SECTION 1. ESTABLISHMENT AND PURPOSE.

     The purpose of the Plan is to offer selected individuals an opportunity to acquire a
proprietary interest in the success of the Company, or to increase such interest, by exercising
Options to purchase Shares. Options granted under the Plan may include Nonstatutory Options as well
as ISOs intended to qualify under Section 422 of the U. S. Tax Code.

     Capitalized terms are defined in Section 12 hereof.

SECTION 2. ADMINISTRATION.

     (a) Committees of the Board of Directors.

     The Board of Directors shall administer the Plan unless and until the Board of Directors
delegates administration to a Committee, as provided herein. The Board of Directors may delegate
administration of the Plan to one or more Committees consisting of two or more members of the Board
of Directors. If administration is delegated to a Committee, the Committee shall have, in
connection with the administration of the Plan, the powers theretofore possessed by the Board of
Directors, including the power to delegate to a subcommittee any of the administrative powers the
Committee is authorized to exercise, subject, however, to such resolutions, not inconsistent with
the provisions of the Plan, as may be adopted from time to time by the Board of Directors. The
Board of Directors may abolish the Committee at any time and revest in the Board of Directors the
administration of the Plan. Any reference to the Board of Directors in the Plan shall be construed
as a reference to the Committee (if any) to whom the Board of Directors has assigned a particular
function.

     (b) Committee Composition under Section 16 and Section 162(m)

     At such time as the Company is subject to Section 162(m) of the U.S. Tax Code or an Optionee
is subject to Section 16 of the U.S. Exchange Act, in the discretion of the Board of Directors, a
Committee may consist solely of two or more Outside Directors, in accordance with Section 162(m) of
the U.S. Tax Code, and/or two or more Non-Employee Directors, in accordance with Rule 16b-3.
Notwithstanding the foregoing, the Board of Directors or the Committee may (1) delegate to a
committee of one or more members of the Board of Directors who are not Outside Directors the
authority to grant Options to eligible persons who are either (a) not then Covered

1

Table of Contents

Employees and are not expected to be Covered Employees at the time of recognition of income
resulting from such Option or (b) not persons with respect to whom the Company wishes to comply
with Section 162(m) of the U.S. Tax Code and/or (2) delegate to a committee of one or more members
of the Board of Directors who are not Non-Employee Directors the authority to grant Options to
eligible persons who are not then subject to Section 16 of the U.S. Exchange Act.

     (c) Authority of the Board of Directors.

     Subject to the provisions of the Plan, the Board of Directors shall have full authority and
discretion to take any actions it deems necessary or advisable for the administration of the Plan,
including, without limitation, to (i) select Optionees from the individuals eligible to receive
Options under the Plan; (ii) grant Options in accordance with the terms of the Plan; (iii)
determine the terms and conditions of each Option; (iv) specify and approve the provisions of the
Share Option Agreements, including, without limitation, the vesting schedule (if any), the method
of exercise and delivery of notice thereof, including via written or electronic media, in
connection with their Options; (v) construe and interpret any Share Option Agreement delivered
under the Plan; (vi) prescribe, amend and rescind rules and procedures relating to the Plan; (vii)
employ such legal counsel, independent auditors and consultants as it deems desirable for the
administration of the Plan and to rely upon any opinion received therefrom; (viii) vary the terms
of Options to take account of tax, securities law and other regulatory requirements of foreign
jurisdictions; (ix) make all legal and factual determinations; and (x) make all other
determinations and take any other action desirable or necessary to interpret, construe or implement
properly the provisions of the Plan or any Share Option Agreement.

     All decisions, interpretations and other actions of the Board of Directors shall be final and
binding on all Optionees and all persons deriving their rights from an Optionee.

     (d) Governing Law.

     The Plan shall be construed in accordance with the laws of the Republic of Singapore.

SECTION 3. ELIGIBILITY.

     (a) General Rule.

     Employees, Directors and Consultants shall be eligible for the grant of Options except as
follows:

     (i) Employees of Affiliated Companies, Directors who are not Employees and
Consultants shall not be eligible for the grant of ISOs; and

     (ii) Employees, Directors and Consultants, in each case, of Affiliated
Companies who are residents of the United States shall not be eligible for the grant
of Options.

     (b) Ten Percent Shareholders.

