                               AMENDMENT NO. 4 TO

                   AMENDED AND RESTATED REGISTRATION AGREEMENT

        This Amendment No. 4 to Amended and Restated Registration Agreement (the
"4th Amendment")is entered into effective as of May 18, 2000, by and among
Plantronics, Inc., a Delaware corporation (the "Company") and Citicorp Venture
Capital, Ltd., a new York corporation ("CVC"), Trude C. Taylor ("Taylor"), and
David A. Wegmann ("Wegmann") (collectively referred to as the "Stockholders").

                                    RECITALS

    A.     The Stockholders and the Company are parties to an Amended and
           Restated Registration Agreement, dated as of December 29, 1989 (the
           "Registration Agreement") (all capitalized terms not otherwise
           defined in this 4th Amendment shall have the meanings set forth in
           the Registration Agreement).

    B.     The Company is successor in interest to PI Parent Corporation, a
           party to the Registration Agreement, as amended.

    C.     The Stockholders, the Company and certain former stockholders of the
           Company entered into that certain Amendment No. 3 to the Registration
           Agreement, dated as of October 21, 1993 (the 3rd Amendment"),
           pursuant to which, subject to all other terms and conditions of the
           Registration Agreement, registration rights under the Registration
           Agreement were granted to officers or key employees of the Company
           upon exercise of options granted to such officers or key employees
           under the Company's 1993 Stock Plan (such officer or key employee
           option holders hereafter referred to as "Option Holders").

    D.     The parties to this Amendment desire to enter into this 4th Amendment
           in order to amend the Registration Agreement to cancel the inclusion
           of the Option Holders as parties to the Registration Agreement as of
           the effective date of this 4th Amendment.

    E.     The Stockholders entering into this 4th Amendment hold more than a
           majority of the Registrable Securities as that term is defined in the
           Registration Agreement.

                                    AGREEMENT

        NOW, THEREFORE, in consideration of the foregoing and for other good and
sufficient consideration, the receipt and sufficiency of which is hereby
acknowledged, the parties to this 4th Amendment agree as follows:

        1. TERMINATION OF REGISTRATION RIGHTS OF OPTION HOLDERS. Effective as of
May 18, 2000, the terms and provisions of the 3rd Amendment are hereby canceled

shares of common stock acquired by exercise of any option granted under the 1993
Stock Plan as Registrable Securities under the Registration Agreement.

        2. EFFECT OF 4TH AMENDMENT. This 4th Amendment supplements and amends
the Registration Agreement, as the same is previously amended. Where the
provisions of this 4th Amendment are in conflict with the Registration
Agreement, as amended, the provisions of this 4th Amendment shall control.
Except as expressly amended by this 4th Amendment, all other terms and
provisions of the Registration Agreement remain in full force and effect.

        IN WITNESS WHEREOF, the parties hereto have executed this Amendment No.
