2Q YTD Cash Flow Summary

Forward Looking Statements 4 Our presentation contains "forward-looking" statements or projections based on current expectations. These statements are not guarantees of future performance and are subject to risks and uncertainties. Actual results may differ materially due to: the availability of government funding and budgetary constraints; changes in customer priorities; the impact of economic recovery and stimulus plans and continued hostilities in Iraq and Afghanistan on funding for defense programs; program and contract performance; return or loss on benefit plan assets, interest and discount rates, and other changes that may affect benefit plan assumptions; the effect of capitalization changes (such as share repurchase activity, advance pension funding, option exercises, or debt levels) on earnings per share; failure to have key programs recertified after notice of exceeding cost-growth thresholds specified by the Nunn- McCurdy process; the timing and availability of future government awards; the outcome of legal proceedings; the future impact of acquisitions, divestitures or joint ventures, including the potential that a delay in the divestiture of EIG could result in U.S. Government customers electing not to renew existing or award new contracts to EIG; the timing and availability of future government awards;; economic, business and regulatory conditions and other factors. We disclaim any duty to update forward-looking statements to reflect new developments. Our SEC filings (found at www.lockheedmartin.com or at www.sec.gov), including our 2009 Form 10-K and 2010 10-Q, contain more information on the types of risks and other factors that could adversely affect these statements. 2010 Financial Results are Unaudited Chart 2 July 27, 2010
