[LOGO OF DATA RETURN APPEARS HERE]

                                  Common Stock

                                  -----------

This is an initial public offering of 6,250,000 shares of common stock of Data
Return Corporation. We are selling all of the shares of common stock under this
prospectus. The underwriters may, under some circumstances, purchase up to an
additional 937,500 shares of common stock from us at the initial public
offering price less the underwriting discount.

It is currently estimated that the initial public offering price will be
between $11.00 and $13.00 per share. We have applied to have our common stock
approved for listing on the Nasdaq National Market under the symbol "DRTN."

Microsoft Corporation has agreed to purchase directly from us $5.0 million of
our common stock, in a private placement that will occur the day after the
pricing of this offering. The price per share which Microsoft will pay us will
be the lesser of the midpoint of the lowest filing range and the price to
public.

See "Risk Factors" beginning on page 6 about the risks you should consider
before buying shares of our common stock.

Neither the Securities and Exchange Commission nor any other regulatory body
has approved or disapproved of these securities or passed upon the accuracy or
adequacy of this prospectus. Any representation to the contrary is a criminal
offense.

  This summary highlights the key information contained in this prospectus.
Because it is a summary, it does not contain all the information you should
consider before making an investment decision. You should read the entire
prospectus carefully, including the section titled "Risk Factors" and the
financial statements and the notes relating to those statements.

                                  Data Return

Our Company

  Data Return is a leading provider of advanced Internet hosting services based
on technologies developed by Microsoft Corporation. We focus primarily on
customers that are deploying sophisticated high-end web-based applications,
including electronic commerce, through which they can conduct transactions and
manage information worldwide over the Internet. We believe that hosting on the
Microsoft platform offers a greater opportunity than hosting on other
platforms. According to International Data Corp., Microsoft Windows NT will be
the key engine for growth within the worldwide server market.

  We provide high quality, high performance advanced hosting services, which
are comprised of:

  .  advanced managed services, whereby we configure, install, operate and
     maintain the hardware, software and network technologies necessary to
     implement and support our customers' complex, business-critical web
     sites and web-based applications.

  .  a scalable deployment architecture, which allows us to quickly and cost-
     effectively expand and enhance our customers' web sites; and

  .  high performance content delivery, which improves overall performance
     through increased speed and reliability.

  As of August 31, 1999, we hosted over 1,600 web sites for more than 800
customers. Our customers range in size from large Fortune 500 companies to
smaller businesses, both conventional and web-based. Some of our largest and
most recognizable customers are Ericsson, Executive Software, First USA,
Honeywell, Microsoft and Trane. We provide our services to companies across
many industries located primarily in North America and Europe. We also have a
small but growing customer base in South America, Asia, Africa and Australia.

  Level 3 Communications, Inc. and Compaq Computer Corporation are shareholders
of our company, and Microsoft has agreed to invest in our company. In addition
to their investments in our common stock, we have entered into strategic
agreements with each of these companies. We are currently Level 3's only
preferred provider of Microsoft-based advanced hosting solutions. Pursuant to
our agreement, we will train and team with Level 3's sales force to generate
new business opportunities. Further, we will be able to locate our servers and
related equipment in any of Level 3's existing or future U.S. facilities, or
gateways. In doing so, we expect to avoid the significant cost of constructing
additional data centers of our own. In addition, we will be able to utilize
Level 3's personnel to install our equipment at these gateways. Under our
agreement with Microsoft, we will license proprietary installation tools for
third-party hosted applications to Microsoft and train Microsoft's employees
and customers in the use of those tools. In exchange, Microsoft will provide us
technical consulting and marketing services. We also have a server purchase
agreement with Compaq which we believe strengthens our relationship with this
key vendor. We believe these relationships enhance our credibility with
potential customers and provide us with early access to new products, superior
technical services, training and new business development opportunities.

  We were incorporated in Texas in August 1997 by three former Microsoft
product support engineers and

                                       1
<PAGE>


have achieved an average quarterly revenue growth rate of 50% since October 1,
1997. However, we experienced net losses of approximately $1.3 million for the
year ended March 31, 1999, and we anticipate continuing and increasing losses.
We believe the following are among the key factors that have distinguished our
company and our offerings and that will continue to drive our growth:

  .  a full range of hosting services pre-packaged with defined pricing and
     feature sets;

  .  our exclusive focus and technical expertise on the Microsoft platform;

  .  high availability, high performance web hosting solutions which we
     believe will increasingly involve the clustering of multiple web,
     database and applications servers in order to securely and efficiently
     distribute web site content and related data across multiple and
     sometimes geographically distributed servers;

  .  an advanced and highly secure network architecture that, based on
     network improvements implemented during the week of August 16, 1999,
     since that period has delivered network performance faster on average in
     the United States compared to the single fastest backbone provider as
     measured by an independent third party (Keynote Systems) through its 65
     United States measurement agents dispersed across various cities;

  .  an integrated information system which automates our work flows and our
     service deployment processes;

  .  our exclusive focus on hosting, which allows us to avoid direct
     competition with software developers and systems integrators; and

  .  our commitment to building and maintaining strong relationships with
     members of the Microsoft developer community, many of whom have proven
     to be valuable sources of customers referrals.

Our Market Opportunity

  According to Forrester Research, the hosting market will grow from $0.9
billion in 1998 to $14.6 billion in 2003, a 76% compound annual growth rate. In
addition to the general expansion of the Internet, we believe that growth in e-
commerce will drive demand for outsourced advanced hosting services such as
ours because sites with e-commerce capabilities tend to be more complex.
Forrester Research projects that e-commerce will generate over $3.2 trillion in
revenue by 2003. In addition, we believe that the trend toward outsourcing the
hosting of web sites will continue as businesses increase the complexity of
their web sites and require greater reliability and interactivity for end
users. We also believe that these sites will increasingly be based on Microsoft
Internet technologies. According to IDC, Windows NT's market share will grow at
a compound annual growth rate of 25% from 1998 to 2003.

Our Strategy

  Our goal is to take advantage of the growth in Internet usage, e-commerce and
the outsourcing of hosting services to become the leading provider of advanced
hosting services. Our strategy to achieve this goal contains the following key
elements:

  .  maintain focus on advanced hosting on the Microsoft platform;

  .  offer a full range of highly scalable advanced hosting services;

  .  maintain non-capital intensive business model;

  .  enhance our marketing and sales programs;

  .  capitalize on key relationships;

  .  provide superior customer service;

  .  expand our data center presence; and

  .  expand into new hosting markets.

been audited by Ernst & Young LLP, independent auditors. The financial
statements for the three month periods ended June 30, 1998 and 1999 have not
been audited. The unaudited financial statements include all adjustments,
consisting of normal recurring accruals, which Data Return considers necessary
for a fair presentation of its financial position and the results of its
operations for these periods.

  When you read this summary historical financial data, it is important that
you read it in conjunction with the historical financial statements and related

(1) EBITDA consists of loss from operations plus depreciation and amortization,
    including amortization of unearned stock based compensation. EBITDA does
    not represent funds available for management's discretionary use and is not
    intended to represent cash flow from operations as measured under generally
    accepted accounting principles. EBITDA should not be considered as an
    alternative to net loss or net cash used in operating activities, but may
    be useful to investors as an indication of operating performance. Our
    calculations of EBITDA may not be consistent with calculations of EBITDA
    used by other companies.

                                  RISK FACTORS

  Investing in our common stock involves a high degree of risk. You should
carefully consider the risks and uncertainties described below before you
purchase any of our common stock. While we have described all risks and
uncertainties that we believe are material to our business, other risks and
uncertainties that affect our business operations may arise or become material
in the future.

  If we cannot address the following risks and uncertainties effectively, our
business, financial condition or results of operations could be materially and
adversely affected. In this event, the trading price of our common stock could
decline and you could lose all or a part of your investment.

  This prospectus also contains forward-looking statements that involve risks
and uncertainties. Our actual results could differ materially from those
anticipated in the forward-looking statements as a result of several factors,
including the risks and uncertainties described below and elsewhere in this
prospectus.

Our business and prospects are difficult to evaluate because we have a limited
operating history and our business model is still evolving.

  We were incorporated in August 1997 and commenced operations in September of
that year with a focus on advanced hosting services. As a result, we have a
limited operating history and our business model is evolving. We may not be
able to successfully implement our business plan or adapt it to changes in the
market. If we are not able to do so, our business, results of operations and
financial condition will be adversely affected.

We have a history of substantial losses, and we anticipate continuing and
increasing losses.

  We have experienced operating losses and negative cash flows from operations
in each quarterly and annual period since incorporating in 1997. We experienced
net losses of approximately $ 635,000, or 52% of revenues, for the three month
period ended June 30, 1999, and $1.3 million, or 68% of revenues, for the year
ended March 31, 1999. As of June 30, 1999, we had an accumulated deficit of
approximately $2.1 million. We expect our operating losses to increase in the
future due primarily to an increase in operating expenses to expand our
marketing and sales operations, develop our distribution channel, fund greater
levels of research and development, support and improve our operational and
financial systems and broaden customer service and support. We cannot assure
you that we will ever be profitable on a quarterly or annual basis, or that if
we achieve profitability, it will be sustainable.

Our quarterly and annual results may fluctuate, resulting in fluctuations in
the price of our common stock.

  Our operating results may fluctuate significantly in the future on a
quarterly and annual basis. Because of these fluctuations, comparisons of our
operating results from period to period are not necessarily meaningful and
should not be relied upon as an indicator of future performance. We expect to
continue to experience significant fluctuations as a result of a variety of
factors, many of which are outside of our control. The following factors could
affect our operating results:

  .  size and timing of customer installations and related payments;

  .  fluctuations in data and voice communications costs;

  .  timing and magnitude of capital expenditures;

  .  costs relating to the expansion of operations;

  .  customer discounts and credits;

                                       6
<PAGE>

  .  changes in our pricing policies or those of our competitors; and

  .  economic conditions specific to the hosting industry, as well as general
     economic conditions.

  We plan to increase our operating expenses to develop our business. If our
revenues do not increase as quickly as our expenses, our operating results will
suffer.

  For these and other reasons, in future periods our operating results may fall
below the expectations of securities analysts or investors, which could result
in widely varying stock prices and negatively affect the market price of our
common stock.

We rely on our strategic relationship with Level 3, and if this relationship is
terminated or deteriorates our business will suffer.

  We recently entered into a strategic relationship with Level 3. Level 3 is a
communications and information services company that is building an advanced
facilities-based communications network through which it provides co-location,
Internet connectivity and other services. We are currently Level 3's only
preferred provider of Microsoft-based advanced hosting solutions. Our ability
to increase demand for our services depends in part upon Level 3's referrals of
new customers to us. This relationship is non-exclusive, and our marketing
agreement can be terminated by Level 3 if we default on our obligations under
this agreement or are acquired by a competitor of Level 3. If Level 3 fails to
refer new customers to us or refers potential customers to our competitors or
if our relationship with Level 3 deteriorates or is terminated for any reason,
we may not be able to increase our customer base and, therefore, our revenues
as rapidly as we anticipate and our business would suffer. If we fail to train
Level 3's sales personnel, or fail to train them adequately, we will not
realize some of the benefits that we believe we will receive under this
arrangement, including customer referrals. As part of our relationship, we have
committed to purchase a fixed amount of services from Level 3, including, among
other things, bandwidth, co-location space, installation and maintenance
services, over the next five years. We will incur these expenses even if
anticipated increases in sales do not materialize or, in some circumstances, if
the agreement is terminated. We have also agreed to purchase most of our
bandwidth and co-location requirements to the extent they meet our then-current
performance and capacity requirements. We are required to purchase these
services from Level 3 even if these services are available at lower prices from
alternative vendors.

  Our relationship with Level 3 also entitles us to offer our services from all
existing and future U.S. Level 3 data centers. We currently rely on Level 3 to
provide most of the data center capacity that we need to provide our hosting
services, and in the future we will be required to purchase most of our data
center capacity from Level 3. Further, Level 3 will provide personnel at these
data centers to install equipment and assist with support as necessary for us
to deliver service in these facilities. If Level 3 fails to perform these
services in a timely or effective manner, or at all, we would be required to
make alternate arrangements, possibly including hiring additional
implementation engineers. In addition, if our relationship with Level 3 is
terminated or if Level 3 does not provide the data center capacity that we
need, we would be required to seek arrangements with other data center
providers or construct our own data centers. We cannot be certain that
alternate data center capacity will be available on commercially reasonably
terms or at all. We currently rely, and for the foreseeable future will
continue to rely, on Level 3 to provide bandwidth and other networking
services. If we are unable to obtain these services from Level 3, we would be
required to seek arrangements with other providers of these services, and we
cannot be certain that alternate services will be available on commercially
reasonable terms or at all.

Our success depends on Microsoft's continued success, and the loss or
deterioration of our relationship with Microsoft could harm our business and
have an adverse impact on our revenues.

  We focus on advanced hosting services for Microsoft-based Internet
technologies. If these technologies are not widely used building blocks for
advanced Internet sites in the future, the demand for our services would
decrease and our business would be adversely affected.


                                       7
<PAGE>

  Our relationship with Microsoft is informal. We believe this relationship
provides us with access to developments in Microsoft products before they are
generally available, which allows us to maintain and enhance our technical
expertise. If our relationship with Microsoft deteriorates or if we lose some
of the status or privileges we currently enjoy, our technical expertise could
be adversely affected. Our ability to market our services as a provider of
advanced hosting services for Microsoft-based Internet technologies would also
be adversely affected if Microsoft does not continue to confer certifications
and designations on us, or changes our current certifications or designations.
We do not have a written agreement with Microsoft relating to these
certifications or designations. Some of our competitors also have received
these certifications and designations. For example, we are aware of seven other
businesses that have been designated as Microsoft Advanced Hosting Partners.
These certifications and the number of businesses holding them are described on
page 40 under the heading "Microsoft." Microsoft confers these certifications
unilaterally and in its sole discretion and could change them at any time.
Thus, we cannot be certain that we will continue to enjoy them.

If we are unable to expand our network infrastructure to meet increasing
demand, we could lose customers and our operating results could suffer.

  We must continue to expand and adapt our network infrastructure to
accommodate the increasing number of customers, the amount of information they
wish to transmit and their changing requirements. We face risks related to our
network's ability to be scaled to meet increasing customer levels while
maintaining acceptable performance levels. The expansion and adaptation of our
networking and hosting facility infrastructure will require substantial
financial, operational and management resources as we negotiate bandwidth
capacity with existing and other network infrastructure suppliers. If we are
required to expand our network significantly and rapidly due to increased
usage, additional stress will be placed upon our network hardware, traffic
management systems and hosting facilities as well as our financial, operational
and management resources. Due to the limited deployment of our services to
date, the ability of our network to support a substantially larger number of
customers at high transmission speeds is unknown.

If the network providers upon which we rely fail to provide reliability,
capacity and performance for our network, we could lose customers and our
operating results could suffer.

  Our success partly depends upon the capacity, reliability and security of our
network infrastructure, including the capacity leased from our network
suppliers. Our network currently delivers service through Level 3, MCI
WorldCom, Inc., including UUNET Technologies, Inc., e.spire Communications,
Inc., Sprint Corporation, Digex, Incorporated, Cable & Wireless plc and SAVVIS
Communications Enterprises, LLC. Some of these suppliers are also our
competitors. In the future, we will be required to purchase most of our network
capacity from Level 3 to the extent they meet our then-current performance and
capacity requirements. We depend on these companies to provide uninterrupted
and error-free service through their telecommunications networks. As our
customers' usage of telecommunications capacity increases, we will need to make
additional investments in our infrastructure to maintain adequate data
transmission speeds, the availability of which may be limited or the cost of
which may be significant. Our average utilization of our network capacity was
17.7% during the last year. We monitor all network links to prevent their being
utilized in excess of their recommended capacity. If capacity is not available
to us as our customers' usage increases, our network may not be able to achieve
or maintain sufficiently high data transmission capacity, reliability or
performance. In addition, our business would suffer if our network suppliers
increased the prices for their services and we were unable to pass along any
increased costs to our customers. Any failure on our part or the part of our
third-party suppliers to achieve or maintain high data transmission capacity,
reliability or performance could significantly reduce customer demand for our
services and damage our business.

We may not be able to deliver our services and our business may suffer if our
third-party suppliers do not provide us with key components of our network
infrastructure.

  We depend on other companies to supply key components of our network
infrastructure. Any failure to obtain needed products or services in a timely
fashion or at an acceptable cost could adversely affect our

                                       8
<PAGE>

business. We buy servers, routers and switches on an as-needed basis and
therefore do not carry significant inventories of them. We also have no
guaranteed supply arrangements with our vendors. We currently only use servers
from Compaq and rely on Compaq to provide us with access to Compaq technical
personnel. We recently entered into an agreement with Compaq under which we
have agreed for the next three years to purchase from Compaq the lesser of
2,000 servers or the number of servers reasonably necessary to adequately
operate our business consistent with our business plan. Our requirement to
purchase these servers is contingent upon Compaq providing financing for the
servers on competitive terms, upon the price, performance and quality of the
Compaq servers being reasonably satisfactory to us and upon Compaq's commitment
to deliver these servers on the schedule we request. In addition, we rely on
Cisco Systems, Inc. and Alteon to supply equipment critical to our network, but
we do not have a supply agreement with either of them. If this equipment were
to become unavailable on terms acceptable to us, we would be forced to find
alternative equipment. The inability to obtain equipment or technical services
from Compaq, Cisco or Alteon on terms acceptable to us would force us to spend
time and money selecting and obtaining new equipment, training our personnel to
use different equipment and deploying alternative components needed to
integrate the new equipment, and as a result our business could be adversely
affected.

Because we operate in a new and evolving market with uncertain prospects for
growth, we may be unable to sustain growth in our customer base and our
operating results may suffer.

  Our market is new and rapidly evolving. Growth in demand for and acceptance
of advanced hosting services are highly uncertain. Businesses may not be aware
of the potential benefits of outsourcing or may find it cheaper, more secure or
otherwise preferable to host their web sites internally. Internet technologies,
such as e-commerce applications, which require advanced hosting, may not grow
as rapidly as we expect. If the market for advanced hosting services fails to
grow or grows more slowly than we anticipate, our business, operating results
and financial condition will be adversely affected. Growth in the demand for
our products and services may be inhibited, and we may be unable to sustain
growth in our customer base, for a number of reasons, including:

  .  our inability to market our products and services in a cost-effective
     manner to new customers;

  .  the inability of customers to differentiate the products and services we
     offer from those of our competitors;

  .  the termination of our customer contracts, which can generally be
     canceled on 30 days' notice;

  .  our inability to strengthen awareness of our brand; and

  .  reliability, quality or compatibility problems with our services.

We may not be able to adapt to evolving technologies and customer demands,
which could cause our business to suffer.

  Our market is characterized by rapidly changing technology, evolving industry
standards and frequent new product announcements. These characteristics are
magnified by the recent growth of the Internet and the intense competition in
our industry. We are also subject to risks from technological changes in the
way hosting solutions are marketed and delivered. To be successful, we must
adapt to our rapidly changing market by continually improving the performance,
features and reliability of our services and modifying our business strategies
accordingly. We could also incur substantial costs if we need to modify our
services or infrastructure in order to adapt to these changes. Our business
would suffer if we fail to respond to these changes in a timely and cost-
effective manner or at all.

Our business will suffer if Internet usage does not continue to increase or if
the Internet fails to perform reliably.

  Use of the Internet for retrieving, sharing and transferring information
among businesses, consumers, suppliers and partners has recently begun to
increase rapidly. Our success depends in large part on continued

                                       9
<PAGE>

growth in the use of the Internet, and we would be adversely affected if
Internet usage does not continue to grow. Internet usage and growth may be
inhibited for a number of reasons, such as:

  .  inadequate network infrastructure;

  .  security concerns;

  .  uncertainty of legal and regulatory issues concerning the use of the
     Internet;

  .  inconsistent quality of service;

  .  lack of availability of cost-effective, reliable, high-speed service;
     and

  .  failure of Internet use to expand internationally.

  If Internet usage grows, the Internet infrastructure may not be able to
support the demands placed on it by this growth, or its performance and
reliability may decline. For example, web sites have experienced interruptions
in service as a result of outages and other delays occurring throughout the
Internet network infrastructure. If these outages or delays occur frequently,
use of the Internet as a commercial or business medium could in the future grow
more slowly or decline, which would adversely affect our business.

Failure of our operating and financial systems to keep pace with the
anticipated growth in our business could result in customer dissatisfaction,
operating inefficiencies and lost revenue opportunities.

  The rapid growth of our business and our service offerings has placed, and is
likely to continue to place, a significant strain on our operating and
financial resources. Our future performance will partly depend on our ability
to manage our growth effectively, which will require that we further develop
our operating and financial system capabilities and controls. We are in the
process of implementing new billing and other management information systems.
If our information systems, including the systems that we are currently
implementing, and other infrastructure are unable to support the demands placed
on them by the rapid growth in our business, we may be forced to implement new
systems. If we fail to improve our operational systems or to expand our
customer service capabilities to keep pace with the growth of our business, we
could experience customer dissatisfaction, cost inefficiencies and lost revenue
opportunities, which could harm our operating results. We may not be able to
successfully implement these systems when needed or they may not perform
reliably.

We may not be able to successfully sustain our growth if we are unable to
attract and retain additional highly skilled personnel.

  We are currently experiencing rapid growth and intend to continue expanding.
Since incorporating in August 1997, we had grown from five to 79 employees as
of August 31, 1999. We believe that we will need to hire over 150 additional
personnel in all areas of our business over the next 12 months. If we do not
succeed in attracting and retaining new, qualified personnel and/or retaining
our current personnel, our business could suffer.

  We must expand our direct and indirect sales operations to increase market
awareness of our products and generate increased revenues. We cannot be certain
that we will be successful in these efforts. We plan to increase our sales
force significantly in the second half of 1999. Newly-hired employees will
require training and it will take time for them to achieve full productivity.
Also, through our relationship with Level 3, we intend to begin training their
sales force to sell our products and services in October 1999. We cannot be
certain that we will be able to hire enough qualified individuals in the
future, that newly-hired employees will achieve necessary levels of
productivity or that our Level 3 relationship will result in increased sales.

                                       10
<PAGE>

We may need additional capital to fund our operations and finance our growth,
and we may not be able to obtain it on terms acceptable to us or at all.

  We believe that our existing capital resources, including the anticipated
proceeds of this offering, will enable us to maintain our current and planned
operations for at least the next 12 months. However, we may require additional
funds during or after that 12-month period. Any required financing may not be
available or may be available only on terms that are not favorable to us.
Further, if additional funds are raised through the issuance of additional
equity securities, the percentage ownership of our shareholders would be
diluted. Any new equity securities may have rights, preferences or privileges
senior to those of our common stock.

We could experience system failures which could harm our business and
reputation.

  To succeed, we must be able to operate our network management infrastructure
around the clock without interruption. Our operations depend upon our ability
to protect our network infrastructure, equipment and customer files against
damage from human error, fire, earthquakes, hurricanes, floods, power loss,
telecommunications failures, sabotage, intentional acts of vandalism and
similar events. Our servers and network infrastructure are located in the
Dallas and Fort Worth, Texas metropolitan area. Even though we have attempted
to minimize risk through redundant systems, we do not have a comprehensive
disaster recovery plan and the occurrence of a natural disaster or other
unanticipated problems at any of our data centers could result in interruptions
in the services we provide to our customers.

  Although we have attempted to build redundancy into our network and hosting
infrastructure, we have experienced interruptions in service in the past. We
have experienced partial system failures due to routing problems, hard drive
failures, database corruption and other computer failures. Our network is
subject to various points of failure, and a problem with our routers, switches
or other equipment could cause an interruption in the services we provide to
some of our customers. Any future interruptions could:

  .  cause customers or end users to seek damages for losses incurred;

  .  require us to replace existing equipment or add redundant facilities;

  .  damage our reputation for reliable service;

  .  cause existing customers to cancel their contracts; or

  .  make it more difficult for us to attract new customers.

  Any of these results could damage our business.

Disruption of our services caused by unknown software defects could harm our
business and reputation.

  Our service offerings depend on complex software, including software licensed
from third parties and our proprietary software tools. Complex software often
contains defects, particularly when first introduced or when new versions are
released. We may not discover software defects that affect our new or current
services or enhancements until after they are deployed. Although we have not
experienced any material software defects to date, it is possible that defects
may occur in the software. These defects could cause service interruptions,
which could damage our reputation or increase our service costs, cause us to
lose revenue, delay market acceptance or divert our development resources.

Our business and reputation will suffer if we do not prevent security breaches.

  Despite our design and implementation of a variety of network security
measures, unauthorized access, computer viruses, accidents, misconduct
resulting in disruptions and other disruptions could occur. In addition, we may
incur significant costs to prevent breaches in security or to alleviate
problems caused by breaches. We rely on third-party suppliers such as Level 3
to protect our equipment and hardware against breaches in

                                       11
<PAGE>

security. We cannot be certain that they will provide adequate security. While
we have experienced no material security breaches in the past, any breaches
that may occur could result in liability to us, loss of existing customers or
the deterrence of future customers.

Our limited ability or failure to protect our intellectual property may
adversely affect our ability to compete.

  Third parties may infringe or misappropriate our technology or proprietary
rights, which could have an adverse effect on our business, results of
operations or financial condition. In addition, our competitors or potential
competitors may independently develop technologies that are equivalent or
superior to our technology. We rely on a combination of copyright, trademark,
service mark and trade secret laws to protect our intellectual property. We are
in the process of filing federal registrations for the trademark "Data Return,"
as well as other service and trademarks which incorporate the Data Return name.
We also have internally developed software and other tools that are important
to our business for which we rely on copyright protection. We have entered into
some contractual arrangements with our employees and contractors as well as
suppliers, distributors and some of our key customers in order to limit access
to, and any disclosure of, our proprietary information. The steps we have taken
to protect our intellectual property may be insufficient. We may need to take
legal action to protect our intellectual property rights, which could be costly
and divert the attention of our technical and management personnel.

We may be accused of infringing the proprietary rights of others, which could
subject us to costly and time consuming litigation.

  In addition to the technologies we develop or have developed, we license
certain technologies from third parties and may license additional technologies
in the future. Although we have not been accused of infringing the proprietary
rights of others in the past, we could become subject to infringement actions
based upon our internally developed technologies or technologies licensed from
third parties. Any of these claims, with or without merit, could subject us to
costly litigation and divert the attention of our technical and management
personnel. In addition, third parties may change the terms of their license
agreements in ways that would prevent us from using technologies licensed from
them on commercially reasonable terms or that would prevent us from using them
at all. We may not be able to replace those technologies with technologies that
have the same features or functionality on commercially reasonable terms or at
all.

If we do not adequately address Year 2000 issues, we may incur significant
costs and our business could suffer.

  Currently, many computer and software products are coded to accept only two-
digit entries in the date code field. These date code fields will need to
accept four-digit entries to distinguish 21st century dates from 20th century
dates. As a result, many companies' software and computer systems may need to
be upgraded or replaced in order to comply with Year 2000 requirements. We
cannot predict whether our Year 2000 compliance issues will require us to
upgrade or replace our systems and equipment. Should we be required to upgrade
or replace our systems and equipment, it could represent a significant cost to
us. If we are not successful in identifying and planning for Year 2000 issues,
our business operations could be materially and adversely affected.
Additionally, we cannot evaluate our customers' Year 2000 readiness. Some of
our customers' sites may fail due to Year 2000 issues and any failures may
affect other customers' sites or our network. Also, to the extent that a
customer's site is not functioning correctly and it is not possible to
determine that the malfunction is caused by the customer's software, the
customer may request service credits or we might otherwise have a difficult
time realizing the expected revenues from that customer. Level 3 has indicated
that they are Year 2000 compliant. However, we have not undertaken any
independent assessment of Level 3's Year 2000 compliance and any failure of
Level 3's network due to Year 2000 issues could cause a disruption in our
services, which could cause us to lose customers.

  The worst-case scenario related to the Year 2000 issue would be an overall
failure of the Internet, the telecommunications infrastructure and the
electrical grid. If this happened, we would be unable to service our

                                       12
<PAGE>

customers for an uncertain period of time. Any widespread disruption to these
systems would have unpredictable and potentially severe impacts on our business
and financial condition. We currently have no contingency plan to deal with
this worst-case scenario.

  See "Management's Discussion and Analysis of Financial Condition and Results
of Operations--The Year 2000."

Regulatory and legal uncertainties could result in significant costs or
otherwise harm our business.

  The success of our business depends on the growth of the Internet. Laws and
regulations directly applicable to commerce or communications over the Internet
are becoming increasingly prevalent. However, the law of the Internet remains
largely unsettled. The adoption or modification of laws or regulations relating
to the Internet could adversely affect our business if they impose a direct
cost on us or if they curtail the growth of the Internet. If liability for
materials carried on or disseminated through their systems is imposed on
service providers, we would make efforts to implement measures to reduce our
exposure to such liability. Such measures could require us to expend
substantial resources or discontinue certain product or service offerings. In
addition, increased attention to liability issues, as a result of lawsuits,
legislation and legislative proposals, could divert management attention,
result in unanticipated expenses and harm our business. If legislation that
makes transacting business over the Internet, such as e-commerce, less
favorable or otherwise curtails the growth of the Internet is adopted in the
U.S. or internationally, our business would suffer. See "Business--Government
Regulation."

The loss of key personnel including our Chairman and Chief Executive Officer or
our President and Chief Operating Officer could harm our business.

  We depend on the continued service of our key technical, sales and senior
management personnel, including Sunny C. Vanderbeck, our Chairman and Chief
Executive Officer, and Michelle R. Chambers, our President and Chief Operating
Officer. We have entered into three-year employment agreements with
Mr. Vanderbeck and Ms. Chambers, but any of our officers or employees can quit
at any time. Losing one or more of our key employees could harm our business.

We operate in an extremely competitive market, and our business would suffer if
we are unable to compete effectively.

