                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


(1) GENERAL

The financial statements included herein are unaudited and have been prepared in
accordance with generally accepted accounting principles for interim financial
reporting and Securities Exchange Commission ("SEC") regulations. Certain
information and footnote disclosures normally included in 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 a normal and
recurring nature) which are necessary to present fairly the financial position,
results of operations, stockholders' equity and cash flows for the interim
periods. These financial statements should be read in conjunction with the
audited financial statements for the year ended December 31, 1996, and the
unaudited financial statements for the quarter ended March 31, 1997, each as set
forth in the Registration Statement on Form S-1 of STAR Telecommunications, Inc.
("STAR" or the "Company") Registration No. 333-21325, which was declared
effective by the SEC on June 12, 1997, and with the Company's Quarterly Report
on Form 10-Q for the quarter ended June 30, 1997. The results for the three and
nine month periods ended September 30, 1997 are not necessarily indicative of
the results that may be expected for the year ending December 31, 1997.


(2) BUSINESS AND PURPOSE

Star is an international long distance service provider offering low cost
switched voice services on a wholesale basis primarily to U. S.-based long
distance carriers. Star provides international long distance service to over 275
foreign countries through a flexible network of resale arrangements with long
distance providers, various foreign termination relationships, international
gateway switches and leased and owned transmission facilities.


(3) NET INCOME PER COMMON SHARE

Net income per common share for the three and nine month periods ended September
30, 1996 and 1997 is based on the weighted average number of common shares
outstanding giving effect of the conversion of the preferred stock (Note 4). Per
share information was computed pursuant to the rules of the SEC, which require
that common shares issued by the Company during the twelve months immediately
preceding the Company's initial public offering plus the number of shares
issuable pursuant to the grant of options issued during the same period, be
included in the calculation of the shares outstanding using the treasury stock
method from the beginning of all periods presented.

The following schedule summarizes the information used to compute weighted
average number of common shares outstanding at September 30, 1996 and 1997 (in
thousands):

In February 1997, the Financial Accounting Standards Board introduced SFAS No.
128 "Earnings per Share" and SFAS No. 129 "Disclosure of Information About
Capital Structure". SFAS No. 128 revises and simplifies the computation of
earnings per share and requires certain additional disclosures. SFAS No. 129
requires additional disclosure regarding the Company's capital structure. Both
standards will be adopted in the fourth quarter of the fiscal year 1997.
Management does not expect the adoption of SFAS No. 129 to have a material
effect on the Company's financial position or results of operations. The Company
has not yet evaluated the impact of adopting SFAS No. 128 on earnings per share.


(4) SIGNIFICANT EVENTS

In June 1997, the Company completed an initial public offering of 4,600,000
shares of common stock of which 3,950,000 were sold by the Company and 650,000
shares were sold by certain selling shareholders. The net proceeds to the
Company (after deducting underwriting discounts and offering expenses) from the
sale of the shares was approximately $30.9 million. Through September 30, 1997,
the Company used approximately $18.0 million of the net proceeds from the
initial public offering. Approximately $14.2 million was used to repay
indebtedness, $2.8 million was used to purchase switching and transmission
related equipment and $979,000 was used to finance the Company's operations of
the U.K. subsidiary. The Company intends to use the remaining proceeds to
finance the expansion of its international network facilities, to invest in
direct termination arrangements, strategic alliances or acquisitions and for
working capital and general corporate purposes. In connection with the initial
public offering, all outstanding preferred shares were converted to common
shares at a rate of three preferred shares to two common shares.

The Company entered into an agreement to acquire LD Services, Inc., a long
distance provider which focuses on commercial customers and has programs which
sell to customers with strong international usage. Under the terms of the
definitive agreement, LD Services stockholders will receive 500,000 shares of
STAR common stock, subject to adjustment. The acquisition will be accounted for
as a pooling of interests and the Company expects the transaction to be
completed in the fourth quarter of 1997.


(5) COMMITMENTS

The Company is obligated under various service agreements with long distance
carriers to pay minimum usage charges of approximately $9,320,000 for the three
month period between October 1, 1997 and December 31, 1997, and $30,951,000 and
$5,626,000 for the twelve months ending December 31, 1998 and 1999,
respectively. The Company anticipates exceeding the minimum usage volume with
these vendors.

During the three months ended September 30, 1997, the Company entered into
various foreign exchange contracts to match transactions denominated in foreign
currencies. At September 30, 1997, approximately $840,000 of foreign currency
contracts were outstanding, maturing through March 1998.


(6) STATEMENTS OF CASH FLOWS

During the nine month periods ended September 30, 1996 and 1997, cash paid for
interest was $339,000 and $1,082,000, respectively. For the same periods, cash
paid for income taxes amounted to $1,210,000 and $2,635,000, respectively.

