               SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS
 
  Certain of the matters discussed under the captions "Risk Factors,"
"Financial Review," "The Company" and elsewhere in this Prospectus or in the
information incorporated by reference herein may constitute forward-looking
statements within the meaning of the Private Securities Litigation Reform Act
of 1995 and as such may involve known and unknown risks, uncertainties and
other factors that may cause the actual results, performance or achievements
of McKesson to be materially different from any future results, performance or
achievements expressed or implied by such forward-looking statements. Given
these uncertainties, prospective investors are cautioned not to place undue
reliance on such statements. McKesson also undertakes no obligation to update
these forward-looking statements.
 
                                 RISK FACTORS
 
  Risks Generally Associated with Acquisitions. An element of the Company's
growth strategy is to pursue strategic acquisitions that either expand or
complement the Company's business. Acquisitions involve a number of special
risks, including the diversion of management's attention to the assimilation
of the operations from other business concerns, difficulties in the
integration of operations and systems, the assimilation and retention of the
personnel of the acquired companies, challenges in retaining the acquired
businesses' customers and potential adverse short-term effects on the
Company's operating results. In addition, the Company may require additional
debt or equity financing for future acquisitions, which may not be available
on terms favorable to the Company, if at all. The inability of the Company to
successfully finance, complete and integrate strategic acquisitions in a
timely manner could have an adverse impact on the Company's results of
operations and its ability to effect a portion of its growth strategy.
 
  Changing United States Healthcare Environment. In recent years, the
healthcare industry has undergone significant change driven by various efforts
to reduce costs, including potential national healthcare reform, trends toward
managed care, cuts in Medicare, consolidation of pharmaceutical and
medical/surgical supply distributors and the development of large,
sophisticated purchasing groups. The Company cannot predict whether any
healthcare reform efforts will be enacted and what effect or to what extent
any such reforms may have on the Company, its practices and products or its
customers and suppliers. Changes in governmental support of healthcare
services, the method by which such services are delivered, the prices for such
services or other legislation or regulations governing such services or
mandated benefits may have a material adverse effect on the Company's results
of operations.

                                  THE COMPANY
 
  McKesson is the largest health care supply management company in
North America. The Company also develops and manages innovative marketing
programs for drug manufacturers and, through McKesson Water Products Company,
processes and markets pure drinking water.
 
  The Company's objective is to become the world leader in health care supply
and comprehensive pharmaceutical management across the entire supply chain,
from manufacturer to patient. In pursuit of this goal, the Company has
completed a number of acquisitions in its core health care business. Since
late 1995, the Company has acquired General Medical Inc. ("General Medical"),
a leading distributor of medical and surgical supplies to the acute care,
physician care and extended care markets, the drug distribution business of
FoxMeyer Corporation ("FoxMeyer"), Automated Healthcare, Inc. ("AHI"), a
manufacturer of automated drug dispensing equipment for hospitals, and Ogden
BioServices Corporation (now "McKesson Bioservices Corporation"), a provider
of support services to government and commercial organizations engaged in drug
research and development.
 
  The Company conducts its operations through two operating business segments
which generated annual sales in fiscal 1996 of $9.95 billion, approximately
97% of which were generated by the Health Care Services segment and
approximately 3% of which were generated primarily by McKesson's Water
Products (as hereinafter defined) business. In fiscal 1996, operating profits
for the Health Care Services business and the Water Products business were
$206.1 million and $39.6 million, respectively.
 
  The principal executive offices of the Company are located at McKesson
Plaza, One Post Street, San Francisco, California 94104, and the telephone
number is (415) 983-8300.
 
RECENT ACQUISITIONS AND DISPOSITIONS
 
  McKesson has recently undertaken several initiatives to further focus the
Company on its core health care business:
 
  .  In March 1997, McKesson disposed of Millbrook Distribution Services Inc.
     ("Millbrook") for an amount on an after-tax basis which approximates
     Millbrook's book value. Millbrook is reflected as a discontinued
     operation in the Company's financial statements. Millbrook is engaged in
     distributing health and beauty care products, general merchandise, and
     specialty foods to retail stores.
 
  .  In February 1997, McKesson acquired General Medical, the largest multi-
     market distributor of medical and surgical supplies, for $775 million.
 
  .  In December 1996, the Company disposed of its 55% equity interest in
     Armor All Products Corporation ("Armor All"), a non-health care business.
 
  .  In November 1996, the Company acquired FoxMeyer out of bankruptcy for
     approximately $600 million.
 
  .  In April 1996, the Company acquired AHI, a business that specializes in
     centralized robotic pharmaceutical dispensing systems for hospitals, for
     $65 million.
 
  .  In December 1995, the Company acquired McKesson Bioservices Corporation,
     a business that provides product marketing and support services for the
     pharmaceutical industry, for approximately $20 million.
 
MCKESSON HEALTH CARE SERVICES
 
  Through its Health Care Services segment, the Company is the largest
distributor of ethical and proprietary drugs and health and beauty care
products in North America, generating approximately 84% of the Company's
operating profits from continuing operations in fiscal 1996. The Company is
the market leader in its core U.S. drug distribution business. U.S. health
care operations also include Healthcare Delivery Systems, Inc. ("HDS") and
McKesson Bioservices Corporation, through which the Company provides marketing
and other support services to drug manufacturers, AHI, a business that
specializes in automated pharmaceutical dispensing systems for hospitals, and
Zee Medical, Inc., a distributor of first-aid products and supplies to
industrial and commercial customers. International operations include Medis
Health and Pharmaceutical Services Inc., a wholly-owned subsidiary and the
largest drug distributor in Canada, and the Company's 22.7% equity interest in
Nadro, S.A. de C.V., the largest drug distributor in Mexico.
 
  The Company's domestic distribution operations supply drugs and health and
beauty care products to independent and chain drug stores, hospitals,
alternate-site facilities, food stores and mass merchandisers in all
 
                                       4

50 states. Using the names "Economost" and "Econolink" and a number of related
service marks, the Company has promoted electronic order entry systems and a
wide range of computerized merchandising and asset management services for
drug retailers and hospitals. The Company also supplies computer-based
practice management systems to drug retailers. The Company believes that its
financial strength, purchasing leverage, nationwide network of distribution
centers, and advanced logistics and information technologies provide
competitive advantages to its drug distribution operations. For example, the
Company uses Acumax(R), a computerized bar-code scanning system, to track
items in its warehouses. Acumax enables the Company to achieve order filling
and inventory accuracy levels of more than 99%, ensuring that the right
product arrives at the right time and place for both the Company's customers
and their patients.
 
  Health Care Services serves three primary customer segments: retail
independent pharmacies, retail chains and institutional providers (including
hospitals, health care facilities and pharmacy service operators) which
represented approximately 41%, 30%, and 21%, respectively, of U.S. Health Care
Services revenues for fiscal 1996. A fourth customer category is
pharmaceutical manufacturers, which is managed by McKesson's Pharmaceutical
and Retail Services Business group.
 
    INDEPENDENT PHARMACIES. In addition to distribution services, the Company
  provides value added services to independent retail pharmacies through
  management information systems, including inventory management, electronic
  billing, current pricing and other financial management offerings. In
  February 1996, McKesson launched the OmniLinkSM centralized pharmacy
  technology platform and the associated CareMaxSM network of independent
  pharmacies. The combined offering links independent pharmacies, creating a
  "virtual chain" for contracting with pharmaceutical suppliers and managed
  care organizations. As of December 31, 1996, OmniLink had been installed in
  over 1,600 pharmacies.
 
    OmniLink offers pharmacies streamlined transaction processing through
  OmniLink's connectivity with managed care organizations, while promoting
  compliance with managed care formularies and appropriate reimbursement from
  managed care plans. The service also improves cash flow for pharmacies and
  enhances pharmacy revenues through programs such as 24-hour advanced
  funding of third-party reimbursements, prescription refill reminders,
  patient direct marketing and distribution of coupons and samples for over-
  the-counter products.
 
    The Company currently has two pharmacy programs for independent
  pharmacies--Valu-Rite(R), a voluntary cooperative program, and Health
  Mart(R), a franchise program. Through Valu-Rite, the Company provides its
  independent U.S. retail drug store customers with a common marketing
  identity, group advertising, purchasing programs, promotional merchandise
  and access to a pharmacy provider network. At December 31, 1996, over 5,200
  stores were participating in the Valu-Rite program. Through Health Mart,
  acquired as part of FoxMeyer, the Company provides its community
  pharmacists with a franchise program. Currently, Health Mart has
  approximately 700 franchisees. Together, Valu-Rite and Health Mart
  pharmacies comprise approximately 20% of the nation's independent retail
  pharmacies.
 
    RETAIL CHAINS. Retail drug chains do business with the Company in three
  ways: primary sourcing, secondary sourcing and dock-to-dock (warehousing).
  In primary sourcing, a chain depends on the Company to supply its
  logistics, warehousing and contract administration functions, much as the
  Company performs primary distribution for all other retail customers. In
  secondary sourcing, the Company "backs up" the chains' own warehouses with
  deliveries on an as-needed basis. In dock-to-dock, the Company transfers
  large-quantity (bulk) shipments from manufacturers to chains and provides
  billing services.
 
    INSTITUTIONAL BUSINESS. The Company, through its McKesson Health Systems
  unit, provides drug distribution services, and related logistics and
  management information systems support, to the institutional market, which
  includes hospitals, alternate-sites and integrated health networks. The
  acquisition of FoxMeyer strengthened the Company's position in the
  institutional marketplace. Similarly, the completion of the acquisition of
  General Medical further enhances the Company's competitiveness,
  particularly in the fast-growing alternate-site segment.
 
    MANUFACTURERS. Pharmaceutical and Retail Services develops innovative
  marketing and distribution services to build and sustain sales for
  manufacturers' pharmaceutical products. Through its HDS unit, this group
  operates integrated systems for specialized delivery of biotech and other
  high-cost pharmaceutical
 
                                       5
<PAGE>
 
  therapies. These systems manage manufacturer cost and information
  requirements through financial assistance programs for patients,
  reimbursement support and patient advocacy programs, product hot-lines,
  pharmacy-based sampling and physician and patient information programs.
  These services are also provided to manufacturers on a stand-alone basis
  outside of integrated service systems. Through McKesson Bioservices
  Corporation, this group also provides support services to commercial, non-
  profit and governmental organizations engaged in drug development and
  biomedical research including biological repository management, clinical
  trials support and regulatory process management services.
 
    McKesson also provides a key service to drug manufacturers with McKesson
  Select GenericsSM, an enhancement of the Company's Multi-Source Complete(R)
  generic drug program which was launched in May 1996. Through the Select
  Generics program, retail customers have access to a broad line of over
  1,300 generic items, and single suppliers are chosen for each item, thereby
  offering to manufacturers the advantage of exclusivity and compliance.
 
GENERAL MEDICAL ACQUISITION
 
  On February 21, 1997, McKesson acquired General Medical for approximately
$775 million, including $347 million for the equity, half in the Company's
Common Stock and half in cash, and the assumption of approximately $428
million in debt. The acquisition of General Medical extends the Company's
product line to include medical and surgical supplies in addition to the drugs
and health and beauty care products it currently distributes. The combination
of McKesson and General Medical creates a strong force to address the
increasingly complex clinical supply needs of physicians, extended-care
facilities and integrated health care networks.
 
  General Medical is the nation's leading supplier of medical-surgical
supplies to the full range of alternate-site health care facilities, including
physicians and clinics (primary care), long-term care and home-care sites
(extended care), and is the third largest distributor of medical-surgical
supplies to hospitals. In the year ended December 31, 1995, General Medical
had revenues of approximately $1.5 billion, of which 58% were derived from the
acute care market, 31% from primary care and 11% from extended care. In
addition to marketing to each market segment separately, General Medical
emphasizes sales to these three market segments through integrated health care
networks which operate health care facilities across the market spectrum.
 
  General Medical distributes a broad array of products, comprising
approximately 130,000 products supplied by over 4,000 medical and surgical
product manufacturers, through a 700-person sales force to more than
200,000 care providers nationwide, including 500 account managers calling on
physicians. Additionally, General Medical offers a variety of value-added
services to its customers, particularly in the area of cost containment and
inventory management. The acquisition of General Medical is a major step
forward in solidifying the Company's position as the world leader in health
care supply management.
 
