incorporation  or these  Bylaws  directed or required to be exercised or done by
the  stockholders.  Directors need not be stockholders or residents of the State
of Delaware.

Section 3.2 Number.  The number of directors  constituting the Board shall never
be less than one and shall be determined by resolution of the Board.

vacancies or newly-created directorships,  or to replace the directors chosen by
the directors  then in office.  No decrease in the size of the Board shall serve
to shorten the term of an incumbent director.

have been given in the notice calling such meeting.

Section 3.6  Compensation.  Unless  otherwise  restricted by the  certificate of
incorporation  or these  Bylaws,  the Board shall have the  authority to fix the
compensation of directors.  The directors may be reimbursed  their expenses,  if
any, of  attendance  at each meeting of the Board and may be paid either a fixed
sum for  attendance at each meeting of the Board or a stated salary as director.
No such payment  shall  preclude  any  director  from serving the Company in any
other capacity and receiving compensation therefor. Members of committees of the
Board may be allowed like compensation for attending committee meetings.

special  meeting  need be  specified  in the  notice or waiver of notice of such
meeting.

a quorum for the  transaction  of business at any meeting of the Board,  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,  except as may be  otherwise  specifically
provided by law, the certificate of incorporation  or these Bylaws.  If a quorum

adjourn the meeting from time to time, without notice other than announcement at

amount of the  consideration  to be paid therefor and the amount paid thereon up
to and including the time said certificate is issued.

Section  7.5 Lost  Certificates.  The  Board  may  direct a new  certificate  or
certificates   to  be  issued  in  place  of  any  certificate  or  certificates
theretofore issued by the Company alleged to have been lost, stolen or destroyed
upon  the  making  of an  affidavit  of that  fact by the  person  claiming  the
certificate  of stock to be lost,  stolen or destroyed.  When  authorizing  such
issue of a new certificate or certificates, the Board may, in its discretion and
as a condition  precedent  to the  issuance  thereof,  require the owner of such
lost,  stolen or destroyed  certificate or  certificates,  or such owner's legal
representative,  to advertise the same in such manner as it shall require and/or
to give the Company a bond in such sum as it may direct as indemnity against any

alleged to have been lost, stolen or destroyed.

Section 7.6  Transfer of Stock.  Upon  surrender  to the Company or its transfer
agent,  if any, of a  certificate  for shares duly  endorsed or  accompanied  by
proper  evidence of succession,  assignation or authority to transfer and of the
payment of all taxes  applicable  to the  transfer of said  shares,  the Company
shall be obligated to issue a new  certificate to the person  entitled  thereto,
cancel the old certificate and record the transaction upon its books;  provided,
however,  that the Company  shall not be so obligated  unless such  transfer was
made in compliance with applicable state and federal securities laws.

Section 7.7 Registered Stockholders.  The Company shall be entitled to recognize
the exclusive  right of a person  registered on its books as the owner of shares
to receive  dividends,  vote and be held  liable for calls and  assessments  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 person other than such registered owner,
whether  or not it  shall  have  express  or other  notice  thereof,  except  as
otherwise provided by law.

Article VIII

                                 INDEMNIFICATION

Section 8.1  General.  The Company  shall  indemnify  any person who was or is a
party  or is  threatened  to be  made a  party  to any  threatened,  pending  or
completed action, suit or proceeding, whether civil, criminal, administrative or
investigative  (other  than an  action by or in the  right of the  Company),  by
reason of the fact that the person is or was a  director,  officer,  employee or
agent of the  Company,  or is or was  serving at the request of the Company as a
director, officer, employee or agent of another corporation,  partnership, joint
venture,  trust or other  enterprise,  against  expenses  (including  attorneys'
fees),  judgments,  fines and amounts paid in settlement actually and reasonably
incurred by the person in connection with such action, suit or proceeding if the
person acted in good faith and in a manner the person reasonably  believed to be
in or not opposed to the best interests of the Company, and, with respect to any
criminal  action or  proceeding,  had no reasonable  cause to believe his or her
conduct was  unlawful.  The  termination  of any action,  suit or  proceeding by
judgment,  order, settlement,  conviction,  or upon a plea of nolo contendere or
its equivalent,  shall not, of itself,  create a presumption that the person did
not act in good faith and in a manner which the person reasonably believed to be
in or not opposed to the best interests of the Company, and, with respect to any
criminal action or proceeding,  have reasonable cause to believe that his or her
conduct was unlawful.

