     This Post-Effective Amendment No. 2 amends the Registration Statement on
Form S-3 (Registration Number 33-30570) of Berkshire Hathaway Inc. ("Berkshire")
originally filed with the Securities and Exchange Commission on August 17, 1989
(the "Registration Statement"). The Registration Statement was declared
effective by the Commission on August 30, 1989. Post-Effective Amendment No. 1
was filed with the Commission on November 8, 1996.
    
 
     This Amendment updates the text of the base prospectus included in the
Registration Statement to reflect more current information regarding Berkshire
and clarifies the text of the base prospectus to state expressly that the
securities registered by the Registration Statement may include Debt Securities
issued by Berkshire which would be exchangeable in certain circumstances into
securities issued by another company.
 
     This Amendment also includes a prospectus supplement to the base
prospectus. The prospectus supplement describes an offering of Debt Securities
exchangeable in certain circumstances into common stock issued by Salomon Inc.

BERKSHIRE HATHAWAY INC.
   % SENIOR EXCHANGEABLE NOTES DUE               , 2001
(SUBJECT TO EXCHANGE INTO SHARES OF COMMON STOCK, PAR VALUE $1.00 PER SHARE, OF
SALOMON INC)
 
The Notes are being offered by Berkshire Hathaway Inc. ("Berkshire") at a price
of $       per $1,000 principal amount due at maturity (the "Issue Price").
Interest on the Notes at the rate of   % per annum on the principal amount due
at maturity is payable semiannually on         and         of each year,
commencing         , 1997. Such rate of interest and accrual of OID (as defined
below) represents a yield to maturity of    % per annum (computed on a semi-
annual bond equivalent basis). "OID" means original issue discount calculated on
a constant yield basis using the $1,000 principal amount due at maturity. The
calculation of original issue discount for United States Federal income tax
purposes will differ. The Notes will be issued with Tax OID (as defined herein)
for U.S. Federal income tax purposes, which will be calculated under recently
issued U.S. Treasury regulations governing contingent payment debt instruments.
For a discussion of certain United States Federal income tax consequences for
holders of Notes, see "Certain United States Federal Income Tax Considerations."
 
   
At maturity (including as a result of acceleration or otherwise), if both (1)
the 10-Day Average Closing Price (as defined herein) of the common stock, par
value $1.00 per share (the "Salomon Common Stock"), of Salomon Inc, a Delaware
corporation ("Salomon"), and (2) the Closing Price (as defined herein) of
Salomon Common Stock on the last trading day (as defined herein) prior to
maturity are equal to or greater than the Exchange Price (as defined herein)
then in effect, each Note will be exchanged by Berkshire into Salomon Common
Stock at an exchange rate (the "Exchange Rate") of    shares of Salomon Common
Stock per Note or, at Berkshire's option, cash equal to the product of the
Exchange Rate and the Current Market Value (as defined herein) of Salomon Common
Stock. In all other circumstances, Berkshire will pay at maturity $1,000 per
Note (or, in the event the Notes mature prior to        , 2001, the Accreted
Value (as defined herein) thereof). Accrued and unpaid interest to maturity will
be payable by Berkshire in cash on all Notes outstanding at maturity. The
Exchange Rate will be subject to adjustment upon the occurrence of certain
events affecting the Salomon Common Stock.
    
 
On the last trading day of January, April, July and October, from and including
January 1997 through and including July 2001 (each, an "Exchange Date"), any
Notes (other than Notes with respect to which a notice of exchange for Salomon
Common Stock has been delivered by Berkshire) will be exchangeable, at the
option of the holder, for shares of Salomon Common Stock at the Exchange Rate
then in effect, provided that the Closing Price of Salomon Common Stock on the
Exchange Date exceeds the Exchange Price then in effect, and subject to certain
additional conditions. In addition, if a prospectus is required to be delivered
under the Securities Act and is not available to Berkshire for use during any
Exchange Period (as defined herein), the foregoing exchange rights will be
subject to cancellation or postponement as described under "Description of the
Notes -- Exchange at Option of Holder."
 
The Notes will not be redeemable or exchangeable at the option of Berkshire
prior to         , 1999. Thereafter, (1) at any time when both (A) the 10-Day
Average Closing Price of Salomon Common Stock on the date on which the
applicable notice of redemption is given and (B) the Closing Price of Salomon
Common Stock on the last trading day prior to such date are equal to or greater
than the Exchange Price then in effect, Berkshire may, at its option, either (i)
exchange the Notes, in whole or in part, for shares of Salomon Common Stock at
the Exchange Rate then in effect or (ii) redeem the Notes, in whole or in part,
in cash at a price per Note equal to the product of the Exchange Rate then in
effect and the Current Market Value of Salomon Common Stock on the date on which
the applicable notice of redemption is given, and (2) at any other time,
Berkshire may, at its option, redeem the Notes, in whole or in part, in cash at
a price per Note equal to the Accreted Value of the Notes on the date of
redemption. Berkshire may not redeem the Notes for cash during certain periods
as described under "Description of the Notes -- Redemption or Exchange at Option
of Berkshire."
 
The Notes are not subject to any sinking fund prior to maturity.
 
Attached hereto as Appendix A is a prospectus supplement and prospectus of
Salomon (the "Salomon Prospectus") covering the shares of Salomon Common Stock
which may be received by a holder of Notes at maturity or upon exchange prior to
maturity.
 
   
The Salomon Common Stock is listed on the New York Stock Exchange (the "NYSE")

NYSE.

                             trading days immediately prior to such date).
    
 
EXCHANGE AT OPTION OF THE
  HOLDER...................  On the last trading day of each January, April,
                             July and October, from and including January 1997
                             through and including July 2001 (each an "Exchange
                             Date"), any Notes (other than Notes with respect to
                             which a notice of exchange for Salomon Common Stock
                             has been delivered by Berkshire prior to such
                             Exchange Date) will be exchangeable, at the option
                             of the holder, for shares of Salomon Common Stock
                             at the Exchange Rate then in effect, provided that
                             (1) such holder has delivered such Notes to the
                             Trustee during the Exchange Period (as defined
                             below) in accordance with the procedures set forth
                             in the Indenture and (2) the Closing Price of
                             Salomon Common Stock on the Exchange Date exceeds
                             the Exchange Price then in effect, and subject to
                             certain additional conditions. In addition, if a
                             prospectus is required to be delivered under the
                             Securities Act and is not available to Berkshire
                             for use during any Exchange Period, the foregoing
                             exchange rights will be subject to cancellation or
                             postponement as described under "Description of the
                             Notes -- Exchange at Option of Holder." The
                             "Exchange Period" with respect to any Exchange Date
                             means the period from the opening of business on
                             the business day immediately prior to such Exchange
                             Date until the close of business on such Exchange
                             Date.
 
REDEMPTION OR EXCHANGE AT
  OPTION OF BERKSHIRE......  The Notes will not be redeemable or exchangeable at
                             the option of Berkshire prior to             ,
                             1999. Thereafter, (1) at any time when both (A) the
                             10-Day Average Closing Price of Salomon Common
                             Stock on the date on which the applicable notice of
                             redemption is given and (B) the Closing Price of
                             Salomon Common Stock on the last trading day prior
                             to such date are equal to or greater than the
                             Exchange Price then in effect, Berkshire may, at
                             its option, either (i) exchange the Notes, in whole
                             or in part, for shares of Salomon Common Stock at
                             the Exchange Rate then in effect or (ii) redeem the
                             Notes, in whole or in part, in cash at a price per
                             Note equal to the product of the Exchange Rate then
                             in effect and the Current Market Value of Salomon
                             Common Stock on the date on which the applicable
                             notice of redemption is given, and (2) at any other
                             time, Berkshire may, at its option, redeem the
                             Notes, in whole or in part, in cash at a price per
                             Note equal to the Accreted Value of the Notes on
                             the date of redemption. However, Berkshire may not
                             give any notice of redemption for cash prior to or
                             during any Exchange Period if the redemption date
                             would occur during or after such Exchange Period.
 
SINKING FUND...............  None.
 
   
RANKING....................  The Notes will be unsecured obligations of
                             Berkshire ranking on a parity with all other
                             unsecured and unsubordinated indebtedness of
                             Berkshire. "Unsubordinated" indebtedness refers to
                             debt obligations of Berkshire that are not
                             specifically by their terms subordinated or junior
                             in rank to other, more senior, debt obligations of
                             Berkshire. Berkshire is a holding company that
                             conducts virtually all of its
    
 
                                       S-4
<PAGE>   7
 
                             operations through subsidiaries and, therefore, the
                             Notes will effectively be subordinated to
                             indebtedness and other liabilities of Berkshire's
                             subsidiaries. As of September 30, 1996, Berkshire's
                             subsidiaries had approximately $16.8 billion of
                             total indebtedness and other liabilities, while
                             Berkshire had no secured indebtedness. The
                             Indenture does not limit the ability of Berkshire
                             or its subsidiaries to incur additional
                             indebtedness (including secured indebtedness).
 
CERTAIN UNITED STATES
  FEDERAL INCOME TAX
  CONSIDERATIONS...........  Because the Notes will be treated as contingent
                             payment debt obligations of Berkshire, and because
                             by accepting Notes holders thereof agree to this
                             treatment of the Notes, U.S. Holders (as defined
                             herein) of the Notes will be required to include
                             original issue discount for United States federal
                             income tax purposes ("Tax OID") in gross income on
                             a constant yield basis over the term of the Notes.
                             The amount of Tax OID will equal the excess of (i)
                             the sum of the cash interest payable over the life
                             of the Notes and an assumed amount payable at
                             maturity of the Notes over (ii) the Issue Price of
                             the Notes. Such Tax OID will be includible in a
                             U.S. Holder's gross income for United States
                             federal income tax purposes (as ordinary income)
                             over the life of the Notes, regardless of when (or
                             whether) cash (or Salomon Common Stock)
                             attributable to such Tax OID is actually received
                             by such holder. The amount of Tax OID includible in
                             a U.S. Holder's gross income during any period will
                             exceed the cash interest payable with respect to a
                             Note for such period. Furthermore, because the
                             amount of Tax OID is calculated based (in part) on
                             an assumed amount payable at maturity, if the value
                             of the Salomon Common Stock or cash actually paid
                             at maturity is, in fact, less than the assumed
                             amount payable at maturity, a U.S. Holder will have
                             recognized taxable income in periods prior to
                             maturity that exceed such holder's economic income
                             from the holding of the Note during such periods
                             (with an offsetting ordinary loss at maturity of
                             the Note). If a U.S. Holder receives shares of
                             Salomon Common Stock (or the cash equivalent
                             thereof) upon a retirement, redemption or optional
                             exchange of a Note, such holder will recognize
                             ordinary taxable income to the extent the value of
                             such Salomon Common Stock (or cash equivalent)
                             exceeds the assumed amount payable at maturity that
                             was taken into account in determining the amount of
                             Tax OID with respect to the Note. A U.S. Holder
                             will also be required to treat any gain recognized
                             upon a sale of a Note as ordinary income (rather
                             than capital gain). See "Certain United States
                             Federal Income Tax Considerations."
 
USE OF PROCEEDS............  The net proceeds received from the sale of Notes
                             will be used for general corporate purposes.
 
   
LISTING....................  An application has been filed to list the Notes on
                             the NYSE. The Salomon Common Stock is currently
                             listed on the NYSE under the symbol "SB."

                       RISK FACTORS RELATING TO THE NOTES
 
     As described in more detail below, the trading price of the Notes may vary
considerably prior to maturity due to, among other things, fluctuations in the
price of Salomon Common Stock and other events that are difficult to predict and
beyond Berkshire's control.
 
COMPARISON TO OTHER DEBT SECURITIES
 
     The terms of the Notes differ from those of ordinary debt securities in
that the amount that a holder of the Notes will receive at maturity or upon
redemption or exchange of the Notes prior to maturity is not fixed, but may be
based on the price of the Salomon Common Stock as described under "Description
of the Notes." Berkshire will not have the right to exchange the Notes for
Salomon Common Stock at or prior to maturity unless both (1) the 10-Day Average
Closing Price of Salomon Common Stock at maturity or on the date on which the
applicable notice of redemption is given and (2) the Closing Price of Salomon
Common Stock on the last trading day prior to such date are equal to or greater
than the Exchange Price then in effect. Therefore, the value (based on such
average and last-day Closing Prices) of the shares of Salomon Common Stock (or
the equivalent cash amount) received by a holder of Notes at maturity will not
be less than the principal amount due at maturity of the Notes. However, the
value of the shares of Salomon Common Stock received by a holder upon exchange
of the Notes at Berkshire's option prior to maturity may fluctuate during the 15
to 30 day period between the date on which the applicable notice of exchange is
given and the effective date of such exchange and, therefore, the value of such
shares on such effective date may be less than the Accreted Value of the Notes
on such date. In addition, the amount of cash received upon any redemption of
the Notes at Berkshire's option prior to maturity will be determined as of the
date on which the applicable notice of redemption is given and, therefore, such
cash amount may be less than the value (determined as of the redemption date) of
the shares of Salomon Common Stock into which such Notes are exchangeable.
 
     In addition, the opportunity for equity appreciation afforded by an
investment in the Notes is less than the opportunity for equity appreciation
afforded by an investment in the Salomon Common Stock because the amount
receivable by a holder of Notes upon redemption or exchange of the Notes at or
prior to maturity will exceed the Accreted Value of such Notes only if both (1)
the 10-Day Average Closing Price of Salomon Common Stock at maturity or on the
date on which the applicable notice of redemption is given and (2) the Closing
Price of Salomon Common Stock on the last trading day prior such date are equal
to or greater than the Exchange Price then in effect. The Exchange Price
initially represents an appreciation of approximately   % over the Closing Price
of the Salomon Common Stock on the NYSE on November   , 1996.
 
RELATIONSHIP OF THE NOTES AND SALOMON COMMON STOCK
 
     The market price of the Notes at any time may be affected by changes in the
price of Salomon Common Stock. Berkshire is making no prediction to prospective
holders of Notes as to whether the price of Salomon Common Stock will rise or
fall. Trading prices of Salomon Common Stock will be determined by Salomon's
operational results and by complex and interrelated economic, financial,
political and other factors that can affect the capital markets generally, the
NYSE (on which the Salomon Common Stock is traded) and the market segment of
which Salomon is a part.
 
     Holders of the Notes will not be entitled to any rights with respect to
Salomon Common Stock (including, without limitation, voting rights and rights to
receive any dividends or other distributions in respect thereof) until such
time, if any, as such Notes have been exchanged at or prior to maturity for
shares of Salomon Common Stock and the applicable record date, if any, for the
exercise of such rights occurs after such date.
 
IMPACT OF THE NOTES ON THE MARKET FOR THE SALOMON COMMON STOCK
 
     It is not possible to predict accurately how or whether the Notes will
trade in the secondary market or whether such market will be liquid. Any market
that develops for the Notes is likely to influence and be
 
                                       S-6
<PAGE>   9
 
influenced by the market for the Salomon Common Stock. For example, the price of
the Salomon Common Stock could become more volatile and could be depressed by
investors' anticipation of the potential distribution into the market of
substantial additional amounts of Salomon Common Stock at the maturity of the
Notes, by possible sales of Salomon Common Stock by investors who view the Notes
as a more attractive means of equity participation in Salomon and by hedging or
arbitrage trading activity that may develop involving the Notes and the Salomon
Common Stock.
 
DILUTION OF SALOMON COMMON STOCK
 
     The Exchange Rate (which determines the number of shares of Salomon Common
Stock that holders of the Notes are entitled to receive upon the exchange at or
prior to maturity) or the exchange consideration is subject to adjustment for
certain events arising from, among others, a merger or consolidation in which
Salomon is not the surviving or resulting corporation, a sale or other transfer
of all or substantially all of the assets of Salomon and the liquidation,
dissolution, winding up or bankruptcy of Salomon, as well as stock splits and
combinations, stock dividends and certain other actions of Salomon that modify
its capital structure. See "Description of the Notes -- Adjustment of Exchange
Rate." The Exchange Rate or the exchange consideration may not be adjusted for
other events, such as offerings of Salomon Common Stock for cash or in
connection with acquisitions, that may adversely affect the price of Salomon
Common Stock and, because of the relationship between the Notes and the price of
Salomon Common Stock, such other events may adversely affect the trading price
of the Notes. There can be no assurance that Salomon or Berkshire will not make
offerings of Salomon Common Stock or take such other action in the future or as
to the amount of such offerings, if any. See "Relationship Between Berkshire and
Salomon."
 
NO OBLIGATION ON PART OF SALOMON WITH RESPECT TO THE NOTES
 
     Other than its obligation to make available a Salomon Prospectus for use by
Berkshire in connection with any exchange of Notes at the option of the holder
as described under "Description of the Notes -- Exchange at Option of Holder,"
Salomon has no obligations with respect to the Notes, including any obligation
to take the needs of Berkshire as issuer of the Notes or of holders of the Notes
into consideration for any reason. Salomon will not receive any of the proceeds
of the offering of the Notes, other than the portion of the Underwriting
Discount earned by Salomon Brothers Inc, a wholly owned subsidiary of Salomon,
in connection with the underwriting of the Notes. Salomon will not be involved
with the administration of the Notes and will have no obligations with respect
to the election of consideration received by holders of the Notes at maturity or
upon redemption or exchange prior to maturity.
 
POSSIBLE ILLIQUIDITY OF THE SECONDARY MARKET
 
   
     The Notes are novel securities and there is currently no secondary market
for the Notes. The Underwriters (other than Salomon Brothers Inc) currently
intend, but are not obligated, to make a market in the Notes. See "Plan of
Distribution." There can be no assurance that a secondary market will develop
or, if a secondary market does develop, that it will provide the holders of the
Notes with liquidity of investment or that it will continue for the life of the
Notes.
    
 
     An application will be filed to list the Notes on the NYSE. However, there
can be no assurance that, if so listed, the Notes will not later be delisted or
that trading in the Notes on the NYSE will not be suspended. In the event of a
failure to list, delisting or suspension of trading on such market, Berkshire
will apply for quotation on another trading market or for listing of the Notes
on another national securities exchange. If the Notes are not listed or traded
on any securities exchange or trading market, or if trading of the Notes is
suspended, pricing information for the Notes may be difficult to obtain, and the
liquidity of the Notes may be adversely affected.
 
TAX CONSEQUENCES
 
     Because the Notes will be treated as contingent payment debt obligations of
Berkshire, and because by accepting Notes holders thereof agree to this
treatment of the Notes, U.S. Holders of the Notes will be
 
                                       S-7
<PAGE>   10
 
required to include original issue discount for U.S. Federal income tax purposes
("Tax OID") in gross income on a constant yield basis over the term of the
Notes. The amount of Tax OID will equal the excess of (i) the sum of the cash
interest payable over the life of the Notes and an assumed amount payable at
maturity of the Notes over (ii) the Issue Price of the Notes. Such Tax OID will
be includible in a U.S. Holder's gross income for U.S. Federal income tax
purposes (as ordinary income) over the life of the Notes, regardless of when (or
whether) cash (or Salomon Common Stock) attributable to such Tax OID is actually
received by such holder. The amount of Tax OID includible in a U.S. Holder's
gross income during any period will exceed the cash interest payable with
respect to a Note for such period. Furthermore, because the amount of Tax OID is
calculated based (in part) on an assumed amount payable at maturity, if the
value of the Salomon Common Stock or cash actually paid at maturity is, in fact,
less than the assumed amount payable at maturity, a U.S. Holder will have
recognized taxable income in periods prior to maturity that exceed such holder's
economic income from the holding of a Note during such periods (with an
offsetting ordinary loss at maturity of the Note). If a U.S. Holder receives
shares of Salomon Common Stock (or the cash equivalent thereof) upon a
retirement, redemption or optional exchange by the holder of a Note, such holder
will recognize ordinary taxable income to the extent the value of such Salomon
Common Stock (or cash equivalent) exceeds the assumed amount payable at maturity
that was taken into account in determining the amount of Tax OID with respect to
the Note. A U.S. Holder will also be required to treat any gain recognized upon
a sale of a Note as ordinary income (rather than capital gain). See "Certain
United States Federal Income Tax Considerations."
 
                                  SALOMON INC
 
   
     Salomon Inc conducts global investment banking, global securities and
commodities trading, and U.S. oil refining and gathering activities. Investment
banking activities are conducted by Salomon Brothers Holding Company Inc and its
subsidiaries, including Salomon Brothers Inc ("Salomon Brothers"). Salomon
Brothers provides capital raising, advisory, trading and risk management
services to its customers, and executes proprietary trading strategies on its
own behalf. Salomon Inc's commodities trading activities are conducted by its
wholly owned subsidiary, Phibro Inc., and its subsidiaries. Oil refining and
gathering activities are conducted by Basis Petroleum, Inc. At November 8, 1996,
Salomon employed 8,639 people.
    
 
   
     Attached hereto as Appendix A is the Salomon Prospectus covering the shares
of Salomon Common Stock offered in connection with the Notes. Information about
reports, proxy statements and other information concerning Salomon filed with
the Securities and Exchange Commission and the NYSE is contained on page 2 of
the Salomon Prospectus.
    
 
                   RELATIONSHIP BETWEEN BERKSHIRE AND SALOMON
 
     As of the date of this Prospectus Supplement, Berkshire beneficially owns
21,370,437 shares of Salomon Common Stock, representing approximately 18% of the
outstanding voting power of Salomon. Such beneficial ownership consists of (1)
10,317,806 shares of Salomon Common Stock held by subsidiaries of Berkshire and
(2) 420,000 shares of the 9.00% Series A Cumulative Convertible Preferred Stock
of Salomon ("Salomon Convertible Preferred Stock") held by subsidiaries of
Berkshire, which shares are convertible, at the option of the holder, into an
aggregate of 11,052,631 shares of Salomon Common Stock at the current conversion
rate.
 
     In October 1987, pursuant to a Purchase Agreement dated September 27, 1987,
between Salomon and Berkshire (the "Purchase Agreement"), Salomon issued to
certain affiliates of Berkshire an aggregate of 700,000 shares of Salomon
Convertible Preferred Stock. In the Purchase Agreement, Berkshire (which for
purposes of the Purchase Agreement includes the affiliates of Berkshire) agreed
that (1) Berkshire will not sell any Salomon securities owned by it to a third
party without first giving Salomon or its designee a reasonable opportunity to
purchase such securities at the same price and on the same terms and conditions
proposed with respect to an anticipated sale by Berkshire to a third party, and
(2) if Salomon does not exercise its right of first refusal and buy Salomon
securities which Berkshire
 
                                       S-8
<PAGE>   11
 
proposes to sell, Berkshire will not knowingly sell to any one entity or group
acting in concert Salomon securities giving such entity or group securities
which amount in the aggregate to over 5% of the Salomon voting stock outstanding
at the time of the sale. In the Purchase Agreement, Salomon agreed to use its
best efforts to nominate and elect Warren E. Buffett and Charles T. Munger, or
two other Berkshire representatives reasonably acceptable to Salomon, to
Salomon's Board of Directors, so long as Berkshire owns at least 5% of Salomon's
outstanding voting securities.
 
     On October 31, 1995, pursuant to the terms of the Certificate of
Designation of the Salomon Convertible Preferred Stock, Salomon redeemed 140,000
shares of Salomon Convertible Preferred Stock for a redemption price of
$140,000,000. On October 29, 1996, Berkshire converted the 140,000 shares of
Salomon Convertible Preferred Stock that would otherwise have been redeemed by
Salomon on October 31, 1996, into 3,684,206 shares of Salomon Common Stock. If
the shares called for redemption are not previously converted, one-third of the
remaining 420,000 shares of Salomon Convertible Preferred Stock are to be
redeemed annually on each October 31 of 1997 through 1999 at $1,000 per share
plus any accrued but unpaid dividends. No cash dividends may be paid on the
Salomon Common Stock, nor may Salomon repurchase any Salomon Common Stock, if
dividends or required redemptions of the Salomon Convertible Preferred Stock are
in arrears.
 
     Berkshire has asked Salomon, pursuant to Salomon's obligations under the
Purchase Agreement, to file a registration statement under the Securities Act
registering the shares of Salomon Common Stock that may be delivered upon
exchange of the Notes. Pursuant to the Purchase Agreement, Salomon will pay
certain expenses arising in connection with such registration. In addition,
Salomon will waive its right of first refusal under the Purchase Agreement with
respect to the delivery of shares of Salomon Common Stock in exchange for the
Notes.
 
     Berkshire has also advised Salomon that, depending upon its evaluation of
market conditions and investment alternatives, Berkshire may effect other types
of transactions that could result in a disposition of a portion of its shares of
Salomon Common Stock, or may determine not to effect any such transaction.
Berkshire expects to remain a large shareholder of Salomon even if, over time,
it disposes of a portion of its shares of Salomon Common Stock. In that
connection, Berkshire has advised Salomon that Mr. Buffett, Berkshire's Chairman
and Chief Executive Officer, and Mr. Munger, its Vice Chairman, expect to remain
on Salomon's Board of Directors, with Mr. Buffett continuing to serve as
Chairman of the Executive Committee. In addition, Louis A. Simpson, President
and Chief Executive Officer--Capital Operations of GEICO Corporation, a wholly
owned subsidiary of Berkshire, would expect to remain a director of Salomon and
to continue serving as Chairman of the Audit Committee.

     Berkshire makes no representation as to the amount of dividends, if any,
that Salomon will pay in the future. In any event, holders of the Notes will not
be entitled to receive any dividends that may be payable on Salomon Common Stock
until such time, if any, as the Notes shall have been exchanged for shares of
Salomon Common Stock and a record date, if any, for such dividend occurs after
such date. See "Description of the Notes."
 
                                USE OF PROCEEDS

               SELECTED CONSOLIDATED FINANCIAL DATA OF BERKSHIRE
 
   
     The selected consolidated financial data which follows should be read in
conjunction with the restated audited consolidated financial statements and
accompanying notes and the unaudited condensed consolidated financial statements
and accompanying notes of Berkshire in the documents which are incorporated by
reference into the Prospectus of Berkshire attached hereto. Berkshire's
consolidated financial statements for the years ended December 31, 1991 through
December 31, 1995 and the nine months ended September 30, 1995 have been
restated to account for Berkshire's acquisition of GEICO Corporation on January
2, 1996. The condensed consolidated financial statements of Berkshire as of
September 30, 1996 and September 30, 1995 and for the nine months ended
September 30, 1996 and September 30, 1995 are unaudited; however, in Berkshire's
opinion, they reflect all adjustments, consisting only of normal recurring
items, necessary for a fair presentation of the financial position and results
of operations for such periods. See "Available Information" and "Incorporation
of Certain Documents by Reference" in the Prospectus.

    businesses, consist of interest on all indebtedness, amortization of debt
    issuance costs and discount or premium relating to any indebtedness, and
    such portion of rental charges considered to be representative of the
    interest component in the particular case. Including fixed charges of
    finance businesses, which consist of interest on indebtedness and, in years

                            DESCRIPTION OF THE NOTES
 
     The following description of the particular terms of the Notes supplements,
and to the extent inconsistent therewith replaces, the description of the
general terms and provisions of the Debt Securities set forth in the
accompanying Prospectus under the "Description of Debt Securities" to which
reference is hereby made.
 
