SCHERING-PLOUGH CORPORATION
2006 STOCK INCENTIVE PLAN

(As Amended and Restated Effective as of January 1, 2009)

I. ESTABLISHMENT AND PURPOSE

1.1 Purpose. The purpose of this Schering-Plough Corporation 2006 Stock Incentive Plan (the “Plan”) is to enable Schering-Plough Corporation to achieve superior financial performance, as reflected in the performance of its Shares and other key financial or operating indicators by (i) providing incentives and rewards to certain Employees who are in a position to contribute materially to the success and long-term objectives of Schering-Plough, (ii) aiding in the recruitment and retention of Employees of outstanding ability and (iii) providing Employees an opportunity to acquire or expand equity interests in Schering-Plough, thus aligning the interests of such Employees with those of Schering-Plough’s shareholders. Schering-Plough expects that it will benefit from the added interest that such Employees will have in the welfare of Schering-Plough as a result of their ownership or increased ownership of Schering-Plough’s Shares.

1.2 Effective Date; Shareholder Approval. The Plan was originally effective as of May 19, 2006, subject to the approval of the Plan by the affirmative vote of the holders of a majority of the Shares present in person or by proxy and entitled to vote at the 2006 Annual Meeting of Shareholders of Schering-Plough, or any adjournment of such meeting. Any Awards granted under the Plan prior to the approval of the Plan by Schering-Plough’s shareholders, as provided herein, were contingent on such approval; if such approval is not obtained, the Plan would have had no effect, and any Awards granted under the Plan would have been rescinded. Schering-Plough’s shareholder approved the Plan at the 2006 Annual Meeting and the Plan became effective on May 19, 2006.

(ii) Timing of Grant. No Incentive Stock Option shall be granted under the Plan after the 10-year anniversary of earlier of (A) the date the Plan is adopted by the Board and (B) the date the Plan is approved by Schering-Plough’s shareholders.

(iii) Amount of Award. The aggregate Fair Market Value on the date of grant of the Shares with respect to which such Incentive Stock Options first become exercisable during any calendar year under the terms of the Plan for any Participant may not exceed $100,000. For purposes of this $100,000 limit, the Participant’s Incentive Stock Options under this Plan and all Plans maintained by Schering-Plough and its Affiliates and Subsidiaries shall be aggregated. To the extent any Incentive Stock Option first becomes exercisable in a calendar year and such limit would be exceeded, such Incentive Stock Option shall thereafter be treated as a Nonqualified Stock Option for all purposes.

(iv) Timing of Exercise. In the event that an Incentive Stock Option is exercised by a Participant more than three months after a Participant’s Termination of Employment (or more than 12 months after the Participant is Disabled), such Incentive Stock Option shall thereafter be treated as a Nonqualified Stock Option for all purposes. For this purpose, an Employee’s employment relationship shall be treated as continuing intact while the Employee is on military leave, sick leave or other bona fide leave of absence (such as temporary employment with the Government) duly authorized in writing by Schering-Plough if the period of such leave does not exceed three months or, if longer, so long as the Employee’s right to reemployment with Schering-Plough or an Affiliate or Subsidiary is guaranteed either by statute or by contract. If the period of leave exceeds three months and the Employee’s right to reemployment is not guaranteed either by statute or by contract, the employment relationship will be deemed to terminate on the first date immediately following such three-month period.

- 15 -

(v) Transfer Restrictions. In no event shall the Committee permit an Incentive Stock Option to be transferred by a Participant other than by will or the laws of descent and distribution, and any Incentive Stock Option granted hereunder shall be exercisable, during his or her lifetime, only by the Participant.

(h) No Repricing. Except as otherwise provided in Section 5.3, in no event shall the Committee decrease the Exercise Price of a Stock Option after the date of grant or cancel outstanding Stock Options and grant replacement Stock Options with a lower Exercise Price without first obtaining the approval of the holders of a majority of the Shares present in person or by proxy at a meeting of Schering-Plough’s shareholders and entitled to vote at such meeting.

4.5 Restricted Stock. The Committee may grant Restricted Stock under the Plan to such Employees as the Committee may from time to time select, in such amounts and subject to such terms, conditions and restrictions (including, without limitation, transfer restrictions) and Restriction Periods as the Committee, in its discretion, may determine and set forth in the Award Certificate. The Committee, in its discretion, may condition an Award of Restricted Stock on the Participant giving the representation described in Section 7.4.

(a) Payment of Restricted Stock. As soon as practicable after Restricted Stock is awarded, a certificate or certificates for all such Shares of Restricted Stock shall be registered in the name of the Participant and, at the discretion of Schering-Plough, be either (i) delivered to the Participant or (ii) held by Schering-Plough on behalf of the Participant until all restrictions have lapsed. The Participant shall thereupon have all the rights of a shareholder with respect to such Shares, including the right to vote and receive dividends or other distributions made or paid with respect to such Shares, except that such Shares shall be subject to the forfeiture provisions of clause (i) below. The Committee may, in its discretion, impose and set forth in the Award Certificate such other restrictions on Restricted Stock for such Restriction Period or Periods as it deems appropriate. Except as the Committee may otherwise determine, and subject to (1) the Committee’s authority under Section 3.2 to waive or amend any terms, conditions, limitations or restrictions of an Award, (2) Section 5.4 relating to Changes in Control and (3) the special forfeiture provisions of Section 7.2, such Shares shall be subject to the following provisions.

