respectively.
5.Effective as of January 1, 2011, Section 2.24 is hereby amended by adding
thereto the following Subsection (e):

2

--------------------------------------------------------------------------------

“(e)    An Employee is a Highly Compensated Employee under the Puerto Rico Code
if such Employee performed services for the Company during the Plan Year and
meets one or more of the following criteria:
(i)    such Employee is an officer of the Company at any time during the Plan
Year;
(ii)    such Employee is, at any time during the Plan Year, an owner of more
than 5% of stock with voting rights or of the value of all classes of stock of
the Company. For purposes of this Subsection (ii), the controlled group rules of
Section 1010.04 of the Puerto Rico Code, the affiliated entity rules of Section
1010.05 of the Puerto Rico Code and the affiliated service group rules of
Section 1081.01(a)(14) of the Puerto Rico Code shall be used in computing the
ownership percentage; and
(iii)    such Employee received Compensation during the preceding Plan Year from
the Company in excess of the limit under Code Section 414(q)(1)(B).”
6.Effective as of January 1, 2011, Section 5.12 is hereby amended by adding
thereto the following Subsection (e):
“(e)    Notwithstanding the definition of Compensation contained in subsections
(a), (b), (c) and (d), for the purposes of this Article V and Section 2.24, Plan
Years and Limitation Years (as applicable) beginning on and after January 1,
2011, Compensation shall mean wages within the meaning of Code Section 3401(a)
and all other payments of compensation to an Employee by the Employer (in the
course of the Employer’s trade or business) for which the Employer is required
to furnish the Employee a written statement under Code Sections 6041(d),
6051(a)(3), and 6052. Compensation must be determined without regard to any
rules under Code Section 3401(a) that limit the remuneration included in wages
based on the nature or location of the employment or the services performed
(such as the exception for agricultural labor in Code Section 3401(a)(2)).
Compensation paid or made available during each such Plan Year and Limitation
Year also shall include any elective deferral (as defined in Code Section
402(g)(3) or Puerto Rico Code Section 1081.01(d) or its predecessor Section
1165(e) of the Puerto Rico Internal Revenue Code of 1994), and any amount which
is contributed or deferred by the Employer at the election of the Employee and
which is not includible in the gross income of the Employee by reason of Code
Section 125 or 457. For Plan Years and Limitation Years (as applicable)
beginning on and after January 1, 2011, Compensation as defined in this
paragraph also shall include any elective amounts that are not includible in the
gross income of the employee by reason of Code Section 132(f)(4).”
7.Effective as of January 1, 2012, Section 5.12 is hereby amended by adding
thereto the following Subsection (f):
“(f)    Notwithstanding any provision of the Plan to the contrary, effective

