When a  determination  of  Stockholders  entitled to notice of or to vote at any
meeting of  Stockholders  has been made as provided in this  Section  2.5,  such
determination  shall apply to any  adjournment  thereof unless the Board fixes a
new record date for the adjourned meeting.

                  Delivery  made  to  the  Corporation's  registered  office  in
accordance  with Section  2.5.2 shall be by hand or by  certified or  registered
mail, return receipt requested.

                  2.6 NOTICE OF MEETINGS OF  STOCKHOLDERS.  Except as  otherwise
provided in Section 2.7 hereof,  whenever  under the  provisions of any statute,
the Certificate of Incorporation  or these Bylaws,  Stockholders are required or
permitted to take any action at a meeting, written notice shall be given stating
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.  Unless  otherwise
provided by any statute,  the Certificate of Incorporation  or these By-laws,  a
copy of the notice of any meeting  shall be given,  personally  or by mail,  not
less than ten nor more than sixty days before the date of the  meeting,  to each
Stockholder  entitled to notice of or to vote at such meeting.  If mailed,  such
notice  shall be deemed to be given when  deposited  in the United  States mail,
with postage  prepaid,  directed to the  Stockholder at his or her 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
required by this Section 2.6 has been given shall,  in the absence of fraud,  be
prima facie evidence of the facts stated therein. When a meeting is adjourned to
another time or place,  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,  and at the adjourned  meeting any business may be transacted  that might
have been  transacted  at the meeting as originally  called.  If,  however,  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.

                  2.7  WAIVERS OF NOTICE.  Whenever  the giving of any notice is
required by statute,  the Certificate of Incorporation or these Bylaws, a waiver
thereof, in writing,  signed by the Stockholder or Stockholders entitled to said
notice,  whether  before or after the event as to which such notice is required,
shall be deemed  equivalent to notice.  Attendance by a Stockholder at a meeting
shall  constitute a waiver of notice of such meeting except when the Stockholder
attends a meeting for the express purpose of objecting,  at the beginning of the
meeting,  to the  transaction of any business on the ground that the meeting has
not been lawfully called or convened.

                  2.8 LIST OF  STOCKHOLDERS.  The  Secretary  shall  prepare and
make,  or cause to be prepared and made,  at least ten days before every meeting
of  Stockholders,  a complete list of the  Stockholders  entitled to vote at the
meeting,  arranged  in  alphabetical  




                                                                               6

order,  and  showing the  address of each  Stockholder  and the number of shares
registered in the name of each  Stockholder.  If any voting group  exists,  such
list shall be arranged by voting group and within each voting group by series or
class of shares.  Such list shall be open to the examination of any Stockholder,
the  Stockholder's  agent or attorney,  at the  Stockholder's  expense,  for any
purpose germane to the meeting,  during ordinary business hours, for a period of
at least ten 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. The Corporation shall maintain the list of Stockholders in written form
or in another form capable of  conversion  into written form within a reasonable
time.  Upon the willful  neglect or refusal of the  Directors  to produce such a
list at any meeting for the election of Directors,  they shall be ineligible for
election  to any  office at such  meeting.  The stock  ledger  shall be the only
evidence as to who are the  Stockholders  entitled to examine the stock  ledger,
the list of Stockholders or the books of the  Corporation,  or to vote in person
or by proxy at any meeting of Stockholders.

                  2.9 QUORUM OF STOCKHOLDERS;  ADJOURNMENT.  Except as otherwise
provided by any statute,  the Certificate of Incorporation or these Bylaws,  the
holders of a majority of all outstanding shares of stock entitled to vote at any
meeting  of  Stockholders,  present  in person or  represented  by proxy,  shall
constitute a quorum for the transaction of any business at such meeting.  When a
quorum is once present to organize a meeting of  Stockholders,  it is not broken
by the subsequent  withdrawal of any Stockholders.  The holders of a majority of
the shares of stock present in person or  represented by proxy at any meeting of
Stockholders,  including  an  adjourned  meeting,  whether  or not a  quorum  is
present,  may adjourn such meeting to another time and place.  Shares of its own
stock belonging to 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.

