
at the time and place so fixed by the stockholders, the meeting may be held at
such time and place as shall be specified in a notice given as hereinafter
provided for special meetings of the Board of Directors, or as shall be
specified in a written waiver signed by all of the Directors.

     Section 6.  Regular Meetings.  Regular meetings of the Board of Directors

time be determined by the Board of Directors.

                 ----------------                                             
may be called by the President on two days' notice to each Director, either
personally or by mail telegram or facsimile transmission; special meetings shall
be called by the President or Secretary in like manner and on like notice on the
written request of two Directors unless the Board of Directors consists of only
one Director, in which case special meetings shall be called by the President or
Secretary in like manner and on like notice on the written request of the sole
Director.

     Section 8.  Quorum and Meetings.  At all meetings of the Board of
                 -------------------                                  
Directors, a majority of the 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.  The Chairman of the Board, or his designee, shall
preside at all meetings of the Board of Directors and, whether or not a quorum
is present, may adjourn the meeting from time to time without notice other than
by announcement at the meeting.

     Section 9.  Unanimous Consent.  Unless otherwise restricted by the
                 -----------------

Certificate of Incorporation or these Bylaws, members of the Board of Directors,
or any committee designated by the Board of Directors, may participate in a
meeting of the Board of Directors, or any committee, by means of conference
telephone or similar communications equipment by means of which all persons
participating in the meeting can hear each other, and such participation in a
meeting shall constitute presence in person at the meeting.

     Section 11.  Committees.  The Board of Directors may, by resolution passed
                  ----------                                                   
by a majority of the whole Board of Directors, designate one or more committees,
each committee to consist of one or more of the Directors of the Corporation.
The Board of Directors 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.  Any such committee, to the extent provided in the
resolution of the Board of Directors, 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 to be
affixed to all papers which may require it; but no such committee shall have the

Corporation Law of the State of Delaware, fix any of the preferences or rights
of such shares relating to dividends, redemption, dissolution, any distribution
of assets of the Corporation or the conversion into, or the exchange of such
shares for, shares of any other class or classes or any other series of the same
or any other class or classes of stock of the Corporation), adopting an
agreement of merger or consolidation, recommending to the stockholders the sale,
lease or exchange of all or substantially all of the Corporation's property and
assets, recommending to the stockholders a dissolution of the Corporation or a
revocation of a dissolution, or amending the Bylaws; and, unless the resolution
or the Certificate of Incorporation expressly so provides, no such committee
shall have the power or authority to declare a dividend or to authorize the
issuance of stock or to adopt a certificate of ownership and merger. Such
committee or committees shall have such name or names as may be determined from
time to time by resolution adopted by the Board of Directors.

     Section 12.  Minutes.  Each committee shall keep regular minutes of its
                  -------

that any holders of any class or series of stock other than the Common Stock

be deemed to constitute an additional class of Directors and shall have a term
of office for one year or such other period as may be designated by the
provisions of such class or series providing such separate voting right to the
holders of such class or series of stock, and any such class of Directors shall
be in addition to the classes referred to in Section 2 of this Article III.  Any
Directors so elected shall be subject to removal in such manner as may be
provided by law or by the Certificate of Incorporation.  The provisions of

                 ------------------                                    
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 of any change, conversion or exchange of stock or
for the purpose of any other lawful action, the Board of Directors may fix, in
advance, a record date, which shall not be more than sixty nor less than ten
days before the date of such meeting, nor more than sixty days prior to any

other person, whether or not it shall have express or other notice thereof,

                                 ARTICLE VIII
                                   DIVIDENDS

     Section 1.  Paying Dividends.  The Board of Directors may from time to time
                 ----------------                                               
declare, and the Corporation may pay, dividends on the outstanding shares of the
Corporation in the manner and upon the terms and conditions provided by law and
by the Certificate of Incorporation of the Corporation or any amendments
thereto.  Dividends may be paid in cash, in property, or in shares of the
capital stock, subject to the provisions of the Certificate of Incorporation.

     Section 2.  Setting Aside Funds.  Before payment of any dividend, there may
                 -------------------                                            
be set aside out of any funds of the Corporation available for dividends such
sum or sums as the Directors from time to time, in their absolute discretion,
think proper as a reserve or reserves to meet contingencies, or for equalizing
dividends, or for repairing or maintaining any property of the Corporation, or
for such other purpose as the Directors shall think conducive to the interest of
the Corporation, and the Directors may modify or abolish any such reserve in the
manner in which it was created.


                                  ARTICLE IX
                                INDEMNIFICATION

     Section 1.  Mandatory Indemnification of Directors and Officers.
                 --------------------------------------------------- 

          (a) The Corporation shall indemnify, and shall pay in advance the
expenses of, each Director and officer of the Corporation and each person who is
serving at the request of the Corporation as a director or officer of another
corporation, partnership, joint venture, trust or other enterprise to the
fullest extent permissible under Delaware law, as the same exists or may
hereafter exist in the future (but, in the case of any future change, only to
the extent that such change permits the Corporation to provide broader
indemnification rights than the law permitted prior to such change) and such
obligation to indemnify and to advance expenses shall continue as to a person
who has ceased to be a Director or officer of the Corporation or a director or
officer of any other such corporation, partnership, joint venture, trust or
other enterprise and shall inure to the benefit of his or her heirs, executors
and administrators.

