                      FAIR, ISAAC AND COMPANY, INCORPORATED

              (as amended and restated effective February 5, 2002)

                                    ARTICLE I

                                     Offices

         1.1 Registered  Office.  The registered  office shall be in the City of
Wilmington, County of New Castle, State of Delaware.

         1.2 Additional  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 Annual  Meetings.  An annual meeting of stockholders  shall be held
for the election of directors and scheduled for the first Tuesday of February of
each year, at 10:00 A.M. or, should such day fall upon a legal  holiday,  at the
same time on the next business day thereafter that is not a legal holiday, or at
such other date and time as may be  designated  by the Board of  Directors  from
time to time.  The  annual  meeting  of  stockholders  may be held at such place
either  within  or  without  the  State  of  Delaware,  or by  means  of  remote
communication, as may be designated by the Board of Directors from time to time;
in the absence of any such designation,  the annual meeting shall be held at the
principal   executive  offices  of  the  Corporation.   At  such  meeting,   the
stockholders  shall elect  directors and transact such other  business as may be
properly brought before the meeting.

         To be properly  brought  before the annual  meeting,  business  must be
either (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  of record.  In
addition  to any other  applicable  requirements,  for  business  to be properly
brought before the annual meeting by a stockholder,  the  stockholder  must have
given timely notice thereof in writing to the Secretary of the  Corporation.  To
be timely, a stockholder's  notice must be delivered by a nationally  recognized
courier service or mailed by first class United States mail, postage or delivery
charges  prepaid,  and  received  at  the  principal  executive  offices  of the
Corporation, addressed to the attention of the Secretary of the Corporation, not
less  than 60 days nor more  than 90 days  prior  to the  scheduled  date of the
meeting  (regardless of any  postponements,  deferrals or  adjournments  of that
meeting to a later date);  provided,  however, that in the event that the annual
meeting is held at a date other than the first Tuesday of February,  or the next
business day if such Tuesday is a legal holiday and less than 70 days' notice or
prior public disclosure of the date of the scheduled meeting is given or made to
stockholders,  notice by the  stockholder  to be timely must be so received  not
later than the earlier of (a) the close of  business  on the 10th day  following
the day on which such  notice of the date of the  scheduled  annual  meeting was
mailed or such public disclosure was made,  whichever first occurs,  and (b) two
days prior to the date of the scheduled meeting.  A 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,  (ii) the name and  record  address of the
stockholder  proposing  such  business,  (iii) the  class,  series and number of
shares of the Corporation that are owned  beneficially by the  stockholder,  and
(iv) any material interest of the stockholder in such business.  Notwithstanding
anything in these by-laws to the contrary, no business shall be conducted at the
annual meeting except in accordance with the procedures set forth in


                                      -1-


this Section 2.1; provided,  however,  that nothing in this Section 2.1 shall be
deemed to  preclude  discussion  by any  stockholder  of any  business  properly
brought before the annual meeting.

         The Chairman of the Board of Directors (or such other person  presiding
at the meeting in accordance  with Section 2.7 of these by-laws)  shall,  if the
facts  warrant,  determine  and declare to the  meeting  that  business  was not
properly  brought  before the meeting in accordance  with the provisions of this
Section 2.1, and if he or she should so determine, he or she shall so declare to
the meeting and any such business not properly  brought before the meeting shall
not be transacted.

         2.2 Special Meetings. Special meetings of stockholders may be called at
any time  only by the  Chairman  of the  Board of  Directors,  if any,  the Vice
Chairman  of the  Board of  Directors,  if any,  the  President  or the Board of
Directors,  to be held at such date, time and place (if any) as may be stated in
the  notice of the  meeting.  Business  transacted  at any  special  meeting  of
stockholders  shall be  limited  to the  purposes  stated  in the  notice of the
meeting.

         2.3 Notice of Meetings. Whenever stockholders are required or permitted
to take  any  action  at a  meeting,  notice  of the  meeting  shall be given in
accordance  with Section 2.4 which shall state the place (if any), date and hour
of the meeting, the means of remote communication (if any) by which stockholders
and  proxyholders may be deemed to be present in person and vote at such meeting
and, in the case of a special  meeting,  the  purpose or purposes  for which the
meeting is called.  Unless otherwise  provided by law, the notice of any meeting
shall be given not less than ten nor more than sixty days before the date of the
meeting to each stockholder entitled to vote at such meeting.

