 ITEM 5.  OTHER EVENTS.

           On February 6, 2000, the stock options that had been granted by
 Warner-Lambert Company ("Warner-Lambert") and American Home Products
 Corporation ("AHP") to one another in connection with the execution of the
 Agreement and Plan of Merger, dated as of November 3, 1999, among
 Warner-Lambert, AHP and a subsidiary of AHP (the "AHP Merger Agreement")
 were cancelled without consideration.

           Thereafter, AHP terminated the AHP Merger Agreement in
 accordance with its terms. In connection with the termination of the AHP
 Merger Agreement, Warner-Lambert paid to AHP a termination fee of $1.8
 billion pursuant to the terms of the AHP Merger Agreement.

           Warner-Lambert, Pfizer Inc. ("Pfizer") and  Seminole Acquisition
Sub Corp., a wholly owned subsidiary of Pfizer ("Merger Sub"), entered into
an Agreement and Plan of Merger, dated as of February 6, 2000 (the "Pfizer
Merger Agreement"). Pursuant to the Pfizer Merger Agreement and subject to
the terms and conditions set forth therein, Merger Sub will be merged with
and into Warner-Lambert, with Warner-Lambert being the surviving
corporation of such merger (the "Merger"). At the Effective Time (as
defined in the Pfizer Merger Agreement) of the Merger, each issued and
outstanding share of common stock, par value $1.00 per share, of Warner-
Lambert will be converted into 2.75 shares of common stock, par value $0.05
per share, of Pfizer. The combined company after the Merger will be named
Pfizer. The Merger is subject to various conditions, including, among other
things, receipt of the necessary approvals of Warner-Lambert's and Pfizer's
stockholders, the receipt of required regulatory approvals and the Merger
being accounted for as a pooling-of-interests.

           A copy of the Pfizer Merger Agreement is attached hereto as
 Exhibit 2.1 and is incorporated herein by reference.  The foregoing
 description is qualified in its entirety by reference to the full text of
 such exhibits.

           AGREEMENT AND PLAN OF MERGER, dated as of February 6, 2000 (this
 "Agreement"), among PFIZER INC., a Delaware corporation ("Pfizer"),
 SEMINOLE ACQUISITION SUB CORP., a Delaware corporation and a direct wholly-
 owned subsidiary of Pfizer ("Merger Sub"), and WARNER-LAMBERT COMPANY, a
 Delaware corporation ("Warner-Lambert").

                            W I T N E S S E T H:

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

           WHEREAS, the combination of Warner-Lambert and Pfizer 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 Warner-Lambert and Pfizer 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, par value $1.00 per share, of Warner-
 Lambert ("Warner-Lambert Common Stock") issued and outstanding immediately
 prior to the Effective Time (as defined in Section 1.3), other than shares
 owned or held directly by Pfizer or directly or indirectly by Warner-
 Lambert, will be converted into the right to receive shares of common
 stock, par value $0.05 per share, of Pfizer ("Pfizer 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; and

           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").

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

                                    ARTICLE I

                    THE MERGER; CERTAIN RELATED MATTERS

           1.1  THE MERGER.  Upon the terms and subject to the conditions
 set forth in this Agreement, and in accordance with the Delaware General
 Corporation Law (the "DGCL"), Merger Sub shall be merged with and into
 Warner-Lambert at the Effective Time.  Following the Merger, the separate
 corporate existence of Merger Sub shall cease and Warner-Lambert shall
 continue as the surviving corporation (the "Surviving Corporation").

           1.2  CLOSING.  Upon the terms and subject to the conditions set
 forth in Article VI and the termination rights set forth in Article VII,
 the closing of the Merger (the "Closing") will take place on the first
 Business Day after the satisfaction or waiver (subject to applicable law)
 of the conditions (excluding conditions that, by their nature, cannot be
 satisfied until the Closing Date) set forth in Article VI, unless this
 Agreement has been theretofore terminated pursuant to its terms or 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 Cadwalader,
 Wickersham & Taft, 100 Maiden Lane, New York, New York, 10038, unless
 another place is agreed to in writing by the parties hereto.

           1.3  EFFECTIVE TIME.  As soon as practicable following the
 satisfaction or waiver (subject to applicable law) of the conditions set
 forth in Article VI, 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
 DGCL and (ii) make all other filings or recordings required under the DGCL.
 The Merger shall become effective at such time as the Certificate of Merger
 is duly filed with the Delaware Secretary of State or at such subsequent
 time as Pfizer and Warner-Lambert 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 DGCL.  Without limiting the
 generality of the foregoing, and subject thereto, at the Effective Time all
 the property, rights, privileges, powers and franchises of Warner-Lambert
 and Merger Sub shall be vested in the Surviving Corporation, and all debts,
 liabilities and duties of Warner-Lambert and Merger Sub shall become the
 debts, liabilities and duties of the Surviving Corporation.

           1.5  CERTIFICATE OF INCORPORATION.  (a)  The certificate of
 incorporation of Warner-Lambert, as in effect immediately prior to the
 Effective Time, shall be the certificate of incorporation of the Surviving
 Corporation, until thereafter changed or amended as provided therein or by
 applicable law.

           (b)  Pfizer will use its reasonable best efforts to amend the
 certificate of incorporation of Pfizer effective as of the Effective Time,
 as set forth in Exhibit 1.5(b) hereto, to increase the number of directors
 on the Pfizer Board of Directors to not less than ten nor more than twenty-
 four (the "Board Amendment").  If the Board Amendment is approved by
 Pfizer's Stockholders at the Pfizer Stockholders Meeting, Pfizer shall use
 its reasonable best efforts to appoint to the Pfizer Board of Directors
 effective as of the Effective Time eight individuals currently serving on
 the Warner-Lambert Board of Directors, each such individual to be appointed
 to the class of the Pfizer Board of Directors determined by Pfizer after
 taking into account the advice and recommendation of the Transition
 Planning Team referred to in the letter mentioned in Section 1.7 herein.
 In the event that the Board Amendment is not approved by Pfizer's
 stockholders at the Pfizer Stockholder Meeting, then Pfizer will take all
 action to expand its Board of Directors to 18 members effective as of the

 Effective Time and appoint three current Warner-Lambert directors to the
 Pfizer Board of Directors  and use its reasonable best efforts to appoint
 three additional current Warner-Lambert directors to the Pfizer Board of
 Directors as each new vacancy on the Pfizer Board of Directors occurs
 following the Effective Time.

           1.6  BYLAWS.  (a)  The bylaws of Warner-Lambert, as in effect
 immediately prior to the Effective Time, shall be the bylaws of the
 Surviving Corporation until thereafter changed or amended as provided
 therein or by applicable law.

           (b)  The bylaws of Pfizer shall be amended effective as of the
 Effective Time to the effect provided in Exhibit 1.6(b).  The amendment to
 the bylaws of Pfizer is referred to in this Agreement as the "Pfizer Bylaw
 Amendment."

           1.7  OFFICERS AND DIRECTORS OF SURVIVING CORPORATION AND PFIZER.
 Upon consummation of the Merger, the officers and directors of Pfizer shall
 be as provided in the letter to the Chairman and the Chief Executive
 Officer of Warner-Lambert, dated February 6, 2000, from the Chairman and
 Chief Executive Officer of Pfizer.

           1.8  EFFECT 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 Warner-Lambert Common Stock issued and outstanding
 immediately prior to the Effective Time (other than shares of Warner-
 Lambert Common Stock owned by Pfizer or Merger Sub or held by Warner-
 Lambert, all of which shall be canceled as provided in Section 1.8(c)),
 together with the associated Warner-Lambert Rights, shall be converted into
 2.75 validly issued, fully paid and non-assessable shares of Pfizer Common
 Stock (the "Exchange Ratio") and the associated Pfizer Rights (together
 with any cash in lieu of fractional shares of Pfizer 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 Warner-Lambert
 Common Stock (together with the associated Warner-Lambert Rights) shall
 cease to be outstanding and shall be canceled and retired and shall cease
 to exist, and each holder of a certificate which immediately prior to the
 Effective Time represented any such shares of Warner-Lambert Common Stock
 (a "Certificate") shall thereafter cease to have any rights with respect to
 such shares of Warner-Lambert Common Stock, except as provided herein or by
 law.

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

           (d)  At the Effective Time, by virtue of the Merger and without
 any action on the part of the holder thereof, each share of common stock,
 par value $0.01 per share, of Merger Sub issued and outstanding immediately
 prior to the Effective Time, shall be converted into one validly issued,
 fully paid and non-assessable share of common stock, par value $1.00 per
 share, of the Surviving Corporation.

           1.9  WARNER-LAMBERT STOCK OPTIONS AND OTHER EQUITY-BASED AWARDS.
 (a)  Each Warner-Lambert Stock Option (as defined in Section 3.2(b)) that
 was granted pursuant to the Warner-Lambert 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 Warner-Lambert 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 Warner-Lambert
 Stock Option (but taking into account any changes thereto, including the
 acceleration thereof, provided for in the Warner-Lambert Stock Option Plans
 or in such option by reason of this Agreement or the transactions
 contemplated hereby), that number of shares of Pfizer Common Stock
 determined by multiplying the number of shares of Warner-Lambert Common
 Stock subject to such Warner-Lambert Stock Option by the Exchange Ratio,
 rounded, if necessary, to the nearest whole share of Pfizer Common Stock,
 at a price per share (rounded to the nearest one-hundredth of a cent) equal
 to the per share exercise price specified in such Warner-Lambert Stock
 Option divided by the Exchange Ratio; provided, however, that in the case
 of any Warner-Lambert Stock Option to which Section 421 of the Code applies
 by reason of its qualification under Section 422 of the 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. On or prior
 to the Effective Time, Warner-Lambert will take all actions necessary such
 that all Warner-Lambert Stock Options outstanding prior to the Effective
 Time under the Warner-Lambert Stock Option Plans are treated in accordance
 with the immediately preceding sentences, including, but not limited to,
 precluding the holder of each Warner-Lambert Stock Option from receiving
 any cash payments in respect of such Option in connection with the Merger.

           (b)  Pursuant to the Warner-Lambert Stock Option Plans,
 restricted shares of Warner-Lambert Common Stock granted pursuant thereto
 which are outstanding immediately prior to the Effective Time shall become
 fully vested and free of restrictions as of the Effective Time in
 accordance with the terms thereof.  Each such award shall be converted, as
 of the Effective Time, into a number of shares of Pfizer Common Stock equal
 to the product of (1) the number of shares subject to the award and (2) the
 Exchange Ratio; and the number of shares of Pfizer Common Stock as so
 determined shall be delivered to the holder of each such award as soon as
 practicable following the Effective Time.  On or prior to the Effective
 Time, Warner-Lambert will take all actions necessary such that awards of
 restricted shares are treated in accordance with the immediately preceding
 sentences, including, but not limited to, precluding each holder from
 receiving any cash payments in respect of such awards in connection with
 the Merger.

