be antidilutive.


ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
         RESULTS OF OPERATIONS

      The following discussion of the financial condition and results of
operations of the Company should be read in conjunction with the
Management's Discussion and Analysis of Financial Condition and Results of
Operations and the Consolidated Financial Statements and the Notes thereto
included in the Company's Annual Report on Form 10-K for the year ended
December 31, 1999. This quarterly report on Form 10-Q contains
forward-looking statements within the meaning of Section 27A of the
Securities Act of 1933, as amended, and Section 21E of the Securities
Exchange Act of 1934, as amended. These forward-looking statements involve
risks and uncertainties and actual results could differ materially from
those discussed in the forward-looking statements. All forward-looking
statements and risk factors included in this document are made as of the
date hereof, based on information available to the Company as of the date

SIX MONTHS ENDED JUNE 30, 2000 COMPARED TO SIX MONTHS ENDED JUNE 30, 1999

Revenues

      Affiliates. Revenues from affiliates were $9.4 million for the six
months ended June 30, 2000 compared to $3.1 million for the six months
ended June 30, 1999, an increase of $6.3 million or 203.2%. The increase in
revenues from affiliates was due to an increase in sales of calling card
products through our affiliate RSL COM USA. Additionally, the increase in
sales to RSL COM was also facilitated by the growth in our network
resulting in our ability to provide additional capacity to RSL COM and an
increase in demand for our services from RSL COM offset by decreases in
prices.

      Non-affiliates. Revenues from non-affiliates were $5.0 million for
the six months ended June 30, 2000 compared to $1.2 million for the six
months ended June 30, 1999, an increase of $3.8 million or 316.7 %.
Revenues from carrier transmission services for telecommunications carriers
other than RSL COM were $850,863 for the six months ended June 30, 2000
compared to $489,723 for the six months ended June 30, 1999, an increase of
$361,140 or 73.7 %. The increase was due primarily to an increased demand
from a larger customer base. Revenues from enhanced IP communications
services were $3.9 million for the six months ended June 30, 2000 compared
to $652,580 for the six months ended June 30, 1999, an increase of $3.2
million or 494.1%. The increase in revenues from enhanced IP communications
services was due to integration service fees received from online partners
as well as a greater number of PC-to-phone and phone-to-phone calls being
placed by an increasing user base.

      Revenues from carrier transmission services to RSL COM and other
telecommunications carriers accounted for 28.6% and 83.5% of revenues for
the periods ended June 30, 2000 and June 30, 1999, respectively. Other than
RSL COM, no other customer accounted for greater than 10% of the Company's
revenues during these periods. The Company expects that revenues from
carrier transmission services to RSL COM and other carriers will continue
to account for a majority of its revenues through at least the end of 2000.

Costs and Operating Expenses

      Cost of revenues. Cost of revenues were $11.9 million for the six
months ended June 30, 2000 compared to $3.3 million for the six months
ended June 30,1999. The increase in cost of revenues was due primarily to
an increase in the amount of traffic being terminated.

      Research and development expenses. Research and development expenses
were $2.8 million for the six months ended June 30, 2000 compared to $0.4
million for the six months ended June 30, 1999. The increase in research
and development expenses was due to greater costs incurred in hiring
additional personnel to develop new services and enhancements to the
Company's existing services.

      Selling and marketing expenses. Selling and marketing expenses were
$11.0 million for the six months ended June 30, 2000 compared to $1.5
million for the six months ended June 30, 1999, an increase of $9.5 million
or 633.3%. The increase in selling and marketing expenses was due to a
significant increase in branding costs, promotional activities and
personnel to support the expansion of such marketing and promotional
activities.

      General and administrative expenses. General and administrative
expenses (exclusive of non-cash compensation expenses) were $2.8 million
for the six months ended June 30, 2000 compared to $1.4 million for the six
months ended June 30, 1999, an increase of $1.4 million or 100.0%. The
increase in general and administrative expenses was primarily due to hiring
additional personnel and increased occupancy costs. The Company expects
that general and administrative expenses will continue to increase as
additional personnel are recruited to support the Company's growth.

