ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS


Effective June 20, 2000, Cowboy Acquisition Corp., a Delaware corporation
("Merger Sub") and a wholly owned subsidiary of InterNAP Network Services
Corporation, a Washington corporation ("Parent"), was merged (the "Merger")
with and into CO Space, Inc., a Delaware corporation (the "Company"),
pursuant to an Agreement and Plan of Merger and Reorganization (the
"Reorganization Agreement"), dated May 26, 2000, among Parent, Merger Sub and
the Company. The description contained in this Item 2 of the transactions
consummated pursuant to the terms and conditions of the Reorganization
Agreement is qualified in its entirety by reference to the full text of the
Reorganization Agreement, a copy of which is attached to this Report as
Exhibit 2.1.

Pursuant to the Merger, each then-outstanding share of common stock ($.01 par
value) of the Company (including all shares of common stock of the Company
issued upon conversion of the Company's preferred stock and upon exercise of
company warrants immediately prior to the effective time of the Merger) was
converted into the right to receive 0.24488 (the "Applicable Fraction") of a
share of common stock of Parent ("Parent Common Stock").

Approximately 6,881,017 shares of Parent Common Stock and an aggregate
$200,000 in cash will be issued to the former stockholders of the Company in
the Merger. In addition, Parent assumed all Company outstanding options to
acquire Company common stock which are exercisable for 322,837 shares of
Parent common stock. No fractional shares of Parent common stock will be
issued in connection with the Merger. In lieu thereof, any holder of Company
common stock who would otherwise have been entitled to receive fractional
shares of the Parent common stock will be paid an amount based on the value
of such fractional shares multiplied by $34.54375 (rounded to the nearest
whole cent) without interest. At the Effective Time (as defined in the
Reorganization Agreement), Merger Sub ceased to exist and the Company, as the
surviving corporation in the Merger, became a wholly-owned subsidiary of the
Parent. The Merger was intended to qualify as a tax-free reorganization under
the Internal Revenue Code of 1986, as amended, and was  to be accounted for
on a purchase basis. The Company, a leading co-location service provider,
provides technology, intellectual property, personnel and a customer base,
which gives Parent the ability to accelerate the delivery of its high
performance IP connectivity service to those customers with co-location
requirements.

The Merger Agreement and the press releases issued in connection with the
signing and closing of this acquisition are filed as Exhibits 2.1, 99.1 and
99.2, respectively, to this report and are incorporated herein by reference.