(i) Forfeiture and Lapse of Restriction. Shares of Restricted Stock shall be forfeited by a Participant upon the Participant’s Termination of Employment during the Restriction Period for any reason other than the Participant’s death, Disability or Termination Due to Business Divestiture. Subject to clause (ii) below and Section 5.4 relating to Changes in Control, restrictions on Shares of Restricted Stock shall lapse at the end of the Restriction Period set forth in the Award Certificate.

- 16 -

(ii) Accelerated Lapse. Notwithstanding the foregoing, all restrictions on Shares of Restricted Stock shall immediately lapse upon the death or Disability of the Participant. The Committee may, in its discretion, provide in the applicable Award Certificate that restrictions on Shares of Restricted Stock shall also lapse upon the Participant’s Retirement or Involuntary Termination.

(b) Legend. In order to enforce any restrictions that the Committee may impose on Restricted Stock, the Committee shall cause a legend or legends setting forth a specific reference to such restrictions to be placed on all certificates for Shares of Restricted Stock. As restrictions are released, a new certificate, without the legend, for the number of Shares with respect to which restrictions have been released shall be issued and delivered to the Participant as soon as possible thereafter.

4.6 Deferred Stock Units. The Committee may grant Deferred Stock Units under the Plan to those Employees whom the Committee may from time to time select, in such amounts and pursuant to such other terms and conditions that the Committee, in its discretion, may determine and set forth in the Award Certificate, subject to the following provisions.

(a) Deferred Stock Account. Deferred Stock Units awarded to a Participant shall be credited to a Deferred Stock Account established and maintained by Schering-Plough on behalf of the Participant. No Participant shall be a shareholder with respect to any Shares underlying Deferred Stock Units credited to his Deferred Stock Account, nor shall the Participant (or the Participant’s Beneficiary) have any right to or interest in any specific assets of Schering-Plough or its Affiliates or Subsidiaries, including any Shares reserved for issuance under the Plan, until such Shares are actually distributed to the Participant.

(b) Dividend Equivalents. Unless the Committee determines otherwise at the time of grant and sets forth in the applicable Award Certificate, in the event of Schering-Plough’s payment of dividends on Shares, Dividend Equivalents shall be applied as follows.

(i) Stock Dividends. Dividend Equivalents relating to stock dividends shall be credited to a Participant’s Deferred Stock Account as of the dividend payment date in the form of additional Deferred Stock Units, based on the Fair Market Value of a Share on the dividend payment date.

(ii) Non-Stock Dividends. Dividend Equivalents relating to dividends other than stock dividends shall be distributed immediately to the Participant as additional compensation on the dividend payment date.

(c) Payment of Shares. Subject to paragraph (d) below and Section 5.4 relating to Changes in Control, Deferred Stock Units shall be paid in Shares, at the rate of one Share per each Deferred Stock Unit, at such time or times and in such

- 17 -

manner as the Committee shall determine at the time of grant and set forth in the applicable Award Certificate, which can be either:

(i) Lump Sum. A single lump sum payable on a specified date not earlier than the six-month anniversary of the date the Deferred Stock Units were awarded to the Participant, or

(ii) Installments. In a set number of equal or unequal periodic installments commencing on a specified date not earlier than the six-month anniversary of the date the Deferred Stock Units were awarded to the Participant.

The timing and form of payment of Shares in settlement of Deferred Stock Units shall be set forth in the Award Certificate at the time of grant and, to the extent such Deferred Stock Units are subject to the requirements of Section 409A of the Code, shall not be subject to modification or acceleration by the Committee, except as provided in paragraph (d) below and in Section 5.4. The Committee, in its discretion, may condition the issuance of Shares in connection with Deferred Stock Units on the Participant giving the representation described in Section 7.4.

(d) Termination and Forfeiture. Unless the Award Certificate provides otherwise, and subject to (1) the Committee’s authority under Section 3.2 to waive or amend any terms, conditions, limitations or restrictions of an Award, (2) Section 5.4 relating to Changes in Control and (3) the special forfeiture provisions of Section 7.2, any undistributed Deferred Stock Units remaining in a Participant’s Deferred Stock Account shall be forfeited by the Participant upon the Participant’s Termination of Employment for any reason other than other than the death, Disability, Retirement, Termination Due to Business Divestiture or Involuntary Termination of the Participant.

(i) Death. Upon the death of a Participant prior to full payment of the Participant’s Deferred Stock Account, the remaining balance of the Participant’s Deferred Stock Account shall be paid in Shares to the Participant’s Beneficiary or, if none, to the legal representative of the Participant’s estate or to the person to whom the Participant’s Deferred Stock Unit payment rights are transferred under Participant’s will or by operation of law, in a single lump sum payment as soon as administratively feasible after the Participant’s death, but in no event later than the last day of the calendar year of the Participant’s death or, if later, the 15^th day of the third month following the Participant’s death. Schering-Plough shall be under no obligation to deliver Shares in satisfaction of a Deferred Stock Unit unless and until Schering-Plough is satisfied that the person or persons to whom the Shares are being transferred are the duly appointed executor(s) or administrator(s) of the deceased Participant or the person to whom the Deferred Stock Units have been transferred under the Participant’s will or by the applicable laws of descent and distribution.