FOXMEYER ACQUISITION
 
  Prior to its acquisition by the Company, FoxMeyer's drug distribution
business was the fourth largest in the United States. The acquisition of
FoxMeyer pairs the Company's financial capabilities and information technology
expertise with the substantial customer base of FoxMeyer and strengthens the
Company's position in all three customer segments (health care institutions,
retail independents and retail chains). The acquisition also gives the Company
access to new customers and opportunities for consolidation economics,
particularly cost reduction and distribution network reconfiguration.
 
MCKESSON WATER PRODUCTS COMPANY
 
  McKesson Water Products Company ("Water Products") is a leading provider in
the $3.4 billion bottled water industry in the United States. Except in the
State of Washington, it is the largest bottled water company in the geographic
markets in which it competes. In fiscal 1996, Water Products generated
approximately $40 million in pretax operating profit, and its operating margin
was 15%. Water Products is primarily engaged in the processing and sale of
bottled drinking water delivered to more than 500,000 homes and businesses
under its Sparkletts(R), Alhambra(R), and Crystal(TM) brands in California,
Arizona, Nevada, Oklahoma, Washington and Texas. It also sells packaged water
through retail stores in approximately 40 states.

                         DESCRIPTION OF CAPITAL STOCK
 
  The description of the Company's capital stock and of certain provisions of
Delaware law do not purport to be complete and are subject to and qualified in
their entirety by reference to the Company's Restated Certificate of
Incorporation (the "Certificate") and Restated By-Laws (the "By-Laws") and
Delaware law, and, with respect to certain rights of holders of shares of
Common Stock, the Rights Agreement (as hereinafter defined). Copies of such
documents have been filed with the Commission.
 
  As of the date hereof, the capital stock of McKesson consists of 200,000,000
authorized shares of Common Stock and 100,000,000 authorized shares of series
preferred stock.
 
COMMON STOCK
 
  As of March 31, 1997, there were 45,784,949 shares of Common Stock issued
and outstanding. The holders of outstanding shares of Common Stock are
entitled to receive dividends out of assets legally available therefor at such
times and in such amounts as the McKesson Board of Directors (the "Board") may
from time to time determine. The shares of Common Stock are neither redeemable
nor convertible, and the holders thereof have no preemptive or subscription
rights to purchase any securities of McKesson. Upon liquidation, dissolution
or winding up of McKesson, the holders of Common Stock are entitled to receive
the assets of McKesson, which are legally available for distribution, after
payment of all debts, other liabilities and any liquidation preferences of
outstanding preferred stock. Each outstanding share of Common Stock is
entitled to one vote on all matters submitted to a vote of stockholders. There
is no cumulative voting.
 
  In February 1997, McKesson Financing Trust issued an aggregate of 4,123,720
5% Trust Securities (each, a "Trust Security" and collectively, the "Trust
Securities"). Each Trust Security is convertible into Common Stock at any time
beginning May 21, 1997 and prior to the close of business on the business day
prior to June 1, 2027 (or prior to the date of redemption of the Trust
Security), at the option of the holder, at the rate of .6709 shares of Common
Stock for each Trust Security (equivalent to a conversion price of $74.53 per
share of Common Stock), subject to adjustment in certain circumstances.
 
SERIES PREFERRED STOCK
 
  As of March 31, 1997, there were no shares of series preferred stock issued
and outstanding. The Board is authorized to issue series preferred stock in
classes or series and to fix the designations, preferences, qualifications,
limitations, or restrictions of any class or series with respect to the rate
and nature of dividends, the price and terms and conditions on which shares
may be redeemed, the amount payable in the event of voluntary or involuntary
liquidation, the terms and conditions for conversion or exchange into any
other class or series of the stock, voting rights and other terms.
 
ANTI-TAKEOVER EFFECTS OF PROVISIONS OF THE COMPANY'S RESTATED CERTIFICATE OF
INCORPORATION AND BY-LAWS
 
  The Certificate and By-Laws of McKesson contain certain provisions that may
be deemed to have an anti-takeover effect and may delay, deter or prevent a
tender offer or takeover attempt that a stockholder might consider in its best
interest, including those attempts that might result in a premium over the
market price for the shares held by stockholders.
 
  Pursuant to the Certificate, the Board is divided into three classes serving
staggered three-year terms. Directors can be removed from office only for
cause and only by the affirmative vote of the holders of at least a majority
of the voting power of the then outstanding shares of any class or series of
capital stock of the Company entitled to vote generally in the election of
directors. Vacancies and newly created directorships on the Board may be
filled only by a majority of the remaining directors or by the plurality vote
of the stockholders.
 
  The Certificate also provides that any action required or permitted to be
taken by the holders of Common Stock may be effected only at an annual or
special meeting of such holders, and that stockholders may act in lieu of such
meetings only by unanimous written consent. The By-Laws provide that special
meetings of holders of Common Stock may be called only by the Chairman or the
President of the Company or the Board. Holders of Common Stock are not
permitted to call a special meeting or to require that the Board call a
special meeting of stockholders.
 
                                       8
<PAGE>
 
  The By-Laws establish an advance notice procedure for the nomination, other
than by or at the direction of the Board, of candidates for election as
directors as well as for other stockholder proposals to be considered at
annual meetings of stockholders. In general, notice of intent to nominate a
director or raise business at such meetings must be received by the Company
not less than 60 nor more than 90 days prior to the date of the annual meeting
and must contain certain specified information concerning the person to be
nominated or the matters to be brought before the meeting and concerning the
stockholder submitting the proposal.
 
  The Certificate also provides that certain provisions of the By-Laws may
only be amended by the affirmative vote of the holders of 75% of the shares of
the Company outstanding and entitled to vote. The Certificate also provides
that, in addition to any affirmative vote required by law, the affirmative
vote of holders of 80% of the voting stock of the Company and two-thirds of
the voting stock other than voting stock held by an interested stockholder
shall be necessary to approve certain business combinations proposed by an
interested stockholder.
 
  The foregoing summary is qualified in its entirety by the provisions of the
Certificate and By-Laws, copies of which have been filed with the Commission.
 
RIGHTS PLAN
 
  Pursuant to the Company's Rights Agreement (as defined below), the Board
declared a dividend distribution of one right (a "Right") for each outstanding
share of Common Stock to stockholders of record of the Company at November 1,
1994 (the "Record Date"). Each Right entitles the registered holder to
purchase from the Company a unit consisting of one one-hundredth of a share of
Series A Junior Participating Preferred Stock (the "Series A Preferred Stock")
at a purchase price of $100 per unit. The terms of the Rights are set forth in
a Rights Agreement between the Company and a Rights Agent (the "Rights
Agreement"), a copy of which is filed with the Commission. The following
summary outlines certain provisions of the Rights Agreement and is qualified
by reference to the full text of the form of the Rights Agreement.
 
  The Rights are attached to all Common Stock certificates representing shares
outstanding at the Record Date and shares issued between the Record Date and
the Distribution Date (as hereinafter defined), and no separate rights
certificates (the "Rights Certificates") have been distributed. The Rights
will separate from the Common Stock, separate Rights Certificates will be
issued and a distribution date (the "Distribution Date") will occur upon the
earlier to occur of (i) ten business days following the date of a public
announcement that there is an Acquiring Person (as defined below) (such date,
the "Stock Acquisition Date"), (ii) ten business days following commencement
of a tender or exchange offer that would result in the offeror beneficially
owning 15% or more of the Common Stock or (iii) ten business days after the
Board determines that the ownership of 10% or more of the Company's
outstanding Common Stock by a person is (A) intended to cause the Company to
repurchase the Common Stock beneficially owned by such person or (B) is
causing, or is reasonably likely to cause, a material adverse impact on the
Company.
 
  The term "Acquiring Person" means any person who, together with affiliates
and associates, acquires beneficial ownership of shares of Common Stock
representing 15% or more of the Common Stock, but shall not include the
Company, any subsidiary of the Company, any employee benefit plan of the
Company or of any Subsidiary of the Company, or any person or entity
organized, appointed or established by the Company for or pursuant to the
terms of such plan.
 
  In the event that a person becomes an Acquiring Person (except pursuant to
an offer for all outstanding shares of Common Stock which the independent
directors determine to be fair to and otherwise in the best interests of the
Company and its stockholders), each holder of a Right will thereafter have the
right to receive, upon exercise, Common Stock (or, in certain circumstances,
cash, property or other securities of the Company) having a calculated value
equal to two times the exercise price of the Right. Notwithstanding the
foregoing, following the occurrence of such event, all Rights that are, or
(under certain circumstances specified in the Rights Agreement) were,
beneficially owned by an Acquiring Person and certain related persons and
transferees will be null and void. However, Rights are not exercisable
following the occurrence of such event until such time as the Rights are no
longer redeemable as set forth below.
 
  The Rights expire on September 14, 2004, unless redeemed earlier by the
Board.
 
                                       9
<PAGE>
 
  At any time prior to the tenth day following the Stock Acquisition Date, the
Company may redeem the Rights, in whole, but not in part, at a price of $.01
per Right.
 
  Until a Right is exercised, the holder thereof, as such, will have no rights
as a stockholder of the Company, including without limitation, the right to
vote or to receive dividends.
 
  In general, the Rights Agreement may be amended by the Board (i) prior to
the Distribution Date in any manner, and (ii) on or after the Distribution
Date in certain respects including (a) to shorten or lengthen any time period
and (b) in a manner not adverse to the interests of Rights holders. However,
amendments extending the redemption period must be made while the Rights are
still redeemable.
 
  The Rights have certain anti-takeover effects and will cause substantial
dilution to a person or group that attempts to acquire the Company on terms
not approved by the Board. The Rights should not interfere with any merger or
other business combination approved by the Board, since the Board may redeem
the Rights as provided above.
 
SECTION 203 OF DELAWARE GENERAL CORPORATION LAW
 
  The Company is subject to the "business combination" statute of the Delaware
General Corporation Law (Section 203). In general, such statute prohibits a
publicly held Delaware corporation from engaging in a "business combination"
with any "interested stockholder" for a period of three years after the date
of the transaction in which the person became an "interested stockholder,"
unless (i) such transaction is approved by the board of directors prior to the
date the interested stockholder obtains such status, (ii) upon consummation of
such transaction, the "interested stockholder" beneficially owned at least 85%
of the voting stock of the corporation outstanding at the time the transaction
commenced, excluding for purposes of determining the number of shares
outstanding those shares owned by (a) persons who are directors and also
officers and (b) employee stock plans in which employee participants do not
have the right to determine confidentially whether shares held subject to the
plan will be tendered in a tender or exchange offer, or (iii) the "business
combination" is approved by the board of directors and authorized at an annual
or special meeting of stockholders by the affirmative vote of at least 66 2/3%
of the outstanding voting stock which is not owned by the "interested
stockholder." A "business combination" includes mergers, asset sales and other
transactions resulting in financial benefit to the "interested stockholder."
An "interested stockholder" is a person who, together with affiliates and
associates, owns (or within three years, did own) beneficially 15% or more of
a corporation's voting stock. The statute could prohibit or delay mergers or
other takeover or change in control attempts with respect to the Company and,
accordingly, may discourage attempts to acquire the Company.
 
CERTAIN EFFECTS OF AUTHORIZED BUT UNISSUED STOCK
 
  The Company's authorized but unissued shares of Common Stock and series
preferred stock may be issued without additional stockholder approval and may
be utilized for a variety of corporate purposes, including future offerings to
raise additional capital or to facilitate corporate acquisitions.
 
  The issuance of series preferred stock could have the effect of delaying or
preventing a change in control of the Company. The issuance of series
preferred stock could decrease the amount of earnings and assets available for
distribution to the holders of Common Stock or could adversely affect the
rights and powers, including voting rights, of the holders of the Common
Stock. In certain circumstances, such issuance could have the effect of
decreasing the market price of the Common Stock.
 
  One of the effects of the existence of unissued and unreserved Common Stock
or series preferred stock may be to enable the Board to issue shares to
persons friendly to current management which could render more difficult or
discourage an attempt to obtain control of the Company by means of a merger,
tender offer, proxy contest or otherwise, and thereby protect the continuity
of management. Such additional shares also could be used to dilute the stock
ownership of persons seeking to obtain control of the Company.
 
