                                  RISK FACTORS

     An investment in the common stock involves a high degree of risk. You
should carefully consider the risks described below and the other information
contained in this prospectus before deciding to invest in our common stock. The
risks described below are not the only ones facing our company. Additional risks
not presently known to us or which we currently consider immaterial may also
adversely affect our company. If any of the following risks actually occur, our
business, financial condition and operating results could be materially
adversely affected. In such case, the trading price of our common stock could
decline, and you could lose a part or all of your investment.

Substantial Dependence on Be There! Products Whose Market Acceptance is Not
Proven

     Our goal of returning to profitability and developing a more reliable
revenue base will depend on the success of our Be There! Remote Access System.
Since its release in early 1997, the Be There! product line has had very limited
success and revenue to date from the products has not been significant. The Be
There! system represents a new type of product for us which is significantly
different from the our network multiplexer products and custom modem products.
This new product 


                                       3

 
line presents a unique set of risks and challenges for us. Our future success is
dependent on many factors, including our ability to do the following:

     .    penetrate our target markets and increase sales of the Be There!
          products;

     .    timely and successfully develop and introduce new or follow-on
          products;

     .    enhance the features and performance, including voice quality, in
          order to achieve broad market acceptance of the Be There! products;

     .    continue to develop existing distribution channels and establish new
          distribution channels;

     .    develop affiliations with leading market participants which facilitate
          product development and distribution;

     .    market existing and new products through distributors, resellers and
          others; and

     .    overcome potential competition.

     In order to pursue our objectives in the remote access solutions market, we
have developed and continue to seek relationships with strategic partners who
can assist us with marketing, distribution and further development of the Be
There! product line, who can provide needed capital, and who can enhance the
value of our business and assets. We can not assure you that we will be able to
maintain existing relationships or develop new ones. The loss of these
relationships or the inability to forge a key relationship could materially
adversely affect us. We can not assure you that we will establish a market for
Be There! or establish our credibility in such market.

Recent Operating Losses and Expected Continued Losses

     We have suffered substantial recurring losses, and we have not had
significant revenue to date from our Be There! products. It is possible that we
will never return to profitability or generate future revenue levels sufficient
to support operations. Our independent auditors have included an explanatory
paragraph in their report covering the June 30, 1998 financial statements which
expresses substantial doubt about our ability to continue as a going concern.
The explanatory paragraph notes that we have suffered recurring losses and
incurred negative cash flow from operations during fiscal 1998 and fiscal 1997.

Need for Additional Capital and No Assurance of Raising Additional Capital

     Our ability to sustain operations, make future capital expenditures and
fund the development and marketing of new or enhanced products is highly
dependent on our ability to raise additional capital. We do not expect that our
limited existing cash will sustain the company until we achieve positive cash
flow and we do not expect to return to profitability so long as expenditures on
the Be There! products remain disproportionate to attendant Be There! revenues.
Even if our sales grow, we could require additional capital to hire additional
personnel and increase inventory levels. We will therefore likely require more
capital in the near future. We can not predict the timing and amount of our
future capital requirements. It is possible that sources of capital, such as
investors, lenders or strategic partners may perceive our recent history of
losses, current financial condition, or lack of our technology's acceptance as
too great a risk to bear. As a result, we may not be able to obtain additional
capital on favorable terms, if at all. If we can not obtain additional capital
when needed, 


                                       4

 
we may be forced to agree to terms which are not attractive to the company or
our shareholders or we may be required to suspend some, or ultimately, all of
our operations.

Risk of Losing Nasdaq National Market Listing

     Companies with securities listed on the Nasdaq National Market must satisfy
certain maintenance criteria, including minimum net tangible asset and stock
price requirements in order to remain listed. Our recurring losses have had a
negative effect on shareholders' equity, and we did not meet the Nasdaq National
Market net tangible assets requirement of $4 million on June 30 and September
30, 1998. In late September 1998, we received a notice of non-compliance from
Nasdaq. We appealed the determination and a hearing on our appeal was held in
mid-January 1999. We have not yet received the results of the hearing, and can
give no assurance as to the outcome. In addition, our stock price is volatile
and, during a six-week period in 1998, closed below the Nasdaq National Market
minimum requirement of $1.00 per share. We may not be able to sustain compliance
with the maintenance criteria of the Nasdaq National Market, the failure of
which could result in the delisting of our common stock from such market.
Termination of listing of the common stock would likely have a material adverse
effect on the market price and liquidity of the common stock, and on our ability
to raise additional capital. Delisting could also jeopardize certain secondary
trading exemptions from state "blue sky" laws, further affecting liquidity of
the common stock. In addition, we would be liable for substantial monetary
penalties to the holders of the preferred stock in the event of such a
termination of listing. Our failure to pay such penalties could also result in
redemption of the preferred stock.