GENERAL
 
     The Notes are to be issued under an indenture dated as of December 1, 1987
(as supplemented from time to time, the "Indenture"), between Berkshire and
State Street Bank and Trust Company, as trustee (the "Trustee"). A copy of the
Indenture has been filed as an exhibit to the Registration Statement of which
this Prospectus Supplement is a part. The following summaries of certain
provisions of the Indenture do not purport to be complete and are subject to,
and are qualified in their entirety by reference to, all the provisions of the
Indenture, including the definitions of certain capitalized terms used in this
Prospectus. Capitalized terms used herein and not otherwise defined have the
meanings set forth in the section, "-- Certain Definitions."
 
     The Notes will mature on             , 2001 (the "Maturity Date"). The
Notes will be limited to $350,000,000 aggregate principal amount due at maturity
($400,000,000 in aggregate principal amount due at maturity if the Underwriters'
over-allotment option is exercised in full), and will be issued in registered
form without coupons in denominations of $1,000 and any integral multiple
thereof. Unless payment on the Notes is accelerated or the Notes are redeemed or
exchanged or otherwise mature prior to the Maturity Date, the principal amount
due at maturity of each Note is $1,000.
 
     The Notes are being offered at a discount from their principal amount due
at maturity. In addition, the Notes will be issued with Tax OID for U.S. Federal
income tax purposes, which will be calculated under recently issued U.S.
Treasury regulations governing contingent payment debt instruments. See "Certain
United States Federal Income Tax Considerations." The Notes will bear interest
at the rate of      % per annum on the principal amount due at maturity (or
     % on the Issue Price), from             , 1996, or from the most recent
date to which interest has been paid or provided for, payable semiannually on
          and           of each year (each an "Interest Payment Date"),
commencing on             , 1997, to holders of record at the close of business
on the           or           immediately preceding each Interest Payment Date.
The maturity (including as a result of acceleration or otherwise), redemption or
exchange of the Notes will cause OID and interest to cease to accrue thereon,
under the terms and subject to the conditions of the Indenture.
 
     Berkshire will maintain an office or agency in New York, New York at which
principal of and interest on the Notes will be paid, Salomon Common Stock (or,
at the option of Berkshire at maturity or in the event of a redemption, its cash
equivalent) will be delivered in any exchange for the Notes at or prior to
maturity upon surrender of such Notes, and the Notes may be presented for
exchange or registration of transfer, except that interest may be paid, at the
option of Berkshire, by check mailed to the registered holders of the Notes.
Such office or agency initially will be at the offices of an affiliate of the
Trustee (and at such other offices or agencies that may be established by
Berkshire for such purposes). The Notes may be transferred, combined or divided
without payment of any charge other than taxes or other governmental charges
involved in issuing Notes in the name of a person other than the holder of the
Note.
 
     No sinking fund is provided for the Notes.
 
PAYMENT OR EXCHANGE AT MATURITY
 
     At maturity (including as a result of acceleration or otherwise), if both
(1) the 10-Day Average Closing Price of Salomon Common Stock and (2) the Closing
Price of Salomon Common Stock on the last trading day prior to maturity are
equal to or greater than the Exchange Price then in effect, each Note will be
exchanged by Berkshire into shares of Salomon Common Stock at the Exchange Rate,
or Berkshire may, at its option, deliver cash, in lieu of delivering shares of
Salomon Common Stock, in an
 
                                      S-14
<PAGE>   17
 
   
amount equal to the product obtained by multiplying the Exchange Rate by the
Current Market Value of Salomon Common Stock at maturity. In all other
circumstances, Berkshire will pay at maturity, in cash, a price per Note equal
to the principal amount due at maturity (or, in the event the Notes mature prior
to the Maturity Date, the Accreted Value thereof). In all events, accrued and
unpaid interest to maturity shall be payable by Berkshire in cash on all Notes
outstanding at maturity. The Exchange Rate or exchange consideration will be
subject to adjustment upon the occurrence of certain events affecting Salomon
Common Stock as described under "-- Adjustment of Exchange Rate."
    
 
   
     In any exchange of Notes for shares of Salomon Common Stock at maturity of
the Notes, no fractional shares of Salomon Common Stock will be issued, as
described under "-- Fractional Shares." Not later than 15 days prior to
maturity, Berkshire will notify The Depository Trust Company and the Trustee and
will publish a notice in a daily newspaper of national circulation stating
whether Berkshire (1) will exchange the Notes for shares of Salomon Common Stock
or (2) will deliver cash equal to the product obtained by multiplying the
Exchange Rate by the Current Market Value of Salomon Common Stock at maturity,
if at maturity both (A) the 10-Day Average Closing Price of Salomon Common Stock
and (B) the Closing Price of Salomon Common Stock on the last trading day prior
to maturity are equal to or greater than the Exchange Price then in effect. The
Salomon Common Stock, if any, to which a holder is entitled upon any exchange at
maturity will be delivered or made available by Berkshire as soon as practicable
and, in any event, not later than the close of business on the fifth Business
Day after maturity. If Berkshire delivers shares of Salomon Common Stock at
maturity of the Notes, holders of the Notes will be responsible for the payment
of any brokerage costs incurred upon any subsequent sale of such stock.
    
 
EXCHANGE AT OPTION OF HOLDER
 
     On the last trading day of each January, April, July and October, from and
including January 1997 through and including July 2001 (each an "Exchange
Date"), any Notes (other than Notes with respect to which a notice of exchange
for Salomon Common Stock has been delivered by Berkshire prior to such Exchange
Date) will be exchangeable, at the option of the holder, for shares of Salomon
Common Stock at the Exchange Rate then in effect, provided that the Closing
Price of Salomon Common Stock on the Exchange Date exceeds the Exchange Price
then in effect, and subject to certain additional conditions described below.
 
   
     To exchange a Note for Salomon Common Stock, a holder must, at any time
during the period from the opening of business on the Business Day immediately
prior to such Exchange Date until the close of business on such Exchange Date
(the "Exchange Period"), (1) deliver to the Trustee (or such other office or
agency that may be established by Berkshire for such purpose) a completed and
manually signed exchange notice (the "Exchange Notice") on the back of such Note
(or a facsimile thereof), (2) surrender or arrange for book entry transfer of
such Note to the Trustee, (3) if required, furnish appropriate endorsements and
transfer documents and (4) if required, pay all transfer or similar taxes. Any
Exchange Notice may be withdrawn by the holder by a written notice of withdrawal
delivered to the Trustee prior to the close of business on the Exchange Date.
The notice of withdrawal shall state the principal amount due at maturity and
any certificate number(s) of the Notes as to which the withdrawal notice relates
and the principal amount due at maturity, if any, which remains subject to the
Exchange Notice, each of which must be $1,000 or an integral multiple thereof.
    
 
     Salomon has agreed with Berkshire to use its reasonable efforts to cause a
shelf registration statement covering the Salomon Common Stock deliverable upon
exchange of the Notes (the "Salomon Registration Statement") to be effective
under the Securities Act during each Exchange Period in order to permit the
Salomon Prospectus forming a part thereof to be usable by Berkshire in
connection with any exchange of Notes at the option of the holder; provided
however, that (1) Salomon may postpone delivery of a prospectus at any time for
valid business reasons, and (2) Salomon's obligation shall cease at such time as
Salomon is no longer an affiliate of Berkshire and a Salomon Prospectus is no
longer required to be delivered under the Securities Act. If a Salomon
Prospectus is required to be delivered and is not made available by Salomon to
Berkshire for use during any Exchange Period, Berkshire shall, on or
 
                                      S-15
<PAGE>   18
 
prior to the applicable Exchange Date, upon written notice to each holder that
has complied with the procedures for exchange of Notes described above (an
"Electing Holder"), postpone such Exchange Date from time to time until such
later Business Day (the "New Exchange Date") as Berkshire is able to deliver a
Salomon Prospectus or is no longer required to do so. In the event that
Berkshire postpones any Exchange Date, (A) no additional Notes may be delivered
to the Trustee by any holder for exchange into Salomon Common Stock at any time
during the period from the original Exchange Date through and including the New
Exchange Date, (B) each Electing Holder shall have the right, at any time until
the New Exchange Date, to irrevocably withdraw any Notes delivered to the
Trustee on or prior to the original Exchange Date, and (C) any Notes that have
not been withdrawn by an Electing Holder prior to the New Exchange Date shall be
exchanged for shares of Salomon Common Stock on the New Exchange Date, provided
that the Closing Price of Salomon Common Stock on the New Exchange Date exceeds
the Exchange Price then in effect.
 
     In addition, if a Reorganization Event shall have occurred as described
under "-- Adjustment of Exchange Rate -- Adjustment of Exchange Consideration
for Consolidation, Merger or Other Reorganization Event," the Notes shall not be
exchangeable at the option of the holder for any Exchange Securities during any
Exchange Period if a prospectus covering such Exchange Securities is required to
be delivered by Berkshire under the Securities Act and is not available to
Berkshire for use during such Exchange Period.
 
     Upon any exchange of Notes at the option of the holder, no payment will be
made in respect of accrued but unpaid interest, unless such exchange is made
concurrently with or after acceleration of the Notes following an event of
default under the Indenture. The Salomon Common Stock to which a holder is
entitled upon any exchange will be delivered or made available by Berkshire as
soon as practicable and, in any event, not later than the close of business on
the fifth Business Day after the applicable Exchange Date.
 
REDEMPTION OR EXCHANGE AT OPTION OF BERKSHIRE
 
     The Notes will not be redeemable or exchangeable at the option of Berkshire
prior to             , 1999. Thereafter, (1) at any time when both (A) the
10-Day Average Closing Price of the Salomon Common Stock on the date on which
the applicable notice of redemption is given and (B) the Closing Price of
Salomon Common Stock on the last trading day prior to such date are equal to or
greater than the Exchange Price then in effect, Berkshire may, at its option,
either (i) exchange the Notes, in whole or in part, for shares of Salomon Common
Stock at the Exchange Rate then in effect or (ii) redeem the Notes, in whole or
in part, in cash at a price per Note equal to the product of the Exchange Rate
then in effect and the Current Market Value of Salomon Common Stock on the date
on which the applicable notice of redemption is given, and (2) at any other
time, Berkshire may, at its option, redeem the Notes, in whole or in part, in
cash at a price per Note equal to the Accreted Value of the Notes on the date of
redemption. However, Berkshire may not give any notice of redemption for cash
(x) during the period from the beginning of any Exchange Period until the close
of business on the applicable Exchange Date or New Exchange Date or (y) prior to
the beginning of any Exchange Period if the redemption date would occur during
or after such Exchange Period. Upon any exchange or redemption described in
clause (1) above, the holders of Notes will not receive any payment representing
accrued OID; such accrued OID will be deemed paid upon the receipt of Salomon
Common Stock or the cash equivalent received on such exchange or redemption.
 
   
     In connection with any redemption or exchange prior to maturity of the
Notes, Berkshire will notify The Depository Trust Company and the Trustee and
will publish a notice in a daily newspaper of national circulation stating (1)
the Exchange Rate then in effect, (2) whether the Notes will be exchanged for
shares of Salomon Common Stock or redeemed for cash, (3) the redemption or
exchange date (which shall be at least 15 days but not more than 30 days after
the date of such notice) and (4) in the case of a redemption, the redemption
price. On the exchange date with respect to any exchange of Notes for Salomon
Common Stock, such Notes shall cease to be outstanding and shall be deemed to
represent solely the right to receive shares of Salomon Common Stock in
accordance with the terms of the
    
 
                                      S-16
<PAGE>   19
 
Indenture. Berkshire will pay in cash the accrued and unpaid interest on all
Notes redeemed or exchanged to but excluding the date of redemption or exchange.
 
     The following table shows the Issue Price, accrued OID, Accreted Value and
Exchange Price of the Notes as of November   , 1999, and at each anniversary
thereof through the Maturity Date. If the Notes are redeemed between any two
such dates, the Accreted Value would include an additional amount reflecting the
additional OID accrued from the previous date in the table, and the Exchange
Price would be adjusted in accordance with the definition of such term.

</TABLE>
 
     In any exchange of Notes for shares of Salomon Common Stock at or prior to
maturity of the Notes, no fractional shares of Salomon Common Stock will be
issued, as described under " -- Fractional Shares." If Berkshire exchanges Notes
for shares of Salomon Common Stock, holders of the Notes will be responsible for
the payment of any brokerage costs incurred upon the subsequent sale of such
shares.
 
     If less than all the Notes then outstanding are to be redeemed or exchanged
prior to maturity of the Notes, the Trustee will select those to be redeemed or
exchanged as a whole or in part pro rata or by lot or by such method as the
Trustee shall deem fair and appropriate. Notice of redemption or exchange will
be given to holders of the Notes to be redeemed or exchanged by first-class
mail, postage prepaid at their last address appearing on the Note registry
books.
 
NO RESTRICTION ON SALE OF SALOMON STOCK
 
   
     The Indenture does not contain any restriction on the ability of Berkshire
to sell, pledge or otherwise convey all or any portion of the Salomon Common
Stock or Salomon Convertible Preferred Stock held by it, and no such shares of
Salomon Common Stock or Salomon Convertible Preferred Stock will be pledged or
otherwise held in escrow for exchange at maturity of the Notes. Consequently, in
the event of a bankruptcy, insolvency or liquidation of Berkshire, the Salomon
Common Stock or Salomon Convertible Preferred Stock, if any, then owned by
Berkshire will be subject to the claims of the creditors of Berkshire. In
addition, as described herein, Berkshire will have the option under certain
circumstances, exercisable in its sole discretion, to satisfy its obligations at
maturity or upon redemption of the Notes by delivering to holders of the Notes
either a number of shares of Salomon Common Stock or cash in an amount equal to
the product obtained by multiplying such number of shares by the Current Market
Value of Salomon Common Stock on the date of the related notice of redemption or
the Maturity Date, as applicable. In the event of a sale, pledge or conveyance
by Berkshire of the Salomon Common Stock or Salomon Convertible Preferred Stock
held by it, a holder of the Notes may be more likely to receive cash in lieu of
Salomon Common Stock in those circumstances in which Berkshire can elect to
deliver either Salomon Common Stock or the cash equivalent. As a result, there
can be no assurance that, if Berkshire can elect at maturity or upon redemption
to deliver Salomon Common Stock, it will do so, or, if it does so elect, that it
will use all or any portion of its current holdings of Salomon Common Stock (or
will convert all or any portion of its current holdings of Salomon Convertible
Preferred Stock into Salomon Common Stock) in order to make such delivery. It is
Berkshire's current intention to deliver Salomon Common Stock at maturity or
exchange of the Notes (if Berkshire has the right to deliver either cash or
Salomon Common Stock at such time); however, Berkshire may change its intention
at any time. Holders of the Notes will not be entitled, as such holders, to any
rights with respect to Salomon Common Stock (including without limitation voting
rights and rights to receive any dividends or other distributions in respect
thereof) until such time, if any, as Berkshire shall have delivered shares of
Salomon Common Stock to holders of the Notes at or prior to maturity in
accordance with the terms of the Indenture. See "Relationship Between Berkshire
and Salomon".

<PAGE>   20
 
RANKING
 
     The Notes will be unsecured obligations of Berkshire ranking on a parity
with all other unsecured and unsubordinated indebtedness of Berkshire. Berkshire
is a holding company that conducts virtually all of its operations through
subsidiaries and, therefore, the Notes will effectively be subordinated to all
indebtedness and liabilities of Berkshire's subsidiaries. As of September 30,
1996, Berkshire's subsidiaries had approximately $16.8 billion of total
indebtedness and other liabilities, while Berkshire had no secured indebtedness.
The Indenture does not limit the ability of Berkshire or its subsidiaries to
incur additional indebtedness (including secured indebtedness).
 
ADJUSTMENT OF EXCHANGE RATE
 
     Adjustment for Distributions, Reclassification, etc. The Exchange Rate
shall be subject to adjustment from time to time as follows:
 
     (1) If Salomon shall:
 
          (A) pay a dividend or make a distribution with respect to the Salomon
     Common Stock in shares of such stock;
 
          (B) subdivide or split the outstanding shares of Salomon Common Stock
     into a greater number of shares;
 
          (C) combine the outstanding shares of Salomon Common Stock into a
     smaller number of shares; or
 
          (D) issue by reclassification of shares of Salomon Common Stock any
     shares of common stock of Salomon;
 
then, in any such event, the Exchange Rate in effect immediately prior to such
event shall be adjusted so that the holder of any Note shall thereafter be
entitled to receive, upon exchange of such holder's Note by Berkshire at
maturity or upon redemption, the number of shares of Salomon Common Stock that
such holder would have owned or been entitled to receive immediately following
such event had such Note been exchanged immediately prior to such event or any
record date with respect thereto. Each such adjustment shall become effective at
the opening of business on the Business Day next following the record date for
determination of holders of Salomon Common Stock entitled to receive such
dividend or distribution in the case of a dividend or distribution and shall
become effective immediately after the effective date in the case of a
subdivision, split, combination or reclassification. Each such adjustment shall
be made successively.
 
     (2) If Salomon shall issue rights or warrants to all holders of Salomon
Common Stock entitling them to subscribe for or purchase shares of Salomon
Common Stock (other than rights to purchase Salomon Common Stock pursuant to (A)
a plan for the reinvestment of dividends or interest or (B) pursuant to a
shareholders rights plan or agreement, unless a triggering event shall have
occurred thereunder) at a price per share less than the current market price of
Salomon Common Stock (determined for purposes of this clause (2) as the Closing
Price per share of Salomon Common Stock on the record date fixed for the
determination of stockholders entitled to receive such rights or warrants), then
in each case the Exchange Rate shall be adjusted by multiplying the Exchange
Rate in effect immediately prior to such record date, by a fraction, of which
(x) the numerator shall be the number of shares of Salomon Common Stock
outstanding at the close of business on such record date, plus the number of
additional shares of Salomon Common Stock offered for subscription or purchase
pursuant to such rights or warrants, and (y) the denominator shall be the number
of shares of Salomon Common Stock outstanding at the close of business on such
record date, plus the number of additional shares of Salomon Common Stock that
the aggregate offering price of the total number of shares of Salomon Common
Stock so offered for subscription or purchase pursuant to such rights or
warrants would purchase at such current market price (calculated at the Closing
Price per share of Salomon Common Stock on such record date), which shall be
determined by multiplying such total numbers of shares offered by the exercise
price of such
 
                                      S-18
<PAGE>   21
 
rights or warrants and dividing the product so obtained by such current market
price. Such adjustment shall become effective at the opening of business on the
Business Day next following the record date for the determination of
stockholders entitled to receive such rights or warrants. To the extent that
shares of Salomon Common Stock are not delivered after the expiration of such
rights or warrants, the Exchange Rate shall be readjusted to the Exchange Rate
which would then be in effect had such adjustments for the issuance of such
rights or warrants been made upon the basis of delivery of only the number of
shares of Salomon Common Stock actually delivered. Each such adjustment shall be
made successively.
 
     (3) If Salomon shall pay a dividend or make a distribution to all holders
of Salomon Common Stock of any class of its capital stock, evidences of its
indebtedness or other assets (in each case excluding any dividends or
distributions referred to in paragraph (1) above or any ordinary periodic cash
dividends that do not constitute Extraordinary Cash Dividends (as defined
below)) or shall issue to all holders of Salomon Common Stock rights or warrants
to subscribe for or purchase any of its securities (other than those referred to
in paragraph (2) above), then in each such case, the Exchange Rate shall be
adjusted by multiplying the Exchange Rate in effect on the record date mentioned
below by a fraction of which (A) the numerator shall be the current market price
per share of the Salomon Common Stock on the record date for the determination
of stockholders entitled to receive such dividend or distribution (such current
market price being determined for purposes of this paragraph as the Closing
Price per share of Salomon Common Stock on such record date) and (B) the
denominator shall be such current market price per share of Salomon Common Stock
less the fair market value (as determined by the Board of Directors of
Berkshire, whose determination shall be conclusive, and described in a
resolution adopted with respect thereto) as of such record date of the portion
of the capital stock, evidences of indebtedness or other assets so distributed
or of such subscription rights or warrants applicable to one share of Salomon
Common Stock; provided, however, that in the event of a distribution of shares
of capital stock of a subsidiary of Salomon (a "Spin-Off") made to holders of
shares of Salomon Common Stock, the numerator of such fraction shall be the sum
of (i) the Closing Price of Salomon Common Stock as of the 35th trading day
after the effective date of such Spin-Off and (ii) the Closing Price of the
number of shares (or the fraction of a share) of capital stock of such
subsidiary of Salomon on such 35th trading day which is distributed in such
Spin-Off in respect of one share of Salomon Common Stock as of such 35th trading
day and the denominator of which shall be the Closing Price of Salomon Common
Stock as of such 35th trading day. Each such adjustment shall become effective
on the opening of business on the Business Day next following the record date
for the determination of stockholders entitled to receive such dividend or
distribution (or, in the case of an adjustment pursuant to the proviso of the
immediately preceding sentence, on the Business Day next following the 35th
trading day after the effective date of the Spin-Off). Each such adjustment
shall be made successively.
 
     Any shares of Salomon Common Stock issuable in payment of a dividend shall
be deemed to have been issued immediately prior to the close of business on the
record date for such dividend for purposes of calculating the number of
outstanding shares of Salomon Common Stock under paragraph (2) above.
 
     All adjustments to the Exchange Rate shall be calculated to the nearest
1/10,000th of a share of Salomon Common Stock (or if there is not a nearest
1/10,000th of a share to the next lower 1/10,000th of a share). No adjustment in
the Exchange Rate shall be required unless such adjustment would require an
increase or decrease of at least one percent therein; provided, however, that
any adjustments which by reason of this paragraph are not required to be made
shall be carried forward and taken into account in any subsequent adjustment.
 
   
     For purposes of the foregoing, the term "Extraordinary Cash Dividend" shall
mean, with respect to any consecutive 365-day period, any cash dividend with
respect to Salomon Common Stock the amount of which, together with the aggregate
amount of all other such cash dividends on the Salomon Common Stock occurring in
such 365-day period, exceeds on a per share basis 10% of the average Closing
Price per share of the Salomon Common Stock over such 365-day period, and for
purposes of applying the formula set forth in paragraph (3) above, the fair
market value of such dividends being calculated pursuant to such paragraph (3)
shall be equal to (A) the aggregate amount of such cash dividend together with
the amounts of such other cash dividends occurring in such period minus (B) the
    
 
                                      S-19
<PAGE>   22
 
aggregate amount of such other cash dividends occurring in such period for which
a prior adjustment in the Exchange Rate was previously made as described in this
subsection. In making the determinations required by the foregoing sentence, the
amount of cash dividends paid on a per share basis shall be appropriately
adjusted to reflect the occurrence during such period of any event described in
this subsection.
 
   
     Adjustment of Exchange Consideration for Consolidation, Merger or Other
Reorganization Event. In the event of (1) any consolidation or merger of
Salomon, or any surviving entity or subsequent surviving entity of Salomon (a
"Salomon Successor"), with or into another entity (other than a merger or
consolidation in which Salomon is the continuing corporation and in which the
Salomon Common Stock outstanding immediately prior to the merger or
consolidation is not exchanged for cash, securities ("Exchange Securities") or
other property of Salomon or another corporation), (2) any statutory exchange of
securities of Salomon or any Salomon Successor with another corporation (other
than in connection with a merger or acquisition) or (3) any liquidation,
dissolution or winding up of Salomon or any Salomon Successor (any such event, a
"Reorganization Event"), if Berkshire shall have the right to deliver either
cash or Salomon Common Stock at maturity or upon redemption or exchange of the
Notes, then, at the option of Berkshire, each holder of Notes will receive at
maturity or upon redemption or exchange, in lieu of Salomon Common Stock, cash
in an amount equal to the Exchange Rate multiplied by the Transaction Value (as
defined herein). Notwithstanding the foregoing, with respect to any securities
received in a Reorganization Event that (A) are (i) listed on a United States
national securities exchange, (ii) reported on a United States national
securities system subject to last sale reporting, (iii) traded in the
over-the-counter market and reported on the National Quotation Bureau or similar
organization or (iv) for which bid and ask prices are available from at least
three nationally recognized investment banking firms and (B) are either (x)
perpetual equity securities or (y) non-perpetual equity or debt securities with
a stated maturity after the Maturity Date ("Reported Exchange Securities"),
Berkshire may, at its option, in lieu of delivering the amount of cash
deliverable in respect of Reported Exchange Securities received in a
Reorganization Event, as determined in accordance with the previous sentence,
deliver a number of such Reported Exchange Securities with a value equal to such
cash amount, as determined in accordance with clause (2) of the definition of
Transaction Value, as applicable; provided, however, that (a) if such option is
exercised, Berkshire shall deliver Reported Exchange Securities in respect of
all, but not less than all, cash amounts that would otherwise be deliverable in
respect of Reported Exchange Securities received in a Reorganization Event, (b)
Berkshire may not exercise such option if Berkshire has elected to deliver cash
in lieu of Salomon Common Stock deliverable at maturity or upon redemption and
(c) Berkshire must exercise such option if Berkshire does not elect to deliver
cash in lieu of Salomon Common Stock deliverable at maturity or upon redemption.
If Berkshire elects to deliver Reported Exchange Securities, each holder of
Notes will be responsible for the payment of any and all brokerage and other
transaction costs upon the sale of such Reported Exchange Securities. If,
following any Reorganization Event, any Reported Exchange Security ceases to
qualify as a Reported Exchange Security, then (x) Berkshire may no longer elect
to deliver such Reported Exchange Security in lieu of an equivalent amount of
cash and (y) notwithstanding clause (2) of the definition of Transaction Value,
the Transaction Value of such Reported Exchange Security shall mean the fair
market value of such Reported Exchange Security on the date such security ceases
to qualify as a Reported Exchange Security, as determined by a nationally
recognized investment banking firm selected for this purpose by Berkshire.
    
 
     If a Reorganization Event shall occur, subject to certain conditions
described under "-- Exchange at Option of Holder," upon exchange of any Notes at
the option of the holder, each holder of a Note will have the right to receive
the kind and amount of cash, Exchange Securities or other property receivable
upon such Reorganization Event by a holder of the number of shares of Salomon
Common Stock for which such Note might have been exchanged immediately prior to
such Reorganization Event (assuming that such holder failed to exercise his
rights of election, if any, as to the kind or amount of cash, Exchange
Securities, and other property receivable in such Reorganization Event).

<PAGE>   23
 
     The kind and amount of securities into which the Notes shall be
exchangeable by Berkshire after consummation of any Reorganization Event shall
be subject to adjustment as described above in "Adjustment of Exchange
Rate -- Adjustment for Distributions, Reclassification, etc." following the date
of consummation of such transaction.
 
