                               PROSPECTUS SUMMARY
 
  The following summary is qualified in its entirety by the more detailed
information appearing elsewhere in this Prospectus as well as the information
appearing in the documents incorporated by reference herein. Investors should
carefully consider the information set forth under the caption "Risk Factors."
 
                                  THE COMPANY
 
  The Company, through its wholly-owned operating subsidiary, Interstate Brands
Corporation ("Brands"), is the largest baker and distributor of fresh bakery
products in the United States. The Company produces, markets, distributes and
sells a wide range of breads, rolls, snack cakes, donuts, sweet goods and
related products. These products are sold under a number of national brand
names, such as "Wonder(R)," "Hostess(R)" and "Home Pride(R)," as well as
regional brand names, including "Butternut(R)," "Dolly Madison(R)" and
"Merita(R)." "Wonder(R)" white bread and "Home Pride(R)" wheat bread are the
number one and two selling branded breads sold in the United States.
"Hostess(R)" products, including "Twinkies(R)," "CupCakes" and "Ho-Hos(R)," are
among the leading snack cake products sold in the United States.
 
  The Company distributes its products in markets representing approximately
90% of the United States population. The Company operates 67 bakeries and more
than 1,400 thrift stores and employs over 32,000 people. The Company's driver-
salesmen deliver products directly from the Company's over 1,200 distribution
centers to more than 200,000 food outlets and stores.
 
  The Company has grown to its present size primarily through the acquisition
of other bakery businesses. In July 1995, the Company acquired Continental
Baking Company ("CBC") from Ralston for $220,000,000 in cash and 16,923,077
shares of the Common Stock. Since the acquisition of CBC, the Company has taken
significant steps to continue to build and capitalize on the brand equity in
the "Wonder(R)" and "Hostess(R)" brands. The Company has also worked to realize
cost savings from the CBC acquisition and to achieve economies of scale in the
operations of Brands and CBC. As a result of the CBC acquisition and these
actions, the Company has significantly increased net sales and profitability.
The Company has more than doubled its net sales to $2.9 billion in fiscal 1996
from $1.2 billion in fiscal 1995. The Company's operating income as a
percentage of net sales increased to 5.5% for the forty weeks ended March 8,
1997 from 2.6% for the comparable period in fiscal 1996. Net income per share
increased to $1.78 per share for the forty week period in fiscal 1997 from $.47
per share for the comparable period in fiscal 1996.
 
  The principal executive offices of the Company are located at 12 East Armour
Boulevard, Kansas City, Missouri 64111, and its telephone number is (816) 502-
4000.
 
                               INDUSTRY OVERVIEW
 
  Annual bread and cake sales in the United States were approximately $23
billion in 1996 according to Datamonitor. Nutritional guidelines have helped
focus consumers on the benefits of grain-based foods. The Company believes
that, through its extensive line of bread products, it is well positioned to
take advantage of this trend.
 
  In addition to the Company, several large baking and diversified food
companies market bread and cake products under various brand names in the
United States. There are also a significant number of medium and small baking
companies that sell bread and cake products in certain regions of the United
States. The Company believes that the larger, national baking companies enjoy
significant competitive advantages over smaller operations due principally to
their economies of scale in areas such as purchasing, advertising, marketing
and distribution, as well as greater brand awareness.
 
 
                                       3
<PAGE>
 
  A significant trend in the bread and cake baking industry over the last
several years has been the consolidation of smaller bakeries into larger baking
businesses. Consolidation, which has reduced industry capacity, continues to be
driven by several factors including generational changes at family-owned
operations as well as capital constraints on smaller bakeries which limit their
ability to make major capital investments necessary to increase productivity
and develop new products. The Company believes the baking industry will
continue to present opportunities for strategic acquisitions that will
complement its existing business.
 
                               BUSINESS STRATEGY
 
  The Company's strategy is to increase shareholder value by focusing on the
following elements:
 
DEVELOP AND SUPPORT BRANDED PRODUCTS
 
  The Company continues to emphasize higher-margin branded products in order to
increase net sales and profitability. The Company's experience has shown that
branded products generally have a higher consumer awareness, resulting in
premium pricing and increased shelf space. The Company supports its brands
through aggressive marketing and advertising campaigns specifically tailored to
selected target markets and consumer categories. In addition, since the CBC
acquisition, the Company has implemented a new advertising campaign for its
leading national brands. The Company believes its focus on freshness and high
quality products will continue to enhance its brand-building efforts.
 
  The Company operates a research and development facility in Kansas City,
Missouri, which engages in new product development, line extensions of existing
products and the enhancement of product graphics and packaging. For example,
the Company recently introduced fat free bread products under the "Wonder(R)"
and "Butternut(R)" brand names in certain test markets, as well as new
"Hostess(R)" packaging to enhance shelf appeal of its snack cake products.
 
MAINTAIN DECENTRALIZED OPERATIONS
 
  The Company's decentralized operations and related incentive programs are key
elements of the Company's business strategy to increase net sales and improve
profitability. The Company is organized into bakery profit centers, each
operating as a stand-alone business responsible for sales, pricing,
manufacturing, distribution, accounting and data processing. The Company
compensates local bakery management under an incentive bonus program tied to
operating cash flow targets for each profit center. The corporate staff
provides direction and focus to the plants in areas such as quality and brand
building, while also providing centralized support in national advertising and
promotion, purchasing, legal and human resources.
 
  The Company believes its presence throughout the United States helps it to
compete successfully with regionally-based competition as well as minimize
exposure to regional economic downturns. The Company's plants and distribution
depots across the United States position the Company close to major
marketplaces enabling the Company to provide efficient delivery and superior
customer service.
 
PURSUE STRATEGIC ACQUISITIONS
 
  The Company believes that the size and geographic scope of its operations
position it for growth through selective acquisitions in the consolidating
baking industry. The Company pursues acquisition candidates that complement its
existing product lines and geographic presence and leverage its purchasing
power, brand management capabilities and operating efficiencies. For example,
in March 1997, the Company acquired the assets comprising the San Francisco
French Bread Company ("SFFB"), a producer and distributor of sourdough breads,
from Metz Baking Company. In addition, in April 1997, the Company acquired the
right to use the trademark "Marie Callender's(R)" in connection with the
manufacture, marketing, distribution and sale of croutons.

                             COMMON STOCK PURCHASE
 
  In connection with the SAILS transaction, the Company and Ralston have
entered into an agreement pursuant to which the Company has agreed to
repurchase, simultaneously with the closing of the SAILS transaction, 1,000,000
shares of its Common Stock from Ralston at a purchase price per share equal to
the Initial Price (as that term is defined in the SAILS Prospectus) less a 3%
discount (the "Repurchase Transaction"). See "Selling Stockholder."
 
                                  THE OFFERING
 
  Pursuant to the terms of the SAILS, Ralston may deliver          shares of
Common Stock to the holders of the SAILS at the maturity thereof. This
Prospectus relates to the delivery by Ralston of such shares of Common Stock,
and up to           additional shares of Common Stock with respect to the SAILS
that are subject to an over-allotment option granted by Ralston to the
Underwriters in the SAILS offering solely to cover over-allotments. The SAILS
are being offered by Ralston pursuant to the SAILS Prospectus. To the extent
the over-allotment option is not exercised by the Underwriters in full, Ralston
may, at its option, but not sooner than 90 days from the date of this
Prospectus, sell the unexercised portion of up to           shares of Common
Stock pursuant to this Prospectus. Ralston owns 16,923,077 shares of Common
Stock, constituting approximately 45% of the Company's outstanding Common
Stock, as of March 8, 1997.

                           FORWARD-LOOKING STATEMENTS
 
  Certain statements incorporated by reference or made in this Prospectus under
the captions "Prospectus Summary," "Risk Factors," "Business" and "Management's
Discussion and Analysis of Financial Condition and Results of Operations," and
elsewhere in this Prospectus are "forward-looking statements" within the
meaning of the Private Securities Litigation Reform Act of 1995, and are
subject to the safe harbor created by that Act. Such forward-looking statements
include, without limitation, the future availability and prices of raw
materials, the availability of capital on acceptable terms, the competitiveness
of the bread and cake industry, potential environmental liabilities and the
Company's strategies and other statements contained herein that are not
historical facts. Because such forward-looking statements involve risks and
uncertainties, there are important factors that could cause actual results to
differ materially from those expressed or implied by such forward-looking
statements. Factors that could cause actual results to differ materially
include, but are not limited to, changes in general economic and business
conditions (including in the bread and cake markets), the Company's ability to
recover its raw material costs in the pricing of its products, the availability
of capital on acceptable terms, actions of competitors, the extent to which the
Company is able to develop new products and markets for its products, the time
required for such development, the level of demand for such products, changes
in the Company's business strategies and other factors discussed under "Risk
Factors."
 
                                  RISK FACTORS
 
PRICES AND AVAILABILITY OF RAW MATERIALS
 
  The principal raw materials used in the baking business are flour, sugar and
edible oils, all of which are subject to substantial price fluctuations. Any
substantial increase in the prices of raw materials would, if not offset by
product price increases, have an adverse impact on the profitability of the
Company. Historically, the Company has been able to recover the majority of its
commodity cost increases through increasing prices, switching to a higher-
margin revenue mix and obtaining additional operating efficiencies. There can
be no assurance, however, that the Company will continue to be able to offset
raw material price increases to the same extent in the future. From time to
time the Company enters into contracts, generally not longer than one year in
duration, for the purchase of baking ingredients at fixed prices which are
designed to protect the Company against raw material price increases during
their term. These contracts could result in the Company paying higher prices
for its raw materials than would otherwise be available in the spot markets.
The bakery operations of the Company are also dependent upon natural gas and
propane as a fuel for firing ovens, and the Company's distribution operation is
dependent upon the price and availability of motor fuel, particularly gasoline
and diesel fuel. Substantial future increases in prices or shortages of such
fuels could have a material adverse effect on the Company.
 
HIGHLY COMPETITIVE BAKING INDUSTRY
 
  The baking industry is highly competitive. The Company faces competition in
all of its markets from large, national bakeries and smaller, regional
operators, as well as from supermarket chains with their own bakeries or
private label products and grocery stores with their own in-store bakeries.
Some of the Company's competitors, including other diversified food companies,
are larger and have greater financial resources than the Company. The Company
from time to time experiences price pressure in certain of its markets as a
result of competitors' promotional pricing practices. Competition is based on
product quality, price, brand loyalty, effective promotional activities and the
ability to identify and satisfy emerging consumer preferences. Customer
service, including frequency of deliveries and maintenance of fully stocked
shelves, is also an important competitive factor and is central to the
competition for retail shelf space among bread and cake product distributors.
See "Business--Competition."
 
 
                                       7
<PAGE>
 
AVAILABILITY AND INTEGRATION OF FUTURE ACQUISITIONS
 
  Historically, the Company's growth has depended, in large part, on its
ability to acquire and, thereafter, integrate and operate additional baking
businesses. The Company's strategy includes pursuing acquisition candidates
that complement its existing product lines and geographic presence and
leverage its purchasing power, brand management capabilities and operating
efficiencies. The Company presently has no acquisitions under consideration.
Potential competitors for acquisition opportunities include larger companies
with significantly greater financial resources. Competition for the
acquisition of baking businesses may result in acquisitions on terms that
prove to be less advantageous to the Company than have been attainable in the
past or may increase acquisition prices to levels beyond the Company's
financial capability. The Company's financial capability to make acquisitions
is partially a function of its ability to access the debt and equity capital
markets. In addition, there can be no assurance that the Company will find
attractive acquisition candidates in the future or succeed in reducing the
costs and increasing the profitability of any business acquired in the future.
 
ANTI-TAKEOVER PROVISIONS
 
  Certain provisions of the Company's Certificate of Incorporation and Bylaws
and Delaware law could discourage potential acquisition proposals and could
delay or prevent a change in control of the Company. The Company is authorized
to issue up to one million shares of Preferred Stock, the relative rights and
preferences of which may be fixed by the Company's Board of Directors, without
stockholder approval. While the Company has no present plans to issue any
shares of Preferred Stock, the future issuance thereof could have the effect
of making it more difficult for a third party to acquire, or of discouraging a
third party from acquiring, outstanding voting stock of the Company. The
Company's Certificate of Incorporation requires that any business combination
(as defined) with a stockholder who beneficially owns more than 5% or more of
the Company's outstanding voting stock be approved, subject to certain
exceptions, by a majority of stockholders not involved in the transaction. In
addition, provisions of Delaware law prohibit the Company from engaging in a
business combination (as defined) with a person who, together with affiliates
and associates own (or within three years prior to the proposed business
combination, did own) 15% or more of the Company's voting stock. The Company's
Certificate of Incorporation provides for a classified board of directors with
staggered three-year terms, a provision that increases the difficulty of
removing all of the incumbent directors at one time which, in turn, could
discourage a proxy contest. Other provisions of the Company's Certificate of
Incorporation, including removal of directors only for cause and a prohibition
on action by stockholders by consent, could have similar effects. See
"Description of Capital Stock."
 
DEPENDENCE ON KEY PERSONNEL
 
  The operation of the Company requires managerial and operational expertise.
The Company does not have employment contracts with any members of current
management other than a contract with Charles A. Sullivan, Chairman of the
Board and Chief Executive Officer, which is automatically renewed on May 31 of
each year unless terminated by the Company and Brands or Mr. Sullivan. The
Company has no reason to believe that any of its key management personnel will
not continue to be active in the Company's operations.
 
