OVERVIEW

         ViewCast enables video communication over the Internet and other
networks through vertically-integrated components, systems, and turnkey solution
products and services. We are a leading global provider of enterprise-wide,
digital video communication solutions for both real-time and on-demand
applications. We deliver innovative networked video solutions, as well as
systems that can work with legacy video communication equipment. Our Osprey(R)
video capture cards and codecs, ViewCast(R) Encoding and Streaming Video System
and Viewpoint VBX(TM) System products deliver a wide array of video solutions
for both digital and analog video communication systems.

         As a new initiative in the year 2000, we have added video content
hosting services and will be providing professional services to meet the growing
demand from public and private sector enterprises to add or extend video
communications internally and externally. One of our hosting services,
"YourVideoOnTheWeb(TM)", is a consumeR product designed to bring streaming media
capabilities to home users and small businesses enabling them to add video
content to their web sites.

         Our customers acquire our solutions and products to enhance
communication and productivity, reduce costs and increase customer service
within corporations, educational networks, healthcare facilities, financial
institutions and government agencies, as well as between those entities, their
customers, vendors and others with whom they may communicate. Our customers use
our products to enable them to broadcast video over computer networks (streaming
video), deliver video from web sites (on-demand streaming video), provide
interactive video communication (video conferencing), and distribute video
within a network. We market, install and support our products either directly or
through arrangements with leading OEMs, system integrators, leading resellers
and application developers worldwide.

         To reflect the growing importance of the Internet as a means of
transmitting video, on April 8, 1999, we changed our name to ViewCast.com, Inc.
from MultiMedia Access Corporation. As part of a strategic emphasis on sales,
marketing and strategic planning, we added three senior executives within the
last five months: President and Chief Executive Officer George C. Platt; Senior
Vice President of Sales and Marketing Harry E. Bruner; and Chief Financial
Officer Laurie L. Latham. These executives are now leading the organization
along with certain of our continuing executives, including Neal Page, Vice
President/General Manager of Osprey(R) Technologies Division and David T.
Stoner, Vice President of Operations. These management changes reflect our
commitment to the new strategies formulated for our existing and new markets.

INDUSTRY BACKGROUND

         Technology has merged with current business dynamics causing
unprecedented potential for growth and revenue, an increased likelihood for
confusion, and new challenges to compete and sustain position. As reported by
the 1999 Information Week Magazine Annual IT Survey, "Companies are more
aggressive than ever about adopting and deploying leading edge technologies --
based solely on the fear of being left behind."

         Within this environment, we believe businesses will increasingly seek
expert support to reduce confusion and to present solutions to their business
challenges. We believe that to meet these business challenges, there will be
increased usage of video communication products and services.

OUR SOLUTION

         As a vertically integrated provider, ViewCast provides video and media
solutions to our customers. We provide:

   o     TECHNOLOGY -- Our technology provides a competitive edge allowing us to
         differentiate our products from those of our competitors and increasing
         our ability to develop customer driven applications.

   o     PRODUCTS AND APPLICATIONS -- Our products consist of Video Subsystems,
         such as capture cards and codecs for encoding, decoding and streaming,
         and Video Systems solutions for digital and analog video applications.
         We manufacture and distribute worldwide our Osprey(R) video capture
         cards and codecs, ViewCast(R) Streaming Video solutions and Viewpoint
         VBX(TM) Systems. YourVideoOnTheWeb(TM) is a consumer Product used to
         encode video from a camcorder or VCR.

   o     EXPERTISE AND SERVICES -- Our comprehensive video expertise enables us
         to assist customers in identifying their communication needs and
         determine appropriate media mechanisms for their business requirements.
         Once established, our professional service organization will complement
         our sales engineering and training organization by offering broader
         customer solutions and support services. A significant addition will be
         our content hosting service (ViewCast Online(TM)).

RISK FACTORS

- --------------------------------------------------------------------------------
    You should consider carefully the following risk factors before deciding
                     whether to invest in our common stock.
- --------------------------------------------------------------------------------


WE HAVE SIGNIFICANT DEBT AND MAY NOT BE ABLE TO MEET OUR OBLIGATIONS.

         As of March 31, 2000, we had outstanding borrowings under a secured
line of credit in the aggregate principal amount of $2,408,827. This one-year
renewable line of credit for up to $9,000,000 is with an entity controlled by a
director and principal stockholder of ViewCast. The line of credit facility
bears interest at 12% and is due October 22, 2000 unless extended. In addition,
we are actively seeing additional capital to finance our operations and may
incur additional indebtedness in order to meet these working capital needs.

         Our indebtedness has several important consequences to our
stockholders, including, but not limited to, the following:

    o    we may be unable to obtain additional or replacement financing for
         working capital, capital expenditures, acquisitions and general
         corporate purposes;

    o    a significant portion of our cash flow from operations must be
         dedicated to the repayment of the indebtedness, thereby reducing the
         amount of cash we have available for other purposes;

    o    we may be disadvantaged as compared to our competitors as a result of
         the significant amount of debt we now owe;

    o    our ability to adjust to changing market conditions and our ability to
         withstand competition may be hampered by the amount of debt we now owe,
         and it may also make us more vulnerable in a downtrend market;

    o    our debt position and the covenants contained in certain of our loan
         documents could limit our ability to expand our business and take
         advantage of certain business opportunities; and

    o    our debt position may make us more vulnerable to economic downturns,
         limit our ability to withstand competitive pressures, and reduce our
         flexibility in responding to changing business and economic conditions.

         Our ability to pay interest and principal on the secured line of credit
will depend upon our future operating performance, which will be affected by
prevailing economic conditions and financial, business and other factors,
certain of which are beyond our control. If we are unable to service our debt,
we will be forced to pursue one or more alternative strategies such as selling

or seeking additional equity capital. We cannot assure you that any of these
strategies could be effected on terms satisfactory to us, if at all.


