                                     Primus

   We are a facilities-based global telecommunications company. We offer
international and domestic long distance, and other telecommunications services
to business, residential and carrier customers located in North America and
Europe and selected markets in the Asia-Pacific region. We seek to capitalize
on the increasing demand for high-quality international telecommunications
services which is being driven by the globalization of the world's economies,
the worldwide trend toward telecommunications deregulation and the growth of
global data and Internet traffic.

   We are a full-service carrier with operations in the United States, Canada,
Australia, the United Kingdom, Germany, France, Switzerland, the Netherlands,
Denmark, Italy, Japan and Hong Kong. We had net revenue and pro forma net
revenue, after giving effect to our merger with TresCom International, Inc. and
our acquisition of the global retail telecommunications business of Telegroup,
Inc., including the acquisition of selected Telegroup foreign subsidiaries, as
follows:

</TABLE>

   We primarily target customers with significant international long distance
usage, including small- and medium-sized businesses, multinational
corporations, ethnic residential customers and other telecommunications
carriers and resellers. Through our newly formed subsidiary, iPrimus.com, we
are also beginning to target business and residential customers for data and
Internet services. We provide our approximately 1.7 million customers with
competitively priced services, including:
     .international and domestic long distance services and private networks;

     .prepaid and calling cards, toll-free services and reorigination
  services;

     .local services in Australia, Canada, Puerto Rico and the United States
  Virgin Islands;
     .data, Internet and cellular services in Australia; and

     .Internet services in Canada and Germany.

   In an effort to attract larger business customers in multiple markets, we
intend to offer a broad array of services (including long distance voice,
cellular, Internet and data services) in approximately 10 major markets,
including the United States, Canada, Australia, the United Kingdom, Germany,
France, Japan and Italy. We market our services through a variety of channels,
including through our direct sales force, independent agents and direct
marketing.

                           Our Business Strategy

   Our objective is to become a leading global provider of international and
domestic long distance voice, Internet, data and other services in our
principal service regions. Key elements of our strategy to achieve this
objective include the following:

     .Focus on customers with significant international long distance usage;

     .Pursue early entry into selected deregulating markets;

     .Expand our global network;

     .Provide a full portfolio of voice, data and Internet services;

     .Provide transmission for Internet and data services in developing
  countries;

     .Broaden retail customer base; and

     .Grow through selected acquisitions, joint ventures and strategic
  investments.

                         Our Telecommunications Network

   We have been able to reduce our costs, improve our service reliability and
increase our flexibility to introduce new products and services by constructing
and expanding our telecommunications network. As a result, we increased our
gross margin as a percentage of net revenue (after accounting for bad debt) to
20.3% in the first quarter of 1999 from 6.8% in the first quarter of 1997. We
believe that we should continue to improve our profitability as the volume of
telecommunications traffic carried on our network increases and we realize
economies of scale. Currently, 24 countries are connected directly to our
network. We expect to continue to expand our network through additional
investment in undersea and domestic fiber optic cable systems, international
gateway and domestic switching facilities and international satellite earth
stations as customer demand justifies the capital investment.

   Our network consists of 19 carrier-grade switches including 15 international
gateway switches. All of our switches are capable of transmitting both voice
and data. We also have more than 100 points of presence (POPs) and Internet
access nodes within our principal service regions worldwide. Our international
gateway switches will serve as the base for the global expansion of our network
into new countries when customer demand justifies such investment and as
regulatory rules permit us to compete in new markets. We are currently
installing an international gateway switch in France, which is expected to be
operational during the second quarter of 1999. By the end of 2000, we intend to
add up to 11 additional switches in Europe, one switch in North America and one
switch in Japan.

   We own and lease transmission capacity, including interests in 23 undersea
fiber optic cable systems, which connects our switches to each other and to the
networks of other international and domestic telecommunications carriers. In
September 1998, we entered into an agreement to purchase $20 million of fiber
capacity from Qwest Communications International Inc., which will provide high
speed connections among our U.S. gateway switches and future POPs. We expect to
continue to acquire additional capacity on both existing and future
international and domestic fiber optic cable systems as demand justifies such
investments.

   We are constructing international satellite earth stations and purchasing
capacity on international satellites in order to provide data and Internet
transmission services, in addition to voice services, principally to and from
post, telephone and telegraph operators, other telecommunications carriers and
Internet service providers, in developing countries. We have completed the
construction of an Intelsat earth station in London and have reserved capacity
on the Intelsat-62(degrees) satellite. This earth station now is operational,
and is able to carry voice, data and Internet traffic to and from countries in
the Indian Ocean/Southeast Asia region, Eastern Africa and the Middle East.
Global Crossing has agreed to purchase up to $25 million of capacity on our
global satellite network. By the end of 1999, we expect to expand our global
satellite coverage by leasing a satellite earth station on each of the east and
west coasts of the United States and by reserving additional capacity on
international satellites. These additional facilities will position us to
provide voice, data and Internet transmission services to Latin America and the
Pacific Rim.

   We enter into foreign carrier agreements with incumbent carriers or other
service providers in a given country, permitting us to carry traffic into and
receive return traffic from those countries where competition with the
incumbent carriers is limited or prohibited.

                            Recent Developments

 Acquisition of Telegroup Retail Assets

   Effective June 1, 1999, we acquired the global retail business of Telegroup,
including the acquisition of selected Telegroup foreign subsidiaries, which
includes:

    . Telegroup's global retail business, which consists of approximately
      372,000 customers;

    . Two carrier-grade switches, one located in the New York City area and
      one located in London;

    . 14 switching platforms and POPs located in the United Kingdom,
      Germany, France, the Netherlands, Denmark, Switzerland, Italy, Japan
    and Hong Kong;

     .Telegroup's global network of sales agents;

    . A Web-based order-entry and provisioning system for agents; and

    . A global network operations center and call center.

   We expect that this acquisition will result in approximately $150 million of
sustainable retail revenues annually, after taking into account attrition in
Telegroup's customer base which began to occur prior to the Telegroup
acquisition and which we expect to continue for the near future.

 Acquisition of AT&T Canada Consumer Business

   In May 1999, we purchased the residential long distance customer base from
AT&T Canada and ACC Telenterprises. This acquisition included approximately
428,000 retail customers, customer support assets, including approximately
28,000 residential Internet customers, and related POPs. As part of the
acquisition, we entered into a strategic alliance with AT&T Canada whereby AT&T
Canada agreed to provide us with, among other things, network services in
Canada for five years as well as customer support services for 12 months. With
this acquisition, we believe we are now the second largest alternative long
distance carrier in Canada based on revenue.

 Global Crossing Reciprical Capacity Purchase Agreement

   In May 1999, we entered into a reciprocal capacity purchase agreement with
Global Crossing Holdings Ltd. Under this agreement, we agreed to purchase up to
$50 million of fiber capacity from Global Crossing, and Global Crossing agreed
to purchase up to $25 million of capacity on our global satellite network.

 Acquisition of London Telecom

   In March 1999, we acquired London Telecom and the assets of certain related
companies, which collectively provide domestic and international long distance
services to approximately 162,000 residential and business customers in Canada.


                                ----------------

   As of July 29, 1999, our equity market capitalization was $495,207,670,
based upon a closing price of $17.25 per share and 28,707,691 shares of Common
Stock outstanding.

   Our executive offices are located at 1700 Old Meadow Road, McLean, Virginia
22102, and our telephone number is (703) 902-2800.

                              notes from the date of original issuance or the
                              last interest payment date, to, but excluding,
                              the date of issuance of the new notes. Such
                              interest is payable with the first interest
                              payment on the new notes. Interest on the
                              unregistered notes accepted for exchange, which
                              accrues at the rate of 11 1/4% per annum, will
                              cease to accrue on the day prior to the issuance
                              of the new notes.

Federal Income Tax
 Considerations.............  The exchange pursuant to the exchange offer will
                              not be a taxable event for federal income tax
                              purposes.

                              for the exchange offer. The address and telephone

Resales of the Exchange
 Notes......................  Based on interpretations by the staff of the SEC
                              in no-action letters issued to third parties, we
                              believe that new notes issued pursuant to the
                              exchange offer to you in exchange for the
                              unregistered notes may be offered for resale,
                              resold and otherwise transferred by you without
                              compliance with the registration and prospectus
                              delivery provisions of the Securities Act,
                              provided that you are acquiring the new notes in
                              the ordinary course of business and are not
                              participating, and have no arrangement or
                              understanding with any person to participate, in
                              a distribution of the new notes. However, the
                              foregoing is not applicable to you if you are

                                (i) a broker-dealer who purchased the
                                    unregistered notes directly from us for

                                    Securities Act or any other available

                              notes, where such unregistered notes were
                              acquired by such broker as a result of market
                              making or other trading activities, must

                                 The New Notes

Issuer......................  Primus Telecommunications Group, Incorporated.

Notes Offered...............  $200 million in aggregate principal amount of 11
                              1/4% Senior Notes due 2009.

Maturity....................  January 15, 2009.

Interest Payment Dates......  January 15 and July 15; the first interest
                              payment date for the new notes is January 15,
                              2000. The first interest payment date for the
                              unregistered notes was July 15, 1999, and
                              interest was paid to the holders of the
                              unregistered on July 15, 1999.

Ranking.....................  The new notes will rank senior in right of
                              payment to all of our existing and future
                              obligations that are expressly subordinated in
                              right of payment to the new notes and will rank
                              pari passu in right of payment with all of our
                              other existing and future senior unsecured
                              obligations, including our trade payables. As of
                              March 31, 1999, after giving pro forma effect to
                              the offering of the new notes and our issuance of
                              $45.5 million of senior notes and a $4.6 million
                              short-term promissory note in connection with the
                              Telegroup acquisition, we would have had
                              outstanding approximately $651.8 million of
                              indebtedness on a consolidated basis. Because we
                              are a holding company that conducts our business
                              through our subsidiaries, all existing and future
                              indebtedness and other liabilities and
                              commitments of any of our subsidiaries, including
                              trade payables, will be structurally senior to
                              the new notes. As of March 31, 1999, our
                              consolidated subsidiaries had outstanding
                              aggregate liabilities of approximately $174.7
                              million, which included $28.6 million of
                              indebtedness.

Optional Redemption.........  We may redeem some or all of the new notes at the
                              redemption prices listed in "Description of
                              Exchange Notes--Optional Redemption" at any time
                              on or after January 15, 2004. Before January 15,
                              2002, we may redeem up to 35% of the original
                              principal amount of new notes at the redemption
                              price listed in "Description of Exchange Notes--
                              Optional Redemption" with the net cash proceeds
                              of one or more public equity offerings.

Change of Control...........  If we experience a change of control, each holder
                              of new notes may require us to purchase all or
                              any part of such holder's new

                                       6
<PAGE>

                             notes at a purchase price of 101% of the
                             principal amount thereof, plus accrued and unpaid
                             interest and liquidated damages, if any, to the
                             date of purchase.

Covenants..................  The indenture governing the new notes limits our
                             ability and that of our restricted subsidiaries
                             to:

                                  .incur additional indebtedness,

                                  .repurchase capital stock or subordinated
                               indebtedness,

                                  .make certain other restricted payments,

                                  .create certain liens,

                                  .enter into certain transactions with
                               affiliates,

                                  .sell assets,

                                  .issue or sell capital stock of our
                               restricted subsidiaries, or

                                  .enter into certain mergers and
                               consolidations.

Registration Rights........  If,

                                  .applicable law or SEC policy does not
                               permit us to effect the Exchange Offer,

                                  .the Exchange Offer is not consummated
                               within the prescribed periods, or

                                  .certain holders of the unregistered notes
                               notify us they are not permitted to participate
                               in, or would not receive freely tradable are
                               notes pursuant to, the Exchange Offer,

                             we will use our reasonable best efforts to cause
                             the SEC to declare effective a shelf registration
                             statement with respect to resale of the
                             unrequested notes and to keep the shelf
                             registration statement continuously effective
                             until up to two years after the date on which the
                             unrequested notes were sold. If we fail to
                             satisfy these registration obligations, we will
                             be required to pay liquidated damages to the
                             holders of the unregistered notes under certain
                             circumstances.

Use of Proceeds............  We will not receive any proceeds from the
                             exchange offer.

     expenses of such offerings payable by us, all as if they had occurred on
     January 1, 1998.

 (2) Gives pro forma effect to the Telegroup acquisition as if it had occurred
     on January 1, 1999. Also gives pro forma effect to:  (i) the sale of $200
     million of unregistered notes in January 1999 and the exchange offer
     contemplated hereby, and (ii) the issuance of an additional $45.5 million
     of senior notes in June 1999 pursuant to the January 1999 indenture in
     connection with the Telegroup acquisition, in each case less discounts,
     commissions and estimated expenses of such offerings payable by us, all as
     if they had occurred on January 1, 1999.

 (3) Net revenue is after provision for bad debt.

 (4) Pro forma interest expense for the year ended December 31, 1998 includes
     interest expense on the May 1998 senior notes, the $200 million of
     unregistered notes and the exchange offer contemplated hereby, the $45.5
     million of senior notes issued in connection with the Telegroup
     acquisition, and amortization of deferred financing costs. Pro forma
     interest expense for the three months ended March 31, 1999 includes
     amortization of deferred financing costs, and includes interest expense on
     all of the foregoing other than the May 1998 senior notes.

 (5) Consists primarily of net revenue from operations in the United States for
     all periods prior to 1997. Net revenue for periods ended subsequent to the
     year ended December 31, 1996 reflects our commencement of operations in
     Canada in April 1997.

 (6) Consists solely of net revenue from operations in Australia for the year

     year ended December 31, 1996 reflects our commencement of operations in
     Japan in October 1997.

 (7) Consists solely of net revenue from operations in the United Kingdom for
     all periods prior to 1998. Net revenue for periods ended subsequent to the
     year ended December 31, 1997 reflects our commencement of operations in
     Germany in August 1998.

 (8) As used herein, "EBITDA" is defined as income (loss) from operations plus
     depreciation and amortization expense. While EBITDA should not be
     construed as a substitute for operating income or a better measure of
     liquidity than cash flow from operating activities, which are determined
     in accordance with generally accepted accounting principles, it is
     included to provide additional information regarding our ability to meet
     our future debt service, capital expenditures and working capital
     requirements. EBITDA is not necessarily a measure of our ability to fund
     our cash needs and is not necessarily comparable to similarly titled
     measures of other companies.

 (9) Capital expenditures excludes assets acquired in business combinations and
     under terms of capital leases.

(10) Gives effect to the Telegroup acquisition, including the issuance of $45.5
     million of senior notes and a $4.6 million short-term promissory note in
     June 1999, and the payment of $43.9 million in cash, all in connection
     with the Telegroup acquisition, as if they had occurred on March 31, 1999.

(11) Consists of total current assets minus total current liabilities.

                                  RISK FACTORS

   You should carefully consider the following risks, in addition to the other
information contained elsewhere in this prospectus, in evaluating whether to
participate in the Exchange Offer.

We Have Substantial Indebtedness

   We have substantial indebtedness and the indenture governing the new notes
and the unregistered notes limits, but does not prohibit, our incurrence of
additional indebtedness. We expect that we will incur additional indebtedness
in the future and our level of indebtedness could have important consequences
to you, including the following:

  .  any additional indebtedness could make it more difficult for us to make
     payments of interest on our outstanding debt, including the new notes;

  .  we may limit our ability to obtain any necessary financing in the future
     for working capital, capital expenditures or other purposes;

  .  we must dedicate a substantial portion of our cash flow from operations,
     if any, to the payment of principal and interest on our indebtedness and
     this cash flow will not be available for our use elsewhere in our
     business;

  .  our flexibility in planning for, or reacting to, changes in our business
     could be limited;

  .  we may be at a competitive disadvantage because we are more highly
     leveraged than some of our competitors; and

  .  we may be more vulnerable in the event of a downturn in our business if
     we have a high level of indebtedness.

   We must substantially increase our net cash flow in order to meet our debt
service obligations and cannot assure you that we will be able to meet our debt
service obligations, including our obligations under the new notes. The holders
of such indebtedness can accelerate the maturity of such indebtedness if there
is a default and that could cause defaults under our other indebtedness. Such
defaults could result in a default on the new notes and could delay or preclude
payments of interest or principal thereon.

We Experienced Historical, and Will Experience Future Operating Losses,
Negative EBITDA and Net Losses

   We expect to continue to incur operating losses, and negative cash flow from
operations as we expand our operations and build-out and upgrade our
telecommunications network. Our net revenue growth in each of the last 16
quarters should not be considered to be indicative of future net revenue
growth. We cannot assure you that our net revenue will grow or be sustained in
future periods or that we will be able to achieve or sustain profitability or
generate positive cash flow from operations in any future period. If we cannot
achieve and sustain operating profitability or positive cash flow from
operations, we may not be able to meet our debt service or working capital
requirements, including our obligations with respect to the new notes.

We Must Obtain Additional Financing to Expand Our Service Offerings

   We continually evaluate the expansion of our service offerings and plan to
make further investments in and enhancements to our telecommunications network
and in distribution channels. To fund these additional cash requirements, we
anticipate that we will have to raise additional financing from public or
private equity or debt sources. Additionally, we may be required to seek
additional capital sooner than expected if:

  .  our plans or assumptions change or are inaccurate, including with
     respect to the development of our telecommunications network, the
     expansion of our service offerings, the scope of our operations and our
     operating cash flow;

                                       10
<PAGE>


  .  we consummate additional investments or acquisitions;

  .  we experience unexpected costs or competitive pressures; or

  .  our existing cash and any other borrowings prove to be insufficient.

We have agreed in the indenture and certain other agreements governing our
indebtedness to restrictive covenants that will affect, and in many respects
will limit or prohibit significantly, our ability to incur additional
indebtedness and to create liens. If we do raise additional funds through the
incurrence of debt, we would likely become subject to additional restrictive
financial covenants. If we are unable to obtain additional capital at all or on
acceptable terms, we may be required to reduce the scope of our expansion,
including the expansion of iPRIMUS.com, which could adversely affect our
business prospects and our ability to compete. We cannot assure you that we
will be able to raise equity capital, obtain capital lease or bank financing or
incur other borrowings on commercially reasonable terms, if at all, to fund any
such expansion or otherwise.

We Operate Using a Holding Company Structure and Will Rely on Our Subsidiaries
for Distributions to Service the New Notes

   We are a holding company and our principal assets are the stock of our
operating subsidiaries. Dividends, intercompany loans and other permitted
payments from our direct and indirect subsidiaries, and our own credit
arrangements, are our sources of funds to meet our cash needs, including the
payment of expenses and principal and interest on the new notes. Our
subsidiaries are legally distinct from us and have no obligation to pay amounts
due with respect to the new notes or to make funds available to us. Our
subsidiaries will not guarantee the new notes. Many of our subsidiaries are
organized in jurisdictions outside the United States. Their ability to pay
dividends, repay intercompany loans or make other distributions may be
restricted by, among other things, the availability of funds, the terms of
various credit arrangements entered into by them, as well as statutory and
other legal restrictions. Additionally, payments from our subsidiaries may
result in adverse tax consequences. If we do not receive dividends,
distributions and other payments from our subsidiaries, we would be restricted
in our ability to pay interest and principal on the new notes and on our
ability to utilize cash flow from one subsidiary to cover shortfalls in working
capital at another subsidiary.

   Additionally, creditors of the holding company, including the holders of the
new notes, and the holding company itself will generally have subordinate
claims against the assets of a particular subsidiary as compared to the
creditors of such subsidiary. Accordingly, the new notes will be structurally
subordinated to all existing and future indebtedness and other liabilities and
commitments of our subsidiaries, including trade payables. Our right to receive
assets of any subsidiary upon the liquidation or reorganization of such
subsidiary (and the consequent rights of the holders of the new notes to
participate in those assets) will be structurally subordinated to the claims of
such subsidiary's creditors. However, if the holding company itself is
recognized as a creditor, its claims would be subordinate to any secured
indebtedness of such subsidiary and any indebtedness of such subsidiary that is
senior to the holding company's claims. In addition, holders of our secured
indebtedness have a claim on the assets securing such indebtedness that is
prior to the claim of the holders of the new notes and would have a claim that
is pari passu with the claim of the holders of the new notes to the extent such
security did not satisfy such indebtedness. We have no significant assets other
than the stock of our subsidiaries. If we were to enter into a bank credit
facility or similar arrangement, we expect that the stock of the subsidiaries
would be pledged to secure any such credit facility or arrangement.

We Have Been Operating for Only a Limited Period of Time

   We have limited experience in operating our business. Our company was
founded in February 1994 and began generating operating revenues in March 1995.
We intend to enter additional markets or businesses, including offering
Internet services where we have limited or no operating experience.
Accordingly, we cannot assure you that our future operations will generate
operating or net income, and you must consider our prospects in light of the
risks, expenses, problems and delays inherent in establishing a new business in
a rapidly changing industry.

                                       11
<PAGE>


We Cannot Assure You That Our Internet Business Will Be Successful

   We have recently begun targeting businesses and residential customers for
Internet services through our newly formed subsidiary, iPRIMUS.com, and other
recently acquired ISPs. We intend to expand our offering of data and Internet
services worldwide. We have limited experience in the Internet business and
cannot assure you that we will successfully establish or expand the business.
Currently, we only provide Internet services to business and residential
customers in Australia, Canada and Germany, and offer Internet transmission
services in only the Indian Ocean/Southeast Asia regions through our satellite
earth station in London.

   The market for Internet connectivity and related services is extremely
competitive. Our primary competitors include other ISPs that have a significant
national or international presence and that focus on business customers. Many
of these carriers have substantially greater resources, capital and operational
experience than we do. We also expect we will experience increased competition
from traditional telecommunications carriers that expand into the market for
Internet services. In addition, we will require substantial additional capital
to make investments in our Internet operations and we may not be able to obtain
that capital on favorable terms.

   Further, even if we are able to establish and expand our Internet business,
we will face numerous risks that may adversely affect the operations of our
Internet business. These risks include:

  . competition in the market for Internet services;

  . our limited operating history as an ISP;

  . rapid changes in technology related to our Internet business;

  . uncertainty relating to the adoption of the Internet as a medium of
    commerce and communications;

  . vulnerability to unauthorized access, computer viruses and other
    disruptive problems due to the accidental or intentional actions of
    others;

  . adverse regulatory developments and the potential liability for
    information disseminated over our network; and

  . our need to manage the growth of our Internet business, including the
    need to enter into agreements with other providers of infrastructure
    capacity and equipment and to acquire other ISPs on acceptable terms.

We Are Developing Our Network and Moving Traffic onto Our Network

   Our long-term success is dependent upon our ability to design, implement,
operate, manage and maintain our telecommunications network, and our ability to
generate and move traffic onto the network. We have limited experience in these
activities. We have incurred additional fixed operating costs due to our
acquisition of telecommunications equipment and other assets of TresCom, London
Telecom, AT&T Canada, ACC Telenterprises and Telegroup. We will incur
additional fixed operating costs as we further expand the network. These costs
typically are in excess of the revenue attributable to the transmission
capacity funded by such costs until we generate additional traffic volume for
such capacity. We cannot guarantee that we will generate sufficient traffic to
economically utilize our capacity or that we can complete our network in a
timely manner or operate it efficiently. We also intend to expand our network
as more countries deregulate their telecommunications industries. We cannot
guarantee that we will be able to obtain the required licenses or purchase the
necessary equipment on favorable terms or, if we do, that we will be able to
successfully develop our network in those countries.

Managing Rapid Growth

   Our continued growth and expansion places a significant strain on our
management, operational and financial resources, and increases demands on our
systems and controls. We continue to add switches and fiber

                                       12
<PAGE>


optic cable and to expand our operations. We have expanded our retail
operations through our recent acquisitions of TresCom, London Telecom, the
consumer business of AT&T Canada, the residential long distance business of ACC
Telenterprises and the retail business of Telegroup. We have also recently
acquired several ISPs and created iPRIMUS.com, our subsidiary through which we
intend to operate our Internet businesses. To manage our growth effectively, we
must continue to implement and improve our operational and financial systems
and controls, purchase and utilize other transmission facilities, and expand,
train and manage our employee base. If we inaccurately forecast the movement of
traffic onto our network, we could have insufficient or excessive transmission
facilities and disproportionate fixed expenses. We cannot guarantee that we
will be able to further develop our facilities-based network or expand at the
rate presently planned, or that the existing regulatory barriers to such
expansion will be reduced or eliminated. As we proceed with our development, we
will place additional demands on our customer support, billing and management
information systems, on our support, sales and marketing and administrative
resources and on our network infrastructure. We cannot guarantee that our
operating and financial control systems and infrastructure will be adequate to
maintain and manage effectively our future growth.

Acquisition and Strategic Investment Risks

   A key element of our business strategy is to acquire or make strategic
investments in complementary assets and businesses, and a major portion of our
growth in recent years is as a result of such acquisitions. Acquisitions,
including our recent TresCom, London Telecom, AT&T Canada, ACC Telenterprises,
Telegroup, GlobalServe and TCP/IP acquisitions, and strategic investments
involve financial and operational risks. We may incur indebtedness in order to
effect an acquisition and will need to service that indebtedness. An
acquisition may not provide the benefits originally anticipated while we
continue to incur operating expenses. There may be difficulty in integrating
the service offerings, distribution channels and networks gained through
acquisitions and strategic investments with our own. In a strategic investment
where we acquire a minority interest in a company, we may lack control over the
operations and strategy of the business, and we cannot guarantee that such lack
of control will not interfere with the integration of services and distribution
channels of the business with our own. Although we attempt to minimize the risk
of unexpected liabilities and contingencies associated with acquired businesses
through planning, investigation and negotiation, such unexpected liabilities
may nevertheless accompany such strategic investments and acquisitions. We
cannot guarantee that we successfully will:

  .  identify attractive acquisition and strategic investment candidates;

  .  complete and finance additional acquisitions on favorable terms; or

  .  integrate the acquired businesses or assets into our own.

   We cannot guarantee that the integration of our business with any acquired
company's business, including the businesses of TresCom, London Telecom, AT&T
Canada, ACC Telenterprises, Telegroup, GlobalServe and TCP/IP will be
accomplished smoothly or successfully, if at all. If we encounter significant
difficulties in the integration of the existing services or technologies or the
development of new technologies, resources could be diverted from new service
development, and delays in new service introductions could occur. We cannot
guarantee that we will be able to take full advantage of the combined sales
forces' efforts. Successful integration of operations and technologies requires
the dedication of management and other personnel which may distract their
attention from our day-to-day business, the development or acquisition of new
technologies, and the pursuit of other business acquisition opportunities.

We Experience Intense Domestic and International Competition

   The long distance telecommunications industry is intensely competitive and
is significantly influenced by the marketing and pricing decisions of the
larger industry participants. The industry has relatively limited barriers to
entry in the more deregulated countries with numerous entities competing for
the same customers. Customers frequently change long distance providers in
response to the offering of lower rates or promotional incentives by
competitors. Generally, customers can switch carriers at any time. We believe
that competition in

                                       13
<PAGE>


all of our markets is likely to increase and that competition in non-United
States markets is likely to become more similar to competition in the United
States market over time as the non-United States markets continue to experience
deregulatory influences. Further deregulation in other countries such as
Canada, the United Kingdom, Germany and Japan, could result in greater
competition in telecommunications services offered in these countries. This
increase in competition could adversely affect net revenue per minute and gross
margin as a percentage of net revenue. We compete primarily on the basis of
price, particularly with respect to our sales to other carriers, and also on
the basis of customer service and our ability to provide a variety of
telecommunications products and services. Prices for long distance calls in
several of the markets in which we compete have declined in recent years and
are likely to continue to decrease. We cannot guarantee that we will be able to
compete successfully in the future.

   Many of our competitors are significantly larger than us, and many of our
competitors have:

    .  substantially greater financial, technical and marketing resources;

    .  larger networks;

    .  a broader portfolio of services;

    .  controlled transmission lines;

    .  stronger name recognition and customer loyalty; and

    .  long-standing relationships with our target customers.

In addition, many of our competitors enjoy economies of scale that can result
in a lower cost structure for transmission and related costs, which could cause
significant pricing pressures within the industry. Several long distance
carriers in the United States have introduced pricing strategies that provide
for fixed, low rates for calls within the United States. If this strategy is
widely adopted, it could have an adverse effect on our results of operations
and financial condition if increases in telecommunications usage do not result
or are insufficient to offset the effects of such price decreases.

   Recent and pending deregulation in various countries may encourage new
entrants to compete, including Internet service providers, cable television
companies and utilities. For example, the United States and 68 other countries
have committed to open their telecommunications markets to competition pursuant
an agreement under the World Trade Organization which began on January 1, 1998.
Further, in the United States once certain conditions are met under the United
States Telecommunications Act of 1996, the regional bell operating companies
will be allowed to enter the domestic long distance market, AT&T, MCI/WorldCom
and other long distance carriers will be allowed to enter the local telephone
services market, and any entity, including cable television companies and
utilities, will be allowed to enter both the local service and long distance
telecommunications markets. In addition, we could experience additional
competition in the Australian market from newly licensed telecommunications
carriers with the ongoing deregulation of the Australian telecommunications
market and the granting of additional carrier licenses.

We Depend on Transmission Facilities-Based Carriers

   We primarily connect our customers' telephone calls through transmission
lines that we lease under a variety of arrangements with other facilities-based
long distance carriers. Many of these carriers are, or may become, our
competitors. Our ability to maintain and expand our business is dependent upon
whether we continue to maintain favorable relationships with the facilities-
based carriers from which we lease transmission lines. If our relationship with
one or more of these carriers were to deteriorate or terminate, it could have a
material adverse effect upon our cost structure, service quality, network
diversity, results of operations and financial condition. Moreover, we lease
transmission lines from some vendors that currently are subject to tariff
controls and other price constraints which in the future may be changed.

                                       14

Risks Associated With International Operations

   A key element of our business strategy is to expand in international
markets. In many international markets, the existing incumbent carrier has
certain advantages, including:

    .  controlling access to the local networks;

    .  enjoying better brand recognition and brand and customer loyalty;
       and

    .  having significant operational economies, including a larger
       backbone network and foreign carrier agreements with other incumbent
       carriers and other service providers.

Moreover, the incumbent carrier may take many months to allow competitors to
interconnect to its switches. To achieve our objective of pursuing growth
opportunities in international markets, we may have to make significant
investments for an extended period before returns, if any, on such investments
are realized. In addition, we cannot guarantee that we will be able to obtain
the permits and operating licenses required by us to:

    .  operate our own transmission facilities or switches;

    .  obtain access to local transmission facilities; or

    .  market, sell and deliver competitive services in these markets.

In addition, such permits and operating licenses, if we obtain them, may not be
obtained in the time frame that we currently contemplate.

   There are additional risks inherent in doing business on an international
level which could materially adversely impact our international operations.
These risks include:

    .  unexpected changes in regulatory requirements, tariffs, customs,
       duties and other trade barriers;

    .  difficulties in staffing and managing foreign operations;

    .  problems in collecting accounts receivable;

    .  political risks;

    .  fluctuations in currency exchange rates;

    .  foreign exchange controls which restrict or prohibit repatriation of
       funds;

    .  technology export and import restrictions or prohibitions;

    .  delays from customs brokers or government agencies;

    .  seasonal reductions in business activity during the summer months
       and holiday periods; and

    .  potentially adverse tax consequences resulting from operating in
       multiple jurisdictions with different tax laws.

A significant portion of our net revenue and expenses is denominated, and is
expected to continue to be denominated, in currencies other than United States
dollars. Changes in exchange rates may have a significant effect on our results
of operations. We have not historically engaged in hedging transactions, and do
not currently contemplate engaging in hedging transactions to mitigate foreign
exchange risk.

   On January 1, 1999, 11 member countries of the European Union established
fixed conversion rates between their national currencies and the "euro". At
that time, the euro began trading on currency exchanges and became usable for
non- cash transactions. However, traditional currencies will continue to be
used until at least January 1, 2002. Given the extent of our current and
expected services in continental Europe and the nature of those services, we do
not currently expect euro conversion to have a material impact on operations or
cash flows. However, uncertainties exist as to the effects of euro conversion
on certain European customers and on the economies of the participating
countries. Euro conversion will also cause a better ability to compare

                                       15
<PAGE>

prices in different countries which may negatively impact pricing strategies in
different participating countries. We plan to continue to evaluate the impact
of euro conversion on our computer and financial systems, business processes,
market risk and price competition.

We Depend on Effective Information Systems

   To bill our customers, we must record and process massive amounts of data
quickly and accurately. We believe that our management information system will
have to grow as our business expands and it will have to change as new
technological developments occur. We believe that the successful implementation
and integration of new information systems and backroom support will be
important to our ability to

    .  develop and grow our business,

    .  monitor and control costs,

    .  bill our customers accurately and in a timely fashion, and

    .  achieve operating efficiencies.

We cannot guarantee that we will not encounter delays or cost-overruns or
suffer adverse consequences in implementing these systems. Any such delay or
other malfunction of our management information systems could have a material
adverse effect on our business, financial condition and results of operations.

We Must Modify our Systems to be Year 2000 Compliant

   In 1998, we began a comprehensive inventory and Year 2000 assessment of our
principal computer systems, network elements, software applications and other
business systems throughout the world. The Year 2000 problem is the result of
computer programs being written using two digits, rather than four digits, to
define the applicable year. Any of our systems, elements or applications that
have time-sensitive software may recognize a date using "00" as the year 1900
rather than the year 2000. This could result in improperly routed traffic, a
major system failure or miscalculations in invoices. We have completed our
inventory assessment and have begun repairing or replacing the most critical
items that we have determined not to be Year 2000 compliant. We expect to
complete the repair, replacement, testing and certification of substantially
all non-compliant network elements by September 30, 1999. We are using both
internal and external resources to identify, correct or reprogram, and test our
systems for Year 2000 compliance. In addition, we are contacting third party
suppliers of major equipment, software, systems and services that we use to
identify and, to the extent possible, to resolve issues involving Year 2000
compliance. However, we have limited or no control over the actions of these
third party suppliers. Consequently, we cannot guarantee that these suppliers
will resolve any or all Year 2000 issues before the occurrence of a material
disruption to our business or any of our customers.

   We expect to incur in the aggregate approximately $3 to $5 million in
expenditures during 1999 to complete our Year 2000 compliance program. These
estimates do not include the cost of systems, software and equipment that are
being replaced or upgraded in the normal course of business. The costs of
modifying our network elements, software and systems for Year 2000 compliance
are being funded from existing cash resources. If we do not achieve compliance
prior to December 31, 1999, or if we fail to identify and remedy all critical
Year 2000 problems, our results of operations or financial condition could be
materially affected. We have begun to develop appropriate contingency plans to
mitigate, to the extent possible, any significant Year 2000 noncompliance and
expect to complete our contingency plans by September 30, 1999. If we are
required to implement our contingency plans, the cost of Year 2000 compliance
may be greater than the amount referenced above and cannot guarantee that these
plans will be adequate.

We Experience Risks of Industry Changes That Affect Our Competitiveness and Our
Financial Results

   The international telecommunications industry is changing rapidly due to:

    .  deregulation;

    .  privatization of incumbent carriers;

                                       16
<PAGE>


    .  technological improvements;

    .  expansion of telecommunications infrastructure; and

    .  the globalization of the world's economies.

In addition, deregulation in any particular market may cause such market to
shift unpredictably. We cannot guarantee that we will be able to compete
effectively or adjust our contemplated plan of development to meet changing
market conditions.

   The telecommunications industry generally is experiencing a rapid
technological evolution. New products and service offerings are being
introduced. Satellite and undersea cable transmission capacity is increasingly
available for services similar to those we provide. Potential developments that
could adversely affect us if we do not anticipate them or appropriately respond
to them include:

    .  improvements in transmission equipment;

    .  development of switching technology allowing voice/data/video
       multimedia transmission simultaneously; and

    .  commercial availability of competitively-priced Internet-based
       domestic and international switched voice/data/video services.

Our profitability will depend on our ability to anticipate, assess and adapt to
rapid technological changes and our ability to offer, on a timely and cost-
effective basis, services that meet evolving industry standards. We cannot
guarantee that we will be able to assess or adapt to such technological changes
at a competitive price, maintain competitive services or obtain new
technologies on a timely basis or on satisfactory terms.

We May Be Affected by Natural Disasters

   Many of the geographic areas where we conduct our business may be affected
by natural disasters, including hurricanes and tropical storms. Hurricanes,
tropical storms and other natural disasters could have a material adverse
effect on our business by damaging our network facilities or curtailing
telephone traffic as a result of the effects of such events, such as
destruction of homes and businesses.

We Depend on Key Personnel

   We depend upon the efforts of our management team and our key technical,
marketing and sales personnel, particularly those of K. Paul Singh, our
Chairman and Chief Executive Officer. If we lose the services of one or more of
these key individuals, particularly Mr. Singh, our business and its future
prospects could be materially and adversely affected. We have entered into an
employment agreement with Mr. Singh, which continues until May 30, 2000, and
from year to year thereafter unless terminated. We do not maintain any key
person life insurance on the lives of any officer, director or key employee.
Our future success will also depend on our ability to attract and retain
additional key management and technical and sales personnel required in
connection with the growth and development of our business. The competition to
hire qualified employees and personnel in the telecommunications and Internet
industries is intense, particularly in non-U.S. markets, and there are a
limited number of persons with knowledge of and experience in particular
sectors of the telecommunications industry. We cannot guarantee that we will be
successful in attracting and retaining such executives and personnel.

We are Subject to Potential Adverse Effects of Regulation

   As a multinational telecommunications company, we are subject to varying
degrees of regulation in each of the jurisdictions in which we provide, or
expect to provide, our services. Local laws and regulations, and the
interpretation of such laws and regulations, differ significantly among the
jurisdictions in which we operate. There can be no assurance that future
regulatory, judicial and legislative changes will not have a material

                                       17
<PAGE>


adverse effect on us, that domestic or international regulators or third
parties will not raise material issues with regard to our compliance or
noncompliance with applicable regulations.

   United States. In the United States, our services are subject to the
provisions of the United States Communications Act of 1934, as amended by the
United States 1996 Telecommunications Act, and the Federal Communications
Commission regulations thereunder, as well as the applicable laws and
regulations of the various states administered by the relevant state public
service commissions. The recent trend in the United States has been in the
direction of reduced regulation which has also given AT&T, the largest
international and domestic long distance carrier in the United States,
increased pricing and market entry flexibility that has permitted it to compete
more effectively with smaller carriers, such as us. In addition, the 1996
Telecommunications Act has opened the United States market to increased
competition.

   The FCC and relevant state public service commissions exercise authority to
regulate ownership of transmission facilities, provision of services and the
terms and conditions under which our services are provided. In addition, we
file tariffs listing the rates, terms and conditions of the services we
provide. Any failure to maintain proper federal and state tariffs or
certification, or any finding by the federal or state agencies that we are not
operating under permissible terms and conditions, may result in an enforcement
action or investigation.

   To originate and terminate calls, long distance carriers such as us must
purchase "access" from the local exchange carriers. Access charges represent a
significant portion of our cost of revenue and, generally, such access charges
are regulated by the FCC. Under new FCC rules, local exchange carriers will be
permitted to allow certain volume discounts in the pricing of access charges.
It is possible that many long distance carriers, including us, could be placed
at a significant cost disadvantage to larger competitors. We also contribute to
universal service funds based on revenues collected in the United States. In a
pending rulemaking, the FCC may amend its rules to require us to contribute
based on foreign revenues as well as domestic revenues.

   The FCC and certain state agencies also impose prior approval requirements
on transfers of control, including pro forma transfers of control resulting
from corporate reorganizations, and assignments of regulatory authorizations.
Applicable prior approval requirements may delay, prevent or deter a change in
our control. The FCC has established and administered a variety of
international service regulations, including the International Settlements
Policy which governs the settlement between U.S. carriers and their foreign
correspondents of the cost of terminating traffic over each other's networks,
the "benchmark" settlement rates for such settlement and permissible exceptions
to these policies. The FCC recently approved rules that, when effective, will
remove the International Settlements Policy with respect to arrangements with
foreign carriers. To the extent that the International Settlements Policy still
applies, the FCC could find that, absent a waiver, certain terms of our foreign
carrier agreements do not meet the requirements of the International
Settlements Policy. The FCC could, among other things, issue a cease and desist
order or impose fines if it finds that these agreements conflict with the
International Settlements Policy. We do not believe that any such fine or order
would have a material adverse effect on us. The FCC also regulates the nature
and extent of foreign ownership in radio licenses and our foreign carrier
affiliations.

   Regulatory requirements pertinent to our operations have recently changed
and will continue to change as a result of the World Trade Organization
Agreement, federal legislation, court decisions, and new and revised policies
of the FCC and state public service commissions. In particular, the FCC
continues to refine its international service rules to promote competition,
reflect and encourage liberalization in foreign countries, and reduce
international accounting rates toward cost. Among other things, such changes
may increase competition and alter our ability to compete with other service
providers, to continue providing the same services, or to introduce services
currently planned for the future. The impact of any changes in applicable
regulatory requirements on our operations cannot be predicted.

   Canada. In Canada, the operations of telecommunications carriers are
regulated by the Canadian regulatory agency known as the Canadian Radio-
television and Telecommunications Commission. The CRTC has recently established
a new competitive regulatory framework governing the international segment of
the

                                       18
<PAGE>


long-distance market, eliminating certain barriers to competition. In addition,
foreign ownership rules for facilities-based carriers have now been waived in
relation to ownership of international submarine cables landed in Canada and
satellite earth stations used for telecommunication purposes. Effective January
1, 1999 all international service providers must be licensed by the CRTC under
the Canadian Telecommunications Act of 1993. Our operations will remain subject
to conditions of our CRTC license, which address matters such as competitive
conduct and consumer safeguards, and to a regime of contribution charges
(roughly the equivalent of access charges in the United States). There can be
no assurance that the new regulatory framework, once implemented in Canada,
will allow us to compete effectively in offering telecommunications services.
In addition, there can be no assurance that any future changes in or additions
to law, regulations, government policy or administrative rulings will not have
a material adverse impact on our competitive position, growth and financial
performance.

   Australia. In Australia, the provision of our services is subject to federal
regulation pursuant to the Australian Telecommunications Act 1997 and the
Australian Trade Practices Act 1974. We are licensed under the Australian
Telecommunications Act of 1997 to own and operate transmission facilities in
Australia. Under the regulatory framework, we must comply with legislated
"service provider" rules contained in the Telecom Act covering matters such as
compliance with the Telecom Act, operator services, regulation of access,
directory assistance, provision of information to allow maintenance of an
integrated public number database, and itemized billing.

   The Australian Communications Authority regulates the licensing of carriers
and certain technical matters, and the Australian Competition and Consumer
Commission has the role of promotion of competition and consumer protection. As
a licensed carrier, we are required to comply with our own license and are
under the regulatory control of the Australian Communications Authority and the
Australian Competition and Consumer Commission. Anti-competitive practices will
also continue to be regulated by the Trade Practices Act. In addition, other
federal legislation, various regulations pursuant to delegated authority and
legislation, ministerial declarations, codes, directions, licenses, statements
of Commonwealth Government policy and court decisions affecting
telecommunications carriers also apply to us. There can be no assurance that
future declarations, codes, directions, licenses, regulations, and judicial and
legislative changes will not have a material adverse effect on us.

   Carriers must also meet the universal service obligation to assist in
providing all Australians, particularly those living in remote areas, with
reasonable access to standard telephone services. Telstra, as the only
universal service provider, has submitted a claim to the Australian
Communications Authority that, if adopted, could result in material charges to
carriers such as us. The Australian government has not accepted Telstra's model
and has referred the model and the criteria for determining the size of this
obligation to the Australian Communications Authority for review. The outcome
from the Australian Communications Authority's assessment and the Australian
government's policy considerations is expected to result in a levy that will
not be material for us. However, there can be no assurance that the Australian
Communications Authority will not make an assessment of a universal service
charge that would be material.

   United Kingdom. In the United Kingdom, the provision of our services is
subject to and affected by regulations introduced by the United Kingdom
telecommunications regulatory authority, the Office of Telecommunications under
the United Kingdom Telecommunications Act of 1984. Since the break up of the
United Kingdom telecommunications duopoly consisting of British Telecom and
Mercury in 1991, it has been the stated goal of Oftel to create a competitive
marketplace from which detailed regulation could eventually be withdrawn. The
regulatory regime currently being introduced by Oftel has a direct and material
effect on our ability to conduct our business. Oftel has imposed mandatory rate
reductions on British Telecom in the past, which reductions are expected to
continue for the foreseeable future, and this has had, and may continue to
have, the effect of reducing the prices we can charge our customers. There can
be no assurance that future changes in regulation and government will not have
a material adverse effect on our business, results of operations and financial
condition.

                                       19
<PAGE>

   Japan. Our services in Japan are subject to regulation by the Ministry of
Post and Telecommunications under the Japanese Telecommunications Business Law.
We have obtained licenses as a Type I business, which allows us to provide
telecommunications services using our own facilities, and as a Special Type II
business, which allows us to provide telecommunications services over
international circuits leased from another carrier, or domestic service in
Japan over leased circuits if the volume of traffic exceeds a certain amount.
We may also provide over leased lines basic telecommunications services, value-
added services and services to closed user groups. There can be no guarantee
that the Japanese regulatory environment will allow us to provide services in
Japan at competitive rates.

   Germany. Our services in Germany are governed by the German
Telecommunications Act of 1996, which, with respect to most of its provisions,
became effective at the end of July 1996, while all of its market liberalizing
provisions took effect on January 1, 1998. A change in regulatory policy has
taken place which will require us to invest in additional points of presence
and transmission lines in order to continue to receive the lowest available
interconnection rates. However, the build-out of our German network is
currently hindered by Deutsche Telekom's insufficient capacities and consequent
order backlog of points of presence. Further changes in regulatory policy or
court decisions could result in our having to pay less favorable
interconnection prices and/or having to invest into a Germany-wide license to
be able to continue our current services. The Regulierungsbehorde fur
Telekommunikation und Post (RegTP) has in particular invited Deutsche Telekom
to launch a regulatory authorization of additional interconnection fees to be
paid by small network operators for so called "atypical traffic", a designation
applicable to most of our traffic. Moreover, we are subject to certain
regulatory requirements when we operate under our license, including the
requirement that we present our standard terms and conditions to German
regulators and possibly that we contribute to universal service mechanisms.

   Deutsche Telekom has exercised its option to terminate its current
interconnection agreement with us as of the end of 1999 and has asked that
renegotiations be commenced. Deutsche Telekom has at the same time presented us
with a new draft interconnection agreement containing terms less favorable than
in the current agreement. Such less favorable terms include, among other
things, higher interconnection fees; higher resale fees for certain
interconnecting calls; minimum traffic volume requirements; and the requirement
to extend our license to a Germany-wide license. Most of these new terms have
not been accepted by the RegTP for the period of the current interconnection
regime until the end of 1999. The same terms may, however, be introduced as of
the year 2000 and may adversely affect our business.

   There can be no assurance that the regulatory environment in Germany
generally or the applicable interconnection rates with Deutsche Telekom will
allow us to provide telecommunications services competitively with other
providers.

   Latin America. We may decide to install switches and other network equipment
in several Latin American countries. Some of these countries allow only limited
competition to the incumbent telephone carrier, and others require prior
authorization before providing competitive services. Others, such as El
Salvador and Guatemala, do not require prior authorization but would require us
to obtain numbers or interconnection with the incumbent carrier. We are
currently providing to customers in certain Latin American countries
international call reorigination or similar types of services that do not
require us to have a presence in the foreign country. Some of these countries
may prohibit some or all forms of call reorigination. There can be no guarantee
that we will be able to obtain any authorizations or otherwise take the actions
necessary to provide services in these countries.

   Other Jurisdictions. We intend to expand our operations into other
jurisdictions as such markets deregulate and we are able to offer a full range
of switched public telephone services to our customers. In addition, in
countries that enact legislation intended to deregulate the telecommunications
sector or that have made commitments to open their markets to competition in
the World Trade Organization Agreement, there may be significant delays in the
adoption of implementing regulations and uncertainties as to the implementation
of the deregulatory programs which could delay or make more expensive our entry
into such

                                       20
<PAGE>

additional markets. Our ability to enter a particular market and provide
telecommunications services is dependent upon the extent to which the
regulations in a particular market permit new entrants. In some countries,
regulators may make subjective judgments in awarding licenses and permits,
without any legal recourse for unsuccessful applicants. In the event we are
able to gain entry into such a market, no assurances can be given that we will
be able to provide a full range of services in such market. In addition, we may
have to modify significantly our operations to comply with changes in the
regulatory environment in such market and any such changes may have a material
adverse effect on our business, results of operations or financial condition.

A Group of Our Stockholders Could Exercise Significant Influence Over Our
Affairs

   As of July 15, 1999, our executive officers and directors beneficially owned
9,942,992 shares of our common stock, representing 33.2% of the outstanding
common stock. The executive officers and directors have also been granted
options to purchase an additional 593,336 shares of our common stock which vest
after July 15, 1999. Of these amounts, Mr. K. Paul Singh, our Chairman and
Chief Executive Officer, beneficially owns 4,761,839 shares of our common
stock, including options to purchase 371,433 shares of our common stock.
Investors affiliated with E.M. Warburg, Pincus & Co., LLC beneficially own
3,875,689 shares of our common stock. As a result, the executive officers,
directors and Warburg, Pincus exercise significant influence over such matters
as the election of our directors, amendments to our charter, other fundamental
corporate transactions such as mergers and asset sales, and otherwise the
direction of our business and affairs. Additionally, under the terms of a
shareholders' agreement among Warburg, Pincus, Mr. Singh and us, entered into
in connection with our merger with TresCom, we agreed to nominate one
individual selected by Warburg, Pincus and reasonably acceptable to our non-
employee directors, to serve as a member of our board of directors. This
nomination right remains effective so long as Warburg, Pincus is the beneficial
owner of 10% or more of our outstanding common stock. In June 1998, Douglas
Karp joined our board of directors pursuant to the foregoing arrangement.

There Could Be No Market for the New Notes

   The new notes are a new issue of securities, have no established trading
market, and may not be widely distributed. We do not intend to list the new
notes on any national securities exchange or to seek to have them admitted to
trade on The Nasdaq Stock Market. We cannot guarantee that an active public or
other market will develop for the new notes. If a trading market does not
develop or is not maintained, holders of the new notes may experience
difficulty in reselling the new notes or may be unable to sell them at all. If
a market for the new notes develops, it may be discontinued at any time. If a
public trading market develops for the new notes, future trading prices of the
new notes will depend on many factors, including prevailing interest rates, our
results of operations and the market for similar securities. The price at which
the holders of new notes will be able to sell such new notes is not assured and
the new notes could trade at a premium or discount to their purchase price or
face value. Depending on prevailing interest rates, the market for similar
securities and other facts, including our financial condition, the new notes
may trade at a discount from their principal amount.

   The liquidity of, and trading market for, the new notes also may be
adversely affected by declines in the market for the 1997 Senior Notes,
declines in the market for the 1998 Senior Notes and in general declines in the
market for similar securities issued by other companies. Any such decline may
adversely affect such liquidity and trading markets independent of our
financial performance and prospects.

The Notes Have Not Been Registered under State Securities Laws

   The notes have not been registered or qualified under any state securities
laws. The Exchange Offer is being made both to U.S. institutional investors,
pursuant to exemptions from such laws for sales to such investors, and to non-
U.S. persons, as state securities laws do not apply to sales to persons who are
not residents of any state. In order to acquire the unregistered notes, each
holder was required to represent to us that it was either (i) a "qualified
institutional buyer", (ii) an institutional "accredited investor" or (iii) a
non-

                                       21
<PAGE>

U.S. person. Holders who wish to exchange their unregistered notes for notes
pursuant to the Exchange Offer will be required to represent to us that they
remain institutional investors or non-U.S. persons. Any holder who no longer
qualifies as an institutional investor or who is no longer a non-U.S. person,
will not be entitled to exchange its unregistered notes for notes in the
Exchange Offer, unless another state securities law exemption is available. If
no such exemption is available, the holder will continue to hold the
unregistered notes, which will continue to be subject to the restrictions on
transfer as set forth in the legend thereon.

Consequences of Failure to Exchange

   Holders of unregistered notes who do not exchange their unregistered notes
for new notes pursuant to the Exchange Offer will continue to be subject to the
restrictions on transfer of such unregistered notes as set forth in the legend
thereon since the unregistered notes were issued pursuant to exemptions from,
or in transactions not subject to, the registration requirements of the
Securities Act and applicable state securities laws. In general, the
unregistered notes may not be offered or sold, unless registered under the
Securities Act, except pursuant to an exemption from, or in a transaction not
subject to, the Securities Act and applicable state securities laws. We do not
currently anticipate that we will register the unregistered notes for resale
under the Securities Act. New notes issued pursuant to the Exchange Offer in
exchange for unregistered notes may be offered for resale, resold or otherwise
transferred by the holders without compliance with the registration and
prospectus delivery provisions of the Securities Act provided that such new
notes are acquired in the ordinary course of such holders' business and such
holders have no arrangement with any person to participate in the distribution
of such new notes. However, the foregoing is not applicable to any such holder
which is our "affiliate" and other than any broker-dealer who purchased
unregistered notes directly from us for resale pursuant to Rule 144A under the
Securities Act or any other available exemption under the Securities Act. Each
broker-dealer that acquired unregistered notes for its own account as a result
of market making or other trading activities and that receives new notes for
its own account pursuant to the Exchange Offer must acknowledge that it will
deliver a prospectus in connection with any resale of such new notes. This
prospectus may be used by a broker-dealer in connection with resales of new
notes received in exchange for unregistered notes where such unregistered notes
were acquired by such broker-dealer as a result of market-making activities or
other trading activities. We have agreed that, for a period of 180 days after
the effective date of this prospectus, we will make this prospectus available
to any broker-dealer for use in connection with any such resale. However, to
comply with the securities laws of certain jurisdictions, if applicable, the
new notes may not be offered or sold unless they have been registered or
qualified for sale in such jurisdictions or an exemption from registration or
qualification is available and is complied with. To the extent that
unregistered notes are tendered and accepted in the Exchange Offer, the trading
market for untendered and tendered but unaccepted unregistered notes will be
adversely affected.

