                                  THE COMPANY
 
OVERVIEW
 
  Primus is a facilities-based global telecommunications company that offers
international and domestic long distance and other telecommunications services
to business, residential and carrier customers in North America and selected
markets within the Asia-Pacific region and Europe. Primus has expanded its
geographic presence in the Caribbean, Central America and South America
(collectively "Latin America") through its recent acquisition of TresCom, which
provides international long distance service primarily for calls originating in
the United States. The Company seeks to capitalize on the increasing demand for
high-quality international telecommunications services resulting from the
globalization of the world's economies and the worldwide trend toward
telecommunications deregulation. Primus provides these services over its global
intelligent telecommunications network (the "Network"), which includes (i) ten
international gateway switches in the United States, Australia, Canada, Puerto
Rico and the United Kingdom, (ii) four domestic switches in Australia, (iii) a
switching platform in Japan and (iv) both owned and leased transmission
capacity on undersea and land-based fiber optic cable systems. The Network,
along with resale arrangements and foreign carrier agreements, allows the
Company to offer quality service to its approximately 275,000 customers.
 
  Primus is a full-service carrier and has licenses and operations in the
United States, Australia, the United Kingdom, Japan and Canada, enabling it to
complete calls to more than 230 countries. The United States, Australia and the
United Kingdom are the most deregulated countries within the Company's service
regions (the "Service Regions"), which include North America, the Asia-Pacific
region, Europe and, with the consummation of the TresCom Merger, Latin America.
The United States, Australia and the United Kingdom will serve as regional hubs
for Primus's intended expansion into additional markets as worldwide
deregulation of telecommunications markets continues. During the years ended
December 31, 1996 and 1997, and the three months ended March 31, 1998, Primus
had net revenue of $173.0 million, $280.2 million and $80.1 million,
respectively. After giving pro forma effect to the TresCom Merger and the
TelePassport/USFI Acquisition, for the year ended December 31, 1997, the
Company would have had net revenue of $448.9 million and, after giving pro
forma effect to the TresCom Merger, for the three months ended March 31, 1988
the Company would have had net revenue of $114.7 million.
 
  The Company primarily targets, on a retail basis, small- and medium-sized
businesses and ethnic residential customers with significant international long
distance traffic and, on a wholesale basis, other telecommunications carriers
and resellers with substantial international traffic. The Company provides a
broad array of competitively priced telecommunications services, including
international and domestic long distance services and private networks,
reorigination services, prepaid and calling cards and toll-free services, as
well as local, data, Internet and cellular services in Australia. The Company
markets its services through a variety of channels, including through its
direct sales force and independent agents, and through direct marketing.

NETWORK
 
  The Company has constructed and is expanding the Network to reduce and
control costs, improve service reliability and increase flexibility to
introduce new products and services. Management believes that, as the volume of
telecommunications traffic carried on the Network increases, the Company should
continue to improve its profitability as it more fully utilizes its Network
capacity and realizes economies of scale. As customer demand justifies the
capital investment, Primus will seek to expand the Network through additional
investment in undersea and domestic fiber optic cable systems, international
gateway and domestic switching facilities, and international satellite earth
stations. Major components of the Network include the following:
 
  Switches. Since December 31, 1996, when the Company operated one
international gateway switch in Washington, D.C., the Network has grown to
consist of 14 switches, including ten international gateway switches (New York,
Los Angeles, Washington, D.C., Toronto, Vancouver, London and Sydney, and as a
result of the recently completed TresCom Merger, Fort Lauderdale, New York City
and Guaynabo, Puerto Rico) and four domestic switches (Adelaide, Brisbane,
Melbourne and Perth), and a switching platform in Japan. The Company also has
15 points of presence ("Pops") in additional markets within its Service
Regions. The Company's international gateway switches will serve as the base
for its global expansion of the Network into new countries when customer demand
justifies such investment and as regulatory rules permit the Company to compete
in new markets. The Company is currently installing an additional international
gateway switch in Frankfurt, Germany and, by the end of 1999, intends to add up
to three switches in North America, two switches in Europe, one switch in the
Asia-Pacific region, and three switches in Latin America.
 
  Transmission Capacity. The Company owns and leases transmission capacity
which connects its switches to each other and to the networks of other
international and domestic telecommunications carriers. The Company's ownership
interests consist of Minimum Assignable Ownership Units ("MAOUs") and
indefeasible rights of use ("IRUs") in 12 undersea fiber optic cable systems,
including the CANTAT-3, TAT-12/TAT-13, TPC-5 and Gemini systems. As a result of
the recently completed TresCom Merger, the Company has acquired additional
MAOUs and IRUs in 11 cable systems, including the Americas 1, Columbus 2, PTAT-
1 and Taino Carib systems. The Company expects to continue to acquire
additional capacity on both existing and future international and domestic
fiber optic cable systems as anticipated customer demand justifies such
investments.
 
  Foreign Carrier Agreements. In selected countries where competition with the
traditional incumbent post, telephone and telegraph operators ("PTTs") is
limited or is not currently permitted, the Company has entered into foreign
carrier agreements with PTTs or other service providers which permit the
Company to carry traffic into and receive return traffic from these countries.
The Company has existing foreign carrier agreements with PTTs in Cyprus,
Greece, Honduras, India, Iran, Italy and New Zealand, and additional carrier
agreements with foreign service providers in five other countries. As a result
of the recently completed TresCom Merger, the Company has acquired 27
additional foreign carrier agreements, providing access to various countries in
Latin America.
 
STRATEGY
 
  Primus's objective is to become a leading global provider of international
and domestic long distance voice, data and other services in its Service
Regions. Key elements of Primus's strategy to achieve this objective include:
 
  .  Focus on Customers with Significant International Long Distance
     Usage. The Company's primary focus is providing telecommunications
     services, on a retail basis, to small- and medium-sized businesses with
     significant international long distance traffic, to ethnic residential
     customers and, on a wholesale basis, to other telecommunications
     carriers and resellers with international traffic. The Company believes
     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.
 
                                       2
<PAGE>
 
 
  .  Pursue Early Entry into Selected Deregulating Markets. The Company seeks
     to be an early entrant into selected deregulating telecommunications
     markets where it believes there is significant demand for international
     long distance services as well as substantial growth and profit
     potential. The Company believes that early entrance into deregulating
     markets provides it with competitive advantages as it develops sales
     channels, establishes a customer base, hires personnel experienced in
     the telecommunications industry and achieves name recognition, prior to
     the entry into these markets of a large number of competitors. The
     Company focuses its expansion efforts on major metropolitan areas with
     high concentrations of potential customers with international traffic.
 
  .  Expand Global Intelligent Network. Primus expects that continued
     strategic development of the Network will lead to reduced transmission
     and other operating costs as a percentage of net revenue, reduced
     reliance on other carriers and more efficient network utilization. The
     Company owns and operates its own switching facilities, and purchases
     fiber optic cable capacity on an end-to-end basis when current and
     expected traffic levels justify such investment.
 
  .  Deliver Quality Services at Competitive Prices. Management believes that
     the Company delivers high quality services at competitive prices and
     provides a high level of customer service. The Company intends to
     maintain a low cost structure in order to offer its customers
     international and domestic long distance services priced below those of
     major carriers in the Service Regions. In addition, the Company intends
     to maintain strong customer relationships through the use of trained and
     experienced sales and service representatives, and through the provision
     of customized billing services.
 
  .  Expand Service Offerings as Markets Deregulate. The Company typically
     enters markets which are in the initial stages of deregulation by first
     providing international long-distance services and, as the market
     deregulates further, expanding its portfolio of service offerings within
     the particular market. Management believes that international long
     distance generally offers attractive margins in markets in the early
     stages of deregulation and provides a platform for capturing customers
     for additional services. Subsequent additions to service offerings
     include, among other services, domestic long distance, data and Internet
     access.
 
  .  Growth through Selected Acquisitions and Strategic Investments. As part
     of its business strategy, the Company frequently evaluates potential
     acquisitions, joint ventures and strategic investments. The Company
     views acquisitions, joint ventures and strategic investments as a means
     to enter additional markets and expand its operations within existing
     markets, thereby facilitating an acceleration of its business plan.
     Potential candidates include voice and data service providers with an
     established customer base, complementary operations, telecommunications
     licenses, experienced management or network facilities in countries into
     which the Company seeks to enter.
 
                              RECENT DEVELOPMENTS
 
  TresCom Merger. On June 9, 1998, pursuant to an Agreement and Plan of Merger
(as amended, the "Merger Agreement"), the Company acquired all of the
outstanding shares of TresCom, a facilities-based long distance
telecommunications carrier focused on international long distance traffic
originating in the United States and terminating in Latin America. The TresCom
Merger provides Primus with accelerated entry into the Latin American
international long distance markets and expands the scope and coverage of the
Network, thereby providing additional opportunities to migrate traffic onto the
Network, resulting in better utilization of the Network. The Company believes
that, in addition to providing transmission facilities, the TresCom Merger adds
foreign carrier agreements, direct connections to foreign telecommunications
carriers and experienced management, enabling the combined Company to realize
synergies in sales, marketing and administration.

  TresCom markets wholesale telecommunications services to other long distance
carriers who utilize the TresCom network to transmit international calls to
Latin America. TresCom's customers also include businesses with sales or
operations in Latin America, as well as the growing Hispanic population in the
United States. For the years ended December 31, 1995, 1996 and 1997, TresCom
had revenue of $102.6 million, $139.6 million and $157.6 million, respectively.
Pursuant to the Merger Agreement, each of the approximately 12.7 million
outstanding shares of TresCom common stock were exchanged for shares of
Primus's common stock ("Common Stock") at an exchange ratio equal to 0.6147.
See "Recent Developments--TresCom Merger" and "Business--TresCom."
 
  Other Acquisitions and Investments. In March 1998, the Company purchased a
controlling interest in Hotkey Internet Services Pty., Ltd. ("Hotkey"), an
Australia-based Internet service provider, for a cash purchase price of
approximately $1.3 million (the "Hotkey Investment"). Thereafter, in April
1998, the Company acquired all of the outstanding stock of Eclipse
Telecommunications Pty. Ltd. ("Eclipse"), an Australia-based data
communications service provider, for a purchase price of approximately $2.5
million comprised of cash and shares of Common Stock (the "Eclipse
Acquisition"). The combination of these two transactions, together with the
Company's existing Australian operations, positions the Company to offer a
complete range of telecommunications services to corporate customers in
Australia, including fully integrated voice and data networks, as well as
Internet access. See "Recent Developments--Hotkey Investment" and "--Eclipse
Acquisition."
 
                               ------------------
 
  As of June 29, 1998, Primus had an equity market capitalization of
$559,052,316 million, based upon a closing price of $20 1/16 per share and
approximately 27,865,536 shares of Common Stock outstanding (including shares
of Common Stock issued pursuant to the recently completed TresCom Merger).

                         ISSUANCE OF THE INITIAL NOTES
 
  The Initial Notes were issued in an offering to the Initial Purchasers (the
"Offering") of an aggregate of $150.0 million in principal amount of the
Initial Notes pursuant to a Purchase Agreement, dated May 14, 1998 (the
"Purchase Agreement") among the Company and the Initial Purchasers. The net
proceeds of the Offering, after deducting discounts and commissions and
offering expenses, were approximately $145.0 million and were received by the
Company on May 19, 1998 (the "Closing Date"). The Company intends to use the
net proceeds of the Offering to fund capital expenditures to expand and develop
the Company's Network. 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. The Company and the Initial Purchasers
also entered into the Registration Rights Agreement, pursuant to which the
Company granted certain registration rights for the benefit of the holders of
the Initial Notes. The Exchange Offer is intended to satisfy certain of the
Company's obligations under the Registration Rights Agreement with respect to
the Initial Notes. See "The Exchange Offer--Purpose and Effect."

                         DESCRIPTION OF EXCHANGE NOTES
 
  The Initial Notes were issued under an indenture, dated as of May 19, 1998
(the "Indenture"), between the Company and the Trustee. The Exchange Notes will
be issued under the Indenture as it relates to the Exchange Notes. The form and
terms of the Exchange Notes will be identical in all material respects to the
form and terms of the Initial Notes, except that (i) the Exchange 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 Exchange Notes will not be entitled to Liquidated Damages otherwise
payable under the terms of the Registration Rights Agreement in respect of
Initial Notes held by such holders during any period in which a Registration
Default is continuing, and (iii) holders of Exchange Notes will not be, and
upon the consummation of the Exchange Offer Holders of 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 delivery of Exchange Notes by the Company to the
Registrar under the 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. See "The Exchange Offer--
Termination of Certain Rights" and "--Procedures for Tendering Initial Notes"
and "Description of Exchange Notes."
 
Issuer........................  Primus Telecommunications Group, Incorporated
 
Exchange Notes Offered........  $150,000,000 in aggregate principal amount of 9
                                7/8% Senior Notes due 2008.
 
Maturity......................  May 15, 2008.
 
Interest Payment Dates........  May 15 and November 15, commencing on November
                                15, 1998.
 
Ranking.......................  The indebtedness evidenced by the Exchange
                                Notes will rank senior in right of payment to
                                any existing and future obligations of the
                                Company expressly subordinated in right of
                                payment to the Exchange Notes and will be pari
                                passu in right of payment with all other
                                existing and future senior unsecured
                                obligations of the Company including trade
                                payables. As of March 31, 1998, after giving
                                pro forma effect to the Offering and the
                                application of the net proceeds thereof, the
                                Company (on a consolidated basis) would have
                                had outstanding approximately $382.2 million of

                                Company is a holding company that conducts its
                                business through its subsidiaries, all existing
                                and future indebtedness and other liabilities
                                and commitments of the Company's subsidiaries,
                                including trade payables, will be effectively
                                senior to the Exchange Notes. As of March 31,
                                1998, the Company's consolidated subsidiaries
                                had outstanding aggregate liabilities of
                                approximately $101.0 million ($132.4 million
                                after giving effect to the TresCom Merger),
                                which includes $9.5 million of indebtedness
                                ($14.9 million after giving effect to the
                                TresCom Merger).
 
Optional Redemption...........  The Exchange Notes will be redeemable at the
                                option of the Company at any time after May 15,

                                prices set forth herein plus accrued and unpaid
                                interest and Liquidated Damages, if any, to the
                                date of

                                25% of the originally issued aggregate
                                principal amount of Exchange Notes at the
                                redemption price set forth herein plus accrued

                                the Exchange Notes remains outstanding after
                                such redemption. See "Description of Exchange
                                Notes--Optional Redemption."
 
Change of Control.............  Upon the occurrence of a Change of Control,
                                each holder of Exchange Notes will have the
                                right to require the Company to purchase all or
                                any part of such holder's Exchange Notes at a
                                purchase price in cash equal to 101% of the

                                unpaid interest and Liquidated Damages, if any,
                                to the date of purchase. See "Description of
                                Exchange Notes--Repurchase of Notes Upon a
                                Change of Control."
 
Covenants.....................  The Indenture pursuant to which the Exchange
                                Notes will be issued will contain certain
                                covenants that, among other things, limit the
                                ability of the Company and its Restricted
                                Subsidiaries to incur additional indebtedness
                                and issue preferred stock, pay dividends or
                                make other distributions, repurchase Capital

                                Statement") with the Commission with respect to
                                an offer to exchange the Initial Notes (the
                                "Exchange Offer") for a new issue of debt
                                securities of the Company with terms
                                substantially identical to the Notes (the
                                "Exchange Notes") (except that the Exchange
                                Notes will not contain terms with respect to
                                transfer restrictions). In the event that
                                applicable law or Commission policy does not
                                permit the Company to effect the Exchange
                                Offer, the Exchange Offer is not consummated

                                holders of the Initial Notes notify the Company
                                they are not permitted to participate in, or
                                would not receive freely tradable Exchange
                                Notes pursuant to, the Exchange Offer, the
                                Company will use its reasonable best efforts to
                                cause to be declared effective within the
                                prescribed periods a registration statement
                                (the "Shelf Registration Statement") with
                                respect to resale of the Notes and to keep the
                                Shelf Registration Statement continuously

                                Company fails to satisfy these registration
                                obligations, it will be required to pay
                                Liquidated Damages to the holders of the Notes
                                under certain circumstances. See "Description
                                of Exchange Notes--Registration Rights."
 
Absence of a Public Market
for the Exchange Notes........  The Exchange Notes are new securities for which
                                there is currently no established trading      
                                market. The Company does not intend to apply   
                                for listing of the Exchange Notes on any       
                                securities exchange or for quotation through   
                                The Nasdaq Stock Market. Accordingly, there can
                                be no assurance as to the development or       
                                liquidity of any market for the Exchange Notes.

     Notes, less discounts, commissions and expenses of the Offering payable by
     the Company, and the application of the net proceeds therefrom, as if they
     occurred on January 1, 1998.
 (3) Net revenue is after provision for bad debt.
 (4) Pro forma interest expense includes interest expense on the Notes and
     amortization of deferred financing costs.
 (5) The ratio of earnings to fixed charges is computed by dividing pre-tax
     income from operations before fixed charges (other than capitalized
     interest) by fixed charges. Fixed charges consist of interest charges,
     whether expensed or capitalized, and that portion of rental expense the
     Company believes to be representative of interest. For the years ended
     December 31, 1995, 1996 and 1997, and for the three months ended March 31,
     1997 and 1998, earnings were insufficient to cover fixed charges by $2.4
     million, $8.6 million, $36.4 million, $5.1 million and $12.3 million,
     respectively. On a pro forma basis for the year ended December 31, 1997
     and for three months ended March 31, 1998, earnings were insufficient to
     cover fixed charges by $76.5 million and $21.7 million, respectively.
 (6) Consists primarily of net revenue from operations in the United States for
     all periods prior to 1997. Net revenue for 1997 and for the three months
     ended March 31, 1998 reflects commencement of operations in Canada in
     April 1997.
 (7) Consists solely of net revenue from operations in Australia for 1996. Net
     revenue for 1997 and for the three months ended March 31, 1998 reflects
     commencement of operations in Japan in October 1997.
 (8) Consists solely of net revenue from operations in the United Kingdom.
 (9) As used herein, "EBITDA" is defined as net income or loss plus
     depreciation expense, amortization expense, interest expense and income
     taxes, minus extraordinary income and gains, if any, and plus
     extraordinary losses, if any. 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 herein to provide
     additional information regarding the ability of Primus to meet its future
     debt service, capital expenditures and working capital requirements.
     EBITDA is not necessarily a measure of Primus's ability to fund its cash
     needs and is not necessarily comparable to similarly titled measures of
     other companies.
(10) Capital expenditures include assets acquired, committed to be acquired and
     leased under capital lease agreements.
(11) Gives pro forma effect to the TresCom Merger and the sale of the Initial
     Notes in the Offering, less discounts, commissions and expenses of the
     Offering payable by the Company, and the application of the net proceeds
     therefrom, as if they had occurred on March 31, 1998.

                                 RISK FACTORS
 
  Prospective investors should carefully consider the following risk factors,
in addition to the other information contained elsewhere in this Offering
Memorandum, in evaluating whether to purchase the Notes offered hereby.
 
SUBSTANTIAL INDEBTEDNESS; LIQUIDITY
 
  The Company has substantial indebtedness. As of March 31, 1998, on a pro
forma basis after giving effect to the Offering, the Company's total
indebtedness would have been approximately $382.2 million ($387.6 million
after giving pro forma effect to the TresCom Merger). For the three months
ended March 31, 1998, after giving pro forma effect to the Offering, the
Company's consolidated EBITDA would have been approximately negative $4.0
million (negative $6.1 million after giving pro forma effect to the TresCom
Merger), and its earnings would have been insufficient to cover fixed charges
by approximately $16.1 million ($21.7 million after giving pro forma effect to
the TresCom Merger). The Indenture limits, but does not prohibit, the
incurrence of additional indebtedness by the Company and certain of its
subsidiaries and does not limit the amount of indebtedness that can be
incurred to finance the cost of telecommunications equipment. The Company
anticipates that it and its subsidiaries will incur additional indebtedness in
the future. See "Description of Notes."
 
  The level of the Company's indebtedness could have important consequences to
holders of the Notes, including the following: (i) the debt service
requirements of any additional indebtedness could make it more difficult for
the Company to make payments of interest on its outstanding debt, including
the Notes; (ii) the ability of the Company to obtain any necessary financing
in the future for working capital, capital expenditures, debt service
requirements or other purposes may be limited; (iii) a substantial portion of
the Company's cash flow from operations, if any, must be dedicated to the
payment of principal and interest on its indebtedness and other obligations
and will not be available for use in its business; (iv) the Company's level of
indebtedness could limit its flexibility in planning for, or reacting to,
changes in its business; (v) the Company is more highly leveraged than some of
its competitors, which may place it at a competitive disadvantage; and (vi)
the Company's high degree of indebtedness will make it more vulnerable in the
event of a downturn in its business.
 
  The Company must substantially increase its net cash flow in order to meet
its debt service obligations, and there can be no assurance that the Company
will be able to meet such obligations, including its obligations under the
Notes. If the Company is unable to generate sufficient cash flow or otherwise
obtain funds necessary to make required payments, or if it otherwise fails to
comply with the various covenants under its indebtedness, it would be in
default under the terms thereof, which would permit the holders of such
indebtedness to accelerate the maturity of such indebtedness and could cause
defaults under other indebtedness of the Company. Such defaults could result
in a default on the Notes and could delay or preclude payments of interest or
principal thereon.
 
HISTORICAL AND FUTURE OPERATING LOSSES; NEGATIVE EBITDA; NET LOSSES
 
  Since inception through March 31, 1998, the Company had negative cash flow
from operating activities of $41.3 million and negative EBITDA of $35.9
million. In addition, the Company incurred net losses in 1995, 1996, 1997 and
the three months ended March 31, 1998, of $2.4 million, $8.8 million, $36.2
million and $12.3 million, respectively, and had an accumulated deficit of
approximately $60.3 million as of March 31, 1998. On a pro forma basis, after
giving effect to the Offering, the TelePassport/USFI Acquisition and the
TresCom Merger, for the year ended December 31, 1997, the Company would have
had a net loss of $76.5 million. On a pro forma basis, after giving effect to
the Offering and the TresCom Merger, for the three months ended March 31,
1998, the Company would have had a net loss of $21.7 million. Although the
Company has experienced net revenue growth in each of its last 13 quarters,
such growth should not be considered to be indicative of future net revenue
growth, if any. The Company expects to continue to incur additional operating
losses, negative EBITDA and negative cash flow from operations as it expands
its operations and continues to build-out and upgrade the Network. There can
be no assurance that the Company's net revenue will grow or be sustained in
future periods or that it will be able to achieve or sustain profitability or
generate positive cash flow from operations in any
 
                                      14
<PAGE>
 
future period. If the Company cannot achieve and sustain operating
profitability or positive cash flow from operations, it may not be able to
meet its debt service or working capital requirements (including its
obligations with respect to the Notes). See "Selected Financial Data,"
"Unaudited Pro Forma Financial Data" and "Management's Discussion and Analysis
of Financial Condition and Results of Operations."
 
NEED FOR ADDITIONAL FINANCING
 
  The Company will not receive any proceeds from the Exchange Offer. The
Company believes that the net proceeds from the Offering, together with its
existing cash and available capital lease financing (subject to limitations in
the Indenture) will be sufficient to fund the Company's operating losses, debt
service requirements, capital expenditures and other cash needs for its
operations for at least the next 18 to 24 months. The Company is continually
evaluating the expansion of the Network and plans to accelerate its investment
in international and domestic fiber optic cable capacity and other
transmission facilities. In addition, the Company expects to make additional
investments in the TresCom network in order to expand its services in Latin
America. In order to fund these additional cash requirements, including the
expansion of the combined Network, Primus anticipates that it will be required
to raise a significant amount of cash in excess of its existing cash and cash
equivalents and the proceeds from the Offering. Consequently, the Company
expects to raise additional capital from public or private equity or debt
sources to meet its new financing needs, including for the continued buildout
of the Network. Additionally, if the Company's plans or assumptions change
(including those with respect to the development of the Network, the scope of
its operations and its operating cash flow), if its assumptions prove
inaccurate, if it consummates additional investments or acquisitions, if it
experiences unexpected costs or competitive pressures, or if existing cash and
any other borrowings prove to be insufficient, the Company may be required to
seek additional capital sooner than expected. Both the Indenture and the
indenture (the "1997 Indenture") relating to the 1997 Senior Notes (as
defined) contain certain restrictive covenants that will affect, and in many
respects will significantly limit or prohibit, among other things, its ability
to incur additional indebtedness and to create liens. See "Description of
Notes." If the Company is able to raise additional funds through the
incurrence of debt, and it does so, it would likely become subject to
additional restrictive financial covenants. In the event that the Company is
unable to obtain such additional capital or is unable to obtain such
additional capital on acceptable terms, it may be required to reduce the scope
of its expansion, which could adversely affect its business, results of
operations and financial condition, its ability to compete and its ability to
meet its obligations on the Notes. There can be no assurance that the Company
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 Network expansion or otherwise. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations."
 
HOLDING COMPANY STRUCTURE; RELIANCE ON SUBSIDIARIES FOR DISTRIBUTIONS TO REPAY
NOTES
 
  Primus is a holding company, the principal assets of which are its operating
subsidiaries. As a holding company, the Company's sources of funds to meet its
cash needs, including payment of expenses and principal and interest on the
Notes, are dividends, intercompany loans and other permitted payments from its
direct and indirect subsidiaries, as well as its own credit arrangements. The
subsidiaries of the Company are legally distinct from the Company and have no
obligation, contingent or otherwise, to pay amounts due with respect to the
Notes or to make funds available for such payments and will not guarantee the
Notes. Additionally, many of the Company's subsidiaries are organized in
jurisdictions outside the United States, including Australia, Canada, the
United Kingdom and Japan. The ability of the Company's operating subsidiaries
to pay dividends, repay intercompany loans or make other distributions to the
Company may be restricted by, among other things, the availability of funds,
the terms of various credit arrangements entered into by such operating
subsidiaries, as well as statutory and other legal restrictions, and such
payments may have adverse tax consequences. The failure to pay any such
dividends, repay intercompany loans or make any such other distributions would
restrict the Company's ability to repay the Notes and its ability to utilize
cash flow from one subsidiary to cover shortfalls in working capital at
another subsidiary, and could otherwise have a material adverse effect upon
the Company's business, financial condition and results of operations.
 
                                      15
<PAGE>
 
  Because the Company is a holding company that conducts its business through
its subsidiaries, claims of creditors of such subsidiaries will generally have
priority over the assets of such subsidiaries over the claims of the Company
and the holders of the Company's indebtedness. Accordingly, the Notes will be
effectively subordinated to all existing and future indebtedness and other
liabilities and commitments of the Company's subsidiaries, including trade
payables. As of March 31, 1998, the Company's consolidated subsidiaries had
outstanding aggregate liabilities of approximately $101.0 million ($132.4
million after giving pro forma effect to the TresCom Merger). Any right of the
Company to receive assets of any subsidiary upon the liquidation or
reorganization of such subsidiary (and the consequent rights of the holders of
the Notes to participate in those assets) will be effectively subordinated to
the claims of such subsidiary's creditors, except to the extent that the
Company is itself recognized as a creditor, in which case the claims of the
Company would still be subordinate to any security in the assets of such
subsidiary and any indebtedness of such subsidiary that is senior to that held
by the Company. In addition, holders of such indebtedness of the Company would
have a claim on the assets securing such indebtedness that is prior to the
holders of the Notes and would have a claim that is pari passu with the
holders of the Notes to the extent such security did not satisfy such
indebtedness. The Company has no significant assets other than the stock of
its subsidiaries and it is expected that, if the Company were to enter into a
bank credit facility or similar arrangement, the stock of the subsidiaries
would be pledged to secure any such credit facility or arrangement.
 
LIMITED OPERATING HISTORY
 
  The Company and TresCom have limited operating histories and limited
experience in operating their respective businesses. Primus was founded in
February 1994 and began generating operating revenues in March 1995. Axicorp,
the Company's principal operating subsidiary, was acquired in March 1996.
TresCom was founded in December 1993. In addition, the Company intends to
enter markets where it has limited or no operating experience such as, due to
the recently completed TresCom Merger, Latin America. Accordingly, there can
be no assurance that the Company's future operations will generate operating
or net income, and the Company's prospects must therefore be considered in
light of the risks, expenses, problems and delays inherent in establishing a
new business in a rapidly changing industry. See "Selected Financial Data,"
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" and "Unaudited Pro Forma Financial Data."
 
DEVELOPMENT OF THE NETWORK; MIGRATION OF TRAFFIC ONTO THE NETWORK
 
  The long-term success of the Company is dependent upon its ability to
design, implement, operate, manage and maintain the Network, activities in
which its management has limited experience, and its ability to generate and
maintain traffic on the Network. By expanding the Network, the Company will
incur additional fixed operating costs that typically are, particularly with
respect to international transmission lines, in excess of the revenue
attributable to the transmission capacity funded by such costs until the
Company generates additional traffic volume for such capacity. There can be no
assurance that the Company will generate sufficient traffic to economically
utilize its capacity or that the Network can be completed in a timely manner
or operated efficiently. Any failure in design, or any failure to implement,
operate, manage or maintain the Network, or generate or maintain traffic,
could have a material adverse effect on the Company's business, results of
operations and financial condition. In addition, the Company intends to expand
the Network as more countries deregulate their telecommunications industries,
which will require the Company to acquire additional licenses and equipment.
There can be no assurance that the Company will be able to obtain the licenses
or purchase the necessary equipment on favorable terms or, if it does, that
the development of the Network in these countries will be successful. See
"Business--Strategy" and "--Network."
 
MANAGING RAPID GROWTH
 
  The Company's strategy of continuing its growth and expansion has placed,
and is expected to continue to place, a significant strain on its management,
operational and financial resources, and increased demands on its systems and
controls. The Company is continuing to develop the Network by adding switches
and fiber optic
 
                                      16

cable, expanding its operations within North America, the Asia-Pacific region
and Europe, and when business and/or regulatory conditions warrant, expanding
into selected additional markets such as, due to the recently completed
TresCom Merger, Latin America. In order to manage its growth effectively, the
Company must continue to implement and improve its operational and financial
systems and controls, purchase and utilize other transmission facilities, and
expand, train and manage its employee base. Inaccuracies in forecasts of
traffic could result in insufficient or excessive transmission facilities and
disproportionate fixed expenses. There can be no assurance that the Company
will be able to further develop its 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 the Company proceeds with its
development, there will be additional demands on its customer support, billing
and management information systems and support, sales and marketing and
administrative resources and network infrastructure. There can be no assurance
that the Company's operating and financial control systems and infrastructure
will be adequate to maintain and effectively manage future growth. The failure
to continue to upgrade the administrative, operating and financial control
systems or the emergence of unexpected expansion difficulties could materially
adversely affect the Company's business, results of operations and financial
condition. See "--Dependence on Effective Information Systems; Year 2000
Problem" and "--Acquisition and Strategic Investment Risks."
 
ACQUISITION AND STRATEGIC INVESTMENT RISKS
 
  A key element of the Company's business strategy is to acquire or make
strategic investments in assets and businesses that are complementary to the
Company's operations, and a major portion of the Company's growth in recent
years has resulted from such acquisitions. These acquisitions involve certain
financial and operational risks. Financial risks include the possible
incurrence of indebtedness by the Company in order to effect an acquisition
(subject to the limitations contained in the Indenture) and the consequent
need to service that indebtedness. Operational risks include the possibility
that an acquisition does not ultimately provide the benefits originally
anticipated by management while the Company continues to incur operating
expenses to provide the services formerly provided by the acquired company,
and the difficulty of integrating the service offerings, distribution channels
and networks gained through acquisitions and strategic investments with those
of the Company. In addition, if the Company makes a strategic investment by
acquiring a minority interest in a company, the Company may lack control over
the operations and strategy of the business in which the Company invested.
There can be no assurance that such lack of control will not interfere with
the integration of services and distribution channels of the business in which
the Company invested. In addition, there can be no assurance that the Company
will be successful in identifying attractive acquisition and strategic
investment candidates, completing and financing additional acquisitions on
favorable terms, or integrating the acquired businesses or assets into its
own. In carrying out its acquisition and strategic investment strategy, the
Company attempts to minimize the risk of unexpected liabilities and
contingencies associated with acquired businesses through planning,
investigation and negotiation, but such unexpected liabilities may
nevertheless accompany such strategic investments and acquisitions.
 
  For example, achieving the anticipated benefits of the TresCom Merger will
depend in part upon whether the integration of the two companies' businesses
is accomplished in an efficient and effective manner, and there can be no
assurance as to the extent that this will occur, if at all. The combination of
the two companies will require, among other things, integration of the
companies' respective services, technologies, billing and management
information systems, distribution channels and key personnel, and the
coordination of their sales, marketing and development efforts. There can be
no assurance that such integration will be accomplished smoothly or
successfully, if at all. If significant difficulties are encountered 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. There can be no assurance
that the Company will be able to take full advantage of the combined sales
forces' efforts. The integration of operations and technologies following the
TresCom Merger will require the dedication of management and other personnel
which may distract their attention from the day-to-day business of the
Company, the development or acquisition of new technologies, and the pursuit
of other business acquisition opportunities. Failure to accomplish
 
                                      17
<PAGE>
 
successfully the integration and development of the two companies' operations
and technologies could have a material adverse effect on the Company's
business, financial condition and results of operations. In addition, as
commonly occurs with mergers of telecommunications companies, during the pre-
merger and integration phases, aggressive competitors may undertake
initiatives to attract the Company's customers through various incentives
which could have a material adverse effect on the business, results of
operations and financial condition of the Company.
 
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. In more deregulated countries, the industry has
relatively limited barriers to entry 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. The Company
believes that competition in all of its 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 such markets continue to
experience deregulatory influences. This increase in competition could
adversely affect net revenue per minute and gross margin as a percentage of
net revenue. The Company competes primarily on the basis of price
(particularly with respect to its sales to other carriers), and also on the
basis of customer service and its ability to provide a variety of
telecommunications products and services. Prices for long distance calls in
several of the markets in which the Company competes have declined in recent
years and are likely to continue to decrease. There can be no assurance that
the Company will be able to compete successfully in the future.
 
  Many of the Company's competitors are significantly larger than the Company,
have (i) substantially greater financial, technical and marketing resources,
(ii) larger networks, (iii) a broader portfolio of services, (iv) controlled
transmission lines, (v) stronger name recognition and customer loyalty, and
(vi) long-standing relationships with the Company's target customers. In
addition, many of the Company's 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. Such a
strategy, if widely adopted, could have an adverse effect on the Company's
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. The Company's competitors include, among
others: AT&T, MCI, Sprint, WorldCom Network Services, Inc., Frontier
Communications Services, Inc., Pacific Gateway Exchange, Inc., Qwest
Communications Intl., Inc. and LCI International, Inc. in the United States;
Telstra, Optus Communications Pty. Limited, AAPT, World Exchange and GlobalOne
in Australia; British Telecommunications plc, Mercury Communications, AT&T,
WorldCom, GlobalOne, ACC Corporation, Colt, Energis, Esprit Telecom Group, and
RSL Communications in the United Kingdom; Deutsche Telekom, O.tel.o
Communications, Mannesmann ARCOR, Colt, WorldCom, PlusNet, and RSL
Communications in Germany; Stentor, AT&T Canada Long Distance Services Co.,
fONOROLA Inc., Sprint Canada and ACC in Canada; Telmex, the other PTTs in
Latin America, AT&T, MCI and Sprint in Latin America; Kokusai Denshin Denwa
Co., Ltd. ("KDD"), Nippon Telegraph and Telephone Corporation, Japan Telecom,
IDC and a number of second tier carriers such as Cable & Wireless, WorldCom
and ATNet in Japan.
 
  In addition to these competitors, recent and pending deregulation in various
countries may encourage new entrants. For example, the number of competitors
is likely to increase as a result of the new competitive opportunities created
by the World Trade Organization ("WTO"). Under the terms of an agreement under
the WTO (the "WTO Agreement"), the United States and 68 other participating
countries have committed to open their telecommunications markets to
competition starting on January 1, 1998. Further, as a result of the
Telecommunications Act of 1996 (the "1996 Telecommunications Act") in the
United States, once certain conditions are met, the Regional Bell Operating
Companies ("RBOCs") will be allowed to enter the domestic long distance
market, AT&T, MCI and other long distance carriers are allowed to enter the
local telephone
 
                                      18
<PAGE>
 
services market, and any entity (including cable television companies and
utilities) is allowed to enter both the local service and long distance
telecommunications markets. Increased competition in the United States as a
result of the foregoing, and other competitive developments, including entry
by Internet service providers into the long distance market, could have an
adverse effect on the Company's business, results of operations and financial
condition. In addition, with the ongoing deregulation of the Australian
telecommunications market and the granting of additional carrier licenses, the
Company could experience additional competition in the Australian market from
newly licensed telecommunications carriers. 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 increased competition could adversely impact the Company's
ability to expand its customer base and achieve increased revenue growth, and
consequently, could have an adverse effect on its business, results of
operations and financial condition. See "Management's Discussion and Analysis
of Financial Condition and Results of Operations" and "Business--Competition."
 
DEPENDENCE ON TRANSMISSION FACILITIES-BASED CARRIERS
 
  Telephone calls made by the Company's customers primarily are connected
through transmission lines that the Company leases under a variety of
arrangements with other facilities-based long distance carriers, many of which
are, or may become, competitors of the Company. The Company's ability to
maintain and expand its business is dependent upon whether it continues to
maintain favorable relationships with the facilities-based carriers from which
it leases transmission lines. Although the Company believes that its
relationships with carriers generally are satisfactory, the deterioration or
termination of its relationships with one or more of these carriers could have
a material adverse effect upon its cost structure, service quality, Network
diversity, results of operations and financial condition.
 
  Presently, most transmission lines used by the Company are obtained on a
per-call (or usage) basis, subjecting the Company to the possibility of
unanticipated price increases and service cancellations. Currently, usage
rates generally are less than the rates the Company charges its customers for
connecting calls through these lines. To the extent these variable costs
increase, the Company may experience reduced or, in certain circumstances,
negative margins for some services. As its traffic volume increases between
particular international markets, the Company expects to cease using variable
usage arrangements between these markets and enter into fixed monthly or
longer-term leasing arrangements, subject to obtaining any requisite
authority. To the extent the Company does so, and incorrectly projects traffic
volume in a particular geographic area, the Company would experience higher
fixed costs without the increased revenue. Moreover, certain of the vendors
from whom the Company leases transmission lines, including RBOCs and other
Local Exchange Carriers ("LECs") in the United States, currently are subject
to tariff controls and other price constraints which in the future may be
changed. Regulatory proposals are pending that may affect the prices charged
by the RBOCs and other LECs to the Company, which could have a material
adverse effect on the Company's margins, business, financial condition and
results of operations. See "--Potential Adverse Effects of Regulation" and
"Business--Government Regulation."
 
RISKS ASSOCIATED WITH INTERNATIONAL OPERATIONS
 
  A key component of the Company's strategy is planned expansion in
international markets. In many international markets, the existing carrier
controls access to the local networks, enjoys better brand recognition and
brand and customer loyalty, and has significant operational economies,
including a larger backbone network and foreign carrier agreements with other
PTTs and other service providers. Moreover, the incumbent may take many months
to allow competitors to interconnect to its switches within the target market.
Pursuit of international growth opportunities may require significant
investments for an extended period before returns, if any, on such investments
are realized. In addition, there can be no assurance that the Company will be
able to obtain the permits and operating licenses required for it to operate
its own transmission facilities or switches, obtain access to local
transmission facilities or to market, sell and deliver competitive services in
these markets or that such permits and operating licenses, if obtained, will
be obtained in the time currently contemplated by the Company.
 
                                      19
<PAGE>
 
  In addition to the uncertainty as to the Company's ability to expand its
international presence, there are certain risks inherent in doing business on
an international level, such as 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,
which could materially adversely impact the Company's international
operations. A significant portion of the Company's net revenue and expenses is
denominated, and is expected to continue to be denominated, in currencies
other than United States dollars, and changes in exchange rates may have a
significant effect on its results of operations. The Company historically has
not engaged in hedging transactions, and does not currently contemplate
engaging in hedging transactions to mitigate foreign exchange risk. In
addition, the Company's business could be adversely affected by a reversal in
the current trend toward deregulation of telecommunications markets. In
certain countries into which the Company may choose to expand in the future,
the Company may need to enter into joint venture or other strategic
relationships with one or more third parties in order to conduct its
operations (often with the PTT or other dominant carrier in a developing
country). There can be no assurance that such factors will not have a material
adverse effect on the Company's future operations and, consequently, on its
business, results of operations and financial condition, or that the Company
will not have to modify its business practices.
 
DEPENDENCE ON EFFECTIVE INFORMATION SYSTEMS; YEAR 2000 PROBLEM
 
  To complete its billing, the Company must record and process massive amounts
of data quickly and accurately. While the Company believes its management
information system is currently adequate, it will have to grow as the
Company's business expands and to change as new technological developments
occur. The Company believes that the successful implementation and integration
of new information systems and backroom support will be important to its
continued growth, its ability to monitor and control costs, to bill customers
accurately and in a timely fashion and to achieve operating efficiencies.
There can be no assurance that the Company will not encounter delays or cost-
overruns or suffer adverse consequences in implementing these systems. Any
such delay or other malfunction of the Company's management information
systems could have a material adverse effect on its business, financial
condition and results of operations.
 
  The Company is reviewing its computer systems and operations to identify and
determine the extent to which any systems will be vulnerable to potential
errors and failures as a result of the "Year 2000" problem. 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 the Company's
programs that have time-sensitive software may recognize a date using "00" as
the year 1900 rather than the year 2000. This could result in a major system
failure or miscalculations. The management of each operating unit within the
Company is responsible for identifying systems requiring modification or
conversion (both internal systems and those provided by or otherwise available
from outside vendors), and for periodically reporting its progress in meeting
milestones toward compliance. TresCom management has determined that TresCom
will need to modify or replace significant portions of its software so that
its computer systems will function properly with respect to dates in the year
2000 and beyond. The majority of the software which needs to be replaced by
Primus and TresCom is under license from third party software manufacturers
who have indicated that they will provide the necessary upgrades. There can be
no assurance that any such upgrades will be successfully implemented or that
additional steps will not be necessary. A failure of the Company's computer
systems or the failure of the Company's vendors or customers to upgrade
effectively their software and systems for transition to the year 2000 could
have a material adverse effect on the Company's business and financial
condition or results of operations. See "Management's Discussion and Analysis
of Financial Condition and Results of Operations."

RISKS OF INDUSTRY CHANGES AFFECTING COMPETITIVENESS AND FINANCIAL RESULTS
 
  The international telecommunications industry is changing rapidly due to
deregulation, privatization of PTTs, technological improvements, expansion of
telecommunications infrastructure and the globalization of the world's
economies. There can be no assurance that one or more of these factors will
not vary in a manner that could have a material adverse effect on the Company.
In addition, deregulation in any particular market may cause such market to
shift unpredictably. There can be no assurance that the Company will be able
to compete effectively or adjust its contemplated plan of development to meet
changing market conditions.
 
  The telecommunications industry generally is in a period of rapid
technological evolution, marked by the introduction of new product and service
offerings and increasing satellite and undersea cable transmission capacity
for services similar to those provided by the Company. Potential developments
that could adversely affect the Company if not anticipated or appropriately
responded to include improvements in transmission equipment, development of
switching technology allowing voice/data/video multimedia transmission
simultaneously and commercial availability of Internet-based domestic and
international switched voice/data/video services at prices lower than
comparable services offered by the Company. The Company's profitability will
depend on its ability to anticipate, assess and adapt to rapid technological
changes and its ability to offer, on a timely and cost-effective basis,
services that meet evolving industry standards. There can be no assurance that
the Company 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.
 
EFFECTS OF NATURAL DISASTERS
 
  Areas in which the Company conducts its business may be affected by natural
disasters (including hurricanes and tropical storms) as evidenced by Hurricane
Marilyn, which struck certain Caribbean islands, including St. Thomas and
Puerto Rico, in September 1995 and disrupted telecommunications services in
the Caribbean. Hurricanes, tropical storms and other natural disasters could
have a material adverse effect on the Company's business as a result of damage
to the Company's Network facilities or from curtailed telephone traffic
resulting from effects of such events, such as destruction of homes and
businesses.
 
DEPENDENCE ON KEY PERSONNEL
 
  The Company is dependent on the efforts of its management team and its key
technical, marketing and sales personnel, particularly those of K. Paul Singh,
its Chairman and Chief Executive Officer. The loss of services of one or more
of these key individuals, particularly Mr. Singh, could materially and
adversely affect the business of the Company and its future prospects. Primus
has entered into an employment agreement with Mr. Singh, which expires on May
30, 1999. The Company does not maintain any key person life insurance on the
lives of any officer, director or key employee. The Company's future success
will also depend on its ability to attract and retain additional key
management and technical and sales personnel required in connection with the
growth and development of its business. Competition for qualified employees
and personnel in the telecommunications industry 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. There
can be no assurance that the Company will be successful in attracting and
retaining such executives and personnel. The loss of the services of key
personnel, or the inability to attract additional qualified personnel, could
have a material adverse effect on its results of operations, development
efforts and ability to expand.
 
POTENTIAL ADVERSE EFFECTS OF REGULATION
 
  As a multinational telecommunications company, the Company is subject to
varying degrees of regulation in each of the jurisdictions in which it
currently provides, or expects to provide, its services. Local laws and
regulations, and the interpretation of such laws and regulations, differ
significantly among the jurisdictions in which the Company operates. There can
be no assurance that future regulatory, judicial and legislative changes will
not have a material adverse effect on the Company, that domestic or
international regulators or third parties will not raise material issues with
regard to the Company's compliance or noncompliance with applicable
 
                                      21
<PAGE>
 
regulations or that regulatory activities will not have a material adverse
effect on the Company. Certain risks regarding the regulatory framework in the
principal jurisdictions in which the Company provides its services are briefly
described below.
 
  United States. In the United States, the Company's services are subject to
the provisions of the Communications Act of 1934, as amended by the 1996
Telecommunications Act (the "Communications Act"), and the Federal
Communications Commission (the "FCC") regulations thereunder, as well as the
applicable laws and regulations of the various states administered by the
relevant state public service commission ("PSC"). The recent trend in the
United States, for both federal and state regulation of telecommunications
service providers, has been in the direction of reduced regulation. Although
this trend facilitates market entry and competition by multiple providers, it
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 the Company. In addition, the 1996 Telecommunications Act has opened the
United States market to increased competition. There can be no assurance that
future regulatory, judicial and legislative changes in the United States will
not result in a material adverse effect on the Company.
 
  Despite recent trends toward deregulation, the FCC and relevant state PSCs
continue to exercise authority to regulate ownership of transmission
facilities, provision of services and the terms and conditions under which the
Company's services are provided. In addition, the Company is required by
federal and state law and regulations to file tariffs listing the rates, terms
and conditions of the services it provides. Any failure to maintain proper
federal and state tariffs or certification or any finding by the federal or
state agencies that the Company is not operating under permissible terms and
conditions may result in an enforcement action or investigation, either of
which could have a material adverse effect on the Company.
 
  To originate and terminate calls, long distance carriers such as the Company
must purchase "access" from the LECs, including Competitive Local Exchange
Carriers. Access charges represent a significant portion of the Company's cost
of revenue and, generally, such access charges are regulated by the FCC. The
FCC has recently reformed its regulation of LEC access charges to better
account for increasing levels of local competition. Under the new rules, LECs
will be permitted to allow certain volume discounts in the pricing of access
charges. While the import of these new rules is not yet certain, it is
possible that many long distance carriers, including the Company, could be
placed at a significant cost disadvantage to larger competitors.
 
  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.
Such requirements may delay, prevent or deter a change in control of the
Company. The FCC has established and administered a variety of international
service regulations, including the International Settlements Policy ("ISP")
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" accounting rates for such settlement and permissible
exceptions to these policies. The FCC could find that, absent a waiver,
certain terms of the Company's foreign carrier agreements do not meet the
requirements of the ISP or that certain actions do not constitute permissible
deviations from these policies. Although the FCC generally has not issued
penalties in this area, it could, among other things, issue a cease and desist
order or impose fines if it finds that these agreements conflict with the ISP.
The Company does not believe that any such fine or order would have a material
adverse effect on it. The FCC also regulates the nature and extent of foreign
ownership in radio licenses and foreign carrier affiliations of the Company.
 
  Regulatory requirements pertinent to the Company's operations have recently
changed and will continue to change as a result of the WTO 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 the ability of the Company to compete with other service providers, to
continue providing the same services, or to introduce services currently
planned for the future. The impact on the Company's operations of any changes
in applicable regulatory requirements cannot be predicted.
 
                                      22
<PAGE>
 
  Canada. In Canada, telecommunications carriers are regulated generally by
the Canadian regulatory agency known as the Canadian Radio-television and
Telecommunications Commission ("CRTC"). The CRTC has enacted policies and
regulations that affect the Company's ability to successfully compete in the
Canadian marketplace. These policies and regulations include the establishment
of contribution charges (roughly the equivalent of access charges in the
U.S.), deregulation of the international segment of the long-distance market,
limitations on switched hubbing through the United States, international
simple resale ("ISR") and foreign ownership rules for facilities-based
carriers. In addition, Canada has committed in the WTO Agreement to eliminate
a number of barriers to competition, some of which are expected to be
eliminated in October 1998. The regulatory framework for the introduction of
competition in the provision of international services in Canada is currently
under active CRTC review. There can be no assurance that the regulatory
environment ultimately adopted for Canada will allow Primus 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 the Company's competitive position, growth and financial
performance.
 
  Australia. In Australia, the provision of the Company's services is subject
to federal regulation. Two primary instruments of regulation have been the
Telecommunications Act 1991 and federal regulation of anti- competitive
practices pursuant to the Trade Practices Act 1974 (the "Trade Practices
Act"). The regulatory climate changed in July 1997 with the implementation of
the Telecommunications Act 1997 (the "Telecom Act").
 
  The Company is licensed under the Telecom Act to own and operate
transmission facilities in Australia. Under the new regulatory framework, the
Company does not require a carriage license in order to supply carriage
services to the public using network facilities owned by another carrier.
Instead, it 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.
 
  Also, in connection with the Telecom Act, two federal regulatory authorities
now exercise control over a broad range of issues affecting the operation of
the Australian telecommunications industry. The Australian Communications
Authority ("the ACA") regulates matters including the licensing of carriers
and technical matters, and the Australian Competition and Consumer Commission
("the ACCC") has the role of promotion of competition and consumer protection.
As a licensed carrier, the Company is required to comply with its own license
and is under the regulatory control of the ACA and the ACCC. 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 the Company. 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 the Company.
 
  United Kingdom. In the United Kingdom, the provision of the Company's
services is subject to and affected by regulations introduced by the United
Kingdom telecommunications regulatory authority, the Office of
Telecommunications ("Oftel") under the Telecommunications Act of 1984 (the
"United Kingdom Telecommunications Act"). 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 the ability of the Company to conduct its 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 the Company
can charge its customers. The Company's subsidiary, Primus Telecommunications
Limited, holds an ISVR 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
 
                                      23
<PAGE>
 
United Kingdom. There can be no assurance that future changes in regulation
and government will not have a material adverse effect on the Company's
business, results of operations and financial condition.
 
  Japan. The Company's services in Japan are subject to regulation by the
Ministry of Post and Telecommunications (the "Japanese Telecom Ministry")
under the Telecommunications Business Law (the "Japanese Telecom Law"). The
Company has obtained a license as a Special Type II business, which allows it
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. The Company may also provide over
leased lines basic telecommunications services, value-added services and
services to closed user groups. The Company is preparing to apply for a
license to operate as a Type I business, which would allow the Company to
provide telecommunications services using their own facilities. There can be
no guarantee that the Company will be able to obtain any required licenses or
that once it obtains a license, the Japanese regulatory environment will allow
it to provide services in Japan at competitive rates.
 
  Germany. The Company's services in Germany are governed by the German
Telecommunications Act of 1996 (the "German Telecom Act"), 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. Under
the German Telecom Act, the Company must obtain a license if it (i) operates
transmission infrastructure for the provision of telecommunications services
to the public ("Class 3 License"); or (ii) offers voice telephony services to
the public through telecommunications networks operated by the Company ("Class
4 License"). The Company has obtained a Class 4 license and has entered into
an interconnection agreement with Deutsche Telekom, currently the dominant
operator in Germany, to be able to offer long-distance services on a retail
and wholesale basis. No license is required for the provision of value-added
services such as the reorigination services that the Company currently
provides in Germany, or services to closed user groups using leased lines. A
change in regulatory policy or court decisions could result in the Company
either being required to invest further in the German market in order to
continue to receive the lowest available interconnection rates or having to
pay less favorable interconnection prices. Moreover, the Company is subject to
certain regulatory requirements when it operates under its license, including
the requirement that it present its standard terms and conditions to German
regulators and possibly that it contribute to universal service mechanisms.
There can be no assurance that the regulatory environment in Germany generally
or the applicable interconnection rates with Deutsche Telekom will allow the
Company to provide telecommunications services competitively with other
providers.
 
  Latin America. The recently completed TresCom Merger has provided the
Company with operations on several Caribbean islands and with customers in
several countries in Central America and South America. The Company may decide
to install switches and other network equipment in several of these countries.
Some 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 the Company to obtain numbers or
interconnection with the incumbent carrier. The Company initially will provide
to customers in several Latin American countries international call
reorigination or similar types of services that do not require the Company 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 the
Company will be able to obtain any authorizations or otherwise take the
actions necessary to provide services in these countries. See "Business--
Government Regulation."
 
