Exhibit 99.1

PREFORMED LINE PRODUCTS COMPANY
DEFERRED SHARES PLAN
(Effective August 21, 2008)
SUMMARY

The following is a summary of certain provisions of the Plan. This summary is subject to, and qualified in its entirety by, the complete text of the Plan below.

A.
This Plan is intended to allow elective deferrals by Key Employees and Directors in the form of Deferred Shares from awards of Restricted Stock under the Preformed Line Products Company Long Term Incentive Plan of 2008 (the “Incentive Plan”) on behalf of Participants for future payment to Participants or their Beneficiaries (see Section 1.1).

B.
Only Key Employees and Directors who receive an award of Restricted Stock will be eligible to become Participants, and the Employer will notify each Key Employee and each Director who receives an award of Restricted Stock of his or her eligibility to participate (see Section 3.1).

C.
Each Key Employee and Director will agree to participate for a particular award of Restricted Stock by completing, signing, and delivering to the Employer a Deferred Share Agreement at the time of the execution of the respective Restricted Stock Award Agreement, which shall include an election as to Entitlement Date (see Section 3.1). Any elections may be changed only as provided in this Plan (see Section 3.2).

D.
Deferred Shares will be contributed to the Plan at the time of vesting, and each Participant’s right to distribution of any Deferred Shares contributed by that Participant will be fully vested (see Section 3.3). All Restricted Stock will vest in accordance with the respective Restricted Stock Award Agreement.

E.
The Participant’s Deferred Shares will be distributed on the Participant’s elected Entitlement Date. However, in the event that the Participant is a “Specified Employee” under section 409A of the Code and the Participant’s elected Entitlement Date is based upon the Participant experiencing a Separation from Service with the Employer, distribution of that Participant’s Deferred Shares will be delayed until the date that is six months after such Separation from Service (See Section 4.1).

F.
Although the intent of this Plan is that a Participant will not be subject to federal or Ohio income taxation with respect to any Deferred Shares until they are distributed, it is anticipated that each Participant will be subject to Social Security and Medicare taxation and may be subject to local income taxation for the Deferred Shares in the year of deferral.

2.2 CONSTRUCTION. Captions and titles contained herein are for convenience only and shall not affect the meaning or interpretation of any provision of this Plan. Terms defined in the singular shall include the plural, and vice versa, and pronouns in any gender shall include the masculine, feminine, and neuter, as the context requires. Any reference to any federal, state, local, or foreign statute or law shall be deemed also to refer to all rules and regulations promulgated thereunder, unless the context requires otherwise. The word “including” means including, without limitation, and use of the term “or” is not intended to be exclusive, unless the context clearly requires otherwise. All references to a “Section” refer to this Plan, unless the context otherwise requires.

SECTION 3.
ELIGIBILITY, PARTICIPATION AND VESTING

3.1 ELIGIBILITY AND PARTICIPATION. Each Key Employee or Director who receives an award of Restricted Stock will be eligible to become a Participant. Such Key Employee or Director will become a Participant by completing a Deferred Share Agreement (including Entitlement Date) in connection with an award of Restricted Stock under the Incentive Plan.

3.2 CHANGE IN DEFERRED SHARE AGREEMENT.

(a)
Except as otherwise provided in Section 3.2(b), after the execution and submission of the Deferred Share Agreement, a Participant may not change or revoke any election made in the Deferred Share Agreement (notwithstanding any designation of Beneficiary, which may be made any time before the distribution of the respective Deferred Shares), and may not change the election as to Entitlement Date with respect to the Participant’s respective Deferred Shares established by the respective Deferred Share Agreement, except in the case of circumstances found by the Administrator to constitute an Unforeseeable Emergency, in which event the Participant shall receive the Deferred Shares upon appropriate application to, and as deemed appropriate by, the Administrator in its sole discretion.

(b)
With the consent of the Administrator, a Participant may delay the distribution of Deferred Shares set forth in the applicable Deferred Share Agreement subject to the following requirements:

(1)
The new election, as memorialized under a new Deferred Share Agreement, may not take effect until at least 12 months after the date upon which the new election is made;

(2)
If the new election relates to payment on an Entitlement Date other than a date relating to the Participant’s death, Disability or Unforeseeable Emergency, the new election and Deferred Share Agreement must provide for the deferral of the distribution to a new Entitlement Date that is at least five years from the original Entitlement Date upon which such payment otherwise would have been made; and

(3)
The new election must be made at least 12 months prior to the original Entitlement Date.

3.3 VESTING. The rights of a Participant to distribution of his or her Deferred Shares and all receipts and expenditures attributable to the investment thereof shall at all times be and remain 100 percent vested, but only to the extent vested under the terms of the underlying Incentive Plan and the applicable Restricted Stock Award Agreement(s).

SECTION 4.
DISTRIBUTION OF DEFERRED SHARES

4.1 DISTRIBUTION. Distribution of a Participant’s Deferred Shares shall be made on the Participant’s Entitlement Date; provided, however, that if the Participant is a Specified Employee, distribution of such Participant’s Deferred Shares shall in no event occur before the date that is six months after the date that the Participant experienced a Separation from Service (other than due to the Participant’s death or Disability). Distributions shall be subject to such uniform rules and procedures as may be adopted by the Administrator.

4.2 UNFORESEEABLE EMERGENCY. A Participant may petition the Administrator for payment of all or any portion of the Participant’s Deferred Shares prior to the elected Entitlement Date upon circumstances found by the Administrator to constitute an Unforeseeable Emergency, in which event the Participant shall be permitted to receive distribution of the portion of the Deferred Shares as petitioned upon such conditions as the Administrator may reasonably determine in its sole discretion (in a manner that complies with section 409A of the Code and the regulations thereunder), provided that the amount of the Deferred Shares distributed for an Unforeseeable Emergency shall not exceed that which is reasonably needed to satisfy the financial hardship (plus such amounts as are necessary to pay any federal, state, local, or foreign income taxes or penalties reasonably anticipated to result from such payment). Any such payment shall be made as soon as administratively practicable but not earlier than the finding of the Unforeseeable Emergency. Notwithstanding the foregoing, payment may not be made for an Unforeseeable Emergency to the extent that resulting financial hardship is or may be relieved (a) through reimbursement or compensation by insurance or otherwise, or (b) by liquidation of the Participant’s assets, to the extent the liquidation of such assets would not itself cause severe financial hardship.

4.3 DESIGNATED BENEFICIARIES. A Participant may designate one or more Beneficiaries to receive all or any part of the Participant’s Deferred Shares in the event of the Participant’s death. The designation shall be effective by filing a written notification with the Administrator in such form as the Administrator may from time to time make available for such designation. The Participant’s beneficiary designation may be changed from time to time by similar action. If no such designation is made by the Participant, payments of the deceased Participant’s Deferred Shares not otherwise determined by the Payment Form shall be paid to, in the following order of priority, the Participant’s:

(a)
Surviving spouse, or if none;

(b)
Children, per stirpes, or if none;

(b)

The successor to fill any vacancy resulting from death, resignation, or removal pursuant to this Section shall be filled by designation of another person by the Employer in its sole discretion.