RALSTON REPRESENTATIVES ON THE BOARD OF DIRECTORS
 
  Mr. William P. Stiritz and Mr. James R. Elsesser, directors of the Company,
are also Chairman of the Board and Chief Executive Officer and Chief Financial
Officer, respectively, of Ralston and owe certain fiduciary duties to Ralston
and its stockholders which may, under certain circumstances, conflict with
their fiduciary duties to the Company and its stockholders when serving as
directors of the Company. There can be no assurance that a situation involving
conflicting interests of Ralston and the Company will not arise. If the
Company's Board of Directors is presented with a proposal putting these
directors in a conflicting situation between the interests of the Company and
the interests of Ralston, they may abstain from participating in the
consideration of such proposal and any such proposal would then be considered
by, and be subject to the approval of, a majority of the disinterested
directors of the Company.
 
 
                                       8
<PAGE>
 
SHARES ELIGIBLE FOR FUTURE SALE
 
  Under the Shareholder Agreement, Ralston agreed not to own more than 14.9%
of the Company's voting securities as of July 22, 2000 and is entitled to
certain registration rights with respect to shares of Common Stock held by it.
Assuming that the Repurchase Transaction is consummated, Ralston delivers one
share of Common Stock per SAILS at their maturity and the number of
outstanding shares of Common Stock at July 22, 2000 is the same as the number
of such outstanding shares at March 8, 1997, under the Shareholder Agreement,
Ralston would be required to dispose of an additional           shares of
Common Stock prior to July 22, 2000 (          shares if the Underwriters'
overallotment option is exercised in full). Further, Ralston may determine to
sell the remainder of its shares of Common Stock at any time prior to or after
July 22, 2000. No prediction can be made as to the effect, if any, that future
sales of shares, or the availability of shares for future sale, will have on
the market price of the Common Stock prevailing from time to time. Sales of
substantial amounts of Common Stock, or the perception that such sales could
occur, could adversely affect prevailing market prices for the Common Stock.
 
IMPACT OF THE SAILS ON THE MARKET FOR THE COMMON STOCK
 
  It is not possible to predict accurately how or whether the SAILS will trade
in the secondary market. Any market that develops for the SAILS is likely to
influence and be influenced by the market for the Common Stock. For example,
the price of the shares of Common Stock could become more volatile and could
be depressed by investors' anticipation of the potential distribution into the
market of shares of Common Stock which may be delivered by Ralston upon
maturity of the SAILS. As of March 8, 1997, such shares would constitute    %
of the outstanding Common Stock (  % if the Underwriters' over-allotment
option is exercised in full). See "Selling Stockholder." The price of shares
of Common Stock could also be affected by possible sales of shares of Common
Stock by investors who view the SAILS as a more attractive means of equity
participation in the Company and by hedging or arbitrage trading activity that
may develop involving the SAILS and the Common Stock.
 
                              SELLING STOCKHOLDER
 
  Pursuant to the terms of the SAILS, Ralston may deliver           shares of
Common Stock to the holders of the SAILS at the maturity thereof. This
Prospectus relates to the delivery by Ralston of such shares of Common Stock,
and up to           additional shares of Common Stock with respect to the
SAILS that are subject to an over-allotment option granted by Ralston to the
Underwriters in the SAILS Offering solely to cover over-allotments. The SAILS
are being offered by Ralston pursuant to the SAILS Prospectus. To the extent
the over-allotment option is not exercised by the Underwriters in full,
Ralston may, at its option and not sooner than 90 days from the date of this
Prospectus, sell the unexercised portion of up to            shares of Common
Stock pursuant to this Prospectus. Ralston owns 16,923,077 shares of Common
Stock, constituting approximately 45% of the Company's outstanding Common
Stock, as of March 8, 1997.
 
  Ralston acquired its shares of Common Stock subject to the terms of a
Shareholder Agreement dated July 22, 1995 (the "Shareholder Agreement")
entered into by the Company, Ralston and a subsidiary of Ralston in connection
with the acquisition of CBC. The Shareholder Agreement provides, among other
things, that, prior to July 22, 2001, Ralston, without the consent of the
Company, shall not acquire any additional shares of Common Stock or take other
specified actions with respect to the Company, commonly the subject of
standstill agreements between an issuer and a significant stockholder. Ralston
has further agreed that by July 22, 2000, its ownership of Common Stock will
be reduced to no more than 14.9% of the Company's outstanding voting
securities. Under the Shareholder Agreement, Ralston has registration rights
with respect to the shares of Common Stock owned by it, which, however, are
subject to certain transfer restrictions. Subject to certain limited
exceptions, Ralston may not sell the Common Stock owned by it without first
offering it to the Company. The Company has waived such right of first refusal
with respect to the Common Stock which may be offered pursuant to this
Prospectus. The Company also has the right between July 22, 2000 and July 22,
2001 to acquire any Common Stock owned by Ralston, at a price equal to 110% of
its then current market price (as defined in the Shareholder Agreement).
 
                                       9
<PAGE>
 
  The Shareholder Agreement requires that Ralston vote the shares of Common
Stock owned by it in accordance with the recommendation of the Company's Board
of Directors with respect to stockholder proposals and nominations to the
Company's Board of Directors and, with respect to other proposals, in
proportion to the votes of all other stockholders; provided, however, that
Ralston may vote as it deems appropriate with respect to proposals for the
merger of the Company, the sale of all or substantially all of the Company's
assets or the issuance of any other class of voting stock of the Company. Mr.
Stiritz and Mr. Elsesser serve on the Board of Directors of the Company. Mr.
Stiritz's term expires in 1997 and Mr. Elsesser's term expires in 1999.
 
  The Company has agreed, simultaneously with the closing of the SAILS
transaction, to purchase from Ralston 1,000,000 shares of Common Stock at a
purchase price per share equal to the Initial Price (as defined in the SAILS
Prospectus) less a 3% discount.
 
  Assuming the Company's purchase of 1,000,000 shares of Common Stock from
Ralston in the Repurchase Transaction had been completed as of March 8, 1997,
Ralston would have owned 43.5% of the Common Stock. Assuming, additionally the
completion of such purchase, that Ralston delivers one share of Common Stock
per SAILS at the maturity thereof and the number of shares of Common Stock at
July 22, 2000 remains the same as the number of outstanding shares at March 8,
1997, under the Shareholder Agreement Ralston would be required to dispose of
an additional         shares of Common Stock prior to July 22, 2000 (
additional shares if the Underwriters' overallotment option is exercised in
full).
 
  For the forty weeks ended March 8, 1997, Ralston or its affiliates received
approximately $0.7 million in payments from the Company, primarily in
connection with certain post-CBC acquisition transition services.
 
                                USE OF PROCEEDS
 
  The Company will not receive any proceeds from the sale of the SAILS or
delivery thereunder of Common Stock or any other sales of shares of Common
Stock by Ralston to which this Prospectus relates.

(1) Through May 28, 1997
 
  On May 28, 1997, the last reported sale price of the Common Stock on the
NYSE Composite Tape was $53.50 per share. On May 28, 1997, the Common Stock
was held by 5,933 holders of record.
 
  The declaration of dividends is at the discretion of the Board of Directors
of the Company. The declaration and payment of future dividends and the amount
thereof will be dependent upon the Company's results of operations, financial
condition, cash requirements for its business, future prospects and other
factors deemed relevant by the Board of Directors.
 
  The ability of the Company to pay dividends on the Common Stock depends on
the ability of Brands, the Company's principal operating subsidiary, to pay
dividends to the Company. Brands has entered into a Credit Agreement (as
described in "Management's Discussion and Analysis of Financial Condition and
Results of Operations--Liquidity and Capital Resources") pursuant to which
Brands may not pay dividends or make payments in respect of the purchase of
capital stock of the Company to the extent that the aggregate amount of all
such payments made after June 4, 1995 exceeds the sum of $20 million plus 75%
of consolidated net income (as defined) for the period beginning June 4, 1995
and ending on the last day of the most recent fiscal quarter. As of March 8,
1997, Brands had $53.3 million available for such purposes. The Company
believes that it will be permitted, pursuant to a waiver to be granted by its
lenders, to perform its obligations under the Repurchase Transaction without a
reduction in the amount available under the Credit Agreement for dividends and
other stock repurchases.

  The following information contains forward-looking statements which involve
certain risks and uncertainties. See "Forward-Looking Statements."
 
THE COMPANY
 
  The Company, through Brands, is the largest baker and distributor of fresh
bakery products in the United States. The Company produces, markets,
distributes and sells a wide range of breads, rolls, snack cakes, donuts,
sweet goods and related products. These products are sold under a number of
national brand names, such as "Wonder(R)," "Hostess(R)" and "Home Pride(R),"
as well as regional brand names, including "Butternut(R)," "Dolly Madison(R)"
and "Merita(R)". "Wonder(R)" white bread and "Home Pride(R)" wheat bread are
the number one and two selling branded breads sold in the United States.
"Hostess(R)" products, including "Twinkies(R)," "CupCakes" and "Ho-Hos(R),"
are among the leading snack cake products sold in the United States.
 
  The Company distributes its products in markets representing approximately
90% of the United States population. The Company operates 67 bakeries and more
than 1,400 thrift stores and employs over 32,000 people. Its driver-salesmen
deliver products directly from the Company's over 1,200 distribution centers
to more than 200,000 food outlets and stores.
 
  The Company or its predecessors have baked and distributed fresh bread and
cake products since 1927. The Company has grown to its present size primarily
through acquisitions of other baking businesses. In its 1988 fiscal year, the
Company underwent a change in control through a leveraged buyout transaction
and acquired 10 bakeries in the Southeastern United States. In July 1991, the
Company returned to the public market by issuing shares of Common Stock. In
July 1995, the Company acquired CBC from Ralston for $220,000,000 in cash and
16,923,077 shares of the Common Stock. Since the acquisition of CBC, the
Company has taken significant steps to continue to build and capitalize on the
brand equity in the "Wonder(R)" and "Hostess(R)" brands. The Company has also
worked to realize cost savings from the CBC acquisition and to achieve
economies of scale in the operations of Brands and CBC.
 
INDUSTRY OVERVIEW
 
  Annual bread and cake sales in the United States were approximately $23
billion in 1996 according to Datamonitor. Nutritional guidelines, such as the
Food Guide Pyramid issued by the United States Department of Agriculture, have
helped focus consumers on the benefits of grain-based foods. The Company
believes that, through its extensive line of bread products, it is well
positioned to take advantage of this trend.
 
  In addition to the Company, several large baking and diversified food
companies market bread and cake products under various brand names in the
United States. There are also a significant number of medium and small baking
companies that sell bread and cake products in certain regions of the United
States. The Company believes that the larger, national baking companies enjoy
significant competitive advantages over smaller operations due principally to
their economies of scale in areas such as purchasing, advertising, marketing
and distribution, as well as greater brand awareness.
 
  A significant trend in the bread and cake baking industry over the last
several years has been the consolidation of smaller bakeries into larger
baking businesses. Consolidation, which has reduced industry capacity,
continues to be driven by several factors, including generational changes at
family-owned operations as well as capital constraints on smaller bakeries
which limit their ability to make major capital investments necessary to
increase productivity and develop new products. The Company believes that
trends in the baking industry will continue to present opportunities for
strategic acquisitions that complement its existing business.
 
  Other changes in the baking business have resulted from large conglomerates
divesting their non-core baking businesses. For example, Ralston sold CBC to
the Company in July 1995 and, in March 1996, Anheuser
 
                                      13
<PAGE>
 
Busch Company spun-off its large baking subsidiary (which became The
Earthgrains Company) to its shareholders. These divestitures have resulted in
greater management accountability to public shareholders and a larger group of
companies whose primary business is baking.
 
BUSINESS STRATEGY
 
  The Company's business strategy is to increase shareholder value by
developing and supporting branded products, maintaining decentralized
operations and pursuing strategic acquisitions.
 
 DEVELOP AND SUPPORT BRANDED PRODUCTS
 
  The Company continues to emphasize higher-margin branded products in order
to increase net sales and profitability. The Company's experience has shown
that branded products generally have a higher consumer awareness, resulting in
premium pricing and increased shelf space. The Company supports its brands
through aggressive marketing and advertising campaigns specifically tailored
to selected target markets and consumer categories. In addition, since the CBC
acquisition, the Company has implemented a new advertising campaign for its
leading national brands. The Company believes its focus on freshness and high
quality products will continue to enhance its brand-building efforts.
 
  The Company operates a research and development facility in Kansas City,
Missouri, which engages in new product development, line extensions of
existing products and enhancement of product graphics and packaging. For
example, the Company recently introduced fat free bread products under the
"Wonder(R)" and "Butternut(R)" brand names in certain test markets, as well as
new "Hostess(R)" packaging to enhance shelf appeal of its snack cake products.
 
 MAINTAIN DECENTRALIZED OPERATIONS
 
  The Company's operations are decentralized in order to increase the net
sales and profitability of its baking plants and increase efficiencies in its
distribution systems. The Company is organized into bakery profit centers,
each operating as a stand-alone business responsible for sales, pricing,
manufacturing, distribution, accounting and data processing. The Company
compensates local bakery management under an incentive bonus program tied to
operating cash flow targets for each profit center. The corporate staff
provides direction and focus to the plants in areas such as quality and brand
building, while also providing centralized support in national advertising and
promotion, purchasing, legal and human resources.
 
  The Company's believes its broad presence throughout the United States helps
it to compete successfully with regionally-based competition as well as
minimize exposure to regional economic downturns. The Company's plants and
distribution centers across the United States position the Company close to
major marketplaces enabling the Company to provide efficient delivery and
superior customer service.
 