Potential Adverse Effects of Rapid Technological Changes

     The market for our products is characterized by rapidly changing
technology, emerging industry standards, product proliferation and short product
life cycles. We believe that our future success will depend on our ability to
enhance our existing products and to develop and introduce new products, which
conform to or support emerging data communications standards, meet a wide range
of evolving user needs, and be accepted by the market. The introduction of new
or enhanced products requires us to manage the transition from older products in
order to minimize disruption in customer ordering patterns, avoid excessive
levels of older product inventories, and ensure that adequate supplies of new
products can be delivered to meet customer demand. We may not succeed in
developing and marketing such new products or that we will be able to respond
effectively to technological changes, emerging industry standards, or new
product introductions by others. In addition, our competitors may introduce
products or services incorporating technology as advanced or more advanced than
ours, making our products or technologies obsolete. As the technical complexity
of new products increases, it may become increasingly difficult to introduce new
products quickly and according to schedule. Delays in developing or shipping new
or enhanced products, as we have experienced in the past, could adversely affect
our operating results. Conversely, the growth of the market for communications
products has been driven in part by the rapid technological change experienced
by that market. It is possible that such rapid technological change will not
continue or that the telecommunications infrastructure will not have the
capacity to support such products. Any of these factors could adversely affect
the market for our products as well as our operating results.


                                       5

 
Teleworker Market May Not Develop as Expected

     The teleworker market is rapidly changing. The size and growth of the
teleworker market may be affected by various factors, including changes in
market trends and market needs and changes in technology. The actual rate of
growth and size of the market may not reach expected levels. In addition, our
teleworker products have not yet been accepted widely in the market and may
never be adequately accepted in the market, whether because of shortcomings with
our feature sets and performance or for other reasons. We are beginning to see
and expect to see a growing array of remote access solutions, some or many of
which may be competitive to our products. Our business will be adversely
affected if the teleworker market does not develop as we hope, or if we are not
able to penetrate this market.

Intensely Competitive Industry; Competitors Have Greater Resources

     The communications industry is intensely competitive. We currently compete
principally in the remote access markets. Our existing and potential competitors
have far more extensive financial, engineering, product development,
manufacturing and marketing resources than we have. As a result, these
competitors may be able to respond more quickly to new or emerging technologies
and changes in customer requirements, or to devote much greater resources to the
development, promotion, and sale of their products and services than we can. In
addition, current and potential competitors have established or may establish
cooperative relationships among themselves or with third parties to address the
needs of our prospective customers. New competitors or alliances among
competitors may emerge and rapidly acquire significant market share. Many of
these competitors have far greater brand recognition, which places us at a
competitive disadvantage. In addition, some competitors, including many foreign
competitors, have a lower cost structure that gives them a competitive advantage
on the basis of price. Our products and services compete on the basis of a
number of factors, including features and functions, modularity and
expandability, reliability, service and support, supplier credibility,
recommendations of the systems integrators, perceived cost savings and price.

     Our teleworker products may compete in areas in which we do not have the
experience or resources to address. Competitors may introduce products or
services incorporating technology as advanced or more advanced than ours.
Changes in the communications environment may also render our competitors'
product solutions more attractive to the customer than ours. For example, Sprint
recently announced its ION service and Lucent Technologies has also announced a
relevant product known as the Virtual Telephone, both of which purport to
provide many of the Be There! features. Technologies such as ISDN and the more
recently announced DSL products also provide a more limited set of features
similar to those offered by Be There! In addition, we expect new competition to
arise as new technologies develop, such as Computer Telephony Integration, Voice
Over IP, and others. The competitive pressures we face could materially and
adversely affect our business, financial condition or operating results.

Difficulties in Marketing Through Indirect Sales Channels

     We believe that the success of our Be There! products will depend, in large
part, on our ability to market through distributors, resellers, and other
strategic marketing partners. We have little experience marketing in these
channels. Independent distributors, resellers, and other strategic marketing
partners, including Inacom Communications and Data General Corp., are not
contractually committed to continue to purchase our products and therefore could
discontinue carrying our 


                                       6

 
products at any time in favor of a competitor's products or for any other
reason. The loss of any of our major distributors or resellers, including Inacom
Communications and Data General Corp., would likely have a significant adverse
effect on our business. Our failure to successfully develop, manufacture, and
market products appropriate for such channels could also have a material adverse
effect on our business.

Dependence on Limited Number of Customers; Fluctuations in Period to Period
Operating Results

     Although we have not yet recorded significant revenue from our teleworker
products, we are currently attempting to market our products to large
corporations, as well as to smaller businesses. Although we have not had much
success to date, if we do succeed in attracting large customers, our revenue
could fluctuate significantly. We have also recently announced orders from
Sabratek corporation, a manufacturer of medical systems for the alternate-site
health care market, and announced our expectation for additional orders over the
coming months. Sabratek is not obligated to purchase a minimum amount of
products. A reduction or delay in orders or a delay or default in payment by an
important customer, including Sabratek, or the loss of a major customer, could
materially and adversely affect our operating results. Other factors which could
cause operating results for a particular quarter or other period to vary
considerably include the following:

     .    the overall state of the communications products and services market;

     .    pricing and other competitive conditions;
  
     .    market acceptance of our products;

     .    the timing of the announcement and introduction of new products and
          services by us and our competitors;

     .    variations in our product mix and component costs;

     .    the financial stability of our customers;

     .    the timing of our expenditures in anticipation of future sales;

     .    the timing of product development costs; and

     .    economic conditions generally.

