                              SOUTHFIELD, MICHIGAN
                                 APRIL 19, 2005


Meadowbrook Insurance Group, Inc. (NYSE: MIG) announced today that the ratings
of certain of its insurance company subsidiaries have been upgraded by rating
agency A.M. Best Company to "B++" (Very Good). The upgrade reflects A.M. Best's
positive assessment of Meadowbrook's financial condition as a result of the
Company's continued underwriting and operating improvements through 2004, the
group's solid capitalization and management's knowledge and expertise in the
alternative risk market.


The rating applies to three of Meadowbrook's insurance company subsidiaries:
Star Insurance Company, Savers Property & Casualty Insurance Company, and
Williamsburg National Insurance Company. Additionally, A.M. Best reaffirmed the
rating of the Company's other insurance company subsidiary, Ameritrust Insurance
Corporation, as "B+", with a positive outlook.


In its news release, A.M. Best noted: "The rating also recognizes the
significant improvement in 2004 earnings, Meadowbrook's earnings prospects in
2005 and diminished reserve development reported from prior years."


"We are very pleased with A.M. Best's decision to upgrade these ratings," said
Robert S. Cubbin, President and Chief Executive Officer of Meadowbrook Insurance
Group. "We anticipate that this news will be positively received by the
marketplace and will allow us to continue to retain and attract quality
business."
