distributed to chain and independent drug stores, hospitals, food stores and
mass merchandisers throughout the United States and Canada. PCS provides
prescription drug claims processing and pharmacy benefit design, administration
and management to health plan sponsors. Also included in this segment are the
results of McKesson's Central American pharmaceutical operation and equity
interest in a pharmaceutical wholesale distributor in Mexico. The Health Care
Services segment generated 97% of McKesson's total revenues and 78% of its
operating profit in the nine months ended December 31, 1993 and in fiscal 1993.
McKesson's Water Products segment engages in the processing, sale and delivery
of bottled drinking water and the sale of packaged water to retail stores.
   
  In May 1993, McKesson sold 5,175,000 shares of Armor All Common Stock in a
registered public offering. As of March 2, 1994, McKesson owned 11,975,000
shares of Armor All Common Stock, or approximately 57% of Armor All's
outstanding shares, and a majority of the members of Armor All's Board of
Directors are also officers of McKesson. As a result, McKesson may be able to
control Armor All and, as a result of such control, may be able to effect
certain transactions which could result in a change in the property deliverable
upon exchange of the Debentures offered hereby. See "Description of
Debentures".

(1) Net of a $56.8 million after tax charge relating to McKesson's program to
    restructure its U.S. and Canadian health care services distribution
    businesses and the write-off of an investment.
(2) Includes $24.5 million after tax of special items relating to the gain on
    the sale and donation of Armor All Common Stock, partially offset by a
    donation to the McKesson Foundation, Inc. and a loss on the termination of
    interest rate swap arrangements.
(3) The ratio of earnings to fixed charges was computed by dividing fixed
    charges (interest expense, including the interest portion of capital and
    operating leases) into earnings available for fixed charges (income from
    continuing operations plus taxes on income and fixed charges). The ratio of
    earnings to combined fixed charges and ESOP dividend requirements was
    3.44x, 1.81x, 2.87x, 2.95x and 3.52x in 1993, 1992, 1991, 1990 and 1989,

                                   ARMOR ALL
 
  Armor All Products Corporation develops and markets branded appearance
enhancement and protection products targeted primarily for the do-it-yourself
automotive aftermarket. Its principal brand, Armor All(R), has the leading
position in the domestic automotive protectant market. A second major brand,
Rain Dance(R), is a strong competitor in the market for automotive waxes,
polishes and washes. Armor All believes that consumer awareness of its brand
names gives it a significant competitive advantage. In a recent market research
study of persons responsible for taking care of the appearance of a car, light
truck or van, 94% of the respondents were aware of the Armor All brand name.
Armor All invests substantial amounts in consumer advertising to maintain a
high level of brand awareness.
   
  Under the leadership of the senior management team assembled in fiscal 1991
and 1992, Armor All is continuing to implement its strategic plan designed to
increase domestic sales of Armor All(R) Protectant, develop and market new
automotive products, increase Armor All's international presence, and enter the
home care market.     
   
  Armor All Protectant, Armor All's principal product, is designed to protect
and beautify natural and synthetic polymer materials and is used primarily on
automobile surfaces made of rubber, vinyl and plastic, such as dashboards,
seats, door panels, tire sidewalls, vinyl tops and rubber bumpers. Armor All
Protectant is the leading protectant product in the domestic automotive
aftermarket, and Armor All believes it outsells its nearest competitor by more
than three to one. Armor All Protectant accounted for 70% of Armor All's
revenues in the nine months ended December 31, 1993 and 70% and 77% of its
revenues in fiscal 1993 and 1992, respectively. Since November 1991, Armor All
has introduced eight new products, including Armor All(R) Tire Foam(TM)
Protectant, which has become the leading product in its category since its
introduction. In December 1993, Armor All began shipping Armor All
QuickSilver(TM) Wheel Cleaner, a spray-on cleaner designed for use on
automotive wheels, wheel covers and hubcaps; Armor All Protectant Low-Gloss
Natural Finish(TM), a low-gloss version of Armor All Protectant designed to
minimize dashboard glare for consumers who prefer a less shiny appearance; and
Armor All Spot & Wash(TM) Concentrate, a car wash product designed to remove
bugs, tar residue and tree sap from car finishes. These products will be
supported by national television advertising and by special introductory
pricing and promotional programs. In January 1994, Armor All also acquired the
E-Z Deck Wash(R) product, which cleans and restores wood surfaces.     
 
  Armor All's products are marketed in the United States and Canada by its
direct sales force and also through independent manufacturers' representatives
and distributors. Primary customers include mass merchandise retailers, auto
supply stores, warehouse clubs, hardware stores and other retail outlets in the
United States and certain foreign markets. Armor All believes that its products
are sold at over 100,000 retail outlets. In the nine months ended December 31,
1993, sales to Armor All's two largest customers, Wal-Mart Stores, Inc. (and
its affiliates) and Kmart Corporation (and its affiliates), accounted for 15%
and 8%, respectively, of Armor All's revenues. In fiscal 1993, sales to these
same two customers represented 15% and 11%, respectively, of Armor All's
revenues. International sales represented 15% and 12% of Armor All's revenues
in the nine months ended December 31, 1993 and in fiscal 1993, respectively.
Armor All is seeking to expand its international presence, in part through a
marketing and distribution alliance with S.C. Johnson & Son, Inc. ("S.C.
Johnson").
 
  Armor All's products are mixed and packaged by contract packagers. Armor
All's use of packagers permits it to reduce its fixed capital requirements,
limit its employment needs, and minimize its investment in product inventory
because its packagers own most raw materials and finished products until
shipment to Armor All's customers.

                                USE OF PROCEEDS
   
  The net proceeds from the sale of the Debentures are estimated to be $177.9
million ($197.7 million, if the Underwriters' over-allotment option is
exercised in full). McKesson intends to use the net proceeds to repay a portion

          MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                     AND RESULTS OF OPERATIONS OF ARMOR ALL
 
RESULTS OF OPERATIONS
 
  Net income for the nine months ended December 31, 1993 increased 18% from the
corresponding period in the prior year, and net income in fiscal 1993 and 1992
increased 49% and 88% from the respective prior years. These improvements were
primarily due to higher revenues from both existing and new products, as well
as to improved promotional and administrative cost efficiencies.

</TABLE>
 
  Substantially all of the $5.2 million increase in Armor All's U.S. revenues
in the nine months ended December 31, 1993 in comparison with the prior-year
period resulted from higher sales of Armor All(R) Tire Foam(TM) Protectant,
which has become the leader in its category since its introduction in November
1991, and Rain Dance(R) Dark Car Formula Polish and Rain Dance(R) Light Car
Formula Polish, which were introduced in January 1993, and from initial sales
of Armor All QuickSilver(TM) Wheel Cleaner, Armor All Protectant Low-Gloss
Natural Finish(TM) and Armor All Spot & Wash(TM) Concentrate in December 1993.
The $3.8 million increase in international revenues in the nine-month period
reflects higher sales in each of Armor All's principal foreign markets: Canada,
Europe, Asia, Latin America and Australia.
 
  Approximately half of the increase in Armor All's U.S. revenues in fiscal
1993 from fiscal 1992 was due to higher sales of Armor All Tire Foam
Protectant. In part because trade customers were still reducing their retail
inventory levels during the first two quarters of fiscal 1992, sales of Armor
All Protectant also increased in fiscal 1993. The introduction of Armor All
Protectant with additional sunscreen in January 1993, accompanied by a 5%
selling price increase, also contributed to higher sales in the fourth quarter.
Sales of Armor All's line of waxes and washes rose moderately in fiscal 1993,
mainly due to higher sales of Rain Dance(R) Advanced Formula Car Polish, which
was introduced in November 1991, and initial sales of Rain Dance Dark Car
Formula Polish and Rain Dance Light Car Formula Polish.
 
  The increase in Armor All's U.S. revenues in fiscal 1992 from fiscal 1991 was
primarily attributable to higher sales of Armor All Protectant. This
improvement resulted from several factors, including increased consumer demand
and the effect of changes in Armor All's trade management practices initiated
at the end of fiscal 1990. In March 1990, Armor All discontinued certain trade
promotions and pricing practices that encouraged inventory buildups by trade
customers. These high retail inventory levels in turn dampened sales by Armor
All in fiscal 1991. In addition, during the second half of fiscal 1991, Armor
All's retail customers were extremely cautious in their purchasing practices in
response to the deepening economic recession and the outbreak of war in the
Middle East. In fiscal 1992, Armor All strengthened its support of key
customers' inventory management and promotional efforts, in part by initiating
electronic data interchange links with retailers. Also contributing to the
increased revenues in fiscal 1992 was the introduction of three new products in
November 1991: Armor All Tire Foam Protectant, Armor All Leather Care(TM)
Protectant and Rain Dance Advanced Formula Car Polish. Sales of Armor All's
line of waxes and washes declined slightly, primarily due to the discontinuance
of certain products.
 
  The increase in international revenues of $0.5 million in fiscal 1993 and the
decrease in fiscal 1992 were due to several, sometimes offsetting, factors. One
significant factor affecting both fiscal 1993 and 1992 in several countries,
notably Japan and Germany, was the distribution agreement with S.C. Johnson,
which was
 
                                       15
<PAGE>
 
entered into in September 1991. Under the agreement, which is effective through
June 2001, S.C. Johnson has the right to distribute Armor All (R) Protectant
and certain of Armor All's other products in a number of international markets
on a country-by-country basis, subject to agreement with Armor All on a
business and marketing plan for each country and thereafter the attainment of
certain performance targets. Armor All and S.C. Johnson share in the profits or
losses on sales in these markets. Sales are at much lower prices to S.C.
Johnson, which incurs virtually all associated selling and marketing expenses
previously borne by Armor All. The net effect is that Armor All records lower
revenues and selling and marketing expenses.
 
  Offsetting the S.C. Johnson impact, international revenues in fiscal 1993
benefited from increased sales to its largest Canadian customer, which had
reduced its high inventory levels of the previous year, and increased market
penetration in Asia, Latin America and the United Kingdom. On the other hand,
sales were adversely affected in Germany due to the economic recession in that
country. In addition to the S.C. Johnson effects, international revenues
decreased in fiscal 1992, primarily because Armor All's largest Canadian
customer slowed purchases while working down high retail inventory levels.

</TABLE>
 
  Cost of sales as a percentage of revenues was unchanged in the nine months
ended December 31, 1993 in comparison with the prior-year period due to the
effects of several offsetting factors. The cost percentage was increased by
changes in the product mix, higher shipments of certain promotional items and
the higher cost of the additional-sunscreen formula for Armor All Protectant.
However, the effect of these factors was offset by the 5% selling price
increase on Armor All Protectant and the absorption of fixed manufacturing and
distribution costs over a higher sales volume.
 
  Cost of sales as a percentage of revenues in fiscal 1993 was unchanged from
fiscal 1992 due to the effects of several offsetting factors. The cost
percentage was increased slightly due to changes in the product mix and higher
sales of certain promotional items. Additionally, margins were lower in the
markets served by S.C. Johnson due to the billing method described above under
"Revenues." However, the effect of these factors was offset as fixed
manufacturing and distribution costs were absorbed over a higher sales volume.
 
  The decrease in cost of sales as a percentage of revenues in fiscal 1992 from
fiscal 1991 was partially due to a favorable shift in the product mix, with a
greater proportion of higher-margin sales of Armor All Protectant than sales of
Armor All's waxes and washes. In addition, Armor All did not repeat a lower-
margin promotional program. Armor All also incurred lower freight costs and was
able to spread its fixed manufacturing and distribution costs over a higher
sales volume.
 
  The decrease in selling, general and administrative (SG&A) expenses as a
percentage of revenues in the nine months ended December 31, 1993 from the
prior-year period was principally due to the absorption of media advertising
and fixed administrative expenses over a higher sales volume, partially offset
by the introduction of several new consumer promotions.
 
  SG&A expenses as a percentage of revenues decreased in fiscal 1993 from
fiscal 1992 primarily due to more efficient trade promotion practices.
Beginning in late fiscal 1992, Armor All implemented a new trade promotion
approach in which Armor All offers its trade customers fixed sums in return for
specific
 
                                       16
<PAGE>
   
promotional activities. Also contributing to the decrease was the spreading of
fixed administrative expenses over a higher sales volume. The S.C. Johnson
agreement reduced fiscal 1993 SG&A expenses, as noted above. In addition,
fiscal 1992 was adversely affected by expenses associated with certain
litigation settled in that year. Partially offsetting these factors were
increased expenditures in fiscal 1993 on media advertising and certain consumer
promotions in the United States.
 
  The decrease in SG&A expenses as a percentage of revenues in fiscal 1992 from
fiscal 1991 was principally due to lower advertising expenditures for waxes.
Also contributing to the decrease were the spreading of fixed administrative
expenses over a higher sales volume and lower trade marketing expenses under
the new approach described above. These factors were partially offset by the
implementation of several new consumer promotional programs.
 
  Amortization expense, principally relating to intangible assets associated
with Armor All's acquisition of several brands in September 1988, declined by
$0.9 million in the nine months ended December 31, 1993 and by $0.5 million in
fiscal 1993, and is expected to decline further in fiscal 1995 as certain of
such assets become fully amortized.
 
  Interest income increased by $0.2 million in the nine months ended December
31, 1993 and by $0.2 million in fiscal 1993 due to higher cash balances during
those periods. Cash balances increased primarily as a result of profitable
operations without significant investments in working capital or fixed assets.
However, the effect of the improved cash position was partially offset by lower
interest rates. Net interest income increased by $1.8 million in fiscal 1992
from fiscal 1991, also primarily because of higher cash balances. The
improvement in Armor All's cash position in that year was largely due to
management's decision to shorten customer payment terms during the winter
promotional season.
 
  Armor All's effective income tax rates were 43.2% and 41.9% in the nine
months ended December 31, 1993 and 1992, respectively. The higher effective
rate in the current nine-month period principally reflects the enactment of the
Omnibus Budget Reconciliation Act of 1993, which increased the federal
corporate income tax rate from 34% to 35% retroactive to January 1993.
Approximately 0.4% of the increase represents the additional taxes which will
be paid for the fiscal year ended March 31, 1993 due to the retroactive
provision of the Act. Armor All's effective income tax rates were 42.6%, 42.8%
and 46.0% in fiscal 1993, 1992 and 1991, respectively. The tax rate in fiscal
1991 was relatively high because a greater proportion of Armor All's expenses
was composed of nondeductible intangible asset amortization and foreign

  Armor All's revenues typically peak in the fourth fiscal quarter (from
January through March) as customers purchase inventory to prepare for increased
consumer purchasing activity in the spring and summer. Interest income is
generally highest in the summer and autumn, due to the improvement in Armor
All's cash position which accompanies the collection of receivables associated
with fourth and first quarter sales. Quarterly results may also be affected by
Armor All's method of allocating annual media advertising expenses and certain
trade promotional expenses among interim periods in proportion to estimated
annual sales volume.
 
FINANCIAL RESOURCES AND LIQUIDITY
 
  Armor All's working capital requirements fluctuate during the year,
traditionally peaking in the spring due to extended payment terms offered to
customers in connection with winter promotional activities. Cash inflow is
strongest during the summer months as these receivables are collected.
Reflecting these seasonal factors, at December 31, 1993, Armor All had balances
of cash and cash equivalents of $53.2 million and no short-term or long-term
debt. At December 31, 1993, Armor All had working capital of $65.3 million.
 
  Armor All does not have substantial investments in inventory as its contract
packagers generally own the raw materials and finished goods in their
possession and transfer title to Armor All just prior to shipment to Armor
All's customers. Armor All's use of contract packagers also permits it to avoid
significant investments in machinery and other fixed assets. See "Business of
Armor All-Manufacturing and Packaging."
 
  During the nine months ended December 31, 1993 and 1992, respectively, cash
flow from operations was $31.7 million and $37.2 million. Despite higher net
income in the current period, cash flow from operations was lower due to the
timing of payments for income taxes and certain accrued advertising and selling
expenses. During fiscal 1993 and 1992, cash flow from operations was $24.7
million and $30.4 million, respectively. Cash flow from operations declined in
fiscal 1993, despite a higher net income, primarily due to the increase in
receivables associated with the higher fourth quarter sales volume. Cash
outflows for investing activities during the two years were relatively small,
as Armor All did not have significant capital expenditures. In addition, Armor
All paid dividends on its Common Stock of $9.3 million in the nine months ended
December 31, 1993, $10.1 million in fiscal 1993 and $10.9 million in fiscal
1992.
 
  Armor All's sources of liquidity at December 31, 1993 included a $48.8
million balance under a cash management program administered by McKesson, $4.4
million of other cash balances, and a $3.0 million (Canadian) line of credit
with a Canadian bank that is renewable annually. In addition, as long as Armor
All continues to participate in the cash management program, McKesson will make
available the cash necessary to provide Armor All with sufficient funds to meet
its needs as defined in its annual capital and operating plans. There are no
advance notification requirements or other limitations on Armor All's access to
cash under the program. Participation in the cash management program is
provided as part of a Services Agreement with McKesson, and amounts deposited
under the program are deposited in a separate bank account in Armor All's name.
See "Certain Relationships and Transactions." In the event that Armor All
ceases to participate in the cash management program, Armor All believes that
it would be able to obtain a line of credit from other sources at competitive
terms. At December 31, 1993, Armor All had a payable to McKesson of $1.2
million for payroll, freight and other expenses paid by McKesson on Armor All's
behalf; Armor All repaid this amount in January 1994.
 
  Armor All believes that its current sources of liquidity, combined with cash
flow from operations, will be sufficient to meet its needs for the foreseeable
future.

                             BUSINESS OF ARMOR ALL
 
  Armor All Products Corporation develops and markets a broad line of branded
appearance enhancement and protection products targeted primarily for the do-
it-yourself automotive aftermarket. Its principal brand, Armor All(R), has the
leading position in the domestic automotive protectant market. A second major
brand, Rain Dance(R), is a strong competitor in the market for automotive
waxes, polishes and washes. Armor All believes that consumer awareness of its
brand names gives it a significant competitive advantage. In a September 1993
study conducted by a market research and consulting firm, which involved a
national sampling of approximately 460 persons aged 16 to 54 years who were
responsible for taking care of the appearance of a car, light truck or van (the
"1993 Market Research Study"), 94% of the respondents were aware of the Armor
All brand name (either unprompted or when given name and product attributes).
 
BUSINESS STRATEGY
   
  Under the leadership of the senior management team assembled in fiscal 1991
and 1992, Armor All has adopted and is continuing to implement a strategic
business plan to build on the strength of Armor All's well-established brand
names to increase domestic sales of Armor All Protectant, introduce new
automotive products, increase Armor All's international presence, and enter the
home care market.     
 
 Increase Domestic Sales of Armor All Protectant
 
  Armor All seeks to increase sales of Armor All Protectant through targeted
advertising and promotion to enlarge the user base, increase the frequency of
product use, and expand the number of surfaces on which the product is applied.
Armor All believes that sales of Armor All Protectant represent approximately
two-thirds of all domestic sales of automotive protectants. According to the
1993 Market Research Study, 99% of all respondents who were current users of
Armor All Protectant expressed satisfaction with the product, with 70%
indicating that they were "very" satisfied with it. While 59% of the
respondents had used Armor All Protectant during the preceding six months, 35%
had used no protectant product, which Armor All believes demonstrates an
opportunity to expand the user base.
   
  As part of its plan to expand the protectant market, Armor All intends to add
line extensions to attract new users. In December 1993, Armor All introduced a
new product, Armor All Protectant Low-Gloss Natural Finish(TM), described
below.     
   
 Introduce New Automotive Products     
 
  Since November 1991, Armor All has introduced eight new products, including
Armor All Tire Foam (TM) Protectant, which together accounted for approximately
15% of revenues in the nine months ended December 31, 1993 and for
approximately 13% of revenues in the fiscal year ended March 31, 1993. In
December 1993, Armor All began shipping Armor All QuickSilver(TM) Wheel
Cleaner, a spray-on wheel cleaner designed for use on wheels, wheel covers and
hubcaps; Armor All Protectant Low-Gloss Natural Finish(TM), a low-gloss version
of Armor All Protectant designed to minimize dashboard glare for consumers who
prefer a less shiny appearance; and Armor All Spot & Wash(TM) Concentrate, a
car wash product designed to remove bugs, tar residue and tree sap from car
finishes. These products will be supported by national television advertising
and by special introductory pricing and promotional programs.
   
  Armor All intends to continue to develop new products and product line
extensions under its well-established Armor All and Rain Dance brand names. To
that end, Armor All's research and development and marketing personnel seek to
develop and acquire promising technologies and invest in consumer market
research. Armor All also seeks to anticipate industry trends that affect care
of automotive surfaces, such as increased exposure of automobile interiors to
sunlight, use of leather upholstery, and changes in vinyls, rubbers, paints and
other automotive surfaces.     
 
 Increase International Presence
 
  Armor All's management believes that foreign markets will, over time, present
a significant growth opportunity for the company. Armor All Protectant already
enjoys a leading position in several international
 
                                       19
<PAGE>
 
markets, including Canada, Australia and Mexico. International sales are
effected through sales offices in Canada and the United Kingdom, through
foreign distributors, and through a marketing and distribution alliance with
S.C. Johnson. The S.C. Johnson arrangement provides Armor All with access to
certain international markets, primarily Germany, Japan and Mexico, without the
high selling and marketing costs incurred in a direct sales program. However,
Armor All plans to continue identifying foreign markets attractive for direct
sales or distribution by entities other than S.C. Johnson, based on a number of
factors, including economic, political and competitive conditions, cultural and
demographic trends, and car care habits.
   
 Enter the Home Care Market     
   
  Armor All's management believes that the home care market represents a growth
opportunity for Armor All. Armor All has established a new division intended to
utilize its marketing and new product development strengths to penetrate this
market. On January 28, 1994, Armor All acquired the E-Z Deck Wash(R) brand. The
E-Z Deck Wash product cleans and restores wood surfaces such as decks and
siding and will be marketed under the Armor All name. An application for patent
protection on the E-Z Deck Wash formula is pending.     
 
PRODUCTS
 
  Armor All markets a broad line of automotive appearance chemicals under four
brand names: Armor All(R) , Rain Dance(R) , Rally(R) and No. 7(R) .
 
 Armor All Brand
 
  Armor All markets protectants, waxes, washes and other cleaning aids under
the Armor All name.
 
  Armor All's principal product, Armor All Protectant, is designed to protect
and beautify natural and synthetic polymer materials and is primarily used on
automobile surfaces made of rubber, vinyl and plastic, such as dashboards,
seats, vinyl tops, door panels, tire sidewalls and rubber bumpers. Armor All
Protectant is the leading protectant product in the domestic automotive
aftermarket, and Armor All believes it outsells its nearest competitor by more
than three to one. Armor All Protectant accounted for 70% of Armor All's
revenues in the nine months ended December 31, 1993 and for 70% and 77% of its
revenues in fiscal 1993 and 1992, respectively.
 
  Armor All Tire Foam Protectant, introduced in November 1991, cleans, shines
and protects tire sidewalls without wiping. Sales of this product represented a
majority of the revenues attributable to new products in the nine months ended
December 31, 1993 and fiscal 1993. Armor All Leather Care (TM) Protectant, also
introduced in November 1991, is designed primarily for leather upholstery.
Armor All also markets a liquid car wax, a multi-purpose cleaner, and a car
wash liquid concentrate under the Armor All name.
 
  In December 1993, Armor All started shipping three additions to the Armor All
product line: Armor All QuickSilver (TM) Wheel Cleaner, Armor All Protectant
Low-Gloss Natural Finish (TM) and Armor All Spot & Wash (TM) Concentrate.
 
 Rain Dance Brand
 
  Armor All markets polishes, waxes and car wash products under the Rain Dance
name. In November 1991, Armor All introduced Rain Dance Advanced Formula Car
Polish, and in January 1993, Armor All introduced two additional car polishes,
Rain Dance Light Car Formula Polish and Rain Dance Dark Car Formula Polish,
with different light reflectant characteristics. Liquid and paste car wax and a
variety of car wash products are also marketed under the Rain Dance name.
 
 Rally and No. 7 Brands
 
  Armor All markets cream and liquid waxes under the Rally name. Under the No.
7 name, Armor All markets a variety of polishing and rubbing compounds and
other cleaning aids.
 
                                       20

GEOGRAPHIC MARKETS
 
  Armor All's products are sold predominantly in the United States and Canada,
with additional sales occurring in several other countries. In the nine months
ended December 31, 1993, 85% of sales were in the United States, 6% in Canada
and 9% in other foreign countries, principally Australia, Germany, Japan,
Mexico and the United Kingdom. In fiscal 1993, 88% of sales were in the United
States, 5% in Canada and 7% in other foreign countries. Armor All does not have
large fixed capital investments in its foreign operations. Foreign currency
exchange fluctuations have not had a significant impact on Armor All's
operating results.
 
SALES AND MARKETING
 
  In the United States and Canada, a sales force of 13 employees accounted
directly for over 50% of revenues in the first nine months of fiscal 1994 and
in fiscal 1993. In addition, Armor All's sales force oversees 21 independent
manufacturers' representative organizations that also market Armor All's
products. Primary customers include mass merchandise retailers, auto supply
stores, warehouse clubs, hardware stores and other retail outlets. Armor All
believes that its products are sold at over 100,000 retail outlets.
 
  Armor All's largest customers have represented an increasing percentage of
its revenues. Sales to Armor All's 20 largest customers accounted for 64% of
Armor All's consolidated revenues in the nine months ended December 31, 1993
and for 63%, 59% and 49% of Armor All's consolidated revenues in fiscal 1993,
1992 and 1991, respectively. In the nine months ended December 31, 1993, sales
to Armor All's two largest customers, Wal-Mart Stores, Inc. (and its
affiliates) and Kmart Corporation (and its affiliates), accounted for 15% and
8%, respectively, of Armor All's revenues. In fiscal 1993, sales to these same
two customers accounted for 15% and 11%, respectively, of Armor All's revenues.
 
  Armor All's direct sales force works closely with customers on joint
marketing and promotional activities. Armor All also assists its customers with
inventory management. Its efforts to help customers manage their inventories
are supported, in certain cases, by electronic data interchange ("EDI") links
between Armor All and the customer. In addition, EDI provides Armor All with
valuable marketing information. Among other things, Armor All uses EDI point-
of-sale statistics to analyze geographic purchasing patterns, measure the
success of test marketing programs and monitor sales of holiday gift packs and
other time-sensitive promotions. Armor All intends to establish additional EDI
links with its customers and to expand the use of existing links.
   
  Armor All's management assists in sales and marketing efforts by providing
national advertising and promotional support and retail merchandising
management assistance, including product information and sales training.
Although Armor All's promotional activities target both trade accounts and
retail consumers, Armor All has increased the proportion of marketing funds
devoted to consumer promotion over the last three years. Armor All has also
increased the proportion of its marketing expenses which are offered to trade
customers as fixed sums in return for specific promotional activities, as
opposed to more general cooperative advertising arrangements. From time to
time, Armor All uses various retail sales incentive devices, such as coupons,
rebates, "Bonus Packs" (e.g., 20 ounces for the price of 16), merchandise with
attached free samples, and other special offers to stimulate retail sales.     
 
  Armor All believes that it invests more in consumer advertising than do its
competitors in the automotive appearance chemicals industry. Management
attempts to allocate Armor All's advertising spending among media which provide
the greatest potential exposure to desired audiences per dollar. Armor All
intends to continue to invest in consumer advertising to maintain the high
level of consumer brand awareness which Armor All currently enjoys.
 
  Retail sales of Armor All's products are seasonal and are highest between
April and September. However, sales to Armor All's customers are highest in its
fourth fiscal quarter (from January through March). Consistent with industry
practice, Armor All offers extended payment terms in conjunction with its
winter promotional activities.
 
                                       21
<PAGE>
 
  International sales are effected through sales offices in Canada and the
United Kingdom, through foreign distributors, and through a marketing and
distribution alliance with S.C. Johnson. Under an agreement between Armor All
and S.C. Johnson, S.C. Johnson is the exclusive distributor of Armor All
Protectant and certain of Armor All's other products in Germany, Japan and
Mexico, subject to agreement with Armor All on annual business and marketing
plans for each country. Under the agreement, S.C. Johnson pays virtually all
selling and marketing expenses, and Armor All and S.C. Johnson share in the
profits or losses. The S.C. Johnson agreement expires in June 2001, with
automatic five-year renewals unless either party provides 12 months' prior
notice. Armor All will have the right to terminate the agreement on a country-
by-country basis if S.C. Johnson fails to meet certain revenue objectives over
specified periods, subject to S.C. Johnson's right to avoid termination by
compensating Armor All for any shortfall. S.C. Johnson is also the exclusive
distributor of Armor All (R) Protectant in several Southeast Asian countries
under separate agreements that do not involve profit or loss sharing.
 
MANUFACTURING AND PACKAGING
 
  Armor All's products are manufactured by contract packagers. Armor All's
relationships with its two most important packagers have lasted for 8 and 20
years, respectively. Subject to contractual arrangements, Armor All
periodically reevaluates its selection of packagers, and believes that other
acceptable packagers are readily available.
 
  Armor All avoids significant investments in inventory. In general, Armor
All's full-service packagers are responsible for purchasing product ingredients
and approved component packaging materials. Armor All negotiates the raw
material supply arrangements on behalf of its packagers. The packagers blend,
package and warehouse the finished product. With certain exceptions, the full-
service packagers own all the raw materials and finished products in their
possession and transfer title to Armor All just prior to shipment to Armor
All's customers. In the case of Armor All Protectant, Armor All premixes a
concentrate which it sells to the full-service packagers. For certain products,
Armor All has title to raw materials and finished products and pays a
manufacturing fee to the packager.
 
  Armor All's products are manufactured in four principal locations in the
United States, one location in Canada and one location in Australia.
Protectants are manufactured at five of these locations, and waxes at the
sixth. Armor All's management believes that the existing packagers can
accommodate Armor All's production needs for the foreseeable future.
 
  Armor All has alternative sources for the ingredients used in, and packaging
components for, all of its products. Armor All has contracts with certain
suppliers to provide a continued supply of the primary chemical ingredients and
packaging components used in producing its products, which expire by their
terms on various dates through March 1995.
 
TRADEMARKS AND PATENTS
 
  Armor All's principal trademarks are: The ARMOR ALL(R) trademark, the symbol
of a male VIKING figure surrounded by a rainbow design, the RAIN DANCE(R)
trademark, the RALLY(R) trademark and the NO. 7(R) trademark. Armor All also
owns other registered and unregistered trademarks. All five principal
trademarks are registered in the United States and Canada. In addition, the
ARMOR ALL trademark is registered in 82 countries, the VIKING trademark is
registered in 83 countries, the RAIN DANCE trademark is registered in 55
countries, the RALLY trademark is registered in 35 countries and the NO. 7
trademark is registered in 3 countries. Armor All believes it has taken all
necessary steps to preserve the registration of its trademarks. Armor All also
owns a process patent on ARMOR ALL Protectant and a patent on RAIN DANCE wax,
and has applied for patents on ARMOR ALL QuickSilver(TM) Wheel Cleaner and
ARMOR ALL Spot & Wash(TM) Concentrate. Armor All's process patent on ARMOR ALL
Protectant will expire in 1996. Armor All's management believes that Armor
All's trademarks are more important assets than its patents, and that the
termination or invalidity of its patents would not have a materially adverse
effect on Armor All.
 
