Ladies and Gentlemen:

                  Berkshire Hathaway Inc., a Delaware corporation ("Berkshire"),
proposes to sell to the underwriters named in Schedule I hereto (the
"Underwriters"), for whom you (the "Representatives") are acting as
representatives, $440,000,000 principal face amount of its 1.00% Senior
Exchangeable Notes Due December 2, 2001 (the "Underwritten Securities"), to be
issued under an indenture (the "Indenture") dated as of December 1, 1987 between
Berkshire and State Street Bank and Trust Company, as successor trustee to the
First National Bank of Boston (the "Trustee"), as amended to the date hereof by
the First Supplemental Indenture 

- ---------------
*        Plus an option to purchase from Berkshire Hathaway Inc. up to
         $60,000,000 principal face amount of additional 1.00% Senior
         Exchangeable Notes Due December 2, 2001 to cover over-allotments.
<PAGE>   2
thereto dated as of December 2, 1996. In addition, the Underwriters will have
an option to purchase up to $60,000,000 principal face amount of such
securities (the "Option Securities" and, together with the Underwritten
Securities, the "Securities"). The Securities may be exchanged by Berkshire
under certain circumstances at maturity (including as a result of acceleration
or otherwise) or prior to maturity into shares of Common Stock, par value $1.00
per share (the "Salomon Common Stock"), of Salomon Inc, a Delaware corporation
("Salomon") (or, at Berkshire's option under the circumstances described in the
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
statement with respect to 7,766,000 shares (the "Underwritten Shares") of
Salomon Common Stock, in respect of the Underwritten Securities, plus an
additional 1,059,000 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
(c) of Section 1 and paragraph (c) of Section 2.

                  1. Representations and Warranties of Berkshire. Berkshire

the Securities Act of 1933, as amended (the "Act"), and has filed with the
Securities and Exchange Commission (the "Commission") a registration statement
(file number 33-30570) on Form S-3, including a basic prospectus, for the
registration under the Act of the offering and sale of the Securities. Berkshire
may have filed one or more amendments thereto, and may have used a Preliminary
Final Berkshire Prospectus, each of which has previously been furnished to you.

Basic Berkshire Prospectus may not include all the information with respect to
the Securities and the offering thereof required by the Act and the rules
thereunder to be included in the Final Berkshire Prospectus, the Basic Berkshire
Prospectus includes all such information required by the Act and the rules
thereunder. Berkshire will next file with the Commission pursuant to Rules 415

such registration statement relating to the Securities and the offering thereof.
As filed, such final prospectus supplement shall include all required

of any filing pursuant to Rule 424(b) and on the Closing Date, the Final

Statement which shall constitute the Statement of Eligibility and Qualification
(Form T-1) under the Trust Indenture Act of the Trustee, (ii) the information

                  (e) Berkshire has no reason to believe that the
representations and warranties of Salomon contained in Section 2 hereof are not

Registration Statement at the Salomon Effective Date. "Salomon Registration
Statement" shall mean the registration statement referred to in paragraph (a) of
this Section 2 including incorporated documents, exhibits and financial

Execution Time, in the form in which it shall become effective) and, in the
event any post-effective amendment thereto becomes effective prior to the
Closing Date, shall also mean such registration statement as so amended. Such
term shall include any Rule 430A Information deemed to be included therein at
the Salomon Effective Date as provided by Rule 430A. "Rule 430A" refers to such

                  (d) Except as disclosed in the Salomon Prospectus, there is no
pending or, to the best knowledge of Salomon, threatened action, suit or
proceeding before any court or governmental agency, authority or body or any
arbitrator to which Salomon or any of its subsidiaries is a party or of which
any property of Salomon or any of its subsidiaries is the subject that would
reasonably be expected, individually or in the aggregate, to have a material
adverse effect on the business or financial position of Salomon and its
subsidiaries taken as a whole.

                  (e) Salomon and its subsidiaries are (i) in compliance with
any and all applicable federal, state and local and foreign laws and regulations
applicable to any of them, (ii) have accomplished all registrations and received
all permits, licenses or other approvals required of them under applicable laws
and regulations to conduct their respective businesses and (iii) are in
compliance with all terms and conditions of any such registration, permit,

<PAGE>   7
approvals would not, singly or in the aggregate, have a material adverse effect
on the business or financial position of Salomon and its subsidiaries taken as a
whole.