                                      10
<PAGE>
 
  The Company plans to issue additional shares of Common Stock (i) upon the
exercise of options which have been granted or which may be granted in the
future to directors, officers and employees of the Company and (ii) upon
conversion of the Trust Securities. The Company does not currently have any
plans to issue shares of series preferred stock, although, 10,000,000 shares
of Series A Preferred Stock have been designated pursuant to the Company's
Rights Plan.
 
LIMITATION OF DIRECTORS LIABILITY
 
  The Certificate contains a provision that limits the liability of McKesson's
directors for monetary damages for breach of fiduciary duty as a director to
the fullest extent permitted by the Delaware General Corporation Law. Such
limitation does not, however, affect the liability of a director (i) for any
breach of the director's duty of loyalty to the Company or its stockholders,
(ii) for acts or omissions not in good faith or that involve intentional
misconduct or a knowing violation of law, (iii) in respect of certain unlawful
dividend payments or stock redemptions or purchases and (iv) for any
transaction from which the director derives an improper personal benefit. The
effect of this provision is to eliminate the rights of the Company and its
stockholders (through stockholders' derivative suits on behalf of the Company)
to recover monetary damages against a director for breach of the fiduciary
duty of care as a director (including breaches resulting from negligent or
grossly negligent behavior) except in the situations described in clauses (i)
through (iv) above. This provision does not limit or eliminate the rights of
the Company or any stockholder to seek non-monetary relief such as an
injunction or rescission in the event of a breach of a director's duty of
care. In addition, the directors and officers of the Company have
indemnification protection.
 
                             PLAN OF DISTRIBUTION
 
  The Selling Stockholders or their respective distributees, pledgees, donees,
transferees or other successors in interest may offer Shares from time to time
depending on market conditions and other factors, in one or more transactions
on the NYSE, PE or other national securities exchanges on which the Shares are
traded, in the over-the-counter market or otherwise, at market prices
prevailing at the time of sale, at negotiated prices or at fixed prices. The
Shares may be offered in any manner permitted by law, including through
underwriters, brokers, dealers or agents, and directly to one or more
purchasers. Sales of Shares may involve (i) sales to underwriters who will
acquire Shares for their own account and resell them in one or more
transactions at fixed prices or at varying prices determined at time of sale,
(ii) block transactions in which the broker or dealer so engaged will attempt
to sell the Shares as agent but may position and resell a portion of the block
as principal to facilitate the transaction, (iii) purchases by a broker or
dealer as principal and resale by such broker or dealer for its account, (iv)
an exchange distribution in accordance with the rules of any such exchange,
and (v) ordinary brokerage transactions and transactions in which a broker
solicits purchasers. Brokers and dealers may receive compensation in the form
of underwriting discounts, concessions or commissions from the Selling
Stockholders and/or purchasers of Shares for whom they may act as agent (which
compensation may be in excess of customary commissions). The Selling
Stockholders and any broker or dealer that participates in the distribution of
Shares may be deemed to be underwriters and any commissions received by them
and any profit on the resale of Shares positioned by a broker or dealer may be
deemed to be underwriting discounts and commissions under the Securities Act.
In the event any Selling Stockholder engages an underwriter in connection with
the sale of the Shares, to the extent required, a Prospectus Supplement will
be distributed, which will set forth the number of Shares being offered and
the terms of the offering, including the names of the underwriters, any
discounts, commissions and other items constituting compensation to
underwriters, dealers or agents, the public offering price and any discounts,
commissions or concessions allowed or reallowed or paid by underwriters to
dealers.
 
  In addition, the Selling Stockholders may from time to time sell Shares in
transactions under Rule 144 promulgated under the Securities Act.
 
  Pursuant to the Registration Rights Agreement, dated as of January 28, 1997,
by and among the Company and the Selling Stockholders (the "Registration
Rights Agreement"), the Company will pay all registration
 
                                      11
<PAGE>
 
expenses in connection with all registrations of the Shares. The Selling
Stockholders and the Company have agreed to indemnify each other against
certain civil liabilities, including certain liabilities under the Securities
Act.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
  Article VIII of the By-Laws of the Company, in accordance with the
provisions of Section 145 of the General Corporation Law of Delaware (the
"Delaware Corporation Law"), provides that the Company shall indemnify any
person in connection with any threatened, pending or completed legal
proceeding (other than a legal proceeding by or in the right of the Company)
by reason of the fact that he is or was a director or officer of the Company
or is or was serving at the request of the Company as a director, officer,
employee or agent of another corporation, partnership or other enterprise
against expenses (including attorneys' fees), judgments, fines and amounts
paid in settlement actually and reasonably incurred in connection with such
legal proceeding if he acted in good faith and in a manner that he reasonably
believed to be in or not opposed to the best interests of the Company, and,
with respect to any criminal action or proceeding, if he had no reasonable
cause to believe that his conduct was unlawful. If the legal proceeding is by
or in the right of the Company, the director or officer may be indemnified by
the Company against expenses (including attorneys' fees) actually and
reasonably incurred in connection with the defense or settlement of such legal
proceeding if he acted in good faith and in a manner he reasonably believed to
be in or not opposed to the best interests of the Company, except that he may
not be indemnified in respect of any claim, issue or matter as to which he
shall have been adjudged to be liable to the Company unless a court determines
otherwise.
 
  Article VIII of McKesson's By-Laws allows the Company to maintain director
and officer liability insurance on behalf of any person who is or was a
director or officer of the Company or such person who serves or served as
director, officer, employee or agent of another corporation, partnership or
other enterprise at the request of the Company.
 
  Article VI of McKesson's Certificate, in accordance with Section 102(b)(7)
of the Delaware Corporation Law, provides that no director of the Company
shall be personally liable to the Company or its stockholders for monetary
damages for any breach of his fiduciary duty as a director; provided, however,
that such clause shall not apply to any liability of a director (1) for any
breach of his duty of loyalty to the Registrant or its stockholders, (2) for
acts or omissions that are not in good faith or involve intentional misconduct
or a knowing violation of the law, (3) under Section 174 of the Delaware
Corporation Law, or (4) for any transaction from which the director derived an
improper personal benefit.

ITEM 17. UNDERTAKINGS.
 
  (a) The undersigned hereby undertakes as follows:
 
    (1) To file, during any period in which offers or sales are being made, a
  post-effective amendment to this registration statement:
 
      (i) To include any prospectus required by Section 10(a)(3) of the
    Securities Act of 1933.
 
      (ii) To reflect in the prospectus any facts or events arising after
    the effective date of the registration statement (or the most recent
    post-effective amendment thereof) which, individually or in the
    aggregate, represent a fundamental change in the information set forth
    in this registration statement. Notwithstanding the foregoing, any
    increase or decrease in volume of securities offered (if the total
    dollar value of securities offered would not exceed that which was
    registered) and any deviation from the lower high end of the estimated
    maximum offering range may be reflected in the form of prospectus filed
    with the commission pursuant to Rule 424(b) if, in the aggregate, the
    changes in volume and price represent no more than a 20% change in the
    maximum aggregate offering price set forth in the "Calculation of
    Registration Fee" table in the effective registration statement.
 
      (iii) To include any material information with respect to the plan of
    distribution not previously disclosed in the registration statement or
    any material change to such information in the registration statement.
 
    (2) For the purpose of determining any liability under the Securities Act
  of 1933, each such post-effective amendment shall be deemed to be a new
  registration statement relating to the securities offered therein, and the
  offering of such securities at that time shall be deemed to be the initial
  bona fide offering thereof.
 
    (3) To remove from registration by means of a post-effective amendment
  any of the securities being registered which remain unsold at the
  termination of the offering.
 
 
                                     II-2
<PAGE>
 
  (b) The undersigned Registrant hereby undertakes that for purposes of
determining any liability under the Securities Act of 1933, each filing of the
Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to Section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in the
registration statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such
securities at that time shall be deemed to be the initial bona fide offering
thereof.
 
  (c) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the Registrant pursuant to the foregoing provisions, or otherwise, the
Registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the
Securities Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the Securities being registered, the Registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act and will be governed by the final adjudication of such issue.

                             A DELAWARE CORPORATION




                                   ARTICLE I

SECTION 2.  OTHER OFFICES.   The Corporation shall also have and maintain an

determine or the business of the Corporation may require.


                                   ARTICLE II

                             STOCKHOLDERS' MEETINGS


SECTION 1.  PLACE OF MEETINGS.   Meetings of the stockholders of the Corporation
shall be held at such place, either within or without the State of Delaware, as
may be designated from time to time by the Board of Directors, or, if not so
designated, then at the office of the Corporation required to be maintained
pursuant to Section 2 of ARTICLE I hereof.

SECTION 2.  ANNUAL MEETINGS.   The annual meetings of stockholders of the
Corporation for the purpose of election of directors and for such other business
as may lawfully come before it, shall be held on such date and at such time as
may be designated from time to time by the Board of Directors, or, if not so
designated, then at 10:00 a.m. on the last Wednesday in July in each year if not
a legal holiday, and, if a legal holiday, at the same hour and place on the next
succeeding day not a holiday.

SECTION 3.  SPECIAL MEETINGS.   Special Meetings of the stockholders of the
Corporation may be called, for any purpose or purposes, by the Chairman of the
Board or the President or the Board of Directors at any time.  Stockholders may
not call Special Meetings of the stockholders of the Corporation.

                                       1
<PAGE>
 
SECTION 4.  NOTICE OF MEETINGS.

(a) Except as otherwise provided by law or the Certificate of Incorporation,
written notice of each meeting of stockholders, specifying the place, date and
hour and purpose or purposes of the meeting, shall be given not less than 10 nor
more than 60 days before the date of the meeting to each stockholder entitled to
vote thereat, directed to his address as it appears upon the books of the
Corporation; except that where the matter to be acted on is a merger or
consolidation of the Corporation or a sale, lease or exchange of all or
substantially all of its assets, such notice shall be given not less than 20 nor
more than 60 days prior to such meeting.

(b) If at any meeting action is proposed to be taken which, if taken, would
entitle stockholders fulfilling the requirements of Section 262(d) of the
Delaware General Corporation Law to an appraisal of the fair value of their
shares, the notice of such meeting shall contain a statement of that purpose and
to that effect and shall be accompanied by a copy of that statutory section.

(c) When a meeting is adjourned to another time or place, notice need not be
given of the adjourned meeting if the time and place thereof are announced at
the meeting at which the adjournment is taken unless the adjournment is for more
than thirty days, or unless after the adjournment a new record date is fixed for
the adjourned meeting, in which event a notice of the adjourned meeting shall be
given to each stockholder of record entitled to vote at the meeting.

(d) Notice of the time, place and purpose of any meeting of stockholders may be
waived in writing, either before or after such meeting, and to the extent
permitted by law, will be waived by any stockholder by his attendance thereat,
in person or by proxy. Any stockholder so waiving notice of such meeting shall
be bound by the proceedings of any such meeting in all respects as if due notice
thereof had been given.

(e) Unless and until voted, every proxy shall be revocable at the pleasure of
the person who executed it or of his legal representatives or assigns, except in
those cases where an irrevocable proxy permitted by statute has been given.


SECTION 5.  QUORUM.   At all meetings of stockholders, except where otherwise
provided by law, the Certificate of Incorporation, or these By-Laws, the
presence, in person or by proxy duly authorized, of the holders of a majority of
the outstanding shares of stock entitled to vote shall constitute a quorum for
the transaction of business.  Shares, the voting of which at said meeting has
been enjoined, or which for any reason cannot be lawfully voted at such meeting,
shall not be counted to determine a quorum at said meeting.

In the absence of a quorum any meeting of stockholders may be adjourned, from
time to time, by vote of the holders of a majority of the shares represented
thereat, but no other business shall be transacted at such meeting.  At such
adjourned meeting at which a quorum is present or represented any business may
be transacted which might have been transacted at the original meeting.  The
stockholders present at a duly called or convened meeting, at which a quorum is
present, may continue to transact business until adjournment, notwithstanding
the withdrawal of enough stockholders to leave less than a quorum.  Except as
otherwise provided by law, the Certificate of Incorporation or these By-Laws,
all action taken by the holders of a majority of the voting power represented at
any meeting at which a quorum is present shall be valid and binding upon the
Corporation.