      Non-cash compensation expenses. Non-cash compensation expenses were
$4.2 million for the six months ended June 30, 2000 compared to $2.1
million for the six months ended June 30, 1999, an increase of $2.1 million
or 100%. The increase in non-cash compensation expenses was due to the
amortization of costs incurred with the 1997, 1998 and 1999 grants of
options and warrants below the then fair market value.

      Depreciation and amortization of goodwill. Depreciation and
amortization of goodwill was $3.3 million for the six months ended June 30,
2000 compared to $1.5 million for the six months ended June 30, 1999, an
increase of $1.8 million or 120.0%. The increase in depreciation and
amortization of goodwill was due to the continued increase in the Company's
fixed assets and the acquisition of YourDay.com, Inc. during the first
quarter of 2000.

Loss from Operations

      Loss from operations was $21.5 million for the six months ended June
30, 2000 compared to $6.0 million for the six months ended June 30, 1999,
an increase of $15.5 million or 258.3%. The increase in loss from
operations was due primarily to the increase in costs and operating
expenses, including non-cash compensation expenses and sales and marketing
expenses, as well as a decrease in prices the Company charged for carrier
transmission services. The Company expects to continue to incur losses for
the foreseeable future.

Interest Income (Expense), Net

      Interest income, net was $1.9 million for the six months ended June 30,
2000 compared to interest expense of $0.76 million for the six months ended
June 30, 1999, an increase of $2.7 million. The increase in interest income
was primarily due to interest earned on the remaining proceeds from the
Company's initial public offering. The Company incurs interest expense in
connection with its borrowings from RSL COM.

Net Loss

      Net loss was $19.6 million for the six months ended June 30, 2000
compared to $6.8 million for the six months ended June 30, 1999, an
increase of $12.8 million or 188%. The increase in net loss was due to the
foregoing factors.

THREE MONTHS ENDED JUNE 30, 2000 COMPARED TO THREE MONTHS ENDED JUNE 30, 1999

Revenues

      Affiliates. Revenues from affiliates were $4.6 million for the three
months ended June 30, 2000 compared to $1.5 million for the three months
ended June 30, 1999, an increase of $3.1 million or 206.7%. The increase in
revenues from affiliates was due to an increase in sales of calling card
products through our affiliate RSL COM USA. Additionally, the increase in
sales to RSL COM was also facilitated by the growth in our network
resulting in our ability to provide additional capacity to RSL COM and an
increase in demand for our services from RSL COM offset by decreases in
prices.

      Non-affiliates. Revenues from non-affiliates were $3.2 million for
the three months ended June 30, 2000 compared to $0.67 million for the
three months ended June 30, 1999, an increase of $2.5 million or 376.9%.
Revenues from carrier transmission services for telecommunications carriers
other than RSL COM were $316,521 for the three months ended June 30, 2000
compared to $312,983 for the three months ended June 30, 1999, an increase
of $3,538 or 1.1%. Revenues from enhanced IP communications services were
$2.7 million for the three months ended June 30, 2000 compared to $388,044
for the three months ended June 30, 1999, an increase of $2.3 million or
585.1%. The increase in revenues from enhanced IP communications services
was due to integration service fees received from online partners as well
as a greater number of PC-to-phone and phone-to-phone calls being placed by
an increasing user base.

      Revenues from carrier transmission services to RSL COM and other
telecommunications carriers accounted for 24.4% and 83.4% of revenues for
the periods ended June 30, 2000 and June 30, 1999, respectively. Other than
RSL COM, no other customer accounted for greater than 10% of the Company's
revenues during these periods. The Company expects that revenues from
carrier transmission services to RSL COM and other carriers will continue
to account for a majority of its revenues through at least the end of 2000.

Costs and Operating Expenses

      Cost of revenues. Cost of revenues were $6.2 million for the three
months ended June 30, 2000 compared to $1.6 million for the three months
ended June 30, 1999. The increase in cost of revenues was due primarily to
an increase in the amount of traffic being terminated.