                            RECENT DEVELOPMENTS

 Acquisition of Telegroup Retail Assets

   Effective June 1, 1999, we acquired the global retail business of Telegroup,
including the acquisition of selected foreign subsidiaries, which includes:

  . Telegroup's global retail business of approximately 372,000 customers;

  . Two carrier grade switches, one located in the New York City area and one
    located in London;

  . 14 switching platforms and POPs located in the United Kingdom, Germany,
    France, the Netherlands, Denmark, Switzerland, Italy, Japan and Hong
  Kong;

  . Telegroup's global network of sales agents;

  . A Web-based order-entry and provisioning system for agents; and

  . A global network operations center and call center.

   We paid the $71.8 million purchase price, plus $22.2 million for certain
current assets,by issuing $45.5 million in aggregate principal amount of our 11
1/4% senior notes due 2009 and by issuing a $4.6 million short-term promissory
note, and paying the remainder in cash. The purchase price is subject to
adjustment. The acquisition had an effective date of June 1, 1999 such that the
financial results of the acquired business will be included in the Company's
results beginning June 1, 1999.

   We expect that this acquisition will result in approximately $150 million of
sustainable retail revenues annually after taking into account attrition in
Telegroup's customer base, which began to occur prior to the Telegroup
acquisition and which we expect to continue for the near future.

 Acquisition of AT&T Canada Consumer Business

   In May 1999, we purchased the residential long distance customer base and
customer support assets and residential Internet customers and network of AT&T
Canada and ACC Telenterprises for a purchase price of C$58.1 million
(approximately $39.4 million as of May 31, 1999). We also entered into a
strategic alliance pursuant to which AT&T Canada agreed to:

  .  provide us with underlying network services in Canada for five years;

  .  provide Canadian domestic termination for our global customers;

  .  provide customer support services to the customer base transferred to us
     for up to twelve months after the purchase; and

  .  license to us its bill face for six months after the purchase.

We intend to integrate the assets and residential long distance customer base
of AT&T Canada and ACC Telenterprises into Primus Canada, our wholly-owned
operating subsidiary in Canada. With this transaction, we acquired
approximately 428,000 retail customers, including 28,000 residential Internet
customers and related POPs, and we believe we are now the second largest
alternative carrier in Canada based on revenue.

 Internet and Data Services

   In May 1999, we organized our Internet and data services business into a new
subsidiary, iPRIMUS.com, which will provide services in some of the markets
where we operate. We expect that iPRIMUS.com will use our existing global
network infrastructure to offer a full range of Internet Protocol-based data
and voice communications services. In February 1999, we acquired Globalserve
Communications, a leading ISP in Canada, and we acquired the remaining 40%
interest in Hotkey Internet Services that we did not previously own. In
May 1999, we also acquired TCP/IP GmbH, an independent German ISP. TCP/IP
operates the Contrib.Net Internet backbone. As a result of these acquisitions,
we are now providing Internet services to business and residential customers in
Australia, Canada and Germany. With our satellite earth station in London, we
offer Internet transmission services in the Indian Ocean/Southeast Asia region.

 Global Crossing Reciprocal Capacity Purchase Agreement

   In May 1999, we entered into a reciprocal capacity purchase agreement with
Global Crossing Holdings Ltd. Under the agreement, we agreed to purchase up to
$50 million of fiber capacity from Global Crossing and Global Crossing agreed
to purchase up to $25 million of capacity on our global satellite network.

 Acquisition of London Telecom

   In March 1999, we acquired London Telecom, a provider of domestic and
international long distance services to approximately 162,000 residential and
business customers in Canada and substantially all of the operating assets of
Wintel CNC Communications, Inc. and Wintel CNT Communications, Inc., which are
Canadian-based long distance telecommunications providers affiliated with the
London Telecom companies, for C$76 million (approximately $50.4 million as of
March 31, 1999) in cash. As part of this acquisition, we acquired network
assets as well as call centers located in Toronto and Vancouver. We intend to
continue marketing the London Telecom services under the London Telecom brand
names.

                               THE EXCHANGE OFFER

Purpose and Effect

   We sold the initial unregistered notes to the initial purchasers, including
Lehman Brothers, Inc., Merrill Lynch, Pierce, Fenner & Smith Incorporated and
Morgan Stanley & Co. Incorporated, on January 29, 1999, pursuant to a purchase
agreement entered into as of January 22, 1999 by and between us and the initial
purchasers. The initial purchasers subsequently resold the initial notes in
reliance on Rule 144A under the Securities Act and certain other exemptions
under the Securities Act. We and the initial purchasers also entered into a
registration rights agreement, pursuant to which we agreed, with respect to the
initial notes, to

    (i) cause to be filed with the Commission as promptly as practicable a
        registration statement under the Securities Act concerning the
        exchange offer,

    (ii) use our reasonable best efforts to cause such registration
         statement to be declared effective by the Commission on or prior
         to June 28, 1998 and

    (iii) file all pre- and post-effective amendments necessary to cause
          such registration statement to become effective and cause all
          necessary filings in connection with the registration and
          qualification of the new notes under the "blue sky" laws of such
          jurisdictions as are necessary to consummate the exchange,

    (iv) use our reasonable best efforts to cause the exchange offer to be
         consummated on or before July 28, 1998, and

    (v) deliver the new notes in the same aggregate principal amount as the
        aggregate principal amount of the initial unregistered notes as are
        tendered by holders thereof pursuant to the exchange offer.

We also agreed to use our reasonable best efforts to keep the registration
statement effective for no less than 20 days. This exchange offer is intended
to satisfy our exchange offer obligations under the registration rights
agreement.

Terms of the Exchange Offer

   We hereby offer, upon the terms and subject to the conditions set forth
herein and in the accompanying Letter of Transmittal, to exchange $1,000 in
principal amount of the new notes for each $1,000 in principal amount of the
outstanding unregistered initial notes. We will accept for exchange any and all
initial notes that are validly tendered on or prior to 5:00 p.m., New York City
time, on August 12, 1999. Tenders of the initial notes may be withdrawn at any
time prior to 5:00 p.m., New York City time, on August 12, 1999. This exchange
offer is not conditioned upon any minimum principal amount of the initial notes
being tendered for exchange. However, the exchange offer is subject to the
conditions, terms and provisions of the registration rights agreement. The form
and terms of the new notes will be identical in all material respects to the
form and terms of the initial notes, except that

    (i) the new notes have been registered under the Securities Act and,
        therefore, will not bear legends restricting the transfer thereof,

    (ii) subject to certain limited exceptions, holders of new notes will
         not be entitled to liquidated damages, and

    (iii) holders of new notes will not be, and upon consummation of the
          exchange offer, holders of initial notes will no longer be,
          entitled to certain rights under the registration rights
          agreement intended for holders of unregistered securities.

   Initial notes may be tendered only in multiples of $1,000. Subject to the
foregoing, holders may tender less than the aggregate principal amount
represented by the initial notes held by them, provided that they

                                       26
<PAGE>

appropriately indicate this fact on the Letter of Transmittal accompanying the
tendered initial notes (or so indicate pursuant to the procedures for book-
entry transfer).

   As of the date of this Prospectus, $200.0 million in aggregate principal
amount of the initial notes is outstanding. As of July 29, 1999, CEDE was the
sole registered holder of the initial notes and held $200.0 million of
aggregate principal amount of the initial notes for 22 of its participants.
Solely for reasons of administration (and for no other purpose), we have fixed
the close of business on July 30, 1999, as the record date for purposes of
determining the persons to whom this Prospectus and the Letter of Transmittal
will be mailed initially. Only a holder of the initial notes (or such holder's
legal representative or attorney-in-fact) may participate in the exchange
offer. There will be no fixed record date for determining holders of the
initial notes entitled to participate in the exchange offer. We believe that,
as of the date of this Prospectus, no such the holder is our affiliate (as
defined in Rule 405 under the Securities Act).

   We shall be deemed to have accepted validly tendered initial notes when, as
and if we have given oral or written notice thereof to the exchange agent. The
exchange agent will act as agent for the tendering holders of initial notes and
for the purposes of receiving the new notes from us.

   If any tendered initial notes are not accepted for exchange because of an
invalid tender, the occurrence of certain other events set forth herein or
otherwise, certificates for any such unaccepted initial notes will be returned,
without expense, to the tendering holder thereof as promptly as practicable
after the expiration date.

Expiration Date; Extensions; Amendments

   The expiration date of the exchange offer is August 12, 1999 at 5:00 p.m.,
New York City time, unless we, in our sole discretion, extend the exchange
offer, in which case the expiration date shall be the latest date and time to
which the exchange offer is extended.

   In order to extend the exchange offer, we will notify the exchange agent of
any extension by oral or written notice and will make a public announcement
thereof, each prior to 9:00 a.m., New York City time, on the next business day
after the previously scheduled expiration date. Such notice and public
announcement shall set forth the new expiration date of the exchange offer.

   We reserve the right, in our sole discretion,

    (i) to delay accepting any initial notes,

    (ii) to extend the exchange offer,

    (iii) if any of the conditions set forth below under "Conditions of the
          Exchange Offer" shall not have been satisfied, to terminate the
          exchange offer by giving oral or written notice of such delay,
          extension or termination to the exchange agent, and

    (iv) to amend the terms of the exchange offer in any manner.

   If the exchange offer is amended in a manner determined by us to constitute
a material change, we will, in accordance with applicable law, file a post-
effective amendment to the registration statement and resolicit the registered
holders of the initial notes. If we file a post-effective amendment, we will
notify the exchange agent of an extension of the exchange offer by oral or
written notice, and will make a public announcement thereof, each prior to 9:00
a.m., New York City time, on the next business day after the effectiveness of
such post-effective amendment. Such notice and public announcement shall set
forth the new expiration date, which new expiration date shall be no less than
five days after the then applicable expiration date.

Conditions of the Exchange Offer

   The exchange offer is not conditioned upon any minimum principal amount of
initial notes being tendered for exchange. However, the exchange offer is
subject to the condition that it does not violate any applicable law or
interpretation of the staff of the Commission.

                                       27
<PAGE>

   Further, as a condition to its participation in the exchange offer, each
holder of initial notes (including, without limitation, any holder who is a
broker-dealer) will be required to furnish a written representation to us
(which may be contained in the Letter of Transmittal to the effect that such
holder

    (i)  is not our affiliate,

    (ii) is not engaged in, or does not intend to engage in, and has no
         arrangement or understanding with any person to participate in, a
         distribution of the new notes to be issued in the exchange offer
         and

    (iii) is acquiring the new notes in its ordinary course of business.

Each holder using the exchange offer to participate in a distribution of the
new notes will be required to acknowledge and agree that, if the resales are of
new notes obtained by such holder in exchange for initial notes acquired
directly from us or our affiliate, it (1) could not, under Commission policy as
in effect on the date of the registration rights agreement, rely on the
position of the Commission enunciated in Morgan Stanley and Co., Incorporated
(available June 5, 1991) and Exxon Capital Holdings Corporation (available May
13, 1988), as interpreted in the Commission's letter to Shearman & Sterling
(available July 2, 1993) and K-III Communications Corporation (available May
14, 1993), or similar no-action or interpretive letters, and (2) must comply
with the registration and prospectus delivery requirements of the Exchange Act
in connection with a secondary resale transaction and that such a secondary
sale transaction must be covered by an effective registration statement
containing the selling security holder information required by Item 507 or 508,
as applicable, of Regulation S-K, unless an exemption from registration is
otherwise available.

   In addition, each holder of initial notes will be required to furnish a
written representation to the Company (which may be contained in the Letter of
Transmittal to the effect that such holder is either (A) a "qualified
institutional buyer" within the meaning of Rule 144A under the Securities Act,
(B) an institutional "accredited investor" within the meaning of subparagraph
(a)(1), (2), (3) or (7) of Rule 501 under the Securities Act or (C) a non-U.S.
person within the meaning of Regulation S under the Securities Act.

Termination of Certain Rights

   The registration rights agreement provides that, subject to certain
exceptions, in the event of a registration default, holders of initial notes
are entitled to receive liquidated damages, if

    (i) we fail to file with the Commission any of the registration
        statements required by the registration rights agreement on or
        before the date specified therein for such filing,

    (ii) any of such registration statements are not declared effective by
         the Commission on or prior to the date specified for such
         effectiveness in the registration rights agreement,

    (iii) the exchange offer has not been consummated within 30 days after
          the effectiveness target date with respect to the exchange offer
          registration statement or

    (iv) any registration statement required by the registration rights
         agreement is filed and declared effective but thereafter ceases to
         be effective or fails to be usable for its intended purpose
         without being succeeded within five business days by a post-
         effective amendment to such registration statement that cures such
         failure and that is itself immediately declared effective (each
         event referred to in clauses (i) through (iv) above being a
         registration default), additional cash interest shall accrue to
         each holder of the notes commencing upon the occurrence of such
         registration default in an amount equal to .50% per annum of the
         principal amount of notes held by such holder.

The amount of liquidated damages will increase by an additional .50% per annum
of the principal amount of notes with respect to each subsequent 90-day period
(or portion thereof) until all registration defaults have been cured, up to a
maximum rate of liquidated damages of 1.50% per annum of the principal amount
of notes. All

                                       28
<PAGE>

accrued liquidated damages will be paid to holders by us in the same manner as
interest is paid pursuant to the indenture. Following the cure of all
registration defaults relating to any particular transfer restricted
securities, the accrual of liquidated damages with respect to such transfer
restricted securities will cease.

Accrued Interest on the Initial Notes

   The new notes will bear interest at a rate equal to 11 1/4% per annum from
and including their date of issuance. Holders whose initial notes are accepted
for exchange will have the right to receive interest accrued thereon from the
date of their original issuance or the last interest payment date, as
applicable to, but not including, the date of issuance of the new notes. Such
interest will be payable with the first interest payment on the new notes.
Interest on the initial notes accepted for exchange, which interest accrued at
the rate of 11 1/4% per annum, will cease to accrue on the day prior to the
issuance of the new notes.

Procedures for Tendering Initial Notes

   The tender of a holder's initial notes as set forth below and the acceptance
thereof by us will constitute a binding agreement between the tendering holder
and us upon the terms and subject to the conditions set forth in this
Prospectus and in the accompanying Letter of Transmittal. Except as set forth
below, a holder who wishes to tender initial notes for exchange pursuant to the
exchange offer must transmit such initial notes, together with a properly
completed and duly executed Letter of Transmittal, including all other
documents required by such Letter of Transmittal, to the exchange agent at the
address set forth on the back cover page of this Prospectus prior to 5:00 p.m.,
New York City time, on the expiration date.

   THE METHOD OF DELIVERY OF INITIAL NOTES, LETTERS OF TRANSMITTAL AND ALL
OTHER REQUIRED DOCUMENTS IS AT THE ELECTION AND RISK OF THE HOLDER. IF SUCH
DELIVERY IS BY MAIL, IT IS RECOMMENDED THAT REGISTERED MAIL, PROPERLY INSURED,
WITH RETURN RECEIPT REQUESTED, BE USED. INSTEAD OF DELIVERY BY MAIL, IT IS
RECOMMENDED THAT THE HOLDER USE AN OVERNIGHT OR HAND DELIVERY SERVICE. IN ALL
CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE TIMELY DELIVERY.

   Each signature on a Letter of Transmittal or a notice of withdrawal, as the
case may be, must be guaranteed unless the initial notes surrendered for
exchange pursuant hereto are tendered

    (i) by a registered holder of the initial notes who has not completed
        either the box entitled "Special Exchange Instructions" or the box
        entitled "Special Delivery Instructions" in the Letter of
        Transmittal or

    (ii) by an eligible institution (as described below).

In the event that a signature on a Letter of Transmittal or a notice of
withdrawal, as the case may be, is required to be guaranteed, such guarantee
must be by a firm which is a member of a registered national securities
exchange or The Nasdaq Stock Market, a commercial bank or trust company having
an office or correspondent in the United States or otherwise be an "eligible
guarantor institution" within the meaning of Rule 17Ad-15 under the Exchange
Act. If the Letter of Transmittal is signed by a person other than the
registered holder of the initial notes, the initial notes surrendered for
exchange must either

    (i) be endorsed by the registered holder, with the signature thereon
        guaranteed by an eligible institution or

    (ii) be accompanied by a bond power, in satisfactory form as determined
         by us in our sole discretion, duly executed by the registered
         holder, with the signature thereon guaranteed by an eligible
         institution.

The term "registered holder" as used herein with respect to the initial notes
means any person in whose name the initial notes are registered on the books of
the Registrar.

                                       29
<PAGE>

   All questions as to the validity, form, eligibility (including time of
receipt), acceptance and withdrawal of initial notes tendered for exchange will
be determined by us in our sole discretion, which determination shall be final
and binding. We reserve the absolute right to reject any and all initial notes
not properly tendered and to reject any initial notes, our acceptance of which
might, in our judgment or that of our counsel, be unlawful. We also reserve the
absolute right to waive any defects or irregularities or conditions of the
exchange offer as to particular initial notes either before or after the
expiration date (including the right to waive the ineligibility of any holder
who seeks to tender initial notes in the exchange offer). The interpretation of
the terms and conditions of the exchange offer (including the Letter of
Transmittal and the instructions thereto) by us shall be final and binding on
all parties. Unless waived, any defects or irregularities in connection with
tenders of initial notes for exchange must be cured within such period of time
as we shall determine. We will use reasonable efforts to give notification of
defects or irregularities with respect to tenders of initial notes for exchange
but shall not incur any liability for failure to give such notification.
Tenders of the initial notes will not be deemed to have been made until such
irregularities have been cured or waived.

   If any Letter of Transmittal, endorsement, bond power, power of attorney or
any other document required by the Letter of Transmittal is signed by a
trustee, executor, corporation or other person acting in a fiduciary or
representative capacity, such person should so indicate when signing, and,
unless waived by us, proper evidence satisfactory to us, in our sole
discretion, of such person's authority to so act must be submitted.

   Any beneficial owner of the initial notes whose initial notes are registered
in the name of a broker, dealer, commercial bank, trust company or other
nominee and who wishes to tender initial notes in the exchange offer should
contact such registered holder promptly and instruct such registered holder to
tender on such beneficial owner's behalf. If such beneficial owner wishes to
tender directly, such beneficial owner must, prior to completing and executing
the Letter of Transmittal and tendering initial notes, make appropriate
arrangements to register ownership of the initial notes in such beneficial
owner's name. Beneficial owners should be aware that the transfer of registered
ownership may take considerable time.

   By tendering, each registered holder will represent to us that, among other
things

    (i) the new notes to be acquired in connection with the exchange offer
        by the holder and each beneficial owner of the initial notes are
        being acquired by the holder and each beneficial owner in the
        ordinary course of business of the holder and each beneficial
        owner,

    (ii) the holder and each beneficial owner are not participating, do not
         intend to participate, and have no arrangement or understanding
         with any person to participate, in the distribution of the new
         notes,

    (iii) the holder and each beneficial owner acknowledge and agree that
          any person participating in the exchange offer for the purpose of
          distributing the new notes must comply with the registration and
          prospectus delivery requirements of the Securities Act in
          connection with a secondary resale transaction of the new notes
          acquired by such person and cannot rely on the position of the
          staff of the Commission set forth in no-action letters that are
          discussed herein under "Resales of the Exchange Notes,"

    (iv) that if the holder is a broker-dealer that acquired initial notes
         as a result of market making or other trading activities, it will
         deliver a prospectus in connection with any resale of new notes
         acquired in the exchange offer,

    (v) the holder and each beneficial owner understand that a secondary
        resale transaction described in clause (iii) above should be
        covered by an effective registration statement containing the
        selling security holder information required by Item 507 of
        Regulation S-K of the Commission, and

    (vi) neither the holder nor any beneficial owner is an "affiliate," as
         defined under Rule 405 of the Securities Act, of us except as
         otherwise disclosed to us in writing.


                                       30

In connection with a book-entry transfer, each participant will confirm that it
makes the representations and warranties contained in the Letter of
Transmittal.

   Guaranteed Delivery Procedures. Holders who wish to tender their initial
notes and

    (i) whose initial notes are not immediately available or

    (ii) who cannot deliver their initial notes or any other documents
         required by the Letter of Transmittal to the exchange agent prior
         to the expiration date (or complete the procedure for book-entry
         transfer on a timely basis),

may tender their initial notes according to the guaranteed delivery procedures
set forth in the Letter of Transmittal. Pursuant to such procedures:

    (i) such tender must be made by or through an eligible institution and
        a Notice of Guaranteed Delivery (as defined in the Letter of
        Transmittal) must be signed by such holder,

    (ii) on or prior to the expiration date, the exchange agent must have
         received from the holder and the eligible institution a properly
         completed and duly executed Notice of Guaranteed Delivery (by
         facsimile transmission, mail or hand delivery) setting forth the
         name and address of the holder, the certificate number or numbers
         of the tendered initial notes, and the principal amount of
         tendered initial notes, stating that the tender is being made
         thereby and guaranteeing that, within three business days after
         the date of delivery of the Notice of Guaranteed Delivery, the
         tendered initial notes, a duly executed Letter of Transmittal and
         any other required documents will be deposited by the eligible
         institution with the exchange agent, and

    (iii) such properly completed and executed documents required by the
          Letter of Transmittal and the tendered initial notes in proper
          form for transfer (or confirmation of a book-entry transfer of
          such initial notes into the exchange agent's account at the
          depositary) must be received by the exchange agent within three
          business days after the expiration date.

Any holder who wishes to tender initial notes pursuant to the guaranteed
delivery procedures described above must ensure that the exchange agent
receives the Notice of Guaranteed Delivery and Letter of Transmittal relating
to such initial notes prior to 5:00 p.m., New York City time, on the expiration
date.

   Book-Entry Delivery. The exchange agent will establish an account with
respect to the initial notes at the depositary. Such account is the Book-Entry
Transfer Facility and will be established for purposes of the exchange offer
promptly after the date of this Prospectus. Any financial institution that is a
participant in the Book-Entry Transfer Facility's system may make book-entry
delivery of the initial notes by causing such facility to transfer initial
notes into the exchange agent's account in accordance with such facility's
procedure for such transfer. Even though delivery of initial notes may be
effected through book-entry transfer into the exchange agent's account at the
Book-Entry Transfer Facility, a properly completed and duly executed Letter of
Transmittal (or a manually signed facsimile thereof), with any required
signature guarantees, or an agent's message (as described below) in connection
with a book-entry transfer, and other documents required by the Letter of
Transmittal, must, in any case, be transmitted to and received by the exchange
agent at one of its addresses set forth on the back cover of this Prospectus
before the expiration date, or the guaranteed delivery procedure set forth
above must be followed. Delivery of the Letter of Transmittal and any other
required documents to the Book-Entry Transfer Facility does not constitute
delivery to the exchange agent. The term "agent's message" means a message
transmitted by the Book-Entry Transfer Facility to, and received by, the
exchange agent and forming a part of a book-entry confirmation, which states
that such Book-Entry Transfer Facility has received an express acknowledgment
from the participant in such Book-Entry Transfer Facility tendering the initial
notes that such participant has received and agrees to be bound by the terms of
the Letter of Transmittal and that we may enforce such agreement against such
participant.

Acceptance of Initial Notes for Exchange; Delivery of Exchange Notes

   Upon satisfaction or waiver of all the conditions to the exchange offer, we
will accept any and all initial notes that are properly tendered in the
exchange offer prior to 5:00 p.m., New York City time, on the expiration date.
The new notes issued pursuant to the exchange offer will be delivered as soon
as practicable after acceptance of the initial notes. For purposes of the
exchange offer, we shall be deemed to have accepted validly tendered initial
notes, when, as, and if we have given oral or written notice thereof to the
exchange agent.

   In all cases, issuances of new notes for initial notes that are accepted for
exchange pursuant to the exchange offer will be made only after timely receipt
by the exchange agent of such initial notes, a properly completed and duly
executed Letter of Transmittal and all other required documents (or of
confirmation of a book-entry transfer of such initial notes into the exchange
agent's account at the Depositary); provided, however, that we reserve the
absolute right to waive any defects or irregularities in the tender or
conditions of the exchange offer. If any tendered initial notes are not
accepted for any reason, such unaccepted initial notes will be returned without
expense to the tendering holder thereof as promptly as practicable after the
expiration or termination of the exchange offer.

Withdrawal Rights

   Tenders of the initial notes may be withdrawn by delivery of a written
notice to the exchange agent, at its address set forth on the back cover page
of this Prospectus, at any time prior to 5:00 p.m., New York City time, on the
expiration date. Any such notice of withdrawal must

    (i) specify the name of the person having deposited the initial notes
        to be withdrawn,

    (ii) identify the initial notes to be withdrawn (including the
         certificate number or numbers and principal amount of such initial
         notes, as applicable),

    (iii) be signed by the holder in the same manner as the original
          signature on the Letter of Transmittal by which such initial
          notes were tendered (including any required signature guarantees)
          or be accompanied by a bond power in the name of the person
          withdrawing the tender, in satisfactory form as determined by us
          in our sole discretion, duly executed by the registered holder,
          with the signature thereon guaranteed by an eligible institution
          together with the other documents required upon transfer by the
          indenture, and

    (iv) specify the name in which such initial notes are to be re-
         registered, if different from the depositor, pursuant to such
         documents of transfer.

Any questions as to the validity, form and eligibility (including time of
receipt) of such notices will be determined by us, in our sole discretion and
such determination shall be final and binding. The initial notes so withdrawn
will be deemed not to have been validly tendered for exchange for purposes of
the exchange offer. Any initial notes which have been tendered for exchange but
which are withdrawn will be returned to the holder thereof without cost to such
holder as soon as practicable after withdrawal. Properly withdrawn initial
notes may be retendered by following one of the procedures described under "The
Exchange Offer--Procedures for Tendering Initial Notes" at any time on or prior
to the expiration date.

Solicitation of Tenders; Fees and Expenses

   No person has been authorized to give any information or to make any
representation in connection with the exchange offer other than those contained
in this Prospectus. If given or made, such information or representations
should not be relied upon as having been authorized by us. Neither the delivery
of this Prospectus nor any exchange made hereunder shall, under any
circumstances, create any implication that there has been no change in our
affairs since the respective dates as of which information is given herein. The
exchange offer is not being made to (nor will offers be accepted from or on
behalf of) holders of notes in any jurisdiction in which the making of the
exchange offer or the acceptance thereof would not be in compliance with the
laws of such jurisdiction. However, we may, at our discretion, take such action
as we may deem necessary to make the exchange offer in any such jurisdiction
and extend the exchange offer to holders of notes in such jurisdiction.

   All expenses incident to our consummation of the exchange offer and
compliance with the registration rights agreement will be borne by us,
including, without limitation:

    (i) all registration and filing fees (including, without limitation,
        fees and expenses of compliance with state securities laws),

    (ii) printing expenses (including, without limitation, expenses of
         printing certificates for the new notes in a form eligible for
         deposit with the depositary and of printing Prospectuses),

    (iii) messenger, telephone and delivery expenses,

    (iv) fees and disbursements of our counsel,

    (v) fees and disbursements of independent certified public accountants,

    (vi) rating agency fees,

    (vii) our internal expenses (including, without limitation, all
          salaries and expenses of our officers and employees performing
          legal or accounting duties), and

    (viii) fees and expenses incurred in connection with the listing, if
           any, of the new notes on a securities exchange.

   We have not retained any dealer-manager in connection with the exchange
offer and will not make any payments to brokers, dealers or others soliciting
acceptance of the exchange offer. We will, however, pay the exchange agent
reasonable and customary fees for its services and will reimburse it for its
reasonable out-of-pocket expenses in connection therewith.

                                       33

Accounting Treatment

   The new notes will be recorded at the same carrying value as the initial
notes, as reflected in our accounting records on the date of the exchange.
Accordingly, no gain or loss will be recognized by us for accounting purposes.
The expenses of the exchange offer will be amortized over the term of the new
notes.

Resales of the Exchange Notes

   Based on interpretations by the staff of the Commission set forth in no-
action letters issued to third parties,we believe that the new notes issued
pursuant to the exchange offer to a holder in exchange for initial notes may be
offered for resale, resold and otherwise transferred by such holder (other than
(i) a broker-dealer who purchased initial notes directly from us for resale
pursuant to Rule 144A under the Securities Act or any other available exemption
under the Securities Act, or (ii) a person that is our affiliate within the
meaning of Rule 405 under the Securities Act) without compliance with the
registration and prospectus delivery provisions of the Securities Act, provided
that the holder is acquiring the new notes in the ordinary course of business
and is not participating, and has no arrangement or understanding with any
person to participate, in the distribution of the new notes. We have not
requested or obtained an interpretive letter from the Commission staff with
respect to this exchange offer, and we and the holders are not entitled to rely
on interpretive advice provided by the staff to other persons, which advice was
based on the facts and conditions represented in such letters. However, the
exchange offer is being conducted in a manner intended to be consistent with
the facts and conditions represented in such letters. If any holder acquires
new notes in the exchange offer for the purpose of distributing or
participating in a distribution of the new notes, such holder cannot rely on
the position of the staff of the Commission enunciated in Morgan Stanley & Co.,
Incorporated (available June 5, 1991) and Exxon Capital Holdings Corporation
(available May 13, 1988), as interpreted in the Commission's letters to
Shearman and Sterling (available July 2, 1993) and K-III Communications
Corporation (available May 14, 1993), or similar no-action or interpretive
letters and must comply with the registration and prospectus delivery
requirements of the Securities Act in connection with a secondary resale
transaction, unless an exemption from registration is otherwise available. Each
broker-dealer that receives new notes for its own account in exchange for
initial notes, where such initial notes were acquired by such broker-dealer as
a result of market making or other trading activities, must acknowledge that it
will deliver a prospectus in connection with any resale of such new notes. We
have agreed that for a period of 180 days after the effective date of this
Prospectus, we will make this Prospectus, as amended and supplemented,
available to any broker-dealer who receives new notes in the exchange offer for
use in connection with any such resale. See "Plan of Distribution."

Consequences of Failure to Exchange

   Holders of initial notes who do not exchange their initial notes for new
notes pursuant to the exchange offer will continue to be subject to the
restrictions on transfer of such initial notes as set forth in the legend
thereon as a consequence of the offer or sale of the initial notes pursuant to
an exemption from, or in a transaction not subject to, the registration
requirements of the Securities Act and applicable state securities laws. In
general, the initial notes may not be offered or sold, unless registered under
the Securities Act, except pursuant to an exception from, or in a transaction
not subject to, the Securities Act and applicable states securities laws. We do
not currently anticipate that we will register the initial notes under the
Securities Act.

Other

   Participation in the exchange offer is voluntary, and holders of initial
notes should carefully consider whether to participate. Holders of the initial
notes are urged to consult their financial and tax advisers in making their own
decisions on what action to take.

   As a result of the making of, and upon acceptance for exchange of all
validly tendered initial notes pursuant to the terms of, this exchange offer,
we will have fulfilled a covenant contained in the registration rights
agreement. Holders of initial notes who do not tender their initial notes in
the exchange offer will

                                       34
<PAGE>

continue to hold such initial notes and will be entitled to all the rights, and
limitations applicable thereto, under the indenture, except for any such rights
under the registration rights agreement that by their terms terminate or cease
to have further effectiveness as a result of the making of this exchange offer.
All untendered initial notes will continue to be subject to the restrictions on
transfer set forth in the indenture. To the extent that initial notes are
tendered and accepted in the exchange offer, the trading market for untendered
initial notes could be adversely affected.

   We may in the future seek to acquire untendered initial notes in open market
or privately negotiated transactions, through subsequent exchange offers or
otherwise. We have no present plan to acquire any initial notes which are not
tendered in the exchange offer.

   The following selected financial data should be read in conjunction with the
consolidated financial statements, the notes thereto, and with "Management's
Discussion and Analysis of Financial Condition and Results of Operations"
contained elsewhere in this prospectus. The statement of operations data from
inception to December 31, 1994, for the years ended December 31, 1995, 1996,
1997, 1998 and the balance sheet data as of December 31, 1994, 1995, 1996, 1997
and 1998 have been derived from the consolidated financial statements, which
have been audited by Deloitte & Touche LLP, independent auditors. The statement
of operations data for the three months ended March 31, 1998 and 1999, and the
balance sheet data as of March 31, 1999, have been derived from the unaudited
consolidated financial statements which, in management's opinion, include all

(1) Net revenue is after provision for bad debt.

(2) The ratio of earnings to fixed charges is computed by dividing pre-tax
    income from operations before fixed charges by fixed charges. Fixed charges
    consist of interest charges and that portion of rental expense we believe
    to be representative of interest. For the years ended December 31, 1994,
    1995, 1996, 1997 and 1998, and for the three month periods ended March 31,
    1998 and 1999, earnings were insufficient to cover fixed charges by $0.6
    million, $2.4 million, $8.6 million, $36.4 million, $63.6 million, $12.3
    million, and $25.2 million, respectively.

(3) Consists primarily of net revenue from operations in the United States for
    all periods prior to 1997. Net revenue for periods ended subsequent to the
    year ended December 31, 1996 reflects our commencement of operations in
    Canada beginning in April, 1997.

(4) Consists solely of net revenue from operations in Australia for the year
    December 31, 1996. Net revenue for periods ended subsequent to the year
    ended December 31, 1996 reflects our commencement of operations in Japan
    beginning in October 1997.

(5) Consists solely of net revenue from operations in the United Kingdom for
    all periods prior to 1998. Net revenue for periods ended subsequent to the
    year ended December 31, 1997 reflects our commencement of operations in
    Germany in August 1998.
(6) As used herein, "EBITDA" is defined as income (loss) from operations plus
    depreciation and amortization expense. While EBITDA should not be construed
    as a substitute for operating income or a better measure of liquidity than
    cash flow from operating activities, which are determined in accordance
    with generally accepted accounting principles, it is included to provide
    additional information regarding our ability to meet future debt service,
    capital expenditures and working capital requirements. EBITDA is not
    necessarily a measure of our ability to fund our cash needs and is not
    necessarily comparable to similarly titled measures of other companies.
(7) Capital expenditures excludes assets acquired in business combinations and
    under terms of capital leases.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

   The following discussion and analysis should be read in conjunction with the
applicable consolidated financial statements and notes thereto contained
elsewhere in this prospectus.

Overview

   We are a facilities-based global telecommunications company offering
international and domestic long distance and other telecommunications services
to business, residential and carrier customers. Our customers are primarily in
North America, Europe and selected markets within both the Asia-Pacific region.
We seek to capitalize on the increasing demand for high-quality international
telecommunications services. The globalization of the world's economies, the
worldwide trend toward telecommunications deregulation and the growth of data
and Internet traffic fuels this demand. We provide services over our
telecommunications network, which consists of (i) 19 carrier-grade switches,
including 15 international gateway switches in the United States, Australia,
Canada, Germany, Japan, Puerto Rico and the United Kingdom, (ii) four domestic
switches in Australia, (iii) more than 100 POPs and Internet access nodes
within our principal servicer regions, (iv) both owned and leased transmission
capacity on undersea and land-based fiber optic cable systems and (v) an
international satellite earth station located in London, together with the
capacity we leased on an Intelsat satellite. Utilizing this network, along with
resale arrangements and foreign carrier agreements, we offer quality service to
approximately 1.7 million customers.

   We were founded in February 1994, and through the first half of 1995 we were
a development stage enterprise involved in various start-up activities. These
activities included:

    .  raising capital,

    .  obtaining licenses,

    .  acquiring equipment,

    .  leasing space,

    .  developing markets and

    .  recruiting and training personnel.

We began generating revenue during March 1995. On March 1, 1996 we acquired
Axicorp Pty. Ltd., the fourth largest telecommunications provider in Australia.
The Axicorp acquisition had a material effect on our results of operations for
the year ended December 31, 1996. Our Australian operations generated
approximately $177.6 million, or 89%, of our pro forma net revenue for the year
ended December 31, 1996 assuming the Axicorp acquisition had occurred on
January 1, 1996.

   We have invested substantial resources to transform Axicorp's strategy and
operations to those of a facilities-based carrier focused on the provision of
international and domestic long distance services. Prior to the acquisition,
Axicorp was a reseller of long distance, local and cellular service and did not
own any switches. Since the Axicorp acquisition, we have installed and begun to
carry traffic on a five-switch network in Australia, have leased fiber capacity
connecting Australia with the United States and, in July 1997, became one of
the initial five licensed carriers permitted to own and operate transmission
facilities in Australia. We have focused on migrating existing traffic onto our
network while increasing the number of higher-margin, higher-volume business
customers with significant international long distance traffic. As part of our
focus on business customers, we have increased Axicorp's direct sales force and
reduced its reliance on marketing through trade and professional associations.
We have experienced and expect to continue to experience lower gross margin as
a percentage of net revenue for Axicorp's local switched and cellular services,
as compared to long distance services. We expect to continue to upgrade
Axicorp's facilities, increase its traffic capacity and introduce new products
and services. In that regard, we expanded our service offerings in Australia
with our

                                       43
<PAGE>

March 1998 acquisition of a controlling interest in Hotkey Internet Services
Pty. Ltd., an Australia-based Internet service provider, our April 1998
acquisition of all the outstanding stock of Eclipse Telecommunications Pty.
Ltd., an Australia-based data communications service provider and our February
1999 acquisition of the remaining interest in Hotkey.

   On June 9, 1998, we acquired the operations of TresCom. After giving pro
forma effect to the TresCom merger, for the year ended December 31, 1998, we
would have had net revenue of $485.2 million. The TresCom merger expands the
scope and coverage of our telecommunications network, thereby providing
additional opportunities to migrate traffic onto the network, resulting in
better utilization of the network and reduced variable costs.

   In September 1998, we announced a refinement of our strategic outlook. The
principal element of the revised strategy includes concentrating our immediate
expansion plans in those markets that are more economically stable and are
experiencing more rapid deregulation, such as continental Europe and Canada.
Thereafter, we plan to expand in additional markets within our principal
service regions, including Japan, other parts of the Asia-Pacific region and
Latin America. As part of the refined strategy, we announced our intention to
continue the development of our retail customer base in the United States, the
United Kingdom and Australia, and to build the infrastructure to expand our
retail customer base in select European countries (focusing on Germany in the
immediate future). Finally, the refined strategy, as announced, also includes
greater focus on data and Internet services.

   We began our implementation of this refined strategy by:

  .  acquiring London Telecom, a Canadian long distance provider, and certain
     related companies;

  .  purchasing a residential long distance customer base, customer support
     assets and residential Internet customers and network from AT&T Canada
     and ACC Telenterprises;

  .  purchasing Telegroup's global retail customer businesses, which include
     retail customers primarily in North America and Europe; and

  .  organizing our Internet and data services business into a new
     subsidiary, iPRIMUS.com, and acquiring GlobalServe, a Canadian ISP,
     TCP/IP GmbH, an independent German ISP, and the remaining interest in
     Hotkey Internet Services.

   Net revenue is earned based on the number of minutes billable and is
recorded upon completion of a call, adjusted for sales allowance. We generally
price our services at a savings compared to the major carriers operating in our
principal service regions. Our net revenue is derived from carrying a mix of
business, residential and carrier long distance traffic, data and Internet
traffic in Australia and Canada, and, in Australia, also from the provision of
local and cellular services. We expect to continue to generate net revenue from
internal growth through sales and marketing efforts focused on customers with
significant international long-distance usage, including small- and medium-
sized businesses, multinational corporations, ethnic residential customers and
other telecommunications carriers and resellers.

   Prices in the long distance industry in the United States and the United
Kingdom have declined in recent years and, as competition continues to
increase, we believe that prices are likely to continue to decrease.
Additionally, we believe that because deregulatory influences only recently
have begun to affect non-United States and non-United Kingdom
telecommunications markets, including Australia, the deregulatory trend in such
markets is expected to result in greater competition which could adversely
affect our net revenue per minute and gross margin as a percentage of net
revenue. However, we believe that such decreases in prices will be at least
partially offset by increased telecommunications usage and decreased costs.

   Cost of revenue is primarily comprised of costs incurred from other domestic
and foreign telecommunications carriers to originate, transport and terminate
calls. The majority of our cost of revenue is variable, based upon the number
of minutes of use, with transmission and termination costs being our most
significant expense. As we increase the portion of traffic transmitted over
leased or owned facilities, cost of

                                       44
<PAGE>

revenue increasingly will be comprised of fixed costs. In order to manage such
costs, we pursue a flexible approach with respect to the expansion of our
network. In most instances, we initially obtain transmission capacity on a
variable-cost, per-minute leased basis, next acquire additional capacity on a
fixed-cost basis when traffic volume makes such a commitment cost-effective,
and ultimately purchase and operate our own facilities when traffic levels
justify such investment. We also seek to lower our cost of revenue through (i)
optimizing the routing of calls over the least cost route, (ii) increasing
volumes on our fixed cost leased and owned lines, thereby spreading the
allocation of fixed costs over a larger number of minutes, (iii) negotiating
lower variable usage based costs with domestic and foreign service providers
and negotiating additional and lower cost foreign carrier agreements with the
foreign incumbent carriers and others, and (iv) continuing to expand the
network when we believe traffic volumes justify such investment.

   We generally realize a higher gross margin as a percentage of net revenue on
our international as compared to our domestic long distance services and a
higher gross margin as a percentage of net revenue on our services to both
business and residential customers compared to those realized on our services
to other telecommunications carriers. In addition, we generally realize a
higher gross margin as a percentage of net revenue on our long distance
services as compared to those realized on local switched and cellular services.
Carrier services, which generate a lower gross margin as a percentage of net
revenue than retail services, are an important part of our net revenue because
the additional traffic volume of such carrier customers improves the
utilization of the network and allows us to obtain greater volume discounts
from our suppliers than we otherwise would realize. Our overall gross margin as
a percentage of net revenue may fluctuate based on our relative volumes of
international versus domestic long distance services, carrier services versus
business and residential long distance services, and the proportion of traffic
carried on our network versus resale of other carriers' services.

   Our selling, general and administrative expenses are comprised primarily of
salaries and benefits, commissions, occupancy costs, sales and marketing
expenses, advertising and administrative costs. These expenses have been
increasing consistent with the expansion of our operations and the
transformation of both Axicorp's and TresCom's operations. We expect this trend
to continue and believe that we will incur additional selling, general and
administrative expenses to support the expansion of sales and marketing efforts
and operations in current markets as well as new markets in our principal
service regions.

   Since the inception of our operations, we have made, and expect to continue
to make, significant investments in the development of our operations in our
principal service regions and the development and expansion of our network. The
costs of developing our operations and expanding our network, including the
purchase and installation of switches, sales and marketing expenses and other
organizational costs, are significant. In addition, our increased capital
investment activity in the future can be expected to affect our operating
results in the near term due to increased depreciation charges and interest
expense in connection with borrowings to fund such expenditures. These costs
will be incurred in advance of the realization of the expected improvements in
operating results from such investments. Such costs and investment activities
have resulted in negative cash flows and operating losses for us on an
historical basis, which are expected to continue in the near future as we use
the proceeds from the notes to accelerate the expansion of our business and the
build-out of our network.

   Although our functional currency is the United States dollar, a significant
portion of our net revenue is derived from sales and operations outside the
United States. In the future, we expect to continue to derive the majority of
our net revenue and incur a significant portion of our operating costs from
outside the United States and therefore changes in exchange rates may have a
significant effect on our results of operations. We historically have not
engaged in hedging transactions and do not currently contemplate engaging in
hedging transactions to mitigate foreign exchange risks.

   Other Financial and Operating Data. The following financial and operating
data for the 11 quarters ended March 31, 1999 is provided for informational

Results of Operations

 For the three months ended March 31, 1999 as compared to the three months
 ended March 31, 1998

   Net revenue increased $51.1 million or 64%, from $80.1 million for the three
months ended March 31, 1998 to $131.2 million for the three months ended March
31, 1999. Of the increase, $35.9 million was associated with our North American
operations, which represents a growth rate of 136%. The growth reflects
increased traffic volumes in business and ethnic residential retail operations
and in carrier operations, and includes operations of TresCom in the 1999
results. Our European net revenue increased $15.5 million from $9.1 million for
the three months ended March 31, 1998 to $24.6 million for the three months
ended March 31, 1999, a growth rate of 171%. Our European net revenue increase
is attributable to increased traffic volumes in business and residential retail
traffic operations, the addition of carrier operations in the United Kingdom
and the addition of carrier and retail operations in Germany. Our Asia-Pacific
net revenue decreased slightly from $44.7 million for the three months ended
March 31, 1998 to $44.4 million for the three months ended March 31, 1999. Our
Asia-Pacific net revenue decrease in United States dollar terms is a result of
7% decrease in the Australian dollar's average exchange rate period over
period. Net revenue of the Australian operations, in Australian dollar terms,
grew as a result of increased traffic from retail residential and business
customers and from the addition of data and Internet services.

   Cost of revenue increased $35.9 million, from $68.7 million, or 85.8% of net
revenue, for the three months ended March 31, 1998 to $104.6 million, or 79.7%
of net revenue, for the three months ended March 31, 1999. The increase in the
cost of revenue is attributable to the increase in traffic volumes and
associated net revenue growth. Our cost of revenue as a percentage of net
revenue decreased by 610 basis points as a result of the continuing expansion
of our global network, a greater mix of retail versus carrier traffic, the
continuing migration of existing and newly generated customer traffic onto our
network and new higher margin product offerings such as data and Internet
services.

   Selling, general and administrative expenses increased $13.9 million, from
$15.4 million for the three months ended March 31, 1998, to $29.3 million for
the three months ended March 31, 1999. The increase is attributable to the
addition of expense from acquired operations, including TresCom and GlobalServe
Communications Inc. and increased advertising and promotional expenses
associated with our retail marketing campaigns.

   Depreciation and amortization expense increased from $3.5 million for the
three months ended March 31, 1998 to $9.0 million for the three months ended
March 31, 1999. The increase is associated with increased amortization expense
related to intangible assets arising from our acquisitions of TresCom,
GlobalServe and Hotkey, and from increased depreciation expense related to
capital expenditures for fiber optic cable, switching and other network
equipment being placed into service.

   Interest expense increased from $7.2 million for the three months ended
March 31, 1998 to $16.8 million for the three months ended March 31, 1999. The
increase is primarily due to the additional debt incurred pursuant to the
January 1999 senior notes and, to a lesser extent, additional capital lease
financings.

   Interest income increased from $2.4 million for the three months ended March
31, 1998 to $3.3 million for the three months ended March 31, 1999. The
increase is a result of the investment of the net proceeds from our January
1999 senior notes offering.

 For the year ended December 31, 1998 as compared to the year ended December
 31, 1997

   Net revenue increased $141.4 million or 51% to $421.6 million for the year
ended December 31, 1998, from $280.2 million for the year ended December 31,
1997. Of the net revenue increase, $113.7 million was associated with our North
American operations, which represents a growth rate of approximately 153%. The
growth reflects increased traffic volumes in business and ethnic residential
retail operations and in carrier operations, and includes operations of TresCom
(since the June 9, 1998 acquisition), and a full year's results of

                                       47
<PAGE>

the acquired Canadian operations and the acquired operations of TelePassport
L.L.C./USFI, Inc. Our European net revenue increased from $22.7 million for the
year ended December 31, 1997 to $60.9 million for the year ended December 31,
1998, resulting from increased retail business and residential traffic and the
addition of carrier services, both in the United Kingdom and Germany. Our Asia-
Pacific net revenue decreased by $10.3 million or 5.7% to $172.8 million for
the year ended December 31, 1998 from $183.1 million for the year ended
December 31, 1997 primarily resulting from a 13% decrease in the Australian
dollar average exchange rate. Net revenue of the Australian operations, in
Australian dollar terms, grew 7% to Australian $259.5 million as a result of
increased retail business and residential traffic growth and the addition of
data and Internet services.

   Cost of revenue increased $100.3 million, from $252.7 million, or 90.2% of
net revenue, for the year ended December 31, 1997 to $353.0 million, or 83.7%
of net revenue, for the year ended December 31, 1998. The increase in the cost
of revenue is primarily attributable to the increased traffic volumes and
associated net revenue growth. The cost of revenue as a percentage of net
revenue decreased by 650 percentage points as a result of the expansion of our
global network, the continuing migration of existing and newly generated
customer traffic onto our network, and new higher margin product offerings such
as data and Internet services.

   Selling, general and administrative expenses increased $28.9 million to
$79.5 million for the year ended December 31, 1998 from $50.6 million for the
year ended December 31, 1997. The increase is attributable to the addition of
expenses from acquired operations including TresCom, Hotkey, Eclipse and the
Canadian operations, the hiring of additional sales and marketing staff and
network operations personnel and increased advertising and promotional expenses
associated with our residential marketing campaigns.

   Depreciation and amortization increased from $6.7 million for the year ended
December 31, 1997 to $24.2 million for the year ended December 31, 1998. The
increase is associated with increased amortization expense related to
intangible assets arising from our acquisitions and with increased depreciation
expense related to capital expenditures for fiber optic cable, switching and
other network equipment being placed into service.

   Interest expense increased to $40.0 million for the year ended December 31,
1998 from $12.9 million for the year ended December 31, 1997. The increase is
primarily attributable to the interest expense associated with our August 1997
$225 million 11 3/4% senior notes offering, due 2004, and our May 1998 $150
million 9 7/8% senior notes offering, due 2008, and, to a lesser extent, our
Bank Revolving Credit Facility and additional capital lease financing.

   Interest income increased from $6.2 million for the year ended December 31,
1997 to $11.5 million for the year ended December 31, 1998. The increase is a
result of the investment of the net proceeds of our 1998 and 1997 Senior Note
offerings.

 For the year ended December 31, 1997 as compared to the year ended December
 31, 1996

   Net revenue increased $107.2 million or 62%, from $173.0 million for the
year ended December 31, 1996 to $280.2 million for the year ended December 31,
1997 (the net revenue increase in 1997 was $80.9 million or 40.6% when compared
to our net revenue during 1996 after giving pro forma effect to the acquisition
of Axicorp as of January 1, 1996). Of the increase, $57.8 million was
associated with our North American operations and reflects a growth rate of
approximately 350% (approximately 300% exclusive of net revenue associated with
the TelePassport/USFI acquisition and operations acquired in Canada during
1997). The growth is a result of increased traffic volumes in wholesale carrier
operations and, to a lesser extent, in ethnic residential and business customer
traffic. The Asia-Pacific operations contributed $31.9 million to the year-
over-year net revenue growth, resulting primarily from the residential customer
marketing campaigns commenced in early 1997. The 1997 results also reflect a
full year of the Australian operations as compared to ten months in 1996 as a
result of the March 1, 1996 acquisition of these operations. The Asia-Pacific
net revenue growth was negatively impacted by weakness in the Australian dollar
during 1997 as compared to 1996. The remaining net revenue growth of $17.6
million, a year-over-year growth rate in excess of 300%,

                                       48
<PAGE>

came from the European operations as a result of expansion into the wholesale
carrier marketplace during the third quarter of 1997 and continued growth in
the ethnic residential and business marketplaces.

   Cost of revenue increased $93.9 million, from $158.8 million, or 91.8% of
net revenue, for the year ended December 31, 1996 to $252.7 million, or 90.2%
of net revenue, for the year ended December 31, 1997. The increase in the cost
of revenue is a direct reflection of the increase in traffic volumes. The
decrease in the cost of revenue as a percentage of net revenue reflects our
investments in the network and the associated migration of customer traffic
onto our Network, particularly in Australia with the introduction of equal
access in the second half of 1997.

   Gross margin increased $13.3 million, from $14.1 million, or 8.2% of net
revenue, for the year ended December 31, 1996 to $27.5 million, or 9.8% of net
revenue, for the year ended December 31, 1997.

   Selling, general and administrative expenses increased $30.5 million, from
$20.1 million or 11.6% of net revenue for the year ended December 31, 1996 to
$50.6 million or 18.1% of net revenue for the year ended December 31, 1997, as
compared to the year ended December 31, 1996 (the increase in 1997 was $28.4
million when compared to our selling, general and administrative expenses
during 1996 after giving pro forma effect to the acquisition of Axicorp as of
January 1, 1996). The increase is attributable to the hiring of additional
sales and marketing staff, additional operations and engineering personnel to
operate our network; the TelePassport/USFI acquisition and operations acquired
in Canada during 1997; a full year of our Australian operations versus ten
months in the prior year; and increased advertising and promotional expenses
associated with our residential marketing campaigns.