  The market for hosting and Internet services is highly competitive. There are
few substantial barriers to entry to keep new competitors from entering this
market. We expect that we will face additional competition from existing
competitors and new market entrants in the future. Many of our competitors have
substantially greater financial, technical and marketing resources, larger
customer bases, longer operating histories, greater name recognition and more
established relationships in the industry than we do. As a result, some of
these competitors may be able to:

  .  develop and expand their network infrastructures and service offerings
     more rapidly;

  .  adapt to new or emerging technologies and changes in customer
     requirements more quickly;

  .  take advantage of acquisition and other opportunities more readily;

  .  devote greater resources to the marketing and sales of their services;
     and

  .  adopt more aggressive pricing policies.

                                       13
<PAGE>

  In addition, some of our competitors have entered and will likely continue to
enter into joint ventures or other arrangements to provide additional services
competitive with those provided by us. We believe that the market in which we
compete is likely to experience consolidation in the near future, which could
result in increased competition on price and other factors that could adversely
affect our business.

  In an effort to gain market share, some of our competitors have offered
hosting services similar to ours at prices lower than ours or with incentives
not matched by us. In addition, some of our competitors may be able to provide
customers with additional benefits that could reduce the overall costs of their
services relative to ours. We may not be able to reduce the pricing of our
services or offer incentives in response to the actions of our competitors
without an adverse impact on our business.

  See "Business--Competition."

Because we have customers internationally, our business may be adversely
affected by foreign political and economic conditions.

  In fiscal 1999, approximately 8% of our revenues were derived from our
customers located in Europe and Asia. In addition, we expect to begin operating
from Level 3's data center in London, England during the second half of 1999.
Our success depends in part on expanding our customer base internationally and
our ability to successfully operate from data centers in foreign markets.
Because our international sales are denominated in U.S. dollars, currency
fluctuations may deter foreign customers from purchasing our services. In
addition, we face risks in operating and servicing customers in foreign
markets, such as:

  .  different Internet access fees;

  .  different technology standards;

  .  different privacy, censorship and service provider liability standards
     and regulations; and

  .  less protective intellectual property laws.

Any of these risks could adversely affect our ability to operate or expand
internationally, which would limit the growth of our business.

We have broad discretion as to the use of proceeds from this offering, and our
use of proceeds may not yield a favorable return.

  We intend generally to use the net proceeds from this offering to fund our
operations, fund our capital expenditures, expand our marketing and sales
activities and for working capital and other general corporate purposes. We may
also acquire or make investments in other businesses, products, services or
technologies, and, if we do, we may not be able to make those acquisitions or
investments on commercially acceptable terms or we could have difficulty
assimilating and integrating any acquired businesses, technologies, services or
products. We have not yet determined the actual expected expenditures and thus
cannot estimate the amounts to be used for each specified purpose. The actual
amounts and timing of these expenditures will vary significantly depending on a
number of factors, including, but not limited to, the amount of cash generated
by our operations and the market response to the introduction of any new
service offerings. Depending on future developments and circumstances, we may
use some of the proceeds for uses other than those described above. Our
management will have significant flexibility in applying the net proceeds of
this offering. We cannot be certain that our use of the proceeds will yield a
favorable return. See "Use of Proceeds."

Our principal shareholders, directors and executive officers will own
approximately 76% of our common stock, which may allow them to exert influence
over us or to prevent a change of control.

  After this offering our shareholders who currently own over 5% of our common
stock, our directors and our executive officers will beneficially own
approximately 76% of our outstanding common stock. These shareholders will be
able to exercise significant influence over all matters requiring shareholder
approval, including the election of directors and approval of significant
corporate transactions. This concentration of ownership may also delay or
prevent a change in control of us even if beneficial to our shareholders.

                                       14
<PAGE>

Some provisions of our articles, bylaws and rights plan and of Texas law could
delay or prevent a change of control which could adversely affect our stock
price.

  Our articles of incorporation and bylaws contain provisions that could make
it more difficult for a third party to acquire us, even if doing so would be
beneficial to our shareholders. These provisions could limit the price that
investors might be willing to pay in the future for shares of our common stock.
Some of these provisions:

  .  authorize the issuance of preferred stock which can be created and
     issued by our board of directors without prior shareholder approval,
     commonly referred to as "blank check" preferred stock, with rights
     senior to those of common stock;

  .  prohibit certain shareholder actions by written consent;

  .  establish advance notice requirements for submitting nominations for
     election to our board of directors and for proposing matters that can be
     acted upon by shareholders at a meeting; and

  .  provide for a classified board of directors with staggered three-year
     terms.

  We are also subject to certain provisions of Texas law which could delay,
deter or prevent a change in control of us.

  We intend to adopt a shareholder rights plan before this offering is
consummated. This plan will entitle our shareholders to rights to acquire
additional shares of our common stock when a third party acquires 15% of our
common stock or commences or announces its intent to commence a tender offer
for at least 15% of our common stock. This plan could delay, deter or prevent a
change in control of us.

You will suffer immediate and substantial dilution.

  The initial public offering price of our common stock is expected to be
substantially higher than the net tangible book value of our common stock.
Therefore, if you purchase our common stock in this offering, you will incur
immediate dilution of approximately $9.42 in the net tangible book value per
share of common stock from the price per share that you pay for such common
stock (based upon an assumed initial public offering price of $12.00 per
share). You will also experience additional dilution upon the exercise of
outstanding stock options at prices below the initial public offering price.

Future sales of our common stock could cause our stock price to decline.

  After this offering is completed, 34,422,625 shares of our common stock will
be issued and outstanding, assuming no exercise of the underwriters' over-
allotment option. All of the shares of our common stock sold in this offering
will be freely tradable unless purchased by our "affiliates." In connection
with this offering, our officers, directors and shareholders not purchasing in
the offering who together own approximately 28,172,625 shares of our common
stock agreed to refrain from selling any shares of our common stock for a
period of 180 days after the date of this prospectus. We cannot be sure what
effect, if any, future sales of our common stock or the availability of shares
for future sale will have on the market price of our common stock. The market
price of our common stock could drop due to sales of a large number of shares
of our common stock in the market after this offering or the perception that
these sales could occur. These factors could also make it more difficult to
raise funds through future offerings of our common stock. There will be
34,422,625 shares outstanding upon the completion of this offering, of which
20,551,600 shares will become available for sale to the public 180 days from
the date of this prospectus, subject in some cases to volume limitations.

                FORWARD-LOOKING STATEMENTS AND ASSOCIATED RISKS

  Some of the information in this prospectus contains forward-looking
statements. These statements include, among others, statements relating to
expenditure levels, the adequacy of capital resources and plans for expansion
of our marketing and sales efforts, risk factors, use of proceeds, liquidity,
strategy, sales and technology and network operations. These statements may be
found under Prospectus Summary, Risk Factors, Management's Discussion and
Analysis of Financial Condition and Results of Operations and Business.
Forward-looking statements are typically identified by the use of terms such as
"may," "will," "expect," "intend," "anticipate," "estimate" and similar words,
although some forward-looking statements are expressed differently. You should
be aware that our actual results could differ materially from those contained
in the forward-looking statements due to a number of factors, including without
limitation, changes in external competitive market factors, changes in our
business strategy or an inability to execute our strategy, unanticipated
changes in the hosting industry, the economy in general and changes in the use
of the Internet. We cannot guarantee future results, levels of activity,
performance or achievements. You should also consider carefully the statements
under "Risk Factors" and other sections of this prospectus, which address
additional factors that could cause our actual results to differ from those set
forth in the forward-looking statements.

                                USE OF PROCEEDS

  We estimate that the net proceeds from the sale of 6,250,000 shares of common
stock we are offering will be approximately $68.8 million at an assumed initial
public offering price of $12.00 per share and after deducting the estimated
underwriting discounts and commissions and estimated offering expenses. If the
underwriters' over-allotment option is exercised in full, we estimate that the
net proceeds will be approximately $79.2 million.

  We currently intend to use approximately $25.0 million of the net proceeds to
fund capital expenditures, consisting of the purchase of servers and other
hardware. We also intend to use $192,000 to pay off and cancel our notes
payable to Bank One of Texas, N.A. that we entered into in July 1998 in
connection with the purchase of equipment. We intend to use the balance of the
net proceeds for working capital and other general corporate purposes,
including funding our anticipated operating losses, expanding our marketing and
sales activities and hiring additional personnel. In addition, we may use some
of the proceeds for strategic investments and acquisitions. However, we have no
current plans, agreements or commitments with respect to any acquisition or
investments of this type. Our management may spend the proceeds from this
offering in ways which the shareholders may not deem desirable.

  The timing and amount of our actual expenditures will be based on many
factors, including cash flows from operations and the growth of our business.

  Until we use the net proceeds of this offering for the above purposes, we
intend to invest the funds in short-term, investment grade, interest-bearing
securities. We cannot predict whether the proceeds invested will yield a
favorable return.

                                DIVIDEND POLICY

  We have never paid any cash dividends on our capital stock. We anticipate
that we will retain earnings to support operations and to finance the growth
and development of our business. Therefore, we do not expect to pay cash
dividends in the foreseeable future.

                                 CAPITALIZATION

  The following table sets forth our capitalization on June 30, 1999:

  .  on an actual basis;

  .  on a pro forma basis to reflect the net proceeds from private sales of
     4,296,468 shares of our common stock to Level 3, Compaq and ZeroDotNet,
     Inc. between June 30, 1999 and the date of this prospectus; see "Certain
     Transactions" on page 56 for a description of these transactions; and

  .  on a pro forma as adjusted basis to give effect to the sale of an
     assumed 416,667 shares of our common stock to Microsoft at an assumed
     price of $12.00 per share and the sale of the shares of common stock we
     are offering, at an assumed initial public offering price of $12.00 per
     share (based upon the midpoint of the filing range), after deducting the
     estimated underwriting discounts and commissions and estimated offering
     expenses that we will pay and the application of the estimated net
     proceeds as described under "Use of Proceeds," including repayment of
     the long term portion of notes payable.

  This table should be read in conjunction with the audited financial
statements and the notes relating to those statements included elsewhere in
this prospectus.

                                    DILUTION

  Our net tangible book value on June 30, 1999, was approximately $4,024,300 or
$0.17 per share. "Net tangible book value" is total assets minus the sum of
liabilities and intangible assets. "Net tangible book value per share" is net
tangible book value divided by the total number of shares outstanding.

  After giving effect to adjustments relating to the offering described below,
our pro forma net tangible book value on June 30, 1999, would have been
$88,774,300 or $2.58 per share. The adjustments made to determine pro forma net
tangible book value per share are the following:

  .  an increase in total assets to reflect the net proceeds from private
     sales of 4,296,468 shares of our common stock;

  .  an increase in total assets to reflect the estimated net proceeds from
     the sale of 416,667 shares to Microsoft and the sale of 6,250,000 shares
     in the offering as described under "Use of Proceeds" (assuming an
     initial public offering price of $12.00 per share (based upon the
     midpoint of the filing range)); and

  .  the addition of the number of shares offered by this prospectus and by
     private sales of shares to the number of shares outstanding.

  The following table illustrates the pro forma increase in net tangible book
value of $2.04 per share and the dilution (the difference between the offering
price per share and net tangible book value per share) to new investors.
Dilution per share in the table below does not include dilution from the
exercise of options outstanding at June 30, 1999, to purchase 5,924,725 shares
of common stock at a weighted average exercise price of $0.14 per share. If
these options are exercised, new investors will experience additional dilution.

                            SELECTED FINANCIAL DATA

  The following selected financial data should be read in conjunction with the
financial statements, related notes and other financial information contained
later in this prospectus. You should also read "Management's Discussion and
Analysis of Financial Condition and Results of Operations," contained later in
this prospectus. The Statements of Operations data for the period from
September 22, 1997 (inception) to March 31, 1998 and the year ended March 31,
1999 and the balance sheet data as of March 31, 1998 and 1999 are derived from
the financial statements of Data Return that have been audited by Ernst & Young
LLP, independent auditors. The financial data for the three month periods ended
June 30, 1998 and 1999 are derived from unaudited financial statements. The
unaudited financial statements include all adjustments, consisting of normal
recurring accruals, which Data Return considers necessary for a fair
presentation of its financial position and the results of its operations for
these periods. The results of operations for the three month period ended June
30, 1999 are not necessarily indicative of the results of operations to be
expected for the full year.

(1) EBITDA consists of loss from operations plus depreciation and amortization,
    including amortization of unearned stock based compensation. EBITDA does
    not represent funds available for management's discretionary use and is not
    intended to represent cash flow from operations as measured under generally
    accepted accounting principles. EBITDA should not be considered as an
    alternative to net loss or net cash used in operating activities, but may
    be useful to investors as an indication of operating performance. Our
    calculations of EBITDA may not be consistent with calculations of EBITDA
    used by other companies.

(2) On a pro forma basis to reflect the private sales of 4,296,468 shares of
    our common stock between June 30, 1999 and the date of this prospectus.

(3) On a pro forma as adjusted basis to give effect to the sale of an assumed
    416,667 shares of our common stock at an assumed price of $12.00 per share
    to Microsoft and the sale of 6,250,000 shares of common stock we are
    offering under this prospectus, at an assumed initial public offering price
    of $12.00 per share (based upon the midpoint of the filing range), after
    deducting the estimated underwriting discounts and commissions and
    estimated offering expenses that we will pay and the application of the
    estimated net proceeds from this offering as described under "Use of
    Proceeds," including repayment of the long term portion of notes payable.

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

  You should read the following discussion together with the financial
statements and other financial information included in this prospectus. This
prospectus contains forward-looking statements that involve risks and
uncertainties. Our actual results may differ materially from those projected in
the forward-looking statements. Please see "Forward-Looking Statements and
Associated Risks" elsewhere in this prospectus. Our fiscal year ends on March
31.

Overview

  Data Return provides advanced Internet hosting services based on Microsoft
technologies. We provide these services to businesses seeking to outsource the
deployment, maintenance and support of their complex web sites. Our services
include providing, configuring, operating and maintaining the hardware,
software and network technologies necessary to implement and support these web
sites.

  The nature of our business is rapidly evolving and we have a limited
operating history. As a result, we believe that period-to-period comparisons of
our revenue and operating results, including our cost of revenue and other
operating expenses as a percentage of total revenue, are not meaningful and
should not be relied upon as indicators of future performance. We do not
believe that our historical growth rates are indicative of future results. See
"Risk Factors beginning on page 6 for a discussion of risks related to buying
shares of our common stock.

  Currently, we derive substantially all of our revenues from advanced hosting
services. We also derive a nominal amount of revenue from technical reviews and
the resale of software and other products. Currently, most of our advanced
hosting revenues are generated from recurring monthly fees. The remainder are
derived from one-time set-up fees for installation. Revenues are billed on a
monthly basis and are recognized as the service is performed. Most of our
customer agreements may be canceled on 30 days' notice.

  Our expenses are comprised of:

  .  cost of revenue, which consists primarily of compensation and related
     expenses for technical operations, bandwidth expenses, space in data
     centers and depreciation of equipment;

  .  general and administrative, which consists primarily of compensation and
     related expenses and occupancy costs;

  .  marketing and sales, which consists primarily of advertising and
     compensation and related expenses; and

  .  stock based compensation, which relates to employee options granted at
     prices less than fair market value.

  We have incurred significant losses since our inception and, as of June 30,
1999, had an accumulated deficit of approximately $2.1 million. We intend to
invest heavily in marketing and sales and the continued development of our
network infrastructure and technology. We expect to expand our operations and
workforce, including our network operations, technical support, sales,
marketing and administrative resources. In particular, we intend to expand our
existing inside sales force and create an outside sales force to develop new
sales channels and relationships. We expect to continue to incur substantial
losses for the foreseeable future. We may not be able to successfully execute
our expansion plans.

Comparison of three month periods ended June 30, 1998 and 1999

 Revenues

  Our revenues increased $946,700 to $1,227,500 for the three month period
ended June 30, 1999 from $280,800 for the three month period ended June 30,
1998. The increase was due to an increase in both the number of customers and
the average monthly revenue per customer. We increased our marketing and sales
personnel from two at June 30, 1998 to 12 at June 30, 1999.

 Cost of revenue

  Our cost of revenue increased $284,600 to $489,500, or 39.9% of revenue,
during the three month period ended June 30, 1999 from $204,900, or 73% of
revenue, during the three month period ended June 30, 1998. The increase in
cost of revenue over the two periods was due primarily to increases in
personnel and related costs, depreciation and bandwidth. Personnel and related
expenses increased approximately $128,500 to $225,200, or 46% of cost of
revenue, for the three month period ended June 30, 1999 from $96,700 for the
three month period ended June 30, 1998, as we increased our systems and
customer support personnel from 11 at June 30, 1998 to 25 at June 30, 1999.
Depreciation expense increased approximately $70,600 to $75,300 for the three
month period ended June 30, 1999 as we added approximately $1.4 million in
computer and related equipment since June 30, 1998. Our bandwidth expenses
increased $65,100 to approximately $145,200 for the three month period ended
June 30, 1999 from $80,100 for the three month period ended June 30, 1998, to
support our increased business activities. We expect our cost of revenue to
continue to increase in conjunction with the growth of our overall business.

 General and administrative

  General and administrative expense increased $652,400 to $865,600, or 70.5%
of revenue, during the three month period ended June 30, 1999 from $213,200, or
75.9% of revenue, for the three month period ended June 30, 1998. The increase
is primarily due to increases in personnel and related expenses and employee
recruiting fees. Personnel and related expenses increased $355,500 to $450,700,
or 52.1% of general and administrative expenses, for the three month period
ended June 30, 1999 from $95,200 for the three month period ended June 30,
1998. We increased our number of employees in general and administrative
functions

                                       23
<PAGE>

from five employees at June 30, 1998 to 13 employees at June 30, 1999.
Recruiting fees increased approximately $64,500 to $65,500 for the three month
period ended June 30, 1999 from $1,000 in the comparable period in 1998.

 Marketing and sales

  Marketing and sales expense increased $279,500 to $384,500, or 31.3% of
revenues, during the three month period ended June 30, 1999 from $105,000, or
37.4% of revenues, during the three month period ended June 30, 1998. The
increase was due primarily to an increase in marketing and sales personnel and
related expenses and increased advertising costs. Personnel and related
expenses increased $191,500 to $244,700, or 63.6% of marketing and sales
expense, from $53,200 for the three month period ended June 30, 1998.
Advertising costs increased $88,000 to $139,800 for the three month period
ended June 30, 1999 from $51,800 for the three month period ended June 30,
1998. We increased our marketing and sales personnel from two at June 30, 1998
to 12 at June 30, 1999. We intend to significantly increase our marketing and
sales expenditures during the remainder of fiscal 2000.

 Stock based compensation

  Deferred stock compensation was recorded in connection with the grant of
employee stock options below fair value. Amortization of stock based
compensation totaled $84,600 for the three month period ended June 30, 1998 and
$139,500 for the three month period ended June 30, 1999. The amortization of
stock based compensation is based on the vesting schedule of stock options held
by the Company's employees. We recorded deferred stock compensation of $874,100
during the three month period ended June 30, 1999.

 Other income (expense)

  Other income (expense) consists primarily of interest income on our cash
balances and interest expense on our outstanding notes payable and capital
lease obligations. Interest earned on our cash and cash equivalents increased
$16,700 to $22,900 for the three month period ended June 30, 1999 from $6,200
for the three month period ended June 30, 1998. This increase was due primarily
to the closing of private placements of equity securities in May 1998 and
February 1999, which resulted in larger cash balances available for investment.
During the three month period ended June 30, 1998 and 1999, we incurred
interest expense in the amount of $1,100 and $6,100, respectively.

 Income taxes

  No provision for federal income taxes has been recorded as we have incurred
net operating losses since our inception. We have recorded a valuation reserve
against all of our net deferred tax asset, which is primarily attributable to
net opening loss carryforwards, due to uncertainty that we will generate
sufficient taxable income during the carryforward period to realize the benefit
of our net deferred tax asset.

 Net losses

  Our net loss increased $313,000 to $634,800 for the three month period ended
June 30, 1999 from $321,800 for the three month period ended June 30, 1998.
This increase was due primarily to the growth of our business and the increase
in the number of personnel in all areas.

Comparison of the period from September 22, 1997 (inception) to March 31, 1998
and fiscal 1999

 Revenues

  Our revenues increased $1,552,900 to $1,889,000 during fiscal 1999 from
$336,100 for the period from September 22, 1997 (inception) to March 31, 1998.
This increase was primarily due to our generating revenues

                                       24
<PAGE>

for a full year during fiscal 1999 and the growth of our business activities.
Approximately 41% of our fiscal 1999 revenue was recognized in the fourth
quarter, due in part to the addition of two sales people in the third quarter.

 Cost of revenue

  Our cost of revenue increased $907,300 to $1,105,300, or 58.5% of revenue,
during fiscal 1999 from $198,000, or 58.9% of revenue, during the period from
September 22, 1997 (inception) to March 31, 1998. This increase was due
primarily to a full year of operations in fiscal 1999 and the growth of our
business and related expenses, including increasing our systems and customer
support personnel from six at March 31, 1998 to 20 at March 31, 1999. We expect
our cost of revenue to continue to increase in conjunction with the growth of
our overall business.

 General and administrative

  General and administrative expense increased $832,800 to $1,063,000, or 56.3%
of revenue, during fiscal 1999 from $230,200, or 68.5% of revenue, for the
period from September 22, 1997 (inception) to March 31, 1998. This increase was
due primarily to a full year of operations in fiscal 1999 and an increase in
the number of general and administrative personnel. We increased our number of
employees in this area from four employees at March 31, 1998 to eight employees
at March 31, 1999. We expect to significantly increase our general and
administrative expenditures. The decrease as a percentage of revenues was due
to revenues increasing at a more rapid rate than general and administrative
expenses.

 Marketing and sales

  Marketing and sales expense increased $623,800 to $662,800, or 35.1% of
revenues, during fiscal 1999 from $39,000, or 11.6% of revenues, during the
period from September 22, 1997 (inception) to March 31, 1998. This increase was
due primarily to a full year of operations in fiscal 1999 and an increase in
the number of marketing and sales personnel. We increased our marketing and
sales personnel from one to six in fiscal 1999. We intend to significantly
increase our marketing and sales expenditures during fiscal 2000.

 Stock based compensation

  Deferred stock compensation was recorded in connection with the grant of
employee stock options below fair value. Amortization of stock based
compensation totaled $61,300 for the period from September 22, 1997 (inception)
through March 31, 1998 and $348,800 for the year ended March 31, 1999. The
amortization of stock based compensation is based on the scheduled vesting of
stock options held by several employees. We recorded deferred stock
compensation of $1,277,000 in the period from September 22, 1997 (inception) to
March 31, 1998 and $328,000 during fiscal 1999.

 Other income (expense)

  Other income (expense) consists primarily of interest income on our cash
balances and interest expense on our outstanding notes payable and capital
lease obligations. Interest earned on our cash and cash equivalents increased
$17,700 to $19,900 during fiscal 1999 from $2,200 during the period from
September 22, 1997 (inception) to March 31, 1998. This increase was due
primarily to the closing of private placements of equity securities in May 1998
and February 1999, which resulted in cash balances available for investment.
During fiscal 1999, we incurred interest expense in the amount of $12,700.

 Income taxes

  No provision for federal income taxes has been recorded as we have incurred
net operating losses from inception through March 31, 1999. As of March 31,
1999, we had approximately $980,000 of federal net

                                       25
<PAGE>

operating loss carryforwards available to offset future taxable income which
expire in varying amounts beginning in 2013. We have recorded a valuation
reserve for all of our net deferred tax benefit for the period ended March 31,
1999 due to uncertainty that we will generate sufficient taxable income during
the carryforward period to realize the benefit of our net deferred tax asset.
In addition, after this offering, we may experience a change in control under
Section 382 of the Internal Revenue Code, which would limit our use of these
net operating loss carryforwards.

 Net losses

  Our net loss increased $1,093,000 to $1,284,000 during fiscal 1999 from
$191,000 for the period from September 22, 1997 (inception) to March 31, 1998.
This increase was due primarily to the growth of our business and the increases
in general and administrative and marketing and sales expenses.

Selected Quarterly Operating Results

  The following table sets forth certain unaudited statement of operations data
for each of the five quarters in the period ended June 30, 1999, as well as the
percentage of our revenue represented by each item. This data has been derived
from unaudited interim financial statements prepared on the same basis as the
audited financial statements contained in this prospectus. The interim
financial statements include all adjustments, consisting of normal recurring
adjustments, that we consider necessary for a fair presentation of such
information when read in conjunction with our financial statements and notes
thereto appearing elsewhere in this prospectus. The operating results for any
quarter should not be considered indicative of the results for any future
period.

  Revenues increased 30.2% during the quarter ended September 30, 1998, 27.6%
during the quarter ended December 31, 1998, 66.0% during the quarter ended
March 31, 1999 and 58.5% for the quarter ended June 30, 1999, as the size and
number of new customer orders rose significantly during each quarter. Cost of
revenue increased in each quarter, but decreased as a percentage of revenue.
General and administrative expense and marketing and sales expense generally
increased quarter over quarter primarily due to the addition of personnel as
our business increased.

Liquidity and Capital Resources

  We have historically financed our operations primarily through private
placements of equity. Our cash increased by approximately $2,272,900 during the
three months ended June 30, 1999 to $3,115,700. This net change is partially a
result of our raising approximately $3,275,000 from the sale of equity
securities offset by approximately $282,100 used to fund operating activities.
In addition, our investment in property and

                                       26
<PAGE>

equipment increased approximately $696,300 during the three month period ended
June 30, 1999. Installation of network infrastructure equipment and purchases
of furniture and equipment for new employees accounted for this increase.

  Total borrowings under our notes payable as of June 30, 1999 were
approximately $205,000. We intend to repay the amounts outstanding under these
agreements with a portion of the proceeds of this offering. Our credit
agreements and capital lease obligations contain no provisions that would limit
our future borrowing ability.

  Since June 30, 1999, we completed additional rounds of common stock financing
through the issuance of approximately 8,712 shares for gross cash proceeds of
$6.0 million. In addition, in July 1999, Level 3 purchased 7,260 shares of
common stock in exchange for a $5.0 million credit to be used against future
purchases of bandwidth in excess of our quarterly purchase commitment. In
addition, Microsoft has agreed to purchase $5.0 million of our common stock for
a per share price equal to the lesser of the midpoint of the lowest filing
range and the price to public.

  We believe that our current cash balances, proceeds from the private equity
financings closed since June 30, 1999 and the proceeds of this offering will be
sufficient to meet our working capital and capital expenditure requirements for
at least the next 12 months. If the offering is not consummated, we believe
that we could support operating and capital outlays for at least the next 12
months. Under our agreement with Level 3, we are required to purchase at least
$10.0 million of bandwidth and co-location services over the next five years.
Our quarterly commitment is $200,000 in the first year, $300,000 in the second
year, $400,000 in the third year, $600,000 in the fourth year and $1.0 million
in the fifth year of the agreement. We anticipate that further expansion of our
operations will cause us to incur negative cash flows on a short-term basis,
and therefore require us to use our cash and other liquid resources to support
our growth. Our operating and investing activities on a long-term basis may
require us to obtain additional equity or debt financing. We have no present
understandings, commitments or agreements with respect to any acquisition of
other businesses, products, services or technologies. However, we may evaluate
potential acquisitions of other businesses, products and technologies from time
to time. In order to consummate potential acquisitions, we may need additional
equity or debt financings in the future.

Recent Accounting Pronouncements

  On March 4, 1998, the Accounting Standards Executive Committee of the
American Institute of Certified Public Accountants (AICPA) issued Statement of
Position No. 98-1, "Accounting for the Costs of Computer Software Developed or
Obtained for Internal Use" (SOP 98-1). SOP 98-1 requires computer software
costs related to internal software that are incurred in the preliminary project
stage to be expensed as incurred. Once the capitalization criteria of SOP 98-1
have been met, external direct costs of materials and services consumed in
developing or obtaining internal-use computer software; payroll and payroll-
related costs for employees who are directly associated with and who devote
time to the internal-use computer software project (to the extent of the time
spent directly on the project); and interest costs incurred when developing
computer software for internal use should be capitalized. SOP 98-1 is effective
for financial statements for fiscal years beginning after December 15, 1998.
Accordingly, we will adopt SOP 98-1 in our financial statements for the year
ending March 31, 2000. We do not expect SOP 98-1 to have a material impact on
our financial statements.

  In April of 1998, the AICPA issued Statement of Position No. 98-5, "Reporting
on the Costs of Start-up Activities", which requires that costs related to such
activities be expensed as incurred. SOP 98-5 is effective for financial
statements for fiscal years beginning after December 15, 1998. Accordingly, we
will adopt SOP 98-5 in our financial statements for the year ending March 31,
2000. We do not expect SOP 98-5 to have a material impact on our financial
statements.

The Year 2000

 Impact of the Year 2000

  Currently, many computer and software products are coded to accept two-digit
entries in the date code field. These date code fields will need to accept
four-digit entries to distinguish 21st century dates from 20th century dates.
As a result, many companies' software and computer systems will need to be
upgraded or replaced to comply with Year 2000 requirements. Failure to make
such upgrades or replacements could result in system failure or erroneous
calculations, causing disruptions of operations, such as an inability to
process transactions, send invoices and engage in other normal business
activities. We recognize the need to ensure that our operations are not
adversely impacted by Year 2000 software and computer system failures. We are
not currently aware of any Year 2000 compliance problems relating to our
computer systems that would have a significant negative effect on our business,
operating results or financial condition.

 Project Plan and State of Readiness

  We have made a preliminary assessment of the Year 2000 readiness of our
computer systems and software, including the hardware and software that enable
us to provide and deliver our solutions. We plan to continue our Year 2000
readiness efforts by:

  .  testing our internal systems for Year 2000 compliance;

  .  contacting third-party suppliers, vendors and licensors of material
     hardware, software and systems that are both directly and indirectly
     related to the delivery of our solutions to our customers;

  .  assessing repair and replacement requirements;

  .  implementing repair and replacement requirements; and

  .  creating contingency plans for potential Year 2000 failures.

  We have initiated a four-phase plan for addressing Year 2000 issues with the
following estimated dates of completion:

<TABLE>
<CAPTION>
   Phase                                           Estimated Date of Completion
   -----                                           ----------------------------
   <C>  <S>                                        <C>
   I.   Preparation and Information Gathering....       April 30, 1999
   II.  Develop Project Plan.....................       August 31, 1999
   III. Execution of Project Plan................       September 30, 1999
   IV.  Full Compliance..........................       October 31, 1999
</TABLE>

  Some elements of the project plan are not dependent upon completion of other
elements. Therefore, we may execute elements of the project plan while there
may be outstanding tasks associated with other elements of the plan.

