                  the Form 10-K filed with the Commission on February 14, 2003,
                  pursuant to the Exchange Act of 1934 (the "Exchange Act"),

pursuant to Sections 13(a), 13(c), 14 and 15(d) of the Securities Exchange Act
subsequent to the date of this Registration Statement and prior to the filing of

ITEM 4.  DESCRIPTION OF SECURITIES.

                  Not applicable.

ITEM 5.  INTERESTS OF NAMED EXPERTS AND COUNSEL.

                  Not applicable.

ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

                  The following summary of the material provisions of CTS'
bylaws relating to indemnification of directors and officers, CTS' articles of
incorporation, CTS' indemnification agreements with officers and directors and
the Indiana Business Corporation Law is not intended to be exclusive and is
qualified in its entirety by such bylaws, articles of incorporation,
indemnification agreements and statutes.

                  CTS' bylaws provide that CTS shall indemnify its officers and
directors to the fullest extent permitted by applicable law. Chapter 37 of the
Indiana Business Corporation law provides, in general, that each director and
officer of a corporation may be indemnified against liabilities (including


                                       2
<PAGE>
attorneys' fees), judgments, fines and amounts paid in settlement actually and
reasonably incurred in connection with the defense or settlement of any
threatened, pending or completed legal proceedings in which he or she is
involved by reason of the fact that he or she is or was a director or officer,
if he or she acted in good faith and in a manner that he or she reasonably
believed to be in or not opposed to the best interest of the corporation, and,
with respect to any criminal action or proceeding, if he or she had no
reasonable cause to believe that his or her conduct was unlawful. If the legal
proceeding, however, is by or in the right of the corporation, the director or
officer may not be indemnified in respect of any claim, issue or matter as to
which he or she has been adjudged to be liable for negligence or misconduct in
the performance of his or her duty to CTS unless a court determines otherwise.

                  CTS' articles of incorporation provide that the personal
liability of the directors of CTS will be eliminated to the fullest extent
permitted by applicable law. The bylaws provide that no director of CTS will be
personally liable to the corporation or its shareholders for monetary damages
for any breach of his fiduciary duty as a director provided, however, that such
provision does not apply to any liability of a director (a) for breach of
fiduciary duty if such breach constitutes willful misconduct or recklessness or
(b) for the payment of distributions to shareholders in violation of Section
23-1-28-3 of the Indiana Business Corporation Law.

                  Pursuant to separate indemnification agreements with CTS, each
officer and director of CTS is indemnified from all liabilities arising out of
the activities reasonably taken in the performance of their respective duties as
officers and directors of CTS.

                  CTS also maintains insurance for officers and directors
against certain liabilities, including liabilities under the Securities Act of
1933. The effect of this insurance is to indemnify any officer or director of
CTS against expenses, including, without limitation, attorneys' fees, judgments,
fines and amounts paid in settlement, incurred by an officer or director upon a
determination that such person acted in good faith. The premiums for such
insurance are paid by CTS.

24                         Power of Attorney

                  The Registrant undertakes that the CTS Corporation Retirement
Savings Plan and any amendments thereto have been or will be submitted to the
Internal Revenue Service (the "IRS") in a timely manner and all changes required
by the IRS in order to qualify such plans have been or will be made.

ITEM 9.  UNDERTAKINGS.

         (a)      The Registrant hereby undertakes:

                  (1) To file, during any period in which offers or sales are
being made, a post-effective amendment to this registration statement:

                           (i) to include any prospectus required by Section
         10(a)(3) of the Securities Act;

                           (ii) to reflect in the prospectus any facts or events
         arising after the effective date of this registration statement (or the
         most recent post-effective amendment thereof) which, individually or in
         the aggregate, represent a fundamental change in the information set
         forth in this registration statement. Notwithstanding the foregoing,
         any increase or decrease in the volume of securities offered (if the
         total dollar value of securities offered would not exceed that which
         was registered) and any deviation from the low or high end of the
         estimated maximum offering range may be reflected in the form of a
         prospectus filed with the Commission pursuant to Rule 424(b) if, in the
         aggregate, the changes in volume and price represent no more than a 20
         percent change in the maximum aggregate price set forth in the
         "Calculation of Registration Fee" table in the effective registration
         statement; and

                           (iii) to include any material information with
         respect to the plan of distribution not previously disclosed in this
         registration statement or any material change to such information in
         this registration statement;

                  provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do
not apply if the information required to be included in a post-effective
amendment by those paragraphs is contained in periodic reports filed by the
Registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are
incorporated by reference in this registration statement.

                  (2) That, for the purpose of determining any liability under
the Securities Act, each such post-effective amendment will be deemed to be a
new registration statement relating to the securities offered therein, and the
offering of such securities at that time will be deemed to be the initial bona
fide offering thereof.

                  (3) To remove from registration by means of a post-effective
amendment any of the securities being registered which remain unsold at the
termination of the offering.

         (b) The Registrant hereby undertakes that, for purposes of determining
any liability under the Securities Act, each filing of the Registrant's annual
report pursuant to Section 13(a) or Section 15(d) of the Exchange Act (and,
where applicable, each filing of an employee benefit plan's annual report
pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference
in this registration



                                       4
<PAGE>
statement will be deemed to be a new registration statement relating to the
securities offered therein, and the offering of such securities at that time
will be deemed to be the initial bona fide offering thereof.

