issuance upon exercise of options granted under the Plan.  The
number and kind of shares reserved for issuance may be adjusted as
provided by ITEM FOURTEENTH.  Shares subject to an unexercised
installment of any canceled, surrendered or expired installment or
option may be again subject to option under the Plan.

     (a)  to determine and designate the recipients of options, the
          dates options are granted, the number of shares subject
          to option, option prices, option periods and option
          terms, except as limited by ITEM FOURTH, and

     (b)  to prescribe, amend and rescind rules and procedures for
          convenient administration of the Plan.

     Action by the Committee shall be authorized or ratified by a
majority of the Committee members and may be without notice or
meeting, by a writing signed by a majority of the Committee
members.

     In any dispute or disagreement as to the interpretation of the
Plan, or any rule or procedure of the Committee, or any question,
right or obligation under the Plan, the decision of the Board of
Directors shall be final and binding upon all persons.

THIRD:    Eligibility

     Key employees, including officers, of CTS shall be eligible to
receive options and shall receive options when, and if, designated
by the Committee.  Directors who are not also employees or officers
of CTS shall not be eligible to receive options.

FOURTH:   Option Grant

     The Committee shall determine and designate (i) the recipients
of options, (ii) the dates options are granted, (iii) the number of

FIFTH:    Option Price

     The option price shall be not less than the fair market value
of the shares on the date the option is granted.  Fair market value
of the shares shall be the reported closing price of the shares on
the New York Stock Exchange on the date the option is granted, or,
if not reported on such date, on the next preceding date for which
such a closing price is reported.

SIXTH:    Option Ceiling

     The aggregate fair market value (determined as of the time the
option is granted) of the shares of Common Stock for which any
participant may be granted incentive stock options which become
first exercisable in any calendar year, shall not exceed $100,000.

SEVENTH:  Option Grant Period

     The period during which an option may be granted, shall, in no
case, extend more than ten years after the Plan is adopted, or the
date such Plan is approved by the stockholders, whichever is
earlier.

EIGHTH:   Option Exercise Period

     The period during which an option may be exercised shall, in
no case, extend more than ten years after the date the option is
granted.

NINTH:    Option Terms

     The options shall be irrevocable and shall, on the date of
grant, conform in all respects with the Plan and may be non-
qualified or may conform with Section 422A of the Internal Revenue
Code of 1986, as amended, hereinafter the "Code," or with any law
supplemental thereto or substituted therefor.  Inconsistencies
between an option and the Plan shall be resolved according to the
terms of the Plan.

TENTH:    Exercise of Option

     The right to exercise an option shall accrue in such annual
and cumulative installments and at such times as designated by the
Committee, commencing at least one year from the date the option is
granted.  Unless otherwise designated by the Committee (i) the
number of installments shall be equal to the total number of years
of the option period minus one; (ii) each installment shall be
equal to the total number of shares under option divided by the
number of installments; and (iii) each installment cumulatively
shall permit the exercise of any previously unexercised
installment.

ELEVENTH: Payment

     Payment of the option price shall be made upon exercise of any
installment of an option, and the person exercising such option
shall supply the Committee such pertinent information as the
Committee may deem necessary.  Payment may be made in cash or in
previously acquired CTS Common Stock.  Except as provided in ITEM
THIRTEENTH, no option may be exercised unless, from the date the
option is granted to the date of exercise, the option holder is an
employee of CTS.  An option holder shall have no rights as a
stockholder with respect to shares subject to option until such
shares are issued.

TWELFTH:  Nontransferability of Option

     Options shall not be assignable or transferable by the option
holder other than by will or by the laws of descent and
distribution.

THIRTEENTH:    Effect of Termination of Employment or Change of
Control

     Upon the death of an option holder, all unexpired installments
of his options shall be accelerated and shall accrue  as of the
date of death, and his estate or the person or persons to whom his
rights under the option shall pass by will or by the laws of
descent and distribution may exercise the options, but only within
one year after his death or, if sooner, until the option period
expires.

     Upon total and permanent disability of an option holder,
within the meaning of Section 105(d)(4) of the Code, all unexpired
installments of his options shall be accelerated and shall accrue
as of the date of such disability, and he may exercise the options
but only within one year of the date of such disability or, if
sooner, until the option period expires.

     Upon retirement of an option holder, all unexpired
installments of his options shall be accelerated and shall accrue
as of the date of retirement, and he may exercise the options, but
only within three months after retirement or, if sooner, until the
option period expires.

     Upon termination of employment of the option holder with CTS
for any reason, other than death, disability, or retirement, he may
exercise his options only to the extent he is entitled by the
option terms on the date of termination, but such exercise may be
only within three months after termination or, if sooner, until the
option period expires.

     Upon a Change of Control of CTS Corporation, as defined in
Appendix A to this Plan, all unexpired installments of the option
holders' options shall immediately become exercisable in full, and
such options may be exercised within the three months immediately
following such date or, if sooner, until the option period expires.

FOURTEENTH:    Adjustment for Capital Change

     The number, kind and price of shares subject to option and the
number and kind of securities or property reserved for issuance,
and to be issued, upon exercise of options shall be proportionately
and appropriately adjusted by the Committee to reflect the effects
of stock splits, stock dividends and any other change in the
capital structure of CTS Corporation or to reflect any merger,
consolidation or exchange or sale of assets or shares of CTS
Corporation.

FIFTEENTH:     Amendment and Termination

     The Board of Directors may modify or amend the Plan without
stockholder approval at any time for the purpose of conforming to
changes in pertinent law or government regulations or for any
purpose permitted by law.  In no event, however, shall any such
action of the Board of Directors (i) increase, except as provided
by ITEM FOURTEENTH, the number of shares of Common Stock which may
be issued hereunder, (ii) decrease the option price, provided by
ITEM FIFTH, (iii) change the class of eligible employees, provided
by ITEM THIRD, (iv) change the option ceiling, provided by ITEM
SIXTH, or (v) impair any option granted prior to such action.

          members of the Board of the Company, or of any
          entity resulting from a Business Combination, at
          the time of such nomination.
