EXHIBIT 10.2

ENTEGRIS, INC.
2015 Performance Share Award Agreement

In consideration of services rendered to Entegris, Inc. (the “Company”), the
Company may periodically make equity incentive awards consisting of performance
based restricted stock units with respect to the Company’s Common Stock $0.01
par value (“Stock”) to certain key employees, non-employee directors,
consultants or advisors of the Company under the Company’s 2010 Stock Plan (the
“Plan”). Any key employee, non-employee director, consultant or advisor (a
”Participant”) who receives a performance based restricted stock unit award (the
“Award”) is notified either in writing or via email and the Award is credited to
the Participant’s account as reflected on the Participant’s Overview tab under
the Restricted Stock Plan section on the Morgan Stanley Stock Plan Connect web
page found at https://www.stockplanconnect.com. By clicking on the “Accept”
button for the Award in the Restricted Stock Plan section on the Overview tab or
by otherwise receiving the benefits of the Award, Participant: (i) acknowledges
that Participant has received a copy of the Plan, of the related prospectus
providing information concerning awards under the Plan and of the Company’s most
recent Annual Report on Form 10-K; and (ii) accepts the Award and agrees with
the Company that the Award is subject to the terms of the Plan and to the
following terms and conditions:
Article I - PERFORMANCE BASED RESTRICTED STOCK UNIT AWARD
1.1.
Award Date. This Agreement shall take effect as of the date specified in the
Restricted Stock Plan section on the Overview tab as the Award Date provided to
you online at www.stockplanconnect.com (the “Award Date”).

1.2.
Performance Based Restricted Stock Units Subject to Award. The Award consists of
that number of performance based restricted stock units (the “PRSU”) with
respect to the Stock that has been approved for the Award to Participant by the
Administrator as the target number of PRSUs (“Target PRSUs”);. The Target PRSUs
shall be subject to increase or decrease in accordance with Sections 1.3 and 1.4
below. Each PRSU is equivalent to one share of the Stock. The Participant’s
rights to the PRSU are subject to the restrictions described in this Agreement
and in the Plan (which is incorporated herein by reference with the same effect
as if set forth herein in full) in addition to such other restrictions, if any,
as may be imposed by law.

1.3.
Earned Performance Based Restricted Stock Units. The number of PRSUs earned
under this Agreement (the “Earned PRSUs”) shall be equal to the Target PRSUs
multiplied by the TSR Performance Multiplier (as defined herein). The “TSR
Performance Multiplier” will be determined by comparing the Company’s total
stockholder return to the total stockholder return of each of the companies in
the Comparator Peer Group (as set forth below) over the period commencing on the
Award Date and ending on the third anniversary of the Award Date (the
“Performance Period”) to determine the Company’s TSR ranking against the
Comparator Group. For purposes of computing total stockholder return: (i) any
dividends paid by the Company or the companies in the Comparator Group shall be
treated as having been reinvested; and (ii) the beginning stock price will be
the average closing stock price over the 20 trading days ending on the Award
Date and the ending stock price will be the average closing stock price over the
20 trading days ending on the last day of the Performance Period.

1.4.
Calculation of the TSR Performance Multiplier. The TSR Performance Multiplier
will be calculated as set forth in the following table based upon the Company’s
total stockholder return over the Performance Period when ranked against the
total stockholder return over the Performance Period of each of the companies in
the Comparator Peer Group:

Company TSR Percentile Rank
TSR Performance Multiplier
Below 25th percentile
0
25th percentile
50%
50th percentile
100%
75th percentile or above
150%

If the Company’s total stockholder return percentile rank during the Performance
Period is between the 25th and the 50th percentiles or 50th and 75th
percentiles, the TSR Performance Multiplier will be determined using straight
line interpolation based on the actual percentile ranking. As used herein, the
“Comparator Peer Group” consists of those companies that are in the Philadelphia
Semiconductor Index on the Award Date, subject to

