Explanation of Responses:

* If the form is filed by more than one reporting person, see Instruction 4(b)(v).
** Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1) Stock Units issued and held for the account of the reporting person under the Amended and Restated 2004 Nonemployee Director Equity and Deferred Compensation Plan (the "Plan"). In connection with any distribution to the reporting person under the Plan, Stock Units are payable in shares of common stock on a 1 for 1 basis. The reporting person is fully vested in all Stock Units issued to him and held for his account, and there is no expiration date.
(2) Pursuant to the Plan, each Stock Unit is entitled to receive the same dividends as a share of common stock. These Stock Units were issued to the reporting person pursuant to his election to receive Stock Units in lieu of the cash dividend declared by Sun Hydraulics in June 2011, which was payable to stockholders of record as of June 30, 2011. The cash dividend was payable on the number of Stock Units held after giving effect to the stock dividend declared in June 2011, which dividend provided for the issuance of one additional share for every two shares held of record on June 30, 2011. The number of Stock Units and the price of the Stock Units have been adjusted to give effect to the stock dividend.
(3) Includes 2,470.70 additional Stock Units received as a result of the stock dividend declared in June 2011.
