I.  GENERAL PROVISIONS
 
1.1    PURPOSES OF THE PLAN
 
       Allergan, Inc. ("Allergan") has adopted this 1989 Incentive Compensation
Plan (the "Plan") to advance the interests of Allergan and its stockholders by
affording to key management and other Employees of Allergan and its subsidiaries
an opportunity to acquire or increase a proprietary interest in the Company or
to otherwise benefit from the success of the Company through the grant to such
Employees of Incentive Awards under the terms and conditions set forth herein.
By thus encouraging such Employees to become owners of Allergan's shares and by
granting such Employees other incentive compensation that is measured by the
increased market value of Allergan's shares or another appropriate measure of
the success and profitability of the Company, the Company seeks to attract,
retain and motivate those highly competent individuals upon whose judgment,
initiative, leadership and continued efforts the success of the Company in large
measure depends.

1.4    ADMINISTRATION OF THE PLAN
 
       (a) The Plan will be administered by the Committee, which will consist of
two or more persons appointed by the Board (i) who are not eligible to receive
Incentive Awards under the Plan and (ii) who have not been eligible at any time
within one year before appointment to the Committee for selection as persons to
whom Incentive Awards may be granted pursuant to the Plan, or to whom shares may
be allocated, or stock options, stock appreciation rights or similar rights may
be granted, pursuant to any other discretionary plan of Allergan (or any
affiliate thereof, within the meaning of the Exchange Act and the regulations
thereunder) entitling the participants therein to acquire stock, stock options,
stock appreciation rights or similar rights of Allergan (or any affiliate
thereof, within the meaning of the Exchange Act and the regulations thereunder).
Notwithstanding anything contained herein, no person shall be disqualified from
being a member of the Committee merely because such person is entitled to
receive grants of restricted stock pursuant to the Allergan, Inc. 1989
Nonemployee Director Stock Plan or any successor thereto providing for the
automatic grant, without the intervention of any administrative discretion, of
stock options, restricted stock or other stock-based incentive compensation
awards.
 
       (b) The Committee has and may exercise such powers and authority of the
Board as may be necessary or appropriate for the Committee to carry out its
functions as described in the Plan. The Committee has authority in its
discretion to select the eligible Employees to whom, and the time or times at
which, Incentive Awards shall be granted or sold, the nature of each Incentive
Award, the number of shares of Common Stock or the number of rights that make up
each Incentive Award, the period for the exercise of each Incentive Award, the
performance criteria (which need not be identical) utilized to measure the value
of Performance Awards and such other terms and conditions applicable to each
individual Incentive Award as the Committee shall determine. The Committee may
grant at any time new Incentive Awards to a Participant who has previously
received Incentive Awards or other grants (including other stock options)
whether such prior Incentive Awards or such other grants are still outstanding,
have previously been exercised in whole or in part, or are cancelled in
connection with the issuance of new Incentive Awards. The Committee may grant
Incentive Awards singly or in combination or in tandem with other Incentive
Awards as it determines in its discretion. The purchase price or initial value
and any and all other terms and conditions of the Incentive Awards may be
established by the Committee without regard to existing Incentive Awards or
other grants. Further, the Committee may, with the consent of a Participant,
amend in a manner consistent with the Plan the terms of any existing Incentive
Award previously granted to such Participant.
 
       (c) Subject to the express provisions of the Plan, the Committee has the
authority to interpret the Plan, to determine the terms and conditions of
Incentive Awards and to make all other determinations necessary or advisable for
the administration of the Plan. The Committee has authority to prescribe, amend
and rescind rules and regulations relating to the Plan. All interpretations,
determinations and actions by the Committee shall be final, conclusive and
binding upon all parties. Any action of the Committee with respect to the
administration of the Plan shall be taken pursuant to a majority vote or by the
unanimous written consent of its members.
 
 
                                       6
<PAGE>   7
 
       (d) No member of the Board or the Committee nor any designee thereof will
be liable for any action or determination made in good faith by the Board or the
Committee with respect to the Plan or any transaction arising under the Plan.
 