                  (f) Pursuant to the Purchase Agreement, at any time when
Berkshire is an affiliate of Salomon within the meaning of the Act and
registration of the Shares deliverable upon exchange of the Securities at the
option of the holders of Securities is required under the Act, Salomon shall use
its reasonable efforts to cause a registration statement to be effective under
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 a purchase price of
89.417% of the principal face amount thereof, plus amortization of original
issue discount, if any, on the Securities from December 2, 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
$60,000,000 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 December 2, 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

         known to such counsel and to which Salomon or any of its subsidiaries

<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
         Prospectus and reported on by them 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;

                  (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:

                  incorporated in the Berkshire Registration Statement and the

                  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

                  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

         included or incorporated in Berkshire's Quarterly Reports on Form 10-Q,

         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

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

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).

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; provided,
however, that 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 that is to be satisfied by Salomon is not satisfied or
because of any refusal, inability or failure on the part of Salomon to perform
any agreement herein or comply with any provision hereof other than by reason
of a default by any Underwriter, Salomon shall reimburse the Underwriters
severally upon demand for all 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.

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
obligation to purchase any, of the Securities, and if such nondefaulting
Underwriters do not purchase all the Securities, this Agreement will terminate
without liability to any nondefaulting Underwriter, Berkshire or Salomon. In the
event of a default by any Underwriter as set forth in this Section 11, the
Closing Date shall be postponed for such period, not exceeding seven days, as
the Representatives shall 


                                       25


<PAGE>   26
determine in order that the required changes in the Berkshire Registration
Statement or Salomon Registration Statement and the Final Berkshire Prospectus
or Salomon Prospectus or in any other documents or arrangements may be effected.
Nothing contained in this Agreement shall relieve any defaulting Underwriter of
its liability, if any, to Berkshire, Salomon and any nondefaulting Underwriter
for damages occasioned by its default hereunder.

                  12. Termination. This Agreement shall be subject to
termination in the absolute discretion of the Representatives, by notice given
to Berkshire and Salomon prior to delivery of and payment for the Securities, if
prior to such time (i) trading in Berkshire's or Salomon's Common Stock shall
have been suspended by the Commission, (ii) trading in the securities generally
on the NYSE shall have been suspended or limited or minimum prices shall have
been established on such Exchange, (iii) a banking moratorium shall have been
declared by either Federal or New York State authorities or (iv) there shall
have occurred any outbreak or escalation of hostilities, declaration by the
United States of a national emergency or war or other calamity or crisis, the
effect of which on financial markets of the United States is such as to make it,
in the judgment of the Representatives, impracticable or inadvisable to proceed
with the offering or delivery of the Securities as contemplated by the Final
Berkshire Prospectus (exclusive of any supplement thereto).

                  13. Representations and Indemnities to Survive. The respective
agreements, representations, warranties, indemnities and other statements of
Berkshire and Salomon or their respective officers and of the Underwriters set
forth in or made pursuant to this Agreement will remain in full force and
effect, regardless of any investigation made by or on behalf of the
Underwriters, Berkshire or Salomon or any of the officers, directors or
controlling persons referred to in Section 10 hereof, and will survive delivery
of and payment for the Securities. The provisions of Sections 9 and 10 hereof
shall survive the termination or cancellation of this Agreement.

                  14. Notices. All communications hereunder will be in writing
and effective only on receipt, and, if sent to the Representatives, will be
mailed, delivered or telegraphed and confirmed to them at Seven World Trade
Center, New York, New York 10048, attention of the Legal Department; if sent to
Berkshire, will be mailed, delivered or telegraphed and confirmed to it at 1440
Kiewit Plaza, Omaha, Nebraska 68131, attention of the Chief Executive Officer;
or if sent to Salomon, will be mailed, delivered, telegraphed and confirmed to
it at Seven World Trade Center, New York, New York 10048, attention of the
Secretary.

                  15. Successors. This Agreement will inure to the benefit of
and be binding upon the parties hereto and their respective successors and the
officers and directors and controlling persons referred to in Section 10 hereof,
and no other person will have any right or obligation hereunder.

ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

agreement, please sign and return to us the enclosed duplicate hereof, whereupon

         FIRST SUPPLEMENTAL INDENTURE dated as of December 2, 1996 (this
"Supplemental Indenture"), made and entered into by and between BERKSHIRE
HATHAWAY INC., a corporation organized and existing under the laws of the State
of Delaware having its principal office at 1440 Kiewit Plaza, Omaha, Nebraska
68131 (the "Company"), and STATE STREET BANK AND TRUST COMPANY, as successor
trustee (together with its successors, the "Trustee").

