                        DESCRIPTION OF THE CAPITAL STOCK
 
     The following description of the material terms of the Company's Capital
Stock does not purport to be complete and is qualified in its entirety by
reference to the Company's Restated Certificate of Incorporation, as amended,
and By-laws, which are incorporated by reference in this Registration Statement.
 
                      DESCRIPTION OF WILLIAMS COMMON STOCK
 
     As of September 15, 1995, there were 240,000,000 shares of Williams Common
Stock authorized and 102,107,196 outstanding (excluding 2,839,714 shares of
Williams Common Stock then held by the Company and its subsidiaries.)
 
     Holders of Williams Common Stock are entitled to dividends as declared by
the Company's Board of Directors. Debt instruments of certain subsidiaries of
the Company limit the amount of dividend payments to the Company which may
adversely impact the funds available to the Company to pay dividends on any
preferred stock and Williams Common Stock.
 
     Subject to the rights of the holders of any outstanding shares of any
preferred stock of the Company, holders of Williams Common Stock are entitled to
cast one vote for each share held of record on all matters. Voting securities do
not have cumulative voting rights. This means holders of more than 50 percent of
the voting power of all securities outstanding voting for the election of
directors can elect 100 percent of the directors if they choose to do so; and in
such event, the holders of the remaining voting power will not be able to elect
any person or persons to the Company's Board of Directors.
 
     Shareholders have no preemptive or subscription rights upon the issuance of
additional shares of the Company's stock of any class or series. Upon
liquidation or dissolution of the Company, whether voluntary or involuntary, the
holders of Williams Common Stock are entitled to share ratably in the assets of
the Company available for distribution after provision for creditors and holders
of preferred stock. All of the issued and outstanding shares of Williams Common
Stock are duly authorized, validly issued, fully paid and will not be subject to
further calls or assessments.
 
     Each share of Williams Common Stock has 0.50 Preferred Stock Purchase
Rights ("Rights") attached unless and until the Rights are redeemed.
 
                           DESCRIPTION OF THE RIGHTS
 
     The following description of the material terms of the Rights does not
purport to be complete and is qualified in its entirety by reference to the
Amended and Restated Rights Agreement, dated as of July 12, 1988, between the
Company and First Chicago Trust Company of New York which is incorporated by
reference in this Registration Statement.
 
     Rights are evidenced by certificates for Williams Common Stock and will
automatically trade with such Williams Common Stock unless and until they become
exercisable or are redeemed. If and when the Rights become exercisable, Rights
certificates will be distributed and the Rights will become separately
tradeable.
 
     Each Right entitles the holder thereof to purchase from the Company one
two-hundredth of a share of the Company's Series A Preferred Stock for a price
of $75 subject to adjustments. The Rights become exercisable after the tenth day
following the date (the "Stock Acquisition Date") on which a public announcement
is made that any person (an "Acquiring Person") has acquired beneficial
ownership of 20 percent or more of the outstanding shares of Williams Common
Stock or 10 business days following the commencement of (or a public
announcement of an intention to make) a tender or exchange offer if, upon
consummation thereof, the person or group proposing such offer would be
beneficial owner of 30 percent or more of the outstanding shares of Williams
Common Stock. The Rights expire on the earlier of (i) February 6, 1996 or (ii)
the date on which the Rights are redeemed. The Company is entitled to redeem in
whole, but not in part, the Rights at any time until 30 days following the Stock
Acquisition Date, at a redemption price of $.05 per Right.
 
                                        5
<PAGE>   7
 
     In the event that, anytime following the Stock Acquisition Date, the
Company is acquired in a merger or other business combination transaction or 50
percent or more of its assets or earning power is sold, provision shall be made
so that each holder of a Right will thereafter have the right to receive, upon
the exercise thereof at the then current Purchase Price (as defined in the
rights agreement for the Rights) of the Right, common stock of the acquiring
entity which has a value of two times the Purchase Price of the Right. Following
the occurrence of any of the events described above in this paragraph, any
Rights that are or were beneficially owned by an Acquiring Person or affiliates
or associates of any Acquiring Person will immediately become null and void.
 
     Holders of the Rights have no right to vote or to receive dividends.
 
                       DESCRIPTION OF THE PREFERRED STOCK
 
     The Company is authorized to issue up to 30,000,000 shares of Preferred
Stock, par value $1.00 per share, in one or more series. The only preferred
stock of the Company currently outstanding consists of 2.5 million shares of its
series of $3.50 Convertible Preferred Stock (the "$3.50 Shares") and 869,552
shares of its series $2.21 Preferred Stock (the "$2.21 Shares" which together
with the $3.50 Shares comprise the "Preferred Stock"). The Preferred Stock ranks
senior to Williams Common Stock upon liquidation and as to dividends and
redemption. If dividends or amounts payable on liquidation are not paid in full
on the Preferred Stock of all series, then all series share ratably in the
amount available therefor.
 
     Holders of the shares of the Preferred Stock are entitled to receive, when
and if declared by the Company's Board of Directors, annual cash dividends
payable in quarterly installments which are cumulative. Dividends are payable to
holders of record as they appear on the stock books of the Company on such
record dates not more than 60 nor less than 10 days preceding the payment dates
as shall be fixed by the Board of Directors.
 
     Unless full cumulative dividends on the Preferred Stock and any stock
ranking on parity with the Preferred Stock as to dividends or upon liquidation
("Parity Stock") have been paid or funds have been set apart for payment thereon
through the current dividend period with respect to the Preferred Stock and any
Parity Stock, the Company may not (i) declare or pay any dividend or
distribution on any junior stock of the Company or (ii) redeem or set apart
funds for the purchase or redemption of any junior stock.
 
     In the event of any liquidation, dissolution or winding up of the Company,
the holders of shares of the Preferred Stock are entitled to receive out of
assets of the Company available for distribution to shareholders, before any
distribution of assets is made to holders of Williams Common Stock, liquidating
distributions plus dividends accrued and accumulated but unpaid to the
redemption date. If upon any liquidation, dissolution or winding up of the
Company, the amounts payable with respect to the Preferred Stock and any Parity
Stock are not paid in full, the holders of the Preferred Stock and any Parity
Stock of the Company will share ratably in any such distribution of assets in
proportion to the full respective preferential amounts to which they are
entitled. After payment of the full amount of the liquidating distribution to
which they are entitled, the holders of shares of the Preferred Stock will not
be entitled to any further participation in any distribution of assets by the
Company. Neither a consolidation or merger of the Company with another
corporation nor a sale or transfer of all or part of the Company's assets for
cash or securities shall be considered a liquidation, dissolution or winding up
of the Company.
 
     The Preferred Stock is not subject to any mandatory redemption or sinking
fund provision. The Preferred Stock is redeemable on at least 30 but not more
than 60 days' notice, at the option of the Company, in whole or in part, with
respect to the $2.21 Shares, at any time on and after September 1, 1997 at a
redemption price equal to $25 per share and with respect to the $3.50 Shares, at
any time on and after November 1, 1999, in whole or in part, at a redemption
price initially equal to $51.40 per share and declining ratably to $50.00 per
share on November 1, 2003, plus, in both cases, dividends accrued and
accumulated but unpaid to the redemption date. If less than all the outstanding
shares of the Preferred Stock are to be redeemed, the Company will select those
to be redeemed by lot or a substantially equivalent method.
 
                                        6
<PAGE>   8
 
     Except as indicated below, the holders of shares of the Preferred Stock
have no voting rights. If the equivalent of six quarterly dividends payable on
the Preferred Stock or on any other preferred stock is in arrears, the number of
directors of the Company will be increased by two and the holders of all
outstanding shares of the Preferred Stock, voting as a single class without
regard to series, will be entitled to elect the additional two directors until
all dividends in arrears have been paid or declared and set apart for payment.
 
     The $2.21 Shares are not convertible into, or exchangeable for, shares of
Williams Common Stock. Each preferred share of the $3.50 Shares is convertible
at the option of the holder thereof into 1.5625 shares of Williams Common Stock
subject to certain anti-dilution adjustments. The Preferred Stock has no
preemptive rights. All of the Preferred Stock are fully paid and nonassessable.
The Preferred Stock may not be called, retired or in any way redeemed, except
pursuant to the redemption provisions set out above.
 
                              SELLING STOCKHOLDER
 
     The Selling Stockholder owns the Shares that may be offered hereby. The
Shares constitute all of the shares of Williams Common Stock held by the Selling
Stockholder prior to this offering. The Selling Stockholder acquired the Shares
over a period from August 29, 1994 through November 30, 1994, in various
open-market transactions.
 
