PLANTRONICS, INC.
2002 EMPLOYEE STOCK PURCHASE PLAN

Amended and Restated Effective as of May 19, 2016

1.    Purpose. The purpose of the Plan is to provide employees of the Company
and its Designated Subsidiaries with an opportunity to purchase Common Stock of
the Company through accumulated payroll deductions or a cash contribution, if
applicable. This Plan includes two components: a Code Section 423 Plan Component
and a Non-423 Plan Component. It is the intention of the Company to have the
Code Section 423 Plan Component qualify as an “Employee Stock Purchase Plan”
under Section 423 of the Code and the provisions of the Plan with respect to the
Code Section 423 Component, accordingly, shall be construed so as to extend and
limit participation in a manner consistent with the requirements of that section
of the Code. In addition, this Plan authorizes the grant of options under the
Non-423 Plan Component that do not qualify under Section 423 of the Code,
pursuant to the rules, procedures or sub-plans adopted by the Administrator that
are designed to achieve tax, securities laws or other objectives for Employees
and/or the Company. Except as otherwise indicated, the Non-423 Plan Component
will operate and be administered in the same manner as the Code Section 423 Plan
Component.

3.
Eligibility.

(a)    Subject to Section 3(b) below, any Employee who shall be employed by the
Company or a Designated Subsidiary for a minimum of seven (7) calendar days
prior to the first day of an Offering Period, or such other length of time
determined by the Administrator on or prior to that Offering Period shall be

participating in the Code Section 423 Plan Component, it will be applied in a
uniform and non-discriminatory basis.

(without regard to whether they also are citizens or residents of the United
States or resident aliens (within the meaning of Section 7701(b)(1)(A) of the
Code)) may be excluded from participation in the Plan or an Offering Period if
the participation of such Employees is prohibited under the laws of the
applicable jurisdiction or if complying with the laws of the applicable
jurisdiction would cause the Plan or an offering under the Plan to violate
Section 423 of the Code.
(c)    Any provisions of the Plan to the contrary notwithstanding, no Employee
shall be granted an option under the Plan;
(i)    to the extent that, immediately after the grant, such Employee (or any
other person whose stock would be attributed to such Employee pursuant to
Section 424(d) of the Code) would own capital stock of the Company and/or hold
outstanding options to purchase such stock possessing five percent (5%) or more
of the total combined voting power or value of all classes of the capital stock
of the Company or of any Subsidiary;
(ii)    to the extent that his or her rights to purchase stock under all
employee stock purchase plans (as defined in Section 423 of the Code) of the
Company and its Subsidiaries accrues at a rate which exceeds twenty-five
thousand dollars ($25,000) worth of Common Stock (determined at the Fair Market
Value of the shares at the time such option is granted) for each calendar year
in which such option is outstanding at any time; or
(iii)
to purchase more than 5,000 shares in any Offering Period.

4.    Offering Periods. The Plan shall be implemented by consecutive Offering
Periods with the Offering Period commencing on or around February 15 and August
15 of each year and ending approximately six (6) months later on August 15 and
February 15, respectively. If the commencement or ending date of any Offering
Period occurs on a weekend, holiday or other day on which any stock exchange or
national market system on which the Common Stock is listed is not open, the last
market trading date immediately prior shall be the applicable Offering Period
commencement or ending date. The Administrator shall have the power to change
the duration of Offering Periods (including the commencement dates thereof) with
respect to future offerings without stockholder approval if such change is
announced prior to the scheduled beginning of the first Offering Period to be
affected thereafter.
5.    Participation. An eligible Employee may become a Participant by submitting
a properly completed Subscription Agreement to the Company either through an
on-line enrollment process established by the Administrator or submitting a hard
copy to the Company’s stock administration manager on or prior to the applicable
Enrollment Date; provided that for purposes of Participants participating in the
Code Section 423 Plan Component, the processing of enrollments, whether on-line
or via hard copy, will be applied in a uniform and non-discriminatory basis.
6.
Payment Methods.

