    Stan Galanski, Navigators' Chief Executive Officer, commented, "We
are pleased with the strong underwriting results for the second
quarter. Our record quarterly net income reflects our culture of
underwriting discipline, favorable loss development, growth in
investment income and the ongoing execution of our strategy. We are
encouraged that incurred loss activity remains well within our
expectations and that our loss reserves have never been stronger.
Despite increasingly challenging market conditions, we continue to
deliver shareholder value by capitalizing on growth opportunities in a
number of product lines and geographic niches. At the same time, our
underwriters continue to refrain from writing business that fails to
meet our underwriting standards."

    Net investment income for the 2007 second quarter and six month
period was $17,330,000 and $33,546,000, respectively, increases of 24%
