                        VERTICALNET EXTENDS TENDER OFFER
                 FOR SIERRACITIES.COM INC. TO DECEMBER 29, 2000

HORSHAM, PA, December 15, 2000 -- VerticalNet, Inc. (Nasdaq: VERT) announced
today that Truckee Acquisition Co., a wholly-owned subsidiary of VerticalNet, is
extending its offer to acquire all outstanding shares of common stock of
SierraCities.com Inc. (Nasdaq: BTOB) until midnight, New York City time, on
Friday, December 29, 2000.  The offer was previously scheduled to expire at
midnight on Thursday, December 14, 2000.

Based on the latest count of tendered shares, approximately 12,674,851 shares of
SierraCities common stock, representing less than two thirds of all outstanding
SierraCities common stock on a fully diluted basis, have been tendered and not
withdrawn pursuant to the exchange offer.

As a consequence of the extension of the expiration date, holders of
SierraCities common stock may tender or withdraw shares until midnight, New York
City time, Friday, December 29, 2000, unless the offer is further extended.

The extension will provide SierraCities stockholders additional time to tender
shares so that the minimum condition of at least two thirds of the outstanding
shares of SierraCities common stock on a fully diluted basis being validly
tendered and not withdrawn prior to the expiration of the offer may be
satisfied. The extension will provide VerticalNet additional time to obtain a
declaration of effectiveness from the Securities and Exchange Commission with
respect to VerticalNet's registration statement relating to shares to be issued
by VerticalNet in the offer.

VerticalNet also announced that, on December 6, 2000, the US antitrust
authorities granted the request of VerticalNet and SierraCities for early
termination of the 30-day waiting period with respect to the exchange offer.
