Item 1.          Security and Issuer.

                 This statement relates to the shares of Common Stock, no par
value (the "Agouron Common Stock"), of Agouron Pharmaceuticals, Inc., a
California corporation ("Agouron").  The principal executive offices of
Agouron are located at 10350 North Torrey Pines Road, La Jolla, California
92037.

Item 2.          Identity and Background.

                 This statement is being filed by Warner-Lambert Company
("Warner-Lambert").  The principal offices of Warner-Lambert are located at
201 Tabor Road, Morris Plains, New Jersey 07950-2693.  Warner-Lambert is
principally engaged in the business of developing, manufacturing and
marketing health care and consumer products.

                 The name, address, present principal occupation or
employment, and citizenship of each director and executive officer of Warner-
Lambert are set forth on Schedule 1 hereto and are incorporated herein by
reference.

                 During the past five years, neither Warner-Lambert nor, to
the knowledge of Warner-Lambert, any of its directors or executive officers: 
(i) has been convicted in a criminal proceeding (excluding traffic violations
or similar misdemeanors) or (ii) was a party to a civil proceeding of a
judicial or administrative body of competent jurisdiction and as a result of
such proceeding was or is subject to a judgment, decree or final order
enjoining future violations of, or prohibiting or mandating activities
subject to, federal or state securities laws or finding any violation with
respect to such laws.

Item 3.          Source and Amount of Funds or Other Consideration.

                 As more fully described in Item 4 of this Statement, Agouron
has granted to Warner-Lambert an option pursuant to which Warner-Lambert has
the right, upon the occurrence of certain events, to purchase from Agouron up
to 19.9% of all outstanding shares of Agouron Common Stock before giving
effect to the Option, for $60 per share, subject to anti-dilution adjustments
(the "Option").  If Warner-Lambert were to exercise the Option in full, the
funds required to purchase the shares of Agouron Common Stock issuable upon
such exercise would be approximately $381.4 million (based on the number of
shares of Agouron Common Stock reported as outstanding as of February 3, 1999). 
It is currently anticipated that such funds would be provided from Warner-
Lambert's working capital or by borrowings from sources yet to be determined.

Item 4.          Purpose of Transaction.

                 Warner-Lambert, Agouron and WLC Acquisition Corporation, a
wholly-owned subsidiary of Warner-Lambert ("Merger Sub"), entered into an
<PAGE>
<PAGE>

Agreement and Plan of Merger, dated as of January 26, 1999 (the "Merger
Agreement"), with respect to the merger of Merger Sub with and into Agouron
as provided for in the Merger Agreement (the "Merger").  In the Merger, each
outstanding share of Agouron Common Stock will be converted into shares of
common stock, par value $1.00 per share, of Warner-Lambert ("Warner-Lambert
Common Stock") at an exchange rate equal to $60.00 divided by the average of
the closing sales prices of Warner-Lambert Common Stock on the New York Stock
Exchange Composite Transactions Tape on each of the 10 consecutive trading
days up to and including the second immediately preceding trading day prior
to the date of Agouron's Stockholders Meeting.  In no event will the exchange
rate be more than 0.9300, or less than 0.8108, of a share of Warner-Lambert
Common Stock for each share of Agouron Common Stock.  As a result of the
Merger, Agouron will become a wholly-owned subsidiary of Warner-Lambert and
its board of directors will consist of the directors of Merger Sub
immediately prior to the Effective Time of the Merger.  Concurrently with and
as a condition to the execution and delivery of the Merger Agreement, Warner-
Lambert and Agouron also entered into a Stock Option Agreement (the "Stock
Option Agreement"), pursuant to which Agouron granted to Warner-Lambert the
Option.

                 Except as described herein and in Item 6 below, neither
Warner-Lambert nor, to the knowledge of Warner-Lambert, any of its directors
or executive officers has any present plan or proposal which relates to, or
could result in, any of the events referred to in paragraphs (a) through (j),
inclusive, of Item 4 of Schedule 13D.  However, subject to Warner-Lambert's
obligations under the agreements referred to above, Warner-Lambert will
continue to review the business of Agouron and may in the future propose that
Agouron take one or more of such actions.

Item 5.          Interest in Securities of Agouron.

                 (a), (b)  Under the Stock Option Agreement, Warner-Lambert
does not have the right to acquire any shares of Agouron Common Stock unless
certain specified events occur.  If the Option were to become exercisable,
Warner-Lambert would be entitled to purchase upon exercise of the Option
(subject to receipt of any necessary regulatory approvals) up to 19.9% of all
outstanding shares of Agouron Common Stock before giving effect to the
Option.  Based on the number of shares of Agouron Common Stock reported as
outstanding as of February 3, 1999, the maximum number of shares into which
the option is exercisable would be 6,357,481 shares of Agouron Common Stock. 
If Warner-Lambert were to exercise the Option, it would have sole power to
vote and, subject to the terms of the Stock Option Agreement, sole power to
direct the disposition of, the shares of Agouron Common Stock covered
thereby.   Because the Option will not be exercisable unless and until
certain specified events occur, Warner-Lambert disclaims beneficial ownership
of any shares of Agouron Common Stock subject to the Option.
<PAGE>
<PAGE>

                 As of the date of this filing, neither Warner-Lambert nor,
to the knowledge of Warner-Lambert, any of its directors or executive
officers beneficially owns any shares of Agouron Common Stock.

                 (c)  Except as stated in Item 4 above, there have not been
any transactions in the Agouron Common Stock effected by or for the account of
Warner-Lambert or, to the knowledge of Warner-Lambert, any of its directors
or executive officers, during the past 60 days. 

                 (d)  In the event that Warner-Lambert were to exercise the
Option, no person, other than Warner-Lambert, would have the right to receive
or the power to direct the receipt of dividends from, or the proceeds from
the sale of, shares of Agouron Common Stock then owned by Warner-Lambert for
its own account.

                 (e)  Not applicable.

Item 6.          Contracts, Arrangements, Undertakings or Relationships with
                 Respect to Securities of Agouron.

                 Except as set forth in response to Items 3, 4 and 5 hereof,
neither Warner-Lambert nor, to the knowledge of Warner-Lambert, any of its
directors or executive officers, has any contracts, arrangements,
understandings or relationships (legal or otherwise) with any person with
respect to any securities of Agouron, including, but not limited to, transfer
or voting of any securities of Agouron, finder's fees, joint ventures, loan
or option arrangements, puts or calls, guarantees of profits, division of
profits or loss or the giving or withholding of proxies.

Item 7.          Material to Be Filed as Exhibits.

         AGREEMENT AND PLAN OF MERGER, dated as of January 26, 1999 (this
"Agreement"), among WARNER-LAMBERT COMPANY, a Delaware corporation ("Warner-
Lambert"), WLC ACQUISITION CORPORATION, a California corporation and a direct
wholly-owned subsidiary of Warner-Lambert ("Merger Sub"), and AGOURON
PHARMACEUTICALS, INC., a California corporation ("Agouron").


                             W I T N E S S E T H:


         WHEREAS, the Boards of Directors of Agouron and Warner-Lambert deem
it advisable and in the best interests of each corporation and its respective
stockholders that Agouron and Warner-Lambert engage in a business combination
in order to advance the long-term strategic business interests of Agouron and
Warner-Lambert;

         WHEREAS, the combination of Agouron and Warner-Lambert shall be
effected by the terms of this Agreement through a merger as outlined below
(the "Merger");

         WHEREAS, in furtherance thereof, the respective Boards of Directors
of Agouron and Warner-Lambert have approved the Merger, upon the terms and
subject to the conditions set forth in this Agreement, pursuant to which each
share of common stock, without par value, of Agouron ("Agouron Common Stock")
issued and outstanding immediately prior to the Effective Time (as defined in
Section 1.3), other than shares owned or held directly or indirectly by
Agouron, will be converted into the right to receive shares of voting common
stock, par value $1.00 per share, of Warner-Lambert ("Warner-Lambert Common
Stock") as set forth in Section 1.8;

         WHEREAS, for Federal income tax purposes, it is intended that the
Merger shall qualify as a reorganization within the meaning of Section 368(a)
of the Internal Revenue Code of 1986, as amended (the "Code"), and the
regulations promulgated thereunder; 

         WHEREAS, for accounting purposes, it is intended that the Merger
shall be accounted for as a pooling of interests transaction under United
States generally accepted accounting principles ("GAAP"); and

         WHEREAS, as a condition to its willingness to enter into this
Agreement, Warner-Lambert has required that, simultaneously with the
execution hereof, Agouron enter into the option agreement ("Stock Option
Agreement"), dated as of the date hereof, with Warner-Lambert, pursuant to
which Agouron is granting to Warner-Lambert an option to purchase up to 19.9%
of Agouron Common Stock on the terms and conditions set forth therein.

         NOW, THEREFORE, in consideration of the foregoing and the respective
representations, warranties, covenants and agreements set forth in this
Agreement and the Stock Option Agreement, and intending to be legally bound
hereby, the parties hereto agree as follows:


                                   ARTICLE I

                                  THE MERGER

         1.1  The Merger.  Upon the terms and subject to the conditions set
forth in this Agreement, and in accordance with the California General
Corporation Law (the "CGCL"), Merger Sub shall be merged with and into
Agouron at the Effective Time.  Immediately, following the Merger, the
separate corporate existence of Merger Sub shall cease and Agouron shall
continue as the surviving corporation (the "Surviving Corporation") under the
name Agouron.

         1.2  Closing.  Subject to the terms and conditions hereof, the
closing of the Merger and the transactions contemplated by this Agreement
(the "Closing") will take place on the second Business Day after the
satisfaction or waiver (subject to applicable law) of the conditions set
forth in Article VI (other than any such conditions which by their terms
cannot be satisfied until the Closing Date, which shall be required to be so
satisfied or waived on the Closing Date), unless another time or date is
agreed to in writing by the parties hereto (the actual time and date of the
Closing being referred to herein as the "Closing Date").  The Closing shall
be held at the offices of Simpson Thacher & Bartlett, 425 Lexington Avenue,
New York, New York, 10017, unless another place is agreed to in writing by
the parties hereto.

         1.3  Effective Time.  At the Closing the parties shall (i) file a
certificate of merger (the "Certificate of Merger") in such form as is
required by and executed in accordance with the relevant provisions of the
CGCL and (ii) make all other filings or recordings required under the CGCL. 
The Merger shall become effective at such time as the Certificate of Merger
is duly filed with the California Secretary of State or at such subsequent
time as Warner-Lambert and Agouron shall agree and as shall be specified in
the Certificate of Merger (the date and time the Merger becomes effective
being the "Effective Time").

         1.4  Effects of the Merger.  At and after the Effective Time, the
Merger will have the effects set forth in the CGCL.  Without limiting the
generality of the foregoing, and subject thereto, at the Effective Time all
the property, rights, privileges, powers and franchises of Agouron and Merger
Sub shall be vested in the Surviving Corporation, and all debts, liabilities


 
<PAGE>
<PAGE>

and duties of Agouron and Merger Sub shall be the debts, liabilities and
duties of the Surviving Corporation.

         1.5  Certificate of Incorporation. The certificate of incorporation
of Agouron, as in effect immediately prior to the Effective Time, shall be
amended and restated as of the Effective Time so as to read in its entirety
in the form set forth as Exhibit 1.5 and, as so amended and restated, shall
be the certificate of incorporation of the Surviving Corporation, until
thereafter changed or amended as provided therein or by applicable law.

         1.6  By-Laws.  At the Effective Time and without any further action
on the part of Agouron and Merger Sub, the By-Laws of Merger Sub shall be the
By-Laws of the Surviving Corporation and thereafter may be amended or
repealed in accordance with their terms or the Certificate of Incorporation
of the Surviving Corporation and as provided by law.

         1.7  Officers and Directors of Surviving Corporation.  The officers
of Agouron as of the Effective Time shall be the officers of the Surviving
Corporation, until the earlier of their resignation or removal or otherwise
ceasing to be an officer or until their respective successors are duly
elected and qualified, as the case may be.  The directors of the Surviving
Corporation as of the Effective Time shall be as provided in Exhibit 1.7,
which individuals will serve as directors of the Surviving Corporation until
the earlier of their resignation or removal or otherwise ceasing to be a
director or until their respective successors are duly elected and qualified.

         1.8  Effect of Merger on Capital Stock.

         (a)  At the Effective Time by virtue of the Merger and without any
action on the part of the holder thereof, each share of Agouron Common Stock
issued and outstanding immediately prior to the Effective Time (other than
shares of Agouron Common Stock held by Agouron, all of which shall be
canceled as provided in Section 1.8(c)) shall be converted into the right to
receive from Warner-Lambert a fraction of a share of Warner-Lambert Common
Stock equal to the Exchange Ratio (as defined in Section 8.11), including the
corresponding percentage of a right to purchase shares of Warner-Lambert's
Series A Preferred Stock (as defined in Section 3.1(b)) pursuant to  the
Warner-Lambert Rights Agreement (as defined in Section 3.1(b)), of Warner-
Lambert Common Stock (together with any cash in lieu of fractional shares of
Warner-Lambert Common Stock to be paid pursuant to Section 2.5, the "Merger
Consideration"). 

         (b)  As a result of the Merger and without any action on the part of
the holders thereof, at the Effective Time, all shares of Agouron Common
Stock shall cease to be outstanding and shall be canceled and retired and
shall cease to exist, and each holder of a certificate which immediately


 
<PAGE>
<PAGE>

prior to the Effective Time represented any such shares of Agouron Common
Stock (a "Certificate") shall thereafter cease to have any rights with
respect to such shares of Agouron Common Stock, except as provided herein or
by law.

         (c)  Each share of Agouron Common Stock issued and owned or held by
Agouron at the Effective Time shall, by virtue of the Merger, cease to be
outstanding and shall be canceled and retired and no stock of Warner-Lambert
or other consideration shall be delivered in exchange therefor.

         (d)  Each share of common stock, no par value, of Merger Sub issued
and outstanding immediately prior to the Effective Time, shall be converted
into issued, outstanding and unchanged as validly issued, fully paid and
nonassessable shares of common stock, no par value, of the Surviving
Corporation as of the Effective Time.

         1.9  Dissenting Agouron Common Shares.  Notwithstanding anything in
this Agreement to the contrary, shares of Agouron Common Stock whose holders
have perfected dissenters' rights under Section 1300 et seq. of the CGCL
("Dissenting Agouron Common Shares") shall not be converted into the right to
receive or be exchangeable for, the Merger Consideration provided for in
Section 1.8 hereof, but, instead, the holders thereof shall be entitled to
payment, by Agouron, of the value of such Dissenting Agouron Common Shares as
agreed upon or determined in accordance with the provisions of Section 1300
et seq. of the CGCL.

         1.10  Agouron Stock Options.

         (a)  On or prior to the Effective Time, Agouron will take all action
necessary such that each Agouron Stock Option (as defined in Section 3.2(b))
that was granted pursuant to the Agouron Stock Option Plans (as defined in
Section 3.2(b)) prior to the Effective Time and which remains outstanding
immediately prior to the Effective Time shall cease to represent a right to
acquire shares of Agouron Common Stock and shall be converted, at the
Effective Time, into an option to acquire, on the same terms and conditions
as were applicable under the Agouron Stock Option, that number of shares of
Warner-Lambert Common Stock determined by multiplying the number of shares of
Agouron Common Stock subject to such Agouron Stock Option by the Exchange
Ratio, rounded, if necessary, to the nearest whole share of Warner-Lambert
Common Stock, at a price per share equal to the per share exercise price
specified in such Agouron Stock Option divided by the Exchange Ratio all
adjusted for any fractional shares eliminated by rounding to ensure the
intrinsic value of the option at consummation is preserved; provided,
however, that in the case of any Agouron Stock Option to which Section 421 of
the Code applies by reason of its qualification under Section 422 of the



<PAGE>
<PAGE>

Code, the option price, the number of shares subject to such option and the
terms and conditions of exercise of such option shall be determined in a
manner consistent with the requirements of Section 424(a) of the Code.

