Gentlemen:

         Reference is made to that certain Employment Agreement effective as of
November 1, 1999 by and between PF.Net Corp., a Delaware corporation (the
"Company"), and John Warta, and to that certain Employment Agreement effective
as of November 1, 1999 by and between the Company and Steve Irwin (collectively,
the "Employment Agreements"). As we have discussed and agreed, pursuant to
Section 1.2 of each of the Employment Agreements, a majority of the Board of
Directors of the Company may, in its sole discretion, modify the employment
duties of each of Messrs. Warta and Irwin, respectively, in such manner as it
deems appropriate. As we have further discussed and agreed, a majority of the
Board of Directors of the
<PAGE>

Company has determined to so modify the duties of each of Messrs. Warta and
Irwin in the manner set forth below.

         On and following the date hereof, unless expressly directed by either
the Chairman of the Board of Directors or a majority of the Board of Directors
of the Company in writing, each of Messrs. Warta and Irwin agrees that he will
engage only in activities typically performed by other directors of the Company.
Without limiting the foregoing, each of Messrs. Warta and Irwin agrees that he
will not (1) engage in activities relating to capital raising or change of
control transactions on behalf of, or in connection with, the Company or any of
its affiliates, or (2) make any public statement, issue any press release or
otherwise publicly convey information related to the Company. The Company
acknowledges that, except as may expressly be authorized by the Board of
Directors from time to time, no individual director of the Company is authorized
to engage in the foregoing activities. For purposes of the foregoing,
"affiliate" shall have the meaning set forth in Rule 405 of the Securities Act
of 1933, as amended.

         Notwithstanding the foregoing, the compensation and benefits for which
Messrs. Warta and Irwin are eligible under the terms of their respective
Employment Agreements shall not be reduced.

         Reference is also made to that certain Stockholders Agreement (the
"Stockholders Agreement") entered into as of October 29, 1999 by and among
PF.Net Communications, Inc., formerly known as PF.Net Holdings, Limited ("PF.Net
Communications"), John Warta, Karen Irwin, Treg Ventures, LLC, Koch Telecom
Ventures, Inc. ("Koch"), PF Telecom Holdings, LLC ("PF Telecom"), GLW Ventures
LLC, Georgiana Warta, Odyssey Coinvestors, LLC, Odyssey Investment Partners
Fund, LP ("Odyssey"), UBS Capital II LLC, UBS Warburg, LLC (formerly known as
Warburg Dillon Reed LLC), Credit Suisse First Boston and Lucent Technologies
Inc., as amended through the date hereof. On and following the date hereof, PF
Telecom, Koch and Odyssey each agrees to waive any and all of its rights under
Section 4(a)(vi) of the Stockholders Agreement to require the PF Telecom
Directors, the Koch Directors and the Odyssey Directors (each as defined in the
Stockholders Agreement), respectively, each voting as a group, to approve any
transaction relating to the employment or termination of any member of senior
management of PF.Net Communications or any of its Subsidiaries (as defined in
the Stockholders Agreement). Each of PF Telecom, Koch and Odyssey further agrees
that the employment or termination of any member of senior management of PF.Net
Communications or any of its Subsidiaries, other than any relative or Affiliate
of any PF Telecom Holder (each as defined in the Stockholders Agreement), will
require the approval of a majority of the Board of Directors, without regard to
whether such action has been approved by any one or more members of any of the
aforementioned groups. The foregoing shall not affect the parties' rights and
obligations under Section 4(d) of the Stockholders Agreement.

         This letter will constitute an amendment to each of the Employment
Agreements and to the Stockholders Agreement.
