                  "The Issuer's Class B Shares were acquired by the Reporting
Persons, other than CBSBI and W/CBS HCI which previously owned the subject
shares, pursuant to the merger of CBS, of which CBSBI and W/CBS HCI were,
respectively, indirect and direct wholly owned subsidiaries, with and into
Viacom on May 4, 2000. The Reporting Persons may, at any time and from time to
time, purchase additional Common Shares of the Issuer and may dispose of any and
all Common Shares of the Issuer held by them.

                  On October 30, 2000, Viacom, IBC Merger Corp., a Delaware
corporation and a direct wholly owned subsidiary of Viacom ("Merger Sub"), and
the Issuer entered into a definitive agreement and plan of merger (the "Merger
Agreement") pursuant to which the Issuer will merge with and into Merger Sub
(the "Merger") and Viacom will acquire all the issued and outstanding Class A
Shares not currently owned by Viacom. In the Merger, each outstanding Class A
Share will be converted into the right to receive 0.592 of a share of Viacom
Class B Common Stock, par value $.01 per share.


                  On January 5, 2001, Viacom and the Issuer announced that
Infinity would hold a meeting of its stockholders to seek approval of the Merger
by the Issuer's minority stockholders, and that Viacom had entered into a voting
agreement dated as of January 4, 2001 (the "Voting Agreement") with two
stockholders of the Issuer, William S. Levine and Arturo Moreno. Pursuant to the
Voting Agreement, Messrs. Levine and Moreno have agreed to vote their Class A
Shares in favor of the Merger Agreement, the Merger and any actions required in
furtherance thereof. At its stockholders meeting, Infinity will seek approval of
the Merger by holders of 66 2/3% of the outstanding Common Shares, other than
those owned by Viacom or subject to the Voting Agreement.

                  Viacom anticipates that upon completion of the Merger, Viacom
will seek to cause the Class A Shares to be delisted from trading on the New
York Stock Exchange and to cause the termination of registration of the Class A
Shares pursuant to Section 12 of the Securities and Exchange Act of 1934, as
amended (the "Act").

                  A copy of the Merger Agreement is attached hereto as Exhibit
99.1 and is incorporated by reference herein. A copy of the press release issued
by Viacom and the Issuer on October 31, 2000 is attached hereto as Exhibit 99.2.
A copy of the Voting Agreement is attached hereto as Exhibit 99.3 and is
incorporated by reference herein. A copy of the press release issued by Viacom
and the Issuer on January 5, 2001 is attached hereto as Exhibit 99.4.

                  Other than as set forth herein, the Reporting Persons have no
current plan or proposal which relates to, or would result in, any of the
actions enumerated in subparagraphs (a) through (j) of Item 4 of Schedule 13D."