3

--------------------------------------------------------------------------------

January 1, 2012, for purposes of the application of Sections 5.6 and 5.7 to a
Participant who is a resident of Puerto Rico and to whom the Puerto Rico Code is
applicable, Compensation considered under such Sections may not exceed the limit
under Code Section 401(a)(17), as adjusted from time to time. Provided, that the
application of this limitation shall not operate to reduce any benefit accrued
as of December 31, 2011.”
8.Effective as of January 1, 2008, Article 8.4 of the Plan is amended in its
entirety to read as follows:
“8.4    Funding Based Limits on Benefits and Benefit Accruals.
(a)    Effective as of January 1, 2008, notwithstanding any other provision of
the Plan, no benefit shall accrue or be paid under the Plan, and no amendment
increasing liability for benefits shall take effect, to the extent prohibited by
the funding-based limits in Code Section 436 (or any successor provision
thereto) and, effective as of January 1, 2010, the final regulations issued
thereunder (the “Limits”).
(b)    The Limits imposed by Code Section 436 and guidance issued thereunder on
(i) Plan amendments, (ii) accelerated benefit payments, (iii) benefit accruals,
and (iv) unpredictable contingent event benefits are set forth below. The Limits
shall be applied on a Participant by Participant and Beneficiary by Beneficiary
basis.
The Committee shall provide notification to affected Participants and
Beneficiaries, as applicable, in accordance with the requirements of Section
1.436-1(a)(6) of the Treasury Regulations if the Plan becomes subject to the
Limits of Code Sections 436(b), (d), or (e).
Except to the extent required by law or provided in a subsequent amendment to
the Plan, the Plan shall not restore any benefits that did not accrue (by reason
of a cessation of accruals or failure of an amendment to take effect), and shall
not make any payment in lieu of any benefits that are not paid, by reason of the
Limits unless the provisions of Subsection (h) below apply and the Limits are
lifted within the same Plan Year.
This Section 8.4 is intended to comply with the requirements of Code Section 436
and guidance issued thereunder. If there is any discrepancy or ambiguity between
this Section 8.4 and Code Section 436 and applicable guidance, Code Section 436
and such guidance shall control. This Section 8.4 shall not be construed in a
manner that would impose limitations that are more stringent than those required
by Code Section 436 and applicable guidance. If any limitation described in this
Section 8.4 is determined not to be required by Code Section 436 and guidance
issued thereunder, such limitation shall not apply.
(c)    No amendment to the Plan which would increase the Plan’s liabilities by
increasing benefits, establishing new benefits, or changing the rate of benefit
accrual or vesting of benefits shall take effect during a Plan Year if the
Plan’s AFTAP for such Plan Year is less than 80% or would be less than 80% if
the Plan amendment were taken into account. However, this Subsection (c) shall
not apply to any

4

--------------------------------------------------------------------------------

amendment that (i) implements a mandatory change in the vesting requirements
applicable to the Plan under the Code or ERISA, (ii) provides for a benefit
increase under a formula that is not compensation-based and the rate of such
increase does not exceed the contemporaneous increase in average wages for
Participants covered by the amendment (provided that the limit described in
Subsection (d) below does not also apply), or (iii) is excepted under guidance
issued by the Commissioner of Internal Revenue.
If any Plan amendment cannot take effect during the Plan Year in which it would
otherwise have become effective by reason of the limit described in this
Subsection (c), then such amendment, if previously adopted, shall be treated as
if it were never adopted unless the amendment specifically provides otherwise;
provided, however, that if the Plan amendment does not go into effect for a Plan
Year because of the application of a presumed AFTAP determined under Code
Section 436(h) and Section 1.436-1(h) of the Treasury Regulations, then the Plan
amendment must go into effect for the Plan Year if it would be permitted under
the rules of Code Section 436 based on a certified AFTAP for the Plan Year which
takes into account the increase in the funding target attainment percentage
attributable to the Plan amendment, unless the Plan amendment provides
otherwise.
(d)    If the Plan’s AFTAP for a Plan Year is less than 80%, the following
limits on accelerated benefit payments shall apply:
(i)    Subject to Subsection (iii) below, if the Plan’s AFTAP for a Plan Year is
at least 60% but is less than 80%, a Participant or Beneficiary may not elect an
optional benefit form that includes a Prohibited Payment, and the Plan shall not
make a Prohibited Payment, with an Annuity Starting Date on or after the Section
436 Measurement Date as of which the limit described in this Subsection (d)(i)
begins to apply and before the Section 436 Measurement Date as of which it
ceases to apply, unless the present value (determined using the Applicable
Interest Rate and Applicable Mortality Table) of the portion of the benefit that
is being paid in a Prohibited Payment (i.e., the unrestricted portion) does not
exceed the lesser of:
(A)    50% of the present value of the benefit payable in the optional form of
benefit that includes the Prohibited Payment; or
(B)    100% of the present value of the maximum guaranteed benefit applicable to
the Participant under Section 4022 of ERISA for the year in which the Annuity
Starting Date occurs.
For purposes of this paragraph (B), the portion of the benefit that is being
paid in a Prohibited Payment is deemed to be the excess of each payment over the
smallest payment during the Participant’s lifetime under the optional form of
benefit (treating a