  Other Jurisdictions. The Company intends to expand its operations into other
jurisdictions as such markets deregulate and it is able to offer a full range
of switched public telephone services to its 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 WTO 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 the Company's
entry into such additional markets. The ability of the Company to enter a
particular market and provide telecommunications services is dependent upon
 
                                      24
<PAGE>
 
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 the Company is able to gain entry to such a market,
no assurances can be given that it will be able to provide a full range of
services in such market, that it will not have to modify significantly its
operations to comply with changes in the regulatory environment in such
market, or that any such changes will not have a material adverse effect on
its business, results of operations or financial condition.
 
CONTROL OF PRIMUS
 
  The executive officers and directors of Primus beneficially own 9,542,041
shares of Primus Common Stock, representing 33.5% of the Common Stock. The
executive officers and directors have also been granted options to purchase an
additional 758,720 shares of Common Stock which vest after August 15, 1998. Of
these amounts, Mr. K. Paul Singh, Primus's Chairman and Chief Executive
Officer, beneficially owns 4,616,579 shares of Common Stock, including options
to purchase 225,400 shares of Common Stock. The Soros/Chatterjee Group (as
defined) beneficially owns 2,808,940 shares of Common Stock. Warburg, Pincus
(as defined) beneficially owns 3,875,689 shares of Common Stock. As a result,
the executive officers, directors, the Soros/Chatterjee Group and Warburg,
Pincus exercise significant influence over such matters as the election of the
Company's directors, amendments to the Company's charter, other fundamental
corporate transactions such as mergers, asset sales, and the sale of the
Company, and otherwise the direction of the Company's business and affairs.
Additionally, under the terms of a shareholders' agreement entered into in
connection with the TresCom Merger among Primus, Warburg, Pincus and Mr.
Singh, Primus has agreed to nominate one individual selected by Warburg,
Pincus and reasonably acceptable to the non-employee directors of Primus, 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 the outstanding Common Stock. In June 1998, Douglas Karp joined
the Primus board of directors pursuant to the foregoing arrangement. See
"Management--Executive Officers and Directors," "Security Ownership of Certain
Beneficial Owners and Management," and "Certain Transactions--Private Equity
Sale," "Recent Developments--TresCom Merger."
 
ABSENCE OF PUBLIC MARKET FOR THE NOTES
 
  The Exchange Notes are a new issue of securities, have no established
trading market, and may not be widely distributed. The Company does not intend
to list the Exchange Notes on any national securities exchange or to seek the
admission thereof to trading in The Nasdaq Stock Market. No assurance can be
given that an active public or other market will develop for the Exchange
Notes or as to the liquidity of or the trading market for the Exchange Notes.
If a trading market does not develop or is not maintained, holders of the
Exchange Notes may experience difficulty in reselling the Exchange Notes or
may be unable to sell them at all. If a market for the Exchange Notes
develops, any such market may be discontinued at any time. If a public trading
market develops for the Exchange Notes, future trading prices of the Exchange
Notes will depend on many factors, including, among other things, prevailing
interest rates, the Company's results of operations and the market for similar
securities, and the price at which the holders of Exchange Notes will be able
to sell such Exchange Notes is not assured and the Exchange 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 the financial condition of the Company, the Exchange Notes may trade
at a discount from their principal amount.
 
ABSENCE OF REGISTRATION UNDER STATE SECURITIES LAWS
 
  The Exchange 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 (within the meaning of Regulation S under the
Securities Act), as state securities laws do not apply to sales to persons who
are not residents of any state. In order to acquire the Initial Notes, each
Holder of Initial Notes was required to represent to the Company that it was
either (i) a "qualified institutional buyer" within the meaning of the Rule
144A under the Securities Act, (ii) an institutional "accredited investor"
within the meaning of subparagraph (a)(1), (2), (3) or (7) of Rule 501 under
the Securities
 
                                      25
<PAGE>
 
Act or (iii) a non-U.S. person within the meaning of Regulation S under the
Securities Act. Holders who wish to exchange their Initial Notes for Exchange
Notes pursuant to the Exchange Offer will be required to represent to the
Company that they remain institutional investors or non-U.S. persons, as they
represented at the time they acquired their Initial Notes. Any Holder who no
longer qualifies as such an institutional investor (e.g., a bank whose charter
has been revoked) or who is no longer a non-U.S. person, as the case may be,
will not be entitled to exchange such Initial Notes for Exchange 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 Initial
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 Initial Notes who do not exchange their Initial Notes for
Exchange 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 issuance of the Initial Notes 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 Initial 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. The
Company does not currently anticipate that it will register the Initial Notes
for resale under the Securities Act. Exchange Notes issued pursuant to the
Exchange Offer in exchange for Initial Notes may be offered for resale, resold
or otherwise transferred by holders thereof (other than any such holder which
is an "affiliate" of the Company within the meaning of Rule 405 under the
Securities Act and other than any broker-dealer who purchased Initial Notes
directly from the Company for resale pursuant to Rule 144A under the
Securities Act or any other available exemption under the Securities Act)
without compliance with the registration and prospectus delivery provisions of
the Securities Act provided that such Exchange 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 Notes. Each broker-
dealer that acquired Initial Notes for its own account as a result of market
making or other trading activities and that receives Exchange 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 Exchange Notes. The
Letter of Transmittal states that, by so acknowledging and by delivering a
prospectus, a broker-dealer will not be deemed to admit that it is an
"underwriter" within the meaning of the Securities Act. This Prospectus, as it
may be amended or supplemented from time to time, may be used by a broker-
dealer in connection with resales of Exchange Notes received in exchange for
Initial Notes where such Initial Notes were acquired by such broker-dealer as
a result of market-making activities or other trading activities. The Company
has agreed that, for a period of 180 days after the effective date of this
Prospectus, it will make this Prospectus, as it may be amended or supplemented
from time to time, available to any broker-dealer for use in connection with
any such resale. See "Plan of Distribution." However, to comply with the
securities laws of certain jurisdictions, if applicable, the Exchange 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 Initial Notes are
tendered and accepted in the Exchange Offer, the trading market for untendered
and tendered but unaccepted Initial Notes will be adversely affected.

                              THE EXCHANGE OFFER
 
PURPOSE AND EFFECT
 
  The Initial Notes were sold by the Company to the Initial Purchasers on May
19, 1998, pursuant to the Purchase Agreement. 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. The
Company and the Initial Purchasers also entered into the Registration Rights
Agreement, pursuant to which the Company agreed, with respect to the Initial
Notes, to (i) cause to be filed, on or prior to July 18, 1998, a registration
statement with the Commission under the Securities Act concerning the Exchange
Offer, (ii) use its reasonable best efforts to cause such registration
statement to be declared effective by the Commission on or prior to September
16, 1998 and (iii) to use its reasonable best efforts to cause the Exchange
Offer to remain open for a period of not less than 30 days. This Exchange
Offer is intended to satisfy the Company's exchange offer obligations under
the Registration Rights Agreement.
 
TERMS OF THE EXCHANGE OFFER
 
  The Company hereby offers, 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 Exchange Notes for each $1,000 in principal amount
of the outstanding Initial Notes. The Company 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 the Expiration Date. Tenders of the Initial Notes may be
withdrawn at any time prior to 5:00 p.m., New York City time, on the
Expiration Date. 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 conditions, terms and provisions of the
Registration Rights Agreement. The form and terms of the Exchange Notes will
be identical in all material respects to the form and terms of the Initial
Notes, except that (i) the Exchange 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 Exchange Notes
will not be entitled to Liquidated Damages, and (iii) holders of Exchange
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.
See "--Conditions of the Exchange Offer."
 
  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
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, $150.0 million in aggregate principal
amount of the Initial Notes is outstanding, the maximum amount authorized by
the Indenture for all Notes. As of    , 1998, CEDE was the sole registered
holder of the Initial Notes and held $150.0 million of aggregate principal
amount of the Initial Notes for   of its participants. Solely for reasons of
administration (and for no other purpose), the Company has fixed the close of
business on        , 1998, as the record date (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. The Company
believes that, as of the date of this Prospectus, no such the Holder is an
affiliate (as defined in Rule 405 under the Securities Act) of the Company.
 
  The Company shall be deemed to have accepted validly tendered Initial Notes
when, as and if the Company has 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 Exchange Notes from the
Company.
 
  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.
 
                                      27

EXPIRATION DATE; EXTENSIONS; AMENDMENTS
 
  The Expiration Date shall be        , 1998 at 5:00 p.m., New York City time,
unless the Company, in its sole discretion, extends 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, the Company 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.
 
  The Company reserves the right, in its 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 the Company to constitute
a material change, the Company will, in accordance with applicable law, file a
post-effective amendment to the registration statement (a "Post-effective
Amendment") and resolicit the registered holders of the Initial Notes. If the
Company files a Post-effective Amendment, it 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.
 
  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 the
Company (which may be contained in the Letter of Transmittal to the effect
that such Holder (i) is not an affiliate of the Company, (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 Exchange Notes to be
issued in the Exchange Offer and (iii) is acquiring the Exchange Notes in its
ordinary course of business. Each Holder using the Exchange Offer to
participate in a distribution of the Exchange Notes will be required to
acknowledge and agree that, if the resales are of Exchange Notes obtained by
such Holder in exchange for Initial Notes acquired directly from the Company
or an affiliate thereof, 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
 
                                      28
<PAGE>
 
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) the Company fails 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 Statement 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 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 such event referred to in clauses (i) through (iv) above, a
"Registration Default"), 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 the Company 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 Exchange Notes will bear interest at a rate equal to 9 7/8% 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 Exchange Notes,
such interest to be payable with the first interest payment on the Exchange
Notes. Interest on the Initial Notes accepted for exchange, which interest
accrued at the rate of 9 7/8% per annum, will cease to accrue on the day prior
to the issuance of the Exchange Notes. See "Description of Exchange Notes--
General."
 
PROCEDURES FOR TENDERING INITIAL NOTES
 
  The tender of a Holder's Initial Notes as set forth below and the acceptance
thereof by the Company will constitute a binding agreement between the
tendering Holder and the Company 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.
 
 
 
                                      29
<PAGE>
 
  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 defined). 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
(collectively, "Eligible Institutions"). 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 the Company in its 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.
 
  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 the Company in its sole discretion, which determination
shall be final and binding. The Company reserves the absolute right to reject
any and all Initial Notes not properly tendered and to reject any Initial
Notes the Company's acceptance of which might, in the judgment of the Company
or its counsel, be unlawful. The Company also reserves 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 the Company 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 the Company shall determine. The Company 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 the Company, proper evidence satisfactory to the Company, in
its sole discretion, of such person's authority to so act must be submitted.
 
  Any beneficial owner of the Initial Notes (a "Beneficial Owner") 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 the Company that,
among other things (i) the Exchange 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 Exchange 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 Exchange Notes
 
                                      30
<PAGE>
 
must comply with the registration and prospectus delivery requirements of the
Securities Act in connection with a secondary resale transaction of the
Exchange 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 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 Exchange 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 the Company except as otherwise disclosed to the Company in
writing. 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 ("Book-Entry Transfer
Facility") 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 defined 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 the Company 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, the
Company 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 Exchange 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, the Company shall be deemed to have accepted
validly tendered Initial Notes, when, as, and if the Company has given oral or
written notice thereof to the Exchange Agent.
 
  In all cases, issuances of Exchange 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
the Company reserves 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 (the
"Depositor"), (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 the Company in its 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 the Company, in its
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 the
Company. 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 the affairs of the Company 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, the Company may, at its discretion, take such action as it 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 the Company's consummation of the Exchange Offer
and compliance with the Registration Rights Agreement will be borne by the
Company, 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 Exchange 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
counsel for the Company, (v) fees and disbursements of independent certified
public accountants, (vi) rating agency fees, (vii) internal expenses of the
Company (including, without limitation, all salaries and expenses of officers
and employees of the Company performing legal or accounting duties), and (ix)
fees and expenses incurred in connection with the listing, if any, of the
Exchange Notes on a securities exchange.
 
  The Company has 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. The Company, however, will 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.
 
ACCOUNTING TREATMENT
 
  The Exchange Notes will be recorded at the same carrying value as the
Initial Notes, as reflected in the Company's accounting records on the date of
the exchange. Accordingly, no gain or loss will be recognized by the Company
for accounting purposes. The expenses of the Exchange Offer will be amortized
over the term of the Exchange 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, the Company believes that the Exchange
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 the Company 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 an affiliate of the Company 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 Exchange 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 Exchange Notes. The Company has not
requested or obtained an interpretive letter from the Commission staff with
respect to this Exchange Offer, and the Company 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 Exchange Notes in the Exchange Offer for the
purpose of distributing or participating in a distribution of the Exchange
Notes, such Holder cannot rely on the position of the staff of the Commission
enunciated in
 
                                      33
<PAGE>
 
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 Exchange 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 Exchange Notes. The Company has agreed that for a period of 180 days
after the effective date of this Prospectus, it will make this Prospectus, as
amended and supplemented, available to any broker-dealer who receives Exchange
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
Exchange 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. The
Company does not currently anticipate that it will register the Initial Notes
under the Securities Act. See "Risk Factors--Consequences of Failure to
Exchange."
 
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,
the Company 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 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. See "Description of Exchange
Notes." 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.
 
  The Company may in the future seek to acquire untendered Initial Notes in
open market or privately negotiated transactions, through subsequent exchange
offers or otherwise. The Company has no present plan to acquire any Initial
Notes which are not tendered in the Exchange Offer.

                              RECENT DEVELOPMENTS
 
TRESCOM MERGER
 
  On June 9, 1998, pursuant to the Merger Agreement, the Company acquired all
of the outstanding shares of TresCom, a facilities-based long distance
telecommunications carrier focused on international long distance traffic
originating in the United States and terminating in Latin America. The TresCom
Merger has provided Primus with accelerated entry into the Latin American
international long distance markets and expanded scope and coverage of the
Network, thereby providing additional opportunities to migrate traffic onto
the Network, resulting in better utilization of the Network and reduced
variable costs per minute of use. The Company believes that, in addition to
providing transmission facilities, and adding foreign carrier agreements and
direct connection to foreign telecommunications carriers, the TresCom Merger
adds experienced management, and will enable the combined Company to realize
synergies in selling, general and administrative expenses. Under the terms of
the Merger Agreement, TresCom shareholders received approximately 0.6147
shares of Common Stock for each share of TresCom common stock exchanged in the
TresCom Merger.
 
TELEPASSPORT/USFI ACQUISITION
 
  In October 1997, Primus completed the acquisition of all of the equity and
ownership interests of TelePassport and substantially all of the assets of
USFI for an aggregate purchase price of $11.5 million in cash. TelePassport
and USFI were under common control and engaged in the business of providing
international and domestic long distance and reorigination services in Europe,
Asia, and South Africa. The acquisition gave Primus a customer base in Germany
and a facilities-based carrier in Japan.
 
HOTKEY INVESTMENT
 
  In March 1998, Primus purchased a controlling interest in Hotkey, a
Melbourne, Australia based Internet service provider. The Company's 60%
ownership of Hotkey was purchased for approximately $1.3 million in cash and,
under certain circumstances, the Company has the right to acquire 100% of the
equity interest in Hotkey. Hotkey will allow Primus to offer Internet access
to its customers in Australia and will serve as the Company's entrance into
Internet protocol based telephony. Prior to the Hotkey investment, Primus's
chairman, K. Paul Singh, owned approximately 14% of Hotkey. As a result of the
transaction, Mr. Singh owns approximately 4% of Hotkey. See "Certain
Transactions."
 
ECLIPSE ACQUISITION
 
  In April 1998, Primus acquired all of the outstanding stock of Eclipse, a
data communications service provider based in Sydney, Australia. Eclipse
commenced operations in early 1996 and has approximately 100 business
customers, annualized revenues of approximately $4 million and data switches
and operational centers in all five capital cities in Australia. Primus paid
approximately $2.5 million for the stock of Eclipse, comprised of cash and
27,500 shares of Common Stock. With the acquisition of Eclipse, Primus now
offers a complete range of telecommunications services for corporate customers
in Australia, including fully integrated voice and data networks, as well as
Internet access services.

PRIMUS
  The following selected financial data should be read in conjunction with the
consolidated financial statements of Primus, and the notes thereto, contained
elsewhere in this Prospectus, and with "Management's Discussion and Analysis
of Financial Condition and Results of Operations." The statement of operations
data for Primus from inception to December 31, 1994, for the years ended
December 31, 1995, 1996, 1997, and the balance sheet data as of December 31,
1994, 1995, 1996 and 1997 have been derived from the consolidated financial

independent auditors. The statement of operations data for Primus for the
three months ended March 31, 1997 and 1998, and the balance sheet data as of
March 31, 1998, has been derived from the unaudited consolidated financial
statements of Primus, which, in management's opinion, include all adjustments
(consisting of only normal recurring adjustments) necessary for a fair
presentation of the information set forth therein.

(1) The ratio of earnings to fixed charges is computed by dividing pre-tax
    income from operations before fixed charges (other than capitalized
    interest) by fixed charges. Fixed charges consist of interest charges,
    whether expensed or capitalized, and that portion of rental expense the
    Company believes to be representative of interest. For 1994, 1995, 1996
    and 1997, and for the three months ended March 31, 1997 and 1998, earnings
    were insufficient to cover fixed charges by $0.6 million, $2.4 million,
    $8.6 million, $36.4 million, $5.1 million and $12.3 million, respectively.
(2) Consists primarily of net revenue from operations in the United States for
    all periods prior to April 1997. Net revenue for 1997 and for the three
    months ended March 31, 1998 reflects commencement of operations in Canada
    beginning in April, 1997.
(3) Consists solely of net revenue from operations in Australia for 1996. Net
    revenue for 1997 and for the three months ended March 31, 1998 reflects
    commencement of operations in Japan beginning in October 1997.
(4) Consists solely of net revenue from operations in the United Kingdom.
(5) As used herein, "EBITDA" is defined as net income or loss plus
    depreciation expense, amortization expense, interest expense and income
    taxes, minus extraordinary income and gains, if any, and plus
    extraordinary losses, if any. 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 herein to provide
    additional information regarding the ability of Primus to meet its future
    debt service, capital expenditures and working capital requirements.
    EBITDA is not necessarily a measure of Primus's ability to fund its cash
    needs and is not necessarily comparable to similarly titled measures of
    other companies.
(6) Capital expenditures include assets acquired, committed to be acquired and
    leased under capital lease agreements.

    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 herein to provide
    additional information regarding the ability of TresCom to contribute to
    the payment of the Company's future debt service, capital expenditures and
    working capital requirements. EBITDA is not necessarily a measure of the
    ability to fund cash needs and is not necessarily comparable to similarly
    titled measures of other companies.

                      UNAUDITED PRO FORMA FINANCIAL DATA
 
  The following unaudited pro forma consolidated financial statements are
based on the historical presentation of the consolidated financial statements
of the Company and TresCom. The Unaudited Pro Forma Consolidated Statement of
Operations for the three months ended March 31, 1998 gives effect to the
TresCom Merger and the Offering as if they had occurred on January 1, 1998.
The Unaudited Pro Forma Consolidated Statement of Operations for the year
ended December 31, 1997, gives effect to the TresCom Merger, the
TelePassport/USFI Acquisition and the Offering as if they had occurred on
January 1, 1997. The Unaudited Pro Forma Consolidated Balance Sheet as of
March 31, 1998 gives effect to the TresCom Merger and the Offering, as if they
had occurred on March 31, 1998. The unaudited pro forma consolidated financial
statements should be read in conjunction with the historical financial
statements, including notes thereto, of Primus, TresCom, and USFI, Inc.
included elsewhere herein.
 
  The TresCom Merger has been accounted for using the purchase method of
accounting. In the unaudited pro forma consolidated balance sheet the total
purchase price of TresCom has been allocated to tangible and intangible assets
and liabilities based upon management's preliminary estimate of their
respective fair values, with the excess of purchase price over the fair value
of net assets acquired allocated to goodwill.
 
  The unaudited pro forma consolidated financial statements may not be
indicative of the results that actually would have occurred if the
transactions had been in effect on the dates indicated or which may be
obtained in the future.

                     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
 
  Primus is a facilities-based global telecommunications company that offers
international and domestic long distance and other telecommunications services
to business, residential and carrier customers in North America and selected
markets within the Asia-Pacific region and Europe. Primus has recently
expanded its geographic presence in Latin America through its acquisition of
TresCom, which currently provides international long distance service
primarily for calls originating in the United States. The Company seeks to
capitalize on the increasing demand for high-quality international
telecommunications services resulting from the globalization of the world's
economies and the worldwide trend toward telecommunications deregulation.
Primus provides these services over its global intelligent network and through
resale arrangements and foreign carrier agreements. Currently the Company
serves approximately 275,000 customers in its Service Regions. The United
States, Australia and the United Kingdom are the most deregulated countries
within the Company's Service Regions and will serve as regional hubs for
Primus's intended expansion into additional markets as worldwide deregulation
of telecommunications markets continues.
 
  The Company was founded in February 1994, and through the first half of 1995
was a development stage enterprise involved in various start-up activities,
including raising capital, obtaining licenses, acquiring equipment, leasing
space, developing markets and recruiting and training personnel. The Company
began generating revenue during March 1995. On March 1, 1996 the Company
acquired Axicorp, the fourth largest telecommunications provider in Australia.
The acquisition of Axicorp has had a material effect on the Company's results
of operations for the year ended December 31, 1996. The Company's Australian
operations generated approximately $177.6 million, or 89%, of the Company's
pro forma net revenue for the year ended December 31, 1996.
 
  The Company has 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 switchless reseller of long distance, local and
cellular service. Since the acquisition, the Company has installed and begun
to carry traffic on a five-switch network in Australia, has 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. In addition, the Company has focused on
migrating existing traffic onto the Company's Network while increasing the
number of higher-margin, higher-volume business customers with significant
international long distance traffic. As part of its focus on business
customers, the Company has increased Axicorp's direct sales force and reduced
its reliance on marketing through trade and professional associations. The
Company has experienced and expects 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. The Company expects
to continue to upgrade Axicorp's facilities, increase its traffic capacity and
introduce new products and services. In that regard, the Company expanded its
service offerings in Australia with its acquisition in March 1998 of a
controlling interest in Hotkey, an Australia-based Internet service provider,
and its acquisition in April 1998 of all the outstanding stock of Eclipse, an
Australia-based data communications service provider.
 
  On June 9, 1998, pursuant to the Merger Agreement, the Company acquired the
operations of TresCom. After giving pro forma effect to the TresCom Merger and
the TelePassport/USFI Acquisition, for the year ended December 31, 1997, the
Company would have had net revenue of $448.9 million. After giving pro forma
effect to the TresCom Merger, for the three months ended March 31, 1998, the
Company would have had net revenue of $114.7 million. The TresCom Merger
provides Primus with accelerated entry into the Latin American international
long distance markets and expands the scope and coverage of the Network,
thereby providing
 
                                      45
<PAGE>
 
additional opportunities to migrate traffic onto the Network, resulting in
better utilization of the Network and reduced variable costs. The Company
believes that, in addition to providing transmission facilities, the TresCom
Merger adds foreign carrier agreements, direct connections to foreign
telecommunications carriers and experienced management, and enables the
combined Company to realize synergies in sales, marketing and administration.
See "Unaudited Pro Forma Financial Data."
 
  Net revenue is earned based on the number of minutes billable by the Company
and is recorded upon completion of a call, adjusted for sales allowance. The
Company generally prices its services at a savings compared to the major
carriers operating in the Service Regions. The Company's net revenue is
derived from carrying a mix of business, residential and wholesale carrier
long distance traffic and, in Australia, also from the provision of local and
cellular services. The Company expects to continue to generate net revenue
from internal growth through sales and marketing efforts focused, on a retail
basis, toward small- and medium-sized businesses with significant
international long distance traffic and ethnic residential customers and, on a
wholesale basis, to other telecommunications carriers and resellers with
international traffic in the Company's service areas.
 
  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, the Company believes that prices are likely to continue to decrease.
Additionally, the Company believes that because deregulatory influences only
recently have begun to affect non-United States and non-United Kingdom
telecommunications markets, the deregulatory trend in such markets is expected
to result in greater competition which could adversely affect net revenue per
minute and gross margin as a percentage of net revenue. The Company believes,
however, 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 the Company's cost of revenue is variable, based upon
the number of minutes of use, with transmission and termination costs being
the Company's most significant expense. As the Company increases the portion
of traffic transmitted over leased or owned facilities, cost of revenue
increasingly will be comprised of fixed costs. In order to manage such costs,
the Company pursues a flexible approach with respect to Network expansion. In
most instances, the Company initially obtains transmission capacity on a
variable-cost, per-minute leased basis, next acquires additional capacity on a
fixed-cost basis when traffic volume makes such a commitment cost-effective,
and ultimately purchases and operates its own facilities when traffic levels
justify such investment. The Company also seeks to lower its cost of revenue
through (i) optimizing the routing of calls over the least cost routing, (ii)
increasing volumes on its 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 foreign PTTs and others, and (iv) continuing to expand the Network when
traffic volumes justify such investment. See "Risk Factors--Managing Rapid
Growth" and "Business--Network."
 
  Typical of the long distance telecommunications industry, the Company
generally realizes a higher gross margin as a percentage of net revenue on its
international as compared to its domestic long distance services and expects
to realize a higher gross margin as a percentage of net revenue on its retail
(business and residential) services compared to those realized on its
wholesale services. In addition, the Company generally realizes a higher gross
margin as a percentage of net revenue on its long distance services as
compared to those realized on local switched and cellular services. Wholesale
services, which generate a lower gross margin as a percentage of net revenue
than retail services, are an important part of the Company's net revenue
because the additional traffic volume of such wholesale customers improves the
utilization of the Network and allows the Company to obtain greater volume
discounts from its suppliers than it otherwise would realize. The Company's
overall gross margin as a percentage of net revenue may fluctuate based on its
relative volumes of international versus domestic long distance services,
wholesale versus retail long distance services, and the proportion of traffic
carried on the Company's Network versus resale of other carriers' services.

  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 the Company's operations and the
transformation of Axicorp's operations. The Company expects this trend to
continue and believes that additional selling, general and administrative
expenses will be necessary to support the expansion of sales and marketing
efforts and operations in current markets as well as new markets in the
Service Regions.
 
  Since its inception, the Company has made, and expects to continue to make,
significant investments in the development of its operations in its Service
Regions and the development and expansion of the Network. The TresCom Merger
is expected to accelerate the timing, as well as the extent, of the expansion
of the Network. The costs of developing its operations and expanding the
Network, including the purchase and installation of switches, sales and
marketing expenses and other organizational costs, are significant. In
addition, increased capital investment activity in the future can be expected
to affect the Company's operating results in the near term due to increased
depreciation charges and interest expense in connection with borrowings to
fund such expenditures, which costs will be incurred in advance of the
realization of the expected improvements in operating results from such
investments. Such costs and investment activity have resulted in negative cash
flows and operating losses for the Company on an historical basis, which are
expected to continue to increase in the near future as the Company uses the
proceeds of the Offering to accelerate the expansion of its business and the
build-out of the Network. See "Use of Proceeds" and "--Liquidity and Capital
Resources."
 
  Although the Company's functional currency is the United States dollar, the
majority 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 the majority of its net revenue and incur a significant portion of its
operating costs outside the United States and changes in exchange rates may
have a significant effect on the Company's results of operations. The Company
historically has not engaged in hedging transactions, and does not currently
contemplate engaging in hedging transactions to mitigate foreign exchange
risk. See "Risk Factors--Risk Associated with International Operations."

RESULTS OF OPERATIONS
 
 For the three months ended March 31, 1998 as compared to the three months
ended March 31, 1997
 
  Net revenue increased $21.1 million or 36%, from $59.0 million for the three
months ended March 31, 1997 to $80.1 million for the three months ended March
31, 1998. Of the increase, $18 million was associated with the North American
operations, which represents a growth rate of approximately 218%
(approximately 167% exclusive of net revenue associated with the
Telepassport/USFI operations acquired in the fourth quarter of 1997), as a
result of increased traffic volumes primarily in its wholesale carrier
operations and, to a lesser extent, in its business and residential customer
base. The European operations contributed $5.2 million to the period-over-
period net revenue growth, which represents a growth rate of approximately
134%. The European net revenue increased from $3.9 million for the three
months ended March 31, 1997 to $9.1 million for the three months ended March
31, 1998, resulting primarily from wholesale traffic being carried in 1998,
and to a lesser extent, growth in retail customer traffic. The Company's Asia-
Pacific net revenue decreased by $2.2 million or 5%, from $46.9 million for
the three months ended March 31, 1997 to $44.7 million for the three months
ended March 31, 1998. The decrease in the Asia-Pacific net revenue was
primarily a result of a 14% drop in the Australian dollar's average exchange
rate and, to a lesser extent, a change in traffic mix away from lower-margin
local traffic in favor of higher-margin long distance traffic.
 
  Cost of revenue increased $13.7 million, from $55.0 million, or 93% of net
revenue, for the three months ended March 31, 1997 to $68.7 million, or 86% of
net revenue, for the three months ended March 31, 1998. The increase in the
cost of revenue is attributable to the increase in traffic volumes. The
decrease in the cost of revenue as a percentage of net revenue is reflective
of the expansion of the Company's global network, the continuing migration of
existing and newly generated customer traffic onto the Company's network,
especially in Australia with the advent of equal access, and a change in the
Australian traffic mix away from lower-margin local traffic.
 
  Gross margin increased $7.3 million, from $4.0 million, or 6.8% of net
revenue, for the three months ended March 31, 1997 to $11.3 million, or 14.2%
of net revenue, for the three months ended March 31, 1998. The approximately
740 basis point increase in the gross margin as a percentage of net revenue is
due to the reduction in cost of revenue factors stated above.
 
  Selling, general and administrative expenses increased $6.6 million, from
$8.8 million to $15.4 million for the three months ended March 31, 1997 and
1998, respectively. The increase is attributable to the hiring of additional
sales and marketing staff and engineering personnel, the addition of expenses
from acquired operations, and increased advertising and promotional expenses
associated primarily with the Company's residential marketing campaigns in
Australia.
 
  Depreciation and amortization expense increased from $0.8 million for the
three months ended March 31, 1997 to $3.5 million for the three months ended
March 31, 1998. The increase is associated with increased depreciation expense
from capital expenditures for fiber, switching and other network equipment
being placed into service and increased amortization expense associated with
intangible assets acquired in the Company's acquisitions.
 
  Interest expense increased from $0.2 million for the three months ended
March 31, 1997 to $7.2 million for the three months ended March 31, 1998. The
increase is primarily attributable to the interest expense associated with the
Company's 1997 Senior Notes and Warrants Offering.
 
  Interest income of $2.4 million for the three months ended March 31, 1998 is
attributable to the investment of the Company's cash, cash equivalents and
restricted investment balances.
 
 
                                      48
<PAGE>
 
 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 the Company's 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 the Company's 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%, 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 the
investments made by the Company in its Network and the associated migration of
customer traffic onto the 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 the Company's 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 the Company's Network; the TelePassport/USFI Acquisition
and operations acquired in Canada during 1997; a full year of the Company's
Australian operations versus ten months in the prior year; and increased
advertising and promotional expenses associated with the Company's 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 the Company's 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 the
Company's 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 the Company's 1997 Senior
Notes offering and its 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
 
                                      49

transaction gains/losses on Australian dollar-denominated debt incurred by the
Company for its 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 the Company's United
Kingdom and Australian subsidiaries.
 
 For the year ended December 31, 1996 as compared to the year ended December
31, 1995
 
  Net revenue increased $171.8 million, from $1.2 million for the year ended
December 31, 1995 to $173.0 million for the year ended December 31, 1996. Of
the increase, $151.3 million was associated with the Company's Australian
operations, which were acquired March 1, 1996, while the remaining $20.5
million of net revenue growth was associated primarily with the commencement
and expansion of the Company's operations in the United States and the United
Kingdom.
 
  Cost of revenue increased $157.4 million, from $1.4 million for the year
ended December 31, 1995 to $158.8 million for the year ended December 31, 1996
as a direct result of the increase in traffic volume. Most of the Company's
costs of revenue are variable, since the Company had a limited Network during
this period and functioned primarily as a switchless reseller. The cost of
revenue in the United States reflects the start-up nature of the network
operations and traffic being carried on more expensive carriers until adequate
capacity on lower cost carriers could be established.
 
  Selling, general and administrative expenses increased $18.1 million, from
$2.0 million to $20.1 million for the year ended December 31, 1996 as compared
to the year ended December 31, 1995. Approximately $11.4 million of the
increase was attributable to the ten months of activity associated with the
Australian operations, and the remaining $6.7 million related to the non-
Australian operations was a result of increased staffing levels, increased
sales and marketing activity and network operations costs. The non-Australian
selling, general and administrative costs as a percentage of non-Australian
net revenue for the year ended December 31, 1996 was 40%, which is reflective
of the growth in the infrastructure necessary to support future non-Australian
net revenues. The Australian selling, general and administrative expense as a
percentage of Australian net revenue was 7.5% for the 10 months ended December
31, 1996.
 
  Depreciation and amortization increased from $0.2 million for the year ended
December 31, 1995 to $2.2 million for the year ended December 31, 1996. The
majority of the increase is a result of the acquisition of Axicorp and is
comprised of amortization of goodwill and the customer list which totaled $1.3
million. The remaining depreciation is related primarily to Axicorp's assets
and increased depreciation expense for the Company as a result of additional
capital expenditures for switching and network related equipment.
 
  Other income (expense) for the year ended December 31, 1996 related to
foreign currency transaction losses on the Australian dollar-denominated debt
incurred by the Company payable to the sellers for its acquisition of Axicorp
as a result of the appreciation of the Australian dollar against the U.S.
dollar during the period.
 
  Income taxes were primarily attributable to the operations of Axicorp for
the 10 months from the date of purchase, and represent the amount of expense
for Australian taxes.
 
 Pro Forma Results of Operations for the Year Ended December 31, 1996 Compared
to the Year Ended December 31, 1995
 
  As a result of the Company's acquisition of Axicorp on March 1, 1996 and the
development stage nature of the Company in the first quarter of 1995, the
Company believes that a discussion of the pro forma results of operations for
the 12 months ended December 31, 1995 and 1996, which results give effect to
the acquisition of Axicorp as if it had occurred on January 1, 1995, is
helpful to an understanding of the Company's results of operations.

  Net revenue increased $73.7 million or 59%, from $125.6 million for the year
ended December 31, 1995 to $199.3 million for the year ended December 31,
1996. The Australian net revenue increased 43%, or $53.1 million, from $124.5
million to $177.6 million. The increase was attributable to an increase in
minutes of traffic from small- to medium-sized business customers, as well as
growth in the number of customers. Non-Australian net revenue was $21.7
million for the year ended December 31, 1996 as compared to net revenue of
$1.2 million for the year ended December 31, 1995. The $20.5 million increase
is the result of an increase of $15.4 million in the United States, primarily
associated with increased wholesale traffic volume and, to a lesser extent,
from consumer customers resulting from the ethnic marketing program and
business customers resulting from the Company's build-up of its direct sales
force, and an increase of $5.1 million in the United Kingdom associated with
the commencement of operations in late 1995.
 
  Cost of revenue increased $68.0 million or 59%, from $114.6 million for the
year ended December 31, 1995 to $182.6 million for the year ended December 31,
1996. The increase was the direct result of increased traffic volumes the
Company carried for its customers. The Australian cost of revenue increased
43%, or $48.1 million, from $113.3 million for the year ended December 31,
1995 to $161.4 million for the year ended December 31, 1996. The Australian
cost of revenue increase is primarily driven by an increased number of
business customers and associated traffic volumes. The Australian cost of
revenue as a percentage of Australian revenue was essentially flat and
reflects the continued resale of carrier services and lack of network
facilities. The non-Australian cost of revenue increased $19.8 million from
$1.4 million for the year ended December 31, 1995 to $21.2 million for the
year ended December 31, 1996, as a result of increased traffic volumes for
business, consumer, and wholesale customers in the United States and the
commencement of operations in the United Kingdom. Non-Australian cost of
revenue as a percentage of non-Australian net revenue was 97.6% in the year
ended December 31, 1996 versus 118.6% in the year ended December 31, 1995. The
non-Australian cost of revenue as a percentage of non-Australian net revenue
reflects the start up nature of network operations in the United States and
the United Kingdom, the absence of network facilities, traffic being carried
on more expensive carriers until adequate capacity on lower cost carriers
could be established, and lack of return traffic on newly initiated foreign
carrier agreements.

  Gross margin increased $5.7 million or 52%, from $11.0 million for the year
ended December 31, 1995 to $16.7 million for the year ended December 31, 1996.
The Australian gross margin as a percentage of Australian net revenue remained
constant for the years ended December 31, 1995 and 1996. The non-Australian
gross margin increased from a deficit of $(0.2) million for the year ended
December 31, 1995 to a gross margin of $0.5 million for the year ended
December 31, 1996.
 
  Selling, general and administrative expenses increased $9.2 million or 71%,
from $13.0 million for the year ended December 31, 1995 to $22.2 million for
the year ended December 31, 1996. The Australian operations increased selling,
general and administrative expenses by $2.5 million as a result of increased
salaries and benefits for additional sales and operations staff to support
construction of a new five city switched network. The Australian selling,
general and administrative expenses as a percentage of Australian net revenue
decreased from 9% to 8% for the years ended December 31, 1995 and 1996,
respectively. The non-Australian operations account for the remaining increase
of $6.7 million which is due to increased staffing in sales and marketing,
network operations, and customer service. The non-Australian selling, general
and administrative expenses as a percentage of non-Australian net revenue
decreased to 40% for the year ended December 31, 1996, from 173% for the year
ended December 31, 1995, as a result of these costs being spread over an
increasing revenue base.
 
  Depreciation and amortization increased $0.7 million or 34%, from $1.8
million for the year ended December 31, 1995 to $2.5 million for the year
ended December 31, 1996. The increase reflects depreciation for capital
expenditures for network equipment associated with the Company's network
construction.
 
  Interest expense increased 12% as a result of additional capital leases to
finance network switching equipment.
 
  Interest income increased from $0.1 million for the year ended December 31,
1995 to $0.9 million for the year ended December 31, 1996 as a result of the
interest earned on the cash balance generated from the private placements in
February 1996 and July 1996, and the initial public offering in November 1996.
 
  Other income (expense) is comprised of foreign currency transaction loss of
$0.3 million for the year ended December 31, 1996 associated with the debt
related to the acquisition of Axicorp, which is denominated in Australian
dollars. Fluctuations in the currency exchange rates between the Australian
and United States dollar will cause currency transaction gains or losses which
are recognized in the current period results of operations.
 
  Income taxes are based on the income before taxes generated primarily by the
operations in Australia.
 
LIQUIDITY AND CAPITAL RESOURCES
 
  The Company's liquidity requirements arise from net cash used in operating
activities; purchases of network equipment including switches, related
transmission equipment, and international and domestic fiber cable capacity;
interest and principal payments on outstanding indebtedness; and acquisitions
of and strategic investments in businesses. The Company has financed its
growth to date through the August 1997 offering of the 1997 Senior Notes, the
November 1996 initial public offering of Common Stock, several private
placements of Common Stock, and capital lease financing. The semi-annual
interest payments due under the 1997 Senior Notes through August 1, 2000 have
been pre-funded and will be paid from restricted investments.
 
  Net cash used in operating activities was $17.1 million for the three months
ended March 31, 1998, and net cash provided by operating activities was $1.8
million for the three months ended March 31, 1997. Net cash used in operating
activities was $14.8 million for the year ended December 31, 1997, $6.9
million for the year ended December 31, 1996, and $2.0 million for the year
ended December 31, 1995. The increase in cash used in operating activities for
the three month period ended March 31, 1998 is primarily comprised of $7.4
million for an increase in the net loss and a $6.3 million increase in accrued
interest payable related to the 1997 Senior Notes. 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.
 
                                      52
<PAGE>
 
The increased cash usage for the years ended December 31, 1996 and 1995 was
the result of an increase in the net loss partially offset by increases in
accounts payable and accrued expenses.
 
  Net cash used in investing activities was $0.9 million for the three months
ended March 31 1998 and net cash provided by investing activities was $11.0
million for the three months ended March 31, 1997. Net cash used in investing
activities was $104.2 million for the year ended December 31, 1997, $39.6
million for the year ended December 31, 1996 and $0.4 million for the year
ended December 31, 1995. Net cash used in investing activities during the
three months ended March 31, 1998 includes $11.4 million of capital
expenditures primarily for the expansion of the Company's global network, and
$1.6 million for business acquisitions and investments, partially offset by
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 the Network, the TelePassport/USFI
Acquisition and the acquisition of the Company's 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 the Network and $1.7 million for
the purchase of Axicorp, net of cash acquired.
 
  Net cash provided by financing activities was $0.1 million for the three
months ended March 31, 1998 and net cash used by financing activities of $4.4
million during the three months ended March 31, 1997. Net cash provided by
financing activities was $200.1 million for the year ended December 31, 1997,
$79.5 million for the year ended December 31, 1996 and $4.5 million for the
year ended December 31, 1995. Cash provided by financing activities in the
three months ended March 31, 1998 resulted from the issuance of the Company's
Common Stock through the exercise of employee options. Net cash provided by
financing activities for the year ended December 31, 1997 resulted primarily
from the proceeds of the offering of 1997 Senior Notes less deferred financing
costs. In 1996, the Company completed private placements of Common Stock
generating net proceeds of approximately $21.9 million, and in November 1996,
the Company completed an initial public offering of its Common Stock and
generated net proceeds of approximately $54.4 million.
 
  The Company anticipates aggregate capital expenditures of approximately $225
million during 1998 and 1999 (of which approximately $11.4 million was
expended in the three months ended March 31, 1998). Such capital expenditures
will be primarily for international and domestic switches and Pops,
international and domestic fiber optic cable capacity and satellite earth
station facilities for new and existing routes, and other transmission
equipment and support systems. The Company is currently installing an
additional international gateway switch in Frankfurt, Germany and, by the end
of 1999, intends to add up to three switches in North America, two switches in
Europe, one switch in the Asia-Pacific region, and three switches in Latin
America.
 
  The Company believes that the net proceeds from the Offering, together with
its existing cash and available capital lease financing (subject to
limitations in the Indenture) will be sufficient to fund the Company's
operating losses, debt service requirements, capital expenditures and other
cash needs for its operations for at least the next 18 to 24 months. The
Company is continually evaluating the expansion of the Network and plans to
accelerate its investment in international and domestic fiber optic cable
capacity and other transmission facilities. In addition, the Company expects
to make additional investments in the TresCom network in order to expand
services in Latin America. In order to fund these additional cash
requirements, including the expansion of the combined Network, Primus
anticipates that it will be required to raise a significant amount of cash in
excess of its existing cash and cash equivalents. Consequently, the Company
expects to raise additional capital from public or private equity or debt
sources to meet its new financing needs, including for the continued buildout
of the Network. Additionally, if the Company's plans or assumptions change
(including those with respect to the development of the Network, the level of
its operations and its operating cash flow), if its assumptions prove
inaccurate, if it consummates additional investments or acquisitions or if it
experiences unexpected costs or competitive pressures, or if existing cash and
any other borrowings prove to be insufficient, the Company may be required to
seek additional capital sooner than expected. See "Risk Factors--Need for
Additional Financing."

  Since inception through March 31, 1998, the Company had negative cash flow
from operating activities of $41.3 million and negative EBITDA of $35.9
million. In addition, the Company incurred net losses in 1995, 1996, 1997 and
the three months ended March 31, 1998, of $2.4 million, $8.8 million, $36.2
million and $12.3 million, respectively, and had an accumulated deficit of
approximately $60.3 million as of March 31, 1998. On a pro forma basis, after
giving effect to the Offering, TelePassport/USFI Acquisition and the TresCom
Merger, for the year ended December 31, 1997, the Company would have had a net
loss of $76.5 million. On a pro forma basis, after giving effect to the
Offering and the TresCom Merger, for the three months ended March 31, 1998,
the Company would have had a net loss of $21.7 million. Although the Company
has experienced net revenue growth in each of its last 13 quarters, such
growth should not be considered to be indicative of future net revenue growth,
if any. The Company expects to continue to incur additional operating losses,
negative EBITDA and negative cash flow from operations as it expands its
operations and continues to build-out and upgrade the Network. There can be no
assurance that the Company's revenue will grow or be sustained in future
periods or that it will be able to achieve or sustain profitability or
positive cash flow from operations in any future period. If the Company cannot
achieve and sustain operating profitability or positive cash flow from
operations, it may not be able to meet its debt service or working capital
requirements (including its obligations with respect to the Notes).
 
  From time to time the Company evaluates acquisitions of businesses which
complement the business of the Company. Depending on the cash requirements of
potential transactions, the Company may finance such transactions with bank
borrowings, through other debt financing vehicles, or through the issuance of
capital stock. The Company, however, presently has no understanding,
commitment or agreement with respect to any acquisition. There can be no
assurance that if the Company were to pursue such an opportunity, any such
acquisition would occur or that the funds to finance any such acquisition
would be available on reasonable terms, if at all.
 
  Year 2000 Compliance. In accordance with Securities and Exchange Commission
Staff Legal Bulletin No. 5, dated October 8, 1997, the Company has begun a
review and assessment of the anticipated costs, problems and uncertainties
associated with Year 2000 issues. The Company is implementing a Year 2000
compliance plan whereby each operating unit is responsible for identifying
systems requiring modification or conversion (both internal systems and those
provided by or otherwise available from outside vendors) and periodically
reporting its progress in meeting milestones toward compliance. The Company
believes that Year 2000 issues will not materially affect its products,
services, or competitive conditions and that its costs of addressing Year 2000
compliance will not materially impact future operating results or financial
condition. See "Risk Factors--Dependence on Effective Information Systems;
Year 2000 Problem."
 
TRESCOM
 
  Summary. TresCom is a facilities-based long distance telecommunications
carrier focused on international long distance traffic originating in the
United States. TresCom offers a broad array of competitively priced services,
including long distance, calling cards, prepaid debit cards, domestic and
international toll-free calling, frame relay and bilingual operator services.
TresCom derives its revenues by providing international and domestic long
distance services on a wholesale basis to other telecommunications carriers
and resellers and on a retail basis to residential and commercial customers,
ranging in size from small businesses to Fortune 500 companies. Service
revenues are based on minutes of use and charged at a rate per minute which
varies according to the termination point of the traffic and time of day. All
revenues are billed in United States dollars.
 
  Since its formation, TresCom has expanded its revenues, customer base and
network through internal growth and acquisitions. TresCom seeks to continue to
expand its revenues from internal growth through four distinct sales channels:
(i) direct sales efforts; (ii) an agent sales network; (iii) ethnic focused
telemarketing programs; and (iv) wholesale sales activities. TresCom believes
that it has established the network, operations, customer service,
infrastructure and systems necessary to support its expanding sales and
customer base for the foreseeable future. A substantial portion of TresCom's
revenues are derived from wholesale sales. Increased worldwide competition has
continued to drive down wholesale prices.
 
                                      54
<PAGE>
 
  Cost of services includes those costs associated with the transmission and
termination of services over TresCom's international network. Transmission and
termination costs are TresCom's most significant expense, and TresCom seeks to
lower these costs through: (i) increasing volume on its owned facilities,
thereby spreading the allocation of fixed costs over a larger number of
minutes; (ii) negotiating lower cost direct operating and transit agreements
with PTTs and foreign telecommunications administrations ("TAs"); and (iii)
optimizing the routing of calls over the least cost route on its international
network. Consistent with its strategy of maximizing traffic carried on
TresCom's own network, TresCom significantly expanded the network switch
capacity in 1997.
 
  The majority of TresCom's cost of services is variable and consists of
payments for leased capacity from other carriers and payments to PTTs and TAs
with which TresCom has direct operating and transit agreements. Under its
direct operating agreements, TresCom agrees to send United States originated
traffic to the PTTs or TAs and the PTTs or TAs agree to send a proportionate
amount of return traffic at agreed upon accounting rates. If there is an
imbalance in the volume of traffic sent and received in return, the carrier
that originates more traffic pays for the difference to compensate the other
carrier. The difference is the settlement payment. Under TresCom's direct
operating agreements, TresCom's net settlement revenues and payments are
denominated in United States dollars.
 
  TresCom's profitability is driven by the difference between net revenues and
the cost of leased capacity and settlement payments to PTTs and TAs. In order
to minimize the costs of leased capacity and settlement payments, TresCom
utilizes a Least Cost Routing System designed to transmit TresCom's traffic
over the least cost route choice on the network. Based on FCC data for the
period from 1989 through 1996, per minute settlement payments from United
States carriers to PTTs and TAs have declined at a significantly faster rate
than per minute billed revenues. Due to the WTO Agreement, TresCom expects
this trend to continue.
 
 For the three months ended March 31, 1998 compared to the three months ended
March 31, 1997
 
  Revenues. Revenues increased 5.5%, or $2.0 million, from $36.1 million in
the first quarter of 1997, to $38.1 million in the first quarter of 1998.
Minutes of use increased 11.5%, or 13.4 million minutes, from 116.8 million in
the first quarter of 1997, to 130.2 million in the first quarter of 1998.
International traffic accounted for approximately 79% of total revenue in the
first quarter of 1997, and approximately 77% of total revenue in the first
quarter of 1998. This, combined with continued international wholesale price
pressures and changes within the mix of international terminations, caused the
overall rate per minute to decline from approximately $0.31 in the first
quarter of 1997, to $0.29 in the first quarter of 1998. Historically,
international traffic has commanded a higher per minute rate than domestic
traffic; however, this gap has been decreasing due to increased international
competition and declining international termination costs.
 
  Costs of Services. Costs of services increased 11.5%, or $3.2 million, from
$27.8 million in the first quarter of 1997, to $31.0 million in the first
quarter of 1998. Costs of services increased instep with the increased volume
of traffic carried. On a per minute basis, however, the variable portion of
the cost per minute decreased from approximately $0.23 in the first quarter of
1997, to approximately $0.21 in the first quarter of 1998. This decline was
offset by TresCom's investment in the expansion of its network, represented by
higher fixed per minute costs of services.
 
  Gross Profit. Gross profit decreased 13.3%, or $1.1 million, from $8.3
million in the first quarter of 1997, to $7.2 million in the first quarter of
1998. As a percentage of revenues, gross profit decreased from approximately
23% in the first quarter of 1997 to approximately 19% in the first quarter of
1998.
 
  Selling, General and Administrative Expense. Selling, general and
administrative expense increased 14.8%, or $1.2 million, from $8.1 million in
the first quarter of 1997, to $9.3 million in the first quarter of 1998. This
increase was due primarily to increased expenses, such as additional reserves
for bad debt. Bad debt expense was $1.0 million and $1.8 million in the first
quarter of 1997 and 1998, respectively.
 
  Depreciation and Amortization. Depreciation and amortization expense
increased 26.7%, or $0.4 million, from $1.5 million in the first quarter of
1997, to $1.9 million in the first quarter of 1998. This increased expense
 
                                      55
<PAGE>
 
is due to the depreciation of assets acquired to support continued expansion
of TresCom's network and amortization related to acquired businesses and
customer bases.
 
  Interest Expense, Net. Interest expense, net, increased to $0.4 million in
the first quarter of 1998 due to interest associated with TresCom's capital
leases and borrowings under the revolving credit agreement.
 
  Net Loss. Net loss increased 71.1%, or $3.2 million, from $1.3 million in
the first quarter of 1997, to $4.5 million in the first quarter of 1998, due
to the above factors.
 
 For the year ended December 31, 1997 compared to year ended December 31, 1996
 
  Revenues. Revenues increased 12.9%, or $18.0 million, from $139.6 million in
1996 to $157.6 million in 1997 due to an increase in the volume of traffic
carried, offset, in part, by a decrease in average revenue per minute. Minutes
of use increased 18.1%, or 82.4 million, from 455.5 million in 1996 to 537.9
million in 1997. Although international traffic accounted for approximately
80.0% of TresCom's revenue in both 1997 and 1996, the overall revenue per
minute decreased to approximately $0.29 in 1997 from approximately $0.31 in
1996 as a result of continued international wholesale price pressures and a
change in the mix of international terminations.
 
  Costs of Services. Costs of services increased 16.4%, or $17.5 million, from
$106.9 million in 1996 to $124.4 million in 1997. The increased costs are a
factor of increased minutes of use, the costs of which are variable in nature,
partially offset by a fractional decrease in the overall cost per minute
resulting from changes in the mix of international terminations and lower
termination costs derived from certain direct operating agreements.
 
  Gross Profit. Gross profit increased 1.8%, or $0.6 million, from $32.7
million in 1996 to $33.3 million in 1997. As a percentage of revenues, gross
profit decreased from 23.4% in 1996 to 21.1% in 1997 reflecting the impact of
the international wholesale price pressures referred to above.
 
  Selling, General and Administrative Expense. Selling, general and
administrative expense increased 18.2%, or $5.6 million, from $30.8 million in
1996 to $36.4 million in 1997. After giving effect to a one-time $1.5 million
promotional credit for services rendered by a vendor in 1996, selling, general
and administrative expense, as a percentage of revenues, was approximately
23.1% for both 1997 and 1996. On an absolute basis, the increase was primarily
due to variable costs associated with growth in the retail business, such as
advertising, commissions and billing costs.
 
  Depreciation and Amortization. Depreciation and amortization expense
increased 34.7%, or $1.7 million, from $4.9 million in 1996 to $6.6 million in
1997. The increased expense is due to depreciation of assets acquired to
support continued expansion of TresCom's network and amortization related to
acquired businesses and customer bases.
 