         (b)  As soon as practicable after the Effective Time, Warner-Lambert
shall deliver to the holders of Agouron Stock Options appropriate notices
setting forth such holders' rights pursuant to the Agouron Stock Option Plans
and the agreements evidencing the grants of such Agouron Stock Options shall
continue in effect on the same terms and conditions (subject to the
adjustments required by this Section 1.10 after giving effect to the Merger
and the terms of the Agouron Stock Option Plans).  To the extent permitted by
law, Warner-Lambert shall comply with the terms of the Agouron Stock Option
Plans and shall take such reasonable steps as are necessary or required by,
and subject to the provisions of, such Agouron Stock Option Plans, to have
the Agouron Stock Options which qualified as incentive stock options prior to
the Effective Time continue to qualify as incentive stock options of Warner-
Lambert after the Effective Time.

         (c)  Warner-Lambert shall take all corporate action necessary to
reserve for issuance a sufficient number of shares of Warner-Lambert Common
Stock for delivery upon exercise of Agouron Stock Options in accordance with
this Section 1.10.  Promptly after the Effective Time, Warner-Lambert shall
file a registration statement on Form S-3 or Form S-8, as the case may be (or
any successor or other appropriate forms), with respect to the shares of
Warner-Lambert Common Stock subject to such options and shall use
commercially reasonable efforts to maintain the effectiveness of such
registration statement or registration statements (and maintain the current
status of the prospectus or prospectuses contained therein) for so long as
such options remain outstanding.  With respect to those individuals who
subsequent to the Merger will be subject to the reporting requirements under
Section 16(a) of the Securities Exchange Act of 1934, as amended (the
"Exchange Act"), where applicable, Warner-Lambert shall administer the
Agouron Stock Option Plans in a manner consistent with the exemptions
provided by Rule 16b-3 promulgated under the Exchange Act.

         1.11  Certain Adjustments.  If, between the date of this Agreement
and the Effective Time, the outstanding Warner-Lambert Common Stock or
Agouron Common Stock shall have been changed into a different number of
shares or different class by reason of any reclassification,
recapitalization, stock split, split-up, combination or exchange of shares or
a stock dividend or dividend payable in any other securities shall be
declared with a record date within such period, or any similar event shall
have occurred, the Exchange Ratio shall be appropriately adjusted to provide
to the holders of Agouron Common Stock the same economic effect as
contemplated by this Agreement prior to such event.

                                  ARTICLE II

                           EXCHANGE OF CERTIFICATES

         2.1  Exchange Fund.  Prior to the Effective Time, Warner-Lambert
shall appoint a commercial bank or trust company having net capital of not
less than $100,000,000, or a subsidiary thereof, to act as exchange agent
hereunder for the purpose of exchanging Certificates for the Merger
Consideration (the "Exchange Agent").  At or prior to the Effective Time,
Warner-Lambert shall deposit with the Exchange Agent, in trust for the
benefit of holders of shares of Agouron Common Stock, certificates
representing the Warner-Lambert Common Stock issuable pursuant to Section 1.8
in exchange for outstanding shares of Agouron Common Stock.  Warner-Lambert
agrees to make available to the Exchange Agent from time to time as needed,
cash sufficient to pay cash in lieu of fractional shares pursuant to Section
2.5 and any dividends and other distributions pursuant to Section 2.3.  Any
cash and certificates of Warner-Lambert Common Stock deposited with the
Exchange Agent shall hereinafter be referred to as the "Exchange Fund".

         2.2  Exchange Procedures.  As soon as reasonably practicable after
the Effective Time, the Surviving Corporation shall cause the Exchange Agent
to mail to each holder of a Certificate (i) a letter of transmittal which
shall specify that delivery shall be effected, and risk of loss and title to
the Certificates shall pass, only upon delivery of the Certificates to the
Exchange Agent, and which letter shall be in customary form and have such
other provisions as Warner-Lambert may reasonably specify and (ii)
instructions for effecting the surrender of such Certificates in exchange for
the applicable Merger Consideration.  Upon surrender of a Certificate to the
Exchange Agent together with such letter of transmittal, duly executed and
completed in accordance with the instructions thereto, and such other
documents as may reasonably be required by the Exchange Agent, the holder of
such Certificate shall be entitled to receive in exchange therefor (A) one or
more shares of Warner-Lambert Common Stock (which shall be in uncertificated
book-entry form unless a physical certificate is requested) representing, in
the aggregate, the whole number of shares that such holder has the right to
receive pursuant to Section 1.8 (after taking into account all shares of
Agouron Common Stock then held by such holder) and (B) a check in the amount
equal to the cash that such holder has the right to receive pursuant to the
provisions of this Article II, including cash in lieu of any fractional
shares of Warner-Lambert Common Stock pursuant to Section 2.5 and dividends
and other distributions pursuant to Section 2.3.  No interest will be paid or
will accrue on any cash payable pursuant to Section 2.3 or Section 2.5.  In
the event of a transfer of ownership of Agouron Common Stock which is not
registered in the transfer records of Agouron, one or more shares of Warner-



<PAGE>
<PAGE>

Lambert Common Stock evidencing, in the aggregate, the proper number of
shares of Warner-Lambert Common Stock, a check in the proper amount of cash
in lieu of any fractional shares of Warner-Lambert Common Stock pursuant to
Section 2.5 and any dividends or other distributions to which such holder is
entitled pursuant to Section 2.3, may be issued with respect to such Agouron
Common Stock to such a transferee if the Certificate representing such shares
of Agouron Common Stock is presented to the Exchange Agent, accompanied by
all documents required to evidence and effect such transfer and to evidence
that any applicable stock transfer taxes have been paid.

         2.3  Distributions with Respect to Unexchanged Shares.  No dividends
or other distributions declared or made with respect to shares of Warner-
Lambert Common Stock with a record date after the Effective Time shall be
paid to the holder of any unsurrendered Certificate with respect to the
shares of Warner-Lambert Common Stock that such holder would be entitled to
receive upon surrender of such Certificate and no cash payment in lieu of
fractional shares of Warner-Lambert Common Stock shall be paid to any such
holder pursuant to Section 2.5 until such holder shall surrender such
Certificate in accordance with Section 2.2.  Subject to the effect of
applicable laws, following surrender of any such Certificate, there shall be
paid to such holder of shares of Warner-Lambert Common Stock issuable in
exchange therefor, without interest, (a) promptly after the time of such
surrender, the amount of any cash payable in lieu of fractional shares of
Warner-Lambert Common Stock to which such holder is entitled pursuant to
Section 2.5, and (b) at the appropriate payment date, the amount of dividends
or other distributions with a record date after the Effective Time but prior
to such surrender and a payment date subsequent to such surrender payable
with respect to such shares of Warner-Lambert Common Stock.

         2.4  No Further Ownership Rights in Agouron Common Stock.  All shares
of Warner-Lambert Common Stock issued and cash paid upon conversion of shares
of Agouron Common Stock in accordance with the terms of Article I and this
Article II (including any cash paid pursuant to Section 2.3 or 2.5) shall be
deemed to have been issued or paid in full satisfaction of all rights
pertaining to the shares of Agouron Common Stock.  Until surrendered as
contemplated by this Article II, each Certificate shall be deemed at any time
after the Effective Time to represent only the right to receive upon such
surrender the Merger Consideration.

         2.5  No Fractional Shares of Warner-Lambert Common Stock.

         (a)  No certificates or scrip or shares of Warner-Lambert Common
Stock representing fractional shares of Warner-Lambert Common Stock or book-
entry credit of the same shall be issued upon the surrender for exchange of
Certificates and such fractional share interests will not entitle the owner



<PAGE>
<PAGE>

thereof to vote or to have any rights of a shareholder of Warner-Lambert or a
holder of shares of Warner-Lambert Common Stock.

         (b)  Notwithstanding any other provision of this Agreement, each
holder of shares of Agouron Common Stock exchanged pursuant to the Merger who
would otherwise have been entitled to receive a fraction of a share of
Warner-Lambert Common Stock (after taking into account all Certificates
delivered by such holder) shall receive, in lieu thereof, cash (without
interest) in an amount equal to the product of (i) such fractional part of a
share of Warner-Lambert Common Stock multiplied by (ii) the closing price for
a share of Warner-Lambert Common Stock on the New York Stock Exchange, Inc.
("NYSE") Composite Transactions Tape on the date of the Effective Time or, if
such date is not a Business Day, the Business Day immediately following the
date on which the Effective Time occurs.  As promptly as practicable after
the determination of the amount of cash, if any, to be paid to holders of
fractional interests, the Exchange Agent shall so notify Warner-Lambert, and
Warner-Lambert shall cause the Surviving Corporation to deposit such amount
with the Exchange Agent and shall cause the Exchange Agent to forward
payments to such holders of fractional interests subject to and in accordance
with the terms hereof.

         2.6  Termination of Exchange Fund.  Any portion of the Exchange Fund
which remains undistributed to the holders of Certificates for six months
after the Effective Time shall be delivered to Warner-Lambert or otherwise on
the instruction of  Warner-Lambert and any holders of the Certificates who
have not theretofore complied with this Article II shall thereafter look only
to the Surviving Corporation and Warner-Lambert for the Merger Consideration
with respect to the shares of Agouron Common Stock formerly represented
thereby to which such holders are entitled pursuant to Section 1.8 and
Section 2.2, any cash in lieu of fractional shares of Warner-Lambert Common
Stock to which such holders are entitled pursuant to Section 2.5 and any
dividends or distributions with respect to shares of Warner-Lambert Common
Stock to which such holders are entitled pursuant to Section 2.3.  Any such
portion of the Exchange Fund remaining unclaimed by holders of shares of
Agouron Common Stock five years after the Effective Time (or such earlier
date immediately prior to such time as such amounts would otherwise escheat
to or become property of any Governmental Entity (as defined in Section
3.1(c)(iii)) shall, to the extent permitted by law, become the property of
Warner-Lambert free and clear of any claims or interest of any Person
previously entitled thereto.

         2.7  No Liability.  None of Warner-Lambert, Merger Sub, Agouron, the
Surviving Corporation or the Exchange Agent shall be liable to any Person in
respect of any Merger Consideration from the Exchange Fund delivered to a




<PAGE>
<PAGE>

public official pursuant to any applicable abandoned property, escheat or
similar law.

         2.8  Investment of the Exchange Fund.  The Exchange Agent shall
invest any cash included in the Exchange Fund as directed by Warner-Lambert
on a daily basis.  Any interest and other income resulting from such
investments shall promptly be paid to Warner-Lambert.

         2.9  Lost Certificates.  If any Certificate shall have been lost,
stolen or destroyed, upon the making of an affidavit of that fact by the
Person claiming such Certificate to be lost, stolen or destroyed and, if
required by the Surviving Corporation, the posting by such Person of a bond
in such reasonable amount as the Surviving Corporation may direct as
indemnity against any claim that may be made against it with respect to such
Certificate, the Exchange Agent will deliver in exchange for such lost,
stolen or destroyed Certificate the applicable Merger Consideration with
respect to the shares of Agouron Common Stock formerly represented thereby,
any cash in lieu of fractional shares of Warner-Lambert Common Stock, and
unpaid dividends and distributions on shares of Warner-Lambert Common Stock
deliverable in respect thereof, pursuant to this Agreement.

         2.10  Withholding Rights.  Each of the Surviving Corporation and
Warner-Lambert shall be entitled to deduct and withhold from the
consideration otherwise payable pursuant to this Agreement to any holder of
shares of Agouron Common Stock such amounts as it is required to deduct and
withhold with respect to the making of such payment under the Code and the
rules and regulations promulgated thereunder, or any provision of state,
local or foreign tax law.  To the extent that amounts are so withheld by the
Surviving Corporation or Warner-Lambert, as the case may be, such withheld
amounts shall be treated for all purposes of this Agreement as having been
paid to the holder of the shares of Agouron Common Stock in respect of which
such deduction and withholding was made by the Surviving Corporation or
Warner-Lambert, as the case may be.

         2.11  Further Assurances.  At and after the Effective Time, the
officers and directors of the Surviving Corporation will be authorized to
execute and deliver, in the name and on behalf of Agouron or Merger Sub, any
deeds, bills of sale, assignments or assurances and to take and do, in the
name and on behalf of Agouron or Merger Sub, any other actions and things to
vest, perfect or confirm of record or otherwise in the Surviving Corporation
any and all right, title and interest in, to and under any of the rights,
properties or assets acquired or to be acquired by the Surviving Corporation
as a result of, or in connection with, the Merger.





<PAGE>
<PAGE>

         2.12  Stock Transfer Books.  The stock transfer books of Agouron
shall be closed immediately upon the Effective Time and there shall be no
further registration of transfers of shares of Agouron Common Stock
thereafter on the records of Agouron.  On or after the Effective Time, any
Certificates presented to the Exchange Agent or Warner-Lambert for any reason
shall be converted into the Merger Consideration with respect to the shares
of Agouron Common Stock formerly represented thereby, any cash in lieu of
fractional shares of Warner-Lambert Common Stock to which the holders thereof
are entitled pursuant to Section 2.5 and any dividends or other distributions
to which the holders thereof are entitled pursuant to Section 2.3.


                                  ARTICLE III

                        REPRESENTATIONS AND WARRANTIES

         3.1  Representations and Warranties of Warner-Lambert.  Except as set
forth in the Warner-Lambert Disclosure Schedule delivered by Warner-Lambert
to Agouron prior to the execution of this Agreement (the "Warner-Lambert
Disclosure Schedule") (each section of which qualifies the correspondingly
numbered representation and warranty or covenant to the extent specified
therein) Warner-Lambert represents and warrants to Agouron as follows:

         (a)  Organization, Standing and Power; Subsidiaries.

            (i)  Each of Warner-Lambert and each of its Subsidiaries (as
         defined in Section 8.11) is a corporation duly organized, validly
         existing and in good standing under the laws of its jurisdiction of
         incorporation or organization, has the requisite power and authority
         to own, lease and operate its properties and to carry on its business
         as now being conducted, except where the failure to be so organized,
         existing and in good standing or to have such power and authority
         would not reasonably be expected to have a Material Adverse Effect
         (as defined in Section 8.11) on Warner-Lambert, and is duly qualified
         and in good standing to do business in each jurisdiction in which the
         nature of its business or the ownership or leasing of its properties
         makes such qualification necessary other than in such jurisdictions
         where the failure so to qualify or to be in good standing would not
         reasonably be expected to have a Material Adverse Effect on Warner-
         Lambert.  The copies of the certificate of incorporation and by-laws
         of Warner-Lambert which were previously furnished or made available
         to Agouron are true, complete and correct copies of such documents as
         in effect on the date of this Agreement.





<PAGE>
<PAGE>

            (ii)  Exhibit 21 to Warner-Lambert's Annual Report on Form 10-K
         for the year ended December 31, 1997 includes all the Subsidiaries of
         Warner-Lambert which as of the date of this Agreement are Significant
         Subsidiaries (as defined in Rule 1-02 of Regulation S-X of the SEC). 
         All the outstanding shares of capital stock of, or other equity
         interests in each such Significant Subsidiary have been validly
         issued and are fully paid and nonassessable and are owned directly or
         indirectly by Warner-Lambert, free and clear of all pledges, claims,
         liens, charges, encumbrances and security interests of any kind or
         nature whatsoever (collectively "Liens") and free of any other
         restriction (including any restriction on the right to vote, sell or
         otherwise dispose of such capital stock or other ownership interests)
         other than Liens or restrictions that do not have a Material Adverse
         Effect on Warner-Lambert.  Except as set forth in the Warner-Lambert
         SEC Reports (as defined in Section 3.1(d)), as of the date of this
         Agreement, neither Warner-Lambert nor any of its Subsidiaries
         directly or indirectly owns any equity or similar interest in, or any
         interest convertible into or exchangeable or exercisable for, any
         corporation, partnership, joint venture or other business association
         or entity (other than Subsidiaries), that is or would reasonably be
         expected to be material to Warner-Lambert and its Subsidiaries taken
         as a whole.

