                                                               December 28, 1998
 
Dear Stockholder:
 
    You are cordially invited to attend our special meeting to be held on
Thursday, January 28, 1999, at 9:00 a.m., local time, at the Danbury Ballroom of
the Danbury Hilton, 18 Ridgebury Road, Danbury, Connecticut.
 
    At the special meeting, you will be asked to approve a merger agreement
among The Clorox Company, Pennant, Inc., a wholly-owned subsidiary of Clorox,
and First Brands Corporation. As a result of the proposed merger, you and the
stockholders of Clorox will become the owners of a combined company.
 
    In the merger, each outstanding share of First Brands stock will be
converted into a fraction of a Clorox share with a value equal to $39, provided
the average closing price of Clorox common stock is greater than $80 and less
than or equal to $115 during the ten trading days preceding the fifth trading
day before the date of the merger. If the average closing price of Clorox common
stock is higher than $115 during such ten-day period, you will receive 0.3391 of
a Clorox share for each First Brands share you own. If the average closing price
of Clorox common stock is less than or equal to $80 during such period, you will
receive 0.4875 of a Clorox share for each First Brands share you own.
 
    First Brands' Board of Directors has determined that the merger agreement
and the merger are in the best interest of First Brands and its stockholders.
Accordingly, the Board has by unanimous vote of all directors present approved
the merger agreement and recommends that you vote in favor of the merger
agreement at the special meeting.
 
    At the special meeting, which will also serve as a special meeting in lieu
of an annual meeting, you will also vote on a proposal to elect three directors
for a three-year term (or until completion of the merger, if earlier) and a
proposal to ratify the appointment of KPMG Peat Marwick LLP as independent
accountants for the year ending June 30, 1999 (or until completion of the
merger, if earlier). First Brands' Board of Directors has also unanimously
approved these other two proposals and unanimously recommends that you vote in
favor of each such proposal.
 
    Your participation in the special meeting, in person or by proxy, is
especially important because the items to be voted on are very important to
First Brands and its stockholders. Whether or not you plan to attend the special
meeting in person, on behalf of First Brands and your fellow stockholders, I
urge you to complete, date, sign and promptly return the enclosed proxy card in
the prepaid envelope enclosed to ensure that your shares will be represented at
the special meeting.
 
    We look forward to the successful combination of First Brands and Clorox and
to your continued support as a stockholder of the combined company.
 
                                          Sincerely,
 
                                          /s/ William V. Stephenson

                            ------------------------
 
TO THE STOCKHOLDERS OF FIRST BRANDS CORPORATION:
 
    The special meeting of stockholders (the "Special Meeting") of First Brands
Corporation, a Delaware corporation ("First Brands"), will be held on Thursday,
January 28, 1999 at the Danbury Ballroom of the Danbury Hilton, 18 Ridgebury
Road, Danbury, Connecticut, commencing at 9:00 a.m., local time. At the Special
Meeting, which will also serve as a special meeting in lieu of an annual
meeting, you will be asked to consider and vote upon the following proposals:
 
    (1) approval and adoption of the Agreement and Plan of Merger dated as of
       October 18, 1998 (the "Merger Agreement") among The Clorox Company, a
       Delaware corporation ("Clorox"), Pennant, Inc., a Delaware corporation
       and a direct wholly-owned subsidiary of Clorox ("Merger Sub"), and First
       Brands, a copy of which is attached as Appendix A to the Proxy
       Statement/Prospectus accompanying this notice. The Merger Agreement
       provides for the merger of Merger Sub with and into First Brands (the
       "Merger"), resulting in First Brands becoming a wholly-owned subsidiary
       of Clorox. In the Merger, each outstanding share of First Brands stock
       will be converted into a fraction of a Clorox share with a value equal to
       $39, provided the average closing price of Clorox common stock is greater
       than $80 and less than or equal to $115 during the ten trading days
       preceding the fifth trading day before the date of the Merger. If the
       average closing price of Clorox common stock is higher than $115 during
       such period, each outstanding share of First Brands stock will be
       converted into 0.3391 of a Clorox share. If the average closing price of
       Clorox common stock is less than or equal to $80 during such period, each
       outstanding share of First Brands stock will be converted into 0.4875 of
       a Clorox share;
 
    (2) election of three directors to serve a term of three years (or until
       consummation of the Merger, if earlier);
 
    (3) ratification of the appointment by the First Brands board of directors
       of KPMG Peat Marwick LLP as independent accountants for the year ending
       June 30, 1999 (or until consummation of the Merger, if earlier); and
 
    (4) transaction of such other business as may properly be brought before the
       Special Meeting or any adjournment thereof.
 
    AFTER CAREFUL CONSIDERATION, YOUR BOARD OF DIRECTORS HAS BY UNANIMOUS VOTE
OF ALL DIRECTORS PRESENT DETERMINED THAT THE EXCHANGE RATIO IS FAIR TO AND IN
THE BEST INTERESTS OF FIRST BRANDS AND ITS STOCKHOLDERS. THE BOARD RECOMMENDS
THAT YOU VOTE FOR APPROVAL AND ADOPTION OF THE MERGER AGREEMENT AT THE SPECIAL
MEETING.
 
    Your Board of Directors has also unanimously approved each of the other
proposals to be considered at the Special Meeting and unanimously recommends
that stockholders vote in favor of each such proposal.
 
    Please read the accompanying Proxy Statement/Prospectus carefully for a
description of the Merger Agreement.

                      QUESTIONS & ANSWERS ABOUT THE MERGER
 
<TABLE>
<C>        <S>
   Q:      WHY ARE THE TWO COMPANIES PROPOSING THE
           MERGER? HOW WILL I BENEFIT?
 
   A:      This merger means that you will have a
           stake in one of the nation's leading
           consumer goods companies. The combined
           company will be a major manufacturer and
           marketer of diverse consumer goods in
           the United States and internationally.
           The product lines will include laundry
           additives, household cleaners, plastic
           bags, plastic wraps, cat litter, auto
           care products and home fireplace
           products. It is anticipated that
           combined annual sales will exceed $4
           billion. Overall, Clorox believes that
           the merger will provide added value to
           all its stockholders. Clorox notes that
           achieving its goals with respect to the
           merger is subject to certain risks as
           discussed in the section on "Risk
           Factors." To review the reasons for the
           merger in greater detail, see page 27.
 
   Q:      WHEN IS THE FIRST BRANDS SPECIAL
           MEETING, AND WHAT ARE THE PROPOSALS I AM
           BEING ASKED TO VOTE UPON AT THE MEETING?
 
   A:      The Special Meeting of First Brands
           stockholders will take place on January
           28, 1999. At that meeting you will be
           asked to vote on three proposals: (a)
           approval and adoption of the merger
           agreement, (b) election of directors to
           serve a term of three years (or until
           consummation of the Merger, if earlier)
           and (c) ratification of the appointment
           of KPMG Peat Marwick LLP as independent
           auditors for the year ending June 30,
           1999 (or until consummation of the
           Merger, if earlier).
 
   Q:      WHAT VOTE IS REQUIRED?
 
   A:      To approve the merger, a vote reflecting
           two thirds of the shares entitled to
           vote at the Special Meeting is required.
           Directors are elected by a plurality of
           the votes represented at the Special
           Meeting if a quorum (holders of a
           majority of the outstanding shares) is
           present at such meeting. The
           ratification of the appointment of
           independent auditors requires the
           approval of a majority of the votes
           represented at the Special Meeting,
           assuming that a quorum is present.
 
   Q:      WHAT DO I NEED TO DO NOW?
 
   A:      Just mail your signed proxy card in the
           enclosed return envelope as soon as
           possible, so that your shares may be
           represented at the Special Meeting. The
           Board of Directors of First Brands
           recommends voting in favor of the
           approval of the merger agreement and the
           merger and also recommends that you vote
           in favor of the other proposals.
 
   Q:      WHAT DO I DO IF I WANT TO CHANGE MY
           VOTE?
 
   A:      Just send in a later-dated, signed proxy
           card to the Secretary of First Brands
           before the meeting or attend the meeting
           in person and vote.
 
   Q:      SHOULD I SEND IN MY STOCK CERTIFICATES
           NOW?
 
   A:      No. After the merger is completed,
           Clorox will send First Brands
           stockholders written instructions for
           exchanging their share certificates.
 
   Q:      PLEASE EXPLAIN WHAT I WILL RECEIVE IN
           THE MERGER.
 
   A:      You will receive for each First Brands
           share you own a fraction of a share of
           Clorox common stock, which will be
           determined as follows:
 
        - If the average closing price of Clorox
          common stock during the ten trading days
          preceding the fifth trading day before
          the date of the merger is greater than
          $80 and less than or equal to $115, you
          will receive a fraction of a share of
          Clorox common stock with a value of $39
          based on the average closing price during
          that ten-day period. For example, if the
          average closing price during that period
          for Clorox common stock is $100 per
          share, you will receive 0.3900 of a
          Clorox share for each First Brands share
          you own.
</TABLE>

<PAGE>
 
<TABLE>
<C>        <S>
        - If the average closing price of Clorox
          common stock during the ten-day period is
          less than or equal to $80, you will
          receive 0.4875 of a Clorox share for each
          First Brands share you own. For example,
          if the average closing price of Clorox
          common stock during that period is $75,
          you will receive 0.4875 of a share of
          Clorox common stock for each First Brands
          share you own. That fraction of a Clorox
          share would have a value of $36.56 based
          on the average closing price during the
          ten-day period.
 
        - If the average closing price of Clorox
          common stock during the ten-day period is
          greater than $115, you will receive
          0.3391 of a share of Clorox common stock
          for each First Brands share you own. For
          example, if the average closing price
          during that period for Clorox common
          stock is $120, you will receive 0.3391 of
          a share of Clorox common stock for each
          First Brands share you own. That fraction
          of a Clorox share would have a value of
          $40.69 based on the average closing price
          during the ten-day period.
 
           Because the fraction of a Clorox share
           that you will receive is fixed five
           trading days before the date of the
           merger, the actual value on the date of
           the merger of the Clorox shares you will
           receive may vary from the value of those
           shares on the date the fraction is fixed
           if Clorox's stock price on the date of
           the merger is different from the average
           closing price during the ten-day period.
 
   Q:      WILL CLOROX ISSUE FRACTIONAL SHARES TO
           FIRST BRANDS STOCKHOLDERS?
 
   A:      Clorox will not issue fractional shares
           in the merger. As a result, First Brands
           stockholders will receive a cash payment
           based on the closing price of Clorox
           common stock on the last trading day
           before the merger multiplied by the
           remaining fraction of a share of Clorox
           common stock they would otherwise be
           entitled to receive.
   Q:      WHAT HAPPENS TO MY FUTURE DIVIDENDS?
 
   A:      We expect no changes in Clorox's or
           First Brands' dividend policies before
           the merger. After the merger, we expect
           the initial annual dividend rate to be
           $1.44 per share of Clorox common stock,
           which is equivalent to the current
           annual dividend payment to Clorox
           stockholders. The payment of dividends
           by Clorox in the future, however, will
           depend on business conditions, its
           financial condition and earnings, and
           other factors.
 
   Q:      WHEN DO YOU EXPECT THE MERGER TO BE
           COMPLETED?
 
   A:      We expect to complete the merger within
           three days after the Special Meeting of
           First Brands stockholders.
 
   Q:      WHAT ARE THE TAX CONSEQUENCES OF THE
           MERGER TO FIRST BRANDS STOCKHOLDERS?
 
   A:      We expect that for U.S. federal income
           tax purposes the exchange of shares will
           be tax-free to First Brands
           stockholders, except for taxes with
           respect to cash received for any
           fractional shares of Clorox common
           stock. To review the federal income tax
           consequences to First Brands
           stockholders in greater detail, see page
           40.

                             REASONS FOR THE MERGER
 
    The First Brands board of directors considered a number of factors in
determining to approve the merger and recommend it to its stockholders. These
considerations are described below under "The Merger--Reasons for the Merger;
Recommendations of the First Brands Board."
 
                              THE SPECIAL MEETING
 
    The Special Meeting of First Brands stockholders will take place on January
28, 1999. At that meeting, which will also serve as a special meeting in lieu of
an annual meeting, you will be asked to vote on three proposals:
 
    - approval and adoption of the merger agreement;
 
    - election of directors for a term of three years (or until consummation of
      the merger, if earlier); and
 
    - ratification of the appointment of KPMG Peat Marwick LLP as independent
      auditors for the year ending June 30, 1999 (or until consummation of the
      merger, if earlier).
 
                                 VOTE REQUIRED
 
    To approve the merger, a vote reflecting two thirds of the shares entitled
to vote at the Special Meeting is required. Directors are elected by a plurality
of the votes represented at the Special Meeting if a quorum (holders of a
majority of the outstanding shares) is present at such
 
                                       3
<PAGE>
meeting. The ratification of the appointment of independent auditors requires
the approval of a majority of the votes represented at the Special Meeting of
stockholders assuming that a quorum is present.
 
                         RECOMMENDATION TO STOCKHOLDERS
 
    The First Brands board of directors has determined that the merger agreement
and the merger are in the best interest of First Brands and its stockholders.
Accordingly, the First Brands board of directors has by unanimous vote of all
directors present approved the merger agreement and recommends that you vote in
favor of the merger agreement at the Special Meeting. The First Brands board of
directors has also unanimously approved each of the other proposals to be
considered at the Special Meeting and unanimously recommends that you vote in
favor of each such proposal.
 
                                   THE MERGER
 
    The merger agreement is attached as Appendix A to this Proxy
Statement/Prospectus. We encourage you to read the merger agreement as it (and
not this Proxy Statement/Prospectus) is the legal document that governs the
merger.
 
WHAT YOU WILL RECEIVE IN THE MERGER. (SEE PAGE 37)
 
    You will receive for your shares of First Brands common stock the right to
receive whole shares of Clorox common stock, and cash in lieu of any fractional
shares of Clorox common stock. The exchange ratio will depend on the average
closing price of Clorox common stock on the New York Stock Exchange over the ten
trading days preceding the fifth trading day before the date of the merger, as
follows:
 
    - If the average closing price over such period is more than $80 but less
      than or equal to $115, the exchange ratio will be $39 divided by the
      average closing price over such period (that is, you will receive
      approximately $39 in value (based on the average closing price) of Clorox
      common stock for each share of First Brands common stock);
 
    - If the average closing price over such period is less than or equal to
      $80, the exchange ratio will be 0.4875 of a share of Clorox common stock
      for each share of First Brands common stock;
 
    - If the average closing price is greater than $115, the exchange ratio will
      be 0.3391 of a share of Clorox common stock for each share of First Brands
      common stock.
 
    These ratios are referred to collectively throughout this Proxy
Statement/Prospectus as the "Exchange Ratio."
 
    Clorox will not issue fractional shares in the merger. Instead, you will
receive cash, without interest, equal to (1) the fraction of a share to which
you are entitled, multiplied by (2) the closing price of Clorox common stock on
the last trading day before the date of the merger, rounded up to the nearest
whole cent.
 
    YOU SHOULD NOT SEND IN YOUR STOCK CERTIFICATES FOR EXCHANGE UNTIL INSTRUCTED
TO DO SO AFTER THE MERGER IS COMPLETED. YOU WILL BE SENT A SEPARATE MAILING TO
EXCHANGE YOUR CERTIFICATES AT THAT TIME.
 
INTERESTS OF CERTAIN PERSONS IN THE MERGER. (SEE PAGE 34)
 
    You should note that certain directors and executive officers of First
Brands may have interests in the merger that are different from, and in addition
to, the interests of First Brands stockholders generally.
 
CONDITIONS TO THE MERGER. (SEE PAGE 49)
 
    We will complete the merger only if the conditions set forth in the merger
agreement are satisfied or (in some cases) waived. These conditions include,
among others, the following:
 
    - approval of the merger by the stockholders of First Brands;
 
    - declaration of effectiveness of the Registration Statement of which this
      Proxy Statement/Prospectus forms a part;
 
    - receipt of letters from Clorox's and First Brands' accountants stating
      that the
 
                                       4
<PAGE>
      merger will qualify as a "pooling of interests" for accounting purposes;
 
    - receipt of legal opinions that the merger will be treated as a tax-free
      reorganization under Section 368(a) of the Internal Revenue Code of 1986,
      as amended;
 
    - absence of any change in either Clorox or First Brands or any of their
      subsidiaries which has had or may have a material adverse effect on
      Clorox's or First Brands' business taken as a whole;
 
    - absence of any law, court order or litigation by a governmental agency
      prohibiting or seeking to prohibit the merger;
 
    - the representations and warranties of each of Clorox and First Brands
      contained in the merger agreement remaining true at the closing unless the
      failure for this to occur would not have a material adverse effect on the
      party whose representations and warranties are not true; and
 
    - each of Clorox and First Brands having complied in all material respects
      with their covenants under the merger agreement.
 
    At any time before the merger, to the extent legally allowed, the board of
directors of Clorox or First Brands may waive compliance with any of the
conditions contained in the merger agreement without the approval of Clorox
stockholders or First Brands stockholders.
 
    The merger is also subject to the following additional condition, which was
satisfied before the date we mailed this Proxy Statement/ Prospectus:
 
    - expiration of the waiting period during which the U.S. regulatory
      authorities review the merger under the Hart-Scott-Rodino Antitrust
      Improvements Act of 1976, as amended.
 
TERMINATION OF THE MERGER AGREEMENT. (SEE PAGE 51)
 
    The merger agreement may be terminated under the following circumstances:
    - by mutual consent of Clorox and First Brands;
 
    - by either Clorox or First Brands if the merger has not been consummated by
      June 30, 1999 (so long as the failure of the merger to close by such date
      is not due to the party who exercises this right to terminate having
      failed to fulfill its obligations under the merger agreement);
 
    - by either Clorox or First Brands if a court or governmental entity has
      issued a final order prohibiting the merger;
 
    - by either Clorox or First Brands if the stockholders of First Brands do
      not approve the merger;
 
    - by Clorox if the First Brands board of directors withdraws, changes or
      modifies its recommendation in favor of the merger in a manner adverse to
      Clorox or recommends to the First Brands stockholders an alternative
      transaction;
 
    - by First Brands if, after having received a superior proposal, it
      withdraws its recommendation to approve the merger agreement because it
      has determined that its fiduciary duties require it to do so; or
 
    - by First Brands or Clorox if the other party has breached any
      representation, warranty or covenant in the merger agreement which would
      not be able to be cured by the breaching party prior to closing.
 
TERMINATION FEE. (SEE PAGE 52)
 
    First Brands must pay Clorox a fee of $52 million in cash if the agreement
is terminated in the following circumstances:
 
    - if the First Brands board of directors withdraws, changes or modifies its
      recommendation in favor of the merger in a manner adverse to Clorox or
      resolves to take such action;
 
                                       5
<PAGE>
    - if the First Brands board of directors recommends a tender offer or merger
      proposal made by a third party to the First Brands stockholders; or
 
    - if a tender offer or exchange offer for 15% or more of the outstanding
      shares of First Brands common stock is commenced (other than by Clorox or
      an affiliate of Clorox) and the First Brands board of directors recommends
      that the First Brands stockholders tender their shares in such tender or
      exchange offer.
 
NON-SOLICITATION OF COMPETING TRANSACTIONS. (SEE PAGE 47)
 
    The merger agreement generally restricts First Brands' ability to entertain
or encourage any alternative transactions for the sale of the company with third
parties beyond what is required by the First Brands board's fiduciary duties.
First Brands is required to communicate to Clorox the terms of any superior
proposal it receives from a third party unless the First Brands board of
directors believes that its fiduciary duties require that it not do so.
 
REGULATORY APPROVALS. (SEE PAGE 39)
 
    Clorox and First Brands are both required to make filings with or obtain
approvals from certain United States and international regulatory authorities in
connection with the merger, including United States antitrust authorities. The
waiting period during which the U.S. regulatory authorities review the merger
under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended,
expired on December 10, 1998. We believe that all other material notifications,
filings and approvals have been made or obtained, or will be made or obtained
prior to the date of the merger.
 
FAIRNESS OPINION OF LEHMAN BROTHERS (SEE PAGE 28)
 
    Lehman Brothers has acted as financial advisor to First Brands in connection
with the merger and has delivered a written opinion, dated October 18, 1998, to
the First Brands board that the Exchange Ratio was fair to First Brands
stockholders, from a financial point of view, on that date. The First Brands
board of directors considered this opinion in deciding to approve and recommend
the merger. A copy of this opinion, which describes the assumptions made,
matters considered and limitations on the reviews undertaken by Lehman Brothers,
is attached as Appendix B to this Proxy Statement/ Prospectus. We encourage you
to read and consider this opinion.
 
NO DISSENTERS' RIGHTS. (SEE PAGE 40)
 
    Holders of First Brands common stock are not entitled under Delaware law to
an appraisal of the value of their shares in connection with the merger.
 
MATERIAL FEDERAL INCOME TAX CONSEQUENCES. (SEE PAGE 40)
 
    The obligations of both companies to complete the merger are conditioned
upon the receipt by each company of an opinion of its counsel that, generally,
for U.S. federal income tax purposes, the merger will qualify as a
reorganization under the Internal Revenue Code of 1986, as amended. Provided the
merger so qualifies, First Brands stockholders will not recognize any gain or
loss upon the exchange of their First Brands common stock for Clorox common
stock (except with respect to cash received in lieu of a fractional share
interest of Clorox common stock). In the event that Clorox or First Brands is
unable to obtain these opinions, each of the parties is permitted under the
merger agreement to waive the receipt of the opinions as a condition to its
obligation to complete the merger. As of the date of this Proxy
Statement/Prospectus, neither Clorox nor First Brands intends to waive the
receipt of these opinions as a condition to its obligation to complete the
merger. In the event that Clorox or First Brands fails to obtain these opinions,
and either Clorox or First Brands determines to waive receipt of an opinion as a
condition to the completion of the merger, First Brands will resolicit the votes
of its stockholders to approve completion of the merger.
 
    TAX MATTERS ARE VERY COMPLICATED, AND THE TAX CONSEQUENCES OF THE MERGER TO
YOU WILL DEPEND ON THE FACTS OF YOUR OWN SITUATION. YOU SHOULD CONSULT YOUR TAX
ADVISORS FOR A FULL

UNDERSTANDING OF THE TAX CONSEQUENCES OF THE MERGER TO YOU.
 
ACCOUNTING TREATMENT
 
    Clorox and First Brands expect the merger will qualify as a "pooling of
interests," which means that Clorox and First Brands will be treated as if they
had always been combined for accounting and financial reporting purposes. The
availability of this accounting treatment is a condition to the merger.
 
                                  RISK FACTORS
 
    You should carefully consider the risk factors under the caption "Risk
Factors" on page 13. Such risk factors include, among other things, that Clorox
may not be able to integrate the business of First Brands successfully, the
stockholders of First Brands will not receive a fixed value of Clorox common
stock in the merger under all circumstances and Clorox may incur substantial
expenses related to the merger.
 
                           FORWARD-LOOKING STATEMENTS
 
    Clorox and First Brands have made forward-looking statements in this
document and in the documents to which we have referred you. These statements
are subject to risks and uncertainties, and therefore may not prove to be
correct. Forward-looking statements include assumptions as to how Clorox may
perform after the merger, and, accordingly, it is uncertain whether any of the
events anticipated by the forward-looking statements will transpire or occur, or
if any of them do so, what impact they will have on the results of operations
and financial condition of Clorox or the price of its stock. See page 18 for
further details.
 
    When we use words like "believes," "expects," "anticipates" or similar
expressions, we are making forward-looking statements. For those statements,
Clorox and First Brands claim the protection of the safe harbor for forward-
looking statements contained in the Private Securities Litigation Reform Act of
1995.

    The following selected unaudited pro forma combined condensed financial
information is derived from the unaudited pro forma combined condensed financial
statements and notes thereto appearing elsewhere in this Proxy
Statement/Prospectus, which give effect to the merger as a pooling of interests
transaction, and you should read it in conjunction with such unaudited pro forma

    For purposes of the unaudited pro forma combined condensed financial

    The unaudited pro forma combined condensed financial information is
presented for comparative purposes only and does not purport to be indicative of
the operating results or financial position that would have occurred had the
merger been consummated at the beginning of the periods presented, nor is such
information necessarily indicative of the future operating results or financial

COMPARATIVE PER SHARE INFORMATION
 
    The following table summarizes per share information for Clorox and First
Brands on a historical, pro forma combined and equivalent basis. The pro forma
information gives effect to the merger accounted for on a "pooling of interests"
basis, assuming that 0.3545 of a share of Clorox common stock (an average per
share price of Clorox common stock of $110 during the measurement period) was
issued for each share of First Brands common stock outstanding. You should read
this information together with the historical financial statements (and related
notes) included in the annual reports on Form 10-K and other information that
each of First Brands and Clorox has filed with the Securities and Exchange
Commission and which are incorporated herein by reference. See "Where You Can
Find More Information" on page 75. You should also read this information in
connection with the pro forma combined condensed financial information set forth
starting on page 58. You should not rely on the pro forma combined condensed
financial information as being indicative of the results that would have been
achieved had the companies been combined at a prior date or the future results
that the combined company will experience after the merger.

    Clorox common stock is currently traded on the New York Stock Exchange and
the Pacific Exchange under the symbol "CLX." First Brands common stock is
currently traded on the New York Stock Exchange under the symbol "FBR."
 
    On October 16, 1998, the last trading day prior to the public announcement
of the merger agreement, the closing sale price of Clorox common stock was
$99.75 per share, and the closing sale price of First Brands common stock was
$23.63 per share. Based on the terms of the merger agreement, the value of
Clorox common stock that would have been received on that date was $39 for each
share of First Brands common stock.
 
    Because the Exchange Ratio will be fixed five trading days prior to the
merger and because the market price of Clorox common stock is subject to
fluctuation, the market value of the shares of Clorox common stock that holders
of First Brands common stock will receive in the merger may increase or decrease
prior to and following the merger. WE URGE HOLDERS OF FIRST BRANDS COMMON STOCK
TO OBTAIN CURRENT MARKET QUOTATIONS OF CLOROX COMMON STOCK AND FIRST BRANDS
COMMON STOCK. NO ASSURANCE CAN BE GIVEN AS TO THE FUTURE PRICES OR MARKETS FOR
CLOROX COMMON STOCK OR FIRST BRANDS COMMON STOCK.
 
    Clorox declared dividends of approximately $132 million in fiscal year 1998,
or approximately 44% of Clorox's 1998 consolidated earnings. Per share dividends
declared of $1.28 in fiscal year 1998 represent an increase of approximately
10.3% from per share dividends of $1.16 in fiscal year 1997. Anticipated fiscal
year 1999 per share dividends are $1.44, a 12.5% increase over fiscal year 1998.
Following the merger, payment of cash dividends by Clorox in respect of Clorox
common stock will depend on Clorox's financial condition, results of operations
and any other factors the Clorox board of directors may consider relevant.

                                  RISK FACTORS
 
    IN ADDITION TO THE OTHER INFORMATION INCLUDED IN THIS PROXY
STATEMENT/PROSPECTUS, YOU SHOULD CAREFULLY CONSIDER THE FOLLOWING RISK FACTORS
IN DETERMINING WHETHER TO VOTE TO APPROVE THE MERGER. THESE MATTERS SHOULD BE
CONSIDERED IN CONJUNCTION WITH THE OTHER INFORMATION INCLUDED OR INCORPORATED BY
REFERENCE IN THIS PROXY STATEMENT/PROSPECTUS.
 
UNCERTAINTIES ASSOCIATED WITH THE INTEGRATION OF FIRST BRANDS AND ACHIEVEMENT OF
  COST SAVINGS
 
    The merger will present challenges to management, including the integration
of the operations, technologies and personnel of Clorox and First Brands, and
special risks, including possible unanticipated liabilities, unanticipated
costs, and diversion of management attention.
 
    There can be no assurance that Clorox will be able to successfully integrate
or profitably manage First Brands' businesses. In addition, there can be no
assurance that, following the transaction, First Brands' businesses will achieve
sales levels, profitability, cost savings or synergies that justify the
investment made or that the acquisition will be accretive to earnings in any
future period.
 
SUBSTANTIAL EXPENSES RESULTING FROM THE MERGER
 
    Clorox and First Brands estimate they will incur combined aggregate direct
transaction costs of approximately $15.5 million associated with the merger,
consisting of transaction fees for investment bankers, attorneys, accountants,
and other related costs. These nonrecurring transaction costs will be charged to
operations upon consummation of the merger. It is expected that following the
merger, the combined company will incur additional nonrecurring costs, currently
estimated to be approximately $125 million, including non-cash charges estimated
at $30 million. There can be no assurance that the combined company will not
incur additional charges in excess of $125 million to reflect costs associated
with the merger.
 
ADJUSTABLE EXCHANGE RATIO
 
    The merger agreement provides for adjustments to the Exchange Ratio between
First Brands common stock and Clorox common stock based upon the average of the
closing prices of Clorox common stock on the New York Stock Exchange ("NYSE")
Composite Transaction Tape during the ten trading days preceding the fifth
trading day prior to the date of the merger (the "Clorox Average Share Price").
These adjustments are designed so that you will receive $39 in value of Clorox
common stock (as measured by the Clorox Average Share Price) for each share of
First Brands common stock exchanged in the merger, so long as the Clorox Average
Share Price is greater than $80 and less than or equal to $115. However, if the
Clorox Average Share Price is above $115, the Exchange Ratio will be fixed at
0.3391, so that the value of the Clorox common stock that you will receive in
the merger (measured by the Clorox Average Share Price) will be greater than
$39. In addition, if the Clorox Average Share Price is less than or equal to
$80, the Exchange Ratio will be fixed at 0.4875, so that the value of Clorox
common stock that you will receive in the merger (measured by the Clorox Average
Share Price) will be less than $39.
 
    At the time of the special meeting, you will not know the exact value of the
Clorox common stock you will receive when the merger is completed, because the
price of Clorox common stock at the time of the merger is likely to be different
from the Clorox Average Share Price, which could increase or decrease the actual
value of the Clorox common stock that you will receive from the value that was
calculated based on the Clorox Average Share Price. The price of Clorox common
stock may change based upon changes in the business, operations and prospects of
Clorox, general market and economic conditions, regulatory considerations and
other factors. We urge you to obtain current market quotations for Clorox common
stock and First Brands common stock and to call the Director of Investor
Relations of Clorox or the Secretary of First Brands at (510) 271-2150 or (203)
731-2300, respectively,

at any time after December 21, 1998 for current information on the Clorox
Average Share Price and the Exchange Ratio.
 
RISKS ASSOCIATED WITH INTERNATIONAL OPERATIONS
 
    Clorox believes that its international sales, which were 18% of net sales in
fiscal year 1998, are likely to increase as a percentage of its total sales, as
a result of both internal expansion and the addition of First Brands'
international operations. As a result, Clorox will be increasingly subject to
the risks associated with foreign operations, including economic or political
instability in its overseas markets, shipping delays and fluctuations in foreign
currency exchange rates that may make its products more expensive in its foreign
markets, all of which could have a significant impact on Clorox's ability to
sell its products on a timely and competitive basis in foreign markets and may
have a material adverse effect on Clorox's results of operations or financial
position. Clorox seeks to limit its foreign currency exchange risks through the
use of foreign currency forward contracts when practical, but there can be no
assurance that this strategy will be successful. In addition, Clorox's
international operations are subject to the risk of new and different legal and
regulatory requirements in local jurisdictions, potential difficulties in
staffing and managing local operations, credit risk of local customers and
distributors, and potentially adverse tax consequences.
 
FAILURE TO QUALIFY FOR POOLING OF INTERESTS ACCOUNTING TREATMENT MAY IMPACT
  REPORTED OPERATING RESULTS
 
    The obligations of Clorox and First Brands to complete the merger are
subject to a number of conditions, one of which is that each of them receive an
opinion from its accountants that the merger qualifies for "pooling of
interests" accounting treatment under U.S. generally accepted accounting
principles. Under pooling of interests accounting treatment, the accounts of
Clorox will be combined with those of First Brands at their historical carrying
amounts, and Clorox's financial statements for all prior periods will be
restated to reflect the accounts of Clorox as if the two companies had been
combined for all periods.
 
    As part of the process to qualify for pooling of interests accounting
treatment for the merger, Clorox plans to discontinue a previously announced
share repurchase program. Clorox will also need to issue additional shares of
its common stock to third parties. Such share issuance and any issuance of
shares pursuant to Clorox stock incentive and option plans will have a potential
dilutive effect on Clorox stockholders.
 
    Nevertheless, if, after consummation of the merger, events occur that cause
the merger to be deemed no longer to qualify for pooling of interests accounting
treatment, the purchase method of accounting would be applied. Under that
method, the estimated fair value of Clorox common stock issued in the merger
would be recorded as the cost of acquiring the business of First Brands. That
cost would be allocated to the individual assets acquired and liabilities
assumed according to their respective fair values, with the excess of the
estimated fair value of Clorox common stock over the fair value of net assets
acquired recorded as goodwill, to be amortized over a period of up to 40 years.
The estimated fair value of Clorox common stock to be issued in the merger is
substantially in excess of the amount at which the historical net book value at
which the assets of First Brands are carried in its accounts. Therefore,
purchase accounting treatment could have a material adverse effect on the
reported operating results of the combined company as compared to pooling of
interests accounting treatment because of required charges to Clorox's earnings
for amortization of goodwill required by the purchase accounting treatment.

FLUCTUATIONS IN QUARTERLY OPERATING RESULTS
 
    Although Clorox's recent historical operating results have improved when
compared with the same quarter in the previous fiscal year, there can be no
assurance that such quarter-to-quarter comparisons will continue to improve, or
that if any improvement is shown, the degree of improvement will meet investors'
expectations. In addition, sales volume growth, whether due to acquisitions or
to internal growth, can place burdens on Clorox's management resources and
financial controls which, in turn, can have a negative impact on operating
results. Clorox's quarterly operating results will be influenced by a host of
factors, which include the following: the seasonality of its products; the
extent of competition; the degree of market acceptance of new products and line
extensions; the mix of products sold in a given quarter; changes in pricing
policies by Clorox and by its competitors; acquisition costs and restructuring
and other charges associated with acquisitions, including the First Brands
merger; the ability of Clorox to develop, introduce and market successful new
products and line extensions; the ability of Clorox to control its internal
costs and costs of its raw materials and packaging materials; Clorox's success
in expanding its international operations; changes in Clorox's strategy;
personnel changes; and general economic conditions. To a certain extent, Clorox
sets its expense levels in anticipation of future revenues. If actual revenue
falls short of expectations, operating results are likely to be adversely
affected. Because of all of these factors, Clorox believes that
quarter-to-quarter comparisons of its results of operations should not be relied
upon as indications of future performance.
 
