filing because it may be deemed to constitute a "group" with the Reporting

Item 3.   SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION.

     Item 3 hereby is partially amended with respect to Alpine and Keystone to
read as follows:

     The source and amount of the funds used by Alpine and Keystone to
purchase shares of the Stock are as follows:

REPORTING PERSON     SOURCE OF FUNDS        AMOUNT OF FUNDS

Alpine              Working Capital(1)       $32,688,366.08(2)

Keystone            Working Capital(1)       $ 2,428,702.60

(1)  As used herein, the term "Working Capital" includes income from the
     business operations of the entity plus sums borrowed from banks and
     brokerage firm margin accounts to operate such business in general.  None
     of the funds reported herein as "Working Capital" were borrowed or
     otherwise obtained for the specific purpose of acquiring, handling,
     trading or voting the Stock.

(2)  This figure represents the total amount expended by Alpine for all
     purchases of shares of the Stock without subtracting sales; therefore,
     such figure does not represent Alpine's net investment in shares of the