  Phase I - Preparation and Information Gathering. In this phase we determined
our Year 2000 risk. We inventoried our hardware and software and determined
what replacements and modifications were required for our systems and networks
to function properly after December 31, 1999. Upon review of hardware and
software data gathered during the inventory, we gathered Year 2000 compliance
information from our vendors via web site visits, phone calls or
correspondence. Although we have received information from the majority of our
key hardware and software component vendors that the products they supply to us
are currently Year 2000 compliant, we cannot be certain that any representation
made to us by any vendor is complete or accurate. In addition, we cannot be
sure that we have not overlooked critical systems. As we acquire new hardware
and software, we intend to use the same procedures to determine Year 2000
compliance.

  We primarily rely on four key hardware and software vendors: Microsoft,
Compaq, Cisco and Alteon. We have tested the Year 2000 compliance of the
products supplied by these vendors. For Microsoft products, the software is
considered Year 2000 compliant if it will function through the end of year
2035. We have identified remedial action that we need to perform on some of our
vendors' products. These upgrades are available, and we intend to install them
by September 30, 1999.

                                       28
<PAGE>

  Our internal systems are based upon the same key vendor hardware and software
product families described above. We have been advised by the vendor that our
customer relationship management package is Year 2000 compliant. In 1998, we
upgraded our internal accounting software with a package that, according to the
vendor, would make the system Year 2000 compliant. We are currently installing
a new phone system, and the vendor has informed us that it is Year 2000
compliant. We have contacted all of our significant vendors and third-party
providers to obtain assurance as to their Year 2000 compliance. All of these
vendors and providers have responded to our inquiries by directing us to their
Year 2000 compliance statements on their web sites. The web sites of our
significant vendors indicate that all software products are Year 2000 compliant
and all hardware is currently Year 2000 compliant or is being updated to become
Year 2000 compliant. We have not independently investigated these vendors' Year
2000 compliance.

  Phase II - Develop Project Plan. We have a project plan that identifies the
hardware and software replacements and/or modifications discovered during Phase
I. We have assigned departments and resources for completing the project plan
during this phase. While significant achievements were made in identifying
critical Year 2000 issues regarding information technology and non-information
technology related functions, we cannot assure you that critical equipment has
not been overlooked. Some Microsoft products may require additional service
packs and/or patches to make them Year 2000 compliant. In addition, some Compaq
servers have required revisions. We expect that hardware and software
revisions, such as applying updates, service packs and patches, will be
minimal.

  Phase III - Execution of Project Plan. We intend to accomplish the hardware
and software replacements and/or modifications identified in Phase I and
execute the project plan created in Phase II. During this phase we are
continuing to test and monitor Year 2000 compliance and the effect of any non-
compliance of our internal systems, vendors, service providers, clients and
their respective systems and monitor the effect of any non-compliance on our
business. We intend to re-evaluate the Year 2000 compliance of our hardware and
software components that have been replaced or modified. We intend to give
priority to those applications or processes posing the greatest threat of
failure and greatest potential impact on our business.

  While we believe that we have substantially completed our plan for achieving
Year 2000 compliance, the discovery of additional systems requiring remediation
could have a negative effect on the current plan and the resources required to
implement the plan.

  Phase IV - Full Compliance. We intend to be Year 2000 compliant by October
31, 1999 on all components critical to our business. However, we rely upon
hardware and software vendors and do not control the accuracy, timeliness or
completeness of their Year 2000 efforts. In addition, because our ability to
provide services depends on the networks and systems of other carriers, to the
extent that these networks and systems are adversely impacted by Year 2000
problems our ability to provide services to our customers may be adversely
impacted.

 Costs

  To date we have not incurred any material expenditures in connection with
identifying or evaluating Year 2000 compliance issues. We continue to collect
information and make the necessary revisions to our systems in an ongoing
effort to maintain Year 2000 compliance. We are not aware of any critical
third-party software application which requires replacement. In the event we
are required to make such a replacement, we do not anticipate that such
expenses will be substantial. However, such expenses, if higher than
anticipated, could harm our business and operating results.

 Risks and Contingencies

  Although we are not currently aware of any Year 2000 compliance problems
relating to our computer systems that would have a material negative impact on
our business, operating results or financial condition, we cannot assure you
that we will not discover Year 2000 compliance problems in our software and
systems that will require substantial revisions or expenditures or replacement.
In addition, we cannot be certain that we will not need to modify or replace
third-party software or hardware incorporated into our computer systems, which
could be time consuming and expensive. If an oversight were to occur by us or
one of our vendors and we or a

                                       29
<PAGE>

vendor failed to correct a material Year 2000 problem, we could experience an
interruption in or a failure of normal business activities or operations, such
as interruptions in our ability to provide services to our customers, an
inability to market our services to potential new customers and the loss of
customers. Any of these results could have a negative effect on our business.
Moreover, if we fail to adequately address Year 2000 compliance issues, it
could result in claims of mismanagement, misrepresentation or breach of
contract and related litigation, and any of these claims would likely be costly
and time-consuming to defend. In addition, we cannot assure you that government
agencies, utility companies, telecommunications companies, Internet service
providers, third-party service providers, hardware or software manufacturers
and others outside of our control will be Year 2000 compliant. The failure by
such entities to be Year 2000 compliant could result in systemic failures
beyond our control. Prolonged Internet, telecommunications, electrical or other
failures could decrease the demand for our services and the use of the Internet
or prevent users from accessing the web sites of our customers. This would
materially harm our business.

  Year 2000 issues may also impact the interaction of our systems with the
software, hardware or systems of our suppliers. Furthermore, our ability to
provide services to our customers depends on the networks and systems of other
carriers. Any failures or problems experienced by the networks and systems of
those carriers may adversely impact our ability to provide services to our
customers. In addition, because we rely on our web site as a marketing and
sales tool, any failures or problems affecting the Internet or our web site
could hinder our marketing and sales efforts. We are not evaluating the Year
2000 compliance of our customers' web sites.

  Each of the following events must be included in a consideration of the worst
case scenario, which is an overall failure of the Internet, the
telecommunications infrastructure and the electrical grid: widespread failure
of communications carriers, public utilities, unavailability of transit for
staff, suppliers and clients; disruption of our ability to gain access to, and
continue operating in, office buildings and other facilities; the failure of
significant portions of our critical computer systems and their respective
components, including both internal business systems and systems controlling
operational facilities such as electrical generation, transmission and
distribution systems; and the failure of outside entities' systems, including
systems related to banking and finance.

  We provide our hosting services through a combination of skilled labor,
hardware and software products and services from major vendors within the
computer and telecommunications industries. Because our ability to provide our
services depends on the performance of each of these components, the Year 2000
problem has introduced many risks and uncertainties, and the Year 2000
compliance of many of these components, such as the supply chain, utility
companies and our customers' systems, is beyond our control and in some case
beyond our ability to test. Because of these uncertainties, we are unable to
determine whether the consequences of Year 2000 failures will have a material
impact on our business.

  If we cannot operate effectively after December 31, 1999, we could, among
other things, face substantial claims by customers, including for lost profits,
or loss of revenue due to service interruptions, inability to fulfill
contractual obligations or bill customers accurately and on a timely basis, and
increased expenses associated with litigation, stabilization of operations
following critical system failures and the execution of contingency plans. We
could also experience an inability by customers and others to pay us on a
timely basis or at all. Under these circumstances, the adverse effects,
although not quantifiable at this time, would be material.

  We are continuing to gather information and evaluate the possible impact of
the Year 2000 on our business and to develop contingency plans to implement if
any of our systems are not Year 2000 compliant.

Quantitative and Qualitative Disclosures About Market Risk

  All our customer contracts are currently denominated in United States
dollars, and we do not currently invest in derivative financial instruments.
However, we invest our excess cash balances in cash equivalents and are
therefore subject to market risk related to changes in interest rates. We
believe, but cannot be certain, that the effect on our financial position,
results of operation and cash flows of any reasonably likely changes in
interest rates would not be material.

                                    BUSINESS

Our Company

  Data Return provides advanced Microsoft-based Internet hosting services to
businesses, web site developers and other organizations. Our advanced Microsoft
hosting services enable our customers to establish and maintain sophisticated
e-commerce and other applications through which they can conduct transactions
and manage information on a worldwide basis over the Internet. Our hosting
services, which are based on the Microsoft platform, provide support for
software such as Windows NT, Internet Information Server, Active Server Pages,
SQL Server and Site Server Commerce Edition. According to IDC, Microsoft
Windows NT will be the key engine for growth within the worldwide server market
and Windows NT's market share will grow at a compound annual growth rate of 25%
from 1998 to 2003.

  We provide our services to companies across many industries located primarily
in North America and Europe. We also have a small but growing customer base in
South America, Asia, Africa and Australia. As of August 31, 1999, we hosted
over 1,600 web sites for more than 800 customers.

  Our advanced hosting services are designed for customers deploying
sophisticated, high-end Internet applications that require a professionally-
managed environment incorporating high performance network access, advanced
system monitoring and technical support in highly secure, fault-tolerant
facilities. We believe that we are well positioned to take advantage of the
rapidly growing demand for advanced hosting which is being driven by the growth
in user access to the Internet, e-commerce and the outsourcing of web services.

  We were incorporated in August 1997 by three former Microsoft product support
engineers. We believe that our exclusive focus on the Microsoft platform and
our approach to offering pre-packaged hosting services have been the major
contributors to our growth. We believe the following are among the key factors
that have distinguished our company and our offerings and that will continue to
drive our growth:

  .  a full range of pre-packaged hosting services supported by advanced
     managed services for fixed monthly prices;

  .  high availability and high performance clustering solutions for web
     servers and database servers;

  .  an advanced and secure network architecture that has delivered faster
     network performance compared to the single fastest backbone provider;

  .  automated work flows and service deployment processes;

  .  avoiding competition with software developers and systems integrators;
     and

  .  a commitment to serving members of the Microsoft developer community,
     who are valuable sources of customer referrals.

  Level 3 and Compaq have invested in our company, and Microsoft has agreed to
purchase shares of our common stock. We believe our relationships with these
companies enhance our credibility with potential customers and provide us with
early access to new products, superior technical services, training and new
business development opportunities. In July 1999, we entered into a five-year
agreement with Level 3 under which:

  .  Level 3 has designated us as a preferred provider of advanced Microsoft
     hosting services;

  .  we will train Level 3's sales personnel to identify and refer potential
     customers to us on a commission basis;

<PAGE>

  .  we are entitled to offer our services from the 17 existing and all
     future Level 3 gateways in the U.S. enabling us, we believe, to avoid
     the significant costs of building our own data centers;

  .  Level 3 will provide assistance as needed in the installation and
     support of our equipment located in their gateways; and

  .  Level 3 has acquired shares of our common stock in exchange for $5.0
     million in credit for future bandwidth purchases in excess of our
     purchase commitment.

  Also in July 1999, we entered into a three-year agreement with Compaq. Under
that agreement, Compaq has agreed to include Data Return in any program under
which it approves for recommendation to its customers a specified group of
application service providers. Although Compaq is not required to develop such
a program, it will include us in any such program that it does establish at the
highest level for which we qualify. In addition, Compaq has purchased shares of
our common stock for a purchase price of $3.0 million.

  In September 1999, we entered into an agreement with Microsoft under which we
will license proprietary installation tools for third-party hosted applications
to Microsoft and train Microsoft's employees and customers in the use of those
tools. Under that agreement, Microsoft will provide technical consulting and
writing services, and we will co-market the tools with Microsoft. Microsoft has
also agreed to invest $5.0 million in our common stock.

Industry Background

 Growth of the Internet and Electronic Commerce

  The market for advanced hosting services has been driven by the growth of the
Internet. The Internet has emerged as a new medium for communicating,
exchanging information and transacting business. IDC projects that the number
of Internet users will grow from approximately 159 million at the end of 1998
to over 410 million at the end of 2002. Forrester Research projects that during
the next five years U.S. online business-to-business trade will exceed $1.0
trillion. Forrester Research also projects that e-commerce will generate over
$3.2 trillion in worldwide revenue by 2003. We believe businesses and other
organizations will attempt to take advantage of this growth by establishing new
web sites or upgrading existing web sites. We further believe that many of
these sites, particularly those used for electronic commerce, will be
increasingly complex and have high traffic volume requirements.

 Outsourcing of Web Hosting

  As businesses attempt to take advantage of the revenue potential presented by
the growth of the Internet and e-commerce by establishing web sites that
interact with customers, vendors and employees, we believe that they will
increasingly outsource the hosting of their web sites. To support e-commerce
applications, these sites must be capable of reliably and securely completing
financial transactions. The process of establishing a web site includes:

  .  specification of site requirements, including the associated business
     work flows and processes;

  .  development and testing of software consistent with the specifications;

  .  acquisition and installation of hardware, software and network access in
     a controlled environment; and

  .  physical implementation of the web site onto the Internet.

  Once a web site is implemented, it requires monitoring, maintenance and
management provided by knowledgeable personnel. While some businesses currently
choose to operate and maintain their web sites in-house, we believe that many
businesses, even those with relatively large and sophisticated information
technology departments, will find outsourcing the hosting of their web sites
attractive due to the following factors:

  .  rapid changes in the various complex technologies involved;

  .  difficulty of deploying highly sophisticated web applications;

                                       32
<PAGE>

  .  challenge of hiring and retaining experienced and qualified personnel;

  .  lack of the infrastructure needed to deploy, expand, upgrade and
     maintain essential applications on the Internet around the clock; and

  .  potential cost savings associated with personnel and system
     infrastructure requirements.

  We believe that the trend toward outsourcing the hosting of web sites will
continue as businesses increase the complexity of their web sites and require
greater interactivity for end users. We believe that these web sites will
increasingly be based on Microsoft Internet technologies. IDC projects that
Windows NT will be the key engine for growth within the worldwide server market
and Windows NT's market share will grow at a compound annual growth rate of 25%
from 1998 to 2003.

 The Outsourcing of Packaged Application Hosting

  For many of the above reasons, companies are seeking to outsource the
management of important software applications that can be accessed over the
Internet. We believe that many of these applications will also be based on
Microsoft Internet technologies. These applications govern business processes
such as e-mail, sales force automation, human resource management, decision
support, supply chain management, core financials and overall enterprise
resource management. We believe that the potential benefits of outsourcing
these applications include significant improvements in application availability
and reduced ongoing management costs. According to IDC, information systems
outsourcing, which includes data center, client/server and help desk
applications, is the fastest growing segment of the market, and spending in
this area will increase at a 12.2% compound annual growth rate through 2003.
Further, IDC projects that spending on worldwide outsourcing services will
increase from $99.0 billion in 1998 to more than $151.0 billion by 2003.

Our Market Opportunity

 The Advanced Hosting Opportunity

  Advanced hosting is distinguished from basic hosting by requirements for:

  .  more bandwidth;

  .  more complex system architectures, including support for extranets and
     intranets;

  .  more complex software technologies;

  .  a higher level of technical expertise to support these complex systems;
     and

  .  higher system performance and reliability.

  Advanced hosting is used to support highly interactive web sites on which
real-time transactions and full-featured e-commerce applications are
implemented. These sites provide users with the ability to interact with
databases and require a high level of expertise for implementation and
maintenance support. For higher volumes of user traffic and transactions,
multiple servers may be required.

  As e-commerce becomes increasingly important to businesses worldwide, we
believe that many businesses will outsource the hosting and maintenance of
their high-volume, transactional web sites. Further, beyond e-commerce, we
believe that the hosting market will be driven by a demand for the outsourcing
of other enterprise-wide, business unit and information technology department
functions. According to Forrester Research, the hosting market will grow from
$0.9 billion in 1998 to $14.6 billion in 2003, a 76% compound annual growth
rate.

 Hosting on the Microsoft Platform

  We believe that the market for advanced hosting on the Microsoft platform
offers a greater opportunity than the market for hosting on other platforms,
such as Unix. Microsoft is the dominant provider of operating systems for
personal computers. We believe that many developers are writing web
applications for the Microsoft platform because of previous experience gained
in the Microsoft architecture, including experience with Basic, Visual Basic
and Active Server Pages. According to Microsoft, more than two million
developers participate in Microsoft's Developer Network and Site Builder
Network programs. We believe that, as businesses demand applications that are
capable of operating on the Internet, developers are increasingly responding by
producing Microsoft-based solutions that require hosting on Microsoft
platforms. For example, IDC reports that Microsoft 32-bit Windows offerings
have the leading position in terms of operating environment license revenues
and license shipments for client operating environments. Additionally, we
believe the momentum toward the Microsoft platform is driven by market demand
for shortened development cycles, lower development costs and lower operating
costs.

Our Solution

  Data Return is an advanced hosting provider dedicated to delivering scalable,
reliable and high performance hosting services on the Microsoft platform. By
combining our expertise in managing Microsoft-based Internet technologies, a
scalable deployment architecture and high performance content delivery, we have
developed a family of services that addresses a wide range of customer needs.

 Advanced Managed Services

  Managing the deployment of business-critical web applications requires an in-
depth understanding of all underlying software, hardware and network
technologies. We use our expertise in Microsoft technologies to provide
management services for our customers' hosting needs which include:

  .  consultation and recommendations on standardized system architecture;

  .  installation, configuration and stress testing of hardware and software;

  .  ongoing maintenance of hardware and software including content back-ups
     and system upgrades;

  .  a broad array of system and network monitoring and reporting services
     provided 24 hours a day; and

  .  advanced technical support designed to respond to both simple and
     complex system issues.

 Scalable Deployment Architecture

  Our customers require system architecture that is flexible and can be
expanded over time to meet increasing demand. Data Return has developed a
scalable deployment architecture for the Microsoft platform that enables
customers to begin with cost effective shared solutions and then migrate to
dedicated services and high-end multi-server clustered solutions as their site
traffic grows. The flexibility of this architecture allows us to offer a wide
range of hosting solutions to our customers.

 High Performance Content Delivery

  Overall application performance is an essential component to deploying an
Internet-based application successfully. There are many factors that contribute
to overall performance including the configuration and architecture for
hardware, software and Internet access. Our private networking architecture
bypasses the congested public exchange points, such as the Metropolitan Area
Exchanges and Network Access Points, increasing speed and reliability. By
taking a comprehensive approach to optimizing application performance, we
delivered network performance faster on average, during the period from August
16, 1999 through the date of this prospectus in the United States compared to
the single fastest backbone provider as measured by Keynote Systems.

 Pre-Packaged Solutions for Advanced Hosting

  We have standardized our services into packages with defined pricing and
feature sets. We believe these pre-packaged solutions simplify the sales
process and customer support compared to co-location. Co-location arrangements
typically involve a vendor supplying space for the server and Internet
connections and the customer being responsible for defining and implementing
the deployment architecture. Our pre-packaged solutions enable our customers to
outsource these responsibilities to us for their Internet, extranet or intranet
applications.

Our Strategy

  Our goal is to take advantage of the growth in Internet usage, e-commerce and
the outsourcing of hosting services to become the leading provider of advanced
hosting services. Our strategy for accomplishing this goal contains the
following key elements:

  Maintain Focus on Advanced Hosting on the Microsoft Platform. We intend to
maintain our exclusive focus on Microsoft-based advanced hosting, which enables
us to concentrate our expertise. We believe that we are better able to attract
customers because we have targeted the Microsoft platform, which we believe is
significantly underserved. By focusing on one platform, we are not required to
duplicate systems and operations costs which would be necessary to support
multiple platforms. In addition, by focusing exclusively on advanced hosting
and not engaging in web site development or systems integration services
ourselves, we are able to maintain close relationships with developers and
systems integrators, who serve as a valuable source of referrals.

  Offer a Full Range of Highly Scalable Advanced Hosting Services. We attract
customers by offering a full range of Microsoft-based hosting services from
shared and dedicated services to complex, clustered solutions. We intend to
continue working with Microsoft and other technology partners to remain at the
forefront of packaging new technologies into advanced hosting services. We
believe that our advanced hosting customers view their web applications as an
important part of their business strategy and are seeking a growing number of
services. We target larger customers with substantial and complex requirements.
However, our broad range of service offerings also attracts customers with
lower volume requirements who can migrate to more powerful service offerings as
their needs evolve. We believe that our broad range of service offerings
attracts customers who are likely to be long-term customers.

  Maintain Non-Capital Intensive Business Model. We deploy our hosting services
within third-party data centers to avoid the high capital expenditures
associated with building our own data centers. Rather than investing in data
centers and other capital intensive assets, we invest in internally developed
and third-party software and other tools. We believe this allows us to increase
customer satisfaction by providing better service and increases our financial
flexibility by reducing fixed costs. Specifically, we are able to add value and
generate a competitive advantage by continuing to develop best practices,
standardized service offerings and automated processes that improve operational
efficiency.

  Enhance Our Marketing and Sales Programs. Through the packaging of our
offerings, we believe we have substantially reduced the complexity of
purchasing advanced hosting services. We intend to substantially increase our
advertising efforts to further promote awareness of the Data Return brand and
our advanced Microsoft-based hosting offerings. To date, our sales have been
made through our inside sales force, which has focused on responding to leads
and other inquiries generated from advertising and referrals. In parallel with
the expansion of our inside sales force, we intend to establish an outside
sales force to proactively seek larger

                                       35
<PAGE>

opportunities. Additionally, we intend to train Level 3's sales force, as
contemplated by our agreement with Level 3, and to further formalize our
partner programs with developers and systems integrators to identify and refer
their leads for advanced Microsoft-based hosting services to Data Return.

  Capitalize on Key Relationships. We have relationships with Level 3, Compaq,
Microsoft and Alteon that we believe provide us with early access to new
products, superior technical services, training and new business development
opportunities. In some cases, these partners have provided us with direct and
indirect funding. We believe that our association with industry leaders
enhances our credibility with potential customers. We intend to strengthen our
existing relationships and to seek additional strategic arrangements when
appropriate.

  Provide Superior Customer Service. We intend to continue to provide high-
quality customer service by maintaining a high level of technological expertise
in our customer support and sales organizations and by proactively monitoring
the performance of our customers' web sites. We believe that our
standardization of hardware and software solutions, which results in efficient
training, documentation and overall logistics and operations, allows us to
deliver high-quality customer service. We intend to continue leveraging our
relationships with Compaq, Microsoft and Alteon to receive the technical
training and support necessary to provide high levels of customer support
during both installation and ongoing maintenance.

  Expand Our Data Center Presence. The servers we use in offering our hosting
services are located in data centers, which are secure facilities with multiple
Internet connections, multiple power sources and other features designed to
minimize the possibility of service interruptions. We currently operate from
data centers in Fort Worth and Dallas, and our agreement with Level 3 allows us
to establish data centers in the 17 current and all future Level 3 gateways
located in the U.S. We intend to offer services from Level 3's data centers in
San Francisco and London in the second half of 1999. We also intend to provide
services through Level 3's network, which is currently planned to be composed
of local networks in approximately 50 cities, over the next five years.
Additionally, our relationship with Level 3 will provide us with access to
bandwidth and personnel to assist in the installation and implementation of our
equipment in their gateways. These capabilities position us to offer nationwide
points of presence for shared, dedicated, clustered and geographically
dispersed clustered hosting services.

  Expand into New Hosting Markets. We believe that the execution of the above
elements of our strategy will enable us to address new hosting markets as they
develop. In particular, we believe that we are positioned to expand into the
emerging application service provider market without significant changes to our
operations or business model. We believe that our Microsoft-based hosting
services will be a desirable platform for electronic distribution in the
emerging software rental market. Additionally, we believe that software
companies whose products either draw upon Microsoft technologies or whose
products typically interface to the large installed base of Microsoft systems
will find our hosting services attractive. We have recently begun offering
hosting services for Microsoft Exchange, which is an advanced messaging
service.

Our Services

  We have made an extensive effort to package our hosting services into
standardized, definable product offerings. Our services are designed to be
comprehensive in terms of feature sets and to address customers' outsourcing
needs for a wide variety of requirements, including:

  .  customers accessing public web sites on the Internet;

  .  employees accessing private web sites through intranets; and

  .  partners and other designated user groups accessing private or public
     web sites through extranets.

                                       36

 Offerings

  Our advanced Microsoft hosting platform allows us to support the Internet,
intranets and extranets for both commercially developed applications and custom
developed applications. To address this wide variety of customer requirements,
Data Return has developed three distinct categories within our service family.
During the three month period ended June 30, 1999, excluding set-up fees, 50.6%
of our revenues was derived from our shared services, 38.2% was derived from
dedicated services and 11.2% was from clustered hosting services.

    Shared Hosting Services. Shared hosting services are entry level service
  plans designed for customers with complex requirements but relatively low
  volumes of traffic. We have designed our shared hosting packages to
  minimize the cost for customers by providing these services on a server
  shared by multiple customers. Our service plans include many standard
  features and options for database support, commerce support, media services
  and extensive e-mail support.

    Dedicated Hosting Services. Dedicated hosting services are designed for
  customers with more complex requirements, high traffic volumes and who are
  seeking greater control over management of their servers. Our dedicated
  service plans provide each customer with its own server. These service
  plans offer a number of advantages to our customers in addition to those
  received in our shared hosting packages, including:

    .  improved service reliability and content delivery by limiting each
       server to a single developer environment;

    .  greater flexibility in configuration of the specific server
       environment; and

    .  complete server control by providing customers with console-level
       server access.

  We offer several dedicated service options that range from entry-level web
  servers to high performance, multi-processor database servers.

    Clustered Hosting Services. For customers that deploy e-commerce enabled
  or other business-critical applications or expect very high user traffic
  volumes, we have developed a family of clustered hosting services,
  including geographically dispersed clusters. Our clustered service plans
  distribute content and functionality across multiple servers, which allows
  our customers' applications to scale beyond a single server. Additionally,
  our clustering services are designed to allow our customers' business-
  critical applications to continue operating in the event a server fails.
  These services are designed to provide significantly enhanced system
  performance and system reliability for application and database services.
  These services require specialized hardware and software which we include
  in our pre-packaged solutions. We believe that customers will increasingly
  require the type of services supported by clustered solutions and therefore
  our sales volumes in this category will increase.

                                       37

 Pricing

  We bill for our services on a monthly basis and for a one-time initial setup
fee at the time the server is configured. In addition to our pre-packaged
product offerings, we also work with customers to develop custom configurations
that are based on our standard hosting architecture. Our product offerings and
prices for new installations as of August 31, 1999 are generally described in
the table below.

</TABLE>

  To further simplify the purchasing process for our customers, all service
plans, including features and pricing, are described on our web site. This
enables our customers to evaluate the various service offerings before
contacting one of our sales representatives, which in turn can shorten our
selling cycle, reduce our customer acquisition costs and ultimately enhance
customer satisfaction by making readily available the necessary technical and
business information for choosing the appropriate service level. We intend to
continually upgrade our web site to provide more product information and
enhanced purchasing capabilities for our existing and prospective customers.

Customers

  We provide hosting services to end user businesses, web site development
firms and other organizations. Our customers are located primarily in North
America and Europe. We also have a small but growing customer base in South
America, Asia, Africa and Australia. As of August 31, 1999, we hosted over
1,600 web sites for more than 650 customers ranging from small- and medium-
sized businesses to Fortune 500 companies. Some of our more widely known
customers at that time were:

Key Relationships

 Level 3

  We entered into a five-year relationship with Level 3 in July 1999 and are
currently Level 3's only preferred provider of advanced hosting services for
the Microsoft platform. Our strategic relationship with Level 3 allows us to
leverage our advanced hosting and managed application services with their sales
force and U.S. data center infrastructure. Level 3 provides us with segregated
rack space capacity and environment controls for up to 6,000 servers in its
Dallas gateway and access to the 17 existing and all future U.S. Level 3
gateways. In addition, Level 3 will provide personnel at these data centers to
install equipment and assist with support as necessary for us to deliver
service in these facilities. This reduces the number of implementation
engineers we require to deploy and support solutions for our customers in these
locations. We believe that these benefits, coupled with geographic and network
proximity to our customers, will become a marketing and technological advantage
in the immediate future. Under our agreement with Level 3 we have agreed to
purchase most of our bandwidth and co-location requirements from Level 3 to the
extent they meet our then-current performance and capacity requirements. We
have also made a purchase commitment to Level 3 increasing from $800,000 in the
first year to a total of $4.0 million in the fifth year for a total minimum
commitment for the term of the contract of $10.0 million. Level 3 can terminate
this agreement for a default by us which is not cured within 30 days of notice
or a change of control that results in Data Return being owned by a competitor
of Level 3.

  We will train Level 3's sales personnel to identify potential customers for
our advanced hosting services and refer them to us. Level 3's sales personnel
will be paid a commission based on a percentage of the first month's monthly
recurring revenue on all leads that become our customers. As we train Level 3's
sales force at a particular data center, we intend to deploy our own outside
sales force in that region to work with Level 3 to

                                       39
<PAGE>

develop and close joint sales leads. To date, our growth has been driven
primarily by our inside sales force. We believe that the lead generation of
Level 3's sales force, combined with our future outside sales force, positions
us to substantially increase our rate of growth. Level 3 has acquired shares of
our common stock in exchange for $5.0 million in credit for future bandwidth
purchases in excess of our quarterly purchase commitment.

 Compaq

  We use Compaq servers exclusively to provide the hardware platform for our
advanced hosting services. Our relationship provides direct contact with
product development engineers and marketing management at multiple levels
within the Compaq organization. We recently entered into a three-year agreement
with Compaq under which we will purchase from Compaq the lesser of 2,000
servers or the number of servers reasonably necessary to adequately operate our
business consistent with our business plan. We are required to purchase these
servers only if Compaq provides financing for the servers on competitive terms,
if the price, performance and quality of the Compaq servers is reasonably
satisfactory to us and if Compaq commits to deliver these servers on the
schedule we request. Also as part of our strategic relationship with Compaq,
Compaq has agreed to include Data Return in any program under which it approves
for recommendation to its customers a specified group of application service
providers. Although Compaq is not required to develop such a program, it will
include us in any such program that it does establish at the highest level for
which we qualify. Compaq has also purchased $5.0 million of our common stock.