    Future announcements concerning Clorox or its competitors, quarterly
variations in operating results, the introduction of new products and line
extensions or changes in product pricing policies by Clorox or its competitors,
changes in earnings estimates by analysts, or changes in accounting policies,
among other factors, could cause the market price of Clorox common stock to
fluctuate substantially and have an adverse effect on the price of Clorox common
stock. In addition, stock markets have experienced price and volume volatility,
and such volatility in the future could have an adverse impact on Clorox's
market price.
 
IMPORTANCE OF NEW PRODUCTS
 
    In most categories in which Clorox competes, there are frequent
introductions of new products and line extensions. Accordingly, an important
factor in Clorox's future performance will be its ability to identify emerging
consumer and technological trends and to maintain and improve the
competitiveness of its products. However, there can be no assurance that Clorox
will successfully achieve those goals. Continued product development and
marketing efforts are subject to all the risks inherent in the development of
new products and line extensions, including development delays, the failure of
new products and line extensions to achieve anticipated levels of market
acceptance, and the cost of failed product introductions.
 
YEAR 2000 COMPLIANCE
 
    Many financial information and operations systems used today may be unable
to interpret dates after December 31, 1999 because these systems allow only two
digits to indicate the year in a date. Consequently, these systems are unable to
distinguish January 1, 2000 from January 1, 1900, which could have adverse
consequences on the operations of an entity and the integrity of information
processing. This potential problem is referred to as the "Year 2000" or "Y2K"
issue.
 
    In 1997, Clorox established a corporate-wide program to address Y2K issues.
This effort is comprehensive and encompasses software, hardware, electronic data
interchange, networks, PCs, manufacturing and other facilities, embedded chips,
century certification, supplier and customer readiness, contingency planning,
and domestic and international operations. Clorox's program to address the Y2K
issue is currently on schedule and is more than 60% complete as of September 30,
1998. Clorox has replaced or upgraded most of its critical business applications
and systems and has begun the century
 
                                       15
<PAGE>
testing phase for these critical technology systems. The target date to repair
or replace the remaining critical business information systems is March 31,
1999. Clorox is assessing its plant floor systems and equipment, and the target
date to complete manufacturing plant floor and facilities efforts is September
30, 1999. Clorox has prioritized its third-party relationships as critical,
severe or sustainable, has completed the assessment phase for third parties
(except for assessment of its key customers, which is scheduled to be complete
in March 1999), has requested a Y2K contract warranty in many new key contracts
and is developing contingency plans for critical third parties, including key
customers, suppliers and other service providers.
 
    If necessary modifications and conversions by Clorox are not made on a
timely basis, or if key third parties are not Y2K compliant, Y2K problems could
have a material adverse effect on Clorox's operations. Clorox's most reasonably
likely worst case scenario is a regional utility failure that would interrupt
manufacturing operations and distribution centers in the affected region. To
mitigate this risk, and to address the possible uncertainty of whether Clorox
will be able to solve all potential Y2K issues, Clorox has begun contingency
planning for its critical operations, including key third-party relationships,
and will require written contingency plans for these areas. Clorox expects to
complete all of its contingency planning by June 30, 1999.
 
    Y2K costs are expensed as incurred and funded through operating cash flows.
Through September 30, 1998, Clorox has expensed incremental remediation costs of
$17.1 million with remaining incremental remediation costs estimated at $13.8
million. In addition, through September 30, 1998, Clorox has expensed
accelerated strategic upgrade costs of $9.6 million with anticipated remaining
accelerated strategic upgrade costs of $6.4 million. Clorox has spent
approximately 17% of its 1998 fiscal year information technology budget, and
expects to spend approximately 12% of its 1999 fiscal year information
technology budget, on Y2K remediation issues. Clorox has not deferred any
critical information technology projects because of its Year 2000 program
efforts, which are primarily being addressed through a dedicated team within
Clorox's information technology group. Time and cost estimates are based on
currently available information and could be affected by the ability to correct
all relevant computer codes and equipment, and the Y2K readiness of Clorox's
business partners, among other factors.
 
    Clorox has not yet performed an assessment of the impact of the merger on
its Y2K costs. However, Clorox expects that overall Y2K costs will increase
based on First Brands' own assessment of these costs. In this assessment, First
Brands reviewed the potential impact on both its information systems and on
ancillary systems. This review included, but was not limited to, an analysis of
all significant systems or assets that may use microcontrollers. First Brands is
now in the final testing phase of its sales, costing and production modules and
currently intends to implement these systems in the first and second quarters of
calendar 1999. In addition to upgrading its own systems, First Brands has
contacted certain significant suppliers to determine their Y2K readiness. To
date, First Brands has not received any information which would indicate that
the Y2K issue will result in any significant disruption from its suppliers.
However, if necessary modifications and conversions by First Brands are not made
on a timely basis, or if key third parties are not Y2K ready, Y2K problems could
have a material adverse effect on First Brands' operations. First Brands has
spent approximately $29 million from a total budget of $33 million for a
comprehensive upgrade to its computer applications, which will address a major
portion of its Y2K issues. First Brands' international subsidiaries, other than
those in Canada (which are covered in the U.S. program), have established their
own plans for addressing the Y2K issue, and have computer systems that either
are compliant as of June 30, 1998 or are expected to be compliant by December
31, 1998. The international subsidiaries performed assessments similar to those
conducted by First Brands in the U.S. and Canada. Y2K efforts of both companies
will be combined and continued following the merger. Although First Brands'
timetables may affect the target dates and contingency plans of Clorox's
original Y2K program, following the merger Clorox expects to be Y2K compliant
before the arrival of the new millennium.

EURO CONVERSION
 
    On January 1, 1999, certain countries in the European Union ("EU") that are
participating in the EU's Economic and Monetary Union ("EMU") will begin using
the "euro" as their single currency, while continuing to use their own notes and
coins (representing their equivalent in euros) for cash transactions. Banknotes
and coins denominated in euros are expected to be put into circulation in these
EMU countries during 2002. Uncertainty exists as to the effect the introduction
of the euro, including the conversion of cash in circulation into euros, will
have on the marketplace. Additionally, all of the final rules and regulations
have not yet been defined and finalized by the European Commission with regard
to the euro. Clorox is assessing the effect the euro will have on its internal
systems and sales of its products. Clorox expects to take appropriate actions
based on the results of such assessment. Clorox has not yet determined the costs
of addressing this issue. In addition, Clorox has non-controlled joint ventures
in Europe that could be affected by the euro introduction.
 
GOVERNMENT REGULATIONS
 
    The manufacture, packaging, storage, distribution and labeling of Clorox's
and First Brands' products and Clorox's and First Brands' business operations
generally are all subject to extensive federal, state, and foreign laws and
regulations. For example, in the United States, many of Clorox's and First
Brands' products are subject to regulation by the Environmental Protection
Agency, the Food and Drug Administration, and the Consumer Product Safety
Commission. Most states have agencies that regulate in parallel to these federal
agencies. The failure to comply with applicable laws and regulations in these or
other areas could subject Clorox and First Brands to civil remedies, including
fines, injunctions, recalls or seizures, as well as potential criminal
sanctions, any of which could have a material adverse effect on the combined
company. Loss of or failure to obtain necessary permits and registrations could
delay or prevent Clorox or First Brands from introducing new products, building
new facilities or acquiring new businesses and could adversely affect operating
results.
 
ENVIRONMENTAL MATTERS
 
    Clorox and First Brands are subject to various environmental laws and
regulations in the jurisdictions in which they operate, including those relating
to air emissions, water discharges, the handling and disposal of solid and
hazardous wastes, and the remediation of contamination associated with the use
and disposal of hazardous substances. Clorox and First Brands have incurred, and
will continue to incur, capital and operating expenditures and other costs in
complying with such laws and regulations in the United States and
internationally. Clorox and First Brands are currently involved in or have
potential liability with respect to the remediation of past contamination in the
operation of certain of their presently and formerly owned and leased
facilities. In addition, certain of Clorox's and First Brands' present and
former facilities have been or had been in operation for many years, and over
such time, some of these facilities may have used substances or generated and
disposed of wastes that are or may be considered hazardous. It is possible that
such sites, as well as disposal sites owned by third parties to which Clorox and
First Brands have sent waste, may in the future be identified and become the
subject of remediation. Accordingly, although each of Clorox and First Brands
believes that it is currently in substantial compliance with applicable
environmental requirements, it is possible that the combined company could
become subject to additional environmental liabilities in the future that could
result in a material adverse effect on the combined company's results of
operations or financial condition.
 
IMPORTANCE OF INTELLECTUAL PROPERTY
 
    Clorox and First Brands rely on trademark, trade secret, patent and
copyright law to protect their intellectual property. There can be no assurance
that such intellectual property rights can be successfully asserted in the
future or will not be invalidated, circumvented or challenged. In addition, laws
of certain foreign countries in which Clorox's and First Brands' products are or
may be sold do not
 
                                       17
<PAGE>
protect Clorox's and First Brands' intellectual property rights to the same
extent as the laws of the United States. The failure of the combined company to
protect its proprietary information and any successful intellectual property
challenges or infringement proceedings against the combined company could have a
material adverse effect on the combined company's business, operating results
and financial condition.
 
FORWARD-LOOKING STATEMENTS
 
    The information in this Proxy Statement/Prospectus and information we have
incorporated by reference in this Proxy Statement/Prospectus contains certain
forward-looking statements within the meaning of Section 21E of the Securities
Exchange Act of 1934, as amended (the "Exchange Act"), about Clorox, First
Brands, and their subsidiaries and affiliates. Although each of Clorox and First
Brands believes that, in making any such statements, its expectations are based
on reasonable assumptions, any such statement may be influenced by factors that
could cause actual outcomes and results to be materially different from those
projected. When used in this Proxy Statement/Prospectus, the words
"anticipates," "believes," "expects," "intends," and similar expressions as they
relate to Clorox, First Brands, their subsidiaries, their affiliates or their
respective management members are intended to identify such forward-looking
statements. These forward-looking statements are subject to numerous risks and
uncertainties. Important factors that could cause actual results to differ
materially from those in forward-looking statements, certain of which are beyond
the control of Clorox, First Brands or their subsidiaries, include: the impact
of general economic conditions in the U.S. and Canada and in other countries in
which Clorox, First Brands, or their subsidiaries or affiliates currently do
business (including Asia, Europe and Central and South America); industry
conditions, including competition and product and raw material prices;
fluctuations in exchange rates and currency values; capital expenditure
requirements; legislative or regulatory requirements, particularly concerning
environmental matters; interest rates; access to capital markets; the timing of
and value received in connection with asset divestitures; and obtaining required
approvals of debtholders. The actual results, performance or achievement by
Clorox, First Brands, their subsidiaries or affiliates could differ materially
from those expressed in, or implied by, these forward-looking statements and,
accordingly, no assurances can be given that any of the events anticipated by
the forward-looking statements will occur or transpire, or, if any of them do
so, what impact they will have on the results of operations and financial
condition of Clorox, First Brands, their subsidiaries or affiliates.

will be held at the Danbury Ballroom of the Danbury Hilton, 18 Ridgebury Road,
Danbury, Connecticut on Thursday, January 28, 1999 at 9:00 a.m., local time. At
the Special Meeting, which will also serve as a special meeting in lieu of an
annual meeting, the holders of First Brands common stock, par value $0.01 per
share (the "First Brands Common Stock"), will consider and vote upon (1) the
approval and adoption of an Agreement and Plan of Merger, dated as of October
18, 1998, by and among Clorox, Pennant, Inc., a Delaware corporation and
wholly-owned subsidiary of Clorox ("Merger Sub"), and First Brands (the "Merger
Agreement"), (2) the election of directors, to serve a term of three years (or
until consummation of the Merger, if earlier) and (3) the ratification of the
appointment by the First Brands board of directors (the "First Brands Board") of
KPMG Peat Marwick LLP as independent auditors for the fiscal year ending June
30, 1999 (or until consummation of the Merger, if earlier).
 
RECORD DATE; SOLICITATION OF PROXIES
 
    The close of business on December 21, 1998 (the "Record Date") has been
fixed as the record date for the determination of the stockholders entitled to
notice of, and to vote at, the Special Meeting. At that date, there were
39,469,418 outstanding shares of First Brands Common Stock entitled to vote at
the Special Meeting.
 
    In addition to soliciting proxies by mail, officers, directors and employees
of First Brands, without receiving any additional compensation, may solicit
proxies by telephone, fax, in person or by other means. Arrangements will also
be made with brokerage firms and other custodians, nominees and fiduciaries to
forward proxy solicitation materials to the beneficial owners of First Brands
Common Stock held of record by such persons, and First Brands will reimburse
such brokerage firms, custodians, nominees and fiduciaries for reasonable
out-of-pocket expenses incurred by them in connection therewith. First Brands
has retained Morrow & Co. Inc. to assist in the solicitation of proxies at an
estimated cost of $15,000. Clorox and First Brands will share equally all
expenses related to printing and filing this Proxy Statement/Prospectus,
including all filing fees of the Securities and Exchange Commission (the
"Commission").
 
REVOCABILITY OF PROXIES
 
    Any holder of First Brands Common Stock may revoke a proxy at any time
before it is voted, by filing with the Secretary of First Brands an instrument
revoking the proxy or by returning a duly executed proxy bearing a later date,
or by attending the Special Meeting and voting in person. Any such filing should
be made to the attention of Joseph B. Furey, Secretary, First Brands
Corporation, 83 Wooster Heights Road, Danbury, Connecticut 06813-1911.
Attendance at the Special Meeting will not by itself constitute revocation of a
proxy.
 
                    MATTERS TO BE CONSIDERED AT THE MEETING
 
APPROVAL AND ADOPTION OF THE MERGER AGREEMENT
 
    At the Special Meeting, you will be asked to approve and adopt the Merger
Agreement. Pursuant to the Merger Agreement, Merger Sub will be merged with and
into First Brands, and First Brands, as the surviving corporation (the
"Surviving Corporation"), will become a wholly-owned subsidiary of Clorox (the
"Merger"). A vote of two thirds of the outstanding shares of First Brands Common
Stock entitled to be cast at the Special Meeting is required to approve and
adopt the Merger Agreement. After careful consideration, the First Brands Board
by a unanimous vote of the directors present has determined that the Merger is
fair to and in the best interests of the stockholders of First Brands.
 
                                       19

Accordingly, the First Brands Board has approved the Merger Agreement by a
unanimous vote of the directors present.
 
    THE FIRST BRANDS BOARD RECOMMENDS A VOTE FOR THIS PROPOSAL.
 
ELECTION OF DIRECTORS
 
    The First Brands Board is divided into three classes of membership, with
terms expiring on different annual meeting dates. Three or four of the members
of the First Brands Board are elected each year to serve as directors for a term
of three years. Directors are elected for the terms specified and continue in
office until their respective successors have been elected.
 
    The First Brands Board, at its meeting held on June 5, 1998, selected the
following three nominees for election at the next annual meeting: Mr. Robert F.
Bernstock, Mr. Denis Newman and Mr. Ervin R. Shames. Each nominee shall, if
elected, serve for a three-year term expiring on the date of the annual meeting
of stockholders in the year 2001 and until their successors are elected (or upon
consummation of the Merger, if earlier).
 
    Certain information with respect to the nominees for election as director
and with respect to directors whose terms extend beyond the date of the Special
Meeting, which is being held in lieu of an annual meeting, is set forth below.
If the Merger is consummated, the directors of Merger Sub will be the initial
directors of the Surviving Corporation in the Merger.
 
    Should any one or more of the nominees be unable or unwilling to serve
(which is not expected), the proxies (except proxies marked to the contrary) may
be voted for such other person or persons as the First Brands Board may
recommend.

    THE FIRST BRANDS BOARD RECOMMENDS A VOTE FOR THIS PROPOSAL.

<PAGE>
                                   THE MERGER
 
    THIS SECTION OF THE PROXY STATEMENT/PROSPECTUS DESCRIBES CERTAIN ASPECTS OF
THE PROPOSED MERGER. TO THE EXTENT THAT IT RELATES TO THE MERGER AGREEMENT AND
THE TERMS OF THE MERGER, THE FOLLOWING DESCRIPTION IS QUALIFIED IN ITS ENTIRETY
BY REFERENCE TO THE MERGER AGREEMENT, WHICH IS ATTACHED AS APPENDIX A TO THIS
PROXY STATEMENT/PROSPECTUS AND IS INCORPORATED HEREIN BY REFERENCE. YOU ARE
URGED TO READ THE MERGER AGREEMENT.
 
    The Merger Agreement provides that the Merger will be consummated if the
approval of the First Brands stockholders is obtained and all other conditions
to the Merger are satisfied or waived as provided in the Merger Agreement. Upon
consummation of the Merger, each outstanding share of First Brands Common Stock
will be converted into the right to receive a fraction of a share of fully paid
and nonassessable Clorox common stock, par value $1.00 per share ("Clorox Common
Stock"), equal to the Exchange Ratio. Cash will be delivered in lieu of any
remaining fractional share as described in the Merger Agreement.
 
    Based upon the capitalization of Clorox and First Brands as of December 15,
1998, assuming an Exchange Ratio of 0.3545, and assuming exercise of all
outstanding First Brands options and all exercisable Clorox options, the
stockholders of First Brands will own approximately 12.2% of the outstanding
Clorox Common Stock following consummation of the Merger. Such percentage could
change depending on whether and to what extent shares of Clorox Common Stock and
First Brands Common Stock are issued upon exercise of outstanding Clorox or
First Brands stock options or warrants, on the price of Clorox Common Stock
(which, in some cases, will determine the Exchange Ratio) (see "--Merger
Consideration" below) and on whether Clorox needs to issue additional shares of
common stock to third parties in connection with pooling of interests accounting
treatment for the Merger.
 
BACKGROUND OF THE MERGER
 
    On or about April 16, 1998, a senior executive of a large publicly held
corporation (the "Other Bidder") contacted, without having been solicited to do
so, Mr. William V. Stephenson, Chairman and Chief Executive Officer of First
Brands, and expressed interest in acquiring First Brands and proposed setting up
a meeting between the two companies to discuss the matter further. Senior
executives from each of First Brands and the Other Bidder met on or about May 6
to discuss the broad outline of a proposed acquisition. Thereafter, in early
May, the Other Bidder orally presented a preliminary indication of interest to
acquire First Brands for cash, for an amount within a stated range of values,
conditioned upon it being given the opportunity to perform extensive due
diligence upon First Brands. During this period, First Brands requested Lehman
Brothers to advise it on financial issues relating to any potential acquisition
of First Brands.
 
    The First Brands Board held a telephonic meeting on May 15, 1998 at which it
voted unanimously to reject the Other Bidder's preliminary indication of
interest as inadequate. Lehman Brothers prepared a preliminary review of
alternatives and valuation of First Brands, which it presented to the First
Brands Board on June 19, 1998. The Board discussed at length the valuation
prepared by Lehman Brothers as well as First Brands' financial position,
strategic alternatives, business plans and prospects. The First Brands Board
authorized management to provide some limited non-public financial and operating
information to the Other Bidder, subject to appropriate provisions for
confidentiality, in an effort to determine if the Other Bidder would increase
its offer sufficiently to warrant further negotiations.
 
    Following additional intermittent discussions between First Brands and the
Other Bidder during June and July 1998, First Brands and the Other Bidder signed
a confidentiality agreement on July 14, 1998, after which First Brands furnished
to the Other Bidder certain financial and operating data. Following its review
of such information, on August 20, 1998 the Other Bidder proposed, subject to
certain conditions, that it purchase First Brands for $32 per share in cash.
 
                                       23
<PAGE>
    During the week of July 20, 1998, Mr. G. Craig Sullivan, Chairman and Chief
Executive Officer of Clorox, called, without having been solicited to do so, Mr.
Alfred E. Dudley, formerly Chairman, and currently Chairman of the Executive
Committee, of First Brands, and requested a meeting. On July 30, 1998, Mr.
Sullivan met with Mr. Dudley and indicated to Mr. Dudley Clorox's interest in
discussing a possible acquisition of First Brands. On July 31, Mr. Dudley and
Mr. Stephenson discussed this overture, and at a meeting on August 5, they
discussed the overture with members of the First Brands Board and Lehman
Brothers. On August 5, the First Brands Board authorized management to provide
similar information to Clorox as had been provided to the Other Bidder, subject
to appropriate provisions for confidentiality. On August 10, 1998, Clorox and
First Brands signed a confidentiality agreement, after which First Brands
furnished to Clorox the same type of due diligence information it had provided
to the Other Bidder. On August 30, Clorox provided an oral indication of
interest to acquire the stock of First Brands in a stock-for-stock exchange
which would value the stock of First Brands in the range of $29 to $32 per
share. Clorox requested that it be provided with additional due diligence
material to enable it to refine its offer.
 
    The First Brands Executive Committee had a telephonic meeting on September
1, 1998 to discuss what action, if any, to take with regard to the indications
of interest from each of Clorox and the Other Bidder. In light of the sharp
decline in the equity markets in August, the Committee requested that Lehman
Brothers update its preliminary valuation of First Brands based on current
market conditions for review by the First Brands Board.
 
    The First Brands Board met on September 4, 1998 to discuss the two
indications of interest. At the meeting, Lehman Brothers presented a detailed
and updated analysis of the factors affecting a valuation of First Brands, an
analysis of both proposals and recommendations of measures First Brands might
consider taking to enhance its value and prospects. The First Brands Board
discussed (i) First Brands' earnings prospects, (ii) the relative value to First
Brands' stockholders of a tax-free stock transaction that could be accounted for
as a pooling of interests compared to an all cash transaction that would be
taxable to stockholders and accounted for using the purchase method, (iii)
Clorox's business portfolio and historical stock performance and future
prospects, (iv) First Brands' spending levels for infrastructure improvements
and research and development, (v) whether First Brands had sufficient scale to
compete as an independent company over the near and medium term and (vi) whether
First Brands had the financial flexibility to expand via additional acquisitions
while maintaining a desirable credit rating.
 
    The First Brands Board agreed with management's recommendation that First
Brands advise each of Clorox and the Other Bidder that their respective
indications of interest were at too low a price level, but that First Brands
would be willing to provide each of such parties with additional due diligence
material, including the ability to conduct site visits, to enable each of the
parties to justify a meaningful increase in their respective indications of
interest. Subsequent to this meeting, First Brands informed each of Clorox and
the Other Bidder that the Board considered their proposals to be below the range
of fair valuation and that the Board would not consider a proposal in the $32
per share range.
 
    During September and October 1998, each of Clorox and the Other Bidder
conducted further due diligence, including visits to First Brands manufacturing
locations as well as reviews of First Brands' research and development.
 
    On October 1 and October 2, 1998, Lehman Brothers met with the financial
advisors of each of Clorox and the Other Bidder in order to provide its
perspective on value and process and to encourage each of Clorox and the Other
Bidder to provide their best offer.
 
    On October 2, 1998, the Other Bidder delivered a letter to First Brands in
which it reiterated its offer to acquire all of the outstanding shares of First
Brands for $32 per share in cash, with such offer being contingent on matters
such as the completion of confirmatory due diligence. As an alternative,
 
                                       24
<PAGE>
the Other Bidder indicated its willingness to more narrowly limit the number of
matters on which its offer was contingent if its purchase price was reduced to
$31.50 per First Brands share.
 
    On October 8, 1998, Clorox delivered a letter to First Brands confirming its
willingness to exchange Clorox shares for First Brands shares in a tax-free
stock-for-stock merger to be accounted for as a pooling of interests. This
proposal valued First Brands at $35.50 per share based on a fixed exchange ratio
and was conditioned upon the completion of confirmatory due diligence. The
proposal did not contain any collar or other form of price protection in the
event of fluctuations in the value of Clorox shares prior to closing.
 
    The First Brands Board had a telephonic meeting on October 9, 1998 to
discuss the current offers from Clorox and the Other Bidder. Lehman Brothers
indicated that Clorox's revised bid fell within its valuation range for First
Brands shares. The Board viewed Clorox's revised proposal to be attractive
inasmuch as such proposal fell within Lehman Brothers' valuation range and would
allow the stockholders of First Brands to participate in the equity of a company
with an excellent track record; however, the Board noted that because Clorox's
proposal was based on a fixed exchange ratio, without any collar or other form
of price protection, the consideration which would actually be received by the
First Brands stockholders at the time of closing could be lower than $35.50 per
share.
 
    The First Brands Board determined that it was critical that the terms of any
proposal protect the value to be received by the First Brands stockholders,
especially in light of the volatility which was being experienced in the equity
markets. The First Brands Board authorized Lehman Brothers and Skadden, Arps,
Slate, Meagher & Flom LLP ("Skadden"), First Brands' corporate counsel, to
conduct further discussions with Clorox, negotiate the terms of a contract with
Clorox, and bring such contract back to the First Brands Board for its
consideration. The First Brands Board indicated to Lehman Brothers and Skadden
that they should request that the contract include a provision under which First
Brands stockholders would receive $35.50 in value of Clorox shares at the
closing regardless of the price at which Clorox shares were trading at such time
(a so-called "fixed price mechanism").
 
    Subsequent to the October 9th Board meeting, Lehman Brothers informed the
Other Bidder that First Brands was not interested in pursuing discussions on its
proposal since its offer was not within Lehman Brothers' valuation range. In
addition, First Brands told Clorox that it was interested in pursuing a
strategic merger with Clorox that valued the First Brands shares at $35.50 per
share, provided the merger agreement contained a fixed price mechanism. During
the period from October 10 to October 14, First Brands and Clorox began
negotiating the terms of a merger agreement, Clorox continued conducting due
diligence upon First Brands, and First Brands conducted due diligence upon
Clorox.
 
    On Thursday morning, October 15, 1998, the Other Bidder telephoned Mr.
Stephenson, expressed strong interest in First Brands and inquired as to what
would be required in order for First Brands to support its proposal. Mr.
Stephenson advised the Other Bidder only that the price it had previously
offered was not within the range of value as determined by Lehman Brothers.
 
    Later on Thursday, Clorox provided Lehman Brothers with clarification of the
financial terms of its proposal, and indicated its willingness to provide a
fixed price mechanism resulting in consideration of $35.50 per First Brands
share so long as Clorox's stock price was above $89 per share. Under such
proposal, if the per share price of Clorox Common Stock fell below $89, First
Brands stockholders would receive 0.3989 of a Clorox share (that is, $35.50
divided by $89). First Brands' management continued to view the proposal as
having too much risk for its stockholders.
 
    On Thursday afternoon, the Other Bidder increased its offer to $35 or $35.50
per First Brands share, depending on the number of matters upon which the offer
would be contingent. The Other Bidder expressed its willingness to provide such
consideration either in cash or, in the alternative, in stock pursuant to a
tax-free exchange which would not be accounted for as a pooling of interests.
Such
 
                                       25
<PAGE>
offer continued to be subject to confirmatory due diligence, and the Other
Bidder indicated that it could be prepared to sign a definitive agreement by
Tuesday, October 20th.
 
    On Friday, October 16, following a meeting of the Clorox board of directors
(the "Clorox Board"), Clorox increased its offer for First Brands to $37.50 per
share with a collar that would result in a fixed price being paid to the First
Brands stockholders so long as Clorox shares traded within a range of $80 to
$120. Clorox indicated that it was prepared to sign a definitive agreement over
the weekend and would like to announce the merger the following Monday.
 
    Later on Friday, the First Brands Board had a telephonic meeting at which
Lehman Brothers provided an analysis of the latest Clorox offer. The First
Brands Board considered the fact that while the Other Bidder's offer, which
contemplated the Other Bidder promptly commencing a cash tender offer for First
Brands shares, could be completed in 25-30 days, Clorox's offer provided for a
stock-for-stock merger, which would probably take approximately four months to
complete. On the other hand, while the merger agreement with Clorox was almost
fully negotiated, much contract negotiation was still required to be done with
the Other Bidder, and certain due diligence issues still remained outstanding
with the Other Bidder. Acknowledging that the Other Bidder might still raise its
offer, the First Brands Board voted unanimously to instruct Lehman Brothers to
advise the financial advisor to the Other Bidder that it should make its best
and highest offer, but no lower than $37.50 per share in cash, prior to noon on
Saturday, October 17th, accept the terms of the contract First Brands had
already negotiated with Clorox (with such modifications as would be necessary to
take account of the differing transaction structures) and drop all further due
diligence matters. Subsequent to the First Brands Board meeting, Lehman Brothers
so advised the Other Bidder's financial advisor.
 
    At shortly before noon on Saturday, October 17th, the Other Bidder's
financial advisor informed Lehman Brothers that the Other Bidder had agreed to
increase its offer to $37.50 per share in cash, eliminate nearly all additional
due diligence requirements and was prepared to sign an agreement on Sunday,
October 18th.
 
    The First Brands Board had a telephonic board meeting on October 17, 1998 at
which it considered the potential for a further bid from Clorox and the merits
of an all cash tender offer compared to a stock-for-stock merger at a fixed
price ratio (within a particular band). Following the discussion, the First
Brands Board agreed to reject Clorox's offer of $37.50 per share due to price
risk and timing concerns. The First Brands Board agreed to reconvene
telephonically on Sunday, October 18th, at 10:00 a.m., at which time Lehman
Brothers would render its opinion based on the review of its fairness opinion
committee and the First Brands Board would resolve to finalize a transaction
with the Other Bidder.
 
    Subsequent to the October 17th Board meeting, Clorox was advised that the
First Brands Board had declined its offer due to price risk and timing issues.
 
    Late on Saturday, Clorox advised First Brands that it was increasing its bid
to $38.50 per First Brands share, subject to the same $80/$120 collar.
 
    Later on Saturday and again on Sunday morning, Lehman Brothers informed the
Other Bidder's financial advisor that it had received a higher bid from (without
naming it) Clorox, and that, as a result, it was not clear which bid the First
Brands Board would accept. In reply to Lehman Brothers' query whether the Other
Bidder wished to further revise its offer, the Other Bidder's financial advisor
was not forthcoming. Lehman Brothers then contacted Clorox's financial advisor
to confirm Clorox's offer and inquire if Clorox's offer could be revised to
provide any additional upside potential for First Brands' stockholders. Clorox's
financial advisor replied that Clorox was willing to modify the collar provision
from $80/$120 to $80/$115 (thereby permitting the First Brands stockholders to
benefit from any increase in the Clorox share price above $115 during the
pricing period) but that Clorox was unlikely to increase its $38.50 per share
offer.

<PAGE>
    On Sunday, October 18, the First Brands Board convened telephonically.
During the meeting, the Board was informed that Clorox had increased its offer
to $39 per share with an $80/$115 collar. The Board conducted a full and
complete discussion of both Clorox's and the Other Bidder's last best offers,
the risks and upside potential of the proposed Clorox $80/$115 collar, the
impact on First Brands' employees of accepting either offer, the relative merits
of the $37.50 cash offer and the $39 stock-for-stock merger, Commission pooling
issues, Clorox's historical and projected financial and stock performance, the
likely impact of the proposed transaction on Clorox's earnings per share and
management's recommendation to accept the Clorox offer. Following discussion,
and after reviewing with Lehman Brothers its valuation analysis of First Brands
and receiving from Lehman Brothers its oral opinion (later confirmed in writing)
that the Exchange Ratio to be offered by Clorox was fair to the First Brands
stockholders from a financial point of view, the Board resolved to accept the
Clorox proposal. Later on Sunday, Clorox, Merger Sub and First Brands executed
the Merger Agreement.
 
    On Monday, October 19, Clorox and First Brands issued a joint press release
announcing the execution of the Merger Agreement.
 
REASONS FOR THE MERGER; RECOMMENDATIONS OF THE FIRST BRANDS BOARD
 
    At its meeting on October 18, 1998, the First Brands Board (with one
director absent) unanimously determined that (a) the terms of the Merger
Agreement and the transactions contemplated thereby are advisable and fair to
and in the best interests of First Brands and its stockholders, (b) directed
that the proposed transaction be submitted for consideration by the First Brands
stockholders and (c) recommended that the First Brands stockholders vote for
approval and adoption of the Merger, the Merger Agreement and the transactions
contemplated thereby. In reaching this conclusion, the First Brands Board, with
the assistance of its financial and legal advisors, considered and analyzed a
number of factors, including, without limitation, the following:
 
        (i) That based on information with respect to the financial condition,
    results of operations, cash flow, business and prospects of First Brands on
    both a stand-alone basis and as compared with those available in combination
    with Clorox, the First Brands stockholders would benefit substantially from
    a business combination with Clorox. Such benefits would consist of the
    ability of the First Brands stockholders to continue to own an interest in
    the combined company and thereby benefit from the enhanced prospects of the
    combined company in terms of enhanced financial and operational resources
    and flexibility, the combination of complementary skills and experience of
    the two companies, as well as the combined company's enhanced ability to
    take advantage of future strategic opportunities.
 
        (ii) That the Merger should allow the combined company to meet the
    challenges of the increasingly competitive environment in the household
    products industry more effectively than First Brands could on its own.
 
       (iii) The oral presentations of Lehman Brothers and its oral opinion
    (later confirmed in writing) that the Merger consideration was fair from a
    financial point of view to the holders of First Brands Common Stock. See
    "--Opinion of Lehman Brothers" for a discussion of Lehman Brothers' opinion.
    A copy of this opinion, which is subject to certain limitations,
    qualifications and assumptions as stated therein, is included as Appendix B
    hereto and should be read carefully and in its entirety.
 
        (iv) That the terms of the Clorox proposal were more favorable to the
    First Brands stockholders than the terms of the proposal of the Other
    Bidder.
 
        (v) That the Merger consideration remains fixed at a value of $39 per
    share so long as shares of Clorox Common Stock are trading at greater than
    $80 and less than or equal to $115 during a specified period prior to
    closing; that First Brands' stockholders will have the opportunity to
    participate in the appreciation of the price of Clorox Common Stock if the
    price of such stock
 
                                       27
<PAGE>
    surpasses $115 per share during such specified period of time prior to
    closing; and that First Brands stockholders will receive less than $39 per
    share only under the circumstance where Clorox Common Stock falls below $80
    per share during such specified period of time prior to closing.
 
        (vi) The terms of the Merger Agreement, the consideration to be received
    by the First Brands stockholders in the Merger and the fact that the receipt
    of Clorox Common Stock by the First Brands stockholders upon consummation of
    the Merger will be a tax-free exchange (other than taxes payable on cash
    received for fractional shares).
 
       (vii) The historical market prices for shares of First Brands Common
    Stock, and historical price to earnings trading multiples for such shares.
 
      (viii) The historical market prices for shares of Clorox Common Stock, and
    historical price to earnings trading multiples for such shares.
 