WE HAVE GENERATED LIMITED REVENUE AND HAVE EXPERIENCED SIGNIFICANT LOSSES. THESE
TRENDS MAY CONTINUE FOR THE FORESEEABLE FUTURE.

         We have in the past generated limited revenue and significant losses.
For the years ended December 31, 1999 and 1998, respectively, we generated
revenues of $7,270,080 and $8,027,948 and incurred losses of $8,473,674 and
$9,366,693. We anticipate that losses will continue for the foreseeable future.
In addition, our future revenues and profits or losses could be influenced by
factors beyond our control including technological changes and developments,
downturns in the economy or a decline in the desktop video conferencing or PC
industries or in targeted commercial markets. We may not be able to successfully
implement our marketing strategy, generate significant revenues or become
profitable.

         At December 31, 1999, we had substantial net operating loss carry
forwards for federal income tax purposes available to offset future taxable
income. Under Section 382 of the Internal Revenue Code of 1986, as amended,
utilization of prior net operating loss carry forwards is limited after
ownership changes, as defined in Section 382. In the event we achieve profitable
operations, any significant limitation on the utilization of net operating loss
carry forwards would have the effect of increasing our tax liability and
reducing net income and available cash resources.


THE MARKETS FOR OUR PRODUCTS ARE CHARACTERIZED BY RAPIDLY CHANGING TECHNOLOGY
AND EVOLVING INDUSTRY STANDARDS, OFTEN RESULTING IN PRODUCT OBSOLESCENCE OR
SHORT PRODUCT LIFECYCLES. OUR PROFITABILITY DEPENDS ON OUR ABILITY TO ADAPT TO
SUCH CHANGES.

         Since the markets for our products are characterized by rapidly
changing technology and evolving industry standards, often resulting in product
obsolescence or short product lifecycles, our ability to compete will depend in
large part on our ability to:

    o    introduce products in a timely manner;

    o    continually enhance and improve our systems and software products;

    o    maintain development capabilities;

    o    anticipate or adapt to technological changes and advances in the video
         communication and PC industries; and

    o    ensure continuing compatibility with evolving industry standards.


                                       8
<PAGE>   11


         If we are unable to successfully meet these challenges, we may have to
discontinue sales of our products until we can modify or redesign their
technology, which would harm our profitability.


FLUCTUATIONS IN OPERATING RESULTS COULD CONTINUE IN THE FUTURE.

         Our operating results may vary from period to period as a result of the
length of our sales cycle, purchasing patterns of potential customers, the
timing of the introduction of new products, software applications and product
enhancements by us and our competitors, technological factors, variations in
sales by distribution channels, timing of stocking orders by resellers,
competitive pricing, and generally nonrecurring system sales. Our sales order
cycle ranges from one to eighteen months, depending on the customer. The period
from the execution of a purchase order until delivery of system components to
us, assembly and shipment, at which time we recognize revenue, may range from
approximately one to four months. These factors may cause significant
fluctuations in operating results in the future.


WE NEED SIGNIFICANT CAPITAL TO OPERATE OUR BUSINESS AND MAY REQUIRE ADDITIONAL
FINANCING. IF WE CANNOT OBTAIN SUCH ADDITIONAL FINANCING, WE MAY NOT BE ABLE TO
CONTINUE OUR OPERATIONS.

         We need significant capital to design, develop and commercialize our
products. Currently available funds may be insufficient to fund operations and
growth. We are actively seeking additional capital to finance our operations. If
we are unable to obtain additional financing, we may be required to curtail our
activities. Additional financing may involve substantial dilution to the
interests of our existing stockholders. Such financing may include the issuance
of convertible debt, convertible preferred stock or other equity or debt
securities in exchange for a cash investment in us.


THERE ARE INHERENT RISKS AS WE CONTINUE TO DEVELOP AND MARKET OUR PRODUCTS.

         Product development, commercialization and continued system refinement
and enhancement efforts remain subject to all risks inherent in the development
of new products based on innovative technologies, including unanticipated
delays, expenses and technical problems or difficulties, as well as the possible
insufficiency of funds to implement development efforts, any one of which could
result in abandonment or substantial change in product commercialization. Our
success will be largely dependent upon, among other things, our products meeting
targeted cost and performance objectives of large-scale production, our ability
to adapt our products to satisfy industry standards and the timely introduction
of our products into the marketplace. There can be no assurance that, upon
wide-scale commercial introduction, our new products and software applications
will satisfy current price or performance objectives, that unanticipated
technical or other problems resulting in increased costs or material delays in
introduction and commercialization will not occur, or that our current products
and our future products will prove to be sufficiently reliable or durable under
actual operating conditions or


                                       9
<PAGE>   12


otherwise be commercially viable. Software and other technologies as complex as
those incorporated into our systems may contain errors which become apparent
subsequent to widespread commercial use. Remedying such errors could delay our
plans and cause us to incur additional costs, having a material adverse impact
on us.


WE MAY NOT BE ABLE TO COMMERCIALIZE SUCCESSFULLY ALL OF OUR PRODUCTS. IF WE
CANNOT DO SO, LOSSES WILL CONTINUE OR INCREASE.

         Our ability to reduce our losses or make profits is dependent upon the
successful commercialization of our products. We may encounter the risks,
expenses, delays, problems and difficulties frequently experienced by companies
which are shifting from the development to the commercialization of its
products. If unanticipated expenses, problems or difficulties, technical or
otherwise, prevent us from successfully commercializing our products, we will
experience continued or increased losses.


IF WE CANNOT SUCCESSFULLY EXPAND OUR OPERATIONS, WE WILL CONTINUE TO INCUR
SIGNIFICANT LOSSES.

         Successful expansion of our operations will be dependent, among other
things, on our ability to develop and maintain significant market acceptance for
our products, hire and retain skilled management, marketing, technical and other
personnel, develop and maintain an effective sales organization and enter into
satisfactory marketing arrangements, secure adequate sources of supply on a
timely basis and on commercially reasonable terms and successfully manage growth
(including monitoring operations, controlling costs and maintaining effective
quality controls).