         2.4 Manner Of Giving  Notice.  Notice of any  meeting  of  stockholders
shall be given  personally,  by mail,  by  electronic  transmission  or by other
written  communication,  addressed to the  stockholder  at the address,  number,
electronic mail address or other location of that  stockholder  appearing on the
books of the  Corporation or given by the stockholder to the Corporation for the
purpose of notice. If no such address,  number,  email address or other location
appears on the Corporation's  books or is given,  notice shall be deemed to have
been given if sent to that  stockholder  by mail or telegraphic or other written
communication to the Corporation's  principal  executive office, or if published
at least once in a newspaper  of general  circulation  in the county  where that
office is  located.  Notice  shall be deemed to have been given at the time when
delivered  personally  or  deposited  in the  mail  or,  if sent  by  electronic
transmission,  as follows: (i) if by facsimile telecommunication,  when directed
to a number at which the stockholder has consented to receive notice, (ii) if by
electronic  mail,  when  directed  to an  electronic  mail  address at which the
stockholder  has  consented  to  receive  notice,  (iii) if by a  posting  on an
electronic  network  together with separate  notice to the  stockholder  of such
specific posting,  upon the later of (a) such posting and (b) the giving of such
separate notice, and (iv) if by any other form of electronic transmission,  when
directed to the stockholder.

         An affidavit of mailing or of electronic  transmission of any notice or
report in accordance  with the  provisions of this Section 2.4,  executed by the
Secretary,  Assistant  Secretary or any transfer agent or other agent,  shall be
prima facie evidence of the giving of the notice.

         2.5 Adjournments.  Any meeting of stockholders,  annual or special, may
adjourn from time to time to reconvene at the same or some other place (if any),
and notice need not be given of any such adjourned meeting if the time and place
(if any) 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 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.

         2.6 Quorum.  At each meeting of  stockholders,  except where  otherwise
provided  by law or the  certificate  of  incorporation  or these  by-laws,  the
holders of a majority of the outstanding  shares of each class of stock entitled
to vote at the  meeting,  present  in person  or  represented  by  proxy,  shall
constitute  a quorum.  For  purposes of the  foregoing,  two or more  classes or
series of stock shall be  considered a single  class if the holders  thereof are
entitled to vote together as a single class at the meeting.  In the absence of a
quorum the  stockholders  so present may, by majority vote,  adjourn the meeting
from time to time in the manner provided by Section 2.5 of these by-laws until a
quorum shall  attend.  Shares of its own capital  stock  belonging on the record
date for the meeting to


                                      -2-


the Corporation or to another corporation,  if a majority of the shares entitled
to vote in the election of directors of such other corporation is held, directly
or  indirectly,  by the  Corporation,  shall  neither be entitled to vote nor be
counted for quorum  purposes;  provided,  however,  that the foregoing shall not
limit the right of the  Corporation to vote stock,  including but not limited to
its own stock, held by it in a fiduciary capacity.

         If  authorized  by the Board of Directors in its sole  discretion,  and
subject to such  guidelines  and procedures as the Board of Directors may adopt,
stockholders  and   proxyholders   not  physically   present  at  a  meeting  of
stockholders may, by means of remote communication:

               (1) participate in a meeting of stockholders; and

               (2) be  deemed  present  in  person  and  vote  at a  meeting  of
          stockholders  whether such meeting is to be held at a designated place
          or  solely  by means of remote  communication,  provided  that (i) the
          Corporation  shall implement  reasonable  measures to verify that each
          person deemed present and permitted to vote at the meeting by means of
          remote  communication  is  a  stockholder  or  proxyholder,  (ii)  the
          Corporation  shall  implement  reasonable  measures  to  provide  such
          stockholders and proxyholders a reasonable  opportunity to participate
          in the meeting and to vote on matters  submitted to the  stockholders,
          including  an  opportunity  to  read or hear  the  proceedings  of the
          meeting substantially concurrently with such proceedings, and (iii) if
          any  stockholder  or  proxyholder  votes or takes other  action at the
          meeting  by means of  remote  communication,  a record of such vote or
          other action shall be maintained by the Corporation.

         2.7  Organization.  Meetings of stockholders  shall be presided over by
the  Chairman  of the  Board of  Directors,  if any,  or in the  absence  of the
Chairman of the Board of  Directors by the  President,  or in the absence of the
President by a Vice President,  or in the absence of the foregoing  persons by a
chairman  designated  by the  Board  of  Directors,  or in the  absence  of such
designation  by a chairman  chosen at the meeting.  The  Secretary  shall act as
secretary  of the  meeting,  or in the absence of the  Secretary by an Assistant
Secretary,  or in their  absence  the  chairman  of the  meeting may appoint any
person to act as secretary of the meeting.