         (b)  Capital Structure.

            (i)  As of December 31, 1998, the authorized capital stock of
         Warner-Lambert consisted of (A) 1,200,000,000 shares of Warner-
         Lambert Common Stock of which 821,552,156 shares were outstanding and
         140,429,452 shares were held in the treasury of Warner-Lambert and
         (B) 5,000,000 shares of Preferred Stock, par value $1.00 per share,
         none of which were outstanding and 400,000 shares of which have been
         designated as Series A Junior Participating Preferred Stock (the
         "Series A Preferred Stock") and reserved for issuance upon exercise
         of certain rights as set forth in the Amended and Restated Rights
         Agreement dated as of March 25, 1997 between Warner-Lambert and First
         Chicago Trust Company of New York, as rights agent (the "Warner-
         Lambert Rights Agreement").  Since December 31, 1998 to the date of
         this Agreement, there have been no issuances of shares of the capital
         stock of Warner-Lambert or any other securities of Warner-Lambert
         other than issuances of shares pursuant to options or rights
         outstanding as of December 31, 1998 under the Benefit Plans (as
         defined in Section 8.11) of Warner-Lambert.  All issued and
         outstanding shares of the capital stock of Warner-Lambert are duly
         authorized, validly issued, fully paid and nonassessable, and no
         class of capital stock is entitled to preemptive rights.  There were



<PAGE>
<PAGE>

         outstanding as of December 31, 1998 no options, warrants or other
         rights to acquire capital stock from Warner-Lambert other than
         options, restricted stock and share equivalents representing in the
         aggregate the right to purchase 182,942,041 shares of Warner-Lambert
         Common Stock under the Warner-Lambert Company 1989 Stock Plan, as
         amended to January 27, 1998, Warner-Lambert Company 1992 Stock Plan,
         as amended to January 27, 1998, Warner-Lambert Company 1996 Stock
         Plan, as amended to January 27, 1998 and Restricted Stock Plan for
         Directors of Warner-Lambert Company, as amended to January 28, 1992
         (collectively, the "Warner-Lambert Stock Plans"). 

            (ii)  No bonds, debentures, notes or other indebtedness of
         Warner-Lambert having the right to vote on any matters on which
         holders of capital stock of Warner-Lambert may vote ("Warner-Lambert
         Voting Debt") are issued or outstanding.

            (iii)  Except as otherwise set forth in this Section 3.1(b) and
         as contemplated by Section 1.8 and Section 1.10, as of the date of
         this Agreement, there are no securities, options, warrants, calls,
         rights, commitments, agreements, arrangements or undertakings of any
         kind to which Warner-Lambert or any of its Subsidiaries is a party or
         by which any of them is bound obligating Warner-Lambert to issue,
         deliver or sell, or cause to be issued, delivered or sold, additional
         shares of capital stock or other voting securities of Warner-Lambert
         or obligating Warner-Lambert to issue, grant, extend or enter into
         any such security, option, warrant, call, right, commitment,
         agreement, arrangement or undertaking.  As of the date of this
         Agreement, there are no outstanding obligations of Warner-Lambert to
         repurchase, redeem or otherwise acquire any shares of capital stock
         of Warner-Lambert.

         (c)  Authority; No Conflicts.

            (i)  Warner-Lambert has all requisite corporate power and
         authority to enter into this Agreement and the Stock Option Agreement
         and to consummate the transactions contemplated hereby and thereby,
         including, without limitation, the issuance of the shares of Warner-
         Lambert Common Stock to be issued in the Merger (the "Share
         Issuance").  The execution and delivery of this Agreement and the
         Stock Option Agreement and the consummation of the transactions
         contemplated hereby and thereby have been duly authorized by all
         necessary corporate action on the part of Warner-Lambert.  Each of
         this Agreement and the Stock Option Agreement has been duly executed
         and delivered by Warner-Lambert and constitutes a valid and binding
         agreement of Warner-Lambert, enforceable against it in accordance



<PAGE>
<PAGE>

         with its terms, except as such enforceability may be limited by
         bankruptcy, insolvency, reorganization, moratorium and similar laws
         relating to or affecting creditors generally or by general equity
         principles (regardless of whether such enforceability is considered
         in a proceeding in equity or at law) or by an implied covenant of
         good faith and fair dealing.

            (ii)  The execution and delivery of this Agreement and the Stock
         Option Agreement by Warner-Lambert does not or will not, as the case
         may be, and the consummation by Warner-Lambert of the Merger and the
         other transactions contemplated hereby and thereby will not, conflict
         with, or result in any violation of, or constitute a default (with or
         without notice or lapse of time, or both) under, or give rise to a
         right of termination, amendment, cancellation or acceleration of any
         obligation or the loss of a material benefit under, or the creation
         of a Lien on any assets (any such conflict, violation, default, right
         of termination, amendment, cancellation or acceleration, loss or
         creation, is hereinafter referred to as a "Violation") pursuant to:
         (A) any provision of the certificate of incorporation or by-laws of
         Warner-Lambert or any material Subsidiary of Warner-Lambert or (B)
         except as would not reasonably be expected to have a Material Adverse
         Effect on Warner-Lambert, subject to obtaining or making the
         consents, approvals, orders, authorizations, registrations,
         declarations and filings referred to in paragraph (iii) below, any
         loan or credit agreement, note, mortgage, bond, indenture, lease,
         benefit plan or other agreement, obligation, instrument, permit,
         concession, franchise, license, judgment, order, decree, statute,
         law, ordinance, rule or regulation applicable to Warner-Lambert or
         any Subsidiary of Warner-Lambert, or their respective properties or
         assets.

            (iii)  No consent, approval, order or authorization of, or
         registration, declaration or filing with, any supranational,
         national, state, municipal, local or foreign government, any
         instrumentality, subdivision, court, administrative agency or
         commission or other authority thereof, or any quasi-governmental or
         private body exercising any regulatory, taxing, importing or other
         governmental or quasi-governmental authority (a "Governmental
         Entity"), is required by or with respect to Warner-Lambert or any
         Subsidiary of Warner-Lambert in connection with the execution and
         delivery of this Agreement or the Stock Option Agreement by Warner-
         Lambert or the consummation of the Merger and the other transactions
         contemplated hereby, except for those required under or in relation
         to (A) the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as

         the CGCL with respect to the filing of the Certificate of Merger, (F)
         rules and regulations of the NYSE and the Nasdaq National Market, (G)
         antitrust or other competition laws of other jurisdictions, (H) the
         Consent Decree of Permanent Injunction, dated August 16, 1993 between
         Warner-Lambert and the United States, (I) the Investment Canada Act,
         and (J) such consents, approvals, orders, authorizations,
         registrations, declarations and filings the failure of which to make
         or obtain would not reasonably be expected to have a Material Adverse
         Effect on Warner-Lambert.  Consents, approvals, orders,
         authorizations, registrations, declarations and filings required
         under or in relation to any of the foregoing clauses (A) through (I)
         are hereinafter referred to as "Necessary Consents".

         (d)  Reports and Financial Statements.

            (i)  Warner-Lambert has filed all required registration
         statements, prospectuses, reports, schedules, forms, statements and
         other documents required to be filed by it with the SEC since January
         1, 1998 (collectively, including all exhibits thereto, the "Warner-
         Lambert SEC Reports").  Since such date, no Subsidiary of Warner-
         Lambert is required to file any form, report, registration statement,
         prospectus or other document with the SEC.  None of the Warner-
         Lambert SEC Reports, as of their respective dates (and, if amended or
         superseded by a filing prior to the date of this Agreement or the
         Closing Date, then on the date of such filing), contained or will
         contain any untrue statement of a material fact or omitted or will
         omit to state a material fact required to be stated therein or
         necessary to make the statements therein, in light of the
         circumstances under which they were made, not misleading.  The
         Warner-Lambert SEC Reports together with any public announcements in
         a news release issued by the Dow Jones news service, PR Newswire or
         any equivalent service (collectively, a "Dow Jones News Release")
         made by Warner-Lambert after the date hereof, taken as a whole, as of
         the Effective Time will not contain any 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, in light of the
         circumstances existing as of the Effective Time, not misleading. 
         Each of the financial statements (including the related notes)
         included in the Warner-Lambert SEC Reports presents fairly, in all
         material respects, the consolidated financial position and
         consolidated results of operations and cash flows of Warner-Lambert
         and its Subsidiaries as of the respective dates or for the respective
         periods set forth therein, all in conformity with GAAP applied on a
         consistent basis throughout the periods involved except as otherwise



<PAGE>
<PAGE>

         noted therein, and subject, in the case of the unaudited interim
         financial statements, to normal and recurring adjustments that were
         not or are not expected to be material in amount.  All of such
         Warner-Lambert SEC Reports, as of their respective dates (and as of
         the date of any amendment to the respective Warner-Lambert SEC
         Report), complied as to form in all material respects with the
         applicable requirements of the Securities Act and the Exchange Act
         and the rules and regulations promulgated thereunder.

            (ii)  Except as disclosed in the Warner-Lambert SEC Reports filed
         prior to the date hereof, since December 31, 1997, Warner-Lambert and
         its Subsidiaries have not incurred any liabilities that are of a
         nature that would be required to be disclosed on a balance sheet of
         Warner-Lambert and its Subsidiaries or the footnotes thereto prepared
         in conformity with GAAP, other than (A) liabilities incurred in the
         ordinary course of business or (B) liabilities that would not,
         individually or in the aggregate, reasonably be expected to have a
         Material Adverse Effect on Warner-Lambert.

         (e)  Information Supplied.

            (i)  None of the information supplied or to be supplied by
         Warner-Lambert for inclusion or incorporation by reference in (A) the
         registration statement on Form S-4 to be filed with the SEC by
         Warner-Lambert in connection with the issuance of shares of Warner-
         Lambert Common Stock in connection with the Merger, or any of the
         amendments or supplements thereto (collectively, the "Form S-4")
         will, at the time the Form S-4 is filed with the SEC, at any time it
         is amended or supplemented or at the time it becomes effective under
         the Securities Act, contain any untrue statement of a material fact
         or omit to state any material fact required to be stated therein or
         necessary to make the statements therein not misleading and (B) the
         proxy statement for use relating to the adoption by the stockholders
         of Agouron of this Agreement or any of the amendments or supplements
         thereto (collectively, the "Proxy Statement") will, on the date it is
         first mailed to Agouron stockholders or at the time of the Agouron
         Stockholders Meeting ( as defined in Section 5.1), contain any untrue
         statement of a material fact or omit to state any material fact
         required to be stated therein or necessary in order to make the
         statements therein, in light of the circumstances under which they
         were made, not misleading.  The Form S-4 will comply as to form in
         all material respects with the requirements of the Exchange Act and
         the Securities Act and the rules and regulations of the SEC
         thereunder.

            (ii)  Notwithstanding the foregoing provisions of this Section
         3.1(e), no representation or warranty is made by Warner-Lambert with
         respect to statements made or incorporated by reference in the Form
         S-4 based on information supplied by Agouron for inclusion or
         incorporation by reference therein.

         (f)  Board Approval.  The Board of Directors of Warner-Lambert, by
resolutions duly adopted by unanimous vote at a meeting duly called and held
and not subsequently rescinded or modified in any way (the "Warner-Lambert
Board Approval"), has duly (i) determined that this Agreement and the Stock
Option Agreement, and the Merger are fair to and in the best interests of
Warner-Lambert and its stockholders, and (ii) approved this Agreement and the
Stock Option Agreement, the Merger and the Share Issuance.  To the Knowledge
of Warner-Lambert, no state takeover statute is applicable to the Merger or
the Stock Option Agreement or the other transactions contemplated hereby.

         (g)  Litigation; Compliance with Laws.

            (i)  Except as disclosed in the Warner-Lambert SEC Reports filed
         prior to the date of this Agreement and except for any FDA action
         which may arise out of the Advisory Committee meeting related to
         Rezulin that is currently scheduled for March 26, 1999, there is no
         suit, action, investigation or proceeding pending or, to the
         Knowledge of Warner-Lambert, threatened, against or affecting Warner-
         Lambert or any Subsidiary of Warner-Lambert having, or which would
         reasonably be expected to have a Material Adverse Effect on Warner-
         Lambert, nor is there any judgment, decree, injunction, rule or order
         of any Governmental Entity or arbitrator outstanding against Warner-
         Lambert or any Subsidiary of Warner-Lambert having, or which
         reasonably would be expected to have a Material Adverse Effect on
         Warner-Lambert.

            (ii)  Except as disclosed in the Warner-Lambert SEC Reports filed
         prior to the date of this Agreement and except as would not
         reasonably be expected to have a Material Adverse Effect on Warner-
         Lambert, Warner-Lambert and its Subsidiaries hold all permits,
         licenses, variances, exemptions, orders and approvals of all
         Governmental Entities which are necessary for the operation of the
         businesses of Warner-Lambert and its Subsidiaries, taken as a whole
         (the "Warner-Lambert Permits").  Warner-Lambert and its Subsidiaries
         are in compliance with the terms of the Warner-Lambert Permits,
         except where the failure so to comply would not reasonably be
         expected to have a Material Adverse Effect on Warner-Lambert.  Except
         as disclosed in the Warner-Lambert SEC Reports filed prior to the
         date of this Agreement, the businesses of Warner-Lambert and its



<PAGE>
<PAGE>

         Subsidiaries are not being conducted in violation of, and Warner-
         Lambert has not received any notices of violations with respect to,
         any law, ordinance or regulation of any Governmental Entity, except
         for possible violations which would not reasonably be expected to
         have a Material Adverse Effect on Warner-Lambert.

         (h)  Absence of Certain Changes or Events.  Except for liabilities
incurred in connection with this Agreement and the Stock Option Agreement, or
the transactions contemplated hereby, except as disclosed in the Warner-
Lambert SEC Reports filed prior to the date of this Agreement, except for any
FDA action which may arise out of the Advisory Committee meeting related to
Rezulin that is currently scheduled for March 26, 1999, and except as
permitted by Section 4.2, since January 1, 1999, Warner-Lambert and its
Subsidiaries have conducted their business only in the ordinary course and
there has not been (i) any change, circumstance or event which has had, or
would reasonably be expected to have, a Material Adverse Effect on Warner-
Lambert or (ii) any action taken by Warner-Lambert or any of its Subsidiaries
during the period from January 1, 1999 through the date of this Agreement
that, if taken during the period from the date of this Agreement through the
Effective Time, would constitute a breach of Section 4.2.

         (i)  Environmental Matters.  Except as would not reasonably be
expected to have a Material Adverse Effect on Warner-Lambert, (i) the
operations of Warner-Lambert  and, to the Knowledge of Warner-Lambert, any
entity for which Warner-Lambert may be responsible, has been and is in
compliance with all applicable Environmental Laws (as defined in Section
3.2(j)) and with all Environmental Permits (as defined in Section 3.2(j)),
and (ii) there are no pending or, to the Knowledge of Warner-Lambert,
threatened, actions, suits, claims, investigations or other proceedings
(collectively, "Actions") under or pursuant to Environmental Laws against
Warner-Lambert or, to the Knowledge of Warner-Lambert, any entity for which
Warner-Lambert may be responsible, or involving any real property currently
or, to the Knowledge of  Warner-Lambert, formerly owned, operated or leased
by Warner-Lambert.

         (j)  Brokers or Finders.  No agent, broker, investment banker,
financial advisor or other firm or Person is or will be entitled to any
broker's or finder's fee or any other similar commission or fee in connection
with any of the transactions contemplated by this Agreement or the Stock
Option Agreement, based upon arrangements made by or on behalf of Warner-
Lambert, except Goldman, Sachs & Co. (the "Warner-Lambert Financial
Advisor"), whose fees and expenses will be paid by Warner-Lambert in
accordance with Warner-Lambert's agreement with such firm.