                  2.10  VOTING;   PROXIES.  Unless  otherwise  provided  in  the
Certificate of  Incorporation,  every Stockholder of record shall be entitled at
every  meeting  of  Stockholders  to one vote for each  share of  capital  stock
standing  in  his or her  name  on the  record  of  Stockholders  determined  in
accordance with Section 2.5 hereof. If the Certificate of Incorporation provides
for more or less than one vote for any share on any matter,  each  reference  in
the Bylaws or the General  Corporation Law to a majority or other  proportion of
stock shall  refer to such  majority  or other  proportion  of the votes of such
stock.  The  provisions of Sections 212 and 217 of the General  Corporation  Law
shall apply in determining  whether any shares of capital stock may be voted and
the persons,  if any, entitled to vote such shares; but the Corporation shall be
protected in 




                                                                               7


assuming  that the persons in whose names  shares of capital  stock stand on the
stock ledger of the  Corporation  are  entitled to vote such shares.  Holders of
redeemable  shares  of stock  are not  entitled  to vote  after  the  notice  of
redemption  is mailed to such holders and a sum  sufficient to redeem the stocks
has been deposited with a bank,  trust company,  or other financial  institution
under an  irrevocable  obligation  to pay the  holders the  redemption  price on
surrender  of the shares of stock.  At any meeting of  Stockholders  (at which a
quorum was present to organize the  meeting),  all matters,  except as otherwise
provided by statute or by the Certificate of  Incorporation  or by these Bylaws,
shall be decided by a majority of the votes cast at such  meeting by the holders
of shares  present  in  person or  represented  by proxy  and  entitled  to vote
thereon,  whether  or not a quorum is  present  when the vote is taken.  Where a
separate  vote by a class or  classes  of  stock is  required  by  statute,  the
Certificate  of  Incorporation  or these Bylaws,  a majority of the  outstanding
shares of such class or classes  present in person or represented by proxy shall
constitute  a quorum  entitled to take action with  respect to that vote on that
matter,  and such  matter  shall be decided  by a majority  of the votes of such
class or  classes  present  in person or  represented  by proxy at the  meeting.
Directors may be elected either by written ballot or by voice vote. In voting on
any other  question  on which a vote by ballot is required by law or is demanded
by any Stockholder  entitled to vote, the voting shall be by ballot. Each ballot
shall be signed by the Stockholder  voting or the Stockholder's  proxy and shall
state the number of shares voted. On all other  questions,  the voting may be by
voice vote. Each  Stockholder  entitled to vote at a meeting of Stockholders may
authorize  another person or persons to act for such  Stockholder by proxy.  The
validity and  enforceability of any proxy shall be determined in accordance with
Section 212 of the General  Corporation  Law. A Stockholder may revoke any proxy
that is not  irrevocable  by  attending  the  meeting and voting in person or by
filing an instrument  in writing  revoking the proxy or by delivering a proxy in
accordance with applicable law bearing a later date to the Secretary.

                  2.11 VOTING  PROCEDURES AND INSPECTORS OF ELECTION AT MEETINGS
OF  STOCKHOLDERs.  The  Corporation,  in advance of any meeting of Stockholders,
shall  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, the person presiding at the meeting shall
appoint,  one or more inspectors to act at the meeting.  Each inspector,  before
entering  upon the  discharge of his or her duties,  shall take and sign an oath
faithfully  to execute  the duties of  inspector  with strict  impartiality  and
according to the best of his or her ability.  The inspectors shall (a) ascertain
the number of shares outstanding and the voting power of each, (b) determine the
shares  represented at the meeting and the validity of proxies and ballots,  (c)
count all votes and ballots,  (d) determine and retain for a reasonable period a
record of the  disposition of any challenges  made to any  determination  by the
inspectors,  and  (e)  certify  their  determination  of the  number  of  shares
represented  at the  meeting  and  their  count of all votes  and  ballots.  The
inspectors  may  appoint  or retain  other  persons  or  entities  to assist the
inspectors in the performance of their duties.  The date and time of the opening
and 





                                                                               8

the closing of the polls for each matter upon which the  Stockholders  will vote
at a meeting  shall be  determined  by the person  presiding  at the meeting and
shall  be  announced  at the  meeting.  No  ballot,  proxies  or  votes,  or any
revocation thereof or change thereto,  shall be accepted by the inspectors after
the  closing of the polls  unless the Court of Chancery of the State of Delaware
upon application by a Stockholder shall determine otherwise.

