future grant under the Plan. However, should the Company reacquire Shares which
were issued pursuant to the exercise of an Option, such Shares shall not become
available for future grant under the Plan.

        4. Administration of the Plan.

               (a) Initial Plan Procedure and Limitations. Prior to the date, if
any, of an Initial Public Offering or of a registered public offering of debt
securities by the Company, the Plan shall be administered by the compensation
committee of the Board, which Committee shall be composed solely of two or more
Outside Directors; provided, however, that such Committee shall not have the
discretionary authority to modify, amend or waive any provision of outstanding
Options.

               (b) Plan Procedure After the Date, if any, of the Initial Public
Offering or a Registered Public Offering of Debt Securities. After the date, if
any, of the Initial Public Offering or a registered public offering of debt
securities by the Company until the date upon which CVC's aggregate ownership of
the Company Common Stock becomes an amount less than ten percent of the Company
Common Stock, the Plan shall also be administered by the compensation committee
appointed by the Board; which Committee shall be composed solely of two or three
(but no more than three) Outside Directors, at least one of whom shall be a
designee of CVC; provided, however, that such Committee shall have the
discretionary authority to take any actions with respect to any outstanding
options only with at least a two-thirds vote of the Committee or, in the
alternative, upon a majority vote of the Committee ratified by approval of at
least two-thirds of the Board.

        After the date, if any, upon which CVC's aggregate ownership of the
Company Common Stock becomes an amount less than ten percent of the Company
Common Stock, the Plan shall also be administered by the compensation committee
appointed by the Board; which Committee shall be composed of two or more Outside
Directors, and which Committee shall have the full discretionary authority to
take all actions as described herein upon a majority vote of such Committee.

        Once appointed, such Committee shall continue to serve in its designated
capacity until otherwise directed by the Board. Subject to the requirement set
forth above that during a certain period at least one member of the Committee
shall be a designee of CVC, from time to time the Board may increase the size of
the Committee (but not to a size of more than three members so long as CVC owns
at least 10% of the Company Common Stock, and appoint additional members
thereof, remove members (with or without cause) and appoint new members in
substitution therefor, fill vacancies, however caused, all to the extent
permitted by Rule 16b-3 with respect to a plan intended to qualify thereunder as
a discretionary plan.

               (c) Powers of the Committee. Subject to (i) the provisions of the
Plan, (ii) the specific limitations on the Committee's exercise of discretion
set forth earlier in this Section, (iii) the

                                               -4-

   5

specific duties delegated by the Board to such Committee, and (iv) the approval
of any relevant authorities, including the approval, if required, of any stock
exchange upon which the Common Stock is listed, the Committee shall have the
authority, in its discretion:

                      (i) to determine the Fair Market Value of the Common
Stock, in accordance with Section 2(p) of the Plan;

                      (ii) to select the Consultants and Employees to whom
Options may from time to time be granted hereunder;

                      (iii) to determine whether and to what extent Options are
granted hereunder;

                      (iv) to determine the number of shares of Common Stock to
be covered by each such award granted hereunder;

                      (v) to approve forms of agreement for use under the Plan;
provided, however, that the forms of stock option agreement and exercise notice
used in successive stock option grants to Robert S. Cecil and the PI Parent
Corporation management team (the "Initial Optionees") shall be identical (except
as to number of shares and exercise price and as to any changes which would have
no adverse effect upon the Initial Optionees) to those forms of stock option
agreement and exercise notice used in the initial grants under this Plan to the
Initial Optionees;

                      (vi) to determine the terms and conditions, not
inconsistent with the terms of the Plan, of any award granted hereunder. Such
terms and conditions include, but are not limited to, the exercise price, the
time or times when Options may be exercised (which may be based on performance
criteria), any vesting acceleration, and any restriction or limitation regarding
any Option or the shares of Common Stock relating thereto, based in each case on
such factors as the Committee, in its sole discretion, shall determine;

                      (vii) to determine whether and under what circumstances an
Option may be settled in cash under subsection 9(d) instead of Common Stock;

                      (viii) to reduce the exercise price of any Option to the
then current Fair Market Value if the Fair Market Value of the Common Stock
covered by such Option shall have declined since the date the Option was
granted; and

                      (ix) to construe and interpret the terms of the Plan and
awards granted pursuant to the Plan.

