1. PURPOSE.

     This McKesson Corporation 2005 Stock Plan is intended to provide Employees and Directors the
opportunity to receive equity-based, long-term incentives so that the Corporation may effectively
attract and retain the best available personnel, promote the success of the Corporation by
motivating Employees and Directors to superior performance, and align Employee and Director
interests with those of the Corporation’s stockholders.

2. EFFECTIVE DATE.

     This Plan was initially adopted by the Board on May 25, 2005, subject to stockholder approval,
which was granted on July 27, 2005. On October 27, 2006, the Board retroactively amended and
restated the Plan to comply with proposed regulations issued under Code section 409A. On May 23,
2007, the Plan was amended by the Board to increase the share reserve by 15,000,000 Shares, with
such amendment subject to stockholder approval, which was granted on July 25, 2007. On July 23,
2008, the Board approved an amendment and restatement of the Plan regarding the timing of the
distribution of Shares underlying grants of Restricted Stock Unit Awards to Outside Directors. On
May 26, 2009, the Compensation Committee approved an amendment of the Plan regarding the
circumstances under which a merger or consolidation involving the Corporation would constitute a
Change in Control. On May 27, 2009, the Board amended and restated the Plan to increase the share
reserve by 14,500,000 Shares, with such amendment and restatement subject to stockholder approval,
which was granted on July 22, 2009. On April 20, 2010, the Compensation Committee amended and
restated the Plan to incorporate by reference the Company’s Compensation Recoupment Policy, which
was first adopted on January 20, 2010, as amended from time to time. On April 21, 2010, the Board
amended and restated the Plan to add performance criteria to which performance-based grants may be
subject, subject to stockholder approval, which was granted and the amended and restated Plan
became effective on July 28, 2010.

3. ADMINISTRATION.

     (a) Administration with respect to Outside Directors.

     With respect to Awards to Outside Directors, the Plan shall be administered by (A) the Board
or (B) the Governance Committee; provided that such committee consists solely of Directors who
qualify as “non-employee directors” for purposes of Rule 16b-3 promulgated under the Exchange Act.
Notwithstanding the foregoing, all Awards made to members of the Governance Committee shall be
approved by the Board.

     (b) Administration with respect to Employees.

     With respect to Awards to Employees, the Plan shall be administered by (A) the Board, (B) the
Compensation Committee; provided that such committee consists solely of Directors who qualify as
“outside directors” for purposes of Code section 162(m) and “non-employee directors” for purposes
of Rule 16b-3 promulgated under the Exchange

1

 

Act, or (C) in limited situations, by an officer or officers of Corporation pursuant to
Section 3(c) below.

     (c) Delegation of Authority to an Officer of the Corporation.

          (i) The Board may delegate to a Director the authority to administer the Plan with respect to
Awards made to Employees who are not subject to Section 16 of the Exchange Act.

          (ii) The Board may delegate to an officer or officers of the Corporation the authority to
administer the Plan with respect to Options granted to Employees who are not subject to Section 16
of the Exchange Act.

     (d) Powers of the Administrator.

     The Administrator shall from time to time at its discretion make determinations with respect
to Employees and Directors who shall be granted Awards, the number of Shares or Share Equivalents
to be subject to each Award, the vesting of Awards, the designation of Options as Incentive Stock
Options or Nonstatutory Stock Options and other conditions of Awards to Employees and Directors.

     The Administrator shall have the full power and authority, in its sole discretion, to
promulgate any rules and regulations which it deems necessary for the proper administration of the
Plan, to supervise the administration of the Plan, to make factual determinations relevant to Plan
entitlements, to adopt subplans applicable to specified Affiliates or locations and to take all
actions in connection with the administration of the Plan as it deems necessary or advisable.

     The Administrator shall have, subject to the terms and conditions and within the limitations
of Plan, including the limitations of Section 22, the authority to modify, extend or renew
outstanding Awards granted to Employees and Directors under the Plan in a manner that will not
cause the Awards that are exempt from the application of Code section 409A to be subject to Code
section 409A pursuant to such modification, extension or renewal. Notwithstanding the foregoing,
however, no modification of an Award shall, without the consent of the Participant, impair any
Award previously granted under the Plan.

     The interpretation and construction by the Administrator of any provisions of the Plan or of
any Award shall be final. No member of a Committee shall be liable for any action or determination
made in good faith with respect to the Plan or any Award.

4. ELIGIBILITY.

     Subject to the terms and conditions set forth below, Awards may be granted to Employees and
Directors. Notwithstanding the foregoing, only employees of the Corporation and its Subsidiaries
may be granted Incentive Stock Options.

2

 

     (a) Ten Percent Stockholders.

     An Employee who owns more than 10% of the total combined voting power of all classes of
outstanding stock of the Corporation, its parent or any of its Subsidiaries is not eligible to
receive an Incentive Stock Option pursuant to this Plan unless the Exercise Price of the Incentive
Stock Option is at least 110% of the Fair Market Value of the underlying Shares on the date of the
grant and the term of the option does not exceed five years. For purposes of this Section 4(a) the
stock ownership of an Employee shall be determined pursuant to Code section 424(d).

     (b) Number of Awards.

     A Participant may receive more than one Award, including Awards of the same type, but only on
the terms and subject to the restrictions set forth in the Plan. Subject to adjustment as provided
in Section 16, the maximum aggregate number of Shares or Share Equivalents that may be subject to
Full Value Awards granted to a Participant in any fiscal year of the Corporation is 500,000 Shares
or Share Equivalents and the maximum number of Shares or Share Equivalents that may be subject to
Options or Stock Appreciation Rights granted to a Participant in any fiscal year of the Corporation
is 1,000,000 Shares or Share Equivalents.

5. STOCK.

     (a) Share Reserve.

     Subject to adjustment as provided in Section 16, the aggregate number of Shares subject to
Options, Stock Appreciation Rights, Restricted Stock, Restricted Stock Units, Performance Shares or
Other Share-Based Awards issued under this Plan shall not exceed 42,500,000 Shares, which Shares
shall be Shares of the Corporation’s authorized but unissued or reacquired Common Stock bought on
the market or otherwise. If any outstanding Option or Stock Appreciation Right under the Plan for
any reason expires or is terminated or any Restricted Stock or Other Share-Based Award is
forfeited, then the Shares allocable to the unexercised portion of such Option or Stock
Appreciation Right or the forfeited Restricted Stock or Other Share-Based Award may again be
available for issuance under the Plan. The following Shares may not again be made available for
issuance under the Plan: Shares not issued or delivered as a result of the net exercise of a Stock
Appreciation Right or Option; Shares used to pay the withholding taxes related to an Award; or
Shares repurchased on the open market with the proceeds of an Exercise Price.

     (b) Limitation.

     Notwithstanding any other provision of Section 5, for any one Share issued in connection with
a Full Value Award or a stock-settled Stock Appreciation Right, that Share and one additional Share
shall no longer be available for issuance in connection with future Awards.

3

 

6. OPTIONS.

     Options granted to Employees and Directors pursuant to the Plan shall be evidenced by written
Option Agreements in such form as the Administrator shall determine. Options shall be designated
as Incentive Stock Options or Nonstatutory Stock Options and shall be subject to the following
terms and conditions:

     (a) Number of Shares.

     Each Option shall state the number of Shares to which it pertains, which shall be subject to
adjustment in accordance with Section 16.

     (b) Exercise Price.

     Each Option shall state the Exercise Price, determined by the Administrator, which shall not
be less than 100% the Fair Market Value of a Share on the date of grant, except as provided in
Section 16.

     (c) Method of Payment.

     An Option may be exercised, in whole or in part, by giving notice of exercise in the manner
prescribed by the Corporation specifying the number of Shares to be purchased. Such notice shall
be accompanied by payment in full of the Exercise Price in cash or, if acceptable to the
Administrator in its sole discretion (i) in Shares already owned by the Participant (including,
without limitation, by attestation to the ownership of such Shares), (ii) by the withholding and
surrender of the Shares subject to the Option, or (iii) by delivery (in a manner prescribed by the
Administrator) of an irrevocable direction to a securities broker approved by the Administrator to
sell Shares and to deliver all or part of the sales proceeds to the Corporation in payment of all
or part of the purchase price and any withholding taxes. Payment may also be made in any other
form approved by the Administrator, consistent with applicable law, regulations and rules.

     (d) Term and Exercise of Options.

     Each Option shall state the time or times when it may become exercisable. No Option shall be
exercisable after the expiration of seven years from the date it is granted.

     (e) Limitations on Transferability.

     An Option shall, during a Participant’s lifetime, be exercisable only by the Participant. No
Option or any right granted thereunder shall be transferable by the Participant by operation of law
or otherwise, other than by will, the laws of descent and distribution. Notwithstanding the
foregoing, (i) a Participant may designate a beneficiary to succeed, after the Participant’s death,
to all of the Participant’s Options outstanding on the date of death; (ii) a Nonstatutory Stock
Option or any right granted thereunder may be transferable pursuant to a qualified domestic
relations order as defined in the Code or Title I of the Employee Retirement Income Security Act;
and (iii) any Participant, who is a senior executive officer recommended by the Chief Executive
Officer and approved by

4

 

the Administrator may voluntarily transfer any Nonstatutory Stock Option to a Family Member as
a gift or through a transfer to an entity in which more than 50% of the voting interests are owned
by Family Members (or the Participant) in exchange for an interest in that entity. In the event of
any attempt by a Participant to alienate, assign, pledge, hypothecate, or otherwise dispose of an
Option or of any right thereunder, except as provided herein, or in the event of the levy of any
attachment, execution, or similar process upon the rights or interest hereby conferred, the
Corporation at its election may terminate the affected Option by notice to the Participant and the
Option shall thereupon become null and void.

     (f) Termination of Employment.

     Each Option Agreement shall set forth the extent to which the Participant shall have the right
to exercise the Option following termination of the Participant’s employment or service with the
Corporation and its Affiliates. Such provisions shall be determined in the sole discretion of the
Administrator, need not be uniform among all Options issued pursuant to the Plan, and may reflect
distinctions based on the reasons for termination of employment. Unless otherwise provided in
Section 3(d) and the Option Agreement, the Administrator may, in its sole discretion, extend the
post-termination exercise period with respect to an option (but not beyond the original term of
such option).

     (g) Rights as a Stockholder.

     A Participant or a transferee of a Participant shall have no rights as a stockholder with
respect to any Shares covered by his or her Option until the date of issuance of such Shares.
Except as provided in Section 16, no adjustment shall be made for dividends, distributions or other
rights for which the record date is prior to the date such Shares are issued.

     (h) Limitation of Incentive Stock Option Awards.

     If and to the extent that the aggregate Fair Market Value (determined as of the date the
Option is granted) of the Shares with respect to which any Incentive Stock Options are exercisable
for the first time by a Participant during any calendar year under this Plan and all other plans
maintained by the Corporation, its parent or its Subsidiaries exceeds $100,000, the Options
covering Shares in excess of such amount (taking into account the order in which the Options were
granted) shall be treated as Nonstatutory Stock Options.

     (i) Other Terms and Conditions.

     The Option Agreement may contain such other terms and conditions, including restrictions or
conditions on the vesting of the Option or the conditions under which the Option may be forfeited,
as may be determined by the Administrator that are consistent with the Plan.

5

 

7. STOCK APPRECIATION RIGHTS.

     Stock Appreciation Rights granted to Employees pursuant to the Plan may be granted alone, in
addition to, or in conjunction with, Options. Stock Appreciation Rights shall be evidenced by
written Stock Appreciation Right Agreements in such form as the Administrator shall determine and
shall be subject to the following terms and conditions:

     (a) Number of Shares.

     Each Stock Appreciation Right shall state the number of Shares or Share Equivalents to which
it pertains, which shall be subject to adjustment in accordance with Section 16.

     (b) Calculation of Appreciation: Exercise Price.

     The appreciation distribution payable on the exercise of a Stock Appreciation Right will be
equal to the excess of (i) the aggregate Fair Market Value (on the date of exercise of the Stock
Appreciation Right) of a number of Shares equal to the number of Shares or Share Equivalents in
which the Participant is vested under such Stock Appreciation Right on such date, over (ii) an
amount that will be determined by the Administrator on the date of grant of the Stock Appreciation
Right but that shall not be less than 100% of the Fair Market Value of a Share on the date of grant
(the “Exercise Price”).

     (c) Term and Exercise of Stock Appreciation Rights.

     Each Stock Appreciation Right shall state the time or times when may become exercisable. No
Stock Appreciation Right shall be exercisable after the expiration of seven years from the date it
is granted.

     (d) Payment.

     The appreciation distribution in respect of a Stock Appreciation Right may be paid in Common
Stock or in cash, or any combination of the two, or in any other form of consideration as
determined by the Administrator and contained in the Stock Appreciation Right Agreement.

     (e) Limitations on Transferability.

     A Stock Appreciation Right shall, during a Participant’s lifetime, be exercisable only by the
Participant. No Stock Appreciation Right or any right granted thereunder shall be transferable by
the Participant by operation of law or otherwise, other than by will, the laws of descent and
distribution. Notwithstanding the foregoing, (i) a Participant may designate a beneficiary to
succeed, after the Participant’s death, to all of the Participant’s Stock Appreciation Rights
outstanding on the date of death; (ii) a stand-alone Stock Appreciation Right or a Stock
Appreciation Right granted in conjunction with a Nonstatutory Stock Option or any right granted
thereunder may be transferable pursuant to a qualified domestic relations order as defined in the
Code or Title I of the

6

 

Employee Retirement Income Security Act; and (iii) any Participant, who is a senior executive
officer recommended by the Chief Executive Officer and approved by the Administrator may
voluntarily transfer any stand-alone Stock Appreciation Right or a Stock Appreciation Right granted
in conjunction with a Nonstatutory Stock Option to a Family Member as a gift or through a transfer
to an entity in which more than 50% of the voting interests are owned by Family Members (or the
Participant) in exchange for an interest in that entity. In the event of any attempt by a
Participant to alienate, assign, pledge, hypothecate, or otherwise dispose of a Stock Appreciation
Right or of any right thereunder, except as provided herein, or in the event of the levy of any
attachment, execution, or similar process upon the rights or interest hereby conferred, the
Corporation at its election may terminate the affected Stock Appreciation Right by notice to the
Participant and the Stock Appreciation Right shall thereupon become null and void.

     (f) Termination of Employment.

     Each Stock Appreciation Right Agreement shall set forth the extent to which the Participant
shall have the right to exercise the Stock Appreciation Right following termination of the
Participant’s employment or service with the Corporation and its Affiliates. Such provisions shall
be determined in the sole discretion of the Administrator, need not be uniform among all Stock
Appreciation Right Agreements entered into pursuant to the Plan, and may reflect distinctions based
on the reasons for termination of employment.

     (g) Rights as a Stockholder.

     A Participant or a transferee of a Participant shall have no rights as a stockholder with
respect to any Shares covered by his or her Stock Appreciation Right until the date of issuance of
such Shares. Except as provided in Section 16, no adjustment shall be made for dividends,
distributions or other rights for which the record date is prior to the date such Shares are
issued.

     (h) Other Terms and Conditions.

     The Stock Appreciation Right Agreement may contain such other terms and conditions, including
restrictions or conditions on the vesting of the Stock Appreciation Right or the conditions under
which the Stock Appreciation Right may be forfeited, as may be determined by the Administrator that
are consistent with the Plan.

8. RESTRICTED STOCK.

     (a) Grants.

     Subject to the provisions of the Plan, the Administrator shall have sole and complete
authority to determine the Employees to whom, and the time or times at which, grants of Restricted
Stock will be made, the number of shares of Restricted Stock to be awarded, the price (if any) to
be paid by the recipient of Restricted Stock, the time or times within which such Awards may be
subject to forfeiture, and all other terms and conditions of the Awards. The Administrator may
condition the grant of Restricted Stock

7

 

upon the attainment of specified performance objectives established by the Administrator
pursuant to Section 13 or such other factors as the Administrator may determine, in its sole
discretion.

     The terms of each Restricted Stock Award shall be set forth in a Restricted Stock Agreement
between the Corporation and the Participant, which Agreement shall contain such provisions as the
Administrator determines to be necessary or appropriate to carry out the intent of the Plan. A
book entry shall be made in the records of the Corporation’s transfer agent for each Participant
receiving a Restricted Stock Award, alternatively, such Participant shall be issued a stock
certificate in respect of such shares of Restricted Stock. If a certificate is issued, it shall be
registered in the name of such Participant, and shall bear an appropriate legend referring to the
terms, conditions, and restrictions applicable to such Award. The Administrator shall require that
stock certificates evidencing such shares be held by the Corporation until the restrictions lapse
and that, as a condition of any Restricted Stock Award, the Participant shall deliver to the
Corporation a “stock assignment separate from certificate” relating to the stock covered by such
Award.

     (b) Restrictions and Conditions.

     The shares of Restricted Stock awarded pursuant to this Section 8 shall be subject to the
following restrictions and conditions:

          (i) During a period set by the Administrator commencing with the date of such Award (the
“Restriction Period”), the Participant shall not be permitted to sell, transfer, pledge, assign or
encumber shares of Restricted Stock, other than pursuant to a qualified domestic relations order as
defined in the Code or Title I of the Employee Retirement Income Security Act. Within these
limits, the Administrator, in its sole discretion, may provide for the lapse of such restrictions
in installments and may accelerate or waive such restrictions in whole or in part, based on
service, performance, a Change in Control or such other factors or criteria as the Administrator
may determine in its sole discretion.

          (ii) Except as provided in this paragraph (ii) and paragraph (i) above, the Participant shall
have, with respect to the shares of Restricted Stock, all of the rights of a stockholder of the
Corporation, including the right to vote the shares and the right to receive any cash dividends.
The Administrator, in its sole discretion, as determined at the time of Award, may provide that the
payment of cash dividends shall or may be deferred and, if the Administrator so determines,
invested in additional shares of Restricted Stock to the extent available under Section 5, or
otherwise invested. Stock dividends issued with respect to Restricted Stock shall be treated as
additional shares of Restricted Stock that are subject to the same restrictions and other terms and
conditions that apply to the shares with respect to which such dividends are issued.

          (iii) The Administrator shall specify the conditions under which shares of Restricted Stock
may be forfeited and such conditions shall be set forth in the Restricted Stock Agreement.

8

 

          (iv) If and when the Restriction Period applicable to shares of Restricted Stock expires
without a prior forfeiture of the Restricted Stock, an appropriate book entry recording the
Participant’s interest in unrestricted Shares shall be entered on the records of the Corporation’s
transfer agent or, if appropriate, certificates for an appropriate number of unrestricted Shares
shall be delivered promptly to the Participant, and the certificates for the shares of Restricted
Stock shall be canceled.

9. RESTRICTED STOCK UNITS.

     (a) Grants.

     Subject to the provisions of the Plan, the Administrator shall have sole and complete
authority to determine the Employees and Directors to whom, and the time or times at which, grants
of Restricted Stock Units will be made, the number of Restricted Stock Units to be awarded, the
price (if any) to be paid by the recipient of the Restricted Stock Units, the time or times within
which such Restricted Stock Units may be subject to forfeiture, and all other terms and conditions
of the Restricted Stock Unit Awards. The Administrator may condition the grant of Restricted Stock
Unit Awards upon the attainment of specified performance objectives established by the
Administrator pursuant to Section 13 or such other factors as the Administrator may determine, in
its sole discretion.

     The terms of each Restricted Stock Unit Award shall be set forth in a Restricted Stock Unit
Award Agreement between the Corporation and the Participant, which Agreement shall contain such
provisions as the Administrator determines to be necessary or appropriate to carry out the intent
of the Plan. No book entry shall be made in the records of the Corporation’s transfer agent for a
Participant receiving a Restricted Stock Unit Award, nor shall such Participant be issued a stock
certificate in respect of such Restricted Stock Units, and the Participant shall have no right to
or interest in shares of Common Stock of the Corporation as a result of the grant of Restricted
Stock Units.

     (b) Restrictions and Conditions.

     The Restricted Stock Units awarded pursuant to this Section 9 shall be subject to the
following restrictions and conditions:

          (i) At the time of grant of a Restricted Stock Unit Award, the Administrator may impose such
restrictions or conditions on the vesting of the Restricted Stock Units, as the Administrator deems
appropriate. During such vesting period, the Participant shall not be permitted to sell, transfer,
pledge, assign or encumber the Restricted Stock Units, other than pursuant to a qualified domestic
relations order as defined in the Code or Title I of the Employee Retirement Income Security Act.
Within these limits, the Administrator, in its sole discretion, may provide for the lapse of such
restrictions in installments and may accelerate or waive such restrictions in whole or in part,
based on service, performance, a Change in Control or such other factors or criteria as the
Administrator may determine in its sole discretion.

9

 

          (ii) Dividend equivalents may be credited in respect of Restricted Stock Units, as the
Administrator deems appropriate. Such dividend equivalents may be credited on behalf of the
Participant to a deferred cash account (in a manner prescribed by the Administrator and in
compliance with Code section 409A) or converted into additional Restricted Stock Units by dividing
(1) the aggregate amount or value of the dividends paid with respect to that number of Shares equal
to the number of Restricted Stock Units then credited by (2) the Fair Market Value per Share on the
payment date for such dividend. The additional Restricted Stock Units credited by reason of such
dividend equivalents will be subject to all of the terms and conditions of the underlying
Restricted Stock Unit Award to which they relate.

          (iii) The Administrator shall specify the conditions under which Restricted Stock Units may be
forfeited and such conditions shall be set forth in the Restricted Stock Unit Agreement.

     (c) Deferral Election.

     Each recipient of a Restricted Stock Unit Award shall be entitled to elect to defer all or a
percentage of any Shares he or she may be entitled to receive upon the lapse of any restrictions or
vesting period to which the Award is subject. This election shall be made by giving notice in a
manner and within the time prescribed by the Administrator and in compliance with Code section
409A.

10. OUTSIDE DIRECTOR AWARDS.

     Each Outside Director may be granted a Restricted Stock Unit Award on the date of each annual
meeting of stockholders for up to 5,000 Share Equivalents, as determined by the Board. Such
limitation is subject to adjustment as provided in Section 16. Each Restricted Stock Unit Award
shall be fully vested on the date of grant. With respect to the grant of each Restricted Stock
Unit Award to an Outside Director prior to the date of the annual meeting of stockholders held July
23, 2008 (the “2008 Annual Meeting”), receipt of any Shares as payment for the Restricted Stock
Unit Award shall be delayed until such time as the Outside Director experiences a Separation from
Service, as defined in the McKesson Corporation Deferred Compensation Administration Plan III, as
amended, and subject to any other terms and conditions prescribed by the Administrator and in
compliance with Code section 409A (the “Automatic Deferral Requirement”). With respect to the
grant of each Restricted Stock Unit Award to an Outside Director on the date of the 2008 Annual
Meeting, and any subsequent grant of a Restricted Stock Unit Award to an Outside Director, each
Outside Director shall receive on the grant date the Shares underlying such Award; provided,
however, that the Outside Director may voluntarily elect to defer receipt of the Shares underlying
such Award by giving notice in a manner and within the time prescribed by the Administrator and in
compliance with Code section 409A, so long as at the time of any such voluntary deferral the
Outside Director satisfies the stock ownership guidelines then in effect for Outside Directors. If
the Corporation determines that the Outside Director will not satisfy such stock ownership
guidelines on the last day of the deferral election period applicable to such Award, the Automatic
Deferral Requirement shall apply as to the Shares underlying such

10

 

Award. Dividend equivalents may be credited in respect of Restricted Stock Units, as the
Administrator deems appropriate. Such dividend equivalents may be credited on behalf of the
Participant to a deferred cash account (in a manner prescribed by the Administrator and in
compliance with Code section 409A) or converted into additional Restricted Stock Units by dividing
(1) the aggregate amount or value of the dividends paid with respect to that number of Shares equal
to the number of Restricted Stock Units then credited by (2) the Fair Market Value per Share on the
payment date for such dividend. The additional Restricted Stock Units credited by reason of such
dividend equivalents will be subject to all of the terms and conditions of the underlying
Restricted Stock Unit Award to which they relate. Other terms and conditions of the Restricted
Stock Unit Awards granted to Outside Directors shall be determined by the Board subject to the
provisions of Section 9 and the Plan.

11. PERFORMANCE SHARES.

     (a) Grants.

     Subject to the provisions of the Plan, the Administrator shall have sole and complete
authority to determine the Employees to whom, and the time or times at which, grants of Performance
Shares will be made, the number of Performance Shares to be awarded, the price (if any) to be paid
by the recipient of the Performance Shares, the time or times within which such Performance Shares
may be subject to forfeiture, and all other terms and conditions of the Performance Shares.

     The terms of Performance Shares shall be set forth in a Performance Share Agreement between
the Corporation and the Participant, which Agreement shall contain such provisions as the
Administrator determines to be necessary or appropriate to carry out the intent of the Plan. With
respect to a Performance Shares, no book entry shall be made in the records of the Corporation’s
transfer agent nor shall certificate for shares of Common Stock be issued at the time the grant is
made, and the Participant shall have no right to or interest in shares of Common Stock of the
Corporation as a result of the grant of Performance Shares.

