EXHIBIT 3.6

                      RESTATED CERTIFICATE OF INCORPORATION
                                       OF
                            HOMESTAKE MINING COMPANY

                  In accordance  with the  provisions of Sections 242 and 245 of
the General  Corporation Law of the State of Delaware,  HOMESTAKE MINING COMPANY
does  hereby  amend and  restate  its  Restated  Certificate  of  Incorporation.
HOMESTAKE  MINING  COMPANY  was  incorporated  under the name  HOMESTAKE  MINING
CORPORATION,  and the original  Certificate of Incorporation  was filed with the
Secretary  of  State  on  November  28,  1983.  This  Restated   Certificate  of
Incorporation was duly adopted by the Stockholders and the Board of Directors of
the Company in  accordance  with  Sections 242 and 245 of the  Delaware  General
Corporation Law, as amended.

                  The  text of the  Restated  Certificate  of  Incorporation  is
hereby amended and restated so as to read in its entirety as follows:

                  ONE: The name of this corporation is

                            HOMESTAKE MINING COMPANY.

                  TWO:  The address of the  registered  office of the Company in
the State of Delaware is 1209 Orange Street,  in the City of Wilmington,  County
of New  Castle,  and the name of its  registered  agent at that  address  is The
Corporation Trust Company.

                  THREE: The purpose of the Company is to engage in any lawful
act or activity for which  corporations may be organized under the General 
Corporation Law of Delaware.

                  FOUR: The total number of shares of all classes of stock which
the Company is authorized to issue is 460,000,001 shares. Of these,  450,000,000
shares  shall be  shares of  common  stock and the par value of each such  share
shall be $1.00 ("Common Stock"),  10,000,000 shares shall be shares of preferred
stock and the par value of each such share shall be $1.00  ("Preferred  Stock"),
and one share  shall be a share of  special  voting  stock with  certain  voting
rights and the par value of such share shall be $1.00 ("Special  Voting Stock").
The aggregate par value of all shares is $460,000,001.

                  The number of shares of  Preferred  Stock  authorized  by this
Article FOUR may be  increased or decreased  (but not below the number of shares
then  outstanding) by the  affirmative  vote of the holders of a majority of the
total  voting  power of all  outstanding  shares of the Common Stock and Special
Voting  Stock of the  Company  and,  subject  to any  limitation  imposed in any
resolution  adopted  by the Board of  Directors  providing  for the issue of any
particular  series of Preferred  Stock, the holders of Preferred Stock shall not
be entitled to vote upon any such increase or decrease.





                  The record  holder of the  Special  Voting  Stock shall not be
entitled  to  receive  any  dividends  or other  distributions  or to receive or
participate  in any  distribution  of assets upon any  voluntary or  involuntary
liquidation,  dissolution  or winding  up of the  Company.  Except as  otherwise
required by applicable law, at each annual or special meeting of stockholders of
the Company the record  holder of the Special  Voting Stock shall be entitled to
vote on all  matters  submitted  to a vote of the  holders of the Common  Stock,
voting  together  with the holders of the Common Stock as a single class (except
as otherwise provided herein or by applicable law), and the record holder of the
Special  Voting  Stock  shall be entitled to cast on any such matter a number of
votes  equal to the number of  Exchangeable  Shares  ("Exchangeable  Shares") of
Homestake Canada Inc. and its successors at law, whether by merger, amalgamation
or  otherwise,  outstanding  as of the  record  date for such  annual or special
meeting of stockholders, which are not owned by the Company or any subsidiary of
the Company.  At such time as no  Exchangeable  Shares (other than  Exchangeable
Shares  owned  by  the  Company  or any  subsidiary  of the  Company)  shall  be
outstanding and there are no shares of stock,  debt, options or other agreements
which could give rise to the issuance of any  Exchangeable  Shares to any person
(other than the Company or any subsidiary of the Company),  the share of Special
Voting  Stock  shall  automatically  be  redeemed  for $1.00,  and upon any such
redemption or other  purchase or  acquisition of the Special Voting Stock by the
Company the share of Special  Voting Stock shall be deemed  retired and canceled
and may not be reissued.

