These consolidated financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We conducted our audits in accordance with generally accepted audit standards. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the consolidated financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall consolidated financial statement presentation. We believe our audits of the consolidated financial statements provide a reasonable basis for our opinion. In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the consolidated financial position of Meadow Valley Corporation and Subsidiaries as of December 31, 1995 and 1996, and the consolidated results of their operations, and cash flows for the period from the date of inception, September 15, 1994, through December 31, 1994 and for the years ended December 31, 1995 and 1996, in conformity with generally accepted accounting principles. /s/ BDO Seidman, LLP Los Angeles, California February 28, 1997