                  2.12 CONDUCT OF MEETINGS. (a) At each meeting of Stockholders,
the President, or in the absence of the President,  the Chairman, or if there is
no Chairman or if there be one and the  Chairman is absent,  an  Executive  Vice
President,  and in case more than one Executive Vice President shall be present,
that Executive Vice President  designated by the Board (or in the absence of any
such designation, in the order of their first election, present), or it there is
no Executive  Vice President or if there be one and the Executive Vice President
is absent,  a Vice President,  and in case more than one Vice President shall be
present,  that Vice President  designated by the Board (or in the absence of any
such designation,  in the order of their first election,  present), shall act as
chairman  of the  meeting.  The  Secretary,  or in his or her absence one of the
Assistant  Secretaries,  shall act as secretary of the meeting.  In case none of
the officers  above  designated  to act as chairman or secretary of the meeting,
respectively, shall be present, a chairman or a secretary of the meeting, as the
case may be,  shall be chosen by a majority of the votes cast at such meeting by
the holders of shares of capital stock present in person or represented by proxy
and entitled to vote at the meeting.

                  2.13 ORDER OF BUSINESS.  The order of business at all meetings
of Stockholders  shall be as determined by the chairman of the meeting,  but the
order of business to be followed at any meeting at which a quorum is present may
be  changed by a majority  of the votes cast at such  meeting by the  holders of
shares of capital stock present in person or  represented  by proxy and entitled
to vote at the meeting.

                  2.14 WRITTEN CONSENT OF STOCKHOLDERS WITHOUT A MEETING. Unless
otherwise  provided in the Certificate of Incorporation,  any action required or
permitted  by the General  Corporation  Law 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  (by hand or by certified or  registered  mail,
return  receipt  requested)  to the  Corporation  by delivery to its  registered
office in the State of Delaware,  its principal place of business, or an officer
or agent of the Corporation  having custody of the book in which  proceedings of
meetings of stockholders are recorded. 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 60 days of the earliest dated consent delivered in the manner required by
this  Section  2.14,   written  consents  signed  by  a  




                                                                               9

sufficient   number  of  Stockholders  to  take  action  are  delivered  to  the
Corporation  as aforesaid.  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 and who, if the action had been
taken at a meeting,  would have been  entitled  to notice of the  meeting if the
record date for such meeting had been the date that written consents signed by a
sufficient  number of  Stockholders  to take the action  were  delivered  to the
Corporation as aforesaid.

the Entire Board then in office, whether or not present at a meeting.  Directors
need not be Stockholders. The Directors shall be divided into three classes with

Stockholders  of the  Corporation  next  following the end of the  Corporation's
fiscal year ending  December 31, 2000.  At each annual  meeting of  Stockholders

those  Directors  whose  terms  expire  shall be elected for a term of office to
expire at the third  succeeding  annual  meeting  of  Stockholders  after  their

term of any director who is also an officer of the  Corporation  shall terminate
if he or she ceases to be an officer of the Corporation.

                  3.4 ELECTION. Directors shall, except as otherwise required by
statute or by the Certificate of Incorporation, be elected by a plurality of the
votes  cast at a meeting of  Stockholders  by the  holders of shares  present in
person  or  represented  by proxy at the  meeting  and  entitled  to vote in the
election.

                  3.5 NEWLY CREATED DIRECTORSHIPS AND VACANCIES.  Subject to the
rights of the holders of any series of preferred stock of the  Corporation  then
outstanding,  newly  created  directorships  resulting  from any increase in the
authorized  number of Directors or any  vacancies  in the Board  resulting  from
death, resignation, retirement,  disqualification,  removal from office or other
cause  shall be filled by a majority  vote of the  remaining  Directors  then in
office  although  less  than a  quorum,  or by a  sole  remaining  Director  and
Directors so chosen shall hold office for a term expiring at the annual  meeting
of  stockholders  at which the term of the class to which they have been elected
expires or, in each case, until their respective successors are duly elected and
qualified.  No decrease in the number of Directors  constituting the Board shall
shorten the term of any incumbent Director.  When any Director shall give notice
of  resignation  effective at a future date,  the Board may fill such vacancy to
take effect when such resignation shall become effective.

                  3.6  RESIGNATION.  Any  Director  may  resign  at any  time by
written notice to the  Corporation.  Such  resignation  shall take effect at the
time therein specified, and, unless otherwise specified in such resignation, the
acceptance of such resignation shall not be necessary to make it effective.

                  3.7 REMOVAL.  Any one or more or all of the  Directors  may be
removed,  at any time, but only for cause by the Stockholders  having at least a
majority in voting  power of the then issued and  outstanding  shares of capital
stock of the  Corporation.  If pursuant to the  Certificate of  Incorporation  a
Director is elected by a voting group of Stockholders,  only the Stockholders of
the voting group may participate in the vote to remove such Director.

