    Act of 1933, as amended (the "Securities Act"), and Rule 457(c) thereunder,
    by multiplying 1/33 of 1% times the proposed maximum aggregate offering

    this Registration Statement.

Dear Stockholder:
 
     A Special Meeting of the stockholders of The Gillette Company will be held
at 10:00 a.m. on Monday, December 30, 1996, at the Sheraton Boston Hotel, 39
Dalton Street, Boston, Massachusetts.
 
     At the Special Meeting, holders of shares of Gillette stock will be asked
to consider and vote upon a proposal to approve the issuance of shares of
Gillette common stock pursuant to an Agreement and Plan of Merger ("Merger
Agreement"), dated as of September 12, 1996, among Gillette, a wholly-owned
subsidiary of Gillette, and Duracell International Inc. Pursuant to the Merger
Agreement, Gillette's subsidiary will be merged into Duracell (the "Merger"),
and Duracell will become a wholly-owned subsidiary of Gillette. In the Merger,
each outstanding share of Duracell common stock will be converted into the right
to receive 0.904 shares of Gillette common stock and each outstanding option to
purchase Duracell common stock will become an option to purchase Gillette common
stock.
 
     Your Board of Directors has carefully reviewed and considered the terms and
conditions of the Merger and has received the opinions of Merrill Lynch, Pierce,
Fenner & Smith Incorporated and J. P. Morgan Securities Inc., its financial
advisors, that, as of September 12, 1996 and based on and subject to certain
matters stated therein, the consideration to be paid by Gillette in the Merger
was fair to Gillette from a financial point of view. Copies of these opinions
are attached as Annexes B and C to the accompanying Joint Proxy
Statement/Prospectus. THE BOARD OF DIRECTORS OF GILLETTE HAS DETERMINED THAT THE
MERGER IS FAIR TO GILLETTE AND IN THE BEST INTERESTS OF ITS STOCKHOLDERS.
ACCORDINGLY, THE BOARD OF DIRECTORS HAS APPROVED THE MERGER AGREEMENT AND
RECOMMENDS THAT YOU VOTE IN FAVOR OF THE ISSUANCE OF SHARES OF GILLETTE COMMON
STOCK IN CONNECTION WITH THE MERGER.
 
     Your vote is important regardless of how many shares you own. Please take a
few minutes now to review the proxy statement and to sign and date your proxy
and return it in the envelope provided. You may attend the meeting and vote in
person even if you have previously returned your proxy.
 
                                          Sincerely,

                              THE GILLETTE COMPANY
                                   PROSPECTUS
 
     This Joint Proxy Statement and Prospectus ("Joint Proxy
Statement/Prospectus") is being furnished to the holders of common stock, par
value $1.00 per share (together with the preferred stock purchase rights
attached thereto, the "Gillette Common Stock"), and Series C ESOP Convertible
Preferred Stock, no par value (together with the preferred stock purchase rights
attached thereto, the "ESOP Preferred Stock" and, together with the Gillette
Common Stock, the "Gillette Stock"), of The Gillette Company, a Delaware
corporation ("Gillette"), in connection with the solicitation of proxies by the
Board of Directors of Gillette for use at a Special Meeting of Stockholders of
Gillette to be held at the Sheraton Boston Hotel, 39 Dalton Street, Boston,
Massachusetts on December 30, 1996 at 10:00 a.m., and at any and all
adjournments or postponements thereof (the "Gillette Special Meeting"). This
Joint Proxy Statement/Prospectus also constitutes the Prospectus of Gillette
with respect to shares of Gillette Common Stock issuable to stockholders of
Duracell International Inc., a Delaware corporation ("Duracell"), in connection
with the proposed merger (the "Merger") of Alaska Acquisition Corp., a Delaware
corporation and a wholly-owned subsidiary of Gillette ("Merger Sub"), with and
into Duracell pursuant to the Agreement and Plan of Merger dated as of September
12, 1996, by and among Gillette, Merger Sub and Duracell (the "Merger
Agreement"). Gillette Common Stock is traded on the New York Stock Exchange,
Inc. (the "NYSE") under the symbol "G." On November 22, 1996, the closing sale
price for Gillette Common Stock as reported on the NYSE Composite Transactions
Tape was $73 7/8 per share.
 
     This Joint Proxy Statement/Prospectus is also being furnished to the
holders of common stock, par value $0.01 per share ("Duracell Common Stock"), of
Duracell in connection with the solicitation of proxies by the Board of
Directors of Duracell for use at a Special Meeting of Stockholders of Duracell
to be held at the Ethan Allen Inn, 21 Lake Avenue Extension, Danbury,
Connecticut on December 30, 1996, at 10:00 a.m., and at any and all adjournments
or postponements thereof (the "Duracell Special Meeting").
 
     Based upon the exchange ratio of 0.904 shares of Gillette Common Stock for
each share of Duracell Common Stock and the number of shares of Duracell Common
Stock and of options to purchase Duracell Common Stock under the Duracell Stock
Option Plans (as defined) outstanding at November 1, 1996, Gillette would issue
approximately 109,026,398 shares of Gillette Common Stock to Duracell
stockholders in the Merger and would assume options to purchase Duracell Common
Stock which would be converted into options to purchase approximately 5,125,513
shares of Gillette Common Stock.
 
     This Joint Proxy Statement/Prospectus and the accompanying forms of proxy
are first being mailed to stockholders of Gillette and Duracell on or about
November 29, 1996.

     The Special Meeting of Gillette's stockholders will be held at the Sheraton
Boston Hotel, 39 Dalton Street, Boston, Massachusetts on December 30, 1996, at
10:00 a.m. (including any and all adjournments or postponements thereof, the
"Gillette Special Meeting").
 
     The Special Meeting of Duracell's stockholders will be held at the Ethan

PURPOSE OF THE MEETINGS
 
  The Gillette Special Meeting
 
     At the Gillette Special Meeting, holders of Gillette Stock will consider
and vote upon the issuance of Gillette Common Stock in connection with the
Merger Agreement (the "Gillette Share Proposal"). Based
 
                                        3
<PAGE>   13
 
upon the shares of Gillette Common Stock, shares of Duracell Common Stock and
options to purchase Duracell Common Stock under the Duracell Stock Option Plans
outstanding as of November 1, 1996 and an exchange ratio of 0.904 shares of
Gillette Common Stock for each share of Duracell Common Stock (the "Exchange
Ratio"), Gillette would issue approximately 109,026,398 shares of Gillette
Common Stock to Duracell stockholders in the Merger, representing approximately
20% of outstanding Gillette Common Stock following consummation of the Merger,
and Gillette would assume options to purchase Duracell Common Stock which would
be converted into options to purchase approximately 5,125,513 shares of Gillette
Common Stock. Following consummation of the Merger, Henry R. Kravis, who is
currently a director of Duracell, will be appointed to the Gillette Board of
Directors by the directors of Gillette. Holders of Gillette Stock may also
consider and vote upon matters incident to the conduct of the Gillette Special
Meeting.

  The Duracell Special Meeting
 
     At the Duracell Special Meeting, holders of Duracell Common Stock will
consider and vote upon a proposal (the "Duracell Merger Proposal") to approve
and adopt the Merger Agreement providing for the merger of Merger Sub with and

AGREEMENT AND RECOMMENDS THAT DURACELL STOCKHOLDERS VOTE FOR THE DURACELL MERGER

require approval by the affirmative vote of the holders of a majority of the

and entitled to vote. Holders of Gillette Common Stock are entitled to one vote

of ESOP Preferred Stock, representing in the aggregate approximately 11.2% of
the voting power of the outstanding Gillette Stock on such date. Such directors
and executive officers of Gillette have indicated to Gillette that they and
their affiliates presently intend to vote all such shares in favor of the
Gillette Share Proposal.
 
     Duracell.  The Duracell Merger Proposal will require the affirmative vote
of the holders of a majority of the outstanding shares of Duracell Common Stock.
Holders of Duracell Common Stock are entitled to one vote per share. Only
holders of Duracell Common Stock at the close of business on November 1, 1996
(the "Duracell Record Date") will be entitled to notice of and to vote at the

Stockholders") beneficially own 41.1 million shares of Duracell Common Stock,
representing approximately 34% of the Duracell Common Stock entitled to vote at
the Duracell Special Meeting. Pursuant to a Stockholders Agreement dated as of
September 12, 1996 between Gillette and the KKR Stockholders ("the Stockholders
Agreement"), the KKR Stockholders have agreed, among other things, to vote in
favor of the Duracell Merger Proposal and have granted Merger Sub an irrevocable
proxy to vote their shares of Duracell Common Stock in accordance
 
                                        4

                                   THE MERGER
 
THE MERGER
 
     Pursuant to the Merger Agreement, Merger Sub will be merged with and into
Duracell and Duracell will become a wholly-owned subsidiary of Gillette.
 
MERGER CONSIDERATION
 
     Pursuant to the Merger, each outstanding share of Duracell Common Stock
(other than shares owned by Duracell as treasury stock or by its subsidiaries or
by Gillette or its subsidiaries, all of which shall be canceled) will be
converted into the right to receive 0.904 shares of Gillette Common Stock. See
"The Merger Agreement -- Terms of the Merger."
 
EXCHANGE OF CERTIFICATES
 
     As soon as practicable after the filing of a certificate of merger with the
Secretary of State of the State of Delaware (the time of such filing being the
"Effective Time"), The First National Bank of Boston, as exchange agent for the
Merger (the "Exchange Agent"), will send a transmittal letter to each Duracell
stockholder. The transmittal letter will contain instructions with respect to
the surrender of certificates representing Duracell Common Stock to be exchanged
for Gillette Common Stock. See "The Merger Agreement -- Exchange of
Certificates."
 
     DURACELL STOCKHOLDERS SHOULD NOT FORWARD CERTIFICATES FOR DURACELL COMMON

preventing or restricting the consummation of the Merger; (vi) receipt of

nonappealable final order permanently enjoining or otherwise prohibiting the
Merger (provided that such right to terminate the Merger Agreement shall not be
available to any party who has not complied with its obligations described under
"The Merger Agreement -- Additional Agreements -- Further Action; Tax Treatment"
and such noncompliance materially contributed to the issuance of any such
order); (iv) by Gillette or Duracell, if the requisite vote of the stockholders
of Duracell or Gillette, respectively, shall not have been obtained at a duly
held meeting of such stockholders or any adjournments thereof by March 31, 1997;
(v) by Gillette or Duracell, if the Board of Directors of Duracell withdraws,
modifies or changes its approval or recommendation of the Merger Agreement or
the Merger in a manner adverse to Gillette or shall have resolved to do so
(provided that the Board of Directors of Duracell may take any action specified
in this clause (v) only if required to do so under applicable fiduciary duties
as determined by such Board in good faith after consultation with and based upon
the written advice of its outside legal counsel); (vi) by Gillette or Duracell,
if the Board of Directors of Duracell, recommends to the stockholders of
Duracell an Alternative Transaction (as defined in "The Merger
Agreement -- Termination") or recommends that the stockholders of Duracell
tender their shares in a tender or exchange offer by a person other than
Gillette or an affiliate of Gillette for 15% or more of the outstanding Duracell
Common Stock (provided that Duracell shall not be entitled to exercise any
termination rights under this clause (vi) unless (x) any action of the Board of
Directors of Duracell referred to in this clause (vi) is required to be taken by
such Board of Directors in order to properly discharge its fiduciary duties and
(y) Duracell has complied with its obligations described under "The Merger
Agreement -- Conduct of Business Pending the Merger -- No Solicitation by
Duracell"); or (vii) by Duracell, if the Board of Directors of Gillette
withdraws, modifies or changes its approval or recommendation of the Merger
Agreement or the Merger in a manner adverse to Duracell or shall have resolved
to do so (provided that the Board of Directors of Gillette may take any action
specified in this clause (vii) only if required to do so under applicable
fiduciary duties as determined by such Board in good faith after consultation
with and based upon the written advice of its outside legal counsel). See "The
Merger Agreement -- Termination -- Conditions to Termination."
 
     The Merger Agreement requires Duracell to pay Gillette a fee of $150
million plus actual, documented and reasonable out-of-pocket expenses of
Gillette relating to the transactions contemplated by the Merger Agreement of up
to $15 million upon termination of the Merger Agreement (i) by Gillette or
Duracell, because the Duracell Board of Directors recommends to the stockholders
of Duracell an Alternative Transaction or recommends that the stockholders of
Duracell tender their shares in a tender or exchange offer, as set forth above,
(ii) by Gillette or Duracell, because the Duracell Board of Directors withdraws,
modifies or changes its approval or recommendation of the Merger Agreement or
the Merger in a manner adverse to Gillette, and an Alternative Transaction is
consummated on or prior to the second anniversary of the date of termination, or
(iii) by Gillette or Duracell, because of the failure to obtain the requisite
vote for approval of the Merger Agreement by the stockholders of Duracell by
March 31, 1997, and a bona fide Alternative Transaction is publicly commenced,
publicly disclosed, publicly proposed or publicly communicated to Duracell at
any time on or prior to the date of the Duracell Special Meeting and there is
consummated an Alternative Transaction (whether or not the same as the
transaction so commenced, disclosed, proposed or
 
                                        6

communicated on or prior to the date of the Duracell Special Meeting) on or
prior to the second anniversary of the date of termination. See "The
Merger -- Fees and Expenses."
 
LISTING
 
     It is a condition to the Merger that the shares of Gillette Common Stock to
be issued in the Merger be approved for listing on the NYSE, subject to official
notice of issuance.
 
DIVIDENDS
 
     Duracell will pay its regular quarterly cash dividend of $.29 per share of
Duracell Common Stock in the fourth calendar quarter of 1996. Gillette will pay
its regular quarterly cash dividends of $.18 per share of Gillette Common Stock
and $12.0575 per share of ESOP Preferred Stock in the fourth calendar quarter of
1996. Following the Merger, it is the current intention of the Board of
Directors of Gillette to declare dividends on the Gillette Stock initially in
these amounts. Future dividends will be determined by Gillette's Board of
Directors in light of the earnings and financial condition of Gillette and its
subsidiaries and other factors. See "Comparative Per Share Prices and
Dividends."
 
APPRAISAL RIGHTS
 
     Under the General Corporation Law of the State of Delaware, the holders of
Duracell Common Stock and Gillette Stock are not entitled to any appraisal
rights with respect to the Merger. See "The Merger -- Appraisal Rights."
 
GOVERNMENTAL NOTIFICATIONS AND APPROVALS
 
     Prior to consummating the Merger, Gillette and Duracell must provide
notifications to, or obtain approvals from, U.S. federal antitrust authorities,
the Commission of the European Communities and competition and other authorities
in certain other foreign jurisdictions in which Gillette or Duracell currently
operate. See "The Merger -- Certain Legal Matters."
 
ANTICIPATED ACCOUNTING TREATMENT
 
     The Merger is expected to qualify as a "pooling of interests" for
accounting and financial reporting purposes. The receipt of a letter from each
of KPMG Peat Marwick LLP and Deloitte & Touche LLP, the certified independent
public accountants of Gillette and Duracell, respectively, confirming that the
Merger will qualify for "pooling of interests" accounting treatment is a
condition to consummation of the Merger.
 
STOCK OPTIONS
 
     At the Effective Time, each then outstanding option to purchase Duracell
Common Stock granted under the Stock Option Plan for Key Employees of Duracell
and the Duracell Shares Plan (collectively the "Duracell Stock Option Plans")
will be deemed assumed by Gillette and will be deemed to constitute an option to
acquire shares of Gillette Common Stock. As of November 1, 1996, there were
outstanding options to acquire 1,001,057 shares of Duracell Common Stock under
the Stock Option Plan for Key Employees of Duracell and options to acquire
4,668,758 shares of Duracell Common Stock under the Duracell Shares Plan. See
"The Merger -- Effect on Stock Option and Employee Benefits Plans" and "The
Merger Agreement -- Terms of the Merger -- Stock Options."
 
OPINIONS OF FINANCIAL ADVISORS
 
     Each of Merrill Lynch, Pierce, Fenner & Smith Incorporated ("Merrill
Lynch") and J.P. Morgan Securities Inc. ("J.P. Morgan") delivered its written
opinion dated September 12, 1996 to the Board of Directors of Gillette that, as
of such date and based on and subject to the matters stated therein, the
consideration proposed to be paid by Gillette pursuant to the Merger was fair to
Gillette from a financial point of view.

     Morgan Stanley & Co. Incorporated ("Morgan Stanley") delivered its written
opinion dated September 12, 1996 to the Board of Directors of Duracell that, as
of such date and based on and subject to certain matters stated therein, the
Exchange Ratio was fair from a financial point of view to the holders of
Duracell Common Stock.
 
     For information on the assumptions made, matters considered and limits of
the review undertaken by Merrill Lynch, J.P. Morgan and Morgan Stanley, see "The
Merger -- Opinions of Gillette's Financial Advisors," and "-- Opinion of
Duracell's Financial Advisor." STOCKHOLDERS ARE URGED TO READ IN THEIR ENTIRETY
THE OPINIONS OF MERRILL LYNCH, J.P. MORGAN AND MORGAN STANLEY ATTACHED AS
ANNEXES B, C AND D, RESPECTIVELY, TO THIS JOINT PROXY STATEMENT/PROSPECTUS.
 
INTERESTS OF CERTAIN PERSONS IN THE MERGER
 
     The Merger Agreement provides for severance agreements with Duracell
officers providing for payments, depending upon the officer, of one or two times
annual base salary plus fiscal 1996 bonus in certain circumstances. The Merger
Agreement also provides for certain arrangements with respect to indemnification
and insurance arrangements for Duracell officers and directors. Duracell has
agreed to pay Kohlberg Kravis Roberts & Co., L.P. ("KKR") an advisory fee of $20
million upon consummation of the Merger. Henry R. Kravis, George R. Roberts,
Paul E. Raether and Scott M. Stuart, each of whom is a director of Duracell, are
affiliates of the entity that is the general partner of KKR, and the receipt of
the entire $20 million advisory fee payable to KKR upon consummation of the
Merger may therefore be attributable to each of such persons. At the Effective
Time any unvested options to acquire Duracell Common Stock will vest and become
exercisable. Following consummation of the Merger, Henry R. Kravis, who is
currently a director of Duracell, will be appointed to the Gillette Board of
Directors by the directors of Gillette. Gillette and the KKR Stockholders have
entered into a Registration Rights Agreement dated as of September 12, 1996 (the
"Registration Rights Agreement") pursuant to which the KKR Stockholders may
require Gillette, subject to the terms and conditions set forth therein, to
register the shares of Gillette Common Stock to be received by them in the
Merger for sale in accordance with the Securities Act. See "The
Merger -- Interests of Certain Persons in The Merger" and "Other
Agreements -- Registration Rights Agreement."
 
CERTAIN UNITED STATES FEDERAL INCOME TAX CONSEQUENCES
 
     It is expected that the Merger will constitute a reorganization for United
States federal income tax purposes and, accordingly, that no gain or loss will
be recognized for United States federal income tax purposes by holders of
Duracell Common Stock upon the conversion of Duracell Common Stock into Gillette
Common Stock in the Merger (except with respect to any cash received in lieu of
a fractional share interest in Gillette Common Stock). The obligations of
Gillette and Duracell to consummate the Merger are conditioned on the receipt by
Gillette of an opinion from Ropes & Gray, its counsel, and the receipt by
Duracell of an opinion from Simpson Thacher and Bartlett, its counsel, that the
Merger constitutes a reorganization under Section 368 of the Internal Revenue
Code of 1986, as amended. See "The Merger -- Certain United States Federal
Income Tax Consequences." Duracell stockholders are urged to consult their own
tax advisors as to the specific tax consequences to them of the Merger.
 
                       COMPARATIVE RIGHTS OF STOCKHOLDERS
 
     The rights of stockholders of Duracell currently are governed by Delaware
law, Duracell's Certificate of Incorporation and Duracell's By-Laws. Upon
consummation of the Merger, stockholders of Duracell will become stockholders of
Gillette, which is also a Delaware corporation, and their rights as stockholders
of Gillette will be governed by Delaware law, Gillette's Certificate of
Incorporation and Gillette's By-Laws. For a discussion of various differences
between the rights of stockholders of Duracell and the rights of stockholders of
Gillette, see "Comparative Rights of Stockholders."

              SELECTED HISTORICAL AND PRO FORMA FINANCIAL DATA AND
                           COMPARATIVE PER SHARE DATA
 
     The following selected historical financial data of Gillette and Duracell
have been derived from their respective historical audited and unaudited
consolidated financial statements and should be read in conjunction with such
consolidated financial statements and the notes thereto that are incorporated
herein by reference. The selected pro forma combined financial data of Gillette
and Duracell have been derived from the unaudited pro forma condensed combined
financial statements and should be read in conjunction with such pro forma
condensed combined financial statements and the notes thereto included elsewhere
in this Joint Proxy Statement/Prospectus.
 
     The pro forma financial information does not purport to represent what
Gillette's financial position or results of operations would have actually been
had the Merger occurred at the beginning of the earliest period presented or to
project Gillette's financial position or results of operations for any future
date or period. It does not include any one-time, nonrecurring Merger-related
costs, nor does it incorporate any benefits from any potential cost savings or
synergies following the Merger.
 
     The unaudited pro forma condensed combined statements of operations combine
Gillette's historical results for the nine months ended September 30, 1996 and
September 30, 1995 and the years ended December 31, 1995, 1994 and 1993 with
Duracell's historical results for the nine months ended September 30, 1996 and
September 30, 1995, and the twelve months ended December 31, 1995, June 30, 1994
and June 30, 1993, respectively, giving the effect to the Merger as if it had
occurred on January 1, 1993. The unaudited pro forma condensed combined balance
sheet combines Gillette's and Duracell's consolidated condensed balance sheets
as of September 30, 1996, giving effect to the Merger as if it had occurred on
September 30, 1996.
 
     Gillette has a fiscal year ending December 31, and Duracell has a fiscal
year ending June 30. Accordingly, the unaudited pro forma condensed combined
financial statements for the year ended December 31, 1995 include Duracell's
financial statements conformed to Gillette's fiscal year end.
 
     The selected historical financial information as of September 30, 1996 and
for the nine months ended September 30, 1996 and 1995 has been derived from
audited and unaudited consolidated financial statements. Such unaudited
information reflects all adjustments (consisting only of normal, recurring
adjustments) necessary for the fair presentation of the financial condition as
of that date and the results of operations for those unaudited interim periods
for each of Gillette and Duracell. The results of operations for those interim
periods are not necessarily indicative of the results to be expected for the
entire year.
 
     As permitted by Commission regulations, Duracell's six-month period ended
December 31, 1994 has been omitted from the unaudited pro forma condensed
combined statements of operations. Duracell's Sales, Profit From Operations and
Net Income were $1,222.3 million, $287.0 million and $164.1 million,
respectively, for such six-month period. Duracell's Dividends Paid Per Common
Share during such six-month period amounted to $.44.

(1) It is estimated that Merger-related costs of approximately $340.0 million
    will be incurred for restructuring programs, other unusual and nonrecurring
    items, and direct costs of the Merger, consisting primarily of transaction
    costs for investment bankers fees, attorneys, accountants, financial
    printing and other related charges.
 
    Direct costs of the Merger are estimated at approximately $65.0 million. The
    pro forma condensed combined balance sheet gives effect to direct costs of
    the Merger as if they had been incurred as of September 30, 1996, but the
    pro forma condensed combined statements of operations do not give effect to
    such expenses.
 
(2) In 1993, realignment expenses for Gillette and restructuring charges for
    Duracell reduced Profit From Operations by $328 million, Income Before
    Accounting Changes by $211 million, and Income Per Common Share Before
    Accounting Changes by $.39.
 
(3) The pro forma combined dividends paid per Common Share are not necessarily
    indicative of dividends to be paid in future periods. It is the current
    intention of the Gillette Board of Directors to declare quarterly cash
    dividends following the Merger initially in the amount of $.18 per share of
    Gillette Common Stock. Future dividends will be determined by Gillette's
    Board of Directors in light of the earnings and financial condition of
    Gillette and its subsidiaries and other factors. See "Comparative Per Share
    Prices and Dividends -- Post-Merger Dividend Policy."
 
(4) The calculation of Income Per Common Share uses the weighted average number
    of common shares outstanding and excludes common share equivalents.

     The following table sets forth certain historical per share data of
Gillette and Duracell and combined per share data on an unaudited pro forma
basis after giving effect to the Merger as if it had occurred on January 1, 1993
on a pooling-of-interests basis assuming that .904 shares of Gillette Common
Stock were issued in exchange for each share of Duracell Common Stock
outstanding. This data should be read in conjunction with the selected
historical audited and unaudited financial data and the historical audited and
unaudited financial statements of Gillette and Duracell and the notes thereto
that are incorporated herein by reference. The selected pro forma combined
financial information of Gillette and Duracell is derived from the unaudited pro
forma condensed combined financial statements and should be read in conjunction
with such unaudited pro forma statements and notes thereto included elsewhere in
this Joint Proxy Statement/Prospectus. The unaudited pro forma information is
presented for illustrative purposes only and is not necessarily indicative of
the combined financial position or results of operations of future periods or
the results that actually would have been realized had Gillette and Duracell
been a single entity during the periods presented.

- ---------------
(1) Information is for the years ended June 30, 1994 and June 30, 1993 in the
    case of Duracell Historical Per Common Share data.
(2) In 1993, realignment expenses for Gillette and restructuring charges for
    Duracell reduced Income Per Common Share Before Accounting Changes by $.37
    and $.40, respectively, and by $.39 on a Pro Forma Combined -- Per Gillette
    Common Share basis.
(3) Historical Book Value Per Common Share is computed by dividing stockholders'
    equity for Gillette and Duracell by the number of shares of common stock
    outstanding at the end of each period for Gillette and Duracell,
    respectively. Pro Forma Book Value Per Common Share is computed by dividing
    pro forma stockholders' equity by the pro forma number of shares of common
    stock outstanding at the end of the period.
(4) The pro forma combined per share data combines financial information of
    Gillette for the fiscal years ended December 31, 1995, 1994 and 1993 and the
    nine months ended September 30, 1996 and 1995 with the financial information
    of Duracell for the twelve months ended December 31, 1995, June 30, 1994 and
    June 30, 1993 and the nine months ended September 30, 1996 and 1995,
    respectively. Gillette has a fiscal year ending December 31, and Duracell
    has a fiscal year ending June 30. Accordingly, the pro forma combined per
    share data for the year ended December 31, 1995 include Duracell's financial
    information conformed to Gillette's fiscal year end.
(5) It is estimated that Merger-related costs of approximately $340.0 million
    will be incurred for restructuring programs, other unusual and nonrecurring
    items, and direct costs of the Merger, consisting primarily of transaction
    costs for investment bankers fees, attorneys, accountants, financial
    printing, and other related charges. Direct costs of the Merger are
    estimated at approximately $65.0 million. The pro forma condensed combined
    balance sheet gives effect to direct costs of the Merger as if they had been
    incurred as of September 30, 1996, but the pro forma condensed combined
    statements of operations do not give effect to such expenses. These expenses
    are not reflected in the pro forma combined per share data.

                                  RISK FACTORS
 
     STOCKHOLDERS OF GILLETTE, IN CONSIDERING WHETHER TO APPROVE THE GILLETTE
SHARE PROPOSAL, AND STOCKHOLDERS OF DURACELL, IN CONSIDERING WHETHER TO APPROVE
AND ADOPT THE DURACELL MERGER PROPOSAL, SHOULD CONSIDER THE FOLLOWING MATTERS.
THESE MATTERS SHOULD BE CONSIDERED IN CONJUNCTION WITH THE OTHER INFORMATION
INCLUDED AND INCORPORATED BY REFERENCE IN THIS JOINT PROXY STATEMENT/PROSPECTUS.
 
     FIXED EXCHANGE RATIO DESPITE POTENTIAL CHANGES IN STOCK PRICES.  The
Exchange Ratio is a fixed ratio and will not be adjusted in the event of any
increases or decreases in the price of either Gillette Common Stock or Duracell
Common Stock. The price of Gillette Common Stock at the Effective Time may vary
from its price at the date of this Joint Proxy Statement/Prospectus and at the
date of the Special Meetings. Such variations may be the result of changes in
the business, operations or prospects of Gillette or Duracell, market
assessments of the likelihood that the Merger will be consummated, the timing
thereof and the prospects of the Merger and post-Merger operations, regulatory
considerations, general market and economic conditions and other factors.
Because the Effective Time may occur at a date later than the Special Meetings,
there can be no assurance that the price of Gillette Common Stock on the date of
the Special Meetings will be indicative of its price at the Effective Time. The
Merger Agreement provides that the Effective Time will occur as soon as
practicable following the Special Meetings and the satisfaction or waiver of the
other conditions set forth in the Merger Agreement. Stockholders of Gillette and
Duracell are urged to obtain current market quotations for Gillette Common Stock
and Duracell Common Stock. See "The Merger Agreement -- Terms of the Merger."
 
     NONREALIZATION OF SYNERGIES.  The Merger involves the integration of two
companies that have previously operated independently. No assurance can be given
that Gillette will integrate the respective operations of Gillette and Duracell
without encountering difficulties or experiencing the loss of key Duracell
personnel or that the benefits expected from such integration will be realized.
In addition, there can be no assurance that Gillette will realize anticipated
synergies from the Merger. See "The Merger -- Recommendation of the Board of
Directors of Gillette; Reasons for the Merger."
 
     CERTAIN RISKS INHERENT IN INTERNATIONAL BUSINESSES.  The financial
condition and results of operations of each of Gillette and Duracell may be
adversely affected when one or more of the global markets in which Gillette or
Duracell competes is affected by variations in political, economic or other
factors, such as exchange rates, inflation rates, recessionary or expansive
trends, tax changes, legal and regulatory changes or other external factors over
which neither Gillette nor Duracell has control.
 
     FORWARD-LOOKING STATEMENTS.  Certain statements made or incorporated by
reference in this Joint Proxy Statement/Prospectus are forward-looking,
including without limitation statements with respect to the expected financial
impact and other aspects of the proposed Merger and the future financial
condition or results of operations of Duracell and Gillette. Forward looking
statements made or incorporated by reference herein are not guarantees of future
performance and are subject to risks and uncertainties that could cause actual
results to differ materially. In addition to the factors discussed above under
"-- Nonrealization of Synergies" and "-- Certain Risks Inherent in International
Businesses," the following are some of the factors that could cause actual
results to differ materially from those in the forward-looking statements: the
pattern of sales, including variations in sales volume within a period, which
makes forward-looking statements about sales and earnings difficult and may
result in variances of actual results from those contained in statements made at
any time prior to the period's close; vigorous competition within Gillette's and
Duracell's product markets, including pricing and promotional, advertising or
other activities in order to preserve or gain market share, the timing of which
cannot be foreseen by Gillette or Duracell; the reliance on the development of
new products and the inherent risks associated with new product introductions,
including uncertainty of trade and customer acceptance and competitive reaction;
the costs and effects of unanticipated legal and administrative proceedings; the
impact of unusual items resulting from ongoing evaluations of business
strategies, asset valuations and organizational structure; and the fact that,
historically, over two-thirds of Gillette's sales and approximately half of
Duracell's sales have been made outside the United States, making
forward-looking statements more difficult.

                                  INTRODUCTION
 
     This Joint Proxy Statement/Prospectus is being furnished to the
stockholders of Gillette in connection with the solicitation of proxies by the
Board of Directors of Gillette for use at a Special Meeting of Stockholders of
Gillette to be held at the Sheraton Boston Hotel, 39 Dalton Street, Boston,
Massachusetts on December 30, 1996, at 10:00 a.m., and at any and all
adjournments or postponements thereof. This Joint Proxy Statement/Prospectus
also constitutes the Prospectus of Gillette with respect to the issuance of
shares of Gillette Common Stock in the Merger, as described below.
 
     This Joint Proxy Statement/Prospectus is also being furnished to the
stockholders of Duracell in connection with the solicitation of proxies by the
Board of Directors of Duracell for use at a Special Meeting of Stockholders of
Duracell to be held at the Ethan Allen Inn, 21 Lake Avenue Extension, Danbury,
Connecticut on December 30, 1996, at 10:00 a.m., and at any and all adjournments
or postponements thereof.
 
                            GILLETTE SPECIAL MEETING
 
PURPOSE OF THE GILLETTE SPECIAL MEETING
 
     At the Gillette Special Meeting, holders of Gillette Stock will consider
and vote upon the Gillette Share Proposal, which provides for the issuance of
Gillette Common Stock in connection with the Merger, pursuant to which (i)
Duracell will become a wholly-owned subsidiary of Gillette and (ii) each
outstanding share of Duracell Common Stock (other than shares owned by Duracell
as treasury stock or by its subsidiaries or by Gillette or its subsidiaries, all
of which shall be canceled) will be converted into the right to receive 0.904
shares of Gillette Common Stock. Although Delaware law and the Certificate of
Incorporation of Gillette do not require Gillette to obtain stockholder approval
of the Merger, the rules of the NYSE require Gillette to obtain stockholder
approval of the issuance of such shares due to the number of authorized but
unissued shares of Gillette Common Stock expected to be issued in the Merger.
Holders of Gillette Stock may also consider and vote upon matters incident to
the conduct of the Gillette Special Meeting.
 
     Based upon the Exchange Ratio and the number of shares of Duracell Common
Stock and of options to purchase Duracell Common Stock under the Duracell Stock
Option Plans outstanding at November 1, 1996, Gillette would issue approximately
109,026,398 shares of Gillette Common Stock to Duracell stockholders in the
Merger and would assume options to purchase Duracell Common Stock which would be
converted into options to purchase approximately 5,125,513 shares of Gillette
Common Stock.
 
