                                       OF
                              McKESSON CORPORATION
                    (Originally Incorporated on July 7, 1994
                      Under the Name of SP Ventures, Inc.)



                                   ARTICLE I.

The name of the Corporation is McKesson Corporation.


                                  ARTICLE II.

The address of the registered office of the Corporation within the State of
Delaware is 32 Loockerman Square, Suite L-100, City of Dover 19901, County of
Kent. The name of the registered agent of the Corporation at such address is The

                                  ARTICLE III.

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


                                  ARTICLE IV.

The total number of shares of stock of all classes which the Corporation has
authority to issue is 300,000,000 shares, divided into 100,000,000 shares of
Series Preferred Stock, par value $0.01 per share (herein called the "Series
Preferred Stock"), and 200,000,000 shares of Common Stock, par value $.01 per
share (herein called the "Common Stock"). The aggregate par value of all shares
having par value is $3,000,000.

The Board of Directors of the Corporation is expressly authorized, as shall be
stated and expressed in the resolution or resolutions it adopts, subject to
limitations prescribed by law and the provisions of this Article IV, to provide
for the issuance of the shares of Series Preferred Stock in one or more class or
series, in addition to the shares thereof specifically provided for in this
Article IV, and by filing a certificate pursuant to the applicable law of the
State of Delaware, to establish from time to time the number of shares to be
included in each such series, and to fix for each such class or series such
voting powers, full or limited, or no voting powers, and such distinctive
designations, powers, preferences and relative, participating, optional or other
special rights and such qualifications, limitations or restrictions thereof,
including without limitation, the authority to provide that any such class or
series may be (i) subject to redemption at such time or times and at such price
or prices; (ii) entitled to receive dividends (which may be cumulative or non-
cumulative) at such rates, on such conditions, and at such times, and payable in
preference to, or in relation to, the dividends payable on any other class or
classes or any other series; (iii) entitled to such rights upon the dissolution
of, or upon any distribution of the assets of, the Corporation; (iv) convertible


                                       1

 
into, or exchangeable for, shares of any other class or classes of stock, or of
any other series of the same or any other class or classes of stock, of the
Corporation at such price or prices or at such rates of exchange and with such
adjustments; or (v) subject to the terms and amounts of any sinking fund
provided for the purchase or redemption of the shares of such series; all as may
be stated in such resolution or resolutions.

The number of authorized shares of Series Preferred Stock may be increased or
decreased (but not below the number of shares thereof then outstanding) by the
affirmative vote of the holders of a majority of the Common Stock, without a
vote of the holders of the Series Preferred Stock, as the case may be, or of any
series thereof, unless a vote of any such holders is required pursuant to the
provisions of this Article IV or the certificate or certificates establishing
any additional series of such stock.

A description of each class of the Corporation's stock, with the powers,
designations, preferences and relative, participating, optional and other
rights, if any, and the qualifications, limitations and restrictions thereof, is
as follows:


I.  SERIES PREFERRED STOCK

A.  General Provisions Relating to All Series

1. The Board of Directors shall have authority to classify and reclassify any
unissued shares of the Series Preferred Stock from time to time by setting or
changing in any one or more respects the powers, designations, preferences and
relative, participating, optional and other rights, if any, and the
qualifications, limitations and restrictions of the Series Preferred Stock.
Subject to the foregoing, the power of the Board of Directors to classify and
reclassify any of the shares of Series Preferred Stock shall include, without
limitation, subject to the provisions of this Certificate of Incorporation,
authority to classify or reclassify any unissued shares of such stock into one
or more series of Series Preferred Stock, and to divide and classify shares of
any series into one or more series of Series Preferred Stock by determining,
fixing or altering one or more of the following:

  (a) The distinctive designation of such series and the number of shares to
  constitute such series; provided that, unless otherwise prohibited by the
  terms of such or any other series, the number of shares of any series may be
  decreased by the Board of Directors in connection with any classification or
  reclassification of unissued shares and the number of shares of such series
  may be increased by the Board of Directors in connection with any such
  classification or reclassification, and any shares of any series which have
  been redeemed, purchased, otherwise acquired or converted into shares of
  Common Stock or any other series shall remain part of the authorized Series
  Preferred Stock and be subject to classification and reclassification as
  provided in this Section.

  (b) Whether or not and, if so, the rates, amounts and times at which, and the
  conditions under which, dividends shall be payable on shares of such series,
  whether any such dividends shall rank senior or junior to or on a parity with
  the dividends payable on any other series of Series Preferred Stock, and the
  status of any such dividends as cumulative, cumulative to a limited extent or
  non-cumulative and as participating or non-participating.

