                     NOTES TO CONDENSED FINANCIAL STATEMENTS
                                   (Unaudited)

1.     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 Article
       10 of Regulation S-X of the Securities and Exchange Commission. The
       accompanying unaudited condensed financial statements reflect, in the
       opinion of management, all adjustments necessary to achieve a fair
       statement of the Company's financial position and results for the interim
       periods presented. All such adjustments are of a normal and recurring
       nature. These condensed financial statements should be read in
       conjunction with the financial statements and notes thereto included in
       the Company's Registration Statement on Form SB-2 (File No. 333-59527)
       relating to the Company's initial public offering, which was declared
       effective by the Securities and Exchange Commission on December 9, 1998.

2.     Internet America, Inc. (the "Company") completed an initial public
       offering of its common stock in December 1998 (the "Offering"). The
       Company sold 1,700,000 shares and selling shareholders sold 600,000
       shares of common stock at a price of $13 per share. Proceeds from the
       Offering, net of underwriting discounts and offering expenses, were
       $19.8 million. Part of these proceeds were used to pay certain 
       indebtedness of $2.1 million. On January 4, 1999, the Company's lead
       underwriter exercised its overallotment option and purchased an 
       additional 345,000 shares of common stock from the selling shareholders
       at $13 per share.

       Immediately after the Offering, each outstanding share of Series A and
       Series B convertible preferred stock was converted into 2.25 shares of
       common stock and a warrant to purchase 33,750 shares of common stock was
       exercised.

3.     There are no adjustments required to be made to net income (loss) for the
       purpose of computing basic and diluted earnings per share ("EPS"). A
       reconciliation of the weighted-average number of common shares
       outstanding used in the basic and diluted EPS computation is as follows:

</TABLE>

       During the quarter ended December 31, 1998, the following instruments
       were not included in the computation of diluted EPS because the Company
       incurred a net loss for the period and the effect of such instruments is 
       antidilutive: (i) options to purchase 1,208,099 shares of common stock, 
       (ii) 1,020,002 shares of convertible preferred stock and (iii) a warrant 
       to purchase 33,750 shares of common stock. As of December 31, 1998, no 
       options to purchase shares of common stock had been exercised.

4.     On January 12, 1999, the Company filed a Registration Statement on Form
       S-8 (File No. 333-70461 ) to register 225,000 shares of Common Stock
       associated with the Company's 1996 Incentive Stock Option Plan. On
       February 10, 1999, the Company filed a Registration Statement on Form S-8
       (File No. 333-72109) to register 495,000 shares of common stock
       associated with certain non-qualified stock option agreements.
       Additionally, on February 10, 1999, the Company filed a Registration
       Statement on Form S-8 (File No. 333-72111) to register 235,000 shares of
       common stock associated with certain stock option settlement agreements.

5.     On January 29, 1999, the Company entered into an Asset Purchase Agreement
       with CompuNet, Inc., an Internet service provider located in Dallas,
       Texas. Under the terms of this agreement, Internet America, Inc. acquired
       CompuNet, Inc.'s customer base and all other assets for total
       consideration of approximately $2 million, which consisted of common
       stock of Internet America, Inc. and the assumption of certain
       liabilities. The transaction is expected to be accounted for as a
       pooling-of-interests. Accordingly, the financial statements included in
       all future filings will be restated to include the results of operations
       of CompuNet, Inc. for all periods presented.



 ITEM 2-

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

OVERVIEW

         Internet America, Inc. is a leading Internet service provider ("ISP")
in the southwestern United States. The Company provides a wide array of Internet
services tailored to meet the needs of individual and business customers,
including customers with little or no online experience. With more than 53,000
customers, primarily in the North Texas area, the Company believes that it has
achieved one of the highest user densities per point of presence of any ISP in
the United States. This user density has enabled the Company to realize
substantial marketing, network and operating efficiencies.

STATEMENT OF OPERATIONS

       The Company's access revenues are derived primarily from individual
dial-up Internet access, whether analog or ISDN, and revenues derived from
value-added services, such as multiple e-mail boxes and personalized e-mail
addresses. The Company derives business services revenues primarily from
dedicated connectivity, bulk dial-up access, web services and bulk access to
newsgroups. Other revenues are derived primarily from advertising fees.

A brief description of each element of the Company's operating expenses follows:

       Connectivity and operations expenses consist primarily of setup costs for
new customers, telecommunication costs, and wages of network operations and
customer support personnel. Setup costs include cost of diskettes and other
media, manuals, packaging and delivery costs. The Company does not defer
customer setup costs, but expenses such items as incurred. Connectivity costs
include (i) fees paid to telephone companies for customers' dial-up connections
to the Company's network and (ii) fees paid to backbone providers for
connections from the Company's network to the Internet.

