Item 5.02  Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

On and effective June 6, 2007, the Governance, Nominating & Compensation (GNC) Committee of the Board of Directors of the Company approved stock option grants, restricted stock awards and performance unit awards to certain key employees under the Company's various stockholder approved incentive plans. These included the following grants and awards to certain executives designated as "named executive officers" in the Company's 2007 proxy statement:

The restricted stock awards provide for restrictions to lapse on the third anniversary of the date of grant, subject to the recipient's continuous employment with the Company or a subsidiary from the date of grant to the date restrictions lapse. Restrictions may lapse earlier as provided in the applicable incentive plan and award agreement or as a result of a change in control.

The option grants have seven-year terms and vest in one-third installments on the first, second and third anniversaries of the date of grant, subject to the recipient's continuous employment with the Company or a subsidiary from the date of grant to the date of vesting. Options may vest earlier as provided in the applicable incentive plan and award agreement, including in the event of a change in control. Each option has an exercise price of $44.70 per share, which is the average of the high and low trading prices on the New York Stock Exchange on the date of grant.

Performance unit awards will have a value at payout of $1.00 per unit earned at the end of the performance cycle (December 31, 2009). The number of units awarded will be adjusted at the end of the performance cycle depending on the Company's cumulative earnings per share, or EPS, over the performance cycle (January 1, 2007 to December 31, 2009). At threshold, payout is 50%. At target, payout is 100%. At maximum, payout is 150%. Payout between threshold and target and between target and maximum will be pro-rated using a straight-line interpolation. EPS will be adjusted to eliminate the effects of extraordinary events occurring in the performance cycle, such as mergers, acquisitions or divestitures. A participant's performance unit award shall terminate if the participant does not remain continually employed by the Company or does not continue to perform services for the Company at all times during the performance cycle, except (a) in the event of a change in control, the applicable performance cycle shall be deemed complete and awards shall be deemed earned at target, (b) in the event of death or disability during the cycle, the performance cycle shall be deemed complete and awards shall be deemed earned at target or (c) as may otherwise be determined by the GNC Committee, which is responsible for administering the applicable incentive plan.

Also on June 6, 2007, the Board of Directors adopted revised corporate governance guidelines to provide, among other things, for stock ownership targets to be met by non-employee directors and certain senior executives. Under the revised guidelines, non-employee directors are expected to own a number of shares of common stock having a value at least equal to two times the annual cash retainer for service as a director (without regard to any committee chair retainers). Each of the Chief Executive Officer, President and Chief Operating Officer and each Executive or Senior Vice President reporting to the CEO or COO is expected to own a number of shares of common stock having a value at least equal to a specified multiple of such executive's base salary (5x in the case of the CEO, 3x in the case of the COO and 2x in all other cases). The non-employee directors and executives have a transition period within which to comply, and the GNC Committee will review progress toward the targets on an annual basis. Executives over age 62 are exempt from the requirements. A copy of the revised corporate governance guidelines is posted on the Company's website, www.natcogroup.com, under the caption "Investor Relations" in the Corporate Governance section. A copy of the guidelines will be provided to any stockholder upon request to the Company's Corporate Secretary, at the address listed on the cover to this report.

Effective upon adoption of the ownership guidelines, the GNC Committee waived stock retention requirements in previously granted option and restricted stock award agreements applicable to employees, as the guidelines supersede these requirements.