         2.8 Voting;  Proxies.  Unless otherwise  provided in the certificate of
incorporation,  each stockholder entitled to vote at any meeting of stockholders
shall be entitled  to one vote for each share of stock held by such  stockholder
which has voting power upon the matter in question. Each stockholder entitled to
vote at a meeting of  stockholders or to express consent or dissent to corporate
action in writing  without a meeting may authorize  another person or persons to
act for such  stockholder  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 stockholder may revoke any
proxy which is not irrevocable by attending the meeting, whether in person or by
other means provided for in these by-laws or the  certificate of  incorporation,
and voting or by filing an instrument  in writing  revoking the proxy or another
duly executed proxy bearing a later date with the Secretary of the  Corporation.
Voting at meetings of stockholders need not be by written ballot and need not be
conducted  by  inspectors  unless the holders of a majority  of the  outstanding
shares of all classes of stock entitled to vote thereon  present in person or by
proxy  at such  meeting  shall  so  determine.  If  authorized  by the  Board of
Directors, votes may be submitted by electronic transmission,  provided that any
such  electronic  transmission  must  either  set  forth  or be  submitted  with
information from which it can be determined that the electronic transmission was
authorized by the  stockholder or  proxyholder.  At all meetings of stockholders
for the election of directors a plurality of the votes cast shall be  sufficient
to elect. With respect to other matters,  unless otherwise provided by law or by
the certificate of incorporation  or these by-laws,  the affirmative vote of the
holders of a majority of the shares of all classes of stock present in person or
represented  by proxy at the meeting and entitled to vote on the subject  matter
shall  be the  act of the  stockholders,  provided  that  (except  as  otherwise
required by law or by the certificate of  incorporation)  the Board of Directors
may require a larger vote upon any such matter.  Where a separate  vote by class
is required,  the affirmative vote of the holders of a majority of the shares of
each class present in person or represented by proxy at the meeting shall be the
act of such class,  except as otherwise provided by law or by the certificate of
incorporation or these by-laws.

         2.9 Fixing Date for  Determination of Stockholders of Record.  In order
that the Corporation may determine the stockholders  entitled to notice of or to
vote at any meeting of stockholders or any  adjournment


                                      -3-


thereof, or to express consent to corporate action in writing without a meeting,
or  entitled  to  receive  payment  of any  dividend  or other  distribution  or
allotment  of any rights,  or entitled to exercise  any rights in respect of any
change,  conversion  or exchange of stock or for the purpose of any other lawful
action,  the Board of Directors may fix, in advance,  a record date, which shall
not be more than sixty nor less than ten days  before the date of such  meeting,
nor more than sixty days prior to any other action.  If no record date is fixed:
(1) 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;  (2) the record  date for  determining  stockholders  entitled  to express
consent to corporate  action in writing without a meeting,  when no prior action
by the  Board of  Directors  is  necessary,  shall be the day on which the first
written  consent  is  expressed;   and  (3)  the  record  date  for  determining
stockholders  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.  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.

         2.10 List of Stockholders Entitled To Vote. The Secretary shall prepare
and make,  at least ten days before every  meeting of  stockholders,  a complete
list  of  the  stockholders  entitled  to  vote  at  the  meeting,  arranged  in
alphabetical  order,  and showing the address of each stockholder and the number
of shares registered in the name of each  stockholder.  Nothing contained herein
shall  require  the  Corporation  to include  electronic  mail  address or other
electronic  contact  information  on such  list.  Such list shall be open to the
examination  of any  stockholder,  for any purpose  germane to the meeting for a
period of at least ten days prior to the meeting: (i) on a reasonably accessible
electronic  network,  provided that the  information  required to gain access to
such list is provided  with the notice of the meeting,  or (ii) during  ordinary
business  hours at the principal  place of business of the  Corporation.  In the
event the meeting is to be held at a place,  the list shall 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. If the meeting is to be held solely
by  means  of  remote  communication,  then  the  list  shall  also  be  open to
examination  of any  stockholder  during  the  whole  time of the  meeting  on a
reasonably accessible electronic network, and the information required to access
such list shall be provided with the notice of the meeting.