        (ix) The prices, multiples of revenues and earnings measures and premium
    over market value paid in recent acquisitions of other companies, including
    manufacturers of consumer products.
 
        (x) The impact of each of the Clorox proposal and the proposal of the
    Other Bidder on First Brands' employees.
 
    We do not intend the foregoing discussion of the information and factors
that were given weight by the First Brands Board to be exhaustive, but we
believe it includes all material factors considered by the First Brands Board.
In view of the variety of factors considered in connection with its evaluation
of the proposed Merger and the terms of the Merger Agreement, the First Brands
Board did not deem it practicable to, and did not, quantify or otherwise assign
relative weights to the specific factors considered in reaching its conclusion,
and individual directors may have given different weights to different factors.
After considering all such factors, at a telephonic meeting held on October 18,
1998, the First Brands Board (with one director absent) unanimously approved the
Merger, the Merger Agreement and the transactions contemplated thereby as fair
to, and in the best interests of, First Brands and its stockholders.
 
    THE FIRST BRANDS BOARD UNANIMOUSLY RECOMMENDS TO ITS STOCKHOLDERS THAT THEY
VOTE "FOR" APPROVAL AND ADOPTION OF THE MERGER AGREEMENT.
 
    In considering the recommendation of the First Brands Board with respect to
approving the Merger Agreement and the transactions contemplated thereby, First
Brands stockholders should be aware that certain officers and directors of First
Brands have certain interests in the proposed Merger that are different from and
in addition to the interests of First Brands stockholders generally. The First
Brands Board was aware of these interests and considered them in approving the
Merger and the Merger Agreement. See "--Interests of Certain Persons in the
Merger."
 
OPINION OF LEHMAN BROTHERS
 
    Lehman Brothers has acted as financial advisor to First Brands in connection
with the Merger. As part of its role as financial advisor to First Brands,
Lehman Brothers, on October 18, 1998, delivered an oral opinion (confirmed in
writing in an opinion dated the same date) (the "Lehman Brothers Opinion") to
the effect that, as of such date, the Exchange Ratio to be offered to the First
Brands stockholders in the Merger was fair, from a financial point of view, to
such stockholders.
 
    A copy of the Lehman Brothers Opinion is included at the back of this Proxy
Statement/Prospectus as Appendix B. Holders of First Brands Common Stock should
read the Lehman Brothers Opinion in its entirety for a discussion of the
assumptions made, matters considered and limitations on the review undertaken by
Lehman Brothers in rendering its opinion. The summary of the Lehman Brothers
Opinion set forth in this Proxy Statement/Prospectus is qualified in its
entirety by reference to the full text of the Lehman Brothers Opinion.
 
                                       28
<PAGE>
    No limitations were imposed by First Brands on the scope of Lehman Brothers'
investigation or the procedures to be followed by Lehman Brothers in rendering
its opinion, except that (i) Lehman Brothers was not provided with and did not
have access to any financial forecasts or projections prepared by the management
of Clorox as to the future financial performance of Clorox and (ii) Lehman
Brothers was not authorized to solicit, and did not solicit, any indications of
interest from any third party with respect to a purchase of all or a part of
First Brands' businesses. Lehman Brothers was not requested to and did not make
any recommendation to the First Brands Board as to the form or amount of
consideration to be received by First Brands' stockholders in the Merger, which
was determined through arm's-length negotiations between First Brands and Clorox
and their respective advisors. In arriving at its opinion, Lehman Brothers did
not ascribe a specific range of value to First Brands, but made its
determination as to fairness, from a financial point of view, to First Brands'
stockholders of the Exchange Ratio to be offered to such stockholders in the
Merger on the basis of the financial and comparative analyses described below.
The Lehman Brothers Opinion is for the use and benefit of the First Brands Board
and was rendered to the First Brands Board in connection with its consideration
of the Merger. The Lehman Brothers Opinion is not intended to be and does not
constitute a recommendation to any stockholder of First Brands as to how such
stockholder should vote with respect to the Merger. Lehman Brothers was not
requested to opine as to, and its opinion does not in any manner address, First
Brands' underlying business decision to proceed with or effect the Merger.
 
    In arriving at its opinion, Lehman Brothers reviewed and analyzed:
 
    - the Merger Agreement and the specific terms of the Merger,
 
    - such publicly available information concerning First Brands and Clorox
      that Lehman Brothers believed to be relevant to its analysis, including
      the Annual Reports on Form 10-K for the fiscal years ended June 30, 1997
      and June 30, 1998,
 
    - financial and operating information with respect to the business,
      operations and prospects of First Brands furnished to them by First
      Brands,
 
    - financial and operating information with respect to the business and
      operations of Clorox furnished to them by Clorox,
 
    - the trading history of First Brands Common Stock from October 15, 1993 to
      the date of the Lehman Brothers Opinion and a comparison of that trading
      history with those of other companies that Lehman Brothers deemed
      relevant,
 
    - the trading history of Clorox Common Stock from October 15, 1993 to the
      date of the Lehman Brothers Opinion and a comparison of that trading
      history with those of other companies that Lehman Brothers deemed
      relevant,
 
    - a comparison of the historical financial results and present financial
      condition of First Brands with those of other companies that Lehman
      Brothers deemed relevant,
 
    - a comparison of the historical financial results and present financial
      condition of Clorox with those of other companies that Lehman Brothers
      deemed relevant,
 
    - a comparison of the financial terms of the Merger with the financial terms
      of certain other transactions that Lehman Brothers deemed relevant,
 
    - the pro forma impact of the Merger on Clorox,
 
    - estimates of third party research analysts with respect to the future
      financial performance of First Brands and Clorox and
 
    - an indication of interest received by First Brands from the Other Bidder
      with respect to an acquisition of First Brands. In addition, Lehman
      Brothers had discussions with the management of each of First Brands and
      Clorox concerning their respective businesses, operations, assets,
 
                                       29
<PAGE>
      financial conditions and prospects and with the management of First Brands
      concerning the cost savings and other strategic benefits expected by them
      to result from a combination of the businesses of First Brands and Clorox,
      and undertook such other studies, analyses and investigations as Lehman
      Brothers deemed appropriate.
 
    In arriving at its opinion, Lehman Brothers assumed and relied upon the
accuracy and completeness of the financial and other information used by it
without assuming any responsibility for independent verification of such
information and further relied upon the assurances of management of each of
First Brands and Clorox that they were not aware of any facts or circumstances
that would make such information inaccurate or misleading. With respect to the
financial projections of First Brands for fiscal year 1999, upon advice of First
Brands, Lehman Brothers assumed that such projections were reasonably prepared
on a basis reflecting the then best currently available estimates and judgments
of the management of First Brands as to the future financial performance of
First Brands and that First Brands would perform substantially in accordance
with such projections. In addition, for purposes of its analysis, Lehman
Brothers also extrapolated the financial trends of the latest three fiscal years
and the First Brands' projections for fiscal year 1999 to develop financial
projections for First Brands for the fiscal years 2000 through 2003, and then
considered certain more conservative assumptions and estimates which resulted in
certain adjustments to such projections. Lehman Brothers discussed the
extrapolation process, the resulting projections and the adjusted projections
with the management of First Brands and they agreed with the appropriateness of
the extrapolation process and the use of the resulting projections and the
adjusted projections in performing Lehman Brothers' analysis. In arriving at its
opinion, Lehman Brothers was not provided with, and did not have access to, any
financial projections prepared by the management of Clorox. Accordingly, with
respect to the future financial performance of Clorox on a stand-alone basis,
upon advice of Clorox, Lehman Brothers assumed that the published estimates of
third party research analysts were a reasonable basis upon which to evaluate the
future financial performance of Clorox on a stand-alone basis and that Clorox
would perform, on a stand-alone basis, substantially in accordance with those
estimates. In arriving at its opinion, Lehman Brothers did not conduct a
physical inspection of the properties and facilities of First Brands and did not
make or obtain any evaluations or appraisals of the assets or liabilities of
First Brands. In addition, Lehman Brothers was not authorized to solicit, and
Lehman Brothers did not solicit, any indications of interest from any third
party with respect to the purchase of all or a part of First Brands' businesses.
Upon the advice of First Brands and Clorox, Lehman Brothers assumed that the
Merger will qualify for pooling-of-interests accounting treatment, and upon the
advice of First Brands, Clorox and their respective legal advisors, Lehman
Brothers assumed that the Merger will qualify as a reorganization within the
meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended (the
"Code"), and therefore as a tax-free transaction to the stockholders of First
Brands. The Lehman Brothers Opinion was necessarily based upon market, economic
and other conditions as they existed on, and could be evaluated as of, the date
of such opinion.
 
    In connection with preparing its presentation to the First Brands Board on
October 18, 1998, and its written opinion dated October 18, 1998, Lehman
Brothers performed a variety of financial and comparative analyses as described
below. The preparation of a fairness opinion involves various determinations as
to the most appropriate and relevant methods of financial and comparative
analysis and the application of those methods to the particular circumstances
and, therefore, such an opinion is not readily susceptible to summary
description. Furthermore, in arriving at its opinion, Lehman Brothers did not
attribute any particular weight to any analysis or factor considered by it, but
rather made qualitative judgments as to the significance and relevance of each
analysis and factor. Accordingly, Lehman Brothers believes that its analyses
must be considered as a whole and that considering any portions of such analyses
and factors, without considering all analyses and factors, could create a
misleading or incomplete view of the process underlying its opinion. In its
analyses, Lehman Brothers made numerous assumptions with respect to industry
performance, general business and economic conditions and other matters, many of
which are beyond the control of First Brands and Clorox. None
 
                                       30
<PAGE>
of First Brands, Clorox, Lehman Brothers or any other person assumes
responsibility if future results are materially different from those discussed.
Any estimates contained in these analyses are not necessarily indicative of
actual values or predictive of future results or values, which may be
significantly more or less favorable than as set forth therein. In addition,
analyses relating to the value of businesses do not purport to be appraisals or
to reflect the prices at which businesses actually may be sold.
 
    TRANSACTION TERMS.  Upon the effectiveness of the Merger, and so long as the
Clorox Average Share Price is greater than $80 and less than or equal to $115
per share, holders of First Brands Common Stock will receive sufficient shares
of Clorox Common Stock to provide a value of $39 for each share of First Brands
Common Stock (the "Fixed Price Ratio"). If the Clorox Average Share Price is $80
or less, each share of First Brands Common Stock will be converted into 0.4875
of a share of Clorox Common Stock (the "Ratio Cap"). If the Clorox Average Share
Price is greater than $115, each share of First Brands Common Stock will be
converted into 0.3391 of a share of Clorox Common Stock (the "Ratio Floor," and
together with the Ratio Cap and the Fixed Price Ratio, the "Exchange Ratio").
 
    STOCK TRADING HISTORY.  Lehman Brothers considered historical data
concerning the history of the trading prices for First Brands Common Stock and
Clorox Common Stock for the period from October 15, 1993 to October 16, 1998
(the last trading date prior to the delivery of the Lehman Brothers Opinion) and
the relative stock price performances during this same period of First Brands,
Clorox and the Standard & Poors 400 Index and the Standard & Poors Consumer
Staples Index. During this period, the closing stock price of First Brands
ranged from $15.19 to $29.25 per share, and the closing stock price of Clorox
ranged from $23.56 to $109.94 per share. During the one-year period prior to the
announcement of the Merger, the closing stock price of First Brands ranged from
$19.63 to $28.13 per share, and the closing stock price of Clorox ranged from
$66.94 to $109.94 per share. In addition, Lehman Brothers noted that First
Brands Common Stock had its all-time high of $29.25 on March 26, 1996. Lehman
Brothers noted that over both the one-year and the five-year periods, Clorox had
outperformed the two indexes while First Brands had not kept pace with the
indexes.
 
    COMPARABLE COMPANY ANALYSIS.  Lehman Brothers reviewed the public stock
market trading multiples for selected companies that Lehman Brothers deemed
comparable to First Brands, including (in order by market capitalization,
largest to smallest) The Procter & Gamble Company, Unilever plc, Sara Lee
Corporation, Kimberly-Clark Corporation, Colgate-Palmolive Company, Clorox,
Ralston-Purina Company, Newell Company, Rubbermaid Incorporated, The Dial
Corporation, RPM, Incorporated, Lancaster Colony, Church & Dwight Company,
Incorporated, WD-40 Company and Oil Dri Corporation of America (collectively,
the "Comparable Companies"). Using publicly available information, Lehman
Brothers calculated and analyzed the common equity market value multiples of
historical and projected net income and enterprise value multiples of certain
historical financial criteria (such as revenue, earnings before interest, taxes,
depreciation and amortization ("EBITDA"), and earnings before interest and taxes
("EBIT")) for each of the Comparable Companies. The enterprise value of each
company was obtained by adding its short and long-term debt to the sum of the
market value of its common equity, the value of its preferred stock (at
liquidation value) and the book value of any minority interest, and subtracting
its cash and cash equivalents. As of October 16, 1998, the last trading date
prior to the delivery of the Lehman Brothers Opinion, the Comparable Companies'
median enterprise multiples of actual or, where necessary, estimated pro forma,
latest twelve months ("LTM") EBITDA, LTM EBIT and LTM Revenues were 12.4x, 15.2x
and 1.81x, respectively. In addition, as of October 16, 1998, the Comparable
Companies' median multiple of the current stock price to (i) the latest twelve
months earnings per share (the "LTM P/E Multiple"), (ii) the estimated 1998
earnings per share (the "1998 P/E Multiple"), based on data from First Call and
I/B/E/S International, Inc. ("IBES"), service companies used widely by the
investment community to gather earnings estimates from various research analysts
and (iii) the estimated 1999 earnings per share (the "1999 P/E Multiple"), also
based on First Call and IBES data, were 24.3x, 22.6x and 19.7x, respectively.
Lehman
 
                                       31
<PAGE>
Brothers calculated the implied equity values per share of First Brands Common
Stock for the median LTM P/E Multiple, 1998 P/E Multiple, 1999 P/E Multiple, LTM
EBITDA enterprise multiple, LTM EBIT enterprise multiple and LTM Revenue
enterprise multiple which yielded implied equity values per share of First
Brands Common Stock of $31.44, $32.73, $34.63, $40.39, $33.85 and $41.46,
respectively. Lehman Brothers noted that the $39 per share offered in the Merger
was near the upper end of the per share value range indicated above.
 
    However, because of the inherent differences between the businesses,
operations and prospects of First Brands and the business, operations and
prospects of the companies included in the Comparable Companies, Lehman Brothers
believed that it was inappropriate to, and therefore did not, rely solely on the
quantitative results of the comparable company analysis and, accordingly, also
made qualitative judgments concerning differences between the financial and
operating characteristics and prospects of First Brands and the companies
included in the Comparable Companies that would affect the public trading values
of each.
 
    COMPARABLE TRANSACTION ANALYSIS AND TRANSACTION PREMIUM ANALYSIS.  Using
publicly available information, Lehman Brothers compared selected financial data
for First Brands to similar data for selected transactions in the consumer
products industry (the "Comparable Transactions"). The Comparable Transactions
included the following: The Estee Lauder Companies Incorporated's purchase of
Aveda Corporation; Johnson (S.C.) & Son Incorporated's purchase of Dow Brands
Inc.; Tyco International Limited's purchase of Inbrand Corporation; Newell
Company's purchase of Rubbermaid Incorporated-Office Products Division; The
Procter & Gamble Company's purchase of Tambrands Incorporated; First Brands'
purchase of NationalPak from National Foods Limited; The Sherwin-Williams
Company's purchase of Thompson Minwax Holding Corp. from Forstmann Little & Co.;
Davis Companies' unsuccessful bid to acquire Carter-Wallace Incorporated; Henkel
KgaA's purchase of Loctite Corporation; The Procter & Gamble Company's purchase
of Kimberly-Clark Corporation's Scott Paper baby wipe business; JW Childs
Associates LP's purchase of Reckitt & Colman NA-Personal Products Division;
Unilever NV's purchase of Helene Curtis Industries, Inc.; Honeywell
Incorporated's purchase of Duracraft Corporation; L'Oreal S.A. (Gesparal)'s
purchase of Maybelline, Incorporated; Alberto-Culver Company's purchase of St.
Ives Laboratories, Inc.; Tenneco Incorporated's purchase of Mobil
Corporation-Plastics Division (includes Hefty Bags); The Scotts Company's
purchase of Miracle-Gro Products, Inc.; Ralston-Purina Company's purchase of
Golden Cat Corp.; Haas Wheat & Harrison Incorporated's purchase of Playtex
Products, Incorporated; Colgate-Palmolive Company's purchase of American Home
Products Corporation-Kolynos Business; Mark IV Industries, Incorporated's
purchase of Purolator Products Inc.; Reckitt & Colman's purchase of L&F
Products; Johnson & Johnson's purchase of Neutrogena Corporation; RPM,
Incorporated's purchase of Rust-Oleum Corporation; Health o meter, Inc.'s
purchase of Mr. Coffee, Inc.; and Johnson (S.C.) & Son Incorporated's purchase
of The Drackett Company from Bristol-Myers Squibb Company. Lehman Brothers
reviewed the prices paid in the Comparable Transactions in terms of the multiple
of the Transaction Enterprise Value (defined as the total consideration paid
including total debt assumed less cash and cash equivalents transferred to the
acquiror) to the (i) last twelve months revenue (the "LTM Revenue Multiple"),
(ii) last twelve months earnings before interest and tax (the "LTM EBIT
Multiple") and (iii) last twelve months earnings before interest, tax,
depreciation and amortization (the "LTM EBITDA Multiple"). Lehman Brothers noted
that (i) the LTM Revenue Multiple associated with the Merger was 1.72x as
compared to 1.66x for the median of the Comparable Transactions, (ii) the LTM
EBIT Multiple associated with the Merger was 17.0x as compared to 14.4x for the
median of the Comparable Transactions and (iii) the LTM EBITDA Multiple
associated with the Merger was 12.1x as compared to 11.5x for the median of the
Comparable Transactions.
 
                                       32
<PAGE>
    In addition, Lehman Brothers reviewed the premium paid in selected
acquisitions in the consumer products sector (the "Consumer Product
Transactions") and the premium paid in all transactions announced from January
1, 1996 to October 16, 1998 with transaction values from $1 billion to $5
billion (the "Other Transactions"). Lehman Brothers calculated the premium per
share paid by the acquiror compared to the share price of the target company
prevailing (i) one month (the "One Month Premium"), (ii) one week (the "One Week
Premium"), and (iii) one day (the "One Day Premium"), prior to the announcement
of the transaction. Lehman Brothers noted that (i) the One Month Premium
associated with the Merger was 96.9% versus 51.2% for the median of the Consumer
Product Transactions and 35.7% for the median of the Other Transactions, (ii)
the One Week Premium associated with the Merger was 92.6% versus 34.3% for the
median of the Consumer Product Transactions and 31.4% for the median of the
Other Transactions and (iii) the One Day Premium associated with the Merger was
65.0% versus 22.6% for the median of the Consumer Product Transactions and 26.2%
for the median of the Other Transactions.
 
    However, because the reasons for and the circumstances surrounding each of
the Comparable Transactions, the Consumer Product Transactions and Other
Transactions were specific to each such transaction, and because of the inherent
differences among the businesses, operations and prospects of First Brands and
the selected acquired companies analyzed, Lehman Brothers believed that it was
inappropriate to, and therefore did not, rely solely on the quantitative results
of the comparable transactions analysis and, accordingly, also made qualitative
judgments concerning the difference between the terms and characteristics of
these transactions and the Merger that would affect the acquisition values of
First Brands and such acquired companies.
 
    DISCOUNTED CASH FLOW ANALYSIS.  Lehman Brothers prepared a discounted
after-tax cash flow model that was based upon the financial projections of First
Brands as described above. Lehman Brothers used after-tax discount rates of 10%
to 12% and a terminal value based on a range of multiples of estimated EBITDA in
2003 of 10.0x to 12.0x. Based on these discount rates and the midpoint of the
terminal values, Lehman Brothers calculated the implied equity value per share
of First Brands Common Stock at $36.99 to $41.07 using the extrapolated but
unadjusted projections and $29.28 to $32.67 using the extrapolated and adjusted
projections. Lehman Brothers also performed analyses of the financial
projections using after-tax unlevered cash flow perpetuity growth rates of 4.0%
to 5.0% to determine the terminal value. These analyses resulted in implied
equity values per share of First Brands Common Stock of $31.11 to $37.82 using
the extrapolated but unadjusted projections and a 10% discount rate, and $24.18
to $29.64 using the extrapolated and adjusted projections and a 10% discount
rate.
 
    LEVERAGED ACQUISITION ANALYSIS.  Lehman Brothers performed a leveraged
acquisition analysis in order to ascertain the price which would be attractive
to a potential financial buyer based upon current market conditions. Lehman
Brothers assumed the following in this analysis: (i) a capital structure
comprised of $500 million in senior debt and $685 million in subordinated debt;
(ii) an equity investment that would achieve a rate of return of between 23-30%;
and (iii) an exit multiple of 11.0x 2003 projected EBITDA. Based on these
assumptions, the range of implied leveraged acquisition prices per share of
First Brands Common Stock was $29 to $33.
 
    DIVIDEND DISCOUNT ANALYSIS.  Lehman Brothers also performed a dividend
discount analysis to estimate the present value of dividends and the estimated
future value of the First Brands Common Stock. The present value of a share of
First Brands Common Stock was calculated by adding the present value of the per
share estimated dividend stream for the next five years and the present value of
the estimated price per share in 2003. Lehman Brothers assumed (i) an annual
dividend growth rate of approximately 10% beyond 1999; (ii) excess cash flow
generated by operations is applied to the reduction of debt over the period;
(iii) a range of multiples of earnings per share of 19.0x to 23.0x; and (iv) an
equity discount rate of 11%. Based on these assumptions, the indicated range of
values per share of First Brands Common Stock was $30.73 to $37.20.
 
                                       33

    CONTRIBUTION ANALYSIS.  Lehman Brothers utilized publicly available
historical financial data regarding First Brands and Clorox to calculate the
relative contributions of First Brands and Clorox to the pro forma combined
company with respect to revenues, operating income (defined as net income before
interest and tax) and net income for fiscal year 1998. In 1998, First Brands
would have contributed 30.5% of revenues, 18.5% of operating income and 15.5% of
net income to the combined company. Lehman Brothers compared such contributions
to the pro forma ownership of the combined company by the holders of First
Brands Common Stock. Such ownership would range from 11.8% at the Ratio Floor to
16.1% at the Ratio Cap, assuming exercise of all outstanding First Brands
options and all exercisable Clorox options.
 
    PRO FORMA ANALYSIS.  Based on the Exchange Ratio and the financial
projections of First Brands management, as extrapolated and adjusted as
described above, and third party research analysts with respect to the future
financial performance of Clorox on a stand-alone basis, Lehman Brothers
calculated the estimated pro forma financial results for the combined company.
Lehman Brothers noted that, assuming no cost savings as a result of the Merger
and excluding extraordinary charges, the Merger was estimated to be modestly
accretive to Clorox's stand alone earnings per share ("EPS") in fiscal year 1999
and fiscal year 2000.
 
    Lehman Brothers is an internationally recognized investment banking firm
and, as part of its investment banking activities, is regularly engaged in the
evaluation of businesses and their securities in connection with mergers and
acquisitions, negotiated underwritings, competitive bids, secondary
distributions of listed and unlisted securities, private placements and
valuations for corporate and other purposes. The First Brands Board selected
Lehman Brothers because of its expertise, reputation and familiarity with First
Brands and the consumer products industry in general and because its investment
banking professionals have substantial experience in transactions similar to the
Merger.
 
    First Brands has agreed to pay Lehman Brothers (1) a retainer of $300,000,
(2) a fee of $1 million for rendering its opinion and (3) a fee of $7.15 million
contingent upon consummation of the Merger against which the $300,000 retainer
and the $1 million opinion fee would be credited. First Brands also has agreed
to reimburse Lehman Brothers for reasonable expenses incurred by Lehman Brothers
in connection with Lehman Brothers' engagement and to indemnify Lehman Brothers
for certain liabilities that may arise out of its engagement and the rendering
of its opinion.
 
    In the ordinary course of its business, Lehman Brothers actively trades in
the debt and equity securities of First Brands and Clorox for its own account
and for the accounts of its customers and, accordingly, may at any time hold a
long or short position in such securities.
 
INTERESTS OF CERTAIN PERSONS IN THE MERGER
 
    GENERAL.  Certain executive officers and certain members of the First Brands
Board may be deemed to have interests in the Merger that are different from, or
in addition to, the interests of stockholders of First Brands generally. These
include, among other things, provisions in the Merger Agreement relating to
indemnification and the acceleration and/or payout of benefits under certain
agreements and employee benefit plans. The First Brands Board was aware of these
interests and considered them, among other matters, in approving the Merger
Agreement and the transactions contemplated thereby.
 
    The Merger Agreement provides that Clorox will, and will cause First Brands
to, assume and honor in accordance with their terms all employment, severance
and other compensation agreements, plans and arrangements which existed prior to
the execution of the Merger Agreement between First Brands and any of its
directors, officers or employees. Pursuant to the Merger Agreement, Clorox and
First Brands acknowledge and agree that the Merger constitutes a "Change of
Control" for all purposes pursuant to such agreements and arrangements and for
all purposes pursuant to the arrangements described below.
 
                                       34
<PAGE>
    The Merger Agreement also provides that for a period of 60 days immediately
following the Effective Time (as defined below under "--Effective Time"), Clorox
will, or will cause First Brands to, continue to employ those of First Brands'
officers who are "affiliates" within the meaning of Rule 144(a)(1) under the
Securities Act of 1933, as amended (the "Securities Act"), on financial terms no
less favorable as those in effect immediately prior to the Effective Time. In
addition, Clorox has agreed and acknowledged that such continued employment for
such 60-day period will not constitute a waiver on the part of any executive of
that executive's right to terminate his or her employment for "good reason"
(generally, an adverse change to the executive's authority, responsibilities,
job function or title) under the terms of such executive's Severance Agreement
(as defined below). In addition, Clorox has agreed to employ certain of such
executives on a part-time basis for an additional period of 12 months.
 
    INDEMNIFICATION AND INSURANCE.  The Merger Agreement provides that Clorox
and First Brands will indemnify (including the payment of any costs, judgments,
settlements or attorneys' fees and providing advances of expenses) each present
and former director, officer or employee of First Brands or any of its
subsidiaries, to the fullest extent permitted under applicable law, for
liabilities for acts or omissions occurring at or prior to the Effective Time.
The Merger Agreement also provides that Clorox will assume any indemnification
agreements in effect on October 18, 1998 and that any directors or officers of
First Brands who become directors or officers of Clorox will be entitled to all
indemnification rights afforded to other directors and officers of Clorox. See
"Comparison of Current First Brands Stockholder Rights and Rights of Clorox
Stockholders Following the Merger--Indemnification." The Merger Agreement also
provides that Clorox will maintain First Brands' current directors' and
officers' liability insurance coverage on terms no less favorable than the
policy in effect on October 18, 1998 for seven years after the date of the
Merger, but Clorox is not obligated to pay for any annual premium more than 200%
of the amount paid for premiums by First Brands as of the date of the Merger
Agreement.
 
    SEVERANCE AGREEMENTS.  First Brands has entered into severance agreements
with each of William V. Stephenson, Thomas H. Rowland, Donald A. DeSantis,
Patrick J. O'Brien, James S. Gracie, Mark E. Haglund, Joseph B. Furey and Einar
M. Rod (each, an "Executive" and each agreement, a "Severance Agreement"). Each
Severance Agreement provides generally that, in the event that the Executive's
employment with First Brands is terminated either (i) by First Brands other than
for "cause" or (ii) by the Executive with "good reason," in either case within
two years following a Change of Control, First Brands will pay to the Executive
severance payments and will provide to the Executive severance benefits as
follows: (a) a lump sum cash payment in an amount equal to the sum of (i) two
times the Executive's base salary (three times, in the case of Mr. Stephenson),
(ii) a pro rata portion (to the date of termination) of the Executive's annual
bonus for the year in which such termination occurs and (iii) the value of
adding three years of company service credit and three years of age for all
purposes under First Brands' Executive Retirement Plan and First Brands'
Retirement Program Plan (together, the "Retirement Plans"); (b) the
continuation, for two years following the Executive's termination of employment
(three years, in the case of Mr. Stephenson), of all medical, dental and life
insurance benefits in effect as of the date of termination, at no cost to the
Executive; (c) the continued eligibility to participate in the Executive
Retirement Plan; and (d) reasonable outplacement services. The Severance
Agreements further provide that (x) First Brands is obligated either (i) to
maintain in full force and effect and not adversely amend or affect the
Retirement Plans as in effect immediately prior to the Change of Control or (ii)
to provide benefits no less favorable to the Executive under substitute benefit
programs and (y) all payments made to the Executive that are calculated by
reference to the Retirement Plans must be calculated as though the Executive
were fully vested in the Retirement Plans. In addition, the Severance Agreements
provide that First Brands is obligated to pay an additional amount (the
"Additional Payment") sufficient to make such Executive whole with respect to
the excise tax imposed by the Code, and any taxes imposed on such additional
payments. It is anticipated that the Severance Agreements will be amended to
provide that some portion of the severance payment described in clause (a) above
shall be paid to certain of the Executives prior to December 31, 1998,
 
                                       35
<PAGE>
and that Clorox will indemnify and hold harmless each such Executive with
respect to any additional tax liability that such Executive may incur as a
result of receiving such amounts in 1998 rather than in 1999.
 
    OPTIONS.  First Brands maintains the Non-Employee Director Stock Option Plan
(the "Directors' Plan"). Each option granted under the Directors' Plan (each, a
"Director Option") becomes exercisable two years after the date of grant. Upon
separation of a director's service with the First Brands Board for reasons other
than death, disability or retirement, Director Options granted to such director
under the Directors' Plan, to the extent then exercisable, remain exercisable
for 60 days following the date of such separation of service. The Merger will
not affect the vesting of the Director Options.
 
    First Brands also maintains the 1998 Performance Stock Option and Incentive
Plan, the 1994 Performance Stock Option and Incentive Plan and the 1989 Long
Term Incentive Plan (collectively, the "Option Plans" and each option granted
under the Option Plans, an "Option"). Pursuant to each of the Option Plans, upon
a Change of Control of First Brands, all outstanding unvested Options to acquire
shares of First Brands Common Stock will become exercisable immediately in full.
Such Options shall remain exercisable for 60 days following the date of
termination of an optionholder's employment with First Brands.
 
    At the Effective Time, each Option and each Director Option to purchase
First Brands Common Stock will be deemed assumed by Clorox and will be deemed to
constitute an option to purchase shares of Clorox Common Stock (each, a "Clorox
Option") (see "The Merger Agreement--First Brands Stock Option Plans"). The
number of shares of Clorox Common Stock subject to a Clorox Option will be equal
to the number of shares of Clorox Common Stock (rounded down to the nearest
whole number) the holder of such Option or Director Option would have received
had he or she (a) exercised the Option or Director Option in full immediately
prior to the Effective Time and (b) received Clorox Common Stock, pursuant to
the terms of the Merger Agreement, in exchange for the shares of First Brands
Common Stock acquired upon such exercise of such Option or Director Option (the
number of shares of Clorox Common Stock received in such exchange, the
"Conversion Number"), at a price per share (rounded up to the nearest cent)
equal to (i) the aggregate exercise price for all shares of First Brands Common
Stock otherwise purchasable under the Option or Director Option, divided by (ii)
the Conversion Number.
 
    Based upon the Options outstanding as of December 15, 1998, the vesting of
Options relating to 1,222,750 shares of First Brands Common Stock, valued at
$47,840,094, based upon the per share closing price on December 15, 1998, held
by the executive officers of First Brands, would be accelerated upon the Merger.
 
    ANNUAL INCENTIVE PLAN.  First Brands' Annual Incentive Plan provides that,
following a Change of Control (as defined thereunder), no award granted
thereunder may be cancelled.
 
    DEFERRAL PLAN.  First Brands' Nonqualified Deferred Compensation Plan (the
"Deferral Plan") provides that, in the event that the committee administering
such plan believes that a Change of Control (as defined in the Deferral Plan) is
likely to occur, such committee will direct First Brands to establish a rabbi
trust and to contribute to such rabbi trust money or other property sufficient
to fund the present value of benefits to Deferral Plan participants.
 
    EXECUTIVE LIFE INSURANCE PLAN.  First Brands' Executive Life Insurance Plan
provides that, following a Change of Control, the First Brands Board may
authorize First Brands to assign its interest in each policy to a trust that
will continue coverage until such time as the arrangement would normally
terminate. It is expected that, immediately prior to the Change of Control,
First Brands will assign its interests in the Executive Life Insurance Plan to
such a trust.
 
    EMPLOYEE SEVERANCE PLAN.  Pursuant to the terms of the Merger Agreement,
First Brands (and, following the Effective Time, Clorox) has agreed to provide
severance payments and benefits to the
 
                                       36
<PAGE>
employees of First Brands in accordance with the terms set forth below (the
"Employee Severance Plan"). These severance payments and benefits will not be
made to any employee who is a party to an individual employment or severance
agreement.
 
    In the event the employment of any person who is an employee other than an
employee covered by a First Brands collective bargaining agreement (an
"Employee") immediately prior to the Effective Time is terminated by First
Brands without "cause" or by the Employee for "good reason," in either case
within 12 months following the Effective Time, the Employee will be entitled to
receive a lump sum severance payment equal to one-half of a month's salary per
year of service (with a minimum of two months' salary) (the period equal to
one-half of a month for each year of service being referred to as the "Severance
Period").
 
    Following the Employee's date of termination, for the Severance Period (or,
if longer, for the period required by any applicable law, and in any case
terminating on the date the Employee obtains employment which provides
substantially similar benefits), the Employee will receive all benefits under
any group hospitalization, health care plan, dental care plan, life or other
insurance or death benefit plan, or other present or future similar group
employee benefit plan or program of the employer for which Employees are
eligible, to the same extent as if the Employee has continued to be an Employee
during such Severance Period.
 
    SPECIAL SEVERANCE PLAN.  Pursuant to the terms of the Merger Agreement,
First Brands has agreed to establish the Special Severance Plan, pursuant to
which First Brands will pay a special severance payment to each Employee who is
a participant in the Annual Incentive Plan or who is a salaried plant employee
on the earlier to occur of (a) a termination date specified by Clorox or (b) a
termination of such Employee's employment by First Brands without "cause" or by
the Employee for "good reason." The special severance payment will be paid in a
single lump sum cash payment and will be equal to the higher of (x) such
Employee's estimated Annual Incentive Plan award with respect to the 1999 fiscal
year (if applicable) prorated to the applicable payment date and (y) two months'
salary. This special severance arrangement will terminate on the date that
payments under the Annual Incentive Plan with respect to the 1999 fiscal year
are paid. In no case will this special severance payment be duplicative of the
Employee's bonus with respect to the 1999 fiscal year.
 