     THE BOARD OF DIRECTORS OF GILLETTE HAS APPROVED THE MERGER AND THE GILLETTE
SHARE PROPOSAL AND RECOMMENDS THAT GILLETTE STOCKHOLDERS VOTE FOR APPROVAL OF
THE GILLETTE SHARE PROPOSAL. SEE "THE MERGER -- BACKGROUND OF THE MERGER" AND
"RECOMMENDATION OF THE BOARD OF DIRECTORS OF GILLETTE; REASONS FOR THE MERGER."
 
RECORD DATE
 
     The Gillette Board of Directors has fixed the close of business on November
1, 1996 as the Gillette Record Date for determining holders entitled to notice
of and to vote at the Gillette Special Meeting.
 
     As of the Gillette Record Date, there were 446,148,579 shares of Gillette
Common Stock issued and outstanding, each of which entitles the holder thereof
to one vote, and 158,699 shares of ESOP Preferred Stock, each of which entitles
the holder thereof to 40 votes. The holders of Gillette Common Stock and ESOP
Preferred Stock vote together as one class.
 
QUORUM
 
     The presence in person or by properly executed proxy of holders of
one-third in interest of the issued and outstanding shares of Gillette Stock
entitled to vote is necessary to constitute a quorum at the Gillette Special
Meeting.
 
                                       15
<PAGE>   25
 
REQUIRED VOTE
 
     Under the rules of the NYSE the Gillette Share Proposal will require
approval by the affirmative vote of the holders of a majority of the votes cast
on this matter, provided that the total votes cast on this matter represent more
than 50% in interest of the votes entitled to be cast. As of the Gillette Record
Date, the directors and executive officers of Gillette and their affiliates
beneficially owned as a group approximately 11.3% of the outstanding shares of
Gillette Common Stock and approximately 0.1% of the outstanding shares of ESOP
Preferred Stock, representing in the aggregate approximately 11.2% of the voting
power of the outstanding Gillette Stock on such date.
 
VOTING RIGHTS; PROXIES
 
     All shares of Gillette Stock represented by properly executed proxies will,
unless such proxies have been previously revoked, be voted in accordance with
the instructions indicated in such proxies. IF NO INSTRUCTIONS ARE INDICATED,
SUCH SHARES OF GILLETTE STOCK WILL BE VOTED IN FAVOR OF THE GILLETTE SHARE
PROPOSAL. Gillette does not know of any matters other than as described in the
accompanying Notice of Special Meeting that are to come before the Gillette
Special Meeting. If any other matter or matters are properly presented for
action at the Gillette Special Meeting, the persons named in the enclosed form
of proxy and acting thereunder will have the discretion to vote on such matters
in accordance with their best judgment, unless such authorization is withheld. A
stockholder who has given a proxy may revoke it at any time prior to its
exercise by giving written notice thereof to Gillette's Transfer Agent, The
First National Bank of Boston, c/o Boston EquiServe, P.O. Box 1878, Boston,
Massachusetts 02105-9805, by signing and returning a later dated proxy, or by
voting in person at the Gillette Special Meeting. Accordingly, Gillette
stockholders who have executed and returned proxy cards in advance of the
Gillette Special Meeting may change their votes at any time prior to the vote on
the Gillette Share Proposal at the Gillette Special Meeting; however, mere
attendance at the Gillette Special Meeting will not in and of itself have the
effect of revoking the proxy.
 
     The enclosed proxy will also serve as a confidential voting instruction
with respect to Gillette's employees' savings plans, Employee Stock Ownership
Plan ("ESOP") and Global Employee Stock Ownership Plan ("GESOP"). If voting
instructions have not been received from a participant by December 20, 1996, the
shares allocated to such participant's account(s) and ESOP and GESOP shares that
have not been allocated to participant accounts will be voted on the issue in
proportion to the shares as to which voting instructions have been returned by
other participants of each respective plan.
 
     Votes cast by proxy or in person at the Gillette Special Meeting will be
tabulated by the election inspectors appointed for the meeting who will
determine whether or not a quorum is present. The election inspectors will count
shares represented by proxies that reflect abstentions and "broker non-votes"
(i.e., shares represented at the meeting held by brokers or nominees as to which
(i) instructions have not been received from the beneficial owners or persons
entitled to vote and (ii) the broker or nominee does not have the discretionary
voting power on a particular matter) only as shares that are present and
entitled to vote on the matter for purposes of determining the presence of a
quorum, but neither abstentions nor broker non-votes have any effect on the
outcome of voting on the matter.
 
SOLICITATION OF PROXIES
 
     Gillette will bear its own cost of solicitation of proxies. Brokerage
houses, fiduciaries, nominees and others will be reimbursed for their
out-of-pocket expenses in forwarding proxy materials to beneficial owners of
stock held in their names. Gillette has retained Georgeson & Company, Inc.
("Georgeson") to assist in the solicitation of proxies for the Gillette Special
Meeting at a fee estimated to be $20,000 plus reimbursement of out of pocket
expenses. Georgeson will be indemnified against certain liabilities and
expenses, including liabilities under federal securities laws.

     THE MATTER TO BE CONSIDERED AT THE GILLETTE SPECIAL MEETING IS OF GREAT
IMPORTANCE TO THE STOCKHOLDERS OF GILLETTE. ACCORDINGLY, STOCKHOLDERS ARE URGED

STATEMENT/PROSPECTUS, AND TO COMPLETE, DATE, SIGN AND PROMPTLY RETURN THE
ENCLOSED PROXY IN THE ENCLOSED POSTAGE-PAID ENVELOPE.

"-- RECOMMENDATION OF THE BOARD OF DIRECTORS OF DURACELL; REASONS FOR THE
MERGER"; AND " -- INTERESTS OF CERTAIN PERSONS IN THE MERGER."
 
RECORD DATE
 
     The Duracell Board of Directors has fixed the close of business on November
1, 1996 as the Duracell Record Date for determining holders entitled to notice
of and to vote at the Duracell Special Meeting.
 
QUORUM
 
     The presence in person or by properly executed proxy of holders of a
majority of the issued and outstanding shares of Duracell Common Stock is
necessary to constitute a quorum at the Duracell Special Meeting.
 
REQUIRED VOTE
 
     Approval of the Duracell Merger Proposal requires the affirmative vote of
the holders of a majority of the outstanding shares of Duracell Common Stock.
Abstentions and broker nonvotes will have the effect of votes against approval
of the Duracell Merger Proposal. Holders of approximately 34% of the Duracell
Common Stock outstanding as of the date of the Merger Agreement have agreed to
vote in favor of the Duracell Merger Proposal and have granted Merger Sub an
irrevocable proxy to vote their shares of Duracell Common Stock in accordance
therewith. See "Other Agreements -- Stockholders Agreement." As of the Duracell
Record Date, the directors and executive officers of Duracell and their
affiliates (excluding the KKR Stockholders) beneficially owned as a group
approximately 1.4% of the outstanding shares of Duracell Common Stock.
 
VOTING RIGHTS; PROXIES
 
     As of the Duracell Record Date, there were 120,604,423 shares of Duracell
Common Stock issued and outstanding, each of which entitles the holder thereof
to one vote. All shares of Duracell Common Stock represented by properly
executed proxies will, unless such proxies have been previously revoked, be
voted in accordance with the instructions indicated in such proxies. IF NO
INSTRUCTIONS ARE INDICATED, SUCH SHARES OF DURACELL COMMON STOCK WILL BE VOTED
IN FAVOR OF APPROVAL AND ADOPTION OF THE MERGER AGREEMENT. Duracell does not
know of any matters other than as described in the accompanying Notice of
Special Meeting that are to come before the Duracell Special Meeting. If any
other matter or matters are properly presented for action at the Duracell
Special Meeting, the persons named in the enclosed form of proxy and acting
thereunder will have the discretion to vote on such matters in accordance with
their best judgment, unless such authorization is withheld. A stockholder giving
a proxy pursuant to this proxy solicitation may revoke it at any time before it
is exercised by giving a subsequent proxy, by delivering to The First National
Bank of Boston, c/o Boston EquiServe, P.O. Box 1878, Boston, Massachusetts
02105-9805 a written notice of revocation prior to the voting of the proxy at
the Special Meeting, or by attending the Special Meeting and informing the
Secretary of Duracell in writing that such stockholder wishes to vote his or her
shares in person. However, mere attendance at the Duracell Special Meeting will
not in and of itself have the effect of revoking the proxy.

     Votes cast by proxy or in person at the Duracell Special Meeting will be
tabulated by the election inspectors appointed for the meeting who will
determine whether or not a quorum is present. The election inspectors will treat
abstentions as shares that are present and entitled to vote for purposes of
determining the presence of a quorum and not voted in favor of the Duracell
Merger Proposal. If a broker indicates on the proxy that it does not have
discretionary authority as to certain shares to vote on a particular matter,
those shares will not be considered as shares of Duracell Common Stock voted in
favor of the Duracell Merger Proposal.
 
SOLICITATION OF PROXIES
 
     Duracell will bear its own cost of solicitation of proxies. Brokerage
houses, fiduciaries, nominees and others will be reimbursed for their
out-of-pocket expenses in forwarding proxy materials to beneficial owners of
stock held in their names. Duracell has retained MacKenzie Partners, Inc.
("MacKenzie") to assist in the solicitation of proxies for the Duracell Special
Meeting at a fee estimated to be $6,000 plus reimbursement of out of pocket
expenses. MacKenzie will be indemnified against certain liabilities and
expenses, including liabilities under federal securities laws.
 
     THE MATTER TO BE CONSIDERED AT THE DURACELL SPECIAL MEETING IS OF GREAT
IMPORTANCE TO THE STOCKHOLDERS OF DURACELL. ACCORDINGLY, STOCKHOLDERS ARE URGED
TO READ AND CAREFULLY CONSIDER THE INFORMATION PRESENTED IN THIS PROXY
STATEMENT, AND TO COMPLETE, DATE, SIGN AND PROMPTLY RETURN THE ENCLOSED PROXY IN
THE ENCLOSED POSTAGE-PAID ENVELOPE.

                                   THE MERGER
 
GENERAL
 
     The Merger Agreement provides that the Merger will be consummated if the
approvals of the Gillette and Duracell stockholders required therefor are
obtained and all other conditions to the Merger are satisfied or waived. Upon
consummation of the Merger, Merger Sub will be merged with and into Duracell,
the separate corporate existence of Merger Sub shall cease, and Duracell shall
continue as the surviving corporation (the "Surviving Corporation") and a
wholly-owned subsidiary of Gillette. Pursuant to the Merger, each outstanding
share of Duracell Common Stock (other than shares owned by Duracell as treasury
stock or by its subsidiaries or by Gillette or its subsidiaries, all of which
shall be canceled and retired) will be converted into the right to receive 0.904
shares of Gillette Common Stock.
 
     Based upon the outstanding shares of Gillette and Duracell as of November
1, 1996 and the Exchange Ratio, the stockholders of Duracell immediately prior
to the consummation of the Merger would own approximately 20% of the outstanding
Gillette Common Stock following consummation of the Merger. Such percentage
could change depending upon whether shares of Gillette Common Stock and Duracell
Common Stock issuable upon exercise of outstanding Gillette and Duracell stock
options or other rights or upon conversion of ESOP Preferred Stock are issued.
 
EFFECTIVE TIME
 
     Consummation of the Merger will occur upon the filing of a certificate of
merger, together with any required related certificates, with the Secretary of
State of the State of Delaware (the "Certificate of Merger"). The Merger
Agreement provides that filing of the Certificate of Merger will occur as
promptly as practicable (and in any event within two business days) after the
satisfaction or waiver of all conditions to the closing of the Merger. The
Merger Agreement may be terminated by either party if the Merger shall not have
been consummated on or before March 31, 1997 (provided that such right to
terminate the Merger Agreement shall 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). The
Merger Agreement may also be terminated under certain other circumstances. See
"The Merger Agreement -- Conditions to the Merger" and "-- Termination."
 
CONVERSION OF SHARES; PROCEDURES FOR EXCHANGE OF CERTIFICATES
 
     The conversion of Duracell Common Stock into the right to receive Gillette
Common Stock at the Exchange Ratio will occur automatically at the Effective
Time.
 
     The Merger Agreement requires Gillette to supply at or prior to the
Effective Time, to The First National Bank of Boston or such other bank or trust
company as shall be designated by Gillette (the "Exchange Agent"), in trust for
the benefit of the holders of Duracell Common Stock, certificates evidencing the
Gillette Common Stock issuable in exchange for such Duracell Common Stock.
 
     As soon as reasonably practicable after the Effective Time, a transmittal
letter and instructions will be mailed by the Exchange Agent to each stockholder
of Duracell informing such stockholder of the procedures to follow in forwarding
stock certificates representing Duracell Common Stock to the Exchange Agent.
Upon receipt of such Duracell stock certificates together with such transmittal
letter, duly executed, and such other customary documents as may be required
pursuant to such instructions, the Exchange Agent will deliver full shares of
Gillette Common Stock to such stockholder and cash in lieu of fractional shares
pursuant to the terms of the Merger Agreement and in accordance with the
transmittal letter, together with any dividends or other distributions to which
such stockholder is entitled.
 
     If any issuance of shares of Gillette Common Stock in exchange for shares
of Duracell Common Stock is to be made to a person other than the Duracell
stockholder in whose name the certificate is registered at the Effective Time,
it will be a condition of such exchange that the certificate so surrendered be
properly endorsed or otherwise in proper form for transfer and that the Duracell
stockholder requesting such issuance either pay
 
                                       20
<PAGE>   30
 
any transfer or other tax required or establish to the satisfaction of Gillette
that such tax has been paid or is not payable.
 
     After the Effective Time, there will be no further transfers of Duracell
Common Stock on the stock transfer books of Duracell. If a certificate
representing Duracell Common Stock is presented for transfer, it will be
canceled and a certificate representing the appropriate number of full shares of
Gillette Common Stock and cash in lieu of fractional shares and any dividends
and distributions will be issued in exchange therefor.
 
     After the Effective Time and until surrendered, shares of Duracell Common
Stock will be deemed for all corporate purposes, other than the payment of
dividends and distributions and subject to the right to receive cash in lieu of
fractional shares, to evidence ownership of the number of full shares of
Gillette Common Stock which such shares of Duracell Common Stock represented the
right to receive at the Effective Time. No dividends or other distributions
declared or made after the Effective Time with respect to Gillette Common Stock
with a record date after the Effective Time will be paid to the holders of any
certificates for shares of Duracell Common Stock until such certificates are
surrendered. Upon surrender of such certificates, all such declared dividends
and distributions which shall have become payable with respect to such Gillette
Common Stock in respect of a record date after the Effective Time will be paid
to the holder of record of the full shares of Gillette Common Stock represented
by the certificate issued in exchange therefor, without interest. See "The
Merger Agreement -- Exchange of Certificates."
 
     DURACELL STOCKHOLDERS SHOULD NOT FORWARD STOCK CERTIFICATES TO THE EXCHANGE
AGENT UNTIL THEY HAVE RECEIVED TRANSMITTAL LETTERS. DURACELL STOCKHOLDERS SHOULD
NOT RETURN STOCK CERTIFICATES WITH THE ENCLOSED PROXY.

BACKGROUND OF THE MERGER
 
     In August 1995, Gillette formed a project team, comprised of its employees
and representatives of J.P. Morgan and Merrill Lynch, to screen target companies
for a potential acquisition by Gillette. In August and September 1995, the
project team conducted the first phase of the screening process. Starting from a
pool of approximately 7,500 consumer product companies, the project team
narrowed its focus to 44 companies. After further screening and analysis, this
number was further reduced to 20 companies.
 
     On September 22, 1995, the project team made a presentation to Gillette
Chairman and Chief Executive Officer Alfred M. Zeien and other senior management
of Gillette to report on the first phase of their screening, and recommended
eight companies as potential acquisition candidates. Senior management
authorized the project team to proceed with further analysis of seven of the
eight proposed companies.
 
     On November 15, 1995, the project team made a presentation to Mr. Zeien and
other senior management of Gillette based on this further analysis. It was
concluded at this meeting that Duracell was the leading candidate. After this
meeting and another meeting on December 6, 1995 among members of the project
team and Gillette senior management, the project team undertook to develop a
strategy for Mr. Zeien to approach Henry R. Kravis to initiate negotiations for
an acquisition. Mr. Kravis is a director of Duracell, a general partner of KKR
Associates and an affiliate of Kohlberg Kravis Roberts & Co., L.P. ("KKR"). KKR
provides certain advisory services to Duracell, and KKR Associates is the
general partner of the two partnerships that own collectively approximately 34%
of the outstanding Duracell Common Stock.
 
     On December 14, 1995, at a meeting of the Gillette Board of Directors,
Duracell was identified as a possible acquisition candidate and it was the sense
of the meeting that Mr. Zeien contact Mr. Kravis to discuss a possible
acquisition of Duracell in a stock-for-stock merger.
 
     On January 19, 1996 and February 6, 1996, Mr. Zeien met with Mr. Kravis and
Scott M. Stuart, another director of Duracell, general partner of KKR Associates
and affiliate of KKR, to discuss Gillette's interest in acquiring Duracell. At
those meetings, the parties discussed the potential benefits of such an
acquisition, but determined that there was a substantial difference in views as
to the appropriate values to be placed on the stock of both companies.
 
     On February 15, 1996, at a meeting of the Board of Directors of Gillette,
Mr. Zeien discussed the meetings with Mr. Kravis. Due to the substantial
difference between the views of Gillette and KKR on the relative values of
Gillette and Duracell, it was the sense of the Board of Directors that no
further action should be taken at that time.
 
     Following this meeting, the Gillette project team was instructed to
reconsider other potential targets for acquisition.
 
     On April 10, 1996, the Gillette project team presented updated information
and analyses to Mr. Zeien and other senior management of Gillette and advised
them that Duracell remained the preferred acquisition candidate.
 
     On June 20, 1996 Mr. Zeien briefly evaluated the possible acquisition of
Duracell for the Gillette Board of Directors and the change in the stock prices
of Gillette and Duracell since January. Gillette's stock closed at $54 1/4 on
January 19, 1996 and $58 7/8 on June 19, 1996, while Duracell's stock closed at
$45 1/8 on January 19, 1996 and $43 3/8 on June 19, 1996. It was the sense of
the meeting that Mr. Zeien resume discussions with Mr. Kravis.
 
     On July 10, 1996, Mr. Zeien and, on behalf of Duracell, Messrs. Kravis and
Stuart, directors of Duracell, met again in Boston to discuss a potential
acquisition of Duracell, at which point there continued to be a substantial
difference in views as to the appropriate values to be placed on the stock of
both companies.
 
     On July 12, 1996, representatives of KKR advised members of senior
management of Duracell for the first time of the discussions between Messrs.
Kravis and Zeien. Morgan Stanley was then retained as a financial advisor to
Duracell.
 
                                       22
<PAGE>   32
 
     On July 18, 1996, the project team made a presentation to the Gillette
Board of Directors concerning a potential acquisition of Duracell. It was the
sense of the meeting that Mr. Zeien continue his discussions if KKR made a
proposal which Mr. Zeien thought would serve as a basis for negotiations.
 
     Commencing July 29, 1996, Messrs. Zeien and Kravis had numerous telephone
conversations discussing exchange ratios for a stock for stock exchange. In
those discussions, Mr. Kravis stated that KKR believed that one share of
Gillette Common Stock should be exchanged for each share of Duracell Common
Stock, and Mr. Zeien raised the possibility of an exchange ratio of .875 shares
of Gillette stock for each Duracell share.
 
     On August 22, 1996, the Duracell Board of Directors met. They were briefed
on the discussions to date with Gillette and received a presentation by Morgan
Stanley on the possible combination with Gillette and by outside legal counsel
on their duties in considering such a combination. The Duracell Board concluded
that an exchange ratio of .875 was inadequate.
 
     Telephone negotiations between Mr. Zeien and Mr. Kravis continued. On
August 29, 1996, in a telephone conversation, Messrs. Zeien and Kravis agreed to
recommend to the Boards of Directors of Gillette and Duracell, respectively,
subject to the negotiation of mutually satisfactory definitive agreements, the
acquisition of Duracell by Gillette in a stock transaction at an exchange ratio
of 0.904 shares of Gillette Common Stock for each share of Duracell Common
Stock.
 
     On August 30, 1996, Duracell and Gillette executed a confidentiality letter
with respect to the exchange of nonpublic information between the companies and
certain other matters, and KKR agreed to be bound by the obligations in the
letter with respect to confidentiality and certain other matters.
 
     On September 3, 1996, Gillette representatives met in New York with
Duracell senior management to gather information concerning Duracell's business.
Financial advisors for Gillette and Duracell were present.
 
     On September 4, 1996, Duracell and KKR representatives met in Boston with
Gillette senior management to gather information concerning Gillette's business.
Financial advisors for Gillette and Duracell were present.
 
     During the period from September 5, 1996 through the announcement of the
Merger on September 12, 1996, representatives of Gillette, Duracell and KKR and
their respective financial advisors and legal counsel were in frequent contact
to negotiate the terms of the Merger Agreement, the Stockholders Agreement and
the Registration Rights Agreement. The principal areas of negotiations included
the representations and warranties to be made by Duracell and Gillette in the
Merger Agreement; the business covenants to be made by Duracell in the Merger
Agreement; the conditions required for a termination of the Merger Agreement;
the triggering events for the payment of a fee, and the amount thereof, in the
event of certain terminations of the Merger Agreement; severance arrangements
for Duracell employees; and the amount of the investment banking and advisory
fees to be paid by Duracell.
 
     On the morning of September 12, 1996, the Board of Directors of Duracell
met to consider the proposed Merger. Members of Duracell's senior management,
Duracell's legal advisors and its financial advisors made presentations and
reviewed the matters set forth under "-- Recommendation of the Board of
Directors of Duracell; Reasons for the Merger." The terms of the Merger
Agreement, Stockholders Agreement and Registration Rights Agreement were
reviewed with the directors. Morgan Stanley rendered its oral opinion, confirmed
by a subsequent written opinion dated September 12, 1996 that, as of such date,
the Exchange Ratio was fair from a financial point of view to stockholders of
Duracell. After discussion and consideration, the Duracell Board of Directors
voted unanimously to approve the Merger, the Merger Agreement and related
documents for the transaction. Thereafter, the Duracell Board of Directors
approved the aggregate $30 million investment banking and advisory fees to be
paid by Duracell in connection with the Merger. Prior to taking such action, the
Duracell Board was advised that (i) the investment banking and advisory fees
were disclosed to and discussed with Gillette only after the principal terms of
the Merger, including the Exchange Ratio, were agreed upon by the parties and
(ii) the Gillette Board of Directors had taken the first two votes discussed in
the next paragraph. In addition, prior to taking such action the directors were
advised by special counsel to the directors who are not affiliated with KKR or
members of management that the aggregate investment banking and advisory fees
were, on a percentage basis, approximately 0.39% of the value of the
transaction, which was
 
                                       23
<PAGE>   33
 
within a range of fees of approximately 0.15% to approximately 0.80% paid to
advisors to acquired companies in recent large transactions.
 
     Also on the morning of September 12, 1996, the Board of Directors of
Gillette met to consider the proposed Merger. Representatives of Gillette's
senior management, Gillette's legal advisors and its financial advisors made
presentations and reviewed the matters set forth under "-- Recommendation of the
Board of Directors of Gillette; Reasons for the Merger." The terms of the Merger
Agreement, Stockholders Agreement and Registration Rights Agreement were
reviewed with the directors. Merrill Lynch and J.P. Morgan rendered their oral
opinions, confirmed by subsequent written opinions dated September 12, 1996
that, as of such date, the consideration to be paid by Gillette pursuant to the
Merger was fair to Gillette from a financial point of view. After discussion and
consideration, the Board of Directors of Gillette adopted two votes with respect
to the Merger. In the first vote which was unanimous, the Board voted to approve
the Merger, the Merger Agreement and related documents for the transaction,
provided that the investment banking and advisory fees to be paid by Duracell
were reduced to $18 million. In the second vote as to which two directors
abstained, the Board voted to approve the Merger, the Merger Agreement and
related documents for the transaction, without reduction in the amount of those
investment banking and advisory fees. These two votes were communicated to the
Duracell Board of Directors. After being informed by Duracell that the Duracell
Board of Directors had voted to approve the Merger Agreement without a reduction
in fees, a third vote was taken. Eleven of the twelve Gillette directors voted
to approve the Merger, the Merger Agreement and related documents, and one
director, Warren E. Buffett, abstained.
 
     Mr. Buffett advised the Board of Directors of Gillette that his abstention
did not relate to the Merger, which he favored, but he objected, as a matter of
principle, to the size of the investment banking and advisory fees payable by
Duracell which he believed to be excessive. He noted that some 80% of the
Duracell fees would effectively be borne by pre-Merger Gillette stockholders.
Mr. Buffett subsequently advised Gillette that he and his affiliates who hold
approximately 10.8% of the outstanding shares of Gillette Common Stock presently
intend to vote in favor of the Gillette Share Proposal.
 
     The Merger Agreement and other transaction documents were executed and at
approximately 10:30 a.m. Eastern time on September 12, 1996, the Merger was
publicly announced.
 
RECOMMENDATION OF THE BOARD OF DIRECTORS OF GILLETTE; REASONS FOR THE MERGER
 
     At its September 12, 1996 meeting, the Gillette Board of Directors
determined that the Merger is fair to Gillette and in the best interests of its
stockholders. Accordingly at such meeting, the Board of Directors of Gillette
approved the Merger Agreement.
 
     The determination of the Gillette Board was based upon consideration of a
number of factors. The following list includes all material factors considered
by the Gillette Board in its evaluation of the Merger:
 
 1. The desire of the Board to add a new core consumer product category to its
    business.
 
 2. The Board's conclusion that the Merger would further Gillette's mission of
    achieving and enhancing clear worldwide leadership in existing or new core
    consumer product categories.
 
 3. The appropriateness of Duracell's business to Gillette's business including
    the nature and size of its business, its global leadership, its
    well-recognized brand name, its excellent financial history, its potential
    for further geographic expansion, the compatibility of the respective
    business philosophies of Gillette and Duracell, and its technological
    leadership.
 
 4. The conclusion of the Gillette Board of Directors that Gillette could
    achieve synergistic benefits, including operating efficiencies and more
    rapid expansion utilizing Gillette's worldwide distribution capabilities.
    Gillette estimates the pre-tax amounts of synergies to be realized following
    the Merger to range from approximately $24 million in 1997 to approximately
    $116 million in 2001.
 
 5. The expected improvement in financial results as a result of the Merger
    beyond what Gillette could achieve on a stand-alone basis.
 
 6. The Board's receipt of the opinions of J. P. Morgan and Merrill Lynch that,
    as of September 12, 1996 and based on and subject to the matters stated
    therein, the consideration proposed to be paid by Gillette
 
                                       24
<PAGE>   34
 
    pursuant to the Merger was fair to Gillette from a financial point of view.
    The Gillette Board recognized that the value of such consideration, while
    within the range of values determined using a number of the analyses upon
    which such opinions were based, exceeded the range of values determined
    using certain of the other analyses upon which such opinions were based,
    including the "Comparable Acquisition Analysis" performed by Merrill Lynch
    with respect to certain selected battery product transactions and the
    "Public Trading Multiples Analysis" and "Relative Value Analysis Based on
    Selected Trading Multiples" performed by J.P. Morgan assuming no synergies.
    See "-- Opinions of Gillette's Financial Advisors."
 
 7. The Board's knowledge of the business, operations, properties, assets,
    financial condition, operating results and prospects of Gillette and
    Duracell.
 
 8. The current industry, economic and market conditions.
 
 9. The presentations by Gillette's management with respect to the acquisition
    of Duracell.
 
10. The terms of the Merger Agreement, the Stockholders Agreement and the
    Registration Rights Agreement.
 
11. The historical trading prices, dividend rates and trading activity for
    Duracell Common Stock and Gillette Common Stock.
 
12. The expected accounting treatment of the transaction as a pooling of
    interests.
 
13. The expected tax-free nature of the exchange.
 
     In view of the variety of factors considered in connection with its
evaluation of the Merger, the Gillette Board of Directors did not find it
practicable to and did not quantify or otherwise assign relative weights to the
specific factors considered in reaching its determination. In making its
determination, the Gillette Board of Directors also considered the risks and
likelihood of achieving the results discussed above.
 
     As discussed under "-- Background of the Merger," the Board of Directors of
Gillette also discussed the investment banking and advisory fees payable by
Duracell in connection with the Merger. The Gillette Board did not believe that
these fees were material in the context of the Merger and, although the Board
regarded the aggregate size of these fees to be a disadvantage, the Board
believed the anticipated advantages of the Merger outweighed this disadvantage.
The Gillette Board did not believe the fees constituted a risk of the Merger.
 
     THE GILLETTE BOARD OF DIRECTORS HAS APPROVED THE TERMS OF THE MERGER AND
RECOMMENDS THAT GILLETTE'S STOCKHOLDERS VOTE FOR THE GILLETTE SHARE PROPOSAL.
 
RECOMMENDATION OF THE BOARD OF DIRECTORS OF DURACELL; REASONS FOR THE MERGER
 
     At its September 12, 1996 meeting, the Duracell Board of Directors
determined that the Merger was fair to and in the best interests of Duracell and
its stockholders. Accordingly, at such meeting, the Board of Directors of
Duracell approved the Merger Agreement and directed that the Merger Agreement be
submitted to the holders of shares of Duracell Common Stock for approval and
adoption.
 
     The determination of the Duracell Board to approve the Merger Agreement was
based upon consideration of a number of factors. The following list includes all
material factors considered by the Duracell Board in its evaluation of the
Merger and the Merger Agreement:
 
          1. The opportunity for Duracell stockholders to participate as holders
     of Gillette Common Stock, in a larger, more diversified company, of which
     Duracell would be a significant part, and to participate in the value that
     may be generated through the combination of the two companies through their
     status as stockholders of Gillette;
 
          2. The Exchange Ratio negotiated with Gillette and the implied premium
     over the recent market price of Duracell Common Stock;
 
                                       25
<PAGE>   35
 
          3. The strategic and financial alternatives available to Duracell,
     including remaining an independent company;
 
          4. The Board's receipt of the written opinion of Morgan Stanley that,
     as of September 12, 1996 and based on and subject to certain matters stated
     therein, the Exchange Ratio was fair from a financial point of view to
     holders of Duracell Common Stock;
 
          5. The fact that the Merger is designed to be tax-free to Duracell's
     stockholders and is expected to be treated as a pooling of interests for
     accounting purposes;
 
          6. The Board's review of (i) the historical market prices of shares of
     Duracell Common Stock and Gillette Common Stock, (ii) the historical market
     prices of shares of Duracell Common Stock compared to the number of shares
     of Gillette Common Stock to be received in light of the proposed Exchange
     Ratio and (iii) the future rates of growth and price earning ratios which
     would be necessary for the market price of Duracell Common Stock to equal
     or exceed the market value of Gillette Common Stock being offered in the
     Merger;
 
          7. The Board's review of presentations by, and discussion of the terms
     and conditions of the Merger Agreement, the Stockholders Agreement and the
     Registration Rights Agreement with, senior executive officers of Duracell,
     representatives of its legal counsel and representatives of Morgan Stanley;
 
          8. Certain publicly available information with respect to the
     financial condition and results of operations of Gillette as well as
     presentations made by Morgan Stanley regarding the business, financial
     condition and prospects of Gillette; and
 
          9. The fact that, to the extent required by the fiduciary obligations
     of the Duracell Board, as determined by the Duracell Board after
     consultation with and based upon the written advice of its outside legal
     counsel, the Board may withdraw its recommendation and Duracell may
     terminate the Merger Agreement, subject, in certain circumstances, to the
     payment of a termination fee.
 
     In view of the wide variety of material factors considered in connection
with its evaluation of the Merger, the Board did not find it practicable to, and
did not, quantify or otherwise attempt to assign relative weights to the
specific factors considered in reaching its determination. In making its
determination, the Duracell Board of Directors also considered the risks and
likelihood of achieving the results discussed above. For a discussion of the
interests of certain members of Duracell's management and Board of Directors in
the Merger, see "-- Interests of Certain Persons in the Merger."
 
     Since January 1995, Duracell did not consider strategic combinations or
mergers with third parties other than Gillette. During the period that
discussions and negotiations were occurring with Gillette, Duracell did not
consider strategic combinations or mergers with third parties other than
Gillette, because Duracell believed that a combination with Gillette offered
Duracell stockholders the long-term strategic benefits of participating as
stockholders of Gillette in a combination of Duracell and Gillette (see
"-- Recommendation of the Board of Directors of Duracell; Reasons for the
Merger") and was advised by Morgan Stanley that, at any of the values proposed
by Gillette, there were no other likely parties. In addition, the
Confidentiality Agreement entered into by Duracell and Gillette on August 30,
1996 prohibited Duracell from soliciting other proposals between August 30, 1996
and September 12, 1996. In light of the foregoing, Duracell and its advisors
insisted upon provisions being included in the Merger Agreement which allow
Duracell to, among other things, consider unsolicited third-party acquisition
proposals, negotiate and discuss any such proposals, and terminate the Merger
Agreement, subject, in certain circumstances, to the payment of a termination
fee, if the Board of Directors of Duracell were to determine, in the exercise of
its fiduciary duties, to recommend an alternative acquisition proposal or to
withdraw its recommendation of the Merger. See "The Merger Agreement --
Termination." Since Duracell began discussions with Gillette, Duracell has not
received any unsolicited third-party acquisition proposals.
 