     Notice of Adjustments and Certain Other Events. (1) Whenever the Exchange
Rate or the consideration receivable upon exchange is adjusted as previously
described, Berkshire shall:
 
          (A) forthwith compute the adjusted Exchange Rate as described above in
     "Adjustment of Exchange Rate -- Adjustment for Distributions,
     Reclassification, etc." or the adjusted exchange consideration described
     above in "Adjustment of Exchange Rate -- Adjustment of Exchange
     Consideration for Consolidation, Merger or Other Reorganization Event" and
     prepare a certificate signed by an officer of Berkshire setting forth the
     adjusted Exchange Rate or exchange consideration, the method of calculation
     thereof in reasonable detail, and the facts requiring such adjustment and
     upon which such adjustment is based, which certificate shall be conclusive,
     final and binding evidence of the correctness of the adjustment, and file
     such certificate forthwith with the Trustee; and
 
          (B) within 10 Business Days following the occurrence of an event that
     permits or requires an adjustment to the Exchange Rate or exchange
     consideration as described in "Adjustment of Exchange Rate -- Adjustment
     for Distributions, Reclassification, etc." and "Adjustment of Exchange
     Rate -- Adjustment of Exchange Consideration for Consolidation, Merger or
     Other Reorganization Event" (or if Berkshire is not aware of such
     occurrence, as soon as practicable after becoming so aware), provide
     written notice to the Trustee and to the holders of the outstanding Notes
     of the occurrence of such event and a statement in reasonable detail
     setting forth the method by which the adjustment to the Exchange Rate or
     exchange consideration was determined and setting forth the revised
     Exchange Rate or exchange consideration per Note.
 
     (2) In case at any time while any of the Notes are outstanding Berkshire
receives notice that:
 
          (A) Salomon has declared a dividend (or any other distribution) on or
     in respect of the Salomon Common Stock to which clause (1) or (2) of
     "Adjustment of Exchange Rate -- Adjustment for Distributions,
     Reclassification, etc." shall apply (other than any cash dividends and
     distributions, if any, paid from time to time by Salomon that do not
     constitute Extraordinary Cash Dividends);
 
          (B) Salomon has authorized the issuance to all holders of Salomon
     Common Stock of rights or warrants to subscribe for or purchase shares of
     Salomon Common Stock or of any other subscription rights or warrants;
 
          (C) there shall be proposed any conversion or reclassification of
     Salomon Common Stock (other than a subdivision or combination of
     outstanding shares of such Salomon Common Stock) or any consolidation,
     merger or reorganization to which Salomon is a party and for which approval
     of any stockholders of Salomon is required; or
 
          (D) there shall be proposed the voluntary or involuntary dissolution,
     liquidation or winding up of Salomon;
 
then Berkshire shall promptly cause to be delivered to the Trustee and filed at
the office or agency maintained for the purpose of exchange of Notes in the
Borough of Manhattan, in The City of New York by the Trustee, and shall promptly
cause to be mailed to the holders of the Notes at their last addresses as they
shall appear upon the registration books of the Securities Registrar, at least
10 days before the date hereinafter specified (or the earlier of the dates
hereinafter specified, in the event that more than one is specified), a notice
stating (i) the date on which a record is to be taken for the purpose of such
dividend, distribution or grant of rights or warrants, or, if a record is not to
be taken, the date as of which the holders of Salomon Common Stock to be
entitled to such dividend, distribution or grant of rights or
 
                                      S-21
<PAGE>   24
 
warrants are to be determined, or (ii) the date, if known by Berkshire, on which
such reclassification, consolidation, merger, dissolution, liquidation or
winding up is expected to become effective.
 
FRACTIONAL SHARES
 
     No fractional shares of Salomon Common Stock will be issued if any Notes
are exchanged for shares of Salomon Common Stock at or prior to maturity. If
more than one Note from the same holder is exchanged for Salomon Common Stock at
one time, the number of full shares of Salomon Common Stock to be delivered upon
exchange shall be computed on the basis of the aggregate number of Notes from
such holder so exchanged at that time. In lieu of any fractional share otherwise
issuable in respect of all Notes of any holder that are exchanged at or prior to
maturity, such holder shall be entitled to receive an amount in cash equal to
the product of such fraction of a share and the Current Market Value of Salomon
Common Stock on the applicable Exchange Date (in the case of an exchange at the
option of the holder), the date on which the related notice of exchange is given
(in the case of an exchange at the option of Berkshire) or the Maturity Date, as
applicable.
 
BOOK-ENTRY SYSTEM
 
     The Notes will be issued in the form of one or more global securities (the
"Global Securities") deposited with The Depository Trust Company (the
"Depositary") and registered in the name of a nominee of the Depositary.
 
     The Depositary has advised Berkshire and the Underwriters as follows: The
Depositary is a limited purpose trust company organized under the laws of the
State of New York, a member of the Federal Reserve System, a "clearing
corporation" within the meaning of the New York Uniform Commercial Code and a
"clearing agency" registered pursuant to Section 17A of the Exchange Act. The
Depositary was created to hold securities of persons who have accounts with the
Depositary ("participants") and to facilitate the clearance and settlement of
securities transactions among its participants in such securities through
electronic book-entry changes in accounts of the participants, thereby
eliminating the need for physical movement of certificates. Such participants
include securities brokers and dealers, banks, trust companies and clearing
corporations. Indirect access to the Depositary's book-entry system also is
available to others such as banks, brokers, dealers and trust companies that
clear through or maintain a custodial relationship with a participant, either
directly or indirectly.
 
     Upon the issuance of a Global Security, the Depositary or its nominee will
credit the respective Notes represented by such Global Security to the accounts
of participants. The accounts to be credited shall be designated by the
Underwriters. Ownership of beneficial interests in the Global Securities will be
limited to participants or persons that may hold interests through participants.
Ownership of beneficial interests by participants in such Global Securities will
be shown on, and the transfer of those ownership interests will be effected only
through, records maintained by the Depositary or its nominee for such Global
Securities. Ownership of beneficial interests in such Global Securities by
persons that hold through participants will be shown on, and the transfer of
that ownership interest within such participant will be effected only through,
records maintained by such participant. The laws of some jurisdictions require
that certain purchasers of securities take physical delivery of such securities
in definitive form. Such limits and such laws may impair the ability to transfer
beneficial interests in a Global Security.
 
     So long as the Depositary, or its nominee, is the registered owner of a
Global Security, such depositary or such nominee, as the case may be, will be
considered the sole owner or holder of the Notes for all purposes under the
Indenture. Except as set forth below, owners of beneficial interests in such
Global Securities will not be entitled to have the Notes registered in their
names, will not receive or be entitled to receive physical delivery of the Notes
in definitive form and will not be considered the owners or holders thereof
under the Indenture.
 
     Payment of principal of and any interest on the Notes registered in the
name of or held by the Depositary or its nominee will be made to the Depositary
or its nominee, as the case may be, as the registered owner or the holder of the
Global Security. None of Berkshire, the Trustee, any paying agent or
 
                                      S-22
<PAGE>   25
 
any securities registrar for the Notes will have any responsibility or liability
for any aspect of the records relating to or payments made on account of
beneficial ownership interests of a Global Security or for maintaining,
supervising or reviewing any records relating to such beneficial ownership
interests.
 
     Berkshire expects that the Depositary, upon receipt of any payment of
principal or interest in respect of a permanent Global Security, will credit
immediately participants' accounts with payments in amounts proportionate to
their respective beneficial interests in the principal amount of such Global
Security as shown on the records of the Depositary. Berkshire also expects that
payments by participants to owners of beneficial interests in such Global
Security held through such participants will be governed by standing
instructions and customary practices, as is now the case with securities held
for the accounts of customers in bearer form or registered in "street name," and
will be the responsibility of such participants.
 
     A Global Security may not be transferred except as a whole by the
Depositary to a nominee or a successor of the Depositary. If the Depositary is
at any time unwilling or unable to continue as depositary and a successor
depositary is not appointed by Berkshire within ninety days, Berkshire will
issue Notes in definitive registered form in exchange for the Global Security
representing such Notes. In addition, Berkshire may at any time and in its sole
discretion determine not to have any Notes represented by one or more Global
Securities and, in such event, will issue Notes in definitive form in exchange
for all of the Global Securities representing the Notes. Further, if Berkshire
so specifies with respect to the Notes, an owner of a beneficial interest in a
Global Security representing Notes may, on terms acceptable to Berkshire and the
Depositary for such Global Security, receive Notes in definitive form. Moreover,
if there shall have occurred and be continuing an Event of Default, or an event
that, with the giving of notice or lapse of time, or both, would constitute an
Event of Default with respect to any Notes represented by one or more Global
Securities, such Global Securities shall be exchangeable for Notes in definitive
form. In any such instance, an owner of a beneficial interest in a Global
Security will be entitled to physical delivery in definitive form of Notes
represented by such Global Security equal in number to that represented by such
beneficial interest and to have such Notes registered in its name.
 
DEFEASANCE
 
     The provisions in the accompanying Prospectus regarding defeasance of Debt
Securities will not be applicable to the Notes.

            CERTAIN UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS
 
   
     The following discussion is a general summary of the material United States
("U.S.") Federal income tax considerations that may be relevant to a holder of
Notes that is a U.S. Holder (as defined below). This summary is based on
provisions of the U.S. Internal Revenue Code of 1986, as amended (the "Code"),
existing and proposed Treasury regulations promulgated thereunder, and
administrative and judicial interpretations thereof, all as currently in effect
and all of which are subject to change (possibly with retroactive effect) and to
differing interpretations. Furthermore, there can be no assurance that the
Internal Revenue Service would not take a position contrary to those expressed
herein. This summary deals only with U.S. Holders that hold the Notes as capital
assets and does not address all aspects of U.S. Federal income taxation that may
be applicable to investors in light of their particular circumstances, or to
investors subject to special treatment under U.S. Federal income tax law
(including, but not limited to, life insurance companies, dealers in securities,
financial institutions, tax-exempt organizations, persons having a functional
currency other than the U.S. dollar, and persons holding the Notes as a position
in a "straddle" or conversion transaction, or as part of a "synthetic security"
or other integrated financial transaction). This summary also does not address
the state, local or foreign tax consequences of an investment in the Notes.
    
 
   
     As used herein, the term "U.S. Holder" means a holder of a Note that is,
for U.S. Federal income tax purposes, (1) an individual citizen or resident of
the United States, (2) a corporation, or other entity taxable as a corporation
for U.S. Federal income tax purposes, created or organized in or under the laws
of the United States or of any political subdivision thereof, (3) an estate or
trust the income of which is subject to U.S. Federal income taxation regardless
of its source, or (4) a person otherwise subject to U.S. Federal income taxation
on a net basis in respect of such holder's ownership of a Note.
    
 
TAXATION OF THE NOTES
 
   
     Berkshire has received an opinion of Munger, Tolles & Olson, counsel to
Berkshire, that the Notes will be treated as single debt instruments subject to
recently issued U.S. Treasury regulations governing contingent payment debt
instruments (the "Contingent Payment Regulations"). Berkshire intends to treat
each Note as a contingent payment debt instrument subject to the Contingent
Payment Regulations, and by accepting Notes, holders thereof agree to this
treatment and to report all income (or loss) with respect to the Notes in
accordance with those regulations. The Contingent Payment Regulations require
the application of a "noncontingent bond" method to determine accruals of
income, gain, loss and deduction with respect to a contingent debt obligation.
As described in more detail in the second succeeding paragraph, under the
noncontingent bond method, a U.S. Holder of a Note will be required for tax
purposes to include in income each year an accrual of interest at the rate of
     % (the "comparable yield"). Accordingly, for purposes of the Contingent
Payment Regulations, a U.S. Holder of a Note will be assumed to be entitled to
receive, in respect of the Note, semi-annual payments of interest at a rate of
     %, as well as a fixed payment (in stock) of $          on             ,
2001 (the "Payment Schedule"). The fixed payment due on             , 2001 is
calculated as the amount required to produce the comparable yield when combined
with the semi-annual payments of interest made in respect of the Note and taking
into account the Note's Issue Price.
    
 
     The comparable yield and the Payment Schedule are used to determine
accruals of interest for tax purposes only and are not assurances by Berkshire
with respect to the actual yield of, or payments to be made in respect of, the
Note. The comparable yield and the Payment Schedule do not necessarily represent
Berkshire's expectations regarding such yield or the amounts of such payments.
 
     Each Note is being issued at a price of $          per $1,000 principal
amount due at maturity, which represents OID of   % from the principal amount
due at maturity of the Note. The amount of OID on a Note for U.S. Federal income
tax purposes ("Tax OID"), however, will be greater than the amount of OID on the
Note described in the preceding sentence, because the relevant tax rules require
that Tax OID
 
                                      S-25
<PAGE>   28
 
be accrued at the comparable yield, rather than on the stated coupon plus the
OID on the Note. Under the Tax OID rules of the Code, and the Treasury
regulations promulgated thereunder, a U.S. Holder, whether such holder uses the
cash or the accrual method of tax accounting, will be required to include as
ordinary interest income the sum of the "daily portions" of Tax OID on the Note
for all days during the taxable year that the U.S. Holder owns the Note. As a
result, a U.S. Holder of a Note that employs the cash method of accounting will
be required to include amounts in respect of Tax OID accruing on the Note in
taxable income each year, whether or not the current receipt of cash from the
Note is sufficient to pay any resulting tax.
 
     The daily portions of Tax OID on a Note are determined by allocating to
each day in any accrual period a ratable portion of the Tax OID allocable to
that accrual period. In the case of an initial holder, the amount of Tax OID on
a Note allocable to each accrual period is determined by multiplying the
"adjusted issue price" (as defined below) of the Note at the beginning of the
accrual period by the comparable yield of the Note (appropriately adjusted to
reflect the length of the accrual period). The "adjusted issue price" of a Note
at the beginning of any accrual period generally will be the sum of its Issue
Price and the amount of Tax OID allocable to all prior accrual periods, less the
amount of any payments made in all prior accrual periods.
 
     When a U.S. Holder sells, exchanges or otherwise disposes of a Note
(including the repayment of the Note on the Maturity Date or the exercise by
Berkshire or the U.S. Holder of its respective option to exchange the Notes for
Salomon Common Stock) (a "disposition"), the U.S. Holder's gain (or loss) on
such disposition will equal the difference between the amount received by the
U.S. Holder for the Note and the U.S. Holder's tax basis in the Note. Upon the
repayment of a Note on the Maturity Date or on an earlier exercise by Berkshire
or the U.S. Holder of its respective exchange option, the U.S. Holder will be
treated as receiving an amount equal to the fair market value of any Salomon
Common Stock received by such holder, plus any cash received in lieu of
fractional shares. A U.S. Holder's tax basis (i.e., adjusted cost) in a Note
will be equal to the U.S. Holder's original purchase price for the Note, plus
any Tax OID accrued by the U.S. Holder and less the amount of any payments
received by such holder while holding such Note. Any gain realized by a U.S.
Holder on a disposition will be treated as ordinary interest income. Any loss
realized by a U.S. Holder on a disposition will be treated as ordinary loss, to
the extent of the U.S. Holder's Tax OID inclusions with respect to the
obligation up to the date of disposition. Any loss realized in excess of such
amount generally will be treated as a capital loss. An individual U.S. Holder
generally will be allowed a deduction for any such loss without regard to the
two-percent miscellaneous itemized deduction rule of section 67 of the Code. Any
capital loss recognized by a U.S. Holder will be a long-term capital loss if
such U.S. Holder has held such Note for more than one year, and a short-term
capital loss in other cases. If a U.S. Holder receives Salomon Common Stock in a
disposition, such holder will have a basis in that stock equal to the stock's
fair market value on the date of the disposition. Additionally, the U.S.
Holder's holding period in the Salomon Common Stock will begin the day after the
disposition.
 
   
     A U.S. Holder that purchases a Note in the secondary market for an amount
that differs from the Note's adjusted issue price at the time of purchase will
be required to accrue Tax OID on the contingent debt obligation in accordance
with the comparable yield and Payment Schedule, even if market conditions have
changed since the date of issuance. If the difference between a U.S. Holder's
purchase price for the Note and the adjusted issue price of the Note is
attributable to a change in interest rates, the U.S. Holder will be required to
allocate that difference among all remaining Tax OID accruals on the Note. If
the difference between a U.S. Holder's purchase price for the Note and the
adjusted issue price of the Note is attributable to a change in expectations as
to the payment to be made by Berkshire on the Maturity Date, the U.S. Holder
will be required to allocate that difference to the payment on the Maturity
Date. Adjustments allocated to either a Tax OID accrual or the payment on the
Maturity Date are taken into account at the time the corresponding Tax OID is
accrued or payment is made. If the purchaser's basis is greater than the
adjusted issue price of the Note, the excess is treated as a "negative
adjustment" that reduces such Tax OID accruals or payment; if the purchaser's
basis is less than the adjusted issue price, the difference is treated as a
"positive adjustment" that similarly increases such Tax OID accruals or payment.
Any negative and positive adjustments of the kind described above made
    
 
                                      S-26
<PAGE>   29
 
by a U.S. Holder of a Note in respect of any difference between its purchase
price and the adjusted issue price of the Note on the date of purchase decrease
or increase, respectively, the U.S. Holder's basis in the Note, in a manner
consistent with the operation of the general premium and market discount rules
that such adjustments supersede.
 
     Certain U.S. Holders may receive Forms 1099-OID reporting Tax OID accruals
on a Note. Those forms may not, however, reflect the effects of any positive or
negative adjustments resulting from the U.S. Holder's purchase of a Note in the
secondary market at a price that differs from its adjusted issue price on the
date of purchase. U.S. Holders are urged to consult their tax advisors as to
whether, and how, such adjustments should be made to the amounts reported on any
Form 1099-OID.
 
BACKUP WITHHOLDING AND INFORMATION REPORTING
 
     A U.S. Holder may be subject to information reporting and to backup
withholding at a rate of 31 percent with respect to payments made on a Note, or
the proceeds of the sale of a Note before maturity, unless such U.S. Holder
provides proof of an applicable exemption or a correct taxpayer identification
number, and otherwise complies with applicable requirements of the information
reporting and backup withholding rules.
 
TAXATION OF SALOMON COMMON STOCK
 
  Distributions on Salomon Common Stock. The gross amount of any distribution
made by Salomon to a U.S. Holder with respect to the Salomon Common Stock
generally will be includible in the income of a U.S. Holder as dividend income
to the extent that such distribution is paid out of Salomon's current or
accumulated earnings and profits as determined under U.S. Federal income tax
principles. Subject to certain limitations, United States corporations holding
Salomon Common Stock that receive dividends thereon generally will be eligible
for a dividends-received deduction equal to 70% of the dividends received. If
the amount of any distribution exceeds Salomon's current and accumulated
earnings and profits as so computed, such excess first will be treated as a
tax-free return of capital to the extent of the U.S. Holder's tax basis in its
Salomon Stock, and thereafter as gain from the sale or exchange of property.
 
  Dispositions of Salomon Common Stock. A U.S. Holder generally will recognize
capital gain or loss for U.S. Federal income tax purposes on the sale or
disposition of Salomon Common Stock in an amount equal to the difference between
the amount realized on the sale or other disposition and the U.S. Holder's tax
basis in the Salomon Common Stock. Any such gain or loss will be long-term gain
or loss if the U.S. Holder held the Salomon Common Stock for more than one year.
As discussed above, a U.S. Holder that received Salomon Common Stock from
Berkshire in a disposition of a Note will have a basis in that Salomon Common
Stock equal to that stock's fair market value on the date of such disposition of
the Note. Additionally, the U.S. Holder's holding period in the Salomon Common
Stock will begin the day after such disposition of the Note.

     In the Underwriting Agreement, the several Underwriters have agreed,
subject to the terms and conditions set forth therein, to purchase all of the
Notes if any are purchased.
 
     Berkshire has been advised that the Underwriters propose to offer the Notes
to the public initially at the offering price set forth on the cover of this
Prospectus Supplement and to certain dealers at such price less a selling
concession of not more than      % of such principal amount of the Notes; that
the Underwriters may allow, and each such dealer may reallow, to other dealers a
concession not exceeding      % of such principal amount of the Notes; and that
such Issue Price and such concession and reallowance may be changed by the
Underwriters after completion of the offering of the Notes.
 
     Berkshire has granted to the Underwriters an option, exercisable for 30
days from the date of this Prospectus Supplement (or, if such 30th day is not a
Business Day, on the next Business Day thereafter), to purchase up to an
additional $50,000,000 aggregate principal amount of the Notes at the Issue
Price set forth on the cover page hereof, less the underwriting discount. The
Underwriters may exercise such option solely for the purpose of covering
over-allotments, if any, incurred in connection with the sale of the Notes
offered hereby.
 
   
     Each of Berkshire and Salomon has agreed that it will not, for a period of
90 days after the date of this Prospectus Supplement, without the written
consent of Salomon Brothers, offer, sell or contract to sell, or otherwise
dispose of, directly or indirectly, or announce the offering of, any shares of
Salomon Common Stock, or any securities convertible into or exchangeable for,
shares of Salomon Common Stock; provided, however, that such restriction shall
not affect the ability of Berkshire, Salomon or their subsidiaries to take any
such actions in connection with the offer and sale of the Notes or any exchange
at or prior to maturity pursuant to the terms of Notes; and provided, further,
that Salomon may sell or register shares of Salomon Common Stock or grant
options to purchase the same, in either case, pursuant to any employee or
director stock option plan, stock ownership plan or dividend reinvestment plan
of Salomon in effect as of the date of this Prospectus.
    
 
     Berkshire and Salomon have agreed in the Underwriting Agreement to
indemnify the Underwriters and their controlling persons against certain
liabilities under the Securities Act or to contribute to payments the
Underwriters or their controlling persons may be required to make in respect
thereof. Berkshire and Salomon have also agreed to indemnify each other and
their controlling persons with respect to certain liabilities, including
liabilities under the Securities Act, or contribute to payments in respect
thereof.
 
     Berkshire has been advised by the Underwriters (other than Salomon
Brothers) that they may make a market in the Notes but they are not obligated to
do so and may discontinue such market making at any time without notice. No
assurance can be given that an active public market for the Notes will develop.
 
     Salomon Brothers is a wholly owned subsidiary of Salomon. Berkshire
beneficially owns Salomon Common Stock and Salomon Preferred Stock representing
approximately 18% of the voting power of Salomon. Mr. Buffett, Mr. Munger, and
Louis A. Simpson, President and Chief Executive Officer-Capital Operations of
GEICO Corporation, are directors of Salomon. Because of such ownership and other

     In the ordinary course of their respective businesses, certain of the
Underwriters and their respective affiliates have engaged in and may in the
future engage in commercial and investment banking transactions with Berkshire,
Salomon and their affiliates.

     Berkshire is a holding company owning subsidiaries engaged in a number of
diverse business activities. The most important of these is the property and
casualty insurance business, which Berkshire conducts through subsidiaries
referred to collectively as the Berkshire Hathaway Insurance Group. See
"-- Berkshire Hathaway Insurance Group." The investment portfolios of the
insurance subsidiaries include meaningful equity ownership percentages of other
publicly traded companies. See "-- Common Stock Investments." In addition,
Berkshire publishes the Buffalo News, a daily and Sunday newspaper in upstate
New York, and its non-insurance subsidiaries engage in a variety of
manufacturing, publication, retail and finance businesses. See "-- Non-Insurance
Businesses of Berkshire."
 
     Operating decisions for the various insurance and non-insurance businesses
of Berkshire are made by the managers of the business units. Investment
decisions and all other capital allocation decisions are made for Berkshire and
its subsidiaries by Warren E. Buffett, Berkshire's Chairman, in consultation
with Charles T. Munger, its Vice-Chairman.
 
     Berkshire's executive offices are located at 1440 Kiewit Plaza, Omaha,
Nebraska 68131, and its telephone number at that location is (402) 346-1400.
 
  Berkshire Hathaway Insurance Group
 
     The Berkshire Hathaway Insurance Group (the "Group") operates a primary or
direct insurance business nationwide and a reinsurance business worldwide. The
largest subsidiary in the Group is National Indemnity Company ("National
Indemnity"), headquartered in Omaha, Nebraska with offices also in Stamford,
Connecticut. Also included in this Group is GEICO Corporation ("GEICO"), the
seventh largest auto insurer in the United States.
 
     The Group maintains capital strength at high levels, significantly higher
than normal in the industry. This capital strength differentiates Group members
from their competitors. For example, in each of the five years from 1991 through
1995 the Group's ratio of net premiums written to year-end statutory surplus was
10% or less; the addition of GEICO will cause the Group's ratio to increase in
1996 to a presently estimated 15%-20%. The industry average net
premiums-to-surplus ratio from 1991 through 1995 ranged from 113% to 141% (based
on statistics published by A.M Best & Company).
 
     Because it maintains large capital in relation to annual premiums written,
Berkshire can pay losses under the most adverse circumstances. This obvious
margin of safety is very attractive to the Group's insureds, and creates
opportunities for the Group to negotiate and enter into contracts of insurance
specially designed to meet unique needs of sophisticated insurance and
reinsurance buyers. Berkshire's capital base also allows the Group to issue
policies with limits larger than other insurance companies are typically
prepared to write. Finally, large capital combined with low overhead allows the
Group to respond to insurance opportunities with exceptional speed and be
selective about the business it writes. The Group can forbear from writing
policies when it perceives rates to be inadequate. Conversely, it can more fully
utilize its capital strength when better-than-industry-average results may be
expected.
 
     Reinsurance. The Reinsurance Division of National Indemnity, located in
Stamford, Connecticut, provides excess of loss and quota share treaty
reinsurance to other property/casualty insurers and reinsurers. Minimal
organizational resources, but huge financial resources, are currently devoted to
this business.
 
   
     During 1990, management of the Group perceived declines in industry
capacity and competition for megacatastrophe excess-of-loss reinsurance
("super-cat") coverages. Consequently, National Indemnity has written coverages
for a number of such risks. Management believes that in recent years the Group
has been the largest provider in the world of this type of coverage. These
coverages may provide sizeable amounts of indemnification per contract, and a
single event may result in payments under a number of contracts. Berkshire's
present underwriting standards (which are subject to change) seek to limit
Berkshire's exposure to a loss from a single event to $1 billion in excess of
the premium earned. This business can produce extreme volatility in reported
periodic results. Accounting consequences,
    
 
                                        3
<PAGE>   35
 
however, do not influence decisions of Berkshire's management with respect to
this or any other business, and this fact plus the Group's extraordinary
financial strength are believed to be the primary reasons why the Group has
become a major provider of these coverages.
 
     Since 1992, there has been a substantial increase in catastrophe
reinsurance capacity for the industry. Most of the additional capacity has
arisen from equity capital raised by newly-formed entities. Berkshire management
has observed that, in some instances, catastrophe reinsurance prices have fallen
below the amounts that it considered adequate. The result was a decrease in the
level of business accepted in 1995. Management anticipates that the level of
business accepted in 1996, and possibly in subsequent years as well, may also be
reduced.
 
     In recent years, the Group has entered into several non-traditional
reinsurance arrangements known as finite risk contracts. These contracts have
become increasingly significant in the Group's business and the
property/casualty insurance marketplace. These reinsurance agreements provide
essentially traditional coverages but also contractually establish minimum and
maximum payouts by the reinsurer. Minimum payout requirements may call for
repayments to the reinsured, on specified dates, of sums not otherwise paid out
by the reinsurer as losses. The amount of risk transferred, while significant,
is limited. Because the period over which claims are expected to be paid can be
lengthy, the time value of money is an important element in pricing and setting
terms for these contracts. Transaction amounts and limits of indemnification are
likely to be large. In addition, a single contract may relate to loss
occurrences in a number of lines of business that span a number of years.
 
