Baxalta Incorporated Equity Plan July 1,2015

Exhibit 10.17

Baxalta Incorporated

Equity Plan

July 1, 2015

This Equity Plan (the “Plan”) has been adopted by the Compensation Committee (the “Committee”) of the Board of Directors (the “Board”) of Baxalta Incorporated (“Baxter”), effective as of July 1, 2015.

For avoidance of doubt, all grants made under this Plan shall be made on or after the date on which the stock Baxalta is distributed to the shareholders of Baxter International Inc. and shall not be subject to adjustment in the manner described in the Employee Matters Agreement between Baxter International Inc. and Baxalta.

Participants in this Plan (each a “Participant”) shall be employees of Baxalta or its subsidiaries (the “Company”) to whom awards of equity are made by the Committee, or any person to whom the Committee delegates the authority to make awards, under this Plan.

Each grant of equity (an “Award”) shall be made pursuant to and for the purposes stated in the Baxalta Incorporated 2015 Incentive Plan, or such other stock incentive plan as may be designated by the Committee (the “Program”). Unless otherwise indicated, terms defined in the Program shall have the same meaning in this Plan.

This Plan provides terms that apply to awards of stock options (“Options”) and restricted stock units (“RSUs”). An award to any given Participant may be only Options, only RSUs, or any combination of Awards available under the Program.

Participants receive grant communication letters notifying them of their Awards. The Program and this Plan provide the definitive terms of each Award; provided that a grant communication letter may include alternative terms with respect to vesting, in which case the vesting terms in the grant communication letter shall govern.

The grant date for an Award shall be the date of approval thereof by the Incentive Committee, or for eligible French employees, as soon thereafter as practicable pursuant to applicable French law as provided in the attached French Addendum, which shall govern such grants (the “Grant Date”).

The purchase price for each share of Common Stock subject to an Option shall be the Fair Market Value of a share of Common Stock on the Grant Date. Options are not intended to qualify as an Incentive Stock Option within the meaning of section 422 of the United States Internal Revenue Code, as amended (the “Code”).

Baxalta has not selected any country as its home member state under the European Union Directive 2003/71/EC, and the grant of Awards pursuant to this Plan is simultaneous.

4.1. Except for Options granted to employees of the Company’s subsidiaries in France, Options shall become exercisable as follows: (i) one-third on the first anniversary of the Grant Date, (ii) one-third on the second anniversary of the Grant Date, and (iii) the remainder on the third anniversary of the Grant Date. Options granted to employees of the Company’s subsidiaries in France shall become exercisable on the fourth anniversary of the Grant Date. If Options would become exercisable on a date that is not a business day, they will become exercisable on the next business day. A business day is any day on which the Company’s Common Stock is traded on the New York Stock Exchange. After Options become exercisable (in each case, in whole or in part) and until they expire, the Options may be exercised in whole or in part in the manner specified by the Committee. Under no circumstances may Options be exercised after they have expired. Shares of Common Stock may be used to pay the purchase price for shares of Common Stock to be acquired upon exercise of Options or fulfill any tax withholding obligation, subject to any requirements or restrictions specified by the Committee.

4.2. If a Participant’s employment with the Company terminates before the Participant’s Options becomes exercisable, the Options will expire when the Participant’s employment with the Company terminates, except (i) in connection with a Qualifying Retirement or death or disability (each as outlined below) or (ii) if the Participant is rehired by the Company within ninety days of termination, in which case the Participant shall be construed to have been continuously employed by the Company for purposes of vesting and exercise.

4.3. If a Participant’s employment with the Company terminates after the Participant’s Options become exercisable, the Options will not expire immediately but will remain exercisable. Subject to Section 4.6, and except in the event of a Qualifying Retirement (as provided in Section 4.4), the Options will expire ninety days after the Participant’s employment with the Company terminates. If the Participant dies or becomes disabled during the ninety-day period, the Options will expire on the fifth anniversary of the termination date.

4.4. If the employment of a Participant who is at least 65 years of age, or at least 55 years of age with at least 10 years of employment with the Company (including prior employment with Baxter International Inc. or its subsidiaries), is terminated other than for Cause or by reason of the Participant’s death or disability (a “Qualifying Retirement”) then (i) if the date of such termination is after the calendar year of the Grant Date, the Options shall continue to vest as provided in Section 4.1, or (ii) if the date of such termination is in the calendar year of the Grant Date, a portion of the Options shall continue to vest as provided in (i), which portion shall be determined as follows: (# shares covered by Option award) * (# of months worked in that year, rounded to nearest whole month) / 12. Subject to Section 4.6, the Participant’s Options (whether vesting pursuant to (i) or (ii) or previously vested) will expire on the fifth anniversary of the termination date.