     Following the approval by the Duracell Board of Directors of the Merger,
the Merger Agreement and the related documents for the transaction, the Board
approved the aggregate $30 million investment banking and advisory fees to be
paid by Duracell in connection with the Merger. Prior to taking such action, the
Duracell
 
                                       26
<PAGE>   36
 
Board was advised that (i) the investment banking and advisory fees were
disclosed to and discussed with Gillette only after the principal terms of the
Merger, including the Exchange Ratio, were agreed upon by the parties and (ii)
the aggregate investment banking and advisory fees were, on a percentage basis,
within the range of fees paid to advisors to acquired companies in recent large
transactions. The fees were not determined by the Board of Directors to be
disadvantages or risks of the Merger. See "-- Background of the Merger."
 
     THE DURACELL BOARD OF DIRECTORS RECOMMENDS THAT THE HOLDERS OF DURACELL
COMMON STOCK VOTE FOR APPROVAL AND ADOPTION OF THE MERGER AGREEMENT.
 
OPINIONS OF GILLETTE'S FINANCIAL ADVISORS
 
     Each of Merrill Lynch and J.P. Morgan delivered its oral opinion on
September 12, 1996, subsequently confirmed in a written opinion dated the date
of the oral opinion, to the Board of Directors of Gillette that, as of such
date, the consideration to be paid by Gillette in the Merger was fair to
Gillette from a financial point of view. Copies of the opinions of Merrill Lynch
and J.P. Morgan which set forth the assumptions made, matters considered and
limitations on the review undertaken, are attached as Annexes B and C,
respectively, to this Joint Proxy Statement/Prospectus and are incorporated
herein by reference. While the summaries of the opinions of Merrill Lynch and
J.P. Morgan set forth in this Joint Proxy Statement/Prospectus contain all
material provisions of such opinions, such summaries are qualified in their
entirety by reference to the full text of the opinions. The opinions of Merrill
Lynch and J.P. Morgan are addressed to the Gillette Board of Directors, are
directed only to the fairness from a financial point of view of the
consideration to be paid by Gillette pursuant to the Merger and do not
constitute a recommendation to any Gillette stockholder as to how such
stockholder should vote at the Gillette Special Meeting. Gillette's stockholders
are urged to read such opinions in their entirety.
 
Opinion of Merrill Lynch, Pierce, Fenner & Smith Incorporated
 
     On September 12, 1996, Merrill Lynch delivered its oral opinion to the
Gillette Board of Directors, which was subsequently confirmed in a written
opinion dated the date of the oral opinion, to the effect that, as of such date,
and based upon the assumptions made, matters considered and limits of review in
connection with such opinion, the consideration to be paid by Gillette pursuant
to the Merger is fair to Gillette from a financial point of view. References
herein to the "Merrill Lynch Opinion" refer to such written opinion.
 
     In arriving at the Merrill Lynch Opinion, Merrill Lynch: (1) reviewed
Duracell's and Gillette's Annual Reports, Forms 10-K and related information for
the three fiscal years ended June 30, 1995 and December 31, 1995, respectively,
the unaudited financial information for the nine months ended March 31, 1996,
and the six months ended June 30, 1996, respectively, and a draft of Duracell's
financial statements and related Management's Discussion and Analysis for the
fiscal year ended June 30, 1996; (2) reviewed certain information, including
information relating to the future prospects of Duracell and Gillette and
furnished to Merrill Lynch by Duracell's and Gillette's management; (3)
conducted discussions with members of senior management of Duracell and Gillette
concerning the business and prospects of Duracell and Gillette; (4) reviewed the
historical market prices and trading activity for Duracell Common Stock and
Gillette Common Stock and compared them with that of certain publicly traded
companies which Merrill Lynch deemed to be comparable to Duracell and Gillette,
respectively; (5) compared the results of operations of Duracell with that of
certain companies which Merrill Lynch deemed to be comparable to Duracell; (6)
compared the proposed financial terms of the transaction contemplated by the
Merger Agreement with the financial terms of certain other mergers and
acquisitions which Merrill Lynch deemed to be comparable; (7) considered the pro
forma effects of the Merger on Gillette's capitalization ratios, earnings and
cash flow, including pre-tax amounts of synergies expected by Gillette to be
realized following the Merger ranging from approximately $24 million in 1997 to
approximately $116 million in 2001; and (8) reviewed a draft of the Merger
Agreement dated September 12, 1996. While Merrill Lynch considered the amounts
of synergies expected by Gillette to be realized following the Merger, the
conclusion as to fairness included in the Merrill Lynch Opinion does not apply
only in the event such synergies are actually realized.
 
     In preparing the Merrill Lynch Opinion, Merrill Lynch relied upon and
assumed, without independent verification, the accuracy and completeness of all
information that was publicly available or was supplied or otherwise made
available to it by Duracell and Gillette. Merrill Lynch did not conduct any
valuation or appraisal of any assets or liabilities of Duracell or Gillette nor
were any such valuations or appraisals provided
 
                                       27
<PAGE>   37
 
to it. In addition, Merrill Lynch did not make any physical inspections of the
properties or assets of Duracell or Gillette. With respect to information
relating to the future prospects of Duracell and Gillette furnished by Duracell
and Gillette, Merrill Lynch assumed that such information was reasonably
prepared based on assumptions reflecting the best currently available estimates
and judgments by Duracell's and Gillette's management, respectively, as to the
expected future prospects of Duracell and Gillette to which such information
relates. Merrill Lynch also assumed that the Merger will constitute a
reorganization within the meaning of Section 368 of the Internal Revenue Code of
1986, as amended, and will qualify for accounting treatment as a pooling of
interests.
 
     The Merrill Lynch Opinion was necessarily based on economic, market and
other conditions as in effect on, and information made available to it as of,
the date of the Merrill Lynch Opinion. Merrill Lynch expressed no opinion as to
the price at which Gillette Common Stock will trade at any future time.
 
     Merrill Lynch reviewed the historical trading prices and volumes for
Duracell Common Stock. In addition, Merrill Lynch reviewed the consideration to
be paid by Gillette pursuant to the Merger in relation to the September 6, 1996
market price of Duracell Common Stock and Gillette Common Stock. Merrill Lynch
determined that the price of Duracell Common Stock to be paid pursuant to the
Merger Agreement represented a premium of 24.2% based on (i) the September 6,
1996 closing price of $46.75 per share of Duracell Common Stock and (ii) the
September 6, 1996 closing price of $64.25 per share of Gillette Common Stock.
 
     The following is a summary of certain financial and comparative analyses
performed by Merrill Lynch in arriving at its oral opinion delivered to the
Gillette Board of Directors on September 12, 1996.
 
     Comparable Public Companies Analysis.  Using publicly available
information, Merrill Lynch compared certain financial and operating information
and ratios (described below) for Duracell with corresponding financial and
operating information and ratios for a group of publicly traded companies that
Merrill Lynch deemed to be comparable. The companies included in the Duracell
comparable public companies analysis were: The Coca-Cola Company, The Walt
Disney Company, Gillette, Mattel, Inc., Ralston Purina Company, Rubbermaid
Incorporated and Tupperware Corporation (collectively, the "Duracell
Comparables"). These companies were selected, among other reasons, because they
are international market leading, premium-branded, consumer products companies.
Merrill Lynch compared (i) calendarized price/earnings ("P/E") ratios for 1996
and 1997 (based on information from First Call Earnings Estimates ("First
Call")), which ranged from 16.2x to 36.9x for estimated calendar year 1996 (with
a median of 19.1x and a mean of 23.2x), compared to the current trading value of
20.8x for Duracell, and which ranged from 14.2x to 31.3x for estimated calendar
year 1997 (with a median of 16.2x and a mean of 19.8x), compared to the current
trading value of 17.5x for Duracell; (ii) the ratio of market capitalization to
earnings before interest, taxes, depreciation and amortization ("EBITDA") for
the last twelve months ("LTM") which ranged from 8.7x to 25.0x (with a median of
9.9x and a mean of 13.0x), compared to the current trading value of 11.1x for
Duracell; and (iii) 1997 earnings per share ("EPS") multiples (based on
information provided by First Call) expressed as a ratio to the five year
forecast of EPS growth rate (based on information provided by the Institutional
Brokers Estimate System ("IBES")) plus the current dividend yield, which ranged
from .90x to 1.65x (with a median of 1.14x and a mean of 1.19x) compared to the
current trading value of 1.00x for Duracell. In each case, the ratios for
Duracell fell within the range of the equivalent ratios for the Duracell
Comparables. Merrill Lynch performed the analysis described in this paragraph
for the purpose of determining whether the current trading value of Duracell
Common Stock prior to the announcement of the Merger reflected any premium in
anticipation of the Merger or any other extraordinary transaction and therefore
to assess the validity of the comparison of premiums in comparable acquisitions
discussed below.
 
     Discounted Cash Flow Analysis.  Merrill Lynch calculated ranges of equity
values for Duracell based upon the value, discounted to the present, of an
estimated five calendar-year stream of EBITDA through 2001 (both with and
without pre-tax synergies anticipated to be realized as a result of the Merger)
and a projected calendar year 2001 terminal value based on multiples of
estimated net EBITDA ranging from 9.5x to 11.5x. Merrill Lynch prepared the
estimates of Duracell's five calendar-year stream of EBITDA through 2001 based
upon certain publicly available information (including information from First
Call) and discussions with
 
                                       28
<PAGE>   38
 
management of Duracell and Gillette. Merrill Lynch utilized discount rates of
capital ranging from 10.5% to 12.5%. The various ranges for discount rates and
terminal value multiples were chosen to reflect theoretical analyses of cost of
capital and a range of trading values for comparable companies. Based on such
analyses, the implied per share values of Duracell Common Stock ranged from
$50.76 to $66.89 without synergies and from $56.61 to $74.42 with synergies. The
implied value of each share of Duracell Common Stock in the Merger was $58.87 on
September 11, 1996 (the last day before the public announcement of the Merger)
based on the $65.125 closing price per share of Gillette Common Stock on such
date and an exchange ratio of .904 shares of Gillette Common Stock for each
share of Duracell Common Stock.
 
     Comparable Acquisition Analysis.  Merrill Lynch reviewed certain publicly
available information regarding 5 selected battery product transactions between
April 1986 and April 1996 and 6 selected branded consumer product transactions
between November 1991 and January 1995.
 
     The battery product comparables and the dates the transactions were
announced are as follows: Duracell's pending acquisition in South Korea of the
SUNPOWER brand and STC Corporation's sales and distribution operations;
Duracell's acquisition of Eveready South Africa (April 1996); Ralston Purina
Holdings (UK)'s acquisition of Ever Ready Ltd. (April 1992); the acquisition by
KKR affiliates of Duracell (June 1988) and Ralston Purina's acquisition of Union
Carbide's Battery Division (April 1986).
 
     Merrill Lynch compared the "offer value" (defined to be the offer price per
share multiplied by the sum of the number of shares outstanding and the number
of options outstanding) of the acquisition by KKR affiliates of Duracell and
Ralston Purina's acquisition of Union Carbide's Battery Division as a multiple
of then publicly available LTM EPS. The ranges of the offer value as a multiple
of LTM EPS ranged from 28.2x to 27.6x (with a median of 27.9x and a mean of
27.9x) compared to an implied 28.8x to be paid in the Merger. Merrill Lynch also
compared the "transaction value" (defined as the "offer value" plus the
liquidation values of any preferred stock, short term debt, long term debt and
the value of minority interests less cash and equivalents and proceeds from
exercisable options as a multiple of LTM sales (for all five battery products
transactions), of LTM EBITDA (for the acquisition by KKR affiliates of Duracell
and Ralston Purina's acquisition of Union Carbide's Battery Division) and of LTM
earnings before interest and taxes ("EBIT") (for the acquisition by KKR
affiliates of Duracell, Ralston Purina's acquisition of Union Carbide's Battery
Division and Ralston Purina Holdings (UK)'s acquisition of Ever Ready Ltd.). The
ranges of the transaction values as a multiple of LTM sales, LTM EBITDA and LTM
EBIT for such acquisitions were as follows: (i) transaction value to LTM sales
ranged from 1.24x to 2.04x (with a median of 1.59x and a mean of 1.56x) compared
to an implied 3.34x to be paid in the Merger; (ii) transaction value to LTM
EBITDA ranged from 9.5x to 11.1x (with a median of 10.3x and a mean of 10.3x)
compared to an implied 14.7x to be paid in the Merger; and (iii) transaction
value to LTM EBIT ranged from 7.4x to 15.0x (with a median of 12.5x and a mean
of 11.7x) compared to an implied 18.0x to be paid in the Merger.
 
     The branded consumer product comparables and the dates the transactions
were announced are as follows: Colgate-Palmolive Co.'s acquisition of the
Kolynos business of American Home Products (January 1995); Johnson & Johnson's
acquisition of Neutrogena Corp. (August 1994); Reckitt & Coleman PLC's
acquisition of Lehn & Fink (September 1994); Mattel Inc.'s acquisition of
Fisher-Price (August 1993); S.C. Johnson & Sons, Inc.'s acquisition of Drackett
Co. (October 1992) and Newell's acquisition of Sanford Corp. (November 1991).
 
     Merrill Lynch compared the offer value of the acquisitions of Neutrogena,
Fisher-Price and Sanford Corp. as a multiple of then publicly available LTM EPS.
The ranges of the offer value as a multiple of LTM EPS ranged from 25.2x to
37.5x (with a median of 30.7x and a mean of 31.1x) compared to an implied 28.8x
paid in the Merger. Merrill Lynch also compared the transaction value as a
multiple of LTM sales (for all six consumer product transactions), of LTM EBITDA
(for the acquisitions of Neutrogena, Fisher-Price and Sanford Corp.) and of LTM
EBIT (for the acquisitions of Neutrogena, Lehn & Fink, Fisher-Price and Sanford
Corp.). The ranges of the transaction value as a multiple of LTM sales, LTM
EBITDA and LTM EBIT for such acquisitions were as follows: (i) transaction value
to LTM sales ranged from 1.72x to 4.21x (with a median of 2.56x and a mean of
2.76x) compared to an implied 3.34x to be paid in the Merger; (ii) transaction
value to LTM EBITDA ranged from 12.6x to 20.2x (with a median of 14.4x and a
mean of
 
                                       29
<PAGE>   39
 
15.7x) compared to an implied 14.7x to be paid in the Merger; and (iii)
transaction value to LTM EBIT ranged from 13.0x to 23.3x (with a median of 16.8x
and a mean of 17.5x) compared to an implied 18.0x to be paid in the Merger.
 
     Merrill Lynch also compared the premium to be paid in the Merger to the
premium to the closing market price one month prior to announcement of the
acquisitions of Neutrogena, Fisher-Price and Sanford Corp. which ranged from
22.6% to 53.0% (with a median of 43.6% and a mean of 39.7%) as compared to 24.2%
for the Merger based on the closing sales prices of $64.25 and $46.75 per share
for the Gillette Common Stock and Duracell Common Stock, respectively, on
September 6, 1996.
 
     Merrill Lynch based its LTM information on the financial data contained in
Duracell's draft annual report for the fiscal year ended June 30, 1996 which was
made available to Merrill Lynch. The offer value and transaction were calculated
using the September 6, 1996 closing sales price of Gillette Common Stock and the
Exchange Ratio.
 
     Relative Contribution Analysis.  Merrill Lynch compared the relative
ownership of the holders of Gillette Common Stock and the holders of Duracell
Common Stock with respect to the combined company of approximately 80.1% and
19.9%, respectively, to the relative contributions of each of Gillette and
Duracell to the combined company's revenues, EBITDA, EBIT and net income based
on publicly available information and discussions with management of Duracell
and Gillette, before synergies and transaction adjustments. This analysis
indicated that for 1996, Duracell would contribute 25.2% of the revenues of the
combined entity, 24% of the EBITDA of the combined entity, 23.6% of the EBIT of
the combined entity, and 21.8% of the net income of the combined entity.
 
     Implied Exchange Ratio.  Merrill Lynch reviewed the implied exchange ratio
derived from discounted cash flow ("DCF") analysis of Duracell described above
and a DCF analysis of Gillette prepared by Merrill Lynch on the basis of
publicly available information and discussions with management of Gillette. By
comparing the highest implied values of Duracell to the lowest implied values of
Gillette, and vice-versa, the indicated results were as follows: (i) Duracell
stand-alone DCF to Gillette stand-alone DCF yielded an implied exchange ratio of
0.83 to 0.92; and (ii) Duracell stand-alone DCF to Gillette stand-alone DCF with
synergies yielded an implied exchange ratio of 0.92 to 1.02.
 
     Pro Forma EPS Analyses.  Merrill Lynch analyzed certain pro forma effects
resulting from the Merger, including the potential impact of the Merger on
projected EPS for the combined company assuming lower and higher compound annual
growth rates and, in each such case, with and without synergies. In all
scenarios, the Merger would be accretive to the holders of Gillette Common Stock
in the years 1997, 1998 and 1999.
 
     The summary set forth above, while containing all material elements of the
analyses performed by Merrill Lynch, does not purport to be a complete
description of such analyses. Arriving at a fairness opinion is a complex
process not necessarily susceptible to partial or summary description. Merrill
Lynch believes that its analysis must be considered as a whole and that
selecting portions of its analyses and of the factors considered by it, without
considering all such factors and analyses, could create a misleading view of the
process underlying its analyses set forth in the Merrill Lynch Opinion. The
matters considered by Merrill Lynch in its analyses are based on numerous
macroeconomic, operating and financial assumptions with respect to industry
performance, general business and economic conditions and other matters, many of
which are beyond Duracell's or Gillette's control and involve the application of
complex methodologies and educated judgment. Any estimates incorporated in the
analyses performed by Merrill Lynch are not necessarily indicative of actual
past or future results or values, which may be significantly more or less
favorable than such estimates. Estimated values do not purport to be appraisals
and do not necessarily reflect the prices at which businesses or companies may
be sold in the future, and such estimates are inherently subject to uncertainty.
No public company utilized as a comparison is identical to Duracell or Gillette,
and none of the acquisition comparables or other business combinations utilized
as a comparison is identical to the proposed Merger. Accordingly, an analysis of
publicly traded comparable companies and comparable business combinations is not
mathematical; rather it involves complex considerations and judgments concerning
differences in financial and operating characteristics of the comparable
companies and other factors that could affect the public trading value of the
comparable companies or company to which they are being compared.

     The Gillette Board of Directors selected Merrill Lynch to act as one of its
financial advisors on the basis of Merrill Lynch's reputation as an
internationally recognized investment banking firm with substantial expertise in
transactions similar to the Merger and because it is familiar with Gillette and
its business. As part of its investment banking business, Merrill Lynch is
continually engaged in the valuation of businesses and their securities in
connection with mergers and acquisitions.
 
     Merrill Lynch Fees.  With respect to Merrill Lynch's services as a
financial advisor in connection with the Merger, pursuant to a letter agreement
dated January 12, 1996, Gillette has agreed to pay Merrill Lynch $8,000,000 upon
consummation of the Merger. In addition, Gillette also has agreed to reimburse
Merrill Lynch for its reasonable out-of-pocket expenses (including reasonable
fees and expenses of its legal counsel) and to indemnify Merrill Lynch and
certain related persons against certain liabilities, including liabilities under
the federal securities laws, arising out of its engagement.
 
     Merrill Lynch has, in the past, provided financial advisory and financing
services to Gillette and Duracell and has received fees for rendering such
services. In addition, in the ordinary course of their businesses, Merrill Lynch
and its affiliates may actively trade the debt and equity securities of Gillette
and Duracell for their own accounts or for the accounts of customers and,
accordingly, they may at any time hold long or short positions in such
securities.
 
Opinion of J.P. Morgan Securities Inc.
 
     Pursuant to an engagement letter dated January 12, 1996, Gillette retained
J.P. Morgan as a financial advisor in connection with the proposed Merger.
 
     At the meeting of the Board of Directors of Gillette on September 12, 1996,
J.P. Morgan rendered its oral opinion to the Board of Directors of Gillette
which was subsequently confirmed in a written opinion dated the date of the oral
opinion that, as of such date, the consideration to be paid by Gillette in the
proposed Merger was fair from a financial point of view to Gillette.
 
     In arriving at its opinion, J.P. Morgan reviewed a draft of the Merger
Agreement, Gillette's and Duracell's Annual Reports, Forms 10-K and related
information for the three fiscal years ended December 31, 1995, and June 30,
1995, respectively, the unaudited financial information for the six months ended
June 30, 1996, and the nine months ended March 31, 1996, respectively, and a
draft of Duracell's financial statements and related Management's Discussion and
Analysis for the fiscal year ended June 30, 1996; current and historical market
prices of Gillette Common Stock and Duracell Common Stock; certain publicly
available information concerning the business of Gillette and Duracell and of
certain other companies engaged in businesses comparable to those of Duracell,
and the reported market prices for certain other companies securities deemed
comparable; publicly available terms of certain transactions involving companies
comparable to Duracell and the consideration paid for such companies; and the
terms of other business combinations deemed relevant by J.P. Morgan. J.P. Morgan
also held discussions with certain members of the management of Gillette and
Duracell with respect to certain aspects of the Merger, and the past and current
business operations of Gillette and Duracell, the financial condition and future
prospects and operations of Gillette and Duracell (including the pre-tax amounts
of synergies expected by Gillette to be realized following the Merger ranging
from approximately $24 million in 1997 to approximately $116 million in 2001),
and certain other matters believed necessary or appropriate to J.P. Morgan's
inquiry. With respect to information regarding the future prospects of Gillette
and Duracell furnished by Gillette and Duracell, J.P. Morgan assumed that such
information was reasonably prepared based on assumptions reflecting the best
currently available estimates and judgments by Gillette's and Duracell's
management, respectively, as to the expected future prospects of Gillette and
Duracell to which such information relates. While J.P. Morgan considered the
amounts of synergies expected by Gillette to be realized following the Merger,
the conclusion as to fairness included in the J.P. Morgan opinion does not apply
only in the event such synergies are actually realized.
 
     J.P. Morgan relied upon and assumed, without independent verification, the
accuracy and completeness of all information that was publicly available or that
was furnished to it by Gillette and Duracell or otherwise reviewed by J.P.
Morgan, and J.P. Morgan has not assumed any responsibility or liability
therefor. J.P. Morgan did not conduct any valuation or appraisal of any assets
or liabilities, nor were any valuations or
 
                                       31
<PAGE>   41
 
appraisals provided to J.P. Morgan. J.P. Morgan did not make any physical
inspection of the properties or assets of Gillette or Duracell. J.P. Morgan also
assumed that the Merger will constitute a reorganization within the meaning of
Section 368 of the Internal Revenue Code of 1986, as amended, and will qualify
for accounting treatment as a pooling of interests.
 
     J.P. Morgan's opinion is based on economic, market and other conditions as
in effect on, and the information made available to J.P. Morgan as of, the date
of such opinion. Subsequent developments may affect the written opinion dated
September 12, 1996, and J.P. Morgan does not have any obligation to update,
revise, or reaffirm such opinion. J.P. Morgan expressed no opinion as to the
price at which the Gillette Common Stock will trade at any future time.
 
     In accordance with customary investment banking practice, J.P. Morgan
employed generally accepted valuation methods in reaching its opinion. The
following is a summary of the material financial analyses utilized by J.P.
Morgan in connection with providing its opinion.
 
     Public Trading Multiples Analysis.  Using publicly available information,
J.P. Morgan compared selected financial data of Duracell with similar data for
selected publicly traded companies engaged in businesses which J.P. Morgan
judged to be comparable to Duracell. The companies selected by J.P. Morgan were
Clorox Company, The Coca-Cola Company, Gillette, Mattel Incorporated, McDonald's
Corporation, Ralston-Purina Group, Rubbermaid Incorporated and Tupperware
Corporation. These companies were selected, among other reasons, because they
are international market leading, premium-branded, consumer products companies.
For each selected company, market valuation multiples based on publicly
available financial statements through the twelve months ended June 30, 1996 and
financial projections based on First Call (a brokers' earnings estimate and news
survey which is updated daily) median earnings per share forecasts were
calculated. J.P. Morgan examined the median value for each multiple,
specifically: firm value to sales (2.33x); firm value to EBIT (13.5x); firm
value to EBITDA (10.7x); equity value to net income (21.3x); firm value to
projected 1996 EBIT (12.6x); firm value to projected 1996 EBITDA (10.0x); equity
value to projected 1996 net income (20.4x) and equity value to projected 1997
net income (18.2x). These multiples were then applied to Duracell's trailing
twelve months sales, EBIT, EBITDA, net income and projected 1996 EBIT, 1996
EBITDA, 1996 net income and 1997 net income, yielding implied trading values for
Duracell Common Stock of approximately $44.00 to $54.00 per share, not including
synergies. Including synergies, the multiples yielded implied trading values for
Duracell Common Stock of approximately $54.00 to $64.50 per share. The implied
value of each share of Duracell Common Stock in the Merger was $58.87 on
September 11, 1996 (the last day before the public announcement of the Merger)
based on the $65.125 closing price per share of Gillette Common Stock on such
date and an exchange ratio of .904 shares of Gillette Common Stock for each
share of Duracell Common Stock.
 
     Selected Transaction Analysis.  Using publicly available information, J.P.
Morgan examined selected transactions in the battery and premium branded
consumer products industries with respect to firm value, firm value as a
multiple of trailing twelve months EBIT and equity value as a multiple of
trailing twelve months net income. Specifically, J.P. Morgan reviewed the
following transactions in the battery industry: Thomas H. Lee Company's
acquisition of Rayovac; Duracell's pending acquisition in South Korea of the
SUNPOWER brand and STC Corporation's sales and distribution operations;
Duracell's acquisition of Eveready South Africa; Ralston Purina Holdings (UK)'s
acquisition of Ever Ready Ltd.; SADT's acquisition of Investment AV Cardo;
Eveready Batteries acquisition of Cofinea; the acquisition by KKR affiliates of
Duracell; Chloride Group acquisition of Powerline International; and Ralston
Purina's acquisition of Union Carbide's Battery Division. J.P. Morgan reviewed
the following transactions in the premium branded consumer products industry:
Cadbury Schweppes' acquisition of Dr. Pepper/Seven Up; Sandoz's acquisition of
Gerber Products; the acquisition by KKR affiliates of Borden; Quaker Oats'
acquisition of Snapple Beverage; Pillsbury's acquisition of Pet; Luxottica's
acquisition of U.S. Shoe; Interbrew's acquisition of John Labatt; Johnson &
Johnson's acquisition of Neutrogena; and Mattel's acquisition of Fisher Price.
J.P. Morgan applied the median of the multiples derived from such analysis to
Duracell's trailing twelve months EBIT (17.2x) and trailing twelve months net
income (27.9x), and arrived at an estimated range of equity values for Duracell
Common Stock of between $57.50 and $69.50 per share. The implied value of each
share of Duracell Common Stock in the Merger was $58.87 on September 11, 1996
(the last day before the public announcement of the Merger)
 
                                       32
<PAGE>   42
 
based on the $65.125 closing price per share of Gillette Common Stock on such
date and an exchange ratio of .904 shares of Gillette Common Stock for each
share of Duracell Common Stock.
 
     Discounted Cash Flow Analysis.  J.P. Morgan conducted a discounted cash
flow analysis for the purpose of determining the fully diluted equity value per
share for Duracell Common Stock. J.P. Morgan estimated the unlevered free cash
flows of Duracell for the calendar years 1997 through 2001 based upon publicly
available information and discussions with management of Duracell and Gillette.
J.P. Morgan also analyzed a scenario designed to reflect more moderate growth in
revenues and lower operating margins for Duracell during the 5-year period. J.P.
Morgan also calculated a range of terminal asset values of Duracell at the end
of the 5-year period ending 2001 by applying a range of EBITDA multiples between
9.0 and 10.0 times Duracell's estimated 2001 EBITDA. The unlevered free cash
flows and the range of terminal asset values were then discounted to present
values using a range of discount rates from 9.50% to 10.50%, which were chosen
by J.P. Morgan based upon an analysis of the weighted average cost of capital of
Duracell. The present value of the unlevered free cash flows and the range of
terminal asset values were then adjusted for Duracell's estimated 1996 calendar
year-end excess cash, option exercise proceeds and total debt. Based on the
methodology described above, the discounted cash flow analysis indicated a range
of equity values of between $52.00 and $79.00 per share of Duracell Common Stock
on a stand-alone basis without synergies. Including synergies, the discounted
cash flow analysis indicated a range of equity values of between $62.50 and
$89.50. The implied value of each share of Duracell Common Stock in the Merger
was $58.87 on September 11, 1996 (the last day before the public announcement of
the Merger) based on the closing price of $65.125 per share of Gillette Common
Stock on such date and an exchange ratio of .904 shares of Gillette Common Stock
for each share of Duracell Common Stock.
 
     Pro forma Merger Analysis.  J.P. Morgan analyzed certain pro forma effects
resulting from the Merger based on (i) projected 1997 through 2000 earnings for
Gillette and Duracell based on publicly available information (including
projected earnings estimates of equity analysts as compiled by First Call) and
discussions with management of Gillette and Duracell and (ii) projected
synergies estimated by Gillette management. This analysis indicated that the
transaction would be accretive to EPS in 1997.
 
     Relative Value Analysis Based on Discounted Cash Flows.  Based on the
projections described above, J.P. Morgan calculated the exchange ratio implied
by the relative values of the discounted cash flows generated by Gillette and
Duracell on a stand-alone basis. Assuming no synergies, the analysis implied a
range of exchange ratios of 0.83 to 0.95. Assuming synergies, the analysis
implied a range of exchange ratios of 0.99 to 1.12.
 
     Relative Value Analysis Based on Selected Trading Multiples.  Based on the
selected trading multiples analysis described above, J.P. Morgan calculated the
implied exchange ratio. Assuming no synergies, the analysis implied a range of
exchange ratios of 0.68 to 0.84. Assuming synergies, the analysis implied a
range of exchange ratios of 0.84 to 1.00.
 
     Contribution Analysis.  J.P. Morgan compared the relative ownership of the
holders of Gillette Common Stock and the holders of Duracell Common Stock with
respect to the combined company of approximately 80.1% and 19.9%, respectively,
to the relative contribution to the combined company of the sales and operating
income of each of Gillette and Duracell for the twelve months ended December 31,
1995. This analysis showed that Gillette and Duracell would contribute
approximately 75.7% and 24.3% of sales, respectively, and 76.2% and 23.8% of
operating income, respectively.
 
     The description of J.P. Morgan's analyses set forth above summarizes the
material aspects of the analyses performed but does not purport to be a complete
description of the analyses or data presented by J.P. Morgan. The preparation of
a fairness opinion is a complex process and is not necessarily susceptible to
partial analysis or summary description. J.P. Morgan believes that the summary
set forth above and its analyses must be considered as a whole and that
selecting portions thereof, without considering all of its analyses, could
create an incomplete view of the processes underlying its analyses and opinion.
J.P. Morgan based its analyses on assumptions that it deemed reasonable,
including assumptions concerning general business and economic conditions and
industry-specific factors. The other principal assumptions upon which J.P.
Morgan based its analyses are set forth above under the description of each such
analysis. J.P. Morgan's analyses are not
 
                                       33
<PAGE>   43
 
necessarily indicative of actual values or actual future results that might be
achieved, which values may be higher or lower than those indicated. Moreover,
J.P. Morgan's analyses are not and do not purport to be appraisals or otherwise
reflective of the prices at which businesses actually could be bought or sold.
 
     As a part of its investment banking business, J.P. Morgan and its
affiliates are continually engaged in the valuation of businesses and their
securities in connection with mergers and acquisitions, investments for passive
and control purposes, negotiated underwritings, secondary distributions of
listed and unlisted securities, private placements, and valuations for estate,
corporate and other purposes. J.P. Morgan was selected to advise Gillette with
respect to the Merger on the basis of such experience and its familiarity with
Gillette.
 
     For services rendered in connection with the Merger, Gillette has agreed to
pay J.P. Morgan a fee of $8,000,000 upon consummation of the Merger. In
addition, Gillette has agreed to reimburse J.P. Morgan for its reasonable
out-of-pocket expenses incurred in connection with its services, including the
reasonable fees and disbursements of counsel, and to indemnify J.P. Morgan
against certain liabilities, including liabilities arising under the federal
securities laws.
 
     J.P. Morgan and its affiliates maintain banking and other business
relationships with Gillette, for which they receive customary fees. Its
affiliate, Morgan Guaranty Trust Company of New York, has been the agent bank on
Gillette's revolving credit facilities since 1986 and has received fees for such
services. In addition, in the ordinary course of their businesses, J.P. Morgan
and its affiliates may actively trade the debt and equity securities of Gillette
or Duracell for their own accounts or for the accounts of customers and,
accordingly, they may at any time hold long or short positions in such
securities.
 
OPINION OF DURACELL'S FINANCIAL ADVISOR
 
     Morgan Stanley was retained by Duracell to provide an opinion in connection
with the Merger and related matters based upon Morgan Stanley's experience and
expertise. At the September 12, 1996 meeting of the Board of Directors of
Duracell, Morgan Stanley rendered to the Board of Directors of Duracell an oral
opinion, confirmed in writing as of such date, to the effect that, as of such
date and based on and subject to certain matters stated therein, the Exchange
Ratio pursuant to the Merger Agreement was fair from a financial point of view
to the holders of shares of Duracell Common Stock.
 
