Ambition level of combined pre-tax profit for PBC / Postbank at EUR > 3 bn EUR 1 bn of targeted run-rate synergies p.a. identified so far Targeted restructuring cost of EUR 1.4 bn Intent to consolidate triggers a EUR (2.4) bn revaluation of current stake and mandatory exchangeable through P&L in 3Q2010 On balance, our assumptions(1) still support EUR 10 bn pre-tax profit target for 2011(2); from today's perspective, the acquisition does not change this target Financial impact: Key data Based on 2Q2010 and methodology explained on page 15 Profitability Tier 1 capital ratio post capital increase and acquisition expected to be at 11.6% (core Tier 1 ratio at 8.0%)(3), before 2H2010 retained earnings(4) Medium-term Tier 1 capital relief potential from divestments, further de-risking at Deutsche Bank and run-off of non-customer assets at Postbank Maintain our Tier 1 ratio target of at least 10%, subject to adjustment once new capital regime in place Capital Adding EUR 93 bn to create combined retail deposit base of EUR ~260(5) bn Funding Some environmental variables are in line with or ahead of our assumptions, others have not yet reached the expected levels, particularly with respect to the normalization of interest rates From core businesses, excluding Corporate Investments and Consolidation & Adjustments Assumes 21% take-up and is based on methodology explained on page 15 EUR (2.4) bn revaluation impact of current stake and mandatory exchangeable in 3Q2010 is already reflected in expected capital ratios Includes EUR 50 bn from Deutsche Bank Private Wealth Management and excludes business clients

Rationale for transactions Aim to accelerate integration, optimize acquisition cost, support balance sheet restructuring Use time window, thus pass 30% threshold and qualify as voluntary public tender offer (PTO) with releasing effect Optimize value for shareholders by reducing total acquisition costs by up to EUR 1.7 bn Aim for early consolidation, potentially in 4Q2010 Why do public tender offer now? Aspire to accelerate integration process to maximize shareholder return Aim to realize synergy potential and take full advantage of growth opportunities Why consolidate now? Mainly to cover capital consumption from Postbank consolidation, and to support capital base Maintain prudent capital management while allowing for capital relief from run-off in Postbank non-core portfolio Why ~9.5 billion net new capital?

Methodology for Tier 1 capital impact assessment Calculated with the fully underwritten subscription price of EUR 31.80 for 308.64 m shares, which equals EUR 9.8 bn of gross proceeds; net proceeds of EUR 9.5 bn reflect dividend accrual assumption of EUR 0.75 per new share for 1H2010 and transaction fees Capital increase impact Assumes take-up of 21% in public tender offer (PTO) PTO take-up Basis: Fair value (FV) disclosure of Postbank per 30 June 2010 (outside-in view); adjustments only for known methodological differences, especially application of liquidity spreads for Postbank's loans and receivables Final calculation of FVs for purchase price allocation can only be determined at the time of full consolidation; the amounts can significantly differ from those of the outside-in view, mainly due to market movements until full consolidation (especially interest rates, liquidity spreads) and application of Deutsche Bank's FV methods and policies after access to Postbank's books and records Valuation / purchase price allocation Tier 1 impact from full consolidation benefits from reversal of EUR 2.4 bn Tier 1 capital consumption from current investment in Postbank IFRS 3 loss Reversal of current Tier 1 impact Under current IFRS 3 rule(1), the documented intention to consolidate triggers revaluation of existing equity interest (including mandatory exchangeable) at Fair Value (FV) through P&L; expected future cash flows have not deteriorated Revaluation takes into account cumulative equity pick-ups and is based on an assumed FV of EUR 24.42 of Postbank share; if DB decides to fully consolidate before publication of 3Q2010 results, the IFRS 3 loss will already have to be recorded in 3Q2010 Postbank RWAs, including market risk, supported with 10% target Tier 1 ratio of Deutsche Bank RWA Under previous IFRS 3 rule (until 2009), instead of a revaluation loss via P&L, the goodwill would have been higher, i.e. no material difference in Tier 1 capital impact

This presentation contains forward-looking statements. Forward-looking statements are statements that are not historical facts; they include statements about our beliefs and expectations and the assumptions underlying them. These statements are based on plans, estimates and projections as they are currently available to the management of Deutsche Bank. Forward-looking statements therefore speak only as of the date they are made, and we undertake no obligation to update publicly any of them in light of new information or future events. By their very nature, forward-looking statements involve risks and uncertainties. A number of important factors could therefore cause actual results to differ materially from those contained in any forward-looking statement. Such factors include the conditions in the financial markets in Germany, in Europe, in the United States and elsewhere from which we derive a substantial portion of our revenues and in which we hold a substantial portion of our assets, the development of asset prices and market volatility, potential defaults of borrowers or trading counterparties, the implementation of our strategic initiatives, the reliability of our risk management policies, procedures and methods, and other risks referenced in our filings with the U.S. Securities and Exchange Commission (SEC). Such factors are described in detail in our SEC Form 20-F of 16 March 2010 under the heading "Risk Factors." Additional factors relating to the takeover offer and related transactions referred to in this presentation include the unavailability of internal Postbank information to Deutsche Bank, limits on Deutsche Bank's ability to achieve the benefits or synergies it expects or to avoid higher costs for integration and the combined business, the effect of the transaction on Deutsche Bank's core capital and other risks referenced under the headings "Risk Factors" in the prospectus dated 29 September 2009, as it will be supplemented by the prospectus supplement expected to be filed with the SEC on or about 21 September 2010. Copies of this document are readily available upon request or can be downloaded from www.sec.gov. In addition, this presentation contains financial and other information which has been derived from publicly available information disclosed by persons other than Deutsche Bank ("external data").

Commercial publications generally state that the information they contain has originated from sources assumed to be reliable, but that the accuracy and completeness of such information is not guaranteed and that the calculations contained therein are based on a series of assumptions. The external data has not been independently verified by the Company. Therefore, the Company cannot assume any responsibility for the accuracy of the external data taken or derived from public sources.