                              PLAN OF DISTRIBUTION
 
     The Selling Stockholder may sell the Shares through underwriters, dealers
or agents, or directly to a limited number of purchasers or to a single
purchaser. A Prospectus Supplement with respect to the Shares offered thereby
will set forth the terms of the offering of such Shares, including the name or
names of any underwriters, dealers or agents, the purchase price of such Shares
and the proceeds to the Selling Stockholder from such sale, any underwriting
discounts and other items constituting underwriters' compensation, the public
offering price and any discounts or concessions allowed or reallowed or paid to
dealers. The public offering price and any discounts or concessions allowed or
reallowed or paid to dealers may be changed from time to time.
 
     If underwriters are involved in the sale, the Shares will be acquired by
the underwriters for their own account and may be resold from time to time in
one or more transactions, including negotiated transactions, at a fixed public
offering price or at varying prices determined at the time of sale. The
underwriter or underwriters with respect to a particular underwritten offering
of Shares will be named in the Prospectus Supplement relating to such offering
and, if an underwriting syndicate is used, the managing underwriter or
underwriters will be set forth on the cover page of such Prospectus Supplement.
Unless otherwise set forth in such Prospectus Supplement, the obligations of the
underwriters to purchase the Shares will be subject to certain conditions
precedent, and the underwriters will be obligated to purchase all such Shares if
any are purchased.
 
     Shares may be sold directly by the Selling Stockholder or through agents
designated by the Selling Stockholder from time to time. Any such agent, who may
be deemed to be an underwriter as that term is defined in the Securities Act,
involved in the offer or sale of any of the Shares will be named, and any
commissions payable by the Selling Stockholder to such agent will be set forth,
in the Prospectus Supplement relating to such offer or sale. Unless otherwise
indicated in such Prospectus Supplement, any such agent will be acting on a best
efforts basis for the period of its appointment.
 
     If sold through agents, the Shares offered hereby may be sold from time to
time through such agents, by means of (i) ordinary brokers' transactions, (ii)
block transactions (which may involve crosses) in accordance with the rules of
the New York Stock Exchange (Exchange), in which such agent may attempt to sell
the Shares as agent but may position and resell all or a portion of the blocks
as principal, (iii) "fixed price offerings" off the floor of the Exchange or
"exchange distributions" and "special offerings" in accordance with the rules of
the Exchange or (iv) a combination of any such methods of sale, in each case at
market prices prevailing at the time of sale in the case of transactions on the
Exchange and at negotiated prices related to prevailing market prices in the
case of transactions off the floor of the Exchange. In connection therewith,
 
                                        7
<PAGE>   9
 
distributors' or sellers' commissions may be paid or allowed that will not
exceed those customary in the types of transactions involved. If an agent
purchases Shares as principal, such stock may be resold by any of the methods of
sale described above.
 
     From time to time an agent may conduct a "fixed price offering" of Shares
covered by this Prospectus off the floor of the Exchange. In such case, such
agent would purchase a block of the Shares from the Selling Stockholder and
would form a group of selected dealers to participate in the resale of such
Shares. Any such offering would be described in a Prospectus Supplement setting
forth the terms of the offering and the number of the Shares being offered. It
is also possible that an agent may conduct from time to time "special offerings"
or "exchange distributions" in accordance with the rules of the Exchange. Any
such offering or distribution would be described in a Prospectus Supplement at
the time thereof.
 
     If a dealer is used in the sale of the Shares, the Selling Stockholder
would sell such Shares to the dealer, as principal. The dealer may then resell
such Shares to the public at varying prices to be determined by such dealer at
the time of resale. The name of any dealer involved in a particular offering of
Shares and any discounts or concessions allowed or reallowed or paid to the
dealer will be set forth in the Prospectus Supplement relating to such offering.
 
     Subject to certain conditions, the Company and the Selling Stockholder may
agree to indemnify the several underwriters, agents or dealers and their
controlling persons against certain civil liabilities, including certain
liabilities under the Securities Act, or to have the Company and the Selling
Stockholder contribute to payments any such person may be required to make in
respect hereof. Agents, underwriters and dealers may engage in transactions with
or perform services for the Company and the Selling Stockholder in the ordinary
course of business.
 
                                 LEGAL OPINIONS
 
     The legal validity of the Shares offered hereby will be passed upon for the
Company and Selling Stockholder by J. Furman Lewis, Esq., Senior Vice President
and General Counsel of the Company, and for any underwriters, dealers or agents
by Davis Polk & Wardwell.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
     The Company, a Delaware corporation, is empowered by Section 145 of the
General Corporation Law of the State of Delaware, subject to the procedures and
limitations stated therein, to indemnify any person against expenses (including
attorneys' fees), judgments, fines and amounts paid in settlement actually and
reasonably incurred by them in connection with any threatened, pending or
completed action, suit or proceeding in which such person is made party by
reason of their being or having been a director, officer, employee or agent of
the Company. The statute provides that indemnification pursuant to its
provisions is not exclusive of other rights of indemnification to which a person
may be entitled under any by-law, agreement, vote of stockholders or
disinterested directors, or otherwise. The By-laws of the Company provide for
indemnification by the Company of its directors and officers to the fullest
extent permitted by the General Corporation Law of the State of Delaware. In
addition, the Company has entered into indemnity agreements with its directors
and certain officers providing for, among other things, the indemnification of
and the advancing of expenses to such individuals to the fullest extent
permitted by law, and to the extent insurance is maintained, for the continued
coverage of such individuals.
 
     Policies of insurance are maintained by the Company under which the
directors and officers of the Company are insured, within the limits and subject
to the limitations of the policies, against certain expenses in connection with
the defense of actions, suits or proceedings, and certain liabilities which
might be imposed as a result of such actions, suits or proceedings, to which
they are parties by reason of being or having been such directors or officers.

ITEM 17. UNDERTAKINGS.
 
     (a) Rule 415 Offering. The undersigned registrant hereby undertakes:
 
          (1) To file, during any period in which offers or sales are being
     made, a post-effective amendment to this Registration Statement;
 
             (i) To include any Prospectus required by Section 10(a)(3) of the
        Securities Act of 1933;
 
             (ii) To reflect in the Prospectus any facts or events arising after
        the effective date of the Registration Statement (or the most recent
        post-effective amendment thereof) which, individually or in the
        aggregate, represent a fundamental change in the information set forth
        in the Registration Statement. Notwithstanding the foregoing, any
        increase or decrease in volume of securities offered (if the total
        dollar value of securities offered would not exceed that which was
        registered) and any deviation from the low or high end of the estimated
        maximum offering range may be reflected in the form of prospectus filed
        with the Commission pursuant to Rule 424(b) if, in the aggregate, the
        changes in volume and price represent no more than a 20 percent change
        in the maximum aggregate offering price set forth in the "Calculation of
        Registration Fee" table in the effective registration statement; and
 
             (iii) To include any material information with respect to the plan
        of distribution not previously disclosed in the Registration Statement
        or any material change to such information in the Registration
        Statement;
 
                                      II-2
<PAGE>   12
 
             provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not
        apply if the Registration Statement is on Form S-3 or Form S-8, and the
        information required to be included in a post-effective amendment by
        those paragraphs is contained in periodic reports filed by the
        Registrant pursuant to Section 13 or 15(d) of the Securities Exchange
        Act of 1934 that are incorporated by reference in the Registration
        Statement.
 
          (2) That, for the purpose of determining any liability under the
     Securities Act of 1933, each such post-effective amendment shall be deemed
     to be a new Registration Statement relating to the securities offered
     therein, and the offering of such securities at that time shall be deemed
     to be the initial bona fide offering thereof.
 
          (3) To remove from registration by means of a post-effective amendment
     any of the securities being registered which remain unsold at the
     termination of the offering.
 
     (b) Incorporation of Subsequent Exchange Act Documents. The undersigned
Registrant undertakes hereby that, for purposes of determining liability under
the Securities Act of 1933, each filing of the Registrant's annual report
pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of
1934 (and, where applicable, each filing of an employee benefit plan's annual
report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is
incorporated by reference in the Registration Statement shall be deemed to be a
new Registration Statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.
 
     (c) Indemnification. Insofar as indemnification for liabilities arising
under the Securities Act of 1933 may be permitted to directors, officers and
controlling persons of the Registrant pursuant to the foregoing provisions, or
otherwise, the Registrant has been advised that in the opinion of the Securities
and Exchange Commission such indemnification is against public policy as
expressed in the Act and is, therefore, unenforceable. In the event that a claim
for indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Act and will
be governed by the final adjudication of such issue.