         (k)  Opinion of Warner-Lambert Financial Advisor.  Warner-Lambert has
received the opinion of the Warner-Lambert Financial Advisor, dated the date
of this Agreement, to the effect that, as of such date, the Exchange Ratio is
fair, from a financial point of view, to Warner-Lambert, a copy of which
opinion has been made available to Agouron.

         (l)  Accounting Matters.  To the Knowledge of Warner-Lambert, neither
Warner-Lambert nor any of its affiliates has taken or agreed to take any
action that would prevent Warner-Lambert from accounting for the Merger as a
"pooling of interests".  At or prior to the Closing Date, Warner-Lambert has
received a letter from its independent public accountants addressed to
Warner-Lambert, to the effect that, based upon representations provided by
Warner-Lambert, accounting for the Merger as a pooling of interests under
Opinion 16 of the Accounting Principles Board, applicable SEC rules and
regulations and other authoritative literature is appropriate if the Merger
is consummated and closed as contemplated by this Agreement.

         3.2  Representations and Warranties of Agouron.  Except as set forth
in the Agouron Disclosure Schedule delivered by Agouron to Warner-Lambert
prior to the execution of this Agreement (the "Agouron Disclosure Schedule")
(each section of which qualifies the correspondingly numbered representation
and warranty or covenant to the extent specified therein), Agouron represents
and warrants to Warner-Lambert as follows:

         (a)  Organization, Standing and Power; Subsidiaries.

            (i)  Each of Agouron and each of its Subsidiaries is a
         corporation duly organized, validly existing and in good standing
         under the laws of its jurisdiction of incorporation or organization,
         has the requisite power and authority to own, lease and operate its
         properties and to carry on its business as now being conducted,
         except where the failure to be so organized, existing and in good
         standing or to have such power and authority would not reasonably be
         expected to have a Material Adverse Effect on Agouron and is duly
         qualified and in good standing to do business in each jurisdiction in
         which the nature of its business or the ownership or leasing of its
         properties makes such qualification necessary other than in such
         jurisdictions where the failure so to qualify or to be in good
         standing would not reasonably be expected to have a Material Adverse
         Effect on Agouron.  The copies of the certificate of incorporation
         and by-laws of Agouron which were previously furnished or made
         available to Warner-Lambert are true, complete and correct copies of
         such documents as in effect on the date of this Agreement.

<PAGE>

            (ii)  Exhibit 21 to Agouron's Annual Report on Form 10-K for the
         year ended June 30, 1998, as amended ("Agouron 10-K", together with
         Agouron's Form 10-Q for the quarterly period ended September 30, 1998
         ("Agouron September 98 10Q"), the "Agouron Reports") includes all the
         Subsidiaries of Agouron which as of the date of this Agreement are
         Significant Subsidiaries (as defined in Rule 1-02 of Regulation S-X
         of the SEC).  All the outstanding shares of capital stock of, or
         other equity interests in, each such Significant Subsidiary have been
         validly issued and are fully paid and nonassessable and are owned
         directly or indirectly by Agouron, free and clear of all Liens and
         free of any other restriction (including any restriction on the right
         to vote, sell or otherwise dispose of such capital stock or other
         ownership interests).  Except as set forth in the Agouron Reports,
         neither Agouron nor any of its Subsidiaries directly or indirectly
         owns any equity or similar interest in, or any interest convertible
         into or exchangeable or exercisable for, any corporation,
         partnership, joint venture or other business association or entity,
         that is or would reasonably be expected to be material to Agouron and
         its Subsidiaries taken as a whole.

         (b)  Capital Structure.

            (i)  As of December 31, 1998, the authorized capital stock of
         Agouron consisted of (A) 75,000,000 shares of Agouron Common Stock,
         of which 31,728,847 shares were outstanding and (B) 2,000,000 shares
         of Preferred Stock, without par value, none of which were outstanding
         and 2,000 shares of which have been designated Series B Participating
         Preferred Stock and reserved for issuance upon exercise of the rights
         (the "Rights") distributed to the holders of Agouron Common Stock
         pursuant to the Amended and Restated Rights Agreement dated as of
         November 10, 1998, between Agouron and Chase Mellon Shareholder
         Services, L.L.C., as Rights Agent, as amended (the "Rights
         Agreement").  Since December 31, 1998 to the date of this Agreement,
         there have been no issuances of shares of the capital stock of
         Agouron or any other securities of Agouron other than issuances of
         shares (and accompanying Rights) pursuant to options or rights
         outstanding as of December 31, 1998 under the Benefit Plans of
         Agouron.  All issued and outstanding shares of the capital stock of
         Agouron are duly authorized, validly issued, fully paid and
         nonassessable, and no class of capital stock is entitled to
         preemptive rights.  There were outstanding as of December 31, 1998 no
         options, warrants or other rights to acquire capital stock from
         Agouron other than (x) the Rights and (y) options representing in the
         aggregate the right to purchase no more than 8,747,636 shares of
         Agouron Common Stock (collectively, the "Agouron Stock Options")



<PAGE>
<PAGE>

         under the Agouron Restated 1996 Stock Option Plan, Agouron 1985 Stock
         Option Plan, Agouron 1990 Stock Option Plan, Agouron 1998 Stock
         Option Plan, Agouron Restated Employee Stock Purchase Plan, the
         Alanex Corporation 1993 Stock Plan and the Alanex Corporation 1996
         Equity Incentive Plan and other individual Alanex stock option
         agreements, as each such plan has been amended (collectively, the
         "Agouron Stock Option Plans").  Section 3.2(b) of the Agouron
         Disclosure Schedule sets forth a complete and correct list, as of
         December 31, 1998, of the number of shares of Agouron Common Stock
         subject to Agouron Stock Options or other rights to purchase or
         receive Agouron Common Stock granted under the Benefit Plans of
         Agouron or otherwise, the dates of grant and the exercise prices
         thereof.  No options or warrants or other rights to acquire capital
         stock from Agouron have been issued or granted since December 31,
         1998 to the date of this Agreement, other than pursuant to the Stock
         Option Agreement or as permitted under Section 4.1 of this Agreement.

            (ii)  No bonds, debentures, notes or other indebtedness of
         Agouron having the right to vote on any matters on which stockholders
         may vote ("Agouron Voting Debt") are issued or outstanding.

            (iii)  Except as otherwise set forth in this Section 3.2(b), as
         of the date of this Agreement, there are no securities, options,
         warrants, calls, rights, commitments, agreements, arrangements or
         undertakings of any kind to which Agouron or any of its Subsidiaries
         is a party or by which any of them is bound obligating Agouron or any
         of its Subsidiaries to issue, deliver or sell, or cause to be issued,
         delivered or sold, additional shares of capital stock or other voting
         securities of Agouron or any of its Subsidiaries or obligating
         Agouron or any of its Subsidiaries to issue, grant, extend or enter
         into any such security, option, warrant, call, right, commitment,
         agreement, arrangement or undertaking.  As of the date of this
         Agreement, there are no outstanding obligations of Agouron or any of
         its Subsidiaries to repurchase, redeem or otherwise acquire any
         shares of capital stock of Agouron or any of its Subsidiaries.

         (c)  Authority; No Conflicts.

            (i)  Agouron has all requisite corporate power and authority to
         enter into this Agreement and the Stock Option Agreement and to
         consummate the transactions contemplated hereby and thereby, subject
         in the case of the consummation of the Merger to the adoption of this
         Agreement by the Required Agouron Vote (as defined in Section
         3.2(g)).  The execution and delivery of this Agreement and the Stock
         Option Agreement and the consummation of the transactions



<PAGE>
<PAGE>

         contemplated hereby and thereby have been duly authorized by all
         necessary corporate action on the part of Agouron, subject in the
         case of the consummation of the Merger to the adoption of this
         Agreement by the Required Agouron Vote.  Each of this Agreement and
         the Stock Option Agreement has been duly executed and delivered by
         Agouron and constitutes a valid and binding agreement of Agouron,
         enforceable against it in accordance with its terms, except as such
         enforceability may be limited by bankruptcy, insolvency,
         reorganization, moratorium and similar laws relating to or affecting
         creditors generally or by general equity principles (regardless of
         whether such enforceability is considered in a proceeding in equity
         or at law) or by an implied covenant of good faith and fair dealing.

            (ii)  The execution and delivery of this Agreement and the Stock
         Option Agreement by Agouron does not or will not, as the case may be,
         and the consummation by Agouron of the Merger and the other
         transactions contemplated hereby and thereby will not, conflict with,
         or result in a Violation pursuant to: (A) any provision of the
         certificate of incorporation or by-laws of Agouron or any Subsidiary
         of Agouron or (B) except as would not reasonably be expected to have
         a Material Adverse Effect on Agouron, subject to obtaining or making
         the consents, approvals, orders, authorizations, registrations,
         declarations and filings referred to in paragraph (iii) below, any
         loan or credit agreement, note, mortgage, bond, indenture, lease,
         benefit plan or other agreement, obligation, instrument, permit,
         concession, franchise, license, judgment, order, decree, statute,
         law, ordinance, rule or regulation applicable to Agouron or any
         Subsidiary of Agouron or their respective properties or assets.

            (iii)  No consent, approval, order or authorization of, or
         registration, declaration or filing with, any Governmental Entity is
         required by or with respect to Agouron or any Subsidiary of Agouron
         in connection with the execution and delivery of this Agreement or
         the Stock Option Agreement by Agouron or the consummation of the
         Merger and the other transactions contemplated hereby, except the
         Necessary Consents and such consents, approvals, orders,
         authorizations, registrations, declarations and filings the failure
         of which to make or obtain would not reasonably be expected to have a
         Material Adverse Effect on Agouron.

         (d)  Reports and Financial Statements.

            (i)  Agouron has filed all required registration statements,
         prospectuses, reports, schedules, forms, statements and other
         documents required to be filed by it with the SEC since July 1, 1998



<PAGE>
<PAGE>

         (collectively, including all exhibits thereto, the "Agouron SEC
         Reports").  No Subsidiary of Agouron is required to file any form,
         report, registration statement or prospectus or other document with
         the SEC.  None of the Agouron SEC Reports, as of their respective
         dates (and, if amended or superseded by a filing prior to the date of
         this Agreement or the Closing Date, then on the date of such filing),
         contained or will contain any untrue statement of a material fact or
         omitted or will omit to state a material fact required to be stated
         therein or necessary to make the statements therein, in light of the
         circumstances under which they were made, not misleading.  The
         Agouron SEC Reports together with any public announcements in a Dow
         Jones News Release made by Agouron after the date hereof, taken as a
         whole, as of the Effective Time will not contain any 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, in light
         of the circumstances existing as of the Effective Time, not
         misleading.  Each of the financial statements (including the related
         notes) included in the Agouron SEC Reports presents fairly, in all
         material respects, the consolidated financial position and
         consolidated results of operations and cash flows of Agouron and its
         Subsidiaries as of the respective dates or for the respective periods
         set forth therein, all in conformity with GAAP applied on a
         consistent basis throughout the periods involved except as otherwise
         noted therein, and subject, in the case of the unaudited interim
         financial statements, to normal and recurring adjustments that were
         not or are not expected to be material in amount.  All of such
         Agouron SEC Reports, as of their respective dates (and as of the date
         of any amendment to the respective Agouron SEC Report), complied as
         to form in all material respects with the applicable requirements of

         (n)  Opinion of Agouron Financial Advisor.  Agouron has received the
opinion of PaineWebber Incorporated, dated the date of this Agreement, to the

which opinion has been made available to Warner-Lambert.

         (o)  Accounting Matters.  To the Knowledge of Agouron, neither
Agouron nor any of its affiliates has taken or agreed to take any action that
would prevent Warner-Lambert from accounting for the Merger as a "pooling of
interests".  At or prior to the Closing Date, Agouron has received a letter
from its independent public accountants addressed to Agouron, to the effect
that, based upon representations provided by Agouron, accounting for the
Merger as a pooling of interests under Opinion 16 of the Accounting
Principles Board, applicable SEC rules and regulations and other
authoritative literature is appropriate if the Merger is consummated and
closed as contemplated by this Agreement.

         (p)  Taxes.  Except as previously discussed between the parties,
Agouron and each of its Subsidiaries (which, for the purposes of this Section

deferred Taxes that have not become due; (v)  to the Knowledge of Agouron,

Code or would constitute compensation in excess of the limitation set forth
in Section 162(m) of the Code. As used in clauses (ii), (iii), and (v) of
this Section 3.2(p), the term "Material" shall mean an amount which, in the
aggregate, exceeds $1,000,000.

interest in respect of such penalties and additions, and (ii) the term "Tax
Return" includes all returns and reports (including elections, declarations,

Taxes.

         (q)  Certain Contracts.  As of the date hereof except as filed as
part of the Agouron Reports, neither Agouron nor any of its Subsidiaries is a
party to or bound by (i) any "material contract" (as such term is defined in

effect to the Merger.

         the Code or Sections 409 or 502(i) of ERISA and Agouron has no other

         (u)  Material Contract Defaults.  

           (i)  Agouron has provided or made available to Warner-Lambert
         copies, and has provided a true and correct list to Warner-Lambert,

         leases, policies or other instruments to which it or any of its
         Subsidiaries is a party or by which it or any such Subsidiary is
         bound ("Material Contracts").  Neither Agouron nor any of its
         Subsidiaries is, or has received any notice or has any Knowledge
         that any other party is, in default (or would be in default but for
         the lapse of time or the giving of notice or both) in any respect

         (v)  Insurance.  Agouron has provided or made available to Warner-
Lambert true, correct and complete copies of all policies of insurance to
which Agouron is a party or is a beneficiary or named insured.  Agouron
maintains insurance coverage with reputable insurers in such amounts and
covering such risks as are in accordance with normal industry practice for
companies engaged in businesses similar to that of Agouron (taking into
account the cost and availability of such insurance).

         (w)  Year 2000 Compliance. (i) Except as disclosed on Section 3.2(w)
of the Agouron Disclosure Schedule, all computer hardware, firmware,
software, systems, databases, devices, machinery, equipment and related items
(including embedded microcontrollers in non-computer equipment), embedded
within their products, and/or necessary for Agouron and its Subsidiaries to
carry on their business as presently conducted ("Systems")  are Year 2000
Compliant, or will be Year 2000 Compliant in sufficient time so as to avoid
causing a Material Adverse Effect with respect to Agouron.  For purposes
hereof, "Year 2000 Compliant" means, when used with respect to the Systems,
that such Systems, whether used alone or in combination, will retain full
functionality and, without interruption, will correctly differentiate between
years, in different centuries, and will accurately process date/time data
from, into and between the twentieth and twenty-first centuries, including
leap year calculations and unusual date situations (e.g., 9/9/99).

         (ii)  Agouron and its Subsidiaries have (A) undertaken an assessment
of all Systems that could be adversely affected by a failure to be Year 2000
Compliant on a timely basis, (B) developed a plan and time line for becoming,
and for ensuring that their material suppliers become, Year 2000 Compliant on
a timely basis and (C) to date, implemented such plan in accordance with such
timetable in all material respects.  Based on such inventory, review and
assessment, Agouron hereby represents and warrants to Warner-Lambert that the
estimated total remaining cost of rendering the Systems Year 2000 Compliant
is not expected to exceed $1,000,000.

         (x)  Supply.  As of the date hereof, to the Knowledge of Agouron,
there are no circumstances or facts concerning third party suppliers of
active ingredient, bulk product and finished product to Agouron (as they
relate to Viracept) that would have a material adverse effect on the
continued supply of such materials.

facts relating to the Investigational Compounds or Viracept that would
individually or in the aggregate be reasonably likely to have a material
adverse effect on the development of the Investigational Compounds or the
marketing of Viracept.

         (z)   Generic Drug Enforcement Act.  To the Knowledge of Agouron,
none of the individuals set forth on Exhibit 3.2(z) have ever (i) been

including the Merger, to be accounted for as a pooling of interests under
Opinion 16 of the Accounting Principles Board, applicable SEC rules and
regulations and other authoritative literature, and (ii) such accounting
treatment to be accepted by the SEC.

