Almost universal interest in cloud computing as part of the enterprise IT delivery mix addressing cost, speed and new capabilities. Workloads drive different rates of adoption and deployment choices – public, private and hybrid. Shared industry clouds appear attractive to many clients. IBM is uniquely positioned to address new opportunities with cloud computing

Opportunities result from global industry transformations which drive cost and complexity of IT Healthcare – There are over 4M too few doctors, nurses and support workers to meet existing demand. 1 out of 10 Americans suffer from chronic disease, and about 70% of all health care expenditures are related to these illnesses. Utilities – PG&E has ~10M meters and is moving from monthly readings to testing at 15-minute intervals, amounting to 960M transactions a day -- 29B a month that weren’t happening before. Transportation – U.S. demand for freight rail is projected to double in the next 25 years. In China, railway investments in 2009 were more than the total for the decade 1995-2005, up 79% yty.

Supplemental Benchmark Data Information This data is used to calculate relative SAPS. It is not intended to be used to project any possible benchmark results that were not actually executed (1) Ratio of Power 750 to DL380 G6 = 85222/18030 = 4.7 to 1; (2) Ratio o fDL380 G5 to DL380 G6 = 12600/25000 = .504 to 1; (3) Therefore ratio of Power 750 to DL380 G5 = 4.7/.504 = 9.3 to 1 SAP SD 2-tier Benchmark Results All results as of 5/10/10. Sources: www.tpc.org, www.sap.com/solutions/benchmark The virtualized system count and energy savings were derived from several factors: A performance factor of 7.88 was determined by SAP 2-tier SD benchmark results for the Power 750, the and the DL380 G6 and the DL380 G5 for using the DL380 G6 as a bridge since it was has results with both the old and new SAP benchmark kits and reducing the ratio based on rPerf ratio of 32-core Power 750 with 3.0GHz processor to 32-core Power 750 with 3.55GHz processor . The benchmark reviewed were current as of April 8, 2010. The benchmark detail is shown on the chart SAP Detailed Benchmark Performance. A virtualized utilization factor of 80% was assumed for the Power 750 Express and a non-virtualized utilization factor of 15% was assumed for the HP ProLiant DL380 G5. Power consumption figures of 1950 W for the IBM Power 750 Express and 1186 W for the DL380G5 and 1348 W for the DLL380 G6 were based on the maximum rates published by IBM and HP respectively. The data for the HP DL380 G5 came from the HP ProLiant DL380 G5 QuickSpecs available at http://h18004.www1.hp.com/products/quickspecs/12477_na/12477_na.html#Overview as April 8, 2010. The data for the DL380 G6 came from thre HP ProLiant DL380 G6 QuickSpecs available at http://h18004.www1.hp.com/products/quickspecs/13234_na/13234_na.html#Power%20Specifications as of April 8, 2010. Energy cost based on a Power Usage Effectiveness of 2.0 (representing an efficient datacenter). Energy cost of $.1021per kWh is based on 2009 YTD US Average Retail price to commercial customers per US DOE at http://www.eia.doe.gov/cneaf/electricity/epm/table5_6_b.html as of April 8, 2010. The reduction, if any, in floor space, power, cooling and software costs depends on the specific customer, environment, application requirements, and the consolidation potential. Actual numbers of virtualized systems supported will depend on workload levels for each replaced system. The Oracle DB Software and Subscriptions savings based on .5 licenses per core for the DL380 G5 and 1 license per core for the Power 750. The DL380 G5 & DL380 G6 DB configurations included Oracle RAC and Partitioning since multiple systems were required for the DB portion of the workload. Oracle list prices from the Oracle Store available through www.oracle.com. Prices are current as of April 8, 2010.

Non-GAAP Supplemental ATTACHMENT II

In an effort to provide investors with additional information regarding the company's financial results and other financial information as determined by generally accepted accounting principles (GAAP), the company also discusses in these materials, the following Non-GAAP information which management believes provides useful information to investors. Constant Currency Management refers to growth rates at constant currency or adjusting for currency so that the business results can be viewed without the impact of fluctuations in foreign currency exchange rates, thereby facilitating period-to-period comparisons of the company's business performance. Constant currency revenue results are calculated by translating current period revenue in local currency using the prior year's currency conversion rate. This consistent approach is based on the pricing currency for each country which is typically the functional currency. Generally, when the dollar either strengthens or weakens against other currencies, the growth at constant currency rates or adjusting for currency will be higher or lower than growth reported at actual exchange rates. Cash Flow Management includes presentations of both cash flow from operations and free cash flow that exclude the effect of Global Financing Receivables. For a financing business, increasing receivables is the basis for growth. Receivables are viewed as an investment and an income-producing asset. Therefore, management presents financing receivables as an investing activity. Management’s view is that this presentation gives the investor the best perspective of cash available for new investment or for distribution to shareholders. Non-GAAP Supplementary Materials

Operating Earnings / Operating EPS / Operating Pre-Tax Income / Operating Segment Profit Management presents certain financial results and other financial information excluding the effects of the following items: (1) acquisition-related charges and (2) certain retirement-related charges. Throughout the materials, management uses the term "operating" to describe this view of the company's financial results and other financial information. Management believes this view provides increased transparency to operational results and pension plan performance, improves visibility to management decisions and operational effects, and provides for a better comparison to peer companies. Additionally, this view allows for a long term view of the business. Non-Recurring Items Management presents certain financial results excluding the effects of the following items: (1) divestitures and (2) acquisitions. Given the non-recurring nature of these items, management believes that presenting certain financial information without these items is more representative of the company’s operational performance and provides additional insight into, and clarifies the basis for, historical and/or future performance, which may be more useful for investors.