         2.11  Consent of  Stockholders  in Lieu of  Meeting.  Unless  otherwise
provided in the certificate of  incorporation,  any action required by law to be
taken at any annual or special meeting of stockholders  of the  Corporation,  or
any  action  which  may be  taken  at any  annual  or  special  meeting  of such
stockholders, may be taken without a meeting, without prior notice and without a
vote,  if a consent 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.
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.

                                   ARTICLE III

                               Board of Directors

         3.1 Powers;  Number;  Qualifications.  The  business and affairs of the
Corporation  shall  be  managed  by or  under  the  direction  of the  Board  of
Directors,  except as may be otherwise  provided by law or in the certificate of
incorporation.  The number of  directors  which  shall  constitute  the Board of
Directors shall be seven (7). Directors need not be stockholders.

         3.2  Election;  Term  of  Office;   Resignation;   Removal;  Vacancies;
Nominations.  Each  director  shall  hold  office  until the  annual  meeting of
stockholders  next succeeding his or her election and until his or her successor
is elected and qualified or until his or her earlier resignation or removal. Any
director  may  resign  at  any  time  upon  notice  in  writing  or   electronic
transmission  to the Board of Directors or to the  President or the Secretary of
the  Corporation.  Such  resignation  shall  take  effect at the time  specified
therein, and unless otherwise specified therein


                                      -4-


no acceptance of such resignation  shall be necessary to make it effective.  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.  Unless otherwise  provided in the certificate of incorporation or
these  by-laws,  vacancies and newly created  directorships  resulting  from any
increase in the  authorized  number of  directors or from any other cause may be
filled by a  majority  of the  directors  then in office,  although  less than a
quorum, or by the sole remaining director.

         Only  persons  who are  nominated  in  accordance  with  the  following
procedures  shall be eligible for election as directors.  Nominations of persons
for  election  to the Board of  Directors  at the annual  meeting,  by or at the
direction of the Board of Directors,  may be made by any Nominating Committee or
person appointed by the Board of Directors;  nominations may also be made by any
stockholder  of record of the  Corporation  entitled to vote for the election of
directors at the meeting who complies  with the notice  procedures  set forth in
this Section 3.2. Such nominations, other than those made by or at the direction
of the Board of Directors, shall be made pursuant to timely notice in writing to
the Secretary of the Corporation.  To be timely, a stockholder's notice shall be
delivered by a nationally  recognized  courier  service or mailed by first class
United States mail,  postage or delivery  charges  prepaid,  and received at the
principal executive offices of the Corporation addressed to the attention of the
Secretary of the  Corporation  not less than 60 days nor more than 90 days prior
to the scheduled date of the meeting (regardless of any postponements, deferrals
or adjournments of that meeting to a later date);  provided,  however,  that, in
the case of an annual  meeting and in the event that the annual  meeting is held
at a date other than the first Tuesday of February,  or the next business day if
such  Tuesday is a legal  holiday and less than 70 days'  notice or prior public
disclosure  of  the  date  of  the  scheduled   meeting  is  given  or  made  to
stockholders,  notice by the  stockholder  to be timely must be so received  not
later than the earlier of (a) the close of  business  on the 10th day  following
the day on which such notice of the date of the scheduled  meeting was mailed or
such public  disclosure was made,  whichever first occurs, or (b) two days prior
to the date of the scheduled meeting. Such stockholder's notice to the Secretary
shall set forth (a) as to each person whom the stockholder  proposes to nominate
for election or reelection as a director,  (i) the name, age,  business  address
and residence address of the person, (ii) the principal occupation or employment
of the person,  (iii) the class, series and number of shares of capital stock of
the Corporation that are owned  beneficially by the person,  (iv) a statement as
to the  person's  citizenship,  and (v) any other  information  relating  to the
person  that is  required  to be  disclosed  in  solicitations  for  proxies for
election of directors  pursuant to Section 14 of the Securities  Exchange Act of
1934, as amended, and the rules and regulations promulgated thereunder;  and (b)
as to the stockholder  giving the notice, (i) the name and record address of the
stockholder and (ii) the class,  series and number of shares of capital stock of
the Corporation that are owned beneficially by the stockholder.  The Corporation
may  require  any  proposed  nominee to furnish  such other  information  as may
reasonably be required by the  Corporation to determine the  eligibility of such
proposed  nominee to serve as director of the  Corporation.  No person  shall be
eligible  for  election as a director of the  Corporation  unless  nominated  in
accordance with the procedures set forth herein.