Section  8.2  Actions  by or in the  Right of the  Company.  The  Company  shall
indemnify  any person who was or is a party or is  threatened to be made a party
to any threatened, pending or completed action or suit by or in the right of the
Company to procure a judgment in its favor by reason of the fact that the person
is or was a director,  officer,  employee or agent of the Company,  or is or was
serving at the request of the Company as a director,  officer, employee or agent
of another corporation, partnership, joint venture or trust or other enterprise,
against expenses (including attorneys' fees) actually and reasonably incurred by
the person in  connection  with the defense or settlement of such action or suit
if the person acted in good faith and in a manner the person reasonably believed
to be in or not opposed to the best  interests of the Company and except that no
indemnification  shall be made in respect  of any  claim,  issue or matter as to
which such person  shall have been  adjudged to be liable to the Company  unless
and only to the  extent  that the Court of  Chancery  or the court in which such
action or suit was brought shall determine upon  application  that,  despite the
adjudication of liability but in view of all the circumstances of the case, such
person is fairly and  reasonably  entitled to indemnity for such expenses  which
the Court of Chancery or such other court shall deem proper.

Section 8.3  Indemnification  Against Expenses.  To the extent that a present or
former  director or officer of the Company has been  successful on the merits or
otherwise in defense of any action,  suit or proceeding  referred to in Sections
8.1 and 8.2 hereof,  or in defense of any claim,  issue or matter therein,  such
person  shall  be  indemnified  against  expenses  (including  attorneys'  fees)
actually and reasonably incurred by such person in connection therewith.

Section 8.4 Board Determinations. Any indemnification under Sections 8.1 and 8.2
hereof  (unless  ordered  by a  court)  shall  be  made by the  Company  only as
authorized in the specific case upon a determination that indemnification of the
present  or  former  director,  officer,  employee  or  agent is  proper  in the
circumstances  because the person has met the applicable standard of conduct set
forth in Sections 8.1 and 8.2 hereof.  Such  determination  shall be made,  with
respect  to a  person  who  is a  director  or  officer  at  the  time  of  such
determination,  (1) by a majority  vote of the directors who were not parties to
such action,  suit or  proceeding,  even though less than a quorum,  or (2) by a
committee of such directors designated by majority vote of such directors,  even
though less than a quorum, or (3) if there are no such  disinterested  directors
or if such  directors  so  direct,  by  independent  legal  counsel in a written
opinion, or (4) by the stockholders.

Section 8.5 Advancement of Expenses. Expenses including attorneys' fees incurred
by an officer or director  in  defending  a civil or  criminal  action,  suit or
proceeding  may be paid by the  Company in advance of the final  disposition  of
such action,  suit or proceeding  upon receipt of an undertaking by or on behalf
of such  director  or  officer to repay such  amount if it shall  ultimately  be
determined  that such person is not entitled to be indemnified by the Company as
authorized by law or in this section. Such expenses incurred by former directors
and  officers or other  employees  and agents may be so paid upon such terms and
conditions, if any, as the Company deems appropriate.

Section  8.6  Nonexclusive.  The  indemnification  and  advancement  of expenses
provided by, or granted  pursuant to, this section shall not be deemed exclusive
of any other  rights to which any  director,  officer,  employee or agent of the
Company seeking indemnification or advancement of expenses may be entitled under
any other bylaw,  agreement,  vote of stockholders or disinterested directors or
otherwise, both as to action in such person's official capacity and as to action
in another  capacity  while  holding such office,  and shall,  unless  otherwise
provided when authorized or ratified,  continue as to a person who has ceased to
be a director,  officer, employee or agent of the Company and shall inure to the
benefit of the heirs, executors and administrators of such a person.

Section 8.7 Insurance. The Company may purchase and maintain insurance on behalf
of any  person  who is or was a  director,  officer,  employee  or  agent of the
Company,  or is or was  serving  at the  request of the  Company as a  director,
officer, employee or agent of another corporation,  partnership,  joint venture,
trust or other  enterprise,  against any liability  asserted against such person
and incurred by such person in any such capacity or arising out of such person's
status as such,  whether or not the  Company  would have the power to  indemnify
such person against such liability under the provisions of applicable  statutes,
the certificate of incorporation or this section.

