                        MICROCHIP TECHNOLOGY INCORPORATED
                         As Amended Through May 19, 1997

                                    ARTICLE I
                                CORPORATE OFFICES

         1.1 Registered  Office.  The registered office of the corporation shall
be in the City of Dover,  County  of Kent,  State of  Delaware.  The name of the
registered  agent of the corporation at such location is The  Corporation  Trust
Company.

         1.2 Other Offices.  The corporation may also have offices at such other
places both  within and without the State of Delaware as the board of  directors
may from time to time determine or the business of the corporation may require.


                                   ARTICLE II
                                  STOCKHOLDERS

         2.1 Place of Meetings.  Meetings of  stockholders  shall be held at any
place,  within or  outside  the State of  Delaware,  designated  by the board of
directors. In the absence of any such designation,  stockholders' meetings shall
be held at the registered office of the corporation.

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

         To be properly  brought before an annual  meeting  business must be (a)
specified in the notice of 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.  For  business  to be
properly  brought  before the meeting by a  stockholder,  the  secretary  of the
corporation  must have received  notice in writing from the stockholder not less
than  thirty  (30) days nor more than  sixty  (60)  days  prior to the  meeting;
provided,  however,  that if less  than  thirty-five  (35)  days'  notice of the
meeting is given to  stockholders,  such notice shall have been  received by the
secretary  not  later  than the  close of  business  on the  seventh  (7th)  day
following the day on which the notice of meeting was mailed. Such written 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,  (ii)
the  name  and  address,  as they  appear  on the  corporation's  books,  of the
stockholder proposing such business,  (iii) the number of shares of stock of the
corporation  beneficially  owned by such  stockholder,  and  (iv)  any  material
interest of such stockholder in such business.  Notwithstanding any provision in
the bylaws to the

contrary,  no  business  shall be  conducted  at an  annual  meeting  except  in
accordance with the procedures set forth in this Section 2.2.

         2.3  Special  Meeting.  A special  meeting of the  stockholders  may be
called at any time by the board of  directors or by the chairman of the board or
by one or more stockholders  owning in the aggregate not less than fifty percent
(50%) of the entire capital stock of the corporation  issued and outstanding and
entitled vote.

         If a special  meeting is called by any person or persons other than the
board of directors, the request shall be in writing, specifying the time of such
meeting and the general nature of the business  proposed to be  transacted,  and
shall be delivered  personally or sent by registered  mail or by  telegraphic or
other facsimile transmission to the chairman of the board, the president,  chief
executive  officer or the  secretary  of the  corporation.  No  business  may be
transacted at such special meeting otherwise than specified in such notice.  The
officer  receiving  the request  shall cause notice to be promptly  given to the
stockholders entitled to vote, in accordance with the provisions of Sections 2.4
and 2.5,  that a meeting  will be held at the time  requested  by the  person or
persons who called the  meeting,  not less than  thirty-five  (35) nor more than
sixty (60) days after the  receipt  of the  request.  If the notice is not given
within twenty (20) days after the receipt of the request,  the person or persons
requesting the meeting may give the notice.  Nothing contained in this paragraph
of this Section 2.3 shall be construed as  limiting,  fixing,  or affecting  the
time when a meeting of  stockholders  called by action of the board of directors
may be held.

         2.4  Notice of  Stockholders  Meetings.  All  notices  of  meetings  of
stockholders  shall  be in  writing  and  shall  be sent or  otherwise  given in
accordance with Section 2.5 of these bylaws 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,  except as otherwise  provided  herein or required by law
(meaning,  here and  hereinafter,  as required  from time to time by the General
Corporation  Law  of  Delaware  or  the  certificate  of  incorporation  of  the
corporation). 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.

         2.5 Manner of Giving Notice; Affidavit of Notice. Written notice of any
meeting of stockholders, if mailed, is given when deposited in the United States
mail,  tice postage  prepaid,  directed to the  stockholder at his 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.

         2.6  Quorum.  At any  meeting  of the  stockholders,  the  holders of a
majority,  present  in  person or by  proxy,  of all of the  shares of the stock
entitled  to vote at the meeting  shall  constitute  a quorum for all  purposes,
unless or except to the  extent  that the  presence  of a larger  number  may be
required  by law.  Where a separate  vote by a class or classes is  required,  a
majority,  present in person or by proxy, of the shares of such class or classes
entitled  to take  action  with  respect  to that  vote  on
                                      -2-

that matter  shall  constitute  a quorum.  If a quorum  shall fail to attend any
meeting,  the chairman of the meeting may adjourn the meeting to another  place,
date or time.

          If a notice of any adjourned  special  meeting of stockholders is sent
to all stockholders entitled to vote thereat,  stating that it will be held with
those present  constituting a quorum,  those present at such  adjourned  meeting
shall  constitute a quorum (but in no event shall a quorum  consist of less than
one-third of the shares entitled to vote at the meeting),  and all matters shall
be  determined  by a  majority  of the  votes  cast at such  meeting,  except as
otherwise required by law.

