                      [Preformed Line Products Letterhead]

                                                                  March 10, 2003

Mr. Randy Ruhlman
Ruhlman Motor Sports
2530 Brandt Forest Court
Greensboro, NC  27455

Hi Randy:

Dan, Terry and I had a great time at the Tampa-St. Pete event. We enjoyed the
hospitality that you and Cristi made available to us and our customers. Clearly,
hosting smaller groups in the paddock area is more cost effective. Besides, in
my view, it's more exciting to be right there witnessing all of the action as
the cars are being readied for the event.

As we discussed, Preformed Line Products is committed to paying a sponsorship
fee of $658,000 for the 2003 season to Ruhlman Motorsports. I know of no other
practical method to reach and partner with our customers in such an exciting,
but cost effective, manner.

Enclosed is the first payment of $300,000 to be credited towards the 2003
sponsorship fee. The payment schedule for the remainder of the 2003 fee is as
follows:

                              APRIL 2003 - $158,000
                              MAY 2003 - $100,000
                              JUNE 2003 - $100,000

Randy, we look forward to employing this unique venue as an exciting way to
build stronger relationships with many of our key customers. We like these
events because you and your staff are very focused on our customers. You always
take the time to shower the customers with special attention while providing any
information requested about you, the equipment and the event. We're building
strong memories with our customers that we hope will result in additional PLP
product purchases now and in the future.

We look forward to working with you and your staff this season.

                                           Best regards,

                                           Jon Barnes

                                CREDIT AGREEMENT

      This Consolidated Amendment No. 1 to Credit Agreement (this "Amendment"),
dated as of October 31, 2002, is entered into by and between PREFORMED LINE
PRODUCTS COMPANY ("Borrower") and NATIONAL CITY BANK ("Bank").

                                   WITNESSETH:

      WHEREAS, the parties have entered into a Credit Agreement dated December
30, 1994, as amended by First Amendment to Credit Agreement dated as of November
30, 1997 (the "First Amendment") and Second Amendment to Credit Agreement dated
as of July 6, 2000 (the "Second Amendment") (as amended, the "Credit Agreement";
all terms used in the Credit Agreement being used herein with the same meaning);
and

      WHEREAS, the parties desire to further amend certain provisions of the
Credit Agreement to (a) decrease the amount of the subject commitment to
$20,000,000.00, (b) change the interest rate and (c) amend certain covenants;
and

      WHEREAS, in light of the fact that certain terms set forth in previous
amendments have been affected by later amendments and/or will be affected by
this Amendment and for ease of reference, the parties also desire to restate and
consolidate in this Amendment all amendments to the Credit Agreement that are
effective on and as of the date hereof;

      NOW, THEREFORE, in consideration of the foregoing and the mutual covenants
and agreements contained herein and for other good and valuable consideration,
the receipt and sufficiency of which is hereby acknowledged, the parties agree
as follows:

SECTION I - AMENDMENTS TO CREDIT AGREEMENT

A.      Subsections 2A.01 through 2A.05 of the Credit Agreement are hereby
amended in their entirety to read as follows:

      2A.01 AMOUNT -- The amount of the subject commitment is twenty million and
      00/100ths dollars ($20,000,000.00), but that amount may be reduced from
      time to time pursuant to subsection 2A.03 and the subject commitment may
      be terminated pursuant to section 5B.

      2A.02 TERM -- The subject commitment shall commence as of the date of this
      Agreement and shall remain in effect on a revolving basis through January
      1, 2006 (the expiration date) EXCEPT that a later expiration date may be
      established from time to time pursuant to subsection 2A.05 and EXCEPT that
      the subject commitment shall end in any event upon any earlier reduction
      thereof to zero pursuant to subsection 2A.03 or any earlier termination
      pursuant to section 5B.

<PAGE>
      2A.03 OPTIONAL REDUCTIONS -- Borrower shall have the right, at all times
      and without the payment of any premium, to permanently reduce the amount
      of the subject commitment by giving Bank one banking day's prior written
      notice of the amount of each such reduction and the effective date thereof
      subject, however, to the following:

            (a) No such reduction shall reduce the subject commitment to a
            lesser aggregate amount than the sum of the aggregate unpaid
            principal balance of the fixed-rate loans then outstanding plus the
            aggregate undrawn face amounts of the outstanding subject LCs plus
            the aggregate unpaid principal balance of any fixed-rate loans and
            aggregate face amounts of any subject LCs to be obtained pursuant to
            any unfulfilled credit request under subsection 2B.02.

