                     AMERICAN PHYSICIANS SERVICE GROUP, INC.
                ANNOUNCES INCREASE IN REVENUES, OPERATING INCOME


     AUSTIN,  TEXAS,  May 11, 2006 - American  Physicians  Service  Group,  Inc.
("APS")  (NASDAQ:  AMPH) today announced  results for the first quarter of 2006.
For the three months ended March 31, 2006,  revenues were $7,233,000 compared to
$6,662,000  a year-ago.  Operating  income was $676,000  versus  $577,000 a year
earlier,  while net income of $562,000 compares to net income of $853,000 in the
same quarter of 2005. In 2005,  gains on sales of investments had added $591,000
to pretax income versus $7,000 in the current period. Diluted earnings per share
in the current  quarter  were $0.19  compared  to $0.30 in the first  quarter of
2005.

     Ken Shifrin,  APS Chairman of the Board,  stated, "We are very pleased with
first quarter  results.  Revenues  were up 9% and  operating  income was up 17%,
compared to the same quarter last year. Net income had been positively  impacted
in the quarter ended March 31, 2005 by a large,  one-time,  investment gain that
we did not have in the quarter just ended, but our core businesses  continued to
perform well."

     Mr.  Shifrin  continued,  "Our  insurance  segment  beefed up its marketing
effort last year and has increased the number of insured doctors for its managed
insurance  company by about 12% since March 31,  2005.  Our  financial  services
segment  benefited  from its entry last year into  investment  banking and trade
claims clearing,  boosting revenue  quarter-to-quarter in what was a challenging
market for its core fixed-income  business.  We are proud of the resourcefulness
that our management team has shown."



     Mr. Shifrin  concluded,  "Attention to shareholder value continues to be an
integral part of our business plan. Book value per share was $10.16 per share at
March 31, 2006  compared to $9.32 at March 31,  2005.  A year before that it was
$8.18, a trend  reflective of our excellent  earnings and our  consistent  stock
repurchases.  Our balance sheet continues to give us stability and  opportunity,
with outstanding working capital, liquidity, and no debt."