1.5    PARTICIPATION
 
       (a) All Employees who are key Employees of the Company, as determined by
the Committee, are eligible to receive Incentive Awards under the Plan. In no
event may any member of the Board who is not an Employee be granted an Incentive
Award under the Plan.
 
       (b) At the time of the grant of each Incentive Award pursuant to this
Plan, the Committee shall deliver, or cause to be delivered, to the Participant
to whom the Incentive Award is granted a statement evidencing the Incentive
Award and setting forth such terms and conditions applicable to the Incentive
Award as the Committee may in its discretion determine consistent with the Plan.
 
II.  DIVIDEND EQUIVALENTS
 
       A Participant may in the discretion of the Committee be granted, at no
additional cost, Dividend Equivalents based on the dividends declared on the
Common Stock on record dates during the period between the date an Incentive
Award is granted and the date such Incentive Award is exercised or such other
period as is determined by the Committee and specified in the instrument that
evidences the grant of the Incentive Award. Such Dividend Equivalents shall be
converted to additional shares or cash by such formula as may be determined by
the Committee.
 
       Dividend Equivalents shall be computed as of each dividend record date in
such manner as may be determined by the Committee and shall be payable to
Participants at such time or time as the Committee in its discretion may
determine.
 
III.  OPTIONS
 
3.1    OPTION PRICE
 
       The purchase price of Common Stock under each Option (the "Option
Exercise Price") will be determined by the Committee at the date such Option is
granted. The Option Exercise Price may be less than the Fair Market Value on the
date of grant of the Common Stock subject to the Option; provided, however, that
in no event shall the Option Exercise Price be less than the par value of the
shares of Common Stock subject to the Option; and further provided that in the
case of an Incentive Stock Option the Option Exercise Price shall be not less
than the Fair Market Value on the date of grant of the Common Stock subject to
such Option or such other amount as is necessary to enable such Option to be
treated as an "incentive stock option" within the meaning of Code Section 422A.
 
 
                                       7
<PAGE>   8
 
3.2    OPTION PERIOD
 
       Options may be exercised as determined by the Committee, but, in the case
of an Incentive Stock Option, in no event after ten years from the date of grant
of such Option or such other period as is necessary to enable such Option to be
treated as an "incentive stock option" within the meaning of Code Section 422A.
 
3.3    EXERCISE OF OPTIONS
 
       At the time of the exercise of an Option, the purchase price shall be
paid in full in cash or other equivalent consideration acceptable to the
Committee and consistent with the Plan's purpose and applicable law, including
without limitation Common Stock or Restricted Stock or other contingent awards
denominated in either stock or cash. Any shares of Company Stock assigned and
delivered to the Company in payment or partial payment of the purchase price
will be valued at their Fair Market Value on the exercise date. No fractional
shares will be issued pursuant to the exercise of an Option nor will any cash
payment be made in lieu of fractional shares.
 
3.4    LIMITATION ON EXERCISE OF INCENTIVE STOCK OPTIONS
 
       The aggregate Fair Market Value (determined at the time the Option is
granted) with respect to which Incentive Stock Options are exercisable for the
first time by any Employee during any calendar year (under all stock option
plans of the Company) shall not exceed $100,000 or such other limit as is
prescribed by the Code. Any Options granted as Incentive Stock Options pursuant
to the Plan in excess of such limitation shall be treated as Nonqualified Stock
Options.
 
3.5    TERMINATION OF EMPLOYMENT
 
       (a) Except as otherwise provided in a written agreement between the
Company and the Participant, in the event of the termination of a Participant's
employment with the Company for Cause, all of the Participant's unexercised
Options and/or Rights shall expire as of the date of such termination.
 
       (b) Except as otherwise provided in a written agreement between the
Company and the Participant, in the event of a Participant's termination of
employment for:
 
              (i) Any reason other than for Cause, death, total disability (as
       defined in the instrument evidencing the grant of the Option), normal
       retirement (as defined in the instrument evidencing the grant of the
       Option) or Job Elimination (as defined below), the Participant's Options
       and/or Rights shall expire and become unexercisable as of the earlier of
       (A) the date such Options and/or Rights expire in accordance with their
       terms or (B) three calendar months after the date of termination.
 
