Long-Term Growth Strategies Continue geographic expansion Continue to grow both the number and the size of clients Continue to make strategic, accretive acquisitions Continue expanding into complementary categories of technology such recent as network security & network storage focused practice areas

Increasing Number and Size of Customers We serve U.S. "enterprise" organizations - corporate, state and local government, federal government, and education - with 200 to 50,000 employees As we have become more of a "national" scope organization, we have been able to win larger customers and transactions As we continue to grow our national presence we believe our ability to win larger-sized customers will continue to be enhanced

Staffing Trends Dec 31, 2004 +156% +278% Dec 31, 2007 % Incr. Mar 31, 2008 % Incr. +0% +11% Recent Quarter Long-Term Trend Since starting national expansion in 2005, with over 3x increase in markets served, staffing has increased substantially in areas related to growth, but we have leveraged growth of administrative and operations staff relative to revenue producing staff; for 2007, direct employee costs were 68% of total operating expenses, so leveraging employee costs is key to improving operating profit margin

Gross Margin Product vs. Services Revenue Sources Product gross margin has trended upward slightly over a multi-year period, a function of our increasingly high value-add solutions and increasing business from repeat customers Services gross margin declined in 2005 and 2006 due to rapid national expansion and start-up of new practice areas, both of which increased engineering and other categories of costs of service in advance of service revenue production; improving recently as benefits are realized; Q1-2008 was near mid-point of target of 30%-35% 2003 2004 2005 2006 1H-07 2H-07 Q1-08 Products 0.145 0.151 0.157 0.186 0.175 0.177 0.182 Services 0.296 0.334 0.25 0.21 0.267 0.302 0.321

Gross and Operating Profit Margin Gross profit margin on total revenue has trended slightly upward over the past several years due to improving mix of service revenue and improving gross margin on both product revenue and service revenue; in Q1-2008 this trend continued Operating profit margin turned positive in 2004, then declined in 2005 and 2006 as we executed on rapid geographic expansion and introduced new practice areas, but improved in 2007 and for MRQ as benefits of expansion began to be realized 2003 2004 2005 2006 1H-07 2H-07 Q1-08 Gross Margin 0.159 0.181 0.173 0.195 0.187 0.194 0.204 Operating Profit Margin -0.006 0.023 0.014 0.011 0.014 0.02 0.03 * 2005 results exclude one-time non-cash charge of $5.7 million

Balance Sheet Data (Dollars in thousands)

Outlook - 3 Drivers Of Recent Industry-Wide Slowdown Are Subsiding Since ~ July 2007, customers have been fearful of the possibility of a recession - - while not fully resolved, there are some signs that customers are beginning to look forward to the possibility of an improving economy in 6-12 months Since ~ July 2007, large enterprise customers have been anticipating the benefits of lower interest rates as the Fed began an easing cycle - the easing cycle appears to be near an end, which should prompt some customers to move forward with capital expenditure projects Since ~ December 2007, corporate enterprise customers began to anticipate the possibility of a Federal government economic stimulus package containing provisions to stimulate capital spending by businesses - this was signed into law in February 2008

Recent Catalysts For Continued Growth Recent services contract of $8.4 million, majority of which will be recognized over the remainder of 2008 calendar year - increase in higher margin service revenue Recent Cisco relationship achievements present opportunities: Telepresence Advanced Technology Partner; Master of Security; Cisco Powered Managed Services Partner Year-ago introduction of network storage and network security as primary practice areas beginning to yield results - (242% and 58% growth respectively for 2007) Data center trends (storage, iSCSI, FBOE) combined with Cisco's recent new product announcements in this area (Nexus line) is creating new growth opportunities Boston-based Select, Inc. acquisition is at the end of its ~6-9 month typical integration period, following which we have normally see above-average revenue growth from past acquisitions Continued recent investment in hiring of revenue-generating employees - engineering staff +18% and sales staff + 3% in Q1-2008