         In  connection  with any annual  meeting,  the Chairman of the Board of
Directors  (or such other person  presiding at such meeting in  accordance  with
Section 2.7 of these by-laws) shall, if the facts warrant, determine and declare
to the meeting that a nomination  was not made in accordance  with the foregoing
procedure,  and if he or she should so determine,  he or she shall so declare to
the meeting and the defective nomination shall be disregarded.

         3.3 Regular meetings. Regular meetings of the Board of Directors may be
held at such places within or without the State of Delaware and at such times as
the Board of Directors  may from time to time  determine,  and if so  determined
notice thereof need not be given.

         3.4 Special Meetings. Special meetings of the Board of Directors may be
held at any time or place  within  or  without  the State of  Delaware  whenever
called by the Chairman of the Board of  Directors,  if any, by the Vice Chairman
of the Board of  Directors,  if any, by the  President or by any two  directors.
Reasonable  notice  thereof shall be given by the person or persons  calling the
meeting.

         3.5 Participation in Meetings by Conference Telephone Permitted. Unless
otherwise  restricted by the  certificate  of  incorporation  or these  by-laws,
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 of such
committee,  as the case may be,  by means of  conference  telephone  or  similar
communications equipment by means of which all persons participating


                                      -5-


in the meeting can hear each other,  and  participation in a meeting pursuant to
this by-law shall constitute presence in person at such meeting.

         3.6 Quorum;  Vote Required for Action.  At all meetings of the Board of
Directors  one third of the  entire  Board of  Directors,  but not less than two
shall  constitute  a  quorum  for the  transaction  of  business.  The vote of a
majority  of the  directors  present  at a meeting  at which a quorum is present
shall  be  the  act  of  the  Board  of  Directors  unless  the  certificate  of
incorporation or these by-laws shall require a vote of a greater number. In case
at any  meeting of the Board of  Directors a quorum  shall not be  present,  the
members of the Board of  Directors  present may adjourn the meeting from time to
time until a quorum shall attend.

         3.7 Organization.  Meetings of the Board of Directors shall be presided
over by the Chairman of the Board of Directors, if any, or in the absence of the
Chairman  of the  Board  of  Directors  by the  Vice  Chairman  of the  Board of
Directors,  if any,  or in the  absence  of the Vice  Chairman  of the  Board of
Directors  by the  President,  or in their  absence by a chairman  chosen at the
meeting.  The  Secretary,  or in the  absence  of  the  Secretary  an  Assistant
Secretary,  shall act as  secretary  of the  meeting,  but in the absence of the
Secretary  and any  Assistant  Secretary the chairman of the meeting may appoint
any person to act as secretary of the meeting.

         3.8 Action by Directors Without a Meeting.  Unless otherwise restricted
by the  certificate of  incorporation  or these by-laws,  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 of
Directors or of such  committee,  as the case may be, consent thereto in writing
or  electronic   transmission,   and  the  writing  or  writings  or  electronic
transmission or  transmissions  are filed with the minutes of proceedings of the
Board of  Directors  or  committee.  All such  actions  by  written  consent  or
electronic transmission shall have the same force and effect as a unanimous vote
of such directors.

         3.9  Compensation  of Directors.  The Board of Directors shall have the
authority to fix the compensation of directors.

                                   ARTICLE IV

                                   Committees

         4.1  Executive  Committee.  The Board of Directors  may, by  resolution
approved by at least a majority of the authorized number of directors, establish
and appoint  one or more  members of the Board of  Directors  to  constitute  an
Executive  Committee  (the  "Executive  Committee"),  with such powers as may be
expressly delegated to it by resolution of the Board of Directors. The Executive
Committee  shall  act only in the  intervals  between  meetings  of the Board of
Directors  and  shall be  subject  at all times to the  control  of the Board of
Directors.

         4.2 Committees.  In addition to the Executive  Committee,  the Board of
Directors  may,  by  resolution  passed  by a  majority  of the  whole  Board of
Directors,  designate one or more other committees, each committee to consist of
one or more of the  directors of the  Corporation.  The Board of  Directors  may
designate one or more directors as alternate  members of any committee,  who may
replace any absent or  disqualified  member at any meeting of the committee.  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 place of any
such absent or disqualified  member. Any such committee,  to the extent provided
in the resolution of the Board of Directors, shall have and may exercise all the
powers and authority of the Board of Directors in the management of the business
and affairs of the Corporation, and may authorize the seal of the Corporation to
be affixed to all papers which may require it; but no such committee  shall have
power or authority in reference  to amending 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 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


                                      -6-


Corporation), adopting an agreement of merger or consolidation,  recommending to
the stockholders the sale, lease or exchange of all or substantially  all of the
Corporation's   property  and  assets,   recommending  to  the   stockholders  a
dissolution  of the  Corporation  or a revocation  of  dissolution,  removing or
indemnifying  directors or amending  these by-laws;  and,  unless the resolution
expressly so provides,  no such  committee  shall have the power or authority to
declare a dividend or to authorize  the issuance of stock or adopt a certificate
of ownership and merger.