           (c)  All Warner-Lambert stock credits (including any fractions
 thereof) in each stock account which is governed by the terms of Warner-
 Lambert's 1996 Stock Plan ("Warner-Lambert Stock Credits") shall, as of the
 Effective Time, be converted into a number of Pfizer stock credits equal to
 the product of (1) the number of Warner-Lambert Stock Credits in such stock
 account immediately prior to the Effective Time and (2) the Exchange Ratio,
 and shall otherwise remain subject to the terms and conditions applicable
 to such Warner-Lambert Stock Credits.  On or prior to the Effective Time,
 Warner-Lambert shall take all actions necessary to ensure that such Warner-
 Lambert Stock Credits are converted in accordance with the immediately
 preceding sentence, including, but not limited to, precluding each holder
 from receiving any cash payments in respect of such stock account in
 connection with the Merger.

           (d)  Prior to the Effective Time and pursuant to the authority
 reserved by Warner-Lambert under the Warner-Lambert Stock Option Plans,
 Warner-Lambert will take all actions necessary to preclude the holder of
 any stock appreciation right or limited stock appreciation right granted
 separately or in tandem with the awards described in Section 1.9(a) or (b)
 hereof from receiving any cash payments in respect of such awards in
 connection with the Merger.

           (e)  As soon as practicable after the Effective Time, Pfizer
 shall deliver to the holders of Warner-Lambert Stock Options appropriate
 notices setting forth such holders' rights pursuant to the Warner-Lambert
 Stock Option Plans (including that, in connection with the Merger and
 pursuant to the terms of the Warner-Lambert Stock Option Plans, the Warner-
 Lambert Stock Options of such holders have become fully vested and
 exercisable) and the agreements evidencing the grants of such Warner-
 Lambert Stock Options shall continue in effect on the same terms and
 conditions (subject to the adjustments required by this Section 1.9 after
 giving effect to the Merger and the terms of the Warner-Lambert Stock
 Option Plans).  To the extent permitted by law, Pfizer shall comply with
 the terms of the Warner-Lambert Stock Option Plans and shall take such
 reasonable steps as are necessary or required by, and subject to the
 provisions of, such Warner-Lambert Stock Option Plans, to have the Warner-
 Lambert Stock Options which qualified as incentive stock options prior to
 the Effective Time continue to qualify as incentive stock options of Pfizer
 after the Effective Time.

           (f)  Pfizer shall take all corporate action necessary to reserve
 for issuance a sufficient number of shares of Pfizer Common Stock for
 delivery upon exercise of Warner-Lambert Stock Options or in connection
 with restricted shares or in connection with the settlement of stock
 accounts in accordance with this Section 1.9.  Promptly after the Effective
 Time, Pfizer 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 Pfizer Common Stock subject to such options or
 restricted shares or stock accounts 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, restricted
 shares or stock accounts 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, Pfizer shall administer the
 Warner-Lambert Stock Option Plans in a manner consistent with the
 exemptions provided by Rule 16b-3 promulgated under the Exchange Act.

           1.10 CERTAIN ADJUSTMENTS.  If, between the date of this Agreement
 and the Effective Time, the outstanding Pfizer Common Stock or Warner-
 Lambert 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 Warner-Lambert Common Stock the same economic
 effect as contemplated by this Agreement prior to such event.

           1.11 ASSOCIATED RIGHTS.  References in Article I and Article II
 of this Agreement to Warner-Lambert Common Stock shall include, unless the
 context requires otherwise, the associated Warner-Lambert Rights and
 references in Article I and Article II of this Agreement to Pfizer Common
 Stock shall include, unless the context requires otherwise, the associated
 Pfizer Rights.


                                 ARTICLE II

                          EXCHANGE OF CERTIFICATES

           2.1  EXCHANGE FUND.  Prior to the Effective Time, Pfizer shall
 appoint a commercial bank or trust company reasonably acceptable to Warner-
 Lambert having net capital of not less than $300,000,000, 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, Pfizer shall deposit with the Exchange Agent,
 in trust for the benefit of holders of shares of Warner-Lambert Common
 Stock, certificates representing the Pfizer Common Stock issuable pursuant
 to Section 1.8 in exchange for outstanding shares of Warner-Lambert Common
 Stock.  Pfizer 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 Pfizer Common Stock deposited
 with the Exchange Agent shall hereinafter be referred to as the "Exchange
 Fund."

           2.2  EXCHANGE PROCEDURES.  Promptly 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 proper delivery of the Certificates to the Exchange
 Agent, and which letter shall be in customary form and have such other
 provisions as Pfizer may reasonably specify (such letter to be reasonably
 acceptable to Warner-Lambert prior to the Effective Time) 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 Pfizer 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 Warner-Lambert 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 Pfizer 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 Warner-Lambert Common Stock which is not registered in the
 transfer records of Warner-Lambert, one or more shares of Pfizer Common
 Stock evidencing, in the aggregate, the proper number of shares of Pfizer
 Common Stock, a check in the proper amount of cash in lieu of any
 fractional shares of Pfizer 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 Warner-Lambert Common
 Stock to such a transferee if the Certificate representing such shares of
 Warner-Lambert 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
 Pfizer 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 Pfizer 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 Pfizer 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 Pfizer 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 Pfizer Common Stock to
 which such holder is entitled pursuant to Section 2.5 and the amount of
 dividends or other distributions with a record date after the Effective
 Time theretofore paid with respect to such whole shares of Pfizer Common
 Stock, 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 Pfizer Common Stock.

           2.4  NO FURTHER OWNERSHIP RIGHTS IN WARNER-LAMBERT COMMON STOCK.
 All shares of Pfizer Common Stock issued and cash paid upon conversion of
 shares of Warner-Lambert 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 Warner-Lambert
 Common Stock.

           2.5  NO FRACTIONAL SHARES OF PFIZER COMMON STOCK.  (a)  No
 certificates or scrip or shares of Pfizer Common Stock representing
 fractional shares of Pfizer 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 thereof to vote or to
 have any rights of a stockholder of Pfizer or a holder of shares of Pfizer
 Common Stock.

           (b)  Notwithstanding any other provision of this Agreement, each
 holder of shares of Warner-Lambert Common Stock exchanged pursuant to the
 Merger who would otherwise have been entitled to receive a fraction of a
 share of Pfizer 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 Pfizer Common Stock multiplied by (ii) the closing price for a
 share of Pfizer 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.

           (c)  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 Pfizer, and Pfizer 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 Pfizer or otherwise
 on the instruction of Pfizer, and any holders of the Certificates who have
 not theretofore complied with this Article II shall thereafter look only to
 Pfizer for the Merger Consideration with respect to the shares of Warner-
 Lambert 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 Pfizer Common Stock to which such holders are entitled
 pursuant to Section 2.5 and any dividends or distributions with respect to
 shares of Pfizer 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 Warner-Lambert 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 the Surviving Corporation free and clear of
 any claims or interest of any Person previously entitled thereto.

           2.7  NO LIABILITY.  None of Pfizer, Merger Sub, Warner-Lambert,
 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 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 Pfizer on a
 daily basis; provided, that no such gain or loss thereon shall affect the
 amounts payable to Warner-Lambert stockholders pursuant to Article I and
 the other provisions of this Article II.  Any interest and other income
 resulting from such investments shall promptly be paid to Pfizer.

           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 Warner-Lambert Common Stock formerly
 represented thereby, any cash in lieu of fractional shares of Pfizer Common
 Stock, and unpaid dividends and distributions on shares of Pfizer Common
 Stock deliverable in respect thereof, pursuant to this Agreement.

           2.10 WITHHOLDING RIGHTS.  Each of the Surviving Corporation and
 Pfizer shall be entitled to deduct and withhold from the consideration
 otherwise payable pursuant to this Agreement to any holder of shares of
 Warner-Lambert 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 Pfizer, 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 Warner-Lambert Common Stock in respect
 of which such deduction and withholding was made by the Surviving
 Corporation or Pfizer, 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 Warner-Lambert or Merger
 Sub, any deeds, bills of sale, assignments or assurances and to take and
 do, in the name and on behalf of Warner-Lambert 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.

           2.12 STOCK TRANSFER BOOKS.  The stock transfer books of Warner-
 Lambert shall be closed immediately upon the Effective Time and there shall
 be no further registration of transfers of shares of Warner-Lambert Common
 Stock thereafter on the records of Warner-Lambert.  On or after the
 Effective Time, any Certificates presented to the Exchange Agent or Pfizer
 for any reason shall be converted into the Merger Consideration with
 respect to the shares of Warner-Lambert Common Stock formerly represented
 thereby (including any cash in lieu of fractional shares of Pfizer 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.

           2.13 AFFILIATES.  Notwithstanding anything to the contrary
 herein, to the fullest extent permitted by law, no certificates
 representing shares of Pfizer Common Stock or cash shall be delivered to a
 Person who may be deemed an "affiliate" of Warner-Lambert in accordance
 with Section 5.13 hereof for purposes of Rule 145 under the Securities Act
 of 1933, as amended (the "Securities Act"), or for purposes of qualifying
 the Merger for pooling-of-interests accounting treatment under Opinion 16
 of the Accounting Principles Board and applicable rules and regulations of
 the Securities and Exchange Commission (the "SEC") until such Person has
 executed and delivered an Affiliate Agreement (as defined in Section 5.13)
 to Pfizer.


                                 ARTICLE III

                       REPRESENTATIONS AND WARRANTIES

           3.1  REPRESENTATIONS AND WARRANTIES OF PFIZER.  Except as set
 forth in the Pfizer disclosure schedule delivered by Pfizer to Warner-
 Lambert prior to the execution of this Agreement (the "Pfizer Disclosure
 Schedule") (each section of which qualifies the correspondingly numbered
 representation and warranty or covenant), Pfizer represents and warrants to
 Warner-Lambert as follows:

           (a)  Organization, Standing and Power; Subsidiaries.

           (i)  Each of Pfizer and each of its Subsidiaries (as defined in
      Section 8.11) is 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 failures to be so organized, existing and in good standing
      or to have such power and authority, in the aggregate, would not
      reasonably be expected to have a Material Adverse Effect on Pfizer,
      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 failures so to qualify or to be
      in good standing, in the aggregate, would not reasonably be expected
      to have a Material Adverse Effect on Pfizer.  The copies of the
      certificate of incorporation and bylaws of Pfizer 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.

           (ii) Exhibit 21 to Pfizer's Annual Report on Form 10K for the
      year ended December 31, 1998 includes all the Subsidiaries of Pfizer
      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 non-assessable and are, except as set forth in
      Exhibit 21, owned directly or indirectly by Pfizer, 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), except for restrictions imposed by applicable
      securities laws.  Except as set forth in the Pfizer SEC Reports (as
      defined in Section 3.1(d)) filed prior to the date hereof, neither
      Pfizer 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 Pfizer and its Subsidiaries taken as a whole.

           (b)  Capital Structure.

