the  holders of a  majority  of the  shares of common  stock of the  Corporation
present and entitled to vote at a duly convened  meeting of the  stockholders of
the Corporation.

                                   ARTICLE IX
                                 INDEMNIFICATION

     SECTION 1. A director of the Corporation  shall not be personally liable to
the Corporation or its stockholders for monetary damages for breach of fiduciary
duty as a director,  except for liability  (i) for any breach of the  director's
duty  of  loyalty to  the Corporation or  its stockholders, (ii) for  acts  or

                                       9
<PAGE>
omissions not in good faith or which involve intentional misconduct or a knowing
violation of law,  (iii) under Section 174 of the Delaware  General  Corporation
Law, or (iv) for any  transaction  from which the  director  derived an improper
personal benefit.

     SECTION 2. Each  person who has or is made a party or is  threatened  to be
made a party to or is involved in any action, suit or proceeding, whether civil,
criminal,  administrative  or  investigative  (hereinafter a  "proceeding"),  by
reason  of the fact  that he or she,  or a person of whom he or she is the legal
representative,  is or  was a  director,  officer,  employee  or  agent  of  the
Corporation  or is or  was  serving  at the  request  of  the  Corporation  as a
director, officer, employee or agent of another corporation or of a partnership,
joint  venture,  trust or other  enterprise,  including  service with respect to
employee  benefit plans,  whether the basis of such proceeding is alleged action
or inaction in an official capacity as a director, officer, employee or agent or
in any other capacity while serving as a director,  officer,  employee or agent,
shall be indemnified  and held harmless by the Corporation to the fullest extent
permitted by the  Delaware  General  Corporation  Law, as the same exists or may
hereafter be amended (but, in the case of any such amendment, only to the extent
that such amendment  permits the Corporation to provide broader  indemnification
rights  than  said  law  permitted  the  Corporation  to  provide  prior to such
amendment),  against all expense, liability and loss (including attorneys' fees,
judgments, fines, ERISA excise taxes or penalties and amounts paid or to be paid
in  settlement)  reasonably  incurred or  suffered by such person in  connection
therewith and such indemnification  shall continue as to a person who has ceased
to be a director,  officer,  employee or agent and shall inure to the benefit of
his or her heirs, executors and administrators;  provided, however, that, except
as provided in this Section 2, the  Corporation  shall indemnify any such person
seeking  indemnification  in  connection  with a  proceeding  (or part  thereof)
initiated  by  such  person  only if  such  proceeding  (or  part  thereof)  was
authorized  by  the  Board  of  Directors  of  the  Corporation.  The  right  to
indemnification  conferred in this Section 2 shall be a contract right and shall
include  the  right  to be paid by the  Corporation  the  expenses  incurred  in
defending any such proceeding in advance of its final  disposition as authorized
by the Board of  Directors;  provided,  however,  that if the  Delaware  General
Corporation  Law so  requires,  the  payment  of  such  expenses  incurred  by a
director,  officer,  employee or agent of the Company in his or her  capacity as
such in advance of the final disposition of a proceeding shall be made only upon
delivery to the Corporation of an undertaking, by or on behalf of such director,
officer,  employee or agent of the Company,  to repay all amounts so advanced if
it shall ultimately be determined that such director, officer, employee or agent
of the  Company  is not  entitled  to be  indemnified  under  this  Section 2 or
otherwise.