  Interest and other expenses, net. Interest and other expenses, net,
increased 83.3%, or $0.5 million, from $0.6 million in 1996 to $1.1 million in
1997. The increase is primarily due to additional borrowings under TresCom's
revolving credit agreement.
 
  Extraordinary Item. Extraordinary expense decreased 100%, or $2.0 million,
from 1996 to 1997. The extraordinary expense in 1996 of $2.0 million was a
result of the early extinguishment of $35.8 million of indebtedness in
February of such year. Approximately $1.5 million was attributable to debt and
warrants payable to a major shareholder of TresCom and approximately $0.5
million was related to the write-off of deferred financing costs associated
with TresCom's bank facility.
 
  Net Loss. Net loss increased 94.6%, or $5.3 million, from $5.6 million in
1996 to $10.9 million in 1997 due to the above factors.
 
 
                                      56
<PAGE>
 
 For the year ended December 31, 1996 compared to year ended December 31, 1995
 
  Revenues. Revenues increased 36.1%, or $37.0 million, from $102.6 million in
1995 to $139.6 million in 1996 due to a 37.9% increase in minutes of use from
330.3 million in 1995 to 455.5 million in 1996, offset in part by a fractional
decrease in average revenue per minute resulting from pricing pressures and a
change in the mix of international terminations. In 1996, approximately 80.0%
of TresCom's revenue was derived from international traffic compared with
approximately 75.0% in 1995. Historically, international traffic has commanded
a higher per minute rate than domestic traffic, however this gap is decreasing
due to increased international competition.
 
  Costs of Services. Costs of services increased 43.1%, or $32.2 million, from
$74.7 million in 1995 to $106.9 million in 1996. This increase resulted from a
greater percentage of international traffic in 1996 (approximately 80.0%)
compared to 1995 (approximately 75.0%) as discussed above. The cost per minute
also increased in absolute terms due to higher cost countries within the
international mix.
 
  Gross Profit. Gross profit increased 16.8%, or $4.7 million, from $28.0
million in 1995 to $32.7 million in 1996. As a percentage of revenues, gross
profit decreased from 27.3% in 1995 to 23.4% in 1996. The primary factors
contributing to the increase in gross profit are TresCom's mix of business and
continued international competitive pressures as described above.
 
  Selling, General and Administrative Expense. Selling, general and
administrative expense decreased 4.9%, or $1.6 million, from $32.4 million in
1995 to $30.8 million in 1996. The 1995 selling, general and administrative
expense reflects a $4.1 million charge for a settlement with a major customer,
and a $1.7 million charge for expenses relating to Hurricane Marilyn (which
hit St. Thomas, a significant base of operations for TresCom, in September
1995). The 1996 expense reflects a $1.5 million promotional credit for
services rendered by a vendor and $0.6 million associated with a one-time cash
compensation charge relating to changes in executive management during the
year. After giving effect to these items, selling, general and administrative
expense, as a percentage of revenues, decreased from 26.0% in 1995 to 22.7% in
1996.
 
  Depreciation and Amortization. Depreciation and amortization expense
increased 22.5%, or $0.9 million, from $4.0 million in 1995 to $4.9 million in
1996. The increased expense is due to depreciation of assets acquired during
1996 to support continued expansion of TresCom's network and corporate
infrastructure.
 
  Interest and other expenses, net. Interest and other expense, net, decreased
81.3%, or $2.6 million, from $3.2 million in 1995 to $0.6 million in 1996. The
decrease is primarily due to the repayment of borrowings under a bank facility
between TresCom Network Services, Inc., a wholly-owned subsidiary of TresCom,
and a commercial bank and due to the repayment of borrowings from a major
shareholder, each in February 1996.
 
  Extraordinary Item. The extraordinary expense in 1996 of $2.0 million was a
result of the early extinguishment of $35.8 million of indebtedness in
February. Approximately $1.5 million was attributable to debt and warrants
payable to a major shareholder of TresCom and approximately $0.5 million was
related to the write-off of deferred financing costs associated with the Bank
Facility.
 
  Net Loss. Net loss decreased 51.7%, or $6.0 million, from $11.6 million in
1995 to $5.6 million in 1996 due to the above factors.
 
 Year 2000
 
  TresCom has determined that it will need to modify or replace significant
portions of its software so that its computer systems will function properly
with respect to dates in the year 2000 and beyond. The majority of the
software which needs to be replaced by TresCom is under license from third-
party software manufacturers who have indicated that they will provide the
necessary upgrades. TresCom also has initiated discussions with its
significant suppliers, large customers and financial institutions to ensure
that those parties have appropriate plans to remediate Year 2000 issues where
their systems interface with TresCom's systems or otherwise impact its
 
                                      57
<PAGE>
 
operations. TresCom is assessing the extent to which its operations are
vulnerable should the organizations fail to remediate properly their computer
systems.
 
  TresCom's comprehensive Year 2000 initiative is being managed by a team of
internal staff and outside consultants. The team's activities are designed to
ensure that there is no adverse effect on TresCom's core business operations
and that transactions with suppliers, customers and financial institutions are
fully supported. TresCom is well under way with these efforts, which are
scheduled to be completed in early 1999. While TresCom believes its planning
efforts are adequate to address its Year 2000 concerns, there can be no
assurance that the systems of other companies on which TresCom's systems and
operations rely will be converted on a timely basis and that such conversion
will not have a material effect on TresCom. The cost of the Year 2000
initiatives is not expected to be material to TresCom's results of operations
or financial position.
 
 Liquidity and Capital Resources
 
  A separate liquidity and capital resources section has not been presented
for TresCom on a stand-alone basis as it would not be meaningful to an
understanding of the operations of Primus subsequent to consummation of the
recently completed TresCom Merger. See"--Liquidity and Capital Resources."

                                   BUSINESS
 
GENERAL
 
 Primus
 
  Primus is a facilities-based global telecommunications company that offers
international and domestic long distance and other telecommunications services
to business, residential and carrier customers in North America, and selected
markets within the Asia-Pacific region and Europe. Primus has expanded its
geographic presence in Latin America through its recent acquisition of
TresCom, which provides international long distance service primarily for
calls originating in the United States. The Company seeks to capitalize on the
increasing demand for high-quality international telecommunications services
resulting from the globalization of the world's economies and the worldwide
trend toward telecommunications deregulation. Primus provides these services
over its Network, which includes (i) ten international gateway switches in the
United States, Australia, Canada, Puerto Rico and the United Kingdom, (ii)
four domestic switches in Australia, (iii) a switching platform in Japan and
(iv) both owned and leased transmission capacity on undersea and land-based
fiber optic cable systems. The Network, along with resale arrangements and
foreign carrier agreements, allows the Company to offer quality service to
approximately 275,000 customers.
 
  Primus is a full-service carrier and has licenses and operations in the
United States, Australia, the United Kingdom, Japan and Canada, enabling it to
complete calls to more than 230 countries. The United States, Australia and
the United Kingdom are the most deregulated countries within the Company's
Service Regions and will serve as regional hubs for Primus's intended
expansion into additional markets as worldwide deregulation of
telecommunications markets continues. During the years ended December 31, 1996
and 1997, Primus had net revenue of $173.0 million and $280.2 million,
respectively. After giving pro forma effect to the TresCom Merger and the
TelePassport/USFI Acquisition, for the year ended December 31, 1997, the
Company would have had net revenue of $448.9 million.
 
  The Company primarily targets, on a retail basis, small- and medium-sized
businesses and ethnic residential customers with significant international
long distance traffic and, on a wholesale basis, other telecommunications
carriers and resellers with substantial international traffic. The Company
provides a broad array of competitively priced telecommunications services,
including international and domestic long distance services and private
networks, reorigination services, prepaid and calling cards and toll-free
services, as well as local, data, Internet and cellular services in Australia.
The Company markets its services through a variety of channels, including
through its direct sales force and independent agents, and through direct
marketing.
 
  The Company has constructed and is expanding the Network to reduce and
control costs, improve service reliability and increase flexibility to
introduce new products and services. Management believes that, as the volume
of telecommunications traffic carried on the Network increases, the Company
should continue to improve its profitability as it more fully utilizes its
Network capacity and realizes economies of scale. As customer demand justifies
the capital investment, Primus will seek to expand the Network through
additional investment in undersea and domestic fiber optic cable systems,
international gateway and domestic switching facilities, and international
satellite earth stations. Major components of the Network include the
following:
 
  Switches. Since December 31, 1996, when the Company operated one
international gateway switch in Washington, D.C., the Network has grown to
consist of 14 switches, including ten international gateway switches (New
York, Los Angeles, Washington, D.C., Toronto, Vancouver, London and Sydney,
and as a result of the recently completed TresCom Merger, Fort Lauderdale, New
York City and Guaynabo, Puerto Rico) and four domestic switches (Adelaide,
Brisbane, Melbourne and Perth), and a switching platform in Japan. The Company
also has 15 Pops in additional markets within its Service Regions. The
Company's international gateway switches will serve as the base for its global
expansion of the Network into new countries when customer demand justifies
such investment and as regulatory rules permit the Company to compete in new
markets. The Company is currently installing an additional international
gateway switch in Frankfurt, Germany and, by the end of 1999, intends to add
up to three switches in North America, two switches in Europe, one switch in
the Asia-Pacific region, and three switches in Latin America.
 
                                      59
<PAGE>
 
  Transmission Capacity. The Company owns and leases transmission capacity
which connects its switches to each other and to the networks of other
international and domestic telecommunications carriers. The Company's
ownership interests consist of MAOUs and IRUs in 12 undersea fiber optic cable
systems, including the CANTAT-3, TAT-12/TAT-13, TPC-5 and Gemini systems. As a
result of the recently completed TresCom Merger, the Company has acquired
additional MAOUs and IRUs in 11 cable systems, including the Americas 1,
Columbus 2, PTAT-1 and Taino Caribe systems. The Company expects to continue
to acquire additional capacity on both existing and future international and
domestic fiber optic cable systems as anticipated customer demand justifies
such investments.
 
  Foreign Carrier Agreements. In selected countries where competition with the
traditional incumbent PTTs is limited or is not currently permitted, the
Company has entered into foreign carrier agreements with PTTs or other service
providers which permit the Company to carry traffic into and receive return
traffic from these countries. The Company has existing foreign carrier
agreements with PTTs in Cyprus, Greece, Honduras, India, Iran, Italy and New
Zealand, and additional carrier agreements with foreign service providers in
five other countries. As a result of the recently completed TresCom Merger,
the Company has acquired 27 additional foreign carrier agreements, providing
access to various countries in Latin America.
 
 TresCom Merger
 
  On June 9, 1998, pursuant to the Merger Agreement, the Company acquired all
of the outstanding shares of TresCom. The TresCom Merger provides Primus with
accelerated entry into the Latin American international long distance markets
and expands the scope and coverage of the Network, thereby providing
additional opportunities to migrate traffic onto the Network, obtaining better
utilization of the Network and variable costs. The Company believes that, in
addition to providing transmission facilities, the TresCom Merger adds foreign
carrier agreements, direct connections to foreign telecommunications carriers
and experienced management, enabling the combined Company to realize synergies
in sales, marketing and administration.
 
 TresCom
 
  TresCom is a facilities-based long-distance telecommunications carrier
focused on international long distance traffic originating in the United
States and terminating in Latin America. TresCom offers a broad array of
services, including long distance, calling cards, prepaid debit cards,
domestic and international toll-free calling and frame relay. TresCom provides
its customers with international long distance service and is able to complete
calls to approximately 230 countries and territories through an international
network consisting of: (i) owned facilities, concentrated in a Caribbean hub
linking the United States, the Caribbean, South America and Central America;
(ii) direct operating and transit agreements with various PTTs and TAs; and
(iii) owned and leased transmission capacity. TresCom also provides local
service in Puerto Rico and the United States Virgin Islands ("U.S.V.I.").
 
  A substantial portion of TresCom's business is providing services on a
wholesale basis to other telecommunications carriers and resellers. TresCom
also markets on a retail basis to residential and commercial customers,
ranging in size from small businesses to Fortune 500 companies. To take
advantage of the benefits associated with its network, TresCom targets its
United States mainland sales and marketing efforts towards customers with
significant international long distance traffic to Latin America. These
customers include businesses with sales or operations in Latin America, as
well as the growing Hispanic population in the United States. During 1997,
TresCom further increased its sales and marketing efforts directed towards
residential and commercial customers, while maintaining its carrier and
reseller customer base. In emerging markets in Latin America, TresCom has
teamed up with local agents and has begun generating international traffic
originating from those markets.
 
  TresCom transmits customer calls through an international network consisting
of ownership interests in undersea digital fiber optic transmission cables and
leased capacity from other carriers linking the United States, Europe and
Latin America. TresCom's owned network also includes wholly-owned microwave
relay and satellite
 
                                      60
<PAGE>
 
earth station equipment linking the mainland United States, Puerto Rico and
the U.S.V.I. TresCom's international network is further composed of leased
capacity from other carriers and direct operating and transit agreements with
PTTs and TAs. TresCom uses leased capacity to provide long-distance services
in areas where it does not own transmission facilities and to provide
redundancy where it does own such facilities. TresCom's contracts with PTTs
and TAs typically have terms ranging from one to five years, with clauses
providing for negotiated renewals.
 
  TresCom employs a direct sales force, numbering approximately 80 individuals
as of June 15, 1998, and independent sales and telemarketing agents to market
its services. TresCom maintains sales offices in Florida, New York, Puerto
Rico and St. Thomas, U.S.V.I. As part of TresCom's marketing activities to
residential customers, TresCom has entered into joint marketing and
promotional arrangements with other companies, including Coca-Cola, Shell Oil
Company, Seagrams and Walgreens Drug Stores. Additionally, TresCom utilizes
direct mail, participates in a variety of promotional activities which target
specified customers, and sponsors various civic and charity activities.
 
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 that has resulted, and is expected to continue to
result, in significant growth in usage of international telecommunications
services. According to TeleGeography, in 1996, the international long distance
industry accounted for $61 billion in revenues and 70 billion minutes of use,
up from $22 billion in revenues and 17 billion minutes of use in 1986.
According to TeleGeography, it is estimated that by the year 2000 this market
will have expanded to $86 billion in revenues and 122 billion minutes of use,
representing compound annual growth rates from 1996 of 9.0% and 15.0%,
respectively.
 
  The Company believes the growth in international long distance services is
being driven by (i) globalization of the world's economies and the worldwide
trend toward telecommunications deregulation, (ii) declining prices and a
wider choice of products and services driven by greater competition resulting
from privatization and deregulation, (iii) increased telephone accessibility
resulting from technological advances and greater investment in
telecommunications infrastructure, including deployment of wireless networks,
and (iv) increased international business and leisure travel. The Company
believes that growth of traffic originated in markets outside the United
States will 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
resulted in lower 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 Primus currently competes. 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. The Company believes 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 FCC data which management believes is
publicly available, for the period 1989 through 1996, per minute settlement
payments by United States-based carriers to foreign PTTs fell 38.6%, from
$0.70 per minute to $0.43 per minute while, over this same period, per minute
international billed revenue fell only 27.5%, from $1.02 in 1989 to $0.74 in
1996. The Company believes 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. See "Risk Factors--Intense
Domestic and International Competition."
 
  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
 
                                      61
<PAGE>
 
(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, Telstra in
Australia, NTT in Japan, Teleglobe in Canada and Telmex in Mexico.
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 RBOCs and, most recently, by the passage of the
1996 Telecommunications Act. Deregulation has occurred elsewhere, such as in
the United Kingdom and Australia, and is being implemented in other countries,
including most European Union countries, Japan and several Latin American
countries, including Chile, Brazil and Argentina.
 
  On February 15, 1997, the United States and 68 other countries, including
Australia, the United Kingdom, Canada, Germany and Japan, signed the WTO
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. The Company
believes that the WTO Agreement will provide it with significant opportunities
to compete in markets where it did not previously have access, and allow it to
provide end-to-end, facilities-based services to and from these countries.
 
  In addition, the FCC recently released an order that significantly changes
United States regulation of international services in order to implement the
United States' "open market" commitments under the WTO Agreement. Among other
measures, the FCC's order (i) eliminated the FCC's Effective Competitive
Opportunities ("ECO") test for applicants affiliated with carriers in WTO
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. The Company believes that the recent FCC order will have
the following effects on United States carriers: (i) reduce impediments to
investment in United States carriers by foreign entities, (ii) increase
opportunities to enter into innovative traffic arrangements with foreign
carriers located in WTO member countries, (iii) add new opportunities to
engage in ISR to additional foreign countries and (iv) 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 is calls going
from a country of origination, and inbound traffic is 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
IRUs
 
                                      62
<PAGE>
 
or MAOUs. The fundamental difference between an IRU holder and an owner of
MAOUs is that the IRU 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 ("ARM"),
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 ("TAR"). 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 TAR, 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 TAR 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 ("return 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.
 
  Alternative Calling Procedures. As the international long distance market is
being deregulated, long distance companies have devised alternative calling
procedures ("ACPs") in order to complete calls more economically than under
the ARM. Some of the more significant ACPs include (i) transit, (ii) refiling
or "hubbing," (iii) ISR and (iv) reorigination. The most common method is
transit which 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 ISR, 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. ISR 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 ACPs 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 ACPs and are developing
networks to compete with the first-tier carriers and gain market share. Other
entrants, including the Company, 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
 
  Primus's objective is to become a leading global provider of international
and domestic long distance voice, data and other services in its Service
Regions. Key elements of Primus's strategy to achieve this objective include:
 
  . Focus on Customers with Significant International Long Distance
    Usage. The Company's primary focus is providing telecommunications
    services, on a retail basis, to small- and medium-sized businesses with
    significant international long distance traffic, to ethnic residential
    customers and, on a wholesale basis, to other telecommunications carriers
    and resellers with international traffic. The Company believes 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. The Company seeks
    to be an early entrant into selected deregulating telecommunications
    markets where it believes there is significant demand for international
    long distance services as well as substantial growth and profit
    potential. The Company believes that early entrance into deregulating
    markets provides it with competitive advantages as it develops sales
    channels, establishes a customer base, hires personnel experienced in the
    telecommunications industry and achieves name recognition, prior to the
    entry into these markets by a large number of competitors. The Company
    focuses its expansion efforts on major metropolitan areas with high
    concentrations of potential customers with international traffic.
 
  . Expand Global Intelligent Network. Primus expects that continued
    strategic development of its Network will lead to reduced transmission
    and other operating costs as a percentage of net revenue, reduced
    reliance on other carriers and more efficient network utilization. The
    Company owns and operates its own switching facilities, and purchases
    fiber optic cable capacity on an end-to-end basis when current and
    expected traffic levels justify such investment.
 
  . Deliver Quality Services at Competitive Prices. Management believes that
    the Company delivers high quality services at competitive prices and
    provides a high level of customer service. The Company intends to
    maintain a low cost structure in order to offer its customers
    international and domestic long distance services priced below those of
    major carriers in the Service Regions. In addition, the Company intends
    to maintain strong customer relationships through the use of trained and
    experienced sales and service representatives, and through the provision
    of customized billing services.
 
  . Expand Service Offerings as Markets Deregulate. The Company typically
    enters markets which are in the initial stages of deregulation by first
    providing international long-distance services and, as the market
    deregulates further, expanding its portfolio of service offerings within
    the particular market. Management believes that international long
    distance generally offers attractive margins in markets in the early
    stage
 
                                      64
<PAGE>
 
   of deregulation and provides a platform for capturing customers for
   additional services. Subsequent additions to service offerings may
   include, among other services, domestic long distance, data and Internet
   access.
 
  .  Growth through Selected Acquisitions and Strategic Investments. As part
     of its business strategy, the Company frequently evaluates potential
     acquisitions, joint ventures and strategic investments. The Company
     views acquisitions, joint ventures and strategic investments as a means
     to enter additional markets and expand its operations within existing
     markets, thereby facilitating an acceleration of its business plan.
     Potential candidates include voice and data service providers with an
     established customer base, complementary operations, telecommunications
     licenses, experienced management or network facilities in countries into
     which the Company seeks 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 the Company provides its
services and a description of the Company's operations in each of its four
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 $17.1 billion from international services
(representing 17.2% of the total market). AT&T is the largest long distance
carrier in the United States market, with market share of approximately 50.2%
of international outgoing minutes in 1996. MCI and Sprint had market shares of
28.4% and 13.2%, respectively in 1996. AT&T, MCI 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 WorldCom, Frontier and LCI, 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, Primus provides long distance services to small- and
medium-sized businesses, residential customers, and other telecommunication
carriers. The Company operates international gateway telephone switches in the
New York City area, Washington D.C. and Los Angeles which are connected with
European countries and countries in the Asia-Pacific region through owned and
leased international fiber cable systems. The Company maintains a direct sales
organization in each of these cities to sell to business customers, and has a
telemarketing center for small business sales in Tampa. To reach residential
customers, the Company advertises nationally in ethnic newspapers and other
publications, offering discounted rates for international calls to targeted
countries. The Company utilizes independent agents to reach and enhance sales
to both business and residential customers and has established a direct sales
force for marketing wholesale international services to other long distance
carriers. The Company maintains a national customer service center staffed
with multi-lingual representatives and operates a global Network Management
Center that monitors the Network from its McLean, Virginia location.
 
  As a result of the recently completed TresCom Merger, the Company has
acquired all of the operations and facilities of TresCom. In the United
States, TresCom markets wholesale telecommunications services to other long
distance carriers who utilize the TresCom network to transmit international
calls to Latin America. TresCom's customers also include businesses with sales
or operations in Latin America, as well as the growing Hispanic population in
the United States. TresCom employs a direct sales force, numbering
approximately 80 individuals as of June 15, 1998, and independent sales and
telemarketing agents to market its services. TresCom maintains sales offices
in Florida, New York, California, Georgia, Puerto Rico and St. Thomas,
U.S.V.I. As part of TresCom's marketing activities to residential customers,
TresCom has entered into joint marketing and promotional arrangements with
other companies, including Coca-Cola, Shell Oil Company, Seagrams and
Walgreens Drug Stores. Additionally, TresCom utilizes direct mail,
participates in a variety of promotional activities which target specified
customers, and sponsors various civic and charity activities.

  According to the International Telecommunications Union ("ITU"), 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, is the largest provider of long distance services with a
market share of approximately 67% in 1997. Two types of long distance
providers compete with Stentor. The first, which includes AT&T LDS, fONOROLA
and Sprint Canada, own and operate interexchange circuits and offer
essentially the same services as Stentor. 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
associations. In Canada, Primus Canada provides long distance services to
small- and medium-sized businesses, residential customers and other
telecommunication carriers. Primus Canada operates switches in Toronto and
Vancouver, maintains points-of-presence in Ottawa, Montreal and Calgary, and
has sales and customer service offices in Vancouver, Toronto, and Montreal.
 
  According to the ITU, 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) to
operate as facilities-based long distance carriers. Resale of basic switched
voice long distance services, however, is still not allowed in Mexico. Primus
provides customers with United States-Mexico cross border private line
services, but is prohibited by the private ownership limitations from
providing other services.
 
  As of June 15, 1998, the Company had approximately 25,000 business customers
and 95,000 residential customers in North America, including the recently
acquired TresCom customer base.
 
  Asia-Pacific. According to the ITU, in 1996, the total telecommunications
market in Australia accounted for approximately $13.4 billion in revenues.
Telstra and 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 market share of approximately 62.0% in 1996.
In addition to the Company and Optus, 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 Optus to
own domestic transmission facilities and mandating Telstra to provide equal
(non-code) access to customers of select service providers such as the
Company. The Company is a licensed carrier permitted to own and operate
transmission facilities in Australia.
 
  Primus is the fourth largest long distance company in Australia, 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. The
Company has invested substantial resources over the past two years to build a
domestic and international long distance network to transform its Australian
operations into a full facilities-based telecommunications carrier. During
1997, the Company installed and began operating a five-city switched network
using Northern Telecom switches in Sydney, Melbourne, Perth, Adelaide, and
Brisbane. The Company purchased international fiber cable capacity during 1997
and linked the Australian network to the United States via the TPC-5, APCN,
and Jassaurus cable systems, as well as to New Zealand. Primus Australia
became a fully licensed facilities-based telecommunications carrier on July 1,
1997. In August 1997, equal access was introduced in Australia, and the
Company began the process of migrating and connecting customers directly to
its own Network. In 1998, the Company completed the Hotkey Investment and the
Eclipse Acquisition, positioning it to offer a complete range of
telecommunications services for corporate customers in Australia, including
fully integrated voice and data networks, as well as Internet access. The
Company markets its 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
 
                                      66
<PAGE>
 
volume of international calls. As of June 15, 1998, the Company had
approximately 25,000 business customers and 105,000 residential customers in
Australia.
 
  The Company entered the Japanese market in late 1997 through the
TelePassport/USFI Acquisition. According to the ITU, in 1996, the total
telecommunications market in Japan accounted for approximately $93.6 billion
in revenues. The Company maintains an office in downtown Tokyo and a switching
platform to provide international calling services to resellers and small
businesses. The Company has interconnected its Tokyo switch to Los Angeles via
the TPC-5 fiber cable system. The Company plans to apply for a full Class-I
carrier license in Japan. The Company plans to market its services in Japan
through direct sales and relationships that it is establishing with business
partners.
 
  Europe. Oftel estimates that the market for international and domestic long
distance services in the United Kingdom accounted for approximately $6.6
billion in revenues in the 12 months ended March 31, 1996. In the United
Kingdom, British Telecom historically has dominated the telecommunications
market and is the largest carrier. Mercury, which owns and operates
interchange 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, WorldCom, MFS, ACC and
Esprit.
 
  Primus Telecommunications, Ltd. is a fully licensed carrier in the United
Kingdom and provides domestic and international long distance services to
residential customers, small businesses, and other telecommunications
carriers. The Company operates an Ericsson AXE-10 international gateway
telephone switch in London, which is directly connected to the United States
and will be directly connected to the international gateway switch currently
being installed in Frankfurt, Germany. Primus's European operations are
headquartered in London, where it also maintains a 24-hour customer service
call center. The Company markets its 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. As of June 15, 1998, Primus Telecommunications, Ltd. had approximately
25,000 residential customers in the United Kingdom.
 
  The Company is in the process of expanding its services and Network to
continental Europe which has recently begun the process of deregulation of its
telecommunications markets. For example, the Company was recently awarded a
Class-4 switched voice telephone license in Germany. According to the ITU, in
1996, the German telecommunications market generated approximately $44.6
billion in revenues. Through the TelePassport/USFI Acquisition, Primus
acquired a base of small business customers in Germany to whom it provides
reorigination services, establishing a platform for the Company's expansion
into that market. Additionally, the Company has opened its first sales office
in Frankfurt, and has purchased an Ericsson AXE-10 international gateway
switch which is currently being installed. The Company has also applied for a
license and expects to begin operations in France during 1998.
 
  Latin America. As a result of the recently completed TresCom Merger, the
Company will accelerate the targeting of businesses and residential customers
in Latin America to capitalize on the existing TresCom relationships with
customers having operations in those countries. TresCom offers international
inbound calling services which provide collect calling from parts of Latin
America to the United States and calling card services with United States
terminations. In 1997, TresCom began marketing these services in Honduras,
Nicaragua and Panama. Additionally, TresCom began providing international
callthrough services from portions of Latin America enabling its customers
located in that region to place international calls at reduced rates. TresCom
maintains a multi-lingual customer service department available through "toll-
free" access, as well as a "Trouble Reporting Center" which caters to its
wholesale customers. In addition to international long distance services,
TresCom provides local service in Puerto Rico, and the U.S.V.I.
 
SERVICES
 
  The Company offers a broad array of telecommunications services through the
Network and through interconnection with the networks of other carriers. The
Company's decision to offer certain services in a market
 
                                      67
<PAGE>
 
is based on competitive factors and regulatory restraints within the market.
Below is a summary of services offered by the Company:
 
  . International and Domestic Long Distance. The Company provides
    international long distance voice services terminating in approximately
    230 countries, and provides domestic long distance voice services within
    selected countries within its 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, the Company designs and
    implements international private network services that may be used for
    voice, data and video applications.
 
  . Prepaid Cards, Calling Cards and Collect Calling. The Company offers
    prepaid and calling cards that may be used by customers for domestic and
    international telephone calls both within and outside of their home
    country. If the TresCom Merger is consummated, the Company will offer
    customers in selected Latin American markets collect calling services to
    the United States and calling card services for calls terminating in the
    United States. TresCom is currently marketing such services in Honduras,
    Nicaragua and Panama.
 
  . Reorigination and Callthrough Services. In selected countries, including
    Germany and Japan, the Company provides 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. As a result of the recently completed TresCom Merger, the Company
    also offers international callthrough services from selected countries in
    Latin America.
 
  . Local Switched Services. The Company in the future intends to provide
    local service on a resale basis as part of its "multi-service" marketing
    approach, subject to commercial feasibility and regulatory limitations.
    The Company currently provides local service in Australia and, as a
    result of the recently completed TresCom Merger, provides competitively-
    priced local calling services within Puerto Rico and the U.S.V.I.
 
  . Toll-free Services. The Company offers domestic and international toll-
    free services.
 
  . Data Services. With the Hotkey Investment and the Eclipse Acquisition,
    the Company is positioned to offer ATM, a transmission standard which
    utilizes statistical multiplexing technology, and frame relay and other
    data services, including Internet access services, in Australia.
 
  . Cellular Services. The Company resells Telstra analog and digital
    cellular services in Australia.
 
NETWORK
 
  General. Since its inception in 1994, the Company has 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. Primus believes that the
Network allows it to control both the quality and cost of the on-net
telecommunications services it provides to its customers. To ensure high-
quality telecommunications services, the Network employs digital switching and
fiber optic technologies, uses SS7 signaling and is supported by comprehensive
monitoring and technical services. The Company's Network consists of (i) a
global backbone network connecting intelligent gateway switches in the Service
Regions, (ii) a domestic long distance network presence within certain
countries within the Service Regions, and (iii) a combination of owned and
leased transmission facilities, resale arrangements and foreign carrier
agreements.
 
  Each of the international gateway switches will be connected to the domestic
and international networks of both the Company and other carriers in a
particular market, allowing the Company to (i) provide seamless service, (ii)
package and market the voice and data services purchased from other carriers
under the "Primus" brand name and (iii) divert a portion of that market's
United States-bound return traffic through the Company's switches in the
United States. In addition, until the Company's customer base grows and it
penetrates other
 
                                      68
<PAGE>
 
deregulating telecommunications markets, the Company intends to transit a
significant portion of its traffic through the United States.
 
  The Company has targeted North America, the Asia-Pacific region, Europe and,
as a result of the recently completed TresCom Merger, Latin America, for the
development of the Network. The Company has selected the United States,
Australia and the United Kingdom as regional hubs for expansion into
additional markets within North America, the Asia-Pacific region and Europe,
respectively. These countries were selected based on their market size,
potential growth and favorable regulatory environments. The Company expects to
expand into additional markets as deregulation occurs and the Company is
permitted to offer a full range of switched public telephone services. For
instance, the Company is using its United Kingdom operations to coordinate
efforts to enter other major metropolitan European markets in the European
Union in conjunction with the deregulation of the telecommunications industry
in certain European Union countries which began in 1998. The initial step in
this expansion involves the Company's current installation of an international
gateway switch in Frankfurt, Germany.
 
  The following chart illustrates an international long distance call using
the Network from the United States to another market where the Company has an
international gateway switch:

                             [GRAPH APPEARS HERE] 
 
  International Gateway and Domestic Switches. As of March 31, 1998, the
Company operated 11 switches, including seven international gateway switches
(New York, Los Angeles, Washington, D.C., Toronto, Vancouver, London, Sydney),
four domestic switches (Adelaide, Brisbane, Melbourne and Perth) and a
switching platform in Japan. As a result of the recently completed TresCom
Merger, the Company has acquird three additional international gateway
switches located in Fort Lauderdale, New York City and Guaynabo, Puerto Rico.
The Company also currently operates approximately 15 Pops in other major
metropolitan areas of its Service Regions. The equipment deployed in the
Network, including the switches, consists primarily of equipment manufactured
by Nortel, Ericsson and Siemens.
 
  Fiber Optic Cable Systems. Where the Company's customer base has developed
sufficient traffic, the Company has purchased and leased undersea and land-
based fiber optic cable transmission capacity to connect to its various
switches. Where traffic is light or moderate, the Company obtains capacity to
transmit traffic on a per-minute variable cost basis. When traffic volume
increases and such commitments are cost effective, the Company intends to
either lease or purchase lines on a monthly or longer term basis at a fixed
cost and acquire
 
                                      69
<PAGE>
 
economic interests in transmission capacity through MAOUs and IRUs to
international traffic destinations. The following chart sets forth a listing
of the undersea fiber optic cable systems in which the Company has capacity
after the recently completed TresCom Merger (which includes both MAOUs and
IRUs):

  Foreign Carrier Agreements. In selected countries where competition with the
traditional incumbent PTTs is limited or is not currently permitted, the
Company has entered into foreign carrier agreements with PTTs or other service
providers which permit the Company to provide traffic into and receive return
traffic from these countries. The Company has existing foreign carrier
agreements with PTTs in Cyprus, Greece, Honduras, India,
 
                                      70
<PAGE>
 
Iran, Italy and New Zealand, and additional agreements with other foreign
carriers in 5 other countries. As a result of the recently completed TresCom
Merger, the Company has acquired 27 additional foreign carrier agreements,
providing access to various countries in Latin America.
 
  Network Management and Control. The Company owns and operates a network
management control center (a "NMCC") in Sydney, Australia which is used to
monitor and control all switches and other transmission equipment used in its
Australia Network. This NMCC operates seven days a week, 24 hours per day, 365
days a year. In the United States, United Kingdom and Canada, the Company
currently monitors and controls each switch locally. The Company has begun to
construct a NMCC in McLean, Virginia, and plans to use a portion of the net
proceeds of this Offering to build a new NMCC in London and to upgrade the
existing Sydney NMCC. Each of the NMCCs will be capable of monitoring and
controlling the Network in all regions.
 
  Planned Expansion of Network. The Company is currently installing an
additional international gateway switch in Frankfurt, Germany and, by the end
of 1999, intends to add up to three switches in North America, two switches in
Europe, one switch in Asia-Pacific and three switches in Latin America.
Additionally, the Company intends to continue to invest in additional switches
and Pops in major metropolitan areas of the Service Regions as the traffic
usage warrants the expenditure. The Company also intends to acquire capacity
in land based fiber optic cable systems in its Service Regions, particularly
in North America and Europe. To augment the Network, the Company intends to
construct and own international satellite earth stations to connect the
Network to developing countries in which fiber optic cable connections are
unavailable or uneconomical.
 
CUSTOMERS
 
  The Company's primary focus is providing telecommunications services, on a
retail basis, to small- and medium-sized businesses with significant
international long distance traffic and ethnic residential consumers and, on a
wholesale basis, other carriers and resellers with international traffic. As
of June 15, 1998, Primus had in excess of 275,000 customers, including the
recently acquired TresCom customer base.
 
  Businesses. The Company's business sales and marketing efforts target small-
and medium-sized businesses with significant international long distance
traffic. The Company believes that these users are attracted to the Company
primarily due to its price savings compared to first-tier carriers and,
secondarily, its personalized approach to customer service and support,
including customized billing and bundled service offerings.
 
  Residential Consumers. The Company's residential sales and marketing
strategy targets ethnic residential consumers who generate high international
traffic volumes. The Company believes that they are attracted to the Company
because of price savings as compared to first-tier carriers, simplified
pricing structure, and multilingual customer service and support.
 
  Telecommunications Carriers and Resellers. The Company competes 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
the Company maximize the utilization of the Network and thereby reduce the
Company's fixed costs per minute of use.
 
  Customer Service. The Company strives to provide personalized customer
service and believes that the quality of its customer service is one of its
competitive advantages. The Company's larger customers are actively covered by
dedicated account and service representatives who seek to identify, prevent
and solve problems. The Company provides toll-free, 24-hour a day customer
service in the United States, Canada, the United Kingdom and Australia. As of
June 15, 1998, the Company employed approximately 190 full-time customer
service employees, many of whom are multi-lingual. The Company intends to
integrate the TresCom staff of operators fluent in English and Spanish, which
can be accessed to complete collect, third party, person-to-person, station-
to-station and credit card validation calls. The TresCom Merger will
accelerate the Company's ability to offer wholesale and retail traffic
repricing for international and domestic traffic, as well as advanced personal
computer billing services. TresCom also maintains a "Trouble Reporting Center"
for its wholesale customers.

SALES AND MARKETING
 
  The Company markets its services through a variety of sales channels, as
summarized below:
 
  Direct Sales Force. The Company's direct sales force is comprised of full-
time employees who focus on small- to medium-sized business customers with
substantial international traffic or traffic potential. The Company also
employs 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.
 
  The Company's direct sales efforts are organized into regional sales
offices. The Company currently has offices in Washington, D.C., New York City,
Los Angeles, Tampa, Toronto, Vancouver, Montreal, Mexico City, London,
Frankfurt, Melbourne, Sydney, Adelaide, Brisbane, Perth and Tokyo. With the
recent completion of the TresCom Merger, the Company has additional sales
offices in Fort Lauderdale, Puerto Rico and St. Thomas, U.S.V.I.
 
  Agents and Independent Sales Representatives. The Company supplements its
direct sales efforts with agents and independent sales representatives. These
agents and representatives, who typically focus on small- and medium-sized
businesses, as well as ethnic residential consumers, are paid commissions
based on long distance revenue generated. Within major metropolitan regions,
the Company usually grants only nonexclusive sales rights, requires its agents
and representatives to maintain minimum quotas and prohibits them from selling
competitors' products.
 
  Telemarketing. The Company employs full-time telemarketing sales personnel
to supplement sales efforts to ethnic residential consumers and small- and
medium-sized business customers.
 
  Media and Direct Mail. The Company uses a variety of print, television and
radio advertising to increase name recognition and generate new customers. The
Company reaches ethnic residential consumers by print advertising campaigns in
ethnic newspapers, and advertising on select radio and television programs.
 
MANAGEMENT INFORMATION AND BILLING SYSTEMS
 
  The Company uses various management information, network and customer
billing systems in its different operating subsidiaries to support the
functions of network and traffic management, customer service and customer
billing. For financial reporting, Primus utilizes a common system in each of
its markets. It is expected that TresCom's financial reporting will be
integrated with that of the Company. For its billing requirements in the
United States, the Company uses a customer billing system developed by
Electronic Data Systems Inc. ("EDS") which supplies, operates and maintains
this system and is responsible for providing back-up facilities and disaster
recovery. The EDS system is widely used in the telecommunications industry and
has been customized to meet the Company's specific needs. Elsewhere, the
Company uses advanced systems to handle its billing requirements. The Company
direct bills all of its business, resellers and residential customers in all
of its Service Regions.
 
  Management believes that its financial reporting and billing systems are
adequate to meet the Company's needs in the near term, including integration
of TresCom's operations, but as the Company continues to grow, it will need to
invest additional capital to purchase hardware and software, license more
specialized software, increase capacity and link its systems among different
countries. The Company is reviewing its computer systems and operations to
identify and determine the extent to which any systems will be vulnerable to
potential errors and failures as a result of the Year 2000 problem. See "Risk
Factors--Dependence on Effective Information Systems; Year 2000 Problem" and
"Management's Discussion and Analysis of Financial Condition and Results of
Operations--Year 2000 Compliance."

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. The Company believes 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, the
Company has numerous competitors. The Company believes 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 calls in the markets in which the Company competes
have declined historically and are likely to continue to decrease. Many of the
competitors are significantly larger, have substantially greater financial,
technical and marketing resources and larger networks than the Company. See
"Risk Factors--Intense Domestic and International Competition."
 
  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, RBOCs will be allowed to
enter the long distance market, AT&T, MCI 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 European
Union 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 the 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 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, Sprint and WorldCom being the next largest providers. In the future,
under provisions of recently enacted federal legislation, the Company
anticipates that it will also compete with RBOCs, LECs and Internet providers
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 the Company. The Company
competes with facilities-based carriers, other resellers and rebillers,
primarily on the basis of price. The principal facilities-based competitors
include the Stentor Companies, in particular, Bell Canada, the dominant
supplier of local and long-distance services in Canada, AT&T LDS, Sprint
Canada and fONOROLA. The Company also competes with ACC Canada, one of the
large resellers. Based upon current market share estimates, the Stentor
Companies control approximately 70% of the entire Canadian long distance
market and approximately 66% of the business long distance market.
 
  Asia-Pacific. Australia is one of the most deregulated and competitive
telecommunications markets in the Asia-Pacific region. The Company's principal
competitors in Australia are Telstra, the dominant carrier, Optus and AAPT and
a number of other switchless resellers. The Company competes 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. The Company believes that competition in Australia will increase as
more companies are awarded carrier licenses in the future. The Company's
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,
WorldCom and ATNet.
 
  Europe. The Company's 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, Esprit Telecom Group and RSL
 
                                      73
<PAGE>
 
Communications. The Company competes in the United Kingdom, and expects to
compete in other European countries, by offering competitively-priced bundled
and stand-alone services, personalized customer service and value-added
services. The Company's principal competitor in Germany is Deutsche Telekom,
the dominant carrier. The Company also competes with O.tel.o Communications,
Mannesmann ARCOR, VIAG Interkom, MobilCom, Talkline, MFS/Colt, WorldCom,
PlusNet, and RSL Communications. Additionally, the Company also faces
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".
 
  Latin America. The Company's principal competitors in Latin America are the
traditional PTTs in each country within this region, including Telmex in
Mexico.
 
GOVERNMENT REGULATION
 
  As a global telecommunications company, the Company is subject to varying
degrees of regulation in each of the jurisdictions in which it provides its
services. Local laws and regulations, and the interpretation of such laws and
regulations, differ significantly among the jurisdictions in which the Company
operates. There can be no assurance that future regulatory, judicial and
legislative changes will not have a material adverse effect on the Company,
that domestic or international regulators or third parties will not raise
material issues with regard to the Company's compliance or noncompliance with
applicable regulations or that regulatory activities will not have a material
adverse effect on the Company. See "Risk Factors--Potential Adverse Effects of
Regulation."
 
  Regulation of the telecommunications industry is changing rapidly both
domestically and globally. The FCC 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. The Company is 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 WTO Agreement, which reflects efforts
to dismantle government-owned telecommunications monopolies throughout Europe
and Asia may affect the Company. Although the Company believes 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 the Company.
 
  The regulatory framework in certain jurisdictions in which the Company
provides its services is described below:
 
 United States
 
  In the United States, the Company's services are subject to the provisions
of the Communications Act, 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, the Company 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. The Company is
classified as a non-dominant common carrier for domestic service and is not
required to obtain specific prior FCC approval to initiate or expand domestic
interstate services.
 
  International Service Regulation. International common carriers, including
the Company, 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. The Company has 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.
 
 
                                      74
<PAGE>
 
  In addition to the general common carrier principles, the Company must
conduct its 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. Under the
ISP, absent approval from the FCC, international telecommunications service
agreements with foreign carriers must provide that settlement rates paid to
each party are one-half of the accounting rate, and U.S. carriers may not
accept more than a proportionate share of return traffic. The ISP also
provides for a mechanism by which the FCC can review the rates contained in
such foreign carrier agreements. The FCC could find that the Company does not
meet certain ISP requirements with respect to certain of the Company's foreign
carrier agreements. Although the FCC generally has not issued penalties in
this area, it could, among other things, issue a cease and desist order,
impose fines or allow the collection of damages if it finds that the Company
is not in compliance with the ISP. The Company does not believe that any such
fine or order would have a material adverse effect on the Company.
 
  The Company is also subject to other FCC requirements regarding the routing
of telecommunications services between the United States and foreign
countries. These requirements include compliance with the FCC's limitations on
the routing of international traffic via international private lines and on
accepting "special concessions" from certain carriers, as well as the filing
of periodic reports with the FCC. In implementing the WTO Agreement, the FCC
recently reduced the applicability of some of these requirements to the
activities of telecommunications carriers such as the Company. Moreover, the
Company has a number of customers in foreign countries that access the
Company's services through international call reorigination. In providing
service to these customers, the Company is required by the FCC to offer such
services in compliance with the laws of foreign countries where its customers
are located. Certain countries prohibit some or all forms of call
reorigination. For example, Honduras and Nicaragua have informed the
International Telecommunications Union that they prohibit call reorigination.
The Company may be prevented in the future from providing such services or
penalized either by the foreign country or, in certain circumstances, by the
FCC.
 
  The FCC continues to refine its international service rules, including ISP
requirements, to promote competition, reflect and encourage liberalization in
foreign countries and reduce accounting rates toward cost. In that regard, the
FCC has determined that it would permit U.S. carriers to enter into "flexible"
international termination arrangements where such arrangements promote
competition. Under this new policy, the FCC has allowed the Company to enter
into an alternative termination arrangement with its Australian subsidiary
Axicorp, which allows the Company and Axicorp to terminate each other's
traffic under favorable terms that deviate from the ISP.
 
  Domestic Service Regulation. The Company is considered a non-dominant
domestic interstate carrier subject to minimal regulation by the FCC. The
Company is not required to obtain FCC authority to expand its domestic
interstate operations, but is required to maintain a tariff on file at the
FCC. The 1996 Telecommunications Act is intended to increase competition in
the U.S. telecommunications markets. The legislation opens the local services
markets by requiring LECs to permit interconnection to their networks and by
establishing LEC obligations with respect to unbundled access, resale, number
portability, dialing parity, access to rights-of-way, mutual compensation and
other matters. In addition, the legislation codifies the LECs' equal access
and nondiscrimination obligations and preempts inconsistent state regulation.
The legislation also contains special provisions that eliminate the
restrictions on incumbent LECs such as the RBOCs and the GTE Operating
Companies (the "GTOCs") from providing long distance services. These new
provisions permit an RBOC to enter the "out-of-region" long distance market
immediately upon the receipt of any state and/or federal regulatory approvals
otherwise applicable to the provision of long distance service. These new
provisions also permit an RBOC to enter the "in-region" long distance market
if it satisfies procedural and substantive requirements, including obtaining
FCC approval upon a showing that in certain situations facilities-based
competition is present in its market, and that it has entered into
interconnection agreements which satisfy a 14-point "checklist" of competitive
requirements. The GTOCs are permitted to enter the long distance market as of
the date of enactment of the 1996 Telecommunications Act, without regard to
limitations by region, although necessary regulatory approvals to provide long
distance services must be obtained, and the GTOCs are subject to the
provisions of the 1996
 
                                      75
<PAGE>
 
Telecommunications Act that impose interconnection and other requirements on
LECs. The 1996 Telecommunications Act also addresses a wide range of other
telecommunications issues that may potentially impact the Company's
operations. It is unknown at this time precisely the nature and extent of the
impact that the legislation will have on the Company. On August 1, 1996, the
FCC adopted an Interconnection Order implementing the requirements that
incumbent LECs make available to new entrants interconnection and unbundled
network elements, and offer retail services for resale at wholesale rates.
Portions of that order were vacated by the U.S. Court of Appeals for the
Eighth Circuit. The U.S. District court for the Northern District of Texas
recently ruled that the long distance conditions in Sections 271-275 of the
1996 Telecommunications Act are unconstitutional. Higher courts, including the
U.S. Supreme Court, will be reviewing some of these decisions. The result of
such review cannot be predicted and the Company could be adversely affected to
the extent that conditions of RBOC entry into the long distance market are
relaxed or eliminated.
 
  The Company's costs of providing long distance services will be affected by
changes in the access charge rates imposed by incumbent LECs for origination
and termination of calls over local facilities. The FCC has significantly
revised its access charge rules in recent years to permit incumbent LECs
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 1998 that may grant certain LECs
further flexibility.
 
  The FCC has also significantly revised the universal service subsidy regime
to be funded by interstate carriers 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 outcome of these proceedings or its effect on the
Company cannot be predicted.
 
  State Regulation. The Company's intrastate long distance operations are
subject to various state laws and regulations, including, in most
jurisdictions, certification and tariff filing requirements. The Company has
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. PSCs also regulate access
charges and other pricing for telecommunications services within each state.
The RBOCs and other local exchange carriers have been seeking reduction of
state regulatory requirements, including greater pricing flexibility which, if
granted, could subject the Company to increased price competition. The Company
may also be required to contribute to universal service funds in some states.
 
  Foreign Ownership Affiliations and Limitations. The Communications Act
limits the ownership of an entity holding a common carrier radio license by
non-U.S. citizens, foreign corporations and foreign governments. Through
TresCom, the Company holds common carrier wireless licenses. In its order
implementing the U.S. commitments under the WTO Agreement, the FCC established
new rules that effectively relax the foreign ownership limits for common
carrier wireless licensees. The new rules permit up to 100% foreign indirect
ownership of wireless licenses by foreign interests from members of the WTO.
FCC rules also require international carriers to notify the FCC 60 days in
advance of an acquisition of a 25% or greater controlling interest by a
foreign carrier in that U.S. carrier or an acquisition by the U.S. carrier of
a 25% or greater controlling interest in a foreign carrier. After receiving
this notification, the FCC can require the Company to meet certain "dominant
carrier" reporting and other conditions if the Commission finds that the
acquisition creates an affiliation with a dominant foreign carrier. In
addition, if the Company becomes affiliated with a dominant carrier from a
country that is not a member of the WTO, the FCC will apply an "effective
competitive opportunities" test and could prevent the Company from providing
services between the United States and that country. The effect on the Company
of the WTO Agreement or other new legislation, or the outcome of the FCC's
rulemaking regarding implementing WTO regulations which may become applicable
to the Company, cannot be determined.

 Canada
 
  Telecommunications carriers are regulated generally by the CRTC which has
enacted policies and regulations that include the establishment of
contribution charges (the equivalent of access charges in the U.S.),
deregulation of the international segment of the long-distance market,
limitations on switched hubbing through the United States and restrictions on
foreign ownership for facilities-based carriers. In addition, Canada has
committed in the WTO Agreement to eliminate a number of barriers to
competition, some of which are expected to be eliminated in October 1998.
Teleglobe Canada, Inc. ("Teleglobe"), which currently has a monopoly over
international transmission services until October 1, 1998, offers
international carrier service on a nondiscriminatory basis to both facilities-
based carriers and resellers, who may have direct access to its international
gateways. The Company is permitted to provide ISR of private leased lines to
any country which permits such arrangements on a reciprocal basis. Routing of
basic intra-Canada traffic or basic traffic destined to third countries
through U.S. facilities is, however, prohibited. Despite these restrictions,
Primus as a reseller is virtually unregulated by the CRTC. In particular,
because the Company does not own and operate transmission facilities in
Canada, it is not subject to the Canadian Telecommunications Act or the
regulatory authority of the CRTC. The Company may therefore provide resold
Canadian 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 ILECs 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
largest telephone companies to interconnect their networks with their
facilities-based as well as resale competitors. The dominant Stentor group of
companies, including Bell Canada, offers both local and long distance services
in the respective regions of each of the group's member telephone companies.
Other nationwide providers are AT&T Canada Long Distance Services, Sprint
Canada and fONOROLA, Inc. Additional long distance services competition is
provided by a substantial resale long distance industry in Canada. Although
resellers do not own facilities, they are able to provide the same range of
domestic services and long distance services as facilities-based carriers by
leasing capacity and other services from facilities-based carriers.
 
  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
companies 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. Based on Canada's commitment in the WTO Agreement, the restriction
on foreign investment in facilities-based telecommunications service providers
remains largely intact, but will be eliminated as October 1, 1998 for
operations conducted under an international submarine cable license and for
certain satellites.
 
 Australia
 
  The provision of the Company's services is subject to federal regulation.
Two primary instruments of regulation have been the Telecommunications Act
1991 and federal regulation of anti-competitive practices pursuant to the
Trade Practices Act. The regulatory climate changed in July 1997 with the
implementation of the Telecom Act. These latest changes to the regulatory
framework have been described by the Australian Government as the achievement
of the Government's long-term objective of an internationally competitive
telecommunications industry in Australia through full and open competition.
 
 
                                      77

   The Company is licensed under the Telecom Act to own and operate
transmission facilities in Australia. Under the new regulatory framework, the
Company does not require 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, the Company 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.
 
  Also, in connection with the Telecom Act, two federal regulatory authorities
now exercise control over a broad range of issues affecting the operation of
the Australian telecommunications industry. The ACA is the authority
regulating matters including the licensing of carriers and technical matters,
and the ACCC has the role of promotion of competition and consumer protection.
The Company is required to comply with the terms of its own license, is
subject to the greater controls applicable to licensed facilities-based
carriers and is under the regulatory control of the ACA and the ACCC. 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 the
Company.
 
  In the Australian context, a distinction is drawn in the Telecom Act between
carriers and other providers of telecommunications services. However,
distinctions are no longer drawn between types of carriers such as fixed or
mobile. Carriers are the providers of telecommunications infrastructure and
carriage service providers extend service to the end-users. In practice, most
carriers are expected also to be carriage service providers. There is now no
limit to the number of carriers who may be licensed, and it is expected that
additional licenses will be granted. As a result of the Telecom Act, 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. New carriers seeking
a license must provide an industry development plan approved by the Australian
Government. 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 Telecom Act, with certain commitments made in their industry
development plan and with the telecommunications access regime and related
facilities access obligations). The Company has submitted its industry
development plan to the Australian Government. The plan includes relevant
particulars of the carrier's strategic commercial relationships, R&D
activities, export development plans, and arrangements aimed at encouraging
employment in industries involved in the manufacture, development or supply of
facilities. A summary of the plan must be made available to the public.
Carriers must also meet the universal service obligation, to assist in
providing all Australians, particularly in remote areas, with reasonable
access to standard telephone services. The costs required to be paid by the
Company in connection with this obligation have not yet been determined by the
Australian government, but they are not expected to be material.
 
