                     INTERNET AMERICA, INC. AND SUBSIDIARIES
              NOTES TO CONSOLIDATED CONDENSED FINANCIAL STATEMENTS
                                   (UNAUDITED)

1. Basis of Presentation

       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 of operations
       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 for the year ended June 30,
       1999, included in the Company's Annual Report on Form 10-KSB (File No
       000-25147).

2. Earnings Per Share

       There are no adjustments required to be made to net loss for the purpose
       of computing basic and diluted earnings per share ("EPS"). During the
       quarter ended December 31, 1999, options to purchase approximately
       1,202,000 shares of common stock 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. During the quarter ended
       December 31, 1999, options to purchase 127,784 shares of common stock
       were exercised.

3. Business Combinations

       On November 22, 1999, the Company acquired all of the outstanding shares
       of PDQ.Net, Inc. ("PDQ.Net"), a Houston-based ISP, in exchange for
       2,425,000 shares of the Company's common stock. The Company also issued
       options to purchase 352,917 shares of the Company's common stock with a
       weighted average exercise price of $1.62 per share in replacement of all
       of the outstanding stock options of PDQ.Net. The total value of the stock
       and options exchanged by the Company was approximately $29.9 million,
       excluding closing costs, based on the November 22, 1999 closing price of
       the Company's stock, adjusted to reflect restrictions on the transfer of
       certain shares. The acquisition is accounted for using the purchase
       method in the accompanying condensed financial statements. Goodwill
       arising from the transaction aggregates approximately $32.6 million and
       is being amortized using the straight-line method over a period of three
       years commencing November 22, 1999.

       Pro Forma amounts of total revenues, net loss, and net loss per share for
       the six months ended December 31, 1999 and 1998, assuming the acquisition
       had occurred at the beginning of each period, are as follows:

ITEM 2-

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

This section contains "forward-looking statements" within the meaning of Section
27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act
of 1934. These statements, identified by words such as "anticipate," "believe,"
"estimate," "should," "expect" and similar expressions, include our expectations
and objectives regarding our future financial position, operating results and
business strategy. These statements reflect the current views of management with
respect to future events and are subject to risks, uncertainties and other
factors that may cause our actual results, performance or achievements, or
industry results, to be materially different from those described in the
forward-looking statements. We do not intend to update the forward-looking
information to reflect actual results or changes in the factors affecting such
forward-looking information. Our Annual Report on Form 10-KSB for the fiscal
year ended June 30, 1999, filed with the Securities and Exchange Commission on
September 15, 1999, discusses some additional important risk factors that could
cause our actual results to differ materially from those in such forward-looking
statements.


OVERVIEW

      Internet America is an Internet service provider ("ISP") that provides a
wide array of Internet services tailored to meet the needs of individual and
business subscribers. We afford our subscribers a high quality Internet
experience with fast, reliable service and responsive customer care. As of
December 31, 1999, we served approximately 147,000 subscribers in the
southwestern United States.

      The rapid growth of the Internet has resulted in increased competition for
existing services and increased demand for new products and services. Increases
in demand and a surge in Internet users have fostered an increase in the number
of ISPs providing access to the Internet. Our competitors have begun to
advertise in our existing markets with aggressive new promotions or offers of
free Internet access. We believe we are well positioned to deal with these
competitive forces by continuing to build high user density and maintaining a
rational business plan.

      Rapid growth and high user density are the cornerstones of our business
strategy. We will continue to pursue an ambitious growth strategy, but in a
controlled manner. Our goal is to rapidly create user density in specific
regions with a view towards positive EBITDA (Earnings Before Interest, Taxes,
Depreciation, and Amortization) in the near future.

      Recent technological developments have allowed for the propagation of
broadband, a transmission medium that can carry numerous voice, video, and data
channels simultaneously. The emergence of low-cost broadband solutions will
significantly impact the ability of many ISPs to compete. We are committed to
being a leader in offering broadband solutions to individuals and businesses.
High-speed connectivity is essential to the commercially viable deployment of
new, value-added services such as Internet telephony, particularly Voice Over
Internet Protocol (VoIP), video and audio programming distribution and other
high bandwidth applications. We believe we are well positioned to efficiently
market and deploy our DSL products due to the high density of our subscriber
base.