         We may also seek to expand our operations through acquisitions. In such
an event, you may not have an opportunity to evaluate the specific merits or
risks of any potential acquisition. If we cannot successfully expand our sales
and operations or if we remain largely dependent on a limited customer base, we
will continue to incur significant losses.


WE COULD EXPERIENCE INCREASED LOSSES DUE TO POTENTIAL CREDIT LOSSES.

         Most of our sales are made to customers on an open account basis with
no collateral required. We perform ongoing credit evaluation of our customers
and maintain reserves for potential credit losses. Although such losses in the
aggregate have not exceeded management's expectations, potential credit losses
may exceed the amount reserved for such losses, harm our profitability and cause
increased losses in the future.


STRONG COMPETITION WITHIN OUR INDUSTRY MAY REDUCE OUR CUSTOMER BASE.

         The market for video communications systems and products is highly
competitive. New products based upon innovative technologies are frequently
introduced. We compete with


                                       10
<PAGE>   13


numerous well-established manufacturers and suppliers of video conferencing,
networking, telecommunications and multimedia equipment and products. Most of
our competitors possess substantially greater financial, marketing, personnel
and other resources than we do, have established reputations relating to product
design, development, manufacture, marketing and service of networking,
telecommunications and video products and have significant budgets to permit
them to implement extensive advertising and promotional campaigns to market new
products in response to competitors.

         Among our direct competitors are Zydacron, Inc., VCON, Ltd., Winnov,
L.P., First Virtual Corporation, Picturetel Corporation, Video Network
Communications, Inc., VTEL Corporation, Pinnacle Systems, Inc., Tandberg Inc.,
and Polycom, Inc. In addition, electronics manufacturers such as Intel Corp. and
Cisco Systems, Inc. actively compete for business in this market. Our
profitability depends upon our ability to successfully compete in our market.


OUR FUTURE PROFITS OR LOSSES DEPEND ON THE EFFORTS OF THIRD PARTY RESELLERS,
MANUFACTURERS AND SUPPLIERS. THESE RELATIONSHIPS MAY NOT CONTINUE.

         We use a network of resellers, consisting primarily of value-added
resellers (VARs), systems integrators and original equipment manufacturers
(OEMs) with established distribution channels to assist in the marketing of our
products and to educate potential resellers to install and service our systems.
Our future profits or losses depend on our ability to maintain and develop
relationships with VARs, systems integrators and OEMs, on the marketing efforts
of such resellers and on the ability of such resellers to provide installation
and support services. A decline in the financial prospects of particular
resellers or any of their customers, inadequate installation and support
services by resellers or our inability to contract with additional resellers
could damage our profitability or cause additional losses.

         We also depend on contract manufacturers to supply our products in
limited quantities pursuant to purchase orders. Our products may not be able to
be manufactured reliably on a large-scale basis on commercially reasonable
terms. In addition, we have been and will continue to be dependent on third
parties for the supply and manufacture of all of our component and electronic
parts, including standard and custom-designed components. We purchase components
and electronic parts pursuant to purchase orders in the ordinary course of
business and do not maintain supply agreements with such third parties. We are
substantially dependent on the ability of third-party manufacturers and
suppliers to meet our design, performance and quality specifications. Failure of
manufacturers or suppliers to supply, or delays in supplying us with systems or
components, or allocations in the supply of certain high demand components could
make us unable to meet our delivery schedules on a timely and competitive basis
and harm our profitability.


                                       11
<PAGE>   14


WE ARE SUBJECT TO GOVERNMENT REGULATION WHICH MAY IMPOSE ADVERSE COMPLIANCE
BURDENS.

         We are subject to regulations relating to electromagnetic radiation
from our products, which impose compliance burdens on us. In the event we
redesign or otherwise modify our products or complete the development of new
products, we will be required to comply with Federal Communications Commission
regulations with respect to such products prior to their commercialization.
There can be no assurance that we will be able to comply with such regulations.
In addition, new legislation and regulations, as well as revisions to existing
laws and regulations at the federal, state and local levels may be proposed in
the future affecting the video communications industries. Such proposals could
affect our operations, result in material capital expenditures, affect the
marketability of our products and limit opportunities for us with respect to
modification of our products or with respect to the development and proposal of
new products or technologies. Our foreign markets require us to comply with
additional regulatory requirements.

         The technology contained in our products may be subject to U.S. export
controls. There can be no assurance that such export controls, either in their
current form or as may be subsequently enacted, will not delay introduction of
new products or limit our ability to distribute products outside of the U.S.
Further, various countries may regulate the import of certain technologies
contained in our products. Such export or import restrictions, new legislation
or regulation or government enforcement of existing regulations could have a
material adverse effect on our business, operating results or financial
condition. There can be no assurance that we will be able to comply with
additional applicable laws and regulations without excessive cost or business
interruption, if at all, and failure to comply could have a similarly material
adverse effect.


THE LIMITED MARKET ACCEPTANCE OF VIDEO COMMUNICATIONS SYSTEMS MAY REQUIRE US TO
SPEND SUBSTANTIAL TIME AND EXPENSE MARKETING OUR PRODUCTS.

         The relatively high cost and less than television broadcast quality of
video communications systems have historically limited the market acceptance of
video communication systems. Potential customers may therefore elect to utilize
other products which they believe to be more efficient or have other advantages
over our products. This may require us to spend substantial time and effort and
incur significant expense to increase awareness and generate demand by potential
consumers as to the perceived benefits and distinctive characters of our
products in order to market successfully our products. If we cannot market
successfully our products, we will suffer additional losses.


WE HAVE A SMALL CUSTOMER BASE.

