Following a total shareholder return on the Hydro share of 49 percent in 2005, the employees of Norsk Hydro ASA have once again been offered to purchase Hydro shares with a value of NOK 12,000 at a 50 percent discount.

This is a general arrangement offered to employees in Norway, where 87 percent of the employees entitled to the offer have subscribed and have been allocated 15 shares at NOK 388.85 per share.

The total number of shares allocated is 151,005.

The terms are according to Hydro's share purchase plan for employees in Norway where at least a 12 percent total shareholder return is required to obtain the 50 percent discount.

Norsk Hydro ASA holds 8,664,959 own shares after this transaction.
