     1.  PRINCIPLES OF CONSOLIDATION AND BASIS OF PRESENTATION


     The accompanying unaudited consolidated financial statements, which include
the accounts of ATSI-Delaware, ATSI-Canada, ATSI-Texas, ATSI-Mexico, ATSI de
CentroAmerica, Computel, Telespan, Sinfra, and GlobalSCAPE have been prepared in
accordance with Rule 10-01 of Regulation S-X, "Interim Financial Statements,"
and accordingly do not include all information and footnotes required under
generally accepted accounting principles for complete financial statements. In
the opinion of management, these interim financial statements contain all
adjustments, without audit, necessary to present fairly the consolidated
financial position of ATSI, Inc. and its subsidiaries ("ATSI" or "the Company")
as of July 31, 1999 and January 31, 2000, the results of their operations for
the three and six months ended January 31, 1999 and 2000 and cash flows for the
six months ended January 31, 1999 and 2000.  All adjustments are of a normal
recurring nature.  All significant intercompany balances and transactions have
been eliminated in consolidation.  It is recommended that these interim
consolidated financial statements be read in conjunction with the consolidated
financial statements and the notes thereto for the year ended July 31, 1999
included in our amended annual report on Form 10-K filed with the SEC on April
13, 2000 and August 25, 2000.  Certain prior period amounts have been
reclassified for comparative purposes. The results of operations for any interim
period are not necessarily indicative of the results to be expected for the full
year.

     In June 1998, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards (SFAS) No. 133, "Accounting for
Derivative Instruments and Hedging Activities". SFAS 133 establishes accounting
and reporting standards for derivative instruments, including certain derivative
instruments imbedded in other contracts, and for hedging activities.  It
requires that an entity recognize all derivatives as either assets or
liabilities in the statement of financial position and measure those instruments
at fair value. However, in June 1999, FASB issued Statement of Financial
Accounting Standards (SFAS) No. 137, "Accounting for Derivative Instruments and
Hedging Activities- Deferral of the Effective Date of FASB Statement No. 133".
SFAS 137 delays the effective date of SFAS 133 to June 15, 2000.  We believe the
adoption of this statement will not have a material effect on our financial
condition or results of operations.


     2.  FUTURE OPERATIONS

     Our consolidated financial statements have been prepared on the basis of
accounting principles applicable to a going concern.  For the period from
December 17, 1993 to January 31, 2000, we have incurred cumulative net losses of
approximately $27.8 million.   Further, we have a working capital deficit of
approximately $3.9 million at January 31, 2000.  Although we have capital
resources available to it, these resources are limited and may not be available
to support our ongoing operations until such time as we are able to maintain
positive cash flow from operations.  There is no assurance we will be able to
achieve future revenue levels sufficient to support operations or recover our
investment in property and equipment, goodwill and other intangible assets.
These matters raise substantial doubt

                                       7
<PAGE>

about our ability to continue as a going concern. Our ability to continue as a
going concern is dependent upon the ongoing support of our stockholders and
customers, our ability to obtain capital resources to support operations and our
ability to successfully market our services.

     We are likely to require additional financial resources in the near term
and could require additional financial resources in the long-term to support our
ongoing operations.  We have retained various financial advisers to assist us in
refining our strategic growth plan, defining our capital needs and obtaining the
funds required to meet those needs.  The plan includes securing funds through
equity offerings and entering into lease or long-term debt financing agreements
to raise capital.

     On February 17, 2000, we announced plans to capitalize on the value of our
wholly owned subsidiary, GlobalSCAPE, Inc. by spinning out a portion of our
ownership in GlobalSCAPE to our shareholders, and offering additional
GlobalSCAPE shares to ATSI shareholders and the GlobalSCAPE customer base.
Shareholders of ATSI will be allowed to participate in these transactions, which
are designed to accomplish three goals: 1) To increase ATSI shareholder value;
2) to raise funds necessary for further growth at GlobalSCAPE, and 3) to raise
funds necessary for further growth at ATSI. Management anticipates that the
transaction will provide cash to ATSI to reduce or eliminate our working capital
deficit. In addition, the transactions should also provide an ongoing benefit to
ATSI, as it will realize a stepped-up benefit through our retained ownership in
GlobalSCAPE, enhancing our own financial position and our ability to act on or
finance opportunities going forward.

     There can be no assurances, however, that such equity offerings or other
long-term debt financing arrangements will actually be consummated or that such
funds, if received, will be sufficient to support existing operations until
revenue levels are achieved sufficient to maintain positive cash flow from
operations.  If we are not successful in completing additional equity offerings
or entering into other financial arrangements, or if the funds raised in such
stock offerings or other financial arrangements are not adequate to support us
until a successful level of operations is attained, we have limited additional
sources of debt or equity capital and would likely be unable to continue
operating as a going concern.


     3. CAPITAL LEASES

     As of July 31, 1999, we entered into a capital lease transaction with NTFC
Capital Corporation, ("NTFC") to finance the purchase of a DMS 250/3000
International gateway switch from Northern Telecom, Inc. and additional
equipment totaling approximately $2,000,000 over a five and a half-year period
with payments delayed for six months. The lease facility requires that we meet
certain financial covenants on a quarterly basis beginning October 31, 1999,
including minimum revenue levels, gross margin levels, earnings before interest,
taxes and depreciation and amortization (EBITDA) results and debt to equity
ratios. As of October 31, 1999 and January 31, 2000, we were in default of
quarterly financial covenants related to revenues, gross margins and EBITDA. We
have received a waiver from NTFC stating that it waived our compliance
requirements as of those dates.  However, based upon our results before and
after the period ended January 31, 2000, we will most likely be in default of
these same covenants at the end of our next fiscal quarter, April 30, 2000.  As
such, we have requested that NTFC review our current business plan, including
expected results and capital requirements, in order to re-set the financial
covenants applicable to our capital lease obligation and prevent events of
default from occurring on a quarterly basis going forward.  Based on discussions
with NTFC, management believes it is probable that NTFC will re-set the
financial covenants such that we will be in compliance as of April 30, 2000.
NTFC is in the process of reviewing this information, and we anticipate
receiving the results of this review prior to April 30, 2000.  As such, we have
classified our obligation to NTFC as

                                       8
<PAGE>

long-term. However, should we not receive revised financial covenants from NTFC,
it is likely that we will be required to classify our entire obligation to NTFC
as current as of April 30, 2000.