         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
initial Trustee, for the purposes of issuing its unsecured debentures, notes or
other evidences of indebtedness to be issued in one or more series (the "Debt
Securities"), in such principal amount or amounts as may from time to time be
authorized by or pursuant to the authority granted in one or more resolutions of
the Board of Directors of the Company;

         WHEREAS the Company has requested the Trustee to join with it in the
execution and delivery of this First Supplemental Indenture in order to comply
with amendments to the Trust Indenture Act and to provide for a series of Debt
Securities denominated its "1.00% Senior Exchangeable Notes Due December 2,
2001" (such Debt Securities being referred to herein as the "Notes");

         WHEREAS Section 901(6) and (8) of the Basic Indenture provides that
without the consent of the Holders of Debt Securities, the Company, when
authorized by a Board Resolution, and the Trustee may enter into one or more
indentures supplemental to the Basic Indenture, in form satisfactory to the
Trustee, (a) to establish the form or terms of Debt Securities of any series and
(b) to cure any ambiguity, to correct or supplement any provision therein which
may be defective or inconsistent with any other provision therein, or to make
any other provisions with respect to matters or questions arising under the
Basic Indenture which shall not be inconsistent with the provisions of the Basic
Indenture, provided such other provisions shall not adversely affect the
interest of the Holders of Debt Securities of any series in any material
respect;

         WHEREAS the entry into this Supplemental Indenture by the parties
hereto is in all respects authorized by the provisions of the Basic Indenture;
and

         WHEREAS all things necessary to make this Supplemental Indenture a
valid agreement of the Company in accordance with its terms have been done.

         NOW, THEREFORE, and in consideration of the premises and purchase of
the Debt Securities by the Holders thereof, it is mutually covenanted and
agreed, for the equal and proportionate benefit of all Holders, without
preference, priority or distinction of any of the Debt Securities over any of
the others by reason of difference in series or priority in time of issuance,
negotiation or maturity thereof, or otherwise except as otherwise provided in
the Basic Indenture or this Supplemental Indenture, as follows:
<PAGE>   3
                                        2


         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
to add to such definition the phrase ", as amended by the Trust Indenture Reform
Act of 1990," after the date "1939" in the first line of such definition.

         (b) Section 102 of the Indenture is amended to add in the first line of
the second paragraph, after the word "Indenture", the following: "(other than
certificates provided pursuant to Section 1004)".

         (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."

         (d) Section 608 of the Indenture is amended to read in its entirety as
follows:

                  "If the Trustee has or shall acquire a conflicting interest
         within the meaning of the Trust Indenture Act, the Trustee shall either
         eliminate such interest or resign, to the extent and in the manner
         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."
<PAGE>   4
                                        3


         (e) Section 613 of the Indenture is amended to read in its entirety as
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
         after the end of each fiscal year of the Company ending after the date
         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
         terms, provisions and conditions of this Indenture (without regard to

SECTION 1401.  Payment or Exchange at Maturity.

         (a) 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 Value 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 Section 1405.

         (b) Not later than 15 days prior to Maturity, the Company will notify
the Depositary and the Trustee and will publish a notice in a daily newspaper of
national circulation stating whether the Company (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 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 December 2, 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.

                  (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.

          SECTION 10. This Supplemental Indenture and each Debt Security of any
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 December 2,
2001, and to pay interest thereon from December 2, 1996 or from the most
recent Interest Payment Date to which interest has been paid or duly provided
for, semi-annually on June 2 and December 2 in each year, commencing
June 2, 1997 at the rate of 1.00% 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 May 15 and
November 15 (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 will be made on each Interest Payment Date or at Maturity by the
Trustee as Paying Agent by wire transfer of immediately available funds to a
separate account of the Depositary or its nominee at the Federal Reserve Bank of
New York, provided that, in the case of payments made at Maturity of this
Security, this Security is presented to the Trustee in time for the Trustee to
make such payments in accordance with its normal procedures.

          Reference is hereby made to the further provisions of this Security
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
December 2, 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 FIVE HUNDRED MILLION DOLLARS
($500,000,000).

          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 17.65 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.

<PAGE>   26
          The Notes will not be redeemable or exchangeable at the option of the
Company prior to December 2, 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.

          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.