- 18 -

(ii) Disability. In the event a Participant becomes Disabled prior to full payment of the Participant’s Deferred Stock Account, the remaining balance of the Participant’s Deferred Stock Account shall be paid in Shares at the scheduled time and in the scheduled manner set out in the applicable Award Certificate at the time of grant; provided, however that the Committee may determine at the time of grant and set forth in an Award Certificate that if the Participant becomes Disabled prior to the scheduled payment date or dates of the Deferred Stock Units, the remaining balance the Participant’s Deferred Stock Account shall be paid to the Participant in a single lump sum distribution as soon as administratively feasible after the date the Participant becomes Disabled, but in no event later than the last day of the calendar year in which the Participant becomes Disabled or, if later, the 15^th day of the third month following the date the Participant becomes Disabled.

(iii) Retirement. Upon the Retirement of a Participant prior to full payment of the Participant’s Deferred Stock Account, the Participant shall forfeit all unpaid Deferred Stock Units that were awarded to the Participant during the one-year period immediately preceding the Participant’s Retirement date and all other Deferred Stock Units remaining in the Participant’s Deferred Stock Account shall be paid at the scheduled time and in the scheduled manner set out in the applicable Award Certificate at the time of grant; provided, however that the Committee may determine at the time of grant and set forth in an Award Certificate that the entire unpaid balance of the a Participant’s Deferred Stock Account shall be forfeited upon the Participant’s Retirement. Alternatively, to the extent permitted under Section 409A of the Code, the Committee may determine at the time of grant and set forth in an Award Certificate that, in the event of the Participant’s Retirement prior to the scheduled payment date or dates of the Deferred Stock Units, the remaining balance the Participant’s Deferred Stock Account shall be paid to the Participant in a single lump sum distribution as soon as administratively feasible after the Participant’s Retirement date, but in no event later than the last day of the calendar year in which the Participant retires or, if later, the 15^th day of the third month following the date of the Participant’s Retirement. Notwithstanding the forgoing, if the Participant is a Section 409A Specified Employee on his or her Retirement date, payment may not be made earlier than the six-month anniversary of the Participant’s Retirement date.

(iv) Termination Due to Business Divestiture. Upon a Participant’s Termination Due to Business Divestiture prior to full payment of the Participant’s Deferred Stock Account, the remaining balance of the Participant’s Deferred Stock Account shall be paid in Shares at the scheduled time and in the scheduled manner set out in the applicable Award Certificate at the time of grant. Alternatively, to the extent permitted under Section 409A of the Code, the Committee may determine at the time of grant and set forth in an Award Certificate that, in the event of the Participant’s Termination Due to Business Divestiture prior to the scheduled payment date or dates of the Deferred Stock Units, the remaining balance the Participant’s Deferred Stock Account shall be

- 19 -

paid to the Participant in a single lump sum distribution as soon as administratively feasible after the Participant’s termination date, but in no event later than the last day of the calendar year of the Participant’s termination or, if later, the 15^th day of the third month following the date of the Participant’s termination. Notwithstanding the forgoing, if the Participant is a Section 409A Specified Employee on his or her termination date, payment may not be made earlier than the six-month anniversary of the Participant’s termination date.

(v) Involuntary Termination. Upon the Involuntary Termination of a Participant prior to full payment of the Participant’s Deferred Stock Account, the Participant shall forfeit —

(A) All unpaid Deferred Stock Units that were awarded to the Participant during the one-year period immediately preceding the Participant’s Involuntary Termination date; and

(B) A prorated portion of the remaining Deferred Stock Units under each Deferred Stock Unit Award determined by subtracting from the number of unpaid Deferred Stock Units remaining under such Award the product of (I) the number of unpaid Deferred Stock Units remaining under such Award, multiplied by (II) a fraction, the numerator of which is the number of full months worked by the Participant between the date of grant and the Involuntary Termination date, and the denominator of which is the total number of full months between the date of grant and the originally scheduled payment date.

All other Deferred Stock Units remaining in the Participant’s Deferred Stock Account shall be paid at the scheduled time and in the scheduled manner set out in the applicable Award Certificate at the time of grant.

(e) Payment Deferrals. Subject to the requirements of Section 409A of the Code, the Committee may from time to time and on a case by case basis permit a Participant to elect to defer payment of his Deferred Stock Units, or change the form of payment of Shares issued in connection with Deferred Stock Units. Elections to defer the payment date or change the form of payment shall be subject to the following limitations, which may not be waived by the Committee:

(i) Such election must be made, if at all, no less than 12 months prior to the originally scheduled payment date set out in the Award Certificate for the Deferred Stock Units with respect to which the election is made;

(ii) Such election may not take effect until at least 12 months after the date on which the election is made; and

(iii) Except with respect to an election to receive payment upon Disability, the first scheduled payment must be deferred pursuant to the election for a period

- 20 -

of at least five years from the original payment date set out in the Award Certificate for the Deferred Stock Units with respect to which the election is made.

For purposes of Section 409A of the Code, each scheduled installment payment under a Deferred Stock Unit Award shall be deemed to be a separate payment.

(f) Committee Discretion. Notwithstanding anything in the Plan to the contrary (including anything in Section 3.2 relating to the authority of the Committee or Section 5.4 relating to Changes in Control) in no event shall the Committee have discretion under the Plan to accelerate the payment date or deferred payment date of Deferred Stock Units, except to the extent permitted under Section 409A of the Code and applicable U.S. Treasury Department or Internal Revenue Service guidance issued in connection with Section 409A of the Code.