Section 8.8 Certain Definitions.  For purposes of this Section 8, (a) references
to "the Company" shall include,  in addition to the resulting  corporation,  any
constituent corporation (including any constituent of a constituent) absorbed in
a consolidation or merger that, if its separate  existence had continued,  would
have had power and authority to indemnify its directors,  officers and employees
or agents,  so that any person who is or was a  director,  officer,  employee or
agent of such  constituent  corporation,  or is or was serving at the request of
such  constituent  corporation  as a  director,  officer,  employee  or agent of
another  corporation,  partnership,  joint venture,  trust or other  enterprise,
shall stand in the same  position  under the  provisions  of this  section  with
respect to the resulting or surviving corporation as such person would have with
respect to such constituent corporation if its separate existence had continued;
(b)  references to "fines"  shall include any excise taxes  assessed on a person
with respect to an employee  benefit plan; and (c) references to "serving at the
request of the  Company"  shall  include  any  service as a  director,  officer,
employee or agent of the Company  that imposes  duties on, or involves  services
by,  such  director,  officer,  employee or agent with  respect to any  employee
benefit plan, its participants, or beneficiaries; and a person who acted in good
faith and in a manner such person  reasonably  believed to be in the interest of
the participants  and  beneficiaries of an employee benefit plan shall be deemed
to have acted in a manner "not opposed to the best  interests of the Company" as
referred to in this section.

Section 8.9 Change in Governing  Law. In the event of any  amendment or addition
to Section  145 of the General  Corporation  Law of the State of Delaware or the
addition  of any other  section to such law that limits  indemnification  rights
thereunder,   the  Company  shall,  to  the  extent  permitted  by  the  General
Corporation  Law of the  State of  Delaware,  indemnify  to the  fullest  extent
authorized  or  permitted  hereunder,  any  person  who was or is a party  or is
threatened to be made a party to any  threatened,  pending or completed  action,
suit or proceeding,  whether civil,  criminal,  administrative  or investigative
(including an action by or in the right of the  Company),  by reason of the fact
that he or she is or was a director,  officer, employee or agent of the Company,
or is or was  serving at the  request of the  Company  as a  director,  officer,
employee or agent of another corporation,  partnership,  joint venture, trust or
other enterprise, against expenses (including attorneys' fees), judgments, fines
and amounts paid in settlement actually and reasonably incurred by him or her in
connection with such action, suit or proceeding.

any of its directors,  officers or  stockholders  (or any corporation or firm in
which any of them are directly or indirectly  interested) shall be valid for all

at  the  meeting  authorizing  such  contract  or  transaction,  or  his  or her

         the contract or  transaction  by a majority of the  directors  present,
         each such  interested  director to be counted in determining  whether a
         quorum is present but not in  calculating  the  majority  necessary  to
         carry the vote; or

(B)      to the  stockholders  and they  nevertheless in good faith authorize or
         ratify the contract or transaction by a majority of the shares present,
         each such  interested  person  to be  counted  for  quorum  and  voting
         purposes.

Section 9.3  Nonexclusive.  This provision  shall not be construed to invalidate

meetings  shall be held at such place or places,  within or without the State of

Section 10.2      Fixing Record Dates.
                  -------------------

(a)  In order that the Company may determine the stockholders entitled to notice
     of or to vote at any meeting of stockholders  or any  adjournment  thereof,
     the Board may fix, in advance,  a record date,  which shall not precede the
     date upon which the  resolution  fixing  the record  date is adopted by the
     Board, and which record date shall not be more than sixty nor less than ten
     days prior to any such action. If no record date is fixed by the Board, 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  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. 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 may fix a new record date for
     the adjourned meeting.

