                                  JANUARY 2002

PURPOSE OF THE PLAN

The 2002 AMO Pre-Spin Management Bonus Plan (the "Plan") is designed to reward
eligible management-level employees for their contributions to providing
Allergan's stockholders increased value for their investment through the
successful accomplishment of specific financial objectives and individual
performance objectives.

PLAN TERM

The Plan term runs from January 1, 2002 through the date on which Advanced
Medical Optics, Inc. ("AMO") is spun off from Allergan (the "Spin Date"). If the
Spin Date has not occurred by December 31, 2002, no participants will receive
bonuses under this Plan and will instead be eligible for bonuses under the
Allergan, Inc. 2002 Management Bonus Plan

ELIGIBILITY

All regular full-time and part-time employees of Allergan, Inc. and its
subsidiaries (the "Company") scheduled to work 20 or more hours per week in
salary grades 7E and above who are not covered by any other bonus or sales
incentive plan and whose employment transfers to AMO on the Spin Date are
eligible to participate in the Plan. Notwithstanding anything in this Plan to
the contrary, any individual shall not be eligible to participate in the Plan if
such individual (a) performs services for the Company and 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 (b) performs services for
the Company pursuant to an agreement between the Company and any other person
including a leasing organization. Participants must be employed by the Company
on or before the Spin Date. Participants must be actively employed by AMO on the
date bonuses are paid in 2003 in order to be eligible to receive a bonus.
Participants who resign or are terminated for reasons other than those noted
below will receive no bonus.

Bonuses, if any, for participants who become employed by the Company and
eligible after the beginning of the plan term will be prorated.

PERFORMANCE OBJECTIVES

Bonuses for Plan participants are based on both corporate performance and
individual performance in relation to pre-established objectives, as follows:

CORPORATE OBJECTIVE FOR AMO

Corporate performance for the AMO businesses is measured in terms of worldwide
Pre-Tax Income of the AMO businesses (the "Financial Goal").

INDIVIDUAL OBJECTIVES

     Management Bonus Objectives (MBOs) are prepared by each participant and his
     or her supervisor at the beginning of the Plan year and may be modified
     throughout the year as necessary. Objectives should reflect major results
     and accomplishments to be achieved in order to meet short- and long-term
     business goals that contribute to increased stockholder value. MBOs are
     expressed as specific, quantifiable measures of performance in relation to
     key operating decisions for the participant's business unit, such as
     managing inventory levels, receivables, expenses, or payables; increasing
     sales; eliminating unnecessary capital expenditures, etc.

--------------------------------------------------------------------------------
January 2002                                                            Page -1-
<PAGE>

     At the end of the Plan year, the supervisor evaluates the participant's
     performance in relation to his or her objectives in order to determine the
     size of the bonus award, if any. A more detailed description of how the
     award is calculated is provided under "Individual Bonus Award Calculation."

BONUS POOL CALCULATION

BONUS POOL FUNDING - Bonuses are funded when the AMO businesses achieve the
                     threshold level of Financial Goal performance. The level of
                     bonus funding is determined by Financial Goal performance
                     as outlined in the table below.

               If actual Financial Goal results fall between the performance
               levels shown above, bonuses will be prorated accordingly.

At the end of the Plan term, the President and Chief Executive Officer of
Allergan, Inc. may recommend adjustments to the bonus funding levels to the
Organization and Compensation Committee (the "Committee") after consideration of
key operating results. When calculating Financial Goal performance for purposes
of this Plan, the Committee has the discretion to include or exclude any or all
of the following items:

o    extraordinary, unusual or non-recurring items

o    effects of accounting changes

o    effects of financing activities

o    expenses for restructuring or productivity initiatives

o    other non-operating items

o    spending for acquisitions

o    effects of divestitures

INDIVIDUAL BONUS AWARD CALCULATION

Target bonus awards are expressed as a percentage of the participant's year-end
annualized base salary. The target percentages vary by salary grade (see
Attachment No. 1).

A participant's actual bonus award may vary above or below the targeted level
based on the supervisor's evaluation of his or her performance in relation to
the predetermined MBOs. Each participant may receive from 0% up to 150% of his
or her target bonus amount. However, the total of all bonus awards given within
each business unit must total no more than 100% of the total bonus pool dollars
allocated to that business unit.

METHOD OF PAYMENT

Cash awards are paid in 2003 after the review and authorization of bonuses by
the Committee and by the AMO Board of Directors or a committee thereof. In the
event of a Change in Control (as defined in Attachment No. 2) before the Spin
Date, bonuses will be paid within 30 days of the effective date of the Change in
Control.