     4.  NOTES PAYABLE

     In January 2000, the note holder converted a note payable into Common
Stock.  The note payable balance inclusive of principal, interest and other fees
was approximately $439,000. At issuance, the note payable had 250,000 warrants
to the note holder at an exercise price of $3.56 per share. Unamortized debt
discount associated with the warrants at the time of conversion was
approximately $87,000, which we fully expensed in January 2000.  The note
payable balance inclusive of principal, accrued interest and other fees was
converted into 370,603 shares of Common Stock.

     We utilize the services of a billing clearinghouse to process and collect
receivables related to our long distance call services. As part of a factoring
arrangement, the clearinghouse advances 75% of these receivables within five
days of presentment. Under a separate agreement with a financing company, we
were advanced an additional 13.75% of these receivables through April 1999. As
part of a tri-party agreement between us, the billing clearinghouse and the
financing company, the financing company was repaid by the billing clearinghouse
from payments arising from the ultimate collection of our long distance call
services receivables. In November 1999, we, under the tri-party agreement, paid
off the note payable to the financing company. The financing company now claims
that we owe an approximate $600,000. We believe that the amount claimed by the
financing company is in error and that the billing clearinghouse has, in fact,
paid the financing company approximately $160,000 more than what it is owed,
which we have reflected in the accompanying consolidated balance sheets as a
note receivable.  The billing clearinghouse has agreed not to transmit any
additional funds to the financing company until this dispute is resolved. We are
attempting to work with the financing company to resolve this dispute and obtain
a release of the funds held by the billing clearinghouse.

     Subsequent to the end of the quarter, we have been able to obtain a release
of funds held by the billing clearinghouse. Additionally, the financing company
has lowered the amount they claim we owe them to approximately $14,000. We still
believe that the financing company has been paid approximately $160,000 more
than what was owed and continue to resolve this dispute.


     5. CONVERTIBLE DEBT

     In January 2000, the note holders converted $2.2 million of convertible
notes, originally issued in March and May of 1997, which would have been due in
March 2000. The convertible notes' face value and accrued interest at the time
of conversion was approximately $2.2 million and $700,000, respectively. At
issuance, the convertible notes had 4,776,176 warrants to the convertible debt
holders at an exercise price of $0.27 per share. Unamortized debt discount
associated with the warrants at the time of conversion was approximately
$106,000, which we fully expensed in January 2000. In January 2000, conversion
of the notes resulted in the issuance of 726,257 shares of Common Stock related
to the warrants, 716,424 of which were the aforementioned $0.27 warrants and
9,833 of unrelated $0.85 warrants against the face value and accrued interest
owed them. The remaining convertible notes and accrued interest were converted
into 2,262,329 shares of Common Stock.

                                       9

     6.  PREFERRED STOCK

     In December 1999, we issued 1,425 shares of Series A Preferred Stock for
cash proceeds of approximately $1.4 million.  The Series A Preferred Stock
accrues cumulative dividends at the rate of 10% per annum.


     The Series A Preferred Stock and any accumulated, unpaid dividends may be
converted into Common Stock for up to one year at the average closing price of
the Common Stock for twenty (20) days preceding the Date of Closing (the
"Initial Conversion Price").  On each Anniversary Date up to and including the
fifth Anniversary Date, the Conversion price on any unconverted Preferred Stock,
will be reset to be equal to 75% of the average closing price of the stock for
the then twenty (20) preceding days provided that the Conversion price can not
be reset any lower than 75% of the Initial Conversion Price.  As this conversion
feature is considered a "a beneficial conversion feature" to the holder, we have
allocated approximately $603,000 of the approximate $1.4 million in proceeds to
additional paid-in capital as a discount to be amortized over a period of one
year. An additional approximate $380,000 of discount, which represents the
difference between the Initial Conversion Price and the market price on the
Commitment Date, will be amortized over a shorter ninety day period as this
represents the initial beneficial conversion feature realizable by the investor
after ninety days. The Company adjusted its preferred dividend expense to
$791,000 and $2.0 million for the three and six months ended January 31, 2000
from $634,000 and $1.9 million in its previously filed 2nd Quarter 10-Q. The
Series A Preferred Stock is callable and redeemable by us at 100% of its face
value, plus any accumulated, unpaid dividends at our option any time after our
Common Stock has traded at 200% or more of the conversion price in effect for at
least twenty (20) consecutive trading days, so long as we does not call the
Preferred Stock prior to the first anniversary date of the Date of Closing. The
terms of our Series A Preferred Stock restrict us from declaring and paying
dividends on our common stock until such time as all outstanding dividends have
been fulfilled related to the Preferred Stock.

     During the quarter, the holder of our Series B Preferred Stock elected to
convert the remaining 1,925 shares into our Common Stock. This conversion
resulted in the issuance of approximately 2,525,308 shares of our Common Stock
during the quarter. An additional 75 shares of Series B Preferred Stock had
previously been converted during the quarter ending October 31, 1999 resulting
in the issuance of approximately 99,906 shares of Common Stock.


     7. SEGMENT REPORTING

  In an attempt to identify our reportable operating segments, we considered a
number of factors or criteria. These criteria included segmenting based upon
geographic boundaries only, segmenting based on the products and services
provided, segmenting based on legal entity and segmenting by business focus.
Based on these criteria or factors we have determined that it has three
reportable operating segments: (1) U.S. Telco; (2) Mexico Telco; and (3)
Internet e-commerce.  Clearly, our Internet e-commerce subsidiary, GlobalSCAPE,
Inc. and its operations can be differentiated from the telecommunication focus
of the rest of the Company. Additionally, we believe that our U.S. and Mexican
subsidiaries should be separate segments in spite of the fact that many of the
products are borderless. Both, the U.S. Telco and Mexican Telco segments include
revenues generated from Integrated Prepaid, Postpaid, and Private Network
Services. Our Carrier Services revenues, generated as a part of our U.S. Telco
segment, are the only revenues not currently generated by both the U.S. Telco
and Mexico Telco segments.  We have included the operations of ATSI-Canada,
ATSI-Delaware and all businesses falling below the reporting threshold in the
"Other" segment. The "Other" segment also includes intercompany eliminations. We
have used earnings before interest, taxes, depreciation and amortization
(EBITDA) in our segment reporting as it is the chief measure of profit or loss
used in

                                       10
<PAGE>

assessing the performance of each of our segments.

