                          INDEPENDENT AUDITORS' REPORT



The Corporate Benefits Committee
Allergan, Inc.:


We have audited the financial statements of the Allergan, Inc. Savings and
Investment Plan (the Plan) as of December 31, 2001 and 2000 and for the year
ended December 31, 2001 as listed in the accompanying index. These financial
statements are the responsibility of the Plan's management. Our responsibility
is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with auditing standards generally accepted
in the United States of America. Those standards require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the net assets available for benefits of the Plan as of
December 31, 2001 and 2000 and the changes in net assets available for plan
benefits for the year ended December 31, 2001 in conformity with accounting
principles generally accepted in the United States of America.

Our audits were performed for the purpose of forming an opinion on the basic
financial statements taken as a whole. The supplemental schedule of the
Allergan, Inc. Savings and Investment Plan as listed in the accompanying index
is presented for the purpose of additional analysis and is not a required part
of the basic financial statements but is supplementary information required by
the Department of Labor's Rules and Regulations for Reporting and Disclosure
under the Employee Retirement Income Security Act of 1974. The supplemental
schedule has been subjected to the auditing procedures applied in the audits of
the basic financial statements and, in our opinion, is fairly stated in all
material respects in relation to the basic financial statements taken as a
whole.

         refer to the Plan document for a more complete description of the
         Plan's provisions.

         (a)      GENERAL

                  The Plan is a defined contribution plan sponsored by Allergan,
                  Inc. (the Company). The Plan was established on July 27, 1989.
                  The Plan is subject to the provisions of the Employee
                  Retirement Income Security Act of 1974 (ERISA). The Plan is
                  qualified under Section 401(a) and (k) of the Internal Revenue
                  Code (Code) of 1986.

                  Under terms of the Plan, eligible United States employees may
                  voluntarily elect to contribute:

                  1.       Before-tax dollars up to the lesser of 20% of their
                           defined compensation or $10,500 for the year ended
                           December 31, 2001 under the provision 401(k) and

                           contributions, under provision 401(a) and 401(m) of
                           the IRC or,

                  3.       Any combination of the above two elections; however,
                           the total annual additions (participant
                           contributions, company contributions, and allocated
                           forfeitures) cannot exceed the lesser of 25% of the
                           participant's defined compensation or $35,000 under
                           section 415(c) of the Code.

                  2.       After-tax dollars up to 15% of their defined
                           compensation, when aggregated with before-tax
                           contributions, under Puerto Rico Code or,

                  3.       Any combination of the above two elections; however,
                           the total annual additions (participant
                           contributions, company contributions, and allocated

                          Notes to Financial Statements

                           December 31, 2001 and 2000


                  Certain limitations imposed by the Internal Revenue Code may
                  have the effect of reducing the level of contributions
                  initially selected by participants who come within the
                  classification of "highly compensated employees" as defined in
                  the Code.

                  Participant contributions are invested in the Allergan, Inc.
                  Common Stock Fund, American Century Stable Asset Fund, INVESCO
                  Balanced Fund, American Century Income and Growth Fund, J.P.
                  Morgan SmartIndex Fund, American Century Ultra Fund, American
                  Funds New Perspective Fund, American Century International
                  Growth Fund, and Franklin Small Cap Growth A Fund, or any
                  combination of the nine funds at the employee's discretion.
                  Company contributions consist of Allergan, Inc. common stock
                  which is invested in the Allergan, Inc. Common Stock Fund.
                  Effective June 1, 2002, participants can elect to diversify
                  Company contributions into the other investment options.

         (c)      INVESTMENT OPTIONS

                  Participants have the right to elect investment options upon
                  enrollment or re-enrollment into the Plan. Additionally,
                  participants may elect to change their investment options and
                  transfer their account balances among the different investment
                  funds.


         (d)      PARTICIPANT ACCOUNTS

                  Each participant's account is charged for the participant's
                  withdrawals and credited for the participant's contributions,
                  employer contributions, and an allocation of fund earnings.
                  The earnings of each of the funds are allocated daily to the
                  individual accounts of participants based on their relative
                  interest in the fair value of the assets held in each fund,
                  except for dividends and unrealized appreciation
                  (depreciation) on the common stock of Allergan, Inc., which is
                  allocated based upon the number of shares held in the
                  individual accounts of participants.

         (e)      PARTICIPANT LOANS RECEIVABLE

                  Participants may borrow from their fund accounts a minimum of
                  $1,000 up to a maximum equal to the lesser of $50,000 or 50%
                  of their vested account balance. Loan terms range from 1-5
                  years or up to 30 years for the purchase of a primary
                  residence. The loans are secured by the balance in the
                  participant's account and bear interest at prime plus 1% as
                  determined on the date of the loan application. The interest
                  rate is fixed for the term of the loan. Principal and interest
                  is paid through payroll deductions each pay period.

         (f)      VESTING AND FORFEITURES

                  Employee contributions are fully vested at all times.
                  Participants forfeit their share of employer contributions if
                  they withdraw their employee contributions after having
                  completed less than three years of service with the Company.
                  Forfeitures are used by the Company to offset future
                  contribution requirements. In 2001, forfeitures totaled
                  $417,123.