               (d) Effect of Committee's Decision. All decisions, determinations
and interpretations of the Committee shall be final and binding on all Optionees
and any other holders of any Options.



                                       -5-

   6

        5.     Eligibility

               (a) Nonstatutory Stock Options may be granted to Employees and
Consultants. Incentive Stock Options may be granted only to Employees. An
Employee or Consultant who has been granted an Option may, if otherwise
eligible, be granted additional Options. Outside Directors are not eligible to
participate in the Plan.

               (b) Each Option shall be designated in the written option
agreement as either an Incentive Stock Option or a Nonstatutory Stock Option.
However, notwithstanding such designations, to the extent that the aggregate
Fair Market Value of the Shares with respect to which Options designated as
Incentive Stock Options are exercisable for the first time by any Optionee
during any calendar year (under all plans of the Company or any Parent or
Subsidiary) exceeds $100,000, such excess Options shall be treated as
Nonstatutory Stock Options.

               (c) For purposes of Section 5(b), Incentive Stock Options shall
be taken into account in the order in which they were granted, and the Fair
Market Value of the Shares shall be determined as of the time the Option with
respect to such Shares is granted.

               (d) The Plan shall not confer upon any Optionee any right with
respect to continuation of employment or consulting relationship with the
Company, nor shall it interfere in any way with his or her right or the
Company's right to terminate his or her employment or consulting relationship at
any time, with or without cause.

               (e) The following limitations shall apply to grants of Options:

                      (i) No Employee or Consultant shall be granted in any
fiscal year of the Company, Options to purchase more than 15,966 Shares; and

                      (ii) Over the term of the Plan, no Employee or Consultant
shall be granted Options to purchase more than 15,966 Shares.

        The foregoing limitations set forth in this Section 5(e) are intended to
satisfy the requirements applicable to Options intended to qualify as
"performance-based compensation" (within the meaning of Section 162(m) of the
Code) and are subject to an automatic proportionate increase in the event of an
increase to either the Shares issuable pursuant to the Plan or to the Shares
issuable pursuant to a particular Option under Sections 3 and 11 herein. In the
event the Committee determines that such limitations are not required to qualify
Options as performance-based compensation, the Committee may modify or eliminate
such limitations.

        6. Term of Plan. The Plan shall become effective upon the earlier to
occur of its adoption by the Board or its approval by the stockholders of the
Company as described in Section 17 of the Plan. It shall continue in effect for
a term of ten (10) years unless sooner terminated under Section 13 of the Plan.



                                       -6-

   7

        7. Term of Option. The term of each Option shall be the term stated in
the Option Agreement; provided, however, that the term shall be no more than ten
(10) years from the date of grant thereof. However, in the case of an Incentive
Stock Option granted to an Optionee who, at the time the Option is granted, owns
stock representing more than ten percent (10%) of the voting power of all
classes of stock of the Company or any Parent or Subsidiary, the term of the
Option shall be five (5) years from the date of grant thereof or such shorter
germ as may be provided in the Option Agreement.

        8.     Option Exercise Price and Consideration.

               (a) The per share exercise price for the Shares to be issued
pursuant to exercise of an Option shall be such price as is determined by the
Committee, but shall be subject to the following in the case of an Incentive
Stock Option:

                      (i) granted to an Employee who, at the time of the grant
of such Incentive Stock Option, owns stock representing more than ten percent
(10%) of the voting power of all classes of stock of the Company or any Parent
or Subsidiary, the per Share exercise price shall be no less than 110% of the
Fair Market Value per Share on the date of grant.

                      (ii) granted to any Employee, the per Share exercise price
shall be no less than 100% of the Fair Market Value per Share on the date of
grant.

               (b) In the case of a Nonstatutory Stock Option, the per Share
exercise price shall be determined by the Committee.

               (c) The consideration to be paid for the Shares to be issued upon
exercise of an Option, including the method of payment, shall be determined by
the Committee (and, in the case of an Incentive Stock Option, shall be
determined at the time of grant) and may consist entirely of (1) cash, (2)
check, (3) other Shares which (x) in the case of Shares acquired upon exercise
of an Option either have been owned by the Optionee for more than six months on
the date of surrender or were not acquired, directly or indirectly, from the
Company, and (y) have a Fair Market Value on the date of surrender equal to the
aggregate exercise price of the Shares as to which said Option shall be
exercised, (4) delivery of a properly executed exercise notice together with
such other documentation as the Committee and the broker, if applicable, shall
require to effect an exercise of the Option and delivery to the Company of the
sale or margin loan proceeds required to pay the exercise price, (5) any
combination of the foregoing methods of payment, or (6) such other consideration
and method of payment for the issuance of Shares to the extent permitted under
Applicable Laws.