  We work collaboratively with the Compaq engineering and product marketing
teams on the Distributed Internet Server Array (DISA) architecture to develop
enhanced offerings for multiple server configurations (clustered web and SQL
server solutions). We are also currently working on a Compaq co-funded print
campaign featuring our use of Compaq servers in a clustered environment. We are
also a Compaq Solutions Alliance SELECT Partner. The SELECT Partner designation
is the highest attainable level in this program and provides us with a wide
variety of information, tools, services and networking opportunities.

 Microsoft

  We recently entered into a licensing agreement with Microsoft. Under this
agreement we will license proprietary installation tools for third-party hosted
applications to Microsoft. We will also train Microsoft's employees and
customers in the use of those tools. Microsoft will, in return, provide us with
technical consulting and writing services during the development of the tools.
Microsoft has also agreed to co-market the tools with us in a manner that is
mutually acceptable to both parties. Microsoft has also agreed to purchase $5.0
million of our common stock.

  We are recognized by Microsoft as one of the leading providers of advanced
hosting services on the Microsoft platform. We have received the Microsoft
Advanced Hosting Partner and Application Service Provider Partner designations
and have achieved a high level of integration at all levels within Microsoft.
We believe that one of our key competitive advantages is the level of customer
service and support that we can provide as a result of this enhanced
relationship. However, we do not have an agreement with Microsoft to provide
this level of support and integration or to continue to confer these
certifications and designations. Microsoft could discontinue its relationship
with us at any time. Our expertise in deploying and managing the Microsoft
Internet platform is also an important factor in our business relationship with
Microsoft. Our status with Microsoft provides us with the following:

  .  access to a local, field-based Microsoft representative;

  .  a corporate-based business development manager;

  .  designated points of contact in the customer units and product groups;

  .  escalated technical support;

  .  advance product notification;

  .  advance product releases;

                                       40
<PAGE>

  .  participation in beta programs;

  .  joint marketing programs; and

  .  leads and new business development opportunities generated by Microsoft.

  Following are some of the Microsoft designations, certifications and related
agreements that Data Return currently has:

  .  We are one of eight Microsoft Advanced Hosting Partners. This status
     signifies our ability to provide database integration, full back-end
     transaction processing and advanced content management.

  .  We are one of ten designated Microsoft Application Service Providers,
     defined by Microsoft as being able to provide superior infrastructure,
     service and performance for hosted applications on the Microsoft
     platform.

  .  We are one of 11 Microsoft Commerce Hosting Services providers. This
     signifies our ability to provide customers with an advanced e-commerce
     hosting infrastructure.

  .  We are a Microsoft Windows Media Service Provider. This status signifies
     our ability to deploy and maintain audio and video streaming media
     solutions.

  .  We participate in rapid deployment programs for various Microsoft
     products. As such, we are responsible for providing feedback on
     Microsoft products in the advanced hosting and managed application
     markets prior to release, and by doing so we are able to provide
     services and gain expertise on these products before the general market.

  .  We are a Microsoft Certified Solution Provider at the Partner level. The
     Partner designation is the highest attainable level in this program. We
     believe this designation provides us with preferred access to a broad
     range of Microsoft resources and is a distinguishing factor for
     development firms and systems integrators looking to identify sources
     for advanced hosting.

  .  We have acquired Microsoft Premier Support, which provides the most
     direct, fastest and highest formal escalation path for resolution of
     product-related problems within Microsoft, including a technical account
     manager at Microsoft who is responsible for ensuring that Microsoft
     product support provides timely and accurate resolutions to problems we
     or our customers may encounter.

 Alteon

  Alteon manufactures state-of-the-art switching products capable of supporting
millions of concurrent connections with load balancing and fail-over for
clustered server configurations. We believe we were the first commercial
installation of the Alteon server switching platform for the Microsoft Internet
platform. Our Chairman and Chief Executive Officer, Sunny Vanderbeck, is an
advisory board member of Alteon. The advisory board assists management in
product, marketing and distribution planning. Additionally, we are using the
Alteon WebOS application programming interface to enhance clustered solutions.
These enhanced clustered solutions deliver real-time performance data to the
hardware platforms, providing increased functionality, reliability and
scalability in high-volume and complex deployments.

Marketing and Sales

  Our marketing strategy has initially been focused on our product packaging.
We have made an extensive effort to package our hosting services in
standardized, definable product offerings that are competitive in terms of
features, functions and prices. We have made our services easy to purchase by
presenting these packages in detail on our web site, including all set-up and
monthly charges. We believe that this packaging and standardization shortens
our selling cycle and enhances customer satisfaction by making available to
decision makers the technical and business information necessary to choose a
service level.

                                       41
<PAGE>

  We intend to substantially increase our marketing expenditures to help build
awareness of our brand and to further generate sales. We have a customer
tracking system that provides us with timely reports as to which marketing
activities are producing the greatest return, which enables us to better
allocate our marketing resources. We currently have a diversified marketing
effort for demand generation. Primarily we market through advertising in
magazines targeted at developers and information service professionals. We also
advertise online, through direct mail and at trade shows and conferences.
Additionally, many web sites of our customers and partners have direct links to
our web site. We intend to increase our spending in all of these areas, and in
particular focus on direct mail because we believe it will significantly help
our outside sales force in their business generation efforts.

  Our sales have predominantly been generated by developer and customer
referrals. We believe that a distinguishing characteristic of our company is
that we do not provide application development services and, therefore, do not
compete with any of our development focused customers. We believe that as more
development companies make the decision to outsource the hosting of their
clients' applications, Data Return will be an attractive alternative to hosting
providers that also offer development services.

  Our inside sales force responds to inquiries, which typically have been
generated by advertising and referrals from customers, strategic partners and
developers. We intend to significantly increase our inside sales force during
the second half of 1999 to respond to the inquiries that we believe will be
generated by our increased marketing efforts. Concurrently, we are developing
an outside sales force to proactively seek potential customers. Each outside
salesperson's territory will include one or more Level 3 U.S. gateways. The
outside sales force will work in conjunction with Level 3's sales force to
provide training and ongoing sales support. Both our inside and outside sales
force will be responsible for following up on leads generated by Level 3's
sales force. We intend to continue to add outside salespeople as Level 3 builds
out its U.S. gateways.

  We have recently implemented a sales incentive program that we believe has
increased sales productivity and enhanced pre-sales customer service. Our sales
force is paid a commission for each sale that they complete based upon the
customer's first month of recurring revenue. To encourage our sales force to
pursue long-term revenue generating business, we adjust the commission paid to
the sales person if the customer does not use our service for a minimum period
of time. In addition to paying commissions to our inside and outside sales
personnel, we will pay commissions to Level 3's sales force for all sales based
on leads they refer to us. We believe this commission structure will create a
high level of cooperation in the field between Data Return's and Level 3's
sales forces.

Customer Support

  We believe a critical element of our customer service is providing a high
level of technical expertise within both our customer support and systems
organizations. Our technical support engineers are expected to be proficient in
at least:

  . one major network operating system;

  . two applications from our supported product list; and

  . either one programming language or one database application.

  Further, we require all of our support and systems technicians to become
Microsoft Certified Systems Engineers or Microsoft Certified Professionals.

  All systems are monitored and maintained on a 24 hours a day, seven days a
week, or 24x7, basis. We provide standard customer support from 9AM-8PM Central
time Monday through Friday and 12PM-5PM Saturday via both telephone and
electronic request forms. We provide business-critical customer support on a
24x7 basis. We strive to respond within 15 minutes or less for business-
critical problems. Response times for all severity levels are published on our
support web site and are prioritized according to our customers' assessment of
severity levels.

                                       42
<PAGE>

  Our customer care system provides support personnel with timely online
information regarding the status of all set-up and support incidents.
Additionally, support personnel have access to information regarding the sales
history and current sales activities for each customer account. This
integration of support and sales systems enables us to allocate resources with
a full knowledge of both new business opportunities and any customer support
issues. We believe that this system will support substantially greater
economies of scale and quality of service.

Infrastructure

  We use a platform which is comprised mostly of Internet-related software
products running on Microsoft's Windows NT operating system and Compaq servers.
We use Alteon clustering switches along with Cisco switches and routers to
connect our servers to the Internet. Using our standard platform, we have
gained efficiency and effectiveness in terms of training, documentation, spare
parts, overall support and system performance. We also maintain some legacy
hosting services running on the Unix platform. In addition, our customers
benefit from our ability to support application level services such as SQL
Server, Active Server Pages and Site Server Commerce Edition. Specifically, our
infrastructure consists of the following key elements:

  . highly secure, carrier-class data centers;

  . a scalable server platform;

  . automated deployment processes;

  . comprehensive and centralized monitoring and systems management;

  . fault-tolerant clustered servers; and

  . an advanced, high performance network.

 Highly Secure, Carrier-Class Data Centers

  Our first data center is located in a facility in downtown Fort Worth. The
facility is a Bellcore standard Class A facility, which is an industry term
indicating that the facility has redundant systems to prevent down-time caused
by system failures at the facility. Security for the data center is provided
with a 24x7 armed guard and entry restriction via card key access. Power to the
building is provided by redundant connections from separate transformers. The
data center is also equipped with FM200 gas fire suppressant systems,
environmental control systems and redundant networking hardware.

  In January 1999, we established our second data center within Level 3's
Dallas gateway. The Level 3 facility, which is also a Bellcore standard Class A
facility, provides us with environmental resources similar to the Fort Worth
data center, but on a much larger scale. In addition to providing greater
capacity for server racks and associated environmental support, the Level 3
facility provides us with access to Level 3's worldwide IP network. The Level 3
relationship provides us with access to the 17 current and all future gateways
in the U.S. This provides us with the ability to expand not only bandwidth
resources, but also the ability to open new data centers in major cities across
the U.S. on relatively short notice and with relatively little investment by
us. All of Level 3's highly secure, carrier-class facilities are designed for
scalability and include advanced security features that may include biometric
palm readers, video monitoring and card key access, and fault-tolerant power
systems, such as multiple power grids, facilities-based AC/DC battery back-up
and diesel generators. We intend to offer services from Level 3's London,
England and San Francisco data centers in the second half of 1999.

 A Scalable Server Platform

  Our standard platform for service delivery uses Compaq servers. These servers
generally run the Windows NT or Windows 2000 operating system, along with
various application software such as Microsoft SQL Server

                                       43
<PAGE>

or Microsoft Internet Information server. Compaq's Distributed Internet Server
Array (DISA) architecture leverages the clustering and load balancing features
of Windows NT Server, Enterprise Edition with Internet Information Server. This
architecture enables us to support scalable, highly-available Internet-enabled
applications. In addition, our standard hardware configuration allows us to
maintain standby hardware for use in the event of hardware failure. While these
servers use a standard hardware and software platform, we apply our expertise
in their configuration and tuning.

 Automated Deployment Processes

  We configure and test our hardware and software through the use of both
commercially available and internally built tools. The software installation
process consists of a series of unattended scripts and batch files providing a
fast, consistent and repeatable configuration. As the server is provisioned
with user accounts, web sites and file transfer protocol sites, the automated
script also tests each step to verify that the server is functioning correctly.
We also manually test the installation process to further evaluate the quality
and integrity of the installation.

 Comprehensive and Centralized Monitoring and Systems Management

  We combine commercial tools and internally built applications to provide
comprehensive and centralized monitoring, analysis and reporting of
application, service and hardware performance on a 24x7 basis. Proactive
hardware and application monitoring maximizes service performance levels and
reliability. Systems administration and management is remotely performed using
an interface which encrypts all client-server communication with a 64-bit
encryption algorithm for added security. Additionally, we offer a customer
control panel, which provides a standard user interface that allows them to
perform the most commonly performed web site administrative tasks. The customer
control panel also allows the customer to electronically submit support
requests to our service and support group for the more advanced administrative
tasks and support issues. This approach to monitoring and systems management
allows us to use the same methodologies and processes across all of our data
centers regardless of geographic location.

 Fault-Tolerant Clusters

  We currently offer two levels of clustered solutions: level one clustered
application services and level two clustered application and database services.
Level one clustered solutions utilize products from Alteon to provide high
availability and traffic load balancing for application resources, such as web
servers and application servers. In the event of an application server failure,
all traffic is redirected from the failed server to the remaining available
application servers to protect against service outage. Level two clustered
solutions provide enhanced application availability by adding clustered
database services, which are well suited for the clustering of transactional
data resources including Microsoft SQL Server. These solutions are based on
Fibre Channel storage systems from Compaq and the Microsoft Cluster Service. We
also offer geographically dispersed solutions which allows us to load balance
and fail-over applications between data centers.

 Advanced High Performance Network

  We have based our network hardware on Cisco and Alteon technologies. Our
highly secure network consists of multiple, diverse connections to the Internet
which currently provide us with local access to seven leading backbone
providers. These multiple connections allow us to increase both performance and
reliability by routing traffic over private connections, bypassing congested
public exchange points such as the Metropolitan Area Exchanges and Network
Access Points. By taking a comprehensive approach to optimizing application
performance, we have delivered network performance faster in the United States
on average compared to the single fastest backbone provider as measured by
Keynote Systems over the period from August 16, 1999 through the date of this
prospectus. In addition to increased performance, our network

                                       44
<PAGE>

architecture reduces our dependency on any one network provider, increasing
network availability for our customers. Further, we have our own IP addresses,
which reduces our dependence on specific network providers or other third
parties. Our network security solutions include firewalls, encryption
techniques, virtual private networks and other security technologies and
techniques. To date in 1999, we are one of the top three issuers of Verisign
certificates, which enable secure e-commerce.

Competition

  The markets in which we operate are highly competitive, and competition is
increasing because few apparent substantial barriers to entry exist in the
Internet hosting market. We expect that we will face competition from existing
competitors as well as new market entrants in the future. The primary
competitive factors in our market are:

  .technical expertise in developing advanced web hosting solutions;

  .quality of service, including network capability, scalability, reliability
  and functionality;

  .customer service and support;

  .variety of services and products offered;

  .price;

  .brand name recognition;

  .Internet system engineering and technical expertise;

  .timing of introductions of value-added services and products;

  .network security;

  .financial resources; and

  .conformity with industry standards.

  Our current and potential competitors vary by size, product offering and by
geographic region and may elect to partner with each other or with focused
companies like us to deliver service on the Microsoft platform. They include:

  .  Microsoft advanced hosting providers, such as Digex, MCI WorldCom
     (including UUNET), GTE Internetworking and USWeb/CKS Group;

  .  web and application hosting service providers, such as Interliant,
     Navisite and USinternetworking;

  .  application-specific hosting service providers, such as Critical Path;

  .  co-location providers, such as AboveNet, Exodus, Digital Island and
     Frontier GlobalCenter;

  .  local, regional and international Internet service providers, such as
     AppliedTheory, Concentric, Globix, MindSpring, Verio and PSINet;

  .  local, regional and international telecommunications companies, such as
     AT&T, British Telecommunications, Cable & Wireless, Telecom Italia,
     Nippon Telegraph and Telephone, Qwest and the regional Bell operating
     companies such as Bell Atlantic and U S WEST;

  .  systems integrators and large information technology outsourcing
     companies, such as IBM, EDS, Oracle, Andersen Consulting,
     PricewaterhouseCoopers and others;

  .multimedia hosting companies, such as broadcast.com; and

  .other hardware, software and technology companies.

                                       45

  We believe that our expertise and exclusive focus on the advanced hosting
segment of the Internet services market enables us to differentiate ourselves
from our competitors. We also believe that our expertise and focus on
Microsoft-based Internet technologies, our customer support and our ability to
maintain a service delivery infrastructure that is designed to parallel or
surpass the performance provided by Internet backbone providers and other
telecommunications carriers will further differentiate us from our competitors.
Additionally, our marketing and sales methodologies are focused on enabling
customers to easily select and deploy solutions based on packaged service
offerings, which can shorten our selling cycle, reduce our customer acquisition
costs and ultimately enhance customer satisfaction.

Intellectual Property Rights

  We rely on a combination of copyright, trademark, service mark and trade
secret laws and contractual restrictions to establish and protect certain
proprietary rights in our data, applications and services. We are in the
process of filing Federal registrations for the trademark "Data Return," as
well as other service and trademarks which incorporate the Data Return name.

Government Regulation

  We are not currently subject to direct federal, state or local government
regulation, other than regulations applicable to businesses generally. There is
currently only a small body of laws and regulations directly applicable to
access to e-commerce on the Internet.

  Congress recently enacted the "Digital Millennium Copyright Act," which
became effective in October 1998. The Digital Millennium Copyright Act provides
a limitation on liability of online service providers for copyright
infringement for transmitting, routing or providing connections, transient
storage, caching or storage at the direction of a user, if the service provider
had no knowledge or awareness that the transmitted or stored material was
infringing and meets certain other conditions. Since this law is new and does
not apply outside of the United States, we are unsure of how it will be applied
to limit any liability we may face in the future for any possible copyright
infringement or copyright-related issues. This new law also requires service
providers to follow "notice and take-down" procedures and to meet other
conditions in order to be able to take advantage of the limitation on
liability. We have not yet implemented such procedures, met such conditions or
evaluated the cost of complying with them. However, our customers are subject
to an acceptable use policy which prohibits them from transmitting, storing or
distributing material on or through any of our services which, in our sole
judgment is (1) in violation of any United States local, state or federal law
or regulation, (2) fraudulent online marketing or sales practices or (3)
fraudulent customer information, including identification and payment
information. Although this policy is designed to promote the security,
reliability and privacy of our systems and network, we cannot be certain that
our policy will accomplish this goal or effectively limit our liability.

  Despite enactment of the Digital Millennium Copyright Act, the law relating
to the liability of online services companies and Internet access providers for
information carried on or disseminated through their networks remains largely
unsettled. It is possible claims could be made against online services
companies and Internet access providers under both United States and foreign
law for defamation, obscenity, negligence, copyright or trademark infringement,
or other theories based on the nature and content of the materials disseminated
through their networks. Several private lawsuits seeking to impose such
liability upon online services companies and Internet access providers are
currently pending.

  Although sections of the Communications Decency Act of 1996 that proposed to
impose criminal penalties on anyone distributing indecent material to minors
over the Internet were held to be unconstitutional by the U.S. Supreme Court,
similar laws may be proposed, adopted and upheld. The nature of future
legislation and the manner in which it may be interpreted and enforced cannot
be fully determined and, therefore, legislation similar to the Communications
Decency Act could subject us and/or our customers to potential liability, which

                                       46
<PAGE>

in turn could harm our business. The adoption of any of these types of laws or
regulations might decrease the growth of the Internet, which in turn could
decrease the demand for our services or increase our cost of doing business or
in some other manner harm our business.

  Due to the increasing popularity and use of the Internet, it is likely that a
number of additional laws and regulations may be adopted at the federal, state
and local levels with respect to the Internet, covering issues, such as user
privacy, freedom of expression, pricing, characteristics and quality of
products and services, taxation, advertising, intellectual property rights,
information security, access fees and the convergence of traditional
telecommunications services with Internet communications. The adoption of any
of these laws or regulations might decrease the growth of the Internet, which
in turn could decrease the demand for our services or increase the cost of
doing business or in some other manner harm our business, results of operations
or financial condition. In addition, applicability to the Internet of existing
laws governing issues such as property ownership, copyrights and other
intellectual property issues, taxation, libel, obscenity and personal privacy
is uncertain. The vast majority of such laws were adopted prior to the advent
of the Internet and related technologies and, as a result, do not contemplate
or address the unique issues of the Internet and related technologies.

Employees

  As of August 31, 1999, we had 79 employees. None of our employees are covered
by collective bargaining agreements. We believe that our relations with our
employees are good.

Facilities

  Our corporate headquarters are currently located in Irving, Texas and consist
of approximately 23,000 square feet of office space that is leased until
October 31, 2001. We also have an office in Arlington, Texas, consisting of
5,000 square feet of office space that is leased until March 31, 2000.

Legal Proceedings

  We do not believe that we are subject to any pending or threatened legal
proceedings.

Director Compensation

  Our directors receive no remuneration for serving on our board of directors.

Board Composition

  We currently have five authorized directors. In accordance with the terms of
our restated articles of incorporation, the terms of office of the directors
are divided into three classes:

  .  Class I, whose term will expire at the annual meeting of shareholders to
     be held in 2000;

  .  Class II, whose term will expire at the annual meeting of shareholders
     to be held in 2001; and

  .  Class III, whose term will expire at the annual meeting of shareholders
     to be held in 2002.

  Currently, the Class I directors are Jason A. Lochhead and Nathan Landow, the
Class II director is Michelle R. Chambers and the Class III director is Sunny
C. Vanderbeck. T. Geir Ramleth will serve as a Class II director upon
completion of this offering. As part of an agreement with Level 3, they are
entitled to nominate one of their employees to serve on our board of directors.
Mr. Vanderbeck, Ms. Chambers and Mr. Lochhead have agreed to vote for Level 3's
nominee. This agreement terminates upon a public offering of our common stock.
Level 3 has not exercised its right to nominate a person to serve on our board
of directors. At each annual meeting of shareholders after the initial
classification or special meeting in lieu thereof, the successors to directors
whose terms will then expire will be elected to serve from the time of election
and qualification until the third annual meeting following election or special
meeting held in lieu thereof. The authorized number of directors may be changed
only by resolution of the board of directors or a super-majority vote of the
shareholders. Any additional directorships resulting from an increase in the
number of directors will be distributed among the three classes so that, as
nearly as possible, each class will consist of one third of the directors. This
classification of the board of directors may have the effect of delaying or
preventing changes in control or management of Data Return.

Stock Option Plans

  1998 Stock Option Plan. Our 1998 Stock Option Plan authorizes the issuance of
up to 3,308,700 shares of our common stock. As of September 1, 1999, we had
granted options to purchase an aggregate of 3,223,696 shares of our common
stock to employees and directors under this plan with a weighted average
exercise price of $0.56 per share. After the completion of this offering, no
further options will be granted under this plan.

  The board of directors, or a board committee, has the power to determine the
terms of the options, including the exercise price of the options, the number
of shares subject to each option, the exercisability thereof, and the form of
consideration payable on such exercise, provided that the exercise price must
be at least 100% of fair market value. Incentive stock options granted to any
holder of 10% or more of the combined voting power of all classes of stock must
have an exercise price of not less than 110% of fair market value and be
exercisable for a term of no more than five years.

  1999 Long-Term Incentive Plan. Our 1999 Long-Term Incentive Plan was adopted
by our board of directors and shareholders and became effective in July 1999 as
a successor plan to our 1998 Plan. Up to 3,228,000 shares of common stock may
be issued under the 1999 Plan.

  The 1999 Plan provides for the discretionary grant of incentive stock
options, within the meaning of Section 422 of the Internal Revenue Code of
1986, to employees and for the grant of nonstatutory stock options, stock
appreciation rights, performance awards, dividend equivalents, stock payments
and restricted stock to employees and consultants. The 1999 Plan provides that
we cannot issue incentive stock options after June 2009.

  The 1999 Plan may be administered by the board or a board committee. The
administrator has the power to determine the terms of the options or other
awards granted, including the exercise price of the options or other awards,
the number of shares subject to each option or other award (up to 269,000
shares per year per participant), the exercisability thereof and the form of
consideration payable upon exercise. In addition, the administrator has the
authority to amend, suspend or terminate the 1999 Plan, provided that no such
action may affect any share of common stock previously issued and sold or any
option previously granted under the 1999 Plan without the consent of the
holder.

  The exercise price of all incentive stock options granted under the 1999 Plan
must be at least equal to the fair market value of the common stock on the date
of grant. The exercise price of nonstatutory stock options and other awards
granted under the 1999 Plan is determined by the administrator, but the
exercise price of nonstatutory stock options must be at least 50% of the fair
market value of the common stock on the date of grant. With respect to any
participant who owns stock possessing more than 10% of the voting power of all
classes of our outstanding capital stock, the exercise price of any incentive
stock option granted must be at least equal to 110% of the fair market value on
the grant date and the term of such incentive stock option must not exceed five
years. The term of all other options granted under the 1999 Plan may not exceed
ten years.

  Options and other awards granted under the 1999 Plan are generally not
transferable by the optionee. Options granted under the 1999 Plan must
generally be exercised within three months after the end of the optionee's
status as an employee, director or consultant, or within one year after such
optionee's termination by disability or death, respectively, but in no event
later than the expiration of the option's term.

  The 1999 Plan provides that in the event of a change of control of Data
Return all options and other awards shall be assumed or a substitute option or
award issued by the acquiring company unless the board determines in its sole
discretion to accelerate vesting or remove any restrictions.

Compensation Committee Interlocks and Insider Participation

  We currently have no separate compensation or stock option committee or other
board committee performing equivalent functions to determine compensation for
executive officers. These functions are

                                       52
<PAGE>

performed by our board of directors, which includes Mr. Vanderbeck and Ms.
Chambers. Within 90 days after we complete this offering, we intend to
establish a compensation committee that will be composed of Ms. Chambers and
two independent directors. No interlocking relationship exists between any
member of our board or our compensation committee and any member of the board
of directors or compensation committee of any other company, and no such
interlocking relationship has existed in the past.

Employment Agreements

  Mr. Vanderbeck, Ms. Chambers, Mr. Bowles, Mr. Brewer, Mr. Lochhead  and Mr.
Walker have employment agreements expiring on June 30, 2002. These agreements
provide for:

  .  set base salaries; and

  .  incentive bonuses determined by the compensation committee or board of
     directors.

  Each of these executives has agreed not to compete with us during the term of
the agreement and for two years after resignation or termination for cause or
for one year after a termination without cause or any resignation or
termination following a change of control. The employment agreements define
"cause" as an employee committing an immoral crime, materially breaching the
employment agreement or failing to obey written directions of a senior
corporate executive. A "change of control" will be deemed to occur if a
substantial portion of our ownership changes or the constitution of the board
changes during any 15-month period without the approval of our board of
directors or shareholders. If there has not been a change in control, the
agreements provide for the payment of salary for 12 months after any
termination by Data Return other than for cause. Further, if the termination
follows a change of control and is not voluntary, it will be made in a lump sum
equal to the following items, or in the case of Mr. Vanderbeck and Mr. Chambers
three times the following items:

  .  the highest annualized base salary earned during the employee's
     employment with us;

  .  two times the employee's largest bonus during the last two years;

  .  any unpaid expense, reimbursement or accrued but unpaid salary or
     benefit; and

  .  the estimated cost of insurance coverage for the next 12 months.

If the termination is following a change of control and is voluntary, the base
salary component of these severance payments will, in the case of Mr.
Vanderbeck, Ms. Chambers and Mr. Walker, equal 75% and, in the case of Mr.
Bowles, Mr. Brewer and Mr. Lochhead equal 25%, of the highest annualized base
salary earned during the employee's employment with us.

  In addition, upon a change of control, all outstanding options of Mr.
Vanderbeck, Ms. Chambers  and Mr. Walker will vest. That number of the
outstanding options of Mr. Bowles, Mr. Brewer and Mr. Lochhead that would have
vested upon their next annual vesting date will immediately vest upon a change
of control, and, if they are terminated within 24 months of a change of
control, all of their options will immediately vest.

  We also have employment agreements with Mr. Shiff, Mr. Garber and Mr.
Steitle. Mr. Shiff's agreement expires on December 31, 2002. His agreement
provides for a set base salary plus deferred salary and a fixed performance
bonus. Mr. Shiff's agreement provides for the payment of all accrued salary and
bonus upon his termination by Data Return. Upon a change of control or an
initial public offering, all of Mr. Shiff's outstanding options will vest
immediately. Mr. Shiff has agreed not to compete with us during the term of his
agreement and for one year after his termination.

  Mr. Garber's agreement expires on March 31, 2004. His agreement provides for
a set base salary plus commissions. Upon a termination of his employment by
Data Return without cause, Mr. Garber is entitled to the payment of salary for
12 months and the right to participate in benefit plans and exercise his
outstanding

                                       53
<PAGE>

options for 12 months. Upon a public offering or change of control, 50% of Mr.
Garber's outstanding options vest immediately and the remaining 50% vest one
year later. If Mr. Garber is terminated following a change of control, he is
entitled to 12 months of salary and all of his outstanding options immediately
vest. Mr Garber has agreed not to compete with us during the term of the
agreement and for one year after resignation or termination for cause.

  Mr. Steitle's agreement expired on May 3, 1999 and was automatically renewed
for a one year period. His agreement will continue to be renewed automatically
for one year periods unless terminated by either party upon notice at least 15
days prior to a renewal date. Mr. Steitle is entitled to a set base salary.
Upon termination other than for cause, Mr. Steitle is entitled to his accrued
salary. Upon a change of control, or upon an initial public offering or if Mr.
Vanderbeck and Ms. Chambers cease to be executive officers, all of Mr.
Steitle's options immediately vest. Mr. Steitle has agreed not to compete with
us during the term of his agreement and for one year after his agreement.

                             PRINCIPAL SHAREHOLDERS

  The following table sets forth information regarding the beneficial ownership
of our common stock as of September 1, 1999, based on 27,755,958 shares
outstanding on that date, and as adjusted to reflect the issuance of additional
shares of common stock in this offering, by the following individuals or
groups:

  .  each person or entity who is known by us to own beneficially more than
     5% of our common stock;

  .  each director;

  .  each named executive officer; and

  .  all of our executive officers and directors as a group.

  Beneficial ownership is determined in accordance with the rules of the
Securities and Exchange Commission. In general, a person who has voting power
and/or investment power with respect to securities is treated as a beneficial
owner of those securities. Shares subject to options, warrants or rights
currently exercisable or exercisable within 60 days of the date of this
prospectus are considered beneficially owned by the person holding such
options, warrants or rights. Unless indicated otherwise, we believe that the
persons named in the table below have sole voting and investment power with
respect to the shares shown.

  Unless otherwise indicated, the address for each 5% shareholder listed in the
table is c/o Data Return Corporation, 222 West Las Colinas Boulevard, Suite
450, Irving, Texas 75039. Except as otherwise indicated, and subject to
applicable community property laws, the persons named in the table have sole
voting and investment power with respect to all shares of common stock held by
them.

