SPECIAL MEETING OF THE STOCKHOLDERS

INTERNATIONAL ELECTRONICS, INC.

TO BE HELD ON [APRIL 25], 2007

PROXY STATEMENT

OF

RISCO LTD. AND

ROKONET INDUSTRIES, U.S.A., INC.

SOLICITATION OF PROXIES IN FAVOR OF VOTING RIGHTS

UNDER CHAPTER 110D OF THE MASSACHUSETTS GENERAL LAWS

This Proxy Statement (the “Proxy Statement”) and the enclosed BLUE proxy card are furnished by RISCO Ltd., an Israeli limited company (“RISCO”), and Rokonet Industries, U.S.A., Inc., a New York corporation and wholly-owned subsidiary of RISCO (“Purchaser”) (for convenience purposes, throughout this Proxy Statement, we sometimes refer to RISCO as the party soliciting proxies in connection herewith), in connection with RISCO’s solicitation of proxies to be used at a special meeting (the “Special Meeting”) of stockholders of International Electronics, Inc., a Massachusetts corporation (“IEI”), to be held on [April 25], 2007, at [IEI’s corporate headquarters at 427 Turnpike Street, Canton, Massachusetts 02021] at [            ] A.M. Eastern Time, and at any adjournments, postponements or reschedulings thereof. IEI has set [            ], 2007 as the record date for determining those stockholders who will be entitled to vote at the Special Meeting (the “Record Date”). The principal executive offices of IEI are located at 427 Turnpike Street, Canton, Massachusetts 02021. This Proxy Statement and the enclosed BLUE proxy card are first being mailed to IEI’s stockholders on or about [            ], 2007.

RISCO and Purchaser are soliciting proxies to authorize, in accordance with Chapter 110D of the Massachusetts General Laws (“Chapter 110D”), the acquisition by RISCO or Purchaser (or one or more corporations directly or indirectly wholly-owned by RISCO) of common shares, par value $0.01 per share of IEI (the “Shares”) that, when added to all other Shares in respect of which RISCO and Purchaser may exercise or direct voting power in the election of IEI’s directors, would entitle RISCO and Purchaser to exercise a majority or more of such voting power.

On March 6, 2007, Purchaser offered to purchase (the “Offer”) all of the outstanding Shares of IEI for $3.50 net per Share in cash upon the terms and subject to the conditions set forth in an Offer to Purchase dated March 6, 2007, as the same may be amended from time to time (the “Offer to Purchase”) and the related Letter of Transmittal.

As more fully described below under “Massachusetts Control Share Acquisition Statute,” Chapter 110D requires stockholder authorization to be obtained for the Shares acquired by the acquiring person in a proposed Control Share Acquisition (as defined below) to have the same voting rights as all other shares of the issuing public corporation. The Special Meeting of stockholders of IEI has been called by IEI’s Board of Directors pursuant to Chapter 110D for the specific purpose of voting on whether the Shares acquired by Purchaser or RISCO (or one or more corporations directly or indirectly owned by RISCO) as contemplated by and in accordance with the terms and conditions of the Offer to Purchase will have voting rights (the “Voting Rights Proposal”). IEI has indicated that the Special Meeting will be scheduled to be held on [April 25, 2007] at a time and place to be announced by IEI in the notice of the Special Meeting to be sent by IEI to IEI stockholders.

Shares may not be accepted for payment pursuant to the Offer unless (i) the Shares acquired by Purchaser pursuant to the Offer are authorized by the stockholders of IEI at the Special Meeting to have voting rights, or (ii) Purchaser, in its sole discretion, is satisfied that the provisions of Chapter 110D are invalid or inapplicable to such acquisition. Accordingly, if you want the opportunity to receive $3.50 net per Share in cash pursuant to the Offer, you should authorize the Voting Rights Proposal.

Your vote is important! Please sign, date and return the accompanying BLUE proxy card today. If you want the opportunity to receive $3.50 net per Share in cash pursuant to the Offer, we urge you to sign and mail promptly the enclosed proxy in favor of the Voting Rights Proposal.

Stockholder authorization of the Voting Rights Proposal will not require you to tender your shares to Purchaser. Consummation of the Offer, however, is conditioned upon authorization by IEI stockholders of the Voting Rights Proposal to the extent required by law. Accordingly, it is important that stockholders who wish to tender their Shares to Purchaser pursuant to the Offer vote for the authorization of the Voting Rights Proposal on the enclosed BLUE proxy card.

1

Tendering Shares pursuant to the Offer will NOT constitute a vote in favor of the Voting Rights Proposal. Instead you must vote by using the enclosed BLUE proxy card or by voting in person at the Special Meeting.

If you have any questions about the voting of Shares, the Offer or the Voting Rights Proposal, please call MacKenzie Partners, Inc., Toll free: 1-800-322-2885, In New York: 1-212-929-5500 (call collect).

Reasons to Vote “FOR” the Voting Rights Proposal

• A vote “FOR” the Voting Rights Proposal gives you the opportunity to receive a premium at $3.50 per Share, in cash, for a stock that is generally illiquid.