        9. Exercise of option.

               (a) Procedure for Exercise; Rights as a Stockholder. Any Option
granted hereunder shall be exercisable at such times and under such conditions
as determined by the Committee, including performance criteria with respect to
the Company and/or the Optionee, and as shall be permissible under the terms of
the Plan.



                                       -7-

   8

                      An Option shall be deemed to be exercised when written
notice of such exercise has been given to the Company in accordance with the
terms of the Option by the person entitled to exercise the option and full
payment for the Shares with respect to which the Option is exercised has been
received by the Company. Full payment may, as authorized by the Committee,
consist of any consideration and method of payment allowable under Section 8(c)
of the Plan. Until the issuance (as evidenced by the appropriate entry on the
books of the Company or of a duly authorized transfer agent of the Company) of
the stock certificate evidencing such Shares, no right to vote or receive
dividends or any other rights as a stockholder shall exist with respect to the
Optioned Stock, notwithstanding the exercise of the Option. The Company shall
issue (or cause to be issued) such stock certificate promptly upon exercise of
the Option. No adjustment will be made for a dividend or other right for which
the record date is prior to the date the stock certificate is issued, except as
provided in Section 11 of the Plan.

                      Exercise of an Option in any manner shall result in a
decrease in the number of Shares which thereafter may be available, both for
purposes of the Plan and for sale under the Option, by the number of Shares as
to which the Option is exercised.

               (b) Termination of Employment or Consulting Relationship. This
entire paragraph being subject to the terms of an individual Optionee's
employment agreement with the Company and to the terms of option agreements with
respect to Options granted before April 23, 1996, upon termination of an
Optionee's Continuous Status as an Employee or Consultant, the Optionee may
exercise his or her Option within sixty (60) days from the date of termination.
If, on the date of termination, the Optionee is not entitled to exercise his or
her entire Option, the Shares covered by the unexercisable portion of the Option
shall revert to the Plan. If, after termination, the Optionee does not exercise
his or her Option within such sixty (60) day period, the Option shall terminate,
and the Shares covered by such Option shall revert to the Plan.

               (c) Rule l6b-3. Options granted to persons subject to Section
16(b) of the Exchange Act must comply with Rule 16b-3 and shall contain such
additional conditions or restrictions as may be required thereunder to qualify
for the maximum exemption from Section 16 of the Exchange Act with respect to
Plan transactions.

               (d) Buyout Provisions. The Committee may at any time offer to buy
out for a payment in cash or Shares, or may specify at the time of award the
circumstances under which an Optionee may sell for a payment in cash or Shares,
an Option previously granted, based on such terms and conditions as the
Committee shall establish and communicate to the Optionee at the time that such
offer or award is made.

               (e) Amendment of Registration Agreement and Stockholder
Agreement. In an effort to ensure that grantees of Options under the Plan are
able, upon the conversion of such Options into Common Stock, to participate in
those benefits and obligations of ownership of Common Stock offered to the other
holders thereof, the Company agrees promptly upon the adoption of the Plan to
take such action, and to use its best efforts to request its existing
stockholders to take such action, as may be necessary to:



                                       -8-

   9

                      (i) amend the definition of "Executive Stock Agreements"
        set forth in the Amended and Restated Registration Agreement dated as of
        December 29, 1989 by and among the Company and its stockholders, as
        amended (the "Registration Agreement") to include the Plan. The effect
        of such amendment will be to provide such holders acquiring Common Stock
        pursuant to the Plan with the demand registration rights and piggy-back
        registration rights set forth in Sections 1 and 2, respectively, of the
        Registration Agreement; and

                      (ii) amend the following provisions set forth in the
        Amended and Restated Stockholder Agreement dated as of December 29, 1989
        by and among the Company and its stockholders, as amended (the
        "Stockholder Agreement"):

                             (A) Section 2(a)(iii) of the Stockholder Agreement
        to provide that Robert S. Cecil shall have the right to nominate one
        person to the Board for so long as he is the chief executive officer of
        the Company;

                             (B) the definition of "Executive" set forth in the
        Stockholder Agreement to include all Optionees under the Plan. The
        effect of such amendment will be to provide such holders at any time
        after they purchase Shares hereunder with the limited purchase rights
        set forth in Section 7 of the Stockholder Agreement;

                             (C) Amend Section 6 of the Stockholder Agreement to
        include as "Participants" (as defined therein) the holders of Common
        Stock issued pursuant to the Plan. The effect of such amendment will be
        to provide such holders with the co-sale rights set forth in Section 6.

