ITEMS 1-4.     NOT APPLICABLE

ITEM 5.   OTHER EVENTS.
          ------------ 

     On December 16, 1998, the Board of Directors of Primus Telecommunications
Group, Incorporated, a Delaware corporation (the "Company"), declared a
                                                  -------              
distribution of one Right (as defined below) for each outstanding share of
Common Stock, par value $.01 per share (the "Company Common Stock"), to
                                             --------------------      
stockholders of record at the close of business on December 31, 1998 (the
                                                                         
"Record Date") and for each share of Company Common Stock issued (including
- ------------                                                               
shares distributed from Treasury) by the Company thereafter and prior to the
Distribution Date.  Each Right entitles the registered holder, subject to the
terms of the Rights Agreement, to purchase from the Company one one-thousandth
of a share (a "Unit") of Series B Junior Participating Preferred Stock, par
               ----                                                        
value $.01 per share (the "Preferred Stock"), at a Purchase Price of $90.00 per
                           ---------------                                     
Unit, subject to adjustment (the "Right").  The Purchase Price is payable in
                                  -----                                     
cash or by certified or bank check or money order payable to the order of the
Company.  The description and terms of the Rights are set forth in a Rights
Agreement between the Company and StockTrans, Inc., as Rights Agent (the "Rights
                                                                          ------
Agreement").
- ---------   

     Initially, the Rights will attach to all certificates representing shares
of outstanding Company Common Stock, and no separate Rights Certificates will be
distributed.  The Rights will separate from the Company Common Stock and the
"Distribution Date" will occur (i) upon the earlier of (x) 10 business days
following a public announcement (the date of such announcement being the "Stock
                                                                          -----
Acquisition Date") that a person or group of affiliated or associated persons
- ----------------                                                             
(other than the Company, any subsidiary of the Company or any employee benefit
plan of the Company or such subsidiary) (an "Acquiring Person") has acquired,
                                             ----------------                
obtained the right to acquire, or otherwise obtained beneficial ownership of 20%
or more of the then outstanding shares of Company Common Stock, and (y) 10
business days following the commencement of a tender offer or exchange offer
that would result in an Acquiring Person owning 20% or more of the then
outstanding shares of Company Common Stock, or (ii) such later date as may be
determined by action of a majority of the members of the Board of Directors
(such determination to be made prior to such time as any person becomes an
Acquiring Person pursuant to (x) or (y) above).  Until the Distribution Date,
(i) the Rights will be evidenced by Company Common Stock certificates and will
be transferred with and only with such Company Common Stock certificates, (ii)
new Company Common Stock certificates issued after the Record Date (also
including shares distributed from Treasury) will contain a notation
incorporating the Rights Agreement by reference and (iii) the surrender for
transfer of any certificates representing outstanding Company Common Stock will
also constitute the transfer of the Rights associated with the Company Common
Stock represented by such certificates.

     The Rights are not exercisable until the Distribution Date and will expire
at the close of business on the tenth anniversary of the Rights Agreement unless
earlier redeemed by the Company as described below.

     As soon as practicable after the Distribution Date, Rights Certificates
will be mailed to holders of record of Company Common Stock as of the close of
business on the Distribution Date and, thereafter, the separate Rights
Certificates alone will represent the Rights.

     In the event that (i) the Company is the surviving corporation in a merger
with an Acquiring Person and shares of Company Common Stock shall remain
outstanding, (ii) a Person becomes the beneficial owner of 20% or more of the
then outstanding shares of Company Common Stock, (iii) an Acquiring Person
engages in one or more "self-dealing" transactions as set forth in the Rights
Agreement, or (iv) during such time as there is an Acquiring Person, an event
occurs which results in such Acquiring Person's ownership interest being
increased by more than 1% (e.g., by means of a reverse stock split or
                           ----                                      
recapitalization), then, in each such case, each holder of a Right will
                   ----                                                
thereafter have the right to receive, upon exercise, Units of Preferred Stock
(or, in certain circumstances, Company Common Stock, cash, property or other
securities of the Company) having 

                                       2

 
a value equal to two times the exercise price of the Right. The exercise price
is the Purchase Price multiplied by the number of Units of Preferred Stock
issuable upon exercise of a Right prior to the events described in this
paragraph. Notwithstanding any of the foregoing, following the occurrence of any
of the events set forth in this paragraph, all Rights that are, or (under
certain circumstances specified in the Rights Agreement) were, beneficially
owned by any Acquiring Person will be null and void.