     8. LEGAL PROCEEDINGS

     On February 11, 2000, we filed a Petition and Application for TRO and
Temporary Injunctive Relief in district court in Bexar County, Texas (Cause
Number 2000CI02032) against the former manager of our Costa Rican operations,
Alejandro Filloy, a former private network customer, Simple Communications
Technologies, Inc. and two other defendants, Gammacom Communicaciones, S.A. and
American Teleport Services, Inc. We allege that Alejandro Filloy and Simple
Communications used ATSI's assets to establish a competing business under the
names Gammacom (a Costa Rican corporation) and American Teleport Services (a
Florida corporation). We have asserted claims for conversion, fraud, and
tortious interference with contractual relations and conspiracy. We have also
asked for payment of unpaid amounts due from Simple Communications Technologies,
Inc. under its agreement for private network services.

     In addition, we have filed a demand for payment against another former
private network customer for services used and services which continue to accrue
under the terms of agreement. The former customer has asserted that it did not
have a binding written contract and does not owe us for any service not used.

     We have outstanding receivables related to these private network customers
for both services used and services which continue to accrue under the terms of
the respective agreements. While we can not estimate the possible loss, if any
related to these receivables, there can be no assurance that the resolutions of
both of these disputes would not have a material effect on our results of
operations. As such, we have established a reserve for the amounts related to
services, which continue to accrue under the agreements.

     9. RELATED PARTY TRANSACTIONS

     In February 2000, our Board of Directors approved a plan to lend
approximately $1.4 million, at a market interest rate, in the aggregate to
certain key executive officers to allow them to exercise approximately 2,250,000
of their vested options. The executive officers who borrowed under the plan must
adhere to the following conditions: 1) they must contribute 10% in cash of the
amount borrowed; 2) the stock obtained with the exercises must be escrowed under
a twelve month standstill agreement or

                                       12
<PAGE>

until such time as the note is paid; and 3) any derivative equity obtained from
the stock's ownership must be escrowed for a six-month period.


     10. SUBSEQUENT EVENTS

     In February 2000, we issued 3,000 shares of Series D Preferred Stock for
cash proceeds of approximately $3,000,000. The Series D Preferred Stock accrues
cumulative dividends at the rate of 6% per annum.

     The Series D Preferred Stock and any accumulated, unpaid dividends may be
converted into Common Stock for up to two years at the lesser of a) the market
price on the day prior to closing or b) 83% of the five lowest closing bid
prices on the ten days preceding conversion. As this conversion feature is
considered a "beneficial conversion feature" to the holder, we will allocate a
portion of the proceeds to additional paid-in capital as a discount to be
amortized over the lesser of the period most beneficial to the holder or upon
exercise of the conversion feature. The terms of our Series D Preferred Stock
restrict us from declaring and paying dividends on our common stock until such
time as all outstanding dividends have been fulfilled related to the Preferred
Stock.

     In February 2000, we issued 1,000 shares of Series A Preferred Stock for
cash proceeds of approximately $1.0 million. The Series A Preferred Stock
accrues cumulative dividends at the rate of 10% per annum.

     The Series A Preferred Stock and any accumulated, unpaid dividends may be
converted into Common Stock for up to one year at the average closing price of
the Common Stock for twenty (20) days preceding the Date of Closing (the
"Initial Conversion Price"). On each Anniversary Date up to and including the
fifth Anniversary Date, the Conversion price on any unconverted Preferred Stock,
will be reset to be equal to 75% of the average closing price of the stock for
the then twenty (20) preceding days provided that the Conversion price can not
be reset any lower than 75% of the Initial Conversion Price. The initial
beneficial conversion feature which represents the difference between the
Initial Conversion Price and the market price on the Commitment Date is
$1,000,000, therefore, we will allocate all of the proceeds to additional paid-
in capital as a discount to be amortized over a ninety day period the earliest
period at which the beneficial conversion feature could be realized. The Series
A Preferred Stock is callable and redeemable by us at 100% of its face value,
plus any accumulated, unpaid dividends at our option any time after our Common
Stock has traded at 200% or more of the conversion price in effect for at least
twenty (20) consecutive trading days, so long as we does not call the Preferred
Stock prior to the first anniversary date of the Date of Closing. The terms of
our Series A Preferred Stock restrict us from declaring and paying dividends on
our common stock until such time as all outstanding dividends have been
fulfilled related to the Preferred Stock.

General

     Our mission is to employ leading-edge technologies for delivery of
exceptional telecommunication services to underserved Latino markets in the U.S.
and Latin America emphasizing convenience, accessibility, quality, reliability,
and affordability, while continually seeking to add value through new and
innovative products and services. Utilizing a framework of licenses,
interconnection and service agreements, network facilities and retail
distribution channels (hereinafter collectively referred to as the "framework"),
we are primarily focused on capturing market share in the international
telecommunications corridor between the United States and Mexico. Even with poor
phone-line penetration, our research indicates that Mexico may exchange more
international traffic with the U.S. than any other country in the world within
the next two years. As the regulatory environments allow, we plan to establish
framework in other Latin American countries as well. In addition to the U.S. and
Mexico, we currently own or have rights to use facilities in and have strategic
relationships with carriers in Costa Rica, El Salvador, and Guatemala.

     Utilizing the framework described above, we provide local, domestic long
distance and international calls from our own public telephones and
communication centers within Mexico. Consumers visiting a Company-owned
communication center or public telephone may dial directly to the desired party
in exchange for cash payment, or can charge the call to a U.S. address (collect,
person-to-person, etc.) or calling card, or to a U.S. dollar-denominated credit
card with the assistance of an operator. In July 1998, we began providing
domestic U.S. and international call services to Mexico to residential customers
on a limited basis in the U.S. Callers may either pre-subscribe to our one-plus
residential service, or dial around their pre-subscribed carrier by dialing 10-
10-624, plus the area code and desired number. Where possible, these retail
calls are transported over our own network infrastructure.

                                       14
<PAGE>

     Utilizing the same framework described above, we also serve as a retail and
wholesale facilities-based provider of network services for corporate clients
and U.S. and Latin American telecommunications carriers.  These customers
typically lack transmission facilities into certain markets, or require
additional capacity into certain markets. We currently provide these services to
and from the United States, Mexico, Costa Rica, El Salvador and Guatemala.