There is no established trading market for the Shares. The Shares are traded in the Over-the-Counter Bulletin Board (the “OTCBB”) under the symbol “IEIB.OB.” The Offer represents:

• a premium of almost 170% over the lowest trading price of the Shares during the past twelve months of $1.30;

• a premium of more than 106% over the last trading price before RISCO’s written offer to IEI on October 31, 2006 of $1.70;

• a premium of almost 90% over the average trading price of the Shares from March 15, 2005 through October 31, 2006 of $1.86; and

• a premium of 17% over the reported closing price for the Shares on the OTCBB on March 5, 2007, the day before the Offer was first publicly disclosed.

In addition, the stock is extremely illiquid with an average daily trading volume from March 15, 2005 through October 31, 2006 of approximately 4,169 shares. The Offer is subject to certain terms and conditions described in the Offer to Purchase. A copy of the Offer to Purchase dated March 6, 2007 accompanies this Proxy Statement.

• A vote “FOR” the Voting Rights Proposal gives YOU the right to decide whether or not to tender your shares as part of the Offer.

If the Voting Rights Proposal is not authorized by the IEI stockholders at the Special Meeting, then Shares will not be accepted for payment pursuant to the Offer unless (i) Purchaser is satisfied, in its sole discretion, that the provisions of Chapter 110D are invalid or inapplicable to the acquisition by Purchaser of Shares pursuant to the Offer or (ii) Purchaser, in its sole discretion, waives that condition to the Offer. By voting in favor of the Voting Rights Proposal, a stockholder is not required to tender Shares in the Offer, stockholder authorization of the Voting Rights Proposal simply gives you the opportunity to sell your shares to Purchaser pursuant to the Offer. Management has repeatedly chosen not to disclose the terms of RISCO’s offers to IEI stockholders, and by so doing has denied you the ability to decide as to whether you wish to receive a premium on your shares. A vote “FOR” the Voting Rights Proposal puts this decision back in your hands.

• A vote “FOR” the Voting Rights Proposal gives YOU a concrete alternative to management’s speculative strategic plan.

IEI has indicated, apparently without the benefit of advice from a recognized financial advisor, that RISCO’s offer is inadequate because it does not take into account the long-term value of management’s turn-around strategy. RISCO believes that IEI’s current strategy is incapable of delivering the results management hopes for. IEI’s product offering is too narrow and the global market place is too competitive, with customers demanding more and more systems integration, which IEI as a smaller company, is challenged to offer. IEI lacks the resources for significant investment in R&D, sales channel growth, distribution and product support necessary to implement its strategy successfully. IEI lacks the resources to effectively compete with many of its competitors, including Honeywell, Tyco, Bosch or Siemens, or even smaller competitors such as Hirsch, DSX, Keri or ACI. The conditions to RISCO’s offer, by any objective measure, are much less significant, more concrete, more achievable and more certain than the conditions associated with management’s proposed alternative to RISCO’s offer-management’s execution of its speculative strategic plan.

The Offer

On March 6, 2007, Purchaser commenced the Offer. The purpose of the Offer is to acquire control of, and the entire equity interest in, IEI. RISCO currently intends, as soon as practicable after consummation of the Offer, to seek maximum representation on IEI’s Board of Directors and to seek to have IEI consummate a merger or other similar business combination with RISCO (or one of RISCO’s subsidiaries).

The Offer is not subject to RISCO obtaining third-party financing or completing customary due diligence review of IEI’s operations. The Offer is subject to certain terms and conditions described in the Offer to Purchase. A copy of the Offer to Purchase dated March 6, 2007 accompanies this Proxy Statement.

On March 16, 2007, the Board of Directors of IEI recommended that IEI stockholders reject the Offer. Subsequently, RISCO issued a press release and mailed an open letter to IEI stockholders indicating its disappointment in IEI’s recommendation.

The Schedule TO, which includes the Offer to Purchase and was filed by Purchaser and RISCO with the SEC on March 6, 2007, and all amendments thereto may be inspected at the public reference room maintained by the SEC at 100 F Street, N.E., Washington, D.C. 20549. Copies of such materials can also be obtained at prescribed rates from the public reference room of the SEC at 100 F Street, N.E., Washington, D.C. 20549, or free of charge on the SEC website: http://www.sec.gov. Please call the SEC at 1-800-SEC-0330 for further information on the operation of the public reference room.

2

If the Voting Rights Proposal is not authorized by the IEI stockholders at the Special Meeting, then Shares will not be accepted for payment pursuant to the Offer unless Purchaser is satisfied, in its sole discretion, that the provisions of Chapter 110D are invalid or inapplicable to the acquisition by Purchaser of Shares pursuant to the Offer or Purchaser, in its sole discretion, waives that condition to the Offer.

By voting in favor of the Voting Rights Proposal, a stockholder is not required to tender Shares in the Offer and would not be prohibited from later voting against any other proposed control share acquisition or business combination involving IEI, RISCO or Purchaser. Stockholder authorization of the Voting Rights Proposal, to the extent required by law, would simply give you the opportunity to sell your shares to purchaser pursuant to the Offer.

Voting at the Special Meeting

At the Special Meeting, stockholders will be asked to authorize the Voting Rights Proposal, which requires (i) the affirmative vote of the holders of a majority of all the Shares entitled to vote generally in the election of directors, excluding Interested Shares (as defined below) and (ii) the presence of a quorum at the Special Meeting. A quorum shall be deemed to be present at the Special Meeting if at least a majority of the Shares excluding those that are Interested Shares, are represented at such meeting in person or by proxy.

