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

     2.1  PLACE OF MEETINGS
          -----------------
================================================================================
     Meetings of stockholders may be held at any place,        [Amended
either within or outside of the State of Delaware,             5-29-97]
designated for such purpose by the board of directors.
In the absence of any such designation, meetings of 
stockholders shall be held at the registered office of 
the corporation in Delaware.
================================================================================

     2.2  ANNUAL MEETING
          --------------
     An annual meeting of stockholders shall be held each         [Amended
year on a date and at a time designated by the board of            5-29-97]
directors. In the absence of any such designation by the 
board of directors, the chairman of the board may make 
such designation. At each annual meeting, directors shall 
be elected and any other proper business may be transacted.
================================================================================

     2.3  SPECIAL MEETING
          ---------------

     A special meeting of stockholders may be called at any time by the board of
directors, the chairman of the board, or the president. Except as otherwise
expressly provided in these by-laws, no other person or persons may call a
special meeting of stockholders. No business may be conducted at a special
meeting of stockholders other than the business brought before the meeting by
the board of directors, the chairman of the board, or the president.

 
     2.4  NOTICE OF MEETINGS OF STOCKHOLDERS
          ----------------------------------

     Written notice of a meeting of stockholders 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. The notice shall specify 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. If mailed, notice is given
when deposited in the United States mail, postage prepaid, directed to the
stockholder at such stockholder's address as it appears on the records of the
corporation. An affidavit of the secretary or an assistant secretary or of the
transfer agent of the corporation that the notice has been given shall, in the
absence of fraud, be prima facie evidence of the facts stated therein.

     2.5  ADJOURNED MEETING
          -----------------

     When a meeting of stockholders is adjourned to another time or place,
unless these by-laws otherwise require, notice need not be given of the
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.

     2.6  QUORUM
          ------

     A majority of the shares entitled to vote thereat, present in person or
represented by proxy, shall constitute a quorum at a meeting of stockholders.
Where a separate vote by a class or classes is required, a majority of the
outstanding shares of such class or classes, present in person or represented by
proxy, shall constitute a quorum entitled to take action with respect to that
vote on that matter. If, however, a quorum is not present or represented at any
meeting of stockholders, then either (i) the chairman of the meeting or (ii) the
stockholders entitled to vote thereat, present in person or represented by
proxy, shall have the power to adjourn the meeting from time to time, without
notice other than announcement at the meeting except as otherwise provided in
Section 2.5, until a quorum is present in person or represented by proxy.

     2.7  CONDUCT OF BUSINESS
          -------------------

     Subject to any applicable requirements of the General Corporation Law of
the State of Delaware, the chairman of any meeting of stockholders shall
determine the order of business and the procedure at the meeting.

     2.8  VOTE REQUIRED
          -------------

     When a quorum is present at a meeting of stockholders, the affirmative vote
of the majority of shares present in person or represented by proxy at the
meeting and entitled to vote on the subject matter of the vote shall be the act
of the stockholders in all matters other than the election of directors. When a
quorum is present at a meeting of stockholders, directors shall be elected by a
plurality of the votes of the shares present in person or represented by proxy
at the meeting and entitled to vote on the election of directors. Subject to the
quorum requirements of Section 2.5, where a separate vote by a class or classes
is required, the affirmative vote of the majority of shares of

                                       2

 
such class or classes present in person or represented by proxy at the meeting
shall be the act of such class.


                                       3

 
     2.9  STOCKHOLDER ACTION BY WRITTEN CONSENT WITHOUT A MEETING
================================================================================
     Unless otherwise provided in the certificate of           [Amended
incorporation of the corporation, any action required          5-29-97]
by the General Corporation Law of the State of 
Delaware to be taken at any annual or special meeting 
of stockholders, or any action that may 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 or consents 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 and
shall be delivered to the corporation by delivery to 
its registered office in Delaware, to its principal 
place of business, or to an officer or agent of the
corporation having custody of the book in which 
proceedings of meetings of stockholders are recorded. 
Prompt notice of the taking of such action without a
meeting by less than unanimous written consent shall 
be given to those stockholders who have not consented 
in writing.
================================================================================

     2.10 PROXIES
          -------

     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 or her 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 proxy may
be made irrevocable regardless of whether the interest with which it is coupled
is an interest in the stock itself or an interest in the corporation generally.