     (b) Restrictions and Conditions.

          (i) The Performance Shares awarded pursuant to this Section 11 shall be subject to the
following restrictions and conditions: The Administrator may condition the grant of Performance
Shares upon the attainment of specified performance objectives established by the Administrator
pursuant to Section 13 or such other factors as the Administrator may determine, in its sole
discretion or the Administrator may, at the time of grant of a Performance Share Award, set
performance objectives in its discretion which, depending on the extent to which they are met, will
determine the number of Performance Shares that will be paid out to the Participant. In either
case, the time period during which the performance objectives must be met is called the
“Performance Period.” After the applicable Performance Period has ended, the recipient of the
Performance Shares will be entitled to receive the number of Performance Shares earned by the
Participant over the Performance Period, to be determined as a function of the extent to

11

 

which the corresponding performance objectives have been achieved, and which shares may be
subject to additional vesting. After the grant of Performance Shares, the Administrator, in its
sole discretion, may reduce or waive any performance objective for such Performance Shares.

12. OTHER SHARE-BASED AWARDS.

     (a) Grants.

     Other Awards of Shares and other Awards that are valued in whole or in part by reference to,
or are otherwise based on, Shares (“Other Share-Based Awards”), may be granted either alone or in
addition to or in conjunction with other Awards under this Plan. Awards under this Section 12 may
include (without limitation) the grant of Shares conditioned upon some specified event, the payment
of cash based upon the performance of the Common Stock or the grant of securities convertible into
Common Stock.

     Subject to the provisions of the Plan, the Administrator shall have sole and complete
authority to determine the Employees to whom and the time or times at which Other Share-Based
Awards shall be made, the number of Shares, Share Equivalents or other securities, if any, to be
granted pursuant to Other Share-Based Awards, and all other conditions of the Other Share- Based
Awards. The Administrator may condition the grant of an Other Share-Based Award upon the
attainment of specified performance goals or such other factors as the Administrator shall
determine, in its sole discretion. In granting an Other Share-Based Award, the Administrator may
determine that the recipient of an Other Share-Based Award shall be entitled to receive, currently
or on a deferred basis, interest or dividends or dividend equivalents with respect to the Shares or
other securities covered by the Award, and the Administrator may provide that such amounts (if any)
shall be deemed to have been reinvested in additional Shares or otherwise reinvested. The terms of
any Other Share-Based Award shall be set forth in an Other Share-Based Award Agreement between the
Corporation and the Participant, which Agreement shall contain such provisions as the Administrator
determines to be necessary or appropriate to carry out the intent of the Plan.

     (b) Terms and Conditions.

     In addition to the terms and conditions specified in the Other Share-Based Award Agreement,
Other Share-Based Awards shall be subject to the following:

          (i) Any Other Share-Based Award may not be sold, assigned, transferred, pledged or otherwise
encumbered, other than pursuant to a qualified domestic relations order as defined in the Code or
Title I of the Employee Retirement Income Security Act, prior to the date on which the Shares are
issued or the Award becomes payable, or, if later, the date on which any applicable restriction,
performance or deferral period lapses.

          (ii) The Other Share-Based Award Agreement shall contain provisions dealing with the
disposition of such Award in the event of termination of the Employee’s employment or the
Director’s service prior to the exercise, realization or payment of such

12

 

Award, and the Administrator in its sole discretion may provide for payment of the Award in
the event of the Participant’s termination of employment or service with the Corporation or a
Change in Control, with such provisions to take account of the specific nature and purpose of the
Award.

13. PERFORMANCE OBJECTIVES.

     The Administrator shall determine the terms and conditions of Awards at the date of grant or
thereafter; provided that performance objectives, if any, for each year related to an Award granted
to a Covered Employee shall be established by the Administrator not later than the latest date
permissible under Section 162(m). To the extent that such Awards are paid to Covered Employees,
the performance criteria to be used shall be any of the following, either alone or in any
combination, which may be expressed with respect to the Corporation or one or more operating units
or groups, as the Compensation Committee may determine: cash flow; cash flow from operations;
total earnings; earnings per share, diluted or basic; earnings per share from continuing
operations, diluted or basic; earnings before interest and taxes; earnings before interest, taxes,
depreciation, and amortization; earnings from operations; net asset turnover; inventory turnover;
capital expenditures; net earnings; operating earnings; gross or operating margin; debt; working
capital; return on equity; return on net assets; return on total assets; return on investment;
return on capital; return on committed capital; return on invested capital; return on sales; net or
gross sales; market share; economic value added; cost of capital; change in assets; expense
reduction levels; debt reduction; productivity; stock price; customer satisfaction; employee
satisfaction; total shareholder return; average invested capital; credit rating; gross margin;
improvement in workforce diversity; operating expenses; operating expenses as a percentage of
revenue; and succession plan development and implementation. In addition, such performance goals
may be based upon the attainment of specified levels of the Corporation’s performance under one or
more of the measures described above relative to the performance of other corporations, may be (but
need not be) different from year-to-year, and different performance objectives may be applicable to
different Participants.

     Performance objectives may be determined on an absolute basis or relative to internal goals or
relative to levels attained in prior years or related to other companies or indices or as ratios
expressing relationships between two or more performance objectives. In addition, performance
objectives may be based upon the attainment of specified levels of corporate performance under one
or more of the measures described above relative to the performance of other corporations. The
Administrator shall specify the manner of adjustment of any performance objective to the extent
necessary to prevent dilution or enlargement of any Award as a result of extraordinary events or
circumstances, as determined by the Administrator, or to exclude the effects of extraordinary,
unusual, or non-recurring items; changes in applicable laws, regulations, or accounting principles;
currency fluctuations; discontinued operations; non-cash items, such as amortization, depreciation,
or reserves; asset impairment; or any recapitalization, restructuring, reorganization, merger,
acquisition, divestiture, consolidation, spin-off, split-up, combination, liquidation, dissolution,
sale of assets, or other similar corporate transaction.

13

 

14. ACCELERATION OF VESTING AND EXERCISABILITY.

     The Administrator shall have the power to accelerate the time at which an Award may first be
exercised or the time during which an Award or any part thereof will vest, notwithstanding the
provisions in the Award stating the time at which it may first be exercised or the time during
which it will vest.

15. CHANGE IN CONTROL.

     (a) An Award may be subject to additional acceleration of vesting and exercisability upon or
after a Change in Control as may be provided in the applicable agreement and determined by the
Committee on a grant by grant basis or as may be provided in any other written agreement between
the Company or any Affiliate and the Participant; provided, however, that in the absence of such
provision, no such acceleration shall occur.

     (b) A “Change in Control” of the Corporation shall be deemed to have occurred if any of the
events set forth in any one of the following paragraphs shall occur:

          (i) Any “person” (as such term is used in sections 13(d) and 14(d) of the Exchange Act),
excluding the Corporation or any of its affiliates, a trustee or any fiduciary holding securities
under an employee benefit plan of the Corporation or any of its affiliates, an underwriter
temporarily holding securities pursuant to an offering of such securities or a Corporation owned,
directly or indirectly, by stockholders of the Corporation in substantially the same proportions as
their ownership of the Corporation, is or becomes the “beneficial owner” (as defined in Rule 13d-3
under the Exchange Act), directly or indirectly, of securities of the Corporation representing 30%
or more of the combined voting power of the Corporation’s then outstanding securities; or

          (ii) During any period of not more than two consecutive years, individuals who at the
beginning of such period constitute the Board and any new director (other than a director
designated by a Person who has entered into an agreement with the Corporation to effect a
transaction described in clause (i), (iii) or (iv) of this paragraph) whose election by the Board
or nomination for election by the Corporation’s stockholders was approved by a vote of at least
two-thirds (2/3) of the directors then still in office who either were directors at the beginning
of the period or whose election or nomination for election was previously so approved, cease for
any reason to constitute a majority thereof; or

          (iii) The stockholders of the Corporation approve a merger or consolidation of the Corporation
with any other Corporation and such merger or consolidation is consummated, other than (A) a merger
or consolidation which would result in the voting securities of the Corporation outstanding
immediately prior thereto continuing to represent (either by remaining outstanding or by being
converted into voting securities of the surviving entity), in combination with the ownership of any
trustee or other fiduciary holding securities under an employee benefit plan of the Corporation, at
least 50% of the combined voting power of the voting securities of the

14

 

Corporation or such surviving entity outstanding immediately after such merger or
consolidation, or (B) a merger or consolidation effected to implement a recapitalization of the
Corporation (or similar transaction) in which no person acquires more than 50% of the combined
voting power of the Corporation’s then outstanding securities; or

          (iv) The stockholders of the Corporation approve a plan of complete liquidation of the
Corporation or an agreement for the sale or disposition by the Corporation of all or substantially
all of the Corporation’s assets.

     Notwithstanding the foregoing, no Change in Control shall be deemed to have occurred if there
is consummated any transaction or series of integrated transactions immediately following which the
holders of the Stock immediately prior to such transaction or series of transactions continue to
have the same proportionate ownership in an entity which owns all or substantially all of the
assets of the Corporation immediately prior to such transaction or series of transactions.

16. RECAPITALIZATION.

     In the event that the Administrator, in its sole discretion, shall determine that any dividend
or other distribution (whether in the form of cash, stock, or other property), recapitalization,
stock split, reverse stock split, reorganization, merger, consolidation, spin-off, combination,
repurchase, or share exchange, or other similar corporate transaction or event, affects the Common
Stock such that an adjustment is appropriate in order to preserve (but not increase) the rights of
participants under the Plan, then the Administrator shall make such equitable changes or
adjustments as it deems necessary or appropriate to any or all of (i) the number and kind of shares
which may thereafter be issued in connection with respect to Awards pursuant to Sections 4(b) and
5, (ii) the number and kind of shares issued in respect of outstanding Awards, and (iii) the
Exercise Price relating to any Options or Stock Appreciation Right.

17. TERM OF PLAN.

     Awards may be granted pursuant to the Plan until the termination of the Plan on May 24, 2015.

18. SECURITIES LAW REQUIREMENTS AND LIMITATION OF RIGHTS.

     (a) Securities Law.

     No Shares shall be issued pursuant to the Plan unless and until the Corporation has determined
that: (i) it and the Participant have taken all actions required to register the Shares under the
Securities Act of 1933 or perfected an exemption from registration; (ii) any applicable listing
requirement of any stock exchange on which the Common Stock is listed has been satisfied; and (iii)
any other applicable provision of state or federal law has been satisfied.

15

 

     (b) Employment Rights.

     Neither the Plan nor any Award granted under the Plan shall be deemed to give any individual a
right to remain employed by the Corporation or an Affiliate or to remain in service as a Director.
The Corporation and its Affiliates reserve the right to terminate the employment of any Employee at
any time, with or without cause or for no cause, subject only to a written employment contract (if
any), and the Board reserves the right to terminate a Director’s membership on the Board for cause
in accordance with the Corporation’s Certificate of Incorporation.

     (c) Stockholders’ Rights.

     Except as otherwise provided in the Plan, a Participant shall have no dividend rights, voting
rights or other rights as a stockholder with respect to any Shares covered by his or her Award
prior to an appropriate book entry recording the Participant’s interest in Shares being entered on
the records of the Corporation’s transfer agent or, if appropriate, the issuance of a stock
certificate for such Shares. No adjustment shall be made for cash dividends or other rights for
which the record date is prior to the date when such book entry is made or such certificate is
issued.

19. AWARDS IN FOREIGN COUNTRIES.

     The Administrator shall have the authority to adopt such modifications, rules, procedures and
subplans as may be necessary or desirable to facilitate compliance with the provisions of the laws
and procedures of foreign countries in which the Corporation or its Affiliates may operate to
assure the viability of the benefits of Awards made to Participants employed in such countries and
to meet the intent of the Plan.

20. BENEFICIARY DESIGNATION.

     Participants and their Beneficiaries may designate on the prescribed form one or more
Beneficiaries to whom distribution shall be made of any Award outstanding at the time of the
Participant’s or Beneficiary’s death. A Participant or Beneficiary may change such designation at
any time by filing the prescribed form with the Administrator. If a Beneficiary has not been
designated or if no designated Beneficiary survives the Participant, distribution will be made to
the Participant’s spouse, or if none, the Participant’s children in equal shares, or if none, to
the residuary beneficiary under the terms of the Participant’s or Beneficiary’s last will and
testament or, in the absence of a last will and testament, to the Participant’s or Beneficiary’s
estate as Beneficiary. Notwithstanding the foregoing, the Administrator may prescribe specific
methods, restrictions on or eliminate beneficiary designations made by Participants or
Beneficiaries located outside of the United States.

21. AMENDMENT OF THE PLAN.

     The Board may suspend or discontinue the Plan at any time. The Compensation Committee may
amend the Plan with respect to any Shares at the time not subject to

16

 

Awards; provided, however, that only the Board may amend the Plan and submit the Plan to the
stockholders of the Corporation for approval with respect to amendments that:

     (a) Increase the number of Shares available for issuance under the Plan or increase the number
of Shares available for issuance pursuant to Incentive Stock Options under the Plan;

     (b) Materially expand the class of persons eligible to receive Awards;

     (c) Expand the types of awards available under the Plan;

     (d) Materially extend the term of the Plan;

     (e) Materially change the method of determining the Exercise Price or purchase price of an
Award;

     (f) Delete or limit the requirements of Section 22;

     (g) Remove the administration of the Plan from the Administrator; or

     (h) Amend this Section 21 to defeat its purpose.

22. NO AUTHORITY TO REPRICE.

     Without the consent of the stockholders of the Corporation, except as provided in Section 16,
the Administrator shall have no authority to effect either (i) the repricing of any outstanding
Options or Stock Appreciation Rights under the Plan or (ii) the cancellation of any outstanding
Options or Stock Appreciation Rights under the Plan and the grant in substitution therefor of new
Options or Stock Appreciation Rights under the Plan covering the same or different numbers of
Shares.

23. RECOUPMENT.

     Awards are subject to the Corporation’s Compensation Recoupment Policy, which was first
adopted by the Corporation on January 20, 2010, as amended from time to time, and which is hereby
incorporated by reference into this Plan.

24. USE OF PROCEEDS FROM STOCK.

     Proceeds from the sale of Common Stock pursuant to Awards shall constitute general funds of
the Corporation.

25. NO OBLIGATION TO EXERCISE OPTION OR STOCK APPRECIATION RIGHT.

     The granting of an Option or Stock Appreciation Right shall impose no obligation upon the
Participant to exercise such Option or Stock Appreciation Right.

17

 

26. APPROVAL OF STOCKHOLDERS.

     This Plan and any amendments requiring stockholder approval pursuant to Section 21 shall be
subject to approval by affirmative vote of the stockholders. Such vote shall be taken at the first
annual meeting of stockholders of the Corporation following the adoption of the Plan or of any such
amendments, or any adjournment of such meeting.

27. GOVERNING LAW.

     The law of the State of Delaware shall govern all question concerning the construction,
validity and interpretation of the Plan, without regard to the state’s conflict of laws rules.

28. INTERPRETATION.

     The Plan is designed and intended to comply with Rule 16b-3 promulgated under the Exchange
Act, Code section 162(m), and Code section 409A and guidance promulgated thereunder, and all
provisions hereof shall be construed in a manner to so comply.

29. WITHHOLDING TAXES.

     (a) General.

     To the extent required by applicable law, the recipient of any payment or distribution under
the Plan shall make arrangements satisfactory to the Corporation for the satisfaction of any
required income tax, social insurance, payroll tax or other tax related to withholding obligations
that arise by reason of such payment or distribution. The Corporation shall not be required to
make such payment or distribution until such obligations are satisfied.

     (b) Other Awards.

     The Administrator may permit a Participant who exercises an Option or Stock Appreciation Right
or who vests in an other Award to satisfy all or part of his or her withholding tax obligations by
having the Corporation withhold a portion of the Shares that otherwise would be issued to him or
her under such Awards. Such Shares shall be valued at the Fair Market Value on the date when taxes
otherwise would be withheld in cash. The payment of withholding taxes by surrendering Shares to

OUTSIDE DIRECTORS

FORM OF

McKESSON CORPORATION

STATEMENT OF TERMS AND CONDITIONS APPLICABLE TO

RESTRICTED STOCK UNITS GRANTED TO

OUTSIDE DIRECTORS PURSUANT TO THE 2005 STOCK PLAN

(Effective as of April 20, 2010)

I. INTRODUCTION

     The following terms and conditions shall apply to Restricted Stock Unit Awards granted under
the Plan to Outside Directors eligible to participate in the Plan. This Statement of Terms and
Conditions is intended to meet the requirements of Code Section 409A and any regulations and rules
promulgated thereunder and is subject to the terms and conditions of the Plan. In the event of any
inconsistency between this Statement of Terms and Conditions and the Plan, the Plan shall govern.
Capitalized terms not otherwise defined in this Statement of Terms and Conditions shall have the
meaning set forth in the Plan.

II. RESTRICTED STOCK UNITS

     1. Award Agreement. A Restricted Stock Unit Award granted to an Outside Director
under the Plan shall be evidenced by a Restricted Stock Unit Agreement to be executed by the
Outside Director and the Corporation setting forth the terms and conditions of the Restricted Stock
Unit Award. Each Restricted Stock Unit Agreement shall incorporate by reference and be subject to
this Statement of Terms and Conditions and the terms and conditions of the Plan.

     2. Terms and Conditions. The Administrator administering the Plan has authority to
determine the Outside Directors to whom, and the time or times at which, grants of Restricted Stock
Units will be made, the number of Units to be awarded, and all other terms and conditions of such
awards. With respect to annual Restricted Stock Unit Awards granted to Outside Directors under the
Plan, such awards shall contain the following terms, conditions and restrictions.

          (A) Grant Date. Each Outside Director may be granted a Restricted Stock Unit Award on
the date of each annual meeting of stockholders. An Outside Director that is elected to the Board
between annual meetings of stockholders may also be granted a Restricted Stock Unit Award on the
date that the Board determines in its sole discretion.

          (B) Number of Units. The number of Units granted for the annual grant will be
determined by dividing the closing stock price on the date of grant into $150,000 (with any
fractional Unit rounded up to the nearest whole Unit) so long as the number of Units does not
exceed 5,000 in any year. A newly elected Outside Director may receive a prorated grant effective
upon the date of his or her election to the Board.

1.

 

Outside Directors

          (C) No Restrictions. Each Restricted Stock Unit Award granted to an Outside Director
will be fully vested on the date of grant.

     3. Dividend Equivalents. Dividend equivalents in respect of Restricted Stock Units
may be credited on behalf of an Outside Director to a deferred cash account or converted into
additional Restricted Stock Units, which will be subject to all of the terms and conditions of the
underlying Restricted Stock Unit Award. Currently, dividend equivalents in respect of Restricted
Stock Units granted to Outside Directors are credited to a deferred cash account.

     4. Assignability. An Outside Director shall not be permitted to sell, transfer,
pledge, assign or encumber Restricted Stock Units, other than pursuant to a qualified domestic
relations order as defined in the Code or Title I of the U.S. Employee Retirement Income Security
Act.

     5. No Stockholder Rights. Neither an Outside Director nor any person entitled to
exercise an Outside Director’s rights in the event of the Outside Director’s death shall have any
of the rights of a stockholder with respect to the Share Equivalents subject to a Restricted Stock
Unit Award except to the extent that a book entry has been entered in the records of the
Corporation’s transfer agent with respect to the underlying Shares upon the payment of any
Restricted Stock Unit Award as described in Section II.6 below.

     6. Time of Payment of Restricted Stock Units. Except as noted in Section II.7 below,
Restricted Stock Units granted to Outside Directors shall not be paid until after the Outside
Director’s separation from service with the Corporation (“Automatic Deferral Requirement”).
“Separation of service” shall have the meaning provided under the McKesson Corporation Deferred
Compensation Administration Plan III (“DCAP III”). Payment shall be made in Shares in the form of
an appropriate book entry entered in the records of the Corporation’s transfer agent recording the
Outside Director’s unrestricted interest in the number of Shares equal to the number of Share
Equivalents subject to the Restricted Stock Unit Award.

     7. Satisfaction of Director Stock Ownership Guidelines. For those Outside Directors
who have met the Director Stock Ownership Guidelines in effect at the time, Restricted Stock Unit
grants made on or after the date of the annual meeting of stockholders held on July 23, 2008 shall
not be subject to the Automatic Deferral Requirement and such grants will be immediately converted
into Shares and distributed to the Outside Director; provided, however, that the Outside Director
may elect to defer receipt of the Shares underlying the Restricted Stock Units.

     8. Deferrals of Restricted Stock Units. Deferrals of Restricted Stock Units, whether
elective or pursuant to the Automatic Deferral Requirement, shall be subject to the terms and
conditions of DCAP III.

III. MISCELLANEOUS

     1. No Effect on Terms of Service with the Corporation. Nothing contained in this
Statement of Terms and Conditions, the Plan or a Restricted Stock Unit Agreement shall affect the
Corporation’s right to terminate the service of any Outside Director.

2.

 

Outside Directors

     2. Grants to Outside Directors in Foreign Countries. If an Outside Director is not a
United States citizen, the Board has the full discretion to deviate from this Statement of Terms
and Conditions in order to adjust a Restricted Stock Unit Award to prevailing local conditions,
including custom and legal and tax requirements. Furthermore, the Corporation reserves the right
to impose other requirements on the Outside Director’s participation in the Plan on the Award and
on any Shares acquired under the Plan, to the extent the Corporation determines it is necessary or
advisable in order to comply with local law or facilitate the administration of the Plan, and to
require the Outside Director to sign any additional agreements or undertaking that may be necessary
to accomplish the foregoing.

     3. Information Notification. Any information required to be given under the terms of
a Restricted Stock Unit Award shall be addressed to the Corporation in care of its Corporate
Secretary at McKesson Plaza, One Post Street, San Francisco, California 94104, and any notice to be
given to an Outside Director shall be addressed to him or her at the address indicated beneath his
or her name on the Restricted Stock Unit Agreement or such other address as either party may
designate in writing to the other. Any such notice shall be deemed to have been duly given when
enclosed in a properly sealed envelope or wrapper addressed as aforesaid, registered or certified
and deposited (postage or registration or certification fee prepaid) in a post office or branch
post office.

     4. Administrator Decisions Conclusive. All decisions of the Administrator
administering the Plan upon any questions arising under the Plan, under this Statement of Terms and
Conditions, or under a Restricted Stock Unit Agreement, shall be conclusive.

     5. No Effect on Other Benefit Plans. Nothing herein contained shall affect an Outside
Director’s right, if any, to participate in and receive benefits from and in accordance with the
then current provisions of any benefit plan or program offered by the Corporation.

     6. Withholding. Each Outside Director shall agree to make appropriate arrangements
with the Corporation for satisfaction of any applicable federal, state or local income tax
withholding requirements or payroll tax requirements, if any is required.

OFFICER PURSUANT TO THE 2005 STOCK PLAN

(Effective as of April 20, 2010)

I. INTRODUCTION

     The following terms and conditions shall apply to an Award granted under the Plan. This
Statement of Terms and Conditions is intended to meet the requirements of Code Section 409A and any
rules promulgated thereunder and is subject to the terms and conditions of the Plan. In the event
of any inconsistency between this Statement of Terms and Conditions and the Plan, the Plan shall
govern. Capitalized terms not otherwise defined in this Statement of Terms and Conditions shall
have the meaning set forth in the Plan.

II. OPTIONS

     1. Option Notice and Agreement. An Option granted under the Plan shall be evidenced
by an Option Agreement setting forth the terms and conditions of the Option, including whether the
Option is an Incentive Stock Option or a Nonstatutory Stock Option and the number Shares subject to
the Option. Each Option Agreement shall incorporate by reference and be subject to this Statement
of Terms and Conditions and the terms and conditions of the Plan.

     2. Exercise Price. The per Share Exercise Price of an Option, as specified in the
Option Agreement, shall be equal to or greater than the per Share Fair Market Value of the Shares
underlying the Option on the Grant Date.

     3. Option Period. An Option shall be exercisable only during the applicable Option
Period, and during such Option Period the exercisability of the Option shall be subject to the
vesting provisions of Section II.4 as modified by the rules set forth in Sections II.5 and V. The
Option Period shall be not more than seven years from the Grant Date.

     4. Vesting of Right to Exercise Options.

          (A) Except as provided in Section V, an Option shall be exercisable during the Option Period
in accordance with the following vesting schedule: (i) 25% of the Shares subject to the Option
shall vest on the first anniversary of the Grant Date; (ii) an additional 25% of the Shares shall
vest on the second anniversary of the Grant Date; (iii) an additional 25% of the Shares shall vest
on the third anniversary of the Grant Date; and (iv) the remaining 25% of the Shares subject to the
Option shall vest on the fourth anniversary of the Grant Date. Notwithstanding the foregoing, the
Administrator may specify a different vesting schedule at the time the Option is granted, which
will be specified in the Option Agreement.

1.

