If such information is not in the Company’s possession, custody or control, such information should be requested from Automatic Data Processing — Investor Communications Services; and

     (g) All lists on computer tapes or other electronic media and the relevant processing data and printouts (as described in paragraph (b) above) containing the name and address of and number of shares of Common Stock of the Company attributable to any participant in any employee stock ownership plan, employee stock purchase plan or other employee compensation or benefit plan of the Company in which the decision to vote shares of stock of the Company held by such plan is made, directly or indirectly, individually or collectively, by the participants in the plan and the method(s) by which HLL or its attorneys, representatives or agents may communicate with each such participant, as well as the name, affiliation and telephone number of the trustee or administrator of each such plan, and a detailed explanation of the treatment not only of shares for which the trustee or administrator receives instructions from participants, but also shares for which either the trustee or administrator does not receive instructions or shares that are outstanding in the plan but are unallocated to any participant.