 PURSUE STRATEGIC ACQUISITIONS
 
  The Company believes that the size and geographic scope of its operations
position it for growth through selective acquisitions in the consolidating
baking industry. The Company pursues acquisition candidates that complement
its existing product lines and geographic presence and leverage its purchasing
power, brand management capabilities and operating efficiencies. For example,
in March 1997, the Company acquired the assets of SFFB, a producer and
distributor of sourdough breads, from Metz Baking Company. In addition, in
April 1997, the Company acquired the right to use the trademark "Marie
Callender's(R)" in connection with the manufacture, marketing, distribution
and sale of croutons.
 
PRODUCTS AND BRANDS
 
  The Company produces, markets, distributes and sells white breads, variety
breads, crusty breads, reduced calorie breads, English muffins, rolls and buns
under a number of well-known national brand names, including
 
                                      14
<PAGE>
 
"Wonder(R)," "Home Pride(R)" and "Bread du Jour(R)," and regional brand names
including "Beefsteak(R)," "Buttermaid(R)," "Butternut(R)," "Colombo(R),"
"Cotton's Holsum(R)," "DiCarlo(R)," "Eddy's(R)," "Emperor Norton(R),"
"Holsum(R)," "Merita(R)," "Millbrook(R)," "Parisian(R)," "Sweetheart(R),"
"Toscano(R)," and "Weber's(R)"; bagels under the brand name "Braun's(R)"; and
croutons under the brand names "Mrs. Cubbison's(R)" and "Marie
Callender's(R)." The Company's snack cakes, donuts, sweet rolls, snack pies,
breakfast pastries, variety cakes, large cakes and shortcakes are also sold
under a number of well-known national and regional brand names, including
"Hostess(R)" and "Dolly Madison(R)." The Company is also a baker and
distributor of "Roman Meal(R)" breads, including traditional Roman Meal bread,
Roman Meal variety breads, Roman Meal light breads, Roman Meal buns, rolls and
English muffins. The Company's various brands are positioned across a wide
spectrum of consumer categories and price points.
 
  The Company believes that its brand and product trademarks such as
"Wonder(R)," "Hostess(R)," "Home Pride(R)," "Butternut(R)" and "Dolly
Madison(R)" and product trademarks such as "Twinkies(R)," "Ho-Hos(R)" and
"Zingers(R)" are of material importance to its strategy of brand building. The
Company takes appropriate action from time to time against third parties to
prevent infringement of its trademarks and other intellectual property. The
Company also enters into confidentiality agreements from time to time with
employees and third parties as necessary to protect formulas and processes
used in producing the Company's products.
 
MARKETING AND DISTRIBUTION
 
  The majority of the Company's bread sales are through supermarkets while the
Company's cake products are sold principally through supermarkets and
convenience stores. Cake sales tend to be somewhat seasonal, with a
historically weak winter period, which the Company believes is attributable to
home baking and consumption patterns during the holiday season. Spring and
early summer months are historically stronger due to increased sales of
shortcake products during the fresh strawberry season. No single customer
accounts for more than 5% of the Company's net sales.
 
  The Company's marketing and advertising campaigns are conducted through
targeted television and radio advertising, coupons in newspapers and other
printed media.
 
  The Company distributes its products in markets representing approximately
90% of the United States population, with its strongest presence in southern
California, the Pacific Northwest, the upper Midwest, the Northeast, the
Mountain States, the Middle Atlantic States and Florida. With plants and
distribution centers across the United States, the Company is located close to
the major marketplaces enabling efficient delivery and superior customer
service.
 
  The Company's fresh bakery products are delivered from the Company's network
of 67 bakeries to its over 1,200 distribution centers. The products are then
delivered primarily to grocery and convenience stores by the Company's
delivery/salesman on its more than 10,000 Company-owned routes. Unsold
products are picked up by the Company's delivery/salesman and delivered to the
Company's more than 1,400 thrift stores for retail sale. Thrift store sales
represented approximately 12% of the net sales of the Company during the forty
week period ended March 8, 1997.
 
BAKERIES AND OTHER PROPERTIES

<PAGE>
 
  The Company attempts to realize operating synergies through consolidation of
redundant facilities. For example, in 1996 the Company closed its East
Brunswick, New Jersey and Utica, New York bakeries, sold its Tempe, Arizona
bakery and closed its Dallas bakery and exchanged certain of its assets for
the Roanoke, Virginia bakery of The Earthgrains Company. As a result of these
measures, the Company was able to consolidate production of certain products,
reduce costs and more efficiently utilize its remaining facilities.
 
  The Company also makes capital investments to update or retrofit its
facilities to produce new products on existing lines and to increase line
speeds. For example, the Company retrofitted production lines in Columbus,
Georgia to produce snack cakes being produced by CBC in the Midwest and sold
in the Southeast, thereby reducing transportation costs. The Company is
completing a $20 million expansion and modernization of its Rocky Mount, North
Carolina bakery to produce bread and buns for sale in the Southeast United
States and has announced preliminary plans to build a new baking facility in
the Midwestern United States. The Company believes that its other facilities
are well maintained and does not foresee the need to make significant capital
improvements to such existing facilities in the near future.
 
 OTHER PROPERTIES
 
  The Company's over 1,200 distribution centers and more than 1,400 thrift
stores are located throughout the Company's distribution area. Generally, each
thrift store is between 500 and 1,600 square feet in size. Most of the stores
are located at the Company's distribution centers, with the remainder located
along the Company's distribution routes. The majority of the Company's
distribution centers and thrift stores are located in leased premises.
 
RAW MATERIALS
 
  The ingredients of bread and cake products, principally flour, sugar and
edible oils, are readily available from numerous sources. The Company attempts
to lock in prices for raw materials through advance purchase contracts
generally not longer than one year in duration when prices are expected to
increase. Through its program of central purchasing of baking ingredients and
packaging materials, the Company is able to utilize its national presence to
obtain competitive prices. Historically, the Company has been able to recover
the majority of its commodity cost increases through increasing prices,
switching to a higher-margin revenue mix and obtaining additional operating
efficiencies.
 
EMPLOYEES
 
  The Company employs over 32,000 people. Approximately 81% of the Company's
employees are covered by over 600 union contracts. Most of the Company's
unionized workers are members of either the International Brotherhood of
Teamsters or the Bakery, Confectionery and Tobacco Workers International
Union. The Company believes it has good relations with its union and nonunion
employees.
 
COMPETITION
 
  The Company faces intense competition in all of its markets from large,
national bakeries and smaller regional operators, as well as from supermarket
chains with their own bakeries or private label products and grocery stores
with their own in-store bakeries. Competition is based on product quality,
price, brand loyalty, effective promotional activities and the ability to
identify and satisfy emerging consumer preferences. Customer service,
including frequency of deliveries and maintenance of fully stocked shelves, is
also an important competitive factor and is central to the competition for
retail shelf space among bread and cake product distributors. The Earthgrains
Company, CPC International, Inc. and Flowers Industries, Inc. are the
Company's largest bread competitors, each marketing bread products under
various brand names. McKee Foods Corp., Tasty Baking Co., Drake Bakeries and
Entenmann's are the largest competitors of the Company with respect to cake
sales. The Company from time to time experiences price pressure in certain of
its markets as a result of competitors' promotional pricing practices.
However, the Company believes that its geographic diversity helps to limit the
effect of regionally-based competition.

GOVERNMENT REGULATION; ENVIRONMENTAL MATTERS
 
  The Company's operations are subject to regulation by various federal, state
and local governmental entities and agencies. As a baker of goods for human
consumption, the Company's operations are subject to stringent quality and
labeling standards, including the Federal Food and Drug Act. The operations of
the Company's bakeries and its delivery fleet are subject to various federal,
state and local environmental laws and workplace regulations, including the
Occupational Safety and Health Act, the Fair Labor Standards Act, the Clean
Air Act and the Clean Water Act. The Company believes that its current legal
and environmental compliance programs adequately address such concerns and
that it is in substantial compliance with such applicable laws and
regulations.
 
  The Company has underground fuel storage tanks at various locations
throughout the United States which are subject to federal and state
regulations establishing minimum standards for such tanks and where necessary,
remediation of associated contamination. The Company is presently in the
process of testing and evaluating, and, if necessary, removing, replacing or
upgrading such tanks in order to comply with such laws. In addition, the
Company has received notices from the United States Environmental Protection
Agency, state agencies, and/or private parties seeking contribution, that it
has been identified as a "potentially responsible party" (PRP), under the
"Comprehensive Environmental Response, Compensation and Liability Act", as
amended. Because of these activities, the Company may be required to share in
the cost of cleanup with respect to three "Superfund" sites. The Company's
ultimate liability in connection with these sites may depend on many factors
including the volume and type of material contributed to the site, the number
of other PRPs and their financial viability and the remediation methods and
technology to be used. While it is difficult to quantify the potential
financial impact of actions involving environmental matters, particularly
remediation costs at waste disposal sites and future capital expenditures for
environmental control equipment, in the opinion of the Company's management,
the ultimate liability arising from such environmental matters, taking into
account established accruals for estimated liabilities, should not be material
to the overall financial position of the Company, but could be material to
results of operations or cash flows for a particular quarter or annual period.
 
LEGAL PROCEEDINGS
 
  On July 20, 1995, the Company, CBC and the Antitrust Division of the United
States Department of Justice ("DOJ") signed, and filed with the United States
District Court for the Northern District of Illinois, stipulations for Final
Judgment (the "Final Judgment") and for holding separate certain assets
following the closing of the acquisition of CBC. The Final Judgment required
the divestiture of one white pan bread label in certain counties in southern
California, eastern Wisconsin, central Illinois and the Chicago area. The
Company has divested, to the satisfaction of the DOJ, certain assets in
eastern Wisconsin, central Illinois and the Chicago area, and is actively
pursuing the divestiture required in southern California pursuant to the Final
Judgment.
 
  The Company has been named as a defendant in various other claims arising
out of its normal business operations. Based upon the facts available to date,
management believes that the Company has meritorious defenses to these actions
and that their ultimate resolution will not have a material adverse effect on
the Company's financial position.

increase of $324.8 million, or 15.2%, over net sales of $2,132.5 million for
the forty weeks ended March 9, 1996. The substantial increase in year-to-date
net sales was attributable to the acquisition of CBC on July 22, 1995, with
the forty week period in fiscal 1996 reflecting only thirty-three weeks of
CBC's operations.
 
  Gross profit for the forty weeks ended March 8, 1997 was $1,251.4 million,
or 50.9% of net sales, compared with gross profit of $1,044.9 million, or
49.0% of net sales, for the forty weeks ended March 9, 1996. These
improvements resulted from synergies realized through continuing integration
of existing and acquired operations and favorable mix changes to higher-margin
branded products. These factors, along with higher selling prices, more than
offset the effect of higher ingredient costs experienced in fiscal 1997.
 
  Selling, delivery and administrative expenses were $1,036.3 million,
representing 42.2% of net sales, for the forty week period ended March 8,
1997, compared to $914.0 million, representing 42.9% of net sales, for the
prior year forty week period. Continued emphasis on cost control, integration
synergies and higher selling prices resulted in improved selling, delivery and
administrative expenses as a percent of net sales for the combined operation
for the forty week period ended March 8, 1997.
 
  Based upon these factors, operating income for the forty week period ended
March 8, 1997 was $136.1 million, an increase of $81.2 million, or 147.8%,
from the prior year's forty week operating income of $54.9 million. Operating
income was 5.5% of net sales for the forty weeks ended March 8, 1997 compared
to 2.6% of net sales in the prior year.
 
  Interest expense for the forty weeks ended March 8, 1997 was $18.0 million,
a $4.7 million decrease from the prior year. The lower expense reflects lower
average borrowing levels and interest rates during the period.
 
  The effective tax rates of 43.1% and 51.4% in the forty week periods ended
March 8, 1997 and March 9, 1996, respectively, reflect the non-deductibility
of intangible asset amortization.
 
  Reflecting the improved operations, net income for the forty week period
ended March 8, 1997 improved to $67.5 million, or $1.78 per share, from $16.0
million, or $.47 per share, for the prior year, an earnings per share
improvement of 279%.
 
 FISCAL 1996 COMPARED WITH FISCAL 1995
 
  Net sales for the fifty-two weeks ended June 1, 1996 were $2,878.2 million,
a $1,655.4 million increase over net sales of $1,222.8 million for the fifty-
three weeks ended June 3, 1995. This substantial increase was attributable to
the acquisition of CBC on July 22, 1995, with fiscal 1996 results reflecting
forty-five weeks of CBC's operations. Excluding the impact of the acquisition
and the additional week in fiscal 1995, net sales increased approximately 5.6%
for fiscal 1996. This increase reflects higher selling prices, offset by some
volume erosion in cake units.
 
  Gross profit for fiscal 1996 was $1,425.0 million, or 49.5% of net sales,
compared to the prior year's gross profit of $591.9 million, or 48.4% of net
sales. This margin improvement resulted from efficiencies of the
 
                                      19
<PAGE>
 
acquired operations, as well as synergies realized through integration of
existing and acquired operations. Excluding the impact of acquired operations,
cost of products sold reflects substantially higher ingredient and packaging
costs, offset somewhat by higher selling prices.
 
  Selling, delivery and administrative expenses for fiscal 1996 were $1,236.6
million, representing 43.0% of net sales, while the prior year's selling,
delivery and administrative expenses were $501.0 million, or 41.0% of net
sales. This unfavorable variance was attributable to the CBC acquisition, with
the new operations having higher selling and delivery labor and labor related
costs as a percentage of net sales. Selling, delivery and administrative
expenses as a percentage of net sales were consistent with the prior year,
excluding the impact of the acquisition.
 
  Depreciation and amortization for fiscal 1996 was $100.1 million, up from
$33.6 million during fiscal 1995. Property and equipment, as well as
intangibles, obtained in the acquisition of CBC were responsible for this
increased expense.
 