     2.11 RECORD DATE
          -----------

     In a manner consistent with the provisions of Section 213 of the General
Corporation Law of the State of Delaware, the board of directors may fix a
record date for any of the purposes specified in such Section 213. If no record
date is fixed by the board of directors for any of such purposes, then the
record date for such purpose shall be as provided in such Section 213.

     2.12 WAIVER OF NOTICE
          ----------------

     Whenever notice is required to be given under any provision of the General
Corporation Law of the State of Delaware, the certificate of incorporation of
the corporation, or these by-laws, a written waiver thereof, signed by the
person entitled to notice, whether before or after the time stated therein,
shall be deemed equivalent to notice. Attendance of a stockholder at a meeting
of stockholders shall constitute a waiver of notice of such meeting, except when
the stockholder attends a meeting of stockholders 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
stockholders need be specified in any written waiver of notice unless so
required by the certificate of incorporation of the corporation or these 
by-laws.

     2.13 ADVANCE NOTICE OF STOCKHOLDER NOMINEES
================================================================================
     Nominations of persons for election to the board of      [Amended
directors may be made at a meeting of stockholders either     5-29-97]
by or at the direction of the board of directors or by any 
stockholder entitled to vote on the election of directors 
at the meeting who has complied with the notice procedures 
set forth in this Section. A stockholder who desires to
nominate a person for election to the board of directors at 
a meeting of stockholders must give timely written notice 
of the proposed nomination to the secretary of the 
corporation. To be timely, a stockholder's notice must be
received at the principal executive offices of the 
corporation not less than 120 calendar days in advance of 
the date of the proxy statement of the corporation released 
to stockholders in connection with the previous year's 
annual meeting of stockholders; provided, however, that in 
the event that no annual meeting of stockholders was held in 
the previous year or that the date of the forthcoming annual 
meeting of stockholders has been changed by more than 30 days 
from the date contemplated at the time of the previous year's 
proxy statement or that the forthcoming meeting is not an 
annual meeting of 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 earlier of (a) the 
day on which notice of the date of the forthcoming meeting 
was mailed or given to stockholders or (b) the day on which 
public disclosure of the date of the forthcoming meeting was 
made. Such stockholder's notice to the secretary shall set 
forth (a) as to each person, if any, whom the stockholder 
proposes to nominate for election or re-election as a 
director (i) the name, age, business address, and residence 
address of such person, (ii) the principal occupation or 
employment of such person, (iii) the class and number of 
shares of capital stock of the corporation which are 
beneficially owned by such person, (iv) any other 
information relating to such person that is required by 
law or regulation to be disclosed in solicitations of 
proxies for the election of directors, and (v) such 
person's written consent to being named as a nominee and 
to serve as a director if elected and (b) as to the 
stockholder giving the notice (i) the name and address, 
as they appear on the books of the corporation, of such
stockholder, (ii) the class and number of shares of 
capital stock of the corporation which are beneficially 
owned by such stockholder, (iii) a description of all 
arrangements or understandings between such stockholder 
and each nominee and any other person or persons 
(naming such person or persons) relating to the 
nomination proposed to be made by such stockholder, and 
(iv) any other information required by law or regulation 
to be provided by a stockholder intending to nominate a 
person for election as a director of the corporation. At
the request of the board of directors, any person 
nominated by the board of directors for election as a 
director shall furnish to the secretary of the 
corporation the information required to be set forth in 
a stockholder's notice of proposed nomination which 
pertains to the nominee. No person shall be eligible for 
election as a director of the corporation unless nominated 
in compliance with the procedures set forth in this 
Section. The chairman of the meeting shall, if the facts 
warrant, determine and declare at the meeting that a
nomination was not made in compliance with the procedures 
prescribed by this Section; and if such chairman shall so 
determine, then he or she shall so declare at the meeting, 
and the defective nomination shall be disregarded.