                             Sales Agency Agreement




                                                              September __, 1995



SMITH BARNEY INC.
388 Greenwich Street
New York, New York  10013


Ladies and Gentlemen:

                 The undersigned, The Williams Companies, Inc., a Delaware
corporation (the "Company"), and Williams Holdings of Delaware, Inc., a
Delaware corporation, (the "Selling Stockholder"), hereby confirm their
agreement with Smith Barney Inc. (the "Agent") as follows:

                 1.       Sale of Common Stock.  The Selling Stockholder has
authorized by appropriate corporate action and proposes to sell in the manner
contemplated by this Agreement 1,197,618 shares (the "Shares") of the Company's
Common Stock (the "Common Stock"), having the terms and provisions set forth in
the Restated Certificate of Incorporation, as amended, of the Company (a copy
of which has heretofore been delivered to the Agent) and summarized in the
Prospectus hereinafter mentioned.  Subject to the terms and conditions stated
in this Agreement, the Company and the Selling Stockholder hereby (a) appoint
the Agent as the exclusive sales agent for the purpose of soliciting purchases
of the Shares from the Selling Stockholder by others and (b) agree that
whenever the Selling Stockholder determines to sell Shares directly to the
Agent as principal for resale to others, the Company and the Selling
<PAGE>   2
Stockholder will enter into a Terms Agreement (as defined in Section 2(b)
hereof) with the Agent relating to such sale in accordance with Section 2(b)
hereof.

                 2.       Solicitations as Agent; Purchases as Principal.  (a)
Solicitations as Agent.  On the basis of the representations and warranties
herein contained, but subject to the terms and conditions herein set forth, the
Agent agrees, as an agent of the Selling Stockholder, to use its reasonable
best efforts to solicit offers to purchase the Shares.  The Agent and the
Selling Stockholder agree that such solicitations, and offers for the sale of
the Shares, shall commence upon receipt of, and shall be made in accordance
with, written instructions from the Selling Stockholder to the Agent (which
shall be substantially in the form of Exhibit A hereto and which may take the
form of an exchange of any standard form of written telecommunication between
the Agent and the Selling Stockholder and shall continue until such time as the
Selling Stockholder has instructed the Agent that such solicitations and offers
shall be suspended in accordance with Section 8 hereof.  The Selling
Stockholder reserves the right, in its sole discretion, to instruct the Agent,
at any time and from time to time after the Commencement Date (as defined in
Section 7 hereof), to so commence or suspend such solicitations and offers for
any period of time or permanently in accordance with the provisions of this
Agreement.

                 In soliciting purchases of the Shares from the Selling
Stockholder by others (including customers of the Agent), the Agent will be
acting as agent for the Selling Stockholder and not as principal.  The Agent,
as the exclusive agent for the offer and sale of the Shares, will use its
reasonable best efforts to sell the Shares on behalf of the Selling Stockholder
as contemplated hereby; provided, however, that it is understood by the Selling
Stockholder that the Agent has no obligation to find purchasers of the Shares
and that the Agent in its sole discretion, upon notice thereof to the Selling
Stockholder, can suspend from time to time its efforts in offering for sale,
and soliciting purchases of, the Shares.  In any transaction where the Agent
has acted as agent for the Selling Stockholder and has not purchased as
principal, the Agent will use its reasonable best efforts to obtain performance
by each purchaser of Shares from the Selling Stockholder, but the Agent will
not have any liability to the Company and the Selling Stockholder in the event
any such purchase is not consummated for any reason except as may be otherwise
provided by any applicable regulations and rules of the Exchanges (as defined
in Section 3(a)(i) hereof) on which the transaction was




                                      2
<PAGE>   3
executed and except that the Agent will complete the purchase in accordance
with the customs of the Exchanges in the case of transactions in which the
Agent has also acted as broker for the purchaser.  The Company and the Selling
Stockholder also understand that under no circumstances shall the Agent be
obligated to purchase any Shares for its own account, except (i) pursuant to a
Terms Agreement, (ii) as provided in the preceding sentence and (iii) except to
the extent that the Agent has acted as a principal in purchasing a portion of a
block as contemplated by Section 3(a)(ii) hereof, or has made a firm commitment
with the Selling Stockholder in connection with an offering or distribution of
the type contemplated by Section 3(a)(iii) hereof that has been expressly
authorized by the Selling Stockholder and agreed to by the Agent.

                 (b)      Purchases as Principal.  Each sale of Shares to the
Agent as principal for resale to others shall be made in accordance with the
terms of this Agreement and, except for purchases made in accordance with the
customs of the Exchanges in the case of transactions in which the Agent has
also acted as broker for a purchaser and in the case of transactions permitted
by Section 3(a)(ii) hereof, a separate agreement that will provide for the sale
of such Shares to, and the purchase and reoffering thereof by, the Agent.  Each
such separate agreement (which shall be substantially in the form of Exhibit B
hereto and which may take the form of an exchange of any standard form of
written telecommunication between the Agent and the Selling Stockholder) is
herein referred to as a "Terms Agreement".  The Agent's commitment to purchase
Shares pursuant to any Terms Agreement shall be deemed to have been made on the
basis of the representations and warranties of the Company and the Selling
Stockholder herein contained and shall be subject to the terms and conditions
herein set forth.  Such Terms Agreement shall also specify the requirements for
the opinions of counsel, comfort letter and officer's certificate pursuant to
Sections 7(b), 7(c), 7(d) and 7(e), respectively, hereof.

                 3.       Manner of Offer and Sale.  (a)  Method of Offer and
Sale.  The Shares may be offered and sold by any of the following methods:

                          (i)     Ordinary Brokers' Transactions.  The Shares
         may be offered and sold by the Agent in ordinary regular-way
         transactions in the auction market on the





                                       3
<PAGE>   4
         floor of the New York Stock Exchange, Inc. (the "NYSE"), Pacific Stock
         Exchange, Inc. (the "PSE") or any other stock exchange on which the
         Common Stock may be listed or admitted to trading (the NYSE and the
         PSE, together with such other stock exchanges, the "Exchanges").

                          (ii) Block Transactions.  The Agent may solicit
         offers to purchase Shares, and offer Shares for sale, in transactions
         on the Exchanges in "crosses" of blocks where the Agent acts as broker
         for the buyers in addition to acting as agent for the Selling
         Stockholder.  It is understood that on occasion the Agent may also act
         as a principal and purchase for its own account a portion of the
         Shares being sold in the cross of a block.  The Agent may also offer
         and sell Shares in block transactions on the Exchanges in which other
         broker- dealers are acting as broker for all or some of the buyers of
         the Shares being sold in such transactions.  In the discretion of the
         Agent, the Agent may also sell Shares in block transactions to one or
         more broker-dealers purchasing such Shares, or a portion of such
         Shares, as principal for their own account.  Any of the transactions
         contemplated by this Section 3(a)(ii) may be executed in the
         over-the-counter market, with broker- dealers who are not members of
         the Exchanges or otherwise, provided that the Agent has obtained any
         necessary permission from officials of the Exchanges or such
         transactions are otherwise in compliance with the rules of the
         Exchanges.

                          (iii) Fixed Price Offerings.  With the prior
         authorization of the Selling Stockholder, and any necessary permission
         from officials of the Exchanges, the Agent may conduct fixed price
         offerings off the floor of the Exchanges, in which the Agent has
         committed to purchase as principal the Shares involved in such
         offerings and dealers selected by the Agent participate in the resale
         of such Shares.  With the prior authorization of the Selling
         Stockholder, the Agent may also conduct "special offerings" or
         "exchange distributions" of Shares on the NYSE in accordance with Rule
         391 and Rule 392, respectively, of the NYSE or on any one or more of
         the other Exchanges in accordance with the appropriate rules of such
         other Exchanges.  It is understood that the terms of "fixed price
         offerings," "special offerings" and "exchange distributions"
         contemplated by this Section 3(a)(iii) will in each case be subject to
         the prior approval of the Selling Stockholder.





                                       4
<PAGE>   5
                 (b)      Market Prices.  The Selling Stockholder understand
that sales of Shares will be made at market prices prevailing at the time of
sale in the case of transactions on the Exchanges and at prices negotiated by
the Agent and related to prevailing market prices in the case of
over-the-counter transactions; provided, however, that the price per share to
be paid to the Selling Stockholder for the Shares shall be in compliance with
the terms of this Agreement and the Procedures.