         (g)      WITHDRAWALS

                  Participants may withdraw employee "after-tax" contributions
                  during employment. However, except for financial hardship or
                  emergency (as defined in the Plan), even participants who are
                  fully vested are not eligible to withdraw any portion of
                  employer contributions credited to them within the prior
                  two-year period, although such contributions may be withdrawn
                  at a later date. Withdrawals of employee "after-tax"
                  contributions and employer contributions during employment may
                  cause the employee to become ineligible to receive Company
                  matching contributions and be suspended from contributing to
                  the Plan for a period of six months following the withdrawal.

                           SAVINGS AND INVESTMENT PLAN

                          Notes to Financial Statements

                           December 31, 2001 and 2000



                  Prior to age 59 1/2, employee "before-tax" contributions may
                  be withdrawn in the event of financial hardship, and after the
                  withdrawal of the value of employee "after-tax" contributions
                  and employer contributions. Hardship withdrawals cause the
                  employee to become ineligible to contribute to the Plan for a
                  period of twelve months following the withdrawal.

                  Participants become entitled to payment of the total value of
                  their accounts at the time of termination (if fully vested),
                  attainment of age 62, permanent and total disability, or
                  death. After death, payment is in the form of a lump sum;
                  otherwise, under certain circumstances set forth in the Plan,
                  the participant may elect to receive the distribution in a
                  lump sum (in cash or in cash and common stock of Allergan,
                  Inc.) or may elect annuity payments. If an extended payment
                  option is selected and the participant's account value is
                  $5,000 or more, participants may postpone their withdrawal
                  until as late as attaining age 70 1/2.

         (h)      CONTINUATION OF THE PLAN

                  The Company anticipates and believes the Plan will continue
                  without interruption but reserves the right to discontinue the
                  Plan. If the Plan is terminated by the Company, the accounts
                  of all affected participants shall become 100% vested and
                  nonforfeitable without regard to the years of service of such
                  participants.

(2)      SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

         (a)      BASIS OF PRESENTATION

                  The accompanying financial statements have been prepared on
                  the accrual basis of accounting. The net assets of the Plan
                  are allocated entirely to individual participant accounts. The
                  preparation of financial statements requires the use of plan
                  administrator estimates.

         (b)      INVESTMENTS

                  Investments are stated at fair value. The fair value of
                  Allergan, Inc. common stock is based upon quotations obtained
                  from the New York Stock Exchange. The fair values of the
                  INVESCO Balanced Fund, American Century Income and Growth
                  Fund, J.P. Morgan SmartIndex Fund, American Century Ultra
                  Fund, American Funds New Perspective Fund, American Century
                  International Growth Fund, and Franklin Small Cap Growth A
                  Fund are based upon quotations obtained from the National
                  Association of Security Dealers Automated Quotations (NASDAQ).
                  The fair value of the American Century Stable Asset Fund is
                  based upon the net asset value reported by the fund.
                  Participant loans are valued at cost, which approximates fair
                  value.

                  Purchases and sales of investments are reflected on the
                  trade-date basis. Dividend income is recorded on the
                  ex-dividend date.

                  The Plan presents in the statement of changes in net assets
                  available for plan benefits the net appreciation
                  (depreciation) in the fair value of its investments, which
                  consists of the realized gains or losses and the unrealized
                  appreciation (depreciation) on those investments.

(5)      FEDERAL INCOME TAXES

         The Plan obtained its latest determination letter on September 24, 1999
         in which the Internal Revenue Service stated that the Plan, as then
         designed, was in compliance with the applicable requirements of the
         Internal Revenue Code. The Plan administrator and the Plan's tax
         counsel believe that the Plan is currently designed and being operated
         in compliance with the applicable requirements of the Internal Revenue
         Code.

         Employer contributions and dividends, interest, capital gains, or other
         distributions with respect to assets held by the trustee are not
         taxable to the employee until withdrawn from the Plan.

(6)      OUTSTANDING COMMITMENTS TO PARTICIPANTS

         At December 31, 2001 and 2000, the Plan had not been requested to pay
         withdrawals and distributions to terminated and withdrawing
         participants.

(7)      EMPLOYEE STOCK OWNERSHIP PLAN TRANSFERS

         In accordance with the Internal Revenue Code Section 401(a)(28)(B),
         participants in an Employee Stock Ownership Plan (ESOP) are eligible to
         diversify a portion of their balance if they are 55 years of age or
         older and have been a participant of the Plan for at least 10 years.
         During the first five years of eligibility, participants may direct up
         to 25% of their ESOP balance into the various investment options
         offered in the Savings and Investment Plan. In the sixth year of
         eligibility, participants may direct up to 50% of their ESOP balance
         into the various options offered in the Savings and Investment Plan. In
         the current year, there were $473,566 in transfers from the ESOP to the
         Savings and Investment Plan.

(8)      SUBSEQUENT EVENT

         In January 2002, Allergan, Inc. announced that its board of directors
         approved the separation of its pharmaceutical and optical medical
         device business into two independent companies by spinning off the
         ophthalmic surgical and contact lens care businesses into a new entity
         called Advanced Medical Optics, Inc. (AMO). In connection with the spin
         off, the assets and liabilities of former participants in the Plan will
         be transferred to the Advanced Medical Optics, Inc. 401(k) Plan. AMO
         employees will not be eligible thereafter to make contributions to the
         Plan.