              (ii) Death or total disability, effective for terminations after
       July 24, 2000, all of the Participant's unvested Options and/or Rights
       shall become vested as of the last date of
 
 
                                       8
<PAGE>   9
 
       employment, and the Participant (or his or her successor in interest)
       shall have twelve (12) months after the date of termination within which
       to exercise Options and/or Rights that have not expired on or before such
       date, regardless of the date upon which such Options or Rights would
       otherwise expire in accordance with their terms.
 
              (iii) Normal retirement, the Participant's Options and/or Rights
       shall expire and become unexercisable as of the earlier of (A) the date
       such Options and/or Rights expire in accordance with their terms or (B)
       three (3) years after the date of termination.
 
              (iv) Job Elimination, all of the Participant's unvested Options
       and/or Rights shall become vested as of the last date of employment, and
       the Participant's Options and/or Rights shall expire and become
       unexercisable as of the earlier of (A) the date such Options and/or
       Rights expire in accordancd with their terms or (B) three calendar months
       after the date of termination. "Job Elimination" occurs when a Particpant
       ceases to be an Employee of the Company as a result of a reduction in
       force or transfer to a new organization outside of the Company as a
       result of a divestiture. A "reduction in force" occurs under the Plan
       when no alternative job is offered to the Participant at the Company and
       there is a net headcount reduction (i.e. if the Participant is replaced,
       there is no reduction in force, even if the duties of the position
       change).
 
       (c) Notwithstanding anything to the contrary in Paragraphs (a) or (b)
above, the Committee may in its discretion designate such shorter or longer
periods to exercise Options and/or Rights following a Participant's termination
of employment; provided, however, that any shorter periods determined by the
Committee shall be effective only if provided for in the instrument that
evidences the grant to the Participant of such Options and/or Rights or if such
shorter period is agreed to in writing by the Participant. In the case of an
Incentive Stock Option, notwithstanding anything to the contrary herein, in no
event shall such Option be exercisable after the expiration of ten years from
the date such Option is granted (or such other period as is provided in Code
Section 422A). This Plan provides for automatic acceleration of vesting of
Options and/or Rights in the event of a Participant's termination due to death
or total disability after July 24, 2000 or Job Elimination. In all other
situations, with the exception of terminations for Cause, Options and/or Rights
shall be exercisable by a Participant (or his successor in interest) following
such Participant's termination of employment only to the extent that
installments thereof had become exercisable on or prior to the date of such
termination; provided, however, that the Committee, in its discretion, may elect
to accelerate the vesting of all or any portion of any Options and/or Rights
that had not become exercisable on or prior to the date of such termination.

shall expire and terminate unless otherwise determined by the Committee. In the

any, of the Performance Award should be paid to the Participant.

terminating Participant shall have the restrictions lapse on each grant of
Restricted Stock in an amount equal to the number of shares of Restricted Stock
granted multiplied by a fraction, the numerator of which is the number of full
calendar months from the date of grant until the
 
 
                                       11
<PAGE>   12
 
Participant's last day of employment and the denominator of which is the
number of months during which the restriction would have been in effect pursuant
to each original grant. In all other cases, unless the Committee in its
discretion determines otherwise, upon a Participant's termination of employment
for any reason, all of the Participant's Restricted Stock remaining subject to
restrictions imposed pursuant to this Plan on the date of such termination of
employment shall be repurchased by the Company at the Purchase Price (if any).
 
VI.  STOCK APPRECIATION RIGHTS
 
6.1    GRANTING OF STOCK APPRECIATION RIGHTS
 
       The Committee may approve the grant to eligible Employees of Stock
Appreciation Rights related or unrelated to Options, at any time.
 
       (a) A Stock Appreciation Right granted in connection with an Option
granted under this Plan will entitle the holder of the related Option, upon
exercise of the Stock Appreciation Right, to surrender such Option, or any
portion thereof to the extent unexercised, with respect to the number of shares
as to which such Stock Appreciation Right is exercised, and to receive payment
of an amount computed pursuant to Section 6.1(c). Such Option will, to the
extent surrendered, then cease to be exercisable.
 