RISCO has requested that the following question be posed to IEI stockholders, to authorize the Voting Rights Proposal:

Question:

Should any Shares acquired by Rokonet Industries, U.S.A., Inc., a New York corporation and wholly-owned subsidiary of RISCO Ltd., pursuant to its currently outstanding tender offer as described in the Offer to Purchase, dated March 6, 2007, as it may be amended from time to time, and any Shares thereafter beneficially acquired in such “control share acquisition” by Rokonet, RISCO or any of their “associates” (as defined in Chapter 110D of the Massachusetts General Laws), be entitled to the same voting rights as all other shares of Common stock?

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, each of which (excluding Interested Shares) is entitled to one vote on the Voting Rights Proposal.

A vote in favor of the Voting Rights Proposal will not require that you tender shares in the Offer. It will afford stockholders an opportunity to decide for themselves whether to accept the Offer. A stockholder of record on the Record Date will be entitled to vote at the Special Meeting even if such stockholder has tendered such stockholder’s shares in the Offer.

Whether or not you plan to attend the Special Meeting, we urge you to vote FOR authorization of the Voting Rights Proposal by so indicating on the accompanying BLUE proxy card and immediately mailing it in the enclosed envelope. You may revoke your proxy at any time prior to its exercise by revoking at the Special Meeting and voting in person, by submitting a duly executed, later dated proxy by one of the methods provided on your proxy card or by submitting a written notice of revocation to either (a) RISCO, care of MacKenzie Partners, Inc., 105 Madison Avenue, New York, New York 10016, or (b) the principal executive offices of IEI at 427 Turnpike Street, Canton, Massachusetts 02021. A revocation may be in any written form validly signed by the record holder as long as it clearly states that the proxy previously given is no longer effective. Stockholders who hold their shares in a bank or brokerage account will need to notify the person responsible for their account to revoke or withdraw previously given instructions. We request that a copy of any revocation sent to IEI or any revocation notification sent to the person responsible for a bank or brokerage account also be sent to RISCO, care of MacKenzie Partners, Inc., at the address below so that RISCO may more accurately determine if and when proxies have been received from the holders of record on the record date of a majority of IEI’s Shares then outstanding. Unless revoked in the manner set forth above, subject to the foregoing, duly executed proxies in the form enclosed will be voted at the Special Meeting in accordance with your instructions. In the absence of such instructions, such proxies will be voted FOR the Voting Rights Proposal.

Abstentions

Any abstention from voting on a proxy which has not been revoked will count as a vote withheld, and thus will have the same practical effect as a vote “AGAINST,” yet will be included in computing the number of Shares present for purposes of determining whether a quorum is present at the Special Meeting.

3

Broker Non-Votes

Brokers or other nominees who hold Shares in “street name” for customers who are beneficial owners of such Shares may not give a proxy to vote those customers’ Shares in the absence of specific instructions from those customers. These non-voted Shares will not be counted as votes cast or shares voting and will have the same effect as votes “AGAINST” the Voting Rights Proposal, yet will be included in computing the number of Shares present for purposes of determining whether a quorum is present at the Special Meeting.

Massachusetts Control Share Acquisition Statute

Chapter 110D provides, in general and subject to certain exceptions, that shares of “public corporations” (those having (1) 200 or more stockholders of record, (2) a principal executive office, or substantial assets, within Massachusetts, and (3) either more than ten percent of its stockholders of record residing within Massachusetts or more than ten percent of its issued and outstanding shares owned of record by Massachusetts residents) acquired in a Control Share Acquisition will not have voting rights unless voting rights for such shares are authorized at an annual or special meeting of stockholders of the corporation by the affirmative vote of the holders of a majority of all the shares entitled to vote generally in the election of directors, excluding those shares (1) beneficially owned by any person who has acquired or proposes to acquire shares in a Control Share Acquisition, (2) shares held by officers of the corporation, and (3) shares held by directors who are also employees of such corporation (the “Interested Shares”).

As used in Chapter 110D “Control Share Acquisition” means, in general, the acquisition (other than pursuant to an agreement of merger or consolidation to which the subject corporation is a party) of beneficial ownership of shares of a corporation that (but for the provisions of the statute) would have voting rights and that, when added to all other shares of such corporation beneficially owned by such person, would entitle such person, upon acquisition of such shares, to vote or direct the voting of shares of such corporation having voting power in the election of directors within any of the following ranges of such voting power: (i) one-fifth or more but less than one-third of all voting power; (ii) one-third or more but less than a majority of all voting power; or (iii) a majority of all voting power.

