'It's a blockbuster of a transaction,' said Denis Laplante of Keefe, Bruyette & Woods. The merged bank will control 7% to 8% of deposits in the US, below the 10% allowed.Harrison will be chairman and chief executive. Bank One's Jamie Dimon will be president and chief operating officer, succeeding Harrison in 2006.Laplante said: 'JP Morgan gets diversification out of capital markets into retail banking and Dimon gets to run the combined company with the brokerage capability he was coveting.'MORE ABOUTBankingCitigroupInvestmentJp Morgan ChaseNYSENYSE Euronext