   Depreciation and amortization increased $4.5 million or 211.1%, from $2.2
million for the year ended December 31, 1996 to $6.7 million for the year ended
December 31, 1997. The majority of the increase is associated with capital
expenditures for international fiber, telephone switches and related
transmission equipment being placed into service. Additionally, amortization
expense increased as a result of the additional intangible assets associated
with our acquisitions during 1997.

   Interest expense increased $12.0 million, from $0.9 million for the year
ended December 31, 1996 to $12.9 million for the year ended December 31, 1997.
The increase is attributable to the interest expense associated with our 1997
Senior Notes issued in August 1997.

   Interest income increased $5.4 million, from $0.8 million for the year ended
December 31, 1996 to $6.2 million for the year ended December 31, 1997. The
increase is due to investment of the proceeds from our 1997 Senior Notes
offering and our initial public equity offering.

   Other income (expense) for the year ended December 31, 1997 was $0.4 million
compared to an expense of $0.3 million for the year ended December 31, 1996.
Other income (expense) is the result of foreign currency transaction
gains/losses on Australian dollar-denominated debt incurred by us for the
acquisition of Axicorp, due to the fluctuations of the Australian dollar
against the United States dollar during the year. This debt was paid in full
during 1997.

   Income taxes were attributable to the operations of our United Kingdom and
Australian subsidiaries.

Liquidity and Capital Resources

   Our liquidity requirements arise from:

    .  net cash used in operating activities;

    .  purchases of network equipment including switches, related
       transmission equipment, international and domestic fiber cable
       capacity, satellite earth stations and satellite transmission
       capacity;

                                       49
<PAGE>


    .  interest and principal payments on outstanding indebtedness; and

    .  acquisitions of and strategic investments in businesses.

   We have financed our growth to date through public offerings and private
placements of debt and equity securities, bank debt and capital lease
financing.

   Net cash used in operating activities was $30.2 million for the three months
ended March 31, 1999 as compared to net cash used in operating activities of
$17.1 million for the three months ended March 31, 1998. The increase in
operating cash used is comprised primarily of an increase in net losses of
$12.8 million.

   Net cash used in operating activities was $71.3 million for the year ended
December 31, 1998 as compared to net cash used in operating activities of $14.8
million for the year ended December 31, 1997 and $6.9 million for the year
ended December 31, 1996. The increase in cash used in operating activities for
the year ended December 31, 1998 as compared to the year ended December 31,
1997 is primarily comprised of an increase in net losses of $27.4 million and a
decrease in accounts payable of $8.2 million (as compared to an increase in
accounts payable of $30.2 million in 1997), partially offset by increased non-
cash operating expenses of $21.5 million. The increase in cash used in
operating activities for the year ended December 31, 1997 was primarily the
result of the increase in the negative operating cash flow for the period as
compared to the same period in 1996. The increased cash usage for the year
ended December 31, 1996 was the result of an increase in net losses partially
offset by increases in accounts payable and accrued expenses.

   Net cash used in investing activities was $11.6 million for the three months
ended March 31, 1999 compared to net cash used in investing activities of $0.9
million for the three months ended March 31, 1998. Net cash used in investing
activities during the three months ended March 31, 1999 includes $16.4 million
of capital expenditures primarily for the expansion of our global network, $7.8
million for business acquisitions, partially offset by $12.6 million of cash
provided by the sale of restricted investments used to fund interest payments
on the 1997 senior notes.

   Net cash used in investing activities was $54.2 million for the year ended
December 31, 1998 compared to net cash used in investing activities of $104.2
million for the year ended December 31, 1997 and $39.6 million for the year
ended December 31, 1996. Net cash used in investing activities during the year
ended December 31, 1998 includes $76.0 million of capital expenditures
primarily for the expansion of our global network, partially offset by $22.9
million of cash provided by the sale of restricted investments used to fund
interest payments on the 1997 Senior Notes. Cash used in investing activities
for the year ended December 31, 1997 was the result of capital expenditures
made during the year of $39.5 million to expand our global network, the
TelePassport/USFI acquisition and the acquisition of our Canadian operations
net of cash acquired, and the purchase of $73.6 million of restricted
investments with proceeds from the offering of the 1997 Senior Notes for
escrowed interest payments, offset by the sale of $25.1 million of short term
cash investments. The cash utilized during the year ended December 31, 1996
includes $12.7 million for capital expenditures to expand our global network
and $1.7 million for the purchase of Axicorp, net of cash acquired.

   Net cash provided by financing activities was $173.7 million for the three
months ended March 31, 1999 as compared to net cash provided by financing
activities of $0.1 million during the three months ended March 31, 1998. Cash
provided by financing activities in the three months ended March 31, 1999
resulted primarily from $192.5 million of net proceeds of the January 1999
senior notes offering, offset by the $17.8 million repayment of a bank
revolving credit agreement.

   Net cash provided by financing activities was $146.8 million for the year
ended December 31, 1998 as compared to net cash provided by financing
activities of $200.1 million during the year ended December 31, 1997 and $79.5
million during the year ended December 31, 1996. Cash provided by financing
activities in the year ended December 31, 1998 resulted primarily from $144.5
million of net proceeds of the 1998 Senior Notes offering. Net cash provided by
financing activities for the year ended December 31, 1997 resulted rimarily
from the net proceeds of the offering of 1997 Senior Notes. In 1996, we
completed private placements

                                       50
<PAGE>

of Common Stock generating net proceeds of approximately $21.9 million, and in
November 1996, we completed an initial public offering of our Common Stock and
generated net proceeds of approximately $54.4 million.

   We anticipate aggregate capital expenditures of approximately $60 million
during the remainder of 1999. Such capital expenditures will be primarily for
international and domestic switches and POPs, international and domestic fiber
optic cable capacity for new and existing routes, satellite earth station
facilities, other transmission equipment, and back office support systems. We
recently installed an additional international gateway switch in Paris, which
became operational during the third quarter of 1999. By the end of 2000, we
intend to add up to one switch in North America, 11 additional switches in
Europe and one switch in Japan.

   In January 1999, we entered into a supplemental indenture applicable to our
1997 senior notes in order to provide additional flexibility to incur
indebtedness to fund our expansion, to make permitted investments in marketing
channels and complementary telecommunications services and to secure additional
bank debt. The supplemental indenture substantially conformed certain covenants
applicable to the 1997 senior notes to the corresponding provisions of our
other senior notes. We incurred fees and expenses of approximately $4.8 million
in connection with securing consents to enter into the supplemental indenture.

   In January 1999, we voluntarily repaid in full with a part of our available
cash, and delivered notice of our termination of, the TresCom credit facility.
The TresCom credit facility, which provided for up to $25 million of revolving
credit borrowings and which was due to mature on July 30, 2002, was acquired
from TresCom upon the completion of the TresCom merger. In March 1999, the
TresCom credit facility was terminated and we will no longer be able to borrow
funds under it. The collateral securing the repayment obligations, consisting
primarily of TresCom's receivables, has been released. We do not believe that
the termination of the TresCom credit facility will have a material adverse
effect on our liquidity and capital resources.

   In January 1999, we completed the offering of $200 million 11 1/4% senior
notes due in 2009 which are being exchanged hereby. The $192.5 million of net
proceeds of the January 1999 unregistered senior notes offering are to be used
for continued expansion of our network and other general corporate purposes.
The indenture under which these notes were issued permits us to issue up to $75
million in additional notes of the same series, subject to the debt incurrence
provisions thereunder.

   In March 1999, we purchased the common stock of London Telecom and certain
related entities that provide long distance telecommunications services in
Canada, for approximately C$54 million in cash (including payments made in
exchange for certain non-competition agreements). In May 1999, we purchased
substantially all of the operating assets of Wintel CNC Communications, Inc.
and Wintel CNT Communications, Inc., which are Canada-based long distance
telecommunications providers affiliated with the London Telecom companies, for
C$22 million in cash.

   In June 1999, we purchased Telegroup's global retail customer business,
including the acquisition of selected foreign subsidiaries. We paid the $71.8
million purchase price, plus $22.2 million for certain current assets, by
issuing under the January 1999 indenture, an additional $45.5 million aggregate
principal amount of our 11 1/4% senior notes due 2009, by issuing a $4.6
million short-term promissory note and by paying $43.9 million in cash.

   In May 1999, we purchased the residential long distance customer base,
consumer support assets and residential Internet customers and network from
AT&T Canada and ACC Telenterprises for C$58.1 million.

   In May 1999, we acquired TCP/IP GmbH, an independent German ISP. TCP/IP
operates the Contrib.Net Internet backbone. Our newly formed subsidiary,
iPRIMUS.com, will operate TCP/IP's Internet backbone.

   We believe that the net proceeds from the notes to be exchanged, together
with our existing cash and available capital lease financing and bank financing
(subject to limitations in the 1999 indenture, the 1997

                                       51
<PAGE>


indenture and 1998 indenture) will be sufficient to fund our operating losses,
debt service requirements, capital expenditures and other cash needs for our
operations for at least the next 12 months. The semi-annual interest payments
due under the 1997 senior notes through August 1, 2000 have been pre-funded and
will be paid from our restricted investments. We are continually evaluating the
expansion of our service offerings and plan to make further investments in and
enhancements to our switches and distribution channels in order to expand our
service offerings. In order to fund these additional cash requirements, we
anticipate that we will be required to raise additional financing from public
or private equity or debt sources. Additionally, if our plans or assumptions
change (including those with respect to the development of our network, the
level of our operations and our operating cash flow), if our assumptions prove
inaccurate, if we consummate additional investments or acquisitions or if we
experience unexpected costs or competitive pressures, or if existing cash and
any other borrowings prove to be insufficient, we may be required to seek
additional capital sooner than expected.

   Since our inception through March 31, 1999, we have had negative cash flow
from operating activities of $125.7 million and negative EBITDA of $45.5
million. In addition, we incurred net losses in 1995, 1996, 1997, 1998 and the
three months ended March 31, 1999 of $2.4 million, $8.8 million, $36.2 million,
$63.6 million and $25.2 million, respectively, and had an accumulated deficit
of approximately $136.8 million as of March 31, 1999. On a pro forma basis,
after giving effect to the offering of the 1998 senior notes, the January 1999
senior notes, the TresCom merger and the Telegroup acquisition, including the
issuance of $45.5 million of senior notes and a $4.6 million short-term
promissory note in connection with the Telegroup acquisition, for the year
ended December 31, 1998, we would have had a net loss of $167.4 million. On a
pro forma basis, after giving effect to the January 1999 senior notes and the
Telegroup acquisition, including the issuance of $45.5 million of senior notes
and a $4.6 million short-term promissory note in connection with the Telegroup
acquisition, for the three months ended March 31, 1999, we would have had a net
loss of $32.3 million. Although we have experienced net revenue growth in each
of our last 16 quarters, such growth should not be considered to be indicative
of future net revenue growth, if any. We expect to continue to incur additional
operating losses and negative cash flow from operations as we expand our
operations and continue to build-out and upgrade our network. There can be no
assurance that our revenue will grow or be sustained in future periods or that
we will be able to achieve or sustain profitability or positive cash flow from
operations in any future period. If we cannot achieve and sustain operating
profitability or positive cash flow from operations, we may not be able to meet
our debt service or working capital requirements (including our obligations
with respect to the notes).

   From time to time we evaluate acquisitions, joint ventures and strategic
investments involving businesses which complement our business. Depending on
the cash requirements of potential transactions, we may finance such
transactions with bank borrowings, through other debt financing vehicles, or
through the issuance of capital stock. However, we presently have no commitment
or agreement with respect to any material acquisition, joint venture or
strategic investment. There can be no assurance that if we were to pursue such
an opportunity, any such transaction would occur or that the funds to finance
any such transaction would be available on reasonable terms, if at all.

Quantitative and Qualitative Disclosures About Market Risk

   The Company's primary market risk exposures relate to changes in foreign
currency exchange rates and to changes in interest rates.

   Foreign currency. Although the Company's functional currency is the United
States dollar, a significant portion of the Company's net revenue is derived
from its sales and operations outside the United States. In the future, the
Company expects to continue to derive a significant portion of its net revenue
and incur a significant portion of its operating costs outside the United
States, and changes in foreign currency exchange rates may have a significant
effect on the Company's results of operations. The operations of affiliates and
subsidiaries in foreign countries have been funded with investments and other
advances. Due to the long-term nature of such investments and advances, the
Company accounts for any adjustments resulting from translation as a charge or
credit to "accumulated other comprehensive loss" within the stockholders'
equity section of the consolidated balance sheet. The Company historically has
not engaged in hedging transactions.

                                       52
<PAGE>


   Interest rates. The Company's financial instruments that are sensitive to
changes in interest rates are its (i) 1997 $225 million 11 3/4% senior notes
due August 2004, (ii) 1998 $150 million 9 7/8% senior notes due May 2008, and
(iii) 1999 $200 million 11 1/4% senior notes due 2009. As of March 31, 1999,
the aggregate fair value of the 1997, 1998 and 1999 senior notes approximates
their face value.

Year 2000 Compliance

   General. We are reviewing our network elements, computer systems, software
applications and other business systems in order to determine if any of these
systems will not properly reflect or recognize the year 2000. Because many
computer and computer applications define dates by the last two digits of the
year, "00" could be interpreted to mean the year 1900, rather than the year
2000. This error could result in miscalculations or system failures. Year 2000
issues may also affect the systems and applications of our customers, vendors
or resellers.

   Compliance Program. In 1998, we began a comprehensive inventory and Year
2000 assessment of our principal computer systems, network elements, software
applications and other business systems throughout the world. We have completed
our inventory and assessment and have begun repairing or replacing the most
critical items that we have determined not to be Year 2000 compliant. We expect
to complete the repair, replacement, testing and certification of substantially
all non-compliant network elements by September 30, 1999. We are using both
internal and external resources to identify, correct or reprogram, and test our
systems for Year 2000 compliance.

   Suppliers. We are currently and have been contacting third party suppliers
of major equipment, software, systems and services used by us to identify and,
to the extent possible, to resolve issues involving Year 2000 compliance.
However, we have limited or no control over the actions of these third party
suppliers. Consequently, while we expect that we will be able to resolve any
significant Year 2000 issues with regard to these systems and services, there
can be no assurance that these suppliers will resolve any or all Year 2000
issues before the occurrence of a material disruption to our business or any of
our customers.

   Costs. We expect to incur in the aggregate approximately $3 to $5 million in
expenditures in 1999 to complete our Year 2000 compliance program. These
estimates do not include the costs of systems, software and equipment that are
being replaced or upgraded in the normal course of business. The costs of
modifying our network elements, software and systems for Year 2000 compliance
are being funded from existing cash resources and are being charged as expenses
as incurred.

   Risks. We believe that we will substantially complete the implementation of
our Year 2000 program prior to December 31, 1999. Consequently, we do not
believe that Year 2000 issues will have a material adverse effect on our
business or results of operations. However, if we do not achieve compliance
prior to December 31, 1999, if we fail to identify and remedy all critical Year
2000 problems or if major suppliers or customers experience material Year 2000
problems, our results of operations or financial condition could be materially
affected. We have determined that non-compliant network elements may result in
improperly routed traffic and that non-compliant, non-network systems may
result in errors in customer billing and accounting records.

   Contingency Plans. We have begun to develop appropriate contingency plans to
mitigate, to the extent possible, any significant Year 2000 noncompliance. We
expect to complete our contingency plans by September 30, 1999. If we are
required to implement our contingency plans, the cost of Year 2000 compliance
may be greater than the amount referenced above and there can be no assurance
that these plans will be adequate.

   We are a facilities-based global telecommunications company. We offer
international and domestic long distance and other telecommunications services
to business, residential and carrier customers located in North America, Europe
and selected markets in the Asia-Pacific region. We seek to capitalize on the
increasing demand for high-quality international telecommunications services
which is being driven by the globalization of the world's economies, the
worldwide trend toward telecommunications deregulation and the growth of global
data and Internet traffic. We provide services over our network, which
includes:

  .  15 international gateway switches in the United States, Australia,
     Canada, Germany, Japan, Puerto Rico and the United Kingdom;

  .  four domestic switches in Australia;

  .  both owned and leased transmission capacity on undersea and land-based
     fiber optic cable systems; and

  .  an international satellite earth station located in London.

   Utilizing our network, along with resale arrangements and foreign carrier
agreements, we offer quality service to approximately 1.7 million customers.

   We are a full-service carrier with operations in the United States, Canada,
Australia, the United Kingdom, Germany, France, Switzerland, the Netherlands,
Denmark, Italy, Japan and Hong Kong. We had net revenue and pro forma net
revenue, after giving effect to our merger with Trescom International, Inc. and

</TABLE>

   We primarily target customers with significant international long distance
usage, including

  .  small- and medium-sized businesses;

  .  multinational corporations;

  .  ethnic residential customers; and

  .  other telecommunications carriers and resellers.

   Through our newly formed subsidiary, iPrimus.com, we are also increasingly
targeting business and residential customers for data and Internet services.

   In an effort to attract larger business customers in multiple markets, we
intend to offer a broad array of services (including long distance voice,
cellular, Internet and data services) in approximately 10 major markets,
including the United States, Canada, Australia, the United Kingdom, Germany,
France, Japan and Italy. We provide competitively priced telecommunications
services, including:

  .  international and domestic long distance services and private networks;

  .  prepaid and calling cards, toll-free services and reorigination
     services;

  .  local services in Australia, Canada, Puerto Rico and the United States
     Virgin Islands;

  .  data, Internet and cellular services in Australia; and

  .  Internet services in Canada and Germany.

   We market our services through a variety of channels, including through our
direct sales force, independent agents and direct marketing.

   By constructing and expanding our network, we reduced costs, improved
service reliability and increased flexibility to introduce new products and
services. By carrying more traffic over our expanding network, we have
increased gross margin as a percentage of net revenue (after accounting for bad
debt) to 20.3% in the first quarter of 1999 from 6.8% in the first quarter of
1997. We believe that, as the volume of telecommunications traffic carried on
our network increases, we should continue to improve profitability as we more
fully utilize our network capacity and realize economies of scale. Currently,
29 countries are connected directly to our network. We expect to continue to
expand our network through additional investment in undersea and domestic fiber
optic cable systems, international gateway and domestic switching facilities
and international satellite earth stations as customer demand justifies the
capital investment. Major components of our network include the following:

   Switches and Points of Presence. Our network consists of 19 carrier-grade
switches, including 15 international gateway switches and four domestic
switches in Australia. We currently operate more than 100 POPs and Internet
access nodes within our principal service regions. Here is further information
about the location and type of our switches:

</TABLE>

Our international gateway switches will serve as the base for our global
expansion of the network into new countries when customer demand justifies the
investment and as regulatory rules permit us to compete in new markets. We are
currently installing an international gateway switch in Paris, which is
expected to be operational during the third quarter of 1999. By the end of
2000, we intend to add up to 11 switches in Europe, one switch in North America
and one switch in Japan.

   Fiber Capacity. We own and lease transmission capacity which connects our
switches to each other and to the networks of other international and domestic
telecommunications carriers. Our ownership interests in fiber consist of
minimum assignable ownership units and indefeasible rights of use in 23
undersea fiber optic cable systems, including the CANTAT-3, TAT-12/TAT-13, TPC-
5, Gemini, Atlantic Crossing-1, FLAG, Americas 1 and Columbus 2 systems.

   We also have entered into an agreement to purchase $20 million of fiber
capacity from Qwest, which will provide connections among our U.S. gateway
switches and future points of presence. By replacing existing leased lines in
the U.S. with this Primus-owned high speed capacity, we expect to reduce our
cost structure and provide improved service to customers on our high traffic
routes. During the fourth quarter of 1998, we began

                                       55
<PAGE>


using the first portion of this capacity--a DS-3 link between New York and Los
Angeles. In May 1999 through a reciprocal capacity purchase agreement with
Global Crossing Holdings Ltd., we agreed to purchase up to $50 million of fiber
capacity on Global Crossing's undersea fiber network.

   Satellite Earth Stations and Capacity. We are constructing international
satellite earth stations and purchasing capacity on international satellites in
order to provide data and Internet transmission services, in addition to voice
services, principally to and from post, telephone and telegraph operators,
other telecommunications carriers and Internet service providers, in developing
countries. We have completed the construction of an Intelsat earth station in
London and have reserved capacity on the Intelsat-62(degrees) satellite. This
earth station now is operational, and is able to carry voice, data and Internet
traffic to and from countries in the Indian Ocean/Southeast Asia region,
Eastern Africa and the Middle East. Pursuant to our purchase agreement with
Global Crossing, Global Crossing has agreed to purchase up to $25 million of
services on our global satellite network. By the end of 1999, we expect to
expand our global satellite coverage by leasing a satellite earth station on
each of the east and west coasts of the United States and by reserving
additional capacity on international satellites. These additional facilities
will position us to provide voice, data and Internet transmission services to
Latin America and the Pacific Rim.

   Foreign Carrier Agreements. In selected countries where competition with the
traditional incumbent post, telephone and telegraph operators is limited or is
not currently permitted, we have entered into foreign carrier agreements with
post, telephone and telegraph operators or other service providers which permit
us to carry traffic into and receive return traffic from these countries. We
have existing foreign carrier agreements with post, telephone and telegraph
operators in Cyprus, Greece, India, Iran, Italy and New Zealand, as well as
additional carrier agreements with foreign service providers in other
countries.

Industry Overview

   General. The international long distance industry, which involves the
transmission of voice and data from one country to another, is undergoing a
period of fundamental change. The change has resulted in, and is expected to
continue to result in, significant growth in usage of international
telecommunications services. According to TeleGeography, in 1997, the
international long distance industry accounted for $66 billion in revenues and
82 billion minutes of use. That is an increase from $27 billion in revenues and
22 billion minutes of use in 1988. TeleGeography has estimated that, under one
scenario, by the year 2001 this market will have expanded to $80 billion in
revenues and 159 billion minutes of use.

   We believe that the growth in international long distance services is being
driven by:

  .  globalization of the world's economies and the worldwide trend toward
     telecommunications deregulation;

  .  the growth of data and Internet traffic;

  .  declining prices and a wider choice of products and services driven by
     greater competition resulting from privatization and deregulation;

  .  increased telephone accessibility resulting from technological advances
     and greater investment in telecommunications infrastructure, including
     deployment of wireless networks; and

  .  increased international business and leisure travel.

  We believe that growth of traffic originated in markets outside the United
States will continue to be higher than growth in traffic originated within the
United States due to recent deregulation in many foreign markets and increasing
access to telecommunications facilities in emerging markets.

   The competition spurred by privatization and deregulation, which in turn has
prompted carriers to offer a wider choice of products and services, has lowered
prices. In recent years, prices for long distance services have decreased
substantially and are expected to continue to decrease in most of the markets
in which we

                                       56
<PAGE>


currently compete. Several long distance carriers in the United States have
introduced pricing strategies that provide fixed, low rates for both domestic
and international calls originating in the United States. We believe that the
lower-price environment and resulting revenue losses from increased competition
have been more than offset by cost decreases, as well as an increase in
telecommunications usage. For example, based on the most current Federal
Communications Commission data which we believe is publicly available, for the
period 1989 through 1996, per minute settlement payments by United States-based
carriers to foreign post, telephone and telegraph operators fell 38.6%, from
$0.70 per minute to $0.43 per minute. At the same time, per minute
international billed revenue fell only 27.5%, from $1.02 in 1989 to $0.74 in
1996. We believe that, as settlement rates and costs for leased capacity
continue to decline, international long distance will continue to provide high
revenue and gross profit per minute.

   Facilities-based Carriers. International long distance carriers generally
can be categorized according to ownership and use of transmission facilities
and switches. Although no carrier utilizes exclusively owned facilities for the
transmission of all of its long distance traffic, carriers vary from being
primarily facilities-based (i.e., they own and operate their own land based or
undersea cable and switches) to those that are purely resellers of another
carrier's transmission network.

   Regulatory and Competitive Environment. Prior to deregulation, the long
distance carriers in any particular country generally were government-owned
monopoly carriers, such as British Telecom in the United Kingdom, France
Telecom in France, Deutsche Telekom in Germany, Telstra in Australia, NTT in
Japan, and Teleglobe in Canada. Deregulation of a particular telecommunications
market typically has begun with the introduction of a second long distance
carrier, followed by the governmental authorization of multiple carriers. In
the United States, one of the first highly deregulated markets, deregulation
began in the 1960's with MCI's authorization to provide long distance service
and was followed in 1984 by AT&T's divestiture of the regional Bell operating
companies and, most recently, by the passage of the 1996 Telecommunications
Act. Deregulation has occurred elsewhere, such as in the United Kingdom, Canada
and Australia, and is being implemented in other countries, including most EU
countries, Japan and several Latin American countries, such as Chile,
Guatemala, Peru, El Salvador and Mexico.

   On February 15, 1997, the United States and 68 other countries, including
Australia, the United Kingdom, Canada, Germany and Japan, signed the World
Trade Organization Agreement and agreed to open their telecommunications
markets to competition and foreign ownership starting January 1, 1998. These 69
countries generate a substantial majority of worldwide telecommunications
traffic. We believe that the World Trade Organization Agreement has begun to,
and will continue to, provide us with significant opportunities to compete in
markets where we did not previously have access and will allow us to provide
end-to-end, facilities-based services to and from these countries.

   In addition, to implement the United States' "open market" commitments under
the World Trade Organization Agreement, the FCC has (i) eliminated the FCC's
Effective Competitive Opportunities test for applicants affiliated with
carriers in World Trade Organization member countries, while imposing new
conditions on participation by dominant foreign carriers, (ii) allowed
nondominant United States carriers to enter into exclusive arrangements with
nondominant foreign carriers and scaled back the prohibition on exclusive
arrangements with dominant carriers and (iii) adopted rules that will
facilitate approval of flexible alternative settlement payment arrangements. We
believe that the FCC order has had and will continue to have the following
effects on United States carriers:

  .  reduce impediments to investment in United States carriers by foreign
     entities,

  .  increase opportunities to enter into innovative traffic arrangements
     with foreign carriers located in World Trade Organization member
     countries,

  .  add new opportunities to engage in international simple resale to
     additional foreign countries and

  .  modify settlement rates offered by foreign affiliates of United States
     carriers to United States carriers to comply with the FCC's settlement
     rate benchmarks.

   International Traffic Dynamics. A long distance telephone call consists of
three parts: origination, transport and termination. Generally, a domestic long
distance call originates on a local exchange network and is transported to the
network of a long distance carrier, which in many countries is the same as the
local carrier. The call is then carried along the long distance network to
another local exchange network where the call is terminated. An international
long distance call is similar to a domestic long distance call, but typically
involves at least two long distance carriers with the first carrier
transporting the call from the country of origination, and the second carrier
terminating the call in the country of termination. These long distance
telephone calls are classified as one of three types of traffic: outbound,
inbound and international transit. Outbound traffic consists of calls going
from a country of origination, and inbound traffic consists of calls going into
a country of destination. For example, a call made from the United States to
the United Kingdom is referred to as outbound traffic for the United States
carrier and inbound traffic for the United Kingdom carrier. The third type of
traffic, international transit traffic, originates and terminates outside a
particular country, but is transported through that country on a carrier's
network. Since most major international fiber optic cable systems are connected
to the United States, and international long distance prices are substantially
lower in the United States than in other countries, a large volume of
international transit traffic is routed through the United States.

   International calls are transported by land based or undersea cable or via
satellites. A carrier can obtain voice circuits on cable systems either through
ownership or leases. Ownership in cables is acquired either through
indefeasible rights of use or minimum assignable ownership units. The
fundamental difference between a holder of indefeasible rights of use and an
owner of minimum assignable ownership units is that the indefeasible rights of
use holder is not entitled to participate in management decisions relating to
the cable system. Between two countries, a carrier from each country owns a
"half-circuit" of a cable, essentially dividing the ownership of the cable into
two equal components. Additionally, any carrier may generally lease circuits on
a cable from another carrier. Unless a carrier owns a satellite, satellite
circuits also must be leased from one of several existing satellite systems.

   Accounting Rate Mechanism. Under the accounting rate mechanism, which is the
traditional model for handling long distance traffic between international
carriers, traffic is exchanged under bilateral carrier agreements, or operating
agreements, between carriers in two countries. Foreign carrier agreements
generally are three to five years in length and provide for the termination of
traffic in, and return traffic to, the carriers' respective countries at a
negotiated accounting rate, known as the total accounting rate. In addition,
foreign carrier agreements provide for network coordination and accounting and
settlement procedures between the carriers. Both carriers are responsible for
costs and expenses related to operating their respective halves of the end-to-
end international connection.

   Settlement costs, which typically equal one-half of the total accounting
rate, are the fees owed to another international carrier for transporting
traffic on its facilities. Settlement costs are reciprocal between each party
to a foreign carrier agreement at a negotiated rate (which must be the same for
all United States-based carriers, unless the FCC approves an exception). For
example, if a foreign carrier charges a United States carrier $0.30 per minute
to terminate a call in the foreign country, the United States carrier would
charge the foreign carrier the same $0.30 per minute to terminate a call in the
United States. Additionally, the total accounting rate is the same for all
carriers transporting traffic into a particular country, but varies from
country to country. The term "settlement costs" arises because carriers
essentially pay each other on a net basis determined by the difference between
inbound and outbound traffic between them.

   Foreign carrier agreements typically provide that a carrier will return
terminating traffic in proportion to the traffic it receives. Return traffic
generally is more profitable than outgoing traffic because the settlement rate
per minute is substantially greater than the incremental cost of terminating a
call in the country due to the lack of marketing expense and billing costs, as
well as the lower cost structure associated with terminating calls within
country. Generally, there is a six-month lag between outbound traffic and the
allocation of the corresponding return traffic and, in certain instances, a
minimum volume commitment must be achieved before qualifying for receipt of
return traffic.

<PAGE>

   Alternative Calling Procedures. As the international long distance market is
being deregulated, long distance companies have devised alternative calling
procedures in order to complete calls more economically than under the
accounting rate mechanism. Some of the more significant alternative calling
procedures include:

  .  transit,

  .  refiling or "hubbing,"

  .  international simple resale and

  .  reorigination.

   The most common of the above methods is transit. The transit procedure
allows traffic between two countries to be carried through a third country on
another carrier's network. This procedure, which requires agreement among the
particular long distance companies and the countries involved, generally is
used either for overflow traffic during peak periods or where the direct
circuit may not be available or justified based on traffic volume. Refiling or
"hubbing" of traffic, which takes advantage of disparities in settlement rates
between different countries, allows traffic to a particular country to be
treated as if it originated in another country that enjoys lower settlement
rates with the destination country, thereby resulting in lower overall costs on
an end-to-end basis. United States-based carriers generally are beneficiaries
of refiling on behalf of other carriers because of low international rates. The
difference between transit and refiling is that, with respect to transit, the
carrier in the destination country has a direct relationship with the
originating carrier, while with refiling, the carrier in the destination
country is likely not to even know the identity of the originating carrier. The
choice between transit and refiling is determined primarily by cost. With
international simple resale, a carrier may completely bypass the settlement
system by connecting an international leased or owned line directly to the
public-switched telephone network of a foreign country or directly to a
customer premise through an international gateway switch deployed in the
foreign country. International simple resale currently is allowed by applicable
regulatory authorities between a limited number of international routes,
including Canada-United Kingdom, United States-United Kingdom, United States-
Sweden and United Kingdom-Australia and is currently experiencing increasing
usage. Reorigination avoids the high international rates in a particular
country of origin by providing dial tone in a second country with a lower rate,
typically the United States.

   Industry Strategies. Strategies to provide international long distance
services are driven by the emergence of alternative calling procedures and the
increased demand for seamless services on a global basis. First-tier service
providers, which largely utilize their own network facilities, primarily
utilize foreign carrier agreements in order to provide international service.
Second-tier carrier and new entrants which, to a greater extent must rely on
the network facilities of other carriers, primarily are utilizing alternative
calling procedures and are developing networks to compete with the first-tier
carriers and gain market share. Other entrants, including Primus, are
establishing their own operations in multiple countries and, to the extent
required to serve other selected markets, alliances or other arrangements with
other carriers. In response, first-tier carriers have formed alliances to
provide seamless services and one-stop shopping on a global basis.

Strategy

   Our objective is to become a leading global provider of international and
domestic long distance voice, Internet, data and other services in our
principal service regions. Key elements of our strategy to achieve this
objective include:

  .  Focus on Customers with Significant International Long Distance
     Usage. We primarily target customers with significant international long
     distance usage, including small- and medium-sized businesses,
     multinational corporations, ethnic residential customers and other
     telecommunication carriers and resellers. We believe that the
     international long distance market offers an attractive business
     opportunity given its size and, as compared to the domestic long
     distance market, its higher revenue per minute, gross margin and
     expected growth rate.

  .  Pursue Early Entry into Selected Deregulating Markets. We seek to be an
     early entrant into selected deregulating telecommunications markets
     where we believe there is significant demand for international long
     distance services as well as substantial growth and profit potential. We
     further believe that early entrance into deregulating markets provides
     us with competitive advantages as we develop sales channels, establish a
     customer base, hire personnel experienced in the telecommunications
     industry and achieve name recognition, prior to the entry into these
     markets by a large number of competitors. We intend to continue to
     concentrate our immediate expansion plans in those markets that are more
     economically stable and are experiencing more rapid deregulation, such
     as continental Europe and Canada. Subsequently, we expect to expand in
     additional markets within our principal service regions, including
     Japan, other parts of the Asia-Pacific region and Latin America.

  .  Expand Our Global Network. By constructing and expanding our network, we
     have reduced operating costs, improved service reliability and increased
     our flexibility to introduce new services. We expect that continued
     strategic development of our network will continue to lead to reduced
     transmission and other operating costs as a percentage of net revenue,
     improved gross margins, reduced reliance on other carriers and more
     efficient network utilization. We own our own switching facilities,
     fiber optic cable capacity and a satellite earth station and purchase
     fiber optic cable capacity on an end-to-end basis and satellite
     transmission capacity when we believe that current and expected traffic
     levels justify such investment. We also expect to expand our network
     capacity and offer voice, data and Internet services, all based on Cisco
     Internet Protocol technology, enabling us to be selected as a Cisco
     powered network.

  .  Provide Full Portfolio of Voice, Data and Internet Services. We
     typically enter markets which are in the initial stages of deregulation
     by first providing international long-distance services and, as the
     market deregulates further, by expanding our portfolio of service
     offerings within the particular market. We believe that international
     long distance generally offers attractive margins in markets in the
     early stage of deregulation and provides a platform for expanding our
     service offerings to our customers. In an effort to attract larger
     business customers in multiple markets, we intend to offer a broad array
     of services (including long distance voice, Internet, data and cellular
     services) in approximately 10 major markets, including the United
     States, Canada, Australia, the United Kingdom, Germany, France, Japan
     and Italy. In May 1999, we formed a new Internet and data subsidiary,
     iPRIMUS.com, and anticipate offering a full range of Internet Protocol-
     based data and voice communication over our existing global network
     infrastructure.

  .  Provide Transmission for Internet and Data Services in Developing
     Countries. We plan to offer satellite-based broadband transmission
     capacity to post, telephone and telegraph operators, other
     telecommunications carriers, ISPs and multi-national corporations
     principally serving developing countries. We focus these services on
     developing countries due to their limited capacity to handle their
     rapidly-growing Internet and data traffic. Our satellite earth station
     in London enables us to offer Internet and data transmission services in
     the Indian Ocean/Southeast Asia region. Additionally, we plan to
     replicate this strategy so as to offer such services in Latin America
     and the Pacific Rim by adding two additional satellite earth stations,
     one on each of the east and west coasts of the United States.

  .  Broaden Retail Customer Base. By offering high quality services at
     competitive prices, providing high levels of customer service, and
     bundling a comprehensive selection of voice, cellular, data, Internet,
     cellular and other value added services, we intend to further broaden
     our retail customer base. In order to offer our retail customers
     international and domestic long distance services generally priced below
     those of major carriers in our principal service regions, we intend to
     maintain a low cost structure. In order to maintain high levels of
     customer service, we intend to continue to use trained and experienced
     sales and service representatives and to provide customized billing
     services. By bundling our traditional voice services with data and
     Internet services, we intend not only to attract more retail customers
     but also to reduce per customer sales and marketing costs and customer
     turnover.


                                       60

  .  Growth through Selected Acquisitions, Joint Ventures and Strategic
     Investments. As part of our business strategy, we frequently evaluate
     potential acquisitions, joint ventures and strategic investments. We
     view acquisitions, joint ventures and strategic investments as means to
     enter additional markets, add new products and market segments (for
     example, data and Internet), expand our operations within existing
     markets and increase our customer and revenue base, thereby facilitating
     an acceleration of our business plan. Potential candidates include voice
     and data service providers and ISPs with an established customer base,
     complementary operations, telecommunications licenses, experienced
     management or network facilities in countries into which we seek to
     enter.

Description of Operating Markets

   The following is a summary of the market size, competitive dynamics and
regulatory environments of the domestic and international long distance
industries in the principal jurisdictions in which we provide our services and
a description of our operations in each of our primary service regions:

   North America. The United States long distance market is highly deregulated
and is the largest in the world. According to the FCC, in 1996 long distance
telephone revenue in the United States was approximately $99.7 billion,
including approximately $17.9 billion from international services (representing
18.0% of the total market). AT&T is the largest long distance carrier in the
United States market, with market share of approximately 49.9% of international
outgoing minutes in 1996. MCI/WorldCom and Sprint had market shares of 28.1%
and 14.4%, respectively in 1996. AT&T, MCI/WorldCom and Sprint constitute what
generally is regarded as the first-tier in the United States long distance
market. Other large long distance companies with more limited ownership of
transmission capacity, such as Frontier and Qwest, constitute the second-tier
of the industry. The remainder of the United States long distance market is
comprised of several hundred smaller companies, largely resellers, which are
known as third-tier carriers.

   In the United States, we provide long distance services to small- and
medium-sized businesses, residential customers, multinational corporations and
other telecommunication carriers. We operate international gateway telephone
switches in the New York City area, Washington, Fort Lauderdale and Los Angeles
which are connected with countries in Europe, Latin America and the Asia-
Pacific region through owned and leased international fiber cable systems. We
maintain a direct sales organization in New York and Virginia to sell to
business customers and have a telemarketing center for small business sales in
Tampa. To reach residential customers, we advertise nationally in ethnic
newspapers and other publications, offering discounted rates for international
calls to targeted countries. We also utilize independent agents to reach and
enhance sales to both business and residential customers and have established a
direct sales force for marketing international services to other long distance
carriers. Additionally, as a result of the TresCom merger, we have expanded our
marketing activities to customers in the United States seeking to transmit
international calls to Latin America, consisting principally of businesses with
sales or operations in Latin America, as well as the growing Hispanic
population in the United States. We maintain a national customer service center
in Florida staffed with multi-lingual representatives and operate a 24-hour
global network management control center in Virginia that monitors our network.
We also operate network management control centers in London, Sydney and,
following the Telegroup acquisition, in Cedar Rapids, Iowa. In addition to
international long distance services, we provide local service in Puerto Rico
and the United States Virgin Islands.

   According to the International Telecommunications Union, the total
telecommunications market in Canada accounted for approximately $13.2 billion
in revenues in 1996. In Canada, Stentor, a partnership of Canadian regional
telephone companies, was the largest provider of long distance services prior
to 1999. The Stentor partnership was discontinued on January 1, 1999, and the
former Stentor partner companies such as Bell Canada and BCT.Telus
Communications now compete against one another for the first time. Two other
types of long distance providers also compete against the former Stentor
partner companies. The first, which includes AT&T Canada and Call-Net
Enterprises (Sprint Canada), owns and operates interexchange circuits and
offers essentially the same services as the former Stentor partner companies.
The second type of competitor consists of other long distance providers that
lease but do not own interexchange circuits and sell their services primarily
to distinct niche markets, such as ethnic communities, affinity associations or
small business

                                       61

associations. In Canada, we provide long distance services to small- and
medium-sized businesses, residential customers and other telecommunication
carriers and have sales and customer service offices in Vancouver, Toronto and
Montreal. We operate international gateway switches in Toronto and Vancouver,
maintain points-of-presence in Ottawa, Montreal and Calgary and lease
interexchange circuits in Canada. In Canada, we offer Internet access services
through our February 1999 acquisition of GlobalServe Communications, Inc. In
March 1999, we acquired London Telecom Network, Inc. and certain related
entities which provide long distance telecommunications services in Canada.
With this acquisition and the completion of the acquisition of the related
Wintel companies, we believe we are the third largest long distance provider in
Canada among competitors to the former Stentor partner companies based on
revenues. In June 1999, we acquired Telephone Savings Network Ltd., a reseller
of local services to small- and medium-sized business customers in Canada.

   According to the International Telecommunications Union, the total
telecommunications market in Mexico accounted for approximately $6.9 billion in
1996. As of January 1, 1997, the local and long distance market was opened to
facilities-based competition in Mexico. Mexico, however, imposes foreign
ownership restrictions that limit the ownership of facilities-based carriers by
non-Mexican persons to below 50%. The Mexican government has granted licenses
to 10 companies (many of them affiliated with U.S.-based long distance carriers
such as AT&T and MCI/WorldCom) to operate as facilities-based long distance
carriers. Resale of basic switched voice long distance services, however, is
still not allowed in Mexico. We provide customers with United States-Mexico
cross border private line services, but are prohibited by the private ownership
limitations from providing other services.

   As of June 30, 1999, we had approximately 385,000 business customers and
875,000 residential customers in North America.

   Asia-Pacific. According to the International Telecommunications Union, in
1996, the total telecommunications market in Australia accounted for
approximately $13.4 billion in revenues. Telstra and Cable & Wireless Optus,
the leading full-service carriers in Australia, own and operate local, national
and international transmission networks. Telstra, which is majority-owned by
the Australian government, is a traditional facilities-based carrier with a
majority of the telecommunications market share. In addition to Cable &
Wireless Optus and us, Telstra currently competes against other facilities-
based carriers (such as AAPT), several switchless resellers and call-back
service providers (including CorpTel), and mobile telecommunications carriers
(such as Vodafone). Australia has further deregulated its long-distance market
by allowing service providers other than Telstra and Cable & Wireless Optus to
own domestic transmission facilities and mandating that Telstra provide equal
(non-code) access to customers of select service providers such as us. We are a
licensed carrier permitted to own and operate transmission facilities in
Australia.

   We are the fourth largest long distance company in Australia based on
revenues, providing domestic and international long distance services, data and
Internet access services, as well as local and cellular service on a resale
basis, to small- and medium-sized business customers and ethnic residential
customers. We have invested substantial resources over the past three years to
build a domestic and international long distance network to transform our
Australian operations into a facilities-based telecommunications carrier.
During 1997, we installed and began operating a five-city switched network
using Northern Telecom switches in Sydney, Melbourne, Perth, Adelaide, and
Brisbane. We purchased international fiber cable capacity during 1997 and
linked the Australian network to the United States via the TPC-5, APCN, and
Jasaurus cable systems, as well as to New Zealand. We became a fully licensed
facilities-based telecommunications carrier on July 1, 1997. In August 1997,
equal access was introduced in Australia, and we began the process of migrating
and connecting customers directly onto our own network. We maintain both a 24-
hour customer service center and a network management control center in
Australia.

   In March 1998, we purchased a controlling interest in Hotkey, an Australia-
based ISP, and in April 1998, we acquired all of the outstanding stock of
Eclipse, an Australia-based data communications service provider. In February
1999, we purchased the remaining stock in Hotkey. The Hotkey and Eclipse
acquisitions positioned us to offer a complete range of telecommunications
services for corporate customers in Australia,

                                       62
<PAGE>

including fully integrated voice and data networks, as well as Internet access.
We market our services through a combination of direct sales to small- and
medium-sized business customers, independent agents which market to business
and residential customers, and media advertising aimed at ethnic residential
customers living in Australia who make a high volume of international calls.

   We entered the Japanese market in late 1997 through the TelePassport/USFI
acquisition. According to the International Telecommunications Union, in 1997,
the total telecommunications market in Japan accounted for approximately $86.5
billion in revenues. We maintain an office in downtown Tokyo and operate an
international gateway switch to provide international calling services to
resellers and small businesses. We interconnected our Tokyo switch to Los
Angeles via the TPC-5 fiber cable system. We have a Type I carrier license,
which permits us to provide selected telecommunications services using our own
facilities in Japan. We plan to market our services in Japan through direct
sales and relationships that we are establishing with business partners.

   As of June 30, 1999, we had approximately 29,250 business customers and
294,110 residential customers in the Asia-Pacific region.

   Europe. According to the International Telecommunications Union, in 1997 the
total telecommunications market in the United Kingdom accounted for
approximately $32.4 billion in revenue. In the United Kingdom, British Telecom
historically has dominated the telecommunications market and is the largest
carrier. Mercury, which owns and operates interexchange transmission
facilities, is the second largest carrier. The remainder of the United Kingdom
long distance market is comprised of an emerging market of licensed
telecommunications service providers, such as Energis, and switch-based
resellers, such as AT&T, MCI/WorldCom, ACC and GTS/Esprit.

   We are a fully-licensed carrier in the United Kingdom and provide domestic
and international long distance services to residential customers, small
businesses, and other telecommunications carriers. We operate an Ericsson AXE-
10 international gateway telephone switch in London, which is directly
connected to the United States and is directly connected to continental Europe
via our international gateway switch in Frankfurt, Germany. In addition, we
have completed the construction in London of an Intelsat earth station and
lease capacity on the Intelsat-62(degrees) satellite. This new earth station is
operational and is able to carry voice, data and Internet traffic to and from
countries in the Indian Ocean/Southeast Asia region. Our European operations
are headquartered in London, where we maintain both a 24-hour customer service
call center and a 24-hour network management control center which monitors our
network in the United Kingdom. We market our services in the United Kingdom
using a combination of direct sales, agents, and direct media advertising
primarily to ethnic customers who make a higher-than-average percentage of
international calls.

   We are in the process of expanding our services and network to continental
Europe which has recently begun the process of deregulation of its
telecommunications markets. We currently hold a Class-4 switched voice
telephone license in Germany, an L34.1 switched voice license in France and a
voice services license in Switzerland. According to the International
Telecommunications Union, in 1997, the German telecommunications market
generated approximately $46.1 billion in revenues and the French
telecommunications market generated approximately $26.9 billion in revenues.
Our international gateway switch in Paris recently became operational, and by
the end of the second quarter of 2000, our network in Europe is expected to
include the Frankfurt international gateway switch which is currently
operational, and up to 11 additional switches in various countries. Through the
TelePassport/USFI acquisition, we acquired a base of small business customers
in Germany to whom we provide reorigination services, establishing a platform
for our expansion into that market. Additionally, we have opened our first
continental European sales office in Frankfurt and are in the process of
building a direct sales force and engaging independent sales agents to market
our services.

   As of June 30, 1999, we had approximately 1,020 business customers and
43,900 residential customers in the United Kingdom.

Services

   We offer a broad array of telecommunications services through our network
and through interconnection with the networks of other carriers. Our decision
to offer certain services in a market is based on competitive factors and
regulatory restraints within the market. Below is a summary of services we
offer:

  .  International and Domestic Long Distance. We provide international long
     distance voice services terminating in approximately 230 countries, and
     provide domestic long distance voice services within selected countries
     within our principal service regions. Access methods required to
     originate a call vary according to regulatory requirements and the
     existing domestic telecommunications infrastructure.

  .  Private Network Services. For business customers, we design and
     implement international private network services that may be used for
     voice, data and video applications.

  .  Reorigination Services. In selected countries, we provide call
     reorigination services which allow non-United States country to country
     calling to originate from the United States, thereby taking advantage of
     lower United States accounting rates.

  .  Local Switched Services. We intend to provide local service on a resale
     basis as part of our "multi-service" marketing approach, subject to
     commercial feasibility and regulatory limitations. We currently provide
     local service in Australia, Puerto Rico and the United States Virgin
     Islands.

  .  Toll-free Services. We offer domestic and international toll-free
     services within selected countries within our principal service regions.

  .  Data and Internet Services. In Australia, we offer data services over
     asynchronous transfer mode (ATM) and frame relay networks in addition to
     other data services including Internet access. In Canada, we offer
     Internet access services through our February 1999 acquisition of
     GlobalServe and our May 1999 acquisition of ACC Telenterprises. In
     Germany, we offer Internet access services through our May 1999
     acquisition of TCP/IP. Our satellite earth station in London enables us
     to offer Internet and data transmission services in the Indian
     Ocean/Southeast Asian region. We plan to replicate this strategy so as
     to offer such services in Latin America and the Pacific Rim by adding
     two additional satellite earth stations, one on each of the east and
     west coasts of the United States.

  .  Cellular Services. We resell Telstra analog and digital cellular
     services in Australia.

  .  Prepaid and Calling Cards. We offer prepaid and calling cards that may
     be used by customers for domestic and international telephone calls both
     within and outside of their home country.

Network

   General. Since our inception in 1994, we have been deploying a global
intelligent telecommunications network consisting of international and domestic
switches, related peripheral equipment, undersea fiber optic cable systems and
leased satellite and cable capacity. We believe that our network allows us to
control both the quality and cost of the on-net telecommunications services we
provide to our customers. To ensure high-quality telecommunications services,
our network employs digital switching and fiber optic technologies, uses SS7
signaling and is supported by comprehensive monitoring and technical services.
Our network consists of:

  .  a global backbone network connecting intelligent gateway switches in our
     principal service regions;

  .  a domestic long distance network presence within certain countries
     within our principal service regions; and

  .  a combination of owned and leased transmission facilities, resale
     arrangements and foreign carrier agreements.

                                       64
<PAGE>

   Each of our international gateway switches is connected to our domestic and
international networks as well as those of other carriers in a particular
market, allowing us to:

  .  provide seamless service;

  .  package and market the voice and data services purchased from other
     carriers under the "Primus" brand name; and

  .  maintain a substantial portion of each market's United States-bound
     return traffic through our integrated communications network to maintain
     quality service and cost efficiencies and increase gross margins.

   We have targeted North America, the United Kingdom and continental Europe
for the immediate development of our network due to their economic stability
and the more rapid pace of deregulation as compared to other areas of the
world. We expect to expand our network into additional markets within our
principal service regions, including in Japan and other parts of the Asia-
Pacific region and Latin America. We are using our United Kingdom operations to
coordinate efforts to enter other major markets in Europe in conjunction with
the deregulation of the telecommunications industry in certain EU countries
which began in 1998. This expansion commenced with our installation of an
international gateway switch in Frankfurt, and is continuing with our
international gateway switch in Paris, which has recently become operational,
and with our acquisition of an international gateway switch in London from a
European subsidiary of Telegroup.

   International Gateway and Domestic Switches. Our network consists of 19
carrier-grade switches, including 15 international gateway switches (three in
the New York City area, two in London and one in each of Los Angeles,
Washington, Fort Lauderdale, Toronto, Vancouver, London, Paris, Frankfurt,
Sydney, Tokyo and Puerto Rico), and four domestic switches in Australia
(Adelaide, Brisbane, Melbourne and Perth). We currently operate more than 100
POPs and Internet access nodes within our principal service regions. All of our
switches were manufactured by Nortel or Ericsson, except for the Washington and
Canadian switches.

                                       65
<PAGE>

   Fiber Optic Cable Systems. Where our customer base has developed sufficient
traffic, we have purchased and leased undersea and land-based fiber optic cable
transmission capacity to connect to our various switches. Where traffic is
light or moderate, we obtain capacity to transmit traffic on a per-minute
variable cost basis. When traffic volume increases and such commitments are
cost effective, we either purchase lines or lease lines on a monthly or longer
term basis at a fixed cost and acquire economic interests in transmission
capacity through minimum assignable ownership units and indefeasible rights of
use to international traffic destinations. The following chart sets forth a
listing of the undersea fiber optic cable systems in which we have capacity
(which includes both minimum assignable ownership units and indefeasible rights
of use):

   We have also entered into an agreement to purchase $20 million of fiber
capacity from Qwest, which will provide connections among our U.S. gateway
switches and future points of presence. By replacing existing leased lines in
the U.S. with this Primus-owned high speed capacity, we expect to reduce our
cost structure and provide improved service to customers on our high traffic
routes. During the fourth quarter of 1998, we began using the first portion of
this capacity--a DS-3 link between New York and Los Angeles. In May, 1999

                                       66

through a reciprocal capacity purchase agreement with Global Crossing Holdings
Ltd., we agreed to purchase up to $50 million of fiber capacity on Global
Crossing's undersea fiber network.

   Satellite Earth Stations and Capacity. We are constructing international
satellite earth stations and purchasing capacity on international satellites in
order to provide data and Internet transmission services, in addition to voice
services, principally to and from post, telephone and telegraph operators,
other telecommunications carriers and Internet service providers, in developing
countries. We have completed the construction in London of an Intelsat earth
station and lease capacity on the Intelsat-62(degrees) satellite. This earth
station is now operational and is able to carry voice, data and Internet
traffic to and from countries in the Indian Ocean/Southeast Asia region,
Eastern Africa and the Middle East. Pursuant to our purchase agreement with
Global Crossing, Global Crossing has agreed to purchase up to $25 million of
capacity on our global satellite network.

