Item 5.02

On March 6, 2007 Minerals Technologies Inc. filed a current report on Form 8-K disclosing that the Compensation Committee (the "Committee") of the Board of Directors approved targets and granted awards under the 2007-2009 long-term incentive program. Three types of awards are utilized as part of this program: stock options, deferred restricted stock units and performance units.

On October 24, 2007 the Committee approved revised performance targets for the performance units: while previously the value of a performance unit was dependent on the Company's return on capital and total shareholder value, it is now dependent on return on capital and earnings per share. In addition, the Committee raised the maximum performance thresholds necessary for a performance unit to be worth $300. Previously, a performance unit was worth $300 if performance was greater than or equal to 125% of target. Now, a performance unit is worth $300 if performance is greater than or equal to 170% of target for the earnings per share target and 200% of target for the return on capital target.

In addition, the Committee also imposed a cap on the maximum payout of a performance unit based on the Company's total shareholder return ("TSR") in relation to the average TSR of the Company's peer group. If the Company's TSR is lower than that of its peer group, the maximum payout of a performance unit will be $100. In this event, any amount earned over $100 for a performance unit will not be paid out at the end of the performance period, but may be paid out the following year if the Company's TSR equals or exceeds the average TSR of its peer group.

As previously disclosed, performance units vest at the end of a three-year performance period. If performance does not meet minimum threshold levels (75% of target), the unit will be worth $0. At target performance, a unit is worth $100 and may be worth up to $300 at maximum performance levels. The performance unit value is paid out in cash at the end of the performance period.