--------------------------------------------------------------------------------

EXHIBIT 10.2

certain adjustments as may be approved by the Administrator relating to any
mergers and bankruptcies of the companies included in that Index. The Award
shall be subject to the following limitations: (i) if the Company’s absolute
total shareholder return is negative then the maximum number of shares that may
be earned is the Target PRSUs; and (ii) in no event may the value of the Award
at vesting exceed 300% of the value of the Target PRSUs on the Award Date; the
number of PRSUs vested shall be reduced to meet the foregoing absolute dollar
cap.
1.5.
Vesting of PRSUs. The term "vest" as used herein with respect to any PRSU means
the lapsing of the restrictions described herein with respect to such PRSU. The
Award shall not be vested as of the Award Date and shall be forfeitable by the
Participant without consideration or compensation in accordance with Section 1.6
below unless and until otherwise vested pursuant to the terms of this Agreement.
The Participant has no rights, partial or otherwise, in the Award and/or any
Stock subject thereto unless and until the Award has been earned pursuant to
Section 1.3 and vested pursuant to this Section 1.5. A number of PRSUs equal to
the Earned PRSUs will become 100% vested (referred to as “Vested Units”) on the
last day of the Performance Period (the “Maturity Date”), provided that the
Participant remains continuously employed by the Company, an Affiliate, or a
Subsidiary through the Maturity Date. Each Vested Unit shall be settled by the
delivery of one share of Stock (subject to adjustment under the Plan).
Settlement will occur as soon as practicable following certification by the
Administrator of the number of Earned PRSUs and passage of the Maturity Date
(or, if earlier, the date the Award becomes vested pursuant to the terms of
Section 1.7 below), but in no event later than the earlier of (i) 90 days
following the Maturity Date (or such earlier date that the Award becomes
vested), or (ii) March 15th of the year following the year in which the Award
becomes vested. No fractional Shares shall be issued pursuant to this Agreement.

1.6.
Forfeiture Risk. Except as provided in Section 1.7 below, if the Participant
ceases to be employed or retained by the Company or an Affiliate for any reason
any then outstanding and PRSU that is not a Vested Unit acquired by the
Participant hereunder shall be automatically and immediately forfeited. The
Participant hereby appoints the Company as the attorney-in-fact of the
Participant to take such actions as may be necessary or appropriate to
effectuate the cancellation of a forfeited PRSU.

1.7.
Early Vesting of PRSUs. This Section sets forth the exclusive circumstances
under which the Participant may become entitled to Vested Units even though he
or she is not employed through the Maturity Date: (i) If a Participant dies,
incurs a total and permanent disability (as that term is defined in the
company’s disability insurance policy in effect on the award date), or
terminates employment on account of retirement from employment with the Company
or an Affiliate at age 65 with ten consecutive years of employment with the
Company or an Affiliate, prior to the Maturity Date; then, in such event, the
Administrator may, in its sole discretion, allow all or such portion of the
Target PRSUs to become Vested Units or make such other provision as it deems
appropriate. If the Administrator does not take any such discretionary action,
then the Target PRSUs shall be forfeited in accordance with Section 1.6; and
(ii) in the event of a Change in Control where the Award is not continued or
assumed by a public company, the Earned PRSU, to the extent earned pursuant to
the next sentence, shall be fully vested immediately prior to the Change in
Control. The number of Earned PRSUs at the time of a Change in Control shall be
determined as of the date such Change in Control is consummated, rather than the
Maturity Date (as defined in Section 1.5), with the number of Earned PRSUs
determined as set forth in Section 1.4 above, based upon the Company’s total
stockholder return and the total stockholder return of each of the companies in
the Comparator Peer Group through the date of the Change in Control (and, with
respect to the Company, instead of the 20-business day average, taking into
account the consideration per share to be paid in the Change in Control
transaction), provided, however, that in the event that the Change in Control
occurs during the first year following the Award Date, then the number of Earned
PRSUs shall be fixed at the number of Target PRSUs; or (iii) In the event of a
Change in Control where the Award is continued or assumed by a public company,
then payment of the Earned PRSUs calculated in accordance with clause (ii)
above, shall continue to be contingent on the Participant’s employment through
the Maturity Date unless there is a Qualifying Termination within two years
following the Change in Control. If a Qualifying Termination occurs, the
restrictions on all unvested Earned PRSUs shall immediately lapse. The
provisions of clauses (ii) and (iii) shall govern the Award notwithstanding the
provisions of any Executive Change In Control Termination Agreement that may
exist between the Company or an Affiliate and the Participant. The distribution
of any Vested Units occurring by reason of this Section 1.7 shall be settled by

--------------------------------------------------------------------------------

EXHIBIT 10.2

the delivery of one share of Stock (subject to adjustment under the Plan) per
Vested Unit and shall occur as soon as practicable following certification by
the Administrator of the number of Earned PRSUs as of the date the Award becomes
vested pursuant to the terms of this Section 1.7, but in no event later than the
earlier of (A) 90 days following the date the Award becomes vested, or (B) March
15th of the year following the year in which the Award becomes vested. No
fractional Shares shall be issued pursuant to this Agreement.
1.8.
Non-Transferability of PRSUs. The PRSU acquired by the Participant pursuant to
this Agreement shall not be sold, transferred, pledged, assigned or otherwise
encumbered or disposed of except as provided below and in the Plan.