            (b) Concurrently with each reduction Borrower shall prepay such
            part, if any, of the principal of the subject loans then outstanding
            as may be in excess of the amount of the subject commitment as so
            reduced. Subsection 2B.13 and section 6C shall apply to each such
            prepayment.

      2A.04  COMMITMENT FEE -- Borrower agrees to pay Bank a commitment fee

            (a) based on the average daily difference between the amount of the
            subject commitment from time to time in effect and the aggregate of
            the unpaid principal balance of all subject loans then outstanding
            plus the undrawn face amount of all outstanding subject LCs,

            (b) computed (on the basis of a 360-day year and the actual number
            of days elapsed) at a rate of one-fifth of one percent (1/5%) per
            annum so long as the subject commitment remains in effect and

            (c) payable in arrears on October 1, 2002 and on the first day of
            each January, April, July and October thereafter and at the end of
            the subject commitment.

      2A.05 EXTENSION OF SUBJECT COMMITMENT -- Whenever Borrower furnishes its
      audited financial statements to Bank pursuant to clause (b) of subsection
      3A.01, commencing with Borrower's audited financial statements for its
      fiscal year ending December 31, 2002, Borrower may request that the
      subject commitment be extended one year to the December 31 next following
      the expiration date then in effect. Bank agrees to give consideration to
      each such request; but in no event shall Bank be committed to extend the
      subject commitment, nor shall the subject commitment be so extended,
      unless and until both Borrower and Bank shall have executed and delivered
      an extension agreement substantially in the form of Exhibit C with the
      blanks appropriately filled.

B.     Clauses (a) and (b) of subsection 2B.11 are hereby amended in their

            applicable contract period plus one percent (1%) per annum.

            (b) Prior to maturity each LIBOR loan shall bear interest at a rate
            equal to the LIBO pre-margin rate in effect at the start of the

            3B.01 NET WORTH -- Borrower will not suffer or permit the
            consolidated net worth (exclusive of the cumulative foreign currency
            translation adjustment component thereof as reflected in Borrower's
            financial statements) of the companies at any time to be less than
            the required minimum amount in effect at the time in question. The
            required minimum amount shall be one hundred twenty million dollars
            ($120,000,000) EXCEPT that that amount shall be permanently
            increased as of the end of each fiscal quarter of Borrower by an
            amount equal to fifty percent (50%) of Borrower's consolidated net
            income, if any, after taxes, for the quarter then ending. The
            determination of Borrower's net worth shall exclude the amount, if
            any, of Borrower's after-tax loss on the sale of Superior Modular

                  four (4) quarters plus

                  (b)  the aggregate interest expense of the companies for the
                  previous four (4) quarters plus

                  the companies for the previous four (4) quarters

            to be less than an amount equal to three hundred percent (300%) of
            the aggregate interest expense of the companies for the previous
            four quarters, all as determined on a consolidated basis.

                liquidation of a subsidiary,

                (b) lease as lessor, sell, sell-leaseback or otherwise transfer
                (whether in one transaction or a series of transactions) all or
                any substantial part of its fixed assets EXCEPT chattels that
                shall have become obsolete or no longer useful in its present
                business,

                (c) except for the merger transactions permitted under clause
                (a) of this subsection, purchase or otherwise acquire all or
                substantially all of the capital stock or the assets and
                business of any corporation or other business enterprise if the
                aggregate amount of all such purchases and acquisitions would
                exceed $20,000,000 for any one transaction or $30,000,000 in the

F.        The following new section 2C is hereby added to the Credit Agreement:

          2C. LETTERS OF CREDIT -- Bank agrees that so long as the subject
          commitment remains in effect Bank will issue such letters of credit

          to time request subject, however, to the conditions of this Agreement.

                2C.01 MAXIMUM -- Bank shall not issue any subject LC if, after
                giving effect thereto,

                    (a) the aggregate undrawn balance of all then outstanding
                    subject LCs would exceed five hundred thousand dollars

        2C.03  FORM -- Each subject LC shall

            (a)  be issued in such form as Bank may reasonably require,

            importation of goods in the ordinary course of Borrower's business
            or a standby letter of credit, and

            (c)  be denominated in United States dollars.