      Given the increased level of competition in the industry for new
subscribers, we will be more selective with regard to investing in direct
response advertising. We plan to concentrate our direct response advertising
more heavily in markets where we have established branding than in new markets.
We have found that the most effective way to initially penetrate new markets is
through an aggressive acquisition strategy. Management believes the level of
consolidation in the industry will escalate, and a viable acquisition strategy
is the most efficient way to rapidly build market share.

      We expect our total sales and marketing expenses to remain relatively
stable as a percentage of total revenue. However, we anticipate a lower cost of
adding new subscribers by using a market development fund provided by a
telecommunications company with which we have partnered to deliver DSL.



<PAGE>   7

      The execution of our acquisition strategy will cause an increase in our
amortization expense as the costs of purchasing the subscriber bases are written
off. In the coming fiscal years we expect to report net losses, primarily due to
amortization expense, while generating positive EBITDA. There can be no
assurance we will be able to achieve or sustain positive EBITDA or net income in
the future.

      We expect general and administrative expenses to increase to support our
growth. Connectivity costs will increase after acquisitions, since there is some
duplication of inbound telephone connectivity and Internet connectivity during
the transition period. However, we believe we can quickly transition even
sizable acquisitions and realize connectivity and networking economies of scale
within two quarters of an acquisition.

      We have an accumulated deficit of $17.0 million at December 31, 1999 and
have had annual operating losses since inception as a result of building network
infrastructure and rapidly increasing market share.


RECENT ACQUISITIONS

      On November 22, 1999, we acquired all of the issued and outstanding
securities of PDQ.Net for 2,425,000 shares of our common stock. We also issued
options to purchase 352,917 shares of the Company's common stock with a weighted
average exercise price of $1.62 per share in replacement of all of the
outstanding stock options of PDQ.Net. As a result of the purchase, PDQ.Net
became a wholly owned subsidiary of Internet America, Inc. The assets of
PDQ.Net include approximately 43,000 individual and corporate Internet access
accounts and the computer equipment used to service those accounts. We intend to
continue to use these assets to provide Internet access to customers. The total
value of the stock and options exchanged by the Company, excluding closing
costs, was approximately $29.9 million based on the November 22, 1999 closing
price of the Company's stock, adjusted to reflect restrictions on the transfer
of certain shares. The transaction is accounted for as a purchase.


STATEMENT OF OPERATIONS

      Access revenues are derived primarily from individual Internet access,
whether dial-up, ISDN, or DSL and value-added services, such as multiple e-mail
boxes and personalized e-mail addresses. Business services revenues are derived
primarily from dedicated connectivity, bulk dial-up access and Web services.

      A brief description of each element of our operating expenses follows:

            Connectivity and operations expenses consist primarily of setup
      costs for new subscribers, telecommunications costs, and wages of network
      operations and customer support personnel. Connectivity costs include (i)
      fees paid to telecommunications companies for subscribers' connections to
      our network and (ii) fees paid to backbone providers for connections from
      our network to the Internet.

            Sales and marketing expenses consist primarily of creative and
      production costs, costs of media placement, call center wages and
      management salaries. Advertising costs are expensed as incurred.

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

            Depreciation is computed using the straight line method over the
      estimated useful lives of the assets. Data communications equipment,
      computers, data servers and office equipment are depreciated over three
      years. We depreciate furniture, fixtures and leasehold improvements over
      five years. Purchased subscriber bases are amortized over three years. The
      assets and liabilities acquired in business combinations are recorded at
      estimated fair values. The excess of the cost of the net assets acquired
      over their fair value is recorded as goodwill and amortized over an
      estimated life of three years. Depreciation and amortization will increase
      substantially during fiscal 2000 due to the acquisition of PDQ.Net and
      other recent acquisitions.

      Our business is not subject to any significant seasonal influences.

      Total revenue. Total revenue increased by $2.8 million, or 66.1%, to $7.0
million for the three months ended December 31, 1999, from $4.2 million for the
three months ended December 31, 1998. The majority of the increase in total
revenue is attributable to the increase in access revenue of $2.1 million, or
58.9%, to $5.8 million for the three months ended December 31, 1999, from $3.6
million for the same period in 1998. Approximately $800,000 of the increase in
access revenue is attributable to the acquisition of PDQ.Net, which had
approximately 41,000 subscribers on the closing date of November 22, 1999. The
remaining $1.3 million increase in access revenue is attributable to an increase
in the number of other subscribers from 67,500 at December 31, 1998, to 106,000
at December 31, 1999. Business services revenue increased from $598,000 for the
three months ended December 31, 1998 to $1.2 million for the same period in
1999. The increase in business services revenue is primarily due to the
acquisition of NeoSoft, Inc. (NeoSoft) on June 30, 1999. Over half of NeoSoft's
total revenue relates to business services. PDQ.Net also contributed $312,000 of
business services revenue during the quarter. Other revenue consists primarily
of peripheral equipment sales, sales tax refunds, and other miscellaneous
revenue.