Any person who proposes to make or has made a Control Share Acquisition may deliver to the corporation at its principal office a statement (a “Control Share Acquisition Statement”) containing (1) the identity of the acquiring person and such person’s holdings in the corporation prior to the Control Share Acquisition, (2) the number of shares proposed to be acquired by such person pursuant to the Control Share Acquisition, (3) describing the terms and conditions of the Control Share Acquisition, and (4) representing that the acquiring person has the financial capacity to consummate the Control Share Acquisition. If the acquiring person so requests at the time of delivery of a Control Share Acquisition Statement, the board of directors of the corporation is required to call a special meeting of stockholders for the purpose of considering the voting rights to be accorded to shares acquired or to be acquired in the Control Share Acquisition. Such special meeting is required to be called within 10 days after such corporation receives the request and the Control Share Acquisition Statement and must be held not more than 50 days after the request has been received. Notice for such special meeting must also be given not less than 20 days before the date of the special meeting. RISCO and Purchaser delivered a Control Acquisition Statement to IEI on March 6, 2007.

The issuing public corporation is required to send a notice of the special meeting as promptly as reasonably practicable to all stockholders of record as of the record date set for such meeting, together with a copy of the Control Share Acquisition Statement and such other information as such corporation deems appropriate.

The shares acquired by the acquiring person in the proposed Control Share Acquisition will only have the same voting rights as all other shares of the issuing public corporation if authorized by vote of the stockholders of the corporation at a meeting at which a quorum is present. Such authorization requires the affirmative vote of a majority of the voting power entitled to vote generally in the election of directors, excluding Interested Shares.

Dissenters’ Rights

Dissenters rights are not available to stockholders of an issuing public corporation in connection with the approval of the Voting Rights Proposal. In the event that the Voting Rights Proposal is approved, the other conditions to the Offer are satisfied and Purchaser consummates the Offer and a subsequent merger, certain stockholders may be entitled to appraisal rights in accordance with Section 13 of Chapter 156D of the Massachusetts Business Corporation Act. Any stockholder who desires to exercise appraisal rights should carefully review Chapter 110D and Chapter 156D of the Massachusetts Business Corporation Act and is urged to consult a legal advisor before exercising or attempting to exercise such rights.

4

The foregoing summary of Chapter 110D and Chapter 156D of the Massachusetts Business Corporation Act does not purport to be complete and is qualified in its entirety by reference to the provisions of Chapter 110D, the Massachusetts General Laws and the Massachusetts Business Corporation Act.

Other Matters

Except as set forth herein, neither RISCO nor Purchaser is aware of any other substantive matter to be considered at the Special Meeting. However, if any other matter properly comes before the Special Meeting, the proxies also confer authority to the persons named in the accompanying proxy to vote the Shares to which the proxy relates on such matter at their discretion.

A copy of the Control Share Acquisition Statement delivered to IEI by Purchaser and RISCO accompanies this Proxy Statement. The Control Share Acquisition Statement and the Offer to Purchase contain important information and should be read by stockholders before any decision is made with respect to voting on the Voting Rights Proposal.

Only holders of record of Shares as of the close of business on the Record Date will be entitled to vote. If you are a stockholder of record on the Record Date, you will retain your voting rights for the Special Meeting even if you sell such Shares after the Record Date or if you tender such Shares pursuant to the Offer, whether before or after the Record Date. The tender of Shares pursuant to the Offer does not constitute the grant to RISCO or Purchaser of a proxy or any voting rights with respect to the tendered Shares until such time as such Shares are accepted for payment by Purchaser. Accordingly, it is important that you vote the Shares held by you on the Record Date, or grant a proxy to vote such Shares on the BLUE proxy card even if you sell such Shares after the Record Date or tender such Shares pursuant to the Offer.

If any of your Shares are held in the name of a brokerage firm, bank, bank nominee or other institution on the Record Date, only it can execute a proxy for such Shares and will do so only upon receipt of your specific instructions. Accordingly, please contact the person responsible for your account and instruct that person to execute the BLUE proxy card.

Please sign, date and mail the accompanying BLUE proxy card promptly. No postage is required if mailed in the United States. By signing and mailing the accompanying BLUE proxy card, any proxy previously signed by you with respect to the Voting Rights Proposal will be automatically revoked.

Background of the Solicitation

In early 2004, RISCO and IEI discussed a possible business combination or joint venture on a few occasions. RISCO indicated that it would value IEI in any such transaction in the range of $3.8-5.7 million, depending on the outcome of RISCO’s due diligence review. IEI rejected this proposal and did not respond to RISCO’s invitation to discuss a joint venture.

On July 5, 2006, Moshe Alkelai, the Chairman of RISCO’s Board of Directors and RISCO’s Chief Executive Officer, met with John Waldstein, the Chairman of IEI’s Board of Directors and IEI’s President and Chief Executive Officer, in Boston, Massachusetts. At this meeting Mr. Alkelai reiterated RISCO’s interest in acquiring IEI and indicated RISCO would also be willing to employ Mr. Waldstein on a long-term basis to operate the business. In the weeks that followed, Mr. Waldstein did not respond to RISCO’s proposal.

5

On August 30, 2006, Mr. Alkelai sent a letter to Mr. Waldstein indicating RISCO’s interest in acquiring IEI for a price equal to $2.50 per share, subject to due diligence but not to obtaining third-party financing. The August 30 proposal letter read as follows:

August 30, 2006

Mr. John Waldstein

President and Chief Executive Officer

International Electronics, Inc.

427 Turnpike Street

Canton, MA 02021

RE: Acquisition Proposal

Dear John:

As discussed at our meeting last month, RISCO Group has been carefully considering the possible acquisition of International Electronics, Inc. (“IEI”).