       (b) Subject to Section 6.1(g), a Stock Appreciation Right granted in
connection with an Option hereunder will be exercisable at such time or times,
and only to the extent that, the related Option is exercisable, and will not be
transferable except to the extent that such related Option may be transferable.
 
       (c) Upon the exercise of a Stock Appreciation Right related to an Option,
the Holder will be entitled to receive payment of an amount determined by
multiplying: (i) the difference obtained by subtracting the Option Exercise
Price of a share of Common Stock specified in the related Option from the Fair
Market Value of a share of Common Stock on the date of exercise of such Stock
Appreciation Right (or as of such other date or as of the occurrence of such
event as may have been specified in the instrument evidencing the grant of the
Stock Appreciation Right), by (ii) the number of shares as to which such Stock
Appreciation Right is exercised.
 
       (d) The Committee may grant Stock Appreciation Rights unrelated to
Options to eligible Employees. Section 6.1(c) shall be used to determine the
amount payable at exercise under such Stock Appreciation Right, except that in
lieu of the Option Exercise Price specified in the related Option the initial
base amount specified in the Incentive Award shall be used.
 
       (e) Notwithstanding the foregoing, the Committee, in its discretion, may
place a dollar limitation on the maximum amount that will be payable upon the
exercise of a Stock Appreciation Right under the Plan.
 
       (f) Payment of the amount determined under the foregoing provisions of
this Section 6.2 may be made solely in whole shares of Common Stock valued at
their Fair Market Value on the date of exercise of the Stock Appreciation Right
or, alternatively, at the sole discretion of the
 
 
                                       12
<PAGE>   13
 
Committee, in cash or in a combination of cash and shares of Common Stock as the
Committee deems advisable. The Committee is hereby vested with full discretion
to determine the form in which payment of a Stock Appreciation Right will be
made and to consent to or disapprove the election of a Participant to receive
cash in full or partial settlement of a Stock Appreciation Right. If the
Committee decides to make full payment in shares of Common Stock, and the amount
payable results in a fractional share, payment for the fractional share will be
made in cash.
 
       (g) The Committee may, at the time a Stock Appreciation Right is granted,
impose such conditions on the exercise of the Stock Appreciation Right as may be
required to satisfy the requirements of Rule 16b-3 under the Exchange Act (or
any other comparable provisions in effect at the time or times in question).
 
6.2    TERMINATION OF EMPLOYMENT
 
       Section 3.5 will govern the treatment of Stock Appreciation Rights upon
the termination of a Participant's employment with the Company.
 
VII.  STOCK PAYMENTS
 
       The Committee may approve Stock Payments of the Company's Common Stock to
any Employee of the Company for all or any portion of the compensation (other
than base salary) that would otherwise become payable to an Employee in cash.
 
VIII.  OTHER PROVISIONS
 
8.1    ADJUSTMENT PROVISIONS
 
       (a) Subject to Section 8.1(b) below, (i) if the outstanding shares of
Common Stock of the Company are increased, decreased or exchanged for a
different number or kind of shares or other securities, or if additional shares
or new or different shares or other securities are distributed in respect of
such shares of Common Stock (or any stock or securities received with respect to
such Common Stock), through merger, consolidation, sale or exchange of all or
substantially all of the properties of the Company, reorganization,
recapitalization, reclassification, stock dividend, stock split, reverse stock
split, spin-off or other distribution with respect to such shares of Common
Stock (or any stock or securities received with respect to such Common Stock),
or (ii) if the value of the outstanding shares of Common Stock of the Company is
reduced by reason of an extraordinary cash dividend, an appropriate and
proportionate adjustment shall be made in (x) the maximum number and kind of
shares provided in Section 1.3 (including the maximum amounts referred to in
Section 1.3(d) and (e)), (y) the number and kind of shares or other securities
subject to then outstanding Incentive Awards, and (z) the price for each share
or other unit of any other securities subject to then outstanding Incentive
Awards. No fractional interests will be issued under the Plan resulting from any
such adjustments.
 
