RECITALS

This Transition and Release (“Agreement”) is made by and between William H. Lawrenson, (“Employee”) and Natus Medical Inc. (“Company”) (collectively referred to as the “Parties”):

WHEREAS, Employee is an employee and officer of the Company;

WHEREAS, the Company and Employee entered into a Employment, Confidential Information and Invention Assignment Agreement (the “Confidentiality Agreement”) and an Indemnity Agreement, and;

WHEREAS, the Employee has resigned his employment with Company effective August 31, 2002 (the “Termination Date”)

WHEREAS, the Company and Employee have entered into a stock option agreements dated December 17, 1997, October 23, 1998, May 5, 1999, July 6, 1999, May 9, 2000 and April 20, 2001 granting me the option to purchase 129,803 total shares of the Company’s common stock subject to the terms and conditions of the Company’s 1991 and 2000 Stock Option Plans and the Stock Option Agreement (the “Stock Agreements”):

WHEREAS, the Parties, and each of them, wish to resolve any and all disputes, claims, complaints, grievances, charges, actions, petitions and demands that the Employee may have against the Company as defined herein, including, but not limited to, any and all claims arising or in any way related to Employee’s employment with, or separation from, the Company;

1    Resignation and Transition

Employee hereby tenders his resignation as Chief Financial Officer of Natus Medical Inc. (the Company) effective August 31, 2002 (the Termination Date), under the terms and conditions in this agreement.

Upon execution of this agreement, the transition period (the Transition Period) shall commence, which will terminate August 31, 2002.

Employee will remain as Chief Financial Officer of the Company for as long as the Company deems fit, but in no event after the Termination Date. The Company will inform Employee of the date on which it wishes Employee to step down as CFO, at its convenience, at which time and in exchange for consideration detailed hereunder, including continuation of salary and benefits through the Termination Date, the Employee will resign as the Chief Financial Officer, and as a Director of Company’s Subsidiaries, (collectively “CFO”).

If Employee ceases to serve as CFO prior to the Termination Date, it will not terminate the Employee’s employment during the Transition Period, but such resignation as CFO will terminate his status as an officer and manager of the Company. During the Transition Period and subsequent to resigning as CFO, Employee will no longer be an officer within the Company, and will become a regular staff employee reporting to the President of the Company or to the President’s designee.

1

Employee will devote 100% of his time to the Company during April and May 2002; thereafter during June and July 2002 Employee will devote 60% (nominally three days per five day week) of his time to the Company; during August 2002 until the Termination Date, Employee shall be given a leave of absence and shall not be required to attend the Company.

During the Transition Period, the Company may hold Employee on either active or paid leave of absence status, as the Company may, at its option, determine and inform Employee by written notice. If Employee is on active status during the Transition Period, Employee will perform his duties as CFO, including, but not limited to:

• Assist the Company in finding and hiring a replacement Chief Financial Officer (hereinafter New CFO),

• Acquaint the New CFO with the systems and operation of the Finance and Administrative Departments,

• Assist in the transition of staff to New CFO,

• Introduce New CFO to the investment community and provide New CFO with contact lists,

• Assist in the completion of the BaaN V implementation,

• When requested to do so by the Company, promptly resign as Chief Financial Officer of the Company and as Director of its subsidiaries, and

• Perform other reasonable mutually agreeable tasks associated with the transition.

During the Transition Period and through and until the Termination Date, on each regularly scheduled pay day, Company will pay Employee his current full-time (100%) salary and benefits and reimburse Employee actual and reasonable travel costs associated with approved travel on behalf of the Company.

On the Termination Date, the Company will pay Employee the remainder of his regular monthly salary for August 2002 calculated from the end of the previous pay period through August 31, as well as any and all accrued vacation and other amounts normally due terminating employees, and make available to Employee those continuation benefits, such as normal COBRA benefits, and any other benefits as are normally offered other employees at the time of their termination. Employee’s health insurance benefits will cease at the end of the month which contains the Termination Date, subject to Employee’s right to continue his health insurance under COBRA. Employee’s participation in all other benefits and incidents of employment will cease on the Termination Date. Employee will cease accruing employee benefits as of the Termination Date, except as otherwise specified herein, including, but not limited to, vacation time and paid time off.

In the event that the BaaN IV system has been successfully migrated to the BaaN V system by not later than the Termination Date, the company shall accelerate the vesting of approximately 15,000 unvested options to purchase shares associated with Employee’s option dated May 9, 2000. The exercise of the options shall continue to be subject to the applicable stock option agreements.

Employee shall be permitted to retain possession of his Company-provided laptop computer (or reasonable substitute/replacement thereof), provided that all Company information or data shall be removed therefrom.
