IEIB has incurred significant losses in the past three years

–

Aggregate per share losses for FY 2004-2006 equal $1.33 per share

–

At an earnings rate of $0.28 per share, IEIB will need 4.75 years to recoup previous losses

Management has not put forth a clear strategy that articulates how they can recoup these

losses with such limited resources at their disposal

IEIB Management Comments

Management’s guidance have been overly optimistic and have not

delivered on prior commitments to create shareholder value

“We look forward to the efforts that have been made in both product development

and expansion of our channels of distribution to pay dividends in fiscal 2006.”

–

John Waldstein, Chairman & CEO, November 28, 2005

“The Company continues to believe that the markets and the opportunities afforded

it by the development of the eMerge™

and the Powerkey™

product lines are

significant.”

–

John Waldstein, Chairman & CEO, January 17, 2006

“Our flagship product line, the eMerge

Browser Managed Security Platform,

continues to do well as more dealers adopt it as their product of choice in security

management.”

IEIB Issues

Marginal player with very limited product offering

–

IEIB does not own the IP for its “flagship”

product

Weak management team that has consistently failed to deliver

–

John Waldstein is the Chairman, CEO, President, CFO and Treasurer

Weak corporate governance structure

–

Unaccountable management team and Board

–

BOD does not have a governance or nominating committee

–

Audit committee composed of only 2 members

–

Board has 4 members including one insider

Limited liquidity and institutional shareholder base

–

The company has been traded on the over-the-counter market since July of

2005

–

Average recent

(1)

daily trading volume is 3,200

–

Two institutional shareholders representing 10.4% of the outstanding shares

–

Management has given no indication that it is working to get IEI

shares re-

listed on Nasdaq and create liquidity for stockholders

IEIB Issues

Limited financial wherewithal to embark on growth and strategic

initiatives

–

As of February 28, 2007, IEIB had $1.1mm in cash

–

The company does not have adequate financial resources to augment its

product offerings and develop a robust sales and distribution channel

required to compete in today’s competitive marketplace

–

The company continues to squander its limited financial resources by

resisting to consider a full and fair proposal by Risco

IEIB’s claim that Risco’s offer is “substantially less”

than other offers is

undocumented

IEIB has proven to be unwilling to consider the interests of its

shareholders and negotiate a consensual transaction

IEIB is not well positioned to create near or long-term shareholder

value

Risco Offer for IEIB

Risco’s offer for IEIB does not include conditionalities that are

often found in similar proposals including:

–

Financing contingencies

–

Completion of due diligence

–

Approval by Buyer’s stockholders

–

Tender by sufficient stockholders for “back end”

merger

–

Registration of Buyer securities in non-cash deal

Risco’s only “unique”

conditions are:

–

50.1% tender

–

Approval of voting rights

–

Satisfaction of business combination statute

Risco’s offer for IEIB minimizes uncertainties

Risco Offer for IEIB

A significant premium

All cash

High degree of certainty

No financing or other contingencies

Risco believes that the proposal it has put forward for IEIB is

adequate and is in the best interest of shareholders