In the event that at any meeting at which the holders of more than one class or
series of the Corporation's capital stock are entitled to vote as a class, a
quorum of any such class or series is lacking, the holders of any class or
series represented by a quorum may proceed with the

                                       2
<PAGE>
 
transaction of the business to be transacted by that class or series, and if
such business is the election of directors, the director whose successors shall
not have been elected shall continue in office until their successors shall have
been duly elected and shall have qualified.


SECTION 6.  VOTING RIGHTS.

(a) Except as otherwise provided by law, only persons in whose names shares
entitled to vote stand on the stock records of the Corporation on the record
date for determining the stockholders entitled to vote at said meeting shall be
entitled to vote at such meeting. Shares standing in the names of two or more
persons shall be voted or represented in accordance with the determination of
the majority of such persons, or, if only one of such persons is present in
person or represented by proxy, such person shall have the right to vote such
shares and such shares shall be deemed to be represented for the purpose of
determining a quorum.

(b) Every person entitled to vote or execute consents shall have the right to do
so either in person or by an agent or agents authorized by a written proxy
executed by such person or his duly authorized agent, which proxy shall be filed
with the Secretary of the Corporation at or before the meeting at which it is to
be used. Said proxy so appointed need not be a stockholder. No proxy shall be
voted on after three years from its date unless the proxy provides for a longer
period.

(c) Without limiting the manner in which a stockholder may authorize another
person or persons to act for him as proxy pursuant to subsection (b) of this
Section, the following shall constitute a valid means by which a stockholder may
grant such authority:

   (1) A stockholder may execute a writing authorizing another person or persons
   to act for him as proxy.  Execution may be accomplished by the stockholder or
   his authorized officer, director, employee or agent signing such writing or
   causing his or her signature to be affixed to such writing by any reasonable
   means including, but not limited to, by facsimile signature.

   (2) A stockholder may authorize another person or persons to act for him as
   proxy by transmitting or authorizing the transmission of a telegram,
   cablegram, or other means of electronic transmission to the person who will
   be the holder of the proxy or to a proxy solicitation firm, proxy support
   service organization or like agent duly authorized by the person who will be
   the holder of the proxy to receive such transmission, provided that any such
   telegram, cablegram or other means of electronic transmission must either set
   forth or be submitted with information from which it can be determined that
   the telegram, cablegram or other electronic transmission was authorized by
   the stockholder.  If it is determined that such telegrams, cablegrams or
   other electronic transmissions are valid, the inspectors or, if there are no
   inspectors, such other persons making that determination shall specify the
   information upon which they relied.

(d) Any copy, facsimile telecommunication or other reliable reproduction of the
writing or transmission created pursuant to subsection (c) of this Section may
be substituted or used in lieu of the original writing or transmission for any
and all purposes for which the original writing or transmission could be used,
provided that such copy, facsimile telecommunication or other reproduction shall
be a complete reproduction of the entire original writing or transmission.


SECTION 7.  VOTING PROCEDURES AND INSPECTORS OF ELECTIONS.

(a) The Corporation shall, in advance of any meeting of stockholders, appoint
one or more inspectors to act at the meeting and make a written report thereof.
The Corporation may designate one or more persons as alternate inspectors to
replace any inspector who fails to act. If no

                                       3
<PAGE>
 
inspector or alternate is able to act at a meeting of stockholders, the person
presiding at the meeting shall appoint one or more inspectors to act at the
meeting. Each inspector, before entering upon the discharge of his duties, shall
take and sign an oath faithfully to execute the duties of inspector with strict
impartiality and according to the best of his ability.

(b) The inspectors shall (i) ascertain the number of shares outstanding and the
voting power of each, (ii) determine the shares represented at a meeting and the
validity of proxies and ballots, (iii) count all votes and ballots, (iv)
determine and retain for a reasonable period a record of the disposition of any
challenges made to any determination by the inspectors, and (v) certify their
determination of the number of shares represented at the meeting, and their
count of all votes and ballots. The inspectors may appoint or retain other
persons or entities to assist the inspectors in the performance of the duties of
the inspectors.

(c) The date and time of the opening and the closing of the polls for each
matter upon which the stockholders will vote at a meeting shall be announced at
the meeting. No ballot, proxies or votes, nor any revocations thereof or changes
thereto, shall be accepted by the inspectors after the closing of the polls
unless the Court of Chancery upon application by a stockholder shall determine
otherwise.

(d) In determining the validity and counting of proxies and ballots, the
inspectors shall be limited to an examination of the proxies, any envelopes
submitted with those proxies, any information provided in accordance with
Section 212(c)(2) of the Delaware General Corporation Law, ballots and the
regular books and records of the Corporation, except that the inspectors may
consider other reliable information for the limited purpose of reconciling
proxies and ballots submitted by or on behalf of banks, brokers, their nominees
or similar persons which represent more votes than the holder of a proxy is
authorized by the record owner to cast or more votes than the stockholder holds
of record. If the inspectors consider other reliable information for the limited
purpose permitted herein, the inspectors at the time they make their
certification pursuant to subsection (b)(v) of this Section shall specify the
precise information considered by them including the person or persons from whom
they obtained the information, when the information was obtained, the means by
which the information was obtained and the basis for the inspectors' belief that
such information is accurate and reliable.

(e) The provisions of this Section 7 shall not apply to any annual meeting of
stockholders held prior to the annual meeting of stockholders to be held in
1995.


SECTION 8.  LIST OF STOCKHOLDERS.  The officer who has charge of the stock
ledger of the Corporation shall prepare and make, at least 10 days before every
meeting of stockholders, a complete list of the stockholders entitled to vote at
said meeting, arranged in alphabetical order, showing the address of and the
number of shares registered in the name of each stockholder.  Such list shall be
open to the examination of any stockholder, for any purpose germane to the
meeting, during ordinary business hours, for a period of at least 10 days prior
to the meeting, either at a place within the city where the meeting is to be
held and which place shall be specified in the notice of the meeting, or, if not
specified, at the place where said meeting is to be held, and the list shall be
produced and kept at the time and place of meeting during the whole time
thereof, and may be inspected by any stockholder who is present.


SECTION 9.  STOCKHOLDER PROPOSALS AT ANNUAL MEETINGS.   At an annual meeting of
the stockholders, only such business shall be conducted as shall have been
properly brought before the meeting.  To be properly brought before an annual
meeting, business must be specified in the notice of meeting (or any supplement
thereto) given by or at the direction of the Board of Directors, otherwise
properly brought before the meeting by or at the direction of the Board of
Directors or

                                       4
<PAGE>
 
otherwise properly brought before the meeting by a stockholder.  In addition to
any other applicable requirements, for business to be properly brought before an
annual meeting by a stockholder, the stockholder must have given timely notice
thereof in writing to the Secretary of the Corporation.  To be timely, a
stockholder's notice must be delivered to or mailed and received at the
principal executive offices of the Corporation, not less than 60 days nor more
than 90 days prior to the meeting; provided, however, that in the event that
less than 70 days' notice or prior public disclosure of the date of the meeting
is given or made to stockholders, notice by the stockholder to be timely must be
so received not later than the close of business on the 10th day following the
day on which such notice of the date of the annual meeting was mailed or such
public disclosure was made.  A stockholder's notice to the Secretary shall set
forth as to each matter the stockholder proposes to bring before the annual
meeting, (i) a brief description of the business desired to be brought before
the annual meeting and the reasons for conducting such business at the annual
meeting, (ii) the name and record address of the stockholder proposing such
business, (iii) the class or series and number of shares of capital stock of the
Corporation which are owned beneficially or of record by the stockholder, (iv) a
description of all arrangements or understandings between the stockholder and
any other person or persons (including their names) in connection with the
proposal of such business by the stockholder and any material interest of the
stockholder in such business, and (v) a representation that the stockholder
intends to appear in person or by proxy at the annual meeting to bring such
business before the meeting.

Notwithstanding anything in the By-Laws to the contrary, no business shall be
conducted at the annual meeting except in accordance with the procedures set
forth in this Section 9, provided, however, that nothing in this Section 9 shall
be deemed to preclude discussion by any stockholder of any business properly
brought before the annual meeting in accordance with said procedure.

The Chairman of an annual meeting shall, if the facts warrant, determine and
declare to the meeting that business was not properly brought before the meeting
in accordance with the provisions of this Section 9, and if he should so
determine, he shall so declare to the meeting and any such business not properly
brought before the meeting shall not be transacted.


SECTION 10.  NOMINATIONS OF PERSONS FOR ELECTION TO THE BOARD OF DIRECTORS.   In
addition to any other applicable requirements, only persons who are nominated in
accordance with the following procedures shall be eligible for election as
directors.  Nominations of persons for election to the Board of Directors of the
Corporation may be made at a meeting of stockholders by or at the direction of
the Board of Directors, by any nominating committee or person appointed by the
Board of Directors or by any stockholder of the Corporation entitled to vote for
the election of directors at the meeting who complies with the notice procedures
set forth in this Section 10.  Such nominations, other than those made by or at
the direction of the Board of Directors, shall be made pursuant to timely notice
in writing to the Secretary of the Corporation.  To be timely, a stockholder's
notice shall be delivered to or mailed and received at the principal executive
offices of the Corporation not less than 60 days nor more than 90 days prior to
the meeting; provided, however, that in the event that less than 70 days' notice
or prior public disclosure of the date of the meeting is given or made to
stockholders, notice by the stockholder to be timely must be so received not
later than the close of business on the 10th day following the day on which such
notice of the date of the meeting was mailed or such public disclosure was made.
Such stockholder's notice shall set forth (a) as to each person whom the
stockholder proposes to nominate for election or re-election as a director, (i)
the name, age, business address and residence address of the person, (ii) the
principal occupation or employment of the person, (iii) the class and number of
shares of the Corporation which are beneficially owned by the person and (iv)
any other information relating to the person that is required to be disclosed in
solicitations for proxies for election of directors pursuant to Section 14 of
the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and the
rules and regulations promulgated thereunder; and (b) as to the stockholder
giving the notice, (i) the name and record address of the stockholder, (ii) the
class or

                                       5
<PAGE>
 
series and number of shares of capital stock of the Corporation which are owned
beneficially or of record by the stockholder, (iii) a description of all
arrangements or understandings between the stockholder and each proposed nominee
and any other person or persons (including their names) pursuant to which the
nomination(s) are to be made by the stockholder, (iv) a representation that such
stockholder intends to appear in person or by proxy at the meeting to nominate
the persons named in such notice and (v) any other information relating to the
stockholder that would be required to be disclosed in a proxy statement or other
filings required to be made in connection with solicitations of proxies for the
election of directors pursuant to Section 14 of the Exchange Act and the rules
and regulations promulgated thereunder.  Such notice must be accompanied by a
written consent of each proposed nominee being named as a nominee and to serve
as a director if elected.  The Corporation may require any proposed nominee to
furnish such other information as may reasonably be required by the Corporation
to determine the eligibility of such proposed nominee to serve as a director of
the Corporation.  No person shall be eligible for election as a director of the
Corporation unless nominated in accordance with the procedures set forth herein.
These provisions shall not apply to nomination of any persons entitled to be
separately elected by holders of preferred stock.

The Chairman of the meeting shall, if the facts warrant, determine and declare
to the meeting that a nomination was not made in accordance with the foregoing
procedure, and if he should so determine, he shall so declare to the meeting and
the defective nomination shall be disregarded.


                                  ARTICLE III

                                   DIRECTORS


SECTION 1.  GENERAL POWERS.   The property, affairs and business of the
Corporation shall be managed under the direction of its Board of Directors,
which may exercise all of the powers of the Corporation, except such as are by
law or by the Certificate of Incorporation or by these By-Laws expressly
conferred upon or reserved to the stockholders.


SECTION 2.  NUMBER AND TERM OF OFFICE; REMOVAL.   The number of directors of the
Corporation shall be fixed from time to time by these By-Laws but in no event
shall be less than three (3).  Until these By-Laws are further amended, the
number of directors shall be nine.  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 initial 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 these By-Laws 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 such alteration, amendment or repeal has been approved by either
the holders of all shares of stock entitled to vote

                                       6
<PAGE>
 
thereon or by a vote of a majority of the entire Board of Directors. The
provisions of this Section 2 shall not apply to directors governed by Section 15
of this ARTICLE III.


SECTION 3.  ELECTION OF DIRECTORS.  At each meeting of the stockholders for the
election of directors, the directors to be elected at such meeting shall be
elected by a plurality of votes given at such election.