                  FIVE: The Board of Directors shall have the authority, subject
to  limitations  prescribed  by law and the  provisions of this Article FIVE, to
determine and provide for the issuance of Preferred  Stock in one or more series
and to  establish  or alter the  number of  shares to be  included  in each such
series,  and to fix the voting powers,  designations,  preferences and relative,
participating,  optional  or  other  rights,  if any,  and  the  qualifications,
limitations  or  restrictions  of the  shares of each such  series of  Preferred
Stock.

                  The Board of Directors  shall have the  authority,  subject to
the limitations  stated in any resolution or resolutions  originally  fixing the
number of shares constituting any series, to increase or decrease (but not below
the number of shares of such  series then  outstanding)  the number of shares of
any such series subsequent to the issuance of shares of that series. In case the
number of shares of any series shall be so  decreased,  the shares  constituting
such  decrease  shall resume the status of  authorized  but  unissued  shares of
Preferred Stock.

                  The  authority of the Board of Directors  with respect to each
series shall  include,  but not be limited to, the  authority to  determine,  by
resolution or resolutions  providing for the issue of shares of each series, the
following:  (1) the  number  of shares in and  distinctive  designation  of each
series;  (2) the  dividend  rate on each series and whether  dividends  shall be
cumulative;  (3) the voting  rights,  if any,  of the  shares of each  series in
addition to those  required by law,  including the number of votes per share and
any  rights  of the  shares  of  each  series  to vote as a  separate  class  in
connection with any specified transaction or item of business;  (4) whether each
series shall have conversion  privileges and, if so, the terms and conditions of
such conversion;  (5) whether the shares of each series shall be redeemable and,
if so,  the terms and  conditions  of such  redemption;  (6) the  rights of each
series in the event of  voluntary or  involuntary  liquidation,  dissolution  or
winding up of the Company; (7) whether each series shall


                                       2



be subject to the  operation of a purchase,  retirement  or sinking fund and, if
so,  the  terms  and  conditions  thereof;  and (8) any  other  preferences  and
relative,  participating,  optional or other special rights, and qualifications,
limitations or restrictions of each series.

                                    -------

 Series A Participating Cumulative Preferred Stock

                  Section 1.  Designation  and  Number of Shares.  The shares of
such series shall be designated as "Series A Participating  Cumulative Preferred
Stock"  (the  "Series A  Preferred  Stock").  The par value of each share of the
Series A Preferred Stock shall be $1.00.  The number of shares  constituting the
Series A Preferred Stock shall be 4,500,000; provided however, that if more than
a total of 4,500,000  shares of Series A Preferred  Stock shall be issuable upon
the  exercise  of Rights  issued  pursuant to the Rights  Agreement  dated as of
October 16, 1987, as amended,  (the "Rights Agreement"),  the Board of Directors
of the Company, pursuant to Section 151(g) of the General Corporation Law of the
State of Delaware,  shall direct by resolution or resolutions that a certificate
be properly executed,  acknowledged,  filed and recorded, in accordance with the
provisions  of Section 103 thereof,  providing for the total number of shares of
Series A Preferred  Stock  authorized  to be issued be increased  (to the extent
that this Restated  Certificate  of  Incorporation  then permits) to the largest
number of whole shares  (rounded up to the nearest whole  number)  issuable upon
exercise of such Rights.

                  Section 2.  Dividends or Distributions.