           (i)  As of December 31, 1999, the authorized capital stock of
      Pfizer consisted of (A) 9,000,000,000 shares of Pfizer Common Stock of
      which 3,846,907,771 shares were outstanding and 413,166,530 shares
      were held in the treasury of Pfizer and (B) 12,000,000 shares of
      Preferred Stock, no par value, of which 3,000,000 shares have been
      designated Series A Junior Preferred Stock and reserved for issuance
      upon exercise of the rights (the "Pfizer Rights") distributed to the
      holders of Pfizer Common Stock pursuant to the Rights Agreement, dated
      as of October 6, 1997 between Pfizer and ChaseMellon Shareholder
      Services, L.L.C. (the "Pfizer Rights Agreement").  Since December 31,
      1999 to the date of this Agreement, there have been no issuances of
      shares of the capital stock of Pfizer or any other securities of
      Pfizer other than issuances of shares pursuant to options or rights
      outstanding as of December 31, 1999 under the Benefit Plans (as
      defined in Section 8.11(b)) of Pfizer.  All issued and outstanding
      shares of the capital stock of Pfizer are, and when shares of Pfizer
      Common Stock are issued in the Merger or upon exercise of stock
      options converted in the Merger pursuant to Section 1.9, such shares
      will be, duly authorized, validly issued, fully paid and non-
      assessable and free of any preemptive rights.  There were outstanding
      as of December 31, 1999 no options, warrants or other rights to
      acquire capital stock from Pfizer other than (x) the Pfizer Rights and
      (y) options, restricted stock and other rights to acquire capital
      stock from Pfizer representing in the aggregate the right to purchase
      approximately 273,104,687 shares of Pfizer Common Stock (collectively,
      the "Pfizer Stock Options") under Pfizer's Stock and Incentive Plan,
      Pfizer's Performance-Contingent Share Award Program,  Pfizer's Annual
      Retainer Unit Award Plan (for non-employee Directors), Pfizer's
      Nonfunded Deferred Compensation and Unit Award Plan for Non-Employee
      Directors and Pfizer's Restricted Stock Plan for Non-Employee
      Directors (collectively, the "Pfizer Stock Option Plans").
      Section 3.1(b) of the Pfizer Disclosure Schedule sets forth a complete
      and correct list, as of December 31, 1999, of the number of shares of
      Pfizer Common Stock subject to Pfizer Stock Options or other rights to
      purchase or receive Pfizer Common Stock granted under the Pfizer
      Benefit Plans or otherwise, the dates of grant and the exercise prices
      thereof.  No options or warrants or other rights to acquire capital
      stock from Pfizer have been issued or granted since December 31, 1999
      to the date of this Agreement.

           (ii) No bonds, debentures, notes or other indebtedness of Pfizer
      having the right to vote on any matters on which holders of capital
      stock of Pfizer may vote ("Pfizer 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 1.9, 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 Pfizer or any of its Subsidiaries is a party or by which
      any of them is bound obligating Pfizer 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
      Pfizer or any of its Subsidiaries or obligating Pfizer 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 Pfizer or any of its Subsidiaries to
      repurchase, redeem or otherwise acquire any shares of capital stock of
      Pfizer or any of its Subsidiaries.

           (c)  Authority; No Conflicts.

           (i)  Pfizer has all requisite corporate power and authority to
      enter into this Agreement and to consummate the transactions
      contemplated hereby, subject to obtaining the requisite stockholder
      approval of the issuance of the shares of Pfizer Common Stock to be
      issued in the Merger (the "Share Issuance") and the Board Amendment
      (collectively, the "Pfizer Stockholder Approval").  The execution and
      delivery of this Agreement and the consummation of the transactions
      contemplated hereby have been duly authorized by all necessary
      corporate action on the part of Pfizer, subject to obtaining the
      Pfizer Stockholder Approval.  This Agreement has been duly executed
      and delivered by Pfizer and constitutes a valid and binding agreement
      of Pfizer, 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).

           (ii) The execution and delivery of this Agreement by Pfizer does
      not or will not, as the case may be, and the consummation by Pfizer of
      the Merger and the other transactions contemplated hereby 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, or result by its terms in the, termination, amendment,
      cancellation or acceleration of any obligation or the loss of a
      material benefit under, or the creation of a lien, pledge, security
      interest, charge or other encumbrance on, or the loss of, any assets,
      including Intellectual Property (any such conflict, violation,
      default, right of termination, amendment, cancellation or
      acceleration, loss or creation, a "Violation") pursuant to:  (A) any
      provision of the certificate of incorporation or bylaws of Pfizer or
      any material Subsidiary of Pfizer, or (B) except as, in the aggregate,
      would not reasonably be expected to have a Material Adverse Effect (as
      defined in Section 8.11(g)) on Pfizer, 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 Pfizer or any Subsidiary
      of Pfizer 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 Pfizer or any Subsidiary of Pfizer in connection
      with the execution and delivery of this Agreement by Pfizer 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 amended (the
      "HSR Act"), (B) state securities or "blue sky" laws (the "Blue Sky
      Laws"), (C) the Securities Act, (D) the Exchange Act, (E) the DGCL
      with respect to the filing of the Certificate of Merger, (F) rules and
      regulations of the NYSE, (G) antitrust or other competition laws of
      other jurisdictions, and (H) such consents, approvals, orders,
      authorizations, registrations, declarations and filings the failures
      of which to make or obtain, in the aggregate, would not reasonably be
      expected to have a Material Adverse Effect on Pfizer.  Consents,
      approvals, orders, authorizations, registrations, declarations and
      filings required under or in relation to any of the foregoing
      clauses (A) through (G) are hereinafter referred to as "Necessary
      Consents."

           (d)  Reports and Financial Statements.

           (i)  Pfizer 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 "Pfizer SEC
      Reports").  No Subsidiary of Pfizer is required to file any form,
      report, registration statement, prospectus or other document with the
      SEC.  None of the Pfizer 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.  Each of the
      financial statements (including the related notes) included in the
      Pfizer SEC Reports presents fairly, in all material respects, the
      consolidated financial position and consolidated results of operations
      and cash flows of Pfizer and its consolidated Subsidiaries as of the
      respective dates or for the respective periods set forth therein, all
      in conformity with GAAP consistently applied during the periods
      involved except as otherwise noted therein, and subject, in the case
      of the unaudited interim financial statements, to the absence of notes
      and normal year-end adjustments that have not been and are not
      expected to be material in amount.  All of such Pfizer SEC Reports, as
      of their respective dates (and as of the date of any amendment to the
      respective Pfizer 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 Pfizer SEC Reports filed prior to
      the date hereof, since December 31, 1998, Pfizer 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 Pfizer 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, in the aggregate, would not
      reasonably be expected to have a Material Adverse Effect on Pfizer.

           (e)  Information Supplied.

           (i)  None of the information supplied or to be supplied by Pfizer
      for inclusion or incorporation by reference in (A) the Form S-4 (as
      defined in Section 5.1) 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

      threatened, against or affecting Pfizer or any Subsidiary of Pfizer
      which, in the aggregate, would reasonably be expected to have a
      Material Adverse Effect on Pfizer, nor are there any judgments,
      decrees, injunctions, rules or orders of any Governmental Entity or

      Subsidiaries are in compliance with the terms of the Pfizer Permits,
      except where the failures to so comply, in the aggregate, would not
      reasonably be expected to have a Material Adverse Effect on Pfizer.
      Except as disclosed in the Pfizer SEC Reports filed prior to the date
      of this Agreement, neither Pfizer nor any of its Subsidiaries is in
      violation of, and Pfizer and its Subsidiaries have not received any

           (n)  Accounting Matters.  To the knowledge of Pfizer, neither
 Pfizer nor any of its affiliates has taken or agreed to take any action,
 and no fact or circumstance is known to Pfizer, that would prevent Pfizer
 from accounting for the Merger as a "pooling-of-interests" under Opinion 16

 filed all Tax Returns required to have been filed (or extensions have been
 duly obtained) and has paid all Taxes required to have been paid by it,

 Regulation S-K of the SEC) or (ii) any non-competition agreements or any
 other agreements or arrangements that limit or otherwise restrict Pfizer or
 any of its Subsidiaries or any of their respective affiliates or any
 successor thereto, or that would, after the Effective Time, to the
 knowledge of Pfizer, limit or restrict Pfizer or any of its affiliates
 (including the Surviving Corporation) or any successor thereto, from
 engaging or competing in any line of business or in any geographic area,

 expected to have a Material Adverse Effect on Pfizer and its Subsidiaries

 after giving effect to the Merger.

 consummation of the Merger will not constitute an event under any Benefit
 Plan maintained by Pfizer that will or may result in any payment,
 acceleration, forgiveness of indebtedness, vesting, distribution, increase
 in compensation or benefits or obligation to fund benefits with respect to
 any Pfizer employee which, in the aggregate, have had, or would reasonably
 be expected to have, a Material Adverse Effect on Pfizer.

           3.2  REPRESENTATIONS AND WARRANTIES OF WARNER-LAMBERT.  Except as
 set forth in the Warner-Lambert Disclosure Schedule delivered by Warner-
 Lambert to Pfizer 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), Warner-
 Lambert represents and warrants to Pfizer as follows:

           (a)  Organization, Standing and Power; Subsidiaries.

           (i)  Each of Warner-Lambert and each of its Subsidiaries is 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 failures to be
      so organized, existing and in good standing or to have such power and
      authority, in the aggregate, would not reasonably be expected to have
      a Material Adverse Effect 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 failures so to qualify or to be in good standing in the
      aggregate would not reasonably be expected to have a Material Adverse
      Effect on Warner-Lambert.  The copies of the certificate of
      incorporation and bylaws of Warner-Lambert which were previously
      furnished or made available to Pfizer are true, complete and correct
      copies of such documents as in effect on the date of this Agreement.

           (ii) Exhibit 21 to Warner-Lambert's Annual Report on Form 10K for
      the year ended December 31, 1998 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 non-assessable and are, except as set
      forth in Exhibit 21, owned directly or indirectly by Warner-Lambert,
      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
      for restrictions imposed by applicable securities laws.  Except as set
      forth in the Warner-Lambert SEC Reports (as defined in Section 3.2(d))
      filed prior to the date hereof, 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, 1999, the authorized capital stock of

      other than issuances of shares (and accompanying Warner-Lambert
      Rights) pursuant to options or rights outstanding as of December 31,
      1999 under the Benefit Plans of Warner-Lambert.  All issued and
      outstanding shares of the capital stock of Warner-Lambert are duly
      authorized, validly issued, fully paid and non-assessable, and no
      class of capital stock is entitled to preemptive rights.  There were

      practice to purchase, in the aggregate, not more than 5,000 shares of

      Disclosure Schedule sets forth a complete and correct list, as of
      December 31, 1999, of the number of shares of Warner-Lambert Common
      Stock subject to Warner-Lambert Stock Options or other rights to
      purchase or receive Warner-Lambert Common Stock granted under the
      Warner-Lambert Benefit Plans or otherwise, the dates of grant and the
      exercise prices thereof.  Except in connection with pre-employment
      grants of Warner-Lambert Stock Options made in a manner consistent
      with past practice to purchase, in the aggregate, not more than 10,000
      shares of Warner-Lambert Common Stock, and except as set forth on
      Schedule 3.2(b)(i) of the Warner-Lambert Disclosure Schedule, no
      options or warrants or other rights to acquire capital stock from
      Warner-Lambert have been issued or granted since December 31, 1999 to
      the date of this Agreement.