         2.7 Adjourned Meeting;  Notice.  When a meeting is adjourned to another
time or place,  unless these bylaws 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  that 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,  a
notice of the  adjourned  meeting shall be given to each  stockholder  of record
entitled to vote at the meeting.

         2.8  Voting.  The  stockholders  entitled  to  vote at any  meeting  of
stockholders  shall be determined in accordance  with the  provisions of Section
2.11 of these bylaws,  subject to the  provisions of Sections 217 and 218 of the
General  Corporation Law of Delaware  (relating to voting rights of fiduciaries,
pledgors  and  joint  owners  of stock and to  voting  trusts  and other  voting
agreements).

          Each  stockholder  shall  have one (1) vote for  every  share of stock
entitled  to vote that is  registered  in his or her name on the record date for
the meeting (as  determined  in accordance  with Section 2.11 of these  bylaws),
except as otherwise provided herein or required by law.

          All  elections  shall be  determined by a plurality of the votes cast,
and except as otherwise  required by law or provided  herein,  all other matters
shall be determined by a majority of the votes cast affirmatively or negatively.

         2.9 Waiver of Notice. Whenever notice is required to be given under any
provision of the General  Corporation  Law of Delaware or of the  certificate of
incorporation  or these bylaws,  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  person  at a  meeting  shall
constitute a waiver of notice of such meeting,  except when the person attends a
meeting for the express  purpose of objecting,  at the beginning of the meeting,
to the transaction of any business because the meeting is not lawfully called or
convened.  Neither  the  business to be  transacted  at, nor the purpose of, any
regular or special meeting of the stockholders  need be specified in any written
waiver of notice unless so required by the certificate of incorporation or these
bylaws.
                                      -3-

         2.10  Stockholder  Action by Written  Consent  Without a  Meeting.  Any
action  required  or able to be  taken  at any  annual  or  special  meeting  of
stockholders may be taken without a meeting, without prior notice, and without a
vote if a consent 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 at its registered  office in Delaware,
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.  Delivery to the corporation's registered office shall be made by hand
or by certified or registered mail, return receipt requested.

          Every  written  consent  shall  bear  the  date of  signature  of each
stockholder  who signs the consent and no written  consent shall be effective to
take the corporate  action  referred to therein  unless,  within sixty (60) days
after the date the earliest  dated  consent is delivered to the  corporation,  a
written consent or consents signed by holders of a sufficient number of votes to
take action are  delivered to the  corporation  in the manner  prescribed in the
first paragraph of this section.

          Prompt notice of the taking of the corporate  action without a meeting
by less than unanimous written consent shall be given to those  stockholders who
have not  consented  in writing.  If the action which is consented to is such as
would have required the filing of a certificate under any section of the General
Corporation  Law of Delaware if such action had been voted on by stockholders at
a meeting thereof, then the certificate filed under such section shall state, in
lieu  of  any  statement  required  by  such  section  concerning  any  vote  of
stockholders,  that  written  notice  and  written  consent  have been  given as
provided in Section 228 of the General Corporation Law of Delaware.

         2.11 Record Date for Stockholder Notice;  Voting;  Giving Consents.  In
order that the corporation may determine the stockholders  entitled to notice of
or to vote  at any  meeting  of  stockholders  or any  adjournment  thereof,  or
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 a record date, which shall not be more than sixty
(60) nor less than ten (10) days before the date of such meeting,  nor more than
sixty (60) days prior to any other action.

 If the board of directors does not so fix a record date:

                  (i) The record date for determining  stockholders  entitled to
notice  of or to vote at a  meeting  of  stockholders  shall be at the  close of
business  on the day next  preceding  the day on which  notice is given,  or, if
notice is waived,  at the close of business on the day next preceding the day on
which the meeting is held.

                  (ii) The record date for determining  stockholders entitled to
receive payment of any dividend or other  distribution or allotment of rights or
to exercise any rights of change,
                                      -4-

conversion  or exchange of stock or for any other  purpose shall be at the close
of business  on the day on which the board of  directors  adopts the  resolution
relating thereto.

          In order that the corporation may determine the stockholders  entitled
to  consent to  corporate  action in  writing  without a  meeting,  the board of
directors may fix a record date,  which record date shall neither precede nor be
more than ten (10) days after the date upon which such  resolution is adopted by
the  board  of  directors.  Any  stockholder  of  record  seeking  to  have  the
stockholders  authorize  or take  action by written  consent  shall,  by written
notice to the  secretary,  request the board of  directors to fix a record date.
The board of directors  shall  promptly,  but in all events within ten (10) days
after the date on which such notice is received,  adopt a resolution  fixing the
record date.