4.7 Other Stock-Based Awards. Subject to compliance with the requirements of Section 409A of the Code, the Committee may, from time to time, grant to an Employee Other Stock-Based Awards under the Plan. These Awards may include, among other things Shares, restricted stock options, stock appreciation rights that are settled in Shares, and phantom or hypothetical Shares. The Committee shall determine, in its discretion, the terms, conditions, restrictions and limitations, if any, that shall apply to Other Stock-Based Awards granted pursuant to this Section 4.7 (including whether Dividend Equivalents shall be credited or paid with respect to any such Award), which terms, conditions, restrictions and/or limitations shall be set forth in the Award Certificate. The Committee, in its discretion, may condition the delivery of Shares in connection with an Award under this Section 4.7 on the Participant giving the representation described in Section 7.4.

4.8 Performance Awards. The Committee may grant Performance Awards under the Plan only to such Employees as the Committee may from time to time select, in such amounts and subject to such terms and conditions as the Committee, in its discretion, may determine. Performance Awards granted under the Plan shall be subject to the following provisions.

(a) General. Performance Awards that are not Qualified Performance Awards shall be based on such Performance Cycles, Performance Measures and vesting or payout formulas (which may be the same as or different than those applicable to Performance Awards that are designated as Qualified Performance Awards) as the Committee, in its discretion, may establish for such purposes.

(b) Form of Payment. Performance Awards may be paid in cash, Shares, Stock Options, Restricted Stock, Deferred Stock Units, Other Stock-Based Awards or any combination of the foregoing in such proportions as the Committee may determine, in its discretion, and set forth in the Award Certificate. To the extent that a Performance Award is paid in Shares, Stock Options, Restricted Stock, Deferred Stock Units and/or Other Stock-Based Awards, the amount of each such form of

- 21 -

Award that is payable shall be based on the Fair Market Value of a Share on the date of grant, subject to such reasonable Restricted Stock and Deferred Stock Unit discount factors and/or Stock Option valuation methodologies as the Committee may, in its discretion, apply. Stock Options, Restricted Stock, Deferred Stock Units and Other Stock-Based Awards granted in connection with a Performance Award shall be subject to the provisions of Sections 4.4, 4.5, 4.6 and 4.7, respectively.

(c) Qualified Performance Awards. A Performance Award granted to a Covered Employee under the Plan may, at the discretion of the Committee, be designated as a Qualified Performance Award. Qualified Performance Awards under the Plan may be granted either separately or at the same time as Awards that are not designated as Qualified Performance Awards; provided, however, that in no event may the payment of an Award that is not a Qualified Performance Award be contingent upon the failure to attain a specific level of performance on the Performance Measure(s) applicable to a Qualified Performance Award for the same Performance Cycle. In the event the Committee designates an Award as a Qualified Performance Award, any determinations of the Committee pertaining to Performance Measures and other terms and conditions of such Qualified Performance Award (other than a determination under paragraph (iii)(D) below to reduce the amount of the Award) shall be in writing and made within the Qualified Performance Award Determination Period. A Performance Award that the Committee designates as a Qualified Performance Award shall be subject to the following additional requirements.

(i) Performance Cycles. Performance Awards that are designated as Qualified Performance Awards shall be awarded in connection with a Performance Cycle. The Committee shall determine the length of a Performance Cycle within the Qualified Performance Award Determination Period. In the event that the Committee determines that a Performance Cycle shall be a period greater than one fiscal year, a new Qualified Performance Award may be granted and a new Performance Cycle may commence prior to the completion of the Performance Cycle associated with the prior Qualified Performance Award.

(ii) Participants. Within the Qualified Performance Award Determination Period, the Committee shall determine the Covered Employees who shall be eligible to receive a Qualified Performance Award for such Performance Cycle.

(iii) Performance Measures; Targets; Vesting and Payout Formulas.

(A) Within the Qualified Performance Award Determination Period, the Committee shall fix and establish, in writing, (1) the Performance Measure(s) that shall apply to the Qualified Performance Award for the Performance Cycle; (2) the target amount of such Qualified Performance Award that shall be payable to each such Covered Employee; and (3) the vesting and/or payout formula for computing the actual amount of such Qualified Performance Award that shall become vested and/or payable with respect to each level of

- 22 -

attained performance. Towards this end, such vesting and/or payout formula shall, based on objective criteria, set forth for the applicable Performance Measure(s) the minimum level of performance that must be attained during the Performance Cycle before any such Qualified Performance Award shall become vested and/or payable and the percentage of the target amount of such Award that shall be vested and/or payable to each Covered Employee upon attainment of various levels of performance that equal or exceed the minimum required level.

(B) The Committee may, in its discretion, select Performance Measures that measure the performance of Schering-Plough or one or more business units, divisions, Affiliates or Subsidiaries of Schering-Plough. The Committee may select Performance Measures that are absolute or relative to the performance of one or more comparable companies or an index of comparable companies.

(C) In applying Performance Measures, the Committee may, in its discretion, exclude unanticipated, unusual or infrequently occurring items (including any event described in Section 5.3 and the cumulative effect of changes in the law, regulations or accounting rules), and may determine within the Qualified Performance Award Determination Period to exclude other items.

(D) Notwithstanding anything in this paragraph (c)(iii) to the contrary, the Committee may, on a case by case basis and in its sole discretion, reduce, but not increase, the amount of any Qualified Performance Award that is payable to a Covered Employee with respect to a Performance Cycle, provided, however, that no such reduction shall result in an increase in the dollar amount of any such Qualified Performance Award payable to any other Covered Employee.