           (ii) No bonds, debentures, notes or other indebtedness of Warner-
      Lambert having the right to vote on any matters on which stockholders
      may vote ("Warner-Lambert 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 Warner-Lambert or any of its
      Subsidiaries is a party or by which any of them is bound obligating
      Warner-Lambert 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 Warner-Lambert or any of its
      Subsidiaries or obligating Warner-Lambert 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 Warner-Lambert or any of its Subsidiaries
      to repurchase, redeem or otherwise acquire any shares of capital stock
      of Warner-Lambert or any of its Subsidiaries.


           (c)  Authority; No Conflicts.

           (i)  Warner-Lambert has all requisite corporate power and
      authority to enter into this Agreement and to consummate the
      transactions contemplated hereby, subject in the case of the
      consummation of the Merger to the adoption of this Agreement by the
      Required Warner-Lambert Vote (as defined in Section 3.2(g)).  The
      execution and delivery of this Agreement and the consummation of the
      transactions contemplated hereby have been duly authorized by all
      necessary corporate action on the part of Warner-Lambert, subject in
      the case of the consummation of the Merger to the adoption of this
      Agreement by the Required Warner-Lambert Vote.  This 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 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).

           (ii) The execution and delivery of this 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 will not, conflict with, or result in a Violation
      pursuant to:  (A) any provision of the certificate of incorporation or
      bylaws of Warner-Lambert or any material Subsidiary of Warner-Lambert
      or (B) except as, in the aggregate, would not reasonably be expected
      to have a Material Adverse Effect on Warner-Lambert or, 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 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 by Warner-Lambert 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, in
      the aggregate, would not reasonably be expected to have a Material
      Adverse Effect on Warner-Lambert.

           (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").  No Subsidiary of Warner-Lambert is
      required to file any form, report, registration statement or
      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

      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.  Each of the

      the consolidated financial position and consolidated results of
      operations and cash flows of Warner-Lambert and its consolidated
      Subsidiaries as of the respective dates or for the respective periods

      during the periods involved except as otherwise noted therein, and
      subject, in the case of the unaudited interim financial statements, to
      the absence of notes and normal and recurring year-end adjustments
      that have not been and 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, 1998, 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, in the
      aggregate, would not reasonably be expected to have a Material Adverse
      Effect on Warner-Lambert.

           (i)  None of the information supplied or to be supplied by
      Warner-Lambert for inclusion or incorporation by reference in (A) 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 Joint Proxy Statement/Prospectus will, on the date it is first
      mailed to Warner-Lambert stockholders or Pfizer stockholders or at the
      time of the Warner-Lambert Stockholders Meeting or the Pfizer
      Stockholders Meeting, 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 and the Joint Proxy Statement/Prospectus 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 3.2(e), no representation or warranty is made by Warner-
      Lambert with respect to statements made or incorporated by reference
      in the Form S-4 or the Joint Proxy Statement/Prospectus based on
      information supplied by Pfizer or Merger Sub for inclusion or
      incorporation by reference therein.

           (f)  Board Approval.  The Board of Directors of Warner-Lambert,
 by resolutions duly adopted by unanimous vote of those voting at a meeting

 the DGCL.  To the knowledge of Warner-Lambert, except for Section 203 of
 the DGCL (which has been rendered inapplicable), no state takeover statute
 is applicable to this Agreement, the Merger or the other transactions
 contemplated hereby or thereby.

           (g)  Vote Required.  The affirmative vote of the holders of a
 majority of the outstanding shares of Warner-Lambert Common Stock to adopt
 this Agreement and approve the Merger (the "Required Warner-Lambert Vote")

 capital stock necessary to adopt this Agreement and approve the Merger and
 the other transactions contemplated hereby.

      to the knowledge of Warner-Lambert, threatened, against or affecting
      Warner-Lambert or any Subsidiary of Warner-Lambert which, in the
      aggregate, would reasonably be expected to have a Material Adverse
      Effect on Warner-Lambert, nor are there any judgments, decrees,
      injunctions, rules or orders of any Governmental Entity or arbitrator
      outstanding against Warner-Lambert or any Subsidiary of Warner-Lambert
      which, in the aggregate, would reasonably be expected to have a
      Material Adverse Effect on Warner-Lambert.

           (ii) Except as disclosed in the Warner-Lambert SEC Reports filed

      to have a Material Adverse Effect on Warner-Lambert.

           (i)  Absence of Certain Changes or Events.  Except for

 contemplated hereby, except as disclosed in the Warner-Lambert SEC Reports
 filed prior to the date of this Agreement, except as permitted by

 Section 4.2.  Except as disclosed in the Warner-Lambert SEC Reports filed

 no facts, circumstances or conditions relating to, arising from, associated

 Subsidiaries or operations thereon would reasonably be expected to result
 in Environmental Liabilities, (iv) all real property owned and, to the

           (n)  Accounting Matters.  To the knowledge of Warner-Lambert,
 neither Warner-Lambert nor any of its affiliates has taken or agreed to
 take any action, and no fact or circumstance is known to Warner-Lambert,
 that would prevent Pfizer from accounting for the Merger as a "pooling-of-
 interests" under Opinion 16 of the Accounting Principles Board and
 applicable SEC rules and regulations.

 forth in the Warner-Lambert SEC Reports filed prior to the date of this
 Agreement, neither Warner-Lambert nor any of its Subsidiaries is a party to
 or bound by (i) any "material contracts" (as such term is defined in Item
 601(b)(10) of Regulation S-K of the SEC) or (ii) any non-competition
 agreements or any other agreements or arrangements that limit or otherwise
 restrict Warner-Lambert or any of its Subsidiaries or any of their
 respective affiliates or any successor thereto or that would, after the
 Effective Time, to the knowledge of Warner-Lambert, limit or restrict
 Pfizer or any of its affiliates (including the Surviving Corporation) or
 any successor thereto, from engaging or competing in any line of business
 or in any geographic area, which agreements or arrangements, in the
 aggregate, would reasonably be expected to have a Material Adverse Effect

 Lambert SEC Reports, there are no Benefit Plans maintained by Warner-
 Lambert covering only Warner-Lambert executive officers. Each Benefit Plan
 maintained by Warner-Lambert has been operated and administered in
 accordance with its terms and applicable law, except where failure to do so
 would not reasonably be expected to have a Material Adverse Effect on
 Warner-Lambert. The execution of this Agreement and the consummation of the
 Merger will not constitute an event under any Benefit Plan maintained by
 Warner-Lambert that will or may result in any payment, acceleration,

 compensation or benefits or obligation to fund benefits with respect to any
 Warner-Lambert Employee (US), Warner-Lambert Employee (Non-US) or Warner-
 Lambert Employee (Collective Bargaining Units) which, in the aggregate,

      having business dealings with them to the end that their ongoing
      businesses shall not be impaired in any material respect at the
      Effective Time; provided, however, that no action by Warner-Lambert or
      its Subsidiaries with respect to matters specifically addressed by any
      other provision of this Section 4.2 shall be deemed a breach of this
      Section 4.2(a)(i) unless such action would constitute a breach of one
      or more of such other provisions.

           (ii) Other than in connection with acquisitions permitted by
      Section 4.2(e), Warner-Lambert shall not, and shall not permit any of
      its Subsidiaries to, (A) enter into any licensing agreement, except
      for those licensing agreements set forth on Section 4.2(a)(ii) of the

      related to the Schick, Tetra, Capsugel or Adams divisions of Warner-
      Lambert; (B) enter into any new material line of business; (C) incur

      consumer healthcare businesses (except Schick, Tetra, and Capsugel),

      of inventories or for the furnishing of services by Warner-Lambert or
      any of its Subsidiaries which contract, agreement or other arrangement
      involves expenditures in excess of $10 million or which may give rise
      to commitments which may extend beyond twelve months from the date of
      such contract, agreement or arrangement, unless such contract,
      agreement or arrangement can be terminated by Warner-Lambert or its
      Subsidiary, as the case may be, by giving less than 60 days' notice
      and without incurring an obligation to pay any material premium or
      penalty or suffering any other material detriment.  As used herein, a
      "Permitted Capital Expenditure" is a capital expenditure which (i) is
      set forth on a Capital Expenditure Schedule to be delivered by Warner-

      million in the aggregate for all capital expenditures incurred

 reclassify any of its capital stock or issue or authorize or propose the
 issuance of any other securities in respect of, in lieu of or in
 substitution for, shares of its capital stock, except for any such

 wholly owned Subsidiary after consummation of such transaction, or
 (iii) repurchase, redeem or otherwise acquire any shares of its capital
 stock or any securities convertible into or exercisable for any shares of
 its capital stock except for the purchase from time to time by Warner-
 Lambert of Warner-Lambert Common Stock (and the associated Warner-Lambert

 not permit any of its Subsidiaries to, issue, deliver or sell, or authorize
 or propose the issuance, delivery or sale of, any shares of its capital

 options to acquire, any such shares or Warner-Lambert Voting Debt, or enter
 into any commitment, arrangement, undertaking or agreement with respect to
 any of the foregoing, other than (i) the issuance of Warner-Lambert Common
 Stock (and the associated Warner-Lambert Rights) upon the exercise of

 Schedule, (iv) pursuant to acquisitions set forth on the Warner-Lambert
 Disclosure Schedule or the financings therefor or (v) issuances in
 accordance with the Warner-Lambert Rights Agreement.

           (d)  Governing Documents.  Except to the extent required to
 comply with its obligations hereunder or with applicable law, Warner-
 Lambert shall not amend or propose to so amend its respective certificates
 of incorporation, bylaws or other governing documents.

           (e)  No Acquisitions.  Other than (i) acquisitions disclosed on
 the Warner-Lambert Disclosure Schedule and (ii) acquisitions for cash in
 existing or related lines of business of Warner-Lambert and its
 Subsidiaries, the fair market value of the total consideration (including

 $25 million for any individual acquisition, or $100 million in the
 aggregate for all such acquisitions, and none of which acquisitions

 difficult to obtain any approval or authorization required in connection
 with the Merger under Regulatory Laws,  Warner-Lambert shall not, and shall
 not permit any of its Subsidiaries to, acquire or agree to acquire by
 merging or consolidating with, or by purchasing a substantial equity
 interest in or a substantial portion of the assets of, or by any other

 the ordinary course of business), if the fair market value of the total
 consideration (including the value of the indebtedness acquired or assumed)
 therefor exceeds $25 million for any individual disposition, or $100
 million  in the aggregate for all such dispositions.

