ITEM 5.  OTHER EVENTS

         On November 1, 1999, FirstCom Corporation, a Texas corporation
("FirstCom"), entered into an Agreement and Plan of Merger (the "Merger
Agreement") with AT&T Corp., a New York corporation ("AT&T"), Kiri Inc., a
Delaware corporation ("AT&T Latin America") and an indirect wholly-owned
subsidiary of AT&T, and Frantis, Inc., a Delaware corporation which is a direct
wholly-owned subsidiary of AT&T Latin America ("Frantis"). The Merger Agreement
provides for the merger (the "Merger") of FirstCom with and into Frantis.
Pursuant to the Merger, the shareholders of FirstCom will receive (i) one share
of Class A Common Stock, par value $0.01 per share ("Class A Shares"), of AT&T
Latin America in exchange for each share of common stock, par value $0.001 per
share, of FirstCom; and (ii) one share of Series A convertible preferred stock,
par value $0.001 per share, of AT&T Latin America in exchange for each share of
Series A Preferred Stock, par value $0.001 per share, of FirstCom. The terms of
the Merger Agreement and the Merger were determined through arms-length
negotiations among the parties.

         On August 20, 1999, Jamtis, Inc., a Delaware corporation and an
indirect wholly-owned subsidiary of AT&T ("Jamtis"), entered into agreements
(the "Netstream Acquisition Agreements") to acquire quotas (the "Netstream
Shares") representing 100% of the outstanding equity interest in Netstream
Telecom Ltda., a Brazilian company ("Netstream"). Further, pursuant to the
Netstream Acquisition Agreements, Promon Tecnologia S.A., a Brazilian
corporation (sociedade anonima) (together with its affiliates, "Promon"), has
agreed to purchase, prior to the closing under the Merger Agreement, a 10%
interest in the capital of AT&T Latin America, in the form of Class A Shares.
Prior to the closing of the Merger, Netstream will become an indirect
wholly-owned subsidiary of AT&T Latin America.

         Upon consummation of the Merger, on a fully-diluted basis AT&T will own
approximately 60% of the shares of common stock of AT&T Latin America, in the
form of Class B Common Stock ("Class B Shares"), Promon will own approximately
6% of the shares of common stock of AT&T Latin America, in the form of Class A
Shares, and the former shareholders of FirstCom will own approximately 34% of
the common stock of AT&T Latin America in the form of Class A Shares.

         Each Class A Share will be entitled to one vote per share and each
Class B Share will be entitled to ten votes per share, on all matters submitted
to a vote of the stockholders of AT&T Latin America. Upon the closing of the
Merger, the Class A Shares will be listed for trading on the NASDAQ National
Market, and the common stock of FirstCom will no longer be traded.

         Upon the closing under the Merger Agreement, AT&T and AT&T Latin
America will enter into a "Regional Vehicle Agreement" that provides for various
ways in which AT&T Latin America will interface with AT&T, AT&T's Concert
venture with British Telecom and AT&T's Global Network services business. The
Regional Vehicle Agreement contemplates that AT&T Latin America will serve as
AT&T's strategic vehicle in the countries of South America (excluding Venezuela)
and the Caribbean (excluding Cuba) for the provision of broadband high-speed
connectivity to business customers, and certain other telecommunications
services, upon the terms and conditions of the agreement. A copy of the Regional
Vehicle Agreement is

                                       2

attached as an exhibit to the Merger Agreement and is being filed herewith. The
services to be provided by AT&T Latin America will be provided under the "AT&T"
brand name, pursuant to the terms and conditions of a Service Mark License
Agreement, a copy of which is attached as an exhibit to the Merger Agreement and
is being filed herewith.

         The closing of the Merger Agreement is subject to certain conditions,
including the completion of the Netstream acquisition, the contribution by the
stockholders of AT&T Latin America (other than the stockholders of FirstCom) to
AT&T Latin America of not less than $70 million in cash equity and the provision
by AT&T of a $100 million revolving credit facility to AT&T Latin America and,
if requested by AT&T, the successful completion of a tender offer for FirstCom's
14% Senior Notes due 2007. Further, the Merger is subject to the approval of the
Merger by FirstCom's shareholders and certain regulatory approvals, including
those required under the Hart-Scott Rodino Antitrust Improvement Act of 1976, as
amended.

         Certain shareholders of FirstCom have agreed to vote in favor of the
Merger, upon the terms and subject to the conditions of voting agreements,
copies of which are being filed herewith.

         Copies of the Merger Agreement and the exhibits thereto are attached
hereto as Exhibits 2.1 through 2 9. A copy of the joint press release announcing
the Merger issued by FirstCom and AT&T on November 1, 1999 is attached hereto as