       Sales and marketing expenses consist primarily of creative, media and
production costs, and call center employee wages. These expenses include the
cost of the Company's television and billboard campaigns and other advertising.
The Company does not defer any advertising costs, but expenses such items as
incurred. The Company expects to significantly increase its level of marketing
activities as it expands into new markets.

       General and administrative expenses consist primarily of accounting and
administrative wages, professional services, rent and other general business
expenses.

       As the Company expands into new markets, both costs of operations and
general and administrative expenses will increase. The early phases of entering
new markets will involve substantial expenditures on advertising, customer care
and other operating needs.

       Depreciation is computed using the straight line method over the
estimated useful life of the assets. The Company's data communications
equipment, computers, data server and office equipment are depreciated over
three years. The Company depreciates its furniture, fixtures and leasehold
improvements over five years. The costs of acquired subscriber bases are
amortized over three to five years.

       Total revenues. Total revenues increased by $692,000, or 27.3%, to $3.2
million for the three months ended December 31, 1998, from $2.5 million for the
three months ended December 31, 1997. Access revenues increased by $672,000, or
30.1%, to $2.9 million for the three months ended December 31, 1998, from $2.2
million for the same period in the prior year. The increase in access revenues
is attributable to an increase in the number of dial-up customers from 44,600 at
December 31, 1997, to 53,500 at December 31, 1998. Business services revenues
increased by $14,000, or 4.8%, to $303,000 for the three months ended December
31, 1998, but declined as a percentage of total revenues as the Company
continues to focus its growth strategy on the consumer dial-up market.

       Connectivity and operations. Connectivity and operations expenses
increased by $186,000, or 16.1%, to $1.3 million for the three months ended
December 31, 1998, but decreased as a percentage of total revenues to 41.4%
compared to 45.4% for the same period in the prior year. The decrease in
expenses as a percentage of revenues is due to cost efficiencies achieved for
wages and connectivity resulting from greater user density in existing markets.

       Sales and marketing. Sales and marketing expenses increased by $755,000,
or 381%, to $954,000 for the three months ended December 31, 1998, compared to
$199,000 for the same period in the prior year, when the Company had suspended
virtually all advertising efforts. During the quarter ended December 31, 1998,
the Company launched its marketing campaign in four new markets and continued
its advertising efforts in North Texas. Total sales and marketing expenses for
the period ended December 31, 1998, of $954,000 included $803,000 in
television, print and billboard advertising.

       General and administrative. General and administrative expenses increased
by $209,000, or 46.8%, to $654,000 for the three months ended December 31, 1998,
from $446,000 for the three months ended December 31, 1997. As a percentage of
total revenues, general and administrative expenses increased to 20.3% for the
three months ended December 31, 1998, from 17.6% for the same period in the
prior year. The percentage increase is primarily due to increases in wages and
professional services related to the Company's growth and write-offs of bad debt
during the period.

       Depreciation and amortization. Depreciation and amortization increased by
$38,000, or 10.4%, to $401,000 for the three months ended December 31, 1998,
from $363,000 for the same period in the prior year. The increase is due to
routine purchases of property and equipment and an acquisition of a subscriber
base in December 1997, resulting in additional amortization expense.

       Interest expense. Interest expense decreased by $126,000, or 81.1%, to
$29,000 for the three months ended December 31, 1998, from $156,000 for the same
period in the prior year. During the three months ended December 31, 1997, the
Company had several notes payable to shareholders bearing interest at 18%. In
July 1998, the shareholder notes were restructured and the interest rate
decreased from 18% to prime rate.

       Total revenues. Total revenues increased by $1.4 million, or 28.7%, to
$6.4 million for the six months ended December 31, 1998, from $4.9 million for
the same period in the prior year. Virtually all of the increase in total
revenues is attributable to an increase in access revenues resulting from growth
in customer count. Access revenues increased $1.4 million, or 32.6%, and the
number of access customers increased by 20% to 53,500 at December 31, 1998.
Business services revenues decreased by $17,000, or 3.0%, to $532,000 for the
six months ended December 31, 1998, from the same period in the prior year.
The decrease in business services revenues is attributable to a planned change 
in the mix of services offered to include more web hosting and other 
lower-priced products for the six months ended December 31, 1998.

       Connectivity and operations. Connectivity and operations expenses
increased by $264,000, or 11.7%, to $2.5 million for the six months ended
December 31, 1998, compared to the same period in the prior year. Connectivity
and operations expenses as a percentage of total revenues decreased from 45.7%
for the six months ended December 31, 1997, to 39.6% for the six months ended
December 31, 1998. The decrease as a percentage of revenues is due to cost
efficiencies achieved for wages and connectivity resulting from greater user
density in existing markets.