2

4.5. If the employment of a Participant is terminated due to death or disability, then (i) if the date of such termination is after the calendar year of the Grant Date, the Options shall vest immediately, or (ii) if the date of such termination is in the calendar year of the Grant Date, a portion of the Options shall vest immediately, which portion shall be determined as follows: (# shares covered by Option award) * (# of months worked in that year, rounded to nearest whole month) / 12. Subject to Section 4.6, the Participant’s Options (whether vesting pursuant to (i) or (ii) or previously vested) will expire on the fifth anniversary of the termination date.

4.6. Options that have not previously expired will expire at the close of business on the tenth anniversary of the Grant Date; provided, however, that Options granted to employees residing in Switzerland on the Grant Date shall expire on the eleventh anniversary of the Grant Date. If Options would expire on a date that is not a business day, they will expire at the close of business on the last business day preceding that date. A business day is any day on which the Common Stock is traded on the New York Stock Exchange.

4.7. Except as the Committee may otherwise provide, Options may only be exercised by the Participant, the Participant’s legal representative, or a person to whom the Participant’s rights in the Options are transferred by will or the laws of descent and distribution.

4.8. A transfer of employment within the Company will not constitute a termination of employment within the meaning of the Plan.

4.9. A transfer of employment to a company that assumes an Option or issues a substitute option in a transaction to which Section 424 of the Code applies will not constitute a termination of employment within the meaning of the Plan.

4.10. Except to the extent that it would cause the Option to be subject to Section 409A of the Code, the Committee may, in its sole discretion and without receiving permission from any Participant, substitute stock appreciation rights (“SARs”) for any or all outstanding Options. Upon the grant of substitute SARs, the related Options replaced by the substitute SARs shall be cancelled. The grant price of the substitute SARs shall be equal to the Option Price of the related Options, the term of the substitute SARs shall not exceed the term of the related Options, and the terms and conditions applicable to the substitute SARs shall otherwise be substantially the same as those applicable to the related Options replaced by the substitute SARs. Upon exercise, the SARs will be settled in Common Stock.

5.1. RSUs are subject to being earned and vested on the third anniversary of the Grant Date (as applicable, the “Vesting Date”). If RSUs would become earned and vested on a date that is not a business day, the next business day shall be the Vesting Date. The Company will deliver or otherwise make available to the Participant within 2¹/₂ months following the applicable Vesting Date one share of Common Stock for each RSU that vests.

5.2. If a Participant’s employment with the Company terminates before an RSU Vesting Date, the RSU will be forfeited when the Participant’s employment with the Company terminates, except (i) in connection with a Qualifying Retirement or death or disability (each as outlined below), or (ii) if the Participant is rehired by the Company within ninety days of termination, in which case the Participant shall be construed to have been continuously employed by the Company for purposes of vesting and payout.

3

5.3. If the employment of a Participant terminates in a Qualifying Retirement then (i) if the date of such termination is after the calendar year of the Grant Date, the RSUs will remain eligible for payout on the terms provided in Section 5.1, or (ii) if the date of such termination is in the calendar year of the Grant Date a portion of the RSUs shall remain eligible for payout on the terms provided in Section 5.1, which portion shall be determined as follows: (# RSUs awarded) * (# of months worked in that year, rounded to nearest whole month) / 12.

5.4. If the employment with the Company of a Participant is terminated due to death or disability, the RSUs shall vest as follows: (i) if the date of such termination is after the calendar year of the Grant Date, all the RSUs shall pay out within sixty days, or (ii) if the date of such termination is in the calendar year of the Grant Date a portion of the RSUs shall pay out as provided in (i), which portion shall be determined as follows: (# RSUs awarded) * (# of months worked in that year, rounded to nearest whole month) / 12.

5.5. The RSUs shall not be transferable and may not be sold, assigned, pledged, hypothecated or otherwise encumbered.

5.6. A transfer of employment within the Company will not constitute a termination of employment within the meaning of the Plan.

5.7. Until the shares of Common Stock have been delivered or otherwise made available as provided in Section 5.1, the Participant shall not be treated as a shareholder as to those shares of Common Stock relating to the RSUs. Notwithstanding the foregoing, the Participant shall be permitted to receive additional RSUs with respect to the RSUs based upon the dividends and distributions paid on shares of Common Stock to the same extent as if each RSU were a share of Common Stock, which additional RSUs shall be delivered or made available at the same time and to the same extent as the RSUs to which they relate or as otherwise determined by the Company.

In the event of a Change in Control of Baxalta, the vesting of outstanding Awards shall be as determined under the Program.

Except as specifically provided in the Plan, in the event of any inconsistency between the Plan and the Program, the Program will control, but only to the extent such provisions will not violate the provisions of section 409A of the Code.
