WATERS CORPORATION PERFORMANCE STOCK UNIT AWARD AGREEMENT

Exhibit 10.1

WATERS CORPORATION

2012 EQUITY INCENTIVE PLAN

PERFORMANCE STOCK UNIT AWARD AGREEMENT

THIS AGREEMENT dated as of [            ] between Waters Corporation, a corporation organized under the laws of the State of Delaware (the “Company”), and [            ] (the “Participant”), an employee of Waters Corporation.

1. Grant of Award. Pursuant and subject to the Company’s 2012 Equity Incentive Plan (as the same may be amended from time to time, the “Plan”), the Company hereby grants to the Participant an award (the “Award”) consisting of a target number of [            ] Performance Units (the “Target Award”) and such Performance Units, the “PSUs”). Each PSU represents the conditional right to receive, without payment but subject to the terms, conditions and limitations set forth in this Agreement and in the Plan, one share of the common stock, par value $.01 per share, of the Company (the “Stock”), subject to adjustment pursuant to Section 8 of the Plan in respect of transactions occurring after the date hereof. The percentage of the Target Award that may be earned by the Participant will be determined in accordance with Exhibit A hereto. The date of grant (the “Grant Date”) of this Award is [            ].

2. Earned PSUs. The PSUs shall become “Earned PSUs” following the end of the Performance Period to the extent earned in accordance with the performance criteria set forth on Exhibit A (the “Performance Criteria”), subject to the Compensation Committee certifying, in its sole discretion, the achievement of the Performance Criterion.

3. Vesting of Earned PSUs; Termination of Employment. No portion of the Award is vested as of the date hereof. The Earned PSUs (if any) shall vest in full on March 1, [            ] (the “Vesting Date”), subject to your continuous employment through this date. Notwithstanding the foregoing, in the event of a termination of employment due to your death prior to the Vesting Date, the PSUs shall not terminate upon such termination and shall instead remain outstanding and eligible to become Earned PSUs in accordance with the terms of Exhibit A and to vest on the Vesting Date. The number of Earned PSUs, if any, will be prorated based on the number of the days that have elapsed in the Performance Period from the first day of the Performance Period to the date of such termination of employment.

4. Change of Control. Notwithstanding anything contained in Section 9 of the Plan to the contrary:

(a) If, prior to the Performance Period End Date (as defined in Exhibit A), a Change of Control occurs, to the extent the PSUs are outstanding immediately prior to such Change of Control, the Compensation Committee shall determine the extent to which the Performance Criterion has been met as of the date such Change of Control is consummated treating the date of such Change of Control as the Performance Period End Date (solely for purposes of determining the extent to which the Performance Criterion has been met as of such date) and shall determine the number of Earned PSUs, if any. The number of Earned PSUs, if any, shall continue to vest based solely on time and shall vest on the Vesting Date, subject to your remaining in continuous employment through such date, except as otherwise provided in Section 4(b) below.

(b) (i) If (A) in connection with a Change of Control described in subsection (a) above the Earned PSUs are assumed or continued, or a new award is substituted for the

Earned PSUs, by the acquiror or survivor (or an affiliate of the acquiror or survivor), (B) you remain continuously employed through the date of the Change of Control, and (C) your employment is terminated by the Company without Cause or by you for Good Reason, in either case, within eighteen months following the Change of Control, the Earned PSUs will automatically vest in full upon such termination of employment.

(ii) If, in connection with a Change of Control described in subsection (a) above, the Earned PSUs are not assumed or continued, or a new award is not substituted for the Earned PSUs, by the acquiror or survivor (or an affiliate of the acquiror or survivor), the Earned PSUs will automatically vest in full upon the occurrence of such Change of Control and the Company shall deliver to you any shares in respect of Earned PSUs in a manner that will allow you to participate in the Change of Control on the same basis as other shareholders.

(c) In the event a Change of Control occurs following a termination of employment due to your death and prior to the Performance Period End Date, (i) the PSUs shall become Earned PSUs as provided for in Section 4(a) above, (ii) the Earned PSUs will automatically vest in full upon the occurrence of such Change of Control, and (iii) the Company shall deliver to you any shares in respect of Earned PSUs in a manner that will allow you to participate in the Change of Control on the same basis as other shareholders.

5. Delivery of Shares. Shares in respect of Earned PSUs that have become vested will be delivered to you as soon as practicable following vesting, but in any event no later than the March 15^th following the date the Earned PSUs become vested hereunder (or any earlier date, after vesting, required to avoid characterization as non-qualified deferred compensation under Section 409A of the Code). In connection with the delivery of shares of Stock in respect of Earned PSUs, par value will be deemed paid for each share by past services rendered by you.

6. Duration of Award and Termination of Employment. This Award will expire upon the earlier of (i) the delivery of all vested and Earned PSUs granted pursuant to this Agreement or (ii) your termination of employment or other association with the Company and its Affiliates for any reason other than death or as provided in Section 4(b)(i) above.

7. Transfer of Awards. You may not transfer this Award except by will or the laws of descent and distribution.

8. Incorporation of Plan Terms. Except as expressly provided herein, this Award is granted subject to all of the applicable terms and provisions of the Plan, including but not limited to the provision for acceleration of vesting of this Award set forth in Section 8 (Adjustment Provisions) and the limitations on the Company’s obligation to deliver shares of Stock upon settlement set forth in Section 10 (Settlement of Awards).