  (c) Whether or not shares of such series shall have voting rights, in addition
  to any voting rights provided by law and, if so, the terms of such voting
  rights.

                                       2

 
  (d) Whether or not shares of such series shall have conversion or exchange
  privileges and, if so, the terms and conditions thereof, including provision
  for adjustment of the conversion or exchange rate in such events or at such
  times as the Board of Directors shall determine.

  (e) Whether or not shares of such series shall be subject to redemption and,
  if so, the terms and conditions of such redemption, including the date or
  dates upon or after which they shall be redeemable and the amount per share
  payable in case of redemption, which amount may vary under different
  conditions and at different redemption dates; and whether or not there shall
  be any sinking fund or purchase account in respect thereof, and if so, the
  terms thereof.

  (f) The rights of the holders of shares of such series upon the liquidation,
  dissolution or winding up of the affairs of, or upon any distribution of the
  assets of, the Corporation, which rights may vary depending upon whether such
  liquidation, dissolution or winding up is voluntary or involuntary and, if
  voluntary, may vary at different dates, and whether such rights shall rank
  senior or junior to or on a parity with such rights of any other series of
  Series Preferred Stock.

  (g) Whether or not there shall be any limitations applicable, while shares of
  such series are outstanding, upon the payment of dividends or making of
  distributions on, or the acquisition of, or the use of moneys for purchase or
  redemption of, any stock of the Corporation, or upon any other action of the
  Corporation, including action under this Section, and, if so, the terms and
  conditions thereof .

  (h) Any other powers, designations, preferences and relative, participating,
  optional and other rights, if any, and any other qualifications, limitations
  and restrictions, on the shares of such series, not inconsistent with law and
  this Certificate of Incorporation.

2. For the purposes hereof and of any certificate providing for the
classification or reclassification of any shares of Series Preferred Stock or of
any other charter document of the Corporation (unless otherwise provided in any
such certificate or document), any class or series of stock of the Corporation
shall be deemed to rank:

  (a) Prior to a particular class or series of stock if the holders of such
  class or classes or series shall be entitled to the receipt of dividends or of
  amounts distributable in the event of any liquidation, dissolution or winding
  up, as the case may be, in preference to or with priority over the holders of
  such particular class or series of stock;

  (b) On a parity with a particular class or series of stock, whether or not the
  dividend rates, dividend payment dates, voting rights or redemption or
  liquidation prices per share thereof, be different from those of such
  particular class or series of stock, if the rights of holders of such class or
  classes or series to the receipt of dividends or of amounts distributable in
  event of any liquidation, dissolution or winding up, as the case may be, shall
  be neither (i) in preference to, or with priority over, nor (ii) subject or
  subordinate to, the rights of holders of such particular class or series of
  stock in respect of the receipt of dividends or of amounts distributable in
  the event of any liquidation, dissolution or winding up of the Corporation, as
  the case may be; and

  (c) Junior to a particular class or series of stock if the rights of the
  holders of such class or classes or series shall be subject or subordinate to
  the rights of the holders of such particular class or series of stock in
  respect of the receipt of dividends or of amounts distributable in the event
  of any liquidation, dissolution or winding up, as the case may be.

                                       3

 
B.  Series A Junior Participating Preferred Stock

1.  Designation and Amount. The shares of this series shall be designated as
"Series A Junior Participating Preferred Stock" and the number of shares
constituting such series shall initially be 10,000,000, par value $0.01 per
share, such number of shares to be subject to increase or decrease by action of
the Board of Directors as evidenced by a certificate or certificates evidencing
such change.

2. Dividends and Distributions.

  (a) The holders of shares of Series A Junior Participating Preferred Stock
  shall be entitled to receive, when, as and if declared by the Board of
  Directors out of funds legally available for the purpose, quarterly dividends
  payable in cash on the first business day of January, April, July and October
  in each year (each such date being referred to herein as a "Series A Quarterly
  Dividend Payment Date"), commencing on the first Series A Quarterly Dividend
  Payment Date after the first issuance of a share or fraction of a share of
  Series A Junior Participating Preferred Stock, in an amount per share (rounded
  to the nearest cent) equal to the greater of (i) $10.00 or (ii) subject to the
  provision for adjustment hereinafter set forth, 100 times the aggregate per
  share amount of all cash dividends, and 100 times the aggregate per share
  amount (payable in kind) of all non-cash dividends or other distributions
  other than a dividend payable in shares of Common Stock or a subdivision of
  the outstanding shares of Common Stock (by reclassification or otherwise),
  declared on the Common Stock since the immediately preceding Series A
  Quarterly Dividend Payment Date, or, with respect to the first Series A
  Quarterly Dividend Payment Date, since the first issuance of any share or
  fraction of a share of Series A Junior Participating Preferred Stock. In the
  event the Corporation shall at any time after November 1, 1994 (the "Rights
  Declaration Date") (A) declare any dividend on Common Stock payable in shares
  of Common Stock, (B) subdivide the outstanding Common Stock, or (C) combine
  the outstanding Common Stock into a smaller number of shares, then in each
  such case the amount to which holders of shares of Series A Junior
  Participating Preferred Stock were entitled immediately prior to such event
  under clause (ii) of the preceding sentence shall be adjusted by multiplying
  such amount by a fraction the numerator of which is the number of shares of
  Common Stock outstanding immediately after such event and the denominator of
  which is the number of shares of Common Stock that were outstanding
  immediately prior to such event.