          If the board of  directors  has not fixed a record  date  within  such
time,  the  record  date for  determining  stockholders  entitled  to consent to
corporate action in writing without a meeting, when no prior action by the board
of  directors  is  required  by law,  shall be the first  date on which a signed
written  consent  setting  forth the  action  taken or  proposed  to be taken is
delivered to the corporation in the manner  prescribed in the first paragraph of
Section 2.10 of these  bylaws.  If the board of directors has not fixed a record
date within such time and prior  action by the board of directors is required by
law,  the  record  date for  determining  stockholders  entitled  to  consent to
corporate  action in writing without a meeting shall be at the close of business
on the date on which the board of directors  adopts the  resolution  taking such
prior action.

          A determination  of stockholders of record entitled to notice of or to
vote at a meeting of stockholders shall apply to any adjournment of the meeting;
provided, however, that the board of directors may fix a new record date for the
adjourned meeting.

         2.12  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 by a
written  proxy,  filed in  accordance  with the  procedure  established  for the
meeting  or taking of action in  writing,  but no such  proxy  shall be voted or
acted upon after three (3) years from its date,  unless the proxy provides for a
longer  period.  Any  copy,   facsimile   telecommunication  or  other  reliable
reproduction  of the writing or  transmission  created  pursuant to this Section
2.12 may be substituted or used in lieu of the original  writing or transmission
for any and all purposes for which the original writing or transmission could be
used, provided that such copy, facsimile telecommunication or other reproduction
shall be a complete reproduction of the entire original writing or transmission.
The revocability of a proxy that states on its face that it is irrevocable shall
be governed by the provisions of Section 212(c) of the General  Corporation  Law
of Delaware.

         2.13 List of Stockholders  Entitled to Vote. The officer who has charge
of the stock ledger of a  corporation  shall prepare and make, at least ten (10)
days before every meeting of  stockholders,  a complete list of the stockholders
entitled to vote at the meeting, arranged in alphabetical order, and showing the
address of each  stockholder and the number of shares  registered
                                      -5-

in the name of each  stockholder.  Such list shall be open to the examination of
any  stockholder,  for any  purpose  germane  to the  meeting,  during  ordinary
business  hours,  for a period of at least ten (10) days  prior to the  meeting,
either at a place  within the city where the meeting is to be held,  which place
shall be specified in the notice of the meeting, or, if not so specified, at the
place where the meeting is to be held.  The list shall also be produced and kept
at the time and place of the meeting  during the whole time thereof,  and may be
inspected  by any  stockholder  who is  present.  Such list shall  presumptively
determine the identity of the  stockholders  entitled to vote at the meeting and
the number of shares held by each of them.

         2.14  Conduct  of  Business.  The  Board of  Directors  will  appoint a
Chairman  of the  meeting,  and  he/she  shall  be  authorized  to be the  final
authority on all matters of procedure at the meeting.  The rules  provided below
will  govern the  conduct of the  meeting of  stockholders  and will be strictly
enforced  to maintain an orderly  meeting.  Robert's  Rules of Order will not be
applicable and will not be utilized.

                  (i) Method of Obtaining the Floor.  Stockholders who desire to
address the meeting  must raise  their  hands and wait to be  recognized  by the
Chairman.  Only when a  stockholder  is recognized as having the floor may he or
she address the meeting.

                  (ii)  Discussion.  Persons  addressing  the meeting must limit
their remarks to the issue then under  consideration  by the stockholders and to
not more than five  minutes in  duration.  A  stockholder  will be  permitted to
address the meeting on a particular issue not more than three times.

                  (iii)  Stockholder   Proposals.   Stockholders  will  only  be
permitted  to address the meeting on  proposals  that are  included in the proxy
statement and proxy relating to that meeting.

          2.15 Inspectors of Election.  The  corporation  may, and to the extent
required by law, 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 person  presiding  at the meeting may, and to the
extent  required by law,  shall,  appoint one or more  inspectors  to act at the
meeting. Each inspector, before entering upon the discharge of his duties, shall
take and sign an oath  faithfully to execute the duties of inspector with strict
impartiality  and  according  to the best of his  ability.  Every  vote taken by
ballots shall be counted by an inspector or inspectors appointed by the chairman
of the meeting.

          2.16  Inspectors  of Election  and  Procedures  for  Counting  Written
Consents.  Within three (3) business  days after  receipt of the earliest  dated
consent delivered to the corporation in the manner provided in Section 228(c) of
the  Delaware  General  Corporation  Law or the  determination  by the  board of
directors of the corporation  that the corporation  should seek corporate action
by written  consent,  as the case may be, the  secretary  may engage  nationally
recognized  independent  inspectors of elections for the purpose of performing a
ministerial review of the validity of the
                                      -6-

consents and revocations.  The cost of retaining inspectors of election shall be
borne by the corporation.