(a)    At the time a Participant submits his or her Subscription Agreement, he
or she shall elect to have payroll deductions made on each payday during the
Offering Period at a rate equal to not less than one percent (1.0%) and not
exceeding ten percent (10.0%) (in whole percentages only) of his or her
Compensation payable on each payday during the Offering Period.
(b)    Any such payroll deductions for a Participant shall commence on the first
payday following the first day of the Offering Period and shall end on the last
payday in the Offering Period to which such authorization is applicable, unless
sooner terminated by the Participant as provided in Section 10 hereof.

3

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

(c)    Notwithstanding the foregoing and lieu of the payroll deductions in
subsection (a) above, the Administrator may, for any Offering Period, permit
each Participant to make a lump sum cash contribution by check payable to the
Company in an amount equal to not less than one percent (1.0%) and not exceeding
ten percent (10.0%) (in whole percentages only) of his or her Compensation
payable during the Offering Period, subject to such conditions and limitations
as the Administrator may determine from time to time in its discretion; provided
that for purposes of Participants participating in the Code Section 423 Plan
Component, such conditions and limitations will be applied in a uniform and
non-discriminatory basis.
(d)    All payroll deductions or any cash contribution, if applicable, made by
or for a Participant shall be credited to his or her account under the Plan.
(e)    A Participant may discontinue his or her participation in the Plan as
provided in Section 10 hereof. A Participant’s Subscription Agreement shall
remain in effect for successive Offering Periods unless terminated as provided
in Section 10 hereof or modified by completion and timely submission of a new
Subscription Agreement prior to the applicable successive Offering Period
Enrollment Date.
(f)    Notwithstanding the foregoing, a Participant’s payroll deductions or cash
contribution, if applicable, may be decreased at any time to the extent
necessary to comply with Section 423(b)(8) of the Code and Section 3(c) hereof.
Any payroll deductions shall recommence at the rate provided in such
Participant’s Subscription Agreement at the beginning of the first Offering
Period which is scheduled to end in the following calendar year, unless the
Participant terminates the Subscription Agreement as provided in Section 10
hereof.
(g)    At the time the option is exercised, in whole or in part, or at the time
some or all of the Common Stock issued under the Plan is disposed of, the
Participant must make adequate provision for the Company’s federal, state, or
other tax withholding obligations, if any, which arise upon the exercise of the
option or the disposition of the Common Stock. At any time, the Company may, but
shall not be obligated to, withhold from the Participant’s pay the amount
necessary for the Company to meet applicable withholding obligations, including
any withholding required to make available to the Company any tax deductions or
benefits attributable to sale or early disposition of Common Stock by the
Participant.
7.    Grant of Option. On the first day of each Offering Period, each
Participant shall be granted an option to purchase on the Exercise Date of such
Offering Period (at the applicable Purchase Price) up to a number of shares of
Common Stock determined by dividing such Participant’s payroll deductions or
cash contribution, if applicable, accumulated prior to such Exercise Date and
retained in the Participant’s account as of the Exercise Date by the applicable
Purchase Price; provided that such purchase shall be subject to the limitations
set forth in Sections 3(c) and 12 hereof. Exercise of the option shall occur as
provided in Section 8 hereof, unless the Participant has previously withdrawn
pursuant to Section 10 hereof. The Administrator may, for future Offering
Periods, increase or decrease, in its absolute discretion, the maximum number of
shares of Common Stock a Participant may purchase during an Offering Period. The
option shall expire on the last day of the Offering Period.
8.    Exercise of Option. Unless a Participant previously withdraws from the
Plan as provided in Section 10 hereof, his or her option for the purchase of
shares shall be exercised automatically on the Exercise Date, and the maximum
number of shares subject to the option shall be purchased for such Participant
at the applicable Purchase Price with the accumulated payroll deductions or cash
contribution, if applicable, in his or her account. If the Exercise Date of any
Offering Period occurs on a weekend, holiday or other day on which any stock
exchange or national market system on which the Common Stock is listed is not
open, the applicable Offering Period Exercise Date shall be the last market
trading date immediately prior to the Exercise Date. Fractional shares may be
purchased subject to the limitations set forth in Section 3(c). Any payroll
deductions or cash contribution, if applicable, accumulated in a Participant’s
account which are in excess of the amounts permissible for the purchase of
shares authorized under Section 3(c), shall be returned to the Participant as
soon as administratively practicable after the Exercise Date of the relevant
Offering Period. During a Participant’s lifetime, a Participant’s option to
purchase shares hereunder is exercisable only by him or her.
9.    Delivery. As promptly as practicable after each Exercise Date, the Company
shall cause to be delivered to each Participant, as appropriate, the shares
purchased upon exercise of his or her option.

