Revenue shortfall of $4 million compared to our mid-June expectations: Growth from Integrated Materials Sales Traction from commercial shipments of recently introduced 3-D Printers Abnormally higher used-equipment sales Lower unit volume from sales of Large-Frame systems Higher deferred service and warranty revenue Continued impact of uncertain economy Gross profit margin shortfall primarily on volume, mix and COGS drivers: Changes in revenue mix and volume resulting in under absorbed overhead High incidence of used-equipment sales reducing gross profit on weighted basis Amounts associated with our initial planned build up of V-Flash(r) finished goods inventory Higher warranty costs Duplicate supply-chain costs related to move from 3PL provider to Rock Hill Unfavorable net effect of foreign currency translation on cost of goods sold Factors Shaping 2Q08 Results 8 Combined revenue mix and COGS including FX negatively affected gross profit by approximately 500 basis points.

19 Progress Report Abe Reichental President & CEO

20 State of Business We believe and expect that: Notwithstanding the uncertain current economic climate, our sales recovered somewhat in the second quarter of 2008, and we are well positioned to gain additional lost ground in the coming quarters. Our growing installed base, coupled with the integration of our new systems with proprietary materials' cartridges, should improve the profitability of our business as revenue from materials continues to outpace the growth in systems. The stability of our revenue base should improve as consumables' sales rise as a percentage of the product mix relative to systems. In the absence of abnormally high used equipment sales that we experienced in 2Q08, gross profit margins should improve. We believe that despite the uncertain economy and slower demand for parts our Integrated Materials Strategy is working.

We did not recognize revenue during the first half of 2008 from any V-Flash(r) activities. We commenced selected shipments of V-Flash(r) desktop modelers in early July after successfully resolving the electrical noise problems that previously halted this phase. Consistent with our previously announced plan, we anticipate a continued managed phased rollout through the end of 2008. We believe that our internal delays are not indicative of marketplace demand for this product. Due to the relative low price per unit and managed rollout plan, we do not anticipate the V-Flash(r) Desktop Modeler to be a material revenue contributor during 2008. V-Flash(r) Desktop 3-D Printer Update We expect that commercial V-Flash(r) shipments will suppress our gross profit margins by $0.5 million to $1.0 million per quarter for the near term. 21

Revenue Upside to Reverse First-Half Shortfall Opening the Japanese marketplace to our key Accura(r) materials Commercial shipments of two new professional, high-definition 3-D printers: The ProJet(tm) HD 3000 3-D Production System The ProJet(tm) DP 3000 3-D Dental Professional System Commercial shipments of two direct metal laser sintering systems: The New Sinterstation(r) Pro DM100 SLM System The New Sinterstation(r) Pro DM250 SLM System Pursuing direct digital dentistry opportunities with 3M, Sirona, SensAble... We expect that incremental revenue from these growth initiatives will help mitigate first-half revenue shortfall. 22

Additional SG&A Reduction Initiatives Curtail certain budgeted discretionary expenses Absence of certain special accounting costs Conclusion of contractor provided services Receipt of available South Carolina job development incentives Normalize annual audit and tax review cost Absence of expansive recruitment and relocation costs Deliver operating cost savings from Rock Hill consolidation Expect selling expenses to rise with revenue Expect SG&A expenses to continue to decline at a slower rate due to anticipated marketing and legal expenses. 23

Gross Profit Improvement Plan Update Profit Leakage Source Inefficient third-party logistics and warehousing. Material weaknesses related to inventory management. Inefficient parts return system inflating inventory and cost of goods. Premature failures of warranty parts supplied by third parties. Negative FX impact on materials produced in Europe. Action Completing move to Rock Hill in August 2008. P&L benefit to begin Q3. Integrated ERP module, moved activity in-house. Streamlining process, move activity in-house. Improving third-party supplied parts quality. Completed a resin blending facility in Rock Hill. P&L benefit to begin Q3. 24 Third-party logistics partner strategy did not deliver expected results; it caused the company significant profit leakage.

Progress Against Our Long-Term Target Model (% of Yearly Revenue, $ in millions) 25 We believe that continued integrated materials revenue growth coupled with the decline of SG&A and the realization of our gross profit improvement plan will result in returning and exceeding our historical performance in these categories and convergence to the threshold of our target operating model. 2003 2006 2004 2005 2007 6 Mos 08 TOM* 6 Mos 07 39% 45% 45% 34% 41% 46% 40% 39% Gross Profit 44% 31% 29% 38% 35% 25% 41% 37% SG&A 8% 8% 9% 10% 9% 8% 9% 10% R&D 29% 30% 32% 39% 40% 42% 41% 46% Materials Revenue $110.0 $125.6 $139.1 $134.8 $156.5 $170.0 $73.4 $68.4 Revenue TOM = Target Operating Model