         4.3 Committee Rules.  Unless the Board of Directors otherwise provides,
the committee  designated by the Board of Directors may adopt,  amend and repeal
rules for the conduct of its  business.  In the  absence of a  provision  by the
Board  of  Directors  or a  provision  in the  rules  of such  committee  to the
contrary,  a  majority  of the  entire  authorized  number  of  members  of such
committee shall constitute a quorum for the transaction of business, the vote of
a  majority  of the  members  present at a meeting at the time of such vote if a
quorum is then present shall be the act of such committee, and in other respects
each  committee  shall  conduct its  business in the same manner as the Board of
Directors conducts its business pursuant to Article III of these by-laws.

                                    ARTICLE V

                                    Officers

         5.1 Officers; Election. As soon as practicable after the annual meeting
of stockholders in each year, the Board of Directors shall elect a President and
a  Secretary,  and it may, if it so  determines,  elect from among its members a
Chairman of the Board of Directors. The Board of Directors may also elect one or
more  Vice  Presidents,  one or  more  Assistant  Vice  Presidents,  one or more
Assistant Secretaries, a Treasurer and one or more Assistant Treasurers and such
other officers as the Board of Directors may deem  desirable or appropriate  and
may give  any of them  such  further  designations  or  alternate  titles  as it
considers  desirable.  Any  number of  offices  may be held by the same  person;
provided, however, that the offices of President and Secretary shall not be held
by the same person.

         5.2  Term  of  Office;  Resignation;   Removal;  Vacancies.  Except  as
otherwise  provided in the  resolution  of the Board of  Directors  electing any
officer,  each officer shall hold office until the first meeting of the Board of
Directors  after the annual meeting of  stockholders  next succeeding his or her
election,  and until his or her  successor is elected and qualified or until his
or her earlier  resignation or removal.  Any officer may resign at any time upon
written notice to the Board of Directors or to the President or the Secretary of
the  Corporation.  Such  resignation  shall  take  effect at the time  specified
therein,   and  unless  otherwise   specified  therein  no  acceptance  of  such
resignation shall be necessary to make it effective.  The Board of Directors may
remove any officer with or without cause at any time.  Any such removal shall be
without  prejudice to the contractual  rights of such officer,  if any, with the
Corporation,  but  the  election  of an  officer  shall  not  of  itself  create
contractual  rights.  Any vacancy  occurring in any office of the Corporation by
death, resignation, removal or otherwise may be filled for the unexpired portion
of the term by the Board of Directors at any regular or special meeting.

         5.3 Powers and Duties.  The officers of the Corporation shall have such
powers and duties in the  management  of the  Corporation  as shall be stated in
these  by-laws  or in a  resolution  of the  Board  of  Directors  which  is not
inconsistent  with these by-laws and, to the extent not so stated,  as generally
pertain to their  respective  offices,  subject  to the  control of the Board of
Directors.  The Board of Directors may require any officer, agent or employee to
give security for the faithful performance of his or her duties.

         5.4  Chairman of the Board of  Directors.  The Chairman of the Board of
Directors, if there shall be such an officer, shall, if present,  preside at all
meetings of the Board of  Directors  and  exercise and perform such other powers
and duties as may be from time to time assigned to him by the Board of Directors
or prescribed by the by-laws.

         5.5 President.  The President shall be the chief  executive  officer of
the Corporation.  Subject to such supervisory powers, if any, as may be given by
the Board of Directors to the  Chairman of the Board of  Directors,  if there be
such an  officer,  and  subject to the  provisions  of these  by-laws and to the
direction of the Board of Directors,  the President shall have  supervision over
and may  exercise  general  executive  powers of the business and affairs of the
Corporation  and shall perform all duties and have all powers which are commonly
incident to the office of chief


                                      -7-


executive or which are delegated to him by the Board of Directors. He shall have
power to sign all stock  certificates,  contracts and other  instruments  of the
Corporation  which  are  authorized  and  shall  have  general  supervision  and
direction of all of the other officers, employees and agents of the Corporation.
The  President  shall be ex officio,  a member of all the  standing  committees,
including the Executive  Committee.  In the absence of the Chairman of the Board
of  Directors,  the  President  shall  preside at all  meetings  of the Board of
Directors.