         We make a substantial portion of our sales to a small number of
customers. A loss of our sales to these customers may result in lower revenues
and increased losses.


                                       12

OUR SUCCESS IS DEPENDENT ON OUR ABILITY TO RETAIN KEY PERSONNEL. THE LOSS OF KEY
PERSONNEL COULD HARM OUR PROFITABILITY.

         Our success is largely dependent on the personal efforts of our key
personnel. Key personnel include George C. Platt-President and Chief Executive
Officer, Laurie L. Latham-Chief Financial Officer, Harry E. Bruner-Senior Vice
President of Sales and Marketing, Frederick B. Cowen-Vice President-Controller,
David T. Stoner-Vice President of Operations and Neal S. Page-Vice President and
General Manager of Osprey. All key employees, with the exception of Mr. Platt
who has executed an 18-month employment contract, are "at-will" employees. The
employment of each "at will" employee may therefore be terminated by the officer
or us at any time, for any reason or no reason. The loss of the services of key
employees or the inability to hire and retain qualified operational, financial,
technical, marketing, sales and other personnel could harm our profitability.


OUR INABILITY TO PROTECT OUR PATENTS, TRADEMARKS AND PROPRIETARY INFORMATION
COULD HARM OUR PROFITABILITY.

         We hold a U.S. patent covering certain aspects of our compressed packet
video codec. We have registered trademarks for the WorkFone(R), Osprey(R),
ViewCast(R), Viewpoint Pro(R), Personal Viewpoint(R), Multimedia Access
System(R), Call Wizard(R), Compressed Pocket Video (CPV)(R) and SLIC-Video(R)
names and have applied for trademark registration for the YourVideoOnTheWeb(TM),
Viewpoint VBX(TM), QVideo(TM), Mediapoint(TM), Conference Wizard(TM),
Envista(TM), and Viewport(TM) names.

         Our profitability will be harmed if our current or any future patents,
trademarks or proprietary information cannot be adequately protected or if
competitors develop similar or superior methods or products outside the
protection of any patent issued to us. If we infringe patents or proprietary
rights of others, we may be required to modify the design of our products,
change the name of our products or obtain a license for certain technology or
become liable for damages, all of which could harm our profitability.


RECENT VOLATILITY IN THE STOCK MARKET COULD ADVERSELY AFFECT THE TRADING PRICE
OF OUR COMMON STOCK.

         Publicly traded stocks, including our common stock, have recently
experienced substantial market price volatility. These market fluctuations may
be unrelated to the operating performance of particular companies whose shares
are traded. The trading price of our common stock is determined by the
marketplace, and may be influenced by many factors, including investor
perceptions of us and general industry and economic conditions. Due to possible
continued market volatility and to other factors, including certain risk factors
discussed in this document, there can be no assurance that the trading price of
our common stock will be at or above its current market price.


                                       13

THE EXERCISE OF OUTSTANDING WARRANTS AND OPTIONS OR THE CONVERSION OF SERIES B
PREFERRED STOCK COULD SIGNIFICANTLY DILUTE THE OWNERSHIP INTERESTS OF CURRENT
STOCKHOLDERS AND PREVENT A CHANGE IN CONTROL.

         As of March 31, 2000, there were outstanding stock options to purchase
an aggregate of approximately 2,816,564 shares of common stock at exercise
prices ranging from $1.7656 to $9.00 per share; redeemable warrants to purchase
an aggregate of 4,378,140 common shares at $4.19 per share; non-redeemable
warrants to purchase an aggregate of 985,468 common shares at exercise prices
ranging from $3.00 to $6.30 per share; and $9.45 million principal amount of
Series B Preferred Stock convertible into 2,606,896 common shares at $3.625 per
share. To the extent that outstanding options and warrants are exercised and
Series B Preferred Stock is converted, the percentage ownership of common stock
of our stockholders will be diluted.


CERTAIN PROVISIONS OF OUR CHARTER AND DELAWARE LAW MAY HAVE ANTI-TAKEOVER
EFFECTS.

         The terms of our Certificate of Incorporation, as amended, and our
ability to issue up to 5,000,000 shares of "blank check" preferred stock may
have the effect of discouraging proposals by third parties to acquire a
controlling interest in ViewCast, which could deprive stockholders of the
opportunity to consider an offer to acquire their shares at a premium. In
addition, under certain conditions, Section 203 of the Delaware General
Corporate Law would impose a three-year moratorium on certain business
combinations between us and an "interested stockholder" (in general, a
stockholder owning 15% or more of a corporation's outstanding voting stock). The
existence of such provisions may have a depressive effect on the market price of
our common stock in certain situations.


IF OUR COMMON STOCK IS DELISTED FROM NASDAQ, INVESTORS MAY NOT BE ABLE TO SELL
THEIR COMMON STOCK AT AN ACCEPTABLE PRICE, OR AT ALL.

         Our common stock is quoted on the Nasdaq Small Cap Market. In order to
continue to be listed on Nasdaq, we must maintain, among other criteria,
$2,000,000 in net tangible assets or $35,000,000 market capitalization or
$500,000 in net income for two of the prior three years and a public float of at
least 500,000 shares, a market value of public float of at least $1 million and
at least 300 shareholders. In addition, continued listing on Nasdaq requires two
market-makers and a minimum bid price of $1.00 per share. Our failure to meet
these maintenance criteria in the future may result in the delisting of our
common stock from Nasdaq. In the event that our common stock were delisted, any
trading in the common stock would be conducted in the over-the-counter market in
the so-called "pink sheets" or the "Electronic Bulletin Board" of the National
Association of Securities Dealers, Inc. As a result of such delisting, an
investor could find it more difficult to dispose of, or to obtain accurate
quotations as to the market value of, our common stock.


                                       14

NO DIVIDENDS HAVE BEEN PAID OR ARE EXPECTED TO BE PAID ON OUR COMMON STOCK.