     We are also the sole owner of GlobalSCAPE, Inc., which is rapidly becoming
a leader in electronic commerce of top Internet-based software, utilizing the
Web as an integral component of its development, marketing, distribution and
customer relationship strategies.  Utilizing CuteFTP as its flagship product,
GlobalSCAPE has a user base of approximately 10 million users as of January 31,
2000.

     Our consolidated financial statements have been prepared assuming that we
will continue as a going concern. We have incurred losses since inception and
have a working capital deficit as of January 31, 2000.  For the reasons stated
in Liquidity and Capital Resources and subject to the risks referred to in
Liquidity and Capital, we expect improved results of operations and liquidity in
the rest of fiscal 2000.

</TABLE>

Three Months Ended January 31, 2000 Compared to Three Months Ended January 31,
1999

     Operating revenues. Operating revenues increased approximately $2.6
million, or 31%, due to increases in our carrier, integrated prepaid and
Internet e-commerce services. This increase was offset to some extent by the
decline in our private network and postpaid services.

     Network management services increased approximately $2.6 million, or 60%.
This growth was principally due to the additional minutes processed for other
carriers during the quarter ended January 31, 2000. We processed approximately
16.1 million minutes of traffic for other carriers during the quarter ended
January 31, 1999, as compared to approximately 44.0 million minutes during the
quarter ended January 31, 2000.  In the fourth quarter ended July 31, 1999, our
alternate fiber route became fully operational enabling us to increase our
volume of carrier traffic.  While the volume of carrier traffic will most likely
increase as compared to previous years, we may not be able to maintain this
growth trend as we continue to increase our focus on retail-based call services,
which tend to be less volatile than wholesale traffic. Our private network
revenues declined from $1.2 million to $602,000 between periods due to the loss
of customers upon expiration or termination of their contracts. We have shifted
our focus away from the provision of these private network services to public
traffic in the U.S.-Mexican corridor. For the three months ended January 31,
2000 approximately $125,000 of private network revenues were included in the
external revenues of our Mexico Telco segment as detailed in Note 7 in the
accompanying financial statements. All other network management services
revenues are included in the external revenues of our U.S. Telco segment.

     Call service revenues decreased approximately $698,000, or 22% between
quarters. The decline was principally attributable to lower volumes of operator-
assisted calls originating in Mexico and terminating in the U.S, new services
such as prepaid cellular being introduced into the market by our competitors,
and Mexican cellular providers recently introducing the concept of "calling
party pays". During the quarter ended January 31, 2000, we processed
approximately 14,000 operator-assisted calls originating in Mexico and
terminating in the U.S. as compared to approximately 42,000 calls processed in
the quarter ending January 31, 1999. We now provide these services almost
exclusively from our own communication centers and payphones, due to the added
expenses associated with third party owned locations. As we believe this call
volume trend may continue, we have has recently begun utilizing the services of
third-party owned operator centers to further reduce the cost of providing these
calls. Integrated prepaid services, calls processed in exchange for cash without
utilizing an operator center, increased to $1.5 million from $1.4 million for
the periods ended January 31, 2000 and January 31, 1999, respectively. The calls
are paid for almost exclusively in pesos, and the resulting revenues are
translated to U.S. dollars in the accompanying consolidated financial
statements. The average conversion rate of pesos to dollars during the quarters
ended January 31, 1999 and January 31, 2000, was 10.0 and 9.4 respectively.
While call volumes increased slightly between periods, the pesos generated
converted to more U.S. dollars, period to period. Revenues from our integrated
prepaid services are all recorded in the external revenues of our Mexico Telco
segment. With the exception of approximately $196,000 of postpaid revenues
included in our Mexico Telco operations all of our postpaid revenues are
included in our U.S. Telco operations. Further segment information can be found

                                       16
<PAGE>

in Note 7 of our accompanying financial statements.

     Our Internet e-commerce services increased approximately $660,000, or 106%
between quarters. This growth was due primarily to the increased number of
downloads of our CuteFTP product between quarters. Downloads grew from nearly
605,000 in the quarter ended January 1999 to nearly 2.32 million in the quarter
ended January 2000.  The increase in downloads has resulted in a corresponding
increase in our revenues as downloads serve as the primary driver of revenues in
coming months as well as increasing the target audience for banner
advertisements. We began selling banner advertisements in April 1999 and
advertising revenues produced approximately 18% of overall e-commerce revenues
during the quarter ended January 31, 2000.


     Cost of Services.  Cost of services increased approximately $2.3 million,
or 47%, between quarters and increased as a percentage of revenues from 59% to
67%, between quarters.  The increase in cost of services was principally
attributable to the increased volume of business handled by us as discussed
above. As discussed in revenues most of this increase was related to our carrier
services product, which is accounted for in our U.S. Telco segment. The increase
in cost of sales, as a percentage of revenues, was due primarily to the
percentage of lower margin carrier services traffic increasing from 38% to 59%
of overall corporate revenues, quarter to quarter. The resultant change in our
traffic mix led to an increase in the combined telco operations cost of services
from 65% to 75% for the quarter.

     Selling, General and Administrative (SG&A) Expense. SG&A expenses increased
6%, or approximately $175,000, between quarters. As a percentage of revenues,
these expenses decreased from 38% to 30% between quarters. This increase in SG&A
was primarily due to added SG&A costs at our Internet e-commerce subsidiary to
support the introduction of new products into the market. SG&A costs associated
with our telco businesses remained relatively flat between periods due to cost
reduction efforts and in spite of expenses incurred with the completion of our
plan to consolidate our Mexico City and Guadalajara operations into one office
in Mexico City. The decrease in SG&A, as a percentage of revenues, was
principally attributable to the increased volume of carrier services business
generated by us during the quarter ended January 31, 2000, which generated
significantly lower overhead costs relative to other services provided by us.

     Depreciation and Amortization. Depreciation and amortization rose
approximately $669,000, or 88%, between quarters and increased as a percentage
of revenues from 9% to 13%. The increase was primarily related to purchases of
property, plant and equipment of approximately $1.4 million between January 31,
1999 and January 31, 2000 and the purchase of the rights to the source code of
CuteFTP in January 1999. We also began providing additional depreciation expense
as a result of a change in accounting estimate for useful lives within our
Mexican subsidiaries. We also fully depreciated approximately $165,000 of our
fixed assets for which we believe there are no associated future benefits.