     2.14 ADVANCE NOTICE OF STOCKHOLDER BUSINESS
================================================================================
     At an annual meeting of stockholders, only such           [Amended
business shall be conducted as shall have been properly        5-29-97]
brought before the meeting. To be properly brought before
an annual meeting of stockholders, business must be (a) 
as specified in the notice of the meeting (or any 
supplement thereto) given by or at the direction of the 
board of directors, (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 a stockholder. Business to be brought before 
an annual meeting by a stockholder shall not be considered 
properly brought if the stockholder has not given timely 
notice thereof in writing to the secretary of the 
corporation. To be timely, a stockholder's notice of 
business to be brought before an annual meeting must be 
received at the principal executive offices of the 
corporation not less than 120 calendar days in advance
of the date of the proxy statement of the corporation 
released to stockholders in connection with the previous 
year's annual meeting of stockholders; provided, however, 
that in the event that no annual meeting of stockholders 
was held in the previous year or that the date of the 
forthcoming annual meeting of stockholders has been changed 
by more than 30 days from the date contemplated at the 
time of the previous year's proxy statement, notice by the 
stockholder to be timely must be so received not later than 
the close of business on the tenth day following the earlier 
of (a) the day on which notice of the date of the forthcoming 
annual meeting was mailed or given to stockholders or (b) 
the date on which public disclosure of the date of the 
forthcoming annual meeting was made. Such stockholder's 
notice to the secretary shall set forth as to each matter 
the stockholder proposes to bring before the annual meeting 
(i) a brief description of the business desired to be 
brought before the annual meeting and the reasons for 
conducting such business at the annual meeting, (ii) the name
and address of the stockholder proposing such business, 
(iii) the class and number of shares of capital stock 
of the corporation which are beneficially owned by the 
stockholder, (iv) any material interest of the stockholder 
in such business, and (v) any other information that is 
required by law or regulation to be provided by the 
stockholder in his capacity as a proponent of a stockholder
proposal. Notwithstanding anything in these by-laws to the
 contrary, no business shall be conducted at any annual 
meeting of stockholders except in compliance with the 
procedures set forth in this Section. The chairman of the 
annual meeting of stockholders shall, if the facts warrant, 
determine and declare at the meeting that business was not 
properly brought before the meeting in compliance with the 
provisions of this Section; and, if such chairman shall so
determine, then he or she shall so declare at the meeting, 
and any such business not properly brought before the meeting 
shall not be transacted.
================================================================================

     2.15 REGISTERED STOCKHOLDERS
          -----------------------

          The corporation shall be entitled to recognize a person registered as
the owner of shares on the stock ledger of the corporation as the sole person
entitled to receive dividends on such shares and to vote such shares and shall
not be obligated to recognize for any purpose any equitable or other interest in
or claim to such shares on the part of another person, whether or not the
corporation has express or other notice thereof, except as otherwise provided in
the General Corporation Law of the State of Delaware.

                                   ---------

     3.1  POWERS
          ------

     Subject to the provisions of the General Corporation Law of the State of
Delaware and to any limitations contained in the certificate of incorporation of
the corporation or these by-laws, the business and affairs of the corporation
shall be managed and all corporate powers shall be exercised by or under the
direction of the board of directors.

     3.2  NUMBER OF DIRECTORS
================================================================================
     The board of directors shall consist of not fewer       [Amended
than five (5) members and not more than nine (9) members,    5-29-97]
the exact number within such range to be fixed from time 
to time by a resolution adopted by the board of directors. 
Until otherwise fixed by such a resolution, the board of 
directors shall consist of seven (7) members. No reduction 
in the authorized number of members of the board of directors 
shall have the effect of removing any director before that
director's term of office expires.
===============================================================================
 
     3.3  ELECTION, QUALIFICATION, AND TERM OF OFFICE OF DIRECTORS
================================================================================
     Except as provided in Section 3.4 of these by-laws,     [Amended
directors shall be elected at each annual meeting of         5-29-97]
stockholders. Directors need not be stockholders unless 
so required by the certificate of incorporation of the
corporation. Each director, including a director elected 
to fill a vacancy, shall hold office until his or her 
successor is elected and qualified or until his or her 
earlier resignation or removal.
================================================================================
 
     3.4  RESIGNATION AND VACANCIES
================================================================================
     Any director may resign at any time upon written        [Amended
notice sent or delivered to the secretary of the             5-29-97]
corporation. When a director so resigns and the
resignation is effective at a future date, a majority 
of the directors then in office, including those who 
have so resigned, shall have the power to fill such
vacancy with the vote thereon to take effect when such 
resignation becomes effective.
===============================================================================

     Unless otherwise provided in the certificate of incorporation of the
corporation:

          (i) Vacancies and newly created directorships resulting from any
increase in the authorized number of directors elected by all of the
stockholders having the right to vote as a single class may be filled by a
majority of the directors then in office, although less than a quorum, or by a
sole remaining director.