  To the extent that any shares are issued upon exercise of options or other
rights to acquire capital stock that are presently outstanding or granted in
the future or reserved for future issuance under stock plans, there will be
further dilution to new public investors.

23, 1999 with Level 3, the credit can be applied to bandwidth services in
excess of the minimum purchase under the Strategic Marketing and Sales
Agreement beginning in 2001. We have a right to repurchase the stock in the
event that Level 3 fails to fulfill its obligations under the Service Credit
Agreement or Level 3 does not honor orders submitted by us under the Strategic
Marketing and Sales Agreement. The number of shares subject to this repurchase
right will be reduced pro rata in each quarter of calendar year 2001 by the
greater of the credit applied or 25% of the total shares. In the event that
Level 3 defaults under the Service Credit Agreement and fails to cure within 30
days, Level 3 is required to pay us $750,000 ratably reduced based on the
amount of bandwidth credit used. Level 3 is entitled to one demand and
unlimited "piggyback" registration rights.

  Also on July 23, 1999, Data Return, Sunny C. Vanderbeck, Michelle R. Chambers
and Jason A. Lochhead entered into a Voting Agreement with Level 3. Under that
agreement, Level 3 is entitled to nominate one of its employees to serve on our
board of directors. Mr. Vanderbeck, Ms. Chambers and Mr. Lochhead have agreed
to vote for Level 3's nominee. The Voting Agreement terminates upon the
completion of a public offering of our common stock.

  On July 29, 1999, we sold 1,171,764 shares of our common stock to Compaq for
an aggregate purchase price of $3.0 million. Compaq is entitled to one demand
and unlimited "piggyback" registration rights. Compaq also has a right of first
refusal that does not include this offering and that terminates upon completion
of this offering. Also on July 23, 1999, we entered into an ASP and Server
Agreement with Compaq. Under that agreement, we have agreed for a three-year
period to purchase from Compaq the lesser of 2,000 servers or the number of
servers reasonably necessary to adequately operate our business plan. Our
requirement to purchase these servers is contingent upon Compaq providing
financing for the servers on competitive terms, upon the price, performance and
quality of the Compaq servers being reasonably satisfactory to us and upon
Compaq's commitment to deliver these servers on the schedule we request. Under
the ASP and Server Agreement, Compaq has agreed to include Data Return in any
program under which it approves for recommendation to its customers a specified
group of application service providers. Although Compaq is not required to
develop such a program, it will include us in any such program that it does
establish at the highest level for which we qualify.

  On September 3, 1999, we agreed to sell $5.0 million of our common stock for
a per share purchase price equal to the lesser of the midpoint of the lowest
filing range and the price to public. Microsoft will also acquire a warrant to
purchase $3.75 million of our common stock at the same per share purchase
price. Based on the

                                       56
<PAGE>


current filing range, Microsoft would acquire 416,667 shares under the stock
purchase agreement and the warrant would entitle Microsoft to acquire an
additional 312,500 shares at an exercise price of $12.00 per share. Microsoft
is entitled to one demand and unlimited "piggyback" registration rights.
Microsoft also has a right of first refusal that does not include this offering
and that terminates upon completion of this offering. This transaction will
close the earlier of the day after the pricing of this offering and December
12, 1999. In addition, on September 3, 1999, we entered into a five-year
Development, License and Co-Marketing Agreement with Microsoft to grant a non-
exclusive perpetual license to proprietary installation tools for third-party
hosted applications to Microsoft. We will also train Microsoft's employees and
customers in the use of those tools. Microsoft has the sole right to terminate
the agreement if we fail to deliver the tools on a timely basis or if we fail
to correct any errors in the tools on a timely basis. Also as part of the
agreement, Microsoft will provide up to one hundred hours of technical
consulting and writing services during the development of the tools.

                          DESCRIPTION OF CAPITAL STOCK

  The following summaries highlight the material provisions of our articles of
incorporation and bylaws, as amended. Copies of our articles and bylaws are
available from us upon request. See "Where You Can Find More Information."

Authorized Capital Stock

  Our authorized capital stock consists of 100,000,000 shares of common stock,
par value $.001 per share, and 20,000,000 shares of preferred stock, par value
$.001 per share. As of September 1, 1999, there were 27,755,958 shares of
common stock issued and outstanding, and no shares of preferred stock issued
and outstanding. No holder of any shares of our stock has any preemptive or
preferential right to acquire or subscribe for any unissued shares of any class
of stock or any authorized securities convertible into or carrying any right,
option or warrant to subscribe for or acquire shares of any class of stock.

Common Stock

  Each share of common stock has identical rights and privileges in every
respect. The holders of our common stock are entitled to vote upon all matters
submitted to a vote of our shareholders and are entitled to one vote for each
share of common stock held.

  Subject to the prior rights and preferences, if any, applicable to shares of
preferred stock, the holders of common stock are entitled to receive such
dividends, payable in cash, stock or otherwise, as may be declared by our board
out of any funds legally available for the payment of dividends.

  If we voluntarily or involuntarily liquidate, dissolve or wind-up, the
holders of common stock will be entitled to receive after distribution in full
of the preferential amounts, if any, to be distributed to the holders of
preferred stock, all of the remaining assets available for distribution ratably
in proportion to the number of shares of common stock held by them. Holders of
common stock have no preferences or any preemptive, conversion or exchange
rights.

Preferred Stock

  Our board is authorized to provide for the issuance of shares of preferred
stock in one or more series, and to fix for each series voting rights, if any,
designations, preferences and relative, participating, optional or other
special rights and such qualifications, limitations or restrictions as provided
in a resolution or resolutions adopted by the board. The board may authorize
the issuance of shares of preferred stock with terms and conditions which could
discourage a takeover or other transaction that holders of some or a majority
of shares of common stock might believe to be in their best interests or in
which holders of common stock might receive a premium for their shares over the
then market price.

Warrants

  Upon the earlier of the day after the pricing of this offering and December
11, we will have outstanding a warrant to purchase $3.75 million of our common
stock at a per share exercise price equal to the lesser of the midpoint of the
lowest filing range and the price to public. This warrant will expire five
years after the date of its issuance. Based on the current filing range, this
warrant would entitle Microsoft to acquire 312,500 shares at an exercise price
of $12.00 per share.

Preferred Stock Purchase Rights

  We intend to adopt a shareholder rights plan and declare a dividend of
preferred stock purchase rights before this offering is consummated. These
rights will entitle our shareholders to rights to acquire additional

                                       58
<PAGE>

shares of our common stock when a third party acquires 15% of our common stock
or commences or announces its intent to commence a tender offer for at least
15% of our common stock. The final terms of these rights will be contained in a
rights agreement between us and the rights agent we appoint.

Transfer Agent and Registrar

  The transfer agent and registrar for our common stock is ChaseMellon
Shareholder Services, LLC.

Anti-Takeover Effects of Provisions of our Articles of Incorporation and Texas
Law

 Restated Articles of Incorporation and Bylaws

  Pursuant to our articles, the board may issue additional shares of common
stock or establish one or more series of preferred stock having the number of
shares, designations, relative voting rights, dividend rates, liquidation and
other rights, preferences and limitations that the board may decide without
shareholder approval. Any additional issuance of common stock or designation of
rights, preferences, privileges and limitations with respect to preferred stock
could have the effect of impeding or discouraging the acquisition of control of
Data Return by means of a merger, tender offer, proxy contest or otherwise
(including a transaction in which the shareholders would receive a premium over
the market price for their shares) and thereby protects the continuity of our
management. Specifically, if in the due exercise of its fiduciary obligations,
the board were to determine that a takeover proposal was not in our best
interest, shares could be issued by the board without shareholder approval in
one or more transactions that might prevent or render more difficult or costly
the completion of the takeover by:

  .  diluting the voting or other rights of the proposed acquiror or
     insurgent shareholder group;

  .  putting a substantial voting block in institutional or other hands that
     might undertake to support the incumbent board; or

  .  effecting an acquisition that might complicate or preclude the takeover.

  Our bylaws provide that the board is divided into three classes of one or two
directors each, with each class elected for three-year terms expiring in
successive years. Our articles also allow the board to set the number of
directors in the bylaws with no minimum or maximum number of directors
required. The articles specifically deny cumulative voting in the election of
directors. This could delay or prevent a tender offer or takeover attempt that
a shareholder might consider to be in his or her best interest, including
attempts that might result in a premium over the market price for the shares
held by the shareholders.

  Our articles and bylaws provide that special meetings of shareholders
generally can be called only by the president or the board or by holders of at
least 50% of our voting stock and provide for an advance notice procedure for
the nomination, other than by or at the direction of the board or a committee
of the board, of candidates for election as directors as well as for other
shareholder proposals to be considered at annual meetings of shareholders. In
general, we must receive notice of intent to nominate a director or make a
proposal at such meetings no less than 90 days before the meeting. The notice
must contain certain information concerning the person to be nominated or the
matters to be brought before the meeting and concerning the shareholder
submitting the proposal. These provisions of the bylaws:

  .  may preclude a nomination for the election of directors or preclude the
     conduct of business at a particular meeting if the proper procedures are
     not followed; and

  .  may discourage or deter a third party from conducting a solicitation of
     proxies to elect its own directors or otherwise attempting to obtain
     control of Data Return, even if the conduct of such solicitation or
     attempt might be beneficial to us and our shareholders.

 Texas Takeover Statute

  Subsequent to this offering, we will be subject to Part Thirteen of the Texas
Business Corporation Act. Subject to certain exceptions, Part Thirteen
prohibits a Texas corporation which is an issuing public corporation from
engaging in any business combination with any affiliated shareholder for a
period of three years following the date that such shareholder became an
affiliated shareholder, unless:

  .  prior to such date, the board of directors of the corporation approved
     either the business combination or the transaction that resulted in the
     shareholder becoming an affiliated shareholder; or

  .  the business combination is approved by at least two-thirds of the
     outstanding voting shares that are not beneficially owned by the
     affiliated shareholder or an affiliate or associate of the affiliated
     shareholder at a meeting of shareholders called not less than six months
     after the affiliated shareholder's share acquisition date.

  In general, Part Thirteen defines an affiliated shareholder as any entity or
person beneficially owning 20% or more of the outstanding voting stock of the
issuing public corporation and any entity or person affiliated with or
controlling or controlled by such entity or person. Part Thirteen defines a
business combination to include, among other similar types of transactions, any
merger, share exchange or conversion of an issuing public corporation involving
an affiliated shareholder.

  Part Thirteen may have the effect of inhibiting a non-negotiated merger or
other business combination involving Data Return.

                        SHARES ELIGIBLE FOR FUTURE SALE

  Prior to this offering, there has been no public market for our common stock.
We cannot predict what effect, if any, market sales of shares or the
availability of shares for sale will have on the market price of our common
stock prevailing from time to time. Nevertheless, sales of substantial amounts
of common stock in the public market, or the perception that such sales could
occur, could adversely affect the market price of the common stock and could
impair our future ability to raise capital through the sale of our equity
securities. Upon the closing of this offering, we will have a total of
34,422,625 shares of common stock outstanding, assuming no exercise of the
underwriters' over-allotment option and no exercise of any other stock options.
Of the outstanding 34,422,625 shares, the 6,250,000 shares being sold in this
offering will be freely tradable, except that any shares held by our
"affiliates" may only be sold in compliance with the limitations described
below. The remaining 28,172,625 shares of common stock will be "restricted
securities" that may be sold in the public market only if they are registered
under the Securities Act or if they qualify for an exemption from registration
under Rules 144, 144(k) or 701 promulgated under the Securities Act. Subject to
the lock-up agreements described below and the provisions of Rules 144, 144(k)
and 701, additional shares will become available for sale in the public market
as follows:

                                               eligible for resale under Rules 144 and 701
                    --                         and are not subject to lock-up agreements.

                                               After 180 days from the date of this
                                               prospectus. These additional shares are
                                               eligible for resale under Rules 144 and 701
                20,551,600                     upon release of lock-up agreements.
</TABLE>

Rule 144

  In general, under Rule 144, a person, or persons whose shares are required to
be aggregated, including an affiliate, who has beneficially owned shares for at
least one year is entitled to sell, within any three-month period commencing 90
days after the date of this prospectus, a number of shares that does not exceed
the greater of (i) 1% of the then-outstanding shares of common stock, which
will be approximately 344,227 shares immediately after this offering, or (ii)
the average weekly trading volume of the common stock during the four calendar
weeks preceding the date on which notice of that sale is filed.

Rule 144(k)

  Under Rule 144(k), a person who is not considered an affiliate at any time
during the 90 days preceding a sale and who has beneficially owned the shares
proposed to be sold for at least two years is entitled to sell such shares
under Rule 144(k) without regard to the volume limitations described above.

Stock Options

  Following the closing of this offering, we intend to file a registration
statement to register for resale the shares of common stock available for
issuance under our stock option plans. Accordingly, shares issued under those
plans will become eligible for resale in the public market from time to time,
subject to the lock-up agreements described below and, in the case of
affiliates, the volume limitations of Rule 144 described above.

As of the date of this prospectus, options to purchase a total of 6,532,396
shares of common stock are outstanding under our stock option plans.

and the underwriters named below, who are represented by Bear, Stearns & Co.

shares of common stock at the public offering price less the underwriting

</TABLE>

  The underwriting agreement provides that the obligations of the underwriters
to purchase and accept delivery of the shares included in this offering are
subject to approval of legal matters by their counsel and to customary
conditions, including the effectiveness of the registration statement, the
continuing correctness of our representations to them, the receipt of a
"comfort letter" from our accountants, the listing of the common stock on the
Nasdaq National Market and no occurrence of an event that would have a material
adverse effect on our business. The underwriters are obligated to purchase and
accept delivery of all the shares, other than those covered by the over-
allotment option described below, if they purchase any of the shares.

  We have granted to the underwriters an option, exercisable for 30 days from
the date of the underwriting agreement, to purchase up to 937,500 additional
shares at the public offering price less the underwriting fees. The
underwriters may exercise the over-allotment option solely to cover over-
allotments, if any, made in connection with this offering. To the extent that
the underwriters exercise the over-allotment option, each underwriter will
become obligated, subject to conditions, to purchase a number of additional
shares approximately proportionate to that underwriter's initial purchase
commitment.

  The underwriters propose to initially offer some of the shares directly to
the public at the public offering price set forth on the cover page of this
prospectus and some of the shares to dealers at the public offering price less
a concession not in excess of $    per share. The underwriters may allow, and
the dealers may re-allow, a concession not in excess of $    per share on sales
to other dealers. After the initial offering of the shares to the public, the
representatives of the underwriters may change the public offering price and
the amount of the concessions.

  The following table shows the underwriting fees to be paid to the
underwriters by us in connection with this offering. The underwriting fee is
equal to the public offering price per share of common stock, less the amount
paid by the underwriters to us per share of common stock. The underwriting fee
will be approximately    percent of the public offering price. The underwriting
fee amounts are shown assuming both no exercise and full exercise of the
underwriters' option to purchase additional shares of the common stock.

  We estimate that the total expenses of this offering, excluding underwriting
fees, will be approximately $1.0 million.

  In order to facilitate the offering of the common stock, the underwriters may
engage in transactions that stabilize, maintain or otherwise affect the market
price of the common stock. Specifically, the underwriters may over-allot shares
of the common stock in connection with this offering, thereby creating a short
position in the common stock for their own account. Additionally, to cover
these over-allotments or to stabilize the market price of the common stock, the
underwriters may bid for, and purchase, shares of the common stock in the open
market. Finally, the representatives, on behalf of the underwriters, also may
reclaim selling concessions allowed to an underwriter or dealer if the
underwriting syndicate repurchases shares distributed by that underwriter or
dealer. Any of these activities may maintain the market price of our common
stock at a level above that which might otherwise prevail in the open market.
The underwriters are not required to engage in these activities and, if
commenced, may end any of these activities at any time.

  At our request, the underwriters have reserved for sale at the initial public
offering price up to       of the shares, or     percent, of our common stock
to be sold in this offering for sale to employees and directors of Data Return
and other persons designated by Data Return. The number of shares available for
sale to the general public will be reduced to the extent that any reserved
shares are purchased. Any reserved shares not purchased will be offered by the
underwriters on the same basis as the other shares offered hereby.

  Internet Prospectus. A prospectus in electronic format is being made
available on a web site maintained by Wit Capital Corporation. In addition,
pursuant to an e-Dealer Agreement, all dealers purchasing shares from Wit
Capital in the offering, the e-Dealers, similarly have agreed to make a
prospectus in electronic format available on the web sites that they maintain.
Other than the prospectus in electronic format, any information on those web
sites that is not part of this prospectus or the registration statement of
which this prospectus forms a part, has not been approved or endorsed by Data
Return or any underwriter and should not be relied on by prospective investors.

  Internet Distribution. The underwriters, at our request, have reserved for
sale at the initial public offering price up to      shares of common stock to
members and visitors to Wit Capital's services or web site who express an
interest in purchasing these shares. The sale of these shares will be made by
Wit Capital. Purchases of the reserved shares will be made through an account
at Wit Capital in accordance with Wit Capital's procedures for opening an
account and transacting in securities. Any of these reserved shares not
purchased by visitors to and users of Wit Capital's services or web site will
be offered by the underwriters to the public on the same terms as the other
shares.

  Wit Capital, a member of the National Association of Securities Dealers,
Inc., will participate in the offering as one of the underwriters. The National
Association of Securities Dealers, Inc. approved the membership of Wit Capital
on September 4, 1997. Since that time, Wit Capital has acted as an underwriter,
e-manager or selected dealer in over 100 public offerings. Except for its
participation as a manager in this offering, Wit Capital has no relationship
with Data Return or any of its founders or significant shareholders.


                                       64

  We have agreed to indemnify the underwriters against liabilities specified in
the underwriting agreement, including civil liabilities under the Securities
Act and liabilities arising from breaches of representations and warranties
contained in the underwriting agreement.

  The representatives of the underwriters have advised us that the underwriters
do not intend to confirm sales to any account over which they exercise
discretionary authority.

  We have applied to list our common stock on the Nasdaq National Market under
the symbol "DRTN."

  Data Return and our directors, officers and substantially all of our current
shareholders have agreed that we, and they, respectively, will not sell,
directly or indirectly, or otherwise dispose of any shares of common stock
without the prior written consent of Bear, Stearns & Co. Inc. for a period of
180 days from the date of this prospectus. However, Bear, Stearns & Co. Inc.
may, in its sole discretion and at any time or from time to time, without
notice to our shareholders or Nasdaq, release all or any portion of the shares
subject to lock-up agreements. We have agreed that for a period of 180 days
after the date of this prospectus we will not, without the prior written
consent of Bear, Stearns & Co. Inc., sell or otherwise dispose of any shares of
common stock.

  Prior to this offering, there has been no public market for our common stock.
Consequently, the initial public offering price for our common stock will be
determined by negotiation among Data Return and the representatives of the
underwriters. The material factors to be considered in determining the public
offering price will be:

  .  prevailing market conditions;

  .  our results of operations in recent periods;

  .  the present stage of our development;

  .  the market capitalizations and stages of development of generally
     comparably companies; and

  . estimates of our business potential.

  CIBC World Markets Corp. acted as the placement agent for the sale of shares
of Data Return's common stock in May and July 1999. In compensation for its
services, CIBC World Markets Corp. received a fee. In addition, individuals
affiliated with CIBC World Markets Corp. purchased shares of common stock on

                         REPORT OF INDEPENDENT AUDITORS

The Board of Directors and Shareholders
Data Return Corporation

  We have audited the accompanying balance sheets of Data Return Corporation as
of March 31, 1998 and 1999, and the related statements of operations, changes
in shareholders' equity and cash flows for the period from September 22, 1997
(inception) to March 31, 1998 and the year ended March 31, 1999. These
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

  In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of Data Return Corporation at
March 31, 1998 and 1999, and the results of its operations and its cash flows
from September 22, 1997 (inception) to March 31, 1998 and the year ended March
31, 1999 in conformity with generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS

                                 March 31, 1999

            (Information as of June 30, 1999 and for the three month
               periods ended June 30, 1998 and 1999 is unaudited)

1.Organization, Basis of Presentation and Significant Accounting Policies

Organization

  Data Return Corporation (the "Company") was incorporated in August 1997 under
the laws of the State of Texas and commenced operations on September 22, 1997
(inception). The Company primarily provides advanced Microsoft Internet hosting
services to businesses, web site developers and other organizations. The
Company's advanced Microsoft hosting services enable its customers to establish
and maintain e-commerce and other applications through which they can conduct
transactions and manage information on a worldwide basis over the Internet.

  The Company's computer equipment, principally servers, is primarily located
in separate facilities owned by two of its vendors. The vendors provide data
center facilities and bandwidth connectivity to the Company on a contractual
basis.

Basis of Presentation

  The accompanying financial statements of the Company reflect the operations
and financial position of the Company for the period from its inception on
September 22, 1997 to March 31, 1998 and for fiscal 1999. The Company was
formed when its founders contributed net assets, principally computer
equipment, with an approximate fair market value of $42,000 and cash of
approximately $17,000 as consideration for 15,440,600 shares of the Company's
common stock.

  The Company does not expect to generate positive cash flow from its
operations for several years. As a result, the Company has obtained and intends
to continue to seek funding from external sources. In addition, the Company
intends to file a registration statement for the initial public offering of the
Company's common stock. The Company contemplates using the proceeds from the
proposed public offering to fund its operations, fund its capital expenditures,
expand its marketing and sales activities, repay its credit facility and for
working capital and other general corporate purposes, including potential
acquisitions and investments and expenses associated with its anticipated move
to a new headquarters facility. Management of the Company believes that the
proceeds from the private issuance of common stock described in Note 9 as well
as the proceeds received, if any, of the proposed public offering will be
sufficient to meet the Company's projected cash needs for at least the next 12
months.

Significant Accounting Policies

 Use of Estimates

  The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions
that affect the amounts reported in the financial statements and accompanying
notes. Actual results could differ from those estimates.

 Revenue Recognition

  Revenues are primarily derived from monthly recurring hosting service fees
and from set-up fees. Basic services, defined as accounts expected to generate
less than $400 monthly, do not require a contract. More

                                      F-7

                   NOTES TO FINANCIAL STATEMENTS--(Continued)

            (Information as of June 30, 1999 and for the three month
               periods ended June 30, 1998 and 1999 is unaudited)

(Continued)

complex services require a contract that is generally six months in length.
These contracts generally are cancelable by either party without penalty upon
30 days' notice. Revenues from these contracts are recognized ratably over the
contractual period as service is delivered. Payments received for billings in
advance of providing services are deferred until the period such services are
provided. Set-up fees are separately priced from hosting services and are
recognized at the time a new customer account is created. Therefore, the
customer has no expectation of any future value from set-up fees after the
account is set up and the service is activated. Set-up costs consist primarily
of labor by technical support personnel to activate the new service and are
incurred at the time of set-up. No future set-up costs are incurred. There is
no obligation of the Company to perform any future set-up services, and the
set-up fees are non-refundable. Following expiration of the initial contract
period and upon renewal of the contract by the customer, there are no
additional set-up charges and the renewal prices for hosting services are
generally unchanged from the original contract period.

  The Company's accounts receivable are financial instruments that expose the
Company to credit risk, as defined by Statement of Financial Accounting
Standards No. 105, Disclosure of Information About Financial Instruments with
Off-Balance Sheet Risk and Financial Instruments with Concentrations of Credit
Risk. Accounts receivable are due from commercial entities to whom credit is
extended based on evaluation of the customer's financial condition, and
generally collateral is not required. Anticipated credit losses are provided
for in the financial statements and have been within management's expectations
for all periods presented.

 Property and Equipment

  Property and equipment is stated at cost. Depreciation is computed using the
straight-line method over estimated useful lives of the property and equipment,
generally three years for computer equipment and up to seven years for
furniture and fixtures. Equipment acquired under capital leases is amortized
using the straight-line method over the lesser of the lease term or the
estimated useful life of the asset, generally three years. The cost of license
agreements with software vendors are amortized over the term of the agreements.

 Restricted Cash

  Restricted cash consists of a certificate of deposit which is pledged as
collateral for the Company's notes payable.

 Impairment of Long-Lived Assets

  In accordance with Statement on Accounting Standards No. 121, Accounting for
the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed
Of, the Company reviews its long-lived assets for impairment when events or
changes in circumstances indicate the carrying value of such assets may not be
recoverable. This review consists of a comparison of the carrying value of the
asset with the asset's expected future undiscounted cash flows without interest
costs. Estimates of expected future cash flows represent management's best
estimate based on reasonable and supportable assumptions and projections. If
the expected future cash flow exceeds the carrying value of the asset, no
impairment indicator is considered present. If the carrying value exceeds the
future cash flow, an impairment indicator is considered present. Such
impairment would be measured and recognized using a discounted cash flow
method.

 Financial Instruments

  The carrying amounts reported in the balance sheets for accounts receivable
and accounts payable approximate their fair values.

            (Information as of June 30, 1999 and for the three month
               periods ended June 30, 1998 and 1999 is unaudited)


1.Organization, Basis of Presentation and Significant Accounting Policies--
(Continued)

 Purchase Commitments

  The Company has an obligation to acquire certain minimum amounts of co-
location space, technical assistance, broadband service and private line
service. In the event the Company expects to incur a loss in fulfilling its
future obligations, the estimated loss will be accrued at the date the Company
first believes a loss is likely to be incurred.

 Advertising Costs

  The Company expenses advertising costs as incurred. Advertising expense
amounted to $25,200 and $296,400 for the period from September 22, 1997
(inception) to March 31, 1998, and the year ended March 31, 1999, respectively.

 Stock Based Compensation

  The Company accounts for employee stock based compensation in accordance with
Accounting Principles Board Opinion No. 25, Accounting for Stock Issued to
Employees, and related Interpretations, because the alternative fair value
accounting model provided under Statement of Financial Accounting Standards No.
123, Accounting for Stock Based Compensation (SFAS 123) is not required.
Accordingly, in cases where exercise prices equal or exceed fair market value
of the underlying common stock, the Company recognizes no compensation expense.
In cases where exercise prices are less than the fair value, compensation is
recognized over the lesser of the period of performance or vesting period.

 Income Taxes

  Deferred tax assets and liabilities are determined based on differences
between financial reporting and tax bases of assets and liabilities and are
measured using the enacted tax rates and laws that will be in effect when the
differences are expected to reverse.

 Comprehensive Income

  In June 1997, the FASB issued Statement of Financial Accounting Standards No.
130, Reporting Comprehensive Income (SFAS 130). SFAS 130 requires that total
comprehensive income (loss) be disclosed with equal prominence as net income
(loss). The Company's comprehensive loss is equal to its net losses for all
periods presented.

 Segment Reporting

  The Company operated during all periods in a single segment when applying the
management approach defined in Statement of Financial Accounting Standards No.
131, Disclosures about Segments of an Enterprise and Related Information.

 Recent Accounting Pronouncements

  On March 4, 1998, the Accounting Standards Executive Committee of the
American Institute of Certified Public Accountants (AICPA) issued Statement of
Position No. 98-1, "Accounting for the Costs of Computer

                                      F-9

Software Developed or Obtained for Internal Use" (SOP 98-1). SOP 98-1 requires
computer software costs related to internal software that are incurred in the
preliminary project stage to be expensed as incurred. Once the capitalization
criteria of SOP 98-1 have been met, external direct costs of materials and
services consumed in developing or obtaining internal-use computer software;
payroll and payroll-related costs for employees who are directly associated
with and who devote time to the internal-use computer software project (to the
extent of the time spent directly on the project); and interest costs incurred
when developing computer software for internal use should be capitalized. SOP
98-1 is effective for financial statements for fiscal years beginning after
December 15, 1998. Accordingly, the Company has adopted SOP 98-1 in its
financial statements for the year ending March 31, 2000.

  In April of 1998, the Accounting Standards Executive Committee of the AICPA
issued Statement of Position No. 98-5, Reporting on the Costs of Start-up
Activities, which requires that costs related to such activities be expensed as
incurred. SOP 98-5 is effective for financial statements for fiscal years
beginning after December 15, 1998. Accordingly, the Company has adopted SOP 98-
5 in the financial statements for the year ending March 31, 2000. The adoption
of SOP 98-5 had no material impact on our financial statements.

 Net Loss Per Share

  Net loss per share is computed using the weighted average number of shares of
common stock outstanding during each period for basic and diluted earnings per
share. No common stock equivalents are considered in the calculation of diluted
earnings per share as the Company has incurred a loss for all periods presented
and the effect of common stock equivalents would be anti-dilutive.

 Unaudited Interim Financial Statements

  The unaudited interim consolidated financial statements as of June 30, 1999,
and for the three month periods ended June 30, 1998 and 1999, have been
prepared in accordance with generally accepted accounting principles for
interim financial information and with Rule 10-01 of Regulation S-X.
Accordingly, they do not include all of the information and footnotes required
by generally accepted accounting principles for complete financial statements.
They do reflect all adjustments (consisting only of normal recurring entries)
which, in the opinion of the Company's management, are necessary for a fair
presentation of the results for the interim periods presented.

  The results of operations for the three month period ended June 30, 1999, are
not necessarily indicative of the results that may be expected for any other
interim period or for the full year.

5.Shareholders' Equity

 Common Stock

  Pursuant to a Stock Sales Agreement (the Agreement) dated February 20, 1998,
between the Company and a private investor, the Company sold 2,152,000 shares
of its common stock for $0.46 per share. The Agreement provided for the
issuance of the shares in return for $500,000 cash and a promissory note in the
amount of $500,000 that has been repaid. The Agreement provided the investor
the right to acquire an additional 2,690,000 shares of the Company's common
stock during a specified period in 2001 for $0.37 per share and provided the
Company the right to require the investor to purchase the shares for a period
beginning in February 1999 through August 2001. In February of 1999, the
Company exercised its rights under the Agreement and sold 2,690,000 shares of
its common stock to the investor for $0.37 per share.

  The Agreement also provides the investor additional rights including: a right
of first refusal to participate in any future equity offerings up to the total
amount of such offerings and on the same terms as those offered to other
investors, a right to designate two members of the Company's five member Board
of Directors and a requirement for unanimous approval by the Board of Directors
for certain transactions.