     Operating Loss. Our operating loss increased approximately $499,000
between quarters and increased as a percentage of revenues from 8% to 11%, due
to higher cost of services and selling, general and administrative expenses as a
percentage of revenues, and increased depreciation and amortization.

     Other Income (Expense). Other income (expense) increased approximately
$224,000 between quarters. This increase was principally attributable to
additional debt discount expense associated with our conversion of convertible
notes and a note payable during the quarter. Other increases in interest expense
are a result of increased indebtedness and capital leases.

                                       17
<PAGE>

     Preferred Dividends. During the second quarter of fiscal 2000, we recorded
approximately $791,000 of non-cash dividends related to cumulative convertible
preferred stock. In addition to cumulative dividends on our Series A, Series B
and Series C Preferred Stock, which are accrued at 10%, 6% and 6%, respectively,
per month we have recorded amortization related to a discount or "beneficial
conversion feature" associated with the issuance of our various preferred stock
issuances.  Our preferred stock issuances issued between March 1999 and December
1999 were approximately $6.3 million.

     Net loss. The net loss between quarters increased by approximately $1.5
million from $1.1 million to $2.6 million due primarily to increased
depreciation and amortization, increased interest expense and preferred stock
dividends.

Six Months Ended January 31, 2000 Compared to Six Months Ended January 31, 1999

     Operating revenues. Operating revenues increased approximately $1.8
million, or 10%, due to growth in our carrier, integrated prepaid and Internet
e-commerce services. This increase was offset to some extent by the decline in
our private network and postpaid services.

     Network management services increased approximately $2.0 million, or 18%.
This growth was principally due to the additional minutes processed for other
carriers during the quarter ended January 31, 2000. We processed approximately
43.0 million minutes of traffic for other carriers during the six months ended
January 31, 1999, as compared to approximately 87.0 million minutes during the
six months ended January 31, 2000. While the volume of carrier traffic will most
likely increase as compared to previous years, we may not be able to maintain
this growth trend as we continues to increase our focus on retail-based call
services, which tend to be less volatile than wholesale traffic. Our private
network revenues declined from $2.3 million to $1.3 between periods due to the
loss of customers upon expiration or termination of their contracts. We have
shifted our focus away from the provision of these private network services to
public traffic in the U.S.-Mexican corridor. With the exception of approximately
$274,000 of private network revenues included in external revenues for our
Mexico Telco segment all of our network management services revenues are
included in our U.S. Telco segment.

     Call service revenues decreased approximately $1.1 million, or 18% between
periods.  The decline was principally attributable to lower volumes of operator-
assisted calls originating in Mexico and terminating in the U.S, new services
such as prepaid cellular being introduced into the market by our competitors,
and Mexican cellular providers recently introducing the concept of "calling
party pays".  During the six months ended January 31, 2000, we processed
approximately 32,000 operator-assisted calls originating in Mexico and
terminating in the U.S. as compared to approximately 83,000 calls processed in
the six months ending January 31, 1999.  We now provide these services almost
exclusively from our own communication centers and payphones, due to the added
expenses associated with third party owned locations. As we believe this call
volume trend may continue, we have recently begun utilizing the services of
third-party owned operator centers to further reduce the cost of providing these
calls. Integrated prepaid services, calls processed in exchange for cash without
utilizing an operator center, increased to $2.9 million from $2.6 million for
the periods ended January 31, 2000 and January 31, 1999, respectively. The calls
are paid for almost exclusively in pesos, and the resulting revenues are
translated to U.S. dollars in the accompanying consolidated financial
statements.  The average conversion rate of pesos to dollars during the periods
ended January 31, 1999 and January 31, 2000, was 10.0 and 9.4 respectively.
While call volumes increased slightly between periods, the pesos generated

                                       18
<PAGE>

converted to more U.S. dollars, period to period.  Approximately $1.9 million of
our postpaid revenues are included in U.S. Telco external revenues with the
remaining $307,000 included in our Mexico Telco external revenues. For the six
months ended January 31, 2000 all of our integrated prepaid services have been
included in the external revenues of our Mexico Telco segment.

     Our Internet e-commerce services increased approximately $877,000, or 75%
between periods. This growth was due primarily to the increased number of
downloads of our CuteFTP product between periods. Downloads grew from nearly 1.2
million in the six months ended January 31, 1999 to approximately 4.3 million in
the six months ended January 31, 2000.  The increase in downloads has resulted
in a corresponding increase in our revenues as downloads serve as the primary
driver of revenues in coming months as well as increasing the target audience
for banner advertisements.

     Cost of Services. Cost of services increased approximately $2.3 million,
or 20%, between periods and increased as a percentage of revenues from 62% to
68%, between periods. The increase in cost of services was principally
attributable to the increased volume of business handled by us as discussed
above. As discussed in revenues most of this increase was related to our carrier
services product, which is accounted for in our U.S. Telco segment. The increase
in cost of sales, as a percentage of revenues, was due primarily to the
percentage of lower margin carrier services traffic increasing from 48% to 58%
of overall corporate revenues, period to period. The resultant change in our
traffic mix led to an increase in the combined telco operations cost of services
from 65% to 75% for the period.

     Selling, General and Administrative (SG&A) Expense. SG&A expenses
increased 7%, or approximately $440,000, between periods. As a percentage of
revenues, these expenses remained relatively constant. The increase in SG&A was
primarily due to added SG&A costs at our Internet e-commerce subsidiary to
support the introduction of new products into the market. SG&A costs associated
with our telco businesses remained relatively flat between periods due to cost
reduction efforts and in spite of expenses incurred with the completion of our
plan to consolidate our Mexico City and Guadalajara operations into one office
in Mexico City.

     Depreciation and Amortization. Depreciation and amortization rose
approximately $928,000, or 66%, between periods and increased as a percentage of
revenues from 7% to 11%.  The increase was primarily related to purchases of
property, plant and equipment of approximately $1.4 million between January 31,
1999 and January 31, 2000 and the purchase of the rights to the source code of
CuteFTP in January 1999, We also began providing additional depreciation expense
as a result of a change in accounting estimate for useful lives within our
Mexican subsidiaries. Additionally, we fully depreciated approximately $165,000
of our fixed assets for which we believe there are no associated future
benefits.