      Connectivity and operations. Connectivity and operations expense increased
by $1.7 million, or 78.8%, to $3.9 million for the three months ended December
31, 1999 from $2.2 million for the three months ended December 31, 1998. As a
percentage of revenue, connectivity and operations expense increased to 55.9%
for the three months ended December 31, 1999, from 52.0% for the same period in
1998. The increase as a percentage of revenue is due primarily to additional
connectivity related to our entry into new markets and the development of our
DSL products.

      Sales and marketing. Sales and marketing expense increased by $335,000, or
27.6%, to $1.5 million for the three months ended December 31, 1999, compared to
$1.2 million for the same period in 1998, but decreased as a percentage of
revenue to 22.0% for the three months ended December 31, 1999 from 28.6% for the
same period in 1998. The dollar increase is due to the acquisition of PDQ.Net
and the expansion of our marketing program to nine markets in 1999 compared to
four in 1998. The decrease as a percentage of revenue is due primarily to a
restriction of marketing efforts to markets with established branding.

      General and administrative. General and administrative expense increased
by $868,000, or 93.4%, to $1.8 million for the three months ended December 31,
1999, from $929,000 for the three months ended December 31, 1998. General and
administrative expense as a percentage of total revenue increased to 25.6% for
the three months ended December 31, 1999, from 21.9% for the same period in
1998, primarily due to administrative support related to our growth strategy.

      Depreciation and amortization. Depreciation and amortization increased by
$2.0 million to $2.5 million for the three months ended December 31, 1999, from
$496,000 for the same period in 1998. The increase is due to the amortization of
recently acquired subscriber bases and goodwill, along with additional
depreciation expense related to routine upgrades of our network facilities.
Approximately $1.9 million of the total increase in depreciation and
amortization relates to amortization of goodwill arising from the PDQ.Net and
NeoSoft acquisitions.

      Interest income and expense. We realized $13,000 of interest income during
the three months ended December 31, 1999, compared to interest expense of
$62,000 for the same period in 1998. During the three months ended December 31,
1998, several notes payable to shareholders were outstanding, resulting in
interest expense of $62,000 for the period. These notes payable were retired
with part of the proceeds from our initial public offering in December 1998.

      Total revenue. Total revenue increased by $4.5 million, or 53.6%, to $12.9
million for the six months ended December 31, 1999, from $8.4 million for the
six months ended December 31, 1998. The majority of the increase in total
revenue is attributable to the increase in access revenue of $3.3 million, or
45.1%, to $10.5 million for the six months ended December 31, 1999, from $7.2
million for the same period in 1998. Approximately $1.4 million of the increase
in access revenue is attributable to the acquisitions of PDQ.Net and NeoSoft,
while the remainder is attributable to other growth of our customer base.
Business services revenue increased by $1.0 million, or 88.0%, to $2.1 million
for the six months ended December 31, 1999, from $1.1 million for the same
period in 1998, primarily as a result of the NeoSoft and PDQ.Net acquisitions.



<PAGE>   11



      Connectivity and operations. Connectivity and operations expense increased
by $2.8 million, or 66.8%, to $7.1 million for the six months ended December 31,
1999 from $4.2 million for the six months ended December 31, 1998. As a
percentage of revenue, connectivity and operations expense increased to 55.0%
for the six months ended December 31, 1999, from 50.7% for the same period in
1998. The increase as a percentage of revenue is due primarily to additional
connectivity purchases related to our entry into new markets and the development
of our DSL products.

      Sales and marketing. Sales and marketing expense increased by $1.0
million, or 47.6%, to $3.0 million for the six months ended December 31, 1999,
compared to $2.1 million for the same period in 1998, but decreased as a
percentage of revenue to 23.7% for the six months ended December 31, 1999 from
24.6% for the same period in 1998. The dollar increase is due primarily to the
expansion of our marketing program which, until December 1998, was limited to
North Texas. We currently advertise in nine markets throughout Texas.