          Consents and  revocations  shall be delivered to the  inspectors  upon
receipt by the corporation,  the stockholder or stockholders soliciting consents
or soliciting  revocations  in  opposition to action by consent  proposed by the
corporation (the "Soliciting  Stockholders")  or their proxy solicitors or other
designated  agents.  As soon as  consents  and  revocations  are  received,  the
inspectors  shall review the consents and revocations and shall maintain a count
of the number of valid and unrevoked consents.  As soon as practicable after the
earlier  of (i) sixty  (60) days after the date of the  earliest  dated  consent
delivered to the  corporation  in the manner  provided in Section  228(c) of the
Delaware  General  Corporation  Law or (ii) a written  request  therefor  by the
corporation or the Soliciting  Stockholders  (whichever is soliciting  consents)
(which request,  except in the case of corporate action by written consent taken
pursuant to the solicitations of not more than ten (10) persons,  may be made no
earlier than after such reasonable amount of time after the commencement date of
the applicable solicitation of consents as is necessary to permit the inspectors
to commence  and organize  their count,  but in no event less than five (5) days
after such  commencement  date),  notice of which  request shall be given to the
party opposing the  solicitation of consents,  if any, which request shall state
that the corporation or Soliciting Stockholders, as the case may be, have a good
faith  belief  that the  requisite  number of valid and  unrevoked  consents  to
authorize or take the action  specified  in the  consents  has been  received in
accordance with these bylaws, the inspectors shall issue a preliminary report to
the corporation and the Soliciting Stockholders stating: (i) the number of valid
consents;  (ii) the number of valid  revocations;  (iii) the number of valid and
unrevoked  consents;  (iv) the  number of  invalid  consents;  (v) the number of
invalid  revocations;  and (vi) whether,  based on their preliminary  count, the
requisite number of valid and unrevoked  consents has been obtained to authorize
or take the action specified in the consents.

          Unless the corporation and the Soliciting  Stockholders shall agree to
a shorter or longer period,  the  corporation  and the  Soliciting  Stockholders
shall have 48 hours to review the  consents  and  revocations  and to advise the
inspectors  and the  opposing  party in  writing as to  whether  they  intend to
challenge the preliminary  report of the inspectors.  If no written notice of an
intention to challenge the preliminary  report is received within 48 hours after
the inspectors'  issuance of the preliminary  report, the inspectors shall issue
to the corporation and the Soliciting Stockholders their final report containing
the information from the inspectors'  determination  with respect to whether the
requisite  number of valid and unrevoked  consents was obtained to authorize and
take the action specified in the consents.  If the corporation or the Soliciting
Stockholders  issue written notice of an intention to challenge the  inspectors'
preliminary  report  within  48 hours  after  the  issuance  of that  report,  a
challenge   session  shall  be  scheduled  by  the  inspectors  as  promptly  as
practicable.  A  transcript  of the  challenge  session  shall be  recorded by a
certified court reporter.  Following  completion of the challenge  session,  the
inspectors  shall as promptly  as  practicable  issue their final  report to the
corporation  and the  Soliciting  Stockholders,  which report shall  contain the
information  included in the  preliminary  report,  plus all changes made to the
vote  totals as a result of the  challenge  and a  certification  of whether the
requisite  number of valid and  unrevoked  consents was
                                      -7-

obtained to authorize or take the action  specified in the  consents.  A copy of
the final  report of the  inspectors  shall be included in the book in which the
proceedings of meetings of stockholders are recorded.

         2.17 Election Not To Be Subject to Arizona  Control Share  Acquisitions
Statute.  The  corporation  elects not to be subject  to Title 10,  Chapter  23,
Article  2  of  the  Arizona  Revised   Statutes   relating  to  "Control  Share
Acquisitions."

                                   ARTICLE III
                                    DIRECTORS

         3.1 Powers. Subject to the provisions of the General Corporation Law of
Delaware and any limitations in the certificate of incorporation or these bylaws
relating  to  action  required  to be  approved  by the  stockholders  or by the
outstanding shares, 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 number of directors  of the  corporation
shall be five (5). This number may be changed by a duly adopted amendment to the
certificate  of  incorporation  or by an  amendment  to this  bylaw  adopted  by
resolution of the board of directors or by the stockholders.

          No reduction  of the  authorized  number 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 bylaws, at each annual meeting of stockholders,
directors  of the  corporation  shall  be  elected  to  hold  office  until  the
expiration  of the term for which they are elected,  and until their  successors
have been duly elected and qualified; except that if any such election shall not
be so held, such election shall take place at a stockholders' meeting called and
held in accordance with the Delaware General Corporation Law.

          Directors  need  not  be  stockholders   unless  so  required  by  the
certificate of incorporation or these bylaws,  wherein other  qualifications for
directors may be prescribed.

