Exhibit (a)(5)(B)

This announcement is neither an Offer to Purchase nor a solicitation of an Offer to sell Shares (as defined

below). The Offer (as defined below) is being made solely pursuant to the Offer to Purchase, dated

March 6, 2007, and the related Letter of Transmittal (and any amendments or supplements

thereto), and is being made to all holders of Shares. The Purchaser (as defined below) is not

aware of any state where the making of the Offer is prohibited by any administrative or

judicial action or pursuant to any valid state statute. If the Purchaser becomes aware of

any valid state statute prohibiting the making of the Offer or the acceptance of the

Shares pursuant thereto, the Purchaser will make a good faith effort to comply with

such statute or seek to have such statute declared inapplicable to the Offer. If,

after such good faith effort, the Purchaser cannot comply with such state

statute, the Offer will not be made to (nor will tenders be accepted from

or on behalf of) holders of Shares in such state.

Notice of Offer to Purchase for Cash

All Outstanding Shares of Common Stock

of

International Electronics, Inc.

at

$3.50 Net per Share in Cash

by

Rokonet Industries, U.S.A., Inc.

an indirect wholly-owned subsidiary of

RISCO Ltd.

Rokonet Industries, U.S.A., Inc., a New York corporation (the “Purchaser”) and a wholly-owned subsidiary of RISCO Ltd., a limited company organized under the laws of Israel (“RISCO”), hereby offers to purchase all of the outstanding shares of common stock, par value $0.01 per share (the “Shares”), of International Electronics, Inc., a Massachusetts corporation (“IEI”), at a purchase price of $3.50 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 March 6, 2007 (the “Offer to Purchase”), and in the related Letter of Transmittal (which, as amended from time to time, together constitute the “Offer”). Tendering stockholders who have Shares registered in their names and who tender directly to Continental Stock Transfer & Trust Company (the “Depositary”) will not be charged brokerage fees or commissions. Stockholders who hold their Shares through a broker or bank should consult such institution as to whether it charges any such fees or commissions. RISCO or the Purchaser will pay all charges and expenses of MacKenzie Partners, Inc., which is acting as Information Agent for the Offer (the “Information Agent”) and the Depositary incurred in connection with the Offer.

THE OFFER AND WITHDRAWAL RIGHTS WILL EXPIRE AT 12:00 MIDNIGHT,

NEW YORK CITY TIME, ON APRIL 2, 2007, UNLESS THE OFFER IS EXTENDED.

The purpose of the Offer is to acquire control of, and the entire equity interest in, IEI. The Purchaser currently intends, as soon as practicable after consummation of the Offer, to seek maximum representation on the IEI Board of Directors and to seek to have IEI consummate a merger or other similar business combination with the Purchaser (or one of its subsidiaries). Pursuant to such merger or business combination, outstanding Shares not owned by RISCO or its subsidiaries (including the Purchaser) would be converted into the right to receive cash in an amount equal to the price per Share provided pursuant to the Offer.

The Offer is conditioned upon, among other things, (1) there being validly tendered and not withdrawn prior to the expiration date of the Offer a number of Shares which represents at least 66-2/3% of the total number of outstanding Shares (including any other IEI Shares directly or indirectly owned by RISCO) on a fully diluted basis (which assumes the conversion or exercise of all derivative securities regardless of the conversion or

exercise price, the vesting schedule or other terms or conditions thereof) on the date of purchase, and (2) RISCO being satisfied that the requirements of the Massachusetts Control Share Acquisition Statute and the Massachusetts Business Combination Statute are either inapplicable to the Offer and any potential merger or other business combination thereafter or have been satisfied. The Offer is also subject to other conditions described in the Offer to Purchase. If any such condition is not satisfied, the Purchaser may (i) terminate the Offer and return all tendered Shares to tendering stockholders, (ii) extend the Offer and, subject to withdrawal rights as set forth below, retain all such Shares until the expiration of the Offer as so extended, (iii) waive any condition and, subject to any requirement to extend the period of time during which the Offer is open, purchase all Shares validly tendered prior to the expiration of the Offer and not withdrawn, (iv) amend the Offer in any other respect by giving oral or written notice of such amendment to the Depositary or (v) delay acceptance for payment or payment for Shares, subject to applicable law, until satisfaction or waiver of the conditions to the Offer. Any such extension or amendment, as discussed above, will be followed as promptly as practicable by public announcement thereof and, in the case of such extension, no later than 9:00 a.m., New York City time on the next business day after the previously scheduled expiration of the Offer. The Offer is not conditioned upon RISCO or the Purchaser obtaining financing.

After the expiration of the Offer, if all of the conditions to the Offer have been satisfied or waived, but not 100% of the Shares have been tendered, the Purchaser may, subject to certain conditions, include a subsequent offering period of between three and 20 business days to permit additional tenders of Shares. No withdrawal rights apply to Shares tendered in a subsequent offering period, and no withdrawal rights apply during a subsequent offering period with respect to Shares previously tendered in the Offer and accepted for payment. The Purchaser does not currently intend to include a subsequent offering period, although the Purchaser reserves the right to do so.

For purposes of the Offer, the Purchaser shall be deemed to have accepted for payment tendered Shares when, as and if the Purchaser gives oral or written notice to the Depositary of its acceptance for payment of the tenders of such Shares. Payment for Shares accepted for payment pursuant to the Offer will be made only after timely receipt by the Depositary of (i) certificates for such Shares (or a confirmation of a book-entry transfer of such Shares into the Depositary’s account at the Book-Entry Transfer Facility (as defined in the Offer to Purchase)), (ii) a properly completed and duly executed Letter of Transmittal (or facsimile thereof) and (iii) any other required documents.

Tenders of Shares made pursuant to the Offer may be withdrawn at any time prior to the expiration of the Offer. Thereafter, such tenders are irrevocable, except that they may be withdrawn after May 2, 2007 unless such Shares have been accepted for payment as provided in the Offer to Purchase. To withdraw tendered Shares, a written, telegraphic, telex or facsimile transmission notice of withdrawal with respect to such Shares must be timely received by the Depositary at one of its addresses set forth on the back cover of the Offer to Purchase, and the notice of withdrawal must specify the name of the person who tendered the Shares to be withdrawn, the number of Shares to be withdrawn and the name of the registered holder of Shares, if different from that of the person who tendered such Shares. If the Shares to be withdrawn have been delivered to the Depositary, a signed notice of withdrawal with (except in the case of Shares tendered by an Eligible Institution (as defined in the Offer to Purchase)) signatures guaranteed by an Eligible Institution must be submitted prior to the release of such Shares. In addition, such notice must specify, in the case of Shares tendered by delivery of certificates, the name of the registered holder (if different from that of the tendering stockholder) and the serial numbers shown on the particular certificates evidencing the Shares to be withdrawn or, in the case of Shares tendered by book-entry transfer, the name and number of the account at the Book-Entry Transfer Facility to be credited with the withdrawn Shares.

The information required to be disclosed by paragraph (d)(1) of Rule 14d-6 of the General Rules and Regulations under the Securities Exchange Act of 1934 is contained in the Offer to Purchase and the related Letter of Transmittal and is incorporated herein by reference.