         (c) Insofar as indemnification for liabilities arising under the
Securities Act may be permitted to directors, officers and controlling persons
of the Registrant pursuant to the foregoing provisions, or otherwise, the
Registrant has been advised that in the opinion of the Commission such
indemnification is against public policy as expressed in the Securities Act and
is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the Registrant of expenses
incurred or paid by a director, officer or controlling person of the Registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.

                  the Form 10-K filed with the Commission on February 14, 2003,

ITEM 4.  DESCRIPTION OF SECURITIES.

                  Not applicable.

ITEM 5.  INTERESTS OF NAMED EXPERTS AND COUNSEL.

                  Not applicable.

ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

                  The following summary of the material provisions of CTS'
bylaws relating to indemnification of directors and officers, CTS' articles of
incorporation, CTS' indemnification agreements with officers and directors and
the Indiana Business Corporation Law is not intended to be exclusive and is
qualified in its entirety by such bylaws, articles of incorporation,
indemnification agreements and statutes.

                  CTS' bylaws provide that CTS shall indemnify its officers and
directors to the fullest extent permitted by applicable law. Chapter 37 of the
Indiana Business Corporation law provides, in general, that each director and
officer of a corporation may be indemnified against liabilities (including

                                       2
attorneys' fees), judgments, fines and amounts paid in settlement actually and
reasonably incurred in connection with the defense or settlement of any
threatened, pending or completed legal proceedings in which he or she is
involved by reason of the fact that he or she is or was a director or officer,
if he or she acted in good faith and in a manner that he or she reasonably
believed to be in or not opposed to the best interest of the corporation, and,
with respect to any criminal action or proceeding, if he or she had no
reasonable cause to believe that his or her conduct was unlawful. If the legal
proceeding, however, is by or in the right of the corporation, the director or
officer may not be indemnified in respect of any claim, issue or matter as to
which he or she has been adjudged to be liable for negligence or misconduct in
the performance of his or her duty to CTS unless a court determines otherwise.

                  CTS' articles of incorporation provide that the personal
liability of the directors of CTS will be eliminated to the fullest extent
permitted by applicable law. The bylaws provide that no director of CTS will be
personally liable to the corporation or its shareholders for monetary damages
for any breach of his fiduciary duty as a director provided, however, that such
provision does not apply to any liability of a director (a) for breach of
fiduciary duty if such breach constitutes willful misconduct or recklessness or
(b) for the payment of distributions to shareholders in violation of Section
23-1-28-3 of the Indiana Business Corporation Law.

                  Pursuant to separate indemnification agreements with CTS, each
officer and director of CTS is indemnified from all liabilities arising out of
the activities reasonably taken in the performance of their respective duties as
officers and directors of CTS.

                  CTS also maintains insurance for officers and directors
against certain liabilities, including liabilities under the Securities Act of
1933. The effect of this insurance is to indemnify any officer or director of
CTS against expenses, including, without limitation, attorneys' fees, judgments,
fines and amounts paid in settlement, incurred by an officer or director upon a
determination that such person acted in good faith. The premiums for such
insurance are paid by CTS.

24                         Power of Attorney

                  The Registrant undertakes that the CTS Corporation Retirement
Savings Plan and any amendments thereto have been or will be submitted to the
Internal Revenue Service (the "IRS") in a timely manner and all changes required
by the IRS in order to qualify such plans have been or will be made.

ITEM 9.  UNDERTAKINGS.

         (a)      The Registrant hereby undertakes:

                  (1) To file, during any period in which offers or sales are
being made, a post-effective amendment to this registration statement:

                           (i) to include any prospectus required by Section
         10(a)(3) of the Securities Act;

                           (ii) to reflect in the prospectus any facts or events
         arising after the effective date of this registration statement (or the
         most recent post-effective amendment thereof) which, individually or in
         the aggregate, represent a fundamental change in the information set
         forth in this registration statement. Notwithstanding the foregoing,
         any increase or decrease in the volume of securities offered (if the
         total dollar value of securities offered would not exceed that which
         was registered) and any deviation from the low or high end of the
         estimated maximum offering range may be reflected in the form of a
         prospectus filed with the Commission pursuant to Rule 424(b) if, in the
         aggregate, the changes in volume and price represent no more than a 20
         percent change in the maximum aggregate price set forth in the
         "Calculation of Registration Fee" table in the effective registration
         statement; and

                           (iii) to include any material information with
         respect to the plan of distribution not previously disclosed in this
         registration statement or any material change to such information in
         this registration statement;

                  provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do
not apply if the information required to be included in a post-effective
amendment by those paragraphs is contained in periodic reports filed by the
Registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are
incorporated by reference in this registration statement.

                  (2) That, for the purpose of determining any liability under
the Securities Act, each such post-effective amendment will be deemed to be a
new registration statement relating to the securities offered therein, and the
offering of such securities at that time will be deemed to be the initial bona
fide offering thereof.

                  (3) To remove from registration by means of a post-effective
amendment any of the securities being registered which remain unsold at the
termination of the offering.

         (b) The Registrant hereby undertakes that, for purposes of determining
any liability under the Securities Act, each filing of the Registrant's annual
report pursuant to Section 13(a) or Section 15(d) of the Exchange Act (and,
where applicable, each filing of an employee benefit plan's annual report
pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference
in this registration

                                       4
statement will be deemed to be a new registration statement relating to the
securities offered therein, and the offering of such securities at that time
will be deemed to be the initial bona fide offering thereof.

         (c) Insofar as indemnification for liabilities arising under the
Securities Act may be permitted to directors, officers and controlling persons
of the Registrant pursuant to the foregoing provisions, or otherwise, the
Registrant has been advised that in the opinion of the Commission such
indemnification is against public policy as expressed in the Securities Act and
is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the Registrant of expenses
incurred or paid by a director, officer or controlling person of the Registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.