                  3.8  COMPENSATION.  Each Director,  in consideration of his or
her service as such, may receive from the  Corporation  such amount per annum or
such fees for attendance at Directors' meetings,  or both, as the Board may from
time  to  time  determine,   together  with  reimbursement  for  the  reasonable
out-of-pocket expenses, if any, incurred by such Director in connection with the
performance  of his or her duties.  Each Director who shall serve as a member of
any committee of Directors in  consideration of serving as such may receive such
additional  amount per annum or such fees for attendance at committee  meetings,
or  both,  as  the  Board  may  from  time  to  time  determine,  together  with
reimbursement  for the reasonable  out-of-pocket  expenses,  if any, incurred by

both regular and special,  either  within or without the State of Delaware.  The
times and places  for  holding  meetings  of the Board may be fixed from time to
time by  resolution  of the Board or (unless  contrary  to a  resolution  of the
Board) in the notice of the meeting.

                  3.10 ANNUAL  MEETINGS.  On the day when and at the place where
the annual meeting of Stockholders for the election of Directors is held, and as
soon as practicable thereafter,  the Board may hold its annual meeting,  without
notice of such meeting,  provided a quorum shall be present, for the purposes of
organization,  the election of officers and the  transaction of other  business.
The  annual  meeting  of the  Board  may be held at any  other  time  and  place
specified  in a notice  given as  provided  in Section  3.12  hereof for special
meetings of the Board or in a waiver of notice thereof.

                  3.11 REGULAR  MEETINGS.  Regular  meetings of the Board may be
held without  notice at such times and at such places as shall from time to time
be determined by the Board.

called by the  President  or any  Director  then  serving  on at least one day's
notice to each  Director  given by one of the means  specified  in Section  3.15
hereof other than by mail, or on at least three days' notice if given by mail.

designated  by the Board may  participate  in a meeting  of the Board or of such
committee by means of conference telephone or similar  communications  equipment
by means of which all persons  participating in the meeting can hear each other,
and  participation  in a meeting  pursuant to this Section 3.13 shall constitute
presence in person at such meeting.

                  3.14 ADJOURNED  MEETINGS.  A majority of the Directors present
at any meeting of the Board,  including an adjourned  meeting,  whether or not a
quorum is present,  may adjourn such meeting to another time and place. At least
one day's  notice of any  adjourned  meeting of the Board shall be given to each
Director whether or not present at the time of the  adjournment,  if such notice
shall be given by one of the means  specified  in Section 3.15 hereof other than

meeting as originally called.

                  3.15  NOTICE  PROCEDURE.  Subject  to  Sections  3.13 and 3.16
hereof,  whenever,  under the  provisions  of any statute,  the  Certificate  of

telephone,  by mail addressed to such Director at such 




                                                                              12

required by statute,  the Certificate of Incorporation or these Bylaws, a waiver
thereof,  in writing,  signed by the person or persons  entitled to said notice,
whether before or after the event as to which such notice is required,  shall be
deemed  equivalent  to  notice.  Attendance  by  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 on the ground that the meeting has not been
lawfully  called or convened.  Neither the business to be transacted at, nor the
purpose of, any regular or special  meeting of the  Directors  or a committee of
Directors  need be specified in any written  waiver of notice unless so required
by statute, the Certificate of Incorporation or these Bylaws.

                  3.17 ORGANIZATION. At each meeting of the Board, the Chairman,
or in the  absence of the  Chairman,  the  President,  or in the  absence of the
President,  a chairman  chosen by a majority  of the  Directors  present,  shall

case the Secretary  shall be absent from any meeting of the Board,  an Assistant
Secretary  shall  perform the duties of  secretary at such  meeting;  and in the
absence from any such meeting of the Secretary  and all  Assistant  Secretaries,
the person  presiding  at the meeting may appoint any person to act as secretary
of the meeting.

                  3.18  QUORUM  OF  DIRECTORS.  Except  as  otherwise  expressly
provided by statute or the Certificate of Incorporation,  the presence in person
of a  majority  of the  Entire  Board  shall  be  necessary  and  sufficient  to
constitute a quorum for the transaction of business at any meeting of the Board,
but a majority of a smaller number may adjourn any such meeting to a later date.

                  3.19 ACTION BY MAJORITY  VOTE.  Except as otherwise  expressly
required by statute,  the Certificate of Incorporation or these Bylaws,  the act
of a majority of the Directors present at a meeting at which a quorum is present
shall be the act of the Board.