SECTION 4.  VACANCIES.   Any vacancy occurring in the Board of Directors for any
cause other than by reason of an increase in the number of directors may be
filled by a majority of the remaining members of the Board of Directors,
although such majority is less than a quorum, or by the stockholders.  Any
vacancy occurring by reason of an increase in the number of directors may be
filled by action of a majority of the entire Board of Directors or by the
stockholders.  A director elected by the Board of Directors to fill a vacancy
shall be elected to hold office until the expiration of the term for which he
was elected and until his successor shall have been elected and shall have
qualified.  A director elected by the stockholders to fill a vacancy shall be
elected to hold office until the expiration of the term for which he was elected
and until his successor shall have been elected and shall have qualified.  The
provisions of this Section 4 shall not apply to directors governed by Section 15
of this ARTICLE III.


SECTION 5.  RESIGNATIONS.   A director may resign at any time by giving written
notice to the Board of Directors or to the Secretary.  Such resignation shall
take effect at the time specified therein and, unless otherwise specified
therein, the acceptance of such resignation shall not be necessary to make it
effective.


SECTION 6.  ANNUAL MEETINGS.   The Board of Directors, as constituted following
the vote of stockholders at any meeting of the stockholders for the election of
directors, may hold its first meeting for the purpose of organization and the
transaction of business, if a quorum be present, immediately after such meeting
and at the same place, and notice of such meeting need not be given.  Such first
meeting may be held at any other time and place specified in a notice given as
hereinafter provided for special meetings of the Board of Directors or in a
consent and waiver of notice thereof signed by all the directors.


SECTION 7.  REGULAR MEETINGS.   Regular meetings of the Board of Directors may
be held without notice at such places and times as may be fixed from time to
time by resolution of the Board.


SECTION 8.  SPECIAL MEETINGS; NOTICE.   Special meetings of the Board of
Directors may be called at any time by the Chairman of the Board or the
President and shall be called by the Secretary upon the written request of any
three directors and each special meeting shall be held at such place and time as
shall be specified in the notice thereof.  At least twenty-four (24) hours'
notice of each such special meeting shall be given to each director personally
or sent to him addressed to his residence or usual place of business by
telephone, telegram or facsimile transmission, or at least 120 hours' notice of
each such special meeting shall be given to each director by letter sent to him
addressed as aforesaid or on such shorter notice and by such means as the person
or persons calling such meeting may deem reasonably necessary or appropriate in
light of the circumstances. Any notice by letter or telegram shall be deemed to
be given when deposited in the United States mail so addressed or when duly
deposited at an appropriate office for transmission by telegram, as the case may
be. Such notice need not state the business to be transacted at or the purpose
or purposes of such special meeting. No notice of any such special meeting of
the Board of Directors need be

                                       7
<PAGE>
 
given to any director who attends in person or who, in writing executed and
filed with the records of the meeting, either before or after the holding
thereof, waives such notice. No notice need be given of an adjourned meeting of
the Board of Directors.


SECTION 9.  QUORUM AND MANNER OF ACTING.   A majority of the total number of
directors, but in no event less than two directors, shall constitute a quorum
for the transaction of business at any annual, regular or special meeting of the
Board of Directors.  Except as otherwise provided by law, by the Certificate of
Incorporation or by these By-Laws, the act of a majority of the directors
present at any meeting, at which a quorum is present, shall be the act of the
Board of Directors.  In the absence of a quorum, a majority of the directors
present may adjourn the meeting from time to time until a quorum be had.


SECTION 10.  CONSENT IN WRITING.   Any action required or permitted to be taken
at any meeting of the Board of Directors or any committee thereof may be taken
without a meeting, if a written consent to such action is signed by all members
of the Board or of such committee, as the case may be, and such written consent
is filed with the minutes of proceedings of the Board or such committee.


SECTION 11.  COMMITTEES.

(a) Executive Committee. The Board of Directors may, by resolution passed by a
majority of a quorum of the Board, appoint an Executive Committee of not less
than three members, each of whom shall be a director. The Executive Committee,
to the extent permitted by law, shall have and may exercise when the Board of
Directors is not in session all powers of the Board in the management of the
business and affairs of the Corporation, including, without limitation, the
power and authority to declare a dividend or to authorize the issuance of stock,
except such Committee shall not have the power or authority (i) to approve,
adopt, or recommend to stockholders any action or matter required by the
Delaware General Corporation Law to be submitted for stockholder approval; or
(ii) to adopt, amend, or repeal any By-Law of the Corporation.

(b) Other Committees. The Board of Directors may, by resolution passed by a
majority of a quorum of the Board, from time to time appoint such other
committees as may be permitted by law. Such other committees appointed by the
Board of Directors shall have such powers and perform such duties as may be
prescribed by the resolution or resolutions creating such committee, but in no
event shall any such committee have the powers denied to the Executive Committee
in these By-Laws.

(c) Term. The members of all committees of the Board of Directors shall serve a
term coexistent with that of the Board of Directors which shall have appointed
such committee. The Board, subject to the provisions of subsections (a) or (b)
of this Section 11, may at any time increase or decrease the number of members
of a committee or terminate the existence of a committee; provided, that no
committee shall consist of less than one member. The membership of a committee
member shall terminate on the date of his death or voluntary resignation, but
the Board may at any time for any reason remove any individual committee member
and the Board may fill any committee vacancy created by death, resignation,
removal or increase in the number of members of the committee. The Board of
Directors may designate one or more directors as alternate members of any
committee, who may replace any absent or disqualified member at any meeting of
the committee, and, in addition, in the absence or disqualification of any
member of a committee, the member or members thereof present at any meeting and
not disqualified from voting, whether or not he or they constitute a quorum, may
unanimously appoint another member of the Board of Directors to act at the
meeting in the place of any such absent or disqualified member.

                                       8
<PAGE>
 
(d) Meetings. Unless the Board of Directors shall otherwise provide, regular
meetings of the Executive Committee or any other committee appointed pursuant to
this Section 11 shall be held at such times and places as are determined by the
Board of Directors, or by any such committee, and when notice thereof has been
given to each member of such committee, no further notice of such regular
meetings need be given thereafter; special meetings of any such committee may be
held at the principal office of the Corporation required to be maintained
pursuant to Section 2 of ARTICLE I hereof; or at any place which has been
designated from time to time by resolution of such committee or by written
consent of all members thereof, and may be called by any director who is a
member of such committee, upon written notice to the members of such committee
of the time and place of such special meeting given in the manner provided for
the giving of written notice to members of the Board of Directors of the time
and place of special meetings of the Board of Directors. Notice of any special
meeting of any committee may be waived in writing at any time after the meeting
and will be waived by any director by attendance thereat. A majority of the
authorized number of members of any such committee shall constitute a quorum for
the transaction of business, and the act of a majority of those present at any
meeting at which a quorum is present shall be the act of such committee.


SECTION 12.  TELEPHONE MEETINGS.   The Board of Directors or any committee
thereof may participate in a meeting by means of a conference telephone or
similar communications equipment if all members of the Board or of such
committee, as the case may be, participating in the meeting can hear each other
at the same time.  Participation in a meeting by these means shall constitute
presence in person at the meeting.


SECTION 13.  COMPENSATION.  The directors may be paid their expenses, if any, of
attendance at each meeting of the Board of Directors and may be paid a fixed sum
for attendance at each meeting of the Board of Directors and/or a stated salary
as director.  No such payment shall preclude any director from serving the
Corporation in any other capacity and receiving compensation therefor.   Members
of special or standing committees may be allowed like compensation for attending
committee meetings.


SECTION 14.  INTERESTED DIRECTORS.  No contract or transaction between the
Corporation and one or more of its directors or officers, or between the
Corporation and any other corporation, partnership, association, or other
organization in which one or more of its directors or officers are directors or
officers, or have a financial interest, shall be void or voidable solely for
this reason, or solely because the director or officer is present at or
participates in the meeting of the Board of Directors or committee thereof which
authorizes the contract or transaction, or solely because his or their votes are
counted for such purpose if (i) the material facts as to his or their
relationship or interest and as to the contract or transaction are disclosed or
are known to the Board of Directors or committee, and the Board of Directors or
committee in good faith authorizes the contract or transaction by the
affirmative votes of a majority of the disinterested directors, even though the
disinterested directors be less than a quorum; or (ii) the material facts as to
his or their relationship or interest and as to the contract or transaction are
disclosed or are known to the stockholders entitled to vote thereon, and the
contract or transaction is specifically approved in good faith by vote of the
stockholders; or (iii) the contract or transaction is fair as to the Corporation
as of the time it is authorized, approved or ratified, by the Board of
Directors, a committee thereof or the stockholders.  Common or interested
directors may be counted in determining the presence of a quorum at a meeting of
the Board of Directors or of a committee which authorizes the contract or
transaction.

SECTION 15.  DIRECTORS ELECTED BY SPECIAL CLASS OR SERIES.   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 referred to in Section 2 of this ARTICLE III.  Any directors so
elected shall be subject to removal in such manner as may be provided by law or
by the Certificate of Incorporation of this Corporation.  The provisions of
Sections 2 and 4 of this ARTICLE III do not apply to directors governed by this
Section 15.

                                       11
<PAGE>
 
appointed), or by the President or any Vice President and by the Treasurer or
Assistant Treasurer or the Secretary or Assistant Secretary, certifying the
number of shares owned by him in the Corporation. Any or all of the signatures
on the certificate may be a facsimile. In case any officer, transfer agent, or
registrar who has signed or whose facsimile signature has been placed upon a
certificate shall have ceased to be such officer, transfer agent, or registrar
before such certificate is issued, it may be issued with the same effect as if
he were such officer, transfer agent, or registrar at the date of issue. If the
Corporation shall be authorized to issue more than one class of stock or more
than one series of any class, the powers, designations, preferences and
relative, participating, optional or other special rights of each class of stock
or series thereof and the qualifications, limitations or restrictions of such
preferences and/or rights shall be set forth in full or summarized on the face
or back of the certificate which the Corporation shall issue to represent such
class or series of stock, provided that, except as otherwise provided in Section
202 of the General Corporation Law of Delaware, in lieu of the foregoing
requirements, there may be set forth on the face or back of the certificate
which the Corporation shall issue to represent such class or series of stock, a
statement that the Corporation will furnish without charge to each stockholder
who so requests the powers, designations, preferences and relative,
participating, optional or other special rights of each class of stock or series
thereof and the qualifications, limitations or restrictions of such preferences
and/or rights.


SECTION 2.  LOST CERTIFICATES.   The Board of Directors may direct a new
certificate or certificates to be issued in place of any certificate or
certificates theretofore issued by the Corporation alleged to have been lost or
destroyed, upon the making of an affidavit of that fact by the person claiming
the certificate of stock to be lost or destroyed.  When authorizing such issue
of a new certificate or certificates, the Board of Directors may, in its
discretion and as a condition precedent to the issuance thereof, require the
owner of such lost or destroyed certificate or certificates, or his legal
representative, to indemnify the Corporation in such manner as it shall require
and/or to give the Corporation a surety bond in such form and amount as it may
direct as indemnity against any claim that may be made against the Corporation
with respect to the certificate alleged to have been lost or destroyed.


SECTION 3.  TRANSFERS.   Transfers of record of shares of stock of the
Corporation shall be made only upon its books by the holders thereof, in person
or by attorney duly authorized, and upon the surrender of a certificate or
certificates for a like number of shares, properly endorsed.


SECTION 4.  FIXING RECORD DATES.   In order that the Corporation may determine
the stockholders entitled to notice of or to vote at any meeting of stockholders
or any adjournment thereof, or to express consent to corporate action in writing
without a meeting, or entitled to receive payment of any dividend or other
distribution or allotment of any rights, or entitled to exercise any rights in
respect of any change, conversion or exchange of stock or for the purpose of any
other lawful action, the Board of Directors may fix, in advance, a record date,
which shall not be more than 60 nor less than 10 days before the date of such
meeting, nor more than 60 days prior to any other action. If no record date is
fixed: (1) the record date for determining stockholders entitled to notice of or
to vote at a meeting of stockholders shall be at the close of business on the
day next preceding the day on which notice is given, or, if notice is waived, at
the close of business on the day next preceding the day on which the meeting is
held; (2) the record date for determining stockholders entitled to express
consent to corporate action in writing without a meeting, when no prior action
by the Board of Directors is necessary, shall be the day on which the first
written consent is expressed; (3) the record date for determining stockholders
for any other purpose shall be at the close of business on the day on which the
Board of Directors adopts the resolution relating thereto. A determination of
stockholders of record entitled to notice of or to vote at a

                                       12
<PAGE>
 
meeting of stockholders shall apply to any adjournment of the meeting; provided,
however, that the Board of Directors may fix a new record date for the adjourned
meeting.