     The full text of the Morgan Stanley opinion dated September 12, 1996, which
sets forth the assumptions made, matters considered and limitations on the
review undertaken, is attached as Annex D to this Joint Proxy
Statement/Prospectus and is incorporated herein by reference. Holders of
Duracell Common Stock should read the Morgan Stanley opinion carefully in its
entirety. The Morgan Stanley opinion is directed to the Board of Directors of
Duracell and the fairness of the Exchange Ratio from a financial point of view
to the holders of shares of Duracell Common Stock, and it does not address any
other aspect of the Merger nor does it constitute a recommendation to any holder
of Duracell Common Stock as to how to vote at the Duracell Special Meeting. The
summary of the Morgan Stanley opinion set forth in this Joint Proxy
Statement/Prospectus, while containing all material provisions of such opinion,
is qualified in its entirety by reference to the full text of such opinion.
 
     In arriving at its opinion, Morgan Stanley (i) analyzed certain publicly
available financial statements and other information of Duracell; (ii) analyzed
certain publicly available financial statements and other information of
Gillette; (iii) analyzed certain internal financial statements and other
financial and operating data concerning Duracell prepared by the management of
Duracell; (iv) analyzed certain financial projections prepared by management of
Duracell; (v) discussed the past and current operations and financial condition
and the prospects of Duracell with senior executives of Duracell; (vi) discussed
the past and current operations and financial condition and the prospects of
Gillette with senior executives of Gillette (which discussions Morgan Stanley
viewed as consistent with publicly available analysts' reports regarding
Gillette) and analyzed the proforma impact of the Merger on Gillette's earnings
per share; (vii) reviewed the reported prices and trading activity for Gillette
Common Stock; (viii) reviewed the reported prices and trading activity for the
Duracell Common Stock; (ix) compared the financial performance of Duracell and
the prices and trading activity of Duracell Common Stock with that of certain
other comparable publicly-traded companies
 
                                       34
<PAGE>   44
 
and their securities; (x) reviewed the financial terms, to the extent publicly
available, of certain comparable acquisition transactions; (xi) discussed with
senior executives of Duracell and Gillette their views of the strategic
rationale for the Merger and the economic benefits of the Merger to Gillette;
(xii) participated in discussions and negotiations among representatives of
Duracell and Gillette and their financial and legal advisors; and (xiii)
reviewed the Merger Agreement. Morgan Stanley did not make any independent
valuation or appraisal of the assets or liabilities of Duracell, nor was Morgan
Stanley furnished with any such appraisals. While Morgan Stanley considered the
synergies expected to be realized by Gillette following the Merger, Morgan
Stanley did not separately consider the effects of synergies on the fairness of
the Exchange Ratio.
 
     In rendering its opinion, Morgan Stanley assumed and relied upon, without
independent verification, the accuracy and completeness of the information
reviewed by Morgan Stanley for purposes of its opinion. With respect to
financial projections, Morgan Stanley assumed that they had been reasonably
prepared on bases reflecting the best currently available estimates and
judgments of the future financial performance of Duracell. Morgan Stanley relied
upon, with the consent of Duracell, the assumptions of the management of
Duracell and Gillette regarding cost savings and other synergies that will
result from the Merger. Morgan Stanley assumed that the Merger will qualify as a
"pooling of interests" business combination for accounting and financial
reporting purposes and will qualify as a tax-free "reorganization" within the
meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended.
Morgan Stanley also assumed that the Merger will be consummated in accordance
with the terms set forth in the Merger Agreement. The Morgan Stanley opinion is
necessarily based on economic, market and other conditions as in effect on, and
the information made available to Morgan Stanley as of, the date thereof.
 
     In arriving at its opinion, Morgan Stanley was not authorized to solicit,
and did not solicit, interest from any party with respect to the acquisition of
Duracell.
 
     The following is a brief summary of certain analyses performed by Morgan
Stanley and reviewed with the Board of Directors of Duracell in connection with
the preparation of the Morgan Stanley opinion dated September 12, 1996 and with
its oral presentation to the Board of Directors of Duracell on September 12,
1996.
 
     Public Market Overview.  Morgan Stanley reviewed certain trading
information for each of Duracell and Gillette, including market value, market
capitalization and institutional ownership. Morgan Stanley also reviewed
historical and forward trading multiples for each company.
 
     Historical Stock Performance.  Morgan Stanley compared the trading price of
the shares of Duracell Common Stock and Gillette Common Stock. This stock
performance review indicated that for Duracell's and Gillette's LTM ended
September 6, 1996, the high and low closing prices for shares of Duracell Common
Stock and Gillette Common Stock were $54.88 and $40.38 and $66.38 and $41.25,
respectively. Morgan Stanley observed that implied price per share of Duracell
Common Stock of $58.76 (assuming the Exchange Ratio of 0.904 shares of Gillette
Common Stock for each share of Duracell Common Stock and a Gillette Common Stock
price of $65.00) represented a premium to the LTM low and high price of Duracell
Common Stock of 45.5% and 7.1%, respectively.
 
     Comparable Company Trading Analysis.  Morgan Stanley performed a comparable
public company trading analysis pursuant to which it compared certain publicly
available financial and operating data, projections of future financial
performance and market statistics (based upon closing stock prices on September
6, 1996) of Avon Products Incorporated, Colgate-Palmolive Company, Clorox
Company, Newell Company, The Procter & Gamble Company, Ralston-Purina Company
and Rubbermaid Incorporated (collectively, the "Selected Comparable Companies").
These companies were selected because of their comparability to Duracell, each
being a leading publicly-traded manufacturer of consumer non-durable products.
Morgan Stanley compared (i) the closing stock price of the Selected Comparable
Companies as a multiple of estimated 1996 and 1997 EPS based upon information
from Institutional Brokers Estimate System ("IBES") and (ii) the aggregate value
(consisting of market capitalization and total debt) as a multiple of each LTM
EBITDA and EBIT.
 
                                       35
<PAGE>   45
 
     For the Selected Comparable Companies, such analysis indicated: (i) median
price to estimated 1996 EPS multiple of 19.7x, (ii) median price to estimated
1997 EPS multiple of 17.5x, (iii) median aggregate value to LTM EBITDA multiple
of 10.6x and (iv) median aggregate value to LTM EBIT multiple of 13.5x.
 
     Morgan Stanley calculated the fully-diluted aggregate value of each of
Duracell and Gillette (assuming an Exchange Ratio of 0.904 shares of Gillette
Common Stock for each share of Duracell Common Stock and a Gillette stock price
of $65.00) of $7,733 million and $28,956 million, respectively, as a multiple of
each of their respective LTM EBITDA and EBIT. The multiples yielded by such
calculation were (i) with respect to EBITDA, 14.3x and 17.4x, respectively, and
(ii) with respect to EBIT, 17.4x and 20.6x, respectively.
 
     Morgan Stanley also calculated the ratio of price per share to IBES median
estimated 1996 and 1997 earnings per share for each of Duracell and Gillette.
Assuming an exchange ratio of 0.904 shares of Gillette Common Stock for each
share of Duracell Common Stock and a Gillette stock price of $65.00 per share,
Duracell's ratio of price to IBES median estimated earnings for 1996 and 1997
was 26.1 and 22.6, respectively. Assuming a Gillette stock price of $65.00 per
share, Gillette's price to IBES median estimated earnings for 1996 and 1997 was
calculated to be 30.2 and 26.0, respectively.
 
     No company utilized as a comparison in the comparable companies analysis is
identical to Duracell. In evaluating the comparable companies, Morgan Stanley
made judgments and assumptions with regard to industry performance, general
business, economic, market and financial conditions and other matters, many of
which are beyond the control of Duracell, such as the impact of competition on
Duracell and the industry generally, industry growth and the absence of any
adverse material change in the financial condition and prospects of Duracell or
the industry or in the financial markets in general.
 
     Comparable Precedent Transaction Analysis.  Morgan Stanley reviewed certain
publicly available information regarding 16 transactions from 1986 to 1996
involving the acquisition of manufacturers of non-durable consumer products
companies with sales, distribution and marketing characteristics determined to
be comparable to Duracell and for each transaction calculated where available
(i) the equity value as a multiple of each of LTM earnings (9 transactions
available) and (ii) the asset value as a multiple of sales (15 transactions
available), EBITDA (9 transactions available) and EBIT (14 transactions
available). Such analysis indicated that equity value as a multiple of earnings
ranged from 19.8x to 36.6x, with a mean of 27.7x and a median of 25.7x. Such
analysis also indicated that asset value as a multiple of sales, EBITDA and
EBIT, respectively, (i) ranged from 3.6x to 0.7x, with a mean of 2.1x and a
median of 2.0x, (ii) ranged from 10.0x to 19.9x, with a mean of 13.8x and a
median of 13.4x and (iii) ranged from 12.0x to 36.6x, with a mean of 20.0x and a
median of 18.4x. With respect to Duracell, the equity value as a multiple of LTM
earnings and the asset value as a multiple of sales, EBITDA and EBIT were 28.0x,
3.4x, 17.4x and 14.3x, respectively.
 
     For such transactions, Morgan Stanley also calculated where available the
equity value as a multiple of LTM after-tax cash flow ("OCF") (4 transactions
available) and book value (10 transactions available). Such analysis indicated
that equity value, as a multiple of OCF and book value, respectively, ranged
from 13.0x to 21.6x with a mean of 18.5x and a median of 19.7x and ranged from
2.9x to 35.7x, with a mean of 10.6x and a median of 5.2x. Multiples of OCF and
book value were not calculated for the Duracell transaction as they were not
material to the analysis.
 
     Morgan Stanley also analyzed ten share-for-share transactions each with an
aggregate value in excess of $4 billion announced in 1995 to 1996. Such analysis
indicated that the premium to unaffected price ranged from 8.7% to 42.0%, with a
mean of 27.9% and a median of 29.7%. Such analysis also indicated that, assuming
an exchange ratio of 0.904 shares of Gillette Common Stock for each share of
Duracell Common Stock and a Gillette stock price of $65.00 per share the premium
to unaffected price was 30.9%.
 
     No transaction utilized in the comparable transaction analysis is identical
to the Merger. In evaluating the precedent transactions, Morgan Stanley made
judgments and assumptions with regard to industry performance, general business,
economic, market and financial conditions and other matters, many of which are
beyond the control of Duracell, such as the impact of competition on the
business of Duracell and the industry generally, industry growth and the absence
of any adverse material change in the financial condition and prospects of
Duracell or the industry or in the financial markets in general. Mathematical
analysis (such as determining the average or median) is not in itself a
meaningful method of using comparable transaction data.

<PAGE>   46
 
     Discounted Cash Flow Analysis.  Morgan Stanley performed a discounted cash
flow analysis to calculate a present value of the stand-alone unlevered free
cash flows that Gillette and Duracell are expected to generate if Gillette and
Duracell perform in accordance with certain assumed scenarios. With respect to
Duracell, Morgan Stanley analyzed three scenarios: (i) the "Duracell High Case"
which was based on publicly available information, discussions with Duracell
management and certain financial forecasts prepared by Duracell management; (ii)
the "Adjusted Duracell Case" which adjusted downward the aforementioned Duracell
High Case based on several contingencies specified by Duracell management and
(iii) the "15% Growth Case" which was based on a set of financial forecasts
which utilized IBES earnings estimates and the 15% median long-term earnings
growth rate projected by IBES. With respect to Gillette, Morgan Stanley analyzed
two scenarios: (i) the "Gillette High Case" and (ii) the "Gillette Low Case,"
both of which were based on publicly available information and discussions with
Gillette management. For each scenario, Morgan Stanley discounted the estimated
unleveraged free cash flows using a discount rate of 12.5%. Morgan Stanley added
to the present values of the cash flows the terminal values of Gillette and
Duracell, respectively, in the year 2006, and discounted the terminal value
using the 12.5% discount rate. The terminal value was calculated using the
perpetuity method, assuming a range of perpetual growth rates between 5% and 7%
for Duracell and 6% and 8% for Gillette. Based on this analysis, Morgan Stanley
calculated a per share equity value of Duracell ranging from $57.46 to $71.91
based on the Duracell High Case, $51.00 to $64.08 using the Adjusted Duracell
Case and $42.78 to $53.59 using the 15% Growth Case. The per share equity values
calculated for Gillette ranged from $63.87 to $84.00 using the Gillette High
Case and $56.85 to $74.55 using the Gillette Low Case. The per share equity
value ranges for Duracell and Gillette implied by the discounted cash flow
methodology were discussed with the Duracell board as one means for considering
the value of the companies' unleveraged free operating cash flows.
 
     Historical Exchange Ratio Analysis.  Morgan Stanley analyzed the historical
exchange ratio between Duracell Common Stock and Gillette Common Stock over
several time periods. For each time period selected, the high, average and low
exchange ratios were calculated. The time periods as of September 6, 1996
selected for the analysis were as follows: last two years, last twelve months,
last six months, last 90 days, last 60 days, last 30 days, last 10 days and
closing price on September 6, 1996 (for which only the average exchange ratio
was calculated). The average exchange ratio for each aforementioned time period
was 0.994, 0.884, 0.790, 0.716, 0.708, 0.711, 0.707 and 0.728, respectively.
 
     Analysis of Exchange Ratio Implied by Discounted Cash Flow
Analysis.  Morgan Stanley calculated the range of exchange ratios implied by
dividing the low end of the value range per Duracell share suggested by the
various Duracell discounted cash flow scenarios by the low end of the value
range per Gillette share suggested by various Gillette discounted cash flow
scenarios. For the purposes of this analysis, the Duracell scenarios and
Gillette scenarios were as follows: (i) 15% Growth Case and Gillette Low Case;
(ii) Adjusted Duracell Case and Gillette Low Case; (iii) Adjusted Duracell Case
and Gillette High Case; and (iv) Duracell High Case and Gillette High Case. The
ranges of implied exchange ratios derived from comparing these scenarios were
(i) 0.719 to 0.752; (ii) 0.859 to 0.897; (iii) 0.763 to 0.799; and (iv) 0.856 to
0.900, respectively.
 
     The preparation of a fairness opinion is a complex process and is not
necessarily susceptible to a partial analysis or summary description. In
arriving at its opinion, Morgan Stanley considered the results of all of its
analyses as a whole and did not attribute any particular weight to any
particular analysis or factor considered by it. Furthermore, selecting any
portion of Morgan Stanley's analyses, without considering all analyses, would
create an incomplete view of the process underlying the Morgan Stanley opinion.
In addition, Morgan Stanley may have deemed various assumptions more or less
probable than other assumptions, so that the ranges of valuations resulting for
any particular analysis described above should not be taken to be Morgan
Stanley's view of the actual value of Duracell or Gillette.
 
     In performing its analyses, Morgan Stanley made numerous assumptions with
respect to industry performance, general business and economic conditions and
other matters, many of which are beyond the control of Duracell or Gillette. The
analyses performed by Morgan Stanley are not necessarily indicative of actual
values, which may be significantly more or less favorable than suggested by such
analyses. Such analyses were prepared solely as a part of Morgan Stanley's
analysis of the fairness of the Exchange Ratio from a financial point of view to
the holders of shares of Duracell Common Stock and were provided to the
 
                                       37
<PAGE>   47
 
Board of Directors of Duracell in connection with the delivery of the Morgan
Stanley opinion. The analyses do not purport to be appraisals or to reflect the
prices at which Duracell or Gillette might actually be sold. In addition, as
described above, the Morgan Stanley opinion, including Morgan Stanley's
presentation to the Board of Directors of Duracell, was one of many factors
taken into consideration by the Board of Directors of Duracell in making its
determination to approve the Merger.
 
     The Board of Directors of Duracell retained Morgan Stanley based upon
Morgan Stanley's experience and expertise. Morgan Stanley is an internationally
recognized investment banking and financial advisory firm. Morgan Stanley, as
part of its investment banking business, is continuously engaged in the
valuation of businesses and securities in connection with mergers and
acquisitions, negotiated underwritings, competitive biddings, secondary
distributions of listed and unlisted securities, private placements and
valuations for corporate and other purposes. Morgan Stanley is a full-service
securities firm engaged in securities trading and brokerage activities, as well
as providing investment banking and financial advisory services. In the ordinary
course of its trading and brokerage activities, Morgan Stanley or its affiliates

transactions, for its own account or the accounts of customers, in securities of
Duracell or Gillette. In the past, Morgan Stanley and its affiliates have
provided financial advisory and financing services to Duracell and its
affiliates and Gillette and have received customary fees for the rendering of
these services.
 
     Pursuant to a letter agreement dated September 12, 1996, Duracell has
agreed to pay Morgan Stanley a transaction fee equal to $10 million, payable
upon consummation of the Merger. In addition to the foregoing compensation,
Duracell has agreed to reimburse Morgan Stanley for its expenses, including
reasonable fees and expenses of its counsel, and to indemnify Morgan Stanley for
liabilities and expenses arising out of the engagement and the transactions in
connection therewith, including liabilities under federal securities laws.
 
INTERESTS OF CERTAIN PERSONS IN THE MERGER
 
     In considering the recommendation of the Duracell Board of Directors with
respect to the Merger Agreement and the transactions contemplated thereby,
Duracell stockholders should be aware that certain members of Duracell
management and the Duracell Board of Directors at the time of the approval of
the Merger Agreement and the Merger had, and currently have, certain interests
which present them with conflicts of interest in connection with their
recommendation of the approval of the Merger Agreement to Duracell's
stockholders.

of the date of the Merger Agreement and bonus for fiscal year 1996, payable on
each of the first and second anniversaries of the Effective Time, provided that
the officer is still employed on the payment date. Such agreements will also
provide that if such officer's employment with Duracell is terminated other than
for cause by Duracell or for good reason by such officer within two years
following the Effective Time, he will receive (i) a payment equal to two times
the sum of such officer's annual base salary as of the date of the Merger
Agreement and bonus for fiscal year 1996, reduced by the amount of any retention
bonus already paid, payable in installments over the balance of the two-year
period following the Effective Time and (ii) until the earlier of two years
after termination or the date upon which such officer becomes re-employed with
comparable benefits, continuation of coverage and participation in current
employee benefit plans. In the case of Mr. Staves, Gillette will make an
additional payment sufficient, after giving effect to all taxes, including
interest and penalties, to make Mr. Staves whole for all taxes imposed with
respect to any excess parachute payment and any associated interest and
penalties. Such agreements will further provide that if such officer's
employment with Duracell is terminated, he will (i) execute a release of all
claims against Duracell, Gillette and their respective affiliates, (ii) not
compete in the consumer battery business in any location for a period of one
year following the termination of employment and (iii) not solicit customers or
employees of Duracell or Gillette, wherever located, during such one-year
period.
 
     Each of Robert A. Burgholzer, Jr., Vice President and Controller; Barbara
J. Johnson, Vice President, Taxes; Walter B. Rogers, Vice President, Investor
Relations; and Somerset R. Waters, Vice President and Treasurer will enter into
agreements, effective as of the Effective Time, which will provide that if such
officer's employment with Duracell is terminated other than for cause by
Duracell within two years following the Effective Time or for any reason by such
officer more than six months after the Effective Time but within two years
following the Effective Time, he or she will receive (i) a payment equal to the
sum of such officer's annual base salary as of the date of the Merger Agreement
and bonus for fiscal year 1996, payable in installments for a period of one year
following termination and (ii) until the earlier of one year after termination
or the date upon which such officer becomes re-employed with comparable
benefits, continuation of coverage and participation in current employee benefit
plans.
 
     At the Effective Time, any unvested options to purchase Duracell Common
Stock issued under the Duracell Shares Plan and the Stock Option Plan for Key
Employees will vest and become immediately exercisable. See "-- Effect on Stock
Option and Employee Benefits Plans" and "Stock Ownership of Management and
Certain Beneficial Owners of Duracell."
 
     In consideration of its advisory services to Duracell in connection with
the Merger, KKR will receive a fee of $20 million from Duracell, payable upon
consummation of the Merger. Henry R. Kravis, George R. Roberts, Paul E. Raether
and Scott M. Stuart, each of whom is a director of Duracell, are affiliates of
the entity that is the general partner of KKR, and the receipt of the entire $20
million advisory fee payable to KKR upon consummation of the Merger may
therefore be attributable to each of such persons. Because Gillette will
ultimately bear the KKR fee (which is payable only upon consummation of the
Merger), negotiations with respect to the KKR fee took place on September 11,
1996, after the principal terms of the Merger were agreed upon, between Henry R.
Kravis, on behalf of KKR, and Alfred M. Zeien, on behalf of Gillette. The fee
was based, among other things, on the role of representatives of KKR in helping
analyze various alternatives for Duracell over a period of time, in negotiating
with representatives of Gillette and in obtaining a more favorable exchange
ratio for all Duracell stockholders than was initially discussed. The directors
of Duracell who were not affiliated with KKR or with members of management
unanimously approved the KKR fee arrangement at the Board of Directors meeting
held on September 12, 1996. Prior to taking action on the KKR fee, the Duracell
Board was advised that (i) the fee arrangement between Duracell and KKR was
disclosed to and discussed with Gillette only after the principal terms of the
Merger, including the Exchange Ratio, were agreed upon by the parties, and (ii)
the aggregate investment banking and advisory fees were, on a percentage basis,
within the range of fees paid to advisors to acquired companies in recent large
transactions. See "-- Background of the Merger," "-- Opinion of Duracell's
Financial Advisor" and "Stock Ownership of Management and Certain Beneficial
Owners of Duracell."

<PAGE>   49
 
     Following consummation of the Merger, Henry R. Kravis, who is currently a
director of Duracell, will be appointed to the Gillette Board of Directors by
the directors of Gillette, which will increase the size of the Board from twelve
to thirteen directors.
 
     Gillette and the KKR Stockholders have entered into the Registration Rights
Agreement pursuant to which the KKR Stockholders may require, subject to the
terms and conditions thereof, Gillette to register the shares of Gillette Common
Stock received by them in the Merger for sale in accordance with the Securities
Act. See "Other Agreements -- Registration Rights Agreement."
 
     The Merger Agreement provides that Duracell shall, to the fullest extent
permitted under applicable law or under Duracell's Certificate of Incorporation
or By-Laws and regardless of whether the Merger becomes effective, and, after
the Effective Time, Gillette and the Surviving Corporation (as defined) shall,
to the fullest extent permitted under applicable law or the Surviving
Corporation's Certificate of Incorporation or By-Laws as in effect at the
Effective Time, indemnify and hold harmless each present and former director,
officer or employee of Duracell and its subsidiaries, against any losses,
claims, damages, costs or expenses (including attorneys' fees), judgments,
fines, liabilities and amounts paid in settlement in connection with any claim,
action, suit, proceeding or investigation, whether civil, criminal,
administrative or investigative, arising out of or pertaining to the
transactions contemplated by the Merger Agreement, or otherwise with respect to
any acts or omissions occurring at or prior to the Effective Time, to the same
extent as provided in Duracell's Certificate of Incorporation or By-Laws or any
applicable contract or agreement as in effect on the date of the Merger
Agreement, in each case for a period of six years after the date of the Merger
Agreement. The Merger Agreement provides that Gillette and the Surviving
Corporation will honor and fulfill the obligations of Duracell under
indemnification agreements with Duracell's directors and officers existing at or
before the Effective Time. The Merger Agreement further provides that Gillette
will cause the Surviving Corporation to maintain directors' and officers'
liability insurance policies as currently maintained by Duracell for six years
after the Effective Time to the extent that such policies are obtainable at an
annual cost of not greater than 150% of Duracell's annual premium as of the date
of the Merger Agreement; provided that if such coverage is not available for
such amount, Gillette or the Surviving Corporation shall purchase as much
coverage as possible for such amount. See "The Merger Agreement -- Additional
Agreements -- Indemnification and Insurance."
 
CERTAIN UNITED STATES FEDERAL INCOME TAX CONSEQUENCES
 
     The obligations of Gillette and Duracell to consummate the Merger are
conditioned on the receipt by Gillette of an opinion from Ropes & Gray, its
counsel, and the receipt by Duracell of an opinion from Simpson Thacher &
Bartlett, its counsel, that the Merger constitutes a reorganization under
Section 368 of the Internal Revenue Code of 1986, as amended (the "Code"). No
ruling has been sought from the Internal Revenue Service as to the United States
Federal income tax consequences of the Merger, and the opinions of counsel will
not be binding upon the Internal Revenue Service or any court.
 
     The opinions of counsel will be based in part upon representations, made as
of the Effective Time by Duracell, Gillette and the KKR Stockholders, which
counsel will assume to be true, correct and complete. If the representations are
inaccurate, the opinions of counsel could be adversely affected.
 
     The opinions of counsel will state that the material United States Federal
income tax consequences of the Merger are as follows:
 
          1. No gain or loss will be recognized by a Duracell stockholder upon
     the exchange of his or her Duracell Common Stock for Gillette Common Stock,
     except that a Duracell stockholder who receives cash proceeds in lieu of a
     fractional share interest in Gillette Common Stock will recognize gain or
     loss equal to the difference between such proceeds and the tax basis
     allocated to the fractional share interest. Such gain or loss will
     constitute capital gain or loss if such stockholder's Duracell Common Stock
     is held as a capital asset at the Effective Time and will be long-term
     capital gain or loss if such stockholder's Duracell Common Stock has been
     held for more than one year at the Effective Time.
 
                                       40
<PAGE>   50
 
          2. The tax basis of the Gillette Common Stock received by a Duracell
     stockholder will be the same as such stockholder's tax basis in the
     Duracell Common Stock surrendered in exchange therefor, decreased by the
     tax basis allocated to any fractional share interest exchanged for cash.
 
          3. The holding period of the Gillette Common Stock received by a
     Duracell stockholder will include the period during which the Duracell
     Common Stock surrendered in exchange therefor was held (provided that such
     Duracell Common Stock was held by such Duracell stockholder as a capital
     asset at the Effective Time).
 
          4. No gain or loss will be recognized by Duracell, Gillette or Merger
     Sub as a result of the Merger.
 
     Certain noncorporate Duracell stockholders may be subject to backup
withholding at a rate of 31% on cash payments received in lieu of a fractional
share interest in Gillette Common Stock. Backup withholding will not apply,
however, to a stockholder who (i) furnishes a correct taxpayer identification
number ("TIN") and certifies that he or she is not subject to backup withholding
on the substitute Form W-9 included in the Transmittal Letter, (ii) provides a
certificate of foreign status on Form W-8, or (iii) is otherwise exempt from
backup withholding. A stockholder who fails to provide the correct TIN on Form
W-9 may be subject to a $50 penalty imposed by the Internal Revenue Service.
 
     Each Duracell stockholder will be required to retain records and file with
such holder's U.S. federal income tax return a statement setting forth certain
facts relating to the Merger.
 
     THE FOREGOING DISCUSSION IS INTENDED ONLY AS A SUMMARY OF CERTAIN UNITED
STATES FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER AND DOES NOT PURPORT TO BE
A COMPLETE ANALYSIS OF ALL POTENTIAL TAX EFFECTS RELEVANT TO A DECISION WHETHER
DURACELL STOCKHOLDERS SHOULD VOTE IN FAVOR OF THE DURACELL MERGER PROPOSAL OR
WHETHER GILLETTE STOCKHOLDERS SHOULD VOTE IN FAVOR OF THE GILLETTE SHARE
PROPOSAL. THE DISCUSSION DOES NOT ADDRESS THE TAX CONSEQUENCES THAT MAY BE
RELEVANT TO A PARTICULAR DURACELL STOCKHOLDER SUBJECT TO SPECIAL TREATMENT UNDER
CERTAIN UNITED STATES FEDERAL INCOME TAX LAWS, SUCH AS DEALERS IN SECURITIES,
FINANCIAL INSTITUTIONS, INSURANCE COMPANIES, CERTAIN RETIREMENT PLANS,
TAX-EXEMPT ORGANIZATIONS, NON-UNITED STATES PERSONS AND STOCKHOLDERS WHO
ACQUIRED DURACELL COMMON STOCK PURSUANT TO THE EXERCISE OF DURACELL OPTIONS OR
OTHERWISE AS COMPENSATION, AND DOES NOT ADDRESS ANY CONSEQUENCES ARISING UNDER
THE LAWS OF ANY STATE, LOCALITY OR FOREIGN JURISDICTION. MOREOVER, THE TAX
CONSEQUENCES TO HOLDERS OF DURACELL OPTIONS ARE NOT DISCUSSED. THE DISCUSSION IS
BASED UPON THE CODE, TREASURY REGULATIONS THEREUNDER AND ADMINISTRATIVE RULINGS
AND COURT DECISIONS AS OF THE DATE HEREOF. ALL OF THE FOREGOING ARE SUBJECT TO
CHANGE, AND ANY SUCH CHANGE COULD AFFECT THE CONTINUING VALIDITY OF THIS
DISCUSSION. DURACELL STOCKHOLDERS ARE URGED TO CONSULT THEIR OWN TAX ADVISORS
CONCERNING THE FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES OF THE MERGER
TO THEM.
 
ANTICIPATED ACCOUNTING TREATMENT
 
     The Merger is expected to qualify as a "pooling of interests" for
accounting and financial reporting purposes. Under this method of accounting,
the recorded assets and liabilities of Gillette and Duracell will be carried
forward to the combined corporation at their recorded amounts, subject to any
adjustments required to conform the accounting policies of the two companies;
income of the combined corporation will include income of Gillette and Duracell
for the entire fiscal year in which the Merger occurs; and the reported income
of the separate corporations for prior periods will be combined and restated as
income of the combined corporation.
 
                                       41
<PAGE>   51
 
     The Merger Agreement provides that a condition to the consummation of the
Merger is the receipt of letters from KPMG Peat Marwick LLP and Deloitte &
Touche LLP, independent certified public accountants of Gillette and Duracell,
respectively, to the effect that the Merger qualifies for "pooling of interests"
accounting treatment.
 
EFFECT ON STOCK OPTION AND EMPLOYEE BENEFITS PLANS
 
     At the Effective Time, each then outstanding option to purchase Duracell
Common Stock granted under the Duracell Stock Option Plans will be deemed
assumed by Gillette and will be deemed to constitute an option to acquire, on
the same terms and conditions as were applicable under such option prior to the
Effective Time, the number of shares of Gillette Common Stock which such option
holder would have been entitled to receive pursuant to the Merger had such
holder exercised such option in full immediately prior to the Effective Time
(without regard to vesting requirements) at a price per share equal to (x) the
aggregate exercise price for Duracell Common Stock otherwise purchasable
pursuant to such option divided by (y) the number of shares of Gillette Common
Stock deemed purchasable pursuant to such option. See "The Merger
Agreement -- Terms of the Merger -- Stock Options." As of November 1, 1996,
there were outstanding options to acquire 1,001,057 shares of Duracell Common
Stock under the Stock Option Plan for Key Employees of Duracell and options to
acquire 4,668,758 shares of Duracell Common Stock under the Duracell Shares
Plan. At the Effective Time, any unvested options to purchase Duracell Common
Stock issued under the Duracell Stock Option Plans will vest and become
immediately exercisable.
 
     The Merger Agreement provides for Gillette to maintain certain Duracell
contractual benefit programs and for Duracell to enter into certain severance
plans and agreements as of the Effective Time. See "-- Interests of Certain
Persons in the Merger" and "The Merger Agreement -- Additional Agreements --
Employment and Benefit Matters."
 
CERTAIN LEGAL MATTERS
 
     Antitrust.  Pursuant to the requirements of the Hart-Scott-Rodino Antitrust
Improvements Act of 1976, as amended (the "HSR Act"), Gillette and Duracell have
each filed a Notification and Report Form for review under the HSR Act with the
Federal Trade Commission and the Antitrust Division of the Department of
Justice. The waiting period applicable to the consummation of the Merger under
the HSR Act has expired.
 
     Gillette and Duracell do not believe that any additional governmental
filings in the United States, other than the Certificate of Merger, are required
with respect to the Merger. Consummation of the Merger is conditioned upon,
among other things, the absence of any preliminary or permanent injunction or
other order issued by any federal or state court of competent jurisdiction which
prohibits or restricts the consummation of the Merger.
 
     Foreign Approvals.  Gillette and Duracell conduct operations in a number of
foreign countries where regulatory filings or approvals with applicable
competition and other authorities, including a filing with the Commission of the
European Communities, will be required in connection with the consummation of
the Merger. Gillette and Duracell believe that all such material filings and
approvals have been made or obtained, or will be made or obtained, as the case
may be.
 
RESALE OF GILLETTE AND DURACELL COMMON STOCK
 
     All Gillette Common Stock issued in connection with the Merger will be
freely transferable, except that any Gillette Common Stock received by persons
who are deemed to be "affiliates" for purposes of Rule 145 under the Securities
Act of Duracell or Gillette at the time of the Duracell Special Meeting or the
Gillette Special Meeting, respectively, may be sold by them only in transactions
permitted by the resale provisions of Rule 145 under the Securities Act with
respect to affiliates of Duracell, or Rule 144 under the Securities Act with
respect to persons who are or become affiliates of Gillette, or as otherwise
permitted under the Securities Act. Persons who may be deemed to be affiliates
of Duracell or Gillette generally include individuals or entities that control,
are controlled by, or are under common control with, such corporation and may
include certain officers and directors of such corporation as well as principal
stockholders of such corporation.
 