   Foreign Carrier Agreements. In selected countries where competition with the
traditional incumbent post, telephone and telegraph operators is limited or is
not currently permitted, we have entered into foreign carrier agreements with
post, telephone and telegraph and other licensed operators or other service
providers which permit us to provide traffic into and receive return traffic
from these countries. We have existing foreign carrier agreements with post,
telephone and telegraph operators in Cyprus, Greece, India, Iran, Italy, New
Zealand, the Philippines, Belgium, Denmark, Israel, Ireland, Singapore,
Malaysia, Japan, Australia, France, Switzerland, Argentina, the Bahamas and the
Dominican Republic and maintain additional agreements with other foreign
carriers in other countries.

   Network Management and Control. We own and operate network management
control centers in McLean, Virginia, London and Sydney and, with the Telegroup
acquisition, in Cedar Rapids, Iowa, which are used to monitor and control a
majority of the switches and other transmission equipment used in our network.
These network management control centers operate seven days a week, 24 hours
per day, 365 days a year. In Canada, Tokyo and Frankfurt, we currently monitor
and control each switch locally. We are using a portion of the net proceeds of
the offering of the notes to be exchanged to upgrade the existing network
management control centers so that they can monitor all of our switching and
other transmission equipment throughout the entire network.

   Planned Expansion of Network. We recently installed and commenced operating
an international gateway switch in Paris. By the end of 2000, we intend to add
up to 11 additional switches in Europe, one switch in North America and one
switch in Japan. Additionally, we intend to continue to invest in additional
switches and points of presence in major metropolitan areas of our principal
service regions as the traffic usage warrants the expenditure. We also intend
to acquire capacity in terrestrial and undersea fiber optic cable systems in
our principal service regions, particularly in North America and Europe, by the
end of 1999.

Customers

   As of June 30, 1999, Primus had approximately 1.7 million customers. Set
forth below is a description of our customer base:

  .  Businesses. Historically, our business sales and marketing efforts
     targeted small- and medium-sized businesses with significant
     international long distance traffic. More recently, we have also
     targeted larger multi-national businesses. In an effort to attract these
     larger business customers in multiple markets, we intend to offer a
     broad array of services (including long distance voice, Internet, data
     and cellular services) in approximately 10 major markets, including the
     United States, Canada, Australia, the United Kingdom, Germany, France,
     Japan and Italy. We believe that these businesses are and will continue
     to be attracted to us primarily due to price savings compared to
     traditional carriers and, secondarily, due to our personalized approach
     to customer service and support, including customized billing and
     bundled service offerings.


                                       67
<PAGE>


  .  Residential Customers. Our residential sales and marketing strategy
     targets ethnic residential customers who generate high international
     traffic volumes. We believe that such customers are attracted to us
     because of price savings as compared to traditional carriers, simplified
     pricing structure, and multilingual customer service and support.

  .  Telecommunications Carriers and Resellers. We compete for the business
     of other telecommunications carriers and resellers primarily on the
     basis of price and service quality. Sales to other carriers and
     resellers help us maximize the utilization of our network and thereby
     reduce our fixed costs per minute of use.

  .  Customer Service. We strive to provide personalized customer service and
     believe that the quality of our customer service is one of our
     competitive advantages. Our larger customers are actively covered by
     dedicated account and service representatives who seek to identify,
     prevent and solve problems. We provide toll-free, 24-hour a day customer
     service in the United States, Canada, the United Kingdom and Australia
     which can be accessed to complete collect, third party, person-to-
     person, station-to-station and credit card validation calls. We also
     provide a multi-lingual "Trouble Reporting Center" for our residential
     customers. As of June 30, 1999, we employed approximately 466 full-time
     customer service employees, many of whom are multi-lingual.

Sales and Marketing

   We market our services through a variety of sales channels, as summarized
below:

  .  Direct Sales Force. As of June 30, 1999, our direct sales force was
     comprised of 282 full-time employees who focus on business customers
     with substantial international traffic, including multinational
     businesses and international governmental organizations. As of June 30,
     1999, we employed 213 full-time direct sales representatives focused on
     ethnic residential consumers and direct sales representatives who
     exclusively sell wholesale services to other long-distance carriers and
     resellers. Direct sales personnel are compensated with a base salary
     plus commissions. We currently have offices in New York City, Virginia,
     Tampa, Puerto Rico, St. Thomas, Montreal, Toronto, Vancouver, Mexico
     City, London, Frankfurt, Adelaide, Brisbane, Melbourne, Perth, Sydney
     and Tokyo.

  .  Independent Sales Agents. We also sell our services through independent
     sales agents and representatives, who typically focus on residential
     consumers and small- and medium-sized businesses. In June 1999, we
     significantly expanded our independent sales agent program through the
     acquisition of Telegroup's global network of agents and its agent
     support systems. These support systems include RepLink, a World Wide Web
     interface that allows agents to send customer information directly to us
     via the Internet for fully automated provisioning. Through RepLink,
     agents also receive monthly usage reports, commission reports, reports
     on new products and updates about the agent program.

       An agent receives commissions based on revenue generated by
    customers obtained for us by the agent. We also provide additional
    incentives in the form of restricted stock to those agents that meet
    certain revenue growth targets. We usually grant only nonexclusive
    sales rights and require our agents and representatives to maintain
    minimum revenues. we also market our services through representatives
    of network marketing companies.

  .  Telemarketing. We employ full-time telemarketing sales personnel in our
     Tampa call center to supplement sales efforts to ethnic residential
     consumers and small- and medium-sized business customers.

  .  Media and Direct Mail. We use a variety of print, television and radio
     advertising to increase name recognition and generate new customers. We
     reach ethnic residential consumers by print advertising campaigns in
     ethnic newspapers, and by advertising on select radio and television
     programs.

Management Information and Billing Systems

   We use various management information, network and customer billing systems
in our different operating subsidiaries to support the functions of network and
traffic management, customer service and customer billing. For financial
reporting, we utilize a common system in each of our markets. For our billing
requirements in the United States, we use a customer billing system developed
by Electronic Data Systems Inc. (EDS) which supplies, operates and maintains
this system and is responsible for providing backup facilities and disaster
recovery. The EDS system is widely used in the telecommunications industry and
has been customized to meet our specific needs. Elsewhere, we use other third
party systems or systems developed in-house to handle our billing requirements.
We bill all of our business, reseller and residential customers directly in all
of our principal service regions.

   We believe that, subject to modifications which are necessary to make our
systems Year 2000 compliant, our financial reporting and billing systems are
generally adequate to meet our needs in the near term. However, as we continue
to grow, we will need to invest additional capital to purchase hardware and
software, license more specialized software, increase capacity and link our
systems among different countries.

Competition

   The international telecommunications industry is highly competitive and
significantly affected by regulatory changes, marketing and pricing decisions
of the larger industry participants and the introduction of new services made
possible by technological advances. We believe that long distance service
providers compete on the basis of price, customer service, product quality and
breadth of services offered. In each country of operation, we have numerous
competitors. We believe that as the international telecommunications markets
continue to deregulate, competition in these markets will increase, similar to
the competitive environment that has developed in the United States following
the AT&T divestiture in 1984. Prices for long-distance voice calls in the
markets in which we compete have declined historically and are likely to
continue to decrease. In addition, many of our competitors are significantly
larger, have substantially greater financial, technical and marketing resources
and larger networks.

   Privatization and deregulation have had, and are expected to continue to
have, significant effects on competition in the industry. For example, as a
result of legislation enacted in the United States, regional Bell operating
companies will be allowed to enter the long distance market, AT&T, MCI/WorldCom
and other long distance carriers will be allowed to enter the local telephone
services market, and cable television companies and utilities will be allowed
to enter both the local and long distance telecommunications markets. In
addition, competition has begun to increase in the European Union
telecommunications markets in connection with the deregulation of the
telecommunications industry in most EU countries, which began in January 1998.
This increase in competition could adversely affect net revenue per minute and
gross margin as a percentage of net revenue.

   The following is a brief summary of the competitive environment in selected
countries within each of its principal service regions:

  .  North America. In the United States, which is the most competitive and
     among the most deregulated long distance markets in the world,
     competition primarily is based upon pricing, customer service, network
     quality, and the ability to provide value-added services. AT&T is the
     largest supplier of long distance services, with MCI/WorldCom and Sprint
     being the next largest providers. In the future, under provisions of
     recently enacted federal legislation, we anticipate that we will also
     compete with regional Bell operating companies, local exchange carriers
     and ISPs in providing domestic and international long-distance services.
     The Canadian telecommunications market is highly competitive and is
     dominated by a few established carriers whose marketing and pricing
     decisions have a significant impact on the other industry participants
     including us. We compete with facilities-based carriers, other resellers
     and rebillers, primarily on the basis of price. The principal
     facilities-based competitors include the former Stentor member
     companies, in particular, Bell Canada, the

                                       69
<PAGE>


     dominant supplier of local and long-distance services in Canada, and
     BCT.Telus Communications, the next largest Stentor company, as well as
     non-Stentor companies, AT&T Canada Corp., Teleglobe Canada and Call-Net
     Enterprises (Sprint Canada). Based upon current market share estimates,
     the former Stentor member companies control approximately 70.0% of the
     entire Canadian long distance market and approximately 66.0% of the
     business long distance market. The former Stentor member companies
     discontinued their alliance on January 1, 1999 and now compete against
     one another for the first time.

  .  Asia-Pacific. Australia is one of the most deregulated and competitive
     telecommunications markets in the Asia-Pacific region. Our principal
     competitors in Australia are Telstra, the dominant carrier, Cable &
     Wireless Optus and AAPT and a number of other switchless resellers. We
     compete in Australia by offering a comprehensive menu of competitively-
     priced products and services, including value-added services, and by
     providing superior customer service and support. We believe that
     competition in Australia will increase as more companies are awarded
     carrier licenses in the future. Our principal competitor in Japan is
     KDD, the dominant carrier, as well as Japan Telecom, IDC and a number of
     second tier carriers, including Cable & Wireless, MCI/WorldCom and
     ATNet.

  .  Europe. Our principal competitors in the United Kingdom are British
     Telecom, the dominant supplier of telecommunications services in the
     United Kingdom, and Cable & Wireless Communications. Other competitors
     in the United Kingdom include Colt, Energis, GTS/Esprit and RSL
     Communications. We compete in the United Kingdom and continental Europe,
     and expect to compete in other European countries, by offering
     competitively-priced bundled and stand-alone services, personalized
     customer service and value-added services. Our principal competitor in
     Germany is Deutsche Telekom, the dominant carrier. We also compete with
     Mannesmann ARCOR/O.tel.o Communications, VIAG Interkom, MobilCom,
     Talkline, NTS/Colt, MCI/WorldCom and RSL Communications. Additionally,
     we also face competition from other licensed public telephone operators
     that are constructing their own facilities-based networks, cable
     companies and switch-based resellers, including the emerging German
     local exchange carriers known as "City Carriers."

Government Regulation

   As a global telecommunications company, we are subject to varying degrees
of regulation in each of the jurisdictions in which we provide services. Local
laws and regulations, and the interpretation of such laws and regulations,
differ significantly among the jurisdictions in which we operate. There can be
no assurance that future regulatory, judicial and legislative changes will not
have a material adverse effect on us, that domestic or international
regulators or third parties will not raise material issues with regard to our
compliance or noncompliance with applicable regulations or that regulatory
activities will not have a material adverse effect on us.

   Regulation of the telecommunications industry is changing rapidly both
domestically and globally. The Federal Communications Commission is
considering a number of international service issues in the context of several
policy rulemaking proceedings in response to specific petitions and
applications filed by other international carriers. We are unable to predict
how the FCC will resolve the pending international policy issues or how such
resolution will effect its international business. In addition, the World
Trade Organization Agreement, which reflects efforts to dismantle government-
owned telecommunications monopolies throughout Europe and Asia may affect us.
Although we believe that these deregulation efforts will create opportunities
for new entrants in the telecommunications service industry, there can be no
assurance that they will be implemented in a manner that would benefit us.

                                      70
<PAGE>


   The regulatory framework in certain jurisdictions in which we provide
services is described below:

 United States

   In the United States, our services are subject to the provisions of the
Communications Act of 1934, FCC regulations thereunder, as well as the
applicable laws and regulations of the various states and state regulatory
commissions.

   As a carrier offering services to the public, we must comply with the
requirements of common carriage under the Communications Act, including the
offering of service on a non-discriminatory basis at just and reasonable rates,
and obtaining FCC approval prior to any assignment of authorizations or any
transfer of de jure or de facto control of the company. We are classified as a
non-dominant common carrier for domestic service and are not required to obtain
specific prior FCC approval to initiate or expand domestic interstate services.

   International Service Regulation. International common carriers like us are
required to obtain authority under Section 214 of the Communications Act and
file a tariff containing the rates, terms, and conditions applicable to their
services prior to initiating their international telecommunications services.
We have obtained all required authorizations from the FCC to use, on a
facilities and resale basis, various transmission media for the provision of
international switched services and international private line services and
have filed a tariff.

   In addition to the general common carrier principles, we must conduct our
international business in compliance with the FCC's International Settlements
Policy, the rules that establish the permissible boundaries for U.S.-based
carriers and their foreign correspondents to settle the cost of terminating
each others' traffic over their respective networks.


   Domestic Service Regulation. We are considered a non-dominant domestic
interstate carrier subject to minimal regulation by the FCC. We are not
required to obtain FCC authority to expand our domestic interstate operations,
but we are required to maintain a tariff on file at the FCC, file various
reports and pay various fees and assessments. Among other things, interstate
common carriers must offer service on a nondiscriminatory basis at just and
reasonable rates. As a nondominant carrier, we are subject to the FCC's
complaint jurisdiction. In particular, we may be subject to complaint
proceedings in conjunction with alleged noncompliance such as unauthorized
changes in a customer's preferred carrier. The 1996 Telecommunications Act also
addresses a wide range of other telecommunications issues that may potentially
impact our operations.

   Our costs of providing long distance services will be affected by changes in
the access charge rates imposed by incumbent local exchange carriers for
origination and termination of calls over local facilities. The FCC has
significantly revised its access charge rules in recent years to permit
incumbent local exchange carriers greater pricing flexibility and relaxed
regulation of new switched access services in those markets where there are
other providers of access services. The FCC continues to adjust its access
charge rules and has indicated that it will promulgate additional rules
sometime in 1999 that may grant certain local exchange carriers further
flexibility.

   The FCC has also significantly revised the universal service subsidy regime
to be funded by interstate carriers, such as us, and certain other entities.
The FCC recently established new universal service funds to support qualifying
schools, libraries, and rural health care providers and expanded subsidies for
low income consumers. The FCC is continuing to revise its universal service
rules which may result in further substantial increases in the overall cost of
the subsidy program. The FCC order revising these funds is under appeal by the
U.S. Court of Appeals for the Fifth Circuit. The outcome of these proceedings
or their effect cannot be predicted.

   State Regulation. Our intrastate long distance operations are subject to
various state laws and regulations, including, in most jurisdictions,
certification and tariff filing requirements. Some states also require the
filing of

                                       71
<PAGE>


periodic reports, the payment of various fees and surcharges and compliance
with service standards and consumer protection rules. States often require
pricing approval or notification for certain stock or asset transfers or, in
several states, for the issuance of securities, debt or for name changes. We
have received the necessary certificate and tariff approvals to provide
intrastate long distance service in 48 states. Certificates of authority can
generally be conditioned, modified, canceled, terminated, or revoked by state
regulatory authorities for failure to comply with state law and/or the rules,
regulations, and policies of the state regulatory authorities. Fines and other
penalties also may be imposed for such violations. Public service commissions
also regulate access charges and other pricing for telecommunications services
within each state. The regional Bell operating companies and other local
exchange carriers have been seeking reduction of state regulatory requirements,
including greater pricing flexibility which, if granted, could subject us to
increased price competition. We may also be required to contribute to universal
service funds in some states.

   Wireless Service Regulations. Through TresCom, we hold a variety of wireless
licenses issued by the FCC. As a licensee authorized to provide microwave and
satellite earth station services, we are subject to Title III of the 1934
Communications Act and FCC regulations promulgated thereunder. All wireless
licenses are subject to foreign ownership restrictions. However, the
Communications Act permits licensees to seek a waiver of these restrictions
allowing 25% or greater indirect foreign ownership.

 Canada

   The operations of telecommunications carriers are regulated by the Canadian
Radio-television and Telecommunications Commission (CRTC), which has recently
established a new competitive regulatory framework governing the international
segment of the long-distance market, eliminating certain barriers to
competition, consistent with Canada's commitments in the World Trade
Organization Agreement. As a result, full facilities-based and resale
competition has been introduced in the provision of international services in
Canada, effective October 1, 1998, coincident with the elimination of traffic
routing limitations on switched hubbing through the United States. In addition,
foreign ownership rules for facilities-based carriers have now been waived in
relation to ownership of international submarine cables landed in Canada and
satellite earth stations used for telecommunications purposes. Effective
January 1, 1999, all international service providers must be licensed by the
CRTC under the Telecommunications Act of 1993, and we received our
international license as of December 23, 1998. Our international operations
will remain subject to conditions of our CRTC license, which address matters
such as competitive conduct and consumer safeguards, and to a regime of
contribution charges (roughly the equivalent of access charges in the U.S.).
The CRTC is currently conducting an examination of its international services
contribution regime in light of its recent decision to move from a per circuit
to a per minute contribution charge arrangement.

   Primus, as a reseller of domestic Canadian telecommunications, virtually is
unregulated by the CRTC. In particular, because we do not own or operate
transmission facilities in Canada, we are not subject to the Canadian
Telecommunications Act or the regulatory authority of the CRTC, except to the
extent that our provision of international telecommunications services is
subject to CRTC licensing and other regulations. Therefore we may provide
resold Canadian domestic long distance service without rate, price or tariff
regulation, ownership limitations, or other regulatory requirements.

   Competition. Long distance competition has been in place in Canada since
1990 for long distance resellers and since 1992 for facilities-based carriers.
Since 1994, the incumbent local exchange carriers have been required to provide
"equal access" which eliminated the need for customers of competitive long
distance providers to dial additional digits when placing long distance calls.
In June 1992, the CRTC issued its ground-breaking Telecom Decision CRTC 92-12
requiring the incumbent local exchange carriers to interconnect their networks
with their facilities-based as well as resale competitors. However, these
companies have now disbanded the Stentor alliance effective January 1, 1999,
and have begun to compete against one another. Other nationwide providers are
AT&T Canada Corp., and Sprint Canada. Additional long distance services
competition is provided by a substantial resale long distance industry in
Canada.

                                       72
<PAGE>


   Foreign Ownership Restrictions. Under Canada's Telecommunications Act and
certain regulations promulgated pursuant to such Act, foreign ownership
restrictions are applicable to facilities-based carriers (known as "Canadian
carriers"), but not resellers, which may be wholly foreign-owned and
controlled. These restrictions limit the amount of direct foreign investment in
Canadian carriers to no more than 20% of the voting equity of a Canadian
carrier operating company and no more than 33 1/3% of the voting equity of a
Canadian carrier holding company. The restrictions also limit the number of
seats which may be occupied by non-Canadians on the board of directors of a
Canadian carrier operating company to 20%. In addition, under Canadian law, a
majority of Canadians must occupy the seats on the board of directors of a
Canadian carrier holding company. Although it is possible for foreign investors
to also hold non-voting equity in a Canadian carrier, the law requires that the
Canadian carrier not be "controlled in fact" by non-Canadians.

 Australia

   The provision of our services is subject to federal regulation. The two
primary instruments of regulation are the Australian Telecommunications Act of
1997 and federal regulation of anti-competitive practices pursuant to the
Australian Trade Practices Act of 1974. The current regulatory framework came
into effect in July 1997.

   We are licensed under the Telecommunications Act of 1997 to own and operate
transmission facilities in Australia. Under the regulatory framework, we are
not required to maintain a carriage license in order to supply carriage
services to the public using network facilities owned by another carrier.
Instead, with respect to carriage services, we must comply with legislated
"service provider" rules contained in the Telecommunications Act of 1997
covering matters such as compliance with the Telecommunications Act of 1997,
operator services, regulation of access, directory assistance, provision of
information to allow maintenance of an integrated public number database, and
itemized billing.

   Two federal regulatory authorities exercise control over a broad range of
issues affecting the operation of the Australian telecommunications industry.
The Australian Communications Authority (ACA) is the authority regulating
matters including the licensing of carriers and technical matters, and the
Australian Competition and Consumer Commission (ACCC) has the role of promotion
of competition and consumer protection. We are required to comply with the
terms of our own license, are subject to the greater controls applicable to
licensed facilities-based carriers and are under the regulatory control of the
ACA and the ACCC. In addition, other federal legislation, various regulations
pursuant to delegated authority and legislation, ministerial declarations,
codes, directions, licenses, statements of Australian government policy and
court decisions affecting telecommunications carriers also apply to us.

   There is no limit to the number of carriers who may be licensed. Any company
that meets the relevant financial and technical standards and complies with the
license application process can become a licensed carrier permitted to own and
operate transmission facilities in Australia. Carriers are licensed
individually, are subject to charges that are intended to cover the costs of
regulating the telecommunications industry, and are obliged to comply with
license conditions (including obligations to comply with the Telecommunications
Act of 1997, with certain commitments made in their industry development plan
and with the telecommunications access regime and related facilities access
obligations). Carriers also must meet the universal service obligation, to
assist in providing all Australians, particularly in remote areas, with
reasonable access to standard telephone services. The levy required to be paid
by in connection with this obligation has been set previously at a level that
is not material. The levy is currently under review. The outcome from the
Australian Communications Authority's assessment and the Australian
Government's policy considerations is expected to result in a levy that will
not be material for us. However, there can be no guarantee that the Australian
Communications Authority will not make an assessment of a universal service
levy that would be material or that the Australian Government will not
legislate for an outcome that would be material.

   Fair Trading Practices. The ACCC enforces legislation for the promotion of
competition and consumer protection, particularly rights of access (including
pricing for access) and interconnection. The ACCC can issue

                                       73
<PAGE>

a competition notice to a carrier which has engaged in anti-competitive
conduct. Where a competition notice has been issued, the ACCC can seek
pecuniary penalties, and other carriers can seek damages, if the carrier
continues to engage in the specified conduct.

   The Telecommunications Act of 1997 package of legislation includes a
telecommunications access regime that provides a framework for regulating
access rights for specific carriage services and related services through the
declaration of services by the ACCC. The regime establishes mechanisms within
which the terms and conditions of access can be determined. The Australian
government intends the access regime to reduce the power of Telstra and Cable &
Wireless Optus (as the former protected fixed line carriers) and other carriers
who may come to own or control important infrastructure or services necessary
for competition.

   The access regime establishes a mechanism for the industry to develop an
access code containing model terms and conditions for access to particular
declared services. Once approved by the ACCC, those model terms and conditions
may be adopted in an undertaking by individual carriers who are under an access
obligation.

   In July 1997, the Australian government mandated that Telstra provide access
to its facilities at specified rates to other service providers including us.
We have negotiated access arrangements with Telstra in substitution for certain
mandated arrangements.

   Foreign Ownership Limitations. Foreign investment in Australia is regulated
by the Foreign Acquisitions and Takeovers Act 1975. We notified the Australian
government of our proposed acquisition of Axicorp in 1996 and were informed at
that time that there were no objections to the investment in terms of
Australia's foreign investment policy. There can be no assurance, however, that
additional foreign ownership restrictions will not be imposed on the
telecommunications industry or other foreign investors, including us, in the
future.

 Japan

   Our services in Japan are subject to regulation by the Japanese Ministry of
Post and Telecommunications under the Japanese Telecommunications Business Law.
We have obtained licenses as a Type I business, and as a Special Type II
business, and also as a General Type II business through the Telegroup
acquisition. Our licenses allow us to provide selected international
telecommunications services using our own facilities, as well as leased
facilities, and domestic telecommunications services using leased facilities.
There can be no guarantee that the Japanese regulatory environment will allow
us to provide service in Japan at competitive rates.

 European Union

   In Europe, the regulation of the telecommunications industry is governed at
a supra national level by the European Commission, consisting of members from
the following countries: Austria, Belgium, Denmark, Finland, France, Germany,
Greece, Ireland, Italy, Luxembourg, the Netherlands, Portugal, Spain, Sweden
and the United Kingdom, which is responsible for creating pan-European policies
and, through legislation, developing a regulatory framework to ensure an open,
competitive telecommunications market.

   In March 1996, the EU adopted the Full Competition Directive containing two
provisions which required EU member states to allow the creation of alternative
telecommunications infrastructures by July 1, 1996, and which reaffirmed the
obligations of EU member states to abolish the post, telephone and telegraph
operators' monopolies in voice telephony by 1998. Certain EU countries were
allowed to delay the abolition of the voice telephony monopoly based on
derogations established in the Full Competition Directive. These countries
include Luxembourg (July 1, 1998), Spain and Ireland (which were liberalized on
December 1, 1998), Portugal (January 1, 2000) and Greece (December 31, 2000).

   Each EU member state in which we currently conduct or plan to conduct our
business has a different regulatory regime and such differences have continued
beyond January 1998. The requirements for us to obtain

                                       74
<PAGE>


necessary approvals vary considerably from country to country and are likely to
change as competition is permitted in new service sectors. Most EU member
states require companies to obtain a license in order to provide voice
telephony services or construct and operate telecommunications networks.
However, the EU generally does not permit its member states to require
individual licenses for other types of services. In addition, we have obtained
and will continue to seek to obtain interconnection agreements with other
carriers within the EU. While EU directives require that dominant carriers
offer cost-based and nondiscriminatory interconnection to competitors,
individual EU member states have implemented and may implement this requirement
differently. As a result, we may be delayed in obtaining or may not be able to
obtain interconnection in certain countries that would allow us to compete
effectively. Moreover, there can be no guarantee that long distance providers
like us will be able to afford customers "equal access" to their networks, and
the absence of such equal access could put such long distance companies at a
disadvantage with respect to existing post, telephone and telegraph operators.


 United Kingdom

   Our services are subject to the provisions of the United Kingdom
Telecommunications Act. The Secretary of State for Trade and Industry, acting
on the advice of the United Kingdom Department of Trade and Industry, is
responsible for granting UK telecommunications licenses, while the Director
General of Telecommunications and Oftel are responsible for enforcing the terms
of such licenses. Oftel attempts to promote effective competition both in
networks and in services to redress anti-competitive behavior.

   In 1991, the British government established a "multi-operator" policy to
replace the duopoly that had existed between British Telecom and Cable and
Wireless Communications. Under the multi-operator policy, the Department of
Trade and Industry recommends the grant of a license to operate a
telecommunications network to any applicant that it believes has a reasonable
business plan and where there are no other overriding considerations not to
grant such license. All public telecommunications operators and international
simple voice resellers operate under individual licenses granted by the
Secretary of State for Trade and Industry pursuant to the United Kingdom
Telecommunications Act. Any telecommunications system with compatible equipment
that is authorized to be run under an individual license is permitted to
interconnect to British Telecom's network. As of June 30, 1999, only those
systems providing bearer services will be entitled to interconnection,
providing the operator has been registered in Annex II. Under the terms of
British Telecom's license, it is required to allow any such licensed operator
to interconnect its system to British Telecom's system, unless it is not
reasonably practicable to do so (e.g., due to incompatible equipment).

   Our subsidiary, Primus Telecommunications Limited, holds a license that
authorizes it to provide switched voice services over leased private lines to
all international points. In addition, Primus Telecommunications Limited has
received a license from the United Kingdom's Secretary for Trade and Industry
to provide international facilities-based voice services to all international
points from the United Kingdom. This license also allows the holder to acquire
ownership interests in or construct the United Kingdom half circuit of any IRU
as well as backhaul facilities. The international facilities-based license
together with the international simple resale license authorize the provision
of every voice and data service, except the provision of broadcasting and
mobile services. While the international facilities-based license authorizes us
to acquire ownership interests in the United Kingdom half-circuit of satellite
space segment in order to provide satellite-based services, it is also
necessary to apply for a Wireless Telegraphy Act 1949 License which authorizes
the use of the spectrum.

   Telegroup Network Services Ltd. holds an ISVR license granted on December
31, 1997 and Telegroup UK Ltd. holds an international facilities-based license
granted on December 30, 1997.

   Tariffs. Telecommunications tariffs on operators in the United Kingdom
(excluding British Telecom) are generally not subject to prior review or
approval by regulatory authorities, although Oftel has historically imposed
price caps on British Telecom. British Telecom has advocated and will likely
continue to advocate for

                                       75
<PAGE>


greater pricing flexibility, including flexibility for pricing toll free and
other services. Greater pricing flexibility could allow British Telecom to
charge us higher prices for certain services or to charge end user customers
prices that are lower than we are able to charge.

   Interconnection and Indirect Access. We must interconnect our U.K. network
to networks of other service providers in the United Kingdom and allow our end
user customers to obtain access to our services in order to compete effectively
in the United Kingdom. In the United Kingdom, licensed long distance carriers
like us can obtain interconnection to British Telecom at cost-based rates.
However, while customers of British Telecom's long distance service can access
that service automatically (i.e., without dialing additional digits), customers
of other long distance carriers generally must dial additional digits to access
their chosen carrier's services.

   Fair Trading Practices. Oftel is the principal regulator of the competitive
aspects of the United Kingdom telecommunications industry. There are no foreign
ownership restrictions that apply to telecommunications company licensing in
the United Kingdom although the Department of Trade and Industry does have a
discretion as to whether to award licenses on a case by case basis. We also are
subject to general European law, which, among other things, prohibits certain
anti-competitive agreements and abuses of dominant market positions through
Articles 81 and 82 of the Treaty of Rome.

 Germany

   The German Telecommunications Act of 1996 liberalized all telecommunications
activities as of January 1, 1998. The German Telecom Act has been complemented
by several ordinances.

   Under the German regulatory scheme, licenses are required for the operation
of infrastructure and the provision of voice telephony services. Licenses
required for the operation of infrastructure are divided into 3 license
classes: mobile telecommunications (license class 1); satellite (license class
2); and other telecommunications services for the general public (license class
3). In addition to the infrastructure licenses, a separate license is required
for provision of voice telephony services to the general public on the basis of
self-operated telecommunications networks (license class 4). A class 4 license
does not include the right to operate transmission infrastructure. All other
telecommunications services (e.g. valued-added, data, etc.) are only subject to
a notification requirement. We operate under a line license class 4 which has
been extended to a Germany-wide area license.

   Under the German Telecom Act, companies that desire to connect with Deutsche
Telekom's network must enter into an interconnection agreement with the
regulated interconnection tariffs. We entered into an interconnection agreement
with Deutsche Telekom on February 27, 1998 at the regulated standard
interconnection rates presently under court review. Our interconnection
agreement with Deutsche Telekom permits the parties to renegotiate
interconnection rates or other provisions of the agreement in the event of a
change in the German regulatory environment or other circumstances which have a
bearing on the economic basis of the interconnection agreement or a party's
license situation or which are considered by both parties to materially affect
the interconnection agreement in any other way. The interconnection agreement
may also be terminated by commencing a six month notice period at the end of
the calendar year. After the public announcement on December 15, 1998, Deutsche
Telekom, by letter of December 23, 1998, informed us that, as a matter of
precaution, it terminated the interconnection agreement as of December 31, 1999
and it asked that renegotiations be opened.

   Several complaints, the outcome of which may affect our business, currently
are pending before the Regulierungsbehorde fur Telekommunikation und Post
(RegTP) or German courts concerning interconnection with Deutsche Telekom.
Since Deutsche Telekom and some of its major competitors in Germany have been
unable to reach agreement on interconnection rates, the RegTP established
provisional interconnection tariffs in September 1997 which Deutsche Telekom
has since challenged in court. These rates are now part of the standard offer
of Deutsche Telekom and are valid for all interconnected and licensed carriers
for as long as the

                                       76
<PAGE>


matter is pending before the German courts. Court review of these rates may
result in higher rates being imposed on network operators retroactively as the
standard interconnection agreement provides for retroactive effect of the
court's final decision. Other pending complaints concern the costs of billing
services provided by Deutsche Telekom to other carriers and rates for direct
access to the end-user lines of Deutsche Telekom. It is expected that a final
resolution to these matters will take several years.

   Due, in part, to Deutsche Telekom's refusal, since March 1998, to conclude
interconnection agreements with long-distance operators, the RegTP initiated a
public hearing concerning the prerequisites for interconnection under the
German Telecom Act. The preliminary results were presented to the general
public in a hearing on December 15, 1998 and have been confirmed and published.
Accordingly, the RegTP regards an operator that requests three points of
interconnection directed by one switch and three leased lines connecting these
three points of interconnection as a carrier operating a public
telecommunications network as defined in the German Telecom Act and as such
they are entitled to interconnection based on the regulated tariffs. Deutsche
Telekom has filed an application requesting such surcharges to be imposed on
all operators who have not signed the new interconnection agreement requiring
operators to install additional points of interconnection and meet minimum
traffic requirements to avoid atypical traffic. Deutsche Telekom uses the term
"atypical traffic" to denote what it perceives an inefficient traffic caused by
long-distance operators with only a few interconnection points with Deutsche
Telekom. According to Deutsche Telekom, traffic originating outside the long
distance network's geographic reach is transported through Deutsche Telekom's
network to the long distance network's closest switch and back again to be
terminated in Deutsche Telekom's network. In extreme cases this may multiply
the distance a single call travels as compared to the case where the same call
would have been routed more or less directly to its destination through
Deutsche Telekom's or any other large network. Deutsche Telekom has claimed
that this type of traffic jams its network and requires otherwise unnecessary
investments into surplus capacity.

   In May 1999, the RegTP turned down Deutsche Telekom's applications for
regulatory approval of surcharges for atypical traffic and its application for
interconnection orders, including a 24-month minimum lease of interconnection
lines and minimum traffic requirements, with regard to its 1999 interconnection
agreements. However, the RegTP affirmed our obligation to install additional
points of presence to the extent we exceed certain traffic volumes. New
(possibly higher) interconnection fees, surcharges for small network operators,
minimum traffic requirements and longer minimum lease requirements may be
reintroduced in connection with the upcoming new interconnection regime 2000.

   Deutsche Telekom has presented a new draft interconnection agreement subject
to the upcoming negotiations. The new interconnection offer is based generally
on less favorable terms than the current one. These less favorable conditions
may run counter to the outcome of the regulatory proceedings in May 1999 as
described above. In addition, the RegTP may redesign the interconnection rules
applicable in 2000. We cannot predict the results of this upcoming new
interconnection regulation, but the results may severely affect our business in
Germany.

   Further, the general price depression in the end-customer market along with
the fact that the RegTP has authorized Deutsche Telekom's price cuts in the
end-customer market (announced to be effective as of January 1 and April 1,
1999) may adversely affect us. Other large operators also have reduced their
prices which may adversely affect our business.

   We are or may become subject to certain other requirements as a licensed
telecommunications provider in Germany. For example, licensed providers are
under an obligation to present their standard terms and conditions to the
RegTP. The RegTP may, based upon certain criteria, decide not to accept these
terms and conditions. We also may become subject to universal service financing
obligations. Currently, it is unlikely that the universal service financing
system will be implemented in Germany in the foreseeable future. However, in
the event that the system is implemented, we could be subject to such universal
service requirements and financing schemes if we at that time should have a
market share in Germany of at least 4%.

 France

   The French Telecommunications Act of 26 July 1996 further developed the new
legal framework for the development of a competitive telecommunications market
in France.

   As a result, the French Regulator (Autorite de Regulation des
Telecommunications) was created on January 1, 1997 with the task of overseeing
the development of a competitive telecommunications sector which would provide
benefits to the user. In addition, the monopoly on the provision of voice
telephony services to the public was abolished as of January 1, 1998.

   Under the French regulatory regime, an L33.1 licence is required for the
establishment and running by the operator of a telecommunications network open
to the public (an "infrastructure licence") and the provision of public voice
telephony services requires an L34.1 licence. An infrastructure licence is
required by those operators who wish to install or purchase dark fiber for the
running of a network. As with the L34.1 voice licence, L33.1 infrastructure
licences are granted on a regional or nation-wide basis and it is possible to
be granted a licence just for the region of Paris and its suburbs. We (via our
French subsidiary) were awarded the first L34.1 only license on May 29, 1998.
Call back operators and least cost routing operators not using their own leased
lines as defined by the French Regulator, do not need to apply and obtain an
L34.1 licence. Certain competitors obtained a joint L34.1 & L33.1 licence and
we are considering applying for an L33.1 licence in addition to our L34.1
license so that we can benefit from the lower interconnection tariffs afforded
to L33.1 infrastructure license holders.

   Because we hold a nation-wide class L34.1 licence, we have the authority to
originate and terminate calls throughout France.

   Companies that desire to interconnect with France Telecom's network must
enter into an interconnection agreement which applies certain fixed
interconnection tariffs set out in an interconnection catalog. In order to
obtain the lowest available interconnection tariffs throughout France, we would
need to obtain a nation-wide infrastructure licence and install dark fiber and
points of interconnection in all the different French regions (a minimum of 18
regions) where we are to be originating and terminating traffic.

   We have entered into an interconnection agreement with France Telecom at the
regulated standard interconnection rates applicable to L34.1 voice licence
holders set out in the interconnection catalog. In order to interconnect with
France Telecom, we are required to install, in addition to our principal switch
in the city of Paris, a second point of presence to be interconnected with
France Telecom in the outer zone of the Parisian region as defined for
telecommunications purposes. We have located a site for our principal Ericsson
AXE-10 switch and have ordered the leased lines from France Telecom to
interconnect our switch with the most convenient France Telecom points of
interconnection. France Telecom estimates and sets out in the interconnection
agreement that leased lines so requested will be provided within a period of 6
to 18 months.

   It is possible that the licence fees currently paid could be further
increased. In addition, the interconnection fees payable to France Telecom
include an element relating to the funding of France Telecom's universal
service financing obligations, and it is possible that the levels of such
contributions will be raised in the foreseeable future.

   We have been granted the 1656 four digit indirect access code; however,
there have been seven one digit indirect access numbers granted to other
telecommunications providers in France. Those operators with a one digit access
number will have a competitive advantage. It is highly unlikely that we will be
able to obtain a one digit access number.

   The Telegroup French subsidiary holds a mixed voice and infrastructure
license and has been allocated the 1633 carrier selection code. We understand
that this Telegroup subsidiary employs over 10 employees and has entered into a
number of contracts with other telecom operators in France. It has also
contracted with France Telecom for the use of two "3PBQ" numbers which are the
equivalent of four digit freephone access numbers

                                       78
<PAGE>


for use in regions where the carrier selection code is not operational due to
the lack of a point of interconnection. Primus is in the process of determining
whether to maintain its separate license and carrier selection code, in light
of those held by Telegroup.

 Latin America

   Various countries in Latin America have taken initial steps towards
deregulating their telecommunications markets. Each Latin American country has
a different national regulatory regime and each country is in a different stage
of liberalization. Historically, Latin American countries have reserved the
provision of voice services to the state-owned post, telegraph and telephone
operators. In the last few years, several Latin American countries have
privatized completely or partially their national carriers, including
Argentina, Chile, Mexico, Peru and Venezuela. In addition, certain countries
have opened partially or completely their local and/or long distance markets,
most notably Chile, which has competitive operators in all sectors. Argentina
has liberalized certain telecommunications services, such as value-added,
paging, data transmission, and personal communications services. Brazil
currently is in the process of opening its telecommunications market to
competition. Brazil intends to privatize Telecomunicas Brasileras S.A.
(Telebras), which, through its 28 regional subsidiaries, holds a monopoly over
the provision of local telephone services, as well as Empresa Brasiliera de
Telecomunicacoes S.A., the monopoly provider of long distance and international
telephone services. Moreover, Colombia recently has opened national and
international long distance services to competition, and has awarded two new
concessions for the provision of these services to two major local exchange
carriers in Colombia--Empresa Brasiliera de Telecomunicaciones S.A. de Bogota
and Orbitel, S.A. In Colombia the provision of value-added services and voice
services to closed-user groups is open to competition. Mexico initiated
competition in the domestic and international long distance services market on
January 1, 1996, which are subject to a concession requirement. In addition,
the Mexican government has opened recently basic telephony, and currently is
auctioning radio-electric spectrum frequencies for the provision of personal
communications services and Local Multipoint Distribution System Services.
Value-added services are also fully open to competition in Mexico. Finally, in
the Central American region, Guatemala and El Salvador recently have opened
their telecommunications market to competition, abolishing all restrictions on
foreign investment in this sector. Other countries in Central America, such as
Nicaragua and Honduras, are in the process of privatizing their state-owned
carriers, and have not opened fully their markets to competition.

   We have never experienced a work stoppage, and none of our employees are
represented by a labor union or covered by a collective bargaining agreement.
We consider our employee relations to be excellent.

Properties

   We currently lease our corporate headquarters which is located in McLean,
Virginia. Additionally, we also lease administrative, technical and sales
office space, as well as space for our switches, in various locations in

                                       79
<PAGE>


the countries in which we operate, including the United States, Canada,
Australia, the United Kingdom, Canada, Japan, Mexico, Germany and France. Total
leased space approximates 350,000 square feet and the total annual lease costs
are approximately $7.0 million. The operating leases expire at various times
through 2008. Certain communications equipment which includes network switches
and transmission lines are leased through operating and capital leases. We
believe that our present administrative and sales office facilities are
adequate for our anticipated operations and that similar space can readily be
obtained as needed. We further believe that the current leased facilities are
adequate to house existing communications equipment. However, as our network
grows, we expect to lease additional locations to house the new equipment.

Legal Proceedings

   We are from time to time involved in litigation incidental to the conduct of
its business. We believe the outcome of pending legal proceedings to which we
are a party will not have a material adverse effect on our business, financial
condition, results of operation, or cash flows.

founder, Chairman, President and CEO of GlobeComm Systems, Inc., a system
integrator of satellite earth stations. From 1976 to 1994, Mr. Hershberg was
the President and Chief Executive Officer of Satellite Transmission Systems,
Inc., a global provider of satellite telecommunications equipment, and became a
Group President of California Microwave, Inc., a company that acquired
Satellite Transmission Systems, Inc.

   Douglas M. Karp became a director Primus in June 1998. Mr. Karp has been a
Managing Director of E.M. Warburg, Pincus & Co., LLC (or its predecessor, E.M.
Warburg, Pincus & Co., Inc.) since May 1991. Prior to joining E.M. Warburg,
Pincus & Co., LLC, Mr. Karp held several positions with Salomon Inc. including
Managing Director from January 1990 to May 1991, Director from January 1989 to
December 1989 and Vice President from October 1986 to December 1988. Mr. Karp
is a director of Qwest, TV Filme, Inc., Journal Register Company, PageNet do
Brasil, S.A., StarMedia Network Inc. and several privately held companies.

   John G. Puente became a director of Primus in 1995. From 1987 to 1995, he
was Chairman of the Board and CEO of Orion Network Systems, a satellite
telecommunications company. Mr. Puente is currently Chairman of the Board of
Telogy Networks, Inc., a privately-held company, and a director of MICROS
Systems, Inc. Prior to joining Orion, Mr. Puente was Vice Chairman of M/A-Com
Inc., now known as Hughes Network Systems, Inc., a diversified
telecommunications and manufacturing company, which he joined in 1978 when M/A-
Com acquired Digital Communications Corporation, a satellite terminal and
packet switching manufacturer of which Mr. Puente was a founder and Chief
Executive Officer.

   Under the terms of a shareholders' agreement entered into in connection with
the TresCom merger among Primus, Warburg, Pincus and Mr. Singh, we have agreed
to nominate one individual selected by Warburg, Pincus and reasonably
acceptable to our non-employee directors, to serve as a member of the Primus
board of directors. The foregoing nomination right remains effective so long as
Warburg, Pincus is the beneficial owner of 10% or more of our outstanding
common stock. In June 1998, Mr. Karp joined the Primus board of directors
pursuant to the foregoing arrangement.

Classified Board of Directors

   Pursuant to our By-Laws, the board of directors is divided into three
classes of directors each containing, as nearly as possible, an equal number of
directors. Directors within each class are elected to serve three-year terms
and approximately one-third of the directors sit for election at each annual
meeting of the our stockholders. A classified board of directors may have the
effect of deterring or delaying any attempt by any group to obtain control of
Primus by a proxy contest since such third party would be required to have its
nominees elected at two separate annual meetings of the board of directors in
order to elect a majority of the members of the board of directors. Directors
who are elected to fill a vacancy (including vacancies created by an increase
in the number of directors) must be confirmed by the stockholders at the next
annual meeting of stockholders whether or not such director's term expires at
such annual meeting.

Compensation of Directors

   Directors are paid an annual fee of $10,000 and receive reimbursement of
their expenses for attending meetings. In addition, we grant each person who
becomes an Eligible Director (as defined in the Director Option Plan) options
to purchase 15,000 shares of our common stock pursuant to the Director Option
Plan. These options vest one-third upon the grant date, and one-third on each
of the first and second anniversary of the grant dates. We did not grant any
such options in 1997 or 1998.

Committees of the Board

   Our board of directors has appointed an Audit Committee, Nominating
Committee and a Compensation Committee.

   Audit Committee. The Audit Committee, which currently consists of Mr. Puente
and Mr. Fialkov, has the authority and responsibility: to hire one or more
independent public accountants to audit our books, records and financial
statements and to review our systems of accounting (including our systems of
internal control); to discuss with such independent public accountants the
results of such audit and review; to conduct periodic independent reviews of
the systems of accounting (including systems of internal control); and to make
reports periodically to the board of directors with respect to its findings.

   Nominating Committee. The Nominating Committee, which currently consists of
Messrs. Puente (Chairman) and Singh, is responsible for selecting those persons
to be nominated to our board of directors.

   Compensation Committee. The Compensation Committee, which currently consists
of Messrs. Fialkov (Chairman) and Hershberg, is responsible for fixing the
compensation of the Chief Executive Officer and the other executive officers,
deciding other compensation matters such as those relating to the operation of
our Employee Stock Option Plan and Director Stock Option Plan, including the
award of options under the Employee Stock Option Plan, and approving certain
aspects of our management bonus plan.

Compensation Committee Interlocks and Insider Participation

   The Compensation Committee of the Board consists of Messrs. Fialkov and
Hershberg, who were not at any time officers or employees of Primus. No
executive officer of Primus serves as a member of the board of directors or
compensation committee of another entity which has one or more executive
officers that will serve as a member of the Primus Board or the Primus
Compensation Committee.

Stock Options Granted to Certain Executive Officers During Last Fiscal Year

   Under the Employee Stock Option Plan, options to purchase our common stock
are available for grant to selected employees. Options are also available for
grant to eligible directors under our Director Stock Option Plan. No options
for the purchase of our common stock were awarded to the executive officers
named on the above summary compensation table during 1998.

Stock Plans

   Employee Stock Option Plan. We established the Employee Stock Option Plan
for our employees and consultants on January 2, 1995. Recently, our board
adopted and the stockholders approved an amendment to the Employee Stock Option
Plan that, among other things, increased the number of options available for
grant and expanded the category of plan participants. The Employee Stock Option
Plan provides for the grant to selected full and part-time employees and
consultants of Primus and its subsidiaries who contribute to the development
and success of Primus and its subsidiaries of both "incentive stock options"
within the meaning of Section 422 of the Code (ISOs) and options that are non-
qualified for federal income tax purposes (NQSOs); provided, however, that
consultants are eligible for the grant of NQSOs only. The total number of
shares of our common stock for which options may be granted pursuant to the
Employee Stock Option Plan is 5,500,000, of which 1,427,368 are available for
future grants, subject to certain adjustments reflecting changes in our
capitalization. No individual may receive, over the term of the Employee Stock
Option Plan, options for more than an aggregate of 25% of the shares authorized
for grant under the Employee Stock Option Plan. The Employee Stock Option Plan
is currently administered by the Compensation Committee of our board of
directors which is comprised of directors who are not also our employees. The
Compensation Committee determines, among other things:

  .  which employees and consultants will receive options under the Employee
     Stock Option Plan,

  .  the time when options will be granted,

                                       84
<PAGE>

  .  the type of option (ISO or NQSO, or both) to be granted,

  .  the number of shares subject to each option,

  .  the time or times when the options will become exercisable and expire,
     and

  .  subject to certain conditions discussed below, the option price and
     duration of the option.

Members of our board of directors administering the Employee Stock Option Plan
may vote on any matters affecting the administration of the Employee Stock
Option Plan, except that no member may act upon the granting of an option to
himself or herself.

   The exercise price of the options granted under the Employee Stock Option
Plan is determined by our board of directors, but may not be less than the fair
market value per share of our common stock on the date the option is granted.
If, however, an ISO is granted to any person who, at the time of the grant,
owns capital stock possessing more than 10% of the total combined voting power
of all classes of our capital stock, then the exercise price for such ISO may
not be less than 110% of the fair market value per share of our common stock on
the date the option is granted. Our board of directors also determines the
method of payment for the exercise of options under the Employee Stock Option
Plan. Payment may consist entirely of cash, check, promissory notes or our
common stock having a fair market value on the date of surrender equal to the
aggregate exercise price. Our board of directors, in its sole discretion, may
cooperate with an optionee to complete a cashless exercise transaction.

   Options are not assignable or transferrable other than by will or the laws
of descent and distribution. In general, if an employee's employment or a
consultant's engagement is terminated for any reason, such employee's or
consultant's options exercisable on the date of termination are exercisable for
three months following the date of termination. If our board of directors makes
a determination that a terminated employee or consultant engaged in disloyalty
to us, disclosed proprietary information, is convicted of a felony, or breached
the terms of a written confidentiality agreement or non-competition agreement,
all unexercised options held by such employee or consultant terminate upon the
earlier of the date of such determination or the date of termination. If the
employment or service of an employee or consultant terminates because of
disability or death, such employee's or consultant's options that are
exercisable on the date of disability or death will remain exercisable for 12
months following the date of disability or death; provided, however, that if a
disabled employee or consultant commences employment or service with one of our
competitors during that 12-month period, all options held by the employee or
consultant terminate immediately.

   Options issued pursuant to the Employee Stock Option Plan outstanding on the
date of a "change in control" of Primus become immediately exercisable on such
date. A change in control for purposes of the Employee Stock Option Plan
includes the acquisition by any person or entity of the beneficial ownership of
50% or more of the voting power of our common stock, the approval by the our
stockholders of a merger, reorganization or consolidation in which our
stockholders do not own 50% or more of the voting power of the stock of the
entity surviving such transaction, the approval of our stockholders of an
agreement of sale of all or substantially all of our assets, and the acceptance
by our stockholders of a share exchange in which our stockholders do not own
50% or more of the voting power of the stock of the entity surviving such
exchange.

   There are no federal income tax consequences to Primus on the grant or
exercise of an ISO. If an employee disposes of stock acquired through the
exercise of an ISO within one year after the date such stock is acquired or
within two years after the grant of the ISO (a Disqualifying Disposition), we
will be entitled to a deduction in an amount equal to the difference between
the fair market value of such stock on the date it is acquired and the exercise
price of the ISO. There are no tax consequences to Primus if an ISO lapses
before exercise or is forfeited. The grant of a NQSO has no immediate tax
consequences to Primus. Upon the exercise of a NQSO by an employee or
consultant, we are entitled to a deduction in an amount equal to the difference
between the fair market value of the share acquired through exercise of the
NQSO and the exercise price of the NQSO. There are no tax consequences to
Primus if a NQSO lapses before exercise or is forfeited.

                                       85
<PAGE>

   An employee who receives an ISO is not subject to federal income tax on the
grant or exercise of the ISO; however, the difference between the option price
and the fair market value of our common stock received on the exercise of the
ISO is an adjustment for purposes of the alternative minimum tax. Upon the
exercise of an ISO, an employee will have a basis in the common stock received
equal to the amount paid. An employee will be subject to capital gain or loss
upon the sale of such common stock, unless such sale constitutes a
Disqualifying Disposition, equal to the difference between the amount received
for the stock and the employee's basis in such. The gain or loss will be long-
or short-term, depending on the length of time the common stock received from
the exercise of the ISO was held prior to disposition. There are no tax
consequences to an employee if an ISO lapses before exercise or is forfeited.

   In the event of a Disqualifying Disposition, an employee will be required to
recognize:

     (1) taxable ordinary income in an amount equal to the difference between
  the fair market value of the ISO Stock on the date of exercise of the ISO
  and the exercise price; and

     (2) capital gain or loss (long- or short-term, as the case may be) in an
  amount equal to the difference between

       (a) the amount realized by the employee upon the Disqualifying
    Disposition and

       (b) the exercise price paid by the employee for the stock, increased
    by the amount of ordinary income recognized by the employee, if any.

If the disposition generates an allowable loss (e.g., a sale to an unrelated
party not within 30 days of purchase of our common stock), then the amount
required to be recognized by the employee as ordinary income will be limited to
the excess, if any, of the amount realized on the sale over the basis of the
stock.