                             (D) Amend Section 8 of the Stockholder Agreement to
        provide that the approval of Robert S. Cecil will be required to consent
        to any "Freeze-Out" (as defined therein).

        10. Non-Transferability of Options. Except as otherwise determined by
the Committee, Options may not be sold, pledged, assigned, hypothecated,
transferred, or disposed of in any manner other than by will or by the laws of
descent or distribution and may be exercised, during the lifetime of the
Optionee, only by the Optionee.

        11.    Adjustments Upon Changes in Capitalization, Dissolution,
               Liquidation, Merger. Sale of Assets or Change of Control.

               (a) Changes in Capitalization. Subject to any required action by
the stockholders of the Company, in the event of a stock split, reverse stock
split, stock dividend, recapitalization, combination or reclassification of the
Company Common Stock, or any other increase or decrease in the number of issued
shares of Company Common Stock or in the number or amount of Convertible
Securities effected without receipt of consideration by the Company (provided,
however, that for purposes of this paragraph, conversion of any Convertible
Securities of the Company that are issued subsequent to the date of the adoption
of this Plan, including, without limitation, the conversion of



                                       -9-

   10

any such preferred stock of the Company into Common Stock, shall not be deemed
to have been "effected without receipt of consideration"), the number of shares
of Common Stock covered by each outstanding Option (including Options exercised
but as to which stock certificates have not been issued), and the number of
shares of Common Stock which have been authorized for issuance under the Plan
but as to which no Options have yet been granted or which have been returned to
the Plan upon cancellation or expiration of an Option, as well as the price per
share of Common Stock covered by each such outstanding Option, shall be
proportionately adjusted so that such Options' claim on assets, earnings and
voting power remains the same before and after any increase or decrease in the
number of issued shares of Common Stock resulting from such event. Such
adjustment shall be made by the Board, whose determination in that respect shall
be final, binding and conclusive. In the event that the Company undertakes any
corporate separation or division, including, without limitation, a split-up,
split-off or spin-off, the Committee shall provide that the holder of each
Option shall receive, upon a subsequent exercise of his or her Option, the same
per share consideration for each Share exercised that stockholders of the
Company received for each share of their holdings pursuant to the corporate
separation or division. In the event that the Company offers for sale any
Company Common Stock or any Convertible Securities for an initial consideration
price per share of Company Common Stock less than the Fair Market Value (as if
the defined term "Fair Market Value" in Section 2(p) herein applied to
Convertible Securities as well as to Company Common Stock) of such securities,
and in the further event that sales pursuant to such offerings result in the
Fair Market Value of the Common Stock declining, the per share exercise price of
each outstanding Option shall be adjusted so that the ratio of the exercise
price to the Fair Market Value of the Common Stock before and after the closing
of such sales remains constant. Such adjustment shall be made by the Board,
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 Committee shall notify the
Optionee at least thirty (30) days prior to such proposed action. To the extent
it has not been previously exercised, the Option will terminate immediately
prior to the consummation of such proposed action.

               (c) Merger, Sale of Assets or Change of Control. In the event of
a "Change of Control" (as defined below), the Committee shall provide for the
Optionee to have the right to exercise the Option as to all of the Optioned
Stock, including Shares as to which it would not otherwise be exercisable. In
such event, the Committee shall notify the Optionee that the Option shall be
exercisable for a period of not less than thirty (30) days from the date of such
notice. For these purposes, a "Change of Control" shall mean the occurrence of
any of the following events:

                      (i) Any "person" (as such term is used in Sections 13(d)
and 14(d) of the Securities Exchange Act of 1934, as amended) other than CVC and
each of its affiliates becomes the "beneficial owner" (as defined in Rule l3d-3
under said Act), directly or indirectly, of securities of the Company
representing forty percent (40%) or more of the total voting power represented
by the Company's then outstanding voting securities; or