Based on a preliminary investigation of publicly available information, we would be prepared to acquire IEI at a price equal to U.S. $2.50 per issued and outstanding share on the date hereof. RISCO Group has adequate cash reserves on hand to eliminate any financing contingency in a definitive agreement.

We believe this price maximizes the value of IEI and therefore it would be in the best interest of your company and its shareholders to pursue discussions concerning this potential acquisition. We will contact you shortly for that purpose.

Of course, the proposed acquisition referenced herein is subject to and conditioned upon: (i) the negotiation and execution of a binding written agreement in a form and substance acceptable to RISCO Group and its counsel; (ii) the completion by RISCO Group and its counsel of a customary due diligence investigation of IEI to the satisfaction of RISCO Group; and (iii) the receipt of all necessary and appropriate corporate and government approvals.

It is also understood that neither RISCO Group nor IEI will be held responsible for expenses incurred or opportunities forgone by the other in reliance of this letter or the transactions contemplated hereby.

We look forward to the opportunity to work together to consummate this transaction on a friendly and negotiated basis.

Very truly yours,

/s/ Moshe Alkelai

Moshe Alkelai

Chairman of the Board

On or around September 14, 2006, in an e-mail to Lior Samuelson of Mercator Capital RISCO’s financial advisor, Mr. Waldstein indicated that after discussing the matter with IEI’s Board of Directors, IEI was not interested in pursuing such a transaction. He did suggest that he meet with Mr. Alkelai at a trade show in the United States and discuss a potential joint venture project. Instead, Mr. Alkelai invited Mr. Waldstein to visit RISCO in Israel for meetings. Mr. Waldstein replied that he would respond to Mr. Alkelai after the trade show. Mr. Waldstein never responded to Mr. Alkelai.

On October 25, 2006, the Purchaser acquired 500 shares of IEI common stock for $1.60 per share.

6

On October 31, 2006, RISCO delivered an offer to acquire all of the outstanding shares of IEI for $2.70 per share. Such offer was not conditioned on due diligence or obtaining third-party financing. In addition, RISCO submitted a demand for IEI to convene a stockholders’ meeting prior to December 20, 2006 under the Massachusetts Control Share Acquisition Statute to authorize voting rights for any shares RISCO proposed to acquire in such transaction. The October 31 proposal letter read as follows:

October 31, 2006

John Waldstein

Chairman of the Board of Directors

President and Chief Executive Officer

International Electronics, Inc.

427 Turnpike Street

Canton, Massachusetts 02021

Dear John:

I am pleased to present an offer on behalf of RISCO Group Ltd. (“Risco”) to acquire all of the outstanding common stock of International Electronics, Inc., a Massachusetts corporation (the “Company”), for a price per share of US$2.70 per share. Our offer represents a premium over the last sale price of the Company’s common stock on October 27, 2006 of about 70%.

Our proposal represents an outstanding opportunity to the Company, its Board of Directors, stockholders and employees at a critical juncture. The Company’s stock price and revenues have been largely flat or trending downward for several years. The Company has been delisted from NASDAQ and its common stock is extremely illiquid. The Company is on its third outside auditor in 18 months and undoubtedly faces increased burdens of being a public company in light of Sarbanes-Oxley and addressing public company issues driven by news headlines (such as option issuance practices). While the Company may be working hard to execute its strategic plan, there is little evidence that the plan promises to deliver stockholders a return on their investment approaching the immediate return our offer will provide. Our proposal also offers the Company and its employees an exciting opportunity to join a leading multinational integrated security and building management company with a proven track record of successful growth.

We note that our proposal is an all cash offer and is not subject to any financing contingency or due diligence review of the Company (but is subject to the conditions set forth in Paragraph 5 of the enclosed control share acquisition statement). Our proposal offers Company stockholders immediate liquidity at a significant premium to market that will maximize their investment in the Company, given its current financial position and outlook. Please note that our offer of $2.70 per share is based on the share and option counts disclosed in the Company’s public filings.

Risco, via its wholly-owned subsidiary Rokonet Industries U.S.A Inc, has recently acquired 500 shares of Company’s common stock and has initiated a “control share acquisition” within the meaning of Chapter 110D of the Massachusetts General Laws (the “Control Share Statute”). We have enclosed a “control share acquisition statement” required by the Control Share Statute. Risco hereby demands that the Company convene a special meeting of its stockholders to authorize voting rights for the shares of Company common stock Risco acquires in the control share acquisition as required by § 4 of the Control Share Statute. In accordance with § 4 of the Control Share Statute, the Company must call the special meeting within 10 days of the date hereof and the meeting must be held not later than 50 days after the date hereof, or December 20, 2006.

In order to avoid disputes, we recommend that our respective legal counsels confer as soon as possible on the text of the proposed stockholder resolution and other technical matters related to the meeting. Risco hereby undertakes to pay all reasonable expenses of the Corporation incurred in connection with the special meeting, but not including any expenses incurred opposing the vote to authorize voting rights for the shares we intend to acquire.