  (b) The Corporation shall declare a dividend or distribution on the Series A
  Junior Participating Preferred Stock as provided in paragraph (a) above
  immediately after it declares a dividend or distribution on the Common Stock
  (other than a dividend payable in shares of Common Stock); provided that, in
  the event no dividend or distribution shall have been declared on the Common
  Stock during the period between any Series A Quarterly Dividend Payment Date
  and the next subsequent Series A Quarterly Dividend Payment Date, a dividend
  of $10.00 per share on the Series A Junior Participating Preferred Stock shall
  nevertheless be payable on such subsequent Series A Quarterly Dividend Payment
  Date.

  (c) Dividends shall begin to accrue and be cumulative on outstanding shares of
  Series A Junior Participating Preferred Stock from the Series A Quarterly
  Dividend Payment Date next preceding the date of issue of such shares of
  Series A Junior Participating Preferred Stock, unless the date of issue of
  such shares is prior to the record date for the first Series A Quarterly
  Dividend Payment Date, in which case dividends on such shares shall begin to
  accrue from the date of issue of such shares, or unless the date of issue is a
  Series A Quarterly Dividend Payment Date or is a date after the record date
  for the determination of holders of shares of Series A Junior Participating
  Preferred Stock entitled to receive a quarterly dividend and before such
  Series A Quarterly Dividend Payment Date, in either of which events such


                                       4

 
  dividends shall begin to accrue and be cumulative from such Series A Quarterly
  Dividend Payment Date. Accrued but unpaid dividends shall not bear interest.
  Dividends paid on the shares of Series A Junior Participating 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. The Board of Directors
  may fix a record date for the determination of holders of shares of Series A
  Junior Participating Preferred Stock entitled to receive payment of a dividend
  or distribution declared thereon, which record date shall be no more than 30
  days prior to the date fixed for the payment thereof.

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

  (a) Subject to the provision for adjustment hereinafter set forth, each share
  of Series A Junior Participating Preferred Stock shall entitle the holder
  thereof to 100 votes on all matters submitted to a vote of the stockholders of
  the Corporation. In the event the Corporation shall at any time after the
  Rights Declaration Date (i) declare any dividend on Common Stock payable in
  shares of Common Stock, (ii) subdivide the outstanding Common Stock, or (iii)
  combine the outstanding Common Stock into a smaller number of shares, then in
  each such case the number of votes per share to which holders of shares of
  Series A Junior Participating Preferred Stock were entitled immediately prior
  to such event shall be adjusted by multiplying such number by a fraction the
  numerator of which is the number of shares of Common Stock outstanding
  immediately after such event and the denominator of which is the number of
  shares of Common Stock that were outstanding immediately prior to such event.

  (b) Except as otherwise provided herein or by law, the holders of shares of
  Series A Junior Participating Preferred Stock and the holders of shares of
  Common Stock shall vote together as one class on all matters submitted to a
  vote of stockholders of the Corporation.

  (c) (i) If at any time dividends on any Series A Junior Participating
      Preferred Stock shall be in arrears in an amount equal to six (6)
      quarterly dividends thereon, the occurrence of such contingency shall mark
      the beginning of a period (herein called a "default period") which shall
      extend until such time when all accrued and unpaid dividends for all
      previous quarterly dividend periods and for the current quarterly dividend
      period on all shares of Series A Junior Participating Preferred Stock then
      outstanding shall have been declared and paid or set apart for payment.
      During each default period, all holders of Series Preferred Stock,
      (including holders of the Series A Junior Participating Preferred Stock)
      with dividends in arrears in an amount equal to six (6) quarterly
      dividends thereon, voting as a class, irrespective of series, shall have
      the right to elect two (2) Directors.

