This Amendment No. 1 to Tender Offer Statement on Schedule TO amends and supplements the statement originally filed on March 6, 2007 by RISCO Ltd., a limited company, organized under the laws of Israel (“RISCO”), and Rokonet Industries, U.S.A., Inc., a New York corporation and an indirect wholly-owned subsidiary of RISCO (the “Purchaser”). This Schedule TO relates to the offer by the Purchaser to purchase all outstanding shares of common stock, par value $0.01 per share (the “Shares”), of International Electronics, Inc., a Massachusetts corporation (“IEI”), at $3.50 per Share, net to the seller in cash, upon the terms and subject to the conditions set forth in the Offer to Purchase, dated March 6, 2007 (the “Offer to Purchase”) and in the related Letter of Transmittal, copies of which are attached hereto as Exhibits (a)(1)(A) and (a)(1)(B), respectively (which, together with any amendments or supplements thereto, collectively constitute the “Offer”). Pursuant to General Instruction F to Schedule TO, the information set forth in the Offer to Purchase and in the related Letter of Transmittal is incorporated herein by reference with respect to Items 1 through 9 and 11 of this Schedule TO.

The Offer to Purchase is amended as follows:

The response to the question “What does the board of directors of IEI think of the offer?” is hereby deleted and replaced with the following in the Summary Term Sheet (page ii):

“On March 16, 2007, IEI filed a solicitation/recommendation statement with the Securities and Exchange Commission on Schedule 14D-9 announcing that its board of directors had unanimously determined at a meeting duly held on March 16, 2007 that RISCO’s Offer was inadequate and not in the best interests of IEI shareholders (other than Risco and its affiliates). IEI’s board of directors recommended that IEI shareholders reject the Offer and not tender their Shares.”

The following paragraph from page 1 is hereby deleted:

“According to the Company’s Quarterly Report on Form 10-QSB filed on January 11, 2007 with the Securities and Exchange Commission (the “SEC”), as of January 5, 2007, there were outstanding 1,738,931 Shares. RISCO currently beneficially owns 500 Shares, such Shares represent less than 1% of the outstanding Shares.”

The following paragraph replaces such deleted paragraph on page 1:

“According to IEI’s response to the tender offer filed on Schedule 14D-9 on March 16, 2007 with the Securities and Exchange Commission (the “SEC”), as of February 28, 2007, there were outstanding 1,746,931 Shares. RISCO currently beneficially owns 500 Shares, such Shares represent less than 1% of the outstanding Shares.”

In Section 10, “Background of the Offer”:

• The date “November 15, 2006” is hereby changed to “November 14, 2006” where it appears.

• The date “December 5, 2006” is hereby changed to “December 4-6, 2006” where it appears.

• The date “February 1, 2007” is hereby changed to “January 31-February 1, 2007” where it appears.

And, the following is hereby inserted at the end of such Section 10:

“On March 16, 2007, IEI filed a solicitation/recommendation statement with the SEC on Schedule 14D-9 announcing that its board of directors had unanimously determined at a meeting duly held on March 16, 2007 that RISCO’s Offer was inadequate and not in the best interests of IEI shareholders (other than RISCO and its affiliates). IEI’s board of directors recommended that IEI shareholders reject the Offer and not tender their Shares. IEI also indicated that it would call a special meeting of IEI shareholders on April 25, 2007 under Chapter 110D of the Massachusetts General Laws, or the Massachusetts Control Share Acquisition Statute, in order to determine whether to authorize voting rights for any shares acquired by RISCO and the Purchaser in the Tender Offer.”

On March 20, 2007, RISCO filed a Preliminary Proxy Statement with the Securities Exchange Commission and issued a press release and an open letter to IEI shareholders.”