                 (c)      Discounts, Commissions, Concessions, Etc.  The
Selling Stockholder will (i) pay to the Agent, on each Settlement Date (as
defined in Section 4) in respect of the sale of any Shares solicited by the
Agent, in New York Clearing House (next day) funds, commissions for its
services in acting as agent for the Selling Stockholder in the sale of such
Shares in an amount per share to be negotiated as provided in the Procedures
(as defined in Section 3(e) hereof) for the types of transactions involved (it
being understood that the Selling Stockholder and the Agent may agree upon
payment for such commissions in such other manner as they may determine in
accordance with the Procedures) and (ii) pay the reasonable fees and expenses
of Davis Polk & Wardwell ("Counsel for the Agent") in connection with the offer
and sale of the Shares. Discounts, commissions, concessions, the offering price
and other terms of offerings or distributions referred to in Sections 2(b) and
3(a) hereof will be agreed upon by the Selling Stockholder and the Agent prior
to any such offering or distribution.  The Selling Stockholder understands and
agrees that, in any sale of Shares where the Agent is also acting as broker for
a buyer of Shares, the Agent may also receive a brokerage commission from the
buyer in any amount negotiated by the Agent and such buyer.

                 (d)      Authorized Actions.  The Selling Stockholder agrees
that, concurrently with the offer and sale of Shares on behalf of the Selling
Stockholder as contemplated by this Agreement, the Agent may (i) act as broker
for the sale of shares of Common Stock by customers other than the Selling
Stockholder, (ii) to the extent permitted by the rules and regulations of the
Securities and Exchange Commission (the "Commission") under the Securities
Exchange Act of 1934, as amended (the "Exchange Act") solicit the sale of
shares of Common Stock by customers other than the Selling Stockholder through
the Agent as broker for the seller, solicit the sale of shares of Common Stock
by customers other than the Selling Stockholder to the Agent as principal and
solicit offers to purchase shares of Common Stock and (iii) offer and sell as
principal for its own account Shares that the





                                       5
<PAGE>   6
Agent has purchased from the Selling Stockholder as contemplated by Sections
2(b) and 3(a)(ii) or shares of Common Stock that the Agent has otherwise
acquired in transactions permitted by this Agreement.

                 (e)      Procedures.  Procedural details relating to the offer
and sale of the Shares, and the issue and delivery of certificates representing
the Shares and payment for the Shares, are set forth in the Common Stock
Procedures attached hereto as Exhibit C (the "Procedures").  The Agent, the
Company and the Selling Stockholder each agree to perform the respective duties
and obligations to be performed by them as provided in the Procedures as
amended from time to time.  The Procedures may be amended only by a written
agreement of the Company, the Selling Stockholder and the Agent.  The Agent
agrees that the number of Shares to be offered and sold from time to time, and
the prices at which Shares are to be offered and sold, will be in compliance
with limitations established by the Company and the Selling Stockholder with
the Agent in accordance with the Procedures.

                 (f)      Compliance with Laws and Regulations.  The Agent
agrees that in carrying out the transactions contemplated by this Agreement, it
will observe and comply with (i) all applicable securities laws, regulations,
rules and ordinances of any jurisdiction in which the Shares may be offered,
sold or delivered and (ii) all applicable regulations and rules of the
Exchanges on which such transactions are executed.

                 4.       Delivery of Shares.  Delivery of the certificates for
Shares sold in transactions of the types referred to in Section 3(a) hereof
shall be made to the Agent at its offices at 390 Greenwich Street, New York,
New York 10013, not later than 10:00 A.M., New York City time, on the date that
is three Business Days (as defined below) after the "trade date" for the sale
of such Shares, against delivery to the Selling Stockholder in New York
Clearing House (next day) funds of the purchase price for such Shares;
provided, however, that the Selling Stockholder and the Agent may agree upon
delivery of and payment for Shares sold in particular transactions at such
other time and place and in such other manner as they may determine in
accordance with the Procedures.  The date of delivery to the Agent of
certificates for Shares sold against delivery to the Selling Stockholder of
funds in payment therefor is herein called the "Settlement Date."  Delivery of
certificates, and payment, for Shares sold pursuant to a Terms Agreement shall
be made in accordance with such Terms Agreement.  Except as may be otherwise
determined by the NYSE, "Business Day" as





                                       6
<PAGE>   7
used in this Agreement means any day on which the NYSE is open for business
other than any such day on which banking institutions in New York City are
authorized or obligated by law to close.

                 5.       Representations and Warranties of the Company and the
Selling Stockholder.  The Company and the Selling Stockholder jointly and
severally represent and warrant to the Agent that:

offering thereof from time to time in accordance with Rule 415 of the published
rules and regulations of the Commission (the "Regulations") under the Act, and
has filed such amendments thereto and such amended preliminary prospectuses, if
any, as may have been required to the date hereof.  Such registration statement
has been declared effective by the Commission.  References in this Agreement to
the "Registration Statement" at a particular time are to such registration
statement, as it may have been amended or supplemented at such time, including
all exhibits thereto and all documents that at such time are incorporated by

the Registration Statement at such time and, thereafter, to the prospectus
first filed with the Commission pursuant to Rule 424(b) of the Regulations
under the Act, as it may have been amended or supplemented at such time,
including all documents that at such time are incorporated by reference
therein.  References in this Agreement to "Incorporated Documents" at a
particular time are to the documents filed by the Company with the Commission
that are, or are deemed to be, incorporated by reference in the Prospectus at
such time as required by Item 12 of Form S-3 of the Regulations under the Act.
References in this Agreement to the terms "amend," "amendment" or "supplement"
with respect to the Registration Statement or the Prospectus shall be deemed to
refer to and include any Incorporated Document filed after the Registration
Statement became effective.

                 (b)      Registration Statement; Prospectus and Incorporated
Documents.  (i)  The Registration Statement, at the time it and any amendments
thereto were originally filed, and each preliminary prospectus filed as a part
thereof or of any amendment thereto, at the time the

<PAGE>   8
Registration Statement and any such amendment were originally filed and at the
time the Registration Statement was declared effective by the Commission, as
they may be amended or supplemented at each such time, complied in all material
respects with the applicable provisions of the Act and the Regulations
thereunder; the Incorporated Documents complied when originally filed in all
material respects with the applicable provisions of the Exchange Act and the
Regulations thereunder; (ii) the Registration Statement, at the date of this
Agreement and any applicable Terms Agreement and at the Commencement Date, as
it may be amended or supplemented at each such time, complies and will comply,
as the case may be, in all material respects with the Act and the Regulations
thereunder; the Prospectus, at the date of this Agreement and any applicable
Terms Agreement, at the date it is first filed pursuant to Rule 424(b) of the
Regulations under the Act and at the Commencement Date, as it may be amended or
supplemented at each such time, complies and will comply, as the case may be,
in all material respects with the Act and the Regulations thereunder; and (iii)
the Registration Statement, at the time it became effective, at the date of
this Agreement and any applicable Terms Agreement and at the Commencement Date,
as it may be amended or supplemented at each such time, did not, does not and
will not, as the case may be, contain an untrue statement of a material fact or
omit to state a material fact required to be stated therein or necessary to
make the statements therein not misleading; the Prospectus, at the date of this
Agreement and any applicable Terms Agreement, at the time it is first filed
pursuant to Rule 424(b) of the Regulations under the Act and at the
Commencement Date, as it may be amended or supplemented at each such time, does
not and will not, as the case may be, include an untrue statement of a material
fact or omit to state a material fact necessary in order to make the statements
therein, in the light of the circumstances under which they were made, not
misleading; provided, however, that these representations and warranties do not
apply to statements or omissions in the Registration Statement or the
Prospectus, in each case as amended or supplemented, or any preliminary
prospectus, based upon information furnished to the Company and the Selling
Stockholder in writing by the Agent expressly for use therein.

                 (c)      Financial Statements.  The financial statements
incorporated by reference in the Prospectus present fairly the financial

prepared in each case in accordance with generally accepted accounting
principles consistently applied

independent public accountants as required by the Act and the Regulations
thereunder.

                 (d)      Material Changes or Transactions.  Except as

adverse change in the business, affairs, business prospects, property or
financial condition of the Company whether or not arising in the ordinary
course of business, and since such dates there has not been any material
transaction entered into by the Company other than transactions contemplated by
the Registration Statement and the Prospectus and transactions in the ordinary
course of business.  The Company has no material contingent obligation that is
not disclosed in the Registration Statement and the Prospectus.

them is a party or in which it or any of them has a beneficial interest or by
which it or any of them may be bound, the effect of which is material to the
Company and its subsidiaries taken as a whole, and neither the execution or
delivery of this Agreement or any applicable Terms Agreement, the consummation
of the transactions herein or therein contemplated, the fulfillment of the
terms hereof or thereof nor compliance with the terms and provisions hereof or
thereof will conflict with, or result in a breach of, or constitute a default
under, (i) the certificate of incorporation, bylaws, or any contract, agreement
or other instrument that the Company, the Selling Stockholder or any of them
has assumed or to which it or any of them is now a party or in which it or any
of them has a beneficial interest or by which it or any of them may be bound or

Stockholder or the Subsidiaries of any court or any Federal or state regulatory

subsidiaries taken as a whole; all of the issued and outstanding capital stock
of the Selling Stockholder and each of the Subsidiaries has been duly   
authorized and validly issued and is fully paid and non-assessable.