FORM OF THE MERGER
 
    Pursuant to the Merger Agreement, and subject to the terms and conditions
thereof, at the Effective Time, Merger Sub will be merged with and into First
Brands, with First Brands as the Surviving Corporation, and the separate
existence of Merger Sub will cease.
 
    The certificate of incorporation and bylaws of Merger Sub immediately prior
to the Effective Time will be the certificate of incorporation and bylaws of the
Surviving Corporation at the Effective Time until duly amended. The directors
and officers of Merger Sub immediately prior to the Effective Time will be the
initial directors and officers of the Surviving Corporation.
 
MERGER CONSIDERATION
 
    As a result of the Merger, First Brands' stockholders will receive, for each
share of First Brands Common Stock that they own, whole shares of Clorox Common
Stock which will be determined according to one of the following exchange
ratios: (i) that number of shares of Clorox Common Stock equal to the quotient
of $39 divided by the Clorox Average Share Price (rounded to the nearest
thousandth of a share) if the Clorox Average Share Price is greater than $80 but
less than or equal to $115, (ii) 0.4875 of a share of Clorox Common Stock if the
Clorox Average Share Price is less than or equal to $80 or (iii) 0.3391 of a
share of Clorox Common Stock if the Clorox Average Share Price is greater than
$115.
 
    Clorox will not issue any fractional shares in the Merger. Instead, First
Brands stockholders will receive cash for any fractional share of Clorox Common
Stock owed to them in an amount equal to
 
                                       37
<PAGE>
(1) the fractional share that would otherwise be issuable multiplied by (2) the
closing price of Clorox Common Stock on the NYSE on the last trading day
immediately prior to the Effective Time.
 
EFFECTIVE TIME
 
    The effective time will occur upon the filing of all necessary documentation
(the "Merger Documents"), together with any required related certificates, with
the Secretary of State of the State of Delaware, in such form as required by,
and executed in accordance with the relevant provisions of, Delaware law (the
"Effective Time"). The filing of the Merger Documents will occur as soon as
practicable, but in no event later than three days, after the satisfaction or
waiver of the closing conditions set forth in the Merger Agreement. See "The
Merger Agreement--Conditions." The Merger Agreement may be terminated by mutual
agreement of both parties, by either party if the Merger has not been
consummated on or before June 30, 1999 (so long as the failure by the
terminating party to fulfill any obligation under the Merger Agreement is not
the cause of the failure of the Merger to occur prior to such date) and under
certain other conditions. See "The Merger Agreement--Conditions" and "The Merger
Agreement--Termination."
 
PROCEDURES FOR EXCHANGE OF FIRST BRANDS COMMON STOCK CERTIFICATES
 
    As a result of the Merger and without any action on the part of the First
Brands stockholders, each share of First Brands Common Stock issued and
outstanding immediately prior to the Effective Time will be converted into the
right to receive that number of shares of fully paid and nonassessable shares of
Clorox Common Stock as determined by the Exchange Ratio.
 
    Each holder of a certificate evidencing outstanding shares of First Brands
Common Stock (a "First Brands Certificate") upon consummation of the Merger will
cease to have any rights with respect to such First Brands Common Stock, except
the right to receive, without interest, shares of Clorox Common Stock, any
distributions made by First Brands prior to the Effective Time, and cash in lieu
of fractional shares (as described in "The Merger Agreement--Conversion of
Shares") upon the surrender of such First Brands Certificate. If, prior to the
Effective Time, either Clorox or First Brands should split or combine their
common stock, or pay a stock dividend or other stock distribution in, or in
exchange of, shares of their common stock, or engage in any similar transaction,
then the Exchange Ratio will be appropriately adjusted to reflect such split,
combination, dividend, exchange, distribution or similar transaction.
 
ANTICIPATED ACCOUNTING TREATMENT
 
    The Merger is intended to qualify as a pooling of interests for accounting
and financial reporting purposes. Under this method of accounting, the recorded
historical cost basis of the assets and liabilities of Clorox and First Brands
will be carried forward to the operations of the combined company at their
historical recorded amounts. Results of operations of the combined company will
include income of Clorox and First Brands for the entire fiscal period in which
the combination occurs, and the historical results of operations of the separate
companies for fiscal years prior to the Merger will be combined and reported as
the results of operations of the combined company. No adjustments have been made
to the unaudited combined condensed pro forma financial statements of Clorox and
First Brands to conform the accounting policies of the combined company as the
nature and amounts of such adjustments are deemed insignificant.
 
    Consummation of the Merger is conditioned upon receipt by each of Clorox and
First Brands of a letter from their respective independent public accountants
stating that, in their respective opinions, they concur with the conclusions of
the management of Clorox and First Brands that the criteria for pooling of
interests accounting, which can be assessed at that time, have been met. See
"The Merger Agreement--Conditions" and "Risk Factors--Failure to Qualify for
Pooling of Interests Accounting Treatment May Impact Reported Operating
Results." However, some of the conditions to be met for pooling of interests
accounting cannot be fully assessed until the passage of specified periods of
time
 
                                       38
<PAGE>
after the Effective Time, as certain of the conditions for pooling of interests
accounting address transactions occurring within such specified periods of time.
Certain events, including certain transactions with respect to Clorox Common
Stock or First Brands Common Stock by affiliates of Clorox and First Brands,
respectively, may prevent the Merger from qualifying as a pooling of interests
for accounting and financial reporting purposes. For information concerning
certain restrictions to be imposed on the transferability of Clorox Common Stock
to be received by affiliates in order, among other things, to ensure the
availability of pooling of interests accounting treatment, see "The
Merger--Resale Restrictions."
 
REGULATORY APPROVALS
 
    Under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 (the "HSR
Act"), and the rules promulgated thereunder by the Federal Trade Commission (the
"FTC"), the Merger cannot be consummated until notifications have been given and
certain information has been furnished to the FTC and the Antitrust Division of
the Department of Justice (the "Antitrust Division") and specified waiting
period requirements have been satisfied. Clorox and First Brands filed
notification and report forms under the HSR Act with the FTC and the Antitrust
Division on November 10, 1998. The waiting period under the HSR Act expired at
11:59 p.m., Eastern Standard Time, on December 10, 1998.
 
    On November 23, 1998, Clorox submitted a pre-merger notification of the
Merger to the German Cartel Office. The Cartel Office notified Clorox on
November 27, 1998 that the transaction would not be prohibited. Clorox and First
Brands may make additional regulatory filings in other foreign jurisdictions.
 
    At any time before or after consummation of the Merger, the Antitrust
Division or the FTC, or any state, could take such action under the antitrust
laws as it deems necessary or desirable in the public interest, including
seeking to enjoin the consummation of the Merger or seeking divestiture of
particular assets of Clorox or First Brands. Private parties also may seek to
take legal action under the antitrust laws under certain circumstances. In
addition, non-United States governmental and regulatory authorities may seek to
take action under applicable antitrust laws. There can be no assurance that a
challenge to the Merger will not be made or, if such challenge is made, that
Clorox will prevail.
 
    The obligations of Clorox and First Brands to consummate the Merger are
subject to the condition that there be no preliminary or permanent injunction or
other order by any court of competent jurisdiction or other legal restraint or
prohibition that prevents consummation of the Merger, that there be no
litigation by any governmental entity seeking any of the same, and that there be
no statute, rule, regulation, executive order, stay, decree or judgment by any
court or governmental authority deemed applicable to the Merger that makes the
consummation of the Merger illegal. In addition, the obligations of the parties
to consummate the Merger are subject to there being no action taken or any rule,
regulation, order or statute enacted, entered or enforced by any governmental
entity that imposes any condition or restriction upon Clorox, First Brands or
any of their subsidiaries (including, without limitation, the disposition of
assets by any of them) which in any case would so materially adversely impact
the economic or business benefits of the Merger such that a reasonable business
person in that situation would not proceed with the Merger. For a more complete
description of these conditions, see "The Merger Agreement--Conditions." Either
Clorox or First Brands may terminate the Merger Agreement if a court of
competent jurisdiction or governmental, regulatory or administrative agency or
commission shall have issued a non-appealable, final order, decree or ruling or
taken any other action, having the effect of permanently restraining, enjoining
or otherwise prohibiting the Merger, provided that the party relying on such
order, decree or ruling has complied with its obligations with respect to using
its best efforts to consummate the Merger and to cause the Merger to qualify as
a tax-free reorganization. See "The Merger Agreement--Conditions" and "The
Merger Agreement-- Termination."
 
                                       39
<PAGE>
CERTAIN OTHER EFFECTS OF THE MERGER; DELISTING OF FIRST BRANDS SHARES
 
    After the Merger, First Brands stockholders will become stockholders of
Clorox. The rights of all such stockholders will be governed by the certificate
of incorporation and bylaws of Clorox. For a description of the difference
between the rights of Clorox and First Brands stockholders, see "Comparison of
Rights of Clorox Stockholders and First Brands Stockholders."
 
    If the Merger is consummated, shares of First Brands Common Stock will cease
to be listed on the NYSE. In addition, First Brands will deregister the First
Brands Common Stock under the Exchange Act and, accordingly, will no longer be
required to file periodic reports pursuant to the Exchange Act.
 
NO DISSENTERS' RIGHTS
 
    Section 262 of the Delaware General Corporation Law (the "DGCL") provides
appraisal rights (sometimes referred to as "dissenters' rights") to stockholders
of Delaware corporations in certain situations. However, Section 262 appraisal
rights are not available to stockholders of a corporation, such as First Brands,
(a) whose securities are listed on a national securities exchange, and (b) whose
stockholders are not required to accept in exchange for their stock anything
other than stock of another corporation listed on a national securities exchange
and cash in lieu of fractional shares. Because the First Brands Common Stock is
traded on a national securities exchange, the NYSE, and because the First Brands
stockholders are being offered Clorox Common Stock, which is also traded on the
NYSE, and cash in lieu of fractional shares, stockholders of First Brands will
not have appraisal rights with respect to the Merger.
 
MATERIAL FEDERAL INCOME TAX CONSEQUENCES
 
    The following discussion summarizes the material federal income tax
consequences of the Merger that are applicable to First Brands stockholders. It
is based on the Code, applicable U.S. Treasury Regulations, judicial authority,
and administrative rulings and practice, all as of the date of this Proxy
Statement/Prospectus and all of which are subject to change, including changes
with retroactive effect. The discussion below does not address any state, local
or foreign tax consequences of the Merger. The tax treatment of a stockholder
may vary depending upon the stockholder's particular situation, and certain
stockholders (including individuals who hold options in respect of First Brands
Common Stock, insurance companies, tax-exempt organizations, financial
institutions or broker-dealers, persons who are neither citizens nor residents
of the United States, and persons who hold First Brands Common Stock as part of
a hedge, straddle or conversion transaction) may be subject to special rules not
discussed below. The following discussion assumes that First Brands Common Stock
is held as a capital asset at the Effective Time. Neither Clorox nor First
Brands has requested or will request an advance ruling from the Internal Revenue
Service as to the tax consequences of the Merger.
 
    EACH FIRST BRANDS STOCKHOLDER IS URGED TO CONSULT THEIR TAX ADVISOR AS TO
THE PARTICULAR TAX CONSEQUENCES OF THE MERGER TO THEM, INCLUDING THE
APPLICABILITY AND EFFECT OF ANY STATE, LOCAL OR FOREIGN LAWS, AND THE EFFECT OF
POSSIBLE CHANGES IN APPLICABLE TAX LAWS.
 
    The obligations of First Brands and Clorox to consummate the Merger are
conditioned upon the receipt by First Brands and Clorox of opinions (the "Tax
Opinions") of Skadden, counsel to First Brands, and Morrison & Foerster LLP,
counsel to Clorox, that on the basis of the facts, representations and
assumptions set forth or referred to therein, for U.S. federal income tax
purposes, the Merger will qualify as a tax-free reorganization under Section
368(a) of the Code, and that each of Clorox, Merger Sub and First Brands will be
a party to the reorganization within the meaning of Section 368(b) of the Code
(such opinions, collectively, the "Tax Opinions"). Provided that the Merger so
qualifies,
 
                                       40
<PAGE>
        (i) Except for any cash received in lieu of fractional shares, a First
    Brands stockholder will not recognize any gain or loss as a result of the
    receipt of Clorox Common Stock pursuant to the Merger.
 
        (ii) A First Brands stockholder's aggregate tax basis for the shares of
    Clorox Common Stock received pursuant to the Merger, including any
    fractional share interest for which cash is received, will equal such
    stockholder's aggregate tax basis in shares of First Brands Common Stock
    held immediately before the Merger.
 
       (iii) A First Brands stockholder's holding period for the shares of
    Clorox Common Stock received pursuant to the Merger, including any
    fractional share interest for which cash is received, will include the
    period during which the shares of First Brands Common Stock were held.
 
        (iv) Cash received by a First Brands stockholder in lieu of a fractional
    share interest of Clorox Common Stock will be treated as having been
    received in exchange for such fractional share interest and capital gain or
    loss will be recognized in an amount equal to the difference between the
    amount of cash received and the portion of the tax basis allocable to such
    fractional interest.
 
    The Tax Opinions are based upon certain facts, representations and
assumptions set forth or referred to therein and the continued accuracy and
completeness of certain representations made by Clorox, Merger Sub and First
Brands, including representations in certificates to be delivered to counsel by
the management of each of Clorox and First Brands which, if incorrect in certain
material respects, would jeopardize the conclusions reached by counsel in their
opinions. In addition, in the event that Clorox or First Brands is unable to
obtain the Tax Opinions, each of Clorox and First Brands is permitted under the
Merger Agreement to waive the receipt of such Tax Opinions as a condition to
such party's obligation to consummate the Merger. As of the date of this Proxy
Settlement/Prospectus, neither Clorox nor First Brands intends to waive the
receipt of the Tax Opinions as a condition to such party's obligation to
consummate the Merger. In the event of such a failure to obtain the Tax
Opinions, and either Clorox or First Brands determines to waive such condition
to the consummation of the Merger, First Brands will resolicit the votes of its
stockholders to approve consummation of the Merger.
 
RESALE RESTRICTIONS AND LOCKUP AGREEMENTS
 
    This Proxy Statement/Prospectus does not cover resales of the Clorox Common
Stock to be received by the stockholders of First Brands upon consummation of
the Merger, and no person is authorized to make any use of this Proxy
Statement/Prospectus in connection with any such resale.
 
    All shares of Clorox Common Stock received by First Brands stockholders in
the Merger will be freely transferable, except that shares of Clorox Common
Stock received by persons who are deemed to be "affiliates" (as such term is
defined under the Securities Act) of First Brands may be resold by them only in
transactions permitted by the resale provisions of Rule 145 (or Rule 144 in the
case of such persons who become affiliates of Clorox) promulgated under the
Securities Act or as otherwise permitted under the Securities Act. Persons who
may be deemed to be affiliates of Clorox or First Brands generally include
individuals or entities that control, are controlled by, or are under common
control with, such party and may include certain officers and directors of
Clorox or First Brands as well as significant stockholders.
 
    Commission guidelines regarding qualification for the use of the pooling of
interests method of accounting also limit sales by affiliates of the acquiring
and acquired companies in a business combination. Commission guidelines indicate
further that the pooling of interests method of accounting generally will not be
challenged on the basis of sales by affiliates of the acquiring or acquired
company if they do not dispose of any of the shares they own or shares they
receive in connection with a Merger
 
                                       41
<PAGE>
during the period beginning 30 days before the Merger and ending when financial
results covering at least 30 days of combined operations have been published.
See "The Merger--Accounting Treatment."
 
    The Merger Agreement requires First Brands to use its best efforts to cause
each of its affiliates to execute a written agreement restricting the
disposition by such affiliate of the shares of Clorox Common Stock to be
received by such affiliate in the Merger.
 
DIVIDEND POLICY
 
    Clorox currently expects to declare regularly scheduled dividends consistent
with its policy prior to the Merger, which is to pay dividends quarterly at a
rate of $0.36 per share of Clorox Common Stock (an annual rate of $1.44). Future
dividends will be at the discretion of the Clorox Board and will be determined
after consideration of a number of factors, including, among others, Clorox's
earnings, financial condition, cash flows from operations, current and
anticipated cash needs and expansion plans and any restrictions that may be
imposed under Clorox's current and future credit facilities.
 
    Under the terms of the Merger Agreement, First Brands is not permitted to
declare, set aside, make or pay any distribution in respect of its equity
securities, other than its normal quarterly dividend consistent with past
practices, during the period from the date of the Merger Agreement until the
earlier of the termination of the Merger Agreement or the Effective Time.
 
                              THE MERGER AGREEMENT
 
    THE FOLLOWING IS A BRIEF SUMMARY OF THE MATERIAL PROVISIONS OF THE MERGER
AGREEMENT, A COPY OF WHICH IS ATTACHED AS APPENDIX A TO THIS PROXY
STATEMENT/PROSPECTUS AND IS INCORPORATED HEREIN BY REFERENCE. THIS SUMMARY IS
QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE FULL TEXT OF THE MERGER AGREEMENT.
 
THE MERGER
 
    The terms and conditions of the Merger Agreement provide that, at the
Effective Time, Merger Sub will be merged with and into First Brands, with First
Brands as the Surviving Corporation, and Merger Sub will cease to exist.
 
    The certificate of incorporation and bylaws of Merger Sub immediately prior
to the Effective Time will be the certificate of incorporation and bylaws of the
Surviving Corporation at the Effective Time until duly amended, and the
directors and officers of Merger Sub immediately prior to the Effective Time
will be the initial directors and officers of the Surviving Corporation.
 
CONVERSION OF SECURITIES
 
    As a result of the Merger and without any action on the part of the holders
thereof, each share of First Brands Common Stock issued and outstanding
immediately prior to the Effective Time (excluding shares held by Clorox, First
Brands or any of their subsidiaries, which will be cancelled) will be converted
into the right to receive (i) that fraction of a share of Clorox Common Stock
equal to the quotient of $39 divided by the Clorox Average Share Price (rounded
to the nearest thousandth of a share) if the Clorox Average Share Price is
greater than $80 but less than or equal to $115, (ii) 0.4875 of a share of
Clorox Common Stock if the Clorox Average Share Price is less than or equal to
$80, or (iii) 0.3391 of a share of Clorox Common Stock if the Clorox Average
Share Price is greater than $115. At the Effective Time, each share of First
Brands Common Stock so converted will cease to be outstanding, and will be
cancelled and retired, except as described below.
 
                                       42
<PAGE>
    The Merger Agreement provides that the Clorox Average Share Price will be
calculated based on the ten trading day period preceding the fifth trading day
prior to the Effective Time, and therefore the number of shares of Clorox Common
Stock constituting the Merger consideration will be fixed at that time. The
market price of Clorox Common Stock and hence the value of the Merger
Consideration could fluctuate with the performance of Clorox and general market
conditions up to the date of determination of the Exchange Ratio. In addition,
the market price of the Clorox Common Stock could fluctuate during the five
trading day period between the determination of the Clorox Average Share Price
and the Effective Time. Thus, the value of the Merger Consideration at the
Effective Time may be less than the value of the Merger Consideration as
determined at any point in time prior to the Effective Time. See "Risk
Factors--Adjustable Exchange Ratio."
 
    Each holder of a First Brands Certificate upon consummation of the Merger
will cease to have any rights with respect to such First Brands Common Stock,
except the right to receive, without interest, shares of Clorox Common Stock,
any distributions made by First Brands prior to the Effective Time and cash in
lieu of fractional shares upon the surrender of such First Brands Certificate.
If, prior to the Effective Time, either Clorox or First Brands should split or
combine the shares of Clorox Common Stock or First Brands Common Stock, or pay a
stock dividend or other stock distribution in, or in exchange of, shares of
Clorox Common Stock or First Brands Common Stock, or engage in a reorganization
or recapitalization or any similar transaction, then the Exchange Ratio will be
appropriately adjusted to reflect such split, combination, dividend, exchange,
distribution or similar transaction.
 
FIRST BRANDS STOCK OPTION PLANS
 
    As of the Effective Time, each of the options to acquire shares of First
Brands Common Stock not expired as of the Effective Date, will be assumed by
Clorox, and each option will be converted into an option to purchase that number
of shares of Clorox Common Stock (rounded down to the nearest whole number)
which the holder thereof would have been entitled to receive under the Merger
Agreement had the stock option been exercised immediately prior to the Effective
Time, and the replacement option will have a per share exercise price equal to
the aggregate exercise price for First Brands Common Stock subject to the option
divided by the number of shares of Clorox Common Stock purchasable under the
assumed option.
 
    Subject to the consent of the holders thereof, each limited stock
appreciation right ("LSAR") issued and outstanding under any of the Option Plans
or the Director Plan will be cancelled effective immediately prior to the
Effective Time and at the same time the tandem stock option will be assumed
pursuant to the terms above.
 
    Except as described above, the assumed stock options will be subject to the
same terms and conditions (including, without limitation, vesting provisions) as
were applicable to such stock options immediately prior to the Effective Time,
with such adjustments as are appropriate to preserve the value in such awards
with no detrimental effects on the holders thereof. Consummation of the Merger
will not be treated as a termination of employment for purposes of such stock
options.
 
    The assumption of the Options enables the holders thereof to hold options to
acquire Clorox Common Stock after the Merger. Options granted under the Option
Plans immediately accelerate and vest upon consummation of the Merger. As of
December 15, 1998, there were outstanding options to purchase an aggregate of
2,699,002 shares of First Brands Common Stock, at a weighted average exercise
price of approximately $18.10 per share (at exercise prices ranging from $9.50
to $26.00 per share).
 
    Clorox will take all corporate action necessary to reserve for issuance a
sufficient number of shares of Clorox Common Stock for delivery pursuant to the
terms of all assumed First Brands stock options.
 
                                       43
<PAGE>
EXCHANGE OF SHARES
 
    As soon as reasonably practicable after the Effective Time, First Chicago
Trust Company of New York (the "Exchange Agent") will mail to each holder of
record of First Brands Common Stock (i) a letter of transmittal and (ii)
instructions for use in effecting the surrender of the First Brands Certificates
in exchange for certificates representing shares of Clorox Common Stock and, in
lieu of any fractional shares thereof, cash. Upon surrender of a First Brands
Certificate to the Exchange Agent together with such letter of transmittal, duly
executed, and any other customary documents as may be reasonably required, the
holder of such First Brands Certificate will be entitled to receive in exchange
therefor (i) a certificate representing a number of whole shares of Clorox
Common Stock equal to the Exchange Ratio multiplied by the number of shares of
First Brands Common Stock represented by the certificate, (ii) any dividends or
other distributions of First Brands made prior to the Effective Time to which
such holder is entitled and (iii) a check representing the amount of cash in
lieu of a fractional share of Clorox Common Stock, if any, which such holder has
the right to receive in respect of the First Brands Certificate so surrendered.
See "--Conversion of Securities." FIRST BRANDS STOCKHOLDERS SHOULD NOT SEND IN
THEIR FIRST BRANDS CERTIFICATES UNTIL THEY RECEIVE A LETTER OF TRANSMITTAL.
 
    No fractional shares of Clorox Common Stock will be issued pursuant to the
Merger. In lieu thereof, cash adjustments will be paid in an amount equal to (i)
the fraction of a share of Clorox Common Stock that would otherwise be issuable,
multiplied by (ii) the closing price of Clorox Common Stock on the NYSE
Composite Transaction Tape on the last trading day immediately prior to the
Effective Time.
 
    After the Effective Time and until surrendered, each First Brands
Certificate will be deemed to represent only the right to receive upon surrender
a certificate representing whole shares of Clorox Common Stock, dividends or
other distributions of First Brands made prior to the Effective Time and cash in
lieu of fractional shares of Clorox Common Stock. No dividends or other
distributions declared or made with a record date after the Effective Time will
be paid to the holder of any unsurrendered First Brands Certificate with respect
to the shares of Clorox Common Stock represented thereby, and no cash in lieu of
fractional shares will be paid to any such holder, until the holder of record of
such First Brands Certificate surrenders such First Brands Certificate. Subject
to the effect of applicable laws, following surrender of any such Certificate,
there will be paid to the record holder of the new certificates representing
whole shares of Clorox Common Stock issued in exchange therefor, without
interest, (i) at the time of such surrender, the amount of any cash payable in
lieu of fractional shares of Clorox Common Stock to which such holder is
entitled and the amount of dividends or other distributions with a record date
after the Effective Time previously paid with respect to such whole shares of
Clorox Common Stock, and (ii) at the appropriate payment date, the amount of
dividends or other distributions with a record date after the Effective Time but
prior to surrender and a payment date subsequent to surrender payable with
respect to such whole shares of Clorox Common Stock.
 
    If any certificates for shares of Clorox Common Stock are to be issued in a
name other than that in which the First Brands Certificate surrendered in
exchange therefor is registered, the person requesting such exchange must (i)
pay to Clorox or any agent designated by it any transfer or other taxes required
by reason thereof, or (ii) establish to the satisfaction of Clorox or any agent
designated by it that such tax has been paid or is not applicable.
 
    At the Effective Time, the stock transfer books of First Brands will be
closed and no further transfers of shares of First Brands Common Stock will be
made. If, after the Effective Time, First Brands Certificates are presented to
the Surviving Corporation for any reason, they will be cancelled and exchanged
as described above.
 
    No party to the Merger Agreement is or will be liable to a holder of shares
of First Brands Common Stock for any shares of Clorox Common Stock or dividends
thereon or the cash payment for
 
                                       44
<PAGE>
fractional interests delivered to a public official pursuant to applicable
abandoned property, escheat or similar laws.
 
    Clorox or the Exchange Agent will be entitled to deduct and withhold from
the consideration otherwise payable pursuant to the Merger Agreement such
amounts as Clorox or the Exchange Agent is required to deduct and withhold under
the Code, or any provision of state, local or foreign tax law, with respect to
the making of such payment. To the extent that amounts are so withheld by Clorox
or the Exchange Agent, such withheld amounts shall be treated for all purposes
of the Merger Agreement as having been paid to the person in respect of whom
such deduction and withholding was made by Clorox or the Exchange Agent.
 
    In the event that any First Brands Certificate has been lost, stolen or
destroyed, upon (i) the making of an affidavit of that fact by the person
claiming such First Brands Certificate to be lost, stolen or destroyed, and (ii)
if required by Clorox, in its reasonable discretion, the posting by such person
of a bond in such sum as Clorox may direct as indemnity against any claim that
may be made against Clorox with respect to such First Brands Certificate, Clorox
will issue or cause to be issued in exchange for such First Brands Certificate
the number of whole shares of Clorox Common Stock and cash in lieu of fractional
shares into which the shares of First Brands Common Stock represented by the
First Brands Certificate are converted in the Merger.

      change of control; or
 
    - take, or agree in writing or otherwise to take, any of the actions
      described above, or any action which would make any of the representations
      or warranties of First Brands contained in the Merger Agreement untrue or
      incorrect or prevent First Brands from performing or cause First Brands
      not to perform its covenants under the Merger Agreement.
 
NO SOLICITATION
 
    The Merger Agreement provides that, subject to the following paragraph,
First Brands will not, and will use its reasonable best efforts to cause its
subsidiaries, its representatives and the representatives of its subsidiaries to
not, initiate, solicit, encourage or take any action to facilitate any inquiries
about or the making of any proposal to effect an Alternative Transaction (as
defined below) or to enter into discussions about any Alternative Transaction.
 
    However, if the First Brands Board determines in good faith after
consultation with Skadden that its fiduciary duties under Delaware law require
that it consider an Alternative Transaction, then the First Brands Board may
furnish information or enter into discussions or negotiations with an entity
making an unsolicited bona fide proposal relating to an Alternative Transaction.
In such circumstance, First Brands is required to enter into a confidentiality
agreement with such entity prior to furnishing any information, and the terms of
such confidentiality agreement cannot be more favorable to the third party than
the terms of the confidentiality agreement between Clorox and First Brands.
First Brands
 
                                       47
<PAGE>
must communicate to Clorox the terms of any Alternative Transaction the terms of
which it feels are superior to the terms of the Merger Agreement (if financing
is also committed), unless after consulting with Skadden it determines that its
fiduciary duties under Delaware Law prevent such action.
 
    The First Brands Board may withdraw or modify its recommendation in favor of
the Merger if
 
    - First Brands receives an Alternative Transaction the terms and conditions
      of which in the judgment of the First Brands Board are more favorable than
      the terms of the Merger Agreement, and for which financing is committed,
      and
 
    - upon the advice of Skadden, the Board determines in good faith that it is
      necessary to do so in order to fulfill its fiduciary duties to its
      stockholders under Delaware law.
 
    "Alternative Transaction" means any inquiry, proposal or offer from any
person relating to any
 
    - direct or indirect acquisition or purchase of a business that constitutes
      15% or more of the net revenues, net income or the assets of First Brands
      and its subsidiaries, taken as a whole,
 
    - direct or indirect acquisition or purchase of 15% or more of any class of
      equity securities of First Brands or any of its subsidiaries whose
      business constitutes 15% or more of the net revenues, net income or assets
      of First Brands and its subsidiaries, taken as a whole,
 
    - tender offer or exchange offer that if consummated would result in any
      person beneficially owning 15% or more of any class of equity securities
      of First Brands or any of its subsidiaries whose business constitutes 15%
      or more of the net revenues, net income or assets of First Brands and its
      subsidiaries, taken as a whole, or
 
    - merger, consolidation, business combination, capitalization, liquidation,
      dissolution or similar transaction involving First Brands or any of its
      subsidiaries whose business constitutes 15% or more of the net revenues,
      net income or assets of First Brands and its subsidiaries, taken as a
      whole, other than the transactions contemplated by the Merger Agreement.
 
DIRECTOR AND OFFICER INDEMNIFICATION
 
    For a description of the indemnification of First Brands directors and
officers pursuant to the Merger, see "The Merger--Interests of Certain Persons
in the Merger--Indemnification and Insurance."
 
ACCESS AND INFORMATION
 
    The Merger Agreement provides that, until the Effective Time, First Brands
and its subsidiaries will afford to Clorox access to all of its properties,
books, contracts, commitments and records. Furthermore, First Brands will
furnish promptly to Clorox all information concerning its business, properties
and personnel as Clorox may reasonably request and will make available to Clorox
the appropriate individuals (including attorneys, accountants and other
professionals) for discussion of its properties and personnel as Clorox may
reasonably request.
 
    Clorox will hold any information which is nonpublic in confidence in
accordance with a confidentiality agreement between it and First Brands.
 
    Clorox and First Brands will each obtain the approval of the other prior to
issuing any press release or any other public statement with respect to the
Merger or the Merger Agreement, provided, however, that a party may, without
prior written consent of the other party, issue such press release or make such
public statement as may upon the advice of counsel be required by law or the
NYSE if it has used all reasonable efforts to consult with the other party.
 
                                       48
<PAGE>
AGREEMENTS RELATING TO APPROVAL OF THE MERGER
 
    The Merger Agreement provides that Clorox and First Brands will each use
their reasonable efforts to obtain all consents, waivers, approvals,
authorizations or orders (including, without limitation, all governmental and
regulatory rulings and approvals). Clorox and First Brands will make all filings
(including, without limitation, all filings with governmental or regulatory
agencies) required in connection with the consummation by them of the
transactions contemplated by the Merger Agreement. Clorox and First Brands will
furnish all information required to be included in any such application or other
filing. Except where prohibited by applicable statutes and regulations, and
subject to the confidentiality agreement between Clorox and First Brands, each
party will promptly provide the other (or its counsel) with copies of all
filings made by such party with any state or federal government entity in
connection with the transactions contemplated by the Merger Agreement.
 
FIRST BRANDS' EMPLOYEE BENEFITS
 
    The Merger Agreement provides that Clorox will give all employees of First
Brands and its subsidiaries, employed at the Effective Time, full credit for
their prior service with First Brands or any subsidiary for purposes of
eligibility, vesting and benefit accrual (but excluding benefit accrual under
any defined benefit pension plans) under any employee benefit plans or
arrangements maintained by Clorox to the same extent recognized by First Brands
immediately prior to the Effective Time. Clorox will further waive any
pre-existing condition exclusions and waiting periods and provide credit for any
co-payments or deductibles made prior to the Effective Time with respect to
participation, coverage or out-of-pocket requirements for such employees, except
for limitations or waiting periods that are already in effect with respect to
such employees under First Brands' plans not satisfied prior to the Effective
Time.
 
    Clorox also agrees to provide, for a period of two years immediately
following the Effective Time, coverage and benefits to such employees that, in
the aggregate, are no less favorable than those provided immediately prior to
the Effective Time.
 
    Clorox also agrees to assume and honor certain severance arrangements to be
implemented by First Brands. See "The Merger--Interests of Certain Persons in
the Merger."
 
ADDITIONAL AGREEMENTS
 
    The Merger Agreement provides that First Brands and Clorox will cooperate
with each other and use all reasonable efforts to take, or cause to be taken,
all action and to do, or cause to be done, all things necessary, proper or
advisable to consummate and make effective the transactions contemplated by the
Merger Agreement. However, Clorox will not be obligated to divest, abandon,
license or take similar action with respect to any assets of Clorox or First
Brands which, in the reasonable judgment of Clorox, would so materially
adversely impact the transactions that a reasonable business person in such
situation would not proceed with the Merger.
 