  Tariffs. The ACCC has access to various information on market conduct. The
ACCC's information gathering powers include: a requirement on Telstra to
continue to file tariffs with the ACCC about its basic carriage services,
unless the ACCC exempts it from this obligation; an ability to direct any
carrier or carriage service provider with a substantial degree of market power
to file tariff information; and an ability to set rules regarding the way
carriers or carriage service providers keep records so that, e.g., information
is kept in a form that will assist the ACCC in determining terms and
conditions of access under the telecommunications access regime.
 
  Tariff filing will essentially be an information gathering tool to
supplement the ACCC's general information gathering powers, and to assist in
identifying anticompetitive conduct such as predatory pricing and preferential
pricing to a related person. If, on the basis of the information provided in a
tariff filing, the ACCC forms the view that a carrier is engaging in
anticompetitive conduct, it may use its powers to stop that conduct.
 
  The ACCC may make tariff information publicly available if it is satisfied
there would be a public benefit (e.g., by enabling other industry players to
scrutinize the tariffs for anticompetitive purpose or effect, or to inform
 
                                      78
<PAGE>
 
the public). The ACCC will balance concerns about commercial confidentiality
and the promotion of competition against dealing with anticompetitive conduct
and informing the public.
 
  Fair Trading Practices. The ACCC will enforce legislation for the promotion
of competition and consumer protection, particularly rights of access
(including pricing for access) and interconnection. The ACCC will be able to
issue a competition notice to a carrier which has engaged in anticompetitive
conduct. Where a competition notice has been issued, the ACCC will be able to
seek pecuniary penalties, and other carriers will be able to seek damages, if
the carrier continues to engage in the specified conduct.
 
  The Telecom Act package of legislation includes a telecommunications access
regime that provides a framework for regulating access rights for specific
carriage services and related services. 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 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 regime establishes access rights through the declaration of services by
the ACCC. The ACCC may declare services to be the subject of regulated access,
either on the recommendation of the industry self-regulatory body or where,
following a public inquiry, the ACCC is satisfied that a declaration would be
in the long-term interests of end-users of telecommunications services. Once a
service is declared, carriers supplying that service are, unless otherwise
exempt, under an obligation to supply the declared service to other carriers
and service providers.
 
  Access providers must comply with their access obligations on conditions
negotiated between the access provider and access seeker; as detailed in an
access undertaking; or as determined by the ACCC through arbitration.
 
  It is expected that in many areas, the industry will negotiate, on a
multilateral basis, standard terms and conditions for access to declared
services. 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.
 
  Carrier license conditions will include an obligation to provide other
carriers with access to certain facilities and network information. A carrier
must provide other carriers with access to its facilities for the purpose of
enabling the other carriers to provide competitive facilities and competitive
carriage services or to establish their own facilities; to certain information
relating to the operation of its telecommunications network; and to its
infrastructure, including transmission towers, the sites of transmission
towers and underground facilities that are designed to hold lines, if
technically feasible.
 
  In July 1997, the Australian government mandated that Telstra provide access
to its facilities at specified rates to other service providers including the
Company. The Company is negotiating various access arrangements with Telstra
which will be substituted for the mandated arrangements.
 
  Foreign Ownership Limitations. Foreign investment in Australia is regulated
by the Foreign Acquisitions and Takeovers Act 1975. Administration of the
Australian Government's policy on foreign investment is based on guidelines
published in 1992 providing for notification of proposals for the
establishment of new businesses involving total investment of at least A$10
million and proposals for the acquisition of existing business with total
assets valued at more than A$5 million. The Company notified the Australian
Government of its proposed acquisition of Axicorp in 1996 and was 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 the Company,
in the future.

 Japan
 
  The Company's services in Japan are or will be subject to regulation by the
Japanese Telecom Ministry under the Japanese Telecom Law. The Company has
obtained a license as a Special Type II business, which allows it 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. The Company may also provide over leased
lines basic telecommunications services, value-added services and services to
closed user groups. The Company is preparing to apply for a license to operate
as a Type I business, which would allow the Company to provide
telecommunications services using their own facilities. The Company only must
notify the Japanese Telecom Ministry as a General Type II business if it
provides domestic service in Japan over leased circuits and does not exceed
the traffic threshhold applicable to Special Type II businesses. Although the
Japanese government until recently prohibited greater than 33% foreign
ownership of a Type I business, as well as the resale of international private
lines interconnected to the public switched network at both ends, the Japanese
Telecom Ministry recently has begun awarding authorizations to foreign-
affiliated carriers to provide telecommunications services using their own
facilities and to resell interconnected international private lines. The
Japanese Telecom Ministry also regulates the interconnection charges imposed
by Type I businesses, and must approve intercarrier agreements between Type I
carriers or between Type I and Special Type II carriers.
 
 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 (the "EU"), which is responsible for creating pan-
European policies and, through legislation, developing a regulatory framework
to ensure an open, competitive telecommunications market.
 
  In 1990, the European Commission issued the Services Directive requiring
each EU member state to abolish existing monopolies in telecommunications
services with the exception of real time two-way voice telephony to
the public, which was still reserved to the PTT. The intended effect of the
Services Directive was to permit the competitive provision of all services,
including value-added services and voice services to closed user groups
("CUG"), other than such reserved public voice telephony services. However, as
a consequence of local implementation of the Services Directive through the
adoption of national legislation, there are differing interpretations of the
definition of such reserved voice telephony services and permitted value-added
and CUG services. Other voice services accessed by customers through leased
lines were permissible in all EU member states. The European Commission has
generally taken a narrow view of the services classified as reserved voice
telephony, declaring that voice services may not be reserved to the PTTs if
(i) dedicated customer access is used to provide the service, (ii) the service
essentially consists of new value-added benefits on users (such as alternative
billing methods) or (iii) calling is limited by a service provider to a group
having legal, economic or professional ties.
 
  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 PTTs' monopolies
in voice telephony by 1998. To date, Denmark, Finland, the Netherlands,
Sweden, Germany, France, Austria and the U.K. have liberalized facilities-
based competition. Certain EU countries may 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 (November
30, 1998), Ireland (December 31, 1998), Portugal (January 1, 2000) and Greece
(December 31, 2000).
 
  Each EU member state in which the Company currently conducts or plans to
conduct its business has a different regulatory regime and such differences
have continued beyond January 1998. The requirements for the Company to obtain
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
 
                                      80
<PAGE>
 
EU generally does not permit its member states to require individual licenses
for other types of services. In addition, the Company has 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, the Company may be delayed in obtaining or may not be able to
obtain interconnection in certain countries that would allow the Company to
compete effectively. Moreover, there can be no guarantee that long distance
providers such as the Company will be able to afford their 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 PTTs.
 
 United Kingdom
 
  The Company's 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 (the
"DTI"), is responsible for granting UK telecommunications licenses, while the
Director General of Telecommunications (the "Director General") 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
anticompetitive behavior.
 
  In 1991, the British government established a "multi-operator" policy to
replace the duopoly that had existed between British Telecom and Mercury.
Under the multi-operator policy, the DTI recommends the grant of a license to
operate a telecommunications network to any applicant that the DTI 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 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. 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).
 
  The Company's subsidiary, Primus Telecommunications Limited, holds an ISVR
license that authorizes it to provide switched voice services over leased
private lines to all international points. In addition, the Company's
subsidiary, 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 the Company 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.
 
  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 greater pricing flexibility, including flexibility
for pricing toll free and other services. Greater pricing flexibility could
allow British Telecom to charge the Company higher prices for certain services
or to charge end user customers prices that are lower than the Company is able
to charge.
 
  Interconnection and Indirect Access. The Company must interconnect its U.K.
network to networks of other service providers in the United Kingdom and allow
its end user customers to obtain access to its services in order to compete
effectively in the United Kingdom. In the United Kingdom, licensed long
distance carriers such as the Company can obtain interconnection to British
Telecom at cost-based rates. However, while
 
                                      81
<PAGE>
 
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. Oftel's limited
authority in this area is derived from the powers given to Oftel under the
United Kingdom Telecommunications Act and from the terms of the licenses
granted under the United Kingdom Telecommunications Act. Any dispute between
Oftel and a telecommunications service provider may be referred on appeal to
the United Kingdom Monopolies and Mergers Commission, which may conduct a
detailed and lengthy review of the facts surrounding such dispute. At present,
Oftel has no authority to impose fines for a breach of the terms of a license
issued under the United Kingdom Telecommunications Act, and third parties have
no right to damages for a past breach. Oftel has expressed its view that the
current regulatory regime is both obscure and uncertain. Oftel has, however,
been successful in its efforts to introduce a general competition provision
into British Telecom's license and those of all other Telecommunications Act
licensees modeled on European law so as to better police any potential
anticompetitive conduct harmful to the Company. The Fair Trading condition is
already incorporated in all international facilities-based licenses and has
been incorporated in all international simple voice resale licenses beginning
in July 1997. There are no foreign ownership restrictions that apply to
telecommunications company licensing in the United Kingdom although the DTI
does have a discretion as to whether to award licenses on a case by case
basis. The Company is also subject to general European law, which, among other
things, prohibits certain Anticompetitive agreements and abuses of dominant
market positions through Articles 85 and 86 of the Treaty of Rome. The
European Commission is entrusted with the principal enforcement powers under
European Union competition law. It has the power to impose fines of up to 10%
of a group's annual revenue in respect of breaches of Articles 85 and 86. In
most cases notification of potentially infringing agreements to the Commission
under Article 85 with a request for an exemption protects against the risk of
fines from the date of notification.
 
 Germany
 
  The German Telecom Act liberalized all telecommunications activities, except
for the voice telephony monopoly which was abolished on January 1, 1998. The
German Telecom Act has been complemented by several ordinances. The most
significant ordinances concern network access, rate regulation, universal
service, frequencies and customer protection.
 
  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. value-added, data,
etc.) are only subject to a notification requirement.
 
  The Regulierungsbehorde fur Telekommunikation und Post ("RegTP") has granted
the Company a class 4 license which, according to RegTP's current reading of
the German Telecom Act, gives Primus the ability to originate and terminate
calls throughout Germany. However, the RegTP may reinterpret the German
Telecom Act with regard to license requirements for Germany-wide origination
and termination. If that occurs the Company may have to extend its licenses
and may incur additional license fees.
 
  Companies that desire to connect with Deutsche Telekom's network must enter
into an interconnection agreement which specifies certain interconnection
tariffs. Changes in German regulatory policy may require network providers
requesting the lowest available interconnection tariffs from Deutsche Telekom
to either substantially invest in network technology (i.e. by installing more
points of interconnection) or pay higher prices. If a provider does not agree
with the tariff rates offered by Deutsche Telekom, the provider can take the
case to
 
                                      82
<PAGE>
 
the RegTP which determines the applicable rates. Since the Company is not a
dominant carrier, it is not subject to the same interconnection obligations
toward third parties.
 
  Several complaints, the outcome of which may affect the Company's business,
are currently pending before the 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
valid for all interconnected and licensed carriers for as long as the 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.
 
  The Company has entered into an interconnection agreement with Deutsche
Telekom at the regulated standard interconnection rates presently under court
review. The Company's 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, a party's license situation or those which are
considered by both parties to materially affect the interconnection agreement
in any other way. In addition, Deutsche Telekom has the right under the
agreement to apply to the RegTP for a ruling regarding (i) whether the
Company's German network structure, in particular the number and locations of
points of interconnection with Deutsche Telekom, entitles the Company to
interconnection as defined by Section 35 of the German Telekom Act and
(ii) whether the structure entitles the Company to the switching of calls
originating Germany-wide. If Deutsche Telekom requests such a ruling, the
interconnection agreement will have to be amended to reflect this ruling.
Deutsche Telekom has informed the Company by letter dated May 29, 1998 that it
will request such a ruling from the RegTP in accordance with the
interconnection agreement. The request is presently being reviewed by the
RegTp. An unfavorable decision by the RegTP overturning its current policy
could potentially adversely affect the Company's German business by requiring
additional investments into points of interconnection or switching facilities,
the payment of higher connection prices or a geographic restriction on the
switching of calls.
 
  The Company is 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. The Company may also 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,
Primus could be subject to such universal service requirements and financing
schemes if the Company has a market share in Germany of at least 4%.
 
 Latin America
 
  Various countries in Latin America have taken initial steps towards
deregulation in 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 PTT. In the last few years,
several Latin American countries have completely or partially privatized their
national carriers, including Argentina, Chile, Mexico, Peru and Venezuela. In
addition, certain countries have partially or completely opened 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 (PCS). Brazil currently is in the process of opening
its telecommunications market to competition. Brazil intends to privatize
Telecomunicacoes Brasileras S.A. ("Telebras"), which, through its 28 regional
subsidiaries, hold 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,
 
                                      83
<PAGE>
 
Columbia has recently 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--Empresas de
Telecomunicaciones 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 recently
opened basic telephony, and is currently auctioning radioelectric spectrum
frequencies for the provision of PCS and LMDS. Value-added services are also
fully open to competition in Mexico. Finally, in the Central American region,
Guatemala and El Salvador have recently 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
fully opened their markets to competition.

  The Company has never experienced a work stoppage, and none of the Company's
employees, including the employees of TresCom, are represented by a labor
union or covered by a collective bargaining agreement. The Company considers
its employee relations to be excellent.
 
PROPERTIES
 
  The Company currently leases its corporate headquarters which is located in
McLean, Virginia. Additionally, the Company also leases administrative,
technical and sales office space in Washington, D.C., the New York City
metropolitan area, Los Angeles and Tampa in the United States; Melbourne,
Sydney, Brisbane, Perth and Adelaide in Australia; London in the United
Kingdom; Vancouver, Toronto and Montreal in Canada; Tokyo in Japan; Mexico
City in Mexico; and Frankfurt in Germany. Total leased space approximates
130,000 square feet and the total annual lease costs are approximately $2.9
million. The operating leases expire at various times through 2006.
 
  TresCom leases all of its facilities, including its administrative and sales
offices, and its switch locations. TresCom's headquarters in Fort Lauderdale,
Florida consist of approximately 20,600 square feet of office space under
leases that expire through April 2003. In addition, TresCom leases an
aggregate of approximately 70,000 square feet where it maintains its sales
offices or switches.
 
  Certain communications equipment which includes network switches and
transmission lines are leased through operating and capital leases.
 
  Management believes that the Company's present administrative and sales
office facilities are adequate for its anticipated operations and that similar
space can readily be obtained as needed. The Company believes the current
leased facilities to house existing communications equipment are adequate.
However, as the Company's Network of switches grows, the Company expects to
lease additional locations to house the new equipment.
 
LEGAL PROCEEDINGS
 
  The Company is from time to time involved in litigation incidental to the
conduct of its business. The Company believes the outcome of pending legal
proceedings to which the Company is a party will not have a material adverse
effect on the Company's business, financial condition, results of operations,
or cash flows.

the 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 the Company's 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
 
                                      86
<PAGE>
 
three-year terms and approximately one-third of the directors sit for election
at each annual meeting of the Company's stockholders. A classified board of
directors may have the effect of deterring or delaying any attempt by any
group to obtain control of the Company 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
 
  During 1997, Primus paid each director $500 for each Primus Board meeting
and each Primus Committee meeting attended by such director in person.
Commencing with 1998, Primus pays directors an annual fee of $10,000 and will
reimburse their expenses for attending meetings, but has discontinued paying
any meeting fees. In addition, Primus grants each person who becomes an
Eligible Director (as defined in the Director Option Plan) options to purchase
15,000 shares of the Common Stock pursuant to Primus's Director Option Plan
which vest one-third upon the grant date, and one-third on each of the first
and second anniversary of the grant dates. Primus did not grant any such
options in 1997.
 
COMMITTEES OF THE BOARD
 
  The Company's 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 the Company's books, records and
financial statements and to review the Company's systems of accounting
(including its 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 the Company's 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
the Company's 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 the Company's management bonus plan.
 
COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
  The Compensation Committee of the Primus 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.

  There were no options exercised by Primus's Chief Executive Officer or the
Named Executive Officers during the year ended December 31, 1997.
 
STOCK PLANS
 
  Employee Stock Option Plan. The Company established the Employee Stock
Option Plan for its employees and consultants on January 2, 1995. Recently,
the 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 the Company and its Subsidiaries who
contribute to the development and success of the Company 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 Common Stock for which
options may be granted pursuant to the Employee Stock Option Plan is
3,690,500, of which 917,522 are available for future grants, subject to
certain adjustments reflecting changes in the Company's 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 the Board which is
comprised of directors who are not also employees of the Company. 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, 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. Board
members administering the Employee Stock Option Plan may vote on any matters
affecting the administration of the Plan, except that no member may act upon
the granting of an option to himself or herself.
 
 
                                      89
<PAGE>
 
  The exercise price of the options granted under the Employee Stock Option
Plan is determined by the Board of Directors, but may not be less than the
fair market value per share of the 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 the company's capital stock, then the exercise
price for such ISO may not be less than 110% of the fair market value per
share of the Common Stock on the date the option is granted. The Board of
Directors also determines the method of payment for the exercise of options
under the Employee Stock Option Plan, and may consist entirely of cash, check,
promissory notes or Common Stock having a fair market value on the date of
surrender equal to the aggregate exercise price. The 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 with, or
a consultant's engagement by, the Company 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 the Board
of Directors makes a determination that a terminated employee or consultant
engaged in disloyalty to the Company, 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 a competitor of the Company
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 the Company 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 the Company's stock, the approval by the
Company's stockholders of a merger, reorganization or consolidation of the
Company in which the Company's stockholders do not own 50% or more of the
voting power of the stock of the entity surviving such a transaction, the
approval of the Company's stockholders of an agreement of sale of all or
substantially all of the Company's assets, and the acceptance by the Company's
stockholders of a share exchange in which the Company's 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 the Company 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"),
the Company 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
the Company if an ISO lapses before exercise or is forfeited. The grant of a
NQSO has no immediate tax consequences to the Company. Upon the exercise of a
NQSO by an employee or consultant, the Company is 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 the Company if a NQSO lapses before exercise
or is forfeited.
 
  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 the Common Stock received on the exercise of the
ISO ("ISO Stock") is an adjustment for purposes of the alternative minimum
tax. Upon the exercise of an ISO, an employee will have a basis in the ISO
Stock received equal to the amount paid. An employee will be subject to
capital gain or loss upon the sale of ISO 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 ISO Stock was
 
                                      90
<PAGE>
 
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 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 the Company's Common Stock. If the
employee pays with shares of the Company's Common Stock that are already
owned, the basis of the newly acquired ISO 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 ("non-ISO Stock"), the transaction will be tax-free to the extent that the
number of shares received does not exceed the number of shares of non-ISO
Stock paid. The basis of the number of shares of newly acquired ISO Stock
which does not exceed the number of shares of non-ISO 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 non-ISO Stock
paid. To the extent that the employee receives more new shares than shares
surrendered, the "excess" shares of ISO Stock will take a zero basis. If an
employee exercises an ISO by using stock that is previously acquired ISO
Stock, however, certain special rules apply. If the employee has not held the
previously acquired ISO 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 ISO Stock, the use of such ISO Stock to pay the exercise
price will constitute a Disqualifying Disposition and subject the employee to
income tax with respect to the ISO Stock as described above. In such
circumstances, the basis of the newly acquired ISO Stock will be equal to the
fair market value of the previously acquired ISO 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. The Company
is 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
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 ISO Stock 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.
 
  The 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
 
                                      91
<PAGE>
 
designation of employees eligible thereunder, or decrease the price at which
options may be granted. The Board 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, the Company assumed a stock option plan previously sponsored by
TresCom. Pursuant to the terms of the TresCom Merger Agreement, each
outstanding option to acquire one share of TresCom common stock was converted
into an option to acquire 0.6147 shares of Company Common Stock. As assumed by
the Company, options to acquire 374,361 shares of Company Common Stock are
outstanding under this stock option plan (the "Primus- TresCom Option Plan").
The Primus-TresCom Option Plan provides for an equitable adjustment in the
number and price of shares of Common Stock with respect to outstanding Options
in the event the outstanding shares of 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 employes, consultants and directors of
TresCom prior to the TresCom Merger in order to increase their proprietary
interest in the success of the Company and to encourage them to continue to
provide services to the Company. No additional stock options will be granted
under the Primus-TresCom Option Plan.
 
  The Primus-TresCom Option Plan is administered by the board of directors of
the Company or by a committee appointed by the board of directors and
consisting of not less than two members of the board of directors who are not
also employees of the Company or any of its subsidiaries (the "Committee").
The Primus-TresCom Option Plan does not limit the length of time a director
may serve as part of the Committee. Subject to the terms of the Primus-TresCom
Option Plan, the board of directors or the 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 Common Stock purchased under an Option must be
made in full upon exercise of the Option, by certified or bank cashier's check
payable to the order of the Company or by any other means acceptable to the
Company, including, without limitation, tender of shares of 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 Common Stock
subject to the Option and includes other terms and conditions applicable to
the Option. 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.
 
  All Options issued under the Primus-TresCom Option Plan are entirely vested
and exercisable in full.
 
  The tax consequences to the Company and the recipient of the Option upon the
grant and exercise of either a NQSO or ISO, and the sale of 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. The Company 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 the Company by outside directors
(present or future incumbent directors who are not affiliated with or
employees of the Company or any subsidiary and who have not been nominated to
serve as directors pursuant to an agreement with the Company) whose services
are considered essential to the Company's 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 Common Stock for which options may be granted pursuant to the
Director Stock Option
 
                                      92
<PAGE>
 
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 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 the Board, upon the death or permanent
disability of a director, or if the Company merges with another Company and is
not the surviving corporation, the Company enters into an agreement to sell or
otherwise dispose of all or substantially all of its assets, or any person or
group acquires more than 20% of the Company's 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 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 the Company. Upon
the exercise of a NQSO by a director, the Company is 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 the Company 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 Common Stock acquired upon exercise thereof, are identical to
those described for NQSOs under "--Employee Stock Option Plan" above, except
that the Company has no withholding obligations upon the exercise of a NQSO by
a director.
 
  Employee Stock Purchase Plan. During 1997, the Board adopted and the
stockholders approved an Employee Stock Purchase Plan (the "ESP Plan"). The
ESP Plan provides employees with the right to purchase shares of Common Stock
through payroll deduction. A total of 2,000,000 shares of Common Stock are
available for purchase under the ESP Plan, subject to adjustment in the number
and price of shares of Common Stock available for purchase in the event the
outstanding shares of Common Stock are increased or decreased through stock
dividends, recapitalizations, reorganizations or similar changes. The Plan is
to be administered by the Board, which may delegate responsibility for such
administration to a committee of the Board (the "Committee"). Subject to the
terms of the ESP Plan, the Board 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 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 employees of the Company 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 Common Stock under the ESP Plan, would own five percent or
more of the total combined voting power or value of all classes of stock of
the Company or 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.
 
 
                                      93
<PAGE>
 
  Eligible employees may elect to participate in the ESP Plan during an
offering which starts on the first day of each month beginning on or after
adoption of the ESP Plan by the Board ("Offering Commencement Date") and ends
on the last day of each month ("Offering Termination Date"). Shares will be
deemed to have been purchased on the Offering Termination Date. The purchase
price per share offered under the ESP Plan will be 85 percent of the lesser
of: (1) the fair market value per share on the Offering Commencement Date, 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 Offering Termination Date, 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 ESP Plan shall file an
election form with the Board or Committee at least 15 days before the Offering
Commencement Date for the first offering for which such election form is
effective, on which he 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 Common Stock for which purchase rights are
exercised on any Offering Termination Date exceeds the maximum number of
shares of Common Stock available, the Board or 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 Offering Termination Date.
 
  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 the Board or Committee on
or before the 15th day of the month immediately preceding the Offering
Commencement Date for the offering 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 the Board or the
Committee at any time before the Offering Termination Date 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 the Company under the ESP Plan may be used for
any corporate purpose until applied to the purchase of shares of Common Stock
or refunded to employees and shall not be segregated from the general assets
of the Company. Shares of Common Stock purchased under the ESP Plan will be
issued from the Company's treasury stock or from the Company's 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.
 
                                      94
<PAGE>
 
  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 Common Stock have been issued under the ESP
Plan, such shares may be assigned or transferred the same as any other shares.
 
  The Plan is not qualified under Section 401(a) of the Internal Revenue Code.
The Company 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 the Common Stock is purchased by the employee, or less than two
years after each Offering Commencement Date.
 
  Generally, no tax consequences arise at the time the participant purchases
shares of Common Stock. If a participant does not dispose of shares of 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 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.
 
  The Board or the 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.
 
EMPLOYMENT AGREEMENTS
 
  K. Paul Singh. Primus has entered into an employment agreement with Mr.
Singh (the "Singh Agreement"). 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. Under the terms of the Singh
Agreement, Mr. Singh is required to devote his full time efforts to Primus as
Chairman of the Board, President and Chief Financial Officer. Primus is
required to compensate Mr. Singh at an annual rate of $250,000 effective
January 1, 1997 (which amount is reviewed annually by the Primus Board 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. Primus is also obligated to (i)
allow Mr. Singh to participate in any bonus or incentive compensation plan
approved for senior management of Primus, (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.
 
  Primus may terminate the Singh Agreement at any time in the event of his
disability or for cause, each as defined in the Singh Agreement. Mr. Singh may
resign from Primus at any time without penalty (other than the non-competition
obligations discussed below). If Primus terminates the Singh Agreement for
disability or cause, Primus will have no further obligations to Mr. Singh. If,
however, Primus terminates the Singh Agreement other than for disability or
cause, Primus will have the following obligations: (i) if the termination is
after May 30,
 
                                      95
<PAGE>
 
1999, Primus must pay Mr. Singh one-twelfth of his then applicable base salary
as severance pay; and (ii) if the termination is before June 1, 1999, Primus
must pay to Mr. Singh, as they become due, all amounts otherwise payable if he
had remained employed by Primus until June 1, 1999. If Mr. Singh resigns, he
may not directly or indirectly compete with Primus's business until six months
after his resignation. If Primus terminates Mr. Singh's employment for any
reason, Mr. Singh may not directly or indirectly compete with Primus's
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 (the "O'Brien Agreement") which was amended and restated on
February 15, 1997 and was further amended on February 3, 1998. The O'Brien
Agreement was to terminate in June 1999 (the "Term"); however, it was
terminated by Mr. O'Brien for "Good Reason" (as such term is defined in the
O'Brien Agreement) as of June 22, 1998. Mr. O'Brien was required to devote his
full time efforts to TresCom as its President and Chief Executive Officer for
which he received an annual base salary of $231,000.
 
  Pursuant to the terms of the O'Brien Agreement, Mr. O'Brien will receive any
unpaid salary and bonus, as well as an additional amount equal to the salary
remaining for the balance of the Term of the O'Brien Agreement. 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 "O'Brien Special Bonus"). The first
installment of the O'Brien Special Bonus was paid contemporaneously with the
closing of the TresCom Merger, with the remainder paid upon Mr. O'Brien's
termination.
 
  Other Agreements. TresCom has also entered into agreements with Mr. Dan
O'Connor and Ms. Denise Boerger, (the "O'Connor/Boerger Agreements"). 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
recently completed 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 the Company.

                             CERTAIN TRANSACTIONS
 
PRIVATE EQUITY SALE
 
  In July 1996, Primus completed the sale of 965,999 shares of Common Stock to
the (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 (collectively, the "Soros/Chatterjee Group"), for an
aggregate purchase price of approximately $8.0 million. The Soros/Chatterjee
Group also purchased, for an additional $8.0 million, the right to receive,
upon exercise, an indeterminate number of shares of 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 Common Stock (the "Soros/Chatterjee Warrants"). The
Soros/Chatterjee Warrants have been exercised in full.
 
  The Soros/Chatterjee Group was granted registration rights pursuant to a
registration rights agreement with the Company (the "Registration Rights
Agreement"). 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 Common Stock
after the first demand registration. The Company is not required to effect any
demand registration within 180 days after the effective date of a previous

                      DESCRIPTION OF CERTAIN INDEBTEDNESS
 
1997 SENIOR NOTES
 
  General. The 1997 Senior Notes are senior obligations of the Company,
limited to $225 million in principal amount, and 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 Notes will rank senior in right of payment to any future
subordinated Indebtedness (as defined in the 1997 Indenture) of the Company,
and pari passu in right of payment with all senior indebtedness of the
Company. Because the Company is a holding company that conducts its business
through its subsidiaries, all existing and future indebtedness and other
liabilities and commitments of the Company's subsidiaries, including trade
payables, will be effectively senior to the 1997 Senior Notes.
 
  Security. The Indenture required the Company 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 (the "Pledged Securities"). The
Company used approximately $71.8 million of the net proceeds of the 1997
Senior Notes to acquire the 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 the option of the Company, 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>
<CAPTION>
            YEAR                   REDEMPTION PRICE
            ----                   ----------------
            <S>                    <C>
            2001                       105.875%
            2002                       102.938%
            2003 (and thereafter)      100.000%
</TABLE>
 
  In addition, prior to August 1, 2000, the Company 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 the Company 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 the ability of the Company and its 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, enter into certain transactions with affiliates, sell assets,
issue or sell Capital Stock of the Company's Restricted Subsidiaries or enter
into certain mergers and consolidations.
 
  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

one or more occasions redeem up to 25% of the originally issued principal
amount of Notes at a redemption price of 109.875% of the principal amount
thereof, plus accrued and unpaid interest thereon to the redemption date, with
the Net Cash Proceeds of one or more Public Equity Offerings; provided (i)
that at least 75% 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. (Sections 203 and 1103)
 
  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 existing and future obligations of the Company expressly subordinated
in right of payment to the Notes and will be pari passu in right of payment
with all other existing and future senior unsecured obligations of the Company
including trade payables. As of March 31, 1998, after giving pro forma effect
to the offering of the Initial Notes and the application of the net proceeds
thereof, the Company (on a consolidated basis) would have had outstanding
approximately $382.2 million of indebtedness ($387.6 million after giving
effect to the TresCom Merger). Because the Company is a holding company that
conducts its business through its subsidiaries, all existing and future
indebtedness and other liabilities and commitments of the Company's
subsidiaries, including trade payables, will be effectively senior to the
Notes. As of March 31, 1998, the Company's consolidated subsidiaries had
aggregate liabilities of approximately $101.0 million ($132.4 million after
giving effect to the TresCom Merger), which includes $9.5 million of
indebtedness ($14.9 million after giving effect to the TresCom Merger).
 
COVENANTS
 
 Limitation on Indebtedness
 
  (a) The Company will not, and will not permit any of its Restricted
Subsidiaries to, Incur any Indebtedness (other than the Notes); provided,
however, that the Company 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 the Company 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
 
                                      104
<PAGE>
 
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, the Company 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 the Company 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 and (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 the Company 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 the Company
(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 of such equipment, ownership rights or minimum
investment units so acquired); (iii) Indebtedness of any Restricted Subsidiary
to the Company or Indebtedness of the Company 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 the Company or
another Restricted Subsidiary) shall be deemed, in each case, to constitute
the incurrence of such Indebtedness, and provided further that Indebtedness of
the Company to a Restricted Subsidiary must be subordinated in right of
payment to the Notes; (iv) Indebtedness of the Company or a Restricted
Subsidiary issued in exchange for, or the net proceeds of which are used to
refinance or refund, then outstanding Indebtedness of the Company 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, (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 Indebtedness of the Company be refinanced by means of any
Indebtedness of any Restricted Subsidiary pursuant to this clause (iv);
(v) Indebtedness of the Company not to exceed, at any one time outstanding,
2.00 times (A) the Net Cash Proceeds received by the Company after the Closing
Date from the issuance and sale of its Common Stock (other than Redeemable
Stock) to a Person that is not a Subsidiary of the Company, to the extent such
Net Cash Proceeds have not been used pursuant to clause (C)(2) of the first
paragraph or clauses (iii), (iv) and (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 the 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 the Company after the Closing Date from the
issuance or sale of its Common Stock (other than Redeemable Stock) to a Person
that is not a Subsidiary of the Company to the extent such sale of Common
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
 
                                      105
<PAGE>
 
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 the Company 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
the Company 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 obligations of the Company or any of its
Restricted Subsidiaries pursuant to such agreements, in any case Incurred in
connection with the disposition of any business, assets or Restricted
Subsidiary of the Company (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 the Company or
any Restricted Subsidiary in connection with such disposition; (vii)
Indebtedness of the Company, 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
of the Company permitted by and made in accordance with the "Limitation on
Issuances of Guarantees of Indebtedness by Restricted Subsidiaries" covenant;
(ix) Indebtedness of the Company or any Restricted Subsidiary not otherwise
permitted hereunder in an aggregate principal amount, 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 the Company 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 the Company 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, the
Company, in its 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
 
  The Company 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 the Company's Capital Stock to the holders thereof
(other than dividends or distributions payable solely in shares of Capital
Stock (other than Redeemable Stock) of the Company 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 the Company 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 of the Company (including options, warrants or other rights to acquire
such shares of Capital Stock) held by any Person or any shares of Capital
Stock of any
 
                                      106
<PAGE>
 
Restricted Subsidiary (including options, warrants and other rights to acquire
such shares of Capital Stock) held by any Affiliate of the Company (other than
a Wholly Owned Restricted Subsidiary) or any holder (or any Affiliate thereof)
of 5% or more of the Company's Capital Stock, (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:
 
    (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 the
  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 the Company 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
  (b) 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 the Company after the Closing Date from the issuance and sale
  of its Capital Stock (other than Redeemable Stock) to a Person who is not a
  Subsidiary of the Company (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 date of the Indenture by the
  Company from the issuance or sale of debt securities that have been
  converted into or exchanged for Capital Stock of the Company (other than
  Redeemable Stock) together with the aggregate cash received by the Company
  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 of the Company in
exchange for, or out of the proceeds of a substantially concurrent offering
of, shares of Capital Stock (other than Redeemable Stock) of the Company
(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 of the Company 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 the Capital
Stock of the Company (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 the property and
assets of the Company; (vi) cash payments in lieu of the issuance of
fractional shares issued in connection with the exercise of any Common Stock
warrants;
 
                                      107
<PAGE>
 
(vii) Investments in Permitted Businesses acquired in exchange for Common
Stock (other than Redeemable Stock) of the Company or the Net Cash Proceeds
from the issuance and sale of such Common 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 the Company has made the Change of
Control offer as provided in such covenant with respect to the Notes and has
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 a Restricted Payment referred to in clause (ii) thereof,
and an exchange of Capital Stock for Capital Stock, Indebtedness or an
Investment referred to in clause (iii), (iv) or (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. In
the event the proceeds of an issuance of Capital Stock of the Company are used
for the redemption, repurchase or other acquisition of the Notes or
Indebtedness that is pari passu with the Notes, then the Net Cash Proceeds of
such issuance shall be included in clause (C) of the first paragraph of this
"Limitation on Restricted Payments" covenant only to the extent such proceeds
are not used for such redemption, repurchase or other acquisition of
Indebtedness.
 
  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 the Company and its 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, the Company 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 the Company or any other Restricted
Subsidiary, (ii) pay any indebtedness owed to the Company or any other
Restricted Subsidiary, (iii) make loans or advances to the Company or any
other Restricted Subsidiary, or (iv) transfer any of its property or assets to
the Company or any other Restricted Subsidiary.
 
  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 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 the Company) and the Company
determines that any such encumbrance or restriction will not materially affect
the Company's 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 the
Company or any Restricted Subsidiary, existing at the time of such acquisition
and not incurred
 
                                      108
<PAGE>
 
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 property or assets of the Company or 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 property or assets of the Company or any Restricted Subsidiary in
any manner material to the Company 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
the Company 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 the Company or any of its Restricted
Subsidiaries that secure Indebtedness of the Company or any of its Restricted
Subsidiaries. (Section 1013)
 
 Limitation on the Issuance and Sale of Capital Stock of Restricted
Subsidiaries
 
  The Company 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 the Company 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 (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
 
  The Company 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 of the
Company or with any Affiliate of the Company or any Restricted Subsidiary,
unless (i) such transaction or series of transactions is on terms no less
favorable to the Company 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 the
Board of Directors of the Company, including the approval of a majority of the
independent, disinterested directors, and is evidenced by a resolution of the
Board of Directors of the Company, and (iii) if such transaction or series of
transactions involves aggregate consideration in excess of $25.0 million, then
the Company or such Restricted Subsidiary will deliver to the Trustee a
written opinion as to the fairness to the Company 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
 
                                      109
<PAGE>
 
deemed to be on terms no less favorable to the Company 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 the Board of
Directors of the Company, including a majority of the independent,
disinterested directors, and are evidenced by a resolution of the Board of
Directors of the Company.
 
  The foregoing limitation does not limit, and will not apply to (i) any
transaction between the Company and any of its Restricted Subsidiaries or
between Restricted Subsidiaries; (ii) the payment of reasonable and customary
regular fees to directors of the Company who are not employees of the Company;
(iii) any Restricted Payments not prohibited by the "Limitation on Restricted
Payments" covenant; (iv) transactions provided for in the Employment
Agreements as in effect on the Closing Date; and (v) loans and advances to
employees of the Company 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)
 
 Limitation on Liens
 
  Under the terms of the Indenture, the Company 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 its 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
 
  The Company will not, and will not permit any Restricted Subsidiary to, make
any Asset Sale unless (i) the Company 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 the 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.
 
  The Company 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 unsubordinated Indebtedness of the Company or Indebtedness
of any Restricted Subsidiary, in each case owing to a Person other than the
Company 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, the Company and its Restricted Subsidiaries existing on the date
of such investment (as determined in good faith by the 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, the Company 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").
 
                                      110
<PAGE>
 
  The Company 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 the
Company defaults 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" 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 Officers' 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. The
Company 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.
 
  The Company will comply with Rule 14e-1 under the Exchange Act 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
 
  The Company will not permit any Restricted Subsidiary, directly or
indirectly, to guarantee, assume or in any other manner become liable with
respect to any Indebtedness of the Company, 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 or
reimbursement, indemnity or subrogation or any other rights against the
Company or any other Restricted Subsidiary as a result of any payment by such
Restricted Subsidiary under its Guarantee.
 
 
                                      111
<PAGE>
 
  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 the Company, of all of the Company's 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
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
 
  The Company 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
 
  The Company will not make, and will not permit any of its 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
the Board of Directors of the Company (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
 
  The Company will file on a timely basis with the Commission, to the extent
such filings are accepted by the Commission and whether or not the Company has
a class of securities registered under the Exchange Act, the annual reports,
quarterly reports and other documents that the Company would be required to
file if it were subject to Section 13 or 15 of the Exchange Act. All such
annual reports and quarterly reports shall include the geographic segment
financial information currently disclosed by the Company in its public filings
with the Commission. The Company 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 the Company
files such reports and documents with the Commission or the date on which the
Company would be required to file such reports and documents if the Company
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 the Company's cost copies of such reports and
documents to any prospective holder promptly upon request. (Section 1009)
 
REPURCHASE OF NOTES UPON A CHANGE OF CONTROL
 
  Upon the occurrence of a Change of Control, each holder shall have the right
to require the Company 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").
 
  Within 30 days of the Change of Control, the Company 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 the
 
                                      112
<PAGE>
 
Company defaults 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, the Company 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 Officers' 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.
The Company 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.
 
  The Company will comply with Rule 14e-1 under the Exchange Act 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
the Company is required to repurchase the Notes under this "Repurchase of
Notes Upon a Change of Control" covenant. (Section 1010)
 
  If the Company is unable to repay all of its indebtedness that would
prohibit repurchase of the Notes or is unable to obtain the consents of the
holders of indebtedness, if any, of the Company outstanding at the time of a
Change of Control whose consent would be so required to permit the repurchase
of Notes, then the Company will have breached such covenant. This breach will
constitute an Event of Default under the Indenture if it continues for a
period of 30 consecutive days after written notice is given to the Company by
the Trustee or the holders of at least 25% in aggregate principal amount of
the Notes outstanding. In addition, the failure by the Company 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 the Company 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 securities of the Company which might be
outstanding at the time). The above covenant requiring the Company to
repurchase the Notes will, unless the consents referred to above are obtained,
require the Company 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
 
  The Company will not consolidate with, merge with or into, or sell, convey,
transfer, lease or otherwise dispose of all or substantially all of its
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 the Company and the Company will not permit any
of its Restricted Subsidiaries to enter into any such transaction
 
                                      113
<PAGE>
 
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 the properties and
assets of the Company or the Company and its Restricted Subsidiaries, taken as
a whole, to any other Person or Persons, unless: (i) the Company will be the
continuing Person, or the Person (if other than the Company) formed by such
consolidation or into which the Company is merged or that acquired or leased
such property and assets of the Company will be a corporation 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 the obligations of the Company
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 the Company, 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) the Company delivers to the Trustee an Officers'
Certificate (attaching the arithmetic computations to demonstrate compliance
with clause (iii)) and Opinion of Counsel stating that such consolidation,
merger or transfer and such 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 the Board of
Directors of the Company, whose determination shall be evidenced by a Board
Resolution, the principal purpose of such transaction is to change the state
of incorporation of the Company; 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 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 when the same
becomes due and payable at maturity, upon acceleration, redemption or
otherwise; (c) default in the payment of principal or interest on Notes

perform or comply with the provisions described under "Consolidation, Merger
and Sale of Assets"; (e) default in the performance of or breach of any other
covenant or agreement of the Company in the Indenture or under the Notes
(other than a default specified in clause (a), (b), (c) or (d) above) and such

notice 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 the Company or any Restricted Subsidiary having an outstanding
principal amount of $10.0 million or more in the aggregate for all such issues
of all such Persons, whether such Indebtedness now exists or shall hereafter
be 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 the Company 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 the Company or any of its 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
 
                                      114
<PAGE>
 
similar official of the Company or any of its Significant Subsidiaries or for
all or substantially all of the property and assets of the Company or any of
its Significant Subsidiaries or (C) the winding up or liquidation of the
affairs of the Company 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) the Company or any of its Significant Subsidiaries
(A) commences a voluntary case under any applicable bankruptcy, insolvency or
other similar law now or hereafter in effect, or consents 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 similar official of the Company or any of
its Significant Subsidiaries or for all or substantially all of the property
and assets of the Company 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 Notes, then
outstanding, by written notice to the Company (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 on the Notes to be immediately due and payable. Upon a
declaration of acceleration, such principal of, premium, if any, and accrued
interest 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 event of default triggering such
Event of Default pursuant to clause (f) shall be remedied or cured by the
Company and/or the relevant Significant Subsidiaries or waived by the holders
of the relevant Indebtedness within 60 days after the declaration of
acceleration with respect thereto. If an Event of Default specified in clause
(h) or (i) above occurs, the principal of, premium, if any, and accrued
interest 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 the Company and to the
Trustee, may waive all past defaults and rescind and annul a declaration of
acceleration and its consequences if (i) all existing Events of Default, other
than the nonpayment of the principal of, premium, if any, and accrued and
unpaid interest on the Notes that have become due solely by such declaration
of acceleration, have been cured or waived and (ii) the rescission would not
conflict with any judgment or decree of a court of competent jurisdiction. For
information as to the waiver of defaults, see "--Modification and Waiver."
(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 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 and 508)
 
  The Indenture will require certain officers of the Company to certify, on or
before a date not more than 120 days after the end of each fiscal year, that a
review has been conducted of the activities of the Company and the
 
                                      115
<PAGE>
 
Company's performance under the Indenture and that the Company has 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. The Company 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
 
  The Company may, at its option and at any time, elect to have the
obligations of the Company upon the Notes discharged with respect to the
outstanding Notes ("defeasance"). Such defeasance means that the Company will
be deemed to have paid and discharged the entire Indebtedness represented by
the outstanding Notes and to have satisfied all its 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 on such Notes when such payments are due, (ii) the Company's
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,
the Company may, at its option and at any time, elect to have the obligations
of the Company 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) the
Company 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 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 clause (x) 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 the Company is a party or by which it is bound; (iv)
in the case of defeasance, the Company shall have delivered to the Trustee an
Opinion of Counsel stating that the Company has received from, or there has
been published by, the Internal Revenue Service a ruling, or since May 14,
1998, 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, the Company 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) the Company 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)
 
MODIFICATION AND WAIVER
 
  Modifications and amendments of the Indenture may be made by the Company 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
 
                                      116
<PAGE>
 
the principal amount of, or premium, 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 place or 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) waive a default in the
payment of principal of, premium, if any, or accrued and unpaid interest on
the Notes or (vii) 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. The Company 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 the Company 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 the winding-up or dissolution of the Company or
otherwise) by any holder of a Note in respect of any sum expressed to be due
to it from the Company shall only constitute a discharge to the Company 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, the Company shall indemnify the recipient against
any loss sustained by it as a result. In any event, the Company 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 the Company's 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 the Issuers, 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
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
 
                                      117

or powers under the Indenture at the request of any holder of Notes, unless

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"
in reliance on Rule 144A and, to certain non-U.S. Holders, Regulation S under
the Securities Act. The Initial Notes were issued in registered, global form
in minimum denominations of $1,000 and integral multiples of $1,000 in excess
thereof.
 
  The Initial Notes are represented by one or more Notes in registered, global
form without interest coupons (the "Restricted Global Note"), and, except as
set forth below, the Exchange Notes will be represented by one or more Notes
in registered, global form without interest coupons (the "Unrestricted Global
Note," and together with the Restricted Global Note, the "Global Note"). The
Restricted Global Note was, and the Unrestricted Global Note will be,
deposited upon issuance with the Trustee as custodian for the Depository in
Richmond, Virginia 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 in the Depositary as described below.
 
  Except as set forth below, the Global Note may be transferred, in whole and
not in part, only to another nominee of The Depositary or to a successor of
the Depositary or its nominee. Beneficial interests in the Global Note may not
be exchanged for Notes in certificated form except in the limited
circumstances described below. See "Exchange of Book-Entry Notes for
Certificated Notes."
 
  The Trustee will act as Registrar.
 
DEPOSITARY PROCEDURES
 
  The Depositary has advised the Company 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 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 the Company that pursuant to procedures
established by it, (i) upon deposit of the Global Note, the Depositary will
credit the accounts of Participants designated by the Initial Purchasers with
portions of the principal amount of the Global Note and (ii) ownership of such
interests in the Global Note 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 Note).
 
  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. For certain
other restrictions on the transferability of the Notes, see "--Exchange of
Book-Entry Notes for Certificated Notes."
 
                                      127
<PAGE>
 
  EXCEPT AS DESCRIBED BELOW, OWNERS OF INTERESTS IN THE GLOBAL NOTE 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, the Company and the Trustee will
treat the persons in whose names the Notes, including the Global Note, are
registered as the owners thereof for the purpose of receiving such payments
and for any and all other purposes whatsoever. Consequently, neither the
Company, the Trustee nor any agent of the Company or the Trustee has 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 Note,
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 Note 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 the Company 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 Note 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 the Company. Neither the Company nor the Trustee will be liable for
any delay by the Depositary or its Participants in identifying the beneficial
owners of the Notes, and the Company and the Trustee may conclusively rely on
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 Note 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 the Company 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 Note
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 the Global Note 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 the Company believes to be
reliable, but the Company takes no responsibility for the accuracy thereof.
Neither the Company 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 the Company that it is
unwilling or unable to continue as depository for the Global Note and the
Company thereupon fails to appoint a successor depository or (B) has ceased to
be a clearing agency registered under the Exchange Act, (ii) upon the
continuance of an Event of Default or (iii) the Company, at its option,
 
                                      128
<PAGE>
 
notifies the Trustee in writing that it elects 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 the Company determines otherwise in compliance with
applicable law.
 
 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, the Company 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. The Company expects that secondary trading in the
certificated Notes will also be settled in immediately available funds.
 
REGISTRATION RIGHTS
 
  The holders of the Exchange Notes are not entitled to any registration
rights with respect to the Exchange Notes. The Company has entered into the
Registration Rights Agreement with the Initial Purchasers, pursuant to which
the Company agreed to file with the Commission, subject to the provisions
described below, the Exchange Offer Registration Statement on an appropriate
form permitting registration of the Exchange Notes to be offered in exchange
for the Transfer Restricted Securities and to permit resales of Exchange Notes
held by broker-dealers as contemplated by the Registration Rights Agreement.
The Registration Statement of which this Prospectus forms a part constitutes
the Exchange Offer Registration Statement.
 
  The Registration Rights Agreement provides that if (i) the Company is 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) the Exchange Offer is not for any other reason
consummated by October 16, 1998 or (iii) 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, the Company will use its reasonable best efforts to:
(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. The Company shall use its 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
the Company 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).
 
  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 Exchange Notes in the
Exchange Offer, (ii) following the exchange by a broker-dealer in the Exchange
Offer of such Note
 
                                      129
<PAGE>
 
for one or more Exchange Notes, the date on which such Exchange 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 and disposed of in accordance with the
Shelf Registration Statement or (iv) the date on which such Note is eligible
for distribution to the public pursuant to Rule 144 under the Securities Act.
 
  If (i) the Company fails 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 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 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 such event referred to in clauses (i)
through (iv) above, a "Registration Default"), 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 the
Company 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.
 
  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 is filed as an exhibit to the Registration
Statement of which this Prospectus constitutes a part, will be made available
to prospective purchasers of the Notes upon request to the Company.

                   CERTAIN FEDERAL INCOME TAX CONSIDERATIONS
 
  The following is a general discussion of certain material United States
federal income tax consequences of the purchase, ownership and disposition of
Notes by holders that acquire Notes at original issuance for cash at their
face value. This discussion is limited to holders who hold the Notes as
capital assets, within the meaning of Section 1221 of the Internal Revenue
Code of 1986, as amended (the "Code"). Furthermore, 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 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 herein, the term "U.S. Holder" means a holder of a Note that is, for
United States federal income tax purposes, (i) a citizen or resident of the
United States, (ii) a corporation or partnership created or organized under
the laws of the United States or of any political subdivision thereof, (iii)
an estate the income of which is subject to United States federal income
taxation regardless of its source or (iv) 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. The term "Non-U.S. Holder", means a
holder of a Note other than a U.S. Holder.
 
U.S. TAXATION OF U.S. HOLDERS
 
  Payments of Interest. Stated interest payable on the 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.
 
  Payments of Additional Interest/Redemption Premium. Because the Notes
provide for the payment of additional interest or redemption premium under
certain circumstances, the Notes may be subject to Treasury regulations
applicable to debt instruments that provide for one or more contingent
payments. Under such Treasury regulations, if the payment of such liquidated
damages is, as of the date the Notes are issued, either a "remote" or
"incidental" contingency, the payment would not be considered a contingent
payment and such amounts would be accounted for under the holder's normal
method of accounting for tax purposes. The Company intends, solely for these
purposes, to treat the possibility of the payment of such liquidated damages
as a remote or incidental contingency. Such determination is binding on a
holder unless such holder discloses to the Internal Revenue Service (the
"IRS") that it is taking a contrary position.
 
  Disposition of the Notes. Upon the sale, exchange, redemption, retirement at
maturity or other disposition of a Note (collectively, a "Disposition"), a
U.S. Holder generally will recognize capital gain or loss equal to the
difference between the amount realized by such U.S. Holder (except to the
extent such amount is attributable to accrued interest, which will be treated
as ordinary interest income) and such U.S. Holder's adjusted tax basis in the
Note. A holder's adjusted tax basis in the Notes will generally be equal to
the amount such holder paid for the Note. Such capital gain or loss generally
will be long-term capital gain or loss if the holding period for the Note
exceeds one year at the time of the Disposition. Generally, the maximum tax
rate for individuals on long term capital gain is 28% for capital assets held
for more than one year but for 18 months or less, and 20% for capital assets
held for more than 18 months.
 
                                      131
<PAGE>
 
  The exchange of an Initial Note for an Exchange Note will not be a taxable
event for a Holder.
 
U.S. TAXATION OF NON-U.S. HOLDERS
 
  Payments of Interest. In general, 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 (i) does not actually or constructively own 10% or
more of the total combined voting power of all classes of stock of the Company
entitled to vote, (ii) is not a controlled foreign corporation that is related
to the Company actually or constructively through stock ownership, and (iii)
either (x) the beneficial owner of the Note provides the Company or its paying
agent with a properly executed certification on IRS form W-8 (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 (y) a securities clearing
organization, bank or other financial institution that holds customer's
securities in the ordinary course of its business holds the Note and certifies
to the Company or its agent under penalties of perjury that the IRS form W-8
(or a suitable substitute form) has been received by it from the beneficial
owner of the 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 will be subject to such withholding tax at the rate of 30%,
unless reduced or eliminated under an applicable income tax treaty, and the
required documentation to claim the treaty benefit is provided.
 
  Treasury regulations that will be effective with respect to payments made
after December 31, 1999 (the "Withholding Regulations") provide alternative
methods for satisfying the certification requirements described in the
preceding paragraph. The Withholding Regulations also will require, in the
case of Notes held by a foreign partnership, that the certification described
above be provided by each partner.
 
  Disposition of the Notes. A Non-U.S. Holder generally will not be subject to
U.S. federal income tax (and generally no tax will be withheld) with respect
to gain realized on the Disposition of a Note, unless (i) the gain is
effectively connected with a U.S. trade or business conducted by the Non-U.S.
Holder or (ii) 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 requirements are satisfied.
 
  Effectively Connected Income. If interest and other payments received by a
Non-U.S. Holder with respect to the Notes (including proceeds from the
Disposition of the 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), such 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). Such Non-U.S. Holder may also be subject to the
U.S. "branch profits tax" if such holder is a corporation.
 