(iv) Committee Certification. No Qualified Performance Award shall vest or be paid to a Covered Employee under the Plan unless and until the Committee certifies in writing the level of attainment of the applicable Performance Measure(s) for the applicable Performance Cycle.

(v) Limitation on Awards. Subject to Sections 5.1 and 5.3, the dollar value of any Qualified Performance Award payable in cash to any Covered Employee shall not exceed $3 million (or, in the case of the Chief Executive Officer, $6,000,000) for any 12-month Performance Cycle; provided that for any Performance Cycle that is the same as a performance period under the Operations Management Team Incentive Plan, such amounts shall serve as combined limits under both this Plan and the Operations Management Team Incentive Plan. For any Performance Cycle greater than 12 months in duration, this maximum will be adjusted proportionately.

- 23 -

(vi) Code Section 162(m). It is the intent of Schering-Plough that Qualified Performance Awards granted to Covered Employees under the Plan shall satisfy the applicable requirements of Code Section 162(m) and the regulations thereunder so that Schering-Plough’s tax deduction for Qualified Performance Awards is not disallowed in whole or in part by operation of Code Section 162(m). If any provision of this Plan pertaining to Qualified Performance Awards, or any Award to a Covered Employee under the Plan that the Committee designates as a Qualified Performance Award, would otherwise frustrate or conflict with such intent, that provision or Award shall be interpreted and deemed amended so as to avoid such conflict.

4.9 Substitute Awards. The Committee may make Awards under the Plan to Acquired Grantees through the assumption of, or in substitution for, outstanding stock-based awards previously granted to such Acquired Grantees. Such assumed or substituted Awards will be subject to the terms and conditions of the original awards made by the Acquired Company, with such adjustments therein as the Committee considers appropriate to give effect to the relevant provisions of any agreement for the acquisition of the Acquired Company. Any grant of Stock Options pursuant to this Section 4.9 will be subject to the rules set out in Section 424 of the Code and any final regulations published thereunder, regardless of whether the Stock Option is intended to be an Incentive Stock Option or a Nonqualified Stock Option.

4.10 Termination for Cause. Notwithstanding anything to the contrary herein, if a Participant incurs a Termination for Cause, then all of the Participant’s outstanding Awards under the Plan (whether or not vested or exercisable) will immediately be cancelled and forfeited and the special forfeiture provisions of Section 7.2 shall apply. The exercise of any Stock Option or the payment of any Award may be delayed, in the Committee’s discretion, in the event that a potential Termination for Cause is pending.

V. SHARES SUBJECT TO THE PLAN; ADJUSTMENTS

5.1 Shares Available. The Shares issuable under the Plan are authorized but unissued Shares or Shares held in Schering-Plough’s treasury. Subject to adjustment in accordance with Section 5.3, the total number of Shares with respect to which Awards may be issued under the Plan may not exceed 92,000,000 Shares, which includes the number of Shares that have been approved by Schering-Plough shareholders for issuance under the Prior Plan, but which have not been awarded under the Prior Plan as of the Effective Date and which are no longer available for issuance under Prior Plan for any reason (including without limitation, the discontinuance or termination of the Prior Plan). Subject to adjustment in accordance with Section 5.3, from such aggregate limit:

(a) No more than an aggregate of 46,000,000 Shares may be issued under Incentive Stock Options during the term of the Plan;

- 24 -

(b) No more than an aggregate of 46,000,000 Shares may be issued in the form of Restricted Stock, Deferred Stock Units or Other Stock-Based Awards payable in Shares during the term of the Plan; and

(c) The maximum aggregate number of Shares with respect to which Stock Options may be granted to any one Participant during any fiscal year of Schering-Plough may not exceed 3,000,000 Shares.

5.2 Counting Rules.

(a) Shares Counted. For purposes of determining the number of Shares remaining available for issuance under the Plan (including Shares originally approved under the Prior Plan, but made available for issuance under this Plan in accordance with Section 5.1), only Awards payable in Shares shall be counted. In addition, Shares that are tendered or withheld in payment of all or part of the Exercise Price of a Stock Option, or in satisfaction of the withholding obligations of an Award shall be counted against the remaining Shares and shall no longer be available for issuance under the Plan.

(b) Shares Not Counted. The following Shares relating to Awards under this Plan (or Awards under the Prior Plan that are outstanding as of the Effective Date) are not counted as issued Shares for purposes of determining the number of Shares remaining available for issuance under the Plan, and shall remain available for issuance under the Plan.

(i) Shares underlying awards that are settled in cash in lieu of Shares;

(ii) Shares underlying Awards that expire, are forfeited, cancelled or terminate for any other reason without the issuance of Shares;

(iii) Shares issued in connection with Awards that are assumed, converted or substituted as the result of Schering-Plough’s acquisition of an Acquired Company or the combination of Schering-Plough with another company; and

(iv) Shares of Restricted Stock that are forfeited and returned to Schering-Plough upon a Participant’s Termination of Employment.

5.3 Adjustments. If there is a change in the outstanding Shares by reason of any stock split, reverse stock split, dividend or other distribution (whether in the form of cash, Shares, other securities or other property), extraordinary cash dividend, recapitalization, split-up, spin-off, reorganization, combination, repurchase or exchange of Shares or other securities, the issuance of warrants or other rights to purchase Shares or other securities, or other similar corporate transaction or event, then in order to prevent dilution or enlargement of the benefits or potential benefits intended to be made available under the Plan, an adjustment in the number or kind of Shares that may be issued under the Plan, the number of Shares underlying an outstanding Award, the Exercise price of a Stock

- 25 -

Option or the number of Deferred Stock Units credited to a Deferred Stock Account will be made by the Committee and such adjustment will be conclusive and binding for all purposes under the Plan. Notwithstanding the foregoing, no adjustments shall be made with respect to Qualified Performance Awards granted to a Covered Employee to the extent such adjustment would cause the Award to fail to qualify as performance-based compensation under Section 162(m) of the Code.