     In the event that, at any time following the Stock Acquisition Date, (i)
the Company is acquired in a merger or other business combination transaction
and the Company is not the surviving corporation (other than a merger described
in the preceding paragraph), (ii) any Person consolidates or merges with the
Company and all or part of the Company Common Stock is converted or exchanged
for securities, cash or property of any other Person or (iii) 50% or more of the
Company's assets or earning power is sold or transferred, each holder of a Right
(except Rights which previously have been voided as described above) shall
thereafter have the right to receive, upon exercise, common stock of the
Acquiring Person having a value equal to two times the exercise price of the
Right.

     The Purchase Price payable, and the number of Units of Preferred Stock
issuable, upon exercise of the Rights are subject to adjustment from time to
time to prevent dilution (i) in the event of a stock dividend on, or a
subdivision, combination or reclassification of, the Preferred Stock, (ii) if
holders of the Preferred Stock are granted certain rights or warrants to
subscribe for Preferred Stock or convertible securities at less than the current
market price of the Preferred Stock, or (iii) upon the distribution to the
holders of the Preferred Stock of evidences of indebtedness, cash or assets
(excluding regular quarterly cash dividends) or of subscription rights or
warrants (other than those referred to above).

     With certain exceptions, no adjustment in the Purchase Price will be
required until cumulative adjustments amount to at least 1% of the Purchase
Price.  The Company is not required to issue fractional Units.  In lieu thereof,
an adjustment in cash may be made based on the market price of the Preferred
Stock prior to the date of exercise.

     At any time until (i) ten business days following the Stock Acquisition
Date or (ii) such later date as a majority of the members of the Board of
Directors shall determine (such determination to be made prior to the date
specified in (i) above), a majority of the Board of Directors may redeem the
Rights in whole, but not in part, at a price of $.001 per Right (subject to
adjustment in certain events) (the "Redemption Price"), payable, at the election
                                    ----------------                            
of such majority of the Board of Directors, in cash or shares of Company Common
Stock.  Immediately upon the action of a majority of the Board of Directors
ordering the redemption of the Rights, the Rights will terminate and the only
right of the holders of Rights will be to receive the Redemption Price.

     Until a Right is exercised, the holder thereof, as such, will have no
rights as a stockholder of the Company, including, without limitation, the right
to vote or to receive dividends.  While the distribution of the Rights will not
be taxable to stockholders or to the Company, stockholders may, depending upon
the circumstances, recognize taxable income in the event that the Rights become
exercisable for Units of Preferred Stock (or other consideration).

     Any of the provisions of the Rights Agreement may be amended by the Board
of Directors without the approval of the holders of Company Common Stock at any
time prior to the Distribution Date.  After the Distribution Date, the
provisions of the Rights Agreement may be amended in order to cure any
ambiguity, defect or inconsistency, to make changes which do not adversely
affect the interests of holders of Rights (excluding the interests of any
Acquiring Person), or to shorten or lengthen any time period under the Rights
Agreement; provided, however, that no amendment to adjust the time period
           --------  -------                                             
governing redemption shall be made at such time as the Rights are not
redeemable.

                                       3

 
     The Units of Preferred Stock that may be acquired upon exercise of the
Rights will be nonredeemable and subordinate to any other shares of preferred
stock that may be issued by the Company.

     Each Unit of Preferred Stock will be entitled to dividends at the same rate
per share as dividends declared on the Company Common Stock and shall be
entitled to payment of dividends to the extent dividends are declared on the
Company Common Stock.  In the event of liquidation, the holder of a Unit of
Preferred Stock will receive the per share amount paid in respect of a share of
Company Common Stock.

     In the event of any merger, consolidation or other transaction in which
shares of Company Common Stock are exchanged, each Unit of Preferred Stock will
be entitled to receive the per share amount paid in respect of each share of
Company Common Stock.  Each Unit of Preferred Stock will have one vote, voting
together with the Company Common Stock.  The rights of holders of the Preferred
Stock to dividends, liquidation and voting, and in the event of mergers and
consolidations, are protected by customary antidilution provisions.