         We have not paid any cash dividends on our common stock and do not
expect to declare or pay any cash dividends in the foreseeable future. Certain
of our debt agreements require the consent of the lender for the payment of
dividends. We cannot assure you that if we decide to pay cash dividends on our
common stock we will be able to obtain the necessary consents.


               HOW WE INTEND TO USE THE PROCEEDS FROM THE OFFERING

         ViewCast will not receive any new proceeds from the conversion of the
Series B Preferred Stock to common stock, but received gross proceeds of
$9,450,000 from the issuance of the Series B Preferred Stock in December 1998
through February 1999. Proceeds from the exercise of warrants, to the extent
they are exercised, will be used for working capital and general corporate
purposes.

         Dividends on the Series B Preferred Stock accrue at the annual rate of
$0.80 per share and are payable semi-annually in cash, or at the option of
ViewCast, in shares of common stock of ViewCast. To date ViewCast has opted to
issue common stock to offset accrued dividends on the Series B Preferred Stock
in the amount of $672,877.


                         DETERMINATION OF OFFERING PRICE

           The conversion price of the Series B Preferred Stock and exercise
price of the warrants were determined by negotiation between ViewCast and the
holders of the Series B Preferred Stock and warrant holders. In determining
these prices, ViewCast and the holders of the Series B Preferred Stock and
warrant holders considered, among other things, estimates of the business
potential of ViewCast, the management of ViewCast, its plans for the expansion
of its business base and the trading price of ViewCast common stock on Nasdaq.
Pricing did not necessarily bear any relation to earnings per share, book value
or the net worth of ViewCast. Prospective investors should not consider the
Series B Preferred Stock conversion price or the exercise price of the warrants
as necessarily indicative of the actual value of the common stock. The offering
price of the common stock after conversion of the Series B Preferred Stock and
exercise of the warrants will be determined by the current market price of the
common stock on Nasdaq. See "Selling Securityholders and Plan of Distribution."
Common stock issued as dividends on the Series B Preferred Stock is valued at
the average of the market prices for twenty (20) consecutive business days
ending ten (10) business days prior to the dividend payment date.



                                    DILUTION

         The difference between the weighted average offering price per share of
common stock and the pro forma as adjusted net tangible book value per share of
common stock after this


                                       15
<PAGE>   18


offering constitutes the dilution to investors in this offering. Net tangible
book value per share on any given date is determined by dividing the net
tangible book value (total tangible assets less total liabilities) of ViewCast
on such date by the number of shares of common stock outstanding on such date.

         The pro forma net tangible book value (deficiency) of ViewCast at
December 31, 1999 (excluding gross proceeds of $9,450,000 received from the
offering of Series B Preferred Stock in December 1998 through February 1999 and
excluding 126,008 common shares issued for payment of $672,877 of dividends on
Series B Preferred Stock) was $(471,888), or $(0.03) per share of common stock.
After giving effect to the conversion of Series B Preferred Stock, exercise of
warrants registered hereby and issuance of common stock for payment of Series B
Preferred dividends, the pro forma as adjusted net tangible book value of
ViewCast at December 31, 1999 would have been $9,123,112 or $0.54 per share,
representing an increase in pro forma as adjusted net tangible book value of
$0.57 per share to existing stockholders and an immediate dilution of $3.16 per
share (85.4%) to new investors. The following table shows the dilution to new
investors on a per share basis:

                   DESCRIPTION OF SECURITIES TO BE REGISTERED

         We are authorized to issue 40,000,000 shares of common stock, $.0001
par value per share and 5,000,000 shares of preferred stock, par value $.0001
per share. As of March 31, 2000, the 15,260,350 shares of common stock
outstanding were held by approximately 6,000 beneficial holders, and 945,000
shares of Series B Preferred Stock outstanding were held by five beneficial
owners.

COMMON STOCK

         Voting Rights -- The holders of common stock are entitled to one vote
for each share held of record on all matters to be voted on by stockholders.
There is no cumulative voting with respect to the election of directors, with
the result that the holders of more than fifty percent (50%) of the shares of
common stock voting for the election of directors can elect all of the
directors. All of the outstanding shares of common stock are fully paid and
non-assessable.

         Dividends -- Holders of shares of common stock are entitled to receive
dividends when, as and if declared by the Board of Directors in its discretion,
out of funds legally available therefor. Any dividends we pay will be mailed to
the stockholders of record as reflected in the share transfer records maintained
by our transfer agent and registrar.


                                       16
<PAGE>   19


         Liquidation Preference -- In the event of liquidation, dissolution or
winding up, the holders of common stock are entitled to share ratably in our
assets, if any, legally available for distribution to them after payment of
debts and liabilities and after provision has been made for each class of stock,
if any, having liquidation preference over the common stock. Holders of shares
of common stock have no conversion, preemptive or other subscription rights, and
there are no redemption or sinking fund provisions applicable to the common
stock.

         Stockholder Meetings -- Our Bylaws provide that the stockholders shall
have annual meetings, called by the Board of Directors, and special meetings,
called by the President, or the President or Secretary upon the written request
of a majority of the Board of Directors, or at the request in writing of the
holders owning at least a majority in amount of the entire capital stock of the
corporation issued and outstanding and entitled to vote. The stockholders
entitled to vote at such meeting must be given written notice of each such
meeting of stockholders. In the case of special meetings, the purpose or
purposes for which the meeting is called shall be given to each stockholder
entitled to vote, not less than ten or more than sixty days before the meeting.
Any notice of a stockholder meeting will be mailed to the stockholders of record
as reflected in the share transfer books maintained by our transfer agent and
registrar.

PREFERRED STOCK

         We are authorized to issue preferred stock with such designations,
rights and preferences as may be determined from time to time by the Board of
Directors. Accordingly, the Board of Directors is empowered, without stockholder
approval, to issue preferred stock with dividend, liquidation, conversion,
voting or other rights which could adversely affect the voting power or other
rights of the holders of our common stock. In the event of issuance, the
preferred stock could be utilized, under certain circumstances, as a method of
discouraging, delaying or preventing a change in control of ViewCast.