                                       22
<PAGE>
  
COMPETITION
 
  In the domestic protectant market, Armor All has two principal competitors,
STP Son-of-a-Gun(R) Protectant and Turtle Wax Formula 2001(R), and several
secondary competitors. Armor All estimates that domestic sales of Armor All
Protectant account for approximately two-thirds of all domestic protectant
sales. Armor All Tire Foam Protectant has two principal competitors, No
Touch(R) and STP Son-of-a-Gun(R) Tire Care, and several secondary competitors.
Armor All brand cleaner competes against many specialty automotive cleaner
products. Armor All brand wax and wash products and all of the Rain Dance and
Rally brand products compete with numerous wash, wax and polish products in the
automotive aftermarket. The No. 7 brand products compete with many wash and
specialty cleaning products. Competition in international markets varies by
country.
 
  Armor All believes that brand recognition and loyalty, access to retail shelf
space, product convenience and effectiveness, trade promotion and consumer
advertising, support of customers' inventory management and marketing efforts,
and pricing are important competitive factors in the appearance protection
market. Armor All believes that it competes favorably with respect to these
factors.
 
EMPLOYEES
 
  At December 31, 1993, Armor All employed 127 persons. None of Armor All's
employees is represented by a union. Armor All believes its employee relations
are good.
 
PROPERTIES
 
  Armor All owns its headquarters facility located in Aliso Viejo, California.
The facility, which was built in 1989, comprises 45,000 square feet of office
space on a 4.6 acre site.
 
  Armor All also leases approximately 17,000 square feet of warehouse space in
Aliso Viejo, California. The facility is used primarily for warehousing certain
components, finished goods and promotional items. Armor All also mixes the
Armor All Protectant concentrate and performs various special product-packaging
functions at this location. Armor All also utilizes limited space in various
public warehouses in the United States and abroad for temporary inventory
storage and shipping.
 
  Armor All maintains sales offices in Canada and the United Kingdom, each with
less than 2,000 square feet. It conducts its laboratory research and
development activities at a leased facility of approximately 5,000 square feet
located near Armor All's headquarters in Aliso Viejo, California.
 
  Armor All believes that these properties will be sufficient to meet its needs
for the next several years.

                     CERTAIN RELATIONSHIPS AND TRANSACTIONS
 
  On July 1, 1986, Armor All entered into a Services Agreement (the "Services
Agreement") with a subsidiary of McKesson. Pursuant to the Services Agreement,
McKesson has agreed to provide to Armor All, and Armor All has agreed to
purchase, certain corporate staff services. For fiscal 1992, fiscal 1993 and
the first nine months of fiscal 1994, the amount charged Armor All by McKesson
for such services was $566,000, $622,000 and $448,000, respectively, exclusive
of insurance and outside professional services that are billed separately.
Armor All believes that these expenses would not have been materially different
if Armor All operated on a stand-alone basis. These charges are modified
annually to reflect changes in McKesson's costs of providing these services.
The services provided by McKesson include treasury and financial, risk
management support, legal, corporate secretary, investor relations, tax,
internal audit, planning and corporate development, accounting advice, and
employee benefit, personnel and payroll services. Armor All can request, and
McKesson may provide, data processing, computer programming and other services
to supplement the capabilities of Armor All. McKesson has agreed to make
available to Armor All certain employee benefit plans and also has agreed to
allow Armor All employees to continue to participate in McKesson's retirement
plan and employee stock ownership plans. Armor All has agreed to contribute
annually to the plans the amount necessary to fund employee participation.
Armor All is also insured under McKesson's property and casualty insurance
program for limits of liability and deductibles deemed appropriate for Armor
All's risk exposures and size. Premiums are based on Armor All's risk exposure
and historical loss experience.
 
  The Services Agreement is automatically renewed for successive one-year terms
unless terminated and is reviewed annually by Armor All's Chief Financial
Officer with Armor All's independent directors. The Services Agreement will be
terminated if McKesson should own less than fifty percent of the outstanding
voting stock of Armor All, or upon 120 days' prior written notice by either
party, or upon such earlier date as the parties may mutually agree in writing.
The Services Agreement provides that McKesson's liability with respect to any
loss or damages arising in connection with the provision of services to Armor
All is limited to amounts billed or billable for such services.
 
  Pursuant to the Services Agreement, Armor All's U.S. operations participate
on a daily basis in a cash management program administered by McKesson. Under
this arrangement, Armor All invests any excess
 
                                       26
<PAGE>
 
cash under the cash management program, has unrestricted access to the cash
invested and meets cash requirements through borrowings from McKesson. Prior to
March 23, 1993, Armor All invested excess cash with McKesson. Effective on that
date, all amounts invested with McKesson were deposited in a separate bank
account in Armor All's name. Armor All receives interest under the program
through McKesson on funds deposited in the separate bank account, or pays
interest to McKesson on funds received, at a rate equal to the monthly Federal
Reserve Composite Rate for 7-day commercial paper less one-tenth of one percent
for funds deposited under the program and plus one-half of one percent for
funds borrowed from McKesson. The Services Agreement provides that McKesson
will make available that amount of cash necessary to provide Armor All with
sufficient funds to meet its needs as defined in its annual capital and
operating budget, and that Armor All will pay McKesson an annual credit
facility fee of $25,000. At December 31, 1993, Armor All had invested
$48,793,000 under the cash management program at an interest rate of 3.1%.
During most of fiscal 1993, Armor All also had a $3,000,000 (Canadian) demand
note receivable from a Canadian subsidiary of McKesson. The demand note was
repaid in March 1993. The maximum amount invested by Armor All under the cash
management program at any month-end during fiscal 1992 and 1993 and the first
nine months of fiscal 1994 was $23,239,000, $41,900,000 and $51,396,000,
respectively. In fiscal 1992 and 1993 and the first nine months of fiscal 1994,
Armor All received from McKesson net interest in the amount of $764,000,
$1,113,000 and $948,000, respectively, pursuant to this arrangement.
 
  At December 31, 1993, Armor All had a payable to McKesson of $1,150,000 for
payroll, freight and other expenses paid by McKesson on Armor All's behalf;
Armor All repaid this amount in January 1994. Before establishing its own cash
management bank account in March 1993, Armor All reimbursed McKesson for such
items through automatic transfers from Armor All's amounts on deposit with
McKesson under the cash management program.
 
  Sales by Armor All to divisions of McKesson were $654,000, $889,000, and
$1,111,000 in fiscal 1991, 1992 and 1993, respectively, and $575,000 in the
nine months ended December 31, 1993.
 
  Under the terms of the Acquisition Agreement dated July 1, 1986 pursuant to
which McKesson transferred the business of its Armor All Products Division to
Armor All, McKesson and Armor All have agreed that McKesson has no obligation
to refer to Armor All ideas or products whether or not related to appearance
protection products applicable to the automotive aftermarket. McKesson is not
obligated to fund, or permit Armor All to fund, development of any product or
idea, if McKesson concludes that such development is not in Armor All's best
interests.
 
  Armor All is included in McKesson's consolidated federal income tax returns
for tax periods ending before May 19, 1993. Pursuant to a Tax Allocation
Agreement dated as of July 1, 1986 between Armor All and McKesson (the "Tax
Allocation Agreement"), adjustments to federal income tax liabilities for
periods in which Armor All was included in McKesson's consolidated federal
income tax returns are allocated between Armor All and the other businesses
conducted by McKesson and its affiliates. The agreement requires Armor All to
reimburse McKesson for any tax audit adjustment of taxes attributable to it
which were reported on McKesson's consolidated federal income tax returns. Tax
refunds will be the property of the party bearing economic responsibility for
the applicable tax. The Tax Allocation Agreement also provides for the
allocation of state franchise or corporate income taxes which Armor All and
McKesson are required or permitted to pay on a combined or "unitary" basis so
that, in general, Armor All is treated as a separate taxpayer.
   
  As of March 2, 1994, McKesson owned 11,975,000 shares of Armor All Common
Stock, representing approximately 57% of all outstanding shares. In May 1993,
McKesson sold 5,175,000 shares of Armor All Common Stock in an underwritten
public offering. If all of the Debentures offered hereby were exchanged for
shares of Armor All Common Stock, McKesson would own        shares of Armor All
Common Stock, representing approximately    % of the shares of Armor All Common
Stock outstanding on the above date.

                       DESCRIPTION OF THE DEBENTURES     
   
  The Debentures will be issued under an Indenture (the "Indenture") dated as
of March , 1994 between McKesson and The First National Bank of Chicago, as
trustee (the "Trustee"). The following description of the terms of the
Debentures is subject to the detailed provisions of the Indenture and is
qualified in its entirety by reference to the Indenture, a copy of which is an
exhibit to the Registration Statement. Capitalized terms not defined herein
have the meanings ascribed to them in the Indenture.     
   
GENERAL     
   
  The Debentures will constitute unsecured general obligations of McKesson
subordinate in right of payment to certain other obligations of McKesson and
will be exchangeable, at the option of the holder, for shares of Armor All
Common Stock and/or other property attributable to such shares (collectively,
the "Exchange Property"). See "Subordination" and "Exchange Rights" below.
However, in lieu of delivering Exchange Property upon surrender of a Debenture
for exchange, McKesson may at its option pay cash equal to the value of the
Exchange Property. See "Exchange Rights--McKesson's Cash Option on Exchange"
below. As used in the Indenture, the term "Exchange Property" means initially
the      fully paid and nonassessable shares of Armor All Common Stock
delivered to the Exchange Agent by McKesson pursuant to the Exchange Agent
Agreement simultaneously with the execution and delivery of the Indenture, and
thereafter may also include such other securities, cash or other property
attributable to the Armor All Common Stock or other Exchange Property, which at
the time are deliverable upon surrender of the Debentures for exchange.     
   
  The Debentures will be limited to $200,000,000 aggregate principal amount
(including $20,000,000 subject to the Underwriters' over-allotment option),
will be issued in fully registered form and only in denominations of $1,000 or
any integral multiple thereof and will mature on February 15, 2004, unless
earlier redeemed at the option of McKesson.     
   
  The Indenture does not contain any restrictions on the payment of dividends
or the repurchase of securities of McKesson or any financial covenants.     
   
  Interest at the annual rate set forth on the cover page hereof is payable
semiannually on February 15 and August 15, commencing on August 15, 1994, to
holders of record at the close of business on the preceding February 1 and
August 1, respectively, and may, at McKesson's option, be paid by check mailed
to such holders.     
   
  Principal and premium, if any, will be payable, and the Debentures may be
presented for exchange, registration of transfer and substitution, without
service charge, at the office of the Trustee in New York, New York.     
   
  As of March 2, 1994, McKesson owned 11,975,000 shares of Armor All Common
Stock (representing approximately 57% of Armor All's outstanding shares), and a
majority of the members of Armor All's Board of Directors are also officers of
McKesson. As a result, McKesson may be able to control Armor All and, as a
result of such control, may be able to effect certain transactions which could
result in a change in the composition of the Exchange Property.     
   
EXCHANGE RIGHTS     
   
  The Debentures (or portions thereof in integral multiples of $1,000) are
exchangeable, at the option of the holder, for Armor All Common Stock and/or
other Exchange Property, at any time after 60 days following the original
issuance thereof and from time to time prior to maturity or redemption, at a
price (the "Exchange Price") initially equal to $   per share of Armor All
Common Stock (equivalent to an exchange rate of    shares of Armor All Common
Stock per $1,000 principal amount of Debentures). The Exchange Price will be
proportionately adjusted if (1) Armor All effects a stock dividend or stock
split or a combination of outstanding shares of Armor All Common Stock into a
smaller number of shares, or (2) some (but not all) of the shares of Armor All
Common Stock otherwise deliverable upon exchange are sold or exchanged pursuant
to a tender or exchange offer for Armor All Common Stock or are otherwise sold
or transferred in a manner provided in the Indenture. In the event Armor All is
merged or consolidated with or into any     
 
                                       28
<PAGE>
 
   
other entity, or all or substantially all the assets of Armor All are sold or
transferred, and as a result holders of shares of Armor All Common Stock, as
constituted prior to the consummation of the transaction, receive other
securities and/or property, including cash, in exchange for their shares of
Armor All Common Stock, or in the event of a tender or exchange offer for Armor
All Common Stock which results in the sale or exchange of all shares of Armor
All Common Stock previously constituting Exchange Property, McKesson will
execute and deliver a supplemental indenture and a supplement to the Exchange
Agent Agreement as described below under "--Merger or Consolidation of Armor
All" and "--Tender or Exchange Offer." No fractional shares or interests in
Armor All Common Stock or other Exchange Property will be delivered on any
exchange of Debentures, but in lieu thereof a cash adjustment will be paid
based on the Market Price (as defined below under "--McKesson's Cash Option on
Exchange") of the Armor All Common Stock or other Exchange Property.     
   
  Debentures may be exchanged at any time after 60 days following their
original issuance but prior to their maturity or, in the event they are called
for redemption, until the close of business on the date immediately prior to
the date of redemption. In order to exercise the right of exchange, a
Debentureholder must properly complete the Exchange Notice provided on the
Debenture and surrender the Debenture to The First National Bank of Chicago,
who will act as exchange agent for Debentureholders (the "Exchange Agent") on
behalf of McKesson, at the office of the Exchange Agent maintained for such
purpose in New York, New York. If Debentures not called for redemption are
surrendered for exchange during the period from the close of business on a
record date for the payment of interest and prior to the next succeeding
interest payment date, such Debentures must be accompanied by funds equal to
the interest payable on such succeeding interest payment date on the principal
amount so exchanged.     
   
  Upon any such proper surrender of Debentures for exchange, the
Debentureholder will receive the amount and kind of Armor All Common Stock
and/or other Exchange Property deliverable upon such exchange. As described
below under "--McKesson's Cash Option on Exchange," however, McKesson at its
option may pay cash in lieu of delivering the Exchange Property. The
Debentureholder will also receive a check for fractional shares or interests,
if any, in the Exchange Property. If less than the full principal amount of a
Debenture has been surrendered for exchange, the Debentureholder will also
receive a Debenture representing the unexchanged principal amount.     
   
  Delivery of Armor All Common Stock or other Exchange Property may be delayed
at the request of McKesson in order to calculate any necessary adjustments on
the Exchange Property, to obtain any certificate representing securities to be
delivered, to complete any reapportionment of the Exchange Property required by
the Indenture or to comply with any applicable law. If, in the opinion of
counsel to McKesson, securities constituting Exchange Property may not be
delivered in exchange for Debentures without registration under the Securities
Act, McKesson will cause any such required registration as promptly as
practicable, but in the absence of such registration McKesson may deliver cash
in lieu of such securities. Such registration may be required if the securities
constituting Exchange Property have been issued by an entity of which McKesson
is an "affiliate" within the meaning of the federal securities laws, but no
assurances can be given that McKesson will be able to cause such registration.
       
 Deposit of Exchange Property     
   
  Initially, the Exchange Property shall consist solely of shares of Armor All
Common Stock, and prior to and in connection with the original issuance of the
Debentures, McKesson will deposit the number of shares of Armor All Common
Stock deliverable in exchange for the Debentures with the Exchange Agent.
Exchange Property may, as a result of potential extraordinary transactions
involving Armor All Common Stock, subsequently include cash or property other
than or in addition to Armor All Common Stock. See "--Additions to Exchange
Property," "--Merger or Consolidation of Armor All," and "--Tender or Exchange
Offer." In any such case, McKesson will deposit with the Exchange Agent any
cash and other property which may become deliverable as Exchange Property in
exchange for the Debentures. McKesson will not be permitted to pledge,
mortgage, hypothecate or grant a security interest in, or permit any mortgage,
    
                                       29
<PAGE>
 
   
pledge, security interest or other lien upon, the Armor All Common Stock or
other Exchange Property so deposited. However, McKesson will be entitled to
vote the shares of Armor All Common Stock and any other voting securities which
may constitute Exchange Property so deposited.     
   
  The right of a Debentureholder to exchange Debentures for Armor All Common
Stock or other Exchange Property could be adversely affected in the event of
the bankruptcy, insolvency or liquidation of McKesson. In such event, the Armor
All Common Stock or other Exchange Property could be assets of McKesson subject
to the claims of its general creditors.     
   
  To the extent that Debentures are redeemed prior to exchange, McKesson will
be entitled to receive from the Exchange Agent such number of shares of Armor
All Common Stock and such other Exchange Property, if any, held by the Exchange
Agent for exchange as exceeds the number of shares of Armor All Common Stock or
other Exchange Property required to be held by the Exchange Agent for the
exchange of all Debentures remaining then outstanding. The deposit arrangements
with the Exchange Agent will terminate at such time as the right to exchange
Debentures shall have expired pursuant to the Indenture.     
   
  Subject to the Repurchase Rights described below, McKesson will be entitled
to withdraw Armor All Common Stock or other Exchange Property deposited with
the Exchange Agent. However, no such withdrawal shall in any way affect
McKesson's obligation to deliver the precise kind and amount of Exchange
Property to which a Debentureholder surrendering Debentures for exchange is
entitled at the time of surrender (or, at McKesson's option, the cash value of
that precise kind and amount of Exchange Property, as described below under "--
McKesson's Cash Option on Exchange").     
   
 McKesson's Cash Option on Exchange     
   
  In lieu of delivering Exchange Property in exchange for any Debentures,
McKesson may pay to the holder surrendering such Debentures an amount in cash
equal to the market price of the Exchange Property for which such Debentures
are exchangeable (the "Market Price"), based on (1) in the case of Armor All
Common Stock or other Exchange Property which consists of publicly traded
securities, the average closing market price (or average bid and asked prices,
if closing prices are not available) for the five consecutive trading days
immediately preceding the date of receipt by the Exchange Agent of the notice
of exchange relating to such Debentures (or, if such date is not a business
day, on the business day next preceding such date), and (2) in the case of
Exchange Property which does not consist of publicly traded securities, the
market value of such property on the date of receipt by the Exchange Agent of
the notice of exchange relating to such Debentures as determined by an
investment banking firm selected by the Exchange Agent. Before directing the
Exchange Agent to make any such cash payment, McKesson will deposit with the
Exchange Agent the cash so payable.     
   
 Additions to Exchange Property     
   
  McKesson will be entitled to receive all ordinary cash dividends paid and
interest earned on the shares of Armor All Common Stock or other Exchange
Property deposited with the Exchange Agent. All other distributions (including
extraordinary cash dividends), if any, on deposited shares of Armor All Common
Stock or other Exchange Property shall (after any sale of such distributed
property or any provision for taxes, as described below) become additional
Exchange Property. The additional Exchange Property will be apportioned pro
rata among the deposited shares of Armor All Common Stock (or, if there shall
be no such shares, among such other Exchange Property as shall have replaced
such shares).     
   
  If there is a taxable distribution on Exchange Property of any securities,
options, warrants or similar rights or other noncash items of property,
McKesson will instruct the Exchange Agent to sell all such distributed property
for cash in such manner as McKesson shall instruct, and the cash proceeds of
such property after payment of taxes thereon will be Exchange Property. If
extraordinary cash dividends are paid on securities constituting Exchange
Property pursuant to a plan of liquidation, partial liquidation,

recapitalization or restructuring, or if securities constituting Exchange
Property are converted into cash pursuant to a merger or tender offer, then,
after payment of any taxes thereon, the remainder will be Exchange Property.
       
  If there is a nontaxable distribution on Exchange Property of any securities
or other noncash items of property (other than options, warrants or similar
rights as described in the following paragraph), McKesson may, at its option,
cause the sale of some or all of such property (which may be a taxable event),
and the cash proceeds and/or the remainder of such property after payment of
any taxes thereon will be Exchange Property.     
   
  If there is a nontaxable distribution on Exchange Property of any options,
warrants or similar rights, McKesson may, at its option, (1) cause the sale of
such options, warrants or similar rights (which may be a taxable event), and
the cash proceeds, after payment of any taxes thereon, will be Exchange
Property; (2) to the extent there is sufficient cash among the Exchange
Property or to the extent McKesson may cause the sale of Armor All Common Stock
or other Exchange Property to provide sufficient cash, after provision for
taxes, among the Exchange Property, cause the exercise of such options,
warrants or similar rights and thereafter, either (a) retain the securities
received upon such exercise as Exchange Property, (b) cause some or all of such
securities to be sold (which may be a taxable event), in which case the cash
proceeds and the remainder of such property, if any, after payment of any taxes
thereon, will be Exchange Property, or (c) cause the pro rata distribution of
such securities to Debentureholders; (3) retain such options, warrants or
similar rights as Exchange Property, provided that such options, warrants or
similar rights shall not be allowed to expire unexercised so long as they are
in the money and if otherwise feasible; or (4) cause the pro rata distribution
of such options, warrants or similar rights to Debentureholders. Because any
subsequent distribution to Debentureholders of securities, options, warrants or
similar rights or other noncash items of property received with respect to
Exchange Property may give rise to tax liability for McKesson, McKesson may be
more likely to elect to cause the sale of such items (or, in the case of
options, warrants or similar rights, to cause the sale of the securities
received upon the exercise of such items) and to cause the cash proceeds (after
provision for taxes) to be treated as Exchange Property, in lieu of causing the
pro rata distribution of such items to the Debentureholders.     
   
  Upon the happening of any of the foregoing events with respect to the Armor
All Common Stock or other Exchange Property which is taxable or treated as
being taxable to McKesson or the Exchange Agent, the Exchange Agent will
deliver cash which it holds for exchange (including cash received as a result
of such event) to McKesson or to itself for payment of the taxes arising from
such transaction. If the cash held for exchange is insufficient to pay such
taxes, the Exchange Agent will sell such of the shares of Armor All Common
Stock or other Exchange Property as may be necessary to pay the amount of the
insufficiency and any taxes payable by McKesson or the Exchange Agent arising
from such sale. Any proceeds from such sale which remain after the above tax
payments are made will be Exchange Property.     
   
 Merger or Consolidation of Armor All     
   
  In the case of any merger or consolidation of Armor All with or into any
other entity which results in shares of Armor All Common Stock, as constituted
prior to the consummation of such transaction, being converted into other
securities and/or property, including cash, or any sale or transfer of all or
substantially all the assets of Armor All (if in connection with such sale or
transfer holders of Armor All Common Stock receive other securities and/or
property, including cash, in exchange for their shares of Armor All Common
Stock), McKesson will execute and deliver to the Trustee a supplemental
indenture, and to the Exchange Agent a supplement to the Exchange Agent
Agreement, each providing that the holder of any Debenture surrendered for
exchange thereafter will, subject to provision for taxes, be entitled to
receive, in addition to other Exchange Property, if any, the kind and amount of
securities and/or property receivable in connection with such transaction by a
holder of the number of shares of Armor All Common Stock for which such
Debenture might have been exchanged immediately prior to such transaction.     
 
                                       31
<PAGE>
 
   
 Tender or Exchange Offer     
   
  In the event of a tender offer or exchange offer for any class of securities
included within the Exchange Property (1) if McKesson owns other securities of
such class which are not Exchange Property, McKesson will cause the Exchange
Agent to tender such securities of such class in the same proportion that
McKesson tenders its securities in such class which are not Exchange Property,
and (2) if the only securities of such class owned by McKesson are Exchange
Property, McKesson may, at its option and in its sole discretion, elect to
cause the Exchange Agent to tender all or any portion or none of such class of
security included within the Exchange Property. If, however, the tender or
exchange offer for securities included within the Exchange Property is made by
McKesson or any affiliate of McKesson, McKesson will not cause the Exchange
Agent to tender any such securities unless a majority of such class of
securities that are held by persons other than McKesson or any affiliate of
McKesson have been tendered and not withdrawn pursuant to such tender or
exchange offer as of immediately prior to the expiration of such offer. The
proceeds, after provision for taxes, of the sale of any such Exchange Property
pursuant to any such tender or exchange offer will be held by the Exchange
Agent for the benefit of Debentureholders as provided in the Indenture. A
tender or exchange offer, whether made by McKesson, any affiliate of McKesson
or a third party, may result in shares of Armor All Common Stock or other
Exchange Property being replaced by cash or other property (which may or may
not be publicly traded equity securities) and would not trigger the Repurchase
Rights described below under "--Repurchase Rights." As a result of the tender
or exchange of Armor All Common Stock or other Exchange Property,
Debentureholders will not participate in any subsequent appreciation or
depreciation in the market price of the tendered securities. If any tender
offer or exchange offer results in there being no shares of Armor All Common
Stock among the Exchange Property, McKesson will execute and deliver to the
Trustee a supplemental indenture, and to the Exchange Agent a supplement to the
Exchange Agent Agreement, each providing that the holder of any Debenture
surrendered for exchange thereafter will, subject to provision for taxes, be
entitled to receive, in addition to other Exchange Property, if any, the kind
and amount of securities and/or property receivable upon or in connection with
such tender or exchange offer by a holder of the number of shares of Armor All
Common Stock for which such Debenture might have been exchanged immediately
prior to such transaction.     
   
 Certain Tax Withholding, Notices and Investment of Exchange Property     
   
  From time to time, McKesson may require the Exchange Agent to segregate such
Exchange Property as McKesson determines may be necessary for McKesson or the
Exchange Agent to pay taxes with respect to the transactions or events
described above, subject to the determination of taxability (and any expenses
incurred in determining taxability), and such property (or any portion thereof)
will be deliverable to holders of Debentures only after determination that such
withholding is not necessary for the payment of such taxes and after deducting
the expenses incurred in connection with such determination.     
   
  McKesson is required to notify Debentureholders of certain dividends or other
distributions on the Armor All Common Stock or other Exchange Property
deliverable upon exchange of Debentures, the granting of subscription rights,
options, warrants or other similar rights to holders of Armor All Common Stock,
any reclassification of Armor All Common Stock (other than a subdivision or
combination of outstanding shares of Armor All Common Stock), certain mergers
involving Armor All, the sale of all or substantially all of the assets of
Armor All, and the dissolution, liquidation or winding up of Armor All.     
   
  Any cash held by the Exchange Agent that is deliverable as Exchange Property
upon exchange of Debentures will be invested by the Exchange Agent at the
direction of McKesson in U.S. Government Obligations with maturity dates of
twelve months or less. Any interest or gain on such investments will be for the
benefit of McKesson, and McKesson will be responsible for any losses on such
investments. As used in the Indenture, the term "U.S. Government Obligations"
means direct non-callable obligations of, or non-callable obligations the
payment of principal of and interest on which is guaranteed by, the United
States of America, or to the payment of which obligations or guarantees the
full faith and credit of the United States of America is pledged, or beneficial
interests in a trust the corpus of which consists exclusively of money or such
obligations or a combination thereof.

REPURCHASE RIGHTS
 
  The Exchange Agent will act as agent for McKesson in connection with
McKesson's exchange obligations under the Indenture and will not act as escrow
agent for the benefit of holders of Debentures. Accordingly, McKesson may at
any time obtain from the Exchange Agent or otherwise authorize or direct the
Exchange Agent to release all or a part of the Armor All Common Stock or other
Exchange Property. In the event that McKesson obtains or otherwise releases any
Armor All Common Stock or other Exchange Property, other than Exchange Property
in excess of that which would be deliverable upon exchange of all Debentures
then outstanding, each Debentureholder will have the right (a "Repurchase
Right"), at such holder's option, to require McKesson to repurchase all of such
holder's Debentures, or a portion thereof which is $1,000 or any integral
multiple thereof, in the manner and at the price described below.
   
  Promptly (and in any event within 10 days) after McKesson has obtained or
released any Exchange Property other than Exchange Property in excess of that
which would be deliverable upon exchange of all then outstanding Debentures,
the Exchange Agent will mail to all Debentureholders of record a notice thereof
and the Repurchase Right arising as a result thereof (a "Repurchase Notice").
To exercise the Repurchase Right, a Debentureholder must deliver on or before
the 20th business day after the date of the Repurchase Notice written notice to
the Exchange Agent of the holder's exercise of such right, together with the
Debentures with respect to which such right is being exercised, duly endorsed
for transfer.     
   
  Promptly after the expiration of the period in which a Debentureholder may
exercise the Repurchase Right (the "Repurchase Date"), McKesson will be
required to repurchase all Debentures in respect of which the Repurchase Right
has been exercised at the following repurchase price: (i) if the date on which
McKesson first obtains or releases Exchange Property other than Exchange
Property in excess of that which would be deliverable upon exchange of all then
outstanding Debentures (the "Triggering Date") is before February 16, 1999, the
product of (1) 120% and (2) the greater of the principal amount at maturity of
such Debentures (plus accrued and unpaid interest, if any, to the Repurchase
Date) and the Market Price of the Exchange Property deliverable in exchange for
such Debentures on the Triggering Date (or if such date is not a business day,
on the next succeeding business day); and (ii) if the Triggering Date occurs on
or after February 16, 1999, the greater of (1) the redemption price as
specified under "Redemption Provisions" on the Triggering Date and (2) the
Market Price of the Exchange Property deliverable in exchange for such
Debentures on the Triggering Date (or if such date is not a business day, on
the next succeeding business day).     
   
  The obligation of McKesson to deliver Exchange Property (or cash in lieu
thereof) in exchange for Debentures shall survive and continue to apply in full
force and effect following and notwithstanding the occurrence of any event
triggering a Repurchase Right. Failure by McKesson to exchange Debentures in
accordance with the Indenture or to repurchase Debentures upon exercise of a
Repurchase Right will constitute an Event of Default with respect to the
Debentures, and holders of Debentures will have the remedies provided for in
the Indenture, including acceleration of the indebtedness evidenced by the
Debentures, in the event of any such failure. See "Events of Default and
Remedies."     
 
  The exchange obligations of McKesson may not be assigned or otherwise
transferred by McKesson except in accordance with a transfer of the
indebtedness evidenced by the Debentures in the manner permitted by the
Indenture.
   
  If an offer is made to repurchase Debentures in connection with a Repurchase
Right, McKesson will comply with all tender offer rules, including but not
limited to Sections 13(e), 14(d) and 14(e) under the Exchange Act and Rules
13e-1, 13e-4 and 14e-1 thereunder, to the extent applicable to such offer
(including any applicable withdrawal rights).     
 
