                                                          For Immediate Release


         MARIETTA, Pennsylvania, September 4, 2003 - Donegal Group Inc. (Nasdaq
DGICA and DGICB) today reported that it had agreed to acquire all of the
outstanding capital stock of an affiliated company, Le Mars Mutual Insurance
Company of Iowa, following the conversion of Le Mars to a stock insurance
company. The conversion, which is subject to approval by the policyholders of Le
Mars and the Insurance Commissioner of the State of Iowa, is expected to be
completed by the end of 2003. DGI will acquire the stock of Le Mars for $8.2
million. DGI also expects to make an additional capital contribution to Le Mars
of approximately $4.0 million.

         Le Mars operates as a multiple line carrier in Iowa, Nebraska, Oklahoma
and South Dakota. Personal lines coverages represent a majority of premiums
written, with the balance coming from farmowners and mercantile and service
businesses. Le Mars' largest line of business is private passenger automobile
liability and physical damage; other principal lines include homeowners and
commercial multi-peril. On a statutory basis as of July 31, 2003, Le Mars had
total admitted assets of $37.3 million, and policyholders' surplus (exclusive of
a $4.0 million surplus note held by DGI) of $7.2 million. For the year ended
December 31, 2002 and the seven months ended July 31, 2003 on a statutory basis,
Le Mars had earned premiums of $21.0 million and $10.3 million, respectively.
Since June 2002, the Donegal Insurance Group has been assisting Le Mars in the
restructuring of its insurance business for the purpose of restoring Le Mars'
underwriting profitability.

"We look forward to completion of the Le Mars acquisition as the first step in the expansion of our operations to the mid-West," stated Donald H. Nikolaus, President and Chief Executive Officer of Donegal Group. Donegal Group Inc. is a regional property-casualty insurance holding company currently doing business in 14 Mid-Atlantic and Southern states through its insurance subsidiaries, Atlantic States Insurance Company and Southern Insurance Company of Virginia.