(7) SUBSEQUENT EVENTS

Effective as of September 30, 1997, the Company executed an agreement with Sanwa
Bank, California for a $25 million, 2 year revolving line of credit. The
facility which has certain financial and non-financial covenants is limited to
75% of eligible Accounts Receivable and will be secured by substantially all of
the assets of the Company. The credit facility provides for borrowings at an
interest rate based upon the Bank's cost of funds plus 1.75% and will be used to
support letters of credit and for working capital and general corporate
purposes.



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

This Quarterly Report on Form 10-Q contains certain 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. Forward-looking
statements are statements other than historical information or statements of
current condition. Some forward looking statements may be identified by use of
such terms as "believes", "anticipates", "intends", or "expects". These
forward-looking statements relate to the plans, objectives and expectations of
the Company for future operations. In light of the risks and uncertainties
inherent in all such projected operation matters, the inclusion of
forward-looking statements in this report should not be regarded as a
representation by the Company or any other person that the objectives or plans
of the Company will be achieved or that any of the Company's operating
expectations will be realized. The Company's revenues and results of operations
are difficult to forecast and could differ materially from those projected in
the forward-looking statements contained in this report as a result of numerous
factors including among others, the following: (i) changes in customer rates per
minute; (ii) foreign currency fluctuations; (iii) termination of certain service
agreements or inablility to enter into additional service agreements; (iv)
inaccuracies in the Company's forecast of traffic growth; (v) changes in or
developments under domestic or foreign laws, regulations, licensing requirements
or telecommunications standards; (vi) foreign political or economic instability;
(vii) changes in the availability of transmission facilities; (viii) loss of the
services of key officers; (ix) loss of a customer which provides significant
revenues to the Company; (x) highly competitive market conditions in the
industry, (xi) concentration of credit risk. The foregoing review of the
important factors should not be considered as exhaustive; the Company undertakes
no obligation to release publicly the results of any future revisions it may
make to forward-looking statements to reflect events or circumstances after the
date hereof or to reflect the occurrence of unanticipated events.

Three Months Ended September 30, 1997 Compared to Three Months Ended September
30, 1996.

Revenues: Revenues increased 44.7% to $88.5 million in the third quarter of 1997
from $61.2 million in the third quarter of 1996. Minutes of use increased 59.1%
to 219.6 million in the third quarter of 1997, as compared to 138.0 million
minutes of use in the comparable quarter of the year prior. The average rate per
minute of use declined to $0.40 for the current quarter as compared to $0.44 for
the quarter ended September 30, 1996. The increase in revenue resulted from
increased usage by existing customers offset by a lower average customer rate
per minute. The average customer rate per minute fell due to price decreases in
selected countries combined with increases in traffic terminating to lower
priced countries. As global deregulation continues to open up new countries to
competition for long distance telecommunication services, management expects
revenue growth to be driven by prevailing trends of accelerated growth in
international traffic volumes coupled with declining customer rates per minute,
although there can be no assurance in that regard.

Gross Margin: Gross profit increased to $10.4 million in the third quarter of
1997 from $4.6 million in the third quarter of 1996. Gross margin improved to
11.7% from 7.6% reflecting the negotiation of lower rates on routes with
significant traffic as well as lower costs on direct termination arrangements in
selected countries.

Selling, General and Administrative: Selling, general and administrative
expenses increased 75.1% to $6.4 million during the third quarter of 1997 from
$3.7 million in the comparable quarter one year earlier, and increased as a
percentage of revenue to 7.2% from 6.0% in the prior period. Selling, general
and administrative expenses increased between comparable periods as the Company
continues to increase its employee base and incurs payroll, employee benefits,
commissions and related expenses. Operating expenses associated with expanding
transmission and switch facilities also increased in support of the Company's
growing telecommunications network. Bad debt expense remained stable as a
percentage of revenues at 1.5%. The planned buildout of the Company's network
includes switch sites in Dallas, Miami, 



                                       12

Chicago and Seattle. The establishment of licensed carrier operations in Germany
and Australia will continue to increase the Company's operating expenses related
to revenues.

Depreciation: Depreciation increased to $1.1 million in the third quarter of
1997 from $343,000 in the third quarter of 1996. Depreciation increased as a
result of the Company's continued expansion of its transmission network,
leasehold improvements associated with the Los Angeles, New York and London
switching facilities and switch site buildout.

Other Income (Expense): Other expense, net, increased slightly to $134,000 in
the third quarter of 1997 from $131,000 in the third quarter of 1996. Interest
expense grew to $419,000 in the third quarter of 1997 from $173,000 in the third
quarter of 1996 as a result of increased financing for switches, undersea cables
and other property and equipment. Interest income of $285,000 was earned in the
third quarter of 1997 on the invested balance of proceeds remaining from the
initial public offering.

