                      THE SHAW GROUP INC. DECLARES DIVIDEND
                 DISTRIBUTION OF PREFERRED SHARE PURCHASE RIGHTS

Baton Rouge, Louisiana, July 13, 2001 - The Shaw Group Inc. (NYSE: SGR) ("Shaw"
or "the Company") Board of Directors today declared a dividend distribution of
one Preferred Share Purchase Right on each outstanding share of the Company's
common stock.

J.M. Bernhard, Jr., Shaw's Chairman, President and Chief Executive Officer,
stated, "The Rights are designed to assure that all of the Company's
shareholders receive fair and equal treatment in the event of any proposed
takeover of the Company and to guard against abusive tactics to gain control of
the Company without paying all shareholders a premium for that control. The
Rights are not being adopted in response to any specific takeover threat."

The Rights are intended to enable all Company shareholders to realize the
long-term value of their investment in the Company. The Rights will not prevent
a takeover, but should encourage anyone seeking to acquire the Company to
negotiate with the Board prior to attempting a takeover.

The Rights will be exercisable only if a person or group acquires 15% or more of
the Company's common stock or commences a tender offer, the consummation of
which would result in ownership by a person or group of 15% or more of the
common stock. Each Right will entitle shareholders to buy one one-hundredth of a
share of a new series of junior participating preferred stock at an exercise
price of $170.00 per share.

If a person or group acquires 15% or more of the Company's outstanding common
stock, each Right will entitle its holder (other than such person or members of
such group) to purchase, at the Right's then-current exercise price, a number of
the Company's common shares having a market value of twice such price. In
addition, if the Company is acquired in a merger or other business combination
transaction after a person has acquired 15% or more of the Company's outstanding
common stock, each Right will entitle its holder to purchase, at the Right's
then-current exercise price, a number of the acquiring company's common shares
having a market value of twice such price. The acquiring person will not be
entitled to exercise these Rights.

Prior to the acquisition by a person or group of beneficial ownership of 15% or
more of the Company's common stock, the Rights are redeemable for one cent per
Right at the option of the Board of Directors.

The Board of Directors is also authorized to reduce the 15% thresholds referred
to above to not less than 10%.

The dividend distribution will be made on July 31, 2001, payable to shareholders
of record on that date, and is not taxable to shareholders. The Rights will
expire on July 9, 2011.
