In consideration of your acceptance of this Agreement and subject to your meeting in full your obligations under it, the Company will provide you the following: (a) The Company shall cause those of your Class A and Class B stock options which remain unvested on the Separation Date to vest. Further, you agree to the cancellation of all of your Class A and Class B stock options in return for an amount of cash equal to (i) the product of (A) the Per Share Deal Price multiplied by (B) the number of shares of Class A Common Stock of Nortek Holdings, Inc. subject to the cancelled options minus (ii) the aggregate exercise prices with respect to all such options. Provided this Agreement is in effect, payment will be made by wire transfer on August 27, 2004. (b) You will remain a Participant in the Nortek, Inc. Supplemental Executive Retirement Plan C ("SERP-C"), subject to its current terms. The Company, however, shall cause SERP-C to be amended such that you may elect to begin receiving benefits under SERP-C as of September 1, 2006 with no reduction in benefits for early retirement. The terms of your participation in SERP-C shall otherwise remain unchanged, other than as stated in Paragraph 5(e). Also, it is understood and agreed that none of the payments to be made to you under this Agreement or the Change of Control Plan, addressed below, shall be included in the calculation of your benefits under SERP-C. (c) The Company will pay your membership dues in the Wannamoisett Country Club through December 31, 2004 and you may continue to use that membership through that date. You will be responsible for all personal expenses incurred. -1- (d) Although you will cease to be a member in the TPC Club of Norton, Massachusetts as of the Separation Date, the Company will designate you as eligible to use the Company's membership for the period of one year from the Separation Date, through August 25, 2005. You will be responsible for all personal expenses incurred. (e) The Company will provide you tax consulting services for calendar 2004 in accordance with its policy for active executive employees. (f) The Company will provide you six months of executive outplacement services, at the Company's cost, through Right Management Associates. (g) On the Separation Date, the Company will transfer ownership to you of the two cell phones and the computer hardware at your home which were previously provided for your business use. You will be responsible for all costs related to use of those phones and that equipment after the Separation Date. 2. FINAL PAY, EXPENSES AND CHANGE OF CONTROL PLAN PARTICIPATION. In addition to the foregoing, (a) You have received your salary for the month of August. The Company will provide you any terminal vacation pay to which you are entitled. (b) The Company will reimburse any business expenses which you incurred on or before the Separation Date and which are subject to reimbursement under current Company policies, provided that you submit those expenses and any supporting documentation and substantiation required within 90 days of the Separation Date. (c) You will be entitled to the following benefits under the Nortek, Inc. Change of Control Severance Benefit Plan for Key Employees (as amended June 12, 1997 and November 19, 2002) (the "Change of Control Plan"), in accordance with its terms: (i) a payment of $120,000, which is 20% of your current salary, (ii) 24 months of payments in the amount of $122,917 per month (based on your current base salary of $600,000 and a high bonus of $875,000) and (iii) 24 months of continued coverage under certain designated benefit plans or, if elected within 15 days of the Separation Date, a payment in lieu thereof, all as specified in the Change of Control Plan. 3. WITHHOLDING. All payments by the Company under this Agreement will be reduced by all taxes and other amounts that the Company is required to withhold under applicable law. 4. STATUS OF BENEFITS AND ACKNOWLEDGEMENT OF FULL PAYMENT. Except as provided in the second paragraph of Section 5 of the Change of Control Plan and referenced in Paragraph 2(c) above, your participation in all benefit plans and perquisites of the Company will end as of the Separation Date, in accordance with the terms of those -2- plans and perquisites. You agree that, except as expressly provided under this Agreement, no further compensation of any kind is owed to you. 5. CONTINUING EMPLOYEE OBLIGATIONS. (a) You agree that you will continue to protect Confidential Information, as defined below, and will not, directly or indirectly, use or disclose it. (b) You also agree that you will not disclose this Agreement or any of its terms or provisions, directly or by implication, except to members of your immediate family and to your legal and tax advisors, and then only on condition that they agree not to further disclose this Agreement or any of its terms or provisions to others. (c) In signing this Agreement, you give