3 Key Areas Of Enterprise Technology

(dollars in millions)

INX started operations in 2000 as a network infrastructure and IP Telephony solutions
provider, but has broadened its offerings over the past two years

Today our solutions offerings are in three broad categories of technology infrastructure

Data center offerings are a newer, more rapidly growing category

10

Capacity To Grow Newer Practice Areas

Market size source:IDC; VMware, based on end-user product
revenues only, excluding services;INX billings is products only

Because data center
solutions is a more recent
addition to INX’s offerings,
there is better growth
potential within INX’s
existing customers and
geographic markets

The total market is large
relative to INX’s
participation in the market

Plenty of room to grow if
we can gain market share

11

The Server Market Represents A Major Opportunity

INX entered the server virtualization market in 2008.

We have been awaiting Cisco’s release of a server product to “officially” enter the
server market.

The server worldwide market for servers, according to IDC, is $50 billion

Cisco to unveil data center strategy next Monday (March 16th)

Reuters - Monday, Mar 9, 2009 2:58pm EDT-Cisco Systems Inc said it will
unveil next week a new strategy to help customers build more efficient data
centers, amid expectations for the network equipment maker to announce it
will start selling servers….Media reports have said that Cisco plans to sell
computer servers equipped with virtualization software by VMWare Inc, a
move that could position Cisco into more competition with Hewlett-Packard
Co and IBM…..Analysts have long speculated a new server product aimed at
data centers, which Cisco has identified as a key growth area due to the
explosion of consumer-generated content and a shift to Web-based software
in business operations….

Balance Sheet Data

(dollars in thousands)

13

Accounts Receivable

% of Total A/R Aged Over 60 Days At Month End Through Feb 2009

Primary Industry Sector A/R Aged Over 60 Days

Accounts receivables makes up the majority of non-cash tangible assets

14

Credit Availability and Liquidity

We have maintained a strong balance sheet, with $1.26 / share in cash and no
funded debt under our credit facilities

Increased operating credit facility from $50 million to $60 million in May 2008

Common stock equity raise in June 2008 - paid down all funded debt

$60 million operating credit facility with average usage of $35 to $40 million

$10 million acquisitions credit facility available with zero balance

15

Current Market Conditions-Some Benchmarks

Cisco and the two largest wholesale distributors of technology products provide
evidence of recent market weakness and a benchmark for INX performance:

16

Monthly Product Order/Contract Bookings

We anticipated an industry-wide slowdown in the early Fall of
2007 and planned accordingly.A strong rebound in customer
demand starting in April 2008, along with other factors, caused
us to conclude that the economic slowdown would be short and
shallow;a second phase of weakened customer demand in the
late Summer / early Fall of 2008 caused us realize the need to
position the company for a protracted, deeper recession.

17

Unusual Items In 4th Quarter Results

$13.1 million non-cash impairment charge:

ØResult of INX’s annual impairment analysis of goodwill and intangible assets in
accordance with GAAP

ØThe impairment was in part the result of the decline in the Company’s stock price
during the fourth quarter and in part due to decreased current and expected near-
term future cash flows from acquired operations due to the recession

ØThis non-cash charge has no impact on the Company’s existing cash balances,
working capital, debt balances, credit line availability or normal business operations

$466,000 bad debt expense primarily related to events at two customers

$311,000 charge for severance expense related to December staff reductions

$140,000 charge for settlement of the company’s only meaningful lawsuit

We recorded a number of unusual items in 4Q-2009 totaling $14.0 million

$917,000

18

Non-GAAP Earnings Reconciliation

A large non-cash impairment charge in 4Q-2008 makes financial performance
comparisons to prior period results difficult

Note:$814,000 of depreciation and amortization are not excluded from non-GAAP net
income in INX’s non-GAAP reconciliation

Long-Term Progress On Improved Shareholder Value

We made substantial progress building fundamental shareholder value over the past four
years through the end of the 3rd quarter of 2009 prior to 4Q-2009 weakness.

Improving fundamental financial performance during the current recessionary environment
will be more challenging, but we are executing a plan that we believe will result in market
share gains and relative growth.Key strategies for growth in a weak economic
environment include introducing newer practice areas such as data center offerings to new
and existing customers and gaining market share against some smaller competitors that
are impacted by the tight credit markets.

22

There Are Reasons To Be Optimistic About INX’s Long-Term Prospects
In Spite Of The Current Recession

INX is focused on delivering some of the best areas of technology, from a growth perspective

Network security issues will continue unabated, irrespective of economic conditions, and spending
is often mandated by various requirements such as HIPPA or PCI compliance

Unified communications is still in a state of relative infancy;the majority of enterprise phone
systems are still antiquated TDM PBX technology; many organizations can experience a tangible
ROI from deploying UC

Web 2.0 collaboration applications are moving into the enterprise environment, enhancing
productivity

TelePresence video communications solutions help save money by reducingtravel

Growth in network storage capacity, which occurs irrespective of economic conditions, will continue
to drive demand for storage upgrades;the evolution of storage technology is toward the IP network
whichis INX’s strength

Data center virtualization has one of the most compelling ROI metrics of any area of enterprise IT,
and delaying the deployment of virtualization because of an economic downturn is less likely

Virtualization of servers within the datacenter often requires an upgrade of the network infrastructure
within the datacenter and Cisco is leading the market in terms of product offerings for data center
networking

Cisco’s introduction of Unified Computing System and server offerings that will integrate with the
Cisco Nexus data switch products and utilize virtualization is a large opportunity

23

How We Are Addressing The Current Economic Recession

We are operating the company with an expectation that customer demand will remain soft for at
least the first half of 2009, and more likely through 2009 or even longer

Faced with an inability to forecast when economic activity and customer demand will improve, we
are trying to remain “nimble and diligent”, in order to take advantage of market conditions

Aggressively controlling costs other than direct costs of generating revenue during this period of
downturn in demand - we have already made substantial cost reductions in December

We are mindful that whatever issues INX is facing due to these difficult market conditions, some of
our competitors that have leveraged balance sheets are facing even more significant issues

Executing a plan to continue togain market share during the continuing period of soft demand:

ØFocusing on aggressive marketing of newer practice areas (virtualization, network storage,
network security, virtual disaster recovery hosting, UC application integration, and in the future,
Cisco servers), which can provide additional revenue opportunities from new and existing
customers

ØHiring high quality sales talent at a time when they will be more generally available;this will
increase costs at a time when decreased customer demand depresses revenue per customer
and revenue per employee;will help INX gain market share and help improve operating profit
several quarters in the future even if demand remains soft

ØPursuing acquisitions that have a high likelihood of being almost immediately accretive - some
potential acquisition candidates are having issues due to credit constraints

Direct employee costs were68% and 70% of total operating expenses for 2007 and 2008

Leveraging employee costs is key to improving operating profit margin;sales staff and engineering
staff are direct revenue producing staffing, and we have been able to leverage non-direct-revenue-
producing staff - key to improving profit margin

For 2008 direct revenue-producing staffing increased 36% compared to 17% increase for non-direct
revenue producing staff - key to continued organic revenue growth and leverage of costs

For 2008 total revenue increased 25% while sales staff and admin/ops staff increased only 21% and
17% respectively;service revenue increased 66% while engineering staff increased only 48%.