REDEMPTION PROVISIONS
 
  The Debentures will not be redeemable prior to February 16, 1999. At any time
on or after that date, the Debentures may be redeemed at the option of
McKesson, in whole or from time to time in part, on not less than 30 nor more
than 60 days' notice by mail, at the following redemption prices (expressed as
percentages of the principal amount) if redeemed during the 12-month period
beginning February 15 of the following years:

and 100% at February 15, 2004, in each case together with accrued interest to
the redemption date; provided, however, that installments of interest on
Debentures whose stated maturity is on or prior to the redemption date shall be
payable to the holders of such Debentures, registered as such at the close of
business on the relevant record dates. If fewer than all of the Debentures are
to be redeemed, the Trustee will select the Debentures to be redeemed by lot
or, in its discretion, on a pro rata basis. If any Debenture is to be redeemed
in part only, a new Debenture or Debentures in principal amount equal to the
unredeemed principal portion thereof will be issued. There is no sinking fund
applicable to the Debentures.
 
CONSOLIDATION, MERGER AND SALE OF ASSETS
 
  McKesson may merge or consolidate into or with any other corporation or sell,
convey or lease all or substantially all of its property to any other
corporation, provided that (i) the corporation formed by such consolidation or
merger or which has acquired or leased such property is organized under the
laws of any State of the United States or the District of Columbia and such
corporation expressly assumes all of the covenants and conditions of the
Indenture by executing and delivering a supplemental indenture to the Trustee
providing for the applicable exchange rights set forth in the Indenture, and
(ii) at the time of such transaction and immediately after giving effect
thereto, no Event of Default shall have occurred and be continuing.
 
SUBORDINATION OF DEBENTURES
 
  The indebtedness evidenced by the Debentures is subordinate to the prior
payment in full of all Senior Indebtedness (as defined). During the continuance
beyond any applicable grace period of any default in the payment of principal,
premium, interest or any other payment due on any Senior Indebtedness, no
payment of principal of, or premium, if any, or interest on the Debentures
shall be made by McKesson. In addition, upon any distribution of assets of
McKesson upon any dissolution, winding up, liquidation or reorganization, the
payment of the principal of, or premium, if any, and interest on the Debentures
is to be subordinated to the extent provided in the Indenture in right of
payment to the prior payment in full of all Senior Indebtedness. By reason of
the subordination, in the event of McKesson's dissolution, holders of Senior
Indebtedness may receive more, ratably, and holders of the Debentures may
receive less, ratably, than the other creditors of McKesson. Such subordination
will not prevent the occurrence of any Event of Default under the Indenture.
 
  Subject to the qualifications described below, the term "Senior Indebtedness"
means the principal of, premium, if any, interest on, and any other payment due
pursuant to any of the following whether outstanding on the date of the
Indenture or thereafter incurred or created:
 
    (a) All indebtedness of McKesson for money borrowed (including any
  indebtedness secured by a mortgage or other lien which is (i) given to
  secure all or part of the purchase price of property subject thereto,
  whether given to the vendor of such property or to another, or (ii)
  existing on property at the time of acquisition thereof);
 
    (b) All indebtedness of McKesson evidenced by notes, debentures, bonds or
  similar instruments (excluding any such indebtedness for trade payables or
  constituting the deferred purchase price of assets or services incurred in
  the ordinary course of business) and all indebtedness of McKesson
  consisting of reimbursement obligations due and owing with respect to
  letters of credit;
 
                                       34
<PAGE>
 
    (c) All lease obligations of McKesson which are capitalized on the books
  of McKesson in accordance with generally accepted accounting principles;
 
    (d) All indebtedness consisting of commitment or standby fees due and
  payable to lending institutions with respect to credit facilities available
  to McKesson;
 
    (e) All indebtedness consisting of obligations of McKesson due and
  payable under interest rate and currency swaps, floors, caps or other
  similar arrangements intended to fix interest rate obligations;
 
    (f) All indebtedness of others of the kinds described in any of the
  preceding clauses (a), (b), (d), or (e) and all lease obligations of the
  kind described in the preceding clause (c) assumed by or guaranteed in any
  manner by McKesson or in effect guaranteed by McKesson through an agreement
  to purchase, contingent or otherwise; and
 
    (g) All renewals, extensions, refundings, deferrals, amendments,
  modifications or supplements of indebtedness of the kinds described in any
  of the preceding clauses (a), (b), (d), (e) or (f) and all renewals or
  extensions of lease obligations of the kinds described in any of the
  preceding clauses (c) or (f);
 
unless in the case of any particular indebtedness, lease, renewal, extension,
refunding, amendment, modification or supplement, the instrument, lease or
other document creating or evidencing the same or the assumption or guarantee
of the same expressly provides that such indebtedness, lease, renewal,
extension, refunding, amendment, modification or supplement is not superior in
right of payment to the Debentures. Notwithstanding the foregoing, Senior
Indebtedness shall not include any indebtedness or lease obligations of any
kind of McKesson to any subsidiary of McKesson, a majority of the voting stock
of which is owned, directly or indirectly, by McKesson.
 
  As of January 31, 1994, McKesson had outstanding Senior Indebtedness of
approximately $47 million. The amount of Senior Indebtedness may change in the
future. The Indenture contains no limitation on the incurrence of additional
Senior Indebtedness.
 
  Because substantially all of the assets of McKesson are owned by its
subsidiaries, McKesson's rights and the rights of its creditors, including
Debentureholders, to participate in the assets of any McKesson subsidiary upon
the subsidiary's liquidation, recapitalization or otherwise will be effectively
subordinated to the prior claims of the subsidiary's creditors (including trade
creditors), except to the extent that McKesson may itself be a creditor with
recognized claims against the subsidiary. As of January 31, 1994, McKesson's
subsidiaries had total interest-bearing indebtedness (which does not include
trade debt) of approximately $537 million.
 
EVENTS OF DEFAULT AND REMEDIES
 
  An Event of Default is defined in the Indenture as being default in payment
of the principal of or premium, if any, on the Debentures; default for 30 days
in payment of any installment of interest on the Debentures; failure by
McKesson to deliver Armor All Common Stock or other Exchange Property (or cash
in lieu thereof) upon exchange of the Debentures; failure by McKesson to
repurchase Debentures upon the exercise of a Repurchase Right; default by
McKesson in any material respect for 60 days after notice in the observance or
performance of any other covenants contained in the Indenture for the benefit
of holders of the Debentures; or certain events involving bankruptcy,
insolvency or reorganization of McKesson or, under certain circumstances,
McKesson-Maryland. The Indenture provides that the Trustee may withhold notice
to the holders of Debentures of any default (except in payment of principal, or
premium, if any, or interest with respect to the Debentures) if the Trustee
considers it in the interest of the holders of the Debentures to do so.
 
  The Indenture provides that if any Event of Default shall have occurred and
be continuing, the Trustee or the holders of not less than 25% in principal
amount of the Debentures then outstanding may declare the principal of the
Debentures to be due and payable immediately, but if McKesson shall cure all
defaults (except
 
                                       35
<PAGE>
 
the nonpayment of interest on, premium, if any, and principal of any Debentures
which shall have become due by acceleration) and certain other conditions are
met, such declaration may be cancelled and past defaults may be waived by the
holders of a majority in principal amount of Debentures then outstanding.
 
  The holders of a majority in principal amount of the Debentures then
outstanding shall have the right to direct the time, method and place of
conducting any proceedings for any remedy available to the Trustee, subject to
certain limitations specified in the Indenture.
 
MODIFICATIONS OF THE INDENTURE
 
  The Indenture contains provisions permitting McKesson and the Trustee, with
the consent of the holders of not less than a majority in principal amount of
the Debentures at the time outstanding, to modify the Indenture or any
supplemental indenture or the rights of the holders of the Debentures, except
that no such modification shall (i) extend the fixed maturity of any Debenture,
reduce the rate or extend the time or payment of interest thereon, reduce the
principal amount thereof or premium, if any, thereon, impair or affect the
right of a holder to institute suit for the payment thereof, change the
currency in which the Debentures are payable, modify the subordination
provisions of the Indenture in a manner adverse to the holders of the
Debentures, or impair the right of holders to exchange the Debentures for
Exchange Property or to cause the repurchase of the Debentures, subject to the
terms set forth in the Indenture, without the consent of the holder of each
Debenture so affected, or (ii) reduce the aforesaid percentage of Debentures,
without the consent of the holders of all of the Debentures then outstanding.
 
SATISFACTION AND DISCHARGE
 
  McKesson may discharge its obligations under the Indenture when either the
Debentures have been delivered to the Trustee for cancellation or if not so
delivered (a) have become due and payable, or (b) will become due and payable
at their scheduled maturity within one year, or (c) are to be called for
redemption within one year, or (d) are delivered to the Trustee for exchange or
repurchase, and in each such case, McKesson has deposited with the Trustee an
amount sufficient to discharge the entire indebtedness on such Debentures on
the date of their scheduled maturity or the scheduled date of redemption.
 
GOVERNING LAW
 
  The Indenture and the Debentures will be governed by and construed in
accordance with the laws of the State of New York, without giving effect to
such State's conflict of laws principles.
 
CONCERNING THE TRUSTEE
 
  The First National Bank of Chicago is the Trustee under the Indenture and has
been appointed by McKesson as the paying agent, registrar and custodian with
regard to the Debentures. The First Chicago Trust Company of New York, an
affiliate of the Trustee, is the transfer agent of McKesson's Common Stock and
of the Armor All Common Stock. The Trustee and its affiliates provide and may
continue to provide banking services to McKesson and/or Armor All in the
ordinary course of their business.
 
                     CERTAIN UNITED STATES TAX CONSEQUENCES
 
  The following summary is a general discussion of certain United States
federal income tax consequences of acquiring, holding and disposing of the
Debentures, including the exchange of the Debentures for Armor All Common
Stock, and of acquiring, holding and disposing of Armor All Common Stock
received in such exchange. The summary is based upon laws, regulations, rulings
and decisions now in effect or about to come into effect, all of which are
subject to change. This summary does not discuss all aspects of federal income
taxation that may be relevant to a particular investor in light of the
investor's personal investment
 
                                       36
<PAGE>
 
circumstances and does not discuss any aspects of state, local or foreign tax
laws that may be applicable to the Debentures, to Armor All Common Stock or to
the holders thereof. This discussion is limited to persons who hold Debentures
and Armor All Common Stock as "capital assets" (generally, property held for
investment) within the meaning of section 1221 of the Internal Revenue Code of
1986, as amended (the "Code"), and does not cover special rules applicable to
taxpayers who may fall into special classes, such as financial institutions,
insurance companies, mutual funds, S corporations, trusts and exempt
institutions. This discussion also does not deal with circumstances where all
or a portion of the Exchange Property is other than Armor All Common Stock.
Accordingly, prospective purchasers should consult their own tax advisors with
respect to the application of federal, state, local and foreign tax laws to
them in light of their particular circumstances concerning the matters
discussed below.
 
INTEREST AND ORIGINAL ISSUE DISCOUNT
 
 Stated Interest
 
  Stated interest on the Debentures will be includable in and taxable as
ordinary income in accordance with the holder's method of accounting.
 
 Original Issue Discount
 
  On February 2, 1994, the U.S. Treasury Department promulgated final
regulations which provide, among other things, that the exchange right
contained in a Debenture (i.e., the right to exchange the Debenture for Armor
All Common Stock) is to be ignored for purposes of applying the original issue
discount provisions of the Code. While those final regulations are generally
effective for obligations issued on or after April 4, 1994, taxpayers may rely
on the final regulations, other than portions dealing with an election not here
relevant, for obligations issued after December 21, 1992; McKesson intends to
rely on these recently promulgated final regulations with respect to the
Debentures.
 
  Accordingly, the Debentures will be viewed as issued with original issue
discount only if their issue price (in general, the first price at which a
substantial amount of Debentures is sold for cash) exceeds their stated
redemption price at maturity (in this case the principal amount of $1,000) by
more than a de minimis amount (generally, .0025 multiplied by the Debentures'
stated redemption price at maturity (here $1,000) multiplied by the number of
complete years to maturity from the issue date). As it is expected that the
issue price of the Debentures will be $1,000, it is not expected that the
Debentures will be issued with original issue discount.
 
  If the Debentures were issued with original issue discount, then a holder of
a Debenture generally would be required to include in gross income
(irrespective of such holder's method of accounting) a portion of the original
issue discount for each year during which the Debenture is held, even though
the holder may not have received payment in respect of such income. The amount
of any original issue discount included in income for each year would be
calculated under a constant yield to maturity formula that would result in the
inclusion of less original issue discount in the early years of the term of the
Debenture and more original issue discount in the later years.
 
TAX BASIS OF DEBENTURES
 
  The federal income tax basis of a Debenture will be equal to the full amount
paid for the Debenture, increased, were the Debentures issued with original
issue discount, by any original issue discount included in the holder's income.
 
DISPOSITION OF DEBENTURES
 
  Generally the redemption by McKesson (including the exercise of its option to
pay cash in lieu of Armor All Common Stock or other Exchange Property to an
exchanging Debentureholder) or the sale of the
 
                                       37
<PAGE>
 
Debentures will result in taxable gain or loss equal to the difference between
the amount of cash and fair market value of other property received and the
holder's tax basis in the Debentures. Such gain or loss will be capital gain or
loss and will be long-term gain or loss if the holding period exceeds one year.
To the extent that the amount received is attributable to accrued interest,
however, that amount will be taxed as ordinary income.
 
EXCHANGE OF DEBENTURES FOR ARMOR ALL COMMON STOCK
 
  If a Debentureholder exercises the right to exchange a Debenture for Armor
All Common Stock, such exchange will be treated as a taxable disposition, and
the holder will be required to recognize taxable gain (or loss) to the extent
that the fair market value of the Armor All Common Stock received in such
exchange exceeds (or is less than) the holder's adjusted tax basis in the
Debenture immediately prior to such exchange. Any gain or loss on the exchange
generally will be long-term capital gain or loss if the Debenture has been held
for more than one year. The holder's tax basis for the Armor All Common Stock
would equal its fair market value at the time of the exchange, and the holder's
holding period for the Armor All Common Stock would not include any portion of
the holding period for the exchanged Debenture.
 
ADJUSTMENT OF EXCHANGE RATE AND MODIFICATION OF EXCHANGE PROPERTY
   
  Holders of Debentures may be deemed to have received constructive
distributions where the exchange rate is adjusted to reflect property
distributions with respect to Armor All Common Stock into which such Debentures
are exchangeable. Adjustments to the exchange rate made pursuant to a bona fide
reasonable adjustment formula which has the effect of preventing the dilution
of the interest of the holders of the Debentures, however, will generally not
be considered to result in a constructive distribution of Armor All Common
Stock. Certain adjustments provided in the Debentures may not qualify as being
pursuant to a bona fide reasonable adjustment formula. If such adjustments were
made, the holders of Debentures could be deemed to have received constructive
distributions taxable as dividends to the extent of Armor All earnings and
profits. See "--Distributions on Armor All Common Stock." In addition,
distributions with respect to Exchange Property of any securities, options,
warrants, similar rights or other noncash items of property could be viewed as
equivalent to exchange rate adjustments giving rise to constructive
distributions to holders of Debentures. Further, under proposed U.S. Treasury
Department regulations, some of the possible changes in the Exchange Property
could be deemed a "significant modification" of the Debentures, which would be
treated as a taxable exchange of the original Debentures for modified debt
instruments, giving rise to gain or loss in the hands of a Debentureholder
equal to the difference between the fair market value of the modified debt
instruments and such holder's adjusted basis in the original Debentures.     
 
DISTRIBUTIONS ON ARMOR ALL COMMON STOCK
 
  Distributions with respect to shares of Armor All Common Stock that are
received in exchange for Debentures will be treated as dividends for federal
income tax purposes and will be taxed as ordinary income to the extent of Armor
All's earnings and profits for such purposes. Certain corporations may qualify
for a 70% dividends received deduction (80% for certain corporate stockholders
owning at least 20%, by vote and value, of Armor All's stock) if various
conditions are met.
 
  Distributions will constitute dividends taxable as ordinary income to the
extent Armor All has either (a) current earnings and profits determined at the
end of the taxable year in which the distribution is made or (b) accumulated
earnings or profits determined at the time the distribution is made. To the
extent that the entire distribution is greater than the amount of earnings and
profits determined above, the excess will be treated as a nontaxable return of
capital which will reduce the recipient's basis for the Armor All Common Stock.
To the extent that a recipient receives aggregate distributions that are not
out of current or accumulated earnings and profits and such distributions
exceed the tax basis of the Armor All Common Stock, the excess will be taxed as
a gain from the sale or exchange of the Armor All Common Stock. See "--
Dispositions of Armor All Common Stock."
 
                                       38
<PAGE>
 
  To be entitled to the dividends received deduction, stockholders taxed as
regular corporations must, among other requirements, hold the Armor All Common
Stock for a period of more than 45 days, not counting days on which the
stockholder's risk of loss is diminished, for example, by a short sale. One
item of tax preference for corporations is 75% of the excess of adjusted
current earnings over alternative minimum taxable income (determined without
regard to this preference or any alternative minimum tax net operating loss
carryovers). Thus, a corporation's alternative minimum tax base would generally
be increased by 75% of the dividends received deduction, although special rules
may apply to dividends eligible for an 80% dividends received deduction.
 
  To the extent a corporation incurs indebtedness directly attributable to
investment in portfolio stock in another corporation (which would include Armor
All Common Stock received upon exchange of the Debentures), the dividends
received deduction will be reduced by a percentage equal, in general, to the
amount of such indebtedness divided by the total adjusted tax basis in the
investment. In addition, the dividends received deduction cannot exceed 70% of
taxable income with certain adjustments (80% in the case of dividends
qualifying for the 80% dividends received deduction). Finally, corporate
stockholders may be required in certain circumstances to reduce the tax basis
of their shares of Armor All Common Stock to reflect the dividends received
deduction allowed with respect to certain "extraordinary dividends," if any,
paid on the Armor All Common Stock.
 
DISPOSITIONS OF ARMOR ALL COMMON STOCK
 
  Generally, any sale or other disposition of Armor All Common Stock will be a
taxable event and will result in capital gain or loss if the Armor All Common
Stock is held as a capital asset. The amount of such gain or loss will
generally be the difference between the federal income tax basis of the Armor
All Common Stock on the date of the sale or other disposition and the cash and
fair market value of property received. Such gain or loss will be long-term
gain or loss if the Armor All Common Stock is held for more than one year.
 
BACKUP WITHHOLDING
 
  Under the backup withholding provisions of the Code and applicable U.S.
Treasury Department regulations, a holder of Debentures or Armor All Common
Stock may be subject to backup withholding at the rate of 31% with respect to
interest on and any original issue discount with respect to Debentures,
dividends on Armor All Common Stock and the gross proceeds of a sale, exchange,
retirement or redemption of Debentures or Armor All Common Stock. However,
backup withholding generally will not be required if such holder (a) is a
corporation or comes within certain other exempt categories and when required
demonstrates this fact or (b) provides a taxpayer identification number,
certifies as to no loss of exemption from backup withholding, and otherwise
complies with applicable requirements of the backup withholding rules. The
amount of any backup withholding from a payment to a holder will be allowed as
a credit against the holder's federal income tax liability and may entitle such
holder to a refund, provided that the required information is furnished to the
Internal Revenue Service ("IRS").
 
  McKesson or Armor All will cause to be reported to the holders of Debentures
or Armor All Common Stock and the IRS for each calendar year the amount of
interest or dividends paid and original issue discount accrued during such
year, if any, and the amount of tax withheld, if any, with respect to the same.
 
FOREIGN HOLDERS
 
  Interest and original issue discount, if any, on the Debentures held by
nonresident alien individuals or foreign corporations will generally be exempt
from United States federal income tax. To obtain such exemption, the Code
requires the beneficial owner to submit a statement that such owner is not a
United States person, which statement must be filed with the person who would
otherwise be responsible for withholding such tax. Temporary regulations issued
by the U.S. Treasury Department require that statement
 
                                       39
<PAGE>
 
to be signed by the beneficial owner under penalties of perjury and to provide
such owner's address. Interest and original issue discount, if any, on the
Debentures may be subject to United States federal income tax (and branch
profits tax for foreign corporate holders) if they are effectively connected
with the conduct of a trade or business within the United States. There are
also special rules for controlled foreign corporations, certain other types of
foreign stockholders and foreign partnerships, estates and trusts. In general,
dividends paid on shares of Armor All Common Stock held by a nonresident alien
individual or foreign corporation will be subject to withholding tax at a rate
of 30% but will not be subject to backup withholding. The withholding rate may
be lower under an applicable tax treaty. Prospective nonresident purchasers
should consult their tax advisors as to the scope of and procedural
requirements under any such treaties and with regard to the exemption from
United States federal income tax for interest and original issue discount, if
any, on the Debentures and the special backup withholding rules and provisions
regarding gain from the sale, exchange, redemption or other disposition of
Debentures or Armor All Common Stock applicable to such purchasers.

Underwriters in Article III hereof.  The Firm Debentures and the Additional
Debentures are hereinafter collectively referred to herein as the "Debentures".
The Debentures are to be issued pursuant to the provisions of an Indenture dated
as of _________________, 1994 (the "Indenture") between the Company and The

     order suspending the effectiveness of the Registration Statement is in
     effect, and no proceedings for such purpose are pending before or
     threatened by the Commission.

     and the applicable rules and regulations, and none of such documents

     any provision of applicable law or the certificate of incorporation or
     bylaws of Armor All, or any material agreement or other material instrument
     binding upon Armor All or any subsidiary of Armor All or any judgment,
     order or decree of any governmental body, agency or court having
     jurisdiction over Armor All or any subsidiary of Armor All, and no consent,

     the Armor All Shares.

          (j)  There has not occurred any material adverse change, or any
     development involving a prospective material adverse change, in the

     Prospectus.

          (k)  There are no legal or governmental proceedings pending or, to the

     in the Registration Statement or the Prospectus and are not so described,
     or any statutes, regulations, contracts or other documents that are

     or to be filed as exhibits to the Registration Statement that are not
     described or filed as required.

          (l)  Each of Armor All and Armor All Products Canada has all necessary
     consents, authorizations, approvals, orders, certificates and permits of

     regulatory organizations and all courts and other tribunals, to own, lease,
     license and use their respective properties and assets and to conduct their
     respective businesses in the manner described in the Prospectus, except to
     the extent that the failure to obtain or file such would not have a
     material adverse effect on Armor All and its subsidiaries, taken as a
     whole.

          (m)  Each preliminary prospectus filed as part of the registration
     statement as originally filed or as part of any amendment thereto, or filed
     pursuant to Rule 424 under the Securities Act, complied when so filed in

     mental Laws to conduct their respective businesses, and (iii) are in

     to receive required permits, licenses or other approvals or failure to
     comply with the terms and conditions of such permits, licenses or approvals
     would not, singly or in the aggregate, have a material adverse effect on
     Armor All and its subsidiaries, taken as a whole.

          (q)  Each of Armor All and its subsidiaries owns or possesses adequate
     and sufficient licenses or other rights to use all patents, copyrights,
     trademarks, service marks, trade names, technology and know-how necessary
     (in any material respect) to conduct their respective businesses in the

             (xii) to the knowledge of such counsel, there are no legal or
          governmental proceedings pending or threatened which are required to
          be disclosed in the Registration Statement, other than those disclosed
          therein;

            (xiii) the statements (1) in the Prospectus under the caption
          "Certain Relationships and Transactions" and (2) in the Registration
          Statement in Item 15 fairly summarize in all material respects the
          material terms of such provisions or agreements;

             (xiv) the Debentures and the Indenture conform in all material
          respects to the descriptions thereof contained in the Registration
          Statement and the Prospectus;

              (xv) the Company is not an "investment company" or an entity
          "controlled" by an "investment company", as such terms are defined in
          the Investment Company Act of 1940, as amended;

             (xvi) the Company has all necessary corporate power and authority
          to execute and deliver the Exchange Agent Agreement and to consummate
          the transactions contemplated thereby and perform the obligations
          thereunder; and the Exchange Agent Agreement has been duly authorized,
          executed and delivered by the Company and, assuming the due
          authorization, execution and delivery thereof by the parties thereto
          other than the Company, constitutes a valid and binding obligation of
          the Company, enforceable against the Company in accordance with its
          terms, except that such opinion shall be qualified to the extent that
          enforceability of the Exchange Agent Agreement may be limited by
          applicable bankruptcy, reorganization, insolvency, liquidation,
          conservatorship, readjustment of debt, moratorium or other similar
          laws generally affecting the enforcement of the rights of creditors,
          and such opinion shall be subject to the limitations imposed by
          applicable law or equitable principles upon the specific
          enforceability of any of the remedies, covenants or other provisions
          of the Indenture and upon the availability of injunctive relief or
          other equitable remedies;

            (xvii) as of the date of such opinion, the Company is the record
          owner of 11,975,000 shares of Armor All; all of such shares of Armor
          All held by the Company have been duly authorized and are validly
          issued, fully paid and non-assessable, are free of statutory and
          contractual preemptive rights, and are owned by the Company free and
          clear of any pledge, lien, adverse claim, security interest,
          restriction, equity or other encumbrance; and

                                      -16-
<PAGE>
 
          the Company has all necessary corporate power and authority to
          exchange shares of Armor All in accordance with the Indenture;

            (xviii) the Registration Statement has become effective under the
          Securities Act and, to such counsel's knowledge, no stop order
          proceedings with respect thereto have been instituted or are pending
          or threatened under the Securities Act and nothing has come to such
          counsel's attention to lead it to believe that such proceedings are
          contemplated, and any required filing of the Prospectus and any
          supplement pursuant thereto pursuant to Rule 424(b) of the rules and
          regulations has been made in the manner and within the time period
          required by Rule 424(b);

             (xix)  such counsel (1) is of the opinion that the Registration
          Statement and Prospectus and any supplements or amendments thereto
          (except for financial statements and schedules included therein as to
          which such counsel need not express any opinion) comply as to form in
          all material respects with the Securities Act and the rules and
          regulations of the Commission thereunder, (2) has no reason to believe
          that (except for financial statements and schedules included therein
          as to which such counsel need not express any belief and except for
          that part of the Registration Statement that constitutes the Form T-1
          heretofore referred to) the Registration Statement and the prospectus
          included therein at the time the Registration Statement became
          effective contained any untrue statement of a material fact or omitted
          to state a material fact required to be stated therein or necessary
          to make the statements therein not misleading, and (3) has no reason
          to believe that (except for financial statements and schedules
          included therein as to which such counsel need not express any belief)
          the Prospectus contains any untrue statement of a material fact or
          omits to state a material fact necessary in order to make the
          statements therein, in light of the circumstances under which they
          were made, not misleading.

          (e)  You shall have received on the Closing Date an opinion of Wilson,
     Sonsini, Goodrich & Rosati, Professional Corporation, counsel for the
     Underwriters, dated the Closing Date, covering the matters referred to in
     subparagraphs (vi), (vii), (viii), (xv) and (xix) of paragraph (d) above.

     With respect to subparagraphs (vii), (viii) and (xvi) of paragraph (d)
above, Pillsbury Madison & Sutro and Wilson, Sonsini, Goodrich & Rosati may rely
on New York counsel as to the validity, binding nature and enforceability of the
Indenture, the Debentures

                                      -17-
<PAGE>
 
and the Exchange Agent Agreement.  With respect to subparagraphs (xviii) and
(xix) of paragraph (d) above, Pillsbury Madison & Sutro and Wilson, Sonsini,
Goodrich & Rosati may state that their opinion and belief are based upon their
participation in the preparation of the Registration Statement and Prospectus
and any amendments or supplements thereto and review and discussion of the
contents thereof, but are without independent check or verification except as
specified.

          (f)  You shall have received, on each of the date hereof and the
     Closing Date, letters dated the date hereof or the Closing Date, as the
     case may be, in form and substance satisfactory to you, from Deloitte &
     Touche, independent public accountants, containing statements and
     information of the type ordinarily included in accountants' "comfort
     letters" to underwriters with respect to the financial statements and
     certain financial information contained in the Registration Statement and
     the Prospectus with respect to each of Armor All and the Company.

     All the agreements, opinions, certificates and letters mentioned above or
elsewhere in this Agreement shall be deemed in compliance with the provisions
hereof only if Wilson, Sonsini, Goodrich & Rosati, counsel for the Underwriters,
shall be reasonably satisfied that they comply in form and scope.

     The several obligations of the Underwriters to purchase Additional
Debentures hereunder are subject to the delivery to you on the Option Closing
Date of such documents as you may reasonably request with respect to the good
standing of the Company, and other matters related to the sale of the Additional
Debentures, and an opinion of counsel in form and substance satisfactory to
counsel for the Underwriters.


                                      VII.

     In further consideration of the agreements of the Underwriters herein
contained, each of the Company and Armor All covenants as follows:

          (a)  To furnish to you, without charge, two (2) signed copies of the
     Registration Statement (including exhibits thereto), and for delivery to
     each other Underwriter a conformed copy of the Registration Statement
     (without exhibits thereto) and, during the period mentioned in paragraph
     (c) below, as many copies of the Prospectus and any supplements and
     amendments thereto or to the Registration Statement as you may reasonably
     request.

                                      -18-
<PAGE>
 
          (b)  Before amending or supplementing the Registration Statement or
     the Prospectus, to furnish to you a copy of each such proposed amendment or
     supplement and to file no such proposed amendment or supplement to which
     you reasonably object.

          (c)  If, during such period after the first date of the public
     offering of the Debentures as, in the opinion of your counsel, the
     Prospectus is required by law to be delivered in connection with sales by
     an Underwriter or dealer, any event shall occur or condition exist as a
     result of which it is necessary to amend or supplement the Prospectus in
     order to make the statements therein, in the light of the circumstances
     when the Prospectus is delivered to a purchaser, not misleading, or if it
     is necessary to amend or supplement the Prospectus to comply with law,
     forthwith to prepare, file with the Commission and furnish, at its own
     expense, to the Underwriters and to the dealers (whose names and addresses
     you will furnish to the Company) to which Debentures may have been sold by
     you on behalf of the Underwriters and to any other dealers upon request,
     either amendments or supplements to the Prospectus so that the statements
     in the Prospectus as so amended or supplemented will not, in the light of
     the circumstances when the Prospectus is delivered to a purchaser, be
     misleading or so that the Prospectus, as amended or supplemented, will
     comply with law.

          (d)  To endeavor to qualify the Debentures and the Armor All Shares
     for offer and sale under the securities or Blue Sky laws of such
     jurisdictions as you shall reasonably request.

          (e)  To endeavor to cause the Debentures to be listed on the Nasdaq
     Stock Market, and to take such action as shall be necessary to comply with
     the rules and regulations of the Nasdaq Stock Market with respect to the
     Debentures.

          (f)  To make generally available to the Company's and Armor All's
     security holders and to you as soon as reasonably practicable an earnings
     statement covering the twelve-month period ending [_________________, 19__]
     that satisfies the provisions of Section 11(a) of the Securities Act and
     the rules and regulations of the Commission thereunder.

          (g)  During the period beginning on the date hereof and continuing to
     and including the Closing Date, not to offer, sell, contract to sell or
     otherwise dispose of any debt securities of the Company or warrants to
     purchase debt securities of the Company substantially similar to the
     Debentures (other than (i) the Debentures and (ii) commercial paper issued
     in the ordinary course of business), without your prior written consent.