4

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

10.
Withdrawal.

(a)    A Participant may withdraw the entire balance credited to his or her
account and not yet used to exercise his or her option under the Plan at any
time through an on-line process established by the Administrator or by giving
written notice to the Company in a form(s) approved by the Administrator from
time to time at least two (2) business days prior to the applicable Exercise
Date. Notwithstanding the foregoing, for purposes of Participants participating
in the Code Section 423 Plan Component, the processing of withdrawals, whether
on-line or via hard copy, will be applied in a uniform and non-discriminatory
basis. The entire balance credited to a Participant’s account shall be paid to
such Participant promptly after timely receipt of the Participant’s notice of
withdrawal pursuant to this subsection, in which case such Participant’s option
for the Offering Period shall be automatically terminated, and no further
payroll deductions or cash contribution, if applicable, for the purchase of
shares shall be made for such Offering Period. If a Participant withdraws from
an Offering Period (or submits a withdrawal request pursuant to this subsection
that is not timely received for a particular Offering Period), his or her
participation in the Plan shall not resume at the beginning of the succeeding
Offering Period unless the Participant re-enrolls in the Plan by timely
submitting to the Company a new Subscription Agreement.
(b)    A Participant’s withdrawal from an Offering Period shall not have any
effect upon his or her eligibility to participate in any similar plan which may
hereafter be adopted by the Company or in succeeding Offering Periods which
commence after the termination of the Offering Period from which the Participant
withdraws.
11.    Termination of Employment. Upon a Participant’s ceasing to be an Employee
for any reason, he or she shall be deemed to have automatically and immediately
elected to withdraw from the Plan and the entire balance then credited to such
Participant’s account shall be returned to such Participant or, in the case of
his or her death, to the person or persons entitled thereto under Section 15
hereof, and such Participant’s option shall be automatically terminated. The
foregoing shall apply whether or not a Participant ceases to be an Employee
within the two (2) business days prior to an applicable Exercise Date referred
to in Section 10(a) above.
12.    Interest. No interest shall accrue on any amounts credited to a
Participant’s account under the Plan, except as may be required by Applicable
Laws, as determined by the Administrator, for Participants in the Non-423 Plan
Component (or the Code Section 423 Plan Component if permitted under Section 423
of the Code).
13.
Stock.

(a)    Subject to adjustment upon changes in capitalization of the Company as
provided in Section 19 hereof, the maximum number of shares of the Common Stock
available for sale under the Plan shall be 3,000,000 shares. If, on a given
Exercise Date, the number of shares with respect to which options for all
Participants are to be exercised exceeds the number of shares then available
under the Plan, the Company shall make a pro rata allocation of the shares
remaining available for purchase in as uniform a manner as shall be practicable
and as it shall determine to be equitable; provided, however, for purposes of
Participants participating in the Code Section 423 Plan Component, any pro rata
allocation, will be applied in a uniform and non-discriminatory basis.
(b)    The Participant shall have no interest, voting right or rights to
dividends in connection with shares covered by his or her option until such
option has been exercised.
(c)    Shares to be delivered to a Participant under the Plan shall be
registered in the name of the Participant.

