         This Amendment No. 1 (this "Amendment") amends and supplements the
Tender Offer Statement on Schedule TO filed with the Securities and Exchange
Commission on July 10, 2000 by NS Acquisition Corp., a Delaware corporation
("Purchaser"), and Heico Holding, Inc., a Delaware corporation ("Parent"). The
Schedule TO relates to the offer by Purchaser to purchase any and all
outstanding shares of Common Stock, par value $.01 per share, of
National-Standard Company, an Indiana corporation (the "Company"), at a purchase
price of $1.00 per share, net to the seller in cash, without interest thereon,
upon the terms and subject to the conditions set forth in the Offer to Purchase
dated July 10, 2000 (the "Offer to Purchase"), and in the related Letter of
Transmittal (which, together with any amendments or supplements thereto,
collectively constitute the "Offer"), copies of which have been filed as
Exhibits (a)(1)(i) and (a)(1)(ii) to the Schedule TO, respectively, and which
are incorporated herein by reference.

         All information in the Offer to Purchase, including all schedules
thereto, is incorporated by reference in answer to all of the items in this
Statement. Capitalized terms used but not otherwise defined herein shall have
the meanings ascribed to them in the Schedule TO and the Offer to Purchase.
Except as amended and supplemented hereby, the Schedule TO remains in effect.

ITEMS 1 THROUGH 9 AND ITEMS 11 THROUGH 13

Items 1 through 9 and Items 11 through 13 of the Schedule TO, which incorporate
by reference the information contained in the Offer to Purchase, are hereby
amended and supplemented as follows:

         The Section of the Offer to Purchase entitled "Introduction" is hereby
amended and supplemented to insert the following at the end of the ninth
paragraph:

         "U.S. Bancorp Piper Jaffray has consented to the references to its
         fairness opinion in this Offer to Purchase."

         The Section of the Offer to Purchase entitled "Questions and Answers
about the Offer and the Merger" is hereby amended and supplemented to insert the
following after the third sentence of the paragraph under the heading "How Long
Do I Have to Decide Whether to Tender in the Offer?":

         "Such purchases would be made during a subsequent offering period in
         which the shares would be purchased as they are tendered. We do not
         intend to accept shares tendered after the expiration date except in
         connection with a subsequent offering period."

         The Section of the Offer to Purchase entitled "Questions and Answers
about the Offer and the Merger" is hereby amended and supplemented by replacing
the first sentence of the paragraph under the heading "How Will I be Notified if
the Offer is Extended?" in its entirety with the following:

         "If the Offer is extended past August 4, 2000, we will make a public
         announcement of the new expiration date by issuing a press release to
         the Dow Jones News Service no later than 9:00 a.m., Eastern time, on
         the next business day."

         The Section of the Offer to Purchase entitled "Questions and Answers
about the Offer and the Merger" is hereby amended and supplemented to insert the

Object to the Price Being Offered, Will I Have Appraisal Rights?":

         "The shares may no longer be eligible for quotation on the American

         holders of round lots, the aggregate market value of publicly held
         shares or the stockholders equity of the Company falls below the
         guidelines prescribed by the American Stock Exchange. If the offer is
         consummated, the number of shareholders of the Company may be so small
         that the shares may not be eligible for trading on the American Stock
         Exchange or any other national securities exchange."

amended and supplemented to insert the following at the end of the seventh

         Section 4 of the Offer to Purchase ("Withdrawal Rights") is hereby
amended and supplemented to insert the following at the end of the first
paragraph:

         "If Purchaser provides a Subsequent Offering Period, tendering
         shareholders will not have withdrawal rights during the Subsequent
         Offering Period and Purchaser will promptly purchase and pay for any
         Shares tendered at the same price paid in the Offer. Shares tendered
         prior to the Expiration Date may not be withdrawn during a Subsequent
         Offering Period."

replace the last sentence of the sixth paragraph with the following:

         "Such chief executive officer indicated that any merger discussions
         with the Company should be deferred to some time in the future because

         another transaction at that time."

         Section 10 of the Offer to Purchase ("Background of the Offer and the
Merger; Contacts with the Company") is hereby amended and supplemented to delete
the words "consistent with its October 1998 proposal" in the second sentence of
the third paragraph.

         Section 10 of the Offer to Purchase ("Background of the Offer and the
Merger; Contacts with the Company") is hereby amended and supplemented to insert
the following after the first sentence of the twenty-eighth paragraph:

         "Parent suggested a cash merger because of its concerns, as well as
         those expressed to it by the Company and its representatives, that in
         light of the significant issues that existed concerning the structure
         and terms of a stock transaction, the parties would be unable to reach
         an agreement on the terms of such a transaction in a timely manner."

is hereby amended and supplemented to delete the phrase "the acceptance of such
Shares for payment or the payment therefor" in the first sentence and replace
such phrase with "the expiration of the Offer."

         Section 14 of the Offer to Purchsae ("Certain Conditions of the Offer")