BACKUP WITHHOLDING AND INFORMATION REPORTING
 
  Certain non-corporate U.S. Holders may be subject to backup withholding at a
rate of 31% on payments of principal, premium and interest on, and the
proceeds of the Disposition of, the Notes. In general, backup withholding only
will be imposed on a U.S. Holder if he, she or it (i) fails to furnish a
taxpayer identification number ("TIN") which, for an individual, would be his
or her Social Security number, (ii) furnishes an incorrect TIN, (iii) is
notified by the IRS that he, she or it has failed to report payments of
interest or dividends or (iv) under certain circumstances, fails to certify,
under penalty of perjury, that he, she or it (a) has furnished a correct TIN
and (b) has not been notified by the IRS that he, she or it is subject to
backup withholding tax for failure to report interest or dividend payments.
 
  Backup withholding generally will not apply to payments made to a Non-U.S.
Holder of a Note 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 the payor does not have
actual knowledge that the holder is a U.S. person.

THE EXCHANGE OFFER
 
  The exchange of Initial Notes for Exchange Notes pursuant to the Exchange
Offer will not constitute a significant modification of the terms of the
Initial Notes and, therefore, such exchange will not constitute an exchange
for United States federal income tax purposes. Accordingly, such exchange will
have no United States federal income tax consequences to U.S. holders of the
Initial Notes and the holding period of the Exchange Notes will include the
holding period of the Initial Notes and the basis of the Exchange Notes will
be the same as the basis of the Initial Notes immediately before the exchange.
 
ORIGINAL ISSUE DISCOUNT AND STATED INTEREST
 
  The Initial Notes were issued and the Exchange Notes will be issued without
original issue discount. Stated interest on the Initial and Exchange Notes
will be taxable to a holder as ordinary interest income at the time it is
accrued or paid in accordance with such holder's method of accounting for tax
purposes.
 
BOND PREMIUM ON THE EXCHANGE NOTES
 
  If a holder of an Exchange Note purchased the Initial Notes for an amount in
excess of the amount payable at the maturity date (or a call date, if
appropriate) of the Initial Notes, the holder may deduct such excess as
amortizable bond premium over the aggregate terms of the Initial Notes and the
Exchange Notes (taking into account earlier call dates, as appropriate), under
a yield-to-maturity formula. The deduction is available only if an election is
made by the purchaser or is in effect. This election is revocable only with
the consent of the IRS. The election applies to all obligations owned or
subsequently acquired by the holder. The holder's adjusted tax basis in the
Initial Notes and the Exchange Notes will be reduced to the extent of the
deduction of amortizable bond premium. Except as may otherwise be provided in
future regulations, under the Code the amortizable bond premium is treated as
an offset to interest income on the Initial Notes and the Exchange Notes
rather than as a separate deduction item.
 
MARKET DISCOUNT ON THE EXCHANGE NOTES
 
  Tax consequences of a disposition of the Exchange Notes may be affected by
the market discount provisions of the Code. These rules generally provide that
if a holder acquired the Initial Notes (other than in an original issue) at a
market discount which equals or exceeds 1/4 of 1% of the stated redemption
price of the Initial Notes at maturity multiplied by the number of remaining
complete years to maturity and thereafter recognizes gain upon a disposition
(or makes a gift) of the Exchange Notes, the lesser of (i) such gain (or
appreciation, in the case of a gift) or (ii) the portion of the market
discount which accrued while the Initial or Exchange Notes were held by such
holder will be treated as ordinary income at the time of the disposition (or
gift). For these purposes, market discount means the excess (if any) of the
stated redemption price at maturity over the basis of such Initial or Exchange
Notes immediately after their acquisition by the holder. A holder of the
Exchange Notes may elect to include any market discount (whether accrued under
the Initial Notes or the Exchange Notes) in income currently rather than upon
disposition of the Exchange Notes. This election once made applies to all
market discount obligations acquired on or after the first taxable year to
which the election applies, and may not be revoked without the consent of the
IRS.
 
  A holder of any Exchange Note who acquired the Initial Note at a market
discount generally will be required to defer the deduction of a portion of the
interest on any indebtedness incurred or maintained to purchase or carry such
Initial or Exchange Note until the market discount is recognized upon a
subsequent disposition of such Exchange Note. Such a deferral is not required,
however if the holder elects to include accrued market discount in income
currently.
 
REDEMPTION OR SALE OF THE EXCHANGE NOTES
 
  Generally, any redemption or sale of the Exchange Notes by a holder should
result in taxable gain or loss equal to the difference between the amount of
cash and the fair market value of property received (except to the
 
                                      133
<PAGE>
 
extent that such cash or property received is attributable to accrued, but
previously untaxed, interest) and the holder's tax basis in the Exchange
Notes. The tax basis of a holder of the Exchange Notes should generally be
equal to the price paid for the Initial Notes exchanged therefor, plus any
accrued market discount on the Exchange Notes (and the Initial Notes exchanged
therefor) included in the holder's income prior to sale or redemption of the
Exchange Notes, or reduced by any amortizable bond premium applied against the
holder's income prior to sale or redemption of the Exchange Notes. Such gain
or loss generally would be long-term capital gain or loss if the holding
period exceeded one year, except to the extent it constitutes accrued market
discount.
 
  THE FOREGOING DISCUSSION OF CERTAIN FEDERAL INCOME TAX CONSEQUENCES IS FOR
GENERAL INFORMATION ONLY AND IS NOT TAX ADVICE. ACCORDINGLY, EACH HOLDER OF
THE INITIAL NOTES SHOULD CONSULT HIS OR HER TAX ADVISOR WITH RESPECT TO THE
TAX CONSEQUENCES TO HIM OR HER OF THE ACQUISITION, OWNERSHIP AND DISPOSITION
OF THE EXCHANGE NOTES, INCLUDING THE APPLICABILITY AND EFFECT OF STATE, LOCAL,
FOREIGN AND OTHER TAX LAWS.

                             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 the Company), may exchange Initial Notes
for Exchange 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 Exchange 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. The Company has agreed that, for a period of
180 days after the effective date of this Prospectus, it will make this
Prospectus, as amended or supplemented, available to any broker-dealer who
receives Exchange Notes in the Exchange Offer for use in connection with any
such sale. The Company will not receive any proceeds from any sales of
Exchange Notes by broker-dealers. Exchange 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 Exchange 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 Exchange 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 Exchange Notes. Any broker-dealer that resells Exchange
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
Exchange Notes may be deemed to be an "underwriter" within the meaning of the
Securities Act and any profit on any such resale of Exchange Notes and any
commissions or concessions received by any such persons may be deemed to be
underwriting compensation under the Securities Act. The Company has 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
Exchange Notes pursuant to the Exchange Offer hereby agrees to notify the
Company prior to using the Prospectus in connection with the sale or transfer
of Exchange Notes, and acknowledges and agrees that, upon receipt of notice
from the Company 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 the Company agrees to deliver promptly to such
broker-dealer), such broker-dealer will suspend use of the Prospectus until
the Company has 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.

                         INDEPENDENT AUDITORS' REPORT
 
To the Board of Directors 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, 1997 and 1996, and the related consolidated statements of
operations, stockholders' equity (deficit), and cash flows for each of the
three years in the period ended December 31, 1997. 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, 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.

                 PRIMUS TELECOMMUNICATIONS GROUP, INCORPORATED
 
                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1. ORGANIZATION AND BUSINESS
 
  Primus Telecommunications Group, Incorporated (the "Company") is a global
telecommunications company that focuses on the provision of international and
domestic long distance telecommunications services. Incorporated in Delaware
in February 1994, the Company's customers include small-and medium-sized
businesses, residential consumers and other telecommunication carriers,
primarily located in North America, Asia-Pacific, and Europe. The Company
operates as a holding company and has wholly-owned operating subsidiaries in
the United States, Canada, Mexico, Australia, Japan, Germany and the United
Kingdom. The Company intends to enter the Caribbean, and the Central and South
American markets with its pending acquisition of TresCom International, Inc.
("TresCom"). See Note 15 below.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Principles of Consolidation--The consolidated financial statements include
the accounts of the Company and its wholly-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 which 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 accumulated as a separate component of stockholders' equity. Foreign
currency transaction gains and losses are the primary components of Other
Income (Expense) in the consolidated statement of operations.
 
  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 reflected at amortized cost.
These securities are classified as held-to-maturity and are restricted to
satisfy certain interest obligations on the Company's senior notes.
 
  Short Term Investments--Highly liquid investments in United States Federal
Government-backed obligations with original maturities in excess of three
months are classified as available-for-sale and reported at fair value. Cost
approximates fair value for all components of short-term investments;
unrealized gains and losses are reflected in stockholders' equity and are not
material.
 
  Property and Equipment--Property and equipment, which consists of furniture
and computer equipment, leasehold improvements, software, fiber optic cable
and telecommunications equipment, is stated at cost less accumulated
depreciation and amortization. Expenditures for maintenance and repairs that
do not materially extend the useful lives of the assets are charged to
expense. Depreciation and amortization expense is 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, whichever is shorter.
 
  Intangible Assets--At December 31, 1997 and 1996 intangible assets, net of
accumulated amortization, consist of goodwill of $27,848,000 and $17,434,000,
respectively, and customer lists of $5,316,000 and $3,812,000, respectively.
Goodwill is being amortized over 30 years on a straight-line basis and
customer lists

                 PRIMUS TELECOMMUNICATIONS GROUP, INCORPORATED
 
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
over the estimated run-off of the customer bases not to exceed five years.
Accumulated amortization at December 31, 1997 and 1996, was $1,152,000 and
$498,000 related to goodwill and $1,939,000 and $762,000 related to customer
lists, respectively. The Company periodically evaluates the realizability of
intangible assets. In making such evaluations, the Company compares certain
financial indicators such as expected undiscounted future revenues and cash
flows to the carrying amount of the intangibles. The Company believes that no
impairments of intangible assets exist as of December 31, 1997.
 
  Deferred Financing Costs--Deferred financing costs incurred in connection
with the 1997 Senior Notes and Warrants Offering are reflected within other
assets on the balance sheet and are being amortized over the life of the
senior notes using the straight-line method, which does not differ materially
from the effective interest method.
 
  Stock-Based Compensation--In 1996, the Company adopted Statement of
Financial Accounting Standards No. 123 ("SFAS 123"), Accounting for Stock-
Based Compensation. Upon adoption 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 basic and diluted
net 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--During 1997, the Company adopted Statement of Financial
Accounting Standards (SFAS) No. 128, Earnings Per Share and 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,
after giving effect to stock splits (Note 9). 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.
 
  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 the Company's initial public offering
(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 SFAS 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.

  New Accounting Pronouncements--In 1998, the Company will be required to
adopt the provisions of Statement of Financial Accounting Standards (SFAS) No.
130, Reporting Comprehensive Income, and SFAS No. 131, Disclosures about
Segments of an Enterprise and Related Information. The Company will report
comprehensive income in a separate statement which will show the effects of
the foreign currency translation adjustment as a component of comprehensive
income. The Company believes its segment disclosures under SFAS No. 131 will
be consistent with those currently presented.
 
  Reclassifications--Certain prior year amounts have been reclassified to

3. ACQUISITIONS
 
  On October 20, 1997, the Company completed the acquisition of 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. The purchase price was allocated on a preliminary basis to the net
assets acquired based upon the estimated fair value of such net assets, which
resulted in an allocation of $7.75 million to goodwill.
 
  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 completed the acquisition of the outstanding
capital stock of Axicorp Pty., Ltd. ("Axicorp"), 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.
 
  The Company has accounted for all of the referenced acquisitions using the
purchase method. Accordingly, the results of operations of the acquired
companies are included in the consolidated results of operations of the
Company, as of the date of their respective acquisition.
 
  Pro forma operating results for the years ended December 31, 1997 and 1996,

1,771,194 shares of common stock to numerous investors. The Company also
issued 278,899 shares of common stock for services rendered in conjunction
with this offering.
 
  Also in January 1996, the Company entered into an agreement with Teleglobe
USA, Inc., under which it sold 410,808 shares of common stock for
approximately $1.4 million and borrowed $2.0 million (see Note 5).
 
  In December 1995, $359,000 was committed to the Company in exchange for
121,209 shares of the Company's common stock in conjunction with a private
placement. The shares were sold in December 1995 and the physical certificates
were issued in January 1996.
 
  Effective March 13, 1995, the Company's Certificate was amended to increase
the number of authorized shares of the Company's common stock from 1,000,000
shares to 5,000,000 shares and to split each share of common stock outstanding
on March 13, 1995, into 2.1126709 shares of common stock.
 
  All share amounts have been restated to give effect to the November 7, 1996
and the March 13, 1995 stock splits.
 
10. STOCK-BASED COMPENSATION
 
  The Company has established 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 no 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 has established a Director Stock Option Plan (the "Director
Plan") for nonemployee directors. Under the Director Plan, an option is
granted to each nonemployee director to purchase 50,715 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 years ended December 31, is as

  The weighted average fair value at date of grant for options granted during
1997, 1996 and 1995 was $5.45, $1.38 and $1.04 per option, respectively. The
fair value of the option grant is estimated on the date of grant using the
Black-Scholes option pricing model with the following assumptions:

11. EMPLOYEE BENEFIT PLANS
 
  The Company has a 401(k) employee benefit plan (the "401(k) Plan") that
covers substantially all United States based employees. The 401(k) Plan
provides that employees may contribute amounts not to exceed statutory
limitations. During 1997, the shareholders adopted 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 $45,000 during 1997.
 
  During 1997, the Company's shareholders approved the adoption of 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. The Plan commenced on January 1, 1998.
An aggregate of 2,000,000 shares of common stock were reserved for issuance
under the ESPP.

15. SUBSEQUENT EVENTS
 
  On March 8, 1998 the Company purchased a controlling interest in Hotkey
Internet Services Pty., Ltd. ("Hotkey"), a Melbourne, Australia based internet
service provider. The Company's 60% ownership of Hotkey was purchased for
approximately $1.3 million. Prior to the Company's investment in Hotkey,
Primus' chairman, K. Paul Singh, owned approximately 14% of Hotkey. As a
result of the transaction Mr. Singh owns 4% of Hotkey.
 
  On February 4, 1998 the Company entered into an Agreement and Plan of Merger
("the Agreement") with TresCom International, Inc. ("TresCom"), a facilities-
based international telecommunications provider specializing in traffic to the
Caribbean and Central and South America. The Agreement calls for the Company
to acquire all of the approximately 12.1 million outstanding TresCom shares at
a value of $10 per share, subject to certain potential adjustments, through an
exchange of the Company's shares of common stock. The transaction is subject
to, among other things the approval of both Primus and TresCom stockholders
and certain regulatory authorities.

                 PRIMUS TELECOMMUNICATIONS GROUP, INCORPORATED
 
                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
(1) BASIS OF PRESENTATION
 
  The accompanying unaudited consolidated financial statements have been
prepared in accordance with generally accepted accounting principles for
interim financial reporting and Securities and Exchange Commission ("SEC")
regulations. Certain information and footnote disclosures normally included in
the financial statements prepared in accordance with generally accepted
accounting principles have been condensed or omitted pursuant to such rules
and regulations. In the opinion of management, the financial statements
reflect all adjustments (of normal and recurring nature) which are necessary
to present fairly the financial position, results of operations and cash flows
for the interim periods. The results for the three months ended March 31, 1998
are not necessarily indicative of the results that may be expected for the
year ending December 31, 1998.
 
  The financial statements should be read in conjunction with the Company's
audited consolidated financial statements included in the Company's most
recently filed Form 10-K.
 
(2) MERGER, ACQUISITION AND INVESTMENT
 
  In February 1998 the Company entered into an Agreement and Plan of Merger
("the Agreement") with TresCom International, Inc. ("TresCom"), a facilities-
based 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. The Agreement was subsequently
amended in April 1998. The amended Agreement calls for the Company to acquire
all of the approximately 12.3 million TresCom common shares outstanding at a
value of $12 per share, through the exchange of the Company's shares of common
stock. The transaction is subject to, among other things, the approval of both
Primus and TresCom stockholders and certain regulatory authorities. The
transaction is expected to be completed by the end of the second quarter of
1998.
 
  Effective March 1, 1998 the Company purchased a controlling interest in
Hotkey Internet Services Pty., Ltd. ("Hotkey"), a Melbourne, Australia based
internet service provider. The Company's 60% ownership of Hotkey was purchased
through an investment in Hotkey of 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 based in Sydney, Australia. The Company paid approximately $1.8
million in cash and 27,500 shares of the Company's Common Stock for Eclipse.
 
(3) SUBSEQUENT EVENTS
 
  On April 27, 1998 the Company announced a proposed offering of senior notes
("1998 Senior Notes Offering") to be privately placed in reliance on an
exemption from the registration requirements of the Securities Act of 1934, as
amended. The Company expects to close such offering of $150 million principal
amount of its 9 7/8% Senior notes due 2008 on May 19, 1998, generating net
proceeds of approximately $145 million.
 
(4) LONG TERM OBLIGATIONS
 
    Long-term obligations consist of the following (in thousands):

                 PRIMUS TELECOMMUNICATIONS GROUP, INCORPORATED
 
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
    On August 4, 1997 the Company completed the sale of $225 million 11 3/4%
senior notes and warrants to purchase 392,654 shares of the Company's common
stock ("1997 Senior Notes and Warrants Offering"). The senior notes are due
August 1, 2004 with early redemption at the option of the Company at any time
after August 1, 2001. Dividends are currently restricted by the senior notes
indenture. Interest payments are due semi-annually on February 1st and August
1st. A portion of the proceeds from this offering have been pledged to secure
the first six semi-annual interest payments on the senior notes and are
reflected on the balance sheet as restricted investments. A portion of the
proceeds of this 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 materially differ from the effective
interest method.
 
(5) NEW ACCOUNTING PRONOUNCEMENTS
 
    In January 1998, the Company adopted the provisions of Statement of
Financial Accounting Standards No. 130, Reporting Comprehensive Income (SFAS
No. 130). Under SFAS No. 130, the Company's foreign currency translation
adjustments are considered to be components of other comprehensive income
(loss), and the stockholders' equity section of the accompanying balance sheet
has been reclassified accordingly. During the quarters ended March 31, 1998
and 1997, the Company's foreign currency translation adjustment totaled $ 1.1
million and $ (0.1) million, respectively. For the year ending December 31,
1998, the Company will report its net income (loss) and its foreign currency
translation income or loss within a separate statement of comprehensive income
(loss).
 
(6) RECLASSIFICATIONS
 
    Certain prior year amounts have been reclassified to conform to the current
year presentation.

                        REPORT OF INDEPENDENT AUDITORS
 
Board of Directors and Stockholders
USFI, Inc.
 
  We have audited the accompanying consolidated balance sheets of USFI, Inc.
and subsidiary as of December 31, 1996 and 1995, and the related consolidated
statements of operations, stockholders' deficit and cash flows for the years
then ended. 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, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of USFI, Inc.
and subsidiary at December 31, 1996 and 1995, and the results of their
operations and their cash flows for the years then ended in conformity with
generally accepted accounting principles.
 
  The accompanying financial statements have been prepared assuming that USFI,
Inc. will continue as a going concern. As more fully described in Note 2, the
Company has incurred recurring operating losses and has a working capital
deficiency and a deficit in stockholders' equity. These conditions raise
substantial doubt about the Company's ability to continue as a going concern.
Management's plans in regard to these matters are also described in Note 2.
The financial statements do not include any adjustments to reflect the
possible future effects on the recoverability and classification of assets or
the amounts and classification of liabilities that may result from the outcome
of this uncertainty.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                               DECEMBER 31, 1996
 
1. ORGANIZATION AND NATURE OF BUSINESS
 
   USFI, Inc. (the "Company") which was incorporated in New York on February
12, 1993, provides least cost routing for international long distance
telecommunication services, which primarily originate and terminate outside of
the United States. Substantially, all billings for service are denominated in
U.S. currency.
 
   Customers are principally located in Western Europe, Japan and South Africa.
No individual customer represents a significant percentage of revenues,
however, the Company utilizes outside agents to sell its services in certain
geographic areas, with agents in Germany and South Africa representing
customers with revenues aggregating 18% and 15%, and 13% and 10%,
respectively, of total 1996 and 1995 revenues. The Company performs a credit
evaluation of all new customers and requires certain customers to provide
collateral in the form of a cash deposit or letter of credit. At December 31,
1996 and 1995, the Company had letters of credit issued on its behalf from
customers in the amount of approximately $327,000 and $525,000, respectively.
 
   On May 15, 1995 the Company acquired a 51% interest in Mastercall, Ltd.
("Mastercall"), a joint venture that resells the Company's international
telecommunications services in the United Kingdom, for a purchase price of
approximately $148,000. The acquisition was accounted for using the purchase
method of accounting and the results of operations have been included in the
financial statements of the Company from the date of acquisition.
 
2. BASIS OF PRESENTATION
 
   The accompanying financial statements have been prepared on the basis that
the Company will continue as a going concern, which contemplates the
realization of assets and the satisfaction of liabilities in the normal course
of business. The Company has incurred losses since inception and has a working
capital deficiency and a deficit in stockholders' equity as of December 31,
1996. All of these matters raise substantial doubt about the Company's ability
to continue as a going concern. The Company plans on selling its assets and
ceasing its operations (see Note 10) and, on September 11, 1997, the Company
entered into a letter of intent to sell all of its assets, except for cash and
accounts and notes receivable. The financial statements do not include any
adjustments to reflect the possible future effects on the recoverability and
classification of assets or the amounts or classifications of liabilities that
may result from the outcome of this uncertainty.
 
   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
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
3. SIGNIFICANT ACCOUNT POLICIES
 
  Depreciation
 
   Furniture and equipment are recorded at cost and are depreciated over the
estimated useful lives of three to five years, utilizing the straight-line
method. Assets acquired pursuant to capital lease arrangements and leasehold
improvements are amortized on a straight-line basis over the shorter of their
estimated useful lives or the terms of the leases. Depreciation expense for
the years ended December 31, 1996 and 1995 was $652,000 and $371,000,
respectively.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
 Deferred Costs and Goodwill
 
  Deferred costs include costs to obtain trademarks and certain organizational
costs. Goodwill includes approximately $127,000 relating to the 1995
acquisition of Mastercall (see Note 1). Such deferred costs are amortized on
the straight-line basis generally as follows:

   ASSET                                                            AMORTIZATION

   <S>                                                              <C>
   Trademarks......................................................    5 years
   Organization costs..............................................    5 years
   Goodwill........................................................   15 years
</TABLE>
 
  The carrying amount of goodwill is reviewed if facts and circumstances
suggest that it may be impaired. Due to recurring losses of Mastercall, the
Company evaluated the ongoing value of goodwill, as determined based on the
estimated undiscounted cash flows of the entity over the remaining
amortization period and determined that goodwill with a carrying value of
$113,000 is impaired. As a result, the Company has recorded a charge in 1996
to write-off the full amount of goodwill associated with Mastercall, which is
included in selling, general and administrative expenses.
 
 Revenue Recognition
 
  The Company recognizes revenue from services and the related costs at the
time the services are rendered.
 
 Income Tax
 
  Income taxes are accounted for under the liability method in accordance with
Statement of Financial Accounting Standards No. 109, Accounting for Income
Taxes.
 
 Basis of Consolidation
 
  The consolidated financial statements include the accounts of the Company
and Mastercall. All significant intercompany accounts and transactions have
been eliminated.
 
 Basis of Presentation
 
  Certain amounts in the 1995 financial statements have been reclassified to
conform with the 1996 presentation.
 
4. PROPERTY AND EQUIPMENT
 
  Property and equipment is comprised of the following at December 31, 1996

 Litigation
 
  During 1994, the Company was involved in a contract dispute which was
presented to an arbitrator and, in August 1995, an award in the amount of
$333,450 representing damages and administrative fees and costs was determined
to be payable by the Company. The award amount was recorded as an expense in
1994 and was paid in 1996.
 
  The Company is involved in litigation in the normal course of business. In
the opinion of management, such litigation will not have a material effect on
the Company's cash flows, financial condition or results of operations.
 
 Incentive Plans
 
  The Company maintains incentive plans which entitle certain key employees to
participate in certain distributions, if any, by the Company of cash or
property to two of the Company's principal stockholders. Participation
commences when the amount of distributions paid exceeds certain stipulated
amounts. No such distributions have been made or are expected.
 
6. MAJOR SUPPLIERS
 
  During 1996 and 1995, MCI, World Com, Inc. (formerly IDB) and Cable and
Wireless International, Inc. provided the Company with a majority of its
international telecommunications network services. Charges for such services
are included in cost of telecommunications services in the accompanying
statement of operations.
 
7. RELATED PARTIES
 
  In March 1995, the Company entered into an agreement with TelePassport Japan
Co., Ltd. ("TelePassport Japan"), an affiliated joint venture formed in 1995,
to provide international telecommunication services and to lease switching
equipment to TelePassport Japan. Telecommunication revenue for 1996 and 1995
includes $3,400,000 and $371,000, respectively, for services provided to
TelePassport Japan. The equipment under lease has a net book value of $140,000
and $186,000 at December 31, 1996 and 1995, respectively, and is included in
property and equipment. The joint venture was terminated in 1997 and the
equipment was transferred to an affiliate.
 
  Included in due to affiliates at December 31, 1995 is a $1,258,000 note due
to US Cable Corporation ("US Cable"), an affiliate of certain stockholders.
During 1996, US Cable transferred the note to such stockholders who

of the Company and amounts due to US Cable for expenses paid on behalf of the
Company.
 
8. EMPLOYEE BENEFIT PLAN
 
  The Company sponsors a defined contribution plan that qualifies as a
deferred salary arrangement under Section 401(a) of the Internal Revenue Code.
All full-time employees meeting minimum service requirements are eligible to
participate and may contribute up to 18% of their pre-tax earnings subject to
certain Internal Revenue Code restrictions. The Company matches 50% of each

Company contributions for 1996 and 1995 of $16,000 and $14,000, respectively,
are included in selling, general and administrative expenses.
 
9. INCOME TAXES
 
  The Company has elected to be taxed as an "S" Corporation for federal income
tax purposes. For New York City income tax purposes, the Company is taxed as a
"C" corporation and at December 31, 1996 the Company has available New York
City net operating loss carryforwards of $8,488,000, which principally expire
in the year 2011. At December 31, 1996, the Company had deferred city income
tax assets of $1,132,000, which are primarily attributable to temporary
differences which are not currently deductible for income tax purposes,
including net operating loss carryforwards, accrued liabilities and certain
other reserves. The Company has recorded a full valuation allowance against
its deferred tax assets at December 31, 1996.
 
10. SUBSEQUENT EVENTS
 
  On March 10, 1997, the Company acquired the remaining 49% interest in
Mastercall for a purchase price of approximately $15,000.
 
  During 1997, the Company and certain affiliates planned an initial public
offering of common stock. The initial public offering was postponed in April
1997 and subsequently abandoned, and accordingly, the initial public offering
was not completed. Costs incurred as of December 31, 1996 related to the
initial public offering of $284,000 are included in 1996 selling, general and
administrative expenses.
 
  On September 11, 1997, the Company entered into a letter of intent to sell

Telecommunications Group, Incorporated. Subsequent to the sale, the Company
intends to cease operations.

                         SEPTEMBER 30, 1997 AND 1996)
 
1. ORGANIZATION AND NATURE OF BUSINESS
 
  USFI, Inc. (the "Company") which was incorporated in New York on February
12, 1993, provides least cost routing for international long distance
telecommunication services, which primarily originate and terminate outside of
the United States. Substantially, all billings for service are denominated in
U.S. currency.
 
  On September 11, 1997, the Company entered into a letter of intent to sell
most of its assets, except for cash and accounts and notes receivable to
Primus Telecommunications Group, Inc. ("Primus"). (See Note 7.)
 
2. BASIS OF PRESENTATION
 
  The accompanying financial statements have been prepared on the basis that
the Company will continue as a going concern, which contemplates the
realization of assets and the satisfaction of liabilities in the normal course
of business. The Company has incurred losses since inception and has a working
capital deficiency and a deficit in stockholders' equity as of September 30,
1997. On October 20, 1997, the Company sold most of its assets (see Note 7) to
Primus and began to terminate its business. All of these matters raise
substantial doubt about the Company's ability to continue as a going concern.
The financial statements do not include any adjustments to reflect the
possible future effects on the recoverability and classification of assets or
the amounts or classifications of liabilities that may result from the outcome
of this uncertainty.
 
  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
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
3. SIGNIFICANT ACCOUNTING POLICIES
 
 Depreciation
 
  Furniture and equipment are recorded at cost and are depreciated over the
estimated useful lives of three to five years, utilizing the straight-line
method. Assets acquired pursuant to capital lease arrangements and leasehold
improvements are amortized on a straight-line basis over the shorter of their
estimated useful lives or the terms of the leases. Depreciation expense for
the nine months ended September 30, 1997 and 1996 was $626,000 and $496,000,
respectively.
 
 Deferred Costs
 
  Deferred costs include costs to obtain trademarks and certain organizational
costs. Such deferred costs are amortized on the straight-line basis generally
as follows:

                        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.

                (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
approximately $120 for 1997.
 
 Advertising
 
  Pursuant to American Institute of Certified Public Accountants (AICPA)
Statement of Position No. 93-7, "Reporting on Advertising Costs," TresCom
expenses advertising costs as incurred except for direct-
 
                                     F-47

                          TRESCOM INTERNATIONAL, INC.
 
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
                (IN THOUSANDS, EXCEPT SHARE AND PER SHARE DATA)
response 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.

                (IN THOUSANDS, EXCEPT SHARE AND PER SHARE DATA)
 
 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.

  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 leases consist of:

  On February 13, 1996, TresCom sold 4,545,455 shares of its common stock at
$12 per share in its IPO. The net proceeds of this sale were approximately
$48,600. The net proceeds were used to retire debt and accrued interest of
approximately $35,800.
 
 Stock Option Plan
 
  TresCom has a stock option plan under which 936,432 options to purchase
shares of common stock may be granted to officers, key employees, consultants
and directors. The plan allows the granting of incentive stock options, which
may not have an exercise price below the greater of par value or the market
value on the date of grant, and non-qualified stock options, which may not
have an exercise price below par value. All options must be exercised no later
than 10 years from the date of grant. No option may be granted under the plan
after February 22, 2004.
 
  Options generally vest as to 20% on the first anniversary of the vesting
commencement date or grant date and as to an additional 20% on each
anniversary thereafter. All options expire on the tenth anniversary of the
grant date, unless sooner terminated under the terms of the stock option plan.
In the event of certain changes in control of TresCom, all options become
fully vested.

  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.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
                (IN THOUSANDS, EXCEPT SHARE AND PER SHARE DATA)
  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:

  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.

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.

1. GENERAL
 
 Organization and Basts of Presentation
 
  TresCom International, Inc. (together with its subsidiaries collectively
referred to as the "Company") is a facilities-based long-distance

  These financial statements have been prepared in accordance with generally
accepted accounting principles for interim financial reporting and Securities
and Exchange Commission regulations. Certain information and footnote
disclosures normally included to financial statements prepared in accordance
with generally accepted accounting principles have been condensed or omitted
pursuant to such regulations. In the opinion of management, the information
contained herein reflects all adjustments necessary to make the financial
position, results of operations and cash flows for the interim periods a fair
representation. All such adjustments are of a normal recurring nature. 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 disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amount of revenues and expenses during the reporting period.
Actual results could differ from those estimates. These financial statements
should be read in conjunction with the Company's Annual Report on Form 10-K
for the fiscal year ended December 31, 1997. The results of operations for the
interim periods shown are not necessarily indicative of results of operations
to be expected for the entire fiscal year.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Reference should be made to the Notes to Consolidated Financial Statements
in the Company's Annual Report on Form 10-K for the fiscal year ended December
31, 1997, specifically Note 2, for a summary of the Company's significant
accounting policies.
 
 Reclassification
 
  Certain prior year amounts have been reclassified to conform with current
year presentation.
 
 New Accounting Pronouncement
 
  In 1997, the Financial Accounting Standards Board issued Statement No. 128,
"Earnings Per Share" ("SFAS 128"). SFAS 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 with SFAS 128.

of Merger, which was subsequently amended by Amendments No. 1 and 2, dated as
of April 8, 1998 and as of April 16, 1998, respectively, with Primus
Telecommunications Group, Incorporated ("Primus") and Taurus Acquisition

surviving corporation and that Primus will acquire 100% of the issued and
outstanding shares of the Company's 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' and the Company's shareholders and
certain regulatory authorities.

                    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 Primus's Amended and Restated By-Laws provides that
Primus, to the full extent permitted by Section 145 of the DGCL, shall
indemnify all past and present directors or officers of Primus and may
indemnify all past or present employees or other agents of Primus. To the
extent that a director, officer, employee or agent of Primus 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 Primus against actually and
reasonably incurred expenses in connection therewith. Such expenses may be
paid by Primus 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 Primus's
Amended and Restated Certificate of Incorporation provides that no director of
Primus shall be liable to Primus 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 Primus or its 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
Primus's capital stock or (iv) for any transaction from which the director
derived an improper personal benefit.
 
  Primus has obtained a policy insuring it and its directors and officers
against certain liabilities, including liabilities under the 1933 Act.
 
  Pursuant to Section 5(h) of the Merger Agreement, Primus 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 (the "Effective Time") 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 Surviving Corporation 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
Company pursuant to the foregoing provisions, or otherwise, 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
Company 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 Company 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.

mailed to a Holder in the manner herein prescribed shall be conclusively deemed
to have been received by such Holder, whether or not such Holder actually
receives such notice.  Where this

                                     -23-
<PAGE>
 
Indenture provides for notice in any manner, such notice may be waived in
writing by the Person entitled to receive such notice, either before or after
the event, and such waiver shall be the equivalent of such notice.  Waivers of
notice by Holders shall be filed with the Trustee, but such filing shall not be
a condition precedent to the validity of any action taken in reliance upon such
waiver.

          In case by reason of the suspension of or irregularities in regular
mail service or by reason of any other cause, it shall be impracticable to mail
notice of any event to Holders when such notice is required to be given pursuant
to any provision of this Indenture, then any manner of giving such notice as
shall be satisfactory to the Trustee shall be deemed to be a sufficient giving
of such notice for every purpose hereunder.

          SECTION 108.  Effect of Headings and Table of Contents.
                        ----------------------------------------

          SECTION 110.  Separability Clause.
                        ------------------- 

          In case any provision in this Indenture or in the Notes shall be
invalid, illegal or unenforceable, the validity, legality and enforceability of
the remaining provisions shall not in any way be affected or impaired thereby.

          SECTION 111.  Benefits of Indenture.
                        --------------------- 

          Nothing in this Indenture or in the Notes, express or implied, shall
give to any Person, other than the parties hereto, any Paying Agent, any Notes
Registrar and their successors hereunder, and the Holders, any benefit or any
legal or equitable right, remedy or claim under this Indenture.

          SECTION 112.  Governing Law.
                        ------------- 

          This Indenture and the Notes shall be governed by and construed in
accordance with the law of the State of New York.  Upon the issuance of Exchange
Notes, if any, or the effectiveness of the Shelf Registration Statement, this
Indenture will be subject to the provisions of the Trust Indenture Act that are
required to be part of this Indenture and shall, to the extent applicable, be
governed by such provisions.  Each of the parties hereto submits to the
jurisdiction of the U.S. federal and any New York state court located in the
Borough of Manhattan, City and State of New York with respect to any actions
brought against it as defendant in any suit, action or proceeding

                                     -24-
<PAGE>
 
arising out of or relative to this Indenture or the Notes and waives any rights
to which it may be entitled on account of place of residence or domicile.

          SECTION 113.  Legal Holidays.
                        -------------- 

          In any case where any Interest Payment Date, Redemption Date, sinking
fund payment date or Stated Maturity or Maturity of any Note shall not be a
Business Day, then (notwithstanding any other provision of this Indenture or of
the Notes) payment of  principal (or premium, if any) or interest need not be
made on such date, but may be made on the next succeeding Business Day with the
same force and effect as if made on the Interest Payment Date, Redemption Date
or sinking fund payment date, or at the Stated Maturity or Maturity; provided
                                                                     --------
that no interest shall accrue for the period from and after such Interest
Payment Date, Redemption Date, sinking fund payment date, Stated Maturity or
Maturity, as the case may be.

          SECTION 114.  Currency Indemnity.
                        ------------------ 

          U.S. dollars are the sole currency of account and payment for all sums
payable by the Company 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 the winding-up or dissolution of the Company or otherwise) by
any Holder of a Note in respect of any sum expressed to be due to it from the
Company shall only constitute a discharge to the Company 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,
the Company shall indemnify the recipient against any loss sustained by it as a
result.  In any event, the Company shall indemnify the recipient against the
cost of making any such purchase.  For the purposes of this Section 114, 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 the Company's 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.

               REGULATION S OR (E) PURSUANT TO ANOTHER AVAILABLE EXEMPTION FROM
               THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND (3)

               RESPECTIVE MEANINGS GIVEN TO THEM BY REGULATION S UNDER THE

2008," in each case, of the Company.  The Stated Maturity of the Notes shall be

          The Notes shall be executed on behalf of the Company by its Chairman,
its President or a Vice President, and attested by its Secretary, an Assistant
Secretary or any Vice President. The signature of any of these officers on the
Notes may be manual or facsimile signatures of the present or any future such
authorized officer and may be imprinted or otherwise reproduced on the Notes.

          Notes bearing the manual or facsimile signatures of individuals who
were at any time the proper officers of the Company shall bind the Company,
notwithstanding that such individuals or any of them have ceased to hold such
offices prior to the authentication and delivery of such Notes or did not hold
such offices at the date of such Notes.

          At any time and from time to time after the execution and delivery of

          At any time and from time to time after the execution and delivery of
this Indenture, the Company may deliver Initial Notes executed by the Company to
the Trustee for authentication, together with a Company Order for the
authentication and delivery of such Initial Notes directing the Trustee to
authenticate the Notes and certifying that all conditions precedent to the
issuance of Notes contained herein have been fully complied with, and the
Trustee in accordance with such Company Order shall authenticate and deliver
such Initial Notes. On Company Order, the Trustee shall authenticate for
original issue Exchange Notes in an aggregate principal amount not to exceed
$150,000,000; provided that such Exchange Notes shall be issuable only upon the
valid surrender for cancellation of Initial Notes of a like aggregate principal
amount in accordance with an Exchange Offer pursuant to the Registration Rights
Agreement and a Company Order for the authentication of such securities
certifying that all conditions precedent to the issuance have been complied with
(including the effectiveness of a registration statement related thereto). In
each case, the Trustee shall be entitled to receive an Officer's Certificate and
an Opinion of Counsel of the Company that it may reasonably request in
connection with such authentication of Notes. Such order shall specify the
amount of Notes to be authenticated and the date on which the original issue of
Initial Notes or Exchange Notes is to be authenticated.

          Each Note shall be dated the date of its authentication.

          No Note shall be entitled to any benefit under this Indenture or be
valid or obligatory for any purpose unless there appears on such Note a
certificate of authentication substantially in the form provided for in Exhibit
A, duly executed by the Trustee by manual signature of an authorized officer,
and such certificate upon any Note shall be conclusive evidence, and the only
evidence, that such Note has been duly authenticated and delivered hereunder and
is entitled to the benefits of this Indenture.

          In case the Company, pursuant to Article Eight, shall be consolidated
or merged with or into any other Person or shall convey, transfer, lease or
otherwise dispose of its properties and assets substantially as an entirety to
any Person, and the successor Person resulting from such consolidation, or
surviving such merger, or into which the Company shall have been merged, or the
Person which shall have received a conveyance, transfer, lease or other
disposition as aforesaid, shall have executed an indenture supplemental hereto
with the Trustee pursuant to Article Eight, any of the Notes authenticated or
delivered prior to such consolidation, merger, conveyance, transfer, lease or
other disposition may, from time to time, at the request of the successor
Person, be exchanged for other Notes executed in the name of the successor
Person with such changes in phraseology and form as may be appropriate, but
otherwise in substance of like tenor as the Notes surrendered for such exchange
and of like principal amount; and the Trustee, upon Company Request of the
successor Person, shall authenticate and deliver Notes as specified in such
request for the purpose of such exchange.  If Notes shall at any time be
authenticated and delivered in any new name of a successor Person pursuant to
this Section in exchange or substitution for or upon registration of transfer of
any Notes, such successor Person, at the option of the Holders but without
expense to them, shall provide for the exchange of all Notes at the time
Outstanding for Notes authenticated and delivered in such new name.

          SECTION 304.  Temporary Notes.
                        --------------- 

          Pending the preparation of definitive Notes, the Company may execute,
and upon Company Order the Trustee shall authenticate and deliver, temporary
Notes which are printed, lithographed, typewritten, mimeographed or otherwise
produced, in any authorized denomination, substantially of the tenor of the
definitive Notes in lieu of which they are issued and with such appropriate
insertions, omissions, substitutions and other variations as the officers
executing such Notes may determine, as conclusively evidenced by their execution
of such Notes.

          If temporary Notes are issued, the Company will cause definitive Notes
to be prepared without unreasonable delay. After the preparation of definitive
Notes, the temporary Notes shall be exchangeable for definitive Notes upon
surrender of the temporary Notes at the office or agency of the Company
designated for such purpose pursuant to Section 1002, without charge to the
Holder. Upon surrender for cancellation of any one or more temporary Notes, the
Company shall execute and upon Company Order the Trustee shall authenticate and
deliver in exchange therefor a like principal amount of definitive Notes of
authorized denominations. Until so exchanged, the temporary Notes shall in all
respects be entitled to the same benefits under this Indenture as definitive
Notes.

          SECTION 305.  Registration, Registration of Transfer and Exchange.
                        --------------------------------------------------- 

          The Company shall cause to be kept at the Corporate Trust Office of
the Trustee a register (the register maintained in such office and in any other
office or agency designated pursuant to Section 1002 being herein sometimes
referred to as the "Note Register") in which, subject to such reasonable
regulations as it may prescribe, the Company shall provide for the registration
of Notes and of transfers of Notes. The Note Register shall be in written form
or any other form capable of being converted into written form within a
reasonable time. At all reasonable times, the Note Register shall be open to
inspection by the Trustee. The Trustee is hereby initially appointed as security
registrar (the "Note Registrar") for the purpose of registering Notes and
transfers of Notes as herein provided.

          Upon surrender for registration of transfer of any Note at the office
or agency of the Company designated pursuant to Section 1002, the Company shall
execute, and upon Company Order the Trustee shall authenticate and deliver, in
the name of the designated transferee or transferees, one or more new Notes of
any authorized denomination or denominations of a like aggregate principal
amount.

          At the option of the Holder, Notes may be exchanged for other Notes of
any authorized denomination and of a like aggregate principal amount, upon
surrender of the Notes to be exchanged at such office or agency.  Whenever any
Notes are so surrendered for exchange, the Company shall execute, and upon
Company Order the Trustee shall authenticate and deliver, the Notes which the
Holder making the exchange is entitled to receive; provided that no exchange of
                                                   --------                    
Initial Notes for Exchange Notes shall occur until an Exchange Offer
Registration Statement shall have been declared effective by the Commission, the
Trustee shall have received an Officer's

<PAGE>
 
Certificate confirming that the Exchange Offer Registration Statement has been
declared effective by the Commission and that the Initial Notes to be exchanged
for the Exchange Notes shall be canceled by the Trustee.

          All Notes issued upon any registration of transfer or exchange of
Notes shall be the valid obligations of the Company, evidencing the same debt,
and entitled to the same benefits under this Indenture, as the Notes surrendered
upon such registration of transfer or exchange.

          Every Note presented or surrendered for registration of transfer or
for exchange shall be duly endorsed and be accompanied by a written instrument
of transfer, in form satisfactory to the Company and the Note Registrar, duly
executed by the Holder thereof or his attorney duly authorized in writing.

          No service charge shall be made for any registration of transfer or
exchange or redemption of Notes, but the Company may require payment of a sum
sufficient to cover any tax or other governmental charge that may be imposed in
connection with any registration of transfer or exchange of Notes, other than
exchanges pursuant to Section 304, 906, 1010, 1017 or 1108 not involving any
transfer.

          The Company shall not be required (i) to issue, register the transfer
of or exchange any Note during a period beginning at the opening of business 15
days before the selection of Notes to be redeemed under Section 1104 and ending
at the close of business on the day of such mailing of the relevant notice of
redemption, or (ii) to register the transfer of or exchange any Note so selected
for redemption in whole or in part, except the unredeemed portion of any Note
being redeemed in part.

          SECTION 306.  Book-Entry Provisions for Global Notes.
                        -------------------------------------- 

          (a)  Each Global Note initially shall (i) be registered in the name of
the Depositary for such Global Note or the nominee of such Depositary, (ii) be
delivered to the Trustee as custodian for such Depositary and (iii) bear legends
as set forth in Section 202.

          Members of, or participants in, the Depositary ("Agent Members") shall
have no rights under this Indenture with respect to any Global Note held on
their behalf by the Depositary, or the Trustee as its custodian, or under the
Global Note, and the Depositary may be treated by the Company, the Trustee and
any agent of the Company or the Trustee as the absolute owner of such Global
Note for all purposes whatsoever. Notwithstanding the foregoing, nothing herein
shall prevent the Company, the Trustee or any agent of the Company or the
Trustee, from giving effect to any written certification, proxy or other
authorization furnished by the Depositary or shall impair, as between the
Depositary and its Agent Members, the operation of customary practices governing
the exercise of the rights of a holder of any Note.

                                      -33-
<PAGE>
 
          (b)  Transfers of a Global Note shall be limited to transfers of such
Global Note in whole, but not in part, to the Depositary, its successors or
their respective nominees, except (i) as otherwise set forth in Section 307 and
(ii) U.S. Physical Notes or Offshore Physical Notes shall be transferred to all
beneficial owners in exchange for their beneficial interests in the U.S. Global
Note or the Offshore Global Note, respectively, in the event that the Depositary
notifies the Company that it is unwilling or unable to continue as Depositary
for the applicable Global Note or the Depositary ceases to be a "Clearing
Agency" registered under the Exchange Act and a successor depositary is not
appointed by the Company within 90 days. Interests of beneficial owners in a
Global Note may be transferred in accordance with the rules and procedures of
the Depositary and the provisions of Section 307. In connection with the
transfer of an entire Global Note to beneficial owners pursuant to clause (ii)
of this paragraph (b), the applicable Global Note shall be deemed to be
surrendered to the Trustee for cancellation, and the Company shall execute, and
the Trustee shall authenticate and deliver, to each beneficial owner identified
by the Depositary in exchange for its beneficial interest in the applicable
Global Note, an equal aggregate principal amount at maturity of U.S. Physical
Notes (in the case of the U.S. Global Note) or Offshore Physical Notes (in the
case of the Offshore Global Note), as the case may be, of authorized
denominations.

          (c)  Any beneficial interest in one of the Global Notes that is
transferred to a Person who takes delivery in the form of an interest in the
other Global Note will, upon transfer, cease to be an interest in such Global
Note and become an interest in the other Global Note and, accordingly, will
thereafter be subject to all transfer restrictions, if any, and other procedures
applicable to beneficial interests in such other Global Note for as long as it
remains such an interest.

          (d)  Any U.S. Physical Note delivered in exchange for an interest in
the U.S. Global Note pursuant to paragraph (b) of this Section shall, unless
such change is made on or after the Resale Restriction Termination Date and
except as otherwise provided in Section 307, bear the Private Placement Legend.

          (e)  The registered holder of a Global Note may grant proxies and
otherwise authorize any person, including Agent Members and persons that may
hold interests through Agent Members, to take any action which a Holder is
entitled to take under this Indenture or the Notes.

          SECTION 307.  Transfer Provisions.
                        ------------------- 

          Unless and until (i) an Initial Note is sold pursuant to an effective
Registration Statement, or (ii) an Initial Note is exchanged for an Exchange
Note in the Exchange Offer pursuant to an effective Registration Statement, in
each case, pursuant to the Registration Rights Agreement, the following
provisions shall apply:

          (a)  General.  The provisions of this Section 307 shall apply to all
               -------                                                        
     transfers involving any Physical Note and any beneficial interest in any
     Global Note.

     of a certificate by a transferee or transferor means the delivery to the
     Note Registrar by such transferee or transferor of the applicable
     certificate duly completed; "holding" includes both possession of a
     Physical Note and ownership of a beneficial interest in a Global Note, as
     the context requires; "transferring" a Global Note means transferring that
     portion of the principal amount of the transferor's beneficial interest
     therein that the transferor has notified the Note Registrar that it has
     agreed to transfer; and "transferring" a Physical Note means transferring
     that portion of the principal amount thereof that the transferor has
     notified the Note Registrar that it has agreed to transfer.

          As used in this Indenture, "Accredited Investor Certificate" means a
     certificate substantially in the form set forth in Exhibit C; "Regulation S
     Certificate" means a certificate substantially in the form set forth in
     Exhibit D; "Rule 144A Certificate" means a certificate substantially in the
     form set forth in Exhibit E; and "Non-Registration Opinion and Supporting
     Evidence" means a written opinion of counsel reasonably acceptable to the
     Company to the effect that, and such other certification or information as
     the Company may reasonably require to confirm that, the proposed transfer
     is being made pursuant to an exemption from, or in a transaction not
     subject to, the registration requirements of the Securities Act.

          (c)  [Intentionally Omitted]

          (d)  Deemed Delivery of a Rule 144A Certificate in Certain
               -----------------------------------------------------
     Circumstances.  A Rule 144A Certificate, if not actually delivered, will be

     deemed delivered if (A) (i) the transferor advises the Company and the
     Trustee in writing that the relevant offer and sale were made in accordance
     with the provisions of Rule 144A (or, in the case of a transfer of a
     Physical Note, the transferor checks the box provided on the Physical Note
     to that effect) and (ii) the transferee advises the Company and the Trustee
     in writing that (x) it and, if applicable, each account for which it is
     acting in connection with the relevant transfer, is a qualified
     institutional buyer within the meaning of Rule 144A, (y) it is aware that
     the transfer of Notes to it is being made in reliance on the exemption from
     the provisions of Section 5 of the Securities Act provided by Rule 144A,
     and (z) if at any time the Company is not subject to Section 13 or 15(d) of
     the Exchange Act, prior to the proposed date of transfer the transferee has
     been given the opportunity to obtain from the Company the information
     referred to in Rule 144A(d)(4), and has either declined such opportunity or
     has received such information (or, in the case of a transfer of a Physical
     Note, the transferee signs the certification provided on the Physical Note
     to that effect); or (B) the transferor holds the U.S. Global Note and is
     transferring to a transferee that will take delivery in the form of the
     U.S. Global Note.

          If (i) any mutilated Note is surrendered to the Trustee, or (ii) the
Company and the Trustee receive evidence to their satisfaction of the
destruction, loss or theft of any Note, and there is delivered to the Company
and the Trustee such security or indemnity as may be required by them to save
each of them harmless, then, in the absence of written notice to the Company or
the Trustee that such Note has been acquired by a bona fide purchaser, the
Company shall execute and upon Company Order the Trustee shall authenticate and
deliver, in exchange for any such mutilated Note or in lieu of any such
destroyed, lost or stolen Note, a new Note of like tenor and principal amount,
bearing a number not contemporaneously outstanding.

          In case any such mutilated, destroyed, lost or stolen Note has become
or is about to become due and payable, the Company in its discretion may,
instead of issuing a new Note, pay such Note.

          Upon the issuance of any new Note under this Section 308, the Company
may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and shall require
the payment of a sum sufficient to pay any other expenses (including the fees
and expenses of the Trustee) connected therewith.

          Every new Note issued pursuant to this Section 308 in lieu of any
mutilated, destroyed, lost or stolen Note shall constitute an original
additional contractual obligation of the Company, whether or not the mutilated,
destroyed, lost or stolen Note shall be at any time enforceable by anyone, and
shall be entitled to all benefits of this Indenture equally and proportionately
with any and all other Notes duly issued hereunder.

          The provisions of this Section 308 are exclusive and shall preclude
(to the extent lawful) all other rights and remedies with respect to the
replacement or payment of mutilated, destroyed, lost or stolen Notes.

provided for, on any Interest Payment Date shall be paid to the Person in whose
name such Note (or one or more Predecessor Notes) is registered at the close of
business on the Regular Record Date for such interest at the office or agency of
the Company maintained for such purpose pursuant to Section 1002;

                                      -43-

order of the Person entitled thereto pursuant to Section 310, to the address of
such Person as it appears in the Note Register or (ii) transferring the interest
payment to an account located in the United States maintained by the payee.

          Any interest on any Note which is payable, but is not punctually paid
or duly provided for, on any Interest Payment Date shall forthwith cease to be
payable to the Holder on the Regular Record Date by virtue of having been such
Holder, and such defaulted interest and (to the extent lawful) interest on such
defaulted interest at the rate borne by the Notes (such defaulted interest and
interest thereon herein collectively called "Defaulted Interest") may be paid by
the Company, at its election in each case, as provided in clause (1) or (2)
below:

          (1)  The Company may elect to make payment of any Defaulted Interest
     to the Persons in whose names the Notes (or their respective Predecessor
     Notes) are registered at the close of business on a Special Record Date for
     the payment of such Defaulted Interest, which shall be fixed in the
     following manner. The Company shall notify the Trustee in writing of the
     amount of Defaulted Interest proposed to be paid on each Note and the date
     of the proposed payment, and at the same time the Company shall deposit
     with the Trustee an amount of money equal to the aggregate amount proposed
     to be paid in respect of such Defaulted Interest or shall make arrangements
     satisfactory to the Trustee for such deposit prior to the date of the
     proposed payment, such money when deposited to be held in trust for the
     benefit of the Persons entitled to such Defaulted Interest as in this
     clause provided. Thereupon the Company, with the written consent of the
     Trustee, shall fix a Special Record Date for the payment of such Defaulted
     Interest which shall be not more than 15 days and not less than 10 days
     prior to the date of the proposed payment and not less than 10 days after
     the receipt by the Trustee of the notice of the proposed payment. The
     Trustee, in the name and at the expense of the Company, shall cause notice
     of the proposed payment of such Defaulted Interest and the Special Record
     Date therefor to be given in the manner provided for in Section 106, not
     less than 10 days prior to such Special Record Date. Notice of the proposed
     payment of such Defaulted Interest and the Special Record Date therefor
     having been so given, such Defaulted Interest shall be paid to the Persons
     in whose names the Notes (or their respective Predecessor Notes) are
     registered at the close of business on such Special Record Date and shall
     no longer be payable pursuant to the following clause (2).