     We expect our operating results to continue to fluctuate from period to
period in the future as a result of the factors described above and other
factors, particularly until such time, if ever, that revenue from Be There!
sales increase substantially. Any of these factors could materially adversely
affect our operating results.

Dependence on Management and Other Key Employees

     Our success is dependent upon our ability to retain and continue to attract
highly talented managerial and technical personnel. We are especially dependent
on our president and chief executive officer, our other senior officers, and our
teleworker products sales executives to increase revenue from Be There!
products, and on our key technical personnel to introduce new products and to
remain in the forefront of technological advances. All of our senior executives
and other employees are employed on an "at-will" basis. We do not have any
insurance on our employees other than the $1 million dollar key-man insurance

Dr. W. B. Barker. Competition for qualified personnel is intense in our industry
and we may not be able to retain our key employees or attract and assimilate
other qualified personnel. The loss of key personnel could materially and
adversely affect our business.

Dependence on Third Party Suppliers

     We manufacture our products using components or subassemblies bought from
third party suppliers. Some of these components, such as critical microchips,
are available only from a single supplier, and others are available only from a
limited number of suppliers. Much of our prior sales have been from products
containing one or more components which are available from single supply
sources. We do not have any guaranteed supply arrangements. In addition,
component supplies are affected by worldwide conditions in the semiconductor
market. If we could not obtain a sufficient supply of such components from
current sources, we could have trouble obtaining alternative sources or altering
product designs to use alternative components. We have experienced and may again
experience supply shortages which delay product shipments. We may also have
trouble controlling the quality and reliability of the components we use to
manufacture our products. The costs of components can also rise quickly and
without warning. The occurrence of any of these events could adversely affect
our business, customer relationships or operating results.

Dependence on Others for Manufacturing Services

     We use third party manufacturers to assist us in assembling our products.
Because of this reliance on third party manufacturers, we can not always
exercise direct control over manufacturing quality and costs. We may also have
problems with production schedules of our products because of other demands
placed on the third party manufacturers. Delays in production or deficiencies in
quality could adversely affect our operating results and could damage customer
relationships. These factors could also result in significantly higher
manufacturing costs.

Difficulties in Managing Inventory

     In the past we have substantially increased our inventory levels to meet
production requirements of existing or anticipated orders. Inventory levels have
also increased because of delays in receiving certain components, such as
critical chipsets, from suppliers and the concurrent accumulation of other
inventory. Increased levels of inventory could adversely affect our liquidity or
increase the risk of inventory obsolescence, whether from cancellation of
orders, failure to receive anticipated orders or for other reasons. High levels
of inventory could also increase the risk of a decline in market value of such
inventory or the risk of inventory losses from theft, fire, or other similar
occurrences. Our business and financial condition could be materially adversely
affected if we do not effectively manage our purchasing activities and inventory
levels.

Reliance on Patents and Proprietary Technology

     Our success depends in part on our technological expertise and proprietary
product designs. We rely on our trade secret protection efforts and, to a lesser
extent, on patents and copyrights to protect our proprietary technologies. These
steps may not be adequate to deter misappropriation or infringement of our
proprietary technologies. Competitors may also independently develop
technologies that are similar or superior to our technology. In addition, the
laws of some foreign countries do not protect proprietary rights to the same
extent as do the laws of the United States. 

                                       8

 
Intellectual property laws of the United States and foreign countries may not be
adequate to protect our proprietary rights.

     We expect that remote access technologies and know-how in general will
become increasingly valuable intellectual properties as competition intensifies.
We believe this increasing value may produce a competitive environment where
intellectual property disputes are likely to arise. Intellectual property
disputes may be initiated against us for tactical purposes to gain competitive
advantage or overcome competitive disadvantage, even if the merits of a specific
dispute are doubtful. In some cases, we grant or may grant licenses of our
intellectual property rights. We may be required to bring or defend against
litigation to enforce our patents, to protect our trademarks, trade secrets, and
other intellectual property rights, to defend against infringement claims, to
resolve disputes under technology license arrangements, and to determine the
scope and validity of our proprietary rights or those of others. See "Patent
Infringement Lawsuit" below. Any litigation could be costly and divert
management's attention, each of which could have a material adverse effect on
our business and financial condition. Our limited resources may limit our
ability to bring or defend against any such litigation. Adverse determinations
in litigation, including litigation we initiate, could result in the loss of our
proprietary rights, subject us to significant liabilities, require us to seek
licenses from third parties or prevent us from manufacturing or selling our
products. Any of these results could materially adversely affect our business,
financial condition and operating results.

     We currently license some of the technologies which we use in our products.
We may not be able to continue to obtain such licenses on commercially
reasonable terms. In addition, infringement claims against our suppliers could
adversely affect our ability to purchase components from those suppliers.

