                    American Medical Security Announces Sale
                     Of Its Accountable Health Plan Network


         GREEN BAY, Wis. - September 10, 2003 -- American Medical Security
Group, Inc. (NYSE:AMZ)(AMS) and IPACQ, Inc. have concluded an agreement for
the sale of AMS' subsidiary, Accountable Health Plans of America, Inc.
(AHP), to IPACQ.

         Under terms of the agreement, IPACQ has purchased all outstanding
common shares of AHP held by American Medical Security Holdings, Inc. for
approximately $3.5 million in cash. As a result of the sale, AMS will report a
one-time net gain from discontinued operations of approximately $0.05 per share
in the third quarter of 2003.

         AHP is a PPO (preferred provider organization) network located in
Arlington, Tex. The network contracts with more than 900 hospitals, and 100,000
physicians in eight primary states: Arizona, Florida, Iowa, Nebraska, North
Dakota, South Dakota, Texas and Wisconsin.

         "AHP is no longer a strategic fit for our company," said Samuel V.
Miller, AMS Chairman, President & Chief Executive Officer. "It's important that
we focus our long-term strategies on our core businesses while transitioning AHP
to an owner whose business is managing PPO networks."