5

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

14.    Administration. The Plan shall be administered by the Administrator. The
Administrator shall have full and exclusive discretionary authority to construe,
interpret and apply the terms of the Plan, to determine eligibility, to
adjudicate all disputed claims filed under the Plan and to establish such
procedures that it deems necessary for the administration of the Plan
(including, without limitation, to adopt such procedures and sub-plans as are
necessary or appropriate to permit the participation in the Plan by Employees
who are foreign nationals or employed outside the U.S., the terms of which
sub-plans may take precedence over other provisions of this Plan, with the
exception of Section 13(a) hereof, but unless otherwise superseded by the terms
of such sub-plan, the provisions of this Plan shall govern the operation of such
sub-plan). Unless otherwise determined by the Administrator, the Employees
eligible to participate in each sub-plan will participate in a separate
offering. Without limiting the generality of the foregoing, the Administrator is
specifically authorized to adopt rules and procedures regarding eligibility to
participate, the definition of Compensation, making of payroll deductions and/or
cash contributions under the Plan, handling of payroll deductions and/or cash
contributions, establishment of any bank or trust accounts to hold payroll
amounts deducted and/or cash contributions, any payment of interest, conversion
of local currency, obligations to pay payroll tax, determination of beneficiary
designation requirements, withholding procedures and handling of stock
certificates that vary with applicable local requirements. The Administrator
also is authorized to determine that, to the extent permitted by U.S. Treasury
Regulation Section 1.423‑2(f), the terms of an option granted under the Plan or
an Offering Period to citizens or residents of a non-U.S. jurisdiction will be
less favorable than the terms of options granted under the Plan or the same
Offering Period to Employees resident solely in the U.S. Every finding, decision
and determination made by the Administrator shall, to the full extent permitted
by law, be final and binding upon all parties, and shall be given the maximum
possible deference permitted by Applicable Laws.
15.
Designation of Beneficiary.

(a)    A Participant may file a written designation of a beneficiary who is to
receive any shares and cash, if any, from the Participant’s account under the
Plan in the event of such Participant’s death subsequent to an Exercise Date on
which the option is exercised but prior to delivery to such Participant of such
shares and cash. In addition, a Participant may file a written designation of a
beneficiary who is to receive any cash from the Participant’s account under the
Plan in the event of such Participant’s death prior to exercise of an option. If
a Participant is married and the designated beneficiary is not the spouse,
spousal consent shall be required for such designation to be effective.
(b)    Such designation of beneficiary may be changed by the Participant at any
time by written notice. In the event of the death of a Participant and in the
absence of a beneficiary validly designated under the Plan who is living at the
time of such Participant’s death, the Company shall deliver such shares and/or
cash to the executor or administrator of the estate of the Participant, or if to
the knowledge of the Company no such executor or administrator has been
appointed, the Company, in its discretion, may retain the shares and/or cash
until such time as a representative of the Participant’s estate is so appointed
or provides to the Administrator an order or instructions from a court or
administrative body of competent jurisdiction authorizing the release of such
shares and/or cash to the representative. The Administrator may, prior to the
release of any shares and/or cash, require execution of an indemnification or
other form of agreement relieving the Company, Administrator and all Company
agents and representatives from liability for invalid release of any shares
and/or cash.
(c)    Any beneficiary designations made pursuant to this Section shall be made
in the form and manner determined by the Administrator from time to time in its
discretion.
16.    Transferability. Neither payroll deductions or any cash contribution, if
applicable, credited to a Participant’s account nor any rights with regard to
the exercise of an option or to receive shares under the Plan may be assigned,
transferred, pledged or otherwise disposed of in any way (other than by will,
the laws of descent and distribution or as provided in Section 15 hereof) by the
Participant. Any such attempt at assignment, transfer, pledge or other
disposition shall be without effect, except that the Company may treat such act
as an election to withdraw funds from an Offering Period in accordance with
Section 10 hereof.
17.    Use of Funds. All payroll deductions and/or cash contributions received
or held by the Company under the Plan may be used by the Company for any
corporate purpose, and the Company shall not be obligated to segregate such
amounts unless otherwise required by Applicable Laws, as determined by the
Administrator.
18.    Reports. Individual accounts shall be maintained for each Participant.
Statements of account shall be given to Participants at least annually, which
statements shall set forth the amounts of payroll deductions and/or cash
contributions, if applicable, made by or for the Participant, the Purchase
Price, the number of shares of Common Stock purchased and the remaining cash
balance, if any.