SECTION 5.  REGISTERED STOCKHOLDERS.   The Corporation shall be entitled to
recognize the exclusive right of a person registered on its books as the owner
of shares to receive dividends, and to vote as such owner, and shall not be
bound to recognize any equitable or other claim to or interest in such share or
shares on the part of any other person, whether or not it shall have express or
other notice thereof, except as otherwise provided by the laws of Delaware.


SECTION 6.  REGULATIONS.   The Board of Directors may make such rules and
regulations as it may deem expedient concerning the issue, transfer and
registration of certificates for shares of the stock and other securities of the
Corporation, and may appoint transfer agents and registrars of any class of
stock or other securities of the Corporation.


SECTION 7.  OTHER SECURITIES OF THE CORPORATION.   All bonds, debentures and
other corporate securities of the Corporation, other than stock certificates,
may be signed by the Chairman of the Board (if there be such an officer
appointed), or the President or any Vice President or such other person as may
be authorized by the Board of Directors and the corporate seal impressed thereon
or a facsimile of such seal imprinted thereon and attested by the signature of
the Secretary or an Assistant Secretary, or the Treasurer or an Assistant
Treasurer; provided, however, that where any such bond, debenture or other
corporate security shall be authenticated by the manual signature of a trustee
under an indenture pursuant to which such bond, debenture or other corporate
security shall be issued, the signature of the persons signing and attesting the
corporate seal on such bond, debenture or other corporate security may be the
imprinted facsimile of the signatures of such persons.  Interest coupons
appertaining to any such bond, debenture or other corporate security,
authenticated by a trustee as aforesaid, shall be signed by the Treasurer or an
Assistant Treasurer of the Corporation, or such other person as may be
authorized by the Board of Directors, or bear imprinted thereon the facsimile
signature of such person.  In case any officer who shall have signed or attested
any bond, debenture or other corporate security or whose facsimile signature
shall appear thereon shall have ceased to be such officer before the bond,
debenture or other corporate security so signed or attested shall have been
delivered, such bond, debenture or other corporate security nevertheless may be
adopted by the Corporation and issued and delivered as though the person who
signed the same or whose facsimile signature shall have been used thereon had
not ceased to be such officer of the Corporation.


                                  ARTICLE VII

                                 CORPORATE SEAL


   The corporate seal shall consist of a die bearing the name of the Corporation
and the state and date of its incorporation.  Said seal may be used by causing
it or a facsimile thereof to be impressed or affixed or reproduced or otherwise.

                                  ARTICLE VIII

          INDEMNIFICATION OF OFFICERS, DIRECTORS, EMPLOYEES AND AGENTS

SECTION 1.  POWER TO INDEMNIFY IN ACTIONS, SUITS OR PROCEEDINGS OTHER THAN THOSE
BY OR IN THE RIGHT OF THE CORPORATION.   Subject to Section 3 of this ARTICLE
VIII, the Corporation shall indemnify any person who was or is a party or is
threatened to be made a party to any threatened, pending or completed action,
suit or proceeding, whether civil, criminal, administrative or investigative
(other than an action by or in the right of the Corporation) by reason of the
fact that he is or was a director or officer of the Corporation, or is or was a
director or officer of the Corporation serving at the request of the Corporation
as a director or officer, employee or agent of another corporation, partnership,
joint venture, trust, employee benefit plan or other enterprise, against
expenses (including attorneys' fees), judgments, fines and amounts paid in
settlement actually and reasonably incurred by him in connection with such
action, suit or proceeding if he acted in good faith and in a manner he
reasonably believed to be in or not opposed to the best interests of the
Corporation, and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful.   The termination of any
action, suit or proceeding by judgment, order, settlement, conviction, or upon a
plea of nolo contendere or its equivalent, shall not, of itself, create a
        ---- ----------                                                  
presumption that the person did not act in good faith and in a manner which he
reasonably believed to be in or not opposed to the best interests of the
Corporation, and, with respect to any criminal action or proceeding, had
reasonable cause to believe that his conduct was unlawful.  The right to
indemnification conferred in this ARTICLE VIII shall be a contract right.


SECTION 2.  POWER TO INDEMNIFY IN ACTIONS, SUITS OR PROCEEDINGS BY OR IN THE
RIGHT OF THE CORPORATION.  Subject to Section 3 of this ARTICLE VIII, the
Corporation shall indemnify any person who was or is a party or is threatened to
be made a party to any threatened, pending or completed action or suit by or in
the right of the Corporation to procure a judgment in its favor by reason of the
fact that he is or was a director or officer of the Corporation, or is or was a
director or officer of the Corporation serving at the request of the Corporation
as a director, officer, employee or agent of another corporation, partnership,
joint venture, trust, employee benefit plan or other enterprise against expenses
(including attorneys' fees) actually and reasonably incurred by him in
connection with the defense or settlement of such action or suit if he acted in
good faith and in a manner he reasonably believed to be in or not opposed to the
best interests of the Corporation; except that no indemnification shall be made
in respect of any claim, issue or matter as to which such person shall have been
adjudged to be liable to the Corporation unless and only to the extent that the
Court of Chancery or the court in which such action or suit was brought shall
determine upon application that, despite the adjudication of liability but in
view of all the circumstances of the case, such person is fairly and reasonably
entitled to indemnity for such expenses which the Court of Chancery or such
other court shall deem proper.


SECTION 3.  AUTHORIZATION OF INDEMNIFICATION.  Any indemnification under this
ARTICLE VIII (unless ordered by a court) shall be made by the Corporation only
as authorized in the specific case upon a determination that indemnification of
the director or officer is proper in the circumstances because he has met the
applicable standard of conduct set forth in Section 1 or Section 2 of this
ARTICLE VIII, as the case may be.  Such determination shall be made (i) by the
Board of Directors by a majority vote of a quorum consisting of directors who
were not parties to such action, suit or proceeding, or (ii) if such a quorum is
not obtainable, or, even if obtainable a quorum of disinterested directors so
directs, by independent legal counsel in a written opinion, or (iii) by the
stockholders.  To the extent, however, that a director or officer of the
Corporation has been successful on the merits or otherwise in defense of any
action, suit or proceeding described above, or in defense of any claim, issue or
matter therein, he shall be indemnified against expenses

                                       14
<PAGE>
 
(including attorneys' fees) actually and reasonably incurred by him in
connection therewith, without the necessity of authorization in the specific
case.


SECTION 4.  GOOD FAITH DEFINED.  For purposes of any determination under Section
3 of this ARTICLE VIII, a person shall be deemed to have acted in good faith and
in a manner he reasonably believed to be in or not opposed to the best interests
of the Corporation, or, with respect to any criminal action or proceeding, to
have had no reasonable cause to believe his conduct was unlawful, if his action
is based on the records or books of account of the Corporation or another
enterprise, or on information supplied to him by the officers of the Corporation
or another enterprise in the course of their duties, or on the advice of legal
counsel for the Corporation or another enterprise or on information or records
given or reports made to the Corporation or another enterprise by an independent
certified public accountant or by an appraiser or other expert selected with
reasonable care by the Corporation or another enterprise.  The term "another
enterprise" as used in this Section 4 shall mean any other corporation or any
partnership, joint venture, trust, employee benefit plan or other enterprise of
which such person is or was serving at the request of the Corporation as a
director, officer, employee or agent.  The provisions of this Section 4 shall
not be deemed to be exclusive or to limit in any way the circumstances in which
a person may be deemed to have met the applicable standard of conduct set forth
in Sections 1 or 2 of this ARTICLE VIII, as the case may be.


SECTION 5.  INDEMNIFICATION BY A COURT.  Notwithstanding any contrary
determination in the specific case under Section 3 of this ARTICLE VIII, and
notwithstanding the absence of any determination thereunder, any director or
officer may apply to any court of competent jurisdiction in the State of
Delaware for indemnification to the extent otherwise permissible under Sections
1 and 2 of this ARTICLE VIII.  The basis of such indemnification by a court
shall be a determination by such court that indemnification of the director or
officer is proper in the circumstances because he has met the applicable
standards of conduct set forth in Sections 1 or 2 of this ARTICLE VIII, as the
case may be.  Neither a contrary determination in the specific case under
Section 3 of this ARTICLE VIII nor the absence of any determination thereunder
shall be a defense to such application or create a presumption that the director
or officer seeking indemnification has not met any applicable standard of
conduct.  Notice of any application for indemnification pursuant to this Section
5 shall be given to the Corporation promptly upon the filing of such
application.   If successful, in whole or in part, the director or officer
seeking indemnification shall also be entitled to be paid the expense of
prosecuting such application.


SECTION 6.  EXPENSES PAYABLE IN ADVANCE.  Expenses incurred by a director or
officer in defending or investigating a threatened or pending action, suit or
proceeding shall be paid by the Corporation in advance of the final disposition
of such action, suit or proceeding upon receipt of an undertaking by or on
behalf of such director or officer to repay such amount if it shall ultimately
be determined that he is not entitled to be indemnified by the Corporation as
authorized in this ARTICLE VIII.


SECTION 7.  NONEXCLUSIVITY OF INDEMNIFICATION AND ADVANCEMENT OF EXPENSES.  The
indemnification and advancement of expenses provided by or granted pursuant to
this ARTICLE VIII shall not be deemed exclusive of any other rights to which
those seeking indemnification or advancement of expenses may be entitled under
any By-Law, agreement, contract, vote of stockholders or disinterested directors
or pursuant to the direction (howsoever embodied) of any court of competent
jurisdiction or otherwise, both as to action in his official capacity and as to
action in another capacity while holding such office, it being the policy of the
Corporation that indemnification of the persons specified in Sections 1 and 2 of
this ARTICLE VIII shall be made to

                                       15
<PAGE>
 
the fullest extent permitted by law.  The provisions of this ARTICLE VIII shall
not be deemed to preclude the indemnification of any person who is not specified
in Sections 1 or 2 of this ARTICLE VIII but whom the Corporation has the power
or obligation to indemnify under the provisions of the General Corporation Law
of the State of Delaware, or otherwise.


SECTION 8.  INSURANCE.  The Corporation may purchase and maintain insurance on
behalf of any person who is or was a director or officer of the Corporation, or
is or was a director or officer of the Corporation serving at the request of the
Corporation as a director, officer, employee or agent of another corporation,
partnership, joint venture, trust, employee benefit plan or other enterprise
against any liability asserted against him and incurred by him in any such
capacity, or arising out of his status as such, whether or not the Corporation
would have the power or the obligation to indemnify him against such liability
under the provisions of this ARTICLE VIII.


SECTION 9.  CERTAIN DEFINITIONS.  For purposes of this ARTICLE VIII, references
to "the Corporation" shall include, in addition to the resulting corporation,
any constituent corporation (including any constituent of a constituent)
absorbed in a consolidation or merger which, if its separate existence had
continued, would have had power and authority to indemnify its directors or
officers, so that any person who is or was a director or officer of such
constituent corporation, or is or was a director or officer of such constituent
corporation serving at the request of such constituent corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust, employee benefit plan or other enterprise, shall stand in the
same position under the provisions of this ARTICLE VIII with respect to the
resulting or surviving corporation as he would have with respect to such
constituent corporation if its separate existence had continued.  For purposes
of this ARTICLE VIII, references to "fines" shall include any excise taxes
assessed on a person with respect to an employee benefit plan; and references to
"serving at the request of the Corporation" shall include any service as a
director, officer, employee or agent of the Corporation which imposes duties on,
or involves services by, such director or officer with respect to an employee
benefit plan, its participants or beneficiaries; and a person who acted in good
faith and in a manner he reasonably believed to be in the interest of the
participants and beneficiaries of an employee benefit plan shall be deemed to
have acted in a manner "not opposed to the best interests of the Corporation" as
referred to in this ARTICLE VIII.