     Operating Loss. Our operating loss increased approximately $1.7 million
between periods and increased as a percentage of revenues from 5% to 13%, due to
higher cost of services and increased depreciation and amortization.

     Other Income (Expense).  Other income (expense) increased approximately
$201,000 between periods. This increase was principally attributable to
additional debt discount expense associated with our conversion of convertible
notes and a note payable in January 2000. Additional increases in interest
expense are a result of increased indebtedness and capital leases.

     Preferred Dividends. During the six months ending January 31, 2000, we
recorded approximately $2.1 million of non-cash dividends related to cumulative
convertible preferred stock. In

                                       19
<PAGE>

addition to cumulative dividends on our Series A, Series B and Series C
Preferred Stock, which are accrued at 10%, 6% and 6%, respectively, per month we
have recorded amortization related to a discount or "beneficial conversion
feature" associated with the issuance of our various preferred stock issuances.
The proceeds of the preferred stock issuances were approximately $6.3 million.

     Net loss. The net loss for the six months ended January 31, 2000 increased
approximately $4.1 million to $5.8 million from the $1.7 million net loss for
the six months ended January 31, 1999. The increased net loss was due primarily
to increased selling, general and administrative expenses, increased
depreciation and amortization expense, increased interest expense and the
preferred stock dividends.

Liquidity and Capital Resources

     During the six-month period ended January 31, 2000, we generated negative
cash flows from operations of $515,000.  The amount of cash used in our
operations is a result of the net loss incurred during the period, as well as
activities related to payments to vendors.  We have historically operated with
negative cash flows and negative working capital, and have sought to fund those
losses and deficits by completing private equity placements.

     For the six-month period ended January 31, 2000, our net loss, after
adjustments for non-cash items (depreciation and amortization, amortization of
debt discount, deferred compensation and the provision for losses on accounts
receivable) was approximately $575,000.  Management of the operating assets and
liabilities, which consists mainly of collections on accounts receivable and
payments made on outstanding payables, produced positive cash flows of
approximately $60,000, resulting in the negative cash flows for the period of
$515,000. As noted in Notes 4 and 8 of our accompanying financial statements we
have disputed receivables which have affected our cash flows. We continue to
pursue the amounts due from the financing company as noted in Note 4 as well as
our two former customers as noted in Note 8. Should we not be able to resolve
these disputes in our favor it will require cash outflows of approximately
$14,000 as well as a reduction in expected cash inflows.

     For the three-month period ended January 31, 2000, we produced positive
income, after adjustments for the same non-cash items mentioned above, of
approximately $94,000.  However, management of our operating assets and
liabilities resulted in a net amount of cash being used of $1.1 million.  During
this period, our accounts receivable balance increased approximately $1.0
million due to increased business.  Although the increased business translated
to increased expenses during the period, we reduced our payables balance by
approximately $476,000 utilizing cash produced by private equity issuances.
Primarily as a result of these activities, we used approximately $959,000 in
cash in our operating activities during the three months ended January 31, 2000.

     Until we are able to produce positive cash flows from operations on a
recurring basis, and reduce or eliminate our working capital deficit, management
will be faced with deciding whether to use available funds to pay vendors and
suppliers for services necessary for operations, to service our debt
requirements, or to purchase equipment to be used in the growth of our business.
Should our available funds not be sufficient to pay vendors and suppliers, to
service debt requirements and purchase equipment we will need to continue to
raise additional capital. Until then, our operating activities may result in net
cash being used, or provided, during quarterly periods, regardless of our income
statement results for the periods. As noted in our amended Form 10-K we have not
always paid all of our suppliers on time. Some of these suppliers are critical
to our operations. These suppliers have given us payment extensions in the past,
although there is no guarantee they will do so in the future.

                                       20
<PAGE>

     During the six month period ended January 31, 2000, we received net cash
proceeds of $1.8 million from the issuance of preferred stock, and $920,000 from
the issuance of common stock as a result of warrant and option exercises.
These funds were used to pay down outstanding payables balances as mentioned
above, to make payments on our debt and capital lease obligations, and to
purchase approximately $688,000 in equipment used in our network operations.
The net result of our operating, investing and financing activities was an
increase in cash during the period of $284,000, and a working capital deficit as
of January 31, 2000 of approximately $3.9 million.  This represents a $3.0
million improvement over our working capital deficit of $6.9 million as of July
31, 1999 and a $6.4 million improvement over the working capital deficit of
$10.3 million as of October 31, 1999.

     Although we produced positive net cash flows during the six month period
ending January 31, 2000, the improvement in working capital was primarily due to
the conversion of approximately $2.9 million in outstanding notes and accrued
interest into our common stock which had been scheduled to mature in March 2000.
The notes as issued provided that ATSI could issue a series of redeemable
preferred stock and convert the notes to the preferred stock prior to maturity.
By means of letters sent December 30, 1999 and January 24, 2000 we offered to
allow the note holders to exercise outstanding warrants by offsetting the
exercise price against amounts accrued on their outstanding notes and the right
to convert any remaining balance of the notes to common stock at a discount of
20% to the average closing price of our common stock during the month of
January. The amount of the discount was consistent with the other preferred
stock deals we completed just prior to and subsequent to January 31. Note
holders having accrued balances of approximately $2.27 million accepted our
offer. The additional note holders were paid in full from the proceeds of a
private placement with the same terms as the conversion. As of January 31, 2000,
we have also classified approximately $1.9 of our capital lease obligation to
NTFC Capital Corporation ("NTFC") as long-term.  This obligation was classified
as a current liability as of October 31, 1999.  Although we were in default of
financial covenants related to revenues, gross margins and EBITDA, we received a
waiver from NTFC stating that it waived our compliance requirements as of those
dates.  Based upon our results before and after the period ended January 31,
2000, we will most likely be in default of these same covenants at the end of
our next fiscal quarter, April 30, 2000.  As such, we have requested that NTFC
review our current business plan, including expected results and capital
requirements, in order to re-set the financial covenants applicable to our
capital lease obligation and prevent events of default from occurring on a
quarterly basis going forward.  Based on discussions with NTFC, management
believes it is probable that NTFC will re-set the financial covenants such that
we will be in compliance as of April 30, 2000.  NTFC is in the process of
reviewing this information, and we anticipate receiving the results of this
review prior to April 30, 2000.  As such, we have classified our obligation to
NTFC as long-term.  However, should we not receive revised financial covenants
from NTFC, it is likely that we will be required to classify our entire
obligation to NTFC as current as of April 30, 2000.