  Based upon these factors, operating income for fiscal 1996 was $78.8
million, an increase of $21.5 million, or 37.5%, from fiscal 1995's operating
income of $57.3 million. Operating income was 2.7% of net sales in fiscal 1996
compared to 4.7% of net sales in the prior year. Included in fiscal 1996
operating income were other charges of $9.5 million ($5.7 million and $.16 per
share on an after-tax basis) resulting from a payment due a union-administered
multi-employer pension plan which failed.
 
  Interest expense was $29.3 million for fiscal 1996, up $11.6 million, or
65.2%, from the prior year's expense of $17.7 million, with the increase
attributable to higher borrowings to finance the acquisition of CBC.
 
  The fiscal 1996 effective tax rate of 51.4%, as well as the fiscal 1995 rate
of 47.8%, reflects the nondeductibility of amortization of various
intangibles.
 
  Net income for fiscal 1996 was $24.5 million, or $.70 per share, compared to
$20.7 million, and $1.05 per share, the prior year. The per share earnings
decline was the result of increased interest expense and the additional shares
issued in conjunction with the CBC acquisition.
 
 FISCAL 1995 COMPARED WITH FISCAL 1994
 
  Net sales for the fifty-three weeks ended June 3, 1995 were $1,222.8
million, an increase of $80.1 million, or 7.0%, over net sales of $1,142.7
million for the fifty-two weeks ended May 28, 1994. This increase primarily
reflects the impact of acquisitions, unit volume gains for bread and the
additional week included in fiscal 1995.
 
  Gross profit for fiscal 1995 was $591.9 million, or 48.4% of net sales,
compared to the prior year's gross profit of $561.5 million, or 49.1% of net
sales, a $30.4 million increase but representing a lower percentage of net
sales. This margin decline was primarily attributable to higher labor and
overhead costs associated with acquisitions, as well as slightly higher
commodity costs for certain key ingredients.
 
  Selling, delivery and administrative expenses for fiscal 1995 were $501.0
million, or 41.0% of net sales, compared with $473.6 million, or 41.4% of net
sales, in fiscal 1994. This favorable variance on a percentage of net sales
basis resulted from labor and labor related efficiencies gained during fiscal
1995. Fiscal 1994 also included higher delivery costs associated with a two-
month transport drivers strike at one bakery.
 
  Depreciation and amortization increased $2.0 million in fiscal 1995 related
to the completion of the Jacksonville, Florida bakery and acquisitions.
 
  Based upon these factors, operating income for fiscal 1995 was $57.3
million, an increase of $10.4 million, or 22.2%, from fiscal 1994's operating
income of $46.9 million. Fiscal 1994 reflects $9.4 million ($5.7 million after
tax, or $.28 per share) of other charges, which includes costs related to a
plant disposal of $6.7 million and
 
                                      20
<PAGE>
 
environmental matters of $2.7 million. Operating income was 4.7% of net sales
in fiscal 1995 compared to 4.1% of net sales in fiscal 1994.
 
  Interest expense was $17.7 million in fiscal 1995, up $3.0 million, or
20.3%, over the prior year's expense of $14.7 million. This increase was
principally attributable to higher interest rates during fiscal 1995, as well
as higher debt levels resulting from an acquisition in the first quarter of
fiscal 1995.
 
  The fiscal 1995 effective tax rate of 47.8% primarily reflects the
nondeductibility of intangibles amortization. The Company's effective tax rate
of 51.2% for fiscal 1994 reflects the passage of the Omnibus Budget
Reconciliation Act of 1993 during the first fiscal quarter. The increase in
the corporate tax rate provided for in the Act raised the fiscal 1994
provision for income taxes by approximately $.8 million, or $.04 per share,
due to the cumulative adjustment of the Company's net deferred tax liability
at May 29, 1993 and the additional current taxes attributable to the fiscal
year ended May 29, 1993. Nondeductible intangibles amortization also
contributed to the higher effective rate in fiscal 1994.
 
  Net income for fiscal 1995 was $20.7 million, or $1.05 per share, up $4.9
million, or 31.4%, from fiscal 1994's $15.8 million, or $.78 per share.
 
LIQUIDITY AND CAPITAL RESOURCES
 
  Cash generated by operating activities for the forty weeks ended March 8,
1997 was $144.3 million compared to $113.6 million for the forty weeks ended
March 9, 1996. This increase reflects the acquisition of CBC and improved
operations, offset by a net increase in working capital and some reduction in
long-term liabilities. Cash generated by operations during fiscal 1997 was
used to fund capital expenditures of $54.2 million, pay common stock dividends
of $14.8 million and reduce debt by $86.2 million.
 
  Brands is a party to a credit agreement with certain banks (the "Credit
Agreement") which provides for borrowings of up to $350.0 million under a
revolving credit facility which matures on February 25, 2002. As of March 8,
1997, the unused borrowing capacity under the Credit Agreement was $97.0
million. The Credit Agreement contains covenants which, among other matters,
limit the payment of cash dividends on capital stock and capital stock
repurchases after June 4, 1995 to a total of $20.0 million plus 75% of
consolidated net income for the period beginning June 4, 1995 and ending on
the last day of the most recent fiscal quarter. As of March 8, 1997, the
Company had $53.3 million available to pay cash dividends and repurchase
capital stock.
 
  On March 29, 1997, the Company acquired the assets of SFFB. SFFB, which
produces and distributes sourdough bread and rolls throughout northern
California and in the San Diego area, had net sales in calendar year 1996 of
approximately $95 million and employs 1,100 people at five bakery locations.
In addition, in April 1997, the Company acquired the right to use the
trademark "Marie Callender's(R)" in connection with the manufacture,
marketing, distribution and sale of croutons.
 
  For fiscal 1997, the Company anticipates spending approximately $75 million
for capital expenditures, $42 million for the acquisitions described in the
preceding paragraph and $19.9 million to pay dividends on Common Stock. For
fiscal 1998, the Company anticipates cash needs of approximately $157 million,
consisting of $52 million for the Repurchase Transaction (assuming a per share
purchase price of $51.90), $85 million of planned capital expenditures and $20
million of dividends on Common Stock. The Company believes cash flows from
operations and borrowing capacity under the Credit Agreement should be
sufficient to meet all of the Company's currently anticipated cash
requirements for fiscal 1997 and fiscal 1998.

ELECTION OF DIRECTORS
 
  The Board of Directors is divided into three classes, each consisting of
three directors. All directors hold office for a term of three years. Class I
directors hold office until the Annual Meeting of stockholders in 1997, Class
II directors hold office until the Annual Meeting of stockholders in 1998 and
Class III directors hold office until the Annual Meeting of stockholders in
1999, and, in each case, until their successors are duly elected and
qualified. Of the current members of the Company's Board of Directors, two
were nominated by Ralston pursuant to the Shareholder Agreement: Mr. Stiritz
(whose current term expires in 1997) and Mr. Elsesser. In 1996, Mr. Elsesser
was re-elected by the stockholders to serve until 1999.
 
                         DESCRIPTION OF CAPITAL STOCK
 
  The following discussion of the Company's Certificate of Incorporation,
Bylaws and Delaware law is qualified in its entirety by the actual terms of
such documents and Delaware law. Copies of the Company's Certificate of
Incorporation and Bylaws have been filed with the Commission as exhibits to
the Registration Statement.
 
GENERAL
 
  The Company has the authority to issue 60,000,000 shares of Common Stock of
$.01 par value and 1,000,000 shares of Preferred Stock of $.01 par value (the
"Preferred Stock"). The Company's Board of Directors has authority (without
action by the Company's stockholders) to issue the authorized and unissued
shares of Preferred Stock in one or more series and, within certain
limitations, to determine the voting rights
 
                                      23
<PAGE>
 
(including the right to vote as a series on particular matters), preference as
to dividends and in liquidation, conversion, redemption and other rights of
each such series. The ability of the Board of Directors to issue Preferred
Stock, while providing flexibility in connection with possible acquisitions and
other corporate purposes, could have the effect of making it more difficult for
a third party to acquire, or of discouraging a third party from acquiring, a
majority of the outstanding voting stock of the Company. There are no shares of
Preferred Stock issued or outstanding and the Company has no present plans to
issue any of the Preferred Stock.
 
COMMON STOCK
 
  Holders of Common Stock are entitled to one vote per share on all matters to
be voted on by stockholders, including the election of directors. Stockholders
are not entitled to cumulative voting rights, and accordingly, the holders of a
majority of the shares voting for the election of directors can elect the
entire Board if they choose to do so and, in that event the holders of the
remaining shares of Common Stock will not be able to elect any person to the
Board of Directors. Shares of Common Stock held by Ralston are subject to
certain voting restrictions as set forth in the Shareholder Agreement, which,
among other things, requires Ralston to vote its shares of Common Stock in
accordance with the recommendation of the Company's Board of Directors with
respect to the election of Directors. See "Selling Stockholder." Pursuant to
the Company's Bylaws, the number of directors of the Company may be not less
than five nor more than nine, as determined from time to time by the directors.
The number of directors is currently nine. The Company's Certificate of
Incorporation provides that the Board of Directors be divided into three
classes in respect of term of office, each class to contain as near as may be
one-third of the whole number of the Board. At each Annual Meeting of
stockholders, one class of directors is elected to serve until the Annual
Meeting of stockholders held three years next following and until their
successors are elected and qualified. See "Management--Election of Directors."
In the event any vacancy occurs on the Board of Directors, the Bylaws give the
remaining directors the power to fill the vacancy for the balance of the term
of office.
 
  The holders of shares of Common Stock are entitled to receive such dividends,
if any, as may be declared from time to time by the Board of Directors, in its
discretion, from funds legally available therefor and subject to the prior
dividend rights of holders of any shares of Preferred Stock which may be
outstanding. Upon liquidation or dissolution of the Company, subject to prior
liquidation rights of holders of Preferred Stock, if any, the holders of shares
of Common Stock are entitled to receive on a pro rata basis the remaining
assets of the Company available for distribution. Holders of shares of Common
Stock have no preemptive or other subscription rights, and there are no
conversion rights or redemption or sinking fund provisions with respect to such
shares.
 
APPROVAL OF BUSINESS COMBINATIONS WITH INTERESTED STOCKHOLDERS
 
  Generally, pursuant to the Company's Certificate of Incorporation, any
business combination between the Company and a stockholder who beneficially
owns 5% or more of the Company's outstanding voting stock (an "Interested
Stockholder"), which would include Ralston, must be approved by the affirmative
vote of not less than 66 2/3% of the Company's outstanding voting stock held by
the stockholders who are not involved in the transaction. Exceptions to this
rule exist for: (1) a business combination that is solely between the Company
and another corporation whose voting stock is 100% owned, directly or
indirectly, by the Company, and (2) a business combination that is a merger or
consolidation and the value of the consideration to be received per share by
holders of Common Stock is not less than the highest per-share price (with
appropriate adjustments for recapitalizations and for stock splits, stock
dividends and like distributions), paid by the Interested Stockholder in
acquiring any of its holdings of Common Stock. Further, the conditions of the
provision may be waived by the Company's Board of Directors in appropriate
circumstances as set forth in the Certificate of Incorporation.
 
  The term "business combination" generally includes: (1) a merger or
consolidation of the Company or a subsidiary with or into an Interested
Stockholder; (2) a sale, lease, exchange, transfer or other disposition to an
Interested Stockholder of all or any substantial part of the assets either of
the Company or of a subsidiary; (3) any merger or consolidation of an
Interested Stockholder with or into the Company or a subsidiary; (4) any sale,
 
                                       24
<PAGE>
 
lease, exchange, transfer or other disposition of all or any substantial part
of the assets of an Interested Stockholder to the Company or a subsidiary; (5)
except in certain circumstances, the issuance of any securities of the Company
or a subsidiary to an Interested Stockholder; (6) any recapitalization that
would have the effect of increasing the voting power of an Interested
Stockholder by more than 10%; and (7) any agreement, contract or other
arrangement providing for any of the transactions described above.
 
  In addition, the Company is subject to the provisions of Section 203 of the
Delaware General Corporation Law (the "DGCL"), an anti-takeover law. In
general, the statute prohibits a publicly held Delaware corporation from
engaging in a "business combination" with an "interested stockholder" for a
period of three years after the date of the transaction in which the person
became an interested stockholder, unless the business combination is approved
in a prescribed manner. A "business combination" includes a merger, asset sale
or other transaction resulting in a financial benefit to the stockholder. An
"interested stockholder" is a person who, together with affiliates and
associates, own (or within three years prior to the proposed business
combination, did own) 15% or more of the corporations voting stock. The
Company has not opted to elect out of Section 203 of the DGCL.
 
OTHER PROVISIONS OF THE CERTIFICATE OF INCORPORATION
 
  Any Director of the Company, or the entire Board of Directors, may be
removed from office only for "cause" (as such term is defined in the Company's
Certificate of Incorporation) and only by the affirmative vote of the holders
of a majority of the voting power of all of the shares of the Company entitled
to vote for the election of Directors, voting together as a single class. The
size of the Board of Directors may generally only be increased by majority
vote of the Directors then in office. Newly created directorships resulting
from any such increase in the authorized number of Directors and any vacancies
in the Board of Directors may be filled only by majority vote of the Directors
then in office, even though less than a quorum, or by a sole remaining
Director, and Directors so chosen shall hold office for a term expiring at the
Annual Meeting of stockholders at which the term of the class or classes to
which they have been elected expires.
 
  The Company's Certificate of Incorporation provides that special meetings of
the Company's stockholders may be called only by the Board of Directors, and
the power of the stockholders, or any of them, to call special meetings of the
stockholders is specifically denied. No action required to be taken or which
may be taken at any Annual Meeting or Special Meeting of the stockholders of
the Company may be taken without a meeting, and the power of the stockholders
to consent in writing to the taking of any action is specifically denied.
 