     Providers of such non-traditional products need significant financial
strength. Increased competition for such business and new accounting standards
for ceding companies have limited the number of opportunities to write such
business, particularly with respect to retroactive reinsurance coverages of past
loss events. However, the occasional acceptance of such business continues to
produce considerable premium volume.
 
     Primary or Direct Basis Insurance. The Group also writes insurance on a
primary or direct basis (policies issued in the name of and to the insured
party). The Group's primary or direct business was significantly expanded when
GEICO became a wholly owned subsidiary of Berkshire on January 2, 1996.
 
     GEICO, through its own subsidiaries, is a multiple line property casualty
insurer, the principal business of which is writing private passenger automobile
insurance. GEICO markets its policies to individuals in 48 states and the
District of Columbia by direct response methods, which is a major aspect of
GEICO's strategy to be a low-cost provider of such coverages.
 
     Other Group members engaged in primary or direct basis insurance underwrite
multiple lines of principally casualty coverages nationwide for primarily
commercial accounts. These members write business through insurance agents and
brokers. The traditional business of National Indemnity has been largely in
providing liability coverages for commercial truck and bus operators and related
commercial transportation activities that require specialized underwriting
knowledge and techniques. The Commercial Casualty Division and Professional
Liability and Special Risk Division of National Indemnity solicit and underwrite
especially large or unusual risks. Other member companies, referred to as
"homestate operations," market various commercial coverages for standard risks
to insured in an increasing number of selected states. The Group also insures
the credit card debt of policyholders through Berkshire's 82%-owned Central
States Indemnity Co. of Omaha, which markets to individuals through credit card
issuers nationwide, and provides workers' compensation insurance primarily to
employers in California through Cypress Insurance Company.
 
     Underwriting Results and "Float." The increases in reinsurance business in
recent years have produced an exceptional increase in the amount of "float"
generated by the Group. Float is an estimate of the net investable funds
provided by policyholders to the Group and held by it prior to payment of claims
and claims adjustment expenses. Float arises because of the time lapse between
the dates premiums are paid by policyholders and the dates policy costs,
primarily losses and loss adjustment expenses, are paid. Float equals the sum of
unpaid losses, unpaid loss adjustment expenses, unearned
 
                                        4
<PAGE>   36
 
premiums, and other liabilities to policyholders, less the aggregate of premium
balances receivable, amounts recoverable as reinsurance on paid and unpaid
losses, deferred policy acquisition costs, deferred charges applicable to
assumed reinsurance and prepaid income taxes. The Group generates float in
exceptional amounts relative to premium volume. Since 1967, when Berkshire
entered the insurance business, its float has grown at an annual compounded rate
of 20.7%.
 
     The "cost" of float in any year is the underwriting loss that occurs when
premiums earned by an insurer are less than losses and expenses incurred by the
insurer for the year. In years when an underwriting profit is achieved, as the
Group has in each of the past three years, the "cost" of float is negative; that
is, the Group has had access to money at no cost. The following table shows the
Group's pre-tax underwriting profit or loss (stated on the basis of generally
accepted accounting principles and not including GEICO), average float, and
approximate cost of float (compared to the year-end yield on long-term U.S.
Treasury bonds) for the past five years:

Underwriting results from the last three years have benefitted from the
profitability of the super-cat business. This business has produced underwriting
gains of approximately $152 million, $240 million, and $110 million in 1995,
1994 and 1993, respectively, but is virtually certain to produce huge losses in
some years in the future.

                                USE OF PROCEEDS
 
     Except as otherwise set forth in the Prospectus Supplement, the proceeds to
be received by Berkshire from the sale of the Debt Securities will be used for
general corporate purposes.
 
                         DESCRIPTION OF DEBT SECURITIES
 
     The following description of the terms of the Debt Securities sets forth
certain general terms and provisions of the Debt Securities to which any
Prospectus Supplement may relate. The particular terms of the Debt Securities
offered by any Prospectus Supplement and the extent, if any, to which such
general provisions may apply to the Debt Securities so offered will be described
in the Prospectus Supplement relating to such Debt Securities.
 
     The Debt Securities are to be issued under an indenture, dated as of
December 1, 1987 (the "Indenture"), between Berkshire and State Street Bank and
Trust Company (as successor trustee to The First National Bank of Boston), as
trustee (the "Trustee"). The Indenture is an exhibit to the Registration
Statement. The following summaries of certain provisions of the Indenture do not
purport to be complete and are qualified in their entirety by reference to the
provisions of the Indenture. Numerical references in parentheses below are to
sections in the Indenture. Wherever particular sections or defined terms of the
Indenture are referred to, it is intended that such sections or defined terms
shall be incorporated herein by reference.
 
GENERAL
 
     The Debt Securities offered by this Prospectus will be limited to an
aggregate initial public offering price of up to $400,000,000 or the equivalent
thereof in one or more foreign currencies or composite currencies, including the
European Currency Unit. The Indenture provides that Debt Securities in an
unlimited amount may be issued thereunder from time to time in one or more
series. (Section 301) The Debt Securities will be unsecured obligations of
Berkshire and will rank pari passu with all other unsecured and unsubordinated
obligations of Berkshire.
 
     Reference is hereby made to the Prospectus Supplement relating to the
particular series of Debt Securities offered thereby for the terms of such Debt
Securities, including, where applicable: (1) the designation, aggregate
principal amount, currency or currencies and denominations of such Debt
Securities; (2) the price (expressed as a percentage of the aggregate principal
amount thereof) at which such Debt Securities will be issued; (3) the date or
dates on which such Debt Securities will mature; (4) the currency or currencies
in which such Debt Securities are being sold and in which the principal of and
any premium and interest on such Debt Securities will be payable and, if the
holders of any such Debt Securities may elect the currency in which payments
thereon are to be made, the manner of such election; (5) the rate or rates
(which may be fixed or variable) per annum at which such Debt Securities will
bear interest; (6) the date from which such interest on such Debt Securities
will accrue, the dates on which such interest will be payable and the date on
which payment of such interest will commence; (7) the dates on which and the
price or prices at which such Debt Securities will, pursuant to any mandatory
sinking fund provision, or may, pursuant to any optional redemption or required
repayment provisions, be redeemed or repaid and the other terms and provisions
of any such optional redemption or required repayment; (8) whether such Debt
Securities are to be issued in the form of one or more Global Securities and, if
so, the identity of the Depositary for such Global Security or Securities; (9)
any additional restrictive covenants included for the benefit of holders of such
Debt Securities; (10) additional Events of Default provided with respect to such
Debt Securities; (11) whether such Debt Securities will be convertible or
exchangeable for securities of Berkshire or another issuer; and (12) any other
specific terms of or matters relating to such Debt Securities.
 
     Principal, premium, if any, and interest will be payable at the Place of
Payment designated for such Debt Securities, provided that payment of interest
may, at the option of Berkshire, be made by check mailed to the address of the
person entitled thereto as it appears in the Security Register. (Section 307)
 
                                        6
<PAGE>   38
 
     The Debt Securities will be issued only in fully registered form, without
coupons. Debt Securities of a series may be issued in the form of one or more
Global Securities, as described below under "Global Securities." Unless the
Prospectus Supplement specifies otherwise, the Debt Securities will be issued
only in denominations of $1,000 or any integral multiple thereof. The Prospectus
Supplement relating to a series of Debt Securities denominated in a foreign or
composite currency will specify the denomination thereof. (Section 302 and 305)
 
     Debt Securities of any series (other than a Global Security) will be
exchangeable into an equal aggregate principal amount of Debt Securities of the
same series (with the same interest rate and maturity date) of different
authorized denominations. (Section 305)
 
     Debt Securities (other than Global Securities) may be presented for
exchange or for registration of transfer (with the form of transfer endorsed
thereon duly executed), at the office of any transfer agent or at the office of
the Security Registrar, without service charge and upon payment of any taxes and
other governmental charges as described in the Indenture. Such transfer or
exchange will be effected upon the transfer agent or the Security Registrar, as
the case may be, being satisfied with the documents of title and identity of the
person making the request. No service charge will be made for any transfer or
exchange of the Debt Securities, but Berkshire may require payment of a sum
sufficient to cover any tax or other governmental charge payable in connection
therewith. (Section 305)
 
     Debt Securities may be issued under the Indenture as Original Issue
Discount Securities to be offered and sold at a substantial discount below their
stated principal amount which may bear no interest or interest at a rate which
is below the market rate. Federal income tax consequences and other special
considerations applicable to any such Original Issue Discount Securities will be
described in the Prospectus Supplement relating thereto. "Original Issue
Discount Securities" means any Debt Securities that provide for an amount less
than the principal amount thereof to be due and payable upon a declaration of
acceleration of the maturity thereof upon the occurrence of an Event of Default
and the continuation thereof. (Section 101)
 
GLOBAL SECURITIES
 
     The Debt Securities of a series may be issued in the form of one or more
fully registered Global Securities that will be deposited with, or on behalf of,
a depositary (the "Depositary") identified in the Prospectus Supplement relating
to such series. Unless and until it is exchanged in whole or in part for Debt
Securities in definitive registered form, a Global Security may not be
transferred except as a whole by the Depositary or any other nominee of such
Depositary or by such Depositary or any such nominee to a successor of such
Depositary or a nominee of such successor. (Section 305)
 
     The specific terms of the depositary arrangement with respect to a series
of Debt Securities will be described in the Prospectus Supplement relating to
such series. Berkshire anticipates that the following provisions will apply to
all depositary arrangements.
 
     Upon the issuance of a Global Security, the Depositary for such Global
Security will credit, on its book-entry registration and transfer system, the
respective principal amounts of the Debt Securities represented by such Global
Security to accounts of institutions that have accounts with such Depositary
("participants"). The accounts to be credited shall be designated by the
underwriters or agents of such Debt Securities or by Berkshire if such Debt
Securities are offered and sold directly by Berkshire. Ownership of beneficial
interests in such Global Security will be shown on, and the transfer of that
ownership will be effected only through, records maintained by the Depositary
for such Global Security or by participants or persons that hold through
participants. The laws of some states require that certain purchasers of
securities take physical delivery of such securities in definitive form. Such
limits and such laws may impair the ability to transfer beneficial interests in
a Global Security.
 
     So long as the Depositary for a Global Security, or its nominee, is the
registered owner of such Global Security, such Depositary or such nominee, as
the case may be, will be considered the sole owner or holder of the Debt
Securities represented by such Global Security for all purposes under the
Indenture.
 
                                        7
<PAGE>   39
 
Except as set forth below or in the Prospectus Supplement, owners of beneficial
interests in a Global Security will not be entitled to have Debt Securities of
the series represented by such Global Security registered in their names, will
not receive or be entitled to receive physical delivery of Debt Securities of
such series in definitive form and will not be considered the owners or holders
thereof under the Indenture.
 
     Principal, premium, if any, and interest payments on Debt Securities
registered in the name of a Depositary or its nominee will be made to the
Depositary or its nominee, as the case may be, as the registered owner of the
Global Security or securities representing such Debt Securities. None of
Berkshire, the Trustee, and Paying Agent or the Security Registrar will have a
responsibility or liability for any aspect of the records relating to or
payments made on account of beneficial ownership interests in a Global Security
or for maintaining, supervising or reviewing any records relating to such
beneficial ownership interests.
 
     Berkshire expects that the Depositary for a series of Debt Securities, upon
receipt of any payment of principal, premium or interest, will credit
immediately participants' accounts with payments in amounts proportionate to
their respective beneficial interests in the principal amount of the Global
Security or Securities for such Debt Securities as shown on the records of such
Depositary. Berkshire also expects that payments by participants to owners of
beneficial interests in such Global Security or Securities held through such
participants will be governed by standing instructions and customary practices,
as is now the case with securities held for the accounts of customers in bearer
form or registered in "street name," and will be the responsibility of such
participants.
 
     If a Depositary for a series of Debt Securities is at any time unwilling or
unable to continue as depositary and a successor depositary is not appointed by
Berkshire within ninety days, Berkshire will issue Debt Securities for such
series in definitive form in exchange for the Global Security or Securities
representing such Series of Debt Securities. In addition, Berkshire may at any
time and in its sole discretion determine not to have the Debt Securities of a
series represented by a Global Security or Securities and, in such event, will
issue Debt Securities of such series in definitive form in exchange for the
Global Security or Securities representing such series of Debt Securities. In
either instance, an owner of a beneficial interest in a Global Security will be
entitled to have Debt Securities of the series represented by such Global
Security equal in principal amount to such beneficial interest registered in its
name and will be entitled to physical delivery of such Debt Securities in
definitive form. Debt Securities of such series so issued in definitive form
will be issued in denominations of $1,000 and integral multiples thereof and
will be issued in registered form only, without coupons.
 
DEFEASANCE
 
     At Berkshire's option, either (1) Berkshire will be Discharged (as
hereinafter defined) from any and all obligations in respect of any series of
Debt Securities or (2) Berkshire shall cease to be under any obligations to
comply with the restriction on its ability to merge, consolidate or sell assets
as set forth in the Indenture, in either case if it deposits irrevocably with
the Trustee, in trust, specifically for the benefit of the holders of such
series, money or Government Obligations (as hereinafter defined) which through
the payment of interest thereon and principal thereof in accordance with their
terms will provide money in an amount sufficient (in the written opinion of a
nationally recognized firm of independent accountants in the case of Government
Obligations or a combination of money and Government Obligations) to pay all the
principal of, and interest on, the Debt Securities of such series on the dates
such payments are due in accordance with the terms of such Debt Securities. To
exercise such option, Berkshire is required to deliver to the Trustee an opinion
of a nationally recognized tax counsel to the effect that Holders of the Debt
Securities of such series will not recognize income, gain or loss for Federal
income tax purposes as a result of such deposit and discharge and will be
subject to Federal income tax on the same amounts and in the same manner and at
the same times as would have been the case if such deposit and discharge had not
occurred.
 
                                        8
<PAGE>   40
 
     The term "Discharged" is defined to mean that Berkshire is deemed to have
paid and discharged the entire indebtedness represented by, and obligations
under, the Debt Securities of such series, except (1) the rights of holders of
the Debt Securities of such series to receive, from the trust fund described
above, payment of the principal of and the interest on the Debt Securities of
such series when such payments are due, (2) Berkshire's obligations with respect
to the Debt Securities of such series with respect to registration, transfer,
exchange maintenance of a paying office and holding money in trust and (3) the
rights, powers, trusts, duties and immunities of the Trustee under the
Indenture.
 
     The term "Government Obligations" is defined to mean securities that are
(1) direct obligations of the United States of America for the payment of which
its full faith and credit is pledged or (2) obligations of a Person controlled
or supervised by and acting as an agency or instrumentality or the United States
of America the timely payment of which is unconditionally guaranteed as a full
faith and credit obligation by the United States of America, which, in either
case under either clause are not callable or redeemable at the option of the
issuer thereof, and also includes a depository receipt issued by a bank or trust
company as custodian with respect to any such Government Obligations or a
specific payment of interest on or principal of any such Government Obligations
held by such custodian for the account of the holder of a depository receipt,
provided that (except as required by law) such custodian is not authorized to
make any deduction from the amount payable to the holder of such depository
receipt from any amount received by the custodian in respect of the Government
Obligation or the specific payment of interest on or principal of the Government
Obligations evidenced by such depository receipt. (Article Thirteen)
 
EVENTS OF DEFAULT, WAIVER AND NOTICE
 
     Events of default with respect to any series of Debt Securities are defined
in the Indenture as being: (1) default for thirty days in payment of any
interest on any Debt Security of such series; (2) default in payment of
principal of or premium, if any, on any Debt Security of such series when due;
(3) default in the deposit of any sinking fund payment on any Debt Security of
such series when due: (4) default for ninety days after notice to Berkshire by
the Trustee or by the holders of 25% in principal amount of Debt Securities of
such series then outstanding in performance of any other covenant in the
Indenture; (5) acceleration of the maturity of any indebtedness for money
borrowed by Berkshire or any Consolidated Subsidiary (as defined) of $5,000,000
or more at the time outstanding, if such acceleration is by reason of default by
Berkshire or such Consolidated Subsidiary and is not rescinded or annulled
within ten days after notice by the Trustee or the holders of 25% in principal
amount of Debt Securities of such series then outstanding; and (6) certain
events of bankruptcy, insolvency and reorganization. (Section 501) The Indenture
provides that if an event of default specified therein with respect to any
series of Debt Securities shall occur and be continuing, either the Trustee or
the holders of 25% in principal amount of Debt Securities of such series then
outstanding may declare the principal of and accrued but unpaid interest on all
Debt Securities of such series to be due and payable. (Section 502) In certain
cases, the holders of a majority in principal amount of any series of Debt
Securities then outstanding may on behalf of the holders of all Debt Securities
of such series waive any past default or event of default with respect to Debt
Securities of such series except a default not theretofore cured in payment of
the principal of or premium, if any, or interest on any Debt Securities of such
series. (Sections 502 and 513)
 
     The Indenture contains a provision entitling the Trustee, subject to the
duty of the Trustee during default with respect to any series of Debt Securities
to act with the required standard of care, to be indemnified by the holders of
Debt Securities of such series before proceeding to exercise any right or power
under the Indenture at the request of the holders. (Section 603) The Indenture
provides that no holder of Debt Securities may institute any proceeding,
judicial or otherwise, to enforce the Indenture except in the case of failure of
the Trustee, for sixty days, to act after the Trustee has been given (1) notice
of default with respect to Debt Securities of such series, (2) a request to
enforce the Indenture by the holders of not less than 25% in aggregate principal
amount of Debt Securities of such series then outstanding and (3) an offer of
reasonable indemnity. (Section 507) This provision will not
 
                                        9
<PAGE>   41
 
prevent any holder of Debt Securities from enforcing payment of the principal
thereof and premium, if any, and interest thereon at the respective due dates
thereof. (Section 508) The holders of a majority in aggregate principal amount
of any series of Debt Securities then outstanding may direct the time, method
and place of conducting any proceedings for any remedy available to the Trustee
or exercising any trust or power conferred on it with resect to Debt Securities
of such series. However, the Trustee may refuse to follow any direction that
conflicts with law or the Indenture or that would be unjustly prejudicial to
holders of Debt Securities of such series not joining therein. (Section 512)
 
     The Indenture provides that the Trustee will, within ninety days after the
occurrence of a default with respect to any series of Debt Securities known to
it, give to the holders of Debt Securities of such series notice of such default
known to it not cured or waived, but, except in the case of a default in the
payment of principal of or premium, if any, or interest on Debt Securities of
such series, the Trustee shall be protected in withholding of such notice if it
determines in good faith that the withholding of such notice is in the interest
of the holders of Debt Securities of such series. (Section 602)
 
CONSOLIDATION, MERGER OR SALE OF ASSETS OF BERKSHIRE
 
     Berkshire shall not consolidate with or merge into any other corporation or
sell all or substantially all of its assets, unless (1) the corporation formed
by such consolidation or into which Berkshire is merged or the corporation which
acquires its assets is organized in the United States and expressly assumes all
of the obligations of Berkshire under the Indenture and (2) immediately after
giving effect to such transaction, no Event of Default, and no event which after
notice or lapse of time or both would become an Event of Default, and no event
which after notice or lapse of time or both would become an Event of Default,
shall have happened and be continuing. Upon any such consolidation, merger or
sale, the successor corporation formed by such consolidation, or into which
Berkshire is merged or to which such sale is made, shall succeed to, and be
substituted for, Berkshire under the Indenture. (Sections 801 and 802)
 
MODIFICATION AND WAIVER
 
     The Indenture permits Berkshire and the Trustee, with the consent of the
holders of 66 2/3% in principal amount of the Debt Securities at the time
outstanding thereunder and affected thereby to execute supplemental indentures
adding any provisions to or changing or eliminating any of the provisions of the
Indenture or modifying the rights of the holders of Debt Securities of such
series, except that no supplemental indenture may, without the consent of all
holders of such affected series of Debt Securities, (1) change the maturity of
Debt Securities or any installment of interest thereon or reduce the principal
amount thereof or the interest thereon, or change any place of payment or the
coin or currency in which a Debt Security is payable or affect the right of any
holder to institute suit for the enforcement of payment in accordance with the
foregoing, or (2) reduce the aforesaid percentage of Debt Securities of such
series, the consent of the holders of which is required for any such
supplemental indenture. Compliance by Berkshire with certain restrictive
covenants may be waived in particular cases with the consent of the holders of
66 2/3% in principal amount of the outstanding Debt Securities of each series
affected thereby. (Section 902)
 
                              PLAN OF DISTRIBUTION
 
     Berkshire may sell the Debt Securities in any of three ways: (1) through
underwriters or dealers; (2) through agents; or (3) directly to a limited number
of institutional purchasers or to a single purchaser. The Prospectus Supplement
with respect to the Debt Securities being offered thereby will set forth the
terms of the offering of such Debt Securities, including the name or names of
any underwriters, the purchase price of such Debt Securities and the proceeds to
Berkshire from such sale, any underwriting discounts and other items
constituting underwriters' compensation, any initial public offering price and
any discounts or concessions allowed or reallowed or paid to dealers, and any
securities exchanges on which such Debt Securities may be listed.
 
                                       10
<PAGE>   42
 
     If underwriters are used in the sale, the Debt Securities will be acquired
by the underwriters for their own account and may be resold from time to time in
one or more transactions, including negotiated transactions, at a fixed public
offering price or at varying prices determined at the time of sale. The Debt
Securities may be offered to the public through underwriting syndicates
represented by one or more managing underwriters. Any managing underwriters or
underwriters will include Salomon Brothers Inc. Unless otherwise set forth in
the Prospectus Supplement, the obligations of the underwriters to purchase Debt
Securities will be subject to certain conditions precedent and the underwriters
will be obligated to purchase all the Debt Securities offered by the Prospectus
Supplement if any of such Debt Securities are purchased. Any initial public
offering price and any discounts or concessions allowed or reallowed or paid to
dealers may be changed from time to time.
 
     Debt Securities may be sold directly by Berkshire or through agents
designated by Berkshire from time to time. Any agent involved in the offer or
sale of the Debt Securities in respect of which this Prospectus is delivered
will be named, and any commissions payable by Berkshire to such agent will be
set forth, in the Prospectus Supplement. Unless otherwise indicated in the
Prospectus Supplement, any such agent will be acting on a best efforts basis for
the period of its appointment.
 
     If so indicated in the Prospectus Supplement, Berkshire will authorize
agents, underwriters or dealers to solicit offers by certain specified
institutions to purchase Debt Securities from Berkshire at the public offering
price set forth in the Prospectus Supplement pursuant to delayed delivery
contracts providing for payment and delivery on a specified date in the future.
Such contracts will be subject only to those conditions set forth in the
Prospectus Supplement and the Prospectus Supplement will set forth the
commissions payable for solicitation of such contracts.
 
     Agents and underwriters may be entitled under agreements entered into with
Berkshire to indemnification by Berkshire against certain civil liabilities,
including liabilities under the Securities Act of 1933, or to contribution with
respect to payments which the agents or underwriters may be required to make in
respect thereof. Agents and underwriters may be customers of, engage in
transactions with, or perform services for, the company or its affiliates in the
ordinary course of business.
 
                                 ERISA MATTERS
 
     Berkshire and Salomon Brothers Inc may each be considered a "party in
interest" within the meaning of the Employee Retirement Income Security Act of
1974, as amended ("ERISA"), with respect to many employee benefit plans.
Prohibited transactions within the meaning of ERISA may arise if the Debt
Securities are acquired by a pension or other employee benefit plan with respect
to which Salomon Brothers Inc is a service provider, unless such Debt Securities
are acquired pursuant to an exemption for transactions effected on behalf of
such plan by a "qualified professional asset manager" or pursuant to any other
available exemption. Any such pension or employee benefit plan proposing to
invest in the Debt Securities should consult with its legal counsel.

</TABLE>
    
 
     In the Underwriting Agreement, the several Underwriters have agreed,
subject to the terms and conditions set forth therein, to purchase all the Notes
if any are purchased.
 
     Berkshire has been advised that the Underwriters propose to offer the Notes
to the public initially at the offering price set forth on the cover of the
Berkshire Prospectus and to certain dealers at such price less a selling
concession of not more than   % of such principal amount of the Notes; that the
Underwriters may allow, and each such dealer may reallow, to other dealers a
concession not exceeding   % of such principal amount of the Notes; and that
such public offering price and concession and reallowance may be changed by the
Underwriters after completion of the offering of the Notes.
 
     Berkshire has granted to the Underwriters an option, exercisable for 30
days from the date of the Berkshire Prospectus (or, if such 30th day shall not
be a business day, on the next business day thereafter), to purchase up to an
additional $50,000,000 aggregate principal amount of the Notes at the public
offering price set forth on the cover page of the Berkshire Prospectus, less the
underwriting discount. The Underwriters may exercise such option solely for the
purpose of covering over-allotments, if any, incurred in connection with the
sale of the Notes.
 
   
     Each of Berkshire and the Company has agreed that it will not, for a period
of 90 days after the date of the Berkshire Prospectus, without the written
consent of Salomon Brothers Inc, offer, sell or contract to sell, or otherwise
dispose of, directly or indirectly, or announce the offering of, any shares of
Common Stock, or any securities convertible into or exchangeable for, shares of
Common Stock; provided, however, that such restriction shall not affect the
ability of Berkshire, the Company or their subsidiaries to take any such actions
in connection with the offer and sale of the Notes or any exchange at or prior
to maturity pursuant to the terms of Notes; and provided, further, that the
Company may sell or register shares of Common Stock or grant options to purchase
the same, in either case, pursuant to any employee or director stock option
plan, stock ownership plan or dividend reinvestment plan of the Company in
effect as of the date of the Berkshire Prospectus.
    
 
     Berkshire and the Company have agreed in the Underwriting Agreement to
indemnify the Underwriters and their controlling persons against certain
liabilities under the Securities Act of 1933, as amended (the "Securities Act"),
or contribute to payments the Underwriters or their controlling persons may be
required to make in respect thereof. The Company and Berkshire have also agreed
to indemnify each other and their controlling persons with respect to certain
liabilities, including liabilities under the Securities Act, or contribute to
payments in respect thereof.

     Berkshire has been advised by the Underwriters (other than Salomon Brothers
Inc) that they may make a market in the Notes but they are not obligated to do
so and may discontinue such market making at any time without notice. No
assurance can be given that an active public market for the Notes will develop.
 
     In the ordinary course of their respective businesses, certain of the
Underwriters and their respective affiliates have engaged in and may in the
future engage in commercial and investment banking transactions with Berkshire,
the Company and their affiliates.

                  OWNERSHIP OF COMPANY SECURITIES BY BERKSHIRE
 
     As of the date of this Prospectus, Berkshire beneficially owns 21,370,437
shares of Common Stock, representing approximately 18% of the outstanding voting
power of the Company. Such beneficial ownership consists of (i) 10,317,806
shares of Common Stock held by subsidiaries of Berkshire and (ii) 420,000 shares
of Convertible Preferred Stock held by subsidiaries of Berkshire, which shares
are convertible, at the option of the holder, into 11,052,631 shares of Common
Stock at the current conversion rate.
 