     (ii) During any default period, such voting right of the holders of Series
     A Junior Participating Preferred Stock may be exercised initially at a
     special meeting called pursuant to subparagraph (iii) of this Section 3(c)
     or at any annual meeting of stockholders, and thereafter at annual meetings
     of stockholders, provided that neither such voting right nor the right of
     the holders of any other series of Series Preferred Stock, if any, to
     increase, in certain cases, the authorized number of Directors shall be
     exercised unless the holders of ten percent (10%) in number of shares of
     Series Preferred Stock outstanding shall be present in person or by proxy.
     The absence of a quorum of the holders of Common Stock shall not affect the
     exercise by the holders of Series Preferred Stock of such voting right. At
     any meeting at which the holders of Series Preferred Stock shall exercise
     such voting right initially during an existing default period, they shall
     have the right, voting as a class, to elect Directors to fill such
     vacancies, if any, in the Board of Directors as may then exist up to two
     (2) Directors or, if such right is exercised at an annual meeting, to elect
     two (2)


                                       5

 
     Directors. If the number which may be so elected at any special meeting
     does not amount to the required number, the holders of the Series Preferred
     Stock shall have the right to make such increase in the number of Directors
     as shall be necessary to permit the election by them of the required
     number. After the holders of the Series Preferred Stock shall have
     exercised their right to elect Directors in any default period and during
     the continuance of such period, the number of Directors shall not be
     increased or decreased except by vote of the holders of Series Preferred
     Stock as herein provided or pursuant to the rights of any equity securities
     ranking senior to or pari passu with the Series A Junior Participating
                          ---- -----                                       
     Preferred Stock.

     (iii) Unless the holders of Series Preferred Stock shall, during an
     existing default period, have previously exercised their right to elect
     Directors, the Board of Directors may order, or any stockholder or
     stockholders owning in the aggregate not less than ten percent (10%) of the
     total number of shares of Series Preferred Stock outstanding, irrespective
     of series, may request, the calling of a special meeting of the holders of
     Series Preferred Stock, which meeting shall thereupon be called by the
     President, a Vice-President or the Secretary of the Corporation. Notice of
     such meeting and of any annual meeting at which holders of Series Preferred
     Stock are entitled to vote pursuant to this paragraph (c)(iii) shall be
     given to each holder of record of Series Preferred Stock by mailing a copy
     of such notice to him at his last address as the same appears on the books
     of the Corporation. Such meeting shall be called for a time not earlier
     than 20 days and not later than 60 days after such order or request or in
     default of the calling of such meeting within 60 days after such order or
     request, such meeting may be called on similar notice by any stockholder or
     stockholders owning in the aggregate not less than ten percent (10%) of the
     total number of shares of Series Preferred Stock outstanding.
     Notwithstanding the provisions of this paragraph (c)(iii), no such special
     meeting shall be called during the period within 60 days immediately
     preceding the date fixed for the next annual meeting of the stockholders.

     (iv) In any default period, the holders of Common Stock, and other classes
     of stock of the Corporation if applicable, shall continue to be entitled to
     elect the whole number of Directors until the holders of Series Preferred
     Stock shall have exercised their right to elect two (2) Directors voting as
     a class, after the exercise of which right (A) the Directors so elected by
     the holders of Series Preferred Stock shall continue in office until their
     successors shall have been elected by such holders or until the expiration
     of the default period, and (B) any vacancy in the Board of Directors may
     (except as provided in paragraph (c)(ii) of this Section 3) be filled by
     vote of a majority of the remaining Directors theretofore elected by the
     holders of the class of stock which elected the Director whose office shall
     have become vacant. References in this paragraph (c) to Directors elected
     by the holders of a particular class of stock shall include Directors
     elected by such Directors to fill vacancies as provided in clause (B) of
     the preceding sentence.

     (v) Immediately upon the expiration of a default period, (A) the right of
     the holders of Series Preferred Stock as a class to elect Directors shall
     cease, (B) the term of any Directors elected by the holders of Series
     Preferred Stock as a class shall terminate, and (C) the number of Directors
     shall be such number as may be provided for in this Certificate of
     Incorporation or the By-laws of the Corporation irrespective of any
     increase made pursuant to the provisions of paragraph (c)(ii) of this
     Section 3 (such number being subject, however, to change thereafter in any
     manner provided by law or in this Certificate of Incorporation or the By-
     laws of the Corporation). Any vacancies in the Board of Directors effected
     by the provisions of clauses (B) and (C) in the preceding sentence may be
     filled by a majority of the remaining Directors.


                                       6

 
  (d) Except as set forth herein or as otherwise required by applicable law,
  holders of Series A Junior Participating 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 taking any corporate action.

