                          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, 1997 and 1996, and for the year
ended December 31, 1997, 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 generally accepted auditing
standards. 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, 1997 and 1996, and the changes in net assets available for plan
benefits for the year ended December 31, 1997 in conformity with generally
accepted accounting principles.

Our audits were performed for the purpose of forming an opinion on the basic
financial statements taken as a whole. The supplemental schedules of the
Allergan, Inc. Savings and Investment Plan as listed in the accompanying index
are presented for the purpose of additional analysis and are not a required part
of the basic financial statements but are 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 fund information
in the statement of net assets available for plan benefits and the statement of
changes in net assets available for plan benefits is presented for purposes of
additional analysis rather than to present the net assets available for plan
benefits and changes in net assets available for plan benefits of each fund. The
supplemental schedules and fund information have been subjected to the auditing
procedures applied in the audits of the basic financial statements and, in our
opinion, are fairly stated in all material respects in relation to the basic
financial statements taken as a whole.

                          Notes to Financial Statements
                           December 31, 1997 and 1996


(1)     Description of the Plan

        The following description of the Allergan, Inc. Savings and Investment
        Plan ("the Plan") provides only general information. Participants should
        refer to the Plan agreement for a more complete description of the
        Plan's provisions.

               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 (b) of the Internal Revenue Code of 1986.

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

               (1)    "After-tax" dollars up to 15% of their defined
                      compensation under provision 401(a) of the Internal
                      Revenue Code or,

               (2)    "Before-tax" dollars up to the lesser of 10% of their
                      defined compensation or $9,500 for the years ended
                      December 31, 1997 and 1996, under provision 401(k) of the
                      Internal Revenue Code or,

               (3)    Any combination of the above two elections; however, the
                      total contribution cannot exceed the lesser of 15% of
                      their defined compensation or $30,000.

               Contributions

               Effective March 1, 1995, the Company contributes an amount equal
               to 75% of each employee's contribution on the first 2% of defined
               compensation, 50% of each employee's contribution on the next 1%
               of defined compensation and 25% of each employee's contribution
               on the next 2% of defined compensation.

               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, the Balanced Fund, the Interest Income Fund,
               the Growth and Income Fund, the Global Equity Fund or the
               Aggressive Growth Fund, or any combination of the six funds at
               the employee's discretion. Company contributions consist of
               Allergan, Inc. Common Stock which are invested in the Allergan,
               Inc. Common Stock Fund except, after participants reach age 55,
               they may elect to have Company contributions, both past and
               current, invested in any of the funds.

               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.

               pay period.

               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. Forfeitures available for offset of future
               contribution requirements totaled $83,513 at December 31, 1997.

               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 in the Plan
               for a period of six months following the withdrawal.

               Prior to age 59 1/2, employee "before-tax" contributions may only
               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.

               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

               Basis of Presentation

               The accompanying financial statements have been prepared on an
               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.

               The Plan allows the Trustee (Mellon Bank) to combine Plan assets
               with the assets of the Allergan, Inc. Puerto Rico Savings and
               Investment Plan. The accompanying financial statements and
               supplemental schedules represent an allocation of the amounts
               reported by the Trustee related to the Plan.

               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 American Balanced
               Fund, Investment Company of America Fund, Twentieth Century Ultra
               Fund, Interest Income Fund and New Perspective Fund are based
               upon the net asset value reported by the funds. Participant loans
               are valued at cost which approximates fair value.

               Investments in group contracts with banks are stated at cost
               (contract value), which approximates market. Contract value
               represents contributions, net of distributions made under the
               Plan, plus interest at the contract rate.

               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.

               Interest Bearing Cash and Cash Equivalents

               Interest bearing cash and cash equivalents represent amounts
               invested in Mellon Bank's EB Temporary Investment Fund which
               consists of highly liquid short-term investments.

               Administrative Expenses

               Certain administrative expenses of the Plan are paid by the
               Company.

(4)     Federal Income Taxes

        The Plan obtained its latest determination letter on February 12, 1996,
        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.

(5)     Outstanding Commitments to Participants

        At December 31, 1997 and 1996, the Plan had not been requested to pay
        withdrawals and distributions to terminated and withdrawing
        participants.

                          INDEPENDENT AUDITORS' REPORT


The Corporate Benefits Committee
Allergan, Inc.:


We have audited the financial statements of the Allergan, Inc. Puerto Rico
Savings and Investment Plan (the "Plan") as of December 31, 1997 and 1996, and
for the year ended December 31, 1997, 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 generally accepted auditing
standards. 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, 1997 and 1996, and the changes in net assets available for plan
benefits for the year ended December 31, 1997 in conformity with generally
accepted accounting principles.

