A "Sale Day" shall be any day during the Plan Sales Period that the limit price specified in Paragraph 4 below is met; PROVIDED, HOWEVER, that if any Sale Day is not a Trading Day, such Sale Day shall be deemed to fall on the next succeeding Trading Day within the Plan Sales Period. 3. Bessemer shall effect sales of a maximum of 450,000 shares of Stock under the Trading Plan. Subject to the foregoing limitation and the minimum Sale Price set forth below, Bessemer shall have full discretion to effect sales of the Stock. 4. The "Sale Price" shall be the market price per share of Stock on the Sale Day, provided that such market price is not less than $30.00 per share. 5. The maximum number of shares of Stock that may be sold under paragraph 3 and the Sale Price shall be adjusted automatically on a proportionate basis to take into account any stock split, reverse stock split or stock dividend with respect to the Stock or any change in capitalization with respect to Issuer that occurs while the Trading Plan is in effect. 6.

The Trading Plan is consistent with Issuer's insider trading policies, and, to the best of Issuer's knowledge, there are no legal, contractual or regulatory restrictions imposed by Issuer applicable to Seller or Seller's affiliates as of the date of this representation that would prohibit either Seller from entering into the Trading Plan or any sale pursuant to the Trading Plan. 3. To avoid delays in connection with transfers of stock certificates and settlement of transactions under the Trading Plan, and in acknowledgment of Bessemer's agreement in paragraph 6(b) of the Trading Plan that sales of Stock under the Trading Plan will be effected in compliance with Rule 144, Issuer agrees that it will, immediately upon Seller's directing delivery of Stock into an account at Bessemer in the name of and for the benefit of Seller, instruct its transfer agent to process the transfer of shares and issue a new certificate to Seller that does not bear any legend or statement restricting its transferability to a buyer.