         5.3  Access to Information.  Upon reasonable notice, each party shall
(and shall cause its Subsidiaries to) afford to the officers, employees,
accountants, counsel, financial advisors and other representatives of the
other party reasonable access during normal business hours, during the period
prior to the Effective Time, to such of its properties, books, contracts,
commitments, records, officers and employees as the other party may
reasonably request and, during such period, such party shall (and shall cause
its Subsidiaries to) furnish promptly to the other party (a) a copy of each
report, schedule, registration statement and other document filed, published,
announced or received by it during such period pursuant to the requirements
of Federal or state securities laws, as applicable (other than documents
which such party is not permitted to disclose under applicable law), and (b)
consistent with its legal obligations, all other information concerning it
and its business, properties and personnel as such other party may reasonably
request; provided, however, that either party may restrict the foregoing
access to the extent that any law, treaty, rule or regulation of any
Governmental Entity applicable to such party requires such party or its
Subsidiaries to restrict access to any properties or information.  The
parties will hold any such information which is non-public in confidence to
the extent required by, and in accordance with, the provisions of the



<PAGE>
<PAGE>

confidential disclosure agreements dated December 15, 1998 and December 23,
1998 between Agouron and Warner-Lambert (the "Confidentiality Agreements"). 
Any investigation by Warner-Lambert or Agouron shall not affect the
representations and warranties of Agouron or Warner-Lambert, as the case may
be.

         5.4  Reasonable Best Efforts.

         (a)  Subject to the terms and conditions of this Agreement, each
party will use its reasonable best efforts to take, or cause to be taken, all
actions and to do, or cause to be done, all things necessary, proper or
advisable under applicable laws and regulations to consummate the Merger and
the other transactions contemplated by this Agreement as soon as practicable
after the date hereof, including (i) preparing and filing as promptly as
practicable all documentation to effect all necessary applications, notices,
petitions, filings, tax ruling requests and other documents and to obtain as
promptly as practicable all consents, waivers, licenses, orders,
registrations, approvals, permits, tax rulings and authorizations necessary
or advisable to be obtained from any third party and/or any Governmental
Entity in order to consummate the Merger or any of the other transactions
contemplated by this Agreement and (ii) taking all reasonable steps as may be
necessary to obtain all such material consents, waivers, licenses,
registrations, permits, authorizations, tax rulings, orders and approvals. 
In furtherance and not in limitation of the foregoing, each party hereto
agrees to make an appropriate filing of a Notification and Report Form
pursuant to the HSR Act and any other Regulatory Law (as defined below) with
respect to the transactions contemplated hereby as promptly as practicable
after the date hereof and to supply as promptly as practicable any additional
information and documentary material that may be requested pursuant to the
HSR Act and any other Regulatory Law and to take all other actions necessary
to cause the expiration or termination of the applicable waiting periods
under the HSR Act as soon as practicable.  Nothing in this Section 5.4(a)
shall require any of Warner-Lambert and its Subsidiaries or Agouron and its
Subsidiaries to sell, hold separate or otherwise dispose of or conduct their
business in a specified manner, or agree to sell, hold separate or otherwise
dispose of or conduct their business in a specified manner, or permit the
sale, holding separate or other disposition of, any assets of Warner-Lambert,
Agouron or their respective Subsidiaries or the conduct of their business in
a specified manner, whether as a condition to obtaining any approval from a
Governmental Entity or any other Person or for any other reason, if such
sale, holding separate or other disposition or the conduct of their business
in a specified manner would reasonably be expected to have a Material
Adverse Effect on Warner-Lambert and its Subsidiaries (including the
Surviving Corporation and its Subsidiaries), taken together, after giving
effect to the Merger.



<PAGE>
<PAGE>

         (b)  Each of Warner-Lambert and Agouron shall, in connection with the
efforts referenced in Section 5.4(a) to obtain all requisite material
approvals and authorizations for the transactions contemplated by this
Agreement under the HSR Act or any other Regulatory Law, use its reasonable
best efforts to (i) cooperate in all respects with each other in connection
with any filing or submission and in connection with any investigation or
other inquiry, including any proceeding initiated by a private party, (ii)
promptly inform the other party of any communication received by such party
from, or given by such party to, the Antitrust Division of the Department of
Justice (the "DOJ") or any other Governmental Entity and of any material
communication received or given in connection with any proceeding by a
private party, in each case regarding any of the transactions contemplated
hereby, and (iii) permit the other party to review any communication given by
it to, and consult with each other in advance of any meeting or conference
with, the DOJ or any such other Governmental Entity or, in connection with
any proceeding by a private party, with any other Person, and to the extent
permitted by the DOJ or such other applicable Governmental Entity or other
Person, give the other party the opportunity to attend and participate in
such meetings and conferences.  For purposes of this Agreement, "Regulatory
Law" means the Sherman Act, as amended, the Clayton Act, as amended, the HSR
Act, the Federal Trade Commission Act, as amended, and all other federal,
state and foreign, if any, statutes, rules, regulations, orders, decrees,
administrative and judicial doctrines and other laws that are designed or
intended to prohibit, restrict or regulate actions having the purpose or
effect of monopolization or restraint of trade or lessening of competition.

         (c)  Subject to the terms and conditions of this Agreement, in
furtherance and not in limitation of the covenants of the parties contained
in Sections 5.4(a) and 5.4(b), if any administrative or judicial action or
proceeding, including any proceeding by a private party, is instituted (or
threatened to be instituted) challenging any transaction contemplated by this
Agreement as violative of any Regulatory Law, each of Warner-Lambert and
Agouron shall cooperate in all respects with each other and use its
respective reasonable best efforts to contest and resist any such action or
proceeding and to have vacated, lifted, reversed or overturned any decree,
judgment, injunction or other order, whether temporary, preliminary or
permanent, that is in effect and that prohibits, prevents or restricts
consummation of the transactions contemplated by this Agreement. 
Notwithstanding the foregoing or any other provision of this Agreement,
nothing in this Section 5.4 shall limit a party's right to terminate this
Agreement pursuant to Article VII.

         (d)  If any objections are asserted with respect to the transactions
contemplated hereby under any Regulatory Law or if any suit is instituted by
any Governmental Entity or any private party challenging any of the



<PAGE>
<PAGE>

transactions contemplated hereby as violative of any Regulatory Law, each of
Warner-Lambert and Agouron shall use its reasonable best efforts to resolve
any such objections or challenge as such Governmental Entity or private party
may have to such transactions under such Regulatory Law so as to permit
consummation of the transactions contemplated by this Agreement.

         (e)  From and after the Effective Time, Warner-Lambert will not take
or cause or permit the Surviving Corporation to take, any action that it
believes would cause the Merger not to qualify as a tax free reorganization
under Section 368(a) of the Code.

         5.5  No Solicitation of Transactions.  Agouron agrees that neither it
nor any of its Subsidiaries nor any of the officers and directors of it or
its Subsidiaries shall, and that it shall direct and cause its and its
Subsidiaries' employees, agents and representatives (including any investment
banker, attorney or accountant retained by it or any of its Subsidiaries) not
to, directly or indirectly, initiate or solicit or take any action designed
to encourage or facilitate (including by way of furnishing information) any
inquiries or the making of any proposal or offer with respect to (i) a
merger, reorganization, share exchange, consolidation, business combination,
recapitalization, liquidation, dissolution or similar transaction involving
it or any of its Subsidiaries, or (ii) any purchase or sale of all or any
significant portion of the assets or 10% or more of the equity securities of
it or any of its Subsidiaries (any such proposal or offer being hereinafter
referred to as an "Acquisition Proposal").  Agouron further agrees that
neither it nor any of its Subsidiaries nor any of the officers and directors
of it or its Subsidiaries shall, and that it shall direct and cause its and
its Subsidiaries' employees, agents and representatives (including any
investment banker, attorney or accountant retained by it or any of its
Subsidiaries) not to, directly or indirectly, have any discussion with or
provide any confidential information or data to any person relating to an
Acquisition Proposal, or engage in any negotiations concerning an Acquisition
Proposal.  Notwithstanding the foregoing, Agouron or its Board of Directors
shall be permitted to (A) to the extent applicable, comply with Rule 14e-2(a)
promulgated under the Exchange Act with regard to an Acquisition Proposal, or
(B) engage in any discussions or negotiations with, or provide any
information to, any person in response to an unsolicited bona fide written
Acquisition Proposal by any such person, if and only to the extent that, in
the case of the actions referred to in clause (B), (i) the Board of Directors
of Agouron concludes in good faith, based on the written advice of its
outside legal counsel, that the provision of such information or the engaging
in such negotiations or discussions is obligated by the directors' fiduciary
duties in accordance with California law, (ii) prior to providing any
information or data to any Person in connection with an Acquisition Proposal
by any such Person, the Board of Directors of Agouron receives from such



<PAGE>
<PAGE>

person an executed confidentiality agreement containing customary terms and
provisions and (iii) prior to providing any information or data to any Person
or entering into discussions or negotiations with any Person, the Board of
Directors of Agouron notifies Warner-Lambert promptly of such inquiries,
proposals or offers received by, any such information requested from, or any
such discussions or negotiations sought to be initiated or continued with,
any of its representatives indicating, in connection with such notice, the
name of such Person and the material terms and conditions of any proposals or
offers.  Agouron agrees that it will keep Warner-Lambert informed, on a
prompt basis, of the status and terms of any such proposals or offers and the
status of any such discussions or negotiations.  Agouron agrees that it will
immediately cease and cause to be terminated any existing activities,
discussions or negotiations with any parties conducted heretofore with
respect to any Acquisition Proposal or similar transaction or arrangement and
will not waive any rights under any confidentiality agreements entered into
with such parties.  Agouron agrees that it will take the necessary steps to
promptly inform the individuals or entities referred to in the first sentence
of this Section 5.5 of the obligations undertaken in this Section 5.5. 

         5.6  Employee Benefits Matters.

         (a)  Continuation and Comparability of Benefits.  From the Effective
Time until December 31, 2000, the Surviving Corporation shall provide
compensation and employee benefits under the Plans (as defined in Section
3.2(r)) to the employees of Agouron and its Subsidiaries employed as of the
Effective Time (except the employees entering into employment agreements and
listed on Exhibit 5.6(a)) (the "Agouron Employees") that are in the aggregate
no less favorable than those provided to such persons pursuant to the Plans
in effect on the date hereof; provided, however, that (i) the Agouron Stock
Purchase Plan shall be terminated as soon as practicable after the Effective
Time and shall not be considered in determining aggregate favorability under
this clause (a), (ii) the Surviving Corporation shall cause the Agouron
401(k) plan to be amended, effective as of the Effective Time (unless
prohibited as a tax-qualification matter) to provide for an additional
matching company contribution on behalf of eligible participants determined
as follows:












<PAGE>
<PAGE>

ADDITIONAL MATCHING                ANNUAL REPORTED EARNINGS PER SHARE
COMPANY CONTRIBUTIONS (made with   GROWTH (determined in the same manner
respect to each eligible           as provided under the Warner-Lambert
participant's elective salary      Savings & Stock Plan)
deferral)

10%                                12.0% or greater, but less than 16.0%
25%                                16.0% or greater, but less than 20.0%
35%                                20.0% or greater

(iii)  the Agouron Employees shall be eligible to enroll in the Warner-
Lambert Retirement Plan as of January 1, 2000, and (iv) the vacation
entitlement of the Agouron Employees accrued as of the Effective Time shall
not be reduced and will apply after the Effective Time with respect to these
Agouron Employees.  Nothing herein shall prohibit any changes to the Plans
that may be (i) required by law (including, without limitation, any
applicable qualification requirements of Section 401(a) of the Code), (ii)
necessary as a technical matter to reflect the transactions contemplated
hereby or (iii) required for Agouron to provide or permit investment in its
securities.  Furthermore, nothing herein shall require Surviving Corporation
to continue any particular Plan or prevent the amendment or termination
thereof (subject to the maintenance, in the aggregate, of the benefits as
provided in the preceding sentence).  Notwithstanding the foregoing, not
later than January 1, 2001, Agouron Employees shall be transitioned to the
compensation-related programs (including salary structure, grades, bonus
policies and programs, salary administration practices, stock option and
other stock-related programs) of Warner-Lambert as determined by Warner-
Lambert, provided, however, that the base salary of any such employee will
not be reduced for a period of two years.  Warner-Lambert will provide non-
qualified Warner-Lambert stock option grants to the management-level
employees of Agouron on or about June 30, 1999, in accordance with Warner-
Lambert's grant guidelines and effective as of January 1, 2000, such
management employees of Agouron will be eligible for stock options on a pro-
rata basis, in accordance with Warner-Lambert's grant guidelines.  For the
fiscal year ending June 30, 1999, the Surviving Corporation will administer
Agouron's bonus program in accordance with the past practice of Agouron,
subject to approval by Warner-Lambert management.  For the period beginning
on July 1, 1999 and ending December 31, 1999, management employees of Agouron
shall be eligible for a bonus on a pro-rata basis reflecting the performance
of Warner-Lambert and such employee, subject to the approval of Warner-
Lambert's management.






<PAGE>
<PAGE>

         (b)  Pre-Existing Limitations; Service Credit.  With respect to any
Benefit Plans in which any Agouron Employees first become eligible to
participate, on or after the Effective Time, and which are plans that the
Agouron Employees did not participate in prior to the Effective Time (the
"New Agouron Plans"), Warner-Lambert shall: (A) waive all pre-existing
conditions, exclusions and waiting periods with respect to participation and
coverage requirements applicable to the Agouron Employees under any New
Agouron Plans in which such employees may be eligible to participate after
the Effective Time; provided that such Agouron Employee and covered family
members were enrolled in comparable coverage under the Benefit Plans of
Agouron on the Effective Time and continuously thereafter until the effective
time of coverage in the New Agouron Plans, and to the extent such waiver is
permissible under the insurance contracts of Warner-Lambert, and (B)
recognize service of the Agouron Employees with Agouron accrued prior to the
Effective Time for purposes of eligibility to participate and vesting credit
in any New Agouron Plan in which such employees may be eligible to
participate after the Effective Time, to the extent such service is taken
into account under the applicable New Agouron Plan.

         (c)  Redundancies.  Agouron Employees whose jobs are eliminated as a
result of the consummation of the transaction contemplated under this
Agreement shall receive severance payments in an amount due under the
severance policy of Warner-Lambert plus a completion bonus if such employee
performs in good faith in the job during a transition period determined by
the Chief Executive Officer of Agouron and approved by Warner-Lambert.  The
amount of the completion bonus shall be based upon base salary and shall be
determined as follows:

Years of service with
Agouron and Warner-Lambert           0-4 years          More than 4 years

Below manager                        3 months               4 months
Manager                              4 months               6 months
Director                             9 months              12 months

         5.7  Directors' and Officers' Indemnification and Insurance.  The
Surviving Corporation shall, and Warner-Lambert shall cause the Surviving
Corporation to, (i) indemnify and hold harmless, and provide advancement of
expenses to, all past and present directors, officers and employees of
Agouron and its Subsidiaries to the same extent such persons are indemnified
or have the right to advancement of expenses as of the date of this Agreement
by Agouron pursuant to Agouron's certificate of incorporation, by-laws and
indemnification agreements, if any, in existence on the date hereof with any




<PAGE>
<PAGE>

directors, officers and employees of Agouron and its Subsidiaries for acts or
omissions occurring at or prior to the Effective Time (including for acts or
omissions occurring in connection with the approval of this Agreement and the
consummation of the transactions contemplated hereby), and (ii) cause to be
maintained for a period of six years after the Effective Time the current
policies of directors' and officers' liability insurance and fiduciary
liability insurance maintained by Agouron (provided that the Surviving
Corporation (or any successor) may substitute therefor policies of at least
the same coverage and amounts containing terms and conditions which are, in
the aggregate, no less advantageous to the insured) with respect to claims
arising from facts or events that occurred on or before the Effective Time;
provided, however, that in no event shall the Surviving Corporation be
required to expend in any one year an amount in excess of 200% of the annual
premiums currently paid by Agouron for such insurance; and, provided,
further, that if the annual premiums of such insurance coverage exceed such
amount, the Surviving Corporation shall be obligated to obtain a policy with
the greatest coverage available for a cost not exceeding such amount.