       Sales and marketing. Sales and marketing expenses increased by $1.3
million, or 444%, to $1.5 million for the six months ended December 31, 1998,
compared to the same period in the prior year. The Company suspended virtually
all of its advertising efforts during calendar 1997. In January 1998, the
Company launched a new marketing campaign with television and billboard
advertising that continued throughout the calendar year. In December 1998, the
Company launched its marketing campaign in four new markets, while continuing
its advertising efforts in North Texas. Total sales and marketing expenses of
$1.5 million for the six months ended December 31, 1998, included $1.2 million 
in television, print and billboard advertising.

       General and administrative. General and administrative expenses increased
by $372,000, or 44.0%, to $1.2 million for the six months ended December 31,
1998, from $846,000 for the same period in the prior year. As a percentage of
revenues, general and administrative expenses increased to 19.1% for the six
months ended December 31, 1998, from 17.1% for the same period in the prior
year. The increase as a percentage of revenues is primarily due to increases in
wages and professional services related to the Company's growth and write-offs
of bad debt during the period.

       Depreciation and amortization. Depreciation and amortization increased by
$61,000, or 8.5%, to $788,000 for the six months ended December 31, 1998, from
$727,000 for the same period in the prior year. The increase is due to routine
purchases of property and equipment and an acquisition of a subscriber base in
December 1997, resulting in additional amortization expense.

       Interest expense. Interest expense decreased by $185,000, or 63.6%, to
$106,000 for the six months ended December 31, 1998, compared to the same period
in the prior year. During the six months ended December 31, 1997, the Company
had several notes payable to shareholders bearing interest up to 18%. In June
1998, the shareholder notes were restructured and the interest rate decreased
from 18% to prime rate.


LIQUIDITY AND CAPITAL RESOURCES

       The Company has financed its operations to date primarily through (i)
public and private sales of equity securities, (ii) loans from shareholders and
third parties and (iii) cash flows from operations. The Company completed an
initial public offering in December 1998, issuing 1,700,000 shares of common
stock at a price of $13 per share. The proceeds of the Offering were $19.8
million, net of underwriting discounts and expenses. Upon completion of the
Offering, the Company repaid the remaining balances of shareholder notes and
related accrued interest which totaled $1.4 million. In addition, the Company
repaid certain other notes and capital lease obligations totaling $625,000. As a
result, the Company had no long-term obligations at December 31, 1998.

       Cash provided by operating activities totaled $780,000 for the six months
ended December 31, 1998, compared to $1.1 million for the same period in the
prior year. Payments for advertising costs of $1.3 million were included in the
six months ended December 31, 1998, versus $110,000 for the same period in the
prior year.

       Cash used in investing activities was $485,000 for the six months ended
December 31, 1998, and consisted of routine purchases of property and equipment 
to maintain network reliability.


<PAGE>   11


       For the six months ended December 31, 1998, cash provided by financing 
activities totaled $16.9 million, which consisted of proceeds from the Offering
of $19.8 million less payments of $2.9 million to service and retire shareholder
notes and long-term obligations.

       At December 31, 1998, the Company had cash on hand of $17.8 million. The
Company estimates that its funding needs for the next twelve months can be met
by cash on hand and cash flows from operations. After such period, depending on
its financial condition and results of operations, the Company may require
additional equity or debt financing. There can be no assurance that additional
financing will be available when required. The Company is currently in
discussions with various lenders concerning a possible credit facility, but
there can be no assurance that the Company will enter into any facility, and if
so, on what terms.


RECENT ACCOUNTING PRONOUNCEMENTS

       Effective with the first quarter of 1998, the Company was subject to the
provisions of Statement of Financial Accounting Standards No. 130 ("SFAS 130"),
"Reporting Comprehensive Income" and Statement of Financial Accounting Standards
No. 131 ("SFAS 131"), "Disclosures about Segments of an Enterprise and Related
Information." Neither statement had any impact on the Company's financial
statements as the Company does not have any items of "comprehensive income." The
Company will continue to review these statements over time, in particular, SFAS
131, to determine if any additional disclosures are necessary based on evolving
circumstances.


YEAR 2000

       The Year 2000 issue is the result of computer programs using two digits
rather than four to define the applicable year. Date-sensitive software may
recognize a date using "00" as the year 1900 rather than the year 2000. This
could result in system failures or miscalculations, causing disruptions of
operations, including, among others, a temporary inability to process
transactions, send invoices or engage in similar normal business activities.