                                     VIII.

     The Company agrees to pay or cause to be paid all taxes, if any, on the
transfer and sale of the Debentures and Armor All Shares being sold by the
Company.  The Company agrees to pay all costs and expenses incident to the
performance of the obligations of the Company and Armor All under this
Agreement, including, but not limited to, all expenses incident to the delivery
of the Debentures, the reasonable fees and expenses of counsel and accountants
for the Company and Armor All, the costs and expenses incident to the
preparation by the Company, printing and filing of the Registration Statement
(including all exhibits thereto) and the Prospectus and any amendments or
supplements thereto, the expenses of qualifying the Debentures and the Armor All
Shares under the securities or Blue Sky laws of various jurisdictions, all
filing fees payable in connection with the review of the offering of the
Debentures and the Armor All Shares by the National Association of Securities
Dealers, Inc., the cost of furnishing to the Underwriters the required copies
of the Registration Statement, Prospectus and this Agreement and any amendments
or supplements thereto.


                                      IX.

     In regard to the information contained in the Registration Statement and
Prospectus relating to Armor All, the Company and Armor All jointly and
severally agree to indemnify and hold harmless each Underwriter and each person,
if any, who controls any Underwriter within the meaning of either Section 15 of
the Securities Act or Section 20 of the Securities Exchange Act of 1934, as
amended (the "Exchange Act"), from and against any and all losses, claims,
damages and liabilities (including, without limitation, any legal or other
expenses reasonably incurred by any Underwriter or any such controlling person
in connection with defending or investigating any such action or claim) caused
by any untrue statement or alleged untrue statement of a material fact contained
in the Registration Statement or any amendment thereof, any preliminary
prospectus or the Prospectus (as amended or supplemented if the Company or Armor
All shall have furnished any amendments or supplements thereto), or caused by
any omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading, except insofar as
such losses, claims, damages or liabilities are caused by any such untrue
statement or omission or alleged untrue statement or omission based upon
information relating to any Underwriter furnished to the Company in writing by
such Underwriter through you expressly for use therein; provided however, that
the foregoing indemnity agreement with respect to any preliminary prospectus
shall not inure to the benefit of any Under-

                                      -20-
<PAGE>
 
writer from whom the person asserting any such losses, claims, damages or
liabilities purchased Debentures, or any person controlling such Underwriter,
if a copy of the Prospectus (as then amended or supplemented if the Company or
Armor All shall have furnished any amendments or supplements thereto) was not
sent or given by or on behalf of such Underwriter to such person, if required by
law so to have been delivered, at or prior to the written confirmation of the
sale of the Debentures to such person, and if the Prospectus (as so amended or
supplemented) would have cured the defect giving rise to such loss, claim,
damage or liability.

     The Company further agrees to indemnify and hold harmless each Underwriter
and each person, if any, who controls any Underwriter within the meaning of
either Section 15 of the Securities Act or Section 20 of the Securities Exchange
Act of 1934, as amended (the "Exchange Act"), from and against any and all
losses, claims, damages and liabilities (including, without limitation, any
legal or other expenses reasonably incurred by any Underwriter or any such
controlling person in connection with defending or investigating any such
action or claim) caused by any untrue statement or alleged untrue statement of a
material fact contained in the Registration Statement or any amendment thereof,
any preliminary prospectus or the Prospectus (as amended or supplemented if the
Company or Armor All shall have furnished any amendments or supplements
thereto), or caused by any omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein, in light of the circumstances under which they were made, not
misleading, except insofar as such losses, claims, damages or liabilities are
caused by any such untrue statement or omission or alleged untrue statement or
omission based upon information relating to any Underwriter furnished to the
Company in writing by such Underwriter through you expressly for use therein;
provided however, that the foregoing indemnity agreement with respect to any
preliminary prospectus shall not inure to the benefit of any Underwriter from
whom the person asserting any such losses, claims, damages or liabilities
purchased Debentures, or any person controlling such Underwriter, if a copy of
the Prospectus (as then amended or supplemented if the Company or Armor All
shall have furnished any amendments or supplements thereto) was not sent or
given by or on behalf of such Underwriter to such person, if required by law so
to have been delivered, at or prior to the written confirmation of the sale of
the Debentures to such person, and if the Prospectus (as so amended or
supplemented) would have cured the defect giving rise to such loss, claim,
damage or liability.

     Each Underwriter agrees, severally and not jointly, to indemnify and hold
harmless the Company and Armor All, the directors of the Company and Armor All,
the officers of the Company and Armor All who sign the Registration Statement
and each person, if any, who controls the Company or Armor All within the
meaning of either

                                      -21-
<PAGE>
 
Section 15 of the Securities Act or Section 20 of the Exchange Act from and
against any and all losses, claims, damages and liabilities (including, without
limitation, any legal or other expenses reasonably incurred in connection with
defending or investigating any such action or claim) caused by any untrue
statement or alleged untrue statement of a material fact contained in the
Registration Statement or any amendment thereof, any preliminary prospectus or
the Prospectus (as amended or supplemented if the Company shall have furnished
any amendments or supplements thereto), or caused by any omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading, but only with reference to information
relating to such Underwriter furnished to the Company in writing by such
Underwriter expressly for use in the Registration Statement, any preliminary
prospectus, the Prospectus or any amendments or supplements thereto.

     In case any proceeding (including any governmental investigation) shall be
instituted involving any person in respect of which indemnity may be sought
pursuant to any of the two preceding paragraphs, such person (the "indemnified
party") shall promptly notify the person against whom such indemnity may be
sought (the "indemnifying party") in writing and the indemnifying party, upon
request of the indemnified party, shall retain counsel reasonably satisfactory
to the indemnified party to represent the indemnified party and any others the
indemnifying party may designate in such proceeding and shall pay the
reasonable fees and disbursements of such counsel related to such proceeding.
In any such proceeding, any indemnified party shall have the right to retain its
own counsel, but the fees and expenses of such counsel shall be at the expense
of such indemnified party unless (i) the indemnifying party and the indemnified
party shall have mutually agreed to the retention of such counsel or (ii) the
named parties to any such proceeding (including any impleaded parties) include
both the indemnifying party and the indemnified party and representation of both
parties by the same counsel would be inappropriate due to actual or potential
differing interests between them.  It is understood that the indemnifying party
shall not, in respect of the legal expenses of any indemnified party in
connection with any proceeding or related proceedings in the same jurisdiction,
be liable for the fees and expenses of more than one separate firm (in addition
to any local counsel) for all such indemnified parties and that all such fees
and expenses shall be reimbursed as they are incurred.  In the case of any such
separate firm for the Underwriters and such control persons of Underwriters,
such firm shall be designated in writing by Morgan Stanley & Co. Incorporated.
In the case of any such separate firm for the Company and Armor All, and such
directors, officers and control persons of the Company and Armor All, such firm
shall be designated in writing by the Company and Armor All.  The indemnifying
party shall not be liable for any

                                      -22-
<PAGE>
 
settlement of any proceeding effected without its written consent, but if
settled with such consent or if there be a final judgment for the plaintiff, the
indemnifying party agrees to indemnify the indemnified party from and against
any loss or liability by reason of such settlement or judgment.  Notwithstanding
the foregoing sentence, if at any time an indemnified party shall have requested
an indemnifying party to reimburse the indemnified party for fees and expenses
of counsel as contemplated by the second and third sentences of this paragraph,
the indemnifying party agrees that it shall be liable for any settlement of any
proceeding effected without its written consent if (i) such settlement is
entered into more than 30 days after receipt by such indemnifying party of the
aforesaid request and (ii) such indemnifying party shall not have reimbursed the
indemnified party in accordance with such request prior to the date of such
settlement.  No indemnifying party shall, without the prior written consent of
the indemnified party, which shall not be unreasonably withheld, effect any
settlement of any pending or threatened proceeding.

     If the indemnification provided for in the first or second paragraph of
this Article IX is unavailable to an indemnified party or insufficient in
respect of any losses, claims, damages or liabilities referred to therein, then
each indemnifying party under such paragraph, in lieu of indemnifying such
indemnified party thereunder, shall contribute to the amount paid or payable by
such indemnified party as a result of such losses, claims, damages or
liabilities (i) in such proportion as is appropriate to reflect the relative
benefits received by the indemnifying party or parties on the one hand and the
indemnified party or parties on the other hand from the offering of the
Debentures or (ii) if the allocation provided by clause (i) above is not
permitted by applicable law, in such proportion as is appropriate to reflect not
only the relative benefits referred to in clause (i) above but also the relative
fault of the indemnifying party or parties on the one hand and of the
indemnified party or parties on the other hand in connection with the statements
or omissions that resulted in such losses, claims, damages or liabilities, as
well as any other relevant equitable considerations.  The relative benefits
received by the Company and Armor All on the one hand and the Underwriters on
the other hand in connection with the offering of the Debentures shall be deemed
to be in the same respective proportions as the net proceeds from the offering
of the Debentures (before deducting expenses) received by the Company and the
total underwriting discounts and commissions received by the Underwriters, in
each case as set forth in the table on the cover of the Prospectus, bear to the
aggregate public offering price of the Debentures.  The relative fault of the
Company and Armor All on the one hand and the Underwriters on the other hand
shall be determined by reference to, among other things, whether the untrue or
alleged untrue statement of a material fact or the omission or alleged omission
to state a material fact relates to information supplied by the Company and

                                      -23-
<PAGE>
 
Armor All or by the Underwriters and the parties' relative intent, knowledge,
access to information and opportunity to correct or prevent such statement or
omission.  The Underwriters' respective obligations to contribute pursuant to
this Article IX are several in proportion to the respective number of Debentures
they have purchased hereunder, and not joint.

     The Company, Armor All and the Underwriters agree that it would not be just
or equitable if contribution pursuant to this Article IX were determined by pro
rata allocation (even if the Underwriters were treated as one entity for such
purpose) or by any other method of allocation that does not take account of the
equitable considerations referred to in the immediately preceding paragraph.
The amount paid or payable by an indemnified party as a result of the losses,
claims, damages and liabilities referred to in the immediately preceding
paragraph shall be deemed to include, subject to the limitations set forth
above, any legal or other expenses reasonably incurred by such indemnified party
in connection with investigating or defending any such action or claim.
Notwithstanding the provisions of this Article IX, no Underwriter shall be
required to contribute any amount in excess of the amount by which the total
price at which the Debentures underwritten by it and distributed to the public
were offered to the public exceeds the amount of any damages that such
Underwriter has otherwise been required to pay by reason of such untrue or
alleged untrue statement or omission or alleged omission.  No person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation.  The remedies provided for in this
Article IX are not exclusive and shall not limit any rights or remedies which
may otherwise be available to any indemnified party at law or in equity.

     The indemnity and contribution provisions contained in this Article IX and
the representations and warranties of the Company and Armor All contained in
this Agreement shall remain operative and in full force and effect regardless of
(i) any termination of this Agreement, (ii) any investigation made by or on
behalf of any Underwriter or any person controlling any Underwriter, the Company
or any person controlling the Company, or Armor All or any person controlling
Armor All, and (iii) acceptance of and payment for any of the Debentures.


                                       X.

     This Agreement shall be subject to termination, in your sole discretion, by
notice given by you to the Company, if (a) after the execution and delivery of
this Agreement and prior to the Closing Date (i) trading generally shall have
been suspended or materially limited on or by, as the case may be, any of the
New York Stock

                                      -24-
<PAGE>
 
Exchange, the American Stock Exchange, or the National Association of Securities
Dealers, Inc., (ii) trading of any securities of the Company shall have been
suspended on any exchange or in any over-the-counter market, (iii) a general
moratorium on commercial banking activities in New York shall have been declared
by either Federal or New York State authorities, or (iv) there shall have
occurred any outbreak or escalation of hostilities or any change in financial
markets or any calamity or crisis that, in your judgment, is material and
adverse and (b) in the case of any of the events specified in clauses (a)(i)
through (iv), such event singly or together with any other such event makes it,
in your judgment, impracticable to market the Debentures on the terms and in the
manner contemplated in the Prospectus.


                                      XI.

     This Agreement shall become effective upon the later of (x) execution and
delivery hereof by the parties hereto and (y) release of notification of the
effectiveness of the Registration Statement by the Commission.

     If, on the Closing Date or the Option Closing Date, as the case may be, any
one or more of the Underwriters shall fail or refuse to purchase Debentures that
it or they have agreed to purchase hereunder on such date, and the aggregate
principal amount of Debentures which such defaulting Underwriter or Underwriters
agreed but failed or refused to purchase is not more than one-tenth of the
aggregate principal amount of Debentures to be purchased on such date, the other
Underwriters shall be obligated severally in the proportions that the number of
Firm Debentures set forth opposite their respective names in Schedule I bears to
the principal amount of Debentures set forth opposite the names of all such
non-defaulting Underwriters, or in such other proportions as you may specify, to
purchase the Debentures which such defaulting Underwriter or Underwriters agreed
but failed or refused to purchase on such date; provided that in no event shall
the principal amount of Debentures that any Underwriter has agreed to purchase
pursuant to Article III be increased pursuant to this Article XI by an amount in
excess of one-ninth of such principal amount of Debentures without the written
consent of such Underwriter.  If, on the Closing Date or the Option Closing
Date, as the case may be, any Underwriter or Underwriters shall fail or refuse
to purchase Debentures and the aggregate principal amount of Debentures with
respect to which such default occurs is more than one-tenth of the aggregate
principal amount of Debentures to be purchased on such date, and arrangements
satisfactory to you and the Company for the purchase of such Debentures are not
made within 36 hours after such default, this Agreement shall terminate without
liability on the part of any non-defaulting Underwriter or the Company.  In any
such case either you or the Company shall have the right to postpone the

                                      -25-
<PAGE>
 
Closing Date or the Option Closing Date, as the case may be, but in no event for
longer than seven days, in order that the required changes, if any, in the
Registration Statement and in the Prospectus or in any other documents or
arrangements may be effected.  Any action taken under this paragraph shall not
relieve any defaulting Underwriter from liability to the Company or any
nondefaulting Underwriter in respect of any default of such defaulting 
Underwriter under this Agreement.

     If this Agreement shall be terminated by the Underwriters, or any of them,
because of any failure or refusal on the part of the Company or Armor All to
comply with the terms or to fulfill any of the conditions of this Agreement, or
if for any reason the Company or Armor All shall be unable to perform its
obligations under this Agreement, the Company and Armor All, jointly and
severally, will reimburse the Underwriters or such Underwriters as have so

     and the date of the payment (which shall be not less than 25 days after the
     receipt by the Trustee of such notice, unless the Trustee shall consent to
     an earlier date), and at the same time the Company shall deposit with the
     Trustee an amount of money equal to the aggregate amount to be paid in
     respect of such Defaulted Interest or shall make arrangements satisfactory
     to the Trustee for such deposit prior to the date of the proposed payment,
     such money when deposited to be held in trust for the benefit of the
     Persons entitled to such Defaulted Interest as in this clause provided. 
     Thereupon the Trustee shall fix a special record date for the payment of
     such Defaulted Interest which shall be not more than 15 days and not less
     than 10 days prior to the date of the payment and not less than 10 days
     after the

                                      -8-
<PAGE>

     receipt by the Trustee of the notice of the proposed payment. The Trustee
     shall promptly notify the Company of such special record date and, in the
     name and at the expense of the Company, shall cause notice of the payment
     of such Defaulted Interest and the special record date therefor to be
     mailed, first-class postage prepaid, to each Debentureholder at his address
     as it appears in the Debenture register, not less than 10 days prior to
     such special record date.  Notice of the proposed payment of such Defaulted
     Interest and the special record date therefor having been so mailed, such
     Defaulted Interest shall be paid to the Persons in whose names the
     Debentures (or their respective Predecessor Debentures) were registered at
     the close of business on such special record date and shall no longer be
     payable pursuant to the following clause (2).

          (2)  The Company may make payment of any Defaulted Interest in any
     other lawful manner not inconsistent with the requirements of any
     securities exchange on which the Debentures may be listed, and upon such
     notice as may be required by such exchange, if, after notice given by the
     Company to the Trustee of the proposed payment pursuant to this clause,
     such manner of payment shall be deemed practicable by the Trustee.

     Section 2.4  Execution of Debentures.  The Debentures shall be signed in
                  -----------------------                                    
the name and on behalf of the Company by the facsimile signature of its
Chairman, its Chief Executive Officer, its President or any of its Vice
Presidents and attested by the facsimile signature of its Secretary or any of
its Assistant Secretaries (which may be printed, engraved or otherwise
reproduced thereon, by facsimile or otherwise).  Only such Debentures as shall
bear thereon a certificate of authentication substantially in the form set forth
on the form of Debenture attached as Exhibit A hereto, manually executed by the
Trustee (or an authenticating agent appointed by the Trustee as provided by
Section 16.11), shall be entitled to the benefits of this Indenture or be valid
or obligatory for any purpose.  Such certificate by the Trustee (or such an
authenticating agent) upon any Debenture executed by the Company shall be
conclusive evidence that the Debenture so authenticated has been duly
authenticated and delivered hereunder and that the holder is entitled to the
benefits of this Indenture.

     In case any officer of the Company who shall have signed any of the
Debentures shall cease to be such officer before the Debentures so signed shall
have been authenticated and delivered by the Trustee, or disposed of by the
Company, such Debentures nevertheless may be authenticated and delivered or
disposed of as though the Person who signed such Debentures had not ceased to be
such officer of the Company; and any Debenture may be signed on behalf of the
Company by such Persons as, at the actual date of the execution of such
Debenture, shall be the proper officers of the Company, although at the date of
the execution of this Indenture any such Person was not such an officer.

     Section 2.5  Substitution and Registration of Transfer of Debentures;
                  --------------------------------------------------------
Restrictions on Transfer; Depositary.  The Company shall cause to be kept at the
- ------------------------------------                                            
Corporate Trust Office of the Trustee a register (the register maintained in
such office and in any other office or agency of the Company designated pursuant
to Section 5.2 being herein sometimes collectively referred to as the "Debenture
register") in which, subject to such reasonable regulations as it may prescribe,
the Company shall provide for the registration of Debentures and of transfers of
Debentures.  Such Debenture register shall be in written form or in any form 
capable of being converted into written form within a reasonable period of
time. The Trustee is hereby appointed "Debenture registrar" for the purpose of
registering Debentures and transfers of Debentures as herein provided. The
Company may appoint one or more co-registrars in accordance with Section
5.2.    
     Upon surrender for registration of transfer of any Debenture to the
Debenture registrar or any co-registrar, and satisfaction of the requirements
for such transfer set forth in this Section 2.5, the Company shall execute, and
the Trustee shall authenticate and deliver, in the name of the designated
transferee or transferees, one or more new Debentures of any authorized
denominations and of a like aggregate principal amount.

     Debentures may be substituted for other Debentures of any authorized
denominations and of a like aggregate principal amount, upon surrender of the
Debentures to be substituted at any such office or agency.  Whenever any
Debentures are so surrendered for substitution, the Company shall execute, and
the Trustee shall authenticate and deliver, the Debentures which the
Debentureholder making the substitution is entitled to receive.

     All Debentures issued upon any registration of transfer or substitution of
Debentures shall be the valid obligations of the Company, evidencing the same
debt, and entitled to the same benefits under this Indenture, as the Debentures
surrendered upon such registration of transfer or substitution.

     Every Debenture presented or surrendered for registration of transfer or
for substitution shall (if so required by the Company or the Debenture
registrar) be duly endorsed, or be accompanied by a written instrument of
transfer in form satisfactory to the Company, and the Debenture shall be duly
executed by the Debentureholder thereof or his attorney duly authorized in
writing.
    
     No service charge shall be charged to the Debentureholders for any
registration of transfer or substitution of Debentures, but the Company may
require payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in connection with any registration of transfer or
substitution of Debentures.     

     In the event of a redemption of the Debentures in part, the Company will
not be required to register the transfer or substitution of Debentures for a
period of 15 days immediately preceding the date notice is given identifying the
serial numbers of the Debentures called for such redemption; or to register the
transfer

                                      -10-
<PAGE>

or substitution of any such Debenture, or portion thereof, called for
redemption.

     Section 2.6  Mutilated, Destroyed, Lost or Stolen Debentures. In case any
                  -----------------------------------------------             
Debenture shall become mutilated or be destroyed, lost or stolen, the Company in
its discretion may execute, and upon its request the Trustee or an
authenticating agent appointed by the Trustee shall authenticate and deliver, a
new Debenture, bearing a number not contemporaneously outstanding, in
substitution for the mutilated Debenture, or in lieu of and in substitution for
the Debenture so destroyed, lost or stolen.  In every case the applicant for a
substituted Debenture shall furnish to the Company, to the Trustee and, if
applicable, to such authenticating agent such security or indemnity as may be
required by them to save each of them harmless for any loss, liability, cost or
expense caused by or connected with such substitution, and, in every case of
destruction, loss or theft, the applicant shall also furnish to the Company, to
the Trustee and, if applicable, to such authenticating agent evidence to their
satisfaction of the destruction, loss or theft of such Debenture and of the
ownership thereof.

     The Trustee or such authenticating agent may authenticate any such
substituted Debenture and deliver the same upon the receipt of such security or
indemnity as the Trustee, the Company and, if applicable, such authenticating
agent may require.  Upon the issuance of any substituted Debenture, the Company
may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
expenses connected therewith.  In case any Debenture which has matured or is
about to mature or has been called for redemption or is about to be exchanged
for Exchange Property shall become mutilated or be destroyed, lost or stolen,
the Company may, instead of issuing a substitute Debenture, pay or authorize the
payment of or exchange or authorize the exchange of the same (without surrender
thereof except in the case of a mutilated Debenture), as the case may be, if the
applicant for such payment or exchange shall furnish to the Company, to the
Trustee and, if applicable, to such authenticating agent such security or
indemnity as may be required by them to save each of them harmless for any loss,
liability, cost or expense caused by or connected with such substitution, and,
in case of destruction, loss or theft, evidence satisfactory to the Company, the
Trustee and, if applicable, any paying agent or the Exchange Agent of the
destruction, loss or theft of such Debenture and of the ownership thereof.

     Every substitute Debenture issued pursuant to the provisions of this
Section 2.6 by virtue of the fact that any Debenture is destroyed, lost or
stolen shall constitute an additional contractual obligation of the Company,
whether or not the destroyed, lost or stolen Debenture shall be found at any
time, and shall be entitled to all the benefits of (but shall be subject to all
the limitations set forth in) this Indenture equally and proportionately with
any and all other Debentures duly issued hereunder.  To the extent permitted by
law, all Debentures shall be held and owned

                                      -11-
<PAGE>

upon the express condition that the foregoing provisions are exclusive with
respect to the substitution or payment or exchange of mutilated, destroyed, lost
or stolen Debentures and shall preclude any and all other rights or remedies
notwithstanding any law or statute existing or hereafter enacted to the contrary
with respect to the substitution or payment or exchange of negotiable
instruments or other securities without their surrender.

     Section 2.7  Temporary Debentures.  Pending the preparation of definitive
                  --------------------                                        
Debentures, the Company may execute and the Trustee or an authenticating agent
appointed by the Trustee shall authenticate and deliver temporary Debentures
(printed or lithographed). Temporary Debentures shall be issuable in any
authorized denomination, and substantially in the form of the definitive
Debentures but with such omissions, insertions and variations as may be
appropriate for temporary Debentures, all as may be determined by the Company. 
Every such temporary Debenture shall be executed by the Company and
authenticated by the Trustee or such authenticating agent upon the same
conditions and in substantially the same manner, and with the same effect, as
the definitive Debentures. Without unreasonable delay the Company will execute
and deliver to the Trustee or such authenticating agent definitive Debentures
and thereupon any or all temporary Debentures may be surrendered in substitution
therefor, at each office or agency maintained by the Company pursuant to Section
5.2 and the Trustee or such authenticating agent shall authenticate and deliver
in substitution for such temporary Debentures an equal aggregate principal
amount of definitive Debentures.  Such substitution shall be made by the Company
at its own expense and without any charge therefor.  Until so substituted, the
temporary Debentures shall in all respects be entitled to the same benefits and
subject to the same limitations under this Indenture as definitive Debentures
authenticated and delivered hereunder.

     Section 2.8  Cancellation of Debentures Paid, etc.  All Debentures
                  -------------------------------------                
surrendered for the purpose of payment, redemption, exchange, substitution or
registration of transfer, shall, if surrendered to the Company or any paying
agent or any Debenture registrar or the Exchange Agent, be surrendered to the
Trustee and promptly canceled by it, or, if surrendered to the Trustee, shall be
promptly canceled by it, and no Debentures shall be issued in lieu thereof
except as expressly permitted by any of the provisions of this Indenture.  The
Trustee shall destroy canceled Debentures (unless the Company directs it to do
otherwise) and, after such destruction, shall deliver a certificate of such
destruction to the Company.  If the Company shall acquire any of the Debentures,
such acquisition shall not operate as a redemption or satisfaction of the
indebtedness represented by such Debentures unless and until the same are
delivered to the Trustee for cancellation.

                            REDEMPTION OF DEBENTURES

     Section 3.1  Redemption Prices.  The Company may, at its option, redeem

all or from time to time any part of the Debentures on any date prior to
maturity, upon notice as set forth in Section 3.2, and at the optional
redemption prices set forth in the form of Debenture attached as Exhibit A
hereto, together with accrued interest to the date fixed for redemption;
provided, however, that no such redemption shall be effected before February 16,
- -----------------                                                               
1999.

     Section 3.2  Notice of Redemption; Selection of Debentures. In case the
                  ---------------------------------------------             
Company shall desire to exercise the right to redeem all or, as the case may be,
any part of the Debentures pursuant to Section 3.1, it shall fix a date for
redemption and, in the case of any redemption pursuant to Section 3.1, it or, at
its request, the Trustee in the name of and at the expense of the Company (where
such request must be received by the Trustee at least 10 Business Days prior to
the date the Trustee is requested to give notice as described below unless a
shorter period is agreed to by the Trustee) shall mail or cause to be mailed a
notice of such redemption at least 30 and not more than 60 days prior to the
date fixed for redemption to the holders of Debentures so to be redeemed as a
whole or in part at their last addresses as the same appear on the Debenture
register of the Company (provided that if the Company shall give such notice, it
                         --------                                               
shall also give such notice, and notice of the Debentures to be redeemed, to the
Trustee).  Such mailing shall be by first-class mail.  The notice, if mailed in
the manner herein provided, shall be conclusively presumed to have been duly
given, whether or not the holder receives such notice.  In any case, failure to
give such notice by mail or any defect in the notice to the holder of any
Debenture designated for redemption as a whole or in part shall not affect the
validity of the proceedings for the redemption of any other Debenture.

     Each such notice of redemption shall specify the aggregate principal
amount of Debentures to be redeemed, the date fixed for redemption, the
redemption price at which Debentures are to be redeemed, the place or places of
payment, that payment will be made upon presentation and surrender of such
Debentures, that interest accrued to the date fixed for redemption will be paid
as specified in said notice, and that on and after said date interest thereon or
on the portion thereof to be redeemed will cease to accrue.  Such notice shall
also state the current Exchange Price and the date on which the right to
exchange such Debentures or portions thereof into Exchange Property will expire.
If fewer than all the Debentures are to be redeemed, the notice of redemption
shall identify the Debentures to be redeemed.  In case any Debenture is to be
redeemed in part only, the notice of redemption shall state the portion of the
principal amount thereof to be redeemed and shall state that on and after the
date fixed for redemption, upon surrender of such Debenture, a new Debenture or
Debentures in

                                      -13-
<PAGE>

principal amount equal to the unredeemed portion thereof will be issued.

     On or prior to the Business Day prior to the redemption date specified
in the notice of redemption given as provided in this Section 3.2, the Company
will deposit with the Trustee or with one or more paying agents (or, if the
Company is acting as its own paying agent, set aside, segregate and hold in
trust as provided in Section 5.4) an amount of money sufficient to redeem on the
redemption date all the Debentures so called for redemption (other than those
theretofore surrendered for exchange into Exchange Property) at the appropriate
redemption price, together with accrued interest to the date fixed for
redemption.  If any Debenture called for redemption is exchanged pursuant
hereto, any money deposited with the Trustee or any paying agent or so
segregated and held in trust for the redemption of such Debenture shall be paid
to the Company upon its request, or, if then held by the Company shall be
discharged from such trust.  If fewer than all the Debentures are to be
redeemed, the Company will give the Trustee written notice in the form of an
Officer's Certificate not fewer than 45 days (or such shorter period of time as
may be acceptable to the Trustee) prior to the redemption date as to the
aggregate principal amount of Debentures to be redeemed.
    
     If fewer than all the Debentures are to be redeemed, the Trustee shall
select, by lot or, in its sole discretion, on a pro rata basis, the Debentures
or portion thereof (in integral multiples of $1,000) to be redeemed.  If any
Debenture selected for partial redemption is exchanged in part after such
selection, the exchanged portion of such Debenture shall be deemed (so far as
may be) to be the portion to be selected for redemption.  The Debentures (or
portions thereof) so selected shall be deemed duly selected for redemption for
all purposes hereof, notwithstanding that any such Debenture is exchanged as a
whole or in part before the mailing of the notice of redemption.     

     Upon any redemption of less than all Debentures, the Company and the
Trustee may treat as outstanding any Debentures surrendered for exchange during
the period of 15 days next preceding the mailing of a notice of redemption and
need not treat as outstanding any Debenture authenticated and delivered during
such period in substitution for the unexchanged portion of any Debenture
exchanged in part during such period.

     Section 3.3  Payment of Debentures Called for Redemption.  If notice of
                  -------------------------------------------               
redemption has been given as above provided, the Debentures or portion of
Debentures with respect to which such notice has been given shall, unless
exchanged into Exchange Property pursuant to the terms hereof, become due and
payable on the date and at the place or places stated in such notice at the
applicable redemption price, together with interest accrued to the date fixed
for redemption, and on and after said date (unless the Company shall default in
the payment of such Debentures at the redemption price, together with interest
accrued to said date) interest on the

                                      -14-
<PAGE>

Debentures or portion of Debentures so called for redemption shall cease to
accrue and such Debentures shall cease after the close of business on the
Business Day next preceding the date fixed for redemption to be exchangeable
into Exchange Property and, except as provided in Sections 8.5 and 13.5, to be
entitled to any benefit or security under this Indenture, and the holders
thereof shall have no right in respect of such Debentures except the right to
receive the redemption price thereof and unpaid interest to the date fixed for
redemption.  On presentation and surrender of such Debentures at a place of
payment in said notice specified, the said Debentures or the specified portions
thereof shall be paid and redeemed by the Company at the applicable redemption
price, together with interest accrued thereon to the date fixed for redemption;
provided that any semi-annual payment of interest becoming due on the date fixed
- --------                                                                        
for redemption shall be payable to the holders of such Debentures registered as
such on the relevant record date subject to the terms and provisions of Section
2.3 hereof.