           (g)  Investments; Indebtedness.  Warner-Lambert shall not, and
 shall not permit any of its Subsidiaries to, other than in connection with
 actions permitted by Section 4.2(e) and except for any indebtedness
 incurred by Warner-Lambert or its Subsidiaries to finance or refinance
 amounts due pursuant to Article VII of the Agreement and Plan of Merger,
 dated as of November 3, 1999, among American Home Products Corporation,

 practice, in each case as such credit facilities, indentures and other
 arrangements and other existing indebtedness may be amended, extended,
 modified, refunded, renewed or refinanced after the date of this Agreement.

           (h)  Pooling; Tax-Free Qualification.  Warner-Lambert shall use
 its reasonable best efforts not to, and shall use its reasonable best
 efforts not to permit any of its Subsidiaries to, take any action
 (including any action otherwise permitted by this Section 4.2) that would

 Code.

           (i)  Compensation.  Other than as contemplated by Section 5.6 or
 by Sections 4.2(c) or 4.2(i) of the Warner-Lambert Disclosure Schedule,

 or any of its affiliates (including the Surviving Corporation) or any
 successor thereto, from engaging or competing in any line of business or in
 any geographic area which agreements or arrangements, individually or in
 the aggregate, would reasonably be expected to have a Material Adverse

                           ADDITIONAL AGREEMENTS

           5.1  PREPARATION OF PROXY STATEMENT; STOCKHOLDERS MEETINGS.
 (a)  As promptly as reasonably practicable following the date hereof,
 Pfizer and Warner-Lambert shall prepare and file with the SEC mutually
 acceptable proxy materials which shall constitute the Joint Proxy
 Statement/Prospectus (such proxy statement/prospectus, and any amendments
 or supplements thereto, the "Joint Proxy Statement/Prospectus") and Pfizer
 shall prepare and file a registration statement on Form S-4 with respect to
 the issuance of Pfizer Common Stock in the Merger (the "Form S-4").  The
 Joint Proxy Statement/Prospectus will be included in and will constitute a
 part of the Form S-4 as Pfizer's prospectus.  The Form S-4 and the Joint
 Proxy Statement/Prospectus shall comply as to form in all material respects
 with the applicable provisions of the Securities Act and the Exchange Act
 and the rules and regulations thereunder.  Each of Pfizer and Warner-
 Lambert shall use reasonable best efforts to have the Form S-4 declared
 effective by the SEC and to keep the Form S-4 effective as long as is
 necessary to consummate the Merger and the transactions contemplated
 thereby.  Pfizer and Warner-Lambert shall, as promptly as practicable after
 receipt thereof, provide the other party copies of any written comments and
 advise the other party of any oral comments, with respect to the Joint
 Proxy Statement/Prospectus received from the SEC.  Pfizer will provide
 Warner-Lambert with a reasonable opportunity to review and comment on any
 amendment or supplement to the Form S-4 prior to filing such with the SEC,
 and will provide Warner-Lambert with a copy of all such filings made with
 the SEC.  Notwithstanding any other provision herein to the contrary, no
 amendment or supplement (including by incorporation by reference) to the
 Joint Proxy Statement/Prospectus or the Form S-4 shall be made without the
 approval of both parties, which approval shall not be unreasonably withheld
 or delayed; provided, that with respect to documents filed by a party which
 are incorporated by reference in the Form S-4 or Joint Proxy
 Statement/Prospectus, this right of approval shall apply only with respect
 to information relating to the other party or its business, financial
 condition or results of operations; and provided, further, that Pfizer, in
 connection with a Change in the Pfizer Recommendation, and Warner-Lambert,
 in connection with a Change in the Warner-Lambert Recommendation, may amend
 or supplement the Joint Proxy Statement/Prospectus or Form S-4 (including
 by incorporation by reference) pursuant to a Qualifying Amendment (as
 defined below) to effect such a Change, and in such event, this right of
 approval shall apply only with respect to information relating to the other
 party or its business, financial condition or results of operations, and
 shall be subject to the right of each party to have its Board of Directors'
 deliberations and conclusions to be accurately described.  A "Qualifying
 Amendment" means an amendment or supplement to the Joint Proxy
 Statement/Prospectus or Form S-4 (including by incorporation by reference)
 to the extent it contains (i) a Change in the Pfizer Recommendation or a
 Change in the Warner-Lambert Recommendation (as the case may be), (ii) a
 statement of the reasons of the Board of Directors of Pfizer or Warner-
 Lambert (as the case may be) for making such Change in the Pfizer
 Recommendation or Change in the Warner-Lambert Recommendation (as the case
 may be) and (iii) additional information reasonably related to the
 foregoing.  Pfizer will use reasonable best efforts to cause the Joint
 Proxy Statements/Prospectus to be mailed to Pfizer stockholders, and
 Warner-Lambert will use reasonable best efforts to cause the Joint Proxy
 Statement/Prospectus to be mailed to Warner-Lambert's stockholders, in each
 case after the Form S-4 is declared effective under the Securities Act.
 Pfizer shall also take any action (other than qualifying to do business in
 any jurisdiction in which it is not now so qualified or to file a general
 consent to service of process) required to be taken under any applicable
 state securities laws in connection with the Share Issuance and Warner-
 Lambert shall furnish all information concerning Warner-Lambert and the
 holders of Warner-Lambert Common Stock as may be reasonably requested in
 connection with any such action.  Each party will advise the other party,
 promptly after it receives notice thereof, of the time when the Form S-4
 has become effective, the issuance of any stop order, the suspension of the
 qualification of the Pfizer Common Stock issuable in connection with the
 Merger for offering or sale in any jurisdiction, or any request by the SEC
 for amendment of the Joint Proxy Statement/Prospectus or the Form S-4.  If
 at any time prior to the Effective Time any information relating to Pfizer
 or Warner-Lambert, or any of their respective affiliates, officers or
 directors, should be discovered by Pfizer or Warner-Lambert which should be
 set forth in an amendment or supplement to any of the Form S-4 or the Joint
 Proxy Statement/Prospectus so that any of such documents would not include
 any misstatement of a material fact or omit to state any material fact
 necessary to make the statements therein, in light of the circumstances
 under which they were made, not misleading, the party which discovers such
 information shall promptly notify the other party hereto and, to the extent
 required by law, rules or regulations, an appropriate amendment or
 supplement describing such information shall be promptly filed with the SEC
 and disseminated to the stockholders of Pfizer and Warner-Lambert.

           (b)  Warner-Lambert shall duly take (subject to compliance with
 the provisions of Section 3.1(e) and Section 3.2(e) (provided that Warner-
 Lambert shall have used reasonable best efforts to ensure that such
 representations are true and correct)) all lawful action to call, give
 notice of, convene and hold a meeting of its stockholders on a date as soon
 as reasonably practicable (the "Warner-Lambert Stockholders Meeting") for
 the purpose of obtaining the Required Warner-Lambert Vote with respect to
 the transactions contemplated by this Agreement and shall take all lawful
 action to solicit the adoption of this Agreement by the Required Warner-
 Lambert Vote; and the Board of Directors of Warner-Lambert shall recommend
 adoption of this Agreement by the stockholders of Warner-Lambert to the
 effect as set forth in Section 3.2(f) (the "Warner-Lambert
 Recommendation"), and shall not withdraw, modify or qualify (or propose to
 withdraw, modify or qualify) (a "Change") in any manner adverse to Pfizer
 such recommendation or take any action or make any statement in connection
 with the Warner-Lambert Stockholders Meeting inconsistent with such
 recommendation (collectively, a "Change in the Warner-Lambert
 Recommendation"); provided the foregoing shall not prohibit accurate
 disclosure (and such disclosure shall not be deemed to be a Change in the
 Warner-Lambert Recommendation) of factual information regarding the
 business, financial condition or results of operations of Pfizer or Warner-
 Lambert or the fact that an Acquisition Proposal has been made, the
 identity of the party making such proposal or the material terms of such
 proposal (provided, that the Board of Directors of Warner-Lambert does not
 withdraw, modify or qualify (or propose to withdraw, modify or qualify) in
 any manner adverse to Pfizer its recommendation) in the Form S-4 or the
 Joint Proxy Statement/Prospectus or otherwise, to the extent such
 information, facts, identity or terms is required to be disclosed under
 applicable law; and, provided further, that the Board of Directors of
 Warner-Lambert may make a Change in the Warner-Lambert Recommendation
 (x) pursuant to Section 5.5 hereof or (y) prior to the Warner-Lambert
 Stockholders Meeting if (i) the Board of Directors of Warner-Lambert
 determines in good faith that a Material Adverse Effect has occurred with
 respect to Pfizer and (ii) the Board of Directors of Warner-Lambert
 determines in good faith that, by reason of its determination in clause (i)
 the failure to effect such Change in the Warner-Lambert Recommendation
 would create a substantial probability of violating the fiduciary duties of
 the Warner-Lambert Board of Directors under applicable law.
 Notwithstanding any Change in the Warner-Lambert Recommendation, this
 Agreement shall be submitted to the stockholders of Warner-Lambert at the
 Warner-Lambert Stockholders Meeting for the purpose of adopting the
 Agreement and approving the Merger; provided that this Agreement shall not
 be required to be submitted to the stockholders of Warner-Lambert at the
 Warner-Lambert Stockholders Meeting if this Agreement has been terminated
 pursuant to Section 7.1 hereof.

           (c)  Pfizer shall duly take (subject to compliance with the
 provisions of Section 3.2(e) and Section 3.1(e) (provided that Pfizer shall
 have used reasonable best efforts to ensure that such representation is
 true and correct)) all lawful action to call, give notice of, convene and
 hold a meeting of its stockholders on a date as soon as reasonably
 practicable (the "Pfizer Stockholders Meeting") for the purpose of
 obtaining the Pfizer Stockholder Approval and shall take all lawful action
 to solicit the approval of the Share Issuance and adoption of the Board
 Amendment and the Board of Directors of Pfizer shall recommend approval of
 the Share Issuance and adoption of the Board Amendment by the stockholders
 of Pfizer to the effect as set forth in Section 3.1(f) (the "Pfizer
 Recommendation"), and shall not Change in any manner adverse to Warner-
 Lambert such recommendation or take any action or make any statement in
 connection with the Pfizer Stockholders Meeting inconsistent with such
 recommendation (collectively, a "Change in the Pfizer Recommendation");
 provided the foregoing shall not prohibit accurate disclosure (and such
 disclosure shall not be deemed to be a Change in the Pfizer Recommendation)
 of factual information regarding the business, financial condition or
 operations of Pfizer or Warner-Lambert or the fact that an Acquisition
 Proposal has been made, the identity of the party making such proposal or
 the material terms of such proposal (provided, that the Board of Directors
 of Pfizer does not withdraw, modify or qualify (or propose to withdraw,
 modify or qualify) in any manner adverse to Warner-Lambert its
 recommendation) in the Form S-4 or the Joint Proxy Statement/Prospectus or
 otherwise, to the extent such information, facts, identity or terms is
 required to be disclosed under applicable law; and, provided, further, that
 the Board of Directors of Pfizer may make a Change in the Pfizer
 Recommendation (x) pursuant to Section 5.5 hereof or (y) prior to the
 Pfizer Stockholders Meeting if (i) the Board of Directors of Pfizer
 determines in good faith that a Material Adverse Effect has occurred with
 respect to Warner-Lambert and (ii) the Board of Directors of Pfizer
 determines in good faith that, by reason of its determination in clause (i)
 the failure to effect such Change in the Pfizer Recommendation would create
 a substantial probability of violating the fiduciary duties of the Pfizer
 Board of Directors under applicable law.  Notwithstanding any Change in the
 Pfizer Recommendation, a proposal to approve the Share Issuance and the
 Board Amendment shall be submitted to the stockholders of Pfizer at the
 Pfizer Stockholders Meeting for the purpose of obtaining the Pfizer
 Stockholder Approval; provided that this Agreement shall not be required to
 be submitted to the stockholders of Pfizer at the Pfizer Stockholders
 Meeting if this Agreement has been terminated pursuant to Section 7.1
 hereof.

