B. Strategy Discussion

We believe Intergraph's software is highly relevant to the current global environment: Heightened security concerns and ever-present terrorist threats Addressed by IPS first responder software and IMGS spatial/location-based software High oil prices and tightening inventory Addressed by PPM industry-leading plant and ship design software Intergraph's markets are large & growing: Targeted software markets represent more than $2.5 billion in annual customer spend Markets have an average blended annual growth rate in the 5-10% range Intergraph is a truly global company with a strong customer base: Customers in more than 60 countries with nearly 50% of revenue generated outside U.S. Strong customer relationships from history of technological innovation & leadership, high- level of customer support and commitment to customer success Primary Strategic Opportunities

Intergraph's relatively higher cost structure & lower software revenue content have led to lower overall operating margins: Development costs of software company, but revenue heavily weighted towards services Decentralized organizational structure presents operating expense challenges Increasing software content and lowering overall cost structure is a strategic priority Intergraph perceived to be collection of disparate assets: We believe significant synergies exist between our business units Delivering the entire value of the Company's assets for the benefit of both our customers and shareholders is a strategic priority Intergraph has not grown as fast as the markets we serve: Revenue growth suffered during transition from hardware to software & services business (primary focus was on returning to profitability) Accelerating revenue growth by capitalizing on our attractive market dynamics is a strategic priority Primary Strategic Challenges

Corporate Strategies: FOCUS assets and management on software-led growth CONSOLIDATE operations to realize revenue synergies between business units and reduce operating expenses INVEST internally and through acquisitions where market size is significant, returns are appropriate and growth is apparent Business Unit Strategies: Business unit roles/focus under strategic plan: IMGS: "Improve" operating margins through focus on industry-specific geospatial markets PPM: "Grow" business by becoming lifecycle solution provider to process industry ISG: "Focus" more heavily on INGR product/market-based projects for the U.S. Government IPS: "Build" integrated software suite/channel for Public Safety & Homeland Security markets Key Strategic Initiatives
