Legal and Administrative Proceedings

The Corporation is engaged in certain legal and administrative proceedings incidental to its normal business activities. In the opinion of management and counsel, based upon currently-available facts, it is remote that the ultimate outcome of any litigation and other proceedings, including those pertaining to environmental matters, relating to the Corporation and its subsidiaries, will have a material adverse effect on the overall results of the Corporation’s operations, its cash flows or its financial position.

On May 4, 2012, the Court of Chancery of the State of Delaware issued an opinion and on May 14, 2012, it entered a final order and judgment pursuant to which, among other things, the Corporation was enjoined for a period of four months from prosecuting a proxy contest, making an exchange or tender offer, or otherwise taking steps to acquire control of Vulcan Materials Company (“Vulcan”) shares or assets. In accordance with this order, the Corporation terminated its exchange offer for Vulcan shares and its proxy solicitation to elect four nominees to the board of directors of Vulcan. The Delaware Supreme Court affirmed the Court of Chancery decision on May 31, 2012.

Environmental and Governmental Regulations

In 2010, the United States Environmental Protection Agency (“USEPA”) included the lime industry as a national enforcement priority under the federal Clean Air Act (“CAA”). As part of the industry wide effort, the USEPA issued Notices of Violation/Findings of Violation (“NOVs”) to the Corporation in 2010 and 2011 regarding the Corporation’s compliance with the CAA New Source Review (“NSR”) program at its Specialty Products dolomitic lime manufacturing plant in Woodville, Ohio. The Corporation has been providing information to the USEPA in response to these NOVs and has had several meetings with the USEPA. The Corporation believes it is in substantial compliance with the NSR program. Because the enforcement proceeding is in its initial stage, at this time the Corporation cannot reasonably estimate what reasonable likely penalties or required upgrades to equipment might ultimately be required. The Corporation believes that any costs related to any required upgrades will be spread over time and will not have a material adverse effect on the Corporation’s operations or its financial condition, but can give no assurance that the ultimate resolution of this matter will not have a material adverse effect on the financial condition or results of operations of the Specialty Products segment of the business.

Guarantee of Affiliate

The Corporation has an unconditional guaranty of payment agreement with Fifth Third Bank (“Fifth Third”) to guarantee the repayment of amounts borrowed by an affiliate under a $24,000,000 revolving line of credit provided by Fifth Third that expires in July 2013 and a guaranty agreement with Bank of America, N.A., to guarantee a $6,200,000 amortizing loan due April 2016. The affiliate has agreed to reimburse and indemnify the Corporation for any payments and expenses the Corporation may incur from these agreements. The Corporation holds a subordinate lien of the affiliate’s assets as collateral for potential payments under the agreements.