     Upon presentation of any Debenture redeemed in part only, the Company
shall execute and the Trustee shall authenticate and deliver to the holder
thereof, at the expense of the Company, a new Debenture or Debentures, of
authorized denominations, in principal amount equal to the unredeemed portion of
the Debentures so presented.

     Notwithstanding the foregoing, the Trustee shall not redeem any
Debentures or mail any notice of optional redemption during the continuance of a
default in payment of interest or premium on the Debentures or of any Event of
Default of which, in the case of any Event of Default other than under Section
7.1(a) or (b), a Responsible Officer of the Trustee has knowledge.  If any
Debenture called for redemption shall not be so paid upon surrender thereof for
redemption, the principal and premium, if any, shall, until paid or duly
provided for, bear interest from the date fixed for redemption at the rate borne
by the Debenture and such Debenture shall remain exchangeable into Exchanged
Property until the principal and premium, if any, shall have been paid or duly
provided for.

     Section 3.4  Exchange Arrangement on Call for Redemption.  In connection
                  -------------------------------------------                
with any redemption of Debentures, the Company may arrange for the purchase and
exchange of any Debentures by an agreement with one or more investment bankers
or other purchasers to purchase such Debentures by paying to the Trustee in
trust for the Debentureholders, on or before the date fixed for redemption, an
amount not less than the applicable redemption price, together with interest
accrued to the date fixed for redemption, of such Debentures.  Notwithstanding
anything to the contrary contained in this Article III, the obligation of the
Company to pay the redemption price of such Debentures, together with interest
accrued to the date fixed for redemption, shall be deemed to be satisfied and
discharged to the extent such amount is so paid by such purchasers. If such an
agreement is entered into, a copy of which will be filed with the Trustee prior
to the date fixed for redemption, any

                                      -15-
<PAGE>

Debentures not duly surrendered for exchange by the holders thereof may, at the
option of the Company, be deemed, to the fullest extent permitted by law,
acquired by such purchasers from such holders and (notwithstanding anything to
the contrary contained in Article XV) surrendered by such purchasers for
exchange, all as of immediately prior to the close of business on the date fixed
for redemption (and the right to exchange any such Debentures shall be deemed to
have been extended through such time), subject to payment of the above amount as
aforesaid.  At the direction of the Company, the Trustee shall hold and dispose
of any such amount paid to it in the same manner as it would monies deposited
with it by the Company for the redemption of Debentures.  Without the Trustee's
prior written consent, no arrangement between the Company and such purchasers
for the purchase and exchange of any Debentures shall increase or otherwise
affect any of the powers, duties, responsibilities or obligations of the Trustee
as set forth in this Indenture, and the Company agrees to indemnify the Trustee
from, and hold it harmless against, any loss, liability or expense arising out
of or in connection with any such arrangement for the purchase and exchange of
any Debentures between the Company and such purchasers to which the Trustee has
not consented in writing, including the costs and expenses incurred by the
Trustee in the defense of any claim or liability arising out of or in connection
with the exercise or performance of any of its powers, duties, responsibilities
or obligations under this Indenture.


                                  ARTICLE IV.

                          SUBORDINATION OF DEBENTURES

     Section 4.1  Agreement of Subordination.  The Company covenants and
                  --------------------------                            
agrees, and each holder of Debentures issued hereunder by his acceptance thereof
likewise covenants and agrees, that all Debentures shall be issued subject to
the provisions of this Article IV; and each Person holding any Debenture,
whether upon original issue or upon transfer or assignment thereof, accepts and
agrees to be bound by such provisions.

     The payment of the principal of, premium, if any, and interest on all
Debentures issued hereunder shall, to the extent and in the manner hereinafter
set forth, be subordinated and subject in right of payment to the prior payment
in full of all Senior Indebtedness, whether outstanding at the date of this
Indenture or thereafter incurred.

     No provision of this Article IV shall prevent the occurrence of any Event 
of Default hereunder.

     Section 4.2  Payments to Debentureholders.  In the event and during the
                  ----------------------------                              
continuation of any default in the payment of principal, premium, interest or
any other payment due on any Senior Indebtedness continuing beyond the period of
grace, if any, specified in the instrument or lease evidencing such Senior

                                      -16-
<PAGE>

Indebtedness, then, unless and until such default shall have been cured or
waived or shall have ceased to exist, no payment shall be made by the Company
with respect to the principal of, or premium, if any, or interest on the
Debentures except payments made pursuant to Article XIII from monies deposited
with the Trustee pursuant thereto prior to the happening of such default.
    
     Upon any payment by the Company, or distribution of assets of the
Company of any kind or character, whether in cash, property or securities, to
creditors upon any dissolution or winding-up or liquidation or reorganization of
the Company, whether voluntary or involuntary or in bankruptcy, insolvency,
receivership or other proceedings, all amounts due or to become due upon all
Senior Indebtedness shall first be paid in full, or payment thereof provided for
in money in accordance with its terms, before any payment is made on account of
the principal (and premium, if any) or interest on the Debentures (except
payments made pursuant to Article XIII from monies deposited with the Trustee
pursuant thereto prior to the happening of such dissolution, winding-up,
liquidation or reorganization); and upon any such dissolution or winding-up or
liquidation or reorganization, any payment by the Company, or distribution of
assets of the Company of any kind or character, whether in cash, property or
securities, to which the holders of the Debentures or the Trustee would be
entitled, except for the provision of this Article IV, shall (except as
aforesaid) be paid by the Company or by any receiver, trustee in bankruptcy,
liquidating trustee, agent or other Person making such payment or distribution,
or by the holders of the Debentures or by the Trustee under this Indenture if
received by them or it, directly to the holders of Senior Indebtedness (pro rata
to such holders on the basis of the respective amounts of Senior Indebtedness
held by such holders, as calculated by the Company, or as otherwise required by
law or a court order) or their representative or representatives, or to the
trustee or trustees under any indenture pursuant to which any instruments
evidencing any Senior Indebtedness may have been issued, as their respective
interests may appear, to the extent necessary to pay all Senior Indebtedness in
full, in money or money's worth, after giving effect to any concurrent payment
or distribution to or for the holders of Senior Indebtedness, before any payment
or distribution is made to the holders of the Debentures or to the Trustee.     

     In the event that, notwithstanding the foregoing, any payment or
distribution of assets of the Company of any kind or character, whether in cash,
property or securities, prohibited by the foregoing, shall be received by the
Trustee or the holders of the Debentures before all Senior Indebtedness is paid
in full, or provision is made for such payment in money in accordance with its
terms, such payment or distribution shall be held in trust for the benefit of
and shall be paid over or delivered to the holders of Senior Indebtedness or

the Company, for application to the payment of all Senior Indebtedness remaining
unpaid to the extent necessary to pay all Senior Indebtedness in full in money
in accordance with its terms, after giving effect to any concurrent payment or
distribution to or for the holders of such Senior Indebtedness.
    
     For purposes of this Article IV, the words, "cash, property or securities"
shall not be deemed to include shares of stock of the Company as reorganized or
readjusted, or securities of the Company or any other corporation provided for
by a plan of reorganization or readjustment, the payment of which is
subordinated at least to the extent provided in this Article IV with respect to
the Debentures to the payment of all Senior Indebtedness which may at the time
be outstanding; provided that (i) if a new corporation results from such
                --------
reorganization or readjustment, such corporation  assumes the Senior
Indebtedness (other than leases which need not be assumed), and (ii) the rights
of the holders of Senior Indebtedness (other than leases which are not assumed
by the Company or by the new corporation, as the case may be) are not, without
the consent of such holders, altered by such reorganization or readjustment. The
consolidation of the Company with, or the merger of the Company into, another
corporation or the liquidation or dissolution of the Company following the
conveyance or transfer of its property as an entirety, or substantially as an
entirety, to another corporation upon the terms and conditions provided for in
Article XII shall not be deemed a dissolution, winding-up, liquidation or
reorganization for the purposes of this Section 4.2 if such other corporation
shall, as a part of such consolidation, merger, conveyance or transfer, comply
with the conditions stated in Article XII.  Nothing in this Section 4.2 shall
apply to claims of, or payments to, the Trustee under or pursuant to Section
8.6.     

     Section 4.3  Subrogation of Debentures.  Subject to the payment in full
                  -------------------------                                 
of all Senior Indebtedness, the rights of the holders of the Debentures shall be
subrogated to the rights of the holders of Senior Indebtedness to receive
payments or distributions of cash, property or securities of the Company
applicable to the Senior Indebtedness until the principal of (and premium, if
any) and interest on the Debentures shall be paid in full; and, for the purposes
of such subrogation, no payments or distributions to the holders of the Senior
Indebtedness of any cash, property or securities to which the holders of the
Debentures or the Trustee would be entitled except for the provisions of this
Article IV, and no payment pursuant to the provisions of this Article IV to or
for the benefit of the holders of Senior Indebtedness by holders of the
Debentures or the Trustee, shall, as between the Company, its creditors other
than holders of Senior Indebtedness, and the holders of the Debentures, be
deemed to be a payment by the Company to or on account of the Senior
Indebtedness.  It is understood that the provisions of this Article IV are and
are intended solely for the purposes of defining the relative rights of the
holders of the Debentures, on the one hand, and the holders of the Senior
Indebtedness, on the other hand.

     Nothing contained in this Article IV or elsewhere in this Indenture or
in the Debentures is intended to or shall impair, as among the Company, its
creditors other than the holders of Senior Indebtedness, and the holders of the
Debentures, the obligation of the Company, which is absolute and unconditional,
to pay to the holders of the Debentures the principal of (and premium, if any)
and interest on the Debentures as and when the same shall become due and payable
in accordance with their terms, or is intended to or shall affect the relative
rights of the holders of the Debentures and creditors of the Company other than
the holders of the Senior Indebtedness, nor shall anything herein or therein
prevent the Trustee or the holder of any Debenture from exercising all remedies
otherwise permitted by applicable law upon an Event of Default under this
Indenture, subject to the rights, if any, under this Article IV of the holders
of Senior Indebtedness in respect of cash, property or securities of the Company
received upon the exercise of any such remedy.     
    
     Upon any payment or distribution of assets of the Company referred to in
this Article IV, the Trustee, subject to the provisions of Section 8.1, and the
holders of the Debentures shall be entitled to rely upon any order or decree
made by any court of competent jurisdiction in which such bankruptcy,
dissolution, winding-up, liquidation or reorganization proceedings are pending,
or a certificate of the receiver, trustee in bankruptcy, liquidating trustee,
agent or other person making such payment or distribution, delivered to the
Trustee or to the holders of the Debentures, for the purpose of ascertaining the
persons entitled to participate in such distribution, the holders of the Senior
Indebtedness and other indebtedness of the Company, the amount thereof or
payable thereon, the amount or amounts paid or distributed thereon, and all 
other facts pertinent thereto or to this Article IV.     
    
     Section 4.4  Authorization by Debentureholders.  Each holder of a
                  ---------------------------------                   
Debenture by his acceptance thereof authorizes and directs the Trustee on his
behalf to take such action as may be necessary or appropriate to effectuate the
subordination provided in this Article IV and appoints the Trustee his
attorney-in-fact for any and all such purposes.     

     Section 4.5  Notice to Trustee.  The Company shall give prompt written
                  -----------------                                        
notice in the form of an Officer's Certificate to a Responsible Officer of the
Trustee of any fact known to the Company which would prohibit the making of any
payment of monies to or by the Trustee in respect of the Debentures pursuant to
the provisions of this Article IV.  Notwithstanding the provisions of this
Article IV or any other provision of this Indenture, the Trustee shall not be
charged with knowledge of the existence of any facts which would prohibit the
making of any payment of monies to or by the Trustee in respect of the
Debentures pursuant to the provisions of this Article IV, unless and until a
Responsible Officer of the Trustee shall have received written notice thereof at
the Corporate Trust Office of the Trustee from the Company (in the form of an
Officer's Certificate) or a holder or holders of Senior Indebtedness or from any
trustee thereof; and before the receipt of any

                                      -19-
<PAGE>

such written notice, the Trustee, subject to the provisions of Section 8.1,
shall be entitled in all respects to assume that no such facts exist; provided
                                                                      --------
that if on a date not fewer than two Business Days prior to the date upon which
by the terms hereof any such monies may become payable for any purpose
(including, without limitation, the payment of the principal of, or premium, if
any, or interest on any Debenture) the Trustee shall not have received, with
respect to such monies, the notice provided for in this Section 4.5, then,
anything herein contained to the contrary notwithstanding, the Trustee shall
have full power and authority to receive such monies and to apply the same to
the purpose for which they were received, and shall not be affected by any
notice to the contrary which may be received by it on or after such prior date.

     Notwithstanding anything to the contrary hereinbefore set forth, nothing
shall prevent any payment by the Company or the Trustee to the Debentureholders
of monies in connection with a redemption of Debentures if (i) notice of such
redemption has been given pursuant to Article III or Section 13.1 prior to the
receipt by the Trustee of written notice as aforesaid, and (ii) such notice of
redemption is given not earlier than 60 days before the redemption date.

     The Trustee, subject to the provisions of Section 8.1, shall be entitled
to rely on the delivery to it of a written notice by a Person representing
himself to be a holder of Senior Indebtedness (or a trustee on behalf of such
holder) to establish that such notice has been given by a holder of Senior
Indebtedness or a trustee on behalf of any such holder or holders.  In the event
that the Trustee determines in good faith that further evidence is required with
respect to the right of any Person as a holder of Senior Indebtedness to
participate in any payment or distribution pursuant to this Article IV, the
Trustee may request such Person to furnish evidence to the reasonable
satisfaction of the Trustee as to the amount of Senior Indebtedness held by such
Person, the extent to which such Person is entitled to participate in such
payment or distribution and any other facts pertinent to the rights of such
Person under this Article IV, and if such evidence is not furnished the Trustee
may defer any payment to such Person pending judicial determination as to the
right of such Person to receive such payment.

                  -----------------------------------------                 
its individual capacity shall be entitled to all the rights set forth in this
Article IV in respect of any Senior Indebtedness at any time held by it, to the
same extent as any other holder of Senior Indebtedness, and nothing in Section
8.13 or elsewhere in this Indenture shall deprive the Trustee of any of its
rights as such holder.

     With respect to the holders of Senior Indebtedness, the Trustee
undertakes to perform or to observe only such of its covenants and obligations
as are specifically set forth in this Article IV, and no implied covenants or
obligations with respect to

                                      -20-
<PAGE>

the holders of Senior Indebtedness shall be read into this Indenture against the
Trustee.  The Trustee shall not be deemed to owe any fiduciary duty to the
holders of Senior Indebtedness and, subject to the provisions of Section 8.1,
the Trustee shall not be liable to any holder of Senior Indebtedness if it shall
pay over or deliver to holders of Debentures, the Company or any other Person
money or assets to which any holder of Senior Indebtedness shall be entitled by
virtue of this Article IV or otherwise.

    Section 4.7  No Impairment of Subordination.  No right of any present or
                 ------------------------------                             
future holder of any Senior Indebtedness to enforce subordination as herein
provided shall at any time in any way be prejudiced or impaired by any act or
failure to act on the part of the Company or by any act or failure to act, in
good faith, by any such holder, or by any noncompliance by the Company with the
terms, provisions and covenants of this Indenture, regardless of any knowledge
thereof which any such holder may have or otherwise be charged with.

     at least 50% of the consolidated assets of the Company, McKesson-Maryland, 
     seeking liquidation, reorganization or other relief with respect to it or
     its debts under any bankruptcy, insolvency or other similar law now or
     hereafter in effect or seeking the appointment of a trustee, receiver,
     liquidator, custodian or other similar official of it or any substantial
     part of its property, and such involuntary case or other proceeding shall
     remain undismissed and unstayed for a period of 90 consecutive days;
    
then, and in each and every such case (other than an Event of Default specified
in Section 7.1(f) or (g)), unless the principal of all of the Debentures shall
have already become due and payable, either the Trustee or the holders of not
less than 25 percent in aggregate principal amount of the Debentures then
outstanding hereunder determined in accordance with Section 9.4, by notice in
writing to the Company (and to the Trustee if given by Debentureholders) may
declare the principal of and premium, if any, on all the Debentures and the
interest accrued thereon to be due and payable immediately, and upon any such
declaration the same shall become and shall be immediately due and payable,
anything in this Indenture or in the Debentures contained to the contrary
notwithstanding.  If an Event of Default specified in Section 7.1(f) or (g)
occurs and is continuing, the principal of and premium, if any, on all the
Debentures and the interest     

                                      -26-
<PAGE>

accrued thereon shall be immediately due and payable.  This provision, however,
is subject to the conditions that if, at any time after the principal of the
Debentures shall have been so declared due and payable, and before any judgment
or decree for the payment of the monies due shall have been obtained or entered
as hereinafter provided, the Company shall pay or shall deposit with the Trustee
a sum sufficient to pay all matured installments of interest upon all Debentures
and the principal of and premium, if any, on any and all Debentures which shall
have become due otherwise than by acceleration (with interest on overdue
installments of interest (to the extent that payment of such interest is
enforceable under applicable law) and on such principal and premium, if any, at
the rate borne by the Debentures, to the date of such payment or deposit) and
amounts due to the Trustee pursuant to Section 8.6, and if any and all Events of
Default under this Indenture, other than the nonpayment of principal of and
premium, if any, and accrued interest on Debentures which shall have become due
by acceleration, shall have been cured or waived pursuant to Section 7.7, then
and in every such case the holders of a majority in aggregate principal amount
of the Debentures then outstanding, by written notice to the Company and to the
Trustee, may waive all Events of Default and rescind and annul such declaration
and its consequences; but no such waiver or rescission and annulment shall
extend to or shall affect any subsequent Event of Default, or shall impair any
right consequent thereon.  The Company shall notify a Responsible Officer of the
Trustee, promptly upon becoming aware thereof, of any Event of Default.

     In case the Trustee shall have proceeded to enforce any right under this
Indenture and such proceedings shall have been discontinued or abandoned because
of such waiver or rescission and annulment or for any other reason or shall have
been determined adversely to the Trustee, then and in every such case the
Company, the holders of Debentures and the Trustee shall be restored
respectively to their several positions and rights hereunder, and all rights,
remedies and powers of the Company, the holders of Debentures and the Trustee
shall continue as though no such proceeding had been taken.

     Section 7.2  Payments of Debentures on Default; Suit Therefor. The Company
                  ------------------------------------------------             
covenants that (a) in case default shall be made in the payment of any
installment of interest upon any of the Debentures as and when the same shall
become due and payable, and such default shall have continued for a period of 30
days, or (b) in case default shall be made in the payment of the principal of or
premium, if any, on any of the Debentures as and when the same shall have become
due and payable, whether at maturity of the Debentures or in connection with any
redemption, by declaration or otherwise, then, upon demand of the Trustee, the
Company will pay to the Trustee, for the benefit of the holders of the
Debentures, the whole amount that then shall have become due and payable on all
such Debentures for principal and premium, if any, or interest, or both, as the
case may be, with interest upon the overdue principal and premium, if any, and
(to the extent that payment of such

                                      -27-
<PAGE>

interest is enforceable under applicable law) upon the overdue installments of
interest at the rate borne by the Debentures; and, in addition thereto, such
further amount as shall be sufficient to cover the costs and expenses of
collection, including reasonable compensation to the Trustee, its agents,
attorneys and counsel, and any expenses or liabilities incurred by the Trustee
hereunder other than through its negligence or bad faith.  Until such demand by
the Trustee, the Company may pay the principal of and premium, if any, and
interest on the Debentures to the registered holders, whether or not the
Debentures are overdue.

     In case the Company shall fail forthwith to pay such amounts upon such
demand, the Trustee, in its own name and as trustee of an express trust, shall
be entitled and empowered to institute any action or proceeding at law or in
equity for the collection of the sums so due and unpaid, and may prosecute any
such action or proceeding to judgment or final decree, and may enforce any such
judgment or final decree against the Company or any other obligor on the
Debentures and collect in the manner provided by law out of the property of the
Company or any other obligor on the Debentures wherever situated the monies
adjudged or decreed to be payable.

     In the event there shall be pending proceedings for the bankruptcy or for
the reorganization of the Company or any other obligor on the Debentures under
Title 11 of the United States Code, or any other applicable law, or in case a
receiver, assignee or trustee in bankruptcy or reorganization, liquidator,
sequestrator or similar official shall have been appointed for or taken
possession of the Company or such other obligor, the property of the Company or
such other obligor, or in the case of any other judicial proceedings relative to
the Company or such other obligor upon the Debentures, or to the creditors or
property of the Company or such other obligor, the Trustee, irrespective of
whether the principal of the Debentures shall then be due and payable as therein
expressed or by declaration or otherwise and irrespective of whether the Trustee
shall have made any demand pursuant to the provisions of this Section 7.2, shall
be entitled and empowered, by intervention in such proceedings or otherwise, to
file and prove a claim or claims for the whole amount of principal, premium, if
any, and interest owing and unpaid in respect of the Debentures, and, in case of
any judicial proceedings, to file such proofs of claim and other papers or
documents as may be necessary or advisable in order to have the claims of the
Trustee and of the Debentureholders allowed in such judicial proceedings
relative to the Company or any other obligor on the Debentures, its or their
creditors, or its or their property, and to collect and receive any monies or
other property payable or deliverable on any such claims, and to distribute the
same after the deduction of any amounts due the Trustee under Section 8.6; and
any receiver, assignee or trustee in bankruptcy or reorganization, liquidator,
custodian or similar official is hereby authorized by each of the
Debentureholders to make such payments to the Trustee, and, in the event that
the Trustee shall consent to the making of such payments directly to the
Debentureholders, to pay to the Trustee any amount due it for

                                      -28-
<PAGE>

reasonable compensation, expenses, advances and disbursements, including counsel
fees incurred by it up to the date of such distribution.  To the extent that
such payment of reasonable compensation, expenses, advances and disbursements
out of the estate in any such proceedings shall be denied for any reason,
payment of the same shall be secured by a lien on, and shall be paid out of, any
and all distributions, dividends, monies, securities and other property which
the holders of the Debentures may be entitled to receive in such proceedings,
whether in liquidation or under any plan of reorganization or arrangement or
otherwise.

     Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or adopt on behalf of any Debentureholder any plan of
reorganization or arrangement affecting the Debentures or the rights of any
Debentureholder, or to authorize the Trustee to vote in respect of the claim of
any Debentureholder in any such proceeding.

     All rights of action and of asserting claims under this Indenture, or under
any of the Debentures, may be enforced by the Trustee without the possession of
any of the Debentures, or the production thereof on any trial or other
proceeding relative thereto, and any such suit or proceeding instituted by the
Trustee shall be brought in its own name as trustee of an express trust, and any
recovery of judgment shall, after provision for the payment of the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, be for the ratable benefit of the holders of the Debentures.

     In any proceedings brought by the Trustee (and in any proceedings involving
the interpretation of any provision of this Indenture to which the Trustee shall
be a party) the Trustee shall be held to represent all the holders of the
Debentures, and it shall not be necessary to make any holders of the Debentures
parties to any such proceedings.

     Section 7.3  Application of Monies Collected by Trustee.  Any monies
                  ------------------------------------------             
collected by the Trustee pursuant to this Article VII shall be applied in the
order following, at the date or dates fixed by the Trustee for the distribution
of such monies, upon presentation of the several Debentures, and stamping
thereon the payment, if only partially paid, and upon surrender thereof, if
fully paid:

          First:  To the payment of all amounts due the Trustee under Section
     8.6;

          Second:  Subject to the provisions of Article IV, in case the
     principal of the outstanding Debentures shall not have become due and be
     unpaid, to the payment of interest on the Debentures in default in the
     order of the maturity of the installments of such interest, with interest
     (to the extent that such interest has been collected by the Trustee) upon
     the overdue installments of interest at the rate borne by the

                                      -29-
<PAGE>

     Debentures, such payments to be made ratably to the persons entitled
     thereto;

          Third:  Subject to the provisions of Article IV, in case the principal
     of the outstanding Debentures shall have become due, by declaration or
     otherwise, and be unpaid, to the payment of the whole amount then owing and
     unpaid upon the Debentures for principal and premium, if any, and interest,
     with interest on the overdue principal and premium, if any, and (to the
     extent that such interest has been collected by the Trustee) upon overdue
     installments of interest at the rate borne by the Debentures; and in case
     such monies shall be insufficient to pay in full the whole amounts so due
     and unpaid upon the Debentures, then to the payment of such principal and
     premium, if any, and interest without preference or priority of principal
     and premium, if any, over interest, or of interest over principal and
     premium, if any, or of any installment of interest over any other
     installment of interest, or of any Debenture over any other Debenture,
     ratably to the aggregate of such principal and premium, if any, and accrued
     and unpaid interest; and

          Fourth:  Subject to the provisions of Article IV, to the payment of
     the remainder, if any, to the Company or any other Person lawfully entitled
     thereto.

     Section 7.4  Proceedings by Debentureholder.  No holder of any Debenture
                  ------------------------------                             
shall have any right by virtue of or by availing of any provision of this
Indenture to institute any suit, action or proceeding in equity or at law upon
or under or with respect to this Indenture, or for the appointment of a
receiver, trustee, liquidator, custodian or other similar official, or for any
other remedy hereunder, unless such holder previously shall have given to the
Trustee written notice of an Event of Default and of the continuance thereof, as
hereinbefore provided, and unless also the holders of not less than 25 percent
in aggregate principal amount of the Debentures then outstanding shall have made
written request upon the Trustee to institute such action, suit or proceeding in
its own name as Trustee hereunder and shall have offered to the Trustee such
reasonable indemnity as it may require against the costs, expenses and
liabilities to be incurred therein or thereby, and the Trustee for 60 days after
its receipt of such notice, request and offer of indemnity shall have neglected
or refused to institute any such action, suit or proceeding and no direction
inconsistent with such written request shall have been given to the Trustee
pursuant to Section 7.7; it being understood and intended, and being expressly
covenanted by the taker and holder of every Debenture with every other taker and
holder and the Trustee, that no one or more holders of Debentures shall have any
right in any manner whatever by virtue of or by availing of any provision of
this Indenture to affect, disturb or prejudice the rights of any other holder of
Debentures, or to obtain or seek to obtain priority over or preference to any
other such holder, or to enforce any right under this Indenture, except in the
manner herein provided

                                      -30-
<PAGE>

and for the equal, ratable and common benefit of all holders of Debentures
(except as otherwise provided herein).  For the protection and enforcement of
this Section 7.4, each and every Debentureholder and the Trustee shall be
entitled to such relief as can be given either at law or in equity.

     Notwithstanding any other provision of this Indenture and any provision of
any Debenture, the right of any holder of any Debenture to receive payment of
the principal of and premium, if any, and interest on such Debenture, on or
after the respective due dates expressed in such Debenture, or to institute suit
for the enforcement of any such payment on or after such respective dates
against the Company shall not be impaired or affected without the consent of
such holder.
    
     Anything in this Indenture or the Debentures to the contrary
notwithstanding, the holder of any Debenture, without the consent of either the
Trustee or the holder of any other Debenture, in his own behalf and for his own
benefit, may enforce, and may institute and maintain any proceeding suitable to
enforce, his or her rights of exchange or repurchase as provided in Article 
XV.     

     Section 7.5  Proceedings by Trustee.   In case of an Event of Default the
                  ----------------------                                      
Trustee may in its discretion proceed to protect and enforce the rights vested
in it by this Indenture by such appropriate judicial proceedings as the Trustee
shall deem most effectual to protect and enforce any of such rights, either by
suit in equity or by action at law or by proceeding in bankruptcy or otherwise,
whether for the specific enforcement of any covenant or agreement contained in
this Indenture or in aid of the exercise of any power granted in this Indenture,
or to enforce any other legal or equitable right vested in the Trustee by this
Indenture or by law.

     Section 7.6  Remedies Cumulative and Continuing.  Except as provided in
                  ----------------------------------                        
Section 2.6, all powers and remedies given by this Article VII to the Trustee or
to the Debentureholders shall, to the extent permitted by law, be deemed
cumulative and not exclusive of any thereof or of any other powers and remedies
available to the Trustee or the holders of the Debentures, by judicial
proceedings or otherwise, to enforce the performance or observance of the
covenants and agreements contained in this Indenture, and no delay or omission
of the Trustee or of any holder of any of the Debentures to exercise any right
or power accruing upon any Event of Default occurring and continuing as
aforesaid shall impair any such right or power, or shall be construed to be a
waiver of any such default or any acquiescence therein; and, subject to the
provisions of Section 7.4, every power and remedy given by this Article VII or
by law to the Trustee or to the Debentureholders may be exercised from time to
time, and as often as shall be deemed expedient, by the Trustee or by the
Debentureholders.
    
     Section 7.7  Direction of Proceedings and Waiver of Defaults by Majority of
                  --------------------------------------------------------------
Debentureholders.  The holders of a majority in aggregate principal amount of
- ----------------                                                             
the Debentures at the time outstanding     

                                      -31-
<PAGE>
 
    
determined in accordance with Section 9.4 shall have the right to direct the
time, method and place of conducting any proceeding for any remedy available to
the Trustee or exercising any trust or power conferred on the Trustee; provided,
however, that (a) such direction shall not be in conflict with any rule of law 
         -----------------
or with this Indenture, and (b) the Trustee may take any other action deemed
proper by the Trustee which is not inconsistent with such direction.  The
holders of a majority in aggregate principal amount of the Debentures at the
time outstanding determined in accordance with Section 9.4 may on behalf of the
holders of all of the Debentures waive any past Event of Default hereunder and
its consequences except (i) a default in the payment of interest or premium, if
any, on, or the principal of, the Debentures, (ii) a failure by the Company to
exchange any Debentures into Exchange Property or (iii) a default in respect of
a covenant or provisions hereof which under Article XI cannot be modified or
amended without the consent of the holders of all Debentures then outstanding.
Upon any such waiver the Company, the Trustee and the holders of the Debentures
shall be restored to their former positions and rights hereunder; but no such
waiver shall extend to any subsequent or other Event of Default or impair any
right consequent thereon. Whenever any Event of Default hereunder shall have
been waived as permitted by this Section 7.7, said Event of Default shall for
all purposes of the Debentures and this Indenture be deemed to have been cured
and to be not continuing; but no such waiver shall extend to any subsequent or
other Event of Default or impair any right consequent thereon.     

     Section 7.8  Notice of Defaults.  The Trustee shall, within 90 days after
                  ------------------                                          
the occurrence of an Event of Default, mail to all Debentureholders, as the
names and addresses of such holders appear upon the registry books of the
Company, notice of all defaults known to a Responsible Officer, unless such
defaults shall have been cured or waived before the giving of such notice; and
provided that, except in the case of default in the payment of the principal of,
- --------                                                                        
or premium, if any, or interest on any of the Debentures, the Trustee shall be
protected in withholding such notice if and so long as a trust committee of
directors and/or Responsible Officers of the Trustee in good faith determine
that the withholding of such notice is in the interests of the Debentureholders.