                  (a) Subject to the prior and superior rights of the holders of
shares of any other  series of Preferred  Stock or other class of capital  stock
not by its terms  ranking on a parity with, or junior to, the shares of Series A
Preferred Stock with respect to dividends, the holders of shares of the Series A
Preferred Stock shall be entitled to receive,  when and as declared by the Board
of Directors,  out of the assets of the Company legally available therefor,  (1)
quarterly  dividends payable in cash on the first day of March, June,  September
and  December  in each  year  (each  such  date  being  referred  to herein as a
"Quarterly  Dividend Payment Date"),  commencing on the first Quarterly Dividend
Payment  Date after the first  issuance  of a share or a fraction  of a share of
Series A Preferred  Stock,  of $10 per whole share (rounded to the nearest cent)
less the amount of all cash dividends  declared on the Series A Preferred  Stock
pursuant to the following clause (2) since the immediately  preceding  Quarterly
Dividend  Payment Date or, with respect to the first Quarterly  Dividend Payment
Date,  since the first  issuance of any share or fraction of a share of Series A
Preferred Stock, and (2) dividends  payable in cash on the payment date for each
cash dividend declared on the Common Stock in an amount per whole share (rounded
to the nearest  cent) equal to the Formula  Number then in effect times the cash
dividends  then to be paid on each share of Common  Stock.  In addition,  if the
Company  shall pay any  dividend or make any  distribution  on the Common  Stock
payable in assets,  securities  or other forms of noncash  consideration  (other
than dividends or distributions solely in shares of Common Stock), then, in each
such case,  the Company  shall  simultaneously  pay or make on each  outstanding
share of Series A Preferred Stock a dividend or distribution in like kind of the
Formula Number then in

                                       3



effect times such dividend or distribution on each share of the Common Stock. As
used herein,  the "Formula Number" shall be 100; provided,  however,  that if at
any time  after  November  2, 1987,  the  Company  shall (i)  declare or pay any
dividend  on the  Common  Stock  payable  in shares of Common  Stock or make any
distribution on the Common Stock in shares of Common Stock, (ii) subdivide (by a
stock split or otherwise) the  outstanding  shares of Common Stock into a larger
number of shares of Common Stock or (iii)  combine (by a reverse  stock split or
otherwise)  the  outstanding  shares of Common  Stock  into a smaller  number of
shares of Common  Stock,  then in each such event the  Formula  Number  shall be
adjusted to a number  determined  by  multiplying  the Formula  Number in effect
immediately  prior to such event by a fraction,  the  numerator  of which is the
number of shares of Common  Stock that are  outstanding  immediately  after such
event and the  denominator of which is the number of shares that are outstanding
immediately  prior to such event (and  rounding the result to the nearest  whole
number);  and provided further,  that if at any time after November 2, 1987, the
Company  shall issue any shares of its capital  stock in a  reclassification  or
change  of  the  outstanding   shares  of  Common  Stock   (including  any  such
reclassification  or change in connection  with a merger in which the Company is
the surviving corporation),  then in each such event the Formula Number shall be
appropriately adjusted to reflect such reclassification or change.

                  (b) The Company  shall declare a dividend or  distribution  on
the Series A Preferred Stock as provided in Section 2(a) immediately prior to or
at the same time it  declares a dividend  or  distribution  on the Common  Stock
(other  than a  dividend  or  distribution  solely in  shares of Common  Stock);
provided,  however, that, in the event no dividend or distribution (other than a
dividend or  distribution in shares of Common Stock) shall have been declared on
the Common Stock during the period between any Quarterly  Dividend  Payment Date
and the next subsequent  Quarterly  Dividend Payment Date, a dividend of $10 per
share on the Series A  Preferred  Stock  shall  nevertheless  be payable on such
subsequent  Quarterly  Dividend  Payment Date.  The Board of Directors may fix a
record  date for the  determination  of holders of shares of Series A  Preferred
Stock entitled to receive a dividend or  distribution  declared  thereon,  which
record date shall be the same as the record date for any corresponding  dividend
or distribution on the Common Stock.