Patent Infringement Lawsuit

     On August 19, 1998, we sued Lucent Technologies, Inc. in United States
District Court in San Antonio, Texas. The suit alleges that Lucent is infringing
on our patent entitled "System and Method for Providing a Remote User with a
Virtual Presence to an Office." Although we believe our claims against Lucent
are valid and we intend to vigorously pursue such claims, we may not be able to
fully pursue the lawsuit or defend against possible counterclaims because of
limited resources, including our ability to pay legal expenses. In addition, the
lawsuit could adversely affect the validity or enforceability of our patents.
Litigation by its very nature is unpredictable. We may not prevail in the
lawsuit. Our failure to prevail in a significant manner may materially adversely
affect our financial condition and operations. Additional risks associated with
such litigation are also described in the risk factor above regarding
intellectual property rights.

Compliance with FCC and Other Regulatory Standards

     Aspects of our products are regulated by the Federal Communications
Commission. Our products must typically be tested before they are sold. The
failure of our products to conform to FCC regulations or meet FCC testing
requirements could delay the introduction of our products into the market, and
could adversely affect our business. Foreign authorities often establish
telecommunications standards different from those in the United States, making
it difficult and more time consuming to obtain the required regulatory
approvals. A significant delay in obtaining such regulatory approvals could
adversely affect our operating results. Changes in such laws, policies, or
requirements could also affect the demand for our products or result in the need
to modify products, either of which could involve substantial costs or delays in
sales and adversely affect our operating results.

We Could Be Required to Redeem the Outstanding Preferred Stock

     A total of 2,500 shares of Series D, E and F Convertible Preferred Stock
are outstanding, with a total stated value of $2,500,000. The holders of the
outstanding preferred stock have the right to require us to redeem their shares
of preferred stock for cash, at 120% of stated value, if any of the following
happens:

     .    our board agrees to sell the company or the Be There! product line to
          another company, or our board consents to the tender offer of our
          shares by another company;

     .    this registration statement is not declared effective by the SEC
          before May 16, 1999;

     .    this registration statement can not be used to permit the sale of the
          shares issuable upon conversion of the preferred stock for 30
          consecutive trading days;

     .    we voluntarily terminate the listing of our shares on the Nasdaq
          National Market;

     .    we fail to deliver shares of common stock upon conversion of the
          preferred stock; or

     .    we file for bankruptcy.

     In addition, if our common stock is delisted from the Nasdaq National
Market, and we fail to pay required penalties to the holders of the preferred
stock, then the holders of the preferred stock can require us to redeem their
shares of preferred stock. If we are required to redeem the preferred stock for
any reason, it is not likely that we would have sufficient cash available to
effect the redemption. In that case we would be forced to attempt to find other
sources of financing. If we could find such financing at all, it is not likely
that that such financing would be on favorable terms. The inability to find
financing or the terms of such unfavorable financing and our resulting lack of
liquidity could force us to close portions or all of our operations.

Potential Drop in Stock Price Due to Floating Conversion Feature of Series D
Convertible Preferred Stock

     The Series D Convertible Preferred Stock is convertible into common stock
at a conversion price equal to a discount from the market price on the date of
conversion. On March 16, 1999, a conversion price floor and ceiling will be
established based on average market prices of the common stock during specified
periods of time prior to March 16, 1999. The conversion price is capped at $3.00
per share. Based on this conversion price formula, as the market price of the
common stock declines, the Series D Convertible Preferred Stock will be
convertible into a proportionately greater number of shares of common stock,
until the conversion price floor is reached. The number of shares we issue in
payment of the premium on the preferred stock will also increase as the market
price of the common stock declines. These increases in the number of shares
issuable upon conversion of the Series D Convertible Preferred Stock and upon
payment of the premium on the preferred stock could result in a meaningful
dilution to other holders of common stock and adversely affect the market price
of the common stock. In addition, the holders of the Series D Convertible
Preferred Stock could convert and sell part of their shares, which could drive
the stock price down even further and permit them to convert additional shares
at a lower price.

Future Sales of Shares Could be Dilutive and Impair Ability to Raise Capital

     This prospectus covers the potential sale from time to time of up to
3,688,778 shares of common stock. At January 20, 1999, we had reserved
approximately 1,284,899 shares of common stock for issuance upon conversion of
the outstanding Series E Convertible Preferred Stock and upon exercise of other
outstanding warrants. Those reserved shares are covered by other registration
statements and can be sold from time to time after issuance. At January 20,
1999, we had also reserved approximately 2,435,768 shares of common stock for
issuance under currently approved employee benefit plans, including 1,531,260
shares subject to outstanding options. The sale or availability for sale of a
significant number of shares of common stock in the public market could
adversely affect the market price of the common stock and impair our ability to
raise further capital. In addition, several persons have rights of first refusal
on additional financings. The existence of such rights could also adversely
affect our ability to complete future financings.

Possible Negative Effects of Anti-Takeover Measures

     We have adopted a shareholder rights plan in an effort to guard against
abusive tactics which could deprive our shareholders of the opportunity to
realize the long-term value of their investment. In addition, certain provisions
of our articles of incorporation may have the effect of discouraging unsolicited
proposals to acquire control over us. Our board of directors can, without
obtaining shareholder approval, issue shares of preferred stock having rights
that could adversely affect the voting power of holders of the common stock,
including the right to vote as a class on any proposed change of control. Such
an issuance could have the effect of delaying, deferring, or preventing a change
of control of the company and might make it difficult to replace incumbent
management.

