                                   ----------


In accordance with Securities and Exchange Commission Release No. 34-39538
(January 12, 1998), this Schedule 13G is being filed by Credit Suisse First
Boston (the "Bank"), a Swiss bank, on behalf of itself and its subsidiaries, to
the extent that they constitute the Credit Suisse First Boston business unit
(the "CSFB business unit") excluding Asset Management (as defined below) (the
"Reporting Person"). The CSFB business unit is also comprised of an asset
management business principally conducted under the brand name Credit Suisse
Asset Management ("Asset Management"). The Reporting Person provides financial
advisory and capital raising services, sales and trading for users and suppliers
of capital around the world and invests in and manages private equity and
venture capital funds. Asset Management provides asset management and investment
advisory services to institutional, mutual fund and private investors worldwide.
The address of the Bank's principal business and office is Uetlibergstrasse 231,
P.O. Box 900, CH 8070 Zurich, Switzerland. The address of the Reporting Person's
principal business and office in the United States is Eleven Madison Avenue, New
York, New York 10010.

The ultimate parent company of the Bank is Credit Suisse Group ("CSG"), a
corporation formed under the laws of Switzerland. CSG is a global financial
services company with two distinct business units. In addition to the CSFB
business unit, CSG and its consolidated subsidiaries are comprised of the Credit
Suisse Financial Services business unit (the "Credit Suisse Financial Services
business unit"). CSG's business address is Paradeplatz 8, P.O. Box 1, CH 8070
Zurich, Switzerland.

CSG, for purposes of the federal securities laws, may be deemed ultimately to
control the Bank and the Reporting Person. CSG, its executive officers and
directors, and its direct and indirect subsidiaries (including Asset Management
and the Credit Suisse Financial Services business unit) may beneficially own
shares of the securities of the issuer to which this schedule relates (the
"Shares") and such Shares are not reported in this statement. CSG disclaims
beneficial ownership of Shares beneficially owned by its direct and indirect
subsidiaries, including the Reporting Person. The Reporting Person disclaims
beneficial ownership of Shares beneficially owned by CSG, Asset Management and
the Credit Suisse Financial Services business unit.

The Reporting Person, along with certain individuals and corporations, may be
deemed to be a group with respect to the securities of Nextel Partners, Inc. as
a result of being parties to the Amended and Restated Shareholders' Agreement,
dated February 18, 2000, as amended on February 22, 2000 (the "Shareholders
Agreement"). The Reporting Person disclaims beneficial ownership of any Nextel
Partners, Inc. securities held by any other party to the Shareholders Agreement.