                                       42
<PAGE>   52
 
     Affiliates of Duracell or Gillette may not sell their shares of Gillette
Common Stock acquired in connection with the Merger, except pursuant to an
effective registration statement under the Securities Act covering such shares
or in compliance with Rule 145 (or Rule 144 under the Securities Act in the case
of persons who are or become affiliates of Gillette) or another applicable
exemption from the registration requirements of the Securities Act. In general,
under Rule 145, for two years following the Effective Time an affiliate
(together with certain related persons) would be entitled to sell shares of
Gillette Common Stock acquired in connection with the Merger only through
unsolicited "brokers' transactions" or in transactions directly with a "market
maker," as such terms are defined in Rule 144. Additionally, the number of
shares to be sold by an affiliate (together with certain related persons) within
any three-month period for purposes of Rule 145 may not exceed the greater of 1%
of the outstanding shares of Gillette Common Stock or the average weekly trading
volume of such stock during the four calendar weeks preceding such sale. Rule
145 would only remain available, however, to affiliates if Gillette remained
current with its informational filings with the Commission under the Exchange
Act. Two years after the Effective Time, a person who was an affiliate of
Duracell at the time of the Duracell Special Meeting would be able to sell
shares of Gillette Common Stock acquired in the Merger without such manner of
sale or volume limitations provided that Gillette was current with its Exchange
Act informational filings and such person was not then an affiliate of Gillette.
Three years after the Effective Time, a person who was an affiliate of Duracell
at the time of the Duracell Special Meeting would be able to sell such shares of
Gillette Common Stock acquired in the Merger without any restrictions so long as
such person had not been an affiliate of Gillette for at least three months
prior thereto.
 
     In addition, persons who are affiliates of Gillette or Duracell for
purposes of Rule 145 under the Securities Act at the time of the Gillette
Special Meeting or the Duracell Special Meeting, respectively, may be deemed to
be affiliates of Gillette or Duracell for purposes of qualifying the Merger for
pooling of interests accounting treatment under Opinion 16 of the Accounting
Principles Board and applicable SEC rules and regulations.
 
     In order to help assure compliance with Rule 145 under the Securities Act
and treatment of the Merger as a pooling of interests, each of Gillette and
Duracell has agreed to use its best efforts to cause each of its affiliates to
deliver, on or prior to the date which is 30 days prior to the Effective Time,
an agreement providing that such affiliate will not transfer (i) any Gillette
Common Stock received in the Merger except in compliance with the Securities Act
and (ii) any securities of Duracell or Gillette in the period beginning 30 days
immediately preceding the Effective Time and ending at such time as results
covering at least 30 days of combined operations of Duracell and Gillette have
been published by Gillette.
 
     Under the terms of the Registration Rights Agreement, the KKR Stockholders
have certain demand and piggyback registration rights pursuant to which they may
require, subject to the terms and conditions thereof, Gillette to register under
the Securities Act all or part of the Gillette Common Stock received by such KKR
Stockholders in connection with the Merger. See "Other
Agreements -- Registration Rights Agreement."
 
STOCK EXCHANGE LISTING
 
     It is a condition to the consummation of the Merger that the shares of
Gillette Common Stock to be issued in connection with the Merger be approved for
listing on the NYSE, subject to official notice of issuance.
 
DIVIDENDS
 
     Duracell will pay its regular quarterly cash dividend of $.29 per share of
Duracell Common Stock in the fourth calendar quarter of 1996. Gillette will pay
its regular quarterly cash dividends of $.18 per share of Gillette Common Stock
and $12.0575 per share of ESOP Preferred Stock in the fourth calendar quarter of
1996; following the Merger, it is the current intention of the Board of
Directors of Gillette to continue to declare dividends on the Gillette Stock
initially in these amounts. Future dividends will be determined by Gillette's
Board of Directors in light of the earnings and financial condition of Gillette
and its subsidiaries and other factors. See "Comparative Per Share Prices and
Dividends."
 
                                       43
<PAGE>   53
 
APPRAISAL RIGHTS
 
     Holders of Duracell Common Stock are not entitled to dissenters' appraisal
rights under Delaware law in connection with the Merger because the Duracell
Common Stock was listed on the NYSE on the Record Date for the Duracell Special
Meeting and the shares of Gillette Common Stock which such holders will be
entitled to receive in the Merger will be listed on the NYSE at the Effective
Time. Holders of Gillette Common Stock are not entitled to dissenters' appraisal
rights under Delaware law in connection with the Merger because Gillette is not
a constituent corporation in the Merger.
 
FEES AND EXPENSES
 
     The Merger Agreement requires Duracell to pay Gillette a fee (the "Fee") of
$150 million plus reasonable, documented out-of-pocket expenses of up to $15
million if the Merger Agreement is terminated under certain circumstances. See
"The Merger Agreement -- Termination."
 
     Except for the aforesaid Fee and expenses, and except for printing and
filing fees in respect of this Joint Proxy Statement/Prospectus and the
Registration Statement, which will be shared equally, each of Gillette and
Duracell will pay its own expenses in connection with the Merger.

                              THE MERGER AGREEMENT
 
     The description of the Merger Agreement contained in this Joint Proxy
Statement/Prospectus, while containing all material provisions of the Merger
Agreement, does not purport to be complete and is qualified in its entirety by
reference to the Merger Agreement, which is attached as Annex A to this Joint
Proxy Statement/Prospectus and is incorporated herein by reference.
 
TERMS OF THE MERGER
 
     The Merger.  At the Effective Time and subject to and upon the terms and
conditions of the Merger Agreement and the Delaware General Corporation Law
("DGCL"), Merger Sub will be merged with and into Duracell, the separate
corporate existence of Merger Sub will cease, and Duracell will continue as the
surviving corporation ("Surviving Corporation") and a wholly-owned subsidiary of
Gillette.
 
     Effective Time.  As promptly as practicable after the satisfaction or
waiver of the conditions to the Merger set forth in the Merger Agreement, the
Merger will be consummated by filing a certificate of merger, together with any
required related certificates, with the Secretary of State of the State of
Delaware in accordance with the relevant provisions of the DGCL. The time of
such filing is referred to as the "Effective Time."
 
     Certificate of Incorporation and By-Laws.  The Merger Agreement provides
that the Certificate of Incorporation of Duracell, as in effect immediately
prior to the Effective Time, will be the Certificate of Incorporation of the
Surviving Corporation until thereafter amended in accordance with the DGCL and
such Certificate of Incorporation, and the By-Laws of Duracell, as in effect
immediately prior to the Effective Time, will be the By-Laws of the Surviving
Corporation until thereafter amended in accordance with the DGCL, such
Certificate of Incorporation and such By-Laws; provided that the Board of
Directors of the Surviving Corporation will consist of the same number of
directors as the number of directors of Merger Sub at the Effective Time.
 
     Directors and Officers.  The directors of Merger Sub immediately prior to
the Effective Time shall be the initial directors of the Surviving Corporation,
each to hold office in accordance with the Certificate of Incorporation and
By-Laws of the Surviving Corporation, and the officers of Duracell immediately
prior to the Effective Time shall be the initial officers of the Surviving
Corporation, in each case until their respective successors are duly elected or
appointed and qualified.
 
     Conversion of Duracell Common Stock in the Merger.  At the Effective Time,
each share of Duracell Common Stock (a "Duracell Share") issued and outstanding
immediately prior to the Effective Time (excluding shares referred to in the
following paragraph) will be converted into the right to receive 0.904 shares of
validly issued, fully paid and nonassessable shares ("Gillette Shares") of
Gillette Common Stock (together with the preferred stock purchase right attached
thereto). Cash will be paid to Duracell stockholders in lieu of fractional
shares of Gillette Common Stock and for any dividends or other distributions to
which such holders are entitled. See "-- Terms of Merger -- Fractional Shares"
and "-- Exchange of Certificates."
 
     Each share of Duracell Common Stock held in the treasury of Duracell and
each share of Duracell Common Stock owned by Gillette, Merger Sub or any direct
or indirect wholly owned subsidiary of Duracell or Gillette immediately prior to
the Effective Time will, 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 therefore and cease to exist.
 
     Stock Options.
 
     (i) At the Effective Time, each outstanding option to purchase Duracell
Common Stock (a "Stock Option") granted under (A) the Duracell Shares Plan, or
(B) Duracell's Stock Option Plan for Key Employees (collectively, the "Duracell
Stock Option Plans"), whether vested or unvested, shall be deemed assumed by
Gillette 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 to the nearest whole number) of Gillette Shares as the
holder of such Stock Option would have been entitled to receive pursuant to
 
                                       45
<PAGE>   55
 
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 equal to (x) the aggregate exercise
price for Duracell Common Stock otherwise purchasable pursuant to such Stock
Option divided by (y) the number of Gillette Shares deemed purchasable pursuant
to such Stock Option.
 
     (ii) As soon as practicable after the Effective Time, Gillette 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 antidilution
provisions).
 
     (iii) Gillette shall take all corporate action necessary to reserve for
issuance a sufficient number of Gillette Shares for delivery pursuant to the
terms set forth under "-- Terms of Merger -- Stock Options."
 
     (iv) Subject to any applicable limitations under the Securities Act of
1933, as amended, and the rules and regulations thereunder (the "Securities
Act"), Gillette shall either (A) file a Registration Statement on Form S-8 (or
any successor form), effective as of the Effective Time, with respect to the
shares of Gillette Common Stock issuable upon exercise of the Stock Options, or
(B) file any necessary amendments to the Duracell's previously-filed
Registration Statement(s) on Form S-8 in order that Gillette will be deemed a
"successor registrant" thereunder, and, in either event Gillette shall use all
reasonable efforts to maintain the effectiveness of such registration
statement(s) (and maintain the current status of the prospectus or prospectuses
relating thereto) for so long as such options shall remain outstanding.
 
     Adjustments to Exchange Ratio.  The Exchange Ratio shall be adjusted to
reflect fully the effect of any stock split, reverse split, stock dividend
(including any dividend or distribution of securities convertible into Gillette
Common Stock or Duracell Common Stock), reorganization, recapitalization or
other like change with respect to Gillette Common Stock or Duracell Common Stock
occurring after the date of the Merger Agreement and prior to the Effective
Time.
 
     Fractional Shares.  No certificates or scrip representing less than one
Gillette Share shall be issued in connection with the Merger. In lieu of any
such fractional share, each holder of a certificate or certificates representing
Duracell Shares ("Certificates") who would otherwise have been entitled to a
fraction of a Gillette Share upon surrender of Certificates for exchange shall
be paid upon such surrender cash equal to the product of (i) such fraction,
multiplied by (ii) the closing price per share on the NYSE of Gillette Common
Stock as reported in the Eastern Edition of the Wall Street Journal on the
trading date prior to the date on which the Effective Time occurs.
 
EXCHANGE OF CERTIFICATES
 
     Exchange Agent.  At or prior to the Effective Time, Gillette shall supply,
or shall cause to be supplied, to or for the account of The First National Bank
of Boston, or such other bank or trust company as shall be designated by
Gillette (the "Exchange Agent"), in trust for the benefit of the holders of
Duracell Common Stock, for exchange in accordance with the Merger Agreement,
through the Exchange Agent, certificates evidencing the Gillette Shares issuable
in exchange for outstanding Duracell Shares. Gillette will make available to the
Exchange Agent from time to time as needed, cash sufficient to pay cash in lieu
of fractional shares and any dividends and distributions.
 
     Exchange Procedures.  As soon as reasonably practicable after the Effective
Time, Gillette will instruct the Exchange Agent to mail to each holder of record
of Duracell Common Stock a letter of transmittal and instructions to effect the
surrender of the certificates representing Duracell Common Stock in exchange for
certificates evidencing Gillette Common Stock. Upon surrender of a certificate
representing Duracell Common Stock for cancellation to the Exchange Agent
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 will be entitled to receive in exchange therefor (i)
certificates evidencing that number of whole Gillette Shares which such holder
has the right to receive in the Merger, (ii) any dividends or other
distributions on the shares of Gillette Common Stock which such holder is
entitled to receive, and (iii) cash in respect of fractional shares of Gillette
Common Stock (the Gillette Shares, dividends, distributions and cash being,
collectively, the "Merger Consideration"), and the certificate representing
Duracell Common Stock so
 
                                       46
<PAGE>   56
 
surrendered shall forthwith be canceled. In the event of a transfer of ownership
of Duracell Shares which is not registered in the transfer records of Duracell
as of the Effective Time, Gillette Shares, dividends and distributions may be
issued and paid to a transferee if the certificate evidencing such Duracell
Shares is presented to the Exchange Agent, accompanied by all documents required
to evidence and effect such transfer and by evidence that any applicable stock
transfer taxes have been paid. Until so surrendered, each outstanding
certificate that, prior to the Effective Time, represented shares of Duracell
Common Stock will be deemed from and after the Effective Time, for all corporate
purposes (other than payment of dividends and subject to the provisions
described below under "-- Exchange of Certificates -- No Liability, Escheat and
Withholding"), to evidence the ownership of the number of full Gillette Shares
into which such Duracell Shares shall have been so converted.
 
     Distributions With Respect to Unexchanged Duracell Common Stock.  No
dividends or other distributions declared or made after the Effective Time with
respect to Gillette Common Stock with a record date after the Effective Time
will be paid to the holder of an unsurrendered certificate representing shares
of Duracell Common Stock with respect to the shares of Gillette Common Stock
they are entitled to receive until the holder of such certificate shall
surrender such certificate. Subject to applicable law and the provisions
described below under "-- Exchange of Certificates -- No Liability, Escheat and
Withholding," following surrender of any certificate representing shares of
Duracell Common Stock, there will be paid to the record holder of the
certificates representing whole shares of Gillette Common Stock issued in
exchange therefor, without interest, at the time of 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 Gillette Common Stock.
 
     Transfers of Ownership.  If any certificate for shares of Gillette Common
Stock is to be issued in a name other than that in which the certificate
representing shares of Duracell Common Stock surrendered in exchange therefor is
registered, it will be a condition of the issuance that the certificate
surrendered will be properly endorsed and otherwise in proper form for transfer
and that the person requesting such exchange will have paid to Gillette or any
designated agent any transfer or other taxes required by reason of the issuance
of a certificate for shares of Gillette Common Stock in any name other than that
of the registered holder of the certificate surrendered, or have established to
the satisfaction of Gillette or any designated agent that such tax has been paid
or is not payable.
 
     No Liability, Escheat and Withholding.  At any time following one year
after the Effective Time, Gillette shall be entitled to require the Exchange
Agent to deliver to Gillette any Merger Consideration which has been made
available to the Exchange Agent by or on behalf of Gillette and which has not
been disbursed to holders of certificates representing shares of Duracell Common
Stock, and thereafter such holders shall be entitled to look to Gillette only as
general creditors thereof with respect to the Merger Consideration payable upon
due surrender of such certificates. Notwithstanding the foregoing, neither
Gillette, Merger Sub nor Duracell will be liable to any holder of Duracell
Common Stock for any Merger Consideration delivered to a public official
pursuant to any applicable abandoned property, escheat or similar law. Gillette
or the Exchange Agent will be entitled to deduct and withhold from the Merger
Consideration otherwise payable to any Duracell stockholder such amounts as
Gillette or the Exchange Agent is required to deduct and withhold with respect
to the making of such payment under any provision of federal, state, local or
foreign tax law.
 
     Lost, Stolen or Destroyed Certificates.  In the event any certificates
representing shares of Duracell Common Stock have been lost, stolen or
destroyed, the Exchange Agent will issue shares of Gillette Common Stock in
exchange for such lost, stolen or destroyed certificates upon the making of an
affidavit of that fact by the owner of such certificates and delivery of a bond
in a reasonable sum as indemnity against any claim that may be made against
Gillette or the Exchange Agent with respect to the certificates alleged to have
been lost, stolen or destroyed.

     reserved against in Duracell's financial statements contained in reports
     filed prior to the date of the Merger Agreement with the Commission or
     incurred in the ordinary course of business and consistent with past
     practice; or
 
          (x) take, or agree to take, any of the foregoing actions or any action
     which would make any of the representations or warranties of Duracell
     contained in the Merger Agreement untrue or incorrect or prevent Duracell
     from performing its covenants under the Merger Agreement.
 
     No Solicitation by Duracell.  The Merger Agreement provides that Duracell
will not, directly or indirectly, through any officer, director, employee,
representative or agent of Duracell or any of its subsidiaries, (i) solicit,
initiate or encourage the initiation of any inquiries or proposals regarding any
merger, sale of substantial assets, sale of shares of capital stock (including,
without limitation, by way of a tender offer) or similar transactions involving
Duracell or any subsidiaries of Duracell other than the Merger (the foregoing
being referred to as "Acquisition Proposals"), (ii) engage in negotiations or
discussions concerning, or provide any nonpublic information to any person
relating to, any Acquisition Proposal or (iii) agree to, approve or recommend
any Acquisition Proposal. However, the Board of Directors of Duracell is not (i)
prevented from considering, negotiating, discussing, approving and recommending
to the stockholders of Duracell a bona fide Acquisition Proposal not solicited
in violation of the Merger Agreement, provided the Board of Directors of
Duracell determines in good faith and upon advice of outside counsel that it is
required to do so in order to discharge properly its fiduciary duties or (ii)
prohibited from complying with Rule 14e-2 promulgated under the Exchange Act
with regard to a tender or exchange offer.
 
     Under the Merger Agreement, Duracell is required immediately to notify
Gillette after receipt of any Acquisition Proposal, or any modification of or
amendment to any Acquisition Proposal, or any request for nonpublic information
relating to Duracell or any of its subsidiaries in connection with an
Acquisition Proposal or for access to the properties, books or records of
Duracell or any subsidiary by any person or entity that
 
                                       50
<PAGE>   60
 
informs the Board of Directors of Duracell or such subsidiary that it is
considering making, or has made, an Acquisition Proposal.
 
     If the Board of Directors of Duracell receives a request for material
nonpublic information by a person who makes a bona fide Acquisition Proposal,
and the Board of Directors determines in good faith and upon the advice of
outside counsel that it is required to cause Duracell to provide such
information in order to discharge properly the directors' fiduciary duties,
then, provided the person making the Acquisition Proposal has executed a
confidentiality agreement substantially similar to the one then in effect
between Duracell and Gillette (other than for the provisions relating to
exclusivity and standstill), Duracell may provide such person with access to
information regarding Duracell.
 
     The Merger Agreement also provides that Duracell will not release any third
party from the confidentiality provisions of any confidentiality agreement to
which Duracell is a party.
 
     Duracell is required to ensure that the officers, directors and employees
of Duracell and its subsidiaries and any investment banker or other advisor or
representative retained by Duracell are aware of the foregoing restrictions.
 
     Conduct of Business by Gillette.  The Merger Agreement provides that, prior
to the Effective Time, unless Duracell otherwise agrees in writing, Gillette
will conduct its business, and cause the businesses of its subsidiaries to be
conducted, in the ordinary course of business and consistent with past practice,
other than actions taken by Gillette or its subsidiaries in contemplation of the
Merger, and Gillette shall use all reasonable efforts to preserve substantially
intact the business organization of Gillette and its subsidiaries, to keep
available all services of the present officers, employees and consultants of
Gillette and its subsidiaries and to preserve the present relationships of
Gillette and its subsidiaries with customers, suppliers and other persons with
which Gillette or any of its subsidiaries has significant business relations.
Except as contemplated by the Merger Agreement, neither Gillette nor any of its
subsidiaries, without the prior written consent of Duracell, will:
 
          (a) declare, set aside, make or pay any dividend or other distribution
     (whether in cash, stock or property or any combination thereof) in respect
     of any of its capital stock, other than regular quarterly cash dividends
     consistent with past practices and except that a wholly-owned subsidiary of
     Gillette may declare and pay a dividend to its parent;
 
          (b) take or agree in writing or otherwise to take any action which
     would make any of the representations or warranties of Gillette contained
     in the Merger Agreement untrue or incorrect or prevent Gillette from
     performing or cause Gillette not to perform its covenants under the Merger
     Agreement; or
 
          (c) amend or otherwise change the Certificate of Incorporation or
     By-Laws of Gillette in a manner that would be materially adverse to the
     holders of Gillette Common Stock (it being understood that any such
     amendment made to implement a so-called "shareholder rights plan" as
     described in the footnotes to the financial statements included in or
     incorporated by reference into the Annual Report of Gillette on Form 10-K
     for the fiscal year ended December 31, 1995 shall not be deemed to be
     materially adverse to the holders of Gillette Common Stock).

afford to the officers, employees, accountants, counsel and other
representatives of the other, reasonable access, during the period prior to the
Effective Time, to all its properties, books, contracts, commitments and records
and, during such period, Duracell and Gillette each shall (and shall cause each

authorization, execution and delivery of the Merger Agreement and the
consummation by them of the transactions contemplated thereby, in each case, as
promptly as practicable.
 
     Affiliate Agreements.  Each of Gillette and Duracell will use its best
efforts to cause each of its affiliates to deliver, on or prior to the date
which is 30 days prior to the Effective Time, an agreement (an "Affiliate
Agreement") providing that (i) such affiliate will not transfer any Gillette

any securities of Duracell or Gillette.
 
     Indemnification and Insurance.  The Merger Agreement provides that the
By-Laws of the Surviving Corporation will contain the provisions with respect to
indemnification set forth in the By-Laws of Duracell, which will not be amended,
repealed or otherwise modified for a period of six years from the Effective Time
in any manner that would adversely affect the rights thereunder of individuals
who at the Effective Time were directors, officers, employees or agents of
Duracell, unless such modification is required by law.
 
     The Merger Agreement provides that Duracell, to the fullest extent
permitted under applicable law or under Duracell's Certificate of Incorporation
or By-Laws and regardless of whether the Merger becomes effective, indemnify and
hold harmless, and after the Effective Time, Gillette and the Surviving
Corporation will, to the fullest extent permitted under applicable law or under
the Surviving Corporation's Certificate of Incorporation or By-Laws as in effect
at the Effective Time, indemnify and hold harmless, each present and former
director, officer or employee of Duracell or any of its subsidiaries
(collectively, the "Indemnified Parties") against any costs or expenses
(including attorneys' fees), 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, arising out of or pertaining to the transactions contemplated by
the Merger Agreement, or otherwise with respect to any acts or omissions
occurring at or prior to the Effective Time, to the same extent as provided in
Duracell's Certificate of Incorporation or By-Laws or any applicable contract or
agreement as in effect on the date of the Merger Agreement, in each case for a
period of six years after the date of the Merger Agreement. In the event of any
such claim, action, suit, proceeding or investigation (whether arising before or
after the Effective Time), (i) any counsel retained by the Indemnified Parties
for any period after the Effective Time shall be reasonably satisfactory to the
Surviving Corporation, (ii) after the Effective Time, the Surviving Corporation
shall pay the reasonable fees and expenses of such counsel, promptly after
statements therefor are received, and (iii) the Surviving Corporation will
cooperate in the defense of any such matter; provided, however, that the
Surviving Corporation shall not be liable for any settlement effected without
its written consent (which consent shall not be unreasonably withheld); and
provided, further, that, in the event that any claim or claims for
indemnification are asserted or made within such six-year period, all rights to
indemnification in respect of any such claim or claims shall continue until the
disposition of any and all such claims. The Indemnified Parties as a group may
retain only one law firm to represent them with respect to any single action
unless there is, under applicable standards of professional conduct, a conflict
on any significant issue between the positions of any two or more Indemnified
Parties.
 
     Gillette and the Surviving Corporation shall honor and fulfill in all
respects the obligations of Duracell pursuant to indemnification agreements with
the Duracell's directors and officers existing at or before the Effective Time.
 
     For a period of six years after the Effective Time, Gillette shall cause
the Surviving Corporation to maintain in effect, if available, directors' and
officers' liability insurance covering those persons who are currently covered
by Duracell's directors' and officers' liability insurance policy (a copy of
which has been made available to Gillette) on terms comparable to those now
applicable to directors and officers of Duracell; provided, however, that in no
event shall Gillette or the Surviving Corporation be required to expend in
excess of 150% of the annual premium currently paid by Duracell for such
coverage; and provided further, that if the premium for such coverage exceeds
such amount, Gillette or the Surviving Corporation shall purchase a policy with
the greatest coverage available for such 150% of the annual premium.

Plan") other than severance plans and agreements for which those provided in a
separate schedule to the Merger Agreement shall be substituted; provided,
however, that nothing therein shall affect Gillette's rights to modify or
terminate any such Benefit Plan at or after the end of such one year period. On
and after the Effective Time, employees of the Surviving Corporation who were
employees at the Effective

Time will be eligible to participate in Gillette's stock option and annual
incentive plans as in effect from time to time at levels commensurate with their
responsibilities and consistent with the terms of such plans.
 
     (ii) Effective no later than the Effective Time, Duracell shall enter into
agreements and adopt plans or programs in forms satisfactory to Gillette, the
terms and conditions of which shall be consistent in all material respects with
those set forth in a schedule to the Merger Agreement to provide in a manner
consistent with the transaction contemplated thereby the benefits and payments
to each person or category of persons identified in such schedule to the Merger
Agreement. See "The Merger -- Interests of Certain Persons in the Merger."
 
     Notification of Certain Matters.  Duracell and Gillette will each give the
other prompt notice of the occurrence of any event which would be likely to
cause any representation or warranty of the notifying party contained in the
Merger Agreement to be materially untrue or inaccurate, or any failure of the
notifying party materially to comply with or satisfy any covenant, condition or
agreement in the Merger Agreement.
 
     Further Action; Tax Treatment.  Each of the parties to the Merger Agreement
agrees to use all reasonable efforts to take all actions and do other things
necessary, proper or advisable to consummate and make effective as promptly as
practicable the transactions contemplated by the Merger Agreement, to obtain in
a timely manner all necessary waivers, consents and approvals and to effect all
necessary registrations and filings, and otherwise to satisfy or cause to be
satisfied all conditions precedent to its obligations under the Merger
Agreement. Each of Gillette, Merger Sub and Duracell 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 to its knowledge could reasonably be
expected to prevent the Merger from qualifying, as a reorganization under the
provisions of Section 368 of the Code.
 
     Public Announcements.  Gillette and Duracell have agreed to consult with
each other before issuing any press release with respect to the Merger or the
Merger Agreement and will not issue any such press release or make any such
public statement without the prior consent of the other party, which consent
will not be unreasonably withheld, except as required by law or the regulations
of the NYSE.
 
     NYSE Listing; Listing of Gillette Shares.  Duracell shall use its best
efforts to continue the listing of Duracell Common Stock on the NYSE during the
term of the Merger Agreement. Gillette shall use its best efforts to cause the
Gillette Shares to be issued in the Merger to be approved for listing, upon
official notice of issuance, on the NYSE.
 
     Accountant's Letters.  Upon reasonable notice from the other, Duracell or
Gillette will use their respective best efforts to cause Deloitte & Touche LLP
or KPMG Peat Marwick LLP, respectively, to deliver to Gillette or Duracell, as
the case may be, a letter, dated within 2 business days of the effective date of
the Registration Statement covering such matters as are requested by Gillette or
Duracell, as the case may be, and as are customarily addressed in accountant's
"comfort" letters.
 
     Pooling Accounting Treatment.  Each of Gillette and Duracell agrees not to
take any action that to its knowledge could reasonably be expected to adversely
affect the ability of Gillette to treat the Merger as a pooling of interests,
and each of Gillette and Duracell agrees to take such action as may be
reasonably required to negate the impact of any past actions which to its
knowledge could reasonably be expected to adversely impact the ability of
Gillette to treat the Merger as a pooling of interests.

     Conditions to Termination.  The Merger Agreement may be terminated at any

          (i) by mutual written consent duly authorized by the Boards of
     Directors of Gillette and Duracell; or
 
          (ii) by either Gillette or Duracell if the Merger shall not have been
     consummated by March 31, 1997 (provided that such right to terminate the
     Merger Agreement shall 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); or
 
          (iii) by either Gillette or Duracell if a court of competent
     jurisdiction or governmental, regulatory or administrative agency or
     commission shall have issued a nonappealable final order, decree or ruling
     or taken any other action having the effect of permanently restraining,
     enjoining or otherwise prohibiting the Merger (provided that such right to

          (iv) (1) by Gillette, if the requisite vote of the stockholders of
     Duracell shall not have been obtained at a duly held meeting of such
     stockholders or any adjournment thereof by March 31, 1997 or (2) by
     Duracell, if the requisite vote of the stockholders of Gillette shall not
     have been obtained at a duly held meeting of such stockholders or any
     adjournment thereof by March 31, 1997; or
 
          (v) by Gillette or Duracell, if: (1) the Board of Directors of

     have resolved to do so in accordance with the provisions described above
     under "-- Additional Agreements -- Stockholders Meetings"; (2) the Board of
     Directors of Duracell shall have recommended to the stockholders of
     Duracell an Alternative Transaction (as defined below); or (3) a tender
     offer or exchange offer for 15% or more of the outstanding shares of

<PAGE>   66
 
     commenced (other than by Gillette or an affiliate of Gillette) and the
     Board of Directors of Duracell recommends that the stockholders of Duracell
     tender their shares in such tender or exchange offer; provided, that,
     Duracell shall not be entitled to exercise any termination rights under
     clause (2) or (3) of this paragraph unless (x) any action of the Board of
     Directors of Duracell referred to in either such clause is required to be
     taken by the Board of Directors in order to properly discharge its
     fiduciary duties and (y) Duracell has complied with its obligations
     described under "-- Conduct of Business Pending the Merger -- No
     Solicitation by Duracell"; or
 
          (vi) by Duracell, if the Board of Directors of Gillette shall
     withdraw, modify or change its approval or recommendation of the Merger
     Agreement or the Merger in a manner adverse to Duracell or shall have
     resolved to do so in accordance with the provisions described above under
     "-- Additional Agreements -- Stockholders Meetings."
 
     As used herein, "Alternative Transaction" means any of (1) a transaction or
series of transactions pursuant to which any person (or group of persons) other
than Gillette or its subsidiaries and other than KKR and its affiliates (a
"Third Party") acquires or would acquire more than 15% of the outstanding shares
of Duracell Common Stock, whether from Duracell or pursuant to a tender offer or
exchange offer or otherwise, (2) any acquisition or proposed acquisition of
Duracell or any of its significant subsidiaries by a merger or other business
combination (including any so-called "merger of equals" and whether or not
Duracell or any of its significant subsidiaries is the entity surviving any such
merger or business combination) or (3) any other transaction pursuant to which
any Third Party acquires or would acquire control of assets (including for this
purpose the outstanding equity securities of subsidiaries of Duracell and any
entity surviving any merger or business combination including any of them) of
Duracell or any of its subsidiaries having a fair market value equal to more
than 35% of the fair market value of all the assets of Duracell and its
subsidiaries, taken as a whole, immediately prior to such transaction.
 
     Effect of Termination.  In the event of the termination of the Merger
Agreement, the Merger Agreement shall forthwith become void and there shall be
no liability on the part of any party thereto or any of its affiliates,
directors, officers or stockholders except (1) as otherwise set forth under
"-- Termination -- Fees and Expenses" below, and (2) nothing in the Merger
Agreement shall relieve any party from liability for any breach thereof
occurring prior to termination. The Confidentiality Letter shall survive
termination of the Merger Agreement as set forth therein.
 
     Fees and Expenses.
 
     (i) Except as set forth below, all fees and expenses incurred in connection
with the Merger Agreement and the transactions contemplated thereby shall be
paid by the party incurring such expenses, whether or not the Merger is
consummated; provided, however, that Gillette and Duracell shall share equally
all fees and expenses, other than accountants' and attorneys' fees, incurred in
connection with the printing and filing of this Joint Proxy Statement/Prospectus
(including any preliminary materials related thereto) and the Registration
Statement (including financial statements and exhibits) and any amendments or
supplements thereto.
 
     (ii) The Merger Agreement requires Duracell to pay Gillette a fee of $150
million (the "Fee"), plus actual, documented and reasonable out-of-pocket
expenses of Gillette relating to the transactions contemplated by the Merger
Agreement not in excess of $15 million in the aggregate (including, but not
limited to, reasonable fees and expenses of Gillette's counsel, accountants and
financial advisers) ("Expenses"), upon the termination of the Merger Agreement
by Gillette or Duracell on the basis described under clauses (v)(2) and (3) of
"-- Termination -- Conditions to Termination" above.
 
     (iii) The Merger Agreement requires Duracell to pay Gillette the Fee plus
the Expenses if all of the following events have occurred:
 
          (1) a bona fide Alternative Transaction is publicly commenced,
     publicly disclosed, publicly proposed or publicly communicated to Duracell
     at any time on or after the date of the Merger Agreement and on or prior to
     the date of the meeting of the stockholders of Duracell (including the last
     date on which any adjourned session thereof is reconvened);
 
                                       57
<PAGE>   67
 
          (2) either Gillette or Duracell terminates the Merger Agreement
     pursuant to the section of the Merger Agreement described under clause (ii)
     of "-- Termination -- Conditions to Termination" above or Gillette
     terminates the Merger Agreement pursuant to the section of the Merger
     Agreement described under clause (iv)(1) of "-- Termination -- Conditions
     to Termination" above if, in the case of termination under either such
     clause, the requisite vote for approval and adoption of the Merger
     Agreement by the stockholders of Duracell shall not have been obtained by
     March 31, 1997; and
 
          (3) thereafter on or prior to the second anniversary of the date of
     termination, (A) such Alternative Transaction is consummated or (B) there
     is consummated any transaction, whether or not commenced, publicly
     disclosed, publicly proposed or communicated to Duracell prior to such
     termination, that would constitute an Alternative Transaction (provided
     that for purposes of this clause the reference to the percentage of
     outstanding shares of Duracell Common Stock in clause (1) of the definition
     of Alternative Transaction specified above under
     "-- Termination -- Conditions to Termination" shall be 50% instead of 15%).
 
     (iv) The Merger Agreement requires Duracell to pay Gillette the Fee plus
the Expenses if Gillette or Duracell terminates the Merger Agreement pursuant to
the section of the Merger Agreement described under clause (v)(1) of
"-- Termination -- Conditions to Termination" above and thereafter on or prior
to the second anniversary of the date of termination there is consummated a
transaction that would constitute an Alternative Transaction (provided that for
purposes of this clause, the reference to the percentage of outstanding shares
of Duracell Common Stock in clause (1) of the definition of Alternative
Transaction specified above under "-- Termination -- Conditions to Termination"
shall be 50% instead of 15%).
 