          Nominations  for election to the board of directors of the corporation
at an annual  meeting of  stockholders  may be made by the board or on behalf of
the  board  by a  nominating  committee  appointed  by  the  board,  or  by  any
stockholder of the corporation entitled to vote for the election of directors at
such  meeting.  Such  nominations,  other than those made by or on behalf of the
board,  shall be made by notice in  writing  received  by the  secretary  of the
corporation  not less than  thirty (30) days nor more than sixty (60) days prior
to the  date of the  annual  meeting;  provided,  however,  that  if  less  than
thirty-five  (35) days  notice of the  meeting  is given to  stockholders,  such
nomination shall have been received by the secretary not later than the close of
business  on the  seventh  (7th) day
                                      -8-

following  the day on which the notice was mailed.  Such notice  shall set forth
(i) the name and address of the  stockholder who intends to make the nomination;
(ii) a representation  that the nominating  stockholder is a holder of record of
stock of the corporation  entitled to vote at such meeting and intends to appear
in  person  or by proxy at the  meeting  and  nominate  the  person  or  persons
specified in the notice;  (iii) the number of shares of stock held  beneficially
and of record  by the  nominating  stockholder;  (iv) the  name,  age,  business
address  and,  if known,  residence  address of each  nominee  proposed  in such
notice;  (v) the principal  occupation  or employment of such nominee;  (vi) the
number  of shares of stock of the  corporation  beneficially  owned by each such
nominee;  (vii) a description of all arrangements or understandings  between the
nominating  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 the nominating  stockholder;  (viii) any other information concerning
the nominee that must be disclosed of nominees in proxy  solicitations  pursuant
to  Regulation  14A  under the  Securities  Exchange  Act of 1934;  and (ix) the
consent of such nominee to serve as a director of the corporation if so elected.

          The  chairman  of  the  annual  meeting  may,  if the  facts  warrant,
determine  and  declare  to the  meeting  that a  nomination  was  not  made  in
accordance with the foregoing  procedure.  If such determination and declaration
is made, the defective nomination shall be disregarded.

         3.4 Resignation and Vacancies. Any director may resign at any time upon
written notice to the corporation. When one or more directors so resigns and the
resignation is effective at a future date, only a majority of the directors then
in office,  including those who have so resigned,  shall have power to fill such
vacancy or vacancies,  the vote thereon to take effect when such  resignation or
resignations  shall  become  effective,  and each  director so chosen shall hold
office as provided in this section in the filling of other vacancies.

          Unless otherwise provided in the certificate of incorporation or these
bylaws:

                  (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 only by a
majority of the directors  then in office,  even if less than a quorum,  or by a
sole remaining director.

                  (ii)  Whenever the holders of any class or classes of stock or
series  thereof are entitled to elect one or more directors by the provisions of
the certificate of incorporation,  vacancies and newly created  directorships of
such  class or  classes  or  series  may be  filled  only by a  majority  of the
directors  elected by such class or classes or series thereof then in office, or
by a sole remaining director so elected.

          If at any time, by reason of death or resignation or other cause,  the
corporation  should  have 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 like  responsibility for the person or estate
                                      -9-

of a stockholder,  may call a special meeting of stockholders in accordance with
the provisions of the certificate of incorporation or these bylaws, or may apply
to the Court of Chancery for a decree summarily ordering an election as provided
in Section 211 of the General Corporation Law of Delaware.

          If,  at  the  time  of  filling  any  vacancy  or  any  newly  created
directorship,  the directors then in office  constitute  less than a majority of
the whole board (as constituted  immediately  prior to any such increase),  then
the Court of Chancery may, upon  application of any  stockholder or stockholders
holding at least ten (10)  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 be held to fill any such  vacancies or newly created  directorships,
or to replace the directors chosen by the directors then in office as aforesaid,
which election shall be governed by the provisions of Section 211 of the General
Corporation Law of Delaware as far as applicable.

         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 the State of Delaware.

          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.

         3.6 Regular Meetings.  Regular meetings of the board of directors shall
be held at such  place or  places,  on such date or  dates,  and at such time or
times as shall have been  established  by the board of directors and  publicized
among all directors. A notice of each regular meeting shall not be required.

         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 president
or secretary of the  corporation,  or by any two of the directors then in office
and shall be held at a place,  on a date and at a time as such  officer  or such
directors  shall fix.  Notice of the place,  date and time of special  meetings,
unless  waived,  shall be given to each director by mailing  written  notice not
less than two (2) days before the meeting or by sending a facsimile transmission
of the same not less than two (2) hours  before  the time of the  holding of the
meeting. If the circumstances warrant, notice may also be given personally or by
telephone  not less than two (2) hours  before  the time of the  holding  of the
meeting. Oral notice given 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  it to the
director. Unless otherwise indicated in the notice thereof, any and all business
may be transacted at a special meeting.
                                      -10-

         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 act of a majority of the directors present at any meeting at
which there is a quorum  shall be the act of the board of  directors,  except as
may be  otherwise  specifically  provided  by statute or by the  certificate  of
incorporation.  If a  quorum  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 is  initially  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 Delaware or of the  certificate of
incorporation  or these bylaws,  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  person  at a  meeting  shall
constitute a waiver of notice of such meeting,  except when the person attends a
meeting for the express  purpose of objecting,  at the beginning of the meeting,
to the transaction of any business because the meeting is not lawfully called or
convened.  Neither  the  business to be  transacted  at, nor the purpose of, any
regular  or special  meeting of the  directors,  or  members of a  committee  of
directors,  need be specified in any written waiver of notice unless so required
by the certificate of incorporation or these bylaws.