        2C.04 COMMISSION -- Borrower shall pay Bank at the issuance of each
        subject LC a non-refundable commission equal to

        to, and to deliver on Borrower's behalf an appropriate credit request
        requesting a RR loan in an amount equal to the reimbursement amount plus
        any interest thereon. Bank will make the requested RR loan even if any
        default under this agreement shall then exist under the Agreement and
        even if Borrower for any other reason would then not be entitled to
        obtain any subject loan. Bank shall disburse all such loan proceeds
        directly to Bank to satisfy Borrower's reimbursement liability.

        2C.07 UNCONDITIONAL OBLIGATION -- The obligation of Bank to make, and of
        Borrower to pay, the RR loans made pursuant to the preceding section
        shall be absolute and unconditional and shall be performed under all
        circumstances, including (without limitation)

               that Bank may have against Borrower or any of its affiliates or

               successors in interest,

               such subject LC or

               (e) any payment of any draft or other item by Bank which does not
               strictly comply with the terms of such subject LC provided such
               payment shall not have constituted gross negligence or willful
               misconduct.

G.    The following new subsection 5B.04 is hereby added to the Credit
Agreement:

      5B.04 SUBJECT LCs -- If the maturity of the subject indebtedness shall be

      reimburse Bank for any then outstanding subject LCs, cash or acceptable
      marketable securities having a fair cash value equal to the sum of the
      aggregate undrawn balance of any then outstanding subject LCs. For this
      purpose, acceptable marketable securities include only those referred to
      in clause (v) of subsection 3D.02.

H.    Section 6H of the Credit Agreement is hereby renumbered section 6I and
the following new subsection 6H is hereby added to the Credit Agreement:

      6H. INDEMNITY: MISCELLANEOUS COSTS/SUBJECT LCs -- Borrower agrees to
      defend and indemnify Bank against, and to hold Bank harmless from, any
      loss, liability, damage, claim, cost, or expense relating to Bank's
      issuance or maintenance of any subject LC or to Bank's payment of any
      draft drawn thereunder, excluding any such loss, liability, damage, claim,
      cost, or expense resulting from Bank's gross negligence or willful
      misconduct.

I.     Section 6I is hereby amended in its entirety to read as follows:

      be paid, and the computations and assumptions in determining the amount,
      which certificate shall be presumed to be correct in the absence of
      manifest error. In determining the amount of any such payment, Bank may

except as specifically set forth herein. From and after the date of this

                 AMENDED AND RESTATED PROMISSORY NOTE

$20,000,000.00           _________ , Ohio           __________ , 2002

FOR VALUE RECEIVED, the undersigned, PREFORMED LINE PRODUCTS COMPANY, an Ohio
corporation, ("Borrower"), promises to pay to the order of NATIONAL CITY BANK
("Bank"), at the address specified on the bills received by Borrower from Bank
(or at such other place as Bank may from time to time designate by written
notice), the principal sum of

                     TWENTY MILLION AND 00/100THS DOLLARS

(or, if less, the aggregate unpaid principal balance from time to time shown on
the reverse side hereof or as may be entered in a loan account on Bank's books
and records, or both), together with interest computed in the manner provided in
the Credit Agreement referred to below, which principal and interest is payable
in accordance with provisions in the Credit Agreement.

This note is issued pursuant to a Credit Agreement dated as of December 30,
1994, as amended from time to time (as amended, the "Credit Agreement") by and
between Borrower and Bank. This note is issued in substitution for that certain
$20,000,000.00 Tranche A Promissory Note and that certain $20,000,000.00 Tranche
B Promissory Note, both dated as of November 30, 1997 (collectively, the "Old
Note"). This Note is not intended as a novation of the obligations of Borrower
under the Old Note but rather is merely a restatement of the obligations
thereunder after giving effect to the most recent amendment to the Credit
Agreement.

Reference is made to the Credit Agreement for the definitions of certain terms,
for provisions governing the making of subject loans, the acceleration of the
maturity thereof, rights of prepayment, and for other provisions to which this
note is subject. Any endorsement by the payee on the reverse side of this note
(or any allonge thereto) shall be presumptive evidence of the data so endorsed.
