                          INDEPENDENT AUDITOR'S REPORT


To the Trustees and Participants
Primus Telecommunications Group, Inc. 401(k) Plan
McLean, Virginia

We have audited the accompanying statement of net assets available for benefits
of Primus Telecommunications Group, Inc. 401(k) Plan (the Plan) as of December
31, 2000, and the related statement of changes in net assets available for
benefits for the year ended December 31, 2000. These financial statements are
the responsibility of the Plan's management. Our responsibility is to express an
opinion on these financial statements based on our audit. Other auditors were
engaged to audit, before the matters discussed in Note 8, the statement of net
assets available for benefits of Primus Telecommunications Group, Inc. 401(k)
Plan as of December 31, 1999. Their report dated October 31, 2000, disclaimed an
opinion on the 1999 statement as permitted by 29 CFR 2520.103-8 of the
Department of Labor's (DOL) Rules and Regulations for Reporting and Disclosure
under the Employee Retirement Income Security Act of 1974 (ERISA).

We conducted our audit in accordance with auditing standards generally accepted
in the United States of America. Those standards require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audit provides a
reasonable basis for our opinion.

In our opinion, the financial statements referred to above, present fairly, in
all material respects the net assets available for benefits of the Plan as of
December 31, 2000, and the changes in net assets available for benefits for the
year ended December 31, 2000, in conformity with accounting principles generally
accepted in the United States of America.

As described in Note 8 to the financial statements, the Plan changed its method
of accounting from the modified cash basis to the accrual basis of accounting.

We also audited the adjustments in Note 8 that were applied to restate the
December 31, 1999, financial statements. In our opinion, such adjustments are
appropriate and have been applied properly.




                                       1







Our audit was performed for the purpose of forming an opinion on the basic
financial statements taken as a whole. The supplemental schedules of assets held
for investment purposes at the end of the year and nonexempt transactions are
presented for the purpose of additional analysis and are not a required part of
the basic financial statements but are supplementary information required by the
DOL's Rules and Regulations for Reporting and Disclosure under ERISA. These
supplemental schedules are the responsibility of the Plan's management. The
supplemental schedules have been subjected to the auditing procedures applied in
the audit of the basic financial statements and, in our opinion, are fairly
stated in all material respects in relation to the basic financial statements
taken as a whole.

The schedule of assets held for investment purposes at the end of the year that
accompanies the Plan's financial statements does not disclose the historical
cost of certain nonparticipant directed plan assets held by the Plan trustee.
Disclosure of this information is required by the DOL's Rules and Regulations
for Reporting and Disclosure under the ERISA.

PRIMUS TELECOMMUNICATIONS GROUP, INC. 401(k) PLAN

NOTES TO FINANCIAL STATEMENTS
--------------------------------------------------------------------------------

NOTE 1. PLAN DESCRIPTION AND SIGNIFICANT ACCOUNTING POLICIES

PLAN DESCRIPTION: The following description of Primus Telecommunications Group,
Inc. 401(k) Plan (the Plan) provides only general information. Participants
should refer to the plan agreement for a more complete description of the Plan's
provisions.

GENERAL: The Plan is a defined contribution plan covering all employees, except
nonresident aliens, of Primus Telecommunications Group, Inc. and LCR Telecom
(the Company) who are 21 years old. Full time employees must have completed 1/4
year of service and part-time employees must have completed one year of service
to be eligible. It is subject to the provisions of the ERISA.

CONTRIBUTIONS: Each year, participants may elect to make salary reduction
contributions of up to 20% of pretax annual compensation, as defined in the
Plan. Participants may also contribute amounts representing distributions from
other qualified defined benefit or defined contribution plans. Participants
direct the investment of their contributions into various investment options
offered by the Plan. The Plan currently offers 9 mutual funds, a common
collective trust account, and the Company's common stock. The participants may
change their investment allocations daily. The Company contributes 50% of the
first 6% of base compensation that a participant contributes to the Plan. The
matching Company contribution is invested directly in Primus Telecommunications
Group, Inc. common stock. Additional profit sharing accounts may be contributed
at the option of the Company's board of directors. For the year ended December
31, 2000, no discretionary contributions were made. Contributions are subject to
certain limitations.

PARTICIPANT ACCOUNTS: Each participant's account is credited with the
participant's contributions and allocations of (a) the Company's contribution
and, (b) Plan earnings/losses and charged with an allocation of administrative
expenses. Allocations are based on participant earnings or account balances, as
defined. The benefit to which a participant is entitled is the benefit that can
be provided from the participant's vested account.