         3.10  Adjourned  Meeting;  Notice.  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.

         3.11  Board  Action  by  Written  Consent  Without  a  Meeting.  Unless
otherwise  restricted by the certificate of incorporation  or these bylaws,  any
action  required  or  permitted  to be  taken  at any  meeting  of the  board of
directors,  or of any committee  thereof,  may be taken without a meeting if all
members  of the  board or  committee,  as the case may be,  consent  thereto  in
writing and the writing or writings are filed with the minutes of proceedings of
the board or committee.

         3.12 Fees and Compensation of Directors. Unless otherwise restricted by
the certificate of incorporation  or these bylaws,  the board of directors shall
have the authority to fix the  compensation  of directors.  The directors may be
paid their  expenses,  if any,  of  attendance  of each  meeting of the board of
directors  and may be paid a fixed sum for  attendance  at each  meeting  of the
board of  directors  or a stated  salary  as  director.  No such  payment  shall
preclude any director  from serving the  corporation  in any other  capacity and
receiving compensation  therefor.  Members of special or standing committees may
be allowed like compensation for attending committee meetings.

         3.13 Approval of Loans to Officers.  The corporation may lend money to,
or  guarantee  any  obligation  of, or  otherwise  assist  any  officer or other
employee of the  corporation  or of its
                                      -11-

subsidiaries,  including  any  officer  or  employee  who is a  director  of the
corporation  or its  subsidiaries,  whenever,  in the judgment of the directors,
such loan,  guaranty or  assistance  may  reasonably  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 in this section  contained shall be deemed to
deny, limit or restrict the powers of guaranty or warranty of the corporation at
common law or under any statute.

         3.14 Removal of Directors.  Unless otherwise  restricted by statute, by
the certificate of incorporation or by these bylaws,  any director or the entire
board of directors may be removed,  with or without  cause,  by the holders of a
majority of the shares then entitled to vote at an election of directors.

          No reduction  of the  authorized  number of  directors  shall have the
effect of removing any director prior to the expiration of such  director's term
of office.

         3.15  Conduct of  Business.  At any meeting of the board of  directors,
business shall be transacted in such order and manner as the board may from time
to time determine, and all matters shall be determined by the vote of a majority
of the directors  present,  except as otherwise  provided  herein or required by
law.

         3.16  Presumption  of Assent.  A  director  of the  corporation  who is
present at a meeting of the board of directors at which action on any  corporate
matter is taken shall be  conclusively  presumed to have  assented to the action
taken  unless his  dissent  shall be entered  in the  minutes of the  meeting or
unless he shall file his written  dissent to such action with the person  acting
as the secretary of the meeting before the adjournment  thereof or shall forward
such dissent by registered mail to the secretary of the corporation  immediately
after the adjournment of the meeting. Such right to dissent shall not apply to a
director who voted in favor of such action.


                                   ARTICLE IV
                                   COMMITTEES

         4.1 Committees of Directors.  The board of directors may, by resolution
passed by a majority of the whole board, designate one or more committees,  with
each  committee to consist of one or more of the  directors of the  corporation.
The board 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 he or they 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 the bylaws of the
corporation,
                                      -12-

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 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  Delaware,  fix  the  designation  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 Section 251 or 252 of the General Corporation Law
of Delaware,  (iii) recommend to the stockholders the sale, lease or exchange of
all  or  substantially  all of  the  corporation's  property  and  assets,  (iv)
recommend to the  stockholders a dissolution of the  corporation or a revocation
of a dissolution,  or (v) amend the bylaws of the  corporation;  and, unless the
board resolution  establishing the committee,  a supplemental  resolution of the
board of directors,  the bylaws or the certificate of incorporation expressly so
provide,  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
Delaware.

         4.2 Committee Minutes. Each committee shall keep regular minutes of its
meetings and report the same to the board of directors when required.

         4.3  Meetings  and  Action  of  Committees.  Meetings  and  actions  of
committees  shall be governed  by, and held and taken in  accordance  with,  the
provisions  of Article III of these  bylaws,  Section 3.5 (place of meetings and
meetings by  telephone),  Section 3.6 (regular  meetings),  Section 3.7 (special
meetings  and  notice),  Section 3.8  (quorum),  Section 3.9 (waiver of notice),
Section 3.10  (adjournment and notice of adjournment),  and Section 3.11 (action
without a  meeting),  with such  changes in the  context of those  bylaws 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 may also be
called by  resolutions  of the board of  directors,  and that  notice of special
meetings of committees shall also be given to all alternate  members,  who shall
have the right to attend all meetings of the  committee.  The board of directors
may adopt rules for the  government of any committee not  inconsistent  with the
provisions of these bylaws.
                                      -13-

                                    ARTICLE V

empower the president to appoint, such other officers and agents as the business
of the corporation may require,  each of whom shall hold office for such period,
have such authority,  and perform such duties as are provided in these bylaws or
as the board of directors may from time to time determine.