     Certain provisions of Texas corporate law, including the Texas Business
Combination Law, could also have the effect of hindering or delaying a takeover
bid for the company. Such provisions may inhibit takeover bids and decrease the
chance of shareholders realizing a premium to the then market price of the
common stock as a result of a takeover bid. In general, the Business Combination
Law prohibits a Texas "issuing public corporation" from engaging in a "business
combination" with an "affiliated shareholder," or an affiliate or associate
thereof, for a period of three years after the date of the transaction in which
the person became an affiliate shareholder, unless the business combination is
approved in a prescribed manner. "Business Combinations" include mergers, asset
sales and other transactions resulting in a financial benefit to the affiliated
shareholder. An "affiliated shareholder" is a person who, together with
affiliates and associates, owns or did own 20% or more of the corporation's
voting stock. The terms appearing in quotations are defined in the Texas
Business Combination Law.

Price Volatility

     The market price of our common stock has been, and will likely continue to
be, highly volatile. This is caused in part by our relatively small market float
(the aggregate market value of our publicly traded shares). Events or
circumstances may cause a much greater percentage change in the market price of
our shares than the market price of a company with a large market float. Many of
the events or circumstances are beyond our control. Factors which may cause the
market price of our stock to fluctuate substantially include the following:

                                       11

 
     .    quarterly fluctuations in our operating results;

     .    changes in and terminations of our distributor or reseller 
          relationships;

     .    adverse circumstances affecting the introduction or market acceptance
          of new products which we may offer;

     .    changes in or cancellations under existing contracts;

     .    loss of key personnel;

     .    changes in the market success of other companies' products which
          utilize or incorporate our products;

     .    announcements of new products by our competitors;

     .    changes in, or failure to meet, financial estimates by securities
          analysts;

     .    changes in accounting principles;

     .    sales by our existing shareholders, including sales of the shares
          covered by this prospectus; and

     .    short selling.


     In addition, stock prices for many technology companies fluctuate widely
for other reasons unrelated to our operating results. For example, changes in
the general market perception of the high technology industry can affect our
stock price. These fluctuations, as well as general economic, political and
market conditions, such as recessions or military conflicts, may adversely
affect the market price of our common stock. Changes in the market price of our
common stock could affect our ability to successfully attract and retain
qualified personnel, develop distributor, customer or strategic partner
relationships, or complete other transactions in the future. In the past,
following periods of volatility in the market price of a company's securities,
securities class action litigation has often been instituted against companies
with fluctuating stock prices. Such litigation could result in substantial costs
and a diversion of management's attention and resources, having a material
adverse effect on us.

Year 2000 Risks

     As is true for most companies, the year 2000 issue creates a risk for us.
If computer systems do not correctly recognize date information when the year
changes to 2000, there could be an adverse impact on our operations. The risk
for us exists primarily in the following areas:

     .    disruption of computer systems used by us to run our business
     including information systems, equipment and facilities;

     .    disruption of computer systems used by our suppliers, including
     suppliers of component parts and manufacturing services, as well as
     suppliers of our necessary energy, telecommunications and transportation
     needs;

     .    potential warranty or other claims from our customers based on year
     2000 problems with our products; and

                                       12

 
     .    potential for reduced spending by other companies on our products as a
     result of significant information systems spending on year 2000 compliance.

     We are continuing to evaluate and mitigate our exposure in these areas
where appropriate and expect to establish contingency plans for identifiable
risks by June 30, 1999. We can not be certain that unexpected year 2000
compliance problems of our products, or our computer systems or of our vendors,
customers and service providers, will not materially and adversely affect our
business, financial condition or operating results.


                           FORWARD-LOOKING STATEMENTS

     This prospectus and the documents incorporated by reference into this
prospectus contain forward-looking statements that are based on current
expectations, estimates and projections about our industry, management's
beliefs, and assumptions made by management. Words such as "anticipates,"
"expects," "intends," "plans," "believes," "seeks," "estimates," and variations
of such words and similar expressions are intended to identify such
forward-looking statements. These statements are not guarantees of future
performance and are subject to certain risks, uncertainties and assumptions that
are difficult to predict; therefore, actual results may differ materially from
those expressed or forecasted in any forward-looking statements. Such risks and
uncertainties include those noted in "Risk Factors" above and in the documents
incorporated by reference. We undertake no obligation to update publicly any
forward-looking statements, whether as a result of new information, future
events or otherwise.

                                 USE OF PROCEEDS

     We will not receive any proceeds from the sale by the selling shareholders
of the shares of common stock covered by this prospectus.