          (ii) Whenever the holders of any class or classes of stock or series

elected.

     If at any time, by reason of death or resignation or other cause, the
corporation has no directors in office, then any officer or any stockholder or
an executor, administrator, trustee, or guardian of a stockholder, or other
fiduciary entrusted with similar responsibility for the person or estate of a
stockholder, may call a special meeting of stockholders to elect directors or
may apply to the Delaware Court of Chancery for a decree summarily ordering an
election as provided in Section 211 of the General Corporation Law of the State
of Delaware.

     3.5  PLACE OF MEETINGS; MEETINGS BY TELEPHONE
          ----------------------------------------

     The board of directors of the corporation may hold meetings, both regular
and special, either within or outside of the State of Delaware.

     Unless otherwise restricted by the certificate of incorporation of the
corporation, 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 such 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.

     3.6  REGULAR MEETINGS
          ----------------

     Regular meetings of the board of directors may be held without notice at
such time and at such place as the board of directors from time to time shall
determine.

     3.7  SPECIAL MEETINGS; NOTICE
          ------------------------

     Special meetings of the board of directors for any purpose or purposes may
be called at any time by the chairman of the board, the president, or any two
(2) directors.  Notice of the time and place of special meetings of the board of
directors shall be delivered personally or by telephone or by facsimile
transmission to each director or sent by first-class mail, overnight express
delivery, or telegram, charges prepaid, addressed to each director at that
director's address as it is shown on the records of the corporation.  If the
notice is mailed, it shall be deposited in the United States mail at least four
(4) days before the time of the holding of the meeting.  If the notice is
delivered personally or by telephone, facsimile transmission, or telegram, it
shall be delivered personally or by telephone or facsimile equipment or to the
telegraph company at least forty-eight (48) hours before the time of the holding
of the meeting.  If the notice is delivered by facsimile transmission, the
person giving the notice shall use reasonable efforts to confirm the receipt of
such transmission.  Any oral notice delivered personally or by telephone may be
communicated either to the director or to a person at the office of the director
who the person giving the notice has reason to believe will promptly communicate
such notice to the director.  The notice need not specify the purpose of the
meeting.

     3.8  QUORUM
          ------

     At all meetings of the board of directors, a majority of the authorized
number of directors shall constitute a quorum for the transaction of business;
and the vote of a majority of the directors present at any meeting at which a

                                       8

 
quorum is present shall be the act of the board of directors, except as
otherwise specifically provided by the certificate of incorporation of the
corporation.  If a quorum is not present at any meeting of the board of
directors, then the directors present thereat may adjourn the meeting from time
to time, without notice other than announcement at the meeting, until a quorum
is present.  A meeting at which a quorum initially is present may continue to
transact business notwithstanding the withdrawal of directors if any action
taken is approved by at least a majority of the required quorum for that
meeting.

     3.9 WAIVER OF NOTICE
         ----------------

     Whenever notice is required to be given under any provision of the General
Corporation Law of the State of Delaware, the certificate of incorporation of
the corporation, or these by-laws, a written waiver thereof, signed by the
person entitled to notice, whether before or after the time stated therein,
shall be deemed equivalent to notice.  Attendance of a director at a meeting of
the board of directors shall constitute a waiver of notice of such meeting,
except when the director attends a meeting of the board of directors 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 board of directors, or of a committee of
directors, need be specified in any written waiver of notice unless so required
by the certificate of incorporation of the corporation or these by-laws.

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

     Unless otherwise restricted by the certificate of incorporation of the

consent thereto in writing, and the writing or writings are filed with the
minutes of proceedings of the board of directors or committee, as the case may
be.

     3.11 FEES AND COMPENSATION OF DIRECTORS

     Unless otherwise restricted by the certificate of incorporation of the
corporation, the board of directors shall have the authority to fix the
compensation of directors.