CONDITIONS
 
    The obligations of Clorox and First Brands to effect the Merger are subject
to the satisfaction or waiver of certain conditions, including, among others:
 
        EFFECTIVE REGISTRATION STATEMENT.  The Registration Statement shall have
    been declared effective by the Commission under the Securities Act and the
    Merger shall have been accounted for in such Registration Statement as a
    pooling of interests transaction;
 
        NO INJUNCTION.  No temporary restraining order, preliminary or permanent
    injunction or other order issued by any court of competent jurisdiction or

    Merger shall be in effect and no litigation by any governmental entity
 
                                       49
<PAGE>
    seeking any of the foregoing shall have been commenced, and there shall not
    be any action taken, or any statute, rule, regulation or order enacted,
    entered, enforced or deemed applicable to the Merger, which makes the
    consummation of the Merger illegal;
 
        REGULATORY APPROVAL.  There shall not be any action taken, or law or
    regulation enacted, entered, enforced or deemed applicable to the Merger, by
    any federal or state governmental entity which, in connection with the grant
    of a consent or the lapse of a waiting period which is necessary for the
    consummation of the Merger, imposes any condition or restriction upon the
    Surviving Corporation or, under certain circumstances, Clorox, including,
    without limitation, requirements relating to the disposition of assets,
    which in any such case would so materially adversely impact the economic or
    business benefits of the transactions contemplated by the Merger Agreement,
    such that a reasonable business person in such a situation would not proceed
    with the consummation of the Merger;
 
        ACCOUNTANT'S OPINION.  First Brands and Clorox shall have received (i) a
    letter addressed to Clorox from Deloitte & Touche LLP, dated the date of the
    Merger, in form and substance reasonably satisfactory to Clorox and (ii) a
    letter addressed to First Brands from KPMG Peat Marwick LLP, dated the date
    of the Merger, in form and substance reasonably satisfactory to First
    Brands, in each case to the effect that the Merger qualifies for "pooling of
    interests" accounting treatment for financial purposes and that such
    accounting treatment is in accordance with U.S. GAAP;
 
        HSR ACT.  The waiting period (and any extension thereof) applicable to
    the consummation of the Merger under the HSR Act shall have expired or been
    terminated;
 
        STOCK EXCHANGE LISTING.  The shares of Clorox Common Stock issuable to
    the First Brands stockholders in the Merger shall have been approved for
    listing on the NYSE, subject to official notice of issuance; and
 
        SHAREHOLDER APPROVAL.  The Merger Agreement shall have been approved and
    adopted by the requisite vote of the stockholders of First Brands.
 
ADDITIONAL CONDITIONS TO THE OBLIGATIONS OF CLOROX AND MERGER SUB
 
    The obligations of Clorox and Merger Sub to effect the Merger are also
subject to the following additional conditions:
 
        REPRESENTATIONS AND WARRANTIES TRUE.  The representations and warranties
    of First Brands contained in the Merger Agreement shall be true and correct
    on and as of the Effective Time, except (i) for changes contemplated by the
    Merger Agreement, (ii) those representations and warranties which address
    matters only as of a particular date (which shall remain true and correct as
    of such date) and (iii) where the failure of such representations and
    warranties to be so true and correct (without giving effect to any
    limitation as to "materiality" or "material adverse effect" set forth
    therein) would not, individually or in the aggregate, have a material
    adverse effect on First Brands, with the same force and effect as if made on
    and as of the Effective Time;
 
        COMPLIANCE WITH COVENANTS.  First Brands shall have performed or
    complied in all material respects with all agreements and covenants required
    by the Merger Agreement to be performed or complied with by it on or prior
    to the Effective Time;
 
        CONSENTS AND APPROVALS RECEIVED.  All material consents, waivers,
    approvals, authorizations or orders required to be obtained, and all filings
    required to be made ("Material Consents"), by First Brands for the
    authorization, execution and delivery of the Merger Agreement and the
    consummation by it of the transactions contemplated in the Merger Agreement
    shall have been obtained and made by First Brands, except where the failure
    to receive such Material Consents would not have a material adverse effect
    on First Brands or Clorox;
 
                                       50
<PAGE>
        NO MATERIAL ADVERSE CHANGE.  Since October 18, 1998, there shall have
    been no change in First Brands or any First Brands subsidiary having,
    individually or in the aggregate, a material adverse effect on First Brands;
 
        AFFILIATE AGREEMENTS.  Clorox shall have received from each person who
    is identified as an "affiliate" of First Brands for purposes of Rule 145
    under the Securities Act (an "Affiliate"), an affiliate agreement relating
    to, among other things, restrictions on such Affiliate's sale of Clorox
    Common Stock, and such Affiliate agreement shall be in full force and effect
    as of the Effective Time;
 
        ADVISORS' REMUNERATION.  Clorox shall have received a copy of final
    invoices from First Brands' financial advisors, accountants and counsel at
    least one business day prior to the Merger, and the sum of all fees paid and
    to be paid to such parties by First Brands shall be no more than
    $15,000,000; and
 
        TAX OPINION.  Clorox shall have received an opinion of its counsel, in
    form and substance reasonably satisfactory to Clorox on the basis of the
    facts, representations and assumptions set forth therein, to the effect that
    the Merger will be treated for federal income tax purposes as a
    reorganization qualifying under the provisions of Section 368(a) of the
    Code, and that each of Clorox, Merger Sub and First Brands will be a party
    to the reorganization within the meaning of Section 368(b) of the Code. In
    addition, in the event that Clorox or First Brands is unable to obtain the
    Tax Opinions, each of Clorox and First Brands is permitted under the Merger
    Agreement to waive the receipt of such Tax Opinions as a condition to such
    party's obligation to consummate the Merger. As of the date of this Proxy
    Statement/Prospectus, neither Clorox nor First Brands intends to waive the
    receipt of the Tax Opinions as a condition to such party's obligation to
    consummate the Merger. In the event of such a failure to obtain the Tax
    Opinions, and either Clorox or First Brands determines to waive such
    condition to the consummation of the Merger, First Brands will resolicit the
    votes of its stockholders to approve consummation of the Merger.
 
ADDITIONAL CONDITIONS TO THE OBLIGATIONS OF FIRST BRANDS
 
    The obligation of First Brands to effect the Merger is subject to additional
conditions which correspond to those set forth under "--Additional Conditions to
the Obligations of Clorox and Merger Sub," with the exception that First Brands'
obligations are not subject to the conditions captioned "Affiliate Agreements"
and "Advisor's Remuneration."
 
    On or prior to the Effective Time, to the extent legally allowed, each of
Clorox and First Brands, without the approval of the First Brands stockholders,
may waive compliance with any of the agreements or satisfaction of any of the
conditions contained in the Merger Agreement for its respective benefit. See
"--Amendment; Waiver."
 
TERMINATION
 
    TERMINATION GENERALLY.  The Merger Agreement may be terminated at any time
prior to the Effective Time and the Merger abandoned notwithstanding approval
thereof by the First Brands stockholders:
 
        (a) by mutual written consent duly authorized by the Clorox Board and
    the First Brands Board;
 
        (b) by either Clorox or First Brands if the Merger shall not have been
    consummated by June 30, 1999 (provided that this right to terminate the
    Merger Agreement will not be available to any party whose failure to fulfill
    any obligation under the Merger Agreement has been the cause of or resulted
    in the failure of the Merger to occur on or before such date);
 
                                       51
<PAGE>
        (c) by either Clorox or First Brands if a court of competent
    jurisdiction or governmental entity shall have issued a non-appealable final
    order or taken any other action, in each case having the effect of
    prohibiting the Merger, except if the party relying on such order has not
    complied with its obligations under the Merger Agreement with respect to
    using its reasonable best efforts to consummate the Merger and to use its
    best efforts to cause the Merger to qualify as a tax-free reorganization
    under the Code;
 
        (d) by Clorox or First Brands, if, at the First Brands stockholders'
    meeting (including any adjournment or postponement thereof), the requisite
    vote of the stockholders of First Brands shall not have been obtained;
 
        (e) by Clorox, if (1) the First Brands Board withdraws, modifies or
    changes its recommendation of the Merger Agreement or the Merger in a manner
    adverse to Clorox or has resolved to do any of the foregoing, (2) the First
    Brands Board shall have recommended to the stockholders of First Brands an
    Alternative Transaction or (3) a tender offer or exchange offer for 15% or
    more of the outstanding shares of First Brands Common Stock is commenced,
    and the First Brands Board recommends that the stockholders of First Brands
    tender their shares in such tender or exchange offer;
 
        (f) by First Brands, if its board of directors withdraws or modifies its
    recommendation of the Merger Agreement or the Merger following receipt of an
    unsolicited, bona fide proposal from a third party regarding an Alternative
    Transaction which the First Brands Board believes is a superior proposal, if
    after duly considering the advice of counsel, it determines it is necessary
    to do so in order to comply with its fiduciary duties, provided that it may
    not effect such termination unless and until it pays Clorox the Fee (as
    defined below); or
 
        (g) by Clorox or First Brands, upon a breach of any representation,
    warranty, covenant or agreement on the part of the other party set forth in
    the Merger Agreement such that such representation, warranty, covenant or
    agreement would not be true or correct or complied with in all material
    respects at the time of closing. However, if such breach is curable prior to
    June 30, 1999 by the breaching party, through the exercise of its reasonable
    best efforts, the non-breaching party may not terminate the Merger
    Agreement.
 
    EFFECT OF TERMINATION; TERMINATION FEE.  In the event of termination, the
Merger Agreement will be of no further effect and there will be no liability or
obligation on the part of any party to the Merger Agreement or their respective
affiliates, directors, officers or stockholders except (i) as provided in the
Merger Agreement with respect to payment of fees and survival of representations
and warranties and (ii) for a termination resulting from a willful breach by a
party to the Merger Agreement. Except for transaction expenses such as
attorneys' fees, printing and filing costs and the Fee (as defined below), (i)
all fees and expenses incurred in connection with the Merger Agreement and the
transactions contemplated thereby will be paid by the party incurring such
expenses, if the Merger is not consummated or (ii) if the Merger is consummated,
then the Surviving Corporation will pay all such fees and expenses; provided,
however, that Clorox and First Brands will share equally all fees and expenses,
other than attorney's fees, incurred in relation to the printing and filing of
this Proxy Statement/ Prospectus and the Registration Statement including any
preliminary materials related thereto.
 
    Pursuant to the Merger Agreement, First Brands will pay Clorox a fee of
$52,000,000 in cash (the "Fee"), upon the earlier to occur of (i) the
termination of the Merger Agreement by Clorox pursuant to the rights described
under part (e) of "--Termination Generally" or (ii) one day prior to the
termination of the Merger Agreement by First Brands pursuant to the rights
described under part (f) of "--Termination Generally."
 
                                       52
<PAGE>
AMENDMENT; WAIVER
 
    The Merger Agreement may be amended by the parties thereto by action taken
by or on behalf of their respective board of directors at any time prior to the
Effective Time; provided, however, that, after approval of the Merger by the
stockholders of First Brands, any subsequent amendment which by law requires
stockholder approval may only be made with such approval. The Merger Agreement
may not be amended except by an instrument in writing signed by the parties
thereto.
 
    At the Effective Time or any time prior thereto, to the extent legally
allowed, the parties to the Merger Agreement may (1) extend the time for the
performance of any of the obligations or other acts of the other parties
thereto, (2) waive any inaccuracies in the representations and warranties
contained in the Merger Agreement or in any document delivered pursuant thereto
and (3) waive compliance with any of the agreements or conditions contained in
the Merger Agreement. Any agreement on the part of a party thereto to any such
extension or waiver shall be valid only if set forth in an instrument in writing
signed on behalf of such party.
 
                       DESCRIPTION OF CLOROX COMMON STOCK
 
    Clorox is authorized to issue up to 375,000,000 shares of Clorox Common
Stock, par value $1.00 per share. Holders of shares of Clorox Common Stock are
entitled to one vote per share on all matters to be voted on by stockholders.
The holders of Clorox Common Stock are entitled to receive such dividends, if
any, as may be declared from time to time by the Clorox Board out of funds
legally available therefor. Upon liquidation or dissolution of Clorox, the
holders of Clorox Common Stock are entitled to share ratably in the distribution
of assets, subject to the rights of the holders of Clorox Preferred Stock (as
defined below), if any. Holders of Clorox Common Stock have no preemptive
rights, subscription rights or conversion rights. There are no redemption or
sinking fund provisions with respect to the Clorox Common Stock. As of December

    In addition, Clorox is authorized to issue 5,000,000 shares of preferred
stock, $1.00 par value per share (the "Clorox Preferred Stock"), in one or more
series as determined by the Clorox Board. No shares of Clorox Preferred Stock

and fix the rights and preferences of those shares, including the dividend
rights, dividend rates, conversion rights, exchange rights, voting rights, terms
of redemption, redemption price or prices, liquidation preferences, the number
of shares constituting any series and the designation of such series. The rights

                  COMPARISON OF RIGHTS OF CLOROX STOCKHOLDERS
                         AND FIRST BRANDS STOCKHOLDERS
 
    THE FOLLOWING IS A SUMMARY OF THE PRINCIPAL DIFFERENCES BETWEEN THE CURRENT
RIGHTS OF FIRST BRANDS STOCKHOLDERS AND THOSE OF CLOROX STOCKHOLDERS FOLLOWING
THE MERGER. IT IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE DGCL, THE
CERTIFICATE OF INCORPORATION OF CLOROX (THE "CLOROX CHARTER"), THE BYLAWS OF
CLOROX (THE "CLOROX BYLAWS"), THE CERTIFICATE OF INCORPORATION OF FIRST BRANDS
(THE "FIRST BRANDS CHARTER") AND THE BYLAWS OF FIRST BRANDS (THE "FIRST BRANDS
BYLAWS"). COPIES OF THE CLOROX CHARTER AND THE CLOROX BYLAWS ARE INCORPORATED BY
REFERENCE HEREIN AND WILL BE SENT TO HOLDERS OF SHARES OF FIRST BRANDS COMMON
STOCK UPON A REQUEST MADE TO CLOROX'S SECRETARY. SEE "WHERE YOU CAN FIND MORE
INFORMATION."
 
COMPARISON OF CURRENT FIRST BRANDS STOCKHOLDER RIGHTS AND RIGHTS OF CLOROX
  STOCKHOLDERS FOLLOWING THE MERGER
 
    Neither the Clorox Charter nor the Clorox Bylaws are being amended in
connection with the Merger. Accordingly, upon consummation of the Merger, the
rights of First Brands stockholders who become Clorox stockholders in the Merger
will be governed by the DGCL, and each of the Clorox Charter and the Clorox
Bylaws, as currently in effect.
 
    The rights of First Brands stockholders under the First Brands Charter and
the First Brands Bylaws prior to the Merger are substantially the same as the
rights of Clorox stockholders (including First Brands stockholders who become
Clorox stockholders as a result of the Merger) under the Clorox Charter and the
Clorox Bylaws, with the following principal exceptions:
 
    AUTHORIZED COMMON STOCK.  The authorized Common Stock of First Brands
consists of 120,000,000 shares, par value $0.01 per share, of which
approximately 39,135,000 shares were issued and outstanding as of December 15,
1998. In addition, First Brands has authorized 10,000,000 shares of preferred
stock, par value $1.00 per share, for issuance. No shares of First Brands
preferred stock are currently issued and outstanding. The authorized capital of
Clorox is set forth under "Description of Clorox Common Stock."
 
    BOARD OF DIRECTORS; NUMBER OF DIRECTORS.  The First Brands Charter provides
that the First Brands Board will have no less than 9 nor more than 15 members,
with the exact number to be determined by the First Brands Board. The First
Brands Board currently consists of 10 members. The Clorox Charter provides that
the Clorox Board will consist of no less than 9 members, with the exact number
to be determined by the Clorox Board. The Clorox Board currently consists of 11
members.
 
    TERM OF DIRECTORS.  Members of the First Brands Board are divided into three
classes, with each class serving a staggered three-year term. Members of the
Clorox Board are not divided into classes and serve for a term of one year.
 
    COMPOSITION OF THE BOARD/NOMINATION OF DIRECTORS.  Neither the First Brands
Charter nor the First Brands Bylaws provide for cumulative voting for election
of directors. Nominations of persons for election to the First Brands Board may
be made by or at the direction of the First Brands Board, or by First Brands
stockholders in accordance with the procedures set forth in the First Brands
Bylaws. Under the First Brands Charter, vacancies in the First Brands Board may
be filled by the affirmative vote of a majority of the directors then in office,
though less than a quorum, or by a sole remaining director. Any director elected
to fill a vacancy holds office until the next meeting of stockholders at which
the term of office of the class to which such director has been appointed
expires. Pursuant to the First Brands Charter, one or more members of the First
Brands Board may be removed only for cause (as defined in the First Brands
Charter) at a special meeting of stockholders called for that purpose, by vote
of the holders of a majority of the voting power of all of the shares of First
Brands entitled to vote for the election of directors.
 
                                       54
<PAGE>
    Neither the Clorox Charter nor the Clorox Bylaws provides for cumulative
voting for election of directors. Nominations of persons for election to the
Clorox Board may be made by or at the direction of the Clorox Board, or by
Clorox stockholders according to the procedures described in the Clorox Bylaws.
Under the Clorox Bylaws, vacancies in the Clorox Board may be filled by
resolution of a majority of the directors then in office, though less than a
quorum, or by a sole remaining director, and any director so appointed will hold
office until the next annual meeting of stockholders. The Clorox Charter and the
Clorox Bylaws do not contain provisions regarding the removal of directors, and
accordingly such matter would be governed by the DGCL. The DGCL provides that
directors may be removed (with or without cause) by vote of the holders of a
majority of shares entitled to vote at an election of directors.
 
    AMENDMENT OF CHARTER/BYLAWS.  Except as described below with respect to
supermajority voting requirements, any provision contained in the First Brands
Charter may be amended, altered, changed or repealed as prescribed pursuant to
the DGCL.
 
    The First Brands Bylaws may be amended by the affirmative vote of two-thirds
of the shares entitled to vote thereon or by a majority of the First Brands
Board, each without the consent of the other; except that revisions to the
provisions of the First Brands Bylaws relating to the holding and notice of
annual and special meetings of the First Brands stockholders, the nomination and
election of directors, and the amendment of the First Brands Bylaws, if made by
the First Brands Board, must be approved by a vote of not less than two-thirds
of the entire First Brands Board.
 
    Except as described below with respect to supermajority voting requirements,
any provision contained in the Clorox Charter may be amended, altered, changed
or repealed as prescribed by the DGCL.
 
    The Clorox Bylaws provide for their amendment by a majority of either the
Clorox Board or the shares entitled to vote thereon.
 
    SUPERMAJORITY VOTING REQUIREMENTS/SHAREHOLDER ACTION BY WRITTEN
CONSENT.  The First Brands Charter provides that First Brands may not merge with
any business entity, sell, exchange or dispose of all or substantially all its
assets or liquidate or dissolve without the affirmative vote of two-thirds of
the shares entitled to vote thereon. The First Brands Charter also provides that
the affirmative vote of two-thirds of the First Brands voting stock is required
to amend or repeal the provisions in the First Brands Charter governing the
election and removal of directors, and the affirmative vote of 80% of the First
Brands voting stock is required to amend or repeal the provisions governing the
classification and terms of members of the First Brands Board. The First Brands
Charter also provides that no action may be taken by the stockholders by written
consent in lieu of a meeting unless and until 80% of the First Brands Common
Stock is held by one person or entity.
 
    The Clorox Charter provides that any (i) merger of Clorox or any subsidiary
into or with an Interested Stockholder (generally, a 5% stockholder) or any
other corporation which after such merger would be an affiliate of such
Interested Stockholder, (ii) sale of or other disposition of assets to or with
any Interested Stockholder or any affiliate thereof with an aggregate fair
market value of more than 10% of the consolidated total assets of Clorox, (iii)
issuance of any securities of Clorox or any subsidiary to an Interested
Stockholder or any affiliate thereof the consideration for which has an
aggregate fair market value of more than 10% of the consolidated total assets of
Clorox, (iv) adoption of any plan or proposal for the liquidation of Clorox by
or on behalf of an Interested Stockholder or an affiliate thereof, or (v) any
reclassification or recapitalization of the securities of Clorox or any merger
or consolidation of Clorox with any of its subsidiaries or any other transaction
that has the effect, directly or indirectly, of increasing the proportionate
share of Clorox's equity securities owned by any Interested Stockholder will
require the affirmative vote of at least 80% of the voting stock outstanding,
unless the transaction is approved by a majority of the Disinterested Directors
(generally, a Clorox Board member who is unaffiliated with an Interested
Stockholder) or the consideration offered in the
 
                                       55
<PAGE>
transaction meets certain requirements as described in Article Six of the Clorox
Charter. The Clorox Charter further provides that the foregoing provisions may
only be modified upon the affirmative vote of 80% of the voting stock
outstanding. The Clorox Charter also provides that no action may be taken by the
Clorox stockholders by written consent.
 
    RIGHTS PLAN.  In March 1996, First Brands adopted a Rights Agreement (the
"Rights Plan") pursuant to which one preferred share purchase right was issued
for each outstanding share of First Brands Common Stock outstanding or issued on
or after April 1, 1996. Each right entitles the holder to purchase one
one-thousandth of a share of First Brands Junior Participating Preferred Stock,
Series A, at a price of $87.50 upon the occurrence of certain events. The rights
expire in April 2006, unless earlier redeemed by First Brands.
 
    The rights become exercisable upon the earlier to occur of (i) a person
having acquired, or obtained the right to acquire, beneficial ownership of 20%
or more of the First Brands Common Stock, and (ii) on the tenth business day
after the public announcement of the commencement of a tender offer or exchange
offer for First Brands Common Stock, if after acquiring the maximum number of
shares sought pursuant to such offer, the person making the offer would own 20%
or more of the outstanding shares of First Brands Common Stock. If First Brands
were to be acquired at any time after the rights become exercisable, the holder
of a purchase right would have the right to receive, upon exercise of the right,
that number of shares of common stock of the acquiring company or First Brands,
as the case may be, which would have a market value equal to two times the
exercise price of the right. The purchase rights are redeemable by the First
Brands Board at a price of $0.01 per right at any time within ten days after a
person has acquired 20% or more of the First Brands Common Stock. THE FIRST
BRANDS BOARD PASSED A RESOLUTION PRIOR TO SIGNING THE MERGER AGREEMENT MAKING
THE RIGHTS PLAN INAPPLICABLE TO CLOROX OR THE MERGER.
 
    The above summary of the Rights Plan is qualified in its entirety by
reference to the terms and conditions of the Rights Plan and the First Brands
Charter. See "Where You Can Find More Information."
 
    Clorox has not adopted a stockholders' rights plan.
 
    REDEMPTION RIGHTS.  Neither the First Brands Charter nor the Clorox Charter
contemplates the repurchase or redemption of shares of common stock, but either
action is allowed under the DGCL, and each company has repurchased its shares in
the past.
 
    INDEMNIFICATION.  Under the First Brands Charter and the First Brands
Bylaws, First Brands is required to indemnify, in the manner and to the full
extent permitted by law, any person made or threatened to be made a party to a
proceeding (whether civil, criminal or otherwise) by reason of the fact that
such person (or his estate) is or was a director or officer of First Brands or
by reason of the fact that such director or officer was serving in any other
capacity at the request of First Brands. However, a director will be liable to
the extent provided by applicable law (1) for any breach of the director's duty
of loyalty to First Brands or its stockholders, (2) for acts or omissions not in
good faith or which involve intentional misconduct or a knowing violation of the
law, (3) under Section 174 of the DGCL or (4) for any transaction from which the
director derived an improper personal benefit. First Brands may also, to the
full extent permitted by law, purchase and maintain insurance on behalf of any
of its directors, officers or agents and may advance the expenses of any current
or former director, officer employee or trustee in defending any action brought
against any of them. No person will be entitled to indemnification or to
advances with respect to any action brought by them against First Brands other
than an action to recover or enforce such person's right to indemnification or
advance.
 
    The Clorox Charter provides that Clorox is required to indemnify to the full
extent permitted by Delaware law any person made, or threatened to be made, a
party to an action or proceeding, whether criminal, civil, administrative or
investigative, by reason of the fact that the person, or the testator or
 
                                       56
<PAGE>
intestate of such person, is or was a director or officer of Clorox, or served
any business as a director or officer at the request of Clorox. Expenses
incurred by a director of Clorox in defending a civil or criminal action, suit
or proceeding by reason of the fact that such person was a director of Clorox
(and not in any other capacity, including if such person was serving at Clorox's
request as a director or officer of another enterprise or corporation) will be
paid by Clorox in advance of the final disposition of such action, suit or
proceeding upon receipt of an undertaking by or on behalf of such director to
repay such amount if it shall ultimately be determined that such person is not
entitled to be indemnified by Clorox as authorized by relevant sections of the
DGCL. Clorox will indemnify officers or directors in connection with a
proceeding initiated by them only if such proceeding was authorized by the
Clorox Board. Any person who is not paid pursuant to the foregoing
indemnification provisions 90 days after submitting a written claim to Clorox
may sue to recover such unpaid amounts and, if successful, will be entitled to
be paid the expense of prosecuting such claim (except for any such claims as
Clorox is not permitted by law to indemnify, although the burden of proving such
defense will be on Clorox). The Clorox Charter also provides that no director
will be liable to Clorox for a breach of fiduciary duty, except (1) for any
breach of the director's duty of loyalty to Clorox or its stockholders, (2) for
acts or omissions not in good faith or which involve intentional misconduct or a

                        PRO FORMA FINANCIAL INFORMATION
 
FINANCIAL STATEMENTS
 
    The following unaudited pro forma combined condensed financial statements
have been prepared to give effect to the Merger, using the pooling of interests
method of accounting.
 
    The unaudited pro forma combined condensed financial statements reflect
certain assumptions deemed probable by management regarding the Merger (for
example, the share information used in the unaudited pro forma information
approximates actual share information at the Effective Time). No adjustments to
the unaudited pro forma combined condensed financial information have been made
to account for different possible results in connection with the foregoing, as
management believes that the impact on such information by the varying outcomes,
individually or in the aggregate, would not be material.
 
    The unaudited pro forma combined condensed balance sheet as of September 30,
1998 gives effect to the Merger as if it had occurred on September 30, 1998, and
combines the unaudited consolidated balance sheet of Clorox and the unaudited
consolidated balance sheet of First Brands as of September 30, 1998. The
unaudited pro forma combined statements of income for all periods presented give
effect to the Merger as if it had occurred at the beginning of the periods
presented. For purposes of the unaudited pro forma combined condensed statements
of income for the periods presented, First Brands' consolidated statements of
income for the fiscal years ended June 30, 1996, 1997 and 1998 have been
combined with Clorox's consolidated statements of income for each of the fiscal
years ended June 30, 1996, 1997 and 1998, respectively. Additionally for
purposes of the pro forma combined condensed statements of income, First Brands'
consolidated statements of income for the three month periods ended September
30, 1997 and 1998 have been combined with Clorox's consolidated statements of
income for the three month periods ended September 30, 1997 and 1998,
respectively.
 
    Clorox and First Brands estimate they will incur combined aggregate direct
transaction costs of approximately $15.5 million associated with the Merger,
consisting of transaction fees for investment bankers, attorneys, accountants,
and other related costs. These nonrecurring transaction costs will be charged to
operations upon consummation of the Merger. It is expected that following the
Merger, the combined company will incur additional nonrecurring costs currently
estimated to be approximately $125 million, including non-cash charges estimated
at $30 million. No estimate for these charges has been reflected in the pro
forma combined condensed balance sheet or pro forma combined condensed
statements of income. There can be no assurance that the combined company will
not incur additional charges in excess of $125 million, to reflect costs
associated with the Merger or that management will be successful in its efforts
to integrate the operations of the two companies.
 
    The unaudited pro forma combined condensed financial information is
presented in this Proxy Statement/Prospectus for illustrative purposes only and
is not necessarily indicative of the financial position or results of operations
that would have actually been reported had the Merger occurred at the beginning
of the periods presented (or as of September 30, 1998, as the case may be), nor
is it necessarily indicative of the financial position or results of operations
of the merged company in the future. Such unaudited pro forma combined condensed
financial statements are based upon the respective historical consolidated
financial statements and notes thereto of Clorox and First Brands included
elsewhere in this Proxy Statement/Prospectus or incorporated herein by
reference, and do not incorporate, nor do they assume, any benefits from cost
savings or synergies that the combined company may realize after the Merger.

                          NOTES TO UNAUDITED PRO FORMA
 
                    COMBINED CONDENSED FINANCIAL STATEMENTS
 
(1) PRO FORMA BASIS OF PRESENTATION
 
    The unaudited pro forma combined condensed financial statements for the
years ended June 30, 1996, 1997 and 1998 reflect the combination of the
financial statements of Clorox and First Brands for those years. The unaudited
pro forma combined condensed statements of earnings for the three month periods
ended September 30, 1997 and 1998 reflect the combination of the statements of
earnings of Clorox and First Brands for those periods. No adjustments have been
made in these pro forma combined condensed financial statements to conform the
accounting policies of the combined company, as the nature and amounts of such
adjustments are deemed insignificant.
 
    These unaudited pro forma combined condensed financial statements reflect
the issuance of 13,833,000 shares of Clorox Common Stock in exchange for an
aggregate of 39,020,000 shares of First Brands Common Stock (outstanding as of
September 30, 1998) in connection with the Merger, based on an assumed Exchange
Ratio of 0.3545 (which assumes an average price for Clorox Common Stock of $110
per share during the prescribed measurement period) as set forth in the
following table:
 
<TABLE>
<S>                                                              <C>
Shares of First Brands Common Stock outstanding as of September
  30, 1998.....................................................   39,020,000
Exchange Ratio.................................................       0.3545
                                                                 -----------
Number of shares of Clorox Common Stock exchanged for First
  Brands Common Stock..........................................   13,833,000
Number of shares of Clorox Common Stock outstanding at
  September 30, 1998...........................................  103,525,000
                                                                 -----------
Number of shares of Clorox Common Stock outstanding at
  September 30, 1998 after giving effect to the Merger.........  117,358,000
                                                                 -----------
                                                                 -----------
</TABLE>
 
    The actual number of shares of Clorox Common Stock to be issued will be
determined at the Effective Time based on the number of shares of First Brands
Common Stock outstanding at that date and the Exchange Ratio. See "Risk
Factors--Adjustable Exchange Ratio."
 
(2) PRO FORMA COMBINED BALANCE SHEET
 
    (a) Clorox and First Brands estimate they will incur direct transaction
costs of approximately $15,500,000 associated with the Merger, consisting of
transaction fees for investment bankers, attorneys, accountants, and other
related costs. These nonrecurring transaction costs will be charged to
operations upon consummation of the Merger. These charges have been reflected in
the unaudited pro forma combined condensed balance sheet but have not been
included in the unaudited pro forma combined condensed statements of earnings.
 
    (b) Represents certain reclassifications to conform First Brands' balance
sheet classifications to Clorox's balance sheet classifications at September 30,
1998.
 
    (c) It is expected that, following the Merger, the combined company will
incur additional nonrecurring costs currently estimated to be approximately
$125,000,000, including non-cash charges estimated at $30,000,000, in connection
with the Merger. No estimate for these charges has been reflected in the pro
forma combined condensed balance sheet or combined condensed statements of
earnings. There can be no assurance that the combined company will not incur
additional charges in excess of $125,000,000 to reflect costs associated with
the Merger, or that management will be successful in its efforts to integrate
the operations of the two companies.

FIRST BRANDS BOARD AND COMMITTEES
 
    There were five regular and two telephonic meetings of the First Brands
Board during fiscal year 1998. All of the incumbent directors attended at least
78% of the total number of meetings of the First Brands Board and committees on
which they served. Directors who are employees of First Brands do not receive
any compensation for service as directors. Mr. Dudley, who retired from First
Brands on September 1, 1994, and relinquished the title of Chairman on January
1, 1997, received a fee of $100,000 for consulting services from July 1, 1997
through December 31, 1997. Each non-employee director is currently paid an
annual retainer of $20,000 and fees of $1,000 for attendance at each First
Brands Board meeting or committee meeting not held in conjunction with a board
meeting. First Brands Board members are paid $500 for attendance at each
telephonic meeting, or telephonic committee meeting not held in conjunction with
a board meeting. Directors are also reimbursed for reasonable expenses incurred
in attending board and committee meetings of First Brands. In addition, under
the Director's Plan adopted at the 1995 First Brands annual meeting of
stockholders, non-employee directors receive 2,000 non-qualified stock options
on the first Friday following First Brands' annual meeting of stockholders. The
options vest on the second anniversary of the grant and have an exercise price
equal to the average of the high and low prices on the date of grant.

            COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION
 
    The Compensation Committee of the First Brands Board consists of three
non-employee directors who make decisions pertaining to executive compensation
and benefits. The Committee uses the services of an outside compensation
consultant to assist in making objective decisions based on data from consumer
products companies of similar size, some of which are in the peer group of
companies included in the stock performance graph.
 
COMPENSATION PHILOSOPHY
 
    First Brands' executive compensation program has three objectives:
 
    1.  To provide compensation that rewards executives for meeting and
       exceeding internal performance goals and standards.
 
    2.  To maintain a compensation program that attracts and retains high
       quality executives.
 
    3.  To create a link between the interests of First Brands' stockholders,
       First Brands' financial performance and the total compensation
       opportunities for its executive officers.
 
    The executive compensation program consists of base salary, an annual cash
incentive plan, long-term stock option incentive plans, a non-qualified deferred
compensation plan, an executive life insurance plan, and qualified and
non-qualified retirement plans.
 
    First Brands maintains a benefit program that is competitive with other
consumer products companies of similar size. The program includes qualified
retirement, savings and disability programs as well as medical, dental and
business travel insurance programs.
 
    Base salaries are targeted slightly below the 50th percentile of competitive
salaries for executives of consumer products companies of similar size. Salary
ranges are established using published surveys and other external data.
Variation in compensation between individuals is based on position value,
experience level and performance against pre-established objectives. Individual
increases are typically given at twelve month intervals, and the amount is based
on the individual's performance and place in the salary range. Prior to
approving individual increases, the Compensation Committee reviews each senior
executive's performance against previously established performance goals.
 
    First Brands' Annual Incentive Plan provides for an annual cash award based
on attainment of operating income goals, and the awards are targeted at slightly
above the 50th percentile for executives of consumer products companies of
similar size. The plan triggers if a pre-approved threshold is achieved.
Individual awards are determined by total corporate, business unit and
individual performance levels. The performance level of the business unit is
measured on an unweighted basis by market share and operating income. Individual
performance goals are established for each senior executive at
 
                                       65
<PAGE>
the commencement of each year. The Compensation Committee approves the total
dollar pool available and the amount awarded to each senior executive
participant. In respect of the named executives in the Summary Compensation
Table on page 68, the Compensation Committee will also assess First Brands'
relative financial performance against peer group consumer products companies
considering such measures as earnings per share growth, sales growth,
improvement in return on equity and acquisition success.
 