   The Employee Stock Option Plan allows an employee or consultant to pay an
exercise price in cash or shares of our common stock. If the employee pays with
shares of our common stock that are already owned, the basis of the newly
acquired common stock will depend on the tax character and number of shares of
the previously owned stock used as payment. If an employee pays with shares
acquired upon other than the exercise of an ISO, the transaction will be tax-
free to the extent that the number of shares received does not exceed the
number of shares paid. The basis of the number of shares of newly acquired
common stock which does not exceed the number of shares of common stock paid
will be equal to the basis of the shares paid. The employee's holding period
with respect to such shares will include the holding period of the shares of
common stock paid. To the extent that the employee receives more new shares
than shares surrendered, the "excess" shares of common stock will take a zero
basis. If an employee exercises an ISO by using stock that is previously
acquired from the exercise of an ISO, however, certain special rules apply. If
the employee has not held the previously acquired common stock for at least two
years from the date of grant of the related ISO and one year from the date the
employee acquired the previously acquired common stock, the use of such common
stock to pay the exercise price will constitute a Disqualifying Disposition and
subject the employee to income tax with respect to the common stock as
described above. In such circumstances, the basis of the newly acquired common
stock will be equal to the fair market value of the previously acquired common
stock used as payment.

   The grant of a NQSO has no immediate tax consequences to an employee or
consultant. The exercise of a NQSO requires an employee or consultant to
include in gross income the amount by which the fair market value of the
acquired shares exceeds the exercise price on the exercise date. We are
required to withhold income and employment taxes from an employee's wages on
account of this income. The employee's or consultant's basis in the acquired
shares will be their fair market value on the date of exercise. Upon a
subsequent sale of such shares, the employee or consultant will recognize
capital gain or loss equal to the difference between the sales price and the
basis in the stock. The capital gain or loss will be long- or short-term,
depending on whether the employee or consultant has held the shares for more
than one year. There are no tax consequences to an employee or consultant if a
NQSO lapses before exercise or is forfeited. If an employee or consultant uses
previously owned common stock as payment for the exercise price of a NQSO, to

                                       86
<PAGE>

the extent the employee or consultant surrenders the same number of shares
received, the exchange is tax-free and the new shares will have a basis equal
to that of the shares surrendered. The holding period for the new shares will
include the period the employee or consultant held the surrendered shares. To
the extent the employee or consultant receives more new shares than shares
surrendered, the excess shares are treated as having been acquired for no
consideration and the fair market value of such excess shares is includible in
the employee's or consultant's income as compensation. The basis of the excess
shares is their fair market value at the time of receipt. If the previously
owned shares consist of common stock from the exercise of an ISO for which the
holding requirements were not met such that their use as payment of the
exercise price constituted a Disqualifying Disposition, the employee will have
the income tax consequences described above.

   Our board of directors has authority to suspend, terminate or discontinue
the Employee Stock Option Plan or revise or amend it in any manner with respect
to options granted after the date of revision. No such revision, however, can
change the aggregate number of shares subject to the Employee Stock Option
Plan, change the designation of employees eligible thereunder, or decrease the
price at which options may be granted. Our board of directors may not grant any
options under the Employee Stock Option Plan after January 2, 2005.

   TresCom International Stock Option Plan. In connection with the TresCom
merger, we assumed a stock option plan previously sponsored by TresCom.
Pursuant to the terms of the agreement governing the TresCom merger, each
outstanding option to acquire one share of TresCom common stock was converted
into an option to acquire 0.6147 shares of our common stock. Options to acquire
136,816 shares of our common stock are outstanding under this Primus-TresCom
Option Plan. The Primus-TresCom Option Plan provides for an equitable
adjustment in the number and price of shares of our common stock with respect
to outstanding options in the event the outstanding shares of our common stock
are increased or decreased through stock dividends, recapitalizations,
reorganizations or similar things.

   The Primus-TresCom Option Plan is intended as an incentive and to encourage
stock ownership by the officers, key employees, consultants and directors of
TresCom prior to the TresCom merger in order to increase their proprietary
interest in our success and to encourage them to continue to provide services
to us. No additional stock options will be granted under the Primus-TresCom
Option Plan. All options issued under the Primus-TresCom Option Plan are
entirely vested and exercisable in full.

   The Primus-TresCom Option Plan is administered by our board of directors or
by a committee appointed by our board of directors and consisting of not less
than two members of our board of directors who are not also employees of Primus
or any of its subsidiaries. The Primus-TresCom Option Plan does not limit the
length of time a director may serve as part of this committee. Subject to the
terms of the Primus-TresCom Option Plan, the board of directors or this
committee will have the exclusive authority to interpret, administer and make
determinations under the Primus-TresCom Option Plan. All options granted under
the Primus-TresCom Option Plan are in the form of ISOs. Payment for the shares
of our common stock purchased under an option must be made in full upon
exercise of the option, by certified or bank cashier's check or by any other
means acceptable to us, including, without limitation, tender of shares of our
common stock then owned by the optionee. Each grant of an option under the
Primus-TresCom Option has been evidenced by an option agreement which sets
forth the number of shares of our common stock subject to the option and
includes other terms and conditions applicable to the option. These options are
not assignable or transferable except by will or by the laws of descent and
distribution, and, during the lifetime of the optionee, the option may be
exercised only by the optionee.

   The tax consequences to Primus and the recipient of these options upon the
grant and exercise of either a NQSO or ISO, and the sale of our common stock
acquired upon exercise thereof, are identical to those described for NQSOs and
ISOs under "--Employee Stock Option Plan" above.

   Director Stock Option Plan. We also established a Director Stock Option Plan
on July 27, 1995, as amended. The purpose of the Director Stock Option Plan is
to encourage ownership in Primus by outside directors (present or future
incumbent directors who are not affiliated with or employees Primus or any

                                       87
<PAGE>

subsidiary and who have not been nominated to serve as directors pursuant to an
agreement with Primus) whose services are considered essential to our continued
progress. Options granted under the Director Stock Option Plan are NQSOs. The
Director Stock Option Plan is administered by a committee of the board of
directors consisting of those directors who are not eligible to receive grants
thereunder. The total number of shares of our common stock for which options
may be granted pursuant to the Director Stock Option Plan is 338,100. On the
effective date of the Director Stock Option Plan or the first date thereafter
that any director becomes eligible to receive an award under the Director Stock
Option Plan, each eligible director will automatically receive an option to
purchase 15,000 shares of our common stock, exercisable for 5,000 shares
immediately, and 5,000 on each of the next two anniversary dates of the grant
date. All options become immediately exercisable, however, upon the retirement
of a director in accordance with any mandatory retirement policy of our board
of directors, upon the death or permanent disability of a director, or if we
merge with another company and we are not the surviving corporation, we enter
into an agreement to sell or otherwise dispose of all or substantially all of
our assets, or any person or group acquires more than 20% of our outstanding
voting stock.

   The option price is the fair market value at the date on which an option is
granted. Payment for the exercise of options may consist of cash or our common
stock. Options issued under the Director Stock Option Plan are not transferable
other than by will or the laws of descent and distribution. Options expire upon
the earlier of five years from the date they were granted or three years
following either the retirement or resignation of the director, the failure of
the director to be re-elected, or the permanent disability or death of the
director. No options may be granted under the Director Stock Option Plan after
December 31, 2005.

   The grant of a NQSO has no immediate tax consequences to Primus. Upon the
exercise of a NQSO by a director, we are entitled to a deduction in an amount
equal to the difference between the fair market value of the share acquired
through exercise of the NQSO and the exercise price of the NQSO. There are no
tax consequences to Primus if a NQSO lapses before exercise or is forfeited.

   The tax consequences to a director upon the grant and exercise of a NQSO,
and the sale of our common stock acquired upon exercise thereof, are identical
to those described for NQSOs under "--Employee Stock Option Plan" above, except
that we have no withholding obligations upon the exercise of a NQSO by a
director.

   Employee Stock Purchase Plan. During 1997, our board of directors adopted
and the stockholders approved an Employee Stock Purchase Plan. The Employee
Stock Purchase Plan provides employees with the right to purchase shares of our
common stock through payroll deduction. A total of 2,000,000 shares of our
common stock are available for purchase under the Employee Stock Purchase Plan,
subject to adjustment in the number and price of shares of our common stock
available for purchase in the event the outstanding shares of our common stock
are increased or decreased through stock dividends, recapitalizations,
reorganizations or similar changes. This ESP Plan is to be administered by our
board of directors, which may delegate responsibility for such administration
to a committee of our board of directors. Subject to the terms of this ESP
Plan, our board of directors or the committee shall have authority to interpret
the ESP Plan, to prescribe, amend and rescind rules and regulations relating to
it, and to make all other determinations deemed necessary or advisable in
administering the ESP Plan.

   An employee of a participating company is eligible to participate in the ESP
Plan if the employee, as of the last day of the month immediately preceding the
effective date of an election to purchase shares of our common stock pursuant
to the ESP Plan (1) has been employed on a full-time basis for at least six
consecutive months; or (2) has been employed on a part-time basis for at least
24 consecutive months.

   Presently, only our employees residing in the United States are eligible to
participate in the ESP Plan. An employee is considered to be a part-time
employee if the employee is scheduled to work at least 20 hours per week.
Notwithstanding the foregoing, any employee who, after purchasing our common
stock under the ESP Plan, would own five percent or more of the total combined
voting power or value of all classes of our stock or

                                       88
<PAGE>

any parent corporation or subsidiary corporation thereof is not eligible to
participate. Ownership of stock is determined in accordance with the provisions
of Section 424(d) of the Internal Revenue Code. Further, an employee is not
eligible to participate if such participation would permit such employee's
rights to purchase stock under all employee stock purchase plans of the
participating companies which meet the requirements of section 423(b) of the
Code to accrue at a rate which exceeds $25,000 in fair market value (as
determined pursuant to section 423(b)(8) of the Code) for each calendar year in
which such option is outstanding.

   Eligible employees may elect to participate in the Employee Stock Purchase
Plan during an offering which starts on the first day of each month beginning
on or after adoption of the Employee Stock Purchase Plan by our board of
directors and ends on the last day of each month. Shares will be deemed to have
been purchased on the last day of such month. The purchase price per share
offered under the Employee Stock Purchase Plan will be 85 percent of the lesser
of: (1) the fair market value per share on the first day of the month, or if
such date is not a trading day, then on the next trading day thereafter; or (2)
the fair market value per share on the last day of the month, or if such date
is not a trading day, then on the next trading day thereafter.

   An eligible employee who wishes to participate in the Employee Stock
Purchase Plan shall file an election form with our board of directors or the
committee governing the ESP Plan at least 15 days before the first of the month
for the first offering for which such election form is effective. On this form
an employee may elect to have payroll deductions made from his compensation on
each regular payday during the time he is a participant in the ESP Plan. All
payroll deductions shall be credited to the participant's account under the ESP
Plan. A participant who is on an approved leave of absence may authorize
continuing payroll deductions.

   If the total number of shares of our common stock for which purchase rights
are exercised on the last day of a month exceeds the maximum number of shares
of our common stock available, our board of directors or the relevant committee
shall make a pro rata allocation of shares available for delivery and
distribution in as nearly a uniform manner as practicable, and as it shall
determine to be fair and equitable, and the unapplied account balances shall be
returned to participants as soon as practicable following the last day of the
month.

   A participant may discontinue his participation in the ESP Plan at any time,
but no other change can be made during an offering, including, but not limited
to, changes in the amount of payroll deductions for such offering. A
participant may change the amount of payroll deductions for subsequent
offerings by giving written notice of such change to our board of directors or
the relevant committee on or before the 15th day of the month immediately
preceding the first of the month for which such change is effective.

   A participant may elect to withdraw the balance credited to the
participant's account by providing a termination form to our board of directors
or the committee at any time before the last day of the month applicable to any
offering. A participant may withdraw all, but not less than all, of the amounts
credited to the participant's account. All amounts credited to such
participant's account shall be paid as soon as practicable following the
committee's receipt of the participant's termination form, and no further
payroll deductions will be made with respect to the participant. A participant
who elects to withdraw from an offering shall be deemed to have elected not to
participate in each of the four succeeding offerings following the date on
which the participant gives a termination form to the committee.

   Upon termination of a participant's employment for any reason other than
death, including termination due to disability or continuation of a leave of
absence beyond 90 days, all amounts credited to such participant's account
shall be returned to the participant. In the event of a participant's (1)
termination of employment due to death or (2) death after termination of
employment but before the participant's account has been returned, all amounts
credited to such participant's account shall be returned to the participant's
successor-in-interest. A participant who is on an approved leave of absence
shall remain eligible to participate in the ESP Plan until the end of the first
offering ending after commencement of such approved leave of absence. A
participant who has been on an approved leave of absence for more than 90 days
shall not be eligible to participate in any offering that begins on or after
the commencement of such approved leave of absence so long as such leave of
absence continues.

   All funds held or received by us under the ESP Plan may be used for any
corporate purpose until applied to the purchase of shares of our common stock
or refunded to employees and shall not be segregated from our general assets.
Shares of our common stock purchased under the ESP Plan will be issued from our
treasury stock or from our authorized but unissued shares. The participating
companies shall pay all fees and expenses incurred (excluding individual
Federal, state, local or other taxes) in connection with the ESP Plan.

   An Employee's rights under the ESP Plan belong to the employee alone and may
not be transferred or assigned to any other person during the employee's
lifetime. After the shares of our common stock have been issued under the ESP
Plan, such shares may be assigned or transferred the same as any other shares.

   The ESP Plan is not qualified under Section 401(a) of the Internal Revenue
Code. We generally will not be entitled to a deduction with respect to stock
purchased under the ESP Plan, unless the stock is disposed of less than one
year after our common stock is purchased by the employee, or less than two
years after each commencement of an offering.

   Generally, no tax consequences arise at the time the participant purchases
shares of our common stock. If a participant does not dispose of shares of our
common stock purchased under the ESP Plan for at least one year after the date
of purchase and at least two years after the grant of the purchase right, he
will be deemed to have received compensation taxable as ordinary income for the
taxable year in which the disposition occurs in an amount equal to the lesser
of (a) the 15% discount originally allowed, or (b) the excess over the purchase
price of (i) the amount actually received for the shares if sold or exchanged
or (ii) the fair market value of the shares on the date of any other
termination of his ownership (such as by gift). The amount of such ordinary
income is then added to the participant's basis in his shares for purposes of
determining capital gain or loss.

   If a participant disposes of shares of our common stock purchased under the
ESP Plan less than one year after the date of purchase, or more than one year
after the date of purchase but within two years after the grant of the purchase
right, he will be deemed to have received compensation taxable as ordinary
income in the amount of the difference between the amount paid for the shares
and the value of the shares at the time of purchase. If the shares are sold or
exchanged, the amount of such ordinary income is added to the participant's
basis in his shares for purposes of determining capital gain or loss. If a
participant dies before disposing of the shares purchased under the ESP Plan,
he will be deemed to have realized compensation income taxable as ordinary
income in the taxable year closing with his death in an amount equal to the
lesser of clauses (a) and (b)(ii) as set forth in the immediately preceding
paragraph. He is deemed not to have realized any capital gain or loss because
of death.

   Our board of directors or the relevant committee shall have the right to
amend, modify or terminate the ESP Plan at any time without notice, provided
that no employee's then existing rights are adversely affected without his or
her consent, and provided further, that upon any amendment of the ESP Plan,
stockholder approval will be obtained if required by law.

   Restricted Stock Plan. We established the 1998 Restricted Stock Plan on
December 15, 1998 to facilitate the grant of "restricted stock" to selected
individuals who contribute to our development and success and that of our
subsidiaries. The total number of shares of our common stock which may be
granted under the 1998 Restricted Stock Plan is 750,000. For any calendar year,
the maximum number of shares of our common stock which may be granted to any
individual is 200,000.

   The 1998 Restricted Stock Plan is administered by our board of directors,
provided that our board of directors may delegate its authority under the 1998
Restricted Stock Plan to a member of our board of directors, a committee of our
board of directors or an executive officer of Primus. Except as otherwise
provided by our board of directors, only our board of directors or the relevant
committee may make grants under the 1998 Restricted Stock Plan to an executive
officer or establish the number of shares of our common stock that can be
subject to grants for any of our fiscal periods.


                                       90
<PAGE>

   Persons who may receive grants under the 1998 Restricted Stock Plan are
limited to our and our subsidiaries' employees, consultants, agents, advisers,
managers or any other individual whose participation in the 1998 Restricted
Stock Plan is determined by our board of directors to be in our best interests.
However, notwithstanding the foregoing, individuals who are required to file
reports under Section 16(a) of the Exchange Act are not eligible to receive
grants under the 1998 Restricted Stock Plan.

   Unless delegated to the relevant committee, our board of directors has the
full and final authority to:

     (i) designate recipients of grants,

     (ii) determine the types of grants to be made

     (iii) determine the number of shares of our common stock to be subject
  to a grant,

     (iv) establish the terms and conditions of each grant, including, but
  not limited to, the nature and duration of any restriction or condition,

     (v) prescribe the form of each award agreement pursuant to which grants
  are made,

     (vi) make grants alone, in addition to, in tandem with or in
  substitution or exchange for any other grant or any other award granted
  under another plan maintained by Primus or a subsidiary, and

     (vii) amend, modify or supplement the terms of any outstanding grant of
  shares of our common stock under the 1998 Restricted Stock Plan.

   The Board or its delegate will establish a restricted period with respect to
each grant of restricted stock under the 1998 Restricted Stock Plan. Except as
otherwise determined by our board of directors, the minimum restricted period
is one year. Each grant may be subject to a different restricted period, and
may be subject to restrictions other than or in addition to the expiration of
time, such as the satisfaction of individual or corporate objectives.
Performance objectives other than the lapse of time must be established on or
before the 90th day of the period of service to which the objectives relate and
while the outcome is substantially uncertain, and may include:

  .  earnings per share,

  .  total stockholder return,

  .  operating earnings,

  .  growth in assets,

  .  return on equity,

  .  return on capital,

  .  market share,

  .  stock price,

  .  net income,

  .  cash flow,

  .  sales growth in general,

  .  sales growth by type of product,

  .  sales growth by type of customer,

  .  retained earnings,

  .  completion of acquisitions,

  .  completion of divestitures and asset sales,

  .  cost or expense reductions,

  .  introduction or conversion of products or services, and

  .  achievement of specified management information systems objectives.

                                       91
<PAGE>

   In addition, performance objectives may include positive results,
maintaining the status quo or limiting economic losses.

   Our common stock subject to grants under the 1998 Restricted Stock Plan may
not be sold, transferred, assigned, pledged or otherwise encumbered or disposed
of during the restricted period. These restrictions lapse upon the expiration
of the restricted period, whether by lapse of time or the fulfillment of
applicable performance objectives. Unless our board of directors provides
otherwise in any particular award agreement, recipients may vote the shares
subject to that award agreement and will be entitled to receive dividends paid
with respect to such shares. However, our board of directors may require that
such dividends be reinvested in shares of our common stock, which shares may or
may not be subject to the same restrictions as the shares subject to the award
agreement.

   Unless otherwise provided by our board of directors, if a recipient
terminates employment or engagement for any reason other than death or
disability, any shares of our common stock held by such recipient that remain
subject to restrictions under the 1998 Restricted Stock Plan will be forfeited.
Unless otherwise provided by our board of directors, if a recipient terminates
employment or engagement by reason of death or disability, all restrictions
under the 1998 Restricted Stock Plan applicable to shares held by such
recipient will lapse. For purposes of the 1998 Restricted Stock Plan,
"disability" means "total and permanent disability," as described in Section
22(e)(3) of the Code.

   The numbers of and type of shares subject to the 1998 Restricted Stock Plan
and to grants made thereunder will be adjusted to the extent necessary to
prevent the enlargement or diminution of rights in the event of any merger,
reorganization, consolidation, recapitalization, stock dividend, spin-off or
other change in corporate structure affecting our common stock.

   All restrictions on shares of our common stock granted under the 1998
Restricted Stock Plan will lapse and the 1998 Restricted Stock Plan will
terminate in the event of certain major corporate events. Those events include:
(i) dissolution or liquidation of the Company, (ii) merger, consolidation or
reorganization of the Company in which the Company is not the surviving entity,
or (iii) any transaction approved by our board of directors that results in any
person(s) or entity(ies) owning 80% or more of the combined voting power of all
classes of securities of Primus. Notwithstanding the foregoing, the lapse of
restrictions and the termination of the 1998 Restricted Stock Plan described in
this paragraph will not occur despite the consummation of such a major
corporate transaction if: (x) provision is made for continuation of the 1998
Restricted Stock Plan following such transaction, or for the substitution for
such shares of new restricted stock of a successor entity (with appropriate
adjustments as to the number and kind of shares), or (y) a majority of our
board of directors determines that such transaction should not trigger the
lapse of the restrictions and the termination of the 1998 Restricted Stock
Plan.

   Under the Internal Revenue Code, if property is transferred in connection
with the performance of services, the excess, if any, of the fair market value
of the property received over the price paid for such property is included in
the income of the person performing such services as ordinary income. The
income is included at the time such property either ceases to be subject to a
substantial risk of forfeiture or is transferable free of such risk of
forfeiture. The fair market value of such property is generally measured at the
time when the substantial risk of forfeiture lapses, or when the property
becomes transferable free of such risk of forfeiture, unless an election is
made, as described below, to include the amount of any income at an earlier
date.

   Shares of our common stock granted to a recipient under the 1998 Restricted
Stock Plan will be treated as acquired in connection with the performance of
services and will be considered to be subject to a substantial risk of
forfeiture during the restricted period, as described above. A recipient who
receives a grant of restricted stock will recognize ordinary compensation
income, in each year in which the restricted period lapses, equal to the fair
market value of the shares of our common stock as to which the restricted
period lapses. The fair market value of such shares at the time of vesting
generally will be equal to the then current market price of

                                       92
<PAGE>

such shares. A recipient's basis for determining gain or loss on a subsequent
disposition of such shares of our common stock will be the amount which he must
include in income when the shares vest. Any gain or loss recognized on a
disposition of such shares generally will be long-term capital gain or loss if
the recipient holds the shares for more than one year from the date the
restricted period lapses.

   The general rules described above do not apply if a recipient elects,
pursuant to Section 83(b) of the Internal Revenue Code, to include in his
income the fair market value of the shares of our common stock subject to an
award at the time the shares are awarded, without taking into account the
effect of the restrictions on the shares. If a recipient makes such a Section
83(b) election, he will not be required to recognize any income in any later
year in which the shares vest. The recipient's basis for determining gain or
loss on a disposition of the shares will be the amount included in income in
the year of the initial award. Any gain or loss recognized by the recipient on
a disposition of shares which were the subject of a Section 83(b) election will
be capital gain or loss, and will be long-term capital gain or loss if the
recipient holds the shares for more than one year from the date the shares are
transferred to him. If, however, the recipient forfeits any shares upon a
termination of employment, he will not be entitled to deduct any loss upon such
forfeiture even though he may have been required to include an amount in income
by virtue of a Section 83(b) election.

   In general, for federal income tax purposes, we will be entitled to a
deduction in the same amount and at the same time as a recipient recognizes
income. In certain circumstances, our deductions may be limited because of the
application of the $1,000,000 compensation cap under Section 162(m) of the
Internal Revenue Code.

Employment Agreements

   K. Paul Singh. We have entered into an employment agreement with Mr. Singh.
The Singh Agreement is a five-year contract, with a term beginning on June 1,
1994 and continuing until May 30, 1999, and from year to year thereafter unless
terminated. On May 30, 1999, this agreement renewed by its own terms for an
additional year. Under the terms of the Singh Agreement, Mr. Singh is required
to devote his full time efforts to Primus as Chairman of our board of
directors, President and Chief Executive Officer. We are required to compensate
Mr. Singh at an annual rate of $250,000 effective January 1, 1997 (which amount
is reviewed annually by our board of directors and is subject to increase at
their discretion). Mr. Singh, however, agreed to defer payment of his base
salary from June 1, 1994 through May 31, 1995, which was subsequently paid to
him on July 31, 1996. We are also obligated to:

     (i) allow Mr. Singh to participate in any bonus or incentive
  compensation plan approved for senior management,

     (ii) provide life insurance in an amount equal to three times Mr.
  Singh's base salary and disability insurance which provides monthly
  payments in an amount equal to one-twelfth of his then applicable base
  salary,

     (iii) provide medical insurance, and

     (iv) pay up to $2,500 annually for Mr. Singh's personal tax and
  financial planning services.

   We may terminate the Singh Agreement at any time in the event of Mr. Singh's
disability or for cause, each as defined in the Singh Agreement. Mr. Singh may
resign at any time without penalty (other than the non-competition obligations
discussed below). If we terminate the Singh Agreement for disability or cause,
we will have no further obligations to Mr. Singh. If, however, we terminate the
Singh Agreement other than for disability or cause, we must pay Mr. Singh one-
twelfth of his then applicable base salary as severance pay. If Mr. Singh
resigns, he may not directly or indirectly compete with our business until six
months after his resignation. If we terminate Mr. Singh's employment for any
reason, Mr. Singh may not directly or indirectly compete with our business
until six months after the final payment of any amounts owed to him under the
Singh Agreement become due.

   Wesley T. O'Brien. TresCom entered into an employment agreement with Mr.
Wesley T. O'Brien which was amended and restated on February 15, 1997 and was
further amended on February 3, 1998. The O'Brien Agreement provided for Mr.
O'Brien to serve as TresCom's President and Chief Executive Officer for which
he would receive an annual base salary of $231,000 and was to terminate in June
1999; however, it was terminated as of June 22, 1998. Pursuant to the terms of
the O'Brien Agreement, Mr. O'Brien was to receive any unpaid salary and bonus,
as well as an additional amount equal to the salary remaining until June 1999.
In addition, Mr. O'Brien agreed to a customary confidentiality clause and to a
non-competition clause which prohibits Mr. O'Brien from competing with TresCom
for one year from the date of the termination of the O'Brien Agreement. The
consummation of the TresCom merger constituted a Change in Control as defined
in the O'Brien Agreement, making Mr. O'Brien eligible for a one-time special
bonus of $1.5 million. The first installment of this special bonus was paid
contemporaneously with the closing of the TresCom merger and the remainder was
paid upon Mr. O'Brien's termination.

   Other Agreements. TresCom also entered into agreements with Mr. Dan O'Connor
and Ms. Denise Boerger. The O'Connor/Boerger Agreements each provide for a one-
time special bonus of $500,000 in the event of a change in control, which was
triggered by the TresCom merger. The first installment of these bonuses was
paid contemporaneously with the closing of the TresCom merger. The second and
third installments are due on the first and second anniversary, respectively,
of the change in control so long as Mr. O'Connor or Ms. Boerger, as the case
may be, remains employed by Primus.

                    TRANSACTIONS WITH AFFILIATES AND OTHERS

Private Equity Sale

   In July 1996, we completed the sale of 965,999 shares of our common stock
for an aggregate purchase price of approximately $8.0 million to:

     (i) Quantum Industrial Partners LDC, the principal operating subsidiary
  of Quantum Industrial Holdings Ltd., an investment fund advised by Soros
  Fund Management, a private investment firm owned by Mr. George Soros,

     (ii) Winston Partners II LDC, the principal operating subsidiary of
  Winston Partners II Offshore Ltd., an investment fund advised by Chatterjee
  Management Company, a private entity owned by Dr. Purnendu Chatterjee,

     (iii) Winston Partners II LLC, an investment fund advised by Chatterjee
  Management Company, and

     (iv) S-C Phoenix Holdings, L.L.C., an investment vehicle owned by
  affiliates of Mr. Soros and Dr. Chatterjee

   The Soros/Chatterjee Group named above also purchased, for an additional
$8.0 million, warrants representing the right to receive, upon exercise, an
indeterminate number of shares of our common stock with a fair market value of
$10.0 million as of the date of exercise, plus up to 627,899 additional shares
of our common stock. The warrants have been exercised in full.

   The Soros/Chatterjee Group was granted registration rights pursuant to a
registration rights agreement with us. Under the registration rights
agreement, the Soros/Chatterjee Group is entitled to demand registration of
its shares after July 31, 1998, a maximum of three times, the third demand
being available only if the Soros/Chatterjee Group has not registered 80% of
its shares of our common stock after the first demand registration. We are not
required to effect any demand registration within 180 days after the effective
date of a previous demand registration and may postpone, on one occasion in
any 365-day period, the filing or effectiveness of a registration statement
for a demand registration for up to 120 days under certain circumstances,
including pending material transactions or the filing of a registration
statement relating to the sale of shares for our own account. The
Soros/Chatterjee Group is also entitled to unlimited piggyback registrations.
All such registrations would be at our expense, exclusive of underwriting
discounts and commissions, and legal fees (up to $25,000 for each such
offering) incurred by the holders of the registrable securities. We and the
Soros/Chatterjee Group have entered into customary indemnification and
contribution provisions.

   Additionally, members of the Soros/Chatterjee Group are entitled to tag-
along rights to participate with Mr. Singh and members of his family in sales
of capital stock on the same terms and conditions as Mr. Singh and members of
his family. The Soros/Chatterjee Group shares are also subject to drag-along
rights in the event holders of a majority of our common stock decide to sell
80% or more of the outstanding capital stock of Primus. A securityholders
agreement provides that members of the Soros/Chatterjee Group will not
transfer shares of our common stock to a company, or any affiliate, that
competes with us to a material extent in the provision of telecommunications
services in the United States, Australia, the United Kingdom, France, Germany,
Mexico, Canada, Italy or Hong Kong.

Teleglobe

   We entered into an agreement on January 12, 1996 with Teleglobe, pursuant
to which Teleglobe purchased 410,808 shares of our common stock for a total of
$1,458,060. The equity investment was consummated in February 1996 as was a
loan by Teleglobe of $2.0 million to us. The loan was repaid in full with the
proceeds from the offering of the 1997 senior notes. Related to the Teleglobe
investments, we and a number of our subsidiaries have entered into trading
agreements with Teleglobe with respect to our respective

                                      95
<PAGE>

service offerings. The parties have also agreed to cooperate in an effort to
maximize efficiencies with respect to network facilities.

NSI Private Placements

   In 1995 and 1996, we engaged Northeast Securities, Inc. to serve as the
placement agent for two private placements of our common stock. Mr. Andrew B.
Krieger, a former director of Primus, served as a broker-dealer in the private
placements through an affiliation with Northeast Securities. In connection with
these offerings, we paid Mr. Krieger cash commissions aggregating approximately
$1,007,000. We also retained Krieger Associates, of which Mr. Krieger is the
President and Chief Executive Officer, to perform certain financial and other
consulting services and paid a total of approximately $105,828 for the
performance of such services during 1995 and 1996. In addition, in connection
with these private placements, we issued a total of 193,718 shares of our
common stock to Krieger Associates and Mr. Krieger, and at the direction of Mr.
Krieger issued a total of 74,003 shares of our common stock to other
individuals associated with the transaction. We also issued, in connection with
these private placements, a total of 245,555 shares of our common stock to
Northeast Securities and certain of its employees associated with the
transactions.

Hotkey Investment

   In March 1998, we invested in Hotkey, a Melbourne, Australia-based Internet
service provider, acquiring a 60% interest in the Company. Mr. Singh was the
holder of approximately 14% of the outstanding equity securities of Hotkey. We
purchased our 60% ownership of Hotkey for approximately $1.3 million in cash.
In February 1999, we purchased the remaining 40% of Hotkey from its
stockholders for approximately $1.1 million comprised of $0.3 million in cash
and 57,025 shares of our common stock. In connection with the February 1999
transaction, K. Paul Singh received 6,148 shares of our common stock and
$34,252 in cash.

Executive Officer Loan

   As of September 3, 1998, we loaned Ravi and Madhu Bhatia the principal
amount of $164,000. As of March 31, 1999, the Bhatias paid down the principal
amount of the loan to $112,681 and we extended the maturity of the loan. The
loan is now due on the earlier of the termination of Mr. Bhatia's employment or
August 31, 1999. Interest is calculated daily at a rate of 10% per annum.
Repayment of the loan is secured by options to purchase our common stock held
by Mr. Bhatia and a pledge of 50,000 shares of our common stock. The common
stock which is pledged is subject to a prior pledge in favor of Schroder & Co.
to secure payment of certain loans.

TresCom Merger

   In June 1998, pursuant to an Agreement and Plan of Merger dated February 3,
1998, as amended, Taurus Acquisition Corporation, a Florida corporation and our
wholly-owned subsidiary, merged with and into TresCom International, Inc., a
Florida corporation. Under the terms of the merger agreement, TresCom
shareholders received 0.6147 shares of our common stock in exchange for each
share of TresCom's common stock outstanding at the effective time of the
merger, other than shares beneficially owned by us or our affiliates. The
exchange ratio was determined pursuant to the merger agreement by dividing
$12.00 by $19.5223, which was the weighted average sales price of our common
stock during the 20-trading day period ending on June 4, 1998. As a result of
the consummation of the merger, TresCom became our wholly-owed subsidiary.

   As a result of the merger, Warburg, Pincus Investors, L.P., which
beneficially owned approximately 52% of TresCom's common stock, received
approximately 3,875,689 shares of our common stock valued at approximately
$71,458,016. Warburg, Pincus currently beneficially owns approximately 13.5% of
our common stock. Pursuant to a Stockholder Agreement dated February 3, 1998,
by and among Mr. Singh, Warburg, Pincus, and us, Warburg, Pincus was granted
certain demand and piggyback registration rights related to shares

                                       96
<PAGE>

of our common stock, which if exercised, would permit Warburg, Pincus to
transfer such shares free of Rule 144 volume limitations (the same as non-
affiliates of TresCom), and the right, so long as Warburg, Pincus beneficially
owns 10% or more of our common stock, to nominate an individual, reasonably
acceptable to our non-employee directors, to serve as a director on our Board
of Directors.

Satellite Earth Station

   In June 1998, our U.K. subsidiary entered into a $2.1 million agreement for
the design, manufacture, installation and the provision of training with
respect to a satellite earth station in London. David Hershberg, one of our
directors, is the chairman, president and a stockholder of the company
providing such services. During 1998, $1.2 million was paid by us for the above
services.

     stock subject to options or warrants currently exercisable or which become
     exercisable on or prior to 60 days from July 15, 1999 are deemed
     outstanding for computing the percentage ownership of the person holding
     such options or warrants, but are not deemed outstanding for computing the
     percentage ownership of any other person.

 (2) Based upon 28,707,691 shares of our common stock outstanding as of July
     29, 1999.

Stockholders' Rights Plan

   We have adopted a stockholders' rights plan in which we granted preferred
stock purchase rights as a dividend to our stockholders of record at the close
of business on December 31, 1998. In implementing this plan, our Board has
declared a distribution of one right for each outstanding share of our common
stock. Each right entitles the holder to purchase from us 1/1000 of a share of
Series B Junior participating Preferred Stock at a purchase price of $90 per
1/1000 of a share of Series B Preferred Stock, subject to adjustment. Each
1/1000 of a share of Series B 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 we redeem them.

   The rights are not exercisable and not 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 our then outstanding common
stock or announces an offer to acquire 20% or more of our then outstanding
common stock.

   If

   (i)  we are the surviving corporation in a merger with an acquiring person
       and shares of our common stock remain outstanding,

  (ii)  a person becomes the beneficial owner of 20% or more of our then
        outstanding common stock,

  (iii) an acquiring person engages in one or more "self- dealing"
        transactions as set forth in the rights plan, or

  (iv) when there is an acquiring person, the acquiring person's ownership
       interest is increased by more than 1% (for example 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, Series B Preferred Stock
(or, in certain circumstances, common stock, cash, property or other Primus
securities) having a current market value equal to two times the exercise price
of the right.

   If

  (i) we are acquired in a merger or other business combination transaction
      and we are not the surviving corporation (other than a merger described
      in the preceding paragraph),

  (ii) any person consolidates or merges with us and all or part of our
       common stock is converted or exchanged for securities, cash or
       property of any other person, or

  (iii) 50% or more of our assets or earning power is sold or transferred,

each holder of a right (other than those held by an acquiring person) shall
therefore 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.

   Our board of directors may redeem the rights in whole, but not in part, at a
price of $0.001 per right (subject to adjustment in certain events), payable,
at the election of the board of directors, in cash or shares of common stock.
When the board of directors orders 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.

                       DESCRIPTION OF OTHER INDEBTEDNESS

1997 Senior Notes

   General. Our 1997 senior notes are senior obligations, limited to $225
million in principal amount, which mature on August 1, 2004. The 1997 senior
notes, which were issued pursuant to the 1997 indenture, accrue interest at a
rate of 11 3/4% per annum. Interest is payable each February 1 and August 1,
commencing on February 1, 1998.

   Ranking. The 1997 senior notes will rank senior in right of payment to any
of our future subordinated indebtedness (as defined in the 1997 indenture), and
pari passu in right of payment with all of our senior indebtedness. Because we
operate via a holding company that conducts its business through its
subsidiaries, all existing and future indebtedness and other liabilities and
commitments of our subsidiaries, including trade payables, will be structurally
senior to the 1997 senior notes.

   Security. The indenture required us to purchase and pledge to First Union
National Bank, as security for the benefit of the holders of the 1997 senior
notes, securities consisting of U.S. government securities in an amount
sufficient to provide for the payment in full of the first six scheduled
interest payments due on the 1997 senior notes. We used approximately $71.8
million of the net proceeds of the 1997 senior notes to acquire these pledged
securities. Assuming the first six scheduled interest payments on the 1997
senior notes are made in a timely manner, all remaining pledged securities will
be released.

   Optional Redemption. The 1997 senior notes are not redeemable prior to
August 1, 2001. Thereafter, the 1997 senior notes will be redeemable, in whole
or in part, at our option, at the redemption prices set forth in the indenture,
plus accrued and unpaid interest to the applicable redemption date.
Specifically, if redeemed during the 12-month period commencing on August 1 of
the years set forth below, the redemption price will be that amount, expressed
as a percentage of the principal amount of the 1997 senior notes, set forth
below:

<TABLE>

                                                                      Redemption
   Year                                                                 Price

   <S>                                                                <C>
   2001..............................................................  105.875%
   2002..............................................................  102.938%
   2003 (and thereafter).............................................  100.000%
</TABLE>

   In addition, prior to August 1, 2000, we may redeem up to 35% of the
originally issued principal amount of the 1997 senior notes at 111.750% of the
principal amount thereof, plus accrued and unpaid interest through the
redemption date, with the net cash proceeds of one or more Public Equity
Offerings (as defined in the 1997 indenture); provided, however, that at least
65% of the originally issued principal amount of the 1997 senior notes remains
outstanding after the occurrence of such redemption.

   Change of Control. Upon the occurrence of a Change of Control (as defined in
the 1997 indenture), each holder of 1997 senior notes will have the right to
require us to repurchase all or any part of such holder's 1997 senior notes at
a purchase price in cash equal to 101% of the principal amount thereof, plus
accrued and unpaid interest to the date of purchase.

   Covenants. The 1997 indenture contains certain covenants that, among other
things, limit our ability and that of our Restricted Subsidiaries (as defined
in the 1997 indenture) to:

  .  incur additional indebtedness and issue preferred stock;

  .  pay dividends or make other distributions;

  .  repurchase Capital Stock (as defined in the 1997 indenture) or
     subordinated indebtedness or make certain other Restricted Payments (as
     defined in the 1997 indenture);

  .  create certain liens;


                                      101
<PAGE>


  .  enter into certain transactions with affiliates;

  .  sell assets;

  .  issue or sell Capital Stock of our Restricted Subsidiaries; or

  .  enter into certain mergers and consolidations.

   Pursuant to a consent solicitation, we amended the 1997 indenture to
generally conform portions of covenants relating to debt incurrence, restricted
payments, permitted investments and permitted liens to the corresponding
provisions in the 1998 indenture and to the corresponding provisions which will
be contained in the indenture.

   Events of Default. The 1997 indenture contains customary events of default,
including:

     (i) defaults in the payment of principal, premium or interest,

     (ii) defaults in the compliance with covenants contained in the 1997
  indenture,

     (iii) cross defaults on more than $5 million of other indebtedness,

     (iv) failure to pay more than $5 million of judgments that have not been
  stayed by appeal or otherwise and

     (v) the bankruptcy of Primus or certain of its subsidiaries.

1998 Senior Notes

   General. Our 1998 senior notes are senior obligations, limited to $150
million in principal amount, which mature on May 15, 2008. The 1998 senior
notes, which were issued pursuant to an indenture dated May 19, 1998, accrue
interest at a rate of 9 7/8% per annum. Interest is payable each May 15 and
November 15, commencing on November 15, 1998.

   Ranking. The 1998 senior notes rank senior in right of payment to any future
subordinated Indebtedness (as defined in the 1998 indenture governing the 1998
senior notes), and pari passu in right of payment with all senior indebtedness.
Because we are a holding company that conducts business through subsidiaries,
all existing and future indebtedness and other liabilities and commitments of
our subsidiaries, including trade payables, will be structurally senior to the
1998 senior notes.

   Optional Redemption. The 1998 senior notes are not redeemable prior to May
15, 2003. Thereafter, the 1998 senior notes will be redeemable, in whole or in
part, at our option, at the redemption prices set forth in the indenture, plus
accrued and unpaid interest to the applicable redemption date. Specifically, if
redeemed during the 12-month period commencing on May 15 of the years set forth
below, the redemption price will be that amount, expressed as a percentage of
the principal amount of the 1998 senior notes, set forth below:

<TABLE>

                                                                      Redemption
     Year                                                               Price
     ----                                                             ----------
     <S>                                                              <C>
     2003............................................................  104.938%
     2004............................................................  103.208%
     2005............................................................  101.604%
     2006 (and thereafter)...........................................  100.000%
</TABLE>

   In addition, prior to May 15, 2001, we may redeem up to 25% of the
originally issued principal amount of the 1998 senior notes at 109.875% of the
principal amount thereof, plus accrued and unpaid interest through the
redemption date, with the net cash proceeds of one or more Public Equity
Offerings (as defined in the 1998 indenture); provided, however, that at least
75% of the originally issued principal amount of the 1998 senior notes remains
outstanding after the occurrence of such redemption.


                                      102
<PAGE>

   Change of Control. Upon the occurrence of a Change of Control (as defined in
the 1998 indenture), each holder of 1998 senior notes will have the right to
require us to repurchase all or any part of such holder's 1998 senior notes at
a purchase price in cash equal to 101% of the principal amount thereof, plus
accrued and unpaid interest to the date of purchase.

   Covenants. The 1998 indenture contains certain covenants that, among other
things, limit the ability of Primus and its Restricted Subsidiaries (as defined
in the 1998 indenture) to:

  .  incur additional indebtedness and issue preferred stock,

  .  pay dividends or make other distributions,

  .  repurchase Capital Stock (as defined in the 1998 indenture) or
     subordinated indebtedness or make certain other Restricted Payments (as
     defined in the 1998 indenture),

  .  create certain liens,

  .  enter into certain transactions with affiliates,

  .  sell assets,

  .  issue or sell Capital Stock of our Restricted Subsidiaries, or

  .  enter into certain mergers and consolidations.

   These covenants are substantially the same as those contained in the
indenture. See "Description of Exchange Notes--Covenants."

   Events of Default. The 1998 indenture contains customary events of default,
including:

     (i) defaults in the payment of principal, premium or interest,

     (ii) defaults in the compliance with covenants contained in the 1998
  indenture,

     (iii) cross defaults on more than $10 million of other indebtedness,

     (iv) failure to pay more than $10 million of judgments that have not
  been stayed by appeal or otherwise and

     (v) the bankruptcy of Primus or certain of its subsidiaries.

Telegroup Notes

   In June 1999, we issued $45.5 million aggregate principal amount of our 11
1/4% senior notes due 2009 to Telegroup, Inc. in a private placement. These
notes were issued pursuant to the same indenture as, and contain the same terms
as, our 11 1/4% senior notes due 2009 issued in January 1999. In connection
with our issuance of these notes to Telegroup, we agreed to register them for
resale by October 28, 1999. If we do not cause these notes to be registered by
October 28, 1999, additional cash interest will accrue on the Telegroup notes
as liquidated damages in an amount equal to .50% per annum of the principal
amount of the notes. The amount of liquidated damages will increase by an
additional .50% per annum of the principal amount of the notes with respect to
each subsequent 90 day period (or portion thereof) until the resale of the
Telegroup notes has been registered, up to a maximum rate of 1.5% per annum.
Immediately upon the registration of the Telegroup notes, there shall be no
further accrual of liquidated damages with respect to the Telegroup notes. For
a further description of the notes issued to Telegroup, see "Description of
Exchange Notes."

                         DESCRIPTION OF EXCHANGE NOTES

   Set forth below is a summary of certain provisions of the new notes. The new
notes will be issued pursuant to an indenture, dated as of January 29, 1999,
between us, as issuer, and First Union National Bank, as trustee. The following
summary of certain provisions of the Indenture does not purport to be complete
and is subject to, and is qualified in its entirety by reference to, all the
provisions of the indenture, including the definitions of certain terms therein
and those terms made a part thereof by the Trust Indenture Act. Whenever
particular Sections or defined terms of the indenture not otherwise defined
herein are referred to, such Sections or defined terms are incorporated herein
by reference. Copies of the form of the indenture are available upon request
from us or the trustee. The term "Note" or "Notes" includes the initial notes
and the new notes.

   The form and terms of the new notes will be identical in all material
respects to the form and terms of the initial notes, except that:

     (i) the new notes have been registered under the Securities Act and,
  therefore, will not bear legends restricting the transfer thereof,

     (ii) holders of the new notes, except in limited circumstances, will not
  be entitled to liquidated damages, and

     (iii) holders of the new notes will not be, and upon consummation of the
  exchange offer, holders of the initial notes will no longer be, entitled to
  certain rights under the Registration Rights Agreement intended for the
  holders of unregistered securities.

   The exchange offer shall be deemed consummated upon the occurrence of the
delivery by us to the Registrar under the exchange note indenture in the same
aggregate principal amount as the aggregate principal amount of Initial Notes
that are validly tendered by holders thereof pursuant to the exchange offer.

General

   The Notes issued on the Closing Date will be our senior obligations, limited
to $200 million aggregate principal amount, except that the indenture will
provide for the issuance of an additional $75 million of Notes which may be of
the same series as, and which may vote as a single class for purpose of the
Indenture with, the $200 million of Notes issued on the Closing Date (the
"Additional Notes"). In addition, the Notes have the following characteristics:

</TABLE>

Interest on the Notes will be payable to the Person in whose name the Note (or
any predecessor Note) is registered at the close of business on the preceding
January 1 or July 1 as the case may be. Interest will be computed on the basis
of a 360-day year of twelve 30-day months.

   Principal of, premium, if any, and interest on the Notes will be payable by
wire transfer of immediately available funds to the holder of the global note

Primus (which initially will be the corporate trust operations office of the
Trustee at NC 1153, 1125 West W.T. Harris Boulevard, Charlotte, North Carolina
28262); provided that, at our option, payment of interest may be made by check
mailed to the address of the holders as such address appears in the Note
Register.

   The Notes will be issued only in fully registered form, without coupons, in
denominations of $1,000 of principal amount at maturity and any integral
multiple thereof. No service charge will be made for any

registration of transfer or exchange of Notes, but we may require payment of a
sum sufficient to cover any transfer tax or other similar governmental charge
payable in connection therewith.

Optional Redemption

   The Notes will be redeemable, at our option, in whole or in part, at any
time or from time to time, on or after January 15, 2004 and prior to maturity,
upon not less than 30 nor more than 60 days' prior notice mailed by first class
mail to each holders' last address as it appears in the note register, at the
following redemption prices (expressed in percentages of principal amount
thereof), plus accrued and unpaid interest and liquidated damages, if any,
thereon to the redemption date (subject to the right of holders of record on
the relevant Regular Record Date to receive interest due on an interest payment
date that is on or prior to the Redemption Date), if redeemed during the 12-
month period commencing on January 15, of the years set forth below:

   2007 (and thereafter).............................................  100.000%
</TABLE>

   Notwithstanding the foregoing, prior to January 15, 2002 we may on any one
or more occasions redeem up to 35% of the originally issued principal amount of
Notes at a redemption price of 111.25% of the principal amount thereof, plus
accrued and unpaid interest and liquidated damages, if any, thereon to the
redemption date, with the Net Cash Proceeds of one or more Public Equity
Offerings; provided (i) that at least 65% of the originally issued principal
amount of Notes remains outstanding immediately after the occurrence of such
redemption and (ii) that notice of such redemption is mailed within 60 days of
the closing of each such Public Equity Offering. (Section 1101)

   In the case of any partial redemption, selection of the Notes for redemption
will be made by the trustee in compliance with the requirements of the
principal national securities exchange, if any, on which the Notes are listed
or, if the Notes are not listed on a national securities exchange, on a pro
rata basis, by lot or by such other method as the trustee in its sole
discretion shall deem to be fair and appropriate; provided that no Note of
$1,000 in principal amount at maturity or less shall be redeemed in part. If
any Note is to be redeemed in part only, the notice of redemption relating to
such Note shall state the portion of the principal amount thereof to be
redeemed. A new Note in principal amount equal to the unredeemed portion
thereof will be issued in the name of the holder thereof upon cancellation of
the original Note.

Ranking

   The indebtedness evidenced by the Notes will rank senior in right of payment
to any of our existing and future obligations that are expressly subordinated
in right of payment to the Notes and will rank pari passu in right of payment
with all other of our existing and future senior unsecured obligations,
including trade payables. As of March 31, 1999, after giving pro forma effect
to the offering of the new notes, and our issuance of $45.5 million of senior
notes due 2009 in connection with the Telegroup acquisition, we would have had
outstanding approximately $651.8 million of indebtedness on a consolidated
basis. Because we are a holding company that conducts our business through our
subsidiaries, all existing and future indebtedness and other liabilities and
commitments of our subsidiaries, including trade payables, will be structurally
senior to the notes. As of March 31, 1999, our consolidated subsidiaries had
outstanding aggregate liabilities of approximately $174.7 million, which
included $28.6 million of indebtedness.

Covenants

 Limitation on Indebtedness

   (a) We will not, and will not permit any of our Restricted Subsidiaries to,
Incur any Indebtedness (other than the Notes issued on the Closing Date);
provided, however, that we may Incur Indebtedness if immediately thereafter the
ratio of:

     (i) the aggregate principal amount (or accreted value, as the case may
  be) of Indebtedness of Primus and its Restricted Subsidiaries on a
  consolidated basis outstanding as of the Transaction Date to

     (ii) the Pro Forma Consolidated Cash Flow for the preceding two full
  fiscal quarters multiplied by two, determined on a pro forma basis as if
  any such Indebtedness that had been Incurred and the proceeds thereof had
  been applied at the beginning of such two fiscal quarters, would be greater
  than zero and less than 6.0 to 1.