     An individual who owns more than 10% of the total combined voting power of all classes of
outstanding shares of the Company, its Parent or any of its Subsidiaries shall not be eligible to
be granted ISOs unless (i) the Exercise Price of the ISO is at least 110% of the Fair Market Value
of a Share on the date of grant and (ii) such ISO by its terms is not exercisable after the
expiration of five years from the date of grant. For purposes of this Subsection (b), in
determining share ownership, the attribution rules of Section 424(d) of the U.S. Tax Code shall be
applied.

Table of Contents

     (c) Section 162(m) Limitation.

     Subject to the provisions of Section 7 relating to adjustment upon change in the Shares, no
Employee shall be eligible to be granted an Option covering more than fifty million (50,000,000)
Shares during any calendar year. This Section 3(c) shall not apply at such times that the Company
is not subject to Section 162(m) of the U.S. Tax Code or such other date required by Section 162(m)
of the U.S. Tax Code and the rules and regulations promulgated thereunder.

SECTION 4. SHARES SUBJECT TO PLAN.

     (a) Basic Limitation.

     Shares offered under the Plan may be unissued Shares or existing Shares (which may include,
where desired, any Shares held by the Company in treasury). Subject to the Companies Act, Chapter
50 of Singapore, the Company shall have the flexibility to deliver Shares to the Optionees by way
of an allotment of new Shares and/or the transfer of existing Shares, including any Shares held by
the Company in treasury. Subject to adjustment as provided pursuant to Section 7 hereof, the
maximum aggregate number of Shares that may be issued or transferred under this Plan shall not
exceed (i) 118 million Shares, plus (ii) any unissued Shares subject to any option or other awards
or rights under the Existing Plans that expire unexercised or are otherwise cancelled as a result
of a termination of those options or other awards or rights under the Existing Plans or the
non-issuance of options or other awards or rights under the Existing Plans. The aggregate number of
Shares that are subject to Options outstanding at any time under the Plan shall not exceed the
number of Shares that then remain available for issuance or transfer. The Company, during the term
of the Plan, shall at all times reserve and keep available sufficient Shares to satisfy the
requirements of the Plan.

     (b) Additional Shares.

     For purposes of determining the number of Shares that remain available for issuance or
transfer under Section 4(a) hereof, the following Shares shall be added back to the Plan Limit and
again be available for the purposes of the Plan and all other share incentive and option schemes
approved by the Board of Directors and contracts of employment:

     (i) The number of Shares tendered in accordance with applicable laws to pay the
exercise price of an Option;

     (ii) The number of Shares acquired by the Company under Section 6(b) below in
satisfaction of any tax withholding requirement; and

     (iii) The number of Shares subject to an Option that expire unexercised or that
are cancelled or otherwise terminated.

SECTION 5. TERMS AND CONDITIONS OF OPTIONS.

     (a) Share Option Agreement.

     Each grant of an Option under the Plan shall be evidenced by a Share Option Agreement between
the Optionee and the Company. Such Option shall be subject to all applicable terms and conditions
of the Plan and may be subject to any other terms and conditions which are not inconsistent with
the Plan and which the Board of Directors deems appropriate for inclusion in a Share Option
Agreement. The provisions of the various Share Option Agreements entered into under the Plan need
not be identical.

Table of Contents

     (b) Number of Shares.

     Each Share Option Agreement shall specify the number of Shares that are subject to the Option
and shall provide for the adjustment of such number in accordance with Section 7. The Share Option
Agreement shall also specify whether the Option is an ISO or a Nonstatutory Option.

     (c) Exercise Price.

     Each Share Option Agreement shall specify the Exercise Price. The Exercise Price of an ISO
shall not be less than 100% of the Fair Market Value of a Share on the date of grant, and a higher
percentage may be required by Section 3(b) hereof. In no event shall the Exercise Price of an
Option be less than the par value (if any) of a Share on the date of grant. Subject to the
preceding two sentences, the Exercise Price under any Option shall be determined by the Board of
Directors at its sole discretion. The Exercise Price shall be payable in a form described in
Section 6 hereof.

     (d) Expenses and Withholding Taxes.