the Company assurance that you will return to it, no later than September 15, 2004, any and all documents, materials and information (whether in hardcopy, on electronic media or otherwise) related to the business (whether present or otherwise) of the Company and its Affiliates, and all copies, and all keys, credit cards and all other property of the Company in your possession or control, excluding only that equipment transferred to you under Paragraph 1(g). (d) You agree to cooperate with the Company hereafter with respect to all matters arising during or related to your employment, including but not limited to all matters in connection with any governmental investigation, litigation or regulatory or other proceeding which may have arisen or which may arise following the signing of this Agreement. The Company will reimburse all reasonable and necessary out-of-pocket expenses incurred in complying with Company requests hereunder. Following the conclusion of the 24 months of payments to be provided you under the Change in Control Plan, the Company will reimburse, on a per diem basis, any salary, in excess of ten days' salary in any calendar year, which you must forego in order to comply with Company requests thereafter, provided that the Company has approved the time expenditure in advance. (e) You acknowledge that during your employment you have had access to Confidential Information which, if disclosed, would assist in competition against the Company and its Affiliates and that you have also generated goodwill for the Company and its Affiliates in the course of your employment. Therefore, you agree that the following restrictions on your activities after your employment are necessary to protect the goodwill, Confidential Information and other legitimate interests of the Company and its Affiliates and the Company agrees that your meeting the following obligations will satisfy as well your obligations with respect to non-competition under SERP-C: (i) You agree that, during the four-year period immediately following termination of your employment (the "Non-Competition Period"), you will not, directly or indirectly, whether as owner, partner, investor, consultant, agent, employee, co-venturer or otherwise, compete in North America with the Company or any of its Affiliates -3- in any business in which any of them was engaged or actively planning to engage on the Separation Date. Specifically, but without limiting the foregoing, you agree not to work or provide services, in any capacity, whether as an employee, independent contractor or otherwise, whether with or without compensation, to any Person that is engaged in North America in any business that is competitive with the business of the Company or its Affiliates, as conducted or in planning during your employment with the Company or any of its Affiliates. (ii) You agree that, during the Non-Competition Period, you will not, and will not assist any other Person knowingly to, (A) hire any employee of the Company or any of its Affiliates or seek to persuade any employee of the Company or any of its Affiliates to discontinue employment, (B) solicit or encourage any customer of the Company or any of its Affiliates or independent contractor providing services to the Company or any of its Affiliates to terminate or diminish its relationship with them or (C) seek to persuade any customer or prospective customer of the Company or any of its Affiliates to conduct with anyone else any business or activity that such customer or prospective customer conducts or could conduct with the Company or any of its Affiliates. (f) In signing this Agreement, you give the Company assurance that you have carefully read and considered all the terms and conditions of this Agreement, including the restraints imposed on you under Paragraph 5(a) and Paragraph 5(e) hereof. You agree without reservation that these restraints are necessary for the reasonable and proper protection of the Company and its Affiliates and that each and every one of the restraints is reasonable in respect to subject matter, length of time and geographic area. You further agree that, were you to breach any of the covenants contained in Paragraph 5(a) or Paragraph 5(e), the damage to the Company and its Affiliates would be irreparable. You therefore agree that the Company, in addition to any other remedies available to it, shall be entitled to preliminary and permanent injunctive relief against any breach or threatened breach by you of any of those covenants, without having to post bond. You and the Company further agree that, in the event that any provision of Paragraph 5(a) or Paragraph 5(e) is determined by any court of competent jurisdiction to be unenforceable by reason of its being extended over too great a time, too large a geographic area or too great a range of activities, that provision shall be deemed to be modified to permit its enforcement to the maximum extent permitted by law. 6.