                  3.20 ACTION WITHOUT 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 or of any  committee  thereof

                             COMMITTEES OF THE BOARD
                             -----------------------

                  The Board,  by resolution  adopted by a majority of the Entire
Board, may designate one or more committees, 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 such committee. If a member of a committee
shall be absent from any  meeting,  or  disqualified  from voting  thereat,  the
remaining member or members present and not disqualified from voting, whether or
not such  member or members  constitute  a quorum,  may,  by a  unanimous  vote,
appoint  another  member of the Board 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 or these Bylaws,  shall have and may exercise all
the powers and  authority  of the Board in the  management  of the  business and
affairs of the Corporation,  and may authorize the seal of the Corporation to be
impressed  on all papers that may require it, but no such  committee  shall have
the  power or  authority  of the  Board  in  reference  to:  (i)  approving,  or
recommending  to  the  Stockholders,   any  action  that  the  Delaware  General
Corporation  Law  requires  to be  approved by the  Stockholders;  (ii)  filling
vacancies  on  the  Board  or on  any  of its  committees;  (iii)  amending  the
Certificate  of  Incorporation;  (iv)  adopting,  amending,  or repealing  these
Bylaws;   (v)  approving  a  plan  of  merger  not  requiring  approval  of  the
Stockholders; (vi) authorizing or approving a distribution,  except according to
a general  formula or method  prescribed by the Board;  or (vii)  authorizing or
approving the issuance or sale or contract for sale of shares,  or determine the
designation  and relative  rights,  preferences,  and  limitations of a class or
series of shares,  except that the Board may authorize a committee,  or a senior
executive  officer  of the  Corporation,  to do so  within  limits  specifically
prescribed by the Board.  Unless  otherwise  specified in the  resolution of the
Board  designating a committee,  at all meetings of such committee a majority of
the total number of members of the committee  shall  constitute a quorum for the
transaction  of  business,  and the vote of a  majority  of the  members  of the
committee  present at any meeting at which there is a quorum shall be the act of
the  committee.  Each committee  shall keep regular  minutes of its meetings and
report the same to the Board when required. Unless the Board otherwise provides,
each committee  designated by the Board may make, alter and repeal rules for the
conduct of its  business.  In the  absence of such  rules each  committee  shall
conduct  its  business  in the same manner as the Board  conducts  its  business
pursuant to Article 3 of these Bylaws.

                                                                              14

more Assistant  Secretaries  and Assistant  Treasurers,  who shall exercise such

effective.  The  resignation  of an officer  shall be without  prejudice  to the
contract rights of the Corporation,  if any. Any officer elected or appointed by
the Board  may be  removed  at any time,  with or  without  cause,  by vote of a
majority  of the  Entire  Board.  Any  vacancy  occurring  in any  office of the
Corporation  shall be filled by the Board.  The  removal  of an officer  without
cause shall be without  prejudice to the officer's  contract rights, if any. The
election  or  appointment  of an  officer  shall not of itself  create  contract
rights.

                  5.5 FIDELITY BONDS.  The Corporation may secure the fidelity 
of any or all of its officers or agents by bond or otherwise.

                  5.6 CHAIRMAN.  The Chairman  shall exercise such duties as are

stock of the  Corporation  shall be  represented  by  certificates  in such form
(consistent  with the provisions of Section 158 of the General  Corporation Law)
as shall be  approved  by the Board.  Such  certificates  shall be signed by the
Chairman, the President,  an Executive Vice President or a Vice President and by
the  Secretary  or an  Assistant  Secretary  or the  Treasurer  or an  Assistant

any  officer,  transfer  agent or  registrar  who has signed or whose  facsimile
signature  has been  placed  upon any  certificate  shall have ceased to be such
officer,  transfer agent or registrar  before such  certificate is issued,  such
certificate  may,  unless  otherwise  ordered  by the  Board,  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.

of the  Corporation  shall be made only on the books of the  Corporation  by the
holder thereof or by the holder's duly authorized  attorney appointed by a power
of attorney duly  executed and filed with the  Secretary or a transfer  agent of
the   Corporation,   and  on  surrender  of  the   certificate  or  certificates
representing  such shares of capital  stock  properly  endorsed for transfer and
upon payment of all  necessary  transfer  taxes.  Every  certificate  exchanged,
returned or surrendered to the Corporation shall be marked  "Canceled," with the
date of cancellation, by the Secretary or an Assistant Secretary or the transfer
agent of the  Corporation.  A person in whose name shares of capital stock shall
stand on the books of the  Corporation  shall be deemed  the  owner  thereof  to
receive dividends,  to vote as such owner and for all other purposes as respects
the  Corporation.  No  transfer  of shares of  capital  stock  shall be valid as
against the Corporation,  its Stockholders and creditors for any purpose, except
to render the transferee  liable for the debts of the  Corporation to the extent
provided by law, until such transfer shall have been entered on the books of the
Corporation by an entry showing from and to whom transferred.