          (2)  The Company may make payment of any Defaulted Interest in any
     other lawful manner not inconsistent with the requirements of any
     securities exchange on which the Notes may be listed, and upon such notice
     as may be required by such exchange, if, after notice given by the Company
     to the Trustee of the proposed payment pursuant to this clause, such manner
     of payment shall be deemed practicable by the Trustee.

and delivered hereunder which the Company may have acquired in any manner
whatsoever, and may deliver to the Trustee (or to any other Person for delivery
to the Trustee) for cancellation any Notes previously authenticated hereunder
which the Company has not issued and sold, and all Notes so delivered shall be
promptly cancelled by the Trustee. If the Company shall so acquire any of the
Notes, however, such acquisition shall not operate as a redemption or
satisfaction of the indebtedness represented by such Notes unless and until the
same are surrendered to the Trustee for cancellation. No Notes shall be
authenticated in lieu of or in exchange for any Notes cancelled as provided in
this Section, except as expressly permitted by this Indenture. All cancelled
Notes held by the Trustee shall be disposed of by the Trustee in accordance with
its customary procedures and certification of their disposal delivered to the
Company unless by Company Order the Company shall direct that cancelled Notes be
returned to it after being appropriately designated as cancelled.

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

          The Company in issuing the Notes may use "CUSIP" numbers (if then
generally in use), and, if so, the Trustee shall use "CUSIP" numbers in notices
of redemption or other notices to Holders as a convenience to Holders; provided
                                                                       --------

          cancellation

                    (i)   have become due and payable, or

                    (ii)  will become due and payable at their Stated Maturity
               within one year, or

                    (iii) are to be called for redemption within one year under

               of redemption by the Trustee in the name, and at the expense, of
               the Company,

          and the Company, in the case of (i), (ii) or (iii) above, has

          delivered to the Trustee for cancellation, for principal (and premium,
          if any) and interest and Liquidated Damages, if any, to the date of

          Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Trustee under Section 606 and, if money shall
have been deposited with the Trustee pursuant to subclause (b) of clause (1) of
this Section, the obligations of the Trustee under Section 402 and the last

          SECTION 402.  Application of Trust Money.
                        -------------------------- 

          On or prior to the effective date of this Indenture, the Trustee shall

shall make payments to the Holders in accordance with this Indenture and the
Notes.  Subject to the provisions of the last paragraph of Section 1003, all

          SECTION 502.  Acceleration of Maturity; Rescission and Annulment.
                        -------------------------------------------------- 

          If an Event of Default (other than an Event of Default specified in
Section 501(8) or 501(9)) occurs and is continuing, then and in every such case
the Trustee or the Holders of not less than 25% in principal amount of the Notes
Outstanding may, and the Trustee at the request of such Holders shall, declare
the principal of, premium, if any, and accrued but unpaid interest on all the
Notes to be due and payable immediately, by a notice in writing to the Company
(and to the Trustee if given by Holders), and upon any such declaration of
acceleration, such principal of, premium, if any, and accrued interest shall
become immediately due and payable.  If an Event of Default specified in Section
501(8) or 501(9) occurs and is continuing, then the principal amount of all the
Notes 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.

          At any time after a declaration of acceleration has been made, the
Holders of a majority in principal amount of the Notes Outstanding, by written
notice to the Company and the Trustee, may waive all past defaults and rescind
and annul such declaration and its consequences if

          (1)  the Company has paid or deposited with the Trustee a sum
     sufficient to pay,

               (A)  all overdue interest and Liquidated Damages on all
          Outstanding Notes,

                                      -49-
<PAGE>
 
               (B)  all unpaid principal of (and premium, if any, on) any
          Outstanding Notes which has become due otherwise than by such
          declaration of acceleration, and interest on such unpaid principal at
          the rate borne by the Notes,

               (C)  to the extent that payment of such interest is lawful,
          interest on overdue interest at the rate borne by the Notes, and

               (D)  all sums paid or advanced by the Trustee hereunder and the
          reasonable compensation, fees, expenses, disbursements and advances of
          the Trustee, its agents and counsel and any amounts due the Trustee
          under Section 606;

          (2)  all Events of Default, other than the non-payment of amounts of
     principal of (or premium, if any, on) and accrued and unpaid interest and
     Liquidated Damages, if any, on the Notes which have become due solely by
     such declaration of acceleration, have been cured or waived as provided in
     Section 513; and

          (3)  the recission, in the Opinion of Counsel, would not conflict with
     any judgment or decrees of a court of competent jurisdiction.

No such rescission shall affect any subsequent default or impair any right
consequent thereon.

          Notwithstanding the preceding paragraph, in the event of a declaration
of acceleration in respect of the Notes because of an Event of Default specified
in Section 501(6) shall have occurred and be continuing, such declaration of
acceleration shall be automatically 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 the Company 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.

                        -------------------------------------------------------
Trustee.
- ------- 

          The Company covenants that if

          (a)  default is made in the payment of any installment of interest and
     Liquidated Damages, if any, on any Note when such interest becomes due and
     payable and such default continues for a period of 30 days, or

          (b)  default is made in the payment of the principal of (or premium,
     if any, on) any Note at the Maturity thereof,

                                      -50-
<PAGE>
 
the Company will pay to the Trustee for the benefit of the Holders of such
Notes, the whole amount then due and payable on such Notes for principal (and
premium and Liquidated Damages, if any) and interest, and interest on any
overdue principal (and premium, if any) and, to the extent that payment of such
interest shall be legally enforceable, upon any overdue installment of interest
and Liquidated Damages, if any, at the rate borne by the Notes, and, in addition
thereto, such further amount as shall be sufficient to cover the costs and
expenses of collection, including the reasonable compensation, fees expenses,
disbursements and advances of the Trustee, its agents and counsel and any
amounts due the Trustee under Section 606.

          If the Company fails to pay such amounts forthwith upon such demand,
the Trustee, in its own name as trustee of an express trust, may institute a
judicial proceeding for the collection of the sums so due and unpaid, may
prosecute such proceeding to judgment or final decree and may enforce the same
against the Company or any other obligor upon the Notes and collect the moneys
adjudged or decreed to be payable in the manner provided by law out of the
property of the Company or any other obligor upon the Notes, wherever situated.

          If an Event of Default occurs and is continuing, the Trustee may in
its discretion proceed to protect and enforce its rights and the rights of the
Holders by such appropriate judicial proceedings as the Trustee shall deem most
effectual to protect and enforce any such rights, whether for the specific
enforcement of any covenant or agreement in this Indenture or in aid of the
exercise of any power granted herein, or to enforce any other proper remedy.

          SECTION 504.  Trustee May File Proofs of Claim.

bankruptcy, reorganization, arrangement, adjustment, composition or other
judicial proceeding relative to the Company or any other obligor upon the Notes
or the property of the Company or of such other obligor or their creditors, the
Trustee (irrespective of whether the principal of the Notes shall then be due
and payable as therein expressed or by declaration or otherwise and irrespective
of whether the Trustee shall have made any demand on the Company for the payment
of overdue principal, premium, if any, interest or Liquidated Damages, if any)
shall be entitled and empowered, by intervention in such proceeding or
otherwise,

          (i)   to file and prove a claim for the whole amount of principal (and
     premium and Liquidated Damages, if any) and interest owing and unpaid in
     respect of the Notes and to file such other papers or documents as may be
     necessary or advisable in order to have the claims of the Trustee
     (including any claim for the reasonable compensation, fees, expenses,
     disbursements and advances of the Trustee, its agents and counsel and any
     amounts due the Trustee under Section 606) and of the Holders allowed in
     such judicial proceeding, and

          (ii)  to collect and receive any moneys or other property payable or
     deliverable on any such claims and to distribute the same;

                                      -51-
<PAGE>
 
and any custodian, receiver, assignee, trustee, liquidator, sequestrator or
similar official in any such judicial proceeding is hereby authorized by each
Holder to make such payments to the Trustee and, in the event that the Trustee
shall consent to the making of such payments directly to the Holders, to pay the
Trustee any amount due it for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other
amounts due the Trustee under Section 606.

          Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder any plan of
reorganization, arrangement, adjustment or composition affecting the Notes or
the rights of any Holder thereof, or to authorize the Trustee to vote in respect
of the claim of any Holder in any such proceeding.

          SECTION 505.  Trustee May Enforce Claims Without Possession of Notes.
                        ------------------------------------------------------ 

          All rights of action and claims under this Indenture or the Notes may
be prosecuted and enforced by the Trustee without the possession of any of the
Notes or the production thereof in any proceeding relating thereto, and any such
proceeding instituted by the Trustee shall be brought in its own name and as
trustee of an express trust, and any recovery of judgment shall, after provision
for the payment of the reasonable compensation, fees, expenses, disbursements
and advances of the Trustee, its agents and counsel, be for the ratable benefit
of the Holders of the Notes in respect of which such judgment has been
recovered.

surrender thereof if fully paid:

          FIRST: To the payment of all amounts due the Trustee under Section
     606;

     premium and Liquidated Damages, if any) and interest, respectively; and

          THIRD: The balance, if any, to the Person or Persons entitled
     thereto.

     to the Trustee against any costs, liability or expense;

          (4)  the Trustee does not comply with the request within 60 days after
     receipt of the request and the offer of indemnity; and

          (5)  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;

it being understood and intended that no one or more Holders shall have any
right in any manner whatever by virtue of, or by availing of, any provision of
this Indenture to affect, disturb or prejudice the rights of any other Holders,
or to obtain or to seek to obtain priority or preference over any other Holders
or to enforce any right under this Indenture, except in the manner herein
provided and for the equal and ratable benefit of all the Holders.

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

          If the Trustee or any Holder has instituted any proceeding to enforce

discontinued or abandoned for any reason, or has been determined adversely to
the Trustee or to such Holder, then and in every such case, subject to any
determination in such proceeding, the Company, the Trustee and the Holders shall

exercise any right or remedy accruing upon any Event of Default shall impair any
such right or remedy or constitute a waiver of any such Event of Default or an
acquiescence therein.  Every right and remedy given by this Article or by law to
the Trustee or to the Holders may be exercised from time to time, and as often
as may be deemed expedient, by the Trustee or by the Holders, as the case may
be.

          SECTION 512.  Control by Holders.

     each Outstanding Note affected.

          Upon any such waiver, such default shall cease to exist, and any Event
of Default arising therefrom shall be deemed to have been cured, for every
purpose of this Indenture; but no such waiver shall extend to any subsequent or
other default or Event of Default or impair any right consequent thereon.

          SECTION 514.  Waiver of Stay or Extension Laws.

performance of this Indenture; and the Company (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such law

     advances incurred or made by the Trustee in accordance with any provision
     of this Indenture (including the reasonable compensation and the expenses

acceptance of appointment by the successor Trustee in accordance with the
applicable requirements of Section 609.

          (b) The Trustee may resign at any time by giving written notice
thereof to the Company.  If the instrument of acceptance by a successor Trustee

petition any court of competent jurisdiction for the appointment of a successor
Trustee.

     fail to resign after written request therefor by the Company or by any
     Holder who has been a bona fide Holder of a Note for at least six months,
     or

          (3) the Trustee shall become incapable of acting or shall be adjudged
     a bankrupt or insolvent or a receiver of the Trustee or of its property

fide Holder of a Note for at least six months may, on behalf of himself and all
others similarly situated, petition any court of competent jurisdiction for the
removal of the Trustee and the appointment of a successor Trustee.

          (e) If the Trustee shall resign, be removed or become incapable of
acting, or if a vacancy shall occur in the office of Trustee for any cause, the
Company, by a Board Resolution, shall promptly appoint a successor Trustee.  If,
within one year after such resignation, removal or incapability, or the
occurrence of such vacancy, a successor Trustee shall be appointed by Act of the
Holders of a majority in principal amount of the Outstanding Notes delivered to
the Company and the retiring Trustee, the successor Trustee so appointed shall,
forthwith upon its acceptance of such appointment, become the successor Trustee
and supersede the successor Trustee appointed by the Company.  If no successor
Trustee shall have been so appointed by the Company or the Holders and accepted
appointment in the manner hereinafter provided, any Holder who has been a bona
fide Holder of a Note for at least six months may, on behalf of himself and all
others similarly situated, petition any court of competent jurisdiction for the
appointment of a successor Trustee.

Notes in the manner provided for in Section 106.  Each notice shall include the

          Every successor Trustee appointed hereunder shall execute, acknowledge
and deliver to the Company and to the retiring Trustee an instrument accepting
such appointment, and thereupon the resignation or removal of the retiring
Trustee shall become effective and such successor Trustee, without any further
act, deed or conveyance, shall become vested with all the rights, powers, trusts
and duties of the retiring Trustee; but, on request of the Company or the
successor Trustee, such retiring Trustee shall, upon payment of its charges,
execute and deliver an instrument transferring to such successor Trustee all the
rights, powers and trusts of the retiring Trustee and shall duly assign,
transfer and deliver to such successor Trustee all property and money held by
such retiring Trustee hereunder.  Upon request of any such successor Trustee,
the Company shall execute any and all instruments for more fully and certainly
vesting in and confirming to such successor Trustee all such rights, powers and
trusts.

          No successor Trustee shall accept its appointment unless at the time
of such acceptance such successor Trustee shall be qualified and eligible under
this Article.

business of the Trustee, shall be the successor of the Trustee hereunder,

Article, without the execution or filing of any paper or any further act on the

authenticated, but not delivered, by the Trustee then in office, any successor
by merger, conversion or consolidation to such authenticating Trustee may adopt
such authentication and deliver the Notes so authenticated with the same effect
as if such successor Trustee had itself authenticated such Notes.  In case at
that time any of the Notes shall not have been authenticated, any successor
Trustee may authenticate such Notes either in the name of any predecessor
hereunder or in the name of the successor Trustee.  In all such cases such
certificates shall have the full force and effect which this Indenture provides
for the certificate of authentication of the Trustee shall have; provided,

Company into any other corporation, or upon any conveyance, lease or transfer of

property or assets, secure the Notes Outstanding (together with, if the Company
shall so determine any other Indebtedness of the Company now existing or
hereinafter created which is not subordinate in right of payment to the Notes)

          SECTION 1003.  Money for Note Payments to Be Held in Trust.

     premium and Liquidated Damages, if any) or interest on Notes in trust for
     the benefit of the Persons entitled thereto until such sums shall be paid
     to such Persons or otherwise disposed of as herein provided;

          (2) give the Trustee notice of any default by the Company (or any
     other obligor upon the Notes) in the making of any payment of principal
     (and premium and Liquidated Damages, if any) or interest on the Notes; and

          (3) at any time during the continuance of any such default, upon the
     written request of the Trustee, forthwith pay to the Trustee all sums so

upon the same terms as those upon which such sums were held by the Company or
such Paying Agent; and, upon such payment by any Paying Agent to the Trustee,
such Paying Agent shall be released from all further liability with respect to
such sums.

become due and payable shall be paid to the Company on Company Request, or (if
then held by the Company) shall be discharged from such trust; and the Holder of
such Note shall thereafter, as an unsecured general creditor, look only to the
Company for payment thereof, and all liability of the Trustee or such Paying
Agent with respect to such trust money, and all liability of the Company as

expense of the Company cause to be published once, in a newspaper published in
the English language, customarily published on each Business Day and of general

          The Company will comply with Rule 14e-1 under the Exchange Act 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 the
Company is required to repurchase the Notes under this Section 1010.

          (a)    The Company will not, and will not permit any of its Restricted
Subsidiaries to, Incur any Indebtedness (other than the Notes); provided,

ratio of (i) the aggregate principal amount (or accreted value, as the case may
be) of Indebtedness of the Company 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, the Company 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 the Company 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 and (b) 65%

     ownership rights with respect to indefeasible rights of use or minimum
     investment units (or similar ownership interests) in domestic or

     case purchased or leased by the Company (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 of
     such equipment, ownership rights or minimum investment units so acquired);

     to be a Restricted Subsidiary or any subsequent transfer of such
     Indebtedness not permitted by this clause (iii) (other than to the Company
     or another Restricted Subsidiary) shall be deemed, in each case, to
     constitute the incurrence of such Indebtedness, and provided further that

     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

     case the Indebtedness to be refinanced is subordinated in right of payment

     agreement or instrument pursuant to which such new Indebtedness is issued
     or remains outstanding, is expressly made subordinate in right of

     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 Indebtedness of the

     Company, to the extent such Net Cash Proceeds have not been used pursuant
     to clause (C)(2) of the first paragraph or clauses (iii), (iv) and (vii) of
     the second paragraph of Section 1012 to make a Restricted Payment and (B)
     the Fair Market Value (as determined in good faith by the 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 the Company after the Closing Date from the issuance or sale of
     its Common Stock (other than Redeemable Stock) to a Person that is not a
     Subsidiary of the Company to the extent such sale of Common Stock has not
     been used pursuant to clauses (iii), (iv) and (vii) of the second paragraph
     of Section 1012; 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 the Company 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 the
     --------                                                            
     Company 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 obligations of the
     Company or any of its Restricted Subsidiaries pursuant to such agreements,
     in any case Incurred in connection with the disposition of any business,
     assets or Restricted Subsidiary of the Company (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

                                      -74-

     the gross proceeds actually received by the Company or any Restricted
     Subsidiary in connection with such disposition;

          (vii)  Indebtedness of the Company, 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 set
     forth in Article Thirteen;

          (viii) Indebtedness of a Restricted Subsidiary represented by a
     Guarantee of the Notes and any other Indebtedness of the Company permitted
     by and made in accordance with Section 1018;

          (ix)   Indebtedness of the Company or any Restricted Subsidiary not
     otherwise permitted hereunder in an aggregate principal amount, 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 the Company 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 Section 1011, the
maximum amount of this Indebtedness that the Company or a Restricted Subsidiary
may Incur pursuant to this Section 1011 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 Section 1011, 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 Section 1011, 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, the Company, in its 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.

principal payment, or voluntary or optional redemption, repurchase, defeasance,

     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

     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 Section 1011;

     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 Section 1011; provided that prior to
                                                         --------

     in such covenant with respect to the Notes and has 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.

          Each Restricted Payment permitted pursuant to the immediately
preceding paragraph (other than a Restricted Payment referred to in clause (ii)
thereof, and an exchange of Capital Stock for Capital Stock, Indebtedness or an
Investment referred to in clause (iii), (iv) or (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 Section 1012 have been met with respect to any
subsequent Restricted Payments.  In the event the proceeds of an issuance of
Capital Stock of the Company are used for the redemption, repurchase or other
acquisition of the Notes or Indebtedness that is pari passu with the Notes, then
                                                 ---- -----                     
the Net Cash Proceeds of such issuance shall be included in clause (C) of the
first paragraph of this Section 1012 only to the extent such proceeds are not
used for such redemption, repurchase or other acquisition of Indebtedness.

          SECTION 1013.  Limitation on Dividend and Other Payment Restrictions
                         -----------------------------------------------------
Affecting Restricted Subsidiaries.
- --------------------------------- 

          So long as any of the Notes are Outstanding, the Company 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 the Company or any other Restricted
Subsidiary, (ii) pay any Indebtedness owed to the Company or any other
Restricted Subsidiary, (iii) make loans or advances to the Company or any other
Restricted Subsidiary, or (iv) transfer any of its property or assets to the
Company or any other Restricted Subsidiary.

          The foregoing provisions shall not restrict any encumbrances or
restrictions:

                                      -78-
<PAGE>
 
          (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
     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 the Company) and the Company determines that any such
     encumbrance or restriction will not materially affect the Company's 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 the Company 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

     prevent the Company or any Restricted Subsidiary from (1) creating,
     incurring, assuming or suffering to exist any Liens otherwise permitted in
     Section 1016 or (2) restricting the sale or other disposition of property
     or assets of the Company or any of its Restricted Subsidiaries that secure

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

          The Company 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 the Company 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 (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 Section 1017, (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 Section

                          ------------------------------------------------
Affiliates.
- ---------- 

          The Company 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 of the
Company or with any Affiliate of the Company or any Restricted Subsidiary,
unless:

          (i) such transaction or series of transactions is on terms no less
     favorable to the Company 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 the Board of Directors of the
     Company, including the approval of a majority of the independent,
     disinterested directors, and is evidenced by a resolution of the Board of
     Directors of the Company, and

          (iii)  if such transaction or series of transactions involves
     aggregate consideration in excess of $25.0 million, then the Company or
     such Restricted Subsidiary will deliver to the Trustee a written opinion as
     to the fairness to the Company 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 the

                                      -80-
<PAGE>
 
     Company 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 the Board of Directors of the Company, including
     a majority of the independent disinterested directors, and are evidenced by
     a resolution of the Board of Directors of the Company.

          The foregoing limitation does not limit, and will not apply to (i) any
transaction between the Company and any of its Restricted Subsidiaries or
between Restricted Subsidiaries; (ii) the payment of reasonable and customary
regular fees to directors of the Company who are not employees of the Company;
(iii) any Restricted Payments not prohibited by Section 1012; (iv) transactions
provided for in the Employment Agreement as in effect on the Closing Date; and
(v) loans and advances to employees of the Company 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 1016.  Limitation on Liens.
                         ------------------- 

          Under the terms of the Indenture, the Company 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 its 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 1017.  Limitation on Asset Sales.
                         ------------------------- 

          The Company will not, and will, not permit any Restricted Subsidiary
to, make any Asset Sale unless (i) the Company 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 the Board of Directors,
which determination, in each case where such fair market value is greater than
$5.0 million, shall 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.

          The Company 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 unsubordinated Indebtedness of the Company or Indebtedness of
any Restricted Subsidiary, in each case owing to a Person other than the Company
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, the
Company and its Restricted Subsidiaries existing on the date of such investment
(as determined in good faith

                                      -81-
<PAGE>
 
by the 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
Section 1017.  The amount of such Net Cash Proceeds required to be applied (or
to be committed to be applied) during such 360-day period in the manner as set
forth in clause (i) of 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, the Company 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").

          The Company 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
     Section 1017 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 the Company defaults 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" 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

                                      -82-
<PAGE>
 
     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 upon Company Order, 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.
     The Company will publicly announce the results of the Excess Proceeds Offer
     as soon as practicable after the Excess Proceeds Payment Date.  For
     purposes of this Section 1017, the Trustee shall act as the Paying Agent.

          The Company will comply with Rule 14e-1 under the Exchange Act 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 Section 1017 and the Company is required to repurchase
Notes as described above.

          SECTION 1018.  Limitation on Issuances of Guarantees of Indebtedness
                         -----------------------------------------------------
by Restricted Subsidiaries.
- -------------------------- 

          The Company will not permit any Restricted Subsidiary, directly or
indirectly, to guarantee, assume or in any other manner become liable with
respect to any Indebtedness of the Company, other than Indebtedness under Credit
Facilities incurred under clauses (i) and (ii) of Section 1011, 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

                                      -83-
<PAGE>
 
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 or reimbursement, indemnity or
subrogation or any other rights against the Company 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 the Company, of all of the Company's 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 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 1019.  Business of the Company.
                         ------------------------

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

          SECTION 1020.  Limitation on Investments in Unrestricted
                         -----------------------------------------
Subsidiaries.
- -------------

          The Company will not make, and will not permit any of its 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 Section 1012.  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 the Board of Directors of the Company
(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 1021.  Waiver of Certain Covenants.
                         --------------------------- 

          The Company may omit in any particular instance to comply with any
term, provision or condition set forth in Section 803 or Sections 1007 through
1020, inclusive, if before or after the time for such compliance the Holders of
at least a majority in principal amount of the Outstanding Notes, by Act of such
Holders, waive such compliance in such instance with such term, provision or
condition, but no such waiver shall extend to or affect such term, provision or
condition except to the extent so expressly waived, and, until such waiver shall
become effective, the obligations of the Company and the duties of the Trustee
in respect of any such term, provision or condition shall remain in full force
and effect.

          SECTION 1101.  Right of Redemption.
                         ------------------- 

          (a) The Notes may be redeemed, at the election of the Company, as a
whole or from time to time in part, at any time after May 15, 2003, subject to
the conditions and at the Redemption Prices specified in the form of Note,
together with accrued interest to the Redemption Date.

          (b) Notwithstanding the foregoing, prior to May 15, 2001, the Company
may redeem up to 25% of the originally issued aggregate principal amount of the
Notes on one or more occasions with the Net Cash Proceeds of one or more Public
Equity Offerings at a redemption price equal to 109.875% of the aggregate
principal amount thereof, plus accrued interest, if any, 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); provided that, immediately after giving effect to such
                        --------                                              
redemption, at least 75% of the originally issued aggregate principal amount of
the Notes remains Outstanding; and provided further that notice of such
                                   -------- -------                    
redemptions shall be given within 60 days of the date of closing of any such
Public Equity Offering.

          SECTION 1102.  Applicability of Article.

permitted or required by any provision of this Indenture, shall be made in
accordance with such provision and this Article.

          SECTION 1103.  Election to Redeem; Notice to Trustee.
                         ------------------------------------- 

          The election of the Company to redeem any Notes pursuant to Section
1101 shall be evidenced by a Board Resolution.  In case of any redemption at the
election of the Company, the Company shall, at least 60 days prior to the
Redemption Date fixed by the Company (unless a shorter notice shall be
satisfactory to the Trustee), notify the Trustee of such Redemption Date and of
the principal amount of Notes to be redeemed and shall deliver to the Trustee
such documentation and records as shall enable the Trustee to select the Notes
to be redeemed pursuant to Section 1104.

          SECTION 1104.  Selection by Trustee of Notes to Be Redeemed.
                         -------------------------------------------- 

          If less than all the Notes are to be redeemed, the particular Notes to
be redeemed shall be selected not more than 60 days prior to the Redemption Date
by the Trustee, from the Outstanding Notes not previously called for redemption,
in compliance with the requirements of the principal

                                      -85-
<PAGE>
 
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 method as the Trustee shall deem fair and appropriate and which
may provide for the selection for redemption of portions of the principal of
Notes; provided, however, that no such partial redemption shall reduce the
       --------  -------                                                  
portion of the principal amount of a Note not redeemed to less than $1,000.

          The Trustee shall promptly notify the Company in writing of the Notes
selected for redemption and, in the case of any Notes selected for partial
redemption, the principal amount thereof to be redeemed.

          For all purposes of this Indenture, unless the context otherwise
requires, all provisions relating to redemption of Notes shall relate, in the
case of any Note redeemed or to be redeemed only in part, to the portion of the
principal amount of such Note which has been or is to be redeemed.

          SECTION 1105.  Notice of Redemption.
                         --------------------

          (1) the Redemption Date,

          (2) the Redemption Price and the amount of accrued interest to the
     Redemption Date payable as provided in Section 1107, if any,

          (3) if less than all Outstanding Notes are to be redeemed, the
     identification (and, in the case of a partial redemption, the principal
     amounts) of the particular Notes to be redeemed,

          (4) in case any Note is to be redeemed in part only, the notice which
     relates to such Note shall state that on and after the Redemption Date,
     upon surrender of such Note, the Holder will receive, without charge, a new
     Note or Notes of authorized denominations for the principal amount thereof
     remaining unredeemed,

          (5) that on the Redemption Date the Redemption Price (and accrued
     interest and Liquidated Damages, if any, to the Redemption Date payable as
     provided in Section 1107) will become due and payable upon each such Note,
     or the portion thereof, to be redeemed, and that interest thereon will
     cease to accrue on and after said date,

          (6) the place or places where such Notes are to be surrendered for
     payment of the Redemption Price and accrued interest and Liquidated
     Damages, if any.

          Prior to any Redemption Date, the Company shall deposit with the
Trustee or with a Paying Agent (or, if the Company is acting as its own Paying
Agent, segregate and hold in trust as provided in Section 1003) an amount of
money sufficient to pay the Redemption Price of, and Liquidated Damages, if any,
and accrued interest on, all the Notes which are to be redeemed on that date.

          SECTION 1107.  Notes Payable on Redemption Date.
                         -------------------------------- 

          Notice of redemption having been given as aforesaid, the Notes so to
be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified (together with Liquidated Damages and accrued
interest, if any, to the Redemption Date), and from and after such date (unless
the Company shall default in the payment of the Redemption Price and accrued
interest) such Notes shall cease to bear interest.  Upon surrender of any such
Note for redemption in accordance with said notice, such Note shall be paid by
the Company at the Redemption Price, together with Liquidated Damages and
accrued interest, if any, to the Redemption Date; provided, however, that
                                                  --------  -------      
installments of interest whose Stated Maturity is on or prior to the Redemption
Date shall be payable to the Holders of such Notes, or one or more Predecessor
Notes, registered as such at the close of business on the relevant Record Dates
according to their terms and the provisions of Section 309.

          If any Note called for redemption shall not be so paid upon surrender
thereof for redemption, the principal (and premium, if any) shall, until paid,
bear interest from the Redemption Date at the rate borne by the Notes.

          SECTION 1108.  Notes Redeemed in Part.
                         ---------------------- 

          Any Note which is to be redeemed only in part (pursuant to the
provisions of this Article) shall be surrendered at the office or agency of the
Company maintained for such purpose pursuant to Section 1002 (with, if the
Company or the Trustee so requires, due endorsement by, or a written instrument
of transfer in form satisfactory to the Company and the Trustee duly executed
by, the Holder thereof or such Holder's attorney duly authorized in writing),
and the Company shall execute, and the Trustee shall upon Company Order
authenticate and deliver to the Holder of such Note without service charge, a
new Note or Notes, of any authorized denomination as requested by such Holder,
in aggregate principal amount equal to and in exchange for the unredeemed
portion of the principal of the Note so surrendered.

                               ARTICLE THIRTEEN

                      DEFEASANCE AND COVENANT DEFEASANCE

          SECTION 1301.  Company's Option to Effect Defeasance or Covenant
                         -------------------------------------------------
Defeasance.
- ---------- 

          The Company may, at its option by Board Resolution, at any time, with
respect to the Notes, elect to have either Section 1302 or Section 1303 be
applied to all Outstanding Notes upon compliance with the conditions set forth
below in this Article Thirteen.

          SECTION 1302.  Defeasance and Discharge.
                         ------------------------ 

          Upon the Company's exercise under Section 1301 of the option
applicable to this Section 1302, the Company shall be deemed to have been
discharged from its obligations with respect to all Outstanding Notes on the
date the conditions set forth in Section 1304 are satisfied (hereinafter,
"defeasance").  For this purpose, such defeasance means that the Company shall
be deemed to have paid and discharged the entire indebtedness represented by the
Outstanding Notes, which shall thereafter be deemed to be "Outstanding" only for
the purposes of Section 1305 and the other Sections of this Indenture referred
to in (A) and (B) below, and to have satisfied all its other obligations under
such Notes and this Indenture insofar as such Notes are concerned (and the
Trustee, at the expense of the Company, shall execute proper instruments
acknowledging the same), except for the following which shall survive until
otherwise terminated or discharged hereunder: (A) the rights of Holders of
Outstanding Notes to receive, solely from the trust fund described in Section
1304 and as more fully set forth in such Section, payments in respect of the
principal of (and premium, if any, on) and interest and Liquidated Damages, if
any, on such Notes when such payments are due, (B) the Company's obligations
with respect to such Notes under Sections 304, 305, 308, 1002 and 1003, (C) the
rights, powers, trusts, duties and immunities of the Trustee hereunder and (D)
this Article Thirteen.  Subject to compliance with this Article Thirteen, the
Company may exercise its option under this Section 1302 notwithstanding the
prior exercise of its option under Section 1303 with respect to the Notes.

          SECTION 1303.  Covenant Defeasance.
                         ------------------- 

          Upon the Company's exercise under Section 1301 of the option
applicable to this Section 1303, the Company shall be released from its
obligations under any covenant contained in Section 801(3) and Section 803 and
in Sections 1007 through 1021 with respect to the Outstanding

                                      -88-
<PAGE>
 
Notes on and after the date the conditions set forth below are satisfied
(hereinafter, "covenant defeasance"), and the Notes shall thereafter be deemed
not to be "Outstanding" for the purposes of any direction, waiver, consent or
declaration or Act of Holders (and the consequences of any thereof) in
connection with such covenants, but shall continue to be deemed "Outstanding"
for all other purposes hereunder.  For this purpose, such covenant defeasance
means that, with respect to the Outstanding Notes, the Company may omit to
comply with and shall have no liability in respect of any term, condition or
limitation set forth in any such covenant, whether directly or indirectly, by
reason of any reference elsewhere herein to any such covenant or by reason of
any reference in any such covenant to any other provision herein or in any other
document and such omission to comply shall not constitute a Default or an Event
of Default under Section 501(5), but, except as specified above, the remainder
of this Indenture and such Notes shall be unaffected thereby.

          SECTION 1304.  Conditions to Defeasance or Covenant Defeasance.
                         ----------------------------------------------- 

          The following shall be the conditions to application of either Section
1302 or Section 1303 to the Outstanding Notes:

          (1) The Company shall irrevocably have deposited or caused to be
     deposited with the Trustee (or another trustee satisfying the requirements
     of Section 607 who shall agree to comply with the provisions of this
     Article Thirteen applicable to it) as trust funds in trust for the purpose
     of making the following payments, specifically pledged as security for, and
     dedicated solely to, the benefit of the Holders of such Notes, (A) cash in
     United States dollars, or (B) U.S. Government Obligations which through the
     scheduled payment of principal and interest in respect thereof in
     accordance with their terms will provide, not later than one day before the
     due date of any payment, money in an amount, or (C) a combination thereof,
     sufficient, in the opinion of a nationally recognized firm of independent
     public accountants expressed in a written certification thereof delivered
     to the Trustee, to pay and discharge, and which shall be applied by the
     Trustee (or other qualifying trustee) to pay and discharge, (i) the
     principal of (and premium, if any), interest and Liquidated Damages, if
     any, on the Outstanding Notes on the Stated Maturity (or Redemption Date,
     if applicable) of such principal (and premium, if any) or installment of
     interest and Liquidated Damages, if any, and (ii) any mandatory sinking
     fund payments or analogous payments applicable to the Outstanding Notes on
     the day on which such payments are due and payable in accordance with the
     terms of this Indenture and of such Notes; provided that the Trustee shall
                                                --------                       
     have been irrevocably instructed to apply such money or the proceeds of
     such U.S. Government Obligations to said payments with respect to the
     Notes.  Before such a deposit, the Company may give to the Trustee, in
     accordance with Section 1103 hereof, a notice of its election to redeem all
     of the Outstanding Notes at a future date in accordance with Article Eleven
     hereof, which notice shall be irrevocable.  Such irrevocable redemption
     notice, if given, shall be given effect in applying the foregoing.  For
     this purpose, "U.S. Government Obligations" means securities that are (x)
     direct obligations of the United States of America for the timely payment
     of which its full faith and credit is pledged or (y) obligations of a
     Person controlled or supervised by and acting as an agency or
     instrumentality of the United States of America

                                      -89-
<PAGE>
 
     the timely payment of which is unconditionally guaranteed as a full faith
     and credit obligation by the United States of America, which, in either
     case, are not callable or redeemable at the option of the issuer thereof,
     and shall also include a depository receipt issued by a bank (as defined in
     Section 3(a)(2) of the Securities Act of 1933, as amended), as custodian
     with respect to any such U.S. Government Obligation or a specific payment
     of principal of or interest on any such U.S. Government Obligation held by
     such custodian for the account of the holder of such depository receipt,
     provided that (except as required by law) such custodian is not authorized
     --------                                                                  
     to make any deduction from the amount payable to the holder of such
     depository receipt from any amount received by the custodian in respect of
     the U.S. Government Obligation or the specific payment of principal of or
     interest on the U.S. Government Obligation evidenced by such depository
     receipt.

          (2) No Default or Event of Default with respect to the Notes shall
     have occurred and be continuing on the date of such deposit or, insofar as
     paragraphs (8) and (9) of Section 501 hereof are concerned, at any time
     during the period ending on the 123rd day after the date of such deposit
     (it being understood that this condition shall not be deemed satisfied
     until the expiration of such period).

          (3) [Reserved]

          (4) Such defeasance or covenant defeasance shall not result in a
     breach or violation of, or constitute a default under any material
     agreement or instrument (other than this Indenture) to which the Company is
     a party or by which it is bound.

          (5) In the case of an election under Section 1302, the Company shall
     have delivered to the Trustee an Opinion of Counsel stating that (x) the
     Company has received from, or there has been published by, the Internal
     Revenue Service a ruling, or (y) since May 14, 1998, there has been a
     change in the 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.

          (6) In the case of an election under Section 1303, the Company shall
     have delivered to the Trustee an Opinion of Counsel to the effect that the
     Holders of the Outstanding Notes 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.

          (7) The Company 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

                                      -90-
<PAGE>
 
     either the defeasance under Section 1302 or the covenant defeasance under
     Section 1303 (as the case may be) have been complied with.

          SECTION 1305.  Deposited Money and U.S. Government Obligations to Be
                         -----------------------------------------------------
Held in Trust; Other Miscellaneous Provisions.
- --------------------------------------------- 

          Subject to the provisions of the last paragraph of Section 1003, all
money and U.S. Government Obligations (including the proceeds thereof) deposited
with the Trustee (or other qualifying trustee, collectively for purposes of this
Section 1305, the "Trustee") pursuant to Section 1304 in respect of the
Outstanding Notes shall be held in trust and applied by the Trustee, in
accordance with the provisions of such Notes and this Indenture, to the payment,
either directly or through any Paying Agent (including the Company acting as its
own Paying Agent) as the Trustee may determine, to the Holders of such Notes of
all sums due and to become due thereon in respect of principal (and premium and
Liquidated Damages, if any) and interest, but such money need not be segregated
from other funds except to the extent required by law.

          The Company shall pay and indemnify the Trustee against any tax, fee
or other charge imposed on or assessed against the U.S. Governmental Obligations
deposited pursuant to Section 1304 or the principal and interest received in
respect thereof other than any such tax, fee or other charge which by law is for
the account of the Holders of the Outstanding Notes.

          Anything in this Article Thirteen to the contrary notwithstanding, the
Trustee shall deliver or pay to the Company from time to time upon Company
Request any money or U.S. Government Obligations held by it as provided in
Section 1304 which, in the opinion of a nationally recognized firm of
independent public accountants expressed in a written certification thereof
delivered to the Trustee, are in excess of the amount thereof which would then
be required to be deposited to effect an equivalent defeasance or covenant
defeasance, as applicable, in accordance with this Article.

          SECTION 1306.  Reinstatement.
                         ------------- 

          If the Trustee or any Paying Agent is unable to apply any money in
accordance with Section 1305 by reason of any order or judgment of any court or
governmental authority enjoining, restraining or otherwise prohibiting such
application, then the Company's obligations under this Indenture and the Notes
shall be revived and reinstated as though no deposit had occurred pursuant to
Section 1302 or 1303, as the case may be, until such time as the Trustee or
Paying Agent is permitted to apply all such money in accordance with Section
1305; provided, however, that if the Company makes any payment of principal of
      --------  -------                                                       
(or premium or Liquidated Damages, if any) or interest on any Note following the
reinstatement of its obligations, the Company shall be subrogated to the rights
of the Holders of such Notes to receive such payment from the money held by the
Trustee or Paying Agent.

                                      -91-

          This Indenture may be signed in any number of counterparts each of
which so executed shall be deemed to be an original, but all such counterparts
shall together constitute but one and the same Indenture.

be duly executed as of the day and year first above written.

          Primus Telecommunications Group, Incorporated, a Delaware corporation
(herein called the "Company," which term includes any successor Person under the
Indenture hereinafter referred to), for value received, hereby promises to pay
to _________ or registered assigns, the principal sum of ___________ United
States dollars on May 15, 2008, at the office or agency of the Company referred
to below, and to pay interest thereon on November 15, 1998 and semi-annually
thereafter, on May 15 and November 15 in each year, from May 19, 1998 or from
the most recent Interest Payment Date to which interest has been paid or duly
provided for, at the rate of 97/8% per annum, until the principal hereof is paid
or duly provided for, and (to the extent lawful) to pay on demand interest on
any overdue interest at the rate borne by the Notes from the date on which such
overdue interest becomes payable to the date payment of such interest has been
made or duly provided for.  The interest so payable, and punctually paid or duly
provided for, on any Interest Payment Date will, as provided in such Indenture,
be paid to the Person in whose name this Note (or one or more Predecessor Notes)
is registered at the close of business on the Regular Record Date for such

and (to the extent lawful) interest on such defaulted interest at the rate borne
by the Notes, may be paid to the Person in whose name this Note (or one or more
Predecessor Notes) is registered at the close of business on a Special Record

purpose without being succeeded within five Business Days by a post-effective
amendment to such Registration Statement that cures such failure and that is
declared effective within such five Business Day period (each such event
referred to in clauses (i) through (iv) above, a "Registration Default"),
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 the
Company 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 (as defined in the Registration Rights
Agreement), the accrual of Liquidated Damages with respect to such Transfer
Restricted Notes will cease.]**

          Payment of the principal of (and premium and Liquidated Damages, if
any) and interest on this Note will be made at the office or agency of the
Company maintained for that purpose in The City of New York, or at such other
office or agency of the Company as may be maintained for such purpose, in such
coin or currency of the United States of America as at the time of payment is
legal tender for payment of public and private debts; provided, however, that

                           9 7/8% Senior Notes Due 2008

          This Note is one of a duly authorized issue of notes of the Company
designated as its 9 7/8% Senior Notes Due 2008 (herein called the "Notes"),
limited (except as otherwise provided in the Indenture referred to below) in
aggregate principal amount to $150,000,000, which may be issued under an

which term includes any successor trustee under the Indenture), to which
Indenture and all indentures supplemental thereto reference is hereby made for a
statement of the respective rights, limitations of rights, duties, obligations
and immunities thereunder of the Company, the Trustee and the Holders of the
Notes, and of the terms upon which the Notes are, and are to be, authenticated
and delivered.

          The Notes are subject to redemption upon not less than 30 nor more
than 60 days prior notice, in whole or in part, at any time or from time to time
on or after May 15, 2003 and prior to Maturity, at the election of the Company,

     result of which it is necessary, in the opinion of counsel for you or

      ------------
     purchasers of Notes designated by such holders, upon request of such

     pursuant to the Exchange Act or any rule or regulation of the Commission
     thereunder.

          (f)  Promptly from time to time to take such action as the Initial
     Purchasers may reasonably request to qualify the Notes for offering and
     sale under the securities laws of such jurisdictions as the Initial

     continuance of sales and dealings therein in such jurisdictions for as long
     as may be necessary to complete the distribution of the Notes; provided,
     however, that in no event shall the Company be obligated to qualify to do
     business in any jurisdiction where it is not now so qualified or to take
     any action which would subject it to service of process in suits, other
     than those suits arising out of the offering or sale of the Notes, in any
     jurisdiction where it is not now so subject. In each jurisdiction in which
     the Notes have been so qualified, the Company will file such statements and

     such qualification in effect for a period of not less than one year from
     the effective date of the Registration Statement. The Company will also

     conversion, exchange or exercise of securities outstanding on the date of
     this Agreement, without the consent of Lehman Brothers (which consent will
     not be unreasonably withheld) during the period beginning from the date of
     this Agreement and continuing for 180 days following the Closing Date.

(including, but not limited to, any loss, claim, damage, liability or action
relating to purchases and sales of Notes), to which such Initial Purchaser,
officer, director or controlling person may become subject, under the Securities
Act or otherwise, insofar as such loss, claim, damage, liability or action

statement of a material fact contained in (A) the Preliminary Memorandum, the

fact required to be stated therein or necessary to make the statements therein
in light of the circumstances in which they were made not misleading or (iii)
any act or failure to act, or any alleged act or failure to act, by any Initial
Purchaser in connection with, or relating in any manner to, the Notes or the
offering contemplated hereby, and which is included as part of or referred to in
any loss, claim, damage, liability or action arising out of or based upon
matters covered by clause (i) or (ii) above (provided that the Company and the
Principal Subsidiaries shall not be liable in the case of any matter covered by
this clause (iii) to the extent that it is determined in a final judgment by a
court of competent jurisdiction that such loss, claim, damage, liability or
action resulted directly from any such act or failure to act undertaken or
omitted to be taken by such Initial Purchaser through its gross negligence or
wilful misconduct), and shall reimburse each Initial Purchaser and each such
officer, director or controlling person promptly upon demand for any legal or
other expenses reasonably incurred by that Initial Purchaser, officer, director
or controlling person in connection with investigating or defending or preparing
to defend against any such loss, claim, damage, liability or action as such
expenses are incurred upon written submission to the Company of documentation
evidencing such incurrence; provided, however, that the Company and the

any such loss, claim, damage, liability or action arises out of, or is based
upon, any untrue statement or alleged untrue
<PAGE>
 
                                       20

statement or omission or alleged omission made in the Preliminary Memorandum,
the Memorandum or in any such amendment or supplement, or in any Blue Sky
Application in reliance upon and in conformity with the written information
concerning such Initial Purchaser furnished to the Company by or on behalf of
any Initial Purchaser specifically for inclusion therein; provided further that
as to the Preliminary Memorandum, this indemnity agreement shall not inure to
the benefit of any Initial Purchaser or any officer, director or controlling
person of that Initial Purchaser on account of any loss, claim, damage,
liability or action arising from the sale of Notes to any person by such Initial
Purchaser if (i) such Initial Purchaser failed to send or give a copy of the
Memorandum, as the same may be amended or supplemented, to that person within
the time required by the Securities Act and (ii) the untrue statement or alleged
untrue statement of a material fact or omission or alleged omission to state a
material fact in the Preliminary Memorandum was corrected in the Memorandum or a
supplement or amendment thereto, as the case may be, unless in each case, such
failure resulted from noncompliance by the Company with Section 5(c). The
foregoing indemnity agreement is in addition to any liability which the Company
may otherwise have to any Initial Purchaser or to any officer, director or
controlling person of that Initial Purchaser.

               (b)   Each Initial Purchaser, severally and not jointly, shall
indemnify and hold harmless the Company, its directors and officers, and each
person, if any, who controls the Company within the meaning of Section 15 of the
Securities Act, from and against any loss, claim, damage or liability, joint or
several, or any action in respect thereof, to which the Company or any such
director, officer or controlling person may become subject, under the Securities
Act or otherwise, insofar as such loss, claim, damage, liability or action
arises out of, or is based upon, (i) any untrue statement or alleged untrue
statement of a material fact contained in (A) the Preliminary Memorandum, the
Memorandum or in any amendment or supplement thereto or (B) any Blue Sky
Application or (ii) the omission or alleged omission to state in the Preliminary
Memorandum, the Memorandum or in any amendment or supplement thereto, or in any
Blue Sky Application any material fact required to be stated therein or
necessary to make the statements therein in light of the circumstances in which
they were made not misleading, but in the case of clauses (i) and (ii) only to
the extent that the untrue statement or alleged untrue statement or omission or
alleged omission was made in reliance upon and in conformity with the written
information concerning such Initial Purchaser furnished to the Company or the
Trustee by or on behalf of that Initial Purchaser specifically for inclusion
therein, and shall reimburse the Company and any such director, officer or
controlling person for any legal or other expenses reasonably incurred by the
Company or any such director, officer or controlling person in connection with
investigating or defending or preparing to defend against any such loss, claim,
damage, liability or action as such expenses are incurred. The foregoing
indemnity agreement is in addition to any liability which any Initial Purchaser
may otherwise have to the Company or any such director, officer or controlling
person.

               (c)   Promptly after receipt by an indemnified party under this
Section 9 of notice of any claim or the commencement of any action, the
indemnified party shall, if a claim in
<PAGE>
 
                                       21

respect thereof is to be made against the indemnifying party under this Section
9, notify the indemnifying party in writing of the claim or the commencement of
that action; provided, however, that the failure to notify the indemnifying
party shall not relieve it from any liability which it may have under this
Section 9 except to the extent the indemnifying party has been materially
prejudiced by such failure and provided further that the failure to notify the
indemnifying party shall not affect any liability which it may have to an
indemnified party otherwise than under this Section 9. If any such claim or
action shall be brought against an indemnified party, and it shall notify the
indemnifying party thereof, the indemnifying party shall be entitled to
participate therein and, to the extent that it wishes, jointly with any other
similarly notified indemnifying party, to assume the defense thereof with
counsel reasonably satisfactory to the indemnified party. After notice from the
indemnifying party to the indemnified party of its election to assume the
defense of such claim or action, the indemnifying party shall not be liable to
the indemnified party under this Section 9 for any legal or other expenses
subsequently incurred by the indemnified party in connection with the defense
thereof other than reasonable costs of investigation; provided, however, that
the indemnified party shall have the right to employ separate counsel to
represent jointly the indemnified party and its respective directors, officers
and controlling persons who may be subject to liability arising out of any claim
in respect of which indemnity may be sought by the indemnified party against the
indemnifying party under this Section 9 if such indemnified party shall have
been advised in writing that the representation of such indemnified party and
those directors, officers, and controlling persons by the same counsel would be
inappropriate under applicable standards of professional conduct due to actual
or potential differing interests between them, and in that event the fees and
expenses of such separate counsel shall be paid by the indemnifying party. It is
understood that the indemnifying party shall not be liable for the fees and
expenses of more than one separate firm (in addition to local counsel in each
jurisdiction) for all indemnified parties in connection with any proceeding or
related proceedings. Each indemnified party, as a condition of the indemnity
agreements contained in Sections 9(a) and 9(b), shall use its best efforts to
cooperate with the indemnifying party in the defense of any such action or
claim. No indemnifying party shall (i) without the prior written consent of the
indemnified parties (which consent shall not be unreasonably withheld), settle
or compromise or consent to the entry of any judgment with respect to any
pending or threatened claim, action, suit or proceeding in respect of which
indemnification or contribution may be sought hereunder (whether or not the
indemnified parties are actual or potential parties to such claim or action)
unless such settlement, compromise or consent includes an unconditional release
of each indemnified party from all liability arising out of such claim, action,
suit or proceeding, or (ii) be liable for any settlement of any such action
effected without its written consent (which consent shall not be unreasonably
withheld), but if settled with its written consent or if there be a final
judgment in favor of the plaintiff in any such action, the indemnifying party
agrees to indemnify and hold harmless any indemnified party from and against any
loss of liability by reason of such settlement or judgment in accordance with
this Section 9.

                                       22

               (d)   If the indemnification provided for in this Section 9 shall
for any reason be unavailable to or insufficient to hold harmless an indemnified
party under Section 9(a) or 9(b) in respect of any loss, claim, damage or
liability, or any action in respect thereof, referred to therein, then each
indemnifying party shall, in lieu of indemnifying such indemnified party,
contribute to the amount paid or payable by such indemnified party as a result
of such loss, claim, damage or liability, or action in respect thereof, (i) in
such proportion as shall be appropriate to reflect the relative benefits
received by the Company and the Principal Subsidiaries, on the one hand, and the
Initial Purchasers, on the other hand, from the offering of the Notes or (ii) if
the allocation provided by clause (i) above is not permitted by applicable law,
in such proportion as is appropriate to reflect not only the relative benefits
referred to in clause (i) above but also the relative fault of the Company and
the Principal Subsidiaries, on the one hand, and the Initial Purchasers, on the
other hand, with respect to the statements or omissions which resulted in such
loss, claim, damage or liability, or action in respect thereof, as well as any
other relevant equitable considerations. The relative benefits received by the
Company and the Principal Subsidiaries, on the one hand, and the Initial
Purchasers, on the other hand, with respect to such offering shall be deemed to
be in the same proportion as the total net proceeds from the offering of the
Notes purchased under this Agreement (before deducting expenses) received by the
Company, on the one hand, and the total underwriting commissions and discounts
received by the Initial Purchasers with respect to the Notes purchased under
this Agreement, on the other hand, bear to the total gross proceeds from the
offering of the Notes under this Agreement, in each case as set forth in the
table on the cover page of the Memorandum. The relative fault shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or omission or alleged omission to state a
material fact relates to information supplied by the Company and the Principal
Subsidiaries, on the one hand, or the Initial Purchasers, on the other hand, the
intent of the parties and their relative knowledge, access to information and
opportunity to correct or prevent such statement or omission. Each of the
Company and the Principal Subsidiaries and the Initial Purchasers agrees that it
would not be just and equitable if contribution pursuant to this Section 9(d)
were to be determined by pro rata allocation (even if either the Initial
Purchasers or the Company and the Principal Subsidiaries, as the case may be,
were treated as one entity for such purpose) or by any other method of
allocation which does not take into account the equitable considerations
referred to herein. The amount paid or payable by an indemnified party as a
result of the loss, claim, damage or liability, or action in respect thereof,
referred to above in this Section 9(d) shall be deemed to include, subject to
limitations set forth above, any legal or other expenses reasonably incurred by
such indemnified party in connection with investigating or defending any such
action or claim. Notwithstanding the provisions of this Section 9(d), no Initial
Purchaser shall be required to indemnify or contribute any amount in excess of
the amount by which the proceeds received by the Initial Purchasers from an
offering of the Notes exceeds the amount of any damages which such Initial
Purchaser has otherwise paid or become liable to pay by reason of any untrue or
alleged untrue statement or omission or alleged omission. No person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation. The
<PAGE>
 
                                       23

remedies provided for in this Section 9 are not exclusive and shall not limit
any rights or remedies which may otherwise be available to any indemnified party
at law or in equity. The Initial Purchasers' obligations to contribute as
provided in this Section 9(d) are several in proportion to their respective
underwriting obligations and not joint.