     As a condition to the exercise of an Option, the Optionee shall make such arrangements as the
Board of Directors may require for the satisfaction of any withholding tax obligations and such
other bank-related transactional costs that may arise in connection with such Option exercise or
both of the foregoing. The Board of Directors may require any Optionee to remit to the Company,
prior to exercise of an Option, an amount sufficient to satisfy any applicable tax withholding
requirements or such other bank-related transactional costs associated with the Option exercise or
both of the foregoing. The Board of Directors may permit such Optionee to satisfy, in whole or in
part, such obligations to remit the tax withholdings, pay the bank-related transactional costs
associated with the Option exercise or both of the foregoing by directing the Company to withhold
Shares that would otherwise be received by such Optionee to satisfy the minimum statutory
withholding rates for any applicable tax withholding purposes, any bank-related transactional costs
associated with the Option exercise or both of the foregoing, as applicable, in accordance with all
applicable laws and pursuant to such rules as the Board of Directors may establish from time to
time. The Company shall also have the right to deduct from all cash payments made to an Optionee
(whether or not such payment is made in connection with the exercise of an Option) any applicable
taxes required to be withheld with respect to such payments, or any bank-related transactional
costs associated with the exercise of an Option, in accordance with all applicable laws.

     (e) Exercisability.

     Each Share Option Agreement shall specify the date when all or any installment of the Option
is to become exercisable. The exercisability provisions of any Share Option Agreement shall be
determined by the Board of Directors at its sole discretion.

     (f) Change of Control.

     In the event of a Change of Control, in addition to any action required or authorized by the
terms of a Share Option Agreement, the Board of Directors may, in its sole discretion unless
otherwise provided in a Share Option Agreement, take any or all or any combination of the following
actions as a result, or in anticipation, of any such event:

     (i) accelerate the time period for purposes of vesting in, or realizing gain
from, any outstanding Option made pursuant to this Plan;

     (ii) provide for the continuation of any outstanding Options by the Company (if
the Company is the survivor corporation);

4

Table of Contents

     (iii) provide for the assumption of outstanding Options by the surviving
corporation or its parent;

     (iv) provide for the substitution by the surviving corporation or its parent of
options with substantially the same terms as outstanding Options;

     (v) cancel each outstanding Option but only after payment to the Optionee of an
amount in cash or cash equivalents equal to (A) the Fair Market Value of the Shares
subject to such Option at the time of the merger or consolidation minus (B) the
Exercise Price of the Shares subject to such Option; or

     (vi) make adjustments or modifications to outstanding Options as the Board of
Directors deems appropriate to maintain and protect the rights and interests of
Optionees following the Change of Control.

     Any such action approved by the Board of Directors shall be conclusive and binding on the
Company and all Optionees.

     (g) Basic Term.

     Subject to this Section 5(g), the Share Option Agreement shall specify the term of the Option.
The term of an Option granted to an Employee shall not exceed 7 years from the date of grant, and a
shorter term may be required by Section 3(b) hereof. The term of an Option granted to a person who
is not an Employee shall not exceed 5 years from the date of grant. Subject to the preceding two
sentences, the Board of Directors at its sole discretion shall determine when an Option is to
expire.

     (h) Nontransferability.

     No Option shall be transferable by the Optionee other than to an Optionee’s personal
representative on the death of that Optionee. An Option may be exercised during the lifetime of the
Optionee only by the Optionee or by the Optionee’s guardian or legal representative or such other
person who has the management of the Optionee’s estate. No Option or interest therein may be
transferred, assigned, pledged or hypothecated by the Optionee or by the Optionee’s guardian or
legal representative or such person who has the management of the Optionee’s estate, or during the
Optionee’s lifetime, whether by operation of law or otherwise, or be made subject to execution,
attachment or similar process.

     (i) Termination of Service (Except by Death).

     If an Optionee’s Service terminates for any reason other than the Optionee’s death, then the
Optionee’s Options shall expire on the earliest of the following occasions:

     (i) The expiration date determined pursuant to Subsection (g) above;

     (ii) The date 30 days after the termination of the Optionee’s Service for any
reason other than Disability, or such later date as the Board of Directors may
determine; or

     (iii) The date 12 months after the termination of the Optionee’s Service by
reason of Disability, or such later date as the Board of Directors may determine.