    The Option Plans were established in 1989, 1994 and 1998. All option shares
available under the 1989 Long Term Incentive Plan have been granted. The 1989
plan provides for non-qualified stock options, Long-term Stock Appreciation
Rights ("LSAR's") and restricted stock. LSAR's are exercisable only in change of
control situations. The 1994 Performance Stock Option and Incentive Plan
provides for non-qualified stock options, LSAR's and restricted stock. Options
may have an exercise price of either 100% of the fair market value of the
underlying shares of common stock ("Market Priced Options") or more than 100% of
such fair market value ("Premium Priced Options"). Of the Market Priced Options,
a portion may vest as of specific dates and a portion may be subject to
performance vesting. At the time of the grant, a "trigger stock price" or other
performance criteria upon which the vesting of performance options will be based
may be established. These options will be exercisable at the earlier of the date
that the market price exceeds the trigger stock price or the ninth anniversary
of the grant. The 1998 Performance Stock Option and Incentive Plan provides for
non-qualified stock options, LSAR's and performance stock units (for
international management). There were no options granted during fiscal year
1998. No restricted stock has been granted under the 1989 or the 1994 plan, and
there is no provision for restricted stock in the 1998 plan. The Compensation
Committee approves grants of a sufficient number and type of stock options to
retain executives based on its review of surveys of long-term incentive and
long-term capital accumulation plans available to similar positions at other
consumer products companies of similar size.
 
    In addition to the qualified retirement plans, officers of First Brands also
participate in a non-qualified Retirement Plan that alleviates the impact of tax
or legal restrictions imposed upon the qualified plan when total annual
compensation is used in calculating pension benefits.
 
    First Brands has established its Deferral Plan for senior executives. This
plan permits deferral of a portion of base salary and/or annual incentive awards
to a later date, normally until after retirement. Interest on deferred
compensation is based on seven-year U.S. Treasury Bond yields plus a margin
which is intended to approximate the margin First Brands would incur if it were
issuing a senior unsecured bond with a seven-year maturity. If the participant
defers salary or bonus for seven or more years or until death, disability or
retirement, the interest on the deferred amount for the entire period will be
the Treasury Bond yield, plus the margin, plus 3%.
 
    The Compensation Committee endorses the position that stock ownership by
management provides linkage in aligning management's and stockholders' interest
in enhancing stockholder value although the Committee does not set target
ownership levels for executive equity holdings. During fiscal year 1995,
stockholders approved an amendment to the Annual Incentive Plan which permits
certain members of senior management to elect to receive all or a portion of
their annual incentive award in First Brands Common Stock instead of cash. Those
who elect stock instead of cash receive a premium of 25% in stock, thereby
encouraging management to increase stock ownership. The stock acquired under the
Annual Incentive Plan is restricted in its transferability or sale for a period
of two years from the date of issuance.
 
    Section 162(m) of the Code, enacted in 1993, limits the tax deduction that
corporations may take with respect to the compensation of certain executive
officers, unless the compensation is "performance based" as defined in the Code.
The Committee believes that all compensation received by the executive officers
is performance based, and in any event, the deductibility limits in the Code
have not been reached. There is no loss of deduction for fiscal year 1998.

RELATIONSHIP OF CORPORATE PERFORMANCE TO EXECUTIVE COMPENSATION
 
    First Brands has two types of executive compensation incentive plans, the
Annual Incentive Plan and the Option Plans (both previously described), which
reward executives based on the performance of First Brands.
 
    The Annual Incentive Plan provides compensation based on the attainment of
operating income objectives which are contained in the annual business plan. For
the named executives in the Summary Compensation Table, First Brands' financial
performance relative to a peer group of companies is also considered in order to
validate incentive compensation in comparison with these companies. The annual
business plan is developed by First Brands' management and approved by the First
Brands Board at the beginning of each fiscal year. The financial measures used
to validate incentive awards are approved by the Compensation Committee at the
beginning of each fiscal year.
 
    The Option Plans use stock price appreciation as the incentive to reward
executives over the long term. Compensation gained as a result of this program
has a direct relationship to the gain achieved by investors in First Brands'
stock.
 
1998 FISCAL YEAR COMPENSATION OF CHIEF EXECUTIVE OFFICER
 
    Mr. Stephenson earned $465,000 in base salary during fiscal year 1998 and
received an annual incentive award of $180,000 for his overall performance for
the year. The Compensation Committee determined that these amounts were
justified when considering First Brands' financial performance for the fiscal
year as well as Mr. Stephenson's personal performance based upon return on
equity, sales growth, acquisition success, market share, operating income,
earnings per share growth and overall management effectiveness. The Compensation
Committee also considered Mr. Stephenson's compensation as compared to chief
executive officers of the peer group of consumer products companies that First
Brands traditionally monitors. Mr. Stephenson's total cash compensation (base
salary and annual incentive) for fiscal year 1998 was slightly lower than the
preceding fiscal year.

RETIREMENT PLAN
 
    First Brands currently maintains the First Brands' Retirement Program Plan,
a non-contributory defined benefit Retirement Plan covering 78% of all U.S.
employees, including those of its subsidiaries. The officers listed in the
foregoing Summary Compensation Table are covered by this Retirement Plan.
Outside the United States, certain of First Brands' subsidiaries have retirement
programs that are generally administered by trustees or insurance companies.
 
    Under this Retirement Plan, the monthly amount of an employee's retirement
benefit upon retirement at age 65 is the greater of (a) 1.2% of average monthly
compensation received during the three-year period preceding retirement, or 1.2%
of average monthly compensation received during the three best calendar years in
the final ten calendar years preceding retirement, if the latter average would
result in a higher pension benefit, multiplied by the number of years of
credited service, plus $12 or (b) 1.5% of the average monthly compensation
computed as in (a) above, multiplied by the number of years of credited service,
less a percentage, based on service and not exceeding 50%, of the projected
primary Social Security benefit or such maximum percentage as is allowed under
the Code. In January 1995, First Brands announced a change in this formula
beginning January 2000, to a defined benefit based on years of credited service
and career average compensation. Effective January 1, 2000 the formula for the
retirement program is changed as follows: the total benefit will equal the sum
of (a) the pension benefit for each individual as of December 31, 1999 using the
present formulas and (b) 1.5% of eligible annual earnings for each year.
 
    An employee who is (i) age 62 or over with ten or more years of credited
service or (ii) whose age and years of credited service add up to 85, may
voluntarily retire earlier than age 65 with a retirement benefit, unreduced
because of early retirement. Employees may retire as early as age 50 with ten
years of credited service but will receive an actuarially reduced pension
benefit.
 
    The amounts contributed by First Brands to this Retirement Plan are
calculated on a group basis that is actuarially determined. No specific amount
is set aside by First Brands for any individual officer or employee under this
Retirement Plan. The amounts shown in the following table are the estimated
annual retirement benefits payable at age 65 for the respective average annual
remuneration levels and years of service credit indicated. Actual benefits will
not exceed limits permitted under the Code and applicable regulations. Amounts
shown are computed based upon straight life annuity amounts and are
 
                                       69
<PAGE>
reduced by 1.5% of the employee's primary Social Security benefit for each year
of the employee's credited service up to a maximum deduction of 50% of such
Social Security benefit. Annual retirement benefits are based on average
earnings.
 
    For federal income tax purposes the amount of benefits that can be paid from
the qualified plan is restricted. First Brands maintains a nonqualified
Retirement Plan, the effect of which is to award retirement benefits to all
employees on a uniform basis. The nonqualified Retirement Plan is unfunded.
 
    First Brands also maintains a savings plan as part of its long term
retirement/savings program to which it contributes to the account of each
eligible employee who chooses to participate. Effective January 1995, First
Brands contributes 50% of each employee's basic 401(k) contributions, up to 6%
of regular earnings. Any regular employee of First Brands or its subsidiaries is
eligible to participate. In fiscal year 1996, First Brands instituted a profit
sharing contribution based on First Brands' operating performance. Profit
sharing will be contributed in shares of First Brands common stock, allocated to
separate employee 401(k) accounts based on First Brands service credit.
 
    As of June 30, 1998, the credited years of service (credited service is
combined from First Brands and Union Carbide Corporation) for the individuals
named in the Summary Compensation Table were as follows: William V. Stephenson,
34 years; Thomas H. Rowland, 24 years; Donald A. DeSantis, 12 years; Einar M.
Rod, 2 years; and Patrick J. O'Brien, 13 years.

SEVERANCE AGREEMENTS
 
    First Brands has also entered into Severance Agreements with certain
executive officers generally providing severance benefits if the employee is
terminated for reasons other than "cause" within two years after a "change in
control." The severance benefits include cash payments equal to two years salary
and bonus, except for William V. Stephenson, who would receive payments equal to
three years salary and bonus, and certain other employee and retirement
benefits. Provision for a tax gross-up payment is also included to cover excise
taxes, if any, on payments paid under these agreements. See "The
Merger--Interests of Certain Persons in the Merger."

                                       OF
                           REORGANIZATION AND MERGER
 
    THIS AGREEMENT AND PLAN OF REORGANIZATION AND MERGER, dated as of October
18, 1998 (this "AGREEMENT"), among THE CLOROX COMPANY, a Delaware corporation
("PARENT"), PENNANT, INC., a Delaware corporation and a direct wholly owned
subsidiary of Parent ("MERGER SUB"), and FIRST BRANDS CORPORATION, a Delaware
corporation (the "COMPANY").
 
                                  WITNESSETH:
 
    WHEREAS, the Boards of Directors of Parent, Merger Sub and the Company have
each determined that it is advisable and in the best interests of their
respective stockholders for Parent to enter into a strategic business
combination with the Company upon the terms and subject to the conditions set
forth herein;
 
    WHEREAS, in furtherance of such combination, the Boards of Directors of
Parent, Merger Sub and the Company have each approved the Merger (the "MERGER")
of Merger Sub with and into the Company in accordance with the applicable
provisions of the Delaware General Corporation Law ("DGCL"), and upon the terms
and subject to the conditions set forth herein;
 
    WHEREAS, Parent, Merger Sub and the Company intend that the Merger qualify
as a reorganization under Section 368(a) of the Internal Revenue Code of 1986,
as amended (the "CODE"), and that, by approving resolutions authorizing this
Agreement, this Agreement be adopted as a plan of reorganization under Section
368 of the Code;
 
    WHEREAS, pursuant to the Merger, each outstanding share of common stock of
the Company, par value $0.01 per share (the "COMPANY COMMON STOCK" and each
share, a "SHARE") shall be exchanged for the right to receive the Merger
Consideration (as defined in Section 1.07(b)), upon the terms and subject to the
conditions set forth herein; and
 
    WHEREAS, for financial accounting purposes, Parent, Merger Sub and the
Company intend that the Merger be accounted for as a pooling of interests
transaction.
 
    NOW, THEREFORE, in consideration of the foregoing and the mutual covenants
and agreements herein contained, and intending to be legally bound hereby,
Parent, Merger Sub and the Company hereby agree as follows:
 
                                   ARTICLE I
                                   THE MERGER
 
    SECTION 1.01.  THE MERGER.
 
    (a) At the Effective Time (as defined in Section 1.02 hereof), and subject
to and upon the terms and conditions of this Agreement and in accordance with
the DGCL, Merger Sub shall be merged with and into the Company, the separate
corporate existence of Merger Sub shall cease upon the filing of a certificate
of merger with the Secretary of State of the State of Delaware pursuant to the
DGCL, and the Company shall continue as the surviving corporation being the
successor to all the property, rights, powers, privileges, liabilities and
obligations of both Merger Sub and the Company. The Company as the surviving
corporation after the Merger is hereinafter sometimes referred to as the
"SURVIVING COMPANY."
 
    (b) The closing of the Merger (the "CLOSING") shall take place at a time and
on a date to be specified by the parties, which shall be no later than the
second business day after satisfaction or waiver of the conditions set forth in
Article VI, unless another time or date is agreed to in writing by the parties
hereto. The Closing will be held at the offices of Morrison & Foerster LLP
("MOFO"), 425
 
                                      A-1
<PAGE>
Market Street, San Francisco, California 94105, unless another place is agreed
to in writing by the parties hereto.
 
    SECTION 1.02.  EFFECTIVE TIME.  As promptly as practicable after the
satisfaction or waiver of the conditions set forth in Article VI, but in no
event later than three days thereafter, the parties hereto shall cause the
Merger to be consummated by filing all necessary documentation (the "MERGER
DOCUMENTS"), together with any required related certificates, with the Secretary
of State of the State of Delaware, in such form as required by, and executed in
accordance with the relevant provisions of, the DGCL (the time of such filing
being the "EFFECTIVE TIME").
 
    SECTION 1.03.  EFFECT OF THE MERGER.  The Merger shall have the effects set
forth in Section 259 of the DGCL.
 
    SECTION 1.04.  CERTIFICATE OF INCORPORATION AND BY-LAWS.  Unless otherwise
determined by Parent prior to the Effective Time, at the Effective Time the
certificate of incorporation and by-laws of Merger Sub, as in effect immediately
prior to the Effective Time shall be the certificate of incorporation and
by-laws of the Surviving Company (the "CERTIFICATE OF INCORPORATION" and
"BY-LAWS") until thereafter changed or amended as provided therein or by the
DGCL; provided, however, that Article I of the certificate of incorporation of
the Surviving Company shall be amended to read as follows: "The name of the
company is First Brands Corporation."
 
    SECTION 1.05.  DIRECTORS AND OFFICERS.  The directors of Merger Sub
immediately prior to the Effective Time shall be the initial directors of the
Surviving Company, each to hold office in accordance with the Certificate of
Incorporation and By-laws, and the officers of Merger Sub immediately prior to
the Effective Time shall be the initial officers of the Surviving Company, in
each case until their respective successors are duly elected or appointed and
qualified.
 
    SECTION 1.06.  MERGER CONSIDERATION; CONVERSION AND CANCELLATION OF
SECURITIES.  At the Effective Time, by virtue of the Merger and without any
action on the part of Parent, Merger Sub, the Company or the holders of any of
the Shares:
 
        (a)  CONVERSION OF SECURITIES.  Each Share issued and outstanding
    immediately prior to the Effective Time (excluding any Shares to be canceled
    pursuant to Section 1.06(b)) shall be converted, subject to Section 1.06(f),
    into the right to receive that number of validly issued, fully paid and
    nonassessable shares of common stock, $1.00 par value per share (the "PARENT
    COMMON STOCK") equal to the Exchange Ratio (as defined below).
 
        The exchange ratio for the Merger (the "Exchange Ratio") shall be
    calculated as follows:
 
            (i) If the average of the closing prices of the Parent Common Stock
       on the New York Stock Exchange ("NYSE") Composite Transaction Tape (as
       reported in The Wall Street Journal or, if not reported therein, any
       other authoritative source) during the ten trading days preceding the
       fifth trading day prior to the Effective Time (carried to the fourth
       decimal place) (the "PARENT AVERAGE SHARE PRICE") is less than or equal
       to $80.00, the Exchange Ratio will be 0.4875;
 
            (ii) If the Parent Average Share Price is greater than $80.00, but
       less than or equal to $115.00, the Exchange Ratio will be the quotient of
       (A) $39.00 divided by (B) the Parent Average Share Price, rounded to the
       nearest one-one thousandth of a share;
 
           (iii) If the Parent Average Share Price is greater than $115.00, the
       Exchange Ratio will be 0.3391.
 
        (b)  CANCELLATION.  Each Share owned by the Company, Parent, Merger Sub
    or any direct or indirect wholly owned subsidiary of the Company or Parent
    immediately prior to the Effective
 
                                      A-2

    Time shall, by virtue of the Merger and without any action on the part of
    the holder thereof, be canceled and retired without payment of any
    consideration therefor and cease to exist.
 
        (c)  ASSUMPTION OF STOCK OPTIONS.
 
            (i) At the Effective Time, each outstanding option to purchase (a
       "STOCK OPTION") Company Common Stock granted under the Company's 1989
       Long Term Incentive Plan, the Company's 1994 Performance Stock Option and
       Incentive Plan, the Company's 1998 Performance Stock Option and Incentive
       Plan, and the Company's Non-Employee Directors Stock Option Plan
       (collectively, the "COMPANY STOCK OPTION PLANS"), whether vested or
       unvested, shall be deemed assumed by Parent and deemed to constitute an
       option to acquire, on the same terms and conditions as were applicable
       under such Stock Option prior to the Effective Time, the number (rounded
       down to the nearest whole number) of shares of Parent Common Stock as the
       holder of such Stock Option would have been entitled to receive pursuant
       to the Merger had such holder exercised such option in full immediately
       prior to the Effective Time (not taking into account whether or not such
       option was in fact exercisable), at a price per share rounded up to the
       nearest whole cent equal to (x) the aggregate exercise price for Company
       Common Stock otherwise purchasable pursuant to such Stock Option divided
       by (y) the number of shares of Parent Common Stock deemed purchasable
       pursuant to such Stock Option; PROVIDED, HOWEVER, that the vesting
       schedule of the assumed options (including any accelerated vesting of
       such options due to the transactions contemplated by this Agreement)
       shall continue to be determined by reference to the applicable Company
       Stock Option Plan.
 
            (ii) As soon as practicable after the Effective Time, Parent shall
       deliver to each holder of an outstanding Stock Option an appropriate
       notice setting forth such holder's rights pursuant thereto and such Stock
       Option shall continue in effect on the same terms and conditions
       (including any applicable anti-dilution provisions, and subject to the
       adjustments required by this Section 1.06(c) after giving effect to the
       Merger). Parent shall comply with the terms of all such Stock Options and
       ensure, to the extent required by, and subject to the provisions of, the
       applicable Company Stock Option Plan that any Stock Options which
       qualified for special tax treatment prior to the Effective Time continue
       to so qualify after the Effective Time. Parent shall take all corporate
       action necessary to reserve for issuance a sufficient number of shares of
       Parent Common Stock for delivery pursuant to the terms set forth in this
       Section 1.06(c).
 
           (iii) At the Effective Time, each outstanding award (including
       restricted stock, stock equivalents and stock units, but excluding Stock
       Options) ("COMPANY AWARD") under any employee incentive or benefit plans,
       programs or arrangements and non-employee director plans presently
       maintained by the Company which provide for grants of equity-based awards
       shall be amended or converted into a similar instrument of Parent, in
       each case with such adjustments to the terms of such Company Awards as
       are appropriate to preserve the value inherent in such Company Awards
       with no detrimental effects on the holders thereof. The other terms of
       each Company Award, and the plans or agreements under which they were
       issued, shall continue to apply in accordance with their terms, including
       any provisions for acceleration. Parent shall take all corporate action
       necessary to reserve for issuance a sufficient number of shares of Parent
       Common Stock for delivery pursuant to the terms set forth in this Section
       1.06(c)(iii).
 
        (d)  COMMON STOCK OF MERGER SUB.  Each share of the common stock of
    Merger Sub issued and outstanding immediately prior to the Effective Time
    shall be converted into and exchanged for a validly issued, fully paid and
    nonassessable share of common stock of the Surviving Company. Each share
    certificate of Merger Sub evidencing ownership of any such shares shall
    evidence, from and after the Effective Time, ownership of such shares of the
    Surviving Company.
 
                                      A-3
<PAGE>
        (e)  LONG TERM STOCK APPRECIATION RIGHTS.  Subject to the consent of the
    holders thereof, each limited stock appreciation right to purchase shares of
    Company Common Stock under the Company Stock Option Plans ("LSAR'S") shall
    be cancelled and the tandem Stock Option shall be assumed pursuant to
    Section 1.06(c).
 
        (f)  ADJUSTMENTS TO EXCHANGE RATIO.  The Exchange Ratio shall be
    adjusted to reflect fully the effect of any share split, reverse split,
    share dividend (including any dividend or distribution of securities
    convertible into Parent Common Stock or Company Common Stock),
    reorganization, recapitalization or other like change with respect to Parent
    Common Stock or Company Common Stock occurring after the date hereof and
    prior to the Effective Time.
 
        (g)  FRACTIONAL SHARES.  No fraction of a share of Parent Common Stock
    will be issued, but in lieu thereof each holder of Company Common Stock who
    would otherwise be entitled to a fraction of a share of Parent Common Stock
    (after aggregating all fractional shares of Parent Common Stock to be
    received by such holder) shall receive from Parent an amount of cash
    (rounded up to the nearest whole cent), without interest, equal to the
    product of (i) such fraction, multiplied by (ii) closing price of the Parent
    Common Stock on the NYSE Composite Transaction Tape on the last trading day
    immediately prior to the Effective Time (as reported in the Wall Street
    Journal or, if not reported therein, any other authoritative source).
 
    SECTION 1.07.  EXCHANGE OF CERTIFICATES.
 
    (a)  EXCHANGE AGENT.  Parent shall supply, or shall cause to be supplied, to
or for the account of a bank or trust company designated by Parent (the
"EXCHANGE AGENT"), in trust for the benefit of the holders of Company Common
Stock, for exchange in accordance with this Section 1.07, through the Exchange
Agent, certificates or other evidence of title evidencing the shares of Parent
Common Stock issuable pursuant to Section 1.06 in exchange for outstanding
Shares. Parent shall make available to the Exchange Agent from time to time as
needed, cash sufficient to pay cash in lieu of fractional shares.
 
    (b)  EXCHANGE PROCEDURES.  As soon as reasonably practicable after the
Effective Time, Parent will instruct the Exchange Agent to mail to each holder
of record of a certificate or certificates which immediately prior to the
Effective Time evidenced outstanding Shares (the "CERTIFICATES") (i) a letter of
transmittal (which shall specify that delivery shall be effected, and risk of
loss and title to the Certificates shall pass, only upon proper delivery of the
Certificates to the Exchange Agent and shall be in such form and have such other
provisions as Parent may reasonably specify) and (ii) instructions to effect the
surrender of the Certificates in exchange for the certificates evidencing shares
of Parent Common Stock and, in lieu of any fractional shares thereof, cash. Upon
surrender of a Certificate to the Exchange Agent for cancellation together with
such letter of transmittal, duly executed, and such other customary documents as
may be required pursuant to such instructions, the holder of such Certificate
shall be entitled to receive in exchange therefor (A) certificates evidencing
that number of whole shares of Parent Common Stock which such holder has the
right to receive in accordance with the Exchange Ratio in respect of the Shares
formerly evidenced by such Certificate, (B) any dividends or other distributions
with respect to Shares to which such holder was entitled to receive prior to the
Effective Time, and (C) cash in lieu of fractional shares of Parent Common Stock
to which such holder is entitled pursuant to Section 1.06(g) (the shares of
Parent Common Stock, dividends, distributions and cash described in clauses
(A)-(C) delivered for each share being, collectively, the "MERGER
CONSIDERATION"), and the Certificate so surrendered shall forthwith be canceled.
In the event of a transfer of ownership of Shares which is not registered in the
transfer records of the Company as of the Effective Time, Parent Common Stock
and cash may be issued and paid in accordance with this Article I to a
transferee if the Certificate evidencing such Shares is presented to the
Exchange Agent, accompanied by all documents required to evidence and effect
such transfer pursuant to this Section 1.07(b) and by evidence that any
applicable stock/share transfer taxes have been paid. Until so surrendered, each
outstanding Certificate that, prior to the Effective Time, represented Shares
will be deemed from and
 
                                      A-4
<PAGE>
after the Effective Time, for all corporate purposes other than the payment of
dividends, to evidence the ownership of the number of full shares of Parent
Common Stock into which such Shares shall have been so converted and the right
to receive an amount in cash in lieu of the issuance of any fractional shares in
accordance with Section 1.06.
 
    (c)  DISTRIBUTIONS WITH RESPECT TO UNEXCHANGED PARENT COMMON STOCK.  No
dividends or other distributions declared or made after the Effective Time with
respect to shares of Parent Common Stock with a record date after the Effective
Time shall be paid to the holder of any unsurrendered Certificate with respect
to shares of Parent Common Stock they are entitled to receive until the holder
of such Certificate shall surrender such Certificate. Subject to applicable law,
following surrender of any such Certificate, there shall be paid to the record
holder of the certificates representing whole shares of Parent Common Stock
issued in exchange therefor, without interest, at the time of such surrender,
the amount of dividends or other distributions with a record date after the
Effective Time theretofore paid with respect to such whole shares of Parent
Common Stock and cash in lieu of any fractional share of Parent Common Stock
pursuant to Section 1.06(g) above.
 
    (d)  TRANSFERS OF OWNERSHIP.  If any certificate for shares of Parent Common
Stock is to be issued in a name other than that in which the Certificate
surrendered in exchange therefor is registered, it will be a condition of the
issuance thereof that the Certificate so surrendered will be properly endorsed
and otherwise in proper form for transfer and that the person requesting such
exchange will have paid to Parent or any agent designated by it any transfer or
other taxes required by reason of the issuance of a certificate for shares of
Parent Common Stock in any name other than that of the registered holder of the
Certificate surrendered, or established to the satisfaction of Parent or any
agent designated by it that such tax has been paid or is not payable.
 
    (e)  NO LIABILITY.  Neither Parent, Merger Sub nor the Company shall be
liable to any holder of Shares for any Merger Consideration (or dividends or
distributions with respect thereto) delivered to a public official pursuant to
any applicable abandoned property, escheat or similar law.
 
    (f)  WITHHOLDING RIGHTS.  Parent or the Exchange Agent shall be entitled to
deduct and withhold from the Merger Consideration otherwise payable pursuant to
this Agreement to any holder of Shares such amounts as Parent or the Exchange
Agent is required to deduct and withhold with respect to the making of such
payment under the Code, or any provision of state, local or foreign tax law. To
the extent that amounts are so withheld by Parent or the Exchange Agent, such
withheld amounts shall be treated for all purposes of this Agreement as having
been paid to the holder of the Shares in respect of which such deduction and
withholding was made by Parent or the Exchange Agent.
 
    SECTION 1.08.  STOCK TRANSFER BOOKS.  At the Effective Time, the stock
transfer books of the Company shall be closed, the Merger Consideration
delivered upon the surrender for exchange of Shares in accordance with the terms
hereof shall be deemed to have been issued in full satisfaction of all rights
pertaining to such Shares, and there shall be no further registration of
transfers on the records of the Surviving Company of Shares which were
outstanding immediately prior to the Effective Time. If, after the Effective
Time, Certificates are presented to the Surviving Company for any reason, they
shall be canceled and exchanged as provided in this Article I.
 
    SECTION 1.09.  LOST, STOLEN OR DESTROYED CERTIFICATE.  In the event any
Certificates shall have been lost, stolen or destroyed, the Exchange Agent shall
issue in exchange for such lost, stolen or destroyed Certificates, upon the
making of an affidavit of that fact by the holder thereof, such shares of Parent
Common Stock and cash as may be required pursuant to Section 1.06; PROVIDED,
HOWEVER, that Parent may, in its discretion and as a condition precedent to the
issuance thereof, require the owner of such lost, stolen or destroyed
Certificates to deliver a bond in such sum as it may reasonably direct as
indemnity against any claim that may be made against Parent or the Exchange
Agent with respect to the Certificates alleged to have been lost, stolen or
destroyed.

<PAGE>
    SECTION 1.10.  TAX AND ACCOUNTING CONSEQUENCES.  It is intended by the
parties hereto that the Merger shall (i) constitute a reorganization within the
meaning of Section 368(a) of the Code and (ii) qualify for accounting treatment
as a pooling of interests under United States generally accepted accounting
principles ("U.S. GAAP"). The parties hereto hereby adopt this Agreement as a
"plan of reorganization" within the meaning of Section 368 of the Code.
 
    SECTION 1.11.  MATERIAL ADVERSE EFFECT.  When used in connection with the
Company or any of its subsidiaries, or Parent or any of its respective
subsidiaries, as the case may be, the term "MATERIAL ADVERSE EFFECT" means any
change or effect that, individually or in the aggregate, is materially adverse
to the business, assets (including intangible assets), financial condition or
results of operations of the Company and its subsidiaries ("COMPANY MATERIAL
ADVERSE EFFECT") or of Parent and its subsidiaries ("PARENT MATERIAL ADVERSE
EFFECT"), respectively, in each case taken as a whole, but other than those
adverse effects occurring as a result of general economic or financial
conditions which generally affect other persons who participate or are engaged
in lines of business in which the Company or Parent, as the case may be,
participate or are engaged.
 
                                   ARTICLE II
                 REPRESENTATIONS AND WARRANTIES OF THE COMPANY
 
    The Company hereby represents and warrants to Parent and Merger Sub that:
 
    SECTION 2.01.  ORGANIZATION AND QUALIFICATION; SUBSIDIARIES.  The Company is
a corporation and each of its subsidiaries is an entity duly organized, validly
existing and in good standing under the laws of the jurisdiction of its
formation, has the requisite corporate (or other similar) power and authority
and is in possession of all franchises, grants, authorizations, licenses,
permits, easements, consents, certificates, approvals and orders ("APPROVALS")
necessary to own, lease and operate the properties it purports to own, lease or
operate and to carry on its business as it is now being conducted, except where
the failure to have such power, authority and Approvals would not, individually
or in the aggregate, have a Company Material Adverse Effect. The Company and
each subsidiary is duly qualified or licensed as a foreign entity to do
business, and is in good standing, in each jurisdiction where the character of
its properties owned, leased or operated by it or the nature of its activities
makes such qualification or licensing necessary, except for such failures to be
so duly qualified or licensed and in good standing that would not, either
individually or in the aggregate, have a Company Material Adverse Effect.
 
    SECTION 2.02.  CAPITALIZATION.  The authorized capital stock of the Company
consists of 120,000,000 shares of Company Common Stock and 10,000,000 shares of
Preferred Stock, par value $1.00 per share ("COMPANY PREFERRED STOCK"). As of
October 15, 1998, (i) 39,045,100 shares of Company Common Stock were issued and
outstanding, all of which are validly issued, fully paid and nonassessable, (ii)
4,513,460 shares of Company Common Stock were held by the Company in its
treasury, (iii) no shares of Company Common Stock were held by any subsidiary,
(iv) no shares of Company Preferred Stock were issued and outstanding and (v)
3,091,170 shares of Company Common Stock were reserved for future issuance
pursuant to outstanding employee stock options granted pursuant to the Company's
Stock Option Plans. Except as set forth in Section 2.02 of the written
disclosure schedule previously provided by Company to Parent (the "COMPANY
DISCLOSURE SCHEDULE"), no shares of Company Common Stock have been issued
between June 30, 1998 and the date hereof, other than pursuant to the Company
Employee Plans. Except as set forth in Section 2.02 of the Company Disclosure
Schedule, there are no options, warrants or other rights, agreements,
arrangements or commitments of any character relating to the issued or unissued
shares (or other equity interests) of the Company or of any subsidiary or
obligating the Company or any subsidiary to issue or sell any shares of, or
other equity interests in, the Company or any subsidiary. All shares of Company
Common Stock subject to issuance as aforesaid, upon issuance on the terms and
conditions specified in the instruments pursuant to which they are
 
                                      A-6
<PAGE>
issuable, shall be duly authorized, validly issued, fully paid and
nonassessable. There are no obligations, contingent or otherwise, of the Company
or of any subsidiary to repurchase, redeem or otherwise acquire any shares of
Company Common Stock or the shares of any subsidiary. Except as set forth in
Section 2.02 of the Company Disclosure Schedule or as will not have a Company
Material Adverse Effect, all of the outstanding equity interests of each
subsidiary are duly authorized, validly issued, fully paid and nonassessable,
and all such equity interests are owned by the Company free and clear of all
security interests, liens, claims, pledges, agreements, limitations in voting
rights, charges or other encumbrances of any nature whatsoever (collectively,
"LIENS"), other than Liens for taxes not yet due and payable and Liens being
negotiated in good faith and for which proper reserves exist.
 
    SECTION 2.03.  AUTHORITY RELATIVE TO THIS AGREEMENT.  The Company has all
necessary corporate power and authority to execute and deliver this Agreement
and subject to obtaining any necessary stockholder approval of this Agreement,
to perform its obligations hereunder and to consummate the transactions
contemplated hereby. The execution and delivery of this Agreement by the Company
and the consummation by the Company of the transactions contemplated hereby have
been duly and validly authorized by all necessary corporate action and no other
corporate proceedings on the part of the Company are necessary to authorize this
Agreement or to consummate the transactions so contemplated (other than the
approval and adoption of the Merger by at least two-thirds of the holders of the
outstanding Shares entitled to vote in accordance with the Company's certificate
of incorporation and by-laws). The board of directors of the Company has
determined that it is advisable and in the best interest of the Company's
stockholders for the Company to enter into a strategic business combination with
Parent upon the terms and subject to the conditions of this Agreement, and has
recommended that the Company's stockholders approve and adopt this Agreement and
the transactions contemplated hereby. This Agreement has been duly and validly
executed and delivered by the Company and, assuming the due authorization,
execution and delivery by Parent and Merger Sub, as applicable, constitutes a
legal, valid and binding obligation of the Company enforceable against the
Company in accordance with its terms.
 
    SECTION 2.04.  SEC FILINGS; FINANCIAL STATEMENTS.
 
    (a) The Company has filed all forms, reports, exhibits and other documents
required to be filed with the Securities and Exchange Commission ("SEC") since
June 30, 1998 and has made available to Parent (i) its Quarterly Report on Form
10-Q for the period ended March 31, 1998 and its Annual Reports on Form 10-K for
the period ended June 30, 1997 and June 30, 1998, respectively, (ii) all proxy
statements relating to the Company's meetings of stockholders (whether annual or
special) held since June 30, 1997, (iii) all other reports or registration
statements (other than reports on Forms 3, 4 or 5 filed on behalf of affiliates
of the Company) filed by the Company with the SEC since June 30, 1998, and (iv)
all amendments and supplements to all such reports and registration statements
filed by the Company with the SEC (collectively, the "COMPANY SEC REPORTS"). The
Company SEC Reports (i) were prepared in accordance with the requirements of the
Securities Act of 1933, as amended (the "SECURITIES ACT") or the Securities
Exchange Act of 1934, as amended, and the SEC's rules thereunder (collectively,
the "EXCHANGE ACT"), as the case may be, and (ii) did not at the time they were
filed (or if amended or superseded by a filing prior to the date of this
Agreement, then on the date of such filing) contain any untrue statement of a
material fact or omit to state a material fact required to be stated therein or
necessary in order to make the statements therein, in light of the circumstances
under which they were made, not misleading. No subsidiary is required to file
any forms, reports or other documents with the SEC.
 
    (b) Each of the consolidated financial statements (including, in each case,
any related notes thereto) contained in the Company SEC Reports was prepared in
accordance with U.S. GAAP applied on a consistent basis throughout the periods
involved (except as may be indicated in the notes thereto) and each fairly
presents the consolidated financial position of the Company and its subsidiaries
as at the respective dates thereof and the consolidated results of its
operations and cash flows for the
 
                                      A-7
<PAGE>
periods indicated, except that the unaudited interim financial statements were
or are subject to normal and recurring year-end adjustments which were not or
are not expected to be material in amount.
 
    (c) The Company has heretofore furnished to Parent a complete and correct
copy of any amendments or modifications, which have not yet been filed with the
SEC but which are required to be filed, to agreements, documents or other
instruments which previously had been filed by the Company with the SEC pursuant
to the Securities Act or the Exchange Act.
 
