Merger Synergy Restricted Stock Agreement This Agreement, made and entered into as of October 19, 1999, (the "Agreement") by and between CK Witco Corporation (the "Corporation") and Name (the "Executive") of Town. WHEREAS, Crompton & Knowles Corporation ("C&K") and Witco Corporation ("Witco") merged on September 1, 1999, to form the Corporation; WHEREAS, the merger of C&K and Witco presents an opportunity for the Corporation to realize significant cost savings through synergies resulting from the merger; and WHEREAS, by virtue of the Executive's position with the Corporation, the Executive can make a valuable contribution toward achievement by the Corporation of merger related cost savings, and the Corporation is offering incentives to the Executive and other senior executives of the Corporation to work to achieve $60 million in annual savings from such synergies; NOW, THEREFORE, the Executive and the Corporation hereby agree as follows: 1. Definitions. For purposes of this Agreement, the following terms shall have the following meanings: (a) "Performance Period" shall mean the period September 1, 1999, to December 31, 2001. (b) "Synergy Cost Savings" shall mean total annual savings as follows: (i) Savings from headcount reductions. Payroll and benefit savings from headcount reductions will be determined by comparison to a baseline of June 30, 1999. Spending for payroll and benefits based on the employee census as of the baseline date will be annualized and compared to actual spending (adjusted to eliminate wage and benefit increases that are effective on or after January 1, 2000) for each of fiscal years 2000 and 2001. (ii) Savings from expense reductions. Non- capitalized expense reductions with respect to consultants, travel and entertainment, logistics, purchasing, insurance, rent, purchased supplies and services and communications will be determined by the comparison of actual annual spending for those categories of expense in each of fiscal years 2000 and 2001 to the total combined spending of Crompton & Knowles, Witco and CK Witco for the same categories of expense in 1999. (iii) Manufacturing savings. Manufacturing savings from consolidation and shutdown of plants and other facilities and improvements in manufacturing operations will be determined by comparison of actual spending in each of fiscal years 2000 and 2001 to a baseline of June 30, 1999. (iv) Interest expense and tax savings. Savings from lower interest expense for each of fiscal years 2000 and 2001 will be determined by the comparison of actual interest expense in those years to combined interest expense for Crompton & Knowles, Witco and CK Witco for 1999. Savings, if any, from a lower effective tax rate will be measured based on any improvement in the effective consolidated tax rate in years after 1999 from 39.2% (the pro forma tax rate for CK Witco as if the merger had occurred on January 1, 1999). KPMG LLP will report to the Organization, Compensation and Governance Committee of the Corporation's board of directors (the "Committee") on the savings achieved as of the last day of each complete fiscal year of the Corporation during the Performance Period. (c) "Retirement" shall mean cessation of the Executive's employment with the Corporation or a subsidiary of the Corporation occurring on or after the Executive's sixty-second (62nd) birthday. (d) "Cause" shall mean (i) the Executive's willful and continued failure to substantially perform assigned duties with the Corporation or its subsidiary corporations (other than any such failure resulting from incapacity due to physical or mental illness or any such actual or anticipated failure resulting from termination for Good Reason), after a demand for substantial performance is delivered to the Executive by the Board of Directors of the Corporation by which the Executive is employed (the "Board"), specifically identifying the manner in which the Board believes that the duties have not been substantially performed, or (ii) the Executive's willful conduct which is demonstrably and materially injurious to the Corporation or any subsidiary corporation by which the Executive is employed. For purposes of this subsection 2(c), no act, or failure to act, shall be considered "willful" unless done, or omitted to be done, not in good faith and without reasonable belief that such action or omission was in the best interest of the Corporation and the subsidiary corporation, if any, by which the Executive is employed. (e) "Good Reason" shall mean (i) the assignment to the Executive of any duties inconsistent in any respect with the Executive's position (including status, offices, titles, and reporting requirements), authority, duties or responsibilities as contemplated by any employment agreement between the Executive and the Corporation or a subsidiary of the Corporation, or any other action by the Corporation or the subsidiary corporation, if any, by which the Executive is employed which results in a diminishment in such position, authority, duties, or responsibilities, other than an insubstantial and inadvertent action which is remedied by the Corporation or such subsidiary corporation promptly after receipt of notice thereof given by the Executive; (ii) any failure by the Corporation or the subsidiary corporation, if any, by which the Executive is employed to comply with any of the provisions of any employment agreement between the Executive and the Corporation or such subsidiary corporation, other than an insubstantial and inadvertent failure which is remedied by the Corporation or such subsidiary corporation promptly after receipt of notice thereof given by the Executive; (iii) any change not concurred in by the Executive in the location of the office at which the Executive is principally based on the date hereof, except for travel reasonably required in the performance of the Executive's responsibilities and substantially consistent with prior business travel obligations of the Executive; or (iv) any purported termination by the Corporation or the subsidiary corporation, if any, by which the Executive is employed of the Executive's employment otherwise than as permitted by any employment agreement between the Executive and the Corporation or such subsidiary corporation.