           (d)  For purposes of this Agreement, a Change in the Warner-
 Lambert Recommendation shall be deemed to include, without limitation, a
 recommendation by the Warner-Lambert Board of Directors of a third party
 Acquisition Proposal with respect to Warner-Lambert and a Change in the
 Pfizer Recommendation shall be deemed to include, without limitation, a
 recommendation by the Pfizer Board of Directors of a third party
 Acquisition Proposal with respect to Pfizer.

           5.2  PFIZER BOARD OF DIRECTORS; EXECUTIVE OFFICERS; HEADQUARTERS;
 WARNER-LAMBERT NAME.  (a)  At or prior to the Effective Time, Pfizer will
 use its reasonable best efforts to (i) reconstitute the board of directors
 of Pfizer in accordance with Section 1.5(b), Section 1.6(b) and

 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 all its
 properties, books, contracts, commitments, records, officers and employees
 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,

 (b) all other information concerning it and its business, properties and
 personnel as such other party may reasonably request (including
 consultation on a regular basis with respect to litigation matters);
 provided, however, that either party may restrict the foregoing access to
 the extent that (i) any law, treaty, rule or regulation of any Governmental
 Entity applicable to such party requires such party or its Subsidiaries to
 restrict or prohibit access to any such properties or information or
 (ii) the information is subject to confidentiality obligations to a third
 party. Any such information obtained pursuant to this Section 5.3
 ("Confidential Information") will be used solely for the purpose of

 information and directs them to treat such information confidentially and
 to use such information for no purpose other than as specifically permitted
 by the Agreement and (y) if the party is legally required to make such
 disclosure as a result of a court order, subpoena or similar legal duress,
 provided that prior to such disclosure, the disclosing party gives to the
 other party prompt written notice of its receipt of such order or subpoena
 or similar document so that the other party has a reasonable opportunity
 prior to disclosure to obtain a protective order (if disclosure of
 Confidential Information is so required, the disclosing party shall
 disclose only that portion of such information that is so required and
 shall assist the other party in obtaining protective orders or undertakings
 that confidential treatment will be accorded to any such information
 furnished).  In the event of termination of this Agreement, each party will
 promptly return to the other party all Confidential Information in its
 possession (including all written materials prepared or supplied by or on
 its behalf containing or reflecting any Confidential Information) and will
 not retain any copies, extracts or other reproductions in whole or in part

 establish a mechanism reasonably acceptable to both parties by which Pfizer
 will be permitted, prior to the Effective Time and subject to applicable
 law, to communicate directly with Warner-Lambert employees regarding

 Lambert 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 is not conditioned on the Closing or, in the
 aggregate, would reasonably be expected to have a Material Adverse Effect
 on Pfizer and its Subsidiaries (including the Surviving Corporation and its
 Subsidiaries), taken together, after giving effect to the Merger.

           (b)  Each of Pfizer and Warner-Lambert shall, in connection with
 the efforts referenced in Section 5.4(a) 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"), the Federal Trade Commission (the "FTC")
 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, the FTC
 or any such other Governmental Entity or, in connection with any proceeding
 by a private party, with any other Person, and to the extent appropriate or
 permitted by the DOJ, the FTC 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, Council
 Regulation No. 4064/89 of the European Community, as amended (the "EC
 Merger Regulation") 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 (i) foreign investment or (ii) 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 Pfizer and
 Warner-Lambert shall cooperate in all respects with each other and use its
 respective reasonable best efforts, including without limitation, selling,
 holding separate or otherwise disposing of or conducting their business in
 a specified manner, or agreeing to sell, hold separate or otherwise dispose
 of or conduct their business in a specified manner or permitting the sale,
 holding separate or other disposition of, any assets of Pfizer, Warner-
 Lambert or their respective Subsidiaries or the conducting of their
 business in a specified manner, in order 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; provided that the foregoing is subject
 in all respects to the last sentence of Section 5.4(a).

           (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 transactions contemplated hereby as violative of any Regulatory Law,
 each of Pfizer and Warner-Lambert 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.

           5.5  ACQUISITION PROPOSALS.  Without limitation on any of such
 party's other obligations under this Agreement (including under Article IV
 hereof), each of Pfizer and Warner-Lambert 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 use its reasonable best efforts to
 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, solicit,
 encourage or knowingly facilitate (including by way of furnishing
 information) any inquiries or the making of any proposal or offer with
 respect to a merger, reorganization, share exchange, consolidation,
 business combination, recapitalization, liquidation, dissolution or similar
 transaction involving it, or any purchase or sale of the consolidated
 assets (including without limitation stock of Subsidiaries) of such party
 and its Subsidiaries, taken as a whole, having an aggregate value equal to
 10% or more of the market capitalization of such party, or any purchase or
 sale of, or tender or exchange offer for, 10% or more of the equity
 securities of such party (any such proposal or offer (other than a proposal
 or offer made by the other party or an affiliate thereof) being hereinafter
 referred to as an "Acquisition Proposal").  Each of Pfizer and Warner-
 Lambert 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 use its reasonable best efforts to 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,
 or knowingly facilitate any effort or attempt to make or implement an
 Acquisition Proposal or accept an Acquisition Proposal.  Notwithstanding
 anything in this Agreement to the contrary, each of Pfizer and Warner-
 Lambert or its respective Board of Directors shall be permitted to (A) to
 the extent applicable, comply with Rule 14d-9 and Rule 14e-2 promulgated
 under the Exchange Act with regard to an Acquisition Proposal, (B) effect a
 Change in the Pfizer or Warner-Lambert Recommendation, as the case may be,
 or (C) 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
 any such case as is referred to in clause (B) or (C), (i) its Stockholders
 Meeting shall not have occurred, (ii) (x) in the case of clause (B) above
 such change is permitted by clause (y) of the second proviso of the first
 sentence of Section 5.1(b) or Section 5.1(c), as the case may be, or it has
 received an unsolicited bona fide written Acquisition Proposal from a third
 party and its Board of Directors concludes in good faith that such
 Acquisition Proposal constitutes a Superior Proposal (as defined in Section
 8.11)  and (y) in the case of clause (C) above, its Board of Directors
 concludes in good faith that there is a reasonable likelihood that such
 Acquisition Proposal could result in a Superior Proposal, (iii) prior to
 providing any information or data to any Person in connection with an
 Acquisition Proposal by any such Person, its Board of Directors receives
 from such Person an executed confidentiality agreement containing terms at
 least as stringent as those contained in Section 5.3 and (iv) prior to
 providing any information or data to any Person or entering into
 discussions or negotiations with any Person, such party notifies the other
 party 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 inquiries, proposals or offers.  Each of Pfizer
 and Warner-Lambert agrees that it will promptly keep the other party
 informed of the status and terms of any such proposals or offers and the
 status and terms of any such discussions or negotiations.  Each of Pfizer
 and Warner-Lambert agrees that it will, and will cause its officers,
 directors and representatives to, immediately cease and cause to be
 terminated any activities, discussions or negotiations existing as of the
 date of this Agreement with any parties conducted heretofore with respect
 to any Acquisition Proposal.  Each of Pfizer and Warner-Lambert agrees that
 it will use reasonable best efforts to promptly inform its directors,
 officers, key employees, agents and representatives of the obligations
 undertaken in this Section 5.5.  Nothing in this Section 5.5 shall
 (x) permit Pfizer or Warner-Lambert to terminate this Agreement (except as
 specifically provided in Article VII hereof) or (y) affect any other
 obligation of Pfizer or Warner-Lambert under this Agreement.

           5.6  EMPLOYEE BENEFITS MATTERS.  (a)  Warner-Lambert Employees
 (US).  Following the Effective Time, Pfizer shall comply with the terms of,
 or cause the Surviving Corporation to comply with the terms of, all Warner-
 Lambert Benefit Plans and related funding arrangements in accordance with
 their respective terms.  Nothing herein shall require Pfizer to continue
 any particular Benefit Plan or prevent the amendment or termination
 thereof; provided, however, that Pfizer shall not take any action (by way
 of amendment, termination or otherwise) which is in violation of the terms
 of any Benefit Plan or applicable law.  Subject to the first two sentences
 of this Section 5.6(a), from and after the Effective Time until the first
 anniversary of the Effective Time, Pfizer shall provide compensation and
 employee benefits under Benefit Plans (as defined in Section 8.11) to the
 employees and former employees of Warner-Lambert and its Subsidiaries who
 are employed in the United States (including Puerto Rico) and employees
 designated by Warner-Lambert as "foreign service colleagues" (the "Warner-
 Lambert Employees (US)") that are substantially comparable in the aggregate
 to those provided to such persons pursuant to the Warner-Lambert Benefit
 Plans in effect immediately prior to the date hereof.  The term "Warner-
 Lambert Employees (US)" shall not include Warner-Lambert Employees (Non-US)
 or Warner-Lambert Employees (Collective Bargaining Units).  With respect to
 any Benefit Plans in which any Warner-Lambert Employees (US) first become
 eligible to participate, on or after the Effective Time, Pfizer shall:
 (A) waive all pre-existing conditions exclusions and waiting periods with
 respect to participation and coverage requirements applicable to Warner-
 Lambert Employees (US) under any Pfizer plans in which such employees may
 be eligible to participate after the Effective Time, except to the extent
 that such pre-existing conditions exclusions or waiting periods apply to
 changes made by the employee under the terms of the Pfizer plans on the
 same basis as would apply to a Pfizer employee making a similar change;
 (B) provide each Warner-Lambert Employee (US) with credit for any co-
 payments and deductibles paid prior to the Effective Time (to the same
 extent such credit was given under the analogous Benefit Plan prior to the
 Effective Time) in satisfying any applicable deductible or out-of-pocket
 requirements under any Pfizer plans in which such employees may be eligible
 to participate after the Effective Time; and (C) recognize all service of
 the Warner-Lambert Employees (US) with Warner-Lambert and its Subsidiaries
 for all purposes (including, without limitation, purposes of eligibility to
 participate, vesting credit, entitlement to benefits, and benefit accrual)
 in any Pfizer 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 Pfizer plan; provided, that the foregoing shall not
 apply to the extent it would result in duplication of benefits under
 multiple plans or would result in benefit accruals under multiple defined
 benefit pension plans with respect to the same period of service without
 offset for benefits accrued under a predecessor defined benefit pension
 plan.  Warner-Lambert's board of directors will not declare an "other
 circumstance" to have occurred within the meaning of Section 4.2(y) of
 Warner-Lambert's Enhanced Severance Plan.  During the period from the date
 of this Agreement and continuing until the Effective Time, Warner-Lambert
 agrees as to itself and its Subsidiaries that neither Warner-Lambert nor
 any of its Subsidiaries shall take or cause to be taken any action that
 would constitute an "Activation Event" (as defined in Section 4.2 of
 Warner-Lambert's Enhanced Severance Plan), other than in the ordinary
 course of business.