     Section 7.9  Undertaking To Pay Costs.  All parties to this Indenture
                  ------------------------                                
agree, and each holder of any Debenture by his acceptance thereof shall be
deemed to have agreed, that any court may, in its discretion, require, in any
suit for the enforcement of any right or remedy under this Indenture, or in any
suit against the Trustee for any action taken or omitted by it as Trustee, the
filing by any party litigant in such suit of an undertaking to pay the costs of
such suit and that such court may in its discretion assess reasonable costs,
including reasonable attorneys' fees, against any party litigant in such suit,
having due regard to the merits and good faith of the claims or defenses made by
such party litigant; provided that the provisions of this Section 7.9 shall not
                     --------

Debentureholder, or group of Debentureholders, holding in the aggregate more
than ten percent in principal amount of the Debentures at the time outstanding
determined in accordance with Section 9.4, or to any suit instituted by any
Debentureholder for the enforcement of the payment of the principal of or
premium, if any, or interest on any Debenture on or after the due date expressed
in such Debenture or to any suit for the enforcement of the right to exchange
any Debenture in accordance with the provisions of Article XV.


                                 ARTICLE VIII.

                             CONCERNING THE TRUSTEE

     Section 8.1  Duties and Responsibilities of Trustee.  The Trustee, prior to
                  --------------------------------------                        
the occurrence of an Event of Default and after the curing of all Events of
Default which may have occurred, undertakes to perform such duties and only such
duties as are specifically set forth in this Indenture.  In case an Event of
Default has occurred (which has not been cured or waived) the Trustee shall
exercise such of the rights and powers vested in it by this Indenture, and use
the same degree of care and skill in their exercise, as a prudent man would
exercise or use under the circumstances in the conduct of his own affairs.

     No provision of this Indenture shall be construed to relieve the Trustee
from liability for its own negligent action, its own negligent failure to act or
its own willful misconduct, except that:

          (a)  prior to the occurrence of an Event of Default and after the
     curing or waiving of all Events of Default which may have occurred:

               (1)  the duties and obligations of the Trustee shall be
          determined solely by the express provisions of this Indenture and the
          Trust Indenture Act, and the Trustee shall not be liable except for
          the performance of such duties and obligations as are specifically set
          forth in this Indenture and no implied covenants or obligations shall
          be read into this Indenture and the Trust Indenture Act against the
          Trustee; and

               (2)  in the absence of bad faith on the part of the Trustee, the
          Trustee may conclusively rely, as to the truth of the statements and
          the correctness of the opinions expressed therein, upon any
          certificates or opinions furnished to the Trustee and conforming to
          the requirements of this Indenture; but, in the case of any such
          certificates or opinions which by any provisions hereof are
          specifically required to be furnished to the Trustee, the Trustee
          shall be under a duty to examine the

                                     -33-
<PAGE>

          same to determine whether or not they conform to the requirements of
          this Indenture;

          (b)  the Trustee shall not be liable for any error of judgment made in
     good faith by a Responsible Officer or Officers of the Trustee, unless it
     shall be provided that the Trustee was negligent in ascertaining the
     pertinent facts;

          (c)  the Trustee shall not be liable with respect to any action taken
     or omitted to be taken by it in good faith in accordance with the direction
     of the holders of not less than a majority in principal amount of the
     Debentures at the time outstanding determined as provided in Section 9.4
     relating to the time, method and place of conducting any proceeding for any
     remedy available to the Trustee, or exercising any trust or power conferred
     upon the Trustee, under this Indenture; and
    
          (d)  whether or not therein provided, every provision of this
     Indenture relating to the conduct or affecting the liability of, or
     affording protection to, the Trustee shall be subject to the provisions of
     this Section 8.1.     

          None of the provisions contained in this Indenture shall require the
Trustee to expend or risk its own funds or otherwise incur personal financial
liability in the performance of any of its duties or in the exercise of any of
its rights or powers, if there is reasonable ground for believing that the
repayment of such funds or adequate indemnity against such risk or liability is
not reasonably assured to it.

     Section 8.2  Reliance on Documents, Opinions, etc.  Except as otherwise
                  -------------------------------------                     
provided in Section 8.1:

          (a)  the Trustee may rely and shall be protected in acting upon any
     resolution, certificate, statement, instrument, opinion, report, notice,
     request, consent, order, bond, debenture, coupon or other paper or document
     believed by it in good faith to be genuine and to have been signed or
     presented by the proper party or parties;

          (b)  any request, direction, order or demand of the Company mentioned
     herein shall be sufficiently evidenced by an Officer's Certificate (unless
     other evidence in respect thereof be herein specifically prescribed); and
     any resolution of the Board of Directors may be evidenced to the Trustee by
     a copy thereof certified by the Secretary or an Assistant Secretary of the
     Company;

          (c)  the Trustee may consult with counsel and any advice or Opinion of
     Counsel shall be full and complete authorization and protection in respect
     of any action taken or omitted by it hereunder in good faith and in
     accordance with such advice or Opinion of Counsel;


                                     -34-
<PAGE>

          (d) the Trustee shall be under no obligation to exercise any of the
     rights or powers vested in it by this Indenture at the request, order or
     direction of any of the Debentureholders pursuant to the provisions of this
     Indenture, unless such Debentureholders shall have offered to the Trustee
     reasonable security or indemnity against the costs, expenses and
     liabilities which may be incurred therein or thereby;

          (e)  the Trustee shall not be bound to make any investigation into the
     facts or matters stated in any resolution, certificate, statement,
     instrument, opinion, report, notice, request, direction, consent, order,
     bond, debenture or other paper or document, but the Trustee, in its
     discretion, may make such further inquiry or investigation into such facts
     or matters as it may see fit, and, if the Trustee shall determine to make
     such further inquiry or investigation, it shall be entitled to examine the
     books, records and premises of the Company, personally or by agent or
     attorney; provided, however, that if the payment within a reasonable time
               -----------------                                              
     to the Trustee of the costs, expenses or liabilities likely to be incurred

     Section 8.5  Monies To Be Held in Trust.  Subject to the provisions of
                  --------------------------                               
Section 13.4, all monies received by the Trustee shall, until used or applied as
herein provided, be held in trust for the purposes for which they were received.
Money held by the Trustee in trust hereunder need not be segregated from other
funds except to the extent required by law.  The Trustee shall be under no
liability for interest on any money received by it hereunder except as may be
agreed from time to time by the Company and the Trustee.

     Section 8.6  Compensation and Expenses of Trustee.  The Company covenants
                  ------------------------------------                        
and agrees to pay to the Trustee from time to time, and the Trustee shall be
entitled to, reasonable compensation for all services rendered by it hereunder
in any capacity (which shall not be limited by any provision of law in regard to
the compensation of a trustee of an express trust), and the Company will pay or
reimburse the Trustee upon its request for all reasonable expenses,
disbursements and advances incurred or made by the Trustee in accordance with
any of the provisions of this Indenture (including the reasonable compensation
and the expenses and disbursements of its counsel and of all persons not
regularly in its employ) except any such expense, disbursement or advance as may
arise from its negligence or bad faith.  The Company also covenants to indemnify
the Trustee in any capacity under this Indenture and its agents and any
authenticating agent for, and to hold them harmless against, any loss, liability
or expense incurred without negligence or bad faith on the part of the Trustee
or such agent or authenticating agent, as the case may be, and arising out of or
in connection with the acceptance or administration of this trust or the
exercise or performance of any of its rights or powers or in any other capacity
hereunder, including the costs and expenses of defending themselves against any
claim of liability in the premises.  The obligations of the Company under this
Section 8.6 to compensate or indemnify the Trustee and to pay or reimburse the
Trustee for expenses, disbursements and advances shall be secured by a lien
prior to that of the Debentures upon all property and funds held or collected by
the Trustee as such, except funds held in trust for the benefit of the holders
of particular Debentures. The obligation of the Company under this Section shall
survive the satisfaction and discharge of this Indenture.

     When the Trustee and its agents and any authenticating agent incur expenses
or render services after an Event of Default specified in Section 7.1(f) or (g)
occurs, the expenses and the compensation for the services are intended to
constitute expenses of administration under any bankruptcy, insolvency or
similar laws.

provided in Section 8.1, whenever in the administration of the provisions of
this Indenture the Trustee shall deem it necessary or desirable that a matter be
proved or established prior to taking or omitting any action hereunder, such
matter (unless other evidence in respect thereof be herein specifically
prescribed) may, in the absence of negligence or bad faith on the


                                     -36-
<PAGE>

part of the Trustee, be deemed to be conclusively proved and established by an
Officer's Certificate delivered to the Trustee, and such Officer's Certificate,
in the absence of negligence or bad faith on the part of the Trustee, shall be
full warrant to the Trustee for any action taken or omitted by it under the
provisions of this Indenture upon the faith thereof.

     Section 8.8  Conflicting Interests of Trustee.  If the Trustee has or shall
                  --------------------------------                              
acquire a conflicting interest within the meaning of the Trust Indenture Act,

the manner provided by, and subject to the provisions of, the Trust Indenture
Act and this Indenture.

     Section 8.9  Eligibility of Trustee.  There shall at all times be a Trustee
                  ----------------------                                        
hereunder which shall be a Person that is eligible pursuant to the Trust
Indenture Act to act as such and has a combined capital and surplus of at least
$50,000,000.  If such Person publishes reports of condition at least annually,
pursuant to law or to the requirements of any supervising or examining
authority, then for the purposes of this Section, the combined capital and
surplus of such Person shall be deemed to be its combined capital and surplus as
set forth in its most recent report of condition so published.  If at any time
the Trustee shall cease to be eligible in accordance with the provisions of this
Section, it shall resign immediately in the manner and with the effect
hereinafter specified in this Article.

     Section 8.10  Resignation or Removal of Trustee.
                   --------------------------------- 

          (a)  The Trustee may at any time resign by giving written notice of
     such resignation to the Company and the Company shall mail, or cause to be
     mailed, notice thereof to the holders of Debentures at their addresses as
     they shall appear on the registry books of the Company.  Upon receiving
     such notice of resignation, the Company shall promptly appoint a successor
     trustee by written instrument, in duplicate, executed by order of the Board
     of Directors, one copy of which instrument shall be delivered to the
     resigning Trustee and one copy to the successor trustee.  If no successor
     trustee shall have been so appointed and have accepted appointment 60 days
     after the mailing of such notice of resignation to the Debentureholders,
     the resigning Trustee may petition any court of competent jurisdiction for
     the appointment of a successor trustee, or any Debentureholder who has been
     a bona fide holder of a Debenture or Debentures for at least six months
     may, subject to the provisions of Section 7.9, on behalf of himself and all
     others similarly situated, petition any such court for the appointment of a
     successor trustee.  Such court may thereupon, after such notice, if any, as
     it may deem proper and prescribe, appoint a successor trustee.

          (b)  In case at any time any of the following shall occur:


                                     -37-
<PAGE>

               (1)  the Trustee shall fail to comply with Section 8.8 after
          written request therefor by the Company or by any Debentureholder who
          has been a bona fide holder of a Debenture or Debentures for at least
          six months, or

               (2)  the Trustee shall cease to be eligible in accordance with
          the provisions of Section 8.9 and shall fail to resign after written
          request therefor by the Company or by any such Debentureholder, or

               (3)  the Trustee shall become incapable of acting, or shall be
          adjudged a bankrupt or insolvent, or a receiver of the Trustee or of
          its property shall be appointed, or any public officer shall take
          charge or control of the Trustee or of its property or affairs for the
          purpose of rehabilitation, conservation or liquidation,

     then, in any such case, the Company may remove the Trustee and appoint a
     successor trustee by written instrument, in duplicate, executed by order of
     the Board of Directors, one copy of which instrument shall be delivered to
     the Trustee so removed and one copy to the successor trustee, or, subject
     to the provisions of Section 7.9, any Debentureholder who has been a bona
     fide holder of a Debenture or Debentures for at least six months may, on
     behalf of himself and all others similarly situated, petition any court of
     competent jurisdiction for the removal of the Trustee and the appointment
     of a successor trustee.  Such court may thereupon, after such notice, if
     any, as it may deem proper and prescribe, remove the Trustee and appoint a
     successor trustee.

          (c)  The holders of a majority in aggregate principal amount of the
     Debentures at the time outstanding may at any time remove the Trustee and
     nominate a successor trustee which shall be deemed appointed as successor
     trustee unless within ten days after notice to the Company of such
     nomination the Company objects thereto, in which case the Trustee so
     removed or any Debentureholder, upon the terms and conditions and otherwise
     as in Section 8.10(a) provided, may petition any court of competent
     jurisdiction for an appointment of a successor trustee.

          (d)  Any resignation or removal of the Trustee and appointment of a
     successor trustee pursuant to any of the provisions of this Section 8.10
     shall become effective upon acceptance of appointment by the successor
     trustee as provided in Section 8.11.

     Section 8.11  Acceptance by Successor Trustee.  Any successor trustee
                   -------------------------------                        
appointed as provided in Section 8.10 shall execute, acknowledge and deliver to
the Company and to its predecessor trustee an instrument accepting such
appointment hereunder, and thereupon the resignation or removal of the
predecessor trustee


                                     -38-
<PAGE>

shall become effective and such successor trustee, without any further act, deed
or conveyance, shall become vested with all the rights, powers, duties and
obligations of its predecessor hereunder, with like effect as if originally
named as trustee herein; but, nevertheless, on the written request of the
Company or of the successor trustee, the trustee ceasing to act shall, upon
payment of any amounts then due it pursuant to the provisions of Section 8.6,
execute and deliver an instrument transferring to such successor trustee all the
rights and powers of the trustee so ceasing to act.  Upon request of any such
successor trustee, the Company shall execute any and all instruments in writing
for more fully and certainly vesting in and confirming to such successor trustee
all such rights and powers.  Any trustee ceasing to act shall, nevertheless,
retain a lien upon all property and funds held or collected by such trustee as
such, except for funds held in trust for the benefit of holders of particular
Debentures, to secure any amounts then due it pursuant to the provisions of
Section 8.6.

     No successor trustee shall accept appointment as provided in this Section
8.11 unless at the time of such acceptance such successor trustee shall be
qualified under the provisions of Section 8.8 and be eligible under the
provisions of Section 8.9.

     Upon acceptance of appointment by a successor trustee as provided in this
Section 8.11, the Company shall mail or cause to be mailed notice of the
succession of such trustee hereunder to the holders of Debentures at their
addresses as they shall appear on the registry books of the Company.  If the
Company fails to mail such notice within ten days after acceptance of
appointment by the successor trustee, the successor trustee shall cause such
notice to be mailed at the expense of the Company.

     Section 8.12   Succession by Merger, etc.  Any corporation into which the
                    --------------------------                                
Trustee may be merged or converted or with which it may be consolidated, or any
corporation resulting from any merger, conversion or consolidation to which the
Trustee shall be a party, or any corporation succeeding to all or substantially
all of the trust business of the Trustee, shall be the successor to the Trustee
hereunder without the execution or filing of any paper or any further act on the
part of any of the parties hereto, provided that such corporation shall be
                                   --------                               
qualified under the provisions of Section 8.8 and eligible under the provisions
of Section 8.9.

     In case any of the Debentures shall have been authenticated but not
delivered at the time such successor to the Trustee shall succeed to the trusts
created by this Indenture, any such successor to the Trustee may adopt the
certificate of authentication of any predecessor trustee or authenticating agent
appointed by such predecessor trustee, and deliver such Debentures so
authenticated; and in case at that time any of the Debentures shall not have
been authenticated, any successor to the Trustee or an authenticating agent
appointed by such successor trustee may authenticate such Debentures either in
the name of any predecessor trustee hereunder


                                     -39-
<PAGE>

or in the name of the successor trustee; and in all such cases such certificates
shall have the full force which it is anywhere in the Debentures or in this
Indenture provided that the certificate of the Trustee shall have; provided,
                                                                   ---------
however, that the right to adopt the certificate of authentication of any
- -------                                                                  
predecessor Trustee or authenticate Debentures in the name of any predecessor
Trustee shall apply only to its successor or successors by merger, conversion or
consolidation.

                   -------------------------------------------                  
Trustee shall be or become a creditor of the Company (or any other obligor upon
the Debentures), the Trustee shall be subject to the provisions of the Trust

                        CONCERNING THE DEBENTUREHOLDERS

     Section 9.1  Action by Debentureholders.  Whenever in this Indenture it is
                  --------------------------                                   
provided that the holders of a specified percentage in aggregate principal
amount of the Debentures may take any action (including the making of any demand
or request, the giving of any notice, consent or waiver or the taking of any
other action), the fact that at the time of taking any such action, the holders
of such specified percentage have joined therein may be evidenced (a) by any
instrument or any number of instruments of similar tenor executed by
Debentureholders in person or by agent or proxy appointed in writing, or (b) by
the record of the holders of Debentures voting in favor thereof at any meeting
of Debentureholders duly called and held in accordance with the provisions of
Article X, or (c) by a combination of such instrument or instruments and any
such record of such a meeting of Debentureholders. Whenever the Company or the
Trustee solicits the taking of any action by the holders of the Debentures, the
Company or the Trustee may fix in advance of such solicitation a date as the
record date for determining holders entitled to take such action.  The record
date shall be not more than 15 days prior to the date of commencement of
solicitation of such action.

     Section 9.2  Proof of Execution by Debentureholders.  Subject to the
                  --------------------------------------                 
provisions of Sections 8.1, 8.2 and 10.5, proof of the execution of any
instrument by a Debentureholder or his agent or proxy shall be sufficient if
made in accordance with such reasonable rules and regulations as may be
prescribed by the Trustee or in such manner as shall be satisfactory to the
Trustee.  The holding of Debentures shall be proved by the registry of such
Debentures or by a certificate of the Debenture registrar.

     The record of any Debentureholders' meeting shall be proved in the manner
provided in Section 10.6.

     Section 9.3  Who Are Deemed Absolute Owners.  The Company, the Trustee, any
                  ------------------------------                                
paying agent, the Exchange Agent and any Debenture registrar may deem the Person
in whose name such Debenture shall be registered upon the books of the Company
to be, and may treat him as, the absolute owner of such Debenture (whether or
not such Debenture shall be overdue and notwithstanding any notation of
ownership or other writing thereon) for the purpose of receiving payment of or
on account of the principal of, premium, if any, and interest on such Debenture,
for exchange of such Debenture and for all other purposes; and neither the
Company nor the Trustee nor any paying agent nor the Exchange Agent nor any
Debenture registrar shall be affected by any notice to the contrary.  All such
payments so made to any holder for the time being, or upon his order, shall be
valid, and, to the extent of the sum or sums so paid, effectual to satisfy and
discharge the liability for monies payable upon any such Debenture.

     Section 9.4  Company-Owned Debentures Disregarded.  In determining whether
                  ------------------------------------                         
the holders of the requisite aggregate principal amount of Debentures have
concurred in any direction, consent, waiver or other action under this
Indenture, Debentures which are owned by the Company or any other obligor on the
Debentures or by any Person directly or indirectly controlling or controlled by
or under direct or indirect common control with the Company or any other obligor
on the Debentures shall be disregarded and deemed not to be outstanding for the
purpose of any such determination; provided that for the purposes of determining
                                   --------                                     
whether the Trustee shall be protected in relying on any such direction,
consent, waiver or other action only Debentures which a Responsible Officer
knows are so owned shall be so disregarded.  Debentures so owned which have been
pledged in good faith may be regarded as outstanding for the purposes of this
Section 9.4 if the pledgee shall establish to the satisfaction of the Trustee
the pledgee's right to vote such Debentures and that the pledgee is not the
Company, any other obligor on the Debentures or a Person directly or indirectly
controlling or controlled by or under direct or indirect common control with the
Company or any such other obligor.  In the case of a dispute as to such right,
any decision by the Trustee taken upon the advice of counsel shall be full
protection to the Trustee. Upon request of the Trustee, the Company shall
furnish to the Trustee promptly an Officer's Certificate listing and identifying
all Debentures, if any, known by the Company to be owned or held by or for the
account of any of the above described Persons; and, subject to Section 8.1, the
Trustee shall be entitled to accept such Officer's Certificate as conclusive
evidence of the facts therein set forth and of the fact that all Debentures not
listed therein are outstanding for the purpose of any such determination.

     Section 9.5  Revocation of Consents; Future Holders Bound.  At any time
                  --------------------------------------------

9.1, of the taking of any action by the holders of the percentage in aggregate
principal amount of the Debentures specified in this Indenture in connection
with such action, any holder of a Debenture which is shown by the evidence to be
included


                                     -41-

in the Debentures the holders of which have consented to such action may, by
filing written notice with the Trustee at its Corporate Trust Office and upon
proof of holding as provided in Section 9.2, revoke such action so far as
concerns such Debenture. Except as aforesaid, any such action taken by the
holder of any Debenture shall be conclusive and binding upon such holder and
upon all future holders and owners of such Debenture and of any Debentures
issued in exchange or substitution therefor, irrespective of whether any
notation in regard thereto is made upon such Debenture or any Debenture issued
in substitution therefor.

that no vote shall be cast or counted at any meeting in respect of any Debenture
challenged as not outstanding and ruled by the chairman of the meeting to be not
outstanding.  The chairman of the meeting shall have no right to vote other than
by virtue of Debentures held by him or instruments in writing as aforesaid duly
designating him as the person to vote on behalf of other Debentureholders.  Any
meeting of Debentureholders duly called pursuant to the provisions of Section

meeting of Debentureholders shall be by written ballot on which shall be
subscribed the signatures of the holders of Debentures or of their
representatives by proxy and the principal amount of the Debentures held or
represented by them.  The permanent chairman of the meeting shall appoint two
inspectors of votes who shall count all votes cast at the meeting for or against
any resolution and who shall make and file with the secretary of the meeting
their verified written reports in duplicate of all votes cast at the meeting.  A
record in duplicate of the proceedings of each meeting of Debentureholders shall
be prepared by the secretary of the meeting and there shall be attached to said
record the original reports of the inspectors of votes on any vote by ballot
taken thereat and affidavits by one or more persons having knowledge of the
facts setting forth a copy of the notice of the meeting and showing that said
notice was mailed as provided in Section 10.2.  The record shall show the
principal amount of the Debentures voting in favor of or against any resolution.
The record shall be signed and verified by the affidavits of the permanent
chairman and secretary of the meeting and one of the duplicates shall be
delivered to the Company and the other to the Trustee to be preserved by the
Trustee, the latter to have attached thereto the ballots voted at the meeting.

     Any record so signed and verified shall be conclusive evidence of the
matters therein stated.

any right or rights conferred upon or reserved to the Trustee or to the
Debentureholders under any of the provisions of this Indenture or of the
Debentures.

     consider to be for the benefit of the holders of Debentures, and to make
     the occurrence, or the occurrence and continuance, of a default in any such
     additional covenants, restrictions or conditions an Event of Default
     permitting the enforcement of all or any of the several remedies provided
     in this Indenture as herein set forth; provided, however, that in respect
                                            -----------------                 
     of any such additional covenant, restriction or condition such supplemental
     indenture may provide for a particular period of grace after default (which
     period may be shorter or longer than that allowed in the case of other
     defaults) or may provide for an immediate enforcement upon such default or
     may limit the remedies available to the Trustee upon such default;

          (e)  to provide for the issuance under this Indenture of Debentures in
     coupon form (including Debentures registerable as to principal only) and to
     provide for substitution of such Debentures with the Debentures issued
     hereunder in fully registered form and to make all appropriate changes for
     such purpose;

          (f)  to cure any ambiguity or to correct or supplement any provision
     contained herein or in any supplemental indenture which may be defective or
     inconsistent with any other provision contained herein or in any
     supplemental indenture, or to make such other provisions in regard to
     matters or questions arising under this Indenture which shall not
     materially adversely affect the interests of the holders of the Debentures;

     to such extent as shall be necessary to effect the qualification of this
     Indenture under the Trust Indenture Act, or under any similar federal
     statute hereafter enacted.     

     The Trustee is hereby authorized to join with the Company in the execution
of any such supplemental indenture, to make any further appropriate agreements
and stipulations which may be therein contained and to accept the conveyance,
transfer and assignment of any property thereunder, but the Trustee shall not be
obligated to, but may in its discretion, enter into any supplemental indenture
which affects the Trustee's own rights, duties or immunities under this
Indenture or otherwise.

     Any supplemental indenture authorized by the provisions of this Section
11.1 may be executed by the Company and the Trustee without the consent of the
holders of any of the Debentures at the time outstanding, notwithstanding any of
the provisions of Section 11.2.

less than a majority in aggregate principal amount of the Debentures at the time
outstanding, the Company, when authorized by the resolutions of the Board of
Directors, and the Trustee may from time to time and at any time enter into an
indenture or indentures supplemental hereto for the purpose of adding any
provisions to or changing in any manner or eliminating any of the provisions of
this Indenture or any supplemental indenture or of modifying in any manner the
rights of the holders of the Debentures; provided, however, that no such
                                         -----------------              
supplemental indenture shall (i) extend the fixed maturity of any Debenture, or
reduce the rate or extend the time of payment of interest thereon, or reduce the
principal amount thereof or premium, if any, thereon, or reduce any amount
payable on redemption thereof, or impair or affect the right of any
Debentureholder to institute suit for the payment thereof, or make the principal
thereof or interest or premium, if any, thereon payable in any coin or currency
other than that provided in the Debentures, or modify the provisions of this
Indenture with respect to the subordination of the Debentures in a manner
adverse to the Debentureholders, or impair the right of the holders of 
Debentures to exchange the Debentures for Exchange Property or cause the 
repurchase of the Debentures subject to the terms set forth herein, including
Article XV, without the consent of the holder of each Debenture so affected, or
(ii) reduce the aforesaid percentage of Debentures, the holders of which are
required to consent to any such supplemental indenture, without the consent of
the holders of all Debentures then outstanding.

     Upon the request of the Company, accompanied by a copy of the resolutions
of the Board of Directors certified by its Secretary or Assistant Secretary
authorizing the execution of any such supplemental indenture, and upon the
filing with the Trustee of evidence of the consent of Debentureholders as
aforesaid, the Trustee shall join with the Company in the execution of such
supplemental indenture unless such supplemental indenture affects the Trustee's
own rights, duties or immunities under this Indenture or otherwise, in which
case the Trustee may in its discretion, but shall not be obligated to, enter
into such supplemental indenture.

     It shall not be necessary for the consent of the Debentureholders under
this Section 11.2 to approve the particular form of any proposed supplemental
indenture, but it shall be sufficient if such consent shall approve the
substance thereof.

     Section 11.3  Compliance with Trust Indenture Act; Effect of Supplemental

this Article XI shall comply with the Trust Indenture Act, as then in effect. 
Upon the execution of any supplemental indenture pursuant to the provisions of
this Article XI, this Indenture shall be and be deemed to be modified and
amended in accordance therewith and the respective rights, limitation of rights,
obligations, duties and immunities under this Indenture of the Trustee, the
Company and the holders of Debentures shall thereafter be determined, exercised
and enforced hereunder subject in all respects to such modifications and
amendments and all the terms and conditions of any such supplemental indenture
shall be and be deemed to be part of the terms and conditions of this Indenture
for any and all purposes.

delivered after the execution of any supplemental indenture pursuant to the
provisions of this Article XI may bear a notation in form approved by the
Trustee as to any matter provided for in such supplemental indenture.  If the
Company or the Trustee shall so determine, new Debentures so modified as to
conform, in the opinion of the Trustee and the Board of Directors, to any
modification of this Indenture contained in any such supplemental indenture may,
at the Company's expense, be prepared and executed by the Company, authenticated
by the Trustee (or an authenticating agent duly appointed by the Trustee
pursuant to Section 16.11) and delivered in substitution for the Debentures then
outstanding, upon surrender of such Debentures then outstanding.

               CONSOLIDATION, MERGER, SALE, CONVEYANCE AND LEASE
    
     Section 12.1  Company May Consolidate, etc. on Certain Terms. Subject to
                   ----------------------------------------------            
the provisions of Section 12.2, nothing contained in this Indenture or in any of
the Debentures shall prevent any consolidation or merger of the Company with or
into any other corporation or corporations (whether or not affiliated with the
Company), or successive consolidations or mergers in which the Company or any
successor shall be a party or parties, or shall prevent any sale, conveyance or
lease (or successive sales, conveyances or leases) of all or substantially all
of the property of the Company, to any other corporation (whether or not
affiliated with the Company), authorized to acquire and operate the same and
which shall be organized under the laws of any state of the United States or the
District of Columbia; provided, however, and the Company hereby covenants and
                      -----------------                                      
agrees, that upon any such consolidation, merger, sale, conveyance or lease: (i)
the due and punctual payment of the principal of and premium, if any, and 
interest on all of the Debentures, according to their tenor, and the due and 
punctual performance and observance of all of the covenants and conditions of 
this Indenture to be performed by the Company, shall be expressly assumed, by
supplemental indenture satisfactory in form to the Trustee, executed and
delivered to the Trustee by the corporation (if other than the Company) formed
by such consolidation, or into which the Company shall have been merged, or by
the corporation which shall have acquired or leased such property, and such
supplemental indenture shall provide for the applicable exchange rights and
repurchase rights set forth in Article XV, and (ii) no Event of Default shall 
have occurred and be continuing at the time of such transaction and immediately 
after giving effect to such transaction no Event of Default shall have occurred 
and be continuing.     

     Section 12.2  Successor Corporation To Be Substituted.  In case of any
                   ---------------------------------------                 
such consolidation, merger, sale, conveyance or lease and upon the assumption by
the successor corporation, by supplemental indenture, executed and delivered to
the Trustee and satisfactory in form to the Trustee, of the due and punctual
payment of the principal of and premium, if any, and interest on all of the
Debentures and the due and punctual performance of all of the covenants and
conditions of this Indenture to be performed by the Company, such successor
corporation shall succeed to and be substituted for the Company, with the same
effect as if it had been named herein as the party of the first part.  Such
successor corporation thereupon may cause to be signed, and may issue either in
its own name or in the name of McKesson Corporation, any or all of the
Debentures issuable hereunder which theretofore shall not have been signed by
the Company and delivered to the Trustee; and, upon the order of such successor
corporation instead of the Company and subject to all the terms, conditions and
limitations in this Indenture prescribed, the Trustee shall authenticate and
shall deliver, or cause to be authenticated and delivered, any Debentures which
previously shall have been signed and delivered by the officers of the Company
to the Trustee for authentication, and any Debentures which such successor
corporation thereafter shall cause


                                     -48-
<PAGE>

to be signed and delivered to the Trustee for that purpose.  All the Debentures
so issued shall in all respects have the same legal rank and benefit under this
Indenture as the Debentures theretofore or thereafter issued in accordance with
the terms of this Indenture as though all of such Debentures had been issued at
the date of the execution hereof.  In the event of any such consolidation,
merger, sale, conveyance or lease, the Person named as the "Company" in the
first paragraph of this Indenture or any successor which shall thereafter have
become such in the manner prescribed in this Article XII may be dissolved, wound
up and liquidated at any time thereafter and such Person shall be released from
its liabilities as obligor and maker of the Debentures and from its obligations
under this Indenture.