     (v) The Fee and Expenses payable pursuant to clause (ii) of this section
"-- Termination -- Fees and Expenses" shall be paid within one business day
after the first to occur of any of the events described in said clause (ii)

this section "-- Termination -- Fees and Expenses" shall be paid within one
business day following the consummation of any such Alternative Transaction.
Notwithstanding the preceding sentences, in no event shall Duracell be required
to pay any such Fee and Expenses to Gillette if, immediately prior to the
termination of the Merger Agreement, Gillette was in material breach of its
obligations under the Merger Agreement.
 
AMENDMENT AND WAIVER
 
     The Merger Agreement may be amended in writing by the parties by action
taken by or on behalf of their respective Boards of Directors at any time prior
to the Effective Time, provided that after approval of the Merger by the
stockholders of Duracell, no amendment may be made which by law requires further
approval by such stockholders without such further approval.
 
     At any time prior to the Effective Time, any party to the Merger Agreement
may, with respect to any other party, extend the time for the performance of any
of the obligations or other acts, waive any inaccuracies in the representations
and warranties contained in the Merger Agreement or in any document delivered
pursuant to the Merger Agreement, or waive compliance with any of the agreements
or conditions contained in the Merger Agreement. Any such extension or waiver
will be valid only if set forth in an instrument in writing signed by the party
or parties to be bound thereby.

                                OTHER AGREEMENTS
 
     The descriptions of the Stockholders Agreement and the Registration Rights
Agreement contained in this Joint Proxy Statement/Prospectus, while containing
all material provisions of such agreements, do not purport to be complete and
are qualified in their entirety by reference to such agreements, which are filed
as exhibits to the Registration Statement of which this Joint Proxy
Statement/Prospectus is a part.
 
STOCKHOLDERS AGREEMENT
 
     Concurrently with the execution of the Merger Agreement, Gillette and the
KKR Stockholders entered into the Stockholders Agreement. Pursuant to the
Stockholders Agreement, each of the KKR Stockholders has agreed to vote all of
the shares of Duracell it owns of record or beneficially or subsequently
acquires ("Subject Securities") in favor of the Merger and the approval of the
terms of the Merger Agreement and against other business combinations and
actions which could interfere with the Merger and has granted an irrevocable
proxy to Merger Sub, certain officers of Merger Sub and their successors and any
other designee of Merger Sub to vote the Subject Shares in accordance with such
agreement (the "Proxy"). The KKR Stockholders collectively owned 41,100,000 (or
approximately 34% of the outstanding) shares of Duracell Common Stock as of the
date of the Merger Agreement.
 
     Each KKR Stockholder has agreed that it will not, directly or indirectly,
solicit or respond to any inquiries or the making of any proposal by any person
or entity (other than Gillette or any affiliate of Gillette) with respect to
Duracell which constitutes or could reasonably be expected to lead to an
Alternative Transaction (as defined in "The Merger Agreement
- -- Termination -- Conditions to Termination"). Each KKR Stockholder has also
agreed that it will not, directly or indirectly, except pursuant to the terms of
the Merger Agreement, offer for sale, sell, or otherwise dispose of or grant any
proxies with respect to any or all of such KKR Stockholder's shares of Duracell
Common Stock.
 
     The Stockholders Agreement shall terminate upon the earlier of the
consummation of the Merger and the termination of the Merger Agreement pursuant
to its terms.
 
     Notwithstanding anything in the Stockholders Agreement to the contrary, the
covenants and agreements set forth therein shall not prevent any of the
designees of the KKR Stockholders who serve on Duracell's Board of Directors
from taking any action, subject to applicable provisions of the Merger
Agreement, while acting in such designee's capacity as a director of Duracell.
 
     In connection with the execution and delivery by the KKR Stockholders of
the Stockholders Agreement, Duracell confirmed to the KKR Stockholders that
Duracell's indemnification obligations to the KKR Stockholders and certain of
their affiliates under an agreement with the KKR Stockholders which was entered
into at the time of the acquisition of Duracell by the KKR Stockholders would be
applicable to liabilities, obligations, losses and certain other costs and
expenses arising out of their purchase or ownership of shares of Duracell Common
Stock or litigation to which they are made parties in their capacity as
stockholders or owners of securities, including certain claims that might arise
with respect to their entering into or performing their obligations under the
Stockholders Agreement.
 
REGISTRATION RIGHTS AGREEMENT
 
     Concurrently with the execution of the Merger Agreement, Gillette and the
KKR Stockholders entered into the Registration Rights Agreement.
 
     Demand Registration Rights.  Until the earlier of December 31, 2000 or such
time as the aggregate market value of the Gillette Common Stock received in the
Merger or distributed in respect thereof and owned by the KKR Stockholders is
less than $250,000,000, any KKR Stockholder or KKR Stockholders may make a
written demand that Gillette effect the registration under the Securities Act of
all or part of the shares of Gillette Common Stock issued to such KKR
Stockholder or KKR Stockholders pursuant to the Merger Agreement ("Registrable
Securities"), provided that (i) Gillette shall not be required to respond to
more than five such demands and (ii) the shares to be registered must either
have an aggregate market value of at
 
                                       59
<PAGE>   69
 
least $325,000,000 or constitute all of the remaining Registrable Securities
then outstanding. Gillette is entitled to postpone such registration for limited
periods in certain circumstances.
 
     Piggyback Registration.  If Gillette proposes to register any of its equity
securities, whether for its own account or for the account of a third party, at
any time until December 31, 2002 (subject to certain exceptions), each KKR
Stockholder may request that Gillette include any or all of their Registrable
Securities in the registration. The agreement permits Gillette to exclude shares
in certain circumstances and provides for certain priorities in registration.
 
     Certain Other Provisions.  All expenses incident to Gillette's performance
of its registration obligations under the Registration Rights Agreement,
including the reasonable fees and expenses of one counsel reasonably
satisfactory to Gillette retained in connection with each registration by the
KKR Stockholders of a majority of the Registrable Securities being registered,
will be paid by Gillette. Underwriting commissions or discounts or transfer
taxes, if any, attributable to the sale of Registrable Securities by the KKR
Stockholders will be paid by the KKR Stockholders.
 
     The Registration Rights Agreement contains customary indemnification
provisions whereby Gillette is obligated to indemnify and hold harmless the KKR
Stockholders and certain related parties, and the KKR Stockholders are obligated
under certain circumstances to indemnify and hold harmless Gillette and certain
related parties, in each case in connection with liabilities relating to the
registration of the Registrable Securities.

the earnings and financial condition of Gillette and its subsidiaries and other
factors.

                     UNAUDITED PRO FORMA CONDENSED COMBINED
                              FINANCIAL STATEMENTS
 
     The following unaudited pro forma condensed combined financial statements,
including the notes thereto, are qualified in their entirety by reference to,
and should be read in conjunction with the historical consolidated financial
statements of Gillette and Duracell, including the notes thereto, incorporated
herein by reference.
 
     The unaudited pro forma condensed combined financial statements assume a
business combination between Gillette and Duracell accounted for on a
pooling-of-interests basis and are based on each company's respective historical
audited and unaudited consolidated financial statements and notes thereto, which
are incorporated herein by reference. The unaudited pro forma condensed combined
balance sheet combines Gillette's and Duracell's consolidated condensed balance
sheets as of September 30, 1996, giving effect to the Merger as if it had
occurred on September 30, 1996.
 
     The unaudited pro forma combined condensed statements of operations combine
Gillette's historical results for the nine months ended September 30, 1996 and
September 30, 1995 and the years ended December 31, 1995, 1994 and 1993 with
Duracell's historical results for the nine months ended September 30, 1996 and
September 30, 1995, and the twelve months ended December 31, 1995, June 30, 1994
and June 30, 1993, respectively, giving effect to the Merger as if it had
occurred on January 1, 1993.
 
     As permitted by Commission regulations, Duracell's six-month period ended
December 31, 1994 has been omitted from the unaudited pro forma condensed
combined statements of operations. Duracell's Sales, Profit From Operations and
Net Income were $1,222.3 million, $287.0 million and $164.1 million,
respectively, for such six-month period. Duracell's Dividends Paid Per Common
Share during such six-month period amounted to $.44.
 
     The pro forma information is presented for illustrative purposes only and
is not necessarily indicative of the operating results or financial position
that would have occurred if the Merger had been consummated at the beginning of
the earliest period presented, nor is it necessarily indicative of future
operating results or the future financial position of Gillette.

                NOTES TO UNAUDITED PRO FORMA CONDENSED COMBINED
                              FINANCIAL STATEMENTS
 
NOTE 1.  BASIS OF PRESENTATION
 
     The unaudited pro forma condensed combined statements of operations combine
the historical statements of operations of Gillette for the nine months ended
September 30, 1996 and September 30, 1995, and the years ended December 31,
1995, 1994 and 1993 with the historical statements of operations of Duracell for
the nine months ended September 30, 1996 and 1995, and the twelve months ended
December 31, 1995, June 30, 1994 and June 30, 1993, respectively.
 
     Gillette has a fiscal year ending December 31, and Duracell has a fiscal
year ending June 30. Accordingly, the unaudited pro forma combined financial
statements for the year ended December 31, 1995 include Duracell's financial
statements conformed to Gillette's fiscal year end.
 
     No adjustments have been made in these pro forma financial statements to
conform the accounting policies of the combining companies. The nature and
extent of such adjustments, if any, are not expected to be significant.
 
     The calculation for income per share for Gillette and Duracell uses the
weighted average number of common shares outstanding. Duracell's calculation
also includes common share equivalents. The combined calculation excludes common
share equivalents.
 
NOTE 2.  PRO FORMA NET INCOME PER SHARE AND NUMBER OF SHARES OUTSTANDING
 
     The number of shares of Gillette Common Stock which will be issued in
exchange for the outstanding shares of Duracell is based on the Exchange Ratio
of .904 shares of Gillette Common Stock for each share of Duracell Common Stock
issued and outstanding immediately prior to the Effective Time. The .904
Exchange Ratio was used in preparing the pro forma combined financial data and
the following table provides the pro forma number of shares to be issued in
connection with the Merger:

          Number of shares of Gillette Common Stock outstanding after     
             completion of the Merger.....................................    554.2
                                                                              =====
</TABLE>
 
     The pro forma combined Net Income Per Common Share for the nine months
ended September 30, 1996 is based on the combined weighted average number of
common shares of Gillette and Duracell (which excludes common stock equivalents)
as of September 30, 1996 and an exchange ratio of .904 shares of Gillette Common
Stock for each issued and outstanding share of Duracell Common Stock. The actual
number of shares of Gillette Common Stock to be issued in the Merger will be
determined at the Effective Time.
 
NOTE 3.  MERGER-RELATED EXPENSES
 
     It is estimated that Merger-related costs of approximately $340.0 million
will be incurred for restructuring programs, other unusual and nonrecurring
items, and direct costs of the Merger, consisting primarily of transaction costs
for investment bankers fees, attorneys, accountants, financial printing, and
other related charges.
 
     Direct costs of the Merger are estimated at approximately $65.0 million.
The pro forma condensed combined balance sheet gives effect to direct costs of
the Merger as if they had been incurred as of
 
                                       67
<PAGE>   77
 
September 30, 1996, but the pro forma condensed combined statements of
operations do not give effect to such expenses.
 
     Estimated Merger-related costs for restructuring programs and other unusual
and nonrecurring items of approximately $275.0 million have not been recorded on
the condensed combined balance sheet because the estimate and the related
details supporting such programs and activities are preliminary and therefore
subject to change. These costs will be provided for in the ordinary course of
business of the formerly separate companies to eliminate duplicate facilities
and excess capacity, and to provide for organizational realignment and the
related work force reductions. These nonrecurring costs will be charged to
operations as incurred.
 
NOTE 4.  PRO FORMA ADJUSTMENTS
 
     Adjustments have been included in the pro forma combined condensed balance
sheet to reflect the exchange ratio described in Note 2 above.
 
     Pro forma adjustments to reflect the effect of the Merger transaction on
the pro forma condensed combined balance sheet at September 30, 1996, are as
follows:
 
     a.  Common Stock is increased by $108.2 million to record the Gillette
         Common Stock issued in the Merger and is decreased by $1.2 million to
         record the retirement of the Duracell Common Stock.
 
     b.  Duracell Earnings Reinvested in the Business and Cumulative Foreign
         Currency Translation Adjustments account balances are combined with
         Gillette account balances.
 
     c.  Duracell Treasury Stock, at cost, is retired and charged to Additional
         Paid-in Capital.
 
     d.  Combined Additional Paid-in Capital is adjusted for the effects of pro
         forma adjustments (a) and (c) above.
 
     e.  Accounts Payable and Accrued Liabilities and Earnings Reinvested in the
         Business reflect the estimated direct costs of the Merger of $65.0
         million.
 
NOTE 5.  DIVIDENDS
 
     The pro forma combined Dividends Paid Per Common Share are not necessarily
indicative of dividends to be paid to holders of Gillette Common Stock in future
periods. It is the current intention of the Gillette Board of Directors to
declare quarterly cash dividends following the Merger initially in the amount of
$.18 per share of Gillette Common Stock. Future dividends will be determined by
Gillette's Board of Directors in light of the earnings and financial condition
of Gillette and its subsidiaries and other factors. See "Comparative Per Share
Prices and Dividends -- Post-Merger Dividend Policy."

                                 THE COMPANIES
 
THE GILLETTE COMPANY
 
     Founded in 1901, Gillette is the world leader in male grooming products, a
category that includes blades and razors, shaving preparations and electric
shavers. Gillette also holds the number one position worldwide in selected
female grooming products, such as wet shaving products and hair epilation
devices. In addition, Gillette is the world's top seller of writing instruments
and correction products and the world leader in toothbrushes and oral care
appliances. Gillette products are distributed through wholesalers, retailers and
agents in over 200 countries and territories, with sales in fiscal 1995 of
approximately $6.8 billion.
 
DURACELL INTERNATIONAL INC.
 
     Duracell manufactures and markets, primarily under the DURACELL(R) brand,
high performance alkaline batteries, primary lithium batteries and other battery
types. Duracell also markets rechargeable nickel metal hydride batteries and a
lighting products line. Duracell maintains a leading position in North American
and European consumer battery markets with its "copper and black" DURACELL brand
alkaline batteries. Alkaline batteries accounted for approximately 83% of
Duracell's sales during fiscal 1996. Duracell's batteries are sold worldwide
through consumer channels, to industrial users and to manufacturers of
battery-powered consumer, industrial, medical and military equipment.
 
                       COMPARATIVE RIGHTS OF STOCKHOLDERS
 
     The following is a summary of the material differences between the rights
of holders of Duracell Common Stock and holders of Gillette Common Stock.
Because both Duracell and Gillette are organized under the laws of the State of
Delaware, such differences arise from differences between various provisions of
the Restated Certificate of Incorporation, as amended (the "Duracell
Certificate"), and By-Laws of Duracell and the Certificate of Incorporation (the
"Gillette Certificate") and By-Laws of Gillette. This summary does not purport
to be complete and is qualified in its entirety by reference to the relevant
provisions of Delaware law and to the Gillette Certificate and By-Laws of
Gillette. The Gillette Certificate and By-Laws are Exhibits to the Registration
Statement of which this Joint Proxy Statement/Prospectus is a part and are
incorporated herein by reference.
 
SPECIAL MEETING OF STOCKHOLDERS
 
     Delaware law provides that special meetings of stockholders may be called
only by the directors or by any other person as may be authorized by the
corporation's certificate of incorporation or by-laws. Duracell's By-Laws
provide that special meetings may be called by the President for any purpose and
must be called by the President or Secretary if directed by the Board of
Directors or requested in writing by stockholders owning no less than 50% of the
outstanding capital stock of Duracell. Gillette's By-Laws provide that special
meetings may be called by means of a writing filed with the secretary signed by
the chief executive officer or by a majority of the directors.
 
ADVANCE NOTICE OF STOCKHOLDER PROPOSALS AND BOARD NOMINATIONS
 
     The respective By-Laws of Duracell and Gillette provide that a stockholder
must give advance written notice to the respective company if the stockholder
intends to bring any business before a meeting of stockholders or to make
nominations for the board of directors. Duracell's advance notice provisions
require stockholders to give such notice not less than 60 days nor more than 90
days prior to the meeting at which the business would be acted upon. The advance
notice provisions for Gillette require that the notice be received not less than
60 days prior to the meeting.
 
                                       69
<PAGE>   79
 
QUORUMS
 
     Delaware law provides that the number of shares necessary to constitute a
quorum at a meeting of stockholders may be fixed by the certificate of
incorporation or the by-laws of a corporation, but in no event shall such number
consist of less than one third of the shares entitled to vote at the meeting.
Delaware also provides that a majority of the total number of directors shall
constitute a quorum for the transaction of business at a meeting of directors
unless the certificate of incorporation or the by-laws require a greater number;
provided that unless the certificate of incorporation otherwise provides, the
by-laws may provide that a number less than a majority shall constitute a quorum
which in no case shall be less than one-third of the total number of directors
(with certain exceptions not applicable to Duracell or Gillette). The Duracell
By-Laws provide that a quorum consists of a majority of the corporation's issued
and outstanding shares of capital stock for a stockholders' meeting and one
third of the total number of directors for the transaction of business at a
meeting of directors. The Gillette By-Laws provide that one third of the
outstanding shares entitled to vote shall constitute a quorum for a
stockholders' meeting, while a majority of the total number of directors is a
quorum for the transaction of business at a meeting of directors.
 
CLASSIFICATION OF THE BOARD OF DIRECTORS
 
     Delaware law permits (but does not require) classification of a
corporation's board of directors into one, two or three classes. The Duracell
Certificate and By-Laws do not provide for such classification, while the
Gillette Certificate and By-Laws provide for three classes, designated Class I,
Class II and Class III. Each class consists, as nearly as is possible, of one
third of the total number of directors on the board. Generally, the term of
office of Duracell directors is one year and the term of office of Gillette
directors is three years.
 
REMOVAL OF DIRECTORS
 
     Under Delaware law, although stockholders may generally remove directors
with or without cause by a majority vote, stockholders may remove members of
classified boards only for cause unless the certificate of incorporation
provides otherwise. The Duracell By-Laws provide that a director may be removed,
with or without cause, by the holders of a majority of the issued and
outstanding shares then entitled to vote at an election of directors. The
Gillette By-Laws follow Delaware law and allow removal of directors from
Gillette's classified board by a vote of the shareholders holding a majority of
the votes entitled to be cast only for cause.
 
VACANCIES ON THE BOARD OF DIRECTORS
 
     Under Delaware law, unless otherwise provided in the charter or by-laws,
vacancies on the board of directors and newly created directorships resulting
from any increase in the authorized number of directors may be filled by the
remaining directors. The Duracell By-Laws provide that any vacancy on the Board
of Directors, however created, may be filled by a majority of the directors then
in office, even if less than a quorum, or by a sole remaining director, or by
the holders of a majority of shares entitled to vote thereon, while the Gillette
Certificate and By-Laws provide that a vacancy on the Board of Directors may be
filled only by a majority of the directors then in office or by a sole remaining
director.
 
INDEMNIFICATION OF DIRECTORS, OFFICERS AND OTHERS
 
     Delaware law generally permits indemnification of directors, officers,
employees and agents for expenses, judgments, fines and amounts paid in
settlement of claims incurred by them by reason of their position with the
corporation, if such persons have acted in good faith and with the reasonable
belief that their conduct was in the best interest of the corporation. However,
Delaware law does not permit a corporation to indemnify persons against
judgments, fines and amounts paid in settlement in actions brought by or in the
right of the corporation. Delaware law does permit indemnification of expenses
of such actions, unless the persons have been adjudged to be liable to the
corporation, in which case indemnification is available only if approved by the
Delaware Court of Chancery or the court in which such action or suit was
brought. Duracell's By-Laws provide that Duracell shall indemnify current or
former directors and officers, and may at the discretion of the Board of
Directors indemnify its current and former employees, in connection with
proceedings brought
 
                                       70
<PAGE>   80
 
against such persons by reason of their position with Duracell to the fullest
extent permitted by Delaware law. The Gillette By-Laws provide that Gillette
shall indemnify current or former directors, officers, employees or agents of
the corporation in connection with proceedings brought against such persons by
reason of their position with Gillette to the fullest extent permitted by
Delaware law.
 
AMENDMENTS TO CHARTER
 
     Under Delaware law, charter amendments require the approval of the
directors and the vote of the holders of a majority of the outstanding stock and
a majority of each class of stock outstanding and entitled to vote thereon as a
class, unless the certificate of incorporation requires a greater proportion.
The Duracell Certificate does not require a greater proportion. The Gillette
Certificate requires the affirmative vote of 75% of the voting power of the
outstanding shares, voting together as a single class, to amend, repeal or adopt
any provision inconsistent with Article 9 of the Gillette Certificate, which
includes the board classifications and the procedure for filling vacancies on
the board; other amendments require the affirmative vote of a majority of the
voting power of the outstanding shares, voting together as a single class. In
addition, Delaware law requires a class vote when, among other things, an
amendment will adversely affect the powers, preferences or special rights of a
class of stock.
 
ACQUISITIONS OF STOCK
 
     The Gillette By-Laws contain restrictions on Gillette's acquisition of
stock that have no counterpart in the Duracell Certificate or By-Laws. These
restrictions state that Gillette shall not acquire any of its voting equity
securities at a price above the average market price of such securities from any
person who is the beneficial owner of more than three percent of the
corporation's voting equity securities and has been such for less than two
years, unless such acquisition is pursuant to the same offer and terms as made
to all holders of securities of such class and to all holders of any other class
from or into which such securities may be converted.
 
     This restriction does not apply to any acquisition that has been approved
by a vote of a majority of the shares entitled to vote, excluding those owned by
any such beneficial owner any of whose shares are proposed to be acquired
pursuant to that vote.
 
     In addition, this provision does not restrict Gillette from: (1)
reacquiring shares in the open market in transactions in which all stockholders
have an equal chance to sell their shares, and in number of shares that do not
exceed in any one day the daily average trading volume for the preceding three
months; (2) offering to acquire at market prices all shares of any stockholder
owning less than 100 shares of common stock; or (3) reacquiring shares pursuant
to the terms of a stock option plan that has been approved by a vote of a
majority of the common shares.

                   STOCK OWNERSHIP OF MANAGEMENT AND CERTAIN
                         BENEFICIAL OWNERS OF DURACELL
 
     The following table sets forth certain information regarding the beneficial

of all options exercisable on, or within 60 days of, such date, by (i) each
director, (ii) the Chief Executive Officer and each of the other four most
highly compensated executive officers of Duracell, (iii) all executive officers

                          GILLETTE CONFIDENTIAL VOTING
 
     The Board of Directors of Gillette has determined that the confidential
voting policy employed for the last several years will apply to the Gillette
Special Meeting. Gillette's policy requires that proxies and ballots be kept
confidential from officers, directors and employees of Gillette and from third
parties. Certain outside agents, such as those serving as proxy solicitors, who
have agreed to comply with this policy, but not Gillette employees, directors or
officers, may be permitted access to proxies and conducting ballots to
facilitate their participation in soliciting proxies and conducting the meeting.
The policy will not prevent Gillette officers, directors or other employees or
representatives from determining which stockholders have not voted so that they
can be urged to vote. The policy will not apply in the event of a proxy contest
or other solicitation based on an opposition proxy statement.
 
                                 OTHER MATTERS
 
     If sufficient votes in favor of the Duracell Merger Proposal or the
Gillette Share Proposal are not received by the time scheduled for the Duracell
Special Meeting or the Gillette Special Meeting, respectively, the persons named
as proxies may propose one or more adjournments of the Duracell Special Meeting
or the Gillette Special Meeting, as the case may be, for a period or periods of
not more than 30 days in the aggregate for each Special Meeting to permit
further solicitation of proxies. The persons named as proxies will vote in favor
of such adjournment those proxies which authorize them to vote in favor of the
Duracell Merger Proposal or the Gillette Share Proposal, as the case may be.
They will vote against any such adjournment those proxies which direct them to
vote against the Duracell Merger Proposal or the Gillette Share Proposal, as the
case may be. Any such adjournment will require the affirmative vote of a
majority of the votes cast on the question in person or by proxy at the session
of the Duracell Special Meeting or the Gillette Special Meeting to be adjourned.
The costs of any such additional solicitation and of any adjourned session will
be borne by Duracell with respect to the Duracell Special Meeting and by
Gillette with respect to the Gillette Special Meeting.
 
     It is not expected that any matters other than those described in this
Joint Proxy Statement/Prospectus will be brought before the Duracell Special
Meeting or the Gillette Special Meeting. If any other matters are presented,
however, it is the intention of the persons named in the Duracell proxy and
Gillette proxy to vote the proxy in accordance with the discretion of the
persons named in such proxy.
 
                                 LEGAL MATTERS
 
     Certain legal matters with respect to the validity of the securities
offered hereby and the Merger will be passed upon for Gillette by Joseph E.
Mullaney, Vice Chairman of the Board of Gillette. Mr. Mullaney beneficially owns
approximately 346,274 shares of Gillette Common Stock. Certain other legal
matters in connection with the Merger will be passed upon by Ropes & Gray,
Boston, Massachusetts. A member of Ropes & Gray beneficially owns approximately
2,700 shares of Gillette Common Stock. Certain legal matters in connection with
the Merger will be passed upon for Duracell by Simpson Thacher & Bartlett (a
partnership which includes professional corporations), New York, New York.

VI, at the offices of Ropes & Gray, One International Place, Boston,
Massachusetts, unless another date, time or place is agreed to in writing by the

satisfaction or waiver of the conditions set forth in Article VI, the parties
hereto shall cause the Merger to be consummated by filing a certificate of
merger as contemplated by the DGCL (the "CERTIFICATE OF MERGER"), 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 1.3  Effect of the Merger.  At the Effective Time, the effect of
the Merger shall be as provided in this Agreement, the Certificate of Merger and
the applicable provisions of the DGCL. Without limiting the generality of the
foregoing, and subject thereto, at the Effective Time, all the property, rights,
privileges, powers and franchises of the Company and Merger Sub shall vest in
the Surviving Corporation, and all debts, liabilities and duties of the Company
and Merger Sub shall become the debts, liabilities and duties of the Surviving
Corporation.
 
     SECTION 1.4  Certificate of Incorporation, By-Laws.
 
     (a) Certificate of Incorporation.  At the Effective Time the Certificate of
Incorporation of the Company, as in effect immediately prior to the Effective
Time, shall be the Certificate of Incorporation of the Surviving Corporation
until thereafter amended in accordance with the DGCL and such Certificate of
Incorporation.
 
     (b) By-Laws.  The By-Laws of the Company, as in effect immediately prior to
the Effective Time, shall be the By-Laws of the Surviving Corporation until
thereafter amended in accordance with the DGCL, the Certificate of Incorporation
of the Surviving Corporation and such By-Laws; provided, however, that the Board
of Directors of the Surviving Corporation shall consist of the same number of
directors as the number of directors of Merger Sub at the Effective Time.
 
     SECTION 1.5  Directors and Officers.  The directors of Merger Sub
immediately prior to the Effective Time shall be the initial directors of the
Surviving Corporation, each to hold office in accordance with the Certificate of
Incorporation and By-Laws of the Surviving Corporation, and the officers of the
Company immediately prior to the Effective Time shall be the initial officers of
the Surviving Corporation, in each case until their respective successors are
duly elected or appointed and qualified.
 
     SECTION 1.6  Effect on Capital Stock.  At the Effective Time, by virtue of
the Merger and without any action on the part of the Parent, Merger Sub, the
Company or the holders of any of the following securities:
 
     (a) Conversion of Securities.  Each Share issued and outstanding
immediately prior to the Effective Time (excluding any Shares to be canceled
pursuant to Section 1.6(b)) shall be converted, subject to Section 1.6(f), into
the right to receive 0.904 shares (the "EXCHANGE RATIO") of validly issued,
fully paid and nonassessable shares ("PARENT SHARES") of the Common Stock, $1.00
par value, of Parent ("PARENT COMMON STOCK") (together with the preferred stock
purchase right attached thereto).
 
     (b) Cancellation.  Each Share held in the treasury of the Company and each
Share owned by Parent, Merger Sub or any direct or indirect wholly owned
subsidiary of the Company or Parent immediately prior to the Effective Time
shall, by virtue of the Merger and without any action on the part of the holder
thereof, cease to be outstanding, be canceled and retired without payment of any
consideration therefor and cease to exist.
 
     (c) Stock Options.
 
          (i) At the Effective Time, each outstanding option to purchase Company
     Common Stock (a "STOCK OPTION") granted under (A) the Duracell Shares Plan,
     or (B) the Company's Stock Option Plan for Key Employees (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 to the nearest whole number) of
     Parent Shares as the holder of such Stock Option
 
                                       A-2
<PAGE>   90
 
     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 equal to (x) the aggregate exercise price for Company
     Common Stock otherwise purchasable pursuant to such Stock Option divided by
     (y) the number of Parent Shares deemed purchasable pursuant to such Stock
     Option.
 
          (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
     antidilution provisions).
 
          (iii) Parent shall take all corporate action necessary to reserve for
     issuance a sufficient number of Parent Shares for delivery pursuant to the
     terms set forth in this Section 1.6(c).
 
          (iv) Subject to any applicable limitations under the Securities Act of
     1933, as amended, and the rules and regulations thereunder (the "SECURITIES
     ACT"), Parent shall either (A) file a Registration Statement on Form S-8
     (or any successor form), effective as of the Effective Time, with respect
     to the shares of Parent Common Stock issuable upon exercise of the Stock
     Options, or (B) file any necessary amendments to the Company's
     previously-filed Registration Statement(s) on Form S-8 in order that the
     Parent will be deemed a "successor registrant" thereunder, and, in either
     event the Parent shall use all reasonable efforts to maintain the
     effectiveness of such registration statement(s) (and maintain the current
     status of the prospectus or prospectuses relating thereto) for so long as
     such options shall remain outstanding.
 
     (d) Capital Stock of Merger Sub.  Each share of common stock, $.01 par
value, of Merger Sub issued and outstanding immediately prior to the Effective
Time shall be converted into and exchanged for one validly issued, fully paid
and nonassessable share of common stock, $.01 par value, of the Surviving
Corporation.
 
     (e) Adjustments to Exchange Ratio.  The Exchange Ratio shall be adjusted to
reflect fully the effect of any stock split, reverse split, stock 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.
 
     (f) Fractional Shares.  No certificates or scrip representing less than one
Parent Share shall be issued upon the surrender for exchange of a certificate or
certificates which immediately prior to the Effective Time represented
outstanding Shares (the "CERTIFICATES"). In lieu of any such fractional share,
each holder of Shares who would otherwise have been entitled to a fraction of a
Parent Share upon surrender of Certificates for exchange shall be paid upon such
surrender cash equal to the product of (i) such fraction, multiplied by (ii) the
closing price per share on the New York Stock Exchange ("NYSE") of Parent Common
Stock as reported in the Eastern Edition of the Wall Street Journal on the
trading date prior to the date on which the Effective Time occurs.
 
     SECTION 1.7  Exchange of Certificates.
 
     (a) Exchange Agent.  At or prior to the Effective Time Parent shall supply,
or shall cause to be supplied, to or for the account of The First National Bank
of Boston, or such other bank or trust company as shall be 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 1.7, through the
Exchange Agent, certificates evidencing the Parent Shares issuable pursuant to
Section 1.6 in exchange for outstanding Shares. Parent agrees to make available
to the Exchange Agent from time to time as needed, cash sufficient to pay cash
in lieu of fractional shares and any dividends and distributions.
 
     (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 Certificates (i) a letter of transmittal (which
 
                                       A-3
<PAGE>   91
 
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 Parent Shares. Upon
surrender of a Certificate for cancellation to the Exchange Agent 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 Parent Shares 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 to which such
holder is entitled pursuant to Section 1.7(c), and (C) cash in respect of
fractional shares as provided in Section 1.6(f) (the Parent Shares, dividends,
distributions and cash 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 Shares, dividends and
distributions 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 1.7(b) and by evidence that any
applicable stock transfer taxes have been paid. Until so surrendered, each
outstanding Certificate that, prior to the Effective Time, represented Shares of
Company Common Stock will be deemed from and after the Effective Time, for all
corporate purposes, other than the payment of dividends and subject to Section
1.6(f), to evidence the ownership of the number of full Parent Shares into which
such shares of Company Common Stock shall have been so converted.
 
     (c) Distributions With Respect to Unexchanged Parent Shares.  No dividends
or other distributions declared or made after the Effective Time with respect to
Parent Shares with a record date after the Effective Time shall be paid to the
holder of any unsurrendered Certificate with respect to the Parent Shares they
are entitled to receive until the holder of such Certificate shall surrender
such Certificate. Subject to applicable law and the provisions of Section 1.7(e)
below, following surrender of any such Certificate, there shall be paid to the
record holder of the certificates representing whole Parent Shares 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 Parent Shares.
 
     (d) Transfers of Ownership.  If any certificate for Parent Shares 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 to 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 Parent Shares in any
name other than that of the registered holder of the certificate surrendered, or
have 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.  At any time following one year after the Effective Time,
Parent shall be entitled to require the Exchange Agent to deliver to Parent any
Merger Consideration which had been made available to the Exchange Agent by or
on behalf of Parent and which has not been disbursed to holders of Certificates,
and thereafter such holders shall be entitled to look to Parent only as general
creditors thereof with respect to the Merger Consideration payable upon due
surrender of their Certificates. Notwithstanding the foregoing, neither Parent,
Merger Sub nor the Company shall be liable to any holder of Company Common Stock
for any Merger Consideration 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 Company Common Stock 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.
 