  The affirmative vote of at least 66 2/3% of the shares of the Company then
entitled to be voted in an election of Directors is required to amend or
repeal, or to adopt any provision inconsistent with, the provisions of the
Company's Certificate of Incorporation relating to a classified board as
described under "Common Stock" above or as described in the above two
paragraphs.

  UMB Bank, n.a., Kansas City, Missouri, is the co-transfer agent and co-
registrar with the Company for the Company's Common Stock.

  The Underwriting Agreement provides that the obligations of the Underwriters
are subject to certain conditions precedent and that the Underwriters will be
obligated to purchase all of the SAILS (other than those SAILS covered by the
overallotment option described below) if any are purchased. The Underwriting
Agreement provides that, in the event of a default by an Underwriter, in
certain circumstances the purchase commitments of non-defaulting Underwriters
may be increased or the Underwriting Agreement may be terminated.
 
  Ralston has granted to the Underwriters an option, expiring at the close of
business on the 30th day after the date of the SAILS Prospectus, to purchase
up to                  additional SAILS, at the initial public offering price
less the underwriting discounts and commissions, all as set forth on the cover
of the SAILS Prospectus. Such option may be exercised only to cover over-
allotments in the sale of the SAILS. To the extent such option is exercised,
each Underwriter will become obligated, subject to certain conditions, to
purchase approximately the same percentage of such additional SAILS as it was
obligated to purchase pursuant to the Underwriting Agreement. To the extent
such option is not exercised in full, subject to the second paragraph below,
Ralston may sell the unexercised portion of up to         shares of Common
Stock pursuant to this Prospectus.
 
  The Company has been advised by the Underwriters that they propose to offer
the SAILS to the public initially at the offering price set forth on the cover
of the SAILS Prospectus and to certain dealers at such price less a concession
of $       per SAILS, and the Underwriters and such dealers may allow a
discount of $       per SAILS on sales to other dealers. After the initial
public offering, the public offering price and concession and discount may be
changed by the Representatives.
 
  Except as otherwise described herein, the Company, its directors and
officers and Ralston and its wholly owned subsidiaries have agreed not to
issue, sell, offer, agree to sell, pledge or otherwise dispose of, directly or
indirectly, or file with the Commission a registration statement under the
Securities Act relating to any additional shares of Common Stock, any options,
warrants or other rights to purchase any Common Stock, or any securities
convertible into or exercisable or exchangeable for shares of Common Stock,
other than (i) the sale of shares of Common Stock by Ralston to the Company
and (ii) options granted and Common Stock issued pursuant to the Company's
existing employee benefit and stock option plans, without the prior written
consent of Credit Suisse First Boston Corporation, for a period of 90 days
after the date of this Prospectus.

  The SAILS will be a new issue of securities with no established trading
market. The Underwriters have advised the Company that one or more of them
intends to act as a market maker for the SAILS. However, the Underwriters are
not obligated to do so and may discontinue any market making at any time
without notice. No assurance can be given as to the liquidity of the trading
market for the SAILS.
 
  Upon the maturity of the SAILS, Ralston has the option to pay cash or
deliver shares of Common Stock pursuant to the terms of the SAILS. For a
description of the terms of such exchange, see the SAILS Prospectus.
 
  The Company and Ralston have agreed to indemnify the Underwriters against
certain liabilities, including civil liabilities under the Securities Act, or
contribute to payments which the Underwriters may be required to make in
respect thereof.
 
  In the Shareholder Agreement, the Company agreed, subject to certain
limitations, that it would indemnify Ralston against certain liabilities,
including those under the Securities Act, for any untrue statement of a
material fact or omission or alleged omission of a material fact required to
be made so as to make the statements not misleading, in connection with the
delivery of this Prospectus.
 
  The Representatives, on behalf of the Underwriters, may engage in over-
allotment, stabilizing transactions, syndicate covering transactions and
penalty bids in accordance with Regulation M under the Exchange Act. Over-
allotment involves syndicate sales in excess of the offering size, which
creates a syndicate short position. Stabilizing transactions permit bids to
purchase the underlying security so long as the stabilizing bids do not exceed
a specified maximum. Syndicate covering transactions involve purchases of the
SAILS in the open market after the distribution has been completed in order to
cover syndicate short positions. Penalty bids permit the Representatives to
reclaim a selling concession from a syndicate member when the SAILS originally
sold by such syndicate member are purchased in a syndicate covering
transaction to cover syndicate short positions. Such stabilizing transactions,
syndicate covering transactions and penalty bids may cause the price of the
SAILS to be higher than it would otherwise be in the absence of such
transactions.
 
  Certain of the Underwriters and their respective affiliates engage in
transactions with, and perform services for, the Company and Ralston in the
ordinary course of business, including various investment banking services.
 
                                 LEGAL MATTERS
 
  Certain legal matters will be passed upon for the Company by Shook, Hardy &
Bacon L.L.P., Kansas City, Missouri.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
  Section 145 of the Delaware General Corporation Law ("DGCL") provides that a
corporation may indemnify any person who was or is a party or is threatened to
be made a party to any threatened, pending or completed action or proceeding,
whether civil, criminal, administrative or investigative, other than by or in
the right of the corporation, by reason of the fact that he is or was a
director, officer, employee or agent of the corporation or is or was serving
at its request in such capacity in another corporation or business
association, against expenses (including attorneys' fees), judgments, fines
and amounts paid in settlement actually and reasonably incurred by him in
connection with such action, suit or proceeding if he acted in good faith and
in a manner he reasonably believed to be in or not opposed to the best
interests of the corporation, and, with respect to any criminal action or
proceeding, had no reasonable cause to believe his conduct was unlawful.
 
  Article Seventh of the Company's Charter provides that the Company shall, to
the fullest extent permitted by Section 145 of the DGCL, indemnify all persons
whom it may indemnify pursuant thereto and shall advance expenses of
litigation to directors and officers in accordance with the procedures and
limitations set forth in the Company's bylaws (the "Bylaws").
 
  The Bylaws generally provide that in any threatened, pending, or completed
actions, suits or proceedings, whether civil, criminal administrative or
investigative (collectively, the "Actions"), other than by or in the right of
the Company, the Company must indemnify any person who is a party or is
threatened to be made a party by reason of the fact that he or she is or was
or has agreed to become a director, officer, employee or agent of the Company,
or is or was serving or has agreed to serve at the request of the Company as a
director, officer, employee or agent of another entity, or by reason of any
action alleged to have been taken or omitted in such capacity (the
"Indemnified Party") against costs, charges and expenses (including attorneys'
fees), judgments, fines and amounts paid in settlement actually and reasonably
incurred in connection with such Actions and any appeal therefrom, if he or
she acted in good faith and in a manner he or she reasonably believed to be in
or not opposed to the best interests of the Company, and, with respect to any
criminal Action, had no reasonable cause to believe his or her conduct was
unlawful. The termination of any Action by judgment, order, settlement,
conviction, or upon a plea of nolo contendere or its equivalent, does not, of
itself, create a presumption that the person did not meet the required
standard of conduct.
 
                                     II-1
<PAGE>
 
  The Bylaws further generally provide that in an Action by or in the right of
the Company, the Company must indemnify an Indemnified Party against costs,
charges and expenses (including attorneys' fees) actually and reasonably
incurred in connection with the defense or settlement of such Action and any
appeal therefrom, if he or she acted in good faith and in a manner he or she
reasonably believed to be in or not opposed to the best interests of the
Company, except that no indemnification shall be made in respect of any claim
as to which the Indemnified Party shall have been adjudged to be liable to the
Company for gross negligence or misconduct in the performance of his or her
duty to the Company unless and only to the extent that the Court of Chancery
of Delaware or the court in which such action was brought shall determine
that, despite the adjudication of such liability but in view of all the
circumstances of the case, such person is fairly and reasonably entitled to
indemnity for such costs, charges and expenses which the court shall deem
proper.
 
  The Bylaws contain other specific provisions regarding matters such as the
avoidance by the Company of the indemnification obligations if the applicable
standards of conduct are not met, the advancement of expenses to an
Indemnified Party and the inability of the Company to amend or repeal the
Bylaws to adversely affect or deny to an Indemnified Party any rights he or
she may be entitled to under the Bylaws.
 
  Section 102(b)(7) of the DGCL permits a corporation to provide in its
certificate of incorporation that a director of the corporation shall not be
personally liable to the corporation or its stockholders for monetary damages
for breach of fiduciary duty as a director, except for liability (i) for any
breach of the director's duty of loyalty to the corporation or its
stockholders, (ii) for acts or omissions not in good faith or which involve
intentional misconduct or a knowing violation of law, (iii) under Section 174
of the DGCL, or (iv) for any transaction from which the director derived an
improper personal benefit.
 
  As permitted by Section 102(b)(7) of the DGCL, the Company's Charter
includes a provision that limits a director's personal liability to the
Company or its stockholders for monetary damages for breaches of his or her
fiduciary duty as a director. Article Eighth of the Company's Charter provides
that no director of the Company shall be personally liable to the Company or
its stockholders for monetary damages for breach of fiduciary duty to the
fullest extent permitted by the DGCL.
 
  The Company maintains insurance policies under which its directors and
officers are insured, within the limits and subject to the limitations of the
policies, against expenses in connection with the defense of actions, suits or
proceedings, and certain liabilities that might be imposed as a result of such
actions, suits or proceedings, to which they are parties by reason of being or
having been directors or officers of the Company.
 
  In the Underwriting Agreement, the Underwriters have agreed to indemnify the
Company and its officers, directors and controlling persons against certain
liabilities, including liabilities under the Securities Act of 1933, as
amended.

ITEM 17. UNDERTAKINGS.
 
  (a) The Company hereby undertakes:
 
    (1) To file, during any period in which offers or sales are being made, a
  post-effective amendment to this Registration Statement:
 
      (i) To include any prospectus required by Section 10(a)(3) of the
    Act;
 
      (ii) To reflect in the prospectus any facts or events arising after
    the effective date of this Registration Statement (or the most recent
    post-effective amendment thereof) which, individually or in the
    aggregate, represent a fundamental change in the information set forth
    herein or therein. Notwithstanding the foregoing, any increase or
    decrease in volume of securities offered (if the total dollar value of
    securities offered would not exceed that which was registered) and any
    deviation from the low or high end of the estimated maximum offering
    range may be reflected in the form of prospectus filed with the
    Commission pursuant to Rule 424(b) if, in the aggregate, the changes in
    volume and price represent no more than a 20% change in the maximum
    aggregate offering price set forth in the "Calculation of Registration
    Fee" table in the effective registration statement; and
 
      (iii) To include any material information with respect to the plan of
    distribution not previously disclosed in this Registration Statement or
    any material change to such information in this Registration Statement;
 
    Provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply
  if the information required to be included in a post-effective amendment by
  those paragraphs is contained in periodic reports filed with or
 
                                     II-3
<PAGE>
 
  furnished to the Commission by the Registrant pursuant to Section 13 or
  Section 15(d) of the Exchange Act that are incorporated by reference in
  this Registration Statement.
 
    (2) That, for the purpose of determining any liability under the Act,
  each such post-effective amendment shall be deemed to be a new registration
  statement relating to the securities offered therein, and the offering of
  such securities at that time shall be deemed to be the initial bona fide
  offering thereof.
 
    (3) To remove from registration by means of a post-effective amendment
  any of the securities being registered which remain unsold at the
  termination of the offering.
 
  (b) The Company hereby undertakes that, for purposes of determining any
liability under the Act, each filing of the Company's annual report pursuant to
Section 13(a) or Section 15(d) of the Exchange Act (and, where applicable, each
filing of an employee benefit plan's annual report pursuant to section 15(d) of
the Exchange Act) that is incorporated by reference in this Registration
Statement shall be deemed to be a new registration statement relating to the
securities offered therein, and the offering of such securities at that time
shall be deemed to be the initial bona fide offering thereof.
 
  (c) Insofar as indemnification for liabilities arising under the Act may be
permitted to directors, officers and controlling persons of the Company
pursuant to the foregoing provisions, or otherwise, the Company has been
advised that in the opinion of the Commission such indemnification is against
public policy as expressed in the Act and is, therefore, unenforceable. In the
event that a claim for indemnification against such liabilities (other than the
payment by the Company of expenses incurred or paid by a director, officer or
controlling person of the Company in the successful defense of any action, suit
or proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Company will, unless in
the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the Act and
will be governed by the final adjudication of such issue.
 
  (d) The Company hereby undertakes that:
 
    (1) For purposes of determining any liability under the Securities Act of
  1933, the information omitted from the form of prospectus filed as part of
  this registration statement in reliance upon Rule 430A and contained in a
  form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or
  (4) or 497(h) under the Securities Act shall be deemed to be part of this
  registration statement as of the time it was declared effective.
 
    (2) For the purpose of determining any liability under the Securities Act
  of 1933, each post-effective amendment that contains a form of prospectus
  shall be deemed to be a new registration statement relating to the
  securities offered therein, and the offering of such securities at that
  time shall be deemed to be the initial bona fide offering thereof.

Interstate Bakeries Corporation

Gentlemen:

     We have acted as counsel to Interstate Bakeries Corporation, a Delaware
corporation (the "Company"), in connection with the preparation of the
registration statement (the "Registration Statement") on Form S-3 under the
Securities Act of 1933, as amended (the "Act"), with respect to the registration
of the shares of common stock, par value $.01 per share (the "Shares"), that are
exchangeable at the option of Ralston Purina Company, a Missouri corporation,
upon the maturity of the Exchangeable Notes due 2000 offered by Ralston pursuant
to Ralston's registration statement on Form S-3 under the Act.

