Management's Discussion and Analysis of Financial Condition and Results of Operations Overview Donegal Group Inc. ("DGI" or the "Company") is a regional insurance holding company doing business in Pennsylvania, Maryland, Delaware, Virginia and Ohio through its four wholly owned property-casualty insurance subsidiaries, Atlantic States Insurance Company ("Atlantic"), Southern Insurance Company of Virginia ("Southern"), Pioneer Insurance Company ("Pioneer") and Delaware Atlantic Insurance Company ("Delaware"). The Company's major lines of business in 1996 and their percentage of total net earned premiums were Automobile Liability (27.7%), Workers' Compensation (18.0%), Automobile Physical Damage (16.0%), Homeowners (16.6%), and Commercial Multiple Peril (16.0%). The subsidiaries are subject to regulation by Insurance Departments in those states in which they operate and undergo periodic examination by those departments. The subsidiaries are also subject to competition from other insurance carriers in their operating areas. DGI was formed in September 1986 by Donegal Mutual Insurance Company (the "Mutual Company"), which owns 59% of the outstanding common shares of the Company as of March 31, 1997. Atlantic States participates in an intercompany pooling arrangement with the Mutual Company and assumes 65% of the pooled business, 60% prior to January 1, 1996. Southern cedes 50% of its business to the Mutual Company and Delaware cedes 70% of its Workers' Compensation business to the Mutual Company. Because the Mutual Company places substantially all of the business assumed from Southern and Delaware into the pool, from which the Company has a 60% allocation, the Company's results of operations include approximately 80% of the business written by Southern and approximately 70% of the Workers' Compensation business written by Delaware. On March 31, 1997, the Company acquired all of the outstanding stock of Pioneer Insurance Company. This transaction was accounted for as if it were a "Pooling of interest," and as such, the Company's financial statements have been restated to include Pioneer as a consolidated subsidiary from January 1, 1994 to the present. In January 1994, the Company organized a new subsidiary, Atlantic Insurance Services, Inc. ("AIS"), which began business in that same month. AIS is an insurance services organization currently providing inspection and policy auditing information on a fee for service basis to its affiliates and the insurance industry. -5-

DONEGAL GROUP INC. AND SUBSIDIARIES (Unaudited) Summary Notes to Consolidated Financial Statements 1 - Organization The Company was organized as a regional insurance holding company by Donegal Mutual Insurance Company (the "Mutual Company") on August 26, 1986 and operates in Pennsylvania, Maryland, Delaware, Virginia and Ohio through its wholly owned stock insurance companies, Atlantic States Insurance Company ("Atlantic States"), Southern Insurance Company of Virginia ("Southern"), Delaware Atlantic Insurance Company ("Delaware"), Pioneer Insurance Company ("Pioneer") and Atlantic Insurance Services, Inc. ("AIS"). The Company's major lines of business are Automobile Liability, Automobile Physical Damage, Homeowners, Commercial Multiple Peril and Workers' Compensation. Atlantic, Southern and Delaware are subject to regulation by Insurance Departments in those states in which they operate and undergo periodic examination by those departments. They are also subject to competition from other insurance carriers in their operating areas. Atlantic States engages in the insurance business primarily through an intercompany pooling arrangement with the Mutual Company. Southern was acquired by the Company on December 31, 1988 pursuant to a plan of conversion from a mutual to a stock company and cedes 50% of its business to the Mutual Company, 80% prior to 1991. On December 29, 1995, the Company acquired all of the outstanding stock of Delaware. This transaction was accounted for as if it were a "Pooling of interest," and as such, the Company's financial statements have been restated to include Delaware as a consolidated subsidiary from January 1, 1994 to the present. On March 31, 1997, the Company acquired all of the outstanding stock of Pioneer. This transaction was accounted for as if it were a "Pooling of Interest", and as such the Company's financial statements have been restated to include Pioneer as a consolidated subsidiary from January 1, 1994 to the present. At March 31, 1997 the Mutual Company held 59% of the outstanding common stock of the Company. 2 - Basis of Presentation The financial information for the interim period included herein is unaudited; however, such information reflects all adjustments, consisting only of normal recurring adjustments, which, in the opinion of management of Registrant, are necessary to a fair presentation of Registrant's financial position, results of operations and changes in financial position for the interim period included herein. The results of operations for the three months ended March 31, 1997, are not necessarily indicative of results of operations to be expected for the twelve months ended December 31, 1996. These financial statements should be read in conjunction with the financial statements and notes thereto contained in the Registrant's Annual Report on Form 10-K for the year ended December 31, 1996. -6-

Results of Operations - Three Months Ended March 31, 1997 to Three Months Ended March 31, 1996 Revenues for the three months ended March 31, 1997 were $29,823,371, an increase of $645,430 or 2.2%, over the same period of 1996. An increase in net premiums earned of $568,838 or 2.2%, represented most of this change. Investment income for the first quarter of 1997 was $2,844,983, an increase of $124,776 or 4.6%, over the first quarter of 1996. An increase in the average invested assets of $12,493,859 or 6.9%, to $192,924,668 and a decrease in the average return on investments to an annualized rate of 5.9% for the first quarter of 1997 compared to 6.0% for the first quarter of 1996, accounted for the change. Realized investment gains, which resulted from the normal turnover of the Company's investment portfolio, decreased $224,247 for the three months ended March 31, 1997 compared to the same period in 1996, to $37,827. The GAAP combined ratio of insurance operations in the first quarter of 1997 was 98.2% compared to 104.8% for the same period in 1996. The GAAP combined ratio is the sum of the ratios of incurred losses and loss adjusting expenses to premiums earned (loss ratio), policyholders dividends to premiums earned (dividend ratio), and underwriting expenses to premiums earned (expense ratio). The Company posted a loss ratio of 56.7% for the first quarter 1997 compared to the 72.4% loss ratio it posted for the first quarter 1996. Dramatically improved weather conditions in 1997 compared to the severe and unusual weather that was experienced in early 1996 accounted for the improvement. The expense ratio increased from 31.1% to 32.5% for the three months ended March 31, 1997 due primarily to increases in incentive expenses for employees and agents related to the lower claims activity for the first quarter. The dividend ratio increased slightly from 1.3% for the first quarter of 1996 to 1.6% for the first quarter of 1997, due primarily to higher levels of profitability in the workers' compensation line. Federal income taxes for the first quarter of 1997 represented 22.9% of income before income taxes, compared to 16.6% for the same period of 1996. Larger underwriting profits in 1997 representing a larger portion of overall income than in 1996 accounted for the increase. -7-