                                       A-4
<PAGE>   92
 
     SECTION 1.8  Stock Transfer Books.  At the Effective Time, the stock
transfer books of the Company shall be closed, and there shall be no further
registration of transfers of Company Common Stock thereafter on the records of
the Company.
 
     SECTION 1.9  No Further Ownership Rights in Company Common Stock.  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 Corporation of
Shares which were outstanding immediately prior to the Effective Time. If, after
the Effective Time, Certificates are presented to the Surviving Corporation for
any reason, they shall be canceled and exchanged as provided in this Article I.
 
     SECTION 1.10  Lost, Stolen or Destroyed Certificates.  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 and delivery of 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, such Parent Shares as may be
required pursuant to Section 1.6.
 
     SECTION 1.11  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 of the Code and (ii) qualify for accounting treatment as
a pooling of interests. The parties hereto hereby adopt this Agreement as a
"plan of reorganization" within the meaning of Sections 1.368-2(g) and
1.368-3(a) of the United States Treasury Regulations.
 
     SECTION 1.12  Taking of Necessary Action; Further Action.  Each of Parent,
Merger Sub and the Company will take all such reasonable and lawful action as
may be necessary or appropriate in order to effectuate the Merger in accordance
with this Agreement as promptly as possible. If, at any time after the Effective
Time, any such further action is necessary or desirable to carry out the
purposes of this Agreement and to vest the Surviving Corporation with full
right, title and possession to all assets, property, rights, privileges, powers
and franchises of the Company and Merger Sub, the officers and directors of the
Company and Merger Sub immediately prior to the Effective Time are fully
authorized in the name of their respective corporations or otherwise to take,
and will take, all such lawful and necessary action.
 
     SECTION 1.13  Material Adverse Effect.  When used in connection with the
Company or any of its subsidiaries, or Parent or any of its subsidiaries, as the
case may be, the term "MATERIAL ADVERSE EFFECT" means any change, effect or
circumstance that, individually or when taken together with all other such
changes, effects or circumstances that have occurred prior to the date of
determination of the occurrence of the Material Adverse Effect, (a) is or is
reasonably likely to be materially adverse to the business, assets (including
intangible assets), financial condition or results of operations of the Company
and its subsidiaries or Parent and its subsidiaries, as the case may be, in each
case taken as a whole, or (b) does or is reasonably likely to delay or prevent
the consummation of the transactions contemplated hereby.
 
                                   ARTICLE II

                 REPRESENTATIONS AND WARRANTIES OF THE COMPANY
 
     The Company hereby represents and warrants to Parent and Merger Sub as
follows:
 
     SECTION 2.1  Organization and Qualification; Subsidiaries.  Each of the
Company and each of its significant subsidiaries (as defined in Section 8.3 or
listed in Section 2.1 of the Company Disclosure Schedule (as defined below)) is
a corporation duly organized, validly existing and in good standing under the
laws of the jurisdiction of its incorporation and has the requisite corporate
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, operate or lease and to carry on its business as it is now
being conducted, except where the failure to be so organized, existing and in
good standing or to have such power, authority and Approvals does not constitute
a Material Adverse
 
                                       A-5
<PAGE>   93
 
Effect. Each of the Company and each of its significant subsidiaries is duly
qualified or licensed as a foreign corporation 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 do not constitute a Material
Adverse Effect. Substantially all of the business and operations of the Company
and its subsidiaries are conducted through, and substantially all of the
properties and assets of the Company and its subsidiaries are owned by, the
Company and its significant subsidiaries.
 
     SECTION 2.2  Certificate of Incorporation and By-Laws.  The Company has
heretofore furnished to Parent a complete and correct copy of its Certificate of
Incorporation and By-Laws as most recently restated and subsequently amended to
date. Such Certificate of Incorporation and By-Laws are in full force and
effect. The Company is not in violation of any of the provisions of its
Certificate of Incorporation or By-Laws.
 
     SECTION 2.3  Capitalization.  The authorized capital stock of the Company
consists of (1) 150,000,000 shares of Company Common Stock and (ii) 100,000,000
shares of preferred stock, $.01 par value per share, none of which is issued and
outstanding and none of which is held in treasury. As of August 31, 1996, (i)
119,376,762 shares of Company Common Stock were issued and outstanding, all of
which are validly issued, fully paid and nonassessable, and 1,000,000 shares of
Company Common Stock were held in treasury, (ii) no shares of Company Common
Stock were held by subsidiaries of the Company, and (iii) 6,783,421 shares of
Company Common Stock were reserved for future issuance pursuant to outstanding
stock options granted under the Company Stock Option Plans. No material change
in such capitalization has occurred between August 31, 1996 and the date hereof.
Except as set forth in this Section 2.3, Section 2.3 or Section 2.11 of the
written disclosure schedule delivered on or prior to the date hereof by the
Company to Parent that is arranged in paragraphs corresponding to the numbered
and lettered paragraphs contained in this Article II (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
capital stock of the Company or any of its significant subsidiaries or
obligating the Company or any of its subsidiaries to issue or sell any shares of
capital stock of, or other equity interests in, the Company or any of its
significant subsidiaries. None of the options, warrants, rights, agreements,
arrangements or commitments identified in Section 2.3 or Section 2.11 of the
Company Disclosure Schedule provide that, absent action by the Board of
Directors or a committee thereof, upon exercise or conversion the holder thereof
shall receive cash, and no such action of the Board of Directors or a committee
thereof has been taken. 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 issuable, shall be duly authorized,
validly issued, fully paid and nonassessable. Except as disclosed in Section 2.3
of the Company Disclosure Schedule, there are no obligations, contingent or
otherwise, of the Company or any of its significant subsidiaries to repurchase,
redeem or otherwise acquire any shares of Company Common Stock or the capital
stock of any significant subsidiary or to provide funds to or make any
investment (in the form of a loan, capital contribution, guaranty or otherwise)
in any such subsidiary or any other entity. Except as set forth in Section 2.3
of the Company Disclosure Schedule, all of the outstanding shares of capital
stock of each of the Company's significant subsidiaries is duly authorized,
validly issued, fully paid and nonassessable, and all such shares (other than
directors' qualifying shares) are owned by the Company or another subsidiary of
the Company free and clear of all security interests, liens, claims, pledges,
agreements, limitations in the Company's voting rights, charges or other
encumbrances of any nature whatsoever (collectively, "LIENS").
 
     SECTION 2.4  Authority Relative to this Agreement.
 
     (a) The Company has all necessary corporate power and authority to execute
and deliver this Agreement and 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 adoption of this Agreement by the
holders of at least a majority of the outstanding shares of Company Common Stock
entitled to vote in accordance with the
 
                                       A-6
<PAGE>   94
 
DGCL and the Company's Certificate of Incorporation and By-Laws). 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.
 
     (b) The Board of Directors of the Company has duly and validly approved and
taken all corporate action required to be taken by the Board of Directors for
the consummation of the transactions contemplated by this Agreement and the
Stockholders Agreement, including, but not limited to, all actions necessary to
render the provisions of Section 203 of the DGCL inapplicable to this Agreement,
the Merger and the Stockholders Agreement. 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 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 Merger.
 
     SECTION 2.5  No Conflict; Required Filings and Consents.
 
     (a) The exhibit index to the Company's most recently filed Annual Report on
Form 10-K, as supplemented by Section 2.5(a) of the Company Disclosure Schedule,

defaults or failures to be in full force and effect that do not constitute a
Material Adverse Effect.
 
     (c) Except as set forth in Section 2.5(c) 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 and the consummation 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 of
its significant subsidiaries or by which its or any of their respective

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 of its significant subsidiaries'
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, or
result in the creation of a Lien on any of the properties or assets of the
Company or any of its significant subsidiaries pursuant to, any note, bond,
mortgage, indenture, contract, agreement, lease, license, permit, franchise or
other instrument or obligation to which the Company or any of its significant
subsidiaries is a party or by which the Company or any of its significant
subsidiaries or its or any of their respective properties is bound or affected,
except in the case of clauses (ii) and (iii) for any such conflicts, violations,
breaches, defaults or other occurrences that do not constitute a Material
Adverse Effect.
 
     (d) The execution and delivery of this Agreement by the Company does not,
and the performance of this Agreement by the Company will not, require any
consent, approval, authorization or permit of, or filing with or notification
to, any domestic or foreign governmental or regulatory authority except (i) for
applicable requirements, if any, of the Securities Act, the Securities Exchange

foreign jurisdictions and the filing and recordation of appropriate merger or
other documents as required by the DGCL, and (ii) where the failure to obtain
such consents, approvals, authorizations or permits, and to make such filings or
notifications, would not prevent or delay consummation of the Merger, and
otherwise prevent or delay the Company from performing its obligations under
this Agreement, and do not constitute a Material Adverse Effect.
 
     SECTION 2.6  Compliance, Permits.
 
     (a) Except as disclosed in Section 2.6(a) of the Company Disclosure
Schedule, neither the Company nor any of its significant subsidiaries is in
conflict with, or in default or violation of, (i) any Law applicable to the
Company or any of its significant subsidiaries or by which its or any of their
respective properties is bound or affected or (ii) any note, bond, mortgage,
indenture, contract, agreement, lease, license, permit, franchise or other
instrument or obligation to which the Company or any of its significant
subsidiaries is a party or by which the Company or any of its subsidiaries or
its or any of their respective properties is bound or affected, except, in each
case, for any such conflicts, defaults or violations which do not constitute a
Material Adverse Effect.
 
     (b) Except as disclosed in Section 2.6(b) of the Company Disclosure
Schedule, the Company and its significant subsidiaries hold all permits,
licenses, easements, variances, exemptions, consents, certificates, orders and
approvals from governmental authorities which are material to the operation of
the business of the Company and its subsidiaries taken as a whole as it is now
being conducted (collectively, the "COMPANY PERMITS"). The Company and its
significant subsidiaries are in compliance with the terms of the Company
Permits, except where the failure to so comply does not constitute a Material
Adverse Effect.

                                      A-10
<PAGE>   98

effectiveness or the existence of such default or event of default does not
constitute a Material Adverse Effect.

all Taxes due in connection with or with respect to the periods or transactions
covered by such Tax Returns and have paid all other Taxes as are due, except
such as are being contested in good faith by appropriate proceedings (to the
extent that any such proceedings are required) and with respect to which the
Company is maintaining adequate reserves, and (iii) there are no other Taxes
that would be due if asserted by a taxing authority, except with respect to

accounting principles applied on a consistent basis with the 1995 Company
Balance Sheet, and the accrual and reserves for Taxes (including deferred taxes)

the 1995 Company Balance Sheet.

liability, or otherwise form the basis of any claim, action, suit or proceeding,
against the Company or any of its subsidiaries based on or resulting from the
manufacture, processing, distribution, use, treatment, storage, disposal,
transport or handling, or the emission, discharge or release into the

misappropriation of any of the Company Intellectual Property Rights by any third
party, including any employee or former employee of the Company or any of its

     Parent and Merger Sub hereby jointly and severally represent and warrant to
the Company as follows:
 
     SECTION 3.1  Organization and Qualification; Subsidiaries.  Each of Parent
and each of its significant subsidiaries is a corporation duly organized,
validly existing and in good standing under the laws of the jurisdiction of its
incorporation and has the requisite corporate power and authority and is in
possession of all Approvals necessary to own, lease and operate the properties
it purports to own, operate or lease and to carry on its business as it is now
being conducted, except where the failure to be so organized, existing and in
good standing or to have such power, authority and Approvals does not constitute
a Material Adverse Effect. Each of Parent and each of its significant
subsidiaries is duly qualified or licensed as a foreign corporation 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 do not constitute a
Material Adverse Effect. Substantially all of the business and operations of
Parent and its subsidiaries are conducted through,
 
                                      A-13
<PAGE>   101
 
and substantially all of the properties and assets of Parent and its
subsidiaries are owned by, Parent and its significant subsidiaries.
 
     SECTION 3.2  Charter and By-Laws.  Parent has heretofore furnished to the
Company a complete and correct copy of its Certificate of Incorporation and
By-Laws, as most recently restated and subsequently amended to date. Such
Certificate of Incorporation and By-Laws are in full force and effect. Parent is
not in violation of any of the provisions of its Certificate of Incorporation or
By-Laws.
 
     SECTION 3.3  Capitalization.  As of August 31, 1996, the authorized capital
stock of Parent consisted of (i) 1,160,000,000 shares of Parent Common Stock of
which 445,784,108 shares were issued and outstanding, all of which are validly
issued, fully paid and nonassessable, 115,398,992 shares were held in treasury,
and 23,925,438 shares were reserved for future issuance under Parent's stock
option and employee stock purchase plans, (ii) 55,723,013.5 preferred stock
purchase rights (the "Rights") were issued and outstanding and attached to each
outstanding share of Parent Common Stock and (iii) 5,000,000 shares of preferred
stock, without par value per share, of which 159,057.2537 shares of 8.0%
Cumulative Series C ESOP Convertible Preferred were issued and outstanding, none
of which were held in treasury, and 400,000 shares of Series A Junior
Participating Preferred Stock were reserved for issuance upon exercise of the
Rights. No material change in such capitalization has occurred between August

Section 3.3 of the written disclosure schedule delivered on or prior to the date
hereof by Parent to the Company that is arranged in paragraphs corresponding to
the numbered and lettered paragraphs contained in this Article III (the "Parent
Disclosure Schedule") or as set forth in the Parent SEC Reports, there are no
options, warrants or other rights, agreements, arrangements or commitments of
any character outstanding on the date hereof obligating Parent to issue or sell
any shares of capital stock of, or other equity interests in, Parent, other than
options or similar rights outstanding on the date hereof to purchase an
aggregate of 15,508,457 shares of Parent Common Stock.
 
     SECTION 3.4  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 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
(other than the approval of the issuance of Parent Common Stock in the Merger by
the affirmative vote of the holders of a majority of the voting power of the
shares of the Parent Common Stock present in person, or represented by proxy,
and entitled to vote thereon at the meeting of holders of Parent Common Stock to
be called therefor, provided that the shares so present or represented
constitute a majority of the outstanding shares of Parent Common Stock) are
necessary to authorize this Agreement or to consummate the transactions
contemplated thereby. 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 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,

(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

respective dates thereof and the consolidated results of its operations and cash
flows and stockholders equity 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.
 
     SECTION 3.8  Absence of Certain Changes or Events.  Except as set forth in

proceedings or investigations pending or, to the knowledge of the Parent,

     SECTION 3.11  Labor Matters.  Except as set forth in Section 3.11 of the
Parent Disclosure Schedule: (i) there are no claims or proceedings pending or,
to the knowledge of Parent or any of its subsidiaries, threatened, between

Parent nor any of its subsidiaries has any knowledge of any strikes, slowdowns,
work stoppages, lockouts, or threats thereof, by or with respect to any

     SECTION 3.12  Registration Statement; Joint Proxy
Statement/Prospectus.  Subject to the accuracy of the representations of the
Company in Section 2.13, the registration statement (the "REGISTRATION
STATEMENT") pursuant to which the Parent Common Stock to be issued in the Merger
will be registered with the SEC 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 necessary in order to make the statements included
therein not misleading. The information supplied by Parent for inclusion or
incorporation by reference in the Joint Proxy Statement/Prospectus will not, on
the date the Joint Proxy Statement/Prospectus is first mailed to stockholders,
at the time of the Stockholders Meetings and at the Effective Time, 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, or will
omit to state any material fact necessary in order to make the statements
therein not false or misleading; or omit to state any material fact necessary to
correct any statement in any earlier communication with respect to the
solicitation of proxies for the Stockholders Meetings which has become false or
misleading. If at any time prior to the Effective Time any event relating to
Parent, Merger Sub or any of their respective affiliates, officers or directors
should be discovered by Parent or Merger Sub which should be set forth in an
amendment to the Registration Statement or a supplement to the Joint Proxy
Statement/Prospectus, Parent or Merger Sub will promptly inform the Company.
Notwithstanding the foregoing, Parent and Merger Sub make no representation or
warranty with respect to any information supplied by the Company which is
contained or incorporated by reference in any of the foregoing documents.
 
     SECTION 3.13  [Intentionally Omitted]
 
     SECTION 3.14  Title to Property.  Except as disclosed in Section 3.14 of
the Parent Disclosure Schedule, Parent and each of its subsidiaries have good
and defensible title to all of their properties and assets, free and clear of
all liens, charges and encumbrances, except liens for taxes not yet due and
payable and such liens or other imperfections of title, which do not constitute
a Material Adverse Effect; and, to Parent's knowledge, all leases pursuant to
which Parent or any of its subsidiaries lease from others material amounts of
real or personal property are in good standing, valid and effective in
accordance with their respective terms, and there is not, to the knowledge of
Parent, under any of such leases, any existing material default or event of
default (or event which with notice or lapse of time, or both, would constitute
a material default) except where the lack of such good standing, validity and
effectiveness or the existence of such default or event of default does not
constitute a Material Adverse Effect.
 
     SECTION 3.15  Taxes.  Other than as disclosed in Section 3.15 of the Parent
Disclosure Schedule, (i) Parent and its subsidiaries have filed all United
States federal income Tax Returns and all other material Tax Returns required to
be filed by them, (ii) Parent and its subsidiaries have paid and discharged all
Taxes due in connection with or with respect to the periods or transactions
covered by such Tax Returns and have paid all other Taxes as are due, except
such as are being contested in good faith by appropriate proceedings (to the
extent that any such proceedings are required) and with respect to which Parent
is maintaining adequate reserves, and (iii) there are no other Taxes that would
be due if asserted by a taxing authority, except with respect to which Parent is
maintaining reserves to the extent currently required unless the failure to do
so does not constitute a Material Adverse Effect. Except as does not involve or
would not result in liability to Parent that constitutes a Material Adverse
Effect: (i) there are no tax liens on any assets of Parent or any subsidiary
thereof; and (ii) neither Parent nor any of its subsidiaries has granted any
waiver of any statute of limitations with respect to, or any extension of a
period for the assessment of, any Tax. The accruals and reserves for Taxes
(including deferred taxes) reflected in the balance sheet of Parent as at June
30, 1996 included in the Parent's Quarterly Report on Form 10-Q for the quarter
ended June 30, 1996 are in all material respects adequate to cover all Taxes
required to be accrued through the date thereof (including interest and
penalties,
 
                                      A-17
<PAGE>   105
 
if any, thereon and Taxes being contested) in accordance with generally accepted
accounting principles applied on a consistent basis with the Parent Balance
Sheet, and the accruals and reserves for Taxes (including deferred taxes)
reflected in the books and records of Parent as at the last day of Parent's most
recently completed fiscal month end are in all material respects adequate to
cover all Taxes required to be accrued through such date (including interest and
penalties, if any, thereon and Taxes being contested) in accordance with
generally accepted accounting principles applied on a consistent basis with the
Parent Balance Sheet.
 
     SECTION 3.16  Environmental Matters.  Except as set forth in Section 3.16
of the Parent Disclosure Schedule, and except in all cases as, in the aggregate,
does not constitute a Material Adverse Effect, Parent and each of its
subsidiaries: (i) have obtained all Approvals which are required to be obtained
under all applicable Environmental Laws by Parent or its subsidiaries (or their
respective agents); (ii) are in compliance with all terms and conditions of such
required permits, licenses and authorization, and also are in compliance with
all other limitations, restrictions, conditions, standards, prohibitions,
requirements, obligations, schedules and timetables contained in applicable
Environmental Laws; (iii) as of the date hereof are not aware of nor have
received notice of any past or present violations of Environmental Laws, or any
event, condition, circumstance, activity, practice, incident, action or plan
which is reasonably likely to interfere with or prevent continued compliance
with Environmental Laws or which would give rise to any common law or statutory
liability, or otherwise form the basis of any claim, action, suit or proceeding,
against Parent or any of its subsidiaries based on or resulting from the
manufacture, processing, distribution, use, treatment, storage, disposal,
transport, or handling, or the emission, discharge or release into the
environment, of any pollutant, contaminant or hazardous or toxic material or
waste; and (iv) have taken all actions necessary under applicable Environmental
Laws to register any products or materials required to be registered by Parent
or its subsidiaries (or any of their respective agents) thereunder.
 
     SECTION 3.17  Intellectual Property.  Parent, directly or indirectly, owns,
or is licensed or otherwise possesses legally enforceable rights to use, all
patents, trademarks, trade names, services marks, copyrights, and any
applications therefor, technology, know-how and tangible or intangible
proprietary information or material that are material to the business of Parent
and its subsidiaries as currently conducted by Parent and its subsidiaries (the
"PARENT INTELLECTUAL PROPERTY RIGHTS"). Either Parent or one of its subsidiaries
is the sole and exclusive owner of, or the exclusive or non-exclusive licensee
of, with all right, title and interest in and to (free and clear of any liens or
encumbrances), Parent Intellectual Property Rights, and, in the case of Parent
Intellectual Property Rights owned by Parent or any of its subsidiaries, has
sole and exclusive rights (and is not contractually obligated to pay any
compensation to any third party in respect thereof) to the use thereof or the
material covered thereby in connection with the services or products in respect
of which Parent Intellectual Property Rights are being used. Except as set forth
in Section 3.17 of the Parent Disclosure Schedule, no claims with respect to
Parent Intellectual Property Rights have been asserted or, to the knowledge of
Parent, are threatened by any person that constitute a Material Adverse Effect,
(i) to the effect that the manufacture, sale, licensing or use of any product of
Parent or any of its subsidiaries as now manufactured, used, sold or licensed or
proposed for manufacture, use, sale or license by Parent or any of its
subsidiaries infringes on any copyright, patent, trade mark, service mark or
trade secret, (ii) against the use by Parent or any of its subsidiaries of any
trademarks, trade names, trade secrets, copyrights, patents, technology,
know-how or computer software programs and applications used in Parent's or its
subsidiaries' business as currently conducted or as proposed to be conducted, or
(iii) challenging the ownership or validity of any of Parent Intellectual
Property Rights. All registered trademarks, service marks and copyrights held by
Parent or any of its subsidiaries are valid and subsisting, except to the extent
any failure to be so valid and subsisting does not constitute a Material Adverse
Effect. To the knowledge of Parent, there is no unauthorized use, infringement
or misappropriation of any Parent Intellectual Property Rights by any third
party, including any employee or former employee of Parent or any of its
subsidiaries. No Parent Intellectual Property Right or product of Parent or any
of its subsidiaries is subject to any outstanding decree, order, judgment, or
stipulation restricting in any manner the licensing thereof by Parent or any of
its subsidiaries, except to the extent any such restriction does not constitute
a Material Adverse Effect. Neither Parent nor any of its subsidiaries has
entered into any agreement (other than exclusive distribution agreements) under
which Parent or any of its subsidiaries is restricted from selling, licensing or
otherwise distributing any of its products to any class of
 
                                      A-18

customers, in any geographic area, during any period of time or in any segment
of the market, except to the extent any such restriction does not constitute a
Material Adverse Effect.
 
     SECTION 3.18  Interested Party Transactions.  Except as set forth in
Section 3.18 of the Parent Disclosure Schedule, since the date of Parent's proxy
statement dated March 14, 1996 no event has occurred that would be required to
be reported as a Certain Relationship or Related Transaction, pursuant to Item
404 of Regulation S-K promulgated by the SEC.
 
     SECTION 3.19  Insurance.  All material fire and casualty, general
liability, business interruption, product liability, professional liability and
sprinkler and water damage insurance policies maintained by Parent or any of its
subsidiaries are with reputable insurance carriers, provide full and adequate
coverage for all normal risks incident to the business of Parent and its
subsidiaries and their respective properties and assets and are in character and
amount at least equivalent to that carried by entities engaged in similar
businesses and subject to the same or similar perils or hazards, except as could
not reasonably be expected to have a Material Adverse Effect.
 
     SECTION 3.20  Pooling Matters.  Neither Parent nor any of its affiliates
has taken or agreed to take any action that could affect the ability of Parent
to account for the business combination to be effected by the Merger as a
pooling of interests.
 
     SECTION 3.21  Opinion of Financial Advisor.  Parent has received the
separate opinions of its financial advisors, Merrill Lynch & Co. and J.P. Morgan
& Co. Incorporated, that, as of the date hereof, the Exchange Ratio is fair to
Parent and Parent's stockholders from a financial point of view.
 
     SECTION 3.22  Brokers.  Except as set forth on Section 3.22 of the Parent
Disclosure Schedule, no broker, finder or investment banker or other party is
entitled to any brokerage, finder's or other similar fee or commission in
connection with the transactions contemplated by this Agreement based upon
arrangements made by or on behalf of Parent or Merger Sub or any of their
subsidiaries or affiliates. The fees and expenses of the entities listed on
Section 3.22 of the Parent Disclosure Schedule will be paid by Parent. Parent
has heretofore furnished to the Company a complete and correct copy of all
agreements between Parent and the entities listed on Section 3.22 of the Parent
Disclosure Schedule pursuant to which such firms would be entitled to any
payment relating to the transactions contemplated hereunder.
 
     SECTION 3.23  Ownership of Merger Sub; No Prior Activities.
 
     (a) Merger Sub was formed solely for the purpose of engaging in the
transactions contemplated by this Agreement.
 
     (b) As of the date hereof and the Effective Time, except for obligations or
liabilities incurred in connection with its incorporation or organization and
the transactions contemplated by this Agreement and except for this Agreement
and any other agreements or arrangements contemplated by this Agreement, Merger
Sub has not and will not have incurred, directly or indirectly, through any
subsidiary or affiliate, any obligations or liabilities or engaged in any
business activities of any type or kind whatsoever or entered into any
agreements or arrangements with any person.
 
     SECTION 3.24  Battery Group Headquarters.  Parent's present intention is to
maintain the headquarters of the battery group of the Surviving Corporation in
Bethel, Connecticut.

     make any of the representations or warranties of the Company contained in
     this Agreement untrue or incorrect or prevent the Company from performing
     or cause the Company not to perform its covenants hereunder.
 
     SECTION 4.2  No Solicitation.  (a) The Company shall not, directly or
indirectly, through any officer, director, employee, representative or agent of
the Company or any of its subsidiaries, (i) solicit, initiate or encourage the
initiation of any inquiries or proposals regarding any merger, sale of
substantial assets, sale of shares of capital stock (including without

"ACQUISITION PROPOSAL"), (ii) engage in negotiations or discussions concerning,
or provide any nonpublic information to any person relating to, any Acquisition
Proposal or (iii) agree to, approve or recommend any Acquisition Proposal.
Nothing contained in this Section 4.2(a) shall prevent the Board of Directors of
the Company from considering, negotiating, discussing, approving and
recommending to the stockholders of the Company a bona fide Acquisition Proposal
not solicited in violation of this Agreement, provided the Board of Directors of
the Company determines in good faith (upon advice of outside counsel) that it is
required to do so in order to discharge properly its fiduciary duties. Nothing

Company from complying with Rule 14e-2 promulgated under the Exchange Act with
regard to a tender or exchange offer.
 
     (b) The Company shall immediately notify Parent after receipt of any
Acquisition Proposal, or any modification of or amendment to any Acquisition
Proposal, or any request for nonpublic information relating to the Company or
any of its subsidiaries in connection with an Acquisition Proposal or for access
to the properties, books or records of the Company or any subsidiary by any
person or entity that informs the Board of Directors of the Company or such
subsidiary that it is considering making, or has made, an Acquisition Proposal.
Such notice to Parent shall be made orally and in writing, and shall indicate
whether the Company is
 
                                      A-21
<PAGE>   109
 
providing or intends to provide the person making the Acquisition Proposal with
access to information concerning the Company as provided in Section 4.2(c).
 
     (c) If the Board of Directors of the Company receives a request for
material nonpublic information by a person who makes, or indicates that it is
considering making, a bona fide Acquisition Proposal, and the Board of Directors
determines in good faith and upon the advice of outside counsel that it is
required to cause the Company to act as provided in this Section 4.2(c) in order
to discharge properly the directors' fiduciary duties, then, provided such
person has executed a confidentiality agreement substantially similar to the one
then in effect between the Company and Parent (other than for any provisions
similar to the provisions of Sections 7 and 8 of the Confidentiality Letter),
the Company may provide such person with access to information regarding the
Company.
 
     (d) The Company shall immediately cease and cause to be terminated any
existing discussions or negotiations with any persons (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 the confidentiality
provisions of any confidentiality agreement to which the Company is a party.
 
     (e) The Company shall ensure that the officers, directors and employees of
the Company and its subsidiaries and any investment banker or other advisor or
representative retained by the Company are aware of the restrictions described
in this Section 4.2.

its business, and cause the businesses of its subsidiaries to be conducted, in
the ordinary course, other than actions taken by Parent or its subsidiaries in
contemplation of the Merger, and Parent shall use all reasonable efforts to
preserve substantially intact the business organization of Parent and its
subsidiaries, to keep available all services of the present officers, employees
and consultants of Parent and its subsidiaries and to preserve the present
relationships of the Parent and its subsidiaries with customers, suppliers and
other persons with which Parent or any of its subsidiaries has significant
business relations. By way of amplification and not limitation, except as
contemplated by this Agreement, neither Parent nor any of its subsidiaries
shall, during the period from the date of this Agreement and continuing until
the earlier of the termination of this Agreement or the Effective Time, directly
or indirectly do, or propose to do, any of the following without the prior
written consent of the Company:
 
          (a) declare, set aside, make or pay any dividend or other distribution
     (whether in cash, stock or property or any combination thereof) in respect
     of any of its capital stock, other than regular quarterly cash dividends of
     $0.18 per share consistent with past practices and except that a wholly
     owned subsidiary of Parent may declare and pay a dividend to its parent;
 
          (b) take or agree in writing or otherwise to take any action which
     would make any of the representations or warranties of Parent contained in
     this Agreement untrue or incorrect or prevent Parent from performing or
     cause Parent not to perform its covenants hereunder; or
 
          (c) amend or otherwise change the Certificate of Incorporation or
     By-Laws of Parent in a manner that would be materially adverse to the
     holders of Parent Common Stock (it being understood that any such amendment
     made to implement a so-called "shareholder rights plan" as described in the
     footnotes to the financial statements included in or incorporated by
     reference into the Annual Report of Parent on Form 10-K for the fiscal year
     ended December 31, 1995 shall not be deemed to be materially adverse to the
     holders of Parent Common Stock).

the Effective Time were directors, officers, employees or agents of the Company,
unless such modification is required by law.
 
     (b) The Company shall, to the fullest extent permitted under applicable law
or under the Company's Certificate of Incorporation or By-Laws and regardless of

the Effective Time, Parent and the Surviving Corporation shall, to the fullest
extent permitted under applicable law or under the Surviving Corporation's
Certificate of Incorporation or By-Laws as in effect at the Effective Time,
indemnify and hold harmless, each present and former director, officer or
employee of the Company or any of its subsidiaries (collectively, the
"INDEMNIFIED PARTIES") against any costs or expenses (including attorneys'
fees), judgments, fines, losses, claims, damages, liabilities and amounts paid
in settlement in connection with any claim, action, suit, proceeding or

the Effective Time, to the same extent as provided in the Company's Certificate
of Incorporation or By-Laws or any applicable contract or agreement as in effect
on the date hereof, in each case for a period of six years after the date
hereof. In the event of any such claim, action, suit, proceeding or
investigation (whether arising before or after the Effective Time), (i) any
counsel retained by the Indemnified Parties for any period after the Effective
Time shall be reasonably satisfactory to the Surviving Corporation, (ii) after

be unreasonably withheld); and provided, further, that, in the event that any
claim or claims for indemnification are asserted or made within such six-year
period, all rights to indemnification in respect of any such claim or claims
shall continue until the disposition of any and all such claims. The Indemnified
Parties as a group may retain only one law firm to represent them with respect
to any single action unless there is, under applicable standards of professional
conduct, a conflict on any significant issue between the positions of any two or
more Indemnified Parties.

respects the obligations of the Company pursuant to indemnification agreements
with the Company's directors and officers existing at or before the Effective
Time.

the Surviving Corporation to maintain in effect, if available, directors' and
officers' liability insurance covering those persons who are currently covered
by the Company's directors' and officers' liability insurance policy (a copy of
which has been
 
                                      A-24

made available to Parent) on terms comparable to those now applicable to
directors and officers of the Company; provided, however, that in no event shall
Parent or the Surviving Corporation be required to expend in excess of 150% of
the annual premium currently paid by the Company for such coverage; and provided
further, that if the premium for such coverage exceeds such amount, Parent or
the Surviving Corporation shall purchase a policy with the greatest coverage
available for such 150% of the annual premium.

agreements for which those provided in Schedule 5.7A(b) shall be substituted;
provided, however, that nothing herein shall affect Parent's rights to modify or
terminate any such Benefit Plan at or after the end of such one (1) year period.
On and after the Effective Time, employees of the Surviving Corporation who were
employees on the Effective Date will be eligible to participate in Parent's
stock option and annual incentive plans as in effect from time to time at levels
commensurate with their responsibilities and consistent with the terms of such
plans.
 
     (b) Effective no later than the Effective Time, the Company shall enter
into agreements and adopt plans or programs in forms satisfactory to Parent, the
terms and conditions of which shall be consistent in all material respects with
those set forth in Schedule 5.7A(b) to provide in a manner consistent with the
transaction contemplated hereby the benefits and payments to each person or
category of persons identified on such Schedule 5.7A(b).
 
     SECTION 5.8  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 nonoccurrence of any event the occurrence or nonoccurrence
of which would be likely to cause any representation or warranty contained in
this Agreement to become materially untrue or inaccurate, or (ii) any failure of
the Company, Parent or Merger Sub, as the case may be, materially to 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 provided further that failure
to give such notice shall not be treated as a breach of covenant for the
purposes of Sections 6.2(a) or 6.3(a) unless the failure to give such notice
results in material prejudice to the other party.
 