     Our current liabilities as of January 31, 2000 are approximately $10
million. Included in our current obligations are $1.5 million of current capital
leases, approximately $340,000 of current note payables and approximately $8
million of accounts payable and accrued liabilities Until we are able to produce
positive cash flows from operations on a recurring basis, we will need to
continue to seek outside sources of funds to continue operations on a long-term
basis.  Subsequent to January 31, 2000, we have raised an additional $4,000,000
in private placements of preferred stock; $3,000,000 of 6% Series D Preferred
Stock and an additional $1,000,000 of 10% Series A Preferred Stock. The material
terms of these various preferred stock issuances can be found in Note 10 of this
amended 10-Q.

                                       21

     As discussed in Note 9 of the accompanying financial statements, our Board
of Directors approved a plan to lend approximately $1.4 million, at a market
interest rate, to certain key executive officers to allow them to exercise
approximately 2,250,000 of their vested options.  Most of these options were
granted under our 1997 stock option plan as non-qualified options. In order to
meet the exercise price and tax obligations it is likely that an exercise of
options by these key executive officers would have required them to sell some of
their shares immediately upon exercise. The Board believed it to be the best
interest of our shareholders not to have these key executive officers sell their
shares at a time when we were seeking a primary exchange listing.

     On February 17, 2000, we announced plans to capitalize on the value of our
wholly owned subsidiary, GlobalSCAPE, Inc. by spinning out a portion of our
ownership in GlobalSCAPE to our shareholders, and offering additional
GlobalSCAPE shares to ATSI shareholders and the GlobalSCAPE customer base.
Shareholders of ATSI will be allowed to participate in these transactions, which
are designed to accomplish three goals: 1) To increase ATSI shareholder value;
2) to raise funds necessary for further growth at GlobalSCAPE, and 3) to raise
funds necessary for further growth at ATSI. Management anticipates that the
transaction will provide cash to ATSI to reduce or eliminate our working capital
deficit. In addition, the transactions should also provide an ongoing benefit to
ATSI, as it will realize a stepped-up benefit through our retained ownership in
GlobalSCAPE, enhancing our own financial position and our ability to act on or
finance opportunities going forward. However, depending on the percentage of our
ownership to be retained after the spin-off and offering, GlobalSCAPE will
contribute less profits and cash flows to ATSI.  Because GlobalSCAPE currently
contributes significantly to our consolidated EBITDA results, we expect our
consolidated operating and cash flow results to decline after the spin-off and
offering.


     On July 28, 2000 we filed an amended Form 10 for our wholly-owned
subsidiary GlobalSCAPE, Inc. in which we noted that in light of current market
conditions we have decided not to make a public offering of GlobalSCAPE common
stock contemporaneously with the distribution. We will complete the distribution
as planned and we will continue to evaluate a public offering as well as other
alternatives to finance GlobalSCAPE's growth and raise funds for ATSI. The
distribution is expected to occur on or before September 8, 2000 to shareholders
of record as of July 14, 2000.

     In the near term, we must continue to manage our costs of providing
services and overhead costs as we begin focusing on optimizing use of our
network. We have applied for a long distance concession in Mexico which, if
obtained, we believe will eventually allow us to significantly reduce our cost
of transporting services. In order for us to significantly reduce costs with the
concession, we would need to purchase a significant amount of hardware and
software, allowing us to expand and operate our own network in Mexico. We
believe that these capital expenditures may approximate $60 million over a five-
year period. Should we be granted this concession we would likely need to raise
these funds through additional debt and/or equity capital. While we believe that
we would be able to raise these funds upon the granting of a concession, we can
give no assurance that we will be able to do so.

     Until we are able to produce positive cash flows from operations in an
amount sufficient to meet our debt service and capital expenditure requirements,
we must be able to access debt and/or equity capital to assist us in doing so,
although no assurance may be given that we will be able to do so. In an effort
to meet our financial needs going forward, we have engaged the investment
banking firm of Gerard, Klauer Mattison & Co. ("GKM"). GKM will assist us in
finding and securing financial and strategic relationships. While we will
continue to work with GKM in forming medium and long-term financing solutions,
it may be necessary for us to continue to access debt and/or equity capital in
the near-term.

Inflation/Foreign Currency

     Inflation has not had a significant impact on our operations.  With the
exception of integrated prepaid revenues from our communication centers and
payphones, almost all of our revenues are generated and collected in U.S.
dollars. Integrated prepaid services from our communication centers and
payphones are provided at the time of the call in exchange for cash payment, so
we do not maintain receivables on our books that are denominated in pesos. In an
effort to reduce foreign currency risk, we attempt to convert pesos collected to
U.S. dollars quickly and attempt to maintain minimal cash balances denominated
in pesos. Some expenses related to certain services provided by us are incurred
in foreign currencies, primarily Mexican pesos. The devaluation of the Mexican
peso over the past several years has not had a material adverse effect on our
financial condition or operating results.

Market Risk

     We are subject to several market risks. Specifically, we face commodity
price risks, equity price risks and foreign currency exchange risk.

     Certain of our businesses, namely wholesale carrier services, operate in an
extremely price sensitive environment. The wholesale business over the past
twelve months has seen significant reductions in the price per minute charged
for transporting minutes of traffic. While we have been able to withstand these
pricing pressures, certain of our competitors are much larger and greater
positioned to continue to withstand these price reductions. Our ability to
further absorb these price reductions may be dependent on our ability to further
reduce our costs of transporting these minutes.

     Until such time as we are able to consistently produce positive cash flows
from operations it will be dependent on our ability to continue to access debt
and equity sources of capital.  While recent history has shown us capable of
raising equity sources of capital; future equity financings and the terms of
those financings will be largely dependent on our stock price, our operations
and the future dilution to our shareholders.

     We face two distinct risks related to foreign currency exchange risk;
transaction risk and translation risk.