                              SELLING SHAREHOLDERS

     The following table lists the names of the selling shareholders, the number
of shares of common stock beneficially owned by each selling shareholder on
January 22, 1999, and the number of shares which may be offered for sale by this
prospectus. Each selling shareholder provided to us the information regarding
his or its share ownership. Because the selling shareholders may offer all, some
or none of their common stock, we can not provide a definitive estimate as to
the number of shares that will be held by the selling shareholders after the
offering and we prepared the following table based on the assumption that the
selling shareholders sell all of the shares of common stock covered by this
prospectus. The number of shares shown in the following table as being offered
by the selling shareholders upon conversion of their preferred stock or exercise
of their warrants does not include such presently indeterminate number of shares
of common stock as may be issuable upon conversion and exercise of those
securities pursuant to applicable antidilution provisions.

     Convertible Preferred Stock and Class A Warrants for 151,019 shares of
     common stock as part of a second closing under a purchase agreement dated
     July 24, 1998. This prospectus covers the resale of the shares of common
     stock issuable upon conversion and exercise of those securities. The number
     of shares shown as beneficially owned assumes (i) the conversion on 

                                       14

     Convertible Preferred Stock and Class B Warrants for 140,625 shares of
     common stock as part of the third closing under the purchase agreement
     dated July 24, 1998. This prospectus covers the resale of the shares of

     E Convertible Preferred Stock issued on July 24, 1998, in the first closing
     under the purchase agreement, at the conversion price of $1.00, into
     750,000 shares of common stock (exclusive of any shares in payment of the
     premium on the preferred stock) and (ii) the exercise of Class B Warrants
     issued in the first closing under the purchase agreement, for 140,625
     shares of common stock. The securities issued in the first and third
     closings under the purchase agreement are not convertible or exercisable,
     except in limited circumstances, until the first anniversary of their dates
     of issuance. The number of shares shown as beneficially owned does not
     include shares of common stock beneficially owned by Jeffrey P. Blanchard,
     a member of the general partner (a limited liability company) of the
     general partner (a limited partnership) of the selling shareholder. The
     selling shareholder disclaims any beneficial ownership in Mr. Blanchard's
     shares. Mr. Blanchard is the chairman of our board of directors. The number
     of shares being offered has been determined by agreement and 

                                       15

 
     includes 150% of the number of shares of common stock issuable upon
     conversion of the Series F Convertible Preferred Stock at conversion price
     of $3.43125.

(5)  On December 17, 1998, as compensation for services in connection with the
     purchase agreement, the selling shareholder received Class A Warrants to
     purchase 148,683 shares of common stock. This prospectus covers the resale
     of the shares of common stock issuable upon exercise of those warrants. The
     number of shares shown as beneficially owned also includes 279,623 shares
     of common stock issuable upon exercise of additional warrants.

(6)  On December 17, 1998, as compensation for services in connection with the

(12) The Series D Convertible Preferred Stock is convertible into common stock
     at the option of the holder beginning March 17, 1999, subject to
     acceleration in certain events, at a conversion price equal to 80% of the
     trailing five-day average closing bid price of the common stock on the
     conversion date. The conversion price is subject to a minimum conversion
     price equal to the trailing 15-day average closing bid price of the common
     stock on March 17, 1999 and is subject to the maximum conversion price
     equal to the lesser of $3.00 or the trailing five-day average closing bid
     price of the common stock on March 17, 1999. The number of shares of common
     stock issuable upon conversion of one share of Series D Convertible
     Preferred Stock is computed by dividing the share's stated value of $1,000
     by the applicable conversion price, plus, in the event we elect to pay in
     common stock the 8% accrued premium on such preferred stock, that number of
     shares of common stock having a value equal to such accrued premium. For a
     complete description of the rights, preferences and restrictions of the
     Series D Convertible Preferred Stock, see the Statement of Designation,
     Preferences and Rights of Series D Convertible Preferred Stock filed as an
     exhibit to our Current Report on Form 8-K filed on August 4, 1998.

(13) The Series F Convertible Preferred Stock is convertible into common stock
     at the option of the holder beginning January 22, 2000, subject to
     acceleration in certain events, at a conversion price of $3.43125. The
     conversion price was determined pursuant to the purchase agreement dated
     July 24, 1998, and equals the trailing five-day average closing bid price
     on January 7, 1999, the date we issued the notice under the purchase
     agreement to call the additional investment. The number of shares of common
     stock issuable upon conversion of one share of Series F Convertible
     Preferred Stock is computed by dividing the share's stated value of $1,000
     by the applicable conversion price, plus, in the event we elect to pay in
     common stock the 8% accrued premium on such preferred stock, that number of
     shares of common stock having a value equal to such accrued premium. For a
     complete description of the rights, preferences and restrictions of the
     Series F Convertible Preferred Stock, see the Statement of Designation,
     Preferences and Rights of the Series F Convertible Preferred Stock, filed
     as an exhibit to this registration statement.