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

     The corporation may lend money to, or guarantee any obligation of, or
otherwise assist any officer or other employee of the corporation or any
subsidiary, including any officer or employee who is a director of the
corporation or any subsidiary, whenever, in the judgment of the directors, such
loan, guaranty, or assistance reasonably may be expected to benefit the
corporation.  The loan, guaranty, or other assistance may be with or without
interest and may be unsecured or secured in such manner as the board of
directors shall approve, including, without limitation, a pledge of shares of
stock of the corporation.  Nothing contained in this Section shall be deemed to
deny, limit, or restrict the powers of guaranty or warranty of the corporation
at common law or under any statute.

 whole board, designate one or more committees, with each committee to consist

 management of the business and affairs of the corporation and may authorize the
 seal of the corporation to be affixed to all papers that may require it; but no
 such committee shall have the power or authority to (i) amend the certificate
 of incorporation (except that a committee may, to the extent authorized in the
 resolution or resolutions providing for the issuance of shares of stock adopted
 by the board of directors as provided in Section 151(a) of the General
 Corporation Law of the State of Delaware, fix the designations and 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 or fix the number of shares of any series of stock or authorize the
 increase or decrease of the shares of any series), (ii) adopt an agreement of
 merger or consolidation under Sections 251 or 252 of the General Corporation
 Law of the State of Delaware, (iii) recommend to the stockholders the sale,
 lease, or exchange of all or substantially all of the corporation's property

 or a revocation of a dissolution, or (v) amend the by-laws of the corporation;
 and, unless the board resolution establishing the committee, these by-laws, or
 the certificate of incorporation of the corporation expressly so provides, no
 such committee shall have the power or authority to declare a dividend, to
 authorize the issuance of stock, or to adopt a certificate of ownership and
 merger pursuant to Section 253 of the General Corporation Law of the State of
 Delaware.

meetings and notice), Section 3.8 (quorum), Section 3.9 (waiver of notice), and
Section 3.10 (action without a meeting) of these by-laws, with such changes in
the context of those by-laws as are necessary to substitute the committee and
its members for the board of directors and its members; provided, however, that
the time of regular meetings of committees may be determined either by
resolution of the board of directors or by resolution of the committee, that
special meetings of committees also may be called by resolution of the board of

                                      11

 
directors and by the chairman of the committee, and that notice of special
meetings of committees also shall be given to all alternate members of the
committee, who shall have the right to attend all meetings of the committee.
The board of directors may appoint the chairman of any committee and may adopt
rules for the governance and procedures of any committee not inconsistent with
the provisions of these by-laws.  If the board of directors does not appoint a
chairman of any committee or does not adopt rules for the governance and
procedures of any committee, then the members of such committee may do so.

corporation.  An officer's resignation shall be effective when the notice is
delivered unless the notice specifies a later effective date.  If an officer's
resignation is made effective at a later date and the corporation accepts the
future effective date, then the board of directors may fill the pending vacancy
before such effective date if the board of directors provides that the successor
shall not take office until such effective date.  An officer's resignation shall
not affect the corporation's contract rights, if any, with the officer.

          5.4  REMOVAL
               -------

other officer or agent of the corporation or is required by law to be done
otherwise. The chairman of the board may vote and exercise all other rights with

its chief executive officer and shall have such other powers and perform such
other duties as the chairman of the board or the board of directors may assign
to him or her from time to time.  Unless otherwise provided by the board of
directors, whenever the chairman of the board is unable to serve or the position
of chairman of the board is vacant, the president also shall perform all duties
and exercise all powers of the chairman of the board.

          5.7  VICE PRESIDENT
               --------------

person against such liability under the General Corporation Law of the State of
Delaware.