     In October 1987, pursuant to a Purchase Agreement dated September 27, 1987,
between the Company and Berkshire (the "Purchase Agreement"), the Company issued
to certain affiliates of Berkshire an aggregate of 700,000 shares of Convertible
Preferred Stock. In the Purchase Agreement, Berkshire (which for purposes of the
Purchase Agreement includes the affiliates of Berkshire) agreed that (i)
Berkshire will not sell any Company securities owned by it to a third party
without first giving the Company or its designee a reasonable opportunity to
purchase such securities at the same price and on the same terms and conditions
proposed with respect to an anticipated sale by Berkshire to a third party, and
(ii) if the Company does not exercise its right of first refusal and buy Company
securities which Berkshire proposes to sell, Berkshire will not knowingly sell
to any one entity or group acting in concert Company securities giving such
entity or group securities which amount in the aggregate to over 5% of the
Company voting stock outstanding at the time of the sale. In the Purchase
Agreement, the Company agreed to use its best efforts to nominate and elect
Warren E. Buffett and Charles T. Munger, or two other Berkshire representatives
reasonably acceptable to the Company, to the Company's Board of Directors, so
long as Berkshire owns at least 5% of the Company's outstanding voting
securities.
 
   
     On October 31, 1995, pursuant to the terms of the Certificate of
Designation of the Convertible Preferred Stock, the Company redeemed 140,000
shares of Convertible Preferred Stock for a redemption price of $140,000,000. On
October 29, 1996, Berkshire converted the 140,000 shares of Convertible
Preferred Stock that would otherwise have been redeemed by the Company on
October 31, 1996, into 3,684,206 shares of Common Stock. If the shares called
for redemption are
    
 
                                        3
<PAGE>   51
 
not previously converted, one-third of the remaining 420,000 shares of
Convertible Preferred Stock are to be redeemed annually on each October 31 of
1997 through 1999 at $1,000 per share plus any accrued but unpaid dividends. No
cash dividends may be paid on the Common Stock, nor may the Company repurchase
any of its Common Stock, if dividends or required redemptions of the Convertible
Preferred Stock are in arrears.
 
     Berkshire has advised the Company that it is considering engaging in a
transaction at some future date that may over time result in a reduction in
Berkshire's shareholding in the Company. In this connection, Berkshire has
advised the Company that it is considering whether to sell Berkshire
Exchangeable Debt Securities, and has asked the Company, pursuant to the
Company's obligations under the Purchase Agreement, to file the Company
Registration Statement registering the Shares covered hereby. Pursuant to the
Purchase Agreement, the Company will pay certain expenses arising in connection
with such registration. In addition, the Company will waive its right of first
refusal under the Purchase Agreement with respect to the delivery of Shares in
exchange for any Berkshire Exchangeable Debt Securities.
 
     Berkshire has also advised the Company that, depending upon its evaluation
of market conditions and investment alternatives, Berkshire may effect other
types of transactions that could result in a disposition of a portion of its
shares of Common Stock, or may determine not to effect any such transaction.
Berkshire expects to remain a large shareholder of the Company even if, over
time, it disposes of a portion of its shares of Common Stock. In that
connection, Berkshire has advised the Company that Mr. Buffett, Berkshire's
Chairman and Chief Executive Officer, and Mr. Munger, its Vice Chairman, expect
to remain on the Company's Board of Directors, with Mr. Buffett continuing to
serve as Chairman of the Executive Committee. In addition, Louis A. Simpson,
President and Chief Executive Officer--Capital Operations of GEICO Corporation,
a wholly owned subsidiary of Berkshire, would expect to remain a director of the
Company and to continue serving as Chairman of the Audit Committee.
 
     Each Prospectus Supplement will set forth the number of shares of Common
Stock that would be beneficially owned by Berkshire assuming that Berkshire were
to deliver the maximum number of Shares deliverable upon exchange of the
Berkshire Exchangeable Debt Securities offered thereby at the exchange rate
applicable thereto, as well as any change in the ownership of Company securities
by Berkshire since the date of this Prospectus.
 
                          DESCRIPTION OF CAPITAL STOCK
 
     The following description of the capital stock of the Company is subject to
the detailed provisions of the Company's Certificate of Incorporation and bylaws
as currently in effect (the "Bylaws"). This description does not purport to be
complete or to give full effect to the terms of the provisions of statutory or
common law and is subject to, and qualified in its entirety by reference to, the
Certificate of Incorporation and the Bylaws, each of which has been incorporated
by reference as an exhibit to the Company Registration Statement of which this
Prospectus is a part.
 
COMMON STOCK
 
   
     As of the date of this Prospectus, the Company's Certificate of
Incorporation authorizes the issuance of 250,000,000 shares of Common Stock. As
of November 20, 1996, 109,039,278 shares of Common Stock were outstanding.
    
 
     Subject to the rights of the holders of any outstanding shares of preferred
stock, holders of Common Stock are entitled to receive such dividends, in cash,
securities, or property, as may from time to time be declared by the Board of
Directors. Subject to the provisions of the Bylaws with respect to the closing
of the transfer books and the fixing of a record date, holders of shares of
Common Stock are entitled to one vote per share of Common Stock held on all
matters requiring a vote of the holders of Common Stock. In the event of any
liquidation, dissolution or winding up of the Company, either voluntary or
involuntary, after payment shall have been made to the holders of preferred
stock of the full amount to which they shall be entitled, the holders of Common
Stock shall
 
                                        4
<PAGE>   52
 
be entitled to share ratably, according to the number of shares held by them, in
all remaining assets of the Company available for distribution. Shares of Common
Stock are not redeemable and have no subscription, conversion or preemptive
rights.
 
     The outstanding shares of Common Stock are listed on the New York Stock
Exchange and trade under the symbol "SB." The transfer agent and registrar for
the Common Stock is First Chicago Trust Company of New York.
 
PREFERRED STOCK
 
     The Company is authorized by its Certificate of Incorporation to issue
5,000,000 shares of preferred stock, without par value, which may be issued from
time to time in one or more series and, subject to the provisions of the
Certificate of Incorporation applicable to all series of preferred stock, shall
have such designations, voting powers, preferences and relative, participating,
optional or other special rights, and qualifications, limitations or
restrictions thereof, as shall be stated in the resolution or resolutions
providing for the issue thereof adopted by the Company's Board of Directors or a
duly authorized committee thereof.
 
     As of the date of this Prospectus, the Company has outstanding (i) 400,000
shares of 8.08% Cumulative Preferred Stock, Series D, (ii) 500,000 shares of
8.40% Cumulative Preferred Stock, Series E, and (iii) 420,000 shares of
Convertible Preferred Stock. See "Ownership of Company Securities by Berkshire."
Each outstanding series of preferred stock ranks on parity as to the payment of
dividends and the distribution of assets upon liquidation, dissolution or
winding up. There are also currently authorized and reserved for issuance
690,000 shares of 9.50% Cumulative Preferred Stock, Series F (the "Series F
Preferred Stock"), which shares are issuable pursuant to purchase contracts of
the Company, each of which requires the purchase on June 30, 2021 (or earlier if
accelerated by the Company) of a depositary share representing one-twentieth of
a share of Series F Preferred Stock. These purchase contracts were issued in
connection with the offering by SI Financing Trust I of 13,800,000 9 1/2% Trust
Preferred Stock(SM) (TRUPS(SM)) Units, each consisting of a 9 1/4% Preferred
Security fully and unconditionally guaranteed by the Company and one purchase
contract.
 
     There are currently reserved for issuance up to 2,500,000 shares of Series
B Junior Participating Preferred Stock of the Company, which shares are issuable
upon the exercise of certain preferred share purchase rights (collectively, the
"Rights"). The Rights will become exercisable only if a person or group (other
than Berkshire and its affiliates) acquires or (unless exercisability is delayed
by the Company's Board of Directors) announces an offer to acquire 20% or more
(which percentage may be reduced to not less than 10% by the Company's Board of
Directors prior to the time the Rights become exercisable) of the outstanding
shares of Common Stock. Shares of Series B Junior Participating Preferred Stock
issued upon the exercise of the Rights will rank junior to all shares of any
other class of the Company's preferred stock with respect to the payment of
dividends and the distribution of assets upon liquidation, dissolution or
winding up.
 
                              PLAN OF DISTRIBUTION
 
     The Shares covered hereby will be deliverable only upon exchange of the
Berkshire Exchangeable Debt Securities, and may include shares of Common Stock
currently owned by Berkshire or its affiliates and/or shares of Common Stock
hereafter acquired by Berkshire or its affiliates upon conversion of shares of
Convertible Preferred Stock, through open market purchases, or in privately
negotiated transactions. See "Ownership of Company Securities by Berkshire."
 
     Berkshire may sell the Berkshire Exchangeable Debt Securities in any of
three ways: (i) through underwriting syndicates represented by one or more
managing underwriters or through one or more underwriters; (ii) through agents
designated from time to time; or (iii) directly to institutional purchasers. Any

                                        5

Brothers. The Berkshire Prospectus will set forth the terms of the offering of
the Berkshire Exchangeable Debt Securities, including the name or names of any
underwriters or agents, the purchase price of such Berkshire Exchangeable Debt
Securities and the proceeds to Berkshire from such sale, any underwriting
discounts and other items constituting underwriters' compensation, any initial
public offering price and any discounts or concessions allowed or reallowed or
paid to dealers, and any securities exchanges on which such Berkshire
Exchangeable Debt Securities may be listed.

for such purpose, this Prospectus also may be used by Berkshire in connection
with any exchange of Berkshire Exchangeable Debt Securities for Common Stock at
the option of the holder.

beneficially owns Common Stock and Convertible Preferred Stock representing
approximately 18% of the outstanding voting power of the Company. Mr. Buffett,

ownership and other relationships between Salomon Brothers and Berkshire,
Berkshire may be deemed to be an affiliate of Salomon Brothers. Accordingly, any
offering of the Shares covered hereby will be made pursuant to the provisions of
Rule 2720 of the Conduct Rules of the National Association of Securities
Dealers, Inc.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
     Section 145 of the General Corporation Law of Delaware empowers Berkshire
to indemnify, subject to the standards therein prescribed, any person in
connection with any action, suit or proceeding brought or threatened by reason
of the fact that such person is or was a director, officer, employee or agent of
Berkshire or is or was serving as such with respect to another corporation or
other entity at the request of Berkshire. Section 10 of Berkshire's By-Laws
provides that Berkshire shall, to the fullest extent permitted by Section 145 of
the General Corporation Law of Delaware, indemnify directors and officers of
Berkshire from and against any and all of the expenses, liabilities or other
matters referred to in or covered by said Section. Additionally, as permitted by
said Section and Berkshire's By-Laws, Berkshire has entered into Indemnification
Agreements with each of its Directors and Officers. The description of these
Indemnification Agreements under the caption "Summary of the Indemnification
Agreements" on page 9 of Berkshire's definitive proxy statement for its May 19,
1987 Annual Meeting of Stockholders, Commission File No. 0-7413, is incorporated
herein by reference.
 
     As permitted by Section 102 of the General Corporation Law of Delaware,
Berkshire's Restated Certificate of Incorporation includes as Article Tenth
thereof a provision eliminating, to the extent permitted by Delaware law, the
personal liability of each director of Berkshire to Berkshire or any of its
shareholders for monetary damages resulting from breaches of such director's
fiduciary duty of care.

ITEM 17. UNDERTAKINGS.
 
     The undersigned Registrant hereby undertakes:
 
          (1) That, for purposes of determining any liability under the
     Securities Act of 1933, the information omitted from the form of prospectus
     filed as part of a registration statement in reliance upon Rule 430A and
     contained in the form of prospectus filed by Berkshire pursuant to Rule
     424(b)(1) or (4) under the Securities Act shall be deemed to be part of the
     registration statement as of the time it was declared effective;
 
          (2) That, for the purpose of determining any liability under the
     Securities Act of 1933, each post-effective amendment that contains a form
     of prospectus and each filing of Berkshire's annual report pursuant to
     Section 13(a) or 15(d) of the Securities Exchange Act of 1934 that is
     incorporated by reference into 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;
 
          (3) To file, during any period in which offers or sales are being
     made, a post-effective amendment to this registration statement 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; and
 
          (4) To remove from registration by means of a post-effective amendment
     any of the securities being registered which remain unsold at the
     termination of the offering.
 
     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of
Berkshire pursuant to the provisions described under Item 15 above, or
otherwise, Berkshire has been advised that in the opinion of the Commission such
indemnification is against public policy as expressed in the Securities Act and
is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by Berkshire of expenses
incurred or paid by a director, officer or controlling person of Berkshire 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, Berkshire will, unless in the opinion of its counsel the matter has
been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.

an option to purchase up to $[50,000,000] principal face amount of such
securities (the "Option Securities" and, together with the Underwritten

Final Berkshire Prospectus, cash with an equal value), at the rate specified in
the Final Berkshire Prospectus. The Securities may also, at the option of the
holders and subject to certain conditions, be exchanged into Salomon Common
Stock at such rate during certain periods.

                  In connection with the foregoing and pursuant to the Purchase
Agreement dated September 27, 1987 between Berkshire and Salomon, as amended
(the "Purchase Agreement") Salomon has filed with the Commission a registration

Salomon Common Stock, in respect of the Underwritten Securities, plus an
additional ________ shares (the "Option Shares" and, together with the
Underwritten Shares, the "Shares") of Salomon Common Stock in respect of the
Option Securities, for sale by Berkshire as a selling stockholder (to the extent
Berkshire shall so elect to deliver to holders of the Securities, or holders of
the Securities shall so elect to receive during specified periods, Salomon
Common Stock pursuant to the terms of the Securities), which registration
statement is referred to in Section 2 of this Agreement, and Salomon , by action
of its Board of Directors, has waived its right of first refusal under Section
10(b)(iii) of the Purchase Agreement with respect to such a sale of the Shares
by Berkshire.

                  Certain terms used in this Agreement are defined in paragraph

the Act during each Exchange Period (as defined in the Final Berkshire
Prospectus) in order to permit a prospectus to be usable by Berkshire in
connection with any exchange of Securities, pursuant to the terms thereof, at
the option of the holders thereof. It is understood and agreed that Salomon may
delay the effectiveness of any registration statement or the delivery of any
Salomon prospectus if Salomon determines in good faith and for valid business
reasons that delivery of a Salomon prospectus would not be in the best interest
of Salomon or is prohibited by applicable law. Salomon shall notify Berkshire of
any delay pursuant to the immediately preceding sentence and Berkshire shall not
use any Salomon prospectus previously furnished to it during the period of such
delay.

                  3. Purchase and Sale. (a) Subject to the terms and conditions
and in reliance upon the representations and warranties herein set forth,
Berkshire agrees to sell to each Underwriter, and each Underwriter agrees,
severally and not jointly, to purchase from Berkshire, at purchase price of ___%
of the principal face amount thereof, plus amortization of original issue
discount, if any, on the Securities from November __, 1996 to the Closing Date,
the principal face amount of the Securities set forth opposite such
Underwriter's name in Schedule I hereto.

                  (b) Subject to the terms and conditions and in reliance upon
the representations and warranties herein set forth, Berkshire hereby grants an
option to the several Underwriters to purchase, severally and not jointly, up to
$_______ principal face amount of the Option Securities at the same purchase
price as the Underwriters shall pay for the Underwritten Securities. Said option
may be exercised only to cover over-allotments in the sale of the Underwritten
Securities by the Underwriters. Said option may be exercised in whole or in part
at any time (but not more than once) on or before the 30th day after the date of
the Final Berkshire Prospectus upon written or telegraphic notice by the
Representatives to Berkshire setting forth the number of the Option Securities
as to which the several Underwriters are exercising the option and the
settlement date. Delivery of certificates for the Option Securities, and payment
therefor, shall be made as provided in Section 4 hereof. The principal amount of
Option Securities to be purchased by each Underwriter shall be the same
percentage of the total principal face amount of Option Securities to be
purchased by the several Underwriters as such Underwriter is purchasing of the
Underwritten Securities, subject to such adjustments as you in your absolute
discretion shall make to round the denominations of the Securities to integral
multiples of $1,000.

                  4. Delivery and Payment. Delivery of and payment for the
Underwritten Securities and the Option Securities (if the option provided for in
Section 3(b) hereof shall have been exercised on or before the first business
day prior to the Closing Date) shall be made at 

                                       7
<PAGE>   8
10:00 AM, New York City time, on November __, 1996, (or such later date not
later than five business days after such specified date as the Representatives
shall designate) which date and time may be postponed by agreement between the
Representatives and Berkshire or as provided in Section 11 hereof (such date and
time of delivery and payment for the Securities being herein called the "Closing
Date"). Delivery of the Securities shall be made to the Representatives for the
respective accounts of the several Underwriters against payment by the several
Underwriters through the Representatives of the purchase price thereof to or
upon the order of Berkshire either by certified or official bank check or checks
drawn on or by a New York Clearing House bank or by wire transfer to an account
designated in writing by Berkshire at least two business days in advance of the
Closing Date, and in either case payable in same-day funds. Delivery of the
Securities shall be made through the facilities of The Depository Trust Company.

                  Berkshire agrees to have the Securities available for
inspection and checking by the Representatives in New York, New York, not later
than 1:00 PM on the business day prior to the Closing Date.

                  If the option provided for in Section 3(b) hereof is exercised
after the first business day prior to the Closing Date, Berkshire will deliver
(at the expense of Berkshire) to the Representatives at Seven World Trade
Center, New York, New York, on the date specified by the Representatives (which
shall be within three business days after exercise of said option), certificates
for the Option Securities in such names and denominations as the Representatives
shall have requested against payment of the purchase price thereof to or upon
the order of Berkshire either by certified or official bank check or checks
drawn on or by a New York Clearing House bank or by wire transfer to an account
designated in writing by Berkshire at least two business days in advance of the
Closing Date, and in either case payable in same-day funds. If settlement for
the Option Securities occurs after the Closing Date, Berkshire and Salomon will
deliver to the Representatives on the settlement date for the Option Securities,
and the obligation of the Underwriters to purchase the Option Securities shall
be conditioned upon receipt of, supplemental opinions and certificates
confirming as of such date certain of the opinions and certificates, as
requested by the Underwriters, delivered on the Closing Date pursuant to Section
7 hereof.

                  5. Offering by Underwriters. It is understood that the several
Underwriters propose to offer the Securities for sale to the public as set forth
in the Final Berkshire Prospectus.

                  6. Agreements of Berkshire. Berkshire agrees with the several
Underwriters that:

                  (a) Berkshire will use its best efforts to cause the Berkshire
Registration Statement, if not effective at the Execution Time, and any
amendment thereto to become effective. Prior to the termination of the offering
of the Securities, Berkshire will not file any amendment of the Berkshire
Registration Statement or supplement (including the Final Berkshire Prospectus
or any Preliminary Final Berkshire Prospectus) to the Basic Berkshire Prospectus
unless Berkshire has furnished you a copy for your review prior to filing and
will not file any such proposed amendment or supplement to which you reasonably
object. Subject to the foregoing sentence, Berkshire will cause the Final
Berkshire Prospectus, properly completed, and 

                                       8
<PAGE>   9
any supplement thereto to be filed with the Commission, if required, pursuant to
the applicable paragraph of Rule 424(b) within the time period prescribed and
will provide evidence satisfactory to the Representatives of such timely filing.
Berkshire will promptly advise the Representatives (i) when the Berkshire
Registration Statement, if not effective at the Execution Time, and any
amendment thereto, shall have become effective, (ii) when the Final Berkshire
Prospectus, and any supplement thereto, shall have been filed with the
Commission pursuant to Rule 424(b), (iii) when, prior to termination of the
offering of the Securities, any amendment to the Berkshire Registration
Statement shall have been filed or become effective, (iv) of any request by the
Commission for any amendment of the Berkshire Registration Statement or
supplement to the Final Berkshire Prospectus or for any additional information,
(v) of the issuance by the Commission of any stop order suspending the
effectiveness of the Berkshire Registration Statement or the institution or
threatening of any proceeding for that purpose and (vi) of the receipt by
Berkshire of any notification with respect to the suspension of the
qualification of the Securities for sale in any jurisdiction or the initiation
or threatening of any proceeding for such purpose. Berkshire will use its best
efforts to prevent the issuance of any such stop order and, if issued, to obtain
as soon as possible the withdrawal thereof.

                  (b) If, at any time when a prospectus relating to the
Securities is required to be delivered under the Act, any event occurs as a
result of which the Final Berkshire Prospectus as then supplemented would
include any untrue statement of a material fact or omit to state any material
fact necessary to make the statements therein in the light of the circumstances
under which they were made not misleading, or if it shall be necessary to amend
the Berkshire Registration Statement or supplement the Final Berkshire
Prospectus to comply with the Act or the Exchange Act or the respective rules
thereunder, Berkshire promptly will prepare and file with the Commission,
subject to the second sentence of paragraph (a) of this Section 6, an amendment
or supplement which will correct such statement or omission or effect such
compliance.

                  (c) As soon as practicable, Berkshire will make generally
available to its security holders and to the Representatives an earnings
statement or statements of Berkshire and its subsidiaries which will satisfy the
provisions of Section 11(a) of the Act and Rule 158 under the Act.

                  (d) Berkshire will furnish to the Representatives and counsel
for the Underwriters, without charge, copies of the Berkshire Registration
Statement (including exhibits thereto), and to each other Underwriter a copy of
the Berkshire Registration Statement (without exhibits thereto) and so long as
delivery of a prospectus by an Underwriter or any dealer may be required by the
Act, as many copies of each Preliminary Final Berkshire Prospectus and the Final
Berkshire Prospectus and any supplement thereto as the Representatives may
reasonably request.

                  (e) Berkshire will arrange for the qualification of the
Securities and the Shares for sale under the laws of such jurisdictions as the
Representatives may designate and will maintain such qualifications in effect so
long as required for the distribution of the Securities and the Shares;
provided, however, that in connection therewith, Berkshire shall not be required
to qualify as a foreign corporation or to file a general consent to service of
process in any 

                                       9
<PAGE>   10
jurisdiction. Berkshire will pay the fee of the National Association of
Securities Dealers, Inc. in connection with any review of the offering by it.

                  (f) Until the 90th business day following the Execution Time,
Berkshire will not, without the prior written consent of Salomon Brothers Inc,
offer, sell or contract to sell, or otherwise dispose of, directly or
indirectly, or announce the offering of, any shares of Salomon Common Stock, or
any securities convertible into or exchangeable for, shares of Salomon Common
Stock; provided, however, that the foregoing shall not restrict the ability of
Berkshire or its subsidiaries to take any such actions in connection with the
offer and sale of shares of Salomon Common Stock in connection with the offering
of the Securities or any exchange or redemption of the Securities in accordance
with their terms.

                  7. Agreements of Salomon. Salomon agrees with the several
Underwriters that:

                  (a) Salomon will use its best efforts to cause the Salomon
Registration Statement, if not effective at the Execution Time, and any
amendment thereof, to become effective. Prior to the termination of the offering
of the Securities, Salomon will not file any amendment of the Salomon
Registration Statement or supplement to the Salomon Prospectus unless Salomon
has furnished you a copy for your review prior to filing and will not file any
such proposed amendment or supplement to which you reasonably object. Subject to
the foregoing sentence, if the Salomon Registration Statement has become or
becomes effective pursuant to Rule 430A, or filing of the Salomon Prospectus is
otherwise required under Rule 424(b), Salomon will cause the Salomon Prospectus,
properly completed, and any supplement thereto to be filed with the Commission
pursuant to the applicable paragraph of Rule 424(b) within the time period
prescribed and will provide evidence satisfactory to the Representatives of such
timely filing. Salomon will promptly advise the Representatives (i) when the
Salomon Registration Statement, if not effective at the Execution Time, and any
amendment thereto, shall have become effective, (ii) when the Salomon
Prospectus, and any supplement thereto, shall have been filed (if required) with
the Commission pursuant to Rule 424(b), (iii) when, prior to termination of the
offering of the Shares, any amendment to the Salomon Registration Statement
shall have been filed or become effective, (iv) of any request by the Commission
for any amendment of the Salomon Registration Statement or supplement to the
Salomon Prospectus or for any additional information, (v) of the issuance by the
Commission of any stop order suspending the effectiveness of the Salomon
Registration Statement or the institution or threatening of any proceeding for
that purpose and (vi) of the receipt by Salomon of any notification with respect
to the suspension of the qualification of the Shares for sale in any
jurisdiction or the initiation or threatening of any proceeding for such
purpose. Salomon will use its best efforts to prevent the issuance of any such
stop order and, if issued, to obtain as soon as possible the withdrawal thereof.

                  (b) If, at any time when a prospectus relating to the Shares
is required to be delivered under the Act in connection with the distribution of
the Securities, any event occurs as a result of which the Salomon Prospectus as
then supplemented would include any untrue statement of a material fact or omit
to state any material fact necessary to make the statements therein in the light
of the circumstances under which they were made not misleading, or if it shall

                                       10
<PAGE>   11
be necessary to amend the Salomon Registration Statement or supplement the
Salomon Prospectus to comply with the Act or the Exchange Act or the respective
rules thereunder, Salomon promptly will notify the Representatives and prepare
and file with the Commission, subject to the second sentence of paragraph (a) of
this Section 7, an amendment or supplement which will correct such statement or
omission or effect such compliance.

                  (c) As soon as practicable, Salomon will make generally
available to its security holders and to the Representatives an earnings
statement or statements of Salomon and its subsidiaries which will satisfy the
provisions of Section 11(a) of the Act and Rule 158 under the Act.

                  (d) Salomon will furnish to the Representatives and counsel
for the Underwriters, without charge, signed copies of the Salomon Registration
Statement (including exhibits thereto), and to each other Underwriter a copy of
the Salomon Registration Statement (without exhibits thereto) and so long as
delivery of a prospectus by an Underwriter or any dealer may be required by the
Act, as many copies of each Preliminary Salomon Prospectus and the Salomon
Prospectus and any supplement thereto as the Representatives may reasonably
request.

                  (e) Salomon will arrange for the qualification of the Shares
for sale under the laws of such jurisdictions as the Representatives may
designate and will maintain such qualifications in effect so long as required
for the distribution of the Securities and the Shares; provided, however, that
in connection therewith, Salomon shall not be required to qualify as a foreign
corporation or to file a general consent to service of process in any
jurisdiction.

                  (f) Until the 90th business day following the Execution Time,
Salomon will not without the prior written consent of Salomon Brothers Inc,
offer, sell or contract to sell, or otherwise dispose of, directly or
indirectly, or announce the offering of, any shares of Salomon Common Stock or
any securities convertible into, or exchangeable for, shares of Salomon Common
Stock (other than the Shares in connection with the offering by Berkshire of the
Securities); provided, however, that the foregoing shall not restrict the
ability of Salomon or its subsidiaries to take such actions in connection with
the offering by Berkshire of the Securities or any exchange or redemption of the
Securities in accordance with their terms; and provided, further, that Salomon
may sell or register shares of Salomon Common Stock or grant options to purchase
the same, in either case, pursuant to any employee or director stock option
plan, stock ownership plan or dividend reinvestment plan of Salomon in effect at
the Execution Time.