               (e)   Each of the Initial Purchasers confirms and the Company
acknowledges that (1) the last paragraph on the cover page, (2) the
stabilization legend on page (ii), and (3) the fifth paragraph, the sixth
paragraph, the sixth sentence of the ninth paragraph and the first sentence of
the tenth paragraph under the caption "Plan of Distribution" constitute the only
information concerning the Initial Purchasers furnished in writing to the
Company by or on behalf of the Initial Purchasers specifically for inclusion in
the Memorandum.

               10.   Default by Any Initial Purchaser. If, on the Closing Date,
any Initial Purchaser or Initial Purchasers shall fail or refuse to purchase
Notes which it or they have agreed to purchase hereunder on such date and the
aggregate principal amount of Notes with respect to which such default occurs is
more than one-tenth of the aggregate principal amount of Notes to be purchased
on such date and arrangements satisfactory to the Initial Purchasers and the
Company for the purchase of such Notes are not made within 36 hours after such
default, this Agreement shall terminate without liability on the part of any 
non-defaulting Initial Purchaser or of the Company. In any such case, either
you, on the one hand, or the Company, on the other hand, shall have the right to
postpone the Closing Date, but in no event for longer than seven days, in order
that the required changes, if any, in the Memorandum or in any other documents
or arrangements may be effected. Any action taken under this paragraph shall not
relieve any defaulting Initial Purchaser from liability in respect of any
default of such Initial Purchaser under this Agreement.

               11.   Termination. The obligations of the Initial Purchasers
hereunder may be terminated by them by notice given to and received by the
Company prior to delivery of and payment for the Notes if, prior to that time,
(i) trading in securities generally on the New York Stock Exchange or the
American Stock Exchange or in the over-the-counter market shall have been
suspended or minimum prices shall have been established on any such exchange or
such market by the Commission, by such exchange or by any other regulatory body
or governmental authority having jurisdiction, (ii) a banking moratorium shall
have been declared by federal or New York State authorities, (iii) the United
States shall have become engaged in hostilities, there shall have been an
escalation in hostilities involving the United States or there shall have been a
declaration of a national emergency or war by the United States or (iv) there
shall have occurred such a material adverse change in general economic,
political or financial conditions (or the effect of international conditions on
the financial markets in the United States shall be such) as to make it, in the
judgment of the Initial Purchasers, impracticable or inadvisable to proceed with
the offering or delivery of the Notes on the terms and in the manner
contemplated in the Memorandum.

                                       24

               12.   Reimbursement of Initial Purchaser's Expenses. If the sale
of Notes provided for herein is not consummated because any condition to the
obligations of the Initial Purchasers set forth in Section 8 hereof is not
satisfied, because of any refusal, inability or failure on the part of the
Company to perform any agreement herein or comply with any provision hereof
other than by reason of a default by the Initial Purchasers, the Company shall
reimburse the Initial Purchasers for the reasonable fees and expenses of its
counsel and for such other out-of-pocket expenses as shall have been incurred by
them in connection with this Agreement and the proposed purchase of the Notes,
and upon demand the Company shall pay the full amount thereof to the Initial
Purchasers. If this Agreement is terminated pursuant to Section 10 by reason of
the default of any of the Initial Purchasers, the Company shall not be obligated
to reimburse any Initial Purchaser on account of those expenses.

               13.   Notices, Etc. All statements, requests, notices and
agreements hereunder shall be in writing, and:

               (a)   if to the Initial Purchasers, shall be delivered or sent by
     mail or facsimile transmission to:

               14.   Persons Entitled to Benefit of Agreement. This Agreement
shall inure to the benefit of and be binding upon the Initial Purchasers, the
Company, and their respective successors. This Agreement and the terms and
provisions hereof are for the sole benefit of only those persons, except that
(x) the representations, warranties, indemnities and agreements of the Company
contained in this Agreement shall also be deemed to be for the benefit of the
officers and directors of the Initial Purchasers and the person or persons, if
any, who control the Initial Purchasers within the meaning of Section 15 of the
Securities Act and (y) the representations, warranties, indemnities and
agreements of the Initial Purchasers contained in this Agreement shall be deemed
to be for the benefit of directors and officers of the Company and any person
controlling the Company within the meaning of Section 15 of the Securities Act.
Nothing in this Agreement is intended or shall be construed to give any person,
other than the persons referred to
<PAGE>
 
                                       25

in this Section 14, any legal or equitable right, remedy or claim under or in
respect of this Agreement or any provision contained herein.

               15.   Survival. The respective indemnities, representations,
warranties and agreements of the Company, on the one hand, and the Initial
Purchasers, on the other hand, contained in this Agreement or made by or on
behalf of them, respectively, pursuant to this Agreement, shall survive the
delivery of and payment for the Notes and shall remain in full force and effect,
regardless of any investigation made by or on behalf of any of them or any
person controlling any of them.

               16.   Definition of the Term "Business Day." For purposes of this
Agreement, "business day" means any day on which the New York Stock Exchange,
            ------------                                                     
Inc. is open for trading.

               17.   GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY AND
CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

               18.   Consent to Jurisdiction. Each party irrevocably agrees that

proceedings instituted in regard to the enforcement of a judgment of any such
court (a "Related Judgment"), as to which such jurisdiction is non-exclusive) of
such courts in any such suit, action or proceeding. The parties further agree
that service of any process, summons, notice or document by mail to such party's
address set forth above shall be effective service of process for any lawsuit,
action or other proceeding brought in any such court. The parties hereby
irrevocably and unconditionally waive any objection to the laying of venue of
any lawsuit, action or other proceeding in the Specified Courts, and hereby
further irrevocably and unconditionally waive and agree not to plead or claim in
any such court that any such lawsuit, action or other proceeding brought in any
such court has been brought in an inconvenient forum. Primus Telecommunications
(Australia) Pty. Ltd. hereby irrevocably appoints CT Corporation System, which
currently maintains a New York City office at 1633 Broadway, New York, New York

other legal summons for purposes of any such action or proceeding that may be
instituted in any state or federal court in the City and State of New York.

               19.   Waiver of Immunity. With respect to any Related Proceeding,
each party irrevocably waives, to the fullest extent permitted by applicable
law, all immunity (whether on the basis of sovereignty or otherwise) from
jurisdiction, service of process, attachment (both before and after judgment)
and execution to which it might otherwise be entitled in the Specified
<PAGE>
 
                                       26

Courts, and with respect to any Related Judgment, each party waives any such
immunity in the Specified Courts or any other court of competent jurisdiction,

Lehman Brothers Inc.
   as Representative of the Initial Purchasers
   named in Schedule 1 to the Purchase Agreement
   referred to below
Three World Financial Center
New York, New York  10285

          Re:  Primus Telecommunications Group, Incorporated
               ---------------------------------------------

Ladies and Gentlemen:

          Based upon the foregoing assumptions, and subject to the
qualifications set forth below, we are of the opinion that:

          (i)    The Company and each of its U.S. subsidiaries have been duly
incorporated and are validly existing as corporations in good standing under the
laws of their respective jurisdictions of incorporation, are duly qualified to
do business and are in good standing as foreign corporations in each
jurisdiction in which their respective ownership or lease of property or the
conduct of their respective businesses requires such qualification (except where
the failure to so qualify, singly or in the aggregate, would not have a material
adverse effect on the consolidated financial position, stockholders' equity,
results of operations or business of the Company and its subsidiaries taken as a
whole), and have all power and authority necessary to own or hold their
respective properties and conduct the businesses in which they are engaged.

          (ii)   The Company has an authorized capitalization as set forth in
the Memorandum, and all of the issued shares of capital stock of the Company
have been duly and validly authorized and issued, are fully paid and non-
assessable; and all of the issued shares of capital stock of each U.S.
subsidiary of the Company have been duly and validly authorized and issued and
are fully paid, non-assessable and (except for directors' qualifying shares and
except as set forth in the Memorandum) are owned of record and, to the best of
our knowledge, beneficially directly or indirectly by the Company, free and
clear of all liens, encumbrances, equities or claims.
 
          (iii)  To the best of our knowledge, there are no legal or
governmental proceedings pending to which the Company or any of the subsidiaries
of the Company is a party or of which any property or assets of the Company or
any of the subsidiaries of the Company is the subject
<PAGE>
 
                                      A-2

which, if determined adversely to the Company or any of its subsidiaries, might
have a material adverse effect on the consolidated financial position,
stockholders' equity, results of operations or business of the Company and the
subsidiaries of the Company or on the ability of the Company to perform its
obligations under the Purchase Agreement, the Indenture, the Registration Rights
Agreement or the Notes; and, to the best of our knowledge, no such proceedings
are threatened by governmental authorities or others.


          (iv)   To the best of our knowledge, there are no contracts or other
documents which would be required to be described in the Memorandum by the
Securities Act or by the Rules and Regulations, if the Memorandum were a
Registration Statement on Form S-1, which have not been described in the
Memorandum.

          (v)    To the best of our knowledge, there are no statutes or
regulations that would be required to be described in the Memorandum, if the
Memorandum, were a Registration Statement on Form S-1, that are not described as
required.

          (vi)   The Purchase Agreement and the TresCom Merger Agreement have
been duly authorized, executed and delivered by the Company and PTI.

          (vii)  The execution and delivery of the Notes have been duly
authorized by all necessary corporate action of the Company, and the Notes, when
executed and authenticated in accordance with the provisions of the Indenture
and paid for in accordance with the Purchase Agreement, will (x) constitute
valid, binding and enforceable obligations of the Company, enforceable in
accordance with their terms, except as the enforceability thereof may be limited
by bankruptcy, insolvency, reorganization, fraudulent conveyance or transfer,
moratorium, liquidation or similar laws affecting the rights and remedies of
creditors and other obligees generally and except as may be subject to general
principles of equity (regardless of whether enforcement is sought in a
proceeding in equity or at law) and (y) be entitled to the benefits of the
Indenture.

          (viii) The Registration Rights Agreement has been duly authorized,
executed and delivered by the Company and PTI and constitutes a valid and
binding agreement of the Company and PTI, enforceable against the Company and
PTI in accordance with its terms, except as such enforceability may be limited
by bankruptcy, insolvency, fraudulent conveyance or transfer, reorganization,
liquidation, moratorium or other similar laws affecting the rights and remedies
of creditors and other obligees generally and except as may be subject to
general principles of equity (regardless of whether enforcement is sought in a
proceeding in equity or at law), and except as rights to indemnity and
contribution thereunder may be limited by applicable law and public policy.

          (ix)   The Indenture has been duly authorized, executed and delivered
by the Company and, assuming due authorization, execution and delivery thereof
by the Trustee,
<PAGE>
 
                                      A-3

constitutes a valid and legally binding agreement of the Company enforceable in
accordance with its terms, except as the enforceability thereof may be limited
by applicable bankruptcy, insolvency, reorganization, fraudulent conveyance or
transfer, moratorium, liquidation or other similar laws affecting the rights and
remedies of creditors and other obligees generally or by general principles of
equity (regardless of whether enforcement is sought in a proceeding in equity or
at law).

          (x)    The issue and sale of the Notes being delivered on the Closing
Date by the Company, the compliance by the Company with all of the provisions of
the Purchase Agreement, the Registration Rights Agreement and the Indenture and
the consummation of the transactions contemplated hereby and thereby, will not
result in a material breach or violation of any of the terms or provisions of,
or constitute a default under, (i) any indenture, mortgage, deed of trust, loan
agreement or other agreement or instrument known to such counsel to which the
Company or any of the subsidiaries of the Company is a party or by which the
Company or any of the subsidiaries of the Company is bound or to which any of
the property or assets of the Company or any of the subsidiaries of the Company

Ladies and Gentlemen:

          Based upon and limited to such examination and subject to the
assumptions and qualifications set forth in this letter, it is our opinion as of
the date hereof that:

          (i)   (A) The execution and delivery of the Purchase Agreement by the
Company and the issue and sale of the Notes contemplated thereby do not violate
(1) the Communications Act, (2) any rules or regulations of the FCC applicable
to the Company and/or to PTI, (3) any State Telecommunications Laws applicable
to the Company and/or to PTI, and (4) to the best of our knowledge, any decree
from any court, and (B) no authorization of or filing with the FCC or any State
Regulatory Agency is necessary for the execution and delivery of the Purchase
Agreement by the Company and the issue and sale of the Notes contemplated
thereby in accordance with the terms thereof;

          (ii)  PTI is a nondominant carrier authorized by the FCC to provide
domestic interstate interexchange telecommunications services pursuant to 47
C.F.R. (S) 63.07(a) (1996) without any further order, license, permit or other
authorization by the FCC.  PTI has been granted Section 214 authority by the FCC
to provide international message telecommunications services and private line
services through the resale of international switched voice and private line
services and/or by using its own facilities and has on file with the FCC tariffs
applicable to its domestic interstate and international services;

          (iii) PTI is certified, registered or otherwise authorized, or is not
required to obtain authority to resell intrastate interexchange
telecommunications services in all U.S. states except Hawaii and Alaska.  PTI
has a tariff on file in each of the states in which a tariff is required to be
filed;

          (iv)  (A) PTI (1) to the best of our knowledge has made all reports
and filings, and paid all fees, required by the FCC and the State Regulatory
Agencies except for those reports and filings the failure to file of which, and
those fees the failure to pay of which, would not have a

material adverse effect on the financial condition, the earnings, business or
operations of PTI; and (2) based on our understanding of PTI's operations from
the Certificate, has all certificates, orders, permits, licenses,
authorizations, consents and approvals of and from (the "Authorizations"), and
has made all filings and registrations with, the FCC and the State Regulatory
Agencies necessary to own, lease, license and use its properties and assets and
to conduct its business in the manner described in the Memorandum except for
those Authorizations the failure to obtain of which, and those filings and
registrations the failure to file of which, would not have a material adverse
effect on the financial condition, or the earnings, business or operations of
PTI; and (B) to the best of our knowledge, PTI has not received any notice of
proceedings relating to the revocation or modification of any such certificates,
orders, permits, licenses, authorizations, consents or approvals, or the
qualification or rejection of any such filing or registration, the effect of
which, singly or in the aggregate, would have a material adverse effect on the
financial condition, the earnings, business or operations of the Company and its
subsidiaries taken as a whole;

          (v)   Based on our understanding of PTI's operations from the
Certificate, neither the Company nor PTI is in violation of, or in default under
the Communications Act or State Telecommunications Laws, the effect of which,
singly or in the aggregate, would have a material adverse effect on the
financial condition, the earnings, business or operations of the Company and its
subsidiaries taken as a whole;

          (vi)  To the best of our knowledge (A) as of the date hereof, no
decree or order of the FCC or any State Regulatory Agency is outstanding against
the Company or any of its subsidiaries and (B) except as set forth in the
Certificate, no litigation, proceeding, inquiry or investigation has been
commenced or threatened and no notice of violation or order to show cause has
been issued, against the Company or any of its subsidiaries before or by the FCC
or any State Regulatory Agency; and

          (vii) The statements in the Memorandum under the captions "Risk
Factors -Potential Adverse Effects of Regulation - United States" and "Business
- - Government Regulation - United States," insofar as such statements constitute
a summary of the legal matters, documents or proceedings of the FCC and State
Regulatory Agencies with respect to telecommunications regulation referred to
therein, are accurate in all material respects and fairly summarize all such
matters referred to therein.

          The opinions expressed in this letter are subject in all respects to
the following qualifications:  (1) this opinion speaks only to the transactions
that are being consummated on the date hereof and does not address any
transaction that may take place after the Closing Date; (2) any action that
would transfer de facto or de jure legal control of PTI is subject to the
               -- -----    -- ----                                       
requirement for prior approval from the FCC and/or State Regulatory Agencies;
(3) no opinion is rendered as to matters not specifically referred to herein or
to events which have not yet occurred and under no circumstances are you to
infer from anything stated or not stated herein any opinion
<PAGE>
 
                                      B-3

with respect to such matters; and (4) all opinions expressed in this letter are
limited solely to the effect of the Communications Act and State
Telecommunications Laws on the telecommunications business of the Company and
PTI and we express no opinion as to the effect of any other federal or state
statute or equitable doctrine or common law or of the regulations of any other
agency or administrative body.

          Other than as expressly stated in paragraphs one (i) through seven
(vii), no opinion is rendered as to the compliance of PTI in the past or in the
future with any or all conditions or other requirements of the FCC and the State
Regulatory Agencies contained in the orders, if any, authorizing the operations
of the Company or PTI or otherwise imposed by statute, rule, regulation or
policy, and we assume no obligation to ensure that the Company or PTI comply
with such conditions or requirements.  We are admitted to the District of
Columbia Bar and, with respect to any matters concerning the law of the States,
we draw your attention to the fact that the members of the firm involved in the
preparation of this opinion letter, although generally familiar with the
telecommunications laws of the States, are not admitted to the Bars of the
States and are not experts in the laws of those jurisdictions.

Ladies and Gentlemen:

          We have acted as special Canadian counsel to Primus Telecommunications
Group, Incorporated, a Delaware corporation ("Primus"), in connection with the
execution and delivery by Primus of the Purchase Agreement dated May __, 1998

As to matters of fact relevant to the opinions herein expressed, we have assumed

          Primus Canada has been duly incorporated and is validly existing as a
     corporation in good standing under the laws of [ ___________ ], is duly
     qualified to do business and is in good standing in each jurisdiction in
     which its ownership or lease of property or the conduct of its respective
     businesses require such qualification (except where the failure to so
     qualify, singly or in the aggregate, would not have a material adverse
     effect on the financial position, stockholders' equity, results of
     operations or business of Cam-Net), and has all power and authority
     necessary to own or hold its respective properties and conduct the
     businesses in which they are engaged.

                [LETTERHEAD OF BRUCKHAUS WESTRICK HELLER LOBER]


We are of the opinion that:

(1)  the descriptions in the Preliminary Offering Memorandum given under the
captions "Risk Factors - Potential Adverse Effects of the Regulation -Germany"
and "Business - Government Regulation - Germany" of the German
Telecommunications Act of July 25, 1996 and the respective rules and regulations
promulgated thereunder (collectively, the "German Telecommunications Law") are
accurate in all material respects and fairly summarize all matters described
therein; we advise you, however, that the German Regulator's interpretation of
the German Telecom Act as well as its complementing ordinances may be subject to
material changes which can presently not be predicted in content or scope. More
specifically, the German Regulator has already indicated repeatedly that it may
want to start differentiating between facilities-based telecom operators and
switch-based resellers with regard to the applicable interconnection rates
(possibly reserving the provisionally approved interconnection rates of
September 1997 to facilities-based operators) and with regard to the catchment
areas for origination services (possibly restricting these to local area codes
around the points of interconnection). This regulatory change may become
effective only for the future but may also apply ex nunc or even retroactively
and may potentially require Primus to invest more heavily into network structure
and/or pay higher interconnection prices. Also, several issues have been brought
before the competent courts or may be pending due to ongoing regulatory
proceedings launched by third parties. This applies, in particular, to the
German Regulator's regulation of interconnection rates of September 1997 for the
years 1998-99 which is under court review and which may result in higher prices
being found to be applicable by the courts. According to the current
interconnection agreement with Deutsche Telekom these would apply retroactively
to all telecommunication services provided to Primus Germany by Deutsche Telekom
AG since the inception of services thereunder; its is, however, unclear whether
this retroactive effect stipulated in the interconnection agreement would
sustain court scrutiny.

(2)  Primus Germany is the holder of a license of license class 4 issued by the
German Regulator dated February 17, 1998 under Section 8 in connection with
Section 6 para. 2 no. 2 of the German Telecommunications Act of 1996, relating
to the provision of voice telephony services on the basis of self-operated
telecommunications networks in Germany;

(3)  (A) German Telecommunications law does not regulate the issuing of debt
instruments by telecommunications operators active within the German
jurisdiction or their parent companies; (B) no authorization of or filing with
the German Regulator is necessary for the execution and delivery of the Purchase
Agreement by the Company and the consummation of the transactions (including,
without limitation, issuance of the Notes and execution of the Indenture and the
<PAGE>
 
                                      H-2

Registration Rights--Agreement) contemplated thereby in accordance with the
terms thereof; we advise you, however, that, should the Purchase Agreement or
other agreements connected therewith allow for conversion of the senior notes
into shares of the Company and should such conversion lead to a change of
control, then such change of control would have to be filed with the German
Regulator and, as the case may be, with the Federal Cartel Office.

(4)  (A) To our knowledge and with the exceptions reported hereafter, Primus
Germany has all certificates, orders, permits, licenses, authorizations,
consents and approvals necessary to own, lease, license and use its properties
and assets and to conduct its business in the manner described in the
Preliminary Offering Memorandum; and (B) to our knowledge Primus Germany has not
received any notice of proceedings relating to the revocation or modification of
any such certificates, orders, permits, licenses, authorizations, consents or
approvals, or the qualification or rejection of any such filing or registration,
the effect of which, singly or in the aggregate, would have a material adverse
effect on the prospects, condition, financial or otherwise, or in the earnings,
business or operations of the Company and its subsidiaries, taken as a whole; we
advise you, however, that (i) the German Regulator may change requirements for a
license class 4 and Primus Germany may, therefore, in the future be required to
extend its current license and may have to pay additional license fees; (ii)
Primus Germany's use of the business name "Primus" itself as well as its use of
the name in its business dealings with third parties or for describing its
services products is challenged in a pending name and trademark dispute raised
by Metro Vermogensverwaltung GmbH & Co. KG and its wholly-owned subsidiary
Primus Digital TV GmbH on March 26, 1998, based on the identical name element
"Primus" (in the case of Primus Digital TV GmbH) as well as on two separate
trademarks "Primus" registered for neighboring business sectors (in the case of
Metro Vermogensverwaltung GmbH & Co. KG) and for business fields including
telecommunication services (in the case of Primus Digital TV GmbH). As a
consequence of this trademark dispute Primus may be forced to relinquish the
element "Primus" as part of its German company name and in its business dealings
with third parties.

(5)  to our knowledge, (A) Primus Germany is conducting its business in
accordance with the license of license class 4 issued by the German Regulator on
February 17, 1998; and (B) Primus Germany is not in violation of or in default
under the German Telecommunications Law, the effect of which, singly or in the
aggregate, would have a material adverse effect on the prospects, condition,
financial or otherwise, or on the earnings, business or operations of the
Company and its subsidiaries, taken as a whole; and

(6)  to our knowledge, (A) no decree or order of the German Regulator has been
issued against Primus Germany; (B) no litigation, proceeding, inquiry or
investigation has been commenced or threatened, and no notice of violation or
order to show cause has been issued, against Primus Germany before or by
_____________________ we advise you, however, that Deutsche Telekom AG has
reserved itself in the interconnection agreement with Primus Germany the
unilateral right to apply to the German Regulator with regard to the questions
(i) whether Primus Germany's network structure, in particular the number and
locations of points of
<PAGE>
 
                                      H-3

interconnection with Deutsche Telekom AG, entitles Primus Germany to
interconnection as defined by Section 35 German Telecom Act and (ii) whether it
entitles Primus Germany to the switching of calls originating Germany-wide; the
result of such regulatory proceeding if launched until May 31, 1998 wold be a
contractually founded claim by Deutsche Telekom AG to amend the interconnection
agreement in accordance with the German Regulator's ruling and, thus could
potentially require additional investments into points of
interconnection/switching facilities and/or the payment of higher
interconnection prices and/or a geographical restriction of Primus Germany's
switching of originating calls.

General Qualifications

         interconnection agreement with Deutsche Telekom AG), we are not
         involved in Primus Germany's day-to-day business operations and are,
         therefore, not fully informed of the current state of Primus Germany's
         business activities. This applies in particular to the effects of the
         Telepassport/USFI Acquisition (transfer of German customer base to
         Primus Germany), to Primus Germany's re-origination (call back) service
         activities and carrier wholesale service activities.

     (b) This opinion is confined to German law in force at the date hereof and
         as currently applied by German courts and the German Regulator; and we
         do not express or imply an opinion as to matters other than under
         German law. We assume no obligation to advise you of facts,
         circumstances, events or legal developments which hereafter may be
         brought to our attention and which may alter, affect of modify the

Registration Statement under the Securities Act relating to the Exchange Notes
and the Exchange Offer, (ii) use its reasonable best efforts to cause such
Registration Statement to become effective no later than 120 days after the
Closing Date, (iii) in connection with the foregoing, (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) if applicable, file a post-
effective amendment to such Registration Statement pursuant to Rule 430A under
the Securities Act and (C) cause all necessary filings in connection with the
registration and qualification of the Exchange Notes to be made under the "blue
sky" laws of such jurisdictions as are necessary to permit consummation of the
Exchange Offer, (iv) use its reasonable best efforts to cause the Exchange Offer
to be consummated on the earliest practicable date after the Exchange Offer
Registration Statement has become effective, but in no event later than 30 days
thereafter and (v) deliver the Exchange Notes in the same aggregate principal
amount as the aggregate principal amount of Transfer Restricted Securities that
were validly tendered by Holders thereof pursuant to the Exchange Offer.  The
Exchange Offer shall be on the appropriate form permitting registration of the
Exchange Notes to be offered in exchange for the Transfer Restricted Securities
and to permit resales of Exchange Notes held by Broker-Dealers as contemplated
by Section 3(c) below.  The time periods referred to in clauses (i), (ii) and
(iv) of this Section 3(a) shall not include any period during which the Company
is pursuing a Commission ruling pursuant to Section 6(a)(i) below.

          (b)  Consummation of the Exchange Offer.  The Company shall use its
               ----------------------------------                            
reasonable best efforts to cause the Exchange Offer Registration Statement to be
effective continuously and shall keep the Exchange Offer open for a period of
not less than the minimum period required under applicable federal and state
securities laws to consummate the Exchange Offer; provided, however, that in no
event shall such period be less than 20 business days.  The Company shall cause
the Exchange Offer to comply in all material respects with all applicable
federal and state securities laws.  No securities other than the Exchange Notes
shall be included in the Exchange Offer Registration Statement.  The Exchange
Offer shall not be subject to any conditions, other than that the Exchange Offer
does not violate applicable law or any applicable interpretation of the
Commission.  The Company shall inform the Initial Purchasers of the names and
addresses of the Holders to whom the Exchange Offer is made, and the Initial
Purchasers shall have the right, subject to applicable law and at its own
expense, to contact such Holders and otherwise facilitate the tender of Transfer
Restricted Securities in the Exchange Offer.

          (c)  "Plan of Distribution" Section of the Prospectus.  The Company
               ------------------------------------------------              
shall indicate in a "Plan of Distribution" section contained in the Prospectus
contained in the Exchange Offer Registration Statement that any Broker-Dealer
who holds Notes that are Transfer Restricted Securities and that were acquired
for its own account as a result of market-making activities or other trading
activities (other than Transfer Restricted Securities acquired directly from the
Company), may exchange such Notes pursuant to the Exchange Offer; provided,
however, such Broker-Dealer may be deemed to be an "underwriter" within the
meaning of the Securities Act and must, therefore, deliver a prospectus meeting
the requirements of the

                                      -4-
<PAGE>
 
Securities Act in connection with any resales of the Exchange Notes received by
such Broker-Dealer in the Exchange Offer, which prospectus delivery requirement
may be satisfied by the delivery by such Broker-Dealer of the Prospectus
contained in the Exchange Offer Registration Statement.  Such "Plan of
Distribution" section shall also contain all other information with respect to
such resales by Broker-Dealers that the Commission may require in order to
permit such resales pursuant thereto, but such "Plan of Distribution" shall not
name any such Broker-Dealer or disclose the amount of Exchange Notes held by any
such Broker-Dealer except to the extent required by the Commission.

          The Company shall use its reasonable best efforts to keep the Exchange
Offer Registration Statement continuously effective, supplemented and amended as
required by the provisions of Section 6(c) below to the extent necessary (i) to
ensure that it is available for resales of Exchange Notes acquired by Broker-
Dealers for their own accounts as a result of market-making activities or other
trading activities, and (ii) to ensure that it conforms with the requirements of
this Agreement, the Securities Act and the policies, rules and regulations of
the Commission as announced from time to time in each case, for a period of 180
days from the date on which the Exchange Offer Registration Statement is
declared effective.

          The Company shall provide sufficient copies of the latest version of
such Prospectus to Broker-Dealers promptly upon their reasonable request at any
time during such 180-day period in order to facilitate such resales.

          4.   Shelf Registration.

          (a)  Shelf Registration.  If (i) the Company is not permitted to file
               ------------------

because the Exchange Offer is not permitted by applicable law or Commission
policy (after the procedures set forth in Section 6(a) below have been complied
with), (ii) any Holder of Transfer Restricted Securities that is a "qualified
institutional buyer" (as defined in Rule 144A under the Securities Act) shall
notify the Company at least 20 business days prior to the consummation of the
Exchange Offer (A) that such Holder is prohibited by applicable law or
Commission policy from participating in the Exchange Offer, or (B) that such
Holder may not resell the Exchange Notes acquired by it in the Exchange Offer to
the public without delivering a prospectus and that the Prospectus contained in
the Exchange Offer Registration Statement is not appropriate or available for
such resales by such Holder, or (C) that such Holder is a Broker-Dealer and
holds Notes acquired directly from the Company or one of its affiliates, (iii)
the Exchange Offer is not for any other reason consummated by October 16, 1998
or (iv) the Exchange Offer has been completed and in the 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, then the Company shall in lieu of or, in
the event of (ii) and (iv) above, in addition to effecting the registration of
the Exchange Notes pursuant to the Exchange Offer Registration Statement, use
its reasonable best efforts to:

                                      -5-
<PAGE>
 
          (x)  cause to be filed a shelf registration statement pursuant to Rule
     415 under the Securities Act which may be an amendment to the Exchange
     Offer Registration Statement (in either event, the "Shelf Registration
     Statement"), within 60 days of the earliest to occur of (1) the date on
     which the Company determines that it is not required to file the Exchange
     Offer Registration Statement, (2) the date on which the Company receives
     notice from a Holder of Transfer Restricted Securities as contemplated by
     clause (ii) above, (3) October 16, 1998 or (4) the receipt by the Company
     of the opinion of counsel contemplated by clause (iv) above (the 60th day
     following the earliest to occur of (1) through (4) being hereinafter
     referred to as the "Shelf Filing Deadline"), which Shelf Registration
     Statement shall provide for resales of all Transfer Restricted Securities
     for which the Holders of such Transfer Restricted Securities shall have
     provided the information required pursuant to Section 4(b) hereof; and

          (y)  cause such Shelf Registration Statement to be declared effective
     by the Commission on or before the 120th day after the Shelf Filing
     Deadline.

The Company shall use its reasonable best efforts to keep such Shelf
Registration Statement continuously effective, supplemented and amended as
required by the provisions of Sections 6(b) and (c) hereof to the extent
necessary (i) to ensure that it is available for resales of Notes by the Holders
of Transfer Restricted Securities entitled to the benefit of this Section 4(a),
and (ii) to ensure that such Shelf Registration Statement conforms and continues
to conform with the requirements of this Agreement, the Securities Act and the
policies, rules and regulations of the Commission, as announced from time to
time, in each case, for a period ending on the second anniversary of the Closing
Date.

          (b)  Provision by Holders of Certain Information in Connection with
               --------------------------------------------------------------
the Shelf Registration Statement. No Holder of Transfer Restricted Securities
- --------------------------------
may include any of its Transfer Restricted Securities in any Shelf Registration
Statement pursuant to this Agreement unless and until such Holder furnishes to
the Company in writing, within 10 business days after receipt of a request
therefor, such information as the Company may reasonably request for use in
connection with any Shelf Registration Statement or Prospectus or preliminary
prospectus included therein. No Holder of Transfer Restricted Securities shall
be entitled to Liquidated Damages pursuant to Section 5 hereof unless and until
such Holder shall have provided all such reasonably requested information within
the time period prescribed in this Section 4(b). Each Holder as to which any
Shelf Registration Statement is being effected agrees to notify the Company
promptly if any of the information previously furnished is misleading or
inaccurate in any material respect and to furnish promptly to the Company all
information required to be disclosed in order to make the information previously
furnished to the Company by such Holder not materially misleading or inaccurate.

          (c)  Declaring Effective the Exchange Offer Registration Statement. An
               -------------------------------------------------------------  
Exchange Offer Registration Statement pursuant to Section 3(a) hereof or a Shelf
Registration Statement pursuant to Section 4(a) hereof will not be deemed to
have become effective unless it has been declared effective by the Commission;
provided, however, that if, after it has been declared effective, the offering
of Transfer Restricted Securities pursuant to a Shelf Registration Statement is
interfered with by any stop order, injunction or other order or requirement of
the Commission or any other governmental agency or court, such Registration
Statement will be deemed not to have become effective during the period of such
interference until the offering of Transfer Restricted Securities pursuant to
such Registration Statement may legally resume.

          (d)  Failure of the Company to Comply with its Obligations.  Without
               -----------------------------------------------------          
limiting the remedies available to the Initial Purchasers and the Holders, the
Company acknowledges that any failure by the Company to comply with its
obligations under Section 3(a) and Section 4(a) hereof may result in material
irreparable injury to the Initial Purchasers or the Holders for which there is
no adequate remedy at law, that it will not be possible to measure damages for
such injuries precisely and that, in the event of any such failure, the Initial
Purchasers or any Holder may obtain such relief as may be required to
specifically enforce the Company's obligations under Section 3(a) and Section
4(a) hereof.

          5.   Liquidated Damages.

          (a)  Accrual and Amount of Liquidated Damages.  If (i) any of the
               ----------------------------------------                    
Registration Statements required by this Agreement is not filed with the
Commission on or prior to the date specified for such filing in this Agreement,
(ii) any of such Registration Statements has not been declared effective by the
Commission on or prior to the date specified for such effectiveness as set forth
in Section 3(a)(ii) and 4(a)(y) of this Agreement (the "Effectiveness Target
Date"), (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 this Agreement is filed
and declared effective but shall thereafter cease to be effective or fail 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 declared effective within such five business day
period (each such event referred to in clauses (i) through (iv), a "Registration
Default"), 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 shall be paid to
Holders by the Company in the same manner as interest is paid pursuant to the
Indenture.  Immediately upon 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.

                                      -7-
<PAGE>
 
          All obligations of the Company set forth in the preceding paragraph
that have accrued and are outstanding with respect to any Transfer Restricted
Security at the time such security ceases to be a Transfer Restricted Security
shall survive until such time as all such obligations with respect to such
Transfer Restricted Security shall have been satisfied in full.

          (b)  Notification of the Trustee. The Company shall notify the Trustee
               ---------------------------  
promptly after each and every date on which an event occurs in respect of which
Liquidated Damages are required to be paid (an "Event Date").  Liquidated
Damages shall be paid by depositing Liquidated Damages with the Trustee, in
trust, for the benefit of the Holders of the Notes, on or before the applicable
Interest Payment Date (whether or not any payment other than Liquidated Damages
is payable on such Notes), in immediately available funds in sums sufficient to
pay the Liquidated Damages then due to such Holders.  Each obligation to pay
Liquidated Damages shall be deemed to accrue from the applicable date of the
occurrence of the Registration Default.

          6.   Registration Procedures.

          (a)  Exchange Offer Registration Statement.  In connection with the
               -------------------------------------                         
Exchange Offer, the Company shall comply with all of the provisions of Section
6(c) below and shall use its reasonable best efforts to effect such exchange to
permit the sale of Transfer Restricted Securities being sold in accordance with
the intended method or methods of distribution thereof. In addition, the Company
(with respect to (i) and (iii) of this Section 6(a)) and each Holder of Transfer
Restricted Securities (with respect to (ii) of this Section 6(a)) shall comply
with the following provisions:

          (i)  If in the reasonable opinion of counsel to the Company there is a
     question as to whether the Exchange Offer is permitted by applicable law,
     the Company hereby agrees to seek a no-action letter or other favorable
     decision from the Commission allowing the Company to consummate an Exchange
     Offer for such Notes.  The Company hereby agrees to pursue the issuance of
     such a decision to the Commission staff level but shall not be required to
     take commercially unreasonable action to effect a change of Commission
     policy.  The Company hereby agrees, however, to (A) participate in
     telephonic conferences with the staff of the Commission, (B) deliver to the
     Commission staff an analysis prepared by counsel to the Company setting
     forth the legal bases, if any, upon which such counsel has concluded that
     such an Exchange Offer should be permitted and (C) use reasonable best
     efforts pursue a resolution (which need not be favorable) by the Commission
     staff of such submission.

          (ii) As a condition to its participation in the Exchange Offer
     pursuant to the terms of this Agreement, each Holder of Transfer Restricted
     Securities shall (x) furnish, upon the request of the Company, prior to the
     consummation thereof, a written representation to the Company (which may be
     contained in the letter of transmittal contemplated by the Exchange Offer
     Registration Statement) to the effect that (A) it is

                                      -8-
<PAGE>
 
     not an affiliate of the Company, (B) it is not engaged in, and does not
     intend to engage in, and has no arrangement or understanding with any
     person to participate in, a distribution of the Exchange Notes to be issued
     in the Exchange Offer and (C) it is acquiring the Exchange Notes in its
     ordinary course of business and (y) otherwise cooperate in the Company's
     preparations for the Exchange Offer.  Each Holder hereby acknowledges and
     agrees that any Broker-Dealer and any such Holder using the Exchange Offer
     to participate in a distribution of the securities to be acquired in the
     Exchange Offer (1) could not under Commission policy as in effect on the
     date of this Agreement rely on the position of the Commission enunciated in
     Morgan Stanley and Co., Inc. (available June 5, 1991) and Exxon Capital
     ----------------------------                              -------------

     no-action letters (including Brown & Wood LLP (available February 7, 1997),
                                  ----------------                              
     and any no-action letter obtained pursuant to clause (i) above), and (2)
     must comply with the registration and prospectus delivery requirements of
     the Securities Act in connection with a secondary resale transaction and
     that such a secondary resale transaction should 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 if the
     resales are of Exchange Notes obtained by such Holder in exchange for Notes
     acquired by such Holder directly from the Company.

          (iii) Prior to the effectiveness of the Exchange Offer Registration
     Statement, to the extent required by the Commission, the Company shall
     provide a supplemental letter to the Commission (A) stating that the
     Company is registering the Exchange Offer in reliance on the position of
     the Commission enunciated in Exxon Capital Holdings Corporation (available
                                  ----------------------------------

     letter obtained pursuant to clause (i) above and (B) including a
     representation that the Company has not entered into any arrangement or
     understanding with any Person to distribute the Exchange Notes to be
     received in the Exchange Offer and that to the best of the Company's
     information and belief, each Holder (other than an Initial Purchaser)
     participating in the Exchange Offer is acquiring the Exchange Notes in its
     ordinary course of business and has no arrangement or understanding with
     any Person to participate in the distribution of the Exchange Notes
     received in the Exchange Offer.

          (b)   Shelf Registration Statement.  In connection with the Shelf
                ----------------------------                               
Registration Statement, the Company shall comply with all the provisions of
Section 6(c) below and shall use its reasonable best efforts to effect such
registration to permit the sale of the Transfer Restricted Securities being sold
in accordance with the intended method or methods of distribution thereof, and
pursuant thereto the Company shall as expeditiously as possible prepare and file
with the Commission a Registration Statement relating to the registration on any
appropriate form under the Securities Act, which form shall be available for the
sale of the Transfer Restricted Securities in accordance with the intended
method or methods of distribution thereof.

          (c)   General Provisions. In connection with any Registration
                ------------------  
Statement and any Prospectus required by this Agreement to permit the sale or
resale of Transfer Restricted Securities (including, without limitation, any
Registration Statement and the related Prospectus required to permit resales of
Notes by Broker-Dealers), the Company shall:

          (i)   use its reasonable best efforts to (x) keep such Registration
     Statement continuously effective and (y) provide all requisite financial
     statements for the period specified in Section 3 or 4 of this Agreement, as
     applicable; upon the occurrence of any event that would cause any such
     Registration Statement or the Prospectus contained therein (A) to contain a
     material misstatement or omission or (B) not to be effective and usable for
     resale of Transfer Restricted Securities during the period required by this
     Agreement, the Company shall file promptly an appropriate amendment to such
     Registration Statement, in the case of clause (A), correcting any such
     misstatement or omission, and, in the case of either clause (A) or (B), use
     its reasonable best efforts to cause such amendment to be declared
     effective and such Registration Statement and the related Prospectus to
     become usable for their intended purpose(s) as soon as practicable
     thereafter;

          (ii)  prepare and file with the Commission such amendments and post-
     effective amendments to the Registration Statement as may be necessary to
     keep the Registration Statement effective for the applicable period set
     forth in Section 3 or 4 hereof, as applicable, or such shorter period as
     will terminate when all Transfer Restricted Securities covered by such
     Registration Statement have been sold; cause the Prospectus to be
     supplemented by any required Prospectus supplement and as so supplemented
     to be filed pursuant to Rule 424 under the Securities Act and to comply
     fully with the applicable provisions of Rules 424 and 430A under the
     Securities Act in a timely manner; and comply with the provisions of the
     Securities Act with respect to the disposition of all securities covered by
     such Registration Statement during the applicable period in accordance with
     the intended method or methods of distribution by the sellers thereof set
     forth in such Registration Statement or supplement to the Prospectus;

          (iii) in the case of a Shelf Registration Statement, advise the
     underwriter(s), if any, and selling Holders promptly and, if requested by
     any underwriter(s) or selling Holders to confirm such advice in writing,
     (A) when the Prospectus or any Prospectus supplement or post-effective
     amendment has been filed, and, with respect to any Registration Statement
     or any post-effective amendment thereto, when the same has become
     effective, (B) of any request by the Commission or any state securities
     authority for amendments to the Registration Statement or amendments or
     supplements to the Prospectus or for additional information relating
     thereto, (C) of the issuance by the Commission of any stop order suspending
     the effectiveness of the Registration Statement under the Securities Act or
     of the suspension by any state securities commission of the qualification
     of the Transfer Restricted Securities for offering or sale in any
     jurisdiction, or the initiation of any proceeding for any of the preceding
     purposes, (D) if, between the

                                      -10-
<PAGE>
 
     effective date of a Registration Statement and the closing of any sale of
     Transfer Restricted Securities covered thereby, the representations and
     warranties of the Company contained in any underwriting agreement,
     securities sales agreement or other similar agreement, if any, relating to
     the offering cease to be true and correct in all material respects or if
     the Company receives any notification with respect to the suspension of the
     qualification of the Transfer Restricted Securities for sale in any
     jurisdiction or the initiation of any proceeding for such purpose, (E) of
     the existence of any fact or the happening of any event that makes any
     statement of a material fact made in the Registration Statement, the
     Prospectus, any amendment or supplement thereto, or any document
     incorporated by reference therein untrue, or that requires the making of
     any additions to or changes in the Registration Statement or the Prospectus
     in order to make the statements therein not misleading and (F) of any
     determination by the Company that a post-effective amendment to a
     Registration Statement would be appropriate.  If at any time the Commission
     shall issue any stop order suspending the effectiveness of the Registration
     Statement, or any state securities commission or other regulatory authority
     shall issue an order suspending the qualification or exemption from
     qualification of the Transfer Restricted Securities under state securities
     or Blue Sky laws, the Company shall use its reasonable best efforts to
     obtain the withdrawal or lifting of such order at the earliest possible
     time and shall provide prompt notice to each of the selling or exchanging
     Holders of the withdrawal of any such order;

          (iv) in the case of a Shelf Registration Statement, furnish to each of
     the selling or exchanging Holders and each of the underwriter(s), if any,
     before filing with the Commission, copies of any Registration Statement or
     any Prospectus included therein or any amendments or supplements to any
     such Registration Statement or Prospectus (including all documents
     incorporated by reference after the initial filing of such Registration
     Statement), which documents will be subject to the review of such Holders
     and underwriter(s), if any, for a period of two business days, and the
     Company will not file any such Registration Statement or Prospectus or any
     amendment or supplement to any such Registration Statement or Prospectus
     (including all such documents incorporated by reference) to which selling
     Holders of a majority in aggregate principal amount of Transfer Restricted
     Securities covered by such Registration Statement or the underwriter(s), if
     any, shall reasonably object within two business days after the receipt
     thereof.  A selling Holder or underwriter, if any, shall be deemed to have
     reasonably objected to such filing if such Registration Statement,
     amendment, Prospectus or supplement, as applicable, as proposed to be
     filed, contains a material misstatement or omission;

          (v)  in the case of a Shelf Registration Statement, promptly prior to
     the filing of any document that is to be incorporated by reference into a
     Registration Statement or Prospectus, provide copies of such document to
     the selling Holders and to the underwriter(s), if any, make the Company's
     representatives available for discussion of such document and other
     customary due diligence matters, and include such information

                                      -11-
<PAGE>
 
     in such document prior to the filing thereof as such selling Holders or
     underwriter(s), if any, reasonably may request;

          (vi)   in the case of a Shelf Registration Statement, subject to
     execution of a confidentiality agreement reasonably acceptable to the
     Company, make available at reasonable times for inspection by a
     representative of the selling Holders, any underwriter participating in any
     disposition pursuant to such Registration Statement, and any attorney or
     accountant retained by such selling Holders or any of the underwriter(s),
     all financial and other records, pertinent corporate documents and

     least one conformed copy of the Registration Statement, as first filed with
     the Commission, and of each amendment thereto, including all documents
     incorporated by reference therein and all exhibits (including exhibits

                                      -12-
<PAGE>
 
          (x)  in the case of a Shelf Registration Statement, enter into such
     agreements (including an underwriting agreement), and make such
     representations and warranties, and take all such other actions in
     connection therewith in order to expedite or facilitate the disposition of
     the Transfer Restricted Securities pursuant to any Registration Statement
     contemplated by this Agreement, all to such extent as may be reasonably
     requested by any Holder of Transfer Restricted Securities or underwriter in
     connection with any sale or resale pursuant to any Registration Statement
     contemplated by this Agreement; and in connection with an Underwritten
     Registration, the Company shall:

               (A)  upon request, furnish to each selling Holder and each
          underwriter, if any, in such substance and scope as they may request
          and as are customarily made by issuers to underwriters in primary
          underwritten offerings, upon the date of the effectiveness of the
          Shelf Registration Statement:

                    (1) a certificate, dated the date of the effectiveness of
               the Shelf Registration Statement, signed by (y) the Chairman of
               the Board, its President or a Vice President and (z) the Chief
               Financial Officer of the Company, confirming, as of the date
               thereof, such customary matters as such parties may reasonably
               request;

                    (2) an opinion, dated the date of the effectiveness of the
               Shelf Registration Statement, of counsel for the Company,
               covering such customary matters as such parties may reasonably
               request, and in any event including a statement to the effect
               that such counsel has participated in conferences with officers
               and other representatives of the Company, representatives of the
               independent public accountants for the Company, the Initial
               Purchasers' representatives and the Initial Purchasers' counsel
               in connection with the preparation of such Registration Statement
               and the related Prospectus and have considered the matters
               required to be stated therein and the statements contained
               therein, although such counsel has not independently verified the
               accuracy, completeness or fairness of such statements; and that
               such counsel advises that, on the basis of the foregoing (relying
               as to materiality to a large extent upon facts provided to such
               counsel by officers and other representatives of the Company and
               without independent investigation or verification), no facts came
               to such counsel's attention that caused such counsel to believe
               that the applicable Registration Statement, at the time such
               Registration Statement or any post-effective amendment thereto
               became effective, contained an untrue statement of a material
               fact or omitted to state a material fact required to be stated
               therein or necessary to make the statements therein not
               misleading, or that the Prospectus included in such Registration
               Statement as of its date, contained an untrue statement of a
               material fact or omitted to state a material fact necessary in
               order to make the statements therein, in

                                      -13-
<PAGE>
 
               light of the circumstances under which they were made, not
               misleading. Without limiting the foregoing, such counsel may
               state further that such counsel assumes no responsibility for,
               and has not independently verified, the accuracy, completeness or
               fairness of the financial statements, notes and schedules and
               other statistical and financial data included in any Registration
               Statement contemplated by this Agreement or the related
               Prospectus; and

                    (3) a customary comfort letter, dated the date of the
               effectiveness of the Shelf Registration Statement from the
               Company's independent accountants and from the independent
               accountants of other Persons whose financial statements are
               included in the Shelf Registration Statement, in the customary
               form and covering matters of the type customarily covered in
               comfort letters by underwriters in connection with primary
               underwritten offerings.

               (B)  set forth in full or incorporate by reference in the
          underwriting agreement, if any, the indemnification provisions and
          procedures of Section 9 hereof with respect to all parties to be
          indemnified pursuant to said Section; and

               (C)  deliver such other documents and certificates as may be
          reasonably requested by such parties to evidence compliance with
          clause (A) above and with any customary conditions contained in the
          underwriting agreement or other agreement entered into by the Company
          pursuant to this clause (x), if any.

     If at any time the representations and warranties of the Company
     contemplated in clause (A)(1) above cease to be true and correct, the
     Company shall so advise the Initial Purchasers and the underwriter(s), if
     any, and each selling Holder promptly and, if requested by such Persons,
     shall confirm such advice in writing delivered to such Persons;

          (xi) in the case of a Shelf Registration Statement, prior to any
     public offering of Transfer Restricted Securities, cooperate with the
     selling Holders, the underwriter(s), if any, and their respective counsel
     in connection with the registration and qualification of the Transfer
     Restricted Securities under the securities or Blue Sky laws of such
     jurisdictions as the selling Holders or underwriter(s), if any, may
     reasonably request and do any and all other acts or things as may be
     reasonably necessary or advisable to enable the disposition in such
     jurisdictions of the Transfer Restricted Securities covered by the Shelf
     Registration Statement; provided, however, that the Company shall not be
     required to register or qualify as a foreign corporation or as a dealer in
     securities in any jurisdiction where it is not now so qualified or to take
     any action that would subject it to the service of process in suits or to
     taxation, other than as to matters and transactions relating to the
     Registration Statement in any jurisdiction where it is not now so subject;

                                      -14-
<PAGE>
 
          (xii)   in the case of an Exchange Offer Registration Statement, shall
     issue, upon the request of any Holder of Notes covered by the Exchange
     Offer Registration Statement, Exchange Notes in the same amount as the
     Notes surrendered to the Company by such Holder in exchange therefor or
     being sold by such Holder; such Exchange Notes to be registered in the name
     of such Holder or in the name of the purchaser(s) of such Exchange Notes,
     as the case may be; in return, the Notes held by such Holder shall be
     surrendered to the Company for cancellation;

          (xiii)  in the case of a Shelf Registration Statement, cooperate with
     the selling Holders and the underwriter(s), if any, to facilitate the
     timely preparation and delivery of certificates representing Transfer
     Restricted Securities to be sold and not bearing any restrictive legends;
     and enable such Transfer Restricted Securities to be in such denominations
     (consistent with the provisions of the Indenture) and registered in such
     names as the selling Holders or the underwriter(s), if any, may reasonably
     request at least two business days prior to any sale of Transfer Restricted
     Securities made by such underwriter(s);

          (xiv)   use its reasonable best efforts to cause the Transfer
     Restricted Securities covered by the Registration Statement to be
     registered with or approved by such other governmental agencies or
     authorities as may be necessary to enable the seller or sellers thereof or
     the underwriter(s), if any, to consummate the disposition of such Transfer
     Restricted Securities, subject to the proviso contained in clause (xi)
     above;

          (xv)    if any fact or event contemplated by clause (c)(iii)(E) above
     shall exist or have occurred, prepare and file with the Commission a
     supplement or post-effective amendment to the Registration Statement or
     related Prospectus or any document incorporated therein by reference or
     file any other required document so that, as thereafter delivered to the
     purchasers of Transfer Restricted Securities, such Prospectus will not
     contain an untrue statement of a material fact or omit to state any
     material fact necessary to make the statements therein, in light of the
     circumstances under which they were made, not misleading;

          (xvi)   provide CUSIP numbers for all Transfer Restricted Securities
     not later than the effective date of the Registration Statement and provide
     certificates for the Transfer Restricted Securities;

          (xvii)  cooperate and assist in any filings required to be made with
     the NASD and in the performance of any due diligence investigation by any
     underwriter (including any "qualified independent underwriter") that is
     required to be retained in accordance with the rules and regulations of the
     NASD, and use its reasonable best efforts to cause such Registration
     Statement to become effective and approved by such governmental agencies or
     authorities as may be necessary to enable the Holders selling Transfer
     Restricted Securities to consummate the disposition of such Transfer
     Restricted Securities; provided,

                                      -15-
<PAGE>
 
     however, that the Company shall not be required to register or qualify as a
     foreign corporation or as a dealer in securities in any jurisdiction where
     it is not now so qualified or to take any action that would subject it to
     the service of process in suits or to taxation, other than as to matters
     and transactions relating to the Registration Statement in any jurisdiction
     where it is not now so subject;

          (xviii)  otherwise use its reasonable best efforts to comply with all
     applicable rules and regulations of the Commission, and make generally
     available to the Holders, as soon as practicable, a consolidated earnings
     statement meeting the requirements of Rule 158 (which need not be audited)
     for the twelve-month period (A) commencing at the end of any fiscal quarter
     in which Transfer Restricted Securities are sold to underwriters in a firm
     or reasonable best efforts Underwritten Offering or (B) if not sold to
     underwriters in such an offering, beginning with the first month of the
     Company's first fiscal quarter commencing after the effective date of the
     Registration Statement;

          (xix)    cause the Indenture to be qualified under the TIA not later
     than the effective date of the first Registration Statement required by
     this Agreement, and, in connection therewith, cooperate with the Trustee
     and the Holders of Notes to effect such changes to the Indenture as may be
     required for such Indenture to be so qualified in accordance with the terms
     of the TIA; and execute and use its reasonable best efforts to cause the
     Trustee to execute all documents that may be required to effect such
     changes and all other forms and documents required to be filed with the
     Commission to enable such Indenture to be so qualified in a timely manner;
     and

          (xx)     provide promptly to each Holder upon reasonable request each
     document filed with the Commission pursuant to the requirements of Section
     13 and Section 15 of the Exchange Act.