     In case of any such consolidation, merger, sale, conveyance or lease, such
changes in phraseology and form (but not in substance) may be made in the
Debentures thereafter to be issued as may be appropriate.

                   --------------------------------------
to Sections 8.1 and 8.2, shall receive an Officer's Certificate and an
Opinion of Counsel as conclusive evidence that any such consolidation, merger,
sale, conveyance or lease and any such assumption complies with the provisions
of this Article XII.

delivered) and not theretofore canceled, or (b) all the Debentures not
theretofore canceled or delivered to the Trustee for cancellation shall have
become due and payable, or are by their terms to become due and payable within
one year or are to be called for redemption within one year under arrangements
satisfactory to the Trustee for the giving of notice of redemption, or shall 
have been delivered to the Trustee for exchange or repurchase pursuant to

sufficient to pay at maturity or upon redemption of all of the Debentures 
(other than any Debentures which shall have been mutilated, destroyed, lost or
stolen and in lieu of or in substitution for which other Debentures shall have
been authenticated and delivered) not theretofore canceled or delivered to the
Trustee for cancellation, including principal and premium, if any, and interest
due or to become due to such date of maturity or redemption date, as the case 
may be, and if in either case the Company shall also pay or cause to be paid

redemption of which such monies have been deposited with the Trustee, of all
sums due and to become due thereon for principal and interest and premium, if
any.

Debentures, as the case may be, shall have become due and payable, shall be
repaid to the Company by the Trustee on demand and all liability of the Trustee
shall thereupon cease with respect to such monies; and the holder of any of the
Debentures shall thereafter look only to the Company for any payment which such
holder may be entitled to collect unless an applicable abandoned property law
designates another Person.

exchange, the holder of any Debenture to be exchanged shall surrender such
Debenture to the Exchange Agent for exchange by delivering such Debenture to, or
mailing such Debenture by registered mail, postage prepaid, addressed to the
Exchange Agent at the office or agency of the Company, maintained for that
purpose pursuant to Section 5.2 hereof, accompanied in each case by written
notice to the Company and the Exchange Agent that the holder elects to exchange
such Debenture, or, if less than the entire principal amount of such Debenture
is to be exchanged, the portion thereof to be exchanged.  Such notice shall also
state the name or names (with address) in which the certificate or certificates
for shares of Armor All Common Stock or, to the extent applicable, other
Exchange Property issuable upon such exchange shall be issued.  Debentures
surrendered for exchange shall be accompanied (if so required by the Company or
the Exchange Agent) by proper assignments thereof to the Company or in blank for
transfer; provided, however, that any Debenture surrendered for exchange during
          --------  -------
the period from the close of business on any record date for the payment of
interest through the close of business on the Business Day next preceding the
following interest payment date (unless it or the portion being exchanged shall
have been called for redemption on a date in such period) must be accompanied by
an amount, in funds acceptable to the Company, equal to the interest payable on
such interest payment date on the principal amount being exchanged.

      If the Company does not elect to deliver cash in lieu of Exchange
Property pursuant to Section 15.10, as promptly as practicable after the proper
surrender of such Debenture for exchange and in accordance with the procedures
set forth in the Exchange Agent Agreement (subject, however, to the following
paragraph of this Section 15.2), the Company shall or shall cause the Exchange
Agent to deliver to such holder, or on his written order a certificate or
certificates for the number of whole shares of Armor All Common Stock and/or
whole interests of any other Exchange Property deliverable upon exchange of such
Debenture (or specified portion thereof).  Such exchange shall be deemed to have
been effected immediately prior to the close of business on the date on which
such Debenture shall have been properly surrendered for exchange, which shall be
the date on which such Debenture and notice and any such required payment and
assignment shall be received by the Exchange Agent, and at such time the rights
of the holder of such Debenture as a Debentureholder shall cease and the


                                     -52-
<PAGE>

Person or Persons in whose name or names any certificate or certificates for
shares of Armor All Common Stock or other Exchange Property shall be deliverable
upon such exchange shall, as between such Person or Persons and the Company, be
deemed to have become the holder or holders of record of the shares or other
property represented thereby.
    
     Delivery of such certificate or certificates for shares of Armor All
Common Stock or other Exchange Property and of any check for any cash
apportioned thereto may be delayed for a reasonable period of time at the
request of the Company in order to effectuate the calculations of the
adjustments of the Armor All Common Stock or other Exchange Property or cash
apportioned thereto pursuant to this Article XV, to obtain any certificate
representing securities to be delivered, to complete any reapportionment of
the Armor All Common Stock or other Exchange Property or cash apportioned
thereto which is required by this Article XV or to comply with any applicable
law. If the Exchange Property includes securities and if, between the date an
exchange under this Section 15.2 is deemed effected and the date of delivery
of such securities, such securities shall cease to have any or certain rights,
or a record date or effective date of a transaction to which Section 15.4,
15.5 or 15.7 applies shall occur, the person entitled to receive such
securities shall be entitled only to receive such securities as so modified
and any dividends or proceeds received thereon on or after the date such
exchange is deemed effected and none of the Company, the Trustee and the
Exchange Agent shall be otherwise liable with respect to the modification of
such securities from the date such exchange is deemed effected and the date of
such delivery.     

     Except as otherwise expressly provided in this Article XV, no payment or
adjustment shall be made upon any exchange on account of any interest accrued on
the Debentures surrendered for exchange or on account of any dividends on the
Armor All Common Stock or other Exchange Property delivered upon such exchange;
                                                                               
provided, however, that interest accrued on any Debentures surrendered for
- -----------------                                                         
exchange on or after any Regular Record Date and before any Interest Payment
Date relating thereto shall be paid to, as applicable, the holder of record as
of such record date.

     In the case of any Debenture which is exchanged in part only, upon such
exchange the Company shall execute and the Trustee shall authenticate and
deliver to the holder thereof, at the expense of the Company, a new Debenture or
Debentures of authorized denominations in principal amount equal to the
unexchanged portion of such Debenture.
    
     Section 15.3  Fractional Interests.  No fractional shares of Armor All
                   --------------------                                    
Common Stock (or any form of fractional interest in      


                                     -53-
<PAGE>
 
    
any other security or property which is part of the Exchange Property) shall
be delivered upon exchanges of Debentures. If more than one Debenture shall be
surrendered for exchange at one time by the same holder, the number of whole
shares (or other integral units of such other securities or property), which
shall be delivered upon exchange shall be computed by the Company on the basis
of the aggregate principal amount of the Debentures (or specified portions
thereof to the extent permitted hereby) so surrendered. Instead of any
fractional interest which would otherwise be deliverable upon exchange of any
Debenture or Debentures (or specified portions thereof), the Exchange Agent on
behalf of the Company shall pay, on the date the exchange is deemed to be
effected, a cash adjustment in respect of such fractional interest in an
amount equal to the same fraction of the Market Price per share of the Armor
All Common Stock (or per unit of such other security or Exchange Property) on
the date of exchange. The Company shall authorize the Exchange Agent to obtain
the funds necessary, or anticipated by the Exchange Agent to be necessary, for
payment of such fractional interests by the sale of Armor All Common Stock or
other Exchange Property held by such Exchange Agent. Such amount of cash, if
any, resulting from such sale of Armor All Common Stock or other Exchange
Property and which is not necessary for the payment of such fractional
interests shall be held as Exchange Property for apportionment equally among
the other Exchange Property.

     Section 15.4  Adjustment of Exchange Price.
                   ---------------------------- 

          (a)  In the event Armor All shall (i) pay a dividend on Armor All
     Common Stock in shares of Armor All Common Stock, (ii) subdivide the
     outstanding shares of Armor All Common Stock into a greater number of
     shares of Armor All Common Stock, (iii) combine outstanding shares of Armor
     All Common Stock into a smaller number of shares of Armor All Common Stock,
     or (iv) issue, by reclassification of shares of Armor All Common Stock, any
     shares of its common stock (which in any such case shall apply to the
     shares of Armor All Common Stock held by the Exchange Agent under the
     Exchange Agent Agreement), the Exchange Price in effect immediately prior
     thereto shall be proportionately adjusted so that the holder of any
     Debentures thereafter surrendered for exchange shall be entitled (subject
     to Sections 15.9 and 15.10 hereof) to receive the number and kind of shares
     of Armor All Common Stock which such holder would have owned or have been
     entitled to receive after the happening of any of the events described
     above had such Debentures been exchanged immediately prior to the record
     date (or if there is no record date, the effective date) of such event.
     Such adjustments shall be made whenever any of the events listed above
     shall occur and shall become effective as of immediately after the close
     of business on the record date in the case of a stock dividend and shall
     become effective as of immediately after the close of business on the
          

                                      -54-
<PAGE>
 
    
     effective date in the case of a subdivision or combination or
     reclassification. Any holder surrendering any Debentures for exchange
     after such record date or such effective date, as the case may be, shall
     be entitled (subject to Section 15.10 hereof) to receive shares of Armor
     All Common Stock at the Exchange Price as so adjusted pursuant to this
     Section 15.4 and any other Exchange Property apportioned thereto.

          (b)  In the event some, but not all, of the shares of Armor All Common
     Stock otherwise deliverable upon exchange of the Debentures are tendered or
     exchanged and not withdrawn as of the last time (the "Expiration Time")
     tenders or exchanges may be made pursuant to a tender or exchange offer (as
     it shall have been amended) for shares of Armor All Common Stock, the
     Exchange Price in effect immediately prior to the Expiration Time shall be
     adjusted by multiplying such Exchange Price by a fraction, the numerator of
     which shall be the total number of shares of Armor All Common Stock then
     deliverable upon exchange of all outstanding Debentures (including any
     tendered or exchanged shares), and the denominator of which shall be the
     total number of shares of Armor All Common Stock then deliverable upon
     exchange of all outstanding Debentures less the number of shares so
     tendered or exchanged.  Such adjustments shall be made whenever the above
     shall occur and shall become effective as of immediately prior to the
     opening of business on the day following the Expiration Time.  Any holder
     surrendering any Debentures for exchange after the opening of business on
     the day following the Expiration Time shall be entitled (subject to Section
     15.10 hereof) to receive shares of Armor All Common Stock at the Exchange
     Price as so adjusted pursuant to this Section 15.4 and any other Exchange
     Property apportioned thereto.

          (c)  In the event any shares of Armor All Common Stock otherwise
     deliverable upon exchange of the Debentures are sold in a manner
     contemplated by Section 15.3, 15.5(d)(3) or 15.9 hereof, the Exchange Price
     in effect immediately prior to such sale shall be adjusted by multiplying
     such Exchange Price by a fraction, the numerator of which shall be the
     total number of shares of Armor All Common Stock then deliverable upon
     exchange of all outstanding Debentures (including any shares so sold), and
     the denominator of which shall be the total number of shares of Armor All
     Common Stock then deliverable upon exchange of all outstanding Debentures
     less the number of shares so sold.  Such adjustments shall be made whenever
     such sale shall occur and shall become effective as of immediately after
     the close of business on the date such shares are sold.  Any holder
     surrendering any Debentures for exchange after the close of business on
     the date such shares are sold shall be entitled (subject to Section 15.10
     hereof) to receive shares of Armor All Common Stock at the Exchange      

                                      -55-
<PAGE>
 
    
     Price as so adjusted pursuant to this Section 15.4 and any other Exchange
     Property apportioned thereto.

          Notwithstanding the foregoing, if any such sale pursuant to Section
     15.3, 15.5(d)(3) or 15.9 results in the sale of all of the shares of Armor
     All Common Stock previously held as Exchange Property, the Company shall
     execute and deliver to the Trustee a supplemental indenture (which shall
     conform to the Trust Indenture Act as in force at the date of execution of
     such supplemental indenture), and to the Exchange Agent a supplement to the
     Exchange Agent Agreement, each providing that the holder of each Debenture
     then outstanding shall have the right thereafter (subject to Sections 15.9
     and 15.10 hereof) to exchange such Debenture (i) for the amount of cash
     becoming Exchange Property as a result of such sale which is apportionable
     to the number of shares of Armor All Common Stock for which such Debenture
     was exchangeable immediately prior to such sale, and (ii) the other
     Exchange Property for which such Debenture was exchangeable immediately
     prior to such sale.  Such supplemental indenture shall provide for
     adjustments, and rights to receive and retain dividends or their
     equivalents, which shall be as nearly equivalent as may be practicable to
     the adjustments, and rights to receive and retain dividends or their
     equivalents, provided for in this Article 15.  Notice of such supplemental
     indenture shall as soon as practicable be filed with the Exchange Agent and
     mailed by or on behalf of the Company to the holders of Debentures at their
     last addresses as they shall appear on the Debenture register.  The Trustee
     shall not be under any responsibility to determine the correctness of any
     provisions contained in any such supplemental indenture relating either to
     the kind or amount of shares of stock or securities or property or cash
     receivable by the Debentureholders upon the exchange of their Debentures as
     herein provided after any such sale or to any adjustment to be made with
     respect thereto.

     Notwithstanding the foregoing provisions, no adjustment in the Exchange
Price shall be required unless such adjustment would require an increase or
decrease in such Exchange Price of more than 1%; provided, however, that any
                                                 -----------------          
adjustments which by reason of this paragraph are not required to be made shall
be carried forward and taken into account in any subsequent adjustment.  All
calculations under this Section 15.4 shall be made to the nearest one-ten
thousandth (0.0001) of a share or of an interest.

     Whenever the Exchange Price is adjusted as herein provided, the Company
shall determine the adjusted Exchange Price in accordance with this Section 15.4
and shall prepare an Officer's Certificate setting forth such adjusted
Exchange Price and any cash or other property apportioned to the Armor All
Common Stock and showing in detail the facts upon which such adjustment is 
     

                                      -56-
<PAGE>
 
    
based. Such certificate shall forthwith be filed with the Exchange Agent and
the Trustee, who may rely on such Officer's Certificate as conclusive evidence
of the correctness of the adjustment. A notice stating that the Exchange Price
has been adjusted and setting forth the adjusted Exchange Price and any cash
or other property apportioned to the Armor All Common Stock shall as soon as
practicable be mailed by or on behalf of the Company to the Debentureholders
at their last addresses as they shall appear upon the Debenture register.

     Section 15.5  Exchange Agent Agreement.
                   ------------------------ 

          (a)  The Company, simultaneously with the execution and delivery of
     this Indenture, is entering into the Exchange Agent Agreement with The
     First National Bank of Chicago, as Exchange Agent, pursuant to which the
     Company is depositing with the Exchange Agent _________ shares of Armor All
     Common Stock, which shall initially constitute the Exchange Property.  The
     Company shall deposit with the Exchange Agent from time to time such
     additional Exchange Property not already held by the Exchange Agent as the
     holders of all outstanding Debentures shall from time to time be entitled
     to receive (subject to Section 15.10) from the Exchange Agent pursuant to
     this Article 15 upon exchange thereof.

          (b)  All cash received by the Exchange Agent as herein provided will
     be invested upon written request of the Company by the Exchange Agent from
     time to time as so requested by the Company in U.S. Government Obligations
     pursuant to the Exchange Agent Agreement.  The Company shall be entitled to
     all cash dividends paid on the Exchange Property held by the Exchange Agent
     other than dividends paid pursuant to a plan of liquidation or partial
     liquidation or a recapitalization or restructuring or other extraordinary
     cash dividends, and shall be entitled to all interest payments on any debt
     securities included in the Exchange Property and any net income or gain on
     investment of cash made by the Exchange Agent pursuant to the Exchange
     Agent Agreement; provided, that if the Exchange Agent shall receive any
                      --------                                              
     such cash dividends or interest to which the Company is entitled pursuant
     hereto, the Exchange Agent shall not be required to transfer to the Company
     any such dividends or interest to which the Company is entitled pursuant
     hereto until receipt of an Officer's Certificate to the effect that the
     Company is entitled to such dividends or interest pursuant hereto.  The
     Exchange Agent shall hold and apply as hereinafter provided all other
     dividends paid on the Exchange Property held by the Exchange Agent under
     the Exchange Agent Agreement.

          (c) In case there shall be, at any time while any Debentures are
     outstanding, a nontaxable distribution of cash, securities or other
     property on Exchange Property,      

                                      -57-
<PAGE>
 
    
     including pursuant to a tender or exchange offer to which Section 15.4(b)
     applies (other than (i) cash dividends and interest paid on debt
     securities to which the Company is entitled, (ii) dividends,
     subdivisions, combinations and reclassifications for which an adjustment
     in the Exchange Price is made pursuant to Section 15.4(a) hereof, (iii)
     securities or other property received in a transaction to which Section
     15.7 hereof applies, and (iv) subscription rights, options, warrants or
     other similar rights to which paragraph (d) of this Section 15.5
     applies), the Company shall, as soon as reasonably practicable after its
     receipt thereof, notify the Exchange Agent of such receipt and promptly,
     and in any event within five business days of the receipt thereof,
     deposit with the Exchange Agent all such securities and other property
     pursuant to the Exchange Agent Agreement, and the Company shall either:

               (1)  instruct the Exchange Agent to sell any or all securities
          and other property so received by way of distribution for cash in such
          manner as the Company may instruct in writing; or

               (2)  instruct the Exchange Agent to retain and hold such
          securities and other property;

     and the proceeds, after payment of any taxes thereon pursuant to Section
     15.5(h) hereof, of any such sale and such securities or other property
     retained and held shall be additional Exchange Property for apportionment
     equally among other Exchange Property for which Debentures are exchangeable
     as of immediately after the close of business on the record date for the
     distribution to which this Section 15.5(c) applies, or, if there is no such
     record date, the effective date of such distribution (or, in the case of a
     tender or exchange offer to which Section 15.4(b) hereof applies, as of
     immediately prior to the opening of business on the day following the
     Expiration Time for such tender or exchange offer).

          (d)  In case there shall be, at any time while any Debentures are
     outstanding, a nontaxable distribution of any subscription rights, options,
     warrants or other similar rights with respect to any Exchange Property,
     including pursuant to a tender or exchange offer to which Section 15.4(b)
     hereof applies, the Company shall, as soon as reasonably practicable after
     its receipt thereof, notify the Exchange Agent of such receipt and
     promptly, and in any event within five business days of the receipt
     thereof, deposit with the Exchange Agent all such rights, pursuant to the
     Exchange Agent Agreement, and the Company shall either:      

                                      -58-
<PAGE>
 
    
               (1)  instruct the Exchange Agent to sell any rights so 
          distributed for cash in such manner as the Company may instruct in
          writing; or

               (2)  instruct the Exchange Agent to retain and hold such rights;
          provided that such rights shall not be allowed to expire unexercised
          --------                                                            
          so long as they are in the money and if otherwise feasible; or

               (3)  to the extent there is sufficient cash among the Exchange
          Property or to the extent the Company causes the sale of Exchange
          Property to provide sufficient cash, after provision for taxes, among
          the Exchange Property, instruct the Exchange Agent in writing to
          exercise any rights so distributed (with such amount of cash, if any,
          resulting from such sale and not necessary to exercise such rights
          being held as Exchange Property for apportionment equally among the
          other Exchange Property) and to thereafter either (i) retain and hold
          any securities and other property received upon exercise of such
          rights, (ii) cause the sale of some or all of such securities or other
          property received upon exercise of such rights, (iii) cause the pro
          rata distribution of such securities or other property received upon
          exercise of such rights to Debentureholders; or

               (4)  instruct the Exchange Agent to cause such rights to be
          distributed pro rata to the holders of record of Debentures on the
          Debenture register as of immediately after the close of business on
          the record date (and if there is no record date, the close of business
          on the effective date) for such distribution (or, in the case of a
          distribution pursuant to a tender or exchange offer to which Section
          15.4(b) hereof applies, as of immediately prior to the opening of
          business on the day following the Expiration Time for such tender or
          exchange offer);

     and, in the event option (1), (2) or (3) is chosen, the proceeds, after
     payment of any taxes thereon pursuant to Section 15.5(h) hereof, of any
     such sale and any such securities or other property retained and held shall
     be additional Exchange Property for apportionment equally among other
     Exchange Property for which Debentures are exchangeable as of immediately
     after the close of business on the record date for the distribution to
     which this Section 15.5(d) applies, or, if there is no such record date,
     the effective date of such distribution (or, in the case of a distribution
     pursuant to a tender or exchange offer to which Section 15.4(b) hereof
     applies, as of immediately prior to the opening of business on the day
     following the Expiration Time for such tender or exchange offer).

<PAGE>
 
    
          (e)  In case there shall be a distribution of cash on the Exchange 
     Property pursuant to a plan of liquidation or partial liquidation or a
     recapitalization or restructuring, or a payment of cash for Exchange
     Property pursuant to a tender or exchange offer to which Section 15.4(b)
     hereof applies, or other extraordinary cash dividend (other than a
     transaction to which Section 15.7 hereof applies), after payment of any
     taxes thereon pursuant to Section 15.5(h) hereof, the remainder of such
     dividend or distribution shall be held as Exchange Property for
     apportionment equally among other Exchange Property for which Debentures
     are exchangeable as of immediately after the close of business on the
     record date for such dividend or distribution to which this Section
     15.5(e) applies or, if there is no such record date, the effective date
     of such dividend or distribution (or, in the case of a tender or exchange
     offer to which Section 15.4(b) hereof applies, as of immediately prior to
     the opening of business on the day following the Expiration Time for such
     tender or exchange offer).

          (f)  In case there shall be, at any time while any Debentures are
     outstanding, a taxable distribution of securities or other noncash items of
     property (including subscription rights, options, warrants or other similar
     rights, and including securities or other property received in a tender or
     exchange offer to which Section 15.4(b) hereof applies, but excluding
     securities or other property received in a transaction to which Section
     15.7 hereof applies) with respect to any Exchange Property, the Company
     shall, as soon as reasonably practicable after its receipt thereof, notify
     the Exchange Agent of such receipt and promptly, and in any event within
     five (5) business days of the receipt thereof, deposit with the Exchange
     Agent all such property, pursuant to the Exchange Agent Agreement, and the
     Company shall instruct the Exchange Agent to sell such property so received
     by way of distribution for cash in such manner as the Company shall
     instruct in writing and the proceeds of such sale, after payment of taxes
     thereon pursuant to Section 15.5(h) hereof, shall be held as additional
     Exchange Property for apportionment equally among other Exchange Property
     for which Debentures are exchangeable as of immediately after the close of
     business on the record date for the distribution to which this Section
     15.5(f) applies, or, if there is no such record date, the effective date of
     such distribution (or, in the case of a tender or exchange offer to which
     Section 15.4(b) hereof applies, as of immediately prior to the opening of
     business on the day following the Expiration Time for such tender or
     exchange offer).

          (g)  Concurrently with any instruction to the Exchange Agent pursuant
     to subsections (c) or (d) of this Section 15.5, the Company shall deliver
     to the Exchange Agent an      

                                      -60-
<PAGE>
 
    
     Opinion of Counsel to the effect that the subject distribution is a
     nontaxable distribution.

          (h)  To the extent that the Company shall, within 10 days of its
     notification to the Exchange Agent of the Company's receipt of cash,
     securities or other property, including any rights, warrants or options,
     furnish the Exchange Agent with an Opinion of Counsel to the effect that a
     distribution to which Section 15.5(e) or (f) hereof applies or any sale of
     the securities, rights or other property received on such distribution or
     received on a distribution to which Section 15.5(c)(1), 15.5(d)(1) or
     15.5(d)(3) hereof applies is taxable to the Company or the Exchange Agent
     and an Officer's Certificate as to the amount of federal, state and local
     tax payable by the Company and the Exchange Agent as a result of a
     distribution to which Section 15.5(e) or (f) hereof applies and estimated
     to be payable as a result of any such sale (computed by the Company at the
     marginal tax rate applicable to such transaction), the Exchange Agent shall
     pay to, or to the order of the Company, in the case of taxes payable by the
     Company, or itself, in the case of taxes payable by it, from the cash
     received in such distribution to which Section 15.5(e) or (f) hereof
     applies, if any, or cash apportioned to the Armor All Common Stock or other
     Exchange Property hereunder or from the net cash proceeds received from any
     such sale, the amount of such tax as so computed by the Company.  In the
     case of taxes estimated to be payable as a result of any such sale, the
     Company shall deliver an Officer's Certificate within 10 days after
     completion of such sale stating the actual taxes payable as so computed and
     appropriate adjustment of such payments shall be made.  The remaining
     Exchange Property shall, in the case of a distribution to which Section
     15.5(e) or (f) applies, be apportioned equally among the other Exchange
     Property as of immediately after the close of business on the record date
     for such distribution, or, if there is no such record date, immediately
     after the close of business on the effective date of such distribution;
     provided, that in the case of a tender or exchange offer to which Section
     15.4(b) hereof applies, such apportionment shall be effected as of
     immediately prior to the opening of business on the day following the
     Expiration Time for such tender or exchange offer.  The remaining Exchange
     Property, in the case of a sale of securities, rights or other property
     received in a distribution to which Section 15.5(e) or (f) hereof applies,
     or a sale to which Section 15.5(c)(1), 15.5(d)(1) or 15.5(d)(3) hereof
     applies, shall be apportioned equally among the other Exchange Property as
     of immediately after the close of business on the effective date of such
     sale.  Any holder surrendering any Debentures after such record date or
     effective date or after the opening of business on the day following such
     Expiration Time, as the case may be,

     shall be entitled to receive (subject to Section 15.10 hereof) any Exchange
     Property apportioned thereto as so adjusted pursuant to this Article 15.

          (i)  In the event of any reduction of the principal amount of
     Debentures outstanding (other than as a result of surrender for exchange
     for Exchange Property), as evidenced by the delivery to the Trustee by the
     Company of Debentures for cancellation, the Company shall be entitled to
     the kind and amount of Exchange Property as shall at the time be in excess
     of the kind and amount of Exchange Property which would be required for the
     exchange of all Debentures then outstanding for the Exchange Property on
     the basis of the then applicable Exchange Price and the other terms and
     provisions of this Article 15 and the Exchange Agent Agreement.  Upon
     expiration of the right to surrender Debentures for exchange pursuant to
     this Article 15 and the Exchange Agent Agreement and when all other
     obligations of the Company shall have been satisfied under this Indenture
     and the Exchange Agent Agreement, the Company's obligation to exchange
     Debentures for Exchange Property or to pay cash in lieu thereof pursuant to
     Section 15.10 hereof shall be terminated and all cash and investments and
     other property held by the Exchange Agent under the Exchange Agent
     Agreement which are not required with respect to Debentures previously
     surrendered for exchange will, subject to the limitations contained in the
     Exchange Agent Agreement and subsection (j) below, be delivered by the
     Exchange Agent to the Company.

          (j)  The Exchange Agent shall not make any distribution of Exchange
     Property to the Company prior to the receipt by the Exchange Agent from the
     Company of an Officer's Certificate to the effect that no Event of Default
     exists hereunder and no event or condition which with notice or lapse of
     time or both would become such an Event of Default exists and which states
     in detail the basis asserted by the Company for such distribution.

          (k)  The Company shall be entitled to any net income or gain resulting
     from investments of cash made by the Exchange Agent pursuant to the
     Exchange Agent Agreement and shall reimburse the Exchange Agent for any
     losses realized in respect of such investments.

          (l)  The Company shall have the full and unqualified right and power
     to exercise any rights to vote, or to give consents or take any other
     action in respect of, the Armor All Common Stock or any other securities
     included in the Exchange Property at any time and the Exchange Agent shall
     have no duty to exercise any such rights. The Company shall not be liable
     to any holder of Debentures as a result of any vote, or failure to vote,
     consent or failure to consent, or any other act or failure to act taken by
     the      

                                      -62-

     Company in respect of the Armor All Common Stock or any other securities
     included in the Exchange Property.

          (m)  The obligations, covenants and agreements contained in the
     Exchange Agent Agreement shall not constitute obligations, covenants or
     agreements contained in this Indenture or any of the Debentures and neither
     the failure by the Company to observe any obligation, covenant or agreement
     contained in the Exchange Agent Agreement (unless such obligation, covenant
     or agreement shall also be contained in this Indenture) nor the failure of
     the Exchange Agent to fulfill any obligations, agreements or covenants set
     forth therein shall constitute (with or without the giving of notice, the
     passage of time or both) an Event of Default; provided, however, that
                                                   -----------------      
     nothing in this subsection shall impair the right of a holder to receive
     the Exchange Property apportioned to such holder's Debentures in exchange
     for such Debentures in accordance with the terms and conditions of this
     Article 15, subject to Section 15.10 hereof, and nothing in this subsection
     shall impair the rights and remedies of the Trustee and the holders under
     this Indenture with respect to a failure by the Company to observe its
     express agreements and covenants to cause the exchange of Debentures
     actually surrendered for exchange for Exchange Property apportioned thereto
     in accordance with the terms and conditions of this Article 15, subject to
     Section 15.10 hereof.

     Section 15.6  Company To Give Notice of Certain Events.  If at any time:
                   ----------------------------------------                  

          (a)  Armor All shall declare a dividend (or any other distribution) on
     the Armor All Common Stock or other Exchange Property which the Exchange
     Agent would be required to apply for the benefit of the holders of the
     Debentures in accordance with Section 15.5 hereof; or

          (b)  Armor All shall authorize the granting of subscription rights,
     options, warrants or other similar rights to holders of Armor All Common
     Stock or other Exchange Property; or

          (c)  there shall occur any reclassification of Armor All Common Stock
     (other than a subdivision or combination of outstanding shares of Armor All
     Common Stock) or any consolidation or merger to which Armor All is a party
     and for which approval of any stockholders of Armor All is required, or the
     sale or transfer of all or substantially all of the assets of Armor All; or

          (d)  there shall occur the voluntary or involuntary dissolution,
     liquidation or winding up of Armor All;      

                                      -63-

then the Company shall as promptly as practicable cause to be filed at each
office or agency maintained pursuant to this Indenture and cause to be mailed to
the holders of Debentures at their last addresses as they shall appear upon the
Debenture register, a notice stating (i) the date, if known by the Company, on
which a record is to be taken for the purpose of such dividend, distribution or
grant of rights, or, if a record is not to be taken, the date as of which the
holders of Armor All Common Stock of record to be entitled to such dividend or
distribution or grant of rights are to be determined, or (ii) the date, if known
by the Company, on which such reclassification, merger, consolidation, sale,
transfer, dissolution, liquidation or winding up is expected to become
effective, and the date as of which it is expected that holders of Armor All
Common Stock of record shall be entitled to exchange their shares of Armor All
Common Stock for securities or other property deliverable upon such
reclassification, consolidation, merger, sale, transfer, dissolution,
liquidation or winding up.