While Risco would much prefer to engage in a consensual transaction with the Company, and believes a consensual transaction would potentially create more value for Company stockholders, Risco cannot accept the Company’s continued refusal to negotiate seriously with us. We note that we have previously made an offer to acquire the Company in a letter, dated August 30, 2006, but

7

have received no formal response. If you do not contact us to negotiate a consensual transaction along the lines outlined in this letter and the attached control share acquisition statement by November 7, 2006, we will assume that the Company has rejected our offer. If we cannot negotiate a consensual transaction, Risco will evaluate all of its options, including taking its case directly to the Company’s stockholders.

Risco is very serious about its proposal to acquire the Company. We are ready to meet with Company Board of Directors and its representatives as soon as possible. We have retained Mercator Capital as our financial advisor and Bingham McCutchen LLP as our legal counsel to advise us in this matter. Please contact me, at 972-3-9637777 (e-mail: moshe@riscogroup.com), Lior Samuelson of Mercator Capital, at 703995-5525 (e-mail: lsamuelson@mercatorcapital.com), or John Utzschneider of Bingham McCutchen LLP at 617-951-8852 (e-mail: john.utzschneider@bingham.com) to discuss any questions you might have.

Very truly yours,

/s/ Moshe Alkelai

Moshe Alkelai

Chairman of the Board

On November 14, 2006, Mr. Waldstein, Mr. Alkelai, Lesley Charm, a member of IEI’s Board of Directors, and Lior Samuleson, RISCO’s financial advisor, met in Boston at the offices of Bingham McCutchen LLP, RISCO’s counsel, to discuss RISCO’s October 31 offer. At the meeting, however, Mr. Waldstein and Mr. Charm indicated they were unwilling to discuss the terms of RISCO’s offer and the meeting ended inconclusively.

On November 30, 2006, at IEI’s request, RISCO agreed to rescind its demand for IEI to convene a stockholder’s meeting under the Massachusetts Control Share Acquisition Statute to authorize voting rights for any IEI shares RISCO acquires. Mr. Waldstein planned a trip to visit RISCO’s offices in Israel to discuss RISCO’s possible acquisition of IEI and Mr. Waldstein’s potential employment by RISCO.

On December 4 and 5, 2006, Mr. Waldstein met with Mr. Alkelai at RISCO’s offices in Israel, but refused to discuss any terms of a potential acquisition.

On January 31 and February 1, 2007, Mr. Waldstein, Mr. Charm, Mr. Alkelai and Mr. Samuelson met again in Boston to discuss a potential transaction, but Messrs. Waldstein and Charm refused to discuss the terms of any offer.

On March 6, 2007, RISCO launched the Offer to acquire all outstanding Shares of IEI for $3.50 per share. The Offer is not conditioned on due diligence or obtaining third-party financing. In addition, RISCO submitted a demand for IEI to convene a stockholders’ meeting prior to April 25, 2007 under the Massachusetts Control Share Acquisition Statute to authorize voting rights for any shares RISCO proposed to acquire in such transaction. The March 6 proposal letter read as follows:

March 6, 2007

Board of Directors

International Electronics, Inc.

427 Turnpike Street

Canton, Massachusetts 02021

Ladies and Gentlemen:

RISCO Ltd. (“RISCO”), beneficial owner of 500 shares of International Electronics, Inc. common stock, has commenced a tender offer to acquire, subject to certain conditions, all of the outstanding shares of International Electronics, Inc. (“IEI”) at a price of $3.50 per share in cash through its wholly-owned subsidiary, Rokonet Industries, U.S.A., Inc. (“Rokonet USA”).

8

RISCO has attempted to discuss an amicable transaction with IEI management on several occasions over the past several months, and submitted a written acquisition offer for $2.70 per share on October 31, representing a premium over the then trading price of IEI shares of more than 75%. Our proposals have not been met with serious discussion. IEI’s refusal to negotiate with us in good faith has left us no choice but to commence our current offer at this time.

Rationale for Offer.

Our offer represents a premium over the last sale price of IEI’s common stock on March 5, 2007 of more than 17% and a premium over the last sales price of IEI common stock on October 31, 2006, the date of our last offer to acquire IEI, of more than 106%.

As we have maintained in our discussions with IEI management, we believe it is in the best interests of IEI stockholders to enter into a negotiated and definitive acquisition agreement as soon as possible. Unfortunately, to date IEI management has deprived IEI stockholders of an opportunity to make their own decision with respect to a sale of their shares by refusing to discuss our proposal with us in any detail.

Our proposal represents an outstanding opportunity to IEI, its Board of Directors, stockholders and employees at a critical juncture. IEI has generated net losses in each of 12 of its most recent 13 fiscal quarters and its stock price has been largely flat or trending downward for several years, excluding the period following our October 31 offer. IEI has been delisted from NASDAQ and its common stock is extremely illiquid. IEI is on its third outside auditor in less than two years and undoubtedly faces increased burdens of being a public company in light of Sarbanes-Oxley and addressing public company issues driven by news headlines (such as option issuance practices). While IEI may be working hard to execute its strategic plan, there is little evidence that the plan promises to deliver stockholders a return on their investment approaching the immediate return our offer will provide. Our proposal also offers IEI and its employees an exciting opportunity to join a leading multinational integrated security and building management company with a proven track record of successful growth.

Demand for Meeting.