     For purposes of this opinion, we have examined and are familiar with
originals (or copies certified or otherwise identified to our satisfaction as
being true reproductions of originals) of (i) the Registration Statement; (ii)
the Company's Certificate of Incorporation, as amended; (iii) the Bylaws of the
Company, as amended; and (iv) such other documents, corporate records and
instruments as we have considered necessary or appropriate for purposes of this
opinion.

     In our examination, we have assumed the legal capacity of all natural
persons, the genuineness of all signatures, the authenticity of all documents
submitted to us as originals, the conformity to original documents of all
documents submitted to us as certified or photostatic copies and the
authenticity of the originals of such copies. As to any facts material to this
opinion which we did not independently establish or verify, we have relied upon
oral or written statements and representation of officers and other
representatives of the Company and others.

     Based on and subject to the foregoing and the qualifications and
limitations set forth below, we are of the opinion that the Shares have been
duly authorized by the Company and are legally issued, fully paid and
nonassessable.

     We express no opinion as to the laws of any jurisdiction other than the
General Corporation Law of the State of Delaware. The opinion set forth in this
letter is effective as of the date hereof. No expansion of our opinion may be
made by implication or otherwise. We express no opinions other than as herein
expressly set forth.

such proposal by the holders of each such class of IBC Securities (excluding the
IBC Equity owned by Ralston) and that with respect to broker non-votes and
abstentions, each class of IBC Equity owned by Ralston will be voted in the same
proportion as votes deemed "for," "against" or "abstain," giving the effect to
broker non-votes and abstentions as required under the laws and rules then

                        ARTICLE IV  RIGHT OF FIRST OFFER

     Section 4.1   Sales by Ralston.

          (a)  Except for Transfers permitted by Section 3.2 (a), (b) or (e),
     during the term of this Agreement, Ralston shall not sell any shares of IBC
     Equity to any Person unless it has first made an offer (the "First Offer")
     to sell such shares to IBC in accordance with this Article IV and such
     First Offer shall have been rejected or not accepted within the Applicable
     Acceptance Period (as hereinafter defined).

          (b)  The First Offer to IBC s hall be set forth in the form of a
     notice made in writing (the "Notice of Intention") to IBC setting forth (i)
     Ralston's desire to make a sale; and (ii) the number of shares of IBC
     Equity proposed to be sold (the "Offered Shares").

          (c)  Upon receipt of the Notice of Intention, IBC will have the right
     to purchase the Offered Shares at the IBC Market Price, exercisable by the
     delivery of an acceptance in the form of a notice in writing to Ralston by
     IBC (the "Notice of Exercise") at any time within twenty (20) calendar days
     from the date of receipt of the Notice of Intention (the "Applicable
     Acceptance Period"). The right of IBC to purchase IBC Equity will terminate
     if such Notice of Exercise is not delivered within Applicable Acceptance
     Period. IBC may assign its right to purchase the Offered Shares pursuant to
     a specific Notice of Intention, once received by IBC, to any Person, but
     may not otherwise assign its rights under this Article IV.

          (d)  In the event that IBC exercises its right to purchase the Offered
     Shares in accordance with Section 4.1(c) hereof, then Ralston must sell the
     Offered Shares to IBC at the IBC Market Price within twenty (20) days from
     the date of receipt of the Notice of Exercise delivered by IBC, subject to
     receipt of any required material third-party or governmental approvals,
     compliance with applicable laws and the absence of any injunction or
     similar legal order preventing such transaction.

     Section 4.2   Purchase of the Offered Shares.  In the event IBC rejects the
First Offer or fails to deliver a Notice of Exercise within the Applicable
Acceptance Period, then Ralston may (a) proceed with the Transfer pursuant to
Articles V, VI, VII and VIII hereof, if applicable, or (b) otherwise sell such
Offered Shares to transferees who agree to be bound by the terms and conditions
of this Agreement, in the case of a rejection, within ninety (90) days after the
delivery 
<PAGE>
 
of such rejection or, in the case of a failure to deliver a Notice of Exercise,
within ninety (90) days after the expiration of the Applicable Acceptance
Period, subject to the other terms and conditions of this Agreement.

     Section 4.3   Waiting Period with Respect to Subsequent Transfers.  In the
event that IBC does not deliver a Notice of Exercise within the Applicable
Acceptance Period and Ralston does not sell the Offered Shares, then Ralston may
not offer to sell any additional IBC Equity (other than the Offered Shares) for
a period of ninety (90) days from the expiration of the Applicable Acceptance
Period.


                            ARTICLE V  REGISTRATION

     Section 5.1   Demand Registration.

          (a)  During the term of this Agreement, upon Ralston's written request
     specifying the intended manner of disposition (a "Demand Notice"), IBC will
     use its best efforts to prepare and file with the SEC, as expeditiously as
     possible, a Registration Statement on an available form for which IBC then
     qualifies and which legal counsel for IBC deems appropriate and which form
     is available for the sale of IBC Equity in accordance with the intended
     method of distribution thereof to permit an offering of some or all of the
     shares of IBC Equity then held by Ralston and use its best efforts to cause
     such registration statement to become effective (a "Demand Registration");
     provided, however, that with respect to proposed dispositions of IBC Equity
     to shareholders of Ralston, Ralston and IBC will cooperate and use their
     respective reasonable best efforts to obtain a "no-action letter" from the
     SEC allowing such dispositions without registration.

          (b)  A Demand Registration will not be deemed to have occurred until
     it has become effective under the Securities Act (unless Ralston delivers a
     Demand Notice and subsequently withdraws the Demand Notice, in which case
     such a Demand Registration will be deemed to have occurred unless Ralston
     agrees to pay all reasonable out-of-pocket expenses associated with such
     registration actually incurred by IBC); provided, however, that if, after a
     Demand Registration has become effective, the offering of IBC Equity
     pursuant to such Demand Registration is prohibited by any stop-order,
     injunction or other order or requirement of the SEC or other governmental
     agency or court, such Demand Registration will be deemed not to have
     occurred (unless such prohibition on the sale of the IBC Equity is based on
     actions or omissions of Ralston, in which case such a Demand Registration
     will be deemed to have occurred unless Ralston agrees to pay all reasonable
     out-of-pocket expenses associated with such registration actually incurred
     by IBC).

          (c)  IBC will only be obligated to effect a total of five (5) Demand
     Registrations under Section 5.1 hereof and shall not be obligated under
     Section 5.1 hereof to effect more than one (1) Demand Registration in any
     twelve-month period (except that 
<PAGE>
 
     during each of the twelve-month periods commencing on the date hereof and
     on the fourth anniversary of this Agreement, Ralston shall be entitled to
     request up to two (2) Demand Registrations); provided, however, that IBC
     will not be required to register the IBC Equity pursuant to a Demand Notice
     under Section 5.1 hereof if at such time (i) the shares of IBC Equity which
     Ralston is requesting to be registered pursuant to Section 5.1 hereof
     constitute less than five percent (5%) of such class or series of the
     outstanding IBC Securities so requested to be registered or (ii) such
     Demand Notice is given within six (6) months after the effective date of
     any other registration of any IBC Securities under the Securities Act.

          (d)  If any Demand Registration involves an underwritten offering, the
     first lead underwriter, and, subject to the last sentence of this Section
     5.1(d), any other underwriter that will administer the offering will be
     selected by Ralston; provided, however, that such underwriter(s) shall be
     subject to the approval of IBC which approval shall not be unreasonably
     withheld. In the event there is one or more co-managers, the first such co-
     manager shall be selected by IBC, provided that such co-manager shall be
     subject to the approval of Ralston, which approval shall not be
     unreasonably withheld.

          (e)  If any Demand Registration involves an underwritten offering,
     then as many shares of IBC Securities that IBC elects may be included in
     such offering on the same terms and conditions as the IBC Equity; provided,
     however, that if the managing underwriter(s) advises Ralston and IBC that,
     in its judgment, the number of shares proposed to be included in such
     offering should be limited, then the total number of shares to be included
     in such offering will be determined by the managing underwriter(s) and IBC
     shall include in such offering (i) first, all the shares of IBC Equity that
     Ralston proposes to sell and (ii) second all the shares of IBC Securities
     that IBC proposes to sell. Except as otherwise provided for in this
     Agreement or the First Registration Rights Agreement (as hereinafter
     defined), no person other than Ralston shall be permitted to offer any IBC
     Securities under any Demand Registration pursuant to this Section 5.1
     without the prior written consent of Ralston.

     Section 5.2   Delay of Demand Registration.

          (a)  Notwithstanding anything to the contrary in Article V hereof, in
     the event that IBC determines in its reasonable judgment that it may be
     advisable to delay filing a Registration Statement described in Section 5.1
     hereof or, to withdraw such Registration Statement if such Registration
     Statement has already been filed, IBC may delay filing such, or withdraw
     such previously filed, Registration Statement for a period of not more than
     ninety (90) days from the date of receipt of the request for the Demand
     Registration if IBC furnishes to Ralston a certificate signed by the
     Chairman of the Board of IBC stating that IBC has reasonably determined
     that (i) such a filing would adversely affect any proposed financing or
     acquisition by IBC or (ii) such a filing would otherwise represent an undue
     hardship for IBC; provided, however, that IBC will be responsible for any
     reasonable out of pocket costs (excluding any decline in the IBC Market
     Price) which arise out of such delay and IBC will, at the request of
     Ralston, file or refile, as the case 
<PAGE>
 
     may be, such Registration Statement promptly after IBC, in its judgment,
     determines that it is no longer advisable to delay filing or to continue
     the withdrawal of such Registration Statement.

          (b)  IBC may not delay filing or refiling, as the case may be, a
     Registration Statement pursuant to Section 5.2(a) hereof, if following the
     delay IBC would be required to file audited financial statements other than
     audited financial statements included in IBC's annual report on Form 10-K,
     unless IBC agrees to provide such audited financial statements.

     Section 5.3   Incidental Registration.

          (a)  Right To Include IBC Equity.

               (i)  If IBC or any other Person at any time proposes to register
     any IBC Securities under the Securities Act (other than a registration of
     securities in connection with a merger, an acquisition, an exchange offer,
     or an Employee Benefit Plan maintained by IBC or its Affiliates or on Form
     S-4 or S-8 or any successor or similar form), whether or not for sale for
     its own account, in a manner which would permit registration of the IBC
     Equity for sale to the public under the Securities Act, it will give
     written notice to Ralston (to the extent permitted by such other Person's
     current contractual registration rights, if any) of its intention to do so
     and of Ralston's rights under this Section 5.3(a)(i), at least thirty (30)
     calendar days prior to the anticipated filing date of a Registration
     Statement relating to such registration (an "Incidental Notice"). Such
     Incidental Notice will offer Ralston the opportunity to include in such
     Registration Statement that number of shares of IBC Equity as Ralston may
     request. Upon the written request (which request will specify the number of
     shares of IBC Equity intended to be disposed of by Ralston pursuant to such
     Registration Statement) of Ralston made within ten (10) calendar days after
     the receipt of the Incidental Notice, IBC will use its best efforts to
     effect the registration under the Securities Act of all shares of IBC
     Equity which IBC has been so requested to register; provided, however, that
     (A) if such registration involves an underwritten offering, Ralston must
     sell its IBC Equity requested to be included in such registration to the
     underwriter(s) selected by IBC on the same terms and conditions as apply to
     other Persons, including IBC, and (B) if, at any time after receiving a
     reply from Ralston to an Incidental Notice, and prior to the effective date
     of the Registration Statement filed in connection with such registration,
     IBC decides for any reason not to register any shares of IBC Securities,
     IBC will notify Ralston and thereupon be relieved of its obligation to
     register any IBC Equity in connection with such registration.

               (ii) No registration, whether or not effected under Section
     5.3(a) hereof will relieve IBC of its obligations to effect Demand
     Registrations under Section 5.1 hereof.

          (b)  Priority in Incidental Registrations.  If a registration pursuant
     to Section 5.3(a) hereof involves an underwritten offering and the managing
     underwriter advises 
<PAGE>
 
     IBC in writing, that, in its opinion, the number of IBC Securities intended
     to be included in such Registration Statement exceeds the largest number of
     IBC Securities which can be sold without having an adverse effect on such
     offering, including the price at which such securities can be sold or, if
     in a non-underwritten offering, IBC determines, in its reasonable
     discretion, to limit the number of securities to be sold, (in either case,
     the "Marketable Number"), IBC will include in such Registration Statement
     (i) first, all of the IBC Securities IBC or the Person referred to in the
     first sentence of Section 5.3(a)(i) proposes to sell for its own account,
     (ii) second, all of the IBC Securities requested to be included by holders
     of IBC Securities pursuant to Section 3 of the First Registration Rights
     Agreement, (iii) third, the IBC Securities requested to be included by
     Ralston pursuant to Section 5.3(a) hereof and (iv) fourth, the securities
     requested to be included by other Persons (but if the number of securities
     to be registered pursuant to clause (iv) together with the number of
     securities to be included in such registration pursuant to clauses (i),
     (ii) and (iii) of this Section 5.3(b) exceeds the Marketable Number, the
     number of securities of Persons to be registered pursuant to clause (iv)
     shall be allocated pro rata among such Persons on the basis of the relative
     number of IBC Securities each such Person has requested to be included in
     such registration).

     Section 5.4   Delay of Incidental Registration.  Notwithstanding anything
to the contrary in this Article V, in the event that IBC determines in its
reasonable judgment that it may be advisable to delay filing a Registration
Statement described in Section 5.3 hereof or, to withdraw such Registration
Statement if such Registration Statement has already been filed, IBC may delay
filing such, or withdraw such previously filed, Registration Statement in
accordance with the provisions of Section 5.3(a)(i) hereof.