         Voting Rights of Series B Preferred Stock -- The holders of the Series
B Preferred Stock have no voting rights except for an amendment to our
Certificate of Incorporation to change the authorized shares, or par value, or
to alter or change the powers, preferences or special rights of the Series B
Preferred Stock.

         Dividends on Series B Preferred Stock -- The holders of the Series B
Preferred Stock are entitled to receive a dividend of $0.80 per share per year
payable in cash or our common stock, at our option, when, as and if declared by
the Board of Directors, out of funds legally available therefor. Any dividends
we pay will be mailed to the holders of record of the Series B Preferred Stock
as of the record date. No dividends may be paid or set apart for payment in cash
for junior stock, including the common stock, and no junior stock, including the
common stock, and stock on parity with the Series B Preferred Stock may be
repurchased or otherwise retired for value nor may funds be set apart for
payment with respect thereto, if cumulative dividends have not been paid in full
on the Series B Preferred Stock in cash or shares of common stock.

         Liquidation Preference of Series B Preferred Stock -- In the event of
our liquidation, dissolution or winding up, the holders of the Series B
Preferred Stock are entitled to be paid, out of our assets available for
distribution to stockholders, the liquidation preference of $10.00 per share,
plus, without duplication, an amount in cash or shares of common stock, at our
option, equal to all accumulated and unpaid dividends, before any distribution
is made to any holders of common stock or other class of preferred stock the
terms of which expressly provide that it ranks junior to the Series B Preferred
Stock. If upon our liquidation, dissolution or winding-up, the amount payable
with respect to the Series B Preferred Stock and all parity stock are not paid
in full, then our assets available for distribution among the holders of the
Series B Preferred Stock and any parity stock shall bear to each other the same
ratio that the full amounts payable on our liquidation, dissolution or
winding-up to the holders of Series B Preferred Stock and any parity stock bear
to each other.

         Conversion Rights of Series B Preferred Stock -- The holders of the
Series B Preferred Stock have the right to convert each share of Series B
Preferred Stock into shares of common stock at the conversion price of $3.625
per share. The conversion price may be adjusted upon a stock split or reverse
stock split of the common stock by the proportion by which the number of shares
of common stock are increased or decreased, as appropriate. Subject to specific
exceptions, if we issue common stock or equity or debt securities which are
convertible into or exercisable for shares of common stock at a price less than
the conversion price of the Series B Preferred Stock, the conversion price shall
be temporarily adjusted to the price at which such shares of common stock or
equity or debt securities convertible into or exercisable for shares of common
stock were issued for a period of ninety (90) calendar days. If we pay a
dividend or other distribution payable exclusively in common stock or pay or
make a dividend or other distribution, in whole or in part in common stock, on
any other class of capital stock, the conversion price shall be adjusted to that
price determined by multiplying the conversion price prior to the distribution
by a fraction (1) the numerator of which shall be the total number of shares of
common stock outstanding immediately prior to such dividend or other
distribution and (2) the denominator of which shall be the total number of
shares of common stock outstanding immediately after such dividend or other
distribution.

         Optional Conversion by us of the Series B Preferred Stock -- We may
elect to cause the Series B Preferred Stock to be converted into common stock:

         o    at any time after February 24, 1999, if the average of the daily
              closing sale price of the common stock for any twenty (20) trading
              days within a period of thirty (30) consecutive trading days has
              equaled or exceeded 160% of the conversion price; or

         o    at any time after February 23, 2002.

PUBLIC WARRANTS

         The following is a brief summary of certain provisions of the
redeemable common stock purchase warrants ("public warrants"). This summary does
not purport to be complete and is


                                       18
<PAGE>   21


qualified in all respects by reference to the actual text of the warrant
agreement among us, Continental Stock Transfer & Trust Co., and the public
warrant agent. As of March 31, 2000, there were 2,609,817 public warrants
outstanding.

         Exercise Price and Terms -- Each public warrant entitles the registered
holder thereof to purchase, at any time over a fifty-four (54) month period
commencing August 4, 1997, 1.074 shares of common stock at $4.19 per share,
subject to adjustment in accordance with the antidilution and other provisions
referred to below. The holder of any public warrant may exercise such public
warrant by surrendering the certificate representing the public warrant to the
public warrant agent, with the subscription form thereon properly completed and
executed, together with payment of the exercise price. The public warrants may
be exercised at any time in whole or in part at the applicable exercise price
until expiration of the public warrants. No fractional shares of common stock
will be issued upon the exercise of the public warrants.

         The exercise price of the public warrants bears no relationship to any
objective criteria of value and should in no event be regarded as an indication
of any future market price of the securities offered hereby.

         Adjustments -- The holders of the public warrants are protected against
dilution of their interests by adjustments, as set forth in the public warrant
agreement, of the exercise price and the number of shares of common stock
purchasable upon the exercise of the public warrants upon the occurrence of
certain events, including stock dividends, stock splits, combinations or
reclassification of the common stock, or sale by us of shares of our common
stock or other securities convertible into common stock at a price below the
then-applicable exercise price of the public warrants. Additionally, an
adjustment would be made in the case of a reclassification or exchange of common
stock, consolidation or merger of us with or into another corporation (other
than a consolidation or merger in which we are the surviving corporation) or
sale of all or substantially all of our assets in order to enable warrantholders
to acquire the kind and number of shares of stock or other securities or
property receivable in such event by holder of the number of shares of common
stock that might otherwise have been purchased upon the exercise of the public
warrant.