The Optionee or his guardian or legal representative or such other person who has the management of
the Optionee’s estate may exercise all or part of the Optionee’s Options at any time before the
expiration of such Options under the preceding sentence but only to the extent that such Options
had become exercisable before the Optionee’s Service terminated (or became exercisable as a result
of the

5

Table of Contents

termination) unless otherwise determined by the Board of Directors in its sole discretion. The
balance of such Options shall lapse when the Optionee’s Service terminates. In the event that the
Optionee dies after the termination of the Optionee’s Service but before the expiration of the
Optionee’s Options, all or part of such Options may be exercised (prior to expiration) by the
Optionee’s personal representatives, but only to the extent that such Options had become
exercisable before the Optionee’s Service terminated (or became exercisable as a result of the
termination).

     (j) Leave of Absence.

     For purposes of Subsection (i) above, Service shall be deemed to continue while the Optionee
is on a bona fide leave of absence, if such leave was approved by the Company in writing and if
continued crediting of Service for this purpose is expressly required by the terms of such leave or
by applicable law (as determined by the Company).

     (k) Death of Optionee.

     If an Optionee dies while the Optionee is in Service, then the Optionee’s Options shall expire
on the earlier of the following dates:

     (i) The expiration date determined pursuant to Section 5(g) hereof; or

     (ii) The date 12 months after the Optionee’s death or such later date as the
Board of Directors may determine.

All or part of the Optionee’s Options may be exercised at any time before the expiration of such
Options under the preceding sentence by the Optionee’s personal representatives, but only to the
extent that such Options had become exercisable before the Optionee’s death or became exercisable
as a result of the death unless otherwise determined by the Board of Directors in its sole
discretion. The balance of such Options shall lapse when the Optionee dies.

     (l) No Rights as a Shareholder.

     An Optionee, or his guardian, legal representative or such other person who has the management
of the Optionee’s estate, or the personal representatives of an Optionee in the event of the death
of an Optionee, shall have no rights as a shareholder with respect to any Shares covered by the
Optionee’s Option until such person has been allotted and issued or transferred such Shares by
filing a notice of exercise and paying the Exercise Price pursuant to the terms of such Option.

     (m) Modification, Extension and Assumption of Options.

     Within the limitations of the Plan, the Board of Directors may modify, extend or assume
outstanding Options or may accept the cancellation of outstanding Options (whether granted by the
Company or another issuer) in return for the grant of new Options for the same or a different
number of Shares and at the same or a different Exercise Price, provided that such modifications
are permissible under applicable securities laws and the regulations of any exchange or other
securities market on which the Company’s Shares may then be traded. The foregoing notwithstanding,
no modification of an Option shall, without the consent of the Optionee, impair the Optionee’s
rights or increase the Optionee’s obligations under such Option.

     (n) Vesting.

     The Options shall vest in accordance with a schedule determined by the Board of Directors and
set forth in the applicable Share Option Agreement.

Table of Contents

SECTION 6. PAYMENT FOR SHARES

     (a) General Rule.

     The entire Exercise Price of Shares issued or transferred under the Plan shall be payable in
cash or cash equivalents at the time when the Options are exercised, except as otherwise provided
in this Section 6.

     (b) Surrender of Shares.

     To the extent that a Share Option Agreement so provides and provided that the relevant
requirements of the Companies Act, Chapter 50 of Singapore and the requirements of all other
prevailing laws and regulations have been complied with, all or any part of the Exercise Price may
be paid by surrendering Shares that are already owned by the Optionee. Such Shares shall be valued
at their Fair Market Value on the date when the Option is exercised. The Optionee shall not
surrender Shares in payment of the Exercise Price if such action would cause the Company to
recognize compensation expense (or additional compensation expense) with respect to the Option for
financial reporting purposes.

     (c) Exercise/Sale.

     To the extent that a Share Option Agreement so provides, and in accordance with the rules and
procedures established by the Board of Directors for this purpose and subject to applicable law, an
Option may also be exercised through “cashless exercise” procedures approved by the Board of
Directors involving a broker or dealer approved by the Board of Directors that affords an Optionee
the opportunity to sell immediately some or all of the Shares underlying the exercised portion of
the Option in order to generate sufficient cash to pay the Exercise Price and/or to satisfy
withholding tax obligations related to the Option.

     (d) Exercise/Pledge.