          Each Holder agrees by acquisition of a Transfer Restricted Security
that, upon receipt of any notice from the Company of the existence of any fact
of the kind described in Section 6(c)(iii)(E) hereof, such Holder will forthwith
discontinue disposition of Transfer Restricted Securities pursuant to the
applicable Registration Statement until such Holder's receipt of the copies of
the supplemented or amended Prospectus contemplated by Section 6(c)(xv) hereof,
or until such Holder is advised in writing (the "Advice") by the Company that
the use of the Prospectus may be resumed, and has received copies of any
additional or supplemental filings that are incorporated by reference in the
Prospectus.  If so directed by the Company, each Holder will deliver to the
Company (at the Company's expense) all copies, other than permanent file copies
then in such Holder's possession, of the Prospectus covering such Transfer
Restricted Securities that was current at the time of receipt of such notice.
In the event that the Company shall give any such notice, the time period
regarding the effectiveness of such Registration Statement set forth in Section
3 or 4 hereof, as applicable, shall be extended by the number of days during the
period from and including the date of the giving of such notice pursuant to
Section 6(c)(iii)(E) hereof to and including the date when each selling Holder

                                      -16-
<PAGE>
 
covered by such Registration Statement shall have received the copies of the
supplemented or amended Prospectus contemplated by Section 6(c)(xv) hereof or
shall have received the Advice.

          7.    Participation of Broker-Dealers in Exchange Offer.

          (a)   Participating Broker-Dealer May Be Deemed an "Underwriter".  The
                ----------------------------------------------------------      
Commission has taken the position that any Broker-Dealer that receives Exchange
Notes for its own account in the Exchange Offer in exchange for Notes that were
acquired by such Broker-Dealer as a result of market-making or other trading
activities (a "Participating Broker-Dealer") may be deemed to be an
"underwriter" within the meaning of the Securities Act and must deliver a
prospectus meeting the requirements of the Securities Act in connection with any
resale of such Exchange Notes.

          The Company understands that it is the Commission's position that if
the Prospectus contained in the Exchange Offer Registration Statement includes a
"Plan of Distribution" containing a statement to the above effect and the means
by which Participating Broker-Dealers may resell the Exchange Notes, without
naming the Participating Broker-Dealers or specifying the amount of Exchange
Notes owned by them, such Prospectus may be delivered by Participating Broker-
Dealers to satisfy their prospectus delivery obligation under the Securities Act
in connection with resales of Exchange Notes for their own accounts, so long as
the Prospectus otherwise meets the requirements of the Securities Act.

          (b)   Provisions Regarding Shelf Registration Statement to Apply to
                -------------------------------------------------------------
Exchange Offer Registration.  In light of the above, notwithstanding the other
- ---------------------------                                                   
provisions of this Agreement, the Company agrees that the provisions of this
Agreement as they relate to a Shelf Registration Statement shall also apply to
an Exchange Offer Registration to the extent, and with such reasonable
modifications thereto, as may be reasonably requested by the Initial Purchasers
or by one or more Participating Broker-Dealers, in each case as provided in
clause (ii) below, in order to expedite or facilitate the disposition of any
Exchange Notes by Participating Broker-Dealers consistent with the positions of
the Commission recited in Section 7(a) above; provided, however, that:

          (i)   the Company shall not be required to amend or supplement the
     Prospectus contained in the Exchange Offer Registration Statement, as would
     otherwise be contemplated by Section 6(c)(xv), for a period exceeding 180
     days after the last date of acceptance for exchange (as such period may be
     extended pursuant to the last paragraph of Section 6 of this Agreement) and
     Participating Broker-Dealers shall not be authorized by the Company to
     deliver and shall not deliver such Prospectus after such period in
     connection with the resales contemplated by this Section 7; and

          (ii)  the application of the Shelf Registration Statement procedures
     set forth in Section 4 of this Agreement to an Exchange Offer Registration,
     to the extent not required by the positions of the Commission or the
     Securities Act and the rules and regulations

                                      -17-
<PAGE>
 
     thereunder, will be in conformity with the reasonable request to the
     Company by the Initial Purchasers or with the reasonable request in writing
     to the Company by one or more broker-dealers who certify to the Initial
     Purchasers and the Company in writing that they anticipate that they will
     be Participating Broker-Dealers;

provided further that, in connection with such application of the Shelf
Registration Statement procedures set forth in Section 4 to an Exchange Offer
Registration, the Company shall be obligated (x) to deal only with one entity
representing the Participating Broker-Dealers, which shall be the Representative
unless it elects not to act as such representative, (y) to pay the fees and
expenses of only one counsel representing the Participating Broker-Dealers,
which shall be counsel selected by the Representative and reasonably acceptable
to the Company (unless such counsel elects not to so act), and (z) to cause to
be delivered only one, if any, "cold comfort" letter with respect to the
Prospectus in the form existing on the last date of acceptance for exchange and
with respect to each subsequent amendment or supplement, if any, effected during
the period specified in clause (i) above.

          (c)   Liability of the Initial Purchasers.  The Initial Purchasers 
                ----------------------------------- 
shall have no liability to the Company or any Holder with respect to any request
that they may make pursuant to Section 7(b) above.

          8.    Registration Expenses.

          (a)   All expenses incident to the Company's performance of or
compliance with this Agreement will be borne by the Company, regardless of
whether a Registration Statement becomes effective, including without
limitation: (i) all registration and filing fees and expenses (including filings
made by any Initial Purchaser or Holder with the NASD (and, if applicable, the
reasonable fees and expenses of any "qualified independent underwriter") and its
counsel that may be required by the rules and regulations of the NASD); (ii) all
fees and expenses of compliance with federal securities and state Blue Sky or
securities laws; (iii) all expenses of printing (including printing certificates
for the Exchange Notes to be issued in the Exchange Offer and printing of
Prospectuses), and associated messenger and delivery services and
telecommunications usage; (iv) all fees and disbursements of counsel for the
Company and, subject to Section 8(b) below, the Holders of Transfer Restricted
Securities; (v) all application and filing fees in connection with listing Notes
on a national securities exchange or automated quotation system; and (vi) all
fees and disbursements of independent certified public accountants of the
Company and other Persons whose financial statements are included in a
Registration Statement (including the expenses of any special audit and comfort
letters required by or incident to such performance).

          The Company will, in any event, bear its internal expenses (including,
without limitation, all salaries and expenses of its officers and employees
performing legal or accounting duties), the expenses of any annual audit and the
fees and expenses of any Person, including special experts, retained by the
Company.

                                      -18-
<PAGE>
 
          (b)   In connection with any Registration Statement required by this
Agreement (including, without limitation, the Exchange Offer Registration
Statement and the Shelf Registration Statement), the Company will reimburse the
Initial Purchasers and the Holders of Transfer Restricted Securities being
tendered in the Exchange Offer and/or resold pursuant to the "Plan of
Distribution" contained in the Exchange Offer Registration Statement or
registered pursuant to the Shelf Registration Statement, as applicable, for the
reasonable fees and disbursements of not more than one counsel, who shall be
counsel selected by the Representative and reasonably acceptable to the Company
(unless such counsel elects not to so act).  The Company shall not be required
to pay any underwriting discount, commission or similar fee related to the sale
of any securities.

          9.    Indemnification and Contribution.

          (a)   The Company to Indemnify Holders.  In connection with a Shelf
                --------------------------------                             
Registration Statement or in connection with any delivery of a Prospectus
contained in an Exchange Offer Registration Statement by any Participating
Broker-Dealer or Initial Purchaser, as applicable, who seeks to sell Exchange
Notes, the Company and Primus Telecommunications, Inc. a Delaware corporation,
and Primus Telecommunications (Australia) Pty. Ltd., a company organized under
the laws of Australia (together, the "Principal Subsidiaries"), jointly and
severally, shall indemnify and hold harmless each Holder of Transfer Restricted
Securities included within any such Shelf Registration Statement and each
Participating Broker-Dealer or Initial Purchaser selling Exchange Notes (each, a
"Participant"), such Participant's officers and directors and each person, if
any, who controls any Participant within the meaning of Section 15 of the
Securities Act from and against any loss, claim, damage or liability, joint or
several, or any action in respect thereof (including, but not limited to, any
loss, claim, damage, liability or action relating to purchases and sales of
Notes), to which such Participant, officer, director or controlling person may
become subject, under the Securities Act or otherwise, insofar as such loss,
claim, damage, liability or action arises out of, or is based upon, (i) any
untrue statement or alleged untrue statement of a material fact contained in (A)
any preliminary Prospectus, Registration Statement or Prospectus or in any
amendment or supplement thereto or (B) any blue sky application or other
document prepared or executed by the Company (or based upon any written
information furnished by the Company) specifically for the purpose of qualifying
any or all of the Exchange Notes under the securities laws of any state or other
jurisdiction (any such application, document or information being hereinafter
called a "Blue Sky Application"), (ii) the omission or alleged omission to state
in any (x) preliminary Prospectus or Prospectus or in any amendment or
supplement thereto, any material fact required to be stated therein or necessary
to make the statements therein not misleading, in light of the circumstances in
which they were made, and (y) Registration Statement or in any amendment or
supplement thereto, or in any Blue Sky Application any material fact required to
be stated therein or necessary to make the statements therein not misleading or
(iii) any act or failure to act, or any alleged act or failure to act, by any
Participant in connection with, or relating in any manner to, the Notes or the
offering contemplated hereby, and which is included as part of or referred to in
any loss, claim, damage, liability or action arising out of or based upon
matters covered in (i) or (ii) above (provided that

                                      -19-
<PAGE>
 
the Company and the Principal Subsidiaries shall not be liable in the case of
any matter covered by this clause (iii) to the extent that it is determined in a
final judgment by a court of competent jurisdiction that such loss, claim,
damage, liability or action resulted directly from any such act or failure to
act undertaken or omitted to be taken by such Participant through its gross
negligence or wilful misconduct), and shall reimburse each Participant and each
such officer, director or controlling person promptly upon demand for any legal
or other expenses reasonably incurred by that Participant, officer, director or
controlling person  in connection with investigating or defending or preparing
to defend against any such loss, claim, damage, liability or action as such
expenses are incurred; provided, however, that the Company and the Principal
Subsidiaries shall not be liable in any such case to the extent that any such
loss, claim, damage, liability or action arises out of, or is based upon, any
untrue statement or alleged untrue statement or omission or alleged omission
made in any preliminary Prospectus, Prospectus or Registration Statement, in any
amendment or supplement thereto, or in any Blue Sky Application in reliance upon
and in conformity with written information concerning such Participant furnished
to the Company by or on behalf of any Participant specifically for inclusion
therein; provided further that as to any preliminary Prospectus, this indemnity
agreement shall not inure to the benefit of any Participant or any officer,
director or controlling person of that Participant on account of any loss,
claim, damage, liability or action arising from the sale of the Exchange Notes
or any Notes sold pursuant to a Shelf Registration Statement to any person by
such Participant if (i) that Participant failed to send or give a copy of the
Prospectus, as the same may be amended or supplemented, to that person within
the time required by the Securities Act and (ii) the untrue statement or alleged
untrue statement of a material fact or omission or alleged omission to state a
material fact in such preliminary Prospectus was corrected in the Prospectus or
a supplement or amendment thereto, as the case may be, unless in each case, such
failure resulted from noncompliance by the Company with Section 6(c).  The
foregoing indemnity agreement is in addition to any liability which the Company
and the Principal Subsidiaries may otherwise have to any Participant or to any
officer, director or controlling person of that Participant.  In connection with
any Underwritten Offering permitted by Section 6(c) hereof, the Company and the
Principal Subsidiaries will also indemnify the underwriters, if any, selling
brokers, dealers and similar securities industry professionals participating in
the distribution, their officers and directors and each Person who controls such
Persons (within the meaning of the Securities Act and the Exchange Act) to the
same extent as provided above with respect to the indemnification of the
Holders, if requested in connection with any Registration Statement.

          (b)   Participants to Indemnify the Company and its Directors,
                --------------------------------------------------------
 Officers and Controlling Persons.  Each Participant, severally and not jointly,
- ---------------------------------                                 
shall indemnify and hold harmless the Company, its directors and officers, and
each person, if any, who controls the Company within the meaning of Section 15
of the Securities Act, from and against any loss, claim, damage or liability,
joint or several, or any action in respect thereof, to which the Company or any
such director, officer or controlling person may become subject, under the
Securities Act or otherwise, insofar as such loss, claim, damage, liability or
action arises out of, or is based upon, (i) any untrue statement or alleged
untrue statement of a material fact contained in (A) any preliminary Prospectus,
Registration Statement or Prospectus or in any amendment or

                                      -20-
<PAGE>
 
supplement thereto or (B) any Blue Sky Application or (ii) the omission or
alleged omission to state in any (x) preliminary Prospectus or Prospectus or in
any amendment or supplement thereto, any material fact required to be stated
therein or necessary to make the statements therein in light of the
circumstances in which they were made not misleading, and (y) Registration
Statement or in any amendment or supplement thereto, or in any Blue Sky
Application any material fact required to be stated therein or necessary to make
the statements therein not misleading but in the case of clauses (i) and (ii)
only to the extent that the untrue statement or alleged untrue statement or
omission or alleged omission was made in reliance upon and in conformity with
the written information concerning such Participant furnished to the Company or
the Trustee by or on behalf of that Participant specifically for inclusion
therein, and shall reimburse the Company and any such director, officer or
controlling person for any legal or other expenses reasonably incurred by the
Company and the Principal Subsidiaries or any such director, officer or
controlling person in connection with investigating or defending or preparing to
defend against any such loss, claim, damage, liability or action as such
expenses are incurred.  The foregoing indemnity agreement is in addition to any
liability which any Participant may otherwise have to the Company or any such
director, officer or controlling person.

          (c)   Notification of Indemnifying Party; Counsel; Settlement. 
                -------------------------------------------------------       
 Promptly after receipt by an indemnified party under this Section 9 of notice
of any claim or the commencement of any action, the indemnified party shall, if
a claim in respect thereof is to be made against the indemnifying party under
this Section 9, notify the indemnifying party in writing of the claim or the
commencement of that action; provided, however, that the failure to notify the
indemnifying party shall not relieve it from any liability which it may have
under this Section 9 except to the extent the indemnifying party has been
materially prejudiced by such failure and provided further that the failure to
notify the indemnifying party shall not affect any liability which it may have
to an indemnified party otherwise than under this Section 9. If any such claim
or action shall be brought against an indemnified party, and it shall notify the
indemnifying party thereof, the indemnifying party shall be entitled to
participate therein and, to the extent that it wishes, jointly with any other
similarly notified indemnifying party, to assume the defense thereof with
counsel reasonably satisfactory to the indemnified party. After notice from the
indemnifying party to the indemnified party of its election to assume the
defense of such claim or action, the indemnifying party shall not be liable to
the indemnified party under this Section 9 for any legal or other expenses
subsequently incurred by the indemnified party in connection with the defense
thereof other than reasonable costs of investigation; provided, however, that
the indemnified party shall have the right to employ counsel to represent
jointly the indemnified party and its respective directors, officers and
controlling persons who may be subject to liability arising out of any claim in
respect of which indemnity may be sought by the indemnified party against the
indemnifying party under this Section 9 if such indemnified party shall have
been advised in writing that the representation of such indemnified party and
those directors, officers and controlling persons by the same counsel would be
inappropriate under applicable standards of professional conduct due to actual
or potential differing interests between them, and in that event the fees and
expenses of such separate counsel shall be paid by the indemnifying party. It is
understood that the indemnifying party shall not be liable for the fees and
expenses of more than one separate firm

                                      -21-
<PAGE>
 
(in addition to local counsel in each jurisdiction) for all indemnified parties
in connection with any proceeding or related proceedings.  Each indemnified
party, as a condition of the indemnity agreements contained in Sections 9(a) and
9(b), shall use its reasonable best efforts to cooperate with the indemnifying
party in the defense of any such action or claim.  No indemnifying party shall
(i) without the prior written consent of the indemnified parties (which consent
shall not be unreasonably withheld), settle or compromise or consent to the
entry of any judgment with respect to any pending or threatened claim, action,
suit or proceeding in respect of which indemnification or contribution may be
sought hereunder (whether or not the indemnified parties are actual or potential
parties to such claim or action) unless such settlement, compromise or consent
includes an unconditional release of each indemnified party from all liability
arising out of such claim, action, suit or proceeding, or (ii) be liable for any
settlement of any such action effected without its written consent (which
consent shall not be unreasonably withheld), but if settled with its written
consent or if there be a final judgment of the plaintiff in any such action, the
indemnifying party agrees to indemnify and hold harmless any indemnified party
from and against any loss or liability by reason of such settlement or judgment
in accordance with this Section 9.

          (d)   Indemnification Unavailable.  If the indemnification provided 
                ---------------------------
for in this Section 9 shall for any reason be unavailable to or insufficient to
hold harmless an indemnified party under Section 9(a) or 9(b) in respect of any
loss, claim, damage or liability, or any action in respect thereof, referred to
therein, then each indemnifying party shall, in lieu of indemnifying such
indemnified party, contribute to the amount paid or payable by such indemnified
party as a result of such loss, claim, damage or liability, or action in respect
thereof, (i) in such proportion as shall be appropriate to reflect the relative
benefits received by the Company and the Principal Subsidiaries, on the one
hand, and the Participants, on the other hand, from the offering of the Exchange
Notes or (ii) if the allocation provided by clause (i) above is not permitted by
applicable law, in such proportion as is appropriate to reflect not only the
relative benefits referred to in clause (i) above but also the relative fault of
the Company and the Principal Subsidiaries, on the one hand, and the
Participants, on the other hand, with respect to the statements or omissions
which resulted in such loss, claim, damage or liability, or action in respect
thereof, as well as any other relevant equitable considerations. The relative
benefits received by the Company and the Principal Subsidiaries, on the one
hand, and the Participants, on the other hand, with respect to such offering
shall be deemed to be in the same proportion as the total net proceeds from the
offering of the Exchange Notes purchased under this Agreement (before deducting
expenses) received by the Company and the Principal Subsidiaries, on the one
hand, and the total underwriting commissions and discounts received by the
Participants with respect to the Notes purchased under the Purchase Agreement,
on the other hand, bear to the total gross proceeds from the offering of the
Exchange Notes under this Agreement, in each case as set forth in the table on
the cover page of the Memorandum. The relative fault shall be determined by
reference to, among other things, whether the untrue or alleged untrue statement
of a material fact or omission or alleged omission to state a material fact
relates to information supplied by the Company and the Principal Subsidiaries,
on the one hand, or the Participants, on the other hand, the intent of the
parties and their relative knowledge, access to information and opportunity to

                                      -22-
<PAGE>
 
correct or prevent such statement or omission.  Each of the Company and the
Principal Subsidiaries and the Participants agrees that it would not be just and
equitable if contributions pursuant to this Section 9(d) were to be determined
by pro rata allocation (even if either the Participants or the Company and the
Principal Subsidiaries, as the case may be, were treated as one entity for such
purpose) or by any other method of allocation which does not take into account
the equitable considerations referred to herein.  The amount paid or payable by
an indemnified party as a result of the loss, claim, damage or liability, or
action in respect thereof, referred to above in this Section 9(d) shall be
deemed to include, subject to the limitations set forth above, any legal or
other expenses reasonably incurred by such indemnified party in connection with
investigating or defending any such action or claim.  Notwithstanding the
provisions of this Section 9(d), no Participant shall be required to indemnify
or contribute any amount in excess of the amount by which proceeds received by
the Participants from an offering of the Exchange Notes exceeds the amount of
any damages which such Participant has otherwise paid or become liable to pay by
reason of any untrue or alleged untrue statement or omission or alleged
omission.  No person guilty of fraudulent misrepresentation (within the meaning
of Section 11(f) of the Securities Act) shall be entitled to contribution from
any person who was not guilty of such fraudulent misrepresentation.  The
remedies provided for in this Section 9 are not exclusive and shall not limit
any rights or remedies which may otherwise be available to any indemnified party
at law or in equity.  The Participants' obligations to contribute as provided in
this Section 9(d) are several in proportion to their respective underwriting
obligations and not joint.
 
          (e)   The indemnity and contribution provisions contained in this
Section 9 shall remain operative and in full force and effect regardless of (i)
any termination of this Agreement, (ii) any investigation made by or on behalf
of any Initial Purchaser, any Holder or any person controlling any Initial
Purchaser or any Holder, or by or on behalf of the Company, its officers or
directors or any person controlling the Company, (iii) acceptance of any of the
Exchange Notes and (iv) any sale of Transfer Restricted Securities pursuant to a
Shelf Registration Statement.

          10.   Rule 144A.

          The Company hereby agrees with each Holder, for so long as any
Transfer Restricted Securities remain outstanding, to make available to any
Holder or beneficial owner of Transfer Restricted Securities in connection with
any sale thereof and any prospective purchaser of such Transfer Restricted
Securities from such Holder or beneficial owner, the information required by
Rule 144A(d)(4) under the Securities Act in order to permit resales of such
Transfer Restricted Securities pursuant to Rule 144A.

                                      -23-
<PAGE>
 
          11.   Participation in Underwritten Registrations.

          No Holder may participate in any Underwritten Registration hereunder
unless such Holder (a) agrees to sell such Holder's Transfer Restricted
Securities on the basis provided in any underwriting arrangements approved by
the Persons entitled hereunder to approve such arrangements and (b) completes
and executes all questionnaires, powers of attorney, indemnities, underwriting
agreements, lockup letters and other documents reasonably required under the
terms of such underwriting arrangements.

          12.   Selection of Underwriters.

          The Holders of Transfer Restricted Securities covered by the Shelf
Registration Statement who desire to do so may sell such Transfer Restricted
Securities in an Underwritten Offering.  In any such Underwritten Offering, the
investment banker or investment bankers and manager or managers that will
administer the offering will be selected by the Holders of a majority in
aggregate principal amount of the Transfer Restricted Securities included in
such offering; provided that such investment bankers and managers must be
reasonably satisfactory to the Company.

          13.   Miscellaneous.

          (a)   Remedies.  The Company agrees that monetary damages (including
                --------                                                      
Liquidated Damages) would not be adequate compensation for any loss incurred by
reason of a breach by it of the provisions of this Agreement and hereby agrees
to waive the defense in any action for specific performance that a remedy at law
would be adequate.

          (b)   No Inconsistent Agreements.  The Company will not on or after 
                --------------------------                              
the date of this Agreement enter into any agreement with respect to its
securities that is inconsistent with the rights granted to the Holders in this
Agreement or otherwise conflicts with the provisions hereof. The rights granted
to the Holders hereunder do not in any way conflict with and are not
inconsistent with the rights granted to the holders of the Company's securities
under the provisions of any agreement in effect on the date hereof.

          (c)   Adjustments Affecting the Notes.  The Company will not take
                -------------------------------                                
any action, or permit any change to occur, with respect to Notes that would
materially and adversely affect the ability of the Holders to Consummate any
Exchange Offer unless such action or change is required by applicable law.

          (d)   Amendments and Waivers.  The provisions of this Agreement,
                ----------------------                                    
including the provisions of this sentence, may not be amended, modified or
supplemented, and waivers or consents to or departures from the provisions
hereof may not be given unless the Company has obtained the written consent of
Holders of at least a majority of the outstanding principal amount of Transfer
Restricted Securities; provided, however, that no amendment, modification,

                                      -24-
<PAGE>
 
supplement, waiver or consent to or departure from the provisions of Section 8
hereof shall be effective as against any Holder of Transfer Restricted
Securities unless consented to in writing by such Holder.  Notwithstanding the
foregoing, a waiver or consent to departure from the provisions hereof that
relates exclusively to the rights of Holders whose securities are being tendered
pursuant to the Exchange Offer and that does not affect directly or indirectly
the rights of other Holders whose securities are not being tendered pursuant to
such Exchange Offer may be given by the Holders of a majority of the outstanding
principal amount of Transfer Restricted Securities being tendered or registered.

not inure to the benefit of or be binding upon a successor, transferee or assign
of a Holder unless and to the extent such successor, transferee or assign

any Holder shall acquire Transfer Restricted Securities, in any manner, whether
by operation of law or otherwise, such Transfer Restricted Securities shall be
held subject to all of the terms of this Agreement, and by taking and holding
such Transfer Restricted Securities such Person shall be conclusively deemed to

                ------------                                                  
counterparts and by the parties hereto in separate counterparts, each of which

together shall constitute one and the same agreement.

          (j)   Headings.  The headings in this Agreement are for convenience of
                --------                                                        
reference only and shall not limit or otherwise affect the meaning hereof.

          (k)   GOVERNING LAW.  THIS AGREEMENT  SHALL  BE  GOVERNED BY  AND
                -------------                                               
CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

          (l)   Consent to Jurisdiction.  Each party irrevocably agrees that any
                -----------------------                                         
legal suit, action or proceeding arising out of or based upon this Agreement or
the transactions contemplated hereby ("Related Proceedings") may be instituted
in the federal courts of the United States of America located in the City of New
York or the courts of the State of New York in each case located in the Borough
of Manhattan in the City of New York (collectively, the "Specified Courts"), and
irrevocably submits to the exclusive jurisdiction (except for proceedings
instituted in regard to the enforcement of a judgment of any such court (a
"Related Judgment"), as to which such jurisdiction is non-exclusive) of such
courts in any such suit, action or proceeding.  The parties further agree that
service of any process, summons, notice or document by mail to such party's
address set forth above shall be effective service of process for any lawsuit,
action or other proceeding brought in any such court.  The parties hereby
irrevocably and unconditionally waive any objection to the laying of venue of
any lawsuit, action or other proceeding in the Specified Courts, and hereby
further irrevocably and unconditionally waive and agree not to plead or claim in
any such court that any such lawsuit, action or other proceeding brought in any
such court has been brought in an inconvenient forum.  Primus Telecommunications
(Australia) Pty. Ltd. hereby irrevocably appoints CT Corporation System, which
currently maintains a New York City office at 1633 Broadway, New York, New York
10019, United States of America, as its agent to receive service of process or
other legal summons for purposes of any such action or proceeding that may be
instituted in any state or federal court in the City and State of New York.

          (m)   Waiver of Immunity.  With respect to any Related Proceeding,
                ------------------                                          
each party irrevocably waives, to the fullest extent permitted by applicable
law, all immunity (whether on the basis of sovereignty or otherwise) from
jurisdiction, service of process, attachment (both before and after judgment)
and execution to which it might otherwise be entitled in the Specified

                                      -27-
<PAGE>
 
Courts, and with respect to any Related Judgment, each party waives any such
immunity in the Specified Courts or any other court of competent jurisdiction,
and will not raise or claim or cause to be pleaded any such immunity at or in
respect of any such Related Proceeding or Related Judgment, including, without
limitation, any immunity pursuant to the United States Foreign Sovereign
Immunities Act of 1976, as amended.

          (n)   Severability.  In the event that any one or more of the 
                ------------                                            
provisions contained herein, or the application thereof in any circumstance, is
held invalid, illegal or unenforceable, the validity, legality and
enforceability of any such provision in every other respect and of the remaining
provisions contained herein shall not be affected or impaired thereby.

          (o)   Entire Agreement.  This Agreement, together with each of the
                ----------------                                            
Related Transaction Documents, is intended by the parties as a final expression
of their agreement and intended to be a complete and exclusive statement of the
agreement and understanding of the parties hereto in respect of the subject
matter contained herein.  There are no restrictions, promises, warranties or
undertakings, other than those set forth or referred to herein with respect to
the registration rights granted by the Company with respect to the Transfer
Restricted Securities.  This Agreement supersedes all prior agreements and
understandings between the parties with respect to such subject matter.

          (p)   Required Consents.  Whenever the consent or approval of Holders 
                -----------------   
of a specified percentage of Transfer Restricted Securities is required
hereunder, Transfer Restricted Securities held by the Company or its affiliates
(as such term is defined in Rule 405 under the Securities Act) shall not be
counted in determining whether such consent or approval was given by the Holders
of such required percentage.

          14.   Additional Representations of Primus Telecommunications,
Incorporated and Primus Telecommunications Pty. Ltd.

          The Registration Rights Agreement has been duly authorized by Primus
Telecommunications, Incorporated and Primus Telecommunications Pty. Ltd. (the
"Principal Subsidiaries"), and when duly executed by the proper officers of the
Principal Subsidiaries (assuming due execution and delivery by the Initial
Purchasers) and delivered by the Company, will constitute a valid and legally
binding agreement of the Company enforceable against the Company in accordance
with its terms, except (i) where the enforceability thereof may be limited by
bankruptcy, insolvency, reorganization, fraudulent conveyance, moratorium or
other similar laws now or hereafter in effect relating to rights of creditors
and other obligees generally, (ii) where the remedy of specific performance and
other forms of equitable relief may be subject to certain equitable defenses and

  The undersigned acknowledges receipt of the Prospectus, dated      , 1998
("Exchange Offer"), of Primus Telecommunications Group, Inc., a Delaware
corporation (the "Company"), relating to the offer of the Company, upon the
terms and subject to the conditions set forth in the Exchange Offer and in
this Letter of Transmittal and the instructions hereto (which together with
the Exchange Offer and the instructions hereto constitute the "Offer"), to
exchange a new series of its 9 7/8% Senior Notes due 2008 (the "Exchange
Notes") which have been registered under the Securities Act of 1933 (the
"Securities Act") for any and all of its outstanding 9 7/8% Senior Notes due
2008 ("Initial Notes"), at the rate of $1,000 principal amount of the Exchange
Notes for each $1,000 principal amount of the Initial Notes. Capitalized terms
used but not defined herein have the meanings given to them in the Exchange
Offer.
 
  The undersigned has completed the appropriate boxes below and signed this
Letter of Transmittal to indicate the action the undersigned desires to take
with respect to the Offer.
 
  This Letter of Transmittal is to be used whether the Initial Notes are to be
physically delivered herewith, or whether guaranteed delivery procedures or
book-entry delivery procedures are being used, pursuant to the procedures set
forth under "The Exchange Offer" in the Exchange Offer. If delivery of Initial
Notes is to be made by book-entry transfer to the account maintained by the
Exchange Agent at The Depository Trust Company ("DTC"), this Letter of
Transmittal need not be manually executed, provided, however, that tenders of
Initial Notes must be effected in accordance with the procedures mandated by
DTC and the procedures set forth in the Exchange Offer under the caption "The
Exchange Offer--Procedures for Tendering Initial Notes--Book-Entry Delivery."
If a person or entity in whose name Initial Notes are registered on the books
of the Registrar (a "Registered Holder") desires to tender Initial Notes and
such Initial Notes are not immediately available or time will not permit all
documents required by the Offer to reach the Exchange Agent (or such
Registered Holder is unable to complete the procedure for book-entry transfer
on a timely basis) prior to 5:00 P.M. New York City time on      , 1998 (the
"Expiration Date"), a tender may be effected in accordance with the guaranteed
delivery procedures set forth in the Exchange Offer under the caption "The
Exchange Offer--Procedures for Tendering Initial Notes--Guaranteed Delivery
Procedures." See Instruction 1.
 
           DELIVERY OF DOCUMENTS TO THE BOOK-ENTRY TRANSFER FACILITY
              DOES NOT CONSTITUTE DELIVERY TO THE EXCHANGE AGENT
 
              PLEASE READ THE ACCOMPANYING INSTRUCTIONS CAREFULLY

Ladies and Gentlemen:
 
  Upon the terms and subject to the conditions of the Offer, the undersigned
hereby tenders to the Company the principal amount of the Initial Notes
indicated below. Subject to, and effective upon, the acceptance for exchange
of the Initial Notes tendered hereby, the undersigned hereby irrevocably
sells, assigns and transfers to or upon the order of the Company all right,
title and interest in and to such Initial Notes and hereby irrevocably
constitutes and appoints the Exchange Agent the true and lawful agent and
attorney-in-fact of the undersigned (with full knowledge that said exchange
agent also acts as the agent of the Company) with respect to such Initial
Notes, with full power of substitution (such power of attorney being deemed to
be an irrevocable power coupled with an interest), to take such further action
as may be required in connection with the delivery, tender and exchange of the
Initial Notes.
 
  The undersigned acknowledges that this Offer is being made in reliance on an
interpretation by the staff of the Securities and Exchange Commission (the
"SEC") that the Exchange Notes issued pursuant to the Exchange Offer in
exchange for the Initial Notes may be offered for resale, resold and otherwise
transferred by holders thereof (other than (i) a broker-dealer who purchased
Initial Notes directly from the Company for resale pursuant to Rule 144A under
the Securities Act, or (ii) a person that is an "affiliate" of the Company
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 such Exchange 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 Exchange Notes. See Morgan Stanley &
Co. Inc., SEC No-Action Letter (available June 5, 1991); The Exchange Offer
under the caption "The Exchange Offer--Resales of the Exchange Notes."
 
  The undersigned acknowledges that the Exchange Notes have not been
registered or qualified under any state securities laws. This Offer is being
made to: (i) U.S. persons pursuant to exemptions from such laws for sales to
institutional investors, and (ii) non-U.S. persons (within the meaning of
Regulation S under the Securities Act), as state securities laws do not apply
to sales to persons who are not residents of any state. The undersigned hereby
represents and warrants that the undersigned is either (i) a "qualified
institutional buyer" within the meaning of Rule 144A under the Securities Act,
(ii) an institutional "accredited investor" within the meaning of subparagraph
(a)(1), (2), (3) or (7) of Rule 501 under the Securities Act or (iii) a non-
U.S. person (within the meaning of Regulation S under the Securities Act).
 
  THE UNDERSIGNED UNDERSTANDS AND AGREES THAT THE COMPANY RESERVES THE RIGHT
NOT TO ACCEPT TENDERED INITIAL NOTES FROM ANY TENDERING HOLDER IF THE COMPANY
DETERMINES, IN ITS SOLE AND ABSOLUTE DISCRETION, THAT SUCH ACCEPTANCE COULD
RESULT IN A VIOLATION OF APPLICABLE SECURITIES LAWS.
 
  The undersigned, if the undersigned is a beneficial holder, represents, or,
if the undersigned is a broker, dealer, commercial bank, trust company or
other nominee, represents that it has received representations from the
beneficial owners of the Initial Notes stating, (as defined in the Exchange
Offer) that (i) the Exchange 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 (as defined in the Exchange Offer) 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 (within the
meaning of the Securities Act) of the Exchange 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 Exchange Notes must
comply with the registration and prospectus delivery requirements of the
Securities Act in connection with a secondary resale transaction of the
Exchange 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 in
the Exchange Offer under the caption "The Exchange Offer--Resales of the
Exchange Notes," (iv) that if the Holder is a broker-dealer holding Initial
Notes acquired for its own account as a result of market-making activities or
other trading activities, it will deliver a prospectus meeting the
requirements of the Securities Act in connection with any resale of Exchange
Notes received in respect of such
 
                                       3
<PAGE>
 
Initial Notes pursuant to the Exchange Offer; provided that the delivery of a
Prospectus in connection with the exchange of Initial Notes by such Holder
will not be deemed an admission that such Holder is an underwriter (within the
meaning of the Securities Act), (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 Regulations S-K of
the Securities Act and (vi) neither the Holder nor any Beneficial Owner is an
"affiliate," as defined under Rule 405 of the Securities Act, of the Company.
 
  In addition, if the undersigned is not a broker-dealer, the undersigned
represents that it is not engaged in, and does not intend to engage in, a
distribution of Exchange Notes. If the undersigned is a broker-dealer holding
Initial Notes acquired for its own account as a result of market-making
activities or other trading activities, it will deliver a prospectus meeting
the requirements of the Securities Act in connection with any resale of
Exchange Notes received in respect of such Initial Notes pursuant to the
Exchange Offer; provided, however, that by so acknowledging and by delivering
a prospectus, the undersigned will not be deemed to admit that it is an
underwriter (within the meaning of the Securities Act).
 
  The Company has agreed, subject to the provisions of the Registration Rights
Agreement, the Prospectus, as it may be amended or supplemented from time to
time, may be used by a Participating Broker-Dealer (as defined below) in
connection with resales of Exchange Notes received in exchange for Initial
Notes, where such Initial Notes were acquired by such broker-dealer for its
own account as a result of market-making activities or other trading
activities, for a period ending 180 days after the Expiration Date [(subject
to extension under certain limited circumstances described in the Prospectus)]
or, if earlier, when all such Exchange Notes have been disposed of by such
participating broker-dealer. In that regard, each broker-dealer who acquired
Initial Notes for its own account as a result of market-making or other
trading activities (a "Participating Broker-Dealer"), by tendering such
Initial Notes and executing this Letter of Transmittal, agrees that, upon
receipt of notice from the Company of the occurrence of any event or the
discovery of any fact which makes any statement contained or incorporated by
reference in the Prospectus untrue in any material respect or which causes the
Prospectus to omit to state a material fact necessary in order to make the
statements contained or incorporated by reference therein, in light of the
circumstances under which they were made, not misleading or of the occurrence
of certain other events specified in the Registration Rights Agreement, such
Participating Broker-Dealer will suspend the sale of Exchange Notes pursuant
to the Prospectus until the Company have amended or supplemented the
Prospectus to correct such misstatement or omission and the Company has
furnished copies of the amended or supplemented Prospectus to the
Participating Broker-Dealer or the Company has given notice that the sale of
the Exchange Notes may be resumed, as the case may be. If the Company gives
such notice to suspend the sale of the Exchange Notes, they shall extend the
180-day period referred to above during which Participating Broker-Dealers are
entitled to use the Prospectus in connection with the resale of Exchange Notes
by the number of days during the period from and including the date of the
giving of such notice to and including the date when Participating Broker-
Dealers shall have received copies of the supplemented or amended Prospectus
necessary to permit resales of the Exchange Notes or to and including the date
on which the Company has given notice that the sale of Exchange Notes may be
resumed, as the case may be.
 
  The undersigned understands and acknowledges that the Company reserves the
right in its sole discretion to purchase or make offers for any Initial Notes
that remain outstanding subsequent to the Expiration Date or as set forth in
the Exchange Offer under the caption "The Exchange Offer--Conditions of the
Exchange Offer," to terminate the Exchange Offer and, to the extent permitted
by applicable law, purchase Initial Notes in the open market, in privately
negotiated transactions or otherwise. The term of any such purchases or offers
could differ from the terms of the Exchange Offer.
 
  The undersigned hereby represents and warrants that the undersigned accepts
the terms and conditions of the Offer, has full power and authority to tender,
exchange, assign and transfer the Initial Notes tendered hereby, and that when
the same are accepted for exchange by the Company, the Company will acquire
good and unencumbered title thereto, free and clear of all liens, restrictions
charges and encumbrances and not subject to
 
                                       4
<PAGE>
 
any adverse claim or right. The undersigned will, upon request, execute and
deliver any additional documents deemed by the Exchange Agent or the Company
to be reasonably necessary or desirable to complete the sale, assignment and
transfer the Initial Notes tendered hereby.
 
  The undersigned agrees that all authority conferred or agreed to be
conferred by this Letter of Transmittal and every obligation of the
undersigned hereunder shall be binding upon the successors, assigns, heirs,
executors, administrations, trustees in bankruptcy and legal representatives
of the undersigned and shall not be affected by, and shall survive, the death
or incapacity of the undersigned.
 
  The undersigned understands that tenders of the Initial Notes pursuant to
any one of the procedures described under "The Exchange Offer--Procedures for
Tendering Initial Notes" in the Exchange Offer and in the instructions hereto
will constitute a binding agreement between the undersigned and the Company in
accordance with the terms and subject to the conditions of the Offer.
 
  The undersigned understands that by tendering Initial Notes pursuant to one
of the procedures describe in the Exchange Offer and the instructions thereto,
the tendering holder will be deemed to have waived the right to receive any
payment in respect of interest on the Initial Notes accrued up to the date of
issuance of the Exchange Notes.
 
  The undersigned recognizes that, under certain circumstances set forth in
the Exchange Offer, the Company may not be required to accept for exchange any
of the Initial Notes tendered. Initial Notes not accepted for exchange or
withdrawn will be returned to the undersigned as the address set forth below
unless otherwise indicated under "Special Delivery Instructions" below.
 
  Unless otherwise indicated herein in the box entitled "Special Exchange
Instructions" below, the undersigned hereby directs that the Exchange Notes be
issued in the name(s) of the undersigned or, in the case of a book-entry
transfer of Initial Notes, that such Exchange Notes be credited to the account
indicated above maintained at DTC. If applicable, substitute certificates
representing the Initial Notes not exchanged or not accepted for exchange will
be issued to the undersigned or, in the case of a book-entry transfer of
Initial Notes, will be credited to the account indicated above maintained at
DTC. Similarly, unless otherwise indicated under "Special Delivery
Instructions," the undersigned hereby directs that the Exchange Notes be
delivered to the undersigned at the address shown below the undersigned's
signature. The undersigned recognizes that the Company has no obligation
pursuant to the "Special Exchange Instructions" to transfer any Initial Notes
from the name of the Registered Holder thereof if the Company does not accept
for exchange any of the principal amount of such Initial Notes so tendered.

                                 INSTRUCTIONS
 
             FORMING PART OF THE TERMS AND CONDITIONS OF THE OFFER
 
  1. DELIVERY OF THIS LETTER OF TRANSMITTAL AND INITIAL NOTES: GUARANTEED
DELIVERY PROCEDURES. To be effectively tendered pursuant to the Offer, the
Initial Notes, together with a properly completed Letter of Transmittal (or
manually signed facsimile hereof) duly executed by the Registered Holder
thereof, and any other documents required by this Letter of Transmittal must
be received by the Exchange Agent at one of its addresses set forth on the
front page of this Letter of Transmittal and tendered Initial Notes must be
received by the Exchange Agent at one of such addresses on or prior to the
Expiration Date; provided, however, that book-entry transfers of Initial Notes
may be effected in accordance with the procedures set forth in the Exchange
Offer under the caption "The Exchange Offer--Procedures For Tendering Initial
Notes--Book-Entry Delivery." If the Beneficial Owner of any Initial Notes is
not the Registered Holder, then such person may validly tender such person's
Initial Notes only by obtaining and submitting to the Exchange Agent a
properly completed Letter of Transmittal from the Registered Holder. LETTERS
OF TRANSMITTAL OF INITIAL NOTES SHOULD BE DELIVERED ONLY BY HAND OR BY
COURIER, OR TRANSMITTED BY MAIL, AND ONLY TO THE EXCHANGE AGENT AND NOT TO THE
COMPANY OR TO ANY OTHER PERSON.
 
  THE METHOD OF DELIVERY OF INITIAL NOTES AND ALL OTHER REQUIRED DOCUMENTS TO
THE EXCHANGE AGENT IS AT THE ELECTION AND RISK OF THE HOLDER, AND IF SUCH
DELIVERY IS BY MAIL, IT IS SUGGESTED THAT THE HOLDER USE PROPERLY INSURED,
REGISTERED MAIL WITH RETURN RECEIPT REQUESTED. IF INITIAL NOTES ARE SENT BY
MAIL, IT IS SUGGESTED THAT THE MAILING BE MADE SUFFICIENTLY IN ADVANCE OF THE
EXPIRATION DATE TO PERMIT DELIVERY TO THE EXCHANGE AGENT PRIOR TO 5:00 P.M.,
NEW YORK CITY TIME, ON THE EXPIRATION DATE.
 
  If a holder desires to tender Initial Notes and such holder's Initial Notes
are not immediately available or time will not permit such holder to complete
the procedures for book-entry transfer on a timely basis or time will not
permit such holder's Letter of Transmittal and other required documents to
reach the Exchange Agent on or before the Expiration Date, such holder's
tender may be effected if:
 
    (a) such tender is made by or through an Eligible Institution (as defined
  below);
 
    (b) on or prior to the Expiration Date, the Exchange Agent has received a
  telegram, facsimile transmission or letter form such Eligible Institution
  setting forth the name and address of the holder of such Initial Notes, the
  certificate number(s) of such Initial Notes (except in the case of book-
  entry tenders) and the principal amount of Initial Notes tendered and
  stating that the tender is being made thereby and guaranteeing that, within
  three business days after the Expiration Date, a duly executed Letter of
  Transmittal, or facsimile thereof, together with the Initial Notes, and any
  other documents required by this Letter of Transmittal and Instructions,
  will be deposited by such Eligible Institution with the Exchange Agent; and
 
    (c) this Letter of Transmittal, or a manually signed facsimile hereof,
  and Initial Notes, in proper form for transfer (or a Book-Entry
  confirmation with respect to such Initial Notes), and all other required
  documents are received by the Exchange Agent within three business days
  after the Expiration Date.
 
  2. WITHDRAWAL OF TENDERS. Tendered Initial Notes may be withdrawn at any
time prior to 5:00 p.m., New York City time, on the Expiration Date.
 
  To be effective, a written, telegraphic or facsimile transmission notice of
withdrawal must (i) be timely received by the Exchange Agent at one of its
addresses set forth on the first page of this Letter of Transmittal before the
Exchange Agent receives notice of acceptance from the Company, (ii) specify
the name of the person who tendered the Initial Notes, (iii) contain the
description of the Initial Notes to be withdrawn, the certificate number(s) of
such Initial Notes (except in the case of book-entry tenders) and the
aggregate principal amount represented by such Initial Notes or a Book-Entry
Confirmation with respect to such Initial Notes, and (iv) be
 
                                      11
<PAGE>
 
signed by the holder of such Initial Notes in the same manner as the original
signature appears on this Letter of Transmittal (including any required
signature guarantees) or be accompanied by evidence satisfactory to the
Company that the person withdrawing the tender has succeeded to the beneficial
ownership of the Initial Notes. The signature(s) on the notice of withdrawal
must be guaranteed by an Eligible Institution unless such Initial Notes have
been tendered (i) by a Registered Holder (which term for purposes of this
document shall include any participant tendering by book-entry transfer) of
Initial Notes who has not completed either the box entitled "Special Exchange
Instructions" or the box entitled "Special Delivery Instructions" on this
Letter of Transmittal or (ii) for the account of an Eligible Institution. If
the Initial Notes have been tendered pursuant to the procedure for book-entry
tender set forth in the Exchange Offer under the caption "Procedure for
Tendering Initial Notes," a notice of withdrawal is effective immediately upon
receipt by the Exchange Agent of a written, telegraphic or facsimile
transmission notice of withdrawal even if physical release is not yet
effected. In addition, such notice must specify, in the case of Initial Notes
tendered by delivery of such Initial Notes, the name of the Registered Holder
(if different from that of the tendering holder) to be credited with the
withdrawn Initial Notes. Withdrawals may not be rescinded, and any Initial
Notes withdrawn will thereafter be deemed not validly tendered for purposes of
the Offer. However, properly withdrawn Initial Notes may be retendered by
following one of the procedures described under "The Exchange Offer--
Procedures for Tendering Initial Notes" in the Exchange Offer at any time on
or prior to the applicable Expiration Date.
 
  3. SIGNATURES ON THIS LETTER OF TRANSMITTAL, BOND POWERS AND ENDORSEMENTS;
GUARANTEE OF SIGNATURES. If this Letter of Transmittal is signed by the
Registered Holder of the Initial Notes tendered hereby, the signature must
correspond exactly with the name as written on the face of the Initial Notes
without any change whatsoever.
 
  If any Initial Notes tendered hereby are owned of record by two or more
joint owners, all such owners must sign this Letter of Transmittal.
 
  If any Initial Notes tendered hereby are registered in different names, it
will be necessary to complete, sign and submit as many separate copies of this
Letter of Transmittal as there are different registrations of Initial Notes.
 
  When this Letter of Transmittal is signed by the Registered Holder or
Holders specified herein and tendered hereby, no endorsements of such Initial
Notes or separate bond powers are required. If, however, Exchange Notes are to
be issued, or any untendered principal amount of Initial Notes are to be
reissued to a person other than the Registered Holder, then endorsements of
any Initial Notes transmitted hereby or separate bond powers are required.
 
  If this Letter of Transmittal is signed by a person other than the
Registered Holder or Holders, such Initial Notes must be endorsed or
accompanied by appropriate bond powers, in either case signed exactly as the
name or names of the Registered Holder or Holders appear(s) on the Initial
Notes.
 
  If this Letter of Transmittal or a Notice of Guaranteed Delivery or any
Initial Notes or bond powers are signed by trustees, executors,
administrators, guardians, attorneys-in-fact, officers of corporations or
others acting in a fiduciary or representative capacity, such persons should
so indicate when signing, and, unless waived by the Company, proper evidence
satisfactory to the Company of their authority so to act must be submitted.
 
  Except as describe in this paragraph, signatures on this Letter of
Transmittal or a notice of withdrawal, as the case may be, must be guaranteed
by an Eligible Institution which is a firm which is a member of a registered
national securities exchange or the National Association of Securities
Dealers, Inc., 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 (each
an "Eligible Institution"). Signatures on this Letter of Transmittal or a
notice of withdrawal, as the case may be, need not be guaranteed if the
Initial Notes tendered pursuant hereto are tendered (i) by a Registered Holder
of Initial Notes who has not completed either the box entitled "Special
Exchange Instructions" or the box entitled "Special Delivery Instructions" on
this Letter of Transmittal or (ii) for the account of an Eligible Institution.
 
                                      12
<PAGE>
 
  Endorsement on Initial Notes or signatures on bond forms required by this
Instruction 3 must be guaranteed by an Eligible Institution.
 
  4. SPECIAL ISSUANCE AND DELIVERY INSTRUCTIONS. Tendering holders should
indicate in the applicable box the name and address to which Exchange Notes
and/or substitute Initial Notes for the principal amounts not exchanged are to
be issued or sent, if different from the name and address of the person
signing this Letter of Transmittal. In the case of issuance in a different
name, the employer identification or social security number of the person
named must also be indicated. If no such instructions are given, such Initial
Notes not exchanged will be returned to the name and address of the person
signing this Letter of Transmittal.
 
  5. TAXPAYER IDENTIFICATION NUMBER AND BACKUP WITHHOLDING. Federal income tax
law of the United States requires that a holder of Initial Notes whose Initial
Notes are accepted for exchange provide the Company with such holder's correct
taxpayer identification number, which, in the case of a holder who is an
individual, is the holder's social security number, or otherwise establish an
exemption from backup withholding. If the Company is not provided with the
holder's correct taxpayer identification number, the exchanging holder of
Initial Notes may be subject to a penalty imposed by the Internal Revenue
Service. In addition, interest on the Exchange Notes acquired pursuant to the
Offer may be subject to backup withholding in an amount equal to 31 percent of
any interest payment. If withholding occurs and results in an overpayment of
taxes, a refund may be obtained from the Internal Revenue Service by filing a
return.
 
  To prevent backup withholding, each exchanging holder of Initial Notes
subject to backup withholding must provide his correct taxpayer identification
number by completing the Substitute Form W-9 provided in this Letter of
Transmittal, certifying that the taxpayer identification number provided is
correct (or that the exchanging holder of Initial Notes is awaiting a taxpayer
identification number) and that either (a) the exchanging holder has not been
notified by the Internal Revenue Service that he is subject to backup
withholding as a result of failure to report all interest or dividends or (b)
the Internal Revenue Service has notified the exchanging holder that he is no
longer subject to backup withholding.
 
  Certain exchanging holders of Initial Notes (including, among others, all
corporations and certain foreign individuals) are not subject to these backup
withholding requirements. A foreign individual and other exempt holders (e.g.,
corporations) should certify, in accordance with the enclosed Guidelines for
Certification of Taxpayer Identification Number on Substitute Form W-9, to
such exempt status on the Substitute Form W-9 provided in this Letter of
Transmittal. Nonresident aliens should submit Form W-8, available from the
Exchange Agent upon request.
 
  6. TRANSFER TAXES. Holders tendering pursuant to the Offer will not be
obligated to pay brokerage commissions or fees or to pay transfer taxes with
respect to their exchange under the Offer unless the box entitled "Special
Issuance Instructions" in this Letter of Transmittal has been completed, or
unless the securities to be received upon exchange are to be issued to any
person other than the holder of the Initial Notes tendered for exchange. The
Company will pay all other charges or expenses in connection with the Offer.
If holders tender Initial Notes for exchange and the Offer is not consummated,
such Initial Notes will be returned to the holders at the Company expense.
 
  Except as provided in this Instruction 6, it will not be necessary for
transfer tax stamps to be affixed to the Initial Notes specified in this
Letter of Transmittal.
 
  7. INADEQUATE SPACE. If the space provided herein is inadequate, the
aggregate principal amount of the Initial Notes being tendered and the
security numbers (if available) should be listed on a separate schedule
attached hereto and separately signed by all parties required to sign this
Letter of Transmittal.
 
  8. PARTIAL TENDERS. Tenders of Initial Notes will be accepted only in
integral multiples of $1,000. If tenders are to be made with respect to less
than the entire principal amount of any Initial Notes, fill in the principal
amount of Initial Notes which are tendered in column (iv) of the "Description
of Initial Notes." In the
 
                                      13
<PAGE>
 
case of partial tenders, the Initial Notes in fully registered form for the
remainder of the principal amount of the Initial Notes will be sent to the
persons(s) signing this Letter of Transmittal, unless otherwise indicated in