 

CEO

          (B) Any vested portion of an Option not exercised hereunder shall accumulate and be
exercisable at any time on or before the Termination Date, subject to the rules set forth in
Section V. No Option may be exercised for less than 5% of the total number of Shares then
available for exercise under such Option. In no event shall the Corporation be required to issue
fractional Shares.

     5. Limits on Option Period and Acceleration of Vesting. The Option Period may end
before the Termination Date, and in the circumstances described in Sections II.5(B), (D), (E) and
(F), the vesting schedule of an Option may be accelerated, (subject to the provisions of
Section V), as follows:

          (A) If a Participant ceases to be a bona fide employee of the Corporation or of its Affiliates
during the Option Period for reasons other than for Cause (as defined herein), Long-Term
Disability, Normal or Early Retirement or death, the Option Period shall end ninety days after the
date of the Participant’s termination of employment or on the Termination Date, whichever occurs
first and in all cases the Option shall be exercisable only to the extent that it was exercisable
under the provisions of the foregoing Section II.4 at the time of such termination of employment.
If a Participant is absent from work with the Corporation or an Affiliate because of his Short-Term
Disability or because the Participant is on an approved leave of absence, the Participant shall not
be deemed during the period of any such absence, by virtue of such absence alone, to have
terminated employment with the Corporation or an Affiliate except as the Administrator may
otherwise expressly determine. Notwithstanding the foregoing, if the Participant is on a
voluntarily leave of absence for the purpose of serving the government of the country of which the
Participant is a citizen or in which the Participant’s principal place of employment is located and
such leave exceeds twelve months in duration, then the Participant shall be deemed to have
terminated employment with the Corporation or an Affiliate for purposes of this Section II.5(A).

          (B) If a Participant ceases to be a bona fide employee of the Corporation or of its Affiliates
(for reasons other than for Cause, Long-Term Disability, Normal or Early Retirement or
death) during the Option Period, the Administrator may, in its sole and absolute discretion (and
subject to conditions deemed appropriate in the circumstances) approve the continuation of the
vesting schedule of the Participant’s Option. The Option Period for any Option that continues to
vest pursuant to this subsection (B) shall end ninety days after the last Option installment vests,
or on the Termination Date, whichever occurs first.

          (C) If the Participant’s employment is terminated for Cause during the Option Period, the
Option Period shall end on the date of such termination of employment and the Option shall
thereupon not be exercisable to any extent whatsoever.

          (D) If a Participant ceases to be a bona fide employee of the Corporation or of its Affiliates
due to his Long-Term Disability during the Option Period, the vesting schedule of the Participant’s
Option shall be accelerated, the Option shall become fully exercisable and the Option Period shall
end three years after the date of the Participant’s termination of employment or on the Termination
Date, whichever occurs first.

          (E) If the Participant’s employment is terminated:

2.

 

CEO

               (i) by reason of Normal Retirement, the vesting schedule of the Participant’s Option shall be
accelerated and the Option shall become fully exercisable as of the date of Normal Retirement; or

               (ii) by reason of Early Retirement, the Option shall be exercisable only to the extent that it
was exercisable under the provisions of the foregoing Section II.4 at the time of such Early
Retirement; provided, however, that the Administrator may, in its sole discretion (and subject to
conditions deemed appropriate in the circumstances), either (A) accelerate the vesting schedule of
the Participant’s Option effective as of the date of the Participant’s Early Retirement or
(B) approve the continuation of the vesting schedule of the Participant’s Option.

               (iii) With respect to an Option held by a Participant at Normal or Early Retirement, the
Option Period for that portion of the Option designated as a Nonstatutory Stock Option shall end
three years after the date of retirement or on the Termination Date, whichever occurs first;
provided, however, that in the case of an Option held by a Participant at Early Retirement as to
which the Administrator exercises its discretionary authority to approve the continuation of the
vesting schedule, the Option Period shall end on the earlier of the Termination Date or three years
after the last Option installment vests.

          (F) If a Participant should die while in the employ of the Corporation or an Affiliate and
during the Option Period, the vesting schedule of the Participant’s Option shall be accelerated and
the Option shall become fully exercisable, the Option Period shall end three years after the date
of death or on the Termination Date, whichever occurs first, and the Participant’s Beneficiary may
exercise the entire unexercised portion of the then exercisable Shares covered by such Option (or
any lesser amount) remaining on the date of death.

          (G) If a Participant who ceases to be a bona fide employee of the Corporation or an Affiliate
is subsequently rehired prior to the expiration of his Option, then the Option shall continue to
remain outstanding until such time as the Participant subsequently terminates employment. Upon the
Participant’s subsequent termination of employment, the post-termination exercise period calculated
pursuant to the terms and conditions of this Section II.5 shall be reduced by the number of days
between the date of the Participant’s initial termination of employment and his re-hire date;
provided, however, that if the rehired Participant continues to be employed by the Corporation or
an Affiliate for at least one year from his rehire date, then the post termination exercise period
for the Option shall be determined in accordance with Sections II.5(A) through (F) and shall not be
adjusted as described above.

     6. Method of Exercise. A Participant may exercise an Option with respect to all or
any part of the exercisable Shares as follows:

          (A) By giving the Corporation, or its authorized representative designated for this purpose,
written notice of such exercise specifying the number of Shares as to which the Option is so
exercised. Such notice shall be accompanied by an amount equal to the Exercise Price of such
Shares, in the form of any one or combination of the following: cash or a certified check, bank
draft, postal or express money order payable to the order of the Corporation in lawful money of the
United States. Unless otherwise determined by the Administrator in his or her sole discretion, the
Participant may pay the Exercise Price, in whole or in part, by tendering

3.

 

CEO

	 

	to the Corporation or its authorized representative Shares which have been owned by the
Participant for at least six months prior to said tender, and having a fair market value, as
determined by the Corporation, equal to the Exercise Price, or in lieu of the delivery of actual
Shares in such tender, the Corporation may accept an attestation by the Participant, in a form
prescribed by the Corporation or its authorized representative, that the Participant owns
sufficient Shares of record or in an account in street name to satisfy the Exercise Price, and such
attestation will be deemed a tender of Shares for purposes of this method of exercise. In the
event a Participant tenders Shares to pay the Exercise Price, tender of Shares acquired through
exercise of an Incentive Stock Option may result in unfavorable income tax consequences unless such
Shares are held for at least two years from the Grant Date of the Incentive Stock Option and one
year from the date of exercise of the Incentive Stock Option. The Corporation or its authorized
representative may accept payment of the Exercise Price in the form of a Participant’s personal
check. Payment may also be made by delivery (including by FAX transmission) to the Corporation or
its authorized representative of an executed irrevocable Option exercise form together with
irrevocable instructions to an approved registered investment broker to sell Shares in an amount
sufficient to pay the Exercise Price plus any applicable withholding taxes and to transfer the
proceeds of such sale to the Corporation.

          (B) If required by the Corporation, by giving satisfactory assurance in writing, signed by the
Participant, the Participant shall give his assurance that the Shares subject to the Option are
being purchased for investment and not with a view to the distribution thereof; provided that such
assurance shall be deemed inapplicable to (1) any sale of the Shares by such Participant made in
accordance with the terms of a registration statement covering such sale, which has heretofore been
(or may hereafter be) filed and become effective under the U.S. Securities Act of 1933, as amended
(the “Securities Act”) and with respect to which no stop order suspending the effectiveness thereof
has been issued, and (2) any other sale of the Shares with respect to which, in the opinion of
counsel for the Corporation, such assurance is not required to be given in order to comply with the
provisions of the Securities Act.

          (C) As soon as practicable after receipt of the notice and the assurance described in
Sections II.6(A) and (B), the Corporation shall, without transfer or issue tax (except for
withholding tax arrangements contemplated in Section VII.6) and without other incidental expense to
the Participant, cause an appropriate book entry to be entered in the records of the Corporation’s
transfer agent recording the Participant’s unrestricted interest in the purchased Shares; provided,
however, that the time of such delivery may be postponed by the Corporation for such period as may
be required for it with reasonable diligence to comply with applicable registration requirements
under the Securities Act, the Exchange Act, any applicable listing requirements of any national
securities exchange and requirements under any other law or regulation applicable to the issuance
or transfer of the Shares.

     7. Limitations on Transfer. An Option shall, during a Participant’s lifetime, be
exercisable only by the Participant. No Option or any right granted thereunder shall be
transferable by the Participant by operation of law or otherwise, other than by will or the laws of
descent and distribution. Notwithstanding the foregoing, (i) a Participant may designate a
beneficiary to succeed, after the Participant’s death, to all of the Participant’s Options
outstanding on the date of death; (ii) a Nonstatutory Stock Option may be transferable pursuant to
a qualified domestic relations order as defined in the Code or Title I of the U.S. Employee

4.

 

CEO

Retirement Income Security Act; and (iii) any Participant, who is a senior executive officer
recommended by the Chief Executive Officer of the Corporation and approved by the Administrator may
voluntarily transfer any Nonstatutory Stock Option to a Family Member as a gift or through a
transfer to an entity in which more than 50% of the voting interests are owned by Family Members
(or the Participant) in exchange for an interest in that entity. In the event of any attempt by a
Participant to alienate, assign, pledge, hypothecate, or otherwise dispose of an Option or of any
right thereunder, except as provided herein, or in the event of the levy of any attachment,
execution, or similar process upon the rights or interest hereby conferred, the Corporation at its
election may terminate the affected Option by notice to the Participant and the Option shall
thereupon become null and void.

     8. No Shareholder Rights. Neither a Participant nor any person entitled to exercise a
Participant’s rights in the event of the Participant’s death shall have any of the rights of a
shareholder with respect to the Shares subject to an Option except to the extent that a book entry
has been entered in the records of the Corporation’s transfer agent with respect to such Shares
upon the exercise of an Option.

III. RESTRICTED STOCK

     1. Restricted Stock Agreement. A Restricted Stock Award granted under the Plan shall
be evidenced by a Restricted Stock Agreement to be executed by the Participant and the Corporation
setting forth the terms and conditions of the Restricted Stock Award. Each Restricted Stock
Agreement shall incorporate by reference and be subject to this Statement of Terms and Conditions
and the terms and conditions of the Plan.

     2. Rights with Respect to Shares of Restricted Stock. Upon written acceptance of a
grant of Restricted Stock Award by a Participant, including the restrictions and other terms and
conditions described in the Plan, the Restricted Stock Agreement and herein, the Corporation shall
cause an appropriate book entry to be entered in the records of the Corporation’s transfer agent
recording the Participant’s interest in the Restricted Stock. From and after the Grant Date, the

to vote and to receive dividends thereon, subject to the terms, conditions and restrictions
described in the Plan, the Restricted Stock Agreement and this Statement of Terms and Conditions.

     3. Special Restrictions. Each Restricted Stock Award made under the Plan shall
contain the following terms, conditions and restrictions and such additional terms, conditions and
restrictions as may be determined by the Administrator; provided, however, that no Restricted Stock
grant shall be subject to additional terms, conditions and restrictions which are more favorable to
a Participant than the terms, conditions and restrictions set forth elsewhere in the Plan, the
Restricted Stock Agreement or this Statement of Terms and Conditions.

          (A) Restrictions. Until the restrictions imposed on any Restricted Stock grant shall
lapse, Shares of Restricted Stock granted to a Participant: (i) shall not be sold, assigned,
transferred, pledged, hypothecated, or otherwise disposed of, other than pursuant to a qualified
domestic relations order as defined in the Code or Title I of the U.S. Employee Retirement Income
Security Act and (ii) shall, if the Participant’s continuous employment with the

5.

 

CEO

Corporation or any of its Affiliates shall terminate for any reason (except as otherwise
provided in the Plan or in Section III.3(B)) be returned to the Corporation forthwith, and all the
rights of the Participant to such Shares shall immediately terminate. If a Participant is absent
from work with the Corporation or an Affiliate because of his Short-Term Disability or because the
Participant is on an approved leave of absence, the Participant shall not be deemed during the
period of any such absence, by virtue of such absence alone, to have terminated employment with the
Corporation or an Affiliate except as the Administrator may otherwise expressly determine.
Notwithstanding the foregoing, if the Participant is on a voluntarily leave of absence for the

the Participant’s principal place of employment is located and such leave exceeds twelve months in
duration, then the Participant shall be deemed to have terminated employment with the Corporation
or an Affiliate for purposes of this Section III.3(A).

          (B) Termination of Employment by Reason of Death, Long-Term Disability or Normal

Corporation or any of its Affiliates since the Grant Date of a Restricted Stock Award ceases to be
a bona fide employee of the Corporation or an Affiliate as a result of death, Long-Term Disability,
or Normal Retirement, then the restrictions imposed on any Restricted Stock Award shall lapse as to
all Shares granted to such Participant pursuant to such Restricted Stock Award on the date of such
termination.

          (C) Termination of Employment by Reason of Early Retirement. Notwithstanding any
provision contained herein or in the Plan or the Restricted Stock Agreement to the contrary, if a
Participant who has been in the continuous employment of the Corporation or any of its Affiliates
since the Grant Date of a Restricted Stock Award ceases to be a bona fide employee of the
Corporation or an Affiliate by reason of Early Retirement, the Administrator may, in its sole
discretion (and subject to conditions deemed appropriate in the circumstances), accelerate the
vesting schedule of the Participant’s Restricted Stock Award effective as of the date of the
Participant’s Early Retirement.

          (D) Restriction on Sale. The Compensation Committee reserves the right to impose a
restriction on the sale of Shares that the Participant receives upon the vesting and settlement of
a Restricted Stock Award, unless the Participant has satisfied the ownership targets applicable to
the Participant as provided in the Stock Ownership Policy.

     4. Dividends. Cash dividends paid with respect to the Restricted Stock during the
Restriction Period shall be paid directly to the Participant during the Restriction Period. Stock
dividends paid with respect to Restricted Stock during the Restriction Period shall be treated as
Restricted Stock which shall be subject to the same restrictions as the original award for the
duration of the Restricted Period.

     5. Election to Recognize Gross Income in the Year of Grant. If any Participant
validly elects within thirty days of the Grant Date, to include in gross income for federal income
tax purposes an amount equal to the fair market value of the Shares of Restricted Stock granted on
the Grant Date, such Participant shall pay to the Corporation, or make arrangements satisfactory to
the Administrator to pay to the Corporation in the year of such grant, any federal,

CEO

state or local taxes required to be withheld with respect to such Shares in accordance with
Section VII.6.

     6. Restrictive Legend. Each book entry in the records of the Corporation’s transfer
agent evidencing Shares granted pursuant to a Restricted Stock grant may bear an appropriate legend
referring to the terms, conditions and restrictions described in the Plan, the Restricted Stock
Agreement and this Statement of Terms and Conditions.

     7. Expiration of Restricted Period. If and when the Restriction Period applicable to
the Restricted Stock expires without a prior forfeiture, an appropriate book entry recording the
Participant’s interest in the unrestricted Shares shall be entered on the records of the
Corporation’s transfer agent.

IV. RESTRICTED STOCK UNITS AND PERFORMANCE SHARES

     1. Award Agreement.

          (A) A Restricted Stock Unit Award granted under the Plan shall be evidenced by a Restricted

incorporate by reference and be subject to this Statement of Terms and Conditions and the terms and
conditions of the Plan.

          (B) Performance Shares granted under the Plan shall be evidenced by a Performance Share

under the Plan shall contain the following terms, conditions and restrictions and such additional
terms, conditions and restrictions as may be determined by the Administrator; provided, however,

and Conditions.

Units or Performance Shares shall be returned to the Corporation, and all the rights of the
Participant to such Share Equivalents shall immediately terminate. If a Participant is absent from
work with the Corporation or an Affiliate because of his Short-Term Disability or because the
Participant is on an approved leave of absence, the Participant shall not be deemed during the
period of any such absence, by virtue of such absence alone, to have terminated employment with the
Corporation or an Affiliate except as the Administrator may otherwise expressly determine.
Notwithstanding the foregoing, if the Participant is on a voluntarily leave of absence for the
purpose of serving the government of the country of which the Participant is a citizen or

twelve months in duration, then the Participant shall be deemed to have terminated employment with
the Corporation or an Affiliate for purposes of this Section IV.2(A).

          (B) Termination of Employment by Reason of Death, Long-Term Disability or Normal

in the continuous employment of the Corporation or any of its Affiliates since the Grant Date
shall, while in such employment, be terminated as a result of death, Long-Term Disability, or
Normal Retirement, then the restrictions imposed on any Restricted Stock Unit Award or Performance
Shares shall lapse as to all Share Equivalents granted to such Participant pursuant to such Award
on the date of such termination.

          (C) Termination of Employment by Reason of Early Retirement. Notwithstanding any
provision contained herein or in the Plan or the Restricted Stock Unit Agreement or Performance
Share Agreement to the contrary, if a Participant who has been in continuous employment of the
Corporation or any of its Affiliates since the Grant Date of a Restricted Stock Unit Award or
Performance Share Award ceases to be a bona fide employee of the Corporation or an Affiliate by
reason of Early Retirement, the Administrator may, in its sole discretion (and subject to

Restricted Stock Units and Performance Shares. Cash dividends shall be credited on behalf of the
Participant to a deferred cash account (in a manner designed to comply with Code Section 409A).

which will be subject to all of the terms and conditions of the underlying Restricted Stock Unit
Award or Performance Shares, including the same vesting restrictions as the underlying award.

     4. Assignability. A Participant shall not be permitted to sell, transfer, pledge,
assign or encumber Restricted Stock Units or Performance Shares, other than pursuant to a qualified
domestic relations order as defined in the Code or Title I of the U.S. Employee Retirement Income
Security Act.

     5. No Shareholder Rights. Neither a Participant nor any person entitled to exercise a

Restricted Stock Unit Award of Performance Shares.

8.

 

CEO

     6. Time of Payment of Restricted Stock Units and Performance Shares. Upon the lapse
of the restriction imposed on Restricted Stock Unit Awards or Performance Shares, all Restricted
Stock Units and Performance Shares that were not forfeited pursuant to Sections IV.2(A) or V shall
be paid to the Participant as soon as reasonably practicable after the restrictions lapse. Payment
shall be made in Shares in the form of a an appropriate book entry entered in the records of the
Corporation’s transfer agent recording the Participant’s unrestricted interest in the number of

of the Restricted Stock Units in the manner described in Section IV.7.

     7. Deferral Election. Each Participant, pursuant to rules established by the

Restricted Stock Unit Award that he or she may be entitled to receive as determined pursuant to
Section IV.6. This election shall be made by giving notice in a manner and within the time
prescribed by the Administrator and in compliance with Code Section 409A. If a deferral is
permitted, the Participant must indicate the percentage (expressed in whole percentages) he or she
chooses to defer of any payment he or she may be entitled to receive. If no notice is given, the
Participant shall be deemed to have made no deferral election. Each deferral election filed with

     Any other provision of this Statement of Terms and Conditions to the contrary notwithstanding,

below, the consequences set forth in 1 and 2 below shall result:

     1. Any outstanding Option shall immediately and automatically terminate, be forfeited and
shall cease to be exercisable, without limitation. In addition, any Shares of Restricted Stock,
Restricted Stock Units or Performance Shares as to which the restrictions on vesting have not
lapsed shall immediately and automatically be forfeited and such Shares or Share Equivalents shall
be returned to the Corporation and all of the rights of the Participant to such Shares or Share
Equivalents shall immediately terminate.

     2. If the Participant exercised an Option within twelve months prior to the date upon which
the Corporation discovered that the Participant engaged in any actions described in 3 below, the
Participant, upon written notice from the Corporation, shall immediately pay to the Corporation the
economic value realized or obtained by the exercise of such Option measured at the date of

the Performance Shares, measured at the date such Shares or Share Equivalents vested.

9.

 

CEO

     3. The consequences described in 1 and 2 above shall apply if the Participant, either before
or after termination of employment with the Corporation or its Affiliates:

          (A) Discloses to others, or takes or uses for his own purpose or the purpose of others, any
trade secrets, confidential information, knowledge, data or know-how or any other proprietary
information or intellectual property belonging to the Corporation or its Affiliates and obtained by

retirement or otherwise;

          (C) Fails to provide the Corporation with at least thirty (30) days’ written notice prior to
directly or indirectly engaging in, becoming employed by, or rendering services, advice or
assistance to any business in competition with the Corporation or its Affiliates. As used herein,

the time of the termination of the Participant’s employment with the Corporation or its Affiliates;

          (D) Fails to inform any new employer, before accepting employment, of the terms of this

     The Administrator shall determine in its sole discretion whether the Participant has engaged
in any of the acts set forth in (A) through (G) above, and its determination shall be conclusive
and binding on all interested persons.

     Any provision of this Section V which is determined by a court of competent jurisdiction to be
invalid or unenforceable should be construed or limited in a manner that is valid and enforceable
and that comes closest to the business objectives intended by such invalid or unenforceable
provision, without invalidating or rendering unenforceable the remaining provisions of this
Section V.

VI. CHANGE IN CONTROL

     1. If as a result of a Change in Control, the Common Stock ceases to be listed for trading on
a national securities exchange (an “Exchange”), any Option, Restricted Stock Award, Restricted
Stock Unit Award, or Performance Shares that are unvested on the effective date of the Change in
Control shall continue to vest according to the terms and conditions of such Award, provided that
such Award is replaced with an award for voting securities of the resulting corporation or the
acquiring corporation, as the case may be, (including without limitation, the voting securities of
any corporation which as a result of the Change in Control owns the Corporation or all or
substantially all of the Corporation’s assets either directly or through one or more
subsidiaries) (the “Surviving Company”) which are traded on an Exchange (a “Replacement Award”),
which Replacement Award, (i) in the case of Options, shall consist of options with the number of
underlying shares and exercise price determined in a manner consistent with Code
Section 424(a) with vesting and any other terms continuing in the same manner as the replaced
Options; (ii) in the case of Performance Shares, shall consist of restricted stock or restricted
stock units with a value (determined using the Surviving Company’s stock price as of the effective
date of the Change in Control) equal to the value of the Performance Shares (determined using the
Corporation’s stock price and assuming attainment of target performance or actual performance
achieved, if greater, as of the effective date of the Change in Control), with any restrictions on
such restricted stock or restricted stock units lapsing at the end of the measuring period over
which performance for the replaced Performance Shares was to be measured prior to the granting of
the Replacement Award; and (iii) in the case of Restricted Stock or Restricted Stock Unit Awards,
shall consist of restricted stock or restricted stock units with a value (determined using the
Surviving Company’s stock price as of the effective date of the Change in Control) equal to the
value of the Restricted Stock or Restricted Stock Unit Awards (determined using the Corporation’s
stock price as of the effective date of the Change in Control), with any restrictions on such
restricted stock or restricted stock units lapsing at the same time and manner as the replaced
Award; provided, however, that in the event of a termination by the Corporation without Cause or by
the Participant for Good Reason during the vesting period of any Replacement Award, the Replacement
Award shall immediately vest; and provided further that upon the vesting date of each Replacement
Award, in addition to the fully vested Replacement Award, the Participant shall be entitled to
receive a lump sum cash payment equal to the decrease, if any, in the value of a share of the
Surviving Company’s stock from the effective date of the Change in Control (as increased on a
calendar quarterly basis using an

annual interest rate, as of the last business day of the calendar quarter, for zero-coupon
U.S. government securities with a constant maturity closest in length to the time period between
the effective date of the Change in Control and the date of the vesting of the Replacement
Award) to the time of vesting, multiplied by the total number of shares or share equivalents
subject to the options, restricted stock, or restricted stock units in the Replacement Award. If
Options, Restricted Stock Awards, Restricted Stock Unit Awards, or Performance Shares that are
unvested at the effective time of the Change in Control are not replaced with Replacement Awards,
such Awards shall immediately vest and, in the case of Performance Shares, shall vest based upon
deemed attainment of target performance or actual performance achieved, if greater.

     If as a result of a Change in Control, the Common Stock continues to be listed for trading on
an Exchange, any unvested Option, Restricted Stock Award, or Restricted Stock Unit Award shall
continue to vest according to the terms and conditions of such Award and any Performance Shares
shall be replaced with Restricted Stock or Restricted Stock Units where the number of such
Restricted Stock or Restricted Stock Units shall be equal to the number of Performance Shares
assuming attainment of target performance or actual performance achieved, if greater, as of the
effective date of the Change in Control with any restrictions on such Restricted Stock or
Restricted Stock Units lapsing at the end of the measuring period over which performance for the
replaced Performance Shares was to be measured prior to the granting of the replacement Award;
provided however, that, in the event of a termination by the Corporation without Cause or by the
Participant for Good Reason during the vesting period of an Award, such Award shall immediately
vest; and provided further that upon the vesting date of each Award, in addition to the fully
vested Award, the Participant shall be entitled to receive a lump sum cash payment equal to the
decrease, if any, in the value of a Share of the Corporation’s stock from the effective date of the
Change in Control (as increased on a calendar quarterly basis using an annual interest rate, as of
the last business day of the calendar quarter, for zero-coupon U.S. government securities with a
constant maturity closest in length to the time period between the effective date of the Change in
Control and the date of the vesting of the award) to the time of vesting, multiplied by the total
number of Shares or Share Equivalents subject to the Options, Restricted Stock, or Restricted Stock
Units.