     To the extent that a Share Option Agreement so provides, and in accordance with the rules and
procedures established by the Board of Directors for this purpose and subject to applicable law,
payment of the Exercise Price may be made all or in part by the delivery of an irrevocable
direction to pledge Shares to a securities broker or lender approved by the Board of Directors, as
security for a loan, and to deliver sufficient cash to pay the Exercise Price and/or to satisfy
withholding tax obligations related to the Option.

SECTION 7. ADJUSTMENT OF SHARES.

     (a) General.

     In the event of a subdivision of the outstanding Shares, a declaration of a dividend payable
in Shares, a declaration of an extraordinary dividend payable in a form other than Shares in an
amount that has a material effect on the Fair Market Value of the Shares, a consolidation of the
outstanding Shares into a lesser number of Shares, a recapitalization, a reclassification,
reorganization, merger, consolidation, combination or a similar occurrence, the Board of Directors
shall make appropriate adjustments in one or more of (i) the number of Shares available for future
grants under Section 4 hereof, (ii) the number of Shares covered by each outstanding Option or
(iii) the Exercise Price under each outstanding Option.

     (b) Reservation of Rights.

     Except as provided in this Section 7, an Optionee shall have no rights by reason of (i) any
subdivision or consolidation of shares of any class, (ii) the payment of any dividend or (iii) any

7

Table of Contents

other increase or decrease in the number of shares of any class. Any issuance by the Company
of shares of any class, or securities convertible into shares of any class, shall not affect, and
no adjustment by reason thereof shall be made with respect to, the number or Exercise Price of
Shares subject to an Option. The grant of an Option pursuant to the Plan shall not affect in any
way the right or power of the Company to make adjustments, reclassifications, reorganizations or
changes of its capital or business structure, to merge or consolidate or to dissolve, liquidate,
sell or transfer all or any part of its business or assets.

SECTION 8. SECURITIES LAW REQUIREMENTS.

STATS ChipPAC LTD.

PERFORMANCE SHARE PLAN

SECTION 1. ESTABLISHMENT AND PURPOSE.

     The purpose of the Plan is to offer selected individuals an opportunity to acquire a
proprietary interest in the success of the Company, or to increase such interest, through the grant
of Performance Shares.

     Capitalized terms are defined in Section 12 hereof.

SECTION 2. ADMINISTRATION.

     (a) Committees of the Board of Directors.

     The Board of Directors shall administer the Plan unless and until the Board of Directors
delegates administration to a Committee, as provided herein. The Board of Directors may delegate
administration of the Plan to one or more Committees consisting of two or more members of the Board
of Directors. If administration is delegated to a Committee, the Committee shall have, in
connection with the administration of the Plan, the powers theretofore possessed by the Board of
Directors, including the power to delegate to a subcommittee any of the administrative powers the
Committee is authorized to exercise, subject, however, to such resolutions, not inconsistent with
the provisions of the Plan, as may be adopted from time to time by the Board of Directors. The
Board of Directors may abolish the Committee at any time and revest in the Board of Directors the
administration of the Plan. Any reference to the Board of Directors in the Plan shall be construed
as a reference to the Committee (if any) to whom the Board of Directors has assigned a particular
function.

     (b) Committee Composition under Section 16 

     At such time as a Grantee is subject to Section 16 of the U.S. Exchange Act, in the discretion
of the Board of Directors, a Committee may consist solely of two or more Non-Employee Directors, in
accordance with Rule 16b-3. Notwithstanding the foregoing, the Board of Directors or the Committee
may delegate to a committee of one or more members of the Board of Directors who are not
Non-Employee Directors the authority to grant Performance Shares to eligible persons who are not
then subject to Section 16 of the U.S. Exchange Act.

     (c) Authority of the Board of Directors.