                  8. Conditions to the Obligations of the Underwriters. The
obligations of the Underwriters to purchase the Underwritten Securities and the
Option Securities, as the case may be, shall be subject to the accuracy of the
representations and warranties on the part of Berkshire and Salomon contained
herein as of the Execution Time, the Closing Date and any settlement date
pursuant to Section 4 hereof, to the accuracy of the statements of Berkshire and
Salomon made in any certificates pursuant to the provisions hereof, to the
performance by Berkshire and Salomon of their respective obligations hereunder
and to the following additional conditions:

                  (a) If the Berkshire Registration Statement or the Salomon
Registration Statement has not become effective prior to the Execution Time,
unless the Representatives agrees in 

                                       11
<PAGE>   12
writing to a later time, such Berkshire or Salomon Registration Statement will
become effective not later than (i) 6:00 PM, New York City time, on the date of
determination of the public offering price, if such determination occurred at or
prior to 3:00 PM, New York City time, on such date or (ii) 12:00 Noon, New York
City time, on the business day following the day on which the public offering
price was determined, if such determination occurred after 3:00 PM, New York
City time, on such date; if filing of the Final Berkshire Prospectus or the
Salomon Prospectus, or any supplements thereto, is required pursuant to Rule
424(b), such Final Berkshire Prospectus or Salomon Prospectus, and any such
supplements, will be filed in the manner and within the time period required by
Rule 424(b); and no stop order suspending the effectiveness of the Berkshire
Registration Statement or the Salomon Registration Statement shall have been
issued and no proceedings for that purpose shall have been instituted or
threatened.

                  (b) Berkshire shall have furnished to the Representatives the
opinion of Munger, Tolles & Olson, counsel for Berkshire, dated the Closing
Date, to the effect that:

                  (i) each of Berkshire and National Indemnity Company, Columbia
         Insurance Company and Government Employees Insurance Company
         (individually a "Subsidiary" and collectively the "Subsidiaries") has
         been duly incorporated and is validly existing as a corporation in good
         standing under the laws of the jurisdiction in which it is chartered or
         organized, with full corporate power and authority to own its
         properties and conduct its business as described in the Final Berkshire
         Prospectus, and is duly qualified to do business as a foreign
         corporation and is in good standing under the laws of each jurisdiction
         which requires such qualification where it owns or leases material
         properties or conducts material business, except for any such
         jurisdiction where the failure to be so qualified would not have a
         material adverse effect on such Subsidiary; and Berkshire is not
         required to register as an investment company under the Investment
         Company Act of 1940;

                  (ii) all the outstanding shares of capital stock of each
         Subsidiary have been duly and validly authorized and issued and are
         fully paid and nonassessable, and, except as otherwise set forth in the
         Final Berkshire Prospectus, all outstanding shares of capital stock of
         the Subsidiaries are owned by Berkshire either directly or through
         wholly owned subsidiaries free and clear of any perfected security
         interest and such counsel is not aware of any other security interests,
         claims, liens or encumbrances;

                  (iii) Berkshire's authorized equity capitalization is as set
         forth in the Final Berkshire Prospectus; the Securities conform to the
         description thereof contained in the Final Berkshire Prospectus; and
         authorization has been given to list the Securities on the NYSE,
         subject to official notice of issuance and evidence of satisfactory
         distribution, or Berkshire has filed a preliminary listing application
         and all required supporting documents with respect to the Securities
         with the NYSE and such counsel has no reason to believe that the
         Securities will not be authorized for listing, subject to official
         notice of issuance and evidence of satisfactory distribution;

                                       12
<PAGE>   13
                  (iv) the Indenture has been duly authorized, executed and
         delivered, has been duly qualified under the Trust Indenture Act and
         constitutes a legal, valid and binding obligation enforceable against
         Berkshire in accordance with its terms (subject, as to enforcement of
         remedies, to applicable bankruptcy, reorganization, insolvency,
         moratorium or other laws affecting creditors' rights generally from
         time to time in effect and equitable principles relating to the
         granting of specific performance and other equitable remedies as a
         matter of judicial discretion); and the Securities have been duly
         authorized, executed and delivered by Berkshire and, when authenticated
         by the Trustee in accordance with the provisions of the Indenture and
         delivered to and paid for by the Underwriters pursuant to this
         Agreement, will constitute legal, valid and binding obligations of
         Berkshire entitled to the benefits of the Indenture;

                  (v) to the best knowledge of such counsel, there is no pending
         or threatened action, suit or proceeding before any court or
         governmental agency, authority or body or any arbitrator involving
         Berkshire or any of its subsidiaries, of a character required to be
         disclosed in the Berkshire Registration Statement which is not
         adequately disclosed in the Final Berkshire Prospectus, and there is no
         franchise, contract or other document of a character required to be
         described in the Berkshire Registration Statement or Final Berkshire
         Prospectus, or to be filed as an exhibit, which is not described or
         filed as required;

                  (vi) the Berkshire Registration Statement has become effective
         under the Act; any required filing of the Basic Berkshire Prospectus,
         any Preliminary Final Berkshire Prospectus and the Final Berkshire
         Prospectus, and any supplements thereto, pursuant to Rule 424(b) has
         been made in the manner and within the time period required by Rule
         424(b); to the best knowledge of such counsel, no stop order suspending
         the effectiveness of the Berkshire Registration Statement has been
         issued, no proceedings for that purpose have been instituted or
         threatened, and the Berkshire Registration Statement and the Final
         Berkshire Prospectus (other than the financial statements and other
         financial and statistical information contained or incorporated therein
         and the Salomon Prospectus, as to which such counsel need express no
         opinion) comply as to form in all material respects with the applicable
         requirements of the Act, the Exchange Act and the Trust Indenture Act
         and the respective rules thereunder; and such counsel has no reason to
         believe that at the Berkshire Effective Date the Berkshire Registration
         Statement (other than the financial statements and other financial and
         statistical information contained or incorporated therein and the
         Salomon Prospectus, as to which such counsel need express no opinion)
         contained any untrue statement of a material fact or omitted to state
         any material fact required to be stated therein or necessary to make
         the statements therein not misleading or that the Final Berkshire
         Prospectus (other than the financial statements and other financial and
         statistical information contained or incorporated therein and the
         Salomon Prospectus, as to which such counsel need express no opinion)
         includes any untrue statement of a material fact or omits to state a
         material fact necessary to make the statements therein, in the light of
         the circumstances under which they were made, not misleading;

                                       13
<PAGE>   14
                  (vii) this Agreement has been duly authorized, executed and
         delivered by Berkshire;

                  (viii) no consent, approval, authorization, order,
         registration or qualification of or with any court or governmental
         agency or body is required for the consummation of the transactions
         contemplated herein, except such as have been obtained under the Act,
         the Exchange Act and the Trust Indenture Act and such as may be
         required under the state securities or blue sky laws in connection with
         the purchase and distribution of the Securities and the Shares by the
         Underwriters and such other approvals (specified in such opinion) as
         have been obtained;

                  (ix) neither the issue and sale of the Securities, nor the
         consummation of any other of the transactions herein contemplated nor
         the fulfillment of the terms hereof will conflict with, result in a
         breach of, or constitute a default under the charter or by-laws of
         Berkshire or the terms of any indenture or other agreement or
         instrument known to such counsel and to which Berkshire or any of its
         subsidiaries is a party or bound, or any order or regulation known to
         such counsel to be applicable to Berkshire or any of its subsidiaries
         of any court, regulatory body, administrative agency, governmental body
         or arbitrator having jurisdiction over Berkshire or any of its
         subsidiaries; and

                  (x) no holder of securities of Berkshire has rights to the
         registration of such securities under the Berkshire Registration
         Statement.

                  In rendering such opinion, such counsel may rely (A) as to
matters involving the application of laws of any jurisdiction other than the
States of California and Delaware (and as to Delaware, involving the application
of any law other than the Delaware General Corporation Law) or the United
States, to the extent deemed proper and specified in such opinion, upon the
opinion of other counsel of good standing believed to be reliable and who are
satisfactory to counsel for the Underwriters, (B) to the extent such opinion
relates to the law of the State of New York (which law the Indenture, this
Agreement and the Securities state to be the governing law thereof), assume that
the laws of the State of California are the same as those of the State of New
York and (C) as to matters of fact, to the extent deemed proper, on certificates
of responsible officers of Berkshire and public officials. References to the
Final Berkshire Prospectus in this paragraph (b) include any supplements thereto
at the Closing Date.

                  (c) Salomon shall have furnished to the Representatives the
opinion of Cravath, Swaine & Moore, counsel for Salomon, or Arnold S. Olshin,
Secretary for Salomon, dated the Closing Date, to the effect, in the aggregate,
that:

                  (i) each of Salomon and Salomon Brothers Inc. ("SBI") has been
         duly incorporated and is validly existing as a corporation in good
         standing under the laws of the jurisdiction in which it is chartered or
         organized, with full corporate power and authority to own its
         properties and conduct its business as described in the Salomon
         Prospectus;

                                       14
<PAGE>   15
                  (ii)  Salomon's authorized equity capitalization is as set
         forth in the Salomon Prospectus; the capital stock of Salomon conforms
         to the description thereof contained in the Salomon Prospectus; the
         outstanding shares of Salomon Common Stock have been duly and validly
         authorized and issued and are fully paid and nonassessable; the shares
         of Salomon Common Stock (the "Conversion Shares") issuable on
         conversion of Salomon's 9% Series A Cumulative Convertible Preferred
         Stock (the "Convertible Preferred Stock") shall upon conversion of the
         Convertible Preferred Stock in accordance with its terms be duly
         issued, fully paid and nonassessable; and no holders of securities of
         Salomon are entitled to preemptive or other rights to subscribe for the
         Conversion Shares;

                  (iii) to the best knowledge of such counsel, there is no
         pending or threatened action, suit or proceeding before any court or
         governmental agency, authority or body or any arbitrator involving
         Salomon or any of its subsidiaries, of a character required to be
         disclosed in the Salomon Registration Statement which is not adequately
         disclosed in the Salomon Prospectus; and the statements included or
         incorporated in the Salomon Prospectus describing any legal proceedings
         relating to Salomon fairly summarize such matters;

                  (iv)  the Salomon Registration Statement has become effective
         under the Act; any required filing of any Salomon Prospectus, and any
         supplements thereto, pursuant to Rule 424(b) has been made in the
         manner and within the time period required by Rule 424(b); to the best
         knowledge of such counsel, no stop order suspending the effectiveness
         of the Salomon Registration Statement has been issued, and no
         proceedings for that purpose have been instituted or threatened; the
         Salomon Registration Statement and the Salomon Prospectus (other than
         the financial statements and other financial and statistical
         information contained therein as to which such counsel need not express
         any opinion) appeared on their face to be appropriately responsive in
         all material respects with the requirements of the Act and the
         respective rules and regulations thereunder; and such counsel has no
         reason to believe that at the Salomon Effective Date, the Salomon
         Registration Statement contained any untrue statement of a material
         fact or omitted to state any material fact required to be stated
         therein or necessary to make the statements therein not misleading, or
         that at the Closing Date, the Salomon Prospectus (other than the
         financial statements and other financial and statistical information
         contained therein) includes any untrue statement of a material fact or
         omits to state a material fact necessary to make the statements
         therein, in the light of the circumstances under which they were made,
         not misleading;

                  (v)   this Agreement has been duly authorized, executed and
         delivered by Salomon;

                  (vi)  no consent, approval, authorization or order of any 
         court or governmental body or agency is required for the consummation
         by Salomon of the transactions contemplated herein, except such as have
         been obtained under the Act (other than in connection with any exchange
         of the Securities at the option of the holder thereof) and such as may
         be required under the blue sky laws of any jurisdiction in connection
         with 


                                       15


<PAGE>   16
         the sale of the Securities by the Underwriters and the distribution of
         the Shares pursuant to the terms of the Securities and such other
         approvals (specified in such opinion) as have been obtained;

                  (vii)  neither the issue and sale of the Securities nor the
         delivery of the Shares upon exchange of the Securities, nor the
         consummation of any other of the transactions herein contemplated nor
         the fulfillment of the terms hereof will conflict with, result in a
         breach of, or constitute a default under the charter or by-laws of
         Salomon or the terms of any indenture or other agreement or instrument
         known to such counsel and to which Salomon or any of its subsidiaries
         is a party or bound, or any order or regulation known to such counsel
         to be applicable to Salomon or any of its subsidiaries of any court,
         regulatory body, administrative agency, governmental body or arbitrator
         having jurisdiction over Salomon or any of its subsidiaries; and

                  (viii) no holder of securities of Salomon, other than
         Berkshire, has rights to the registration of such securities under the
         Salomon Registration Statement.

                  In rendering such opinion, such counsel may rely (A) as to
matters involving the application of laws of any jurisdiction other than the
States of New York and Delaware or the United States, to the extent such counsel
deems proper and specified in such opinion, upon the opinion of other counsel of
good standing whom such counsel believes to be reliable and who are satisfactory
to counsel for the Underwriters and (B) as to matters of fact, to the extent
such counsel deems proper, on certificates of responsible officers of Salomon
and public officials. References to the Salomon Prospectus in this paragraph (c)
include any supplements thereto at the Closing Date.

                  (d)    The Representatives shall have received from Cleary,
Gottlieb, Steen & Hamilton, counsel for the Underwriters, such opinion or
opinions, or letter or letters, dated the Closing Date, with respect to the
issuance and sale of the Securities, the Indenture, the Shares, the Salomon
Registration Statement, the Salomon Prospectus (together with any supplement
thereto), certain information contained in the Berkshire Registration Statement
and the Final Berkshire Prospectus (together with any supplement thereto) and
other related matters as the Representatives may reasonably require, and the
Representatives and Berkshire shall have received from Cravath, Swaine & Moore
such letter or letters, dated the Closing Date, with respect to certain
information contained in the Berkshire Registration Statement and the Final
Berkshire Prospectus (together with any supplement thereto) as the
Representatives may reasonably require.

                  (e)    Berkshire shall have furnished to the Representatives a
certificate of Berkshire, signed by the Chairman or the Vice Chairman of the
Board and the principal financial or accounting officer of Berkshire, dated the
Closing Date, to the effect that the signers of such certificate have carefully
examined the Berkshire Registration Statement, the Final Berkshire Prospectus,
any supplement to the Final Berkshire Prospectus and this Agreement and that:

                  (i)    the representations and warranties of Berkshire in this
         Agreement are true and correct in all material respects on and as of
         the Closing Date with the same effect as if 

  
                                       16

         made on the Closing Date and Berkshire has complied with all the
         agreements and satisfied all the conditions on its part to be performed
         or satisfied at or prior to the Closing Date;

                  (ii)  no stop order suspending the effectiveness of the
         Berkshire Registration Statement has been issued and no proceedings for
         that purpose have been instituted or, to Berkshire's knowledge,
         threatened; and

                  (iii) since the date of the most recent financial statements
         included in, or incorporated by reference in, the Final Berkshire
         Prospectus (exclusive of any supplement thereto), there has been no
         material adverse change in the condition (financial or other),
         earnings, business or properties of Berkshire and its subsidiaries,
         whether or not arising from transactions in the ordinary course of
         business, except as set forth in or contemplated in the Final Berkshire
         Prospectus (exclusive of any supplement thereto).

                  (f)   Salomon shall have furnished to the Representatives and
Berkshire a certificate of Salomon, signed by the Senior Vice President and
Controller of Salomon, dated the Closing Date, to the effect that the signers of
such certificate have carefully examined the Salomon Registration Statement, the
Salomon Prospectus, any supplements to the Salomon Prospectus and this Agreement
and that:

                  (i)   the representations and warranties of Salomon in this
         Agreement are true and correct in all material respects on and as of
         the Closing Date with the same effect as if made on the Closing Date
         and Salomon has complied with all the agreements and satisfied all the

         set forth in or contemplated in the Salomon Prospectus (exclusive of
         any supplement thereto).

                  (g)   At the Execution Time and at the Closing Date, Deloitte 
& Touche LLP shall have furnished to the Representatives a letter or letters
(which may refer to letters previously delivered to one or more of the
Representatives), dated respectively as of the Execution Time and as of the
Closing Date, in form and substance satisfactory to the Representatives,
confirming that they are independent accountants within the meaning of the Act
and the Exchange Act and the respective applicable published rules and

<PAGE>   18
                 (i)    in their opinion the audited consolidated financial
         statements and financial statement schedules included or incorporated
         in the Berkshire Registration Statement and the Final Berkshire

         respects with the applicable accounting requirements of the Act and the
         Exchange Act and the related published rules and regulations;

                  (ii)  on the basis of a reading of the latest unaudited
         consolidated financial statements made available by Berkshire and its
         subsidiaries; carrying out certain specified procedures (but not an
         examination in accordance with generally accepted auditing standards)
         which would not necessarily reveal matters of significance with respect
         to the comments set forth in such letter; a reading of the minutes of
         the meetings of the stockholders, directors and audit committees of
         Berkshire and the minutes of the meetings of the stockholders and
         directors of the Subsidiaries; and inquiries of certain officials of
         Berkshire who have responsibility for financial and accounting matters
         of Berkshire and its subsidiaries as to transactions and events
         subsequent to the date of the most recent audited financial statements
         in or incorporated in the Final Berkshire Prospectus, nothing came to
         their attention which caused them to believe that:

                           (1) any unaudited financial statements included or
                  incorporated in the Berkshire Registration Statement and the
                  Final Berkshire Prospectus do not comply as to form in all
                  material respects with applicable accounting requirements and
                  with the published rules and regulations of the Commission
                  with respect to financial statements included or incorporated
                  in quarterly reports on Form 10-Q under the Exchange Act; and
                  said unaudited financial statements are not in conformity with
                  generally accepted accounting principles applied on a basis
                  substantially consistent with that of the audited financial
                  statements included or incorporated in the Berkshire
                  Registration Statement and the Final Berkshire Prospectus; or

                           (2) with respect to the period subsequent to the date
                  of the most recent financial statements (other than any
                  capsule information), audited or unaudited, in or incorporated
                  in the Berkshire Registration Statement and the Final
                  Berkshire Prospectus, there were any increases, at a specified
                  date not more than three business days prior to the date of
                  the letter, in the borrowings under investment agreements and
                  other debt of Berkshire and its subsidiaries or decreases in
                  stockholders' equity of Berkshire, each as compared with the
                  amounts shown on the most recent consolidated balance sheet
                  included or incorporated in the Berkshire Registration
                  Statement and the Final Berkshire Prospectus, except in all
                  instances for changes set forth in such letter, in which case
                  the letter shall be accompanied by an explanation by Berkshire
                  as to the significance thereof unless said explanation is not
                  deemed necessary by the Representatives; and

                  (iii) they have performed certain other specified procedures
         as a result of which they determined that certain information of an
         accounting, financial or statistical nature (which is limited to
         accounting, financial or statistical information derived from the

         Statement and the Final Berkshire Prospectus, agrees with the
         accounting records of Berkshire and its subsidiaries, excluding any
         questions of legal interpretation.

                  References to the Final Berkshire Prospectus in this paragraph
(g) include any supplement thereto at the date of the letter.

                  (h)  At the Execution Time, Arthur Andersen LLP shall have
furnished to the Representatives and Berkshire a letter or letters (which may
refer to letters previously delivered to the Representatives), dated as of the
Execution Time, in form and substance satisfactory to the Representatives,
confirming that they are independent accountants within the meaning of the Act

                  (i)  in their opinion the audited financial statements and
         schedules included or incorporated by reference in the Salomon
         Registration Statement and the Salomon Prospectus comply as to form in
         all material respects with the applicable accounting requirements of
         the Act and the Exchange Act and the related published rules and
         regulations thereunder;

                  (ii) on the basis of a reading of the latest unaudited
         financial statements made available by Salomon and its subsidiaries;
         their limited review in accordance with standards established by the
         American Institute of Certified Public Accountants of the unaudited
         interim financial information as indicated in their reports
         incorporated in the Salomon Registration Statement and the Salomon
         Prospectus; carrying out certain specified procedures (but not an
         examination in accordance with generally accepted auditing standards)
         which would not necessarily reveal matters of significance with respect
         to the comments set forth in such letter; a reading of the minutes of
         the meetings of the stockholders, directors and executive and audit
         committees of Salomon and SBI; and inquiries of certain officials of
         Salomon who have responsibility for financial and accounting matters of
         Salomon and its subsidiaries as to transactions and events subsequent
         to the date of the most recent audited financial statements in or

                  Salomon Prospectus do not comply as to form in all material
                  respects with the applicable accounting requirements of the

                  in conformity with generally accepted accounting principles
                  applied on a basis substantially consistent with that of the
                  audited financial statements included or incorporated in the
                  Salomon Registration Statement and the Salomon Prospectus; or

                           (2) with respect to the period subsequent to the date

                  more than three business days prior to the date of the letter,
                  in the consolidated long-term debt of Salomon and its
                  subsidiaries or decreases in the stockholders' equity of
                  Salomon and its subsidiaries as compared with the amounts

                  the Salomon Registration Statement and the Salomon Prospectus
                  to such specified date there were any decreases, as compared
                  with the corresponding period in the preceding year, in net
                  revenues or income before taxes or in total or per share
                  amounts of net income of Salomon and its subsidiaries, except
                  in all instances for changes or decreases set forth in such
                  letter, in which case the letter shall be accompanied by an
                  explanation by Salomon as to the significance thereof unless
                  said explanation is not deemed necessary by the
                  Representatives; and

                  (iii) they have performed certain other specified procedures

         general accounting records of Salomon and is subsidiaries) set forth in
         the Salomon Registration Statement and the Salomon Prospectus,

         and 11 of Salomon's Annual Report on Form 10-K, incorporated in the

         Salomon Financial Condition and Results of Operations" included or
         incorporated in Salomon's Quarterly Reports on Form 10-Q, incorporated
         in the Salomon Registration Statement and the Salomon Prospectus,
         agrees with the accounting records of Salomon and its subsidiaries,
         excluding any questions of legal interpretation.

include any supplement thereto at the date of the letter.

<PAGE>   21
                  In addition, at the Closing Date, Arthur Andersen LLP shall
have furnished to the Representatives and Berkshire a letter or letters, dated
as of the Closing Date, in form and substance satisfactory to the
Representatives, to the effect set forth above.

                  (i) Subsequent to the Execution Time or, if earlier, the dates
as of which information is given in each of the Berkshire Registration Statement
and the Salomon Registration Statement (exclusive of any amendment thereof) and
each of the Final Berkshire Prospectus and the Salomon Prospectus (exclusive of
any supplements thereto), there shall not have been (i) any change or decrease
specified in the letter or letters referred to in paragraphs (g) and (h) of this
Section 8 or (ii) any change, or any development involving a prospective change,
in or affecting the business or properties of either Berkshire or Salomon and
their respective subsidiaries, taken as a whole, the effect of which, in any
case referred to in clause (i) or (ii) above, is, in the judgment of the
Representatives, so material and adverse as to make it impractical or
inadvisable to proceed with the offering or delivery of the Securities as
contemplated by the Berkshire Registration Statement and the Salomon
Registration Statement (in either case, exclusive of any amendment thereof) and
the Final Berkshire Prospectus and the Salomon Prospectus (in either case,
exclusive of any supplement thereto).

                  (j) Subsequent to the Execution Time, there shall not have
been any decrease in the rating of any of Berkshire's or Salomon's debt
securities by any "nationally recognized statistical rating organization" (as
defined for purposes of Rule 436(g) under the Act).

                  (k) Prior to the Closing Date, each of Berkshire and Salomon
shall have furnished to the Representatives such further information,
certificates and documents as the Representatives may reasonably request.

                  If any of the conditions specified in this Section 8 shall not
have been fulfilled in all material respects when and as provided in this
Agreement, or if any of the opinions and certificates mentioned above or
elsewhere in this Agreement shall not be in all material respects reasonably
satisfactory in form and substance to the Representatives and counsel for the
Underwriters, this Agreement and all obligations of the Underwriter hereunder
may be canceled at, or at any time prior to, the Closing Date by the
Representatives. Notice of such cancellation shall be given to Berkshire and
Salomon in writing or by telephone or telegraph confirmed in writing.

                  9. Reimbursement of Underwriters' Expenses. If the sale of the
Securities provided for herein is not consummated because any condition to the
obligations of the Underwriters set forth in Section 8 hereof is not satisfied,
because of any termination pursuant to Section 12 hereof or because of any
refusal, inability or failure on the part of Berkshire or Salomon to perform any
agreement herein or comply with any provision hereof other than by reason of a
default by any Underwriter, Berkshire will reimburse the Underwriters severally
upon demand for all reasonable out-of-pocket expenses (including reasonable fees
and disbursements of counsel) that shall have been incurred by them in
connection with the proposed purchase and sale of the Securities.

<PAGE>   22
         10. Indemnification and Contribution. (a) Berkshire agrees to indemnify
and hold harmless each Underwriter, the directors, officers, employees and
agents of each Underwriter, each person who controls any Underwriter within the
meaning of either the Act or the Exchange Act, Salomon, each of Salomon's
directors, each of Salomon's officers who signs the Salomon Registration
Statement and each person who controls Salomon within the meaning of either the
Act or the Exchange Act against any and all losses, claims, damages or
liabilities, joint or several, to which they or any of them may become subject
under the Act, the Exchange Act or other Federal or state statutory law or
regulation, at common law or otherwise, insofar as such losses, claims, damages
or liabilities (or actions in respect thereof) arise out of or are based upon
any untrue statement or alleged untrue statement of a material fact contained in
(i) the Berkshire Registration Statement as originally filed or in any amendment
thereof, or in the Basic Berkshire Prospectus, any Preliminary Final Berkshire
Prospectus or the Final Berkshire Prospectus, or in any amendment thereof or
supplement thereto, or (ii) the Salomon Registration Statement as originally
filed or in any amendment thereof, or in any Preliminary Salomon Prospectus or
the Salomon Prospectus, or in any amendment thereof or supplement thereto, or
arise out of or are based upon the omission or alleged omission to state in the
documents referred to in clause (i) or (ii) above a material fact required to be
stated in the documents referred to in clause (i) or (ii) above or necessary to
make the statements therein not misleading, and agrees to reimburse each such
indemnified party, as incurred, for any legal or other expenses reasonably
incurred by them in connection with investigating or defending any such loss,
claim, damage, liability or action; provided, however, that Berkshire will not
be liable under the indemnity agreement in this paragraph (a) to the extent that
any such loss, claim, damage or liability arises out of or is based upon any
such untrue statement or alleged untrue statement or omission or alleged
omission made in (A) the documents referred to in clause (i) or (ii) above in
reliance upon and in conformity with written information furnished to Berkshire
or Salomon by or on behalf of any Underwriter through the Representatives
specifically for inclusion therein, or (B) (1) the Berkshire Registration
Statement, any Preliminary Final Berkshire Prospectus or the Final Berkshire
Prospectus (or any amendment or supplement thereto) under the headings "Salomon
Inc" and "Price Range of Salomon Common Stock and Dividend Policy" (other than
the last paragraph thereof) or (2) the Salomon Registration Statement, any
Preliminary Salomon Prospectus or the Salomon Prospectus (or any amendment or
supplement thereto), except under the heading "Ownership of Company Securities
by Berkshire". This indemnity agreement will be in addition to any liability
which Berkshire may otherwise have.

