                          CERTIFICATE OF INCORPORATION
                                       OF
                              MCKESSON CORPORATION
                    ORIGINALLY INCORPORATED ON JULY 7, 1994
                      UNDER THE NAME OF SP VENTURES, INC.
                                (RESTATES ONLY)



                                   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 1013 Centre Road, City of Wilmington 19805-1297, County of New
Castle.  The name of the registered agent of the Corporation at such address is
The Prentice-Hall Corporation System, Inc.


                                  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 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.

   (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.

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
   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) 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.

   (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.

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

                                   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 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.

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.

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.

VII) shall be recommended by the Board of Directors and approved by the

          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

          Date, over (y) the Market Value per share of common stock of the same
          class or series on the first day in such 2 year period on which the
          Interested Stockholder acquired any shares of common stock.

      (ii) The aggregate amount of the cash and the Market Value as of the
      Valuation Date of consideration other than cash to be received per share
      by holders of shares of any class or series of outstanding stock other

          (C) The Market Value per share of such class of stock on the
          Announcement Date or on the Determination Date, whichever is higher;

      of outstanding stock is to be in cash or in the same form as the

      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

          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

      Subsidiaries, whether in anticipation of or in connection with such
      Business Combination or otherwise.

   (b) The requirements of Section 1 of this Article VII do not apply to
   Business Combinations that, as to specifically identified Interested
   Stockholders or their Affiliates, have been approved or exempted therefrom by
   resolution of the Board of Directors of the Corporation at any time prior to
   the time that the Interested Stockholder first became an Interested
   Stockholder. If the Board of Directors so provides, the resolution shall be
   subject to approval of the stockholders in the 

 
   manner and by the vote specified in the resolution.