                 6.       Covenants of the Company and the Selling Stockholder.
The Company and the Selling Stockholder jointly and severally covenant and
agree that:

                 (a)      Filing of Prospectus with Commission; No Stop Order.
The Company and the Selling Stockholder will cause the Prospectus, and any
amendments or supplements thereto, to be filed with, or transmitted for filing
to, the Commission in accordance with Rule 424(b) of the Regulations under the
Act and will notify the Agent immediately, and confirm such notice in writing,
of the issuance by the Commission of any stop order under the Act suspending
the effectiveness of the Registration Statement or of the initiation of any
proceedings for that purpose.  The Company and the Selling Stockholder will
make every reasonable effort to prevent the issuance by the Commission of any
stop order and, if any such stop order shall at any time be issued, to obtain
the lifting thereof at the earliest possible moment.

                 (b)      Amendments and Supplements.  The Company and the
Selling Stockholder will not file any amendment or supplement to the
Registration Statement, the Prospectus (including a prospectus filed pursuant
to Rule 424(b) of the Regulations under the Act that differs from the
Prospectus first filed pursuant to such Rule 424(b)) or any Incorporated
Document unless the Company and the Selling Stockholder have furnished to
Counsel for the Agents a copy for review prior to filing and the Company will
not file any such proposed amendment or supplement to which the Agent
reasonably objects.





                                       11
<PAGE>   12
                 (c)      Copies of Registration Statement and Prospectus.  The
Company and the Selling Stockholder will promptly deliver to the Agent a fully
executed copy of the Registration Statement as originally filed including
Incorporated Documents and of all amendments thereto, heretofore or hereafter
made, including any post-effective amendment thereto (in each case including
all exhibits filed therewith not previously furnished), including signed copies
of each consent and certificate included therein or filed as an exhibit
thereto, and will deliver to the Agent as many conformed copies of the
foregoing (excluding the exhibits) as the Agent may reasonably request.  The
Company and the Selling Stockholder will deliver to the Agent from time to time
during the period when the Prospectus is required to be delivered under the
Act, such number of copies of the Prospectus (including any amendments or
supplements thereto), as the Agent may reasonably request for the purposes
contemplated by the Act and the Regulations thereunder.

                 (d)      Compliance with the Act.  During the period when the
Prospectus is required to be delivered under the Act, the Company and the
Selling Stockholder will comply, and at their own expense, with all
requirements imposed upon them by the Act and by the Regulations thereunder, so
far as necessary to permit the continuance of sales of or dealing in the Shares
during such period in accordance with the provisions hereof and the Prospectus.

                 (e)      Changes of Material Fact.  If any event relating to
or affecting the Company and the Selling Stockholder or of which the Company
and the Selling Stockholder shall be advised in writing by the Agent shall
occur as a result of which it is necessary, in the opinion of counsel of the
Company ("Counsel for the Company") or Counsel for the Agent, to amend or
supplement the Prospectus (as it may be amended or supplemented at such time)
in order to make the Prospectus (as it may be amended or supplemented at such
time) not misleading in the light of the circumstances existing at the time it
is delivered to a purchaser, the Company and the Selling Stockholder will
forthwith (i) notify the Agent to suspend solicitations of offers to purchase,
and offers for the sale of, the Shares (and, if so notified by the Company and
the Selling Stockholder, the Agent shall forthwith suspend such solicitations
and offers and cease using the Prospectus as supplemented or amended) and (ii)
prepare and furnish to the Agent, without expense to the Agent except as
otherwise provided in Section 6(c) hereof, a reasonable number of copies of an
amendment or amendments or a supplement or





                                       12
<PAGE>   13
supplements to the Prospectus (as it may be amended or supplemented at such
time) (satisfactory in substance to the Agent and in form to Counsel for the
Agent) that will amend or supplement the Prospectus (as it may be amended or
supplemented at such time) so that as amended or supplemented it will not
include an untrue statement of a material fact or omit to state a material fact
necessary in order to make the statements therein, in the light of the
circumstances existing at the time the Prospectus (as so amended or
supplemented) is delivered to a purchaser, not misleading.  For the purpose of
this Section 6(e) the Company and the Selling Stockholder will furnish such
information as the Agent may from time to time reasonably request.

                 (f)      Earning Statement.  In accordance with Rule 158(b) of
the Regulations under the Act, the Company will make generally available to its
security holders, as soon as practicable, an earning statement (which need not
be audited) in reasonable detail covering the 12 months beginning on the first
day of the month next succeeding the month in which occurred the effective date
of the Registration Statement.

                 (g)      Blue Sky Qualification.  The Company will use its
best efforts to qualify the Shares for offer and sale under the blue sky laws
of such jurisdictions as the Agent may reasonably designate, and will file and
make in each year such statements or reports as are or may be reasonably
required by the laws of such jurisdictions; provided, however, that the Company
shall not be required to qualify as a foreign corporation or dealer in
securities or to file any consents to service of process under the laws of any
jurisdiction.

                 (h)      Payment of Expenses.  Whether or not the transactions
contemplated hereunder are consummated or this Agreement or any applicable
Terms Agreement is terminated, the Selling Stockholder will pay all expenses
incident to the performance of its obligations under this Agreement or such
Terms Agreement, including, (i) the preparation, printing and filing of this
Agreement, such Terms Agreement, the Registration Statement as originally filed

case in quantities as required by the Agent under this Agreement, (ii) the
issue and delivery of the Shares as provided in Section 4 hereof, (iii) the

<PAGE>   14
disbursements of the accountants, (iv) the expenses in connection with the
qualification of the Shares under securities laws in accordance with the
provisions of Section 6(g) hereof, including filing fees and the fees and
disbursements of Counsel for the Agent in connection therewith and in
connection with the preparation of any Blue Sky Survey, (v) the reasonable fees
and expenses of Counsel for the Agent and other out-of-pocket expenses of the
Agent related to the Agent's services through the Commencement Date in
connection with the development of the program for the offer and sale of the
Shares as contemplated hereby, not exceeding in the aggregate [$       ]
(exclusive of fees and expenses referred to in clause (iv) of this Section
6(h)), (vi) the commissions and amounts payable in accordance with Section 3(c)
hereof and (vii) any advertising and other out-of-pocket expenses of the Agent
incurred with the approval of the Selling Stockholder.  If this Agreement is
terminated in accordance with the provisions of Section 7 or 12 hereof, the
Company and the Selling Stockholder shall reimburse the Agent for reasonable
out-of-pocket expenses in an amount not exceeding [$       ] in the aggregate,
and for reasonable fees and disbursements of Counsel for the Agent.  The
Company and the Selling Stockholder shall not in any event be liable to the
Agent for damages on account of the loss of anticipated profits.

                 7.       Conditions of Agent's Obligations.  The obligation of
the Agent to solicit offers to purchase the Shares as agent of the Company and
the Selling Stockholder, the obligation of any purchaser of Shares sold through
the Agent as agent and the obligation of the Agent to purchase Shares pursuant
to any Terms Agreement shall be subject at 9:30 A.M., New York City time, on

times thereafter, to the accuracy in all material respects of the
representations and warranties on the part of the Company and the Selling
Stockholder herein contained and to the accuracy of the statements of the
Company's and the Selling Stockholder's officers made in any certificate

                                       16
<PAGE>   17
         Regulations under the Act (except in each case as to the financial
         statements and other financial or statistical data contained therein,
         upon which such opinion need not pass, and except for Incorporated
         Documents), complied as to form in all material respects with the
         requirements of the Act and the Regulations thereunder; each
         Incorporated Document as originally filed pursuant to the Exchange Act

         data contained therein, upon which such opinion need not pass)
         complied as to form when so filed in all material respects with the
         requirements of the Exchange Act and the Regulations thereunder; the

         counsel, no proceedings for a stop order with respect thereto are
         threatened or pending under Section 8 of the Act; and nothing has come
         to the attention of such counsel that has caused them to believe that
         the Registration Statement, at the time it became effective, contained
         an untrue statement of a material fact or omitted to state a material
         fact required to be stated therein or necessary to make the statements
         therein not misleading or that the Prospectus, at the time the
         Registration Statement became effective, at the time it was first
         filed pursuant to Rule 424(b) of the Regulations under the Act or on
         the Commencement Date, included or includes an untrue statement of a
         material fact or omitted or omits to state a material fact necessary
         in order to make the statements therein, in the light of the
         circumstances under which they were made, not misleading; and

                          (xiii)  to the best of such counsel's knowledge and
         information, there are no legal, governmental or regulatory
         proceedings pending or threatened that are required to be disclosed in
         the Registration Statement other than those disclosed therein.