5.4 Consequences of a Change in Control. Notwithstanding any other provision of the Plan, Awards that are outstanding as of the effective date of a Change in Control shall be subject to the following provisions.

(a) Replacement Awards. Any Award granted hereunder shall be deemed to apply to the securities, cash or other property (subject to adjustment by cash payment in lieu of fractional interests) to which a holder of the number of Shares equal to the number of Shares underlying the Participant’s Awards would have been entitled pursuant to the Change in Control, and proper provisions shall be made to ensure that this clause is a condition to any transaction that would result in a Change in Control; provided, however, that during the 60-day period beginning on the date of Change in Control, the Committee (or, if applicable, the board of directors of the entity assuming Schering-Plough’s obligations under the Plan) may, in its discretion, take any of the following actions with respect to each Award that is outstanding as of the effective date of Change in Control:

(i) Modify or adjust the Award to reflect the Change in Control; or

(ii) Cancel the Award and cause the acquiring or surviving corporation to replace it with an equivalent right after the Change in Control.

(b) Stock Options. All outstanding Stock Options that have not become exercisable as of the effective date of a Change in Control shall continue to become exercisable in accordance with the vesting schedule set out in the applicable Award Certificate. Notwithstanding the foregoing, in the event a Participant incurs an Involuntary Termination within two years after the effective date of a Change in Control, all of the Participant’s outstanding Stock Options shall become immediately vested and exercisable as of the date of such Involuntary Termination and shall remain exercisable for the full duration of the Stock Option’s original term, notwithstanding the Participant’s Termination of Employment. In addition, during the 60-day period beginning on the date of Change in Control, the Committee may, in its discretion, cancel all or a portion of a Participant’s remaining Stock Options and, in consideration of such cancellation, pay the Participant with respect to each Share issuable under the cancelled Stock Option an amount in cash equal to the amount by which the Change in Control Price exceeds the Exercise Price of the cancelled Stock Option.

(c) Deferred Stock Units. All Deferred Stock Units credited to a Participant’s Deferred Stock Account but not yet distributed as of the effective date of the

- 26 -

Change in Control shall be paid in Shares at the scheduled time and in the scheduled manner set out in the applicable Award Certificate at the time of grant. Notwithstanding the foregoing, in the event a Participant incurs an Involuntary Termination within two years after the effective date of a Change in Control, all Deferred Stock Units credited to a Participant’s Deferred Stock Account but not yet distributed as of the date of such Involuntary Termination shall become immediately vested and non-forfeitable and shall be distributed in a single lump sum cash payment, in lieu of Shares, as soon practicable thereafter (but in no event more than 30 days after the date of such Involuntary Termination) at a dollar value per Deferred Stock Unit equal to the Fair Market Value of a Share on the date of termination.

(d) Restricted Stock and Other Stock-Based Awards. All restrictions and conditions on any Shares of Restricted Stock or Other Stock-Based Awards shall continue to apply for the duration of the Restriction Period. Notwithstanding the foregoing, in the event a Participant incurs an Involuntary Termination within two years after the effective date of a Change in Control, all restrictions and conditions on any Shares of Restricted Stock or Other Stock-Based Awards shall immediately lapse or be deemed satisfied, as the case may be, as of the date of such Involuntary Termination and all such Awards shall become vested and non-forfeitable as of such date.

(e) Performance Awards. The Committee shall set out in the Award Certificate for each Performance Award the terms and conditions that shall apply to such Performance Award in the event the Award is outstanding as of the effective date of a Change in Control.

5.5 Fractional Shares. No fractional Shares shall be issued under the Plan. In the event that a Participant acquires the right to receive a fractional Share under the Plan, such Participant shall receive, in lieu of such fractional Share, cash equal to the Fair Market Value of the fractional Share as of the date of settlement.

VI. AMENDMENT AND TERMINATION

6.1 Amendment. The Plan may be amended at any time and from time to time by the Board without the approval of shareholders of Schering-Plough, except that no material revision to the terms of the Plan will be effective without first obtaining the approval of the amendment by the holders of a majority of the Shares present in person or by proxy at a meeting of Schering-Plough’s shareholders and entitled to vote at such meeting. A revision is “material” for this purpose if, among other changes, it (a) materially increases the number of Shares that may be issued under the Plan (other than an increase pursuant to Section 5.3 of the Plan), (b) changes the types of Awards available under the Plan, (c) expands the class of persons eligible to receive Awards under the Plan, (d) extends the term of the Plan, (e) decreases the Exercise Price at which Stock Options may be granted, (f) reduces the Exercise Price of outstanding Stock Options, or (g) results in the replacement of outstanding Stock Options with new Awards that have an Exercise Price

- 27 -

that is lower than the Exercise Price of the replaced Stock Options. No amendment of the Plan made without the Participant’s written consent may adversely affect any right of a Participant with respect to an outstanding Award. Notwithstanding the foregoing, this Plan is intended to incorporate all applicable requirements of Section 409A of the Code and guidance issued thereunder by the U.S. Treasury Department and the Internal Revenue Service, and the Plan will be deemed to be amended as necessary to comply with those requirements.

