JAMES MONROE BANCORP REPORTS FIRST QUARTER 2006 EARNINGS...

ARLINGTON, VA, (BUSINESS WIRE)--April 19, 2006.--James Monroe Bancorp, Inc.
(Nasdaq Capital Market: JMBI - news) today announced earnings for the first
quarter of 2006. Net income was $967,000 or $.17 per diluted share, compared to
net income of $768,000, or $.13 per diluted share for the first quarter of 2005,
an increase of 25.9% in net income and an increase of 29.6% in earnings per
diluted share over the previous year quarter. Book value per share at March 31,
2006 was $7.36 compared to $6.52 at the end of first quarter 2005. On March
27th, the Board of Directors of James Monroe Bancorp, Inc. announced its
agreement to merge with Mercantile Bankshares Corporation.

The per share calculations, weighted average diluted shares outstanding and the
book value per share, on a comparative basis to prior periods, have been
affected by the exercise of stock options late in the first quarter of 2006. The
exercise of options did not have a material effect on earnings per share or book
value per share.

Total assets at March 31, 2006 were $544.9 million, a 17.3% increase over assets
of $464.6 million at March 31, 2005. Also, total deposits at the end of March
increased 8.4% to $452.7 million compared to the end of March a year ago. Loans
outstanding increased 36.6% over first quarter 2005 to $398.2 million. Return on
average assets was .74% for the first quarter of 2006 compared to .70% for the
first quarter of 2005.

James Monroe Bancorp's President and Chief Executive Officer, John R. Maxwell,
commented, "We are pleased to report excellent growth since the first quarter of
last year. Loans increased 36.6% from a year ago in an environment of increasing
competition for high quality loans. With this growth, we continue to maintain
the same high level of loan quality. We had no loan charge offs during the first
quarter and our nonperforming loans declined again this quarter from $315,000 to
$241,000. Generating deposit growth, while also maintaining a strong net
interest margin, continues to be the challenge faced by all the banks in our
market. Our net interest margin decreased from first quarter last year from
3.82% first quarter 2005 to 3.69% in the first quarter 2006.

"Our results for the first quarter are consistent with our financial plan for
2006," David Pijor, Chairman of James Monroe Bancorp stated. "We are very
excited about the upcoming merger with Mercantile Bankshares. We share the same
philosophies and approach to serving our customers. Our customers will continue
to see the same level of superior customer service. In addition, Mercantile will
bring new services and products, providing additional benefits for our
customers."

not recognized under generally accepted accounting principles, but which we
believe provides investors with important information regarding our operational
efficiency. Comparison of our efficiency ratio with those of other companies may
not be possible because other companies may calculate the efficiency ratio
differently. The Company, in referring to its net income, is referring to income
under generally accepted accounting principles, or "GAAP".
