            AMERICAN LIST FURNISHES ADDITIONAL INFORMATION REGARDING
             MERGER AGREEMENT AND CLARIFIES FOURTH QUARTER EARNINGS

American List Corp. (AMEX:AMZ) furnishes the following additional information
with respect to the number of shares of common stock of Snyder Communications,
Inc. (NYSE:SNC) to be issued for each share of American List in connection with
the previously announced merger. In the event that the average trading price of
Snyder common stock for the twenty day period ending on the third day prior to
the closing (the "Average Trading Price") equals or exceeds $32.00, one share of
Snyder common stock will be issued for each share of American List common stock.
In the event that the Average Trading Price equals or exceeds $28.00 but is less
than $32.00, the number of shares of Snyder common stock issuable for each share
of American List common stock will equal the quotient of $32.00 divided by the
Average Trading Price. In the event that the Average Trading Price equals or
exceeds $26.00 but is less than $28.00, 1.14 shares of Snyder common stock will
be issuable for each share of American List common stock. In the event that the
Average Trading Price is less than $26.00 and the merger agreement is not
otherwise terminated in accordance with its terms, the number of shares of
Snyder common stock issuable for each share of American List common stock will
equal the quotient of $29.71 divided by the Average Trading Price.

The Company also corrects its earlier announcement of earnings for the fourth
quarter of fiscal 1996. The Company announces that for the fourth quarter ended
February 29, 1996, it reported revenues of $5.7 million and net income of $0.55
per share rather than $0.42 per share.