6.2 Termination. The Plan shall terminate upon the earlier of the following dates or events to occur:

(a) The adoption of a resolution of the Board terminating the Plan; or

(b) December 31, 2011.

No Awards shall be granted under this Plan after it has been terminated. However, the termination of the Plan shall not alter or impair any of the rights or obligations of any person, without such person’s consent, under any Award theretofore granted under the Plan. After the termination of the Plan, any previously granted Awards shall remain in effect and shall continue to be governed by the terms of the Plan and the applicable Award Certificate.

VII. GENERAL PROVISIONS

7.1 Nontransferability of Awards. No Award under the Plan shall be subject in any manner to alienation, anticipation, sale, assignment, pledge, encumbrance or transfer, and no other persons will otherwise acquire any rights therein, except as provided below.

(a) Any Award may be transferred by will or by the laws of descent or distribution.

(b) The Committee may provide in the Award Certificate that all or any part of the vested portion of a Nonqualified Stock Option may, subject to the prior written consent of the Committee, be transferred to one or more of the following classes of donees:

(i) a family member;

(ii) a trust for the benefit of a family member; or

(iii) a limited partnership whose partners are solely family members, or any other legal entity set up for the benefit of family members.

For purposes of this paragraph (b), a family member means a Participant’s spouse, children, grandchildren, parents, grandparents, siblings, nieces, nephews, grandnieces and grandnephews, including adopted, in-laws and step family members.

(c) Any transferred Award will be subject to all of the same terms and conditions as provided in the Plan and the applicable Award Certificate. The Participant or the Participant’s estate will remain liable for any withholding tax that may be imposed by any federal, state or local tax authority. The Committee may, in its discretion, disallow all or a part of any transfer of an Award pursuant to paragraph (b) above unless and until the Participant makes arrangements satisfactory to the Committee for the payment of any withholding tax. The Participant must immediately notify the Committee, in the form and manner required by the Committee, of any proposed transfer of an Award pursuant to paragraph (b). No transfer will be effective until the Committee consents to the transfer in writing.

(d) Except as otherwise provided in the Award Certificate, any Nonqualified Stock Option transferred by a Participant pursuant to this paragraph (d) may be exercised by the transferee only to the extent that the Award would have been exercisable by the Participant had no transfer occurred. The transfer of Shares upon exercise of the Award will be conditioned on the payment of any withholding tax.

(e) Restricted Stock may be freely transferred after the restrictions lapse or are satisfied and the Shares are delivered; provided, however, that Restricted Stock awarded to an affiliate of Schering-Plough may be transferred only pursuant to Rule 144 under the Securities Act, or pursuant to an effective registration for resale under the Securities Act. For purposes of this paragraph (e), “affiliate” will have the meaning assigned to that term under Rule 144.

(f) In no event may a Participant transfer an Incentive Stock Option other than by will or the laws of descent and distribution.

7.2 Special Forfeiture Provision. Except as otherwise provided in the current employment agreement between Schering-Plough and the relevant Employee (which agreement shall take precedent over this Section 7.2), and if the Committee, in its discretion, provides otherwise in the applicable Award Certificate, if a Participant either —

(a) incurs a Termination for Cause or

(b) incurs a Termination of Employment for any reason other than other than death, Disability, Retirement, Termination Due to Business Divestiture or Involuntary Termination and, within one year after such Termination of Employment, without prior written approval of the Committee, enters into an employment or consulting arrangement (including service as an agent, partner, stockholder, consultant, officer or director) with any entity or person engaged in any business in which Schering-Plough or its Affiliates or Subsidiaries is engaged that, in the sole judgment of the Committee, is competitive with Schering-Plough

- 29 -

or any Affiliate or Subsidiary, then the Participant shall forfeit and return to Schering-Plough —

(i) the amount of any profit realized upon the exercise of any Stock Options at any time on or after the date that is ninety (90) days immediately prior to the date of the Participant’s Termination of Employment;

(ii) all shares of Restricted Stock that are not then vested or which vested during the three-month period immediately preceding such Termination of Employment; and

(iii) all Shares issued to the Participant in payment of the Participant’s Deferred Stock Units during the three-month period immediately preceding such Termination of Employment.

7.3 Withholding of Taxes. The Committee, in its discretion, may satisfy a Participant’s tax withholding obligations by any of the following methods or any method as it determines to be in accordance with the laws of the jurisdiction in which the Participant resides, has domicile or performs services.

(a) Stock Options. As a condition to the delivery of Shares pursuant to the exercise of a Stock Option, the Committee may require that the Participant, at the time of exercise, pay to Schering-Plough by cash, certified check, bank draft, wire transfer or postal or express money order an amount sufficient to satisfy any applicable tax withholding obligations. The Committee may, however, in its discretion, accept payment of tax withholding obligations through any of the Exercise Price payment methods described in Section 4.4(f).

(b) Other Awards Payable in Shares. The Participant shall satisfy the Participant’s tax withholding obligations arising in connection with the release of restrictions on Restricted Stock or the payment of Deferred Stock Units or Other Stock-Based Awards by payment to Schering-Plough by cash, certified check, bank draft, wire transfer or postal or express money order an amount sufficient to satisfy any applicable tax withholding obligations, provided that the format is approved by Schering-Plough or a designated third-party administrator. Notwithstanding the foregoing, subject to the requirements of applicable law, Schering-Plough may also satisfy the Participant’s tax withholding obligations by other methods, including selling or withholding Shares that would otherwise be available for delivery, provided that the Committee has specifically approved such payment method in advance.