    SECTION 2.05.  ABSENCE OF CERTAIN CHANGES OR EVENTS.  Except as set forth in
Section 2.05 of the Company Disclosure Schedule or the Company SEC Reports,
since June 30, 1998, the Company has conducted its business in the ordinary
course and there has not occurred: (i) any Company Material Adverse Effect; (ii)
any change by the Company in its accounting methods, principles or practices;
(iii) any revaluation of any of the Company's or any subsidiary's assets,
including, without limitation, writing down the value of inventory or writing
off notes or accounts receivable other than in the ordinary course of business;
(iv) any sale, pledge, disposition of or encumbrance upon a material amount of
property of the Company or of any subsidiary, except in the ordinary course of
business and consistent with past practice; or (v) any material Tax (as defined
below) election inconsistent with past practices or the settlement or compromise
of any material Tax liability.
 
    SECTION 2.06.  NO UNDISCLOSED LIABILITIES.  Except as is set forth in
Section 2.06 of the Company Disclosure Schedule or in the Company SEC Reports,
neither the Company nor any subsidiary has any liabilities (absolute, accrued,
contingent or otherwise) which are, in the aggregate, material to the business,
operations or financial condition of the Company and its subsidiaries taken as a
whole, except liabilities (a) adequately provided for in the Company's balance
sheet (including any related notes thereto) as of June 30, 1998 (the "1998
COMPANY BALANCE SHEET"); (b) incurred in the ordinary course of business and not
required under U.S. GAAP to be reflected on such balance sheet, (c) incurred
since June 30, 1998 in the ordinary course of business and consistent with past
practice or (d) incurred in connection with the transactions contemplated by
this Agreement to Lehman Brothers Inc., Skadden, Arps, Slate, Meagher & Flom LLP
("SKADDEN") and KPMG Peat Marwick, LLP ("KPMG").
 
    SECTION 2.07.  NO VIOLATION.  Except as set forth in Section 2.07 of the
Company Disclosure Schedule, the execution and delivery of this Agreement by the
Company does not, and the performance of this Agreement by the Company will not,
and the consummation by the Company of the transactions contemplated hereby will
not, (i) conflict with or violate the certificate of incorporation or by-laws of
the Company, (ii) conflict with or violate any federal, foreign, state or
provincial law, rule, regulation, order, judgment or decree (collectively,
"LAWS") applicable to the Company or any subsidiary or by which any of their
respective properties are bound or affected, or (iii) result in any breach of or
constitute a default (or an event that with notice or lapse of time or both
would become a default) under, or impair the Company's or any subsidiary's
rights or alter the rights or obligations of any third party under, or give to
others any rights of termination, amendment, acceleration or cancellation of,
any material contract, or result in the creation of a Lien on any of the
properties or assets of the Company or any subsidiary pursuant to, any note,
bond, mortgage, indenture, contract, agreement, lease, license, permit,
franchise or other instrument or obligation to which the Company or any
subsidiary is a party or by which the Company or any subsidiary or any of their
respective properties are bound or affected, except in the case of clauses (ii)
and (iii) for any such conflicts, violations, breaches, defaults or other
occurrences that would not, individually or in the aggregate, have a Company
Material Adverse Effect.
 
    SECTION 2.08.  ABSENCE OF LITIGATION.  Except as set forth in Section 2.08
of the Company Disclosure Schedule or the Company SEC Reports, (i) there are no
claims, actions, suits, proceedings or investigations pending or, to the
knowledge of the Company, threatened against the Company or against any
subsidiary and (ii) there is no judgment, decree, injunction, rule or order
outstanding against the Company or its subsidiaries other than, in each case,
those that the outcome of which,
 
                                      A-8
<PAGE>
individually or in the aggregate, would not have a Company Material Adverse
Effect or a material adverse effect on the Company's ability to consummate the
Merger.
 
    SECTION 2.09.  EMPLOYEE BENEFIT PLANS; EMPLOYMENT AGREEMENTS.
 
    (a) For purposes of this Section 2.09: "ERISA" means the Employee Retirement
Income Security Act of 1974, as amended; "COMPANY ERISA AFFILIATE" means any
trade or business (whether or not incorporated) which is a member of a
controlled group including the Company or which is under common control with the
Company or any subsidiary of the Company; and "COMPANY EMPLOYEE PLANS" means all
bonus, stock option, stock purchase, incentive, deferred compensation,
supplemental retirement, severance and other fringe or employee benefit plans,
programs or arrangements, and any current or former employment or executive
compensation or severance agreements, written or otherwise, for the benefit of,
or relating to, any employee of the Company, as well as each such plan with
respect to which the Company or a Company ERISA Affiliate could incur liability
under applicable law (if such plan has been or were terminated), and excluding
agreements with former employees under which the Company has no remaining
monetary obligations.
 
    (b) Except as set forth in Section 2.09(b) of the Company Disclosure
Schedule, none of the Company Employee Plans promises or provides retiree
medical or other retiree welfare benefits to any person other than coverage
mandated by applicable law or benefits, the full cost of which is borne by the
retiree.
 
    (c) Except as set forth in Section 2.09(c) of the Company Disclosure
Schedule or as would not have a Company Material Adverse Effect: (i) the Company
and its subsidiaries have complied with ERISA, the Code and all laws and
regulations applicable to the Company Employee Plans and each Company Employee
Plan has been maintained and administered in compliance with its terms; and (ii)
each Company Employee Plan intended to qualify under Section 401(a) of the Code
and each trust intended to qualify under Section 501(a) of the Code is the
subject of a favorable determination letter from the IRS, and nothing has
occurred which may reasonably be expected to impair such determination.
 
    (d) Neither the Company nor its subsidiaries have incurred any liability
under Title IV of ERISA (other than liability for premiums to the Pension
Benefit Guaranty Corporation arising in the ordinary course). No Company
Employee Plan has incurred an "accumulated funding deficiency" (within the
meaning of Section 302 of ERISA or Section 412 of the Code) whether or not
waived. To the knowledge of the Company, there are not any facts or
circumstances that would materially change the funded status of any Company
Employee Plan that is a "defined benefit" plan (as defined in Section 3(35) of
ERISA) since the date of the most recent actuarial report for such plan. No
Company Employee Plan is a "multiemployer plan" within the meaning of Section
3(37) of ERISA.
 
    (e) Except as set forth in Section 2.09(e) of the Company Disclosure
Schedule, with respect to each of the Company Employee Plans that is subject to
Title IV of ERISA, the present value of accrued benefits under each such plan
did not, as of its latest valuation date, exceed the then current value of the
aggregate assets of such plans allocable to the payment of such benefits.
 
    SECTION 2.10.  LABOR MATTERS.  Except as set forth in Section 2.09 of the
Company Disclosure Schedule, (i) there are no controversies pending or, to the
knowledge of the Company or any subsidiary, threatened, between the Company or
any subsidiary and any of their respective employees, other than such pending or
threatened controversies which would not, individually or in the aggregate, have
a Company Material Adverse Effect; and (ii) neither the Company nor any
subsidiary has any knowledge of any strikes, slowdowns, work stoppages,
lockouts, or threats thereof, by or with respect to any employees of the Company
or of any subsidiary, except as have not, individually or in the aggregate, had
a Company Material Adverse Effect.

                                  ARTICLE III
            REPRESENTATIONS AND WARRANTIES OF PARENT AND MERGER SUB
 
    Parent and Merger Sub hereby represent and warrant to the Company that:
 
    SECTION 3.01.  ORGANIZATION AND QUALIFICATION; SUBSIDIARIES.
 
    (a) Parent is a corporation and each of its subsidiaries is an entity duly
organized, validly existing and in good standing under the laws of the
jurisdiction of its formation and has the requisite corporate (or other similar)
power and authority and is in possession of all Approvals necessary to own,
lease and operate the properties it purports to own, lease or operate and to
carry on its business as it is now being conducted, except where the failure to
have such power, authority and Approvals would not, individually or in the
aggregate, have a Parent Material Adverse Effect. Parent and each of its
subsidiaries is duly qualified or licensed as a foreign entity to do business,
and is in good standing, in each jurisdiction where the character of its
properties owned, leased or operated by it or the nature of its activities makes
such qualification or licensing necessary, except for such failures to be so
duly qualified or licensed and in good standing that would not, either
individually or in the aggregate, have a Parent Material Adverse Effect.
 
    SECTION 3.02.  CAPITALIZATION.
 
    (a) As of June 30, 1998, the authorized Common Stock of Parent consisted of
(i) 375,000,000 shares of Parent Common Stock of which: (x) 103,544,000 (rounded
to the nearest thousand) shares were issued and outstanding, (y) 7,300,000
(rounded to the nearest thousand) shares were held in its treasury, (z)
5,141,000 (rounded to the nearest thousand) shares were reserved for issuance
pursuant to outstanding options under Parent's stock option plans ("PARENT'S
STOCK OPTION PLANS"); and (ii) 5,000,000 shares of Preferred Stock, ("PARENT
PREFERRED STOCK"), no shares of which are issued and outstanding. No shares of
Parent Common Stock have been issued between June 30, 1998 and the date hereof,
except for shares issued upon exercise of options outstanding under Parent's
Stock Option Plans. The authorized common stock of Merger Sub consists of 100
shares of common stock, all of which, as of the date hereof, are issued and
outstanding. All of the outstanding shares of Parent's and Merger Sub's
respective common stock have been duly authorized and validly issued and are
fully paid and nonassessable. Except for options outstanding under Parent's
Stock Option Plans and as described in the Parent SEC Reports, there are no
options, warrants or other rights, agreements, arrangements or commitments of
any character relating to the issued or unissued common stock of Parent or any
of its subsidiaries or obligating Parent or any of its subsidiaries to issue or
sell any shares of common stock of, or other equity interests in Parent, or any
shares of common stock of its subsidiaries. All shares of Parent Common Stock
subject to issuance as aforesaid, upon issuance on the terms and conditions
specified in the instruments pursuant to which they are issuable, shall be duly
authorized, validly issued, fully paid and nonassessable. Except as described in
the Parent SEC Reports (as defined below), there are no obligations, contingent
or otherwise, of Parent or any of its subsidiaries to repurchase, redeem or
otherwise acquire any shares of Parent Common Stock or the Common Stock of any
subsidiary. Except as will not have a Parent Material Adverse Effect, all of the
outstanding shares of common stock (or other equity interests) of each of
Parent's subsidiaries is duly authorized, validly issued, fully paid and
nonassessable and all such shares are owned by Parent or another subsidiary free
and clear of all Liens other than Liens for taxes not yet due and payable and
Liens being negotiated in good faith and for which proper reserves exist.
 
                                      A-13
<PAGE>
    (b) The shares of Parent Common Stock to be issued pursuant to the Merger
will be duly authorized, validly issued, fully paid and nonassessable and shall
be available for trading on the NYSE.
 
    SECTION 3.03.  AUTHORITY RELATIVE TO THIS AGREEMENT.  Each of Parent and
Merger Sub has all necessary corporate power and authority to execute and
deliver this Agreement and, subject to obtaining any necessary stockholder
approval of this Agreement by Merger Sub, to perform its obligations hereunder
and to consummate the transactions contemplated hereby. The execution and
delivery of this Agreement by Parent and Merger Sub and the consummation by
Parent and Merger Sub of the transactions contemplated hereby have been duly and
validly authorized by all necessary corporate action on the part of Parent and
Merger Sub, and no other corporate proceedings on the part of Parent or Merger
Sub are necessary to authorize this Agreement or to consummate the transactions
so contemplated (other than the approval by Parent as sole stockholder of Merger
Sub). The board of directors of Parent has determined that it is advisable and
in the best interest of Parent's stockholders for Parent to enter into a
strategic business combination with the Company upon the terms and subject to
the conditions of this Agreement. This Agreement has been duly and validly
executed and delivered by Parent and Merger Sub and, assuming the due
authorization, execution and delivery by the Company, constitutes a legal, valid
and binding obligation of Parent and Merger Sub enforceable against each in
accordance with its terms.
 
    SECTION 3.04.  SEC FILINGS; FINANCIAL STATEMENTS.
 
    (a) Parent has filed all forms, reports, exhibits and other documents
required to be filed with the SEC since June 30, 1998 and has heretofore
delivered to the Company, in the form filed with the SEC, (i) its Annual Reports
on Form 10-K for the fiscal year ended June 30, 1997 and June 30, 1998, (ii) all
proxy statements relating to Parent's meetings of stockholders (whether annual
or special) held since June 30, 1997, (iii) all other reports or registration
statements (other than Reports on Form 3, 4 or 5 filed on behalf of affiliates
of the Parent) filed by Parent with the SEC since June 30, 1998 and (iv) all
amendments and supplements to all such reports and registration statements filed
by Parent with the SEC (collectively, the "PARENT SEC REPORTS"). The Parent SEC
Reports (i) were prepared in accordance with the requirements of the Securities
Act or the Exchange Act, as the case may be, and (ii) did not at the time they
were filed (or if amended or superseded by a filing prior to the date of this
Agreement, then on the date of such filing) contain any untrue statement of a
material fact or omit to state a material fact required to be stated therein or
necessary in order to make the statements therein, in the light of the
circumstances under which they were made, not misleading. None of Parent's
subsidiaries is required to file any forms, reports or other documents with the
SEC.
 
    (b) Each of the consolidated financial statements (including, in each case,
any related notes thereto) contained in the Parent SEC Reports has been prepared
in accordance with generally accepted accounting principles applied on a
consistent basis throughout the periods involved (except as may be indicated in
the notes thereto) and each fairly presents the consolidated financial position
of Parent and its subsidiaries as of the respective dates thereof and the
consolidated results of its operations and cash flows for the periods indicated,
except that the unaudited interim financial statements were or are subject to
normal and recurring year-end adjustments which were not or are not expected to
be material in amount.
 
    (c) Parent has heretofore furnished to the Company a complete and correct
copy of any amendments or modifications, which have not yet been filed with the
SEC but which are required to be filed, to agreements, documents or other
instruments which previously had been filed by Parent with the SEC pursuant to
the Securities Act or the Exchange Act.
 
    SECTION 3.05.  ABSENCE OF CERTAIN CHANGES OR EVENTS.  Since June 30, 1998,
Parent has conducted its business in the ordinary course and there has not
occurred: (i) any Parent Material Adverse Effect; (ii) any change by Parent in

of any of its assets, including without limitation, writing down the value of
inventory or writing
 
                                      A-14
<PAGE>
off notes or accounts receivable other than in the ordinary course of business;
or (iv) any sale, pledge, disposition or encumbrance upon a material amount of
property of Parent or of any subsidiary, except in the ordinary course of
business and consistent with past practice.
 
    SECTION 3.06.  NO UNDISCLOSED LIABILITIES.  Except as is set forth in the
Parent SEC Reports, neither the Parent nor any of its subsidiaries has any
liabilities (absolute, accrued, contingent or otherwise) which are, in the
aggregate, material to the business, operations or financial condition of the
Parent and its subsidiaries taken as a whole, except liabilities (a) adequately
provided for in the Parent's balance sheet (including any related notes thereto)
as of June 30, 1998, (b) incurred in the ordinary course of business and not
required under U.S. GAAP to be reflected on such balance sheet, (c) incurred
since June 30, 1998 in the ordinary course of business and consistent with past
practice, or (d) incurred in connection with the transactions contemplated by
this Agreement to J.P. Morgan Securities, Inc. ("JPM"), MoFo, and Deloitte &
Touche LLP ("D&T").
 
    SECTION 3.07.  ABSENCE OF LITIGATION.  Except as set forth in the Parent SEC
Reports, (i) there are no claims, actions, suits, proceedings or investigations
pending or, to the knowledge of the Parent, threatened against Parent against
any subsidiary and (ii) there is no judgment, decree, injunction, rule or order
outstanding against Parent or its subsidiaries, other than, in each case those
that the outcome of which, individually or in the aggregate, would not have a
Parent Material Adverse Effect.
 
    SECTION 3.08.  NO VIOLATION.  The execution and delivery of this Agreement
by Parent and Merger Sub does not, and the performance of this Agreement by
Parent and Merger Sub will not, and the consummation by Parent and Merger Sub of
the transactions contemplated hereby will not, (i) conflict with or violate the
certificate of incorporation or by-laws of Parent or Merger Sub, (ii) conflict
with or violate any Laws applicable to Parent or any subsidiary or by which any
of their respective properties are bound or affected, or (iii) result in any
breach of or constitute a default (or an event that with notice or lapse of time
or both would become a default) under, or impair Parent's or any subsidiary's
rights or alter the rights or obligations of any third party under, or give to
others any rights of termination, amendment, acceleration or cancellation of,
any material contract, or result in the creation of a lien or encumbrance on any
of the properties or assets of Parent or any subsidiary pursuant to, any note,
bond, mortgage, indenture, contract, agreement, lease, license, permit,
franchise or other instrument or obligation to which Parent or any subsidiary is
a party or by which Parent or any subsidiary or any of their respective
properties are bound or affected, except in the case of clauses (ii) and (iii)
for any such conflicts, violations, breaches, defaults or other occurrences that
would not, individually or in the aggregate, have a Parent Material Adverse
Effect.
 
    SECTION 3.09.  EMPLOYEE BENEFIT PLANS.
 
    (a) For purposes of this Section 3.09: "PARENT ERISA AFFILIATE" means any
trade or business (whether or not incorporated) which is a member of a
controlled group including Parent or which is under common control with Parent
or any subsidiary of Parent; and "PARENT EMPLOYEE PLANS" means all bonus, stock
option, stock purchase, incentive, deferred compensation, supplemental
retirement, severance and other similar fringe or employee benefit plans,
programs or arrangements, and any current or former employment or executive
compensation or severance agreements, written or otherwise, for the benefit of,
or relating to, any employee of Parent, as well as each such plan with respect
to which Parent or a Company ERISA Affiliate could incur liability under
applicable law (if such plan has been or were terminated), and excluding
agreements with former employees under which Parent has no remaining monetary
obligations.
 
    (b) Except as disclosed in the Parent SEC Reports, none of the Parent
Employee Plans promises or provides retiree medical or other retiree welfare
benefits to any person other than coverage mandated by applicable law or
benefits, the full cost of which is borne by the retiree.
 
                                      A-15
<PAGE>
    (c) Except as would not have a Parent Material Adverse Effect: (i) Parent
and its subsidiaries have complied with ERISA, the Code and all laws and
regulations applicable to Parent Employee Plans and each Parent Employee Plan
has been maintained and administered in compliance with its terms; and (ii) each
Parent Company Employee Plan intended to qualify under Section 401(a) of the
Code and each trust intended to qualify under Section 501(a) of the Code is the
subject of a favorable determination letter from the IRS, and nothing has
occurred which may reasonably be expected to impair such determination.
 
    (d) Neither Parent nor its subsidiaries have incurred any liability under
Title IV of ERISA (other than liability for premiums to the Pension Benefit
Guaranty Corporation arising in the ordinary course). No Company Employee Plan
has incurred an "accumulated funding deficiency" (within the meaning of Section
302 of ERISA or Section 412 of the Code) whether or not waived. To the knowledge
of Parent, there are not any facts or circumstances that would materially change
the funded status of any Parent Employee Plan that is a "defined benefit" plan
(as defined in Section 3(35) of ERISA) since the date of the most recent
actuarial report for such plan. No Parent Employee Plan is a "multiemployer
plan" within the meaning of Section 3(37) of ERISA.
 
    (e) With respect to each of the Parent Employee Plans that is subject to
Title IV of ERISA, the present value of accrued benefits under each such plan
did not, as of its latest valuation date, exceed the then current value of the
aggregate assets of such plans allocable to the payment of such benefits.
 
    SECTION 3.10.  LABOR MATTERS.  There are no controversies pending or, to the
knowledge of the Parent or any subsidiary, threatened, between the Parent or any
subsidiary and any of their respective employees other than such pending or
threatened controversies which would not, individually or in the aggregate, have
a Parent Material Adverse Effect. Neither the Parent nor any subsidiary has any
knowledge of any strikes, slowdowns, work stoppages, lockouts, or threats
thereof, by or with respect to any employees of the Parent or of any subsidiary,
except as have not, individually or in the aggregate, had a Parent Material
Adverse Effect.
 
    SECTION 3.11.  REGISTRATION STATEMENT; JOINT PROXY
STATEMENT/PROSPECTUS.  Subject to the accuracy of the representations of the
Company in Section 2.11, the Registration Statement shall not, at the time the
Registration Statement (including any amendments or supplements thereto) is
declared effective by the SEC, contain any untrue statement of a material fact
or omit to state any material fact required to be stated therein or necessary in
order to make the statements included therein, in light of the circumstances
under which they were made, not misleading. The information supplied by Parent
for inclusion in the Joint Proxy Statement/Prospectus will not, on the date the
Joint Proxy Statement/Prospectus is first mailed to stockholders (or at the time
of any subsequent amendment or supplement), at the time of the Company
Stockholders' Meeting and at the Effective Time: (i) contain any statement
which, at such time and in light of the circumstances under which it shall be
made, is false or misleading with respect to any material fact; (ii) omit to
state any material fact necessary in order to make the statements therein not
false or misleading; or (iii) omit to state any material fact necessary to
correct any statement in any earlier communication with respect to the
solicitation of proxies for the Company Stockholders' Meeting which has become
false or misleading. If at any time prior to the Effective Time any event
relating to Parent or any of its respective affiliates, officers or directors
should be discovered by Parent which should be set forth in an amendment to the
Registration Statement or a supplement to the Joint Proxy Statement/Prospectus,
Parent shall promptly inform Company. The Registration Statement and Joint Proxy
Statement/Prospectus shall comply in all material respects as to form and
substance with the requirements of the Securities Act, the Exchange Act and the
rules and regulations thereunder.
 
    SECTION 3.12.  TAXES.
 
    (a) Parent and each subsidiary have timely filed all United States federal
income Tax Returns and all other material Tax Returns required to be filed by
them. Such returns and reports are correct and
 
                                      A-16
<PAGE>
complete in all material respects, or requests for extensions to file such
returns have been granted and have not expired, except to the extent such
failures to file, to be current and complete, or to have such extensions granted
and that remain in effect, individually or in the aggregate, would not have a
Parent Material Adverse Effect. Parent and each subsidiary have timely paid or
made adequate provision on their books for the payment of all Taxes shown to be
due on such returns. Except as set forth in Section 3.12(a) of the disclosure
schedule previously delivered by Parent to the Company (the "PARENT DISCLOSURE
SCHEDULE"), none of Parent or any of its subsidiaries is a party to, is bound
by, or has any obligation under, any tax sharing agreement, tax indemnification
agreement or similar contract or arrangement. Parent has complied in all
material respects with the requirements of Section 6038 of the Code with respect
to its foreign subsidiaries.
 
    (b) No deficiencies for any Taxes have been proposed, asserted or assessed
against Parent or any of its subsidiaries for which adequate reserves are not
maintained, except for deficiencies that, individually or in the aggregate would
not have a Parent Material Adverse Effect. Except as set forth in Section
3.12(b) of the Parent Disclosure Schedule, neither the Parent nor any subsidiary
has given or been requested to give waivers or extensions of any statute of
limitations relating to the payment of Taxes for which Parent or any subsidiary
may be liable.
 
    SECTION 3.13.  ENVIRONMENTAL MATTERS.
 
    (a) Each of the Parent and its subsidiaries has obtained all Environmental
Permits, except for such failures to have Environmental Permits which,
individually or in the aggregate, are not reasonably expected to have a Parent
Material Adverse Effect. Each of such Environmental Permits is in full force and
effect and each of the Parent and its subsidiaries is in compliance with the
terms and conditions of all such Environmental Permits and with any applicable
Environmental Law, except for such failures to be in compliance which,
individually or in the aggregate, are not reasonably expected to have a Parent

affiliates, agents, or other representatives (including without limitation any
investment banker, attorney or accountant retained by it or any of its
subsidiaries) to not, initiate, solicit or encourage (including by way of
furnishing information or assistance), or take any other action to facilitate,
any inquiries or the making of any proposal to effect an Alternative Transaction
(as defined in Section 7.03(c)), or enter into discussions or negotiate with any
person or entity regarding an Alternative Transaction, or authorize any of the
officers, directors, employees or agents of the Company or of any subsidiary or
any investment banker, financial advisor, attorney, accountant or other
representative retained by the Company or any subsidiary to take any such
action; provided, however, that nothing contained in this subsection (a) shall
prohibit the board of directors of the Company from (i) furnishing information
to, or entering into discussions or negotiations with, any persons or entity in
connection with an unsolicited bona-fide proposal by such person or entity
relating to an Alternative Transaction if, and only to the extent that (A) the
board of directors of the Company determines in good faith after consultation
with Skadden, that the fiduciary duties of the board of directors under Delaware
law require consideration of the Alternative Transaction and (B) prior to
furnishing such information to, or entering into discussions or negotiations
with, such person or entity the Company requires such person or entity to enter
into a confidentiality agreement with the Company in customary form (with terms
no more favorable to such person or entity than the terms of the confidentiality
agreement between Parent and the Company), (ii) withdrawing or modifying its
recommendation referred to in Section 5.01 following receipt of an unsolicited,
bona-fide proposal from a third party regarding an Alternative Transaction which
is a Superior Proposal (as defined below), if after duly considering the advice
of Skadden, the board of directors of the Company determines in good faith that
it is necessary to do so in order to comply with its fiduciary duties to
stockholders imposed by Delaware law or (iii) complying with Rule 14e-2
promulgated under the Exchange Act with regard to an Alternative Transaction.
 
    "SUPERIOR PROPOSAL" as used herein is defined as a bona fide proposal for an
Alternative Transaction made by a third party on terms and conditions which the
board of directors of the Company determines in its good faith judgment to be
more favorable than those contained in this Agreement and for which financing,
to the extent required, is then committed.
 
                                      A-20
<PAGE>
    (b) Unless the board of directors of the Company determines in good faith
after consultation with Skadden that its fiduciary duties under Delaware law
require that it not do so, the Company will communicate to Parent the terms of
an Alternative Transaction which is a Superior Proposal.
 
    (c) The Company shall immediately cease and cause to be terminated any
existing discussions or negotiations with any parties (other than Parent and
Merger Sub) conducted heretofore with respect to any of the foregoing. The
Company agrees not to release any third party from any confidentiality or
standstill agreement to which the Company is a party (other than any release or
termination of any such agreement which may occur by the terms thereof).
 
    (d) The Company shall ensure that the officers, directors and employees of
the Company and of each subsidiary and any investment banker or other advisor or
representative retained by the Company are aware of the restrictions described
in this Section 4.02.
 
    (e) Nothing in this Section 4.02 shall (i) permit the Company to terminate
this Agreement or (ii) permit the Company to enter into any written agreement
with respect to an Alternative Transaction during the term of this Agreement (it
being agreed that during the term of this Agreement the Company shall not enter
into any written agreement with any person that provides for, or in any way
facilitates, an Alternative Transaction, other than a confidentiality agreement
in the form referred to above), it being understood that Section 7.01(f) sets
forth the rights of the Company to terminate this Agreement in the circumstances
specified in Section 4.02(a)(ii) above.

of all information required to be contained therein, the Company and Parent
shall file with the SEC a combined proxy and Registration Statement on Form S-4

in accordance with the terms of the letter agreement, entered into on August 10,
1998 and amended on September 18, 1998, (the "CONFIDENTIALITY AGREEMENT")
between Parent and the Company. The Company and Parent shall file all reports
required to be filed by each of them with the SEC between the date of this
Agreement and the Effective Time and shall deliver to the other party copies of
such reports promptly after the same are filed.
 
    SECTION 5.04.  CONSENTS; APPROVALS.  The Company and Parent shall each use
their reasonable efforts to obtain all consents, waivers, approvals,
authorizations or orders (including, without limitation, all governmental and
regulatory rulings and approvals), and the Company and Parent shall make all
filings (including, without limitation, all filings with governmental or
regulatory agencies) required in connection with the authorization, execution
and delivery of this Agreement by the Company and Parent and the consummation by
them of the transactions contemplated hereby. The Company and Parent shall
furnish all information required to be included in the Joint Proxy
Statement/Prospectus and the Registration Statement, or for any application or

other (or its counsel) with copies of all filings made by such party with any
state or federal government entity in connection with this Agreement or the
transactions contemplated hereby.
 
    SECTION 5.05.  AGREEMENTS OF AFFILIATES.  The Company shall deliver to
Parent, prior to the date the Registration Statement becomes effective under the
Securities Act, a letter (the "AFFILIATE LETTER") identifying all persons who
are, or may be deemed to be, at the time of the Company Stockholders' Meetings,
"affiliates" of the Company for purposes of Rule 145 under the Securities Act.
The Company shall use its best efforts to cause each person who is identified as
an "affiliate" in the Affiliate Letter to deliver to Parent, prior to the
Effective Time, a written agreement (an "AFFILIATE AGREEMENT") in a form
mutually agreeable to the Company and Parent.
 
    SECTION 5.06.  NOTIFICATION OF CERTAIN MATTERS.  The Company shall give
prompt notice to Parent, and Parent shall give prompt notice to the Company, of
(i) the occurrence or non-occurrence of any event the occurrence or
non-occurrence of which would be likely to cause any representation or warranty
contained in this Agreement to be materially untrue or inaccurate and (ii) any
failure of the Company, Parent or Merger Sub, as the case may be, to materially
comply with or satisfy any covenant, condition or agreement to be complied with
or satisfied by it hereunder; PROVIDED, HOWEVER, that the delivery of any notice
pursuant to this Section shall not limit or otherwise affect the remedies
available hereunder to the party receiving such notice and FURTHER PROVIDED that
failure to give such notice shall not be treated as a breach of covenant for the
purposes of Section 6.02(b) or 6.03(b) unless the failure to give such notice
results in material prejudice to the other party.
 
    SECTION 5.07.  FURTHER ASSURANCES; TAX TREATMENT.
 
    (a) Upon the terms and subject to the conditions hereof, each of the parties
hereto shall use all reasonable best efforts to take, or cause to be taken, all
actions and to do, or cause to be done, all other things necessary, proper or
advisable to consummate and make effective as promptly as practicable the
transactions contemplated by this Agreement, to obtain in a timely manner all
necessary waivers, consents and approvals and to effect all necessary
registrations and filings, and to otherwise satisfy or cause to be satisfied all
conditions precedent to its obligations under this Agreement. The foregoing
covenant shall not include any obligation by Parent to agree to divest, abandon,
license or take similar action with respect to any assets (tangible or
intangible) of Parent or the Company which, in the
 
                                      A-22
<PAGE>
reasonable judgment of Parent, would so materially adversely impact the economic
or business benefits of the transactions contemplated by this Agreement such
that a reasonable business person in such a situation would not proceed with the
consummation of the Merger.
 
    (b) Each of Parent, Merger Sub and the Company shall use its best efforts to
cause the Merger to qualify, and will not (both before and after consummation of
the Merger) take any actions which could prevent the Merger from qualifying, as
a reorganization under the provisions of Section 368 of the Code. Without
limiting the generality of the foregoing, each of Parent and the Company shall
execute and deliver to MoFo, counsel to Parent, and Skadden, counsel to the
Company, tax certificates containing customary representations, respectively, at
such time or times as reasonably requested by such counsel in connection with
the delivery of an opinion with respect to the transactions contemplated hereby.
 
    SECTION 5.08.  EMPLOYEES, EMPLOYEE BENEFITS.
 
    (a) Parent will, or will cause the Company to, give individuals who are
employed by the Company and its subsidiaries as of the Effective Time ("AFFECTED
EMPLOYEES") full credit for purposes of eligibility, vesting, benefit accrual
(excluding, however, benefit accrual under any defined benefit pension plans)
and determination of the level of benefits under any employee benefit plans or
arrangements maintained by Parent or any subsidiary of Parent for such Affected
Employees' service with the Company or any subsidiary of the Company to the same
extent recognized by the Company immediately prior to the Effective Time.
 
    (b) Parent will, or will cause the Company to, (i) waive all limitations as
to preexisting conditions exclusions and waiting periods with respect to
participation and coverage requirements applicable to the Affected Employees
under any welfare benefit plans that such employees may be eligible to
participate in after the Effective Time, other than limitations or waiting
periods that are already in effect with respect to such employees and that have
not been satisfied as of the Effective Time under any welfare plan maintained
for the Affected Employees immediately prior to the Effective Time, and (ii)
provide each Affected Employee with credit for any co-payments and deductibles
paid prior to the Effective Time in satisfying any applicable deductible or
out-of-pocket requirements under any welfare plans that such employees are
eligible to participate in after the Effective Time.
 
    (c) For a period of two years immediately following the Effective Time, the
coverage and benefits provided to Affected Employees who remain employed with
the Surviving Company, Parent or any subsidiary of Parent pursuant to employee
benefit plans or arrangements maintained by Parent, the Company, or any
subsidiary of Parent shall be, in the aggregate, not less favorable than those
provided to such employees immediately prior to the Effective Time.
 
    (d) As of the Effective Time, Parent shall assume and honor and shall cause
the Company to honor in accordance with their terms all employment, severance
and other compensation agreements and arrangements existing prior to the
execution of this Agreement which are between the Company or any subsidiary and
any director, officer or employee thereof (each an "EXECUTIVE AGREEMENT") except
as otherwise expressly agreed between Parent and such person. Parent and the
Company hereby agree that the consummation of the Merger shall constitute a
"Change in Control" for purposes of any Executive Agreement and all other
Company Employee Plans, pursuant to the terms of such plan. Parent's obligations
under this Section 5.08(d) are intended to be for the benefit of, and shall be
enforceable by, any Affected Employee to which such obligations relate.
 
    (e) Prior to the Effective Time the Company shall adopt, and following the
Effective Time Parent shall assume and honor in accordance with their terms, the
employee retention arrangements described in Section 5.08(e) of the Company
Disclosure Schedule.
 
    (f) For a period of sixty days immediately following the Effective Time,
Parent will, or will cause the Surviving Company to, continue to employ those
Affected Employees who are "affiliates" within
 
                                      A-23
<PAGE>
the meaning of Rule 144(a)(1) under the Securities Act on financial terms no
less favorable as those in effect immediately prior to the Effective Time.
Parent acknowledges and agrees that such continued employment for this sixty day
period shall not constitute a waiver on the part of any such employee of that
employee's rights to terminate his or her employment for "Good Reason" under the
terms of any Executive Agreement in effect as of the date hereof.
 
    SECTION 5.09.  PUBLIC ANNOUNCEMENTS.  Parent and the Company shall consult
with each other before issuing any press release with respect to the Merger or
this Agreement and shall not issue any such press release or make any such
public statement without the prior consent of the other party, which shall not
be unreasonably withheld; PROVIDED, HOWEVER, that a party may, without the prior
consent of the other party, issue such press release or make such public
statement as may upon the advice of counsel be required by law or the NYSE if it
has used all reasonable efforts to consult with the other party.
 
