Explanation of Responses:

* If the form is filed by more than one reporting person, see Instruction 4(b)(v).
** Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1) Each performance share represents a contingent right to receive one share of CMC common Stock.
(2) Each performance share is a restricted stock unit representing a contingent right to receive one share of CMC common stock. The Units vest as follows: (i) 50% if the Company ranks at or greater than the 50th percentile but less than the 60th percentile on a Total Stockholder Return basis as compared to its Peer Group; and 100% if the Company ranks at or greater than the 60th percentile on a Total Stockholder Return basis as compared to its Peer Group. Vesting will be calculated on a straight line interpolation basis for a rank on a Total Stockholder Return basis as compared to its Peer Group between the 50th percentile (at a vesting percentage of 50%) and 60th percentile (with a vesting percentage of 100%). For the measurement periods mentioned above, the Total Stockholder Return will be based on the average of the closing prices on the principal market for each trading day for the month of June 2010 compared to the month of June 2013.
(3) Award of restricted stock units under the 2006 Long-Term Equity Incentive Plan. Each restricted stock unit represents a contingent right to receive one share of CMC common stock.
(4) The restricted stock units vest over four years in two vest periods: 50% after 2 years and the remaining 50% after four years.