     2. For purposes of this Statement of Terms and Conditions, a “Change in Control” of the
Corporation shall be deemed to have occurred if any of the events set forth in any one of the
following paragraphs shall occur:

          (i) Any “person” (as such term is used in Sections 13(d) and 14(d) of the Exchange Act),
excluding the Corporation or any of its Affiliates, a trustee or any fiduciary holding securities
under an employee benefit plan of the Corporation or any of its Affiliates, an underwriter
temporarily holding securities pursuant to an offering of such securities or a Corporation owned,
directly or indirectly, by stockholders of the Corporation in substantially the same proportions as
their ownership of the Corporation, is or becomes the “beneficial owner” (as defined in Rule 13d-3
under the Exchange Act), directly or indirectly, of securities of the Corporation representing 30%
or more of the combined voting power of the Corporation’s then outstanding securities; or

          (ii) During any period of not more than two consecutive years, individuals who at the
beginning of such period constitute the Board and any new director (other than a

12.

 

CEO

director designated by a Person who has entered into an agreement with the Corporation to
effect a transaction described in clause (i), (iii) or (iv) of this paragraph) whose election by
the Board or nomination for election by the Corporation’s stockholders was approved by a vote of at
least two-thirds (2/3) of the directors then still in office who either were directors at the
beginning of the period or whose election or nomination for election was previously so approved,
cease for any reason to constitute a majority thereof; or

          (iii) The shareholders of the Corporation approve a merger or consolidation of the Corporation
with any other Corporation, other than (A) a merger or consolidation which would result in the
voting securities of the Corporation outstanding immediately prior thereto continuing to represent
(either by remaining outstanding or by being converted into voting securities of the surviving
entity), in combination with the ownership of any trustee or other fiduciary holding securities
under an employee benefit plan of the Corporation, at least 50% of the combined voting power of the
voting securities of the Corporation or such surviving entity outstanding immediately after such
merger or consolidation, or (B) a merger or consolidation effected to implement a recapitalization
of the Corporation (or similar transaction) in which no person acquires more than 50% of the
combined voting power of the Corporation’s then outstanding securities; or

          (iv) The shareholders of the Corporation approve a plan of complete liquidation of the
Corporation or an agreement for the sale or disposition by the Corporation of all or substantially
all of the Corporation’s assets.

          Notwithstanding the foregoing, no Change in Control shall be deemed to have occurred if there
is consummated any transaction or series of integrated transactions immediately following which the
holders of the Stock immediately prior to such transaction or series of transactions continue to
have the same proportionate ownership in an entity which owns all or substantially all of the
assets of the Corporation immediately prior to such transaction or series of transactions.

VII. MISCELLANEOUS

     1. No Effect on Terms of Employment. Participation in the Plan shall not create a
right to further employment with the Participant’s employer (the “Employer”) and shall not
interfere with the ability of the Employer to terminate, with or without cause, or change the terms
of employment of a Participant at any time.

     2. Grants to Participants in Foreign Countries. In making grants to Participants in
foreign countries, the Administrator has the full discretion to deviate from this Statement of
Terms and Conditions in order to adjust grants under the Plan to prevailing local conditions,
including custom and legal and tax requirements. Furthermore, the Corporation reserves the right
to impose other requirements on the Participant’s participation in the Plan on the Award and on
any shares acquired under the Plan, to the extent the Corporation determines it is necessary or
advisable in order to comply with local law or facilitate the administration of the Plan, and to
require the Participant to sign any additional agreements or undertaking that may be necessary to
accomplish the foregoing.

13.

 

CEO

     3. Information Notification. Any information required to be given under the terms of
an Award shall be addressed to the Corporation in care of its Corporate Secretary at McKesson
Plaza, One Post Street, San Francisco, California 94104, and any notice to be given to a
Participant shall be addressed to him at the address indicated beneath his name on the Agreement or
such other address as either party may designate in writing to the other. Any such notice shall be
deemed to have been duly given when enclosed in a properly sealed envelope or wrapper addressed as
aforesaid, registered or certified and deposited (postage or registration or certification fee
prepaid) in a post office or branch post office.

     4. Administrator Decisions Conclusive. All decisions of the Administrator
administering the Plan upon any questions arising under the Plan, under this Statement of Terms and
Conditions, or under an Agreement, shall be conclusive.

     5. No Effect on Other Benefit Plans. Nothing herein contained shall affect a
Participant’s right to participate in and receive benefits from and in accordance with the then
current provisions of any pensions, insurance or other employment welfare plan or program offered
by the Corporation.

     6. Withholding. Regardless of any action the Corporation or the Employer takes with
respect to any federal, state or local income tax, social insurance, payroll tax, payment on
account or other tax-related items related to the Participant’s participation in the Plan and
legally applicable to the Participant (“Tax-Related Items”), the Participant acknowledges that the
ultimate liability for all Tax-Related Items is and remains his responsibility and may exceed the
amount actually withheld by the Corporation or the Employer. The Participant further acknowledges
that the Corporation and/or the Employer (1) make no representations or undertakings regarding the
treatment of any Tax-Related Items in connection with any aspect of the Award, including the grant,
vesting or exercise of the Award, as applicable, the subsequent sale of Shares acquired pursuant to
the Plan and the receipt of any dividends and/or dividend equivalents; and (2) do not commit and
are under no obligation to structure the terms of the grant or any aspect of the Award to reduce or
eliminate the Participant’s liability for Tax-Related Items or achieve any particular tax result.
Further, if the Participant has become subject to tax in more than one jurisdiction between the
Grant Date and the date of any relevant taxable event, the Participant acknowledges that the
Corporation and/or the Employer (or former employer, as applicable) may be required to withhold or
account for Tax-Related Items in more than one jurisdiction.

     Prior to any relevant taxable or tax withholding event, as applicable, the Participant will
pay or make adequate arrangements satisfactory to the Corporation and/or the Employer, or their
respective agents, at their discretion, to satisfy the obligations with regard to all Tax-Related
Items by one or a combination of the following: (1) withholding from the Participant’s wages or
other cash compensation paid to him by the Corporation and/or the Employer; (2) withholding from
proceeds of the sale of Shares acquired under the Plan either through a voluntary sale or through a
mandatory sale arranged by the Corporation (on the Participant’s behalf pursuant to this
authorization and any other authorization the Corporation and/or the broker designated by the
Corporation may require the Participant to sign in connection with the sale of Shares); or (3)
withholding Shares to be issued upon grant, vesting/settlement or exercise, as applicable.
Calculation of the number of Shares to be withheld shall be made based on the closing price of

14.

 

CEO

the Common Stock on the New York Stock Exchange on the date that the amount of tax to be
withheld is determined. In no event, however, shall the Corporation be required to issue
fractional shares of Stock. With respect to an Award other than an Option, if adequate
arrangements to satisfy the obligations with regard to all Tax-Related Items are not made by the
Participant with the Corporation and/or the Employer prior to the relevant taxable event, the
Corporation will satisfy such obligations as provided above in (3) of this paragraph.

     To avoid negative accounting treatment, the Corporation may withhold or account for
Tax-Related Items by considering applicable minimum statutory withholding amounts or other
applicable withholding rates. If the obligation for Tax-Related Items is satisfied by withholding
in Shares, for tax purposes, the Participant will be deemed to have been issued the full number of
Shares subject to the Award, notwithstanding that a number of the Shares are held back solely for
the purpose of paying the Tax-Related Items due as a result of any aspect of the Participant’s
participation in the Plan.

     Finally, the Participant shall pay to the Corporation or the Employer any amount of
Tax-Related Items that the Corporation or the Employer may be required to withhold or account for
as a result of the Participant’s participation in the Plan that cannot be satisfied by the means
previously described. The Corporation may refuse to issue or deliver the Shares or the proceeds of
the sale of Shares if the Participant fails to comply with his obligations in connection with the
Tax-Related Items.

     The Administrator shall be authorized to establish such rules, forms and procedures as it
deems necessary to implement the foregoing.

     7. Successors. This Statement of Terms and Conditions and the Award Agreements shall
be binding upon and inure to the benefit of any successor or successors of the Corporation.
“Participant” as used herein shall include the Participant’s Beneficiary.

     8. Delaware Law. The interpretation, performance, and enforcement of this Statement
of Terms and Conditions and all Award Agreements shall be governed by the laws of the State of
Delaware.

     9. Data Privacy. By accepting the Award, the Participant hereby explicitly and
unambiguously consents to the collection, use and transfer, in electronic or other form, of his
personal data as described in this document by and among, as applicable, the Employer and the
Corporation and its Affiliates for the exclusive purpose of implementing, administering and
managing participation in the Plan.

          The Participant understands that the Corporation and the Employer hold certain personal
information about the Participant, including, but not limited, his name, home address and telephone
number, date of birth, social insurance or other identification number, salary, nationality, job
title, any Shares or directorships held in the Corporation, details of all Options, Restricted
Stock, Restricted Stock Units, Performance Shares, Other Share-Based Awards, or any other
entitlement to Shares of stock awarded, canceled, exercised, vested, unvested or outstanding in the
Participant’s favor, for the purpose of implementing, administering and managing the Plan (“Data”).
The Participant understands that Data may be transferred to any

15.

 

CEO

third parties assisting in the implementation, administration and management of the Plan, that
these recipients may be located in the Participant’s country or elsewhere, such as in the United
States of America, and that the recipient’s country may have different data privacy laws and
protections than the Participant’s country. The Participant understands that he or she may request
a list with the names and addresses of any potential recipients of the Data by contacting the local
human resources representative. The Participant authorizes the recipients to receive, possess,
use, retain and transfer the Data, in electronic or other form, for the purposes of implementing,
administering and managing participation in the Plan, including any requisite transfer of such Data
as may be required to a broker or other third party with whom the Participant may elect to deposit
any Shares of stock acquired under the Plan. The Participant understands that Data will be held
only as long as is necessary to implement, administer and manage his participation in the Plan.
The Participant understands that he or she may, at any time, view Data, request additional
information about the storage and processing of Data, require any necessary amendments to Data or
refuse or withdraw the consents herein, without cost, by contacting in writing the local human
resources representative. The Participant understands, however, that refusing or withdrawing
consent may affect his ability to participate in the Plan. For more information on the
consequences of refusal to consent or withdrawal of consent, the Participant understands that he or
she may contact the local human resources representative.

PURSUANT TO THE 2005 STOCK PLAN

(Effective as of April 20, 2010)

I. INTRODUCTION

     The following terms and conditions shall apply to an Award granted under the Plan. This
Statement of Terms and Conditions is intended to meet the requirements of Code Section 409A and any
rules promulgated thereunder and is subject to the terms and conditions of the Plan. In the event
of any inconsistency between this Statement of Terms and Conditions and the Plan, the Plan shall
govern. Capitalized terms not otherwise defined in this Statement of Terms and Conditions shall
have the meaning set forth in the Plan.

II. OPTIONS

     1. Option Notice and Agreement. An Option granted under the Plan shall be evidenced
by an Option Agreement setting forth the terms and conditions of the Option, including whether the
Option is an Incentive Stock Option or a Nonstatutory Stock Option and the number Shares subject to
the Option. Each Option Agreement shall incorporate by reference and be subject to this Statement
of Terms and Conditions and the terms and conditions of the Plan.

     2. Exercise Price. The per Share Exercise Price of an Option, as specified in the
Option Agreement, shall be equal to or greater than the per Share Fair Market Value of the Shares
underlying the Option on the Grant Date.

     3. Option Period. An Option shall be exercisable only during the applicable Option
Period, and during such Option Period the exercisability of the Option shall be subject to the
vesting provisions of Section II.4 as modified by the rules set forth in Sections II.5 and V. The
Option Period shall be not more than seven years from the Grant Date.

     4. Vesting of Right to Exercise Options.

          (A) Except as provided in Section V, an Option shall be exercisable during the Option Period
in accordance with the following vesting schedule: (i) 25% of the Shares subject to the Option
shall vest on the first anniversary of the Grant Date; (ii) an additional 25% of the Shares shall
vest on the second anniversary of the Grant Date; (iii) an additional 25% of the Shares shall vest
on the third anniversary of the Grant Date; and (iv) the remaining 25% of the Shares subject to the
Option shall vest on the fourth anniversary of the Grant Date. Notwithstanding the foregoing, the
Administrator may specify a different vesting schedule at the time the Option is granted, which

1.

 

Officers

          (B) Any vested portion of an Option not exercised hereunder shall accumulate and be
exercisable at any time on or before the Termination Date, subject to the rules set forth in
Section V. No Option may be exercised for less than 5% of the total number of Shares then
available for exercise under such Option. In no event shall the Corporation be required to issue
fractional Shares.

     5. Limits on Option Period and Acceleration of Vesting. The Option Period may end
before the Termination Date, and in the circumstances described in Sections II.5(B), (D), (E) and
(F), the vesting schedule of an Option may be accelerated, (subject to the provisions of
Section V), as follows:

          (A) If a Participant ceases to be a bona fide employee of the Corporation or of its Affiliates
during the Option Period for reasons other than for Cause (as defined herein), Long-Term
Disability, Normal or Early Retirement or death, the Option Period shall end ninety days after the
date of the Participant’s termination of employment or on the Termination Date, whichever occurs
first and in all cases the Option shall be exercisable only to the extent that it was exercisable
under the provisions of the foregoing Section II.4 at the time of such termination of employment.
If a Participant is absent from work with the Corporation or an Affiliate because of his or her
Short-Term Disability or because the Participant is on an approved leave of absence, the
Participant shall not be deemed during the period of any such absence, by virtue of such absence
alone, to have terminated employment with the Corporation or an Affiliate except as the
Administrator may otherwise expressly determine. Notwithstanding the foregoing, if the Participant
is on a voluntarily leave of absence for the purpose of serving the government of the country of
which the Participant is a citizen or in which the Participant’s principal place of employment is
located and such leave exceeds twelve months in duration, then the Participant shall be deemed to
have terminated employment with the Corporation or an Affiliate for purposes of this
Section II.5(A).

          (B) If a Participant ceases to be a bona fide employee of the Corporation or of its Affiliates
(for reasons other than for Cause, Long-Term Disability, Normal or Early Retirement or
death) during the Option Period, the Administrator may, in its sole and absolute discretion (and
subject to conditions deemed appropriate in the circumstances) approve the continuation of the
vesting schedule of the Participant’s Option. The Option Period for any Option that continues to
vest pursuant to this subsection (B) shall end ninety days after the last Option installment vests,
or on the Termination Date, whichever occurs first.

          (C) If the Participant’s employment is terminated for Cause during the Option Period, the
Option Period shall end on the date of such termination of employment and the Option shall
thereupon not be exercisable to any extent whatsoever.

          (D) If a Participant ceases to be a bona fide employee of the Corporation or of its Affiliates
due to his or her Long-Term Disability during the Option Period, the vesting schedule of the
Participant’s Option shall be accelerated, the Option shall become fully exercisable and the Option
Period shall end three years after the date of the Participant’s termination of employment or on
the Termination Date, whichever occurs first.

          (E) If the Participant’s employment is terminated:

2.

 

Officers

               (i) by reason of Normal Retirement, the vesting schedule of the Participant’s Option shall be
accelerated and the Option shall become fully exercisable as of the date of Normal Retirement; or

               (ii) by reason of Early Retirement, the Option shall be exercisable only to the extent that it
was exercisable under the provisions of the foregoing Section II.4 at the time of such Early
Retirement; provided, however, that the Administrator may, in its sole discretion (and subject to
conditions deemed appropriate in the circumstances), either (A) accelerate the vesting schedule of
the Participant’s Option effective as of the date of the Participant’s Early Retirement or
(B) approve the continuation of the vesting schedule of the Participant’s Option.

               (iii) With respect to an Option held by a Participant at Normal or Early Retirement, the
Option Period for that portion of the Option designated as a Nonstatutory Stock Option shall end
three years after the date of retirement or on the Termination Date, whichever occurs first;
provided, however, that in the case of an Option held by a Participant at Early Retirement as to
which the Administrator exercises its discretionary authority to approve the continuation of the
vesting schedule, the Option Period shall end on the earlier of the Termination Date or three years
after the last Option installment vests.

          (F) If a Participant should die while in the employ of the Corporation or an Affiliate and
during the Option Period, the vesting schedule of the Participant’s Option shall be accelerated and
the Option shall become fully exercisable, the Option Period shall end three years after the date
of death or on the Termination Date, whichever occurs first, and the Participant’s Beneficiary may
exercise the entire unexercised portion of the then exercisable Shares covered by such Option (or
any lesser amount) remaining on the date of death.

          (G) If a Participant who ceases to be a bona fide employee of the Corporation or an Affiliate
is subsequently rehired prior to the expiration of his or her Option, then the Option shall
continue to remain outstanding until such time as the Participant subsequently terminates
employment. Upon the Participant’s subsequent termination of employment, the post-termination
exercise period calculated pursuant to the terms and conditions of this Section II.5 shall be
reduced by the number of days between the date of the Participant’s initial termination of
employment and his or her re-hire date; provided, however, that if the rehired Participant
continues to be employed by the Corporation or an Affiliate for at least one year from his or her
rehire date, then the post termination exercise period for the Option shall be determined in
accordance with Sections II.5(A) through (F) and shall not be adjusted as described above.

     6. Method of Exercise. A Participant may exercise an Option with respect to all or
any part of the exercisable Shares as follows:

          (A) By giving the Corporation, or its authorized representative designated for this purpose,
written notice of such exercise specifying the number of Shares as to which the Option is so
exercised. Such notice shall be accompanied by an amount equal to the Exercise Price of such
Shares, in the form of any one or combination of the following: cash or a certified check, bank
draft, postal or express money order payable to the order of the Corporation in lawful money of the
United States. Unless otherwise determined by the Administrator in his or

3.

 

Officers

her sole discretion, the Participant may pay the Exercise Price, in whole or in part, by
tendering to the Corporation or its authorized representative Shares which have been owned by the
Participant for at least six months prior to said tender, and having a fair market value, as
determined by the Corporation, equal to the Exercise Price, or in lieu of the delivery of actual
Shares in such tender, the Corporation may accept an attestation by the Participant, in a form
prescribed by the Corporation or its authorized representative, that the Participant owns
sufficient Shares of record or in an account in street name to satisfy the Exercise Price, and such
attestation will be deemed a tender of Shares for purposes of this method of exercise. In the
event a Participant tenders Shares to pay the Exercise Price, tender of Shares acquired through
exercise of an Incentive Stock Option may result in unfavorable income tax consequences unless such
Shares are held for at least two years from the Grant Date of the Incentive Stock Option and one
year from the date of exercise of the Incentive Stock Option. The Corporation or its authorized
representative may accept payment of the Exercise Price in the form of a Participant’s personal
check. Payment may also be made by delivery (including by FAX transmission) to the Corporation or
its authorized representative of an executed irrevocable Option exercise form together with
irrevocable instructions to an approved registered investment broker to sell Shares in an amount
sufficient to pay the Exercise Price plus any applicable withholding taxes and to transfer the
proceeds of such sale to the Corporation.

          (B) If required by the Corporation, by giving satisfactory assurance in writing, signed by the
Participant, the Participant shall give his or her assurance that the Shares subject to the Option
are being purchased for investment and not with a view to the distribution thereof; provided that
such assurance shall be deemed inapplicable to (1) any sale of the Shares by such Participant made
in accordance with the terms of a registration statement covering such sale, which has heretofore
been (or may hereafter be) filed and become effective under the U.S. Securities Act of 1933, as
amended (the “Securities Act”) and with respect to which no stop order suspending the effectiveness
thereof has been issued, and (2) any other sale of the Shares with respect to which, in the opinion
of counsel for the Corporation, such assurance is not required to be given in order to comply with
the provisions of the Securities Act.

          (C) As soon as practicable after receipt of the notice and the assurance described in
Sections II.6(A) and (B), the Corporation shall, without transfer or issue tax (except for
withholding tax arrangements contemplated in Section VII.6) and without other incidental expense to
the Participant, cause an appropriate book entry to be entered in the records of the Corporation’s
transfer agent recording the Participant’s unrestricted interest in the purchased Shares; provided,
however, that the time of such delivery may be postponed by the Corporation for such period as may
be required for it with reasonable diligence to comply with applicable registration requirements
under the Securities Act, the Exchange Act, any applicable listing requirements of any national
securities exchange and requirements under any other law or regulation applicable to the issuance
or transfer of the Shares.

     7. Limitations on Transfer. An Option shall, during a Participant’s lifetime, be
exercisable only by the Participant. No Option or any right granted thereunder shall be
transferable by the Participant by operation of law or otherwise, other than by will or the laws of
descent and distribution. Notwithstanding the foregoing, (i) a Participant may designate a
beneficiary to succeed, after the Participant’s death, to all of the Participant’s Options
outstanding on the date of death; (ii) a Nonstatutory Stock Option may be transferable pursuant

4.

 

Officers

to a qualified domestic relations order as defined in the Code or Title I of the U.S. Employee
Retirement Income Security Act; and (iii) any Participant, who is a senior executive officer
recommended by the Chief Executive Officer of the Corporation and approved by the Administrator may
voluntarily transfer any Nonstatutory Stock Option to a Family Member as a gift or through a
transfer to an entity in which more than 50% of the voting interests are owned by Family Members
(or the Participant) in exchange for an interest in that entity. In the event of any attempt by a
Participant to alienate, assign, pledge, hypothecate, or otherwise dispose of an Option or of any
right thereunder, except as provided herein, or in the event of the levy of any attachment,
execution, or similar process upon the rights or interest hereby conferred, the Corporation at its
election may terminate the affected Option by notice to the Participant and the Option shall
thereupon become null and void.

     8. No Shareholder Rights. Neither a Participant nor any person entitled to exercise a
Participant’s rights in the event of the Participant’s death shall have any of the rights of a
shareholder with respect to the Shares subject to an Option except to the extent that a book entry
has been entered in the records of the Corporation’s transfer agent with respect to such Shares
upon the exercise of an Option.

III. RESTRICTED STOCK

     1. Restricted Stock Agreement. A Restricted Stock Award granted under the Plan shall
be evidenced by a Restricted Stock Agreement to be executed by the Participant and the Corporation
setting forth the terms and conditions of the Restricted Stock Award. Each Restricted Stock
Agreement shall incorporate by reference and be subject to this Statement of Terms and Conditions
and the terms and conditions of the Plan.

     2. Rights with Respect to Shares of Restricted Stock. Upon written acceptance of a
grant of Restricted Stock Award by a Participant, including the restrictions and other terms and
conditions described in the Plan, the Restricted Stock Agreement and herein, the Corporation shall
cause an appropriate book entry to be entered in the records of the Corporation’s transfer agent
recording the Participant’s interest in the Restricted Stock. From and after the Grant Date, the
Participant shall have absolute ownership of such Shares of Restricted Stock, including the right
to vote and to receive dividends thereon, subject to the terms, conditions and restrictions
described in the Plan, the Restricted Stock Agreement and this Statement of Terms and Conditions.

     3. Special Restrictions. Each Restricted Stock Award made under the Plan shall
contain the following terms, conditions and restrictions and such additional terms, conditions and
restrictions as may be determined by the Administrator; provided, however, that no Restricted Stock
grant shall be subject to additional terms, conditions and restrictions which are more favorable to
a Participant than the terms, conditions and restrictions set forth elsewhere in the Plan, the
Restricted Stock Agreement or this Statement of Terms and Conditions.

          (A) Restrictions. Until the restrictions imposed on any Restricted Stock grant shall
lapse, Shares of Restricted Stock granted to a Participant: (i) shall not be sold, assigned,
transferred, pledged, hypothecated, or otherwise disposed of, other than pursuant to a qualified
domestic relations order as defined in the Code or Title I of the U.S. Employee Retirement

5.

 

Officers

Income Security Act and (ii) shall, if the Participant’s continuous employment with the
Corporation or any of its Affiliates shall terminate for any reason (except as otherwise provided
in the Plan or in Section III.3(B)) be returned to the Corporation forthwith, and all the rights of
the Participant to such Shares shall immediately terminate. If a Participant is absent from work
with the Corporation or an Affiliate because of his or her Short-Term Disability or because the
Participant is on an approved leave of absence, the Participant shall not be deemed during the
period of any such absence, by virtue of such absence alone, to have terminated employment with the
Corporation or an Affiliate except as the Administrator may otherwise expressly determine.
Notwithstanding the foregoing, if the Participant is on a voluntarily leave of absence for the
purpose of serving the government of the country of which the Participant is a citizen or in which
the Participant’s principal place of employment is located and such leave exceeds twelve months in
duration, then the Participant shall be deemed to have terminated employment with the Corporation
or an Affiliate for purposes of this Section III.3(A).