4.  Certain Restrictions.

  (a) Whenever quarterly dividends or other dividends or distributions payable
  on the Series A Junior Participating 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 Junior
  Participating Preferred Stock outstanding shall have been paid in full, the
  Corporation 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 Junior Participating 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 Junior
     Participating Preferred Stock, except dividends paid ratably on the Series
     A Junior Participating 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 Junior Participating Preferred
     Stock, provided that the Corporation may at any time redeem, purchase or
     otherwise acquire shares of any such parity stock in exchange for shares of
     any stock of the Corporation ranking junior (either as to dividends or upon
     dissolution, liquidation or winding up) to the Series A Junior
     Participating Preferred Stock;

     (iv) purchase or otherwise acquire for consideration any shares of Series A
     Junior Participating Preferred Stock, or any shares of stock ranking on a
     parity with the Series A Junior Participating 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 Corporation shall not permit any subsidiary of the Corporation to
  purchase or otherwise acquire for consideration any shares of stock of the
  Corporation unless the Corporation could, under paragraph (a) of this Section
  4, purchase or otherwise acquire such shares at such time and in such manner.

5.  Reacquired Shares. Any shares of Series A Junior Participating Preferred
Stock purchased or otherwise acquired by the Corporation in any manner
whatsoever shall be retired and cancelled promptly after the acquisition
thereof. All such shares shall upon their cancellation become authorized but
unissued shares of Series Preferred Stock and may be reissued as part of a new
series of Series Preferred Stock to be created by resolution or resolutions of
the Board of Directors, subject to the conditions and restrictions on issuance
set forth herein.

                                       7

 
6.  Liquidation, Dissolution or Winding Up.

  (a) Upon any liquidation (voluntary or otherwise), dissolution or winding up
  of the Corporation, no distribution shall be made to the holders of shares of
  stock ranking junior (either as to dividends or upon liquidation, dissolution
  or winding up) to the Series A Junior Participating Preferred Stock unless,
  prior thereto, the holders of shares of Series A Junior Participating
  Preferred Stock shall have received $100 per share, plus an amount equal to
  accrued and unpaid dividends and distributions thereon, whether or not
  declared, to the date of such payment (the "Series A Liquidation Preference").
  Following the payment of the full amount of the Series A Liquidation
  Preference, no additional distributions shall be made to the holders of shares
  of Series A Junior Participating Preferred Stock unless, prior thereto, the
  holders of shares of Common Stock shall have received an amount per share (the
  "Common Adjustment") equal to the quotient obtained by dividing (i) the Series
  A Liquidation Preference by (ii) 100 (as appropriately adjusted as set forth
  in subparagraph C below to reflect such events as stock splits, stock
  dividends and recapitalizations with respect to the Common Stock) (such number
  in clause (ii), the "Adjustment Number"). Following the payment of the full
  amount of the Series A Liquidation Preference and the Common Adjustment in
  respect of all outstanding shares of Series A Junior Participating Preferred
  Stock and Common Stock, respectively, holders of Series A Junior Participating
  Preferred Stock and holders of shares of Common Stock shall receive their
  ratable and proportionate share of the remaining assets to be distributed in
  the ratio of the Adjustment Number to 1 with respect to such Preferred Stock
  and Common Stock, on a per share basis, respectively.

  (b) In the event, however, that there are not sufficient assets available to
  permit payment in full of the Series A Liquidation Preference and the
  liquidation preferences of all other series of preferred stock, if any, which
  rank on a parity with the Series A Junior Participating Preferred Stock, then
  such remaining assets shall be distributed ratably to the holders of such
  parity shares in proportion to their respective liquidation preferences. In
  the event, however, that there are not sufficient assets available to permit
  payment in full of the Common Adjustment, then such remaining assets shall be
  distributed ratably to the holders of Common Stock.

  (c) In the event the Corporation shall at any time after the Rights
  Declaration Date (i) declare any dividend on Common Stock payable in shares of
  Common Stock, (ii) subdivide the outstanding Common Stock, or (iii) combine
  the outstanding Common Stock into a smaller number of shares, then in each
  such case the Adjustment Number in effect immediately prior to such event
  shall be adjusted by multiplying such Adjustment Number by a fraction the
  numerator of which is the number of shares of Common Stock outstanding
  immediately after such event and the denominator of which is the number of
  shares of Common Stock that were outstanding immediately prior to such event.

