                     AMERICAN PHYSICIANS SERVICE GROUP, INC.
                   REPORTS 92% EPS INCREASE IN SECOND QUARTER 

     AUSTIN,  TEXAS,  August 8, 2005 - American  Physicians  Service Group, Inc.
("APS")  (NASDAQ:  AMPH) today announced  results for the quarter and six months
ended June 30, 2005.  For the three months  ended June 30, 2005,  revenues  were
$7,033,000  compared to $7,295,000 for the three months ended June 30, 2004. Net
earnings  were  $1,367,000  or $.48 per share,  compared to $689,000 or $.25 per
diluted share for the three months ended June 30, 2004. For the six months ended
June 30, 2005,  revenues were  $13,695,000  compared to $14,585,000  for the six
months ended June 30, 2004.  Net earnings  were  $2,220,000  or $.77 per diluted
share, compared to $1,383,000 or $.49 per diluted share for the six months ended
June 30, 2004.

     Ken Shifrin,  APS Chairman of the Board stated, "We are pleased that, taken
together,  operating income at our two core business segments exceeded operating
income in the comparable  quarter a year-ago.  The increase was approximately 7%
on  approximately  9% lower  revenues.  On an  individual  basis,  our insurance
services segment continued its positive trend, while interest rate and inflation
concerns kept our financial services segment underperforming last year."

     Mr. Shifrin  continued,  "As in the first quarter,  we were able to realize
gains  this  quarter on equity  investments,  recognizing  $1,289,000  in pretax
income. Partially offsetting the gain were expenses related to the sale that are



included in general and administrative expenses.  Proceeds of the sale have been
invested  primarily in government  securities,  with a portion set aside to fund
our recently announced dividend.

     Mr. Shifrin concluded,  "Along with operating performance we remain focused
on value and  liquidity.  Book value per share as of the June 30,  2005  balance
sheet increased to $9.62 from $8.23 per share at June 30, 2004.  Contributing to
the book value improvement has been our management of shares outstanding. At our
Annual  Meeting,  shareholders  approved  new  equity  compensation  plans  that
continue to align  managements' and  shareholders'  interests,  while minimizing
share  dilution.  We also remain active with our share  repurchase plan and have
now invested  approximately  $1.4 million of the $2.0 million  authorized by our
board of directors.  With a current ratio exceeding 5:1, our liquidity has never
been better and we remain  alert to  opportunities  that have the  potential  to
increase shareholder value."