In rendering the above opinions, Counsel for the Company and the Selling
Stockholder may rely, as the matters of fact, to the extent deemed proper, on
certificates of responsible officers of the Company, the Selling Stockholder
and the Company's subsidiaries and public officials.  References to the
Prospectus in this Section 7(b) include any amendments or supplements thereto
at the date such opinion is rendered.

                 (c)      Opinion of Counsel for the Agent.  On the
Commencement Date and, if specified in any Terms Agreement, the Settlement Date
therefor, the Agent shall have received





                                       17
<PAGE>   18
the favorable opinion dated as of the Commencement Date or such Settlement
Date, as the case may be, of Counsel for the Agent with respect to the matters
set forth in paragraphs (i), (ii), (vii), (ix), (x) and, except as to
Incorporated Documents, (xii) of Section 7(b) hereof,] and with respect to such
other matters as the Agent may reasonably require.

                 (d)      Comfort Letter.  On the Commencement Date and, if
specified in any Terms Agreement, the Settlement Date therefor, a letter dated
as of the Commencement Date or such Settlement Date, as the case may be, from
Ernst & Young LLP, confirming that they are independent public accountants
within the meaning of the Act and the Regulations thereunder with respect to
the Company, the Selling Stockholder and the Company's subsidiaries and stating
in effect that:

                          (i)     in their opinion, the audited consolidated
         financial statements and financial statement schedules included or
         incorporated by reference in the Registration Statement examined by
         them comply as to form in all material respects with the applicable
         accounting requirements of the Act and the Exchange Act and in each
         case the Regulations thereunder;

                          (ii)    on the basis of a reading of the unaudited
         consolidated financial statements included or incorporated by
         reference in the Registration Statement and the related unaudited
         consolidated financial statements from which such amounts were
         derived, the latest available interim unaudited consolidated financial
         statements of the Company, inquiries of officials of the Company
         responsible for financial and accounting matters and a reading of the
         minutes of meetings of the shareholders and the Board of Directors of
         the Company and committees thereof through a specified date not more
         than three Business Days prior to the date of their letter, nothing
         came to their attention that caused them to believe that:  (A) the
         unaudited consolidated financial statements included or incorporated
         by reference in the Registration Statement were not determined in
         accordance with generally accepted accounting principles applied on a
         basis substantially consistent with that of the corresponding amounts
         in the audited financial statements included or incorporated by
         reference in the Registration Statement; (B) for the twelve months
         ended as of the date of the latest available financial statements of
         the Company, there were any decreases in revenues, earnings on common
         stock or earnings per common share as compared with the comparable
         period of the preceding





                                       18
<PAGE>   19
         year; (C) at the date of the latest available interim consolidated
         balance sheet read by them and at a subsequent date not more than
         three Business Days prior to the date of such letter, there was any
         change in the capital stock [(except for sales under the Company's
         Stock Purchase Plan)] or long-term debt of the Company or any 
         decrease in its net assets as compared with the amounts shown in the 
         most recent consolidated balance sheet included or incorporated by
         reference in the Registration Statement, except in all instances for
         changes or decreases that the Registration Statement, as amended or
         supplemented, discloses have occurred or will occur, or for changes or
         decreases described in such letter that are reasonably satisfactory to
         the Agent;

                          (iii)  if unaudited pro forma financial statements
         are included or incorporated by reference in the Registration
         Statement, on the basis of a reading of the unaudited pro forma
         financial statements, carrying out certain specified procedures,
         inquiries of certain officials of the Company and the company acquired
         or to be acquired who have responsibility for the financial and
         accounting matters and proving the arithmetic accuracy of the
         application of the pro forma adjustments to the historical amounts in
         the pro forma financial statements, nothing came to their attention
         that caused them to believe that the pro forma financial statements do
         not comply in form in all material respects with the applicable
         accounting requirements of Rule 11-02 of the Regulation S-X or that
         the pro forma adjustments have not been properly applied to the
         historical amounts in the compilation of such statements; and

                          (iv)   covering such other matters as the Agent
         shall reasonably request.

                 (e)      Certificate as to No Material Adverse Change, Etc.
On the Commencement Date and on each Settlement Date in respect of a Terms
Agreement, there shall not have been, since the respective dates as of which
information is given in the Registration Statement and the Prospectus, except
as may otherwise be stated therein or contemplated thereby, any material
adverse change in the condition of the Company and its subsidiaries taken as 
a whole, financial or otherwise, or in the earnings, affairs or business 
prospects of the Company





                                       19
<PAGE>   20
and its subsidiaries taken as a whole, whether or not arising in the ordinary
course of business, and the Agent shall have received a certificate of the
Company signed by the President, the Executive Vice President or any other Vice
President of the Company reasonably satisfactory to the Agent, dated as of the
Commencement Date or, if specified in such Terms Agreement, the Settlement Date
therefor, as the case may be, to the effect that (i) there has been no such
material adverse change, (ii) the other representations and warranties
contained in this Agreement are true and correct with the same force and effect
as though expressly made on and as of the Commencement Date or such Settlement
Date, as the case may be, (iii) the Company and the Selling Stockholder have
complied with all agreements and satisfied all conditions on its part to be
performed or satisfied under this Agreement or such Terms Agreement, as the
case may be, on or prior to the Commencement Date or such Settlement Date, as
the case may be, and (iv) no stop order suspending the effectiveness of the
Registration Statement has been issued and no proceedings for that purpose have
been initiated or threatened by the Commission.

                 (f)      Other Documents.  On the Commencement Date, and on
each Settlement Date in respect of a Terms Agreement, Counsel for the Agent
shall have been furnished with such documents and opinions as they may
reasonably require for the purpose of enabling them to pass upon the sale of
the Shares as herein contemplated and related proceedings, or in order to
evidence the accuracy or completeness of any of the representations or
warranties, or the fulfillment of any of the conditions, herein contained, and
all proceedings taken by the Company and the Selling Stockholder in connection
with the sale of the Shares as herein contemplated shall be satisfactory in
form and substance to the Agent and Counsel for the Agent.

                 In case any of the conditions specified above in this Section
7 shall not have been fulfilled, this Agreement or any applicable Terms
Agreement may be terminated by the Agent upon mailing or delivering written
notice thereof to the Company and the Selling Stockholder.  Any such
termination shall be without liability of any party to the other party except
as otherwise provided in Section 6(h) hereof and except for any liability under
Section 10 hereof.

                 8.       Suspension of Offers and Solicitations.  At any time
and from time to time after the Commencement Date (except any such time that
the Agent owns any Shares purchased as principal that are held for resale to
others in accordance with the terms of this Agreement), the Selling





                                       20
<PAGE>   21
Stockholder may in its sole discretion instruct the Agent in writing (which
shall be substantially in the form of Exhibit D hereto and which may take the
form of an exchange of any standard form of written telecommunication between
the Selling Stockholder and the Agent) to suspend solicitations of offers to
purchase, and offers for the sale of, the Shares as provided herein and in the
Procedures.  If at any such time, or at any time that the Selling Stockholder
has otherwise notified the Agent to suspend such solicitation and offers under
this Agreement, there shall be any sales of Shares by the Selling Stockholder
not yet settled outstanding, the Selling Stockholder will promptly advise the
Agent whether such sales may be settled and whether the Prospectus as then in
effect may be delivered in connection with the settlement of such sales.  If
the Selling Stockholder determines that such sales may not be settled or that
such Prospectus may not be so delivered, the Agent will use its best efforts to
arrange for the cancellation of such sales, but the Company and the Selling
Stockholder shall have the sole responsibility for, and shall hold the Agent
harmless from, any losses, claims, damages or liabilities (and expenses in
connection therewith) that may result from the inability to make settlement of
such sales.

                 9.       Additional Representations and Warranties and 
Agreements of the Company and the Selling Stockholder.  The Company and the
Selling Stockholder jointly and severally represent and warrant and agree that:

                 (a)      Affirmation of Representations and Warranties.  Each
authorization by the Company and the Selling Stockholder to the Agent to
solicit offers to purchase the Shares as provided in the Procedures shall be
deemed to be an affirmation that the representations and warranties of the
Company and the Selling Stockholder contained in this Agreement are true and
correct at the time of such authorization, and an undertaking that such
representations and warranties will be true and correct at the time of delivery
of and payment for Shares sold pursuant to such authorization as provided in
Section 4 hereof, in each case as though made at and as of each such time
(except that such representations and warranties shall be deemed to relate to
the Registration Statement and the Prospectus as amended or supplemented to
each such time).