7.  Consolidation, Merger, etc. In case the Corporation 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
and/or any other property, then in any such case the shares of Series A Junior
Participating Preferred Stock shall at the same time be similarly exchanged or
changed in an amount per share (subject to the provision for adjustment
hereinafter set forth) equal to 100 times the aggregate amount of stock,
securities, cash and/or any other property (payable in kind), as the case may
be, into which or for which each share of Common Stock is changed or exchanged.
In the event the Corporation shall at any time after the Rights Declaration Date
(a) declare any dividend on Common Stock payable in shares of Common Stock, (b)
subdivide the outstanding Common Stock, or (c) combine the outstanding Common
Stock into a smaller number of shares, then in each such case the amount set
forth in the preceding sentence with respect to the exchange or change of shares
of Series A Junior Participating Preferred Stock shall be adjusted by
multiplying such amount by a fraction the numerator of which is the number of

                                       8

 
shares of Common Stock outstanding immediately after such event and the
denominator of which is the number of shares of Common Stock that were
outstanding immediately prior to such event.

8.  No Redemption. The shares of Series A Junior Participating Preferred Stock
shall not be redeemable.

9.  Ranking. The Series A Junior Participating Preferred Stock shall rank junior
to all other series of the Corporation's Series Preferred Stock as to the
payment of dividends and the distribution of assets, unless the terms of any
such series shall provide otherwise.

10. Amendment. This Certificate of Incorporation shall not be further amended
in any manner which would materially alter or change the powers, preferences or
special rights of the Series A Junior Participating Preferred Stock so as to
affect them adversely without the affirmative vote of the holders of two-thirds
or more of the outstanding shares of Series A Junior Participating Preferred
Stock, voting separately as a class.

11. Fractional Shares.  Series A Junior Participating Preferred Stock may be
issued in fractions of a share which shall entitle the holder, in proportion to
such holder's fractional shares, to exercise voting rights, receive dividends,
participate in distributions and to have the benefit of all other rights of
holders of Series A Junior Participating Preferred Stock.


II. COMMON STOCK

A.  Dividends.  Subject to all of the rights of the Series Preferred Stock,
dividends may be paid upon the Common Stock as and when declared by the Board of
Directors out of funds legally available for the payment of dividends.

B.  Liquidation Rights.  In the event of any liquidation, dissolution or
winding-up of the Corporation, whether voluntary or involuntary, and after the
holders of the Series Preferred Stock shall have been paid in full amounts to
which they respectively shall be entitled, or an amount sufficient to pay the
aggregate amount to which such holders shall be entitled shall have been
deposited in trust with a bank or trust company having its principal office in
the Borough of Manhattan, City, County and State of New York, having a capital,
undivided profits and surplus aggregating at least $5,000,000, for the benefit
of the holders of the Series Preferred Stock, the remaining net assets of the
Corporation shall be distributed pro rata to the holders of the Common Stock.

C.  Voting Rights.  Except as otherwise expressly provided with respect to the
Series Preferred Stock and except as otherwise may be required by law, the
Common Stock shall have the exclusive right to vote for the election of
directors and for all other purposes and each holder of Common Stock shall be
entitled to one vote for each share held.


                                  ARTICLE V.

A.  Board of Directors of the Corporation.

1.  General Provisions.  The business and affairs of the Corporation shall be
managed under the direction of the Board of Directors. The exact number of
directors shall be fixed from time to time by, or in the manner provided in, the
By-Laws of the Corporation and may be increased or

                                       9

 
decreased as therein provided. Directors of the Corporation need not be elected
by ballot unless required by the By-laws.

2.  Classification of Board of Directors.  The directors shall be divided into
three classes. Each such class shall consist, as nearly as may be possible, of
one-third of the total number of directors, and any remaining directors shall be
included within such group or groups as the Board of Directors shall designate.
At the annual meeting of stockholders in 1994, a class of directors shall be
elected for a one-year term, a class of directors for a two-year term and a
class of directors for a three-year term. At each succeeding annual meeting of
stockholders, beginning in 1995, successors to the class of directors whose term
expires at that annual meeting shall be elected for a three-year term. If the
number of directors is changed, any increase or decrease shall be apportioned
among the classes so as to maintain the number of directors in each class as
nearly equal as possible, but in no case shall a decrease in the number of
directors shorten the term of any incumbent director.  A director may be removed
from office for cause only and, subject to such removal, death, resignation,
retirement or disqualification, shall hold office until the annual meeting for
the year in which his term expires and until his successor shall be elected and
qualify. No alteration, amendment or repeal of this Article V or the By-Laws of
the Corporation shall be effective to shorten the term of any director holding
office at the time of such alteration, amendment or repeal, to permit any such
director to be removed without cause, or to increase the number of directors in
any class or in the aggregate from that existing at the time of such alteration,
amendment or repeal until the expiration of the terms of office of all directors
then holding office, unless (i) in the case of this Article V, such alteration,
amendment or repeal has been approved by the holders of all shares of stock
entitled to vote thereon, or (ii) in the case of the By-Laws, such alteration,
amendment or repeal has been approved by either the holders of all shares
entitled to vote thereon or by a vote of a majority of the entire Board of
Directors.