     Section 15.7  Merger of Armor All.  In case of any consolidation or merger

of Armor All with or into any other Person which results in shares of Armor All
Common Stock, as constituted prior to the consummation of such transaction,
being converted into other securities and/or property (including cash), or in
case of any sale or transfer of all or substantially all of the assets of Armor
All (if in connection with such sale or transfer holders of Armor All Common
Stock receive other securities and/or property including cash, in exchange for
their shares of Armor All Common Stock), or of any voluntary or involuntary
dissolution, liquidation or winding up of Armor All, the Company shall execute
and deliver to the Trustee a supplemental indenture (which shall conform to the
Trust Indenture Act as in force at the date of execution of such supplemental
indenture), and to the Exchange Agent a supplement to the Exchange Agent
Agreement, each providing that the holder of each Debenture then outstanding
shall have the right thereafter (subject to Sections 15.9 and 15.10 hereof) to
exchange such Debenture (i) for the kind and amount of securities and other
property receivable upon such consolidation, merger, sale, transfer,
dissolution, liquidation or winding up by a holder of the number of shares of
Armor All Common Stock for which such Debenture was exchangeable immediately
prior to such consolidation, merger, sale, transfer, dissolution, liquidation or
winding up and (ii) the other Exchange Property for which such Debenture was
exchangeable immediately prior to such consolidation, merger, sale, transfer,
dissolution, liquidation or winding up.  Such supplemental indenture shall
provide for adjustments, and rights to receive and retain dividends or their
equivalents, which shall be as nearly equivalent as may be practicable to the
adjustments, and rights to receive and retain dividends or their equivalents,
provided for in this Article 15.  The above provisions of this Section 15.7
shall similarly apply to any successive      

                                      -64-
<PAGE>
 
    
consolidation, merger, sale, transfers, dissolution, liquidation or winding up.

     Notice of such supplemental indenture shall as soon as practicable be filed
with the Exchange Agent and mailed by or on behalf of the Company to the holders
of Debentures at their last addresses as they shall appear on the Debenture
register.

     The Trustee shall not be under any responsibility to determine the
correctness of any provisions contained in any such supplemental indenture
relating either to the kind or amount of shares of stock or securities or
property or cash receivable by the Debentureholders upon the exchange of their
Debentures as herein provided after any such consolidation, merger, sale,
transfer, dissolution, liquidation or winding up or to any adjustment to be made
with respect thereto.

     Section 15.8  Certain Tender or Exchange Offers for Exchange Property.
                   ------------------------------------------------------- 

          (a)  In the event of a tender offer or exchange offer for any class of
     securities included within the Exchange Property (i) if the Company owns
     securities of such class which are not Exchange Property, the Company will
     cause the Exchange Agent to tender such securities of such class in the
     same proportion that the Company tenders its securities in such class which
     are not Exchange Property, and (ii) if the only securities of such class
     which the Company owns are Exchange Property, the Company may, at its
     option and in its sole discretion, elect to cause the Exchange Agent to
     tender all or any portion or none of such securities; provided, that,
                                                           --------       
     notwithstanding any other provision of this Section 15.8(a), in the case of
     a tender offer or exchange offer made by the Company or any affiliate of
     the Company (as such term is defined in Rule 12b-2 under the Exchange Act),
     the Company will not cause the Exchange Agent to tender any such securities
     included within the Exchange Property unless a majority of such securities
     that are held by persons other than the Company or any affiliate of the
     Company have been tendered and not withdrawn pursuant to such tender or
     exchange offer as of immediately prior to the Expiration Time.  The
     proceeds of the sale, after payment of any taxes thereon, of any such
     Exchange Property pursuant to any such tender or exchange offer will be
     held by the Exchange Agent as Exchange Property for apportionment equally
     among the other Exchange Property, except that the Company shall be
     entitled to any interest earned or dividends paid thereon.

          (b)  If, as a result of any tender or exchange offer, all shares of
     Armor All Common Stock then constituting Exchange Property shall have been
     sold or exchanged pursuant to such offer, the Company shall execute and
     deliver to the Trustee a supplemental indenture (which      

                                      -65-
<PAGE>
 
    
     shall conform to the Trust Indenture Act as in force at the date of
     execution of such supplemental indenture), and to the Exchange Agent a
     supplement to the Exchange Agent Agreement, each providing that the holder
     of each Debenture then outstanding shall have the right thereafter (subject
     to Sections 15.9 and 15.10 hereof) to exchange such Debenture (i) for the
     kind and amount of securities and other property receivable upon such
     tender or exchange by a holder of the number of shares of Armor All Common
     Stock for which such Debenture was exchangeable immediately prior to the
     Expiration Time of such tender or exchange, and (ii) the other Exchange
     Property for which such Debenture was exchangeable immediately prior to the
     Expiration Time of such tender or exchange.  Such supplemental indenture
     shall provide for adjustments, and rights to receive and retain dividends
     or their equivalents, which shall be as nearly equivalent as may be
     practicable to the adjustments, rights to receive and retain dividends or
     their equivalents, provided for in this Article 15.  The above provisions
     of this Section 15.8 shall similarly apply to any successive tender or
     exchange offer.

          Notice of such supplemental indenture shall as soon as practicable be
     filed with the Exchange Agent and mailed by or on behalf of the Company to
     the holders of Debentures at their last addresses as they shall appear on
     the Debenture register.

          The Trustee shall not be under any responsibility to determine the
     correctness of any provisions contained in any such supplemental indenture
     relating either to the kind or amount of shares of stock or securities or
     property or cash receivable by the Debentureholders upon the exchange of
     their Debentures as herein provided after any such tender or exchange or to
     any adjustment to be made with respect thereto.

     Section 15.9  Tax Adjustments in Exchange Price.  If an event shall occur
                   ---------------------------------                          
which causes the Exchange Price to be subject to adjustment pursuant to Section
15.4 hereof, or a merger, consolidation or sale or transfer of assets or of any
voluntary or involuntary dissolution, liquidation or winding up of Armor All
shall occur requiring a supplemental indenture under Section 15.7 hereof, or if
a tender or exchange offer requiring a supplemental indenture under Section
15.8(b) hereof shall occur, and if, within 10 days after the effective date or
Expiration Time of such transaction (as the case may be), the Company shall
furnish the Exchange Agent with an Opinion of Counsel to the effect that such
transaction is taxable to the Company or the Exchange Agent and an Officer's
Certificate as to the amount of federal, state and local tax payable by the
Company or the Exchange Agent as a result of such transaction (computed by the
Company at the marginal tax rate applicable to such transaction), the Exchange
Agent shall pay to, or to the order

of, the Company, in the case of taxes payable by the Company, or itself, in the
case of taxes payable by it, the cash held by it and apportioned or to be
apportioned to the Exchange Property for which outstanding Debentures are
exchangeable, up to the amount of such taxes.  In the event that the cash held
by the Exchange Agent and so apportioned or to be apportioned is insufficient to
pay to the Company or the Exchange Agent the amount of such taxes, the Exchange
Agent shall, as soon as reasonably practicable and to the extent legally
permissible, sell in accordance with written instructions received from the
Company, or if no such instructions are received, as determined by the Exchange
Agent, such Exchange Property (including any securities or other property
included therein) as may be necessary to pay, from the proceeds thereof after
payment of any taxes by the Company or the Exchange Agent on such sale, the
amount of any such insufficiency.  Such amount of cash, if any, resulting from
such sale of Exchange Property and which is not necessary to pay the amount of
such insufficiency shall be held as Exchange Property for apportionment equally
among other Exchange Property.  The Exchange Agent shall notify the Company and
the Trustee of any such sale and the Exchange Property sold.  Following payment
of all necessary amounts to the Company or the Exchange Agent, such Exchange
Property held by the Exchange Agent shall be proportionately adjusted so as to
be apportioned equally to the Debentures outstanding as of immediately after the
close of business on the record date or the effective date for the transaction
to which this section applies (as shall be specified in Section 15.4 or 15.7
hereof, if and as applicable) or as of immediately prior to the opening of
business on the day following the Expiration Time for the tender or exchange
offer to which this section applies (as specified in Section 15.8(b) hereof), as
the case may be.  Any holder surrendering any Debentures for exchange after such
adjustment shall be entitled (subject to Section 15.10 hereof) to receive the
Exchange Property as so adjusted pursuant to this paragraph.  If this Section
15.9 shall apply to a transaction and the sale by the Company of the
consideration receivable therein shall not be legally permissible and the amount
of cash among the Exchange Property shall not be sufficient to pay all taxes
payable by the Company or the Exchange Agent which arise from such transaction,
the Company may direct the Exchange Agent to segregate for the benefit of the
Company or the Exchange Agent or deliver to the Company or the Exchange Agent an
amount of Exchange Property theretofore held by the Exchange Agent having a
Market Price equal to the unsatisfied portion of the tax payable by the Company
or the Exchange Agent with respect to such transaction including any tax payable
upon the delivery or sale thereof in order to satisfy the aforementioned tax,
and such Exchange Property shall thereafter be solely for the account of the
Company or the Exchange Agent, as the case may be, and holders of Debentures
shall have no rights thereto.

     In the event that an Opinion of Counsel given pursuant to this Indenture
concludes that whether taxes are payable by the      

                                      -67-
<PAGE>
 
    
Company or the Exchange Agent is uncertain under the then state of the law or
facts or both, the Company shall have the option of requesting the Exchange
Agent to segregate the amount of funds that would be payable (or securities or
other property in lieu thereof), if such taxes were deemed payable, together
with the amount estimated in good faith to be the reasonable costs and expenses
(including attorneys' fees) of obtaining a determination as set forth below.
The holders shall have no rights to such funds or securities or other property,
which shall be held by the Exchange Agent for the Company (or itself, as the
case may be), and the Exchange Property deliverable upon exchange of Debentures
pursuant to this Article 15 shall be reapportioned as though such segregated
amounts had been paid to the Company or the Exchange Agent for such taxes, and
any holder surrendering any Debenture for exchange after the record or effective
date (or, in the case of tender or exchange offers, after the opening of
business on the day following the applicable Expiration Time) of the applicable
transaction giving rise to an adjustment pursuant to this Section 15.9
immediately shall be entitled (subject to Section 15.10 hereof) to receive only
such Exchange Property upon exchange of Debentures pursuant to this Article 15
as so reapportioned.  The Company shall thereupon in good faith seek an
appropriate determination from the appropriate agencies and, if judged necessary
by the Company in good faith, from appropriate courts, as to whether taxes are
so payable.  If an appropriate determination is made that such taxes are so
payable, then the Exchange Agent shall immediately pay the funds or deliver the
securities or other property so segregated to the Company (or, if taxes are
payable by the Exchange Agent, retain such funds or securities or other property
for itself), and if an appropriate determination is made that such taxes are not
payable or an amount of tax is payable which is less than the amount of funds or
property so segregated, then the Exchange Agent, after paying to the Company (or
itself, as the case may be) out of such funds or securities or other property
the reasonable expenses and costs (including attorneys' fees) of obtaining such
determination (and any taxes so payable), shall apportion such remaining funds
or securities or other property which had been so segregated among the Exchange
Property as of immediately after the close of business on the record date or the
effective date of such transaction giving rise to an adjustment pursuant to
Section 15.4 or 15.7 hereof, or as of immediately prior to the opening of
business on the day after the Expiration Time for the tender or exchange offer
giving rise to an adjustment, whichever is applicable.  If any Debenture has
been exchanged on or after such record date or effective date or after the
opening of business on the day after such Expiration Time, as the case may be,
and before a determination is made that no taxes are payable or an amount of tax
is payable which is less than the amount of funds or securities or other
property so segregated, the Company to the extent not previously delivered,
shall deliver such Exchange Property as reapportioned following such
determination, to the      

                                      -68-

Person to which and in the manner in which the other proceeds of the exchange of
such Debenture were delivered.

     Section 15.10  Cash Equivalent.  Notwithstanding any other provisions in

this Article 15, in lieu of delivering certificates representing shares of Armor
All Common Stock or other Exchange Property in exchange for Debentures
surrendered in accordance with Section 15.2 hereof, the Company may, at the
Company's option, pay to the holder surrendering such Debentures an amount in
cash equal to the value of the Exchange Property for which such Debentures are
exchangeable (based on the Market Price as calculated on the date of receipt by
the Exchange Agent of the notice of exchange delivered by such holder).  Prior
to so directing the Exchange Agent to make any such cash payment, the Company
shall deposit with the Exchange Agent the cash so payable.

     Section 15.11  Repurchase Rights.  In the event that the Company obtains or
                    -----------------                                           
otherwise releases any Armor All Common Stock or other Exchange Property in any
manner otherwise than as contemplated by Section 15.12(a) hereof, each holder
will have the right ("Repurchase Right"), at such holder's option, to require
the Company to purchase for cash all of such holder's Debentures, or a portion
thereof which is $1,000 or any integral multiple thereof, in the manner and at
the price described below.

     Promptly (and in any event within 10 days) after the Company has obtained
or released any Armor All Common Stock or any other Exchange Property in any
manner otherwise than as contemplated by Section 15.12(a) hereof, the Exchange
Agent will mail to all holders of record of Debentures a notice thereof and the
Repurchase Right arising as a result thereof (a "Repurchase Notice").  To
exercise the Repurchase Right, a Debentureholder must deliver on or before the
20th Business Day after the date of the Repurchase Notice written notice to the
Exchange Agent of the holder's exercise of such right, together with the
Debentures with respect to which the right is being exercised, duly endorsed for
transfer.

     Promptly after the expiration of the period in which a Debentureholder may
exercise the Repurchase Right (the "Repurchase Date") pursuant to this Section
15.11, the Company will be required to repurchase all Debentures in respect of
which the Repurchase Right has been exercised at the following repurchase
prices:  (i) if the date on which the Exchange Property was obtained or released
in a manner not contemplated by Section 15.12(a) hereof (the "Triggering Date")
is before February 16, 1999, the repurchase price shall be 120% of the greater
of (a) the principal amount of such Debentures (plus accrued and unpaid
interest, if any, to the Repurchase Date) and (b) the Market Price of the
Exchange Property deliverable in exchange for such Debentures on the Triggering
Date (or if such date is not a Business Day, on the next succeeding Business
     

                                      -69-
<PAGE>
 
    
Day); and (ii) if the Triggering Date occurs on or after February 16, 1999, the
repurchase price shall be the greater of (a) the redemption price on the
Triggering Date and (b) the Market Price of the Exchange Property deliverable in
exchange for such Debentures on the Triggering Date (or if such date is not a
Business Day, on the next succeeding Business Day).

     The obligation of the Company to deliver Exchange Property (or cash in lieu
thereof) in exchange for Debentures shall survive and continue to apply in full
force and effect following and notwithstanding the occurrence of any event
triggering a Repurchase Right.  Failure by the Company to exchange Debentures in
accordance with this Indenture or to repurchase Debentures upon exercise of a
Repurchase Right will constitute an Event of Default with respect to the
Debentures and holders of Debentures will have the remedies provided for in the
Indenture, including acceleration of the indebtedness evidenced by the
Debentures, in the event of any such failure.

     If an offer is made to repurchase Debentures in connection with a
Repurchase Right, the Company will comply with all tender offer rules, including
but not limited to Sections 13(e), 14(d) and 14(e) under the Exchange Act and
Rules 13e-1, 13e-4 and 14e-1 thereunder, to the extent applicable to such offer
(including any applicable withdrawal rights).

          (a)  The Company shall be entitled, out of the Armor All Common Stock
     or other Exchange Property, to such kind and quantity of Exchange Property
     as shall be in excess of the quantity of Exchange Property held by the
     Exchange Agent which would be deliverable by the Exchange Agent upon the
     exchange of all Debentures then outstanding, and such excess shall be held
     by the Exchange Agent for the account of the Company and, upon delivery of
     the Officer's Certificate provided for in the following sentence, released
     to the Company upon demand.  Upon demand of any withdrawal of Exchange
     Property from the Exchange Agent, the Company shall deliver to the Trustee
     an Officer's Certificate (and a copy thereof to the Exchange Agent) which
     shall state (i) the principal amount of Debentures then outstanding and the

     thereof upon exchange, (ii) that the withdrawal of the kind and amount of
     Exchange Property referred to in such demand is permitted by the provisions
     of this Indenture and (iii) that the Exchange Property so to be withdrawn
     would not be deliverable upon exchange of all Debentures then outstanding.
     In delivering such certificate, the Company may rely on information
     furnished to it by the Exchange Agent as to the kind and amount of Exchange
     Property held by it and the kind and amount thereof previously delivered to
     holders of Debentures.

such adjustment when made, or with respect to the method employed, or herein or
in any supplemental indenture provided to be employed, in making the same.
Neither the Trustee nor the Exchange Agent shall be accountable with respect to

be outstanding and exchangeable for Armor All Common Stock or other Exchange
Property pursuant to this Article 15, the Company shall (i) preserve unimpaired
the right of each holder of Debentures, upon exchange thereof, to receive shares
of Armor All Common Stock or other Exchange Property as such holder shall from
time to time be entitled to receive in accordance with the provisions of this
Article 15, and (ii) not pledge, mortgage, hypothecate or grant a security
interest in, or permit any mortgage, pledge, security interest or other lien
upon, the Exchange Property.

     Section 15.15  Transfer Taxes.  The Company will pay any and all taxes that
                    --------------                                              
may be payable in respect of the transfer and delivery of shares of Armor All
Common Stock (or other securities included in the Exchange Property) pursuant
hereto, other than income, capital gains and similar taxes imposed on any holder

                                                           -----------------

respect of any transfer involved in the delivery, upon an exchange of
Debentures, of shares of Armor All Common Stock (or other securities included in
the Exchange Property) in a name other than that in which the Debentures so
exchanged were registered, and no such transfer shall be made unless and until
the Person      

                                      -71-
<PAGE>
 
    
requesting such transfer has paid to the Company or the applicable Exchange
Agent the amount of any such tax, or has established to the satisfaction of the
Company and such Exchange Agent that such tax has been paid.

     Section 15.16  Fully Paid Shares.  The Company warrants and covenants that
                    -----------------                                          
all shares of Armor All Common Stock delivered upon the exchange of Debentures
will be fully paid and nonassessable and that each holder of Debentures who
receives shares of Armor All Common Stock or other Exchange Property in exchange
for his Debentures, pursuant to this Article 15, will receive valid and
marketable title to such Exchange Property, free and clear of all claims, liens
and encumbrances.

     Section 15.17  Cancellation of Debentures.  All Debentures delivered for
                    --------------------------

provided in Section 2.8 of this Indenture.

     Section 15.18  Registration of Armor All Common Stock and Other Securities
                    -----------------------------------------------------------
Held as Exchange Property.  The Company hereby covenants that so long as

Debentures remain outstanding which may be exchanged for shares of Armor All
Common Stock held by the Exchange Agent pursuant to the Exchange Agent
Agreement, it will use its best efforts to cause to be maintained an effective
registration statement on file with the Commission covering the delivery of such
Armor All Common Stock, and any qualification under state blue sky or securities
laws required for such delivery will also be maintained.

     If, pursuant to the transactions described in Sections 15.5, 15.7 and 15.8
hereof, Exchange Property includes securities which, in the opinion of counsel
for the Company, may not be delivered in exchange for Debentures without
registration under the Securities Act, the Company shall cause such securities
to be so registered as promptly as practicable, except that in the absence of
such registration, the Company may, at its option, deliver cash in lieu of such
securities in the manner provided in Section 15.10 hereof and such cash payment
may be made solely with respect to such securities.

the Trustee shall promptly appoint a successor authenticating agent (which may
be the Trustee), shall give written notice of such appointment to the Company
and shall mail notice of such appointment to all holders of Debentures as the
names and addresses of such holders appear on the Debenture register.

     The Trustee agrees to pay to the authenticating agent from time to time
reasonable compensation for its services, and the Trustee shall be entitled to
be reimbursed for such payments, subject to Section 8.6.

     The provisions of Sections 8.2, 8.3, 8.4, 9.3 and this Section 16.11 shall
be applicable to any authenticating agent.

     Section 16.12  Execution in Counterparts.  This Indenture may be executed

                         [FORM OF REVERSE OF DEBENTURE]

                              McKESSON CORPORATION
                             A Delaware Corporation

              ______% Exchangeable Subordinated Debenture Due 2004

     This Debenture is one of a duly authorized issue of Debentures of the
Company, designated as its _____% Exchangeable Subordinated Debentures Due 2004
(herein called the "Debentures"), limited to the aggregate principal amount of
$155,000,000 all issued or to be issued under and pursuant to an Indenture dated
as of __________, 1994 (herein called the "Indenture"), between the Company and
The First National Bank of Chicago (herein called the "Trustee"), to which
Indenture and all indentures supplemental thereto reference is hereby made for a
description of the rights, limitations of rights, obligations, duties and
immunities thereunder of the Trustee, the Company and the holders of the
Debentures.

     In case an Event of Default, as defined in the Indenture, shall have
occurred and be continuing, the principal of and accrued interest on all
Debentures may be declared, and upon said declaration shall become, due and
payable, in the manner, with the effect and subject to the conditions provided
in the Indenture.

     In the case of certain events, holders of Debentures shall have a 
Repurchase Right, as defined in the Indenture, to cause the Company to 
repurchase such Debentures on the terms and subject to the conditions provided 
in the Indenture.

     The Indenture contains provisions permitting the Company and the Trustee,
with the consent of the holders of not less than a majority in aggregate
principal amount of the Debentures at the time outstanding, evidenced as in the
Indenture provided,

                                      -3-

to execute supplemental indentures adding any provisions to or changing in any
manner or eliminating any of the provisions of the Indenture or of any
supplemental indenture or modifying in any manner the rights of the holders of
the Debentures; provided, however, that no such supplemental indenture shall (i)
                -----------------                                               
extend the fixed maturity of any Debenture, or reduce the rate or extend the
time of payment of interest thereon, or reduce the principal amount thereof or
premium, if any, thereon, or reduce any amount payable on redemption thereof, or
impair or affect the right of any Debentureholder to institute suit for the
payment thereof, or make the principal thereof or interest or premium, if any,
thereon payable in any coin or currency other than that provided in the
Debentures, or modify the provisions of the Indenture with respect to the
subordination of the Debentures in a manner adverse to the Debentureholders, or
impair the right to exchange the Debentures into Exchange Property or impair the
right of the holders of the Debentures to cause the repurchase thereof, in each 
case subject to the terms set forth in the Indenture, including Article 15
thereof, without the consent of the holder of each Debenture so affected, or
(ii) reduce the aforesaid percentage of Debentures, the holders of which are
required to consent to any such supplemental indenture, without the consent of
the holders of all Debentures then outstanding. It is also provided in the
Indenture that, prior to any declaration accelerating the maturity of the
Debentures, the holders of a majority in aggregate principal amount of the
Debentures at the time outstanding may on behalf of the holders of all of the
Debentures waive any past default or Event of Default under the Indenture and
its consequences except a default in the payment of interest or any premium on
or the principal of any of the Debentures or a default in respect of a covenant
or provision of the Indenture which under Article 11 thereof cannot be modified
or amended without the consent of the holders of all Debentures then
outstanding.  Any such consent or waiver by the holder of this Debenture (unless
revoked as provided in the Indenture) shall be conclusive and binding upon such
holder and upon all future holders and owners of this Debenture and any
Debentures which may be issued in substitution hereof, irrespective of whether
or not any notation thereof is made upon this Debenture or such other
Debentures.     

     The indebtedness evidenced by the Debentures is, to the extent and in the
manner provided in the Indenture, expressly subordinate and subject in right of
payment to the prior payment in full of all Senior Indebtedness of the Company,
as defined in the Indenture, whether outstanding at the date of the Indenture or
thereafter incurred, and this Debenture is issued subject to the provisions of
the Indenture with respect to such subordination.  Each holder of this
Debenture, by accepting the same, agrees to and shall be bound by such
provisions and authorizes the Trustee on his behalf to take such action as may
be necessary or appropriate to effectuate the subordination so provided and
appoints the Trustee his attorney-in-fact for such purpose.

     No reference herein to the Indenture and no provision of this Debenture or
of the Indenture shall alter or impair the obligation of the Company, which is
absolute and unconditional, to pay the principal of and any premium and interest
on this Debenture at the place, at the respective times, at the rate and in the
coin or currency herein prescribed.

     Interest on the Debentures shall be computed on the basis of a year of
twelve 30-day months.

     The Debentures are issuable in registered form without coupons in
denominations of $1,000 and any integral multiple of $1,000. At the office or
agency of the Company referred to on the face hereof, and in the manner and
subject to the limitations provided in the Indenture, without payment of any
service charge but with payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in connection with any registration or
substitution of Debentures, Debentures may be substituted for a like aggregate
principal amount of Debentures of other authorized denominations.

     The Debentures will not be redeemable at the option of the Company prior to
February 16, 1999.  On or after such date and prior to maturity the Debentures
may be redeemed at the option of the Company as a whole, or from time to time in
part, upon mailing a notice of such redemption not less than 30 nor more than 60
days before the date fixed for redemption to the holders of Debentures at their
last registered addresses, all as provided in the Indenture, at the following
redemption prices (expressed as percentages of the principal amount),
together in each case with accrued interest to the date fixed for redemption.

time on or after that date, the Debentures are redeemable at the following

        Subject to the provisions of the Indenture, the holder hereof has the

redemption (unless the Company shall default in payment due upon redemption
thereof), to exchange the principal hereof or any portion of such principal
which is $1,000 or an integral multiple thereof, into Exchange Property, as said
Exchange Property shall be constituted at the date of exchange, obtained by
dividing the principal amount of this Debenture or portion thereof to be
exchanged by the Exchange Price, which shall initially be equivalent to an
exchange rate of ________ shares of Armor All Common Stock for each $1,000
principal amount of Debentures, or such Exchange Price as adjusted from time to
time as provided in the Indenture, upon surrender of this Debenture, together
with an exchange notice as provided in the Indenture, to the Company at the
office or agency of the Company maintained for that purpose in the Borough of
Manhattan, the City of New York, or at the option of such holder, the Corporate
Trust Office of the Trustee, and, unless any securities included in the Exchange
Property issuable on exchange are to be issued in the same name as this
Debenture, duly endorsed by, or accompanied by instruments of transfer in form
satisfactory to the Company duly executed by, the holder or by his duly
authorized attorney.  No adjustment in respect of interest or dividends will be
made upon any exchange; provided, however, that if this Debenture shall be
                        ----------------- 
surrendered for exchange during the period from the close of business on any
record date for the payment of interest through the close of business on the
Business Day next preceding the following interest payment date, this Debenture
(unless it or the portion being exchanged shall have been called for redemption
on a date in such period) must be accompanied by an amount, in funds acceptable
to the Company, equal to the interest payable on such interest payment date on
the principal amount being exchanged.  No fractional shares or interests will be
issued upon any exchange, but an adjustment in cash will be made, as provided in
the Indenture, in respect of any fractional share or interest which would
otherwise be issuable upon the surrender of any Debenture or Debentures for
exchange.

        Any Debentures called for redemption, unless surrendered for exchange on
or before the close of business on the date fixed for redemption, may be deemed
to be purchased from the holder of such Debentures at an amount equal to the
applicable redemption price, together with accrued interest to the date fixed
for redemption, by one or more investment bankers or other purchasers who may
agree with the Company to purchase such Debentures from the holders thereof and
exchange them into Exchange Property and to make payment for such Debentures as
aforesaid to the Trustee in trust for such holders.

        Upon due presentment for registration of transfer of this Debenture at
the Corporate Trust Office of the Trustee, a new Debenture or Debentures of
authorized denominations for an equal aggregate principal amount will be issued
to the transferee in substitution thereof, subject to the limitations provided
in the

Indenture, without charge except for any tax or other governmental charge
imposed in connection therewith.

        The Company, the Trustee, the Exchange Agent, any authenticating agent,
any paying agent and any Debenture registrar may deem and treat the registered
holder hereof as the absolute owner of this Debenture (whether or not this
Debenture shall be overdue and notwithstanding any notation of ownership or
other writing hereon made by anyone other than the Company or any Debenture
registrar), for the purpose of receiving payment hereof, or on account hereof,
for the exchange hereof and for all other purposes, and neither the Company nor
the Trustee nor any other authenticating agent nor any paying agent nor the
Exchange Agent nor any Debenture registrar shall be affected by any notice to
the contrary.  All payments made to or upon the order of such registered holder
shall, to the extent of the sum or sums paid, satisfy and discharge liability
for monies payable on this Debenture.

        No recourse for the payment of the principal of or any premium or
interest on this Debenture, or for any claim based hereon or otherwise in
respect hereto, and no recourse under or upon any obligation, covenant or
agreement of the Company in the Indenture or any indenture supplemental thereto
or in any Debenture, or because of the creation of any indebtedness represented
thereby, shall be had against any incorporator, stockholder, officer or
director, as such, past, present or future, of the Company or of any successor
corporation, either directly or through the Company or any successor
corporation, whether by virtue of any constitution, statute or rule of law or by
the enforcement of any assessment or penalty or otherwise, all such liability
being, by the acceptance hereof and as part of the consideration for the issue
hereof, expressly waived and released.

                    Terms used in this Debenture and defined in the Indenture
are used herein as therein defined.

     Re:  McKesson Corporation and Armor All Products 
          Corporation -- Registration Statement on Form S-3


Ladies and Gentlemen:

     We are acting as counsel for McKesson Corporation, a Delaware corporation
("McKesson"), and Armor All Products Corporation, a Delaware corporation 
("Armor All"), in connection with the registration under the Securities Act of
1933, as amended, of $200,000,000 aggregate principal amount of McKesson's 
___% Exchangeable Subordinated Debentures Due 2004 (the "Debentures"), 
including $20,000,000 aggregate principal amount of Debentures subject to the 
underwriters' over-allotment option, and an indeterminable number of shares of
Armor All's Common Stock, par value $.01 per share (the "Armor All Common 
Stock"), deliverable by McKesson upon exchange of the Debentures pursuant to 
the Indenture dated as of March __, 1994 between McKesson and The First 
National Bank of Chicago, as Trustee (the "Indenture").  In this regard, we 
have participated in the preparation of a Registration Statement on Form S-3 
(Registration No. 33-52075) relating to the Debentures and to such shares of 
Armor All Common Stock (the "Registration Statement").

     We advise you that in our opinion:

     1.  McKesson is a corporation duly organized, validly existing and in 
good standing under the laws of the State of Delaware.

     2.  The issuance and sale of the Debentures have been duly authorized by 
the Board of Directors of McKesson.  When the

Debentures have been issued and sold in accordance with the terms of the 
Indenture, the Debentures will be the legally binding obligations of McKesson 
entitled to the benefits of the Indenture.

     3.  The shares of Armor All Common Stock owned by McKesson and 
deliverable by McKesson upon exchange of Debentures, pursuant to the 
Indenture, have been legally issued and are fully paid and non-assessable.

     We hereby consent to the filing of this opinion as Exhibit 5.1 to the 
Registration Statement and to the use of our name under the caption "Legal 
Matters" in the Registration Statement and in the Prospectus included therein.
 

                                         Very truly yours,