         5.4 Removal and  Resignation  of Officers.  Any officer may be removed,
either with or without  cause,  by an  affirmative  vote of the  majority of the
board of directors at any regular or special  meeting of the board or, except in
the case of an officer  chosen by the board of  directors,  by any officer  upon
whom such power of removal may be conferred by the board of directors.

          Any  officer  may resign at any time by giving  written  notice to the
corporation.  Any  resignation  shall take  effect at the date of the receipt of
that notice or at any later time specified in that notice; and, unless otherwise
specified  in that  notice,  the  acceptance  of the  resignation  shall  not be
necessary to make it effective.

         5.5  Vacancies in Offices.  Any vacancy  occurring in any office of the
corporation shall be filled in the manner prescribed in these bylaws for regular
appointments to that office.

directors and exercise and perform such other powers and duties as may from time

these  bylaws.  If there is no  president,  then the chairman of the board shall
also be the chief executive officer of the corporation and shall have the powers
and duties prescribed in Section 5.7 of these bylaws.

         5.7 President.  Subject to such supervisory  powers,  if any, as may be
given by the board of directors  to the chairman of the board,  if there be such
an  officer,  the  president  shall  be  the
                                      -14-

chief executive officer of the corporation and shall,  subject to the control of
the board of directors, have general supervision,  direction, and control of the
business and the officers of the  corporation.  He shall preside at all meetings
of the  stockholders  and, in the absence or  nonexistence  of a chairman of the
board,  at all  meetings  of the board of  directors.  He shall have the general
powers and duties of management  usually  vested in the office of president of a
corporation  and shall have such other powers and duties as may be prescribed by
the board of directors or these bylaws.

         5.8 Vice President. In the absence or disability of the president,  the
vice  presidents,  if any,  in  order of  their  rank as  fixed by the  board of
directors  or,  if not  ranked,  a vice  president  designated  by the  board of
directors,  shall  perform  all the duties of the  president  and when so acting

officer" of the corporation  includes any person (i) who is or was a director or

         7.1  Maintenance  and  Inspection of Records.  The  corporation  shall,
either  at its  principal  executive  office  or at  such  place  or  places  as
designated by the board of directors,  keep a record of its stockholders listing

stockholder,  a copy of these bylaws as amended to date,  accounting  books, and
other records.

         7.2  Inspection  by  Directors.  Any  director  shall have the right to
examine the  corporation's  stock ledger,  a list of its  stockholders,  and its
other books and records for a purpose  reasonably  related to his  position as a
director. The Court of Chancery is hereby vested with the exclusive jurisdiction
to determine whether a director is entitled to the inspection  sought. The Court
may summarily  order the  corporation  to permit the director to inspect any and
all books and records,  the stock ledger,  and the stock list and to make copies
or  extracts  therefrom.  The  Court  may,  in  its  discretion,  prescribe  any
limitations or conditions with reference to the inspection,  or award such other
and further relief as the Court may deem just and proper.

                                  ARTICLE VIII
                                 GENERAL MATTERS

         8.1 Checks.  From time to time, the board of directors  shall determine
by  resolution  which person or persons may sign or endorse all checks,  drafts,
other orders for payment of money, notes or other evidences of indebtedness that
are issued in the name of or payable to the corporation, and only the persons so
authorized shall sign or endorse those instruments.

         8.2  Execution of Corporate  Contracts  and  Instruments.  The board of
directors,  except as otherwise  provided in these  bylaws,  may  authorize  any
officer or officers,  or agent or agents,  to enter into any contract or execute
any instrument in the name of and on behalf of the  corporation;  such authority
may be general or  confined  to  specific  instances.  Unless so  authorized  or
ratified by the board of directors or within the agency power of an officer,  no
officer,  agent or  employee  shall  have any  power  or  authority  to bind the
corporation  by any contract or  engagement or to pledge its credit or to render
it liable for any purpose or for any amount.

         8.3 Stock Certificates; Partly Paid Shares. The shares of a 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 its stock 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
                                      -18-

corporation by the chairman or vice-chairman  of the board of directors,  or the
president or vice-president,  and by the treasurer or an assistant treasurer, or
the secretary or an assistant  secretary of such  corporation  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,  it may be issued by the corporation  with the same
effect as if he were such  officer,  transfer  agent or registrar at the date of
issue.