3.  Directors Appointed by a Specific Class of Stockholders.  To the extent that
any holders of any class or series of stock other than Common Stock issued by
the Corporation shall have the separate right, voting as a class or series, to
elect directors, the directors elected by such class or series shall be deemed
to constitute an additional class of directors and shall have a term of office
for one year or such other period as may be designated by the provisions of such
class or series providing such separate voting right to the holders of such
class or series of stock, and any such class of directors shall be in addition
to the classes designated above.


                                  ARTICLE VI.

A.  General Provisions.  The following provisions are hereby adopted for the
purpose of defining, limiting and regulating the powers of the Corporation and
of its directors and stockholders:

1.  Amendments to the Certificate of Incorporation.  Subject to the provisions
of applicable law, the Corporation reserves the right from time to time to make
any amendment to its Certificate of Incorporation, now or hereafter authorized
by law, including any amendment which alters the contract rights as expressly
set forth therein, of any outstanding stock.

2.  Amendments to the By-Laws.  The Board of Directors is expressly authorized
to adopt, alter and repeal the By-Laws of the Corporation in whole or in part at
any regular or special meeting of the Board of Directors, by vote of a majority
of the entire Board of Directors. Except where this Certificate of Incorporation
otherwise requires a higher vote, the By-Laws may also be adopted, altered or
repealed in whole or in part at any annual or special meeting of the
stockholders by the affirmative vote of three-fourths of the shares of the
Corporation outstanding and entitled to vote thereon.

                                      10

 
3.  No Preemptive Rights.  No holder of any class of stock of the Corporation,
whether now or hereafter authorized or outstanding, shall have any preemptive,
preferential or other right to subscribe for or purchase any class of the
Corporation's stock, whether now or hereafter authorized or outstanding, which
it may at any time issue or sell, or to subscribe for or purchase any notes,
debentures, bonds or other securities which it may at any time issue or sell,
whether or not the same be convertible into or exchangeable for or carry options
or warrants to purchase shares of any class of the Corporation's stock or other
securities, or to receive or purchase any warrants or options which may be
issued or granted evidencing the right to purchase any such stock or other
securities, it being intended by this Section 3 that all preemptive rights of
any kind applicable to securities of the Corporation are eliminated.

4.  Vote Required to Take Action; Action by Written Consent.  Except as
otherwise provided in this Certificate of Incorporation and except as otherwise
provided by applicable law, the Corporation may take or authorize any action
upon the affirmative vote of the majority of shares present in person or
represented by proxy at the meeting and entitled to vote on the subject matter
thereof. Action shall be taken by stockholders of the Corporation only at annual
or special meetings of stockholders, and stockholders may act in lieu of a
meeting only by unanimous written consent.

5.  Compensation of Directors.  The Board of Directors may determine from time
to time the amount and type of compensation which shall be paid to its members
for service on the Board of Directors. The Board of Directors shall also have
the power, in its discretion, to provide for and to pay to directors rendering
services to the Corporation not ordinarily rendered by directors, as such,
special compensation appropriate to the value of such services, as determined by
the Board from time to time.

6.  Interested Transactions.  Any director or officer individually, or any
partnership of which any director or officer may be a member, or any corporation
or association of which any director or officer may be an officer, director,
trustee, employee or stockholder, may be a party to, or may be pecuniarily or
otherwise interested in, any contract or transaction of the Corporation, and in
the absence of fraud no contract or other transaction shall be thereby affected
or invalidated. Any director of the Corporation who is so interested, or who is
also a director, officer, trustee, employee or stockholder of such other
corporation or association or a member of such partnership which is so
interested, may be counted in determining the existence of a quorum at any
meeting of the Board of Directors of the Corporation which shall authorize any
such contract or transaction, and may vote thereat to authorize any such
contract or transaction, with like force and effect as if he were not such
director, officer, trustee, employee or stockholder of such other corporation or
association or not so interested or a member of a partnership so interested;
provided that in case a director, or a partnership, corporation or association
- --------                                                                      
of which a director is a member, officer, director, trustee or employee is so
interested, such fact shall be disclosed or shall have been known to the Board
of Directors or a majority thereof. This paragraph shall not be construed to
invalidate any such contract or transaction which would otherwise be valid under
the common and statutory law applicable thereto.