     Subject to the provisions of the Plan, the Board of Directors shall have full authority and
discretion to take any actions it deems necessary or advisable for the administration of the Plan,
including, without limitation, to (i) select Grantees from the individuals eligible to receive
Performance Shares under the Plan; (ii) grant Performance Shares in accordance with the terms of
the Plan; (iii) determine the terms and conditions of each Performance Share; (iv) specify and
approve the provisions of the Performance Share Agreements, including, without limitation, the
vesting schedule (if any), the effect of termination of employment and the delivery of Shares, in
connection with the Performance Shares; (v) determine that a Performance Share award shall vest or be granted
subject to satisfaction of one or more performance goals; (vi) construe and interpret any
Performance Share Agreement delivered under the Plan; (vii) prescribe, amend and rescind rules and
procedures relating to the Plan; (viii) employ such legal counsel, independent auditors and
consultants as it deems desirable for the administration of the Plan and to rely upon any opinion
received therefrom; (ix) vary the terms of Performance Shares to take account of tax, securities
law and other regulatory requirements of foreign jurisdictions; (x) make all legal and factual
determinations; and (xi) make all other determinations and take any other action desirable or
necessary to interpret, construe or implement properly the provisions of the Plan or any
Performance Share Agreement.

     Performance goals shall be determined by the Board of Directors and will be designed to
support the business strategy, and align Grantee interests with customer and shareholder interests.
For awards that are intended to qualify as performance-based compensation, performance goals
will be based on one or more of the following business criteria: sales or licensing volume,
revenues, customer satisfaction, expenses, organizational health/productivity, earnings (which
includes similar measurements such as net profits, operating profits and net income, and which may
be calculated before or after taxes, interest, depreciation, amortization or taxes), margins, cash
flow, shareholder return, return on equity, return on assets or return on investments, working
capital, product shipments or releases, brand or product recognition or acceptance and/or share
price. These criteria may be measured: individually, alternatively or in any combination; with
respect to the Company, a subsidiary, division, business unit, product line, product or any
combination of the foregoing; on an absolute basis, or relative to a target, to a designated
comparison group, to results in other periods or to other external measures; and including or

1

 

excluding items that could affect the measurement, such as extraordinary or unusual and
nonrecurring gains or losses, litigation or claim judgments or settlements, material changes in tax
laws, acquisitions or divestitures, the cumulative effect of accounting changes, asset write-downs,
restructuring charges, or the results of discontinued operations.

     All decisions, interpretations and other actions of the Board of Directors shall be final and
binding on all Grantees and all persons deriving their rights from a Grantee.

     (d) Governing Law.

     The Plan shall be construed in accordance with the laws of the Republic of Singapore.

SECTION 3. ELIGIBILITY.

     Generally, Employees, Directors and Consultants shall be eligible for the grant of Performance
Shares; however, such grants will typically be made only to employees who report directly to the
Company’s Chief Executive Officer.

SECTION 4. SHARES SUBJECT TO PLAN.

     (a) Basic Limitation.

     Shares offered under the Plan may be unissued Shares or existing Shares (which may include,
where desired, any Shares held by the Company in treasury). Subject to the Companies Act, Chapter
50 of Singapore, the Company shall have the flexibility to deliver Shares to the Grantees by way of
an allotment of new Shares and/or the transfer of existing Shares, including any Shares held by the
Company in treasury. Subject to adjustment as provided pursuant to Section 7 hereof, the maximum
aggregate number of Shares that may be issued or transferred under this Plan shall not exceed 15
million Shares. The aggregate number of Shares that are subject to Performance Shares outstanding
at any time under the Plan shall not exceed the number of Shares that then remain available for
issuance or transfer. The Company, during the term of the Plan, shall at all times reserve and
keep available sufficient Shares to satisfy the requirements of the Plan.

     (b) Additional Shares.

     For purposes of determining the number of Shares that remain available for issuance or
transfer under Section 4(a) hereof, the following Shares shall be added back to the Plan Limit and
again be available for the purposes of the Plan and all other share incentive and option schemes
approved by the Board of Directors and contracts of employment:

     (i) The number of Shares acquired by the Company under Section 6(b) below in satisfaction of
any tax withholding requirement; and

     (ii) The number of Shares subject to a grant of Performance Shares that is cancelled or
otherwise terminated.

SECTION 5. TERMS AND CONDITIONS OF PERFORMANCE SHARES.

     (a) Grant.

     Subject to the provisions of the Plan, the Board of Directors or the Committee (if one is
appointed) shall have sole and complete authority to determine to whom Performance Shares shall be
granted, the number of Performance Shares to be granted to each Grantee, the duration of the period
during which, and the conditions under which, the Performance Shares may be forfeited to the
Company, and the other terms and conditions of the Performance Shares. In the event that the Board
of Directors or the Committee determines to impose performance goals (as described in Section 2(c)
above), such goals will be determined and achieved during a performance period which shall conclude
before any grant is made or communicated to Grantees.