           (b)  Warner-Lambert Employees (Non-US).  From and after the
 Effective Time until the first anniversary of the Effective Time, Pfizer
 shall provide compensation and employee benefits to the employees and
 former employees of Warner-Lambert and its Subsidiaries who are employed
 outside the United States (other than any such employee who is a Warner-
 Lambert Employee (US)) ("Warner-Lambert Employees (Non-US)") that are
 substantially comparable in the aggregate to those provided to such persons
 immediately prior to the date hereof, subject to: such modifications as are
 necessary to comply with applicable laws of the foreign countries and their
 political subdivisions; and applicable labor agreements.  Nothing herein
 shall serve to extend any benefits under any plans maintained for the
 benefit of Warner-Lambert Employees (US) to any person who is not a Warner-
 Lambert Employee (US).  The term Warner-Lambert Employees (Non-US) shall
 not include Warner-Lambert Employees (US) or Warner-Lambert Employees
 (Collective Bargaining Units).

           (c)  Warner-Lambert Employees (Collective Bargaining Units).  The
 terms and conditions of employment of Warner-Lambert employees and former
 employees who are covered by the Agreement between Parke-Davis Warner-
 Lambert Company and the International Union of Operating Engineers, Local
 547-A, B, C, E, H uAFL-CIO, dated April 1, 1998 or the Agreement between
 Warner-Lambert Company and the Paper, Allied-Industrial, Chemical and
 Energy Workers International Union, AFL- CIO and its Local Union No. 2-670,
 dated May 1, 1999 or any other collective bargaining agreements between
 Warner-Lambert or its Subsidiaries and any other collective bargaining unit
 ("Warner-Lambert Employees (Collective Bargaining Units)"), are contained,
 and shall be as explicitly set forth, in such agreements.  The term Warner-
 Lambert Employees (Collective Bargaining Units) shall not include Warner-
 Lambert Employees (US) or Warner-Lambert Employees (Non-US).

           5.7  FEES AND EXPENSES.   Subject to Section 5.15 and Section
  7.2, whether or not the Merger is consummated, all Expenses incurred in
 connection with this Agreement and the transactions contemplated hereby
 shall be paid by the party incurring such Expenses, except (a) if the
 Merger is consummated, the Surviving Corporation or its relevant Subsidiary
 shall pay, or cause to be paid, any and all property or transfer taxes
 imposed on Warner-Lambert or its Subsidiaries and (b) Expenses incurred in
 connection with the filing, printing and mailing of the Joint Proxy
 Statement/Prospectus, which shall be paid by Pfizer.  As used in this
 Agreement, "Expenses" 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 contemplated hereby,
 including the preparation, printing, filing and mailing of the Joint Proxy
 Statement/Prospectus and the solicitation of stockholder approvals and all
 other matters related to the transactions contemplated hereby.

           5.8  DIRECTORS' AND OFFICERS' INDEMNIFICATION AND INSURANCE.  The
 Surviving Corporation shall, and Pfizer 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
 Warner-Lambert and its Subsidiaries (in all of their capacities) (a) to the
 same extent such persons are indemnified or have the right to advancement
 of expenses as of the date of this Agreement by Warner-Lambert pursuant to
 Warner-Lambert's certificate of incorporation, bylaws and indemnification
 agreements, if any, in existence on the date hereof with any directors,
 officers and employees of Warner-Lambert and its Subsidiaries and
 (b) without limitation to clause (a), to the fullest extent permitted by
 law, in each case 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), (ii) include and cause to be maintained
 in effect in the Surviving Corporation's (or any successor's) certificate
 of incorporation and bylaws for a period of six years after the Effective
 Time, the current provisions regarding elimination of liability of
 directors, indemnification of officers, directors and employees and
 advancement of expenses contained in the certificate of incorporation and
 bylaws of Warner-Lambert and (iii) 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 Warner-Lambert (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.  The obligations
 of the Surviving Corporation under this Section 5.8 shall not be terminated
 or modified in such a manner as to adversely affect any indemnitee to whom
 this Section 5.8 applies without the consent of such affected indemnitee
 (it being expressly agreed that the indemnitees to whom this Section 5.8
 applies shall be third party beneficiaries of this Section 5.8).

           5.9  PUBLIC ANNOUNCEMENTS.  Pfizer and Warner-Lambert shall use
 reasonable best efforts to develop a joint communications plan and each
 party shall use reasonable best efforts (i) to ensure that all press
 releases and other public statements with respect to 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, to consult with each other before issuing any press
 release or, to the extent practical, otherwise making any public statement
 with respect to this Agreement or the transactions contemplated hereby.  In
 addition to the foregoing, except to the extent disclosed in or consistent
 with the Joint Proxy Statement/Prospectus in accordance with the provisions
 of Section 5.1, neither Pfizer nor Warner-Lambert 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.

 efforts to cause to be delivered to Warner-Lambert two letters from
 Pfizer's independent public accountants, one dated approximately the date
 on which the Form S-4 shall become effective and one dated the Closing
 Date, each addressed to Pfizer and Warner-Lambert, in form reasonably
 satisfactory to Warner-Lambert and customary in scope for comfort letters
 delivered by independent public accountants in connection with registration
 statements similar to the Form S-4.  Pfizer shall use reasonable best
 efforts to cause to be delivered to Warner-Lambert a copy of a letter from
 Pfizer's independent accountants, dated approximately the date the Form S-4
 is declared effective and as of the Closing Date, stating that accounting
 for the Merger as a pooling-of-interests under Opinion 16 of the Accounting
 Principles Board and applicable SEC rules and regulations is appropriate if

           (b)  Warner-Lambert shall use reasonable best efforts to cause to
 be delivered to Pfizer two letters from Warner-Lambert's independent public
 accountants, one dated approximately the date on which the Form S-4 shall
 become effective and one dated the Closing Date, each addressed to Warner-
 Lambert and Pfizer, in form reasonably satisfactory to Pfizer and customary
 in scope for comfort letters delivered by independent public accountants in
 connection with registration statements similar to the Form S-4.  Warner-
 Lambert shall use reasonable best efforts to cause to be delivered to
 Pfizer a copy of a letter from Warner-Lambert's independent public
 accountants, addressed to Warner-Lambert, dated approximately the date the
 Form S-4 is declared effective and as of the Closing Date, stating that
 they concur with Warner-Lambert's conclusion that, as of the date of their
 report, no conditions exist that would preclude Warner-Lambert's ability to
 be a party in a business combination to be accounted for as a pooling-of-
 interests.

           (c)  Following execution of this Agreement, each of Pfizer and
 Warner-Lambert shall use reasonable best efforts to cause the transactions
 contemplated by this Agreement, including the Merger, to be accounted for

 Board and applicable SEC rules and regulations, and such accounting
 treatment to be accepted by the SEC.

           5.11 LISTING OF SHARES OF PFIZER COMMON STOCK.  Pfizer shall use
 its reasonable best efforts to cause the shares of Pfizer Common Stock to

 reserved for issuance upon exercise of the Warner-Lambert Stock Options to
 be approved for listing on the NYSE, subject to official notice of
 issuance, prior to the Closing Date.

           5.12 DIVIDENDS.  After the date of this Agreement, each of Pfizer
 and Warner-Lambert shall coordinate with the other the payment of dividends
 with respect to the Pfizer Common Stock and Warner-Lambert Common Stock and

 one dividend, for any single calendar quarter with respect to their shares
 of Pfizer Common Stock and/or Warner-Lambert Common Stock or any shares of
 Pfizer Common Stock that any such holder receives in exchange for such

 under the Securities Act or for purposes of qualifying the Merger for
 pooling-of-interests accounting treatment under Opinion 16 of the
 Accounting Principles Board and applicable SEC rules and regulations, and
 such list shall be updated as necessary to reflect changes from the date
 thereof.  Warner-Lambert shall use reasonable best efforts to cause each
 person identified on such list to deliver to Pfizer not less than 30 days
 prior to the Effective Time, a written agreement substantially in the form
 attached as Exhibit 5.13 hereto (an "Affiliate Agreement").  Not less than

 consents, approvals and actions of, filings with and notices to any
 Governmental Entity required of Pfizer, Warner-Lambert or any of their
 Subsidiaries to consummate the Merger, the Share Issuance and the other

                         TERMINATION AND AMENDMENT

           7.1  TERMINATION.  This Agreement may be terminated at any time
 prior to the Effective Time, by action taken or authorized by the Board of
 Directors of the terminating party or parties, and except as provided
 below, whether before or after approval of the matters presented in
 connection with the Merger by the stockholders of Warner-Lambert or Pfizer:

           (a)  By mutual written consent of Pfizer and Warner-Lambert;

           (b)  By either Warner-Lambert or Pfizer, if the Effective Time
 shall not have occurred on or before December 31, 2000 (the "Termination
 Date"); provided, however, that the right to terminate this Agreement under
 this Section 7.1(b) shall not be available to any party whose failure to
 fulfill any obligation under this Agreement (including without limitation
 such party's obligations set forth in Section 5.4) has been the cause of,
 or resulted in, the failure of the Effective Time to occur on or before the
 Termination Date and provided further that if on the Termination Date the
 conditions to Closing set forth in Sections 6.1(c) or 6.1(d) shall not have
 been fulfilled but all other conditions to Closing shall be fulfilled or
 shall be capable of being fulfilled then the Termination Date shall be
 automatically extended to March 31, 2001;