  The investor's rights terminate upon the earlier to occur of: the mutual
agreement of the Company and the investor, events the result of which are such
that the investor owns less than 5 percent of the issued and outstanding common
stock of the Company, consummation of a public offering of the Company's
capital stock or a breach by the investor of his obligations.

 Stock Based Compensation Arrangements

  The Company's 1998 Stock Option Plan (the Plan) provides for the issuance to
employees of options to acquire 3,308,700 shares of common stock. The options
are to be issued at fair market value, as defined, and vest as approved by the
Board of Directors. Options generally expire 10 years from the date of grant
and automatically expire at termination of employment. The vesting period for
options to acquire 901,150 shares of common stock accelerates to the effective
date of any registration statement filed by the Company or in the event of a
merger or acquisition of the Company.

  Subsequent to March 31, 1999, the Company adopted the 1999 Long-Term
Incentive Plan. See Note 9.

  The following table summarizes the stock option activity related to the
Company:

5.Shareholders' Equity--(Continued)

  Outstanding options as of March 31, 1999, had a weighted average remaining
contractual life of approximately nine years and a weighted average fair value
at issuance of $0.36 based on the minimum value method.

  Certain employees of the Company have been granted options under the Plan to
purchase shares of the Company's common stock at less than fair market value.
Prior to the adoption of the Plan, an employee was granted 3,308,700 options at
a price below fair market value which vest over 4 years. The vesting period for
the 3,308,700 options accelerates to the effective date of any registration
statement filed by the Company. The Company recorded deferred stock
compensation of $1,277,000, $328,000 and $874,100 for the period from
September 22, 1997 (inception) through March 31, 1998, the year ended March 31,
1999 and the three month period ended June 30, 1999, respectively, for the
difference between the exercise price and the deemed fair value of the
Company's common stock underlying certain options granted. These amounts are
being amortized over the vesting period of the individual options, generally
four years. The stock compensation expense charged to income amounted to
$61,300 and $348,800 for the period from September 22, 1997 (inception) to
March 31, 1998 and the year ended March 31, 1999, respectively. The stock
compensation expense charged to income amounted to $84,600 and $139,500 for the
three month periods ended June 30, 1998 and 1999, respectively.

  As discussed in Note 1, the Company accounts for its stock based awards to
employees using the intrinsic value method in accordance with APB Opinion No.
25, "Accounting for Stock Issued to Employees," and its related
interpretations.

  SFAS No. 123 requires the disclosure of pro forma net income (loss) and net
income (loss) per share as if the Company had adopted the fair value method
since September 22, 1997 (inception). Under SFAS No. 123, the fair value of
stock based awards to employees is calculated through the use of option pricing
models, even though such models were developed to estimate the fair value of
freely tradable, fully transferable options without vesting restrictions, which
significantly differ from the Company's stock option awards. These models also
require subjective assumptions, including future price volatility and expected
time to exercise, which greatly affect the calculated values.

  The Company's calculations for employee grants were made using the minimum
value method using the following weighted average assumption: expected life,
four years; risk free interest rate of 6 percent; no dividends during the
expected term; and a volatility of zero as the Company is private and has no
trading history. If the computed values of the Company's stock based awards
were amortized to expense over the vesting period of the awards as specified
under SFAS No. 123, net loss would have been $191,320 ($0.01 per basic and
diluted share) and $1,289,160 ($0.07 per basic and diluted share) for the
period from September 22, 1997 (inception) to March 31, 1998 and the year ended
March 31, 1999, respectively.

6.Income Tax Information

  At March 31, 1998 and 1999, the Company had temporary differences between the
carrying amounts of assets and liabilities for financial reporting purposes and
such amounts as measured by tax laws. Significant components of the Company's
deferred tax assets and liabilities were as follows:

</TABLE>

  At March 31, 1999, the Company's net operating loss carryforward for federal
income tax purposes is approximately $980,000, expiring in 2013 and 2014. The
Company has recorded a valuation reserve for its net deferred tax benefit for
the period ended March 31, 1998 and the year ended March 31, 1999 due to
uncertainty that the Company will generate sufficient taxable income during the
carryforward period to realize the benefit of its deferred tax asset. In
addition, in connection with the equity transactions that have taken place
since its inception and the proposed initial public offering, the Company may
experience a change in control pursuant to Internal Revenue Code Section 382.
As such, the net operating loss carryforward may be limited as to its possible
use in future periods.

7.Commitments

sales activities, repay its credit facility and for working capital and other
general corporate purposes, including potential acquisitions and investments
and expenses associated with its anticipated move to a new headquarters
facility.

 Adoption of the 1999 Long-Term Incentive Plan

  In July 1999, the Company adopted the 1999 Long-Term Incentive Plan. The Plan

9.Subsequent Events--(Continued)

  In addition, on July 26, 1999, Level 3 Communications, Inc. (Level 3)
acquired 1,952,940 shares of the Company's common stock in exchange for a $5.0
million credit to be applied to the purchase of future bandwidth services. Use
of the credit is as allowed by the Service Credit Agreement. The credit can be
applied as payment for services in excess of the minimum purchases required
under the Strategic Marketing and Sales Agreement (see below) beginning on
January 1, 2001. The Company has a limited right to reacquire the stock in the
event that Level 3 fails to fulfill its obligations under the Service Credit
Agreement or fails to deliver the bandwidth pursuant to the terms of the
Service Credit Agreement. The number of shares subject to the Company's right
to reacquire the stock will be reduced pro rata in each quarter of calendar
year 2001 by the greater of the credit applied to future purchases of bandwidth
or 25% of the total shares. The stock can be reacquired by the Company at the
original purchase price by the Company's forgiveness of the remaining balance
of the credit. In the event the Company's right to reacquire the stock is
exercised, Level 3 is required to pay the Company $750,000, reduced ratably,
based on the amount of bandwidth credit used by the Company.

 Strategic Marketing and Sales Agreement

 The Company entered into a Strategic Marketing and Sales Agreement with Level
3 on July 1, 1999. The Strategic Marketing and Sales Agreement provides that
the Company will acquire most of its requirements for co-location space,
technical assistance, broadband service and private line service (collectively
the "Services") over a five year period commencing with the date of the
agreement, which are substantially similar or perform substantially the same
function as the Services from Level 3. The Agreement also provides for joint
sales and marketing efforts between the Company and Level 3, including cross
training of personnel, and provides that Level 3 will designate the Company as
a preferred provider for Advanced Microsoft Hosting Service. The Company will
pay commission to Level 3 personnel for new customers generated by their leads.

  The Company's annual commitment for the Services is as follows for its year
ended March 31:

</TABLE>

Payments for the minimum annual purchase commitments will be required
regardless of whether the Company uses the Services. The Company can apply the
$5.0 million credit described above beginning on January 1, 2001 to purchases
in excess of the minimum annual commitments required by the Strategic Marketing
and Sales Agreement. Pricing of the Services will be based on Level 3's
established market prices at the time the service is provided.

 ASP and Server Agreement

  The Company entered into an agreement with Compaq to purchase the lesser of
2,000 servers or the number of servers reasonably necessary to operate the
Company's business. The requirement to purchase the servers is contingent upon
Compaq providing financing for the servers on competitive terms, upon the
price, performance and quality of the servers being reasonably satisfactory to
the Company and upon Compaq's commitment to deliver these servers on the
schedule we request.

 Microsoft Agreements (unaudited)

  On September 3, 1999, the Company agreed to sell $5.0 million of its common
stock for a per share purchase price equal to the lesser of the midpoint of the
lowest filing range and the price to public. Microsoft will also acquire a
warrant to purchase $3.75 million of the Company's common stock at the same per
share purchase price. Microsoft is entitled to one demand and unlimited
"piggyback" registration rights. Microsoft also has a right of first refusal
that does not include this offering and that terminates upon completion of the
initial public offering. This transaction will close the earlier of the day
after the pricing of this offering and December 12, 1999.


  In addition, on September 3, 1999, the Company entered into a five-year
Development, License and Co-Marketing Agreement with Microsoft to grant a non-
exclusive perpetual license to proprietary installation tools for third-party

ITEM 14. Indemnification of Directors and Officers

  We have authority under Article 2.02A.(16) and 2.02-1 of the Texas Business
Corporation Act (the "TBCA") to indemnify our directors and officers to the
extent provided for in the TBCA. Our Restated Articles of Incorporation permit
indemnification of directors and officers to the fullest extent permitted by
law.

  The TBCA provides in part that a corporation may indemnify a director or
officer or other person who was, is, or is threatened to be made a named
defendant or respondent in a proceeding because the person is or was a
director, officer, employee or agent of the corporation, if it is determined
that such person (i) conducted himself in good faith; (ii) reasonably believed,
in the case of conduct in his official capacity as a director or officer of the
corporation, that his conduct was in the corporation's best interests, and, in
all other cases, that his conduct was at least not opposed to the corporation's
best interests; and (iii) in the case of any criminal proceeding, had no
reasonable cause to believe that this conduct was unlawful.

  A corporation may indemnify a person under the TBCA against judgments,
penalties, (including excise and similar taxes), fines, settlement, and
reasonable expenses actually incurred by the person in connection with the
proceeding. If the person is found liable to the corporation or is found liable
on the basis that personal benefit was improperly received by the person, the
indemnification is limited to reasonable expenses actually incurred by the
person in connection with the proceeding, and shall not be made in respect of
any proceeding in which the person shall have been found liable for willful or
intentional misconduct in the performance of his duty to the corporation.

  A corporation may also pay or reimburse expenses incurred by a person in
connection with his appearance as a witness or other participation in a
proceeding at a time when he is not a named defendant or respondent in the
proceeding.

  Article Eight of our Restated Articles of Incorporation provides that, to the
fullest extent permitted by the TBCA as it exists or as it may be amended, no
director shall be personally liable to Data Return or our shareholders for
monetary damages for breach of fiduciary duty as a director.

  Prior to consummation of this offering, we intend to obtain directors and
officers liability insurance.

ITEM 17. Undertakings

  The undersigned Registrant hereby undertakes to provide to the underwriters,
at the closing specified in the underwriting agreement, certificates in such
denominations and registered in such names as required by the underwriters to
permit prompt delivery to each purchaser.

  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 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 Act and will be governed by the final
adjudication of such issue.

  The undersigned Registrant hereby undertakes that:

    (1) For 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 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 securities at the time
  shall be deemed to be the initial bona fide offering thereof.

                                       of

                                                    of the Above-Referenced Date

     Upon delivery of this Warrant, together with payment of the Exercise Price
multiplied by the total number of shares of Common Stock thereby purchased (the

other office or agency as the Company may designate by notice in writing to the
holder hereof, the holder of this Warrant shall be entitled to receive a
certificate or certificates for the shares of Common Stock so purchased.  The
date at which the Company receives (i) this Warrant and (ii) payment for the
shares of Common Stock, either by payment in cash, or by check, or wire
transfer, shall be referred to herein as the "Exercise Date".  All shares of
Common Stock which may be issued upon the exercise of this Warrant ("Warrant
Shares") shall, upon issuance, be fully paid, validly issued and non-assessable,

          1.1    Time of Exercise.

                 (a)  This Warrant may be exercised in whole or in part

Warrant at the principal office of the Company together with notice of such
election, in which event the Company shall issue to the holder hereof a number
of shares of Common Stock computed using the following formula:


     S = P x  (F-E)
             -------
                F

            S =   The number of shares of Common Stock to be issued to the
                  Warrantholder.

            P =   The number of shares of Common Stock purchasable under this
                  Warrant.

            F =   The Fair Market Value (as defined below) of 1 share of Common
                  Stock.

            E =   The Exercise Price (as adjusted to the date of such
                  calculations).

          For purposes of this Section 1.3, the "Fair Market Value" of the
Common Stock shall be determined in good faith by the Board of Directors of the
Company; provided, that if the Common Stock is then trading on a national
securities exchange or in the over-the-counter market, such

                                      -2-
<PAGE>

determination shall be made with reference to the average closing price of the
Common Stock in such trading over the 20 trading days immediately preceding the
exercise of the Warrant.

          1.4    Certificates for Shares.  The Company shall, within 30 days
after the Exercise Date, prepare a certificate for the shares of Common Stock
purchased in the name of the holder of this Warrant, or as such holder may
direct (subject to the restrictions upon transfer contained herein and upon
payment by such holder hereof of any applicable transfer taxes). In case the
Warrantholder shall exercise this Warrant with respect to less than all of the
shares of Common Stock that may be purchased under this Warrant, the Company
shall execute a new warrant in the form of this Warrant for the balance of such
shares and deliver such new warrant to the Warrantholder.

          1.5    Warrant Register.  The Company shall maintain at its principal
executive offices books for the registration and the registration of transfer of
Warrants.  The Company may deem and treat the Warrantholder as the absolute
owner hereof (notwithstanding any notation of ownership or other writing thereon
made by anyone) for all purposes and shall not be affected by any notice to the
contrary.

     2.   Certain Adjustments.

     2.1  Exercise Price; Adjustment of Number of Shares.  The Exercise Price
set forth in Section 1 hereof and the number of shares purchasable hereunder
shall be subject to adjustment from time to time as hereinafter provided.

     2.2  Reorganization, Reclassification, Consolidation, Merger or Sale.  If
any capital reorganization or reclassification of the capital stock of the
Company, or any consolidation or merger of the Company with another entity, or
the sale of all or substantially all of the Company's assets to another person
or entity (collectively referred to as a "Transaction") shall be effected in
such a way that holders of Common Stock shall be entitled to receive stock,
securities, cash or assets with respect to or in exchange for Common Stock,
then, as a condition of such Transaction, reasonable, lawful and adequate
provisions shall be made whereby the holder of this Warrant shall thereafter
have the right to purchase and receive upon the basis and upon the terms and
conditions specified in this Warrant, upon exercise of this Warrant and in lieu
of the Warrant Shares immediately theretofore purchasable and receivable upon
the exercise of the rights represented hereby, such number, amount and like kind
of shares of stock, securities, cash or assets as may be issued or payable
pursuant to the terms of the Transaction with respect to or in exchange for the
number of shares of Common Stock immediately theretofore purchasable and
receivable upon the exercise of the rights represented hereby as if such shares
were outstanding immediately prior to the Transaction, and in any such case
appropriate provision shall be made with respect to the rights and interest of
the holders to the end that the provisions hereof (including, without
limitation, provisions for adjustments of the Exercise Price and of the number
of Warrant Shares purchasable and receivable upon the exercise of this Warrant)
shall thereafter be applicable, as nearly as may be practicable, in relation to
any shares of stock or securities thereafter deliverable upon the exercise
hereof.

     2.3  Stock Splits, Stock Dividends and Reverse Stock Splits.  In case at
any time the Company shall subdivide its outstanding shares of Common Stock into
a greater number of shares,

                                      -3-
<PAGE>

or shall declare and pay any stock dividend with respect to its outstanding
stock that has the effect of increasing the number of outstanding shares of
Common Stock, the Exercise Price in effect immediately prior to such subdivision
or stock dividend shall be proportionately reduced and the number of Warrant
Shares purchasable pursuant to this Warrant immediately prior to such
subdivision or stock dividend shall be proportionately increased, and
conversely, in case at any time the Company shall combine its outstanding shares
of Common Stock into a smaller number of shares, the Exercise Price in effect
immediately prior to such combination shall be proportionately increased and the
number of Warrant Shares purchasable upon the exercise of this Warrant
immediately prior to such combination shall be proportionately reduced.

     2.4  Issuance of Additional Shares of Common Stock.  If at any time prior
to the Expiration Date the Company shall issue any Additional Shares of Common
Stock for a consideration per share (the "Subsequent Issue Price") less than the
Exercise Price as in effect immediately prior to such issuance, the Exercise
Price shall be reduced to the lower of the prices calculated by dividing (i) an
amount equal to the sum of (x) the number of shares of Common Stock outstanding
immediately prior to such issuance multiplied by the Exercise Price then in
effect plus (y) the aggregate consideration, if any, received by the Company in
connection with such issuance by (ii) the total number of shares of Common Stock
outstanding immediately after such issuance.

     For purposes of this Section 2.4, "Additional Shares of Common Stock" shall
mean all shares of Common Stock issued or issuable by the Company after the
Original Issue Date, other than (i) shares of Common Stock issuable under the
Company's employee stock option plan as approved by the Company's Board of
Directors (the "Employee Stock") and (ii) shares issued by the Company in an
underwritten public offering.  For purposes of this Section 2.4, in the case of
convertible securities, there shall be determined the price per share for which
Additional Shares of Common Stock are issuable upon the conversion or exchange
thereof, such determination to be made by dividing (i) the total amount received
or receivable by the Company as consideration for the issue or sale of such
convertible Securities, plus the minimum aggregate amount of additional
consideration, if any, payable to the Company upon conversion or exchange
thereof by (ii) the maximum aggregate number of additional Shares of Common
Stock issuable upon conversion or exchange of all such convertible securities
for such minimum aggregate amount of additional consideration; and such issue or
sale shall be deemed to be an issue or sale for cash (as of the date of issue or
sale of such convertible securities, whether or not then exercisable or
convertible) of such maximum number of Additional Shares of common stock at the
price per share so determined.

     If any rights of conversion or exchange evidenced by convertible securities
the issuance of which resulted in an adjustment to the Exercise Price and the
number of Warrant Shares issuable hereunder pursuant to this Section 2.4 shall
expire without having been exercised, or if any such convertible securities are
exercised for a consideration greater than or for a number of Additional Shares
of Common Stock less than those used for purposed of determining the adjustment
to the Exercise Price provided in this Section 2.4, the adjusted Exercise Price
shall forthwith be readjusted to such Exercise Price as would have been in
effect had an adjustment with respect to such Convertible Securities been made
on the basis that the only Additional Shares of Common Stock issued or sold were
those issued upon the conversion or exchange of such convertible securities, and

                                      -4-
<PAGE>

that they were issued or sold for the consideration actually received by the
Company upon such exercise, plus the consideration, if any, actually received by
the Company for the granting of such Convertible Securities.

     Notwithstanding anything to the contrary in this Section 2.4, in no event
shall (i) the Exercise Price be increased or (ii) the number of Warrant Shares
purchasable hereunder be decreased pursuant to the provisions of this Section
2.4.

     2.5  Company to Prevent Dilution.  In case at any time or from time to time
conditions arise by reason of action taken by the Company which are not
adequately covered by this Section 2, and which might materially and adversely
affect the exercise rights of the holder hereof, unless the adjustment necessary
shall be agreed by the Company and the holder hereof, the Board of Directors of
the Company shall appoint a firm of independent certified public accountants of
national standing, reasonably acceptable to the holder, who at the Company's
expense shall give their opinion upon the adjustment necessary with respect to
the Exercise Price and the number of Warrant Shares purchasable upon exercise of
this Warrant, if any, so as to preserve, without dilution, the exercise rights
of the holder hereof.  In the event that the holder disputes such adjustment,
the holder shall be entitled to select an additional firm of independent
certified public accountants of national standing and paid for by the holder to
calculate such adjustment and the Company and the holder shall use their good
faith best efforts to agree on such adjustment based on the reports of the two
accounting firms.  In the event that the Company and the holder are still unable
to reach agreement as to such adjustment, the Company and the holder agree to
submit such determination to binding arbitration.  Upon determination of such
adjustment, the Board of Directors shall forthwith make the adjustments
described therein.

     2.6  Dissolution, Liquidation or Wind-Up.  In case the Company shall, at
any time prior to the exercise of this Warrant, dissolve, liquidate or wind up
its affairs, the holder hereof shall be entitled, upon the exercise of this
Warrant, to receive, in lieu of the Warrant Shares which the holder would have
been entitled to receive, the same kind and amount of assets as would have been
issued, distributed or paid to such holder upon any such dissolution,
liquidation or winding up with respect to such Warrant Shares, had such holder
hereof been the holder of record of the Warrant Shares receivable upon the
exercise of this Warrant on the record date for the determination of those
persons entitled to receive any such liquidating distribution.

     2.7  Accountant's Certificate.  In each case of an adjustment in the
Exercise Price, number of Warrant Shares or other stock, securities or property
receivable upon the exercise of this Warrant, the Company shall compute, and
upon the holder's request shall at the Company's expense cause independent
public accountants of recognized standing selected by the Company and reasonably
acceptable to the holder to certify such computation, such adjustment in
accordance with the terms of this Warrant and prepare a certificate setting
forth such adjustment and showing in detail the facts upon which such adjustment
is based, including a statement of (i) the number of shares of Common Stock of
each class outstanding or deemed to be outstanding, (ii) the adjusted Exercise
Price and (iii) the number of Warrant Shares issuable upon exercise of this
Warrant.  The Company will forthwith mail a copy of each such certificate to the
holder hereof.  In the event that the holder disputes such adjustment, the
holder shall be entitled to select an additional firm of independent certified
public

                                      -5-
<PAGE>

accountants of national standing and paid for by the holder to certify such
adjustment and the Company and the holder shall use their good faith best
efforts to agree on such adjustment based on the reports of the two accounting
firms. In the event that the Company and the holder are still unable to reach
agreement as to such adjustment, the Company and the holder agree to submit such
determination to binding arbitration. Upon determination of such adjustment, the
Board of Directors shall forthwith make the adjustments described therein.

     3.   Representations and Warranties of Warrantholder.  Warrantholder hereby
represents and warrants that:

          3.1    Purchase Entirely for Own Account.  This Warrant and the Common
Stock issuable upon exercise hereof (collectively, the "Securities") will be
acquired for investment for Warrantholder's own account, not as a nominee or
agent, and not with a view to the resale or distribution of any part thereof,
and Warrantholder has no present intention of selling, granting any
participation in, or otherwise distributing the same.  Warrantholder does not
have any contract, undertaking, agreement or arrangement with any person to
sell, transfer or grant participation to any person with respect to any of the
Securities.  Warrantholder represents that it has full power and authority to
enter into this Warrant.

          3.2    Investment Experience.  Warrantholder acknowledges that it is
able to protect its own economic interests, can bear the economic risk of its
investment and has such knowledge and experience in financial or business
matters that it is capable of evaluating the merits and risks of the investment
in the investment in this Warrant.  Warrantholder also represents it has not
been organized for the purpose of acquiring this Warrant.

          3.3    Accredited Investor.  Warrantholder is an "accredited investor"
within the meaning of Rule 501 of Regulation D promulgated under the Securities
Act of 1933 (the "Act").

          3.4    Restricted Securities.  Warrantholder understands that the
Securities are characterized as "restricted securities" under the Act inasmuch
as they are being acquired from the Company in a transaction not involving a
public offering, and that under the Act such securities may be resold without
registration under the Act only in certain limited circumstances.  In this
connection, Warrantholder represents that it is familiar with Rule 144
promulgated under the Act and understands the resale limitations imposed thereby
and by the Act.  Warrantholder further acknowledges that it will not be able to
avail itself of Rule 144 unless and until the Company effects a public offering
of its Common Stock.

          3.5    Further Limitations on Disposition.  Without in any way
limiting the representations set forth above, Warrantholder further agrees not
to make any disposition of all or any portion of the Securities unless and
until:

                 (a)  there is then in effect a Registration Statement under the
Act covering such proposed disposition and such disposition is made in
accordance with such Registration Statement; or

                                      -6-
<PAGE>

                 (b)  (i)  such Warrantholder shall have notified the Company of
the proposed disposition and shall have furnished the Company with a detailed
statement of the circumstances surrounding the proposed disposition, and (ii) if
reasonably requested by the Company, such Warrantholder shall have furnished the
Company with an opinion of counsel, reasonably satisfactory to the Company, that
such disposition will not require registration of such shares under the Act.

     4.   Miscellaneous.

          4.1    Successors and Assigns.  The terms of this Warrant shall be
binding upon and shall inure to the benefit of any successors or assigns of the
Company and of the holder hereof and of the Common Stock issued upon the
exercise hereof.

          4.2    No Rights as Shareholder.  No Warrantholder, as such, shall be
entitled to vote or receive dividends or be deemed to be a shareholder of the
Company for any purpose, nor shall anything contained in this Warrant be
construed to confer upon the holder of this Warrant, as such, any rights of a
shareholder of the Company or any right to vote, give or withhold consent to any
corporate action, receive notice of meetings, receive dividends or subscription
rights, or otherwise.

          4.3    No Fractional Shares.  No fractional share shall be issued upon
exercise of this Warrant.  The Company shall, in lieu of issuing any fractional
share, pay Warrantholder a sum in cash equal to the fair market value of such
fraction on the date of exercise.

          4.4    Lock-Up.  Warrantholder hereby agrees that it shall not,
without the consent of the managing underwriter, sell, transfer, pledge,
hypothecate or otherwise transfer or dispose of any Common Stock or other shares
of stock of the Company then owned by Warrantholder for up to 180 days following
the effective date of a registration statement (other than a registration
statements relating to any employee benefit plan, or with respect to a corporate
reorganization or other transaction under Rule 145 promulgated under the
Securities Act )of the Company for an initial public offering filed under the
Securities Act; provided, however, that all officers and directors of the
Company and all holders of Common Stock (or options or other rights to acquire
Common Stock) equal to at least 1% of the Company's voting securities (on a
fully-diluted basis) enter into similar agreements. In order to enforce the
foregoing covenant, the Company shall have the right to place restrictive
legends on the certificates representing the shares subject to this Section and
to impose stop transfer instructions with respect to the Common Stock and such
other shares of stock of Warrantholder.

          4.5    Replacement.  Upon receipt of evidence reasonably satisfactory
to the Company of the loss, theft, destruction or mutilation of this Warrant
and, in the case of any such loss, theft or destruction, upon delivery of an
indemnity agreement reasonably satisfactory in form and amount to the Company,
or in the case of any such mutilation, upon surrender and cancellation of such
Warrant, the Company will execute and deliver, in lieu thereof, a new Warrant of
like data and tenor.

          4.6    Business Days.  If the last or appointed day for the taking of
any action or the expiration of any right required or granted herein shall be a
Saturday or Sunday or shall be a legal

                                      -7-
<PAGE>

holiday, then such action may be taken or such right may be exercised on the
next succeeding day not a legal holiday.

          4.7    Governing Law.  This Warrant shall be governed by the internal
laws of the State of Texas, as applied to contracts between residents of Texas
and to be performed entirely within Texas, without regard to the application of
conflict of law rules.

          4.8    Agreement by Warrantholder.  Receipt of this Warrant by the
holder hereof shall constitute acceptance of and agreement to the foregoing
terms and conditions.

     5.   Amendment.  Any term of this Warrant may be amended and the observance
of any term of this Warrant may be waived (either generally or in a particular
instance and either retroactively or prospectively) with the written consent of
the Company and the holder hereof.

     IN WITNESS WHEREOF, Data Return Corporation has caused this Warrant to be
signed by its duly authorized officer.

        Section 4.1.1 ("Microsoft Improvements");

        4.2.2    Reproduce, license, rent, lease or otherwise distribute, and
        have reproduced, licensed, rented, leased or otherwise distributed, to
        and by third parties, source and/or object code versions of the
        Microsoft Improvements, and any Derivative Technology thereof;

        4.2.3    Grant the rights set forth in Section 4.2.1 in the Microsoft

        4.2.4    Grant to third parties the right to reproduce and distribute to

        4.2.3.

4.3     Ownership.  Except as expressly licensed to Microsoft in this Agreement,
Data Return retains all right, title and interest in and to the Initial Scripts;
provided, however, that, subject to the license grant in Section 4.1 and Data
Return's ownership of the underlying Initial Scripts, Microsoft shall own all
right, title and interest in and to any Derivative Technology of the Initial
Scripts created by or for Microsoft.

5.      Co-Marketing.

5.1     White Paper(s).  The White Paper(s) shall be co-branded in a manner
mutually agreeable to the parties. Each party may distribute such co-branded
White Paper(s) to such recipients and in such manner as it desires without the
consent of the other party.  Each party may include, without co-branding,
portions of the White Paper(s) into other materials, including without
limitation marketing collateral, without the consent of the other party.  Data
Return may also distribute the White Paper(s) as a whole without co-branding
without Microsoft's consent; however, Microsoft must obtain Data Return's prior
written consent to distribute any White Paper, without co-branding, which
consent may not be unreasonably withheld or delayed.

5.2     Training Seminars.  Data Return and Microsoft shall provide four (4) one
day (8 hour) training seminars with regard to the Initial Scripts and related
White Paper, two of which shall occur at least thirty (30) days after acceptance
by Microsoft of both the Initial Scripts and White Paper therefor pursuant to
Section 2.2 above (the first two seminars currently anticipated to occur in mid-
October of 1999) and two of which shall occur four months later (the second two
seminars currently anticipated to occur in February of 2000).  The training
seminars shall occur at the Microsoft Partner Center in Redmond, Washington.
Data Return shall act as the primary leader of the

                                                                    Page 3 of 12
<PAGE>

first two training seminars, with Microsoft assisting; Microsoft shall act as
the primary leader of the second two training seminars, with Data Return
assisting. The training seminars shall be provided to Microsoft's value-added
provider channel, including without limitation, value-added resellers, solutions
partners and system integrators. Microsoft shall determine the list of invitees.

6.      Programs and Designations.  The Contact Representative for Microsoft set
forth in Section 9 shall use reasonable efforts assist Data Return in obtaining
access to the relevant Microsoft product units to facilitate inclusion in all
early adopter programs, beta programs, councils, and designations that  for
hosting providers using Microsoft Windows NT or Microsoft Windows 2000, and all
early adopter programs, beta programs,  councils, and designations that are
specific to Exchange Server, Commerce Server and Microsoft Office. Data Return
understands that each such program, council or designation has its own
participation requirements and nothing in this provision guarantees that Data
Return will be included in such programs, councils or designations.

