VULCAN MATERIALS COMPLETES ACQUISITION OF FLORIDA ROCK

Birmingham, AL, November 16, 2007 — Vulcan Materials Company (NYSE: VMC) today announced the completion of its acquisition of Florida Rock Industries, Inc. (NYSE: FRK), a leading producer of construction aggregates, cement, concrete and concrete products in the Southeast and Mid-Atlantic states, for total consideration to Florida Rock shareholders of approximately $4.2 billion based on the closing price of Vulcan stock on November 15, 2007.

The acquisition further diversifies the geographic scope of Vulcan’s operations, providing the Company with an enhanced presence in attractive Florida markets and in other high-growth Southeast and Mid-Atlantic states while also bringing Vulcan more than 2 billion tons of aggregates reserves in markets where reserves are increasingly scarce.

“We are very pleased to announce the closing of our acquisition of Florida Rock. We can now begin pursuing the synergies from our combination and opportunities from our broadened regional footprint and expanded presence in some of the most attractive construction materials markets in the U.S. The addition of Florida Rock will enhance our strategic position and long-term growth opportunities,” said Vulcan’s Chairman and CEO, Don James. “We are particularly pleased to welcome Florida Rock — a company we have respected for many years and know to share our values and management philosophy — into the Vulcan family. We look forward to our collaboration and entering the next chapter of our history together.”

Florida Rock President and CEO, John Baker said “We are extremely pleased to have completed the combination of our organization with Vulcan Materials. We have great respect for Vulcan Materials’ team and believe they offer an ideal business fit and a highly compatible culture to Florida Rock’s. This is good for our shareholders as well as our employees who will enjoy enhanced opportunities as part of an even stronger and more geographically diversified organization that has operations in key high-growth markets nationwide.”

Under the terms of the agreement announced on February 19, 2007, Vulcan Materials Company stockholders are to receive one share of common stock in a new holding company (whose subsidiaries will be Vulcan Materials Company and Florida Rock) for each Vulcan Materials Company share.

Former Florida Rock stockholders will receive either 0.63 shares of the new holding company or $67.00 in cash, without interest, for each Florida Rock share, subject to proration, to ensure that in the aggregate 70% of Florida Rock shares will be converted into cash and 30% of Florida Rock shares will be converted into stock. The pro rata allocation of cash and stock payable to the electing holders will be announced following receipt of the final election results, which are expected to be available on or about November 21, 2007. In connection with the completion of the transaction, Florida Rock’s shares will no longer be traded on the NYSE.

Further details about the transaction are available on the web at www.vulcanfloridarock.com.

In addition, the quarterly dividend of 46 cents per share announced by Vulcan on October 16, 2007 will be payable December 10, 2007 to shareholders of record on November 26, 2007 of the new holding company’s common stock.