          The  corporation  may  issue  the  whole or any part of its  shares as
partly paid and subject to call for the  remainder  of the  consideration  to be
paid  therefor.  Upon  the  face or back of each  stock  certificate  issued  to
represent  any such  partly  paid  shares,  upon the  books and  records  of the
corporation in the case of uncertificated  partly paid shares,  the total amount
of the  consideration  to be paid  therefor and the amount paid thereon shall be
stated.  Upon  the  declaration  of any  dividend  on  fully  paid  shares,  the
corporation  shall declare a dividend upon partly paid shares of the same class,
but only upon the basis of the  percentage  of the  consideration  actually paid
thereon.

         8.4  Special  Designation  on  Certificates.   If  the  corporation  is
authorized  to issue more than one class of stock or more than one series of any
class,  then the powers,  the designations,  the preferences,  and the 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 shall be set forth in full or  summarized  on the 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 Delaware, in lieu of the foregoing
requirements  there may be set forth on the face or back of the certificate that
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, the designations, the preferences, and the 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.

         8.5 Lost  Certificates.  Except as provided in this Section 8.5, no new
certificates  for  shares  shall  be  issued  to  replace  a  previously  issued
certificate unless the latter is surrendered to the corporation and cancelled at
the  same  time.  The  corporation  may  issue a new  certificate  of  stock  or
uncertificated shares in the 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  his  legal
representative,  to give the  corporation  a bond  sufficient  to  indemnify  it
against any claim that may be made  against it on account of the  alleged  loss,
theft  or  destruction  of any  such  certificate  or the  issuance  of such new
certificate or uncertificated shares.

         8.6 Construction;  Definitions.  Unless the context requires otherwise,
the general  provisions,  rules of construction,  and definitions in the General
Corporation  Law of Delaware  shall  govern the  construction  of these  bylaws.
Without limiting the generality of this provision,  the
                                      -19-

singular  number  includes the plural,  the plural number includes the singular,
and the term "person" includes both a corporation and a natural person.

         8.7  Dividends.  The  directors  of  the  corporation,  subject  to any
restrictions  contained in (i) the General  Corporation  Law of Delaware or (ii)
the certificate of incorporation,  may declare and pay dividends upon the shares
of its capital stock.  Dividends may be paid in cash, in property,  or in shares
of the corporation's capital stock.

          The directors of the corporation may set apart out of any of the funds
of the corporation  available for dividends a reserve or reserves for any proper
purpose and may abolish any such reserve. Such purposes shall include but not be
limited to equalizing  dividends,  repairing or maintaining  any property of the
corporation, and meeting contingencies.

         8.8 Fiscal Year. The fiscal year of the  corporation  shall be fixed by
resolution  of the  board  of  directors  and may be  changed  by the  board  of
directors.

         8.9 Seal.  The  corporation  may adopt a corporate  seal,  which may be
altered at pleasure,  and may use the same by causing it or a facsimile  thereof
to be impressed or affixed or in any other manner reproduced.

         8.10  Transfer  of Stock.  Upon  surrender  to the  corporation  or the
transfer agent of the  corporation of a certificate  for shares duly endorsed or
accompanied  by proper  evidence  of  succession,  assignment  or  authority  to
transfer,  it shall be the duty of the corporation to issue a new certificate to
the  person  entitled  thereto,  cancel  the old  certificate,  and  record  the
transaction in its books.

         8.11 Stock Transfer  Agreements.  The  corporation  shall have power to
enter into and perform any agreement with any number of  stockholders of any one
or more classes of stock of the  corporation  to restrict the transfer of shares
of  stock  of the  corporation  of  any  one  or  more  classes  owned  by  such
stockholders  in any manner not  prohibited  by the General  Corporation  Law of
Delaware.

         8.12  Registered  Stockholders.  The  corporation  shall be entitled to
recognize the exclusive  right of a person  registered on its books as the owner
of shares to receive  dividends and to vote as such owner,  shall be entitled to
hold liable for calls and assessments the person  registered on its books as the
owner of shares,  and shall not be bound to  recognize  any  equitable  or other
claim to or  interest  in such  share or shares on the part of  another  person,
whether  or not it  shall  have  express  or other  notice  thereof,  except  as
otherwise provided by the laws of Delaware.

         8.13  Notices.  Except as  otherwise  specifically  provided  herein or
required by law, all notices required to be given to any stockholder,  director,
officer,  employee  or agent  shall be in writing  and may in every  instance be
effectively  given by hand  delivery,  by mail,  postage  paid,  or by
                                      -20-

facsimile transmission.  Any such notice shall be addressed to such stockholder,
director,  officer, employee or agent at his last known address as it appears on
the  books of the  corporation.  The  time  when  such  notice  shall be  deemed
received,  if hand  delivered,  or  dispatched,  if  sent by mail or  facsimile,
transmission, shall be the time of the giving of the notice.

of the shares of the  corporation's  stock  entitled to vote in the  election of
directors, voting as one class.