       (b) In addition to the adjustments permitted by Section 8.1(a) above,
except as otherwise expressly provided in the statement evidencing the grant of
an Incentive Award, upon the
 
 
                                       13
<PAGE>   14
 
occurrence of a Change in Control of the Company any outstanding Incentive
Awards not theretofore exercisable, payable or free from restrictions, as the
case may be, shall immediately become exercisable, payable or free from
restrictions (other than restrictions required by applicable law or any national
securities exchange upon which any securities of the Company are then listed),
as the case may be, in their entirety and any shares of Common Stock acquired
pursuant to an Incentive Award which are not fully vested shall immediately
become fully vested, notwithstanding any of the other provisions of the Plan.
 
8.2    SECTION 16 PERSONS
 
       Notwithstanding any other provisions in this Plan, any Incentive Award
granted hereunder to an Employee who is then subject to Section 16 of the
Exchange Act shall be subject to the following limitations:
 
       (a) The Incentive Award may provide for the issuance of shares of Common
Stock as a stock bonus for no consideration other than services rendered or to
be rendered. In the event of an Incentive Award under which shares of Common
Stock are or may in the future be issued for any other type of consideration,
the amount of such consideration shall either (1) be equal to the amount (such
as the par value of such shares) required to be received by the Company in order
to assure compliance with applicable state law, (2) be equal to or greater than
50% of the fair market value of such shares on the date of grant of such
Incentive Award, or (3) in the case of Stock Options granted pursuant to Section
3.6 above, be the amount determined pursuant to the applicable substitution
formula. For such purposes, the fair market value of shares of Common Stock
shall be calculated on the basis of the closing price of stock of that class on
the day in question (or, if such day is not a trading day in the U.S. securities
markets, on the nearest preceding trading day), as reported with respect to the
principal market (or the composite of the markets, if more than one) in which
such shares are then traded, or, if no such closing prices are reported, on the
basis of the mean between the high bid and low asked prices that day on the
principal market or national quotation system on which such shares are then
quoted or, if not so quoted, as furnished by a professional securities dealer
making a market in such shares selected by the Board or the Committee.
 
       (b) Any Stock Option or similar right (including a Stock Appreciation
Right) granted to such Employee pursuant to the Plan shall not be transferable
other than by will or the laws of descent and distribution and shall be
exercisable during such Employee's lifetime only by him or by his guardian or
legal representative. No Incentive Award granted to such Employee and no right
of such Employee under the Plan, contingent or otherwise, will be assignable or
made subject to any encumbrance, pledge or charge of any nature except that,
under such rules and regulations as the Committee may establish pursuant to the
terms of the Plan, a beneficiary may be designated with respect to an Incentive
Award in the event of death of such Employee. If such beneficiary is the
executor or administrator of the estate of the Employee, any rights with respect
to such Incentive Award may be transferred to the person or persons or entity
(including a trust) entitled thereto under the will of such Employee.

8.3    CONTINUATION OF EMPLOYMENT
 
       (a) Nothing in the Plan or in any statement evidencing the grant of an
Incentive Award pursuant to the Plan shall be construed to create or imply any
contract of employment between any Participant and the Company, to confer upon
any Participant any right to continue in the employ of the Company, or to confer
upon the Company any right to require any Participant's continued employment.
Except as expressly provided in the Plan or in any statement evidencing the
grant of an Incentive Award pursuant to the Plan, the Company shall have the
right to deal with each Participant in the same manner as if the Plan and any
such statement evidencing the grant of an Incentive Award pursuant to the Plan
did not exist, including, without limitation, with respect to all matters
related to the hiring, discharge, compensation and conditions of the employment
of the Participant. Unless otherwise expressly set forth in a separate
employment agreement between the Company and such Participant, the Company may
terminate the employment of any Participant with the Company at any time for any
reason, with or without cause.
 
       (b) Any question(s) as to whether and when there has been a termination
of a Participant's employment, the reason (if any) for such termination, and/or
the consequences thereof under the terms of the Plan or any statement evidencing
the grant of an Incentive Award pursuant to the Plan shall be determined by the
Committee's and the Committee's determination thereof shall be final and
binding.
 