           (c)  By either Warner-Lambert or Pfizer, if any Governmental
 Entity (i) shall have issued an order, decree or ruling or taken any other
 action (which the parties shall have used their reasonable best efforts to
 resist, resolve or lift, as applicable, in accordance with Section 5.4)
 permanently restraining, enjoining or otherwise prohibiting the
 transactions contemplated by this Agreement, and such order, decree, ruling
 or other action shall have become final and nonappealable or (ii) shall
 have failed to issue an order, decree or ruling or to take any other action
 (which order, decree, ruling or other action the parties shall have used
 their reasonable best efforts to obtain, in accordance with Section 5.4),
 in the case of each of (i) and (ii) which is necessary to fulfill the
 conditions set forth in Sections 6.1(c) and (d), as applicable, and such
 denial of a request to issue such order, decree, ruling or take such other
 action shall have become final and nonappealable; provided, however, that
 the right to terminate this Agreement under this Section 7.1(c) shall not
 be available to any party whose failure to comply with Section 5.4 has been
 the cause of such action or inaction;

           (d)  By either Warner-Lambert or Pfizer, if the approvals of the
 stockholders of either Pfizer or Warner-Lambert contemplated by this
 Agreement (other than the Board Amendment) shall not have been obtained by
 reason of the failure to obtain the required vote at a duly held meeting of
 stockholders or of any adjournment thereof at which the vote was taken;

           (e)  By Pfizer, if Warner-Lambert shall have failed to make the
 Warner-Lambert Recommendation or effected a Change in the Warner-Lambert

 obligations under this Agreement by reason of a failure to call the Warner-
 Lambert Stockholders Meeting in accordance with Section 5.1(b);

           (f)  By Warner-Lambert, if Pfizer shall have failed to make the
 Pfizer Recommendation or effected a Change in the Pfizer Recommendation (or

 hereof, or shall have materially breached its obligations under this
 Agreement by reason of a failure to call the Pfizer Stockholders Meeting in
 accordance with Section 5.1(c);

           (g)  By either Pfizer or Warner-Lambert, if there shall have been
 a breach by the other of any of its representations, warranties, covenants
 or obligations contained in this Agreement, which breach would result in
 the failure to satisfy the conditions set forth in Section 6.2(a) or
 Section 6.2(b)  (in the case of a breach by Warner-Lambert) or Section
 6.3(a) or Section 6.3(b)  (in the case of a breach by Pfizer), and in any
 such case such breach shall be incapable of being cured or, if capable of
 being cured, shall not have been cured within 30 days after written notice
 thereof shall have been received by the party alleged to be in breach;

           (h)  [Intentionally omitted]

           (i)   By Warner-Lambert, if the Board of Directors of Warner-
 Lambert authorizes Warner-Lambert to enter into a written agreement
 concerning a transaction that the Board of Directors of Warner-Lambert has
 determined is a Superior Proposal; provided, that Warner-Lambert shall not
 terminate this Agreement pursuant to this Section 7.1(i) and enter into a
 definitive agreement for a Business Combination until the expiration of
 five (5) Business Days following Pfizer's receipt of written notice
 advising Pfizer that Warner-Lambert has received a Superior Proposal
 specifying the material terms and conditions of such Superior Proposal (and
 including a copy thereof with all accompanying documentation, if in
 writing), identifying the person making such Superior Proposal and stating
 whether Warner-Lambert intends to enter into a definitive agreement for a
 Business Combination.  After providing such notice, Warner-Lambert shall
 provide a reasonable opportunity to Pfizer during such period to make such
 adjustments in the terms and conditions of this Agreement as would enable
 Warner-Lambert to proceed with the Merger on such adjusted terms;

           (j)  By Pfizer, if the Board of Directors of Pfizer authorizes
 Pfizer to enter into a written agreement concerning a transaction that the
 Board of Directors of Pfizer has determined is a Superior Proposal;
 provided, that Pfizer shall not terminate this Agreement pursuant to this
 Section 7.1(j) and enter into a definitive agreement for a Business
 Combination until the expiration of five (5) Business Days following
 Warner-Lambert's receipt of written notice advising Warner-Lambert that
 Pfizer has received a Superior Proposal specifying the material terms and
 conditions of such Superior Proposal (and including a copy thereof with all
 accompanying documentation, if in writing), identifying the person making
 such Superior Proposal and stating whether Pfizer intends to enter into a
 definitive agreement for a Business Combination.  After providing such
 notice, Pfizer shall provide a reasonable opportunity to Warner-Lambert
 during such period to make such adjustments in the terms and conditions of
 this Agreement as would enable Pfizer to proceed with the Merger on such
 adjusted terms; or

           (k)  By either Pfizer or Warner-Lambert, if the Joint Proxy
 Statement/Prospectus (reflecting pooling of interests accounting treatment)
 had not been mailed to stockholders of Warner-Lambert and Pfizer on or
 prior to September 30, 2000, provided that this right of termination is not
 available to any party which has not used its reasonable best efforts to
 cause such Joint Proxy Statement/Prospectus to be so mailed.

           7.2  EFFECT OF TERMINATION.  (a)  In the event of termination of
 this Agreement by either Warner-Lambert or Pfizer as provided in
 Section 7.1, this Agreement shall forthwith become void and there shall be
 no liability or obligation on the part of Pfizer or Warner-Lambert or their
 respective officers or directors except with respect to Section 3.1(l),
 Section 3.2(l), Section 5.3, Section 5.7, Section 5.15, this Section 7.2
 and Article VIII, which provisions shall survive such termination, and
 except that, notwithstanding anything to the contrary contained in this
 Agreement, neither Pfizer nor Warner-Lambert shall be relieved or released
 from any liabilities or damages arising out of its willful material breach
 of this Agreement.

           (b)  In the event that this Agreement is terminated pursuant to
 Section 7.1 herein under circumstances which constitute either a Pfizer
 Termination Event or a Neutral Termination Event, then Pfizer shall pay to
 Warner-Lambert not later than three Business Days after the date of such
 termination an amount in cash equal to $1.8 billion (the "Pfizer
 Termination Fee").  In the event this Agreement is terminated pursuant to
 Section 7.1  herein (a) under circumstances which constitute a Warner-
 Lambert Termination Event under clauses (ii) or (iv) of the definition
 thereof (including the proviso to Section 5.15(e)) and (b) at the time of
 the event giving rise to the right of termination there shall be pending a
 Superior Proposal with respect to Warner-Lambert, then Warner-Lambert shall
 pay to Pfizer not later than three Business Days after the date of such
 termination an amount in cash equal to $500 million (the "Warner-Lambert
 Termination Fee").

           (c)  If Warner-Lambert receives the Pfizer Termination Fee
 pursuant to Section 7.2(b) and within twelve months following termination
 of this Agreement Warner-Lambert enters into a definitive agreement with a
 third party with respect to a Business Combination, then Warner-Lambert
 shall repay to Pfizer, without any interest thereon, not later than three
 Business Days after the date of entering into such definitive agreement,
 the Pfizer Termination Fee, provided that Warner-Lambert shall not be
 obligated to repay to Pfizer the Pfizer Termination Fee if (A) Pfizer
 terminates this Agreement pursuant to Section 7.1(j) herein, (B) (I)
 Warner-Lambert terminates this Agreement pursuant to Section 7.1(f) herein
 and (II) Pfizer's Board of Directors shall have, prior to termination,
 effected a Change in the Pfizer Recommendation following the making of a
 proposal for a Business Combination with respect to Pfizer that continued
 to be pending at the time of the event giving rise to the right of
 termination, (C) (I) either Warner-Lambert or Pfizer terminates this
 Agreement pursuant to Section 7.1(d) herein (provided the basis for such
 termination is the failure of Pfizer's stockholders to approve the Share
 Issuance) and (II) a proposal for a Business Combination with respect to
 Pfizer had been made prior to such vote and continued to be outstanding at
 the time of the event giving rise to the right of termination, or (D) at
 the time of termination of this Agreement, Pfizer had breached its
 representations, warranties, covenants or obligations under this Agreement
 which breach entitles Warner-Lambert to terminate this Agreement pursuant
 to Section 7.1(g).  If Pfizer receives the Warner-Lambert Termination Fee
 pursuant to Section 7.2(b) and within twelve months following termination
 of this Agreement Pfizer enters into a definitive agreement with a third
 party with respect to a Business Combination, then Pfizer shall repay to
 Warner-Lambert, without any interest thereon, not later than three Business
 Days after the date of entering into such definitive agreement, the Warner-
 Lambert Termination Fee, provided that Pfizer shall not be obligated to
 repay to Warner-Lambert the Warner-Lambert Termination Fee if (A) Warner-
 Lambert terminates this Agreement pursuant to Section 7.1(i) herein, (B)
 (I) Pfizer terminates this Agreement pursuant to Section 7.1(e) herein and
 (II) Warner-Lambert's Board of Directors shall have, prior to termination,
 effected a Change in the Warner-Lambert Recommendation following the making

 that continued to be pending at the time of the event giving rise to the
 right of termination, (C) (I) either Warner-Lambert or Pfizer terminates
 this Agreement pursuant to Section 7.1(d) herein (provided the basis for
 such termination is the failure of Warner-Lambert's stockholders adopt this
 Agreement and approve the Merger) and (II) a proposal for a Business
 Combination with respect to Warner-Lambert had been made prior to such vote
 and continued to be outstanding at the time of the event giving rise to the
 right of termination, or (D) at the time of termination of this Agreement,
 Warner-Lambert had breached its representations, warranties, covenants or
 obligations under this Agreement which breach entitles Pfizer to terminate
 this Agreement pursuant to Section 7.1(g).

           (d)  For the purposes of this Section 7.2,  "Business
 Combination" means with respect to Warner-Lambert or Pfizer, as the case
 may be, (i) a merger, reorganization, consolidation, share exchange,
 business combination, recapitalization, liquidation, dissolution or similar
 transaction involving such party as a result of which either (A) such
 party's stockholders prior to such transaction (by virtue of their
 ownership of such party's shares) in the aggregate cease to own at least
 60% of the voting securities of the entity surviving or resulting from such
 transaction (or the ultimate parent entity thereof) or, regardless of the
 percentage of voting securities held by such stockholders, if any Person
 shall beneficially own, directly or indirectly, at least 40% of the voting
 securities of such ultimate parent entity, or (B) the individuals
 comprising the board of directors of such party prior to such transaction
 do not constitute a majority of the board of directors of such ultimate
 parent entity, (ii) a sale, lease, exchange, transfer or other disposition
 of at least 40% of the assets of such party and its Subsidiaries, taken as

 ownership of 40% or more of the common stock of such party whether by
 merger, consolidation, share exchange, business combination, tender or
 exchange offer or otherwise (other than a merger, reorganization,
 consolidation, share exchange, business combination, recapitalization,
 liquidation, dissolution or similar transaction upon the consummation of
 which such party's stockholders would in the aggregate beneficially own
 greater than 60% of the voting securities of such Person).

           (e)  All payments under this Section 7.2 and Section 5.15 shall
 be made by wire transfer of immediately available funds to an account
 designated by the party entitled to receive such payment.

           7.3  AMENDMENT.  This Agreement may be amended by the parties
 hereto, by action taken or authorized by their respective Boards of
 Directors, at any time before or after approval of the matters presented in
 connection with the Merger by the stockholders of Warner-Lambert and
 Pfizer, 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.

           7.4  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.

 parties and their respective successors and assigns.
