EXPLANATORY NOTE

The following information regarding (1) the beneficial ownership of the common stock of Natus Medical Incorporated (the “Company”) by the Company’s executive officers and directors and beneficial owners of 5% or more of the Company’s common stock, (2) the compensation of the Company’s Chief Executive Officer, Chief Financial Officer, and the Company’s other three most highly compensated executive officers who were serving as executive officers at December 31, 2007 (the “named executive officers”), (3) the grant of plan based awards by the Company to the named executive officers during 2007 and (4) compensation of the Company’s directors during 2007 replaces the information contained in the Company’s definitive proxy statement on Schedule 14A filed with the Securities and Exchange Commission on April 28, 2008 relating to the Company’s Annual Stockholders’ Meeting to be held on June 10, 2008. The beneficial ownership table is being revised to add footnote disclosure that one of the Company’s executive officers and one of the Company’s directors have pledged their shares. The summary compensation table and the grants of plan based awards table are being revised to correct the values of the stock and option awards the Company granted to its named executive officers during 2007. In addition, the summary compensation table has been revised to correct the salary information for one of the Company’s named executive officers. The director compensation table is being revised to correct the amount paid prior to October 2007 as an annual retainer to the Chairman of the Company’s Compensation Committee, to correct footnote disclosure regarding the number of shares subject to outstanding options held by one of the Company’s directors and to correct the grant date fair value of the options granted to the Company’s non-employee directors in 2007. All of the revised information has been underlined to make such information more easily identifiable.

(1) Each of the named executive officers other than Mr. Traverso had a range of payouts targeted for 2007 non-equity incentive compensation, based on the Company’s performance as described in “Compensation Discussion and Analysis” above. No bonus payment was made for 2007 performance.
(2) Each of the named executive officers received a grant of restricted shares in 2007. The restricted shares vest as follows: 50% in August 2009, 25% in August 2010, and 25% in August 2011.
(3) Each of the named executive officers received a grant of stock options in 2007. Options were granted with an exercise price equal to the fair market value on the date of grant, which was based on the closing price of the Company’s common stock immediately prior to the award. The shares vest ratably over a 48-month period and may be exercised for six years from the date of grant. Refer to the “Compensation Discussion and Analysis” above for a description of our equity based compensation practices.
(4) These amounts represent the grant date fair value, computed in accordance with SFAS no. 123R, of restricted stock, restricted stock units and stock options granted to our named Executive Officers in 2007.

(2) In June 2007, each non-employee director received a restricted stock award of 2,500 shares that vests in June 2008. The grant date fair value of these awards, computed in accordance with SFAS 123R, was $39,800. The assumptions we use in calculating this amount are discussed in Note 11 of the notes to our consolidated financial statements included in our Annual Report on Form 10-K, except that this amount excludes the impact of estimated forfeitures of equity awards. In 2006, each non-employee director received a restricted stock award of 1,250 shares that vested in June 2007. The amount in this column shows the expense recognized by the Company in 2007 for restricted stock awards.
(3)

The amounts in this column reflect the expenses related to options granted to the Company’s non-employee directors recognized in the Company’s 2007 financial statements pursuant to Statement of Financial Accounting Standards No. 123R, except that a forfeiture rate of zero percent has been used. For a discussion of other valuation assumptions, see Notes 1 and 11 to our consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2007. All of our non-employee Directors received an initial grant of 30,000 options upon their appointment to the board that vests ratably over a 36-month period. Any non-employee directors appointed to the board in the future will receive an initial grant of 10,000


 

shares that vests ratably over a 36-month period. Prior to December 31, 2006, each director received an additional grant of 10,000 options annually. For 2006, each director received a grant of 7,500 options and restricted stock as discussed above and for 2007, each director received a grant of 5,000 options and restricted stock as discussed above. All options granted to directors other than their initial grant vest ratably over a 12-month period. Stock option grants were established using the same procedure for timing and price as is used for employees. Refer to the “Compensation Discussion and Analysis” above for a description of our equity based compensation practices. The grant date fair value of the options granted to our non-employee directors in 2007, computed in accordance with SFAS 123R, was $31,446. The assumptions we use in calculating this amount are discussed in Note 11 of the notes to our consolidated financial statements included in our Annual Report on Form 10-K, except that this amount excludes the impact of estimated forfeitures of equity awards.

(4) At December 31, 2007, Ms. Engibous had 52,500 options and 2,500 unvested restricted shares outstanding, Mr. Gunst had 47,500 options and 2,500 unvested restricted shares outstanding, Mr. Ludlum had 5,000 options and 2,500 unvested restricted shares outstanding, Mr. Michael had 52,500 options and 2,500 unvested restricted shares outstanding, and Mr. Moore had 72,500 options and 2,500 unvested restricted shares outstanding.