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

          The shares of the corporation shall be represented by certificates;
provided, that the board of directors of the corporation may provide by
resolution or resolutions that some or all of any or all classes or series of
the stock of the corporation shall be uncertificated shares.  Any such
resolution shall not apply to shares represented by a certificate until such
certificate is surrendered to the corporation.  Notwithstanding the adoption of
such a resolution by the board of directors, every holder of stock represented
by certificates and upon request every holder of uncertificated shares shall be
entitled to have a certificate signed by or in the name of the corporation by
the chairman of the board, the president, or a vice-president and by the chief
financial officer, an assistant treasurer, the secretary, or an assistant
secretary representing the number of shares registered in certificate form.  Any
or all of the signatures on the certificate may be a facsimile.  In case any
officer, transfer agent, or registrar who has signed or whose facsimile
signature has been placed upon a certificate has ceased to be such officer,
transfer agent, or registrar before such certificate is issued, such certificate
may be issued by the corporation with the same effect as if the person were such

face or back of the certificate that the corporation shall issue to represent
such class or series of stock; provided, however, that, except as otherwise
provided in Section 202 of the General Corporation Law of the State of Delaware,
in lieu of the foregoing requirements there may be set forth on the face or back
of the certificate which the corporation shall issue to represent such class or
series of stock a statement that the corporation will furnish without charge to
each stockholder who so requests the powers, designations, preferences, and
relative, participating, optional, or other special rights of each class of
stock or series thereof and the qualifications, limitations, or restrictions of
such preferences and/or rights.

          7.3  LOST CERTIFICATES
               -----------------

          All certificates for shares of stock surrendered to the corporation
for transfer shall be cancelled, and no new certificates for shares of stock
shall be issued to replace a previously issued certificate unless the latter is
surrendered to the corporation and canceled at the same time. However, the
corporation may issue a new certificate of stock or uncertificated shares in
place of any certificate theretofore issued by it alleged to have been lost,
stolen, or destroyed; and the corporation may require the owner of the lost,
stolen, or destroyed certificate, or such owner's legal representative, to give
the corporation a bond sufficient to indemnify the corporation against any claim
that may be made against the corporation on account of the alleged loss, theft,
or destruction of any such certificate or the issuance of such new certificate
or uncertificated shares.

          7.4  TRANSFER OF SHARES
               ------------------

          Transfer of shares of stock of the corporation shall be made only on
the stock transfer books of the corporation by the holder of record thereof or
by his or her legal representative, who shall furnish proper evidence of
authority to effect such transfer, or by his or her attorney thereunto duly
authorized by power-of-attorney duly executed and filed with the secretary or
with a transfer agent appointed pursuant to these by-laws, and only upon the
surrender for cancellation of the certificate or certificates for such shares of
stock properly endorsed and the payment of all applicable transfer taxes. Except
as otherwise provided in these by-laws or by the General Corporation Law of the
State of Delaware, the person in whose name shares of stock stand on the books
of the corporation shall be deemed by the corporation to be the owner of such
shares of stock for all purposes. The board of directors from time to time may
make such additional rules and regulations, consistent with these by-laws and
the General Corporation Law of the State of Delaware, as it may deem expedient
concerning the issue, transfer, and registration of the shares of the
corporation. The board of directors from time to time may appoint one or more
transfer agents and one or more registrars for any class of stock of the
corporation.

                     Amendments of Revised By-Laws Adopted
                        By Stockholders on May 29, 1997
                        -------------------------------


            "3.2  NUMBER OF DIRECTORS
                  -------------------

            The board of directors shall consist of not fewer than five (5)
members and not more than thirteen (13) members, the exact number of authorized
directors within such range to be fixed from time to time by a resolution of the
board of directors adopted by the affirmative vote of at least a majority of the
total number of authorized directors most recently fixed by the board of
directors."

            "3.3  CLASSES, ELECTION, AND TERM OF OFFICE OF DIRECTORS
                  --------------------------------------------------

            The directors shall be divided into three classes for the purpose of
determining their terms of office. Each such class shall consist, as nearly as
possible, of one-third of the total number of directors fixed by the board of
directors. At the annual meeting of stockholders held in 1997, one class of
directors (designated as Class I) shall be elected for a term expiring at the
annual meeting of stockholders held in 1998, one class of directors (designated
as Class II) shall be elected for a term expiring at the annual meeting of
stockholders held in 1999, and one class of directors (designated as Class III)
shall be elected for a term expiring at the annual meeting of stockholders held
in 2000. At each succeeding annual meeting of stockholders, beginning in 1998,
successors to the class of directors whose term expires at that annual meeting
shall be elected for a term expiring at the annual meeting of stockholders held
in the third year following the year of their election. If the number of
directors is changed, then any increase or decrease in such number shall be
apportioned by the board of directors among the classes of directors so as to
maintain as nearly as possible an equal number of directors in each class. No
reduction in the authorized number of members of the board of directors shall
have the effect of removing any director from office before that director's term
of office expires. Each director, including a director elected to fill a vacancy
or a newly created directorship, shall hold office until the next election of
the class of directors to which such director belongs and until his or her
successor is elected and qualified or until his or her earlier death,
resignation, or removal from office for cause."