5

--------------------------------------------------------------------------------

period after the Annuity Starting Date and during the Participant’s lifetime in
which no payments are made as a payment of zero).
(ii)    If the Plan’s AFTAP for a Plan Year is less than 60%, a Participant or
Beneficiary may not elect an optional benefit form that includes a Prohibited
Payment, and the Plan shall not make a Prohibited Payment, with an Annuity
Starting Date on or after the Section 436 Measurement Date as of which the limit
described in this Subsection (ii) begins to apply and before the Section 436
Measurement Date as of which it ceases to apply.
For any period in which the Plan sponsor is a debtor in a case under Title 11 of
the United States Code, or a similar federal or state law, a Participant or
Beneficiary may not elect an optional benefit form that includes a Prohibited
Payment, and the Plan shall not make a Prohibited Payment, with an Annuity
Starting Date during such period and before the date the actuary for the Plan
certifies that the Plan’s AFTAP is not less than 100%.
(iii)    The following special rules shall apply:
(A)    Only one Prohibited Payment may be made with respect to any Participant
during any period of consecutive Plan Years during which the limits described in
this Subsection (iii) apply.
(B)    If an optional form of benefit that is otherwise available under the Plan
is not available as of an Annuity Starting Date due to the limits described in
this Subsection (iii), the Participant or Beneficiary may elect to bifurcate his
benefit into unrestricted and restricted portions as described in Section
1.436-1(d)(3)(ii) of the Treasury Regulations.
(C)    Participants or beneficiaries shall not be permitted to have a new
Annuity Starting Date for which the form of payment previously elected may be
modified with respect to a period of time during which the limitations of Code
Section 436 cease to apply and benefits shall continue to be paid in the normal
or optional form of payment previously applied or elected after the limits cease
to apply.
(D)    If a Participant or Beneficiary requests a distribution in an optional
form of payment that includes a Prohibited Payment not permitted to be currently
paid, the Participant or Beneficiary retains the right to defer payment until
his Normal Retirement

6

--------------------------------------------------------------------------------

Date or his Later Retirement Date, as applicable, subject to the requirements of
Code Sections 411(a)(11) and 401(a)(9) and regulations thereunder.
(E)    Benefits provided to a Participant and any Beneficiary (including an
Alternate Payee) of such Participant are aggregated as described in Section
1.436-1(d)(3)(iv)(B) of the Treasury Regulations.
(F)    If the limits described in this Subsection (iii) apply as of a Section
436 Measurement Date, but the limits subsequently cease to apply to the Plan as
of a later Section 436 Measurement Date, then the limits shall not apply to
benefits with Annuity Starting Dates that occur on or after that later Section
436 Measurement Date.
(e)    If the Plan’s AFTAP for a Plan Year is less than 60%, all benefit
accruals under the Plan other than interest credits shall cease as of the
applicable Section 436 Measurement Date. During any period that the Plan is
required to cease accruals under this Subsection (e) the Plan may not be amended
to increase Plan liabilities by increasing benefits or providing new benefits.
If the limit described in this Subsection (e), ceases to apply to the Plan, the
limit does not apply to benefit accruals based on service on or after the
Section 436 Measurement Date as of which the limit ceases to apply.
(f)    No Unpredictable Contingent Event Benefit shall be paid with respect to
an unpredictable contingent event occurring during a Plan Year if the Plan’s
AFTAP for the Plan Year is less than 60% or would be less than 60% taking into
account any benefits that could be payable with respect to such event. If any
benefit does not become payable during the Plan Year by reason of the limit
described in this Subsection (f), the Plan is treated as if it does not provide
for such benefit. Notwithstanding the foregoing, if an Unpredictable Contingent
Event Benefit is not paid for a Plan Year because of application of a presumed
AFTAP determined under Code Section 436(h) and Section 1.436-1(h) of the
Treasury Regulations, then the Unpredictable Contingent Event Benefit must be
paid if it would be permitted under the rules of Code Section 436 based on a
certified AFTAP for the Plan Year which takes into account the increase in the
funding target attainment percentage attributable to the Unpredictable
Contingent Event Benefit.
(g)    Any Code Section 436 limitation in effect immediately prior to
termination of the Plan shall continue to apply after such termination, provided
however, that the restriction of Code Section 436(d) shall not apply to a
Prohibited Payment made to carry out the termination of the Plan in accordance
with applicable law.
(h)    The Employer may use any method permitted under Code Section 436 and
guidance issued thereunder to avoid application of any limit described in