     Section 5.5   Third Party Registration Rights.  The provisions of this
Article V are in all cases subject to the contractual registration rights
granted by that certain Registration Rights Agreement dated July 23, 1991 (the
"First Registration Rights Agreement") by and among IBC, Mezzanine Investment
Limited Partnership-8, 1987 Merchant Investment Partnership, Merchant LBO Inc.
and GKB IX, L.P.  IBC hereby represents and warrants that the First Registration
Rights Agreement is the only agreement entered into by IBC or any of its
Associates or Affiliates governing the registration of shares of IBC Securities.
IBC will not extend, amend or waive any provisions of the First Registration
Rights Agreement and will not grant any additional registration rights to any
other Person which could limit or restrict the registration rights granted
Ralston pursuant to this Agreement.


                       ARTICLE VI  REGISTRATION EXPENSES

     Section 6.1   Registration Expenses.

          (a)  Subject to Section 5.1(b) of this Agreement, all expenses
     incident to IBC's performance of or compliance with Articles V and VII of
     this Agreement to effect five (5) Demand Registrations will be borne by
     IBC, including, without limitation:
<PAGE>
 
               (i)    all federal registration and filing fees;

               (ii)   subject to Section 7.4, fees and expenses of compliance
     with securities or blue sky laws; provided, however, that IBC will in no
     event be obligated to pay the fees and disbursements of counsel for the
     underwriters or Ralston in connection with blue sky qualifications of the
     IBC Equity under the laws of such jurisdictions as the managing
     underwriter(s) may designate;

               (iii)  printing, messenger, telephone and delivery expenses;

               (iv)   fees and disbursements of legal counsel for IBC;

               (v)    fees and disbursements of all independent certified public
     accountants of IBC;

               (vi)   NASD fees and disbursements of the underwriters; provided,
     however, that in all cases Ralston will pay all costs of discounts,
     commissions, spreads or fees of underwriters, selling brokers, dealer
     managers or similar securities industry professionals relating to the
     distribution of the IBC Equity being sold by Ralston;

               (vii)  fees and expenses of other Persons retained by IBC; and

               (viii) listing or quotation fees and expenses required to be made
     pursuant to Section 7.6 hereof in connection with the Registration
     Statement.

          (b)  Each of IBC and Ralston will pay its own internal expenses
     (including, without limitation, all salaries and expenses of its officers
     and employees performing legal or accounting duties), the expenses of its
     annual audit, rating agency fees and fees and expenses of any Person,
     including special experts retained by IBC or Ralston, respectively.


                     ARTICLE VII   REGISTRATION PROCEDURE

     Section 7.1   Ralston Information.  Ralston will provide IBC with such
information about Ralston and the intended manner of distribution of IBC Equity
and otherwise cooperate with IBC and the underwriter(s) as may be necessary in
the reasonable opinion of IBC to satisfy any obligation of IBC under this
Agreement to register the IBC Equity under federal or state securities laws and
otherwise take actions related thereto.  In the event of the failure of Ralston
to comply with the requirements of the preceding sentence IBC may delay filing
such, and withdraw such previously filed, Registration Statement.  IBC will file
or refile, as the case may be, such Registration Statement promptly following
compliance with such requirements by Ralston; provided, however, that Ralston
will be responsible for any reasonable out of pocket costs which arise out of
such non-compliance.  Ralston will immediately notify IBC upon discovery that
any information provided by Ralston which is included in the prospectus that is
<PAGE>
 
included in a Registration Statement, as then in effect, is untrue in any
material respect, or omits to state any material fact required to be stated
therein or to make the information stated therein not misleading in the light of
the circumstances under which it is presented.

     Section 7.2   Compliance.  Each of Ralston and IBC will comply with all
rules and regulations of the SEC and applicable state securities or blue sky
laws governing the manner of sale of securities in connection with its Transfer
of any of the IBC Equity pursuant to any Registration Statement.

     Section 7.3   Provision of Prospectuses.

          (a)  IBC will furnish to Ralston such number of copies of a summary
     prospectus or other prospectus, including a prospectus subject to
     completion in conformity with the requirements of the Securities Act, and
     such other documents as Ralston may reasonably request in writing, in order
     to facilitate the public sale or other disposition of the IBC Equity
     included in a Registration Statement.

          (b)  At any time when a sale or other disposition of IBC Equity
     pursuant to a Registration Statement is subject to a prospectus delivery
     requirement, IBC will notify Ralston of the occurrence of any event that
     causes the prospectus included in such Registration Statement, as then in
     effect, to include an untrue statement of a material fact or to omit to
     state a material fact required to be stated therein or necessary to make
     the statements therein not misleading in the light of the circumstances
     then existing and IBC will use its best efforts, as expeditiously as
     possible, to either amend the prospectus or otherwise take any actions so
     that use of the previous prospectus may be legally resumed. Upon receipt of
     such a notice, Ralston will immediately discontinue all sales or other
     dispositions of IBC Equity pursuant to the Registration Statement. Ralston
     may resume such sales or dispositions only upon receipt of an amended
     prospectus or after Ralston is advised by IBC that the use of the previous
     prospectus may be legally resumed.

     Section 7.4   Blue Sky Compliance.  IBC will use its best efforts to (a)
register or qualify the IBC Equity included in a Registration Statement under
the securities or blue sky laws of such jurisdictions within the United States
as Ralston reasonably requests and (b) do any and all other acts that may be
reasonably necessary or advisable to enable Ralston to consummate the public
sale or disposition of such securities in such jurisdictions; provided, however,
that IBC is not required to consent to, or take any action that would subject it
to, general service of process or taxation in any jurisdiction where it is not
then so subject, nor qualify to do business in any jurisdiction where it is not
then so qualified.

     Section 7.5   Maintenance of Effectiveness.  IBC will use its best efforts
to prepare and file promptly with the SEC such amendments and supplements to any
Registration Statement, and the prospectus used in connection therewith, as may
be necessary to keep such Registration Statement continuously effective and in
compliance with the Securities Act until the one hundred twentieth (120th) day
following the date on which such Registration Statement becomes effective, or
until all IBC Equity included in such Registration Statement has been sold,
<PAGE>
 
whichever is earlier; provided, however, that IBC will have no obligation under
this Section 7.5 to keep effective any Registration Statement during the period
following any date on which IBC would be required to file audited financial
statements other than the date by which IBC is required to file its next annual
report on Form 10-K containing such required audited financial statements.

     Section 7.6   Listing of IBC Equity.  IBC will use its best efforts to
cause the IBC Equity when issued to be listed on all securities exchanges on
which any securities issued by IBC are then listed, or quoted on all automated
quotation systems on which any such securities of IBC are then quoted,
including, without limitation, entering into appropriate customary agreements
(including a listing application and indemnification agreement in customary
form).

     Section 7.7   Stop-Orders.  IBC will promptly notify Ralston of (a) the
receipt by IBC of any notification with respect to the issuance by the SEC of
any stop-order or order suspending the effectiveness of any Registration
Statement covering any IBC Equity or the initiation of any proceedings for that
purpose, or (b) the receipt by IBC of any notification with respect to the
limitation, restriction or suspension of the offer or sale of IBC Equity in any
jurisdiction in which the IBC Equity was qualified to be sold, or the initiation
of any proceedings for such purpose.  In the event that IBC notifies Ralston of
any such event, Ralston will immediately discontinue all sales or other
dispositions of IBC Equity pursuant to the Registration Statement until such
time that IBC notifies Ralston of the lifting of such stop-order or similar
order; provided, however, that such a stop-order or similar order issued by a
state securities or blue sky administrator will apply only to offers and sales
in such state, unless Ralston is advised otherwise by IBC.  IBC, with the
cooperation of Ralston, will use its best efforts to contest any such
proceedings and to obtain the withdrawal of any such order at the earliest
possible date.


               ARTICLE VIII   INDEMNIFICATION AND CONTRIBUTION

     Section 8.1   Indemnification.

          (a)  Indemnification by Ralston.

               (i)  Ralston agrees to indemnify and hold harmless IBC, its
     Affiliates and Associates (each such Person being hereinafter referred to
     as an "IBC Indemnified Party") from and against all losses, claims,
     damages, liabilities and expenses (including reasonable costs of
     investigation and legal expenses) (each a "Loss") arising out of or based
     upon any untrue statement or alleged untrue statement of a material fact
     contained in any Registration Statement or preliminary, final or summary
     prospectus covering any IBC Equity, or in any amendment or supplement
     thereto, or in any document incorporated by reference into any of the
     foregoing or arising out of or based upon any omission or alleged omission
     to state therein a material fact required to be stated therein or necessary
     to make the statements therein not misleading, but only if, and only to the
     extent, such statement or alleged statement or omission or alleged omission
     was made in reliance upon and in conformity with written information
     furnished to IBC or its 
<PAGE>
 
     representatives by or on behalf of Ralston for use in the preparation of
     such Registration Statement, preliminary, final or summary prospectus or
     such amendment or supplement thereto, or such document incorporated by
     reference. This indemnity will be in addition to any liability which
     Ralston may otherwise have. Ralston will also indemnify the underwriter(s),
     selling broker(s), dealer manager(s) and similar securities industry
     professionals participating in the distribution, their officers and
     directors and each Person who Controls such Persons, to the same extent as
     provided above with respect to the indemnification of the IBC Indemnified
     Party.

               (ii)  Ralston also agrees to indemnify and hold harmless any IBC
     Indemnified Party from and against all Losses arising out of any action or
     proceeding brought against any IBC Indemnified Party in connection with the
     distribution or proposed distribution of IBC Equity to the holders of RAL
     Stock; provided, however, that this Section 8.1(a)(ii) shall not apply to
     any Losses for which IBC is responsible as provided in Section 8.1(b) of
     this Agreement.

               (iii) If any action or proceeding (including any governmental
     investigation or inquiry) is brought or asserted against an IBC Indemnified
     Party in respect of which indemnity may be sought from Ralston, such IBC
     Indemnified Party will promptly notify Ralston in writing of the
     commencement of such action and Ralston shall assume the defense thereof
     and have primary control over any related suit or proceeding, including the
     employment of legal counsel and the payment of all expenses in connection
     therewith; provided, however, that the failure of any IBC Indemnified Party
     to give notice as provided herein shall not relieve Ralston of its
     obligations under this Section 8.1(a) except to the extent that Ralston is
     actually materially prejudiced by such failure to give notice.  An IBC
     Indemnified Party shall have the right to participate in and jointly with
     Ralston, to the extent that it may wish, and employ separate counsel
     reasonably satisfactory to such IBC Indemnified Party, provided, however,
     that Ralston will not be liable to such IBC Indemnified Party for any legal
     or other expenses subsequently incurred by such IBC Indemnified Party in
     connection therewith, unless such IBC Indemnified Party shall have been
     advised by counsel that a conflict of interest between such IBC Indemnified
     Party and Ralston is likely to exist in respect of such claim.

          (b)  Indemnification by IBC.

               (i)  IBC agrees to indemnify and hold harmless Ralston and its
     Affiliates and Associates (each such person being hereinafter referred to
     as a "Ralston Indemnified Party") from and against all Losses arising out
     of or based upon any untrue statement or alleged untrue statement of a
     material fact contained in any Registration Statement, preliminary, final
     or summary prospectus covering any IBC Equity, or in any amendment or
     supplement thereto, or in any document incorporated by reference into any
     of the foregoing or arising out of or based upon any omission or alleged
     omission to state therein a material fact required to be stated therein or
     necessary to make the statement therein not misleading, except insofar as
     such Losses arise out of or are based solely upon 
<PAGE>
 
     any such untrue statement or omission or allegation thereof based upon
     written information provided by or on behalf of Ralston for inclusion in
     such Registration Statement, preliminary, final or summary prospectus, or
     such amendment or supplement thereto, or such document incorporated by
     reference; provided, however, that IBC will not be liable in any such case
     to the extent that any such Loss arises out of or is based upon an untrue
     statement or alleged untrue statement or omission or alleged omission made
     in any preliminary prospectus if (A) Ralston failed to send or deliver a
     copy of the final prospectus with or prior to the delivery of written
     confirmation of the sale of the IBC Equity covered by the Registration
     Statement to the Person asserting such Loss, and (B) the final prospectus
     would have corrected such untrue statement or omission and provided,
     further, that IBC will not be liable in any such case to the extent that
     any such Loss arises out of or is based upon an untrue statement or
     omission in the final prospectus, if such untrue statement or omission is
     corrected in an amendment or supplement to the final prospectus and if,
     having previously been furnished by or on behalf of IBC with copies of the
     final prospectus as so amended or supplemented, Ralston thereafter fails to
     deliver such prospectus as so amended or supplemented, prior to or
     concurrently with the sale of the IBC Equity to the Person asserting such
     Loss who purchased such IBC Equity which is the subject thereof. This
     indemnity will be in addition to any liability which IBC may otherwise
     have. IBC will also indemnify the underwriter(s), selling broker(s), dealer
     manager(s) and similar securities industry professionals participating in
     the distribution, their officers and directors and each Person who Controls
     such Persons, to the same extent as provided above with respect to the
     indemnification of the Ralston Indemnified Party.