RISCO hereby reiterates its demand that IEI convene a special meeting of its stockholders to authorize voting rights for the shares of IEI common stock RISCO and Rokonet USA acquire in the tender offer, which would constitute a “control share acquisition” within the meaning of Chapter 110D of the Massachusetts General Laws (the “Control Share Statute”). We have enclosed a “control share acquisition statement” required by the Control Share Statute. In accordance with § 4 of the Control Share Statute, IEI must call the special meeting within 10 days of the date hereof and the meeting must be held not later than 50 days after the date hereof, or April 25, 2007.

In order to avoid costly delays and disputes, we recommend that our respective legal counsels confer as soon as possible on the text of the proposed stockholder resolution and other technical matters related to the meeting. RISCO hereby undertakes to pay all reasonable expenses of IEI incurred in connection with the special meeting, but not including any expenses incurred opposing the vote to authorize voting rights for the shares we intend to acquire.

Demand for Stockholder List.

In addition, we have enclosed a demand, under Rule 14d-5(a) of the Securities Exchange Act of 1934, as amended (the “Securities Exchange Act”), to receive from IEI its most recently prepared stockholder list or, if such list was prepared as of a date earlier than ten business days before the date hereof, a newly prepared list as of the most recent practicable date, which shall be no more than ten business days prior to the date hereof. Your timely response in accordance with Rule 14d-5(a) of the Securities Exchange Act should be directed to the individuals named below.

9

Demand for Inspection Rights.

Finally, we also demand access to IEI to inspect and copy certain IEI records as permitted by Section 16.02 of the Massachusetts Business Corporation Act. Our demand includes access to a list of IEI stockholders (including their names and addresses showing the number of shares each holds, as well as all information in IEI’s possession relating to the beneficial owners of IEI shares (commonly referred to as the “NOBO” list)), the bylaws of IEI, including all amendments, and excerpts from minutes reflecting action taken at any meeting of the board of directors, records of any action of a committee of the board of directors while acting on behalf of the corporation, minutes of any meeting of the stockholders, and records of any action taken by the stockholders or board of directors without a meeting, in each case within the last three years. We request that these records be made available to RISCO and its representatives not later than March 13, 2007. The purposes of our demand are several, including (i) to better ensure dissemination of our offer to all stockholders, (ii) to communicate with fellow stockholders regarding the matters described in our control share acquisition statement and their voting thereon, and (iii) potentially soliciting proxies in order to change management and/or the by-laws of IEI. To the extent any such records contain material, nonpublic information, RISCO is prepared to enter into a suitable confidentiality agreement on customary terms to permit disclosure of such information.

We call your attention to the provisions of Massachusetts law imposing liability on corporate officials who improperly fail to comply with requests such as those made in this letter.

Notwithstanding the commencement of our offer and the enclosed demands, we continue to be ready to meet with the IEI Board of Directors and its representatives as soon as possible to discuss our offer. Please contact Lior Samuelson of Mercator Capital, at 703-995-5525 (e-mail: lsamuelson@mercatorcapital.com), or John Utzschneider of Bingham McCutchen LLP at 617-951-8852 (e-mail: john.utzschneider@bingham.com) to discuss any questions the Board might have.

We continue to believe our offer represents the best opportunity for IEI stockholders to realize value on their shares. We urge you to facilitate the ability of the IEI stockholders to make their own decision as to whether they agree with our view. If the IEI Board of Directors and management continue to try to obstruct our offer, we are prepared to take all steps necessary to ensure that IEI stockholders have the opportunity to benefit from it.

Very truly yours,

/s/ Moshe Alkelai

Moshe Alkelai

Chairman of the Board

On March 16, 2007, IEI issued a press release and filed a response to the Offer on Schedule 14D-9, recommending that IEI stockholders reject the Offer and not tender their Shares.

On March 20, 2007, RISCO issued a press release and an open letter to IEI stockholders that reads as follows:

March 20, 2007

Stockholders of

International Electronics, Inc.

Dear Fellow Stockholders:

On March 6, 2007, RISCO Ltd. (“RISCO”) through its wholly-owned subsidiary, Rokonet Industries, U.S.A., Inc., commenced a tender offer to acquire all of the outstanding shares of International Electronics, Inc. (“IEI”), subject to certain conditions, at a price of $3.50 per share in cash. We were forced to launch our offer without the support of IEI’s board of directors or management because, despite our repeated attempts to negotiate a consensual transaction, IEI has stonewalled and refused to engage in serious discussion with us.

We were disappointed, but not surprised, to learn that last week IEI decided to oppose our offer. Once again, when presented an opportunity to create value for all stockholders, the IEI board and management has dug in its heels and refused to do so.

IEI offers two principal reasons why it opposes our offer. First, IEI management says our offer is inadequate, takes advantage of a temporary depression of the company’s stock price based on 2006 operating results and does not reflect the long-term value of the company based on management’s 2-1/2 year old strategic plan to turn the company around. Second, IEI says our offer is highly conditional.

10

In response to the first concern regarding the long-term prospects of IEI under current management’s direction, we can only point out the following:

• In our view, IEI’s current strategy is incapable of delivering the results management hopes for. IEI’s product offering is too narrow and the global market place is too competitive, with customers demanding more and more systems integration, which IEI as a smaller company, is challenged to offer. IEI lacks the resources for significant investment in R&D, sales channel growth, distribution and product support necessary to implement its strategy successfully. IEI lacks the resources to effectively compete with many of its competitors, including Honeywell, Tyco, Bosch or Siemens, or even smaller competitors.