         (b) Salomon agrees to indemnify and hold harmless each Underwriter, the
directors, officers, employees and agents of each Underwriter, each person who
controls any Underwriter within the meaning of either the Act or the Exchange
Act, Berkshire, each of Berkshire's directors, each of Berkshire's officers who
signs the Berkshire Registration Statement, and each person who controls
Berkshire within the meaning of either the Act or the Exchange Act, against any
and all losses, claims, damages or liabilities, joint or several, to which they
or any of them may become subject under the Act, the Exchange Act or other
Federal or state statutory law or regulation, at common law or otherwise,
insofar as such losses, claims, damages or liabilities (or actions in respect
thereof) arise out of or are based upon any untrue statement or alleged untrue
statement of a material fact contained in (i) the Salomon Registration Statement
as originally filed or in any amendment thereof, or in any Preliminary Salomon


                                       22


<PAGE>   23
Prospectus or the Salomon Prospectus, or in any amendment thereof or supplement
thereto, or (ii) the Berkshire Registration Statement as originally filed or in
any amendment thereof, or in any Preliminary Final Berkshire Prospectus or the
Final Berkshire Prospectus, or in any amendment thereto or supplement thereto,
or arise out of or are based upon the omission or alleged omission to state in
the documents referred to in clause (i) or (ii) above a material fact required
to be stated in the documents referred to in clause (i) or (ii) above or
necessary to make the statements therein not misleading, and agrees to reimburse
each such indemnified party, as incurred, for any legal or other expenses
reasonably incurred by them in connection with investigating or defending any
such loss, claim, damage, liability or action; provided, however, that Salomon
will not be liable under the indemnity agreement in this paragraph (b) to the
extent that any such loss, claim, damage or liability arises out of or is based
upon any such untrue statement or alleged untrue statement or omission or
alleged omission made in (A) the documents referred to in clause (i) or (ii)
above in reliance upon and in conformity with written information furnished to
Salomon or Berkshire by or on behalf of any Underwriter through the
Representatives specifically for inclusion therein or (B) (1) the information
contained in or omitted from the Salomon Registration Statement, any Preliminary
Salomon Prospectus or the Salomon Prospectus under the heading "Ownership of
Company Securities by Berkshire" in the prospectus supplement and in the first,
fourth and fifth paragraphs under the heading "Ownership of Company Securities
by Berkshire" in the base prospectus or (2) the Berkshire Registration
Statement, any Preliminary Final Berkshire Prospectus or the Final Berkshire
Prospectus (or any amendment or supplement thereto), except under the headings
"Salomon Inc" and "Price Range of Salomon Common Stock and Dividend Policy"
(other than the last paragraph thereof). This indemnity agreement will be in
addition to any liability which Salomon may otherwise have.

                  (c) Each Underwriter severally agrees to indemnify and hold
harmless Berkshire and Salomon, each of their respective directors, each of
their respective officers who signs the Berkshire Registration Statement or the
Salomon Registration Statement, respectively, and each person who controls
Berkshire or Salomon within the meaning of either the Act or the Exchange Act,
to the same extent as the foregoing indemnities in paragraph (a) from Berkshire
to each Underwriter or in paragraph (b) from Salomon to each Underwriter,
respectively, but only with reference to written information relating to such
Underwriter furnished to Berkshire by or on behalf of such Underwriter through
the Representatives specifically for inclusion in the Berkshire Registration
Statement as originally filed or in any amendment thereof, or in any Preliminary
Final Berkshire Prospectus or the Final Berkshire Prospectus, or in any
amendment thereof or supplement thereto, and to Salomon by or on behalf of any
Underwriter through the Representatives specifically for inclusion in the
Salomon Registration Statement as originally filed or in any amendment thereof,
or in any Preliminary Salomon Prospectus or the Salomon Prospectus, or in any
amendment thereof or supplement thereto. This indemnity agreement will be in
addition to any liability which any Underwriter may otherwise have. Berkshire
and Salomon acknowledge that the statements set forth in the last paragraph of
the cover page and under the heading "Plan of Distribution" in any Preliminary
Final Berkshire Prospectus or the Final Berkshire Prospectus and the statements
set forth under the heading "Plan of Distribution" in any Preliminary Salomon
Prospectus or the Salomon Prospectus constitute the only information furnished
in writing by or on behalf of any Underwriter for inclusion in the 


                                       23


<PAGE>   24
documents referred to in the foregoing indemnity, and you, as the
Representatives, confirm that such statements are correct.

                  (d) Promptly after receipt by an indemnified party under this
Section 10 of notice of the commencement of any action, such indemnified party
will, if a claim in respect thereof is to be made against the indemnifying party
under this Section 10, notify the indemnifying party in writing of the
commencement thereof; but the failure so to notify the indemnifying party (i)
will not relieve it from any liability under paragraphs (a), (b) or (c) above
unless and to the extent it did not otherwise learn of such action and such
failure results in the forfeiture by the indemnifying party of substantial
rights and defenses and (ii) will not, in any event, relieve the indemnifying
party from any obligations to any indemnified party other than the
indemnification obligation provided in paragraphs (a), (b) or (c) above. The
indemnifying party shall be entitled to appoint counsel of indemnifying party's
choice at the indemnifying party's expense to represent the indemnified party in
any action for which indemnification is sought (in which case the indemnifying
party shall not thereafter be responsible for the fees and expenses of any
separate counsel retained by the indemnified party or parties except as set
forth below); provided, however, that such counsel shall be satisfactory to the
indemnified party. Notwithstanding the indemnifying party's election to appoint
counsel to represent the indemnified party in an action, the indemnified party
shall have the right to employ separate counsel (including local counsel), and
the indemnifying party shall bear the reasonable fees, costs and expenses of
such separate counsel if (i) the use of counsel chosen by the indemnifying party
to represent the indemnified party would present such counsel with a conflict of
interest, (ii) the actual or potential defendants in, or targets of, any such
action include both the indemnified party and the indemnifying party and the
indemnified party shall have reasonably concluded that there may be legal
defenses available to it and/or other indemnified parties which are different
from or additional to those available to the indemnifying party, (iii) the
indemnifying party shall not have employed counsel satisfactory to the
indemnified party to represent the indemnified party in accordance with this
paragraph (d) within a reasonable time after notice of the institution of such
action or (iv) the indemnifying party shall authorize the indemnified party to
employ separate counsel at the expense of the indemnifying party. An
indemnifying party will not, without the prior written consent of the
indemnified parties, settle or compromise or consent to the entry of any
judgment with respect to any pending or threatened claim, action, suit or
proceeding in respect of which indemnification or contribution may be sought
hereunder (whether or not the indemnified parties are actual or potential
parties to such claim or action) unless such settlement, compromise or consent
includes an unconditional release of each indemnified party from all liability
arising out of such claim, action, suit or proceeding.

                  (e) In the event that the indemnity provided in paragraph (a),
(b) or (c) of this Section 10 is unavailable to or insufficient to hold harmless
an indemnified party for any reason, Berkshire, Salomon and the Underwriters
agree to contribute to the aggregate losses, claims, damages and liabilities
(including legal or other expenses reasonably incurred in connection with
investigating or defending same) (collectively "Losses") to which Berkshire,
Salomon and one or more of the Underwriters may be subject in such proportion as
is appropriate to reflect the relative benefits received by Berkshire and
Salomon, on the one hand, and the Underwriters, on the other hand, from the
offering of the Securities; provided, however, that in no case shall any


                                       24



<PAGE>   25
Underwriter (except as may be provided in any agreement among underwriters
relating to the offering of the Securities) be responsible for any amount in
excess of the underwriting discount or commission applicable to the Securities
purchased by such Underwriter hereunder. If the allocation provided by the
immediately preceding sentence is unavailable for any reason, Berkshire and
Salomon, on the one hand, and the Underwriters, on the other hand, shall
contribute in such proportion as is appropriate to reflect not only such
relative benefits but also the relative fault of Berkshire and Salomon, on the
one hand, and the Underwriters, on the other hand, in connection with the
statements or omissions which resulted in such Losses as well as any other
relevant equitable considerations. The relative benefits received by Berkshire
or Salomon on the one hand and the Underwriters on the other with respect to
such offering shall be deemed to be equal to the total net proceeds from the
offering (before deducting expenses) received by Berkshire, and the total
underwriting discounts and commissions, respectively, in each case as set forth
on the cover page of the Final Berkshire Prospectus. Relative fault shall be
determined by reference to whether any alleged untrue statement or omission
relates to information provided by Berkshire and Salomon, on the one hand, or
the Underwriters, on the other hand. Berkshire, Salomon and the Underwriters
agree that it would not be just and equitable if contribution were determined by
pro rata allocation or any other method of allocation which does not take
account of the equitable considerations referred to above. Notwithstanding the
provisions of this paragraph (e), no person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Act) shall be
entitled to contribution from any person who was not guilty of such fraudulent
misrepresentation. For purposes of this Section 10, each person who controls an
Underwriter within the meaning of either the Act or the Exchange Act and each
director, officer, employee and agent of such Underwriter shall have the same
rights to contribution as such Underwriter, and each person who controls
Berkshire or Salomon within the meaning of either the Act or the Exchange Act,
each officer of Berkshire or Salomon who shall have signed the Berkshire
Registration Statement or the Salomon Registration Statement and each director
of Berkshire or Salomon shall have the same rights to contribution as Berkshire
or Salomon, subject in each case to the applicable terms and conditions of this
paragraph (e).

                  11. Default by an Underwriter. If any one or more Underwriters
shall fail to purchase and pay for any of the Securities agreed to be purchased
by such Underwriter or Underwriters hereunder and such failure to purchase shall
constitute a default in the performance of its or their obligations under this
Agreement, the remaining Underwriters shall be obligated severally to take up
and pay for (in the respective proportions which the principal amount of
Securities set forth opposite their names in Schedule I hereto bears to the
aggregate principal amount of Securities set forth opposite the names of all the
remaining Underwriters) the Securities which the defaulting Underwriter or
Underwriters agreed but failed to purchase; provided, however, that in the event
that the aggregate principal amount of Securities which the defaulting
Underwriter or Underwriters agreed but failed to purchase shall exceed 10% of
the aggregate amount of Securities set forth in Schedule I hereto, the remaining
Underwriters shall have the right to purchase all, but shall not be under any

         WHEREAS the Company entered into an Indenture dated as of December 1,
1987 (the "Basic Indenture") with The First National Bank of Boston, as the

         SECTION 1. The Basic Indenture is hereby amended to reflect certain
amendments to the Trust Indenture Act as follows:

         (a) The definition of "Trust Indenture Act" in Section 101 is amended

Act of 1990," after the date "1939" in the first line of such definition.

         (c) Section 107 of the Indenture is amended to read in its entirety as
follows:

                  "If any provision hereof limits, qualifies or conflicts with a
         provision of the Trust Indenture Act which is required under such Act
         to be a part of and govern this Indenture, the latter provision shall
         control. If any provision of this Indenture modifies or excludes any
         provision of the Trust Indenture Act which may be so modified or
         excluded, the latter provision shall be deemed to apply to this
         Indenture as so modified or to be excluded, as the case may be."

         provided by, and subject to the provisions of, the Trust Indenture Act
         and this Indenture. To the extent permitted by such Act, the Trustee
         shall not be deemed to have a conflicting interest by virtue of being a
         trustee under this Indenture with respect to Securities of more than
         one series."

         (e) Section 609 of the Indenture is amended to read in its entirety as
follows:

                  "There shall at all times be one (and only one) Trustee
         hereunder with respect to the Securities of each series, which may be
         Trustee hereunder for Securities of one or more other series. Each
         Trustee shall be a Person that is eligible pursuant to the Trust
         Indenture Act to act as such and has a combined capital and surplus of
         at least $50,000,000. If any such Person publishes reports of condition
         at least annually, pursuant to law or to the requirements of its
         supervising or examining authority, then for the purposes of this
         Section and to the extent permitted by the Trust Indenture Act, the
         combined capital and surplus of such Person shall be deemed to be its
         combined capital and surplus as set forth in its most recent report of
         condition so published. If at any time the Trustee with respect to the
         Securities of any series shall cease to be eligible in accordance with
         the provisions of this Section, it shall resign immediately in the
         manner and with the effect hereinafter specified in this Article."

follows:

                  "If and when the Trustee shall be or become a creditor of the
         Company (or any other obligor upon the Securities), the Trustee shall
         be subject to the provisions of the Trust Indenture Act regarding the
         collection of claims against the Company (or any such other obligor)."

         (f) Section 703 of the Indenture is amended to read in its entirety as
follows:

                  "The Trustee shall transmit to Holders such reports concerning
         the Trustee and its actions under this Indenture as may be required
         pursuant to the Trust Indenture Act at the times and in the manner
         provided pursuant thereto.

                  A copy of each such report shall, at the time of such
         transmission to Holders, be filed by the Trustee with each stock
         exchange upon which any Debt Securities are listed, with the Commission
         and with the Company. The Company will notify the Trustee when any Debt
         Securities are listed on any stock exchange."

         (g) Section 1004 of the Indenture is amended by denoting the current
paragraph in Section 1004 as paragraph (a) and by adding as a new paragraph (b)
the following:

                  "(b) The Company will deliver to the Trustee, within 120 days

         hereof, a certificate of the principal executive officer, principal
         financial officer or principal accounting officer of the Company
         stating whether or not to the best knowledge of the signer thereof the
         Company is in default in the performance and observance of any of the

         if the Company shall be in default, specifying all such defaults and

Common Stock at Maturity, if at Maturity both (A) the 10-Day Average Closing
Price of Salomon Common Stock and (B) the Closing Price of Salomon Common Stock
on the last Trading Day prior to Maturity are equal to or greater than the
Exchange Price then in effect. The Salomon Common Stock, if any, to which a
Holder is entitled upon any exchange at Maturity will be delivered or made
available by the Company as soon as practicable and, in any event, not later
than the close of business on the fifth Business Day after Maturity. If the
Company delivers shares of Salomon Common Stock at Maturity, Holders of the
Notes will be responsible for the payment of any brokerage costs incurred upon
any subsequent sale of such stock.

SECTION 1402.  Exchange at Option of Holder.

         (a) On each Exchange Date, any Notes (other than Notes with respect to
which a notice of exchange for Salomon Common Stock has been delivered by the
Company prior to such Exchange Date) will be exchangeable, at the option of the
Holder, for shares of Salomon Common Stock at the Exchange Rate then in effect,
provided that the Closing Price of Salomon Common Stock on the Exchange Date
exceeds the Exchange Price then in effect, and subject to certain additional
conditions described below.

         (b) To exchange a Note for Salomon Common Stock, a Holder must, at any
time during the relevant Exchange Period, (1) deliver to the Trustee (or such
office or agency that may be established by the Company for such purpose) a
completed and manually signed exchange notice (the "Exchange Notice") on the
back of such Note (or a facsimile thereof),
<PAGE>   9
                                        8


(2) surrender or arrange for book entry transfer of such Note to the Trustee,
(3) if required, furnish appropriate endorsements and transfer documents and (4)
if required, pay all transfer or similar taxes. Any Exchange Notice may be
withdrawn by the Holder by a written notice of withdrawal delivered to the
Trustee prior to the close of business on the Exchange Date. The notice of
withdrawal shall state the principal amount due at Maturity and any certificate
number(s) of the Notes as to which the withdrawal notice relates and the
principal amount due at Maturity, if any, which remains subject to the Exchange
Notice, each of which must be $1,000 or an integral multiple thereof.

         (c) In the event that a Salomon Prospectus is required to be delivered
under the Securities Act of 1933 upon an exchange of Notes and is not made
available by Salomon to the Company for use during any Exchange Period, the
Company shall, on or prior to the applicable Exchange Date, upon written notice
to each Holder that has complied with the procedures for exchange of Notes
described herein (an "Electing Holder"), postpone such Exchange Date from time
to time until such later Business Day (the "New Exchange Date") as the Company
is able to deliver a Salomon Prospectus or is no longer required to do so. In
the event that the Company postpones any Exchange Date, (1) no additional Notes
may be delivered to the Trustee by any Holder for exchange into Salomon Common
Stock at any time during the period from the original Exchange Date through and
including the New Exchange Date, (2) each Electing Holder shall have the right,
at any time until the New Exchange Date, to irrevocably withdraw any Notes
delivered to the Trustee on or prior to the original Exchange Date, and (3) any
Notes that have not been withdrawn by an Electing Holder prior to the New
Exchange Date shall be exchanged for shares of Salomon Common Stock on the New
Exchange Date, provided that the Closing Price of Salomon Common Stock on the
New Exchange Date exceeds the Exchange Price then in effect.

         (d) If a Reorganization Event shall have occurred, the Notes shall not
be exchangeable at the option of the Holder for any Exchange Securities during
any Exchange Period if a prospectus covering such Exchange Securities is
required to be delivered by the Company under the Securities Act and is not
available to the Company for use during such Exchange Period.

         (e) Upon any exchange of Notes at the option of the Holder, no payment
will be made in respect of accrued but unpaid interest, unless such exchange is
made concurrently with or after acceleration of the Notes following an event of
default hereunder. The Salomon Common Stock to which a Holder is entitled upon
any exchange will be delivered or made available by the Company as soon as
practicable and, in any event, not later than the close of business on the fifth
Business Day after the applicable Exchange Date.

SECTION 1403.  Redemption or Exchange at Option of the Company.
<PAGE>   10
                                        9


         (a) The Notes will not be redeemable or exchangeable at the option of
the Company prior to [_________], 1999. Thereafter, (1) at any time when both
(A) the 10-Day Average Closing Price of Salomon Common Stock on the date on
which the applicable notice of redemption is given and (B) the Closing Price of
Salomon Common Stock on the last Trading Day prior to such date are equal to or
greater than the Exchange Price then in effect, the Company may, at its option,
either (i) exchange the Notes, in whole or in part, for shares of Salomon Common
Stock at the Exchange Rate then in effect or (ii) redeem the Notes, in whole or
in part, in cash at a price per Note equal to the product of the Exchange Rate
then in effect and the Current Market Value of Salomon Common Stock on the date
on which the applicable notice of redemption is given, and (2) at any other
time, the Company may, at its option redeem the Notes, in whole or in part, in
cash at a price per Note equal to the Accreted Value of the Notes on the date of
redemption. However, the Company may not give any notice of redemption for cash
(x) during the period from the beginning of any Exchange Period until the close
of business on the applicable Exchange Date or New Exchange Date or (y) prior to
the beginning of any Exchange Period if the Redemption Date would occur during
or after such Exchange Period. Upon any exchange or redemption described in
clause (1) above, the Holders of Notes will not receive any payment representing
accrued OID; such accrued OID will be deemed paid upon the receipt of Salomon
Common Stock or the cash equivalent received on such exchange or redemption.

         (b) In connection with any redemption or exchange prior to Maturity of
the Notes, the Company will notify the Depositary and the Trustee and will
publish a notice in a daily newspaper of national circulation stating (1) the
Exchange Rate then in effect, (2) whether the Notes will be exchanged for shares
of Salomon Common Stock or redeemed for cash, (3) the redemption or Exchange
Date (which shall be at least 15 days but not more than 30 days after the date
of such notice) and (4) in the case of a redemption, the redemption price. On
the Exchange Date with respect to any exchange of Notes for Salomon Common
Stock, such Notes shall cease to be outstanding and shall be deemed to represent
solely the right to receive shares of Salomon Common Stock in accordance with
the terms of the Indenture. The Company will pay in cash the accrued and unpaid
interest on all Notes redeemed or exchanged to but excluding the date of
redemption or exchange. If the Company exchanges Notes for shares of Salomon
Common Stock, Holders of the Notes will be responsible for the payment of any
brokerage costs incurred upon the subsequent sale of such shares.

         (c) If less than all the Notes then outstanding are to be redeemed or
exchanged prior to maturity of the Notes, the Trustee will select those to be
redeemed or exchanged as a whole or in part pro rata or by lot or by such method
as the Trustee shall deem fair and appropriate. Notice of redemption or exchange
will be given to Holders of the Notes to be redeemed or exchanged by first-class
mail, postage prepaid at their last address appearing on the Note registry
books.

SECTION 1404.  No Fractional Shares.
<PAGE>   11
                                       10


         No fractional shares of Salomon Common Stock will be issued if any
Notes are exchanged for shares of Salomon Common Stock at or prior to Maturity.
If more than one Note from the same Holder is exchanged for Salomon Common Stock
at one time, the number of full shares of Salomon Common Stock to be delivered
upon exchange shall be computed on the basis of the aggregate number of Notes
from such Holder so exchanged at that time. In lieu of any fractional share
otherwise issuable in respect of all Notes of any Holder that are exchanged at
or prior to Maturity, the Company, through the Paying Agent, shall make a cash
payment in respect of such fractional interest to such Holder in an amount equal
to the product of such fraction of a share and the Current Market Value of
Salomon Common Stock on the applicable Exchange Date (in the case of an exchange
at the option of the Holder), the date on which the related notice of exchange
is given (in the case of an exchange at the option of the Company) or at
Maturity, as applicable. The Company shall, upon exchange of any Notes, provide
cash to the Paying Agent in an amount equal to the cash payable with respect to
any fractional shares of Salomon Common Stock deliverable upon exchange of such
Notes, and the Company shall retain such fractional shares of Salomon Common
Stock.

SECTION 1405.  Adjustment of Exchange Rate.

         (a) Adjustment for Distributions, Reclassification, etc. The Exchange
Rate shall be subject to adjustment from time to time as follows:

                  (1)  If Salomon shall:

                            (A) pay a dividend or make a distribution with
                  respect to the Salomon Common Stock in shares of such stock;

                            (B) subdivide or split the outstanding shares of
                  Salomon Common Stock into a greater number of shares;

                            (C) combine the outstanding shares of Salomon Common
                  Stock into a smaller number of shares; or

                            (D) issue by reclassification of shares of Salomon
                  Common Stock any shares of common stock of Salomon;

          then, in any such event, the Exchange Rate in effect immediately prior
          to such event shall be adjusted so that the Holder of any Note shall
          thereafter be entitled to receive, upon exchange of such Holder's Note
          by the Company at Maturity or upon redemption, the number of shares of
          Salomon Common Stock that such Holder would have owned or been
          entitled to receive immediately following such event had such Note
          been exchanged immediately prior to such event or any record date with
          respect thereto. Each such adjustment shall become effective at the
          opening of business on
<PAGE>   12
                                       11


          the Business Day next following the record date for determination of
          holders of Salomon Common Stock entitled to receive such dividend or
          distribution in the case of a dividend or distribution and shall
          become effective immediately after the effective date in the case of a
          subdivision, split, combination or reclassification. Each such 
          adjustment shall be made successively.

                  (2) If Salomon shall issue rights or warrants to all holders
          of Salomon Common Stock entitling them to subscribe for or purchase
          shares of Salomon Common Stock (other than rights to purchase Salomon
          Common Stock pursuant to (A) a plan for the reinvestment of dividends
          or interest or (B) pursuant to a shareholders rights plan or
          agreement, unless a triggering event shall have occurred thereunder)
          at a price per share less than the current market price of Salomon
          Common Stock (determined for purposes of this clause (2) as the
          Closing Price per share of Salomon Common Stock on the record date
          fixed for the determination of stockholders entitled to receive such
          rights or warrants), then in each case the Exchange Rate shall be
          adjusted by multiplying the Exchange Rate in effect immediately prior
          to such record date, by a fraction, of which (x) the numerator shall
          be the number of shares of Salomon Common Stock outstanding at the
          close of business on such record date, plus the number of additional
          shares of Salomon Common Stock offered for subscription or purchase
          pursuant to such rights or warrants, and (y) the denominator shall be
          the number of shares of Salomon Common Stock outstanding at the close
          of business on such record date, plus the number of additional shares
          of Salomon Common Stock that the aggregate offering price of the total
          number of shares of Salomon Common Stock so offered for subscription
          or purchase pursuant to such rights or warrants would purchase at such
          current market price (calculated at the Closing Price per share of
          Salomon Common Stock on such record date), which shall be determined
          by multiplying such total numbers of shares offered by the exercise
          price of such rights or warrants and dividing the product so obtained
          by such current market price. Such adjustment shall become effective
          at the opening of business on the Business Day next following the
          record date for the determination of stockholders entitled to receive
          such rights or warrants. To the extent that shares of Salomon Common
          Stock are not delivered after the expiration of such rights or
          warrants, the Exchange Rate shall be readjusted to the Exchange Rate
          which would then be in effect had such adjustments for the issuance of
          such rights or warrants been made upon the basis of delivery of only
          the number of shares of Salomon Common Stock actually delivered. Each
          such adjustment shall be made successively.

                  (3) If Salomon shall pay a dividend or make a distribution to
          all holders of Salomon Common Stock of any class of its capital stock,
          evidences of its indebtedness or other assets (in each case excluding
          any dividends or distributions referred to in paragraph (1) above or
          any ordinary periodic cash dividends that do not constitute
          Extraordinary Cash Dividends (as defined below)) or shall issue to all
<PAGE>   13
                                       12


          holders of Salomon Common Stock rights or warrants to subscribe for or
          purchase any of its securities (other than those referred to in
          paragraph (2) above), then in each such case, the Exchange Rate shall
          be adjusted by multiplying the Exchange Rate in effect on the record
          date mentioned below by a fraction of which (A) the numerator shall be
          the current market price per share of the Salomon Common Stock on the
          record date for the determination of stockholders entitled to receive
          such dividend or distribution (such current market price being
          determined for purposes of this paragraph as the Closing Price per
          share of Salomon Common Stock on such record date) and (B) the
          denominator shall be such current market price per share of Salomon
          Common Stock less the fair market value (as determined by the Board of
          Directors of the Company, whose determination shall be conclusive, and
          described in a resolution adopted with respect thereto) as of such
          record date of the portion of the capital stock, evidences of
          indebtedness or other assets so distributed or of such subscription
          rights or warrants applicable to one share of Salomon Common Stock;
          provided, however, that in the event of a distribution of shares of
          capital stock of a subsidiary of Salomon (a "Spin-Off") made to
          holders of shares of Salomon Common Stock, the numerator of such
          fraction shall be the sum of (i) the Closing Price of Salomon Common
          Stock as of the 35th Trading Day after the effective date of such
          Spin-Off and (ii) the Closing Price of the number of shares (or the
          fraction of a share) of capital stock of such subsidiary of Salomon on
          such 35th Trading Day which is distributed in such Spin-Off in respect
          of one share of Salomon Common Stock as of such 35th Trading Day and
          the denominator of which shall be the Closing Price of Salomon Common
          Stock as of such 35th Trading Day. Each such adjustment shall become
          effective on the opening of business on the Business Day next
          following the record date for the determination of stockholders
          entitled to receive such dividend or distribution (or, in the case of
          an adjustment pursuant to the proviso of the immediately preceding
          sentence, on the Business Day next following the 35th Trading Day
          after the effective date of the Spin-Off). Each such adjustment shall
          be made successively.

                  (4) Any shares of Salomon Common Stock issuable in payment of
          a dividend shall be deemed to have been issued immediately prior to
          the close of business on the record date for such dividend for
          purposes of calculating the number of outstanding shares of Salomon
          Common Stock under paragraph (2) above.