     SECTION 5.9  Further Action/Tax Treatment.  Upon the terms and subject to
the conditions hereof each of the parties hereto shall use all reasonable
efforts to take, or cause to be taken, all actions and to do, or cause to be

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 otherwise
to satisfy or cause to be satisfied all conditions precedent to its obligations
under this Agreement. 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 to its knowledge could
reasonably be expected to prevent the Merger from qualifying, as a
reorganization under the provisions of Section 368 of the Code.
 
     SECTION 5.10  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 outside counsel be required by law or the
rules and regulations of the NYSE.

Company, as the case may be, a letter, dated within 2 business days of the
Effective Date of the Registration Statement covering such matters as are
requested by Parent or the Company, as the case may be, and as are customarily
addressed in accountant's "comfort" letters. In connection with Parent's efforts
to obtain such letter, if requested by KPMG Peat Marwick LLP, the Company shall
provide a representation letter to KPMG Peat Marwick LLP complying with the
statement on Auditing Standards No. 72 ("SAS 72"), if then required. In
connection with the Company's efforts to obtain such letter, if requested by

& Touche LLP complying with SAS 72, if then required.
 
     SECTION 5.13  Pooling Accounting Treatment.  Each of Parent and the Company
agrees not to take any action that to its knowledge could reasonably be expected
to adversely affect the ability of Parent to treat the Merger as a pooling of
interests, and each of Parent and the Company agrees to take such action as may
be reasonably required to negate the impact of any past actions which to its
knowledge could reasonably be expected to adversely impact the ability of Parent
to treat the Merger as a pooling of interests.

continue the listing of the Company Common Stock on the NYSE during the term of
this Agreement.

                                  TERMINATION
 
     SECTION 7.1  Termination.  This Agreement may be terminated at any time
prior to the Effective Time, notwithstanding approval thereof by the
stockholders of the Company or Parent:
 
          (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 March 31, 1997 (provided that the right to terminate this
     Agreement under this Section 7.1(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 nonappealable 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 right to
     terminate this Agreement under this Section 7.1(c) shall not be available
     to any party who has not complied with its obligations under Section 5.9
     and such noncompliance materially contributed to the issuance of any such
     order, decree or ruling or the taking of such action); or
 
          (d) (i) by Parent, if the requisite vote of the stockholders of the
     Company shall not have been obtained at a duly held meeting of such
     stockholders or any adjournment thereof by March 31, 1997 or (ii) by the
     Company, if the requisite vote of the stockholders of Parent shall not have
     been obtained at a duly held meeting of such stockholders or any
     adjournment thereof by March 31, 1997; or
 
          (e) by Parent or the Company, if: (i) the Board of Directors of the
     Company shall withdraw, modify or change its approval or recommendation of
     this Agreement or the Merger in a manner adverse to Parent or shall have
     resolved to do so in accordance with Section 5.3 hereof; (ii) the Board of
     Directors of the Company shall have recommended to the stockholders of the
     Company an Alternative Transaction (as defined below); or (iii) a tender
     offer or exchange offer for 15% or more of the outstanding shares of
     Company Common Stock is commenced (other than by Parent or an affiliate of
     Parent) and the Board of Directors of the Company recommends that the
     stockholders of the Company tender their shares in such tender or exchange
     offer; provided, that, the Company shall not be entitled to exercise any
     termination rights under clause (ii) or (iii) of this Section 7.1(e) unless
     (x) any action of the Board of Directors of the Company referred to in
     either such clause is required to be taken by the Board of Directors in
     order to properly discharge its fiduciary duties and (y) the Company has
     complied with its obligations in Section 4.2; or
 
          (f) by the Company, if the Board of Directors of Parent shall
     withdraw, modify or change its approval or recommendation of this Agreement
     or the Merger in a manner adverse to the Company or shall have resolved to
     do so in accordance with Section 5.3 hereof.
 
     As used herein, "Alternative Transaction" means any of (i) a transaction or
series of transactions pursuant to which any person (or group of persons) other
than Parent or its subsidiaries and other than Kohlberg Kravis Roberts & Co. and
its affiliates (a "THIRD PARTY") acquires or would acquire more than 15% of the
outstanding Shares, whether from the Company or pursuant to a tender offer or
exchange offer or otherwise, (ii) any acquisition or proposed acquisition of the
Company or any of its significant subsidiaries by
 
                                      A-28
<PAGE>   116
 
a merger or other business combination (including any so-called "merger of
equals" and whether or not the Company or any of its significant subsidiaries is
the entity surviving any such merger or business combination) or (iii) any other
transaction pursuant to which any Third Party acquires or would acquire control
of assets (including for this purpose the outstanding equity securities of
subsidiaries of the Company and any entity surviving any merger or business
combination including any of them) of the Company or any of its subsidiaries
having a fair market value equal to more than 35% of the fair market value of
all the assets of the Company and its subsidiaries, taken as a whole,
immediately prior to such transaction.
 
     SECTION 7.2  Effect of Termination.  In the event of the termination of
this Agreement pursuant to Section 7.1, 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
Section 7.3 hereof, and (ii) nothing herein shall relieve any party from
liability for any breach hereof occurring prior to termination. The

all fees and expenses, other than accountants' and attorneys' fees, incurred in
connection with the printing and filing of the Joint Proxy Statement/Prospectus
(including any preliminary materials related thereto) and the Registration
Statement (including financial statements and exhibits) and any amendments or
supplements thereto.
 
     (b) The Company shall pay Parent a fee of $150 million (the "FEE"), plus
actual, documented and reasonable out-of-pocket expenses of Parent relating to
the transactions contemplated by this Agreement not in excess of $15 million in
the aggregate (including, but not limited to, reasonable fees and expenses of
Parent's counsel, accountants and financial advisers) ("EXPENSES"), upon the
termination of this Agreement by Parent or the Company pursuant to Section
7.1(e)(ii) or Section 7.1(e)(iii).
 
     (c) The Company shall pay Parent the Fee plus the Expenses if all of the
following events have occurred:
 
          (i) a bona fide Alternative Transaction is publicly commenced,

     Company at any time on or after the date of this Agreement and on or prior
     to the date of the meeting of the stockholders of the Company referred to
     in Section 5.3 hereof (including the last date on which any adjourned
     session thereof is reconvened);
 
          (ii) either Parent or the Company terminates this Agreement pursuant
     to Section 7.1(b) or Parent terminates this Agreement pursuant to Section
     7.1(d)(i) if, in the case of termination under either such Section, the
     requisite vote for approval and adoption of the Merger Agreement by the
     stockholders of the Company shall not have been obtained by March 31, 1997;
     and
 
          (iii) thereafter on or prior to the second anniversary of the date of
     termination, (A) such Alternative Transaction is consummated or (B) there
     is consummated any transaction, whether or not commenced, publicly
     disclosed, publicly proposed or communicated to the Company prior to such
     termination, that would constitute an Alternative Transaction (provided
     that for purposes of this clause (iii)(B) of Section 7.3(c) the reference
     to the percentage of outstanding Shares in clause (i) of the definition of
     Alternative Transaction shall be 50% instead of 15%).
 
     (d) The Company shall pay Parent the Fee plus the Expenses if Parent or the
Company terminates this Agreement pursuant to clause (i) of Section 7.1(e) and
thereafter on or prior to the second anniversary of the date of termination
there is consummated a transaction that would constitute an Alternative
Transaction (provided that for purposes of this Section 7.3(d) the reference to
the percentage of outstanding Shares in clause (i) of the definition of
Alternative Transaction shall be 50% instead of 15%);
 
     (e) The Fee and Expenses payable pursuant to Section 7.3(b) shall be paid
within one business day after the first to occur of any of the events described
in Section 7.3(b). The Fee and Expenses payable pursuant to Section 7.3(c) or

Alternative Transaction. Notwithstanding the preceding sentences, in no event
shall the Company be required to pay any such Fee and Expenses to Parent if,
immediately prior to the termination of this Agreement, Parent was in material
breach of its obligations under this Agreement.

under this Agreement are cumulative to, and not exclusive of, any rights or
remedies otherwise available.

Prudential Tower Building
Boston, MA 02199
 
Dear Lady and Gentlemen:
 
     The Gillette Company (the "Company"), Alaska Acquisition Corp., a wholly
owned subsidiary of the Company (the "Sub"), and Duracell International Inc.
(the "Subject Company") propose to enter into an Agreement and Plan of Merger
(the "Agreement") providing for the merger of the Sub with and into the Subject
Company in a transaction (the "Merger") in which each share of the Subject
Company's Common Stock, par value $.01 (the "Shares"), shall be converted into
the right to receive .904 shares of the Company's Common Stock, $1.00 par value
(the "Company Shares").
 
     You have asked us whether, in our opinion, the proposed consideration to be
paid by the Company pursuant to the Merger is fair to the Company from a
financial point of view.
 
     In arriving at the opinion set forth below, we have, among other things:
 
          (1) Reviewed the Subject Company's and the Company's Annual Reports,
     Forms 10-K and related information for the three fiscal years ended June
     30, 1995 and December 31, 1995, respectively, the unaudited financial
     information for the nine months ended March 31, 1996 and the six months
     ended June 30, 1996, respectively, and a draft of the Subject Company's
     financial statements and related Management's Discussion and Analysis for
     the fiscal year ended June 30, 1996;
 
          (2) Reviewed certain information, including information relating to
     the future prospects of the Subject Company and the Company and furnished
     to us by the Subject Company's and the Company's management;
 
          (3) Conducted discussions with members of senior management of the
     Subject Company and the Company concerning the business and prospects of
     the Subject Company and the Company;
 
          (4) Reviewed the historical market prices and trading activity for the
     Shares and the Company Shares and compared them with that of certain
     publicly traded companies which we deemed to be comparable to the Subject
     Company and the Company, respectively;
 
          (5) Compared the results of operations of the Subject Company with
     that of certain companies which we deemed to be comparable to the Subject
     Company;
 
          (6) Compared the proposed financial terms of the transaction
     contemplated by the Agreement with the financial terms of certain other
     mergers and acquisitions which we deemed to be comparable;
 
          (7) Considered the pro forma effects of the Merger on the Company's
     capitalization ratios, earnings and cash flow;
 
          (8) Reviewed a draft of the Agreement dated September 12, 1996; and
 
          (9) Reviewed such other financial studies and analyses and performed
     such other investigations and took into account such other matters as we
     deemed necessary.

     In preparing our opinion, we have relied upon and assumed, without
independent verification, the accuracy and completeness of all information that
was publicly available or was supplied or otherwise made available to us by the
Subject Company and the Company or otherwise reviewed by us, and we have not
assumed any responsibility or liability therefor. We have not conducted any
valuation or appraisal of any assets or liabilities of the Subject Company or
the Company, nor have any such valuations or appraisals been provided to us. In
addition, we have not made any physical inspections of the properties or assets
of the Subject Company or the Company. With respect to the information relating
to the future prospects of the Subject Company and the Company furnished by the
Subject Company and the Company, we have assumed that such information has been
reasonably prepared based on assumptions reflecting the best currently available
estimates and judgments by the Subject Company's and the Company's management,
respectively, as to the expected future prospects of the Subject Company and the
Company to which such information relates. We have also assumed that the Merger
will constitute a reorganization within the meaning of Section 368 of the
Internal Revenue Code of 1986, as amended, and qualify for accounting treatment
as a pooling of interests. We have relied as to all legal matters relevant to
rendering our opinion upon the advice of counsel.
 
     Our opinion is necessarily based on economic, market and other conditions
as in effect on, and the information made available to us as of, the date
hereof. It should be understood that subsequent developments may affect this
opinion and that we do not have any obligation to update, revise or reaffirm
this opinion. We are expressing no opinion herein as to the price at which the
Company's stock will trade at any future time.
 
     We have acted as financial advisor to the Company with respect to the
Merger and will receive a fee from the Company for our services. We have, in the
past, provided financial advisory and financing services to the Subject Company
and the Company and we have received fees for the rendering of such services. In
addition, in the ordinary course of our business, we or our affiliates may
actively trade the debt and equity securities (including the Shares and the
Company Shares) for our or our affiliates' own account and for the account of
customers and, accordingly, may at any time hold a long or short position in
such securities.
 
     This letter is provided to the Board of Directors of the Company in
connection with and for the purposes of its evaluation of the Merger. This
opinion does not constitute a recommendation to any stockholder of the Company
as to how such stockholder should vote with respect to the Merger. This opinion
may not be disclosed, referred to, or communicated (in whole or in part) to any
third party for any purpose whatsoever except with our prior written consent in
each instance. This opinion may be reproduced in full in any proxy or
information statement mailed to stockholders of the Company and in any
registration statement related to the Merger filed by the Company with the
Securities and Exchange Commission pursuant to the Securities Act of 1933 but
may not otherwise be disclosed publicly in any manner without our prior written
approval and must be treated as confidential.
 
     On the basis of, and subject to the foregoing, we are of the opinion that
the proposed consideration to be paid by the Company pursuant to the Merger is
fair to the Company from a financial point of view.

Boston, MA 02199
Dear Ladies and Gentlemen:
 
     The Gillette Company (the "Company"), Merger Sub, a wholly owned subsidiary
of the Company (the "Sub"), and Duracell International Inc. (the "Subject
Company") propose to enter into an Agreement and Plan of Merger (the
"Agreement") providing for the merger of the Merger Sub with and into the
Subject Company in a transaction (the "Merger") in which each share of the
Subject Company's Common Stock, par value $.01 (the "Shares"), shall be
converted into the right to receive 0.904 shares of the Company's Common Stock,
$1.00 par value (the "Company Shares").
 
     You have asked us whether, in our opinion, the proposed consideration to be
paid by the Company pursuant to the Merger is fair to the Company from a
financial point of view.
 
     In arriving at the opinion set forth below, we have, among other things:
 
          (1) reviewed the Subject Company's and the Company's Annual Reports,
     Forms 10-K and related information for the three fiscal years ended June
     30, 1995 and December 31, 1995, respectively, the unaudited financial
     information for the nine months ended March 31, 1996 and the six months
     ended June 30, 1996, respectively, and a draft of the Subject Company's
     financial statements and related Management's Discussion and Analysis for
     the fiscal year ended June 30, 1996;
 
          (2) reviewed certain information, including information relating to
     the future prospects of the Subject Company and the Company and furnished
     to us by the Subject Company's and the Company's management;
 
          (3) conducted discussions with members of senior management of the
     Subject Company and the Company concerning the business and prospects of
     the Subject Company and the Company;
 
          (4) reviewed the historical market prices and trading activity for the
     Shares and the Company Shares and compared them with that of certain
     publicly traded companies which we deemed to be comparable to the Subject
     Company and the Company, respectively;
 
          (5) compared the results of operations of the Subject Company with
     that of certain companies which we deemed to be comparable to the Subject
     Company;
 
          (6) compared the proposed financial terms of the transaction
     contemplated by the Agreement with the financial terms of certain other
     mergers and acquisitions which we deemed to be comparable;
 
          (7) considered the pro forma effects of the Merger on the Company's
     capitalization ratios, earnings and cash flow;

          (8) reviewed a draft of the Agreement dated September 12, 1996; and
 
          (9) reviewed such other financial studies and analyses and performed
     such other investigations and took into account such other matters as we
     deemed necessary.
 
     In preparing our opinion, we have relied upon and assumed, without
independent verification, the accuracy and completeness of all information that
was publicly available or was supplied or otherwise made available to us by the
Subject Company and the Company or otherwise reviewed by us, and we have not
assumed any responsibility or liability therefor. We have not conducted any
valuation or appraisal of any assets or liabilities of the Subject Company or
the Company, nor have any such valuations or appraisals been provided to us. In
addition, we have not made any physical inspections of the properties or assets
of the Subject Company or the Company. With respect to the information relating

Subject Company and the Company, we have assumed that such information has been
reasonably prepared based on assumptions reflecting the best currently available
estimates and judgments by the Subject Company's and the Company's management,
respectively, as to the expected future prospects of the Subject Company and the
Company to which such information relates. We have also assumed that the Merger
will constitute a reorganization within the meaning of Section 368 of the
Internal Revenue Code of 1986, as amended, and qualify for accounting treatment
as a pooling of interests. We have relied as to all legal matters relevant to
rendering our opinion upon the advice of counsel.

as in effect on, and the information made available to us as of, the date
hereof. It should be understood that subsequent developments may affect this
opinion and that we do not have any obligation to update, revise, or reaffirm
this opinion. We are expressing no opinion herein as to the price at which the
Company's stock will trade at any future time.
 
     We have acted as financial advisor to the Company with respect to the
Merger and will receive a fee from the Company for our services. Our affiliate,
Morgan Guaranty Trust Company of New York, has been the agent bank on the
Company's revolving credit facilities since 1986 and has received fees for such
services. We and our affiliates have also provided other financial services to
the Company in the past and have received fees for such services. In addition,
in the ordinary course of our business, we or our affiliates may actively trade
the debt and equity securities (including the Shares and the Company Shares) for
our or our affiliates' own account and for the account of customers and,
accordingly, may at any time hold a long or short position in such securities.
 
     This letter is provided to the Board of Directors of the Company in
connection with and for the purposes of its evaluation of the Merger. This
opinion does not constitute a recommendation to any stockholder of the Company
as to how such stockholder should vote with respect to the Merger. This opinion

registration statement related to the Merger filed by the Company with the
Securities and Exchange Commission pursuant to the Securities Act of 1933 but
may not otherwise be disclosed publicly in any manner without our prior written
approval and must be treated as confidential.
 
     On the basis of, and subject to the foregoing, we are of the opinion that
the proposed consideration to be paid by the Company pursuant to the Merger is
fair to the Company from a financial point of view.
Very truly yours,

Board of Directors
Duracell International Inc.
Berkshire Corporate Park
Bethel, CT 06801
 
Gentlemen and Madam:
 
     We understand that Duracell International Inc. ("Duracell"), The Gillette
Company ("Gillette") and a wholly-owned subsidiary of Gillette ("Merger Sub")
have entered into an Agreement and Plan of Merger dated as of September 12, 1996
(the "Merger Agreement"), which provides, among other things, for the merger
(the "Merger") of Merger Sub with and into Duracell, as a result of which
Duracell will become a wholly-owned subsidiary of Gillette. Pursuant to the
Merger, each outstanding share of common stock, par value $0.01 per share, of
Duracell ("Duracell Common Stock"), other than shares of Duracell Common Stock
held in the treasury or any shares held by Gillette or any wholly-owned
subsidiary of Duracell or Gillette, will be converted into 0.9040 shares (the
"Exchange Ratio") of common stock par value $1.00 per share, of Gillette
("Gillette Common Stock"). The terms and conditions of the Merger are more fully
set forth in the Merger Agreement.
 
     You have asked for our opinion as to whether the Exchange Ratio pursuant to
the Merger Agreement is fair from a financial point of view to the holders of
shares of Duracell Common Stock.
 
     For purposes of the opinion set forth herein, we have:
 
          (i) analyzed certain publicly available financial statements and other
     information of Duracell and Gillette;
 
          (ii) analyzed certain internal financial statements and other
     financial and operating data concerning Duracell prepared by the management
     of Duracell;
 
          (iii) analyzed certain financial projections prepared by the
     management of Duracell;
 
          (iv) discussed the past and current operations and financial condition
     and the prospects of Duracell with senior executives of Duracell;
 
          (v) discussed the past and current operations and financial condition
     and the prospects of Gillette with senior executives of Gillette and
     analyzed the proforma impact of the Merger on Gillette's earnings per
     share;
 
          (vi) reviewed the reported prices and trading activity for Duracell
     Common Stock and Gillette Common Stock;
 
          (vii) compared the financial performance of Duracell and the prices
     and trading activity of Duracell Common Stock with that of certain other
     comparable publicly-traded companies and their securities;
 
          (viii) reviewed the financial terms, to the extent publicly available,
     of certain comparable acquisition transactions;
 
          (ix) discussed with senior executives of Duracell and Gillette their
     views of the strategic rationale for the Merger and the economic benefits
     of the Merger to Gillette;

          (x) participated in discussions and negotiations among representatives
     of Duracell and Gillette and their financial and legal advisors;
 
          (xi) reviewed the Merger Agreement; and
 
          (xii) performed such other analyses as we have deemed appropriate.
 
     We have assumed and relied upon without independent verification the
accuracy and completeness of the information reviewed by us for the purposes of
this opinion. With respect to the financial projections, we have assumed that
they have been reasonably prepared on bases reflecting the best currently
available estimates and judgments of the future financial performance of
Duracell. We have relied upon, with your consent, the assumptions of the
management of Duracell and Gillette regarding cost savings and other synergies
that will result from the Merger. We have not made any independent valuation or
appraisal of the assets or liabilities of Duracell, nor have we been furnished
with any such appraisals. We have assumed that the Merger will be treated as a
"pooling-of-interests" business combination in accordance with U.S. Generally
Accepted Accounting Principles and will qualify as a "reorganization" within the
meaning of Section 368(a) of the Internal Revenue Code of 1986. We have also
assumed that the Merger will be consummated in accordance with the terms set
forth in the Merger Agreement. Our opinion is necessarily based on economic,
market and other conditions as in effect on, and the information made available
to us as of, the date hereof. In arriving at our opinion, we were not authorized
to solicit, and did not solicit, interest from any party with respect to the
acquisition of Duracell.
 
     We have acted as financial advisor to the Board of Directors of Duracell in
connection with this transaction and will receive a fee for our services. It is
understood that this letter is for the information of the Board of Directors of
Duracell and may not be used for any other purpose without our prior written
consent, except that this opinion may be included in its entirety in any filing
made by Duracell with the Securities and Exchange Commission with respect to the
Merger. In addition, we express no opinion and make no recommendation as to how
the holders of Duracell Common Stock should vote at the stockholders' meeting
held in connection with the Merger.
 
     Based on and subject to the foregoing, we are of the opinion on the date
hereof that the Exchange Ratio pursuant to the Merger Agreement is fair from a
financial point of view to the holders of shares of Duracell Common Stock.
 
                                            Very truly yours,

ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
     Section 145 of the Delaware General Corporation Law, as amended (the
"DGCL"), provides that a corporation may indemnify any person who was or is a
party or is threatened to be made a party to any threatened, pending or
completed action, suit or proceeding, whether civil, criminal or investigative
(other than an action by or in the right of the corporation) by reason of the
fact that he or she is or was a director, officer, employee or agent of the
corporation, or is or was serving at the request of the corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise, against expenses (including attorneys'
fees), judgments, fines and amount paid in settlement actually and reasonably
incurred by him or her in connection with such action, suit or proceeding if he
or she acted in good faith and in a manner he or she reasonably believed to be
in or not opposed to the best interests of the corporation, and, with respect to
any criminal action or proceeding, had no reasonable cause to believe his or her
conduct was unlawful. Section 145 further provides that a corporation similarly
may indemnify any such person serving in any such capacity 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, against expenses (including attorneys' fees) actually and reasonably
incurred in connection with the defense or settlement of such action or suit if
he or she acted in good faith and in a manner he or she reasonably believed to
be in or not opposed to the best interests of the corporation, except that no
indemnification shall be made in respect of any claim, issue or matter as to
which such person shall have been adjudged to be liable to the corporation
unless and only to the extent that the Delaware Court of Chancery or such other
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 reasonable entitled to indemnity for such
expenses which the Court of Chancery or such other court shall deem proper.
 
     Section 102(b)(7) of the DGCL permits a corporation to include in its
certificate of incorporating a provision eliminating or limiting the personal
liability of a director to the corporation or its stockholders for monetary
damages for breach of fiduciary duty as a director, provided that such provision
shall not eliminate or limit the liability of a director (i) for any breach of
the director's duty of loyalty to the corporation or its stockholders, (ii) for
acts or omissions not in good faith or which involve intentional misconduct or a
knowing violation of law, (iii) under Section 174 of the DGCL (relating to
unlawful payment of dividends and unlawful stock purchase and redemption) or
(iv) for any transaction from which the director derived an improper personal
benefit.
 
     The Registrant's By-laws provide that the Registrant shall indemnify
current or former directors, officers, employees or agents of the Registrant, in
connection with proceedings brought against such persons by reason of their
position with the Registrant to the fullest extent permitted by Delaware law.
The Registrant's Certificate of Incorporation, as amended, provides that a
director of the Registrant shall not be liable to the Registrant or its
stockholders for monetary damages for breach of fiduciary duty as a director,
except as is not permitted under the DGCL.
 
     The Registrant has obtained an insurance policy that insures its directors
and officers against certain liabilities.

ITEM 22.  UNDERTAKINGS.
 
     (a) The undersigned registrant hereby undertakes:
 
     (1) To file, during any period in which offers or sales are being made, a
post-effective amendment to this registration statement:
 
          (i) To include any prospectus required by Section 10(a)(3) of the
     Securities Act of 1933;
 
          (ii) To reflect in the prospectus any facts or events arising after
     the effective date of the registration statement (or the most recent
     post-effective amendment thereof) which, individually or in the aggregate,
     represent a fundamental change in the information set forth in the
     registration statement. Notwithstanding the foregoing, any increase or
     decrease in volume of securities offered (if the total dollar value of
     securities offered would not exceed that which was registered) and any
     deviation from the low or high and of the estimated maximum offering range
     may be reflected in the form of prospectus filed with the Commission
     pursuant to Rule 424(b) if, in the aggregate, the changes in volume and
     price represent no more than 20 percent change in the maximum aggregate
     offering price set forth in the "Calculation of Registration Fee" table in
     the effective registration statement; and
 
          (iii) To include any material information with respect to the plan of
     distribution not previously disclosed in the registration statement or any
     material change to such information in the registration statement.
 
     (2) That, for the purpose of determining any liability under the Securities
Act of 1933, each such post-effective amendment shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.
 
     (3) To remove from registration by means of a post-effective amendment any
of the securities being registered within remain unsold at the termination of
the offering.
 
     (b) The undersigned registration hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities
Exchange Act of 1934 (and, where applicable, each filing of an employee benefit
plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of
1934) that is incorporated by reference in the registration statement shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.
 
     (c)(1) 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 a 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 other items of the applicable form.
 
     (2) The registrant undertakes that every prospectus: (i) that is filed
pursuant to paragraph (1) immediately preceding, or (ii) that purports to meet
the requirements of Section 10(a)(3) of the Act and is
 
                                      II-3
<PAGE>   130
 
used in connection with an offering of securities subject to Rule 415, will be
filed as a 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 Securities Act of 1933, each such post-effective
amendment shall be deemed to be a new registration statement relating to the
securities offered therein, and the offering of such securities at that time
shall be deemed to be the initial bona fide offering thereof.
 
     (b) The undersigned registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Item 4, 10(b), 11, or 13 of this form, within 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.
 
     (e) 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 subject of and included in
the registration statement when it became effective.
 
     (f) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the registrant pursuant to the foregoing provisions, or otherwise, the
registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the 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:   Registration Statement on Form S-4
              ----------------------------------

Ladies and Gentlemen:

        This opinion is furnished to you in connection with a registration
statement on Form S-4 (the "Registration Statement") filed with the Securities
and Exchange Commission (the "Commission") under the Securities Act of 1933, as
amended, for the registration of 114,160,951 shares of common stock, $1.00 par
value per share (the "Shares"), of The Gillette Company, a Delaware corporation
(the "Company"). The Shares are to be issued in connection with the Agreement
and Plan of Merger dated as of September 12, 1996 (the "Merger Agreement") by
and among the Company, Duracell International Inc. ("Duracell") and Alaska
Acquisition Corp., a wholly-owned subsidiary of the Company and a Delaware
corporation ("Sub"). The Merger Agreement provides for Sub to merge with and
into Duracell (the "Merger") and for Duracell to survive the Merger as a
wholly-owned subsidiary of the Company.

        I am Vice Chairman of the Board and Chief Legal Officer of the Company.
In that capacity, I have acted as counsel for the Company in connection with
the issuance of the Shares pursuant to the Merger. For purposes of this
opinion, I have examined or caused to be examined by counsel retained by or on
staff of the Company, among other things, originals or copies, certified or
otherwise identified to my satisfaction, of such documents as I have deemed
necessary or appropriate as a basis for the opinions set forth herein.

        I am a member of the bar of The Commonwealth of Massachusetts and the
State of Ohio. This opinion is limited to the federal laws of the United States
of America, the laws of The Commonwealth of Massachusetts and the General
Corporation Law of the State of Delaware.

<PAGE>   2

        Based upon the foregoing, I am of the opinion that the Shares being
issued by the Company have been duly authorized and, when issued in accordance
with the Merger Agreement, will be legally issued, fully paid and
nonassessable.

        I hereby consent to the filing of this opinion as part of the
Registration Statement, including but not limited to as an exhibit thereto, and
to the use of my name therein and in the related joint proxy
statement/prospectus under the caption "Legal Matters."

        This opinion is to be used only in connection with the issuance of the
Shares while the Registration Statement is in effect.


                                                Very truly yours,


                                                /s/ Joseph E. Mullaney, Esq.

        Re:     Joint Proxy Statement of The Gillette Company and Duracell
                International, Inc. --- Prospectus of the Gillette Company
                --------------------------------------------------------------

Ladies and Gentlemen:

        We have acted as counsel to The Gillette Company ("Gillette") in
connection with the Registration Statement on Form S-4 of Gillette to which
this opinion appears as an exhibit (the "Registration Statement"), which
includes the Joint Proxy Statement of Gillette and Duracell International Inc.
("Duracell") and Prospectus of Gillette (the "Proxy Statement/Prospectus").
Unless otherwise indicated, any defined term used herein shall have the same
meaning as in the Proxy Statement/Prospectus.

        We hereby confirm that, in our opinion, the following is an accurate
description of the material United States Federal income tax consequences of
the Merger, assuming the due receipt and accuracy of representations as
described under the heading "The Merger -- Certain United States Federal Income
Tax Consequences" in the Proxy Statement/Prospectus:

            1.  No gain or loss will be recognized by a Duracell stockholder
        upon the exchange of his or her Duracell Common Stock for Gillette
        Common Stock, except that a Duracell stockholder who receives cash
        proceeds in lieu of a fractional share interest in Gillette Common Stock
        will recognize gain or loss equal to the difference between such
        proceeds and the tax basis allocated to the fractional share interest.
        Such gain or loss will constitute capital gain or loss if such
        stockholder's Duracell Common Stock is held as a capital asset at the
        Effective Time and will be long-term capital gain or loss if such
        stockholder's Duracell Common Stock has been held for more than one year
        at the Effective Time.

            2.  The tax basis of the Gillette Common Stock received by a
        Duracell stockholder will be the same as such stockholder's tax basis in
        the Duracell Common Stock surrendered in exchange therefore, decreased
        by the tax basis allocated to any fractional share interest exchanged
        for cash.

            3.  The holding period of the Gillette Common Stock received by a
        Duracell stockholder will include the period during which the Duracell
        Common Stock surrendered in exchange therefor was held (provided that
        such Duracell stockholder as a capital asset at the Effective Time).

            4.  No gain or loss will be recognized by Duracell, Gillette or
        Merger Sub as a result of the Merger.

        Re:     Joint Proxy Statement of The Gillette Company and Duracell
                International Inc. ---- Prospectus of The Gillette Company
                ----------------------------------------------------------

Ladies and Gentlemen:

        We have acted as counsel to Duracell International Inc. ("Duracell") in
connection with the Registration Statement on Form S-4 of The Gillette Company
("Gillette") to which this opinion appears as an exhibit (the "Registration
Statement"), which includes the Joint Proxy Statement of Gillette and Duracell
and Prospectus of Gillette (the "Proxy Statement/Prospectus"). Unless otherwise
indicated, any defined term used herein shall have the same meaning as in the
Proxy Statement/Prospectus.

        We hereby confirm that, in our opinion, the following is an accurate
description of the material United States Federal income tax consequences of
the Merger, assuming the due receipt and accuracy of representations as
described under the heading "The Merger -- Certain United States Federal Income
Tax Consequences" in the Proxy Statement/Prospectus:

        1.  No gain or loss will be recognized by a Duracell stockholder upon
the exchange of his or her Duracell Common Stock for Gillette Common Stock,
except that a Duracell stockholder who receives cash proceeds in lieu of a
fractional share interest in Gillette Common Stock will recognize gain or loss
equal to the difference between such proceeds and the tax basis allocated to
the fractional share interest. Such gain or loss will constitute capital gain
or loss if such stockholder's Duracell Common Stock is held as a capital asset
at the Effective Time and will be long-term capital gain or loss if such
stockholder's Duracell Common Stock has been held for more than one year at the
Effective Time.

Duracell International, Inc.            -2-             November 22, 1996


        2.  The tax basis of the Gillette Common Stock received by a Duracell
stockholder will be same as such stockholder's tax basis in the Duracell Common
Stock surrendered in exchange therefor, decreased by the tax basis allocated to
any fractional share interest exchanged for cash.

        3.  The holding period of the Gillette Common Stock received by a
Duracell stockholder will include the period during which the Duracell Common
Stock surrendered in exchange therefor was held (provided that such Duracell
Common Stock was held by such Duracell stockholder as a capital asset at the
Effective Time).

        4.  No gain or loss will be recognized by Duracell, Gillette or Merger
Sub as a result of the Merger.

        We hereby consent to the filing with the Securities and Exchange
Commission of this opinion as an exhibit to the Registration Statement and to
the use of our name in the section entitled "The Merger -- Certain United 
States Federal Income Tax Consequences" of the Proxy Statement/Prospectus. 

        We are members of the Bar of the State of New York, and we do not
express any opinion herein concerning any law other than the federal law of the
United States.