7.      Options With Respect To New Installation Scripts.  During the Term of
this Agreement, Data Return will provide written notice to Microsoft if and when
Data Return plans to develop additional automated installation scripts which are
built on Microsoft Windows 2000 and which package, utilize or include Commerce
Server, Exchange Server and/or Microsoft Office. Such notice shall be provided
at the time that the project scope for such installation scripts is complete.
The parties shall discuss in good faith, and use their best efforts to decide
within thirty (30) days after the notice is given to Microsoft, whether to
include such script(s) within this Agreement and have Microsoft provide the same
assistance and obtain the same rights with respect to such scripts as Microsoft
has with respect to the Initial Scripts. If the parties agree to include such
script(s) within this Agreement, the rights and obligations between the parties
with respect to the such scripts (the "New Script(s)") shall be identical to the
rights and obligations with regard to the Initial Scripts set forth in Sections
2, 3, 4 and 5 above, with the difference that the Microsoft Consulting Service
support shall be limited to thirty (30) hours per New Script and that the
parties shall mutually agree on the delivery schedules for the New Scripts and
related White Paper(s). Should tthe parties decide not to include such script(s)
within this Agreement, Data Return may develop the automated install scripts
referenced in such notice without any further obligations to Microsoft.

8.      Revenue Sharing. In consideration of the various obligations of
Microsoft hereunder, Data Return agrees to pay Microsoft a percentage of the
total gross Revenues as set forth in Exhibit C that Data Return receives from
third parties in consideration of its licensing and other exploitation of any
New Scripts for the five (5) years following acceptance of the relevant New
Script by Microsoft provided such script enables a solution for a customer that
extends beyond the basic functionality inherent in Commerce Server, Exchange
Server and/or Microsoft Office. For example, installation scripts designed to
assist in the deployment of Exchange Server as a secure document repository for
legal documents would pertain to Section 7, but installation scripts designed to
facilitate the deployment of Exchange Server as an outsourced messaging platform
would not. "Revenues" shall mean all kinds of consideration, including but not
limited to cash, barter and any other in-kind consideration. Data Return shall
submit such payments within forty-five (45) days after the end of each three
month period, the first three-month period commencing with the month in which
Microsoft accepts the New Script in accordance with Section 2.2. Such payment
shall be accompanied by a report in the form of an affidavit, reasonably
acceptable to Microsoft, detailing the sources and amount of Revenues for the
preceding three-month period.

9.      Contact Representatives.  Each party shall designate a contact to be
responsible for the administration of this Agreement.  Either party may change
its contact at any time upon notice to the other party. The initial contacts
are:  for Microsoft, David Ostroff and for Data Return, Sunny Vanderbeck.

10.     Press Releases.  The parties will cooperate with each other on press
releases and similar communications regarding the non-confidential subject
matter of this Agreement.  The content, timing and necessity of all such
communications will be agreed upon in writing by both parties.  At least one
press release shall be issued by Microsoft pertaining to this agreement, within
thirty (30) days of the execution of this agreement and with content to be
determined by the Contact Representatives named in Section 8.

11.     Audits.  During the term of this Agreement and for two (2) years
thereafter, Data Return agrees to keep all usual and proper records and books of
account and all usual and proper entries relating to the revenues it receives
from third parties in consideration of its licensing and other exploitation of
the Initial Scripts and New Scripts.  Microsoft may cause an audit and/or
inspection to be made of the applicable Data Return records in order to verify
statements issued by Data Return.  Any such audit shall be conducted by an
independent certified public accountant selected by Microsoft (other than on a
contingent fee basis).  Such independent certified public

                                                                    Page 4 of 12
<PAGE>

accountant shall provide a summary of its findings regarding its verification of
the statements issued by Data Return, but shall not provide Microsoft with any
other information produced from the audit of such Data Return records. Any audit
shall be conducted during regular business hours at Data Return's facilities
with at least three (3) business days' notice. Data Return agrees to provide
Microsoft's designated audit team access to the relevant Data Return records.
Data Return shall pay Microsoft the full amount of any underpayment revealed by
the audit from the date such payments were due under the terms of this
Agreement. Notwithstanding the foregoing, if such audit reveals an underpayment
by Data Return of more than ten percent (10%) for the period covered by the
audit report, Data Return shall pay the amount underpaid with interest at the
rate of the Prime Rate as announced by Seattle First National Bank of Seattle,
Washington (the "Prime Rate"), (or, if less, at a rate equal to the highest rate
permitted under applicable law from the date such payment was due pursuant to
this Section.

12.     No Obligation/Independent Development. Notwithstanding any other
provision of this Agreement, Microsoft shall have no obligation to market, sell
or otherwise distribute the Initial Scripts or New Scripts, either alone or in
any Microsoft product. Except as provided in Section 12, nothing in this
Agreement will be construed as restricting Microsoft's ability to acquire,
license, develop, manufacture or distribute for itself, or have others acquire,
license, develop, manufacture or distribute for Microsoft, similar technology
performing the same or similar functions as the technology contemplated by this
Agreement, or to market and distribute such similar technology in addition to,
or in lieu of, the technology contemplated by this Agreement.

13.     Confidentiality.  The parties acknowledge and agree that the terms and
conditions of the Microsoft Corporation Non-Disclosure Agreement (Reciprocal)
dated as of the same date as the Effective Date ("NDA") entered into by and
between the Parties are incorporated into this Agreement and that all of the
terms of this Agreement and all discussions and negotiations related thereto and
all nonpublic information exchanged pursuant hereto are considered Confidential
Information as defined in the NDA.

15.     Indemnity.

15.1    Indemnity.

        defend any claim or action brought against Microsoft, and Microsoft's
        subsidiaries, affiliates, directors, officers, employees, agents and
        independent contractors, which, if true, would constitute a breach of a
        warranty by Data Return in Section 14, and Data Return will indemnify
        and hold Microsoft harmless from and against any costs, damages and fees
        reasonably incurred by Microsoft, including but not limited to fees of
        attorneys and other professionals, that are attributable to such claim.

                                                                    Page 5 of 12
<PAGE>

        Return information, assistance and authority, at Data Return's expense,
        to help Data Return to defend such claim or action. Data Return will not
        be responsible for any settlement made by Microsoft without Data

        withheld.

        15.1.2   Microsoft shall have the right to employ separate counsel and
        participate in the defense of any claim or action. Data Return shall

        unreasonably withheld.

procure for Microsoft the right to continue use the Product, Deliverables or
portion thereof, as applicable, as licensed in this Agreement; or (ii) replace
or modify the Product, Deliverables or portion thereof with a version that is
non-infringing, provided that the replacement or modified version provides the
same material functionality as the allegedly infringing version. If (i) or (ii)

sums paid to Data Return by Microsoft under this Agreement.

18.2    Independent Contractors. Data Return is an independent contractor for
Microsoft, and nothing in this Agreement shall be construed as creating an
employer-employee relationship, a partnership, or a joint venture between the
parties.

18.3    Taxes.

                                                                    Page 7 of 12
<PAGE>

        18.3.1   The amounts to be paid by Data Return to Microsoft herein do
        not include any foreign, U.S. federal, state, local, municipal or other
        governmental taxes, duties, levies, fees, excises or tariffs, arising as
        a result of or in connection with the transactions contemplated under
        this Agreement including, without limitation, any state or local sales
        or use taxes or any value added tax or business transfer tax now or
        hereafter imposed on the provision of services to Data Return by
        Microsoft under this Agreement, regardless of whether the same are
        separately stated by Microsoft. All such taxes (and any penalties,
        interest, or other additions to any such taxes), with the exception of
        taxes imposed on Microsoft's net income or with respect to Microsoft's
        property ownership, shall be the financial responsibility of Data
        Return. Data Return agrees to indemnify, defend and hold Microsoft
        harmless from any such taxes or claims, causes of action, costs
        (including, without limitation, reasonable attorneys' fees) and any
        other liabilities of any nature whatsoever related to such taxes.

        18.3.2   Data Return will pay all applicable value added, sales and use
        taxes and other taxes levied on it by a duly constituted and authorized
        taxing authority on the software, services or other product provided
        under this Agreement or any transaction related thereto in each country
        in which the services and/or property are being provided or in which the
        transactions contemplated hereunder are otherwise subject to tax,
        regardless of the method of delivery. Any taxes that are owed by Data
        Return, (i) as a result of entering into this Agreement and the payment
        of the fees hereunder, (ii) are required or permitted to be collected
        from Data Return by Microsoft under applicable law, and (iii) are based
        upon the amounts payable under this Agreement (such taxes described in
        (i), (ii), and (iii) above the "Collected Taxes"), shall be remitted by
        Data Return to Microsoft, whereupon, upon request, Microsoft shall
        provide to Data Return tax receipts or other evidence indicating that
        such Collected Taxes have been collected by Microsoft and remitted to
        the appropriate taxing authority. Data Return may provide to Microsoft
        an exemption certificate acceptable to Microsoft and to the relevant
        taxing authority (including without limitation a resale certificate) in
        which case, after the date upon which such certificate is received in
        proper form, Microsoft shall not collect the taxes covered by such
        certificate.

        18.3.3   This tax section shall govern the treatment of all taxes
        arising as a result of or in connection with this Agreement
        notwithstanding any other section of this Agreement.

18.4    Governing Law. In the event an action is commenced to enforce a party's
rights under this Agreement, the prevailing party in such action shall be
entitled to recover its costs and reasonable attorneys' fees.  Data Return and
Microsoft each agree that this Agreement shall be governed by and interpreted in
accordance with the laws of the State of New York, U.S.A., and Data Return and
Microsoft hereby each consent to the jurisdiction of the state and federal
courts sitting in the state in which the other party's corporate headquarters is
located.  Both parties hereby agree that any lawsuit arising hereunder brought
by Data Return shall be brought exclusively in either the state or federal
courts sitting in the state in which the other party's corporate headquarters is
located.  Both parties waive all defenses of lack of personal jurisdiction and
forum inconveniens.  Process may be served on either party in the manner
authorized by applicable law or court rule.

18.5    Dispute Resolution. Notwithstanding the foregoing, in the event of a
disagreement between Microsoft and Data Return, the Contact Representatives will
first attempt to resolve the disagreement through negotiation.  In the event the
Representatives cannot resolve the disagreement within sixty (60) days, the
President or CEO of Data Return and a representative of the upper management of
Microsoft will attempt to resolve the disagreement through negotiation. In the
event that the President or CEO of Data Return and a Representative of upper
management of Microsoft are unable to resolve the dispute through negotiation
within thirty (30) days, the Parties will try in good faith to settle the
dispute by non-binding mediation under the Commercial Mediation Rules of the
American Arbitration Association, prior to the commencement of litigation.

18.6    Assignment. The authorization by Microsoft for Data Return to acquire
and distribute Initial Scripts in accordance with this Agreement is personal to
Data Return and this Agreement shall not be assignable by Data Return. Any
prohibited assignment is null and void. Microsoft may transfer its rights and
obligations hereunder to any third party without prior written approval of Data
Return.

18.7    Construction. If for any reason a court of competent jurisdiction finds
any provision of this Agreement, or portion thereof, to be unenforceable, that
provision of the Agreement will be enforced to the maximum extent permissible so
as to effect the intent of the parties, and the remainder of this Agreement will
continue in full force and effect. Failure by either party to enforce any
provision of this Agreement will not be deemed a waiver of future

                                                                    Page 8 of 12
<PAGE>

enforcement of that or any other provision. This Agreement has been negotiated
by the parties and their respective counsel and will be interpreted fairly in
accordance with its terms and without any strict construction in favor of or
against either party.

18.8    Entire Agreement. This Agreement supersedes and terminates any and all
prior agreements or contracts, written or oral, entered into between the parties
relating to the subject matter hereof, and any representations, promises, or
conditions in connection therewith not in writing shall not be binding upon
either party.  This Agreement shall be effective from the date first set forth
above, provided it has been properly executed on behalf of Microsoft and Data
Return by their duly authorized officers and accepted by Microsoft at its
Redmond, Washington offices.



IN WITNESS WHEREOF, the parties have entered into this Agreement as of the
Effective Date written above.

                                   Exhibit A

                                Initial Scripts

giving of notice or the passage of time or both)(i) conflict with or result in a
violation of any provision of the Company's Amended Articles of Incorporation
("Articles of Incorporation") or Bylaws or (ii) except to the extent that it
would not have a material adverse effect on the business, properties, assets,
operations, prospects, profits or condition (financial or otherwise) of the
Company (a "Material Adverse Effect"),(A) conflict with or result in a violation
of any provision of, or constitute a default under, or give rise to any right of

instrument or obligation to which the Company is a party or by which the Company
or any of the Company's properties may be bound or (B) result in the creation or

authority to own and operate its properties and assets, and to carry on its
business as presently conducted and as presently proposed to be conducted. The
Company is duly qualified and is authorized to do business and is in good
standing as a foreign corporation in all jurisdictions in which the nature of
its activities and of its properties (both owned and leased) makes such
qualification necessary, except for those jurisdictions in which failure to do
so would not have a Material Adverse Effect on the Company.

     (e)    Subsidiaries.  The Company owns no equity securities of any other
corporation, limited partnership, limited liability company or other entity. The
Company is not a participant in any joint venture, partnership or similar

have been duly authorized and validly issued, (ii) are fully paid and
nonassessable, and (iii) were issued in compliance with all applicable state and
federal laws concerning the issuance of securities.  Except as set forth in the

first refusal), proxy or shareholder agreements, or agreements, arrangements or
understandings of any kind, whether written or oral, for the issuance by the

            (G)  Any material change in any compensation arrangement or
agreement with any employee, officer, director, shareholder or agent not in the

            (H)  Any declaration or payment of any dividend or other

            (I)  Any labor organization activity, to the best of the Company's
knowledge;

            (J)  Any debt, obligation or liability incurred, assumed or
guaranteed by the Company, except for those for immaterial amounts and for
current liabilities incurred in the ordinary course of business;

            (K)  Any sale, assignment, transfer or license of any patents,
trademarks, copyrights, trade secrets or other intangible assets not in the
ordinary course of business;

            (L)  Any change in any material agreement to which the Company is a
party or by which it is bound,  which change would be reasonably likely to have
a Material Adverse Effect; or

            (M)  Any other event or condition of any character that, either
individually or cumulatively, has or, to the best of the Company's knowledge, is
reasonably likely to have a Material Adverse Effect.

     (l)    Title to Properties and Assets; Liens, etc. The Company has good and
marketable title to its properties and assets, including the properties and
assets reflected in the most recent balance sheet included in the Financial
Statements, and good title to its leasehold estates, in each case subject to no
mortgage, pledge, lien, lease, encumbrance or charge, other than (i) those
resulting from taxes which have not yet become delinquent, (ii) Encumbrances
that would not have a Material Adverse Effect, and (iii) those that have
otherwise arisen in the ordinary course of business. All facilities, machinery,
equipment, fixtures, vehicles and other properties owned, leased or used by the
Company are in good operating condition and repair and are reasonably fit and
usable for the purposes for which they are being used. The Company is in
compliance with all material terms of each lease to which it is a party or is
otherwise bound.

     (m)    Patents and Other Intangible Assets. The Company owns, or is
licensed or otherwise possesses sufficient legal rights to use, all patents,
trademarks, service marks, trade names, copyrights, trade secrets, licenses and
other proprietary rights and processes (the "Intellectual Property Rights") that
are material to the business of the Company as it is currently conducted. The
Company has not received any communication alleging that it has violated, or
that by conducting

                                      -6-
<PAGE>

its business as currently conducted would violate, any of the Intellectual
Property Rights of any other person or entity. No claims with respect to the
Company's Intellectual Property Rights have been asserted or are, to the best of
the Company's knowledge, threatened by any person or entity (i) challenging in
any way the use by the Company of any of the Company's Intellectual Property
Rights, (ii) challenging in any way the ownership by the Company of the
Company's Intellectual Property Rights or (iii) claiming any infringement of the
Intellectual Property Rights of any other person or entity. There are no
outstanding options, licenses or agreements of any kind relating to the
Company's Intellectual Property Rights, nor is the Company bound by or a party
to any options, licenses or agreements of any kind with respect to the
Intellectual Property Rights of any other person or entity, other than such
licenses or agreements arising from the purchase of "off-the-shelf" products. To
the best of the Company's knowledge, none of its employees is obligated under
any contract (including licenses, covenants or commitments of any nature) or
other agreement, or subject to any judgment, decree or order of any court or
administrative agency, that would interfere with their duties to the Company or
that would conflict with the Company's business as presently proposed to be
conducted. Neither the execution nor delivery of the Agreements, nor, to the
best of the Company's knowledge, the carrying on of the Company's business by
the employees of the Company, nor the conduct of the Company's business as
presently proposed will (with or without the giving of notice or the passage of
time or both) conflict with or result in a breach of the terms, conditions or
provisions of, or constitute a default under, any contract, covenant or
instrument under which any employee is now obligated. The Company does not
believe it is or will be necessary to utilize any inventions, trade secrets or
proprietary information of any of its employees made prior to their employment
by the Company.

     (n)    Compliance with Other Instruments.  The Company is not in violation
or default of any term of its Amended Articles of Incorporation or Bylaws, or of
any provision of any mortgage, contract, agreement, instrument or contract to
which it is party or by which it or any of its property or assets is bound or of
any judgment, decree, order, writ or, any statute, rule or regulation applicable
to the Company. Attached to the Disclosure Letter are true and correct copies of
the Company's Amended Articles of Incorporation and Bylaws.

     (o)    Litigation.  There is no action, suit, proceeding or investigation
pending, or to the best of the Company's knowledge threatened, against the
Company that questions the validity of the Agreements or the right of the
Company to enter into any of such agreements, or to consummate the transactions
contemplated hereby or thereby, or which (i) are reasonably likely to have,
either individually or in the aggregate, a Material Adverse Effect, or (ii)
might result in any change in the current equity ownership of the Company, nor,
to the best of the Company's knowledge, is there any basis for any of the
foregoing in this sentence. The foregoing includes, without limitation, actions
pending or threatened in writing (or any basis therefor known to the Company)
involving the prior employment of any of the Company's employees, their use in
connection with the Company's business of any information or techniques
allegedly proprietary to them or any of their former employers, or their
obligations under any agreements with prior employers. The Company is not a
party or subject to the provisions of any order, writ, injunction, judgment or
decree of any court or

                                      -7-
<PAGE>

government agency or instrumentality. There is no action, suit, proceeding or
investigation by the Company currently pending or which the Company intends to
initiate.

     (p)    Tax Returns and Payments.  Except to the extent that it would not
have a Material Adverse Effect, the Company: (i) has timely filed all tax
returns that are required to have been filed by it with all appropriate federal,
state, county and local governmental agencies (and all such returns fairly
reflect the Company's operations for tax purposes) and has timely paid all taxes
shown to be due and payable on such returns and any assessments imposed with
respect thereto; and (ii) has timely paid all taxes owed by it for which it is
obligated to withhold from amounts owing to any employee (including without
limitation social security taxes), creditor or third party (other than taxes the
validity of which are being contested in good faith by appropriate proceedings
and for which the Company has reserved against adequately). The Company has not
been advised (x) that any of its returns, federal, state or other, have been or
are being audited as of the date hereof, or (y) of any deficiency in assessment
or proposed judgment to its federal, state or other taxes. To the best of the
Company's knowledge, (i) there is no liability for any tax to be imposed upon it
or its properties or assets as of the date of this Agreement that is not
adequately provided for and (ii) all other taxes due and payable by the Company
on or before the Closing have been paid or will be paid prior to the time they
become delinquent.

     (q)    Employees.  The Company has no collective bargaining agreements with
any of its employees. There is no labor union organizing activity pending or, to
the best of the Company's knowledge, threatened with respect to the Company. No
employee has any agreement or contract, written or verbal, regarding his
employment. To the best of the Company's knowledge, no employee of the Company,
nor any consultant with whom the Company has contracted, is in violation of any
term of any employment contract, proprietary information agreement or any other
agreement relating to the right of any such individual to be employed by, or to
contract with, the Company because of the nature of the business to be conducted
by the Company; and to the best of the Company's knowledge the continued
employment by the Company of its present employees, and the performance of the
Company's contracts with its independent contractors, will not result in any
such violation. The Company has not received any notice alleging that any such
violation has occurred. No employee of the Company has been granted the right to
continued employment by the Company or to any material compensation following
termination of employment with the Company. The Company is not aware that any
officer or key employee, or that any group of key employees, intends to
terminate their employment with the Company, nor does the Company have a present
intention to terminate the employment of any officer, key employee or group of
key employees.

     (r)    Trade Secrets Agreements.  Each current employee and officer of the
Company has executed a Confidentiality and Trade Secrets Agreement and an
Employee Noncompete and Confidentiality Agreement in form and substance as
attached to the Disclosure Letter.  There are no other agreements or
understandings between the Company and any current employee or officer thereof
regarding proprietary information and/or inventions.

                                      -8-

     (s)    Registration Rights. Except as required pursuant to the Investor's
Rights Agreement, the Company is not under any obligation, and has not granted
any rights, to register any of the Company's presently outstanding securities or
any of its securities that may hereafter be issued.

     (t)    Compliance with Laws; Permits.  The Company is not in violation of
any applicable statute, rule, regulation, order or restriction of any domestic
or foreign government or any instrumentality or agency thereof in respect of the
conduct of its business or the ownership of its properties which violation is
reasonably likely to have a Material Adverse Effect. No governmental orders,
permissions, consents, approvals or authorizations are required to be obtained
and no registrations or declarations are required to be filed in connection with
the execution and delivery of the Agreements and the issuance of the Shares,
except for any filings pursuant to Federal or state securities laws (which
filings the Company will timely complete) and other governmental orders,
permissions, consents, approvals, authorizations, registrations or filings as
have been duly and validly obtained or filed. The Company has all franchises,
permits, licenses and any similar authority necessary for the conduct of its
business as now being conducted by it, the lack of any of which individually is
reasonably likely to have a Material Adverse Effect, and believes it can obtain,
without undue burden or expense, any similar authority for the conduct of its
business as planned to be conducted.

     (u)    Offering Valid.  Assuming the accuracy of the representations and
warranties of Buyer contained in Section 2.2(c), (d), (e), (f) and (g) hereof,
the offer, sale and issuance of the Shares will be exempt from the registration
requirements of the Securities Act and will have been registered or qualified
(or are exempt from registration and qualification) under the registration,
permit or qualification requirements of all applicable state securities laws.
Neither the Company nor any agent on its behalf has solicited or will solicit
any offers to sell or has offered to sell or will offer to sell all or any part
of the Shares to any person or persons so as to bring the sale of such Shares by
the Company within the registration provisions of the Securities Act or any
state securities laws.

     (v)    Environmental and Safety Laws.  To the best of the Company's
knowledge, there are no violations by the Company, its employees or agents of
any environmental or safety statute, law or regulation that individually or in
the aggregate would have a Material Adverse Effect, and, to the best of its
knowledge, no material expenditures are or will be required in order to comply
with any such existing statute, law or regulation.

     (x)    Insurance.  The Company maintains fire, casualty and liability
insurance policies, in such amounts and with such coverage as it believes are
reasonable for the business in which it is engaged.

     (y)    Brokers; Finders.  The Company has not authorized or retained any
person or entity to act as a broker or finder or in any similar capacity in
connection with the transactions contemplated by this Agreement.  The Company
shall indemnify and hold harmless Buyer from and against any and all losses,
claims, damages and liabilities (including legal and other expenses reasonably
incurred in connection with investigating or defending any claims or actions)
with respect

                                      -9-

to any finder's fee, brokerage commission or similar payment in connection with
any transaction contemplated hereby asserted by any person or entity on the
basis of any act or statement made or alleged to have been made by the Company.

     (z)    Accounting Controls.  Except to the extent that it would not have a
Material Adverse Effect, the Company maintains a system of internal accounting
controls sufficient to provide assurance that:  (i) all transactions are
executed in accordance with management's general or specific authorizations;
(ii) all transactions are recorded as necessary to permit preparation of
financial statements in conformity with generally accepted accounting principles
and to maintain accountability for assets; (iii) access to assets is permitted
only in accordance with management's general or specific authorization; and (iv)
the recorded accountability for assets is compared with the existing assets at
reasonable intervals and appropriate action is taken with respect to any
differences.

     2.2    Buyer Representations and Warranties.  Buyer hereby represents and
warrants to the Company that:

     (a)    Authority Relative to This Agreement.  Buyer has full legal right,
power and authority to execute, deliver and perform the Agreements and to
consummate the transactions contemplated thereby.  Each of the Agreements has
been duly executed and delivered by Buyer and constitutes, and each other
agreement, instrument, or document executed or to be executed by Buyer in
connection with the transactions contemplated hereby has been, or when executed
will be, duly executed and delivered by Buyer and constitutes, or when executed
and delivered will constitute, a valid and legally binding obligation of Buyer,
enforceable against Buyer in accordance with its respective terms, subject to
the laws of general application relating to bankruptcy, insolvency and relief of
debtors and applicable rules of law governing specific performance, injunctive
relief or other equitable remedies, and except that the enforceability of the
indemnification provisions in Section 1.6 of the Investor's Rights Agreement may
be limited by applicable securities laws.

     (b)    Noncontravention.  The execution, delivery and performance by Buyer
of the Agreements and the consummation by Buyer of the transactions contemplated
thereby do not and will not (with or without the giving of notice or the passage
of time or both) except to the extent it would not have a material adverse
effect on the business, assets or financial condition of Buyer (i) conflict with
or result in a violation of any provision of, or constitute a default under, or
give rise to any right of termination, cancellation, or acceleration under, any
contract, agreement, instrument or obligation to which Buyer is a party or by
which Buyer or any of Buyer's properties may be bound, or (ii) result in the
creation or imposition of any Encumbrance upon the property or assets of Buyer
or the suspension, revocation, impairment, forfeiture or nonrenewal of any
permit, license, authorization or approval applicable to the Buyer, its business
or operations or any of its assets or properties.

     (c)    Investment Intent.  Buyer is acquiring the Shares with its own funds
for its own account for investment and not with a view to any sale or other
disposition in connection with any

                                      -10-
<PAGE>

distribution of all or any part thereof and it has no present intention of
selling, granting participation in, or otherwise distributing the same, except
(i) in an offering covered by a registration statement filed with the Securities
and Exchange Commission under the Securities Act of 1933, as amended (the
"Securities Act"), covering the Shares or (ii) pursuant to an applicable
exemption under the Securities Act. By executing this Agreement, Buyer further
represents that Buyer does not have any contract, undertaking, agreement or
arrangement with any person to sell, transfer or grant participations to any
other parties with respect to the Shares.

     (d)    Disclosure of Information.  Buyer represents that it has had an
opportunity to ask questions of and receive answers from the Company regarding
the Company and its business, assets, results of operation and financial
condition and the terms and conditions of the issuance of the Shares.

     (e)    Investment Experience.  Buyer acknowledges that it is able to fend
for itself, can bear the economic risk of its investment in the Shares, and has
such knowledge and experience in financial and business matters that it is
capable of evaluating the merits and risks of an investment in the Shares. Buyer
represents that Buyer is an "Accredited Investor" for purposes of Regulation D
under the Securities Act.

     (f)    Restricted Securities.  Buyer understands that the Shares will not
have been registered pursuant to the Securities Act or any applicable state
securities laws, that the Shares will be characterized as "restricted
securities" under federal securities laws, and that under such laws and
applicable regulations the Shares cannot be sold or otherwise disposed of
without registration under the Securities Act or an exemption therefrom.  In
this connection, Buyer represents that it is familiar with Rule 144 promulgated
under the Securities Act, as currently in effect, and understands the resale
limitations imposed thereby and by the Securities Act.  Stop transfer
instructions may be issued to the transfer agent for securities of the Company
(or a notation may be made in the appropriate records of the Company) in
connection with the Shares for purposes of compliance with federal securities
laws.

     (g)    Legend.  It is agreed and understood by Buyer that the certificates
representing the Shares shall each conspicuously set forth on the face or back
thereof, in addition to any legends required by applicable law or other
agreement to which Buyer is a signatory, a legend in substantially the following
form:

     THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
     PURSUANT TO THE SECURITIES ACT OF 1933, AS AMENDED, OR ANY STATE SECURITIES
     LAWS.  SUCH SHARES MAY NOT BE SOLD OR OTHERWISE TRANSFERRED UNLESS THEY ARE
     FIRST REGISTERED PURSUANT TO THAT ACT AND APPLICABLE STATE SECURITIES LAWS
     UNLESS THE CORPORATION RECEIVES A WRITTEN OPINION OF COUNSEL, WHICH OPINION
     AND COUNSEL ARE REASONABLY SATISFACTORY TO THE CORPORATION, TO THE EFFECT
     THAT SUCH REGISTRATION IS NOT REQUIRED.

                                      -11-
<PAGE>

transactions made pursuant to Rule 144 under the Securities Act except in
unusual circumstances.

<PAGE>

                                                                       EXHIBIT A

                          INVESTOR'S RIGHTS AGREEMENT

     This Investor's Rights Agreement (this "Agreement") is made and entered
into as of July 29,1999, by and between Data Return Corporation, a Texas
corporation (the "Company"), and CPQ Holdings, Inc., a Delaware corporation
("Investor").

                                    RECITALS

     A.   Investor has agreed to purchase from the Company, and the Company has
agreed to sell to Investor, 4,356 shares (the "Shares") of the Company's Common
Stock pursuant to that certain Stock Purchase Agreement, dated of even date
herewith by and among the Company and Investor (the "Stock Purchase Agreement").

     B.   Investor has conditioned its purchase of the Shares on the Company
granting Investor certain registration and other rights, all as more fully set
forth herein.

     NOW, THEREFORE, in consideration of the foregoing recitals and the mutual
promises hereinafter set forth, the parties hereto agree as follows:

     1.   REGISTRATION RIGHTS.

          1.1    Definitions.   For purposes of this Agreement:

                 (a)  Common Stock. The term "Common Stock" means the common
stock of the Company, par value $.001 per share.

                 (b)  Exchange Act. The term "Exchange Act" means the Securities
and Exchange Act of 1934, as amended.

                 (c)  Holder. For purposes hereof, the term "Holder" means any
Investor holding Registrable Securities and any transferee or assignee of
Registrable Securities to whom the rights under this Section 1 have been
transferred or assigned in accordance with Section 3 of this Agreement.

                 (d)  Initiating Holder(s). The term "Initiating Holder(s)"
means (i) any Holders who in the aggregate are Holders of more than 50% of the
Registrable Securities or (ii) Investor.