   (b) Notwithstanding the foregoing, Primus and (except for Indebtedness under
subsections (v), (vii) and (xi) below) any Restricted Subsidiary may Incur each
and all of the following:

     (i) Indebtedness of Primus or any Restricted Subsidiary under one or
  more Credit Facilities in an aggregate principal amount at any one time
  outstanding not to exceed the greater of

       (a) $50 million or

       (b) 65% of Eligible Accounts Receivable, subject to any permanent
    reductions required by any other terms of the Indenture;

     (ii) Indebtedness (including Guarantees) Incurred by Primus or a
  Restricted Subsidiary after the Closing Date to finance the cost (including
  the cost of design, development, construction, acquisition, installation or
  integration) of equipment used in the telecommunications business or
  ownership rights with respect to indefeasible rights of use or minimum
  investment units (or similar ownership interests) in domestic or
  transnational fiber optic cable or other transmission facilities, in each
  case purchased or leased by Primus or a Restricted Subsidiary after the
  Closing Date (including acquisitions by way of Capitalized Leases and
  acquisitions of the Capital Stock of a Person that becomes a Restricted
  Subsidiary to the extent of the Fair Market Value (as determined in good
  faith by our board of directors, whose determination shall be conclusive
  and evidenced by a Board Resolution) of such equipment, ownership rights or
  minimum investment units so acquired);

     (iii) Indebtedness of any Restricted Subsidiary to Primus or
  Indebtedness of Primus or any Restricted Subsidiary to any other Restricted
  Subsidiary; provided that any subsequent issuance or transfer of any
  Capital Stock which results in any such Restricted Subsidiary ceasing to be
  a Restricted Subsidiary or any subsequent transfer of such Indebtedness not
  permitted by this clause (iii) (other than to us or another Restricted
  Subsidiary) shall be deemed, in each case, to constitute the incurrence of
  such Indebtedness, and provided further that Indebtedness to a Restricted
  Subsidiary must be subordinated in right of payment to the Notes;

     (iv) Indebtedness of Primus or a Restricted Subsidiary issued in
  exchange for, or the net proceeds of which are used to refinance or refund,
  then outstanding Indebtedness of Primus or a Restricted Subsidiary, other
  than Indebtedness Incurred under clauses (i), (iii), (vi), (viii), (ix) and
  (xii) of this paragraph, and any refinancings thereof in an amount not to
  exceed the amount so refinanced or refunded (plus premiums, accrued
  interest, and reasonable fees and expenses); provided that such new
  Indebtedness shall only be permitted under this clause (iv) if

       (A) in case the Notes are refinanced in part or the Indebtedness to
    be refinanced is pari passu with the Notes, such new Indebtedness, by
    its terms or by the terms of any agreement or instrument pursuant to
    which such new Indebtedness is issued or remains outstanding, is
    expressly made pari passu with, or subordinate in right of payment to,
    the remaining Notes,

                                      106
<PAGE>

       (B) in case the Indebtedness to be refinanced is subordinated in
    right of payment to the Notes, such new Indebtedness, by its terms or by
    the terms of any agreement or instrument pursuant to which such new
    Indebtedness is issued or remains outstanding, is expressly made
    subordinate in right of payment to the Notes at least to the extent that
    the Indebtedness to be refinanced is subordinated to the Notes and

       (C) such new Indebtedness, determined as of the date of Incurrence of
    such new Indebtedness, does not mature prior to the Stated Maturity of
    the Indebtedness to be refinanced or refunded, and the Average Life of
    such new Indebtedness is at least equal to the remaining Average Life of
    the Indebtedness to be refinanced or refunded; and provided further that
    in no event may our Indebtedness be refinanced by means of any
    Indebtedness of any Restricted Subsidiary pursuant to this clause (iv);

     (v) Indebtedness not to exceed, at any one time outstanding, 2.00 times

       (A) the Net Cash Proceeds received by us after May 18, 1998 from the
    issuance and sale of our Capital Stock (other than Redeemable Stock) to
    a Person that is not a Subsidiary, to the extent such Net Cash Proceeds
    have not been used pursuant to clause (C)(2) of the first paragraph or
    clauses (iii), (iv) or (vii) of the second paragraph of the "Limitation
    on Restricted Payments" covenant described below to make a Restricted
    Payment and

       (B) the Fair Market Value (as determined in good faith by our board
    of directors, whose determination shall be conclusive and evidenced by a
    Board Resolution) of property (other than cash and cash equivalents)
    used in a Permitted Business or common equity interests in a Person (the
    property and assets of such Person consisting primarily of
    telecommunications assets) that becomes a Restricted Subsidiary (such
    Fair Market Value being that of the common equity interests received
    pursuant to the transaction resulting in such Person becoming a
    Restricted Subsidiary), and, in each case, received by us after May 18,
    1998 from the issuance or sale of our Capital Stock (other than
    Redeemable Stock) to a Person that is not a Subsidiary to the extent
    such sale of Capital Stock has not been used pursuant to clauses (iii),
    (iv) and (vii) of the second paragraph of the "Limitation on Restricted
    Payments" covenant described below to make a Restricted Payment;
    provided that such Indebtedness does not mature prior to the Stated
    Maturity of the Notes and the Average Life of such Indebtedness is
    longer than that of the Notes;

     (vi) Indebtedness of Primus or any Restricted Subsidiary

       (A) in respect of performance, surety or appeal bonds or letters of
    credit supporting trade payables, in each case provided in the ordinary
    course of business;

       (B) under Currency Agreements and Interest Rate Agreements; provided
    that such agreements

         (a) are designed solely to protect us or any Restricted
      Subsidiary against fluctuation in foreign currency exchange rates or
      interest rates and

         (b) do not increase the Indebtedness of the obligor outstanding
      at any time other than as a result of fluctuations in foreign
      currency exchange rates or interest rates or by reason of fees,
      indemnities and compensation payable thereunder; and

       (C) arising from agreements providing for indemnification, adjustment
    of purchase price or similar obligations, or from Guarantees or letters
    of credit, surety bonds or performance bonds securing any of our
    obligations or any of our Restricted Subsidiaries pursuant to such
    agreements, in any case Incurred in connection with the disposition of
    any business, assets or Restricted Subsidiary (other than Guarantees of
    Indebtedness Incurred by any Person acquiring all or any portion of such
    business, assets or Restricted Subsidiary for the purpose of financing
    such acquisition), in a principal amount not to exceed the gross
    proceeds actually received by us or any Restricted Subsidiary in
    connection with such disposition;

                                      107
<PAGE>

     (vii) Indebtedness of Primus, to the extent that the net proceeds
  thereof are promptly

       (A) used to repurchase Notes tendered in a Change of Control Offer
    or

       (B) deposited to defease all of the Notes as described below under
    "Defeasance or Covenant Defeasance of Indenture";

     (viii) Indebtedness of a Restricted Subsidiary represented by a
  Guarantee of the Notes and any other Indebtedness permitted by and made in
  accordance with the "Limitation on Issuances of Guarantees of Indebtedness
  by Restricted Subsidiaries" covenant;

     (ix) Indebtedness of Primus or any Restricted Subsidiary not otherwise
  permitted hereunder in an aggregate principal amount which, when aggregated
  with the principal amount of all other Indebtedness then outstanding and
  incurred pursuant to this clause (ix), does not exceed $200 million at any
  one time outstanding;

     (x) Acquired Indebtedness;

     (xi) Strategic Subordinated Indebtedness; and

     (xii) Indebtedness of Primus or any Restricted Subsidiary arising from
  the honoring by a bank or other financial institution of a check or similar
  instrument inadvertently (except in the case of daylight overdrafts) drawn
  against insufficient funds in the ordinary course of business, provided
  that such Indebtedness is extinguished within three business days of
  Incurrence.

   (c) Notwithstanding any other provision of this "Limitation on Indebtedness"
covenant, the maximum amount of Indebtedness that Primus or a Restricted
Subsidiary may Incur pursuant to this "Limitation on Indebtedness" covenant
shall not be deemed to be exceeded with respect to any outstanding Indebtedness
due solely to the result of fluctuations in the exchange rates of currencies.

   (d) For purposes of determining any particular amount of Indebtedness under
this "Limitation on Indebtedness" covenant, Guarantees, Liens or obligations
with respect to letters of credit supporting Indebtedness otherwise included in
the determination of such particular amount shall not be included. For purposes
of determining compliance with this "Limitation on Indebtedness" covenant, in
the event that an item of Indebtedness meets the criteria of more than one of
the types of Indebtedness described in the above clauses, we, in our sole
discretion, shall classify and from time to time may reclassify such item of
Indebtedness and only be required to include the amount and type of such
Indebtedness in one of such clauses. (Section 1011)

 Limitation on Restricted Payments

   We will not, and will not permit any Restricted Subsidiary to, directly or
indirectly,

     (i) (A) declare or pay any dividend or make any distribution in respect
  of our Capital Stock to the holders thereof (other than dividends or
  distributions payable solely in shares of Capital Stock (other than
  Redeemable Stock) or in options, warrants or other rights to acquire such
  shares of Capital Stock) or

     (B) declare or pay any dividend or make any distribution in respect of
  the Capital Stock of any Restricted Subsidiary to any Person other than
  dividends and distributions payable to Primus or any Restricted Subsidiary
  or to all holders of Capital Stock of such Restricted Subsidiary on a pro
  rata basis,

     (ii) purchase, redeem, retire or otherwise acquire for value any shares
  of Capital Stock (including options, warrants or other rights to acquire
  such shares of Capital Stock) held by any Person other than a Restricted
  Subsidiary,

     (iii) make any voluntary or optional principal payment, or voluntary or
  optional redemption, repurchase, defeasance, or other acquisition or
  retirement for value of Subordinated Indebtedness or

     (iv) make any Investment, other than a Permitted Investment, in any
  Person (such payments or any other actions described in clauses (i) through
  (iv) being collectively "Restricted Payments") if, at the time of, and
  after giving effect to, the proposed Restricted Payment:

                                      108
<PAGE>

       (A) a Default or Event of Default shall have occurred and be
    continuing;

       (B) the Company could not Incur at least $1.00 of Indebtedness under
    the first paragraph of the "Limitation on Indebtedness" covenant; or

       (C) the aggregate amount expended for all Restricted Payments (the
    amount so expended, if other than in cash, to be determined in good
    faith by our board of directors, whose determination shall be
    conclusive and evidenced by a Board Resolution) after the date of the
    Indenture shall exceed the sum of

         (1) the remainder of

                 (a) 100% of the aggregate amount of the Consolidated Cash
              Flow (determined by excluding income resulting from transfers of
              assets received by Primus or a Restricted Subsidiary from an
              Unrestricted Subsidiary) accrued on a cumulative basis during
              the period (taken as one accounting period) beginning on the
              first day of the last fiscal quarter immediately preceding the
              Closing Date and ending on the last day of the last fiscal
              quarter preceding the Transaction Date minus

                  (1) the product of 1.75 times cumulative Consolidated Fixed
               Charges accrued on a cumulative basis during the period (taken
               as one accounting period) beginning on the first day of the
               last fiscal quarter immediately preceding the Closing Date and
               ending on the last day of the last fiscal quarter preceding the
               Transaction Date plus

                  (2) the aggregate Net Cash Proceeds received by us after the
               Closing Date from the issuance and sale of our Capital Stock
               (other than Redeemable Stock) to a Person who is not a
               Subsidiary (except to the extent such Net Cash Proceeds are
               used to incur new Indebtedness outstanding pursuant to clause
               (v) of the paragraph (b) of the "Limitation on Indebtedness"
               covenant) plus

                  (3) the aggregate Net Cash Proceeds received after the
               Closing Date by us from the issuance or sale of debt securities
               that have been converted into or exchanged for Capital Stock
               (other than Redeemable Stock) together with the aggregate cash
               received by us at the time of such conversion or exchange plus

                  (4) without duplication of any amount included in the
               calculation of Consolidated Cash Flow, in the case of repayment
               of, or return of capital in respect of, any Investment
               constituting a Restricted Payment made after the Closing Date
               and reducing the amount of Restricted Payments otherwise
               permitted under this clause (C), an amount equal to the lesser
               of the return of capital with respect to such Investment and
               the cost of such Investment, in either case less the cost of
               the disposition of such Investment.

   The foregoing provision shall not be violated by reason of:

     (i) the payment of any dividend within 60 days after the date of
  declaration thereof if, at said date of declaration, such payment would
  comply with the foregoing paragraph;

     (ii) the redemption, repurchase, defeasance or other acquisition or
  retirement for value of Indebtedness that is subordinated in right of
  payment to the Notes including premium, if any, and accrued and unpaid
  interest, with the proceeds of, or in exchange for, Indebtedness Incurred
  under clause (iv) of paragraph (b) of the "Limitation on Indebtedness"
  covenant;

     (iii) the repurchase, redemption or other acquisition of Capital Stock
  in exchange for, or out of the proceeds of a substantially concurrent
  offering of, shares of Capital Stock (other than Redeemable Stock) (except
  to the extent such proceeds are used to incur new Indebtedness pursuant to
  clause (v) of paragraph (b) of the "Limitation on Indebtedness" covenant);

     (iv) the acquisition of Indebtedness which is subordinated in right of
  payment to the Notes in exchange for, or out of the proceeds of, a
  substantially concurrent offering of, shares of Capital Stock

                                      109
<PAGE>

  (other than Redeemable Stock) (except to the extent such proceeds are used
  to incur new Indebtedness pursuant to clause (v) of paragraph (b) of the
  "Limitation on Indebtedness" covenant);

     (v) payments or distributions to dissenting stockholders pursuant to
  applicable law, pursuant to or in connection with a consolidation, merger
  or transfer of assets that complies with the provisions of the Indenture
  applicable to mergers, consolidations and transfers of all or substantially
  all of our property and assets;

     (vi) cash payments in lieu of the issuance of fractional shares issued
  in connection with the exercise of any Common Stock warrants;

     (vii) Investments in Permitted Businesses acquired in exchange for
  Capital Stock (other than Redeemable Stock) or the Net Cash Proceeds from
  the issuance and sale of such Capital Stock (except to the extent such
  proceeds are used to incur new Indebtedness pursuant to clause (v) of
  paragraph (b) of the "Limitation on Indebtedness" covenant); provided that
  such proceeds are so used within 270 days of the receipt thereof;

     (viii) the purchase of any Subordinated Indebtedness at a purchase price
  not greater than 101% of the principal amount thereof, together with
  accrued interest, if any, thereof in the event of a Change of Control in
  accordance with provisions similar to the "Repurchase of Notes upon a
  Change of Control" covenant; provided that prior to such purchase we have
  made the Change of Control offer as provided in such covenant with respect
  to the Notes and have purchased all Notes validly tendered for payment in
  connection with such Change of Control Offer; and

     (ix) other Restricted Payments not to exceed $5.0 million; provided
  that, except in the case of clause (i), no Default or Event of Default
  shall have occurred and be continuing or occur as a consequence of the
  actions or payments set forth therein. (Section 1012)

   Each Restricted Payment permitted pursuant to the immediately preceding
paragraph (other than (1) a Restricted Payment referred to in clause (ii)
thereof, (2) an exchange of Capital Stock for Capital Stock or an exchange of
Indebtedness for Capital Stock referred to in clauses (iii) or (iv) thereof or
(3) an Investment referred to in clause (vii) thereof) and the Net Cash
Proceeds from any issuance of Capital Stock referred to in clauses (iii), (iv)
and (vii) shall be included in calculating whether the conditions of clause (C)
of the first paragraph of this "Limitation on Restricted Payments" covenant
have been met with respect to any subsequent Restricted Payments.

   Any Restricted Payments made other than in cash shall be valued at Fair
Market Value. The amount of any Investment "outstanding" at any time shall be
deemed to be equal to the amount of such Investment on the date made, less the
return of capital, repayment of loans, and release of Guarantees, in each case
of or to us and our Restricted Subsidiaries with respect to such Investment (up
to the amount of such Investment on the date made).

 Limitation on Dividend and Other Payment Restrictions Affecting Restricted
 Subsidiaries

   So long as any of the Notes are outstanding, we will not, and will not
permit any Restricted Subsidiary to, create or otherwise cause or suffer to
exist or become effective any consensual encumbrance or restriction of any kind
on the ability of any Restricted Subsidiary to:

     (i) pay dividends or make any other distributions permitted by
  applicable law on any Capital Stock of such Restricted Subsidiary owned by
  us or any other Restricted Subsidiary,

     (ii) pay any indebtedness owed to us or any other Restricted Subsidiary,

     (iii) make loans or advances to us or any other Restricted Subsidiary,
  or

     (iv) transfer any of its property or assets to us or any other
  Restricted Subsidiary.

                                      110
<PAGE>

   The foregoing provisions shall not restrict any encumbrances or
restrictions:

     (i) existing on the Closing Date in the Indenture or any other
  agreements in effect on the Closing Date, and any extensions, refinancings,
  renewals or replacements of such agreements; provided that the encumbrances
  and restrictions in any such extensions, refinancings, renewals or
  replacements are no less favorable in any material respect to the holders
  of the Notes than those encumbrances or restrictions that are then in
  effect and that are being extended, refinanced, renewed or replaced;

     (ii) contained in the terms of any Indebtedness or any agreement
  pursuant to which such Indebtedness was issued if the encumbrance or
  restriction applies only in the event of a payment default or default with
  respect to a financial covenant contained in such Indebtedness or agreement
  and such encumbrance or restriction is not materially more disadvantageous
  to the holders of the Notes than is customary in comparable financings (as
  determined by us) and we determine that any such encumbrance or restriction
  will not materially affect our ability to make principal or interest
  payments on the Notes;

     (iii) existing under or by reason of applicable law;

     (iv) existing with respect to any Person or the property or assets of
  such Person acquired by us or any Restricted Subsidiary, existing at the
  time of such acquisition and not incurred in contemplation thereof, which
  encumbrances or restrictions are not applicable to any Person or the
  property or assets of any Person other than such Person or the property or
  assets of such Person so acquired;

     (v) in the case of clause (iv) of the first paragraph of this
  "Limitation on Dividend and Other Payment Restrictions Affecting Restricted
  Subsidiaries" covenant,

       (A) that restrict in a customary manner the subletting, assignment
    or transfer of any property or asset that is, or is subject to, a
    lease, purchase mortgage obligation, license, conveyance or contract or
    similar property or asset,

       (B) existing by virtue of any transfer of, agreement to transfer,
    option or right with respect to, or Lien on, any of our property or
    assets or those of any Restricted Subsidiary not otherwise prohibited
    by the Indenture or

       (C) arising or agreed to in the ordinary course of business, not
    relating to any Indebtedness, and that do not, individually or in the
    aggregate, detract from the value of our property or assets or those of
    any Restricted Subsidiary in any manner material to Primus or any
    Restricted Subsidiary; or

     (vi) with respect to a Restricted Subsidiary and imposed pursuant to an
  agreement that has been entered into for the sale or disposition of all or
  substantially all of the Capital Stock of, or property and assets of, such
  Restricted Subsidiary.

Nothing contained in this "Limitation on Dividend and Other Payment
Restrictions Affecting Restricted Subsidiaries" covenant shall prevent us or
any Restricted Subsidiary from (1) creating, incurring, assuming or suffering
to exist any Liens otherwise permitted in the "Limitation on Liens" covenant or
(2) restricting the sale or other disposition of property or assets of Primus
or any of its Restricted Subsidiaries that secure Indebtedness of Primus or any
of its Restricted Subsidiaries. (Section 1013)

 Limitation on the Issuance and Sale of Capital Stock of Restricted
 Subsidiaries

   We will not sell, transfer, convey or otherwise dispose of and will not
permit any Restricted Subsidiary, directly or indirectly, to issue, transfer,
convey, sell, lease or otherwise dispose of any shares of Capital Stock
(including options, warrants or other rights to purchase shares of such Capital
Stock) of such or any other Restricted Subsidiary to any Person except:

     (i) to Primus or a Restricted Subsidiary,

     (ii) issuances of director's qualifying shares or sales to foreign
  nationals of shares of Capital Stock of non-U.S. Restricted Subsidiaries to
  the extent required by law and

                                      111
<PAGE>

     (iii) issuances and sales of Capital Stock of Restricted Subsidiaries if

       (A) the Net Cash Proceeds from such issuance, transfer, conveyance,
    sale, lease or other disposition are applied in accordance with the
    provisions of the "Limitation on Asset Sales" covenant,

       (B) immediately after giving effect to such issuance, transfer,
    conveyance, sale, lease or other disposition, such Restricted Subsidiary
    would no longer constitute a Restricted Subsidiary, and

       (C) any Investment in such Person remaining after giving effect to
    such issuance, transfer, conveyance, sale, lease or other disposition
    would have been permitted to be made under the "Limitation on Restricted
    Payments" covenant if made on the date of such issuance, transfer,
    conveyance, sale, lease or other disposition (valued as provided in the
    definition of "Investment"). (Section 1014)

 Limitation on Transactions with Shareholders and Affiliates

   We will not, and will not permit any Restricted Subsidiary to, directly or
indirectly, enter into, renew or extend any transaction (including, without
limitation, the purchase, sale, lease or exchange of property or assets, or
the rendering of any service) with any holder (or any Affiliate of such
holder) of 5% or more of any class of Capital Stock or with any Affiliate or
any Restricted Subsidiary, unless

     (i) such transaction or series of transactions is on terms no less
  favorable to us or such Restricted Subsidiary than those that could be
  obtained in a comparable arm's-length transaction with a Person that is not
  such a holder or an Affiliate,

     (ii) if such transaction or series of transactions involves aggregate
  consideration in excess of $5.0 million, then such transaction or series of
  transactions is approved by a majority of our board of directors, including
  the approval of a majority of the independent, disinterested directors, and
  is evidenced by a resolution of our board of directors, and

     (iii) if such transaction or series of transactions involves aggregate
  consideration in excess of $25.0 million, then we or such Restricted
  Subsidiary will deliver to the Trustee a written opinion as to the fairness
  to us or such Restricted Subsidiary of such transaction from a financial
  point of view from a nationally recognized investment banking firm (or, if
  an investment banking firm is generally not qualified to give such an
  opinion, by a nationally recognized appraisal firm or accounting firm). Any
  such transaction or series of transactions shall be conclusively deemed to
  be on terms no less favorable to us or such Restricted Subsidiary than
  those that could be obtained in an arm's-length transaction if such
  transaction or transactions are approved by a majority of our board of
  directors, including a majority of the independent, disinterested
  directors, and are evidenced by a resolution of our board of directors.

   The foregoing limitation does not limit, and will not apply to

     (i) any transaction between us and any of our Restricted Subsidiaries or
  between Restricted Subsidiaries;

     (ii) the payment of reasonable and customary regular fees to our
  directors who are not our employees;

     (iii) any Restricted Payments not prohibited by the "Limitation on
  Restricted Payments" covenant;

     (iv) transactions provided for in the Employment Agreement as in effect
  on the Closing Date; and

     (v) loans and advances to employees of Primus or any Restricted
  Subsidiary not exceeding at any one time outstanding $2.0 million in the
  aggregate, in the ordinary course of business and in accordance with past
  practice. (Section 1015)


                                      112

 Limitation on Liens

   Under the terms of the Indenture, we will not, and will not permit any
Restricted Subsidiary to, create, incur, assume or suffer to exist any Lien
(other than Permitted Liens) on any of our assets or properties of any
character (including, without limitation, licenses and trademarks), or any
shares of Capital Stock or Indebtedness of any Restricted Subsidiary, without
making effective provision for all of the Notes and all other amounts due
under the Indenture to be directly secured equally and ratably with (or prior
to) the obligation or liability secured by such Lien. (Section 1016)

 Limitation on Asset Sales

   We will not, and will not permit any Restricted Subsidiary to, make any
Asset Sale unless (i) Primus or the Restricted Subsidiary, as the case may be,
receives consideration at the time of such sale or other disposition at least
equal to the Fair Market Value of the assets sold or disposed of as determined
by the good-faith judgment of our board of directors, which determination, in
each case where such Fair Market Value is greater than $5.0 million, will be
evidenced by a Board Resolution and (ii) at least 75% of the consideration
received for such sale or other disposition consists of cash or cash
equivalents or the assumption of unsubordinated Indebtedness.

   We shall, or shall cause the relevant Restricted Subsidiary to, within 360
days after the date of receipt of the Net Cash Proceeds from an Asset Sale,
(i) (A) apply an amount equal to such Net Cash Proceeds to permanently repay
our unsubordinated Indebtedness or Indebtedness of any Restricted Subsidiary,
in each case owing to a Person other than Primus or any of its Restricted
Subsidiaries or (B) invest an equal amount, or the amount not so applied
pursuant to clause (A) in long-term property or assets of a nature or type or
that are used in a business (or in a company having property and assets of a
nature or type, or engaged in a business) similar or related to the nature or
type of the property and assets of, or the business of, Primus and its
Restricted Subsidiaries existing on the date of such investment (as determined
in good faith by our board of directors, whose determination shall be
conclusive and evidenced by a Board Resolution) and (ii) apply (no later than
the end of the 360-day period referred to above) such excess Net Cash Proceeds
(to the extent not applied pursuant to clause (i)) as provided in the
following paragraphs of this "Limitation on Asset Sales" covenant. The amount
of such Net Cash Proceeds required to be applied (or to be committed to be
applied) during such 360-day period referred to above in the preceding
sentence and not applied as so required by the end of such period shall
constitute "Excess Proceeds."

   If, as of the first day of any calendar month, the aggregate amount of
Excess Proceeds not theretofore subject to an Excess Proceeds Offer (as
defined below) totals at least $10.0 million, we must, not later than the 30th
Business Day thereafter, make an offer (an "Excess Proceeds Offer") to
purchase from the holders on a pro rata basis an aggregate principal amount of
Notes equal to the Proportionate Share of the Excess Proceeds on such date, at
a purchase price equal to 100% of the principal amount of the Notes, plus, in
each case, accrued and unpaid interest to the date of purchase (the "Excess
Proceeds Payment").

   We shall commence an Excess Proceeds Offer by mailing a notice to the
Trustee and each holder stating:

     (i) that the Excess Proceeds Offer is being made pursuant to this
  "Limitation on Asset Sales" covenant and that all Notes validly tendered
  will be accepted for payment on a pro rata basis;

     (ii) the purchase price and the date of purchase (which shall be a
  Business Day no earlier than 30 days nor later than 60 days from the date
  such notice is mailed) (the "Excess Proceeds Payment Date");

     (iii) that any Note not tendered will continue to accrue interest
  pursuant to its terms;

     (iv) that, unless we default in the payment of the Excess Proceeds
  Payment, any Note accepted for payment pursuant to the Excess Proceeds
  Offer shall cease to accrue interest on and after the Excess Proceeds
  Payment Date;

     (v) that holders electing to have a Note purchased pursuant to the
  Excess Proceeds Offer will be required to surrender the Note, together with
  the form entitled "Option of the Holder to Elect Purchase"

                                      113
<PAGE>

  on the reverse side of the Note completed, to the Paying Agent at the
  address specified in the notice prior to the close of business on the
  Business Day immediately preceding the Excess Proceeds Payment Date;

     (vi) that holders will be entitled to withdraw their election if the
  Paying Agent receives, not later than the close of business on the third
  Business Day immediately preceding the Excess Proceeds Payment Date, a
  telegram, facsimile transmission or letter setting forth the name of such
  holder, the principal amount of Notes delivered for purchase and a
  statement that such holder is withdrawing his election to have such Notes
  purchased; and

     (vii) that holders whose Notes are being purchased only in part will be
  issued new Notes equal in principal amount to the unpurchased portion of
  the Notes surrendered; provided that each Note purchased and each new Note
  issued shall be in a principal amount of $1,000 or integral multiples
  thereof.

   On the Excess Proceeds Payment Date, the Company shall

     (i) accept for payment on a pro rata basis Notes or portions thereof
  tendered pursuant to the Excess Proceeds Offer up to the Proportionate
  Share of such Excess Proceeds;

     (ii) deposit with the Paying Agent money sufficient to pay the purchase
  price of all Notes or portions thereof so accepted; and

     (iii) deliver, or cause to be delivered, to the Trustee all Notes or
  portions thereof so accepted together with an Officer's Certificate
  specifying the Notes or portions thereof accepted for payment by the
  Company.

The Paying Agent shall promptly mail to the holders of Notes so accepted
payment in an amount equal to the purchase price, and the Trustee shall
promptly authenticate and mail to such holders a new Note equal in principal
amount to any unpurchased portion of the Note surrendered; provided that each
Note purchased and each new Note issued shall be in a principal amount of
$1,000 or integral multiples thereof. We will publicly announce the results of
the Excess Proceeds Offer as soon as practicable after the Excess Proceeds
Payment Date. For purposes of this "Limitation on Asset Sales" covenant, the
Trustee shall act as the Paying Agent.

   We will comply with Rule 14e-1 under the Securities Exchange Act of 1934 and
any other securities laws and regulations thereunder to the extent such laws
and regulations are applicable, in the event that such Excess Proceeds are
received by the Company under this "Limitation on Asset Sales" covenant and the
Company is required to repurchase Notes as described above. (Section 1017)

 Limitation on Issuances of Guarantees of Indebtedness by Restricted
 Subsidiaries

   We will not permit any Restricted Subsidiary, directly or indirectly, to
guarantee, assume or in any other manner become liable with respect to any of
our Indebtedness, other than Indebtedness under Credit Facilities incurred
under clauses (i) and (ii) of the "Limitation on Indebtedness" covenant, unless
(i) such Restricted Subsidiary simultaneously executes and delivers a
supplemental indenture to the Indenture providing for a Guarantee of the Notes
on terms substantially similar to the guarantee of such Indebtedness, except
that if such Indebtedness is by its express terms subordinated in right of
payment to the Notes, any such assumption, Guarantee or other liability of such
Restricted Subsidiary with respect to such Indebtedness shall be subordinated
in right of payment to such Restricted Subsidiary's assumption, Guarantee of
other liability with respect to the Notes substantially to the same extent as
such Indebtedness is subordinated to the Notes and (ii) such Restricted
Subsidiary waives, and will not in any manner whatsoever claim or take the
benefit or advantage of, any rights of reimbursement, indemnity or subrogation
or any other rights against Primus or any other Restricted Subsidiary as a
result of any payment by such Restricted Subsidiary under its Guarantee.

   Notwithstanding the foregoing, any Guarantee by a Restricted Subsidiary may
provide by its terms that it will be automatically and unconditionally released
and discharged upon (i) any sale, exchange or transfer, to any Person not an
Affiliate of us, of all of our and each Restricted Subsidiary's Capital Stock
in, or all or substantially all of the assets of, such Restricted Subsidiary
(which sale, exchange or transfer is not prohibited

                                      114
<PAGE>

by the Indenture) or (ii) the release or discharge of the guarantee which
resulted in the creation of such Guarantee, except a discharge or release by or
as a result of payment under such guarantee. (Section 1018)

 Business of the Company

   We will not, and will not permit any Restricted Subsidiary to, be
principally engaged in any business or activity other than a Permitted
Business.

 Limitation on Investments in Unrestricted Subsidiaries

   We will not make, and will not permit any of our Restricted Subsidiaries to
make, any Investments in Unrestricted Subsidiaries if, at the time thereof, the
aggregate amount of such Investments would exceed the amount of Restricted
Payments then permitted to be made pursuant to the "Limitation on Restricted
Payments" covenant. Any Investments in Unrestricted Subsidiaries permitted to
be made pursuant to this covenant (i) will be treated as the making of a
Restricted Payment in calculating the amount of Restricted Payments made by the
Company or a Subsidiary and (ii) may be made in cash or property (if made in
property, the Fair Market Value thereof as determined by our board of directors
(whose determination shall be conclusive and evidenced by a Board Resolution)
shall be deemed to be the amount of such Investment for the purpose of clause
(i)). (Section 1020)

 Provision of Financial Statements and Reports

   We will file on a timely basis with the Securities and Exchange Commission,
to the extent such filings are accepted by the Commission and whether or not we
have a class of securities registered under the Securities Exchange Act of
1934, the annual reports, quarterly reports and other documents that we would
be required to file if we were subject to Section 13 or 15 of the Exchange Act.
All such annual reports shall include the geographic segment financial
information contemplated by Item 101(d) of Regulation S-K under the Securities
Act of 1933 and all such quarterly reports shall provide the same type of
interim financial information that, as of the date of the Indenture, currently
is our practice to provide. We will also be required (a) to file with the
Trustee, and provide to each holder, without cost to such holder, copies of
such reports and documents within 15 days after the date on which we file such
reports and documents with the Commission or the date on which we would be
required to file such reports and documents if we were so required, and (b) if
filing such reports and documents with the Commission is not accepted by the
Commission or is prohibited under the Exchange Act, to supply at our cost
copies of such reports and documents to any prospective holder promptly upon
request. (Section 1009)

 Other

   We will not, and will not permit any of our Restricted Subsidiaries to,
Incur any Indebtedness (other than fees and expenses which accrue by the terms
of the TresCom credit facility) under the TresCom credit facility and we will
cause the TresCom credit facility to be terminated as soon as practicable.

Repurchase of Notes upon a Change of Control

   Upon the occurrence of a Change of Control, each holder shall have the right
to require us to repurchase all or any part of its Notes at a purchase price in
cash pursuant to the offer described below (the "Change of Control Offer")
equal to 101% of the principal amount thereof, plus accrued and unpaid interest
to the date of purchase (subject to the right of holders of record to receive
interest on the relevant interest payment date) (the "Change of Control
Payment").

                                      115
<PAGE>

   Within 30 days following any Change of Control, we will mail a notice to the
Trustee and each holder stating:

     (i) that a Change of Control has occurred, that the Change of Control
  Offer is being made pursuant to this "Repurchase of Notes upon a Change of
  Control" covenant and that all Notes validly tendered will be accepted for
  payment;

     (ii) the purchase price and the date of purchase (which shall be a
  Business Day no earlier than 30 days nor later than 60 days from the date
  such notice is mailed) (the "Change of Control Payment Date");

     (iii) that any Note not tendered will continue to accrue interest
  pursuant to its terms;

     (iv) that, unless we default in the payment of the Change of Control
  Payment, any Note accepted for payment pursuant to the Change of Control
  Offer shall cease to accrue interest on and after the Change of Control
  Payment Date;

     (v) that holders electing to have any Note or portion thereof purchased
  pursuant to the Change of Control Offer will be required to surrender such
  Note, together with the form entitled "Option of the Holder to Elect
  Purchase" on the reverse side of such Note completed, to the Paying Agent
  at the address specified in the notice prior to the close of business on
  the third Business Day immediately preceding the Change of Control Payment
  Date;

     (vi) that holders will be entitled to withdraw their election if the
  Paying Agent receives, not later than the close of business on the third
  Business Day immediately preceding the Change of Control Payment Date, a
  telegram, telex, facsimile transmission or letter setting forth the name of
  such holder, the principal amount of Notes delivered for purchase and a
  statement that such holder is withdrawing his election to have such Notes
  purchased; and

     (vii) that holders whose Notes are being purchased only in part will be
  issued new Notes equal in principal amount to the unpurchased portion of
  the Notes surrendered; provided that each Note purchased and each new Note
  issued shall be in a principal amount of $1,000 or integral multiples
  thereof.

   On the Change of Control Payment Date, we shall:

     (i) accept for payment Notes or portions thereof tendered pursuant to
  the Change of Control Offer;

     (ii) deposit with the Paying Agent money sufficient to pay the purchase
  price of all Notes or portions thereof so accepted; and

     (iii) deliver, or cause to be delivered, to the Trustee, all Notes or
  portions thereof so accepted together with an Officer's Certificate
  specifying the Notes or portions thereof accepted for payment by the
  Company.

The Paying Agent shall promptly mail, to the holders of Notes so accepted,
payment in an amount equal to the purchase price, and the Trustee shall
promptly authenticate and mail to such holders a new Note equal in principal
amount of any unpurchased portion of the Notes surrendered; provided that each
Note purchased and each new Note issued shall be in a principal amount of
$1,000 or integral multiples thereof. We will publicly announce the results of
the Change of Control Offer on or as soon as practicable after the Change of
Control Payment Date. For purposes of this "Repurchase of Notes upon a Change
of Control" covenant, the Trustee shall act as Paying Agent.

   We will comply with Rule 14e-1 under the Securities Exchange Act of 1934 and
any other securities laws and regulations thereunder to the extent such laws
and regulations are applicable in the event that a Change of Control occurs and
we are required to repurchase the Notes under this "Repurchase of Notes upon a
Change of Control" covenant. (Section 1010)

   If we are unable to repay all of our indebtedness that would prohibit
repurchase of the Notes or are unable to obtain the consents of the holders of
our indebtedness, if any, outstanding at the time of a Change of Control whose
consent would be so required to permit the repurchase of Notes, then we will
have breached such

                                      116
<PAGE>

covenant. Our failure to repurchase Notes at the conclusion of the Change of
Control Offer will constitute an Event of Default without any waiting period or
notice requirements.

   There can be no assurances that we will have sufficient funds available at
the time of any Change of Control to make any debt payment (including
repurchases of Notes) required by the foregoing covenant (as well as may be
contained in other of our securities which might be outstanding at the time).
The above covenant requiring us to repurchase the Notes will, unless the
consents referred to above are obtained, require us to repay all indebtedness
then outstanding which by its terms would prohibit such Note repurchase, either
prior to or concurrently with such note repurchase.

Consolidation, Merger and Sale of Assets

   We will not consolidate with, merge with or into, or sell, convey, transfer,
lease or otherwise dispose of all or substantially all of our property and
assets (as an entirety or substantially an entirety in one transaction or a
series of related transactions) to, any Person or permit any Person to merge
with or into us and we will not permit any of our Restricted Subsidiaries to
enter into any such transaction or series of transactions if such transaction
or series of transactions, in the aggregate, would result in the sale,
assignment, conveyance, transfer, lease or other disposition of all or
substantially all of our properties and assets or of us and our Restricted
Subsidiaries, taken as a whole, to any other Person or Persons, unless:

     (i) we will be the continuing Person, or the Person (if other than us)
  formed by such consolidation or into which we are merged or that acquired
  or leased such property and assets of us will be a corporation, partnership
  or trust organized and validly existing under the laws of the United States
  of America or any jurisdiction thereof and shall expressly assume, by a
  supplemental indenture, executed and delivered to the Trustee, all of our
  obligations with respect to the Notes and under the Indenture;

     (ii) immediately after giving effect to such transaction, no Default or
  Event of Default shall have occurred and be continuing;

     (iii) immediately after giving effect to such transaction on a pro forma
  basis we, or any Person becoming the successor obligor of the Notes, as the
  case may be, could Incur at least $1.00 of Indebtedness under paragraph (a)
  of the "Limitation on Indebtedness" covenant; and

     (iv) we deliver to the Trustee an Officer's Certificate (attaching the
  arithmetic computations to demonstrate compliance with clause (iii)) and
  Opinion of Counsel stating that such consolidation, merger or transfer and,
  if required in connection with such transaction, the related supplemental
  indenture complies with this provision and that all conditions precedent
  provided for herein relating to such transaction have been complied with;
  provided, however, that clause (iii) above does not apply if, in the good
  faith determination of our board of directors, whose determination shall be
  evidenced by a Board Resolution, the principal purpose of such transaction
  is to change our state of incorporation; and provided further that any such
  transaction shall not have as one of its purposes the evasion of the
  foregoing limitations. (Section 801)

Events of Default

   The following events will be defined as "Events of Default" in the
Indenture:

     (a) default in the payment of interest or Liquidated Damages, if any, on
  the Notes when due and payable and continuance of such default for a period
  of 30 days;

     (b) default in the payment of principal of (or premium, if any, on) any
  Note at its Stated Maturity, upon acceleration, redemption or otherwise;

  by the Trustee or the holders of 25% or more in aggregate principal amount
  of the Notes;

     (f) there occurs with respect to any issue or issues of Indebtedness of
  Primus or any Restricted Subsidiary having an outstanding principal amount

  created,

       (I) an event of default that has caused the holder thereof to
    declare such Indebtedness to be due and payable prior to its Stated
    Maturity and such Indebtedness has not been discharged in full or such
    acceleration has not been rescinded or annulled by the earlier of

         (x) the expiration of any applicable grace period or

         (y) the thirtieth day after such default and/or

       (II) the failure to make a principal payment at the final (but not
    any interim) fixed maturity and such defaulted payment shall not have
    been made, waived or extended by the earlier of

         (x) the expiration of any applicable grace period or

         (y) the thirtieth day after such default;

     (g) any final judgment or order (not covered by insurance) for the
  payment of money in excess of $10.0 million in the aggregate for all such
  final judgments or orders against all such Persons (treating any
  deductibles, self-insurance or retention as not so covered) shall be
  rendered against us or any Restricted Subsidiary and shall not be paid or
  discharged, and there shall be any period of 30 consecutive days following
  entry of the final judgment or order that causes the aggregate amount for
  all such final judgments or orders outstanding and not paid or discharged
  against all such Persons to exceed $10.0 million during which a stay of
  enforcement of such final judgment or order, by reason of a pending appeal
  or otherwise, shall not be in effect;

     (h) a court having jurisdiction in the premises enters a decree or order
  for

       (A) relief in respect of us or any of our Significant Subsidiaries
    in an involuntary case under any applicable bankruptcy, insolvency or
    other similar law now or hereafter in effect,

       (B) appointment of a receiver, liquidator, assignee, custodian,
    trustee, sequestrator or similar official of us or any of our
    Significant Subsidiaries or for all or substantially all of our
    property and assets or those of our Significant Subsidiaries or

       (C) the winding up or liquidation of the affairs of Primus or any of
    its Significant Subsidiaries and, in each case, such decree or order
    shall remain unstayed and in effect for a period of 30 consecutive
    days; or

         (i) we or any of its Significant Subsidiaries

       (A) commences a voluntary case under any applicable bankruptcy,

    to the entry of an order for relief in an involuntary case under any
    such law,

       (B) consents to the appointment of or taking possession by a
    receiver, liquidator, assignee, custodian, trustee, sequestrator or

    all or substantially all of the property and assets of Primus or any of
    its Significant Subsidiaries or

       (C) effects any general assignment for the benefit of creditors.
    (Section 501)

   If an Event of Default (other than an Event of Default specified in clause
(h) or (i) above) occurs and is continuing under the Indenture, the Trustee or
the holders of at least 25% in aggregate principal amount of the

                                      118
<PAGE>

Notes, then outstanding, by written notice to us (and to the Trustee if such
notice is given by the holders), may, and the Trustee at the request of such
holders shall, declare the principal of, premium, if any, and accrued but
unpaid interest and liquidated damages, if any, on the Notes to be immediately
due and payable. Upon a declaration of acceleration, such principal of,
premium, if any, and accrued interest and liquidation damages, if any, shall be
immediately due and payable. In the event of a declaration of acceleration
because an Event of Default set forth in clause (f) above has occurred and is
continuing, such declaration of acceleration shall be automatically rescinded
and annulled if the Indebtedness that is the subject of such Event of Default
has been discharged or the holders thereof have rescinded their declaration of
acceleration in respect of such Indebtedness, and written notice of such
discharge or rescission, as the case may be, shall have been given to the
trustee by us and countersigned by the holders of such Indebtedness or a
trustee, fiduciary or agent for such holders, within 60 days after such
declaration of acceleration in respect of the Notes, and no other Event of
Default has occurred during such 60-day period which has not been cured or
waived during such period. If an Event of Default specified in clause (h) or
(i) above occurs, the principal of, premium, if any, and accrued interest and
liquidated damages, if any, on the Notes then outstanding shall ipso facto
become and be immediately due and payable without any declaration or other act
on the part of the trustee or any holder. The holders of at least a majority in
principal amount of the outstanding Notes by written notice to us and to the
Trustee, may waive all past defaults and rescind and annul a declaration of
acceleration and its consequences if, among other things, (i) all existing
Events of Default, other than the nonpayment of the principal of, premium, if
any, and accrued and unpaid interest and Liquidated Damages, if any, on the
Notes that have become due solely by such declaration of acceleration, have
been cured or waived and (ii) the rescission, in the Opinion of Counsel, would
not conflict with any judgment or decree of a court of competent jurisdiction.
(Section 502)

   The holders of at least a majority in aggregate principal amount of the
outstanding Notes may direct the time, method and place of conducting any
proceeding for any remedy available to the trustee or exercising any trust or
power conferred on the trustee. However, the trustee may refuse to follow any
direction that conflicts with law or the Indenture, that may involve the
Trustee in personal liability, or that the trustee determines in good faith may
be unduly prejudicial to the rights of holders of Notes not joining in the
giving of such direction and may take any other action it deems proper that is
not inconsistent with any such direction received from holders of Notes. No
holder may pursue any remedy with respect to the Indenture or the Notes unless:

     (i) the holder gives the trustee written notice of a continuing Event of
  Default;

     (ii) the holders of at least 25% in aggregate principal amount of
  outstanding Notes make a written request to the Trustee to pursue the
  remedy;

     (iii) such holder or holders offer the trustee indemnity satisfactory to
  the trustee against any costs, liability or expense;

     (iv) the trustee does not comply with the request within 60 days after
  receipt of the request and the offer of indemnity; and

     (v) during such 60-day period, the holders of a majority in aggregate
  principal amount of the outstanding Notes do not give the trustee a
  direction that is inconsistent with the request.

However, such limitations do not apply to the right of any holder of a Note to
receive payment of the principal of, premium, if any, or interest or Liquidated
Damages, if any, on, such Note or to bring suit for the enforcement of any such
payment, on or after the due date expressed in the Notes, which right shall not
be impaired or affected without the consent of the holder. (Sections 507, 508
and 512)

   The indenture will require certain of our officers to certify, on or before
a date not more than 90 days after the end of each fiscal year, that a review
has been conducted of our activities and our performance under the indenture
and that we have fulfilled all obligations thereunder or, if there has been a
default in the fulfillment of any such obligation, specifying each such default
and the nature and status thereof. We will also be obligated to notify the
trustee of any default or defaults in the performance of any covenants or
agreements under the indenture. (Section 1008)

Defeasance or Covenant Defeasance of Indenture

   We may, at our option and at any time, elect to have our obligations upon
the Notes discharged with respect to the outstanding Notes ("defeasance"). Such
defeasance means that we will be deemed to have paid and discharged the entire
Indebtedness represented by the outstanding Notes and to have satisfied all our
other obligations under such Notes and the indenture insofar as such Notes are
concerned except for

     (i) the rights of holders of outstanding Notes to receive payments
  (solely from monies deposited in trust) in respect of the principal of,
  premium, if any, and interest and Liquidated Damages, if any, on such Notes
  when such payments are due,

     (ii) our obligations to issue temporary Notes, register the transfer or
  exchange of any Notes, replace mutilated, destroyed, lost or stolen Notes,
  maintain an office or agency for payments in respect of the Notes and
  segregate and hold such payments in trust,

     (iii) the rights, powers, trusts, duties and immunities of the Trustee
  and

     (iv) the defeasance provisions of the Indenture.

In addition, we may, at our option and at any time, elect to have our
obligations released with respect to certain covenants set forth in the
Indenture, and any omission to comply with such obligations will not constitute
a Default or an Event of Default with respect to the Notes ("covenant
defeasance"). (Sections 1301, 1302, and 1303)

   In order to exercise either defeasance or covenant defeasance,

     (i) we must irrevocably deposit or cause to be deposited with the
  trustee, as trust funds in trust, specifically pledged as security for, and
  dedicated solely to, the benefit of the holders of the Notes, cash in
  United States dollars, U.S. Government Obligations (as defined in the
  Indenture), or a combination thereof, in such amounts as will be
  sufficient, in the opinion of a nationally recognized firm of independent
  public accountants, to pay and discharge the principal of, premium if any,
  and interest and Liquidated Damages, if any, on the outstanding Notes on
  the Stated Maturity (or upon redemption, if applicable) of such principal,
  premium, if any, or installment of interest;

     (ii) no Default or Event of Default with respect to the Notes will have
  occurred and be continuing on the date of such deposit or, insofar as an
  event of bankruptcy under clauses (h) or (i) of "Events of Default" above
  is concerned, at any time during the period ending on the 123rd day after
  the date of such deposit;

     (iii) such defeasance or covenant defeasance will not result in a breach
  or violation of, or constitute a default under any material agreement or
  instrument (other than the Indenture) to which we are a party or by which
  we are bound;

     (iv) in the case of defeasance, we shall have delivered to the trustee
  an opinion of counsel stating that we have received from, or there has been
  published by, the Internal Revenue Service a ruling, or since January 29,
  1999, there has been a change in applicable federal income tax law, in
  either case to the effect that, and based thereon such opinion shall
  confirm that, the holders of the outstanding Notes will not recognize
  income, gain or loss for federal income tax purposes as a result of such
  defeasance and will be subject to federal income tax on the same amounts,
  in the same manner and at the same times as would have been the case if
  such defeasance had not occurred;

     (v) in the case of covenant defeasance, we shall have delivered to the
  trustee an opinion of counsel to the effect that the holders of the Notes
  outstanding will not recognize income, gain or loss for federal income tax
  purposes as a result of such covenant defeasance and will be subject to
  federal income tax on the same amounts, in the same manner and at the same
  times as would have been the case if such covenant defeasance had not
  occurred; and

     (vi) we shall have delivered to the trustee an officer's certificate and
  an opinion of counsel, each stating that all conditions precedent provided
  for relating to either the defeasance or the covenant defeasance, as the
  case may be, have been complied with. (Section 1304)

<PAGE>

Modification and Waiver

   Modifications and amendments of the indenture may be made by us and the
trustee with the consent of the holders of not less than a majority in
aggregate principal amount of the outstanding Notes; provided, however, that no
such modification or amendment may, without the consent of each holder affected
thereby,

     (i) change the Stated Maturity of the principal of, or any installment
  of interest on, any Note,

     (ii) reduce the principal amount of, or premium or Liquidated Damages,
  if any, or interest on any Note or extend the time for payment of interest
  on, or alter the redemption provisions of, any Note,

     (iii) change the currency of payment of principal of, or premium if any,
  or interest on any Note,

     (iv) impair the right of any holder of the Notes to receive payment of,
  principal of and interest on such holder's Notes on or after the due dates
  therefor or to institute suit for the enforcement of any payment on or
  after the Stated Maturity (or, in the case of a redemption, on or after the
  Redemption Date) of any Note,

     (v) reduce the above-stated percentage of outstanding Notes the consent
  of whose holders is necessary to modify or amend the Indenture,

     (vi) modify any provision of any Guarantee of the Notes in a manner
  adverse to the holders of the Notes,

     (vii) waive a default in the payment of principal of, premium, if any,
  or accrued and unpaid interest or liquidated damages, if any, on the Notes
  or

     (viii) reduce the percentage or aggregate principal amount of
  outstanding Notes the consent of whose holders is necessary for waiver of
  compliance with certain provisions of the indenture or for waiver of
  certain defaults.

Governing Law and Submission to Jurisdiction

   The Notes and the indenture will be governed by the laws of the State of New
York. We and the trustee will submit to the jurisdiction of the U.S. federal
and New York state courts located in the Borough of Manhattan, City and State
of New York for purposes of all legal actions and proceedings instituted in
connection with the Notes and the indenture.

Currency Indemnity

   U.S. dollars are the sole currency of account and payment for all sums
payable by us under or in connection with the Notes, including damages. Any
amount received or recovered in a currency other than dollars (whether as a
result of, or of the enforcement of, a judgment or order of a court of any
jurisdiction, in our winding-up or dissolution or otherwise) by any holder of a
Note in respect of any sum expressed to be due to it from us shall only
constitute a discharge to us to the extent of the dollar amount which the
recipient is able to purchase with the amount so received or recovered in that
other currency on the date of that receipt or recovery (or, if it is not
practicable to make that purchase on that date, on the first date on which it
is practicable to do so). If that dollar amount is less than the dollar amount
expressed to be due to the recipient under any Note, we shall indemnify the
recipient against any loss sustained by it as a result. In any event, we shall
indemnify the recipient against the cost of making any such purchase. For the
purposes of this paragraph, it will be sufficient for the holder of a Note to
certify in a satisfactory manner (indicating the sources of information used)
that it would have suffered a loss had an actual purchase of dollars been made
with the amount so received in that other currency on the date of receipt or
recovery (or, if a purchase of dollars on such date had not been practicable,
on the first date on which it would have been practicable, it being required
that the need for a change of date be certified in the manner mentioned above).
These indemnities constitute a separate and independent obligation from our
other obligations, shall give rise to a separate and independent cause of
action, shall apply irrespective of any indulgence granted by any holder of a
Note and shall continue in full force and effect despite any other judgment,
order, claim or proof for a liquidated amount in respect of any sum due under
any Note.

Concerning the Trustee

   The indenture contains certain limitations on the rights of the trustee,
should it become a creditor of us, to obtain payment of claims in certain cases
or to realize on certain property received in respect of any such claim as
security or otherwise. The trustee will be permitted to engage in other
transactions; however, if the trustee acquires any conflicting interest, it
must eliminate such conflict within 90 days, apply to the Securities and
Exchange Commission for permission to continue or resign.

   The holders of a majority in principal amount of the outstanding Notes will
have the right to direct the time, method and place of conducting any
proceeding for exercising any remedy available to the trustee, subject to
certain exceptions. The indenture provides that in case an Event of Default
shall occur (which shall not be cured), the trustee will be required, in the
exercise of its power, to use the degree of care of a prudent man in the
conduct of his own affairs. Subject to such provisions, the trustee will be
under no obligation to exercise any of its rights or powers under the indenture
at the request of any holder of Notes, unless such holder shall have offered to
the trustee security and indemnity satisfactory to it against any loss,
liability or expense.

Book Entry, Delivery and Form

   The initial notes were offered and sold to qualified institutional buyers
("Qualified Institutional Buyers") in reliance on Rule 144A and, to certain
non-U.S. holders, Regulation S under the Securities Act of 1933. The Initial
Notes were issued in registered, global form in minimum denominations of $1,000
in excess thereof.

   The initial notes are represented by one or more permanent global notes in
registered, global form without interest coupons (collectively, the "Rule 144A
Global Note"), and, except as set forth below, the new notes will be
represented by one or more Notes in registered, global form without interest
coupons (the "Unrestricted Global Note," and together with the Rule 144A Global
Note, the "Global Note"). The Rule 144A Global Note was, and the Unrestricted
Global Note will be deposited upon issuance with the trustee as custodian for
the Depositary Trust Company (the "Depositary") in New York, New York, and
registered in the name of the Depositary or its nominee, in each case for
credit to an account of a direct or indirect participant as described below.

   Except as set forth below, the Global Notes may be transferred, in whole and
not in part, only to the Depositary, a nominee of the Depositary or to a
successor of the Depositary or its nominee. Beneficial interests in the Global
Notes may not be exchanged for Notes in certificated form except in the limited
circumstances described below. See "--Depositary Procedures--Exchange of Book-
Entry Notes for Certificated Notes."

   The Trustee will act as registrar.

Depositary Procedures

   The depositary has advised us that the depositary is a limited-purpose trust
company created to hold securities for its participating organizations
(collectively, the "Participants") and to facilitate the clearance and
settlement of transactions in those securities between Participants through
electronic book-entry changes in

                                      131
<PAGE>

accounts of Participants. The Participants include securities brokers and
dealers (including the initial purchasers), banks, trust companies, clearing
corporations and certain other organizations. Access to the depositary's system
is also available to other entities such as banks, brokers, dealers and trust
companies that clear through or maintain a custodial relationship with a
Participant, either directly or indirectly (collectively, "Indirect
Participants"). Persons who are not Participants may beneficially own
securities held by or on behalf of the Depositary only through Participants or
Indirect Participants. The ownership interest and transfer of ownership
interest of each actual purchaser of each security held by or on behalf of the
depositary are recorded on the records of the Participants and Indirect
Participants.

   The depositary has also advised us that pursuant to procedures established
by it, (i) upon deposit of the Global Notes, the depositary will credit the
accounts of Participants designated by the initial purchasers with portions of
the principal amount of Global Notes and (ii) ownership of such interests in
the Global Notes will be shown on, and the transfer of ownership thereof will
be effected only through, records maintained by the Depositary (with respect to
Participants) or by Participants and the Indirect Participants (with respect to
other owners of beneficial interest in the Global Notes).