(c) Cash Awards. Schering-Plough may satisfy a Participant’s tax withholding obligations arising in connection with the payment of any Award in cash by withholding cash from such payment.

7.4 Investment Representation. As a condition to any distribution of Shares pursuant to Awards under the Plan, Schering-Plough may require a Participant to represent in writing that such Shares are being acquired for the Participant’s own account for investment and not with a view to, or for sale in connection with, the distribution of any part thereof.

7.5 Code Section 83(b) Elections. Neither Schering-Plough, any Affiliate or Subsidiary, nor the Committee shall have any responsibility in connection with a Participant’s election, or attempt to elect, under Code Section 83(b) to include the value of a Restricted Stock Award in the Participant’s gross income for the year of payment. Any Participant who makes a Code Section 83(b) election with respect to any such Award shall promptly notify the Committee of such election and provide the Committee with a copy thereof.

7.6 Beneficiary Designations. Designations of Beneficiaries by a Participant shall be made in writing and filed with Schering-Plough in such form and in such manner as the Committee may from time to time prescribe. A Participant may change his or her Beneficiaries in the same manner at any time prior to the death of the Participant. If a Participant dies without having designated any surviving Beneficiaries, the Participant’s remaining interests in Awards under the Plan shall be distributed to the legal representative of his estate or in accordance with the Participant’s will.

7.7 No Implied Rights. The establishment and operation of the Plan, including eligibility as a Participant, shall not be construed as conferring any legal or other right upon any Employee for the continuation of his or her employment for any Performance Cycle or any other period. Schering-Plough expressly reserves the right, which may be exercised at any time and in Schering-Plough’s sole discretion, to discharge any individual and/or treat him or her without regard to the effect which such treatment might have upon him or her as a Participant in the Plan.

7.8 No Obligation to Exercise Options. The granting of a Stock Option shall impose no obligation upon the Participant to exercise such Stock Option.

7.9 No Rights as Shareholders. A Participant granted an Award under the Plan shall have no rights as a shareholder of Schering-Plough with respect to the Award unless and until such time as certificates for the Shares underlying the Award are registered in such Participant’s name. The right of any Participant to receive an Award by virtue of participation in the Plan shall be no greater than the right of any unsecured general creditor of Schering-Plough.

7.10 Indemnification of Committee. Schering-Plough shall indemnify, to the full extent permitted by law, each person made or threatened to be made a party to any civil or criminal action or proceeding by reason of the fact that he, or his testator or intestate, is or was a member of the Committee or a delegate of the Committee so acting.

7.11 No Required Segregation of Assets. Neither Schering-Plough nor any Affiliate or Subsidiary shall be required to segregate any assets that may at any time be represented by Awards granted pursuant to the Plan. In no event shall any interest be paid or accrued on any Award, including unpaid installments of an Award.

7.12 Nature of Payments. All Awards made pursuant to the Plan are in consideration of services for Schering-Plough or its Affiliates or Subsidiaries. Any gain realized pursuant to Awards under the Plan constitutes a special incentive payment to the Participant and shall not be taken into account as compensation for purposes of any of the employee benefit plans of Schering- Plough or any Affiliate or Subsidiary except as may otherwise be specifically provided in the applicable employee benefit plan.

7.13 Compliance with Applicable Law. The obligations of Schering-Plough to issue or transfer Shares pursuant to Awards shall be subject to (a) the effectiveness of a registration statement under the Securities Act of 1933, as amended, with respect to the Shares, (b) the condition that the Shares be listed (or authorized for listing upon official notice of issuance) upon each stock exchange upon which Shares are listed and (c) compliance with all applicable laws and approvals by all governmental or regulatory agency as may be required. With respect to Reporting Persons, it is the intent of Schering-Plough that the Plan and all transactions under the Plan comply with all applicable provisions of Rule 16b-3 or its successors under the Exchange Act. If any provision or this Plan or of any grant of an Award would otherwise frustrate or conflict with such intent, that provision shall be interpreted and deemed amended so as to avoid such conflict. No Participant will be entitled to a grant, exercise, transfer or payment of any Award if the grant, exercise, transfer or payment would violate the provisions of the Sarbanes-Oxley Act of 2002 or any other applicable law. In addition, it is the intent of Schering-Plough that the Plan and applicable Awards under the Plan comply with the applicable provisions of Sections 162(m) and 422 of the Code, and to the extent an Award is subject to the requirements of Section 409A of the Code, it is the intent of Schering-Plough that the Award be administered in a manner that satisfies such requirements. To the extent that any legal requirement of Section 16 of the Exchange Act or Section 162(m), 409A or 422 of the Code as set forth in the Plan ceases to be required under such Section, that Plan provision shall cease to apply. The Committee may revoke any Award if it is contrary to law or modify a Award (to the extent permitted by applicable law) to bring it into compliance with any valid and mandatory government regulation.

7.14 Headings. Section and paragraph headings are for reference only. In the event of a conflict between the title and content of a section or paragraph, the content shall control.

7.15 Governing Law; Severability. The Plan and all determinations made and actions taken thereunder shall be governed by the internal substantive laws, and not the choice of law rules, of the State of New Jersey and construed accordingly, to the extent not superseded by applicable federal law. If any provision of the Plan shall be held unlawful or otherwise invalid or unenforceable in whole or in part, the unlawfulness, invalidity or