         Redemption Provisions -- Currently, all, but not less than all, of the
public warrants are subject to redemption at $0.10 per public warrant on not
less than thirty (30) days prior written notice to the holders of the public
warrants provided the per share closing price or bid quotation of the common
stock as reported on the Nasdaq equals or exceeds $6.75 (subject to adjustment)
for any twenty (20) trading days within a period of thirty (30) consecutive
trading days ending on the fifth trading day prior to the date on which we give
notice of redemption. The public warrants will be exercisable until the close of
business on the day immediately preceding the date fixed for redemption in such
notice. If any public warrant called for redemption is not exercised by such
time, it will cease to be exercisable and the holder will be entitled only to
the redemption price.

         Transfer, Exchange and Exercise -- The public warrants are in
registered form and may be presented to the public warrant agent for transfer,
exchange or exercise at any time on or prior to their expiration date on
February 4, 2002, at which time the public warrants become wholly


                                       19
<PAGE>   22


void and of no value. The holder may sell the public warrants instead of
exercising them. There can be no assurance, however, that a market for the
public warrants will continue.

         The public warrants are not exercisable unless, at the time of the
exercise, we have a current prospectus covering the shares of common stock
issuable upon exercise of the public warrants, and such shares of common stock
have been registered, qualified or deemed to be exempt under the securities laws
of the state of residence of the exercising holder of the public warrants.

         The public warrants were separately transferable immediately upon
issuance. Although the public warrants were not knowingly sold to purchasers in
jurisdictions in which the public warrants are not registered or otherwise
qualified for sale or exemption, purchasers may buy public warrants in the
after-market in, or may move to, jurisdictions in which public warrants and the
common stock underlying the public warrants are not so registered or qualified
or exempt. In this event, we would be unable lawfully to issue common stock to
those persons desiring to exercise their public warrants (and the public
warrants would not be exercisable by those persons) unless and until the public
warrants and the underlying common stock are registered, or qualified for sale
in jurisdictions in which such purchasers reside, or any exemption from
registration or qualification exists in such jurisdiction.

         Warrantholder Not a Stockholder -- The public warrants do not confer
upon holders any voting, dividend or other rights as stockholders.

         Modification of Public Warrants -- We and the public warrant agent may
make such modifications to the public warrants as we deem necessary and
desirable that do not adversely affect the interests of the warrantholders. We
may, in our sole discretion, lower the exercise price of the public warrants for
a period of not less than thirty (30) days on not less than thirty (30) days'
prior written notice to the warrantholders and Network 1 Financial Securities,
Inc., the representative of the underwriters for our initial public offering
(Network 1). Modification of the number of securities purchasable upon the
exercise of any public warrant, the exercise price and the expiration date with
respect to any public warrant requires the consent of two-thirds of the
warrantholders. No other modifications may be made to the public warrants,
without the consent of two-thirds of the warrantholders.


PRIVATE WARRANTS

         We have issued the private warrants in connection with certain
debentures and as compensation for services rendered by various consultants and
a financial consulting firm controlled by a former officer, director, and
stockholder of ViewCast.

         At March 31, 2000, 2,161,772 private warrants at exercise prices
ranging from $3.00 to $4.50 per share were exercisable into 2,270,305 shares of
common stock.


                                       20
<PAGE>   23


         In addition, at March 31, 2000, Network 1 and assigns held warrants to
purchase 140,000 units at $6.44 per unit, each unit consisting of one share of
common stock and one warrant to purchase 1.074 shares at an exercise price of
$4.50 through February 2002.


DELAWARE LAW WITH RESPECT TO BUSINESS COMBINATIONS

         As of the date of this Offering Circular, we are subject to the State
of Delaware's "business combination" statute, Section 203 of the Delaware
General Corporation Law. In general, such statute prohibits a publicly held
Delaware corporation from engaging in a "business combination" with a person who
is an "interested stockholder" for a period of three (3) years after the date of
the transaction in which that person became an interested stockholder, unless
the business combination is approved in a prescribed manner. A "business
combination" includes a merger, asset sale or other transaction resulting in a
financial benefit to the interested stockholder. An "interested stockholder" is
a person who, together with affiliates, owns (or, within three (3) years prior
to the proposed business combination, did own) fifteen percent (15%) or more of
the Delaware corporation's voting stock. The statute could prohibit or delay
mergers or other takeover or change in control attempts with respect to us and,
accordingly, may discourage attempts to acquire us.


TRANSFER AGENT AND REGISTRAR

         The transfer agent and registrar for the Common Stock is Continental
Stock Transfer and Trust Company, 2 Broadway, New York, New York 10004.


REPORTS TO STOCKHOLDERS

         We furnish our stockholders with annual reports containing audited
financial statements and such other periodic reports as we may determine to be
appropriate or as may be required by law.

         We have registered our Common Stock and public warrants under the
provisions of Section 12(g) of the Securities Exchange Act of 1934, and we have
agreed that we will use our best efforts to continue to maintain such
registration for a minimum of five (5) years from February 4, 1997. Such
registration will require us to comply with periodic reporting, proxy
solicitation and certain other requirements of the Securities Exchange Act of
1934.

                SELLING SECURITYHOLDERS AND PLAN OF DISTRIBUTION


         ViewCast has filed a Registration Statement on Form S-3 registering
2,772,904 shares of common stock issuable upon conversion of Series B Preferred
Stock and upon exercise of warrants for offer and sale by persons who exercise
the warrants. ViewCast is also registering shares of common stock issued as
payment of dividends on the Series B Preferred Stock. ViewCast is paying all
expenses in connection with this offering. Registration of the common stock
issuable upon conversion of Series B Preferred Stock, upon exercise of the
warrants and upon registration of common shares issued as dividends on the
Series B Preferred Stock, permits the holders of the common stock to sell their
shares in the public secondary market from time to time after the date of this
prospectus. Other than H.T. Ardinger, Jr. and M. Douglas Adkins, Esq., none of
the persons offering stock beneficially owns 5% or more of ViewCast's
outstanding common stock.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS

Articles Seven and Ten of ViewCast's Certificate of Incorporation, contain the
following provisions with respect to indemnification of Directors and Officers:

         SEVENTH. The Corporation shall, to the fullest extent permitted by
Section 145 of the General Corporation Law of the State of Delaware, as the same
may be amended and supplemented, indemnify any and all persons whom it shall
have power to indemnify under said section from and against any and all of the
expenses, liabilities or other matters referred to in or covered by said
section, and the indemnification provided for herein shall not be deemed
exclusive of any other rights to which those indemnified may be entitled under
any By-Law, agreement, vote of stockholders or disinterested Directors or
otherwise, both as to action in his official capacity and as to action in
another capacity while holding such office, and shall continue as to a person
who has ceased to be director, officer, employee or agent and shall inure to the
benefit of the heirs, executors and administrators of such a person.