                 (b)      Subsequent Delivery of Certificates.  Each time that
the Registration Statement or the Prospectus shall be amended or supplemented,
the Company and the Selling Stockholder shall furnish or cause to be furnished
forthwith to the Agent a certificate of the Company and the Selling Stockholder
in form and substance satisfactory to the Agent





                                       21
<PAGE>   22
in its reasonable judgment to the effect that the statements contained in the
certificate referred to in Section 7(e) hereof that was last furnished to the
Agent are true and correct at the time of such amendment or supplement or
filing as though made on and as of such time (except that such statements shall
be deemed to relate to the Registration Statement and the Prospectus as amended
or supplemented to such time) or, in lieu of such certificate, a certificate,
in form and substance satisfactory to the Agent in its reasonable judgment, of
the same general tenor as the certificate referred to in said Section 7(e) but
modified to relate to the Registration Statement and the Prospectus as amended
or supplemented to the time of delivery of such certificate.

                 (c)      Subsequent Delivery of Legal Opinions.  Each time
that the Registration Statement or the Prospectus shall be amended or
supplemented, the Company and the Selling Stockholder shall furnish or cause to
be furnished forthwith to the Agent a favorable opinion of Counsel for the
Company and the Selling Stockholder, dated the date of delivery thereof and in
form and substance satisfactory to Counsel for the Agent, of the same tenor as
the opinion required by clauses (vi) and (xii) of Section 7(b) hereof but
modified to relate to the Registration Statement and the Prospectus as amended
or supplemented to the date of such opinion or, in lieu of such opinion,
Counsel for the Company and the Selling Stockholder may furnish to the Agent a
letter to the effect that the Agent may rely on the opinion last furnished to
the Agent to the same extent as though it were dated the date of such letter
authorizing reliance (except that statements in such last opinion shall be
deemed to relate to the Registration Statement and the Prospectus as amended or
supplemented to the time of delivery of such letter authorizing reliance).

                 (d)      Subsequent Delivery of Comfort Letters.  Each time
that the Registration Statement or the Prospectus shall be amended or
supplemented to set forth amended or supplemental financial information, the
Company shall cause Ernst & Young LLP to furnish to the Agent a letter, dated
the date of filing such amendment or supplement or document with the
Commission, in form and substance satisfactory to the Agent in its reasonable
judgment, of the same general tenor as the letter referred to in Section 7(d)
hereof but modified to the extent necessary to reflect changes in the financial
information included or incorporated by reference in the Registration Statement
and the Prospectus as then amended or supplemented since the date of the last
previous such letter furnished to the Agent.





                                       22
<PAGE>   23
                 Notwithstanding the foregoing, it is agreed that if, at any
time and from time to time during the term of this Agreement, the Selling
Stockholder should deliver to the Agent instructions to suspend solicitations
of offers to purchase, and offers for the sale of, Shares pursuant to Section
6(e) or 8 hereof, then during the period of any such suspension the Company and
the Selling Stockholder shall be relieved of its obligation to provide to the
Agent the certificates, the opinions of counsel and the comfort letters
required pursuant to Sections 9(b), 9(c) and 9(d), respectively, hereof.  Upon
instructions to commence such solicitations and offers pursuant to Section 2(a)
hereof, the Company and the Selling Stockholder shall deliver to the Agent,
prior to the resumption of such solicitations and offers, the certificate,
opinion of counsel and comfort letter required pursuant to Sections 9(b), 9(c)
and 9(d), respectively, hereof, except they shall be modified to relate to the
Registration Statement and the Prospectus as amended or supplemented to the
date of such commencement.

                 10.      Indemnification.  (a)  Indemnification of the Agent.
The Company and the Selling Stockholder, severally and jointly, will indemnify
and hold harmless the Agent and each person, if any, who controls the Agent
within the meaning of Section 15 of the Act as follows:

                          (i)     against any and all loss, liability, claim,
         damage and expense whatsoever, as incurred, arising out of any untrue
         statement or alleged untrue statement of a material fact contained in
         the Incorporated Documents and the Registration Statement (or any
         amendment thereto), or the omission or alleged omission therefrom of a
         material fact required to be stated therein or necessary to make the
         statements therein not misleading or arising out of any untrue
         statement or alleged untrue statement of a material fact contained in
         any related preliminary prospectus, the Prospectus (or any amendment
         or supplement thereto) or the Incorporated Documents, or the omission
         or alleged omission therefrom of a material fact necessary in order
         make the statements therein, in the light of the circumstances under
         which they were made, not misleading, unless such untrue statement or
         omission or such alleged untrue statement or omission was made in
         reliance upon and in conformity with written information furnished to
         the Company and the Selling Stockholder by the Agent expressly for use
         in the Registration Statement (or any amendment thereto) or such
         preliminary prospectus or the Prospectus (or any amendment or
         supplement thereto); provided, however, that any such indemnity with
         respect to a Prospectus





                                       23
<PAGE>   24
         shall not inure to the benefit of the Agent (or of any person
         controlling the Agent) on account of any losses, liabilities, claims
         or damages arising from the sale of Shares to any person if any
         amendments or supplements to such Prospectus shall have been furnished
         to the Agent on a timely basis to permit the Agent to send or give to
         such person, with or prior to the written confirmation of such sale, a
         copy of such amended or supplemented Prospectus, except the
         Incorporated Documents, and the untrue statement or omission of a
         material fact contained in such Prospectus and giving rise to such
         losses, liabilities, claims or damages was corrected in such amended
         or supplemented Prospectus (including the Incorporated Documents);

                          (ii)    against any and all loss, liability, claim,
         damage and expense whatsoever, as incurred, to the extent of the
         aggregate amount paid in settlement of any litigation, commenced or
         threatened or of any claim whatsoever based upon any such untrue
         statement or omission, or any such alleged untrue statement or
         omission, if such settlement is effected with the written consent of
         the Company and the Selling Stockholder; and

                          (iii)   against any and all expense whatsoever, as
         incurred, in investigating, preparing or defending against any
         litigation, commenced or threatened, or any claim whatsoever based
         upon any such untrue statement or omission, or any such alleged untrue
         statement or omission, to the extent that any such expense is not paid
         under clause (i) or (ii) above.

                 (b)      Indemnification of Company and the Selling
Stockholder.  The Agent agrees to indemnify and hold harmless the Company and
the Selling Stockholder, their directors, each of its officers who signed the
Registration Statement, and each person, if any, who controls the Company and
the Selling Stockholder within the meaning of Section 15 of the Act against any
and all loss, liability, claim, damage and expense described in the indemnity
contained in Section 10(a) hereof, as incurred, but only with respect to untrue
statements or omissions, or alleged untrue statements or omissions, made in the
Registration Statement (or any amendment thereto) or any preliminary prospectus
or the Prospectus (or any amendment or supplement thereto) in reliance upon and
in conformity with written information furnished to the Company and the Selling
Stockholder by the Agent expressly for use in the Registration Statement (or
any amendment thereto) or such preliminary prospectus or the Prospectus (or any
amendment or supplement thereto).





                                       24
<PAGE>   25
                 (c)      General.  Each indemnified party shall give prompt
notice to each indemnifying party of any action commenced against it in respect
of which indemnity may be sought hereunder, but failure so to notify an
indemnifying party shall not relieve it from any liability except to the extent
that it has been prejudiced in any material respect by such failure or from any
liability that it may have to such indemnified party otherwise than on account
of this indemnity agreement.  An indemnifying party may participate at its own
expense in the defense of such action.  If it so elects within a reasonable
time after receipt of such notice, an indemnifying party, jointly with any
other indemnifying parties receiving such notice, may assume the defense of
such action with counsel chosen by it and approved by the indemnified parties
defendant in such action, unless such indemnified parties reasonably object to
such assumption on the ground that there may be legal defenses available to
them that are different from or in addition to those available to such
indemnifying party, in which case the indemnifying party cannot assume the
control of the defense.  If an indemnifying party assumes the defense of such
action, the indemnifying parties shall not be liable for any fees or expenses
of counsel for the indemnified parties incurred thereafter in connection with
such action except under the circumstances stated above.  In no event shall the
indemnifying parties be liable for the fees and expenses of more than one
counsel for all indemnified parties in connection with any one action or
separate but similar or related actions in the same jurisdiction arising out of
the same general allegations or circumstances.