8.4    COMPLIANCE WITH GOVERNMENT REGULATIONS
 
       No shares of Common Stock will be issued pursuant to an Incentive Award
unless and until all applicable requirements imposed by federal and state
securities and other laws, rules and regulations and by any regulatory agencies
having jurisdiction and by any stock exchanges upon which the Common Stock may
be listed have been fully met. As a condition precedent to the issuance of
shares of Common Stock pursuant to an Incentive Award, the Company may require
the Participant to take any reasonable action to comply with such requirements.
 
8.5    ADDITIONAL CONDITIONS
 
       The award of any benefit under this Plan may also be subject to such
other provisions (whether or not applicable to the benefit award to any other
Participant) as the Committee determines appropriate including, without
limitation, provisions to assist the Participant in financing the purchase of
Common Stock through the exercise of Stock Options, provisions for the
forfeiture of or restrictions on resale or other disposition of shares of Common
Stock acquired under any form of benefit, provisions giving the Company the
right to repurchase shares of Common Stock acquired under any form of benefit in
the event the Participant elects to dispose of such shares, and provisions to
comply with federal and state securities laws and federal and state income tax
withholding requirements.

8.6    PRIVILEGES OF STOCK OWNERSHIP
 
       No Participant and no beneficiary or other person claiming under or
through such Participant will have any right, title or interest in or to any
shares of Common Stock allocated or reserved under the Plan or subject to any
Incentive Award, except as to such shares of Common Stock, if any, that have
been issued to such Participant in accordance with the terms and conditions of
the applicable Incentive Award; provided, however, that Participants who have
received Restricted Stock shall have only those rights with respect to such
stock as are set forth in this Plan and the statement evidencing the grant or
sale of such Restricted Stock.
 
8.7    AMENDMENT AND TERMINATION OF PLAN: AMENDMENT OF INCENTIVE AWARDS
 
       (a) The Board may alter, amend, suspend or terminate the Plan at any
time. No such action of the Board, unless taken with the approval of the
stockholders of the Company, may increase the maximum number of shares that may
be sold or issued under the Plan or alter the class of Employees eligible to
participate in the Plan. With respect to any other amendments of the Plan, the
Board may in its discretion determine that such amendments shall only become
effective upon approval by the stockholders of the Company, if the Board
determines that such stockholder approval may be advisable, such as for the
purpose of obtaining or retaining any statutory or regulatory benefits under
federal or state securities law, federal or state tax law or any other laws or
for the purposes of satisfying applicable stock exchange listing requirements.
 
       (b) The Committee may, with the consent of a Participant, make such
modifications in the terms and conditions of an Incentive Award as it deems
advisable. Without limiting the generality of the foregoing, the Committee may,
with the consent of the Participant, from time to time to adjust or reduce the
purchase price of Options held by such Participant by cancellation of such
Options and granting of Options to purchase the same or a lesser number of
shares at lower purchase prices or by modification, extension or renewal of such
Options.
 
       (c) Except as otherwise provided in this Plan or in the statement
evidencing the grant of the Incentive Award, no amendment, suspension or
termination of the Plan will, without the consent of the Participant, alter,
terminate, impair or adversely affect any right or obligation under any
Incentive Award previously granted under the Plan.
 
8.8    OTHER COMPENSATION PLANS
 
       The adoption of the Plan shall not affect any other stock option,
incentive or other compensation plans in effect for the Company, nor shall the
Plan preclude the Company from establishing any other forms of incentive or
other compensation for Employees of the Company.
 
8.9    PLAN BINDING ON SUCCESSORS
 
       The Plan shall be binding upon the successors and assigns of the Company.

IX.  EFFECTIVE DATE AND DURATION OF PLAN
 
       The Plan shall become effective on the later of (a) the date of its
adoption by the Board, (b) the date of its approval by the holders of the
outstanding shares of Common Stock (either by a vote of a majority of such
outstanding shares present in person or by proxy and entitled to vote at a
meeting of stockholders of the Company or by written consent) or (c) the date of
the distribution by SKB (as defined in Section 3.6 above) of the stock of
Allergan pursuant to the terms of the Distribution Agreement (as defined in
Section 3.6 above). The Plan shall terminate at such time as the Board, in its
discretion, shall determine. No Incentive Award may be granted under the Plan
after the date of such termination, but such termination shall not affect any
Incentive Award theretofore granted.