6

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

19.
Adjustments Upon Changes in Capitalization, Dissolution, Liquidation, Merger or
Asset Sale.

(a)    Changes in Capitalization. Subject to any required action by the
stockholders of the Company, the Reserves, the maximum number of shares each
Participant may purchase per Offering Period (pursuant to Section 7), as well as
the price per share and the number of shares of Common Stock covered by each
option under the Plan which has not yet been exercised shall be proportionately
adjusted for any increase or decrease in the number of issued shares of Common
Stock resulting from a stock split, reverse stock split, stock dividend,
combination or reclassification of the Common Stock, or any other increase or
decrease in the number of shares of Common Stock effected without receipt of
consideration by the Company; provided, however, that conversion of any
convertible securities of the Company shall not be deemed to have been “effected
without receipt of consideration.” Such adjustment shall be made by the
Administrator, whose determination in that respect shall be final, binding and
conclusive. Except as expressly provided herein, no issuance by the Company of
shares of stock of any class, or securities convertible into shares of stock of
any class, shall affect, and no adjustment by reason thereof shall be made with
respect to, the number or price of shares of Common Stock subject to an option.
(b)    Dissolution or Liquidation. In the event of the proposed dissolution or
liquidation of the Company, the Offering Period then in progress shall be
shortened by setting a new Exercise Date (the “New Exercise Date”), and shall
terminate immediately prior to the consummation of such proposed dissolution or
liquidation, unless provided otherwise by the Administrator. The New Exercise
Date shall be before the date of the Company’s proposed dissolution or
liquidation. The Administrator shall notify each Participant in writing, at
least ten (10) business days prior to the New Exercise Date, that the Exercise
Date for the Participant’s option has been changed to the New Exercise Date and
that the Participant’s option shall be exercised automatically on the New
Exercise Date, unless prior to such date the Participant has withdrawn from the
Offering Period as provided in Section 10 hereof.
(c)    Merger or Asset Sale. In the event of a proposed sale of all or
substantially all of the assets of the Company, or the merger of the Company
with or into another corporation, each outstanding option shall be assumed or an
equivalent option substituted by the successor corporation or a parent or
subsidiary of the successor corporation. In the event that the successor
corporation refuses to assume or substitute for the option, the Offering Period
then in progress shall be shortened by setting a new Exercise Date (the “New
Exercise Date”). The New Exercise Date shall be before the date of the Company’s
proposed sale or merger. The Administrator shall notify each Participant in
writing, at least ten (10) business days prior to the New Exercise Date, that
the Exercise Date for the Participant’s option has been changed to the New
Exercise Date and that the Participant’s option shall be exercised automatically
on the New Exercise Date, unless prior to such date the Participant has
withdrawn from the Offering Period as provided in Section 10 hereof.
20.
Amendment or Termination.