                              PLAN OF DISTRIBUTION

     The shares of common stock may be sold or distributed from time to time by
the selling shareholders, or by pledgees, donees or transferees of, or other
successors in interest to, the selling shareholders, directly to one or more
purchasers (including pledgees) or through brokers, dealers or underwriters who
may act solely as agents or may acquire shares of common stock as principals, at
market prices prevailing at the time of sale, at prices related to such
prevailing market prices, at negotiated prices, or at fixed prices, which may be
changed. The distribution of the shares of common stock may be effected by one
or more of the following methods:

 .    ordinary brokers' transactions, which may include long or short sales;

                                       17

 
 . transactions involving cross or block trades or otherwise on any national
  securities exchange or quotation service on which the common stock may be
  listed or quoted at the time of sale, in the over-the-counter market or in
  any other market for the common stock;
  
 . purchases by brokers, dealers or underwriters as principals and resale by
  such purchasers for their own accounts pursuant to this prospectus;
  
 . "at the market" to or through market makers or into an existing market for
  the common stock;
  
 . in other ways not involving market makers or established trading markets,
  including direct sales to purchasers or sales effected through agents;
  
 . through transactions in options, swaps or other derivatives (whether
  exchange-listed or otherwise); or
  
 . any combination of the foregoing, or by any other legally available means.

     In addition, the selling shareholders or their successors in interest may
enter into hedging transactions with broker-dealers who may engage in short
sales of common stock in the course of hedging the positions they assume with
the selling shareholders. The selling shareholders or their successors in
interest may also enter into option or other transactions with broker-dealers
that require the delivery to such broker-dealers of the shares of common stock,
which shares may be resold thereafter pursuant to this prospectus. Shares of
common stock to be sold hereunder may be issued upon conversion of the preferred
stock and exercise of the warrants in accordance with their respective terms, or
in other transactions with us involving the preferred stock or warrants,
including, without limitation, issuance of shares of common stock in exchange
for shares of preferred stock or warrants and issuance of shares of common stock
pursuant to modification of the terms of the preferred stock or warrants, or in
settlement of claims with respect to rights of holders of preferred stock or
warrants.

     Brokers, dealers, underwriters or agents participating in the distribution
of the shares of common stock as agent may receive compensation in the form of
discounts, concessions or commissions from the selling shareholders (and, if
they act as agent for the purchaser of such shares of common stock, from such
purchaser). Such discounts, concessions or commissions as to a particular
broker, dealer, underwriter or agent might be greater or less than those
customary in the type of transaction involved.

     The selling shareholders and any brokers, dealers, underwriters or agents
that participate in the distribution of the shares of common stock may be deemed
to be "underwriters" within the meaning of the Securities Act, and any
discounts, commissions or concessions received by any such persons might be
deemed to be underwriting discounts and commissions under the Securities Act.
Neither we nor the selling shareholders can presently estimate the amount of
such compensation. We know of no existing arrangements between any selling
shareholder and any other Shareholder, broker, dealer, underwriter or agent
relating to the sale or distribution of the shares of common stock.

     Any underwriter may engage in stabilizing transactions in accordance with
Rule 104 under the Exchange Act. Rule 104 permits stabilizing bids to purchase
the underlying security so long as the stabilizing bids do not exceed a
specified maximum. The underwriters may over-allot shares of the common stock in
connection with an offering of the common stock, thereby creating a short

                                       18

 
position in the underwriters' account. These transactions, if commenced, may be
discontinued at any time.

     To the extent required, we will file, during any period in which offers or
sales are being made, a supplement to this prospectus which sets forth, with
respect to a particular offering, the specific number of shares of common stock
to be sold, the name of the selling shareholder, the sales price, the name of
any participating broker, dealer, underwriter or agent, any applicable
commission or discount and any other material information with respect to the
plan of distribution not previously disclosed.

     We will not receive any of the proceeds from the sale of the shares of
common stock offered hereby. We will pay substantially all of the expenses
incident to this offering of the shares of common stock by the selling
shareholders to the public other than commissions and discounts of brokers,
dealers, underwriters or agents. Such expenses are currently estimated to be
approximately $70,000. We have agreed to indemnify the selling shareholders and
certain related persons against certain liabilities, including certain
liabilities under the Securities Act.

     In order to comply with certain states' securities laws, if applicable, the
shares of common stock will be sold in such jurisdictions only through
registered or licensed brokers or dealers. In addition, in certain states the
common stock may not be sold unless the common stock has been registered or
qualified for sale in such state or an exemption from registration or
qualification is available and is satisfied.


                                 LEGAL OPINIONS

     Our outside law firm, Akin, Gump, Strauss, Hauer, & Feld, L.L.P., San

                                     EXPERTS

     Our financial statements as of June 30, 1998 and 1997, and for each of the
years in the three year period ended June 30, 1998, have been incorporated by
reference in this prospectus and in the registration statement of which this
prospectus forms a part in reliance upon the report of KPMG LLP, independent
certified public accountants, incorporated by reference herein, and upon the
authority of said firm as experts in accounting and auditing.

     The report of KPMG LLP contains an explanatory paragraph that states that
we have suffered recurring losses and incurred negative cash flow from
operations, which conditions raise substantial doubt about our ability to
continue as a going concern. The financial statements do not include any
adjustments that might result from the outcome of that uncertainty.

Item 15.  Indemnification of Directors and Officers.