         5.8  Notification of Certain Matters.  Agouron shall give prompt
notice to Warner-Lambert, and Warner-Lambert shall give prompt notice to
Agouron, of (i) the occurrence or non-occurrence of any event the occurrence
or non-occurrence of which would be likely to cause any representation or
warranty contained in this Agreement to be untrue or inaccurate and (ii) any
failure of Agouron, Warner-Lambert or Merger Sub, as the case may be, to
comply with or satisfy any covenant, condition or agreement to be complied
with or satisfied by it hereunder; provided, however, that the delivery of
any notice pursuant to this Section 5.8 shall not limit or otherwise affect
the remedies available hereunder to the party receiving such notice.

         5.9  Public Announcements.  Warner-Lambert and Agouron shall develop
a joint communications plan and each party shall (i) ensure that all press
releases and other public statements with respect to this Agreement, the
Stock Option Agreement or the transactions contemplated hereby shall be
consistent with such joint communications plan, and (ii) unless otherwise
required by applicable law or by obligations pursuant to any listing
agreement with or rules of any securities exchange, consult with each other
before issuing any press release or otherwise making any public statement
with respect to this Agreement, the Stock Option Agreement or the
transactions contemplated hereby.  In addition to the foregoing, except to
the extent disclosed in or consistent with the Proxy Statement in accordance
with the provisions of Section 5.1, neither Warner-Lambert nor Agouron shall
issue any press release or otherwise make any public statement or disclosure
concerning the other party or the other party's business, financial condition
or results of operations without the consent of the other party, which
consent shall not be unreasonably withheld or delayed.

agreement substantially in the form attached as Exhibit 5.11 hereto (an
"Affiliate Agreement").  Promptly after execution and delivery of this

Directors of Agouron has determined to accept pursuant to Section 5.5.

         5.13  Divisional Stock Proposal.  Agouron agrees not to implement the
proposal (the "Divisional Stock Proposal"), which such proposal would (i)



<PAGE>
<PAGE>

increase the number of shares of authorized common stock to 150,000,000
shares, (ii) create two series of common stock to reflect separately the
performances of Agouron's Oncology Division and its other businesses and

                                  ARTICLE VI

                             CONDITIONS PRECEDENT

         6.1  Conditions to Each Party's Obligation to Effect the Merger.  The
respective obligations of Agouron, Warner-Lambert and Merger Sub to effect
the Merger are subject to the satisfaction or waiver on or prior to the
Closing Date of the following conditions: 

         (a)  Stockholder Approval.  Agouron shall have obtained the Required
Agouron Vote in connection with the adoption of this Agreement by the
stockholders of Agouron.

enacted, issued, promulgated, enforced or entered any statute, rule,
regulation, executive order, decree, judgment, injunction or other order
(whether temporary, preliminary or permanent), in any case which is in effect
and which prevents or prohibits consummation of the Merger or any other
transactions contemplated in this Agreement; and (ii) no Governmental Entity
shall have instituted any action or proceeding (which remains pending at what
would otherwise be the Closing Date) before any United States court or other
governmental body of competent jurisdiction seeking to enjoin, restrain or
otherwise prohibit consummation of the transactions contemplated by this
Agreement.

         (c)  HSR Act.  The waiting period (and any extension thereof)

         (f)  Pooling.  Agouron shall have received and delivered to Warner-
Lambert and Warner-Lambert's independent public accountants, a letter from
its independent public accountants, dated as of the Closing Date, stating
that Agouron qualifies as a "combining company" in accordance with the
criteria set forth in Opinion 16 of the Accounting Principles Board,
applicable SEC rules and regulations and other authoritative literature and
accordingly is a poolable entity.  Warner-Lambert shall have received and
delivered to Agouron, a letter from its independent public accountants, dated
as of the Closing Date, stating that accounting for the Merger as a pooling
of interests under Opinion 16 of the Accounting Principles Board, applicable
SEC rules and regulations and other authoritative literature is appropriate
if the Merger is closed and consummated as contemplated by this Agreement. 
Notwithstanding the foregoing, the satisfaction of this Section 6.1(f) shall
not be a condition to the obligations of a party to effect the Merger if the
failure to satisfy this condition results from any action taken or agreed to
be taken by or on behalf of such party.  

         6.2  Additional Conditions to Obligations of Warner-Lambert and
Merger Sub.  The obligations of Warner-Lambert and Merger Sub to effect the
Merger are subject to the satisfaction of, or waiver by Warner-Lambert, on or

representations and warranties of Agouron set forth in this Agreement (read
without any materiality, Material or Material Adverse Effect qualifications)
shall be true and correct as of the date of this Agreement and as of the
Closing Date as though made on and as of the Closing Date (except to the
extent in either case that such representations and warranties speak as of
another date), except to the extent inaccuracies and breaches therein,
individually or in the aggregate, would not reasonably be expected to have a
Material Adverse Effect on Agouron. Warner-Lambert shall have received a
certificate of the chief executive officer and the chief financial officer of
Agouron to such effect.

         (ii)  There has been no intentional breach of the representations and
warranties of Agouron.

         (b)  Performance of Obligations of Agouron.  (i) Agouron shall have

performed by it under this Agreement at or prior to the Closing Date, except
where the failure to so perform or comply would not reasonably be expected to
have, individually or in the aggregate, a Material Adverse Effect on Agouron,



<PAGE>
<PAGE>

and Warner-Lambert shall have received a certificate of the chief executive
officer and the chief financial officer of Agouron to such effect.

         (ii)  Agouron shall not have intentionally breached any agreement or
covenant required to be performed by Agouron under this Agreement.

of Agouron and Warner-Lambert, to the effect that (i) the Merger will be
treated for federal income tax purposes as a reorganization within the
meaning of Section 368(a) of the Code and (ii) Agouron, Warner-Lambert and
Merger Sub will each be a party to the reorganization within the meaning of

expected to have a Material Adverse Effect on Agouron.

         (e)  Rights Agreement.  No Share Acquisition Date or Distribution
Date shall have occurred pursuant to the Rights Agreement.

         (f)  Dissenting Agouron Shares. The aggregate number of shares of
Agouron Common Stock owned by Persons who have made a demand for purchase
under Section 1301 of the CGCL shall constitute less than 5% of all shares of
Agouron Common Stock outstanding as of the date of the meeting of the Agouron
Shareholders called for the purpose of voting on the Merger.

         6.3  Additional Conditions to Obligations of Agouron.  The
obligations of Agouron to effect the Merger are subject to the satisfaction
of, or waiver by Agouron, on or prior to the Closing Date of the following
additional conditions:

representations and warranties of Warner-Lambert set forth in this Agreement

of the chief executive officer and the chief financial officer of Warner-
Lambert to such effect.

         (ii)  Warner-Lambert shall not have intentionally breached any

incapable of being cured by Warner-Lambert or is not cured within 30 days of
notice of such breach;

         (f)  By Warner-Lambert if prior to the Closing Date there shall have

this Agreement, the Merger or any of the other transactions contemplated
herein or resolved to do so, or (b) approved or recommended an Acquisition
Proposal from a Person (other than Warner-Lambert) or resolved to do so, or
(ii) Agouron materially breaches any of its agreements set forth in Section

the written advice of outside legal counsel, that the directors are obligated


<PAGE>
<PAGE>

by their fiduciary duties in accordance with California law to terminate this
Agreement and to approve the Acquisition Proposal; provided, however, that it
shall be a condition precedent to the termination of this Agreement by
Agouron pursuant to this Section 7.1(h) that Agouron shall have made the
payment of the fee and expenses required by Section 7.3; or 

         (i)  By Warner-Lambert, if any person or group (as defined in Section

         publicly announced and not withdrawn prior to the Agouron
         Stockholders Meeting, or (B) Warner-Lambert terminates this Agreement
         pursuant to Section 7.1(f) if the Board of Directors of Agouron were

         (b)  Within one business day after the termination of this Agreement
pursuant to (i) Section 7.1(c) if an Alternative Transaction or the intention
to propose an Alternative Transaction shall have been publicly announced and

includes all out-of-pocket expenses (including, without limitation, all fees
and expenses of counsel, accountants, investment bankers, experts and
consultants to a party hereto and its affiliates) incurred by a party or on
its behalf in connection with or related to the authorization, preparation,
negotiation, execution and performance of this Agreement and the transactions

         7.4  Amendment.  This Agreement may be amended by the parties hereto,
by action taken or authorized by their respective Boards of Directors, at any



<PAGE>
<PAGE>

time before or after approval of the matters presented in connection with the
Merger by the stockholders of Agouron, but, after any such approval, no
amendment shall be made which by law or in accordance with the rules of any
relevant stock exchange requires further approval by such stockholders
without such further approval.  This Agreement may not be amended except by
an instrument in writing signed on behalf of each of the parties hereto.

         7.5  Extension; Waiver.  At any time prior to the Effective Time, the
parties hereto, by action taken or authorized by their respective Boards of
Directors, may, to the extent legally allowed, (i) extend the time for the
performance of any of the obligations or other acts of the other parties
hereto, (ii) waive any inaccuracies in the representations and warranties
contained herein or in any document delivered pursuant hereto and (iii) waive
compliance with any of the agreements or conditions contained herein.  Any
agreement on the part of a party hereto to any such extension or waiver shall
be valid only if set forth in a written instrument signed on behalf of such
party.  The failure of any party to this Agreement to assert any of its
rights under this Agreement or otherwise shall not constitute a waiver of
those rights.

"without limitation".

counterparts, all of which shall be considered one and the same agreement and
shall become effective when one or more counterparts have been signed by each
of the parties and delivered to the other party, it being understood that

         8.5  Entire Agreement; No Third Party Beneficiaries.

         (a)  This Agreement, the Stock Option Agreement and the

prior agreements and understandings, both written and oral, among the parties
with respect to the subject matter hereof.

         (b)  This Agreement shall be binding upon and inure solely to the
benefit of each party hereto, and nothing in this Agreement, express or

in accordance with the laws of the State of Delaware regardless of the laws
that might otherwise govern under applicable principles of conflicts of laws.

         8.7  Severability.  If any term or other provision of this Agreement

remain in full force and effect so long as the economic or legal substance of
the transactions contemplated hereby is not affected in any manner materially
adverse to any party.  Upon such determination that any term or other
provision is invalid, illegal or incapable of being enforced, the parties
hereto shall negotiate in good faith to modify this Agreement so as to effect
the original intent of the parties as closely as possible in an acceptable
manner in order that the transactions contemplated hereby are consummated as
originally contemplated to the greatest extent possible.

         8.8  Assignment.  Neither this Agreement nor any of the rights,
interests or obligations hereunder shall be assigned by any of the parties

any such assignment without such consent shall be null and void, except that
Merger Sub may assign, in its sole discretion, any or all of its rights,



<PAGE>
<PAGE>

interests and obligations under this Agreement to any direct wholly owned
Subsidiary of Warner-Lambert without the consent of Agouron, but no such
assignment shall relieve Merger Sub of any of its obligations under this
Agreement.  Subject to the preceding sentence, this Agreement will be binding
upon, inure to the benefit of and be enforceable by the parties and their
respective successors and assigns.

         8.9  Submission to Jurisdiction; Waivers.  Each of Warner-Lambert and
Agouron irrevocably agrees that any legal action or proceeding with respect
to this Agreement or for recognition and enforcement of any judgment in
respect hereof brought by the other party hereto or its successors or assigns
may be brought and determined in the Courts of the State of New York and
each of Warner-Lambert and Agouron hereby irrevocably submits with regard to
any such action or proceeding for itself and in respect to its property,
generally and unconditionally, to the nonexclusive jurisdiction of the
aforesaid courts.  Each of Warner-Lambert and Agouron hereby irrevocably
waives, and agrees not to assert, by way of motion, as a defense,
counterclaim or otherwise, in any action or proceeding with respect to this
Agreement, (a) any claim that it is not personally subject to the
jurisdiction of the above-named courts for any reason other than the failure
to lawfully serve process, (b) that it or its property is exempt or immune
from jurisdiction of any such court or from any legal process commenced in
such courts (whether through service of notice, attachment prior to judgment,
attachment in aid of execution of judgment, execution of judgment or
otherwise), and (c) to the fullest extent permitted by applicable law, that
(i) the suit, action or proceeding in any such court is brought in an

EXHIBIT 2   STOCK OPTION AGREEMENT

                             
                              STOCK OPTION AGREEMENT


          STOCK OPTION AGREEMENT, dated as of January 26, 1999 (the
"Agreement"), by and between Agouron Pharmaceuticals, Inc., a California
corporation ("Issuer"), and Warner-Lambert Company, a Delaware corporation
("Grantee").

          WHEREAS, Grantee, Issuer and WLC Acquisition Corporation, a
California corporation and a wholly owned subsidiary of Grantee ("Sub") are
concurrently herewith entering into an Agreement and Plan of Merger, dated as
of the date hereof (the "Merger Agreement"; capitalized terms not defined
herein shall have the meanings set forth in the Merger Agreement), providing
for, among other things, the merger of  Sub with and into Issuer with Issuer
as the surviving corporation; and

          WHEREAS, as a condition and inducement to Grantee's willingness to
enter into the Merger Agreement, Grantee is requiring that Issuer agree, and
Issuer has agreed, to grant Grantee the Option (as defined below).

          NOW, THEREFORE, in consideration of the foregoing and the
respective representations, warranties, covenants and agreements set forth
herein and in the Merger Agreement, Issuer and Grantee agree as follows:

          1.   Grant of Option.  Subject to the terms and conditions set
forth herein, Issuer hereby grants to Grantee an irrevocable option (the
"Option") to purchase up to such number of shares (as adjusted as set forth
herein) (the "Option Shares") of Common Stock, no par value, of Issuer (the
"Issuer Common Stock") as equals 19.9% of the issued and outstanding shares
of Issuer Common Stock at a purchase price of $60.00 per Option Share (the
"Purchase Price").

          2.   Exercise of Option.  (a) If not in material breach of the
Merger Agreement, Grantee may exercise the Option, in whole or in part, at
any time or from time to time following the occurrence of a Purchase Event
(as defined below); provided that, except as otherwise provided herein, the
Option shall terminate and be of no further force and effect upon the
earliest to occur of (i) the Effective Time of the Merger, (ii) 12 months
after the first occurrence of a Purchase Event or (iii) termination of the
Merger Agreement prior to the occurrence of a Purchase Event (unless such
termination itself constitutes a Purchase Event).  Notwithstanding the
termination of the Option, Grantee shall be entitled to purchase those Option
Shares with respect to which it has exercised the Option pursuant to this
Section 2(a) in accordance with the terms hereof prior to the termination of
the Option.  The termination of the Option shall not affect any rights
hereunder which by their terms extend beyond the date of such termination.
<PAGE>
<PAGE>

          (b)  As used herein, a "Purchase Event" means the termination of
the Merger Agreement under any circumstance which would entitle Grantee to
receive a fee from the Issuer pursuant to Section 7.3(a) of the Merger
Agreement.

          (c)  In the event Grantee wishes to exercise the Option, it shall
send to Issuer a written notice (the date of which being herein referred to
as the "Notice Date") specifying (i) the total number of Option Shares it
intends to purchase pursuant to such exercise and (ii) a place and date not
earlier than three business days nor later than 20 business days from such
Notice Date for the closing of such purchase (a "Closing"; and the date of
such Closing, a "Closing Date"); provided that such Closing shall be held
only if (A) such purchase would not otherwise violate or cause the violation
of applicable law (including the HSR Act) and (B) no law, rule or regulation
shall have been adopted or promulgated, and no temporary restraining order,
preliminary or permanent injunction or other order, decree or ruling issued
by a court or other Governmental Entity of competent jurisdiction shall be in
effect, which prohibits delivery of such Option Shares (and the parties
hereto shall use their reasonable best efforts to have any such order,
injunction, decree or ruling vacated or reversed).  If such Closing cannot be
consummated by reason of a restriction set forth in clause (A) or (B) above,
notwithstanding the provisions of Section 2(a), such Closing Date shall be
within 10 business days following the elimination of such restriction.

