bookkeeping account on the Employers records to record each Participants
potential interest in, and the activity of, the Retention Bonus Pool. The

the Committee and shall automatically revoke all prior designations by that
Participant. 10.2 Death of Beneficiary. In the event that all the Beneficiaries named
by a Participant pursuant to Section 10.1 predecease the Participant, then, on
the Participants death, any amounts due such Participant shall be paid to the

otherwise to the estate of the Participant. 10.3 Ineffective Designation. In the event a Participant does not

Retention Incentive Plan Addendum A Confidentiality/Non-Competition/Non-Solicitation Agreement As consideration for participation in the Knowles Electronics Holdings,
Inc. Retention Incentive Plan, the undersigned Employee agrees as follows: 1. Confidentiality and Ownership. (a) Information. The Employee acknowledges and agrees that the
proprietary information and data obtained by him while employed by the
Corporation or any of its Affiliates concerning the business or affairs
of the Corporation or any Affiliate (Confidential Information) are the
property of the Corporation or such Affiliate. Consequently, the Employee
agrees that, except to the extent required by applicable law, statute,
ordinance, rule, regulation or orders of courts or regulatory
authorities, he shall not disclose to any unauthorized person (which
shall not include customers or suppliers to whom information is provided
in the ordinary course in the interests of promoting their business
relationships with the Corporation or any of its Affiliates) or use for
his own account any Confidential Information without the prior written
consent of the Board, unless and to the extent that the aforementioned
matters become generally known to and available for use by the public
other than as a result of the Employees acts or omissions to act. The
Employee shall deliver to the Corporation at the termination of the
Employees employment, or at any other time the Corporation may request,
all memoranda, notes, plans, records, reports, computer tapes and
software and other documents and data (and copies thereof) relating to
the Confidential Information, Work Product (as defined below) and the
business of the Corporation or any Affiliate which he may then possess or
have under his control. (b) Inventions and Patents. The Employee agrees that all
inventions, innovations, improvements, developments, methods, designs,
analyses, drawings, reports, and all similar or related information which
relates to the Corporations or any of its Affiliates actual or
anticipated business, research and development or existing or future
products or services and which are conceived, developed or made by the
Employee prior to the date hereof while employed by the Corporation or
any of its Affiliates (Work Product) belong to the Corporation or such
Affiliate. The Employee will promptly disclose such Work Product to the
Board and perform all actions reasonably requested by the Board (whether
during or after the Employees employment period) to establish and
confirm such ownership (including, without limitation, assignments,
consents, powers of attorney and other instruments). 2. Non-compete, Non-solicitation. -10-

##### 



(a) Non-Compete. The Employee acknowledges that in the course of
his employment with the Corporation and its Affiliates he has become
familiar, and he will become familiar, with the Corporations and its
Affiliates trade secrets and with other Confidential Information and
that his services have been and will be of special, unique and
extraordinary value to the Corporation and its Affiliates. Therefore,
the Employee agrees that he shall not, during the time he is employed by
the Corporation and its Affiliates and for    months thereafter,
directly or indirectly own, operate, manage, control, participate in,
consult with, advise, engage in services for any competitor of the
Corporation or in any manner engage in any start up of a business
(including by himself or in association with any person, firm, corporate
or other business organization or through any other entity) in
competition with the businesses of the Corporation or its Affiliates as
in existence or in process on the date of termination of the Employees
employment (the Businesses), within any state or country in which the
Corporation or any of its Affiliates makes sales. Nothing herein shall
prohibit the Employee from being a passive owner of not more than 2% of
the outstanding stock or equity of an entity which is publicly traded, so
long as the Employee has no active participation in the business of such
entity. (b) Non-Solicitation. During the time the Employee is employed by
the Corporation and its Affiliates and for    months thereafter, the
Employee shall not directly or indirectly through another entity (i)
induce or attempt to induce any employee of the Corporation or any
Affiliate to leave the employ of the Corporation or such Affiliate, or in
any way interfere with the relationship between the Corporation or any
Affiliate and any employee thereof, including without limitation,
inducing or attempting to induce any union, employee or group of
employees to interfere with the business or operations of the Corporation
or its Affiliates, (ii) hire any person who was an employee of the
Corporation or any Affiliate at any time within the six month period
prior to the date the Employee employs or seeks to employ such person, or
(iii) induce or attempt to induce any supplier, distributor, franchisee,
licensee or other business relation of the Corporation or any Affiliate
to cease doing business with the Corporation or such Affiliate, or in any
way interfere with the relationship between any such customer, supplier,
distributor, franchisee, licensee or business relation and the
Corporation or any Affiliate. 3. In the event that the Employees employment is terminated by the
Corporation or an Affiliate for a reason described in Section 5.2 of the Plan,
any salary continuation or extension of coverage under the Corporation or
Affiliates medical plans otherwise due the Employee shall cease in the event
the Employee breaches any provisions of this Addendum A. 4. The Employee agrees that: (i) the covenants set forth in this Addendum
A are reasonable in geographical and temporal scope and in all other respects,
(ii) the Corporation and its Affiliates would not have allowed the Employee to
participate in the Plan, but for the covenants of the Employee contained
herein, and (iii) the covenants -11-




---



##### 



contained herein have been made in order to induce the Corporation and its
affiliates to allow the Employee to participate in the Plan. 5. If, at the time of enforcement of this Addendum A, a court shall hold
that the duration, scope or area restrictions stated herein are unreasonable
under circumstances then existing, the parties agree that the maximum duration,
scope or area reasonable under such circumstances shall be substituted for the
stated duration, scope or area and that the court shall be allowed to revise
the restrictions contained herein to cover the maximum period, scope and area
permitted by law. 6. The Employee recognizes and affirms that in the event of his breach of
any provision of this Addendum A, money damages would be inadequate and the
Corporation and its Affiliates would have no adequate remedy at law.
Accordingly, the Employee agrees that, in the event of a breach or a threatened
breach by the Employee of any of the provisions of this Addendum A, the
Corporation and its Affiliates, in addition and supplementary to other rights
and remedies existing in its favor, may apply to any court of law or equity or
competent jurisdiction for specific performance and/or injunctive or other
relief in order to enforce or prevent any violation so the provisions hereof
(without posting a bond or other security). Signed:___________________________________________________________