               (ii) If any action or proceeding is brought against a Ralston
     Indemnified Party in respect of which indemnity may be sought against such
     Ralston Indemnified Party, Ralston will promptly notify IBC in writing of
     the commencement of such action and IBC will assume the defense thereof and
     have primary control over any related suit or proceeding, including the
     employment of legal counsel and the payment of all expenses in connection
     therewith; provided, however, that the failure of any Ralston Indemnified
     Party to give notice as provided herein shall not relieve IBC of its
     obligations under this Section 8.1(b) except to the extent that IBC is
     actually materially prejudiced by such failure to give notice. A Ralston
     Indemnified Party shall have the right to participate in and jointly with
     IBC, to the extent that it may wish, and employ separate counsel reasonably
     satisfactory to such Ralston Indemnified Party, provided, however, that IBC
     will not be liable to such Ralston Indemnified Party for any legal or other
     expenses subsequently incurred by such Ralston Indemnified Party in
     connection therewith, unless such Ralston Indemnified Party shall have been
     advised by counsel that a conflict of interest between such Ralston
     Indemnified and IBC is likely to exist in respect of such claim.

     Section 8.2   Contribution.

          (a)  If the indemnification provided for in Section 8.1 hereof is
     unavailable to an IBC Indemnified Party or Ralston Indemnified Party under
     Section 8.1(a) or Section 
<PAGE>
 
     8.1(b) hereof (other than by reason of the exceptions provided in Sections
     8.1(a) and 8.1(b)) in respect of any Losses referred to therein, then such
     indemnifying party, in lieu of indemnifying such indemnified party, will
     contribute to the amount paid or payable by such indemnified party as a
     result of such Losses in such proportion as is appropriate to reflect the
     relative fault of the indemnifying party, on the one hand, and the
     indemnified party, on the other hand, in connection with the statements or
     omissions which resulted in such Losses, as well as any other relevant
     equitable considerations. The relative fault of the indemnifying party, on
     the one hand, and the indemnified party, on the other hand, shall be
     determined by reference to, among other things, whether the untrue
     statement or alleged untrue statement of a material fact or the omission or
     alleged omission to state a material fact relates to information supplied
     by such indemnified party and each parties' relative intent, knowledge,
     access to information and opportunity to correct or prevent such statement
     or omission. The amount paid or payable by each party as a result of the
     Losses referred to above will be deemed to include, subject to the
     limitations set forth in Section 8.1(b) hereof, any legal or other fees or
     expenses reasonably incurred by such party in connection with investigating
     or defending any action or claim.

          (b)  Notwithstanding the provisions of Section 8.2(a) hereof, no
     Person found to be guilty of fraudulent misrepresentation shall be entitled
     to contribution from any Person who is not found to be guilty of such
     fraudulent misrepresentation.


                           ARTICLE IX   CALL RIGHTS

     Section 9.1   IBC Call.

          (a)  At any time during the one-year period commencing on the fifth
     anniversary date of this Agreement, IBC shall have the right to acquire
     all, but not less than all of the IBC Equity then owned by Ralston at a
     purchase price equal to one-hundred and ten percent (110%) of the IBC
     Market Price of the IBC Equity then owned by Ralston (such right to acquire
     the IBC Equity is referred to as the "IBC Call").  IBC will notify Ralston
     of its election to exercise the IBC Call (a "Call Notice"), which Call
     Notice will contain IBC's notice of election to purchase such shares
     subject to the IBC Call, the purchase price of the shares subject to the
     IBC Call calculated in accordance with this Section 9.1(a), and the date
     estimated for consummation of the purchase and sale (not more than thirty
     (30) days after the date of the Call Notice).  The consummation of the
     purchase and sale pursuant to this Section 9.1(a) will take place no later
     than thirty (30) days after the date specified in the Call Notice, subject
     to the provisions of Section 9.1(b) hereof and subject to any and all
     waiting periods required under any applicable laws or regulations.  IBC may
     assign the right to purchase such shares subject to the IBC Call to any
     Person.  Any rights to IBC Equity arising pursuant to an IBC Call shall
     continue in effect during the term hereof unless extinguished by IBC
     pursuant to a written notice to Ralston affirmatively relinquishing such
     rights.  IBC shall be permitted to relinquish rights to acquire all of the
     IBC Equity subject to an IBC Call.
<PAGE>
 
          (b)  Upon the consummation of a purchase and sale pursuant to Section
     9.1(a) hereof:

               (i)  Ralston will transfer and deliver to IBC, all of its right,
     title and interest in and to the IBC Equity then owned by Ralston, free and
     clear of all liens and encumbrances and will deliver to IBC a
     certificate(s) evidencing the shares sold duly endorsed, or accompanied by
     written instruments of transfer in form satisfactory to IBC, duly executed,
     with evidence of payment of any applicable stock transfer taxes.

               (ii) IBC or its assignee will deliver to Ralston an amount in
     cash equal to the purchase price of the IBC Equity then owned by Ralston as
     set forth in the IBC Call.

          (c)  The IBC Call shall be exercised within one (1) year following the
     expiration of the fifth anniversary date of this Agreement, and shall
     expire if not exercised by such date.

                       ARTICLE X   ADDITIONAL COVENANTS

     Section 10.1  Maintain Listing or Quotation.  IBC hereby covenants and
agrees that it shall use its best efforts to maintain its listing of IBC

Ralston to serve in the 1996 class shall be nominated and elected to an

the term of this Agreement, so long as Ralston owns at least 15% of the IBC

the other would be irreparably damaged if confidential knowledge of its business

                                   EXHIBIT A


     For purposes of Section 11.17 of the Shareholder Agreement by and among
Interstate Bakeries Corporation, Ralston Purina Company and VCS Holding Company,
the following provisions shall apply:

     1.  "Confidential Information" shall include all information provided
heretofore or hereafter by either Ralston or IBC (individually, a "Company" and
collectively, the "Companies") or their representatives, Affiliates, advisors,
officers, directors, employees or agents ("Representatives"), to the other. The
term "Confidential Information" also will include any analyses, studies or other
documents prepared by Representatives of a Company containing or based in whole
or in part on any information furnished to the other.  Confidential Information
shall not include information which (i) becomes generally available to the
public other than as a result of a disclosure in violation hereof by a Company
or its Representatives, (ii) was in the possession of a Company on a non-
confidential basis prior to its disclosure or (iii) becomes available to a
Company on a non-confidential basis from a source other than the other Company,
which source is entitled to make the disclosure without violation of any
obligation of confidentiality to a Company or other party.

     2.  Each Company recognizes and acknowledges the competitive value and the
confidential and proprietary nature of the Confidential Information and the
damage that could result to the other Company if information contained therein
is disclosed to any third party. Each Company agrees that it will not use the
Confidential Information in any manner that is competitive with or detrimental
to the business or operations of the other Company.  Each Company further agrees
that it will not disclose any of the Confidential Information to any 
<PAGE>
 
person or entity without the prior written consent of the other Company;
provided, however, that there may be a disclosure of such information to such of
its Representatives that need to know such information in connection with any
transactions between the Companies or for valid business reasons which do not
otherwise violate the provisions of this agreement. Each Company acknowledges
that its Representatives are bound hereto to the same extent as each Company as
if there were parties hereto, and each Company shall be responsible for any
breach hereof by any of its Representatives.

     3.  Each Company agrees that a breach of the provisions hereof may give
rise to irreparable injury to the other Company that cannot be compensated for
adequately by monetary damages.  Consequently, each Company shall be entitled
from the other Company, in addition to all other remedies available, to
injunctive and other equitable relief to prevent a breach hereof and to secure
the enforcement hereof in any court of competent jurisdiction in the United
States or any state thereof.

     4.  Each Company hereby acknowledges that it is aware, and will advise its
Representatives and financing sources who are informed as to the matters which
are the subject hereof, that the federal and state securities law prohibit any
person who has received material, non-public information concerning the matters
that are related hereto from purchasing or selling securities of the Companies
or from communicating such information to any other person under circumstances
in which it is reasonably foreseeable that such person is likely to purchase or
sell such securities.

     5.  If either Company is requested or becomes legally compelled to disclose
any of the Confidential Information, such Company agrees that it will provide
the other Company with prompt written notice of such request so that the other
Company may seek a protective order.  In the event that such protective order or
other remedy is not obtained, the Company agrees to furnish only that portion of
the Confidential Information and other information that it is legally obligated
to disclose.

     6.  At either Company's request, the other agrees to promptly return or, at
such Company's option, to destroy the Confidential Information and all copies
thereof.  All copies, extracts or other reproductions in whole or in part
thereof shall be destroyed and not retained by the other Company or its
representatives in any form or for any reason, and such destruction shall be
certified in writing to the requesting Company by an authorized officer
supervising such destruction.  All documents, pleadings, court filings,
memoranda, notes and other writings whatsoever prepared by the other Company or
its representatives based on the Confidential Information (except, in the case
of pleadings and court filings, to the extent reasonably required for proper
record keeping purposes) shall be destroyed, and such destruction shall be
certified in writing to the requesting Company by an authorized officer
supervising such destruction.

     7.  If any provision hereof or the application of any such provision to any
person or circumstance is held invalid, illegal or unenforceable for any reason
whatsoever, the remaining provisions and the application of such provision to
other persons or circumstances shall not be affected thereby. To the fullest
extent possible the court finding such provision invalid, illegal or
<PAGE>
 
unenforceable shall modify and construe the provisions as to render it valid and
enforceable as against all persons or entities and to give the maximum possible
protection to each of the Companies and their Representatives within the bounds
of validity, legality and enforceability.

     8.  The provisions hereof shall continue in effect throughout the term of
the Shareholder Agreement.

                          STOCK REPURCHASE AGREEMENT


          THIS STOCK REPURCHASE AGREEMENT ("Repurchase Agreement") is dated as
of April 29, 1997, by and among RALSTON PURINA COMPANY, a Missouri corporation
("RPC"), VCS HOLDING COMPANY, a Delaware corporation ("VCS") (RPC and VCS being
collectively referred to as "Ralston"), and INTERSTATE BAKERIES CORPORATION, a
Delaware corporation ("IBC"). Capitalized terms not defined herein shall have
the meanings set forth in the Ralston and IBC Shareholders Agreement dated July
22, 1995 (the "Agreement"), as modified herein.

          WHEREAS, the Agreement related to the acquisition by Ralston of
16,923,077 shares of common stock of IBC (referred to as the "IBC Equity" in
Section 11.13 of the Agreement) pursuant to the acquisition of Continental
Baking Company ("CBC");

          WHEREAS, Ralston desires to exercise one of its Demand Registrations
to register a certain number of shares of the IBC Equity (the "Offered Shares")
in conjunction with Ralston's offering of between $360,000,000 and $400,000,000
of exchangeable notes (the "Notes"), which will be exchangeable at maturity
three years after issuance for the Offered Shares or cash (the "Notes
Transaction");

          WHEREAS, pursuant to the Agreement, IBC has a right of First Offer
with respect to all, but not less than all, of the Offered Shares but has
notified Ralston of its waiver of such right with respect to the Offered Shares
that are transferred in exchange for the Notes; and

          WHEREAS, notwithstanding IBC's waiver of its right to acquire all of
the Offered Shares, IBC desires to acquire from Ralston, and Ralston desires to
sell to IBC certain of the IBC Equity (not part of the Offered Shares) on the
terms and subject to the conditions as more fully set forth herein.

          NOW, THEREFORE, in consideration of the foregoing and the mutual
covenants and agreements contained herein, and for other good and valuable
consideration, the receipt and sufficiency of which is hereby acknowledged, the
parties hereto agree as follows.


                                   ARTICLE I
                          STOCK REPURCHASE OBLIGATION
                          ---------------------------

          Section 1.1 The Stock Repurchase Obligation. Subject to any
restrictions contained in applicable laws, Ralston and IBC hereby agree that in
connection with the closing of

                                      -1-
<PAGE>
 
the Notes Transaction, Ralston shall sell to IBC and IBC shall repurchase from
Ralston, 1,000,000 shares (the "Repurchase Shares") of the IBC Equity (other
than the Offered Shares) pursuant to the terms and conditions hereof (the
"Repurchase Obligation").

      Section 1.2  Purchase Price.  The aggregate purchase price (the "Purchase
Price") to be paid for all of the Repurchase Shares shall be (a) 1,000,000
multiplied by the initial price per share of the IBC Equity used to set the
exchange rate for the Notes; (b) such aggregate amount in (a) multiplied by .97;
(c) plus an amount equal to dividends declared on the Repurchase Shares but not
paid prior to the Closing Date.

      Section 1.3  Closing of the Purchase.  The closing of the purchase of the
Repurchase Shares shall occur at 10:00 a.m. central time at the offices of
Shook, Hardy & Bacon L.L.P., 1200 Main Street, Suite 3100, Kansas City, Missouri
64105, immediately following the closing of the Notes Transaction (which will
occur in New York City) or at such other place and time as the parties mutually
agree (the "Closing Date").  The parties agree that they shall negotiate in good
faith the rescheduling of the Closing Date (which in no event shall be later
than sixty days after the closing of the Notes Transaction), if necessary to
comply with Regulation M issued pursuant to the Securities Exchange Act of 1934,
as amended.  If the Closing Date is more than five days after the closing of the
Notes Transaction, then IBC shall pay to RPC interest on the Purchase Price
equal to the rate of interest then paid by IBC on its principal bank
indebtedness.

      Section 1.4  Payment.  On the Closing Date, Ralston shall surrender to IBC
its duly endorsed stock certificates representing the Repurchase Shares, free
and clear of all liens and encumbrances whatsoever, and IBC shall pay to Ralston
the Purchase Price in immediately available funds by wire transfer to an account
designated in writing by Ralston to IBC.  Ralston shall deliver the wire
transfer instructions to IBC at least three business days prior to the Closing
Date.

      Section 1.5  Transfer of Title.  Transfer of title to the Repurchase
Shares shall be deemed to occur automatically on the Closing Date, subject to
payment by IBC on such date of the Purchase Price.
