LONDON, Aug 5 (Reuters) - BP on Tuesday posted a

second-quarter underlying replacement cost profit, or adjusted

net income, of $2.4 billion, down 14% from last year's $2.8

billion, but easily beating the average $1.8 billion in a

company-provided poll of analysts.

Its quarterly dividend will rise to 8.32 cents from 8 cents

and it will keep the pace of its share buyback programme at $750

million for the second quarter, it said.