         TENTH. To the fullest extent permitted by Delaware General Corporation
Law, a director of the Corporation shall not be personally liable to the
Corporation or its stockholders for monetary damages for breach of fiduciary
duty as a director. Neither any amendment nor repeal of this Article, nor the
adopting of any provision of this Certificate of Incorporation inconsistent with
this Article shall eliminate or reduce the effect of this Article in respect of
any matter occurring, or any cause of action, suite or claim that, but for this
Article would accrue or arise, prior to such amendment, repeal or adoption of an
inconsistent provision.

Section 145 of the General Corporation Law of the State of Delaware contains
provisions entitling directors and officers of ViewCast to indemnification from
judgment, fines, amounts paid in settlement and reasonable expenses, including
attorney's fees, as the result of an action or proceeding in which they may be
involved by reason of being or having been a director or officer of ViewCast
provided said officers or directors acted in good faith.

         ViewCast has entered into indemnification agreements with Ms. Laurie L.
Latham and Messrs. H.T. Ardinger, Jr., Glenn A. Norem, Joseph W. Autem, George
C. Platt, David A. Dean, Frederick B. Cowen, David T. Stoner, Neal S. Page,

and Robert Bernardi which provide for the indemnification of said officers and
directors (former directors in the case of Messrs. Jobe, Johnson, Culp,
Sterling, Bernardi and Oakes) to the fullest extent allowable under the laws of
the State of Delaware.

ITEM 17. UNDERTAKINGS.

(a)      The undersigned Company hereby undertakes:

         (1)      To file, during any period in which offers or sales are being
                  made, a post-effective amendment to this Registration
                  Statement to: (i) Include any prospectus required by Section
                  10(a) (3) of the Securities Act; (ii) Reflect in the
                  prospectus any facts or events which, individually or
                  together, represent a fundamental change in the information in
                  the registration statement and, (iii) Include any additional
                  or changed material information on the plan of distribution.

         (2)      For determining liability under the Securities Act, treat each
                  post-effective amendment as a new registration statement of
                  the securities offered, and the Offering of the securities at
                  that time to be the initial bona fide offering.

         (3)      File a post-effective amendment to remove from registration
                  any of the securities that remain unsold at the end of the
                  offering.

(b)      Insofar as indemnification for liabilities arising under the Securities
         Act of 1933 (the "Securities Act") may be permitted to directors,
         officers and controlling persons of the small business issuer pursuant
         to the foregoing provisions, or otherwise, the small business issuer
         has been advised that in the opinion of the Securities and Exchange
         Commission such indemnification is against public policy as expressed
         in the Securities Act and is, therefore, unenforceable.

         In the event that a claim for indemnification against such liabilities
         (other than the payment by the registrant of expenses incurred or paid
         by a director, officer or controlling person of the registrant in the
         successful defense of any action, suit or proceeding) is asserted by
         such director, officer or controlling person in connection with the
         securities being registered, the registrant will, unless in the opinion
         of its counsel the matter has been settled by controlling precedent,
         submit to a court of appropriate jurisdiction the question whether such
         indemnification by it is against public policy as expressed in the
         Securities Act and will be governed by the final adjudication of such
         issue.

                         Re:     Registration Statement on Form S-3

Dear Sirs:

         We have acted as counsel for ViewCast.com, Inc., a Delaware corporation
(the "Company"), in connection with the filing of a registration statement on
Form S-3 under the Securities Act of 1933, as amended ("Registration Statement")
with respect to shares of its common stock, par value $0.01 per share, of which
2,646,896 shares are authorized but unissued shares which have been reserved for
issuance upon the exercise of warrants and upon conversion of Series B
Convertible Preferred Stock (the "Original Issue Shares") issued by the Company
and 126,008 shares have been issued as payment for dividends on the Series B
Convertible Preferred Stock (the "Outstanding Shares").

         We have examined originals or copies, certified or otherwise
identified, of such documents, corporate records and other instruments as we
have deemed necessary or advisable for purposes of this opinion. As to matters
of fact, we have examined and relied upon the warrants described above and,
where we have deemed appropriate, representations or certificates of officers of
the Company or public officials. We have assumed the authenticity of all
documents submitted to us as originals, the genuineness of all signatures, the
legal capacity of natural persons and the conformity to the originals of all
documents submitted to us as copies.

         Based on the foregoing, we are of the opinion that (i) the Original
Issue Shares that are being registered pursuant to the Registration Statement
have been duly authorized and, when issued and paid for in accordance with the
terms of the warrants, the Original Issue Shares will be validly issued, fully
paid and non-assessable and (ii) the Outstanding Shares that are being
registered pursuant to the Registration Statement have been duly authorized and
are validly issued, fully paid and non-assessable.

         In rendering the opinion set forth above, we have not passed upon and
do not purport to pass upon the application of "doing business" or securities or
"blue-sky" laws of any jurisdiction (except federal securities laws).

         This opinion is given solely for the benefit of the Company and
purchasers of shares pursuant to exercise of the warrants, and no other person
or entity is entitled to rely hereon without express written consent.

         We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the references to our Firm's name therein.


                                                  Very truly yours,