SECTION 10.  SURVIVAL OF INDEMNIFICATION AND ADVANCEMENT OF EXPENSES.  The
indemnification and advancement of expenses provided by, or granted pursuant to,
this ARTICLE VIII shall, unless otherwise provided when authorized or ratified,
continue as to a person who has ceased to be a director or officer and shall
inure to the benefit of the heirs, executors and administrators of such a
person.


SECTION 11.  LIMITATION ON INDEMNIFICATION.  Notwithstanding anything contained
in this ARTICLE VIII to the contrary, except for proceedings to enforce rights
to indemnification (which shall be governed by Section 5 hereof), the
Corporation shall not be obligated to indemnify any director or officer in
connection with a proceeding (or part thereof) initiated by such person unless
such proceeding (or part thereof) was authorized or consented to by the Board of
Directors of the Corporation.


SECTION 12.  INDEMNIFICATION OF EMPLOYEES AND AGENTS.  The Corporation may, to
the extent authorized from time to time by the Board of Directors, provide
rights to indemnification and to the advancement of expenses to employees and
agents of the Corporation similar to those conferred in this ARTICLE VIII to
directors and officers of the Corporation.

                                       16
<PAGE>
 
SECTION 13.  EFFECT OF AMENDMENT.   Any amendment, repeal or modification of
this ARTICLE VIII shall not (a) adversely affect any right or protection of any
director or officer existing at the time of such amendment, repeal or
modification, or (b) apply to the indemnification of any such person for
liability, expense, or loss stemming from actions or omissions occurring prior
to such amendment, repeal, or modification.


SECTION 14.  AUTHORITY TO ENTER INTO INDEMNIFICATION AGREEMENTS.   The
Corporation may enter into indemnification agreements with the directors and
officers of the Corporation, including, without limitation, any indemnification
agreement in substantially the form set forth in Exhibit 1 attached to these By-
Laws.


                                   ARTICLE IX

                                    NOTICES

Whenever, under any provisions of these By-Laws, notice is required to be given
to any stockholder, the same shall be given in writing, timely and duly
deposited in the United States Mail, postage prepaid, and addressed to his last
known post office address as shown by the stock record of the Corporation or its
transfer agent.  Any notice required to be given to any director may be given by
any of the methods stated in Section 8 of ARTICLE III hereof, except that such
notice other than one which is delivered personally, shall be sent to such
address or (in the case of facsimile telecommunication) facsimile telephone
number as such director shall have disclosed in writing to the Secretary of the
Corporation, or, in the absence of such filing, to the last known post office
address of such director.  If no address of a stockholder or director be known,
such notice may be sent to the office of the Corporation required to be
maintained pursuant to Section 2 of ARTICLE I hereof.  An affidavit of mailing,
executed by a duly authorized and competent employee of the Corporation or its
transfer agent appointed with respect to the class of stock affected, specifying
the name and address or the names and addresses of the stockholder or
stockholders, director or directors, to whom any such notice or notices was or
were given, and the time and method of giving the same, shall be conclusive
evidence of the statements therein contained.  All notices given by mail, as
above provided, shall be deemed to have been given as at the time of mailing and
all notices given by telegram or other means of electronic transmission shall be
deemed to have been given as at the sending time recorded by the telegraph
company or other electronic transmission equipment operator transmitting the
same.  It shall not be necessary that the same method of giving be employed in
respect of all directors, but one permissible method may be employed in respect
of any one or more, and any other permissible method or methods may be employed
in respect of any other or others.  The period or limitation of time within
which any stockholder may exercise any option or right, or enjoy any privilege
or benefit, or be required to act, or within which any director may exercise any
power or right, or enjoy any privilege, pursuant to any notice sent him in the
manner above provided, shall not be affected or extended in any manner by the
failure of such a stockholder or such director to receive such notice.  Whenever
any notice is required to be given under the provisions of this statutes or of
the Certificate of Incorporation, or of these By-Laws, a waiver thereof in
writing signed by the person or persons entitled to said notice, whether before
or after the time stated therein, shall be deemed equivalent thereto.  Whenever
notice is required to be given, under any provision of law or of the Certificate
of Incorporation or By-Laws of the Corporation, to any person with whom
communication is unlawful, the giving of such notice to such person shall not be
required and there shall be no duty to apply to any governmental authority or
agency for a license or permit to give such notice to such person.  Any action
or meeting which shall be taken or held without notice to any such person with
whom communication is unlawful shall have the same force and effect as if such
notice had been duly given.  In the event that the action taken by the
Corporation is such as to require the filing of a certificate under any
provision of the Delaware General Corporation Law, the certificate shall state, 

                                       17
<PAGE>
 
if such is the fact and if notice is required, that notice was given to all
persons entitled to receive notice except such persons with whom communication
is unlawful.


                                   ARTICLE X

                                   AMENDMENTS

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 ARTICLE V of the Certificate of Incorporation of the
Corporation 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.

                           INDEMNIFICATION AGREEMENT


AGREEMENT, effective as of ______, 19__, between McKesson Corporation, a
Delaware corporation (the "Company"), and ______________ (the "Indemnitee").

WHEREAS, it is essential to the Company to retain and attract as directors and
officers the most capable persons available.

WHEREAS, Indemnitee is a director/officer of the Company;

WHEREAS, both the Company and Indemnitee recognize the increased risk of
litigation and other claims being asserted against directors of public companies
in today's environment;

WHEREAS, the Certificate of Incorporation and the By-laws of the Company require
the Company to indemnify and advance expenses to its directors to the fullest
extent permitted by law and the Indemnitee has been serving and continues to
serve as a director or officer of the Company in part in reliance on such
Certificate of Incorporation and By-laws;

WHEREAS, in recognition of Indemnitee's need for substantial protection against
personal liability in order to enhance Indemnitee's continued service to the
Company in an effective manner and Indemnitee's reliance on the aforesaid
Certificate of Incorporation and By-laws, and in part to provide Indemnitee with
specific contractual assurance that the protection promised by such Certificate
of Incorporation and By-laws will be available to Indemnitee (regardless of,
among other things, any amendment to or revocation of such Certificate of
Incorporation and By-laws or any change in the composition of the Company's
Board of Directors or acquisition transaction relating to the Company), and in
order to induce Indemnitee to continue to provide services to the Company as a
director or officer thereof, the Company wishes to provide in this Agreement for
the indemnification of and the advancing of expenses to Indemnitee to the
fullest extent (whether partial or complete) permitted by law and as set forth
in this Agreement, and, to the extent insurance is maintained, for the continued
coverage of Indemnitee under the Company's directors' and officers' liability
insurance policies.

NOW, THEREFORE, in consideration of the premises and of Indemnitee continuing to
serve the Company directly or, at its request, with another enterprise, and
intending to be legally bound hereby, the parties hereto agree as follows:


1. CERTAIN DEFINITIONS.

   (a) Change in Control: shall be deemed to have occurred if (i) any "person"
(as such term is used in Sections 13(d) and 14(d) of the Securities Exchange Act
of 1934, as amended), other than a trustee or other fiduciary holding securities
under an employee benefit plan of the Company or a corporation owned directly or
indirectly by the stockholders of the Company in substantially the same
proportions as their ownership of stock of the Company, is or becomes the
"beneficial owner" (as defined in Rule 13d-3 under said Act), directly or
indirectly, of securities of the Company representing 20% or more of the total
voting power represented by the Company's then outstanding Voting Securities, or
(ii) during any period of two consecutive years, individuals who at the
beginning of such period constitute the Board of Directors of the Company and
any new director whose election by the Board of Directors or nomination for
election by the Company's stockholders was approved by a vote of at least two-
thirds (2/3) of the directors then still in office who either

                                       1
<PAGE>
 
were directors at the beginning of the period or whose election or nomination
for election was previously so approved, cease for any reason to constitute a
majority thereof, or (iii) the stockholders of the Company approve a merger or
consolidation of the Company with any other corporation, other than a merger or
consolidation which would result in the Voting Securities of the Company
outstanding immediately prior thereto continuing to represent (either by
remaining outstanding or by being converted into Voting Securities of the
surviving entity) at least 80% of the total voting power represented by the
Voting Securities of the Company or such surviving entity outstanding
immediately after such merger or consolidation, or the stockholders of the
Company approve a plan of complete liquidation of the Company or an agreement
for the sale or disposition by the Company (in one transaction or a series of
transactions) of all or substantially all of the Company's assets.

   (b) Expense:  include attorneys' fees and all other costs, expenses and
obligations paid or incurred in connection with investigating, defending, being
a witness in or participating in (including on appeal), or preparing to defend,
be a witness in or participate in any Proceeding relating to any Indemnifiable
Event.

   (c) Indemnifiable Event:  any event or occurrence that takes place either
prior to or after the execution of this Agreement, related to the fact that
Indemnitee is or was a director or an officer of the Company, or while a
director or officer is or was serving at the request of the Company as a
director, officer, employee, trustee, agent or fiduciary of another corporation,
partnership, joint venture, employee benefit plan, trust or other enterprise, or
by reason of anything done or not done by Indemnitee in any such capacity.

   (d) Potential Change in Control:  shall be deemed to have occurred if (i) the
Company enters into an agreement or arrangement, the consummation of which would
result in the occurrence of Change in Control; (ii) any person (including the
Company) publicly announces an intention to take or to consider taking actions
which if consummated would constitute Change in Control; (iii) any person, other
than a trustee or other fiduciary holding securities under an employee benefit
plan of the Company acting in such capacity or a corporation owned, directly or
indirectly, by the stockholders of the Company in substantially the same
proportions as their ownership of stock of the Company, who is or becomes the
beneficial owner, directly or indirectly, of securities of the Company
representing 10% or more of the combined voting power of the Company's then
outstanding Voting Securities, increases his beneficial ownership of such
securities by 5% or more over the percentage so owned by such person on the date
hereof; or (iv) the Board adopts a resolution to the effect that, for purposes
of this Agreement, a Potential Change in Control has occurred.

   (e) Proceeding:  any threatened, pending or completed action, suit or
proceeding, or any inquiry, hearing or investigation, whether conducted by the

administrative, investigative or other.

   (f) Reviewing Party:  any appropriate person or body consisting of a member
or members of the Company's Board of Directors or any other person or body

2. AGREEMENT TO INDEMNIFY.

   (a) In the event Indemnitee was, is or becomes a party to or witness or other
participant in, or is threatened to be made a party to or witness or other
participant in, a Proceeding by reason of (or arising in part out of) an
Indemnifiable Event, the Company shall indemnify Indemnitee to the fullest
extent permitted by law, as soon as practicable but in any event no later than
thirty days after written demand is presented to the Company, against any and
all Expenses, judgments, fines, penalties and amounts paid in settlement
(including all interest, assessments and other charges paid or payable in
connection with or in respect of such Expenses, judgments, fines, penalties or
amounts paid in settlement) of such Proceeding and any federal, state, local or
foreign taxes imposed on the Indemnitee as a result of the actual or deemed
receipt of any payments under this Agreement (including the creation of the
Trust).  Notwithstanding anything in this Agreement to the contrary and except
as provided in Section 5, prior to a Change in Control Indemnitee shall not be
entitled to indemnification pursuant to this Agreement in connection with any
Proceeding initiated by Indemnitee against the Company or any director or
officer of the Company unless the Company has joined in or consented to the
initiation of such Proceeding.  If so requested by Indemnitee, the Company shall
advance (within ten business days of such request) any and all Expenses to
Indemnitee (an "Expense Advance").