     Article 2.02-1 of the Texas Business Corporation Act provides for
indemnification of directors and officers in certain circumstances. In addition,
the Texas Miscellaneous Corporation Law provides that a corporation may amend
its Articles of Incorporation to provide that no director shall be liable to the
corporation or its shareholders for monetary damages for an act or omission in
the director's capacity as a director, provided that the liability of a director
is not eliminated or limited for: (i) any breach of the director's duty of
loyalty to the corporation or its shareholders; (ii) for acts or omissions not
in good faith or which involve intentional misconduct or knowing violation of
law; (iii) any transaction from which such director derived an improper personal
benefit; or (iv) an act or omission for which the liability of a director is
expressly provided by an applicable statute.

     We amended our Articles of Incorporation and added Article Ten adopting
such limitations on a director's liability. Our Articles of Incorporation also
provide in Article Ten, for indemnification of directors or officers in
connection with the defense or settlement of suits brought against them in their
capacities as directors or officers of the company, except in respect of
liabilities arising from gross negligence or willful misconduct in the
performance of their duties.

     Article VIII of our bylaws provides for indemnification of any person made
a party to a proceeding by reason of such person's status as a director, officer
or employee of the company, except in respect of liabilities arising from
negligence or misconduct in the performance of their duties.


                                      20

 
     We have obtained an insurance policy which provides for indemnification of
officers and directors of the company and certain other persons against
liabilities and expenses incurred by any of them in certain stated proceedings
and under certain stated conditions.

Item 17.  Undertakings.

     (a)  The undersigned Registrant hereby undertakes:

          (1)  To file, during any period in which offers or sales are being
               made, a post-effective amendment to this Registration Statement;

               (i)   To include any prospectus required by Section 10(a)(3) of
                     the Securities Act of 1933;

               (ii)  To reflect in the prospectus any facts or events arising
                     after the effective date of the Registration Statement (or
                     the most recent post-effective amendment thereof) which,
                     individually or in the aggregate, represent a fundamental
                     change in the information set forth in the Registration
                     Statement. Notwithstanding the foregoing, any increase or
                     decrease in volume of securities offered (if the total
                     dollar value of securities offered would not exceed that
                     which was registered) and any deviation from the low or
                     high end of the estimated maximum offering range may be
                     reflected in the form of prospectus filed with the
                     Commission pursuant to Rule 424(b) if, in the aggregate,
                     the changes in volume and price represent no more than a 20
                     percent change in the maximum aggregate offering price set
                     forth in the "Calculation of Registration Fee" table in the
                     effective Registration Statement;

               (iii) To include any material information with respect to the
                     plan of distribution not previously disclosed in the
                     Registration Statement, or any material change to such
                     information in the Registration Statement; provided,
                     however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not
                     apply if the information required to be included in a post-
                     effective amendment by those paragraphs is contained in
                     periodic reports filed by the Registrant pursuant to
                     Section 13 or Section 15(d) of the Securities Exchange Act
                     of 1934 that are incorporated by reference in the
                     Registration Statement.

          (2)  That, for the purpose of determining any liability under the
               Securities Act of 1933, each such post-effective amendment shall
               be deemed to be a new registration statement relating to the
               securities offered therein, and the offering of such securities
               at that time shall be deemed to be the initial bona fide offering
               thereof.

          (3)  To remove from registration by means of a post-effective
               amendment any of the securities being registered which remain
               unsold at the termination of the offering.

     (b)  The undersigned Registrant hereby undertakes that, for purposes of
          determining any liability under the Securities Act of 1933, each
          filing of the Registrant's annual report pursuant to Section 13(a) or
          Section 15(d) of the Securities Exchange Act of 1934 (and, where
          applicable, each filing of an employee benefit plan's annual report


                                      23

 
          pursuant to Section 15(d) of the Securities Exchange Act of 1934) that
          is incorporated by reference in the Registration Statement shall be
          deemed to be a new registration statement relating to the securities
          offered herein, and the offering of such securities at that time shall
          be deemed to be the initial bona fide offering thereof.

     (c)  Insofar as indemnification for liabilities arising under the
          Securities Act of 1933 may be permitted to directors, officers and
          controlling persons of the Registrant, pursuant to the foregoing
          provisions, or otherwise, the Registrant has been advised that in the
          opinion of the Securities and Exchange Commission such indemnification
          is against public policy as expressed in the 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 of 1933
          and will be governed by the final adjudication of such issue.

     (d)  The undersigned Registrant hereby undertakes that:

          (1)  For the purposes of determining any liability under the
               Securities Act of 1933, the information omitted from the form of
               prospectus filed as part of this Registration Statement in
               reliance upon Rule 430A and contained in a form of prospectus
               filed by the Registrant pursuant to Rule 424(b)(1) or (4) or
               497(h) under the Securities Act of 1933 shall be deemed to be
               part of this Registration Statement as of the time it was
               declared effective.

          (2)  For the purpose of determining any liability under the Securities
               Act of 1933, each post-effective amendment that contains a form
               of prospectus shall be deemed to be a new registration statement
               relating to the securities offered therein, and the offering of
               such new securities at that time shall be deemed to be the
               initial bona fide offering thereof.

     Pursuant to the requirements of the Securities Act of 1933, the Registrant