         5.6 Vice President. In the absence of the President or in his inability
or refusal to act,  the Vice  President  (or in the event there be more than one
Vice President, the Vice Presidents in the order designated by the directors, or
in the absence of any  designation,  then in the order of their  election) shall
perform  the duties of the  President,  and when so  acting,  shall have all the
powers of and be subject to all the  restrictions  upon the President.  The Vice
Presidents  shall  perform  such other  duties and have such other powers as the
Board of Directors may from time to time prescribe.

         5.7 Secretary.  The Secretary shall attend all meetings of the Board of
Directors and all meetings of the stockholders and record all the proceedings of
the  meetings of the  Corporation  and of the Board of Directors in a book to be
kept for that purpose and shall perform like duties for the standing  committees
when  required.  He shall give, or cause to be given,  notice of all meetings of
the  stockholders  and  special  meetings of the Board of  Directors,  and shall
perform  such other  duties as may be  prescribed  by the Board of  Directors or
president,  under whose  supervision  he shall be. He shall have  custody of the
corporate seal of the Corporation and he, or an Assistant Secretary,  shall have
authority to affix the same to any instrument  requiring it and when so affixed,
it may be  attested  by his  signature  or by the  signature  of such  Assistant
Secretary.  The  Board of  Directors  may give  general  authority  to any other
officer to affix the seal of the  Corporation  and to attest the affixing by his
signature.

         5.8 Assistant Secretary.  The Assistant Secretary,  or if there be more
than one, the  Assistant  Secretaries  in the order  determined  by the Board of
Directors  (or if there  be no such  determination,  then in the  order of their
election)  shall,  in the  absence  of the  Secretary  or in  the  event  of his
inability  or refusal to act,  perform the duties and exercise the powers of the
Secretary  and shall perform such other duties and have such other powers as the
Board of Directors may from time to time prescribe.

         5.9  Treasurer.  The Treasurer  shall have the custody of the corporate
funds and securities  and shall keep full and accurate  accounts of receipts and
disbursements in books belonging to the Corporation and shall deposit all moneys
and other valuable  effects in the name and to the credit of the  Corporation in
such  depositories  as may be  designated  by the Board of  Directors.  He shall
disburse  the  funds  of the  Corporation  as may be  ordered  by the  Board  of
Directors,  taking proper vouchers for such  disbursements,  and shall render to
the President and the Board of Directors,  at its regular meetings,  or when the
Board of Directors so requires,  an account of all his transactions as Treasurer
and of the financial condition of the Corporation.

         5.10 Assistant Treasurer. The Assistant Treasurer, or if there shall be
more than one, the Assistant  Treasurers in the order determined by the Board of
Directors  (or if there  be no such  determination,  then in the  order of their
election)  shall,  in the  absence  of the  Treasurer  or in  the  event  of his
inability  or refusal to act,  perform the duties and exercise the powers of the
Treasurer  and shall perform such other duties and have such other powers as the
Board of Directors may from time to time prescribe.

                                   ARTICLE VI

                                      Stock

         6.1  Certificates.  Every holder of stock in the  Corporation  shall be
entitled to have a certificate  signed by or in the name of the  Corporation  by
the  Chairman  or Vice  Chairman  of the  Board  of  Directors,  if any,  or the
President or a Vice President,  and by the Treasurer or an Assistant  Treasurer,
or the Secretary or an Assistant Secretary,  of the Corporation,  certifying the
number of shares owned by such holder in the Corporation. If such certificate is
manually signed by one officer or manually  countersigned by a transfer agent or
by a registrar,  any other signature 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  shall  have  ceased to be such
officer,  transfer agent or


                                      -8-


registrar before such certificate is issued, it may be issued by the Corporation
with the same  effect as if such  person were such  officer,  transfer  agent or
registrar at the date of issue.

         Upon the face or back of each stock certificate issued to represent any
partly paid shares, or upon the books and records of the Corporation in the case
of uncertificated partly paid shares, shall be set forth the total amount of the
consideration  to be paid  therefor and the amount paid thereon shall be stated.
If the Corporation  shall be authorized to issue more than one class of stock or
more than one series of any class,  the powers,  designations,  preferences  and
relative, participating, optional or other special rights of each class of stock
or series thereof and the  qualification,  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  which the Corporation  shall issue to represent such
class or series of stock, provided 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
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.