7.  Indemnification.  The Corporation shall indemnify (a) its directors to the
fullest extent permitted by the laws of the State of Delaware now or hereafter
in force, including the advancement of expenses under the procedures provided by
such laws, (b) all of its officers to the same extent as it shall indemnify its
directors, and (c) its officers who are not directors to such further extent as
shall be authorized by the Board of Directors and be consistent with law.
Subject only to any limitations prescribed by the laws of the State of Delaware
now or hereafter in force, the foregoing shall not limit the authority of the
Corporation to indemnify the directors, officers and other employees and agents
of this Corporation consistent with law and shall not be deemed to be exclusive
of any rights to which those indemnified may be entitled as a matter of law or
under any resolution, By-Law provision, or agreement.

                                      11

 
8.  Court-Ordered Meetings of Creditors and/or Stockholders.  Whenever a
compromise or arrangement is proposed between this Corporation and its creditors
or any class of them and/or between this Corporation and its stockholders or any
class of them, any court of equitable jurisdiction within the State of Delaware
may, on the application in a summary way of this Corporation or of any creditor
or stockholder thereof, or on the application of any receiver or receivers
appointed for this Corporation under the provisions of Section 291 of Title 8 of
the Delaware Code or on the application of trustees in dissolution or of any
receiver or receivers appointed for this Corporation under the provisions of
Section 279 of Title 8 of the Delaware Code order a meeting of the creditors or
class of creditors, and/or of the stockholders or class of stockholders of this
Corporation, as the case may be, to be summoned in such manner as such court
directs. If a majority in number representing three-fourths in value of the
creditors or class of creditors, and/or of the stockholders or class of
stockholders of this Corporation, as the case may be, agree to any compromise or
arrangement and to any reorganization of this Corporation as a consequence of
such compromise or arrangement, the said compromise or arrangement and the said
reorganization shall, if sanctioned by the court to which such application has
been made, be binding on all the creditors or class of creditors, and/or on all
the stockholders or class of stockholders, of this Corporation, as the case may
be, and also on this Corporation.

9.  Liability of Directors.  To the fullest extent permitted by Delaware
statutory or decisional law, as amended or interpreted, no director of this
Corporation shall be personally liable to the Corporation or its stockholders
for monetary damages for breach of fiduciary duty as a director. This Section 9
does not affect the availability of equitable remedies for breach of fiduciary
duties.


                                  ARTICLE VII.

       Business Combination; or (y) in the transaction in which it became an
       Interested Stockholder, whichever is higher; or

       (B) The Market Value per share of common stock of the same class or
       series on the Announcement Date or on the Determination Date, whichever
       is higher; or

       (C) The price per share equal to the Market Value per share of common
       stock of the same class or series determined pursuant to subparagraph
       (i)(B) of this paragraph (a), multiplied by the fraction of: (x) the
       highest per share price (including any brokerage commissions, transfer
       taxes and soliciting dealers' fees) paid by the Interested Stockholder
       for any shares of common stock of the same class or series acquired by it
       within the 2 year period immediately prior to the Announcement Date, over
       (y) the Market Value per share of common stock of the same class or

     outstanding stock is to be in cash or in the same form as the Interested
     Stockholder has previously paid for shares of the same class or series of
     stock. If the Interested Stockholder has paid for shares of any class of
     stock with varying forms of consideration, the form of consideration for
     such class of stock shall be either cash or the form used to acquire the
     largest number of shares of such class or series of stock previously
     acquired by it.


                                      13

       dividends paid on any class or series of stock of the Corporation that is
       not preferred stock (except as necessary to reflect any subdivision of
       the stock); (y) an increase in such annual rate of dividends as necessary
       to reflect any reclassification (including any reverse stock split),
       recapitalization, reorganization or any similar transaction which has the
       effect of reducing the number of outstanding shares of the stock; and (z)
       the Interested Stockholder did not become the beneficial owner of any
       additional shares of stock of the Corporation except as part of the
       transaction which resulted in such Interested Stockholder becoming an
       Interested Stockholder or by virtue of proportionate stock splits or
       stock dividends.

       (B) The provisions of subparagraphs (x) and (y) of subparagraph (iv)(A)
       do not apply if no Interested Stockholder or an Affiliate or Associate of
       the Interested Stockholder voted as a director of the Corporation in a
       manner inconsistent with such sub-subparagraphs and the Interested
       Stockholder, within 10 days after any act or failure to act inconsistent
       with such sub-subparagraphs, notifies the Board of Directors of the
       Corporation in writing that the Interested Stockholder disapproves
       thereof and requests in good faith that the Board of Directors rectify
       such act or failure to act.

     (v) After the Interested Stockholder has become an Interested Stockholder,
     the Interested Stockholder may not have received the benefit, directly or