            "3.4  RESIGNATION AND VACANCIES
                  -------------------------

            Any director may resign at any time upon written notice to the
corporation. When a director so resigns

                                      18

 
and the resignation is effective at a future date, a majority of the directors
then in office, including those who have so resigned, shall have the power to
fill such vacancy with the vote thereon to take effect when such resignation
becomes effective. Vacancies on the board of directors and newly created
directorships resulting from an increase in the authorized number of members of
the board of directors may be filled only by a majority of the directors then in
office, although less than a quorum, or by a sole remaining director."

            "3.13 REMOVAL OF DIRECTORS
                  --------------------

            Any director or the entire board of 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 seventy-five (75%) of the voting power of all outstanding
shares of capital stock then entitled to vote in an election of directors,
voting as a single class."

          2.1  PLACE OF MEETINGS
               -----------------

                   Meetings of stockholders may be held at any place, either
within or outside of the State of Delaware, designated for such purpose by or at
the direction of the board of directors. In the absence of any such designation,
meetings of stockholders shall be held at the registered office of the
corporation in Delaware.


          2.2  ANNUAL MEETING
               --------------

                   An annual meeting of stockholders shall be held each year on
a date and at a time designated by or at the direction of the board of
directors. At each annual meeting, directors shall be elected and any other
proper business may be transacted.


          2.9  STOCKHOLDER ACTION BY WRITTEN CONSENT WITHOUT A MEETING
               -------------------------------------------------------

                   Unless otherwise provided in the certificate of incorporation
of the corporation, any action required by the General Corporation Law of the
State of Delaware to be taken at any annual or special meeting of stockholders,
or any action that may 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 or consents 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
and shall be delivered to the corporation by delivery to its registered office
in Delaware, to its principal place of business, or to an officer or agent of
the corporation having custody of the book in which proceedings of meetings of
stockholders are recorded. Prompt notice of the taking of such action without a
meeting by less than unanimous written consent shall be given in accordance with
the requirements of the General Corporation Law of the State of Delaware.


          2.13 ADVANCE NOTICE OF STOCKHOLDER NOMINEES
               --------------------------------------

                   Nominations of persons for election to the board of directors
may be made at a meeting of stockholders either by or at the direction of the
board of directors

                                      20

 
or by any stockholder of record entitled to vote in the election of directors at
such meeting who has complied with the notice procedures set forth in this
Section 2.13. A stockholder who desires to nominate a person for election to the
board of directors at a meeting of stockholders and who is eligible to make such
nomination must give timely written notice of the proposed nomination to the
secretary of the corporation. To be timely, a stockholder's notice given
pursuant to this Section 2.13 must be received at the principal executive office
of the corporation not less than one hundred twenty (120) calendar days in
advance of the date which is one year later than the date of the proxy statement
of the corporation released to stockholders in connection with the previous
year's annual meeting of stockholders; provided, however, that if no annual
meeting of stockholders was held in the previous year or if the date of the
forthcoming annual meeting of stockholders has been changed by more than thirty
(30) calendar days from the date contemplated at the time of the previous year's
proxy statement or if the forthcoming meeting is not an annual meeting of
stockholders, then to be timely such stockholder's notice must be so received
not later than the close of business on the tenth day following the earlier of
(a) the day on which notice of the date of the forthcoming meeting was mailed or
given to stockholders by or on behalf of the corporation or (b) the day on which
public disclosure of the date of the forthcoming meeting was made by or on
behalf of the corporation. Such stockholder's notice to the secretary of the
corporation 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 such person, (ii) the principal
occupation or employment of such person, (iii) the class and number of shares of
capital stock of the corporation which then are beneficially owned by such
person, (iv) any other information relating to such person that is required by
law or regulation to be disclosed in solicitations of proxies for the election
of directors of the corporation, and (v) such person's written consent to being
named as a nominee for election as a director and to serve as a director if
elected and (b) as to the stockholder giving the notice (i) the name and
address, as they appear in the stock records of the corporation, of such
stockholder, (ii) the class and number of shares of capital stock of the
corporation which then are beneficially owned by such stockholder, (iii) a
description of all arrangements or understandings between such stockholder and
each nominee for election as a director and any other person or persons (naming
such person or persons) relating to the nomination proposed to be made by such
stockholder, and (iv) any other information required by law or regulation to be
provided by a stockholder intending to nominate a person for election as a
director of the corporation. At the request of the board of directors, 