                 (e)  Registrable Securities. The term "Registrable Securities"
means all the Shares and any additional Common Stock or other securities issued
as a dividend or other distribution with respect to, or in exchange for, or in
replacement of or in connection with such Common Stock, that are now owned or
may hereafter be acquired by Investor or Holder, excluding in all cases,
however, any Registrable Securities (y) sold by a person in a transaction in
which rights under this Section 1 are not assigned in accordance with this
Agreement or (z) sold
<PAGE>

in a registered public offering under the Securities Act or sold pursuant to
Rule 144 promulgated under the Securities Act.

                 (f)  Registration.  The terms "register," "registered," and
"registration" refer to a registration effected by preparing and filing a
registration statement in compliance with the Securities Act, and the
declaration or ordering of effectiveness of such registration statement by the
SEC.
                 (g)  SEC. The term "SEC" or "Commission" means the U.S.
Securities and Exchange Commission.

                 (h)  Securities Act. The term "Securities Act" means the
Securities Act of 1933, as amended.

          1.2    Piggyback Registrations. The Company shall notify all Holders
of Registrable Securities in writing at least 15 days prior to filing any
registration statement under the Securities Act for purposes of effecting a
public offering of securities of the Company (including, but not limited to,
registration statements relating to secondary offerings of securities of the
Company, but excluding registration statements relating to any employee benefit
plan, or with respect to a corporate reorganization or other transaction under
Rule 145 promulgated under the Securities Act) and will afford each such Holder
an opportunity to include in such registration statement all or any part of the
Registrable Securities then held by such Holder. Each Holder desiring to include
in any such registration statement all or any part of the Registrable Securities
held by such Holder shall, within 15 days after receipt of the above-described
notice from the Company, so notify the Company in writing, and in such notice
shall inform the Company of the number of Registrable Securities such Holder
wishes to include in such registration statement. If a Holder decides not to
include all of its Registrable Securities in any registration statement
thereafter filed by the Company, such Holder shall nevertheless continue to have
the right to include any Registrable Securities in any subsequent registration
statement or registration statements as may be filed by the Company with respect
to offerings of its securities, all upon the terms and conditions set forth
herein.

     If a registration statement under which the Company gives notice under
this Section 1.2 is for an underwritten offering, then the Company shall so
advise the Holders of Registrable Securities.  In such event, the right of any
such Holder's Registrable Securities to be included in a registration pursuant
to this Section 1.2 shall be conditioned upon such Holder's participation in
such underwriting and the inclusion of such Holder's Registrable Securities in
the underwriting to the extent provided herein.  All Holders proposing to
distribute their Registrable Securities through such underwriting shall enter
into an underwriting agreement in customary form with the managing underwriter
or underwriter(s) selected for such underwriting.  Notwith  standing any other
provision of this Agreement, if the managing underwriter determines in good
faith that marketing factors require a limitation of the number of shares to be
underwritten, then the managing underwriter(s) may, in their sole discretion,
exclude such portion of the shares (including Registrable Securities) that it
deems necessary from the registration and the underwriting, and the number of
shares that may be included in the registration and the underwriting shall be
allocated, first, to the Company, and second, to each person contractually
entitled to participate before the Holders, and third, to each of the Holders
requesting inclusion of

                                       2
<PAGE>

their Registrable Securities in such registration statement on a pro rata basis
based on the total number of Registrable Securities then held by each such
Holder. If any Holder disapproves of the terms of any such underwriting, such
Holder may elect to withdraw therefrom by written notice to the Company and the
underwriter. Any Registrable Securities excluded or withdrawn from such
underwriting shall be excluded and withdrawn from the registration.

          1.3    Demand Registration.

          (a)    If the Company shall receive at any time after the earlier of
(i) three years from the date hereof and (ii) 180 days after the effective date
of an initial public offering of its Common Stock ("IPO") a written request from
Initiating Holder(s), then the Company shall, within 20 business days of the
receipt of such written request, give written acknowledgment of such request
("Request Acknowledgment") to all Holders, and use its best efforts to effect,
as soon as practicable, the registration under the Securities Act of all
Registrable Securities then owned of record by all Holders and which such
Holders request to be registered and included in such registration by written
notice given by such Holders to the Company within 20 days after receipt of the
Request Acknowledgment; provided, however, that the Company shall not be
obligated to effect any such registration, qualification or compliance pursuant
to this Section 1.3:

                 (i)    if the aggregate value of the Registrable Securities
     proposed to be sold by such Holders in such offering is less than
     $1,000,000;

                 (ii)   if such offering would (y) require disclosure of
     material nonpublic information that the Board of Directors of the Company
     determines in good faith would be in the best interests of the Company not
     to disclose or (z) have a material adverse effect (as determined by the
     Board of Directors in good faith) on the Company or its shareholders in
     relation to any financing, acquisition, corporate reorganization or other
     material transaction actively pursued by the Board of Directors of the
     Company, involving the Company or any of its affiliates, in which event, in
     the case of both (y) and (z), the Company shall have the right to defer the
     filing of the registration statement no more than once during any 12-month
     period for a period of not more than 120 days after receipt of the request
     of such Holders under this Section 1.3 (the Company must furnish to the
     Holders requesting registration a certificate signed by its Chairman of the
     Board of Directors, Chief Executive Officer or Chief Financial Officer
     certifying as to any such determination made by the Board of Directors);

                 (iii)   if the request is made during the period starting with
     the filing of, and ending on a date 90 days following the effective date
     of, a registration statement pertaining to an underwritten public offering
     of securities for the account of the Company, provided that the Company is
     actively employing in good faith all reasonable efforts to cause such
     registration statement to become effective; or

                 (iv)   The Company is obligated to effect only one such
     registration pursuant to this Section 1.3 (which registration must be
     declared or ordered effective).

                                       3
<PAGE>

                 (b)  If Initiating Holder(s) submit a registration request
under this Section 1.3 and intend to distribute the Registrable Securities
covered by such request by means of an underwriting (an "Underwritten
Offering"), then the Initiating Holder(s) shall so advise the Company as a part
of the request made pursuant to this Section 1.3 and the Company shall include
such information in the written notice referred to in Section 1.3(a). In such
event, the right of Investor and the other Holders to include their Registrable
Securities in such registration shall be conditioned upon such Holders'
participation in such underwriting and the inclusion of the Holders' Registrable
Securities in the underwriting to the extent provided herein. If Investor or the
other Holders propose to distribute their securities through such underwriting,
they shall enter into an underwriting agreement in customary form with the
managing underwriter or underwriters selected for such underwriting by a
majority in interest of the Initiating Holder(s) from a list of three
nationally-recognized underwriters proposed by the Company. Any Registrable
Securities excluded and withdrawn from such underwriting shall be withdrawn from
the registration. If the representative of such underwriters determines in good
faith that marketing factors require a limitation of the number of shares to be
underwritten and so advises Investor and the Holders in writing, the Registrable
Securities to be sold by Investor shall be the last securities (including any
other registrable securities of any other shareholder with registration rights)
to be excluded from such registration.

          1.4    Obligations of the Company.

                 (a)  Expenses.

                      (i)   All expenses incurred in connection with a
     registration pursuant to Section 1.2 including, without limitation, all
     registration and qualification fees, printers' and accounting fees, fees
     and disbursements of counsel for the Company, and reasonable fees and
     expenses of one special counsel for the selling Holders (up to a maximum of
     $25,000) (but excluding underwriters' and brokers' discounts and
     commissions with respect to Registrable Securities to be sold by Holders),
     shall be borne by the Company. Each Holder participating in a registration
     pursuant to Section 1.2 of this Agreement shall bear such Holder's
     proportionate share (based on the total number of shares sold in such
     registration other than for the account of the Company) of all underwriting
     discounts or commissions payable to underwriters or brokers in connection
     with such offerings with respect to Registrable Securities to be sold by
     Holders.

                      (ii)  All expenses incurred in connection with a
     registration pursuant to Section 1.3 including, without limitation, all
     registration and qualification fees, printers' and accounting fees, fees
     and disbursements of counsel for the Company, and fees and expenses of
     counsel for the selling Holders, including underwriters' and brokers'
     discounts and commissions with respect to Registrable Securities to be sold
     by Holders, shall be borne by the selling Holders; provided, however, that
     the Company shall pay (i) all of its accounting fees and fees and
     disbursements of counsel for the Company that are, in the aggregate,
     greater than $250,000 and (ii) compensation to its employees. Each Holder
     participating in a registration pursuant to Section 1.3 of this Agreement
     shall bear

                                       4
<PAGE>

     such Holder's proportionate share (based on the total number of shares sold
     in such registration other than for the account of the Company) of all such
     expenses.

                 (b)  Registration. Whenever required to effect the registration
of any Registrable Securities under this Agreement, the Company shall:

                      (i)   Prepare and file with the SEC a registration
     statement with respect to such Registrable Securities and use its best
     efforts to cause such registration statement to become effective (provided,
     that the Company shall not be required to use such efforts with respect to
     a registration pursuant to Section 1.2), and, upon the request of the
     Holders of a majority of the Registrable Securities registered thereunder,
     keep such registration statement effective for (y) with respect to a
     registration statement filed on the SEC Form S-3 or any replacement form
     thereof, 120 days with respect to an offering initiated by the Holders or
     for the period contemplated by the plan of distribution in the case of a
     registration initiated by the Company or another shareholder or until the
     Holders, as applicable, have completed the distribution described in the
     registration statement relating thereto, whichever first occurs and (z)
     with respect to a registration statement filed on any other SEC form
     (including the SEC's Form S-1 or any replacement form thereof) 60 days with
     respect to an offering initiated by the Holders or for the period
     contemplated by the plan of distribution in the case of a registration
     initiated by the Company or another shareholder or until the Holders, as
     applicable, have completed the distribution described in the registration
     statement relating thereto, whichever first occurs plus any additional
     periods represented by any "Black-Out Period" (as defined in the last
     paragraph of Section 1.4(b)(vi)).

                      (ii)  Prepare and file with the SEC such amendments and
     supplements to such registration statement and the prospectus used in
     connection with such registration statement as may be necessary to comply
     with the provisions of the Securities Act with respect to the disposition
     of all securities covered by such registration statement.

                      (iii) Furnish to the Holders such number of copies of a
     prospectus, including a preliminary prospectus, in conformity with the
     requirements of the Securities Act, and such other documents as they may
     reasonably request in order to facilitate the disposition of the
     Registrable Securities owned by them that are included in such
     registration.

                      (iv)  Use its best efforts to register and qualify the
     securities covered by such registration statement under such other
     securities or blue sky laws of such jurisdictions as shall be reasonably
     requested by the Holders, provided that the Company shall not be required
     in connection therewith or as a condition thereto to qualify to do business
     or to file a general consent to service of process in any such states or
     jurisdictions.

                      (v)   In the event of any underwritten public offering,
     enter into and perform its obligations under an underwriting agreement, in
     usual and customary form,

                                       5
<PAGE>

     with the managing underwriter(s) of such offering. Each Holder
     participating in such underwriting shall also enter into and perform its
     obligations under such an agreement.

                      (vi)    Notify each Holder, at any time when a prospectus
     relating thereto is required to be delivered under the Securities Act, of
     the happening of any event as a result of which the prospectus included in
     such registration statement contains an untrue statement of a material fact
     or omits any fact required to be stated therein or necessary to make the
     statements therein not misleading, and, at the request of the Holder, the
     Company will prepare a supplement or amendment to such prospectus so that,
     as thereafter delivered to the purchasers of such Registrable Securities,
     such prospectus will not contain an untrue statement of a material fact
     required to be stated therein or omit to state any fact necessary to make
     the statements therein not misleading, or of the determination by the
     Company that a post-effective amendment to a registration statement would
     be required under the Securities Act, and, at the request of the Holder,
     the Company will prepare and file a post-effective amendment to the
     registration statement as required under the Securities Act; provided,
     however, that the Company may postpone preparing and delivering any such
     prospectus supplement or amendment or preparing and filing any post-
     effective amendment to a registration statement if the Board of Directors
     of the Company in good faith determines that such prospectus supplement or
     amendment or post-effective amendment (A) would have a material adverse
     effect on any active proposal or plan by the Company to engage in any
     acquisition of assets (other than in the ordinary course) or any merger,
     consolidation, tender offer or similar transaction, or (B) would require
     disclosure of material nonpublic information that would be in the best
     interests of the Company not to disclose; provided, that the Company shall
     have such right to postpone no more than once during any 12-month period
     for a period of not more than 120 days. Any such postponement under this
     Section shall count as a deferral under Section 1.3(a)(ii), and vice versa.
     The period during which the Company exercises its rights as described in
     this paragraph to postpone, delay or interrupt the offer and sale of the
     Registrable Securities or during the pendency of any stop order, injunction
     or other order or requirement of the SEC or any other governmental agency
     or court shall be referred to herein as "Black-out Period".

                      (vii)   Furnish, at the request of any Holder requesting
     registration of Registrable Securities, on the date that such Registrable
     Securities are delivered to the underwriters for sale, if such securities
     are being sold through underwriters, or, if such securities are not being
     sold through underwriters, on the date that the registration statement with
     respect to such securities becomes effective, an opinion, dated as of such
     date, of the counsel representing the Company for the purposes of such
     registration, in form and substance as is customarily given to underwriters
     in an underwritten public offering and reasonably satisfactory to such
     underwriters, addressed to the underwriters, if any, and to the Holders
     requesting registration of Registrable Securities.

                      (viii)  Use its best efforts to cause a "comfort" letter,
     dated as of such date, from the independent certified public accountants of
     the Company, to be issued in form and substance as is customarily given by
     independent certified public accountants to

                                       6
<PAGE>

     underwriters in an underwritten public offering and reasonably satisfactory
     to Holders, addressed to the underwriters, if any, and to the Holders
     requesting registration of Registrable Securities.

          1.5    Furnish Information.  It shall be a condition precedent to the
obligations of the Company to take any action pursuant to Sections 1.2 or 1.3
that the selling Holders shall furnish to the Company such information regarding
themselves, the Registrable Securities held by them, and the intended method of
disposition of such securities and such other information as the Company may
reasonably request to timely effect the registration of their Registrable
Securities.

          1.6    Indemnification.  In the event any Registrable Securities are
included in a registration statement under Sections 1.2 or 1.3:

                 (a)  By the Company. To the extent permitted by law, the
Company will defend, indemnify and hold harmless Investor and each other Holder,
the shareholders, members, managers, partners, officers and directors of
Investor and each other Holder, any underwriter (as defined in the Securities
Act) for Investor and each such other Holder and each person, if any, who
controls Investor or any such other Holder or underwriter within the meaning of
the Securities Act or the Exchange Act against any losses, claims, damages or
liabilities (joint or several) to which they may become subject under the
Securities Act, the Exchange Act or other federal or state law, insofar as such
losses, claims, damages or liabilities (or actions in respect thereof) arise out
of or are based upon any of the following statements, omissions or violations
(collectively a "Violation"):

                      (i)     any untrue statement or alleged untrue statement
     of a material fact contained in such registration statement, including any
     preliminary prospectus or final prospectus contained therein or any
     amendments or supplements thereto;

                      (ii)    the omission or alleged omission to state therein
     a material fact required to be stated therein, or necessary to make the
     statements therein not misleading; or

                      (iii)   any violation or alleged violation by the Company
     of the Securities Act, the Exchange Act, any federal or state securities
     law or any rule or regulation promulgated under the Securities Act, the
     Exchange Act or any federal or state securities law in connection with the
     offering covered by such registration statement,

and the Company will reimburse Investor and each other such Holder and such
other indemnitees for any legal or other expenses reasonably incurred by them,
as incurred, in connection with investigating or defending any such loss, claim,
damage, liability or action; provided however, that the indemnity agreement
contained in this Section 1.6(a) shall not apply to amounts paid in settlement
of any such loss, claim, damage, liability or action if such settlement is
effected without the consent of the Company (which consent shall not be
unreasonably withheld), nor shall the Company be liable in any such case for any
such loss, claim, damage, liability or action to the extent that it arises out
of or is based upon a Violation which occurs in reliance upon and

                                       7
<PAGE>

in conformity with written information furnished expressly for use in connection
with such registration by such Holder, or partner, officer, director or
controlling person of such Holder.

          (b)  By Selling Holders.  To the extent permitted by law, each selling
Holder will defend, indemnify and hold harmless the Company, each of its
directors, each of its officers who have signed the registration statement, each
person, if any, who controls the Company within the meaning of the Securities
Act or the Exchange Act, any underwriter, each person, if any, who controls such
underwriter within the meaning of the Securities Act or the Exchange Act, and
any other Holder selling securities under such registration statement or any of
such other Holder's partners, directors or officers or any person who controls
such Holder within the meaning of the Securities Act or the Exchange Act,
against any losses, claims, damages or liabilities (joint or several) to which
the Company or any such director, officer, underwriter or other such Holder,
partner, or director, officer or controlling person of the Company, such
underwriter or such other Holder may become subject under the Securities Act,
the Exchange Act or other federal or state securities law, insofar as such
losses, claims, damages or liabilities (or actions in respect thereof) arise out
of or are based upon any Violation, in each case to the extent (and only to the
extent) that such Violation occurs in reliance upon and in conformity with
written information furnished by such Holder expressly for use in connection
with such registration; and each such Holder will reimburse any legal or other
expenses reasonably incurred by the Company or any such director, officer,
controlling person, underwriter or other Holder, partner, officer, director or
controlling person of such other Holder in connection with investigating or
defending any such loss, claim, damage, liability or action; provided, however,
that the indemnity agreement contained in this Section 1.6(b) shall not apply to
amounts paid in settlement of any such loss, claim, damage, liability or action
if such settlement is effected without the consent of the Holder, which consent
shall not be unreasonably withheld; and provided further, that the total amounts
payable in indemnity and reimbursement by a Holder under this Section 1.6(b) in
respect of all Violations shall not exceed the proceeds (net of underwriters'
and brokers' discounts and commissions) received by such Holder in the
registered offering out of which such Violations arise.

          (c)  Notice.  Promptly after receipt by an indemnified party under
this Section 1.6 of notice of the commencement of any action (including any
governmental action), such indemnified party will, if a claim in respect thereof
is to be made against any indemnifying party under this Section 1.6, deliver to
the indemnifying party a written notice of the commencement thereof and the
indemnifying party shall have the right to participate in, and, to the extent
the indemnifying party so desires, jointly with any other indemnifying party
similarly noticed, to assume the defense thereof with counsel mutually
satisfactory to the parties; provided, however, that an indemnified party shall
have the right to retain its own counsel, with the fees and expenses to be paid
by the indemnifying party, if representation of such indemnified party by the
counsel retained by the indemnifying party would be inappropriate due to actual
or potential conflict of interests between such indemnified party and any other
party represented by such counsel in such proceeding; and provided, further,
that under no circumstances shall the indemnifying party be required to pay the
fees and expenses of more than one counsel for all indemnified parties. The
failure to deliver written notice to the indemnifying party within a reasonable
time of the commencement of any such action, if materially prejudicial to its
ability to defend such action, shall relieve such indemnifying party of
liability to the extent caused by such

                                       8
<PAGE>

failure to deliver written notice to the indemnified party under this Section
1.6, but the omission so to deliver written notice to the indemnifying party
will not relieve it of any liability that it may have to any indemnified party
otherwise than under this Section 1.6.

          (d)  Contribution.  If the indemnification provided in this Section
1.6 is unavailable or insufficient to hold harmless an indemnified party under
Section 1.6(a) or (b), then each indemnifying party shall contribute to the
amount paid or payable by such indemnified party as a result of the losses,
claims, damages or liabilities referred to above (i) in such proportion as is
appropriate to reflect the relative benefits received by the indemnifying party
on the one hand and the indemnified party on the other from the offering of the
securities or (ii) if the allocation provided by clause (i) above is not
permitted by applicable law, in such proportion as is appropriate to reflect not
only the relative benefits referred to in clause (i) above but also the relative
fault of the indemnifying party on the one hand and the indemnified party on the
other in connection with the Violations that resulted in such losses, claims,
damages or liabilities, such relative fault to be determined considering, among
other items, the relative access to information and opportunity to correct or
prevent misstatements or omissions of each party, as well as any other equitable
considerations. Notwithstanding the provisions of this section, no selling
Holder shall be required to contribute any amount in excess of the amount of the
total net proceeds (net of underwriters' and brokers' discounts and commissions)
received by such Holder in the registered offering out of which the Violation
arises. No person guilty of fraudulent misrepresentation (within the meaning of
Section 11(f) of the Securities Act) shall be entitled to contribution from any
person who is not guilty of such fraudulent misrepresentation.

          (f)    Survival.  The obligations of the Company and selling Holders
under this Section 1.6 shall survive the completion of any offering of
Registrable Securities in a registration statement, the termination of this
Agreement and otherwise.

     1.7  "Market Stand-Off" Agreement.  Each Holder hereby agrees that it
shall not, without the consent of the managing underwriter, sell, transfer,
pledge, hypothecate or otherwise transfer or dispose of any Registrable
Securities or other shares of stock of the Company then owned by such Holder
(other than those included in an applicable registration and other than to
donees or partners of the Holder who agree to be similarly bound) for up to 180
days following the effective date of a registration statement (other than a
registration statements relating to any employee benefit plan, or with respect
to a corporate reorganization or other transaction under Rule 145 promulgated
under the Securities Act )of the Company for an IPO filed under the Securities
Act; provided, however, that all officers and directors of the Company and all
holders of Common Stock (or options or other rights to acquire Common Stock)
equal to at least 1% of the Company's voting securities (on a fully-diluted
basis) enter into similar agreements.  In order to enforce the foregoing
covenant, the Company shall have the right to place restrictive legends on the
certificates representing the shares subject to this Section and to impose stop
transfer instructions with respect to the Registrable Securities and such other
shares of stock of each Holder (and the shares or securities of every other
person or entity subject to the foregoing restriction).

                                       9
<PAGE>

          1.8    Rule 144 Reporting. With a view to making available the
benefits of certain rules and regulations of the Commission which may at any
time permit the sale of the Registrable Securities to the public without
registration, the Company agrees to:

                 (a)  Make and keep public information available, as those terms
are understood and defined in Rule 144 under the Securities Act or any similar
or analogous rule promulgated under the Securities Act, at all times after the
effective date of the first registration under the Securities Act filed by the
Company for an offering of its securities to the general public; and

                 (b)  Use its best efforts to file with the Commission in a
timely manner all reports and other documents required of the Company under the
Securities Act and the Exchange Act (at any time after it has become subject to
such reporting requirements).

                 (c)  So long as a Holder owns any Registrable Securities,
furnish to such Holder upon written request: a written statement by the Company
as to its compliance with the provisions of clauses (a) and (b); a copy of the
most recent annual or quarterly report of the Company; and such other reports
and documents as a Holder may reasonably request in availing itself of any rule
or regulation of the SEC allowing it to sell any such securities without
registration.

          1.9    Termination of the Company's Obligations. The Company shall
have no obligations pursuant to Sections 1.2 or 1.3 with respect to the
Registrable Securities of a Holder if in the reasonable written opinion of
counsel to the Company (which opinion shall also be addressed and provided to
the Holders), all Registrable Securities then owned by or issuable to such
Holder (and its affiliates, partners, former partners, members and former
members) may be sold in one three month period without registration under the
Securities Act pursuant to Rule 144 under the Securities Act (without giving
effect to the provisions of Rule 144(k)).

     2.   RIGHT OF FIRST REFUSAL.

          2.1    General. As long as Investor or any other Holder continues to
own any Registrable Securities, Investor or such other Holder shall have the
right of first refusal to purchase Investor's then-current Pro Rata Share (as
defined below), of all (or any part) of any "New Securities" (as defined in
Section 2.2) that the Company may from time to time propose to issue after the
date of this Agreement. An Investor's "Pro Rata Share" for purposes of this
right of first refusal shall mean, at any time of determination, the ratio of
(a) the number of Registrable Securities owned by Investor to (b) that number of
shares of Common Stock of the Company then outstanding.

          2.2    New Securities. "New Securities" shall mean, whether now
authorized or not, any capital stock of the Company, any rights, options or
warrants to purchase or acquire such capital stock, and securities of any type
whatsoever that are, or may become, convertible or exchangeable into such
capital stock; provided, however, that the term "New Securities" does not
include:

                                       10
<PAGE>

                 (a)  shares of Common Stock (and/or options or warrants
therefor) issued after the date of this Agreement to employees, officers,
directors, contractors, advisors or consultants of the Company pursuant to
agreements or plans approved by the Board of Directors of the Company.

                 (b)  shares of the Company's capital stock issued in connection
with any stock split or stock dividend;

                 (c)  securities offered by the Company to the public pursuant
to its IPO; or

                 (d)  securities issued for consideration other than cash
pursuant to the acquisition of another corporation or entity by the Company by
consolidation, merger, purchase of all or substantially all of the assets, or
other business combination in which the Company acquires, in a single
transaction or series of related transactions, all or substantially all of the
assets of such other corporation or entity or more than 50% of the voting power
of such other corporation or entity or more than 50% of the equity ownership of
such other entity.

          2.3    Procedures. In the event that the Company proposes to undertake
an issuance of New Securities, it shall give to Investor written notice of its
intention to issue New Securities (the "Notice"), describing the type of New
Securities and the price and the general terms upon which the Company proposes
to issue such New Securities. Investor shall have 20 days from the date of
receipt of any such Notice to agree in writing to purchase Investor's Pro Rata
Share of such New Securities for the price and upon the general terms specified
in the Notice by giving written notice to the Company and stating therein the
quantity of New Securities to be purchased (not to exceed such Investor's Pro
Rata Share).

          2.4    Termination. This right of first refusal shall terminate upon
the earlier to occur of (i) the closing of its IPO; or (ii) (a) the acquisition
of all or substantially all the assets of the Company by another unaffiliated
entity or (b) an acquisition of the Company by an unaffiliated corporation or
person by share purchase, consolidation, merger or other business combination in
which the holders of the Company's outstanding voting stock immediately prior to
such transaction own, immediately after such transaction, securities
representing less than 50% of the voting power of the corporation or other
entity surviving such transaction pursuant to this Section 2.

     3.   ASSIGNMENT.

     The rights to cause the Company to register Registrable Securities pursuant
to Section 1 and the rights of first refusal contained in Section 2 may be
assigned by Investor or any other Holder to a transferee or assignee of
Registrable Securities which (a) is a subsidiary, parent, general partner,
limited partner, retired partner, member or retired member of a Holder, (b) is a
Holder's family member or trust for the benefit of an individual Holder, (c) is
a Holder of any Registrable Securities or (d) acquires at least 20% of the
Registrable Securities (as adjusted for stock splits and dividends); provided,
however, (i) the transferor shall, within 10 days after such transfer, furnish
to the Company written notice of the name and address of such transferee or
assignee and the securities with respect to which such registration or first
refusal rights are being

                                       11
<PAGE>

assigned and (ii) such transferee shall agree to be subject to all restrictions
set forth in this Agreement.

     4.   AFFIRMATIVE COVENANTS OF THE COMPANY

     The Company hereby covenants and agrees as follows:

     4.1  Financial Information. Subject to Section 4.3, the Company will mail
the following reports to the Investor or any other Holder for so long as the
Investor or any other Holder is a Holder of any Registrable Securities:

event within 90 days thereafter, consolidated balance sheets of the Company and
its subsidiaries, if any, as of the end of such fiscal year, and consolidated
statements of operations and consolidated statements of cash flows of the
Company and its subsidiaries, if any, for such year prepared in accordance with
generally accepted accounting principles and setting forth in each case in
comparative form similar information for the previous fiscal year, all in
reasonable detail and audited by independent public accountants of national
standing selected by the Company's Board of Directors.  Such financial
statements shall be accompanied by a report and opinion thereon from such
accountants.

     (b)  As soon as practicable after the end of the first, second and third
quarterly accounting periods in each fiscal year of the Company and in any event
within 45 days thereafter, a consolidated balance sheet of the Company and its
subsidiaries, if any, as of the end of each such quarterly period, and
consolidated statements of operations and consolidated statements of cash flows
of the Company and its subsidiaries, if any, for such period and for the current
fiscal year to date, prepared in accordance with GAAP (other than for
accompanying notes), all in reasonable detail and certified by the principal
financial or accounting officer of the Company, subject to changes resulting
from year-end audit adjustments.

     (c)  Contemporaneously with their delivery to holders of the Company's
Common Stock, a copy of each report or other communication delivered to holders

     4.2  Additional Information.  Subject to Section 4.3, as long as Investor
or any other Holder holds any Registrable Securities, the Company will deliver

     (a)  Within 30 days prior to the beginning of each fiscal year, an "Annual
Plan." The Annual Plan shall set forth full and complete forecasted balance
sheets, statements of operations, and statements of cash flows for such fiscal
year and for each month within that year. The Annual Plan shall also describe
the marketing, production, research and development, organization and staffing,
and financial strategies which support the Annual Plan's forecasted figures.

     (b)  With reasonable promptness, such other information and data with
respect to the Company and its subsidiaries, if any, as the Investor may from
time to time reasonably request.

                                       12
<PAGE>

     (c)  For so long as Investor or any other Holder is eligible to receive
reports under this Section 4.2, it shall also have the right, at its expense, to
visit and inspect any of the properties of the Company or any of its
subsidiaries, to examine its books of account and records, and to discuss their
affairs, finances and accounts with their officers, all at such reasonable times
as often as may be reasonably requested.

     4.3  Termination of Covenants. The covenants set forth in Sections 4.1 and
4.2 shall terminate and be of no further force or effect at such time as the
Company is required to file reports pursuant to Sections 13 or 15(d) of the
Exchange Act.

such provision(s) were so excluded and shall be enforceable in accordance with
its terms.

        5.9 Entire Agreement.  This Agreement and the documents referred to
herein constitute the entire agreement among the parties and no party shall be
liable or bound to any other party in any manner by any warranties,
representations, or covenants except as specifically set forth herein or
therein.

and sale by the Company of the Shares to Investor.

        5.11   No Inconsistent Agreements.  The Company shall not, after the
date of this Agreement, enter into any agreement with respect to any of its
securities that is inconsistent with the rights granted to Investor or the other
Holders in this Agreement or otherwise

the preceding sentence, after the date of this Agreement, the Company shall not,
without the prior written consent of Investor and the Holders of a majority of
the Registrable Securities then outstanding, enter into any agreement with any
holder or prospective holder of any securities of the Company that would grant
such holder registration rights senior to those granted to Investor and Holders
hereunder.
