RouteStep Communications Business Unit Higher Gross Margin Custom Products New business unit that manufactures its own line of custom IP communications products: Mobile IP communications node Stealth video communications surveillance Military, homeland security, law enforcement, possibly offshore oil rigs Spent $500,000 developing products in 2006; current focus on turning the business into a revenue and profit generating component of INX Recent quarter reflected first orders and first revenue; orders in hand for expectation of sequential revenue growth in current quarter Targeting 40%+ gross margin

Our Longer-Term Financial Expectations We believe the industry we are participating in is growing at 20%-30% We expect to grow faster than industry growth rates over the long run by: gaining market share because of our focus and expertise increasing revenue per customer by selling to larger customers and introducing related new offerings to customers (such as storage and security) expanding geographically (primarily through acquisitions) We have a target for operating income margin % in the range of 4% to 7%, which we expect to achieve by: improving gross margin on service revenue leveraging certain categories of operating expenses against higher revenue We currently expect to achieve the lower end of target operating profit margin percentage within several quarters

Acquisitions 3 acquisitions in past 2 years (all more than 1 year ago) All acquisitions have been successful and accretive We add value to acquired operations due to our balance sheet, industry focus and expertise and relationship with Cisco For most recently reported quarter, revenue from the acquired operations increased 101% compared to prior year period We expect to do more acquisitions of two categories: Regional firms for geographic expansion To strengthen newer “practice areas” such as storage and security

Stockholder Advantages Mass implementation of VoIP technology by enterprises should drive industry growth IP communications is a multi-billion dollar, rapidly growing market Cisco is the dominant manufacturer and INX is the only pure play public company focused on delivering Cisco VoIP solutions for enterprises Expected benefit from the increasing complexity of, and enterprise dependency upon networks Expected improving operating profit margin % = expected improved shareholder value