          (B) Termination of Employment by Reason of Death, Long-Term Disability or Normal
Retirement. Notwithstanding any provision contained herein or in the Plan or the Restricted
Stock Agreement to the contrary, if a Participant who has been in the continuous employment of the
Corporation or any of its Affiliates since the Grant Date of a Restricted Stock Award ceases to be
a bona fide employee of the Corporation or an Affiliate as a result of death, Long-Term Disability,
or Normal Retirement, then the restrictions imposed on any Restricted Stock Award shall lapse as to
all Shares granted to such Participant pursuant to such Restricted Stock Award on the date of such
termination.

          (C) Termination of Employment by Reason of Early Retirement. Notwithstanding any
provision contained herein or in the Plan or the Restricted Stock Agreement to the contrary, if a
Participant who has been in the continuous employment of the Corporation or any of its Affiliates
since the Grant Date of a Restricted Stock Award ceases to be a bona fide employee of the
Corporation or an Affiliate by reason of Early Retirement, the Administrator may, in its sole
discretion (and subject to conditions deemed appropriate in the circumstances), accelerate the
vesting schedule of the Participant’s Restricted Stock Award effective as of the date of the
Participant’s Early Retirement.

          (D) Restriction on Sale. The Compensation Committee reserves the right to impose a
restriction on the sale of Shares that the Participant receives upon the vesting and settlement of
a Restricted Stock Award, unless the Participant has satisfied the ownership targets applicable to
the Participant as provided in the Stock Ownership Policy.

     4. Dividends. Cash dividends paid with respect to the Restricted Stock during the
Restriction Period shall be paid directly to the Participant during the Restriction Period. Stock
dividends paid with respect to Restricted Stock during the Restriction Period shall be treated as
Restricted Stock which shall be subject to the same restrictions as the original award for the
duration of the Restricted Period.

     5. Election to Recognize Gross Income in the Year of Grant. If any Participant
validly elects within thirty days of the Grant Date, to include in gross income for federal income
tax purposes an amount equal to the fair market value of the Shares of Restricted Stock granted on
the Grant Date, such Participant shall pay to the Corporation, or make arrangements

6.

 

Officers

satisfactory to the Administrator to pay to the Corporation in the year of such grant, any
federal, state or local taxes required to be withheld with respect to such Shares in accordance
with Section VII.6.

     6. Restrictive Legend. Each book entry in the records of the Corporation’s transfer
agent evidencing Shares granted pursuant to a Restricted Stock grant may bear an appropriate legend
referring to the terms, conditions and restrictions described in the Plan, the Restricted Stock
Agreement and this Statement of Terms and Conditions.

     7. Expiration of Restricted Period. If and when the Restriction Period applicable to
the Restricted Stock expires without a prior forfeiture, an appropriate book entry recording the
Participant’s interest in the unrestricted Shares shall be entered on the records of the
Corporation’s transfer agent.

IV. RESTRICTED STOCK UNITS AND PERFORMANCE SHARES

     1. Award Agreement.

          (A) A Restricted Stock Unit Award granted under the Plan shall be evidenced by a Restricted
Stock Unit Agreement to be executed by the Participant and the Corporation setting forth the terms
and conditions of the Restricted Stock Unit Award. Each Restricted Stock Unit Agreement shall
incorporate by reference and be subject to this Statement of Terms and Conditions and the terms and
conditions of the Plan.

          (B) Performance Shares granted under the Plan shall be evidenced by a Performance Share
Agreement to be executed by the Participant and the Corporation setting forth the terms and
conditions of the Performance Shares. Each Performance Share Agreement shall incorporate by
reference and be subject to this Statement of Terms and Conditions and the terms and conditions of
the Plan.

     2. Special Restrictions. Restricted Stock Unit Awards and Performance Shares granted
under the Plan shall contain the following terms, conditions and restrictions and such additional
terms, conditions and restrictions as may be determined by the Administrator; provided, however,
that no such Award shall be subject to additional terms, conditions and restrictions which are more
favorable to a Participant than the terms, conditions and restrictions set forth elsewhere in the
Plan, the Restricted Stock Unit Agreement or Performance Share Agreement or this Statement of Terms
and Conditions.

          (A) Restrictions. If a Participant ceases to be a bona fide employee of the
Corporation or an Affiliates (except as otherwise provided in the Plan or in Section III.3(B) or
(C)) prior to the lapse of the restrictions imposed on the Award, the unvested Restricted Stock
Units or Performance Shares shall be returned to the Corporation, and all the rights of the
Participant to such Share Equivalents shall immediately terminate. If a Participant is absent from
work with the Corporation or an Affiliate because of his or her Short-Term Disability or because
the Participant is on an approved leave of absence, the Participant shall not be deemed during the
period of any such absence, by virtue of such absence alone, to have terminated employment with the
Corporation or an Affiliate except as the Administrator may otherwise expressly determine.
Notwithstanding the foregoing, if the Participant is on a voluntarily leave of absence

7.

 

Officers

for the purpose of serving the government of the country of which the Participant is a citizen
or in which the Participant’s principal place of employment is located and such leave exceeds
twelve months in duration, then the Participant shall be deemed to have terminated employment with
the Corporation or an Affiliate for purposes of this Section IV.2(A).

          (B) Termination of Employment by Reason of Death, Long-Term Disability or Normal
Retirement. Notwithstanding any provision contained herein or in the Plan, the Restricted
Stock Unit Agreement or Performance Share Agreement to the contrary, if a Participant who has been
in the continuous employment of the Corporation or any of its Affiliates since the Grant Date
shall, while in such employment, be terminated as a result of death, Long-Term Disability, or
Normal Retirement, then the restrictions imposed on any Restricted Stock Unit Award or Performance
Shares shall lapse as to all Share Equivalents granted to such Participant pursuant to such Award
on the date of such termination.

          (C) Termination of Employment by Reason of Early Retirement. Notwithstanding any
provision contained herein or in the Plan or the Restricted Stock Unit Agreement or Performance
Share Agreement to the contrary, if a Participant who has been in continuous employment of the
Corporation or any of its Affiliates since the Grant Date of a Restricted Stock Unit Award or
Performance Share Award ceases to be a bona fide employee of the Corporation or an Affiliate by
reason of Early Retirement, the Administrator may, in its sole discretion (and subject to
conditions deemed appropriate in the circumstances), accelerate the vesting schedule of the
Participant’s Restricted Stock Units or Performance Shares effective as of the date of the
Participant’s Early Retirement.

          (D) Restriction on Sale. The Compensation Committee reserves the right to impose a
restriction on the sale of Shares that the Participant receives upon the settlement of a Restricted
Stock Unit Award, unless the Participant has satisfied the ownership targets applicable to the
Participant as provided in the Stock Ownership Policy.

     3. Dividend Equivalents. Dividend equivalents shall be credited in respect of
Restricted Stock Units and Performance Shares. Cash dividends shall be credited on behalf of the
Participant to a deferred cash account (in a manner designed to comply with Code Section 409A).
Stock dividends shall be converted into additional Restricted Stock Units or Performance Shares,
which will be subject to all of the terms and conditions of the underlying Restricted Stock Unit
Award or Performance Shares, including the same vesting restrictions as the underlying award.

     4. Assignability. A Participant shall not be permitted to sell, transfer, pledge,
assign or encumber Restricted Stock Units or Performance Shares, other than pursuant to a qualified
domestic relations order as defined in the Code or Title I of the U.S. Employee Retirement Income
Security Act.

     5. No Shareholder Rights. Neither a Participant nor any person entitled to exercise a
Participant’s rights in the event of the Participant’s death shall have any of the rights of a
shareholder with respect to the Share Equivalents subject to a Restricted Stock Unit Award or
Performance Shares except to the extent that a book entry has been entered in the records of the

8.

 

Officers

Corporation’s transfer agent with respect to such Shares upon the settlement of any vested
Restricted Stock Unit Award of Performance Shares.

     6. Time of Payment of Restricted Stock Units and Performance Shares. Upon the lapse
of the restriction imposed on Restricted Stock Unit Awards or Performance Shares, all Restricted
Stock Units and Performance Shares that were not forfeited pursuant to Sections IV.2(A) or V shall
be paid to the Participant as soon as reasonably practicable after the restrictions lapse. Payment
shall be made in Shares in the form of a an appropriate book entry entered in the records of the
Corporation’s transfer agent recording the Participant’s unrestricted interest in the number of
Shares equal to the number of vested Share Equivalents subject to the Restricted Stock Unit Award
or Performance Shares. The foregoing notwithstanding, the Participant may elect to defer payment
of the Restricted Stock Units in the manner described in Section IV.7.

     7. Deferral Election. Each Participant, pursuant to rules established by the
Administrator, may be eligible to elect to defer all or a percentage of any payment in respect of a
Restricted Stock Unit Award that he or she may be entitled to receive as determined pursuant to
Section IV.6. This election shall be made by giving notice in a manner and within the time
prescribed by the Administrator and in compliance with Code Section 409A. If a deferral is
permitted, the Participant must indicate the percentage (expressed in whole percentages) he or she
chooses to defer of any payment he or she may be entitled to receive. If no notice is given, the
Participant shall be deemed to have made no deferral election. Each deferral election filed with
the Corporation shall become irrevocable in accordance with the terms and conditions of the
Corporation’s Deferred Compensation Administration Plan III (DCAP III) (or any successor plan) and
in compliance with Code Section 409A.

V. SPECIAL FORFEITURE AND REPAYMENT RULES

     Any other provision of this Statement of Terms and Conditions to the contrary notwithstanding,
if the Administrator determines that a Participant has engaged in any of the actions described in 3
below, the consequences set forth in 1 and 2 below shall result:

     1. Any outstanding Option shall immediately and automatically terminate, be forfeited and
shall cease to be exercisable, without limitation. In addition, any Shares of Restricted Stock,
Restricted Stock Units or Performance Shares as to which the restrictions have not lapsed shall
immediately and automatically be forfeited and such Shares or Share Equivalents shall be returned
to the Corporation and all of the rights of the Participant to such Shares or Share Equivalents
shall immediately terminate.

     2. If the Participant exercised an Option within twelve months prior to the date upon which
the Corporation discovered that the Participant engaged in any actions described in 3 below, the
Participant, upon written notice from the Corporation, shall immediately pay to the Corporation the
economic value realized or obtained by the exercise of such Option measured at the date of
exercise. In addition, if the restrictions imposed on any grant of Restricted Stock, Restricted
Stock Units or Performance Shares lapsed within twelve months prior to the date the Corporation
discovered that the Participant engaged in any action described in 3 below, the Participant, upon
written notice from the Corporation, shall immediately pay to the Corporation

9.

 

Officers

the economic value realized or obtained with respect to such Shares of Restricted Stock, the
Restricted Stock Units or the Performance Shares, measured at the date such Shares or Share
Equivalents vested.

     3. The consequences described in 1 and 2 above shall apply if the Participant, either before
or after termination of employment with the Corporation or its Affiliates:

          (A) Discloses to others, or takes or uses for his own purpose or the purpose of others, any
trade secrets, confidential information, knowledge, data or know-how or any other proprietary
information or intellectual property belonging to the Corporation or its Affiliates and obtained by
the Participant during the term of his employment, whether or not they are the Participant’s work
product. Examples of such confidential information or trade secrets include, without limitation,
customer lists, supplier lists, pricing and cost data, computer programs, delivery routes,
advertising plans, wage and salary data, financial information, research and development plans,
processes, equipment, product information and all other types and categories of information as to
which the Participant knows or has reason to know that the Corporation or its Affiliates intends or
expects secrecy to be maintained;

          (B) Fails to promptly return all documents and other tangible items belonging to the
Corporation or its Affiliates in the Participant’s possession or control, including all complete or
partial copies, recordings, abstracts, notes or reproductions of any kind made from or about such
documents or information contained therein, upon termination of employment, whether pursuant to
retirement or otherwise;

          (C) Fails to provide the Corporation with at least thirty (30) days’ written notice prior to
directly or indirectly engaging in, becoming employed by, or rendering services, advice or
assistance to any business in competition with the Corporation or its Affiliates. As used herein,
“business in competition” means any person, organization or enterprise which is engaged in or is
about to become engaged in any line of business engaged in by the Corporation or its Affiliates at
the time of the termination of the Participant’s employment with the Corporation or its Affiliates;

          (D) Fails to inform any new employer, before accepting employment, of the terms of this
paragraph and of the Participant’s continuing obligation to maintain the confidentiality of the
trade secrets and other confidential information belonging to the Corporation or its Affiliates and
obtained by the Participant during the term of his employment with the Corporation or any of its
Affiliates;

          (E) Induces or attempts to induce, directly or indirectly, any of the customers of the
Corporation or its Affiliates, employees, representatives or consultants to terminate, discontinue
or cease working with or for the Corporation or its Affiliates, or to breach any contract with the
Corporation or any of its Affiliates, in order to work with or for, or enter into a contract with,
the Participant or any third party; or

          (F) Engages in conduct which is not in good faith and which disrupts, damages, impairs or
interferes with the business, reputation or employees of the Corporation or its Affiliates;

10.

 

Officers

          (G) Directly or indirectly engages in, becomes employed by, or renders services, advice or
assistance to any business in competition with the Corporation or its Affiliates, at any time
during the twelve months following termination of employment with the Corporation.

     The Administrator shall determine in its sole discretion whether the Participant has engaged
in any of the acts set forth in (A) through (G) above, and its determination shall be conclusive
and binding on all interested persons.

     Any provision of this Section V which is determined by a court of competent jurisdiction to be
invalid or unenforceable should be construed or limited in a manner that is valid and enforceable
and that comes closest to the business objectives intended by such invalid or unenforceable
provision, without invalidating or rendering unenforceable the remaining provisions of this
Section V.

VI. CHANGE IN CONTROL

     1. If as a result of a Change in Control, the Common Stock ceases to be listed for trading on
a national securities exchange (an “Exchange”), any Option, Restricted Stock Award, Restricted
Stock Unit Award, or Performance Shares that are unvested on the effective date of the Change in
Control shall continue to vest according to the terms and conditions of such Award, provided that
such Award is replaced with an award for voting securities of the resulting corporation or the
acquiring corporation, as the case may be, (including without limitation, the voting securities of
any corporation which as a result of the Change in Control owns the Corporation or all or
substantially all of the Corporation’s assets either directly or through one or more
subsidiaries) (the “Surviving Company”) which are traded on an Exchange (a “Replacement Award”),
which Replacement Award, (i) in the case of Options, shall consist of options with the number of
underlying shares and exercise price determined in a manner consistent with Code
Section 424(a) with vesting and any other terms continuing in the same manner as the replaced
Options; (ii) in the case of Performance Shares, shall consist of restricted stock or restricted
stock units with a value (determined using the Surviving Company’s stock price as of the effective
date of the Change in Control) equal to the value of the Performance Shares (determined using the
Corporation’s stock price and assuming attainment of target performance or actual performance
achieved, if greater, as of the effective date of the Change in Control), with any restrictions on
such restricted stock or restricted stock units lapsing at the end of the measuring period over
which performance for the replaced Performance Shares was to be measured prior to the granting of
the Replacement Award; and (iii) in the case of Restricted Stock or Restricted Stock Unit Awards,
shall consist of restricted stock or restricted stock units with a value (determined using the
Surviving Company’s stock price as of the effective date of the Change in Control) equal to the
value of the Restricted Stock or Restricted Stock Unit Awards (determined using the Corporation’s
stock price as of the effective date of the Change in Control), with any restrictions on such
restricted stock or restricted stock units lapsing at the same time and manner as the replaced
Award; provided, however, that in the event of a termination by the Corporation without Cause or by
the Participant for Good Reason during the vesting period of any Replacement Award, the Replacement
Award shall immediately vest; and provided further that upon the vesting date of each Replacement
Award, in addition to the fully vested Replacement Award, the Participant shall be entitled to
receive a lump sum cash payment

11.

 

Officers

equal to the decrease, if any, in the value of a share of the Surviving Company’s stock from
the effective date of the Change in Control (as increased on a calendar quarterly basis using an
annual interest rate, as of the last business day of the calendar quarter, for zero-coupon U.S.
government securities with a constant maturity closest in length to the time period between the
effective date of the Change in Control and the date of the vesting of the Replacement Award) to
the time of vesting, multiplied by the total number of shares or share equivalents subject to the
options, restricted stock, or restricted stock units in the Replacement Award. If Options,
Restricted Stock Awards, Restricted Stock Unit Awards, or Performance Shares that are unvested at
the effective time of the Change in Control are not replaced with Replacement Awards, such Awards
shall immediately vest and, in the case of Performance Shares, shall vest based upon deemed
attainment of target performance or actual performance achieved, if greater.

     If as a result of a Change in Control, the Common Stock continues to be listed for trading on
an Exchange, any unvested Option, Restricted Stock Award, or Restricted Stock Unit Award shall
continue to vest according to the terms and conditions of such Award and any Performance Shares
shall be replaced with Restricted Stock or Restricted Stock Units where the number of such
Restricted Stock or Restricted Stock Units shall be equal to the number of Performance Shares
assuming attainment of target performance or actual performance achieved, if greater, as of the
effective date of the Change in Control with any restrictions on such Restricted Stock or
Restricted Stock Units lapsing at the end of the measuring period over which performance for the
replaced Performance Shares was to be measured prior to the granting of the replacement Award;
provided however, that, in the event of a termination by the Corporation without Cause or by the
Participant for Good Reason during the vesting period of an Award, such Award shall immediately
vest; and provided further that upon the vesting date of each Award, in addition to the fully
vested Award, the Participant shall be entitled to receive a lump sum cash payment equal to the
decrease, if any, in the value of a Share of the Corporation’s stock from the effective date of the
Change in Control (as increased on a calendar quarterly basis using an annual interest rate, as of
the last business day of the calendar quarter, for zero-coupon U.S. government securities with a
constant maturity closest in length to the time period between the effective date of the Change in
Control and the date of the vesting of the award) to the time of vesting, multiplied by the total
number of Shares or Share Equivalents subject to the Options, Restricted Stock, or Restricted Stock
Units.

     2. For purposes of this Statement of Terms and Conditions, a “Change in Control” of the
Corporation shall be deemed to have occurred if any of the events set forth in any one of the
following paragraphs shall occur:

          (i) Any “person” (as such term is used in Sections 13(d) and 14(d) of the Exchange Act),
excluding the Corporation or any of its Affiliates, a trustee or any fiduciary holding securities
under an employee benefit plan of the Corporation or any of its Affiliates, an underwriter
temporarily holding securities pursuant to an offering of such securities or a Corporation owned,
directly or indirectly, by stockholders of the Corporation in substantially the same proportions as
their ownership of the Corporation, is or becomes the “beneficial owner” (as defined in Rule 13d-3
under the Exchange Act), directly or indirectly, of securities of the Corporation representing 30%
or more of the combined voting power of the Corporation’s then outstanding securities; or

12.

 

Officers

          (ii) During any period of not more than two consecutive years, individuals who at the
beginning of such period constitute the Board and any new director (other than a director
designated by a Person who has entered into an agreement with the Corporation to effect a
transaction described in clause (i), (iii) or (iv) of this paragraph) whose election by the Board
or nomination for election by the Corporation’s stockholders was approved by a vote of at least
two-thirds (2/3) of the directors then still in office who either were directors at the beginning
of the period or whose election or nomination for election was previously so approved, cease for
any reason to constitute a majority thereof; or

          (iii) The shareholders of the Corporation approve a merger or consolidation of the Corporation
with any other Corporation, other than (A) a merger or consolidation which would result in the
voting securities of the Corporation outstanding immediately prior thereto continuing to represent
(either by remaining outstanding or by being converted into voting securities of the surviving
entity), in combination with the ownership of any trustee or other fiduciary holding securities
under an employee benefit plan of the Corporation, at least 50% of the combined voting power of the
voting securities of the Corporation or such surviving entity outstanding immediately after such
merger or consolidation, or (B) a merger or consolidation effected to implement a recapitalization
of the Corporation (or similar transaction) in which no person acquires more than 50% of the
combined voting power of the Corporation’s then outstanding securities; or

          (iv) The shareholders of the Corporation approve a plan of complete liquidation of the
Corporation or an agreement for the sale or disposition by the Corporation of all or substantially
all of the Corporation’s assets.

     Notwithstanding the foregoing, no Change in Control shall be deemed to have occurred if there
is consummated any transaction or series of integrated transactions immediately following which the
holders of the Stock immediately prior to such transaction or series of transactions continue to
have the same proportionate ownership in an entity which owns all or substantially all of the
assets of the Corporation immediately prior to such transaction or series of transactions.

VII. MISCELLANEOUS

     1. No Effect on Terms of Employment. Participation in the Plan shall not create a
right to further employment with the Participant’s employer (the “Employer”) and shall not
interfere with the ability of the Employer to terminate, with or without cause, or change the terms
of employment of a Participant at any time.

     2. Grants to Participants in Foreign Countries. In making grants to Participants in
foreign countries, the Administrator has the full discretion to deviate from this Statement of
Terms and Conditions in order to adjust grants under the Plan to prevailing local conditions,
including custom and legal and tax requirements. Furthermore, the Corporation reserves the right
to impose other requirements on the Participant’s participation in the Plan on the Award and on
any shares acquired under the Plan, to the extent the Corporation determines it is necessary or
advisable in order to comply with local law or facilitate the administration of the Plan, and to
require the Participant to sign any additional agreements or undertaking that may be necessary to
accomplish the foregoing.

13.

 

Officers

     3. Information Notification. Any information required to be given under the terms of
an Award shall be addressed to the Corporation in care of its Corporate Secretary at McKesson
Plaza, One Post Street, San Francisco, California 94104, and any notice to be given to a
Participant shall be addressed to him at the address indicated beneath his or her name on the
Agreement or such other address as either party may designate in writing to the other. Any such
notice shall be deemed to have been duly given when enclosed in a properly sealed envelope or
wrapper addressed as aforesaid, registered or certified and deposited (postage or registration or
certification fee prepaid) in a post office or branch post office.

     4. Administrator Decisions Conclusive. All decisions of the Administrator
administering the Plan upon any questions arising under the Plan, under this Statement of Terms and
Conditions, or under an Agreement, shall be conclusive.

     5. No Effect on Other Benefit Plans. Nothing herein contained shall affect a
Participant’s right to participate in and receive benefits from and in accordance with the then
current provisions of any pensions, insurance or other employment welfare plan or program offered
by the Corporation.

     6. Withholding. Regardless of any action the Corporation or the Employer takes with
respect to any federal, state or local income tax, social insurance, payroll tax, payment on
account or other tax-related items related to the Participant’s participation in the Plan and
legally applicable to the Participant (“Tax-Related Items”), the Participant acknowledges that the
ultimate liability for all Tax-Related Items is and remains his or her responsibility and may
exceed the amount actually withheld by the Corporation or the Employer. The Participant further
acknowledges that the Corporation and/or the Employer (1) make no representations or undertakings
regarding the treatment of any Tax-Related Items in connection with any aspect of the Award,
including the grant, vesting or exercise of the Award, as applicable, the subsequent sale of Shares
acquired pursuant to the Plan and the receipt of any dividends and/or dividend equivalents; and (2)
do not commit and are under no obligation to structure the terms of the grant or any aspect of the
Award to reduce or eliminate the Participant’s liability for Tax-Related Items or achieve any
particular tax result. Further, if the Participant has become subject to tax in more than one
jurisdiction between the Grant Date and the date of any relevant taxable event, the Participant
acknowledges that the Corporation and/or the Employer (or former employer, as applicable) may be
required to withhold or account for Tax-Related Items in more than one jurisdiction.

     Prior to any relevant taxable or tax withholding event, as applicable, the Participant will
pay or make adequate arrangements satisfactory to the Corporation and/or the Employer, or their
respective agents, at their discretion, to satisfy the obligations with regard to all Tax-Related
Items by one or a combination of the following: (1) withholding from the Participant’s wages or
other cash compensation paid to him or her by the Corporation and/or the Employer; (2) withholding
from proceeds of the sale of Shares acquired under the Plan either through a voluntary sale or
through a mandatory sale arranged by the Corporation (on the Participant’s behalf pursuant to this
authorization and any other authorization the Corporation and/or the broker designated by the
Corporation may require the Participant to sign in connection with the sale of Shares); or (3)
withholding Shares to be issued upon grant, vesting/settlement or exercise, as applicable.
Calculation of the number of Shares to be withheld shall be made based on the

14.

 

Officers

closing price of the Common Stock on the New York Stock Exchange on the date that the amount
of tax to be withheld is determined. In no event, however, shall the Corporation be required to
issue fractional shares of Stock. With respect to an Award other than an Option, if adequate
arrangements to satisfy the obligations with regard to all Tax-Related Items are not made by the
Participant with the Corporation and/or the Employer prior to the relevant taxable event, the
Corporation will satisfy such obligations as provided above in (3) of this paragraph.

     To avoid negative accounting treatment, the Corporation may withhold or account for
Tax-Related Items by considering applicable minimum statutory withholding amounts or other
applicable withholding rates. If the obligation for Tax-Related Items is satisfied by withholding
in Shares, for tax purposes, the Participant will be deemed to have been issued the full number of
Shares subject to the Award, notwithstanding that a number of the Shares are held back solely for
the purpose of paying the Tax-Related Items due as a result of any aspect of the Participant’s
participation in the Plan.