                  (5) All adjustments to the Exchange Rate shall be calculated
          to the nearest 1/10,000th of a share of Salomon Common Stock (or if
          there is not a nearest 1/10,000th of a share to the next lower
          1/10,000th of a share). No adjustment in the Exchange Rate shall be
          required unless such adjustment would require an increase or decrease
          of at least one percent therein; provided, however, that any
          adjustments which by reason of this paragraph are not required to be
          made shall be carried forward and taken into account in any subsequent
          adjustment.
<PAGE>   14
                                       13


                  (6) For purposes of the foregoing, the term "Extraordinary
          Cash Dividend" shall mean, with respect to any consecutive 365-day
          period, any cash dividend with respect to Salomon Common Stock the
          amount of which, together with the aggregate amount of all other such
          cash dividends on the Salomon Common Stock occurring in such 365-day
          period, exceeds on a per share basis 10% of the average Closing Price
          per share of the Salomon Common Stock over such 365-day period, and
          for purposes of applying the formula set forth in paragraph (3) above,
          the fair market value of such dividends being calculated pursuant to
          such paragraph (3) shall be equal to (A) the aggregate amount of such
          cash dividend together with the amounts of such other cash dividends
          occurring in such period minus (B) the aggregate amount of such other
          cash dividends occurring in such period for which a prior adjustment
          in the Exchange Rate was previously made as described in this
          subsection. In making the determinations required by the foregoing
          sentence, the amount of cash dividends paid on a per share basis shall
          be appropriately adjusted to reflect the occurrence during such period
          of any event described in this subsection.

          (b)  Adjustment of Exchange Consideration for Consolidation, Merger or
Other Reorganization Event.

          (1) In the event of (A) any consolidation or merger of Salomon, or any
surviving entity or subsequent surviving entity of Salomon (a "Salomon
Successor"), with or into another entity (other than a merger or consolidation
in which Salomon is the continuing corporation and in which the Salomon Common
Stock outstanding immediately prior to the merger or consolidation is not
exchanged for cash, securities ("Exchange Securities") or other property of
Salomon or another corporation), (B) any statutory exchange of securities of
Salomon or any Salomon Successor with another corporation (other than in
connection with a merger or acquisition) or (C) any liquidation, dissolution or
winding up of Salomon or any Salomon Successor (any such event, a
"Reorganization Event"), if the Company shall have the right to deliver either
cash or Salomon Common Stock at Maturity or upon redemption or exchange of the
Notes, then, at the option of the Company, each Holder of Notes will receive at
Maturity or upon such redemption or exchange, in lieu of Salomon Common Stock,
cash in an amount equal to the Exchange Rate multiplied by the Transaction
Value. Notwithstanding the foregoing, with respect to any securities received in
a Reorganization Event that (i) are (a) listed on a United States national
securities exchange, (b) reported on a United States national securities system
subject to last sale reporting, (c) traded in the over-the-counter market and
reported on the National Quotation Bureau or similar organization or (d) for
which bid and ask prices are available from at least three nationally recognized
investment banking firms and (ii) are either (x) perpetual equity securities or
(y) non-perpetual equity or debt securities with a stated maturity after the
Maturity Date ("Reported Exchange Securities"), the Company may, at its option,
in lieu of delivering the amount of cash deliverable in respect of Reported
Exchange Securities received in a Reorganization Event, as determined in
accordance with the previous sentence, deliver a number of such Reported
Exchange Securities with a value equal to such cash
<PAGE>   15
                                       14


amount, as determined in accordance with clause (2) of the definition of
Transaction Value, as applicable; provided, however, that (i) if such option is
exercised, the Company shall deliver Reported Exchange Securities in respect of
all, but not less than all, cash amounts that would otherwise be deliverable in
respect of Reported Exchange Securities received in a Reorganization Event, (ii)
the Company may not exercise such option if the Company has elected to deliver
cash in lieu of Salomon Common Stock deliverable at Maturity or upon redemption
and (iii) the Company must exercise such option if the Company does not elect to
deliver cash in lieu of Salomon Common Stock deliverable at Maturity or upon
redemption. If the Company elects to deliver Reported Exchange Securities, each
Holder of Notes will be responsible for the payment of any and all brokerage and
other transaction costs upon the sale of such Reported Exchange Securities. If,
following any Reorganization Event, any Reported Exchange Security ceases to
qualify as a Reported Exchange Security, then (x) the Company may no longer
elect to deliver such Reported Exchange Security in lieu of an equivalent amount
of cash and (y) notwithstanding clause (2) of the definition of Transaction
Value, the Transaction Value of such Reported Exchange Security shall mean the
fair market value of such Reported Exchange Security on the date such security
ceases to qualify as a Reported Exchange Security, as determined by a nationally
recognized investment banking firm selected for this purpose by the Company.

          (2) If a Reorganization Event shall occur, subject to the conditions
described in Section 1402(d), upon exchange of any Notes at the option of the
Holder, each Holder of a Note will have the right to receive the kind and amount
of cash, Exchange Securities or other property receivable upon such
Reorganization Event by a holder of the number of shares of Salomon Common Stock
for which such Note might have been exchanged immediately prior to such
Reorganization Event (assuming that such Holder failed to exercise his rights of
election, if any, as to the kind or amount of cash, Exchange Securities, and
other property receivable in such Reorganization Event). If a Holder elects to
exchange any Notes for Exchange Securities following a Reorganization Event,
such Holder will be responsible for the payment of any and all brokerage and
other transaction costs upon the sale of such Exchange Securities.

          (3) The kind and amount of securities into which the Notes shall be
exchangeable by the Company after consummation of any Reorganization Event shall
be subject to adjustment as described in paragraph (a) above following the date
of consummation of such transaction.

SECTION 1406.  Notice of Adjustments and Certain Other Events.

          (a) Whenever the Exchange Rate or the consideration receivable upon
exchange is adjusted as herein provided, the Company shall:

                  (1) forthwith compute the adjusted Exchange Rate in accordance
          with Section 1405 and prepare an Officers' Certificate setting forth
          the adjusted Exchange Rate or
<PAGE>   16
                                       15


          exchange consideration, the method of calculation thereof in
          reasonable detail, and the facts requiring such adjustment and upon
          which such adjustment is based, which certificate shall be conclusive,
          final and binding evidence of the correctness of the adjustment, and
          file such certificate forthwith with the Trustee; and

                  (2) within 10 Business Days following the occurrence of an
          event that permits or requires an adjustment to the Exchange Rate or
          exchange consideration pursuant to Section 1405 (or if the Company is
          not aware of such occurrence, as soon as practicable after becoming so
          aware), provide an Officers' Certificate to the Trustee and written
          notice to the Holders of the Outstanding Notes of the occurrence of
          such event and a statement in reasonable detail setting forth the
          method by which the adjustment to the Exchange Rate or exchange
          consideration was determined and setting forth the revised Exchange
          Rate or exchange consideration per Note.

The Trustee shall not be deemed to know of any adjustment in the Exchange Rate
or the consideration receivable upon exchange, or of any facts requiring such an
adjustment, unless and until it shall have received, at its Corporate Trust
Office, an Officers' Certificate to such effect.

          (b) In case at any time while any of the Notes are outstanding the
Company receives notice that:

                  (1) Salomon has declared a dividend (or any other
          distribution) on or in respect of the Salomon Common Stock to which
          Section 1405(a)(1) or (2) shall apply (other than any cash dividends
          and distributions, if any, paid from time to time by Salomon that do
          not constitute Extraordinary Cash Dividends);

                  (2) Salomon has authorized the issuance to all holders of
          Salomon Common Stock of rights or warrants to subscribe for or
          purchase shares of Salomon Common Stock or of any other subscription
          rights or warrants;

                  (3) there shall be proposed any conversion or reclassification
          of Salomon Common Stock (other than a subdivision or combination of
          outstanding shares of such Salomon Common Stock) or any consolidation,
          merger or reorganization to which Salomon is a party and for which
          approval of any stockholders of Salomon is required; or

                  (4) there shall be proposed the voluntary or involuntary
          dissolution, liquidation or winding up of Salomon;

then the Company shall promptly cause to be delivered to the Trustee and filed
at the office or agency maintained for the purpose of exchange of Notes in the
Borough of Manhattan, in The City of New York by the Trustee, and shall promptly
cause to be mailed to the Holders
<PAGE>   17
                                       16


of the Notes at their last addresses as they shall appear upon the registration
books of the Securities Registrar, at least 10 days before the date hereinafter
specified (or the earlier of the dates hereinafter specified, in the event that
more than one is specified), a notice stating (i) the date on which a record is
to be taken for the purpose of such dividend, distribution or grant of rights or
warrants, or, if a record is not to be taken, the date as of which the holders
of Salomon Common Stock to be entitled to such dividend, distribution or grant
of rights or warrants are to be determined, or (ii) the date, if known by the
Company, on which such reclassification, consolidation, merger, dissolution,
liquidation or winding up is expected to become effective. The Trustee shall not
be deemed to know of any declaration, issuance or proposal unless and until it
shall have received, at its Corporate Trust Office, an Officers' Certificate to
such effect.

SECTION 1407.  Taxes.

          (a) The Company will pay any and all documentary, stamp, transfer or
similar taxes that may be payable in respect of the transfer and delivery of
Salomon Common Stock pursuant hereto; provided, however, that the Company shall
not be required to pay any such tax which may be payable in respect of any
transfer involved in the delivery of Salomon Common Stock in a name other than
that in which the Notes so exchanged were registered, and no such transfer or
delivery shall be made unless and until the Person requesting such transfer has
paid to the Company the amount of any such tax, or has established, to the
satisfaction of the Company, that such tax has been paid.

          (b) The Company and, by its purchase of a Note hereby, each Holder of
a Note agree to treat, for U.S. federal income tax purposes, each Note as a
contingent payment debt instrument subject to the U.S. Treasury regulations
under the Internal Revenue Code of 1986, as amended, governing such instruments
(Treas. Reg. Section 1.1275-4) and to report all income (or loss) with respect
to the Notes in accordance with those regulations.

SECTION 1408.  Shares Free and Clear.

          The Company hereby warrants that upon exchange of any Note for Salomon
Common Stock pursuant to this Indenture, the Holder of such Note shall receive
all rights held by the Company in the Salomon Common Stock for which such Note
is at such time exchangeable pursuant to this Indenture, free and clear of any
and all liens, claims, charges and encumbrances other than any liens, claims,
charges and encumbrances which may have been placed on any Salomon Common Stock
by the prior owner thereof, prior to the time such Salomon Common Stock was
acquired by the Company. Except as provided in Section 1407, the Company will
pay all taxes and charges with respect to the delivery of Salomon Common Stock
delivered in exchange for Notes hereunder. In addition, the Company further
warrants that any Salomon Common Stock so delivered in exchange for Notes
<PAGE>   18
                                       17


hereunder shall be free of any transfer restrictions (other than such as are
solely attributable to any Holder's status as an affiliate of Salomon).

SECTION 1409.  Cancellation of Debt Security.

          Upon receipt by the Trustee of Notes delivered to it for exchange
under this Article Fourteen, the Trustee shall cancel and dispose of the same as
provided in Section 309."

          (e) By amending the table of contents of the Basic Indenture to
reflect the additions described in subsections (a) and (d) of this Section 3.

          SECTION 4. The form of Notes attached hereto as Exhibit A is hereby
adopted, pursuant to Section 202 of the Indenture, as a form of Debt Securities
of a series that consists of Notes.

          SECTION 5. The Basic Indenture, as supplemented and amended by this
Supplemental Indenture and all other indentures thereto, is in all respects
ratified and confirmed, and the Basic Indenture, this Supplemental Indenture and
all indentures supplemental thereto shall be read, taken and construed as one
and the same instrument.

          SECTION 6. If any provision hereof limits, qualifies or conflicts with
another provision hereof which is required to be included in this Supplemental
Indenture by any of the provisions of the Trust Indenture Act, such required
provision shall control.

          SECTION 7. All covenants and agreements in this Supplemental Indenture
by the Company shall bind its successors and assigns, whether so expressed or
not.

          SECTION 8. In case any provision in this Supplemental Indenture or in
the Debt Securities of any series shall be invalid, illegal or unenforceable,
the validity, legality and enforceability of the remaining provisions (or of the
other series of Debt Securities) shall not in any way be affected or impaired
thereby. If the Company elects to deliver cash in lieu of Salomon Common Stock
at Maturity, the Company will be obligated to deliver cash with respect to all,
but not less than all, of the shares of Salomon Common Stock that would
otherwise be deliverable; provided, however, that the Company will deliver
Salomon Common Stock to any Holder if in the Company's determination the
delivery of cash to such Holder may violate applicable law.

          SECTION 9. Nothing in this Supplemental Indenture, expressed or
implied, shall give to any Person, other than the parties hereto and their
successors hereunder, and the Holders of each series of Debt Securities any
benefit or any legal or equitable right, remedy or claim under this Supplemental
Indenture.

series shall be deemed to be a contract made under the laws of the State of New
York and this Supplemental Indenture and each such Debt Security shall be
governed by and construed in accordance with the laws of the State of New York.

          SECTION 11. All capitalized terms used in this Supplemental Indenture
and not otherwise defined herein that are defined in the Basic Indenture shall
have the meanings set forth therein.

          SECTION 12. This Supplemental Indenture may be executed in any number
of counterparts, each of which shall be an original; but such counterparts shall
together constitute but one and the same instrument.

          SECTION 13. The recitals contained herein and in the Debt Securities,
except the certificate of authentication of the Trustee thereon, shall be taken
as statements of the Company, and the Trustee assumes no responsibility for
their correctness. The Trustee makes no representations as to the validity or
sufficiency of the Basic Indenture, this Supplemental Indenture or of the Debt
Securities and shall not be accountable for the use or application by the
Company of the Debt Securities or the proceeds thereof.

          Berkshire Hathaway Inc., a corporation duly organized and existing
under the laws of the State of Delaware (herein called the "Company", which term
includes any successor Person under the Indenture hereinafter referred to), for
value received, hereby promises to pay to Cede & Co., or registered assigns, the
principal sum of [________________] Dollars ($[___________]) on [__________],
2001, and to pay interest thereon from [__________], 1996 or from the most
recent Interest Payment Date to which interest has been paid or duly provided
for, semi-annually on [__________] and [__________] in each year, commencing
[__________], 1997 at the rate of [___]% per annum, until the principal hereof
is paid or made available for payment. The interest so payable, and punctually
paid or duly provided for, on any Interest Payment Date will, as provided in
such Indenture, be paid to the Person in whose name this Security (or one or
more Predecessor Securities) is registered at the close of business on the
Regular Record Date for such interest, which shall be the [__________] and
[__________] (whether or not a Business Day), as the case may be, next preceding
such Interest Payment Date. Any such interest not so punctually paid or duly
provided for will forthwith cease to be payable to the Holder on such Regular
Record Date and may either be paid to the Person in whose name this Security (or
one or more Predecessor Securities) is registered at the close of business on a
Special Record Date for the payment of such Defaulted Interest to be fixed by
the Trustee, notice whereof shall be given to Holders of Securities of this
series not less than 10 days prior to such Special Record Date, or be paid at
any time in any other lawful manner not inconsistent with the requirements of
any securities exchange on which the Securities of this series may be listed,
and upon such notice as may be required by such exchange, all as more fully
provided in said Indenture.

          At Maturity, if both (1) the 10-Day Average Closing Price of Salomon
Common Stock and (2) the Closing Price of Salomon Common Stock on the last
Trading Day prior to Maturity are equal to or greater than the Exchange Price
then in effect, each Note will be exchanged by the Company into shares of
Salomon Common Stock at the Exchange Rate, or the Company may, at its option,
deliver cash, in lieu of delivering shares of Salomon Common Stock, in an amount
equal to the product obtained by multiplying the Exchange Rate by the Current
Market Price of Salomon Common Stock at Maturity. In all other circumstances,
the Company will pay at Maturity, in cash, a price per Note equal to the
principal amount due at Maturity (or, in the event the Notes mature prior to the
Maturity Date, the Accreted Value thereof). In all events, accrued and unpaid
interest to Maturity shall be payable by the Company in cash on all Notes
outstanding at Maturity. The Exchange Rate or exchange consideration will be
subject to adjustment as provided in the Indenture.

          Payment of the principal of (and premium, if any) and interest on this

Security, this Security is presented to the Trustee in time for the Trustee to
make such payments in accordance with its normal procedures.

set forth on the reverse hereof, which further provisions shall for all purposes
have the same effect as if set forth at this place.

                               REVERSE OF SECURITY

          This Security is one of a duly authorized issue of securities of the
Company (herein called the "Securities"), issued and to be issued in one or more
series under an Indenture, dated as of December 1, 1987, between the Company and
State Street Bank and Trust Company, as successor Trustee thereunder (herein
called the "Trustee", which term includes any successor trustee under the
Indenture), as supplemented by a First Supplemental Indenture, dated as of
November [___], 1996, between the Company and the Trustee (herein collectively
called the "Indenture"), and reference is hereby made to the Indenture for a
statement of the respective rights, limitations of rights, duties and immunities
thereunder of the Company, the Trustee and the Holders of the Securities and of
the terms upon which the Securities are, and are to be, authenticated and
delivered. This Security is one of the series designated on the face hereof,
limited in aggregate principal amount to [______________] dollars
($[__________]).

          Subject to and upon compliance with the provisions of the Indenture,
on the last Trading Day of each January, April, July and October, from and
including January 1997 through and including July 2001, any Notes (other than
Notes with respect to which a notice of exchange for Salomon Common Stock has
been delivered by the Company prior to such Exchange Date) will be exchangeable,
at the option of the Holder, for shares of Salomon Common Stock at the Exchange
Rate of [____] shares of Salomon Common Stock per Note (or at the current
adjusted Exchange Rate if an adjustment has been made as provided in the
Indenture), provided that the Closing Price of Salomon Common Stock on the
Exchange Date exceeds the Exchange Price then in effect, and subject to certain
additional conditions described below. In the event that a prospectus supplement
and prospectus of Salomon covering the shares of Salomon Common Stock which may
be received by a Holder of Notes upon an exchange is required to be delivered
under the Securities Act of 1933 and is not made available by Salomon to the
Company for use during any Exchange Period, the Company shall, on or prior to
the applicable Exchange Date, upon written notice to each Holder that has
complied with the procedures for exchange of Notes described herein (an
"Electing Holder"), postpone such Exchange Date from time to time until such
later Business Day (the "New Exchange Date") as the Company is able to deliver a
Salomon Prospectus or is no longer required to do so. In the event that the
Company postpones any Exchange Date, (1) no additional Notes may be delivered to
the Trustee by any Holder for exchange into Salomon Common Stock at any time
during the period from the original Exchange Date through and including the New
Exchange Date, (2) each Electing Holder shall have the right, until the New
Exchange Date, to irrevocably withdraw any Notes delivered to the Trustee on or
prior to the original Exchange Date, and (3) any Notes that have not been
withdrawn by an Electing Holder prior to the New Exchange Date shall be
exchanged for shares of Salomon Common Stock on the New Exchange Date, provided
that the Closing Price of Salomon Common Stock on the New Exchange Date exceeds
the Exchange Price then in effect. In addition, if a Reorganization Event shall
have occurred, the Notes shall not be exchangeable at the option of the Holder
for any Exchange Securities during any Exchange Period if a prospectus covering
such Exchange Securities is required to be delivered by the Company under the
Securities Act and is not available to the Company for use during such Exchange
Period.


                                       A-4
<PAGE>   26
          The Notes will not be redeemable or exchangeable at the option of the
Company prior to [_________], 1999. Thereafter, (1) at any time when both (A)
the 10-Day Average Closing Price of the Salomon Common Stock on the date on
which the applicable notice of redemption is given and (B) the Closing Price of
Salomon Common Stock on the last Trading Day prior to such date are equal to or
greater than the Exchange Price then in effect, the Company may, at its option,
either (i) exchange the Notes, in whole or in part, for shares of Salomon Common
Stock at the Exchange Rate then in effect or (ii) redeem the Notes, in whole or
in part, in cash at a price per Note equal to the product of the Exchange Rate
then in effect and the Current Market Value of Salomon Common Stock on the date
on which the applicable notice of redemption is given, and (2) at any other
time, the Company may, at its option redeem the Notes, in whole or in part, in
cash at a price per Note equal to the Accreted Value of the Notes on the date of
redemption. However, the Company may not give any notice of redemption for cash
(x) during the period from the beginning of any Exchange Period until the close
of business on the applicable Exchange Date or New Exchange Date or (y) prior to
the beginning of any Exchange Period if the Redemption Date would occur during
or after such Exchange Period. Upon any exchange or redemption described in
clause (1) above, the Holders of Notes will not receive any payment representing
accrued OID; such accrued OID will be deemed paid upon the receipt of Salomon
Common Stock or the cash equivalent received on such exchange or redemption.

          In connection with any redemption or exchange prior to Maturity of the
Notes, the Company will notify the Depositary and the Trustee and will publish a
notice in a daily newspaper of national circulation stating (1) the Exchange
Rate then in effect, (2) whether the Notes will be exchanged for shares of
Salomon Common Stock or redeemed for cash and (3) the redemption or Exchange
Date (which shall be at least 15 days but not more than 30 days after the date
of such notice). On the Exchange Date with respect to any exchange of Notes for
Salomon Common Stock, such Notes shall cease to be outstanding and shall be
deemed to represent solely the right to receive shares of Salomon Common Stock
in accordance with the terms of the Indenture. The Company will pay in cash the
accrued and unpaid interest on all Notes redeemed or exchanged to but excluding
the date of redemption or exchange.

          In any exchange of Notes for shares of Salomon Common Stock at or
prior to Maturity of the Notes, no fractional shares of Salomon Common Stock
will be issued, as provided in the Indenture. If the Company exchanges Notes for
shares of Salomon Common Stock, Holders of the Notes will be responsible for the
payment of any brokerage costs incurred upon the subsequent sale of such shares.

          If less than all the Notes then outstanding are to be redeemed or
exchanged prior to maturity of the Notes, the Trustee will select those to be
redeemed or exchanged as a whole or in part pro rata or by lot or by such method
as the Trustee shall deem fair and appropriate. Notice of redemption or exchange
will be given to holders of the Notes to be redeemed or exchanged by first-class
mail, postage prepaid at their last address appearing on the Note registry
books.

          If an Event of Default with respect to Securities of this series shall
occur and be continuing, the Accreted Value of the Securities of this series may
be declared due and payable in the manner and with the effect provided in the
Indenture.

          The Indenture permits, with certain exceptions as therein provided,
the amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders of the Securities of each series to be
affected under the Indenture at any time by the Company and the Trustee with the
consent of the Holders of 66 2/3% in principal amount of the Securities at the
time Outstanding of each series to be affected. The Indenture also contains
provisions permitting the Holders of specified percentages in principal amount
of the Securities of each series at the time Outstanding, on behalf of the
Holders of all Securities of such series, to waive compliance by the Company
with certain provisions of the Indenture and certain past defaults under the
Indenture and their consequences. Any such consent or waiver by the Holder of
this Security shall be conclusive and binding upon such Holder and upon all
future Holders of this Security and of any Security issued upon the registration
of transfer hereof or in exchange herefor or in lieu hereof, whether or not
notation of such consent or waiver is made upon this Security.

          As provided in and subject to the provisions of the Indenture, the
Holder of this Security shall not have the right to institute any proceeding
with respect to the Indenture or for the appointment of a receiver or trustee or
for any other remedy thereunder, unless such Holder shall have previously given
the Trustee written notice of a continuing Event of Default with respect to the
Securities of this series, the Holders of not less than 25% in principal amount
of the Securities of this series at the time Outstanding shall have made written
request to the Trustee to institute proceedings in respect of such Event of
Default as Trustee and offered the Trustee reasonable indemnity, and the Trustee
shall not have received from the Holders of a majority in principal amount of
Securities of this series at the time Outstanding a direction inconsistent with
such request, and shall have failed to institute any such proceeding, for 60
days after receipt of such notice, request and offer of indemnity. The foregoing
shall not apply to any suit instituted by the Holder of this Security for the
enforcement of any payment of principal hereof or any premium or interest hereon
on or after the respective due dates expressed herein.

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

          As provided in the Indenture and subject to certain limitations
therein set forth, the transfer of this Security is registrable in the Security
Register, upon surrender of this Security for registration of transfer at the
office or agency of the Company in any place where the principal of and any
premium and interest on this Security are payable, duly endorsed by, or
accompanied by a written instrument of transfer in form satisfactory to the
Company and the Security Registrar duly executed by, the Holder hereof or his
attorney duly authorized in writing, and thereupon one or more new Securities of
this series and of like tenor, of authorized denominations and for the same
aggregate principal amount, will be issued to the designated transferee or
transferees.


                                       A-6
<PAGE>   28
          The Securities of this series are issuable only in registered form
without coupons in denominations of $1,000 and any integral multiple thereof. As
provided in the Indenture and subject to certain limitations therein set forth,
Securities of this series are exchangeable for a like aggregate principal amount
of Securities of this series and of like tenor of a different authorized
denomination, as requested by the Holder surrendering the same.

          No service charge shall be made for any such registration of transfer
or exchange, but the Company may require payment of a sum sufficient to cover
any tax or other governmental charge payable in connection therewith.

          Prior to due presentment of this Security for registration of
transfer, the Company, the Trustee and any agent of the Company or the Trustee
may treat the Person in whose name this Security is registered as the owner
hereof for all purposes, whether or not this Security be overdue, and neither
the Company, the Trustee nor any such agent shall be affected by notice to the
contrary.

          All terms used in this Security which are defined in the Indenture
shall have the meanings assigned to them in the Indenture.

Gentlemen:

   
        You have requested our opinion regarding the United States federal
income tax characterization of the Notes being offered in connection with the
Registration Statement on Form S-3, Registration No. 33-30570, as filed with the
Securities and Exchange Commission on August 30, 1989 by Berkshire Hathaway
Inc., as amended by Post-Effective Amendment No. 1 to the Form S-3, filed on
November 8, 1996, and Post-Effective Amendment No. 2 to the Form S-3, filed on
November 22, 1996 (as amended, the "Registration Statement"). Terms used herein
and not otherwise defined herein shall have the same meaning as in the
Registration Statement.
    

        In rendering our opinion, we have reviewed the Registration Statement
and such other materials as we have deemed necessary or appropriate as a basis

administrative interpretations and such other authorities are subject to change
at any time and, in some circumstances, with retroactive effect. A material
change in any of the materials or authorities upon which our opinion is based
could affect our conclusions stated herein. There can be no assurance that a
contrary position will not asserted by the IRS.

        Based upon the foregoing, it is our opinion that the Notes will be
treated as single debt instruments subject to recently issued U.S. Treasury
regulations governing contingent payment debt instruments. 
    

        This opinion is being furnished in connection with the Registration
Statement. Any variation or difference in the facts from those set forth in the
Registration Statement may affect the conclusions stated herein.

        We hereby consent to the use of our name under the caption "Certain
United States Federal Income Tax Considerations" in the Registration Statement
and to the filing of this opinion as an Exhibit to the Registration Statement.
In giving this consent, we do not admit that we come within the category of
persons whose consent is required under Section 7 of the Securities Act or the
rules and regulations of the Commission thereunder.

                                        Very truly yours,
