Item 3.02. Unregistered Sales of Equity Securities.

     On January 10, 2005, the Registrant voluntarily issued 73,290 shares of its common stock to the Sun Hydraulics Employee Stock Ownership Plan (“ESOP”) for the benefit of its United States employees. The ESOP paid no consideration for the shares. The shares were valued at $14.46 per share, the closing price of the stock on January 7, 2004, the last business day before the date of issuance. The shares will be allocated pursuant to the terms of the ESOP to the Registrant’s United States employees. The issuance of the shares was exempt from registration under the Securities Act of 1933 as the contribution of the shares to the ESOP for the benefit of the Registrant’s employees, without the payment of consideration by the ESOP or employees, does not constitute a sale of the common stock for purposes of the Act.
