      BLUE VALLEY BAN CORP REPORTS ANNUAL AND FOURTH QUARTER 2006 EARNINGS

Overland Park, Kansas, January 17, 2007 -- Blue Valley Ban Corp (OTCBB: BVBC)
("the Company") today announced net income of $6.9 million or fully-diluted
earnings per share of $2.88 per share for the year ended December 31, 2006,
compared to net income of $4.6 million or $1.91 per share for the same period in
2005. Net income for the fourth quarter of 2006 was $2.1 million, or
fully-diluted earnings per share of $0.83, compared to $1.4 million, or $0.57
per share for the same period in 2005.

"2006 was a very good year for Blue Valley Ban Corp. Driven by a strong increase
in our net interest margin, our net income in 2006 increased 52% over 2005. We
expect 2007 to be another year of opportunities for our Company as we establish
our presence in Lenexa, work towards additional loan and deposit growth, and
continue to focus on operating efficiently to improve our overall financial
performance" said Robert D. Regnier, Chairman and CEO of Blue Valley Ban Corp.

During December 2006, the Company's Board of Directors declared a $0.30 per
share cash dividend on the Company's common stock. The dividend will be paid on
January 29, 2007 to shareholders of record as of December 29, 2006.

OPERATING RESULTS

For the twelve-month period ending December 31, 2006, net interest income
increased 24.4% to $27.9 million compared to $22.4 million for the same period
in the prior year, primarily due to expansion of our net interest margin
resulting from a higher yield on average earning assets. Noninterest income
decreased 21.4% to $8.9 million during this period from $11.3 million in the
prior year. The principal factor driving the decrease in non-interest income was
lower mortgage origination volume. Noninterest expense decreased 6.7% to $24.4
million compared to $26.1 million in the prior year period. The decrease relates
primarily to lower compensation costs associated with the mortgage division.

For the fourth quarter of 2006, net interest income increased 13.4% to $7.2
million compared to $6.3 million for the same period in the prior year,
primarily due to expansion of our net interest margin resulting from a higher
yield on average earning assets. Noninterest income decreased to $2.3 million
during this period from $2.5 million in the prior year, a decrease of 6.1% due
primarily to lower mortgage origination volume. Noninterest expense decreased
7.0% to $6.1 million compared to $6.6 million in the prior year period. This
decrease in noninterest expense relates primarily to lower compensation costs
associated with the mortgage division.

Total assets, loans and deposits at December 31, 2006 were $692.2 million,
$528.5 million and $535.9 million, respectively, compared to $689.6 million,
$503.1 million and $529.3 million one year earlier, respectively, increases of
0.4%, 5.0% and 1.2%, respectively.