          3.   Payment and Delivery of Certificates.  (a)  On each Closing
Date, Grantee shall pay to Issuer in immediately available funds by wire
transfer to a bank account designated by Issuer an amount equal to the
Purchase Price multiplied by the Option Shares to be purchased on such
Closing Date.

          (b)  At each Closing, simultaneously with the delivery of
immediately available funds as provided in Section 3(a), Issuer shall deliver
to Grantee a certificate or certificates representing the Option Shares to be
purchased at such Closing, which Option Shares shall be free and clear of all
Liens, and Grantee shall deliver to Issuer a letter agreeing that Grantee
shall not offer to sell or otherwise dispose of such Option Shares in
violation of applicable law or the provisions of this Agreement.  If, at the
time of issuance of any Option Shares pursuant to an exercise of all or part
of the Option hereunder, Issuer shall not have redeemed the Rights, or shall
have issued any similar securities, then each Option Share issued pursuant to
such exercise shall also represent a corresponding Right or new rights with
terms substantially the same as and at least as favorable to Grantee as are
provided under the Rights Agreement or any similar agreement then in effect.

          (c)  Certificates for the Option Shares delivered at each Closing
shall be endorsed with a restrictive legend which shall read substantially as
follows:

                                      -2-

     THE TRANSFER OF THE STOCK REPRESENTED BY THIS CERTIFICATE IS
     SUBJECT TO RESTRICTIONS ARISING UNDER THE SECURITIES ACT OF 1933,
     AS AMENDED, AND PURSUANT TO THE TERMS OF A STOCK OPTION AGREEMENT
     DATED AS OF JANUARY 26, 1999.  A COPY OF SUCH AGREEMENT WILL BE
     PROVIDED TO THE HOLDER HEREOF WITHOUT CHARGE UPON RECEIPT BY THE
     ISSUER OF A WRITTEN REQUEST THEREFOR.

It is understood and agreed that (i) the reference to restrictions arising
under the Securities Act in the above legend shall be removed by delivery of
substitute certificate(s) without such reference if Grantee shall have
delivered to Issuer a copy of a letter from the staff of the SEC, or an
opinion of counsel in form and substance reasonably satisfactory to Issuer
and its counsel, to the effect that such legend is not required for purposes
of the Securities Act and (ii) the reference to restrictions pursuant to this
Agreement in the above legend shall be removed by delivery of substitute
certificate(s) without such reference if the Option Shares evidenced by
certificate(s) containing such reference have been sold or transferred in
compliance with the provisions of this Agreement under circumstances that do
not require the retention of such reference.

          4.   Authorized Stock.  Issuer hereby represents and warrants to
Grantee that Issuer has taken all necessary corporate and other action to
authorize and reserve and to permit it to issue, and, at all times from the
date hereof until the obligation to deliver Issuer Common Stock upon the
exercise of the Option or any Substitute Option (as hereinafter defined)
terminates, will have reserved for issuance, upon exercise of the Option or
any Substitute Option, shares of Issuer Common Stock necessary for Grantee to
exercise the Option or Substitute Option, and Issuer will take all necessary
corporate action to authorize and reserve for issuance all additional shares
of Issuer Common Stock or other securities which may be issued pursuant to
Section 6 upon exercise of the Option or Substitute Option.  The shares of
Issuer Common Stock to be issued upon due exercise of the Option or
Substitute Option, including all additional shares of Issuer Common Stock or
other securities which may be issuable upon exercise of the Option or
Substitute Option pursuant to Section 6, upon issuance pursuant hereto, shall
be duly and validly issued, fully paid and nonassessable, and shall be
delivered free and clear of all Liens, including any preemptive rights of any
stockholder of Issuer.

          5.   Purchase Not for Distribution.  Grantee hereby represents and
warrants to Issuer that any Option Shares or other securities acquired by
Grantee upon exercise of the Option or Substitute Option will not be taken
with a view to the public distribution thereof and will not be transferred or
otherwise disposed of except in a transaction registered or exempt from
registration under the Securities Act.

          6.   Adjustment upon Changes in Capitalization, etc. (a) In the
event of any change in Issuer Common Stock by reason of a reclassification,
recapitalization, stock split, split-up, combination, exchange of shares,
stock dividend, dividend payable in any other securities, or any similar
event, the type and number of shares or securities subject to the Option, and
the Purchase Price therefor, shall be adjusted appropriately, and proper
provision shall be made in the agreements governing such transaction, so that
Grantee shall receive upon exercise of the Option the number and class of
shares or other securities or property that Grantee would have received in
respect of Issuer Common Stock if the Option had been exercised immediately
prior to such event or the record date therefor, as applicable.  If any
additional shares of Issuer Common Stock are issued after the date of this
Agreement (other than pursuant to an event described in the immediately
preceding sentence), the number of shares of Issuer Common Stock subject to
the Option shall be adjusted so that, after such issuance, it equals 19.9% of
the number of shares of Issuer Common Stock then issued and outstanding,
without giving effect to any shares subject to or issued pursuant to the
Option.

          (b)  In the event that Issuer shall enter into an agreement (i) to
consolidate with or merge into any person, other than Grantee or one of its
Subsidiaries, and shall not be the continuing or surviving corporation of
such consolidation or merger, (ii) to permit any person, other than Grantee
or one of its Subsidiaries, to merge into Issuer and Issuer shall be the
continuing or surviving corporation, but, in connection with such merger, the
shares of Issuer Common Stock outstanding immediately prior to the
consummation of such merger shall be changed into or exchanged for stock or
other securities of Issuer or any other person or cash or any other property,
or the shares of Issuer Common Stock outstanding immediately prior to the
consummation of such merger shall after such merger represent less than 50%
of the outstanding voting securities of the merged company, or (iii) to sell
or otherwise transfer all or substantially all of its assets to any person,
other than Grantee or one of its Subsidiaries, then, and in each such case,
the agreement governing such transaction shall make proper provisions so that
the Option shall, upon the consummation of any such transaction and upon the
terms and conditions set forth herein, be converted into, or exchanged for,
an option (the "Substitute Option"), at the election of Grantee, of either
(I) the Acquiring Corporation (as defined below) or (II) any person that
controls the Acquiring Corporation (any such person specified in clause (I)
or (II) being referred to as "Substitute Option Issuer").

          (c)  The Substitute Option shall have the same terms as the Option;
provided that the exercise price therefor and number of shares subject
thereto shall be as set forth in this Section 6 and the repurchase rights
relating thereto shall be as set forth in Section 8; provided, further, that
the Substitute Option shall be exercisable immediately upon issuance without
the occurrence of a Purchase Event; and provided, further, that if the terms

                                      -4-
<PAGE>
<PAGE>

of the Substitute Option cannot, for legal reasons, be the same as the Option
(subject to the variations described in the foregoing provisos), such terms
shall be as similar as possible and in no event less advantageous to Grantee. 
Substitute Option Issuer shall also enter into an agreement with Grantee in
substantially the same form as this Agreement (subject to the variations
described in the foregoing provisos), which shall be applicable to the
Substitute Option.

          (d)  The Substitute Option shall be exercisable for such number of
shares of Substitute Common Stock (as defined below) as is equal to the
Assigned Value (as defined below) multiplied by the number of shares of
Issuer Common Stock for which the Option was theretofore exercisable, divided
by the Average Price (as defined below), rounded up to the nearest whole
share.  The exercise price per share of Substitute Common Stock of the
Substitute Option (the "Substitute Option Price") shall then be equal to the
Purchase Price multiplied by a fraction in which the numerator is the number
of shares of Issuer Common Stock for which the Option was theretofore
exercisable and the denominator is the number of shares of Substitute Common
Stock for which the Substitute Option is exercisable.

          (e)  In no event, pursuant to any of the foregoing paragraphs,
shall the Substitute Option be exercisable for more than 19.9% of the
aggregate of the shares of Substitute Common Stock outstanding prior to
exercise of the Substitute Option.  In the event that the Substitute Option
would be exercisable for more than 19.9% of the aggregate of the shares of
outstanding Substitute Common Stock but for the limitation in the first
sentence of this Section 6(e), Substitute Option Issuer shall make a cash
payment to Grantee equal to the excess of (i) the value of the Substitute
Option without giving effect to the limitation in the first sentence of this
Section 6(e) over (ii) the value of the Substitute Option after giving effect
to the limitation in the first sentence of this Section 6(e).  This
difference in value shall be determined in good faith by a nationally
recognized investment banking firm selected by Grantee.

          (f)  Issuer shall not enter into any transaction described in
Section 6(b) unless the Acquiring Corporation and, if applicable, any
beneficial owner of 50% or more of the outstanding voting stock of the
Acquiring Corporation (after giving effect to the transaction) assume in
writing all the obligations of Issuer hereunder and take all other actions
that may be necessary so that the provisions of this Agreement are given full
force and effect (including, without limitation, any action that may be
necessary so that the holders of the other shares of common stock issued by
Substitute Option Issuer are not entitled to exercise any rights comparable
to the Rights by reason of the issuance or exercise of the Substitute Option
and the shares of Substitute Common Stock are otherwise in no way
distinguishable from or have lesser economic value than other shares of
common stock issued by Substitute Option Issuer (other than any diminution in

                                      -5-
<PAGE>
<PAGE>

value resulting from the fact, if applicable, that the shares of Substitute
Common Stock are restricted securities, as defined in Rule 144 under the
Securities Act or any successor provision)).

          (g)  For purposes of this Agreement, the following terms have the
following meanings:

          (1)  "Acquiring Corporation" means (i) the continuing or surviving
     corporation of a consolidation or merger with Issuer (if other than
     Issuer), (ii) Issuer in a merger in which Issuer is the continuing or
     surviving corporation and (iii) the transferee of all or substantially
     all of Issuer's assets.

          (2)  "Assigned Value" means the highest of (w) the price per share
     of Issuer Common Stock at which a tender offer or exchange offer for
     Issuer Common Stock has been made after the date hereof and prior to the
     consummation of the consolidation, merger or sale referred to in Section
     6(b), (x) the price per share to be paid by any third party or the
     consideration per share to be received by holders of Issuer Common Stock,
     in each case pursuant to the agreement with Issuer with respect to the
     consolidation, merger or sale referred to in Section 6(b), (y) the
     highest closing sales price per share for Issuer Common Stock quoted on
     the NYSE (or if such Issuer Common Stock is not quoted on the NYSE, the
     highest bid price per share as quoted on the National Association of
     Securities Dealers Automated Quotation System or, if the shares of
     Issuer Common Stock are not quoted thereon, on the principal trading
     market on which such shares are traded as reported by a recognized
     source) during the period from the date hereof to the date of exercise
     of the Option and (z) in the event the transaction referred to in
     Section 6(b) is a sale of all or substantially all of Issuer's assets,
     an amount equal to (i) the sum of the price paid in such sale for such
     assets (including assumed liabilities) and the current market value of
     the remaining assets of Issuer, as determined in good faith by a
     nationally recognized investment banking firm selected by Grantee,
     divided by (ii) the number of shares of Issuer Common Stock outstanding
     at such time.  In the event that a tender offer or exchange offer is
     made for Issuer Common Stock or an agreement is entered into for a
     merger or consolidation involving consideration other than cash, the
     value of the securities or other property issuable or deliverable in
     exchange for Issuer Common Stock shall be determined in good faith by a
     nationally recognized investment banking firm selected by Grantee.

          (3)  "Average Price" means the average closing sales price per
     share of a share of Substitute Common Stock quoted on the NYSE (or if
     such Substitute Common Stock is not quoted on the NYSE, the highest bid
     price per share as quoted on the National Association of Securities
     Dealers Automated Quotation System or, if the shares of Substitute

                                      -6-
<PAGE>
<PAGE>

     Common Stock are not quoted thereon, on the principal trading market on
     which such shares are traded as reported by a recognized source) for the
     twenty trading days immediately preceding the fifth business day prior
     to the consolidation, merger or sale in question, but in no event higher
     than the closing price of the shares of Substitute Common Stock on the
     day preceding such consolidation, merger or sale; provided that if
     Substitute Option Issuer is Issuer, the Average Price shall be computed
     with respect to a share of common stock issued by Issuer, the person
     merging into Issuer or by any company which controls such person, as
     Grantee may elect.

          (4)  "Substitute Common Stock" means the shares of capital stock
     (or similar equity interest) with the greatest voting power in respect
     of the election of directors (or persons similarly responsible for the
     direction of the business and affairs) of the Substitute Option Issuer.

          7.   Repurchase of Option and Option Shares.  (a) Notwithstanding
the provisions of Section 2(a), at any time commencing upon the first
occurrence of a Repurchase Event (as defined below) and ending 90 days
thereafter, Issuer (or any successor entity thereof) shall:

               (i)  at the request of Grantee, repurchase from Grantee the
          Option (if and to the extent not previously exercised or
          terminated) at a price equal to the excess, if any, of (x) the
          Applicable Price (as defined below) as of the Section 7 Request
          Date (as defined below) for a share of Issuer Common Stock over (y)
          the Purchase Price (subject to adjustment pursuant to Section
          6(a)), multiplied by the number of shares of Issuer Common Stock
          with respect to which the Option has not been exercised (the
          "Option Repurchase Price"); and

              (ii)  at the request of an owner of Option Shares from time to
          time, repurchase such number of Option Shares as such owner shall
          designate at a price equal to the Applicable Price as of the
          Section 7 Request Date multiplied by the number of Option Shares
          requested to be repurchased by such owner (the "Option Share
          Repurchase Price").

          (b)  If Grantee or an owner of Option Shares exercises its rights
under this Section 7, Issuer shall, within 10 business days after the
Section 7 Request Date, pay the Option Repurchase Price or Option Share
Repurchase Price, as the case may be, in immediately available funds, and
Grantee or such owner, as the case may be, shall surrender to Issuer the
Option or Option Shares, as the case may be.

          (c)  For purposes of this Agreement, the following terms have the
following meanings:

                                      -7-
<PAGE>
<PAGE>

          (i)  "Applicable Price", as of any date, means the highest of (A)
     the highest price per share at which a tender offer or exchange offer
     has been made for shares of Issuer Common Stock after the date hereof
     and on or prior to such date, (B) the highest price per share to be paid
     by any third party for shares of Issuer Common Stock or the
     consideration per share to be received by holders of Issuer Common
     Stock, in each case pursuant to an agreement for an Acquisition Proposal
     with Issuer entered into on or prior to such date or (C) closing sales
     price per share of Issuer Common Stock quoted on the NYSE (or if Issuer
     Common Stock is not quoted on the NYSE, the highest bid price per share
     as quoted on the National Association of Securities Dealers Automated
     Quotations System or, if the shares of Issuer Common Stock are not
     quoted thereon, on the principal trading market on which such shares are
     traded as reported by a recognized source) on the day preceding such
     date.  If the consideration to be offered, paid or received pursuant to
     either of the foregoing clauses (A) or (B) shall be other than in cash,
     the value of such consideration shall be determined in good faith by an
     independent nationally recognized investment banking firm selected by
     Grantee.

         (ii)  "Repurchase Event" means the occurrence of a Purchase Event
     followed by the consummation of any transaction the proposal of which
     would constitute an Acquisition Proposal.

        (iii)  "Section 7 Request Date" means the date on which Grantee or an
     owner of Option Shares exercises its rights under this Section.