     Finally, the Participant shall pay to the Corporation or the Employer any amount of
Tax-Related Items that the Corporation or the Employer may be required to withhold or account for
as a result of the Participant’s participation in the Plan that cannot be satisfied by the means
previously described. The Corporation may refuse to issue or deliver the Shares or the proceeds of
the sale of Shares if the Participant fails to comply with his or her obligations in connection
with the Tax-Related Items.

     The Administrator shall be authorized to establish such rules, forms and procedures as it
deems necessary to implement the foregoing.

     7. Successors. This Statement of Terms and Conditions and the Award Agreements shall
be binding upon and inure to the benefit of any successor or successors of the Corporation.
“Participant” as used herein shall include the Participant’s Beneficiary.

     8. Delaware Law. The interpretation, performance, and enforcement of this Statement
of Terms and Conditions and all Award Agreements shall be governed by the laws of the State of
Delaware.

     9. Data Privacy. By accepting the Award, the Participant hereby explicitly and
unambiguously consents to the collection, use and transfer, in electronic or other form, of his or
her personal data as described in this document by and among, as applicable, the Employer and the
Corporation and its Affiliates for the exclusive purpose of implementing, administering and
managing participation in the Plan.

          The Participant understands that the Corporation and the Employer hold certain personal
information about the Participant, including, but not limited, his or her name, home address and
telephone number, date of birth, social insurance or other identification number, salary,
nationality, job title, any Shares or directorships held in the Corporation, details of all
Options, Restricted Stock, Restricted Stock Units, Performance Shares, Other Share-Based Awards, or
any other entitlement to Shares of stock awarded, canceled, exercised, vested, unvested or
outstanding in the Participant’s favor, for the purpose of implementing, administering and managing
the Plan (“Data”). The Participant understands that Data may be

management of the Plan, that these recipients may be located in the Participant’s country or
elsewhere, such as in the United States of America, and that the recipient’s country may have
different data privacy laws and protections than the Participant’s country. The Participant
understands that he or she may request a list with the names and addresses of any potential
recipients of the Data by contacting the local human resources representative. The Participant
authorizes the recipients to receive, possess, use, retain and transfer the Data, in electronic or
other form, for the purposes of implementing, administering and managing participation in the Plan,
including any requisite transfer of such Data as may be required to a broker or other third party
with whom the Participant may elect to deposit any Shares of stock acquired under the Plan. The
Participant understands that Data will be held only as long as is necessary to implement,
administer and manage his or her participation in the Plan. The Participant understands that he or
she may, at any time, view Data, request additional information about the storage and processing of
Data, require any necessary amendments to Data or refuse or withdraw the consents herein, without
cost, by contacting in writing the local human resources representative. The Participant
understands, however, that refusing or withdrawing consent may affect his or her ability to
participate in the Plan. For more information on the consequences of refusal to consent or
withdrawal of consent, the Participant understands that he or she may contact the local human
resources representative.

I. INTRODUCTION

     The following terms and conditions shall apply to an Award granted under the Plan. This
Statement of Terms and Conditions is intended to meet the requirements of Code Section 409A and any
rules promulgated thereunder and is subject to the terms and conditions of the Plan. In the event
of any inconsistency between this Statement of Terms and Conditions and the Plan, the Plan shall
govern. Capitalized terms not otherwise defined in this Statement of Terms and Conditions shall
have the meaning set forth in the Plan.

II. OPTIONS

     1. Option Notice and Agreement. An Option granted under the Plan shall be evidenced
by an Option Agreement setting forth the terms and conditions of the Option, including whether the
Option is an Incentive Stock Option or a Nonstatutory Stock Option and the number Shares subject to
the Option. Each Option Agreement shall incorporate by reference and be subject to this Statement
of Terms and Conditions and the terms and conditions of the Plan.

     2. Exercise Price. The per Share Exercise Price of an Option, as specified in the
Option Agreement, shall be equal to or greater than the per Share Fair Market Value of the Shares
underlying the Option on the Grant Date.

     3. Option Period. An Option shall be exercisable only during the applicable Option
Period, and during such Option Period the exercisability of the Option shall be subject to the
vesting provisions of Section II.4 as modified by the rules set forth in Sections II.5 and V. The
Option Period shall be not more than seven years from the Grant Date.

     4. Vesting of Right to Exercise Options.

          (A) Except as provided in Section V, an Option shall be exercisable during the Option Period
in accordance with the following vesting schedule: (i) 25% of the Shares subject to the Option
shall vest on the first anniversary of the Grant Date; (ii) an additional 25% of the Shares shall
vest on the second anniversary of the Grant Date; (iii) an additional 25% of the Shares shall vest

Option shall vest on the fourth anniversary of the Grant Date.

1.

 

ECOT

Notwithstanding the foregoing, the Administrator may specify a different vesting schedule at
the time the Option is granted, which will be specified in the Option Agreement.

          (B) Any vested portion of an Option not exercised hereunder shall accumulate and be
exercisable at any time on or before the Termination Date, subject to the rules set forth in
Section V. No Option may be exercised for less than 5% of the total number of Shares then
available for exercise under such Option. In no event shall the Corporation be required to issue
fractional Shares.

     5. Limits on Option Period and Acceleration of Vesting. The Option Period may end
before the Termination Date, and in the circumstances described in Sections II.5(B), (D), (E) and
(F), the vesting schedule of an Option may be accelerated, (subject to the provisions of
Section V), as follows:

          (A) If a Participant ceases to be a bona fide employee of the Corporation or of its Affiliates
during the Option Period for reasons other than for Cause (as defined herein), Long-Term
Disability, Normal or Early Retirement or death, the Option Period shall end ninety days after the
date of the Participant’s termination of employment or on the Termination Date, whichever occurs
first and in all cases the Option shall be exercisable only to the extent that it was exercisable
under the provisions of the foregoing Section II.4 at the time of such termination of employment.
If a Participant is absent from work with the Corporation or an Affiliate because of his or her
Short- Term Disability or because the Participant is on an approved leave of absence, the
Participant shall not be deemed during the period of any such absence, by virtue of such absence
alone, to have terminated employment with the Corporation or an Affiliate except as the
Administrator may otherwise expressly determine. Notwithstanding the foregoing, if the Participant
is on a voluntarily leave of absence for the purpose of serving the government of the country of
which the Participant is a citizen or in which the Participant’s principal place of employment is
located and such leave exceeds twelve months in duration, then the Participant shall be deemed to
have terminated employment with the Corporation or an Affiliate for purposes of this
Section II.5(A).

          (B) If a Participant ceases to be a bona fide employee of the Corporation or of its Affiliates
(for reasons other than for Cause, Long-Term Disability, Normal or Early Retirement or
death) during the Option Period, the Administrator may, in its sole and absolute discretion (and
subject to conditions deemed appropriate in the circumstances) approve the continuation of the
vesting schedule of the Participant’s Option. The Option Period for any Option that continues to
vest pursuant to this subsection (B) shall end ninety days after the last Option installment vests,
or on the Termination Date, whichever occurs first.

          (C) If the Participant’s employment is terminated for Cause during the Option Period, the
Option Period shall end on the date of such termination of employment and the Option shall
thereupon not be exercisable to any extent whatsoever.

          (D) If a Participant ceases to be a bona fide employee of the Corporation or of its Affiliates
due to his or her Long-Term Disability during the Option Period, the vesting schedule of the
Participant’s Option shall be accelerated, the Option shall become fully

2.

 

ECOT

exercisable and the Option Period shall end three years after the date of the Participant’s
termination of employment or on the Termination Date, whichever occurs first.

          (E) If the Participant’s employment is terminated:

               (i) by reason of Normal Retirement, the vesting schedule of the Participant’s Option shall be
accelerated and the Option shall become fully exercisable as of the date of Normal Retirement; or

               (ii) by reason of Early Retirement, the Option shall be exercisable only to the extent that it
was exercisable under the provisions of the foregoing Section II.4 at the time of such Early
Retirement; provided, however, that the Administrator may, in its sole discretion (and subject to
conditions deemed appropriate in the circumstances), either (A) accelerate the vesting schedule of
the Participant’s Option effective as of the date of the Participant’s Early Retirement or
(B) approve the continuation of the vesting schedule of the Participant’s Option.

               (iii) With respect to an Option held by a Participant at Normal or Early Retirement, the
Option Period for that portion of the Option designated as a Nonstatutory Stock Option shall end
three years after the date of retirement or on the Termination Date, whichever occurs first;
provided, however, that in the case of an Option held by a Participant at Early Retirement as to
which the Administrator exercises its discretionary authority to approve the continuation of the
vesting schedule, the Option Period shall end on the earlier of the Termination Date or three years
after the last Option installment vests.

          (F) If a Participant should die while in the employ of the Corporation or an Affiliate and
during the Option Period, the vesting schedule of the Participant’s Option shall be accelerated and
the Option shall become fully exercisable, the Option Period shall end three years after the date
of death or on the Termination Date, whichever occurs first, and the Participant’s Beneficiary may
exercise the entire unexercised portion of the then exercisable Shares covered by such Option (or
any lesser amount) remaining on the date of death.

          (G) If a Participant who ceases to be a bona fide employee of the Corporation or an Affiliate
is subsequently rehired prior to the expiration of his or her Option, then the Option shall
continue to remain outstanding until such time as the Participant subsequently terminates
employment. Upon the Participant’s subsequent termination of employment, the post-termination
exercise period calculated pursuant to the terms and conditions of this Section II.5 shall be
reduced by the number of days between the date of the Participant’s initial termination of
employment and his or her re-hire date; provided, however, that if the rehired Participant
continues to be employed by the Corporation or an Affiliate for at least one year from his or her
rehire date, then the post termination exercise period for the Option shall be determined in
accordance with Sections II.5(A) through (F) and shall not be adjusted as described above.

     6. Method of Exercise. A Participant may exercise an Option with respect to all or
any part of the exercisable Shares as follows:

          (A) By giving the Corporation, or its authorized representative designated for this purpose,
written notice of such exercise specifying the number of Shares as to which the

3.

 

ECOT

Option is so exercised. Such notice shall be accompanied by an amount equal to the Exercise
Price of such Shares, in the form of any one or combination of the following: cash or a certified
check, bank draft, postal or express money order payable to the order of the Corporation in lawful
money of the United States. Unless otherwise determined by the Administrator in his or her sole
discretion, the Participant may pay the Exercise Price, in whole or in part, by tendering to the
Corporation or its authorized representative Shares which have been owned by the Participant for at
least six months prior to said tender, and having a fair market value, as determined by the
Corporation, equal to the Exercise Price, or in lieu of the delivery of actual Shares in such
tender, the Corporation may accept an attestation by the Participant, in a form prescribed by the
Corporation or its authorized representative, that the Participant owns sufficient Shares of record
or in an account in street name to satisfy the Exercise Price, and such attestation will be deemed
a tender of Shares for purposes of this method of exercise. In the event a Participant tenders
Shares to pay the Exercise Price, tender of Shares acquired through exercise of an Incentive Stock
Option may result in unfavorable income tax consequences unless such Shares are held for at least
two years from the Grant Date of the Incentive Stock Option and one year from the date of exercise
of the Incentive Stock Option. The Corporation or its authorized representative may accept payment
of the Exercise Price in the form of a Participant’s personal check. Payment may also be made by
delivery (including by FAX transmission) to the Corporation or its authorized representative of an
executed irrevocable Option exercise form together with irrevocable instructions to an approved
registered investment broker to sell Shares in an amount sufficient to pay the Exercise Price plus
any applicable withholding taxes and to transfer the proceeds of such sale to the Corporation.

          (B) If required by the Corporation, by giving satisfactory assurance in writing, signed by the
Participant, the Participant shall give his or her assurance that the Shares subject to the Option
are being purchased for investment and not with a view to the distribution thereof; provided that
such assurance shall be deemed inapplicable to (1) any sale of the Shares by such Participant made
in accordance with the terms of a registration statement covering such sale, which has heretofore
been (or may hereafter be) filed and become effective under the U.S. Securities Act of 1933, as
amended (the “Securities Act”) and with respect to which no stop order suspending the effectiveness
thereof has been issued, and (2) any other sale of the Shares with respect to which, in the opinion
of counsel for the Corporation, such assurance is not required to be given in order to comply with
the provisions of the Securities Act.

          (C) As soon as practicable after receipt of the notice and the assurance described in
Sections II.6(A) and (B), the Corporation shall, without transfer or issue tax (except for
withholding tax arrangements contemplated in Section VII.6) and without other incidental expense to
the Participant, cause an appropriate book entry to be entered in the records of the Corporation’s
transfer agent recording the Participant’s unrestricted interest in the purchased Shares; provided,
however, that the time of such delivery may be postponed by the Corporation for such period as may
be required for it with reasonable diligence to comply with applicable registration requirements
under the Securities Act, the Exchange Act, any applicable listing requirements of any national
securities exchange and requirements under any other law or regulation applicable to the issuance
or transfer of the Shares.

     7. Limitations on Transfer. An Option shall, during a Participant’s lifetime, be
exercisable only by the Participant. No Option or any right granted thereunder shall be

4.

 

ECOT

transferable by the Participant by operation of law or otherwise, other than by will or the
laws of descent and distribution. Notwithstanding the foregoing, (i) a Participant may designate a
beneficiary to succeed, after the Participant’s death, to all of the Participant’s Options
outstanding on the date of death; (ii) a Nonstatutory Stock Option may be transferable pursuant to
a qualified domestic relations order as defined in the Code or Title I of the U.S. Employee
Retirement Income Security Act; and (iii) any Participant, who is a senior executive officer
recommended by the Chief Executive Officer of the Corporation and approved by the Administrator may
voluntarily transfer any Nonstatutory Stock Option to a Family Member as a gift or through a
transfer to an entity in which more than 50% of the voting interests are owned by Family Members
(or the Participant) in exchange for an interest in that entity. In the event of any attempt by a
Participant to alienate, assign, pledge, hypothecate, or otherwise dispose of an Option or of any
right thereunder, except as provided herein, or in the event of the levy of any attachment,
execution, or similar process upon the rights or interest hereby conferred, the Corporation at its
election may terminate the affected Option by notice to the Participant and the Option shall
thereupon become null and void.

     8. No Shareholder Rights. Neither a Participant nor any person entitled to exercise a
Participant’s rights in the event of the Participant’s death shall have any of the rights of a
shareholder with respect to the Shares subject to an Option except to the extent that a book entry
has been entered in the records of the Corporation’s transfer agent with respect to such Shares
upon the exercise of an Option.

III. RESTRICTED STOCK

     1. Restricted Stock Agreement. A Restricted Stock Award granted under the Plan shall
be evidenced by a Restricted Stock Agreement to be executed by the Participant and the Corporation
setting forth the terms and conditions of the Restricted Stock Award. Each Restricted Stock
Agreement shall incorporate by reference and be subject to this Statement of Terms and Conditions
and the terms and conditions of the Plan.

     2. Rights with Respect to Shares of Restricted Stock. Upon written acceptance of a

conditions described in the Plan, the Restricted Stock Agreement and herein, the Corporation shall
cause an appropriate book entry to be entered in the records of the Corporation’s transfer agent
recording the Participant’s interest in the Restricted Stock. From and after the Grant Date, the

described in the Plan, the Restricted Stock Agreement and this Statement of Terms and Conditions.

     3. Special Restrictions. Each Restricted Stock Award made under the Plan shall

discretion (and subject to conditions deemed appropriate in the circumstances), accelerate the
vesting schedule of the Participant’s Restricted Stock Award effective as of the date of the
Participant’s Early Retirement.

          (D) Restriction on Sale. The Compensation Committee reserves the right to impose a

which will be subject to all of the terms and conditions of the underlying Restricted Stock Unit
Award or Performance Shares, including the same vesting restrictions as the underlying award.

     4. Assignability. A Participant shall not be permitted to sell, transfer, pledge,
assign or encumber Restricted Stock Units or Performance Shares, other than pursuant to a qualified

     5. No Shareholder Rights. Neither a Participant nor any person entitled to exercise a
Participant’s rights in the event of the Participant’s death shall have any of the rights of a
shareholder with respect to the Share Equivalents subject to a Restricted Stock Unit Award or
Performance Shares except to the extent that a book entry has been entered in the records of the
Corporation’s transfer agent with respect to such Shares upon the settlement of any vested
Restricted Stock Unit Award of Performance Shares.

     6. Time of Payment of Restricted Stock Units and Performance Shares. Upon the lapse
of the restriction imposed on Restricted Stock Unit Awards or Performance Shares, all Restricted
Stock Units and Performance Shares that were not forfeited pursuant to Section IV.2(A) or V shall
be paid to the Participant as soon as reasonably practicable after the restrictions lapse. Payment
shall be made in Shares in the form of a an appropriate book entry entered in the records of the
Corporation’s transfer agent recording the Participant’s unrestricted interest in the number of
Shares equal to the number of vested Share Equivalents subject to the Restricted Stock Unit Award
or Performance Shares. The foregoing notwithstanding, the Participant may elect to defer payment
of the Restricted Stock Units in the manner described in Section IV.7.

     7. Deferral Election. Each Participant, pursuant to rules established by the
Administrator, may be eligible to elect to defer all or a percentage of any payment in respect of a
Restricted Stock Unit Award that he or she may be entitled to receive as determined pursuant to
Section IV.6. This election shall be made by giving notice in a manner and within the time
prescribed by the Administrator and in compliance with Code Section 409A. If a deferral is
permitted, the Participant must indicate the percentage (expressed in whole percentages) he or she
chooses to defer of any payment he or she may be entitled to receive. If no notice is given, the
Participant shall be deemed to have made no deferral election. Each deferral election filed with
the Corporation shall become irrevocable in accordance with the terms and conditions of the
Corporation’s Deferred Compensation Administration Plan III (DCAP III) (or any successor plan) and
in compliance with Code Section 409A.

V. SPECIAL FORFEITURE AND REPAYMENT RULES

     Any other provision of this Statement of Terms and Conditions to the contrary notwithstanding,
if the Administrator determines that a Participant has engaged in any of the actions described in 3
below, the consequences set forth in 1 and 2 below shall result:

     1. Any outstanding Option shall immediately and automatically terminate, be forfeited and
shall cease to be exercisable, without limitation. In addition, any Shares of Restricted Stock,
Restricted Stock Units or Performance Shares as to which the restrictions have not lapsed shall
immediately and automatically be forfeited and such Shares or Share Equivalents shall be returned
to the Corporation and all of the rights of the Participant to such Shares or Share Equivalents
shall immediately terminate.

     2. If the Participant exercised an Option within twelve months prior to the date upon which
the Corporation discovered that the Participant engaged in any actions described in 3 below, the
Participant, upon written notice from the Corporation, shall immediately pay to the Corporation the
economic value realized or obtained by the exercise of such Option measured at

9.

 

ECOT

the date of exercise. In addition, if the restrictions imposed on any grant of Restricted
Stock, Restricted Stock Units or Performance Shares lapsed within twelve months prior to the date
the Corporation discovered that the Participant engaged in any action described in 3 below, the
Participant, upon written notice from the Corporation, shall immediately pay to the Corporation the
economic value realized or obtained with respect to such Shares of Restricted Stock, the Restricted
Stock Units or the Performance Shares, measured at the date such Shares or Share Equivalents
vested.

     3. The consequences described in 1 and 2 above shall apply if the Participant, either before
or after termination of employment with the Corporation or its Affiliates:

          (A) Discloses to others, or takes or uses for his own purpose or the purpose of others, any
trade secrets, confidential information, knowledge, data or know-how or any other proprietary
information or intellectual property belonging to the Corporation or its Affiliates and obtained by
the Participant during the term of his employment, whether or not they are the Participant’s work
product. Examples of such confidential information or trade secrets include, without limitation,
customer lists, supplier lists, pricing and cost data, computer programs, delivery routes,
advertising plans, wage and salary data, financial information, research and development plans,
processes, equipment, product information and all other types and categories of information as to
which the Participant knows or has reason to know that the Corporation or its Affiliates intends or
expects secrecy to be maintained;

          (B) Fails to promptly return all documents and other tangible items belonging to the
Corporation or its Affiliates in the Participant’s possession or control, including all complete or
partial copies, recordings, abstracts, notes or reproductions of any kind made from or about such
documents or information contained therein, upon termination of employment, whether pursuant to
retirement or otherwise;

          (C) Fails to provide the Corporation with at least thirty (30) days’ written notice prior to
directly or indirectly engaging in, becoming employed by, or rendering services, advice or
assistance to any business in competition with the Corporation or its Affiliates. As used herein,
“business in competition” means any person, organization or enterprise which is engaged in or is
about to become engaged in any line of business engaged in by the Corporation or its Affiliates at
the time of the termination of the Participant’s employment with the Corporation or its Affiliates;

          (D) Fails to inform any new employer, before accepting employment, of the terms of this
paragraph and of the Participant’s continuing obligation to maintain the confidentiality of the
trade secrets and other confidential information belonging to the Corporation or its Affiliates and
obtained by the Participant during the term of his employment with the Corporation or any of its
Affiliates;

          (E) Induces or attempts to induce, directly or indirectly, any of the customers of the
Corporation or its Affiliates, employees, representatives or consultants to terminate, discontinue
or cease working with or for the Corporation or its Affiliates, or to breach any contract with the
Corporation or any of its Affiliates, in order to work with or for, or enter into a contract with,
the Participant or any third party; or

          (F) Engages in conduct which is not in good faith and which disrupts, damages, impairs or
interferes with the business, reputation or employees of the Corporation or its Affiliates;

          (G) Directly or indirectly engages in, becomes employed by, or renders services, advice or
assistance to any business in competition with the Corporation or its Affiliates, at any time
during the twelve months following termination of employment with the Corporation.

     The Administrator shall determine in its sole discretion whether the Participant has engaged
in any of the acts set forth in (A) through (G) above, and its determination shall be conclusive
and binding on all interested persons.

     Any provision of this Section V which is determined by a court of competent jurisdiction to be
invalid or unenforceable should be construed or limited in a manner that is valid and enforceable
and that comes closest to the business objectives intended by such invalid or unenforceable
provision, without invalidating or rendering unenforceable the remaining provisions of this
Section V.

VI. CHANGE IN CONTROL

     1. If as a result of a Change in Control, the Common Stock ceases to be listed for trading on
a national securities exchange (an “Exchange”), any Option, Restricted Stock Award, Restricted
Stock Unit Award, or Performance Shares that are unvested on the effective date of the Change in
Control shall continue to vest according to the terms and conditions of such Award, provided that
such Award is replaced with an award for voting securities of the resulting corporation or the
acquiring corporation, as the case may be, (including without limitation, the voting securities of
any corporation which as a result of the Change in Control owns the Corporation or all or
substantially all of the Corporation’s assets either directly or through one or more
subsidiaries) (the “Surviving Company”) which are traded on an Exchange (a “Replacement Award”),
which Replacement Award, (i) in the case of Options, shall consist of options with the number of
underlying shares and exercise price determined in a manner consistent with Code
Section 424(a) with vesting and any other terms continuing in the same manner as the replaced
Options; (ii) in the case of Performance Shares, shall consist of restricted stock or restricted
stock units with a value (determined using the Surviving Company’s stock price as of the effective
date of the Change in Control) equal to the value of the Performance Shares (determined using the
Corporation’s stock price and assuming attainment of target performance or actual performance
achieved, if greater, as of the effective date of the Change in Control), with any restrictions on
such restricted stock or restricted stock units lapsing at the end of the measuring period over
which performance for the replaced Performance Shares was to be measured prior to the granting of
the Replacement Award; and (iii) in the case of Restricted Stock or Restricted Stock Unit Awards,
shall consist of restricted stock or restricted stock units with a value (determined using the
Surviving Company’s stock price as of the effective date of the Change in Control) equal to the
value of the Restricted Stock or Restricted Stock Unit Awards (determined using the Corporation’s
stock price as of the effective date of the Change in Control), with any restrictions on such
restricted stock or restricted stock units lapsing at the same time and manner as the replaced
Award; provided, however, that in the event of a

11.

 

ECOT

termination by the Corporation without Cause or by the Participant for Good Reason during the
vesting period of any Replacement Award, the Replacement Award shall immediately vest; and provided
further that upon the vesting date of each Replacement Award, in addition to the fully vested
Replacement Award, the Participant shall be entitled to receive a lump sum cash payment equal to
the decrease, if any, in the value of a share of the Surviving Company’s stock from the effective
date of the Change in Control (as increased on a calendar quarterly basis using an annual interest
rate, as of the last business day of the calendar quarter, for zero-coupon U.S. government
securities with a constant maturity closest in length to the time period between the effective date
of the Change in Control and the date of the vesting of the Replacement Award) to the time of
vesting, multiplied by the total number of shares or share equivalents subject to the options,
restricted stock, or restricted stock units in the Replacement Award. If Options, Restricted Stock
Awards, Restricted Stock Unit Awards, or Performance Shares that are unvested at the effective time
of the Change in Control are not replaced with Replacement Awards, such Awards shall immediately
vest and, in the case of Performance Shares, shall vest based upon deemed attainment of target
performance or actual performance achieved, if greater.