7

--------------------------------------------------------------------------------

this Section 8.4, including providing security in the form described in Section
1.436-1(f)(3) of the Treasury Regulations. However, the Employer shall not be
required (i) to make additional contributions, (ii) to provide additional
security to the Plan, or (iii) to alter the method or timing of any actuarial
valuation, in order to avoid the application of the funding-based limits
described in this Section 8.4.
(i)    For purposes of this Section 8.4, the following special definitions shall
apply:
(i)    “AFTAP” means the “adjusted funding target attainment percentage” as
described in Code Section 436(j) and Section 1.436-1(j)(1) of the Treasury
Regulations. Notwithstanding the foregoing, for Plan Years beginning on or after
October 1, 2008 and before October 1, 2010:
(A)    for the purpose of determining if the funding limits would apply to a
payment under a social security leveling option as defined in Code Section
436(j)(3)(C) and in accordance with Section 203 of the Preservation of Access to
Care for Medicare Beneficiaries and Pension Relief Act of 2010 (“PRA 2010”), the
AFTAP shall be determined in accordance with the special rules set forth in Code
Sections 436(j)(3)(A) and (B) and in accordance with PRA 2010 Section 203; and
(B)    for the purpose of determining if the Plan’s AFTAP for a Plan Year is
less than 60%, the AFTAP shall be determined in accordance with the special
rules set forth in Code Sections 436(j)(3)(A) and (B) and in accordance with
Section 203 of the Worker, Retiree, and Employer Recovery Act of 2008 which
shall apply only to the extent that such Section produces a higher AFTAP for the
Plan Year than under Code Sections 436(j)(3)(A) and (B).
(ii)    “Annuity Starting Date” means the “annuity starting date” as defined in
Section 1.436-1(j)(2) of the Treasury Regulations.
(iii)    “Prohibited Payment” means a “prohibited payment” as defined in Code
Section 436(d)(5) and Section 1.436-1(j)(6) of the Treasury Regulations and
generally includes: (A) any payment in excess of the monthly amount paid under a
life annuity (plus any social security supplement described in the last sentence
of Code Section 411(a)(9)), to a Participant or Beneficiary whose Annuity
Starting Date occurs during any period in which a limitation under Subsection
(d) above is in effect; (B) any payment for the purchase of an irrevocable
commitment from an insurer to pay

8

--------------------------------------------------------------------------------

benefits; (C) any transfer of assets and liabilities to another plan maintained
by the Employer or an Affiliated Company that is made in order to avoid or
terminate application of the limitations described in this Section 8.4, and (D)
any other payment specified by the Secretary of the Treasury. However, such term
shall not include a payment that may be immediately distributed without consent
pursuant to Code Section 411(a)(11).
(iv)    “Section 436 Measurement Date” means the “section 436 measurement date”
as defined in Section 1.436-1(j)(8) of the Treasury Regulations that is used to
determine when the limitations described in this Section 8.4 apply or cease to
apply.
(v)    “Unpredictable Contingent Event Benefit” means an “unpredictable
contingent event benefit” as defined in Code Section 436(b)(3) and Section
1.436-1(j)(9) of the Treasury Regulations.”
9.Effective as of January 1, 2012, Section 12.7 is hereby amended by adding the
following sentence at the end thereof:
“The rules of this Article XII shall not apply to a Participant who is a
resident of Puerto Rico unless such exclusion is impermissible under the Code,
in which case the application of the rules of Article XII to a Participant who
is a resident of Puerto Rico shall not cause the Participant’s maximum
permissible benefit to exceed the limits of Section 5.7.”
IN WITNESS WHEREOF, the Company has caused this First Amendment to the Allergan,
Inc. Pension Plan (Restated January 1, 2011) to be executed by its duly
authorized officer on this 21 day of December, 2011.