          8.   Repurchase of Substitute Option.  (a) At any time after
issuance of the Substitute Option and prior to the expiration of the
Substitute Option, Substitute Option Issuer (or any successor entity thereof)
shall:

           (i) at the request of Grantee, repurchase from Grantee the
     Substitute Option (if and to the extent not previously exercised or
     terminated) at a price equal to the excess, if any, of (x) the Highest
     Closing Price as of the Section 8 Request Date (as defined below) for a
     share of Substitute Common Stock over (y) the Purchase Price (subject to
     adjustment pursuant to Section 6(a)), multiplied by the number of shares
     of Substitute Common Stock with respect to which the Substitute Option
     has not been exercised (the "Substitute Option Repurchase Price"); and

           (ii) at the request of an owner of shares of Substitute Common
     Stock issued upon exercise of the Substitute Option, repurchase such
     number of shares of Substitute Common Stock as such owner shall
     designate at a price equal to the Highest Closing Price as of the
     Section 8 Request Date multiplied by the number of shares of Substitute


                                      -8-
<PAGE>
<PAGE>

     Common Stock requested to be repurchased by such owner (the "Substitute
     Share Repurchase Price"). 

          (b)  If Grantee or an owner of shares of Substitute Common Stock
issued upon exercise of the Substitute Option exercises its rights under this
Section 8, Substitute Option Issuer shall, within 10 business days after the
Section 8 Request Date, pay the Substitute Option Repurchase Price or
Substitute Share Repurchase Price, as the case may be, in immediately
available funds, and Grantee or such owner, as the case may be, shall
surrender to Issuer the Option or shares of Substitute Common Stock, as the
case may be.

          (c)  For purposes of this Agreement, the following terms have the
following meanings:

          (i) "Highest Closing Price" means the highest closing sales price
     for shares of Substitute Common Stock quoted on the NYSE (or if the
     Substitute Common Stock is not quoted on the NYSE, the highest bid price
     per share as quoted on the National Association of Securities Dealers
     Automated Quotations System or, if the shares of Substitute Common Stock
     are not quoted thereon, on the principal trading market on which such
     shares are traded as reported by a recognized source) during the six-
     month period preceding the Section 8 Request Date; and

          (ii) "Section 8 Request Date" means the date on which Grantee or an
     Owner exercises its rights under this Section.

          9.   Registration Rights.  Issuer shall, if requested by Grantee or
any owner of Option Shares (collectively with Grantee, the "Owners") at any
time and from time to time within three years of the first exercise of the
Option, as expeditiously as possible prepare and file up to two registration
statements under the Securities Act if such registration is necessary in
order to permit the sale or other disposition of any or all shares of
securities that have been acquired by or are issuable to such Owners upon
exercise of the Option in accordance with the intended method of sale or
other disposition stated by such Owners, including a "shelf" registration
statement under Rule 415 under the Securities Act or any successor provision,
and Issuer shall use its best efforts to qualify such shares or other
securities under any applicable state securities laws.  Issuer shall use all
reasonable efforts to cause each such registration statement to become
effective, to obtain all consents or waivers of other parties which are
required therefor and to keep such registration statement effective for such
period not in excess of 180 days from the day such registration statement
first becomes effective as may be reasonably necessary to effect such sale or
other disposition.  The obligations of Issuer hereunder to file a
registration statement and to maintain its effectiveness may be suspended for
one or more periods of time not exceeding 30 days in the aggregate if the

                                      -9-
<PAGE>
<PAGE>

Board of Directors of Issuer shall have determined that the filing of such
registration statement or the maintenance of its effectiveness would require
disclosure of nonpublic information that would materially and adversely
affect Issuer.  Any registration statement prepared and filed under this
Section 9, and any sale covered thereby, shall be at Issuer's expense except
for underwriting discounts or commissions, brokers' fees and the fees and
disbursements of Owners' counsel related thereto.  The Owners shall provide
all information reasonably requested by Issuer for inclusion in any
registration statement to be filed hereunder.  If during the time period
referred to in the first sentence of this Section 9 Issuer effects a
registration under the Securities Act of Issuer Common Stock for its own
account or for any other stockholders of Issuer (other than on Form S-4 or
Form S-8, or any successor form), it shall allow the Owners the right to
participate in such registration, and such participation shall not affect the
obligation of Issuer to effect two registration statements for the Owners
under this Section 9; provided that, if the managing underwriters of such
offering advise Issuer in writing that in their opinion the number of shares
of Issuer Common Stock requested to be included in such registration exceeds
the number which can be sold in such offering, Issuer shall include the
shares requested to be included therein by  the Owners pro rata with the
shares intended to be included therein by Issuer.  In connection with any
registration pursuant to this Section 9, Issuer and the Owners shall provide
each other and any underwriter of the offering with customary
representations, warranties, covenants, indemnification and contribution in
connection with such registration.

          10.  Listing; Reasonable Best Efforts.  (a) If Issuer Common Stock
or any other securities to be acquired upon exercise of the Option are then
listed on the NYSE or any other securities exchange or market, Issuer, upon
the request of any Owner, will promptly file an application to list the
shares of Issuer Common Stock or other securities to be acquired upon
exercise of the Option on the NYSE or such other securities exchange or
market and will use its best efforts to obtain approval of such listing as
soon as practicable.

          (b) Issuer will use its reasonable best efforts to take, or cause
to be taken, all actions and to do, or cause to be done, all things
necessary, proper or advisable under applicable laws and regulations to
permit the exercise of the Option or the Substitute Option in accordance with
the terms and conditions hereof, as soon as practicable after the date
hereof, including making any appropriate filing of pursuant to the HSR Act
and any other Regulatory Law, supplying as promptly as practicable any

          11.  Limitation of Grantee Profit.  (a) Notwithstanding any other
provision herein, in no event shall Grantee's Total Profit (as defined below)
exceed $60 million (the "Maximum Profit") and, if it otherwise would exceed
such amount, Grantee, at its sole discretion, shall either (i) reduce the
number of shares subject to the Option, (ii) deliver to Issuer for
cancellation shares of Issuer Common Stock (or other securities into which
such Option Shares are converted or exchanged), (iii) pay cash to Issuer, or
(iv) any combination of the foregoing, so that Grantee's actually realized
Total Profit shall not exceed the Maximum Profit after taking into account
the foregoing actions.

          (b)  For purposes of this Agreement, "Total Profit" shall mean: 
(i) the aggregate amount of (A) any excess of (x) the net cash amounts
received by Grantee pursuant to a sale of Option Shares (or securities into
which such shares are converted or exchanged) to any unaffiliated third party
within 12 months after the exercise of the Option, over (y) the Grantee's
aggregate purchase price for such Option Shares (or other securities), plus
(B) any amounts received by Grantee on the transfer of the Option (including
amounts payable to Grantee pursuant to Section 7), plus (C) any equivalent
amounts with respect to the Substitute Option (including Section 6(e)
hereof), plus (D) any amounts received by Grantee pursuant to Section 7.3(a)
of the Merger Agreement, minus (ii) the sum of amounts of any cash previously
paid to Issuer pursuant to this Section 11 plus the value of the Option
Shares (or other securities) previously delivered to Issuer for cancellation
pursuant to this Section 11.

          (c)  Notwithstanding any other provision of this Agreement, nothing
in this Agreement shall affect the ability of Grantee to receive, nor relieve
Issuer's obligation to pay, any payment provided for in Section 7.3 of the
Merger Agreement; provided that if and to the extent the Total Profit
received by Grantee would exceed the Maximum Profit following receipt of such
payment, Grantee shall be obligated to comply with the terms of Section 11(a)
within 15 days of the latest of (i) the date of receipt of such payment, (ii)
the date of receipt of the net cash by Grantee pursuant to the sale of Option
Shares (or securities into which such Option Shares are converted or
exchanged) to any unaffiliated party within 12 months after the exercise of
this Option with respect to such Option Shares, (iii) the date of receipt of
net cash from disposition of the Option and (iv) the date of receipt of
equivalent amounts pursuant to the sale of the Substitute Option or shares of
Substitute Common Stock (or other securities into which such Substitute
Common Stock is converted or exchanged).

          (d)  For purposes of Section 11(a) and clause (ii) of Section
11(b), the value of any Option Shares delivered to Issuer shall be the
Assigned Value of such Option Shares and the value of any Substitute Common
Stock delivered to Issuer shall be the Highest Closing Price of such
Substitute Common Stock.

          12.  Loss, Theft, Etc. of Agreement.  This Agreement (and the
Option granted hereby) is exchangeable, without expense, at the option of
Grantee, upon presentation and surrender of this Agreement at the principal
office of Issuer for other Agreements providing for Options of different
denominations entitling the holder thereof to purchase in the aggregate the
same number of shares of Issuer Common Stock purchasable hereunder.  The
terms "Agreement" and "Option" as used herein include any other Agreements
and related Options for which this Agreement (and the Option granted hereby)
may be exchanged.  Upon receipt by Issuer of evidence reasonably satisfactory
to it of the loss, theft, destruction or mutilation of this Agreement, and
(in the case of loss, theft or destruction) of reasonably satisfactory
indemnification, and upon surrender and cancellation of this Agreement, if
mutilated, Issuer will execute and deliver a new Agreement of like tenor and
date.  Any such new Agreement executed and delivered shall constitute an
additional contractual obligation on the part of Issuer, whether or not the
Agreement so lost, stolen, destroyed or mutilated shall at any time be
enforceable by anyone.

          13.  Miscellaneous.  (a)  Expenses.  Except as otherwise provided
in Section 9 hereof or in the Merger Agreement, each of the parties hereto
shall bear and pay all Expenses incurred by it or on its behalf in connection
with the transactions contemplated hereunder, including fees and expenses of
its own financial consultants, investment bankers, accountants and counsel.

          (b)   Waiver and Amendment.  Any provision of this Agreement may be
waived at any time by the party that is entitled to the benefits of such
provision.  This Agreement may not be modified, amended, altered or
supplemented except upon the execution and delivery of a written agreement
executed by the parties hereto.

          (c)  Entire Agreement; No Third-Party Beneficiary; Severability. 
Except as otherwise set forth in the Merger Agreement, this Agreement,
together with the Merger Agreement, (a) constitutes the entire agreement and
supersedes all prior agreements and understandings, both written and oral,
between the parties with respect to the subject matter hereof and (b) is not
intended to confer upon any person other than the parties hereto any rights
or remedies hereunder.  If any term, provision, covenant or restriction of
this Agreement is held by a court of competent jurisdiction or a federal or
state regulatory agency to be invalid, void or unenforceable, the remainder
of the terms, provisions, covenants and restrictions of this Agreement shall
remain in full force and effect and shall in no way be affected, impaired or
invalidated.  If for any reason such court or regulatory agency determines
that the Option does not permit Grantee to acquire, or does not require
Issuer (or Substitute Option Issuer) to repurchase, the full number of shares
of Issuer Common Stock (or Substitute Common Stock) as provided in Sections 2
and 7 (or in the case of Substitute Common Stock Sections 2 and 8), as
adjusted pursuant to Section 6, it is the express intention of Issuer to

                                     -12-
<PAGE>
<PAGE>

allow Grantee to acquire or to require Issuer to repurchase such lesser
number of shares as may be permissible without any amendment or modification
hereof.

          (D)  GOVERNING LAW.  THIS AGREEMENT SHALL BE GOVERNED AND CONSTRUED
IN ACCORDANCE WITH THE LAWS OF THE STATE OF DELAWARE REGARDLESS OF THE LAWS
THAT MIGHT OTHERWISE GOVERN UNDER APPLICABLE PRINCIPLES OF CONFLICTS OF LAWS.

          (e)  Descriptive Headings.  The descriptive headings contained
herein are for convenience of reference only and shall not affect in any way
the meaning or interpretation of this Agreement.

          (f)  Notices.  All notices and other communications hereunder shall
be in writing and shall be deemed given as set forth in Section 8.2 of the
Merger Agreement.

                 (g)  Counterparts.  This Agreement and any amendments
hereto may be executed in two counterparts, each of which shall be considered
one and the same agreement and shall become effective when both counterparts
have been signed by each of the parties and delivered to the other party, it
being understood that both parties need not sign the same counterpart.

                 (h)  Assignment.  Grantee may assign this Agreement in
whole to any affiliate of Grantee at any time.  Except as provided in the
next sentence and by operation of law, Grantee may not, without the prior
written consent of Issuer (which shall not be unreasonably withheld), assign
this Agreement to any other person.  Upon the occurrence of a Purchase Event,
Grantee may sell, transfer, assign or otherwise dispose of, in whole at any
time, its rights and obligations hereunder.  In the case of any sale,
transfer, assignment or disposition of this Option, Issuer shall do all
things reasonably necessary to facilitate such transaction.  This Agreement
shall not be assignable by Issuer except by operation of law.  Subject to the
preceding sentence, this Agreement shall be binding upon, inure to the
benefit of and be enforceable by the parties and their respective successors
and assigns.

                 (i)  Representations and Warranties.  The representations
and warranties contained in Sections 3.1(a) and 3.2(a) of the Merger
Agreement, and, to the extent they relate to this Stock Option Agreement, in
Sections 3.1(c), (f) and (i) and 3.2(c), (f), (l) and (m) of the Merger
Agreement, are incorporated herein by reference.

                 (j)  Rights Plan.  Until the Option has been exercised or
terminated in full and Grantee no longer holds any Option Shares, Issuer
shall not amend, modify or waive any provision of the Rights Agreement (the
"Rights Agreement") or take any other action which would cause Grantee or any
of its "Affiliates" or "Associates" to become an "Acquiring Person", or which

                                     -13-
<PAGE>
<PAGE>

would cause a "Stock Acquisition Date" or "Distribution Date", any event
specified in Section 11(a)(ii) or 13 of the Rights Agreement or any similar
event with respect to the Rights to occur, by reason of the existence or
exercise (in whole or in part) of the Option, the beneficial ownership by
Grantee or any of its "Affiliates" or "Associates" of any of the Option
Shares, or the consummation of the other transactions contemplated hereby
(all terms in quotes are used as defined in the Rights Agreement).  This
covenant shall also apply to any Substitute Option or shares of Substitute
Common Stock issued in respect thereof, and to any securities into which any
Option Shares or Substitute Common Stock are converted or exchanged.

                 (k)  Further Assurances.  In the event of any exercise
of the Option by Grantee, Issuer and Grantee shall execute and deliver all
other documents and instruments and take all other action that may be
reasonably necessary in order to consummate the transactions provided for by
such exercise.

                 (l)  Enforcement.  The parties agree that irreparable
damage would occur in the event that any of the provisions of this Agreement
were not performed in accordance with their specific terms.  It is
accordingly agreed that the parties shall be entitled to specific performance
of the terms hereof, this being in addition to any other remedy to which they
are entitled at law or in equity.  Both parties further agree to waive any
requirement for the securing or posting of any bond in connection with the
obtaining of any such equitable relief and that this provision is without
prejudice to any other rights that the parties hereto may have for any
failure to perform this Agreement.

                 (m)  Submission to Jurisdiction; Waivers.  Each of
Issuer and Grantee irrevocably agrees that any legal action or proceeding
with respect to this Agreement or for recognition and enforcement of any
judgment in respect hereof brought by the other party hereto or its
successors or assigns may be brought and determined in the Courts of the
State of New York, and each of Issuer and Grantee hereby irrevocably submits
with regard to any such action or proceeding for itself and in respect to its
property, generally and unconditionally, to the nonexclusive jurisdiction of
the aforesaid courts.  Each of Issuer and Grantee hereby irrevocably waives,
and agrees not to assert, by way of motion, as a defense, counterclaim or
otherwise, in any action or proceeding with respect to this Agreement, (a)
any claim that it is not personally subject to the jurisdiction of the above-
named courts for any reason other than the failure to lawfully serve process,
(b) that it or its property is exempt or immune from jurisdiction of any such
court or from any legal process commenced in such courts (whether through
service of notice, attachment prior to judgment, attachment in aid of
execution of judgment, execution of judgment or otherwise), and (c) to the
fullest extent permitted by applicable law, that (i) the suit, action or
proceeding in any such court is brought in an inconvenient forum, (ii) the

                                     -14-
<PAGE>
<PAGE>

venue of such suit, action or proceeding is improper and (iii) this
Agreement, or the subject matter hereof, may not be enforced in or by such
courts.