       State of Readiness

       In order to address Year 2000 issues, the Company has developed and is
implementing a plan for the Company to become Year 2000 ready (the "Year 2000
Plan"). The Year 2000 Plan covers: (i) software products which are supplied by
the Company to its customers and (ii) the Company's information and other
systems technology. In addition, the Year 2000 Plan calls for the Company to
identify and assess the systems and services of the Company's major vendors,
third party network service providers and other material service providers
("Third Party Systems"), and take appropriate remedial actions and develop
contingency plans where appropriate in connection with such Third Party Systems.

       The Company supplies its customers with a software package that, among
other things, allows its customers to access the Company's services. The
software package consists of internally developed software which is bundled with
third party software (collectively, the "Installation Package"). The Company
believes that the current shipping version of its software package is Year 2000
ready. In addition, the Company believes that substantially all of its customer
base is presently using a version of the Installation Package that is Year 2000
ready.

       The Company continues to evaluate its information and other systems
technology to identify and eliminate Year 2000 issues in order to achieve Year
2000 readiness. The Company has performed a review of its more critical Third
Party Systems and has surveyed the publicly available statements issued by
vendors of such systems. Most of the Company's critical third-party providers
have made representations to the effect that they are, or will be, Year 2000
compliant. The Company, however, has not undertaken an in-depth evaluation of
its critical or other third-party providers in relation to the Year 2000 issue,
and furthermore the Company has no control over whether its third-party
providers are, or will be, Year 2000 compliant.

       Costs

       There are no significant historical costs associated with the Company's
Year 2000 readiness efforts and the magnitude of any future costs will depend
upon the nature and extent of any problems that are identified.

       Risks

       The failure by the Company to correct a material Year 2000 problem could
result in a complete failure or degradation of the performance of the Company's
network or other systems, including the disruption of operations, a temporary
inability to process transactions, send invoices or engage in similar normal
business activities. Presently, however, the Company believes that its most
reasonably likely worst case scenario related to the Year 2000 is associated
with potential concerns with third-party services or products. Specifically, the
Company is heavily dependent on a significant number of third-party vendors to
provide both network services or equipment. A significant Year 2000-related
disruption of the network services or equipment provided to the Company by
third-party vendors could cause customers to consider seeking alternate
providers or cause an unmanageable burden on customer service and technical
support, which in turn could materially and adversely affect the Company's
results of operations, liquidity and financial condition. The Company is not
presently aware of any vendor-related Year 2000 issue that is likely to result
in such a disruption. Although there is inherent uncertainty in the Year 2000
issue, the Company expects that as it progresses with its Year 2000 Plan, the
level of uncertainty about the impact of the Year 2000 issue on the Company will
be reduced and the Company should be better positioned to identify the nature
and extent of material risk to the Company as a result of any Year 2000
disruptions.

       Contingency Plans

       Due to the current stage of the Company's Year 2000 Plan, the Company is
currently unable to fully assess its risks and determine what contingency plans,
if any, need to be implemented. As the Company progresses with its Year 2000
Plan and identifies specific risk areas, the Company intends to timely implement
appropriate remedial actions and contingency plans.

       The estimates and conclusions herein contain forward-looking statements
and are based on management's best estimates of future events. The Company's
expectations about risks, future costs, and the timely completion of its Year
2000 efforts are subject to uncertainties that could cause actual results to
differ materially from what has been discussed above. Factors that could
influence risks, amount of future costs and the effective timing of remediation
efforts include the Company's success in identifying and correcting potential
Year 2000 issues and the ability of third parties to appropriately address their
Year 2000 issues.


"SAFE HARBOR" STATEMENT

       The following "Safe Harbor" Statement is made pursuant to the Private
Securities Litigation Reform Act of 1995. Certain of the Statements contained in
the body of this Report are forward-looking statements (rather than historical
facts) that are subject to risks and uncertainties that could cause actual
results to differ materially from those described in the forward-looking
statements. With respect to such forward-looking statements, the Company seeks
the protections afforded by the Private Securities Litigation Reform Act of
1995. These risks include, without limitation, (1) that the Company will not
retain or grow its subscriber base, (2) that the Company will fail to be
competitive with existing and new competitors, (3) that the Company will not be
able to sustain its current growth, (4) that the Company will not adequately
respond to technological developments impacting the Internet, and (5) that
needed financing will not be available to the Company if and as needed. This
list is intended to identify certain of the principal factors that could cause
actual results to differ materially from those described in the forward-looking
statements included elsewhere herein. These factors are not intended to
represent a complete list of all risks and uncertainties inherent in the
Company's business, and should be read in conjunction with the more detailed
cautionary statements included in the Company's other publicly filed reports and
documents.