   Investors in the Global Note may hold their interests therein directly
through the depositary, if they are participants in such system, or indirectly
through organizations that are Participants in such system. All interests in a
Global Note may be subject to the procedures and requirements of the
Depositary.

   The laws of some states require that certain persons take physical delivery
in definitive form of securities that they own. Consequently, the ability to
transfer beneficial interest in a Global Note to such persons may be limited to
that extent. Because the depositary can act only on behalf of Participants,
which in turn act on behalf of Indirect Participants and certain banks, the
ability of a person having a beneficial interest in a Global Note to pledge
such interest to persons or entities that do not participate in the Depositary
system, or otherwise take actions in respect of such interests may be affected
by the lack of physical certificate evidencing such interests.

   Except as described below, owners of interests in the Global Notes will not
have Notes registered in their names, will not receive physical delivery of
Notes in certificated form and will not be considered the registered owners or
holders thereof under the Indenture for any purpose.

   Payments in respect of the principal and premium and liquidated damages, if
any, and interest on a Global Note registered in the name of the Depositary or
its nominee will be payable by the paying agent to the depositary or its
nominee in is capacity as the registered holder of a Global Note under the
indenture. Under the terms of the indenture, we and the trustee will treat the
persons in whose names the Notes, including the Global Notes, are registered as
the owners thereof for the purpose of receiving such payments and for any and
all other purposes whatsoever. Consequently, neither we, the trustee nor any
agent of us or the trustee have or will have any responsibility or liability
for (i) any aspect of the depositary's records or any participant's or Indirect
Participant's records relating to or payments made on account of beneficial
ownership interests in the Global Notes, or for maintaining, supervising or
reviewing any of the Depositary's records or any participant's or Indirect
Participant's records relating to the beneficial ownership interests in the
Global Notes or (ii) any other matter relating to the actions and practices of
the Depositary or any of its Participants or Indirect Participants.

   The depositary has advised us that its current practices, upon receipt of
any payment in respect of securities such as the Notes (including principal and
interest), is to credit the accounts of the relevant Participants with the
payment on the payment date, in amounts proportionate to their respective
holdings in principal amount of beneficial interests in the relevant security
such as the Global Notes as shown on the records of the depositary. Payments by
Participants and the Indirect Participants to the beneficial owners of Notes
will be governed by standing instructions and customary practices and will not
be the responsibility of the depositary, the trustee or us. Neither we nor the
trustee will be liable for any delay by the depositary or its Participants in
identifying the beneficial owners of the Notes, and we and the trustee may
conclusively rely on

                                      132
<PAGE>

and will be protected in relying on instructions from the depositary or its
nominee as the registered owner of the Notes for all purposes.

   Interests in the Global Notes will trade in the depositary's Same-Day Funds
Settlement System and secondary market trading activity in such interests
will, therefore, settle in immediately available funds, subject in all cases
to the rules and procedures of the depositary and its Participants. Transfers
between Participants in the depositary will be effective in accordance with
the depositary's procedures, and will be settled in same-day funds.

   The depositary has advised us that it will take any action permitted to be
taken by a holder of Notes only at the direction of one or more Participants
to whose account the depositary interests in the Global Notes are credited and
only in respect of such portion of the aggregate principal amount of the Notes
as to which such Participant or Participants has or have given direction.
However, if there is an Event of Default under the Notes, the depositary
reserves the right to exchange Global Notes for legended Notes in certificated
form, and to distribute such Notes to its Participants.

   The information in this section concerning the depositary and its book-
entry systems has been obtained from sources that we believe to be reliable,
but we take no responsibility for the accuracy thereof. Neither we nor the
trustee will have any responsibility for the performance by the depositary or
its respective Participants or Indirect Participants of its respective
obligations under the rules and procedures governing its operations.

 Exchange of Book-Entry Notes for Certificated Notes.

   A Global Note is exchangeable for definitive Notes in registered
certificated form if:

     (i) the Depositary

       (A) notifies us that it is unwilling or unable to continue as
    depository for the Global Note and we thereupon fail to appoint a
    successor depository or

       (B) has ceased to be a clearing agency registered under the
    Securities Exchange Act of 1934,

     (ii) upon the continuance of an Event of Default or

     (iii) we, at our option, notify the Trustee in writing that we elect to
  cause issuance of the Notes in certificated form.

In addition, beneficial interests in a Global Note may be exchanged for
certificated Notes upon request but only upon at least 20 days' prior written
notice given to the Trustee by or on behalf of the Depositary in accordance
with customary procedures. In all cases, certificated Notes delivered in
exchange for any Global Note or beneficial interest therein will be registered
in names, and issued in any approved denominations, requested by or on behalf
of the Depositary (in accordance with its customary procedures) and will bear,
the restrictive legend referred to in "Notice to Investors," unless we
determine otherwise in compliance with applicable law.

 Year 2000 Issues.

   Management of the Depositary is aware that some computer applications,
systems, and the like for processing data ("Systems") that are dependent upon
calendar dates, including dates before, on, and after January 1, 2000, may
encounter "Year 2000 problems." The depositary has informed its Participants
and other members of the financial community (the "Industry") that it has
developed and is implementing a program so that its Systems, as the same
relate to the timely payment of distributions (including principal and income
payments) to securityholders, book-entry deliveries, and settlement of trades
within the depositary ("DTC Services"), continue to function appropriately.
This program includes a technical assessment and a remediation plan, each of
which is complete. Additionally, the depositary's plan includes a testing
phase, which is expected to be completed within appropriate time frames.


                                      133
<PAGE>

   However, the depositary's ability to perform properly its services is also
dependent upon other parties, including but not limited to issuers and their
agents, as well as third party vendors from whom DTC licenses software and
hardware, and third party vendors on whom the Depositary relies for information
or the provision of services, including telecommunication and electrical
utility service providers, among others. The depositary has informed the
Industry that it is contacting (and will continue to contact) third party
vendors from whom the Depositary acquires services to: (i) impress upon them
the importance of such services being Year 2000 compliant; and (ii) determine
the extent of their efforts for Year 2000 remediation (and, as appropriate,
testing) of their services. In addition, the depositary is in the process of
developing such contingency plans as it deems appropriate.

   According to the Depositary, the foregoing information with respect to the
Depositary has been provided to the Industry for informational purposes only
and is not intended to serve as a representation, warranty, or contract
modification of any kind.

 Same Day Settlement and Payment.

   The indenture will require that payments in respect of the Notes represented
by the Global Note (including principal, premium, if any, interest and
Liquidated Damages, if any) be made by wire transfer of immediately available
funds to the accounts specified by the Global Note Holder. With respect to
certificated Notes, we will make all payments of principal, premium, if any,
interest and Liquidated Damages, if any, by wire transfer of immediately
available funds to the accounts specified by the holders thereof or, if no such
account is specified, by mailing a check to each such holder's registered
address. We expect that secondary trading in the certificated Notes will also
be settled in immediately available funds.

Exchange Offer and Registration Rights

   Primus and certain subsidiaries entered into the Registration Rights
Agreement with the initial purchasers, pursuant to which we agreed to file with
the Securities Exchange Commission, subject to the provisions described below,
the Exchange Offer Registration Statement on an appropriate form permitting
registration of the new notes to be offered in exchange for the Transfer
Restricted Securities and to permit resales of new notes held by broker-dealers
as contemplated by the Registration Rights Agreement. The Registration Rights
Agreement provides that unless the exchange offer would not be permitted by
applicable law or Securities Exchange Commission policy, we will (i) file the
Exchange Offer Registration Statement with the Commission and use our
reasonable best efforts to cause the Exchange Offer Registration Statement to
be declared effective by the Commission within 150 days after the Closing Date,
(ii) (A) file all pre-effective amendments to such Registration Statement as
may be necessary in order to cause such Registration Statement to become
effective, (B) file if applicable, a post-effective amendment to such
Registration Statement pursuant to Rule 430A under the Securities Act of 1933
and (C) cause all necessary filing in connection with the registration and
qualifications of the new notes to be made under the blue sky laws of such
jurisdictions as are necessary to permit consummation of the exchange offer and
(iii) use our reasonable best efforts to cause the exchange offer to be
consummated on or prior to 180 days after the Closing Date.

   For purposes of the foregoing, "Transfer Restricted Securities" means each
Note until the earliest to occur of

     (i) the date on which such Note has been exchanged by a person other
  than a broker-dealer for new notes in the exchange offer,

     (ii) following the exchange by a broker-dealer in the exchange offer of
  such Note for one or more new notes, the date on which such new notes are
  sold to a purchaser who receives from such broker-dealer on or prior to the
  date of such sale a copy of the prospectus contained in the Exchange Offer
  Registration Statement,

     (iii) the date on which such Note has been effectively registered under
  the Securities Act of 1934 and disposed of in accordance with the Shelf
  Registration Statement or

                                      134
<PAGE>

     (iv) the date on which such Note is eligible for distribution to the
  public pursuant to Rule 144 under the Securities Act.

   Under existing Commission interpretations, the new notes would, in general,
be freely transferable after the exchange offer without further registration
under the Securities Act; provided, however, that, in the case of broker-
dealers participating in the exchange offer, a prospectus meeting the
requirements of the Securities Act must be delivered by such broker-dealers in
connection with resales of the new notes. We have agreed, for a period of 180
days after consummation of the exchange offer, to make available a prospectus
meeting the requirements of the Securities Act to any such broker-dealer for
use in connection with any resale of any new notes acquired in the exchange
offer. A broker-dealer that delivers such a prospectus to purchasers in
connection with such resales will be subject to certain of the civil liability
provisions under the Securities Act and will be bound by the provisions of the
Registration Rights Agreement (including certain indemnification rights and
obligations).

   Holders of Notes that desire to exchange such Notes for new notes in the
exchange offer will be required to make certain representations, including
representations that:

     (i) any new notes to be received by it will be acquired in the ordinary
  course of its business,

     (ii) it has no arrangement with any person to participate in the
  distribution (within the meaning of the Securities Act) of the new notes
  and

     (iii) it is not our "affiliate," as defined in Rule 405 of the
  Securities Act, or if it is an affiliate, it will comply with the
  registration and prospectus delivery requirements of the Securities Act to
  the extent applicable.

   If the holder is not a broker-dealer, it will be required to represent that
it is not engaged in, and does not intend to engage in, the distribution of
the new notes. If the holder is a broker-dealer that will receive new notes
for its own account in exchange for Notes that were acquired as a result of
market-making activities or other trading activities, it will be required to
acknowledge that it will deliver a prospectus in connection with any resale of
such new notes.

   We have agreed to pay all expenses incident to the exchange offer and will
indemnify the initial purchasers against certain liabilities, including
liabilities under the Securities Act.

   If:

     (i) we are not permitted to file the exchange offer Registration
  Statement or to consummate the exchange offer because the exchange offer is
  not permitted by applicable law or Commission policy,

     (ii) any holder of Transfer Restricted Securities that is a "qualified
  institutional buyer" (as defined in Rule 144A under the Securities Act)
  notifies the Company at least 20 business days prior to the consummation of
  the exchange offer that

       (a) applicable law or Commission policy prohibits us from
    participating in the Exchange Offer,

       (b) such Holder may not resell the new notes acquired by it in the
    exchange offer to the public without delivering a prospectus and the
    prospectus contained in the Exchange Offer Registration Statement is not
    appropriate or available for such resales by such holder or

       (c) such holder is a broker-dealer and holds Notes acquired directly
    from us or an affiliate of ours,

     (iii) the exchange offer is not for any other reason consummated by July
  28, 1999 or

     (iv) the exchange offer has been completed and in the written opinion of
  counsel for the initial purchasers a Registration Statement must be filed
  and a prospectus must be delivered by the initial purchasers in connection
  with any offering or sale of Transfer Restricted Securities, we will use
  our reasonable best efforts to:

                                      135
<PAGE>

       (A) file a Shelf Registration Statement within 60 days of the
    earliest to occur of (i) through (iv) above and

       (B) cause the Shelf Registration Statement to be declared effective
    by the Commission on or prior to the 120th day after such obligation
    arises.

We shall use our reasonable best efforts to keep such Shelf Registration
Statement continuously effective, supplemented and amended to ensure that it is
available for resales of Notes by the holders of Transfer Restricted Securities
entitled to this benefit and to ensure that such Shelf Registration Statement
conforms and continues to conform with the requirements of the Registration
Rights Agreement, the Securities Act and the policies, rules and regulations of
the Commission, as announced from time to time, until the second anniversary of
the Closing Date; provided, however, that during such two-year period the
holders may be prevented or restricted by us from effecting sales pursuant to
the Shelf Registration Statement as more fully described in the Registration
Rights Agreement. A holder of Notes that sells its Notes pursuant to the Shelf
Registration Statement generally will be required to be named as a selling
security holder in the related prospectus and to deliver a prospectus to
purchasers, will be subject to certain of the civil liability provisions under
the Securities Act in connection with such sales and will be bound by the
provisions of the Registration Rights Agreement that are applicable to such
holder (including certain indemnification and contribution obligations).

   If:

     (i) we fail to file with the Commission the Shelf Registration Statement
  on or before the date specified therein for such filing,

     (ii) any of such Registration Statements is not declared effective by
  the Commission on or prior to the date specified for such effectiveness in
  the Registration Rights Agreement (the Effectiveness Target Date),

     (iii) the exchange offer has not been consummated within 180 days after
  the Closing Date with respect to the Exchange Offer Registration Statement,
  or

     (iv) any Registration Statement required by the Registration Rights
  Agreement is filed and declared effective but thereafter ceases to be
  effective or fails to be usable for its intended purpose without being
  succeeded within five business days by a post-effective amendment to such
  Registration Statement that cures such failure and that is itself
  immediately declared effective (each such event referred to in clauses (i)
  through (iv) above, a Registration Default),

then additional cash interest (Liquidated Damages) shall accrue to each holder
of the Notes commencing upon the occurrence of such Registration Default in an
amount equal to .50% per annum of the principal amount of Notes held by such
Holder. The amount of liquidated damages will increase by an additional .50%
per annum of the principal amount of Notes with respect to each subsequent 90-
day period (or portion thereof) until all Registration Defaults have been
cured, up to a maximum rate of liquidated damages of 1.50% per annum of the
principal amount of Notes. All accrued liquidated damages will be paid to
holders by us in the same manner as interest is paid pursuant to the indenture.
Following the cure of all Registration Defaults relating to any particular
Transfer Restricted Securities, the accrual of Liquidated Damages with respect
to such Transfer Restricted Securities will cease.

   As a result of the exchange offer not having been consummated by July 28,
1999, a Registration Default commenced on July 29, 1999 and Liquidated Damages
began to accrue to each holder of the Notes in the amount set forth in the
preceding paragraph.

   The summary herein of certain provisions of the Registration Rights
Agreement does not purport to be complete and is subject to, and is qualified
in its entirety by reference to, all the provisions of the Registration Rights
Agreement, a copy of which will be made available to prospective purchasers of
the Notes upon request to us.

                       FEDERAL INCOME TAX CONSIDERATIONS

   The following is a general discussion of certain material United States
federal income tax consequences of the exchange of the initial notes for the
new notes, and the ownership and disposition of the new notes for holders who
acquired the new notes in exchange for existing notes. This discussion is
limited to holders who hold both the existing notes and the new notes as
capital assets, within the meaning of Section 1221 of the Internal Revenue Code
of 1986, as amended.

   This discussion does not address all aspects of United States federal income
taxation that may be applicable to investors in light of their particular
circumstances, or to investors subject to special treatment under United States
federal income tax law (including, without limitation, certain financial
institutions, insurance companies, tax-exempt entities, dealers in securities,
persons who have acquired notes as part of a straddle, hedge, conversion
transaction or other integrated investment or constructive sale or persons
whose functional currency is not the United States dollar).

   This discussion is based on provisions of the Code, Treasury regulations
promulgated thereunder, and administrative and judicial interpretations
thereof, all as in effect on the date hereof and all of which are subject to
change, possibly with retroactive effect.

   EACH PROSPECTIVE INVESTOR SHOULD CONSULT ITS TAX ADVISOR AS TO THE
PARTICULAR TAX CONSEQUENCES TO SUCH INVESTOR OF THE PURCHASE, OWNERSHIP AND
DISPOSITION OF THE NOTES INCLUDING THE APPLICABILITY OF ANY FEDERAL ESTATE OR
GIFT TAX LAWS, ANY STATE, LOCAL OR FOREIGN TAX LAWS, ANY CHANGES IN APPLICABLE
TAX LAWS AND ANY PENDING OR PROPOSED LEGISLATION OR REGULATIONS.

   As used in this section, the term "U.S. holder" means a beneficial owner of
a Note that is, for United States federal income tax purposes,

  .  a citizen or resident of the United States,

  .  a corporation or partnership created or organized under the laws of the
     United States or of any political subdivision thereof,

  .  an estate the income of which is subject to United States federal income
     taxation regardless of its source, or

  .  a trust, if a United States court is able to exercise primary
     supervision over the administration of such trust and one or more United
     States persons have the authority to control all substantial decisions
     of such trust or the trust has a valid election in effect under
     applicable U.S. Treasury regulations to be treated as a U.S. person.

   The term "non-U.S. holder" means a beneficial owner of a Note other than a
U.S. Holder.

U.S. Taxation of U.S. Holders

   Payments of Interest. Stated interest payable on the new notes generally
will be included in the gross income of a U.S. holder as ordinary interest
income at the time accrued or received, in accordance with such U.S. holder's
method of accounting for United States federal income tax purposes.

   We may be required to pay liquidation damages to U.S. holders of the new
notes. Although the matter is not free from doubt, we intend to take the
position that a U.S. holder of a new note should be required to report the
liquidated damages as ordinary income for United States federal income tax
purposes when the liquidated damages accrue or are received in accordance with
the holder's method of accounting. It is possible, however, that the Internal
Revenue Service may take a different position, in which case the timing and
amount of income may be different.


                                      137
<PAGE>

   Disposition of the Notes. The exchange of the existing notes for the new
notes will not be a taxable event for U.S. federal income tax purposes. The
holding period of the new note will include the U.S. holder's holding period of
the initial note, and the basis of the new note will be the same as the basis
in the initial note immediately before the exchange.

   On the sale, exchange, redemption, retirement at maturity or other
disposition of a new note, a U.S. holder generally will recognize capital gain
or loss (except ans noted in the next paragraph) equal to the difference
between the amount realized and the U.S. holder's adjusted tax basis in the new
note. The capital gain or loss will be long-term capital gain or loss if the
holding period for the new note (that includes the holding period for the
initial note) exceeds one year at the time of the disposition. Generally, the
maximum tax rate for individuals on long term capital gain is 20%.

   To the extent a portion of the amount realized on the disposition of the new
note is attributable to interest, it will be taxed as ordinary income and not
capital gain. A portion of the amount realized will be attributable to interest
if there is accrued but unpaid interest at the time of the disposition, or if
the U.S. holder purchased the initial notes (other than at original issuance)
at a market discount, as defined in the Internal Revenue Code of 1986, as
amended. If a U.S. holder bought an existing note for an amount less than the
stated redemption price at maturity, he or she should consult with his or her
tax advisor to determine if there is market discount in the new note, and the
impact of the market discount on the taxation of the holding and disposition of
the new note.

 Bond Premium

   If a U.S. holder purchased an initial note for an amount in excess of the
amount payable at the maturity date, the U.S. holder may deduct the excess as
amortizable bond premium over the aggregate terms of the existing notes and the
new notes under a yield to maturity formula. The deduction is available only if
an election is made by the U.S. holder, and the election will apply to all
obligations owned or acquired by the U.S. holder. The U.S. holder's adjusted
basis in the initial notes and the new notes will be reduced to the extent of
the amortizable bond premium.

U.S. Taxation of Non-U.S. Holders

   Payments of Interest. In general, under current U.S. tax law, payments of
interest received by a non-U.S. holder will not be subject to United States
withholding tax, provided that the non-U.S. holder

  .  does not actually or constructively own 10% or more of the total
     combined voting power of all of our classes of stock entitled to vote,

  .  is not a bank whose receipt of interest is described in Section
     881(c)(3)(A) of the Internal Revenue Code,

  .  is not a controlled foreign corporation that is related to us actually
     or constructively through stock ownership, and

  .  either

    .  the beneficial owner of the new note provides us or our paying agent
       with a properly executed certification on IRS form W-8BEN (or
       suitable substitute form), signed under penalties of perjury, that
       the beneficial owner is not a "U.S. person" for U.S. federal income
       tax purposes and that provides the beneficial owner's name and
       address, or

    .  a securities clearing organization, bank or other financial
       institution that holds customers' securities in the ordinary course
       of its business holds the new note and certifies to us or our agent
       under penalties of perjury that the IRS form W-8BEN (or a suitable
       substitute form) has been received from the beneficial owner of the
       new note or a qualifying intermediary and furnishes the payor a copy
       thereof.

   Payments of interest not exempt from U.S. federal withholding tax as
described above, or not exempt because of a change of law effective after the
date of the original issuance of the existing note, will be subject to such
withholding tax at the rate of 30%, unless reduced or eliminated under an
applicable income tax treaty,

                                      138
<PAGE>

and unless the beneficial owner of the new note provides us or our paying
agent, as the case may be, with a properly executed

  .  IRS Form W-8BEN (or successor form) claiming an exemption from or
     reduction of withholding under the benefit of a tax treaty or

  .  IRS Form W-8ECI (or successor form) stating that interest paid on the
     new note is not subject to withholding tax because it is effectively
     connected with the beneficial owner's conduct of a trade or business in
     the United States.

   It is unclear whether the payment of liquidated damages to a non-U.S. holder
will be subject to withholding of U.S. federal income tax, and we may withhold
30% from any such payments made to non-U.S. holders.

   Treasury regulations that are to be effective with respect to payments made
after December 31, 2001 provide alternative methods for satisfying the
certification requirements described in the preceding paragraph. Those
regulations also will require, in the case of new notes held by a foreign
partnership, that the certification described above be provided by each
partner.

 Disposition of the New Notes.

   The exchange of an initial note for a new note will not be a taxable event
for a non-U.S. holder.

   A non-U.S. holder generally will not be subject to U.S. federal income tax
(and no tax will be withheld) with respect to gain realized on the sale,
exchange or other disposition of a new note, unless

  .  the gain is effectively connected with a U.S. trade or business
     conducted by the non-U.S. holder or

  .  the non-U.S. holder is an individual who is present in the United States
     for 183 or more days during the taxable year of the Disposition and
     certain other conditions are met.

   Effectively Connected Income. If interest and other payments received by a
non-U.S. holder with respect to the new notes, including proceeds from the sale
or exchange of the new notes, are effectively connected with the conduct by the
non-U.S. holder of a trade or business within the United States (or the non-
U.S. holder is otherwise subject to U.S. federal income taxation on a net basis
with respect to such holder's ownership of the notes), the non-U.S. holder will
generally be subject to the rules described above under "U.S. Taxation of U.S.
Holders" (subject to any modification provided under an applicable income tax
treaty). The non-U.S. holder may also be subject to the U.S. "branch profits
tax" if the holder is a corporation.

Backup Withholding and Information Reporting

   In general, information reporting requirements will apply to certain
payments of principal, interest and liquidated damages paid on new notes and to
the proceeds of sale of a new note made to U.S. holders other than certain
exempt recipients (such as corporations). U.S. holders also may be subject to
backup withholding at a rate of 31% on payments of principal, liquidated
damages and interest on, and the proceeds of the sale or exchange of, the new
notes. In general, backup withholding will apply to the payments if the U.S.
holder

  .  fails to furnish a taxpayer identification number (TIN) which, for an
     individual, would be his or her Social Security number,

  .  furnishes an incorrect TIN, or

  .  fails to report in full payments of interest or dividends.

   Information reporting and backup withholding generally will not apply to
payments made to a non-U.S. holder who provides the certification described
under "U.S. Taxation of non-U.S. holders--Payments of Interest" or otherwise
establishes an exemption from backup withholding, provided that neither we or
the paying agent have actual knowledge that the holder is a U.S. person.

                              PLAN OF DISTRIBUTION

   Each broker-dealer that holds initial notes that were acquired for its own
account as a result of market making or other trading activities (other than
initial notes acquired directly from us), may exchange initial notes for new
notes in the exchange offer. However, any such broker-dealer may be deemed to
be an "underwriter" within the meaning of such term under the Securities Act
and must, therefore, acknowledge that it will deliver a prospectus in
connection with any resale of new notes received in the exchange offer. This
prospectus delivery requirement may be satisfied by the delivery by such
broker-dealer of this prospectus, as it may be amended or supplemented from
time to time. We have agreed that, for a period of 180 days after the effective
date of this Prospectus, we will make this Prospectus, as amended or
supplemented, available to any broker-dealer who receives new notes in the
exchange offer for use in connection with any such sale. We will not receive
any proceeds from any sales of new notes by broker-dealers. new notes received
by broker-dealers for their own accounts pursuant to the exchange offer may be
sold from time to time in one or more transactions in the over-the-counter
market, in negotiated transactions, through the writing of options on the new
notes or a combination of such methods of resale, at market prices at the time
of resale, at prices related to such prevailing market prices or negotiated
prices. Any such resale of new notes by broker-dealers may be made directly to
a purchaser or to or through brokers or dealers who may receive compensation in
the form of commissions or concessions from any such broker-dealer and/or the
purchasers of any such new notes. Any broker-dealer that resells new notes that
were received by it for its own account pursuant to the exchange offer and any
broker or dealer that participates in a distribution of such new notes may be
deemed to be an "underwriter" within the meaning of the Securities Act and any
profit on any such resale of new notes and any commissions or concessions
received by any such persons may be deemed to be underwriting compensation
under the Securities Act. We have agreed to pay all expenses incident to the
exchange offer other than commissions or concessions of any brokers or dealers
and will indemnify holders (including any broker-dealer) against certain
liabilities, including liabilities under the Securities Act. By acceptance of
the exchange offer, each broker-dealer that receives new notes pursuant to the
exchange offer hereby agrees to notify us prior to using the Prospectus in
connection with the sale or transfer of new notes, and acknowledges and agrees
that, upon receipt of notice from us of the happening of any event which makes
any statement in the Prospectus untrue in any material respect or which
requires the making of any changes in the prospectus in order to make the
statements herein not misleading (which notice we agree to deliver promptly to
such broker-dealer), such broker- dealer will suspend use of the prospectus
until we have amended or supplemented the prospectus to correct such
misstatement or omission and has furnished copies of the amended or
supplemented prospectus to such broker-dealer.

   The report of KPMG LLP covering the December 31, 1998 combined financial
statements, contains an explanatory paragraph that states that the Company has
filed for protection under Chapter 11 of the United States Bankruptcy Code due
to significant financial and liquidity problems. These circumstances raise
substantial doubt about its ability to continue as a going concern. The
combined financial statements do not include any adjustments that might result
from the outcome of this uncertainty.

                          INDEPENDENT AUDITORS' REPORT

To the Board of Directors and Stockholders of
Primus Telecommunications Group, Incorporated

   We have audited the accompanying consolidated balance sheets of Primus
Telecommunications Group, Incorporated and subsidiaries (the "Company") as of
December 31, 1998 and 1997, and the related consolidated statements of
operations, stockholders' equity, comprehensive loss and cash flows for each of
the three years in the period ended December 31, 1998. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

   We conducted our audits in accordance with generally accepted auditing
standards. 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 audits provide a reasonable basis
for our opinion.

   In our opinion, such consolidated financial statements present fairly, in
all material respects, the financial position of Primus Telecommunications
Group, Incorporated and subsidiaries as of December 31, 1998 and 1997, and the
results of their operations and their cash flows for each of the three years in
the period ended December 31, 1998, in conformity with generally accepted
accounting principles.

                 PRIMUS TELECOMMUNICATIONS GROUP, INCORPORATED

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Organization and Business

   Primus Telecommunications Group, Incorporated (Primus or the Company) is a
facilities-based global telecommunications company that offers international
and domestic long distance, Internet and data, and other telecommunications
services to business, residential and other telecommunications carrier
customers primarily in North America, the Asia-Pacific and Europe. The Company,
incorporated in the state of Delaware, operates as a holding company and has
wholly-owned operating subsidiaries in the United States, Canada, Mexico,
Australia, Japan, the United Kingdom and Germany.

2. Summary of Significant Accounting Policies

   Principles of Consolidation--The consolidated financial statements include
the accounts of the Company and its wholly-owned and majority-owned
subsidiaries. All intercompany accounts and transactions have been eliminated.

   Revenue Recognition--Revenues from long distance telecommunications services
are recognized when the services are provided and are presented net of
estimated uncollectible amounts.

   Cost of Revenue--Cost of revenue includes network costs that consist of
access, transport, and termination costs. Such costs are recognized when
incurred in connection with the provision of telecommunications services.

   Foreign Currency Translation--The assets and liabilities of the Company's
foreign subsidiaries are translated at the exchange rates in effect on the
reporting date, and income and expenses are translated at the average exchange
rate during the period. The net effect of such translation gains and losses are
reflected within accumulated other comprehensive loss in the stockholders'
equity section of the balance sheet.

   Cash and Cash Equivalents--The Company considers cash on hand, deposits in
banks, certificates of deposit, and overnight repurchase agreements with
original maturities of three months or less to be cash and cash equivalents.

   Restricted Investments--Restricted investments consist of United States
Federal Government-backed obligations which are recorded at amortized cost.
These securities are classified as held-to-maturity and are restricted to
satisfy certain interest obligations on the Company's 1997 Senior Notes.

   Property and Equipment--Property and equipment, which consists of fiber
optic cable and telecommunications equipment, furniture and computer equipment,
leasehold improvements and software is stated at cost less accumulated
depreciation and amortization. Depreciation and amortization expense are
computed using the straight-line method over the estimated useful lives of the
assets which range from three to twenty-five years, or for leasehold
improvements and leased equipment, over the terms of the leases or estimated
lives, whichever is shorter. Expenditures for maintenance and repairs that do
not materially extend the useful lives of the assets are charged to expense.

   Intangible Assets--At December 31, 1998 and 1997 intangible assets, net of
accumulated amortization, consist of goodwill of $179.9 million and $27.8
million respectively, and customer lists of $25.1 million and $5.3 million
respectively. Goodwill is being amortized over 30 years on a straight-line
basis and customer lists over the estimated run-off of the customer bases not
to exceed five years. Accumulated amortization at December 31, 1998 and 1997,
was $4.7 million and $1.2 million related to goodwill and $5.9 million and $1.9
million related to customer lists, respectively. The Company periodically
evaluates the realizability of intangible and other long-lived assets. In
making such evaluations, the Company compares certain financial

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

indicators such as expected undiscounted future revenues and cash flows to the
carrying amount of the assets. The Company believes that no impairments exist
as of December 31, 1998.

   Deferred Financing Costs--Deferred financing costs incurred in connection
with the 1998 Senior Notes and the 1997 Senior Notes are reflected within other
assets and are being amortized over the life of the respective Senior Notes
using the straight-line method which does not differ materially from the
effective interest method.

   Stock-Based Compensation--The Company adopted Statement of Financial
Accounting Standards No. 123 (SFAS 123), Accounting for Stock-Based
Compensation. Under the provisions of SFAS 123, the Company continues to
measure compensation expense for its stock-based employee compensation plans
using the intrinsic value method prescribed by Accounting Principles Board
Opinion No. 25, Accounting for Stock Issued to Employees, and has provided in
Note 10 pro forma disclosures of the effect on net loss and loss per share as
if the fair value-based method prescribed by SFAS 123 had been applied in
measuring compensation expense.

   Use of Estimates--The preparation of financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities and
disclosures of contingent assets and liabilities at the date of the financial
statements and the reported amounts of net revenue and expenses during the
reporting period. Actual results could differ from those estimates.

   Concentration of Credit Risk--Financial instruments that potentially subject
the Company to concentration of credit risk principally consist of trade
accounts receivable. The Company performs ongoing credit evaluations of its
customers but generally does not require collateral to support customer
receivables.

   Income Taxes--The Company recognizes income tax expense for financial
reporting purposes following the asset and liability approach for computing
deferred income taxes. Under this method, the deferred tax assets and
liabilities are determined based on the difference between financial reporting
and tax bases of assets and liabilities based on enacted tax rates. Deferred
tax assets are reduced by a valuation allowance when, in the opinion of
management, it is more likely than not that some portion or all of the deferred
tax assets will not be realized.

   Net Loss Per Share--The Company has computed basic and diluted net loss per
share based on the weighted average number of shares of common stock and
potential common stock outstanding during the period. Potential common stock,
for purposes of determining diluted net loss per share, would include, where
applicable, the effects of dilutive stock options, warrants, and convertible
securities, and the effect of such potential common stock would be computed
using the treasury stock method or the if-converted method. None of the
Company's outstanding options and warrants are considered to be dilutive.

   Comprehensive Income (Loss)--In 1998, the Company adopted the provisions of
Statement of Financial Accounting Standards No. 130 (SFAS 130), Reporting
Comprehensive Income. As such, a consolidated statement of comprehensive loss
reflecting the aggregation of net loss and foreign currency translation
adjustments, the Company's principal components of other comprehensive income
or loss, has been presented for each of the three years in the period ended
December 31, 1998.

   Operating Segments--In 1998, the Company adopted the provisions of Statement
of Financial Accounting Standards No. 131 (SFAS 131), Disclosures about
Segments of an Enterprise and Related Information (Note 14). SFAS 131
superceded SFAS 14 and its adoption resulted in revised and additional
disclosures but had no effect on the financial position, results of operations
or liquidity of the Company.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

   New Accounting Pronouncements--In June 1998, Statement of Financial
Accounting Standards No. 133 (SFAS 133), Accounting for Derivative Instruments
and Hedging Activities was issued. SFAS 133 established standards for the
accounting and reporting of derivative instruments and hedging activities and
requires that all derivative financial instruments be measured at fair value
and recognized as assets or liabilities in the financial statements. The
Statement will be adopted by the Company during fiscal 2000, and the Company is
currently evaluating the impact of such adoption.

   In April 1998, the American Institute of Certified Public Accountants
(AICPA) issued Statement of Position (SoP) 98-5, Reporting on the Costs of
Start-Up Activities. SoP 98-5 provides guidance on the financial reporting of
start-up and organizational costs. The effect of adopting SoP 98-5 is not
expected to have a material effect on the financial position, results of
operation or liquidity of the Company.

   Reclassifications--Certain previous year amounts have been reclassified to
conform with current year presentation.

3. Acquisitions

   On June 9, 1998 the Company acquired TresCom International, Inc. (TresCom),
a long distance telecommunications carrier focused on international long
distance traffic originating in the United States and terminating in the
Caribbean and Central and South America regions. As a result of the
acquisition, all of the approximately 12.7 million TresCom common shares
outstanding were exchanged for approximately 7.8 million shares of the
Company's common stock valued at approximately $138 million. An additional
$11.7 million cash purchase obligation associated with a subsidiary of TresCom
is expected to paid during 1999 and has been included in accrued expenses and
other current liabilities.

   In March 1998 the Company purchased a 60% controlling interest in Hotkey
Internet Services Pty., Ltd. (Hotkey), an Australian ISP, for approximately
$1.3 million.

   Effective March 1, 1998 the Company acquired all of the outstanding stock of
Eclipse Telecommunications Pty., Ltd. (Eclipse), a data communications provider
in Australia. The Company paid approximately $1.8 million in cash and 27,500
shares of the Company's Common Stock for Eclipse.

   On October 20, 1997, the Company acquired the equity and ownership interests
in Telepassport L.L.C. (Telepassport) for a purchase price of $6.0 million.
Additionally, on October 20, 1997, the Company purchased substantially all of
the assets of USFI, Inc. (USFI) for $5.5 million. Telepassport and USFI were
under common control and engaged in the business of providing international and
domestic telecommunication services, including long distance and reorigination
services in Europe, Asia, and South Africa.

   On April 8, 1997, the Company acquired the assets of Cam-Net Communications
Network, Inc. and its subsidiaries, a Canadian based provider of domestic and
international long distance service. The purchase price was approximately $5.0
million in cash.

   On March 1, 1996, the Company acquired the outstanding capital stock of
Axicorp Pty., Ltd. (subsequently renamed Primus Australia), the fourth largest
telecommunications carrier in Australia. The purchase price consisted of cash,
Company stock, and seller financing. The Company paid $5.7 million cash,
including transaction costs, and issued 455,000 shares of its Series A
Convertible Preferred Stock, which were subsequently converted to 1,538,355
common shares. The Company also issued two notes aggregating $8.1 million to
the sellers, both of which were repaid in full during 1997.

   As a result of the acquisition of TresCom, the Company has a $25 million
revolving credit and security agreement (the Revolving Credit Agreement) with a
commercial bank secured by certain of the Company's accounts receivable. In
January 1999, the Company voluntarily repaid in full and terminated the
Revolving Credit Agreement.

   On May 19, 1998 the Company completed the sale of $150 million 9 7/8% Senior
Notes (1998 Senior Notes). The 1998 Senior Notes are due May 15, 2008 with
early redemption at the option of the Company at any time after May 15, 2003.
In addition, prior to May 15, 2001, the Company may redeem up to 25% of the
originally issued principal amount of the 1998 Senior Notes at 109.875% of the
principal amount thereof, plus accrued and unpaid interest through the
redemption date. Interest is payable each May 15th and November 15th.

   On August 4, 1997 the Company completed the sale of $225 million 11 3/4%
Senior Notes (1997 Senior Notes) and Warrants (the Offering) to purchase
392,654 shares of the Company's common stock. The 1997 Senior Notes are due
August 1, 2004 with early redemption at the option of the Company at any time
after August 1, 2001, at a premium to par value. Dividends are currently
prohibited by the senior notes indenture. Interest payments are due semi-
annually on February 1st and August 1st. A portion of the proceeds from the
offering of the 1997 Senior Notes have been pledged to secure the first six
semi-annual interest payments on the 1997 Senior Notes and are reflected on the
balance sheet as restricted investments. A portion of the proceeds of the
Offering, $2.535 million, was allocated to the warrants, and the resulting debt
discount is being amortized over the life of the debt on the straight-line
method which does not differ materially from the effective interest method.

   During the year ended December 31, 1998, the valuation allowance increased
by approximately $21.5 million primarily due to the acquisition of TresCom and
its related net operating losses.

   At December 31, 1998, the Company had operating loss carryforwards available
to reduce future federal taxable income which expire as follows (in millions):

</TABLE>

   Approximately $23.7 million of operating loss carryforwards relate to the
acquisition of TresCom. Utilization of these operating losses is limited to the
offset of future TresCom operating income. The Company's net operating loss
carryforwards for state purposes are not significant and, therefore, have not
been recorded as deferred tax assets.

   At December 31, 1998, the Company had Australian and United Kingdom net
operating loss carryforwards of $18.6 million and $2.1 million (in United
States dollars), respectively, that have no expiration periods.

   No provision was made in 1998 for U.S. income taxes on the undistributed
earnings of the foreign subsidiaries as it is the Company's intention to
utilize those earnings in the foreign operations for an indefinite period of
time or to repatriate such earnings only when tax effective to do so. It is not
practicable to determine the amount of income or withholding tax that would be
payable upon the remittance of those earnings.

   The carrying amounts reported in the consolidated balance sheet for cash and
cash equivalents, restricted investments, accounts receivable and accounts
payable approximate fair value. The estimated fair value of the Company's 1998

prices, at December 31, 1998 was $375 million. The estimated fair value of the
Company's 1997 Senior Notes (carrying value of $223 million), based on quoted
market prices, at December 31, 1997 was $242 million.

9. Stockholders' Equity

   In December 1998, the Company adopted a Stockholders' Rights Plan (the
Rights Plan) under which preferred stock purchase rights have been granted to
the Company's common stockholders of record at the close of business on
December 31, 1998. The rights will become exercisable if a person or group
becomes the beneficial owner of more than 20% of the outstanding common stock
of the Company or announces an offer to become the beneficial owner of more
than 20% of the outstanding common stock of the Company.

   In June 1998, the Company issued 7,836,324 shares of its common stock,
valued at $137.6 million, in exchange for all of the outstanding common shares
of TresCom. Additionally, the Board amended the Company's Amended and Restated
Certificate of Incorporation (the Certificate) to increase the authorized
Common Stock to 80,000,000 shares.

   In October 1997, the Company issued 1,842,941 shares of its common stock
pursuant to the exercise of certain warrants, which had been issued in
connection with the Company's $16 million July 1996 private equity sale. In
connection with such exercise, the Company received approximately $1.5 million.

   In August 1997 the Company completed a Senior Notes and Warrants Offering.
Warrants valued at $2,535,000 to purchase 392,654 shares of the Company's
common stock at a price of $9.075 per share were issued.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)


   In November 1996, the Company completed an initial public offering of
5,750,000 shares of its Common Stock. The net proceeds to the Company (after
deducting underwriter discounts and offering expenses) were $54.4 million.

   In connection with the Company's initial public offering, the Board approved
a split of all shares of Common Stock at a ratio of 3.381 to one as of November
7, 1996 and amended the Company's Certificate to increase the authorized Common
Stock to 40,000,000 shares. All share amounts presented have been restated to
give effect to the November 7, 1996 stock split.

   In February 1996, the Company's Certificate was amended to authorize
2,455,000 shares of Preferred Stock (nonvoting) with a par value of $0.01 per
share. On March 1, 1996, 455,000 shares of Series A Convertible Preferred Stock
were issued in connection with the purchase of Primus Australia. The
outstanding Preferred Stock was converted to Common Stock prior to the date of
the Company's initial public offering.

10. Stock-Based Compensation

   In December 1998, the Company established the 1998 Restricted Stock Plan
(the Restricted Plan) to facilitate the grant of restricted stock to selected
individuals who contribute to the development and success of the Company. The
total number of shares of common stock that may be granted under the Restricted
Plan is 750,000. As of December 31, 1998, there had not been any grants under
the Restricted Plan.

   The Company sponsors an Employee Stock Option Plan (the Employee Plan). The
total number of shares of common stock authorized for issuance under the
Employee Plan is 3,690,500. Under the Employee Plan, awards may be granted to
key employees of the Company and its subsidiaries in the form of Incentive
Stock Options or Nonqualified Stock Options. The Employee Plan allows the
granting of options at an exercise price of not less than 100% of the stock's
fair value at the date of grant. The options vest over a period of up to three
years, and no option will be exercisable more than ten years from the date it
is granted.

   The Company sponsors a Director Stock Option Plan (the "Director Plan") for
non-employee directors. Under the Director Plan, an option is granted to each
qualifying non-employee director to purchase 15,000 shares of common stock,
which vests over a two-year period. The option price per share is the fair
market value of a share of common stock on the date the option is granted. No
option will be exercisable more than ten years from the date of grant. An
aggregate of 338,100 shares of common stock were reserved for issuance under
the Director Plan.

   A summary of stock option activity during the three years ended December 31,
1998 is as follows:

11. Employee Benefit Plans

   The Company sponsors a 401(k) employee benefit plan (the 401(k) Plan) that
covers substantially all United States based employees. Employees may
contribute amounts to the 401(k) Plan not to exceed statutory limitations. The
401(k) plan provides an employer matching contribution of 50% of the first 6%
of employee annual salary contributions. The employer match is made in common
stock of the Company and is subject to 3-year cliff vesting. The Company
contributed Primus common stock valued at approximately $119,000 and $45,000
during 1998 and 1997.

   Effective January 1, 1998, the Company adopted an Employee Stock Purchase
Plan (ESPP). The ESPP allows employees to contribute up to 15% of their
compensation to be used toward purchasing the Company's common stock at 85% of
the fair market value. An aggregate of 2,000,000 shares of common stock were
reserved for issuance under the ESPP.

The Company has three reportable operating segments based on management's
organization of the enterprise into geographic areas--North America, Asia-
Pacific and Europe. The Company evaluates the performance of its segments and
allocates resources to them based upon net revenue and EBITDA. The Company
defines EBITDA as net income (loss) before interest expense and interest
income, income taxes, depreciation and amortization and other income (expense).

16. Subsequent Events

   On March 31, 1999, the Company purchased the common stock of London Telecom
Network, Inc. and certain related entities that provide long distance
telecommunications services in Canada (the LTN Companies), for approximately
$36 million in cash (including payments made in exchange for certain non-
competition agreements). In addition, on March 31, 1999, the Company entered
into an agreement to purchase for $14 million in cash substantially all of the
operating assets of Wintel CNC Communications Inc. and Wintel CNT
Communications Inc. (the Wintel Companies), which are Canada-based long
distance telecommunications providers affiliated with the LTN Companies. The
purchase of the assets of the Wintel Companies is expected to close in early
May 1999. If the LTN companies and the Wintel Companies collectively achieve
certain financial goals during the first half of 1999, the Company has agreed
to pay up to an additional $4.6 million in cash.

   In February 1999 the Company purchased the remaining 40% of Hotkey, a
Melbourne, Australia-based ISP. The remaining 40% was purchased for
approximately $1.1 million comprised of $0.3 million in cash and 57,025 shares
of the Company's common stock.

   On February 5, 1999 the Company acquired all of the outstanding shares in
the capital of GlobalServe Communications, Inc., a privately held ISP based in
Toronto, Canada. The purchase price of approximately $4.2 million was comprised
of $2.1 million in cash and 142,806 shares of the Company's common stock.

   On January 29, 1999 the Company completed the sale of $200 million 11 1/4%
Senior Notes (1999 Senior Notes) due 2009 with semi-annual interest payments.
The $192.5 million in net proceeds of the 1999 Senior Notes will be used to
fund capital expenditures to expand and develop the Company's global Network
and other corporate purposes.

                         REPORT OF INDEPENDENT AUDITORS

The Board of Directors
TresCom International, Inc.

   We have audited the accompanying consolidated balance sheets of TresCom
International, Inc. and its subsidiaries ("TresCom") as of December 31, 1997
and 1996 and the related consolidated statements of operations, shareholders'
equity and cash flows for each of the three years in the period ended December
31, 1997. These financial statements are the responsibility of TresCom's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.

   We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audits 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 audits provide a reasonable basis
for our opinion.

   In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of TresCom
International, Inc. and subsidiaries at December 31, 1997 and 1996 and the
results of their operations and their cash flows for each of the three years in
the period ended December 31, 1997, in conformity with generally accepted
accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                (IN THOUSANDS, EXCEPT SHARE AND PER SHARE DATA)

1. BUSINESS

 Organization and Basis of Presentation

   TresCom International, Inc. (TresCom) was incorporated in Florida on
December 8, 1993 as TeraCom Communications, Inc. Effective June 30, 1994,
TresCom changed its name to TresCom International, Inc.

   TresCom is a facilities-based long-distance telecommunications carrier
focused on international long- distance traffic. TresCom offers
telecommunications services, including direct dial "1 plus" and toll-free long
distance, calling and debit cards, international toll-free service, 24-hour
bilingual operator services, intra-island local service in Puerto Rico, private
lines, frame relay, international inbound service, international country to
country calling services and international callthrough from selected markets.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

 Principles of Consolidation

   The accompanying consolidated financial statements include the accounts of
TresCom and its wholly-owned subsidiaries. All significant intercompany
transactions and balances have been eliminated in consolidation.

 Cash and Cash Equivalents

   TresCom considers all highly liquid investments with original maturities of
three months or less to be cash equivalents. Cash equivalents are recorded at
cost, which approximates fair market value.

 Property and Equipment

   Property and equipment is recorded at cost. Depreciation and amortization is
provided for financial reporting purposes using the straight-line method over
the following estimated useful lives:

<TABLE>
       <S>                                                         <C>
       Transmission and communications equipment.................. 3 to 20 years
       Furniture, fixtures and other..............................  3 to 7 years
</TABLE>

   The costs of software and software upgrades purchased for internal use are
capitalized. Significant capital projects are constantly being initiated as
TresCom continues to expand its network. Beginning in 1996, a substantial
amount of employee time was required to properly plan, install, test and
certify the equipment associated with these projects. In connection with these
projects, TresCom capitalized $1,229 and $1,450 in direct and indirect employee
costs during 1997 and 1996, respectively.

 Change in Accounting Estimate

   During the first quarter of 1997, TresCom changed the estimated useful life
of fiber optic undersea cables from 10 to 20 years to conform to the
predominant industry standard. The change in depreciation expense associated
with the revised estimated useful life of fiber optic undersea cables was

                (In Thousands, Except Share and Per Share Data)

advertising costs, which are capitalized and amortized over the expected period
of future benefit. Direct-response advertising programs were implemented during
1996 and consist of fees paid to various telemarketing entities and internal
costs of performing telemarketing activities. The capitalized costs are
amortized over a nine month period beginning in the month revenues associated
with those costs are first generated.

   At December 31, 1997 and 1996, advertising costs totaling $770 and $1,390,
respectively, were recorded as other current assets. Advertising expense for
the years ended December 31, 1997, 1996 and 1995 were $4,865, $2,047 and
$1,359, respectively.

 Other Assets

   The excess of cost over net assets of businesses acquired represents the
excess of the consideration paid over the fair value of the net assets acquired
and is amortized on a straight-line basis over 35 years. Customer bases are
recorded based on the estimated value of the customer bases acquired in the
acquisition of businesses and are amortized on a straight-line basis over
periods ranging from three to seven years.

   Other assets are periodically reviewed by TresCom for impairments where the
fair value is less than the carrying value.

   Legal expenses and other direct costs incurred in connection with obtaining
financing agreements are deferred and amortized over the life of the financing
agreements. Such capitalized costs amounted to $482 and $86 during the years
ended December 31, 1997 and 1996, respectively. Accumulated amortization of
deferred financing costs was $133 and $10 at December 31, 1997 and 1996,
respectively.

 Use of Estimates

   The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.

 Revenues

   Revenues are derived primarily from the provision of long-distance
telecommunications services and are recognized when the services are provided.
In 1997, TresCom recognized $543 of revenue from the sale of excess
Indefeasible Rights of Use (IRU) on undersea digital fiber optic transmission
cables.

 Cost of Services

   Cost of services include payments to local exchange carriers (LECs),
interexchange carriers, post, telegraph and telephone organizations (PTTs) and
telecommunications administrations (TAs) primarily for access and transport
charges.

 Concentrations of Credit Risk and Major Customers

   TresCom derives a majority of its operating revenues from wholesale
customers as well as commercial customers in Florida, New York, St. Thomas and
Puerto Rico. Financial instruments which potentially subject TresCom to
concentrations of credit risk consist principally of accounts receivable.
TresCom's allowance for doubtful accounts is based upon management's estimates
and historical experience. In situations where TresCom deems appropriate,
prepayment and/or cash deposits or letters of credit are required for the
provision of services.

 Income Taxes

   TresCom accounts for income taxes under the liability method. Under the
liability method, deferred income taxes are recorded to reflect the net tax
effects of temporary differences between the carrying amounts of assets and
liabilities for financial reporting and the amounts used for income tax
purposes.

 New Accounting Pronouncements

   In 1996, TresCom adopted Statement of Financial Accounting Standards No.
121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived
Assets to be Disposed Of" (SFAS 121). The adoption of SFAS 121 did not have any
effect on the financial statements. In 1996, TresCom also adopted the
provisions of Statement of Financial Accounting Standards No. 123, "Accounting
for Stock-Based Compensation" (SFAS 123) (See Note 5).

   In 1997, the Financial Accounting Standards Board issued Statement No. 128,
"Earnings Per Share" (see Note 13). Statement No. 128 replaced the calculation
of primary and fully diluted earnings per share with basic and diluted earnings
per share. Unlike primary earnings per share, basic earnings per share excludes
any dilutive effects of options, warrants and convertible securities. Diluted
earnings per share is very similar to the previously reported fully diluted
earnings per share. All earnings per share amounts for all periods have been
presented, and where appropriate, restated to conform to the Statement No. 128
requirements.

   Comparative net loss per share data have been restated for prior periods. In
connection therewith, common stock, options and warrants issued within one year
prior to the original filing of TresCom's initial public offering (the IPO) at
prices below the IPO price, which had previously been considered outstanding
for all periods presented even though antidilutive, have been reflected in the
computations of basic and diluted net loss per share in accordance with
Statement of Financial Accounting Standards No. 128 and Securities and Exchange
Commission Staff Accounting Bulletin No. 98, issued February 3, 1998. Such
common stock has been treated as outstanding only since issuance, and options
and warrants have been excluded from the computations as they are considered
antidilutive.

   In June of 1997, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 130 (SFAS 130), "Reporting Comprehensive
Income" and Statement of Financial Accounting Standards No. 131 (SFAS 131),
"Disclosures about Segments of an Enterprise and Related Information" which are
both effective for fiscal years beginning after December 15, 1997. Management
believes that the adoption of SFAS 130 and SFAS 131 will not have a material
adverse effect on TresCom's consolidated financial statements.

 Reclassification

   Certain prior year amounts have been reclassified to conform with current
year presentation.

</TABLE>

   In November 1994, a wholly-owned subsidiary of TresCom obtained from a bank
a revolving credit facility (the Bank Facility) with an aggregate commitment of
$27,000, which expired on June 30, 1996. On February 16, 1996, TresCom repaid
all outstanding amounts borrowed under the Bank Facility. Extraordinary expense
of $432 was recognized to write-off the remaining deferred financing costs
associated with the Bank Facility.