     If as a result of a Change in Control, the Common Stock continues to be listed for trading on
an Exchange, any unvested Option, Restricted Stock Award, or Restricted Stock Unit Award shall
continue to vest according to the terms and conditions of such Award and any Performance Shares
shall be replaced with Restricted Stock or Restricted Stock Units where the number of such
Restricted Stock or Restricted Stock Units shall be equal to the number of Performance Shares
assuming attainment of target performance or actual performance achieved, if greater, as of the
effective date of the Change in Control with any restrictions on such Restricted Stock or
Restricted Stock Units lapsing at the end of the measuring period over which performance for the
replaced Performance Shares was to be measured prior to the granting of the replacement Award;
provided however, that, in the event of a termination by the Corporation without Cause or by the
Participant for Good Reason during the vesting period of an Award, such Award shall immediately
vest; and provided further that upon the vesting date of each Award, in addition to the fully
vested Award, the Participant shall be entitled to receive a lump sum cash payment equal to the
decrease, if any, in the value of a Share of the Corporation’s stock from the effective date of the
Change in Control (as increased on a calendar quarterly basis using an annual interest rate, as of
the last business day of the calendar quarter, for zero-coupon U.S. government securities with a
constant maturity closest in length to the time period between the effective date of the Change in
Control and the date of the vesting of the award) to the time of vesting, multiplied by the total
number of Shares or Share Equivalents subject to the Options, Restricted Stock, or Restricted Stock
Units.

     2. For purposes of this Statement of Terms and Conditions, a “Change in Control” of the
Corporation shall be deemed to have occurred if any of the events set forth in any one of the
following paragraphs shall occur:

          (i) Any “person” (as such term is used in Sections 13(d) and 14(d) of the Exchange Act),
excluding the Corporation or any of its Affiliates, a trustee or any fiduciary holding securities
under an employee benefit plan of the Corporation or any of its Affiliates, an underwriter
temporarily holding securities pursuant to an offering of such securities or a Corporation owned,
directly or indirectly, by stockholders of the Corporation in substantially the same proportions as
their ownership of the Corporation, is or becomes the “beneficial owner” (as

12.

 

ECOT

defined in Rule 13d-3 under the Exchange Act), directly or indirectly, of securities of the
Corporation representing 30% or more of the combined voting power of the Corporation’s then
outstanding securities; or

          (ii) During any period of not more than two consecutive years, individuals who at the
beginning of such period constitute the Board and any new director (other than a director
designated by a Person who has entered into an agreement with the Corporation to effect a
transaction described in clause (i), (iii) or (iv) of this paragraph) whose election by the Board
or nomination for election by the Corporation’s stockholders was approved by a vote of at least
two-thirds (2/3) of the directors then still in office who either were directors at the beginning
of the period or whose election or nomination for election was previously so approved, cease for
any reason to constitute a majority thereof; or

          (iii) The shareholders of the Corporation approve a merger or consolidation of the Corporation
with any other Corporation, other than (A) a merger or consolidation which would result in the
voting securities of the Corporation outstanding immediately prior thereto continuing to represent
(either by remaining outstanding or by being converted into voting securities of the surviving
entity), in combination with the ownership of any trustee or other fiduciary holding securities
under an employee benefit plan of the Corporation, at least 50% of the combined voting power of the
voting securities of the Corporation or such surviving entity outstanding immediately after such
merger or consolidation, or (B) a merger or consolidation effected to implement a recapitalization
of the Corporation (or similar transaction) in which no person acquires more than 50% of the
combined voting power of the Corporation’s then outstanding securities; or

          (iv) The shareholders of the Corporation approve a plan of complete liquidation of the
Corporation or an agreement for the sale or disposition by the Corporation of all or substantially
all of the Corporation’s assets.

     Notwithstanding the foregoing, no Change in Control shall be deemed to have occurred if there
is consummated any transaction or series of integrated transactions immediately following which the
holders of the Stock immediately prior to such transaction or series of transactions continue to
have the same proportionate ownership in an entity which owns all or substantially all of the
assets of the Corporation immediately prior to such transaction or series of transactions.

VII. MISCELLANEOUS

     1. No Effect on Terms of Employment. Participation in the Plan shall not create a
right to further employment with the Participant’s employer (the “Employer”) and shall not
interfere with the ability of the Employer to terminate, with or without cause, or change the terms
of employment of a Participant at any time.

     2. Grants to Participants in Foreign Countries. In making grants to Participants in
foreign countries, the Administrator has the full discretion to deviate from this Statement of
Terms and Conditions in order to adjust grants under the Plan to prevailing local conditions,
including custom and legal and tax requirements. Furthermore, the Corporation reserves the right
to impose other requirements on the Participant’s participation in the Plan on the Award

13.

 

ECOT

and on any shares acquired under the Plan, to the extent the Corporation determines it is
necessary or advisable in order to comply with local law or facilitate the administration of the
Plan, and to require the Participant to sign any additional agreements or undertaking that may be
necessary to accomplish the foregoing.

     3. Information Notification. Any information required to be given under the terms of
an Award shall be addressed to the Corporation in care of its Corporate Secretary at McKesson
Plaza, One Post Street, San Francisco, California 94104, and any notice to be given to a
Participant shall be addressed to him at the address indicated beneath his or her name on the
Agreement or such other address as either party may designate in writing to the other. Any such
notice shall be deemed to have been duly given when enclosed in a properly sealed envelope or
wrapper addressed as aforesaid, registered or certified and deposited (postage or registration or
certification fee prepaid) in a post office or branch post office.

     4. Administrator Decisions Conclusive. All decisions of the Administrator
administering the Plan upon any questions arising under the Plan, under this Statement of Terms and
Conditions, or under an Agreement, shall be conclusive.

     5. No Effect on Other Benefit Plans. Nothing herein contained shall affect a
Participant’s right to participate in and receive benefits from and in accordance with the then
current provisions of any pensions, insurance or other employment welfare plan or program offered
by the Corporation.

     6. Withholding. Regardless of any action the Corporation or the Employer takes with
respect to any federal, state or local income tax, social insurance, payroll tax, payment on
account or other tax-related items related to the Participant’s participation in the Plan and
legally applicable to the Participant (“Tax-Related Items”), the Participant acknowledges that the
ultimate liability for all Tax-Related Items is and remains his or her responsibility and may
exceed the amount actually withheld by the Corporation or the Employer. The Participant further
acknowledges that the Corporation and/or the Employer (1) make no representations or undertakings
regarding the treatment of any Tax-Related Items in connection with any aspect of the Award,
including the grant, vesting or exercise of the Award, as applicable, the subsequent sale of Shares
acquired pursuant to the Plan and the receipt of any dividends and/or dividend equivalents; and (2)
do not commit and are under no obligation to structure the terms of the grant or any aspect of the
Award to reduce or eliminate the Participant’s liability for Tax-Related Items or achieve any
particular tax result. Further, if the Participant has become subject to tax in more than one
jurisdiction between the Grant Date and the date of any relevant taxable event, the Participant
acknowledges that the Corporation and/or the Employer (or former employer, as applicable) may be
required to withhold or account for Tax-Related Items in more than one jurisdiction.

     Prior to any relevant taxable or tax withholding event, as applicable, the Participant will
pay or make adequate arrangements satisfactory to the Corporation and/or the Employer, or their
respective agents, at their discretion, to satisfy the obligations with regard to all Tax-Related
Items by one or a combination of the following: (1) withholding from the Participant’s wages or
other cash compensation paid to him or her by the Corporation and/or the Employer; (2) withholding
from proceeds of the sale of Shares acquired under the Plan either through a

14.

 

ECOT

voluntary sale or through a mandatory sale arranged by the Corporation (on the Participant’s
behalf pursuant to this authorization and any other authorization the Corporation and/or the broker
designated by the Corporation may require the Participant to sign in connection with the sale of
Shares); or (3) withholding Shares to be issued upon grant, vesting/settlement or exercise, as
applicable. Calculation of the number of Shares to be withheld shall be made based on the closing
price of the Common Stock on the New York Stock Exchange on the date that the amount of tax to be
withheld is determined. In no event, however, shall the Corporation be required to issue
fractional shares of Stock. With respect to an Award other than an Option, if adequate
arrangements to satisfy the obligations with regard to all Tax-Related Items are not made by the
Participant with the Corporation and/or the Employer prior to the relevant taxable event, the
Corporation will satisfy such obligations as provided above in (3) of this paragraph.

     To avoid negative accounting treatment, the Corporation may withhold or account for
Tax-Related Items by considering applicable minimum statutory withholding amounts or other
applicable withholding rates. If the obligation for Tax-Related Items is satisfied by withholding
in Shares, for tax purposes, the Participant will be deemed to have been issued the full number of
Shares subject to the Award, notwithstanding that a number of the Shares are held back solely for
the purpose of paying the Tax-Related Items due as a result of any aspect of the Participant’s
participation in the Plan.

     Finally, the Participant shall pay to the Corporation or the Employer any amount of
Tax-Related Items that the Corporation or the Employer may be required to withhold or account for
as a result of the Participant’s participation in the Plan that cannot be satisfied by the means
previously described. The Corporation may refuse to issue or deliver the Shares or the proceeds of
the sale of Shares if the Participant fails to comply with his or her obligations in connection
with the Tax-Related Items.

     The Administrator shall be authorized to establish such rules, forms and procedures as it
deems necessary to implement the foregoing.

     7. Successors. This Statement of Terms and Conditions and the Award Agreements shall
be binding upon and inure to the benefit of any successor or successors of the Corporation.
“Participant” as used herein shall include the Participant’s Beneficiary.

     8. Delaware Law. The interpretation, performance, and enforcement of this Statement
of Terms and Conditions and all Award Agreements shall be governed by the laws of the State of
Delaware.

     9. Data Privacy. By accepting the Award, the Participant hereby explicitly and
unambiguously consents to the collection, use and transfer, in electronic or other form, of his or
her personal data as described in this document by and among, as applicable, the Employer and the
Corporation and its Affiliates for the exclusive purpose of implementing, administering and
managing participation in the Plan.

          The Participant understands that the Corporation and the Employer hold certain personal
information about the Participant, including, but not limited, his or her name, home address and
telephone number, date of birth, social insurance or other identification number,

15.

 

ECOT

salary, nationality, job title, any Shares or directorships held in the Corporation, details
of all Options, Restricted Stock, Restricted Stock Units, Performance Shares, Other Share-Based
Awards, or any other entitlement to Shares of stock awarded, canceled, exercised, vested, unvested
or outstanding in the Participant’s favor, for the purpose of implementing, administering and
managing the Plan (“Data”). The Participant understands that Data may be transferred to any third
parties assisting in the implementation, administration and management of the Plan, that these
recipients may be located in the Participant’s country or elsewhere, such as in the United States
of America, and that the recipient’s country may have different data privacy laws and protections
than the Participant’s country. The Participant understands that he or she may request a list with
the names and addresses of any potential recipients of the Data by contacting the local human
resources representative. The Participant authorizes the recipients to receive, possess, use,
retain and transfer the Data, in electronic or other form, for the purposes of implementing,
administering and managing participation in the Plan, including any requisite transfer of such Data
as may be required to a broker or other third party with whom the Participant may elect to deposit
any Shares of stock acquired under the Plan. The Participant understands that Data will be held
only as long as is necessary to implement, administer and manage his or her participation in the
Plan. The Participant understands that he or she may, at any time, view Data, request additional
information about the storage and processing of Data, require any necessary amendments to Data or
refuse or withdraw the consents herein, without cost, by contacting in writing the local human
resources representative. The Participant understands, however, that refusing or withdrawing
consent may affect his or her ability to participate in the Plan. For more information on the
consequences of refusal to consent or withdrawal of consent, the Participant understands that he or
she may contact the local human resources representative.

Participant shall not be deemed during the period of any such absence, by virtue of such absence
alone, to have terminated employment with the Corporation or an Affiliate except as the
Administrator may otherwise expressly determine. Notwithstanding the foregoing, if the Participant
is on a voluntarily leave of absence for the purpose of serving the government of the country of
which the Participant is a citizen or in which the Participant’s principal place of employment is
located and such leave exceeds twelve months in duration, then the Participant shall be deemed to
have terminated employment with the Corporation or an Affiliate for purposes of this
Section II.5(A).

          (B) If a Participant ceases to be a bona fide employee of the Corporation or of its Affiliates
(for reasons other than for Cause, Long-Term Disability, Normal or Early Retirement or
death) during the Option Period, the Administrator may, in its sole and absolute discretion (and
subject to conditions deemed appropriate in the circumstances) approve the continuation of the
vesting schedule of the Participant’s Option. The Option Period for any Option that continues to
vest pursuant to this subsection (B) shall end ninety days after the last Option installment vests,
or on the Termination Date, whichever occurs first.

          (C) If the Participant’s employment is terminated for Cause during the Option Period, the
Option Period shall end on the date of such termination of employment and the Option shall
thereupon not be exercisable to any extent whatsoever.

          (D) If a Participant ceases to be a bona fide employee of the Corporation or of its Affiliates
due to his or her Long-Term Disability during the Option Period, the vesting schedule of the
Participant’s Option shall be accelerated, the Option shall become fully exercisable and the Option
Period shall end three years after the date of the Participant’s termination of employment or on
the Termination Date, whichever occurs first.

          (E) If the Participant’s employment is terminated:

2.

 

Employees

               (i) by reason of Normal Retirement, the vesting schedule of the Participant’s Option shall be
accelerated and the Option shall become fully exercisable as of the date of Normal Retirement; or

               (ii) by reason of Early Retirement, the Option shall be exercisable only to the extent that it
was exercisable under the provisions of the foregoing Section II.4 at the time of such Early
Retirement; provided, however, that the Administrator may, in its sole discretion (and subject to
conditions deemed appropriate in the circumstances), either (A) accelerate the vesting schedule of
the Participant’s Option effective as of the date of the Participant’s Early Retirement or
(B) approve the continuation of the vesting schedule of the Participant’s Option.

               (iii) With respect to an Option held by a Participant at Normal or Early Retirement, the
Option Period for that portion of the Option designated as a Nonstatutory Stock Option shall end
three years after the date of retirement or on the Termination Date, whichever occurs first;
provided, however, that in the case of an Option held by a Participant at Early Retirement as to
which the Administrator exercises its discretionary authority to approve the continuation of the
vesting schedule, the Option Period shall end on the earlier of the Termination Date or three years
after the last Option installment vests.

          (F) If a Participant should die while in the employ of the Corporation or an Affiliate and
during the Option Period, the vesting schedule of the Participant’s Option shall be accelerated and
the Option shall become fully exercisable, the Option Period shall end three years after the date
of death or on the Termination Date, whichever occurs first, and the Participant’s Beneficiary may
exercise the entire unexercised portion of the then exercisable Shares covered by such Option (or
any lesser amount) remaining on the date of death.

          (G) If a Participant who ceases to be a bona fide employee of the Corporation or an Affiliate
is subsequently rehired prior to the expiration of his or her Option, then the Option shall
continue to remain outstanding until such time as the Participant subsequently terminates
employment. Upon the Participant’s subsequent termination of employment, the post-termination
exercise period calculated pursuant to the terms and conditions of this Section II.5 shall be
reduced by the number of days between the date of the Participant’s initial termination of
employment and his or her re-hire date; provided, however, that if the rehired Participant
continues to be employed by the Corporation or an Affiliate for at least one year from his or her
rehire date, then the post termination exercise period for the Option shall be determined in
accordance with Sections II.5(A) through (F) and shall not be adjusted as described above.

     6. Method of Exercise. A Participant may exercise an Option with respect to all or
any part of the exercisable Shares as follows:

          (A) By giving the Corporation, or its authorized representative designated for this purpose,
written notice of such exercise specifying the number of Shares as to which the Option is so
exercised. Such notice shall be accompanied by an amount equal to the Exercise Price of such
Shares, in the form of any one or combination of the following: cash or a certified check, bank
draft, postal or express money order payable to the order of the Corporation in lawful money of the
United States. Unless otherwise determined by the Administrator in his or

3.

 

Employees

her sole discretion, the Participant may pay the Exercise Price, in whole or in part, by
tendering to the Corporation or its authorized representative Shares which have been owned by the
Participant for at least six months prior to said tender, and having a fair market value, as
determined by the Corporation, equal to the Exercise Price, or in lieu of the delivery of actual
Shares in such tender, the Corporation may accept an attestation by the Participant, in a form
prescribed by the Corporation or its authorized representative, that the Participant owns
sufficient Shares of record or in an account in street name to satisfy the Exercise Price, and such
attestation will be deemed a tender of Shares for purposes of this method of exercise. In the
event a Participant tenders Shares to pay the Exercise Price, tender of Shares acquired through
exercise of an Incentive Stock Option may result in unfavorable income tax consequences unless such
Shares are held for at least two years from the Grant Date of the Incentive Stock Option and one
year from the date of exercise of the Incentive Stock Option. The Corporation or its authorized
representative may accept payment of the Exercise Price in the form of a Participant’s personal
check. Payment may also be made by delivery (including by FAX transmission) to the Corporation or
its authorized representative of an executed irrevocable Option exercise form together with
irrevocable instructions to an approved registered investment broker to sell Shares in an amount
sufficient to pay the Exercise Price plus any applicable withholding taxes and to transfer the
proceeds of such sale to the Corporation.

          (B) If required by the Corporation, by giving satisfactory assurance in writing, signed by the
Participant, the Participant shall give his or her assurance that the Shares subject to the Option
are being purchased for investment and not with a view to the distribution thereof; provided that
such assurance shall be deemed inapplicable to (1) any sale of the Shares by such Participant made
in accordance with the terms of a registration statement covering such sale, which has heretofore
been (or may hereafter be) filed and become effective under the U.S. Securities Act of 1933, as
amended (the “Securities Act”) and with respect to which no stop order suspending the effectiveness
thereof has been issued, and (2) any other sale of the Shares with respect to which, in the opinion
of counsel for the Corporation, such assurance is not required to be given in order to comply with
the provisions of the Securities Act.

          (C) As soon as practicable after receipt of the notice and the assurance described in
Sections II.6(A) and (B), the Corporation shall, without transfer or issue tax (except for
withholding tax arrangements contemplated in Section VII.6) and without other incidental expense to
the Participant, cause an appropriate book entry to be entered in the records of the Corporation’s
transfer agent recording the Participant’s unrestricted interest in the purchased Shares; provided,
however, that the time of such delivery may be postponed by the Corporation for such period as may
be required for it with reasonable diligence to comply with applicable registration requirements
under the Securities Act, the Exchange Act, any applicable listing requirements of any national
securities exchange and requirements under any other law or regulation applicable to the issuance
or transfer of the Shares.

     7. Limitations on Transfer. An Option shall, during a Participant’s lifetime, be
exercisable only by the Participant. No Option or any right granted thereunder shall be
transferable by the Participant by operation of law or otherwise, other than by will or the laws of
descent and distribution. Notwithstanding the foregoing, (i) a Participant may designate a
beneficiary to succeed, after the Participant’s death, to all of the Participant’s Options
outstanding on the date of death; (ii) a Nonstatutory Stock Option may be transferable pursuant

4.

 

Employees

to a qualified domestic relations order as defined in the Code or Title I of the U.S. Employee
Retirement Income Security Act; and (iii) any Participant, who is a senior executive officer
recommended by the Chief Executive Officer of the Corporation and approved by the Administrator may
voluntarily transfer any Nonstatutory Stock Option to a Family Member as a gift or through a
transfer to an entity in which more than 50% of the voting interests are owned by Family Members
(or the Participant) in exchange for an interest in that entity. In the event of any attempt by a
Participant to alienate, assign, pledge, hypothecate, or otherwise dispose of an Option or of any
right thereunder, except as provided herein, or in the event of the levy of any attachment,
execution, or similar process upon the rights or interest hereby conferred, the Corporation at its
election may terminate the affected Option by notice to the Participant and the Option shall
thereupon become null and void.

     8. No Shareholder Rights. Neither a Participant nor any person entitled to exercise a
Participant’s rights in the event of the Participant’s death shall have any of the rights of a
shareholder with respect to the Shares subject to an Option except to the extent that a book entry
has been entered in the records of the Corporation’s transfer agent with respect to such Shares
upon the exercise of an Option.

XI. RESTRICTED STOCK

     1. Restricted Stock Agreement. A Restricted Stock Award granted under the Plan shall
be evidenced by a Restricted Stock Agreement to be executed by the Participant and the Corporation
setting forth the terms and conditions of the Restricted Stock Award. Each Restricted Stock
Agreement shall incorporate by reference and be subject to this Statement of Terms and Conditions
and the terms and conditions of the Plan.

     2. Rights with Respect to Shares of Restricted Stock. Upon written acceptance of a
grant of Restricted Stock Award by a Participant, including the restrictions and other terms and
conditions described in the Plan, the Restricted Stock Agreement and herein, the Corporation shall
cause an appropriate book entry to be entered in the records of the Corporation’s transfer agent
recording the Participant’s interest in the Restricted Stock. From and after the Grant Date, the
Participant shall have absolute ownership of such Shares of Restricted Stock, including the right
to vote and to receive dividends thereon, subject to the terms, conditions and restrictions
described in the Plan, the Restricted Stock Agreement and this Statement of Terms and Conditions.

     3. Special Restrictions. Each Restricted Stock Award made under the Plan shall
contain the following terms, conditions and restrictions and such additional terms, conditions and
restrictions as may be determined by the Administrator; provided, however, that no Restricted Stock
grant shall be subject to additional terms, conditions and restrictions which are more favorable to
a Participant than the terms, conditions and restrictions set forth elsewhere in the Plan, the
Restricted Stock Agreement or this Statement of Terms and Conditions.

          (A) Restrictions. Until the restrictions imposed on any Restricted Stock grant shall
lapse, Shares of Restricted Stock granted to a Participant: (i) shall not be sold, assigned,
transferred, pledged, hypothecated, or otherwise disposed of, other than pursuant to a qualified
domestic relations order as defined in the Code or Title I of the U.S. Employee Retirement

5.

 

Employees

Income Security Act and (ii) shall, if the Participant’s continuous employment with the
Corporation or any of its Affiliates shall terminate for any reason (except as otherwise provided
in the Plan or in Section III.3(B)) be returned to the Corporation forthwith, and all the rights of
the Participant to such Shares shall immediately terminate. If a Participant is absent from work
with the Corporation or an Affiliate because of his or her Short-Term Disability or because the
Participant is on an approved leave of absence, the Participant shall not be deemed during the
period of any such absence, by virtue of such absence alone, to have terminated employment with the
Corporation or an Affiliate except as the Administrator may otherwise expressly determine.
Notwithstanding the foregoing, if the Participant is on a voluntarily leave of absence for the
purpose of serving the government of the country of which the Participant is a citizen or in which
the Participant’s principal place of employment is located and such leave exceeds twelve months in
duration, then the Participant shall be deemed to have terminated employment with the Corporation
or an Affiliate for purposes of this Section III.3(A).

          (B) Termination of Employment by Reason of Death, Long-Term Disability or Normal
Retirement. Notwithstanding any provision contained herein or in the Plan or the Restricted
Stock Agreement to the contrary, if a Participant who has been in the continuous employment of the
Corporation or any of its Affiliates since the Grant Date of a Restricted Stock Award ceases to be
a bona fide employee of the Corporation or an Affiliate as a result of death, Long-Term Disability,
or Normal Retirement, then the restrictions imposed on any Restricted Stock Award shall lapse as to
all Shares granted to such Participant pursuant to such Restricted Stock Award on the date of such
termination.

          (C) Termination of Employment by Reason of Early Retirement. Notwithstanding any
provision contained herein or in the Plan or the Restricted Stock Agreement to the contrary, if a
Participant who has been in the continuous employment of the Corporation or any of its Affiliates
since the Grant Date of a Restricted Stock Award ceases to be a bona fide employee of the
Corporation or an Affiliate by reason of Early Retirement, the Administrator may, in its sole
discretion (and subject to conditions deemed appropriate in the circumstances), accelerate the
vesting schedule of the Participant’s Restricted Stock Award effective as of the date of the
Participant’s Early Retirement.

     4. Dividends. Cash dividends paid with respect to the Restricted Stock during the
Restriction Period shall be paid directly to the Participant during the Restriction Period. Stock
dividends paid with respect to Restricted Stock during the Restriction Period shall be treated as
Restricted Stock which shall be subject to the same restrictions as the original award for the
duration of the Restricted Period.

     5. Election to Recognize Gross Income in the Year of Grant. If any Participant
validly elects within thirty days of the Grant Date, to include in gross income for federal income
tax purposes an amount equal to the fair market value of the Shares of Restricted Stock granted on
the Grant Date, such Participant shall pay to the Corporation, or make arrangements satisfactory to
the Administrator to pay to the Corporation in the year of such grant, any federal, state or local
taxes required to be withheld with respect to such Shares in accordance with Section VII.6.

6.

 

Employees

     6. Restrictive Legend. Each book entry in the records of the Corporation’s transfer
agent evidencing Shares granted pursuant to a Restricted Stock grant may bear an appropriate legend
referring to the terms, conditions and restrictions described in the Plan, the Restricted Stock
Agreement and this Statement of Terms and Conditions.