Provision for Income Taxes: The Company's provision for income taxes increased
to $1.3 million in the third quarter of 1997 from $217,000 in the third quarter
of 1996 reflecting strong growth in pre-tax earnings.

Nine Months Ended September 30, 1997 Compared to Nine Months Ended September 30,
1996.

Revenues: Revenues increased 73.4% to $242.2 million in the nine month period
ending September 30, 1997 from $139.7 million for the comparable period of the
prior year. Minutes of use increased to 77.4% to 580.8 million in the first nine
months of 1997 from 327.4 million in the first nine months of 1996. The increase
reflects both increased sales to existing customers as well as an increase in
the number of wholesale carrier customers offset by a slight decrease in the
average customer rate per minute.

Gross Margin: Gross profit increased to $26.9 million in the nine month period
ending September 30, 1997 from $12.1 million for the same period of the prior
year. Gross margin improved to 11.1% from 8.7%, reflecting the negotiation of
lower rates on routes with significant traffic and the benefit of the Company's
lower cost direct termination arrangements.

Selling, General and Administrative: Selling, general and administrative
expenses increased 111.2% to $17.0 million during the first nine months of 1997
from $8.0 million in the comparable period one year earlier, and increased as a
percentage of revenue to 7.0% from 5.8% in the prior period. Selling, general
and administrative expenses increased between comparable periods as the Company
continues to expand its employee base and incurs payroll, employee benefits,
commissions and related expenses. Operating expenses associated with expanding
transmission and switch facilities also increased in support of the Company's
growing telecommunications network. Bad debt expense increased as a percentage
of revenues to 1.7% from 1.4%.

Depreciation: Depreciation increased to $2.7 million in the first nine months of
1997 from $607,000 in the first nine months of 1996. Depreciation increased as a
result of the Company's continued expansion of its transmission network and the
switching facilities located in Los Angeles, New York and London.

Other Income (Expense): Other expense, net, increased to $791,000 in the first
nine months of 1997 from $390,000 in the first nine months of 1996. This
increase results from $1.2 million in interest expense incurred in 1997 under
the Company's bank line of credit as well as long term financing for switches,
undersea cable and other equipment. This expense was offset by $359,000 in
interest income and a $48,000 gain on the sale of short-term investments.

Provision for Income Taxes: The Company's provision for income taxes increased
to $2.4 million in the first nine months of 1997 from $1.2 million in the first
nine months of 1996. The effective tax rate decreased to 37.6% in the first nine
months of 1997 from 40.4% in the year prior reflecting the write-off of customer
account receivables as well as an increase in net deferred tax assets of $1.2
million.

LIQUIDITY AND CAPITAL RESOURCES

The Company generated $10.1 million in net cash from operating activities during
the first nine months of 1997 primarily through net income plus depreciation and
the provision for doubtful accounts. Increases in accrued network costs and
decreases in deposits largely offset increases in accounts receivable, prepaid
expenses and other assets. The Company's investing activities used cash of $25.1
million during the first nine months of 1997, primarily resulting from capital
expenditures and investing the net proceeds of the initial public offering in
marketable securities. The Company's financing activities provided net cash of
approximately $20.7 million which included the net proceeds from the initial
public offering of common stock of approximately $30.9 million offset by net
repayments under lines of credit, debt and capital lease obligations.

As of September 30, 1997, the Company had cash and cash equivalents of
approximately $7.4 million and short term investments of $20.9 million. Working
capital at the end of the third quarter was $22.2 million. The Company had
approximately $9.8 million outstanding for capital leases relating primarily to
the Company's switching equipment as of the current quarter end.

Through September 30, 1997, the Company used approximately $18.0 million of the
net proceeds from the initial public offering. Approximately $14.2 million was
used to repay indebtedness, $2.8 million was used to purchase switching and
transmission related equipment and $979,000 was used to finance the Company's
operations of the U.K. subsidiary. The Company anticipates making capital
expenditures of approximately $80.0 million over the next 18 months to expand
the Company's global network. The Company believes that the remaining proceeds
from the initial public offering, cash generated from operations, as well as
funding under its bank line of credit will satisfy a significant portion of the
Company's liquidity requirements. Effective as of September 30, 1997, the
Company executed an agreement with Sanwa Bank, California for a $25 million, 2
year revolving line of credit. As appropriate, the Company will use capital
lease financing or raise additional debt or equity capital to finance new
projects and or acquisitions. The Company intends to consummate the acquisition
of LD Services, a reseller of long distance telecommunications services, in the
fourth quarter of 1997. This acquisition will require working capital support
from the Company to finance expansion of its operations.