                                      -10-
   11

                      (ii) A change in the composition of the Board occurring
within a two-year period, as a result of which fewer than a majority of the
directors are Incumbent Directors. "Incumbent Directors" shall mean directors
who (a) are directors of the Company as of the date this Plan is adopted, (b)
are elected, or nominated for election, to the Board with the affirmative votes
of at least a majority of the Incumbent Directors at the time of such election
or nomination (but shall not include an individual whose election or nomination
is in connection with an actual or threatened proxy contest relating to the
election of directors to the Company) or (c) are elected in accordance with the
terms of the Board Designation Agreement dated as of October 22, 1993, among CVC
and the Company; or

                      (iii) A merger or consolidation of the Company with any
other corporation, other than a merger or consolidation which would result in
the voting securities of the Company outstanding immediately prior thereto
continuing to represent (either by remaining outstanding or by being converted
into voting securities of the surviving entity) at least seventy percent (70%)
of the total voting power represented by the voting securities of the Company or
such surviving entity outstanding immediately after such merger or
consolidation, or the stockholders of the Company approve a plan of complete
liquidation of the Company or an agreement for the sale or disposition by the
Company of all or substantially of the Company's assets.

        For purposes of this paragraph 11(c), references to the "Company" shall
mean each of the Company, PI Holdings Inc., a Delaware corporation, and
Plantronics, Inc., a Delaware corporation.

        12. Time of Granting Options. The date of grant of an Option shall, for
all purposes, be the date on which the Committee makes the determination
granting such Option, or such other date as is determined by the Committee.
Notice of the determination shall be given to each Employee or Consultant to
whom an Option is so granted within a reasonable time after the date of such
grant.

        13. Amendment and Termination of the Plan.

               (a) Amendment and Termination. The Board may at any time amend,
alter, suspend or discontinue the Plan, but no amendment, alteration, suspension
or discontinuation shall be made which would impair the rights of any Optionee
under any grant theretofore made, without his or her consent. In addition, to
the extent necessary and desirable to comply with Rule 16b-3 under the Exchange
Act or with Section 422 of the Code (or any other applicable law or regulation,
including the requirements of the NASD or an established stock exchange), the
Company shall obtain stockholder approval of any Plan amendment in such a manner
and to such a degree as required.

               (b) Effect of Amendment or Termination. Any such amendment or
termination of the Plan shall not affect Options already granted and such
Options shall remain in full force and effect as if this Plan had not been
amended or terminated, unless mutually agreed otherwise between the Optionee and
the Company, which agreement must be in writing and signed by the Optionee and
the Company.

        14. Conditions Upon Issuance of Shares. Shares shall not be issued
pursuant to the 



                                      -11-
   12

exercise of an Option unless the exercise of such Option and the issuance and
delivery of such Shares pursuant thereto shall comply with all relevant
provisions of law, including, without limitation, the Securities Act of 1933, as
amended, the Exchange Act, 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.

               As a condition to the exercise of an Option, the Company may
require the person exercising such Option 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 relevant provisions of law.

        15. Reservation of Shares. The Company, during the term of this Plan,
will at all times reserve and keep available such number of Shares as shall be
sufficient to satisfy the requirements of the Plan.

        The inability of the Company to obtain authority from any regulatory
body having jurisdiction, which authority is deemed by the Company's counsel to
be necessary to the lawful issuance and sale of any Shares hereunder, shall
relieve the Company of any liability in respect of the failure to issue or sell
such Shares as to which such requisite authority shall not have been obtained;
provided, however, that the Company shall use its best efforts to obtain such
authority; provided, further, that if the Company fails to obtain such
authority, the Company shall pay to Optionees such amounts as to ensure that the
Optionees suffer no economic detriment by virtue of the failure to obtain such
authority.

        16. Agreements. Options shall be evidenced by written agreements in such
form as the Committee shall approve from time to time.

        17. Stockholder Approval. Continuance of the Plan shall be subject to
approval by the stockholders of the Company within twelve (12) months before or
after the date the Plan is adopted and within twelve (12) months before or after
the date of any increase in the number of shares available for issuance pursuant
to the Plan, to the extent required by Section 422 of the Code and the
regulations thereunder. Such stockholder approval shall be obtained in the
degree and manner required under applicable state and federal law and the rules
of any stock exchange upon which the Common Stock is listed.
