Item 5.  Other Events.

Investment by Forstmann Little
- ------------------------------

On December 7, 1999, NEXTLINK Communications, Inc. ("NEXTLINK") entered into an
agreement with affiliates of Forstmann Little & Co. under which Forstmann Little
would invest $850 million to be used to expand NEXTLINK's networks and services,
introduce new technologies and fund NEXTLINK's business plan.

Forstmann Little will invest approximately $850 million in NEXTLINK in the form
of convertible preferred stock with a conversion price of $63.25 per share and a
3.75 percent dividend. Under the agreement, Forstmann Little may convert to and
transfer the common stock after one year, and NEXTLINK may call the preferred
stock after five years. Forstmann Little will also have the option of requiring
redemption of the preferred stock after 10 years. The investment represents
ownership of approximately 8 percent of NEXTLINK's fully diluted common shares.
The transaction is subject to certain conditions and is expected to close in
early 2000. Nicholas C. Forstmann and Sandra J. Horbach, both general partners
at Forstmann Little, will join the NEXTLINK Board of Directors.

The stock purchase agreement (including the certificates of designation for the
convertible preferred stock), filed herewith as Exhibit 99.1, and NEXTLINK's
press release announcing the agreement, filed herewith as Exhibit 99.2, are
incorporated herein by reference.

Purchase of INTERNEXT Interests
- -------------------------------

On December 7, 1999, NEXTLINK announced that it had agreed to acquire Eagle
River Investments' 50 percent ownership interest in INTERNEXT LLC for $220
million of NEXTLINK common stock, representing approximately 4.1 million shares,
based on NEXTLINK's common stock closing sale price of $53.50 on December 6,
1999.

The actual number of shares of NEXTLINK common stock to be issued is subject to
adjustment in the event that the average price of the NEXTLINK common stock at
the time of the closing of the transaction is more than $64.20, in which case
Eagle River will receive approximately 3.4 million shares, or less than $42.80,
in which case Eagle River will receive approximately 5.1 million shares.

Both the NEXTLINK Board and Eagle River Managers have approved the transaction.
The transaction, which is expected to close in early 2000, is subject to a
number of conditions including the negotiation of definitive transaction
agreements and the receipt of necessary approvals.

NEXTLINK's press release announcing the agreement with Eagle River, filed
herewith as Exhibit 99.3, is incorporated herein by reference.

Joint Venture for Canadian Wireless Spectrum
- --------------------------------------------

On December 9, 1999, NEXTLINK International, Inc., a NEXTLINK subsidiary,
entered into a shareholder's agreement with Wispra Networks, Inc., a broadband
wireless venture in Canada. The other participants in the venture are Wispra
Inc., a long-time participant in Canada's broadband wireless marketplace, and TD
Capital Group, a leading Canadian private equity investor in the communications
and media industry.

This new venture was made in connection with the submission by Wispra Networks
of its completed broadband wireless 24/38 GHz spectrum license documents and
initial license payment to Industry Canada following being named provisional
winner of six fixed broadband wireless licenses. The licenses cover 14.3 million
population in Toronto, Montreal, Vancouver, Ottawa, Edmonton, Calgary and
surrounding areas. Wispra Networks will pay a total of $50.1 million ($74
million in Canadian dollars) for 400 MHz of spectrum in the six market areas.
Wispra Networks anticipates the filing of the license documents and payments of
the balance license fee will result in Industry Canada officially issuing
licenses for the spectrum early next year.

Wispra Network's press release announcing the venture, filed herewith as Exhibit
99.4, is incorporated herein by reference.