<PAGE>

CHANGE IN CONTROL

If a Change in Control of Allergan occurs during the Plan term or if Allergan
sells the AMO businesses before the Spin Date, participants will be paid a bonus
prorated to the effective date of the Change in Control or sale and Financial
Goal performance will be deemed to be the greater of:

o    100% of the Financial Goal or

o    the prorated actual year-to-date Financial Goal performance

In either case, a participant's actual bonus may vary above or below the
targeted level according to the provisions outlined in "Individual Bonus Award
Calculation" above. Participants must be employed by the Company or its
successor on the effective date of the Change in Control or sale in order to
receive the prorated payment, unless their employment is terminated for
retirement, death, disability or otherwise without cause. For purposes of this
Plan, "cause" shall be limited to only three types of events: the willful
refusal to comply with a lawful, written instruction of the Board so long as the
instruction is consistent with the scope and responsibilities of the
participant's position prior to the Change in Control or sale; dishonesty which
results in a material financial loss to the Company (or to any of its affiliated
companies) or material injury to its public reputation (or to the public
reputation of any of its affiliated companies); or conviction of any felony
involving an act of moral turpitude.

GENERAL

Management reserves the right to define corporate performance and individual
performance and to review, alter, amend, or terminate the Plan at any time. This
Plan does not constitute a contract of employment and cannot be relied upon as
such. Any questions regarding this Plan should be directed to the Human
Resources department or the Vice President, Compensation. This Management Bonus
Plan document supersedes any previous document you may have received.

                          CHANGE IN CONTROL DEFINITION

"Change in Control" shall mean the following and shall be deemed to occur if any
of the following events occur:

               (a) Any "person," as such term is used in Sections 13(d) and
14(d) of the Securities Exchange Act of 1934, as amended (the "Exchange Act") (a
"Person"), is or becomes the "beneficial owner," as defined in Rule 13d-3 under
the Exchange Act (a "Beneficial Owner"), directly or indirectly, of securities
of Allergan, Inc., a Delaware corporation ("Allergan") representing (i) 20% or
more of the combined voting power of Allergan's then outstanding voting
securities, which acquisition is not approved in advance of the acquisition or
within 30 days after the acquisition by a majority of the Incumbent Board (as
hereinafter defined) or (ii) 33% or more of the combined voting power of
Allergan's then outstanding voting securities, without regard to whether such
acquisition is approved by the Incumbent Board;

               (b) Individuals who, as of the date hereof, constitute the Board
of Directors of Allergan (the "Incumbent Board"), cease for any reason to
constitute at least a majority of the Board of Directors, provided that any
person becoming a director subsequent to the date hereof whose election, or
nomination for election by Allergan's stockholders, is approved by a vote of at
least a majority of the directors then comprising the Incumbent Board (other
than an election or nomination of an individual whose initial assumption of
office is in connection with an actual or threatened election contest relating
to the election of the directors of Allergan, as such terms are used Rule 14a-11
of Regulation 14A promulgated under the Exchange Act) shall, for the purposes of
this Agreement, be considered as though such person were a member of the
Incumbent Board of Allergan;

               (c) The consummation of a merger, consolidation or reorganization
involving Allergan, other than one which satisfies both of the following
conditions:

                    (1) a merger, consolidation or reorganization which would
result in the voting securities of Allergan outstanding immediately prior
thereto continuing to represent (either by remaining outstanding or by being
converted into voting securities of another entity) at least 55% of the combined
voting power of the voting securities of Allergan or such other entity resulting
from the merger, consolidation or reorganization (the "Surviving Corporation")
outstanding immediately after such merger, consolidation or reorganization and
being held in substantially the same proportion as the ownership in Allergan's
voting securities immediately before such merger, consolidation or
reorganization, and

                    (2) a merger, consolidation or reorganization in which no
Person is or becomes the Beneficial Owner directly or indirectly, of securities
of Allergan representing 20% or more of the combined voting power of Allergan's
then outstanding voting securities; or

               (d) The stockholders of Allergan approve a plan of complete
liquidation of Allergan or an agreement for the sale or other disposition by
Allergan of all or substantially all of Allergan's assets.

Notwithstanding the preceding provisions of this Section, a Change in Control
shall not be deemed to have occurred if the Person described in the preceding
provisions of this Section is (1) an underwriter or underwriting syndicate that
has acquired the ownership of any of Allergan's then outstanding voting
securities solely in connection with a public offering of Allergan's securities,
(2) Allergan or any subsidiary of Allergan or (3) an employee stock ownership
plan or other employee benefit plan maintained by Allergan (or any of its
affiliated companies) that is qualified under the provisions of the Internal
Revenue Code of 1986, as amended. In addition, notwithstanding the preceding
provisions of this Section, a Change in Control shall not be deemed to have
occurred if the Person described in the preceding provisions of this Section
becomes a Beneficial Owner of more than the permitted amount of outstanding
securities as a result of the acquisition of voting securities by Allergan
which, by reducing the number of voting securities outstanding, increases the
proportional number of shares beneficially owned by such Person, provided, that
if a Change in Control would occur but for the operation of this sentence and
such Person becomes the Beneficial Owner of any additional voting securities
(other than through the exercise of options granted under any stock option plan
of Allergan or through a stock dividend or stock split), then a Change in
Control shall occur.