(a)    The Administrator, in its sole discretion, may amend, suspend, or
terminate the Plan, or any part thereof, at any time and for any reason. Except
as provided in Section 19 hereof, no such termination can affect options
previously granted, provided that an Offering Period may be terminated by the
Administrator on any Exercise Date if the Administrator determines that the
termination of the Offering Period or the Plan is in the best interests of the
Company and its stockholders. Except as provided in Sections 19 and 20 hereof,
no amendment may make any change in any option theretofore granted which
adversely affects the rights of any Participant.
(b)    Without stockholder consent and without regard to whether any
Participant’s rights may be considered to have been “adversely affected,” the
Administrator shall be entitled to change the Offering Periods, limit the
frequency and/or number of changes in the amount withheld or contributed, if
applicable, during an Offering Period, establish the exchange ratio applicable
to amounts withheld or contributed, if applicable, in a currency other than U.S.
dollars, permit payroll withholding and/or contributions, if applicable, in
excess of the amount designated by a Participant in order to adjust for delays
or mistakes in the Company’s processing of properly completed withholding or
contribution elections, establish reasonable waiting and adjustment periods
and/or accounting and crediting procedures to ensure that amounts applied toward
the purchase of Common Stock for each Participant properly correspond with a
Participant’s payroll deductions or cash contribution, if applicable, and
establish such other limitations or procedures as the Administrator determines
in its sole discretion advisable which are consistent with the Plan.
(c)    In the event the Administrator determines that the ongoing operation of
the Plan may result in unfavorable financial accounting consequences, the
Administrator may, in its discretion and, to the extent necessary or desirable,
modify or amend the Plan to reduce or eliminate such accounting consequence
including, but not limited to:
(i)    altering the Purchase Price for any Offering Period including an Offering
Period underway at the time of the change in Purchase Price;
(ii)    shortening any Offering Period so that the Offering Period ends on a new
Exercise Date, including an Offering Period underway at the time of the
Administrator action; and
(iii)    allocating shares.
(d)    Such modifications or amendments shall not require stockholder approval
or the consent of any Participants.

7

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

21.    Notices. All notices or other communications by a Participant to the
Company under or in connection with the Plan shall be deemed to have been duly
given when received in the form specified by the Company at the location, or by
the person, designated by the Company for the receipt thereof.
22.
Conditions Upon Issuance of Shares.

(a)    Shares shall not be issued with respect to an option unless the exercise
of such option and the issuance and delivery of such shares pursuant thereto
shall comply with all applicable provisions of law, domestic or foreign,
including, without limitation, the Securities Act of 1933, as amended, the
Securities Exchange Act of 1934, as amended, the rules and regulations
promulgated thereunder, and the requirements of any stock exchange upon which
the shares may then be listed, and shall be further subject to the approval of
counsel for the Company with respect to such compliance.
(b)    As a condition to the exercise of an option, the Company may require a
Participant to represent and warrant at the time of any such exercise that the
shares are being purchased only for investment and without any present intention
to sell or distribute such shares if, in the opinion of counsel for the Company,
such a representation is required by any of the aforementioned applicable
provisions of law.
23.    Code Section 409A. The Code Section 423 Plan Component is exempt from the
application of Code Section 409A. The Non-423 Plan Component is intended to be
exempt from Code Section 409A under the short-term deferral exception and any
ambiguities herein will be interpreted to so be exempt from Code Section 409A.
In furtherance of the foregoing and notwithstanding any provision in the Plan to
the contrary, if the Administrator determines that an option granted under the
Plan may be subject to Code Section 409A or that any provision in the Plan would
cause an option under the Plan to be subject to Code Section 409A, the
Administrator may amend the terms of the Plan and/or of an outstanding option
granted under the Plan, or take such other action the Administrator determines
is necessary or appropriate, in each case, without the Participant’s consent, to
exempt any outstanding option or future option that may be granted under the
Plan from or to allow any such options to comply with Code Section 409A, but
only to the extent any such amendments or action by the Administrator would not
violate Code Section 409A. Notwithstanding the foregoing, the Company shall have
no liability to a Participant or any other party if the option to purchase
Common Stock under the Plan that is intended to be exempt from or compliant with
Code Section 409A is not so exempt or compliant or for any action taken by the
Administrator with respect thereto. The Company makes no representation that the
option to purchase Common Stock under the Plan is compliant with Code Section
409A.
24.    Term of Plan. The Plan shall become effective upon its adoption by the
Administrator or its approval by the stockholders of the Company, if applicable,
and shall continue in effect until terminated under Section 20 hereof.
25.    Stockholder Approval. The Plan will be subject to approval by the
stockholders of the Company in the manner and to the degree required under
Applicable Laws.
26.    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 California, United States and
construed accordingly, to the extent not superseded by applicable U.S. 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
unenforceability shall not affect any other provision of the Plan or part
thereof, each of which shall remain in full force and effect.