         6.2 Lost,  Stolen or  Destroyed  Stock  Certificates;  Issuance  of New
Certificates.  The Corporation may issue a new certificate of stock 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 such  owner's  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.

         6.3  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,  assignation  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 upon its books.  Upon receipt of proper transfer  instructions  from
the registered  owner of  uncertified  shares such  uncertified  shares shall be
canceled and issuance of new equivalent  uncertificated  shares or  certificated
shares shall be made to the person entitled thereto and the transaction shall be
recorded upon the books of the Corporation.

         6.4 Fixing Record Date. In order that the Corporation may determine the
stockholders  entitled to notice of or to vote at any meeting of stockholders or
any adjournment  thereof,  or to express consent to corporate  action in writing
without a meeting,  or  entitled  to receive  payment of any  dividend  or other
distribution  or allotment of any rights,  or entitled to exercise any rights in
respect of any change, conversion or exchange of stock or for the purpose of any
other lawful action,  the Board of Directors may fix, in advance, a record date,
which  shall not be more than  sixty nor less than ten days  before  the date of
such  meeting,   nor  more  than  sixty  days  prior  to  any  other  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.

         6.5  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,  and to hold liable
for  calls  and  assessments  a 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 any other person, whether or not
it shall have express or other notice thereof,  except as otherwise  provided by
the laws of Delaware.

                                   ARTICLE VII

                                  Miscellaneous

         7.1 Fiscal Year. The fiscal year of the Corporation shall be determined
by the Board of Directors.


                                      -9-


         7.2 Seal.  The  Corporation  may have a corporate seal which shall have
the name of the Corporation  inscribed  thereon and shall be in such form as may
be approved from time to time by the Board of Directors.  The corporate seal may
be used by causing it or a facsimile  thereof to be  impressed  or affixed or in
any other manner reproduced.

         7.3  Waiver  of Notice  of  Meetings  of  Stockholders,  Directors  and
Committees.  Whenever  notice  is  required  to be  given  by law or  under  any
provision of the certificate of incorporation 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
person at a meeting shall constitute a waiver of notice of such meeting,  except
when the person attends a meeting for the express  purpose of objecting,  at the
beginning of the meeting, to the transaction of any business because the meeting
is not lawfully  called or convened.  Neither the business to be transacted  at,
nor the  purpose  of,  any  regular  or  special  meeting  of the  stockholders,
directors,  or members of a committee  of  directors  need be  specified  in any
written waiver of notice unless so required by the certificate of  incorporation
or these by-laws.

         7.4 Interested  Directors;  Quorum. No contract or transaction  between
the  Corporation  and one or more of its  directors or officers,  or between the
Corporation  and  any  other  corporation,  partnership,  association  or  other
organization  in which one or more of its directors or officers are directors or
officers,  or have a financial  interest,  shall be void or voidable  solely for
this  reason,  or solely  because  the  director  or  officer  is  present at or
participates in the meeting of the Board of Directors or committee thereof which
authorizes  the contract or  transaction,  or solely because his or her or their
votes are counted for such purpose,  if: (1) the material facts as to his or her
relationship  or interest and as to the contract or transaction are disclosed or
are known to the Board of Directors or the committee, and the Board of Directors
or  committee  in good faith  authorizes  the  contract  or  transaction  by the
affirmative votes of a majority of the disinterested directors,  even though the
disinterested  directors be less than a quorum;  or (2) the material facts as to
his or her  relationship  or interest and as to the contract or transaction  are
disclosed or are known to the  stockholders  entitled to vote  thereon,  and the
contract or  transaction is  specifically  approved in good faith by vote of the
stockholders;  or (3) the contract or transaction is fair as to the  Corporation
as of  the  time  it is  authorized,  approved  or  ratified,  by the  Board  of
Directors,  a  committee  thereof  or the  stockholders.  Common  or  interested
directors may be counted in determining the presence of a quorum at a meeting of
the Board of  Directors  or of a  committee  which  authorizes  the  contract or
transaction.

         7.5 Amendment of By-Laws. These by-laws may be amended or repealed, and
new by-laws adopted, by the Board of Directors, but the stockholders entitled to
vote may adopt additional  by-laws and may amend or repeal any by-law whether or
not adopted by them.
