                        THIRD AMENDMENT TO ALLERGAN, INC.
                          PENSION PLAN (RESTATED 1996)

The ALLERGAN, INC. PENSION PLAN (the "Plan") is hereby amended to read as
follows:

1. The definition of the term "Employee" in Section 1.1 of the Plan is amended
   in its entirety, as follows:

                  "'Employee' means a person who is employed by or is an
         officer of the Company or an Affiliate, any portion of whose income is
         subject to withholding of income tax and/or for whom Social Security
         contributions are made by the Company or an Affiliate, except that such
         term shall not include (a) any individual who performs services for the
         Company or an Affiliate and who is classified or paid as an independent
         contractor (regardless of his or her classification for federal tax or
         other legal purposes) by the Company or Affiliate and (b) any
         individual who performs services for the Company or an Affiliate
         pursuant to an agreement between the Company or Affiliate and any other
         person including a leasing organization except to the extent such
         individual is a Leased Employee."

2. The definition of the term "Eligible Employee" in Section 1.1 of the Plan is
   amended in its entirety as follows:

                  "'Eligible Employee' means an Employee who is employed by the
         Company or by an Affiliate designated by the Board of Directors of
         Allergan, but not by a joint venture in which the Company or such
         Affiliate is a joint venturer; provided, that an Employee with respect
         to whom retirement benefits have been the subject of good faith
         collective bargaining shall be an Eligible Employee only to the extent
         a collective bargaining agreement relating to him so provides. An
         Employee of an Affiliate or of the Company who is a Leased Employee, or
         who is neither a United States citizen nor a United States resident,
         shall not be an Eligible Employee. Notwithstanding the preceding
         sentence, for Plan Years beginning prior to January 1, 1996, an
         Eligible Employee shall not include a temporary employee classified as
         such by the Affiliate or the Company."

3. The effective date of this Third Amendment shall be January 1, 1999.

         IN WITNESS WHEREOF, Allergan, Inc. hereby executes this Third Amendment
on the 26th day of August, 1999.