                  (c)  Dividends  shall  begin to accrue  and be  cumulative  on
outstanding  shares of Series A  Preferred  Stock  from and after the  Quarterly
Dividend  Payment Date next  preceding the date of original issue of such shares
of Series A Preferred Stock;  provided,  however,  that dividends on such shares
which are  originally  issued  after the record  date for the  determination  of
holders of shares of Series A  Preferred  Stock  entitled to receive a quarterly
dividend and on or prior to the next succeeding  Quarterly Dividend Payment Date
shall begin to accrue and be cumulative  from and after such Quarterly  Dividend
Payment Date.  Notwithstanding  the  foregoing,  dividends on shares of Series A
Preferred  Stock which are  originally  issued  prior to the record date for the
first Quarterly Dividend Payment,  shall be calculated as if cumulative from and
after the March 1, June 1,  September  1 or December 1, as the case may be, next
preceding  the date of  original  issuance  of such  shares.  Accrued but unpaid
dividends  shall not bear  interest.  Dividends  paid on the  shares of Series A
Preferred Stock in an amount less than the total amount of such dividends at the
time  accrued  and  payable  on such  shares  shall be  allocated  pro rata on a
share-by-share basis among all such shares at the time outstanding.


                                       4



                  (d) So long as any shares of the Series A Preferred  Stock are
outstanding,  no dividends  or other  distributions  shall be declared,  paid or
distributed,  or set aside for  payment or  distribution,  on the  Common  Stock
unless,  in each case, the dividend required by this Section 2 to be declared on
the Series A Preferred Stock shall have been declared.

                  (e) The  holders  of the  shares of Series A  Preferred  Stock
shall not be entitled to receive any dividends or other distributions  except as
provided herein.

                  Section 3.  Voting  Rights.  The  holders of shares of Series
A  Preferred  Stock  shall  have the  following  voting rights:

                  (a) Each holder of Series A Preferred  Stock shall be entitled
to a number of votes equal to the Formula Number then in effect,  for each share
of Series A Preferred  Stock held of record on each  matter on which  holders of
the Common Stock are entitled to vote, multiplied by the maximum number of votes
which the holders of the Common Stock then have with respect to such matter.

                  (b) Except as otherwise  provided herein or by applicable law,
the holders of shares of Series A  Preferred  Stock and the holders of shares of
Common  Stock shall vote  together as one class for the election of directors of
the Company and on all other matters  submitted to a vote of stockholders of the
Company.

                  (c) If at the time of any annual meeting of  stockholders  for
the election of directors, the equivalent of six quarterly dividends (whether or
not consecutive)  payable on any share or shares of Series A Preferred Stock are
in default,  the number of directors  constituting the Board of Directors of the
Company  shall be  increased  by two. In addition  to voting  together  with the
holders of Common Stock for the election of other directors of the Company,  the
holders of record of the Series A Preferred Stock,  voting separately as a class
to the  exclusion  of the  holders of Common  Stock,  shall be  entitled at said
meeting of stockholders (and at each subsequent annual meeting of stockholders),
unless all  dividends  in arrears  have been paid or declared  and set apart for
payment prior thereto, to vote for the election of two directors of the Company,
the holders of any Series A Preferred  Stock being  entitled to cast a number of
votes per share of Series A Preferred Stock equal to the Formula  Number.  Until
the default in payments of all  dividends  which  permitted the election of said
directors  shall  cease to exist any  director  who shall  have been so  elected
pursuant to the next preceding  sentence may be removed at any time, either with
or without cause,  only by the affirmative  vote of the holders of the shares at
the time  entitled to cast a majority  of the votes  entitled to be cast for the
election of any such  director at a special  meeting of such holders  called for
that purpose,  and any vacancy thereby created may be filled by the vote of such
holders.  If and when such  default  shall  cease to exist,  the  holders of the
Series A  Preferred  Stock shall be divested  of the  foregoing  special  voting
rights,  subject to  revesting  in the event of each and every  subsequent  like
default in payments of dividends.  Upon the termination of the foregoing special
voting  rights,  the terms of office of all  persons  who may have been  elected
directors pursuant to said special voting rights shall forthwith terminate,  and
the number of directors  constituting the Board of Directors shall be reduced by
two. The voting

                                       5



rights  granted by this  Section  3(c) shall be in addition to any other  voting
rights granted to the holders of the Series A Preferred Stock in this Section 3.