          (b) If a claim under Section 1(a) of this Article IX is not paid in
full by the Corporation within thirty (30) days after a written claim has been
received by the Corporation, the claimant 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, the claimant shall be entitled to be paid also
the expense of prosecuting such claim.  Neither the failure of the Corporation
(including its Board of Directors, independent legal counsel or its
stockholders) to have made a determination that indemnification of the claimant
is permissible in the circumstances because the claimant has met the applicable
standard of conduct, if any, nor an actual determination by the Corporation
(including its Board of Directors, independent legal counsel or its
stockholders) that the claimant has not met the standard of conduct, shall be a
defense to the action or create a presumption that the claimant has not met the
standard of conduct.

     Section 2.  Discretionary Indemnification of Employees and Agents.  The
                 -----------------------------------------------------      
Corporation may, but shall have no obligation to, indemnify and may pay in
advance the expenses of employees and agents of the Corporation and persons who
are serving at the request of the Corporation as an employee or agent of another

                                       9
<PAGE>
 
corporation, partnership, joint venture, trust or other enterprise to the
fullest extent permissible under Delaware law and to the extent approved by the
Board of Directors from time to time.

     Section 3.  Expenses as a Witness.  To the extent that any Director,
                 ---------------------                                   
officer, employee or agent of the Corporation, or any person who is serving at
the request of the Corporation as an officer, director, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise is,
by reason of such position or position with such other entity, a witness in any
action, suit or proceeding, he or she shall be indemnified against all costs and
expenses actually and reasonably incurred by him or her or on his or her behalf
in connection therewith.

     Section 4.  Insurance.  The Corporation may maintain insurance, at its
                 ---------                                                 
expense, to protect itself and any Director, officer, employee or agent of the
Corporation or another corporation, partnership, joint venture, trust or other
enterprise against any such expenses, liability or loss, whether or not the
Corporation would have the power to indemnify such person against such expense,
liability or loss under Delaware law.

     Section 5.  Indemnity Agreements.  The Corporation may enter into
                 --------------------                                 
agreements with any Director, officer, employee or agent of the Corporation and
with any person who is or was serving at the request of the Corporation as an
officer, director, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise, providing for indemnification to the fullest
extent permissible under Delaware law.

     Section 6.  Separability.  Each and every paragraph, sentence, term and
                 ------------                                               
provision of this Article IX is separate and distinct, so that if any paragraph,
sentence, term or provision hereof shall be held to be invalid or unenforceable
for any reason, such invalidity or unenforceability shall not affect the
validity or unenforceability of any other paragraph, sentence, term or provision
hereof.  To the extent required, any paragraph, sentence, term or provision of
this Article IX may be modified by a court of competent jurisdiction to preserve
its validity and to provide the claimant with, subject to the limitations set
forth in this Article IX and any agreement between the Corporation and claimant,
the broadest possible indemnification permitted under applicable law.

     Section 7.  Contract Right.  Each of the rights conferred by Sections 1 and
                 --------------                                                 
3 of this Article IX shall be a contract right, and any repeal or amendment of
the provisions of this Article shall not adversely affect any right hereunder of
any person existing at the time of such repeal or amendment with respect to any
act or omission occurring prior to the time of such repeal or amendment, and,
further, shall not apply to any proceeding, irrespective of when the proceeding
is initiated, arising from the service of such person prior to such repeal or
amendment.  Further, the mandatory indemnification and expense advancement for
officers of the Corporation and such other persons who serve at the request of
the Corporation as a director or officer of another corporation, partnership,
joint venture, trust or other enterprise set forth in Section 1 of this Article
IX shall apply solely with respect to acts or omissions of such officers and
directors occurring on or after August 6, 1998.

     Section 8.  Nonexclusivity.  The rights conferred in this Article shall not
                 --------------                                                 
be exclusive of any other rights that any person may have or hereafter acquire
under any statute, bylaw, agreement, vote of stockholders or disinterested
directors or otherwise.


                                 ARTICLE X
                                 AMENDMENTS

Certificate of Incorporation, at any regular meeting of the stockholders or
Board of Directors, or at any special meeting of the stockholders or of the
Board of Directors if notice of such alteration, amendment, repeal or adoption
of new Bylaws be contained in the notice of such special meeting. If the power
to adopt, amend or repeal Bylaws is conferred upon the Board of Directors by the
Certificate of Incorporation, it shall not divest or limit the power of the
stockholders to adopt, amend or repeal these Bylaws.


                                  ARTICLE XI
                                 MISCELLANEOUS

     Section 1.  Fiscal Year.  The initial taxable year of the Corporation shall

commence on the date the Certificate of Incorporation is filed, and end on such
date as the Board of Directors may determine, in accordance with all applicable
provisions of the Internal Revenue Code of 1986, as amended.

     Section 2.  Seal.  The corporate seal shall have inscribed thereon the name
                 ----