                                      21

 
any person nominated by or at the direction of the board of directors for
election as a director of the corporation shall furnish to the secretary of the
corporation the information concerning such nominee which is required to be set
forth in a stockholder's notice of a proposed nomination. No person shall be
eligible for election as a director of the corporation unless nominated in
compliance with the procedures set forth in this Section 2.13. The chairman of a
meeting of stockholders shall refuse to accept the nomination of any person not
made in compliance with the procedures set forth in this Section 2.13, and such
defective nomination shall be disregarded.

                                      22

 
          2.14  ADVANCE NOTICE OF STOCKHOLDER BUSINESS
                --------------------------------------

                   At an annual meeting of stockholders, only such business
shall be transacted as shall have been properly brought before the meeting. To
be properly brought before an annual meeting of stockholders, business must be
(a) as specified in the notice of the meeting (or any supplement thereto) given
by or at the direction of the board of directors, (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 a stockholder. Business to be
brought before an annual meeting by a stockholder shall not be considered
properly brought if the stockholder has not given timely written notice thereof
to the secretary of the corporation. To be timely, a stockholder's notice of
business to be brought before an annual meeting must be received at the
principal executive office of the corporation not less than one hundred twenty
(120) calendar days in advance of the date which is one year later than the date
of the proxy statement of the corporation released to stockholders in connection
with the previous year's annual meeting of stockholders; provided, however, that
if no annual meeting of stockholders was held in the previous year or if the
date of the forthcoming annual meeting of stockholders has been changed by more
than thirty (30) calendar days from the date contemplated at the time of the
previous year's proxy statement, then to be timely such stockholder's notice
must be so received not later than the close of business on the tenth day
following the earlier of (a) the day on which notice of the date of the
forthcoming annual meeting was mailed or given to stockholders by or on behalf
of the corporation or (b) the day on which public disclosure of the date of the
forthcoming annual meeting was made by or on behalf of the corporation. Such
stockholder's notice to the secretary of the corporation shall set forth as to
each matter the stockholder proposes to bring before the annual meeting (i) a
brief description of the business desired to be brought before the annual
meeting and the reasons for transacting such business at the annual meeting,
(ii) the name and address of the stockholder proposing such business, (iii) the
class and number of shares of capital stock of the corporation which then are
beneficially owned by such stockholder, (iv) any material interest of such
stockholder in such business, and (v) any other information required by law or
regulation to be provided by such stockholder in such stockholder's capacity as
a proponent of a stockholder proposal. Notwithstanding anything in these by-laws
to the contrary, no business shall be conducted at any annual meeting of
stockholders except in compliance with the procedures set forth in this Section
2.14. The chairman of the annual meeting of stockholders shall, if the facts
warrant, determine at the meeting that business was not properly brought before
the meeting in compliance with the provisions of this Section 2.14; and, if such
chairman shall so determine, 

                                      23

 
then he or she shall so declare at the meeting, and any such business not
properly brought before the meeting shall not be transacted.


          4.1  COMMITTEES OF DIRECTORS
               -----------------------

                   The board of directors may designate one or more committees,
with each such 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. In the absence or disqualification of a
member of a committee, the member or members thereof present at any meeting and
not disqualified from voting, whether or not such member or members constitute a
quorum, may unanimously appoint another member of the board of directors to act
at the meeting in the place of any such absent or disqualified member. Any such
committee, to the extent provided in the resolution of the board of directors or
in these by-laws, 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 that may require it; but no such committee shall have the power or
authority of the board of directors in reference to the following matters: (i)
approving or adopting, or recommending to the stockholders, any action or matter
expressly required by the General Corporation Law of the State of Delaware to be
submitted to stockholders for approval or (ii) adopting, amending, or repealing
any by-law of the corporation.