      Research and development expenses. Research and development expenses
were $1.6 million for the three months ended June 30, 2000 compared to
$0.35 million for the three months ended June 30, 1999. The increase in
research and development expenses was due to greater costs incurred in
additional hiring personnel to develop new services and enhancements to the
Company's existing services.

      Selling and marketing expenses. Selling and marketing expenses were
$6.1 million for the three months ended June 30, 2000 compared to $0.85
million for the three months ended June 30, 1999, an increase of $5.3
million or 621.0%. The increase in selling and marketing expenses was due
to a significant increase in branding costs, promotional activities and
personnel to support the expansion of such marketing and promotional
activities.

      General and administrative expenses. General and administrative
expenses (exclusive of non-cash compensation expenses) were $1.7 million
for the three months ended June 30, 2000 compared to $0.9 million for the
three months ended June 30, 1999, an increase of $0.8 million or 89.0%. The
increase in general and administrative expenses was primarily due to hiring
additional personnel and increased occupancy costs. The Company expects
that general and administrative expenses will continue to increase as
additional personnel are recruited to support the Company's growth.

      Non-cash compensation expenses. Non-cash compensation expenses were
$1.8 million for the three months ended June 30, 2000 compared to $1.9
million for the three months ended June 30, 1999, a decrease of $0.1

amortization of goodwill was $1.9 million for the three months ended June
30, 2000 compared to $0.5 for the three months ended June 30, 1999, an
increase of $1.4 million or 280.0%. The increase in depreciation and
amortization of goodwill was due to the continued increase in the Company's
fixed assets and the acquisition of YourDay.com, Inc. during the first
quarter of 2000.

Loss from Operations

      Loss from operations was $11.3 million for the three months ended
June 30, 2000 compared to $3.9 million for the three months ended June 30,
1999, an increase of $7.4 million or 189.7%. The increase in loss from
operations was due primarily to the increase in costs and operating
expenses, including non-cash compensation expenses and sales and marketing
expenses, as well as a decrease in prices the Company charged for carrier
transmission services. The Company expects to continue to incur losses for
the foreseeable future.

Interest Income (Expense), Net

      Interest income, net was $0.98 million for the three months ended
June 30, 2000 compared to interest expense of $0.60 million for the three
months ended June 30, 1999, an increase of $1.58 million. The increase in
interest income was primarily due to interest earned on the remaining
proceeds from the Company's initial public offering. The Company incurs
interest expense in connection with its borrowings from RSL COM.

Net Loss

      Net loss was $10.3 million for the three months ended June 30, 2000
compared to $4.5 million for the three months ended June 30, 1999, an
increase of $5.8 million or 128.9%. The increase in net loss was due to the
foregoing factors.

LIQUIDITY AND CAPITAL RESOURCES

      As of June 30, 2000, the Company had cash and cash equivalents of
approximately $15.2 million, marketable securities-available for sale of
approximately $66.0 million and working capital of approximately $65.9
million. The Company generated negative cash flow from operating activities
of approximately $13.5 million during the six months ended June 30, 2000
compared with negative cash flow from operating activities of $3.0 million
during the six months ended June 30, 1999. Accounts receivable were
approximately $2.4 million and $1.0 million at June 30, 2000 and June 30,
1999, respectively. Accounts receivable and accounts payable have increased
from period to period as the Company's business has grown.

      The Company's capital expenditures increased from approximately $0.9
million in the six months ended June 30, 1999 compared to approximately
$5.2 million in the six months ended June 30, 2000, as the Company expanded
its domestic and international network infrastructure.

      The Company registered 6,900,000 of its Class A common Stock on a
Form S-1 registration statement, which became effective on November 22,
1999. The Company received net proceeds, after deducting underwriting
discounts and commissions and offering expenses, of approximately
$96,255,000 from the sale of 6,900,000 at the initial public offering price
of $15.00 per share on November 29, 1999.