• IEI has not generated positive net income in any of the last three fiscal years. According to its publicly filed financial statements, it has actually lost money for 11 of 12 consecutive quarters ending August 31, 2006, over $2.2 million in the aggregate, or $1.33 per share (more than 2-1/2 times the cumulative net income of IEI for the three fiscal years prior to 2004). While IEI points to recent positive earnings of $0.15 per share for the six months ended February 28, 2007 as ratification of its strategy, it would take another 4-1/2 years to recoup the losses accumulated during the previous three years at the current rate.

• We understand that IEI has yet to retain a recognized financial advisor to advise the board as to what the current value of management’s speculative long-term strategy is. Our question is, how does management know our offer does not reflect full value for IEI? In all of our preceding discussions, management has never once indicated what an appropriate, nonspeculative valuation of the company would be.

• There has been no significant trading market for IEI’s common stock since it was delisted from Nasdaq in July 2005. Management has not indicated that it is even a goal of the company to again qualify for listing. Management seems content for IEI and its stockholders to bear all of the additional expense and burden of being a public company, without stockholders being entitled to the corresponding benefits of a liquid market for their shares. Management has only begun making customary earnings announcements since we commenced our offer.

• As reflected in the attached Exhibit, our offer of $3.50 per share is almost twice the $1.86 average share price of IEI common stock during the period March 15, 2005 through October 31, 2006, the date of our offer to the IEI board of directors, which IEI elected not to disclose publicly to its stockholders. During such period, daily trading volume averaged just 4,169 shares. Trading activity and the price of IEI shares have increased since our offer, with public records reflecting one stockholder coincidentally acquiring a significant position. However, we believe the share price and trading volumes would revert to their historic levels should our offer not be consummated.

In response to the board’s second concern, that our offer is highly conditioned, we point out that:

• Most of the conditions to our offer are a direct result of management’s refusal to negotiate with us. Management could eliminate the most significant of our conditions by engaging in discussions with us and supporting our offer, including the conditions related to the Massachusetts Control Share Acquisition Statute and the Massachusetts Business Combination Statute.

• The conditions to our offer, by any objective measure, are much less significant, more concrete, more achievable and more certain than the conditions associated with management’s proposed alternative to our offer—management’s execution of its speculative strategic plan.

• We continue to strive to reduce or eliminate conditions to our offer. It is not conditioned upon RISCO obtaining third-party financing or customary due diligence review of IEI’s operations. We have no interest in not consummating our offer.

Soon, you as an IEI stockholder can help us satisfy one of our conditions. Today we filed preliminary proxy statement and related materials with the Securities Exchange Commission (the “SEC”) for a special meeting IEI has indicated it intends to call on April 25, 2007 regarding our proposal under the Massachusetts Control Share Acquisition Statute. If you and a sufficient number of other IEI stockholders vote FOR our proposal at that meeting, we will be entitled to exercise voting rights with respect to any IEI shares we acquire in our offer. Such an outcome would satisfy one of our conditions and preserve your ability to take advantage of our offer.

On the other hand, if holders of a majority of outstanding IEI shares either vote against our proposal or do not vote their shares, any IEI shares we might otherwise acquire in our offer may not have voting rights that we can exercise. Such an outcome would significantly detract from our ability to realize value in IEI shares that we would like to purchase and could prevent you from taking advantage of our offer. We believe that, should our offer not be consummated, over time, IEI shares would revert to their historical trading prices and volumes.

Once we are permitted to do so by the SEC, we will send you a definitive proxy statement and other materials describing our proposal in more detail with instructions on how you can vote your IEI shares.

This communication may be deemed to be solicitation material in respect of the solicitation of proxies of Rokonet Industries, U.S.A., Inc. from stockholders of IEI in connection with the special meeting of IEI stockholders expected to be held on April 25, 2007. Rokonet Industries, U.S.A., Inc. will file a definitive proxy statement on Schedule 14A. IEI STOCKHOLDERS SHOULD READ THOSE MATERIALS CAREFULLY BECAUSE THEY CONTAIN IMPORTANT INFORMATION REGARDING RISCO’S PROPOSAL. Stockholders will be able to obtain the proxy statement and related materials with respect to the special meeting free at the SEC’s website at www.sec.gov or from Rokonet Industries, U.S.A., Inc. by contacting Mackenzie Partners, Inc. toll free at 1-800-322-2885 or collect at 1-212-929-5500 or via email at proxy@mackenziepartners.com.

Rokonet Industries, U.S.A., Inc. and its directors and executive officers may be deemed to be participants in the solicitation of proxies from the holders of IEI common stock in respect of the proposed special meeting of stockholders. Certain information about such persons and their interest in the solicitation will be contained in the proxy statement regarding the special meeting, when it becomes available.

We look forward to the IEI special meeting on April 25 and encourage you to attend in person or by proxy. Vote your shares, preserve your options.

Very truly yours,

/s/ Moshe Alkelai

Chairman of the Board