1.9.
Dividends, etc.. The Participant shall not be entitled: (i) to receive any
dividends or other distributions paid with respect to the Stock to which the
PRSU relates, or (ii) to vote any Stock with respect to which the PRSU relates.
Notwithstanding the foregoing, the number of Target PRSUs in the Award shall be
deemed increased to the extent that dividends are paid on the Stock during the
term of the Award and any dividend payments will be deemed reinvested on the
ex-dividend date in additional Stock and dividends on such additional Stock
shall be deemed reinvested in the same manner, with respect only to Earned
PRSUs.

1.10.
Sale of Vested Shares. The Participant understands that Participant will be free
to sell any Stock with respect to which the PRSU relates once the PRSU has
vested, subject to (i) satisfaction of any applicable tax withholding
requirements with respect to the vesting of such PRSU; (ii) the completion of
any administrative steps (for example, but without limitation, the transfer of
certificates) that the Company may reasonably impose; and (iii) applicable
requirements of federal and state securities laws.

1.11.
Certain Tax Matters. The Participant expressly acknowledges that the award or
vesting of the PRSU acquired hereunder, may give rise to "wages" subject to
withholding. The Participant expressly acknowledges and agrees that
Participant’s rights hereunder are subject to Participant promptly paying to the
Company all taxes required to be withheld in connection with such award, vesting
or payment. Until the Administrator determines otherwise, such payment of
Participant’s withholding tax obligations shall be made through net share
settlement procedures whereby that number of the vesting shares needed to cover
the withholding tax obligation (calculated using the Fair Market Value of the
Company’s stock on the date of vest) shall be cancelled to fund the Company’s
payment of the withholding tax obligation and the net shares remaining after
such cancellation shall be credited to Participant’s account. The value of any
Stock withheld for tax withholding may not exceed the amount allowed consistent
with fixed plan accounting in accordance with generally accepted accounting
practices in effect in the U.S., to the extent applicable.

EXHIBIT 10.2

in Sections 13(d) and 14(d)(2) of the 1934 Act) is or becomes the “beneficial
owner” (as defined in Rule 13d-3 under the 1934 Act), directly or indirectly, of

the Company; (b) during any period of two (2) consecutive years or less,
individuals who at the beginning of such period constituted the Board cease, for

corporation following the effective date of such merger or consolidation;
provided, however, that no Change in Control shall be deemed to have occurred

the Company or an Affiliate of any agreement with the Participant.
2.2.
No Understandings as to Employment etc. The Participant further expressly
acknowledges that nothing in the Plan or any modification thereto, in the Award
or in this Agreement shall constitute or be evidence of any understanding,
express or implied, on the part of the Company to employ or retain the
Participant for any period or with respect to the terms of the Participant’s
employment or to give rise to any right to remain in the service of the Company
or of any subsidiary or affiliate of the Company, and the Participant shall
remain subject to discharge to the same extent as if the Plan had never been
adopted or the Award had never been made.

2.3.
Compliance with Section 409A of the Code. Notwithstanding any other provision of
the Plan or this Agreement to the contrary, the Plan and this Agreement shall be
construed or deemed to be amended as necessary to remain exempt from or comply
with the requirements of Section 409A of the Code and to avoid the imposition of
any additional or accelerated taxes or other penalties under Section 409A of the
Code. The Committee, in its sole discretion, shall determine the requirements of
Section 409A of the Code applicable to the Plan and this Agreement and shall
interpret the terms of each consistently therewith. Under no circumstances,
however, shall the Company, an Affiliate, or a Subsidiary have any liability

also understands that the transfer of the information outlined herein is
important to the administration of the Award and the Plan and failure to consent
to the transmission of such information may limit or prohibit Participant’s
participation under the Plan and/or void the Award.
2.5.
Savings Clause. In the event that Participant is employed or provides services
in a jurisdiction where the performance of any term or provision of this
Agreement by the Company: (i) will result in a breach or violation of any
statute, law, ordinance, regulation, rule, judgment, decree, order or statement
of public policy of any court or governmental agency, board, bureau, body,
department or authority, or (ii) will result in the creation or imposition of
any penalty, charge, restriction, or material adverse effect upon the Company,

executed and delivered by the Participant and the Company or by the Company and
accepted by the Participant in accordance with the procedures specified in the