VESTING: Participants are immediately vested in their contributions plus actual
earnings thereon. Vesting in the Company's contribution portion of their
accounts is based on years of continuous services. A participant is 100% vested
after three years of credited service.

PARTICIPANT LOANS: Participants may borrow from their fund accounts a minimum of
$1,000 up to a maximum of $50,000 or 50% of their account balance, whichever is
less. The loans are secured by the balance in the participant's account and bear
interest at rates of prime plus 1% set at the time the loan is taken. The Prime
rate at December 31, 2000, was 9.5%. Principal and interest payments are made
through bi-weekly payroll deductions and applied to the loan balances once a
month.

PAYMENT OF BENEFITS: On termination of service due to disability retirement or
death and the total benefit is greater than $3,500, a participant or his or her
beneficiary may elect to receive either a lump-sum amount equal to the
participant's vested interest in his or her account or leave their account in
the Plan. If the total benefit is $3,500 or less, the entire amounts is to be
paid in a lump-sum distribution.

PRIMUS TELECOMMUNICATIONS GROUP, INC. 401(k) PLAN

NOTES TO FINANCIAL STATEMENTS
--------------------------------------------------------------------------------

NOTE 1. PLAN DESCRIPTION AND SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

FORFEITED ACCOUNTS: At December 31, 2000, forfeited nonvested accounts totaled
$42,660. These accounts will be used to reduce future employer contributions.
During 2000, employer contributions were not reduced by any forfeited nonvested
accounts.

A summary of the Plan's significant accounting policies follows:

ESTIMATES: The preparation of financial statements requires management to make
estimates and assumptions that affect the reported amounts of assets,
liabilities, and changes therein, and disclosure of contingent assets and
liabilities. Actual results could differ from those estimates.

INVESTMENT VALUATION AND INCOME RECOGNITION: Investment in pooled separate
accounts are recorded at fair value, as determined by the unit value reported by
Merrill Lynch. Participant loans are valued at cost, which approximates fair
value. The common stock of the Company is value at market value.

The Plan invests in a common/collective trust account and mutual funds. Such
investments are exposed to various risks such as market and credit. Due to the
level of risk associated with such investments and the level of uncertainty
related to changes in the value of such investments, it is at least reasonably
possible that changes in risks in the near term would materially affect
investment balances and the amounts reported in the financial statements.

Purchases and sales of securities are recorded on a trade-date basis. Interest
income is recorded on the accrual basis. Dividends are reported on the
ex-dividend date.

PAYMENT OF BENEFITS:  Benefits are recorded when paid.

NOTE 4. PLAN TERMINATION

Although it has not expressed any intent to do so, the Company has the right
under the Plan to discontinue its contributions ay any time and to terminate the
Plan subject to the provisions of ERISA. In the event of Plan termination,
participants will become 100% vested in their accounts.

plan received a determination letter from the Internal Revenue Service (IRS)
dated June 29, 1993, stating that the prototype plan document as designed
qualified under the provisions of Section 401(a) of the Internal Revenue Code
(IRC). The Plan has been amended since adopting the prototype plan, however, the
plan administrator believes that the Plan is designed and is currently being
operated in compliance with the applicable requirements of the IRC.


NOTE 6. RELATED PARTY TRANSACTIONS

Certain plan investments are units of pooled separate accounts managed by
Merrill Lynch Trust Company, FSB (ML). ML is the trustee as defined by the Plan

NOTE 8. CHANGE IN METHOD OF ACCOUNTING

During 2000, the Plan changed its method of accounting from the modified cash
basis to the accrual basis of accounting. Consequently, the 1999 statement of
net assets available for benefits was restated to report the statement on the
accrual basis of accounting in conformity with accounting principles generally
accepted in the United States of America. Receivables for participant and
employer contributions, as of December 31, 1999, were recorded in the amounts of
$78,709 and $25,011, respectively, to report the statement of net assets
available for benefits on the accrual basis of accounting in conformity with
accounting principles generally accepted in the United States of America. The
cumulative effect of this adjustment was to restate net assets available for
benefits at December 31, 1999, by an increase of $103,720.


NOTE 9. SUBSEQUENT EVENT

The Company is in the process of amending and restating the Plan to comply with
recent legislative changes.