     SECTION  3. If a claim  under  Section 2 of this  Article IX is not paid in
full by the  Corporation  within 30 days after a written claim has been received
by the  Corporation,  the claimant may at any time thereafter bring suit against
the  Corporation to recover the unpaid amount of the claim and, if successful in
whole or in part,  the claimant shall be entitled to be paid also the expense of
prosecuting  such claim. It shall be a defense to any such action (other than an
action  brought  to  enforce a claim for  expenses  incurred  in  defending  any
proceeding in advance of its final disposition  where the required  undertaking,
if any is required,  has been tendered to the Corporation) that the claimant has
not met the standard of conduct  which makes it  permissible  under the Delaware
General  Corporation  Law for the  Corporation to indemnify the claimant for the
amount  claimed, but  the burden  of proving  such  defense shall  be on  the

                                       10
<PAGE>
Corporation.  Neither the  failure of the  Corporation  (including  its Board of
Directors,  independent  legal  counsel,  or its  stockholders  to  have  made a
determination  prior to the commencement of such action that  indemnification of
the  claimant  is  proper  in the  circumstances  because  he or she has met the
applicable  standard of conduct set forth in the  Delaware  General  Corporation
Law, nor an actual  determination  by the  Corporation  (including  its Board of
Directors, independent legal counsel, or its stockholders) that the claimant has
not met such applicable standard of conduct, shall be a defense to the action or
create a presumption  that the claimant has not met the  applicable  standard of
conduct.

     SECTION  4. The  right  to  indemnification  and the  payment  of  expenses
incurred in defending a proceeding in advance of its final disposition conferred
in this  Article IX shall not be  exclusive  of any other right which any person
may have or hereafter acquire under any statute, provision of the Certificate of
Incorporation,  these By-Laws,  agreement, vote of stockholders or disinterested
directors or otherwise.

     SECTION 5. The  Corporation  may maintain  insurance,  at its  expense,  to
protect itself and any director,  officer,  employee or agent of the Corporation
or another corporation,  partnership,  joint venture,  trust or other enterprise
against any such  expense,  liability  or loss,  whether or not the  corporation
would have the power to indemnify such person against such expense, liability or
loss under the Delaware General Corporation Law.


                                    ARTICLE X
                                  MISCELLANEOUS

     SECTION 1. STOCK OPTIONS.  The  Corporation may not grant any stock options
having an exercise  price that is less than 100% of the fair market value of the
underlying  stock on the date of grant.  Furthermore,  the  Corporation  may not
reduce the exercise  price of any stock option  granted under any existing stock
option  plan or under  any stock  option  plan  adopted  after the date of these
amended By-Laws.

     SECTION 2.  CONVERTIBLE  SECURITIES.  The Corporation may not sell or issue
any security of the Corporation  convertible,  exercisable or exchangeable  into
shares of common  stock of the  Corporation,  having a  conversion,  exercise or
exchange  price per share which is subject to downward  adjustment  based on the
market price of the common stock at the time of conversion, exercise or exchange
of such security into common stock (except for appropriate  adjustments  made to
give effect to any stock splits or stock dividends).

     SECTION  3. SALE OF STOCK.  The  Corporation  may not enter  into:  (a) any
equity line or similar  agreement or  arrangement;  or (b) any agreement to sell
common stock of the  Corporation  (or any security  convertible,  exercisable or
exchangeable  into shares of common stock ("Common Stock  Equivalent")) at a per
share price (or,  with respect to a Common Stock  Equivalent,  at a  conversion,
exercise or exchange  price,  as the case may be  ("Equivalent  Price")) that is
fixed after the  execution  date of the  agreement,  whether or not based on any
predetermined  price-setting formula or calculation method.  Notwithstanding the


                                       11
<PAGE>
foregoing, however, a price protection clause shall be permitted in an agreement
for sale of Common Stock or Common Stock Equivalent, if such clause provides for
an  adjustment  to the price per share of Common  Stock or,  with  respect  to a
Common Stock  Equivalent,  to the Equivalent  Price (provided that such price or
Equivalent Price is fixed on or before the execution date of the  agreement)(the
"Fixed Price") in the event that the Corporation, during the period beginning on
the date of the  agreement  and ending no later  than 90 days after the  closing
date of the transaction, sells shares of Common Stock or Common Stock Equivalent
to another  investor at a price or Equivalent  Price,  as the case may be, below
the Fixed Price.