      General and administrative. General and administrative expense increased
by $1.4 million, or 80.2%, to $3.2 million for the six months ended December 31,
1999, from $1.8 million for the six months ended December 31, 1998. General and
administrative expense as a percentage of total revenue increased to 24.7% for
the six months ended December 31, 1999, from 21.1% for the same period in 1998,
primarily due to administrative support related to our growth strategy.

      Depreciation and amortization. Depreciation and amortization increased by
$2.9 million to $3.9 million for the six months ended December 31, 1999, from
$1.0 million for the same period in 1998. Approximately $2.6 million of the
increase relates to amortization of goodwill arising from the acquisitions of
PDQ.Net and NeoSoft.

      Interest income and expense. We realized $50,000 of interest income during
the six months ended December 31, 1999, compared to interest expense of $171,000
for the same period in 1998. This change resulted primarily from the repayment
of several interest bearing notes payable to shareholders with part of the
proceeds of our initial public offering in December 1998 and the subsequent
reinvestment of those proceeds, which generated interest income for the six
months ended December 31, 1999.

LIQUIDITY AND CAPITAL RESOURCES

      We have financed our 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. We completed an initial public
offering of our common stock in December 1998 and received net proceeds of
approximately $19.8 million. After the offering, we repaid approximately $2.1
million in shareholder notes and certain other indebtedness. As of December 31,
1999, cash and cash equivalents on hand totaled $1.7 million.

      Cash used in operating activities totaled $1.9 million for the six months
ended December 31, 1999, compared to cash provided by operating activities of
$426,000 for the same period in 1998. Increases in sales and marketing expenses
of $1.0 million and increases in general and administrative expenses of $1.4
million related to our growth strategy contributed to additional cash used in
operations for the six months ended December 31, 1999, as compared to the same
period a year ago.

      Cash used in investing activities totaled $2.4 million for the six months
ended December 31, 1999 and consisted of $2.0 million in business and subscriber
acquisitions and $425,000 of routine purchases of property and equipment to
expand and upgrade our network totaling $425,000.

      Cash provided by financing activities totaled $191,000 for the six months
ended December 31, 1999 and consisted of proceeds of $500,000 from the exercise
of stock options by option holders less payments of $309,000 to service
long-term obligations.

      We estimate that cash on hand of $1.7 million at December 31, 1999 along
with cash provided by operations will be sufficient for meeting our working
capital needs for fiscal 2000 with regard to continuing operations in existing
markets. Additional financing will be required to fund acquisitions or expansion
into new markets.

      We are currently in discussions with various lenders concerning a possible
credit facility, but there can be no assurance that we will enter into any
facility and, if so, on what terms. In addition, we have arranged capital
financing to fund a portion of equipment purchases during this fiscal year which
are estimated to total approximately $1.4 million.


<PAGE>   12



         If additional capital financing arrangements, including public or
private sales of debt or equity securities, or additional borrowings from
commercial banks, are insufficient or unavailable, or if we experience
shortfalls in anticipated revenues or increases in anticipated expenses, we will
have to modify our operations and growth strategies to match available funding.
In such case, it is likely that our advertising expenditures would be downscaled
to a level where positive cash flows are generated from operations. We have no
long term advertising commitments, and our scheduled television commercials may
be cancelled with less than two weeks notice.

YEAR 2000

         The Year 2000 issue relates to computer programs that use two digits
rather than four digits to define an applicable year. Software may recognize a
date as the year 1900 rather than the year 2000, which could result in system
failures or miscalculations, causing disruptions of operations. This could cause
a temporary inability to process transactions, send invoices, route our
subscribers' Internet traffic or engage in similar normal business activities.

         We have developed a Year 2000 Plan (the "Plan") which is designed to
address Year 2000 issues so that we will be prepared for any problems arising
from the arrival of the Year 2000. The Plan covers: (i) internally developed and
vendor supplied software products which are provided to our subscribers; (ii)
network software and hardware, including routing and server components and
telephony systems; (iii) network operations and network support systems; (iv)
software and hardware components used by our customer care and sales
departments; and (v) other office infrastructure components. Additionally, the
Plan is designed to identify and assess our third party network service
providers and major vendors ("Third Party Systems") in order to develop and
implement action and contingency plans where appropriate in connection with
these Third Party Systems.