    SECTION 5.10.  LISTING OF PARENT COMMON STOCK.  Parent shall use its
commercially reasonable best efforts to cause the shares of Parent Common Stock
to be issued in the Merger to be approved for quotation on the NYSE prior to the
Effective Time.

the preparation, execution and filing of all returns, questionnaires,
applications, or other documents regarding any real property transfer or gains,
sales, use, transfer, value added, stock transfer and stamp taxes, any transfer,
recording, registration and other fees, and any similar taxes which become
payable by, and are imposed on, the Company in connection with the transactions
contemplated hereby that are required or permitted to be filed on or before the
Effective Time.
 
    SECTION 5.12.  POOLING ACCOUNTING TREATMENT.  Each of the parties will use
its best efforts to cause the transactions contemplated by this Agreement to be
accounted for as a pooling transaction by each party's independent certified
public accountants, by the NYSE and by the SEC, respectively, and each of the
parties agrees that it will take no action that would cause such accounting
treatment not to be obtained.
 
    SECTION 5.13.  INDEMNIFICATION, EXCULPATION AND INSURANCE.
 
    (a) Parent and the Company shall indemnify and hold harmless (including
attorneys' fees and the right to advancement of expenses) from liabilities for
acts or omissions occurring at or prior to the Effective Time each present and
former director, officer or employee of the Company or any of its subsidiaries
to the fullest extent permitted under applicable law, including against any
costs or expenses, judgments, fines, losses, claims, damages, liabilities and
amounts paid in settlement in connection with any claim, action, suit,
proceeding or investigation, whether civil, criminal, administrative or
investigative, and shall assume, without further action, as of the Effective
Time, any indemnification agreements of the Company in effect as of the date
hereof. In addition, from and after the Effective Time, directors and officers
of the Company who become directors or officers of Parent will be entitled to
indemnification under Parent's Restated Certificate of Incorporation and Bylaws,
as the same may be amended from time to time in accordance with their terms and
applicable law, and to all other indemnity rights and protections as are
afforded to other directors and officers of Parent.
 
    (b) In the event that Parent or any of its successors or assigns (i)
consolidates with or merges into any other person and is not the continuing or
surviving corporation or entity of such consolidation or merger or (ii)
transfers or conveys all or substantially all of its properties and assets to
any person, then, and in each such case, proper provision will be made so that
the successors and assigns of Parent assume the obligations set forth in this
Section 5.13.
 
    (c) For seven years after the Effective Time, Parent shall maintain in
effect the Company's current directors' and officers' liability insurance
covering acts or omissions occurring prior to the Effective Time with respect to
those persons who are currently covered by the Company's directors' and
officers'
 
                                      A-24
<PAGE>
liability insurance policy on terms with respect to such coverage and amount no
less favorable than those of such policy in effect on the date hereof; PROVIDED,
HOWEVER, that Parent may substitute therefor policies of Parent or its
subsidiaries containing terms with respect to coverage and amount no less
favorable to such directors or officers, and PROVIDED, FURTHER, that if the
aggregate annual premiums for such insurance at any time during such period

                                   ARTICLE VI
                            CONDITIONS TO THE MERGER
 
    SECTION 6.01.  CONDITIONS TO OBLIGATION OF EACH PARTY TO EFFECT THE
MERGER.  The respective obligations of each party to effect the Merger shall be
subject to the satisfaction at or prior to the Effective Time of the following
conditions:
 
        (a)  EFFECTIVENESS OF THE REGISTRATION STATEMENT.  The Registration
    Statement shall have been declared effective by the SEC under the Securities
    Act and the Merger contemplated hereby shall have been accounted for in the
    effective Registration Statement as a pooling of interests transaction. No
    stop order suspending the effectiveness of the Registration Statement shall
    have been issued by the SEC and no proceedings for that purpose and no
    similar proceeding in respect of the Joint Proxy Statement/Prospectus shall
    have been initiated or threatened by the SEC;
 
        (b)  NO INJUNCTIONS OR RESTRAINTS; ILLEGALITY.  No temporary restraining
    order, preliminary or permanent injunction or other order issued by any
    court of competent jurisdiction or other legal restraint or prohibition
    preventing the consummation of the Merger shall be in effect and no
    litigation by any governmental entity seeking any of the foregoing shall
    have been commenced. There shall not be any action taken, or any statute,
    rule, regulation or order enacted, entered, enforced or deemed applicable to
    the Merger, which makes the consummation of the Merger illegal;
 
        (c)  GOVERNMENT ACTIONS.  There shall not be any action taken, or any
    statute, rule, regulation or order enacted, entered, enforced or deemed
    applicable to the Merger, by any federal or state governmental entity which,
    in connection with the grant of a consent or the lapse of a waiting period
    which is necessary for the consummation of the Merger ("REQUISITE REGULATORY
    APPROVAL"), imposes any condition or restriction upon the Surviving Company
    or its subsidiaries (or, in the case of any disposition of assets required
    in connection with such Requisite Regulatory Approval, upon Parent or its
    subsidiaries), including, without limitation, requirements relating to the
    disposition of assets, which in any such case would so materially adversely
    impact the economic or business benefits of the transactions contemplated by
    this Agreement, such that a reasonable business person in such a situation
    would not proceed with the consummation of the Merger.
 
        (d)  POOLING OPINIONS.  The Company and Parent shall have received (i) a
    letter addressed to Parent from D&T, dated the date of the Merger, in
    response to a letter from Parent summarizing the relevant facts and in form
    and substance reasonably satisfactory to Parent, a copy of which shall be
    provided to the Company and (ii) a letter addressed to the Company from
    KPMG, dated the date of the Merger, in response to a letter from the Company
    summarizing the relevant facts and in form and substance reasonably
    satisfactory to the Company, a copy of which shall be
 
                                      A-25
<PAGE>
    provided to Parent, in each case to the effect that the Merger qualifies for
    "pooling of interests" treatment for financial accounting purposes and that
    such accounting treatment is in accordance with U.S. GAAP. D&T shall also
    have received from KPMG, a letter in form and substance satisfactory to D&T,
    dated the date of the Merger, that KPMG is not aware of any fact concerning
    the Company or any of its subsidiaries or affiliates that would preclude
    Parent from accounting for the Merger by the "pooling of interests" method
    for financial reporting purposes.
 
        (e)  HSR ACT.  The waiting period (and any extension thereof) applicable
    to the consummation of the Merger under the Hart-Scott-Rodino Antitrust
    Improvements Act of 1976, as amended (the "HSR ACT") shall have expired or
    been terminated.
 
        (f)  NYSE LISTING.  The shares of Parent Common Stock issuable to the
    Company's stockholders as contemplated by this Agreement shall have been
    approved for listing on the NYSE, subject to official notice of issuance.
 
        (g)  STOCKHOLDER APPROVAL.  This Agreement and the Merger shall have
    been approved and adopted by the requisite vote of the stockholders of the
    Company.
 
    SECTION 6.02.  ADDITIONAL CONDITIONS TO OBLIGATIONS OF PARENT AND MERGER
SUB.  The obligations of Parent and Merger Sub to effect the Merger are also
subject to the following conditions:
 
        (a)  REPRESENTATIONS AND WARRANTIES.  The representations and warranties
    of the Company contained in this Agreement shall be true and correct on and
    as of the Effective Time, except (i) for changes contemplated by this
    Agreement, (ii) those representations and warranties which address matters
    only as of a particular date (which shall remain true and correct as of such
    date), and (iii) where the failure of such representations and warranties to
    be so true and correct (without giving effect to any limitation as to
    "materiality" or "material adverse effect" set forth therein) would not have
    a Company Material Adverse Effect, with the same force and effect as if made
    on and as of the Effective Time, and Parent and Merger Sub shall have
    received a certificate to such effect signed by the President and Chief
    Financial Officer of the Company;
 
        (b)  AGREEMENTS AND COVENANTS.  The Company shall have performed or
    complied in all material respects with all agreements and covenants required
    by this Agreement to be performed or complied with by it on or prior to the
    Effective Time, and Parent and Merger Sub shall have received a certificate
    to such effect signed by the President and Chief Financial Officer of the
    Company;
 
        (c)  CONSENTS OBTAINED.  All material consents, waivers, approvals,
    authorizations or orders required to be obtained, and all filings required
    to be made ("MATERIAL CONSENTS"), by the Company for the authorization,
    execution and delivery of this Agreement and the consummation by it of the
    transactions contemplated hereby shall have been obtained and made by the
    Company, except where the failure to receive such Material Consents would
    not have a Material Adverse Effect on the Company or Parent;
 
        (d)  MATERIAL ADVERSE EFFECT.  Since the date of this Agreement, there
    shall not have been a Company Material Adverse Effect;
 
        (e)  AFFILIATE AGREEMENTS.  Parent shall have received from each person
    who is identified in the Affiliate Letter as an "affiliate" of the Company,
    an Affiliate Agreement, and such Affiliate Agreement shall be in full force
    and effect;
 
        (f)  FEES.  The sum of all fees paid and to be paid by the Company to
    Lehman Brothers Inc., KPMG and Skadden in connection with the transactions
    contemplated hereby, through and including the date of the Merger and as
    reflected in a final invoice from each of them delivered to the Company,
    with a copy to Parent, at least one business day prior to the date of the
    Merger, in the aggregate, shall be no more than $15,000,000; and
 
                                      A-26
<PAGE>
        (g)  TAX OPINION.  Parent shall have received the opinion of MoFo in
    form and substance reasonably satisfactory to Parent, on the basis of
    certain facts, representations (including representations contained in the
    certificates described below) and assumptions set forth in such opinion,
    dated the Effective Time, to the effect that the Merger will be treated for
    federal income tax purposes as a reorganization qualifying under the
    provisions of Section 368(a) of the Code and that each of Parent, Merger Sub
    and the Company will be a party to the reorganization within the meaning of
    Section 368(b) of the Code. In rendering such opinion, MoFo may rely upon
    and require representations contained in certificates of Parent, Merger Sub,
    the Company and others as are customary for such opinions.
 
    SECTION 6.03.  ADDITIONAL CONDITIONS TO OBLIGATION OF THE COMPANY.  The
obligation of the Company to effect the Merger is also subject to the following
conditions:
 
        (a)  REPRESENTATIONS AND WARRANTIES.  The representations and warranties
    of Parent and Merger Sub contained in this Agreement shall be true and
    correct on and as of the Effective Time, except (i) for changes contemplated
    by this Agreement, (ii) those representations and warranties which address
    matters only as of a particular date (which shall remain true and correct as
    of such date), and (iii) where the failure of such representations and
    warranties to be so true and correct (without giving effect to any
    limitation as to "materiality" or "material adverse effect" set forth
    therein) would not have, individually or in the aggregate, a Parent Material
    Adverse Effect, with the same force and effect as if made on and as of the
    Effective Time, and the Company shall have received a certificate to such
    effect signed by the President and Chief Financial Officer of Parent;
 
        (b)  AGREEMENTS AND COVENANTS.  Parent and Merger Sub shall have
    performed or complied in all material respects with all agreements and
    covenants required by this Agreement to be performed or complied with by
    them on or prior to the Effective Time, and the Company shall have received
    a certificate to such effect signed by the President and Chief Financial
    Officer of Parent;
 
        (c)  CONSENTS OBTAINED.  All Material Consents required to be obtained
    or made by Parent and Merger Sub for the authorization, execution and
    delivery of this Agreement and the consummation by them of the transactions
    contemplated hereby shall have been obtained and made by Parent and Merger
    Sub, except where the failure to receive such Material Consents would not
    have a Material Adverse Effect on the Company or Parent; and
 
        (d)  MATERIAL ADVERSE EFFECT.  Since the date of this Agreement, there
    shall not have been a Parent Material Adverse Effect.
 
        (e)  TAX OPINION.  The Company shall have received the opinion of
    Skadden, counsel to the Company, in form and substance reasonably
    satisfactory to the Company, on the basis of the facts, representations
    (including representations contained in the certificates described below)
    and assumptions set forth in such opinion, dated the Effective Time, to the
    effect that the Merger will be treated for federal income tax purposes as a
    reorganization qualifying under the provisions of Section 368(a) of the
    Code, and each of Parent, Merger Sub and the Company will be a party to the
    reorganization within the meaning of Section 368(b). In rendering such
    opinion, Skadden may rely upon and require representations contained in
    certificates of Parent, Merger Sub, the Company and others as are customary
    for such opinions.

prior to the Effective Time, notwithstanding approval thereof by the
stockholders of the Company:
 
        (a) by mutual written consent duly authorized by the Boards of Directors
    of Parent and the Company; or
 
        (b) by either Parent or the Company if the Merger shall not have been
    consummated by June 30, 1999 (provided that the right to terminate this
    Agreement under this Section 7.01(b) shall not be available to any party
    whose failure to fulfill any obligation under this Agreement has been the
    cause of or resulted in the failure of the Merger to occur on or before such
    date); or
 
        (c) by either Parent or the Company if a court of competent jurisdiction
    or governmental, regulatory or administrative agency or commission shall
    have issued a non-appealable final order, decree or ruling or taken any
    other action, in each case having the effect of permanently restraining,
    enjoining or otherwise prohibiting the Merger, except if the party relying
    on such order, decree or ruling or other action has not complied with its
    obligations under Section 5.07; or
 
        (d) by Parent or the Company if, at the Company Stockholders' Meeting
    (including any adjournment or postponement thereof), the requisite vote of
    the stockholders of the Company shall not have been obtained; or
 
        (e) by Parent, if (i) the board of directors of the Company shall
    withdraw, modify or change its recommendation of this Agreement or the
    Merger in a manner adverse to Parent or shall have resolved to do any of the
    foregoing; (ii) the board of directors of the Company shall have recommended
    to the stockholders of the Company an Alternative Transaction (as defined in

    in such tender or exchange offer; or
 
        (f) by the Company, if it shall exercise the right specified in clause
    (ii) of Section 4.02(a), provided that the Company may not effect such
    termination pursuant to this Section 7.01(f) unless and until it shall have
    paid Parent an amount in cash equal to the Fee (as defined herein); or
 
        (g) by Parent or the Company, upon a breach of any representation,
    warranty, covenant or agreement on the part of the Company or Parent,
    respectively, set forth in this Agreement such that the conditions set forth
    in Section 6.02(a) or 6.02(b), or Section 6.03(a) or 6.03(b), would not be
    satisfied (a "TERMINATING BREACH"), PROVIDED, that if such Terminating
    Breach is curable prior to June 30, 1999 by Parent or the Company, as the
    case may be, through the exercise of its reasonable best efforts and for so
    long as Parent or the Company, as the case may be, continues to exercise
    such reasonable best efforts, neither the Company nor Parent, respectively,
    may terminate this Agreement under this Section 7.01.
 
    SECTION 7.02.  EFFECT OF TERMINATION.  In the event of the termination of
this Agreement pursuant to Section 7.01, this Agreement shall forthwith become
void and there shall be no liability on the part of any party hereto or any of
its affiliates, directors, officers or stockholders except (i) as set forth in
Sections 7.03 and 8.01 hereof, and (ii) nothing herein shall relieve any party
from liability for any willful breach hereof.

expenses, if the Merger is not consummated or (ii) if the Merger is consummated,
then the Surviving Company shall pay all such fees and expenses; PROVIDED,

related thereto) and the Registration Statement (including financial statements
and exhibits) and any amendments or supplements thereto.

Company and its subsidiaries, taken as a whole, or (iv) merger, consolidation,

Board of Directors
First Brands Corporation
Danbury, CT 06813
 
Members of the Board:
 
    We understand that First Brands Corporation ("First Brands" or the
"Company"), The Clorox Company ("Clorox") and Pennant, Inc., a wholly owned
subsidiary of Clorox ("Pennant"), are proposing to enter into an Agreement and
Plan of Reorganization and Merger, dated as of October 18, 1998 (the
"Agreement"), providing, among other things, for the merger (the "Merger" or the
"Proposed Transaction") of Pennant into First Brands, whereby First Brands will
become a wholly owned subsidiary of Clorox. Upon the effectiveness of the
Merger, and so long as the average of the closing prices of Clorox common stock
quoted on the New York Stock Exchange during the ten trading days preceding the
fifth trading day prior to the effective date of the Merger (the "Clorox Average
Price") is between $80 and $115 per share, each issued and outstanding share of
First Brands' common stock shall be converted into the right to receive a number
of shares of Clorox common stock determined by dividing $39.00 by the Clorox
Average Price (the quotient resulting from the above calculation being referred
to as the "Fixed Price Ratio"). In the event the Clorox Average Price is $80 or
below, each issued and outstanding share of First Brands' common stock shall be
converted on the effective date of the Merger into 0.4875 shares of Clorox
common stock (the "Ratio Cap"). In the event the Clorox Average Price is $115 or
above, each issued and outstanding share of First Brands' common stock shall be
converted on the effective date of the Merger into 0.3391 shares of Clorox
common stock (the "Ratio Floor" and together with the Ratio Cap and the Fixed
Price Ratio, the "Exchange Ratio"). The terms and conditions of the Proposed
Transaction are set forth in more detail in the Agreement.
 
    We have been requested by the Board of Directors of the Company to render
our opinion with respect to the fairness, from a financial point of view, to the
stockholders of the Company of the Exchange Ratio to be offered to such
stockholders in the Proposed Transaction. We have not been requested to opine as
to, and our opinion does not in any manner address, the Company's underlying
business decision to proceed with or effect the Proposed Transaction.
 
    In arriving at our opinion, we reviewed and analyzed: (1) the Agreement and
the specific terms of the Proposed Transaction, (2) such publicly available
information concerning the Company and Clorox that we believe to be relevant to
our analysis, including the Annual Reports on Form 10-K for the fiscal years
ended June 30, 1997 and June 30, 1998, (3) financial and operating information
with respect to the business, operations and prospects of the Company furnished
to us by the Company, (4) financial and operating information with respect to
the business and operations of Clorox furnished to us by Clorox, (5) the trading
history of the Company's common stock from October 15, 1993 to the present and a
comparison of that trading history with those of other companies that we deemed
relevant, (6) the trading history of Clorox's common stock from October 15, 1993
to the present and a comparison of that trading history with those of other
companies that we deemed relevant, (7) a comparison of the historical financial
results and present financial condition of the Company with those of other
companies that we deemed relevant, (8) a comparison of the historical financial
results and present financial condition of Clorox with those of other companies
that we deemed relevant, (9) a comparison of the financial terms of the Proposed
Transaction with the financial terms of certain other
 
                                      B-1
<PAGE>
transactions that we deemed relevant, (10) the proforma impact of the Proposed
Transaction on Clorox, (11) estimates of third party research analysts with
respect to the future financial performance of First Brands and Clorox and (12)
an indication of interest received by the Company from another party with
respect to an acquisition of the Company. In addition, we have had discussions
with the managements of the Company and Clorox concerning their respective
businesses, operations, assets, financial conditions and prospects and with the
management of the Company concerning the cost savings and other strategic
benefits expected by them to result from a combination of the businesses of
First Brands and Clorox, and have undertaken such other studies, analyses and
investigations as we deemed appropriate.
 
    In arriving at our opinion, we have assumed and relied upon the accuracy and
completeness of the financial and other information used by us without assuming
any responsibility for independent verification of such information and have
further relied upon the assurances of managements of the Company and Clorox that
they are not aware of any facts or circumstances that would make such
information inaccurate or misleading. With respect to the financial projections
of the Company for fiscal year 1999, upon advice of the Company we have assumed
that such projections have been reasonably prepared on a basis reflecting the
best currently available estimates and judgments of the management of the
Company as to the future financial performance of the Company and that the
Company will perform substantially in accordance with such projections. In
addition, for purposes of our analysis, we also extrapolated the financial
trends of the latest three fiscal years and the Company's projections for fiscal
year 1999 to develop financial projections for the Company for the fiscal years
2000 through 2003, and then considered certain more conservative assumptions and
estimates which resulted in certain adjustments to such projections. We have
discussed the extrapolation process, the resulting projections and the adjusted
projections with the management of the Company and they have agreed with the
appropriateness of the extrapolation process and the use of the resulting
projections and the adjusted projections in performing our analysis. In arriving
at our opinion, we were not provided with, and did not have access to, any
financial projections prepared by the management of Clorox. Accordingly, with
respect to the future financial performance of Clorox on a stand alone basis,
upon advice of Clorox we have assumed that the published estimates of third
party research analysts are a reasonable basis upon which to evaluate the future
financial performance of Clorox on a stand alone basis and that Clorox would
perform, on a stand alone basis, substantially in accordance with those
estimates. In arriving at our opinion, we have not conducted a physical
inspection of the properties and facilities of the Company and have not made or
obtained any evaluations or appraisals of the assets or liabilities of the
Company. In addition, you have not authorized us to solicit, and we have not
solicited, any indications of interest from any third party with respect to the
purchase of all or a part of the Company's businesses. Upon the advice of the
Company and Clorox, we have assumed that the Merger will qualify for
pooling-of-interests accounting treatment, and upon the advice of the Company,
Clorox and their respective legal advisors, we have assumed that the Merger will
qualify as a reorganization within the meaning of Section 368(a) of the Internal
Revenue Code of 1986, as amended, and therefore as a tax-free transaction to the
stockholders of the Company. Our opinion necessarily is based upon market,
economic and other conditions as they exist on, and can be evaluated as of, the
date of this letter.
 
    Based upon and subject to the foregoing, we are of the opinion as of the
date hereof that, from a financial point of view, the Exchange Ratio to be
offered to the stockholders of the Company in the Proposed Transaction is fair
to such stockholders.
 
    We have acted as financial advisor to the Company in connection with the
Proposed Transaction and will receive a fee for our services which is contingent
upon the consummation of the Proposed Transaction. In addition, the Company has
agreed to indemnify us for certain liabilities that may arise out of the
rendering of this opinion. In the ordinary course of our business, we actively
trade in the debt and equity securities of the Company and Clorox for our own
account and for the accounts of our customers and, accordingly, may at any time
hold a long or short position in such securities.

    This opinion is for the use and benefit of the Board of Directors of the
Company and is rendered to the Board of Directors in connection with its
consideration of the Proposed Transaction. This opinion is not intended to be
and does not constitute a recommendation to any stockholder of the Company as to
how such stockholder should vote with respect to the Proposed Transaction.
 
                                Very truly yours,

                     INFORMATION NOT REQUIRED IN PROSPECTUS
 
ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
    Section 145(a) of the Delaware General Corporation Law (the "DGCL") provides
in relevant part 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, suit or proceeding, whether civil, criminal, administrative or
investigative (other than an action by or in the right of the corporation), by
reason of the fact that he is or was a director, officer, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise,
against expenses (including attorneys' fees), judgments, fines and amounts paid
in settlement actually and reasonably incurred by him in connection with such
action, suit or proceeding if he acted in good faith and in a manner he
reasonably believed to be in or not opposed to the best interest of the
corporation, and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful." With respect to
derivative actions, Section 145(b) of the DGCL provides in relevant part 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 suit by or
in the right of the corporation to procure a judgment in its favor..............
                                                                            [by
reason of his service in one of the capacities specified in the preceding
sentence] against expenses (including attorneys' fees) actually and reasonably
incurred by him in connection with the defense or settlement of such action or
suit if he acted in good faith and in a manner he reasonably believed to be in
or not opposed to the best interest of the corporation and except that no
indemnification shall be made in respect of any claim, issue or matter as to
which such person shall have been adjudged to be liable to the corporation
unless and only to the extent that the Court of Chancery or the court in which
such action or suit was brought shall determine upon application that, despite
the adjudication of liability but in view of all the circumstances of the case,
such person is fairly and reasonably entitled to indemnity for such expenses
which the Court of Chancery or such other court shall deem proper."
 
    The Registrant's Restated Certificate of Incorporation provides that the
Registrant is required to indemnify to the full extent permitted by the DGCL any
person made, or threatened to be made, a party to an action or proceeding,
whether criminal, civil, administrative or investigative, by reason of the fact
that the person, or the testator or intestate of such person, is or was a
director or officer of the Registrant, or served any business as a director or
officer at the request of the Registrant. Expenses incurred by a director of the
Registrant in defending a civil or criminal action, suit or proceeding by reason
of the fact that such person was a director of the Registrant (and not in any
other capacity, including if such person was serving at the Registrant's request
as a director or officer of another enterprise or corporation) will be paid by
the Registrant in advance of the final disposition of such action, suit or
proceeding upon receipt of an undertaking by or on behalf of such director to
repay such amount if it shall ultimately be determined that such person is not
entitled to be indemnified by the Registrant as authorized by relevant sections
of the DGCL. The Registrant will indemnify officers or directors in connection
with a proceeding initiated by them only if such proceeding was authorized by
the Registrant's Board of Directors. Any person who is not paid pursuant to the
foregoing indemnification provisions 90 days after submitting a written claim to
the Registrant may sue to recover such unpaid amounts and, if successful, will
be entitled to be paid the expense of prosecuting such claim (except for any
such claims as the Registrant is not permitted by law to indemnify, although the
burden of proving such defense will be on the Registrant).
 
    Such Restated Certificate of Incorporation also provides that no director
will be liable to the Registrant for a breach of fiduciary duty, except (1) for
any breach of the director's duty of loyalty to the Registrant or its
stockholders, (2) for acts or omissions not in good faith or which involve
intentional misconduct or a knowing violation of the law, (3) under Section 174
of the DGCL, or (4) for any transaction from which the director derived an
improper personal benefit. The Registrant may also
 
                                      II-1
<PAGE>
maintain insurance at its expense, to protect itself and any director or officer
of the Registrant or of another corporation or other enterprise against any
expense, liability or loss, whether or not the Registrant would have the power
to indemnify such person against such expense, liability or loss under the DGCL.
 
    The Registrant has purchased and maintains insurance on behalf of any person
who is or was a director or officer against loss arising from any claim asserted
against him and incurred by him in any such capacity, subject to certain
exclusions.

ITEM 22. UNDERTAKINGS.
 
    (1) The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933 (the "Act"), each
filing of the Registrant's annual report pursuant to Section 13(a) or Section
15(d) of the Securities Exchange Act of 1934 that is incorporated by reference
in the Registration Statement shall be deemed to be a new Registration Statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.
 
    (2) The undersigned Registrant hereby undertakes as follows: that prior to
any public reoffering of the securities registered hereunder through use of a
prospectus which is part of this Registration Statement, by any person or party
who is deemed to be an underwriter within the meaning of Rule 145(c), the issuer
undertakes that such reoffering prospectus will contain the information called
for by the applicable registration form with respect to reofferings by persons
who may be deemed underwriters, in addition to the information called for by the
other items of the applicable form.
 
    (3) The Registrant undertakes that every prospectus: (i) that is filed
pursuant to paragraph (2) immediately preceding, or (ii) that purports to meet
the requirements of Section 10(a)(3) of the Act, and is used in connection with
an offering of securities subject to Rule 415, will be filed as part of an
amendment to the Registration Statement and will not be used until such
amendment is effective, and that, for purposes 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.
 
    (4) The undersigned Registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Items 4, 10(b), 11 or 13 of this form, within
 
                                      II-2
<PAGE>
one business day of receipt of such request, and to send the incorporated
documents by first class mail or other equally prompt means. This includes
information contained in documents filed subsequent to the effective date of the
Registration Statement through the date of responding to the request.
 
    (5) The undersigned Registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the Registration Statement when it became effective.
 
    (6) Insofar as indemnification for liabilities arising under the Act may be
permitted to directors, officers and controlling persons of the Registrant
pursuant to the foregoing provisions hereof, or otherwise, the Registrant has
been advised that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the Registrant of expenses incurred
or paid by a director, officer or controlling person of the Registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.

    Re:  The Clorox Company:
       20,394,076 Shares of Common Stock
 
Ladies and Gentlemen:
 
    At your request, we have examined the Registration Statement on Form S-4
(the "Registration Statement") filed by you with the Securities and Exchange
Commission on December 22, 1998, in connection with the registration under the
Securities Act of 1933, as amended, of 20,394,076 shares of your Common Stock,
par value of $0.01 per share (the "Common Stock"). The Common Stock is to be
issued to the former stockholders of First Brand Corporation, a Delaware
corporation ("First Brands"), pursuant to the terms of that certain Agreement
and Plan of Merger, dated as of October 18, 1998, by and between you, Pennant,
Inc., a Delaware corporation and your wholly owned subsidiary, and First Brands
(the "Merger Agreement").
 
    In connection with this opinion, we have examined all proceedings taken by
you relating to the issuance of up to 20,394,076 shares of the Common Stock.
 
    It is our opinion that the shares of Common Stock being issued by you in
exchange for the shares of common stock of First Brands pursuant to the Merger
Agreement, when issued in the manner referred to in the Registration Statement,
will be legally and validly issued, fully paid, and nonassessable.
 
    We consent to the use of this opinion as an exhibit to the Registration
Statement and further consent to all references to us in the Registration
Statement, the Proxy Statement/Prospectus constituting a part thereof, and any
amendments thereto.
 
                                          Very truly yours,

The Clorox Company

Oakland, CA 94612
 
Ladies and Gentlemen:
 
    We have acted as counsel to the Clorox Company ("Clorox"), a Delaware
corporation, in connection with the proposed merger (the "Merger") of Pennant,
Inc. ("Merger Sub"), a Delaware corporation and a direct wholly-owned subsidiary
of Clorox, with and into First Brands Corporation, a Delaware corporation
("First Brands"), pursuant to an Agreement and Plan of Merger dated as of
October 18, 1998 (the "Merger Agreement") by and among Clorox, Merger Sub and
First Brands. The Merger is described in the Registration Statement of Clorox on
Form S-4 (the "Registration Statement") filed on the date hereof with the
Securities and Exchange Commission (the "Commission") under the Securities Act
of 1933, as amended (the "Securities Act"), which includes the combined proxy
statement of First Brands and the prospectus of Clorox (the "Proxy
Statement/Prospectus").
 
    In that connection, we have reviewed the Merger Agreement, the Proxy
Statement/Prospectus and such other materials as we have deemed necessary or
appropriate for purposes of our opinion. In addition, we have assumed (i) that
the Merger will be consummated in accordance with the provisions of the Merger
Agreement and as contemplated by the Proxy Statement/Prospectus and (ii) the
truth and accuracy, on the date of the Merger Agreement and on the date hereof,
of the representations and warranties made by Clorox, Merger Sub and First
Brands in the Merger Agreement.
 
    Based upon and subject to the foregoing, it is our opinion that the
discussion contained in the Registration Statement under the captions
"SUMMARY--The Merger--Material Federal Income Tax Consequences" and "THE
MERGER--Material Federal Income Tax Consequences", to the extent that it
pertains to matters of law or legal conclusions, is correct in all material
respects. Because this opinion is being delivered prior to the effective time of
the Merger, it must be considered prospective and dependent upon future events.
There can be no assurance that changes in the law will not take place which
could affect the Federal income tax consequences of the Merger or that contrary
positions may not be asserted by the Internal Revenue Service.
 
    This opinion is being furnished in connection with the Registration
Statement. You may rely upon and refer to the foregoing opinion in the Proxy
Statement/Prospectus. Any variation or difference in any fact from those set
forth or assumed either herein or in the Proxy Statement/Prospectus may affect
the conclusions stated herein.
 
    We hereby consent to the use of our name under the caption "THE
MERGER--Material Federal Income Tax Consequences" in the Proxy
Statement/Prospectus and to the filing of this opinion as an Exhibit to the
Registration Statement. In giving this consent, we do not admit that we come
within the category of persons whose consent is required under Section 7 of the
Securities Act or the rules and regulations of the Commission thereunder.
 
                                          Very truly yours,

First Brands Corporation

P.O. Box 1911

Gentlemen:
 
    You have requested our opinion regarding the discussions of the material
United States Federal income tax consequences under the captions "SUMMARY--The
Merger--Material Federal Income Tax Consequences" and the "THE MERGER--Material
Federal Income Tax Consequences" in the combined Proxy Statement of First Brands
Corporation ("First Brands") and Prospectus of the Clorox Company ("Clorox")
which is included (the "Proxy Statement/Prospectus") in the Registration
Statement on Form S-4 (the "Registration Statement") filed on the date hereof
with the Securities and Exchange Commission (the "Commission") under the
Securities Act of 1933, as amended (the "Securities Act"). The Proxy
Statement/Prospectus relates to the proposed merger (the "Merger") of Pennant,
Inc. ("Merger Sub"), a direct wholly-owned subsidiary of Clorox, with and into
First Brands, with First Brands being the surviving corporation in the Merger.
This opinion is delivered in accordance with the requirements of Item 601(b)(8)
of Regulation S-K under the Securities Act.
 
    In rendering our opinion, we have reviewed the Proxy Statement/Prospectus
and such other materials as we have deemed necessary or appropriate as a basis
for our opinion. In addition, we have considered the applicable provisions of
the Internal Revenue Code of 1986, as amended (the "Code"), Treasury Regulations
promulgated thereunder by the Treasury Department (the "Regulations"), pertinent
judicial authorities, rulings of the Internal Revenue Service (the "IRS") and
such other authorities as we have considered relevant, in each case, in effect
on the date hereof. It should be noted that such Code, Regulations, judicial
decisions, administrative interpretations and such other authorities are subject
to change at any time and, in some circumstances, with retroactive effect. A
material change in any of the materials or authorities upon which our opinion is
based could affect our conclusions stated herein.
 
    Based upon the foregoing, it is our opinion that the statements made under
the captions "SUMMARY--The Merger--Material Federal Income Tax Consequences" and
"THE MERGER--Material Federal Income Tax Consequences" in the Proxy
Statement/Prospectus, to the extent that they constitute matters of law or legal
conclusions, are correct in all material respects. There can be no assurance
that contrary positions may not be asserted by the IRS.
 
    This opinion is being furnished in connection with the Proxy
Statement/Prospectus. You may rely upon and refer to the foregoing opinion in
the Proxy Statement/Prospectus. Any variation or difference in any fact from
those set forth or assumed either herein or in the Proxy Statement/Prospectus
may affect the conclusions stated herein.
 
    In accordance with the requirements of Item 601(b)(23) of Regulation S-K
under the Securities Act, we hereby consent to the use of our name under the
caption "THE MERGER--Material Federal Income Tax Consequences" in the Proxy
Statement/Prospectus and to the filing of this opinion as an Exhibit to the
Registration Statement. In giving this consent, we do not admit that we come
within the category of persons whose consent is required under Section 7 of the
Securities Act or the rules and regulations of the Commission thereunder.