                  7.3 TRANSFER AND REGISTRY  AGENTS.  The  Corporation  may from
time to time  maintain  one or more  transfer  offices  or agents  and  registry
offices or agents at such place or places as may be determined from time to time
by the Board.

                  7.4 LOST, DESTROYED,  STOLEN AND MUTILATED  CERTIFICATES.  The
holder of any  shares of  capital  stock of the  Corporation  shall  immediately
notify the  Corporation  of any loss,  destruction,  theft or  mutilation of the
certificate  representing  such  shares,  and the  Corporation  may  issue a new
certificate  to replace the  certificate  alleged to have been lost,  destroyed,
stolen or  mutilated.  The Board may, in its  discretion,  as a condition to the
issue of any such new  certificate,  require  the owner of the lost,  destroyed,
stolen or mutilated certificate,  or his or her legal  representatives,  to make
proof satisfactory to the Board of such loss,  destruction,  theft or mutilation
and to advertise such fact in such manner as the Board may require,  and to give
the Corporation  and its transfer agents and registrars,  or such of them as the
Board may  require,  a bond in such form,  in such sums and with such  surety or
sureties as the Board may direct,  to indemnify the Corporation and its transfer
agents and registrars  against any claim that may be made against any of them on
account of the continued  existence of any such  certificate  so alleged to have
been lost, destroyed,  stolen or mutilated and against any expense in connection
with such claim.

                  7.5 RULES AND  REGULATIONS.  The Board may make such rules and
regulations as it may deem expedient, not inconsistent with these Bylaws or with
the   Certificate  of   Incorporation,   concerning  the  issue,   transfer  and
registration of certificates representing shares of its capital stock.

                  7.6 RESTRICTION ON TRANSFER OF STOCK. A written restriction on
the transfer or registration of transfer of capital stock of the Corporation, if
permitted by Section 202 of the General  Corporation Law and noted conspicuously
on the certificate 




                                                                              19

representing  such  capital  stock,  may be  enforced  against the holder of the
restricted capital stock or any successor or transferee of the holder, including
an executor, administrator,  trustee, guardian or other fiduciary entrusted with
like  responsibility  for the  person  or  estate of the  holder.  Unless  noted
conspicuously on the certificate representing such capital stock, a restriction,
even though  permitted by Section 202 of the General  Corporation  Law, shall be
ineffective except against a person with actual knowledge of the restriction.  A
restriction on the transfer or  registration of transfer of capital stock of the
Corporation may be imposed either by the Certificate of  Incorporation  or by an
agreement among any number of Stockholders  or among such  Stockholders  and the
Corporation.  No restriction so imposed shall be binding with respect to capital
stock issued prior to the adoption of the restriction unless the holders of such
capital stock are parties to an agreement or voted in favor of the restriction.

                  7.7  DIVIDENDS, SURPLUS, ETC.  Subject to the provisions of
the Certificate of Incorporation and of law, the Board:

                                    7.7.1   may declare and pay dividends or
          make other distributions on the outstanding shares of capital stock in
          such amounts and at such time or times as it, in its discretion, shall
          deem  advisable  giving  due  consideration  to the  condition  of the
          affairs of the Corporation;

                                    7.7.2  may use and apply, in its discretion,
          any of the surplus of the  Corporation  in purchasing or acquiring any
          shares of  capital  stock of the  Corporation,  or  purchase  warrants
          therefor,  in  accordance  with law, or any of its bonds,  debentures,
          notes, scrip or other securities or evidences of indebtedness; and

                                    7.7.3 may set aside from time to time out of
          such surplus or net profits such sum or sums as, in its discretion, it
          may think  proper,  as a reserve  fund to meet  contingencies,  or for
          equalizing  dividends or for the purpose of  maintaining or increasing
          the property or business of the Corporation, or for any purpose it may
          think conducive to the best interests of the Corporation.

any one of the following  officers:  Chairman,  President,  any  Executive  Vice
President,  any Vice President,  Secretary, or Treasurer,  may call a meeting of

Notwithstanding the foregoing, no meeting of the Board shall take place pursuant