     Because of the nature of the Preferred Stock's dividend, liquidation and
voting rights, the economic value of one Unit of Preferred Stock that may be
acquired upon the exercise of each Right should approximate the economic value
of one share of the Company Common Stock.

     The form of Rights Agreement between the Company and the Rights Agent
specifying the term of the Rights, which includes as (i) Exhibit A, the Form of
Rights Certificate, and (ii) Exhibit B, the Form of Summary of Rights, is
attached hereto as Exhibit 4 and is incorporated herein by reference. The
foregoing description of the Rights does not purport to be complete and is
qualified in its entirety by reference to such Exhibit.

                        PRIMUS TELECOMMUNICATIONS GROUP
                         ADOPTS STOCKHOLDER RIGHTS PLAN

McLean, Va., Dec. 29 -- Primus Telecommunications Group, Incorporated (Nasdaq:
PRTL) today announced it has adopted a Stockholder Rights Plan (the "Plan") in
which preferred stock purchase rights have been granted as a dividend to the
Company's stockholders of record at the close of business on December 31, 1998.

Adoption of the Plan reflects the commitment of the Board of Directors to
Primus' business strategy and expansion plan by providing a means to better
protect stockholders' interests as that strategy and plan are pursued. The Plan,
which is similar to plans adopted by many other publicly-traded companies, is
designed to deter coercive or unfair takeover tactics. The Company's adoption of
the Plan was not adopted in response to any acquisition proposal. The Plan will
assist the Board of Directors in dealing with any future potential acquirers
that attempt to deprive the Company and its stockholders of the opportunity to
obtain the most attractive price for their shares.

In implementing the Plan, the Board has declared a distribution of one Right (a
"Right") for each outstanding share of the Company's Common Stock. Each Right
entitles the holder, subject to the terms of a Rights Agreement, to purchase
from the Company one one-thousandth of a share of Series B Junior Participating
Preferred Stock (the "Preferred Stock") at a Purchase Price of $90 per Right,
subject to adjustment. One one-thousandth of a share of Preferred Stock is
intended to be approximately the economic equivalent of one share of Common
Stock. The Rights will expire on December 23, 2008 unless redeemed by the
Company as described below.

At the time of adoption of the Plan, the Rights are neither exercisable nor
traded separately from the Common Stock. The Rights will become exercisable if a
person or group in the future becomes the beneficial owner of 20% or more of the
then outstanding Common Stock or announces an offer to acquire 20% or more of
the then outstanding Common Stock.

In the event that (i) the Company is the surviving corporation in a merger with
an acquiring person and shares of Company Common Stock shall remain outstanding,
(ii) a person becomes the beneficial owner of 20% or more of the then
outstanding shares of Company Common Stock, (iii) an acquiring person engages in
one or more "self-dealing" transactions as set forth in the Rights Agreement, or
(iv) during such time as there is an acquiring person, an event occurs which
results in such acquiring person's ownership interest being increased by more
than 1% (e.g., by means of a reverse stock split or recapitalization), each
holder of a Right (other than those held by an acquiring person) will thereafter
have the right to receive, upon exercise, Preferred Stock (or, in certain
circumstances, Company Common Stock, cash, property or other securities of the
Company) having a current market value equal to two times the exercise price of
the Right.

In the event that (i) the Company is acquired in a merger or other business
combination transaction and the Company is not the surviving corporation (other
than a merger described in the preceding paragraph), (ii) any person
consolidates or merges with the Company and all or part of the Company Common
Stock is converted or exchanged for securities, cash or property of any other
person or (iii) 50% or more of the Company's assets or earning power is sold or
transferred, each holder of a Right (other than those held by an acquiring
person) shall thereafter have the right to receive, upon exercise, common stock
of the acquiring person having a value equal to two times the exercise price of
the Right.

The Board of Directors may redeem the Rights in whole, but not in part, at a
price of $.001 per Right (subject to adjustment in certain events) (the
"Redemption Price"), payable, at the election of the Board of Directors, in cash
or shares of Company Common Stock. Immediately upon the action of the Board of
Directors ordering the redemption of the Rights, the Rights will terminate and
the only right of the holders of Rights will be to receive the Redemption Price.
Details of the Plan will be mailed to all stockholders of the Company.