                 (d)      Contribution.  If the indemnification provided for in
this Section 10 is unavailable to or insufficient to hold harmless an
indemnified party under Section 10(a) or (b) hereof in respect of any losses,
claims, damages or liabilities (or actions in respect thereof) referred to
therein, then each indemnifying party shall contribute to the amount paid or
payable by such indemnified party as a result of such losses, claims, damages
or liabilities (or actions in respect thereof) in such proportion as is
appropriate to reflect the relative benefits received by the Company and the
Selling Stockholder on the one hand and the Agent on the hand from the offering
of the relevant Shares.  If, however, the allocation provided by the
immediately preceding sentence is not permitted by applicable law or if the
indemnified party failed to give the notice required under Section 10(c) hereof
and such indemnifying party was prejudiced in a material respect by such
failure, then each indemnifying party shall contribute to such amount paid or
payable by





                                       25
<PAGE>   26
such indemnified party in such proportion as is appropriate to reflect not only
such relative benefits but also the relative fault of the Company and the
Selling Stockholder on the one hand and the Agent on the other hand in
connection with the statements or omissions that resulted in such losses,
claims, damages or liabilities (or actions in respect thereof), as well as any
other relevant equitable considerations.  The relative benefits received by the
Company and the Selling Stockholder on the one hand and the Agent on the other
hand shall be deemed to be in the same proportion as the total net proceeds
from the relevant offering (before deducting expenses received by the Company)
bear to the total commissions received by the Agent. The relative fault shall
be determined by reference to, among other things, whether the untrue or
alleged untrue statement of a material fact or the omission or alleged omission
to state a material fact relates to information supplied by the Company and the
Selling Stockholder or the Agent and the parties' relative intent, knowledge,
access to information and opportunity to correct or prevent such statement or
omission.  The Company, the Selling Stockholder and the Agent agree that it
would not be just and equitable if contribution pursuant to this Section 10(d)
were determined by pro rata allocation or by any other method of allocation
that does not take account of the equitable considerations referred to above in
this Section 10(d).  The amount paid or payable by an indemnified party as a
result of the losses, claims, damages or liabilities (or actions in respect
thereof) referred to above in this Section 10(d) shall be deemed to include any
legal or other expenses reasonably incurred by such indemnified party in
connection with investigating or defending any such action or claim.  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.

                 11.      Survival of Representations and Warranties and
Agreements.  The indemnity and other agreements of the Company, the Selling
Stockholder and the Agent contained in Section 3(f) and 10 hereof and the
representations, warranties and other statements of the Company and the





                                       26
<PAGE>   27
Selling Stockholder set forth in this Agreement or made by the Company and the
Selling Stockholder pursuant to this Agreement shall remain in full force and
effect, regardless of (a) any termination of this Agreement or any Terms
Agreement, (b) any investigation made by or one behalf of the Agent or any of
its controlling persons or by or on behalf of the Company and the Selling
Stockholder or any of their officers, directors or controlling persons and (c)
acceptance of delivery of and payment for Shares sold hereunder.

                 12.      Termination.  (a)  Termination of this Agreement.
This Agreement may be terminated at any time by any party hereto upon the
giving of written notice of such termination to the other parties hereto
effective at the close of business on the date such notice is received.

                 (b)      Termination of a Terms Agreement.  The Agent may, by
notice to the Company and the Selling Stockholder, terminate a Terms Agreement
if, at any time after the date of this Agreement and at or prior to the
Settlement Date in respect thereof, (i) a general bank moratorium shall have
been declared by Federal authorities or authorities in the State of New York or
Delaware that in the Agent's judgment would materially restrict a free market
for the Shares, (ii) there shall have occurred any suspension of trading of any
securities of the Company on any exchange or in any over-the-counter market or
in securities generally on the NYSE or there shall have been established by the
NYSE, the PSE, the American Stock Exchange, Inc., the National Association of
Securities Dealers, Inc. or the Commission, or by any federal or state agency
or by the decision of any court, any limitations on the prices for such trading
or any restrictions on the distribution of securities, (iii) there shall have
occurred any outbreak of hostilities, or escalation thereof, or other national
or international calamity or crisis, the effect of which on the financial
markets of the United States shall be as such as to make it impracticable for
the Agent to enforce contracts for the sale of the Shares, (iv) the Company
shall have sustained a substantial loss (whether or not covered by insurance)
by fire, flood, accident or other calamity that renders it impractical to
consummate the sale of the Shares and the delivery of the Shares by the Agent
or (v) there shall have occurred a change in financial or economic conditions
generally the effect of which on the Company or the financial markets in the
Agent's reasonable judgment is so material and adverse as to make it
impracticable or inadvisable to consummate the sale and delivery of any Shares
by the Agent.





                                       27
<PAGE>   28
                 (c)      General.  In the event of any termination under
Section 12(a) or 12(b) hereof, no party will have any liability to any other
party hereto, except that (i) the Agent shall be entitled to any commission
earned in accordance with Section 3(c) hereof, (ii) if at the time of
termination (A) the Agent shall own any Shares purchased pursuant to a Terms
Agreement with the intention of reselling them or (B) an offer to purchase any
of the Shares has been accepted by the Selling Stockholder but the time of
delivery to the purchaser or his agent of the Shares relating thereto has not
occurred, the covenants set forth in Sections 6 and 9 hereof shall remain in
effect until such Shares have been resold or delivered, as the case may be and
(iii) the covenants set forth in Sections 6(f) and 6(h) hereof, the indemnity
and contribution agreement set forth in Section 10 hereof and the provisions of
Sections 11 and 16 hereof shall remain in effect.

                 13.      Notices.  Except as otherwise specifically provided
herein or in the Procedures, all statements, instructions, requests, notices
and advances hereunder and under any applicable Terms Agreement shall be in
writing (or by telephone or telegram if subsequently confirmed in writing), and

Company and the Selling Stockholder, The Williams Companies, Inc., One 
Williams Center, Tulsa, OK 74172, Attention: J. Furman Lewis, General Counsel,

Terms Agreement shall inure solely to the benefit of the Company, the Selling
Stockholder and the Agent and, to the extent provided in Sections 10 and 11
hereof, to any officer or director of the Company and the Selling Stockholder
or to any person who controls the Company and the Selling Stockholder or the
Agent, and their respective successors.  No other person, partnership,
association or corporation shall acquire or have any right under or by virtue
of this Agreement or any Terms Agreement.  The term "successors" shall not
include any purchaser of any Shares merely because of such purchase.  The
respective rights and obligations of

<PAGE>   29
the Company, the Selling Stockholder and the Agent hereunder may not be
assigned, transferred or contracted to another.

                 15.      Arm's Length Dealing.  This Agreement and any
applicable Terms Agreement have been negotiated at arm's length between the
Agent, the Company and the Selling Stockholder, which regularly issues and
sells securities in the public markets through investment bankers, and the
relationship created hereby or thereby is not intended to be one of customer
and member as the term "customer" is used in the provisions pertaining to the
protection of customers of the articles, bylaws, rules, regulations and
policies of the NYSE or the National Association of Securities Dealers, Inc.

                 16.      Governing Law.  This Agreement and any Terms
Agreement shall be governed by and construed in accordance with the laws of the
State of New York applicable to contracts made and to be performed within the
State of New York.

                 17.      Captions.  Captions to Sections of this Agreement 
are included for convenience of reference only and shall not constitute a part

                                          forthwith suspend such activities until such time as the

                                          or the Prospectus, it will promptly advise Smith Barney
                                          and will furnish Smith Barney with the proposed amendment

                                          outstanding, the Selling Stockholder will, consistent with
                                          its obligations under the Sales Agency Agreement, promptly

The Williams Companies, Inc.
One Williams Center
Tulsa, OK  74172

Gentlemen:

The Williams Companies, Inc., a Delaware corporation ("Williams"), has filed a
Registration Statement on Form S-3 under the Securities Act of 1933, as
amended, (the "Act") in connection with the proposed sale of up to 1,197,618
shares of Common Stock (par value $1.00 per share) of Williams and accompanying
Preferred Stock purchase rights ("Shares"), by Williams Holdings of Delaware,
Inc. (the "Selling Stockholder"), a wholly-owned subsidiary of Williams.


As General Counsel of Williams and as counsel for the Selling Stockholder, I
have examined the corporate proceedings and such other legal matters as I
deemed relevant to the registration and sale of the Shares. Based on such
examination, it is my opinion that when the Shares have been registered and
sold by the Selling Stockholder, the Shares will be legally issued, fully paid
and nonassessable.

I do not find it necessary for the purpose of this opinion, and, accordingly, do
not purport to cover herein, the application of the "Blue Sky" or securities
law of various states to offers or sales of the Shares.

I hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the references to the undersigned in such
Registration Statement. In giving this consent, I do not concede that I am an
expert within the meaning of the Act or the rules and regulations thereunder,
or that this consent is required by Section 7 of the Act.

                                      Very truly yours,

                                      /s/ J. FURMAN LEWIS

                       CONSENT OF INDEPENDENT AUDITORS



We consent to the reference to our firm under the caption "Experts" in the