     As previously discussed under the caption "Inflation", We face risks
related to certain of our revenue streams, namely, direct dial or integrated
prepaid services from our own Mexican communication centers and payphones and
the transacting of business in pesos as opposed to U.S. dollars. Historically,
we have been able to minimize foreign currency exchange risk by converting from
pesos to U.S. dollars quickly and by maintaining minimal cash balances
denominated in pesos.  As we grows our retail business in Mexico it is likely
that we will face increasing foreign currency transaction risks.

     Historically, we have recorded foreign currency translation gains/losses
due to the volatility of the peso exchange rate as compared to the U.S. dollar
over time. We anticipate we will continue to experience translation gains/losses
in our assets and liabilities, specifically in fixed assets which are accounted
for at historical pesos amounts on the books of our Mexican subsidiaries but
converted to U.S. dollars for consolidation purposes at current exchange rates.

PART II OTHER INFORMATION

Item 2 Change in Securities and Use of Proceeds

     Our registration statement on form S-3, File No. 333-84115, on which we
registered 3,198,054 shares of common stock, became effective on August 19,
1999.  This common stock was issuable under the terms of our 6% Series B
Cumulative Convertible Preferred Stock and a warrant for the purchase of 50,000
shares of common stock both issued to The Shaar Fund on July 2, 1999 and under
the terms of two warrants for the purchase of common stock issued to Gary Wright
and Rocky Dazzo each on November 6, 1998.

     The warrants held by Gary Wright and Rocky Dazzo expired before they were
exercised.

     The Shaar Fund converted all of its series B preferred stock into common
stock between October 5, 1999 and January 24, 2000 resulting in the issuance of
2,541,734 shares of common stock.  We also issued The Shaar Fund 29,368 shares
and 12,372 shares, respectively of common stock in payment of dividends due on
the series B preferred stock on September 29, 1999 and December 31, 1999,
respectively.  The Shaar Fund exercised its warrant for 50,000 shares of common
stock on February 10, 2000.  The Shaar Fund has informed us that it has sold all
of the shares of common stock resulting from the conversion of the series B
preferred stock, the issuance of dividends on the series B preferred stock, and
the exercise of the warrant.

We did not receive any of the proceeds of the sale of the common stock
registered on this Form S-3.  We received $2,000,000 of proceeds upon the
issuance of the series B preferred stock on July 2, 1999.  We incurred expenses
in connection with the issuance of the series B preferred stock and registration
of the underlying common stock as follows (approximate amounts):

<TABLE>
                     <S>                          <C>
                     Legal fees:                  $ 50,000.00
                     Registration fees:             11,677.55
                     Printing & Miscellaneous:       5,000.00
                     Placement Fee:                200,000.00 (plus warrant described below)
                     ----------------------------------------
                     Total:                        266,677.55
</TABLE>

     Our placement fee to Corporate Capital Management LLC for services in
connection with the series B preferred stock consisted of the $200,000 cash
listed above and a warrant for the purchase of 50,000 shares of our common stock
at an exercise price of $1.25 per share.  None of these expenses were paid
directly or indirectly to any officer or director or affiliate of us, or any
person owning ten (10) percent or more of our common stock, or any of their
associates.

     We used the $1,734,000 remaining after payment of expenses for working
capital purposes. Of this amount, $14,855.71 was paid to two companies
controlled by our director, Tomas Revesz as fees due under service agreements.
No other proceeds were paid directly or indirectly to any officer or director or
affiliate of us, or any person owning ten (10) percent or more of our common
stock, or any of their associates.

     In September 1999 we issued 500 shares of Series C preferred stock for
approximately $500,000

                                       24
<PAGE>


and a warrant to purchase 20,000 shares of common stock at $1.19. Additionally,
we will issue 19,693 shares of common stock to Corporate Capital Management LLC
for introducing us to the Shaar Fund. As noted in Note 8 of our amended 10-K our
Series C preferred stock converts to common stock at a discount to market based
on the lower of an Initial Conversion Price or 78% of the five lowest closing
bid prices of the ten days preceding conversion. The Series C preferred stock
accrues dividends at 6% per annum. The Shaar Fund converted all of its Series C
preferred stock in March 2000 for approximately 485,000 shares of our common
stock. We currently have a pending Registration statement on Form S-3 (File No.
333-89683) to register these shares.

     In November 1999 we issued 31,566 shares of common stock with a market
value of $25,000 in accordance with an outstanding agreement with Dr. James
McCourt, Jr., an individual shareholder whereby he will guarantee up to $500,000
of our capital lease debt.

     In December 1999 we issued in two separate transactions 4,255 shares and
10,000 shares of our Series A preferred stock for cash proceeds of approximately
$425,500 and $1,000,000, respectively. Additionally, we issued 115 shares for
services rendered in connection with the placement of the 4,255 shares and
106,045 warrants to purchase common stock at $.9430 for services rendered in
connection with the placement of the 10,000 shares. As noted in Note 6 of this
amended 10-Q our Series A preferred stock converts to common stock at a discount
to market originally defined as the Initial Conversion Price. This conversion
price is reset on each anniversary date to the lower of 75% of the then
calculated conversion price or 75% of the initial conversion price so long as
the conversion price can never be reset any lower than 75% of the initial
conversion price. The Series A preferred stock accrues dividends at 10% per
annum.

     In January 2000 we issued approximately 2,632,929 shares of our common
stock to holders of convertible notes originally issued in March 1997 and the
holder of a note payable originally issued in October 1997. The shares were
issued in consideration of approximately $3.3 million of debt owed to the
holders. Certain holders exercised warrants they held against the amounts due
them reducing the amount of shares issued to them related to the conversion of
debt. The debt for all holders was converted at an exercise price of $1.1844 the
average closing price for the month of January 2000 except for holders of
approximately $632,202 of debt who elected to be paid in cash. The cash was
raised through a private placement at identical terms to the conversion of the
other holders debt resulting in the issuance of  533,774 shares of our common
stock, which is included in the 2,632,929 shares.  The Company further issued
118,800 shares of common stock to a company for services rendered in connection
with the debt conversion and refinancing. We currently have a pending
Registration Statement on Form S-3 (File No. 333-35846) to register these
shares.

     The terms of our Series A, B, and C preferred stock restrict us from
declaring and paying dividends on our common stock until such time as all
dividends have been fulfilled related to our preferred stock.

     Each of these offerings were transactions by an issuer not involving any
public offering under Section 4(2) of the Securities Act of 1933, as amended and
SEC Regulation D.