      The Company believes that its available cash and cash equivalents
will be sufficient to meet its working capital requirements, including
operating losses, and capital expenditure requirements for at least the
next 18 months, assuming the Company's business plan is implemented
successfully. Thereafter, the Company will be required to raise additional
funds. Additional financing may not be available when needed or, if
available, such financing may not be on terms favorable to the Company. If
additional funds are raised through the issuance of equity securities, the
Company's existing stockholders may experience significant dilution. In
addition, the indentures governing outstanding indebtedness of RSL COM
restrict the Company's ability to incur indebtedness. The Company also has
agreed with RSL COM not to incur any debt (other than inter-company debt)
without its written consent so long as the Company is a restricted
subsidiary of RSL COM. Those limitations may require the Company to resort
to other sources of funding, such as the issuance of equity, and the
Company may need to rely upon RSL COM to provide any additional capital to
meet its working capital and capital expenditure requirements, and the
Company cannot assure you that RSL COM or any other third party will be
willing or able to provide additional capital on favorable terms or at all.

ITEM 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

      The Securities and Exchange Commission's rule related to market risk
disclosure requires that the Company describe and quantify its potential
losses from market risk sensitive instruments attributable to reasonably
possible market changes. Market risk sensitive instruments include all
financial or commodity instruments and other financial instruments (such as
investments and debt) that are sensitive to future changes in interest
rates, currency exchange rates, commodity prices or other market factors.
The Company believes its exposure to market risk is immaterial. The Company
currently does not invest in, or otherwise hold, for trading or other
purposes, any financial instruments subject to market risk.


                                  PART II
                             OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

      On October 8, 1999, Aerotel, Ltd. and Aerotel U.S.A. commenced a suit
against us, RSL COM and an RSL COM subsidiary in the United States District
Court for the Southern District of New York. Aerotel alleges that we are
infringing on a patent issued to Aerotel in November 1987 by making, using,
selling and offering for sale prepaid telephone card products in the United
States. Aerotel seeks an injunction to stop us from using the technology
covered by this patent, monetary damages in an unspecified amount and
reimbursement of attorneys' fees. We have answered the complaint, and the
parties are currently engaged in pre-trial discovery. As we continue to
evaluate these claims, we believe that we have meritorious defenses to the
claims and we intend to defend the lawsuit vigorously. However, the outcome
of the litigation is inherently unpredictable and an unfavorable result may
have a material adverse effect on our business, financial condition and
results of operations. Regardless of the ultimate outcome, the litigation
could result in substantial expenses to us and significant diversion of
efforts by our managerial and other personnel.

      The Company is not a party to any other material litigation and are
not aware of any other pending or threatened litigation that could have a
material adverse effect on us or our business taken as a whole.


ITEM 2.  CHANGE IN SECURITIES AND USE OF PROCEEDS

      On November 22, 1999, the Company offered 6,900,000 shares of its
Class A common stock in an initial public offering. These shares were
registered with the Securities and Exchange Commission on a registration
statement on Form S-1 (file no. 333-86503), which became effective on
November 22, 1999. The Company received net proceeds of approximately
$96,255,000 from the sale of 6,900,000 shares at the initial public
offering price of $15.00 per share after deducting underwriting commissions
and discounts and expenses of approximately $6,300,000. The managing
underwriters for the initial public offering were Lehman Brothers Inc.,
Merrill Lynch & Co., U.S. Bancorp Piper Jaffray, Lazard Freres & Co. LLC
and Fidelity Capital Markets.

      As of the date of this report, the Company has used approximately
$66.0 million of the cash proceeds to purchase marketable government
securities. We have not otherwise made any specific allocations with
respect to the net proceeds from the initial public offering. The Company
expects that it will use the net proceeds to be allocated as follows:

o    approximately $20 million to fund marketing and promotional
     activities;

o    approximately $10 million for capital expenditures; and

o    the balance for general corporate purposes

      The preceding allocations are only an estimate and the amounts that
the Company actually expends will depend upon several factors, including
its available cash, the success of the Company's marketing and promotional
activities and the availability of new business opportunities. Pending use
of the net proceeds, the Company intends to invest the net proceeds in
interest-bearing, investment-grade instruments, certificates of deposit, or
direct or guaranteed obligations of the United States.


ITEM 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

      The Company's Annual Meeting of Stockholders (the "Meeting") was held
on June 13, 2000. The following matters were submitted to the Company's