         For the internal systems described above, the Plan requires that we

         1)       investigate our internal software and hardware components in
                  order to assess the current state of Year 2000 readiness,

         2)       prepare an evaluation of the resources necessary to upgrade
                  our components to become Year 2000 ready,

         3)       develop and execute action plans to procure the necessary
                  resources and implement fixes to the problems that exist,

         4)       re-evaluate the upgraded components, and

         5)       repeat steps 2 through 4, if necessary.

         For our Third Party Systems, the plan requires that we

         1)       investigate the products and services provided by Third Party
                  systems in order to assess the current state of Year 2000
                  readiness with respect to these external suppliers, including
                  a survey of the publicly available statements issued by
                  vendors of those systems,

         2)       inquire of our Third Party Systems as to their plans to remedy
                  any issues outstanding relating to Year 2000 issues,

         3)       evaluate alternatives to existing Third Party Systems
                  relationships in cases where Year 2000 readiness is
                  questionable, and

         4)       take the appropriate steps to become Year 2000 ready.

         In addition to the preparation work on both internal and external
systems, the Plan also details contingency plans which are designed to deal with
unanticipated Year 2000 issues, should they arise.

STATE OF READINESS

         To date, we have experienced no material Year 2000 problems that could
harm or threaten to harm our business. Our software products, network
applications and system hardware components were tested and continue to be
monitored. The few problems relating to Year 2000 testing that we experienced
were addressed through upgrades or replacements. Additionally, we investigated
our Third Party Systems to assess their Year 2000 readiness and upgraded or
replaced noncompliant Third Party Systems.



<PAGE>   13



      We supply our subscribers with a software package that, among other
things, allows subscribers to access our services. The software package consists
of internally developed software which is bundled with third party software. We
believe that the current version of our software package is Year 2000 ready. In
addition, we believe that substantially all of our customer base is presently
using a version of the software package that is Year 2000 ready.

      Our network components consist primarily of routers and servers. Routers
function as network traffic coordinators and determine the paths that individual
packets of data will take to get from point A to point B. The primary component
of router functionality is the software which manages the data traffic. We
believe that the current version of the software within the routers is Year 2000
ready. Servers act as the processing centers for the management of information.
Our servers generally utilize the UNIX operating system or internally developed
systems, all of which we believe are currently Year 2000 ready. The software
component of our telephone system, which manages all inbound and outbound phone
and fax capabilities, was upgraded, and we believe it is currently Year 2000
ready.

      Our NOCC monitors the internal and external network operations using
specialized software provided by Third Party Systems. Our network operations
software has been upgraded, and we believe it is currently Year 2000 compliant.

      Our customer care and sales departments utilize standardized desktop
computers to interact with our internal data systems. We do not believe that
significant issues exist relating to our customer care and sales departments'
systems. Other office infrastructure includes, among others, our administrative
computer systems, fax machines and copiers. We do not expect significant Year
2000 issues to exist with these devices.

COSTS

      We have incurred expenses of approximately $85,000 in connection with the
implementation of the Plan. We do not expect to incur significant additional
expenses related to the execution of the Plan.

RISKS

      Although we have experienced no significant Year 2000 problems to date,
they could still occur. Our failure to correct a material Year 2000 problem
could result in a complete failure or degradation of the performance of our
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, we believe that our most reasonably
likely worst case scenario related to the Year 2000 is associated with potential
concerns with third party services. Specifically, we are heavily dependent on a
significant number of third party vendors to provide network services. A
significant Year 2000-related disruption of the network services provided by
Third Party Systems could cause subscribers to seek alternative providers or
cause an unmanageable burden on operations, liquidity and financial condition.
We are not presently aware of any Third Party Systems issue that is likely to
result in such a disruption.

CONTINGENCY PLANS

      We believe we have assessed the risks involved with the Year 2000 issue
and have established procedures to minimize any effect of an unidentified or
Third Party Systems created Year 2000 problem. These procedures include
identifying recovery strategies and providing personnel on duty or on call
during the transition period specifically trained to deal with software failures
and Third Party Systems failures, should they occur.

      The estimates and conclusions herein contain forward-looking statements
and are based on our best estimates of future events. Our expectations about
risks, future costs and the timely completion of our 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 our
success in identifying and correcting potential Year 2000 issues and the ability
of Third Party Systems to appropriately address their Year 2000 issues.