Liquidity and Capital Resources The Company generates sufficient funds from its operations and maintains a high degree of liquidity in its investment portfolio. The primary source of funds to meet the demands of claim settlements and operating expenses are premium collections, investment earnings and maturing investments. As of March 31, 1997, the Company had no material commitment for capital expenditures. In investing funds made available from operations, the Company maintains securities maturities consistent with its projected cash needs for the payment of claims and expenses. The Company maintains a portion of its investment portfolio in relatively short-term and highly liquid assets to ensure the availability of funds. As of March 31, 1997, pursuant to a credit agreement dated December 29, 1995, with Fleet National Bank of Connecticut, the Company had unsecured borrowings of $8.5 million. Per the terms of the credit agreement, the Company may borrow up to $20 million at interest rates equal to the bank's then current prime rate or the then current London interbank Eurodollar bank rate plus 1.70%. At March 31, 1997, the interest rate on the outstanding balance was 7.325%. In addition, the Company will pay a non-use fee at a rate of 3/10 of 1% per annum on the average daily unused portion of the Bank's commitment. On each December 29, commencing December 29, 1998, the credit line will be reduced by $4 million. Any outstanding loan in excess of the remaining credit line, after such reduction, will then be payable. The Company's principal source of cash with which to pay stockholder dividends is dividends from Atlantic States, Southern, Pioneer and Delaware, which are required by law to maintain certain minimum surplus on a statutory basis and are subject to regulations under which payment of dividends from statutory surplus is restricted and may require prior approval of their domiciliary insurance regulatory authorities. Atlantic States, Southern, Pioneer and Delaware are subject to Risk Based Capital (RBC) requirements effective for 1994. At December 31, 1996, all four Companies' capital was substantially above the RBC requirements. At December 31, 1996, amounts available for distribution as dividends to Donegal Group without prior approval of the insurance regulatory authorities are $5,410,536 from Atlantic States, $255,480 from Southern, $48,582 from Pioneer and $1,120,952 from Delaware. -8-

Credit Risk The company provides property and liability coverages through its subsidiaries' independent agency systems located throughout its operating area. The majority of this business is billed directly to the insured although a portion of Donegal Group's commercial business is billed through its agents who are extended credit in the normal course of business. The Company's subsidiaries have reinsurance agreements in place with the Mutual Company and with a number of other major authorized reinsurers. Impact of Inflation Property and casualty insurance premiums are established before the amount of losses and loss settlement expenses, or the extent to which inflation may impact such expenses, are known. Consequently, the Company attempts, in establishing rates, to anticipate the potential impact of inflation. Impact of New Accounting Standards Stock-Based Compensation Stock-based compensation plans are accounted for under the provisions of Accounting Principles Board (APB) Opinion No. 25. "Accounting for Stock Issued to Employees," and related interpretations. As such, compensation expense would be recorded on the date of a stock option grant only if the current market price of the underlying stock exceeded the exercise price. Statement of Financial Accounting Standards (SFAS) No. 123, "Accounting for Stock-based Compensation" was effective for 1996 and permits entities to recognize as expense, over the vesting period, the fair value of all stock-based awards on the date of the grant. Alternatively, SFAS No. 123 allows entities to continue to apply the provisions of APB Opinion No. 25 and provide pro forma net income and earnings per share disclosures for employee stock option grants made in 1995 and 1997 as if the fair-value-based method defined in SFAS No. 123 had been applied. The Company has elected to continue to apply the provisions of APB Opinion No. 25 and provide the pro forma disclosures under SFAS No. 123. Impairment of Long-Lived Assets The Company has adopted Statement of Financial Accounting Standards No. 121, "Accounting for the Impairment of Long-Lived Assets and Long-Lived Assets to be Disposed Of" (SFAS No. 121) effective January 1, 1996, SFAS No. 121 provides guidance for recognition and measurement of impairment long-lived assets, certain identifiable intangibles and goodwill related both to assets to be held and used and assets to be disposed of. SFAS No. 121 requires that long-lived assets and certain identifiable intangibles to be held and used by an entity be reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. In performing the review for recoverability, an entity should estimate the future cash flows expected to result from the use of the asset and its eventual disposition. If the sum of the expected future cash flows (undiscounted and without interest charges) is less than the carrying amount of the asset, an impairment loss is not recognized. Measurement of an impairment loss for long-lived assets and identifiable intangibles that an entity expects to hold and use should be based on the fair value of the asset. SFAS No. 121 requires that long-lived assets and certain identifiable intangibles to be disposed of be reported at the lower of carrying amount or fair value less cost to sell. Management believes the adoption of SFAS No. 121 has no material effect on its financial condition or results of operation. -9-