   Under the terms of the Bank Facility, TresCom was required to maintain at
least 50% of its debt on a fixed rate basis and, as a result, entered into an
interest rate swap agreement and interest rate cap agreement (the Instruments)
with the lending bank to convert variable interest rate payments to fixed
payments. The estimated fair value (i.e., the net present value of the amount
TresCom was required to pay the counterpart over the remaining term of the
agreement) of the Instruments, based upon the quoted market price provided by
the financial institution was $562 at December 31, 1995. On September 18, 1996,
when the net settlement value was $302, the Instruments were paid off in full.

   In October and November 1995, TresCom borrowed $7,000 and $3,000,
respectively, under one-year notes bearing interest at 12% compounded quarterly
from a major shareholder of TresCom. In connection with these notes, TresCom
issued a warrant to purchase 358,034 shares of common stock at an exercise
price of $0.42 per share. The warrants are exercisable immediately and expire
on October 2, 2007. Of the $10,000 in borrowings, approximately $2,400 has been
allocated to the value of the warrants. On February 14, 1996, TresCom repaid
the entire balance relating to the notes. Accordingly, extraordinary interest
expense in the amount of $1,524 was recognized in the first quarter of 1996.

   During the third quarter of 1996, TresCom established a relationship with a
commercial bank to provide asset financing. TresCom utilized approximately
$4,310 in the fourth quarter of 1996 for capital projects. An additional $1,156
was utilized in the second quarter of 1997.

   During the fourth quarter of 1996, TresCom established a $5,000 line of
credit with a commercial bank (the Credit Facility) secured by certain accounts
receivable. The Credit Facility, as amended on March 27, 1997, contained
standard debt covenants relating to financial position and performance, as well
as restrictions on the declaration and payment of dividends. Through July 31,
1997, TresCom was either in compliance or received waivers with respect to all
covenants under the Credit Facility.

   On July 31, 1997, TresCom entered into a Revolving Credit and Security
Agreement (the Revolving Credit Agreement) secured by TresCom's accounts
receivable and certain intangible assets. The maximum borrowing under this
agreement is $25,000; however, the amount available to be borrowed is based
upon TresCom's pledged accounts receivable and intangible assets.

   On July 31, 1997, all borrowings under the Credit Facility were repaid in
full with borrowings under the Revolving Credit Agreement and the Credit
Facility was terminated. As of December 31, 1997, availability under the
Revolving Credit Agreement was approximately $19,702, of which $15,645
(including approximately $600 of letters of credit) had been utilized. At
December 31, 1997, TresCom was in compliance with all covenants under the
Revolving Credit Agreement.

   Principal payments on all debt obligations are:

4. LEASE OBLIGATIONS

   TresCom occupies office facilities and leases certain equipment and software
under noncancelable operating leases. Rental expense for the years ended
December 31, 1997, 1996 and 1995 was $1,703, $1,421 and $1,341, respectively.

   During the years ended December 31, 1997 and 1996, TresCom acquired
communication equipment of approximately $1,156 and $4,310, respectively, under
capital lease obligations. Asset balances for property acquired under capital

   Non-cash compensation expense was recorded over the vesting period of the
options. Accordingly, $257, $1,264 and $139 of non-cash compensation expense
was recorded in the years ended December 31, 1997, 1996 and 1995, respectively.

   TresCom follows the requirements of Accounting Principles Board Opinion No.
25, "Accounting for Stock Issued to Employees" to account for its stock option
plan and, accordingly, compensation cost is recognized in the consolidated
statements of operations for the stock option plan to the extent the options
are granted at prices below fair market value. TresCom adopted SFAS 123, which
requires certain disclosures about stock-based employee compensation
arrangements. SFAS 123 requires pro forma disclosure of the impact on net
income and earnings per share if the fair value method defined in SFAS 123 had
been used. The fair value for these options was estimated at the date of grant
using a minimum value option valuation method for options granted prior to the
IPO and a Black-Scholes option valuation model for options granted after the
IPO with the following weighted-average assumptions: a risk-free interest rate
of 6.1%; a dividend yield of 0%; a volatility factor of the expected market
price of the TresCom common stock of 1.207 for options granted during 1997 and
 .729 for options granted during 1996 and 1995, and an expected life of five
years.

   The Black-Scholes option valuation model was developed for use in estimating
the fair value of traded options which have no vesting restrictions and are
fully transferable. In addition, option valuation models require the input of
highly subjective assumptions including the expected stock price volatility.
Because TresCom's stock options have characteristics significantly different
from those of traded options, and because change in the subjective input
assumptions can materially affect the fair value estimate, in management's
opinion, the existing models do not necessarily provide a reliable single
measure of the fair value of its stock options.

   The weighted average grant date fair value of options granted in 1997, 1996
and 1995 is $6.46, $7.88 and $10.50 per share, respectively. The options
granted during 1995 had exercise prices below market value and the options
granted during 1997 and 1996 had exercise prices at or above fair market value.

   For purposes of pro-forma disclosures, the estimated fair value of the
options is amortized to expense over the vesting period of the options. The
SFAS 123 pro-forma information is as follows:

   The net change in TresCom's valuation allowance was $5,574, $(314) and
$3,056 for the years ended December 31, 1997, 1996 and 1995, respectively.

   On July 17, 1989, the Industrial Development Commission of the U.S. Virgin
Islands (U.S.V.I.) granted STSJ tax benefits to cover long-distance
telecommunications services in the U.S. Virgin Islands. These benefits include
a 90% exemption from income taxes for a ten-year period effective January 1,
1989.

</TABLE>

   At December 31, 1997, TresCom has U.S. and foreign net operating loss
carryforwards for tax purposes of $24,335 and $12,354, respectively. These net
operating loss carryforwards expire in the years 1997 through 2012.

7. RETIREMENT PLAN

   TresCom maintains the TresCom 401(k) Savings and Retirement Plan for all
U.S. and U.S.V.I. subsidiaries and the TresCom 165(e) Savings and Retirement
Plan for the Puerto Rican subsidiary. Employees age 21 or older are eligible to
participate six months after their date of hire and to elect to defer a
percentage of his/her salary. TresCom has the discretion to make contributions
to the TresCom 401(k) Savings and Retirement Plan and TresCom 165(e) Saving and
Retirement Plan. In 1996, 25,000 shares of stock in TresCom were authorized as
retirement plan contributions. In 1997 and 1996, 4,439 and 2,065 shares,
respectively, were allocated to the TresCom 401(k) Savings and Retirement Plan
and the TresCom 165(e) Savings and Retirement Plan for aggregate amounts of
approximately $31 and $16, respectively.

8. COMMITMENTS AND CONTINGENCIES

   TresCom is involved in various claims and is subject to possible actions
arising out of the normal course of its business. Although the ultimate outcome
of these claims cannot be ascertained at this time, it is the opinion of
TresCom's management, based on knowledge of the facts and advice of counsel,
that the resolution of such claims and actions will not have a material adverse
effect on TresCom's financial condition or results of operations.

   TresCom has commitments under various types of agreements for the purchase
of property and equipment to continue expansion of its network. Portions of
such agreements not completed at year end are not reflected in the consolidated
financial statements. These commitments were approximately $1,000 at year end
1997.

9. SETTLEMENTS

   In the past, TresCom incurred some significant charges as a result of
disputes with carriers. These charges amounted to $4,100 and $900 in the first
and second quarter of 1995, respectively. In addition, significant losses
resulting from settlements with customers totaled $4,069 during the first
quarter of 1995.

   The fair values of all other long-term obligations approximate the carrying
values and are therefore not disclosed.

11. RELATED PARTY TRANSACTIONS

   During 1996, an affiliate of a major shareholder of TresCom owned
approximately 20% of LCI International, Inc. (LCI). TresCom buys network
services from and provides network services to LCI. At December 31, 1996, the
net amount due to LCI was $1,935. During 1996, $7,140 of services were provided
and $5,453 were used. During 1997, the affiliate of TresCom's major shareholder
reduced their ownership stake to an insignificant percentage.

   In December 1996, TresCom acquired 100% of the common stock of Intex
Telecommunications, Inc. from LCI. The purchase price consideration was 394,095
shares of TresCom common stock.

12. NATURAL DISASTER

   On September 16, 1995, Hurricane Marilyn damaged the island of St. Thomas
where TresCom has significant operations. TresCom's Property and Business
Interruption Insurance covered a significant portion of the damages to
equipment and certain losses from operations. At September 30, 1995, TresCom
estimated its exposure relating to the hurricane to be $2,500. Based on visits
to the affected area, review of accounts receivable and actual settlements with
customers, management revised its estimate of losses resulting from the
hurricane to $1,717. Accordingly, the net loss for the quarter ended December
31, 1996 included this change in estimate of $783.

14. SUBSEQUENT EVENTS

   In February 1998, TresCom entered into a definitive Agreement and Plan of
Merger with Primus Telecommunications Group, Inc. (Primus) and Taurus
Acquisition Corporation, a wholly-owned subsidiary of Primus (Taurus). Pursuant
to the terms of the Agreement and Plan of Merger, as amended, it is
contemplated that Taurus will merge with and into TresCom, that TresCom will be
the surviving corporation and that Primus will acquire 100% of the issued and
outstanding shares of TresCom common stock. The transaction is expected to be
completed during the second quarter of 1998 and is subject to, among other
things, the approval of both Primus's and TresCom's shareholders and certain
regulatory authorities.

                       INDEPENDENT AUDITORS' REPORT

The Board of Directors
Telegroup, Inc.:

   We have audited the accompanying combined balance sheets of Telegroup, Inc.
and certain subsidiaries (the Company) as of December 31, 1997 and 1998 and the
related combined statements of operations, comprehensive losses, shareholders'
equity (deficit), and cash flows for each of the years in the three-year period
ended December 31, 1998. These combined financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these combined financial statements based on our audits.

   We conducted our audits in accordance with generally accepted auditing
standards. 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 audits provide a reasonable basis
for our opinion.

   In our opinion, the combined financial statements referred to above present
fairly, in all material respects, the financial position of Telegroup, Inc. and
certain subsidiaries as of December 31, 1997 and 1998 and the results of its
operations and its cash flows for each of the years in the three-year period
ended December 31, 1998, in conformity with generally accepted accounting
principles.

   The accompanying combined financial statements have been prepared assuming
that the Company will continue as a going concern. As discussed in note 1 to
the combined financial statements, the Company has filed for protection under
Chapter 11 of the United States Bankruptcy Code due to significant financial
and liquidity problems. These circumstances raise substantial doubt about its
ability to continue as a going concern. Management's plans in regard to these
matters are also described in note 1. The financial statements do not include
any adjustments that might result from the outcome of this uncertainty.

                 TELEGROUP, INC. AND CERTAIN SUBSIDIARIES

                  NOTES TO COMBINED FINANCIAL STATEMENTS

                     December 31, 1996, 1997 and 1998

(1) BASIS OF PRESENTATION

   On February 10, 1999 (the Filing Date), amidst increasing financial and
liquidity problems, Telegroup, Inc. filed for protection under Chapter 11 of
the United States (U.S.) Bankruptcy Code, as amended (the Bankruptcy Code).
Telegroup, Inc. filed a voluntary petition to operate as a Debtor in Possession
(DIP) in the U.S. Bankruptcy Court District of New Jersey (the Bankruptcy
Court). Telegroup, Inc.'s subsidiary companies have not filed for Chapter 11
protection. Telegroup, Inc.'s equity interests in such subsidiaries represent
assets of the bankruptcy estate.

   The commencement of a Chapter 11 bankruptcy proceeding results in the
imposition of an automatic stay against the commencement or continuation of any
judicial, administrative or other proceeding against Telegroup, Inc., against
any act to obtain possession of property of or from Telegroup, Inc., and
against any act to create, perfect or enforce any lien against property of
Telegroup, Inc., subject to certain exceptions permitted under the Bankruptcy
Code. Telegroup, Inc.'s creditors, therefore, are generally prohibited from
attempting to collect prepetition debts without the consent of the Bankruptcy
Court. Any creditor may seek relief from the automatic stay and, if applicable,
enforce a lien against its collateral, if authorized by the Bankruptcy Court.
There are various other provisions of the Bankruptcy Code which may impose
limitations or constraints on Telegroup, Inc.'s operations.

   Pursuant to provisions of the Bankruptcy Code, claims arising prior to the
filing of the petition under Chapter 11 of the Bankruptcy Code may not be paid
outside of a plan of reorganization without prior approval of the Bankruptcy
Court. Certain prepetition claims have subsequently been paid or satisfied with
approval from the Bankruptcy Court. These claims include payments for
commissions and wages, salaries and employee benefits.

   Since the Filing Date, Telegroup, Inc. has continued in possession of its
properties and as a DIP is authorized to operate and manage its business and to
enter into all transactions that it could have entered into in the ordinary
course of its business had there been no Chapter 11 filing. Subsequent to the
Filing Date, Telegroup, Inc. restructured the terms of many of its
relationships with critical telecommunications service carriers and reduced
significant portions of its general and administrative costs, in an effort to
effectively manage its liquidity problems. In March 1999, the Bankruptcy Court
set a date of June 15, 1999 (the Bar Date) as the date for which all pre-Filing
Date claims could be filed by creditors against Telegroup, Inc.

   During the first quarter of 1999, Telegroup, Inc. continued to operate as a
DIP and petitioned the Bankruptcy Court for approval to sell the majority of
its assets under Sections 363 and 365 of the Bankruptcy Code. Following the
approval of the Bankruptcy Court and a public notice, on May 26, 1999, Primus
Telecommunications, Inc. (Primus) emerged as highest bidder at the auction and
committed to purchase the majority of Telegroup, Inc.'s assets, including the
common stock of Telegroup, Inc.'s subsidiary companies, excluding the
subsidiaries located in Australia and New Zealand, which include Telegroup
Network Services Australia Pty Limited, Telegroup Network Services New Zealand
Pty Limited, and Switch Telecommunications Pty Limited (collectively the
Australian and New Zealand Subsidiaries) (the Core Business Assets), for
$71,825,000. The sale of the Core Business Assets to Primus, including an
additional sale of accounts receivable and other assets less assumed
liabilities for approximately $22,190,000, closed on June 30, 1999. The
effective date of these transactions was June 1, 1999. The purchase price was
paid by Primus in unregistered debt securities of $45,467,000 in the form of
11.25% Senior Notes due 2009 (the Primus Notes), a $4,592,006 promissory note
due 60% on July 30, 1999 and 40% on August 31, 1999, and cash.

   In addition, the auction resulted in other telecommunications carriers
purchasing certain other fixed assets of Telegroup, Inc. for approximately
$5,600,000 in cash.

                 TELEGROUP, INC. AND CERTAIN SUBSIDIARIES

            NOTES TO COMBINED FINANCIAL STATEMENTS--(Continued)

                     December 31, 1996, 1997 and 1998

   Telegroup, Inc. used the auction proceeds to pay in full its asset-based
line of credit and term loan with Foothill Capital Corp. (Foothill) (see note
3). The remaining assets of Telegroup, Inc., consisting primarily of cash and
Primus Notes obtained from the sale of assets from the auction, are being held
subject to the review and reconciliation of creditors' proofs of claims that
have been filed with the Bankruptcy Court against Telegroup, Inc. as of the Bar
Date. Management of Telegroup, Inc. have estimated and accrued known claims it
believes are valid relating to products and/or services received prior to
December 31, 1998 in the accompanying combined financial statements. However, a
number of disputed claims exist which are individually significant in amount
and which, together, are materially in excess of the amounts reflected in the
accompanying combined financial statements. Disputed claims for products and/or
services received prior to December 31, 1998 have been reflected at such
amounts, if any, that are estimated will be allowed. Disputed claims could be
greater than or less than the amounts reflected in the accompanying financial
statements and these differences may be material. It is anticipated that claims
will be reconciled in connection with the consummation of a Chapter 11 plan of
liquidation. The ultimate amount and classification of claims which will be
allowed can not be estimated at this time.

   Pursuant to provisions of the Bankruptcy Code, Telegroup, Inc. has until the
confirmation of a plan of reorganization to assume or reject executory
contracts and unexpired leases of personal property, subject to the discretion
of the Bankruptcy Court, on request of a party to such contract or lease, to
require Telegroup, Inc. to determine within a specified time period whether to
assume a particular executory contract or unexpired lease of personal property.
Generally, a Chapter 11 debtor must assume all leases of nonresidential real
property within 60 days of its Chapter 11 filing, or such leases will be deemed
rejected, unless the Bankruptcy Court, for cause, within such 60-day period
establishes a longer period for assumption decisions. Subject to certain
exceptions, by order of the Bankruptcy Court, Telegroup, Inc. obtained an
extension of time within which to assume or reject its nonresidential real
property leases.

   Assumption of an executory contract or unexpired lease under the Bankruptcy
Code requires Telegroup, Inc., among other things, to cure all defaults under
such executory contract or unexpired lease. Rejection of an executory contract
or unexpired lease constitutes a breach of such executory contract or unexpired
lease immediately before the date of the filing of the Chapter 11 petition,
giving the other party to the contract or unexpired lease the right to assert a
general unsecured claim against the bankruptcy estate for damages arising out
of the breach. Prior to the filing of Telegroup, Inc.'s plan of liquidation,
Telegroup, Inc. anticipates that it will notify the Bankruptcy Court of those
contracts and leases that it will assume or reject as of the effective date of
the plan of liquidation. Included in Primus's purchase agreement, Primus will
assume certain executory contracts and unexpired leases. Telegroup, Inc. will
reject all remaining contracts and leases. Primus continues to review
Telegroup, Inc.'s contracts and leases to determine which ones they will
assume. The Disclosure Statement, which will be filed concurrently with the
plan of liquidation, will set forth Telegroup, Inc.'s estimates of the
aggregate cure amounts and rejection damage claims to be incurred in connection
with assumptions and rejections for only those contracts and leases not already
rejected or assumed prior to the filing of the plan of liquidation. Rejection
of these executory contracts and unexpired leases could result in additional
claims against the estate.

   The accompanying combined financial statements have been prepared in order
for Primus to comply with certain reporting requirements of the Securities and
Exchange Commission. The accompanying combined financial statements represent
the accounts of Telegroup, Inc. and certain subsidiaries (the Company). As
Primus is not purchasing the Australian and New Zealand Subsidiaries, these
subsidiaries, in which Telegroup, Inc. has significant control, are excluded
from the combined financial statements. In accordance with the accounting rules
prescribed for "carve-out" financial statements, the excess of the purchase
price of the Australian and New Zealand Subsidiaries over fair value of their
net assets acquired recorded by Telegroup, Inc., the financial position,
results of operations, comprehensive losses and cash flows for these

subsidiaries are not included in the combined financial statements. The net
effect of the "carve-out" adjustment is reflected in retained deficit in the
combined financial statements.

   The accompanying combined financial statements have been prepared on a going
concern basis which assumes continuity of operations and realization of assets
and liquidation of liabilities in the ordinary course of business. As discussed
herein, there are significant uncertainties relating to the ability of the
Company to continue as a going concern. The combined financial statements do
not include any adjustments relating to the recoverability and classification
of recorded asset amounts, or the amounts and classification of liabilities
that might be necessary as a result of the outcome of the uncertainties
discussed herein.

   All significant intercompany accounts and transactions have been eliminated
in consolidation.

(2) NATURE OF BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES

 Nature of Business

   The Company is an alternative provider of domestic and international
telecommunications services. The Company's revenues are derived from the sale
of telecommunications to retail customers, typically residential users and
small- to medium-sized business and wholesale customers, typically
telecommunications carriers. The Company's customers are principally located in
the United States, Europe and the Pacific Rim. In both the retail and wholesale
aspects of its business, the Company extends credit to customers on an
unsecured basis with the risk of loss limited to outstanding amounts.

   The Company markets its services through a worldwide network of independent
agents and supervisory "country coordinators". The Company extends credit to
its sales representatives and country coordinators on an unsecured basis with
the risk of loss limited to outstanding amounts, less commissions payable to
the representatives and coordinators.

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

 Cash Equivalents and Securities Available-for-sale

   The Company considers all highly liquid investments with original maturities
of three months or less to be cash equivalents. At December 31, 1997, cash
equivalents consisted of money market instruments, U.S. Government securities,
and commercial paper totaling $70,133,492. There were no cash equivalents at
December 31, 1998. Securities available-for-sale represent U.S. Government
securities with maturities greater than three months. Securities available-for-
sale are recorded at the lower of amortized cost or market value. At December
31, 1997, amortized cost approximated market value.

 Property and Equipment

   Property and equipment are stated at cost. Equipment held under capital
leases are stated at the lower of the fair value of the asset or the net
present value of the minimum lease payments at the inception of the lease.
Depreciation on property and equipment is provided using the straight-line
method over the estimated useful lives of the assets. Equipment held under
capital leases and leasehold improvements are amortized straight-line over the
shorter of the lease term or estimated useful life of the asset. Amortization
of assets held under capital leases and leasehold improvements are included
with depreciation expense.

                     December 31, 1996, 1997 and 1998

 Capitalized Software Development Costs

   The Company capitalizes software costs incurred in the development of its
telecommunications switching software, billing systems and other support
platforms. The Company capitalizes external direct costs of materials and
services consumed, internal direct payroll and payroll related costs incurred
and estimated costs of debt funds used in the development of internal use
software. Capitalization begins upon the completion of the preliminary project
stage and ends when the software is substantially complete and ready for its
intended use. Amortization of capitalized software is provided using the
straight-line method over the software's estimated useful life, which ranges
from one to five years. For the years ended December 31, 1997 and 1998,
amortization of software development costs totaled $498,682 and $447,221,
respectively. There was no amortization during 1996 as the software had not yet
been complete and ready for its intended use.

 Stock Option Plan

   The Company accounts for its stock option plan using the intrinsic value
based method prescribed by Accounting Principles Board Opinion No. 25,
Accounting for Stock Issued to Employees (APB No. 25), and related
interpretations. As such, compensation expense is recorded on the date of grant
only if the current market price of the underlying stock exceeds the exercise
price. On January 1, 1996, the Company adopted Statement of Financial
Accounting Standards (SFAS) No. 123, Accounting for Stock-Based Compensation
(SFAS No. 123), which permits entities to recognize as expense over the vesting
period the fair value of all stock-based awards on the date of grant.
Alternatively, SFAS No. 123 also allows entities to continue to apply the
provisions of APB No. 25 and provide pro forma net income disclosures as if the
fair-value method defined in SFAS No. 123 had been applied. The Company has
elected to continue to apply the provisions of APB No. 25 and provide the pro
forma disclosure provisions of SFAS No. 123.

 Impairment of Long-lived Assets

   The Company accounts for long-lived assets in accordance with the provisions
of SFAS No. 121, Accounting for the Impairment of Long-Lived Assets and for
Long-Lived Assets to be Disposed of. This statement requires that long-lived
assets and certain identifiable intangibles be reviewed for impairment whenever
events or changes in circumstances indicate that the carrying value of an asset
may not be recoverable. Recoverability of assets to be held and used is
measured by a comparison of the carrying amount of an asset to future cash
flows expected to be generated by the asset. If such assets are considered to
be impaired, the impairment to be recognized is measured by the amount by which
the carrying amount of the assets exceed the fair value of the assets. Fair
value is determined using valuation techniques such as quoted market prices or
the discounted present value of expected future cash flows. Assets to be
disposed of are reported at the lower of the carrying amount or fair value less
costs to sell.

 Goodwill

   Goodwill results from the application of the purchase method of accounting
for business combinations and represents the excess of purchase price over fair
value of net assets acquired. Amortization is provided using the straight-line
method over a maximum of fifteen years. For business combinations relating to
the purchase of an entity's customers, goodwill is amortized using an
accelerated method over the estimated life of the customers purchased or three
years, whichever is shorter. Impairment is determined pursuant to the
methodology used for other long-lived assets.

                     December 31, 1996, 1997 and 1998

 Income Taxes

   The Company accounts for income taxes under the provisions of SFAS No. 109,
Accounting for Income Taxes (SFAS No. 109). Under the asset and liability
method of SFAS No. 109, deferred tax assets and liabilities are recognized for
the future tax consequences attributable to differences between the financial
statement carrying amounts of existing assets and liabilities and their
respective tax bases. Deferred tax assets and liabilities are measured using
enacted tax rates expected to apply to taxable income in the years in which
those temporary differences are expected to be recovered or settled. Under SFAS
No. 109, the effect on deferred tax assets and liabilities of a change in tax
rates is recognized in income in the period that includes the enactment date.

 Estimates

   The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities at the
date of the financial statements and the reported amounts of revenue and
expenses during the reporting period. Actual amounts could differ from those
estimates.

 Business and Credit Concentration

   Financial instruments which potentially expose the Company to a
concentration of credit risk, as defined by SFAS No. 105, Disclosure of
Information about Financial Instruments with Off-Balance-Sheet Risk and
Financial Instruments with Concentrations of Credit Risk (SFAS No. 105),
consist primarily of accounts receivable. At December 31, 1998, the Company's
accounts receivable balance from customers in countries outside of the U.S. was
approximately $31,400,000 with an associated reserve for credit losses of
approximately $2,400,000. The Company estimates an allowance for doubtful
accounts based on the credit worthiness of its customers as well as general
economic conditions. Consequently, an adverse change in those factors could
effect the Company's estimate of its bad debts.

 Foreign Currency Contracts

   The Company uses foreign currency contracts to hedge foreign currency risk
associated with its international accounts receivable balances. Gains or losses
pursuant to these foreign currency contracts are reflected as an adjustment of
the carrying value of the hedged accounts receivable. At December 31, 1997 and
1998, the Company had no material deferred hedging gains or losses.

 Revenues, Cost of Revenues and Commissions Expense

   Revenues from retail telecommunications services are recognized when
customer calls are completed. Revenues from wholesale telecommunications
services are recognized when the wholesale carrier's customers' calls are
completed. Cost of retail and wholesale revenues are based primarily on the
direct costs associated with owned and leased transmission capacity and the
cost of transmitting and terminating traffic on other carriers' facilities. The
Company does not differentiate between the cost of providing transmission
services on a retail or wholesale basis. Commissions paid to acquire customer
call traffic are expensed in the period when associated call revenues are
recognized.

 Prepaid Phone Cards

   Substantially all the prepaid phone cards sold by the Company have an
expiration date of twenty-four months after issuance or six months after last
use. The Company records the net sales price as deferred revenue

when cards are sold and recognizes revenue as the ultimate consumer utilizes
calling time. Deferred revenue relating to unused calling time remaining at
each card's expiration is recognized as revenue upon the expiration of such
card.

 Comprehensive Income

   On January 1, 1998, the Company adopted SFAS No. 130, Reporting
Comprehensive Income (SFAS No. 130). SFAS No. 130 establishes standards for
reporting and presentation of comprehensive income and its components in a full
set of financial statements. Comprehensive income consists of the Company's net
losses and foreign currency translation adjustments and is presented in the
combined statements of comprehensive losses. SFAS No. 130 requires only
additional disclosures in the combined financial statements; it does not affect
the Company's financial position or results of operations.

 Foreign Currency Translation

   The functional currency of the Company is the U.S. dollar. The functional
currency of the Company's foreign operations generally is the applicable local
currency for the foreign subsidiary. Assets and liabilities of its foreign
subsidiaries are translated at the spot rate in effect at the applicable
reporting date, and the combined statements of operations and the Company's
share of the results of operations of its foreign subsidiaries are translated
at the average exchange rates in effect during the applicable period. The
resulting unrealized cumulative translation adjustment is recorded as a
separate component of equity and is included in other comprehensive income
(deficit).

 Fair Value of Financial Instruments

   The fair values of cash and cash equivalents and receivables are estimated
to approximate carrying value due to the short-term maturities of these
financial instruments. The carrying value of accounts payable, commissions
payable, lease obligations, notes payable and long-term debt cannot be
reasonably estimated at December 31, 1998 due to the Company's financial and
liquidity problems and uncertainties surrounding the Bankruptcy proceedings
(see note 1).

 Valuation of Common Stock Issuances

   The Company issues shares of common stock for consideration on certain
transactions. The Company values the shares issued based on the fair-market
value of the securities issued.

 Segment Reporting

   On January 1, 1998, the Company adopted SFAS No. 131, Disclosures about
Segments of an Enterprise and Related Information (SFAS No. 131). SFAS No. 131
establishes standards for the way that public business enterprises report
information about operating segments. The basis for determining an enterprise's
operating segments is the manner in which management operates the business.

 New Accounting Pronouncements

   SFAS No. 133, Accounting for Derivative Instruments and Hedging Activities,
was issued in June 1998. This statement provides new accounting and reporting
standards for the use of derivative instruments. Adoption of this statement is
required by the Company effective January 1, 2001. Management believes that the
impact of such adoption will not be material to the financial statements.

 Senior Subordinated Notes

   On November 27, 1996, the Company completed a private placement (Private
Offering) of 12% senior subordinated notes (the Subordinated Notes) for gross
proceeds of $20,000,000 which was due and payable on November 27, 2003. Net
proceeds from the Private Offering, after issuance costs of $1,450,281, were
$18,549,719. In connection with the Private Offering, the Company issued 20,000
warrants to purchase 1,160,107 shares of the Company's common stock (see note
8).

   The Subordinated Notes were originally recorded at $10,846,049 (a yield of
26.8%), which represents the $20,000,000 in proceeds less the $9,153,951 value
assigned to the detachable warrants, which is included in additional paid-in
capital. The value assigned to the warrants was being accreted to the debt
using the interest method over seven years. The accretion of the value assigned
to the warrants is included in interest expense in the accompanying combined
financial statements.

   On September 5, 1997, the Company prepaid in full all of the outstanding
Subordinated Notes. The Company paid $21,400,000, which included $20,000,000 in
principal and $1,400,000 for a prepayment penalty. In addition, the Company
recognized a loss of $8,741,419 and $1,298,882 for the write-off of the
unamortized original issue discount and debt issuance costs, respectively. The
early extinguishment of the Subordinated Notes is reflected on the combined
statement of operations as an extraordinary item, net of income taxes.

 Convertible Subordinated Notes

   On September 30, 1997, the Company issued $25,000,000 in aggregate principal
amount of convertible subordinated notes due April 15, 2005. Net proceeds from
the convertible notes, after issuance costs of $890,475, were $24,109,525.

   The convertible notes bear interest at 8% per annum, payable on each April
15 and October 15. The convertible notes are convertible into shares of common
stock of the Company at any time before April 15, 2005, at a conversion price
of $12.00 per share, subject to adjustment upon the occurrence of certain
events.

   The convertible notes are redeemable, in whole or in part, at the option of
the Company, at any time on or after October 15, 2000 at redemption prices
(expressed as a percentage of the principal amount) declining annually from
104% beginning October 15, 2000 to 100% beginning October 15, 2003 and
thereafter, together with accrued interest to the redemption date and subject
to certain conditions.

   The convertible notes are unsecured obligations of the Company and are
subordinated to all existing and future senior indebtedness of the Company.

 Senior Discount Notes

   On October 23, 1997, the Company issued $97,000,000 in aggregate principal
amount of 10.5% senior discount notes due November 1, 2004. Net proceeds from
the senior discount notes, after issuance costs of $2,863,083, were
$72,069,417. The discount of $22,067,500 recorded on the senior discount notes
is being accreted to the debt through May 1, 2000 using the interest method,
resulting in an effective interest rate of 10.5%. The accreted value of the
notes will equal the following on their semi-annual accrual dates.

</TABLE>

   Interest on the senior discount notes will neither accrue nor be payable
prior to May 1, 2000 and are payable on each May 1 and November 1 thereafter.
The notes are redeemable, in whole or in part, at the option of the Company, at
any time on or after November 1, 2001 at redemption prices (expressed as a
percentage of the principal amount) declining annually from 105.25% beginning
November 1, 2001 to 100% beginning November 1, 2004 and thereafter, together
with accrued interest to the redemption date and subject to certain conditions.

   The senior discount notes are unsecured obligations of the Company and are
subordinated to all existing and future indebtedness of the Company, with the
exception of the convertible subordinated notes.

   The convertible subordinated note and senior discount note indentures place
certain restrictions on the ability of the Company and its subsidiaries to (i)
incur additional indebtedness, (ii) make restricted payments (dividends,
redemptions and certain other payments), (iii) incur liens, (iv) enter into
mergers, consolidations or acquisitions, (v) sell or otherwise dispose of
property, business or assets, (vi) issue and sell preferred stock of a
subsidiary, and (vii) engage in transactions with affiliates.

   Subsequent to December 31, 1998, the Company defaulted on the convertible
subordinated note and senior discount note indentures by filing for protection
under Chapter 11 of the U.S. Bankruptcy Code (see note 1). As a result, these
notes are due and payable upon the request of the note holders. At December 31,
1998, these notes are presented as current liabilities in the combined
financial statements.

 Line of Credit

   At December 31, 1998, the Company had a $15,000,000 asset-based line of
credit and a $10,000,000 term loan with Foothill which provided for up to
$25,000,000 in committed credit. Aggregate borrowings under the line of credit
and term loan were $24,832,437 at December 31, 1998. Interest was payable at
Norwest Bank's most recently announced base rate (Reference Rate) plus 2%
(9.75% at December 31, 1998) and 12% per annum, respectively. Subsequent to
December 31, 1998, these rates increased due to an event of default. The
default rates were the Reference Rate plus 6% and 16% per annum, respectively.
The credit line and term loan were collateralized by the Company's accounts
receivable and substantially all other Company assets. The line of credit and
term loan were paid by the Company with the proceeds received from the sale of
the Company's assets on June 30, 1999 (see note 1).

(4) Business Combinations

   During 1996, 1997 and 1998, the Company acquired assets and/or common stock
of various companies providing products or services in the telecommunications
industry. Each acquisition was accounted for using the purchase method of
accounting and, accordingly, the net assets and results of operations are
included in the combined financial statements from the date of acquisition.

   On August 21, 1996, the Company purchased TeleContinent, S.A. for $200,000.
Also on August 21, 1996, the Company purchased Telegroup South Europe, Inc.
Consideration for the purchase was $1,031,547 and 262,116 shares of common
stock of the Company valued at $573,984, for total consideration of $1,605,531.
The value of the common stock was determined by management based on information
obtained from the Company's independent financial advisors. The aggregate
purchase price of the acquisitions was allocated based on estimated fair values
as follows:

</TABLE>

   During the fourth quarter of 1998, the Company recognized an impairment loss
of $1,221,729 for unamortized goodwill and other long-term intangible assets
relating to these subsidiaries.

   Pro forma operating results of the Company, assuming the 1996 acquisitions
were consummated on January 1, 1996, do not significantly differ from reported
amounts.

   On August 14, 1997, the Company acquired 60% of the common stock of, and
controlling interest in, PCS Telecom, Inc. (PCS). Consideration for the
purchase was $1,340,000 and 40,000 shares of unregistered common stock of the
Company valued at $470,000, for total consideration of $1,810,000. PCS is a
developer

companies. The aggregate purchase price of the acquisition was allocated based
on estimated fair values as follows:

</TABLE>

   The minority interest deficit of 40% was included in the calculation of the
Company's goodwill due to the Company recognizing 100% of PCS's net earnings
or losses until the historical shareholder's equity of PCS becomes positive.
No minority interest relating to PCS is reflected in the accompanying
financial statements, as PCS's net assets remained at a deficit since it's
acquisition.

   During the third quarter of 1998, the Company decided to significantly
scale back the development and assembly of calling card platforms at PCS. This
decision significantly reduced the Company's estimated future cash flows for
this subsidiary. As a result of the Company's estimated shortfalls of cash
flows, the Company recognized an impairment loss of $1,888,064 for unamortized
goodwill relating to this subsidiary. During the fourth quarter of 1998, the
Company abandoned the remaining operations of PCS. This resulted in an
impairment loss on the remaining long-lived assets of $552,996.

   Pro forma operating results of the Company, assuming the PCS acquisition
was consummated on January 1, 1996, do not significantly differ from reported
amounts.

   On January 15, 1998, the Company acquired the operations of its Australian
country coordinator. Consideration for the Australian country coordinator was
$107,584 and 107,036 shares of unregistered common stock of the Company valued
at $1,422,382, for total consideration of $1,529,966.

   The agreement also contained provisions which called for additional
consideration if certain financial measures of the acquired operations were
met subsequent to the date of acquisition. On June 5, 1998, the Company issued
an additional 39,600 shares of unregistered common stock valued at $426,639 to
the Australian coordinator to cancel such contingent consideration provisions
in the original purchase agreement.

   The aggregate purchase price of the acquisition was allocated based on
estimated fair values as follows:

<TABLE>
   <S>                                                                <C>

   Also on January 15, 1998, the Company acquired the operations of its New
Zealand country coordinator. Consideration for the New Zealand country
coordinator was $105,649 and 160,554 shares of unregistered common stock of
the Company valued at $2,135,368, for total consideration of $2,241,017.

   On April 23, 1998, the Company entered into a 25-year indefeasible right of
use (IRU) agreement with Cable and Wireless Communications Services Limited
(Cable and Wireless) for the right to use network


capacity in an under-sea fiber cable system. The Company paid $975,000 upon
execution of the agreement and $8,775,000 on June 15, 1998, the date of
activation. The cost of the IRU will be amortized over the life of the 25 year
agreement. In addition, the Company will be responsible for its pro rata share
of the cost and fees in relation to the operation and maintenance of the cable
system.

   On May 21, 1998, the Company entered into an IRU agreement with Southern
Cross Cable Network (Southern Cross) for the right to use network capacity in
an under-sea fiber cable system. The Company paid $2,520,000 upon execution of
the agreement. The IRU is scheduled to be ready for service by December 1999.
Provided that the cable system is ready for service by this date, the Company
will owe an additional $17,480,000, payable $2,480,000 in December 1999, and in
three annual installments of $5,000,000 thereafter. Until such time as the
cable system is ready for service, the Company is accounting for the initial
payment of $2,520,000 as a deposit. In addition, the Company will be
responsible for its pro rata share of the cost and fees in relation to the
operation and maintenance of the cable system. As a result of the Company's
financial and liquidity problems (see note 1), the Company does not intend to
make the scheduled payments on the Southern Cross IRU. The Company is
attempting to sell its interests in this IRU. The Company recorded an
impairment loss of $2,020,000 in 1998 on the Southern Cross deposit.

   In October 1998, the Company developed a restructuring plan (see note 10).
As part of this restructuring plan, management of the Company committed to a
plan to stop providing wholesale services to customers. Certain network
equipment assets and leasehold improvements were identified by the Company that
supported the wholesale business exclusively. These assets are reported on the
combined financial statements at the lower of net carrying value or estimated
fair value less costs to sell. The net carrying value of these assets at
December 31, 1998 is $1,254,354 and is included in network equipment. Upon
recording these assets at the lower of net carrying value or estimated fair
value, the Company recognized a loss of $1,263,991. This loss is

included in selling, general, and administrative expenses on the combined
financial statements. No further depreciation is being recorded on these
assets. The majority of these assets were sold in June 1999. All remaining
assets are expected to be sold by December 1999.

   As a result of the Company's financial and liquidity problems (see note 1),
management of the Company decided not to complete their Saville Systems
Convergent Billing Platform. Capitalized costs of $6,414,878 relating to this
billing system were recognized by the Company as an impairment loss in the
fourth quarter of 1998.

   Also in the fourth quarter of 1998, the Company recognized an impairment
loss of $740,775 relating to certain network equipment assets. Management
concluded that the future cash flows expected from these assets were less than
their net carrying value.

   The pro forma impact on income assumes no options will be forfeited. The pro
forma effects are not representative of the effects on reported net income for
future years, as most of the Company's employee stock option grants vest in
increments over a period of three years.

   Under SFAS No. 123, the per-share minimum value of stock options granted in
1996 was $0.61. For the year ended December 31, 1996, the minimum value,
estimated as of the grant date, does not take into account the expected
volatility of the underlying stock as prescribed by SFAS No. 123 for privately
held companies. The input variables used to calculate the per-share minimum
value included a weighted-average risk-free interest rate of 6.43%, no expected
dividend yields, and an estimated option life of 3 years.

   The per-share weighted-average fair value of stock options granted during
1997 and 1998 was $4.79 and $9.57, respectively. For the year ended December
31, 1997 and 1998, the fair value was estimated as of the grant date using the
Black-Scholes option pricing model. Input variables used in the model for 1997
and 1998 included a weighted-average risk-free interest rate of 5.33% and
4.70%, respectively, no expected dividend yields, an expected volatility factor
of 65% and 120%, respectively and an estimated option life of 3.05 and 3.00
years, respectively.

   Options granted during 1996 included performance based options. The
compensation expense recorded for these performance based options under APB No.
25 was greater than the expense recorded if the Company had determined
compensation cost under SFAS No. 123.

 Independent Agent Stock Option Plan

   During 1998, the Company adopted an incentive program for independent agents
that allows these non-employees to obtain stock options for certain
contributions made to the Company. Total options granted to agents were
321,400. The Company recognized commission expense of $474,241 as a result of
granting these options. The weighted-average grant-date fair value of these
options was approximately $1.48.

 Warrants--Private Offering

   In connection with the Private Offering, the Company issued warrants to
purchase 1,160,107 shares of the Company's common stock which, at the time of
closing of the Private Offering, represented 4% of the Company's fully diluted
common stock. On July 2, 1997, in accordance with the provisions of the Private
Offering Agreement, the warrants increased in value by 167,393 shares to
represent 4.5% of the Company's fully diluted common stock. During 1998, these
warrants were exercised in a cashless transaction. Total warrants exercised
were 1,327,333, which represented the total warrants outstanding of 1,327,500
less 167 warrants which were canceled. The canceled warrants represent the
value of the consideration (exercise price) due from the warrant holder at the
time of exercise.

 Warrants -- Forbearance Agreements

   During November and December 1998, the Company entered into forbearance
agreements with certain telecommunications carriers and vendors. The
forbearance agreements include terms of repayment to satisfy a portion of the
amount the Company owed the carrier or vendor at a date agreed to in the
agreement. At December 31, 1998, the Company owed $31,324,381 to carriers and
vendors under the terms of these agreements. The amounts owed by the Company
subject to the forbearance agreements is included in accounts payable in the
combined financial statements. The Company is to pay the carrier or vendor the
amount included in the forbearance agreement in equal installments over a three
to six month period. Interest on the forbearance agreements range from 7.75% to
12.00%. At December 31, 1998, accrued interest of $381,505 relating to these
agreements is included in accrued expenses on the combined financial
statements. Certain forbearance agreements provide for the Company to issue
warrants to the carrier or vendor upon the last monthly payment made under the
agreement. The number of warrants to be issued by the Company is equal to a
certain percent, ranging from 2% to 5% of the amount included in the
forbearance agreement. The total number of warrants to be issued by the Company
under these forbearance agreements at December 31, 1998 is 924,567. The
warrants are exercisable at any time after issuance and have an exercise price
of $1.00. Each warrant can be exercised for one common share of the Company's
common stock. The weighted-average grant-date fair value of these warrants was
$1.30.

   The Company entered into forbearance agreements with other
telecommunications carriers subsequent to December 31, 1998 totaling $579,482.
The total number of warrants to be issued under these forbearance agreements is
5,500, which can be exercised for one common share of the Company's common
stock.

 Warrants -- Building Purchase

   During December 1998, the Company issued 11,010 warrants for partial payment
on a building purchase. These warrants are exercisable through December 2001 at
an exercise price of $1.00. The weighted-average grant-date fair value of these
warrants was approximately $0.89. Each warrant can be exercised for one common
share of the Company's common stock.

   The valuation allowance for deferred tax assets as of December 31, 1997 and
1998 was $6,116,045 and $27,470,736, respectively. The net change in the total
valuation allowance for the years ended December 31, 1997 and 1998 was an
increase of $6,116,045 and $21,354,691, respectively. In assessing the
realizability of deferred tax assets, management considers whether it is more
likely than not that some portion or all of the deferred tax assets will not be
realized. The ultimate realization of deferred tax assets is dependent upon the
generation of future taxable income during the periods in which those temporary
differences become deductible. Management considers the scheduled reversal of
deferred tax liabilities, projected future taxable income, and tax planning
strategies in making this assessment. In order to fully realize the deferred
tax asset,

                 TELEGROUP, INC. AND CERTAIN SUBSIDIARIES

            NOTES TO COMBINED FINANCIAL STATEMENTS--(Continued)

                     December 31, 1996, 1997 and 1998

the Company will need to generate future taxable income of approximately
$80,000,000 prior to the expiration of the net operating loss carryforwards in
2018. Taxable loss for the years ended December 31, 1997 and 1998 was
approximately $22,000,000 and $68,500,000, respectively. Based upon the level
of historical taxable income and projections for future taxable income over the
periods which the deferred tax assets are deductible, a valuation allowance has
been established for the Company's net deferred tax assets as of December 31,
1997 and 1998.

   At December 31, 1998, the Company has net operating loss carryforwards for
federal income tax purposes of approximately $82,600,000, which are available
to offset future federal taxable income, if any, through 2018. In addition, the
Company has alternative minimum tax credit carryforwards of approximately
$249,000 which are available to reduce future federal regular income taxes, if
any, over an indefinite period.

(10) Restructuring Plan

   In the fourth quarter of 1998, the Company recorded provisions of $2,060,770
for restructuring expenses. These expenses are included in selling, general,
and administrative expenses in the combined financial statements. Included in
this charge are severance and other costs of $1,938,501 and costs related to
losses on contractual obligations of $122,269. The Company's restructuring plan
commitments in 1998, which are expected to be fully completed in 1999, included
initiatives to cease all activities related to the strategy to create a multi-
service network, including terminating all employees assigned specifically to
this task and abandoning all contractual obligations. The restructuring plan
also committed to terminate and pay severance to certain personnel. As part of
the restructuring initiative, 130 employees have been eliminated from the
Company as of December 31, 1998. The remaining restructuring accrual of
$1,256,628 at December 31, 1998 is included with accrued expenses in the
combined financial statements.

(11) Commitments and Contingencies

 Commitments with Telecommunications Companies

   The Company has a $3,000,000 usage commitment with MFS/WorldCom in
Frankfurt, Germany, to use MFS/WorldCom's fiber-optic network in its delivery
of telecommunications services. This agreement began on September 5, 1997 and
extends through June 30, 1999. A charge to cost of revenues of $2,150,496 was
recognized by the Company for a shortfall in the usage commitment during
December 1998.

   The Company also has a two-year minimum usage commitment of $55,000,000 with
WorldCom which began on May 1, 1998.

   The Company has an agreement with Epoch Networks, Inc. for internet
services, with a minimum usage commitment of $875,000 over the next two years.
This agreement began June 1, 1998. A charge to cost of revenues of $875,000 was
recognized by the Company for a shortfall in the usage commitment during
December 1998.

   Shortfalls in usage commitments, if any, are recorded as cost of revenues in
the period identified.

 Letters of Credit

   The Company has outstanding irrevocable letters of credit in the amount of
$418,520 as of December 31, 1998 with certain lessors and carriers. These
letters of credit, which have expiration dates from March 15, 1999 through June
15, 1999, collateralize the Company's obligations for lease commitments and
network usage on

the carriers' networks. The fair value of these letters of credit is estimated
to be the same as the contract values based on the nature of the arrangement
with the issuing banks.

 Retirement Plan

   Effective January 1, 1996, the Company adopted the Telegroup, Inc. 401(k)
Retirement Savings Plan (the 401(k) Plan). The 401(k) Plan is a defined
contribution plan covering all employees of the Company who have one year of
service and have attained the age of twenty-one. Participants may contribute up
to 15% of their base pay in pretax dollars. The Company will match employee
contributions on a discretionary basis. Vesting in Company contributions is
100% after five years in the 401(k) Plan. The Company made no contributions to
the 401(k) Plan in 1996, 1997 and 1998.

 Litigation

   The Company is a party to certain litigation which has arisen in the
ordinary course of business. The most significant of these is described below.

   Subsequent to December 31, 1998, the Company was contacted by Cygnus
Telecommunications Technology (Cygnus) asserting that the Company has infringed
upon its patent rights. Cygnus is currently seeking relief from the automatic
stay provision of the Bankruptcy Code (see note 1) to proceed with the
infringement suit asserting an administrative claim of $1,200,000 against the
Company. While it is not possible to predict with certainty the outcome of the
litigation pending against the Company, it is the opinion of management that
the ultimate disposition of these matters will not have a material adverse
effect on the financial statements of the Company.

 Other Commitments

   On August 3, 1998, the Company entered into a Construction and Maintenance
Agreement (C&MA) to build the Japan-U.S. Cable Network, an under-sea cable
system that will connect Japan and the U.S. by mid-year 2000. Under the C&MA,
the Company is committed to pay approximately $2,200,000 for ownership of its
0.17% share of this trans-Pacific cable over the next two years. The Company
does not intend to make any future payments on this agreement.

$1,000,000 was to be issued. On August 29, 1998, the agreement was amended.

                     INFORMATION NOT REQUIRED IN PROSPECTUS

Item 20. Indemnification of Directors and Officers

   Section 145 of the DGCL permits each Delaware business corporation to
indemnify its directors, officers, employees and agents against liability for
each such person's acts taken in his or her capacity as a director, officer,
employee or agent of the corporation if such actions were taken in good faith
and in a manner which he or she reasonably believed to be in or not opposed to
the best interests of the corporation, and with respect to any criminal action,
if he or she had no reasonable cause to believe his or her conduct was
unlawful. Article X of our Amended and Restated By-Laws provides that we, to
the full extent permitted by Section 145 of the DGCL, shall indemnify all of
our past and present directors and may indemnify all of our past or present
employees or other agents. To the extent that a director, officer, employee or
agent of our's has been successful on the merits or otherwise in defense of any
action, suit or proceeding referred to in such Article X, or in defense of any
claim, issue or matter therein, he or she shall be indemnified by us against
actually and reasonably incurred expenses in connection therewith. Such
expenses may be paid by us in advance of the final disposition of the action
upon receipt of an undertaking to repay the advance if it is ultimately
determined that such person is not entitled to indemnification.

   As permitted by Section 102(b)(7) of the DGCL, Article 11 of our Amended and
Restated Certificate of Incorporation provides that no director shall be liable
to us for monetary damages for breach of fiduciary duty as a director, except
for liability

     (i) for any breach of the director's duty of loyalty to us or our
  stockholders,

     (ii) for acts or omissions not in good faith or which involve
  intentional misconduct or a knowing violation of law,

     (iii) for the unlawful payment of dividends on or redemption of our
  capital stock or

     (iv) for any transaction from which the director derived an improper
  personal benefit.

   We have obtained a policy insuring us and our directors and officers against
certain liabilities, including liabilities under the 1933 Act.

   Pursuant to Section 5(h) of the TresCom merger agreement, we will provide
each individual who served as a director or officer of TresCom at any time
prior to the effective time of the TresCom merger with liability insurance for
a period of six years after the effective time, having no less favorable
coverage than any applicable insurance of TresCom in effect immediately prior
to the effective time; provided, however, if the existing liability insurance
expires, or is terminated or canceled by the insurance carrier during such six-
year period, the company which survived the merger will use its best efforts to
obtain as much liability insurance as can be obtained for the remainder of such
period for a premium not in excess (on an annualized basis) of 150% of the last
annual premium paid prior to the date of the merger agreement.

Item 22. Undertakings

   Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities
Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
registrant of expenses incurred or paid by a director, officer or controlling
person of the registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the registrant will, unless in
the opinion of counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Securities
Act and will be governed by the final adjudication of such issue.

   The undersigned registrant hereby undertakes: (1) to file, during any period
in which offers or sales are being made, a post-effective amendment to this
registration statement: (i) to include any prospectus required by Section
10(a)(3) of the Securities Act of 1933; (ii) to reflect in the prospectus any
facts or events arising after the effective date of the registration statement
(or the most recent post-effective amendment thereof) which, individually or in
the aggregate, represent a fundamental change in the information set forth in
the registration statement. Notwithstanding the foregoing, any increase or
decrease in volume of securities offered (if the total dollar value of
securities offered would not exceed that which was registered) and any
deviation from the low or high and of the estimated maximum offering range may
be reflected in the form of prospectus filed with the Commission pursuant to
Rule 424(b) if, in the aggregate, the changes in volume and price represent no
more than 20 percent change in the maximum aggregate offering price set forth
in the "Calculation of Registration Fee" table in the effective registration
statement; and (iii) to include any material information with respect to the
plan of distribution not previously disclosed in the registration statement or
any material change to such information in the registration statement; (2)
that, for the purpose of determining any liability under the Securities Act,
each such post-effective amendment shall be deemed to be a new registration
statement relating to the securities offered therein, and the offering of such
securities at that time shall be deemed to be the initial bona fide offering
thereof; and (3) to remove from registration by means of a post-effective
amendment any of the securities being registered which remain unsold at the
termination of the offering.

   We consent to the use of our report on the combined financial statements of
Telegroup, Inc. and certain subsidiaries included herein and to the reference
to our firm under the heading "Experts" in this Post-Effective Amendment No.1
to Registration Statement No. 333-76965.

   Our report dated July 9, 1999, contains an explanatory paragraph that states
that the Company has filed for protection under Chapter 11 of the United States
Bankruptcy Code due to significant financial and liquidity problems. These
circumstances raise substantial doubt about its ability to continue as a going
concern. The financial statements do not include any adjustments that might
result from the outcome of this uncertainty.