(b)  In order that the  Company  may  determine  the  stockholders  entitled  to
     consent to corporate action in writing without a meeting, the Board may fix
     a record date,  which record date shall not precede the date upon which the
     resolution  fixing the record date is adopted by the Board,  and which date
     shall not be more than ten days  after the date upon  which the  resolution
     fixing the record date is adopted by the Board.  If no record date has been
     fixed by the Board, the record date for determining  stockholders  entitled
     to consent to corporate action in writing without a meeting,  when no prior
     action by the Board is otherwise required, 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 Company by delivery to its  registered  office in
     the State of Delaware,  its principal  place of business,  or an officer or
     agent of the Company  having  custody of the book in which  proceedings  of
     meetings of  stockholders  are  recorded.  Delivery  made to the  Company's
     registered  office  shall be by hand or by certified  or  registered  mail,
     return receipt requested. If no record date has been fixed by the Board and
     prior  action by the Board is  required,  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 day on which the Board
     adopts the resolution taking such prior action.

(c)  In order that the  Company  may  determine  the  stockholders  entitled  to
     receive  payment of any dividend or other  distribution or allotment of any
     rights or the  stockholders  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 may fix a record  date,  which record date
     shall not precede the date upon which the resolution fixing the record date
     is adopted,  and which  record date shall be not more than sixty days prior
     to such action. If no record date is fixed, the record date for determining
     stockholders  for any such purpose shall be at the close of business on the
     day on which the Board adopts the resolution relating thereto.

Section  10.3  Means of  Giving  Notice.  Whenever  under  applicable  law,  the

any director or  stockholder,  such notice may be given in writing and delivered
personally,  through the United  States mail, by a recognized  express  delivery
service  (such as Federal  Express) or by means of telegram,  telex or facsimile
transmission, addressed to such director or stockholder at his or her address or
telex or facsimile  transmission  number,  as the case may be,  appearing on the

States mail or with an express delivery service or when transmitted, as the case
may be.  Notice  of any  meeting  of the  Board  may be given to a  director  by
telephone  and  shall  be  deemed  to be given  when  actually  received  by the
director.

applicable  law, the  certificate of  incorporation  or these Bylaws,  a written
waiver of such  notice,  signed  before or after the date of such meeting by the
person or persons  entitled to said notice,  shall be deemed  equivalent to such
required  notice.  All such waivers shall be filed with the  corporate  records.
Attendance  at a meeting  shall  constitute a waiver of notice of such  meeting,
except  where a person  attends  for the  express  purpose of  objecting  to the
transaction  of any  business  on the ground  that the  meeting is not  lawfully
called or convened.

Section  10.5  Attendance  via   Communications   Equipment.   Unless  otherwise
restricted by applicable law, the certificate of  incorporation or these Bylaws,

meeting by means of conference  telephone or other  communications  equipment by
means  of  which  all  persons  participating  in the  meeting  can  effectively
communicate  with each other.  Such  participation in a meeting shall constitute

meeting for the express  purpose of objecting to the transaction of any business
on the ground that the meeting is not lawfully called or convened.

Section 10.6 Dividends.  Dividends on the capital stock of the Company,  paid in
cash,  property or securities of the Company and as may be limited by applicable

Section 10.7 Reserves.  Before  payment of any dividend,  there may be set aside
out of any funds of the Company  available for dividends such sum or sums as the
Board from time to time,  in its  absolute  discretion,  determines  proper as a
reserve  or  reserves  to meet  contingencies,  for  equalizing  dividends,  for
repairing or  maintaining  any property of the Company or for such other purpose
as the Board shall determine to be in the best interest of the Company;  and the
Board may  modify or  abolish  any such  reserve  in the  manner in which it was
created.

Section 10.8  Reports to  Stockholders.  The Board shall  present at each annual
meeting of stockholders,  and at any special meeting of stockholders when called
for by vote of the  stockholders,  a statement of the business and  condition of

by applicable law or these Bylaws, any contract or other instrument  relative to
the  business of the Company may be executed  and  delivered  in the name of the

Board may  authorize any other officer or agent of the Company to enter into any
contract or execute  and  deliver any  contract in the name and on behalf of the
Company,  and such authority may be general or confined to specific instances as
the  Board  may by  resolution  determine.  All  bills,  notes,  checks or other

officer,  officers, agent or agents and in such manner as are permitted by these
Bylaws and/or as, from time to time,  may be  prescribed by resolution  (whether
general or special) of the Board.  Unless authorized so to do by these Bylaws or
by the Board, no officer, agent or employee shall have any power or authority to
bind the Company by any contract or engagement,  or to pledge its credit,  or to
render it liable pecuniarily for any purpose or to any amount.