                  (d) Except as provided herein,  in Section 11 or by applicable
law, holders of Series A Preferred Stock shall have no special voting rights and
their consent  shall not be required  (except to the extent they are entitled to
vote with holders of Common Stock as set forth herein) for authorizing or taking
any corporate action.

                  Section 4.  Certain Restrictions.

                  (a)  Whenever  quarterly   dividends  or  other  dividends  or
distributions  payable on the Series A Preferred  Stock as provided in Section 2
are in  arrears,  thereafter  and until all  accrued  and unpaid  dividends  and
distributions,  whether or not declared,  on shares of Series A Preferred  Stock
outstanding shall have been paid in full, the Company shall not

                  (i) declare or pay dividends on, make any other  distributions
         on, or redeem or purchase or otherwise  acquire for  consideration  any
         shares  of  stock  ranking  junior  (either  as to  dividends  or  upon
         liquidation,  dissolution  or  winding  up) to the  Series A  Preferred
         Stock;

                  (ii)   declare  or  pay   dividends   on  or  make  any  other
         distributions  on any shares of stock ranking on a parity (either as to
         dividends  or upon  liquidation,  dissolution  or winding  up) with the
         Series A Preferred Stock, except dividends paid ratably on the Series A
         Preferred  Stock  and all such  parity  stock on  which  dividends  are
         payable or in arrears in  proportion  to the total amounts to which the
         holders of all such shares are then entitled;

                  (iii)   redeem  or   purchase   or   otherwise   acquire   for
         consideration  shares of any stock  ranking  on a parity  (either as to
         dividends  or upon  liquidation,  dissolution  or winding  up) with the
         Series A  Preferred  Stock,  provided  that the Company may at any time
         redeem,  purchase or otherwise  acquire shares of any such parity stock
         in  exchange  for  shares of any stock of the  Company  ranking  junior
         (either as to dividends or upon dissolution, liquidation or winding up)
         to the Series A Preferred Stock: or

                  (iv)  purchase  or  otherwise  acquire for  consideration  any
         shares of Series A Preferred Stock, or any shares of stock ranking on a
         parity with the Series A Preferred  Stock,  except in accordance with a
         purchase offer made in writing or by publication  (as determined by the
         Board of  Directors)  to all  holders of such shares upon such terms as
         the Board of Directors,  after  consideration of the respective  annual
         dividend  rates  and  other  relative  rights  and  preferences  of the
         respective  series  and  classes,  shall  determine  in good faith will
         result in fair and equitable  treatment among the respective  series or
         classes.

                  (b) The Company shall not permit any subsidiary of the Company
to purchase or otherwise  acquire for  consideration  any shares of stock of the
Company unless the Company


                                       6



could, under paragraph (a) of this Section 4, purchase or otherwise acquire such
shares at such time and in such manner.

                  Section  5.   Liquidation   Rights.   Upon  the   liquidation,
dissolution or winding up of the Company,  whether voluntary or involuntary,  no
distribution  shall be made (1) to the holders of shares of stock ranking junior
(either as to dividends or upon liquidation,  dissolution, or winding up) to the
Series A Preferred Stock unless,  prior thereto, the holders of shares of Series
A Preferred  Stock shall have received an amount equal to the accrued and unpaid
dividends and  distributions  thereon,  whether or not declared,  to the date of
such payment, plus an amount equal to the greater of (x) $75 per share or (y) an
aggregate  amount per share equal to the Formula Number then in effect times the
aggregate  amount to be distributed per share to holders of Common Stock, or (2)
to the  holders of stock  ranking on a parity  (either as to  dividends  or upon
liquidation,  dissolution  or  winding  up) with the Series A  Preferred  Stock,
except  distributions made ratably on the Series A Preferred Stock and all other
such parity stock in proportion to the total amounts to which the holders of all
such shares are entitled upon such liquidation, dissolution or winding up.

