Item 5.           Other Events.

              Agouron  Pharmaceuticals,   Inc.  ("Agouron"  or  the  "Company"),
Warner-Lambert  Company,  a  Delaware  corporation  ("Warner-Lambert")  and  WLC
Acquisition Corporation,  a California corporation and a wholly owned subsidiary
of  Warner-Lambert  ("Merger  Sub"),  have entered into an Agreement and Plan of
Merger,  dated as of January 26, 1999 (the "Merger  Agreement"),  whereby Merger
Sub will be merged with and into the Company,  with the Company as the surviving
entity (the "Merger").

              As a result  of the  Merger,  each  outstanding  share of  Agouron
Common Stock will be converted into shares of common stock,  par value $1.00 per
share,  of  Warner-Lambert  ("Warner-Lambert  Common Stock") at an exchange rate
equal  to  $60.00  divided  by  the  average  of the  closing  sales  prices  of
Warner-Lambert   Common  Stock  on  the  New  York  Stock   Exchange   Composite
Transactions Tape on each of the 10 consecutive trading days up to and including
the second  immediately  preceding  trading  day prior to the date of  Agouron's
Stockholders Meeting. In no event will the exchange rate be more than .9300, nor
less than .8108,  of a share of  Warner-Lambert  Common  Stock for each share of
Agouron Common Stock. Each outstanding option for shares of Agouron Common Stock
will be converted into options for the number of shares of Warner-Lambert Common
Stock  that would have been  received  if such  options  and  warrants  had been
exercised immediately prior to the Merger.

              The  closing  of the  Merger is  subject  to  certain  conditions,
including the approval of the common stockholders of the Company and the receipt
of customary antitrust clearance.

              Concurrently  with  the  execution  and  delivery  of  the  Merger
Agreement,  the Company and Warner-Lambert entered into a Stock Option Agreement
(the "Stock Option Agreement"). Under the Stock Option Agreement, Warner-Lambert
does not have the right to acquire  any shares of Agouron  Common  Stock  unless
certain  specified  events  occur.  If the  option  were to become  exercisable,
Warner-Lambert  would be  entitled  to  purchase  upon  exercise  of the  option
(subject to receipt of necessary regulatory approvals) up to approximately 19.9%
of the outstanding  shares of Agouron Common Stock.  The Stock Option  Agreement
provides  Warner-Lambert  with the right, in certain  circumstances,  to require
Agouron to  repurchase  the option and any shares  acquired  by  exercise of the
option and with the right to require  Agouron to  register  the  Agouron  Common
Stock  acquired by or issuable upon exercise of the option under the  Securities
Act of 1933, as amended.

              In connection  with the Merger  Agreement,  the Company's Board of
Directors has resolved to amend its Amended and Restated Rights  Agreement dated
as of  November  10,  1998 in order  to  render  the  rights  issued  thereunder
inapplicable  to the  Merger  Agreement,  the  Stock  Option  Agreement  and the
transactions contemplated thereby.

              A copy of the  press  release,  dated  January  26,  1999,  issued
jointly by the  Company  and  Warner-Lambert,  relating  to the  above-described
transaction is attached as an exhibit to this report and is incorporated  herein
by reference.