                                 ALLERGAN, INC.

                      EXECUTIVE DEFERRED COMPENSATION PLAN
                           (RESTATED JANUARY 1, 2000)

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

I. Section 5.3 of the Plan, entitled Participant Investment Elections, is hereby
amended by amending subsection (c), adding new subsection (d), and by
redesignating existing subsection (d) as subsection (e):

                  (c) Transfers from Company Rate to Fund Rate on or after March
         1, 2002. Each Participant may request to change the investment of all
         or any portion of his or her Deferral Account from the Company Rate to
         the Fund Rate as of each January 1 or July 1 ("Transfer Date") subject
         to the following conditions:

                           (1) An Investment Election Form, which includes the
                  allocation among Fund Media, must be submitted prior to the
                  Transfer Date by such time as may be established by the
                  Committee from time to time.

                           (2) For any Transfer Date, the amount of requests for
                  investment transfers (when added to the amount of requests for
                  Financial Hardship withdrawals and Unscheduled Withdrawals
                  from portions of Deferral Accounts subject to the Company
                  Rate) may not exceed 25% of the aggregate amount of all
                  Deferral Accounts invested at the Company Rate. If the 25%
                  aggregate limit is exceeded, requests will be granted under a
                  hierarchy established by the Committee taking into account, in
                  the following order of preference: (i) Financial Hardship
                  withdrawals, (ii) Unscheduled Withdrawals, and (iii)
                  investment transfers.

                           (3) An investment transfer from the Company Rate to
                  the Fund Rate shall be irrevocable.

                  (d) Transfers from Company Rate to Fund Rate prior to March 1,
         2002. Each Participant may elect to change the investment of all or any
         portion of his or her Deferral Account from the Company Rate to the
         Fund Rate, but may not change from the Fund Rate to the Company Rate.
         The Participant shall make such election, including the allocation
         among Fund Media, by submitting an Investment Election Form.

II. Section 11.1 of the Plan is hereby amended in its entirety to read as
follows:

                  11.1 Unscheduled Withdrawals. A Participant may take
         Unscheduled Withdrawals (but no more than one in any Plan Year) from
         his or her Deferral

<PAGE>

         Account. The amount of any Unscheduled Withdrawal shall be equal to the
         portion of the Deferral Account attributable to one or more Deferral
         Elections that have been previously completed and shall include (i)
         interest credited, to the extent that the Company Rate applies, at the
         Company Rate, and (ii) investment earnings, to the extent that the Fund
         Rate applies, at the Fund Rate. In any case where an Unscheduled
         Withdrawal occurs, the Participant may select, if applicable, whether
         such amounts will be from the portion of the Deferral Account invested
         at the Company Rate, if any, or the Fund Rate. Effective March 1, 2002,
         to the extent a Participant selects his or her Unscheduled Withdrawal
         from the portion of his or her Deferral Account invested at the Company
         Rate, that portion of the withdrawal shall be paid at the time and
         subject to the limits set forth in Section 5.3(c). The Committee may
         establish the date by which an Unscheduled Withdrawal from the portion
         of his or her Deferral Account invested at the Company Rate must be
         requested in order to process the request in a timely manner.

III. Section 11.2 of the Plan is hereby amended in its entirety to read as
follows:

                  11.2 Financial Hardship Withdrawal. A Participant may request
         that the Committee permit him or her to take a withdrawal or
         withdrawals on account of Financial Hardship (as defined in Section
         2.21). In such event, the Committee shall determine in its sole
         discretion whether a Financial Hardship exists and, if it so
         determines, whether the Participant should be permitted to take such a
         withdrawal. The Committee shall also determine the amount of the
         permitted withdrawal, which shall not exceed the amount necessary to
         address the Financial Hardship, and whether the Participant must reduce
         or cease a current Deferral Election, if any, as a condition for a
         Financial Hardship withdrawal. Effective March 1, 2002, to the extent a
         Financial Hardship withdrawal is from the portion of a Participant's
         Deferral Account invested at the Company Rate, that portion of the
         withdrawal shall be paid at the time subject to the limits set forth in
         Section 5.3(c). The Committee may establish the date by which a
         Financial Hardship withdrawal from the portion of his or her Deferral
         Account invested at the Company Rate must be requested in order to
         process the request in a timely manner.

         IN WITNESS WHEREOF, Allergan, Inc. hereby executes this Third Amendment
on this 25th day of February, 2002.