                  Section 6.  Consolidation,  Merger,  etc.  In case the Company
shall enter into any consolidation,  merger, combination or other transaction in
which the shares of Common Stock are  exchanged  for or changed into other stock
or  securities,  cash or any  other  property,  then in any  such  case the then
outstanding  shares  of  Series A  Preferred  Stock  shall  at the same  time be
similarly  exchanged  or  changed in an amount  per share  equal to the  Formula
Number then in effect times the aggregate amount of stock,  securities,  cash or
any other  property  (payable  in kind),  as the case may be,  into which or for
which each share of Common Stock is exchanged or changed.

                  Section 7.  No Redemption; No Sinking Fund.

                  (a) The  shares  of  Series A  Preferred  Stock  shall  not be
subject to  redemption by the Company or at the option of any holder of Series A
Preferred Stock;  provided,  however, that the Company may purchase or otherwise
acquire  outstanding shares of Series A Preferred Stock in the open market or by
offer to any holder or holders of shares of Series A Preferred Stock.

                  (b) The shares of Series A  Preferred  Stock shall not be 
subject to or entitled to the  operation of a retirement or sinking fund.

                  Section 8.  Ranking.  The Series A Preferred  Stock shall rank
junior to all other series of Preferred  Stock of the Company,  unless the Board
of  Directors  shall  specifically  determine  otherwise  in fixing the  powers,
preferences  and relative,  participating,  optional and other special rights of
the shares of such series and the  qualifications,  limitations and restrictions
thereof.

                  Section 9.  Fractional  Shares.  The Series A  Preferred 
Stock  shall be issuable  upon  exercise  of the Rights  issued  pursuant to the
Rights  Agreement  in whole  shares or in any  fraction  of a share  that is not
smaller than one one-hundredth (l/l00th) of a share or any integral


                                       7



multiple of such fraction.  In lieu of fractional shares, the Company,  prior to
the first  issuance  of a share or a fraction  of a share of Series A  Preferred
Stock, may elect (1) to issue certificates  evidencing such authorized  fraction
of a share of  Series A  Preferred  Stock  or (2) to issue  depository  receipts
evidencing  such  authorized  fraction  of a share of Series A  Preferred  Stock
pursuant to an  appropriate  agreement  between  the  Company  and a  depository
selected by the Company,  provided  that such  agreement  shall provide that the
holders of such  depository  receipts shall have all the rights,  privileges and
preferences  to which they are  entitled  as  beneficial  owners of the Series A
Preferred Stock.

                  Section  10.  Reacquired   Shares.  Any  shares  of  Series  A
Preferred  Stock  purchased or  otherwise  acquired by the Company in any manner
whatsoever shall be retired and canceled promptly after the acquisition thereof.
All such shares shall upon their  cancellation  become  authorized  but unissued
shares of Preferred  Stock,  without  designation as to series until such shares
are  once  more  designated  as part of a  particular  series  by the  Board  of
Directors pursuant to the provisions of Article FIVE hereof.

                  Section 11.  Amendment.  None of the powers,  preferences  and
relative,  participating,  optional  and other  special  rights of the  Series A
Preferred  Stock as provided  herein  shall be amended in any manner which would
alter or change the powers, preferences,  rights or privileges of the holders of
Series A Preferred Stock so as to affect them adversely  without the affirmative
vote of the  holders  of at least 66 2/3% of the  outstanding  shares of Series
A Preferred Stock, voting as a separate class.

                                   ----------

                  SIX:  No holder of shares of stock of any class of the Company
shall be  entitled  as of right to  purchase  or  subscribe  for any part of any
unissued  stock of the Company or of any new or additional  authorized  stock of
the  Company  of any  class  whatsoever,  or of any issue of  securities  of the
Company  convertible into stock,  whether such stock or securities be issued for
money or for a  consideration  other than money or by way of  dividend,  but any
such  unissued  stock  or  such  new or  additional  authorized  stock  or  such
securities convertible into stock may be issued and disposed of to such persons,
firms,  corporations  and  associations,  and upon  such  terms as may be deemed
advisable by the Board of Directors  without  offering to  stockholders  then of
record or any class of stockholders any thereof upon any terms.