     7. Expiration of Restricted Period. If and when the Restriction Period applicable to
the Restricted Stock expires without a prior forfeiture, an appropriate book entry recording the
Participant’s interest in the unrestricted Shares shall be entered on the records of the
Corporation’s transfer agent.

XII. RESTRICTED STOCK UNITS AND PERFORMANCE SHARES

     1. Award Agreement.

          (A) A Restricted Stock Unit Award granted under the Plan shall be evidenced by a Restricted
Stock Unit Agreement to be executed by the Participant and the Corporation setting forth the terms
and conditions of the Restricted Stock Unit Award. Each Restricted Stock Unit Agreement shall
incorporate by reference and be subject to this Statement of Terms and Conditions and the terms and
conditions of the Plan.

          (B) Performance Shares granted under the Plan shall be evidenced by a Performance Share
Agreement to be executed by the Participant and the Corporation setting forth the terms and
conditions of the Performance Shares. Each Performance Share Agreement shall incorporate by
reference and be subject to this Statement of Terms and Conditions and the terms and conditions of
the Plan.

     2. Special Restrictions. Restricted Stock Unit Awards and Performance Shares granted
under the Plan shall contain the following terms, conditions and restrictions and such additional
terms, conditions and restrictions as may be determined by the Administrator; provided, however,
that no such Award shall be subject to additional terms, conditions and restrictions which are more
favorable to a Participant than the terms, conditions and restrictions set forth elsewhere in the
Plan, the Restricted Stock Unit Agreement or Performance Share Agreement or this Statement of Terms
and Conditions.

          (A) Restrictions. If a Participant ceases to be a bona fide employee of the
Corporation or an Affiliates (except as otherwise provided in the Plan or in Section III.3(B) or
(C)) prior to the lapse of the restrictions imposed on the Award, the unvested Restricted Stock
Units or Performance Shares shall be returned to the Corporation, and all the rights of the
Participant to such Share Equivalents shall immediately terminate. If a Participant is absent from
work with the Corporation or an Affiliate because of his or her Short-Term Disability or because
the Participant is on an approved leave of absence, the Participant shall not be deemed during the
period of any such absence, by virtue of such absence alone, to have terminated employment with the
Corporation or an Affiliate except as the Administrator may otherwise expressly determine.
Notwithstanding the foregoing, if the Participant is on a voluntarily leave of absence for the
purpose of serving the government of the country of which the Participant is a citizen or in which
the Participant’s principal place of employment is located and such leave exceeds

7.

 

Employees

twelve months in duration, then the Participant shall be deemed to have terminated employment
with the Corporation or an Affiliate for purposes of this Section IV.2(A).

          (B) Termination of Employment by Reason of Death, Long-Term Disability or Normal
Retirement. Notwithstanding any provision contained herein or in the Plan, the Restricted
Stock Unit Agreement or Performance Share Agreement to the contrary, if a Participant who has been
in the continuous employment of the Corporation or any of its Affiliates since the Grant Date
shall, while in such employment, be terminated as a result of death, Long-Term Disability, or
Normal Retirement, then the restrictions imposed on any Restricted Stock Unit Award or Performance
Shares shall lapse as to all Share Equivalents granted to such Participant pursuant to such Award
on the date of such termination.

          (C) Termination of Employment by Reason of Early Retirement. Notwithstanding any
provision contained herein or in the Plan or the Restricted Stock Unit Agreement or Performance
Share Agreement to the contrary, if a Participant who has been in continuous employment of the
Corporation or any of its Affiliates since the Grant Date of a Restricted Stock Unit Award or
Performance Share Award ceases to be a bona fide employee of the Corporation or an Affiliate by
reason of Early Retirement, the Administrator may, in its sole discretion (and subject to
conditions deemed appropriate in the circumstances), accelerate the vesting schedule of the
Participant’s Restricted Stock Units or Performance Shares effective as of the date of the
Participant’s Early Retirement.

     3. Dividend Equivalents. Dividend equivalents shall be credited in respect of
Restricted Stock Units and Performance Shares. Cash dividends shall be credited on behalf of the
Participant to a deferred cash account (in a manner designed to comply with Code Section 409A).
Stock dividends shall be converted into additional Restricted Stock Units or Performance Shares,
which will be subject to all of the terms and conditions of the underlying Restricted Stock Unit
Award or Performance Shares, including the same vesting restrictions as the underlying award.

     4. Assignability. A Participant shall not be permitted to sell, transfer, pledge,
assign or encumber Restricted Stock Units or Performance Shares, other than pursuant to a qualified
domestic relations order as defined in the Code or Title I of the U.S. Employee Retirement Income
Security Act.

     5. No Shareholder Rights. Neither a Participant nor any person entitled to exercise a
Participant’s rights in the event of the Participant’s death shall have any of the rights of a
shareholder with respect to the Share Equivalents subject to a Restricted Stock Unit Award or
Performance Shares except to the extent that a book entry has been entered in the records of the
Corporation’s transfer agent with respect to such Shares upon the settlement of any vested
Restricted Stock Unit Award of Performance Shares.

     6. Time of Payment of Restricted Stock Units and Performance Shares. Upon the lapse
of the restriction imposed on Restricted Stock Unit Awards or Performance Shares, all Restricted
Stock Units and Performance Shares that were not forfeited pursuant to Section IV.2(A) or V shall
be paid to the Participant as soon as reasonably practicable after the restrictions lapse. Payment
shall be made in Shares in the form of a an appropriate book entry

8.

 

Employees

entered in the records of the Corporation’s transfer agent recording the Participant’s
unrestricted interest in the number of Shares equal to the number of vested Share Equivalents
subject to the Restricted Stock Unit Award or Performance Shares. The foregoing notwithstanding,
the Participant may elect to defer payment of the Restricted Stock Units in the manner described in
Section IV.7.

     7. Deferral Election. Each Participant, pursuant to rules established by the
Administrator, may be eligible to elect to defer all or a percentage of any payment in respect of a
Restricted Stock Unit Award that he or she may be entitled to receive as determined pursuant to
Section IV.6. This election shall be made by giving notice in a manner and within the time
prescribed by the Administrator and in compliance with Code Section 409A. If a deferral is
permitted, the Participant must indicate the percentage (expressed in whole percentages) he or she
chooses to defer of any payment he or she may be entitled to receive. If no notice is given, the
Participant shall be deemed to have made no deferral election. Each deferral election filed with
the Corporation shall become irrevocable in accordance with the terms and conditions of the
Corporation’s Deferred Compensation Administration Plan III (DCAP III) (or any successor plan) and
in compliance with Code Section 409A.

XIII. SPECIAL FORFEITURE AND REPAYMENT RULES

     Any other provision of this Statement of Terms and Conditions to the contrary notwithstanding,
if the Administrator determines that a Participant has engaged in any of the actions described in 3
below, the consequences set forth in 1 and 2 below shall result:

     1. Any outstanding Option shall immediately and automatically terminate, be forfeited and
shall cease to be exercisable, without limitation. In addition, any Shares of Restricted Stock,
Restricted Stock Units or Performance Shares as to which the restrictions have not lapsed shall
immediately and automatically be forfeited and such Shares or Share Equivalents shall be returned
to the Corporation and all of the rights of the Participant to such Shares or Share Equivalents
shall immediately terminate.

     2. If the Participant exercised an Option within twelve months prior to the date upon which
the Corporation discovered that the Participant engaged in any actions described in 3 below, the
Participant, upon written notice from the Corporation, shall immediately pay to the Corporation the
economic value realized or obtained by the exercise of such Option measured at the date of
exercise. In addition, if the restrictions imposed on any grant of Restricted Stock, Restricted
Stock Units or Performance Shares lapsed within twelve months prior to the date the Corporation
discovered that the Participant engaged in any action described in 3 below, the Participant, upon
written notice from the Corporation, shall immediately pay to the Corporation the economic value
realized or obtained with respect to such Shares of Restricted Stock, the Restricted Stock Units or
the Performance Shares, measured at the date such Shares or Share Equivalents vested.

     3. The consequences described in 1 and 2 above shall apply if the Participant, either before
or after termination of employment with the Corporation or its Affiliates:

9.

 

Employees

          (A) Discloses to others, or takes or uses for his own purpose or the purpose of others, any
trade secrets, confidential information, knowledge, data or know-how or any other proprietary
information or intellectual property belonging to the Corporation or its Affiliates and obtained by
the Participant during the term of his employment, whether or not they are the Participant’s work
product. Examples of such confidential information or trade secrets include, without limitation,
customer lists, supplier lists, pricing and cost data, computer programs, delivery routes,
advertising plans, wage and salary data, financial information, research and development plans,
processes, equipment, product information and all other types and categories of information as to
which the Participant knows or has reason to know that the Corporation or its Affiliates intends or
expects secrecy to be maintained;

          (B) Fails to promptly return all documents and other tangible items belonging to the
Corporation or its Affiliates in the Participant’s possession or control, including all complete or
partial copies, recordings, abstracts, notes or reproductions of any kind made from or about such
documents or information contained therein, upon termination of employment, whether pursuant to
retirement or otherwise;

          (C) Fails to provide the Corporation with at least thirty (30) days’ written notice prior to
directly or indirectly engaging in, becoming employed by, or rendering services, advice or
assistance to any business in competition with the Corporation or its Affiliates. As used herein,
“business in competition” means any person, organization or enterprise which is engaged in or is
about to become engaged in any line of business engaged in by the Corporation or its Affiliates at
the time of the termination of the Participant’s employment with the Corporation or its Affiliates;

          (D) Fails to inform any new employer, before accepting employment, of the terms of this
paragraph and of the Participant’s continuing obligation to maintain the confidentiality of the
trade secrets and other confidential information belonging to the Corporation or its Affiliates and
obtained by the Participant during the term of his employment with the Corporation or any of its
Affiliates;

          (E) Induces or attempts to induce, directly or indirectly, any of the customers of the

the Participant or any third party; or

          (F) Engages in conduct which is not in good faith and which disrupts, damages, impairs or

          (G) Directly or indirectly engages in, becomes employed by, or renders services, advice or
assistance to any business in competition with the Corporation or its Affiliates, at any time
during the twelve months following termination of employment with the Corporation.

10.

 

Employees

     The Administrator shall determine in its sole discretion whether the Participant has engaged
in any of the acts set forth in (A) through (G) above, and its determination shall be conclusive
and binding on all interested persons.

     Any provision of this Section V which is determined by a court of competent jurisdiction to be
invalid or unenforceable should be construed or limited in a manner that is valid and enforceable
and that comes closest to the business objectives intended by such invalid or unenforceable
provision, without invalidating or rendering unenforceable the remaining provisions of this
Section V.

XIV. CHANGE IN CONTROL

     1. If as a result of a Change in Control, the Common Stock ceases to be listed for trading on
a national securities exchange (an “Exchange”), any Option, Restricted Stock Award, Restricted
Stock Unit Award, or Performance Shares that are unvested on the effective date of the Change in
Control shall continue to vest according to the terms and conditions of such Award, provided that
such Award is replaced with an award for voting securities of the resulting corporation or the
acquiring corporation, as the case may be, (including without limitation, the voting securities of
any corporation which as a result of the Change in Control owns the Corporation or all or
substantially all of the Corporation’s assets either directly or through one or more
subsidiaries) (the “Surviving Company”) which are traded on an Exchange (a “Replacement Award”),
which Replacement Award, (i) in the case of Options, shall consist of options with the number of
underlying shares and exercise price determined in a manner consistent with Code
Section 424(a) with vesting and any other terms continuing in the same manner as the replaced
Options; (ii) in the case of Performance Shares, shall consist of restricted stock or restricted
stock units with a value (determined using the Surviving Company’s stock price as of the effective
date of the Change in Control) equal to the value of the Performance Shares (determined using the
Corporation’s stock price and assuming attainment of target performance or actual performance
achieved, if greater, as of the effective date of the Change in Control), with any restrictions on
such restricted stock or restricted stock units lapsing at the end of the measuring period over
which performance for the replaced Performance Shares was to be measured prior to the granting of
the Replacement Award; and (iii) in the case of Restricted Stock or Restricted Stock Unit Awards,
shall consist of restricted stock or restricted stock units with a value (determined using the
Surviving Company’s stock price as of the effective date of the Change in Control) equal to the
value of the Restricted Stock or Restricted Stock Unit Awards (determined using the Corporation’s
stock price as of the effective date of the Change in Control), with any restrictions on such
restricted stock or restricted stock units lapsing at the same time and manner as the replaced
Award; provided, however, that in the event of a termination by the Corporation without Cause or by
the Participant for Good Reason during the vesting period of any Replacement Award, the Replacement
Award shall immediately vest; and provided further that upon the vesting date of each Replacement
Award, in addition to the fully vested Replacement Award, the Participant shall be entitled to
receive a lump sum cash payment equal to the decrease, if any, in the value of a share of the
Surviving Company’s stock from the effective date of the Change in Control (as increased on a
calendar quarterly basis using an annual interest rate, as of the last business day of the calendar
quarter, for zero-coupon U.S. government securities with a constant maturity closest in length to
the time period between the effective date of the Change in Control and the date of the vesting of
the Replacement Award) to

11.

 

Employees

the time of vesting, multiplied by the total number of shares or share equivalents subject to
the options, restricted stock, or restricted stock units in the Replacement Award. If Options,
Restricted Stock Awards, Restricted Stock Unit Awards, or Performance Shares that are unvested at
the effective time of the Change in Control are not replaced with Replacement Awards, such Awards
shall immediately vest and, in the case of Performance Shares, shall vest based upon deemed
attainment of target performance or actual performance achieved, if greater.

     If as a result of a Change in Control, the Common Stock continues to be listed for trading on
an Exchange, any unvested Option, Restricted Stock Award, or Restricted Stock Unit Award shall
continue to vest according to the terms and conditions of such Award and any Performance Shares
shall be replaced with Restricted Stock or Restricted Stock Units where the number of such
Restricted Stock or Restricted Stock Units shall be equal to the number of Performance Shares
assuming attainment of target performance or actual performance achieved, if greater, as of the
effective date of the Change in Control with any restrictions on such Restricted Stock or
Restricted Stock Units lapsing at the end of the measuring period over which performance for the
replaced Performance Shares was to be measured prior to the granting of the replacement Award;
provided however, that, in the event of a termination by the Corporation without Cause or by the
Participant for Good Reason during the vesting period of an Award, such Award shall immediately
vest; and provided further that upon the vesting date of each Award, in addition to the fully
vested Award, the Participant shall be entitled to receive a lump sum cash payment equal to the
decrease, if any, in the value of a Share of the Corporation’s stock from the effective date of the
Change in Control (as increased on a calendar quarterly basis using an annual interest rate, as of
the last business day of the calendar quarter, for zero-coupon U.S. government securities with a
constant maturity closest in length to the time period between the effective date of the Change in
Control and the date of the vesting of the award) to the time of vesting, multiplied by the total
number of Shares or Share Equivalents subject to the Options, Restricted Stock, or Restricted Stock
Units.

     2. For purposes of this Statement of Terms and Conditions, a “Change in Control” of the
Corporation shall be deemed to have occurred if any of the events set forth in any one of the
following paragraphs shall occur:

               (i) Any “person” (as such term is used in Sections 13(d) and 14(d) of the Exchange Act),
excluding the Corporation or any of its Affiliates, a trustee or any fiduciary holding securities
under an employee benefit plan of the Corporation or any of its Affiliates, an underwriter
temporarily holding securities pursuant to an offering of such securities or a Corporation owned,
directly or indirectly, by stockholders of the Corporation in substantially the same proportions as
their ownership of the Corporation, is or becomes the “beneficial owner” (as defined in Rule 13d-3
under the Exchange Act), directly or indirectly, of securities of the Corporation representing 30%
or more of the combined voting power of the Corporation’s then outstanding securities; or

               (ii) During any period of not more than two consecutive years, individuals who at the
beginning of such period constitute the Board and any new director (other than a director

or nomination for election by the Corporation’s stockholders was approved by a vote of at least

12.

 

Employees

two-thirds (2/3) of the directors then still in office who either were directors at the
beginning of the period or whose election or nomination for election was previously so approved,
cease for any reason to constitute a majority thereof; or

               (iii) The shareholders of the Corporation approve a merger or consolidation of the Corporation
with any other Corporation, other than (A) a merger or consolidation which would result in the
voting securities of the Corporation outstanding immediately prior thereto continuing to represent
(either by remaining outstanding or by being converted into voting securities of the surviving
entity), in combination with the ownership of any trustee or other fiduciary holding securities
under an employee benefit plan of the Corporation, at least 50% of the combined voting power of the
voting securities of the Corporation or such surviving entity outstanding immediately after such
merger or consolidation, or (B) a merger or consolidation effected to implement a recapitalization
of the Corporation (or similar transaction) in which no person acquires more than 50% of the
combined voting power of the Corporation’s then outstanding securities; or

               (iv) The shareholders of the Corporation approve a plan of complete liquidation of the
Corporation or an agreement for the sale or disposition by the Corporation of all or substantially
all of the Corporation’s assets.

     Notwithstanding the foregoing, no Change in Control shall be deemed to have occurred if there
is consummated any transaction or series of integrated transactions immediately following which the
holders of the Stock immediately prior to such transaction or series of transactions continue to
have the same proportionate ownership in an entity which owns all or substantially all of the
assets of the Corporation immediately prior to such transaction or series of transactions.

XV. MISCELLANEOUS

     1. No Effect on Terms of Employment. Participation in the Plan shall not create a
right to further employment with the Participant’s employer (the “Employer”) and shall not
interfere with the ability of the Employer to terminate, with or without cause, or change the terms
of employment of a Participant at any time.

     2. Grants to Participants in Foreign Countries. In making grants to Participants in
foreign countries, the Administrator has the full discretion to deviate from this Statement of
Terms and Conditions in order to adjust grants under the Plan to prevailing local conditions,
including custom and legal and tax requirements. Furthermore, the Corporation reserves the right
to impose other requirements on the Participant’s participation in the Plan on the Award and on
any shares acquired under the Plan, to the extent the Corporation determines it is necessary or
advisable in order to comply with local law or facilitate the administration of the Plan, and to
require the Participant to sign any additional agreements or undertaking that may be necessary to
accomplish the foregoing.

     3. Information Notification. Any information required to be given under the terms of
an Award shall be addressed to the Corporation in care of its Corporate Secretary at McKesson
Plaza, One Post Street, San Francisco, California 94104, and any notice to be given to a
Participant shall be addressed to him at the address indicated beneath his or her name on the

13.

 

Employees

Agreement or such other address as either party may designate in writing to the other. Any
such notice shall be deemed to have been duly given when enclosed in a properly sealed envelope or
wrapper addressed as aforesaid, registered or certified and deposited (postage or registration or
certification fee prepaid) in a post office or branch post office.

     4. Administrator Decisions Conclusive. All decisions of the Administrator
administering the Plan upon any questions arising under the Plan, under this Statement of Terms and
Conditions, or under an Agreement, shall be conclusive.

     5. No Effect on Other Benefit Plans. Nothing herein contained shall affect a
Participant’s right to participate in and receive benefits from and in accordance with the then
current provisions of any pensions, insurance or other employment welfare plan or program offered
by the Corporation.

     6. Withholding. Regardless of any action the Corporation or the Employer takes with
respect to any federal, state or local income tax, social insurance, payroll tax, payment on
account or other tax-related items related to the Participant’s participation in the Plan and
legally applicable to the Participant (“Tax-Related Items”), the Participant acknowledges that the
ultimate liability for all Tax-Related Items is and remains his or her responsibility and may
exceed the amount actually withheld by the Corporation or the Employer. The Participant further
acknowledges that the Corporation and/or the Employer (1) make no representations or undertakings
regarding the treatment of any Tax-Related Items in connection with any aspect of the Award,
including the grant, vesting or exercise of the Award, as applicable, the subsequent sale of Shares
acquired pursuant to the Plan and the receipt of any dividends and/or dividend equivalents; and (2)
do not commit and are under no obligation to structure the terms of the grant or any aspect of the
Award to reduce or eliminate the Participant’s liability for Tax-Related Items or achieve any
particular tax result. Further, if the Participant has become subject to tax in more than one
jurisdiction between the Grant Date and the date of any relevant taxable event, the Participant
acknowledges that the Corporation and/or the Employer (or former employer, as applicable) may be
required to withhold or account for Tax-Related Items in more than one jurisdiction.

     Prior to any relevant taxable or tax withholding event, as applicable, the Participant will
pay or make adequate arrangements satisfactory to the Corporation and/or the Employer, or their
respective agents, at their discretion, to satisfy the obligations with regard to all Tax-Related
Items by one or a combination of the following: (1) withholding from the Participant’s wages or
other cash compensation paid to him or her by the Corporation and/or the Employer; (2) withholding
from proceeds of the sale of Shares acquired under the Plan either through a voluntary sale or
through a mandatory sale arranged by the Corporation (on the Participant’s behalf pursuant to this
authorization and any other authorization the Corporation and/or the broker designated by the
Corporation may require the Participant to sign in connection with the sale of Shares); or (3)
withholding Shares to be issued upon grant, vesting/settlement or exercise, as applicable.
Calculation of the number of Shares to be withheld shall be made based on the closing price of the
Common Stock on the New York Stock Exchange on the date that the amount of tax to be withheld is
determined. In no event, however, shall the Corporation be required to issue fractional shares of
Stock. With respect to an Award other than an Option, if adequate arrangements to satisfy the
obligations with regard to all Tax-Related Items are not

14.

 

Employees

made by the Participant with the Corporation and/or the Employer prior to the relevant taxable
event, the Corporation will satisfy such obligations as provided above in (3) of this paragraph.

     To avoid negative accounting treatment, the Corporation may withhold or account for
Tax-Related Items by considering applicable minimum statutory withholding amounts or other
applicable withholding rates. If the obligation for Tax-Related Items is satisfied by withholding
in Shares, for tax purposes, the Participant will be deemed to have been issued the full number of
Shares subject to the Award, notwithstanding that a number of the Shares are held back solely for
the purpose of paying the Tax-Related Items due as a result of any aspect of the Participant’s
participation in the Plan.

     Finally, the Participant shall pay to the Corporation or the Employer any amount of
Tax-Related Items that the Corporation or the Employer may be required to withhold or account for
as a result of the Participant’s participation in the Plan that cannot be satisfied by the means
previously described. The Corporation may refuse to issue or deliver the Shares or the proceeds of
the sale of Shares if the Participant fails to comply with his or her obligations in connection
with the Tax-Related Items.

     The Administrator shall be authorized to establish such rules, forms and procedures as it
deems necessary to implement the foregoing.

     7. Successors. This Statement of Terms and Conditions and the Award Agreements shall
be binding upon and inure to the benefit of any successor or successors of the Corporation.
“Participant” as used herein shall include the Participant’s Beneficiary.

     8. Delaware Law. The interpretation, performance, and enforcement of this Statement
of Terms and Conditions and all Award Agreements shall be governed by the laws of the State of
Delaware.

     9. Data Privacy. By accepting the Award, the Participant hereby explicitly and
unambiguously consents to the collection, use and transfer, in electronic or other form, of his or
her personal data as described in this document by and among, as applicable, the Employer and the
Corporation and its Affiliates for the exclusive purpose of implementing, administering and
managing participation in the Plan.

          The Participant understands that the Corporation and the Employer hold certain personal
information about the Participant, including, but not limited, his or her name, home address and
telephone number, date of birth, social insurance or other identification number, salary,
nationality, job title, any Shares or directorships held in the Corporation, details of all
Options, Restricted Stock, Restricted Stock Units, Performance Shares, Other Share-Based Awards, or
any other entitlement to Shares of stock awarded, canceled, exercised, vested, unvested or
outstanding in the Participant’s favor, for the purpose of implementing, administering and managing
the Plan (“Data”). The Participant understands that Data may be transferred to any third parties
assisting in the implementation, administration and management of the Plan, that these recipients
may be located in the Participant’s country or elsewhere, such as in the United States of America,
and that the recipient’s country may have different data privacy laws and protections than the
Participant’s country. The Participant understands that he or she

15.

 

Employees

may request a list with the names and addresses of any potential recipients of the Data by
contacting the local human resources representative. The Participant authorizes the recipients to
receive, possess, use, retain and transfer the Data, in electronic or other form, for the purposes
of implementing, administering and managing participation in the Plan, including any requisite
transfer of such Data as may be required to a broker or other third party with whom the Participant
may elect to deposit any Shares of stock acquired under the Plan. The Participant understands that
Data will be held only as long as is necessary to implement, administer and manage his or her
participation in the Plan. The Participant understands that he or she may, at any time, view Data,
request additional information about the storage and processing of Data, require any necessary
amendments to Data or refuse or withdraw the consents herein, without cost, by contacting in
writing the local human resources representative. The Participant understands, however, that
refusing or withdrawing consent may affect his or her ability to participate in the Plan. For more
information on the consequences of refusal to consent or withdrawal of consent, the Participant
understands that he or she may contact the local human resources representative.