Our audits were performed for the purpose of forming an opinion on the basic
financial statements taken as a whole. The supplemental schedules of the
Allergan, Inc. Puerto Rico Savings and Investment Plan as listed in the
accompanying index are presented for the purpose of additional analysis and are
not a required part of the basic financial statements but are 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 fund information in the statement of net assets available for plan
benefits and the statement of changes in net assets available for plan benefits
is presented for purposes of additional analysis rather than to present the net
assets available for plan benefits and changes in net assets available for plan
benefits of each fund. The supplemental schedules and fund information have been
subjected to the auditing procedures applied in the audits of the basic
financial statements and, in our opinion, are fairly stated in all material
respects in relation to the basic financial statements taken as a whole.

                          Notes to Financial Statements
                           December 31, 1997 and 1996



(1)     Description of the Plan

        The following description of the Allergan, Inc. Puerto Rico Savings and
        Investment Plan (the "Plan") provides only general information.
        Participants should refer to the Plan document for a more complete
        description of the Plan's provisions.

               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 1165(a) and (e) of the Puerto Rico Income Tax Act of 1954
               and Section 401(a) and (b) of the Internal Revenue Code of 1986.

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

               (1)    "After-tax" dollars up to 15% of their defined
                      compensation under provision 401(a) of the Internal
                      Revenue Code or,

               (2)    "Before-tax" dollars up to the lesser of 10% of their
                      defined compensation or $7,500 for the years ended
                      December 31, 1997 and 1996, under provision 1165(e) of the
                      Puerto Rico Income Tax Act or,

               (3)    Any combination of the above two elections; however, the
                      total contribution cannot exceed the lesser of 15% of
                      their defined compensation or $30,000.

               Contributions

               Effective March 1, 1995, the Company contributes an amount equal
               to 75% of each employee's contribution on the first 2% of defined
               compensation, 50% of each employee's contribution on the next 2%
               of defined compensation and 25% of each employee's contribution
               on the next 2% of defined compensation.

               Certain limitations imposed by the Internal Revenue Code and the
               Puerto Rico Income Tax Act of 1954 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, the Balanced Fund, the Interest Income Fund,
               the Growth and Income Fund, the Global Equity Fund or the
               Aggressive Growth Fund, or any combination of the six funds at
               the employee's discretion. Company contributions consist of
               Allergan, Inc. Common Stock and are invested in the Allergan,
               Inc. Common Stock Fund except, after participants reach age 55,
               they may elect to have Company contributions, both past and
               current, invested in any of the funds.

               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.
                                                                    (continued)

                         Notes to Financial Statements
                           December 31, 1997 and 1996


               Participant Loans Receivable

               Participants may borrow from their fund accounts a minimum of
               $500 up to a maximum equal to the lesser of $50,000 or 50% of
               their vested account balance. Loan transactions are treated as a
               transfer to (from) the investment fund from (to) the participant
               loans fund. Loan terms range from 1-5 years or up to 15 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 one percent as determined on the date of loan application.
               The interest rate is fixed for the term of the loan. Principal
               and interest is paid through payroll deductions each pay period.

               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. Forfeitures available for offset of future
               contribution requirements totaled $9,163 at December 31, 1997.

               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 in the Plan
               for a period of six months following the withdrawal.

               Prior to age 59 1/2, employee "before tax" contributions may only
               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, participants may postpone their withdrawal until as
               late as attaining age 70 1/2 and, in the interim, all fund values
               are transferred to the Interest Income Fund at the time of
               termination.

               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.

                         Notes to Financial Statements

(2)     Summary of Significant Accounting Policies

               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.

               The Plan allows the Trustee (Mellon Bank) to combine Plan assets
               with the assets of the Allergan, Inc. Savings and Investment
               Plan. The accompanying financial statements and supplemental
               schedules represent an allocation of the amounts reported by the
               Trustee related to the Plan.

               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 American Balanced
               Fund, Investment Company of America Fund, Twentieth Century Ultra
               Fund, Interest Income Fund and the New Perspective Fund are based
               upon the net asset value reported by the funds.

               Investments in group contracts with banks are stated at cost
               (contract value), which approximates market. Contract value
               represents contributions, net of distributions made under the
               Plan, plus interest at the contract rate.

               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.

               Interest Bearing Cash and Cash Equivalents

               Interest bearing cash and cash equivalents represent amounts
               invested in Mellon Bank's EB Temporary Investment Fund which
               consists of highly liquid short-term investments.

               Administrative Expenses

               Certain administrative expenses of the Plan are paid by the
               Company. 

                                                                  (continued)

        The Plan is intended to constitute a profit sharing plan qualified under
        Section 1165(e) of the Puerto Rico Income Tax Act of 1954 and Section

        designed, was in compliance with the applicable requirements of the
        Internal Revenue Code.
