Shaw Urges Shareholders to Vote on Merger Agreement with CB&I

  Shaw Urges Shareholders to Vote on Merger Agreement with CB&I

Business Wire

BATON ROUGE, La. -- December 18, 2012

The Shaw Group Inc. (NYSE: SHAW) today urged its shareholders to vote on the
definitive merger agreement with CB&I (NYSE: CBI) to acquire Shaw. Shaw’s
shareholders of record at the close of business Nov. 30, 2012, will be able to
vote on the merger proposal.

As previously announced, Shaw shareholders will receive approximately $46 per
share in cash and stock ($41 in cash and .12883 shares of CB&I common stock).
This represents a 72 percent premium to the price of Shaw shares ($26.69) at
the close on July 27, 2012, the last trading day before the merger agreement
was announced.

“Shaw’s board of directors believes this merger agreement provides the best
value to all Shaw shareholders and recommends shareholders vote FOR the
proposal to adopt the merger agreement,” said J.M. Bernhard Jr., Shaw’s
chairman, president and chief executive officer. “With the special meeting of
shareholders quickly approaching, Shaw encourages all of its shareholders who
have not yet voted to immediately vote each and every proxy card received.”

Shareholders may receive more than one proxy card. It is very important to
vote each and every proxy card received as each of these cards has a unique
control number that is tied to differing accounts holding shares. Shareholders
still receiving proxy cards mean shares remain to be voted. Shareholders
should be aware that not voting will have the same effect as a vote against
the merger proposal.

Shaw cannot complete the merger and shareholders will not receive payment
unless the merger proposal is approved by the affirmative vote of the holders
of at least 75 percent of the shares of Shaw common stock outstanding on the
record date (excluding shares beneficially owned by “Related Persons,” as
defined in Shaw’s charter), as well as the affirmative vote of at least a
majority of the voting power present.

The special meeting will be held Dec. 21, 2012, at 9 a.m. Central at Shaw’s
headquarters located at 4171 Essen Lane in Baton Rouge, La.

Shareholders who have any questions or need assistance voting their shares
should contact Morrow & Co. LLC by calling 800.607.0088 or 203.658.9400.