                  SEVEN:  In  furtherance  and not in  limitation  of the powers
conferred by statute,  the Board of Directors is expressly  authorized  to make,
repeal, alter, amend and rescind any or all of the bylaws of the Company.

                  EIGHT:  The number of directors of the Company  shall be fixed
from time to time by a bylaw or  amendment  thereof duly adopted by the Board of
Directors or by the stockholders, or except as may be set forth in a certificate
filed  under  Section  151(g)  of the  General  Corporation  Law of the State of
Delaware pursuant to Article FIVE hereof.


                                       8



                  NINE:  The Board of  Directors  shall be and is  divided  into
three  classes,  Class I, Class II and Class III,  as nearly  equal in number of
directors  as  possible,  with the term of office of the  directors of one class
expiring each year. Each director shall be elected to serve for a term ending on
the date of the third  annual  meeting  of  stockholders  following  the  annual
meeting of stockholders at which such director was elected.

                  In  the  event  of any  change  in the  authorized  number  of
directors,   the  Board  of  Directors   shall   apportion   any  newly  created
directorships  to, or reduce  the  number of  directorships  in,  such  class or
classes as shall,  so far as possible,  equalize the number of directors in each
class. If,  consistently with the rule that the three classes shall be as nearly
equal in number of directors as possible, any newly created directorships may be
allocated to more than one class,  the Board of Directors shall allocate them to
the  classes  the terms of office of which are due to expire at the latest  date
following such allocation.

                  Notwithstanding  any of the  foregoing,  each  director  shall
serve for a term  continuing  until the annual meeting of  stockholders at which
the term of the class to which he was elected expires and until his successor is
elected and qualified or until his earlier death, resignation or removal.

                  Any  vacancies  in the  Board  of  Directors  for any  reason,
including any newly  created  directorships  resulting  from any increase in the
number  of  directors,  may be filled  by the  Board of  Directors,  acting by a
majority of the directors then in office,  although less than a quorum;  and any
directors so chosen  shall hold office until the next  election of the class for
which such directors shall have been chosen, and until their successors shall be
elected and qualified.

                  The  provisions  of this  Article NINE shall be subject to the
provisions  of  a  certificate   filed  under  Section  151(g)  of  the  General
Corporation Law of the State of Delaware pursuant to Article FIVE hereof.

                  TEN:  Except as may be set forth in a certificate  filed under
Section 151(g) of the General  Corporation Law of the State of Delaware pursuant
to Article  FIVE  hereof,  a director may be removed from office only for cause,
and only by the  affirmative  vote of the  holders  of a  majority  of the total
voting power of all outstanding  shares of stock of the Company entitled to vote
at an election of  directors  and who would be entitled to vote for the election
of a director to fill the vacancy created by such removal.

                  ELEVEN: Elections of directors shall be by written ballot 
unless the bylaws of the Company shall otherwise provide.

                  TWELVE: No action shall be taken by the stockholders except at
an annual or special meeting of stockholders.

                  THIRTEEN:  Special  meetings of the stockholders of the
Company for any purpose or purposes  may be called at any time only by the Board
of Directors, the Chairman of the Board


                                       9

been duly  designated by the Board of Directors and whose powers and  authority,
as provided in a  resolution  of the Board of  Directors or in the bylaws of the
Company,  include the power to call such meeting,  or by stockholders having not
less  than  seventy-five  percent  (75%)  of  the  total  voting  power  of  all
outstanding shares of stock of the Company, and such special meetings may not be
called by any other  person or persons;  provided,  however,  that if and to the
extent  that any  special  meeting  of  stockholders  may be called by any other
person or persons  specified in any  provisions of the Restated  Certificate  of
Incorporation or any amendment  thereto,  or any certificate filed under Section
151(g) of the  General  Corporation  Law of the State of  Delaware  pursuant  to
Article FIVE hereof, then such special meeting may also be called by such person
or persons in the manner, at the times and for the purposes so specified.

                  FOURTEEN:  Except as may be set forth in a  certificate  filed