     (b) Payment.

     Performance Shares may be paid in cash or shares, as determined in the sole discretion of the
Board of Directors or the Committee (if one is appointed), upon satisfaction of the applicable
terms and conditions as set forth in the Performance Share Agreement. In any event payment made
pursuant to the Performance Shares will be made no later than the later of (i) the 15th
day of the third month following participant’s taxable year in which the Performance Shares vest
(March 15) or (ii) the 15th day of the third month following the Company’s taxable year
in which the Performance Shares vest.

2

 

     (c) Performance Share Agreement.

     Each grant of Performance Shares under the Plan shall be evidenced by a Performance Share
Agreement between the Grantee and the Company. Such grant of Performance Shares shall be subject to
all applicable terms and conditions of the Plan and may be subject to any other terms and
conditions which are not inconsistent with the Plan and which the Board of Directors deems
appropriate for inclusion in a grant of Performance Share Agreement. The provisions of the various
grant of Performance Share Agreements entered into under the Plan need not be identical.

     (d) Number of Shares.

     Each Performance Share Agreement shall specify the number of Shares that are subject to the
grant and shall provide for the adjustment of such number in accordance with Section 7.

     (e) Expenses and Withholding Taxes.

     As a condition to the issuance or transfer of Shares, the Grantee shall make such arrangements
as the Board of Directors may require for the satisfaction of any withholding tax obligations and
such other bank-related transactional costs that may arise in connection with the Performance
Shares or both of the foregoing. The Board of Directors may require any Grantee to remit to the
Company, prior to the issuance or transfer of Shares, an amount sufficient to satisfy any
applicable tax withholding requirements or such other bank-related transactional costs associated
with the Performance Shares or both of the foregoing. The Board of Directors may permit such
Grantee to satisfy, in whole or in part, such obligations to remit the tax withholdings, pay the
bank-related transactional costs associated with the Performance Shares or both of the foregoing by
directing the Company to withhold Shares that would otherwise be received by such Grantee to
satisfy the minimum statutory withholding rates for any applicable tax withholding purposes, any
bank-related transactional costs associated with the Performance Shares or both of the foregoing,
as applicable, in accordance with all applicable laws and pursuant to such rules as the Board of
Directors may establish from time to time. The Company shall also have the right to deduct from all
cash payments made to a Grantee (whether or not such payment is made in connection with the
Performance Shares) any applicable taxes required to be withheld with respect to such payments, or
any bank-related transactional costs associated with the Performance Shares, in accordance with all
applicable laws.

     (f) Change of Control.

     In the event of a Change of Control, in addition to any action required or authorized by the
terms of a Performance Share Agreement, the Board of Directors may, in its sole discretion unless
otherwise provided in a Performance Share Agreement, take any or all or any combination of the
following actions as a result, or in anticipation, of any such event:

     (i) accelerate the time period for purposes of realizing gain from, any outstanding
Performance Shares made pursuant to this Plan;

     (ii) provide for the continuation of any outstanding Performance Share awards by the Company
(if the Company is the survivor corporation);

     (iii) provide for the assumption of outstanding Performance Share awards by the surviving
corporation or its parent;

     (iv) provide for the substitution by the surviving corporation or its parent of options with
substantially the same terms as outstanding Performance Share awards;

     (v) cancel each outstanding Performance Share award but only after payment to the Grantee of
an amount in cash or cash equivalents equal to (A) the Fair Market Value of the Shares subject to
such Performance Share award at the time of the merger or consolidation; or

     (vi) make adjustments or modifications to outstanding Performance Share awards as the Board of

receive dividends) with respect to any Shares covered by the Grantee’s Performance Share award
until such Shares have been issued or transferred pursuant to the terms of such Performance Share
award.

amount that has a material effect on the Fair Market Value of the Shares, a consolidation of the
outstanding Shares into a lesser number of Shares, a recapitalization, a reclassification,

employing or retaining the Grantee) or of the Grantee, which rights are hereby expressly reserved
by each, to terminate his or her Service at any time and for any reason, with or without cause.