   (b) Notwithstanding the foregoing, (i) the obligations of the Company under
Section 2(a) shall be subject to the condition that the Reviewing Party shall
not have determined (in a written opinion, in any case in which the special,
independent counsel referred to in Section 3 hereof is involved) that Indemnitee
would not be permitted to be indemnified under applicable law, and (ii) the
obligation of the Company to make an Expense Advance pursuant to Section 2(a)
shall be subject to the condition that, if, when and to the extent that the
Reviewing Party determines that Indemnitee would not be permitted to be so
indemnified under applicable law, the Company shall be entitled to be reimbursed
by Indemnitee (who hereby agrees to reimburse the Company) for all such amounts
theretofore paid; provided, however, that if Indemnitee has commenced legal
proceedings in a court of competent jurisdiction to secure a determination that
Indemnitee should be indemnified under applicable law, any determination made by
the Reviewing Party that Indemnitee would not be permitted to be indemnified
under applicable law shall not be binding and Indemnitee shall not be required
to reimburse the Company for any Expense Advance until a final judicial
determination is made with respect thereto (as to which all rights of appeal
therefrom have been exhausted or lapsed).  Indemnitee's obligation to reimburse
the Company for Expense Advances shall be unsecured and no interest shall be
charged thereon.  If there has not been a Change in Control the Reviewing Party
shall be selected by the Board of Directors, and if there has been such a Change
in Control (other than a Change in Control which has been approved by a majority
of the Company's Board of Directors who were directors immediately prior to such
Change in Control), the Reviewing Party shall be the special, independent
counsel referred to in Section 3 hereof.  If there has been no determination by
the Reviewing Party or if the Reviewing Party determines that Indemnitee
substantively would not be permitted to be indemnified in whole or in part under
applicable law, Indemnitee shall have the right to commence litigation in any
court in the States of California or Delaware having subject matter jurisdiction
thereof and in which venue is proper seeking an initial determination by the
court or challenging any such determination by the Reviewing Party or any aspect
thereof, and the Company hereby consents to service of process and to appear in
any such proceeding.  Any determination by the Reviewing Party otherwise shall
be conclusive and binding on the Company and Indemnitee.


3. CHANGE IN CONTROL.   The Company agrees that if there is a Change in Control
of the Company (other than a Change in Control which has been approved by a
majority of the Company's Board of Directors who were directors immediately
prior to such Change in Control) then with respect to all matters thereafter
arising concerning the rights of Indemnitee to indemnity payments and Expense
Advances under this Agreement or any other agreement or under applicable law or
the Company's
                                       3
<PAGE>
 
Certificate of Incorporation or By-Laws now or hereafter in effect relating to
indemnification for Indemnifiable Events, the Company shall seek legal advice
only from special, independent counsel selected by Indemnitee and approved by
the Company (which approval shall not be unreasonably withheld), and who has not
otherwise performed services for the Company or the Indemnitee (other than in
connection with such matters) within the last five years. Such independent
counsel shall not include any person who, under the applicable standards of
professional conduct then prevailing, would have a conflict of interest in
representing either the Company or Indemnitee in an action to determine
Indemnitee's rights under this Agreement. Such counsel, among other things,
shall render its written opinion to the Company and Indemnitee as to whether and
to what extent the Indemnitee would be permitted to be indemnified under
applicable law. The Company agrees to pay the reasonable fees of the special,
independent counsel referred to above and to indemnify fully such counsel
against any and all expenses (including attorneys' fees), claims, liabilities
and damages arising out of or relating to this Agreement or the engagement of
special, independent counsel pursuant hereto.


4. ESTABLISHMENT OF TRUST.   In the event of a Potential Change in Control, the
Company shall, upon written request by Indemnitee, create a Trust for the
benefit of the Indemnitee and from time to time upon written request of
Indemnitee shall fund such Trust in an amount sufficient to satisfy any and all
Expenses reasonably anticipated at the time of each such request to be incurred
in connection with investigating, preparing for and defending any Proceeding
relating to an Indemnifiable event, and any and all judgments, fines, penalties
and settlement amounts of any and all Proceedings relating to an Indemnifiable
Event from time to time actually paid or claimed, reasonably anticipated or
proposed to be paid.  The amount or amounts to be deposited in the Trust
pursuant to the foregoing funding obligation shall be determined by the
Reviewing Party, in any case in which the special, independent counsel referred
to above is involved.  The terms of the Trust shall provide that upon a Change
in Control (i) the Trust shall not be revoked or the principal thereof invaded,
without the written consent of the Indemnitee, (ii) the Trustee shall advance,
within ten business days of a request by the Indemnitee, any and all Expenses to
the Indemnitee (and the Indemnitee hereby agrees to reimburse the Trust under
the circumstances under which the Indemnitee would be required to reimburse the
Company under Section 2(b) of this Agreement), (iii) the Trust shall continue to
be funded by the Company in accordance with the funding obligation set forth
above, (iv) the Trustee shall promptly pay to the Indemnitee all amounts for
which the Indemnitee shall be entitled to indemnification pursuant to this
Agreement or otherwise, and (v) all unexpended funds in such Trust shall revert
to the Company upon a final determination by the Reviewing Party or a court of
competent jurisdiction, as the case may be, that the Indemnitee has been fully
indemnified under the terms of this Agreement.  The Trustee shall be chosen by
the Indemnitee.  Nothing in this Section 4 shall relieve the Company of any of
its obligations under this Agreement.  All income earned on the assets held in
the Trust shall be reported as income by the Company for federal, state, local
and foreign tax purposes.


5. INDEMNIFICATION FOR EXPENSES INCURRED IN ENFORCING THIS AGREEMENT.   The
Company shall indemnify Indemnitee against any and all expenses (including
attorneys' fees), and, if requested by Indemnitee, shall (within ten business
days of such request) advance such expenses to Indemnitee, which are incurred by
Indemnitee in connection with any claim asserted against or action brought by
Indemnitee for (i) indemnification or advance payment of Expenses by the Company
under this Agreement or any other agreement or under applicable law or the
Company's Certificate of Incorporation or By-laws now or hereafter in effect
relating to indemnification for Indemnifiable Events and/or (ii) recovery under
any directors' and officers' liability insurance policies maintained by the
Company, regardless of whether Indemnitee ultimately is determined to be
entitled to such indemnification, advance expense payment or insurance recovery,
as the case may be.
                                       4

6. PARTIAL INDEMNITY.   If Indemnitee is entitled under any provision of this
Agreement to indemnification by the Company for some or a portion of the
Expenses, judgments, fines, penalties and amounts paid in settlement of a
Proceeding but not, however, for all of the total amount thereof, the Company
shall nevertheless indemnify Indemnitee for the portion thereof to which
Indemnitee is entitled.  Moreover, notwithstanding any other provision of this
Agreement, to the extent that Indemnitee has been successful on the merits or
otherwise in defense of any or all Proceedings relating in whole or in part to
an Indemnifiable Event or in defense of any issue or matter therein, including
dismissal without prejudice, Indemnitee shall be indemnified against all
Expenses incurred in connection therewith.


7. DEFENSE TO INDEMNIFICATION, BURDEN OF PROOF AND PRESUMPTIONS.   It shall be a
defense  to any action brought by the Indemnitee against the Company to enforce
this Agreement (other than an action brought to enforce a claim for expenses
incurred in defending a Proceeding in advance of its final disposition where the
required undertaking has been tendered to the Company) that the Indemnitee has
not met the standards of conduct that make it permissible under the Delaware
General Corporation Law for the Company to indemnify the Indemnitee for the
amount claimed.  In connection with any determination by the Reviewing Party or
otherwise as to whether the Indemnitee is entitled to be indemnified hereunder,
the burden of proving such a defense shall be on the Company.  Neither the
failure of the Company (including its Board of Directors, independent legal
counsel, or its stockholders) to have made a determination prior to the
commencement of such action by the Indemnitee that indemnification of the
claimant is proper under the circumstances because he or she has met the
applicable standard of conduct set forth in the Delaware General Corporation
Law, nor an actual determination by the Company (including its Board of
Directors, independent legal counsel, or its stockholders) that the Indemnitee
had not met such applicable standard of conduct, shall be a defense to the
action or create a presumption that the Indemnitee has not met the applicable
standard of conduct.  For purposes of this Agreement, the termination of any
claim, action, suit or proceeding, by judgment, order, settlement (whether with
or without court approval) or conviction, or upon a plea of nolo contendere, or
its equivalent, shall not create a presumption that Indemnitee did not meet any
particular standard of conduct or have any particular belief or that a court has
determined that indemnification is not permitted by applicable law.


8. NON-EXCLUSIVITY.   The rights of the Indemnitee hereunder shall be in
addition to any other rights Indemnitee may have under the Company's Certificate
of Incorporation or By-laws or the Delaware General Corporation Law or
otherwise.  To the extent that a change in the Delaware General Corporation Law
(whether by statute or judicial decision) permits greater indemnification by
agreement than would be afforded currently under the Company's Certificate of
Incorporation and By-laws and this Agreement, it is the intent of the parties
hereto that Indemnitee shall enjoy by this Agreement the greater benefits so
afforded by such change.


9. LIABILITY INSURANCE.   To the extent the Company maintains an insurance
policy or policies providing directors' and officers' liability insurance,
Indemnitee shall be covered by such policy or policies, in accordance with its
or their terms, to the maximum extent of the coverage available for any Company
director or officer.


10.  PERIOD OF LIMITATIONS.   No legal action shall be brought and no cause of
action shall be asserted by or on behalf of the Company or any affiliate of the
Company against Indemnitee, Indemnitee's spouse, heirs, executors or personal or
legal representatives after the expiration of two years from the date of accrual
of such cause of action, or such longer period as may be required by state law
under the circumstances, and any claim or cause of action of the Company or
its affiliate shall be extinguished and deemed released unless asserted by the
timely filing of a legal action

                                       5
<PAGE>
 
within such period; provided, however, that if any shorter period of limitations
is otherwise applicable to any such cause of action such shorter period shall
govern.


11.  AMENDMENT OF THIS AGREEMENT.   No supplement, modification or amendment of
this Agreement shall be binding unless executed in writing by both of the
parties hereto.  No waiver of any of the provisions of this Agreement shall be
deemed or shall constitute a waiver of any other provisions hereof (whether or
not similar) nor shall such waiver constitute a continuing waiver.


12.  SUBROGATION.   In the event of payment under this Agreement, the Company
shall be subrogated to the extent of such payment to all of the rights of
recovery of Indemnitee, who shall execute all papers required and shall do
everything that may be necessary to secure such rights, including the execution
of such documents necessary to enable the Company effectively to bring suit to
enforce such rights.


13.  NO DUPLICATION OF PAYMENTS.   The Company shall not be liable under this
Agreement to make any payment in connection with any claim made against
Indemnitee to the extent Indemnitee has otherwise actually received payment
(under any insurance policy, By-law or otherwise) of the amounts otherwise
indemnifiable hereunder.


14.  SETTLEMENT OF CLAIMS.    The Company shall not be liable to indemnify
Indemnitee under this Agreement for any amounts paid in settlement of any action
or claim effected without the Company's written consent.  The Company shall not
settle any action or claim in any manner which would impose any penalty or
limitation on Indemnitee without Indemnitee's written consent.  Neither the
Company nor the Indemnitee will unreasonably withhold their consent to any
proposed settlement.  The Company shall not be liable to indemnify the
Indemnitee under this Agreement with regard to any judicial award if the Company
was not given a reasonable and timely opportunity, at its expense, to
participate in the defense of such action.


15.  BINDING EFFECT.   This Agreement shall be binding upon and inure to the
benefit of and be enforceable by the parties hereto and their respective
successors, assigns, including any direct or indirect successor by purchase,
merger, consolidation or otherwise to all or substantially all of the business
and/or assets of the Company, spouses, heirs, and personal and legal
representatives.  The Company shall require and cause any successor (whether
direct or indirect by purchase, merger, consolidation or otherwise) to all,
substantially all, or a substantial part, of the business and/or assets of the
Company, by written agreement in form and substance satisfactory to the
Indemnitee, expressly to assume and agree to perform this Agreement in the same
manner and to the same extent that the Company would be required to perform if
no such succession had taken place.  This Agreement shall continue in effect
regardless of whether Indemnitee continues to serve as a director or officer of
the Company or of any other enterprise at the Company's request.


16.  SEVERABILITY.   The provisions of this Agreement shall be severable in the
event that any of the provisions hereof (including any provision within a single
section, paragraph or sentence) is held by a court of competent jurisdiction to
be invalid, void or otherwise unenforceable, and the remaining provisions shall
remain enforceable to the fullest extent permitted by law. Furthermore, to the
fullest extent possible, the provisions of this Agreement (including, without
limitation, each portion of this Agreement containing any provision held to be
invalid, void or otherwise unenforceable, that is not itself invalid, void or
unenforceable) shall be construed so as to give effect to the intent manifested
by the provision held invalid, illegal or unenforceable.

                                       6

17.  GOVERNING LAW.   This Agreement shall be governed by and construed and
enforced in accordance with the laws of the State of Delaware applicable to
contracts made and to be performed in such State without giving effect to the
principles of conflicts of laws.



IN WITNESS WHEREOF, the parties hereto have duly executed and delivered this
Agreement as of the _______________ day of __________________, 19___.
